Description

  The present invention relates to an electric baking machine. More specifically, cooking is performed by separating components at a predetermined interval so that the heat generated by the heater heats the cooked food by a convection phenomenon and then naturally flows out to the outside. Not only can heat be applied to the object evenly to make delicious dishes, but also heat can be prevented from being directly transferred to the outer cover made of plastic injection, preventing the side cover and boss from melting. It relates to an electric baking machine.

In general, homes, restaurants, and the like are equipped with an electric grill for cooking meat.
A conventional electric baking machine uses a halogen, carbon lamp, or the like as a heat source, and is configured to heat a baking plate with the lamp and to bake the food on the baking plate.
As a conventional technique related to this, Patent Document 1 discloses an electric baking machine. As shown in FIG. 1, the structure includes a fuselage A2 in which a large number of suction holes 5 are formed, and a fuselage B2 ′ that is detachably coupled to the bottom surface of the fuselage A2 and communicates with the oil discharge port 6 internally. A large number of air holes 16 are formed on the surface and are provided on the bottom surface of the baking plate 14 heated by power supply, and the operation of the suction fan 10 is controlled by sensing the temperature of the baking plate 14. And a storage space 23 formed therein, an oil receiver 18 provided at the lower end of the body B2 ′ so as to be able to be pulled out to the outside, and the suction hole 5 of the body A2 above the baking plate 14. And a large number of auxiliary baking plates 25 so as to be detachable.
In such a conventional technique, when the material placed on the baking plate 14 is baked to an appropriate level, the material is prevented from being burned by being placed on the auxiliary baking plate 25 that receives relatively little heat. At the same time, the temperature of the material is maintained at an appropriate level, and smoke and oil vapor generated from the material placed on the auxiliary baking plate 25 and diffusing to the outside through the suction holes 5 ′ formed on the outer peripheral surface of the auxiliary baking plate 25. By inhaling and flowing into the inflow spaces 3, 3 ', the electric baking apparatus is used more efficiently.
However, in the case of the prior art, since the baking plate 14 is heated by the heat wire 17 installed on the bottom surface of the baking plate 14, the heat of the hot wire 17 cannot uniformly heat the baking plate 14, and the baking is performed. Since the temperature deviation of the plate 14 is severe, cooking is performed early if the position of the food placed on the baking plate 14 is close to the hot wire 17, and late if the position of the food placed on the baking plate 14 is far from the hot wire 17. There was a problem of being cooked. In addition, the portion where the heat ray 17 directly contacts the food or drink placed on the grill 14 is easily burnt, and the contents cannot be burnt well, so that there is a problem that the food and drink cannot be cooked uniformly.
Further, since the ends of the baking plate 14, the support 11 and the body A2 are in contact with each other, even if the suction fan 10 installed at the lower part of the electric baking machine rotates, Since there is a limit to the convection of heat inside, there is a drawback that the food cannot be heated uniformly with heat.
On the other hand, in the conventional electric baking machine, since each component is installed in contact with each other without any interval, in the case of a component made of plastic injection, the heat of the baking plate 14 is directly transmitted and melts. There has occurred.

FIG. 2 is an exploded perspective view showing the electric baking apparatus of the present invention, and FIG. 3 is an assembled sectional view showing the electric baking apparatus of the present invention.
The electric baking apparatus 100 according to the present invention includes a heater 110 that dissipates heat when a power source is applied, a heater protection cover 120 installed on the upper surface of the heater 110, and a number of oil distribution holes 132. The baking plate 130 for heating the food placed on the upper surface by heat, the oil receiver 140 in which the oil receiving groove 142 is formed at a position corresponding to the oil distribution hole 132 of the baking plate 130, and the heat of the heater 110. Reflecting plate 150 for reflecting to the baking plate 130, an intermediate plate 160 having a separating means for cutting off the heat of the heater 110 and keeping a predetermined distance from the oil receiver 140, and an arbitrary position inside An outer cover 170 provided with a plurality of bosses 172 and an inner center of the outer cover 170 to heat the heater 110 to an electric baking machine. It includes a fan 180 for causing convection therein and a lid 190 having a handle 192.
As the heater 110, a carbon lamp is preferably used, but it goes without saying that various lamps such as a halogen lamp can be applied.
As shown in FIG. 5, the heater protection cover 120 is installed on the upper surface of the heater 110, and heat generated in the heater 110 is transmitted to the baking plate 130 through the heater protection cover 120. A large number of heat inflow holes 122 are formed.
The heat inflow holes 122 are formed radially in the heater protection cover 120, and the number and shape thereof are not limited in the present invention.
Meanwhile, the heater protection cover 120 includes a plurality of embossments 124 to be installed separately from the baking plate 130. The emboss 124 protrudes upward from the upper surface of the heater protection cover 120.
The embossing 124 is preferably formed at regular intervals, and in the embodiment of the present invention, eight are formed at an angle of 45 °. However, the formation interval of the emboss 124 is not limited to this, and the number thereof is not limited.
The embossing 124 protrudes upward to a predetermined height, and the protruding height is preferably 1.2 to 2.2 mm. In addition, as shown in FIG. 8, the emboss 124 may be formed obliquely so that the height increases as it goes to the outer peripheral surface of the heater protection cover 120.
When the baking plate 130 is placed on the upper surface of the heater protection cover 120 by the embossing 124 as described above, the heater protection cover 120 and the baking plate 130 can be installed separately.
In addition, a bent portion 126 having a step is formed on the upper edge of the heater protection cover 120, and a step is formed on the baking plate 130 so that the step can be attached to the bent portion 126. 134 is provided.
FIG. 8 of the accompanying drawings is a cross-sectional view showing the coupling relationship between the baking plate and the heater protective cover in the present invention. As shown in the figure, a bent portion 126 that is bent in two steps is formed at the upper end of the heater protection cover 120, and a stepped portion is formed on the baking plate 130 at a position corresponding to the bent portion 126. 134 is formed, and when the baking plate 130 is placed on the heater protection cover 120, the stepped portion 134 is configured to be attached to the bent portion 126.
Here, the stepped portion 134 and the bent portion 126 are not formed so that their shapes correspond exactly, and a plurality of embosses 124 are formed inside the bent portion 126 at regular intervals. Therefore, the stepped portion 134 is attached to the bent portion 126 but cannot be fitted.
Such a combined state can be said to be a semi-fixed state. As described above, the stepped portion 134 is attached to the bent portion 126 in a semi-fixed state, thereby preventing the baking plate 130 from sliding and preventing the heater 110 from sliding on the heater protection cover 120. The heat dissipated from the air flows out to the outside through the space between the stepped portion 134 and the bent portion 126, so that the heat can be prevented from being confined.
That is, an interval is generated when the baking plate 130 is placed on the heater protection cover 120, and thermal convection is performed between them. In this way, the problem that the parts are damaged due to the heat not confined and convectively flowing to the outside can be solved. When the heat of the heater 110 is convected by the fan 180, a part of the heater is heated. While being discharged into the space between the protective cover 120 and the baking plate 130, the cooked food on the baking plate 130 is heated to be uniformly baked.
According to the applicant's experiment, if the baking plate 130 is in contact with the heater protective cover 120 and heated by heat conduction, the upper portion of the baking plate 130 in contact with the heater 110 is heated to 250 ° C., Since the edge of the baking plate 130 is heated only to a temperature of 80 to 90 ° C., there is a problem that the food on the baking plate 130 is not heated uniformly.
Therefore, in the present invention, the baking plate 130 and the heater protection cover 120 are separated from each other, and heat is exhausted through the space between the heater protection cover 120 and the baking plate 130, and the food on the baking plate 130 is removed by heat convection. It was made possible to bake evenly.
Meanwhile, a recessed portion 128 is formed in the central portion of the heater protection cover 120.
The recess 128 is for receiving meat or oil falling from the baking plate 130, and an air inlet 136 is formed in the center of the baking plate 130 so as to extend upward and open. A heater is formed through the air inlet 136. Although the heat of 110 flows in, foreign substances can fall to the heater 110 side through the air inlet 136 when meat or the like is baked on the baking plate 130. In this case, the recess 128 receives the foreign matter, thereby preventing the foreign matter from entering the heater protective cover 120.
An oil pan 140 is installed below the baking plate 130. In the oil receiver 140, an oil receiving groove 142 is formed at a position corresponding to the oil distribution hole 132 of the baking plate 130, and a through hole 144 in which the heater protection cover 120 is installed is formed in the center. The heater protection cover 120 is inserted into 144.
Meanwhile, the upper end of the through hole 144 of the oil receiver 140 is located below the heater 110. As described above, the upper end of the through hole 144 of the oil receiver 140 is located below the heater 110, thereby preventing the oil receiver 140 from being directly heated by the heater 110 and preventing the temperature of the oil receiver 140. Can be lowered as much as possible.
Since the oil receiver 140 is installed in the vicinity of the heater 110 and is usually made of a metal material, it can be easily heated when cooking meat or the like. If the oil receiver 140 is heated as described above, a component made of a plastic injection material, for example, the outer cover 170 and the boss 172 come into contact with the oil receiver 140 and melts. In the present invention, in order to solve such problems, a separation space is formed between the heater protection cover 120 and the oil receiver 140.
That is, as shown in the enlarged view of FIG. 3, the oil receiver 140 is attached to the heater protective cover 120 by separating the heater protective cover 120 and the oil receiver 140 by a predetermined distance (a). It was installed so as not to be in direct contact.
Thus, the present invention can minimize the degree to which the oil receiver 140 is heated by the heater 110 by forming the separation space (a) between the heater protection cover 120 and the oil receiver 140. .
Meanwhile, an intermediate plate 160 is installed below the oil receiver 140. If the intermediate plate 160 is in contact with the oil receiver 140 over a wide area, there is a problem that the temperature transmission surface becomes a whole. Therefore, in order to minimize the temperature transmission surface of the intermediate plate 160 and the oil receiver 140, In the present invention, the separating means is provided so that the oil receiver 140 and the intermediate plate 160 come into contact with each other by point contact.
FIG. 9 of the accompanying drawings is a perspective view showing the intermediate plate of the present invention, and FIG. 10 is a sectional view of the intermediate plate of the present invention.
The intermediate plate 160 is formed with a through hole 162 at the center so that air from the fan 180 passes through, and an embossed surface 164 is formed on the surface of the oil receiver 140 in contact with the oil receiving groove 142 as the separating means.
In the present invention, the embossing 164 is formed as the separation means, but the separation means is not limited to this, and may be a bolt or a bracket.
In addition, the emboss 164 may include an upward emboss projecting upward and a downward emboss projecting downward. In this case, it is preferable that the upward embossing and the downward embossing are alternately formed.
The intermediate plate 160 is assembled to the heater protection cover 120 with screws. For this purpose, screw assembly holes 166 are formed in the intermediate plate 160 at regular intervals.
A vertical guide 168 having a predetermined height is formed at the edge of the intermediate plate 160. Since the vertical guide 168 is formed at the edge of the circular intermediate plate 160, the vertical guide 168 is formed in an annular shape, and the oil receiver 140 is fixed by the vertical guide 168 so that the oil receiver 140 moves. Can be prevented.
Meanwhile, an outer cover ring 174 made of a metal material, for example, a stainless steel material, is installed at the upper end of the outer cover 170.
The outer cover ring 174 is formed with a protrusion (not shown) that protrudes inward and outward so as not to be separated from the outer cover 170 by thermal contraction and expansion.
In the present invention, the intermediate plate 160 and the outer cover 170 are installed so as to form a separation space therebetween, and when the heat of the heater 110 is convected by the fan 180, the separation between the intermediate plate 160 and the outer cover 170 is performed. The heat is prevented from being trapped by being discharged through the space.
The outer cover 170 is provided with a plurality of bosses 172 at arbitrary positions inside. The boss 172 is used to install the intermediate plate 160. In the present invention, a heat insulating washer 176 is installed to prevent heat from being conducted to the upper end of the boss 172.
Here, the washer 176 may be made of a silicon material.
Thus, in the present invention, the heat of the oil receiver 140 is not directly transmitted to the boss 172 by the washer 176, so that the phenomenon of the boss 172 melting can be prevented.
Meanwhile, a fan 180 for convection of the heat of the heater 110 to the inside of the electric oven is installed in the center of the outer cover 170.
FIG. 11 is an exploded perspective view showing the fan assembly of the present invention. A heat insulating plate 182 for preventing heat from the heater 110 from being directly transferred to the fan 180 is installed on the fan 180, and a fan cover 184 is installed on the heat insulating plate 182.
The fan cover 184 may be made of a metal material. In an embodiment of the present invention, the fan cover 184 is installed as a separate component, but the fan cover 184 is formed integrally with the intermediate plate 160. Can also be done.
In the electric baking apparatus according to the present invention, when the fan 180 is driven as shown by an arrow in FIG. 12, the heat of the heater 110 is convected by separating the components at predetermined intervals. The product can be heated evenly by convection through the inside of the electric baking oven depending on the phenomenon, and then the product can be cooked deliciously by being naturally discharged to the outside. Can be prevented from being damaged.
As described above, the present invention has been described based on specific embodiments and drawings. However, the present invention is not limited to the above-described embodiments, and a person having ordinary knowledge in the field to which the present invention belongs. Various modifications and variations can be made from such description.
Accordingly, the spirit of the present invention should be understood only by the claims described below, and any equivalent or equivalent modification thereof belongs to the spirit category of the present invention.

  In the present invention, the heat is uniformly applied to the food by separating the components at a predetermined interval so that the heat generated by the heater heats the food by a convection phenomenon and then flows out to the outside naturally. It can be applied not only to delicious dishes, but also to an electric baking machine that can prevent heat from being transferred directly to the outer cover made of plastic injection and prevent the side cover and boss from melting. .
