DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described embodiments are only part of the embodiments of the present embodiment, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] In the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0034] Refrigerators are common household appliances in people's lives. Refrigerators mainly store food or other items by maintaining a constant low temperature and cold state. In the related art, a defrost heating wire and other devices are usually set at the evaporator of the refrigerator to achieve automatic defrosting of the refrigerator. When the refrigerator is defrosted, the defrost heating wire melts the frost on the evaporator to form defrost water. The generated defrost water is discharged through the drain pipe to the evaporation dish in the compressor compartment for evaporation, and then discharged from the refrigerator.

[0035] In the related art, the drain pipe of the refrigerator runs through the inner tank, foaming layer and bottom plate of the refrigerator to drain the defrost water produced by the evaporator into the evaporating dish of the compressor compartment outside the bottom plate. When assembling the drain pipe, first fix the inner tank and the bottom plate of the refrigerator, then pass one end of the drain pipe through the prefabricated holes of the inner tank and the prefabricated holes of the bottom plate in sequence, and then fill the foaming layer between the inner tank and the bottom plate. When installing the drain pipe, in order to prevent the drain pipe from shrinking and overflowing during foaming, the related art usually wraps a large amount of sponge around the fitting of the drain pipe and the bottom plate, and workers are also required to use PE film for secondary sealing. This is not only complicated to operate, reduces the installation efficiency of the drain pipe, and increases the installation cost, but also the wrapped sponge is easy to fall off, and the sealing effect of the fitting between the drain pipe and the bottom plate is poor, which still causes foaming overflow.

[0036] Refer to the following Figure 1 and Figure 2The utility model provides a refrigerator 1, comprising a box assembly 10, a compressor 20, a condenser 30, an evaporator 40 and a throttling element (not shown in the figure). The compressor 20, the condenser 30, the evaporator 40 and the throttling element are respectively arranged in the box assembly 10. The box assembly 10 comprises an outer shell 11, an inner liner and an insulation layer 14 arranged between the outer shell 11 and the inner liner. Two inner liner can be provided, as an example, the inner liner located at the bottom is the first inner liner 12. The first inner liner 12 can be set as a freezing inner liner, and accordingly, the storage space of the first inner liner 12 is a freezing chamber 1a. The inner liner located above the first inner liner 12 is the second inner liner 13, the second inner liner 13 can be set as a refrigerated inner liner, and the storage space of the second inner liner 13 is a refrigerated chamber 1b. At least part of the evaporator 40 is arranged in the freezing chamber 1a.

[0037] When the refrigerator 1 is in operation, the compressor 20 outputs a high-temperature and high-pressure gaseous refrigerant to the condenser 30, and the high-temperature and high-pressure gaseous refrigerant is condensed into a medium-temperature and high-pressure refrigerant through the condenser 30. The medium-temperature and high-pressure refrigerant passes through the throttling element, so that the pressure and temperature of the refrigerant are further reduced, and the low-temperature and low-pressure liquid refrigerant flows out of the throttling element to the evaporator 40. The low-temperature and low-pressure liquid refrigerant evaporates into a gaseous refrigerant in the evaporator 40. At least part of the evaporator 40 is arranged in the freezing chamber 1a, so that the refrigerant absorbs a large amount of heat in the freezing chamber 1a during the evaporation process, thereby reducing the temperature in the freezing chamber 1a, making it easier to use the freezing chamber 1a to freeze items and realize the refrigeration of the refrigerator 1. The refrigerant coming out of the evaporator 40 is replenished back to the compressor 20 to form a refrigerant circuit. In this way, the refrigerant circulates continuously in the refrigerant circuit to maintain the freezing environment of the freezing chamber 1a (for example, less than -1°C). At the same time, an air duct 15 is provided between the refrigerating compartment 1b and the freezing compartment 1a, so as to transport part of the cold air from the freezing compartment 1a to the refrigerating compartment 1b through the air duct 15, so as to reduce or maintain the low temperature environment of the refrigerating compartment 11b (for example, 2°C to 8°C).

[0038] Figure 2 The schematic structural diagram of the freezer inner tank of the refrigerator 1 before foaming is shown (the foaming layer is not shown so as to facilitate viewing of the drainage assembly). To facilitate the discharge of the generated defrost water, the refrigerator 1 further includes an evaporation dish 50 and a drainage assembly 100. The evaporation dish 50 is arranged above the compressor 20, and the drainage assembly 100 is arranged between the evaporation dish 50 and the inner tank. The drainage assembly 100 discharges the generated defrost water into the evaporation dish 50 for collection. Since the evaporation dish 50 is installed above the compressor compartment, the airflow at the compressor 20 can be used to heat the bottom of the evaporation dish 50, so as to facilitate the heat absorption and evaporation of the defrost water in the evaporation dish 50.

[0039] In order to prevent the drainage pipe of the drainage component from shrinking and overflowing during foaming, the utility model further provides a drainage component 100, and the drainage component 100 provided by the utility model will be described in detail below.

[0040] See also Figures 3 to 5 The drain assembly 100 includes a drain pipe 120, at least one elastic body 130, a stopper 140 and a bottom plate 110. The drain pipe 120 has a first open end 121 and a second open end 122 spaced apart along the axial direction of the drain pipe 120. At least one elastic body 130 has a first end 131 close to the first open end 121 and a second end 132 close to the second open end 122, the first end 131 is fixedly arranged on the outer wall of the drain pipe 120, and the second end 132 is spaced apart from the outer wall of the drain pipe 120. The stopper 140 is sleeved on the outer wall of the drain pipe 120, and the stopper 140 is arranged between the elastic body 130 and the second open end 122 of the drain pipe 120. The bottom plate 110 is provided with a mounting hole 111, and the first open end 121 of the drain pipe 120 is inserted into the mounting hole 111, so that the elastic body 130 and the stopper 140 respectively seal the mounting hole 111 on both sides of the bottom plate 110.

[0041] It should be noted that the inner tank of the refrigerator has a prefabricated hole. When installing the drain pipe 120, the first open end 121 of the drain pipe 120 can be passed through the prefabricated hole on the inner tank and the installation hole 111 on the bottom plate 110 in sequence until the first open end 121 of the drain pipe 120 is close to the evaporating dish, and the second open end 122 of the drain pipe 120 is connected to the prefabricated hole of the inner tank of the refrigerator, so that the defrost water generated can be guided to the evaporating dish outside the bottom plate 110 through the drain pipe 120.

[0042] The bottom plate 110 can be used to form an installation compartment for accommodating the compressor, and to carry the drain pipe 120, and guide the drain pipe 120 to the evaporation dish. In addition, after the drain pipe 120 is installed, an insulation layer needs to be formed between the bottom plate 110 and the inner container to improve the insulation effect of the refrigerator. At this time, the portion of the drain pipe 120 located between the inner container and the bottom plate 110 is buried in the insulation layer. Optionally, the bottom plate 110 can be made of stainless steel to improve the structural strength of the bottom plate 110 and prevent rust.

[0043] The elastic body 130 is used to fix the drain pipe 120 and the bottom plate 110, so as to prevent the drain pipe 120 from shifting relative to the bottom plate 110, thereby avoiding a gap between the two. The elastic body 130 can be elastically deformed. When the first end 131 of the elastic body 130 is inserted into the mounting hole 111 of the bottom plate 110 along with the first open end 121 of the drain pipe 120, the elastic body 130 is squeezed by the side wall of the mounting hole 111 to be elastically deformed, so that the second end 132 of the elastic part approaches the side wall of the drain pipe 120, and the interval between the second end 132 of the elastic body 130 and the side wall of the drain pipe 120 is gradually reduced, which is equivalent to reducing the cross-sectional area of ​​the assembly formed by the drain pipe 120 and the elastic part. After the elastomer 130 completely passes through the mounting hole 111 of the base plate 110, the elastomer 130 is no longer squeezed by the side wall of the mounting hole 111, and the elastomer 130 restores its elastic deformation, that is, the interval between the second end 132 of the elastomer 130 and the side wall of the drain pipe 120 is restored, so that the second end 132 of the elastomer 130 can be supported and fixed on the outside of the mounting hole 111 of the base plate 110, thereby preventing the drain pipe 120 from moving relative to the base plate 110 in the direction from the first opening end 121 to the second opening end 122.

[0044] The stopper 140 is used to cooperate with the elastic body 130 to fix the drain pipe 120 and the bottom plate 110. In the process of the elastic body 130 being inserted into the mounting hole 111 of the bottom plate 110 along with the first opening end 121 of the drain pipe 120, when the elastic body 130 is installed in place, the stopper 140 just abuts against the wall surface of the bottom plate 110 facing the second opening end 122. At this time, the stopper 140 can prevent the drain pipe 120 from moving relative to the bottom plate 110 in the direction from the second opening end 122 to the first opening end 121. Thus, the stopper 140 and the elastic body 130 cooperate with each other, so that the drain pipe 120 and the bottom plate 110 are relatively fixed, and the elastic body 130 and the stopper 140 are respectively fixed on the opposite sides of the bottom plate 110, so that the matching part between the floor and the drain pipe 120 can be sealed to avoid foaming and overflowing.

[0045] When the drain assembly 100 is in use, the first open end 121 of the drain pipe 120 is passed through the prefabricated hole on the inner tank and the installation hole 111 on the bottom plate 110 in sequence, and the elastomer 130 is elastically deformed to abut against the side of the bottom plate 110 facing the first open end 121, and the stopper 140 abuts against the side of the bottom plate 110 facing the second open end 122, so that the drain pipe 120 and the bottom plate 110 are fixed through the cooperation between the elastomer 130 and the stopper 140, and the sealing of the cooperation between the drain pipe 120 and the bottom plate 110 is achieved to avoid shrinkage and overflow.

[0046] Compared with the related art which uses a sponge to wrap around the drain pipe 120 to seal the fitting between the drain pipe 120 and the bottom plate 110, the drain assembly 100 provided by the utility model fixes and seals the drain pipe 120 and the bottom plate 110 through the fitting between the elastic body 130 and the stopper 140, simplifies the operation of wrapping the drain pipe 120 with a sponge, improves the installation efficiency of the drain pipe 120, and reduces the cost. In addition, the drain assembly 100 provided by the utility model has a simple structure, is easy to process, is firmly and reliably installed, and has a good sealing effect.

[0047] like Figure 5 As shown, in some embodiments, in order to improve the structural strength of the base plate 110, the base plate 110 includes a mounting portion and a boss 113 protruding from the mounting portion toward the second open end 122, the boss 113 includes a flat portion 113a and an inclined portion 113b, the inclined portion 113b is connected between the mounting portion and the flat portion 113a, and the mounting hole 111 is set in the flat portion 113a.

[0048] It should be noted that the inclined portion 113b of the boss 113 can provide support for the bottom plate 110 and disperse the external pressure on the bottom plate 110, thereby increasing the stability and bearing capacity of the bottom plate 110 and reducing deformation. The flat portion 113a is used to reserve space for installing the drain pipe 120 so that the defrost water can be discharged smoothly.

[0049] See also Figure 6 and Figure 7 In some embodiments, in order to facilitate the elastic body 130 to pass through the mounting hole 111 of the bottom plate 110, the outer wall of the elastic body 130 is inclined relative to the outer wall of the drain pipe 120 in the direction from the first end 131 to the second end 132. This is equivalent to the outer wall of the elastic body 130 gradually expanding outward from the first end 131 to the second end 132, so that the elastic body 130 can be guided to pass through the mounting hole 111 of the bottom plate 110 smoothly by using the inclined side wall of the elastic body 130.

[0050] It should be noted that the elastic body 130 can be provided as one or more. When the elastic body 130 is provided as one, the elastic body 130 can be provided in an umbrella-shaped sleeve on the outer wall of the drain pipe 120. When the elastic body 130 is provided as more than one, the elastic body 130 can be provided as a plurality of elastic buckles, and the plurality of elastic bodies 130 are fixedly provided on the outer wall of the drain pipe 120 along the circumference of the drain pipe 120.

[0051] At the same time, in order to facilitate the elastic body 130 to pass through the mounting hole 111 of the bottom plate 110, the outer wall of the elastic body 130 can also be set as an inclined surface or a curved surface. When the outer wall of the elastic body 130 is set as a curved surface, the curved surface can be a curved convex surface protruding relative to the elastic body 130, or a curved concave surface recessed relative to the elastic body 130.

[0052] like Figure 6 As shown, in some embodiments, in order to further improve the sealing between the drain pipe 120 and the bottom plate 110, the drain assembly 100 also includes a sealing layer 150 arranged between the stop body 140 and the bottom plate 110, and the sealing layer 150 is fixed to the side of the stop body 140 facing the elastomer 130.

[0053] It should be noted that the sealing layer 150 can be set as a foam layer. When the elastomer 130 abuts against the base plate 110, the sealing layer 150 is clamped between the stopper 140 and the base plate 110 to further seal the gap between the base plate 110 and the stopper 140 to prevent foaming and overflow.

[0054] At the same time, the thickness of the sealing layer 150 can be slightly greater than the distance between the stopper 140 and the bottom plate 110 to improve the sealing effect. Optionally, when the distance between the stopper 140 and the bottom plate 110 is 3 mm, the thickness of the sealing layer 150 can be 2 mm to 3 mm greater than the distance between the stopper 140 and the bottom plate 110. Optionally, the thickness of the sealing layer 150 is 5 mm.

[0055] like Figure 6 As shown, in some embodiments, in order to further improve the sealing performance between the drain pipe 120 and the bottom plate 110, an adhesive layer 160 is provided on the side of the sealing layer 150 facing the bottom plate 110 to avoid a gap between the sealing layer 150 and the bottom plate 110. The adhesiveness of the adhesive layer 160 is used to make up for the gap formed by the loose squeezing of the sealing layer 150 and the bottom plate 110, further preventing foaming and overflowing.

[0056] Optionally, the adhesive layer 160 and the sealing layer 150 may be provided as an integral structure. For example, double-sided adhesive foam may be used as the sealing layer 150 , and the adhesive layers on both sides of the double-sided adhesive foam are respectively fixed to the bottom plate 110 and the stopper 140 .

[0057] like Figure 7 As shown ( Figure 7 The sealing layer 150 and the adhesive layer 160 are not shown). In some embodiments, in order to improve the connection stability between the elastic body 130 and the bottom plate 110, the mounting hole 111 is provided with a flange 112 extending toward the first open end 121. After the first open end 121 of the drain pipe 120 is inserted into the mounting hole 111, the flange 112 is placed between the second end 132 of the elastic body 130 and the outer wall of the drain pipe 120, so that the second end 132 is buckled with the flange 112. That is, after the elastic body 130 passes through the mounting hole 111, the elastic body 130 recovers its deformation and is just clamped with the flange 112, forming an undercut between the bottom plate 110 and the drain pipe 120, thereby improving the connection stability.

[0058] It should be noted that, at the same time, since the bottom plate 110 is relatively thin (the bottom plate 110 is usually a thin iron with a thickness of 0.27 mm), when the drain pipe 120 is inserted into the mounting hole 111, due to the extrusion pressure between the elastomer 130 and the side wall of the mounting hole 111, it is easy to cause the bottom plate 110 to be recessed toward the first opening end 121. The utility model utilizes the flange 112 to increase the structural strength of the side wall of the mounting hole 111, and at the same time can utilize the flange 112 to guide the elastomer 130 to pass through the mounting hole 111 to avoid deformation of the bottom plate 110.

[0059] In addition, the flange 112 can also increase the contact area between the mounting hole 111 of the bottom plate 110 and the elastic body 130, so as to prevent the thin bottom plate 110 from cutting off the elastic body 130 when the mounting hole 111 and the elastic body 130 are squeezed. Moreover, a gap is provided between the second end 132 of the elastic body 130 and the outer wall of the drain pipe 120, so that the elastic body 130 can be close to the outer wall of the drain pipe 120 when squeezed, so as to prevent excessive squeezing between the elastic body 130 and the bottom plate 110.

[0060] See also Figure 7 In some embodiments, in order to facilitate the guidance of the generated defrost water, the axial direction of the drain pipe 120 intersects with the axial direction of the mounting hole 111. It should be noted that the drain pipe 120 is connected between the bottom plate 110 and the evaporating dish, and the defrost water can flow naturally into the evaporating dish by using the inclination angle of the drain pipe 120. At the same time, the installation space in the refrigerator is limited, and the inclination angle of the drain pipe 120 can take into account the compactness of the space.

[0061] In some embodiments, in order to collect the defrost water, the drain assembly 100 further includes a water collection tank 170 connected to the second open end 122 of the drain pipe 120 , and the side wall of the water collection tank 170 is inclined from the outer edge of the water collection tank 170 to the second open end 122 .

[0062] It should be noted that, when the first open end 121 of the drain pipe 120 is inserted into the mounting hole 111, the water collecting tank 170 at the second open end 122 of the drain pipe 120 can abut against the inner tank of the refrigerator, sealing the gap between the drain pipe 120 and the inner tank of the refrigerator. In addition, the side wall of the water collecting tank 170 can fit the inner tank of the refrigerator, thereby guiding the defrost water into the drain pipe 120 for discharge.

[0063] In some embodiments, in order to prevent foreign objects in the refrigerator from falling into the drain pipe 120 , a blocking net is further provided at the open end of the drain pipe 120 .

[0064] It should be understood that the present invention is not limited to the precise structure described above and shown in the drawings, and various modifications and changes can be made without departing from the scope thereof. The scope of the present invention is limited only by the appended claims.

[0065] In addition, the technical solutions of the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.
