[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0039] The following is for reference. Figures 1-15 Description of a water receiving tray assembly 101 according to an embodiment of the present utility model.

[0040] Reference Figures 3-6According to the first aspect of the present invention, the water receiving tray assembly 101 includes: a water receiving tray component 1 and a heating component 2.

[0041] A water receiving tray component 1 has a water receiving groove 11 formed therein. A heating component 2 is installed on the water receiving tray component 1 and includes at least one heating component 21. The heating component 21 includes a heating body 22, and at least a portion of the heating body 22 is located in the water receiving groove 11.

[0042] For example, part of the structure of the water receiving tray component 1 is recessed downward to form a water receiving groove 11; as another example, the water receiving tray component 1 includes a water receiving platform and a water receiving box 153. The water receiving box 153 is located at the bottom of the water receiving platform. The water receiving platform is provided with a water receiving platform hole for allowing water on the water receiving platform to flow into the water receiving box 153. The water receiving box 153 has a water receiving groove 11 formed inside.

[0043] By forming a water receiving trough 11 inside the water receiving tray component 1, water can be concentrated and gathered in the water receiving trough 11, making it convenient to collect and discharge the water in the water receiving tray.

[0044] For example, heating assembly 2 includes one heating element 21; for another example, heating assembly 2 includes two heating elements 21; for yet another example, heating assembly 2 includes three heating elements 21.

[0045] For example, part of the heating component 2 is located inside the water receiving tank 11, and another part of the heating component 2 is located outside the water receiving tank 11; or, for another example, the entire heating component 2 is located inside the water receiving tank 11.

[0046] In related technologies, the heating element 2 is typically located at the bottom of the water receiving tank 11. The heat generated by the heating element 2 needs to be transferred to the body of the water receiving tank 11 first, and then transferred to the water through the water receiving tank 11. This application, by placing at least a portion of the heating element 2 inside the water receiving tank 11, allows the heating element 2 to directly contact the water in the water receiving tank 11. The heat generated by the heating element 2 is directly transferred to the water in the water receiving tank 11, eliminating the need for the heat to be transferred to the body of the water receiving tank 11 first and then to the water in the water receiving tank 11, as is done in related technologies. The heat transfer path is shorter, which can improve the heat transfer efficiency of the heating element 2, reduce energy loss, improve the heating effect of the heating element 2, and more effectively prevent the water in the receiving pan from freezing and expanding at low temperatures, which could then puncture the heat exchanger and cause leakage of the heat exchange medium.

[0047] According to the embodiment of the present invention, the water receiving tray assembly 101 includes a heating component 2, and at least a portion of the heating component 2 is located within the water receiving tank 11. The heating component 2 can directly contact the water in the water receiving tank 11, and the heat generated by the heating component 2 is directly transferred to the water, reducing the heat transfer path, improving the heat transfer efficiency of the heating component 2, improving the heating effect of the heating component 2, and more effectively preventing the water in the water receiving tray from freezing and expanding in volume under low temperature conditions, which would then puncture the heat exchanger and cause leakage of the heat exchange medium.

[0048] According to the embodiment of the present utility model, the water receiving tray assembly 101, by placing at least a portion of the heating component 2 inside the water receiving tank 11, allows the heating component 2 to directly contact the water in the water receiving tank 11. The heat generated by the heating component 2 is directly transferred to the water, reducing the heat transfer path, improving the heat transfer efficiency of the heating component 2, reducing energy loss, and improving the heating effect of the heating component 2 on the water in the water receiving tray.

[0049] Reference Figure 10 According to some embodiments of the present invention, the heating body 22 is elongated, and at least a portion of the heating body 22 extends in a curved manner. For example, a portion of the heating body 22 extends in a straight line, and a portion of the heating body 22 extends in a curved manner.

[0050] By making the heating body 22 into a long strip shape and by bending and extending at least part of the heating body 22, the arrangement density of the heating body 22 in the water receiving tank 11 can be increased, making the heating of the water in the water receiving tank 11 more uniform and sufficient. Reference Figure 10 According to some embodiments of the present invention, the heating body 22 includes a plurality of heating body segments 221 and a heating connecting segment 222. The plurality of heating body segments 221 are arranged side by side, each heating body segment 221 extends along a straight line, and the heating connecting segment 222 extends along an arc. The adjacent ends of two adjacent heating body segments 221 are connected by the heating connecting segment 222.

[0051] For example, refer to Figure 10 , Figure 10 The dashed lines in the figure represent the distribution positions of the heating body 22 in the water receiving tank 11.

[0052] By arranging multiple heating body segments 221 side by side, each extending in a straight line, the heating body 22 can heat the water more thoroughly and evenly along the length of the water tank 11, increasing the density of the heating body 22 within the water tank 11 and improving its heating effect on the water. Furthermore, by connecting adjacent heating body segments 221 at their nearest ends via a heating connection segment 222, the adjacent segments can be joined together to form a single unit, making control of the heating body 22 more convenient.

[0053] Reference Figures 8-10 According to some embodiments of the present invention, the water receiving tank 11 extends in a long strip shape, and multiple heating body segments 221 of each heating component 21 are arranged side by side along the width direction of the water receiving tank 11, with the heating body segments 221 having the same extension direction as the water receiving tank 11.

[0054] By arranging multiple heating body segments 221 of each heating component 21 side by side along the width direction of the water receiving tank 11, the heating body 22 can heat the water more fully and evenly in the width direction of the water receiving tank 11. By aligning the heating body segments 221 with the extension direction of the water receiving tank 11, the heating body 22 can heat the water more fully and evenly in the length direction of the water receiving tank 11, thereby increasing the arrangement density of the heating body 22 in the water receiving tank 11 and improving the heating effect of the heating body 22 on the water in the water receiving tank 11.

[0055] Reference Figures 8-10 According to some embodiments of the present invention, the heating body 22 includes two heating body segments 221. The straight line at the center of each heating body segment 221 along the width direction of the water receiving tank 11 is the center line of the heating body segment 221. The distance between the center lines of the two heating body segments 221 is d1. The width of the water receiving tank 11 is d2. The side wall in the width direction of the water receiving tank 11 is the tank side wall 111. The distance between the center line of the heating body segment 221 and the adjacent tank side wall 111 in the width direction of the water receiving tank 11 is d3, where d1≥1 / 2*d2.

[0056] By including two heating body sections 221 in the heating component 21, the heating component 21 can be connected to the water tank 11 for more thorough heating. At the same time, the length of the heating body 22 can be appropriately reduced to save the amount of heating component 21 used and reduce costs.

[0057] For example, the distance d1 between the center lines of the two heating body sections 221 can be 1 / 2*d2, 3 / 4*d2, 4 / 5*d2, etc.

[0058] For example, refer to Figure 10 , Figure 10 The dashed lines in the diagram represent the distribution of the heating body 22 within the water receiving tank 11.

[0059] By ensuring that the distance d1 between the centerlines of the two heating body sections 221 and the minimum width d2 of the water receiving tank 11 satisfy 1 / 2*d2≤d1, the heating body section 221 can heat the water more fully in the width direction of the water receiving tank 11, and can also avoid damage to the heating component 21 caused by excessive bending of the connecting section.

[0060] Reference Figures 8-10 According to some embodiments of the present invention, the heating body 22 includes two heating body segments 221. The straight line at the center of each heating body segment 221 along the width direction of the water receiving tank 11 is the center line of the heating body segment 221. The distance between the center lines of the two heating body segments 221 is d1. The width of the water receiving tank 11 is d2. The side wall in the width direction of the water receiving tank 11 is the tank side wall 111. The distance between the center line of the heating body segment 221 and the adjacent tank side wall 111 in the width direction of the water receiving tank 11 is d3. Wherein, 1 / 5*d2≤d3≤1 / 4*d2.

[0061] For example, the minimum distance d3 between the centerline of the heating section and the side wall of the water receiving tank 11 in the width direction of the water receiving tank 11 can be 1 / 5*d2, 11 / 50*d2, 1 / 4*d2, etc.

[0062] For example, refer to Figure 10 , Figure 10 The dashed lines in the diagram represent the distribution of the heating body 22 within the water receiving tank 11.

[0063] By ensuring that the minimum distance d3 between the centerline of the heating section and the side wall of the water receiving tank 11 in the width direction of the water receiving tank 11 and the minimum width d2 of the water receiving cavity in the second direction satisfy 1 / 5*d2≤d3≤1 / 4*d2, the heating section can heat the water more fully in the width direction of the water receiving tank 11.

[0064] Reference Figure 6 and Figure 8 According to some embodiments of the present invention, the water receiving tray assembly 101 further includes a fixed bracket 12, which is installed in the water receiving tank 11. The fixed bracket 12 and the inner wall of the water receiving tank 11 together define a receiving cavity 121, which is connected to the water receiving tank 11. At least a portion of the heating body 22 is received in the receiving cavity 121.

[0065] For example, the water receiving tank 11 is long and narrow, and the fixing bracket 12 extends along the length of the water receiving tank 11.

[0066] For example, the heating body 22 is entirely contained within the receiving cavity 121; or, for another example, the heating body 22 includes a heating main body section 221 and a heating connecting section 222, the heating main body section 221 is elongated and extends along the length of the water receiving tank 11, the heating connecting section 222 is connected to the heating main body section 221, and the heating main body section 221 is contained within the receiving cavity 121.

[0067] By including a fixed bracket 12 in the water receiving tray assembly 101 and connecting the fixed bracket 12 to the water receiving tank 11, at least a portion of the heating element 21 is accommodated in the receiving cavity 121. This allows the fixed bracket 12 to fix the heating element 21 relative to the water receiving tank 11, making the heating element 21 more evenly distributed in the water receiving tank 11 and reducing the problem of uneven heating of the heating element 21 to the water receiving tank 11 caused by the movement of the heating element 21 within the water receiving tank 11.

[0068] Reference Figures 8-10 According to some embodiments of the present invention, the heating body 22 is elongated and the fixing bracket 12 is elongated. The width direction of the heating body 22 located in the receiving cavity 121 is consistent with the width direction of the corresponding fixing bracket 12.

[0069] For example, the water receiving tank 11 is elongated, the heating body 22 is elongated, the fixing bracket 12 is elongated, and the width direction of the heating body 22, the width direction of the fixing bracket 12, and the width direction of the water receiving tank 11 are consistent within the receiving cavity 121.

[0070] By aligning the width of the heating body 22 within the receiving cavity 121 with the width of the corresponding fixed bracket 12, the fixed bracket 12 can more effectively constrain the heating body 22, reducing the uneven heating of the heating component 21 within the water receiving tank 11 caused by the movement of the heating component 21 within the water receiving tank 11.

[0071] Reference Figure 6 According to some embodiments of this utility model, the width of the fixed bracket 12 is d5, the width of the heating body 22 is d6, and d6≤d5≤2*d6.

[0072] For example, the width d5 ​​of the fixed bracket 12 can be d6, 1.2*d6, 1.4*d6, 1.5*d6, 1.6*d6, 1.8*d6, 2*d6, etc.

[0073] By ensuring that the width d5 ​​of the fixed bracket 12 and the width d6 of the heating element 21 satisfy d6≤d5, the heating element 21 can be more easily assembled into the receiving cavity 121, reducing the assembly difficulty of the heating element 21. By ensuring that the width d5 ​​of the fixed bracket 12 and the width d6 of the heating element 21 satisfy d5≤2*d6, the fixed bracket 12 can more fully limit the heating element 21 in the width direction of the water receiving tank 11, and the fixing effect of the fixed bracket 12 on the heating element 21 is better.

[0074] Reference Figures 6-8 According to some embodiments of the present invention, the heating body 22 includes a plurality of heating body segments 221 and a heating connecting segment 222. The plurality of heating body segments 221 are arranged side by side, each heating body segment 221 extends in a straight line, and the heating connecting segment 222 extends in an arc. The adjacent ends of two adjacent heating body segments 221 are connected by the heating connecting segment 222. Each heating component 21 is provided with a plurality of fixed brackets 12. The number of fixed brackets 12 provided with each heating component 21 is the same as the number of heating body segments 221 in each heating component 21 and corresponds one-to-one. Each heating body segment 221 is accommodated in the accommodating cavity 121 defined by the corresponding fixed bracket 12.

[0075] For example, refer to Figure 6 There are two fixed brackets 12, which are arranged at intervals along the width direction of the water receiving tank 11; the heating component 21 includes two heating body sections 221, which extend along the length direction of the water receiving tank 11 and are arranged at intervals along the width direction of the water receiving tank 11. The two heating body sections 221 correspond to the two fixed brackets 12 respectively, and each heating body section 221 is accommodated in the receiving cavity 121 of the corresponding fixed bracket 12.

[0076] By including multiple heating body segments 221 in the heating component 21, and extending the heating body segments 221 along the length direction of the water receiving tank 11, and arranging the multiple heating body segments 221 at intervals along the width direction of the water receiving tank 11, the heating component 21 can cover a larger area in the water receiving tank 11, and the heating component 21 can heat the water in the water receiving tank 11 more evenly and fully, resulting in a better heating effect.

[0077] By having multiple fixed supports 12, and ensuring that the number of fixed supports 12 corresponding to each heating component 21 is the same as and corresponds one-to-one with the number of heating body segments 221 in each heating component 21, and that the heating body segments 221 are accommodated in the receiving cavity 121 of the fixed support 12 corresponding to the heating body segments 221, the fixed supports 12 can fix and limit each heating body segment 221, thus more effectively reducing the problem of uneven heating of the heating component 21 to the water tank 11 caused by the movement of the heating component 21 within the water tank 11, and making the fixing and limiting effect of the fixed supports 12 on the heating component 21 more effective.

[0078] Reference Figure 15 According to some embodiments of the present invention, the bottom of the fixed bracket 12 is provided with a water passage hole 122, which connects the receiving cavity 121 and the water receiving tank 11.

[0079] By providing a water passage hole 122 at the bottom of the fixed bracket 12, water in the water tank 11 can enter the receiving cavity 121 through the water passage hole 122, so that the heating component 2 in the receiving cavity 121 heats the water, thereby increasing the contact area between the heating component 2 and the water in the receiving cavity 121 and improving the heating efficiency of the heating component 2.

[0080] By positioning the water inlet 122 at the bottom of the fixed bracket 12, when the water in the water tank 11 is low, water can still flow from the water tank 11 into the receiving cavity 121 through the water inlet 122, so that the heating element 21 in the receiving cavity 121 can fully heat the water.

[0081] Reference Figure 15 According to some embodiments of the present invention, water passage holes 122 are provided on both sides of the width direction of the fixed bracket 12.

[0082] By providing water passage holes 122 on both sides of the width direction of the fixed bracket 12, water on both sides of the width direction of the fixed bracket 12 can enter the receiving cavity 121 through the water passage holes 122, so that the heating component 2 in the receiving cavity 121 heats the water, thereby increasing the contact area between the heating component 2 and the water in the receiving cavity 121 and improving the heating efficiency of the heating component 2.

[0083] Reference Figure 15 According to some embodiments of the present invention, there are multiple water passage holes 122 located on the same side of the width direction of the fixed bracket 12, and the multiple water passage holes 122 are spaced apart along the extension direction of the fixed bracket 12.

[0084] By providing water passage holes 122 at the bottom of the fixed bracket 12, and arranging multiple water passage holes 122 at intervals along the length of the water receiving tank 11, water is allowed to flow into the receiving cavity 121 through the water receiving tank 11. This allows the heating component 21 in the receiving cavity 121 to heat water at different positions along the length of the water receiving tank 11, making the heating of the water by the heating component 21 more uniform.

[0085] Reference Figures 8-10 According to some embodiments of the present invention, the water receiving tank 11 assembly further includes a pressure plate 13, which is located on the upper side of the fixed bracket 12 and abuts against the fixed bracket 12. The pressure plate 13 is used to install and fix the fixed bracket 12 in the water receiving tank 11, and the pressure plate 13 is connected to the water receiving tray component 1.

[0086] By positioning the pressure plate 13 above the fixed bracket 12 and abutting against it, the pressure plate 13 can be fixed relative to the water receiving tank 11, preventing the pressure plate 13 from shifting relative to the water receiving tank 11 and causing the pressure plate 13 to fail in fixing the fixed bracket 12. By positioning the second connecting part of the pressure plate 13 at the top of the fixed bracket 12 and abutting against it in the vertical direction, the second connecting part can limit the vertical movement of the fixed bracket 12. The second connecting part presses down on the fixed bracket 12, preventing the fixed bracket 12 from shifting upward and causing the fixed bracket 12 to fail in fixing the heating element 21.

[0087] For example, the pressure plate 13 includes a first connecting part and a second connecting part. The first connecting part is fixedly connected to the side wall of the water receiving tank 11. The second connecting part is located at the top of the fixed bracket 12 and abuts against the fixed bracket 12 in the vertical direction. The first connecting part and the second connecting part are arranged along the width direction of the water receiving tank 11. The first connecting part extends in the vertical direction and is fixedly connected to the side wall of the water receiving tank 11. The second connecting part is connected to the bottom of the first connecting part and extends in the width direction of the water receiving tank 11.

[0088] Reference Figures 8-10 According to some embodiments of the present invention, the pressure plate 13 and the water receiving tray component 1 are detachably connected.

[0089] For example, the pressure plate 13 is connected to the water receiving tray component 1 by fasteners.

[0090] By connecting the pressure plate 13 to the water receiving tray component 1, the pressure plate 13 not only limits the fixed bracket 12 in the vertical direction, but also limits the fixed bracket 12 in the horizontal direction, thus more effectively preventing the fixed bracket 12 from moving and causing the fixed bracket 12 to fail to fix the heating component 21.

[0091] Reference Figures 8-10According to some embodiments of this utility model, there are multiple pressure plates 13, which are arranged at intervals along the extension direction of the fixed bracket 12. By having multiple pressure plates 13 and arranging them at intervals along the extension direction of the fixed bracket 12, the fixed bracket 12 can be limited by the vertical direction of the pressure plates 13 in the extension direction of the fixed bracket 12, thus more effectively preventing the fixed bracket 12 from moving and causing the fixed bracket 12 to fail to fix the heating component 21.

[0092] Reference Figures 8-10 According to some embodiments of the present invention, the water receiving trough 11 extends in a long strip shape, the extension direction of the fixed bracket 12 is consistent with the extension direction of the water receiving trough 11, the pressure plate 13 extends along the width direction of the water receiving trough 11, the side wall in the width direction of the water receiving trough 11 is the trough side wall 111, and the two ends of the pressure plate 13 in the width direction are respectively connected to the two trough side walls 111 of the water receiving trough 11.

[0093] By connecting the two ends of the pressure plate 13 in the width direction to the two side walls 111 of the water receiving tank 11, the pressure plate 13 can more effectively limit the fixed bracket 12 in the width direction of the water receiving tank 11. Furthermore, when the water receiving tank 11 assembly includes multiple fixed brackets 12, the pressure plate 13 can simultaneously limit the vertical movement of all fixed brackets 12. By connecting the pressure plate 13 to both side walls of the water receiving tank 11 in the width direction, the fixation between the pressure plate 13 and the water receiving tank 11 can be more complete.

[0094] For example, the pressure plate 13 includes two first connecting parts and one second connecting part. The first connecting parts are fixedly connected to the side wall of the water receiving tank 11. The two first connecting parts extend in the vertical direction and are respectively connected to the two side walls of the water receiving tank 11 in the width direction. The second connecting part is connected to the middle of the two first connecting parts in the width direction of the water receiving tank 11. The second connecting part is located at the top of the fixed bracket 12 and abuts against the fixed bracket 12 in the vertical direction.

[0095] For example, the length of the second connecting part along the width direction of the water receiving groove 11 is the same as the width of the water receiving groove 11.

[0096] According to some embodiments of this utility model, the heating body 22 is a flexible component. By making the heating body 22 a flexible component, it can be bent within the water receiving tank 11, making it easier to arrange and install. This eliminates the need for bending processes required for non-flexible heating bodies 22 in related technologies, simplifying the installation process. For example, the heating body 22 extends along the length of the water receiving tank 11 within the tank, and is bent at one end along the length of the tank and then bent back, resulting in more uniform heating of the water in the tank and increased heating effect.

[0097] Reference Figures 12-14 According to some embodiments of this utility model, the heating body 22 is elongated and its cross-section is circular. By making the heating body 22 elongated and its cross-section circular, the heating element can be more easily manufactured.

[0098] Reference Figures 12-14 According to some embodiments of the present invention, the heating body 22 includes a heating core 23 and a first protective layer 231, the first protective layer 231 covering the outside of the heating core 23 and being a thermally conductive and insulating layer. For example, the first protective layer 231 is a silicone rubber layer.

[0099] By including a heating core 23 and a first protective layer 231 in the heating body 22, and by covering the heating core 23 with the first protective layer 231 and being a thermally conductive and insulating layer, the first protective layer 231 can separate the heating core 23 inside the heating element from the water outside, thus insulating the heating core 23 from the outside and preventing the current in the heating core 23 from being transferred to the water, which could lead to leakage and danger.

[0100] Reference Figures 12-14 According to some embodiments of the present invention, the heating body 22 further includes a second protective layer 232, which covers the outside of the first protective layer 231 and is a metal braided layer, and the second protective layer 232 is grounded.

[0101] For example, the material of the second protective layer 232 can be 304 stainless steel.

[0102] By including a second protective layer 232 on the heating body 22, which covers the outside of the first protective layer 231 and is a metal braided layer, and grounding the second protective layer 232, the outermost part of the heating body 22 can be made safer, preventing leakage from the heating body 22 that could transfer current to the water in the water tank 11 and cause a hazard. Furthermore, the metal braided nature of the second protective layer 232 increases the strength of the heating element, preventing it from bending and breaking in the water tank 11.

[0103] For example, when the first protective layer 231 is damaged and relevant personnel need to repair or replace the heating body 22, the relevant personnel should first touch the second protective layer 232 with their hands. Since the second protective layer 232 is grounded, it can prevent the heating body 22 from leaking electricity and causing injury to the relevant personnel.

[0104] Reference Figure 12 According to some embodiments of the present invention, the heating component 21 further includes a connecting wire harness 234, one end of which is connected to the heating core 23, and the connection between the connecting wire harness 234 and the heating core 23 is covered with an insulating end cap 233. The other end of the connecting wire harness 234 is provided with a terminal block 235.

[0105] For example, terminal 235 can be connected to electrical control box 35.

[0106] By covering the connection point between the connecting wire harness 234 and the heating core 23 with an insulating cap 233, the insulating cap 233 can insulate the connection point between the connecting wire harness 234 and the heating core 23 from the water in the water tank 11, reducing leakage current in the heating element 21. By providing a terminal 235 at the other end of the connecting wire harness 234, the heating element 21 is electrically connected through the terminal 235 to generate heat in the heating body 22.

[0107] For example, the side wall of the water tank 11 is provided with a wire hole, and the connecting wire harness 234 passes through the wire hole to connect the heating body 22 in the water tank 11 to the electrical control box 35.

[0108] Reference Figures 12-14 According to some embodiments of the present invention, the heating body 22 further includes a second protective layer 232, which covers the outside of the first protective layer 231 and is a metal braided layer. The heating component 21 further includes a grounding wire 236, one end of which is connected to the second protective layer 232, and the other end of which is provided with a terminal piece 237.

[0109] For example, terminal 237 can be connected to the grounding connection point on the electrical control box 35.

[0110] By making the second protective layer 232 cover the outside of the first protective layer 231 and being a metal braided layer, and by connecting one end of the grounding wire 236 to the second protective layer 232 and providing a terminal piece 237 at the other end of the grounding wire 236, the second protective layer 232 can be grounded. This makes the outermost part of the heating body 22 safer and prevents leakage from the heating body 22 from transferring current to the water in the water tank 11, which could cause a hazard. Furthermore, the fact that the second protective layer 232 is a metal braided layer can increase the strength of the heating element and prevent it from bending and breaking in the water tank 11.

[0111] According to some embodiments of the present invention, the heating assembly 2 includes a plurality of heating elements 21, at least some of which are independently controlled. For example, each heating assembly 2 includes two heating elements 21, and the two heating elements 21 can be independently controlled to start and stop.

[0112] By including multiple heating elements 21 in the heating assembly 2 and controlling at least some of the heating elements 21 independently, the degree of heating of the water tank 11 by the heating elements 21 can be adjusted by adjusting the number of heating elements 21 activated, so as to cope with different temperature scenarios, reduce power consumption and save energy while fully heating the water tank 11.

[0113] According to some embodiments of this utility model, the heating element 21 is an electric heating element 21. By making the heating element 21 an electric heating element 21, the operation of the heating element 21 can be made more convenient.

[0115] For example, a portion of the heating element 21 is located inside the water receiving tank 11, and another portion of the heating element 21 is located inside the drain pipe 14.

[0116] For example, the heating assembly 2 includes a plurality of heating elements 21, wherein at least some of the heating elements 21 are located in the water receiving tank 11 and at least some of the heating elements 21 are located in the drain pipe 14.

[0117] For example, the drain pipe 14 is connected to the drain hole 141 by a thread.

[0118] By including a drain pipe 14 in the water tray assembly 101, the drain pipe 14 can drain the water in the water tank 11, preventing water accumulation in the water tank 11 from overflowing from the water tray assembly 101 and causing dangers such as short circuits. By placing at least a portion of the heating element 21 inside the drain pipe 14, the heating element 21 can heat the water in the drain pipe 14, preventing the water from freezing inside the drain pipe 14 and causing it to crack and be damaged, and also preventing ice from clogging the drain pipe 14 and causing drainage difficulties.

[0119] Reference Figure 11 According to some embodiments of the present invention, in the extending direction of the drain pipe 14, a discharge port is formed at the end of the drain pipe 14 away from the drain hole 141. The minimum distance between the portion of the heating body 22 located in the drain pipe 14 and the corresponding discharge port in the extending direction of the drain pipe 14 is d4, where d4 ≥ 100 mm. For example, the drain pipe 14 extends in the vertical direction, the discharge port is located at the lower end of the drain pipe 14, the heating element 21 is accommodated in the drain pipe 14, and the distance between the bottom of the heating element 21 and the discharge port in the vertical direction is d4.

[0120] For example, the minimum distance d4 between the discharge port and the heating element 21 in the extension direction of the drain pipe 14 can be 100 mm, 110 mm, 120 mm, 130 mm, 140 mm, 150 mm, etc.

[0121] For example, refer to Figure 11 , Figure 11The dashed lines in the diagram represent the distribution of the heating body 22 within the water receiving tank 11.

[0122] By ensuring that the minimum distance d4 between the discharge port and the heating element 21 in the extension direction of the drain pipe 14 is ≥100mm, when relevant personnel clean the discharge port, it is possible to prevent relevant personnel from touching the heating element 21 with their hands, thus avoiding the danger to relevant personnel caused by damage or leakage of the heating element 21, and improving the safety of the water receiving tray assembly 101.

[0123] Reference Figure 3 According to some embodiments of the present invention, the water receiving tank 11 includes a plurality of sub-water receiving tanks 112 arranged at intervals, and a plurality of drain pipes 14. Each sub-water receiving tank 112 is provided with at least one drain pipe 14, and each sub-water receiving tank 112 and the corresponding drain pipe 14 share a heating component 21.

[0124] For example, a portion of the heating element 21 is located in the sub-water tank 112, and another portion of the heating element 21 is located in the drain pipe 14. The heating element 21 passes through the drain hole 141 to enter the drain pipe 14 from the sub-water tank 112.

[0125] By including multiple sub-collecting tanks 112 in the water receiving tank 11, and each sub-collecting tank 112 being connected to at least one drain pipe 14, the multiple sub-collecting tanks 112 can more fully collect water from the water receiving tray assembly 101, and drain the water from the water receiving tank 11 through the drain pipe 14, thus more effectively preventing ice blockage in the drain pipe 14 and drainage difficulties. By having the sub-collecting tanks 112 and the drain pipe 14 connected to them share a single heating element 21, the number of heating elements 21 can be reduced, the installation difficulty of the heating elements 21 can be decreased, and the installation efficiency can be improved.

[0126] Reference Figure 3 and Figure 4 According to some embodiments of the present invention, a water receiving trough 11 is formed on the edge of the water receiving tray and extends circumferentially along the water receiving tray component 1. By forming the water receiving trough 11 on the edge of the water receiving tray and extending circumferentially along the water receiving tray component 1, the water receiving trough 11 is located at the end of the water receiving tray component 1. The water receiving trough 11 can collect water on the water receiving tray assembly 101 more fully and concentrate the water in the circumferential position of the water receiving assembly, which facilitates centralized water discharge and avoids interference between the water receiving trough 11 and other components.

[0127] Reference Figure 3According to some embodiments of the present invention, the water receiving tank 11 includes a plurality of sub-water receiving tanks 112, which are spaced apart along the circumferential direction of the water receiving tray component 1. Adjacent sub-water receiving tanks 112 are spaced apart from each other, and each sub-water receiving tank 112 extends circumferentially along the water receiving tray component 1. By including a plurality of sub-water receiving tanks 112 in the water receiving tank 11, and by arranging the sub-water receiving tanks 112 spaced apart along the circumferential direction of the water receiving tray component 1, the plurality of sub-water receiving tanks 112 can more fully collect water from the water receiving tray assembly 101 and concentrate the water in the circumferential position of the water receiving assembly, thus avoiding interference between the water receiving tank 11 and other components.

[0128] For example, the water receiving tank 11 component includes a plurality of drain pipes 14, and the water receiving tank 11 includes a plurality of sub-water receiving tanks 112, each of which is connected to at least one drain pipe 14.

[0129] Reference Figures 3-6 According to some embodiments of the present invention, the water receiving tray component 1 includes a middle frame 15, a water receiving plate 151, and a plurality of water receiving boxes 153. The water receiving plate 151 is disposed on the middle frame 15, and the plurality of water receiving boxes 153 are disposed on the lower side of the water receiving plate 151 and installed inside the middle frame 15. The plurality of water receiving boxes 153 are arranged at intervals along the circumference of the water receiving plate 151. Each water receiving box 153 defines a sub-water receiving trough 112. A water receiving port 152 is formed on the water receiving plate 151. The water receiving port 152 is located directly above the sub-water receiving trough 112 and communicates with the sub-water receiving trough 112.

[0130] By including a water receiving platform and a water receiving box 153 in the water receiving tray component 1, the water receiving box 153 is located at the bottom of the water receiving platform, and a water receiving trough 11 is formed inside the water receiving box 153. The water receiving platform can collect condensate or defrost water from the heat exchanger as a whole, and the water receiving trough 11 can collect the water in the water receiving platform for centralized discharge and treatment. By placing the water receiving box 153 at the edge of the water receiving platform in the circumferential direction, interference between the water receiving box 153 and other components can be avoided.

The heat insulation support plate 162 is disposed outside the water receiving box 153 and defines a heat insulation cavity 163 between itself and the outer surface of the water receiving box 153. The heat insulation layer 161 is accommodated in the heat insulation cavity 163, and the heat insulation support plate 162 is connected to the water receiving box 153.

[0132] For example, the insulation layer 161 can be attached to the bottom of the water receiving box 153.

[0133] For example, when connecting the insulation support plate 162, the insulation layer 161 and the water receiving box 153, first place the insulation layer 161 at the bottom of the water receiving box 153, then install the insulation layer 161 and the water receiving box 153 together into the insulation space through the installation port of the water receiving box 153, and finally connect the insulation support plate 162 and the water receiving box 153.

[0134] For example, the insulation support plate 162 is connected to the side wall of the water receiving box 153 by fasteners. Since the water in the water receiving box 153 will eventually be located at the bottom of the water receiving box 153 under its own gravity, by connecting the insulation support plate 162 to the side wall of the water receiving box 153 by fasteners, the contact between the fasteners and water can be reduced, thus reducing the rusting of the fasteners.

[0135] By including an insulation component 16 in the water tray assembly 101, and the insulation component 16 including an insulation layer 161, the insulation layer 161 is disposed at the slanted portion of the water receiving box 153. The insulation layer 161 can insulate the water receiving box 153, reducing the heat dissipated from the water receiving box 153, reducing heat loss, and improving the heating efficiency of the heating element 21. By including an insulation support plate 162 in the water tray assembly 101, the insulation support plate 162 and the water receiving box 153 define an insulation cavity 163, and the insulation layer 161 is accommodated in the insulation cavity 163. The insulation support plate 162 can support the insulation layer 161 upwards, preventing the insulation layer 161 from falling downwards and losing its insulation effect. This makes the insulation effect of the insulation layer 161 on the water receiving box 153 more sufficient.

The wall of the screw hole is provided with an internal thread. The locking component 164 locks the bracket and the heating component 2 through the connection between the external thread and the internal thread.

[0138] For example, refer to Figure 6 The locking member 164 includes a snap-fit ​​member, which includes an abutting part. The abutting part abuts against the side of the second folded edge facing the mounting cavity in the vertical direction. The abutting part is connected to the thermal insulation support plate 162 by an interference fit.
