[0064] like Figures 3 to 7 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.

[0065] 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.

[0066] The keel 1100 is provided with a slot 1101. The extending direction of the slot 1101 on the keel 1100 is the same as the extending direction of the keel 1100. The slot 1101 is a straight slot. The opening of the slot 1101 faces downward. The slot 1101 can be elastically deformed to open the opening. The slot 1101 is usually used to connect the splicing decorative panel 1200. The edge of the splicing decorative panel 1200 is provided with an upwardly protruding rib, which is inserted into the slot 1101 of the keel 1100 from the bottom of the keel 1100. The slot 1101 can clamp the rib to fix the splicing decorative panel 1200 on the keel 1100.

[0067] like Figure 1 As shown, Figure 1 The structure of an air conditioner 100 in this embodiment is shown. The air conditioner 100 may be a kitchen air conditioner. The air conditioner 100 includes a main unit 1B and a panel 1A.

[0068] The host 1B includes a housing 1. The housing 1 may be constructed as a box-shaped or box-shaped structure. The housing 1 contains other functional components of the host 1B. The housing 1 is a skeleton structure of the host 1B, supporting other components of the host 1B. The housing 1 may be made of metal or plastic material. The housing 1 of the host 1B may 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.

[0069] The panel 1A includes a panel body 11A and a clip 12A. The panel body 11A can be constructed in a roughly flat plate shape, such as a rectangular plate structure. The area of ​​the panel body 11A is larger than the area of ​​the bottom of the shell 1. The panel body 11A can cover the bottom surface of the shell 1 and completely shield the bottom surface of the shell 1. After the panel 1A is installed on the shell 1, the user can only see the panel 1A from below, but cannot see the host 1B, and the panel 1A plays a role in decorating the host 1B. The panel body 11A is arranged roughly horizontally. The clip 12A extends upward from the panel body 11A. The clip 12A can be constructed in a flat plate shape. The board surface of the clip 12A is perpendicular to the board surface of the panel body 11A. The clip 12A is used to be inserted into the card slot 1101 of the keel 1100. In this embodiment, the clamping bar 12A is inserted into the clamping slot 1101 of the keel 1100 from below the keel 1100, and the clamping slot 1101 of the keel 1100 can clamp the clamping bar 12A to fix the panel 1A on the keel 1100. The panel body 11A and the housing 1 of the host 1B can be connected by screws.

[0070] In this way, after the host 1B of the air conditioner 100 is embedded and installed in the interlayer space above the ceiling 1000, when continuing to install the panel 1A, it is only necessary to insert the clamping rib 12A of the panel 1A into the clamping groove 1101 of the keel 1100, so that the clamping groove 1101 of the keel 1100 clamps the clamping rib 12A, thereby fixing the panel 1A on the keel 1100. When the panel body 11A is connected with the housing 1 of the host 1B by screws, since the panel 1A has been fixed on the keel 1100, it is not necessary to hold the panel 1A when tightening the screws, and the installation of the panel 1A is simpler and more convenient, thereby improving the installation efficiency of the panel 1A of the air conditioner 100.

[0071] In an exemplary embodiment, two clip ribs 12A are provided. The two clip ribs 12A are respectively provided at two opposite ends of the panel body 11A. The two clip ribs 12A extend upward from two opposite ends of the panel body 11A.

[0072] The two clamping ribs 12A can be respectively inserted into the clamping grooves 1101 of the two keels 1100. After the two clamping ribs 12A are inserted into the two keels 1100, the panel body 11A is lifted from both ends of the panel body 11A, and the connection between the panel 1A and the keels 1100 is more stable.

[0073] In an exemplary embodiment, the clip 12A is configured as a straight strip rib. The two clips 12A may extend along two opposite edges of the panel body 11A, respectively, from one end of the panel body 11A to the other end of the panel body 11A. The two clips 12A extend in the same direction.

[0074] The clip 12A is constructed as a straight rib. The long clip 12A can increase the contact area with the slot 1101 of the keel 1100, improve the connection strength between the clip 12A and the keel 1100, and make the panel 1A be installed more firmly.

[0075] In an illustrative embodiment, Figure 5 , 7 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 extension direction of the two clamping ribs 12A is the same as the extension direction of the clearance groove 14.

[0076] 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.

[0077] The present application can solve the above problems. Since the top of the housing 1 of the main unit 1B 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 main unit 1B, 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 main unit 1B 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 main unit 1B can be fixed, for example, by hoisting and fixing the main unit 1B to complete the installation. During the installation of the main unit 1B, it is not necessary to remove the installed keel 1100. After the main unit 1B 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 host 1B needs to be repaired, it is only necessary to release the fixing of the host 1B and vertically lower the height of the host 1B to disassemble the host 1B, and it is not necessary to disassemble the installed keel 1100 during the disassembly process of the host 1B. Compared with the prior art solutions, the air conditioner 100 of the embodiment of the present invention reduces the repair steps and time, and improves the maintenance efficiency.

[0078] At the same time, the extension direction of the clamping rib 12A of the panel 1A is set to be parallel to the extension direction of the clearance groove, and the clamping rib 12A can also be inserted into the clamping groove 1101 of the keel 1100 adjacent to the shell 1, so as to fix the panel 1A.

[0079] In an illustrative embodiment, Figure 2 As shown, the panel body 11A includes a substrate 111A and a fence 112A. The substrate 111A may be a flat plate configured to be arranged horizontally. The shape of the substrate 111A is the same as the shape of the bottom of the housing 1. The substrate 111A covers the bottom end of the housing 1. The fence 112A is arranged on the edge of the substrate 111A and extends upward from the edge of the substrate 111A. The fence 112A may be annular, for example, the horizontal cross section is a quadrilateral, and surrounds the bottom end of the housing 1. The fence 112A is connected to the housing 1 by screws. The clamp 12A is arranged on the outer side of the end of the fence 112A facing away from the substrate 111A, and extends upward from the end of the fence 112A facing away from the substrate 111A. The inner side of the end of the fence 112A facing away from the substrate 111A may abut against the edge of the lower surface of the splicing decorative panel 1200 of the ceiling 1000.

[0080] In this way, the panel body 11A is constructed as a roughly square disc structure, and accommodates the bottom end of the housing 1, which can completely cover the bottom end of the housing 1 extending below the ceiling 1000, making the air conditioner 100 more beautiful. At the same time, the clamping rib 12A is set at the top of the enclosure 112A, and the clamping rib 12A can be completely extended into the clamping groove 1101 of the keel 1100 without being exposed to the outside, thereby improving the appearance.

[0081] In an illustrative embodiment, a groove 1121A is provided on the enclosure 112A. The groove 1121A is recessed toward one side of the shell 1. A mounting hole 1122A is provided on the groove 1121A. The mounting hole 1122A is a through hole that passes through the groove 1121A in the horizontal direction. A screw hole 130 is provided on the shell 1. The screw hole 130 is provided on the side of the shell 1. The screw hole 130 is aligned with the mounting hole 1122A. The screw hole 130 is provided with an internal thread. The depth direction of the screw hole 130 is the same as the depth direction of the mounting hole 1122A with which it is aligned.

[0082] The air conditioner 100 further includes a screw which passes through the mounting hole 1122A on the slot 1121A and is screwed into the screw hole 130 on the housing 1 , thereby screwing the panel 1A to the housing 1 .

[0083] In this way, the head of the screw is located in the slot 1121A, and the user cannot see the screw from below, which is more beautiful. In some examples, the panel body 11A may also include a cover, and the slot 1121A may also cooperate with the cover. The cover can cover the opening of the slot 1121A to close the slot 1121A, hide the screw and the mounting hole 1122A inside the cover, and make the periphery of the enclosure 112A more beautiful. The cover can be detachably matched with the slot 1121A by means of snap connection or the like.

[0084] In an exemplary embodiment, the mounting hole 1122A on the enclosure 112A is a bar-shaped hole. The cross section of the mounting hole 1122A is a straight bar shape and extends in the vertical direction.

[0085] Since the mounting holes 1122A on the enclosure 112A are configured as strip holes, the panel 1A can have a certain matching margin relative to the shell 1 in the vertical direction during installation, and can adapt to ceilings 1000 of different thicknesses, thereby expanding the applicable scenarios of the air conditioner 100.

[0086] In an exemplary embodiment, the panel 1A is provided with two slots 1121A, and the two slots 1121A are respectively provided on two opposite sides of the enclosure 112A.

[0087] There are multiple screw holes 130 on the housing 1, and the number of screw holes 130 is the same as the number of mounting holes 1122A on the slot body 1121A. The multiple screw holes 130 are aligned one by one with the multiple mounting holes 1122A on the two slot bodies 1121A. In this embodiment, two mounting holes 1122A are provided on each slot body 1121A, and the number of screw holes 130 is 4. The two screw holes 130 are aligned with the two mounting holes 1122A on one slot body 1121A, and the other two screw holes 130 are aligned with the two mounting holes 1122A on the other slot body 1121A.

[0088] There are multiple screws. The multiple screws pass through the multiple mounting holes 1122A and are screwed into the multiple screw holes 130. In this embodiment, there are four screws, which pass through the four mounting holes 1122A on the panel 1A and are screwed into the four screw holes 130 on the housing 1.

[0089] In this way, a plurality of screws connect the opposite sides of the panel 1A to the opposite sides of the housing 1 , and the panel 1A can be fixed more firmly.

[0090] The enclosure 112A includes two groups of opposite enclosures, one group of which is connected to the clip 12A, and the other group of which is connected to the shell 1. Two grooves 1121A for connecting the shell 1 can be respectively arranged on the opposite sides of the enclosure 112A that are not connected to the clip 12A. Each group of enclosures can include two enclosures located on opposite sides. One group of enclosures is connected to the clip 12A to connect to the keel 1100, allowing the group of enclosures to be slightly deformed so as to be aligned with the keel 1100; the other group of enclosures is provided with the groove 1121A to connect to the shell 1, allowing the enclosures on the other two opposite sides of the other group to be slightly deformed so as to fit with the outer side of the shell 1.

[0091] In an illustrative embodiment, a first air outlet 102 is disposed at the bottom end of the housing 1. The first air outlet 102 supplies air downward.

[0092] An air outlet hole 1111A is provided on the panel body 11A. The air outlet hole 1111A may be a vertically penetrating substrate 111A. The shape of the air outlet hole 1111A is the same as the shape of the first air outlet 102 of the shell 1, and both may be rectangular openings. The air outlet hole 1111A is aligned with the first air outlet 102 of the shell 1. The first air outlet 102 of the shell 1 is connected to the indoor space through the air outlet hole 1111A of the panel 1A, so that the first air outlet 102 can supply air to the indoor space. The first air outlet 102 of the host 1B supplies air to the bottom of the shell 1, which can quickly adjust the temperature of the space below the ceiling 1000 and improve the user experience.

[0093] In an illustrative embodiment, Fig.14 , 16As 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 second fan 4.

[0094] The main unit 1B further includes a first fan 2 , a second fan 4 , a first heat exchanger 3 , a second heat exchanger 5 and a compressor 6 .

[0095] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] In this way, the first fan 2, the second fan 4, the first heat exchanger 3, the second heat exchanger 5 and the compressor 6 are all installed on the housing 1, and the 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. 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 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 host 1B in the vertical direction.

[0101] 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 first cavity 110. In this embodiment, Figure 1 , 2As 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.

[0102] In this way, at least part of the first air inlet 101 and at least part of the second air inlet 103 are respectively located on opposite sides of the shell 1, and air is taken in from opposite sides of the shell 1, respectively, so as to avoid mutual influence between the air intake 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 shell 1, or can be connected with an air intake duct. When one of the first air inlet 101 and the second air inlet 103 is connected with the air intake duct, the air intake duct will not block the other of the first air inlet 101 and the second air inlet 103, thereby affecting the air intake. In addition, the first air inlet 101 and the second air inlet 103 can be set larger, and the air intake volume of the first cavity 110 and the second cavity 120 can be increased accordingly, and the size of the shell 1 of the host 1B can be reduced while ensuring the heat exchange efficiency of the first heat exchanger 3 and the second heat exchanger 5, so that the structure of the host 1B is more compact.

[0103] In an illustrative embodiment, Fig.11 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.

[0107] In an illustrative embodiment, Figures 10-12 As shown, 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 configured as a rectangular plate. The partition 114 is vertically arranged. The partition 114 extends upward from the boundary between the first area 131 and the connection area 132 of the chassis 13.

In this embodiment, a flange can be provided at the bottom end of the partition 114 close to the chassis 13, the flange abuts against the chassis 13, and the flange is connected to the chassis 13 by screws.

[0108] like Fig.19As 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.

[0109] like Fig.23 As shown, the second plate 113 is constructed as a flat plate, which can be a rectangular flat plate. The second plate 113 is arranged at the edge of the first area 131 facing away from the second side plate 1122. The second plate 113 is arranged vertically. The second plate 113 extends from the end of the first side plate 1121 facing away from the second side plate 1122 along the edge of the first area 131 to the end of the partition 114 facing away from the second side plate 1122. The second side plate 1122 is connected to the first side plate 1121 and the partition 114. The first side plate 1121 and the partition 114 are connected to the second side plate 1122 by screws, welding or riveting. In this embodiment, the second plate 113 and the chassis 13 are constructed as an integrally formed structure, which can reduce the assembly steps and enhance the connection strength between the second plate 113 and the chassis 13. The second plate 113 can be more firmly connected to the chassis 13.

[0110] like Fig.10As 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.

[0111] 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.

[0112] In an illustrative embodiment, Fig.17 As shown, the first heat exchanger 3 is constructed as a U-shaped heat exchanger. The first heat exchanger 3 extends from one end of the partition 114 along the second plate 113, the first side plate 1121 and the second side plate 1122 to the other end of the partition 114. The two ends of the first heat exchanger 3 are respectively close to the two ends of the partition 114. The first heat exchanger 3 and the partition 114 enclose an internal cavity. The bottom end of the first heat exchanger 3 is connected to the bottom plate 13.

[0113] like Fig.17 As shown, the first fan 2 is disposed in the internal cavity enclosed by the first heat exchanger 3 and the partition 114. The first air inlet 211 of the first fan 2 is connected to the internal cavity. The first air outlet 213 of the first fan 2 is connected to the first air outlet 102 on the chassis 13.

[0114] The first heat exchanger 3 is constructed in a U shape, has a large contact area with the air, and has a high heat exchange efficiency. Since the first fan 2 is arranged in the internal cavity enclosed by the first heat exchanger 3 and the partition 114, the layout is compact and the first cavity 110 can be reduced accordingly, so that the overall volume of the main unit 1B is smaller.

[0115] In an illustrative embodiment, Fig.18As shown, the first fan 2 includes a first air duct member 21, a first wind wheel 22 and a first motor 23. The first air duct member 21 includes two first volutes 214 and a connecting shell 215. The two first volutes 214 are arranged side by side and spaced apart from each other. The connecting shell 215 connects the two first volutes 214. Each first volute 214 is provided with a first air inlet 211, a first air outlet 213 and a first air duct 212 connecting the first air inlet 211 and the first air outlet 213. The first air outlets 213 of the two first volutes 214 both penetrate the connecting shell 215 and are connected to the first air outlet 102 on the chassis 13. The first air inlets 211 of the two first volutes 214 are both connected to the internal cavity enclosed by the first heat exchanger 3 and the partition 114.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] In an illustrative embodiment, Fig.18 As 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.23 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.

[0120] 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.

[0121] In an illustrative embodiment, Fig.12 , 17 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.

[0122] like Fig.23 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.

[0123] 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.

[0124] like Fig.14 , 16 As 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 .

[0125] like Fig.21 , 22As shown, the second fan 4 includes a second air duct member 41, a second wind wheel 42 and a second motor 43. The second air duct member 41 is provided with a second air inlet 411, a second air outlet 413 and a second air duct 412. The second wind wheel 42 may be a centrifugal wind wheel. The second air duct 412 extends from the second air inlet 411 to the second air outlet 413. The second wind wheel 42 is arranged in the second air duct 412. The body of the second motor 43 is connected to the second air duct member 41. The main shaft of the second motor 43 is connected to the second wind wheel 42. The second motor 43 can drive the second wind wheel 42 to rotate, and when the second wind wheel 42 rotates, it can drive the air in the second air duct 412 to flow from the second air inlet 411 to the second air outlet 413. The second air duct member 41 abuts against the fourth side plate 1222, the fourth plate member 123 and the second top plate 121 at one end facing away from the third side plate 1221, and the second air duct member 41 also abuts against the chassis 13. In this way, the second air duct member 41 can cover the second air outlet 104 of the second housing 12. The second air inlet 411 on the second air duct member 41 is configured to be connected to the second air outlet 104. The second air outlet 413 is configured to be connected to the outdoor space. One end of the outdoor exhaust duct can be connected to the second air outlet 413, and the other end of the outdoor exhaust duct extends to the outdoors. The second air outlet 413 can be connected to the outdoor space through the outdoor exhaust duct.

[0126] like Fig.14 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 .

[0127] The second heat exchanger 5 is disposed in the second cavity 120 and sandwiched between the second air duct member 41 and the third side plate 1221. The opposite sides of the second heat exchanger 5 are respectively connected to the second air inlet 411 of the second air duct member 41 and the second air inlet 103 of the third side plate 1221. The second heat exchanger 5 can be a straight heat exchanger with multiple rows, and the second air inlet 411 faces the second heat exchanger 5.

[0128] 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 host 1B in the width direction of the make way slot 14, making the volume of the host 1B smaller.

[0129] In an illustrative embodiment, Fig.23 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.

[0130] 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.

[0131] 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 main unit 1B in the vertical direction.

[0132] In an illustrative embodiment, Fig.21 , 22 As shown, the second air duct member 41 includes a first plate body 414, a second plate body 415 and a second volute 416. The first plate body 414 and the second plate body 415 are constructed in a flat plate shape. The first plate body 414 extends from the boundary between the second area 133 and the connection area 132 to the second top plate 121. The first plate body 414 and the second plate body 415 are parallel to each other and spaced apart from each other. The second plate body 415 is arranged on a side of the first plate body 414 close to the second heat exchanger 5. The second volute 416 is arranged between the first plate body 414 and the second plate body 415, and the first plate body 414 and the second plate body 415 cover the opposite ends of the second volute 416 respectively. The second air duct 412 is arranged in the second volute 416. The second air outlet 413 is arranged on the peripheral wall of the second volute 416. The second air inlet 411 is arranged on the second plate body 415. The second wind wheel 42 is disposed in the second volute 416, the second motor 43 is disposed in the second wind wheel 42, the body of the second motor 43 is connected to the first plate 414, and the main shaft of the second motor 43 is connected to the second wind wheel 42. The lower end of the second volute 416 extends into the clearance opening 1331 of the chassis 13. The structure of the second fan 4 is more compact.

[0133] In an illustrative embodiment, Fig.23 , 24As shown, the upper surface of the chassis 13 of the housing 1 is also provided with a water collecting trough 134, a water drawing trough 136 and a water diversion trough 135. The water collecting trough 134 is provided in the first area 131 of the chassis 13 and is located below the first heat exchanger 3. The shape of the water collecting trough 134 may be the same as the shape of the projection of the first heat exchanger 3 on the chassis 13, for example, both are constructed in a U shape. The water drawing trough 136 is provided in the second area 133 of the chassis 13 and is located below the second heat exchanger 5. The height of the bottom of the water collecting trough 134 may be greater than or equal to the height of the bottom of the water drawing trough 136. The water diversion trough 135 extends from the water collecting trough 134 to the water drawing trough 136. The water diversion trough 135 connects the water collecting trough 134 and the water drawing trough 136. The height of the bottom of the water drawing trough 135 may have a tendency to decrease in the direction extending from the water collecting trough 134 to the water drawing trough 136.

[0134] like Fig.23 , 25 As shown, the main unit 1B further includes a water pumping assembly 7. The water pumping assembly 7 is disposed on the chassis 13. The water pumping assembly 7 may be disposed in the second area 133. The water pumping assembly 7 includes a water pumping wheel 71 and a water pumping motor 72. The water pumping wheel 71 is constructed to be roughly disc-shaped. The water pumping wheel 71 is disposed above the chassis 13. The axis of the water pumping wheel 71 is disposed horizontally, and the water pumping wheel 71 at least partially extends into the water pumping trough 136. The water pumping motor 72 is transmission-connected to the water pumping wheel 71. The water pumping motor 72 can drive the water pumping wheel 71 to rotate.

[0135] When the air conditioner 100 is operated in the cooling mode, the temperature of the first heat exchanger 3 is lower than the temperature of the air flowing through the first cavity 110. The water vapor in the air is pre-cooled and condensed on the surface of the first heat exchanger 3 to form condensed water droplets. The condensed water droplets on the surface of the first heat exchanger 3 are dripped into the water collecting tank 134 under the action of force and collected. The condensed water in the water collecting tank 134 flows into the water pumping tank 136 along the water guide tank 135. Since the water pumping wheel 71 extends into the water pumping tank 136, it can contact the condensed water in the water pumping tank 136. When the water pumping motor 72 drives the water pumping wheel 71 to rotate, the condensed water in the water pumping tank 136 can be thrown onto the second heat exchanger 5. When the air conditioner 100 is operated in the cooling mode, the surface temperature of the second heat exchanger 5 is relatively high, and heat can be released to the condensed water to evaporate the condensed water. When the condensed water is evaporated, it absorbs the heat released by the second heat exchanger 5, thereby improving the heat exchange efficiency of the second heat exchanger 5, and then 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 water tank 136 can be reduced, avoiding the overflow of the condensed water in the chassis 13. Therefore, there is no need to set a drain pipe to lead the condensed water in the chassis 13 out of the main unit 1B.

[0136] In an illustrative embodiment, Fig.23As shown, the main unit 1B further includes a water level switch 8. The water level switch 8 can be disposed in the water tank 136, or can be disposed at one end of the water tank 135 close to the water tank 136. The water level switch 8 can detect whether the water level in the water tank 136 or the water tank 135 reaches a preset threshold. The water level switch 8 is configured to shut down the compressor 6 after detecting that the water level in the water tank 136 or the water tank 135 reaches a preset threshold.

[0137] The preset threshold value can be set to be slightly less than the water level height at the water level switch 8 when the condensed water overflows from any one of the water-drawing tank 136, the water-collecting tank 134 and the water-introducing tank 135. When the water level in the water-drawing tank 136 or the water-introducing tank 135 reaches the preset threshold value, it means that the condensed water is at risk of overflowing the water-drawing tank 136, the water-collecting tank 134 or the water-introducing tank 135. At this time, the compressor 6 is turned off, so that the rate at which the first heat exchanger 3 produces condensed water decreases, and at the same time, the water-drawing wheel 71 is kept rotating to continuously consume the condensed water that has been produced, which can prevent the condensed water from overflowing when the air humidity is very high.

[0138] In an illustrative embodiment, Fig.23 As shown, a collecting tank 137 is also provided on the chassis 13. The collecting tank 137 is located below the second heat exchanger 5. The water tank 136 and the collecting tank 137 are arranged in sequence in the flow direction of the air in the second cavity, for example, in the direction from the second air inlet 103 to the second air outlet 104. The extension direction of the water tank 136 and the extension direction of the collecting tank 137 can be perpendicular to the flow direction of the air in the second cavity. The water tank 136 and the collecting tank 137 are separated by a baffle. A through hole 138 is provided on the baffle. The through hole 138 can be set as a through hole passing through the baffle, or it can be set as a notch passing through the baffle. The position of the through hole 138 can be higher than the bottom of the water tank 136. The through hole 138 can be set in the middle area of ​​the baffle in the vertical direction. The two ends of the through hole 138 are connected to the collecting tank 137 and the water tank 136 respectively.

[0139] In this way, after the water wheel 71 throws out the condensed water, part of the condensed water droplets will be driven by the airflow in the second cavity 120 to move a distance downstream of the airflow. At the same time, the condensed water that is not completely evaporated in the second heat exchanger 5 will also drip downward, and these condensed water droplets will also be driven by the airflow in the second cavity 120 to move a distance downstream of the airflow. Part of the condensed water droplets deflected by the airflow will not fall back into the water trough 136, but fall into the collection trough 137 to be collected, and then flow back from the collection trough 137 to the water trough 136, so as to prevent the condensed water from splashing to other areas of the chassis 13 due to the action of wind and causing the condensed water to overflow.

[0140] 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.

[0141] 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 main unit 1B more compact.

[0142] In an illustrative embodiment, the second heat exchanger 5 includes a plurality of heat exchange tube rows, and the number of heat exchange tube rows is at least four. These heat exchange tube rows are arranged in sequence along the air flow direction in the second cavity 120. The heat exchange channels of the plurality of heat exchange tube rows are connected in series in sequence according to the arrangement direction of the heat exchanger.

[0143] In this way, the second heat exchanger 5 is provided with more than four heat exchange tube rows for heat exchange, so the heat exchange efficiency is higher and the cooling capacity is larger in the cooling mode.

[0144] In an illustrative embodiment, Fig.17 As shown, the compressor 6 is arranged in the second cavity 120 of the housing 1. The compressor 6 is located at an end of the second fan 4 facing away from the second air outlet 413. The compressor 6 can be arranged at an end of the second fan 4 facing away from the fourth plate 123. The second heat exchanger 5 is arranged on a side of the second fan 4 facing away from the first cavity 110. The compressor 6 can be arranged at an end of the second heat exchanger 5 facing away from the fourth plate 123.

[0145] 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 main unit 1B more compact and smaller in size.

[0146] In an exemplary embodiment, the host 1B 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.

[0147] In some embodiments, the compressor 6, the second heat exchanger 5, the throttling element and the first heat exchanger 3 are connected in sequence to form a refrigeration circuit.

[0148] 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 refrigerant. Then, the refrigerant is transported to the first heat exchanger 3, where it absorbs the heat of the air flowing through the first cavity 110 and evaporates. The refrigerant then flows back to the compressor 6 to complete a cycle.
