Description

Technical Field

[0001] The embodiments of the present application relate to refrigeration technology, and more particularly to a refrigerator. Background Art

[0002] The evaporator is a crucial component in a refrigerator's cooling system. Low-temperature coolant passes through the evaporator, exchanging heat with the outside air, vaporizing and absorbing heat to achieve the desired cooling effect. During this heat exchange process, the coolant in the evaporator also condenses water vapor from the air into liquid. A drain pan can be installed at the bottom of the evaporator to collect this condensed liquid.

[0003] The liquid collected in the water tray will frost if it is exposed to low temperatures for a long time, which will prevent the liquid from being discharged from the water tray, and eventually cause frost to accumulate in the water tray. Utility Model Content

[0004] The embodiment of the present application provides a refrigerator that can solve the problem that frost in the water receiving tray of current refrigerators cannot be discharged.

[0005] An embodiment of the present application provides a refrigerator, comprising:

[0006] a housing, including a mounting cavity;

[0007] The water tray is arranged in the installation cavity.

[0008] The drip tray includes:

[0009] Water receiving chamber;

[0010] A drain outlet, connected to the water receiving cavity;

[0011] A refrigeration component is arranged in the installation cavity;

[0012] The refrigeration components include:

[0013] an evaporator, arranged above the bottom wall of the water receiving chamber;

[0014] The defrost pipe is connected to the evaporator and is arranged at the bottom of the water receiving tray and outside the water receiving cavity. At least part of the defrost pipe is in contact with the water receiving tray. The refrigeration component is configured to drive the refrigerant to flow through the defrost pipe.

[0015] The present application provides a refrigerator, wherein a refrigeration component is arranged in an installation cavity of a cabinet, and the refrigeration component can refrigerate the cavity in the cabinet, so that the items placed in the cabinet can be kept in a low-temperature environment for preservation. The evaporator is arranged above the bottom wall of the water receiving cavity of the water receiving tray, so that the liquid condensed on the surface of the evaporator can fall into the water receiving cavity under the action of gravity, so that the liquid can be collected in a centralized manner. The defrost pipe is connected to the evaporator, and the defrost pipe is located at the bottom of the water receiving tray. The coolant with a relatively high temperature can flow through the defrost pipe. The contact between the defrost pipe and the water receiving tray can cause heat exchange between the coolant and the water receiving tray, thereby increasing the temperature of the water receiving tray, and further allowing the frost in the water receiving tray to melt into liquid and be efficiently discharged from the drain outlet of the water receiving tray. The defrost pipe is arranged at the bottom of the water receiving tray, so that the defrost pipe does not hinder the flow of liquid in the water receiving cavity, so that the liquid in the water receiving cavity can be efficiently discharged through the drain outlet.

[0016] In some embodiments, the defrost pipe is bent or folded at the bottom of the water receiving tray.

[0017] This can increase the length of the defrost pipe, so that the defrost pipe and the water receiving tray are in more complete contact, and the heating effect on the frost in the water receiving chamber is better.

[0018] In some embodiments, the defrost tube comprises:

[0019] A plurality of first pipe portions are arranged at intervals along the length direction of the water receiving tray, and the length direction of the first pipe portions intersects with the length direction of the water receiving tray;

[0020] The second pipe portion is located between adjacent first pipe portions and is connected to adjacent first pipe portions. The second pipe portion is configured to connect the plurality of first pipe portions in sequence.

[0021] The plurality of first pipe portions can increase the length of the defrost pipe, and the second pipe portion can be connected to the plurality of first pipe portions, so that the defrost pipe is finally in contact with all parts of the water receiving pan.

[0022] In some embodiments, a mounting groove is provided at the bottom of the water receiving tray, and at least a portion of the defrost pipe is embedded in the mounting groove.

[0023] The defrost pipe is embedded in the installation groove, so that the structure of the defrost pipe arranged on the water receiving tray is more compact.

[0024] In some embodiments, a fixing plate is provided at the bottom of the water receiving tray, the fixing plate covers the defrost pipe, and the fixing plate is connected to the water receiving tray.

[0025] The fixing plate can fix the defrost pipe on the water receiving tray, so that the contact between the defrost pipe and the water receiving tray is tighter and more reliable.

[0026] In some embodiments, the drain port is located on the bottom wall of the water receiving chamber, and the height of the drain port is lower than the height of the bottom wall of the water receiving chamber.

[0027] The height of the drain outlet is lower than the bottom wall of the water receiving chamber so that the liquid in the water receiving chamber can be fully discharged through the drain outlet under the action of gravity.

[0028] In some embodiments, the water tray comprises:

[0029] base plate;

[0030] A first side plate is connected to one side edge of the bottom plate and is vertically arranged on the bottom plate;

[0031] a second side plate connected to the other side edge of the bottom plate and erected on the bottom plate, the second side plate being opposite to the first side plate and spaced apart;

[0032] The back plate is connected to the edge of the bottom plate, and the two sides of the back plate are respectively connected to the first side plate and the second side plate, and the bottom plate, the first side plate, the second side plate and the back plate are surrounded to form a water receiving cavity;

[0033] Among them, the top surface of the bottom plate is the bottom wall of the water receiving cavity, and the drain outlet is set in the middle of the bottom plate. The height of the top surface of the bottom plate gradually decreases in the direction from the first side plate to the drain outlet and in the direction from the second side plate to the drain outlet.

[0034] The drain port is located in the center of the bottom plate, making it more efficient for liquid to drain out through the drain port.

[0035] In some embodiments, the refrigerator further includes a heating tube, which is disposed in the water receiving cavity, and at least a portion of the heating tube contacts the bottom wall of the water receiving cavity, and the heating tube is disposed along the direction of liquid flow in the water receiving cavity.

[0036] The heating pipe can further increase the temperature of the water receiving tray, so that the frost in the water receiving chamber can be melted and discharged more efficiently.

[0037] In some embodiments, the heating tube comprises:

[0038] A plurality of first pipe segments are attached to the top surface of the bottom plate, and the first pipe segments are arranged along a direction from the first side plate to the second side plate, and the plurality of first pipe segments are arranged at intervals along a direction intersecting the direction from the first side plate to the second side plate;

[0039] The second pipe segment is connected to the plurality of first pipe segments in sequence, and a gap is formed between the second pipe segment and the top of the bottom plate.

[0040] The length direction of the first pipe section is consistent with the flow direction of the liquid in the water receiving chamber, so that the first pipe section does not hinder the flow of liquid. The gap between the second pipe section and the water receiving tray is suitable for liquid to flow through, so that the second pipe section does not hinder the flow of liquid either.

[0041] In some embodiments, the first pipe section and the second pipe section are both staggered relative to the drain outlet.

[0042] The first pipe section and the second pipe section will not block the drain outlet, so that the liquid can be discharged through the drain outlet more efficiently. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0067] The evaporator is a crucial component in a refrigerator's cooling system. Low-temperature coolant passes through the evaporator, exchanging heat with the outside air, vaporizing and absorbing heat to achieve the desired cooling effect. During this heat exchange process, the coolant in the evaporator also condenses water vapor from the air into liquid. A drain pan can be installed at the bottom of the evaporator to collect this condensed liquid.

[0068] Liquid collected in the water tray will frost if exposed to low temperatures for a long time, preventing the liquid from draining out of the tray and ultimately causing frost to accumulate in the tray. Therefore, to defrost the frost in the tray and allow it to be drained out of the tray, a method is currently used to heat the frost in the tray, melting it and allowing it to be drained from the tray. However, in this current heating method, the heating device is a defrost pipe extending from the evaporator, which is located in the tray. Although this defrost pipe can fully contact the tray to melt the frost, it hinders the flow of liquid in the tray, preventing the collected liquid from being drained out of the tray efficiently.

[0069] The present application proposes a refrigerator, wherein a refrigeration component is arranged in the installation cavity of the cabinet, and the refrigeration component can refrigerate the cavity in the cabinet, so that the items placed in the cabinet can be kept in a low-temperature environment for preservation. The evaporator is arranged above the bottom wall of the water receiving cavity of the water receiving tray, so that the liquid condensed on the surface of the evaporator can fall into the water receiving cavity under the action of gravity, so that the liquid can be collected in a centralized manner. The defrost pipe is connected to the evaporator, and the defrost pipe is located at the bottom of the water receiving tray. The coolant with a relatively high temperature can flow through the defrost pipe. The contact between the defrost pipe and the water receiving tray can cause heat exchange between the coolant and the water receiving tray, thereby increasing the temperature of the water receiving tray, and further allowing the frost in the water receiving tray to melt into liquid and be efficiently discharged from the drain outlet of the water receiving tray. The defrost pipe is arranged at the bottom of the water receiving tray, so that the defrost pipe does not hinder the flow of liquid in the water receiving cavity, so that the liquid in the water receiving cavity can be efficiently discharged through the drain outlet.

[0070] The present application embodiment proposes a refrigerator, referring to Figure 1 As shown, the refrigerator includes a housing 100. The housing 100 is the foundation of the refrigerator of the present application. The housing 100 provides a mounting base for at least some of the other components of the refrigerator and serves to protect at least some of the other components of the refrigerator. The housing 100 can be made of metal, which improves the structural strength of the housing 100 and thereby enhances the structural stability and reliability of the refrigerator.

[0071] The housing 100 has an installation cavity 110, which is an inner cavity structure of the housing 100. The installation cavity 110 of the housing 100 can be used to install at least some other components of the refrigerator. The housing 100 can also be provided with a refrigeration compartment, which can be used to store items that need to be preserved.

[0072] refer to Figure 2 As shown, the refrigerator of the present application further includes a refrigeration assembly 300, which is disposed in the mounting cavity 110 of the housing 100 so that the refrigeration assembly 300 can be fixedly mounted in the housing 100. The refrigeration assembly 300 can generate cold air in the housing 100 through heat exchange, thereby maintaining a low-temperature environment in the refrigeration compartment of the housing 100, thereby achieving the function of preserving items in the refrigerator.

[0073] refer to Figure 3 As shown, the refrigeration assembly 300 includes an evaporator 310. A coolant can circulate in the refrigeration assembly 300. When the low-temperature coolant passes through the evaporator 310, it can absorb heat from the external air, thereby lowering the temperature of the external air and generating cold gas to lower the temperature of the refrigeration compartment.

[0074] Specifically, the refrigeration assembly may also include a compressor, a condenser, and a throttle. The compressor, condenser, throttle, and evaporator are cyclically connected. When the refrigeration system is operating, the compressor compresses the refrigerant vapor to generate high-temperature, high-pressure refrigerant vapor, and transports the refrigerant vapor to the condenser. The condenser liquefies the high-temperature, high-pressure refrigerant vapor to generate low-temperature, high-pressure refrigerant liquid, which is then transported to the throttle. The throttle reduces the pressure of the refrigerant liquid, converting the high-pressure, low-temperature refrigerant liquid into a low-pressure, low-temperature refrigerant liquid, which is then transported to the evaporator. The evaporator receives the low-pressure, low-temperature refrigerant liquid and causes it to boil under isobaric conditions, absorbing heat and vaporizing it to form refrigerant vapor, thereby lowering the temperature inside the refrigerated room.

[0075] The refrigerator of the present application also includes a water tray 200, which is disposed within the mounting cavity 110 of the housing 100. The water tray 200 includes a water receiving cavity 210, which is a cavity structure within the water tray 200. The top of the water tray 200 is open and communicates with the water receiving cavity 210. An evaporator 310 is disposed above the bottom wall of the water receiving cavity 210 of the water tray 200. It should be understood that when the coolant in the evaporator 310 exchanges heat with the outside air, water vapor in the outside air condenses into liquid. This liquid may exist on the surface of the evaporator 310 and in the space surrounding the evaporator 310. Under the action of gravity, the liquid may fall into the water receiving cavity 210 on one side of the bottom of the evaporator 310. This allows the liquid to be collected in the water receiving cavity 210 of the water tray 200, preventing it from falling onto the surfaces of other refrigerator components within the housing 100, thereby protecting the refrigerator.

[0076] The water receiving tray 200 also includes a drain outlet 220, which is an opening structure on the surface of the water receiving tray 200. The drain outlet 220 is connected to the water receiving chamber 210. The other end of the drain outlet 220 can be connected to the outside of the box body 100 or the structure for storing liquid inside the box body 100 through a pipeline. In this way, the liquid in the water receiving chamber 210 can be discharged from the water receiving chamber 210 to prevent the liquid from overflowing in the water receiving chamber 210.

[0077] It should be understood that when the evaporator 310 lowers the air temperature in the box body 100, the water receiving tray 200 will also be in a lower temperature environment, causing the liquid in the water receiving tray 200 to frost again, and then causing the liquid in the water receiving tray 200 to be unable to be discharged through the drain outlet 220 and accumulate in the water receiving chamber 210.

[0078] The refrigeration assembly 300 of the present application also includes a defrost pipe 320, which is connected to the evaporator 310. Coolant can also flow through the defrost pipe 320. The refrigeration assembly 300 can control the relatively high-temperature coolant to flow through the defrost pipe 320, thereby increasing the temperature of the defrost pipe 320. The defrost pipe 320 is disposed on one side of the bottom of the water receiving pan 200 and contacts the bottom of the water receiving pan 200. This allows heat from the coolant in the defrost pipe 320 to be transferred to the water receiving pan 200, thereby increasing the temperature of the water receiving pan 200. This allows frost in the water receiving chamber 210 to melt into liquid after absorbing the heat transferred from the defrost pipe 320. The liquid is then discharged from the water receiving chamber 210 through the drain port 220 of the water receiving pan 200, preventing frost from accumulating in the water receiving chamber 210.

[0079] The defrost pipe 320 is disposed on one side of the bottom of the water receiving pan 200. This prevents the defrost pipe 320 from coming into contact with the liquid in the water receiving chamber 210 when the water receiving pan 200 is heated, thereby preventing the defrost pipe 320 from being corroded by the liquid. Furthermore, the defrost pipe 320 does not obstruct the flow of liquid in the water receiving chamber 210, allowing the liquid in the water receiving chamber 210 to be more efficiently discharged out of the water receiving chamber 210 through the drain port 220. Ultimately, this improves the reliability and stability of the refrigerator of the present application.

[0080] In some embodiments, reference Figures 3 to 6 As shown, in order to further improve the efficiency of the defrost pipe 320 in melting the frost in the water receiving chamber 210, the defrost pipe 320 of the present application can be bent and arranged at the bottom of the water receiving pan 200. After the defrost pipe 320 is bent, the length of the defrost pipe 320 can be increased, and accordingly, the contact area between the defrost pipe 320 and the water receiving pan 200 can be increased. In this way, the heat of the coolant in the defrost pipe 320 can be more efficiently and fully transferred to the water receiving pan 200, thereby allowing the frost in the water receiving chamber 210 to be more efficiently melted into liquid and more efficiently discharged out of the water receiving chamber 210 through the drain port 220.

[0081] In addition, the defrost pipe 320 of the present application can also be bent, which can increase the length of the defrost pipe 320. Correspondingly, the contact area between the defrost pipe 320 and the water receiving pan 200 can be increased, so that the heat of the coolant in the defrost pipe 320 can be more efficiently and fully transferred to the water receiving pan 200, and the frost in the water receiving chamber 210 can be more efficiently melted into liquid, so as to be more efficiently discharged to the outside of the water receiving chamber 210 through the drain outlet 220.

[0082] In some embodiments, reference Figure 7As shown, in order to allow the defrost pipe 320 to have a curved structure and thus be relatively long, the defrost pipe 320 may include multiple first pipe portions 321. The multiple first pipe portions 321 are spaced apart along the length of the water receiving pan 200 and are connected to each other. Therefore, the multiple first pipe portions 321 can contact the water receiving pan 200 at multiple locations along its length, allowing the multiple locations along its length to respectively contact and exchange heat with the multiple first pipe portions 321. This can increase the overall temperature of the water receiving pan 200 more evenly, and accordingly, the temperature of each area within the water receiving chamber 210 can be evenly increased, allowing frost accumulated in each area within the water receiving chamber 210 to melt more fully and be discharged outside the water receiving chamber 210.

[0083] The defrost duct 320 may further include a second duct portion 322 located between adjacent first duct portions 321. The ends of the second duct portion 322 are connected to two adjacent first duct portions 321, respectively. This allows adjacent first duct portions 321 to communicate with each other through the second duct portion 322, thereby allowing multiple first duct portions 321 to be sequentially connected through the second duct portion 322. The number of second duct portions 322 may be determined based on the number of first duct portions 321. When there are two first duct portions 321, there may be one second duct portion 322, and one second duct portion 322 may connect two first duct portions 321. When there are more than two first duct portions 321, the number of second duct portions 322 may be increased accordingly to ensure that all adjacent first duct portions 321 are connected.

[0084] The second pipe portion 322 is a curved pipe structure, so that the second pipe portion 322 can connect the adjacent first pipe portion 321, and the transition of the second pipe portion 322 is more natural, which can increase the rate at which the coolant flows through the second pipe portion 322, thereby increasing the rate at which the coolant flows through the defrost pipe 320.

[0085] In some embodiments, to make the refrigerator structure of the present application more compact, a mounting groove may be provided on one side of the bottom of the water tray 200. The groove shape of the mounting groove may match the shape of the defrost tube 320, so that at least a portion of the defrost tube 320 can be embedded in the mounting groove. Specifically, when the defrost tube 320 is located in the mounting groove, the inner wall of the mounting groove can fully contact the outer wall of the defrost tube 320. The mounting groove can serve to limit the position of the defrost tube 320, allowing the defrost tube 320 to be more securely fixed to the water tray 200.

[0086] Furthermore, at least a portion of the defrost pipe 320 is embedded in the mounting groove, which reduces the portion of the defrost pipe 320 protruding from the water tray 200. This allows the defrost pipe 320 to be installed on the water tray 200 in a more compact structure, reducing the space occupied by the defrost pipe 320 and the water tray 200 in the mounting cavity 110 of the housing 100. This allows the mounting cavity 110 of the housing 100 to be relatively smaller, making the structure of the refrigerator more compact. Alternatively, more space is available for installing other components within the mounting cavity 110 of the housing 100, facilitating the installation of components within the mounting cavity 110 of the housing 100.

[0087] In some embodiments, the defrost pipe 320 can be completely embedded in the installation groove of the water receiving tray 200, and the side of the bottom wall of the defrost pipe 320 facing away from the installation groove can be flush with the ground of the water receiving tray 200, so that the bottom side of the water receiving tray 200 is a flush structure, which can make the structure of the defrost pipe 320 set on the water receiving tray 200 more compact.

[0088] In some embodiments, reference Figures 4 to 6 As shown, in order to make the defrost pipe 320 more reliably fixed on the water receiving tray 200, the refrigerator of the present application can also be provided with a fixing plate 500, which is covered on the defrost pipe 320 and connected to the water receiving tray 200. In this way, the fixing plate 500 can press the defrost pipe 320 onto the water receiving tray 200, so that the defrost pipe 320 is fixed on the water receiving tray 200.

[0089] Of course, in other embodiments, the defrost pipe 320 may also be fixed to the water receiving tray 200 by bonding, which can also ensure a reliable connection between the defrost pipe 320 and the water receiving tray 200.

[0090] In addition, the defrost pipe 320 may be arranged to abut against the bottom wall of the installation groove, that is, the defrost pipe 320 abuts against the bottom wall of the installation groove in a natural state, so that the defrost pipe 320 is fixed on the water receiving tray 200 .

[0091] In some embodiments, reference Figures 3 to 4 As shown, in order to more efficiently drain the liquid in the water receiving chamber 210 of the water receiving tray 200 through the drain port 220 to the outside of the water receiving chamber 210, the drain port 220 of the water receiving tray 200 can be provided on the bottom wall of the water receiving chamber 210. Specifically, one end of the drain port 220 is located on the bottom wall of the water receiving chamber 210, and the other end of the drain port 220 is located on the bottom wall of the water receiving chamber 210. The liquid in the water receiving tray 200 can be efficiently drained out of the water receiving chamber 210 through the drain port 220 under the action of its own gravity.

[0092] The height of the drain port 220 is lower than the height of the bottom wall of the water receiving chamber 210 , so that the liquid in the water receiving chamber 210 can be discharged from the drain port 220 to the outside of the water receiving chamber 210 under the action of gravity, avoiding liquid accumulation in the water receiving chamber 210 .

[0093] In some embodiments, reference Figures 3 to 4 As shown, in order to make the height of the drain port 220 of the water receiving tray 200 lower than the height of the bottom wall of the water receiving chamber 210, the bottom wall of the water receiving chamber 210 can be configured as an inclined surface. As the height of the bottom wall of the water receiving chamber 210 increases in the direction away from the drain port 220, the liquid in the water receiving chamber 210 flows along the inclined bottom wall of the water receiving chamber 210 toward the drain port 220 and is discharged through the drain port 220.

[0094] In some embodiments, the bottom wall of the water receiving chamber 210 may be configured as a curved surface to ensure that the height of the drain outlet 220 of the water receiving tray 200 is lower than the height of the bottom wall of the water receiving chamber 210. The bottom wall of the water receiving chamber 210 is configured as a curved surface with a gradually increasing height away from the drain outlet 220. This allows the liquid in the water receiving chamber 210 to flow along the inclined bottom wall of the water receiving chamber 210 toward the drain outlet 220, and then be discharged through the drain outlet 220.

[0095] In some embodiments, reference Figures 4 to 6 As shown, the water receiving tray 200 of the present application may include a bottom plate 230, which is the foundation component of the water receiving tray 200 and provides a mounting base for at least some of the other components of the water receiving tray 200. The surface of the bottom plate 230 may constitute the bottom wall of the water receiving cavity 210 of the water receiving tray 200, and the drain outlet 220 of the water receiving tray 200 is located in the center of the bottom plate 230. The height of the top surface of the bottom plate 230 gradually decreases from the edge of the bottom plate 230 to the drain outlet 220, so that the drain outlet 220 is located at the lowest point on the top surface of the bottom plate 230.

[0096] The water receiving tray 200 further includes a first side plate 240 connected to one side edge of the bottom plate 230 and erected on the bottom plate 230. A side surface of the first side plate 240 may constitute a side wall of the water receiving chamber 210.

[0097] The water receiving tray 200 further includes a second side panel 250. The first side panel 240 is connected to the other side edge of the bottom panel 230, and the first side panel 240 is vertically disposed on the bottom panel 230. The second side panel 250 is disposed opposite to the first side panel 240 and can form a side wall on the other side of the water receiving chamber 210.

[0098] The water receiving tray 200 also includes a back plate 260, which is connected to the edge of the bottom plate 230. The back plate 260 is connected on both sides to the first side plate 240 and the second side plate 250, respectively. One side surface of the back plate 260 can form a sidewall of the water receiving chamber 210. Therefore, the bottom plate 230, the first side plate 240, the second side plate 250, and the back plate 260 can enclose and form the water receiving chamber 210. The first side plate 240, the second side plate 250, and the back plate 260 can block liquid splashing after the coolant falls on the bottom plate 230, preventing the liquid from falling on other components. The bottom plate 230, the first side plate 240, the second side plate 250, and the back plate 260 can be integrally formed, thereby enhancing the structural integrity of the water receiving tray 200. The bottom plate 230, the first side plate 240, the second side plate 250 and the back plate 260 can also be prepared separately and then assembled, which can reduce the difficulty of the preparation process of the water receiving tray 200. This application does not limit the specific preparation process of the water receiving tray 200.

[0099] In some embodiments, reference Figure 8 As shown, to further improve the melting efficiency of frost within the water receiving chamber 210 of the water receiving tray 200, the refrigerator of the present application may also be provided with a heating pipe 400. The heating pipe 400 is disposed within the water receiving chamber 210 of the water receiving tray 200, and at least a portion of the heating pipe 400 is in contact with the inner wall of the water receiving chamber 210. The heating pipe 400 can generate heat, and the contact between the heating pipe 400 and the inner wall of the water receiving chamber 210 can transfer the heat to the water receiving tray 200, thereby increasing the temperature within the water receiving chamber 210, thereby accelerating the melting efficiency of frost within the water receiving chamber 210, and allowing the liquid within the water receiving chamber 210 to be discharged more efficiently. The heating pipe 400 is disposed along the direction of liquid flow within the water receiving chamber 210, so that the heating pipe 400 does not hinder the flow of liquid within the water receiving chamber 210.

[0100] The heating tube 400 may be an electric heating tube 400 structure. The heating tube 400 may generate heat when powered on. The heating tube 400 may be electrically connected to the circuit system of the refrigerator so that the heating tube 400 may generate heat when powered on.

[0101] In some embodiments, reference Figures 9 to 10 As shown, the heating tube 400 of the present application can be provided with a plurality of first tube sections 410, and the first tube sections 410 are provided in contact with the top surface of the bottom plate 230, so that the heat generated by the first tube sections 410 can be directly conducted to the bottom plate 230, thereby allowing the frost located on the bottom plate 230, that is, located in the water receiving chamber 210, to be heated and melted.

[0102] It should be understood that liquid that falls into the water receiving chamber 210 of the water receiving tray 200 will fall from the higher portion of the bottom wall of the water receiving chamber 210 to the drain outlet 220, that is, flow from a position near the first side plate 240 and the second side plate 250 toward the drain outlet 220. The first pipe section 410 can be arranged along the direction from the first side plate 240 to the second side plate 250. In this way, the length direction of the first pipe section 410 is in the same direction as the flow direction of the liquid in the water receiving chamber 210. This ensures that the first pipe section 410 does not hinder the flow of liquid in the water receiving chamber 210 toward the drain outlet 220, thereby allowing the liquid to be efficiently discharged from the drain outlet 220.

[0103] The plurality of first pipe sections 410 can be spaced apart along a direction intersecting the direction from the first side plate 240 to the second side plate 250, and the plurality of first pipe sections 410 are connected. Therefore, the plurality of first pipe sections 410 can contact various portions of the water receiving pan 200, allowing the various portions of the water receiving pan 200 to respectively engage in heat exchange with the plurality of first pipe sections 410. This can result in a more uniform increase in the overall temperature of the water receiving pan 200, and accordingly, a more uniform increase in the temperature of each region within the water receiving chamber 210. Frost accumulated in each region within the water receiving chamber 210 can be more fully melted and discharged outside the water receiving chamber 210.

[0104] The heating tube 400 may further include a second tube segment 420, which is located between adjacent first tube segments 410. The ends of the second tube segment 420 are connected to two adjacent first tube segments 410, respectively, so that adjacent first tube segments 410 can be connected through the second tube segment 420, thereby allowing multiple first tube segments 410 to be sequentially connected through the second tube segment 420. The number of second tube segments 420 can be determined based on the number of first tube segments 410. When there are two first tube segments 410, the number of second tube segments 420 can be one, and one second tube segment 420 can connect two first tube segments 410. When there are more than two first tube segments 410, the number of second tube segments 420 will also be increased accordingly to ensure that adjacent first tube portions 321 can all be connected.

[0105] The second pipe section 420 is a curved pipe structure, so that the second pipe section 420 can connect adjacent first pipe portions 321 , and the transition of the second pipe section 420 is more natural.

[0106] There is a gap between the second pipe section 420 and the top side surface of the bottom plate 230, so that the liquid in the water receiving chamber 210 can flow through the gap between the second pipe section 420 and the bottom plate 230, so that the second pipe section 420 will not hinder the liquid in the water receiving chamber 210 from flowing toward the drain outlet 220, so that the liquid in the water receiving chamber 210 can be efficiently discharged through the drain outlet 220.

[0107] In some embodiments, the first pipe section 410 of the present application is offset from the drain outlet 220 of the water receiving tray 200, so that the first pipe section 410 does not cover the drain outlet 220, thereby allowing the liquid in the water receiving cavity 210 of the drain outlet 220 to be fully discharged to the outside of the water receiving cavity 210 through the drain outlet 220.

[0108] The second pipe section 420 of the present application is staggered with the drain outlet 220 of the water receiving tray 200, so that the second pipe section 420 does not cover the drain outlet 220, thereby allowing the liquid in the water receiving cavity 210 of the drain outlet 220 to be fully discharged to the outside of the water receiving cavity 210 through the drain outlet 220.
