[0145] like Figures 1 to 3 As shown, Figures 1 to 3 The structure of a kitchen air conditioner 100 in this embodiment is shown. The kitchen air conditioner 100 includes a housing 1, a first fan 2, a second fan 4, a first heat exchanger 3, a second heat exchanger 5 and a compressor 6.

[0146] like Figures 4 to 7 As shown, a first cavity 110 and a second cavity 120 are provided in the housing 1. The first cavity 110 and the second cavity 120 are provided 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 configured as a substantially right hexahedron. A first air inlet 101, a first air outlet 102, a second air inlet 103 and a second air outlet 104 are provided on the housing 1. The first air inlet 101 is provided on the side wall of the first cavity 110. The first air inlet 101 is connected to the indoor space and is used to transport air into the first cavity 110. The first air outlet 102 is provided on the bottom wall of the first cavity 110. The first air outlet 102 can be configured as a straight strip. The first air outlet 102 is used to output the air input into the first cavity 110 from the first air inlet 101 to the first cavity 110. The second air inlet 103 is provided on the side wall of the second cavity 120. The second air inlet 103 is connected to the indoor space and is used to transport 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 input into 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.

[0147] The first fan 2 is connected to the housing 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. When the first fan 2 is in operation, it can inhale air from the first air inlet 211 and then output it from the first air outlet 213. 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. When the first fan 2 is in operation, it can inhale the air in the first cavity 110, and transport the air in the first cavity 110 to the outside of the housing 1 through the first air outlet 213 and the first air outlet 102 in sequence. After the first fan 2 inhales the air in the first cavity 110, the air pressure in the first cavity 110 is negative pressure, and the air outside the housing 1 enters the first cavity 110 from the first air inlet 101.

[0148] The first heat exchanger 3 is disposed in the first cavity 110. The first heat exchanger 3 may be disposed on a 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.

[0149] The second fan 4 may 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 suck the air of the indoor space into the second cavity 120, and then transport it 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. When the second fan 4 is in operation, it can suck air from the second air inlet 411 and then output it from the second air outlet 413. 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 connect to the outdoor space. When the second fan 4 is in operation, it can inhale the air in the second cavity 120, and transport the air in the second cavity 120 to the outside of the housing 1 through the second air outlet 413 in sequence. After the second fan 4 inhales the air in the second cavity 120, the air pressure in the second cavity 120 is negative pressure, and the air outside the housing 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 housing 1, and the air output from the second air outlet 104 of the second cavity and entering the second fan 4 is transported to the side of the housing 1 through the second air outlet 413.

[0150] The second heat exchanger 5 is disposed in the second cavity 120. The second heat exchanger 5 may be disposed 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.

[0151] The compressor 6 may be arranged in the housing 1. The compressor 6 may be arranged in the first cavity 110 or in the second cavity 120. In the present embodiment, the compressor 6 is arranged in the second cavity 120. The compressor 6 is connected to the first heat exchanger 3 and the second heat exchanger 5 through the refrigerant pipe 9. The refrigerant pipe 9, the first heat exchanger 3 and the second heat exchanger 5 may be pre-filled with refrigerant. The compressor 6 can drive the refrigerant to circulate between the first heat exchanger 3 and the second heat exchanger 5, so that heat is transferred between the first heat exchanger 3 and the second heat exchanger 5 with 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 the heat of 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 transported from the first air outlet 102 of the first cavity to the indoor is cold air. Correspondingly, the temperature of the air flowing through the second cavity increases, and the air transported from the second cavity to the outdoor is hot air.

[0152] In this way, the first fan 2, the second fan 4, the first heat exchanger 3, the second heat exchanger 5 and the compressor 6 are all installed on the housing 1, and the kitchen air conditioner 100 is constructed as an integrated machine, and the structure of this kitchen air conditioner 100 is simple, and can achieve efficient production and quick installation. At the same time, after the housing 1 of this kitchen air conditioner 100 is embedded and 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. The first air inlet 101, the second air inlet 103, and the second air outlet 104 of the housing 1 of the kitchen air conditioner 100 can be hidden above the ceiling, which is more beautiful. The second fan 4 transports the air output from the second cavity 120 to the side of the housing 1, which is convenient for the outdoor exhaust duct to be connected to the kitchen air conditioner 100 from the side of the housing 1, and will not increase the installation space required for the kitchen air conditioner 100 in the vertical direction. The first air outlet 102 of the kitchen air conditioner 100 supplies air to the bottom of the housing 1, which can quickly adjust the temperature of the space under the ceiling and improve the user experience.

[0153] In an exemplary embodiment, at least a portion of the first air inlet 101 is disposed on the side wall of the first cavity 110 facing away from the second cavity 120, and the area of ​​the first air inlet 101 disposed on the side wall of the first cavity 110 facing away from the second cavity 120 accounts for more than 80 percent of the area of ​​the side wall of the first cavity 110 facing away from the second cavity 120. Figure 1 , 2 As shown in Figures 1 and 8, other parts of the first air inlet 101 can be arranged on other side walls adjacent to the side wall of the first cavity 110 facing away from the second cavity 120, so as to increase the air inlet area. At least part of the second air inlet 103 is arranged on the side wall of the second cavity 120 facing away from the first cavity 110, and the area of ​​the second air inlet 103 arranged on the side wall of the second cavity 120 facing away from the first cavity 110 accounts for more than 80% of the area of ​​the side wall of the second cavity 120 facing away from the first cavity 110.

[0154] In this way, at least part of the first air inlet 101 and at least part of the second air inlet 103 are respectively located on opposite sides of the housing 1, and air is taken in from opposite sides of the housing 1, so as to avoid mutual influence between the air intake of the first cavity 110 and the second cavity 120, thereby reducing noise. The first air inlet 101 and the second air inlet 103 can directly take in air from the outside of the housing 1, or can be connected with an air intake duct. When one of the first air inlet 101 and the second air inlet 103 is connected with the air intake duct, the air intake duct will not block the other of the first air inlet 101 and the second air inlet 103, thereby affecting the air intake. In addition, the first air inlet 101 and the second air inlet 103 can be set larger, and the air intake volume of the first cavity 110 and the second cavity 120 can be increased accordingly, so that the size of the housing 1 of the kitchen air conditioner 100 can be reduced while ensuring the heat exchange efficiency of the first heat exchanger 3 and the second heat exchanger 5, so that the structure of the kitchen air conditioner 100 is more compact.

[0155] In an illustrative embodiment, Figure 1 , 2 As shown, the top of the housing 1 is recessed downward to form a clearance groove 14. The clearance groove 14 can be set as a straight groove. The clearance groove 14 extends from one side of the housing 1 to the other side of the housing 1, and the clearance groove 14 passes through the housing 1 in the horizontal direction. The depth of the clearance groove 14 can be 80% to 95% of the size of the housing 1 in the vertical direction. The first cavity 110 and the second cavity 120 are respectively 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.

[0156] like Fig.24 As shown, the ceiling 1000 includes a keel 1100 as a supporting structure and a splicing decorative panel 1200 installed on the keel 1100. There are multiple splicing decorative panels 1200, and the multiple splicing decorative panels 1200 are connected to the keel 1100, and the multiple splicing decorative panels 1200 are distributed in a matrix shape. Visually, the ceiling 1000 is a horizontally arranged flat plate.

[0157] The keel 1100 includes a plurality of first keels 1101, which are arranged in parallel and located on the same horizontal plane, and two adjacent first keels 1101 are spaced apart. The spacing between two adjacent first keels 1101 is the same. In other schemes, the keel also includes a plurality of second keels 1102, which extend in a direction perpendicular to the first keel. Two adjacent second keels 1102 are spaced apart. The spacing between two adjacent second keels 1102 is the same. The plurality of first keels and the plurality of second keels 1102 are constructed as a mesh structure, and each spliced ​​decorative panel covers a mesh in the mesh structure. The shape of the spliced ​​decorative panel 1200 is not limited, and can be a square shape or a hexagonal shape, etc. As for the method of fixing the keel 1100 on the wall 2000, there is no restriction here. In some solutions, the end of the keel 1100 is fixed to the wall, and the kitchen roof is provided with a hanging structure, and the keel 1100 is fixed on the hanging structure, so that the entire ceiling 1000 is hung.

[0158] According to the existing technical solution, when the integrated kitchen air conditioner is installed in front, it is necessary to install the body first and then install the ceiling. Or install part of the keel on the ceiling first, then hoist the body, and install the remaining keel and spliced ​​decorative panels in between. When the integrated kitchen air conditioner is installed in the rear, due to the large size of the integrated kitchen air conditioner, it is usually necessary to remove part of the spliced ​​decorative panels and keels for installation. When the kitchen air conditioner needs to be cleaned or maintained, at least part of the spliced ​​decorative panels need to be removed. If the machine needs to be disassembled for maintenance, the keel on the ceiling also needs to be removed. This makes the cleaning and maintenance of the kitchen air conditioner very time-consuming and labor-intensive, and the operation is cumbersome.

[0159] The present application solution can solve the above problem. Since the top of the housing 1 of the kitchen air conditioner 100 is provided with a clearance groove 14, the clearance groove 14 can be passed through by the first keel 1101 or the second keel 1102. When installing the kitchen air conditioner 100, it is only necessary to align the opening of the clearance groove 14 with the first keel 1101 below the ceiling, and then raise the height of the kitchen air conditioner 100 so that the first keel 1101 enters the clearance groove 14 until the first keel 1101 is located at the bottom of the clearance groove 14. Finally, the kitchen air conditioner 100 is fixed, such as the kitchen air conditioner 100 is fixed by hoisting to complete the installation. During the installation of the kitchen air conditioner 100, it is not necessary to remove the installed keel. After the kitchen air conditioner 100 is installed, except for the end of the bottom end of the housing 1, the other parts of the housing 1 can be hidden in the interlayer space above the ceiling, which is more beautiful. Accordingly, when the kitchen air conditioner 100 needs to be repaired, it is only necessary to release the fixing of the kitchen air conditioner 100 and vertically lower the height of the kitchen air conditioner 100 to disassemble the kitchen air conditioner 100, and it is not necessary to disassemble the installed keel during the disassembly process of the kitchen air conditioner 100. Compared with the prior art solutions, the kitchen air conditioner of the embodiment of the utility model reduces the repair steps and time, and improves the maintenance efficiency.

[0160] In an illustrative embodiment, 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 a plate-like structure, which may be a flat plate. The chassis 13 may be generally a rectangular plate. One plate surface of the chassis 13 faces upward. Figure 5 , 14 As shown, the first area 131, the second area 133 and the connecting area 132 are arranged on the upward plate surface of the chassis 13. The first area 131 and the second area 133 are both roughly rectangular areas. The connecting area 132 is arranged between the first area 131 and the second area 133. The connecting area 132 connects the first area 131 and the second area 133. The connecting area 132 can be configured as a straight strip, and the first area 131 and the second area 133 are on opposite sides of the width direction of the connecting area 132. The first air outlet 102 is arranged on the first area 131. The first air outlet 102 vertically penetrates the chassis 13.

[0161] The first housing 11 is disposed above the chassis 13. The first housing 11 covers the first area 131 of the chassis 13. The first housing 11 and the first area 131 of the chassis 13 enclose a first cavity 110. The first air inlet 101 is disposed on a side wall of the first housing 11.

[0163] The first shell 11 and the second shell 12 are spaced apart from each other, and the through slot 14 is located between the first shell 11 and the second shell 12 and above the connection area 132 .

[0164] In an illustrative embodiment, Figure 1 , 2 As shown in Figures 3 and 4, the first shell 11 includes a partition 114, a first plate 112, a second plate 113 and a first top plate 111. The partition 114 can be constructed as a rectangular plate. The partition 114 is arranged vertically. The partition 114 extends upward from the boundary between the first area 131 and the connection area 132 of the chassis 13. The partition 114 and the chassis 13 can be connected by screws, welding or riveting. In this embodiment, a flange can be provided at the bottom end of the partition 114 close to the chassis 13, and the flange is against the chassis 13, and the flange is connected to the chassis 13 by screws.

[0165] like Fig.10 As shown, the first plate 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 area 131 of the chassis 13 facing away from the connection area 132. The first side plate 1121 is perpendicular to the chassis 13. The first side plate 1121 may be parallel to the partition 114. A first air inlet 101 is provided on the first side plate 1121. The first air inlet 101 provided on the first side plate 1121 may be a rectangular opening. The area of ​​the first air inlet 101 provided on the first side plate 1121 may be slightly smaller than the area of ​​the first side plate 1121. The first air inlet 101 may be provided sufficiently large. The second side plate 1122 is perpendicular to the chassis 13. The second side plate 1122 extends from one end of the first side plate 1121 along the edge of one side of the first area 131 to one end of the partition 114. The extension direction of the second side plate 1122 is substantially perpendicular to the plate surface of the partition 114. The second side plate 1122 may be provided with a side air inlet as a part of the first air inlet 101. The first side plate 1121 and the second side plate 1122 are both screwed to the chassis 13. In this embodiment, a flange may be provided on one side of the partition plate 114 close to the second side plate 1122, the flange abutting against the second side plate 1122, and the flange and the second side plate 1122 are screwed.

[0166] like Fig.14As shown, the second plate 113 is constructed as a flat plate, which can be a rectangular flat plate. The second plate 113 is arranged at the edge of the first area 131 facing away from the second side plate 1122. The second plate 113 is arranged vertically. The second plate 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 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 114. The first side plate 1121 and the partition 114 are connected to the second side plate 1122 by screws, welding or riveting. In this embodiment, the second plate 113 and the chassis 13 are constructed as an integrally formed structure, which can reduce the assembly steps and enhance the connection strength between the second plate 113 and the chassis 13. The second plate 113 can be more firmly connected to the chassis 13.

[0167] like Figure 1 As shown, the first top plate 111 is arranged above the first area 131 of the chassis 13, and there is a gap between the first top plate 111 and the chassis 13. The shape of the first top plate 111 is the same as the shape of the first area 131. The first top plate 111 is parallel to the chassis 13. The first top plate 111 is connected to the partition 114, the first side plate 1121, the second side plate 1122 and the end of the second plate 113 facing away from the chassis 13. The partition 114, the first side plate 1121, the second side plate 1122, the second plate 113 and the first top plate 111 can be welded, screwed or riveted. In this embodiment, a flange can be provided at one end of the partition 114 close to the first top plate 111, and the flange is screwed to the first top plate 111.

[0168] In this way, the chassis 13, the partition 114, the first plate 112, the second plate 113 and the first top plate 111 enclose a first cavity 110, and the first shell 11 is spliced ​​together by the partition 114, the first plate 112, the second plate 113 and the first top plate 111, with a simple structure, easy processing and low manufacturing cost.

[0169] In an illustrative embodiment, Figure 8 As shown, the first heat exchanger 3 is constructed as a U-shaped heat exchanger. The first heat exchanger 3 extends from one end of the partition 114 along the second plate 113, the first side plate 1121 and the second side plate 1122 to the other end of the partition 114. The two ends of the first heat exchanger 3 are respectively close to the two ends of the partition 114. The first heat exchanger 3 and the partition 114 enclose an internal cavity. The bottom end of the first heat exchanger 3 is connected to the bottom plate 13.

[0170] like Figure 8 As shown, the first fan 2 is disposed in the internal cavity enclosed by the first heat exchanger 3 and the partition 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 chassis 13.

[0171] The first heat exchanger 3 is constructed in a U shape, has a large contact area with the air, and has a high heat exchange efficiency. Since the first fan 2 is arranged in the internal cavity enclosed by the first heat exchanger 3 and the partition 114, the layout is compact and the first cavity 110 can be reduced accordingly, so that the overall volume of the kitchen air conditioner 100 is smaller.

[0172] In an illustrative embodiment, Fig. 9 As shown, the first fan 2 includes a first air duct member 21, a first wind wheel 22 and a first motor 23. The first air duct member 21 includes 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 both penetrate the connecting shell 215 and are connected to the first air outlet 102 on the chassis 13. The first air inlets 211 of the two first volutes 214 are both connected to the internal cavity enclosed by the first heat exchanger 3 and the partition 114.

[0173] The two first wind wheels 22 are respectively arranged in the first air duct 212 of the two first volutes 214. The first wind wheel 22 can be a centrifugal wind wheel. The two first wind wheels 22 are coaxially arranged. The first motor 23 is arranged between the two first wind wheels 22, and the two ends of the main shaft of the first motor 23 are respectively connected to the two first wind wheels 22. The first motor 23 can drive the two first wind wheels 22 to rotate synchronously. When the first wind wheel 22 rotates, it can drive the air in the first air duct 212 of the first volute 214 where it is located to flow from the first air inlet 211 to the first air outlet 213. The first motor 23 can be installed on the connecting shell 215, and the first air duct member 21, the two first wind wheels 22 and the first motor 23 form a module.

[0174] In this way, the two first wind wheels 22 of the first fan 2 rotate synchronously to supply air, and the air volume supplied is larger. At the same time, the first motor 23 is arranged between the two first wind wheels 22 and the two first volutes 214, so that the structure of the first fan 2 is more compact, the installation space required for the first fan 2 is smaller, and the casing 1 can be set smaller.

[0175] Each first volute 214 may be provided with first air inlets 211 on both sides to increase air volume. The U-shaped heat exchanger may be arranged around the first fan 2, and the two first air inlets 211 of the two first volutes 214 facing away from each other are respectively oriented toward the two ends of the U-shaped heat exchanger.

[0176] In an illustrative embodiment, Fig. 9As shown, a male buckle 216 is provided at the bottom of the first air duct member 21. Two male buckles 216 can be provided, and the two male buckles 216 are respectively provided on one side of the two first volutes 214 close to the bottom plate 13. Fig.14 As shown, the first area 131 of the chassis 13 is provided with female buckles 139. The number of the female buckles 139 is the same as the number of the male buckles 216. The female buckles 139 are arranged in a one-to-one correspondence with the male buckles 216. Each male buckle 216 is plugged into the corresponding female buckle 139 to achieve a snap-on connection between the first air duct member 21 and the chassis 13.

[0177] The first air duct member 21 and the chassis 13 are connected by snap-fit ​​connection, so that the assembly between the first fan 2 and the chassis 13 is easier and the assembly speed is improved.

[0178] In an illustrative embodiment, Figure 3 , 8 As shown, the second housing 12 includes a third plate 122, a second top plate 121 and a fourth plate 123. The third plate 122 includes a third side plate 1221 and a fourth side plate 1222. The third side plate 1221 is configured as a plate-like structure perpendicular to the chassis 13. The second air inlet 103 is arranged on the third side plate 1221. The third side plate 1221 extends upward from the edge of the second area 133 of the chassis 13 facing away from the connection area 132 of the chassis 13. The fourth side plate 1222 is configured as a plate-like structure perpendicular to the chassis 13 and the third side plate 1221. The fourth side plate 1222 is a fourth side plate 1222 extending from one end of the third side plate 1221 along the edge of the second area 133 to the connection area 132.

[0179] like Fig.14 As shown, the fourth plate 123 is configured as a flat plate extending vertically. The fourth plate 123 can be configured as a rectangular plate. The fourth plate 123 is perpendicular to the chassis 13 and extends upward from the edge of the second area 133 of the chassis 13 facing away from the fourth side plate 1222. One side of the fourth plate 123 is connected to the side of the third side plate 1221 facing away from the fourth side plate 1222. The fourth side plate 1222 can be perpendicular to the third side plate 1221. The fourth plate 123 and the chassis 13 can be an integrally formed structure.

[0180] The second top plate 121 is disposed above the second area 133 of the bottom plate 13. The shape of the second top plate 121 may be the same as that of the second area 133. The second top plate 121 is parallel to the bottom plate 13. The second top plate 121 connects the third side plate 1221, the fourth side plate 1222, and an end of the fourth plate 123 facing away from the bottom plate 13.

[0181] like Figure 5 , 7As shown, the second air outlet 104 of the second shell 12 is enclosed by the fourth side plate 1222 , the fourth plate 123 , the second top plate 121 and an end of the second area 133 of the bottom plate 13 facing away from the third side plate 1221 .

[0182] like Fig.12 , 13 As shown, the second fan 4 includes a second air duct member 41, a second wind wheel 42 and a second motor 43. The second air duct member 41 is provided with a second air inlet 411, a second air outlet 413 and a second air duct 412. The second wind wheel 42 may be a centrifugal wind wheel. The second air duct 412 extends from the second air inlet 411 to the second air outlet 413. The second wind wheel 42 is arranged in the second air duct 412. The body of the second motor 43 is connected to the second air duct member 41. The main shaft of the second motor 43 is connected to the second wind wheel 42. The second motor 43 can drive the second wind wheel 42 to rotate, and when the second wind wheel 42 rotates, it can drive the air in the second air duct 412 to flow from the second air inlet 411 to the second air outlet 413. The second air duct member 41 abuts against the fourth side plate 1222, the fourth plate member 123 and the second top plate 121 at one end facing away from the third side plate 1221, and the second air duct member 41 also abuts against the chassis 13. In this way, the second air duct member 41 can cover the second air outlet 104 of the second housing 12. The second air inlet 411 on the second air duct member 41 is configured to be connected to the second air outlet 104. The second air outlet 413 is configured to be connected to 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 outdoors. The second air outlet 413 can be connected to the outdoor space through the outdoor exhaust duct.

[0183] like Figure 5 As shown, the clearance groove 14 is formed 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 housing 11 .

[0184] The second heat exchanger 5 is disposed in the second cavity 120 and sandwiched between the second air duct member 41 and the third side plate 1221. The opposite sides of the second heat exchanger 5 are respectively 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. 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.

[0185] 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. At the same time, the second air duct member 41 also serves as a side wall of the make way slot 14, which can reduce the size of the kitchen air conditioner 100 in the width direction of the make way slot 14, making the volume of the kitchen air conditioner 100 smaller.

[0186] In an illustrative embodiment, Fig.14 As shown, the second area 133 of the chassis 13 is provided with a clearance opening 1331. The clearance opening 1331 vertically penetrates the chassis 13. The clearance opening 1331 can be configured as a rectangular opening.

[0187] The second air duct member 41 of the second fan 4 partially extends into the clearance opening 1331. The lower surface of the portion of the second air duct member 41 extending into the clearance opening 1331 is flush with the lower surface of the chassis 13, or the portion of the second air duct member 41 extending into the clearance opening 1331 can pass through the clearance opening 1331 so that its lower surface slightly protrudes from the lower surface of the chassis 13.

[0188] In this way, the second air duct member 41 of the second fan 4 can partially extend into the clearance opening 1331, which is beneficial to increase the size of the second fan 4 to increase the air volume of the second fan 4 or reduce the thickness of the kitchen air conditioner 100 in the vertical direction.

[0189] In an illustrative embodiment, Fig.12 , 13 As shown, 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 constructed in a flat plate shape. The first plate body 414 extends from the boundary between the second area 133 and the connection area 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 from each other. The second plate body 415 is arranged on a side of the first plate body 414 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 the 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 wind wheel 42 is disposed in the second volute 416, the second motor 43 is disposed in the second wind wheel 42, the body of the second motor 43 is connected to the first plate 414, and the main shaft of the second motor 43 is connected to the second wind wheel 42. The lower end of the second volute 416 extends into the clearance opening 1331 of the chassis 13. The structure of the second fan 4 is more compact.

[0190] In an illustrative embodiment, Fig.14 , 15As shown, the upper surface of the chassis 13 of the housing 1 is also provided with a water collecting trough 134, a water drawing trough 136 and a water diversion trough 135. The water collecting trough 134 is provided in the first area 131 of the chassis 13 and is located below the first heat exchanger 3. The shape of the water collecting trough 134 may be the same as the shape of the projection of the first heat exchanger 3 on the chassis 13, for example, both are constructed in a U shape. The water drawing trough 136 is provided in the second area 133 of the chassis 13 and is located below the second heat exchanger 5. The height of the bottom of the water collecting trough 134 may be greater than or equal to the height of the bottom of the water drawing trough 136. The water diversion trough 135 extends from the water collecting trough 134 to the water drawing trough 136. The water diversion trough 135 connects the water collecting trough 134 and the water drawing trough 136. The height of the bottom of the water drawing trough 135 may have a tendency to decrease in the direction extending from the water collecting trough 134 to the water drawing trough 136.

[0191] like Fig.14 , 16 As shown, the kitchen air conditioner 100 also includes a water pumping assembly 7. The water pumping assembly 7 is arranged on the chassis 13. The water pumping assembly 7 can be arranged in the second area 133. The water pumping assembly 7 includes a water pumping wheel 71 and a water pumping motor 72. The water pumping wheel 71 is constructed in a roughly disc shape. The water pumping wheel 71 is arranged above the chassis 13. The axis of the water pumping wheel 71 is arranged horizontally, and the water pumping wheel 71 at least partially extends into the water pumping tank 136. The water pumping motor 72 is transmission-connected to the water pumping wheel 71. The water pumping motor 72 can drive the water pumping wheel 71 to rotate.

[0192] When the kitchen air conditioner 100 is operated 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 water vapor in the air is pre-cooled and condensed on the surface of the first heat exchanger 3 to form condensed water droplets. The condensed water droplets on the surface of the first heat exchanger 3 are dripped into the water collecting tank 134 under the action of force and collected. The condensed water in the water collecting tank 134 flows into the water pumping tank 136 along the water guide tank 135. Since the water pumping wheel 71 extends into the water pumping tank 136, it can contact the condensed water in the water pumping tank 136. When the water pumping motor 72 drives the water pumping wheel 71 to rotate, the condensed water in the water pumping tank 136 can be thrown onto the second heat exchanger 5. When the kitchen air conditioner 100 is operated in the cooling mode, the surface temperature of the second heat exchanger 5 is relatively high, and heat can be released to the condensed water to evaporate the condensed water. When the condensed 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 condensed water is evaporated, the amount of condensed water in the water tank 136 can be reduced, preventing the condensed water in the chassis 13 from overflowing. Therefore, there is no need to set a drain pipe to lead the condensed water in the chassis 13 out of the kitchen air conditioner 100.

[0193] In an illustrative embodiment, Fig.14As shown, the kitchen air conditioner 100 further includes a water level switch 8. The water level switch 8 can be disposed in the water tank 136, or can be disposed at one end of the water tank 135 close to the water tank 136. The water level switch 8 can detect whether the water level in the water tank 136 or the water tank 135 reaches a preset threshold. The water level switch 8 is configured to shut down the compressor 6 after detecting that the water level in the water tank 136 or the water tank 135 reaches a preset threshold.

[0194] The preset threshold value can be set to be slightly less than the water level height at the water level switch 8 when the condensed water overflows from any one of the water-drawing tank 136, the water-collecting tank 134 and the water-introducing tank 135. When the water level in the water-drawing tank 136 or the water-introducing tank 135 reaches the preset threshold value, it means that the condensed water is at risk of overflowing the water-drawing tank 136, the water-collecting tank 134 or the water-introducing tank 135. At this time, the compressor 6 is turned off, so that the rate at which the first heat exchanger 3 produces condensed water decreases, and at the same time, the water-drawing wheel 71 is kept rotating to continuously consume the condensed water that has been produced, which can prevent the condensed water from overflowing when the air humidity is very high.

[0195] In an illustrative embodiment, Fig.14 As shown, a collecting tank 137 is also provided on the chassis 13. The collecting tank 137 is located below the second heat exchanger 5. The water tank 136 and the collecting tank 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 extension direction of the water tank 136 and the extension direction of the collecting tank 137 can be perpendicular to the flow direction of the air in the second cavity. The water tank 136 and the collecting tank 137 are separated by a baffle. A through hole 138 is provided on the baffle. The through hole 138 can be set as a through hole passing through the baffle, or it can be set as a notch passing through the baffle. The position of the through hole 138 can be higher than the bottom of the water tank 136. The through hole 138 can be set in the middle area of ​​the baffle in the vertical direction. The two ends of the through hole 138 are connected to the collecting tank 137 and the water tank 136 respectively.

[0196] In this way, after the water wheel 71 throws out the condensed water, part of the condensed water droplets will be driven by the airflow in the second cavity 120 to move a distance downstream of the airflow. At the same time, the condensed water that is not completely evaporated in the second heat exchanger 5 will also drip downward, and these condensed water droplets will also be driven by the airflow in the second cavity 120 to move a distance downstream of the airflow. Part of the condensed water droplets deflected by the airflow will not fall back into the water trough 136, but fall into the collection trough 137 to be collected, and then flow back from the collection trough 137 to the water trough 136, so as to prevent the condensed water from splashing to other areas of the chassis 13 due to the action of wind and causing the condensed water to overflow.

[0197] In an illustrative embodiment, the body of the water pumping motor 72 is disposed at the lower side of the second volute 416 and fixed to the chassis 13. In this embodiment, the second plate 415 is recessed toward the first plate 414 to form a clearance groove 4151, which is located at the lower side of the second volute 416, and the water pumping body is disposed in the clearance groove 4151.

[0198] Disposing the body of the water pumping motor 72 at the lower side of the second volute 416 can fully utilize the gap space between the volute and the chassis 13, making the structure of the kitchen air conditioner 100 more compact.

[0199] 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. These heat exchange tube rows are arranged in sequence along the air flow direction in the second cavity 120. The heat exchange channels of the plurality of heat exchange tube rows are connected in series in sequence according to the arrangement direction of the heat exchanger.

[0200] In this way, the second heat exchanger 5 is provided with more than four heat exchange tube rows for heat exchange, so the heat exchange efficiency is higher and the cooling capacity is larger in the cooling mode.

[0201] In an illustrative embodiment, Figure 8 As shown, the compressor 6 is arranged in the second cavity 120 of the housing 1. The compressor 6 is located at an end of the second fan 4 facing away from the second air outlet 413. The compressor 6 can be arranged at an end of the second fan 4 facing away from the fourth plate 123. The second heat exchanger 5 is arranged on a side of the second fan 4 facing away from the first cavity 110. The compressor 6 can be arranged at an end of the second heat exchanger 5 facing away from the fourth plate 123.

[0202] In this way, the compressor 6 is arranged at one end of the second fan 4, so that the compressor 6 and the pipeline connected thereto can fully utilize the space in the second cavity 120, making the kitchen air conditioner 100 more compact and smaller in size.

[0203] In an illustrative embodiment, Figures 17-20 As shown, the kitchen air conditioner 100 further includes an electric control box 2a and a throttling element. The electric control box 2a is connected to the first housing 11. The electric control box 2a may be connected to the second plate 113.

[0204] The electric control box 2a includes a box body 21a, a control board 27a, a heat dissipation base plate 22a, a heat dissipation cover plate 23a and a cooling pipe 24a. The box body 21a is constructed as a box-shaped structure. The box body 21a can be made of an insulating material, such as plastic. A chamber is provided in the box body 21a. The control board 27a is a logic control unit of the kitchen air conditioner 100.

[0205] The control board 27a is arranged in the chamber of the box body 21a. The control board 27a is a logic control unit of the kitchen air conditioner 100. A plurality of electrical components are arranged on the control board 27a. Some of the electrical components can be chips. The electrical components will generate heat when working.

[0206] The heat dissipation base plate 22a is made of metal material, such as aluminum or aluminum alloy. The heat dissipation base plate 22a has good thermal conductivity. The heat dissipation base plate 22a can be constructed as a rectangular plate. One plate surface of the heat dissipation base plate 22a is against the control board 27a.

[0207] The heat dissipation cover plate 23a is made of metal material, such as aluminum or aluminum alloy. The heat dissipation cover plate 23a has good thermal conductivity. The heat dissipation cover plate 23a covers the surface of the heat dissipation bottom plate 22a facing away from the control board 27a. The heat dissipation cover plate 23a and the heat dissipation bottom plate 22a enclose a cooling channel 20a. In this embodiment, Fig. 20 As shown, the heat dissipation bottom plate 22a is recessed inwardly toward the plate surface of the heat dissipation cover plate 23a to form a first groove 221a. The heat dissipation cover plate 23a is recessed inwardly toward the plate surface of the heat dissipation bottom plate 22a to form a second groove 231a. The first groove 221a and the second groove 231a have the same shape, and the first groove 221a and the second groove 231a are aligned with each other. The inner wall of the first groove 221a and the inner wall of the second groove 231a enclose a cooling channel 20a.

[0208] 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 the shape 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 is against the inner wall of the cooling channel 20a. The two ends of the cooling pipe 24a extend from between the heat dissipation cover plate 23a and the heat dissipation base plate 22a, and the end of the cooling pipe 24a can be bent relative to the cooling channel 20a, so as to facilitate the connection between the cooling pipe 24a and the refrigerant circulation system of the electric control box 2a vertically arranged on the air conditioner.

[0209] The throttling element may be an electronic expansion valve or a capillary tube. The throttling element may be arranged in the second cavity 120 and close to the compressor 6.

[0210] In some exemplary embodiments, the compressor 6, the second heat exchanger 5, the cooling pipe 24a, the throttling element and the first heat exchanger 3 are connected in sequence 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 also 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.

[0211] In this way, when the kitchen air conditioner 100 is working, the control panel 27a will generate heat and transfer the heat to the heat dissipation base plate 22a. Part of the heat on the heat dissipation base plate 22a is directly transferred to the cooling pipe 24a, and another part of the heat on the heat dissipation base 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. When the kitchen air conditioner 100 is in cooling mode, the compressor 6 compresses the refrigerant and then outputs the high-temperature and high-pressure refrigerant to the second heat exchanger 5. When the refrigerant flows through the second heat exchanger 5, the heat is transferred to the air flowing through the second cavity, and the refrigerant is cooled to a low-temperature refrigerant. The low-temperature refrigerant is transported from the second heat exchanger 5 to the cooling pipe 24a. When the refrigerant flows through the cooling pipe 24a, it absorbs the heat on the heat dissipation base plate 22a and the heat dissipation cover plate 23a, thereby bringing the heat emitted by the control board 27a out of the electronic control box 2a. After the refrigerant enters the throttling element, the throttling element throttles and reduces the pressure of the refrigerant. Then, the refrigerant is transported to the first heat exchanger 3, where it absorbs the heat of the air flowing through the first cavity and evaporates. The refrigerant flows back to the compressor 6 to complete a cycle.

[0212] In other exemplary embodiments, 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, and the cooling pipe 24a introduces 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 also 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 introduce the refrigerant from the main flow or branch flow of the second heat exchanger 5, and the refrigerant flows back to the second heat exchanger 5 before the subcooling section of the second heat exchanger 5 after passing through the cooling pipe 24a, and then flows to the subcooling section.

[0213] In this way, when the kitchen air conditioner 100 is working, the control panel 27a will generate heat and transfer the heat to the heat dissipation base plate 22a. Part of the heat on the heat dissipation base plate 22a is directly transferred to the cooling pipe 24a, and another part of the heat on the heat dissipation base plate 22a is first transferred to the heat dissipation cover plate 23a, and the heat dissipation cover plate 23a then transfers the heat to the cooling pipe 24a. When the kitchen air conditioner 100 is in cooling mode, the compressor 6 compresses the refrigerant and then outputs the high-temperature and high-pressure refrigerant to the second heat exchanger 5. When the refrigerant flows through the second heat exchanger 5, the heat is transferred to the air flowing through the second cavity, and the refrigerant is cooled to a low-temperature refrigerant. The refrigerant is transported from the second heat exchanger 5 to the cooling pipe 24a. When the refrigerant flows through the cooling pipe 24a, it absorbs the heat on the heat dissipation bottom plate 22a and the heat dissipation cover plate 23a, thereby bringing the heat emitted by the control board 27a out of the electric control box 2a. The refrigerant re-enters the second heat exchanger 5 for cooling, so that the cooling effect is not attenuated. After passing through the second heat exchanger 5, the refrigerant enters the throttling element, and the throttling element throttles and reduces the pressure of the refrigerant. After being transported to the first heat exchanger 3, the refrigerant absorbs the heat of the air flowing through the first cavity and evaporates. The refrigerant flows back to the compressor 6 to complete a cycle.

[0214] Thus, the refrigerant can take away the heat emitted by the control board 27a during the circulation process, and the heat dissipation is fast, ensuring that the temperature inside the electric control box 2a will not be too high, and the electrical components on the control board 27a can work stably at a suitable temperature. At the same time, the structure of the electric control box 2a is simple and easy to assemble and disassemble.

[0215] In an illustrative embodiment, Fig.19 As shown, both the cooling tube 24a and the cooling channel 20a are configured in a U shape.

[0216] The U-shaped cooling tube 24a has a larger contact area with the heat dissipation bottom plate 22a and the heat dissipation cover plate 23a, and the heat conduction between the cooling tube 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 tube 24a has a simple structure and is easy to manufacture.

[0217] In an illustrative embodiment, the control board 27a includes 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 may be a printed circuit board 271a. The chip is disposed on a surface of the circuit board 271a. The chip may be welded on the circuit board 271a. The circuit board 271a is fixed on the box body 21a. The circuit board 271a and the box body 21a may be connected by screws.

[0218] like Fig. 20As shown, the electric control box 2a also includes an insulating bracket 25a. The insulating bracket 25a is made of insulating material. The insulating bracket 25a can be constructed as a rectangular plate-like structure. A first through hole 214a is provided on the insulating bracket 25a. The first through hole 214a vertically penetrates the insulating bracket 25a. One board surface of the insulating bracket 25a is against the circuit board 271a. The insulating bracket 25a is connected to the circuit board 271a. The insulating bracket 25a and the circuit board 271a can be connected by screws. The extension direction of the first through hole 214a is perpendicular to the board surface of the circuit board 271a.

[0219] The heat dissipation base plate 22a is disposed on a side of the insulating support 25a facing away from the circuit board 271a, and is connected to the insulating support 25a. The heat dissipation base plate 22a may be covered on the board surface of the insulating support 25a facing 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 base plate 22a. The chip of the control board 27a passes through the first through hole 214a of the insulating support 25a, and the surface of the chip facing away from the circuit board 271a abuts against the heat dissipation base plate 22a.

[0220] In this way, the heat dissipation base plate 22a is arranged on the side of the insulating bracket 25a facing away from the circuit board 271a, and the insulating bracket 25a isolates the heat dissipation base plate 22a from the circuit board 271a of the control board 27a, preventing the heat dissipation base plate 22a from directly contacting the circuit board 271a and causing a short circuit on the circuit board 271a. At the same time, the chip is the main heat source on the control board 27a, and the chip can pass through the first through hole 214a to contact the heat dissipation base plate 22a. The heat dissipation base plate 22a can conduct the heat generated by the chip to the cooling pipe 24a to prevent the chip temperature from being too high.

[0221] In an illustrative embodiment, a positioning protrusion is provided on the side of the chip facing away from the circuit board 271a. The positioning protrusion can be configured as a truncated cone. A positioning hole 215a is provided on the insulating bracket 25a, and the positioning hole 215a can be a round hole. The positioning protrusion of the chip extends into the positioning hole 215a of the insulating bracket 25a.

[0222] The positioning protrusion of the chip cooperates with the positioning hole 215a of the insulating bracket 25a, so that the alignment between the chip and the insulating bracket 25a is more accurate.

[0223] In an illustrative embodiment, the electric control box 2a further includes an insulating cover plate 26a. The insulating cover plate 26a is made of insulating material, which may be engineering plastic. The insulating cover plate 26a covers the side of the insulating bracket 25a that faces away from the circuit board 271a, and the heat dissipation base plate 22a and the heat dissipation cover plate 23a are sandwiched between the insulating cover plate 26a and the insulating bracket 25a. The insulating cover plate 26a and the insulating bracket 25a enclose an installation cavity, which accommodates the heat dissipation base plate 22a and the heat dissipation cover plate 23a. In this embodiment, the plate surface of the insulating bracket 25a is recessed toward the insulating cover plate 26a to form a first mounting groove 216a, the heat dissipation base plate 22a is arranged in the first mounting groove 216a, the plate surface of the insulating cover plate 26a is recessed toward the insulating bracket 25a to form a second mounting groove (not shown in the figure), the heat dissipation cover plate 23a is arranged in the second mounting groove, and the inner wall of the first mounting groove 216a and the inner wall of the second mounting groove enclose an installation cavity for accommodating the heat dissipation base plate 22a and the heat dissipation cover plate 23a.

[0224] In this way, the insulating bracket 25a and the insulating cover plate 26a enclose an installation cavity, and the heat dissipation base plate 22a, the heat dissipation cover plate 23a and the cooling pipe 24a are all arranged in the installation cavity. The insulating bracket 25a and the insulating cover plate 26a can insulate to lock the heat in the installation cavity, so that most of the heat can only be output from the box body 21a from the cooling pipe 24a, thereby preventing the temperature of other areas in the box body 21a from being too high.

[0225] In an illustrative embodiment, the insulating cover plate 26a and the insulating bracket 25a are detachably connected. The insulating cover plate 26a and the insulating bracket 25a may be connected by a snap-on connection. A plurality of hooks 261a are provided on the side wall of the insulating cover plate 26a, and the hooks 261a extend toward the insulating bracket 25a. A plurality of protrusions 212a are provided on the side wall of the insulating bracket 25a, and the plurality of hooks 261a respectively hook the plurality of protrusions 212a, thereby realizing a snap-on connection between the insulating cover plate 26a and the insulating bracket 25a.

[0226] 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.

[0227] In this way, the heat dissipation base plate 22a is connected to the heat dissipation cover plate 23a, and the heat dissipation base plate 22a and the heat dissipation cover plate 23a can clamp the cooling tube 24a, so that the gap between the heat dissipation base plate 22a and the cooling tube 24a and between the heat dissipation cover plate 23a and the cooling tube 24a is as small as possible, thereby improving the heat transfer efficiency. At the same time, the insulating cover plate 26a is connected to the insulating bracket 25a, which can fix the heat dissipation base plate 22a, the cooling tube 24a, and the heat dissipation cover plate 23a. In addition, since the heat dissipation base plate 22a and the heat dissipation cover plate 23a are detachably connected and the insulating cover plate 26a and the insulating bracket 25a are detachably connected, during maintenance, the insulating cover plate 26a and the insulating bracket 25a can be disassembled first, and then the heat dissipation base plate 22a and the heat dissipation cover plate 23a can be disassembled, so that the cooling tube 24a can be separated from other parts of the electric control box, and disassembly is more convenient.

[0228] In an illustrative embodiment, Fig.18 As shown, the box body 21a includes a box body 211a and a box cover 212a. The box body 211a is detachably connected to the housing 1 and is arranged outside the housing 1. The box body 211a can be detachably connected to the outward side of the second plate 113, that is, the electric control box 2a is arranged on the outer side wall of the first housing 11. A plurality of hooks 217a can be arranged at the bottom of the box body 211a, and a plurality of hanging holes 1131 are arranged on the second plate 113. The hanging holes 1131 penetrate the second plate 113. The plurality of hooks 217a pass through the plurality of hanging holes 1131 respectively and are hung on the second plate 113, so that the box body 211a can be hung on the second plate 113 through the hooks 217a. A screw connection is also arranged between the second plate 113 and the box body 211a. When the box body 211a needs to be separated from the second plate 113, the screws connecting the second plate 113 and the box body 211a are unscrewed, and then the box body 211a is lifted up to make the hook 217a disengage from the hanging hole 1131, and the box body 211a can be disassembled.

[0229] The box cover 212a covers the box body 211a and encloses a chamber with the box body 211a. The box cover 212a is located on the side of the box body 211a facing away from the housing 1. The box cover 212a is detachably connected to the box body 211a. The box body 211a and the box cover 212a can be connected by screws.

[0230] The control board 27a, the insulating bracket 25a, the insulating cover plate 26a, the heat dissipation base plate 22a, and the heat dissipation cover plate 23a are all arranged in the chamber 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, such as screw connection. The insulating bracket 25a is arranged on the board surface of the circuit board 271a facing the box cover 212a.

[0231] In this way, when the electric control box 2a is disassembled for maintenance, the box cover 212a can be disassembled from the box body 21a, and then the insulating cover plate 26a can be disassembled from the insulating bracket 25a, and then the heat dissipation cover plate 23a and the heat dissipation bottom plate 22a are separated, and the cooling pipe 24a is removed from the heat dissipation cover plate 23a, and finally the box body 21a is disassembled from the housing 1, which is convenient for disassembly. At the same time, the electric control box 2a is arranged outside the housing 1, and is not affected by the temperature environment changes in the housing 1, and is more stable.

[0232] In an illustrative embodiment, Fig.18 As shown, the box body 211a of the electric control box 2a is arranged on the outer side wall of the first housing 11. The side wall of the box body 211a or the box cover 212a close to the chassis 13 is provided with a first notch 2121a. The first notch 2121a can be arranged on the side of the box cover 212a close to the box body 211a, and the opening of the first notch 2121a faces the box body 211a; the first notch 2121a can also be arranged on the side of the box body 211a close to the box cover 212a, and the opening of the first notch 2121a faces the box 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 both arranged on the side of the second heat exchanger 5 facing away from the electric control box 2a. The side of the second heat exchanger 5 facing away from the compressor 6 is close to the side wall of the second cavity 120.

[0233] like Fig.21 As shown, the kitchen air conditioner 100 further includes a first refrigerant pipe 91 and a second refrigerant pipe 92. The two ends of the first refrigerant pipe 91 are respectively connected to the second heat exchanger 5 and one end of the cooling pipe 24a. The two ends of the second refrigerant pipe 92 are respectively connected to the other end of the cooling pipe 24a and the throttling element or the second heat exchanger 5. Both the first refrigerant pipe 91 and the second refrigerant pipe 92 extend along the upper surface of the chassis 13. The first refrigerant pipe 91 extends from one end of the second heat exchanger 5 close to the compressor 6 to the second area 133 of the chassis 13, and then extends from the second area 133 to the bottom of the clearance groove 14, and extends along the bottom of the groove to the electric control box 2a, and finally extends to the bottom of the electric control box 2a and is 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 chassis 13, and then extends from the second area 133 to the bottom of the clearance groove 14, and extends along the bottom of the groove toward the electrical control box 2a, and finally extends to the bottom of the electrical control box 2a and is connected to the other end of the cooling pipe 24a.

[0234] Thus, when the electric control box 2a or the control board 27a is repaired or disassembled, the cooling pipe 24a is exposed after the box cover 212a, the heat dissipation cover plate 23a and the insulation cover plate 26a are removed. After the connection between the box body 211a and the housing 1 is released, the cooling pipe 24a only needs to be bent toward the outside of the housing 1 so that the cooling pipe 24a undergoes elastic deformation to expose the control board 27a or the box body 211a and the control board 27a are pulled out from the gap between the cooling pipe 24a and the housing 1, which is more convenient for repair or disassembly. Alternatively, after the box cover 212a is removed, the connection between the insulation bracket 25a and the control board 27a is released. The cooling pipe 24a with the insulation bracket 25a and other components only needs to be bent toward the outside of the housing 1 so that the cooling pipe 24a undergoes elastic deformation to expose the control board 27a or the box body 211a and the control board 27a are pulled out from the gap between the cooling pipe 24a and the housing 1, which is more convenient for repair or disassembly. At the same time, part of the first refrigerant tube 91 and part of the second refrigerant tube 92 are arranged along the bottom of the make way slot 14, making full use of the bottom space of the make way slot 14, reducing the space occupied by the first refrigerant tube 91 and the second refrigerant tube 92 in the first cavity 110 and the second cavity 120, making the kitchen air conditioner 100 more compact and more reasonably laid out. The first notch 2121a is provided on the side of the box body 21a close to the chassis 13, and both ends of the cooling tube 24a extend out of the box body 21a from the first notch 2121a, so as to facilitate connection with the first refrigerant tube 91 and the second refrigerant tube 92 extending along the chassis 13.

[0235] In an illustrative embodiment, Fig.18 , 21 As shown, the electric control box 2a is arranged on the outer side wall of the first housing 11 adjacent to the clearance groove 14, the first notch 2121a is arranged on the box cover 212a, the opening of the first notch 2121a communicates with the space between the box cover 212a and the box body 211a, the two ends of the cooling pipe 24a extend from the first notch 2121a of the box cover 212a and extend in a direction away from the box body 211a, and then bend and connect to the first refrigerant pipe 91 and the second refrigerant pipe 92 below the clearance groove 14. In this way, the cooling pipe 24a can allow greater deformation in the direction toward the outside of the housing 1, which is convenient for the maintenance and assembly and disassembly of the electric control box 2a or the control board 27a.

[0236] In an illustrative embodiment, Fig.21 As shown, one end of the second heat exchanger 5 is close to the compressor 6, and the 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 end of the second heat exchanger 5 close to the compressor 6, and the refrigerant pipes adjacent to the second heat exchanger 5 and the compressor 6 are connected to the end of the second heat exchanger 5 close to the compressor 6. The end of the second heat exchanger 5 facing away from the compressor 6 is close to the side wall of the second cavity 120.

[0237] In this way, the end of the second heat exchanger 5 close to the compressor 6 is used to connect the refrigerant pipe, 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, thereby making the kitchen air conditioner 100 more compact. At the same time, since the end of the second heat exchanger 5 close to the compressor 6 is used to connect the refrigerant pipe, the U-shaped heat exchange pipe 51 is arranged at the other end of the second heat exchanger 5, which can reduce the processing difficulty of the second heat exchanger 5.

[0238] In an illustrative embodiment, Fig.14 As shown, the kitchen air conditioner 100 further includes a protective cover 14. The protective cover 14 can be configured as a straight strip, and the protective cover 14 covers the bottom of the clearance groove 14. The protective cover 14 is connected to the housing 1, and the protective cover 14 and the housing 1 can be connected by a snap or screw. A pipe laying channel is formed between the protective cover 14 and the bottom of the clearance groove 14. 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 laying channel.

[0239] In this way, the protective cover 14 can separate the keel passing through the clearance slot 14 from the first refrigerant tube 91 and the second refrigerant tube 92 to prevent the keel from squeezing the first refrigerant tube 91 and the second refrigerant tube 92 and causing damage to the first refrigerant tube 91 and the second refrigerant tube 92 .

[0240] In an illustrative embodiment, Figure 8 , 23 As shown, the kitchen air conditioner 100 also includes a weak-current cable, a strong-current cable and a first wiring member 1a. One end of the strong-current cable and the weak-current cable are both connected to the control panel 27a of the electric control box, and the other ends of the strong-current cable and the weak-current cable are used to connect the electrical device controlled by the electric control box. The voltage transmitted by the weak-current cable is relatively low, for example, lower than 36V. The voltage transmitted by the strong-current cable is relatively high, for example, above 36V.

[0241] like Fig.23 As shown, the first wiring member 1a is made of insulating material, such as plastic, and has insulating properties. The first wiring member 1a is arranged in the first cavity 110 of the shell 1. One end of the first wiring member 1a is close to the electric control box 2a. The first wiring groove 11a and the second wiring groove 12a are arranged on the first wiring member 1a. The first wiring groove 11a and the second wiring groove 12a are arranged side by side. One end of the first wiring groove 11a and the second wiring groove 12a is close to the electric control box 2a. After the low-current cable extends out of the electric control box 2a, at least a part of the low-current cable is routed along the first wiring groove 11a. After the high-current cable extends out of the electric control box 2a, at least a part of the high-current cable is routed along the second wiring groove 12a.

The first wiring member 1a separates the weak-current cables from the strong-current cables to prevent electrical conduction between the strong-current cables and the weak-current cables. At the same time, when wiring the weak-current cables and the strong-current cables, they can be wired by plugging them into the first wiring groove 11a and the second wiring groove 12a respectively, which can improve assembly efficiency, and the weak-current cables and the strong-current cables can be quickly and safely removed from the first wiring member 1a during maintenance.

[0243] In an illustrative embodiment, the first wiring member 1a is configured as a strip. The first wiring member 1a may be configured as an L-shaped structure.

The first wiring groove 11a and the second wiring groove 12a both extend along the first wiring member 1a, extending from one end of the first wiring member 1a to the other end of the first wiring member 1a.

[0244] In this way, the first wiring member 1a is constructed in a strip shape, and the first wiring groove 11a and the second wiring groove 12a both extend along the first wiring member 1a. The structure of the first wiring member 1a is simpler, and the space occupied by the first wiring member 1a is small.

[0245] In an illustrative embodiment, a first wire clamping portion 13a is provided on the inner side wall of the first wiring groove 11a. The first wire clamping portion 13a can be constructed as a flat plate structure, and the first wire clamping portion 13a is parallel to the bottom of the first wiring groove 11a. The first wire clamping portion 13a extends from one inner side wall of the first wiring 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 distance between the first wire clamping portion 13a and the first wiring groove 11a, and the weak-current cable passes through the space between the first wire clamping portion 13a and the bottom of the first wiring groove 11a. Since the side of the bottom of the first wiring groove 11a facing away from the weak-current cable is held by the first wire clamping portion 13a, it is difficult for the weak-current cable to escape from the first wiring groove 11a.

[0246] In an exemplary embodiment, a plurality of first wire clamping portions 13a are provided on the first wiring member 1a, and the plurality of first wire clamping portions 13a are sequentially arranged along the first wiring groove 11a.

The second wire clamping portion 14a extends from one inner side wall of the second wiring groove 12a to the other inner side wall, and there is a gap between the second wire clamping portion 14a and the other inner side wall. There is a certain distance between the second wire clamping portion 14a and the second wiring groove 12a, and the high-voltage cable passes through the space between the second wire clamping portion 14a and the bottom of the second wiring groove 12a. Because the side of the bottom of the second wiring groove 12a facing away from the high-voltage cable is held by the second wire clamping portion 14a, it is difficult for the high-voltage cable to escape from the second wiring groove 12a.

[0249] In an exemplary embodiment, a plurality of second wire clamping parts 14a are provided on the first wiring member 1a, and the plurality of second wire clamping parts 14a are sequentially arranged along the second wiring groove 12a.
