Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and in particular to a refrigerator defrosting system and a refrigerator. Background Technology

[0002] To meet user demands for a better user experience, most refrigerators nowadays are frost-free. The defrosting system in existing frost-free refrigerators typically uses an electric heating element placed at the evaporator, utilizing the heat radiation from this element to assist in defrosting.

[0003] However, in this type of defrosting system, the electric heating element has a relatively high power consumption and consumes a lot of energy. Defrosting is carried out through radiation or hot air convection, resulting in low heat conversion efficiency, long defrosting time, and uneven heating. This can easily cause localized overheating of the evaporator, leading to thermal damage to the evaporator and its surrounding components, thus affecting the user experience. Utility Model Content

[0004] Therefore, it is necessary to provide a refrigerator defrosting system and refrigerator that can improve defrosting efficiency, prevent damage from localized overheating of the evaporator, and save energy.

[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0006] A refrigerator defrosting system includes a condenser and an evaporator, and the refrigerator defrosting system further includes:

[0007] The water collection tray mechanism includes a first water collection tray and a second water collection tray. The first water collection tray is located at the bottom of the condenser in the height direction of the refrigerator, and the second water collection tray is located at the bottom of the evaporator in the height direction of the refrigerator.

[0008] A conveying mechanism connects the first water collection tray and the second water collection tray to convey water from the first water collection tray to the second water collection tray or to convey water from the second water collection tray to the first water collection tray.

[0009] Understandably, this application, by setting up a water collection tray mechanism and a conveying mechanism, places the first water collection tray at the bottom of the condenser and the second water collection tray at the bottom of the evaporator, and uses the conveying mechanism to connect the first and second water collection trays. This allows the heat from the condenser's heat dissipation to heat the water in the first water collection tray, which is then conveyed to the second water collection tray. This enables the evaporator to defrost using the heated water. In this way, using water heated by the condenser to assist in defrosting the evaporator consumes less energy, has relatively high heat transfer efficiency, shortens defrosting time, and avoids localized overheating that could cause thermal damage to components. Simultaneously, the defrosted water from the evaporator flows to the second water collection tray and is then conveyed back to the first water collection tray via the conveying mechanism, further assisting the condenser in heat dissipation and improving its overall heat dissipation efficiency.

[0010] In one embodiment, the conveying mechanism includes a conveying pipe and a water pump, one end of the conveying pipe extending into the first water collection tray and the other end extending into the second water collection tray, and the water pump being connected to the conveying pipe.

[0011] Understandably, the water pump provides the power to transport water through the delivery pipe, allowing water to circulate between the first and second water collection trays.

[0012] In one embodiment, the first water collection tray has a water storage layer and an overflow layer in the height direction of the refrigerator, the water storage layer being located below the overflow layer and communicating with the overflow layer.

[0013] The condenser is located in the overflow layer, and one end of the delivery pipe extends into the water storage layer.

[0014] Understandably, some of the water overflowing from the upper layer can be heated by the condenser and then flow to the storage layer for storage. This not only allows the water in the storage layer to be kept warm by the upper overflow layer, reducing the rate of temperature drop after the water is heated by the condenser, making it easier to transport to the second water collection tray to heat and defrost the evaporator, but also the first water collection tray with its double-layer structure has a relatively large capacity, which increases its water storage capacity, prevents excessive defrosting water from overflowing, and improves the user experience.

[0015] In one embodiment, the first water collection tray includes a first body and a partition. The first body has an upward-opening water storage tank in the height direction of the refrigerator. The partition is disposed in the water storage tank and divides the water storage tank in the height direction of the refrigerator to form the water storage layer and the overflow layer.

[0016] In one embodiment, the partition is provided as a polyurethane foam board.

[0017] Understandably, polyurethane foam boards have a thermal insulation function, which can keep the water in the water storage layer warm, allowing the evaporator to use the water in the storage layer for defrosting.

[0018] In one embodiment, the partition has an overflow hole, and one end of the delivery pipe extends into the water storage layer through the overflow hole.

[0019] Understandably, the overflow hole connects the overflow layer and the water storage layer, allowing the water in the overflow layer to be heated by the condenser's heat dissipation and then flow to the water storage layer for insulation, in preparation for defrosting the evaporator.

[0020] In one embodiment, the diameter of the overflow hole is larger than the diameter of the delivery pipe.

[0021] In one embodiment, the height of the second water collection tray is greater than or equal to the height of the evaporator in the height direction of the refrigerator.

[0022] Understandably, this setup allows the evaporator to be completely placed within the second water collection pan and directly exchange heat with the water in the pan, thereby ensuring improved defrosting efficiency of the evaporator.

[0023] In one embodiment, the second water collection tray includes a second body and an edge, the edge being located on the second body away from its bottom wall in the height direction of the refrigerator, and the angle between the edge and the side wall of the second body in the depth direction of the refrigerator is α, 90°≤α<180°.

[0024] Understandably, the combination of the edge and the second main body can form a relatively enclosed water storage space, thereby preventing water from overflowing from the second water collection tray.

[0025] This application also provides the following technical solutions:

[0026] A refrigerator includes the refrigerator defrosting system described in any of the above embodiments.

[0027] Compared with existing technologies, the refrigerator defrosting system and refrigerator described herein utilize a water collection tray mechanism and a conveying mechanism. The first water collection tray is located at the bottom of the condenser, and the second water collection tray is located at the bottom of the evaporator. The conveying mechanism connects the first and second water collection trays, allowing the heat from the condenser's heat dissipation to heat the water in the first water collection tray. The water is then conveyed to the second water collection tray, enabling the evaporator to defrost using the heated water. This method of using water heated by the condenser to assist in defrosting the evaporator consumes less energy, has relatively high heat transfer efficiency, shortens defrosting time, and avoids thermal damage to components caused by localized overheating. Simultaneously, the defrosted water from the evaporator flows to the second water collection tray and is then conveyed back to the first water collection tray, further assisting the condenser in heat dissipation and improving its overall efficiency.

[0040] Please see Figures 1 to 5 This application provides a refrigerator defrosting system 100, including a condenser 10 and an evaporator 20, which is mainly used to improve the defrosting efficiency of the evaporator 20, reduce defrosting energy consumption, and avoid local overheating and thermal damage to the evaporator 20 during defrosting.

[0041] Specifically, the refrigerator defrosting system 100 also includes a water collection tray mechanism 30 and a conveying mechanism 40. The water collection tray mechanism 30 includes a first water collection tray 31 and a second water collection tray 32. The first water collection tray 31 is located at the bottom of the condenser 10 in the height direction of the refrigerator 200, and the second water collection tray 32 is located at the bottom of the evaporator 20 in the height direction of the refrigerator 200. The conveying mechanism 40 connects the first water collection tray 31 and the second water collection tray 32 to convey water in the first water collection tray 31 to the second water collection tray 32 or to convey water in the second water collection tray 32 to the first water collection tray 31.

[0042] It is understood that this application sets up a water collection tray mechanism 30 and a conveying mechanism 40, with the first water collection tray 31 located at the bottom of the condenser 10 and the second water collection tray 32 located at the bottom of the evaporator 20. The conveying mechanism 40 connects the first water collection tray 31 and the second water collection tray 32, thereby using the heat from the condenser 10 to heat the water in the first water collection tray 31. The water is then conveyed to the second water collection tray 32 by the conveying mechanism 40, allowing the evaporator 20 to defrost using the heated water. In this way, using the water heated by the condenser 10 to assist the evaporator 20 in defrosting consumes less energy, and the heat transfer efficiency of water is relatively high, which can shorten the defrosting time and avoid the problem of local overheating causing thermal damage to components. At the same time, the defrosted water from the evaporator 20 flows to the second water collection tray 32, and the defrosting water is then conveyed back to the first water collection tray 31 by the conveying mechanism 40, which can assist the condenser 10 in dissipating heat and improve the heat dissipation efficiency of the condenser 10.

[0043] Here, the defrosting water from the evaporator 20 can be transported to the first water collection tray 31 via the conveying mechanism 40, heated by the condenser 10, and then transported back to the second water collection tray 32 where the evaporator 20 is located. In this way, the defrosting water can be recycled and its evaporation efficiency can be improved. The conveying mechanism 40 also transports the water from the second water collection tray 32 to the first water collection tray 31, which can also prevent the defrosting water in the second water collection tray 32 from overflowing into the refrigerator 200 and affecting the user experience. Furthermore, after being transported to the first water collection tray 31, the water undergoes heat exchange with the condenser 10, and its evaporation speed is faster, thereby accelerating the evaporation of the defrosting water.

[0044] It should be explained that the water in the first water collection tray 31 can be water supplied from the outside, or it can be defrost water after the evaporator 20 defrosts itself.

[0045] like Figures 2 to 4 As shown, in the height direction of the refrigerator 200, the first water collection tray 31 forms a water storage layer 311 and an overflow layer 312. The water storage layer 311 is located below the overflow layer 312 and is connected to the overflow layer 312. The condenser 10 is placed in the overflow layer 312, and one end of the delivery pipe 41 extends into the water storage layer 311. With this configuration, some of the water in the overflow layer 312 can flow to the water storage layer 311 for heat preservation after being heated by the condenser 10. In this way, not only can the water in the water storage layer 311 be kept warm by the upper overflow layer 312, reducing the rate of temperature drop of the water after being heated by the condenser 10, making it easier to deliver it to the second water collection tray 32 to heat and defrost the evaporator 20, but the capacity of the first water collection tray 31 with its double-layer structure is also relatively large, which can increase its water storage capacity, prevent excessive defrosting water from overflowing, and improve the user experience.

[0046] Specifically, the first water collection tray 31 includes a first main body 313 and a partition 314. The first main body 313 has a water storage tank 3131 with an opening 3132 facing upward in the height direction of the refrigerator 200. The partition 314 is disposed in the water storage tank 3131 and divides the water storage tank 3131 in the height direction of the refrigerator 200 to form a water storage layer 311 and an overflow layer 312.

[0047] In one embodiment, the partition 314 is a polyurethane foam board. It is understood that the polyurethane foam board has the function of heat insulation and can keep the water in the water storage layer 311 warm, so that the evaporator 20 can use the water in the water storage layer 311 for defrosting.

[0048] Furthermore, the partition 314 can also be configured as a composite board consisting of a waterproof board and insulation material, a foam glass board, or an extruded polystyrene board, etc., which have both waterproof and insulation properties. Of course, it is not limited to this; the specific partition 314 used can be determined according to the actual situation.

[0049] Furthermore, the partition 314 has an overflow hole 3141, and one end of the conveying mechanism 40 extends into the water storage layer 311 through the overflow hole 3141. It can be understood that the overflow hole 3141 enables the overflow layer 312 and the water storage layer 311 to be connected, so that the water in the overflow layer 312 is heated by the heat dissipation temperature of the condenser 10 and flows to the water storage layer 311 for heat preservation, in preparation for defrosting the evaporator 20.

[0050] Here, the diameter of the overflow hole 3141 is larger than the diameter of the delivery pipe 41. This arrangement allows the overflow layer 312 and the water storage layer 311 to be connected.

[0051] like Figure 3 and Figure 5 As shown, in the height direction of the refrigerator 200, the height of the second water collection tray 32 is greater than or equal to the height of the evaporator 20. This arrangement allows the evaporator 20 to be completely placed within the second water collection tray 32 and to directly exchange heat with the water in the second water collection tray 32, thereby ensuring improved defrosting efficiency of the evaporator 20.

[0052] In one embodiment, the second water collection tray 32 includes a second body 321 and an edge 322. The edge 322 is located on the second body 321 at a point in the height direction of the refrigerator 200 away from its bottom wall, and the angle between the edge 322 and the side wall of the second body 321 in the depth direction of the refrigerator 200 is α, where 90°≤α<180°. It is understood that the combination of the edge 322 and the second body 321 forms a relatively enclosed water storage space, thereby preventing water from overflowing from the second water collection tray 32.

[0053] Here, the angle α between the edge 322 and the side wall of the second body 321 in the depth direction of the refrigerator 200 can be set to values ​​such as 90°, 100°, 130°, 150°, and 170°. Of course, it is not limited to these values, and the specific value of α can be determined according to the actual situation.

[0054] Please continue to refer to this. Figures 2 to 5 The conveying mechanism 40 includes a conveying pipe 41 and a water pump 42. One end of the conveying pipe 41 extends into the first water collection tray 31, and the other end extends into the second water collection tray 32. The water pump 42 is connected to the conveying pipe 41. It can be understood that the water pump 42 can provide conveying power to the conveying pipe 41, so that water can flow between the first water collection tray 31 and the second water collection tray 32.

[0055] Here, one end of the delivery pipe 41 extends into the water storage layer 311 through the overflow hole 3141.

[0056] like Figure 1 and Figure 2 As shown, this application also provides the following technical solutions:

[0057] A refrigerator 200 includes the refrigerator defrosting system 100 of any of the above embodiments.

[0058] It should be explained that, in this embodiment, the condenser 10 is located in the compressor compartment box, which is composed of the compressor compartment cover plate 201 and the refrigerator 200 box body, and the evaporator 20 is located in the refrigerator 200 box body. Both the condenser 10 and the evaporator 20 are components in the existing refrigerator 200 refrigeration system. Through the refrigerator defrosting system 100 of this application, the system can be recycled, and it will not occupy too much space in the refrigerator 200, and the modification cost is low.

[0059] The aforementioned conveying mechanism 40 can be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the water pump 42 to perform corresponding operations, thereby realizing intelligent control of the refrigerator defrosting system 100 and improving the user experience.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
