Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, and in particular to a drainage assembly for a refrigerator and a refrigerator. Background Art

[0002] As the functions of refrigerators continue to increase, more and more components are installed in the compressor compartment, and the operating space is getting smaller and smaller, making the installation of the drain pipe more and more difficult. When a cooling fan is installed at the bottom of the refrigerator, the gap between the compressor and the cooling fan is small, and the condenser pipe in the compressor compartment along the direction from the compressor to the cooling fan will block the installation of the drain pipe. At present, most refrigerator drain pipes are installed last after the compressor pipe welding (welding condenser pipe) is completed. In this way, for refrigerators with small installation space, it is extremely difficult to operate and it is easy to scratch your hands.

[0003] The related art discloses a refrigerator drain pipe assembly, including an internal drain pipe assembly and an external drain pipe assembly. The internal drain pipe assembly includes a refrigerating chamber drain pipe, a freezing chamber drain pipe and a connecting piece. The connecting piece includes a tube body, one end of which is connected to the refrigerating chamber drain pipe, the other end of which is fixed to the inclined plate of the refrigerator and communicated with the external drain pipe assembly, and the tube body is also provided with a branch pipe connected to the freezing chamber drain pipe. The external drain pipe assembly includes a drain pipe body, a water receiving tray and a fan bracket. The inlet position of the drain pipe body coincides with the outlet position of the connecting piece, the outlet of the drain pipe body is located above the water receiving position of the water receiving tray, and the drain pipe body is integrated on the fan bracket, and the fan bracket is fixed on the water receiving tray.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] The related technology integrates the drain pipe body on the fan bracket. Although it can reduce the space occupied by the compressor compartment and solve the problem that the drain pipe is difficult to install due to the small space in the compressor compartment, the fan vibrates continuously during operation, which will drive the fan bracket to vibrate, thereby causing the external drain pipe to vibrate, and the water in the external drain pipe will fall out of the water collection tray. Moreover, the connection between the internal drain pipe and the external drain pipe is easy to loosen or even detach, causing damage to the components in the compressor compartment.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0045] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0046] Combination Figure 1-3 As shown, the embodiment of the present disclosure provides a drainage assembly for a refrigerator 80, including an external drainage pipe 10 and an evaporation dish 20. The external drainage pipe 10 includes a pipe body 12 and a first connecting portion 11 provided on the pipe body 12, and the evaporation dish 20 includes a first matching portion 21, and the first connecting portion 11 is connected to the first matching portion 21, so that the external drainage pipe 10 is integrated on the evaporation dish 20.

[0047] By using the drainage assembly for the refrigerator 80 provided by the embodiment of the present disclosure, the external drainage pipe 10 is integrated on the evaporation dish 20 through the first matching portion 21 and the first connecting portion 11, and is installed on the box body 81 together with the bottom cooling assembly. It is not necessary to install the external drainage pipe 10 after the compressor 82 is welded with the condenser pipe 85, which reduces the requirements for the operating space, reduces the impact of the small space of the compressor compartment 30 on the installation of the external drainage pipe 10, reduces the assembly difficulty, and improves the assembly speed. In addition, the external drainage pipe 10 is integrated on the evaporation dish 20 to avoid the problem in the related art that the external drainage pipe 10 vibrates due to the continuous vibration of the fan during operation, thereby causing the water in the external drainage pipe 10 to fall outside the water receiving tray, and the connection between the internal drainage pipe 40 and the external drainage pipe 10 is loosened or even disconnected due to vibration, causing damage to the components in the compressor compartment 30.

[0048] It is understandable that the refrigerator 80 includes a cooling fan 84, a compressor 82, a condenser 83 and a support plate 86, the support plate 86 is arranged at the bottom end of the compressor compartment 30, and the evaporating dish 20, the cooling fan 84, the condenser 83 and the compressor 82 are all assembled on the support plate 86 to form a bottom cooling assembly for distribution. In the embodiment of the present disclosure, the external drain pipe 10 is integrated on the evaporating dish 20, that is, the bottom cooling assembly of the embodiment of the present disclosure includes the external drain pipe 10, the evaporating dish 20, the cooling fan 84, the condenser 83 and the compressor 82.

[0049] Optionally, the first connecting portion 11 is sleeved on the outer surface of the tube body 12 .

[0050] In this way, the first connecting portion 11 is sleeved on the outer surface of the tube body 12, and the displacement of the tube body 12 in the XY plane is limited by the first connecting portion 11. Figure 3 shown.

[0051] Combination Figure 4 and Figure 6 As shown, currently, the surface of the evaporating dish 20 facing the tube body 12 is provided with a protrusion 22, and the tube body 12 is sleeved on the outer surface of the protrusion 22 with a gap. In this way, the stability of the tube body 12 is further improved through the cooperation between the protrusion 22 and the tube body 12.

[0052] Optionally, a gap is left between the bottom end of the tube body 12 and the bottom plate 23 of the evaporating dish 20 .

[0053] In this way, a gap is left between the bottom end of the tube body 12 and the bottom plate 23 of the evaporating dish 20 , which facilitates the water in the tube body 12 to flow smoothly and quickly into the evaporating dish 20 .

[0054] Optionally, the first connecting portion 11 and the first matching portion 21 are fixedly connected.

[0055] Optionally, the first connecting portion 11 is connected to the first matching portion 21 by means of screws.

[0056] In this way, the first connecting portion 11 is fixed to the first matching portion 21 by screws, so that the external drain pipe 10 is integrated on the evaporating dish 20. Moreover, when the external drain pipe 10 or other parts need to be replaced, they can be quickly disassembled to facilitate subsequent maintenance and replacement.

[0057] Optionally, the first connecting portion 11 and the first matching portion 21 are welded.

[0058] In this way, the first connecting portion 11 is fixed to the first matching portion 21 by welding, so that the external drain pipe 10 is integrated on the evaporating dish 20, and the structure of the connection is relatively stable.

[0059] Optionally, the drainage assembly further includes an internal drainage pipe 40. One end of the internal drainage pipe 40 is suitable for being connected to the water outlet 51 of the inner tank 50 of the refrigerator 80, and the other end is connected to the external drainage pipe 10. The external drainage pipe 10 further includes a second connecting portion 13, and the internal drainage pipe 40 includes a second matching portion 41. Both the second connecting portion 13 and the second matching portion 41 are hollow in design. The second connecting portion 13 is sleeved on the outer surface of the second matching portion 41, such as Figure 5 As shown, the second matching portion 41 is sleeved on the outer surface of the second connecting portion 13 .

[0060] In this way, the internal drain pipe 40 and the external drain pipe 10 are connected together by the cooperation of the second connecting portion 13 and the second matching portion 41, and are used together for drainage. During the assembly process of the bottom cooling assembly and the box body 81, the external drain pipe 10 and the internal drain pipe 40 can be assembled first, and then the condenser pipe 85 can be welded, which reduces the requirements for the operating space for installing the external drain pipe 10, reduces the difficulty of assembly, and improves the assembly speed. It can be understood that the water generated when the refrigerator 80 is working flows into the internal drain pipe 40 through the inner tank 50, flows into the evaporating dish 20 through the external drain pipe 10, and the condenser pipe 85 evaporates the water vapor through the evaporating dish 20, and the cooling fan 84 blows air to disperse the water vapor and cool the compressor 82.

[0061] Optionally, the internal drain pipe 40 and / or the external drain pipe 10 are arranged at an incline.

[0062] In this way, water can flow smoothly into the drainage assembly along the water outlet 51 .

[0063] Optionally, the drainage assembly further includes a sealing ring 60. The sealing ring 60 is disposed between the second connecting portion 13 and the second matching portion 41, and is used for sealing between the second connecting portion 13 and the second matching portion 41.

[0064] In this way, a sealing ring 60 is provided between the second connecting portion 13 and the second matching portion 41 to enhance the sealing effect of the connection and reduce liquid leakage.

[0065] Optionally, the sealing ring 60 is a sponge.

[0066] The sponge has good water absorption. When the sponge is arranged between the second connecting portion 13 and the second matching portion 41, the infiltrated liquid can be quickly absorbed when there is leakage at the connection. The sponge also has excellent elasticity. When the sponge is arranged between the second connecting portion 13 and the second matching portion 41, the assembly between the second connecting portion 13 and the second matching portion 41 is facilitated. In addition, the sponge is cheap, which can save costs.

[0067] Optionally, the sealing ring 60 is a waterproof tape.

[0068] The waterproof tape, also called raw tape, is made of polytetrafluoroethylene as raw material. The waterproof tape has strong sealing and waterproof properties. Therefore, by wrapping the waterproof tape around the outer surface of the second connecting portion 13 or the second matching portion 41, a better sealing effect can be achieved. Moreover, the number of turns of the waterproof tape can be adjusted according to the gap between the second connecting portion 13 and the second matching portion 41 to achieve a better sealing effect. In addition, the waterproof tape is cheap, which can save costs.

[0069] Alternatively, if Figure 5 As shown, when the second connecting portion 13 is sleeved on the outer surface of the second matching portion 41 , the outer surface of the second matching portion 41 and / or the inner surface of the second connecting portion 13 are provided with a first protrusion 42 , and the first protrusion 42 abuts against the sealing ring 60 .

[0070] When the second connection part 13 is sleeved on the outer surface of the second matching part 41, the outer surface of the second matching part 41 is provided with a first protrusion 42, and the first protrusion 42 cooperates with the inner wall surface of the sealing ring 60 to prevent the sealing ring 60 from moving. When the second connection part 13 is sleeved on the outer surface of the second matching part 41, the inner surface of the second connection part 13 is provided with a first protrusion 42, and the first protrusion 42 cooperates with the outer wall surface of the sealing ring 60 to prevent the sealing ring 60 from moving.

[0071] Optionally, there are multiple first protrusions 42 , and the multiple first protrusions 42 are sequentially arranged along the outer surface of the second matching portion 41 and / or the inner surface of the second connecting portion 13 .

[0072] In this way, the plurality of first protrusions 42 are in contact with and cooperate with the sealing ring 60, making it more difficult for the sealing ring 60 to move.

[0073] Optionally, when the second matching portion 41 is sleeved on the outer surface of the second connecting portion 13 , the outer surface of the second connecting portion 13 and / or the inner surface of the second matching portion 41 are provided with a second protrusion, and the second protrusion abuts against the sealing ring 60 .

[0074] When the second matching portion 41 is sleeved on the outer surface of the second connecting portion 13, a second protrusion is provided on the outer surface of the second connecting portion 13, and the second protrusion cooperates with the inner wall surface of the sealing ring 60 to prevent the sealing ring 60 from moving. When the second matching portion 41 is sleeved on the outer surface of the second connecting portion 13, a second protrusion is provided on the inner surface of the second matching portion 41, and the second protrusion cooperates with the outer wall surface of the sealing ring 60 to prevent the sealing ring 60 from moving.

[0075] Optionally, there are multiple second protrusions, and the multiple second protrusions are sequentially arranged along the outer surface of the second connecting portion 13 and / or the inner surface of the second matching portion 41 .

[0076] In this way, the plurality of second protrusions are in contact with and cooperate with the sealing ring 60, making it more difficult for the sealing ring 60 to move.

[0077] Optionally, when the second connecting portion 13 is sleeved on the outer surface of the second matching portion 41 , the section of the second connecting portion 13 that contacts the sealing ring 60 is inclined outward from bottom to top.

[0078] The section of the second connecting portion 13 that contacts the sealing ring 60 is set as a guiding inclined surface inclined outward, so that during the assembly of the second connecting portion 13 and the second matching portion 41 , the guiding sealing ring 60 is smoothly inserted between the second connecting portion 13 and the second matching portion 41 .

[0079] Optionally, when the second matching portion 41 is sleeved on the outer surface of the second connecting portion 13 , along the direction from bottom to top, the section of the second matching portion 41 that abuts against the sealing ring 60 is inclined inwardly.

[0080] The section of the second matching portion 41 that contacts the sealing ring 60 is set as an inwardly inclined guiding slope, so that during the assembly of the second connecting portion 13 and the second matching portion 41 , the sealing ring 60 is guided to be smoothly inserted between the second connecting portion 13 and the second matching portion 41 .

[0081] Combination Figure 1 and 2 As shown, the embodiment of the present disclosure provides a refrigerator 80, including a box body 81, an inner tank 50 and a drainage assembly for the refrigerator 80. The inner tank 50 is arranged in the box body 81, the inner tank 50 and the box body 81 together define a compressor compartment 30, and the drainage assembly for the refrigerator 80 is arranged in the compressor compartment 30.

[0082] Optionally, the refrigerator 80 further includes a compartment partition 70. The outer surface of the second matching portion 41 is further provided with a third protrusion 43, and the compartment partition 70 is provided with an abutment portion 71, which abuts against the third protrusion 43 to limit the second matching portion 41 from escaping from the compressor compartment 30.

[0083] In this way, the abutment cooperation between the abutment portion 71 and the third protrusion 43 limits the third protrusion 43 from continuing to move upward over the abutment portion 71 , thereby limiting the second matching portion 41 from continuing to move upward over the cabin partition 70 or even escaping from the compressor cabin 30 .

[0084] Optionally, there are multiple third protrusions 43 , and the multiple third protrusions 43 are sequentially arranged along the outer surface of the second matching portion 41 , and the multiple third protrusions 43 are all in abutment with the abutment portion 71 .

[0085] In this way, by abutting and cooperating with the abutting portion 71 , the second matching portion 41 can be better restricted from moving upward and escaping from the compressor compartment 30 .

[0086] Optionally, the bottom end of the second matching portion 41 abuts against the second connecting portion 13 to limit the second matching portion 41 from moving downward.

[0087] In this way, the second connecting portion 13 is abutted against the bottom end of the second matching portion 41 to restrict the second matching portion 41 from continuing to move downward over the second connecting portion 13 .

[0088] Optionally, the refrigerator 80 further includes a compartment partition 70. The top end of the second connecting portion 13 abuts against the compartment partition 70 to limit the second connecting portion 13 from continuing to move upward over the compartment partition 70.

[0089] In this way, the top end of the second connecting portion 13 is abutted against the compartment partition 70 of the refrigerator 80, so as to limit the second connecting portion 13 from continuing to move upward over the compartment partition 70. At the same time, the bottom end of the second matching portion 41 can also limit the second connecting portion 13 from moving upward.

[0090] Optionally, the second connecting portion 13 includes a first side wall 131 and a second side wall 132, the first side wall 131 abuts against the sealing ring 60, and the second side wall 132 abuts against the cabin partition 70. When the second connecting portion 13 is sleeved on the outer surface of the second matching portion 41, the first side wall 131 is inclined outward from the bottom to the top, and the top end of the second side wall 132 abuts against the cabin partition 70 vertically.

[0091] In this way, compared with the first side wall 131 directly abutting against the cabin partition 70, the provision of the second side wall 132 can increase the contact area with the abutting portion 71 of the cabin partition 70 and increase the stability of the abutting portion.
