For example, the electrical 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 type air conditioner 100, the electrical control box 200 may be installed in an indoor side housing of the window type air conditioner 100, or may be installed in an outdoor side housing of the window type air conditioner 100. For the split type air conditioner, the electrical control box 200 can be installed in both indoor and outdoor units. In the following embodiments, the electric control box 200 is mainly applied to the window type air conditioner 100 as an example.

Referring to fig. 4 to 6, in an embodiment of the electrical control box 200 of the present invention, the electrical 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-layer box cover 500 and an inner-layer box cover 600 (as shown in fig. 7), the edge of the inner-layer box cover 600 is configured with a water blocking member 611, the water blocking member 611 extends outward from the edge of the inner-layer box cover 600 toward the edge of the outer-layer box cover 500, and the water blocking member 611 is adapted to block water on the outer-layer box cover 500 from flowing toward the inside of the inner-layer box cover 600.

Specifically, the electrical control box 200 may be vertically disposed; alternatively, the electrical control box 200 may be horizontally disposed. For example, the electrical control box 200 is vertically arranged, in this case, the box body 210 of the electrical 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 cannot flow to the inside of the inner cover 600, so that the water can only drain down along the back or side of the outer cover 500 and is not easy to enter the inside of the inner cover 600.

For another example, the electrical control box 200 is horizontally disposed, in this case, the box body 210 of the electrical control box 200 is horizontal, and the box cover 212 of the box body 210 is opposite to the bottom plate 211 thereof in the vertical 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 cannot flow to the inside of the inner cover 600, but can only drip down 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 away 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 electrical control box 200 can be reasonably selected according to the position of the electrical control box 200 in the application product, and no limitation is set herein. For avoiding redundant description, in the following embodiments, the description is mainly given in a manner that the electronic control box 200 is vertically disposed.

The technical scheme of the utility model, the edge structure through the inlayer lid 600 at automatically controlled box 200 has water blocking part 611, water blocking part 611 certainly the edge court of inlayer lid 600 the edge of outer lid 500 is outwards stretched out, water blocking part 611 is applicable to the stopping water on the outer lid 500 to the inside of inlayer lid 600 flows, improves automatically controlled box 200's waterproof performance, and the water that reduces external environment falls into the inside condition emergence of automatically controlled box 200, and then can avoid the inside electrically controlled part of automatically controlled box 200 to wet the damage.

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

Specifically, the case body 210 of the electrical control box 200 actually has an inner layer portion and an outer layer portion; the inner layer part comprises an inner layer bottom plate 400 and an inner layer box cover 600, and the inner layer part (namely the inner layer bottom plate 400 and the inner layer box cover 600) is made of plastic materials, so that the inner layer part is convenient to manufacture and form, and the manufacturing cost is low. 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 and can play a role in fire prevention and rust prevention, so that the electric control box 200 has high safety performance. The water blocking member 611 is integrated with the inner case cover 600, so that the manufacturing process can be additionally increased, and the production efficiency can be improved.

Referring to fig. 4, 6 and 7, in an embodiment, the water blocking member 611 may be a water blocking plate, a water blocking rib, a water blocking flange, or other structures capable of blocking water. Specifically, the inner case cover 600 has an upper cover plate 610, the upper cover plate 610 corresponds to the top wall of the outer case cover 500, and a flange is extended from the outer side of the upper cover plate 610 to the outer side of the outer case cover 500, and the flange forms the water blocking member 611. Specifically, the side of the water blocking member 611 abuts against the upper edge of the outer cover 500, so that the gap between the outer cover 500 and the water blocking member 611 can be reduced.

When water in the external environment falls on the top of the outer box cover 500, the water is not easy to permeate into the gap between the outer box cover 500 and the water blocking member 611, and can only be drained downwards from the side or the back of the outer box cover 500. Of course, in addition to the water blocking member 611 formed at the upper cover plate 610, the water blocking member 611 may be formed at other edges (e.g., left and right side plates) of the inner cover 600. Only in view of the characteristic that water flows from the top to the bottom, water is not easy to permeate into the inner case cover 600 from both sides of the outer case cover 500, so that the water blocking member 611 may not be required to be constructed at both left and right side edges of the inner case cover 600.

Referring to fig. 4, fig. 6 and fig. 7, in an 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 connecting member to pass through to connect and fix the box body 210 with an external structure. After the connector passes through the mounting hole, the inner end of the connector is located between the outer box cover 500 and the inner box cover 600, and if the connector is loosened from the mounting hole, water falling on the outer box cover 500 may also fall onto the inner box cover 600 along the connector from the mounting hole. In view of this, a drain groove 640 corresponding to the mounting hole is formed at the top of the inner cover 600, and the drain groove 640 receives water falling from the mounting hole onto the inner cover 600.

Referring to fig. 6, 12 and 13, considering that the space between the outer box cover 500 and the water blocking member 611 is not completely sealed, when the amount of water falling on the outer box cover 500 is large, the water may be accumulated between the outer box cover 500 and the inner box cover 600 from the gap between the outer box cover 500 and the water blocking member 611. To avoid this, the upper cover plate 610 of the inner cover 600 may be optionally inclined toward the drain groove 640 from the outside of the inner cover 600 to the inside thereof. That is, an angle α (see fig. 14) is formed between the upper cover plate 610 and the horizontal plane, so that the water penetrating through the gap between the outer cover plate 500 and the water blocking member 611 flows into the water drainage groove 640 along the inclined direction of the upper cover plate 610, and is drained downward from the water drainage groove 640 through the back surface of the inner cover 212.

Optionally, a plurality of supporting rib plates 641 are protruded from the top of the inner box cover 600, and a plurality of supporting rib plates 641 are adapted to support the top wall of the outer box cover 500, wherein the drainage groove 640 is formed between two adjacent rib plates. Specifically, a plurality of the support rib plates 641 are coupled to support the top wall of the outer case cover 500 to prevent the top wall of the outer case cover 500 from collapsing downward. A groove is formed between two adjacent support rib plates 641, and one end of the groove is open toward the back of the inner box cover 212, so that the groove can be used as the drainage groove 640, and water supplied into the drainage groove 640 is drained downward toward the back of the inner box cover 212. Of course, in other embodiments, the top of the inner cover 600 may be directly recessed,

referring to fig. 6, 12 and 13, in one embodiment, in order to prevent water from accumulating in the drainage grooves 640, drainage grooves 650 extending in the vertical direction are formed in the back of the inner box cover 600, the upper ends of the drainage grooves 650 are in butt joint with the drainage grooves 640, and the lower ends of the drainage grooves 650 extend to the bottom of the inner box cover 600. By adopting the design, water in the drainage groove 640 flows downwards along the drainage groove 650 and is finally drained from the gap at the bottom of the box body 210, so that the water is prevented from being accumulated in the box body 210.

For the water entering of convenient water drainage tank 640 drainage tank 650, optionally, the upper end of drainage tank 650 is the throat form setting from the top down, can make like this the upper end of drainage tank 650 is less to the resistance of rivers, and the water of water drainage tank 640 is in under the guide of the upper end throat of drainage tank 650, can enter into drainage tank 650 smoothly, reduce rivers and splash.

Referring to fig. 7, 8 and 12, according to any of the above embodiments, in consideration of water splashed on the bottom plate 211 from the external environment, it is also possible to enter the interior of the electrical control box 200 from the assembly gap between the bottom plate 211 and the box cover 212. To reduce this, optionally, the inner box cover 600 has a first side plate 620 and a second side plate 630 which are opposite to each other, and a slot 660 is formed in the inner box cover 600, the slot 660 extends from the first side plate 620 to the second side plate 630 through the upper cover plate 610, and two ends of the slot 660 are open downward; the base plate 211 includes an outer base plate 300 and an inner base plate 400, and the inner base plate 400 is configured at the periphery thereof with insertion portions 420 corresponding to the insertion grooves 660 (as shown in fig. 12 and 13).

When the case body 210 of the electrical control case 200 is assembled, the insertion portion 420 of the bottom plate 211 is correspondingly inserted into the insertion groove 660 of the inner case cover 600, so that the inner case cover 600 covers the bottom plate 211. Owing to with automatically controlled box 200 along vertical arrangement to make slot 660's both ends opening down, if the external environment splash from the assembly clearance between bottom plate 211 and the lid 212, then can enter into the slot 660 of inlayer lid 600 earlier, then along slot 660 to its opening at both ends discharge down, improve automatically controlled box 200's waterproof performance greatly.

Referring to fig. 12 and 15, the insertion part 420 has an upper surface corresponding to the upper cover plate 610 of the inner case cover 600, and the upper surface of the insertion part 420 is inclined downward from the inner side of the inner case cover 600 to the outer side thereof. That is, the upper surface of the insertion part 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 part 420, the water is discharged along the upper surface of the insertion part 420 toward the outside and downward when contacting the upper surface of the insertion part 420, and is difficult to enter the insertion groove 660.

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

Specifically, the sealing strip 430 is made of an elastic waterproof material such as rubber or silicone. When the sealing strip 430 abuts against the inner surface of the slot 660, the sealing strip 430 can be elastically deformed so as to tightly abut against the inner surface of the slot 660, so that a gap between the slot 660 and the insertion part 420 can be reduced, and the possibility of water permeation from the gap can be reduced.

Furthermore, a positioning protrusion 661 may be protruded from an inner surface of the insertion groove 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 against 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, the sealing strip 430 is abutted against the positioning protrusion 661 more tightly, and the sealing effect is better.

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

Referring to fig. 9, 10 and 16, it is considered that the electronic control board 220 generates a large amount of heat during the operation of the electronic control box 200, and if the heat is not exhausted outside in time, the temperature inside the electronic control box 200 is 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, the inner bottom plate 400 is hollowed out at a position corresponding to the electric control board 220, so that a heat dissipation area is formed between the electric control board 220 and the outer bottom plate 300.

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

The grid support 440 is formed at the hollowed-out position 410 of the inner bottom plate 400, the grid support 440 is suitable for separating the outer bottom plate 300, and the outer bottom plate 300 can be prevented from being contacted with the electric control board due to the fact that external extrusion force is applied to the outer bottom plate 300 and the hollowed-out position 410 is sunken, so that overheating of the outer bottom plate 300 can be avoided, the electric control board 220 is prevented from being leaked through the outer bottom plate 300, and safety performance of the electric control box 200 is improved.

Referring to fig. 16 and 17, based on the above embodiment, the distance between the electric control board 220 and the outer base board 300 is theoretically determined (e.g. D in fig. 17)₂Shown) is larger, the more favorable the heat dissipation; however, the space inside the electrical control box 200 is also occupied, so that the overall volume of the electrical control box 200 is increased. Therefore, the spacing between the electronic control board 220 and the outer floor 300 should be maintained within a certain range.

The research shows that when the distance between the electric control board 220 and the outer bottom board 300 is not less than 8mm and not more than 18mm, a larger gap can be obtained between the electric control board 220 and the outer bottom board 300, so that the electric control box has better heat dissipation efficiency and safety performance, and the space occupied by the electric control box 200 is smaller, so that the whole volume of the electric control box 200 can still be kept smaller. Accordingly, the spacing between the electronic control board 220 and the outer floor 300 may be selected to be no less than 8mm, and no greater than 18 mm. Such as but not limited to: 8mm, 10mm, 12mm, 15mm, 16mm, 17mm, and the like. The electronic control board 220 may be designed accordingly according to the size thereof, and is not particularly limited 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 sidewall of the main cavity 601 and the outer box cover 500 at an interval, and a heat dissipation hole 680 corresponding to the heat dissipation gap is further formed through the sidewall of the main cavity 601. The plurality of heat dissipation holes 680 are arranged at intervals in the vertical direction. The heat in the main cavity 601 can be dissipated to the gap between the inner box cover 600 and the outer box cover 500 through the plurality of heat dissipating holes 680, and then dissipated outwards through the outer box cover 500.

It is considered that moisture in the external environment may penetrate into the interior through a gap (e.g., a gap between the outer bottom plate 300 and the outer box cover 500, or a gap at a connecting position of the electronic control box 200 and the housing of the product to which the electronic control box is applied) on the box body 210, and then enter the main cavity 601 through the heat dissipation holes 680, so that the electronic control board 220 may be affected by moisture and fail.

In order to avoid this situation, a water blocking fence 681 may be protruded at the periphery of the heat dissipation hole 680, where the water blocking fence 681 surrounds the heat dissipation hole 680, and the water blocking fence 681 is inclined from the inside of the heat dissipation hole 680 to the outside thereof. Therefore, when the side wall of the main cavity 601 in the external environment is covered and guided by the water blocking fence 681, the water drops sequentially and downwardly (the dotted arrow in fig. 6 indicates the drainage direction), and then the water drops flow to the bottom of the box 210, and finally the water drops are 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 from the heat dissipation holes 680, and the occurrence of faults caused by the fact that the electric control board 220 is affected with damp is reduced.

Referring to fig. 6, 8 and 17, in an embodiment, the electrical control box 200 further includes a heat sink 240 mounted on the electrical 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 port 603 for the radiator 240 to extend outwards, a sinking groove 690 is formed on the inner circumference of the extension port 603, and the sinking groove 690 is embedded in the sealing sleeve 250 correspondingly.

Specifically, the heat sink 240 includes a base 241 and a plurality of heat dissipation fins 242 configured on the base 241, and the base 241 is mounted on the electronic control board 220. The sealing sleeve 250 is sleeved on the base plate 241. After the electronic control box 200 is assembled, the heat dissipation fins 242 of the heat sink 240 extend outward from the extension opening 603, and the sealing sleeve 250 is inserted into the sinking groove 690, so that the sealing sleeve 250 is used to seal the gap between the extension opening 603 and the periphery of the heat sink 240, and water in the external environment is prevented from permeating into the electronic control box 200 from the gap.

With reference to fig. 8, fig. 6 and fig. 17, further, a plurality of annular ribs 691 are protruded from a surface of the sink 690, the plurality of annular ribs 691 sequentially surround the periphery of the protruding port 603, and the annular ribs 691 abut against the surface of the sealing sleeve 250. The plurality of annular convex ribs 691 are abutted against the surface of the sealing sleeve 250, so that under the pressing action force of the annular convex ribs 691, the surface of the sealing sleeve 250 is elastically deformed, and the annular convex ribs 691 are abutted more tightly, so that the gap between the radiator 240 and the periphery of the extension opening 603 can be effectively reduced, the condition that external water permeates into the interior of 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 plurality of annular ribs 691 are arranged along the periphery of the extension opening 603 in a zigzag manner, and the plurality of annular ribs 691 are matched and abutted against the surface of the sealing sleeve 250, so that multi-layer sealing is formed on the periphery of the radiator 240, and the sealing and waterproof effects are greatly improved. The annular rib 691 may be arranged in a regular or irregular annular shape. For example, but not limited to, the annular bead 691 may be of polygonal (e.g., square, trapezoidal, pentagonal, etc.) design, or may be of circular design, or may be of oval design, etc. In practical applications, the annular rib 691 is preferably consistent with the protruding opening 603, and may be designed accordingly 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 type air conditioner 100, wherein the window type air conditioner 100 includes a base plate 110, a casing 120, an outdoor fan 160 and an electric control box 200. The specific structure of the electrical control box 200 refers to the above embodiments, and since the window air conditioner 100 adopts all technical solutions of all the above embodiments, all the beneficial effects brought by the technical solutions of the above embodiments are also achieved, and no further description is given here.

Referring to fig. 1 to 3, in an embodiment, the housing 120 is mounted on the chassis 110, the housing 120 includes an outdoor side housing 122 and an indoor side housing 121, and a ceiling of the outdoor side housing 122 is provided with an outdoor side air inlet 170; the outdoor fan 160 is installed in the outdoor side housing 122; the electric control box 200 is mounted on the outdoor side housing 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 air inlet 170 has an air inlet side 171 far away from the outdoor fan 160, the cover 212 of the electronic 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, which is opposite to the outdoor air inlet 170. Therefore, the water falling from the outdoor air inlet 170 onto the lid 212 of the electronic control box 200 is blocked by the water blocking member 611, and can only be drained downward from the back of the lid 212, and is difficult to cross the water blocking member 611 and fall onto the assembly position between the lid 212 and the bottom plate 211, and is difficult to penetrate into the electronic control box 200.

It is considered that when water in the external environment falls from the outdoor air inlet 170 to the lid 212 of the electronic control box 200, water drops collide with the top wall of the outer lid 500 to splash water drops in the circumferential direction, and the splashed water drops may cross the water blocking member 611. Therefore, in order to avoid splashed water droplets from 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 6 mm.

Referring to fig. 12 to 14, a dotted arrow in fig. 14 indicates a drainage direction, D₁Indicated as the distance between said water deflector 611 and said tuyere side 171, i.e. with D₁Not less than 6 mm. The radius of the splashed water droplets to spread all around is typically less than 6 mm. Therefore, by defining the distance between the water blocking member 611 and the tuyere side 171 to be not less than 6mm, it is possible to allow the splashed water drops to fall again onto the top wall of the outer cover 500 without crossing the water blocking member 611, and then to flow and drain from the top wall of the outer cover 500 toward the rear thereof.

Of course, the distance between the water blocking member 611 and the tuyere side 171 is not larger, and the larger the distance is, the larger the space occupied by the electric control box 200 is, which is not favorable for saving the installation space. It is defined herein that the distance between the water-blocking member 611 and the tuyere side 171 is not more than 50mm, i.e., 6 mm. ltoreq.D₁≤50mm。D₁May be, but is not limited to: 6mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 48mm, etc.

Specifically, by defining 6 mm. ltoreq.D₁Less than or equal to 50mm, the splashed water drops are ensured to be difficult to cross the water blocking piece 611, the space occupied by the control box is small, and the control box 200 is convenient to be installed in the narrow space on the air inlet side of the outdoor fan 160. It should be noted that the side 171 of the tuyere may be a straight edge or a non-straight edge; when the tuyere rear side edge is a non-straight edge, the distance between the aforementioned water blocking member 611 and the tuyere side edge 171 should refer to a minimum distance between the water blocking member 611 and the tuyere side edge 171.

It is considered that, if the electrical control box 200 is only connected and fixed to the chassis 110 through the bottom thereof, and the top of the electrical control box 200 is not fixed, during the transportation and transfer of the window air conditioner 100, the electrical 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), so that the fireproof or antirust coating on the surface of the electrical control box 200 may be scratched and fail, thereby causing a great safety hazard.

In one embodiment, to reduce the above-mentioned situation, the top plate of the outdoor casing 122 is provided with a fixing portion 180, and the fixing portion 180 is adapted to be connected and fixed with a mounting portion 510 at the top of the electrical control box 200 by a connecting member. Specifically, the fixing portion 180 is formed with a through hole, the mounting portion 510 is formed with a docking hole, and the electrical control box 200 and the outdoor side housing 122 are connected and fixed by a connecting member sequentially passing through the through hole and the docking hole. Wherein the connecting member may be a screw. The mounting portion 510 protrudes from the top surface of the electrical control box 200, so that the penetration of extra water from the mating hole of the mounting portion 510 into the interior of the electrical control box 200 can be reduced.

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

Referring to fig. 1 and 21, in an embodiment, the housing 120 is mounted on the chassis 110, a separation groove 123 for a shielding member at the window to extend into is formed on the housing 120, and the housing 120 is separated into an indoor side housing 121 and an outdoor side housing 122 by the separation groove 123; the outdoor fan 160 is installed in the outdoor side housing 122; the electronic control box 200 is installed in the outdoor side housing 122, the electronic control box 200 is vertically disposed, and the heat sink 240 of the electronic control box 200 faces the outdoor fan 160.

In particular, the slot 123 is adapted to receive a screen at a window in a wall. After the window type air conditioner 100 is installed on the window of the wall, the outdoor side box cover 212 is located outdoors, and the indoor side box cover 212 is located indoors, so that noise generated by the outdoor side part can be prevented from being transmitted to the indoor side, and the noise reduction effect is achieved. Then, the shielding member is pulled down to extend into the separating groove 123 of the window type air conditioner 100, and the shielding member shields the gap between the two sides of the window type air conditioner 100 and the side wall 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 element may be a window sash, a louver, a curtain, or the like, which can shield light, or may be other shielding window panels, which can shield external objects from entering the room.

The window type 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 housing 121; an outdoor heat exchanger 140 and an outdoor fan 160 are installed in the outdoor side case 122. When the window air conditioner 100 operates, the indoor fan 150 drives indoor air to enter the indoor side housing 121 to exchange heat with the indoor heat exchanger 130, and blows out the heat-exchanged air from the indoor side housing 121 to the indoor environment, thereby cooling and heating the indoor environment. Meanwhile, the outdoor fan 160 drives outdoor air into the outdoor side housing 122 to exchange heat with the outdoor heat exchanger 140, and blows out the heat-exchanged air from the outdoor side housing 122 to the outdoor environment. The electrical control box 200 is vertically installed in the outdoor side housing 122, and the electrical control box 200 is located at the air inlet side of the outdoor fan 160, so that when the window type air conditioner 100 works, the airflow driven by the outdoor fan 160 passes around the electrical control box 200, and a part of heat generated by the electrical control box 200 is taken away.

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

After the window type air conditioner 100 is installed in the window, the sealing member 700 is moved to the working state, so that the sealing member 700 laterally extends out from the separation groove 123 of the window type air conditioner 100, and the bottom surface of the sealing member 700 abuts against the bottom wall of the window; then, the shielding member is pulled down to extend into the separating groove 123 of the window type air conditioner 100 until the lower edge of the shielding member contacts and abuts against the separating member and the sealing member 700, and the sealing member 700 shields and seals the gap between the shielding member and the bottom wall of the window so far, so that the leakage of indoor cold or heat from the gap to the outside is reduced. When the window type air conditioner 100 is not needed or is 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 type air conditioner 100 can be conveniently stored or packaged.

There are various ways of removably mounting the seal 700. For example, the seal 700 is slidably mounted on the separation groove 123; alternatively, the sealing member 700 is rotatably installed to the separation groove 123; alternatively, the sealing member 700 may be elastically and telescopically mounted to the separation groove 123. Specifically, the seal member 700 is rotatably mounted to the separation groove 123 to be switched between the operating state and the storage state by rotation.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
