Abstract
Description
Technical Field
[0001] This application relates to the field of refrigeration equipment, and in particular to a box liner assembly and refrigeration equipment. Background Technology
[0002] There is usually a drain pipe inside the refrigerator. The connector at the top of the drain pipe is connected to the connecting pipe at the bottom of the refrigerator compartment. The end of the drain pipe extends to the drip tray. The main function of the drain pipe is to drain the condensate that adheres to the inner wall of the refrigerator compartment, thereby keeping the inside of the compartment dry and clean.
[0003] Because the outer diameter of the connecting pipe at the bottom of the refrigerator liner is small, while the inner diameter of the matching pipe fitting is large, there is a large gap between the two. When foaming liquid is injected between the refrigerator liner and the refrigerator shell, the foaming liquid will seep into the gap between the connecting pipe and the pipe fitting under the action of the high-pressure gun and enter the drain pipe, causing blockage and other problems. This will cause condensate to accumulate in the drain pipe, which will lead to bacterial growth and other problems, and even affect the normal operation of the refrigerator, seriously affecting the user experience. Utility Model Content
[0004] Based on this, embodiments of this application provide a box liner assembly and a refrigeration device.
[0005] In a first aspect, embodiments of this application provide a box liner assembly, including:
[0006] The container liner includes a container liner body and a connecting pipe. The connecting pipe is disposed on the outside of the container liner body and connected to the container liner body. The container liner body has a drain outlet, and the connecting pipe communicates with the drain outlet.
[0007] The pipe fitting includes a pipe fitting body, a first pipe segment, and a second pipe segment connected in sequence. The first pipe segment and the second pipe segment are respectively disposed on both sides of the pipe fitting body and are both connected to the pipe fitting body. The first pipe segment is sleeved on the outer periphery of the connecting pipe, and a sealing ring is provided between the first pipe segment and the connecting pipe.
[0008] In some embodiments, the area of the cross-section enclosed by the inner wall of the pipe joint is the inner cross-sectional area, and the inner cross-sectional area of the first pipe segment gradually decreases in the direction from the pipe joint to the liner body.
[0009] In some embodiments, the inner cross-sectional area of the first pipe segment remains constant in the direction from the pipe joint to the liner body.
[0010] In some embodiments, the pipe fitting and the sealing ring are interference fit; and / or,
[0011] The sealing ring and the connecting pipe are connected by adhesive.
[0012] In some embodiments, the pipe fitting further includes a support portion, the support portion being disposed around the first pipe segment and connected to one end of the first pipe segment opposite to the pipe fitting body, the support portion being disposed in contact with the outer surface of the box liner body; and / or
[0013] The outer cross-sectional area of the second pipe section is smaller than the outer cross-sectional area of the pipe joint body.
[0014] In some embodiments, the tank liner assembly further includes a drain pipe, and a second section of the pipe fitting is connected to the drain pipe; and / or,
[0015] The sealing ring is made of foam material.
[0016] In some embodiments, the tank liner assembly further includes a water collection tray disposed at one end of the drain pipe opposite to the tank liner; and / or,
[0017] The sealing ring is a foamed EPDM rubber component.
[0018] Secondly, embodiments of this application also provide a refrigeration device, including the box liner assembly as described above.
[0019] In some embodiments, the refrigeration equipment further includes a housing, and the liner assembly is disposed within the housing.
[0020] In some embodiments, an insulation layer is provided between the outer shell and the inner body of the box.
[0021] The refrigerator liner assembly provided in this application embodiment, by setting a sealing ring between the pipe joint and the connecting pipe, can fill the gap between the pipe joint and the connecting pipe, so that the pipe joint and the connecting pipe are sealed together. Therefore, when foaming liquid is injected between the refrigerator liner and the refrigerator shell, the foaming liquid cannot enter the gap between the connecting pipe and the pipe joint due to the blocking effect of the sealing ring, and therefore cannot enter the drain pipe connected to the pipe joint. This can avoid the problem of the drain pipe being blocked by foaming liquid, improve the quality of the refrigerator, and thus improve the user experience. Attached Figure Description

[0036] Please see Figure 1 , Figure 2 and Figure 3 This application provides a box liner assembly 100, including a box liner 10 and a pipe connector 20.
[0037] Please see Figure 4 , Figure 5 and Figure 6 The liner 10 includes a liner body 11 and a connecting pipe 12. The connecting pipe 12 is disposed on the outside of the liner body 11 and connected to the liner body 11. The liner body 11 has a drain outlet 15, and the connecting pipe 12 is connected to the drain outlet 15.
[0038] Please see Figure 3 The pipe joint 20 includes a pipe joint body 23, a first pipe section 21, and a second pipe section 22 connected in sequence. The first pipe section 21 and the second pipe section 22 are respectively disposed on both sides of the pipe joint body 23 and are both connected to the pipe joint body 23. The first pipe section 21 is sleeved on the outer periphery of the connecting pipe 12, and a sealing ring 30 is provided between the first pipe section 21 and the connecting pipe 12.
[0039] For example, the inner container 10 can be a refrigerator inner container or a freezer inner container.
[0040] Understandably, the above-mentioned drainage structure (connecting pipe 12 and pipe joint 20) can not only be used to drain the condensate on the inner wall of the refrigerator liner 10, but also to drain the defrost water produced when the evaporator defrosts, so as to avoid the growth of bacteria in the refrigerator and cause food spoilage.
[0041] The refrigerator liner assembly 100 provided in this application embodiment, by setting a sealing ring 30 between the pipe joint 20 and the connecting pipe 12, can fill the gap between the pipe joint 20 and the connecting pipe 12, so that the pipe joint 20 and the connecting pipe 12 are sealed together. Therefore, when foaming liquid is injected between the refrigerator liner 10 and the refrigerator shell, the foaming liquid cannot enter the gap between the connecting pipe 12 and the pipe joint 20 due to the blocking effect of the sealing ring 30, and therefore cannot enter the drain pipe connected to the pipe joint 20. This can avoid the problem of the drain pipe being blocked by foaming liquid, improve the quality of the refrigerator, and thus improve the user experience.
[0042] Please see Figure 3 and Figure 6 The pipe connector 20 also includes a support portion 24, which is arranged around the first pipe section 21 and connected to the end of the first pipe section 21 away from the pipe connector body 23. The support portion 24 is arranged to fit against the outer surface of the box body 11.
[0043] It is understandable that by providing a support 24 at one end of the pipe joint 20, since the support 24 surrounds the first pipe section 21 and fits the tank body 11, the foaming liquid is difficult to seep in from the gap between the support 24 and the tank body 11. In other words, by providing the support 24, the foaming liquid can be further isolated from the pipe joint 20, thereby further reducing the possibility of the foaming liquid seeping into the connection pipe 12 and the pipe joint 20.
[0044] Please see Figure 3 The outer cross-sectional area (area of the cross-section enclosed by the outer wall) of the second pipe section 22 is smaller than the outer cross-sectional area of the pipe connector body 23. That is to say, the outer cross-sectional area of the pipe connector body 23 is larger, so that the pipe connector body 23 has a certain water storage capacity. When the water flow is obstructed or even blocked by the pipe connector 20 or the drain pipe connected to the pipe connector 20, the pipe connector body 23 can also temporarily store a part of the water to prevent the water from overflowing into the tank liner 10.
[0045] In some embodiments, the area of the cross-section enclosed by the inner wall of the pipe joint 20 is the inner cross-sectional area, and the inner cross-sectional area of the first pipe section 21 gradually decreases in the direction from the pipe joint 20 to the liner body 11.
[0046] For example, the inner cross-section (the cross-section enclosed by the inner wall) of the first pipe section 21 is circular, that is, the inner diameter of the first pipe section 21 gradually decreases in the direction from the pipe joint 20 to the box body 11.
[0047] Understandably, by setting the inner cross-sectional area of the first pipe section 21 to gradually decrease, that is, the inner cross-sectional area of the pipe joint 20 is smaller the closer it is to the tank body 11, the smaller the gap between the pipe joint 20 and the connecting pipe 12 becomes, and thus the sealing performance between the pipe joint 20 and the connecting pipe 12 becomes better. The sealing performance between the pipe joint 20 and the connecting pipe 12 is best at the point on the pipe joint 20 closest to the tank body 11. This position is also the top of the pipe joint 20. That is to say, the seepage of foaming liquid can be prevented from the top of the pipe joint 20, thus avoiding the pipe joint 20 from being blocked.
[0048] In some other embodiments, the inner cross-sectional area of the first pipe segment 21 remains constant in the direction from the pipe joint 20 to the liner body 11.
[0049] It is understandable that when the inner cross-sectional area of the first pipe segment 21 is greater than the outer cross-sectional area (the cross-section enclosed by the outer wall) of the sealing ring 30 in its initial state (non-compression state), even if the inner cross-sectional area of the first pipe segment 21 remains uniform in its extension direction, a sealed connection between the pipe joint 20 and the connecting pipe 12 can still be achieved.
[0050] When the inner cross-section (the cross-section enclosed by the inner wall) of the first pipe section 21 is circular, that is to say, the inner diameter of the first pipe section 21 remains unchanged in the direction from the pipe joint 20 to the box body 11.
[0051] For example, the pipe fitting 20 and the sealing ring 30 are interference fit.
[0052] It is understood that when the sealing ring 30 and the pipe joint 20 are in an interference fit, it means that the inner diameter of the pipe joint 20 is larger than the outer diameter of the sealing ring 30 (initial state), so that the sealing ring 30 is in a compressed state, and the outer surface of the sealing ring 30 is tightly fitted with the inner surface of the pipe joint 20, thereby achieving a sealed connection between the sealing ring 30 and the pipe joint 20.
[0053] For example, the liner assembly 100 also includes a drain pipe (not shown), and the second pipe section 22 of the pipe connector 20 is connected to the drain pipe.
[0054] For example, the tank liner assembly 100 further includes a water receiving tray (not shown) disposed at one end of the drain pipe away from the tank liner 10.
[0055] For example, the sealing ring 30 is made of foam material.
[0056] In some embodiments, the sealing ring 30 is an EPDM (Ethylene Propylene Diene Monomer) foam.
[0057] In some embodiments, the sealing ring 30 and the connecting pipe 12 can be connected by adhesive to fix the sealing ring 30 and prevent the sealing ring 30 from shaking during the assembly of the pipe joint 20 and the connecting pipe 12, which would affect the sealing effect.
[0058] This application also provides a refrigeration device, including the liner assembly 100 in any of the above embodiments.
[0059] For example, the refrigeration equipment also includes a housing, and the liner assembly 100 is disposed inside the housing.
[0060] For example, an insulation layer is provided between the outer shell and the inner body 11. For example, the insulation layer is made of foam material.
[0061] For example, the refrigeration equipment can be a refrigerator, freezer, beverage cooler, wine cooler, freezer box, ice cream machine, ice maker, etc. When the refrigeration equipment is a refrigerator, the refrigerator can be a direct-cooling refrigerator, a frost-free refrigerator, or a hybrid refrigerator.
[0062] The box liner assembly and refrigeration equipment provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application, and the descriptions of the embodiments above are only for the purpose of helping to understand this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
