Description

[0001] This application claims priority to Chinese patent application No. 202410490718.7, filed on April 23, 2024, entitled "Air Conditioner and its Control Box", the contents of which are to be understood as incorporated herein by reference. Technical Field

[0002] This article relates to air conditioner technology, and more particularly to an air conditioner and its control box. Background Technology

[0003] Because of their compact structure, small size, small installation space, and low installation difficulty, integrated air conditioners have become an irreplaceable category of air conditioners, filling the gaps in some scenarios where split-type air conditioners cannot be used.

[0004] Furthermore, due to the compact structure of integrated air conditioners, which use only one control board, there are many electrical components and high power, especially in high-power integrated air conditioners. Because their energy efficiency is lower than that of split air conditioners, integrated air conditioners have higher power consumption. In particular, in inverter refrigeration systems, there are many heat-generating electrical components, which requires improved heat dissipation performance of the control box.

[0024] In one illustrative embodiment, the insulating support is provided with a positioning hole, and the chip is provided with a positioning protrusion for insertion into the positioning hole.

[0025] This application also proposes an air conditioner that includes an electrical control box as described above.

[0026] In one illustrative embodiment, it also includes:

[0027] The housing has a first cavity and a second cavity inside. The first cavity is provided with a first air inlet and a first air outlet, and the second cavity is provided with a second air inlet and a second air outlet.

[0028] A first heat exchanger is disposed in the first cavity and is capable of exchanging heat with the air flowing through the first cavity;

[0029] A second heat exchanger is disposed within the second cavity and is capable of exchanging heat with the air flowing through the second cavity; and,

[0030] The compressor is connected to the first heat exchanger and the second heat exchanger respectively;

[0031] Throttling element;

[0032] The compressor, the second heat exchanger, the cooling pipe, the throttling element, and the first heat exchanger form a refrigeration circuit; or, the compressor, the second heat exchanger, the throttling element, and the first heat exchanger are connected in sequence to form a refrigeration circuit, and the cooling pipe leads the refrigerant out of the second heat exchanger, and the refrigerant flows back to the second heat exchanger after passing through the cooling pipe.

[0033] In one illustrative embodiment, the electrical control box is disposed outside the housing, and the box body is connected to the housing.

[0034] In one illustrative embodiment, the housing includes:

[0035] Chassis;

[0036] A first housing, covering the chassis and enclosing the first cavity with the chassis; and,

[0037] The second housing covers the chassis and encloses the second cavity with the chassis;

[0038] A clearance groove is formed between the first housing and the second housing for the keel to pass through, and the electrical control box is connected to the outer side wall of the first housing;

[0039] The compressor, the throttling element, and the second heat exchanger are all disposed within the second cavity;

[0040] The two ends of the cooling pipe extend from the side of the housing near the chassis;

[0041] The air conditioner also includes:

[0042] A first refrigerant pipe extends from the second heat exchanger along the chassis to one end of the cooling pipe; and

[0043] A second refrigerant pipe extends from the throttling element or the second heat exchanger along the chassis to the other end of the cooling pipe;

[0044] Among them, a portion of the first refrigerant pipe and a portion of the second refrigerant pipe are laid along the bottom of the relief channel.

[0045] In one illustrative embodiment, the electrical control box is disposed on the outer side wall of the first housing adjacent to the clearance slot; the box cover is provided with the first notch, and both ends of the cooling pipe extend out of the box body from the first notch, extend in a direction away from the box body, and bend to connect to the first refrigerant pipe and the second refrigerant pipe.

Part of the heat from the base plate is directly transferred to the cooling pipes, while another portion is transferred to the heat dissipation cover plate, which then transfers the heat to the cooling pipes. Because the refrigerant flowing through the cooling pipes carries away the heat dissipated by the control board, heat dissipation is rapid, ensuring that the temperature inside the control box does not become too high. This allows the electrical components on the control board to operate stably at a suitable temperature, improving the heat dissipation performance of the control box. Furthermore, this control box has a simple structure, is easy to assemble and disassemble, and is easily compatible with the structure of air conditioners.

[0078] like Figures 1-3 As shown, Figures 1-3 The structure of an air conditioner 100 in this embodiment is shown. The air conditioner 100 may be a kitchen air conditioner that is recessed and installed on the ceiling of a kitchen. The air conditioner 100 includes a first heat exchanger 3, a second heat exchanger 5, an electrical control box 2a, a throttling element, and a compressor 6.

[0079] like Figures 17-20 As shown, the electrical 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 has a box-shaped structure. The box body 21a may be made of insulating material, such as plastic. A chamber is provided inside the box body 21a. The control board 27a is the logic control unit of the air conditioner 100.

[0080] The control board 27a is located inside the cavity of the housing 21a. The control board 27a is the logic control unit of the air conditioner 100. Multiple electrical components are mounted on the control board 27a. Some of these components may be chips. These electrical components generate heat when operating.

[0081] The heat dissipation base plate 22a is made of a metallic material, such as aluminum or an 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 surface of the heat dissipation base plate 22a abuts against the control plate 27a.

[0082] The heat dissipation cover 23a is made of a metal material, such as aluminum or an aluminum alloy. The heat dissipation cover 23a has good thermal conductivity. The heat dissipation cover 23a covers the surface of the heat dissipation base plate 22a facing away from the control board 27a. The heat dissipation cover 23a and the heat dissipation base plate 22a enclose a cooling channel 20a. In this embodiment, as... Figure 20 As shown, the heat dissipation base plate 22a is recessed inwards towards the heat dissipation cover plate 23a to form a first groove 221a. The heat dissipation cover plate 23a is recessed inwards towards the heat dissipation base plate 22a to form a second groove 231a. The first groove 221a and the second groove 231a have the same shape and are aligned with each other. The inner walls of the first groove 221a and the second groove 231a enclose a cooling channel 20a.

[0083] Cooling pipe 24a may be made of metal. Cooling pipe 24a may be a copper pipe or an aluminum pipe. The shape of cooling pipe 24a is the same as that of cooling channel 20a. Cooling pipe 24a is disposed within cooling channel 20a and extends along cooling channel 20a. The outer diameter of cooling pipe 24a is equal to the diameter of cooling channel 20a, and the outer wall of cooling pipe 24a abuts against the inner wall of cooling channel 20a. Both ends of cooling pipe 24a extend between heat dissipation cover plate 23a and heat dissipation base plate 22a. The ends of cooling pipe 24a may be bent relative to cooling channel 20a to facilitate the connection of cooling pipe 24a to the refrigerant circulation system when the electrical control box 2a is vertically mounted on the air conditioner.

[0084] The throttling element can be an electronic expansion valve or a capillary tube. The throttling element can be located in the second cavity 120 and close to the compressor 6.

[0085] 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 via a refrigerant pipe 9. The outlet of the second heat exchanger 5 is connected to one end of the cooling pipe 24a via a refrigerant pipe 9. The other end of the cooling pipe 24a is connected to the throttling element via a refrigerant pipe 9. The throttling element is also connected to the inlet of the first heat exchanger 3 via a refrigerant pipe 9. The outlet of the first heat exchanger 3 is connected to the inlet of the compressor 6 via a refrigerant pipe 9.

[0086] In this way, when the air conditioner 100 is working, the control board 27a will generate heat and conduct the heat to the heat dissipation base plate 22a. Part of the heat on the heat dissipation base plate 22a is directly conducted 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. In cooling mode, the air conditioner 100 compresses the refrigerant with the compressor 6 and outputs the high-temperature, high-pressure refrigerant to the second heat exchanger 5. As the refrigerant flows through the second heat exchanger 5, it transfers heat to the air flowing over the outer surface of the second heat exchanger 5, cooling the refrigerant to a low-temperature state. The low-temperature refrigerant is then transported from the second heat exchanger 5 to the cooling pipe 24a. As the refrigerant flows through the cooling pipe 24a, it absorbs heat from the heat dissipation base plate 22a and the heat dissipation cover plate 23a, thereby carrying the heat emitted by the control board 27a out of the electrical control box 2a. After the refrigerant enters the throttling element, the throttling element reduces the pressure of the refrigerant. Then, the refrigerant is transported to the first heat exchanger 3 and absorbs heat from the air flowing over the outer surface of the first heat exchanger 3, evaporating. The refrigerant then flows back to the compressor 6 to complete one cycle.

[0087] In other illustrative embodiments, compressor 6, second heat exchanger 5, throttling element, and first heat exchanger 3 are sequentially connected to form a refrigeration circuit. Cooling pipe 24a introduces refrigerant into second heat exchanger 5 and the refrigerant flows back to second heat exchanger 5 after passing through cooling pipe 24a. The outlet of compressor 6 is connected to the inlet of second heat exchanger 5 via refrigerant pipe 9. The outlet of second heat exchanger 5 is connected to throttling element via refrigerant pipe 9. Throttling element is also connected to the inlet of first heat exchanger 3 via refrigerant pipe 9. The outlet of first heat exchanger 3 is connected to the inlet of compressor 6 via refrigerant pipe 9. Cooling pipe 24a can introduce refrigerant from the main flow or branch flow of second heat exchanger 5. After passing through cooling pipe 24a, the refrigerant flows back to second heat exchanger 5 before reaching the subcooling section, and then flows to the subcooling section.

[0088] In this way, when the air conditioner 100 is working, the control board 27a will generate heat and conduct the heat to the heat dissipation base plate 22a. Part of the heat on the heat dissipation base plate 22a is directly conducted 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. In cooling mode, the air conditioner 100 compresses the refrigerant using the compressor 6, and then outputs the high-temperature, high-pressure refrigerant to the second heat exchanger 5. As the refrigerant flows through the second heat exchanger 5, it transfers heat to the air flowing through the second cavity, cooling the refrigerant to a low temperature. The refrigerant is then transported from the second heat exchanger 5 to the cooling pipe 24a. As the refrigerant flows through the cooling pipe 24a, it absorbs heat from the heat dissipation base plate 22a and the heat dissipation cover plate 23a, thereby carrying away the heat emitted by the control board 27a from the electrical control box 2a. The refrigerant then re-enters the second heat exchanger 5 for cooling, ensuring that the cooling effect is not diminished. After passing through the second heat exchanger 5, the refrigerant enters the throttling element, which throttles and reduces the pressure of the refrigerant. The refrigerant is then transported to the first heat exchanger 3, where it absorbs heat from the air flowing through the first cavity and evaporates. The refrigerant then flows back to the compressor 6, completing one cycle.

[0089] Therefore, the refrigerant can carry away the heat dissipated by the control board 27a during the circulation process, resulting in rapid heat dissipation and ensuring that the temperature inside the control box 2a does not become too high, allowing the electrical components on the control board 27a to operate stably at a suitable temperature. At the same time, this control box 2a has a simple structure and is easy to assemble and disassemble.

[0090] In one illustrative embodiment, such as Figures 4-7 As shown, the air conditioner 100 also includes a housing 1, a first fan 2, and a second fan 4. A first cavity 110 and a second cavity 120 are provided within the housing 1. The first cavity 110 and the second cavity 120 are disposed 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. 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 disposed on the side wall of the first cavity 110. The first air inlet 101 communicates with the indoor space and is used to supply air into the first cavity 110. The first air outlet 102 is disposed 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.

[0091] A first fan 2 is connected to the housing 1. The first fan 2 is disposed within the first cavity 110. The first fan 2 is configured to drive air within the first cavity 110 to flow from the first air inlet 101 to the first air outlet 102 of the first cavity 110, thereby achieving air circulation 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. During operation, the first fan 2 draws air in through the first air inlet 211 and outputs it through 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 running, it can draw in air from the first cavity 110 and deliver the air from 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 draws in air from the first cavity 110, the air pressure in the first cavity 110 is negative, and the air outside the housing 1 enters the first cavity 110 from the first air inlet 101.

[0092] The first heat exchanger 3 is disposed within the first cavity 110. The first heat exchanger 3 may be disposed on the side of the first fan 2 near the first air inlet 101. When the air in the first cavity 110 flows from the first air inlet 101 to the first air outlet 102, it flows through the first heat exchanger 3, and the first heat exchanger 3 can exchange heat with this air.

[0093] The second fan 4 can be located at the second air outlet 104. The second fan 4 is configured to drive air within the second cavity 120 from the second air inlet 103 to the second air outlet 104 of the second cavity 120, thereby drawing indoor air into the second cavity 120 and then delivering it 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 running, it draws air in from the second air inlet 411 and outputs 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 running, it draws in air from the second cavity 120 and sequentially delivers the air from the second cavity 120 to the outside of the housing 1 through the second air outlet 413. After the second fan 4 draws in air from the second cavity 120, the air pressure inside the second cavity 120 becomes negative, and air from outside the housing 1 enters the second cavity 120 through 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 delivered laterally to the housing 1 through the second air outlet 413.

[0094] The second heat exchanger 5 is disposed within the second cavity 120. The second heat exchanger 5 may be disposed between the second air inlet 103 and the second air outlet 104. When the air in the second cavity 120 flows from the second air inlet 103 to the second air outlet 104, it flows through the second heat exchanger 5, and the second heat exchanger 5 can exchange heat with this air.

[0095] 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 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.

[0096] 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 mounted on the casing 1, making the air conditioner 100 a single, integrated unit. This simple structure allows for efficient production and rapid installation. Furthermore, with the casing 1 recessed into the ceiling, the first air inlet 101, the second air inlet 103, and the second air outlet 104 are all located above the ceiling. These features are concealed above the ceiling, enhancing aesthetics. The second fan 4 delivers air from the second cavity 120 to the side of the casing 1, facilitating the connection of the outdoor exhaust duct to the air conditioner 100 from the side of the casing 1 without requiring additional vertical installation space. The first air outlet 102 of the air conditioner 100 directs air downwards from the casing 1, quickly regulating the temperature of the space below the ceiling and improving the user experience.

[0097] In an illustrative 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 occupies more than 80% of the area of ​​the side wall of the first cavity 110 facing away from the second cavity 120. In this embodiment, as... Figure 1 , 2 As shown in Figure 8, other portions of the first air inlet 101 can be disposed on other sidewalls adjacent to the sidewall of the first cavity 110 facing away from the second cavity 120, thereby increasing the air intake area. At least a portion of the second air inlet 103 is disposed on the sidewall of the second cavity 120 facing away from the first cavity 110, and the area of ​​the second air inlet 103 disposed on the sidewall of the second cavity 120 facing away from the first cavity 110 accounts for more than 80% of the area of ​​the sidewall of the second cavity 120 facing away from the first cavity 110.

[0098] In this way, at least a portion of the first air inlet 101 and at least a portion of the second air inlet 103 are located on opposite sides of the housing 1, allowing air to enter from opposite sides of the housing 1, thus avoiding mutual interference between the air intakes of the first cavity 110 and the second cavity 120 and reducing noise. The first air inlet 101 and the second air inlet 103 can directly intake air from the outside of the housing 1, or they can be connected to air intake ducts. When one of the first air inlet 101 and the second air inlet 103 is connected to an air intake duct, the duct will not obstruct the other air intake, thereby affecting the air intake. Furthermore, the first air inlet 101 and the second air inlet 103 can be made larger, correspondingly increasing the air intake volume of the first cavity 110 and the second cavity 120. This allows for a reduction in the size of the housing 1 of the air conditioner 100 while maintaining the heat exchange efficiency of the first heat exchanger 3 and the second heat exchanger 5, resulting in a more compact structure for the air conditioner 100.

[0099] In one illustrative embodiment, such as Figure 1 , 2 As shown, the top of the housing 1 is recessed downwards to form a clearance groove 14. The clearance groove 14 can be configured 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 penetrates 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. The first cavity 110 and the 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.

[0100] 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.

[0101] The keel 1100 includes multiple first keels 1101, which are arranged in parallel and on the same horizontal plane, with adjacent first keels 1101 spaced apart. The spacing between adjacent first keels 1101 is the same. In other embodiments, the keel also includes multiple second keels 1102, which extend in a direction perpendicular to the first keels. Adjacent second keels 1102 are spaced apart. The spacing between adjacent second keels 1102 is the same. The multiple first keels and multiple second keels 1102 are constructed as a mesh structure, and each decorative panel covers one mesh opening in this mesh structure. The shape of the decorative panel 1200 is not limited and can be square or hexagonal, etc. As for the method of fixing the keel 1100 to the wall 2000, there are no restrictions here. In some schemes, the end of the keel 1100 is fixed to the wall. The kitchen ceiling is equipped with a hanging structure, and the keel 1100 is fixed to the hanging structure, so that the entire ceiling 1000 is suspended.

[0102] Under current technical solutions, when installing a pre-installed integrated kitchen air conditioner, the unit must be installed first, followed by the ceiling. Alternatively, part of the ceiling frame can be installed first, then the unit can be hoisted, with the remaining frame and decorative panels installed in between. When installing a pre-installed integrated kitchen air conditioner, due to its larger size, it is usually necessary to remove some decorative panels and the ceiling frame for installation. When the kitchen air conditioner needs cleaning or maintenance, at least some decorative panels must be removed. If disassembly for repair is required, the ceiling frame also needs to be removed. This makes cleaning and maintenance of the kitchen air conditioner very time-consuming, labor-intensive, and cumbersome.

[0103] The proposed solution addresses the aforementioned issues. Since the top of the housing 1 of the air conditioner 100 is provided with a clearance groove 14, which allows either the first joist 1101 or the second joist 1102 to pass through, during installation, the air conditioner 100 is simply installed by aligning the opening of the clearance groove 14 with the first joist 1101 below the ceiling. Then, the air conditioner 100 is raised to allow the first joist 1101 to enter the clearance groove 14 until it reaches the bottom. Finally, the air conditioner 100 is fixed, for example, by fixing it to the ceiling. This eliminates the need to disassemble the existing joists during installation. After installation, except for the bottom end of the housing 1, the rest of the housing 1 can be concealed within the space above the ceiling, resulting in a more aesthetically pleasing appearance. Correspondingly, when air conditioner 100 needs to be repaired, it is only necessary to loosen the fixing of air conditioner 100 and vertically lower the height of air conditioner 100 to remove it. During the removal of air conditioner 100, it is not necessary to disassemble the already installed keel. Compared with the existing technical solutions, the kitchen air conditioner of this embodiment reduces repair steps and time, and improves maintenance efficiency.

[0104] In one illustrative embodiment, such as 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.

[0105] The first housing 11 is disposed above the chassis 13. The electrical control box 2a is connected to the first housing 11. 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.

[0106] The second housing 12 is disposed above the chassis 13. The second housing 12 covers the second region 133 of the chassis 13. The second housing 12 and the second region 133 of the chassis 13 enclose a second cavity 120. The second air inlet 103 and the second air outlet 104 are both disposed on the side wall of the first housing 11.

[0107] The first housing 11 and the second housing 12 are spaced apart, so that the through groove 14 is located between the first housing 11 and the second housing 12 and above the connecting area 132.

[0108] In one illustrative embodiment, such as Figure 1 , 2 As shown in Figure 3, the first housing 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 vertically arranged. The partition 114 extends upward from the boundary between the first region 131 and the connecting region 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 on the bottom end of the partition 114 near the chassis 13, and the flange abuts against the chassis 13, and the flange is connected to the chassis 13 by screws.

[0109] like Figure 10As 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 region 131 of the chassis 13, away from the connecting region 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 set large enough. 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 one edge of the first region 131 to one end of the partition 114. The extending direction of the second side plate 1122 is approximately perpendicular to the surface of the partition 114. The second side plate 1122 may be provided with a side air inlet, serving as part of the first air inlet 101. Both the first side plate 1121 and the second side plate 1122 are screwed to the chassis 13. In this embodiment, the partition 114 may be provided with a flange on the side near the second side plate 1122, which abuts against the second side plate 1122, and the flange and the second side plate 1122 are connected by screws.

[0110] like Figure 14 As shown, the second plate 113 is constructed as a flat plate, which can be a rectangular flat plate. The electrical control box 2a is connected to the second plate 113. The second plate 113 has a first region 131 facing away from the edge of the second side plate 1122. The second plate 113 is vertically arranged. The second plate 113 extends from one end of the first side plate 1121 facing away from the second side plate 1122 along the edge of the first region 131 to one 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 assembly steps and enhance the connection strength between the second plate 113 and the chassis 13, allowing the second plate 113 to be more securely connected to the chassis 13.

[0111] like Figure 1As shown, a first top plate 111 is disposed above a first region 131 of the chassis 13 and is spaced apart from the chassis 13. The shape of the first top plate 111 is the same as the shape of the first region 131. The first top plate 111 is parallel to the chassis 13. The first top plate 111 is connected to the end of the partition 114, the first side plate 1121, the second side plate 1122, and 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 together. In this embodiment, a flange can be provided at the end of the partition 114 near the first top plate 111, and this flange is screwed to the first top plate 111.

[0112] In this way, the chassis 13, partition 114, first plate 112, second plate 113 and first top plate 111 enclose the first cavity 110. The first shell 11 is spliced ​​together by partition 114, first plate 112, second plate 113 and first top plate 111. The structure is simple, easy to process and manufacture, and has low cost.

[0113] In one illustrative embodiment, such as 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 chassis 13.

[0114] like Figure 8 As shown, the first fan 2 is disposed within 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.

[0115] The first heat exchanger 3 has a U-shaped structure, which has a large contact area with the air and high heat exchange efficiency. Since the first fan 2 is located in the internal cavity enclosed by the first heat exchanger 3 and the partition 114, the layout is compact, which can reduce the size of the first cavity 110 and make the overall volume of the air conditioner 100 smaller.

[0116] In one illustrative embodiment, such as Figure 9As shown, the first fan 2 includes a first air duct component 21, a first impeller 22, and a first motor 23. The first air duct component 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 pass through 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 connected to the internal cavity enclosed by the first heat exchanger 3 and the partition plate 114.

[0117] Two first impellers 22 are respectively disposed within the first air ducts 212 of the two first volutes 214. The first impellers 22 can be centrifugal impellers. The two first impellers 22 are coaxially arranged. A first motor 23 is disposed between the two first impellers 22, with both ends of the main shaft of the first motor 23 connected to the two first impellers 22 respectively. The first motor 23 can drive the two first impellers 22 to rotate synchronously. When the first impellers 22 rotate, they can drive the air in the first air duct 212 of the first volute 214 where they are 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 housing 215. The first air duct component 21, the two first impellers 22, and the first motor 23 form a module.

[0118] In this way, the two first impellers 22 of the first fan 2 rotate synchronously to deliver air, resulting in a larger air volume. At the same time, the first motor 23 is located between the two first impellers 22 and the two first volutes 214, making the structure of the first fan 2 more compact, requiring less installation space, and allowing the housing 1 to be made smaller.

[0119] Each first volute 214 can be provided with a first air inlet 211 on both sides to increase air volume. The U-shaped heat exchanger can be arranged around the first fan 2, and the two opposing first air inlets 211 of the two first volutes 214 face the two ends of the U-shaped heat exchanger respectively.

[0120] In one illustrative embodiment, such as Figure 9 As shown, a male buckle 216 is provided at the bottom of the first air duct component 21. Two male buckles 216 can be provided, with each buckle 216 located on one side of the two first volutes 214 near the chassis 13. (See diagram) Figure 14 As shown, the first area 131 of the chassis 13 is provided with female buckles 139. The number of female buckles 139 is the same as the number of male buckles 216. The female buckles 139 and male buckles 216 are set in a one-to-one correspondence. Each male buckle 216 can be inserted into its corresponding female buckle 139 to realize the snap-fit ​​connection between the first air duct component 21 and the chassis 13.

[0121] The first air duct component 21 is connected to the chassis 13 by a snap-fit ​​connection, which makes the assembly of the first fan 2 and the chassis 13 easier and increases the assembly speed.

[0122] In one illustrative embodiment, such as 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. A second air inlet 103 is disposed on the third side plate 1221. The third side plate 1221 extends upward from the edge of the second region 133 of the chassis 13 away from the edge of the connecting region 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 extends from one end of the third side plate 1221 along the edge of the second region 133 toward the connecting region 132.

[0123] like Figure 14 As shown, the fourth plate 123 is constructed as a vertically extending flat plate. The fourth plate 123 can be constructed as a rectangular plate. The fourth plate 123 is perpendicular to the chassis 13 and extends upwards from the edge of the second region 133 of the chassis 13, away from the edge of 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.

[0124] The second top plate 121 is disposed above the second region 133 of the chassis 13. The shape of the second top plate 121 may 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 to the end of the third side plate 1221, the fourth side plate 1222, and the fourth plate 123 facing away from the chassis 13.

[0125] like Figure 5 , 7 As shown, the second air outlet 104 of the second housing 12 is formed by the fourth side plate 1222, the fourth plate 123, the second top plate 121 and the second region 133 of the chassis 13 facing away from the third side plate 1221.

[0126] like Figure 12 , 13As shown, the second fan 4 includes a second air duct component 41, a second impeller 42, and a second motor 43. The second air duct component 41 is provided with a second air inlet 411, a second air outlet 413, and a second air duct 412. The second impeller 42 can be a centrifugal impeller. The second air duct 412 extends from the second air inlet 411 to the second air outlet 413. The second impeller 42 is disposed within the second air duct 412. The body of the second motor 43 is connected to the second air duct component 41. The main shaft of the second motor 43 is connected to the second impeller 42. The second motor 43 can drive the second impeller 42 to rotate, and when the second impeller 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 component 41 abuts against the end of the fourth side plate 1222, the fourth plate 123, and the second top plate 121 facing away from the third side plate 1221, and also abuts against the chassis 13. Thus, the second air duct component 41 can cover the second air outlet 104 of the second housing 12. The second air inlet 411 on the second air duct component 41 is configured to communicate with the second air outlet 104. The second air outlet 413 is configured to communicate 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 outdoors, so the second air outlet 413 can communicate with the outdoor space through the outdoor exhaust duct.

[0127] like Figure 5 As shown, the clearance channel 14 is formed by the second air duct component 41 of the second fan 4, the connection area 132 of the chassis 13 and the partition 114 of the first housing 11.

[0128] The second heat exchanger 5 is disposed within the second cavity 120 and sandwiched between the second air duct component 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 component 41 and the second air inlet 103 of the third side plate 1221. The second heat exchanger 5 can be a multi-row straight heat exchanger, with the second air inlet 411 facing the second heat exchanger 5.

[0129] In this way, the second air duct component 41 of the second fan 4 is disposed outside the second cavity 120 and serves as a wall of the second cavity 120. At the same time, the second air duct component 41 also serves as a side wall of the clearance groove 14, which can reduce the size of the air conditioner 100 in the width direction of the clearance groove 14, making the air conditioner 100 smaller.

[0130] In one illustrative embodiment, such as Figure 14 As shown, a clearance opening 1331 is provided in the second region 133 of the chassis 13. The clearance opening 1331 penetrates the chassis 13 vertically. The clearance opening 1331 can be constructed as a rectangular opening.

[0131] The second air duct component 41 of the second fan 4 extends into the relief opening 1331. The lower surface of the portion of the second air duct component 41 extending into the relief opening 1331 is flush with the lower surface of the chassis 13, or the portion of the second air duct component 41 extending into the relief opening 1331 can pass through the relief opening 1331 so that its lower surface protrudes slightly from the lower surface of the chassis 13.

[0132] In this way, the second air duct component 41 of the second fan 4 can partially extend into the relief 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 air conditioner 100 in the vertical direction.

[0133] In one illustrative embodiment, such as Figure 12 , 13 As shown, the second air duct component 41 includes a first plate 414, a second plate 415, and a second volute 416. The first plate 414 and the second plate 415 are flat. The first plate 414 extends from the boundary between the second region 133 and the connecting region 132 to the second top plate 121. The first plate 414 and the second plate 415 are parallel to each other and spaced apart. The second plate 415 is disposed on the side of the first plate 414 near the second heat exchanger 5. The second volute 416 is disposed between the first plate 414 and the second plate 415, with the first plate 414 and the second plate 415 respectively covering opposite ends of the second volute 416. A second air duct 412 is disposed within the second volute 416. A second air outlet 413 is disposed on the peripheral wall of the second volute 416. A second air inlet 411 is disposed on the second plate 415. The second impeller 42 is housed within the second volute 416, and the second motor 43 is housed within the second impeller 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 impeller 42. The lower end of the second volute 416 extends into the clearance opening 1331 of the chassis 13. This structure of the second fan 4 is more compact.

[0134] In one illustrative embodiment, such as Figure 14 , 15As shown, the upper surface of the chassis 13 of the casing 1 is also provided with a water collecting tank 134, a water pumping tank 136, and a water guiding tank 135. The water collecting tank 134 is located in the first region 131 of the chassis 13, below the first heat exchanger 3. The shape of the water collecting tank 134 can be the same as the shape of the projection of the first heat exchanger 3 onto the chassis 13, for example, both can be constructed as a U-shape. The water pumping tank 136 is located in the second region 133 of the chassis 13, below the second heat exchanger 5. The height of the bottom of the water collecting tank 134 can be greater than or equal to the height of the bottom of the water pumping tank 136. The water guiding tank 135 extends from the water collecting tank 134 to the water pumping tank 136. The water guiding tank 135 connects the water collecting tank 134 and the water pumping tank 136. The height of the bottom of the water guiding tank 135 may decrease in the direction extending from the water collecting tank 134 to the water pumping tank 136.

[0135] like Figure 14 , 16 As shown, the air conditioner 100 also includes a water pumping assembly 7. The water pumping assembly 7 is mounted on the chassis 13. The water pumping assembly 7 may be located in the second region 133. The water pumping assembly 7 includes a water pumping impeller 71 and a water pumping motor 72. The water pumping impeller 71 is generally disc-shaped. The water pumping impeller 71 is positioned above the chassis 13. The axis of the water pumping impeller 71 is horizontally aligned, and the water pumping impeller 71 extends at least partially into the water pumping trough 136. The water pumping motor 72 is drively connected to the water pumping impeller 71. The water pumping motor 72 can drive the water pumping impeller 71 to rotate.

[0136] When the air conditioner 100 is operating in cooling mode, the temperature of the first heat exchanger 3 is lower than the temperature of the air flowing through the first cavity 110. Water vapor in the air, due to pre-cooling, condenses onto the surface of the first heat exchanger 3, forming condensate droplets. These droplets, under pressure, drip into the water collection tank 134 and are collected. The condensate in the water collection tank 134 flows along the water inlet trough 135 into the water jetting trough 136. Since the water jetting wheel 71 extends into the water jetting trough 136, it comes into contact with the condensate. When the water jetting motor 72 drives the water jetting wheel 71 to rotate, it can throw the condensate in the water jetting trough 136 onto the second heat exchanger 5. When the air conditioner 100 is operating in cooling mode, the surface temperature of the second heat exchanger 5 is higher, allowing it to release heat to the condensate to evaporate it. As the condensate evaporates, it absorbs the heat released by the second heat exchanger 5, thereby improving the heat exchange efficiency of the second heat exchanger 5 and thus improving the energy efficiency of the air conditioner 100. At the same time, after the condensate is evaporated, the amount of condensate in the water tank 136 is reduced, and the condensate in the chassis 13 is prevented from overflowing. Therefore, there is no need to install a drain pipe to lead the condensate in the chassis 13 out of the air conditioner 100.

[0137] In one illustrative embodiment, such as Figure 14As shown, the air conditioner 100 also includes a water level switch 8. The water level switch 8 can be located inside the water inlet trough 136 or at one end of the water inlet trough 135 near the water inlet trough 136. The water level switch 8 can detect whether the water level in the water inlet trough 136 or the water inlet trough 135 has reached a preset threshold. The water level switch 8 is configured to shut off the compressor 6 after detecting that the water level in the water inlet trough 136 or the water inlet trough 135 has reached the preset threshold.

[0138] The preset threshold can be set slightly lower than the water level at the water level switch 8 when condensate overflows from any of the water inlet trough 136, water collection trough 134, or water inlet trough 135. If the water level in the water inlet trough 136 or water inlet trough 135 reaches the preset threshold, it indicates that there is a risk of condensate overflowing from the water inlet trough 136, water collection trough 134, or water inlet trough 135. At this time, the compressor 6 is turned off, which reduces the rate at which the first heat exchanger 3 produces condensate. At the same time, the water inlet impeller 71 is kept rotating to continuously consume the condensate that has already been produced, which can prevent condensate from overflowing when the air humidity is very high.

[0139] In one illustrative embodiment, such as Figure 14 As shown, a collection trough 137 is also provided on the chassis 13. The collection trough 137 is located below the second heat exchanger 5. The water-spraying trough 136 and the collection trough 137 are arranged sequentially in the direction of air flow 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 both the water-spraying trough 136 and the collection trough 137 can be perpendicular to the direction of air flow in the second cavity. The water-spraying trough 136 and the collection trough 137 are separated by a baffle. A through-hole 138 is provided on the baffle. The through-hole 138 can be a through hole or a notch through the baffle. The location of the through-hole 138 can be higher than the bottom of the water-spraying trough 136. The through-hole 138 can be located in the middle area of ​​the baffle in the vertical direction. The two ends of the through-hole 138 are connected to the collection trough 137 and the water-spraying trough 136, respectively.

[0140] In this way, after the water jet 71 throws out the condensate, some of the condensate droplets will be carried downstream by the airflow in the second cavity 120. At the same time, the condensate that has not been completely evaporated in the second heat exchanger 5 will also drip downwards. These condensate droplets will also be carried downstream by the airflow in the second cavity 120. Some of the condensate droplets that are deflected by the airflow will not fall back into the water jet 136, but will fall into the collection tank 137 and be collected. Then, they will flow back from the collection tank 137 into the water jet 136, preventing condensate from splashing onto other areas of the chassis 13 due to the wind force and causing condensate overflow.

[0141] In one illustrative embodiment, the body of the water-spraying motor 72 is located on the lower side of the second volute 416 and fixed to the chassis 13. In this embodiment, the second plate 415 is recessed into the first plate 414 to form a relief groove 4151, which is located on the lower side of the second volute 416, and the water-spraying body is disposed within the relief groove 4151.

[0142] By placing the body of the water pump 72 on the lower side of the second volute 416, the gap space between the volute and the chassis 13 can be fully utilized, making the structure of the air conditioner 100 more compact.

[0143] In one illustrative embodiment, the second heat exchanger 5 includes multiple heat exchange tube banks, with at least four such banks. These heat exchange tube banks are arranged sequentially along the airflow direction within the second cavity 120. The heat exchange channels of the multiple heat exchange tube banks are connected in series according to their arrangement direction.

[0144] In this way, the second heat exchanger 5 is equipped with more than four heat exchange tube rows for heat exchange, resulting in higher heat exchange efficiency and greater cooling capacity in cooling mode.

[0145] In one illustrative embodiment, such as Figure 8 As shown, compressor 6 is disposed within the second cavity 120 of housing 1. Compressor 6 is located at the end of the second fan 4 facing away from the second air outlet 413. Compressor 6 may be disposed at the end of the second fan 4 facing away from the fourth plate 123. Second heat exchanger 5 is disposed on the side of the second fan 4 facing away from the first cavity 110. Compressor 6 may be disposed at the end of the second heat exchanger 5 facing away from the fourth plate 123.

[0146] By placing the compressor 6 at one end of the second fan 4, the compressor 6 and its connected pipes can make full use of the space inside the second cavity 120, making the structure of the air conditioner 100 more compact and smaller in size.

[0147] In one illustrative embodiment, such as Figure 19 As shown, both the cooling pipe 24a and the cooling channel 20a are constructed in a U-shape.

[0148] The U-shaped cooling pipe 24a has a large contact area with the heat dissipation base plate 22a and heat dissipation cover plate 23a, resulting in faster heat conduction and better cooling effect. At the same time, the U-shaped cooling pipe 24a has a simple structure and is easy to manufacture.

[0149] In one illustrative embodiment, the control board 27a includes a circuit board 271a and a chip (not shown). The circuit board 271a is constructed as a flat plate. The circuit board 271a may be a printed circuit board. The chip is disposed on one surface of the circuit board 271a. The chip may be soldered onto the circuit board 271a. The circuit board 271a is fixed to the housing 21a. The connection between the circuit board 271a and the housing 21a may be screwed.

[0150] like Figure 20 As shown, the electrical 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 structure. A first through hole 214a is provided on the insulating bracket 25a. The first through hole 214a penetrates the insulating bracket 25a perpendicularly. One surface of the insulating bracket 25a abuts 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 extending direction of the first through hole 214a is perpendicular to the surface of the circuit board 271a.

[0151] A heat sink base plate 22a is disposed on the side of the insulating bracket 25a facing away from the circuit board 271a and is connected to the insulating bracket 25a. The heat sink base plate 22a may cover the surface of the insulating bracket 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 sink base plate 22a. The chip of the control board 27a passes through the first through hole 214a of the insulating bracket 25a, and the surface of the chip facing away from the circuit board 271a abuts against the heat sink base plate 22a.

[0152] In this way, the heat sink 22a is positioned on the side of the insulating bracket 25a facing away from the circuit board 271a. The insulating bracket 25a isolates the heat sink 22a from the circuit board 271a of the control board 27a, preventing the heat sink 22a from directly contacting the circuit board 271a and causing a short circuit on the circuit board 271a. Simultaneously, the chip is the main heat source on the control board 27a. The chip can pass through the first through-hole 214a and contact the heat sink 22a. The heat sink 22a can conduct the heat generated by the chip to the cooling pipe 24a, preventing the chip temperature from becoming too high.

[0153] In one illustrative embodiment, a positioning protrusion is provided on the side of the chip facing away from the circuit board 271a. This positioning protrusion can be truncated cone-shaped. A positioning hole 215a is provided on the insulating support 25a, which can be a circular hole. The positioning protrusion of the chip is inserted into the positioning hole 215a of the insulating support 25a.

[0154] The positioning protrusion of the chip cooperates with the positioning hole 215a of the insulating bracket 25a, making the alignment between the chip and the insulating bracket 25a more accurate.

[0155] In one illustrative embodiment, the electrical control box 2a further includes an insulating cover 26a. The insulating cover 26a is made of an insulating material, which may be an engineering plastic. The insulating cover 26a covers the side of the insulating bracket 25a facing away from the circuit board 271a, with a heat sink base plate 22a and a heat sink cover 23a sandwiched between the insulating cover 26a and the insulating bracket 25a. The insulating cover 26a and the insulating bracket 25a enclose a mounting cavity that accommodates the heat sink base plate 22a and the heat sink cover 23a. In this embodiment, the insulating bracket 25a is recessed towards the insulating cover plate 26a to form a first mounting groove 216a, the heat dissipation base plate 22a is disposed in the first mounting groove 216a, the insulating cover plate 26a is recessed towards the insulating bracket 25a to form a second mounting groove (not shown in the figure), the heat dissipation cover plate 23a is disposed 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 a mounting cavity for accommodating the heat dissipation base plate 22a and the heat dissipation cover plate 23a.

[0156] In this way, the insulating bracket 25a and the insulating cover plate 26a enclose an installation cavity. The heat dissipation base plate 22a, the heat dissipation cover plate 23a and the cooling pipe 24a are all set in the installation cavity. The insulating bracket 25a and the insulating cover plate 26a can provide heat insulation to lock the heat in the installation cavity, so that most of the heat can only be output from the cooling pipe 24a to the box 21a, preventing the temperature of other areas inside the box 21a from getting too high.

[0157] In one illustrative embodiment, the insulating cover plate 26a and the insulating support 25a are detachably connected. Alternatively, the insulating cover plate 26a and the insulating support 25a can be connected by a snap-fit ​​connection. Multiple hooks 261a are provided on the side wall of the insulating cover plate 26a, extending towards the insulating support 25a. Multiple protrusions 212a are provided on the side wall of the insulating support 25a, and the multiple hooks 261a respectively hook onto the multiple protrusions 212a, thereby achieving the snap-fit ​​connection between the insulating cover plate 26a and the insulating support 25a.

[0158] The heat sink base plate 22a and the heat sink cover plate 23a are detachably connected. The heat sink base plate 22a and the heat sink cover plate 23a can be connected by screws.

[0159] In this way, the heat dissipation base plate 22a is connected to the heat dissipation cover plate 23a, which clamps the cooling pipe 24a, minimizing the gaps between the heat dissipation base plate 22a and the cooling pipe 24a, as well as between the heat dissipation cover plate 23a and the cooling pipe 24a, thus improving heat transfer efficiency. Simultaneously, the insulating cover plate 26a is connected to the insulating bracket 25a, securing the heat dissipation base plate 22a, the cooling pipe 24a, and the heat dissipation cover plate 23a. Furthermore, since the heat dissipation base plate 22a and the heat dissipation cover plate 23a, as well as the insulating cover plate 26a and the insulating bracket 25a, can be disassembled first during maintenance, followed by the heat dissipation base plate 22a and the heat dissipation cover plate 23a, allowing the cooling pipe 24a to be separated from the other parts of the electrical control box, making disassembly more convenient.

[0160] In one illustrative embodiment, such as Figure 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 located outside the housing 1. The box body 211a can also be detachably connected to the outward-facing side of the second plate 113, i.e., the electrical control box 2a is located on the outer side wall of the first housing 11. Multiple hooks 217a can be provided at the bottom of the box body 211a, and multiple hanging holes 1131 are provided on the second plate 113. The hanging holes 1131 penetrate the second plate 113. The multiple hooks 217a hook onto the multiple hanging holes 1131 and hang on the second plate 113, so that the box body 211a can be hung on the second plate 113 by the hooks 217a. The second plate 113 and the box body 211a are also connected by screws. When it is necessary to separate the box body 211a from the second plate 113, simply unscrew the screws connecting the second plate 113 and the box body 211a, and then lift the box body 211a up so that the hook 217a disengages from the hanging hole 1131, and the box body 211a can be removed.

[0161] The lid 212a covers the body 211a and together they enclose a cavity. The lid 212a is located on the side of the body 211a facing away from the housing 1. The lid 212a is detachably connected to the body 211a. The body 211a and the lid 212a can be connected by screws.

[0162] The control board 27a, insulating bracket 25a, insulating cover plate 26a, heat dissipation base plate 22a, and heat dissipation cover plate 23a are all disposed within the cavity enclosed by the cover 212a and the body 211a. The circuit board 271a is connected to the side of the body 211a facing the cover 212a. The circuit board 271a and the body 211a can be detachably connected, for example, by screws. The insulating bracket 25a is disposed on the surface of the circuit board 271a facing the cover 212a.

[0163] In this way, when disassembling the electrical control box 2a for maintenance, the cover 212a can be removed from the box body 21a, the insulating cover 26a can be removed from the insulating bracket 25a, the heat dissipation cover 23a can be separated from the heat dissipation base plate 22a, the cooling pipe 24a can be removed from the heat dissipation cover 23a, and finally the box body 21a can be removed from the housing 1, making disassembly convenient. At the same time, since the electrical control box 2a is located outside the housing 1, it is not affected by the temperature changes inside the housing 1, making it more stable.

[0164] In one illustrative embodiment, such as Figure 18 As shown, the body 211a of the electrical control box 2a is located on the outer wall of the first housing 11. A first notch 2121a is provided on the side wall of the body 211a or the cover 212a near the chassis 13. The first notch 2121a can be located on the side of the cover 212a near the body 211a, with its opening facing the body 211a; alternatively, the first notch 2121a can be located on the side of the body 211a near the cover 212a, with its opening facing the cover 212a. Both ends of the cooling pipe 24a, after being bent relative to the cooling channel 20a, can extend out of the body 21a through the first notch 2121a. The compressor 6 and the throttling element are both located on the side of the second heat exchanger 5 facing away from the electrical control box 2a. The side of the second heat exchanger 5 facing away from the compressor 6 is located near the side wall of the second cavity 120.

[0165] like Figure 21 As shown, the air conditioner 100 also 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 one end of the second heat exchanger 5 and 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 the end of the second heat exchanger 5 near the compressor 6 to the second region 133 of the chassis 13, then extends from the second region 133 to the bottom of the clearance groove 14, and extends along the bottom of the groove towards the electrical control box 2a, finally extending to the bottom of the electrical control box 2a and connecting 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 region 133 of the chassis 13, then extends from the second region 133 to the bottom of the clearance channel 14, and extends along the bottom of the channel to the electrical control box 2a, and finally extends to the bottom of the electrical control box 2a and connects to the other end of the cooling pipe 24a.

[0166] Thus, when repairing or disassembling the electrical control box 2a or control board 27a, after removing the box cover 212a, heat dissipation cover 23a, and insulating cover 26a, the cooling pipe 24a is exposed. After disconnecting the box body 211a from the housing 1, simply bend the cooling pipe 24a outwards towards the housing 1 to cause elastic deformation, which will expose the control board 27a or pull the box body 211a and control board 27a out of the gap between the cooling pipe 24a and the housing 1, making repair and disassembly easier. Alternatively, after removing the box cover 212a, disconnect the insulating bracket 25a from the control board 27a. Simply bend the cooling pipe 24a, which includes the insulating bracket 25a and other components, outwards towards the housing 1 to cause elastic deformation, which will expose the control board 27a or pull the box body 211a and control board 27a out of the gap between the cooling pipe 24a and the housing 1, making repair and disassembly even easier. Meanwhile, some of the first refrigerant pipes 91 and some of the second refrigerant pipes 92 are laid along the bottom of the relief groove 14, making full use of the space at the bottom of the relief groove 14 and reducing the space occupied by the first refrigerant pipes 91 and 92 in the first cavity 110 and the second cavity 120, making the air conditioner 100 more compact and the layout more reasonable. The first notch 2121a is set on the side of the box 21a near the chassis 13, and both ends of the cooling pipe 24a extend out of the box 21a from the first notch 2121a, which facilitates connection with the first refrigerant pipes 91 and 92 extending along the chassis 13.

[0167] In one illustrative embodiment, such as Figure 18 , 21 As shown, the electrical control box 2a is disposed on the outer side wall of the first housing 11 adjacent to the clearance groove 14. A first notch 2121a is disposed on the cover 212a, the opening of which connects the space between the cover 212a and the body 211a. The two ends of the cooling pipe 24a extend from the first notch 2121a of the cover 212a and extend in a direction away from the 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 be allowed to deform more in the direction outward of the housing 1, which facilitates the maintenance and disassembly of the electrical control box 2a or the control board 27a.

[0168] In one illustrative embodiment, such as Figure 21 As shown, one end of the second heat exchanger 5 is close to the compressor 6, and this end is used to connect to the refrigerant pipe. Specifically, one end of the first refrigerant pipe 91 is connected to the end of the second heat exchanger 5 near the compressor 6, and adjacent refrigerant pipes of the second heat exchanger 5 and compressor 6 are connected to this end. The end of the second heat exchanger 5 facing away from the compressor 6 is close to the side wall of the first cavity 110.

[0169] In this way, the end of the second heat exchanger 5 closest to the compressor 6 is used to connect the refrigerant pipe, allowing the other end of the second heat exchanger 5 to be as close as possible to the side wall of the first cavity 110, thus making the air conditioner 100 more compact. At the same time, since the end of the second heat exchanger 5 closest to the compressor 6 is used to connect the refrigerant pipe, arranging all the U-shaped heat exchange tubes 51 at the other end of the second heat exchanger 5 reduces the manufacturing difficulty of the second heat exchanger 5.

[0170] In one illustrative embodiment, such as Figure 14 As shown, the air conditioner 100 also includes a protective cover 14. The protective cover 14 can be constructed as a straight strip, and the protective cover 14 covers the bottom of the recessed groove 14. The protective cover 14 is connected to the housing 1, and the connection between the protective cover and the housing 1 can be a snap-fit ​​connection or a screw connection. A pipe routing channel is formed between the protective cover 14 and the bottom of the recessed 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 routing channel.

[0171] In this way, the protective cover 14 can separate the keel passing through the relief groove 14 from the first refrigerant pipe 91 and the second refrigerant pipe 92, preventing the keel from squeezing the first refrigerant pipe 91 and the second refrigerant pipe 92 and causing damage to the first refrigerant pipe 91 and the second refrigerant pipe 92.

[0172] In one illustrative embodiment, such as Figure 8 , 23 As shown, the air conditioner 100 also includes low-voltage cables, high-voltage cables, and a first wiring component 1a. One end of both the high-voltage and low-voltage cables is connected to the control board 27a of the electrical control box, and the other end is used to connect to an electrical device controlled by the electrical control box. The low-voltage cables transmit a lower voltage, for example, below 36V. The high-voltage cables transmit a higher voltage, for example, above 36V.

[0173] like Figure 23 As shown, the first wiring component 1a is made of an insulating material, such as plastic, and has insulating properties. The first wiring component 1a is disposed within the first cavity 110 of the housing 1. One end of the first wiring component 1a is close to the electrical control box 2a. The first wiring component 1a is provided with a first wiring groove 11a and a second wiring groove 12a. 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 electrical control box 2a. After a low-voltage cable extends from the electrical control box 2a, at least a portion of the low-voltage cable is routed along the first wiring groove 11a. After a high-voltage cable extends from the electrical control box 2a, at least a portion of the high-voltage cable is routed along the second wiring groove 12a. Figure 8 , 17 As shown, the electrical control box 2a is provided with a low-voltage wire hole and a high-voltage wire hole. The low-voltage wire hole is connected to one end of the first wiring trough 11a, and the high-voltage wire hole is connected to one end of the second wiring trough 12a.

[0174] In this way, at least a portion of the low-voltage cable is arranged within the first wiring groove 11a of the first wiring component 1a. The first wiring component 1a separates this portion of the low-voltage cable from the portion of the high-voltage cable, preventing electrical conduction between the two. Simultaneously, wiring of the low-voltage and high-voltage cables can be completed simply by inserting them into the first wiring groove 11a and the second wiring groove 12a, respectively, improving assembly efficiency and allowing for quick and safe removal of the low-voltage and high-voltage cables from the first wiring component 1a during maintenance.

[0175] In one illustrative embodiment, the first wiring member 1a is constructed as a strip. The first wiring member 1a may also be constructed as an L-shape. The first wiring member 1a may extend along the top of the second plate 113 to the top of one end of the partition 114, and then extend from the top of one end of the partition 114 to the middle of the top of the partition 114. The first wiring groove 11a and the second wiring groove 12a both extend along the first wiring member 1a, from one end of the first wiring member 1a to the other end of the first wiring member 1a.

[0176] In this way, the first wiring component 1a is constructed as a strip, and the first wiring groove 11a and the second wiring groove 12a both extend along the first wiring component 1a. The structure of the first wiring component 1a is simpler, and the space occupied by the first wiring component 1a is smaller.

[0177] In an illustrative embodiment, a first wire-clamping portion 13a is provided on the inner wall of the first cable tray 11a. The first wire-clamping portion 13a can be constructed as a flat plate structure, parallel to the bottom of the first cable tray 11a. The first wire-clamping portion 13a extends from one inner wall of the first cable tray 11a to the other inner wall, with a gap between the first wire-clamping portion 13a and the other inner wall. A certain distance exists between the first wire-clamping portion 13a and the first cable tray 11a, and the low-voltage cable passes through the space between the first wire-clamping portion 13a and the bottom of the first cable tray 11a. Because the side of the low-voltage cable facing away from the bottom of the first cable tray 11a is held in place by the first wire-clamping portion 13a, it is difficult for the low-voltage cable to come out of the first cable tray 11a.

[0178] In one illustrative 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 arranged sequentially along the first wiring groove 11a. Three first wire-clamping portions 13a may be provided, with two first wire-clamping portions 13a respectively located at opposite ends of the first wiring groove 11a, and the remaining first wire-clamping portion 13a located in the middle of the first wiring groove 11a.

[0179] Multiple first cable clamps 13a can more securely fix the low-voltage cables within the first cable tray 11a.

[0180] In an illustrative embodiment, a second wire-clamping portion 14a is provided on the inner wall of the second cable tray 12a. The second wire-clamping portion 14a can be constructed as a flat plate structure, parallel to the bottom of the second cable tray 12a. The second wire-clamping portion 14a extends from one inner wall of the second cable tray 12a to the other inner wall, with a gap between the second wire-clamping portion 14a and the other inner wall. A certain distance exists between the second wire-clamping portion 14a and the second cable tray 12a, through which the high-voltage cable passes. Because the side of the high-voltage cable facing away from the bottom of the second cable tray 12a is held in place by the second wire-clamping portion 14a, it is difficult for the high-voltage cable to detach from the second cable tray 12a.

[0181] In one illustrative embodiment, a plurality of second wire-locking portions 14a are provided on the first wiring member 1a, and the plurality of second wire-locking portions 14a are arranged sequentially along the second wiring groove 12a. Three second wire-locking portions 14a may be provided, with two second wire-locking portions 14a respectively located at opposite ends of the second wiring groove 12a, and the remaining second wire-locking portion 14a located in the middle of the second wiring groove 12a.

[0182] Multiple second cable clamps 14a can more securely fix high-voltage cables within the second cable tray 12a.

[0183] In an illustrative embodiment, a first wiring component 1a is disposed within the first cavity 110 of the housing 1. The first wiring component 1a is positioned above the first heat exchanger 3. The top of the electrical control box 2a is provided with a low-voltage wire hole and a high-voltage wire hole. A first wiring groove 11a and a second wiring groove 12a are disposed on the side facing upwards from the first wiring component 1a. The openings of the first wiring groove 11a and the second wiring groove 12a face upwards. The top wall of the first cavity 110 of the housing 1 covers the openings of the first wiring groove 11a and the second wiring groove 12a. In this embodiment, the top wall of the first cavity 110 of the housing 1 is a first top plate 111.

[0184] In this way, since the first wiring component 1a is positioned above the first heat exchanger 3, the condensate generated by the first heat exchanger 3 is prevented from contacting the first wiring component 1a. Furthermore, since the openings of the first wiring trough 11a and the second wiring trough 12a face upwards, it is very convenient to arrange the low-voltage and high-voltage cables into the first wiring trough 11a and the second wiring trough 12a respectively before installing the first top plate 111, thus improving assembly efficiency. Simultaneously, after the wiring is completed, the first top plate 111 is installed in place, covering the openings of the first wiring trough 11a and the second wiring trough 12a, further preventing the low-voltage and high-voltage cables from escaping from the first wiring trough 11a and the second wiring trough 12a respectively.

[0185] In one illustrative embodiment, such as Figure 14 As shown, the air conditioner 100 also includes a second wiring component 3a. The second wiring component 3a is strip-shaped, and can be straight. The second wiring component 3a is disposed within the second cavity 120 of the housing 1. The second wiring component 3a can be vertically disposed on the chassis 13. The second wiring component 3a extends downward from the end of the first wiring component 1a facing away from the control box 2a to the chassis 13. The upward-facing top end of the second wiring component 3a is connected to the end of the first wiring component 1a facing away from the control box 2a, and the downward-facing bottom end of the second wiring component 3a is connected to the bottom wall of the first cavity 110, which is the chassis 13. The second wiring component 3a and the first wiring component 1a, as well as the second wiring component 3a and the chassis 13, can be connected by screws.

[0186] The second wiring component 3a is provided with a third wiring groove 31a and a fourth wiring groove 32a. The third wiring groove 31a extends from the top end of the second wiring component 3a to the bottom end of the second wiring component 3a, and vertically penetrates the second wiring component 3a. The fourth wiring groove 32a extends from the top end of the second wiring component 3a to the bottom end of the second wiring component 3a, and vertically penetrates the second wiring component 3a.

[0187] The top of the third wiring groove 31a of the second wiring component 3a is close to the end of the first wiring groove 11a of the first wiring component 1a facing away from the electrical control box 2a. At least a portion of the low-voltage cable is routed along the third wiring groove 31a.

[0188] The top of the fourth wiring groove 32a of the second wiring component 3a is close to the end of the second wiring groove 12a of the first wiring component 1a facing away from the electrical control box 2a, and at least a portion of the power cable is routed along the fourth wiring groove 32a.

[0189] In this way, the low-voltage cable extending from the end of the first wiring trough 11a of the first wiring component 1a facing away from the electrical control box 2a can enter the third wiring trough 31a of the second wiring component 3a, and extend downward along the third wiring trough 31a to the chassis 13, and then extend along the chassis 13 to various electrical devices, such as a water pump motor 72, a water level switch 8, etc. The high-voltage cable extending from the end of the second wiring trough 12a of the first wiring component 1a facing away from the electrical control box 2a can enter the fourth wiring trough 32a of the second wiring component 3a, and extend downward along the fourth wiring trough 32a to the chassis 13, and then extend along the chassis 13 to the electrical device, such as a first motor 23, a second motor 43, or a compressor 6.

[0190] In an illustrative embodiment, a third cable clamping portion 33a is provided on the inner wall of the third cable tray 31a. The third cable clamping portion 33a can be constructed as a flat plate structure, parallel to the bottom of the third cable tray 31a. The third cable clamping portion 33a extends from one inner wall of the third cable tray 31a to the other inner wall, with a gap between the third cable clamping portion 33a and the other inner wall. There is a certain distance between the third cable clamping portion 33a and the third cable tray 31a, and the low-voltage cable passes through the space between the third cable clamping portion 33a and the bottom of the third cable tray 31a. Because the side of the low-voltage cable facing away from the bottom of the third cable tray 31a is held in place by the third cable clamping portion 33a, it is difficult for the low-voltage cable to come out of the third cable tray 31a.

[0191] In one illustrative embodiment, the second wiring member 3a is provided with a plurality of third wire-locking portions 33a, which are arranged sequentially along the third wiring groove 31a. Three third wire-locking portions 33a may be provided, with two portions respectively located at opposite ends of the third wiring groove 31a, and the remaining portion located in the middle of the third wiring groove 31a.

[0192] Multiple third cable clamps 33a can more securely fix low-voltage cables within the third cable tray 31a.

[0193] In an illustrative embodiment, a fourth cable clamping portion 34a is provided on the inner wall of the fourth cable tray 32a. The fourth cable clamping portion 34a can be constructed as a flat plate structure, parallel to the bottom of the fourth cable tray 32a. The fourth cable clamping portion 34a extends from one inner wall of the fourth cable tray 32a to the other inner wall, with a gap between the fourth cable clamping portion 34a and the other inner wall. A certain distance exists between the fourth cable clamping portion 34a and the fourth cable tray 32a, through which the high-voltage cable passes. Because the side of the high-voltage cable facing away from the bottom of the fourth cable tray 32a is held in place by the fourth cable clamping portion 34a, it is difficult for the high-voltage cable to detach from the fourth cable tray 32a.

[0194] In one illustrative embodiment, the fourth wiring component is provided with a plurality of fourth wire-locking portions 34a, which are arranged sequentially along the fourth wiring groove 32a. Three fourth wire-locking portions 34a may be provided, with two fourth wire-locking portions 34a respectively located at opposite ends of the fourth wiring groove 32a, and the remaining fourth wire-locking portion 34a located in the middle of the fourth wiring groove 32a.

[0195] Multiple fourth cable clamps 34a can more securely fix high-voltage cables within the fourth cable tray 32a.

[0196] In one illustrative embodiment, the second wiring member 3a extends downward along the sidewall of the first cavity 110, which may be a partition 114. The openings of the third wiring groove 31a and the fourth wiring groove 32a face the sidewall of the first cavity 110, and the sidewall of the first cavity 110 covers the third wiring groove 31a and the fourth wiring groove 32a. In this embodiment, the second wiring member 3a extends downward from the middle of the top of the partition 114 to the middle of the bottom of the partition 114, and the partition 114 covers the openings of the third wiring groove 31a and the fourth wiring groove 32a.

[0197] In this way, since the openings of the third wiring trough 31a and the fourth wiring trough 32a face the partition 114, it is very convenient to arrange the low-voltage cables and high-voltage cables into the third wiring trough 31a and the fourth wiring trough 32a respectively before installing the partition 114, thus improving assembly efficiency. At the same time, after the wiring is completed, the partition 114 is installed in place, covering the openings of the third wiring trough 31a and the fourth wiring trough 32a, which can further prevent the low-voltage cables and high-voltage cables from coming out of the third wiring trough 31a and the fourth wiring trough 32a respectively.

[0198] In some embodiments, the power cables include a first power cable, a second power cable, and a third power cable. One end of the first power cable is connected to the first fan 2, and the other end is connected to the electrical control box. The electrical control box can supply power to the first fan 2 to drive its rotation via the first power cable. One end of the second power cable is connected to the second fan 4, and the other end is connected to the electrical control box. The electrical control box can supply power to the second fan 4 to drive its rotation via the second power cable. One end of the third power cable is connected to the compressor 6, and the other end is connected to the electrical control box. The electrical control box can supply power to the compressor 6 to drive its rotation via the third power cable.

[0199] In some embodiments, the air conditioner 100 further includes a temperature sensor for measuring indoor temperature and a display panel. The low-voltage cables include a first low-voltage cable, a second low-voltage cable, a third low-voltage cable, and a fourth low-voltage cable. One end of the first low-voltage cable is connected to the control box, and the other end is connected to the water pump motor 72. The control box can supply power to the water pump motor 72 to drive its rotation via the first low-voltage cable. One end of the second low-voltage cable is connected to the control box, and the other end is connected to the water level switch 8. The water level switch 8 transmits an electrical signal to the control box via the second low-voltage cable. One end of the third low-voltage cable is connected to the control box, and the other end is connected to the temperature sensor. The temperature sensor transmits an electrical signal to the control box via the third low-voltage cable. One end of the fourth low-voltage cable is connected to the control box, and the other end is connected to the display panel. The control box transmits an electrical signal to the display panel via the fourth low-voltage cable.
