DETAILED DESCRIPTION

[0047] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0048] Hereinafter, an air conditioner 100 according to an embodiment of the present application will be described with reference to the accompanying drawings.

[0049] As shown in Figures 1 to 9, the air conditioner 100 according to the embodiment of the present application includes: a condensate recovery system 4, a heat-conducting structure 5 and a heat exchange pipe 6, the condensate recovery system 4 includes a water pipe 41 and a spray head 42, the spray head 42 is connected to the end of the water pipe 41; and the heat-conducting structure 5 is thermally coordinated with the water pipe 41; the heat exchange pipe 6 is thermally coordinated with the heat-conducting structure 5, and the heat exchange pipe 6 and the water pipe 41 exchange heat through the heat-conducting structure 5.

[0050] As a result, the heat-conducting structure 5 can fully transfer the heat of the heat exchange tube 6 to the water pipe 41 to prevent the water pipe 41 from being frozen and blocked when the ambient temperature is low, thereby ensuring the working stability of the spray head 42. The heat-conducting structure 5 has high heat conduction efficiency, which is conducive to improving energy utilization.

[0051] First, as shown in Figures 1 to 3, the air conditioner 100 is provided with a condensate recovery system 4, which includes a water pipe 41 and a spray head 42. The air conditioner 100 can collect the generated condensate and introduce the condensate into the water pipe 41. The end of the water pipe 41 is connected to the spray head 42, and the spray head 42 is connected to the outdoors. The condensate can flow along the water pipe 41 and spray toward the outdoors from the spray head 42, thereby consuming the collected condensate.

[0052] For example, the air conditioner 100 may include a water receiving pan for receiving condensed water. The water receiving pan may be installed in at least one of the outdoor unit 1 and the indoor unit 2 of the air conditioner 100 .

[0053] Among them, the air conditioner 100 also includes a heat-conducting structure 5 and a heat exchange tube 6. The heat-conducting structure 5 can be made of a high thermal conductivity material such as metal or ceramic. The heat-conducting structure 5 is used to fit on the outer wall of the water pipe 41 and cooperate with the water pipe 41 for thermal conductivity. The heat exchange tube 6 is used to contact the heat-conducting structure 5 and cooperate with the heat-conducting structure 5 for thermal conductivity. For example, the heat exchange tube 6 can generate heat. When the ambient temperature is low, the heat exchange tube 6 can heat the water pipe 41 through the heat-conducting structure 5. It should be noted that the heat source of the heat exchange tube 6 is not limited. For example, it can exchange heat with the motor or electronic control of the air conditioner to absorb heat, or the heat exchange tube 6 can be set as the high-temperature part of the refrigerant pipe section, or the heat exchange tube 6 can be set as an electric heating element. This application does not impose any restrictions on this. In this way, the water pipe 41 can be prevented from freezing and clogging when the ambient temperature is low.

[0054] Preferably, a portion of the heat conducting structure 5 can be sleeved on the outside of the water pipe 41, and another portion of the heat conducting structure 5 can be sleeved on the outside of the heat exchange tube 6. In this way, the heat conducting area can be increased and the heat conducting effect can be improved.

[0055] According to the air conditioner 100 of the embodiment of the present application, by providing a heat-conducting structure 5 to cooperate with the water pipe 41 and the heat exchange pipe 6 respectively, the heat-conducting structure 5 can transfer the heat of the heat exchange pipe 6 to the water pipe 41 to achieve heating, thereby avoiding ice and blockage of the water pipe 41 when the ambient temperature is low, ensuring the working reliability of the spray head 42, and preventing condensed water from overflowing. In addition, the heat-conducting structure 5 has a high heat conduction efficiency, which can improve energy utilization.

[0056] In some embodiments of the present application, as shown in Figures 1-3, an air conditioner 100 includes an outdoor unit 1, which is suitable for being located outdoors. A water conduit 41, a spray head 42, and a heat-conducting structure 5 are all located outdoors. This arrangement allows the spray head 42 to spray directly toward the outdoors or toward the outlet of the outdoor fan 17, thereby improving spray efficiency. Furthermore, the heat-conducting structure 5 can better fit the water conduit 41, thereby enhancing its heating effect.

[0057] In some embodiments of the present application, as shown in Figures 2 and 3, the external unit 1 includes a housing 11 and a middle partition 12. The middle partition 12 is disposed within the housing 11, and the heat-conducting structure 5 is disposed on the middle partition 12. For example, a first connecting portion can be provided on the heat-conducting structure 5, and a second connecting portion can be provided on the middle partition 12. The first connecting portion and the second connecting portion are connected by a snap connection or screw connection; alternatively, the heat-conducting structure 5 can be directly snap-connected or screwed to the middle partition 12.

[0058] Through the above arrangement, the space inside the external unit part 1 can be fully utilized, and the heat-conducting structure 5 is less affected by vibration at the middle partition 12, which is unlikely to affect the installation reliability of the heat-conducting structure 5.

[0059] In some embodiments of the present application, the middle partition 12 divides the space inside the outer shell 11 into a first space 13 and a second space 14. The air conditioner 100 includes a compressor 15 and an outdoor heat exchanger 16. The compressor 15 is arranged in the first space 13, the outdoor heat exchanger 16 is arranged in the second space 14, and the heat-conducting structure 5 is arranged in the first space 13 and is higher than the compressor 15.

[0060] For example, as shown in Figure 2 , a central partition 12 extends vertically to separate the space within the housing 11 into a first space 13 and a second space 14, each of which is independently sized according to actual needs. The air conditioner 100 includes an indoor heat exchanger, a compressor 15, and an outdoor heat exchanger 16. The compressor 15 is located within the first space 13, the outdoor heat exchanger 16 is located within the second space 14, and the indoor heat exchanger is located indoors. The outdoor heat exchanger 16, the compressor 15, and the indoor heat exchanger are interconnected via pipes.

[0061] Specifically, when the ambient temperature is low and the air conditioner 100 is in heating mode, the compressor 15 operates to compress the refrigerant. The compressed refrigerant can flow into the indoor heat exchanger to release heat. The refrigerant after releasing heat flows into the outdoor heat exchanger 16 to absorb heat in the second space 14. The refrigerant after absorbing heat flows back into the compressor 15.

[0062] The water pipe 41 and the heat-conducting structure 5 can be arranged to be located in the first space 13 so that the middle partition 12 can separate the water pipe 41 and the heat-conducting structure 5 from the outdoor heat exchanger 16, and the installation position of the heat-conducting structure 5 can be arranged to be higher than the position of the compressor 15.

[0063] It can be understood that since the temperature of the second space 14 is lower in the heating mode, by arranging the heat-conducting structure 5 in the first space 13, the influence of the temperature in the second space 14 on the heat-conducting structure 5 can be reduced, which is beneficial to improving the heating effect of the heat-conducting structure 5 on the water pipe 41, and by setting the heat-conducting structure 5 higher than the compressor 15, the difficulty of installing the heat-conducting structure 5 can be reduced.

[0064] In some embodiments of the present application, as shown in Figures 2 and 3, the air conditioner 100 according to the embodiments of the present application further includes: a mounting bracket 7, to which the heat-conducting structure 5 is mounted. The mounting bracket 7 is mounted on the side of the middle partition 12 facing the first space 13. For example, a connection hole can be provided in the middle partition 12, and the mounting bracket 7 is mounted on the middle partition 12 via a snap-fit ​​structure or a threaded member. In the specific operation process, the mounting bracket 7 is first installed on the middle partition 12, and then the heat-conducting structure 5 is installed on the mounting bracket 7.

[0065] Through the above arrangement, the structures of the middle partition plate 12 and the heat-conducting structure 5 can be simplified, which helps to reduce the difficulty of designing and processing the middle partition plate 12 and the heat-conducting structure 5 and improves the practicality of the air conditioner 100.

[0066] In some embodiments of the present application, a card hole 123 is opened on the middle partition 12, and a buckle 73 is provided on the mounting bracket 7. The buckle 73 is engaged with the card hole 123, and the middle partition 12 and the mounting bracket 7 are connected by a first fastener.

[0067] For example, as shown in Figures 4 to 6, a latch hole 123 can be provided on the middle partition plate 12. The latch hole 123 penetrates the middle partition plate 12 in the thickness direction and extends in the vertical direction. A protruding latch 73 is provided on the side of the mounting bracket 7 facing the middle partition plate 12. The end of the latch 73 is provided with a blocking portion 731. The latch 73 can be engaged in the latch hole 123 through the blocking portion 731 to mount the mounting bracket 7 on the middle partition plate 12. At the same time, the middle partition plate 12 and the mounting bracket 7 can also be connected by a first fastener. It should be noted that the first fastener can be constructed as a bolt, a screw, or a bayonet pin, etc.

[0068] During the specific installation process, the mounting bracket 7 is first installed from one side to the middle partition 12 so that the buckle 73 can pass through the clamping hole 123, so that the blocking portion 731 can extend to the other side of the middle partition 12. The mounting bracket 7 is then driven downward so that the buckle 73 can stop on the inner wall of the buckle 73 and the blocking portion 731 can cooperate with the other side of the middle partition 12 to clamp the buckle 73 in the clamping hole 123, thereby completing the initial installation of the mounting bracket 7. At this time, the mounting bracket 7 can be connected to the middle partition 12 by the first fastener to further fix the mounting bracket 7. Through the above arrangement, the mounting bracket 7 can be quickly assembled and the installation reliability of the mounting bracket 7 can be guaranteed.

[0069] Furthermore, as shown in FIG6 , the clips 73 can be provided in two groups, one on each side of the mounting bracket 7 along the length direction, each group having a plurality of clips 73. The clips 73 in the same group are spaced apart in the vertical direction, and the middle partition plate 12 is provided with a plurality of corresponding locking holes 123. The clips 73 are engaged with the plurality of locking holes 123 one by one. This helps to improve the installation stability of the mounting bracket 7.

[0070] In some embodiments of the present application, the shell 11 includes a panel 111, the middle partition 12 includes a first plate 121 arranged toward the panel 111, and a second plate 122 extending relative to the first plate 121 in a direction away from the panel 111, the mounting bracket 7 includes a first frame plate 71 and a second frame plate 72, the first frame plate 71 abuts against the side of the first plate 121 facing away from the panel 111, and the second frame plate 72 abuts against the thickness side of the second plate 122, the card hole 123 is opened on the second plate 122, the clip 73 is provided on the second frame plate 72, and the first fastener connects the first frame plate 71 and the first plate 121, and / or connects the second frame plate 72 and the second plate 122.

[0071] For example, referring to Figures 1 to 4, the housing 11 includes a panel 111, which is located on the front side of the housing 11. The middle partition 12 includes a first plate 121 and a second plate 122 connected to each other. The first plate 121 is arranged toward the panel 111 and is used to cooperate with the panel 111. The second plate 122 is connected to one side of the first plate 121 along the left-right direction and extends in a direction away from the panel 111 to separate the first space 13 and the second space 14. At the same time, in conjunction with Figure 5, a mounting bracket 7 can be provided including a first frame plate 71 and a second frame plate 72. The first frame plate 71 is arranged on the side of the mounting bracket 7 facing the panel 111, and the first frame plate 71 is used to abut the side of the first plate 121 away from the panel 111. The second frame plate 72 is arranged parallel to the second plate 122 and abuts the thickness side of the second plate 122 (i.e., the side facing the first space 13).

[0072] Specifically, a latch hole 123 may be provided on the second plate 122, and a latch 73 may be provided on the second frame plate 72, so that the second plate 122 and the second frame plate 72 can be connected by the latch 73. Furthermore, a first fastener may be provided for connecting the first frame plate 71 and the first plate 121; or a first fastener may be provided for connecting the second frame plate 72 and the second plate 122; or, a plurality of first fasteners may be provided, with some first fasteners used to connect the first frame plate 71 and the first plate 121, and other first fasteners used to connect the second frame plate 72 and the second plate 122.

[0073] Specifically, as shown in Figures 4-5, a first hole 1211 can be opened on the first plate 121, and a corresponding second hole 712 can be opened on the first frame plate 71, and the first fastener is respectively passed through the first hole 1211 and the second hole 712 to connect the first plate 121 and the first frame plate 71; and / or, a third hole 721 can be opened on the second frame plate 72, and a fourth hole 1221 can be opened on the second plate 122, and the first fastener is respectively passed through the third hole 721 and the fourth hole 1221 to connect the second frame plate 72 to the second plate 122.

[0074] It is understood that by providing the latch hole 123 on the second plate 122, the latch hole 123 can be staggered with respect to the panel 111, eliminating the need for a corresponding avoidance structure for the latch 73 on the panel 111, thereby improving design rationality. In addition, when the first fastener connects the first frame plate 71 and the first plate 121, both the first frame plate 71 and the second frame plate 72 can be connected to the middle partition plate 12, thereby improving the installation stability of the mounting bracket 7.

[0075] In some embodiments of the present application, the bottom of the first plate 121 has a supporting flange 124, the supporting flange 124 is supported on the bottom of the first frame plate 71, the top of the second frame plate 72 has a overlapping flange 74, and the top of the second plate 122 has an installation flange 125, and the overlapping flange 74 overlaps the top of the installation flange 125.

[0076] For example, as shown in Figure 4, a support flange 124 can be provided at the bottom of the first plate 121, and the support flange 124 extends in a direction away from the panel 111. The support flange 124 is used to support the bottom of the first frame plate 71 to support the mounting bracket 7.

[0077] At the same time, as shown in Figures 4 and 5, a mounting flange 125 can be provided on the top of the second plate 122, extending in a direction away from the mounting bracket 7. A lap flange 74 is provided on the top of the second frame plate 72, located above the second plate 122 and extending in a direction close to the second plate 122. The lap flange 74 is used to overlap the top of the second plate 122 and abut against the mounting flange 125, so that the second plate 122 can support the mounting bracket 7. In this way, the installation stability of the mounting bracket 7 can be improved.

[0078] In some embodiments of the present application, the panel 111 has a through-hole 112 , and both the first frame plate 71 and the first plate 121 avoid the spray head 42 so that the spray head 42 is disposed corresponding to the through-hole 112 .

[0079] For example, as shown in Figures 1 and 2, a perforation 112 can be provided on the panel 111. The perforation 112 penetrates the panel 111 along the thickness direction. The first frame plate 71 and the first plate 121 respectively form a through-hole structure corresponding to the perforation 112. The first frame plate 71 and the first plate 121 jointly define an avoidance gap at the through-hole. The spray head 42 can pass through the perforation 112 from the inside of the panel 111 through the avoidance gap and extend to the outside of the panel 111, so that the spray head 42 can directly spray mist toward the outside of the panel 111. Through the above arrangement, the spray head 42 can be conveniently installed and the installation stability of the spray head 42 can be improved.

[0080] In some embodiments of the present application, the air conditioner 100 includes a water receiving pan, and the water pipe 41 is connected to the water receiving pan through a water pump pipeline 8.

[0081] The condensed water recovery system 4 includes a water receiving pan for collecting condensed water, and a water conduit 41 is connected to the water receiving pan via a water pumping line 8. The condensed water in the water receiving pan can flow through the water pumping line 8 to the conduit, and is sprayed outdoors from a spray head 42 along the water conduit 41. In this way, the condensed water generated by the air conditioner 100 can be automatically processed.

[0082] In some embodiments of the present application, the heat-conducting structure 5 includes a first heat-conducting block 51 and a second heat-conducting block 52 that are assembled and connected, and a first tube channel 53 and a second tube channel 54 are defined between the first heat-conducting block 51 and the second heat-conducting block 52. The water pipe 41 is arranged in the first tube channel 53, and the heat exchange pipe 6 is arranged in the second tube channel 54.

[0083] For example, referring to Figures 5 and 8, the heat-conducting structure 5 includes a first heat-conducting block 51 and a second heat-conducting block 52. The first heat-conducting block 51 and the second heat-conducting block 52 are formed separately and are suitable for assembly and connection. When the first heat-conducting block 51 and the second heat-conducting block 52 are assembled, a first tube passage 53 and a second tube passage 54 are defined between the first heat-conducting block 51 and the second heat-conducting block 52.

The second tube passage 54 is provided with a heat exchange tube 6, and the inner peripheral wall of the second tube passage 54 is suitable for thermal coordination with the heat exchange tube 6.

[0084] Through the above arrangement, the heat-conducting structure 5 can fully and evenly guide the heat of the heat exchange tube 6 to the water pipe 41, which is beneficial to improving energy utilization, and can reduce the difficulty of installing and processing the heat-conducting structure 5, thereby improving the practicality of the air conditioner 100.

[0085] In some embodiments of the present application, as shown in Figures 5 and 8 , the first and second tube passages 53 and 54 can be arranged in parallel. Specifically, the portion where the water conduit 41 and the heat-conducting structure 5 are thermally coordinated and the portion where the heat exchange tube 6 and the heat-conducting structure 5 are thermally coordinated can be arranged in parallel. This arrangement can reduce the difficulty of arranging the water conduit 41, the heat exchange tube 6, and the heat-conducting structure 5, ensure uniform heating of the water conduit 41 by the heat exchange tube 6, improve the heating effect, and reduce the overall size of the heat-conducting structure 5.

[0086] In some embodiments of the present application, the air conditioner 100 of the embodiment of the present application further includes: a mounting bracket 7, and the spray head 42 and the heat-conducting structure 5 are separately mounted on the mounting bracket 7. For example, as shown in FIG3 , the air conditioner 100 further includes a mounting bracket 7, and the spray head 42 and the heat-conducting structure 5 can be separately mounted on the mounting bracket 7. Then, the mounting bracket 7 can be mounted on the middle partition 12 of the outdoor unit part 1 to mount the spray head 42 and the heat-conducting structure 5 on the middle partition 12.

[0087] It can be understood that by arranging the spray head 42 and the heat-conducting structure 5 to be installed through the mounting bracket 7, the assembly difficulty can be reduced, the stability of the relative position between the spray head 42 and the heat-conducting structure 5 can be ensured, the mounting structure can be simplified, and the practicality of the air conditioner 100 can be improved.

[0088] In some embodiments of the present application, a slot 75 is formed on the mounting bracket 7, and the thermal conductive structure 5 is inserted into the slot 75 from the notch of the slot 75. The slot side wall 751 of the slot 75 stops the thermal conductive structure 5 to prevent the thermal conductive structure 5 from moving relative to the mounting bracket 7 in a direction perpendicular to the insertion direction of the slot 75.

[0089] For example, referring to Figures 4 and 5, an open slot 75 is formed on the mounting bracket 7, and the thermal conductive structure 5 can be inserted into the slot 75 from the notch of the slot 75, and the slot side wall 751 of the slot 75 can be used to cooperate with the stopper of the thermal conductive structure 5 to prevent the thermal conductive structure 5 from moving relative to the mounting bracket 7 in a direction perpendicular to the insertion direction of the slot 75, thereby fixing the thermal conductive structure 5 on the mounting bracket 7.

[0090] Specifically, as shown in Figures 4 and 5, a slot 75 can be set to open upward, and the heat-conducting structure 5 is suitable for being inserted into the slot 75 through the notch from top to bottom. The mounting bracket 7 includes a second frame plate 72 and a third frame plate 77. The second frame plate 72 and the third frame plate 77 are arranged spaced apart in the left-right direction, and the third frame plate 77 is respectively connected to the fourth frame plate 78 on both sides along the front-back direction. The fourth frame plate 78 is extended in the direction close to the second frame plate 72. The second frame plate 72, the third frame plate 77 and the fourth frame plate 78 jointly define the slot 75. The second frame plate 72 and the third frame plate 77 are used to support the heat-conducting structure 5 on both sides along the left-right direction, and the two fourth frame plates 78 are used to support the heat-conducting structure 5 on both sides along the front-back direction.

[0091] Through the above arrangement, the difficulty of installing the heat-conducting structure 5 can be reduced, and the installation stability of the heat-conducting structure 5 can be improved, which is beneficial to improving the reliability of the air conditioner 100.

[0092] In some embodiments of the present application, the heat-conducting structure 5 includes a first heat-conducting block 51 and a second heat-conducting block 52 arranged along a first direction F1, the water pipe 41 and the heat exchange pipe 6 are respectively installed between the first heat-conducting block 51 and the second heat-conducting block 52, and the two ends of the slot 75 along the first direction F1 are a slot and a slot bottom wall 752, respectively. The heat-conducting structure 5 is installed on the mounting bracket 7 through a second fastener, and the second fastener passes through the first heat-conducting block 51 and the second heat-conducting block 52, and is threadedly connected to the slot bottom wall 752.

[0093] For example, referring to Figures 5 and 8, the heat-conducting structure 5 includes a first heat-conducting block 51 and a second heat-conducting block 52. The first heat-conducting block 51 and the second heat-conducting block 52 are arranged along a first direction F1 (i.e., the up and down direction shown in Figure 5). The water pipe 41 and the heat exchange pipe 6 are respectively installed between the first heat-conducting block 51 and the second heat-conducting block 52. The water pipe 41 is used to respectively cooperate with the first heat-conducting block 51 and the second heat-conducting block 52 for heat conduction, and the heat exchange pipe 6 is used to respectively cooperate with the first heat-conducting block 51 and the second heat-conducting block 52 for heat conduction.

[0094] The two ends of the slot 75 along the first direction F1 can be respectively configured as a notch and a slot bottom wall 752. The second heat conducting block 52 and the first heat conducting block 51 are adapted to be sequentially installed in the slot 75 along the first direction F1. The first heat conducting block 51 is provided with a sixth hole 511 extending along the first direction F1, and the second heat conducting block 52 is correspondingly provided with a fifth hole 521 extending along the first direction F1. Furthermore, a threaded hole 7521 is correspondingly provided on the slot bottom wall 752. The second fastener has a threaded structure and is adapted to extend along the first direction F1 to penetrate the fifth hole 521 and the sixth hole 511, respectively. The end of the second fastener can extend into the threaded hole 7521 to be threadedly connected to the slot bottom wall 752, thereby mounting the heat conducting structure 5 on the mounting bracket 7.

[0095] Specifically, the first heat-conducting block 51 is first driven to move along the first direction F1 so that the first heat-conducting block 51 can pass through the slot and be installed on the slot bottom wall 752, and then the second heat-conducting block 52 is driven to move along the first direction F1 so that the second heat-conducting block 52 can pass through the slot and be installed on the first heat-conducting block 51. Then, the second fastener is sequentially passed through the fifth hole 521 and the sixth hole 511 and extended into the threaded hole 7521 to fix the heat-conducting structure 5 in the slot 75.

[0096] Through the above arrangement, the heat-conducting structure 5 can be conveniently installed, and the relative stability between the first heat-conducting block 51 and the second heat-conducting block 52 can be improved, thereby improving the reliability of the heat-conducting structure 5.

[0097] Furthermore, as shown in Figures 5 and 8 , the first direction F1, the second direction, and the third direction can be arranged perpendicular to each other. The heat exchange tube 6 and the water conduit 41 are arranged to extend along the second direction (i.e., the front-to-back direction as shown in Figure 5 ). At least two second fasteners can be provided, with the at least two second fasteners located on either side of the heat-conducting structure 5 along the third direction (i.e., the left-to-right direction as shown in Figure 5 ). The two second fasteners are used to secure the heat-conducting structure 5 on both sides along the third direction. This helps improve the installation stability of the heat-conducting structure 5.

[0098] In some embodiments of the present application, a socket 76 is provided on the mounting bracket 7, and the spray head 42 includes a mating section 421 and a nozzle section 422 arranged in sequence along the axial direction. The mating section 421 is plugged into the socket 76, and the nozzle section 422 extends out of the socket 76. The mating section 421 matches the cross-sectional shape of the socket 76 and is a non-circular shape.

[0099] For example, as shown in Figures 5 and 9 , a socket 76 can be provided on the mounting bracket 7, and the socket 76 is arranged corresponding to the through-hole 112 of the panel 111. The spray head 42 includes a mating section 421 and a nozzle section 422, which are arranged in sequence along the axial direction. The mating section 421 is arranged to match the socket 76 so that the mating section 421 can be inserted into the socket 76. The nozzle section 422 is connected to the end of the mating section 421 away from the water conduit 41 and is adapted to extend out of the socket 76.

[0100] The cross-sections of the mating section 421 and the insertion hole 76 match and are non-circular. For example, the cross-section of the mating section 421 can be configured as a polygon, an ellipse, or the like, so that the slot 75 can circumferentially limit the mating section 421 to prevent the mating section 421 from rotating within the slot 75. Preferably, the cross-section of the mating section 421 can be configured as a hexagon, thereby improving the stability of the spray head 42.

[0101] In some embodiments of the present application, the mounting bracket 7 includes a first frame plate 71, which has an avoidance hole 711 corresponding to the socket 76, the aperture of the avoidance hole 711 is smaller than the aperture of the socket 76, the mating section 421 is suitable for inserting into the socket 76 from the end of the socket 76 away from the avoidance hole 711, the nozzle section 422 is passed through the avoidance hole 711 and partially extends to the side of the avoidance hole 711 away from the socket 76, and the first frame plate 71 stops the mating section 421 from moving toward the avoidance hole 711.

[0102] For example, referring to Figures 5 and 9, the mounting bracket 7 includes a first frame plate 71, which is located on the side of the mounting bracket 7 close to the panel 111. The first frame plate 71 has an avoidance hole 711, which is correspondingly arranged and connected to the insertion hole 76. The aperture of the avoidance hole 711 is smaller than the aperture of the insertion hole 76, so that the portion of the first frame plate 71 surrounding the avoidance hole 711 can form a limiting surface.

[0103] The mating section 421 is matched with the socket 76, and the mating section 421 is suitable for being inserted into the socket 76 from the end of the socket 76 away from the avoidance hole 711. The nozzle section 422 is matched with the avoidance hole 711, and the nozzle section 422 can be passed through the avoidance hole 711, and a part of the nozzle section 422 can extend to the side of the avoidance hole 711 away from the socket 76, so that the nozzle section 422 can spray mist toward the outside of the mounting bracket 7 (which is also the outside of the panel 111).

[0104] The end of the mating section 421 facing the nozzle section 422 can be arranged to abut against the limiting surface of the first frame plate 71, so that the first frame plate 71 can limit the mating section 421 and restrict the mating section 421 from moving toward the avoidance hole 711. This can improve the axial installation stability of the spray head 42 and enhance the reliability of the spray head 42.

[0105] In some embodiments of the present application, the heat conducting structure 5 has a first pipe passage 53 for passing the water pipe 41 . The first pipe passage 53 is interference fit with the water pipe 41 to limit the movement of the mating section 421 away from the avoidance hole 711 .

[0106] For example, as shown in Figures 5 and 9 , the heat-conducting structure 5 is mounted on the mounting bracket 7 and includes a first pipe passage 53 therein. The first pipe passage 53 is configured to mate with the water pipe 41. The water pipe 41 is adapted to pass through the first pipe passage 53 and to form an interference fit therewith. This allows the heat-conducting structure 5 to limit the position of the water pipe 41 to prevent axial movement of the water pipe 41, particularly limiting movement of the mating section 421 caused by the water pipe 41 in a direction away from the avoidance hole 711. This arrangement improves the axial installation stability of the spray head 42 and enhances the reliability of the spray head 42.

[0107] For example, the water pipe 41 can be a hard pipe, and the water pump pipeline 8 can be a soft pipe, so as to facilitate the extension of the water pump pipeline 8 and facilitate the interference fit between the first pipe channel 53 and the water pipe 41. Alternatively, the water pump pipeline 8 can also be set as a hard pipe.

[0108] In some embodiments of the present application, the air conditioner 100 includes an outdoor unit part 1 suitable for being located on the outdoor side, and an indoor unit part 2 suitable for being located on the indoor side. The outdoor unit part 1 includes an outdoor heat exchanger 16, a compressor 15 and a four-way valve 18. The indoor unit part 2 includes an indoor heat exchanger. The inlet and outlet of the compressor 15 are respectively connected to two valve ports of the four-way valve 18. The other two valve ports of the four-way valve 18 are respectively connected to the outdoor heat exchanger 16 and the indoor heat exchanger. A part of the refrigerant pipe section connected between the four-way valve 18 and the indoor heat exchanger is used as a heat exchange pipe 6.

[0109] For example, as shown in FIG7 , an air conditioner 100 includes an outdoor unit 1 and an indoor unit 2. The outdoor unit 1 is located on the outdoor side of a wall, while the indoor unit 2 is located on the indoor side of the wall. The outdoor unit 1 includes an outdoor heat exchanger 16, a compressor 15, and a four-way valve 18. The indoor unit 2 includes an indoor heat exchanger. The inlet and outlet of the compressor 15 are connected to two valve ports of the four-way valve 18. The other two valve ports of the four-way valve 18 are connected to the outdoor heat exchanger 16 and the indoor heat exchanger, respectively. The outdoor heat exchanger 16 and the indoor heat exchanger are in communication.

[0110] Specifically, when the air conditioner 100 is in heating mode, the four-way valve 18 can connect the inlet of the compressor 15 with the outdoor heat exchanger 16, and connect the outlet of the compressor 15 with the indoor heat exchanger. After the compressor 15 is running, the compressor 15 can compress the refrigerant, and the compressed refrigerant can flow into the indoor heat exchanger to release heat. The refrigerant after releasing heat flows into the outdoor heat exchanger 16 to absorb heat. The refrigerant after absorbing heat can flow through the four-way valve 18 to flow into the compressor 15; and when the air conditioner 100 is in cooling mode, the four-way valve 18 can connect the outlet of the compressor 15 with the outdoor heat exchanger 16, and connect the inlet of the compressor 15 with the indoor heat exchanger. After the compressor 15 is running, the compressor 15 can compress the refrigerant, and the compressed refrigerant can flow into the outdoor heat exchanger 16 to release heat. The refrigerant after releasing heat flows into the indoor heat exchanger to absorb heat. The refrigerant after absorbing heat can flow through the four-way valve 18 to flow into the compressor 15.

[0111] The portion of the refrigerant pipe connecting the four-way valve 18 and the indoor heat exchanger can be used as heat exchange pipe 6. In this way, in heating mode, as the compressed refrigerant flows from the compressor 15 through the four-way valve 18 to the indoor heat exchanger, it can exchange heat with the heat-conducting structure 5, heating the water pipe 41. At this time, the heat exchange pipe 6 is at a high temperature, providing sufficient heat to fully heat the water pipe 41. This effectively prevents the water pipe 41 from freezing.

[0112] In some embodiments of the present application, the air conditioner 100 is a window-type air conditioner 100. Specifically, as shown in FIG7 , the window-type air conditioner includes an indoor unit 2, an outdoor unit 1, and a connecting portion 3. The indoor unit 2 is located indoors, and the outdoor unit 1 is located outdoors. The connecting portion 3 is used to connect the indoor unit 2 and the outdoor unit 1. The outdoor unit 1 and the connecting portion 3 are rotatably connected about a pivot axis. After installation, the window-type air conditioner 100 generally takes on a saddle shape, allowing it to be mounted astride a wall. This improves the ease of installation of the air conditioner 100.
