Description

Technical Field

[0001] This utility model relates to the field of refrigerator drainage technology, specifically a refrigerator drainage component and a refrigerator. Background Technology

[0002] The refrigerator drainage system is an important part of the refrigerator, mainly used to handle the defrost water produced inside the refrigerator, ensuring that the inside of the refrigerator remains dry and clean.

[0003] The existing drainage system works by draining defrost water into a drip tray through a drain pipe connected to the refrigeration compartment. Because of the connection of the drain pipe, hot and humid air from outside will enter the refrigerator through the drain pipe, causing the temperature inside the refrigerator to rise and increasing the refrigerator's energy consumption. In addition, the hot and humid air from outside will come into contact with the low-temperature evaporator, which can easily cause frost and ice to form on the surface of the evaporator, resulting in a reduction in the evaporator's cooling effect. Utility Model Content

[0004] The purpose of this invention is to provide a refrigerator drainage component and a refrigerator, which solves the problem mentioned in the background art of external hot and humid air entering the refrigerator through the drain pipe.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a refrigerator drainage component, comprising a water collection hopper and a water receiving basin. The bottom of the water collection hopper is connected to an upper drain pipe and a transition pipe located below the upper drain pipe. Inside the transition pipe is a float ball, with an upper connecting pipe at the top connected to the upper drain pipe and a lower connecting pipe at the bottom connected to the lower drain pipe. A water receiving basin is located below the lower drain pipe. When the pressure difference between the inside and outside of the refrigerator is small, the float ball can block the lower connecting pipe. When the pressure difference is large, the float ball moves upward to block the upper connecting pipe, preventing hot and humid air from entering the refrigerator. A second float ball, located below the lower drain pipe, blocks the lower drain pipe to prevent excessive defrost water from overflowing from the water receiving basin.

[0007] Furthermore, a cage is fixedly installed on the top surface of the water receiving basin, the second float is installed inside the cage, the lower drain pipe passes through the top plate of the cage and is connected to the connecting bucket, and the bottom end of the lower drain pipe is lower than the top surface of the water receiving basin.

[0008] Furthermore, the lower end sidewall of the drain pipe is connected to the overflow pipe, and the connection point is located above the cage. The portion of the overflow pipe near the drain pipe is inclined downwards.

[0009] Furthermore, the diameter of the float is larger than the inner diameter of the upper and lower drain pipes.

[0010] Furthermore, the water collecting hopper is equipped with a filter plate, and the outer wall of the filter plate is provided with a sealing sleeve that fits against the inner wall of the water collecting hopper.

[0011] Furthermore, the top surface of the filter plate is provided with a lifting block.

[0012] A refrigerator using the drainage assembly described above, wherein the water collection basin is connected to the refrigerator drain outlet, the water basin is disposed above the refrigerator compressor, and the overflow pipe extends through the side wall of the refrigerator to the outside of the refrigerator.

[0013] This utility model has the following beneficial effects:

[0014] When the pressure difference between the inside and outside of the refrigerator is small, the float will block the lower connecting pipe under the action of gravity. When the pressure difference between the inside and outside of the refrigerator is large, the float will rise under the action of pressure and block the upper connecting pipe. This effectively prevents the hot and humid air from entering the refrigerator and flowing relative to the cold air inside the refrigerator, thereby improving the cooling effect of the refrigerator and reducing the power consumption of the refrigerator.

[0015] When the water level in the water basin is high, the float ball 2 floats above the water surface and blocks the drain pipe, preventing defrost water from continuing to flow into the water basin and preventing excessive defrost water from overflowing into the compressor compartment and causing a short circuit.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Please see Figure 1-5 As shown, this utility model is a refrigerator drainage component, including a water collection hopper 1 and a water receiving basin 8. The bottom end of the water collection hopper 1 is connected to an upper drain pipe 2 and a transition pipe 3, which is located below the upper drain pipe 2. A float ball 4 is installed inside the water collection hopper 1. The top end is provided with an upper connecting pipe 301 connected to the upper drain pipe 2, and the bottom end is provided with a lower connecting pipe 302 connected to the lower drain pipe 5. The water receiving basin 8 is located below the lower drain pipe 5. When the pressure difference between the inside and outside of the refrigerator is small, the float ball 4 can block the lower connecting pipe 302. When the pressure difference between the inside and outside of the refrigerator is large, the float ball 4 moves upward to block the upper connecting pipe 301, preventing hot and humid air from entering the refrigerator. The second float ball 7 is located below the lower drain pipe 5 and blocks the lower drain pipe 5 to prevent excessive defrost water from overflowing in the water receiving basin 8.

[0028] This embodiment provides a refrigerator drainage component. When the pressure difference between the inside and outside of the refrigerator is small, float 4 blocks the lower connecting pipe 302 under the action of gravity. When the pressure difference between the inside and outside of the refrigerator is large, float 4 moves upward under the action of pressure and blocks the upper connecting pipe 301, preventing outside air and cold air generated by the refrigerator from flowing in the drainage component, preventing hot and humid air from entering the refrigerator compartment and increasing refrigerator energy consumption, and ensuring the refrigerator's cooling effect. The water basin 8 is used to collect defrost water. The water basin 8 is located above the compressor. When the compressor is working, it generates heat to accelerate the evaporation of defrost water in the water basin 8. Float 7 floats above the water surface in the water basin 8. When the amount of defrost water is large, float 7 will block the outlet at the bottom of the lower drain pipe 5 to prevent defrost water in the water basin 8 from overflowing into the compressor compartment, which could cause water accumulation in the compressor compartment and potentially lead to a short circuit.

[0029] The water receiving basin 8 is fixedly equipped with a cage 6 on its top surface. The float 7 is placed inside the cage 6. The drain pipe 5 passes through the top plate of the cage 6 and is connected to the connecting bucket 501. The bottom end of the drain pipe 5 is lower than the top surface of the water receiving basin 8. The cage 6 limits the float 7 so that the float 7 can only float inside the cage 6. The bottom end of the drain pipe 5 is lower than the top surface of the water receiving basin 8 to ensure that the float 7 will block the drain pipe 5 before the water overflows.

[0030] The lower end of the drain pipe 5 is connected to the overflow pipe 9, and the connection point is located above the cage 6. The portion of the overflow pipe 9 near the drain pipe 5 is inclined downwards. After the float 7 blocks the drain pipe 5, the subsequent defrosting water will enter the overflow pipe 9 to prevent defrosting water from accumulating in the refrigeration chamber. The outlet of the overflow pipe 9 is located outside the refrigerator, and the user can place a water basin at the outlet of the overflow pipe 9 to collect the water.

[0031] The diameter of the float 4 is larger than the inner diameter of the upper drain pipe 2 and the lower drain pipe 5.

[0032] The water collection hopper 1 is equipped with a filter plate 10. The outer wall of the filter plate 10 is provided with a sealing sleeve 1001 that fits against the inner wall of the water collection hopper 1. The defrost water is filtered by the filter plate 10 to prevent impurities in the defrost water from entering the drainage component and causing blockage of the drainage component. The filter plate 10 can be removed from the water collection hopper 1 for cleaning.

[0033] The filter plate 10 is provided with a lifting block 1002 on its top surface, which allows the filter plate 10 to be easily pulled out.

[0034] A refrigerator uses a drainage assembly as described above, wherein the water collection hopper 1 is connected to the refrigerator drain outlet, the water receiving basin 8 is disposed above the refrigerator compressor, and the overflow pipe 9 extends through the side wall of the refrigerator to the outside of the refrigerator.

[0035] Understandably, this utility model can block the drainage component to prevent the convection between the hot and humid air outside and the cold air generated by the refrigerator, thus ensuring the refrigeration effect of the refrigerator. Secondly, it can prevent the water basin 8 from accumulating excessive defrost water, which could cause the defrost water to overflow into the compressor chamber and lead to water accumulation and short circuit in the compressor chamber.

[0036] A specific application of the operation process in this embodiment is as follows: When the pressure difference between the inside and outside of the refrigerator is small, the defrost water flows from the water collection trough 1 through the upper drain pipe 2 and the upper connecting pipe 301 into the transition pipe 3. The float ball 4 floats up under the buoyancy of the water, allowing the defrost water to enter the lower connecting pipe 302 and then through the lower drain pipe 5 into the water collection basin 8. After the defrost water has drained, the float ball 4 blocks the lower connecting pipe 302 under the action of gravity, preventing hot and humid air from entering the refrigerator compartment. When the pressure difference between the inside and outside of the refrigerator is large, the pressure difference pushes the float ball 4 up, causing it to... 4. Block the upper connecting pipe 301 to prevent hot and humid air from entering the refrigerator compartment. After opening the refrigerator door, the pressure difference between the inside and outside of the refrigerator is the same. Then, drain the defrost water. After the defrost water enters the water basin 8, it will cause the float ball 2 7 to float. If the defrost water volume exceeds the capacity of the water basin 8, the float ball 2 7 will block the outlet of the lower drain pipe 5 before all the defrost water enters the water basin 8, preventing the defrost water from continuing to drain into the water basin 8 and preventing the defrost water in the water basin 8 from overflowing into the compressor compartment and causing water accumulation in the compressor compartment and short circuit. Excess defrost water is discharged to the outside of the refrigerator through the overflow pipe 9.
