Referring to fig. 1 to 3, the present invention provides an embodiment of an electronic control box 200, which is suitable for being installed in an electrical apparatus as an electronic control device. For example, the electronic control box 200 may be applied to an air conditioner or other home appliances. The air conditioner may be a window type air conditioner 100 or a split type air conditioner. In the case of the window air conditioner 100, the electronic control box 200 may be installed in an indoor side casing of the window air conditioner 100 or in an outdoor side casing of the window air conditioner 100. For the split type air conditioner, the electric control box 200 may be installed in an indoor unit or an outdoor unit. In the following embodiment, description will be given mainly taking an example in which the electronic control box 200 is applied to the window air conditioner 100.

Referring to fig. 4 to 6, in an embodiment of the electronic control box 200 of the present invention, the electronic control box 200 includes a box body 210, and the box body 210 includes a bottom plate 211 and a box cover 212 covering the bottom plate 211. The box cover 212 includes an outer box cover 500 and an inner box cover 600 (as shown in fig. 7), wherein the edge of the inner box cover 600 is configured with a water blocking member 611, the water blocking member 611 protrudes outwards from the edge of the inner box cover 600 towards the edge of the outer box cover 500, and the water blocking member 611 is suitable for blocking water on the outer box cover 500 from flowing into the inner box cover 600.

Specifically, the electronic control box 200 may be disposed vertically; or the electronic control box 200 may be horizontally disposed. For example, the electronic control box 200 is vertically arranged, in this case, the box body 210 of the electronic control box 200 is vertical, and the box cover 212 of the box body 210 is opposite to the bottom plate 211 thereof in the front-back direction or the left-right direction; since the cover 212 covers the bottom plate 211, water falling on the top of the outer cover 500 is blocked by the water blocking member 611 on the inner cover 600 and thus cannot flow toward the inside of the inner cover 600, so that the water can be discharged downward only along the rear or side of the outer cover 500 and thus is not easily introduced into the inside of the inner cover 600.

For another example, the electronic control box 200 is horizontally arranged, in this case, the box body 210 of the electronic control box 200 is horizontally arranged, and the box cover 212 of the box body 210 is opposite to the bottom plate 211 thereof in an up-down direction; since the cover 212 covers the bottom plate 211, water falling on the top of the outer cover 500 is blocked by the water blocking member 611 on the inner cover 600, cannot flow toward the inside of the inner cover 600, but can be dropped downward only from the outer edge of the water blocking member 611 to be discharged, and since the outer edge of the water blocking member 611 is far from the inside of the inner cover 600, the water is not easily introduced into the inside of the inner cover 600.

The two ways of placing the electronic control box 200 can be selected reasonably according to the position of the electronic control box 200 in the application product, and are not limited herein. In order to avoid redundancy, in the following embodiments, description will be mainly made in such a way that the electronic control box 200 is vertically arranged.

In the technical scheme of the invention, the water retaining member 611 is configured at the edge of the inner layer box cover 600 of the electric control box 200, the water retaining member 611 extends outwards from the edge of the inner layer box cover 600 towards the edge of the outer layer box cover 500, and the water retaining member 611 is suitable for blocking water on the outer layer box cover 500 from flowing into the inner layer box cover 600, so that the waterproof performance of the electric control box 200 is improved, the occurrence of the condition that water in the external environment falls into the electric control box 200 is reduced, and further, the electric control components in the electric control box 200 are prevented from being damaged by moisture.

Referring to fig. 4, 7 and 8, in one embodiment, for the case 210 of the electronic control case 200, the bottom plate 211 of the case 210 includes an outer bottom plate 300 and an inner bottom plate 400, and the case cover 212 includes an outer case cover 500 and an inner case cover 600. Wherein, the outer cover 500 is made of metal material, and the inner cover 600 is made of plastic material; and/or, the outer base plate 300 is made of a metal material, and the inner base plate 400 is made of a plastic material.

Specifically, the case body 210 of the electronic control case 200 actually has an inner layer portion and an outer layer portion; wherein, the inner layer part is composed of an inner layer bottom plate 400 and an inner layer box cover 600, and the inner layer part (i.e. the inner layer bottom plate 400 and the inner layer box cover 600) is made of plastic materials, which is convenient for manufacturing and shaping and has low manufacturing cost. The outer layer part is composed of the outer layer bottom plate 300 and the outer layer metal box cover 212, and the outer layer part is made of metal, so that the electric control box 200 has a fireproof and antirust effect and higher safety performance. The water guard 611 is integrated with the inner box cover 600, and may be different from the additional manufacturing process, so as to improve the production efficiency.

Referring to fig. 4, 6 and 7, in an embodiment, the water guard 611 may be a water guard, or a water guard rib, or a water guard flange, or other structures that may play a role in water blocking. Specifically, the inner box cover 600 has an upper cover 610, the upper cover 610 corresponds to the top wall of the outer box cover 500, and a flange extends from the outer side edge of the upper cover 610 toward the outer side of the outer box cover 500, and the flange forms the water stop 611. Specifically, the side of the water guard 611 abuts against the upper edge of the outer cap 500, so that the gap between the outer cap 500 and the water guard 611 can be reduced.

When water from the external environment falls on the top of the outer cap 500, the water is not easily penetrated into the gap between the outer cap 500 and the water blocking member 611, and is discharged downward only from the side or rear surface of the outer cap 500. Of course, in addition to the water guard 611 formed on the upper cover 610, the water guard 611 may be formed on other edges (e.g., left and right side plates) of the inner box cover 600. Only in view of the water flowing down from above, water is not easily penetrated into the inside of the inner cap 600 from both sides of the outer cap 500, so the left and right side edges of the inner cap 600 may not need to be constructed with the water blocking member 611.

With continued reference to fig. 4, 6 and 7, in one embodiment, the top wall of the outer box cover 500 is provided with a mounting portion, and the mounting portion is provided with a mounting hole, and the mounting hole is suitable for a connector to pass through to connect and fix the box body 210 with an external structure. After the connecting member passes through the mounting hole, the inner end of the connecting member is located between the outer cap 500 and the inner cap 600, and if the connecting member is loosened from the mounting hole, water falling onto the outer cap 500 may also fall onto the inner cap 600 along the connecting member from the mounting hole. In view of this, a drain groove 640 corresponding to the mounting hole is constructed at the top of the inner box cover 600, and the drain groove 640 may receive water falling onto the inner box cover 600 from the mounting hole.

Referring to fig. 6, 12 and 13, considering that the outer cap 500 is not completely sealed with the water blocking member 611, when the amount of water falling on the outer cap 500 is large, there is a possibility that the water may accumulate in the gap between the outer cap 500 and the water blocking member 611 and further accumulate between the outer cap 500 and the inner cap 600, which may cause a large installation risk. To avoid this, the upper cover 610 of the inner cap 600 may be optionally inclined from the outside of the inner cap 600 toward the drain groove 640 toward the inside thereof. That is, an angle α (see fig. 14) is formed between the upper cover 610 and the horizontal plane, so that water permeated from the gap between the outer cap 500 and the water blocking member 611 flows into the drain groove 640 in the inclined direction of the upper cover 610, and then is discharged downward from the drain groove 640 through the rear surface of the inner cap 212.

Optionally, a plurality of supporting ribs 641 are protruded on the top of the inner box cover 600, and the plurality of supporting ribs 641 are adapted to support the top wall of the outer box cover 500, wherein the drainage groove 640 is formed between two adjacent ribs. Specifically, the plurality of support rib plates 641 cooperatively support the top wall of the outer box cover 500 to prevent the top wall of the outer box cover 500 from collapsing downward. A groove is formed between the adjacent two support rib plates 641, and one end of the groove is opened toward the rear surface of the inner box cover 212, so that the groove can be used as the drain groove 640, thereby allowing water supplied in the drain groove 640 to be drained downward toward the rear surface of the inner box cover 212. In other embodiments, of course, the top of the inner cover 600 may be directly concaved,

Referring to fig. 6, 12 and 13, in order to avoid water accumulation in the drain groove 640, in one embodiment, a drainage groove 650 extending in an up-down direction is configured on the back surface of the inner box cover 600, an upper end of the drainage groove 650 is in butt joint with the drain groove 640, and a lower end of the drainage groove 650 extends to the bottom of the inner box cover 600. By such design, the water in the water drain groove 640 can flow downwards along the drainage groove 650, and finally is discharged from the gap at the bottom of the box 210, so as to avoid being accumulated in the box 210.

In order to facilitate the water in the drainage channel 640 to enter the drainage channel 650, optionally, the upper end of the drainage channel 650 is arranged in a necking shape from top to bottom, so that the resistance of the upper end of the drainage channel 650 to water flow is small, the water in the drainage channel 640 is guided by the necking of the upper end of the drainage channel 650, and can smoothly enter the drainage channel 650, and splashing of water flow is reduced.

Referring to fig. 7, 8 and 12, according to any of the above embodiments, it is possible to enter the inside of the electronic control box 200 from the assembly gap between the bottom plate 211 and the box cover 212, considering that water splashed onto the bottom plate 211 from the external environment. To reduce this, the inner box cover 600 may have a first side plate 620 and a second side plate 630 opposite to each other, and the inner box cover 600 may be configured with a slot 660, the slot 660 extending from the first side plate 620 to the second side plate 630 through the upper cover plate 610, and both ends of the slot 660 being opened downward; the bottom plate 211 includes an outer bottom plate 300 and an inner bottom plate 400, and the periphery of the inner bottom plate 400 is configured with an insertion portion 420 (shown in fig. 12 and 13) corresponding to the insertion groove 660.

When the case body 210 of the electronic control case 200 is assembled, the insertion part 420 of the bottom plate 211 is inserted and connected with the insertion groove 660 of the inner case cover 600, so that the inner case cover 600 covers the bottom plate 211. Since the electronic control box 200 is vertically arranged, the openings at the two ends of the slot 660 are downward, if the external environment splashes into the assembly gap between the bottom plate 211 and the box cover 212, the external environment firstly enters the slot 660 of the inner box cover 600 and then is discharged downwards along the slot 660 to the openings at the two ends of the slot, so that the waterproof performance of the electronic control box 200 is greatly improved.

Referring to fig. 12 and 15, further, the insertion part 420 has an upper surface corresponding to the upper cover 610 of the inner box cover 600, and the upper surface of the insertion part 420 is inclined downward from the inside of the inner box cover 600 to the outside thereof. That is, the upper surface of the insertion portion 420 forms an angle β with the horizontal plane. Therefore, even if water enters from the slit between the upper cover plate 610 and the insertion portion 420, this water is discharged downward and outward along the upper surface of the insertion portion 420 when contacting the upper surface of the insertion portion 420, and is difficult to enter into the slot 660.

Referring to fig. 7, 8 and 10, in an embodiment, in order to improve the waterproof performance of the case 210 of the electronic control case 200, the assembly position between the bottom plate 211 of the case 210 and the case cover 212 may be sealed. Optionally, a sealing groove 421 is further configured on the insertion portion 420 of the inner bottom plate 400, an extending direction of the sealing groove 421 is consistent with an extending direction of the insertion portion 420, and a sealing strip 430 (as shown in fig. 13) is configured in the sealing groove 421.

Specifically, the sealing strip 430 is made of elastic waterproof material such as rubber or silica gel. When the sealing strip 430 abuts against the inner surface of the slot 660, the sealing strip 430 may elastically deform so as to tightly abut against the inner surface of the slot 660, thereby reducing the gap between the slot 660 and the insertion portion 420 and reducing the possibility of water infiltration from the gap.

Further, a positioning protrusion 661 may be provided on an inner surface of the slot 660 toward the sealing groove 421, and the positioning protrusion 661 extends into the sealing groove 421 and abuts against the sealing strip 430. The slot 660 is abutted to the sealing strip 430 through the positioning protrusion 661, so that the sealing strip 430 can be pressed in the sealing groove 421, the elastic deformation of the sealing strip 430 is increased, and the sealing strip 430 is abutted to the positioning protrusion 661 more tightly, so that the sealing effect is better.

Referring to fig. 7, 8 and 9, in one embodiment, the electric control box 200 further includes an electric control board 220 and a reactor 230 mounted on the bottom board 211; the inner-layer box cover 600 is internally provided with a main cavity 601 and a sub-cavity 602, wherein the main cavity 601 is suitable for accommodating elements on the electric control board 220, and the sub-cavity 602 is suitable for accommodating the reactor 230.

Referring to fig. 9, 10 and 16, it is considered that during operation of the electronic control box 200, the electronic control board 220 generates a large amount of heat, such as not being discharged outwards in time, which may cause the temperature inside the electronic control box 200 to be too high to burn out the electronic control board 220. Based on this, the bottom plate 211 includes an outer bottom plate 300 and an inner bottom plate 400, and the inner bottom plate 400 is hollowed out at a position corresponding to the electric control plate 220, so that a heat dissipation area is formed between the electric control plate 220 and the outer bottom plate 300.

Specifically, since the outer bottom plate 300 is made of a metal material and the inner bottom plate 400 is made of a plastic material, the heat transfer efficiency of the outer bottom plate 300 is greater than that of the inner bottom plate 400 due to the difference in properties of the materials. Therefore, the electric control board 220 and the outer bottom board 300 are formed with a heat dissipation area by being hollowed out at the position of the inner bottom board 400 corresponding to the electric control board 220, so that the electric control board 220 directly radiates heat to the outer bottom board 300 through the heat dissipation gap, and finally radiates outwards through the outer bottom board 300.

The grill support 440 is formed at the hollowed-out position 410 of the inner bottom plate 400, and the grill support 440 is suitable for separating the outer bottom plate 300, so that the outer bottom plate 300 can be prevented from being pressed towards the hollowed-out position 410 by external extrusion force to contact with the electric control plate, thereby avoiding overheating of the outer bottom plate 300, avoiding occurrence of electric leakage of the electric control plate 220 through the outer bottom plate 300, and improving the safety performance of the electric control box 200.

Referring to fig. 16 and 17, in theory, the larger the distance between the electric control board 220 and the outer bottom board 300 (as shown by D ₂ in fig. 17), the more advantageous the heat dissipation is based on the above embodiment; but correspondingly, the space inside the electronic control box 200 is additionally occupied, so that the overall volume of the electronic control box 200 is increased. Therefore, the interval between the electric control panel 220 and the exterior bottom panel 300 should be maintained within a certain range.

According to the research, when the distance between the electric control plate 220 and the outer bottom plate 300 is not smaller than 8mm and not larger than 18mm, a larger gap can be obtained between the electric control plate 220 and the outer bottom plate 300, so that the electric control box 200 has better heat dissipation efficiency and safety performance, occupies smaller space, and can still keep the whole volume of the electric control box 200 smaller. Accordingly, the spacing between the electronic control panel 220 and the outer floor 300 may be selected to be no less than 8mm and no greater than 18mm. Such as, but not limited to: 8mm, 10mm, 12mm, 15mm, 16mm, 17mm, etc. The corresponding design may be specifically performed according to the size of the electronic control board 220, and there is no specific limitation herein.

Referring to fig. 6 and 8, in an embodiment, in order to improve the heat dissipation efficiency of the electronic control box 200, a heat dissipation gap is formed between the side wall of the main cavity 601 and the outer box cover 500, and a heat dissipation hole 680 corresponding to the heat dissipation gap is further formed through the side wall of the main cavity 601. The plurality of heat dissipation holes 680 are arranged at intervals up and down. The heat in the main cavity 601 can be rapidly dissipated into the gap between the inner and outer covers 600 and 500 by the plurality of heat dissipation holes 680, and then dissipated outward through the outer cover 500.

It is also contemplated that moisture from the external environment may penetrate into the interior through the gaps in the case body 210 (e.g., the gaps between the outer base plate 300 and the outer cover 500, or the gaps at the connection location of the electronic control box 200 and the housing of the product to which it is applied), and further enter the main cavity 601 through the heat dissipation holes 680, causing the electronic control board 220 to get wet and malfunction.

To avoid this, a water blocking plate 681 may be protruded at the periphery of the heat dissipation hole 680, the water blocking plate 681 surrounds the heat dissipation hole 680, and the water blocking plate 681 is disposed to be inclined from the inner side of the heat dissipation hole 680 to the outer side thereof. Therefore, when the water in the external environment is blocked and guided by the water blocking board 681 to drop down in sequence (the dotted arrow in fig. 6 indicates the draining direction), the water flows to the bottom of the box 210, and finally is discharged from the gap at the bottom of the box 210 to the chassis 110, so that the water drops are prevented from entering the main cavity 601 through the heat dissipation holes 680, and the occurrence of faults caused by the wetting of the electric control board 220 is reduced.

Referring to fig. 6, 8 and 17, in one embodiment, the electronic control box 200 further includes a heat sink 240 mounted on the electronic control board 220, and a sealing sleeve 250 is disposed around the heat sink 240; the inner box cover 600 is provided with an extension opening 603 corresponding to the radiator 240 extending outwards, a countersink 690 is formed on the inner circumference of the extension opening 603, and the countersink 690 is correspondingly embedded with the sealing sleeve 250.

Specifically, the heat sink 240 includes a base plate 241 and a plurality of heat dissipation fins 242 configured on the base plate 241, and the base plate 241 is mounted on the electronic control board 220. The sealing sleeve 250 is sleeved on the base plate 241 in a ring mode. When the electronic control box 200 is assembled, the radiating fins 242 of the radiator 240 protrude outwards from the protruding opening 603, and the sealing sleeve 250 is inserted into the sinking groove 690, so that the sealing sleeve 250 is used for sealing the gap between the protruding opening 603 and the circumference of the radiator 240, and water in the external environment is prevented from penetrating into the electronic control box 200 from the gap.

With continued reference to fig. 8, fig. 6 and fig. 17, further, a plurality of annular ribs 691 are protruding from the surface of the sink 690, the plurality of annular ribs 691 sequentially encircle the circumference of the outlet 603, and the annular ribs 691 are abutted against the surface of the sealing sleeve 250. The plurality of annular ribs 691 are propped against the surface of the sealing sleeve 250, so that under the compression force of the annular ribs 691, the surface of the sealing sleeve 250 is elastically deformed and is propped against the annular ribs 691 more tightly, thus gaps between the radiator 240 and the periphery of the extending outlet 603 can be effectively reduced, the occurrence of the condition that external water is permeated into the electric control box 200 from the periphery of the radiator 240 can be reduced, and the waterproof performance of the electric control box 200 is improved.

The number of the annular ribs 691 is not limited, and may be two or more. The annular ribs 691 are arranged in a zigzag shape along the periphery of the extending opening 603, and the annular ribs 691 are matched and abutted against the surface of the sealing sleeve 250, so that a multi-layer seal is formed on the periphery of the radiator 240, and the sealing waterproof effect is greatly improved. The annular ribs 691 may be arranged in any annular shape, and may be of regular or irregular annular design. For example, but not limited to, annular bead 691 is of polygonal (e.g., square, trapezoidal, pentagonal, etc.) design, or of circular design, or of oval design, etc. In practical applications, the annular ribs 691 are preferably consistent with the protrusions 603, and may be designed according to the specific shape and structure of the heat sink 240.

Referring to fig. 1 to 3, the present invention further provides a window air conditioner 100, where the window air conditioner 100 includes a chassis 110, a casing 120, an outdoor fan 160, and an electric control box 200. The specific structure of the electronic control box 200 refers to the above embodiment, and since the window air conditioner 100 adopts all the technical solutions of all the embodiments, the window air conditioner also has all the beneficial effects brought by the technical solutions of the embodiments, and will not be described in detail herein.

Referring to fig. 1 to 3, in an embodiment, the casing 120 is mounted on the chassis 110, the casing 120 includes an outdoor side casing 122 and an indoor side casing 121, and a top plate of the outdoor side casing 122 is provided with an outdoor side air inlet 170; the outdoor fan 160 is installed in the outdoor side case 122; the electric control box 200 is installed on the outdoor side casing 122, and the electric control box 200 is vertically arranged and corresponds to the air inlet side of the outdoor fan 160.

Specifically, the outdoor side air inlet 170 has an air inlet side 171 far from the outdoor fan 160, the cover 212 of the electric control box 200 corresponds to the air inlet side 171, and the water blocking member 611 of the cover 212 is located on a side of the air inlet side 171 opposite to the outdoor side air inlet 170. Therefore, the water falling onto the cover 212 of the electronic control box 200 from the outdoor side air inlet 170 is blocked by the water blocking member 611 and can only be discharged downwards from the back of the cover 212, so that the water is difficult to cross the water blocking member 611 and fall to the assembling position between the cover 212 and the bottom plate 211, and is difficult to infiltrate into the electronic control box 200.

It is considered that when water in the external environment falls onto the cover 212 of the electronic control box 200 from the outdoor side air inlet 170, the water drops collide with the top wall of the outer cover 500 to splash the water drops in the circumferential direction, and the splashed water drops may cross the water guard 611. Therefore, in order to avoid splashed water droplets crossing the water deflector 611, it is defined herein that the distance between the water deflector 611 and the tuyere side 171 is not less than 6mm.

Referring to FIGS. 12 to 14, the dashed arrow in FIG. 14 indicates the direction of water discharge, and D ₁ is indicated as the distance between the water deflector 611 and the tuyere side 171, that is, D ₁. Gtoreq.6 mm. The diameter of the splashed water droplets spread around is generally less than 6mm. By defining the distance between the water guard 611 and the tuyere side 171 to be not less than 6mm, it is possible to allow splashed water droplets to fall again onto the top wall of the outer cap 500 without crossing the water guard 611 and then flow from the top wall of the outer cap 500 to the rear surface thereof.

Of course, the larger the distance between the water guard 611 and the tuyere side 171 is, the larger the distance is, the larger the space occupied by the electronic control box 200 is, which is disadvantageous in saving the installation space. It is therefore defined herein that the distance between the water deflector 611 and the tuyere side 171 is not more than 50mm, i.e. 6 mm. Ltoreq.D ₁≤50mm.D₁ may be, but is not limited to: 6mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 48mm, etc.

Specifically, by limiting D ₁ to 50mm, which is 6mm or less, it is ensured that splashed water drops are difficult to cross the water guard 611, and the space occupied by the control box is also small, so that the electric control box 200 is convenient to be installed in a narrow space on the air inlet side of the outdoor fan 160. It should be noted that the tuyere side 171 may be a straight edge or a non-straight edge; when the tuyere rear side is a non-straight side, the aforementioned distance between the water guard 611 and the tuyere side 171 should refer to the minimum distance between the water guard 611 and the tuyere side 171.

It is considered that if the electric control box 200 is only connected and fixed to the chassis 110 through the bottom thereof, but the top of the electric control box 200 is not fixed, the electric control box 200 may swing back and forth and collide with the adjacent components (such as the outdoor fan 160 or the fan bracket 170) during the process of carrying the transferring window type air conditioner 100, so that the fireproof or antirust coating on the surface of the electric control box 200 is scratched and fails, and there is a great safety hazard.

In an embodiment, in order to reduce the occurrence of the above situation, the top plate of the outdoor side casing 122 is provided with a fixing portion 180, and the fixing portion 180 is adapted to be connected and fixed with the mounting portion 510 at the top of the electronic control box 200 by using a connecting member. Specifically, the fixing portion 180 is provided with a through hole, the mounting portion 510 is provided with a docking hole, and the electronic control box 200 and the outdoor side casing 122 are connected and fixed by sequentially passing through the through hole and the docking hole by using a connecting member. Wherein the connection member may be a screw. The mounting portion 510 protrudes from the top surface of the electronic control box 200, so that external water can be reduced from penetrating into the electronic control box 200 through the butt hole of the mounting portion 510.

When the top of the electronic control box 200 is connected to the fixing portion 180 of the outdoor side casing 122 through the mounting portion 510, the position of the top of the electronic control box 200 is fixed, that is, the bottom and the top of the electronic control box 200 are both fixed, so that the electronic control box 200 is not easy to swing, thereby reducing the occurrence of collision between the electronic control box 200 and adjacent components thereof.

Referring to fig. 1 and 21, in one embodiment, the casing 120 is mounted on the chassis 110, a separation groove 123 into which a shutter at a window is inserted is formed in the casing 120, and the casing 120 is separated into an indoor side casing 121 and an outdoor side casing 122 by the separation groove 123; the outdoor fan 160 is installed at the outdoor side case 122; the electric control box 200 is installed in the outdoor side casing 122, the electric control box 200 is vertically arranged, and the radiator 240 of the electric control box 200 faces the outdoor fan 160.

In particular, the dividing channel 123 is adapted to allow a shutter located at a window of a wall to extend into. After the window type air conditioner 100 is mounted on the window of the wall body, the outdoor side cover 212 is positioned outdoors, and the indoor side cover 212 is positioned indoors, so that noise generated from the outdoor side can be prevented from being transmitted to the indoor side, and a noise reduction effect is achieved. Then, the shielding member is pulled down to protrude into the separation groove 123 of the window type air conditioner 100, and shields the gap between both sides of the window type air conditioner 100 and the side walls of the window, so that the leakage of indoor cold or heat from the space to the outside can be reduced. It should be noted that the shielding member may be a window sash, a window shutter, a curtain, or the like, or may be other protective window plates or the like that can shield an external object from entering a room.

The window air conditioner 100 further includes an indoor heat exchanger 130, an outdoor heat exchanger 140, an indoor fan 150, and an outdoor fan 160. Wherein the indoor heat exchanger 130 and the indoor fan 150 are installed in the indoor side case 121; the outdoor heat exchanger 140 and the outdoor fan 160 are installed in the outdoor side case 122. When the window air conditioner 100 is in operation, the indoor fan 150 drives indoor air into the indoor side housing 121 to exchange heat with the indoor heat exchanger 130, and blows the exchanged air from the indoor side housing 121 to the indoor environment, so as to realize cooling and heating of the indoor environment. At the same time, the outdoor fan 160 drives the outdoor air into the outdoor side case 122 to exchange heat with the outdoor heat exchanger 140, and blows the heat exchanged air from the outdoor side case 122 to the outdoor environment. The electric control box 200 is vertically installed in the outdoor side housing 122, and the electric control box 200 is located at the air inlet side of the outdoor fan 160, so that when the window type air conditioner 100 operates, air flow driven by the outdoor fan 160 passes around the electric control box 200, and a part of heat generated by the electric control box 200 is taken away.

Referring to fig. 21 and 22, referring to fig. 10 and 11, in an embodiment, the window air conditioner 100 further includes a sealing member 700, the sealing member 700 is movably mounted on the partition groove 123, and the sealing member 700 is adapted to be moved to switch between a storage state and an operation state; wherein: in the accommodated state, the seal 700 is accommodated in the partition groove 123; in said operating condition, the seal 700 protrudes laterally from the dividing groove 123, adapted to be held against the inner wall of the shutter and/or said window.

After the window is installed with the window type air conditioner 100, the sealing member 700 is moved to the working state, so that the sealing member 700 extends laterally from the separation groove 123 of the window type air conditioner 100, and the bottom surface of the sealing member 700 is abutted against the bottom wall of the window; then, the shielding member is pulled down to extend into the partition groove 123 of the window type air conditioner 100 until the lower edge of the shielding member contacts with the partition member and the sealing member 700, the sealing member 700 shields and seals the gap between the shielding member and the bottom wall of the window until now, and the cold or heat in the room is reduced from leaking to the outside from the gap. When the window air conditioner 100 is not needed or transported, the sealing member 700 is moved to the storage state, so that the space occupied by the sealing member 700 is reduced, and the window air conditioner 100 is conveniently stored or packaged.

There are a variety of ways in which the seal 700 may be movably mounted. For example, the seal 700 is slidably mounted on the partition groove 123; or the seal 700 is rotatably installed to the separation groove 123; or alternatively, the sealing member 700 may be elastically and telescopically mounted to the partition groove 123. Specifically, here, the seal 700 is rotatably mounted to the partition groove 123 to be switched between the operating state and the storage state by rotation.

The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
