Description

Cooking Appliance{COOKING APPLIANCE}

The present invention relates to a cooking appliance, and more specifically, to a cooking appliance provided with a door for opening and closing a cooking chamber.

A cooking appliance is a type of home appliance used to cook food and is installed in a kitchen space to cook food according to the user's intention. These cooking appliances can be classified in various ways depending on the heat source or type used and the type of fuel.

When classifying cooking appliances according to the type of space where plants are placed, cooking appliances can be classified into open cooking appliances and closed cooking appliances. Closed cooking appliances include ovens and microwave ovens. And open cooking appliances include cooktops, hobs, and griddles.

A closed cooking appliance is a cooking appliance that shields the space where food is located. These sealed cooking appliances can cook food by heating a shielded space.

Inside the closed cooking appliance, a cooking chamber is provided. The galley is a space where food is placed and a space where cooking appliances are shielded when cooking food. This galley is actually a space where food is cooked.

In closed cooking appliances, a rotatable door is provided to selectively open and close the cooking chamber. The door may be rotatably installed in the main body by a door hinge provided between the main body with a cooking chamber formed therein and the door. This door can selectively open and close the galley by rotating around the part that is coupled to the main body through the door hinge.

A heat source may be provided in the interior space of the cooking compartment that is opened and closed by the door. The heat source is provided to heat the cooking chamber. A gas burner or electric heater may be used as such a heat source.

In the upper part of the galley, an electronics room may be placed. The electrical components room may be equipped with electrical components necessary for the operation of the sealed cooking appliance. This battlefield room is formed as a space separated from the galley.

Inside the battlefield, a cooling fan may be provided to cool the battlefield. The cooling fan may be provided in the form of a centrifugal fan, such as a sirocco fan, and may be disposed biased toward the rear of the battlefield.

This cooling fan can cool the battlefield by sucking in external air and forcing it into the interior of the battlefield, and forcibly discharging the hot air inside the battlefield to the outside.

The main body may include a cavity and a front panel. The cavity forms the skeleton of the main body, and a cooking chamber may be formed inside the cavity. The front panel may be disposed in front of the cavity to form the front of the main body.

The electronics compartment may be placed at the top of the cavity. And the front of the battlefield can be shielded by the front panel. For example, at least a portion of the front panel may protrude above the cavity, and the upper area of the front panel disposed above the cavity may shield the front of the electrical equipment room.

In the front panel, an exhaust port may be provided. The exhaust port may be formed to penetrate the front panel in the front-to-back direction. These exhaust ports can form a passage on the front panel for the air inside the battlefield to be discharged to the outside.

The exhaust port may be placed in the front of the electronics compartment, that is, in the upper area of the front panel. And on the front side of the exhaust port, a discharge passage may be formed. A control panel and a door may be disposed on the front side of the exhaust port, and a gap of a predetermined height may be formed between the control panel and the door disposed in the vertical direction. A discharge passage may be formed in the gap between the control panel and the door.

The exhaust port is exposed to the discharge passage side and may be connected to the discharge passage. Additionally, at least a portion of the exhaust port may be exposed to the front of the cooking appliance through this discharge passage. That is, at least a portion of the exhaust port may be exposed to the front through the gap between the control panel and the door.

Air introduced into the battlefield by a cooling fan inside the battlefield may be discharged to the outside of the battlefield through an exhaust port. And the air discharged through the exhaust port can be discharged to the front of the cooking appliance through the discharge passage between the control panel and the door.

Meanwhile, heat inside the cooking chamber generated during the cooking process may be transmitted to the outside of the door through the door. To shield this conductive heat, a plurality of glasses may be installed on the door.

For example, a front glass disposed on the outer side of the door and a rear glass disposed on the inner side of the door may be installed on the door, and a plurality of intermediate glasses may be installed between the front glass and the rear glass. Each intermediate glass may be provided with a radiation-reflective coating for heat shielding.

The heat inside the galley is transferred to the inner side of the door and then to the front glass through the middle glass inside the door. The conductive heat can be shielded by the radiant energy reflecting coating of the inner glass.

Additionally, a discharge hole may be provided at the top of the door. The discharge hole may be formed to penetrate the top of the door in a vertical direction. Through these discharge holes, hot air inside the door can be discharged into the discharge passage. At the same time, cold air may be sucked into the lower part of the door, where hot air has escaped.

That is, the door can be cooled by an air flow in which hot air inside the door is discharged through the top of the door and cold air is introduced into the inside of the door through the bottom of the door.

As described above, the discharge hole is disposed at the top of the door. In this way, the discharge hole disposed at the top of the door may be connected to the discharge passage. In other words, hot air discharged through the exhaust port and hot air discharged through the discharge hole may merge in the discharge passage.

The hot air discharged from the inside of the electrical room through the exhaust port may pass through the discharge passage and the upper area of the discharge hole before being discharged to the outside of the cooking appliance. In this process, the hot air flowing inside the discharge passage may flow back into the door through the discharge hole.

In other words, a phenomenon may occur where the air discharged from inside the electrical room cannot escape to the outside of the cooking appliance and flows back into the door through the exhaust hole. When this backflow occurs, cold air cannot properly flow into the inside of the door, making it difficult to cool the door smoothly.

Prior Document 1 (Korean Patent Publication No. 10-2015-0030016) discloses an oven.

As shown in FIGS. 29 and 30, the oven 1 disclosed in Prior Document 1 includes a casing 10 in which a cooking chamber 20 is provided, and a door 30 that opens and closes the open front of the cooking chamber 20. may include.

The cooking chamber 20 is a cooking space formed by a top plate 21, a bottom plate 22, both side plates 23, and a rear plate 24. Various parts constituting the oven 1 may be installed in the space between the outside of the cooking compartment 20 and the casing 10 (hereinafter referred to as the “electrical compartment”). A control panel 12 may be installed at the upper end of the casing 10 to control the operation of the oven 1.

A cooling fan 50 may be installed outside the top plate 21. The cooling fan 50 can introduce external air into the electrical equipment room through at least one opening installed on the rear panel 11 of the casing 10, etc., and then discharge the air introduced into the electrical equipment room back to the outside. .

A cooling passage 55 may be provided inside the battlefield. The cooling passage 55 forms a passage through which air sucked in by the cooling fan 50 flows toward the front of the oven 1.

A cooling discharge port 57 may be provided on the front side of the cooling passage 55. The air that has passed through the cooling passage 55 may be discharged to the upper part of the door 30 through the cooling discharge port 57. The cooling outlet 57 may be located rearward of the door 30.

A cooling guide 80 may be installed at the front end of the cooling discharge port 57. The cooling guide 80 may be provided in the form of a bent bracket to narrow the width of the cooling discharge port 57.

In the cooling discharge port 57 whose width is narrowed due to the cooling guide 80, a phenomenon in which the flow rate of air passing through the cooling discharge port 57 increases may occur. Accordingly, the air passing through the cooling discharge port 57 is discharged to the outside of the oven 1 at a high speed, while the pressure of the cooling discharge port 57 is lowered and the surrounding air gathers around the cooling discharge port 57. phenomenon may occur.

In this way, the air around the cooling outlet 57 gathers at the top of the door 30, thereby causing the air inside the door 30 to be discharged to the top of the door 30.

Prior Literature 1 states that, by inducing the discharge of air inside the door 30 induced in this way, the inflow of cold air into the inside of the door 30 is activated, and the inside of the door 30 of the air discharged through the cooling discharge port 57 is activated. It suggests the effect that backflow into the furnace can be suppressed.

However, Prior Document 1 has the following problems.

According to Prior Literature 1, the air passing through the cooling outlet 57 and the air discharged from the door 30 are discharged into a space located in front of the cooling outlet 57 and above the door 30.

That is, as the air discharged through the cooling discharge port 57 and the air discharged from inside the door 30 merge in one space, a vortex may be generated within the space. As vortices are generated in this way, the air that has passed through the cooling discharge port (57) and the air discharged from the door (30) may not be properly discharged to the outside of the oven (1), and the air in the space may not be discharged properly to the outside of the door (30). ) Internal reflux may occur.

In this case, it is difficult to properly cool the inside of the electrical equipment room and the inside of the door 30.

Additionally, in Prior Document 1, the cooling guide 80 also extends longitudinally along the lower part of the cooling discharge port 57, and the cooling guide 80 is fixed to the lower part of the cooling discharge port 57.

If the cooling outlet 57 is formed in a form divided into a plurality of pieces along the width direction of the oven 1, a plurality of cooling guides 80 to be fixed to the lower part of the cooling outlet 57 must also be provided.

In this case, a problem arises in that the assembly man-hours and number of parts required to install the cooling guide 80 are increased.

In addition, if the cooling discharge port 57 is provided in a continuous form along the width direction of the oven 1, that is, if only one long cooling discharge port 57 is formed in the oven 1, the strength of the front of the casing 1 increases accordingly. has no choice but to become weak.

On the other hand, when meat or food containing meat is heated and cooked using the above-mentioned sealed cooking device, oil such as fat or oil from the food floats inside the cooking chamber and adheres to the wall of the cooking chamber. It contaminates the inner wall of the kitchen.

The oil that adheres (adheres) to the wall of the cooking chamber in this way undergoes so-called polymerization (polymerization (reaction)) and sticks hard, making it difficult to clean (remove).

Among recently released cooking appliances, there are those equipped with a self-cleaning function that automatically removes contaminants such as oil as described above.

The self-cleaning function of cooking appliances is a function that automatically removes contaminants such as oil attached to the walls of the cooking chamber.

Self-cleaning in cooking appliances removes contaminants such as oil by burning them by heating the interior of the cooking chamber with a heat source such as a burner or heater to maintain the temperature inside the cooking chamber at a high temperature for a long time when contaminants such as oil adhere to the walls of the cooking chamber. This is mainly done using a thermal decomposition method called pyrolysis.

Prior document 1 also discloses a pyrolytic cleaning function that is the same or similar to this self-cleaning function. According to this, the control unit 38 of Prior Document 1 can perform a cleaning mode in which foreign substances are removed by thermal decomposition by increasing the temperature inside the cooking chamber 20. At this time, pyrolytic cleaning may be performed in the form of maintaining the internal temperature of the cooking chamber 20 at a high temperature for a long time using an electric heater 42 to burn and remove contaminants.

When the above-mentioned pyrolytic cleaning is performed, the inside of the cooking chamber 20 is maintained at a very high temperature. Therefore, to prevent safety accidents, the door of the cooking appliance must be tightly closed while the self-cleaning operation is in progress.

For this purpose, the oven 1 may be provided with a door locking device. The door lock device may be installed on the front of the oven 1 and may include a latch provided to lock the door 30 and a driving unit for operating the latch.

The driving unit may include a motor, and the driving unit and the latch may be connected by a link structure. The latch remains engaged with the door 30 while the door 30 must remain closed. When the door 30 no longer needs to remain closed, the latch may be released from the door 30.

The latch is installed on the front of the oven 1, rotates forward, and can protrude toward the front of the oven 1. This latch may rotate forward and protrude to be caught on the door 30, and may rotate backward and be separated from the door 30.

A locking groove may be provided at the top of the door 30, and the latch is inserted into the locking groove from the top of the locking groove and caught on the door 30, so that the door 30 can be locked by the door locking device.

The latch may be installed to be exposed to the front of the oven 1 so that the latch can protrude to the front of the oven 1 when necessary. Additionally, this latch may be placed higher than the door 30 so that it can enter and exit a locking groove provided at the top of the door 30.

In prior art document 1, if the latch is installed in the above position, the latch is positioned at the front of the oven 1 not only when the door 30 opens the cooking chamber 20 but also when the door 30 closes the cooking chamber 20. is exposed as

That is, the latch disposed above the door 30 is exposed to the front of the oven 1 through the gap between the door 30 and the control panel, which may deteriorate the aesthetics of the oven 1.

Additionally, Prior Document 2 (French Patent No. 2746903) discloses a cooking appliance.

The cooking appliance disclosed in prior art 2 may include a component 5 disposed on the outlet side of the duct 3, as shown in FIGS. 31 to 33.

The part 5 is installed on the door 2 and can separate the second airflow F2 flowing along the cooling passage formed by the duct 3 into the upper and lower sides. This component 5 can separate the second airflow F2 into an upper airflow Fa2 and a lower airflow F2b at the outlet side of the cooling passage.

Among the upper airflow (Fa2) and the lower airflow (F2b) separated in this way, the lower airflow (F2b) proceeds at a faster speed than the upper airflow (Fa2). The lower airflow (F2b) may join the first airflow (F1) rising inside the door 2 and then be discharged forward.

Prior Document 2 as described above has the following problems.

According to prior literature 2, as the lower airflow (F2b) joins the first airflow (F1), flow resistance increases in the space between the upper part of the door (2) and the part (5).

As the flow resistance increases in this way, the amount of air discharged forward of the first air stream (F1) and the second air stream (F2) decreases, which causes a problem in that the cooling performance of the cooking appliance deteriorates.

Additionally, if the flow resistance increases as described above, a problem of increased noise around the door (2) also occurs.

Also, according to prior art document 2, the first airflow (F1) and the lower airflow (F2b) are discharged through the lower side of the part (5), and these airflows are discharged forward at a position very close to the door (2).

In this process, the hot discharge flow may come into contact with the glass panel 2a of the door 2, causing a problem of increasing the temperature of the front of the door 2.

In addition, according to prior art document 2, the path through which the lower airflow F2b flows through the lower part of the part 5 and the outlet at the top of the door 2 are communicated. Accordingly, a phenomenon may occur in which part of the lower airflow (F2b) flows into the inside of the door (2) or part of the first airflow (F) flows back into the door (2).

When this phenomenon occurs, the temperature of the door 2 increases, which reduces product reliability and increases the risk of burns to the user.

Additionally, according to Prior Literature 2, the component 5 is exposed to an environment where it is in contact with hot discharge flow for a long time when the cooking device is in operation. Since these parts 5 are installed on the door 2, they move toward the user along the door 2 when the door 2 is opened.

Accordingly, when the door 2 is opened, the risk of burns to the user increases due to the high-temperature components 5.

The air inlet hole 132 may form a passage connecting the space between the upper surface of the cavity 110 and the upper panel 131 and the cooling passage 255. The air heated between the upper surface of the cavity 110 and the upper panel 131 due to the heated cavity 110 flows into the cooling passage 255 through the air inlet hole 132 and then flows through the exhaust port 122. It can be discharged to the outside of the cooking appliance.

The temperature of the space between the upper surface of the cavity 110 and the upper panel 131 has a significant influence on the temperature of the electrical equipment compartment 250. Therefore, if the temperature of the space between the upper surface of the cavity 110 and the upper panel 131 can be lowered, the temperature of the electrical equipment room 250 can also be effectively lowered.

Taking this into consideration, in this embodiment, the heat between the upper surface of the cavity 110 and the upper panel 131 is discharged to the outside through the air inlet hole 132, thereby cooling the electrical equipment compartment 250. Let’s make this happen more effectively.

Hereinafter, the front-to-back length of the air guide 300 will be referred to as “length,” the lateral length of the air guide 300 will be referred to as “width,” and the vertical length of the air guide 300 will be referred to as “thickness.” .

According to this embodiment, the air guide 300 may be formed in a frame shape that is longer in width compared to the length and thickness and thinner than the length and width.

The vertical length, or thickness, of the air guide 300 may be less than or equal to the vertical length of the front space (S). This air guide 300 can be accommodated inside the front space (S). In addition, the air discharged from the exhaust port 122 or the door exhaust port 152 flows forward inside the front space (S) and can pass through the air guide 300, and passes through the air guide 300 to the outside of the cooking appliance. can be discharged as

The air guide 300 disposed in the front space (S) as described above can divide at least a portion of the front space (S) into a first space (S1) and a second space (S2).

The lateral length, that is, the width, of the air guide 300 may be a length corresponding to the lateral length of the front space (S). For example, the width of the air guide 300 may correspond to at least one of the lateral length of the control panel 200 and the lateral length of the door 150.

In this embodiment, the first space (S1) is the space between the control panel 120 and the air guide 300, and the second space (S2) is the space between the air guide 300 and the door 150. It can be defined as

More specifically, the first space (S1) is the space between the first guide part 310 and the control panel 120, which will be described later, and the second space (S2) is the space between the first guide part 310 and the control panel 120, which will be described later. It may be defined as the space between the doors 150. The first space (S1) and the second space (S2) may be partitioned upward and downward by the first guide part 310.

The air guide 300 is disposed in the front space (S), but may be disposed in a front-biased area of the front space (S). This air guide 300 can divide the front area of the front space (S) into a first space (S1) and a second space (S2).

Additionally, the air guide 300 may be placed on the lower side of the control panel 200 and coupled to the control panel 200. For this purpose, cover protrusions 210 and 220 may be provided between the control panel 200 and the air guide 300.

The cover protrusions 210 and 220 may be formed to protrude downward from the bottom of the control panel 200. The air guide 300 may be coupled to the cover protrusions 210 and 220 at a position spaced apart from the bottom of the control panel 200. This air guide 300 may be arranged on the lower side of the control panel 200 to be spaced apart from the control panel 200 by a predetermined distance.

According to this embodiment, a plurality of cover protrusions 210 and 220 may be arranged to be spaced apart from each other at a predetermined distance in the lateral direction. And the air guide 300 can be stably fixed to the lower side of the control panel 200 by being coupled to the plurality of cover protrusions 210 and 220, respectively.

Referring to Figures 3 and 13 to 15, the air guide 300 may include a first guide part 310 and a second guide part 320.

The first guide part 310 and the second guide part 320 are parts that occupy most of the area of the air guide 300 and can form most of the exterior of the air guide 300. According to this embodiment, the cover protrusions 210 and 220 may be coupled to at least one of the first guide part 310 and the second guide part 320.

The first guide portion 310 is a portion disposed on the front side of the air guide 300, and may be disposed on the front side of the second guide portion 320. This first guide portion 310 is a control panel It is disposed between 120 and the door 150 to divide the space between the control panel 120 and the door 150 upward and downward.

This first guide unit 310 can divide the space between the control panel 120 and the door 150 into an upper first space (S1) and a lower second space (S2).

The second guide portion 320 is a portion disposed on the rear side of the air guide 300 and may be disposed rearward than the first guide portion 310. This second guide part 320 may be connected to the first guide part 310 at the rear side of the first guide part 310. The second guide part 320 prepared in this way may serve to block the second space S2.

The second guide part 320 may be provided to block the second space S2 between the first guide part 310 and the door exhaust port 152. This second guide part 320 may extend backward from the first guide part 310 at a downward angle.

As an example, the first guide part 310 may be formed in a planar shape parallel to the bottom surface of the control panel 120 or the top surface of the door 150. At this time, the first guide part 310 may be formed in a shape including a plane perpendicular to the vertical axis.

The second guide part 320 may be provided to be connected to the first guide part 310 in the front-to-back direction. This second guide part 320 may be formed to extend rearward from the rear end of the first guide part 310.

As an example, the second guide part 320 may be formed in the shape of an inclined surface extending rearward from the rear end of the first guide part 310. At this time, the second guide portion 320 may be formed in the shape of an inclined surface extending downward toward the rear.

The second guide part 320 formed in this way blocks the second space (S2) between the first guide part 310 and the door exhaust port 152, thereby allowing air to flow forward through the second space (S2). Movement can be blocked. A detailed explanation of this will be provided later.

As another example, the air guide 300a may be provided in a form including a first guide part 310a and a second guide part 320 connected in a straight line (see FIG. 16).

In this case, the first guide part 310a may be formed in the shape of an inclined surface extending straight ahead of the second guide part 320.

The air guide 300a formed in this shape allows the area covered by the air guide 300a in the front gap to expand in the vertical direction, while also allowing smooth exhaust to the front of the cooking appliance through the front space. You can.

As another example, the air guide 300b may be provided in a form including a second guide portion 320b formed in a curved shape (see FIG. 17).

In this case, the second guide portion 320a may be formed to be inclined downward toward the rear, but its upper surface may be formed in a convex curved shape.

The air guide 300b formed in this shape allows the flow of air toward the second guide portion 320b to be smoothly guided toward the front along the curved surface of the second guide portion 320b.

This air guide (300b) can reduce the resistance generated when air discharged through the exhaust port 122 comes into contact with the second guide part (320b).

By using this air guide (300b), exhaust air to the front of the cooking appliance through the front space can be achieved more smoothly.

As another example, the air guide 300c may be provided in a form including a first guide part 320c and a second guide part 320b connected by a single curve (see FIG. 18).

In this case, the first guide part 320c extends forward of the second guide part 320b and may be formed in a curved shape that smoothly connects with the second guide part 320b. At this time, the first guide part 320c, like the second guide part 320b, may be formed in a curved shape with a convex upper surface.

The air guide 300c formed in this shape has a smoother appearance and can induce smooth exhaust compared to the air guide 300b shown in FIG. 17.

Meanwhile, the air guide 300 may further include a fastening protrusion 330, as shown in FIGS. 3 and 10 to 15. The fastening protrusion 330 may be provided for coupling between the air guide 300 and the control panel 120.

In this embodiment, the fastening protrusion 330 may be disposed on the side of the second guide portion 320, which is located relatively further rearward, among the first guide portion 310 and the second guide portion 320. These fastening protrusions 330 may be formed to protrude from the second guide portion 320 in the vertical direction.

Each fastening protrusion 330 may be coupled to the cover protrusions 210 and 220. As an example, the plurality of cover protrusions 210 and 220 and the fastening protrusions 330 may be arranged to face each other in the vertical direction. As the respective cover protrusions 210 and 220 and the fastening protrusions 330 facing each other in the vertical direction are coupled in this way, coupling between the control panel 120 and the air guide 300 can be achieved.

In addition, the air guide 300 may further include an extension portion 315. The extension portion 315 may be disposed on both sides of the first guide portion 310 in the lateral direction. This extension part 315 may be formed to protrude laterally from the first guide part 310.

The extension portion 315 is not a portion coupled to the cover protrusions 210 and 220. Accordingly, the length of the extension portion 315 may be set shorter than the total length of the first guide portion 310 and the air guide 300.

The extension portion 315 is formed in a form in which the length of the extension portion 315 is shorter than the total length of the first guide portion 310 air guide 300, thereby reducing the overall size and weight of the air guide 300. It may not increase.

The extension portion 315 may be disposed biased toward the front side of the air guide 300. Preferably, the first guide part 310 and the extension part 315 are laterally connected so that the front end of the extension part 315 and the front end of the first guide part 310 are disposed on the same line. You can.

In this embodiment, the extension part 315 is illustrated as protruding from the first guide part 310 with the same length as the first guide part 310.

Accordingly, although the length of the extension part 315 of the first guide part 310 is set shorter than the total length of the air guide 300, the appearance of the air guide 300 seen from the front is formed in a smoothly continuous form. It becomes possible.

In addition, the extension portion 315 may be disposed in front of the protruding surface portion 123, as shown in FIG. 7 . As described above, the protruding surface portion 123 is formed to protrude forward from the lateral end of the front panel 120.

The extension portion 315 disposed in front of the protruding surface portion 123 is formed to have a shorter length than the first guide portion 310 as described above and is disposed biased toward the front side on the air guide 300, so that the protruding surface portion ( 123) can be avoided.

That is, the extension portion 315 formed in the above shape has the effect of maintaining the aesthetics of the air guide 300 visible from the front while avoiding interference with the protruding surface portion 123, and the size and weight of the air guide 300. It can also provide the effect of preventing this from increasing unnecessarily.

[Air guide arrangement structure considering the front appearance of the cooking appliance]

FIG. 19 is a front view showing a portion of the front of the cooking appliance with the air guide removed, and FIG. 20 is an enlarged view of a portion of the front of the cooking appliance shown in FIG. 19. Additionally, FIG. 21 is a front view showing a portion of the front of the cooking appliance according to an embodiment of the present invention, and FIG. 22 is an enlarged view showing a portion of the front of the cooking appliance shown in FIG. 21.

Referring to FIGS. 19 and 20, when the air guide is excluded from the cooking appliance, various airflows of the cooking appliance are exposed through the gap between the control panel 200 and the door 150 (hereinafter referred to as the “front gap”). Parts may be exposed to the front of the cooking appliance.

As an example, a portion of the front panel 120 may be exposed to the front of the cooking appliance through the front gap. Specifically, a plurality of exhaust ports 122 provided in the control panel 200 may be exposed to the front of the cooking appliance through the front gap. Additionally, the partition walls 121 disposed between the exhaust ports 122 may be exposed to the front of the cooking appliance through the front gap.

In addition, among various electrical components disposed in the electrical equipment compartment 250, a portion disposed behind the exhaust port 122 may be exposed to the front of the cooking appliance through the front gap.

Additionally, at least a portion of the door lock may be exposed to the front of the cooking appliance through the front gap. For example, most of the latch 140 may be exposed to the front of the cooking appliance through the front gap. Additionally, a portion of the driving unit 145 along with the latch 140 may be exposed to the front of the cooking appliance through the front gap.

When the above items are exposed to the front of the cooking appliance, they may have a negative impact on the front appearance of the cooking appliance. That is, the shapes formed on the front panel 120, such as the exhaust port 122 and the partition wall 121, the complex-shaped structures such as the latch 140, and the electrical components exposed through the exhaust port 122, add to the aesthetics of the front of the cooking appliance. It can be a damaging factor.

In order to reduce the impact they have on the front aesthetics of the cooking appliance, in this embodiment, as shown in FIGS. 21 and 22, an air guide 300 may be provided in the cooking appliance.

The air guide 300 may be placed in the front gap. The air guide 300 is disposed between the control panel 200 and the door 150, and is provided to cover parts of the front panel 120, latch 140, and electrical components from the front.

This air guide 300 covers a portion of the front gap between the control panel 200 and the door 150, and thus the front panel 120 and the latch 140, which were exposed to the front of the cooking appliance through the front gap. ), some parts of the electrical components, etc. may be obscured by the air guide 300.

As the thickness of the air guide 300 increases, the area covered by the air guide 300 may expand. As the area covered by the air guide 300 is expanded, the aesthetics of the front of the cooking appliance may be improved, but exhaustion to the front of the cooking appliance through the front space (S; see FIG. 3) becomes more difficult.

Conversely, as the thickness of the air guide 300 becomes thinner, the area covered by the air guide 300 may decrease. As the area covered by the air guide 300 decreases, the effect of improving the front aesthetics of the cooking appliance decreases, but instead, exhaust to the front of the cooking appliance through the front space S can be achieved more smoothly.

Considering this, it is preferable that the thickness of the air guide 300 is set to the thickest thickness within a range that ensures smooth exhaustion to the front of the cooking appliance through the front space (S).

When the thickness of the air guide 300 is set to satisfy these conditions, the exhaust efficiency through the front gap can be maintained at a certain level or higher while effectively improving the front aesthetics of the cooking appliance.

According to this embodiment, some of the areas exposed to the front of the cooking appliance through the front gap are covered by the air guide 300, thereby improving the aesthetics of the front of the cooking appliance.

As an example, the air guide 300 may be placed in the front gap, and the first guide part 310 may be positioned in the vertical center of the front gap. That is, the air guide 300 is disposed between the door 150 that closes the galley and the control panel 200, and the vertical distance between the first guide part 310 and the control panel 200 and the first guide part ( It may be placed at a position where the vertical distance between 310) and the door 150 is set to be the same (hereinafter referred to as the “center position”).

Accordingly, the air guide 300 can form a structure that allows the first guide part 310 to cover the front gap at the vertical center of the front gap, that is, at the central position.

This air guide 300 allows the upper area of the front gap and the lower area of the front gap to be symmetrical around the first guide part 310, thereby making the front shape of the cooking appliance appear more stable. This can contribute to improving the overall aesthetics of the cooking appliance.

Additionally, the air guide 300 in this embodiment can cover the lower area of the front gap through the second guide part 320 disposed on the rear side of the first guide part 310. At this time, since the second guide part 320 is disposed on the rear side of the first guide part 310, it is not as noticeable as the first guide part 310 when viewed from the front.

That is, the second guide part 320 can cover the lower area of the front gap in a less conspicuous position compared to the first guide part 310.

The air guide 300 having this second guide part 320 covers the front gap so that the upper area of the front gap and the lower area of the front gap are symmetrical around the first guide unit 310, and The lower area of the front gap can be further covered by using the second guide part 320, which is less noticeable than the first guide part 310.

The air guide 300 of this embodiment can effectively improve the front aesthetics of the cooking appliance while making the front shape of the cooking appliance appear more stable.

Meanwhile, as described above, the air guide 300 may be coupled to the control panel 200 by the cover protrusions 210 and 220.

As an example, the cover protrusions 210 and 220 may include an outer cover protrusion 210.

The outer cover protrusion 210 may be provided in a form that protrudes downward from the bottom of the control panel 200. This outer cover protrusion 210 may be coupled to the air guide 300 at the lower part of the control panel 200. By coupling between the outer cover protrusion 210 and the air guide 300, the air guide 300 can be coupled to the control panel 200 while being spaced a predetermined distance from the bottom of the control panel 200.

Preferably, when the outer cover protrusion 210 is coupled to the air guide 300, the air guide 300 may be disposed at a central position.

The outer cover protrusion 210 may be disposed in a position to cover at least a portion of the latch 140 from the front side. For example, the outer cover protrusion 210 protrudes downward from the bottom of the control panel 200, and may protrude from the vertical upper side of the latch 140.

At least a portion of the latch 140 is covered by the outer cover protrusion 210 arranged in this way. Accordingly, when viewed from the front, at least a portion of the latch 140 is obscured by the outer cover protrusion 210 and is not visible.

As an example, the outer cover protrusion 210 may be formed to protrude from the bottom of the control panel 200 to the central position. Additionally, the width of the outer cover protrusion 210 may be set to be greater than or equal to the width of the latch 140. This outer cover protrusion 210 may cover the upper half of the latch 140 exposed through the front gap from the front. The lower half of the latch 140 may be exposed to the lower side of the air guide 300.

According to this embodiment, the side shape of the latch 140 may be set to approximately an “L” shape. This latch 140 may be formed so that its upper end protrudes forward. Therefore, when viewed from the front, the upper half of the latch 140 has a more complicated shape than the lower half of the latch 140.

The outer cover protrusion 210 is formed to protrude from the control panel 200 by the length necessary to be coupled with the air guide 300, while protruding from the control panel 200 by the length necessary to cover the upper half of the latch 140. can be formed.

That is, the outer cover protrusion 210 only protrudes long enough to cover the upper half of the latch 140 while fixing the air guide 300 in the central position, but does not protrude longer.

If the outer cover protrusion 210 protrudes longer, the outer cover protrusion 210 may cover more of the latch 140, but the coupling structure of the outer cover protrusion 210 and the air guide 300 is complicated. Problems may arise where the combination itself becomes difficult. Additionally, unnecessarily protruding structures may cause the problem of deteriorating the overall aesthetics of the cooking appliance.

Considering this, in this embodiment, the outer cover protrusion 210 does not protrude unnecessarily long, but protrudes long enough to cover the upper half of the latch 140 while fixing the air guide 300 in the central position.

This outer cover protrusion 210 preferentially covers the upper half of the latch 140, which is a part that can greatly affect the front aesthetics of the cooking appliance, and also arranges the air guide 300 in the central position. , can contribute to effectively improving the overall aesthetics of cooking appliances.

As another example, the air guide 300 may be disposed in the front gap, but may be disposed in a position more inclined downward from the vertical center of the front gap.

Considering that the user's eye level is generally higher than the height of the air guide 300 placed between the door 150 and the control panel 200, the air guide 300 must be placed in the above position to allow the user to use air. The guide 300 can be better identified.

In addition, the aesthetics provided by the air guide 300 can be expressed more effectively when the air guide 300 is placed in a position where the air guide 300 can be clearly seen from the outside of the cooking appliance.

In other words, by arranging the air guide 300 in a position more inclined toward the bottom from the vertical center of the front gap, aesthetics can be effectively created.

In addition, when the air guide 300 is disposed at the above position, the vertical length of the cover projections 210 and 220, especially the outer cover projection 210, becomes longer.

When the length of the outer cover protrusion 200 is increased in this way, the outer cover protrusion 210 can cover the latch 140 and cover a wider area than the upper half of the latch 140. In this way, more of the latch 140 is covered by the outer cover protrusion 210, so that the front aesthetics of the cooking appliance can be more effectively improved.

Meanwhile, in this embodiment, the latch 140 is illustrated as being disposed on one side of the main body 100 in the lateral direction. For example, in a cooking appliance, one latch 140 may be disposed at a position biased toward one side of the main body 100. At this time, the latch 140 may be disposed in a position that is more biased to one side of the main body 100 in the lateral direction than the exhaust port 122.

According to this embodiment, a pair of outer cover protrusions 210 may be disposed between the control panel 200 and the air guide 300. The pair of outer cover protrusions 210 may be arranged symmetrically about the lateral center of the cooking compartment, that is, about the lateral center of the main body 100. Alternatively, the pair of outer cover protrusions 210 may be expressed as being symmetrically disposed about the lateral center of the control panel 200.

One of the pair of outer cover protrusions 210 may be disposed in front of the latch 140 and cover the upper half of the latch 140 from the front. The other one of the pair of outer cover protrusions 210 is not disposed in front of the latch 140.

However, by arranging the pair of outer cover protrusions 210 symmetrically as described above, the shapes of the cover protrusions 210 and 220 and the air guide 300 exposed through the front gap can appear more balanced.

The cover protrusions 210 and 220 may include an inner cover protrusion 220.

The inner cover protrusion 220 may be provided in a form that protrudes downward from the bottom of the control panel 200. This inner cover protrusion 220 may be coupled to the air guide 300 at the lower part of the control panel 200. By coupling between the inner cover protrusion 220 and the air guide 300, the air guide 300 can be coupled to the control panel 200 while being spaced a predetermined distance from the bottom of the control panel 200.

Preferably, when the inner cover protrusion 220 is coupled to the air guide 300, the air guide 300 may be placed at a central position.

The inner cover protrusion 220 may be disposed in a position where at least a portion of the inner cover protrusion 220 can cover at least a portion of the partition wall 121 from the front side. For example, the inner cover protrusion 220 protrudes downward from the bottom of the control panel 200, and may protrude from the vertical upper side of the partition wall 121.

At least a portion of the partition wall 121 is covered by the inner cover protrusion 220 arranged in this way. Accordingly, when viewed from the front, at least a portion of the partition wall 121 is obscured by the inner cover protrusion 220 and is not visible.

The inner cover protrusion 220 arranged as described above may be disposed between a pair of outer cover protrusions 210. For example, among the plurality of cover protrusions 210 and 220 arranged in the lateral direction, the outer cover protrusion 210 may be disposed on the outermost side in the lateral direction, and the inner cover protrusion 220 may be disposed between them.

By the inner cover protrusion 220 and the outer cover protrusion 210 provided in this way, the air guide 300 is coupled to the cover protrusions 210 and 220 at multiple points in the lateral direction and is stably fixed to the lower part of the control panel 200. You can.

That is, the inner cover protrusion 220 can contribute to stably fixing the air guide 300 by increasing the coupling point between the control panel 200 and the air guide 300.

In addition, the inner cover protrusion 220 is disposed in a position to cover the partition wall 121 from the front, thereby preventing the number of vertical structures exposed through the front gap from increasing.

That is, the inner cover protrusion 220 may be arranged in such a way that the inner cover protrusion 220 covers the partition wall 121, which is a vertical structure that is exposed anyway through the front gap. As a result, it may appear that the number of longitudinal structures exposed through the anterior gap has not increased.

As a result, it is possible to effectively prevent the front aesthetics of the cooking appliance from being deteriorated due to the vertical structure exposed through the front gap.

Additionally, the inner cover protrusion 220 arranged as described above can be placed in a position avoiding the exhaust port 122. The exhaust port 122 forms a passage necessary for air from the battlefield room 250 (see FIG. 3) to be discharged into the front space S.

The air introduced into the electrical equipment room 250 by the fan 260 (see FIG. 3) exchanges heat within the electrical equipment room 250 and can cool electrical components, etc. The air heat-exchanged inside the electrical equipment compartment 250 may be discharged at a high temperature into the front space S through the exhaust port 122.

Assuming that the inner cover protrusion 220 is made of a plastic material, if the inner cover protrusion 220 is constantly exposed to high temperature air discharged through the exhaust port 122, thermal deformation of the inner cover protrusion 220 occurs. The risk of becoming infected may increase.

For example, if the inner cover protrusion 220 is disposed in front of the exhaust port 122 rather than in front of the partition wall 121, thermal deformation of the inner cover protrusion 220 may occur due to the high temperature air discharged through the exhaust port 122. It can happen.

Considering this, in this embodiment, the inner cover protrusion 220 is disposed at a position avoiding the exhaust port 122, that is, in front of the partition wall 121 rather than in front of the exhaust port 122.

As a result, thermal deformation of the inner cover protrusion 220 can be effectively prevented, and air can be discharged through the exhaust port 122 smoothly without being hindered by the inner cover protrusion 220.

That is, the inner cover protrusion 220 of the present embodiment is disposed in a position to cover the exhaust port 122 from the front, so there is a risk of thermal deformation of the inner cover protrusion 220 without impeding the discharge of air through the exhaust port 122. It can be placed in a position that lowers and improves the front aesthetics of the cooking appliance.

In summary, the effects provided by the air guide 300 arranged as above and the cover protrusions 210 and 220 for fixing it are as follows.

First, the aesthetics of the front of the cooking appliance can be improved by covering some of the structures exposed through the front gap by the air guide 300, which laterally crosses the front gap and provides a structure that covers the front gap.

The air guide 300 covers part of other structures at the rear and focuses the gaze looking at the front gap on the air guide 300, creating an optical illusion that only the air guide 300 exists in the front gap. ensure that it is provided.

In addition, the air guide 300 forms a structure that covers the front gap at the center of the front gap, so that the upper area of the front gap and the lower area of the front gap are symmetrical, and the front shape of the cooking appliance is more stable. It can be displayed as .

Through this, the air guide 300 can contribute to effectively improving the front aesthetics of the cooking appliance.

Second, by covering at least a portion of a large and complex structure, such as the latch 140, by the outer cover protrusion 210, the front aesthetics of the cooking appliance can be more effectively improved.

According to this embodiment, the upper half of the latch 140, which is a part that can greatly affect the front appearance of the cooking appliance, may be covered by the outer cover protrusion 210 provided for fixing the air guide 300. .

That is, the arrangement position of the outer cover protrusion 210 provided for fixing the air guide 300 is appropriately set in front of the latch 140, thereby stably fixing the air guide 300 and improving the front aesthetics of the cooking appliance. It can be accomplished.

Third, the inner cover protrusion 220 is disposed in a position to cover the partition wall 121 dividing the exhaust port 122 between the exhaust port 122 from the front, so that the inner cover protrusion 220 does not interfere with the discharge of air through the exhaust port 122. It can provide the effect of lowering the risk of thermal deformation of the cover protrusion 220 and the effect of improving the front aesthetics of the cooking appliance.

[Coupling structure between control panel and air guide]

Figure 23 is a cross-sectional perspective view showing the coupling structure between the air guide and the control panel, and Figure 24 is a cross-sectional exploded perspective view showing the separated state of the air guide and control panel shown in Figure 23.

21 to 24, cover protrusions 210 and 220 may be included in the front panel 120. As an example, the cover protrusions 210 and 220 may be formed integrally with the front panel 120. More specifically, the cover protrusions 210 and 220 may be formed integrally with the bottom of the front panel 120.

In this embodiment, the bottom of the front panel 120 and the cover protrusions 210 and 220 are illustrated as being made of plastic material. Since the cover projections 210 and 220 are made of plastic and are formed integrally with the bottom of the front panel 120, not only can the cost required for adding the cover projections 210 and 220 be reduced, but the cover projections 210 and 220 are made of metal. Compared to the case in which they are formed, the weight of the cover protrusions 210 and 220 can be significantly reduced.

The air guide 300 may be made of a metal material. As an example, the air guide 300 may be made of a metal material that has excellent heat resistance and a metal-specific luster. This air guide 300 is not easily deformed by high temperature heat, is not easily damaged by impact, and can contribute to improving the aesthetics of the cooking appliance through metallic luster.

Considering that the air guide 300 is placed in a path where high-temperature air is discharged, that it is placed in a prominent position on the front of the cooking appliance, and that it is placed in a location where frequent contact with the user may occur, , In this embodiment, the air guide 300 is made of a metal material.

The cover protrusions 210 and 220 may be combined with the fastening protrusions 330. A hollow is formed in each of the cover protrusions 210 and 220, and a fastening hole in communication with the fastening protrusion 330 may be formed to penetrate in the vertical direction. These cover projections 210 and 220 and the fastening projection 330 may be coupled by a fastening member 305 such as a screw.

[Air guide arrangement structure considering exhaust flow]

FIG. 25 is a cross-sectional view showing the air flow inside the cooking appliance according to an embodiment of the present invention, FIG. 26 is an enlarged view showing a portion of the cooking appliance shown in FIG. 25, and FIG. 27 is an enlarged view of a portion of the cooking appliance shown in FIG. 26. This is an enlarged view of a portion of the illustrated cooking appliance.

Referring to FIGS. 25 to 28 , by operating the fan 260, external air may be introduced into the electrical equipment compartment 250 from the rear side of the cooking appliance. In this way, the air introduced into the electrical equipment room 250 can move forward inside the electrical equipment room 250 and cool the electrical components inside the electrical equipment room 250.

To be more specific, external air may flow into the inside of the cooking appliance through the lower part of the main body 100. The outside air flowing in through the lower part of the main body 100 passes through the rear space of the cooking appliance where the convection unit 160, etc. is disposed, and various parts disposed in the rear space of the cooking appliance, such as the convection unit 160. ) can be cooled.

In this way, the air that passes through the rear space of the cooking appliance and moves upward can move toward the electrical appliance room 250 through the space covered by the electrical appliance cover 133 between the rear space of the cooking appliance and the electrical appliance room 250. there is.

Air moving inside the electrical equipment compartment 250 may be sucked in by the fan 260 and flow into the cooling passage 255. The air flowing into the cooling passage 255 moves forward inside the cooling passage 255 and can cool the electrical components inside the electrical equipment compartment 250.

As described above, the air moving forward inside the electrical equipment compartment 250 may be discharged through the exhaust port 122 to the front of the electrical equipment compartment 250, that is, to the front space (S).

Additionally, the air inside the door 150 heated by the heat transferred from the cooking chamber 130 during the cooking process may be discharged to the outside of the door 150 through the door exhaust port 152 provided at the top of the door 150.

As the hot air inside the door 150 is discharged, the outside air at the front lower side of the cooking appliance may flow into the inside of the door 150 through the air flow hole provided at the bottom of the door 150 and rise. In this process, the heated door 150 may be cooled by the heat transferred from the cooking chamber 130 to the door 150.

Additionally, the air that cools the door 150 and rises inside the door 150 may be discharged into the front space (S) through the door exhaust port 152. That is, the air discharged through the exhaust port 122 and the air discharged through the door exhaust port 152 may join in the front space S and be discharged to the front of the cooking appliance.

According to this embodiment, the front space (S) is a space surrounded by the door 150, the front panel 120, and the control panel 200, and the air guide 300 can be placed in this front space (S). .

The exhaust port 122 may communicate with the front space (S) at the rear side of the front space (S), and the door exhaust port 152 may communicate with the front space (S) at the lower side of the front space (S). And the front space (S) may be open toward the front of the cooking appliance.

The door exhaust port 152 may be disposed between the air guide 300 and the front panel 120. Specifically, the door exhaust port 152 may be disposed in front of the exhaust port 122. That is, in the front-to-back direction, the door exhaust port 152 may be disposed between the air guide 300 and the exhaust port 122.

Additionally, the door exhaust port 152 may be disposed below the air guide 300 and the exhaust port 122. In addition, the door exhaust port 152 may be provided at the top of the door 150, but may be provided on the latter half (150b).

Accordingly, the door exhaust port 152 is disposed in a rearward position on the door 150, and may be disposed on the lower side rather than the top of the door 150 formed by the front half 150a.

Looking at the arrangement relationship between the exhaust port 122, the door exhaust port 152, and the air guide 300, the door exhaust port 152 is placed at a position on the door 150 that is closest to the exhaust port 122 in the front and rear directions. .

If the door exhaust port 152 is disposed in the front half (150a) rather than the rear half (150b) of the door 150, hot air discharged through the exhaust port 122 flows into the inside of the door 150 through the door exhaust port 152. The likelihood of reflux increases.

The air discharged through the exhaust port 122 gradually spreads in the front space (S) and moves forward in the front space (S). That is, the air discharged through the exhaust port 122 spreads not only in the left and right directions but also in the up and down directions within the front space (S) and moves forward.

Therefore, the closer the door exhaust port 152 is located to the front within the front space S, the more likely it is that the air discharged through the exhaust port 122 will flow into the door exhaust port 152. In this way, if the hot air discharged through the exhaust port 122 flows back into the door 150 through the door exhaust port 152, the door 150 cannot be cooled smoothly and flows into the front space (S). It becomes difficult for the heat to be discharged smoothly to the outside of the cooking appliance.

Taking this into consideration, in this embodiment, the door exhaust port 152 is disposed in the latter half (150b) of the door 150, and is thus located at a position on the door 150 that is closest to the exhaust port 122 in the front and rear directions. A door exhaust port 152 may be disposed.

As a result, the door exhaust port 152 can be placed in a position that can deviate from the flow area of the air discharged through the exhaust port 122 as much as possible among the selectable forward and backward positions within the door 150.

Additionally, according to this embodiment, the door exhaust port 152 is disposed in the rear half 150b, so that it can be disposed lower than the uppermost end of the door 150 formed by the front half 150a. That is, the door exhaust port 152 may be disposed further downward from the flow area of air discharged through the exhaust port 122.

As a result, the door exhaust port 152 can be placed in a position that can deviate from the flow area of the air discharged through the exhaust port 122 as much as possible. The door exhaust port 152 arranged in this way can contribute to effectively suppressing the phenomenon of hot air discharged into the front space S flowing back into the door 150.

Additionally, the door exhaust port 152 may not be disposed on the vertical lower side of the air guide 300, but may be disposed rearward than the air guide 300. Accordingly, the flow of air discharged from the door exhaust port 152 can flow smoothly toward the front space S without being interrupted by the air guide 300.

According to this embodiment, the door exhaust port 152 may be disposed between the air guide 300 and the front panel 120. That is, the air guide 300 may be disposed in front of the exhaust port 122 and the door exhaust port 152. This air guide 300 may be placed at a position biased toward the front within the front space (S).

The air guide 300 arranged in this way can guide the flow of air discharged from the exhaust port 122 and the door exhaust port 152 to the front space (S) from the front side of the front space (S).

For example, the air discharged from the exhaust port 122 and the door exhaust port 152 into the front space (S) may merge in the front space (S) and be discharged to the front of the cooking appliance. The air guide 300 may be disposed in the flow path (hereinafter referred to as “exhaust path”) of air discharged from the front space S to the front of the cooking appliance.

The air guide 300 arranged in this way may be provided in the form of a frame that is longer in width compared to the length and thickness and thinner than the length and width.

This air guide 300 can divide the space between the control panel 120 and the door 150 into a first space (S1) and a second space (S2).

The first guide portion 310 of the air guide 300 is disposed at the center of the front space S in the vertical direction. And the second guide part 320 disposed on the rear side of the first guide part 310 blocks the second space S2 at the lower side of the first guide part 310.

Accordingly, the air flowing into the front space (S) through the exhaust port 122 cannot move forward through the second space (S2) blocked by the second guide part 320, and moves into the second space (S2). ) flows forward only through the first space (S1) located on the upper side. Accordingly, the air discharged from the exhaust port 122 may be discharged to the front of the cooking appliance through a space biased toward the upper side of the front space S.

Additionally, the air discharged from the door exhaust port 152 cannot move forward through the second space (S2), but only flows forward through the first space (S1). Accordingly, the air discharged from the door exhaust port 152 may move to a position higher than the second space S2 and then be discharged to the front of the cooking appliance through a space biased toward the upper side of the front space S2.

According to this, air flowing into the front space (S) through the exhaust port 122 and the door exhaust port 152 may merge in the front space (S) and move forward through the first space (S1).

At this time, the air that joins in the front space (S) after being discharged from the exhaust port 122 and the door exhaust port 152 as described above is not separated into several streams by the air guide 300, and is moved to the first space (S1). ) and can be discharged to the front of the cooking appliance.

Additionally, the air forming the above flow may be discharged to the front of the cooking appliance through a space biased toward the upper side of the front space (S).

When the flow discharged forward from the front space (S) is separated into upper and lower sides by the air guide 300, the air flow passing through the upper side of the air guide 300 and the air flowing through the lower side of the air guide 300 There may be a difference in speed between the air flows.

If a speed difference occurs between the two flows of separated air, there is a possibility that a vortex may be generated in front of the air guide 300.

When a vortex is generated in this way, the air flowing into the front space (S) may not be properly discharged to the outside of the cooking appliance, or the air in the front space (S) may be inside the door 150 through the door exhaust port 152. A backflow phenomenon may occur.

Considering this, in this embodiment, air can only flow through one space formed on the upper side of the air guide 300, that is, the first space (S1).

To this end, the air guide 300 of this embodiment blocks the second space S2 through the second guide part 320, thereby blocking the forward movement of air through the second space S2.

Accordingly, in the front space (S), forward movement of air can be achieved only through a single flow through the first space (S1).

In this way, when air can move forward only through a single flow through the first space (S1), the possibility of vortices being generated in front of the air guide 300 and the cooking appliance can be significantly reduced.

That is, the air guide 300, which is provided to block the space on the lower side of the air guide 300, allows the air flow flowing through the exhaust passage to be discharged forward without branching, thereby protecting the front of the cooking appliance. It is possible to ensure that the exhaust is discharged smoothly.

In addition, the air guide 300 can guide the flow of air so that exhaust occurs through the first space (S1), which is a space biased toward the upper side of the front space (S). This air guide 300 can guide the air flow so that the gap between the exhaust flow and the door 150 increases.

Accordingly, exhaust is discharged toward the front of the cooking appliance from the side farthest from the door 150 in the front space (S), so the distance between the hot air discharged to the front of the cooking appliance and the door 150 becomes correspondingly greater.

As the distance between the hot air discharged to the front of the cooking appliance and the door 150 increases, the risk of the temperature of the door 150 rising due to contact between the hot air and the door 150 decreases.

In addition, because the air discharged from the exhaust port 122 and the door exhaust port 152 moves through a space biased toward the upper part of the front space (S), the air discharged from the exhaust port 122 moves downward and reaches the door exhaust port 152. The possibility that air flowing into the door 150 or discharged from the door exhaust port 152 will flow back into the door 150 is reduced.

Since the air flow toward the front of the cooking appliance is directed toward the upper side away from the door exhaust port 152, the possibility of air flowing into the front space S flowing into the inside of the door 150 is very low.

To this end, the second guide unit 320 blocks the second space S2, which is a space adjacent to the door exhaust port 152, to prevent the movement of air through the space adjacent to the door exhaust port 152.

Additionally, the second guide unit 320 can induce upward movement of air introduced into the front space (S) by forming a blocking wall inclined upwardly toward the front.

As described above, the air guide 300 of this embodiment can not only effectively suppress the temperature of the door 150 from increasing due to hot air discharged to the front of the galley, but also can effectively prevent the temperature of the door 150 from increasing in the battlefield or inside the door 150. Backflow of discharged air into the door 150 can also be effectively prevented.

Referring to FIGS. 27 and 28 , the second guide portion 320 is in contact with the door 150 and may block the second space S2. More specifically, the second guide part 320 may be in contact with the rear half 150b of the door 150 and block the second space S2.

At this time, since the second guide portion 320 is disposed above the rear half 150b, at least a portion of the second guide portion 320 may be in contact with the rear half 150b from above. That is, the second guide portion 320 may be in contact with the rear half 150b at a position that overlaps the rear half 150b in the vertical direction.

As the second guide portion 320 and the rear half 150b come into contact in this way, the gap between the air guide 300 and the door 150 in the second space S2 can be blocked. Accordingly, the forward movement of air through the second space S2 can be effectively blocked by the second guide part 320.

According to this embodiment, the rear half 150b may be provided in a form that forms an inclined surface that slopes downward toward the rear. And the second guide portion 320 may be provided in a form that forms an inclined surface parallel to the rear half 150b.

Accordingly, at least a portion of the second guide portion 320 forms an inclined surface parallel to the inclined surface of the latter half 150b and may be in contact with the latter half 150b. The second guide part 320 and the second half 150b are in contact with each other in a vertically overlapping position, and at this time, the contact surface of the second guide part 320 and the second half 150b forms an inclined surface that slopes downward toward the rear. can do.

In addition, as the contact surface between the second guide part 320 and the second half 150b is formed to be inclined as described above, at least a portion of the second guide part 320 is positioned between the second half 150b and the second half 150b at a position lower than the top of the first half 150a. may be contacted.

To this end, the length of the second guide part 320 may be set to a length that allows the lower end of the second guide part 320 to reach a position lower than the upper end of the front half 150a.

As an example, the vertical length of the second guide part 320 is such that the lower end of the second guide part 320 can reach a position that is lower than the upper end of the front half (150a) and higher than the upper end of the door exhaust port 122. can be set.

Additionally, the front-to-back length of the second guide part 320 may be set to a length that allows the rear end of the second guide part 320 to be disposed between the front part 150a and the door exhaust port 150b. At this time, the rear end of the second guide part 320 may be disposed between the rear end of the front half 150a and the door exhaust port 150b in the front-back direction.

Accordingly, the second guide portion 320 and the latter half 150b may be in contact with each other in a position where they overlap each other in the vertical direction and also in the front-to-back direction.

As the second guide part 320 and the rear part 150b come into contact in this form, the gap between the air guide 300 and the door 150 in the second space S2 can be blocked more effectively. It becomes possible.

In addition, when the shape and length of the second guide part 320 are set as described above and the contact surface between the second guide part 320 and the latter half 150b is formed to be inclined, the second guide part 320 is connected to the door 150. While being disposed in a position where at least a portion of the second guide part 320 can overlap in the vertical direction, no part of the second guide part 320 may overlap the movement range of the door 150 .

Accordingly, the second guide part 320 can contact the door 150 at a position that does not impede the movement of the door 150. This second guide portion 320 can effectively block the gap between the air guide 300 and the door and block the second space S2 without interfering with the movement for opening and closing the door 150.

Meanwhile, the inner cover protrusion 220, which secures the air guide 300 to the control panel 200, can be disposed between the exhaust port 122 and the exhaust port 122, as shown in FIGS. 21 and 27. .

The inner cover protrusion 220 covers the partition 121 from the front of the partition 121 (see FIG. 19) so that it is not visible, and is disposed in a position that does not overlap the exhaust port 122, thereby forming the cover projections 210 and 220 or the air guide ( 300) can effectively lower the flow path resistance caused by this.

In addition, the front end 301 of the air guide 300 disposed on the front side of the front space S within the front space S as described above, that is, the front end 301 of the first guide portion 310, It may be placed in a position that overlaps at least a portion of the front glass 153 of the door 150 in the vertical direction.

As an example, the front end 301 of the air guide 300 is disposed at the same position as the rear end of the windshield 152 in the front-to-back direction, or is positioned at a position that protrudes further forward than the rear end of the windshield 152. can be placed.

In this way, the air guide 300 is disposed at a position biased toward the front within the front space (S), so that the flow of air flowing from the front space (S) toward the front of the cooking appliance is further controlled by the air guide (300). Can be guided effectively.

In addition, by arranging the air guide 300 in a position where the air guide 300 can be easily seen from the outside of the cooking appliance as described above, the aesthetics provided by the air guide 300 can be expressed more effectively.

Meanwhile, in the process of hot air being discharged from the front space (S), some of the discharged air comes into contact with the bottom of the control panel 200, which may cause condensation to form on the bottom of the control panel 200.

In this way, when the condensed water condensed on the bottom of the control panel 200 falls on the top of the door 150, the water that hits the door 150 splashes around the door 150 and contaminates the surrounding area.

As described above, when the air guide 300 is placed in a position biased toward the front within the front space (S), the control panel 200 and the door are connected to prevent condensate condensed at the bottom of the control panel 200 from falling on the door 150. (150) It can be a barrier between them.

Because the distance between the control panel 200 and the air guide 300 is much closer than the distance between the control panel 200 and the door 150, even if condensate falls on the air guide 300, the amount of water splashed around it is small. There won't be much.

That is, by using the air guide 300 arranged in the above-mentioned form, the occurrence of contamination around the cooking appliance due to condensate can be significantly reduced.

Additionally, in the air guide 300 of this embodiment, the second guide portion 320 is formed to be inclined downward and backward. Accordingly, condensed water falling on the air guide 300 may flow down the rear side of the door 150 along the inclined surface of the second guide part 320.

In particular, when the first guide portion is formed to be inclined downwardly toward the rear, such as the air guide 300a shown in FIG. 16 or the air guide 300c shown in FIG. 18, condensate can flow more effectively to the rear side of the door 150. .

In this way, the air guide can flow the condensate falling toward the door 150 to the rear side of the door 150, so that contamination around the cooking appliance due to condensate can be more effectively reduced.

In addition, the rear end 303 of the air guide 300, that is, the rear end 303 of the second guide part 320, may be disposed ahead of the door exhaust port 152 in the front-back direction.

Accordingly, a passage of sufficient height may be formed between the door exhaust port 152 and the air guide 300 for the air inside the door 150 to be discharged into the front space (S) through the door exhaust port 152.

As a result, the air discharged from the door exhaust port 152 is sufficiently mixed with the air discharged from the exhaust port 112 in the front space (S) before being able to pass through the section where the air guide 300 is placed.

In addition, if the rear end 300 of the air guide 300 is disposed in the above position, the air guide 300 does not become an obstacle placed vertically above the door exhaust port 152. By using this air guide 300, flow resistance around the door exhaust port 152 can be effectively reduced.

As another example, the front end 301 of the air guide 300 may be disposed in a position that coincides with at least one of the front end of the control panel 200 and the front end of the door 150 in the front-to-back direction. .

For example, when viewed from the side, the front end 301 of the air guide 300 and the front lower edge of the control panel 200 may be arranged on the same line. Additionally, when viewed from the side, the front end 301 of the air guide 300 and the front upper edge of the door 150 may be arranged on the same line.

By arranging the air guide 300 in this way, the positions of the control panel 200, the air guide 300, and the door 150 are aligned, and the appearance of the cooking appliance can appear more balanced, improving the aesthetics of the cooking appliance. This could be improved further.

In this way, the arrangement of the air guide 300 to improve the aesthetics of the cooking appliance is possible because the air guide 300 is skewed to the front side of the front space (S) within the front space (S).

That is, the air guide 300 of this embodiment is disposed biased toward the front side of the front space (S) within the front space (S), thereby suppressing the generation of vortices within the front space (S) and improving the aesthetics of the cooking appliance. It can also provide an improving effect.

The present invention has been described with reference to the embodiments shown in the drawings, but these are merely exemplary, and those skilled in the art will recognize that various modifications and other equivalent embodiments are possible therefrom.
