Description

Technical Field

[0001] This article relates to refrigeration technology, and more particularly to an air conditioner. Background Art

[0002] The inverter module in the electric control box of the variable frequency air conditioner generates a lot of heat. In a high temperature environment, the inverter module cannot dissipate heat immediately, which will limit the high-frequency operation of the compressor. In the related art, the heat dissipation method of the inverter module is mostly to dissipate heat through air convection using a metal heat sink. However, in a high temperature outdoor environment, the heat dissipation effect of this heat dissipation method is poor. The heat generation of the inverter module can only be reduced by reducing the operating frequency of the compressor to ensure the normal operation of the air conditioner. This greatly affects the cooling effect of the variable frequency air conditioner when the outdoor ambient temperature is high, and thus affects the user's comfort.

[0003] At the same time, the heat exchange effects of heat exchange pipes at different positions of the condenser of the existing air conditioner are different. If the heat exchange pipes and the refrigerant are not properly matched, the condensation effect of the condenser will be reduced. Summary of the invention

[0078] like Figures 1 to 3 As shown, Figures 1 to 3 The structure of an air conditioner 100 in this embodiment is shown. The air conditioner 100 may be a kitchen air conditioner embedded in the ceiling of the kitchen. The air conditioner 100 includes an evaporator 3, a condenser 5, an electric control box 2a, a throttling element 10 and a compressor 6.

[0079] like Figures 17-20 As shown, the electric control box 2a includes a box body 21a, a control board 27a and a cooling pipe 24a. The box body 21a is constructed as a box-shaped structure. The box body 21a can be made of insulating material, such as plastic. A chamber is arranged in the box body 21a.

[0080] 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 air conditioner 100. A plurality of electrical components are arranged on the control board 27a, and some of the electrical components can form a frequency conversion module to adjust the operating frequency of the compressor. Some of the electrical components can be chips. These electrical components will generate heat when working.

[0081] The cooling tube 24a may be made of metal material. The cooling tube 24a may be a copper tube or an aluminum tube. The cooling tube 24a may be at least partially disposed in the chamber of the box body 21a, or in contact with the box body 21a, for heat dissipation of the control board 27a.

[0082] The throttling element 10 may be an electronic expansion valve or a capillary tube. The throttling element 10 may be arranged close to the compressor 6 .

[0083] like Fig.26As shown, the condenser 5 can be a fin heat exchanger. The condenser 5 includes a refrigerant inlet 55, a refrigerant outlet 56, a first heat exchange pipe 51 and a second heat exchange pipe 52. The first heat exchange pipe 51 and the second heat exchange pipe 52 can be metal pipes. The first heat exchange pipe 51 and the second heat exchange pipe 52 can both be copper pipes. The first heat exchange pipe 51 and the second heat exchange pipe 52 can respectively include a plurality of single pipes connected in sequence by U-shaped pipes. The first heat exchange pipe 51 and the second heat exchange pipe 52 of the condenser 5 can both allow the refrigerant to pass through. When the refrigerant passes through the first heat exchange pipe 51 and the second heat exchange pipe 52, heat is exchanged with the air, thereby releasing heat into the air, so that the temperature of the refrigerant is reduced. The first heat exchange pipe 51 and the cooling pipe 24a are connected in series to form a heat exchange pipeline, which is connected in parallel with the second heat exchange pipe 52. The refrigerant inlet 55 is used to receive the refrigerant input into the condenser 5, and the refrigerant outlet 56 is used to output the refrigerant in the condenser 5. One end of the first heat exchange pipe 51 may be connected to the refrigerant inlet 55 of the condenser 5, and the other end of the first heat exchange pipe 51 may be connected to the refrigerant outlet 56 of the condenser 5. The cooling pipe 24a is connected in series between the other end of the first heat exchange pipe 51 and the refrigerant outlet 56 or in series in the middle of the first heat exchange pipe 51, for example, in series downstream of the first heat exchange pipe 51 along the refrigerant flow direction, so as to better utilize the refrigerant cooled by the condenser 5 for electronically controlled heat dissipation. Both ends of the second heat exchange pipe 52 may be connected to the refrigerant inlet 55 and the refrigerant outlet 56, respectively. The refrigerant inlet 55 is used to receive the refrigerant input to the condenser 5, and the refrigerant outlet 56 is used to output the refrigerant to the condenser 5.

[0084] like Fig.25 As shown, the compressor 6, the condenser 5, the throttling element 10 and the evaporator 3 are connected in sequence to form a refrigeration circuit. The outlet of the compressor 6 is connected to the refrigerant inlet 55 of the condenser 5 through the refrigerant pipe 9. The refrigerant outlet 56 of the condenser 5 is connected to the throttling element 10 through the refrigerant pipe 9. The throttling element 10 is also connected to the inlet of the evaporator 3 through the refrigerant pipe 9. The outlet of the evaporator 3 is connected to the inlet of the compressor 6 through the refrigerant pipe 9.

[0085] In this way, the control board 27a of the air conditioner 100 will generate heat when it is working, and this heat can be transferred to the cooling pipe 24a. In the cooling mode of the air conditioner 100, the compressor 6 compresses the refrigerant, and then outputs the high-temperature and high-pressure refrigerant to the refrigerant inlet 55 of the condenser 5. When the refrigerant flows through the first heat exchange pipe 51 and the second heat exchange pipe 52 of the condenser 5, it transfers heat to the air flowing through the outer surface of the first heat exchange pipe 51 and the second heat exchange pipe 52, and the refrigerant is cooled to a low-temperature refrigerant. Then the refrigerant enters the condenser 5, and part of the refrigerant flows through the first heat exchange pipe 51 and is transported to the cooling pipe 24a. These refrigerants absorb the heat emitted by the control board 27a when flowing through the cooling pipe 24a to cool the electrical components on the control board 27a. The other part of the refrigerant is transported through the second heat exchange pipe 52. After the refrigerant flows out of the cooling pipe 24a, it merges with the refrigerant in the second heat exchange pipe 52 and is output from the condenser 5 from the refrigerant outlet 56 of the condenser 5. After the refrigerant output from the condenser 5 enters the throttling element 10, the throttling element 10 throttles and reduces the pressure of the refrigerant. Then, the refrigerant is transported to the evaporator 3, absorbs the heat of the air flowing through the outer surface of the evaporator 3 and evaporates. The refrigerant flows back to the compressor 6 to complete a cycle.

[0086] Therefore, the refrigerant flowing through the cooling pipe 24a can take away the heat emitted by the control board 27a. The control board 27a dissipates heat quickly, 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. Compared with air cooling, the refrigerant flowing through the cooling pipe 24a has a better cooling effect on the control board 27a, and the heat dissipation effect is not affected by the high temperature outdoor environment. It can be used in scenes with harsh climate and high heat generation, such as scenes with high outdoor ambient temperature and high operating frequency of the compressor 6. The first heat exchange pipe 51 and the second heat exchange pipe 52 are connected in parallel, and the refrigerant transported by the first heat exchange pipe 51 will be affected by the heat of the control board 27a, and the temperature of the refrigerant transported by the second heat exchange pipe 52 is relatively stable. The two are mixed, so that the temperature of the refrigerant at the refrigerant outlet 56 of the condenser 5 is more stable, and the condensation effect of the condenser 5 is better.

[0087] In the related art, a plurality of parallel heat exchange pipes may be provided on the condenser. Due to some objective reasons, it is difficult for the plurality of heat exchange pipes to achieve the same heat exchange effect, resulting in different temperatures of the refrigerants output by the plurality of heat exchange pipes. The temperature of the refrigerants output by the heat exchange pipes with better heat exchange effect is lower, and the temperature of the refrigerants output by the heat exchange pipes with poor heat exchange effect is higher. If the temperature difference of the refrigerants output by the plurality of heat exchange channels is large, the condensation effect of the condenser will also be reduced, the cooling capacity will be reduced, and the compressor power will be increased.

[0088] In an illustrative embodiment, the heat exchange efficiency of the second heat exchange pipe 52 is lower than that of the first heat exchange pipe 51. Since the heat exchange efficiency of the first heat exchange pipe 51 is higher than that of the second heat exchange pipe 52, the temperature of the refrigerant originally flowing out of the first heat exchange pipe 51 is lower than that of the refrigerant flowing out of the second heat exchange pipe 52. The temperature of the refrigerant flowing out of the first heat exchange pipe 51 will increase after passing through the cooling pipe 24a, so that the temperature of the refrigerant output by the cooling pipe 24a is closer to that of the refrigerant output by the second heat exchange pipe, so that the temperature difference between the refrigerant output by the cooling pipe 24a and the refrigerant output by the second heat exchanger is reduced when they merge, thereby improving the condensing efficiency of the condenser 5 and the cooling capacity of the air conditioner, and reducing the power of the compressor.

[0089] In an illustrative embodiment, the condenser 5 further includes a collecting pipe 53 and a third heat exchange pipe 54. The collecting pipe 53 and the third heat exchange pipe 54 are both metal pipes. The collecting pipe 53 can be a flute pipe. The collecting pipe 53 is provided with a first inlet 531, a second inlet 532 and a first outlet 533.

[0090] One end of the first heat exchange pipe 51 is connected to the refrigerant inlet 55 of the condenser 5, and the other end of the first heat exchange pipe 51 is connected to the cooling pipe 24a. The end of the cooling pipe 24a away from the first heat exchange pipe 51 is connected to the first inlet 531 of the collecting pipe 53. One end of the second heat exchange pipe 52 is connected to the refrigerant inlet 55 of the condenser 5, and one end of the second heat exchange pipe 52 is connected to the second inlet 532 of the collecting pipe 53. The first outlet 533 of the collecting pipe 53 is connected to one end of the third heat exchange pipe 54. The other end of the third heat exchange pipe 54 is connected to the refrigerant outlet 56 of the condenser 5.

[0091] In this way, the refrigerant output by the cooling pipe 24a and the second heat exchange pipe 52 is respectively transported to the collecting pipe 53 through the first inlet 531 and the second inlet 532 of the collecting pipe 53, and the refrigerant output by the cooling pipe 24a and the second heat exchange pipe 52 is transported to the third heat exchange pipe 54 after merging in the collecting pipe 53. When the refrigerant flows through the third heat exchange pipe 54, it exchanges heat with the air, which can further reduce the temperature of the whole refrigerant, thereby releasing the heat absorbed by the refrigerant when flowing through the cooling pipe 24a into the air, thereby improving the cooling effect. The refrigerant in the third heat exchange pipe 54 is output through the refrigerant outlet 56 of the condenser 5. The third heat exchange pipe 54 can be the supercooling section of the condenser 5.

[0092] In the related art, one of the objective reasons leading to significantly different heat exchange effects among multiple heat exchange pipes of the condenser is that the air conditioner is provided with a water wheel. When the water wheel rotates, water is splashed onto multiple heat exchange pipes to cool the heat exchange pipes. However, the water wheel has a limited range of water spraying, and the amount of water splashed on each heat exchange pipe is different, resulting in different heat exchange effects among the multiple heat exchange pipes.

[0093] In an illustrative embodiment, Fig.14 , 15 As shown, the upper surface of the chassis 13 of the housing 1 is also provided with a water collecting trough 134, a first water drawing trough 136 and a water inlet trough 135. The water collecting trough 134 is arranged in the first area 131 of the chassis 13 and is located below the evaporator 3. The shape of the water collecting trough 134 can be the same as the shape of the projection of the evaporator 3 on the chassis 13, for example, both are constructed in a U shape. The first water drawing trough 136 is arranged in the second area 133 of the chassis 13 and is located below the condenser 5. The height of the bottom of the water collecting trough 134 can be greater than or equal to the height of the bottom of the first water drawing trough 136. The water inlet trough 135 extends from the water collecting trough 134 to the first water drawing trough 136. The water inlet trough 135 connects the water collecting trough 134 and the first water drawing trough 136. The height of the bottom of the water drawing trough 135 can have a tendency to decrease in the direction extending from the water collecting trough 134 to the first water drawing trough 136.

[0094] like Fig.14 , 16 As shown, the 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 first water pumping wheel 71 and a water pumping motor 72. The first water pumping wheel 71 is constructed in a roughly disc shape. The first water pumping wheel 71 is arranged above the chassis 13. The axis of the first water pumping wheel 71 is arranged horizontally, and the first water pumping wheel 71 at least partially extends into the first water pumping groove 136. The water pumping motor 72 is transmission-connected to the first water pumping wheel 71. The water pumping motor 72 can drive the first water pumping wheel 71 to rotate.

[0095] When the air conditioner 100 is operated in the cooling mode, the temperature of the evaporator 3 is lower than the temperature of the air flowing through the first cavity 110. The water vapor in the air is pre-cooled and condensed on the surface of the evaporator 3 to form condensed water droplets. The condensed water droplets on the surface of the evaporator 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 first water pumping tank 136 along the water guide tank 135. Since the first water pumping wheel 71 extends into the first water pumping tank 136, it can contact the condensed water in the first water pumping tank 136. When the water pumping motor 72 drives the first water pumping wheel 71 to rotate, the condensed water in the first water pumping tank 136 can be thrown onto the condenser 5. When the air conditioner 100 is operated in the cooling mode, the surface temperature of the condenser 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 condenser 5, thereby improving the heat exchange efficiency of the condenser 5, and further improving the energy efficiency of the air conditioner 100. At the same time, after the condensed water is evaporated, the amount of condensed water in the first 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 air conditioner 100.

[0096] In an illustrative embodiment, the water pumping assembly 7 is configured so that the flow rate of the condensed water thrown onto the first heat exchange pipe 51 is greater than the flow rate of the condensed water thrown onto the second heat exchange pipe 52 .

[0097] In this way, since the flow rate of condensed water transported to the first heat exchange pipe 51 is greater than the flow rate of condensed water transported to the second heat exchange pipe 52, the heat carried away by the condensed water in the first heat exchange pipe 51 is greater than the heat carried away by the condensed water in the second heat exchange pipe 52, thereby ensuring that the heat exchange efficiency of the first heat exchange pipe 51 is higher than that of the second heat exchange pipe 52.

[0098] In an illustrative embodiment, Fig.14 As shown, the air conditioner 100 further includes a water level switch 8. The water level switch 8 can be disposed in the first water tank 136, or can be disposed at one end of the water diversion tank 135 close to the first water tank 136. The water level switch 8 can detect whether the water level in the first water tank 136 or the water diversion 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 first water tank 136 or the water diversion tank 135 reaches a preset threshold.

[0099] 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 first water tank 136, the water collecting tank 134 and the water diversion tank 135. When the water level in the first water tank 136 or the water diversion tank 135 reaches the preset threshold value, it means that the condensed water is at risk of overflowing the first water tank 136, the water collecting tank 134 or the water diversion tank 135. At this time, the compressor 6 is turned off, so that the rate at which the evaporator 3 produces condensed water decreases, and at the same time, the first water 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.

[0100] In an illustrative embodiment, Fig.14 , 27As shown, a second water trough 137 is also provided on the chassis 13. The second water trough 137 is located below the condenser 5. The first water trough 136 and the second water trough 137 are arranged in sequence in the flow direction of the air in the second cavity, that is, in the flow direction of the air flowing through the condenser 5, for example, in the direction from the second air inlet 103 to the second air outlet 104. The extension direction of the first water trough 136 and the extension direction of the second water trough 137 can both be perpendicular to the flow direction of the air in the second cavity 120. The first water trough 136 and the second water trough 137 are separated by a baffle 138. A through hole 1380 is provided on the baffle 138. The through hole 1380 can be set as a through hole that passes through the baffle 138, or it can be set as a notch that passes through the baffle 138. The position of the through hole 1380 can be higher than the bottom of the first water trough 136. The through hole 1380 may be disposed in the middle region of the baffle plate 138 in the vertical direction. Both ends of the through hole 1380 are connected to the second water trough 137 and the first water trough 136 respectively.

[0101] like Fig. 27 As shown, the water pumping assembly 7 further includes a second water pumping wheel 70. The first water pumping wheel 71 and the second water pumping wheel 70 are both sleeved on the main shaft of the water pumping motor 72, and the water pumping motor 72 can drive the first water pumping wheel 71 and the second water pumping wheel 70 to rotate synchronously.

[0102] In this way, after the first 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 by the condenser 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 first water trough 136, but fall into the second water trough 137 to be collected, and then flow back from the second water trough 137 to the first water trough 136, which can 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.

[0103] At the same time, when the water pumping motor 72 drives the second water pumping wheel 70 to rotate, the condensed water in the second water pumping tank 137 can be thrown onto the condenser 5. When the air conditioner 100 is running in the cooling mode, the surface temperature of the condenser 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 condenser 5, thereby improving the heat exchange efficiency of the condenser 5, and further improving the energy efficiency of the air conditioner 100. At the same time, after the condensed water is evaporated, the amount of condensed water in the second water pumping tank 137 can be reduced to prevent the condensed water from overflowing.

[0104] In an illustrative embodiment, the condenser 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 first water wheel 71 and the second water wheel 70 are arranged between different adjacent heat exchange tube rows. The first heat exchange pipe 51 and the second heat exchange pipe 52 can be arranged along the heat exchange tube rows arranged in sequence.

[0105] In this way, the condenser 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.

[0106] In an illustrative embodiment, the total heat exchange area of ​​the first heat exchange pipe 51 is greater than the total heat exchange area of ​​the second heat exchange pipe 52. For example, when the first heat exchange pipe 51 and the second heat exchange pipe 52 use heat exchange pipes with the same diameter, the total length of the first heat exchange pipe 51 is greater than the total length of the second heat exchange pipe 52, so that the heat exchange efficiency of the first heat exchange pipe 51 is higher than the heat exchange efficiency of the second heat exchange pipe 52.

[0107] In an illustrative embodiment, the first heat exchange pipe 51 and the second heat exchange pipe 52 can be immersed in the condensed water of the first water tank 136 and / or the second water tank 137 respectively, and the area of ​​the first heat exchange pipe 51 located in the condensed water is larger than the area of ​​the second heat exchange pipe 52 located in the condensed water, so that the heat exchange efficiency of the first heat exchange pipe 51 is higher than the heat exchange efficiency of the second heat exchange pipe 52.

[0108] In an illustrative embodiment, Figures 4 to 7As 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 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 disposed 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.

[0109] 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.

[0110] The evaporator 3 is disposed in the first cavity 110. The evaporator 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 evaporator 3 when flowing from the first air inlet 101 to the first air outlet 102, and the evaporator 3 can exchange heat with the air.

[0111] 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.

[0112] The condenser 5 is disposed in the second cavity 120. The condenser 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 condenser 5 when flowing from the second air inlet 103 to the second air outlet 104, and the condenser 5 can exchange heat with the air.

[0113] 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 evaporator 3 and the condenser 5 through the refrigerant pipe 9. The refrigerant pipe 9, the evaporator 3 and the condenser 5 may be pre-filled with refrigerant. The compressor 6 can drive the refrigerant to circulate between the evaporator 3 and the condenser 5, so that heat is transferred between the evaporator 3 and the condenser 5 with the refrigerant as the carrier. In the cooling mode of the air conditioner 100, the evaporator 3 acts as an evaporator, and the condenser 5 acts as a condenser 5. When the refrigerant flows through the evaporator 3, it evaporates and absorbs the heat of the air flowing through the first cavity. When the refrigerant flows through the condenser 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.

[0114] In this way, the first fan 2, the second fan 4, the evaporator 3, the condenser 5 and the compressor 6 are all installed on the housing 1, and the air conditioner 100 is constructed as an integrated machine, and the structure of this air conditioner 100 is simple, and efficient production and quick installation can be achieved. At the same time, after the housing 1 of this 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 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 air conditioner 100 from the side of the housing 1, and will not increase the installation space required for the air conditioner 100 in the vertical direction. The first air outlet 102 of the 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.

[0115] 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.

[0116] In this way, at least part of the first air inlet 1011 and at least part of the second air inlet 1031 are respectively located on opposite sides of the housing 1, and air is taken in from opposite sides of the housing 1, respectively, so as to avoid mutual influence between the air inlet of the first cavity 110 and the second cavity 120, and reduce 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 inlet duct. When one of the first air inlet 101 and the second air inlet 103 is connected with the air inlet duct, the air inlet 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, and the size of the housing 1 of the air conditioner 100 can be reduced while ensuring the heat exchange efficiency of the evaporator 3 and the condenser 5, so that the structure of the air conditioner 100 is more compact.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] According to the existing technical solution, when the integrated kitchen air conditioner is installed from the 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 kitchen air conditioner needs to be cleaned or maintained, at least part of the spliced ​​decorative panels need to be removed. When the integrated kitchen air conditioner is installed from the back, 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. 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.

[0121] The present application solution can solve the above problem. Since the top of the housing 1 of the 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 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 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 air conditioner 100 is fixed, for example, by fixing the air conditioner 100 through the ceiling to complete the installation. During the installation of the air conditioner 100, it is not necessary to remove the installed keel. After the air conditioner 100 is installed, except for the end of the bottom end of the housing 1, the rest of the housing 1 can be hidden in the interlayer space above the ceiling, which is more beautiful. Accordingly, when the air conditioner 100 needs to be repaired, it is only necessary to release the fixation of the air conditioner 100 and vertically lower the height of the air conditioner 100 to disassemble the air conditioner 100, and it is not necessary to disassemble the installed keel during the disassembly process of the air conditioner 100. Compared with the prior art solutions, the kitchen air conditioner of the embodiment of the present invention reduces the repair steps and time, and improves the maintenance efficiency.

[0122] 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.

[0123] The first housing 11 is disposed above the chassis 13. The electric control box 2a is connected to the first housing 11. 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 the side wall of the first housing 11.

[0124] The second housing 12 is disposed above the chassis 13. The second housing 12 covers the second area 133 of the chassis 13. The second housing 12 and the second area 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.

[0125] 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 .

[0126] 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.

[0127] 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.

[0128] like Fig.14As shown, the second plate 113 is constructed as a flat plate, which can be a rectangular flat plate. The electric control box 2a is connected to the second plate 113. The second plate 113 is provided with an 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 one end of the first side plate 1121 facing away from the second side plate 1122 along the edge of the first area 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 the assembly steps and enhance the connection strength between the second plate 113 and the chassis 13, and the second plate 113 can be more firmly connected to the chassis 13.

[0129] 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.

[0130] 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.

[0131] In an illustrative embodiment, Figure 8 As shown, the evaporator 3 is constructed as a U-shaped heat exchanger. The evaporator 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 evaporator 3 are respectively close to the two ends of the partition 114. The evaporator 3 and the partition 114 enclose an internal cavity. The bottom end of the evaporator 3 is connected to the bottom plate 13.

[0132] like Figure 8 As shown, the first fan 2 is disposed in the internal cavity enclosed by the evaporator 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 bottom plate 13.

[0133] The evaporator 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 evaporator 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 air conditioner 100 is smaller.

[0134] 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 evaporator 3 and the partition 114.

[0135] 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.

[0136] 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.

[0137] 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.

[0138] 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 connection between the first air duct member 21 and the chassis 13.

[0139] 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.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] 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 .

[0144] 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 wind wheel 42 can be a centrifugal wind wheel. 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 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 fuselage 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.

[0145] 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 .

[0146] The condenser 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 condenser 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.

[0147] 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 air conditioner 100 in the width direction of the make way slot 14, making the volume of the air conditioner 100 smaller.

[0148] 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.

[0149] 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.

[0150] 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 air conditioner 100 in the vertical direction.

[0151] 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 condenser 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.

[0152] 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.

[0153] 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 air conditioner 100 more compact.

[0154] 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 condenser 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.

[0155] 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 structure of the air conditioner 100 more compact and smaller in size.

[0156] In an illustrative embodiment, Fig.19 As shown, the electric control box 2a further includes a heat dissipation base plate 22a and a heat dissipation cover plate 23a.

[0157] 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.

[0158] 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.

[0159] The shape of the cooling pipe 24a is the same as that of the cooling channel 20a. The cooling pipe 24a is arranged in the cooling channel 20a and extends along the cooling channel 20a. The outer diameter of the cooling pipe 24a is equal to the diameter of the cooling channel 20a, and the outer wall of the cooling pipe 24a abuts against the inner wall of the cooling channel 20a. Both ends of the cooling pipe 24a extend from between the heat dissipation cover plate 23a and the heat dissipation bottom 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 when the electric control box 2a is vertically arranged on the air conditioner.

[0160] When the control board 27a generates heat, it transfers 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 tube 24a, and the other 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 tube 24a, thereby increasing the heat dissipation area of ​​the control board 27a and improving the heat dissipation effect.

[0161] In an illustrative embodiment, Fig.19 As shown, both the cooling tube 24a and the cooling channel 20a are configured in a U shape.

[0162] 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.

[0163] 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.

[0164] like Fig. 20 As 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.

[0165] 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.

[0166] 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.

[0167] 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 is inserted into the positioning hole 215a of the insulating bracket 25a.

[0168] 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.

[0169] 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.

[0170] 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.

[0171] 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.

[0172] 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.

[0173] 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.

[0174] 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 are respectively hooked on the plurality of hanging holes 1131 and 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.

[0175] 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.

[0176] 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.

[0177] 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.

[0178] 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 10 are both arranged on the side of the condenser 5 facing away from the electric control box 2a. The side of the condenser 5 facing away from the compressor 6 is close to the side wall of the second cavity 120.

[0179] like Fig.21As shown, the 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 one end of the first heat exchange pipe 51 of the condenser 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 first inlet 531 of the collecting pipe 53. The first refrigerant pipe 91 and the second refrigerant pipe 92 both extend along the upper surface of the chassis 13. The first refrigerant pipe 91 extends from one end of the condenser 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 condenser 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.

[0180] 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 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.

[0181] In an illustrative embodiment, Fig.18 , 21As 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.

[0182] In an illustrative embodiment, Fig.21 As shown, one end of the condenser 5 is close to the compressor 6, and the end of the condenser 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 condenser 5 close to the compressor 6, and the refrigerant pipes adjacent to the condenser 5 and the compressor 6 are connected to the end of the condenser 5 close to the compressor 6. The end of the condenser 5 facing away from the compressor 6 is close to the side wall of the first cavity 110.

[0183] In this way, the end of the condenser 5 close to the compressor 6 is used to connect the refrigerant pipe, so that the other end of the condenser 5 can be as close to the side wall of the first cavity 110 as possible, thereby making the air conditioner 100 more compact. At the same time, since the end of the condenser 5 close to the compressor 6 is used to connect the refrigerant pipe, the U-shaped heat exchange tube 51 is arranged at the other end of the condenser 5, which can reduce the difficulty of processing the condenser 5.

[0184] In an illustrative embodiment, Fig.14 As shown, the 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.

[0185] 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 .

[0186] In an illustrative embodiment, Figure 8 , 23As shown, the 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.

[0187] 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. As shown Figure 8 , 17 As shown, the electric control box 2a is provided with a weak-wire hole and a strong-wire hole. The weak-wire hole is connected to one end of the first wiring trough 11a, and the strong-wire hole is connected to one end of the second wiring trough 12a.

[0188] In this way, at least a portion of the weak-current cables are arranged in the first wiring groove 11a of the first wiring member 1a, and at least a portion of the weak-current cables are arranged in the first wiring groove 11a of the first wiring member 1a. 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.

[0189] 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 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, extending from one end of the first wiring member 1a to the other end of the first wiring member 1a.

[0190] 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.

[0191] 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.

[0192] 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. Three first wire clamping portions 13a may be provided, two first wire clamping portions 13a are respectively provided at opposite ends of the first wiring groove 11a, and the remaining first wire clamping portion 13a is provided in the middle of the first wiring groove 11a.

[0193] The plurality of first cable clamping portions 13a can more stably fix the weak-current cables in the first wiring groove 11a.

[0194] In an illustrative embodiment, a second wire clamping portion 14a is provided on the inner side wall of the second wiring groove 12a. The second wire clamping portion 14a can be constructed as a flat plate structure, and the second wire clamping portion 14a is parallel to the bottom of the second wiring groove 12a. 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.

[0195] 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.

[0196] The plurality of second cable clamping portions 14a can more stably fix the high-voltage cables in the second cable routing groove 12a.

[0197] In an illustrative embodiment, the first wiring member 1a is disposed in the first cavity 110 of the shell 1. A hole for weak-wires and a hole for strong-wires are provided at the top of the electric control box 2a. The first wiring member 1a is disposed above the evaporator 3. The first wiring groove 11a and the second wiring groove 12a are disposed on the upward side of the first wiring member 1a. The opening of the first wiring groove 11a and the opening of the second wiring groove 12a face upward. The top wall of the first cavity 110 of the shell 1 covers the opening of the first wiring groove 11a and the opening of the second wiring groove 12a. In this embodiment, the top wall of the first cavity 110 of the shell 1 is a first top plate 111.

[0198] In this way, since the first wiring member 1a is arranged above the evaporator 3, the condensed water generated by the first heat exchanger 3 is prevented from contacting the first wiring member 1a, and the openings of the first wiring groove 11a and the second wiring groove 12a are facing upward, it is very convenient to arrange the weak-current cables and the strong-current cables in the first wiring groove 11a and the second wiring groove 12a respectively before installing the first top plate 111, thereby improving the assembly efficiency. At the same time, after the wiring is completed, the first top plate 111 is installed in place, and the first top plate 111 covers the openings of the first wiring groove 11a and the second wiring groove 12a, which can further prevent the weak-current cables and the strong-current cables from escaping from the first wiring groove 11a and the second wiring groove 12a respectively.

The third clamping portion 33a extends from an inner side wall of the third wiring groove 31a to the other inner side wall, and there is a gap between the third clamping portion 33a and the other inner side wall. There is a certain spacing between the third clamping portion 33a and the third wiring groove 31a, and the weak-current cable passes through the space between the third clamping portion 33a and the groove bottom of the third wiring groove 31a. Because the side of the groove bottom of the weak-current cable facing away from the third wiring groove 31a is held by the third clamping portion 33a, it is difficult for the weak-current cable to escape from the third wiring groove 31a.

[0205] In an exemplary embodiment, a plurality of third wire clamping portions 33a are provided on the second wiring member 3a, and the plurality of third wire clamping portions 33a are sequentially arranged along the third wiring groove 31a.

There is a certain spacing between the fourth clamping portion 34a and the fourth wiring groove 32a, and the strong current cable passes through the space between the fourth clamping portion 34a and the bottom of the groove of the fourth wiring groove 32a. Because the side of the bottom of the groove of the strong current cable facing away from the fourth wiring groove 32a is held by the fourth clamping portion 34a, it is difficult for the strong current cable to escape from the fourth wiring groove 32a.

[0208] In an exemplary embodiment, the fourth wiring member is provided with a plurality of fourth wire clamping portions 34a, and the plurality of fourth wire clamping portions 34a are sequentially arranged along the fourth wiring groove 32a.

[0211] In this way, since the openings of the third wiring trough 31a and the fourth wiring trough 32a are toward the side of the partition 114, it is very convenient to arrange the weak-current cables and the strong-current cables in the third wiring trough 31a and the fourth wiring trough 32a respectively before installing the partition 114, thereby improving the assembly efficiency. At the same time, after the wiring is completed, the partition 114 is installed in place, and the partition 114 covers the openings of the third wiring trough 31a and the fourth wiring trough 32a, which can further prevent the weak-current cables and the strong-current cables from escaping from the third wiring trough 31a and the fourth wiring trough 32a respectively.
