[0028] In order to make the objectives, technical solutions and advantages of the present application clearer, the following part will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0032] The HVAC system covers many types of equipment, such as air conditioners, multi-split units, heat pumps, water heaters, etc., and the HVAC system includes indoor units and outdoor units. The indoor unit, especially the ceiling unit, has a heat exchanger of evaporator, condenser, etc. When in cooling mode, the heat exchanger can be an evaporator. At this time, the evaporator absorbs external heat and produces condensed water. Therefore, a water tray is set indoors to receive the condensed water to prevent the condensed water from dripping onto the electrical components of the indoor unit or the indoor installation environment.

[0033] In the related art, the water tray of the indoor unit is usually a composite structure design combining a water holding structure and a heat preservation structure. The water holding structure is used to receive condensed water, and the heat preservation structure is used to prevent condensation on the outside of the water tray. In addition, many other parts are arranged above the water tray in the indoor unit, such as a water pump for extracting condensed water, pipes connected to the evaporator, valve devices, etc. These parts and the water tray are arranged in the height direction of the indoor unit, so the thickness of the indoor unit is relatively large, which is not conducive to the ultra-thin design of the indoor unit, and the application scenarios of the indoor unit are limited.

[0034] To solve the above problems, please refer to Figures 1 to 3 There are many types of air conditioner indoor units 2, such as wall-mounted indoor units, duct-mounted indoor units, ceiling-mounted indoor units, etc. The air conditioner indoor unit 2 of the present application takes a ceiling-mounted indoor unit as an example, and includes a housing 40, a heat exchanger 60, a water pump 50, and an air conditioner water tray 1.

[0035] The shell 40 is formed with an air duct, the heat exchanger 60 and the air conditioner water receiving pan 1 are arranged in the air duct, and the air conditioner water receiving pan 1 is located below the heat exchanger 60, and the water pump 50 is arranged in the water receiving groove 112 of the air conditioner water receiving pan 1 for discharging condensed water. It can be understood that the air conditioner water receiving pan 1 is connected to the shell 40 and is located below the shell 40, and the air conditioner water receiving pan 1 is arranged below the heat exchanger 60, so that the condensed water dripping from the heat exchanger 60 due to gravity can be better received. The casing can be an integrally formed structure to improve the overall strength of the shell 40. The shell 40 can be made of a high-strength material such as stainless steel and aluminum alloy to better protect the various functional components arranged inside the shell 40, and the present application does not limit this.

[0036] Furthermore, the housing 40 of the present application may also include a panel (not shown), which is connected to the bottom of the housing 40 and is located below the air conditioner water tray 1. When the air conditioner indoor unit 2 is a ceiling unit, in an indoor installation environment, a mounting opening is provided on the ceiling, and the panel is sealed at the mounting opening. The panel and the housing cooperate to define an air duct, and the panel is provided with a return air port and an air supply port connected to the air duct.

[0037] In one embodiment, if Figures 4 to 5The air conditioner water receiving pan 1 shown includes a pan body 10 and a heat preservation component 20; the pan body 10 is formed with a water receiving groove 112 for receiving condensed water generated by the evaporator, and the heat preservation component 20 is connected to and covered on the surface of the pan body 10 facing away from the water receiving groove 112; wherein the pan body 10 is formed with a recess 113 that is recessed toward the heat preservation component 20, and the recess 113 is used to avoid the functional components arranged above the pan body 10 in the air conditioner, and the heat preservation component 20 is provided with an avoidance groove 21 for avoiding the recess 113. wherein the pan body 10 in the air conditioner water receiving pan 1 is formed with the above-mentioned recess 113 at least at one position corresponding to the water pump 50 and the pipe connected to the heat exchanger 60.

[0038] Based on the air-conditioning water receiving pan 1 of the embodiment of the present application, a pan body 10 and a thermal insulation component 20 are provided, and a water receiving groove 112 is formed in the pan body 10, and then the thermal insulation component 20 is coated on the surface of the pan body 10 facing away from the water receiving groove 112, so that the water receiving groove 112 can be used to receive condensed water generated by the evaporator. The coating of the thermal insulation component 20 prevents condensation from occurring on the outside of the air-conditioning water receiving pan 1 due to the low temperature of the air in contact with the air. Furthermore, by forming a recess 113 sunken toward the thermal insulation component 20 on the disk body 10, the recess 113 can be used to avoid functional components arranged above the disk body 10 in the air conditioner, and the recess 113 also increases the capacity of the water receiving tank 112 to accommodate condensed water, and the thermal insulation component 20 is also provided with an avoidance groove 21 for avoiding the recess 113. In this way, the functional components in the air-conditioning indoor unit can be installed downward in the thickness direction using the recess 113 area, which reduces the thickness of the air-conditioning indoor unit 1, which is conducive to realizing the ultra-thin design of the air-conditioning indoor unit 2. It can be understood that the air-conditioning indoor unit 2 with an ultra-thin design can be suitable for installation environments with a larger installation space, and can also be suitable for installation environments with limited installation space. It can be seen that the solution of the present application expands the application scenarios of the air-conditioning indoor unit 2. In order to achieve the above-mentioned effects and at the same time ensure the heat insulation effect of the avoidance groove 21, optionally, the avoidance groove 21 blocks the heat transfer from the disk to the insulation component 23 through the air medium, or the avoidance groove 21 is filled with heat insulation materials, such as cotton cloth, foam and other materials, which is not limited in the present application.

[0039] It is understandable that the water receiving groove 112 is arranged below the heat exchanger 60 to receive the condensed water condensed on the surface of the heat exchanger 60. The heat exchanger 60 also has a guiding structure for guiding the condensed water to flow into the water receiving groove 112. Such a configuration improves the water receiving efficiency of the water receiving groove 112.

[0040] The functional components may be a water pump 50, piping, etc., wherein the water pump 50 is provided with a bracket, and is fixedly connected to the housing 40 of the air-conditioning indoor unit 2 through the bracket, so that the water pump 50 is installed inside the housing 40. The water pump 50 also has a water inlet and a water outlet, the water inlet is connected to the air-conditioning water receiving pan 1, and the water outlet can be connected to the water delivery pipeline outside the air-conditioning indoor unit 2. In addition, the water pump 50 is also connected to a float (not shown), and the float part extends into the water receiving tank 112 to detect the condensed water level in the water receiving tank 112 to avoid overflow caused by excessive accumulation of condensed water. Thus, the condensed water gathered in the air-conditioning water receiving pan 1 can be transported to the outside of the air-conditioning indoor unit 2 by the water pump 50, so that the condensed water in the air-conditioning water receiving pan 1 can be discharged in time to avoid overflow of condensed water.

[0041] Of course, when the functional component is a pipe, the pipe is arranged above the panel body 11 and partially extends into the water receiving groove 112, that is, the recess 113 can also provide corresponding avoidance space for the pipe. The water pump 50 and the pipe and other functional components occupy a certain position inside the housing 40, and the recess 113 can avoid the space occupied by the water pump 50, thereby achieving the thinning of the overall body of the air conditioner indoor unit 2.

[0042] Please refer again Figure 4 and Figure 5 In one embodiment, the heat preservation component 20 includes a foam member 22 and a heat insulating member 23; the foam member 22 is connected to and covers the surface of the tray body 10 facing away from the water receiving groove 112, and the foam member 22 is provided with an avoidance through hole at the position corresponding to the concave portion 113; the heat insulating member 23 is connected to the foam member 22 and covers the opening of the avoidance through hole away from the tray body 10, so as to cooperate with the foam member 22 to form the avoidance groove 21. In this embodiment, the heat preservation component 20 reduces the heat exchange efficiency between the condensed water in the water receiving groove 112 and the external environment by providing the foam member 22 covering the back of the tray body 10, thereby avoiding the formation of condensation on the outside of the water receiving tray. And by providing the avoidance through hole for the concave portion 113, on the one hand, the concave portion 113 can be accommodated by the avoidance through hole, reducing the thickness of the concave portion 113, and on the other hand, the heat exchange efficiency between the condensed water in the concave portion 113 and the external environment is reduced, thereby achieving the balance between preventing condensation and reducing the thickness of the fuselage. Furthermore, the present embodiment also provides a heat insulating member 23, which is connected to the foam member 22 and covers the opening of the avoidance hole away from the disc body 10, so that the foam member 22 cooperates to form the avoidance groove 21, thereby making the fuselage flat and ensuring the thinness of the fuselage.

[0043] Specifically, there is a gap between the lower surface of the recess 113 and the heat insulating member 23. By setting the gap, the heat transfer efficiency of the condensed water is reduced, the condensation on the outside of the fuselage is reduced, and the foaming member 22 is reduced, which reduces the cost, and also ensures that the thickness of the fuselage at the recess 113 is small to the greatest extent, taking into account the effects of preventing condensation and reducing the thickness of the fuselage.

[0044] Optionally, the spacing between the lower surface of the recess 113 and the heat insulating member 23 is 2-6 mm. This arrangement, on the one hand, allows the recess 113 to have enough space to avoid the functional components of the air conditioner and can increase the capacity of the water tank 112. On the other hand, it ensures that the structure of the tray 10 is moderate and the body is smooth, so that the thickness of the body is moderate, and ensures that the thickness of the heat insulating member 23 meets the basic requirements of heat preservation and heat insulation. It can be understood that when the spacing between the lower surface of the recess 113 and the heat insulating member 23 is less than 2 mm, the thickness of the heat insulating member 23 needs to be reduced accordingly, and the heat preservation and heat insulation effect will be further reduced; when the spacing between the lower surface of the recess 113 and the heat insulating member 23 is greater than 6 mm, the overall thickness of the tray 10 will increase, and it is difficult to meet the ultra-thin requirements of the body. Therefore, the spacing between the recess 113 and the heat insulating member 23 is also selected to be 2 mm, 3 mm, 4 mm, 5 mm or 6 mm, etc., which can achieve the above-mentioned effect.

[0045] like Figure 1 As shown, in one embodiment, when the tray body 10 is formed into an L-shaped structure, the foam member 22 covers the entire lower surface of the tray body 10 to insulate the lower surface of the tray body 10 as a whole and ensure the heat insulation effect. The heat insulation member 23 can be selected to cover the short side of the L-shaped structure of the tray body 10, that is, the side of the tray body 10 formed with the avoidance groove 21. At this time, the heat insulation member 23 covers part of the lower surface of the foam member 22, and the heat insulation member 23 at least covers the avoidance through hole 221. While ensuring the heat insulation effect of the heat insulation member 23, it can reduce material consumption, thereby saving costs, and can further reduce a part of the thickness of the air conditioner water receiving tray 1. It can be understood that the heat insulation member 23 can also cover the entire lower surface of the foam member 22 to better improve the heat insulation effect of the heat insulation member 23. The extension direction of the heat insulation member 23 is consistent with the extension direction of the bottom wall of the water receiving groove 112, thereby greatly reducing the heat exchange efficiency of the heat exchange surface between the water receiving groove 112 and the external environment, and further preventing condensation from occurring on the outside of the fuselage.

[0046] Specifically, the heat insulating member 23 includes a plastic layer connected to the lower surface of the foam member 22. The plastic layer has the characteristics of good insulation, strong waterproofness, low thermal conductivity, general formability, good colorability, and low processing cost, so it can achieve a good insulation effect, reduce the heat exchange efficiency between the condensed water in the water tank 112 and the external environment, and prevent condensation. The material of the plastic layer can be selected as EVA material, of course, it can also be other materials that can achieve the above effect, and this application does not limit this.

[0047] The heat insulating member 23 further includes a flannel layer connected to the lower surface of the plastic layer. The flannel layer has certain flexibility and low thermal conductivity, and can further provide a heat insulating effect when attached to the plastic layer, greatly reducing the heat exchange efficiency between the condensed water in the water receiving tank 112 and the external environment, and preventing condensation.

[0048] Please refer again Figure 3 In one embodiment, the tray body 10 includes a tray body 11 and a side plate 12, the tray body 11 defines a water receiving groove 112 and forms a recess 113, and the side plate 12 extends outward from the periphery of the tray body 11; the foam member 22 is arranged around the outside of the tray body 11, and the upper end of the foam member 22 is fixedly connected to the side plate 12, wherein a heat insulation cavity 30 is formed between the foam member 22 and the tray body 11. In this embodiment, the tray body 10 is configured in a manner that the tray body 11 and the side plate 12 are connected, so that the shape of the tray body 10 is more suitable for the structure of the air conditioner, and the water receiving groove 112 and the recess 113 are defined by the tray body 11, thereby ensuring the stability of the air conditioner structure. In addition, the heat insulation cavity 30 is formed between the foam member 22 and the tray body 11, which reduces the heat exchange efficiency between the condensed water and the foam member 22, and prevents condensation on the fuselage. In addition, the heat-insulating cavity 30 is connected to the avoidance groove 21. Such an arrangement increases the heat dissipation area of ​​the heat-insulating cavity 30, further reduces the heat exchange efficiency between the condensed water and the foam part 22, and better prevents condensation on the fuselage.

[0049] The present application also proposes a HVAC system, which includes the air conditioner indoor unit 2 as described above. The specific structure of the air conditioner indoor unit 2 refers to the above embodiment. Since the HVAC system of the present application adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
