[0041] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] In existing technology, heat pump units include a drip tray located below the heat exchanger. The drip tray collects defrost water dripping from the heat exchanger and discharges the defrost water from the heat pump unit. Both the heat exchanger and the drip tray are annular. The inner side of the heat exchanger contains some of the heat pump unit's piping, such as a gas collector pipe and a liquid distributor pipe, both of which are connected to the heat exchanger. During rainy or snowy weather, rainwater or snowmelt can come into contact with the heat pump unit's piping through the inner side of the heat exchanger and the drip tray, entering the piping and making it more susceptible to damage, thus affecting the performance and lifespan of the heat pump unit.

[0043] Based on this, this application provides a water collection tray structure. Each guide channel on the frame collects defrost water dripping from the heat exchanger. Each guide channel is connected to a drain hole, allowing the defrost water to flow into the drain hole and be discharged through the drain hole. A water collection tray panel collects rainwater from inside the heat exchanger. The periphery of the panel connects to one side of the guide channel opening, guiding water from the panel to flow into the guide channel. Rainwater or snowmelt is then discharged through the guide channel and drain hole, reducing contact between rainwater or snowmelt and the heat pump unit's piping. This reduces the likelihood of rainwater or snowmelt entering the heat pump unit's piping, thus protecting the piping and ensuring the heat pump unit's performance and lifespan.

[0044] The technical solutions of this application and how they solve the aforementioned technical problems are described in detail below with specific embodiments. These specific embodiments may exist independently or in combination with each other. Identical or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0045] Reference Figures 1 to 7 As shown, the water receiving tray structure 10 provided in this application embodiment includes a frame 100 and a water receiving tray panel 200. The frame 100 has a drain hole 111 and a plurality of guide grooves 101 communicating with the drain hole 111. At least some of the slots of the guide grooves 101 are used to be opposite to the bottom of the heat exchanger 20 of the heat pump unit.

[0046] The water receiving tray panel 200 is located inside the frame 100. At least a portion of the periphery of the water receiving tray panel 200 is connected to one side of the opening of at least a portion of the guide channel 101. The water receiving tray panel 200 is used to guide the water on the water receiving tray panel 200 into the guide channel 101.

[0047] In low-temperature environments, frost easily forms on the heat exchanger 20 of the heat pump unit, leading to a decrease in heat exchange efficiency and affecting the performance of the heat pump unit. At this time, the heat pump unit will defrost to melt the frost on the heat exchanger 20 into defrost water, which then drips downwards. The heat exchanger 20 is located above the water receiving pan structure 10, and the bottom of the heat exchanger 20 is opposite the opening of the guide channel 101. The guide channel 101 collects the defrost water dripping from the heat exchanger 20, allowing the defrost water to drip into the guide channel 101 under gravity.

[0048] Each guide channel 101 is connected to the drain hole 111 so that each guide channel 101 can guide defrosting water into the drain hole 111 and discharge it out of the frame 100 through the drain hole 111.

[0049] At least a portion of the guide channel 101 surrounds the periphery of the water receiving tray panel 200, and the periphery of the water receiving tray panel 200 is connected to one side of the guide channel 101. During rainy or snowy weather, the water receiving tray panel 200 is used to collect rainwater or snowmelt to prevent it from contacting electrical components or other sensitive components in the heat pump unit, reducing damage to these components and ensuring the safe and reliable operation of the heat pump unit. The water receiving tray panel 200 also guides rainwater or snowmelt on it towards its periphery, allowing it to flow through the opening of the guide channel 101 into the channel itself, thus reducing the accumulation of rainwater on the water receiving tray panel 200.

[0050] In some examples, when there are many drain holes 111, defrosting water is discharged independently through each drain hole 111, making it difficult to control the drainage of each drain hole 111. This is especially true when installed in densely populated areas, where multiple drain holes 111 can cause water accumulation on the ground, increasing the safety hazard of pedestrians slipping. In this application, there is only one drain hole 111, so that water on the water receiving tray structure 10 can be discharged centrally through the drain hole 111. The defrosting water is guided to the drain hole 111 through each guide channel 101 and discharged centrally through the drain hole 111. This solves the problem caused by the dispersed arrangement of multiple drain holes 111. At the same time, only one external drain pipe needs to be installed to connect to the drain hole 111 to discharge the water on the water receiving tray structure 10 centrally. The installation of the external drain pipe is more convenient, making it easier and more convenient to control the drainage of the external drain pipe.

[0051] The water receiving tray structure 10 provided in this application embodiment receives defrosting water dripping from the heat exchanger 20 through each guide channel 101 on the frame 100. Each guide channel 101 is connected to the drain hole 111 so that each guide channel 101 can guide the defrosting water to the drain hole 111, and then the defrosting water can be discharged from the water receiving tray structure 10 through the drain hole 111. By setting up a water collection tray panel 200 to collect rainwater, and connecting the periphery of the water collection tray panel 200 to one side of the groove opening of the guide channel 101, the water on the water collection tray panel 200 can be guided to flow through the periphery of the water collection tray panel 200 into the guide channel 101. At the same time, rainwater or snow water can be discharged from the water collection tray structure 10 through the guide channel 101 and the drain hole 111, reducing the contact between rainwater or snow water and the pipeline of the heat pump unit, thereby reducing the possibility of rainwater or snow water entering the pipeline of the heat pump unit, thus protecting the pipeline of the heat pump unit and ensuring the performance and service life of the heat pump unit.

[0052] Reference Figure 4 and Figure 5 In some embodiments, the water receiving tray panel 200 has at least one inclined portion 230 for guiding water flow on the water receiving tray panel 200 into the guide channel 101.

[0053] For example, the inclined portion 230 can be an inclined surface or an arc surface. The inclined portion 230 is located on the upper surface of the water receiving tray panel 200. The inclined portion 230 is inclined towards a portion of the periphery of the water receiving tray panel 200. Water on the water receiving tray panel 200 can flow along the inclined portion 230 to the periphery of the water receiving tray panel 200 under its own gravity, and flow into the guide channel 101 through the periphery of the water receiving tray panel 200 and the opening of the guide channel 101.

[0054] Specifically, the inclined portion 230 has a first side and a second side, the first side being higher than the second side, and the second side being connected to one side of the opening of the guide channel 101. The inclined portion 230 is used to guide the water on the inclined portion 230 to flow toward the second side, and can flow into the guide channel 101 through the second side and the opening of the guide channel 101.

[0055] In some embodiments, the central region of the drip tray panel 200 is higher than the periphery of the drip tray panel 200.

[0056] In this way, the water on the water receiving tray panel 200 can flow towards the periphery of the water receiving tray panel 200 under its own gravity, and thus the water on the water receiving tray panel 200 can flow into the guide channel 101.

[0057] Specifically, an inclined portion 230 is formed between the central region of the water receiving tray panel 200 and at least a portion of the periphery of the water receiving tray panel 200, which is inclined toward the guide channel 101. The lowest point of the inclined portion 230 is located on one side of the guide channel 101, and the water flow on the water receiving tray panel 200 is guided to the periphery of the water receiving tray panel 200 through the inclined portion 230.

[0058] Reference Figure 7 and Figure 9 As shown, in some embodiments, the water receiving tray structure 10 provided in this application embodiment further includes a support member 300, which is connected to the water receiving tray panel 200. The support member 300 is used to make the central area of ​​the water receiving tray panel 200 protrude toward the side away from the guide groove 101.

[0059] The support member 300 is located below the water receiving tray panel 200 and is connected to the water receiving tray panel 200. The support member 300 supports the water receiving tray panel 200 to improve the structural strength of the water receiving tray panel 200. At the same time, it can make the central area of ​​the water receiving tray panel 200 bulge upward, so that the water on the water receiving tray panel 200 can flow along the water receiving tray panel 200 to the guide groove 101 on the periphery of the water receiving tray panel 200 under the action of gravity.

[0060] In some examples, the support member 300 has an arcuate surface, and opposite sides of the support member 300 are connected to the frame 100 to secure the support member 300 to the frame 100. The arcuate surface is connected to the lower surface of the drip tray panel 200, and the apex of the arcuate surface is connected to the central region of the drip tray panel 200, so that the central region of the drip tray panel 200 bulges upward.

[0061] Reference Figure 5 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, in a specific implementation, the support member 300 includes a first support beam 310 and at least one second support beam 320. The two sides of the second support beam 320 are connected to the water receiving tray panel 200. The first support beam 310 is disposed between the middle of the second support beam 320 and the water receiving tray panel 200, so that the middle area of ​​the water receiving tray panel 200 protrudes toward the side away from the guide groove 101.

[0062] The second support beam 320 is located below the water tray panel 200, and both sides of the second support beam 320 are connected to the water tray panel 200 along its length. The first support beam 310 is located between the second support beam 320 and the water tray panel 200, and the first support beam 310 is connected to the middle of the second support beam 320 along its length. The first support beam 310 raises the middle area of ​​the water tray panel 200, causing the middle area of ​​the water tray panel 200 to bulge towards the side away from the second support beam 320. This forms a guide slope between the connection between the water tray panel 200 and the second support beam 320 and the periphery of the water tray panel 200, allowing rainwater on the water tray panel 200 to flow along the guide slope to the periphery of the water tray panel 200.

[0063] For example, there are at least two second support beams 320, each parallel to the others and spaced apart. The length direction of the first support beam 310 is perpendicular to that of the second support beams 320.

[0064] Specifically, the longitudinal section of the first support beam 310 is U-shaped, and the top surface of the first support beam 310 is connected to the water receiving tray panel 200. The first support beam 310 has at least one mating part 311, which mates with the second support beam 320 to position the first support beam 310. For example, the mating part 311 can be a slot, and part of the second support beam 320 is located in the slot.

[0065] In some examples, the second support beam 320 is connected to the water tray panel 200 by screws, and the first support beam 310 is connected to the water tray panel 200 by screws.

[0066] In some examples, the second support beam 320 includes a first support plate 321, a second support plate 322, and a third support plate 323 arranged sequentially. The first support plate 321 and the third support plate 323 are located on the same side of the second support plate 322 and are parallel to each other. Both ends of the first support plate 321 abut against the frame 100 along its length, and both ends of the third support plate 323 abut against the frame 100 along its length. The second support plate 322 is connected to the bottom surface of the water receiving tray panel 200. The first support plate 321 and the third support plate 323 are used to improve the strength of the second support plate 322 and prevent deformation of the second support plate 322.

[0067] In some examples, the second support beam 320 has at least two first positioning portions 324, each located at one end of the second support beam 320 along its length. The frame 100 has at least two second positioning portions 171, with the first positioning portions 324 and 171 correspondingly connected to each other to position the second support beam 320. For example, the first positioning portion 324 is a first protrusion located on the second support plate 322, and the second positioning portion 171 is a first recess matching the first protrusion located on the flange of the frame 100, with the first protrusion inserted into the first recess. The shape and number of the first protrusions can be adapted according to actual needs; for example, the first protrusion may be semi-circular, and the second support plate 322 may have four first protrusions.

[0068] In practice, the first support beam 310 is connected to the central region of the water receiving tray panel 200. This allows the protrusion on the water receiving tray panel 200 to be located in the central region of the water receiving tray panel 200, thereby making the distance between the guide slope formed on the water receiving tray panel 200 and the periphery of the water receiving tray panel 200 more even, thus facilitating the flow of rainwater on the water receiving tray panel 200 along the guide slope into the guide channel 101.

[0069] Reference Figure 1 , Figure 4 and Figure 9 As shown, in some embodiments, the water tray panel 200 includes a panel body 210 and at least one enclosure 220 disposed on the panel body 210. The panel body 210 has at least one clearance hole 211 for clearing at least one of the gas collection pipe and liquid distribution pipe of the heat pump unit. The enclosure 220 surrounds the periphery of the clearance hole 211.

[0070] The gas collecting pipe is used to transport low-pressure refrigerant gas to the compressor of the heat pump unit, and the liquid dispensing pipe is used to transport high-pressure refrigerant liquid to the expansion valves of the heat pump unit. The gas collecting pipe and the liquid dispensing pipe are connected to the heat exchanger 20. By providing a clearance hole 211 on the panel body 210, at least one of the gas collecting pipe and the liquid dispensing pipe passes through the clearance hole. A barrier 220 is provided around the clearance hole 211 to prevent rainwater from flowing into the clearance hole 211, thereby reducing the probability of rainwater flowing onto the gas collecting pipe and the liquid dispensing pipe, reducing the damage caused by rainwater entering the gas collecting pipe or the liquid dispensing pipe, reducing the impact of rainwater on the overall performance and service life of the heat pump unit, and reducing the risk of freezing damage to the pipes of the heat pump unit in low-temperature environments.

[0071] The shape of the clearance hole 211 can be adapted to actual needs, and the shape of the enclosure 220 matches the shape of the clearance hole 211. For example, the clearance hole 211 is a racetrack-shaped hole.

[0072] In a specific implementation, at least two guide grooves 101 are connected in sequence to form a guide channel. The drain hole 111 is located at the lowest end of the guide channel. The bottom of the guide groove 101 is inclined relative to the horizontal plane. The guide channel gradually rises from the side close to the drain hole 111 to the side away from the drain hole 111.

[0073] In this way, the defrosting water in the guide channel can flow along the guide channel to the lowest end of the guide channel, namely the drain hole 111, under the action of gravity, so that the defrosting water can be discharged through the drain hole 111.

[0074] Understandably, in low-temperature environments and snowy weather conditions, heat pump units frequently defrost to ensure their performance. Defrost water dripping into the guide channel 101 is prone to freezing, hindering its flow and potentially causing blockage of the drain hole 111. If defrost water cannot drain in time, it may overflow the guide channel 101, easily damaging components of the heat pump unit and affecting its stable operation. In this application, the bottom of the guide channel 101 is inclined relative to the horizontal plane to increase the flow rate of the defrost water within it. This allows the defrost water to effectively wash away the thin ice layer at the bottom of the guide channel 101, reducing the thickness of the ice layer and preventing it from extending to the drain hole 111 and causing blockage.

[0075] Understandably, the angle between the bottom of the guide channel 101 and the horizontal plane can be adapted to actual needs.

[0076] Reference Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, in a specific implementation, the flow guide 101 includes two first flow guides 121, two second flow guides 131, two third flow guides 141, and a fourth flow guide 161. The first flow guides 121, the second flow guides 131, and the third flow guides 141 surround the periphery of the water receiving tray panel 200.

[0077] The drain hole 111 is disposed between the two first guide channels 121. The second guide channel 131 is connected to the first guide channel 121. The first guide channel 121 and the corresponding second guide channel 131 form a guide channel. The fourth guide channel 161 is connected to the third guide channel 141 and the drain hole 111. The third guide channel 141 and the fourth guide channel 161 form a guide channel.

[0078] The bottom of the first guide channel 121 is inclined towards the drain hole 111, and the bottom of the second guide channel 131 is inclined towards the side of the first guide channel 121 away from the drain hole 111. The first guide channel 121 and the second guide channel 131 correspond one-to-one, and the corresponding first guide channel 121 and the second guide channel 131 together form a guide channel. The bottom of the third guide channel 141 is inclined towards the side of the fourth guide channel 161 away from the drain hole 111, and the bottom of the fourth guide channel 161 is inclined towards the drain hole 111. The third guide channel 141 and the fourth guide channel 161 together form a guide channel.

[0079] For example, the projections of the two first guide channels 121 onto the horizontal plane extend in the same direction, the projections of the two third guide channels 141 onto the horizontal plane extend in the same direction, and the two second guide channels 131 are parallel to each other.

[0080] This results in multiple flow channels on the frame 100, with each channel having a shorter flow path, which in turn reduces the time required for defrost water to flow to the drain hole 111, thus improving the efficiency of defrost water discharge.

[0081] Specifically, the frame 100 includes a first mounting frame 110, two second mounting frames 120, and two third mounting frames 130. A drain hole 111 is located on the first mounting frame 110. The first mounting frame 110 connects to the two second mounting frames 120, and the third mounting frames 130 are connected to the side of the second mounting frames 120 away from the first mounting frame 110. The second mounting frames 120 have a first guide groove 121, and the third mounting frames 130 have a second guide groove 131.

[0082] For example, the first mounting frame 110 is connected to the second mounting frame 120 by screws, and the second mounting frame 120 is connected to the third mounting frame 130 by screws.

[0083] The frame 100 also includes two fourth mounting frames 140, a fifth mounting frame 150, and a sixth mounting frame 160. The fourth mounting frames 140 are connected to the side of the third mounting frame 130 away from the second mounting frame 120. The fifth mounting frame 150 connects the two fourth mounting frames 140, and the sixth mounting frame 160 connects the fifth mounting frame 150 and the first mounting frame 110. The fourth mounting frame 140 has a third guide groove 141, and the sixth mounting frame 160 has a fourth guide groove 161.

[0084] For example, the third mounting frame 130 and the fourth mounting frame 140 are connected by screws, and the fourth mounting frame 140 and the fifth mounting frame 150 are connected by screws.

[0085] In some examples, the projection of the water tray panel 200 onto the horizontal plane is rectangular. The first mounting frame 110, the second mounting frame 120, the third mounting frame 130, the fourth mounting frame 140, and the fifth mounting frame 150 are all located around the water tray panel 200. The length direction of the projection of the second mounting frame 120 onto the horizontal plane and the length direction of the projection of the fourth mounting frame 140 onto the horizontal plane are both the first direction, and the length direction of the projection of the third mounting frame 130 onto the horizontal plane is the second direction. The first direction and the second direction are perpendicular to each other. Thus, the first mounting frame 110, the second mounting frame 120, the third mounting frame 130, the fourth mounting frame 140, and the fifth mounting frame 150 together form a rectangular frame.

[0086] Specifically, the first mounting frame 110, the second mounting frame 120, the third mounting frame 130, the fourth mounting frame 140, the fifth mounting frame 150, and the sixth mounting frame 160 all include a base plate, a first side plate, and a second side plate. The first side plate and the second side plate are disposed on the same side of the base plate, and the first side plate, the base plate, and the second side plate together define the guide groove 101. Furthermore, the first side plate may be parallel to the second side plate.

[0087] Drain hole 111 is located on the bottom plate of the first mounting frame 110. The bottom plate of the second mounting frame 120 is inclined toward the bottom plate of the first mounting frame 110, so that the bottom of the first guide channel 121 is inclined toward the drain hole 111. The bottom plate of the sixth mounting frame 160 is inclined toward the bottom plate of the first mounting frame 110, so that the bottom of the fourth guide channel 161 is inclined toward the drain hole 111. The bottom plate of the fourth mounting frame 140 is inclined toward the bottom plate of the fifth mounting frame 150, so that the bottom of the third guide channel 141 is inclined toward the side of the fourth guide channel 161 away from the drain hole 111. The bottom plate of the third mounting frame 130 is inclined toward the end of the corresponding second mounting frame 120 away from the first mounting frame 110, so that the second guide channel 131 is inclined toward the side of the first guide channel 121 away from the drain hole 111. The bottom plates of the two third mounting frames 130 can be parallel to each other.

[0088] In some embodiments, the two ends of the first mounting frame 110 are connected to the two first guide channels 121, and the two ends of the fifth mounting frame 150 are connected to the two third guide channels 141. Both the first mounting frame 110 and the fifth mounting frame 150 have a communication port, which is connected to the fourth guide channel 161, so that the fourth guide channel 161 is connected to the third guide channel 141 and the drain hole 111.

[0089] Specifically, at least one first engaging portion is provided on each opposite side of the connecting port, and at least two second engaging portions matching the first engaging portions are provided at both ends of the sixth mounting frame 160 along its length direction. The first engaging portions and the second engaging portions engage one-to-one, so that the sixth mounting frame 160 connects the first mounting frame 110 and the fifth mounting frame 150. For example, the second engaging portion is a second protrusion, and the first engaging portion is a second recess matching the second protrusion. The shape of the second protrusion can be adapted according to actual needs; for example, the second protrusion can be rectangular.

[0090] In some embodiments, the frame 100 has a plurality of flanges 170, each flange 170 being correspondingly disposed on the second mounting frame 120, the third mounting frame 130, the fourth mounting frame 140, and the sixth mounting frame 160. The first side plates of the second mounting frame 120, the third mounting frame 130, and the fourth mounting frame 140 are close to the water tray panel 200, and a portion of the first side plate is folded towards the side opposite to the second side plate to form the flange 170. The flange 170 is connected to the periphery of the water tray panel 200. Furthermore, each flange 170 is located on the same horizontal plane to facilitate the connection of each flange 170 to the periphery of the water tray panel 200.

[0091] For example, the periphery of the drip tray panel 200 is fixedly connected to the flange 170 by screws.

[0092] In some examples, screws are connected in sequence via the drip tray panel 200 and the first support beam 310 to the flange 170 on the sixth mounting frame 160. The first support beam 310 has a mating part 311, one of which is used to mate with a portion of the sixth mounting frame 160.

[0093] Reference Figure 1 , Figure 4 and Figure 7 As shown, in a specific implementation, the water receiving tray structure 10 provided in this application embodiment also includes a drain pipe 400. The drain pipe 400 is disposed on the side of the frame 100 away from the water receiving tray panel 200, and the drain pipe 400 is connected to the drain hole 111.

[0094] The drain pipe 400 is installed on the bottom surface of the frame 100. The drain pipe 400 is used to orderly discharge water discharged through the drain hole 111 into the water receiving tray structure 10. In this application, there is only one drain hole 111 and one drain pipe 400, which reduces the number of drainage points of the drain pipe 400 and facilitates centralized drainage control. Therefore, when installed in residential areas and densely populated areas, it can reduce the possibility of water accumulation on the ground and the possibility of pedestrians slipping.

[0095] Reference Figure 1 , Figure 4 , Figure 6and Figure 11 As shown, in a specific implementation, the water receiving tray structure 10 provided in this application embodiment also includes a plurality of support seats 500. Each support seat 500 is spaced apart on the frame 100, and the support seat 500 is opposite to the bottom of the guide channel 101. The support seat 500 is used to support the heat exchanger 20.

[0096] To facilitate the mounting of the heat exchanger 20 on the water receiving tray structure 10, multiple spaced support seats 500 are provided on the frame 100. The heat exchanger 20 is mounted on each support seat 500 to support the heat exchanger 20, thereby improving the stability and reliability of the heat exchanger 20. Simultaneously, the bottom of the heat exchanger 20 is aligned with the opening of the guide channel 101, allowing defrosting water on the heat exchanger 20 to flow into the guide channel 101 under gravity.

[0097] For example, the support 500 has a through hole 510 to reduce the contact area between the support 500 and the bottom surface of the heat exchanger 20, thereby facilitating the flow of defrosting water on the heat exchanger 20 into the guide groove 101.

[0098] Furthermore, the support base 500 has a support surface that abuts against the bottom surface of the heat exchanger 20. At least a portion of the through hole 510 is located on the support surface. The support surfaces of each support base 500 are located on the same horizontal plane to facilitate support of the heat exchanger 20.

[0099] In some examples, the frame 100 has multiple third latching portions 180, and the support base 500 has at least one fourth latching portion 520. The fourth latching portion 520 and the third latching portions 180 are latched one-to-one to connect the support base 500 to the frame 100. The third latching portion 180 is a latching hole, and the fourth latching portion 520 is a latching plate, which is inserted into the latching hole. Furthermore, the support base 500 has two spaced-apart fourth latching portions 520 to improve the stability of the connection between the support base 500 and the frame 100.

[0100] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a specific implementation, the water receiving tray structure 10 provided in this application embodiment further includes at least one limiting member 600. The limiting member 600 is disposed on the frame 100 or the water receiving tray panel 200. The limiting member 600 is located on at least one side of the guide channel 101 along the extension direction of the guide channel 101. The limiting member 600 is used to limit the heat exchanger 20.

[0101] For example, the limiting member 600 includes a first limiting part 610 and a second limiting part 620. The first limiting part 610 is disposed on the inner side of the guide channel 101, and the second limiting part 620 is disposed on the outer side of the guide channel 101. The first limiting part 610 and the second limiting part 620 are located on the inner and outer sides of the heat exchanger 20, respectively, thereby limiting the heat exchanger 20.

[0102] For example, the first limiting part 610 may be provided on the periphery of the water receiving tray panel 200, and the second limiting part 620 may be provided on the first mounting frame 110 and the fifth mounting frame 150.

[0103] In some examples, the frame 100 further includes a mounting member 190 connected to the first mounting frame 110, with a second limiting portion 620 located on the mounting member 190. Exemplarily, at least a portion of the mounting member 190 is opposite to the second mounting frame 120.

[0104] Furthermore, the first mounting frame 110 is provided with at least one fifth snap-fit ​​portion on the side away from the water receiving tray panel 200, and the mounting member 190 is provided with at least one sixth snap-fit ​​portion that matches the fifth snap-fit ​​portion. The fifth snap-fit ​​portion and the sixth snap-fit ​​portion are snapped together so that the mounting member 190 is connected to the first mounting frame 110.

[0105] In some embodiments, the water tray structure 10 provided in this application also includes a lifting member 700, which is disposed on the bottom surface of the frame 100. The water tray structure 10 is lifted by the lifting member 700, thereby facilitating the installation of the water tray structure 10.

[0106] In some embodiments, the water receiving tray structure 10 provided in this application embodiment further includes a heating belt. The heating belt can be disposed below the frame 100. The frame 100 is heated by the heating belt to prevent the water in the guide channel 101 from freezing, and to ensure that the water in the guide channel 101 is in a flowing state, so that the water in the guide channel 101 can flow along the guide channel 101 to the drain hole 111.

[0107] Furthermore, the water receiving tray structure 10 provided in this application embodiment also includes a plurality of fixing members 800, each fixing member 800 being arranged sequentially at intervals on the bottom surface of the frame 100, and the heating belt being fixed to the bottom of the frame 100 by the fixing members 800.

[0108] Reference Figure 1 and Figure 12 As shown, based on the above embodiments, this application provides a heat pump unit, including a heat exchanger 20 and any of the above-mentioned water receiving pan structures 10, with the bottom of the heat exchanger 20 opposite to the guide groove 101 of the water receiving pan structure 10.

[0109] The specific structure of the water receiving tray structure 10 has been described in detail in the above embodiments and will not be repeated here.

[0110] The heat pump unit provided in this application embodiment has a water receiving pan structure 10 that receives defrost water dripping from the heat exchanger 20 via guide channels 101 on the frame 100. Each guide channel 101 is connected to a drain hole 111, allowing the guide channels 101 to guide the defrost water to the drain hole 111, which then drains the defrost water from the water receiving pan structure 10. A water receiving pan panel 200 is also provided to collect rainwater. Part of the water receiving pan panel 200 protrudes upwards, allowing rainwater on the panel 200 to flow along the protrusion into the guide channels 101. The rainwater then drains from the water receiving pan structure 10 via the guide channels 101 and the drain hole 111. This reduces contact between rainwater and the heat pump unit's piping, thus reducing the possibility of rainwater entering the heat pump unit's piping and protecting the piping to ensure the performance and service life of the heat pump unit.
