[0041] Figure 1 A schematic structural diagram of an evaporator support according to an embodiment of the present invention is shown in FIG. Figure 1 As shown, and reference Figure 2-7 The utility model provides an evaporator support 200 for an air conditioner, including a lower support 220. A mounting space 400 for the evaporator 300 of the air conditioner 100 is formed above the lower support 220. The lower support 220 includes a bottom plate 221 and first water retaining ribs 223 protruding upward from the edges of the bottom plate 221.

[0042] The bottom plate 221 is provided with a first drainage hole 222. On a horizontal projection plane, a minimum distance L between the evaporator 300 and the first water retaining rib 223 is greater than or equal to 10 mm.

[0043] The air conditioner 100 can be a cabinet-type air conditioner, a wall-mounted air conditioner, an integrated air conditioner, etc. In the embodiment of the present invention, the cabinet-type air conditioner is taken as an example to illustrate the technical solution of the present application.

[0044] A cabinet air conditioner usually has a vertically arranged evaporator 300, and the evaporator 300 is fixedly installed in the installation space 400 formed by the evaporator bracket 200. When the evaporator 300 is working, the surface temperature is low, and condensed water is easily condensed. Condensed water usually slides down along the surface of the evaporator 300 and enters the water collection tray below. However, during the manufacturing, assembly, and home installation procedures of the air conditioner 100, the evaporator 300 may be tilted to a certain extent. When the air conditioner 100 is working, the condensed water on the surface of the evaporator 300 may drip directly downwards; in severe cases, the condensed water may drip onto the outside of the water collection tray, causing the condensed water to leak out, affecting the user experience.

[0045] In this embodiment, the bottom plate 221, the first water retaining rib 223, and the first drainage hole 222 can be integrally formed. The bottom plate 221 forms the bottom of the evaporator 300. The bottom plate 221 can be a horizontal or slightly inclined plane, or a stepped surface. Generally, the first drainage hole 222 is located at the lowest point of the bottom plate 221 and drains the condensed water to a predetermined location via a drain pipe.

[0046] The first water retaining ribs 223 surround the edges of the bottom plate 221, forming a water reservoir together with the bottom plate 221. In other words, the lower bracket 220 not only supports and mounts the evaporator 300, but also collects and holds condensed water flowing down from the evaporator 300. Compared to installing an additional water tray on the underside of the evaporator bracket 200, this solution can reduce manufacturing costs.

[0047] On a horizontal projection plane, the minimum distance L between the evaporator 300 and the first water retaining rib 223 is greater than or equal to 10 mm, thereby forming a wide water reservoir between the edge of the evaporator 300 and the first water retaining rib 223. Even if the evaporator 300 is tilted at any angle, causing condensed water to drip directly from the surface of the evaporator 300, it will fall into the water reservoir and will not leak out, thereby improving the user experience.

[0048] It should be understood that the height of the evaporator 300 is an important factor in determining the minimum spacing L. When the evaporator 300 is taller, L can be appropriately increased, for example, to 15 mm, to ensure that condensed water on the top surface of the evaporator 300 drips into the water tank below.

[0049] In some embodiments of the evaporator bracket of the present invention, as Figure 4-5 As shown, the first water retaining rib 223 includes a second water retaining rib 223 a , and the second water retaining rib 223 a is located on a side of the air inlet surface 310 of the evaporator 300 away from the air outlet surface 320 .

[0050] The top end of the second water retaining rib 223 a is higher than the bottom end of the evaporator 300 .

[0051] On the horizontal projection plane, the minimum distance L between the evaporator 300 and the second water retaining rib 223a is greater than or equal to 15 mm.

[0052] Typically, the air inlet surface 310 of the evaporator 300 is located near the air inlet of the air conditioner 100 housing, while the air outlet surface 320 is located near the fan and air outlet duct of the air conditioner 100. A corresponding water tray is provided below the fan and air outlet duct to collect condensed water from the fan and air outlet duct. If condensed water drips from the air inlet surface 310 of the evaporator 300, it may leak out of the air conditioner 100 through the air inlet.

[0053] In this embodiment, the second water retaining rib 223a is located outside the air inlet surface 310 of the evaporator 300. By appropriately increasing the minimum distance between the air inlet surface 310 of the evaporator 300 and the second water retaining rib 223a, when the evaporator 300 is tilted toward the air inlet surface 310, condensed water on the surface of the air inlet surface 310 can smoothly drip into the inside of the second water retaining rib 223a, thereby preventing the condensed water from leaking out.

[0054] In this embodiment, the top of the second water retaining rib 223a is higher than the bottom of the evaporator 300. On the one hand, the second water retaining rib 223a can block the incoming air flow, preventing the incoming air flow from directly passing through the bottom of the evaporator 300, resulting in insufficient heat exchange. On the other hand, it ensures that when the evaporator 300 is tilted at any angle, the bottom of the air inlet surface 310 is always inside the second water retaining rib 223a on the horizontal projection plane, preventing condensed water from leaking out. On the other hand, it can effectively block the splashing of condensed water when dripping from a high place, preventing water droplets from flying out of the air inlet.

[0055] In some embodiments of the evaporator bracket of the present invention, as Figure 4-5 As shown, the first water retaining rib 223 further includes a third water retaining rib 223 b , and the third water retaining rib 223 b is located on the side of the wind outlet surface 320 away from the wind inlet surface 310 .

[0056] The top end of the third water retaining rib 223 b is lower than the bottom end of the evaporator 300 .

[0057] In this embodiment, the third water retaining rib 223 b is located outside the air outlet surface 320 of the evaporator 300 and is used to receive condensed water dripping downward from the surface of the air outlet surface 320 .

[0058] The top end of the third water retaining rib 223 b is lower than the bottom end of the evaporator 300 , so that the heat exchange airflow near the bottom of the evaporator 300 can flow out smoothly from the air outlet surface 320 .

[0059] It should be understood that the air outlet surface 320 of the evaporator 300 is typically located near the fan and the air outlet duct. Corresponding water trays are provided below the fan and the air outlet duct to collect condensed water from the fan and the air outlet duct. In this embodiment, by providing a lower third water retaining rib 223b, space is created for the installation of the fan, the air outlet duct, and other structures. This allows condensed water to be blown into the water tray of the fan and the air outlet duct along the direction of airflow without leaking out of the air conditioner 100.

[0060] In some embodiments of the evaporator bracket of the present invention, as Figure 5 and Figure 7 As shown, a support rib 224 extending along the width of the evaporator 300 is provided on the bottom plate 221 . The support rib 224 is located between the first water retaining rib 223 and the second water retaining rib 223 a . The evaporator 300 is fixedly mounted on the support rib 224 .

[0061] The top of the supporting rib 224 is lower than the top of the second water retaining rib 223 a and higher than the top of the third water retaining rib 223 b .

[0062] In this embodiment, the support ribs 224 are used to support and fix the bottom end of the evaporator 300. The width direction of the evaporator 300 can be V-shaped, U-shaped, etc., and the extension direction of the support ribs 224 is designed to follow the width direction of the evaporator 300.

[0063] The support ribs 224 can also provide heat insulation between the bottom plate 221 and the evaporator 300 , preventing the cold energy of the evaporator 300 from being transferred to the bottom plate 221 , and preventing condensed water from forming on the outside of the bottom plate 221 and leaking out of the air conditioner 100 .

[0064] The top of the support rib 224 is lower than the second water retaining rib 223a and higher than the third water retaining rib 223b, so that the bottom end of the evaporator 300 is lower than the second water retaining rib 223a and higher than the third water retaining rib 223b, preventing the condensed water on the air inlet surface 310 of the evaporator 300 from leaking from the air inlet.

[0065] In some embodiments of the evaporator bracket of the present invention, as Figure 7 As shown, a plurality of first drainage openings 225 are provided on the support rib 224 .

[0066] In this embodiment, by setting up multiple first drainage outlets 225, the water tank formed between the second water retaining rib 223a and the supporting rib 224 and the water tank formed between the supporting rib 224 and the third water retaining rib 223b can be connected, so that the condensed water in the lower bracket 220 can be discharged from the first drainage hole 222.

[0067] In some embodiments of the evaporator bracket of the present invention, as Figure 5 As shown, the height H of the support rib 224 is greater than or equal to 20 mm.

[0068] In this embodiment, the support ribs 224 are relatively high. This, on the one hand, effectively prevents the cooling energy of the evaporator 300 from being transferred to the bottom plate 221 along the support ribs 224, thereby preventing condensation from forming on the outside of the bottom plate 221 and leaking out of the air conditioner 100. On the other hand, it increases the distance between the bottom end of the evaporator 300 and the bottom plate 221, thereby preventing the cooling energy of the evaporator 300 from being transferred to the bottom plate 221 by convection or radiation, further preventing condensation from forming on the outside of the bottom plate 221 and leaking out of the air conditioner 100.

[0069] In some embodiments of the evaporator bracket of the present invention, as Figure 5 and Figure 7 As shown, an upwardly protruding electric heating mounting post 226 is provided on the bottom plate 221, and an upwardly opening mounting blind hole 227 is provided in the electric heating mounting post 226. A second drain port 228 is provided on a hole wall of the mounting blind hole 227 facing the first drain hole 222.

[0070] An electric heater (not shown) is used to assist heating or defrost the evaporator 300. The electric heater is typically a long, vertical rod, with its lower end inserted into the blind mounting hole 227 of the electric heater mounting post 226 and its upper end fixedly connected to the upper bracket 240. When the electric heater is not operating, condensation forms on its surface due to the heat exchange airflow. This condensation then slides down the heater into the blind mounting hole 227.

[0071] If left untreated, condensed water will remain in the blind mounting hole 227 for a long time, becoming moldy and potentially causing the electric heater to rust. In this embodiment, a second drain port 228 is provided on the side of the blind mounting hole 227 facing the first drain hole 222, allowing condensed water to drain smoothly from the blind mounting hole 227 and preventing it from remaining there. The second drain port 228 has a simple structure and does not increase manufacturing costs.

[0072] In some embodiments of the evaporator bracket of the present invention, as Figure 1-2 As shown, the evaporator support 200 further includes an upper support 240 spaced apart from the upper side of the lower support 220, and a fixing column 260 connected between the upper support 240 and the lower support 220. An installation space 400 is formed between the upper support 240 and the lower support 220.

[0073] The lower bracket 220 , the upper bracket 240 and the fixing column 260 are integrally formed.

[0074] In this embodiment, the upper bracket 240, the lower bracket 220, and the fixing column 260 can provide reliable support for the evaporator 300. The evaporator 300 is fixedly installed between the upper bracket 240 and the lower bracket 220, with the upper end of the evaporator 300 connected to the lower side of the upper bracket 240 and the lower end of the evaporator 300 connected to the upper side of the lower bracket 220.

[0075] Two fixing columns 260 may be provided, one at each of the two transverse ends of the evaporator 300, to securely fix the evaporator 300. A connecting rib may be provided between the two fixing columns 260 to improve the structural strength of the fixing columns 260.

[0076] In some embodiments of the evaporator bracket of the present invention, as Figure 2 and Figure 6 As shown, the upper bracket 240 includes a cover plate 241 and a fourth water retaining rib 242 protruding upward from the four edges of the cover plate 241 to form a water collecting trough 244 in the fourth water retaining rib 242 .

[0077] The cover plate 241 is provided with a plurality of second drainage holes 243 . On a horizontal projection plane, all the second drainage holes 243 are located inside the evaporator 300 .

[0078] The upper bracket 240 is close to and in contact with the evaporator 300, and has a lower temperature, which makes it easy for condensed water to condense. In this embodiment, a water collecting trough 244 is provided on the upper side of the cover plate 241 to prevent condensed water from dripping from the edge of the cover plate 241. The second drainage hole 243 is located directly above the evaporator 300, so that when the condensed water in the water collecting trough 244 flows downward, it first drips onto the evaporator 300 and then slides along the surface of the evaporator 300. On the one hand, it can prevent the condensed water from splashing when it drips directly from the cover plate 241 onto the bottom plate 221. On the other hand, when the condensed water slides along the surface of the evaporator 300, the evaporator 300 can be cleaned to prevent dust and the like from adhering to the surface of the evaporator 300 and affecting the heat exchange efficiency of the evaporator 300.

[0079] In some embodiments of the evaporator bracket of the present invention, as Figure 6 As shown, a plurality of fifth water retaining ribs 245 are further provided on the upper bracket 240 to divide the water collecting trough 244 into a plurality of sub-water troughs 244a.

[0080] The top of the fifth water retaining rib 245 is lower than the top of the fourth water retaining rib 242. At least one second drainage hole 243 is provided in each sub-water trough 244a, and the second drainage hole 243 should be provided at the lowest point of the corresponding sub-water trough 244a.

[0081] In this embodiment, the fifth water retaining rib 245 divides the water collection trough 244 into multiple sub-troughs 244a, and a second drainage hole 243 is provided in each sub-trough 244a. The multiple sub-troughs 244a can separate the condensed water on the upper surface of the cover plate 241, preventing the condensed water from all flowing out of a single second drainage hole 243 and causing splashing due to excessive water volume. Furthermore, by distributing the second drainage holes 243, the condensed water drips onto the evaporator 300 from multiple areas, shallowly cleaning multiple surfaces of the evaporator 300 and preventing dust and the like from adhering to the surface of the evaporator 300 and affecting the heat exchange efficiency of the evaporator 300.

[0082] In this embodiment, the top of the fifth water retaining rib 245 is lower than the fourth water retaining rib 242, so that when there is a lot of condensed water in the sub-water tank 244a, the condensed water can overflow to other sub-water tanks 244a to prevent the condensed water from being retained in a sub-water tank 244a.

[0083] In some embodiments of the air conditioner 100 of the present invention, the air conditioner 100 includes an evaporator 300 and an evaporator bracket 200 of any one of the above embodiments or a combination of the embodiments, and the evaporator 300 is vertically installed in the evaporator bracket 200 .

[0084] The evaporator bracket 200 of the air conditioner 100 is tilted at any angle, causing condensed water to drip directly from the surface of the evaporator 300. The condensed water will fall into the water tank and will not leak out, thereby improving the user experience.

[0085] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention can be directly determined or deduced from the contents disclosed herein without departing from the spirit and scope of the present invention.
