Description

Technical Field

[0001] The present invention relates to air conditioner technology, and more particularly to an air conditioner and its electric control box. Background Art

[0002] Since integrated air conditioners have a compact structure, small size, small installation space and low installation difficulty, integrated air conditioners, as an irreplaceable air conditioner category, make up for some scenarios where split air conditioners cannot be used.

[0003] In addition, since the integrated air conditioner has a compact structure and only uses one electronic control board, which has many electrical components and high power, especially in higher-power integrated air conditioners, because their energy efficiency is lower than that of split air conditioners, the integrated air conditioner has higher electrical power, especially in variable-frequency refrigeration systems, where there are many heat-generating parts in the electrical components, and the heat dissipation performance of the electronic control box needs to be improved.

The air inlet of the air outlet interface of the exhaust fan, the first heat dissipation outlet of the box body, the first heat dissipation cavity of the box body and the first heat dissipation inlet of the box body are connected in sequence. When the air outlet interface of the air conditioner exhausts air outward, the flow rate of the air flow flowing through the air outlet interface is high, and a negative pressure is formed at the air inlet of the air outlet interface. Since the air pressure at the first heat dissipation inlet of the box body is the ambient atmospheric pressure, which is higher than the air pressure at the air inlet of the air outlet interface, the air at the first heat dissipation inlet of the box body flows through the first heat dissipation inlet, the first heat dissipation cavity, the first heat dissipation outlet and the air inlet of the box body in sequence under the action of atmospheric pressure and enters the air outlet interface. When the air flows through the radiator in the first heat dissipation cavity, the heat dissipated by the radiator can be taken away, thereby realizing forced air cooling of the control board. The airflow takes away the heat dissipated by the control board, and the control board dissipates heat quickly, ensuring that the temperature in the electric control box will not be too high, and the electrical components on the control board can work stably at a suitable temperature. Thereby, the heat dissipation performance of the electric control box is improved.

[0058] like Figure 1 , 2 As shown, Figure 1 , 2 The structure of an air conditioner 100 in an embodiment of the present application is shown. The air conditioner 100 includes an exhaust fan 4 and an electric control box 7. An air outlet pipe interface 421 is provided on the exhaust fan 4. The air outlet pipe interface 421 is connected to the outdoor space and is used to transport air to the outdoor space. Figure 6 As shown, an air inlet 4211 is provided on the side wall of the air outlet pipe interface 421 .

[0059] like Figures 3 to 5 As shown, the electric control box 7 includes a box body 71, a radiator 73 and a control board 72. The box body 71 is constructed as a box-shaped structure for protecting the components inside it. The box body 71 is provided with a first heat dissipation cavity 701, a first heat dissipation inlet 703 and a first heat dissipation outlet 704. The first heat dissipation cavity 701 is constructed as a cavity. The first heat dissipation inlet 703 and the first heat dissipation outlet 704 are both connected to the first heat dissipation cavity 701. The first heat dissipation outlet 704 is connected to the air inlet 4211 of the air outlet duct interface 421 through a pipeline.

[0060] The heat sink 73 is disposed in the first heat sink cavity 701. The heat sink 73 may be a fin heat sink. The heat sink 73 may be made of metal, such as aluminum or an aluminum alloy. The heat conductivity of the heat sink 73 is very good.

[0061] A portion of the control board 72 is disposed in the first heat dissipation cavity 701 of the box body 71. The control board 72 is a logic control unit of the air conditioner 100. The control board 72 is provided with a plurality of electrical components, and the plurality of electrical components constitute a control circuit for controlling the operation of the air conditioner 100. The electrical components on the control board 72 may be inductors, capacitors, and chips. These electrical components generate a large amount of heat when powered on. The control board 72 abuts against the radiator 73, and some electrical components on the control board 72 may abut against the radiator 73. At least a portion of the heat generated by the control board 72 may be diffused into the air of the first heat dissipation cavity 701 through the radiator 73.

[0062] In this way, when the air conditioner 100 is working, the control panel 72 will generate heat and transfer the heat to the radiator 73, and the radiator 73 will dissipate the heat into the surrounding air. The air inlet 4211 of the air outlet pipe interface 421 of the exhaust fan 4, the first heat dissipation outlet 704 of the box body 71, the first heat dissipation cavity 701 of the box body 71 and the first heat dissipation inlet 703 of the box body 71 are connected in sequence. When the exhaust fan 4 exhausts air outward through the air outlet pipe interface 421, the flow rate of the air flow flowing through the air outlet pipe interface 421 is relatively high, and a negative pressure is formed at the air inlet 4211 of the air outlet pipe interface 421. Since the air pressure at the first heat dissipation inlet 703 of the box body 71 is the ambient atmosphere, the air pressure at the air outlet 4211 is relatively high. The pressure is higher than the pressure of the air inlet 4211 of the air outlet interface 421. The air at the first heat dissipation inlet 703 of the box body 71 flows through the first heat dissipation inlet 703, the first heat dissipation cavity 701, the first heat dissipation outlet 704, and the air inlet 4211 of the box body 71 under the action of atmospheric pressure and enters the air outlet interface 421. When the air flows through the radiator 73 in the first heat dissipation cavity 701, the heat emitted by the radiator 73 can be taken away, thereby realizing forced air cooling of the control board 72. The airflow takes away the heat emitted by the control board 72, and the control board 72 dissipates heat quickly, ensuring that the temperature in the electric control box 7 will not be too high, and the electrical components on the control board 72 can work stably at a suitable temperature.

[0063] In an illustrative embodiment, Figure 4 As shown, the first heat dissipation cavity 701 is configured as a strip-shaped cavity, which may be a straight strip-shaped cavity. The cross section of the first heat dissipation cavity 701 may be rectangular. The first heat dissipation inlet 703 is configured at one end of the first heat dissipation cavity 701 and the first heat dissipation outlet 704 is configured at the other end of the first heat dissipation cavity 701. After the airflow enters one end of the first heat dissipation cavity 701 from the first heat dissipation inlet 703, it flows along the extension direction of the first heat dissipation cavity 701, and then exits the first heat dissipation cavity 701 from the first heat dissipation outlet 704.

[0064] like Figure 5 As shown, the radiator 73 includes a substrate 731 and a plurality of fins 732. The substrate 731 can be configured as a flat plate. The substrate 731 can be a rectangular flat plate. One surface of the substrate 731 faces the control board 72 and abuts against the control board 72. The plurality of fins 732 are all arranged on the surface of the substrate 731 facing away from the control board 72. The plurality of fins 732 are all perpendicular to the substrate 731. The surfaces of the plurality of fins 732 are parallel to each other and are all parallel to the extension direction of the first heat dissipation cavity 701, that is, parallel to the direction from the first heat dissipation inlet 703 to the first heat dissipation outlet 704. Two adjacent fins 732 are spaced apart. The spacing between two adjacent fins 732 can be the same. The fins 732 can be configured as a straight strip-shaped flat plate structure, and the length direction of the fins 732 is parallel to the extension direction of the first heat dissipation cavity 701.

[0065] In this way, the heat on the control board 72 is transferred to the base plate 731, and then conducted from the base plate 731 to the plurality of fins 732, and then the fins 732 conduct the heat to the air. Since the contact area between the plurality of fins 732 and the air is large, the heat exchange efficiency of the radiator 73 can be increased. At the same time, since the plate surface of the fin 732 is parallel to the extension direction of the first heat dissipation cavity 701, and the airflow flows in the first heat dissipation cavity 701 along the extension direction of the first heat dissipation cavity 701, the plate surface of the fin 732 is parallel to the flow direction of the airflow, and the resistance imposed by the fin 732 on the airflow is small, and the flow rate of the air flowing through the first heat dissipation cavity 701 can be correspondingly increased, thereby improving the heat dissipation effect of the electric control box 7.

[0066] In an illustrative embodiment, Figure 4 As shown, the box body 71 is also provided with a second heat dissipation cavity 702, a heat dissipation channel 700, a second heat dissipation inlet 705 and a second heat dissipation outlet 706. The second heat dissipation cavity 702 is a cavity. The first heat dissipation cavity 701 and the second heat dissipation cavity 702 are separated. The heat dissipation channel 700 is arranged adjacent to the second heat dissipation cavity 702, that is, the second heat dissipation channel 700 and the heat dissipation channel 700 are separated by only a common wall. The heat dissipation channel 700 is constructed as a strip channel, and the shape of the heat dissipation channel 700 is not limited, and can be a straight strip channel or a curved channel, such as an S-shaped channel. The second heat dissipation inlet 705 is arranged at one end of the heat dissipation channel 700, and the second heat dissipation outlet 706 is arranged at the other end of the heat dissipation channel 700. The two ends of the heat dissipation channel 700 are respectively connected to the second heat dissipation inlet 705 and the second heat dissipation outlet 706. The second heat dissipation outlet 706 is connected to the air intake 4211 on the pipe wall of the air outlet pipe interface 421.

[0067] The control board 72 includes a first electrical component (not shown in the figure), a second electrical component 722 and a circuit board 721. The circuit board 721 may be a printed circuit board 721. A portion of the circuit board 721 is located in the first heat dissipation cavity 701, and another portion of the circuit board 721 is located in the second heat dissipation cavity 702. The first electrical component may be a chip. The first electrical component is arranged in the first heat dissipation cavity 701 and connected to the portion of the circuit board 721 located in the first heat dissipation cavity 701, and the first electrical component is offset against the substrate 731 of the radiator 73. The volume of the second electrical component 722 is greater than that of the first electrical component. The second electrical component 722 may be an inductor or a capacitor. The second electrical component 722 is arranged in the second heat dissipation cavity 702 and connected to the portion of the circuit board 721 located in the second heat dissipation cavity 702. There is a gap between the second electrical component 722 and the inner wall of the second heat dissipation cavity 702 of the box body 71, and the second electrical component 722 does not contact the inner wall of the second heat dissipation cavity 702.

[0068] In this way, the heat emitted by the first electrical component on the circuit board 721 is dissipated into the air flowing through the first heat dissipation cavity 701 through the radiator 73. The heat emitted by the second electrical component 722 on the circuit board 721 can be transmitted to the wall surface of the heat dissipation channel 700 in the form of thermal radiation. The air intake port 4211 of the air outlet pipe interface 421 of the exhaust fan 4, the second heat dissipation outlet 706 of the box body 71, the heat dissipation channel 700 of the box body 71 and the second heat dissipation inlet 705 of the box body 71 are connected in sequence. When the exhaust fan 4 exhausts air outward through the air outlet pipe interface 421, the flow rate of the air flow flowing through the air outlet pipe interface 421 is relatively high, and a negative pressure is formed at the air intake port 4211 of the air outlet pipe interface 421. In addition, the air pressure at the second heat dissipation inlet 705 of the box body 71 is the ambient atmospheric pressure. , which is higher than the air pressure of the air inlet 4211 of the air outlet interface 421, the air at the second heat dissipation inlet 705 of the box body 71 flows through the second heat dissipation inlet 705, the heat dissipation channel 700, the second heat dissipation outlet 706, the air inlet 4211 of the box body 71 in sequence under the action of atmospheric pressure and enters the air outlet interface 421. When the air flows through the heat dissipation channel 700, it can take away the heat radiated by the second electrical component 722, thereby cooling the second electrical component 722 of the control board 72. Since the air does not directly enter the second heat dissipation cavity 702 to cool the second electrical component 722, the air tightness of the second heat dissipation cavity 702 can be ensured, and pollutants in the air can be prevented from entering the second heat dissipation cavity 702 and polluting the second electrical component 722. For example, when the air conditioner 100 is used as a kitchen air conditioner 100, the oil smoke in the kitchen cannot enter the second heat dissipation cavity 702 and pollute the second electrical component 722.

[0069] In an illustrative embodiment, the wall surface shared by the first heat dissipation cavity 701 and the heat dissipation channel 700 is provided with a first protrusion 707 at a position corresponding to at least part of the second electrical component 722. The first protrusion 707 protrudes toward the side where the heat dissipation channel 700 is located, thereby increasing the heat dissipation area, playing a spoiler role, and enhancing the heat exchange effect. The top of at least part of the second electrical component 722 can be accommodated inside the first protrusion 707, thereby reducing the thickness of the electric control box 7. The outer side surface of the heat dissipation channel 700 can be provided with a second protrusion 708 at a position corresponding to the first protrusion 707. The second protrusion 708 protrudes in a direction away from the first heat dissipation cavity 701, thereby maintaining a larger air duct cross-sectional area between the first protrusion 707 and the second protrusion 708, thereby avoiding a reduction in air volume and ensuring a heat dissipation effect.

[0070] In an illustrative embodiment, the electric control box 7 further includes an insulating bracket 74. The insulating bracket 74 is made of an insulating material. The insulating bracket 74 can be constructed as a rectangular plate-like structure. A clearance through hole 741 is provided on the insulating bracket 74. The clearance through hole 741 vertically penetrates the insulating bracket 74. A plate surface of the insulating bracket 74 abuts against a plate surface of the circuit board 721. The insulating bracket 74 is connected to the circuit board 721. The insulating bracket 74 and the circuit board 721 can be connected by screws. The depth direction of the clearance through hole 741 is perpendicular to the plate surface of the circuit board 721.

[0071] The heat sink 73 is disposed on a side of the insulating bracket 74 facing away from the circuit board 721, and is connected to the insulating bracket 74. The substrate 731 of the heat sink 73 may be covered on the board surface of the insulating bracket 74 facing away from the circuit board 721. One end of the clearance through hole 741 faces the circuit board 721, and the other end of the clearance through hole 741 faces the substrate 731 of the heat sink 73. The first electrical component of the control board 72 passes through the clearance through hole 741 of the insulating bracket 74, and the surface of the first electrical component facing away from the circuit board 721 abuts against the substrate 731 of the heat sink 73.

[0072] In this way, the insulating bracket 74 isolates the radiator 73 from the circuit board 721 of the control board 72, preventing the radiator 73 from directly contacting the circuit board 721 and causing a short circuit on the circuit board 721. At the same time, the first electrical component can pass through the clearance hole 741 to contact the radiator 73, directly conduct heat to the radiator 73, and significantly improve the heat dissipation effect of the first electrical component. At the same time, through the cooperation of the insulating bracket 74 and the circuit board 721, and the cooperation of the substrate of the radiator 73 and the insulating bracket 74, the first electrical component is located in the clearance hole 741, and the first electrical component is also shielded, reducing the contamination of the first electrical component.

[0073] In an illustrative embodiment, Figure 3As shown, the box body 71 includes a box body 711, a box cover 712 and a cover plate 713. The box body 711 can be constructed in a roughly square disk shape. The box cover 712 covers the box body 711 and encloses an inner cavity with the box body 711. The box cover 712 is detachably connected to the box body 711. The box body 711 and the box cover 712 can be screwed.

[0074] like Figure 4 As shown, a partition 71213 is provided inside the box cover 712, and the partition 71213 can be configured as a flat plate structure. The box cover 712 can be configured as a hood-like structure, and the partition 71213 is connected to the top wall of the box cover 712 and the two opposite side walls of the box cover 712. The partition 71213 separates the inner cavity enclosed by the box cover 712 and the box body 711 into a first heat dissipation cavity 701 and a second heat dissipation cavity 702. The volume of the first heat dissipation cavity 701 can be smaller than the volume of the second heat dissipation cavity 702. The box cover 712 is recessed inward to form a ventilation groove 71221, and the ventilation groove 71221 is located on the wall surface of the second heat dissipation cavity 702. The ventilation groove 71221 can be configured as a strip-shaped through groove. The ventilation slot 71221 may be arranged on the top wall of the box cover 712 and recessed in the direction of the box body 711, and the ventilation slot 71221 extends from one end of the top wall of the box cover 712 to the other end of the top wall of the box cover 712. The extension direction of the ventilation slot 71221 may be substantially the same as the extension direction of the first heat dissipation cavity 701. The cover plate 713 is connected to the box cover 712. The cover plate 713 and the box cover 712 may be screwed, riveted or welded. The cover plate 713 covers the opening of the ventilation slot 71221, and the plate surface of the cover plate 713 facing the ventilation slot 71221 and the inner wall of the ventilation slot 71221 enclose a heat dissipation channel 700.

[0075] The circuit board 721 is disposed in the inner cavity between the box cover 712 and the box body 711. The circuit board 721 is laid in the box body 711. The circuit board 721 is connected to the box body 711. One board surface of the circuit board 721 faces the box body 711, and the other board surface faces the partition 71213, and is sandwiched between the partition 71213 and the box body 711.

[0076] The box body 71 of this structure facilitates the disassembly and assembly of the electronic control board and the radiator 73. At the same time, the heat dissipation channel 700 is enclosed by the cover plate 713 and the ventilation grooves 71221 on the box cover 712, which reduces the difficulty of processing the heat dissipation channel 700 of the box body 71 and ensures the air tightness of the second heat dissipation cavity 702 of the box body 71.

[0077] In an illustrative embodiment, Figure 5 As shown, the box cover 712 includes an insulating box cover 7121 and a metal box cover 7122. The box body 711 includes an insulating box body 7111 and a metal box body 7112.

[0078] The insulating box cover 7121 is made of insulating material, such as plastic. The edge box cover 712 covers the insulating box body 7111 and encloses an inner cavity with the insulating box body 7111. The partition 71213 is arranged on the insulating box cover 7121 to divide the inner cavity into a first heat dissipation cavity 701 and a second heat dissipation cavity 702. The insulating box cover 7121 is also provided with a first opening 71211 and a second opening 71212. The first opening 71211 and the second opening 71212 are respectively located on opposite sides of the partition 71213. The first opening 71211 is arranged at the top of the insulating box cover 7121. The first opening 71211 is connected to the first heat dissipation cavity 701, and the area of ​​the first opening 71211 can be slightly smaller than the projection area of ​​the first heat dissipation cavity 701 on the top of the box cover 712. The second opening 71212 is connected to the second heat dissipation cavity 702, and the area of ​​the second opening 71212 may be slightly smaller than the projection area of ​​the first heat dissipation cavity 701 on the top of the box cover 712. The second opening 71212 may be configured as a notch, extending from the top of the insulating box cover 7121 to the side wall of the insulating box cover 7121 facing away from the first heat dissipation cavity 701.

[0079] The circuit board 721 is arranged on the bottom wall of the insulating box body 7111 and is contained in the cavity between the insulating box body 7111 and the insulating box cover 7121. The insulating box body 7111 and the insulating box cover 7121 can prevent electric shock accidents caused by leakage of the electric control board. At the same time, the ventilation slot 71221 is arranged on the metal box cover 7122. The metal box cover 7122 has better thermal conductivity and can quickly conduct the heat radiated from the second electrical component 722 to the metal box cover 7122 to the air flowing through the ventilation slot 71221.

[0081] In an illustrative embodiment, Figures 6 to 8 As shown, the exhaust fan 4 includes a fan body 41 and an air outlet interface member 42. The air outlet interface member 42 includes an air outlet pipe interface 421 and a connecting pipe 422. The air outlet pipe interface 421 is configured to be tubular, and one end of the air outlet pipe interface 421 is connected to the fan body 41. An air inlet 4211 is provided on the pipe wall of the air outlet pipe interface 421. The connecting pipe 422 can be configured as a straight pipe. The cross section of the connecting pipe 422 can be rectangular. One end of the connecting pipe 422 is connected to the pipe wall of the air outlet pipe interface 421, and is connected to the air inlet 4211 on the pipe wall of the air outlet pipe interface 421. The air outlet interface member 42 can be an integrally formed structure. One end of the connecting pipe 422 facing away from the air outlet pipe interface 421 is connected to the metal box cover 7122 of the box body 71. One end of the connecting pipe 422 facing away from the air outlet pipe interface 421 is provided with a first inlet 4221 and a second inlet 4222. The first inlet 4221 is connected to the first heat dissipation outlet 704 , and the second inlet 4222 is connected to the second heat dissipation outlet 706 .

[0082] In this way, the air inlet 4211 of the air outlet interface 421 is connected to the first heat dissipation outlet 704 and the second heat dissipation outlet 706 of the box body 71 through the connecting pipe 422, and the structure is simple.

[0083] In an illustrative embodiment, Figure 1 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.

[0084] A plurality of keels 1100 are arranged in parallel and located on the same horizontal plane, and two adjacent keels 1100 are spaced apart. The distance between two adjacent keels 1100 is the same. The spliced ​​decorative panel 1200 is arranged between every two adjacent keels 1100, and is respectively connected to the two keels 1100. The shape of the spliced ​​decorative panel 1200 is not limited, and can be a square or hexahedral shape, etc. As for the fixing method of the keel 1100 on the wall, there is no limitation here. In some schemes, the end of the keel 1100 is fixed to the wall, and a hanging structure is provided on the roof of the kitchen, and the keel 1100 is fixed on the hanging structure, so that the overall ceiling 1000 is hung.

[0085] A slot is provided on the keel 1100. The extending direction of the slot on the keel 1100 is the same as the extending direction of the keel 1100. The slot is a straight slot. The opening of the slot faces downward. The slot can be elastically deformed to open the opening. The slot is usually used to connect the spliced ​​decorative panel 1200. The edge of the spliced ​​decorative panel 1200 is provided with an upwardly protruding rib, which is inserted into the slot of the keel 1100 from the bottom of the keel 1100. The slot can clamp the rib to fix the spliced ​​decorative panel 1200 on the keel 1100.

[0086] like Figure 1 , 9 As shown, the air conditioner 100 also includes a housing 1. The housing 1 can be constructed as a box-shaped or box-shaped structure. The housing 1 contains other functional components of the air conditioner 100. The housing 1 is the skeleton structure of the air conditioner 100, supporting other components of the air conditioner 100. The housing 1 can be made of metal material. The housing 1 of the air conditioner 100 can be hoisted on the top wall of the indoor space and embedded in the interlayer space between the ceiling 1000 and the top wall of the indoor space. 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.

[0087] According to the existing technical solution, when the integrated kitchen air conditioner is installed in front, it is necessary to install the body first and then install the ceiling. Or install part of the keel on the ceiling first, then hoist the body, and then install the remaining keel and spliced ​​decorative panels. When the integrated kitchen air conditioner is installed in 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. When the kitchen air conditioner needs to be cleaned or maintained, at least part of the spliced ​​decorative panels need to be removed. If the machine needs to be disassembled for maintenance, the keel on the ceiling also needs to be removed. This makes the cleaning and maintenance of the kitchen air conditioner very time-consuming and labor-intensive, and the operation is cumbersome.

[0088] The present application solution can solve the above problems. Since the top of the housing 1 of the air conditioner 100 is provided with a clearance groove 14, the clearance groove 14 can allow the keel 1100 to pass through. When installing the air conditioner 100, it is only necessary to align the opening of the clearance groove 14 with the keel 1100 below the ceiling 1000, and then raise the height of the air conditioner 100 so that the keel 1100 enters the clearance groove 14 until the keel 1100 is located at the bottom of the clearance groove 14. Finally, the air conditioner 100 is fixed, such as the kitchen air conditioner 100 is hoisted and fixed to complete the installation. During the installation of the air conditioner 100, it is not necessary to remove the installed keel 1100. 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 1000, 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 1100 during the disassembly process of the air conditioner 100. Compared with the prior art solutions, the air conditioner 100 of the embodiment of the utility model reduces the repair steps and time, and improves the maintenance efficiency.

[0089] In an illustrative embodiment, the fan body 41 of the exhaust fan 4 and the box body 711 of the box body 71 of the electric control box 7 are both connected to the housing 1. The clearance slot 14 is located between the fan body 41 and the box body 71. The connecting pipe 422 spans the clearance slot 14. The keel passing through the clearance slot 14 passes from below the connecting pipe 422. The air outlet pipe interface 421 is detachably connected to the fan body 41, and the connecting pipe 422 is detachably connected to the box body 71. The air outlet pipe interface 421 and the fan body 41 can be screwed. The connecting pipe 422 and the metal box cover 7122 of the box body 71 can be screwed.

[0090] Before the housing 1 of the air conditioner 100 is embedded and installed on the ceiling, the air outlet interface 42 is not assembled on the air conditioner 100 to avoid interference between the connecting pipe 422 and the keel 1100. After the housing 1 of the air conditioner 100 is embedded and installed on the ceiling, the air outlet pipe interface 421 is connected to the fan body 41, and the connecting pipe 422 is connected to the box body 71, so that the assembly of the air conditioner 100 can be completed.

[0091] In an illustrative embodiment, Figures 10-12As shown, a first cavity 110 and a second cavity 120 are provided in the housing 1. The first cavity 110 and the second cavity 120 are 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. The first cavity 110 and the second cavity 120 are arranged on the same horizontal plane. The first cavity 110 and the second cavity 120 are separated. The first cavity 110 and the second cavity 120 can be configured as a roughly right hexahedron. The housing 1 is provided with a first air inlet 101, a first air outlet 102, a second air inlet 103 and a second air outlet 104. The first air inlet 101 is arranged 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 arranged 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 arranged 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 arranged 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 exhaust fan 4.

[0092] The air conditioner 100 further includes an air supply fan 2 , a first heat exchanger 3 , a second heat exchanger 5 and a compressor 6 .

[0093] The air supply fan 2 is connected to the housing 1. The air supply fan 2 is arranged in the first cavity 110. The air supply 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 air supply fan 2 is provided with a first air inlet 211 and a first air outlet 213. When the air supply 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 air supply fan 2 is connected to the bottom wall of the first cavity 110. The first air outlet 213 of the air supply fan 2 is connected to the first air outlet 102 of the first cavity 110, and the first air inlet 211 of the air supply fan 2 is connected to the internal space of the first cavity 110. When the air supply 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 air supply 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.

[0094] The first heat exchanger 3 is disposed in the first cavity 110. The first heat exchanger 3 may be disposed on a side of the air supply fan 2 close to the first air inlet 101. The air in the first cavity 110 flows through the first heat exchanger 3 when flowing from the first air inlet 101 to the first air outlet 102, and the first heat exchanger 3 can exchange heat with the air.

[0095] The exhaust fan 4 may be arranged at the second air outlet 104. The exhaust 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 exhaust fan 4 is provided with a second air inlet 411 and a second air outlet 413. The second air outlet 413 is arranged at one end of the air outlet pipe interface 421. The second air outlet 104 of the second cavity 120 is connected to the second air inlet 411 of the exhaust fan 4. When the exhaust fan 4 is in operation, the air can be sucked from the second air inlet 411 and then output from the second air outlet 413. The second air inlet 411 of the exhaust fan 4 is connected to the second air outlet 104 of the second cavity 120, and the second air outlet 413 of the exhaust fan 4 is used to connect to the outdoor space. When the exhaust 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 exhaust 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 exhaust 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 exhaust fan 4 is transported to the side of the housing 1 through the second air outlet 413.

[0096] The second heat exchanger 5 is disposed in the second cavity 120. The second heat exchanger 5 may be disposed between the second air inlet 103 and the second air outlet 104. The air in the second cavity 120 flows through the second heat exchanger 5 when flowing from the second air inlet 103 to the second air outlet 104, and the second heat exchanger 5 can exchange heat with the air.

[0097] The compressor 6 may be arranged in the housing 1. The compressor 6 may be arranged in the first cavity 110 or in the second cavity 120. In the present embodiment, the compressor 6 is arranged in the second cavity 120. The compressor 6 is connected to the first heat exchanger 3 and the second heat exchanger 5 through the refrigerant pipe 9. The refrigerant pipe 9, the first heat exchanger 3 and the second heat exchanger 5 may be pre-filled with refrigerant. The compressor 6 can drive the refrigerant to circulate between the first heat exchanger 3 and the second heat exchanger 5, so that heat is transferred between the first heat exchanger 3 and the second heat exchanger 5 with the refrigerant as a carrier. In the cooling mode of the air conditioner 100, the first heat exchanger 3 acts as an evaporator and the second heat exchanger 5 acts as a condenser. When the refrigerant flows through the first heat exchanger 3, it evaporates and absorbs the heat of the air flowing through the first cavity. When the refrigerant flows through the second heat exchanger 5, it releases heat to the air flowing through the second cavity 120 and condenses. In this way, the temperature of the air flowing through the first cavity decreases, and the air transported 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 120 increases, and the air transported to the outside from the second cavity 120 is hot air.

[0098] In this way, the air supply fan 2, the exhaust fan 4, the first heat exchanger 3, the second heat exchanger 5 and the compressor 6 are all installed on the housing 1, and the air conditioner 100 is constructed as an integrated machine, and the structure of this air conditioner 100 is simple, and can achieve efficient production and quick installation. At the same time, after the housing 1 of this air conditioner 100 is embedded and installed on the ceiling 1000, the first air inlet 101, the second air inlet 103, and the second air outlet 104 are all located above the ceiling 1000, and 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 1000, which is more beautiful. The exhaust 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.

[0099] In an illustrative embodiment, the air conditioner 100 further includes a throttling element. The throttling element may be an electronic expansion valve or a capillary tube. The throttling element may be disposed in the second cavity 120 and close to the compressor 6. The compressor 6, the second heat exchanger 5, the throttling element and the first heat exchanger 3 are connected in sequence to form a refrigeration circuit.

[0100] In this way, when the air conditioner 100 is in the cooling mode, the compressor 6 compresses the refrigerant and then outputs the high-temperature and high-pressure refrigerant to the second heat exchanger 5. When the refrigerant flows through the second heat exchanger 5, the heat is transferred to the air flowing through the second cavity 120, and the refrigerant is cooled to a low-temperature refrigerant. The low-temperature refrigerant is transported from the second heat exchanger 5 to the throttling element, and the throttling element throttles and reduces the pressure of the liquid refrigerant. The refrigerant is then transported to the first heat exchanger 3, where it absorbs the heat of the air flowing through the first cavity 110 and evaporates. The refrigerant then flows back to the compressor 6 to complete a cycle.
