[0081] like Figures 4-7As shown, the housing 1 has a first cavity 110 and a second cavity 120. The second cavity 120 is located on one side of the first cavity 110. The first cavity 110 and the second cavity 120 are arranged on the same horizontal plane. The first cavity 110 and the second cavity 120 are spaced apart. The first cavity 110 and the second cavity 120 can be constructed in a roughly rectangular hexahedral shape. The housing 1 has a first air inlet 101, a first air outlet 102, a second air inlet 103, and a second air outlet 104. The first air inlet 101 is located on the side wall of the first cavity 110. The first air inlet 101 communicates with the interior space and is used to supply air into the first cavity 110. The first air outlet 102 is located on the bottom wall of the first cavity 110. The first air outlet 102 can be constructed in a straight strip shape. The first air outlet 102 is used to exit the first cavity 110 from the first air inlet 101. The second air inlet 103 is disposed on the side wall of the second cavity 120. The second air inlet 103 connects to the indoor space and is used to supply air into the second cavity 120. The second air outlet 104 is disposed on the side wall of the second cavity 120. The second air outlet 104 is used to output the air that has entered the second cavity 120 from the second air inlet 103. The second air outlet 104 can be connected to the outdoor space through the second fan 4.

[0082] like Figure 2 As shown, the housing 1 includes a chassis 13, a first housing 11, and a second housing 12. The chassis 13 is generally plate-shaped, and can be flat. The chassis 13 can also be constructed as a generally rectangular plate. One surface of the chassis 13 faces upwards. Figure 5 , 14 As shown, a first region 131, a second region 133, and a connecting region 132 are provided on the upward-facing surface of the chassis 13. Both the first region 131 and the second region 133 are approximately rectangular. The connecting region 132 is located between the first region 131 and the second region 133, connecting the first region 131 and the second region 133. The connecting region 132 can be constructed as a straight strip, with the first region 131 and the second region 133 on opposite sides of the width of the connecting region 132. A first air outlet 102 is located on the first region 131, vertically penetrating the chassis 13.

[0083] The first housing 11 is disposed above the chassis 13. The first housing 11 covers the first region 131 of the chassis 13. The first housing 11 and the first region 131 of the chassis 13 enclose a first cavity 110. The first air inlet 101 is disposed on the side wall of the first housing 11.

[0084] The second shell 12 is arranged above the base plate 13. The second shell 12 covers the second area 133 of the base plate 13. The second shell 12 and the second area 133 of the base plate 13 enclose the second cavity 120. The second air inlet 103 and the second air outlet 104 are arranged on the side wall of the first shell 11.

[0085] The first fan 2 is connected to the shell 1. The first fan 2 is arranged in the first cavity 110. The first fan 2 is configured to drive the air in the first cavity 110 to flow from the first air inlet 101 of the first cavity 110 to the first air outlet 102 of the first cavity 110, so as to realize the circulation of air between the indoor space and the first cavity 110. The first fan 2 is provided with a first air inlet 211 and a first air outlet 213. The first fan 2 can suck air from the first air inlet 211 and output air from the first air outlet 213 when it is running. The bottom of the first fan 2 is connected to the bottom wall of the first cavity 110. The first air outlet 213 of the first fan 2 is connected to the first air outlet 102 of the first cavity 110, and the first air inlet 211 of the first fan 2 is connected to the internal space of the first cavity 110. The first fan 2 can suck the air in the first cavity 110 and deliver the air in the first cavity 110 to the outside of the shell 1 through the first air outlet 213 and the first air outlet 102 in sequence when it is running. After the first fan 2 sucks the air in the first cavity 110, the air pressure in the first cavity 110 is negative, and the air outside the shell 1 enters the first cavity 110 from the first air inlet 101. That is, the first fan 2 can drive the air to flow through the first cavity 110.

[0086] The first heat exchanger 3 is arranged in the first cavity 110. The first heat exchanger 3 can be arranged on the side of the first fan 2 close to the first air inlet 101. The air in the first cavity 110 flows through the first heat exchanger 3 when flowing from the first air inlet 101 to the first air outlet 102, and the first heat exchanger 3 can exchange heat with the air.

[0087] The second fan 4 can be arranged at the second air outlet 104. The second fan 4 is configured to drive the air in the second cavity 120 to flow from the second air inlet 103 of the second cavity 120 to the second air outlet 104 of the second cavity 120, so as to achieve the air in the indoor space being sucked into the second cavity 120 and then being delivered from the second cavity 120 to the outdoor space. The second fan 4 is provided with a second air inlet 411 and a second air outlet 413. The second air outlet 104 of the second cavity 120 is connected to the second air inlet 411 of the second fan 4. The second fan 4 can suck the air from the second air inlet 411 and output the air from the second air outlet 413 when the second fan 4 is running. The second air inlet 411 of the second fan 4 is connected to the second air outlet 104 of the second cavity 120, and the second air outlet 413 of the second fan 4 is used to be connected to the outdoor space. The second fan 4 can suck the air in the second cavity 120 and then deliver the air in the second cavity 120 to the outside of the shell 1 through the second air outlet 413 in sequence when the second fan 4 is running. After the second fan 4 sucks the air in the second cavity 120, the air pressure in the second cavity 120 is negative, and the air outside the shell 1 enters the second cavity 120 from the second air inlet 103. The second air outlet 413 of the second fan 4 faces one side of the shell 1, and the air output from the second air outlet 104 of the second cavity and entering the second fan 4 is delivered to the side of the shell 1 through the second air outlet 413. The second fan 4 can drive the air to flow through the second cavity 120.

[0088] The second heat exchanger 5 is arranged in the second cavity 120. The second heat exchanger 5 can be arranged between the second air inlet 103 and the second air outlet 104. The air in the second cavity 120 flows through the second heat exchanger 5 when flowing from the second air inlet 103 to the second air outlet 104, and the second heat exchanger 5 can exchange heat with the air.

[0089] The compressor 6 can be disposed within the housing 1. The compressor 6 can be disposed within the first cavity 110 or the second cavity 120. In this embodiment, the compressor 6 is disposed within the second cavity 120. The compressor 6 is connected to the first heat exchanger 3 and the second heat exchanger 5 via a refrigerant pipe 9. Refrigerant can be pre-filled into the refrigerant pipe 9, the first heat exchanger 3, and the second heat exchanger 5. The compressor 6 drives the refrigerant to circulate between the first heat exchanger 3 and the second heat exchanger 5, allowing heat to be transferred between them using the refrigerant as a carrier. In the cooling mode of the kitchen air conditioner 100, the first heat exchanger 3 acts as an evaporator, and the second heat exchanger 5 acts as a condenser. When the refrigerant flows through the first heat exchanger 3, it evaporates and absorbs heat from the air flowing through the first cavity. When the refrigerant flows through the second heat exchanger 5, it releases heat to the air flowing through the second cavity and condenses. In this way, the temperature of the air flowing through the first cavity decreases, and the air delivered to the room from the first air outlet 102 of the first cavity is cold air. Correspondingly, the temperature of the air flowing through the second cavity increases, and the air delivered to the outside from the second cavity is hot air.

[0090] A first housing 11 and a second housing 12 are spaced apart, and a clearance groove 14 is provided between the first housing 11 and the second housing 12, located above the connecting area 132. The clearance groove 14 can be a straight groove. The clearance groove 14 extends from one side of the housing 1 to the other side of the housing 1, penetrating the housing 1 in the horizontal direction. The depth of the clearance groove 14 can be 80% to 95% of the vertical dimension of the housing 1. A first cavity 110 and a second cavity 120 are located on opposite sides of the clearance groove 14, and the first cavity 110 and the second cavity 120 are separated by the clearance groove 14.

[0091] like Figure 24 As shown, the ceiling 1000 includes a keel 1100 as a supporting structure and spliced ​​decorative panels 1200 installed on the keel 1100. There are multiple spliced ​​decorative panels 1200 connected to the keel 1100. The multiple spliced ​​decorative panels 1200 are distributed in a matrix, so the ceiling 1000 appears as a horizontally arranged flat plate.

[0092] The keel 1100 comprises a plurality of first keels 1101, which are arranged in parallel and on the same horizontal plane, and are spaced apart from each other. The distance between any two adjacent first keels 1101 is the same. In some other embodiments, the keel further comprises a plurality of second keels 1102, which extend in a direction perpendicular to the first keels 1101. Any two adjacent second keels 1102 are spaced apart from each other. The distance between any two adjacent second keels 1102 is the same. The plurality of first keels 1101 and the plurality of second keels 1102 are configured as a mesh structure, and each of the spliced decorative plates covers a mesh hole in the mesh structure. The shape of the spliced decorative plate 1200 is not limited, and can be a square or a hexahedron, etc. The fixing manner of the keel 1100 on the wall 2000 is not limited, and in some embodiments, the end of the keel 1100 is fixed on the wall. The roof of the kitchen is provided with a hoisting structure, and the keel 1100 is fixed on the hoisting structure, so that the whole ceiling 1000 is hoisted.

[0093] According to the prior art, when the integrated kitchen air conditioner is installed in front, the machine body is first installed, and then the ceiling is installed. Or the ceiling is first installed with part of the keel, and then the machine body is hoisted, and the remaining keel and spliced decorative plate are installed therebetween. When the integrated kitchen air conditioner is installed at the back, due to the large size of the integrated kitchen air conditioner, part of the spliced decorative plate and the keel also need to be removed for installation. When the kitchen air conditioner needs to be cleaned or maintained, at least part of the spliced decorative plate needs to be removed. If the machine needs to be disassembled for repair, the keel of the ceiling also needs to be removed. This results in that the cleaning and maintenance of the kitchen air conditioner are very time-consuming and laborious, and the operation is complicated.

[0094] The kitchen air conditioner 100 can solve the above problems, and the kitchen air conditioner 100 is provided with a let-in through slot 14 at the top of the shell 1, the let-in through slot 14 can pass the first keel 1101, when the kitchen air conditioner 100 is installed, the opening of the let-in through slot 14 is aligned with the first keel 1101 below the ceiling, then the height of the kitchen air conditioner 100 is lifted to make the first keel 1101 enter the let-in through slot 14, until the first keel 1101 is located at the bottom of the let-in through slot 14, finally the kitchen air conditioner 100 is fixed, for example, the kitchen air conditioner 100 is hoisted and fixed, and the installation is completed, and the installed keel does not need to be disassembled during the installation process of the kitchen air conditioner 100. After the installation of the kitchen air conditioner 100 is completed, except for the end of the bottom end of the shell 1, the other parts of the shell 1 can be hidden in the space above the ceiling, and the kitchen air conditioner 100 is more beautiful. Correspondingly, when the kitchen air conditioner 100 needs to be overhauled, the kitchen air conditioner 100 only needs to be disassembled by removing the fixing of the kitchen air conditioner 100 and vertically lowering the height of the kitchen air conditioner 100, and the installed keel does not need to be disassembled during the disassembly process of the kitchen air conditioner 100. Compared with the prior art, the kitchen air conditioner of the embodiment of the utility model reduces the maintenance steps and time, improves the maintenance efficiency, improves the installation convenience of the kitchen air conditioner 100, and reduces the installation time.

[0095] As shown in Figure 12 、 13 , the second fan 4 includes a second air duct piece 41, a second air wheel 42 and a second motor 43. The second air duct piece 41 is provided with a second air inlet 411, a second air outlet 413 and a second air duct 412. The second air wheel 42 can be a centrifugal air wheel. The second air duct 412 extends from the second air inlet 411 to the second air outlet 413. The second air wheel 42 is arranged in the second air duct 412. The body of the second motor 43 is connected to the second air duct piece 41. The main shaft of the second motor 43 is connected to the second air wheel 42. The second motor 43 can drive the second air wheel 42 to rotate, and the second air wheel 42 can drive the air in the second air duct 412 to flow from the second air inlet 411 to the second air outlet 413 when the second air wheel 42 rotates. The second air duct piece 41 covers the second air outlet 104 of the second shell 12. The second air inlet 411 on the second air duct piece 41 is arranged to be communicated with the second air outlet 104. The second air outlet 413 is configured to be communicated with the outdoor space. One end of the outdoor exhaust duct can be connected to the second air outlet 413, and the other end of the outdoor exhaust duct extends to the outdoor, and the second air outlet 413 can be communicated with the outdoor space through the outdoor exhaust duct.

[0096] The second air duct piece 41 is arranged between the second cavity 120 and the let-in through slot 14. The second air duct piece 41 serves as a side wall of the let-in through slot 14 and a wall surface of the second cavity 120. The second air duct piece 41 is a common wall surface of the let-in through slot 14 and the second cavity 120.

[0097] In this way, the second air duct member 41 of the second fan 4 is arranged outside the second cavity 120 and serves as a wall of the second cavity 120, and the second air duct member 41 also serves as a side wall of the accommodation slot 14, so that the size of the kitchen air conditioner 100 in the width direction of the accommodation slot 14 can be reduced, and the volume of the kitchen air conditioner 100 is smaller.

[0098] In addition, the first fan 2, the second fan 4, the first heat exchanger 3, the second heat exchanger 5, and the compressor 6 are all mounted on the shell 1, and the kitchen air conditioner 100 is configured as an all-in-one machine, and the structure of the kitchen air conditioner 100 is simple, and efficient production and rapid installation can be achieved. At the same time, after the shell 1 of the kitchen air conditioner 100 is embeddedly installed on the ceiling, the first air inlet 101, the second air inlet 103, and the second air outlet 104 are all located above the ceiling, and the first air inlet 101, the second air inlet 103, and the second air outlet 104 of the shell 1 of the kitchen air conditioner 100 can be hidden above the ceiling, which is more beautiful, and the second fan 4 can deliver the air output from the second cavity 120 to the side of the shell 1, so that the outdoor exhaust duct can be connected to the kitchen air conditioner 100 from the side of the shell 1, without additional installation space required for the kitchen air conditioner 100 in the vertical direction. The first air outlet 102 of the kitchen air conditioner 100 delivers air to the lower side of the shell 1, which can quickly adjust the temperature of the space below the ceiling and improve the user experience.

[0099] In an illustrative embodiment, as shown in Figure 3 、 8 The second shell 12 includes a third plate member 122, a second top plate 121, and a fourth plate member 123. The third plate member 122 includes a third side plate 1221 and a fourth side plate 1222. The third side plate 1221 is configured as a plate-shaped structure perpendicular to the bottom disc 13.

[0101] The second top plate 121 is arranged above the second region 133 of the chassis 13. The shape of the second top plate 121 can be the same as that of the second region 133. The second top plate 121 is parallel to the chassis 13. The second top plate 121 connects the third side plate 1221, the fourth side plate 1222 and the fourth plate member 123 at the end thereof, which faces away from the chassis 13.

[0102] As shown in Figure 5 , 7 The second air outlet 104 of the second housing 12 is enclosed by the fourth side plate 1222, the fourth plate member 123, the second top plate 121 and the end of the second region 133 of the chassis 13, which faces away from the third side plate 1221. The second air duct member 41 abuts against the fourth side plate 1222, the fourth plate member 123 and the end of the second top plate 121, which faces away from the third side plate 1221, and also abuts against the chassis 13, so that the second air duct member 41 covers the second air outlet 104 of the second housing 12.

[0103] In one illustrative embodiment, as shown in Figure 12 , 13 The second air duct member 41 includes a first plate body 414, a second plate body 415 and a second volute 416. The first plate body 414 and the second plate body 415 are configured as flat plates. The first plate body 414 extends from the boundary between the second region 133 and the connecting region 132 to the second top plate 121. The first plate body 414 and the second plate body 415 are parallel to each other and spaced apart. The second plate body 415 is arranged on the side of the first plate body 414, which is close to the second heat exchanger 5. The second volute 416 is arranged between the first plate body 414 and the second plate body 415, and the first plate body 414 and the second plate body 415 cover opposite ends of the second volute 416, respectively. The second air duct 412 is arranged in the second volute 416. The second air outlet 413 is arranged on the peripheral wall of the second volute 416. The second air inlet 411 is arranged on the second plate body 415. The second fan wheel 42 is arranged in the second volute 416, and the second motor 43 is arranged in the second fan wheel 42. The body of the second motor 43 is connected to the first plate body 414, and the main shaft of the second motor 43 is connected to the second fan wheel 42. The lower end of the second volute 416 extends into the recess 1331 of the chassis 13. The structure of the second fan 4 is more compact.

[0104] In an illustrative embodiment, the second heat exchanger 5 is arranged in the second cavity 120 and sandwiched between the second air duct member 41 and the third side plate 1221, and opposite sides of the second heat exchanger 5 are connected to the second air inlet 411 of the second air duct member 41 and the second air inlet 103 of the third side plate 1221, respectively. The second heat exchanger 5 can be a straight heat exchanger with multiple rows, and the second air inlet 411 faces the second heat exchanger 5.

[0105] In an illustrative embodiment, as shown in FIG. 3, Figure 1 , 2 The first shell 11 includes a partition plate 114, a first plate member 112, a second plate member 113, and a first top plate 111. The partition plate 114 can be configured as a rectangular plate. The partition plate 114 is arranged vertically. The partition plate 114 extends upward from the boundary between the first region 131 and the connecting region 132 of the bottom plate 13. The partition plate 114 and the bottom plate 13 can be connected by screws, welding, or riveting. In the present embodiment, the bottom end of the partition plate 114 near the bottom plate 13 can be provided with a flange abutting against the bottom plate 13, and the flange and the bottom plate 13 are connected by screws.

[0106] As shown in FIG. 3, Figure 10 The first plate member 112 includes a first side plate 1121 and a second side plate 1122. The first side plate 1121 extends upward from the edge of the first region 131 of the bottom plate 13 away from the connecting region 132. The first side plate 1121 is perpendicular to the bottom plate 13. The first side plate 1121 can be parallel to the partition plate 114. The first side plate 1121 is provided with a first air inlet 101. The first air inlet 101 provided on the first side plate 1121 can be a rectangular opening. The area of the first air inlet 101 provided on the first side plate 1121 can be slightly smaller than the area of the first side plate 1121. The first air inlet 101 can be large enough. The second side plate 1122 is perpendicular to the bottom plate 13. The second side plate 1122 extends from one end of the first side plate 1121 along the edge of the first region 131 on one side to one end of the partition plate 114. The extension direction of the second side plate 1122 is substantially perpendicular to the plate surface of the partition plate 114. The second side plate 1122 can be provided with a side air inlet as part of the first air inlet 101. The first side plate 1121 and the second side plate 1122 are both connected to the bottom plate 13 by screws. In the present embodiment, the bottom end of the partition plate 114 near the second side plate 1122 can be provided with a flange abutting against the second side plate 1122, and the flange and the second side plate 1122 are connected by screws.

[0107] As shown in FIG. 3, Figure 14As shown, the second plate member 113 is configured as a flat plate, which can be a rectangular flat plate. The second plate member 113 is arranged at the edge of the first area 131 facing away from the second side plate 1122. The second plate member 113 is arranged vertically. The second plate member 113 extends from the end of the first side plate 1121 facing away from the second side plate 1122 along the edge of the first area 131 to the end of the partition plate 114 facing away from the second side plate 1122. The second side plate 1122 is connected to the first side plate 1121 and the partition plate 114. The first side plate 1121 and the partition plate 114 are connected to the second side plate 1122 by screwing, welding or riveting. In the present embodiment, the second plate member 113 is configured as an integrally formed structure with the bottom plate 13, which can reduce the assembly steps and at the same time enhance the connection strength between the second plate member 113 and the bottom plate 13, so that the second plate member 113 can be more stably connected to the bottom plate 13.

[0108] As shown in Figure 1 , the first top plate 111 is arranged above the first area 131 of the bottom plate 13 and has a space with the bottom plate 13. The shape of the first top plate 111 is the same as that of the first area 131. The first top plate 111 is parallel to the bottom plate 13. The first top plate 111 is connected to the end of the partition plate 114, the first side plate 1121, the second side plate 1122 and the second plate member 113 facing away from the bottom plate 13. The partition plate 114, the first side plate 1121, the second side plate 1122, the second plate member 113 and the first top plate 111 can be connected by welding, screwing or riveting. In the present embodiment, the end of the partition plate 114 close to the first top plate 111 can be provided with a flange, which is screwed to the first top plate 111.

[0109] In this way, the bottom plate 13, the partition plate 114, the first plate member 112, the second plate member 113 and the first top plate 111 enclose the first cavity 110, and the first shell 11 is assembled by the partition plate 114, the first plate member 112, the second plate member 113 and the first top plate 111, which has a simple structure, is easy to process and has low cost.

[0110] As shown in Figure 5 , the give-way slot 14 is enclosed by the second air duct member 41 of the second fan 4, the connecting area 132 of the bottom plate 13 and the partition plate 114 of the first shell 11.

[0111] In an illustrative embodiment, as shown in Figure 14 , the kitchen air conditioner 100 further comprises a protective cover 141 and a throttling element. The protective cover 141 can be configured as a straight strip, and the protective cover 141 covers the slot bottom of the give-way slot 14. The protective cover 141 is connected to the shell 1, and the connection between the protective cover 141 and the shell 1 can be a snap connection or a screw connection. The protective cover 141 and the slot bottom of the give-way slot 14 form a pipe laying channel. The protective cover 141 can be an integrally formed structure, and the cover plate 141 can also be assembled by multiple flat plates.

[0112] The throttling element and the compressor 6 are arranged in the second cavity 120. The compressor 6, the second heat exchanger 5, the throttling element and the first heat exchanger 3 are connected in sequence by the refrigerant pipes to form a refrigeration circuit. The outlet of the compressor 6 is connected to the inlet of the second heat exchanger 5 by a refrigerant pipe 9. The outlet of the second heat exchanger 5 is connected to the throttling element by a refrigerant pipe 9. The throttling element is further connected to the inlet of the first heat exchanger 3 by a refrigerant pipe 9. The outlet of the first heat exchanger 3 is connected to the inlet of the compressor 6 by a refrigerant pipe 9.

[0113] At least part of the refrigerant pipes 9 are arranged in the pipe arranging passage, so that the refrigerant pipes 9 can pass from below the accommodation slot 4. The part of the refrigerant pipes 9 includes the refrigerant pipes 9 connecting the first heat exchanger 3 and the compressor 6, and the refrigerant pipes 9 connecting the first heat exchanger 3 and the throttling element. The pipe arranging distance is short, and the pipe arranging cost can be reduced. Meanwhile, the pipe arranging passage also protects the refrigerant pipes 9 from interference or collision with the keel, so as to avoid damage to the refrigerant pipes 9.

[0114] In an exemplary embodiment, as shown in Figure 8 The first heat exchanger 3 is configured as a U-shaped heat exchanger. The first heat exchanger 3 extends from one end of the partition plate 114 to the other end of the partition plate 114 along the second plate member 113, the first side plate 1121 and the second side plate 1122 in sequence. The two ends of the first heat exchanger 3 are close to the two ends of the partition plate 114 respectively. The first heat exchanger 3 and the partition plate 114 enclose an internal cavity. The bottom end of the first heat exchanger 3 is connected to the bottom plate 13.

[0115] As shown in Figure 8 The first fan 2 is arranged in the internal cavity enclosed by the first heat exchanger 3 and the partition plate 114. The first air inlet 211 of the first fan 2 is connected to the internal cavity. The first air outlet 213 of the first fan 2 is connected to the first air outlet 102 on the bottom plate 13.

[0116] The first heat exchanger 3 is configured as a U-shaped heat exchanger, and has a large contact area with air, so that the heat exchange efficiency is high. Since the first fan 2 is arranged in the internal cavity enclosed by the first heat exchanger 3 and the partition plate 114, the layout is compact, and the first cavity 110 can be correspondingly reduced, so that the overall volume of the kitchen air conditioner 100 is small.

[0117] In an exemplary embodiment, as shown in Figure 9As shown, the first air blower 2 comprises a first air duct member 21, two first air wheels 22 and a first motor 23. The first air duct member 21 comprises two first volutes 214 and a connecting shell 215. The two first volutes 214 are arranged side by side and spaced apart from each other. The connecting shell 215 connects the two first volutes 214. Each first volute 214 is provided with a first air inlet 211, a first air outlet 213 and a first air duct 212 connecting the first air inlet 211 and the first air outlet 213. The first air outlets 213 of the two first volutes 214 penetrate through the connecting shell 215 and are communicated with the first air outlets 102 on the bottom plate 13. The first air inlets 211 of the two first volutes 214 are communicated with the first heat exchanger 3 and the internal cavity enclosed by the partition plate 114.

[0118] The two first air wheels 22 are arranged in the first air ducts 212 of the two first volutes 214 respectively. The first air wheel 22 can be a centrifugal air wheel. The two first air wheels 22 are coaxially arranged. The first motor 23 is arranged between the two first air wheels 22, and the two ends of the main shaft of the first motor 23 are connected to the two first air wheels 22 respectively. The first motor 23 can drive the two first air wheels 22 to rotate synchronously. When the first air wheel 22 rotates, it can drive the air in the first air duct 212 of the first volute 214 where the first air wheel 22 is located to flow from the first air inlet 211 to the first air outlet 213. The first motor 23 can be mounted on the connecting shell 215, and the first air duct member 21, the two first air wheels 22 and the first motor 23 form a module.

[0119] In this way, the two first air wheels 22 of the first air blower 2 rotate synchronously to perform air supply, and the air volume of air supply is larger. At the same time, the first motor 23 is arranged between the two first air wheels 22 and the two first volutes 214, so that the structure of the first air blower 2 is more compact, the installation space required by the first air blower 2 is smaller, and the shell 1 can be arranged smaller.

[0120] Each first volute 214 can be provided with a first air inlet 211 on each side, thereby increasing the air volume. The U-shaped heat exchanger can be arranged around the first air blower 2, and the two first air inlets 211 of the two first volutes 214 facing away from each other are respectively directed towards the two ends of the U-shaped heat exchanger.

[0121] In an exemplary embodiment, as shown in Figure 9 The bottom of the first air duct member 21 is provided with a male buckle 216. The male buckle 216 can be provided with two, and the two male buckles 216 are arranged on the sides of the two first volutes 214 close to the bottom plate 13. As shown in Figure 14 The first area 131 of the bottom plate 13 is provided with a female buckle 139. The number of female buckles 139 is the same as that of male buckles 216. The female buckles 139 and the male buckles 216 are arranged one by one. Each male buckle 216 is inserted into the female buckle 139 corresponding thereto to realize the snap connection between the first air duct member 21 and the bottom plate 13.

[0122] The first air duct 21 is snap-connected with the bottom plate 13, so that the assembly between the first air blower 2 and the bottom plate 13 is more convenient and the assembly speed is improved.

[0123] In an illustrative embodiment, as shown in Figure 14 , the second region 133 of the bottom plate 13 is provided with a clearance 1331. The clearance 1331 vertically penetrates the bottom plate 13. The clearance 1331 can be configured as a rectangular opening.

[0124] The second air duct 41 of the second air blower 4 partially extends into the clearance 1331. The lower surface of the part of the second air duct 41 extending into the clearance 1331 is flush with the lower surface of the bottom plate 13, or the part of the second air duct 41 extending into the clearance 1331 can pass through the clearance 1331 so that the lower surface thereof is slightly protruded from the lower surface of the bottom plate 13.

[0125] In this way, the second air duct 41 of the second air blower 4 can partially extend into the clearance 1331, which is beneficial to increase the size of the second air blower 4 to increase the air volume of the second air blower 4 or reduce the thickness of the kitchen air conditioner 100 in the vertical direction.

[0126] In an illustrative embodiment, as shown in Figure 14 , 15 , the upper surface of the bottom plate 13 of the shell 1 is further provided with a water collecting groove 134, a water hitting groove 136 and a water guiding groove 135. The water collecting groove 134 is arranged at the first region 131 of the bottom plate 13 and is located below the first heat exchanger 3. The shape of the water collecting groove 134 can be the same as the shape of the projection of the first heat exchanger 3 on the bottom plate 13, for example, both are configured as a U shape. The water hitting groove 136 is arranged at the second region 133 of the bottom plate 13 and is located below the second heat exchanger 5. The height of the groove bottom of the water collecting groove 134 can be greater than or equal to the height of the groove bottom of the water hitting groove 136. The water guiding groove 135 extends from the water collecting groove 134 to the water hitting groove 136. The water guiding groove 135 connects the water collecting groove 134 and the water hitting groove 136. The water guiding groove 135 can have a decreasing trend in the height of the groove bottom in the direction from the water collecting groove 134 to the water hitting groove 136.

[0127] As shown in Figure 14 , 16 , the kitchen air conditioner 100 further comprises a water hitting assembly 7. The water hitting assembly 7 is arranged on the bottom plate 13. The water hitting assembly 7 can be arranged at the second region 133. The water hitting assembly 7 comprises a water hitting wheel 71 and a water hitting motor 72. The water hitting wheel 71 is configured as a substantially disc shape. The water hitting wheel 71 is arranged above the bottom plate 13. The axis of the water hitting wheel 71 is horizontally arranged, and the water hitting wheel 71 at least partially extends into the water hitting groove 136. The water hitting motor 72 is drivingly connected to the water hitting wheel 71. The water hitting motor 72 can drive the water hitting wheel 71 to rotate.

[0128] When the kitchen air conditioner 100 is running in the cooling mode, the temperature of the first heat exchanger 3 is lower than the temperature of the air flowing through the first cavity 110, and the pre-cooling of the water vapor in the air will condense to the surface of the first heat exchanger 3 to form condensate water droplets. The condensate water droplets on the surface of the first heat exchanger 3 will drip into the water collecting groove 134 under the action of force and be collected. The condensate water in the water collecting groove 134 will flow into the water hitting groove 136 along the water guide groove 135. Since the water hitting wheel 71 extends into the water hitting groove 136, it can be in contact with the condensate water in the water hitting groove 136. When the water hitting motor 72 drives the water hitting wheel 71 to rotate, it can throw the condensate water in the water hitting groove 136 onto the second heat exchanger 5. When the kitchen air conditioner 100 is running in the cooling mode, the surface temperature of the second heat exchanger 5 is relatively high, which can release heat to the condensate water to evaporate the condensate water. When the condensate water is evaporated, it absorbs the heat released by the second heat exchanger 5, thereby improving the heat exchange efficiency of the second heat exchanger 5 and further improving the energy efficiency of the kitchen air conditioner 100. At the same time, after the condensate water is evaporated, the water amount of the condensate water in the water hitting groove 136 can be reduced, avoiding the overflow of the condensate water in the bottom plate 13. Therefore, it is not necessary to set a drain pipe to lead the condensate water in the bottom plate 13 out of the kitchen air conditioner 100.

[0129] In an illustrative embodiment, as shown in FIG. 1, the kitchen air conditioner 100 further comprises a water level switch 8. The water level switch 8 can be arranged in the water hitting groove 136 or arranged at the end of the water guide groove 135 close to the water hitting groove 136. The water level switch 8 can detect whether the water level in the water hitting groove 136 or the water guide groove 135 reaches a preset threshold. The water level switch 8 is configured to shut down the compressor 6 when it detects that the water level in the water hitting groove 136 or the water guide groove 135 reaches the preset threshold. Figure 14 The preset threshold can be set to be slightly smaller than the water level height at which the water level switch 8 detects that the condensate water overflows from any one of the water hitting groove 136, the water collecting groove 134 and the water guide groove 135. When the water level in the water hitting groove 136 or the water guide groove 135 reaches the preset threshold, it indicates that there is a risk of the condensate water overflowing from the water hitting groove 136, the water collecting groove 134 or the water guide groove 135. At this time, the compressor 6 is shut down, so that the rate of the condensate water generated by the first heat exchanger 3 decreases, and at the same time, the water hitting wheel 71 is kept rotating to continuously consume the condensate water that has been generated, which can prevent the condensate water from overflowing in the case of very high air humidity.

[0130] The water guide groove 135 crosses through the pipe arranging passage, so that the keel located in the accommodation passage will not cut off the water guide groove 135 to cause the condensate water to overflow from the kitchen air conditioner.

[0131] In an illustrative embodiment, as shown in FIG. 1, the kitchen air conditioner 100 further comprises a water level switch 8. The water level switch 8 can be arranged in the water hitting groove 136 or arranged at the end of the water guide groove 135 close to the water hitting groove 136. The water level switch 8 can detect whether the water level in the water hitting groove 136 or the water guide groove 135 reaches a preset threshold. The water level switch 8 is configured to shut down the compressor 6 when it detects that the water level in the water hitting groove 136 or the water guide groove 135 reaches the preset threshold.

[0132] Figure 14 ​As shown, the bottom plate 13 is further provided with a collecting groove 137. The collecting groove 137 is located below the second heat exchanger 5. The water striking groove 136 and the collecting groove 137 are arranged in sequence in the flow direction of the air in the second cavity, for example, in the direction from the second air inlet 103 to the second air outlet 104. The extending direction of the water striking groove 136 and the extending direction of the collecting groove 137 can both be perpendicular to the flow direction of the air in the second cavity. The water striking groove 136 and the collecting groove 137 are separated by a baffle. The baffle is provided with a through opening 138. The through opening 138 can be provided as a through hole penetrating the baffle or as a notch penetrating the baffle. The through opening 138 can be located higher than the groove bottom of the water striking groove 136. The through opening 138 can be provided in the middle region of the baffle in the vertical direction. The two ends of the through opening 138 are respectively communicated with the collecting groove 137 and the water striking groove 136.

[0133] In this way, after the water striking wheel 71 throws out the condensed water, a part of the condensed water drops will be driven by the air flow in the second cavity 120 to move a distance downstream of the air flow. At the same time, the condensed water that is not completely evaporated by the second heat exchanger 5 will also drop downward. These condensed water drops will also be driven by the air flow in the second cavity 120 to move a distance downstream of the air flow. A part of the condensed water drops deviated by the air flow will not fall back into the water striking groove 136, but will fall into the collecting groove 137 and be collected. Then the collected condensed water will reflow from the collecting groove 137 to the water striking groove 136, preventing the condensed water from splashing to other areas of the bottom plate 13 due to the action of the wind force, thereby preventing the condensed water from overflowing.

[0134] In an illustrative embodiment, the machine body of the water striking motor 72 is arranged below the side of the second volute 416 and is fixed to the bottom plate 13. In this embodiment, the second plate body 415 is recessed towards the first plate body 414 to form a recessed groove 4151 below the side of the second volute 416. The machine body of the water striking motor is arranged in the recessed groove 4151.

[0135] Arranging the machine body of the water striking motor 72 below the side of the second volute 416 can make full use of the gap space between the volute and the bottom plate 13, so that the structure of the kitchen air conditioner 100 is more compact.

[0136] In an illustrative embodiment, the second heat exchanger 5 includes a plurality of heat exchange tube rows, and the number of heat exchange tube rows is at least four. The heat exchange tube rows are arranged in sequence in the flow direction of the air in the second cavity 120. The heat exchange flow channels of the plurality of heat exchange tube rows are connected in sequence according to the arrangement direction.

[0137] In this way, the second heat exchanger 5 is provided with four or more heat exchange tube rows for heat exchange, so that the heat exchange efficiency is higher and the refrigerating capacity in the refrigerating mode is larger.

[0138] In an illustrative embodiment, as shown inFigure 8 As shown, the compressor 6 is arranged in the second cavity 120 of the housing 1. The compressor 6 is located at the end of the second fan 4 which is away from the second air outlet 413. The compressor 6 can be arranged at the end of the second fan 4 which is away from the fourth plate 123. The second heat exchanger 5 is arranged at the side of the second fan 4 which is away from the first cavity 110. The compressor 6 can be arranged at the end of the second heat exchanger 5 which is away from the fourth plate 123.

[0139] In this way, the compressor 6 is arranged at the end of the second fan 4, so that the compressor 6 and the pipeline connected therewith can make full use of the space in the second cavity 120, so that the structure of the kitchen air conditioner 100 is more compact and smaller in size.

[0140] In an exemplary embodiment, as shown, Figures 17-20 The kitchen air conditioner 100 further comprises an electric control box 2a. The electric control box 2a is connected to the first housing 11. The electric control box 2a can be connected to the second plate 113.

[0141] The electric control box 2a comprises a box body 21a, a control board 27a, a heat dissipation bottom plate 22a, a heat dissipation cover plate 23a and a cooling pipe 24a. The box body 21a is configured as a box-shaped structure. The box body 21a can be made of an insulating material, such as plastic. The box body 21a is provided with a cavity. The control board 27a is a logic control unit of the kitchen air conditioner 100.

[0142] The control board 27a is arranged in the cavity of the box body 21a. The control board 27a is a logic control unit of the kitchen air conditioner 100. A plurality of electrical elements are arranged on the control board 27a. Some of the electrical elements can be chips. The electrical elements generate heat during operation.

[0143] The heat dissipation bottom plate 22a is made of a metal material, such as aluminum or an alloy of aluminum. The heat dissipation bottom plate 22a has good heat conduction performance. The heat dissipation bottom plate 22a can be configured as a rectangular plate. One plate surface of the heat dissipation bottom plate 22a abuts against the control board 27a.

[0144] The heat dissipation cover plate 23a is made of a metal material, such as aluminum or an alloy of aluminum. The heat dissipation cover plate 23a has good heat conduction performance. The heat dissipation cover plate 23a covers the plate surface of the heat dissipation bottom plate 22a which is away from the control board 27a. The heat dissipation cover plate 23a and the heat dissipation bottom plate 22a enclose the cooling channel 20a. In the present embodiment, as shown, Figure 20 The plate surface of the heat dissipation bottom plate 22a which faces the heat dissipation cover plate 23a is inwardly recessed to form a first recess 221a. The plate surface of the heat dissipation cover plate 23a which faces the heat dissipation bottom plate 22a is inwardly recessed to form a second recess 231a. The first recess 221a and the second recess 231a have the same shape, and the first recess 221a and the second recess 231a are aligned with each other. The inner walls of the first recess 221a and the second recess 231a enclose the cooling channel 20a.

[0145] The cooling pipe 24a can be made of metal material. The cooling pipe 24a can be a copper pipe or an aluminum pipe. The shape of the cooling pipe 24a is the same as that of the cooling channel 20a. The cooling pipe 24a is arranged in the cooling channel 20a and extends along the cooling channel 20a. The outer diameter of the cooling pipe 24a is equal to the diameter of the cooling channel 20a, and the outer wall of the cooling pipe 24a abuts against the inner wall of the cooling channel 20a. The two ends of the cooling pipe 24a extend out of the space between the heat dissipation cover plate 23a and the heat dissipation bottom plate 22a. The ends of the cooling pipe 24a can be bent relative to the cooling channel 20a, so that the electric control box 2a can be vertically arranged on the air conditioner, and the cooling pipe 24a is connected to the refrigerant circulation system.

[0146] The throttling element can be an electronic expansion valve or a capillary tube. The throttling element can be arranged in the second cavity 120 and close to the compressor 6.

[0147] In some illustrative embodiments, the compressor 6, the second heat exchanger 5, the cooling pipe 24a, the throttling element, and the first heat exchanger 3 are sequentially connected to form a refrigeration circuit. The outlet of the compressor 6 is connected to the inlet of the second heat exchanger 5 through the refrigerant pipe 9. The outlet of the second heat exchanger 5 is connected to one end of the cooling pipe 24a through the refrigerant pipe 9. The other end of the cooling pipe 24a is connected to the throttling element through the refrigerant pipe 9. The throttling element is further connected to the inlet of the first heat exchanger 3 through the refrigerant pipe 9. The outlet of the first heat exchanger 3 is connected to the inlet of the compressor 6 through the refrigerant pipe 9.

[0148] In this way, when the kitchen air conditioner 100 is working, the control panel 27a generates heat and conducts the heat to the heat dissipation bottom plate 22a. Part of the heat on the heat dissipation bottom plate 22a is directly conducted to the cooling pipe 24a, and the other part of the heat on the heat dissipation bottom plate 22a is first transferred to the heat dissipation cover plate 23a, and then the heat dissipation cover plate 23a further transfers the heat to the cooling pipe 24a. In the refrigeration mode of the kitchen air conditioner 100, the compressor 6 compresses the refrigerant and outputs the high-temperature and high-pressure refrigerant to the second heat exchanger 5. The refrigerant transfers heat to the air flowing through the second cavity when flowing through the second heat exchanger 5, and the refrigerant is cooled to low-temperature refrigerant. The low-temperature refrigerant is transported from the second heat exchanger 5 to the cooling pipe 24a, and the refrigerant absorbs the heat on the heat dissipation bottom plate 22a and the heat dissipation cover plate 23a when flowing through the cooling pipe 24a, thereby taking out the heat generated by the control panel 27a from the electric control box 2a. After the refrigerant enters the throttling element, the throttling element throttles and depressurizes the refrigerant, and then the refrigerant is transported to the first heat exchanger 3 to absorb the heat of the air flowing through the first cavity to evaporate. The refrigerant returns to the compressor 6 to complete a cycle.

[0149] In another exemplary embodiment, the compressor 6, the second heat exchanger 5, the throttling element and the first heat exchanger 3 are connected in sequence to form a refrigeration circuit, the cooling pipe 24a is connected to the refrigerant from the second heat exchanger 5 and the refrigerant flows back to the second heat exchanger 5 after passing through the cooling pipe 24a. The outlet of the compressor 6 is connected to the inlet of the second heat exchanger 5 through the refrigerant pipe 9. The outlet of the second heat exchanger 5 is connected to the throttling element through the refrigerant pipe 9. The throttling element is connected to the inlet of the first heat exchanger 3 through the refrigerant pipe 9. The outlet of the first heat exchanger 3 is connected to the inlet of the compressor 6 through the refrigerant pipe 9. The cooling pipe 24a can be connected to the refrigerant from the main flow path or the branch flow path of the second heat exchanger 5, and the refrigerant flows back to the second heat exchanger 5 before the supercooling section of the second heat exchanger 5 after passing through the cooling pipe 24a, and then flows to the supercooling section.

[0150] In this way, the control panel 27a generates heat during the operation of the kitchen air conditioner 100, and the heat is conducted to the heat dissipation bottom plate 22a. Some of the heat on the heat dissipation bottom plate 22a is directly conducted to the cooling pipe 24a, and the other part of the heat on the heat dissipation bottom plate 22a is first transferred to the heat dissipation cover plate 23a, and then the heat dissipation cover plate 23a transfers the heat to the cooling pipe 24a. In the refrigeration mode of the kitchen air conditioner 100, the compressor 6 compresses the refrigerant and outputs the high-temperature and high-pressure refrigerant to the second heat exchanger 5. The refrigerant transfers heat to the air flowing through the second cavity when flowing through the second heat exchanger 5, and the refrigerant is cooled to low-temperature refrigerant. The refrigerant is transported from the second heat exchanger 5 to the cooling pipe 24a, and absorbs the heat on the heat dissipation bottom plate 22a and the heat dissipation cover plate 23a when flowing through the cooling pipe 24a, thereby taking away the heat generated by the control panel 27a from the electric control box 2a. The refrigerant reenters the second heat exchanger 5 for cooling, so that the refrigeration effect does not decrease. The refrigerant enters the throttling element after passing through the second heat exchanger 5, the throttling element throttles and depressurizes the refrigerant, and the refrigerant is transported to the first heat exchanger 3 and evaporates by absorbing the heat of the air flowing through the first cavity, and then returns to the compressor 6 to complete a cycle.

[0151] Thus, the refrigerant can take away the heat generated by the control panel 27a during the circulation process, and the heat dissipation is fast, which ensures that the temperature in the electric control box 2a does not become too high, and the electrical components on the control panel 27a can work stably at a suitable temperature. At the same time, the structure of the electric control box 2a is simple, and it is easy to assemble and disassemble.

[0152] In an exemplary embodiment, as shown in Figure 19 The cooling pipe 24a and the cooling channel 20a are both configured in a U shape.

[0153] The U-shaped cooling pipe 24a has a large contact area with the heat dissipation bottom plate 22a and the heat dissipation cover plate 23a, and the heat conduction between the cooling pipe 24a and the heat dissipation bottom plate 22a and the heat dissipation cover plate 23a is faster, and the cooling effect is better. At the same time, the U-shaped cooling pipe 24a has a simple structure and is easy to manufacture.

[0154] In an illustrative embodiment, the control board 27a comprises a circuit board 271a and a chip (not shown in the figure). The circuit board 271a is configured as a flat plate. The circuit board 271a can be a printed circuit board 271a. The chip is disposed on one plate surface of the circuit board 271a. The chip can be soldered on the circuit board 271a. The circuit board 271a is fixed on the box body 21a. The connection between the circuit board 271a and the box body 21a can be screw connection.

[0155] As shown in the figure, the electric control box 2a further comprises an insulating support 25a. The insulating support 25a is made of insulating material. The insulating support 25a can be configured as a rectangular plate structure. The insulating support 25a is provided with a first through hole 214a. The first through hole 214a vertically penetrates the insulating support 25a. One plate surface of the insulating support 25a abuts against the circuit board 271a. The insulating support 25a is connected to the circuit board 271a. The connection between the insulating support 25a and the circuit board 271a can be screw connection. The extension direction of the first through hole 214a is perpendicular to the plate surface of the circuit board 271a. Figure 20 The heat dissipation bottom plate 22a is disposed on the side of the insulating support 25a away from the circuit board 271a and is connected to the insulating support 25a. The heat dissipation bottom plate 22a can cover the plate surface of the insulating support 25a away from the circuit board 271a. One end of the first through hole 214a faces the circuit board 271a and the other end of the first through hole 214a faces the heat dissipation bottom plate 22a. The chip of the control board 27a penetrates the first through hole 214a of the insulating support 25a and the surface of the chip away from the circuit board 271a abuts against the heat dissipation bottom plate 22a.

[0156] In this way, the heat dissipation bottom plate 22a is disposed on the side of the insulating support 25a away from the circuit board 271a, and the insulating support 25a separates the heat dissipation bottom plate 22a and the circuit board 271a of the control board 27a from each other, preventing the heat dissipation bottom plate 22a from directly contacting the circuit board 271a and causing short circuit of the circuit on the circuit board 271a. Meanwhile, the chip is the main heat source on the control board 27a, and the chip can contact the heat dissipation bottom plate 22a through the first through hole 214a, and the heat dissipation bottom plate 22a can conduct the heat generated by the chip to the cooling pipe 24a, avoiding the temperature of the chip being too high.

[0157] In an illustrative embodiment, the side of the chip away from the circuit board 271a is provided with a positioning protrusion. The positioning protrusion can be configured as a circular truncated cone. The insulating support 25a is provided with a positioning hole 215a, which can be a circular hole. The positioning protrusion of the chip extends into the positioning hole 215a of the insulating support 25a.

[0158]

[0159] ​The positioning protrusion of the chip and the positioning hole 215a of the insulating support 25a are matched with each other, and the alignment between the chip and the insulating support 25a is more accurate.

[0160] In an illustrative embodiment, the electric control box 2a further comprises an insulating cover plate 26a. The insulating cover plate 26a is made of insulating material, which can be engineering plastic. The insulating cover plate 26a covers the side of the insulating support 25a away from the circuit board 271a, and the heat dissipation bottom plate 22a and the heat dissipation cover plate 23a are clamped between the insulating cover plate 26a and the insulating support 25a. The insulating cover plate 26a and the insulating support 25a enclose a mounting cavity, which accommodates the heat dissipation bottom plate 22a and the heat dissipation cover plate 23a. In this embodiment, the surface of the insulating support 25a towards the insulating cover plate 26a is recessed to form a first mounting groove 216a, and the heat dissipation bottom plate 22a is arranged in the first mounting groove 216a. The surface of the insulating cover plate 26a towards the insulating support 25a is recessed to form a second mounting groove (not shown in the figure), and the heat dissipation cover plate 23a is arranged in the second mounting groove. The inner wall of the first mounting groove 216a and the inner wall of the second mounting groove enclose the mounting cavity that accommodates the heat dissipation bottom plate 22a and the heat dissipation cover plate 23a.

[0161] In this way, the insulating support 25a and the insulating cover plate 26a enclose a mounting cavity, and the heat dissipation bottom plate 22a, the heat dissipation cover plate 23a and the cooling pipe 24a are all arranged in the mounting cavity. The insulating support 25a and the insulating cover plate 26a can be heat-insulated to block heat in the mounting cavity, so that most of the heat can only be output from the cooling pipe 24a to the box body 21a, preventing the temperature of other areas in the box body 21a from being too high.

[0162] In an illustrative embodiment, the insulating cover plate 26a and the insulating support 25a are detachably connected. The insulating cover plate 26a and the insulating support 25a can be snap-connected. The side wall of the insulating cover plate 26a is provided with a plurality of hooks 261a, which extend towards the insulating support 25a. The side wall of the insulating support 25a is provided with a plurality of protrusions 213a, and the plurality of hooks 261a respectively hook the plurality of protrusions 213a, thereby realizing the snap connection between the insulating cover plate 26a and the insulating support 25a.

[0163] The heat dissipation bottom plate 22a and the heat dissipation cover plate 23a are detachably connected. The heat dissipation bottom plate 22a and the heat dissipation cover plate 23a can be connected by screws.

[0164] In this way, the heat dissipation bottom plate 22a is connected with the heat dissipation cover plate 23a, and the heat dissipation bottom plate 22a and the heat dissipation cover plate 23a can clamp the cooling pipe 24a, so that the gap between the heat dissipation bottom plate 22a and the cooling pipe 24a and the gap between the heat dissipation cover plate 23a and the cooling pipe 24a are as small as possible, and the heat transfer efficiency is improved. At the same time, the insulation cover plate 26a is connected with the insulation support 25a, and can fix the heat dissipation bottom plate 22a, the cooling pipe 24a and the heat dissipation cover plate 23a. Since the heat dissipation bottom plate 22a and the heat dissipation cover plate 23a are detachably connected and the insulation cover plate 26a and the insulation support 25a are detachably connected, when overhauling, the insulation cover plate 26a and the insulation support 25a can be first disassembled, and then the heat dissipation bottom plate 22a and the heat dissipation cover plate 23a are disassembled, so that the cooling pipe 24a can be separated from other parts of the electric control box, and the disassembly is more convenient.

[0165] In an illustrative embodiment, as shown in Figure 18 The box body 21a includes a box body 211a and a box cover 212a. The box body 211a is detachably connected to the shell 1 and is arranged outside the shell 1. The box body 211a can be detachably connected to the outer side of the second plate member 113, that is, the electric control box 2a is arranged on the outer side wall of the first shell 11. The bottom of the box body 211a can be provided with a plurality of hooks 217a, and the second plate member 113 is provided with a plurality of hanging holes 1131. The hanging holes 1131 penetrate through the second plate member 113. The plurality of hooks 217a are respectively hung on the second plate member 113 by penetrating through the plurality of hanging holes 1131, so that the box body 211a can be hung on the second plate member 113 through the hooks 217a. The second plate member 113 and the box body 211a are further provided with screw connection. When it is needed to separate the box body 211a from the second plate member 113, only the screws connecting the second plate member 113 and the box body 211a are unscrewed, and then the box body 211a is lifted up to make the hooks 217a disengage from the hanging holes 1131, so that the box body 211a can be disassembled.

[0166] The box cover 212a covers the box body 211a and encloses a cavity with the box body 211a. The box cover 212a is located on the side of the box body 211a away from the shell 1. The box cover 212a is detachably connected to the box body 211a. The box body 211a and the box cover 212a can be screw connected.

[0167] The control board 27a, the insulation support 25a, the insulation cover plate 26a, the heat dissipation bottom plate 22a and the heat dissipation cover plate 23a are all arranged in the cavity enclosed by the box cover 212a and the box body 211a. The circuit board 271a is connected to the side of the box body 211a facing the box cover 212a. The circuit board 271a and the box body 211a can be detachably connected, for example, screw connected. The insulation support 25a is arranged on the board surface of the circuit board 271a facing the box cover 212a.

[0168] In this way, when the electric control box 2a is disassembled for maintenance, the cover 212a can be dismounted from the box body 21a, the insulating cover plate 26a can be dismounted from the insulating support 25a, the heat dissipation cover plate 23a can be dismounted from the heat dissipation bottom plate 22a, the cooling pipe 24a can be removed from the heat dissipation cover plate 23a, and finally the box body 21a can be dismounted from the shell 1, which is convenient for dismounting. Meanwhile, the electric control box 2a is arranged outside the shell 1 and is not affected by the temperature change in the shell 1, which is more stable.

[0169] In an illustrative embodiment, as shown in Figure 18 the box body 211a of the electric control box 2a is arranged on the outer side wall of the first shell 11. The box body 211a or the cover 212a is provided with a first notch 2121a near the side wall of the bottom plate 13. The first notch 2121a can be arranged on the side of the cover 212a close to the box body 211a, and the opening of the first notch 2121a faces the box body 211a; or the first notch 2121a can be arranged on the side of the box body 211a close to the cover 212a, and the opening of the first notch 2121a faces the cover 212a. The two ends of the cooling pipe 24a can extend out of the box body 21a from the first notch 2121a after being bent relative to the cooling channel 20a. The compressor 6 and the throttling element are arranged on the side of the second heat exchanger 5 away from the electric control box 2a. The side of the second heat exchanger 5 away from the compressor 6 is close to the side wall of the second cavity 120.

[0170] As shown in Figure 21 the kitchen air conditioner 100 further comprises a first refrigerant pipe 91 and a second refrigerant pipe 92. The two ends of the first refrigerant pipe 91 are connected to one end of the cooling pipe 24a and the second heat exchanger 5, respectively. The two ends of the second refrigerant pipe 92 are connected to the other end of the cooling pipe 24a and the throttling element or the second heat exchanger 5, respectively. The first refrigerant pipe 91 and the second refrigerant pipe 92 extend along the upper surface of the bottom plate 13. The first refrigerant pipe 91 extends from the end of the second heat exchanger 5 close to the compressor 6 to the second area 133 of the bottom plate 13, then extends to the groove bottom of the accommodation groove 14 from the second area 133, extends along the groove bottom to the electric control box 2a, and finally extends to the bottom of the electric control box 2a to be connected to one end of the cooling pipe 24a. The second refrigerant pipe 92 extends from the throttling element or the second heat exchanger 5 to the second area 133 of the bottom plate 13, then extends to the groove bottom of the accommodation groove 14 from the second area 133, extends along the groove bottom to the electric control box 2a, and finally extends to the bottom of the electric control box 2a to be connected to the other end of the cooling pipe 24a.

[0171] Thus, when the control box 2a or the control panel 27a is repaired or disassembled, after the cover 212a, the heat dissipation cover plate 23a and the insulating cover plate 26a are disassembled, the cooling pipe 24a is exposed, and after the connection between the box body 211a and the shell 1 is released, the control panel 27a is exposed or the box body 211a and the control panel 27a are pulled out from the gap between the cooling pipe 24a and the shell 1 by bending the cooling pipe 24a to the outside of the shell 1, which is more convenient for repair and disassembly. Alternatively, after the cover 212a is disassembled, the connection between the insulating support 25a and the control panel 27a is released, and the control panel 27a is exposed or the box body 211a and the control panel 27a are pulled out from the gap between the cooling pipe 24a and the shell 1 by bending the cooling pipe 24a with the insulating support 25a and other components to the outside of the shell 1, which is more convenient for repair and disassembly. At the same time, the pipes in the bottom of the part of the first refrigerant pipe 91 and the part of the second refrigerant pipe 92 along the gap 14 make full use of the space in the bottom of the gap 14, reduce the space occupation of the first refrigerant pipe 91 and the second refrigerant pipe 92 in the first cavity 110 and the second cavity 120, and make the kitchen air conditioner 100 more compact and the layout more reasonable. The first gap 2121a is arranged on the side of the box body 21a close to the bottom plate 13, and the two ends of the cooling pipe 24a extend out of the box body 21a from the first gap 2121a, which is convenient for connecting with the first refrigerant pipe 91 and the second refrigerant pipe 92 extending along the bottom plate 13.

[0172] In an illustrative embodiment, as shown in Figure 18 , 21 The electric control box 2a is arranged on the outer side wall of the first shell 11 adjacent to the gap 14, and the first gap 2121a is arranged on the cover 212a, the opening of the first gap 2121a communicates the space between the cover 212a and the box body 211a, and the two ends of the cooling pipe 24a extend out of the first gap 2121a of the cover 212a and extend away from the box body 211a, and then are connected to the first refrigerant pipe 91 and the second refrigerant pipe 92 below the gap 14. In this way, the cooling pipe 24a can be deformed more in the direction away from the shell 1, which is convenient for repairing and disassembling the electric control box 2a or the control panel 27a.

[0173] In an illustrative embodiment, as shown in Figure 21 The one end of the second heat exchanger 5 close to the compressor 6 is used to connect the refrigerant pipe. That is, one end of the first refrigerant pipe 91 is connected to the one end of the second heat exchanger 5 close to the compressor 6, and the refrigerant pipe adjacent to the second heat exchanger 5 and the compressor 6 is connected to the one end of the second heat exchanger 5 close to the compressor 6. The one end of the second heat exchanger 5 away from the compressor 6 is close to the side wall of the second cavity 120.

[0174] In this way, the second heat exchanger 5 is connected to the refrigerant pipe near the one end of the compressor 6, so that the other end of the second heat exchanger 5 can be as close to the side wall of the second cavity 120 as possible, and thus the kitchen air conditioner 100 can be more compact. Meanwhile, since the second heat exchanger 5 is connected to the refrigerant pipe near the one end of the compressor 6, and all the U-shaped heat exchange pipes 51 are arranged at the other end of the second heat exchanger 5, the processing difficulty of the second heat exchanger 5 can be reduced.

[0175] In an exemplary embodiment, at least a portion of the first refrigerant pipe 91 and at least a portion of the second refrigerant pipe 92 extend along the pipe routing passage.

[0176] In this way, the protective cover 141 can separate the keel passing through the accommodation slot 14 from the first refrigerant pipe 91 and the second refrigerant pipe 92, so as to prevent the first refrigerant pipe 91 and the second refrigerant pipe 92 from being damaged due to being pressed by the keel.

[0177] In an exemplary embodiment, as shown in Figure 8 23 The kitchen air conditioner 100 further comprises a weak current cable, a strong current cable and a first wire routing member la. One end of the strong current cable and the weak current cable are connected to the control panel 27a of the electric control box, and the other end of the strong current cable and the weak current cable are used to connect to the electric devices controlled by the electric control box. The weak current cable transmits a low voltage, for example, below 36V. The strong current cable transmits a high voltage, for example, above 36V.

[0178] As shown in Figure 23 The first wire routing member la is made of an insulating material, for example, plastic, and has insulating property. The first wire routing member la is arranged in the first cavity 110 of the shell 1. One end of the first wire routing member la is close to the electric control box 2a. The first wire routing member la is provided with a first wire routing groove 11a and a second wire routing groove 12a. The first wire routing groove 11a and the second wire routing groove 12a are arranged side by side. One end of the first wire routing groove 11a and the second wire routing groove 12a is close to the electric control box 2a. After the weak current cable extends out of the electric control box 2a, at least a portion of the weak current cable is routed along the first wire routing groove 11a. After the strong current cable extends out of the electric control box 2a, at least a portion of the strong current cable is routed along the second wire routing groove 12a. As shown in Figure 8 17 The electric control box 2a is provided with a weak current cable hole and a strong current cable hole. The weak current cable hole is in communication with one end of the first wire routing groove 11a, and the strong current cable hole is in communication with one end of the second wire routing groove 12a.

[0179] ​​In this way, at least a part of the weak current cable is arranged in the first routing groove 11a of the first routing member 1a, at least a part of the weak current cable is arranged in the first routing groove 11a of the first routing member 1a, the first routing member 1a separates the part of the weak current cable from the part of the strong current cable, and prevents the electric conduction between the strong current cable and the weak current cable. Meanwhile, the weak current cable and the strong current cable can be routed only by being inserted into the first routing groove 11a and the second routing groove 12a respectively, which can improve the assembly efficiency, and the weak current cable and the strong current cable can be quickly and safely detached from the first routing member 1a during maintenance.

[0180] In an illustrative embodiment, the first routing member 1a is configured in a strip shape. The first routing member 1a can be configured in an L-shaped structure. The first routing member 1a can extend along the top of the second plate member 113 to the top of one end of the partition plate 114, and then extend from the top of the one end of the partition plate 114 to the middle of the top of the partition plate 114. The first routing groove 11a and the second routing groove 12a both extend along the first routing member 1a from one end of the first routing member 1a to the other end of the first routing member 1a.

[0181] In this way, the first routing member 1a is configured in a strip shape, and the first routing groove 11a and the second routing groove 12a both extend along the first routing member 1a, so that the structure of the first routing member 1a is simpler, and the first routing member 1a occupies less space.

[0182] In an illustrative embodiment, the first routing groove 11a is provided with a first wire clamping portion 13a on the inner side wall. The first wire clamping portion 13a can be configured in a flat plate structure, and the first wire clamping portion 13a is parallel to the groove bottom of the first routing groove 11a. The first wire clamping portion 13a extends from one inner side wall of the first routing groove 11a to the other inner side wall, and there is a gap between the first wire clamping portion 13a and the other inner side wall. There is a certain spacing between the first wire clamping portion 13a and the first routing groove 11a, and the weak current cable passes through the space between the first wire clamping portion 13a and the groove bottom of the first routing groove 11a. Since the side of the weak current cable away from the groove bottom of the first routing groove 11a is pressed by the first wire clamping portion 13a, the weak current cable is difficult to be pulled out of the first routing groove 11a.

[0183] In an illustrative embodiment, a plurality of first wire clamping portions 13a are provided on the first routing member 1a, and the plurality of first wire clamping portions 13a are arranged in sequence along the first routing groove 11a. The first wire clamping portion 13a can be provided with three, two first wire clamping portions 13a are respectively provided at opposite ends of the first routing groove 11a, and the remaining one first wire clamping portion 13a is provided at the middle of the first routing groove 11a.

[0184] The plurality of first wire clamping portions 13a can more stably fix the weak current cable in the first routing groove 11a.

[0185] In an illustrative embodiment, the second clamping portion 14a is arranged on the inner side wall of the second wire slot 12a. The second clamping portion 14a can be configured as a flat plate structure, and the second clamping portion 14a is parallel to the slot bottom of the second wire slot 12a. The second clamping portion 14a extends from one inner side wall to the other inner side wall of the second wire slot 12a, and there is a gap between the second clamping portion 14a and the other inner side wall. There is a certain spacing between the second clamping portion 14a and the second wire slot 12a, and the strong power cable passes through the space between the second clamping portion 14a and the slot bottom of the second wire slot 12a. Since the strong power cable is pressed against the side of the slot bottom of the second wire slot 12a by the second clamping portion 14a, it is difficult for the strong power cable to come out of the second wire slot 12a.

[0186] In an illustrative embodiment, a plurality of second clamping portions 14a are arranged on the first wire arrangement 1a, and the plurality of second clamping portions 14a are arranged in sequence along the second wire slot 12a. There can be three second clamping portions 14a, two second clamping portions 14a are arranged at opposite ends of the second wire slot 12a, and the remaining one second clamping portion 14a is arranged in the middle of the second wire slot 12a.

[0187] The plurality of second clamping portions 14a can more stably fix the strong power cable in the second wire slot 12a.
