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 electronic control box 200 is vertically installed on the outdoor side housing 122, and the electronic control box 200 is located on the air inlet side of the outdoor fan 160 and is arranged side by side with the compressor 170 of the air conditioner 100. Therefore, one end of the electrical control box 200 is close to the compressor 170, which is narrow and not easy to install. Therefore, the pre-positioning member 610 can be constructed at one end of the electronic control box 200 close to the compressor 170, and the pre-positioning member 610 can be inserted and connected with the insertion part 111 of the chassis 110, so that the screwing operation is not needed, and the operation is simple and easy.

When the electronic control box 200 is installed, the predetermined position member 610 of the electronic control box 200 is inserted into the insertion portion 111 of the chassis 110, so that the electronic control box 200 is positioned on the chassis 110, and then the fixing structure of the electronic control box 200 is connected and fixed with the chassis 110. That is to say, the location is planted earlier to automatically controlled box 200 for automatically controlled box 200 is difficult for the activity, makes things convenient for follow-up fixed operation of automatically controlled box 200, and the installation degree of difficulty is lower, and the operation of being extremely convenient for is favorable to improving the installation effectiveness.

The technical scheme of the utility model, through bottom construction preposition piece 610 and fixed knot at automatically controlled box 200 to construct the insertion portion 111 that corresponds with preposition piece 610 on chassis 110, thereby when the automatically controlled box 200 of installation, can insert the connection with the insertion portion 111 of chassis 110 through preposition piece 610 with automatically controlled box 200 earlier, realize automatically controlled box 200 preposition, then the rethread fixed knot constructs and is connected fixedly with chassis 110. Therefore, the utility model discloses an air conditioner 100 earlier plants the location with automatically controlled box 200 earlier for automatically controlled box 200 is difficult for the activity, and the fixed operation of convenient follow-up automatically controlled box 200, the installation degree of difficulty is lower, is favorable to improving the installation effectiveness.

Referring to fig. 6, 8 and 9, in an embodiment, the electrical control box 200 includes a box body 210, the box body 210 includes a bottom plate 211 and a box cover 212 adapted to cover the bottom plate 211, the bottom plate 211 includes an outer metal bottom plate 300 and an inner plastic bottom plate 400, and the box cover 212 includes an outer metal box cover 500 and an inner metal box cover 500; the pre-positioning member 610 is configured on the inner plastic bottom plate 400 or the inner plastic box cover 600.

Specifically, the outer metal base plate 300 and the inner plastic base plate 400 of the base plate 211 are fixed into a whole through a snap structure or a screw structure; the outer layer metal box cover 500 and the inner layer metal box cover 500 of the box cover 212 can also be fixed together by a buckle structure or a screw structure. That is, the body 210 of the electrical control box 200 actually has an inner portion and an outer portion; wherein, the inner part is composed of the inner layer plastic bottom board 400 and the inner layer plastic box cover 600; the outer layer part is composed of the outer layer metal bottom plate 300 and the outer layer metal box cover 500. The outer layer part can be made of antirust sheet metal parts.

The pre-positioning member 610 is herein constructed at the inner portion (i.e., the lower end of the inner plastic bottom panel 400 or the lower end of the inner plastic lid 600) for two reasons. One aspect of the method is as follows: the inner layer part directly receives the heat emitted by the electric control element in the electric control box 200, and the inner layer part can be directly conducted to the pre-positioning piece 610, so that indirect heat transfer through the outer layer part is not needed, and the heat dissipation is rapid. On the other hand: the inner layer is made of plastic, so that the cost is low and the forming is easy, and the pre-positioning piece 610 and the inner layer are conveniently formed integrally.

Referring to fig. 6, 8 and 9, the air conditioner 100 further includes a compressor 170 disposed in parallel with the electrical control box 200, one end of the bottom of the box body 210 near the compressor 170 is disposed in a notch to form a notch, and the pre-positioning element 610 extends downward from the inner plastic bottom plate 400 or the inner plastic box cover 600 to one side of the notch.

Specifically, the top wall or the side wall of the notch is provided with a wire passing hole, and a wire inside the electronic control box 200 passes through the wire passing hole to the notch position, and then is drawn from the notch to an electronic control component (such as a display panel, or an outdoor temperature sensor, or an indoor temperature sensor, or an exhaust or return temperature sensor of the compressor 170) of the air conditioner 100. Since the pre-positioning member 610 is directly inserted into the insertion portion 111 of the chassis 110, it is not necessary for a user to manually perform a connection operation (e.g., screwing) at the position, and therefore, the pre-positioning member 610 is configured at one side of the notch, so that the space of the notch can be reasonably utilized, the extra occupied space of the components can be reduced, and the volume of the electronic control box 200 can be further reduced.

Referring to fig. 5 to 7, the specific assembling structure of the predetermined position element 610 of the electronic control box 200 and the inserting portion 111 of the chassis 110 is not limited in detail. Optionally, the pre-positioning member 610 includes a positioning frame 611 connected to the case 210 of the electronic control box 200, and a plug board 612 configured at a lower end of the positioning frame 611 and protruding laterally; the insertion portion 111 of the chassis 110 is configured with insertion holes adapted for the corresponding insertion of the insertion plate 612.

Specifically, the positioning frame 611 is configured with a heat dissipation channel 631, and a portion of heat generated inside the electronic control box 200 can be directly conducted to the pre-positioning member 610 and then dissipated to the outside through the heat dissipation channel 631 on the positioning frame 611. The insertion plate 612 is configured at the lower end of the positioning frame 611 to be inserted into the insertion hole on the insertion portion 111 of the chassis 110.

In order to facilitate the corresponding insertion of the insertion plate 612 and the insertion hole, the insertion hole of the insertion portion 111 may be arranged in a flared shape, so that the resistance of the insertion hole to the insertion plate 612 is small; the upper edge of the insertion hole is also obliquely extended upwards to form a guide flange 112, and the insertion plate 612 is guided into the insertion hole by the guide flange 112, so that the difficulty of inserting the insertion plate 612 and the insertion part 111 is greatly reduced.

Referring to fig. 5 to 7, in an embodiment, after the inserting plate 612 of the pre-positioning member 610 is inserted into the inserting portion 111, the upper surface of the inserting plate 612 abuts against the top wall of the inserting hole, and the connecting position between the inserting plate 612 and the positioning frame 611 is stressed strongly, and may be broken at the connecting position. To avoid this, optionally, the pre-positioning member 610 is further configured with a connecting rib 613, and the connecting rib 613 includes a first rib 6131 extending from the side surface of the positioning frame 611 along the vertical direction, and a second rib 6132 extending from the lower end of the first rib 6131 to the upper surface of the inserting plate 612.

Specifically, the connection between the first rib 6131 and the second rib 6132 of the connecting rib 613, i.e., the connection between the positioning frame 611 and the inserting plate 612, helps to improve the strength of the connection between the inserting plate 612 and the positioning frame 611, so that the connection is not easily broken. On the other hand, after the cartridge body 210 of the electronic control cartridge 200 is integrally manufactured, if the insertion plate 612 of the pre-positioning element 610 is not matched with the insertion portion 111 of the chassis 110, the insertion plate 612 of the pre-positioning element 610 can be matched with the insertion portion 111 of the chassis 110 by cutting the protruding height of the connecting rib 613, and the whole cartridge body 210 of the electronic control cartridge 200 does not need to be modified, so that the rework procedure is reduced, and the production efficiency is improved.

Referring to fig. 5 to 7, further, in order to reduce the difficulty of inserting the insertion plate 612 and the insertion portion 111, a guide inclined surface 615 may be configured on an upper surface of the insertion end of the insertion plate 612 and/or the insertion end of the second rib 6132, and the guide inclined surface 615 is inclined from top to bottom along the insertion direction. This reduces the resistance of the insertion end of the plugboard 612, so that the insertion end of the plugboard 612 can be smoothly inserted into the jack.

In addition, a transverse rib 614 is further configured on the upper surface of the insertion plate 612, the transverse rib 614 and the second rib 6132 are arranged in a criss-cross manner, and the transverse rib 614 is suitable for abutting against the upper wall surface of the insertion hole for positioning. The transverse ribs 614 may increase the strength of the pinboard 612, so that the pinboard 612 is not easily bent and deformed. Similar to one of the above-mentioned connecting ribs 613, after the cartridge body 210 of the electronic control cartridge 200 is integrally manufactured, if the insertion plate 612 of the pre-positioning element 610 is not matched with the insertion portion 111 of the chassis 110, the insertion plate 612 of the pre-positioning element 610 can be matched with the insertion portion 111 of the chassis 110 by cutting the protruding height of the transverse rib 614, without modifying the whole cartridge body 210 of the electronic control cartridge 200, thereby reducing the rework procedure and contributing to improving the production efficiency.

Referring to fig. 3, 4 and 8, the fixing structure of the electrical control box 200 and the specific assembling structure of the chassis 110 are not specifically limited herein. Optionally, the fixing structure includes a fixing plate 310 configured on the outer metal box cover 500 and a fixing leg 620 configured on the inner plastic bottom plate 400, and the fixing plate 310 and the fixing leg 620 are oppositely disposed and are respectively connected and fixed with the chassis 110.

Specifically, the fixing plate 310 is integrally formed with the outer lid 500 and extends laterally from the lower end of the outer lid 500 to be connected and fixed with the chassis 110 by a connector. The ground member of the electronic control box 200 may be mounted to the outer metal box cover 500 and then grounded through the fixing plate 310 connected to the outer metal box cover 500. The fixing legs 620 are integrally formed with the inner plastic base 400, and heat generated by the electric control elements inside the electric control box 200 can be directly transmitted to the supporting members 630 from the inner plastic base 400 and then dissipated outwards through the supporting members 630. A first projection 613 and a second projection 614 are formed on the base plate 110. The fixing plate 310 and the first protrusion 613 are connected by a connector. The fixing leg 620 is connected with the second protrusion 614 by a connecting member. The attachment means may be a screw.

After the electrical control box 200 is fixed by the pre-positioning member 610, one end of the electrical control box 200, which is far away from the pre-positioning member 610, is close to the side wall of the chassis 110, so that the space between the electrical control box 200 and the side wall of the chassis 110 is small, and it is inconvenient for a user to insert a hand into the electrical control box 200 to perform operations such as fixing. Therefore, the fixing plate 310 and the fixing leg 620 are respectively disposed at two opposite sides of the electrical control box 200, so that after the electrical control box 200 is fixed by the pre-positioning member 610, the space at two sides of the electrical control box 200 is large without being interfered by the side wall of the chassis 110, and there is enough space for connecting and fixing the fixing plate 310 or the fixing leg 620 with the chassis 110.

Referring to fig. 10, in an embodiment, a support 630 is further configured at the bottom of the electrical control box 200, the support 630 is adapted to support the electrical control box 200, and a plurality of heat dissipation channels 631 are configured on the support 630. The supporting member 630 is integrally connected to the fixing leg 620, the supporting member 630 includes a plurality of supporting plates extending downward from the bottom wall of the electronic control box 200, and a heat dissipating channel 631 is formed between two adjacent supporting plates at an interval.

Specifically, the plurality of support plates cooperatively support the electrical control box 200, and the support plates form heat dissipation surfaces at opposite sides thereof, so that the support member 630 has a large heat dissipation area. When the air flow passes through the heat dissipation channel 631, the air flow takes away the heat conducted from the electronic control box 200 to the heat dissipation surface of the support plate, and the heat dissipation effect is good.

Referring to fig. 12 to 14, based on any of the above embodiments, the electrical control box 200 further includes an electrical control board 220, the electrical control board 220 is mounted on the inner plastic bottom board 400, the inner plastic box cover 600 is configured with a main cavity 601, and the main cavity 601 is suitable for accommodating components on the electrical control board 220. Specifically, the electric control board 220 is mounted on the inner plastic base board 400, the inner plastic base board 400 is hollowed out at a position corresponding to the electric control board 220, a grid bracket 420 is formed at the hollowed-out position 410, and the electric control board 220 and the outer metal base board 300 are separated by the grid bracket 420, so that a heat dissipation area is formed between the electric control board 220 and the outer metal base board 300.

Please refer to fig. 15, D in fig. 15₁Shown as the spacing between the electrical control board 220 and the outer metal chassis 300. Theoretically, the larger the distance between the electric control board 220 and the outer metal bottom board 300 is, the more favorable the air flow circulation is, and the more favorable the heat dissipation is; however, the space of the electronic control box 200 is also occupied correspondingly, so that the overall volume of the electronic control box 200 is increased. Therefore, the spacing between the electronic control board 220 and the outer metal chassis 300 should be maintained within a certain range. The research shows that when the distance between the electric control board 220 and the outer metal 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 metal bottom board 300, the space occupied by the electric control box 200 is smaller, and the whole volume of the electric control box 200 can still be kept smaller.

In view of this, the distance between the electric control board 220 and the outer metal base plate 300 may be selected to be not less than 8mm, and not more 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. 10 and 11, in an embodiment, considering that the main heat source of the electronic control box 200 is from the electronic control board 220, and the components on the electronic control board 220 are accommodated in the main cavity 601 of the inner plastic box cover 600, the heat transfer efficiency of the inner plastic box cover 600 is low, which is not favorable for heat dissipation. Therefore, a plurality of heat dissipation holes 640 may be formed through the inner plastic box cover 600 on the sidewall corresponding to the main cavity 601, and the heat dissipation holes 640 are arranged at intervals in the vertical direction. The heat in the main cavity 601 can be dissipated to the gap between the inner plastic box cover 600 and the outer metal box cover 500 through the plurality of heat dissipating holes 640, and then dissipated outwards through the outer metal 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 metal bottom plate 300 and the outer metal lid 500, or a gap at a connection position between the top of the box body 210 and the product housing) on the box body 210, and then enter the main cavity 601 through the heat dissipation holes 640, so that the electronic control board 220 may be affected by moisture and fail.

Referring to fig. 10 and 11, to avoid this situation, a water baffle 641 may be protruded laterally on the periphery of the heat dissipation hole 640, and the water baffle 641 surrounds the heat dissipation hole 640. The water baffle 641 is disposed to be inclined downward from the inner side of the heat dissipation hole 640 to the outer side thereof. Therefore, when on the lateral wall of the main cavity 601 of water in the external environment, sheltered and guided by the water-retaining bounding wall 641 and drop downwards in turn, and then flow to the bottom of the box 210, and finally discharge to the chassis 110 from the gap at the bottom of the box 210, thereby avoiding the water drop from entering into the main cavity 601 from the heat dissipation hole 640, and reducing the occurrence of the trouble caused by the damp of the electric control board 220.

Referring to fig. 12 and 15, in an embodiment, the electronic control box 200 further includes a reactor 230, and the reactor 230 is fixed on the outer metal base plate 300 through the inner plastic base plate 400; the inner plastic cover 600 is configured with a secondary cavity 602, and the secondary cavity 602 is suitable for accommodating the reactor 230. The outer metal base plate 300 is made of a sheet metal part, so that the outer metal base plate 300 has higher strength and is not easy to bend and deform compared with the inner plastic base plate 400. Therefore, the reactor 230 is fixed to the outer-layer metal base plate 300 so that the reactor 230 can be strongly supported by the outer-layer metal base plate 300, and the outer-layer metal base plate 300 is less likely to be deformed.

Further, in order to enhance the stability of the reactor 230 in mounting, the outer metal base plate 300 is partially recessed from its outer wall surface toward its inner wall surface, a mounting boss 320 for the reactor 230 is formed inside the recessed position, and a sinking groove 330 is formed outside the recessed position, the sinking groove 330 being adapted to receive the connecting member 40 of the reactor 230 or the ground member 50 of the electrical control box 200. That is, after the connecting member 40 fixing the reactor 230 passes through the mounting boss 320, the outer end of the connecting member 40 is received in the sink 330 and does not protrude from the outer wall surface of the case 210, so that the operator or the cabinet 120 of the air conditioner 100 is not easily scratched.

In addition, the electronic control board 220 needs to be grounded through the grounding member 50, and the grounding member 50 (e.g., a grounding screw) may be mounted on the outer metal base plate 300 to be grounded through the outer metal base plate 300 (see fig. 8). Similarly, to avoid the outer end of the grounding member from scratching the operator or the cabinet 120 of the air conditioner 100, the grounding member is also mounted to the mounting boss 320. The sink 330 is also adapted to receive the grounding member 50.

Referring to fig. 6, 9 and 17, in an embodiment, the electrical control box 200 further includes a heat sink 240, the heat sink 240 is mounted at one end of the electrical control board 220 and is located above the reactor 230, an accommodating groove 510 is formed on an outer wall surface of the outer metal box cover 500 at a position of the heat sink 240, and an extending opening 650 is formed on a wall surface of the accommodating groove 510 for the heat sink 240 to extend to the accommodating groove 510. After the heat sink 240 is mounted, the heat sink 240 extends from the interior of the box body 210 to the accommodating groove 510 through the extending opening 650, so that the heat sink 240 does not protrude from the outside of the whole electronic control box 200, and the heat sink 240 is exposed outside the electronic control box 200, thereby effectively dissipating heat generated by the electronic control board 220 to the outside of the box body 210.

Referring to fig. 15 and 16, further, a sealing sleeve 250 is disposed around the heat sink 240, a plurality of annular ribs 651 are disposed on an inner circumference of the extension 650 of the box cover 212, and the plurality of annular ribs 651 are adapted to abut against a surface of the sealing sleeve 250. The sealing sleeve 250 and the box cover 212 are tightly pressed by the abutting of the plurality of annular convex ribs 651 and the surface of the sealing sleeve 250, so that a gap between the extension port 650 of the box cover 212 and the periphery of the radiator 240 is sealed, external water is prevented from falling into the box body 210 from the gap, and the occurrence of faults caused by the fact that the electric control board 220 is affected with damp is reduced.

In the process of manufacturing and molding on the box body 210, due to the difficulty of mold manufacturing, a groove wall is not easily formed at the bottom position of the outer layer metal box cover 500 corresponding to the accommodating groove 510, but the outer layer metal box cover 500 is formed with an opening 520 at the bottom position corresponding to the accommodating groove 510, if the opening 520 is directly opened, the top of the auxiliary cavity 602 of the inner layer plastic box cover 600 is exposed in the external environment, and the requirement of safety regulations is not met.

In view of this, the electrical control box 200 further comprises a metal cover plate 260 configured to cover the opening 520, the metal cover plate 260 being adapted to cover the reactor 230. The metal cover 260 may be made of sheet metal. The metal cover plate 260 has better fireproof and antirust performance, so that the reactor 230 can be prevented from being directly exposed in the external environment, and the reactor 230 is protected.

In one embodiment, the case 210 and some of the components of the electrical control box 200 can be fixed as a whole by a plurality of connectors. The plurality of screw members include a first connecting member, a second connecting member and a third connecting member, wherein the first connecting member is located at the upper end of the electronic control box 200 (as shown at position P in fig. 6)₁) An outer metal box cover 500, an inner plastic box cover 600 and an inner plastic bottom plate 400 are sequentially arranged in a penetrating manner to connect the three; the second connecting member is received in the receiving groove 580 (as shown by position P in fig. 6)₂) The upper flange of the metal cover plate 260, the outer metal box cover 500, the inner plastic box cover 600 and the inner plastic bottom plate 400 are sequentially inserted through and connected with each other. The third connecting member sequentially passes through the outer metal box cover 500, the inner plastic box cover 600 and the pre-positioning member 610 to connect the three (as shown in position P in fig. 6)₃)。

Referring to fig. 1 to 3, according to any of the above embodiments, the air conditioner 100 further includes a casing 120 installed on the chassis 110, a partition groove 123 is formed on the casing 120 for a shielding member located at a window of a wall to extend into, and the casing 120 is divided into an indoor side casing 121 and an outdoor side casing 122 by the partition groove 123. The electronic control box 200 is vertically installed at the outdoor side housing 122. Also, the electronic control box 200 is located at the air inlet side of the outdoor fan 160, so that when the air conditioner 100 operates, the air flow driven by the outdoor fan 160 passes around the electronic control box 200, thereby taking away a part of the heat generated by the electronic control box 200.

When the air conditioner 100 is installed on a window of a wall, the outdoor side housing 122 is located outdoors, and the indoor side housing 121 is located indoors, so that noise generated by the outdoor side member can be prevented from being transmitted to the indoor side, and a noise reduction effect can be achieved. Then, the shielding member is pulled down to extend into the separation groove 123 of the air conditioner 100, and shields the gap between both sides of the air conditioner 100 and the side wall of the window, so that the leakage of indoor cooling or heating 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.

It is considered that if the electrical control box 200 is fixed to the chassis 110 only by the pre-positioning member 610 and the fixing structure at the bottom thereof, and the top of the electrical control box 200 is not fixed, during the transportation and transfer of the air conditioner 100, the electrical control box 200 may swing back and forth to collide with the adjacent components (such as the outdoor fan 160 or the fan bracket 180), so that the fireproof or antirust coating on the surface of the electrical control box 200 may be scratched to fail, thereby presenting a great safety hazard.

In one embodiment, in order to reduce the above situation, a first fixing portion 10 is disposed on the top plate of the housing 120 and located above the electronic control box 200, a first abutting portion 11 is protruded from the top of the electronic control box 200, and the first abutting portion 11 and the first fixing portion 10 are connected and fixed through a connecting member.

Specifically, the first fixing portion 10 is formed on the ceiling of the outdoor side housing 122, the first fixing portion 10 is formed with a through hole, the first docking portion 11 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 first docking portion 11 protrudes from the top surface of the electrical control box 200, so that the infiltration of extra water from the docking hole of the first docking portion 11 into the electrical control box 200 can be reduced.

After the top of the electrical control box 200 is connected to the first fixing portion 10 of the outdoor side housing 122 through the first docking portion 11, 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 prone to swing, and thus the occurrence of collision between the electrical control box 200 and its adjacent components can be reduced.

Referring to fig. 1 to fig. 3, in an embodiment, a fan bracket 180 is further disposed in the casing 120, and the fan bracket 180 is suitable for installing the outdoor fan 160. In the related art, the blower bracket 180 is usually fixed to the base plate 110 only through the bottom thereof, and thus the blower bracket 180 may swing back and forth to collide with the electrical control box 200 during the transportation of the transfer air conditioner 100, thereby scratching the fireproof or rustproof coating on the surface of the electrical control box 200.

Therefore, optionally, the top plate of the case 120 is provided with the second fixing part 20 and the third fixing part 30; the top surface of the blower bracket 180 is convexly provided with a second butting part 21 and a third butting part 31, and the second butting part 21 and the second fixing part 20, and the third butting part 31 and the third fixing part 30 are fixedly connected through connecting pieces.

Specifically, the top plate of the outdoor casing 122 is configured with the second fixing portion 20 and the third fixing portion 30, and the first fixing portion 10, the second fixing portion 20 and the third fixing portion 30 are respectively arranged in a triangle, so that after the three parts are respectively butted with the first butting portion 11, the second butting portion 21 and the third butting portion 31, a triangle stable structure is formed, and thus the mounting positions of the outdoor casing 120, the electric control box 200 and the fan bracket 180 are stable and are not easy to shake, and a distance is maintained between the electric control box 200 and the fan bracket 180 (as D in fig. 1)₀Shown), reducing the occurrence of collisions between the two.

Referring to fig. 8 and 10, in the process of fixing the top of the electrical control box 200, after the connecting member passes through the mating hole of the first mating portion 11, the inner end of the connecting member extends into the electrical control box 200. If the connection member and the docking hole are not tightly fitted, water in the external environment may flow down along the connection member into the interior of the electronic control box 200, and the electronic control elements inside the electronic control box 200 may be affected with damp.

In view of this, to avoid this, the inner plastic cover 600 of the electrical control box 200 is provided with a groove 660 corresponding to the first butt joint part 11, and the back of the inner plastic cover 600 is provided with a drainage groove 670 extending downward from the groove 660 to the bottom thereof. The inner end of the connector is correspondingly located in the recess 660 after the connector is passed through the mating hole of the first mating portion 11. Thus, if water flows down the connector into the interior of the electrical control box 200, the water will fall from the inner end of the connector into the groove 660, flow down the drainage groove 670 from the groove 660, and finally drain out of the drainage gap at the bottom of the electrical control box 200.

Specifically, a plurality of support rib plates 690 are convexly arranged on the top surface of the inner plastic box cover 600, and the plurality of support rib plates 690 are supported on the top wall of the outer metal box cover 500, so that the top wall of the outer metal box cover 500 is not easy to collapse downwards. A groove 660 is formed between adjacent two support webs 690. One of the grooves 660 corresponds to the first butting portion 11. One side of the other grooves 660 is open, and if water in the external environment falls into the groove 660 on the top surface of the inner layer plastic box cover 600, the water can flow to the back surface of the inner layer plastic box cover 600 from the opening on one side of the groove 660, so that the water is discharged downwards along the back surface of the inner layer plastic box cover 600. In addition, the plurality of support ribs 690 may also serve to reinforce the strength of the plastic box cover 600.

Referring to fig. 18 and 19, in an embodiment, the 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 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 of the separation groove 123 of the 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 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 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 air conditioner 100 is conveniently stored or packaged.

There are various ways of removably mounting the seal 700. For example, the seal 700 is slidably mounted on the partition; 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.
