Description

Technical Field

[0001] The present application relates to the technical field of household electrical appliances, for example, to a drainage structure for a refrigerator and the refrigerator. Background Art

[0002] At present, more and more users use refrigerators to store food and other items that need to be kept at low temperatures. During the use of the refrigerator, frost will form on the evaporator, resulting in a decrease in the refrigerator's refrigeration efficiency. Therefore, after the environmental conditions in the refrigerator meet the defrosting conditions, it is necessary to heat the frost on the evaporator to melt the frost and reduce the impact of the frost on the working efficiency of the evaporator. The defrost water formed by the melting of the frost will be discharged from the compressor compartment through the drain port of the refrigerator. Since the two ends of the drain pipe are connected to the compressor compartment and the external space respectively, the external air near the drain port encounters the cold air in the compressor compartment at the drain port, freezes when it encounters water, and causes the drain port to be blocked.

[0003] In the related art, a bellows is arranged at the drain outlet of the drain pipe, and the bellows is inserted into a water collecting box so that the water in the water collecting box forms a water seal at the drain outlet of the drain pipe, thereby isolating the compressor compartment from the outside air, reducing the heat exchange between the air in the compressor compartment and the outside air, and thereby reducing the problem of outside air freezing and clogging at the drain outlet.

[0004] In the publicly available implementation process, it was found that the relevant technology has at least the following problems:

[0005] Although the related technology can reduce the problem of ice blockage at the drain outlet, the water seal of the drain outlet makes the inner tank of the refrigerator a closed space. After the refrigerator door is opened, the high-temperature air from the outside enters the inner tank, causing the density of the gas in the inner tank to decrease. After the refrigerator door is closed, the inner tank is in a negative pressure state, that is, the compressor compartment is in a negative pressure state, and the gas in the external space connected to the drain pipe will enter the compressor compartment through the drain pipe. The gas will form bubbles in the water seal part, causing the bubble sound.

[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.

[0038] Combination Figures 1 to 5 As shown, the embodiment of the present disclosure provides a drainage structure for a refrigerator, including: a first storage element 10 and a second storage element 20. The first storage element 10 includes a first cavity 101. The height of the outlet of the first cavity 101 is lower than the height of the inlet of the first cavity 101. The second storage element 20 includes a second cavity 201. The inlet of the second cavity 201 is opened on the bottom wall of the second storage element 20. The height of the outlet of the second cavity 201 is higher than the height of the inlet of the second cavity 201. The height of the inlet of the second cavity 201 is lower than the height of the outlet of the first cavity 101. The outlet of the first cavity 101 is connected to the inlet of the second cavity 201. The inlet of the first cavity 101 is used to be connected to the press chamber. The outlet of the second cavity 201 is used to be connected to the external space.

[0039] The drainage structure for a refrigerator provided in the embodiment of the present disclosure is provided with a first storage element 10 and a second storage element 20, so that when the drainage structure is provided in the refrigerator, the defrosted water in the compressor chamber can be discharged. By limiting the inlet of the second cavity 201 to be opened on the bottom wall of the second storage element 20, and the height of the outlet of the second cavity 201 is higher than the height of the inlet of the second cavity 201, it is ensured that water is always stored in the second cavity 201, and the water seal at the water outlet of the drainage structure is achieved, and the outside air is reduced from entering the compressor chamber through the drainage device, and the problem of water molecules condensing at the drainage outlet when encountering cold and causing the drainage outlet to be blocked is reduced. In addition, when the refrigerator is under negative pressure, the air in the first cavity 101 is absorbed into the refrigerator to balance the negative pressure of the refrigerator, and reduce the bubble sound generated when the outside air enters the compressor chamber.

[0040] Specifically, by limiting the height of the outlet of the first cavity 101 to be lower than the height of the inlet of the first cavity 101, the water level in the first cavity 101 is limited to be lower than the height of the inlet of the first cavity 101 by the height of the outlet of the first cavity 101, thereby reducing the problem of defrost water in the first cavity 101 flowing back into the compressor chamber due to the height of the inlet of the first cavity 101 being lower than the height of the outlet of the first cavity 101.

[0041] Specifically, by limiting the height of the inlet of the second cavity 201 to be lower than the height of the outlet of the first cavity 101, the water in the second cavity 201 can be reduced from flowing out of the outlet of the second cavity 201 and into the first cavity 101 due to the height of the inlet of the second cavity 201 being higher than the height of the outlet of the first cavity 101, thereby reducing the backflow of defrost water, reducing the impact on the pressure in the refrigerator, and improving the practicality of the drainage structure.

[0042] Specifically, after the refrigerator door is opened and closed for a period of time, the temperature of the outside air entering the refrigerator drops, and the refrigerator is in a negative pressure state. The refrigerator absorbs the air in the first cavity 101 into the compressor chamber, and the air pressure in the first cavity 101 is reduced to form a negative pressure. Then the defrost water in the second cavity 201 enters the first cavity 101 to make up for the negative pressure in the first cavity 101. The air in the first cavity 101 is used to make up for the negative pressure in the refrigerator, and the bubble sound generated when the outside air enters the compressor chamber is reduced. At the same time, a negative pressure is formed in the second cavity 201, and then the outside air enters the second cavity 201 through the inlet of the second cavity 201 to balance the negative pressure in the second cavity 201.

[0043] After the door is opened and closed again, the negative pressure in the refrigerator decreases, and the water level in the first cavity 101 drops and enters the second cavity 201. When the liquid level in the second cavity 201 rises to the height of the outlet of the second cavity 201, the defrost water in the second cavity 201 is discharged along the outlet of the second cavity 201.

[0044] Optionally, the inlet of the first cavity 101 is opened on the top wall or the side wall of the first storage element 10 , and the outlet of the first cavity 101 is opened on the side wall or the bottom wall of the first storage element 10 .

[0045] In this embodiment, the inlet of the first cavity 101 is opened on the top wall of the first storage element 10, so that after the defrost water enters the first cavity 101 through the inlet of the first cavity 101, it falls vertically to the lower cavity part of the first cavity 101, thereby reducing the resistance of the defrost water when falling and improving the discharge speed of the defrost water in the first cavity 101.

[0046] By arranging the outlet of the first cavity 101 to be opened on the bottom wall of the first storage element 10, the defrost water in the first cavity 101 can be discharged faster, the discharge speed of the defrost water is increased, and the air content in the first cavity 101 is increased. In the case where the negative pressure in the refrigerator is relatively large, more air in the first cavity 101 can be used to replenish the refrigerator to balance the negative pressure of the refrigerator.

[0047] The outlet of the first cavity 101 is opened on the side wall of the first storage element 10, so as to limit the height of the water level in the first cavity 101 by using the outlet of the first cavity 101. When the water level in the first cavity 101 is higher than the outlet of the first cavity 101, the defrost water in the first cavity 101 flows out through the outlet of the first cavity 101 under the action of gravity, and enters the second cavity 201 through the inlet of the second cavity 201.

[0048] Specifically, when both the inlet and the outlet of the first cavity 101 are opened on the side wall of the first storage element 10 , the height of the inlet of the first cavity 101 needs to be higher than the height of the outlet of the first cavity 101 .

[0049] Optionally, the outlet of the second cavity 201 is opened on the side wall or the top wall of the second storage element 20 .

[0050] In this embodiment, the outlet of the second cavity 201 is opened on the top wall of the second storage element 20 to ensure that there is sufficient water in the second cavity 201 to form a water seal at the water outlet end of the drainage structure, thereby reducing the problem of outside air entering the press chamber through the drainage structure and causing the drainage outlet of the press chamber to be blocked by ice.

[0051] The outlet of the second cavity 201 is opened on the side wall of the second storage element 20, so as to limit the height of the water level in the second cavity 201 through the outlet of the second cavity 201. When the water level in the second cavity 201 is higher than the outlet of the second cavity 201, the defrost water in the second cavity 201 flows out through the outlet of the second cavity 201 under the action of gravity, thereby realizing the discharge of the defrost water.

[0052] Optionally, the inlet of the first cavity 101 is opened on the top wall or side wall of the first storage element 10 , and the outlet of the first cavity 101 is opened on the side wall or bottom wall of the first storage element 10 . The outlet of the second cavity 201 is opened on the side wall or top wall of the second storage element 20 .

[0053] Optionally, the storage element comprises: a storage tank body. The inner diameter of the storage tank body decreases along the height direction of the storage tank body. The storage element comprises a first storage element 10 and / or a second storage element 20.

[0054] In this embodiment, by setting the inner diameter of the storage tank body to decrease along the height direction of the storage tank body, the discharge speed of the defrost water in the storage tank body can be accelerated, that is, the discharge speed of the defrost water in the first cavity 101 and the second cavity 201 is increased, the drainage efficiency of the drainage structure is improved, and the practicality of the drainage structure is improved.

[0055] Specifically, the inner diameter of the storage tank body decreases from top to bottom along the height direction of the storage tank body, which can reduce the volume of the space below the storage tank body, thereby reducing the amount of defrost water in the storage tank body and accelerating the discharge speed of the defrost water in the storage tank body. The inner diameter of the storage tank body decreases from bottom to top along the height direction of the storage tank body, which can reduce the resistance encountered by the defrost water when it flows downward and accelerate the discharge speed of the defrost water in the storage tank body.

[0056] For example, in combination Figure 4 As shown, the storage tank body includes a release section 701, a vertical section 702 and a tightening section 703. The inner diameter of the release section 701 increases from top to bottom along the height direction of the storage tank body to reduce the resistance encountered by the defrost water when it flows downward. The inner diameter of the tightening section 703 decreases from top to bottom along the height direction of the storage tank body to reduce the volume of the lower space of the storage tank body to reduce the amount of defrost water in the storage tank body. The inner diameter of the vertical section 702 is equal in size along the height direction of the storage tank body and is equal to the maximum value of the inner diameter of the release section 701 and the maximum value of the inner diameter of the tightening section 703.

[0057] Optionally, combined Figure 1 , Figure 2 and Figure 3 As shown, the drainage structure further includes: a connecting hose 30 . One end of the connecting hose 30 is connected to the outlet of the first cavity 101 , and the other end of the connecting hose 30 is connected to the inlet of the second cavity 201 .

[0058] In this embodiment, a connecting hose 30 is provided, and one end of the connecting hose 30 is connected to the outlet of the first cavity 101, and the other end of the connecting hose 30 is connected to the inlet of the second cavity 201, so as to connect the first cavity 101 and the second cavity 201, so that the defrost water in the first cavity 101 can flow into the second cavity 201 through the drain hose, thereby realizing the defrost water discharge function of the drainage structure.

[0059] Optionally, combined Figure 1 , Figure 2 and Figure 3 As shown, the drainage structure further includes: an inlet pipe 40 and a mounting portion. The water inlet end of the inlet pipe 40 is used to communicate with the press chamber, and the water outlet end of the inlet pipe 40 is connected to the inlet of the first cavity 101. The mounting portion is arranged at the water inlet end of the inlet pipe 40. When the drainage structure is arranged in the refrigerator, the upper end surface of the mounting portion is in contact with the outer wall of the press chamber.

[0060] In this embodiment, a water inlet pipe 40 is provided, and the water inlet end of the water inlet pipe 40 is used to communicate with the press chamber, and the water outlet end of the water inlet pipe 40 is connected to the inlet of the first cavity 101, so that the press chamber drain port is connected to the first cavity 101, and the defrost water in the press chamber is discharged, and the defrost water discharge function of the drainage structure is realized. A mounting portion is provided at the water inlet end of the water inlet pipe 40, and the upper end surface of the mounting portion is fitted with the outer chamber wall of the press chamber, so that the water flowing out of the press chamber drain port directly flows into the water inlet pipe 40 along the water inlet end of the water inlet pipe 40, thereby reducing the problem of defrost water overflowing due to the gap between the drain port of the press chamber and the water inlet pipe 40.

[0061] Optionally, combined Figures 1 to 4 As shown, the inner diameter of the water inlet pipe 40 decreases from top to bottom in the height direction. In this way, the inclined pipe wall of the water inlet pipe 40 is used to collect the defrost water flowing out of the drainage port of the press chamber, increase the kinetic energy of the water entering the water inlet pipe 40, reduce the accumulation of defrost water in the water inlet pipe 40, and thus speed up the outflow speed of the water in the press chamber, thereby improving the practicality of the drainage structure.

[0062] Optionally, combined Figures 1 to 4 As shown, the mounting portion 80 includes: a mounting plane. A water outlet is provided on the mounting plane, and the water outlet corresponds to the drain outlet of the press chamber. In this way, the problem of defrosting water overflowing due to a gap between the drain outlet of the press chamber and the water inlet pipe 40 can be reduced.

[0063] Optionally, combined Figures 1 to 4 As shown, the inner diameter of the water inlet pipe decreases from top to bottom in the height direction. The mounting portion 80 comprises: a mounting plane. A water outlet is provided on the mounting plane, and the water outlet corresponds to the drainage outlet of the press chamber.

[0064] Optionally, combined Figure 1 , Figure 2 and Figure 3 As shown, the drainage structure further includes: a water outlet pipe 50. The water inlet end of the water outlet pipe 50 is connected to the outlet of the second cavity 201.

[0065] In this embodiment, a water outlet pipe 50 is provided to discharge the defrost water in the second cavity 201 , thereby realizing the defrost water discharge function of the drainage structure.

[0066] Specifically, when the refrigerator is in a negative pressure state, the air in the first cavity 101 enters the refrigerator through the water inlet pipe 40 to balance the negative pressure in the refrigerator, and the first cavity 101 is in a negative pressure state. The water in the second cavity 201 enters the first cavity 101 through the connecting hose 30 to balance the negative pressure in the first cavity 101, and the second cavity 201 is in a negative pressure state. The outside air enters the second cavity 201 through the water outlet pipe 50 to balance the negative pressure in the second cavity 201.

[0067] Optionally, combined Figure 1 , Figure 2 and Figure 3 As shown, the drainage structure further includes: a water receiving box 60. The water receiving box 60 is arranged corresponding to the outlet of the second cavity 201, and is used to receive the defrost water flowing out of the outlet of the second cavity 201.

[0068] In this embodiment, the water receiving box 60 is provided to receive the defrost water flowing out of the outlet of the second cavity 201, thereby realizing storage of the defrost water, reducing the problem of damage to the refrigerator caused by the outflow of defrost water, and improving the practicality of the drainage structure.

[0069] Specifically, when the drainage structure includes a water outlet pipe 50 , the water receiving box 60 is disposed corresponding to the water outlet of the water outlet pipe 50 .

[0070] Optionally, the drainage structure further includes: a heating element. The heating element is disposed in the water receiving box 60 and is used to heat the defrosting water in the water receiving box 60 .

[0071] In this embodiment, a heating element is provided to heat the defrost water in the water receiving box 60 so as to evaporate the defrost water, thereby reducing the amount of defrost water in the water receiving box 60 and reducing the problem of overflow of defrost water discharged from the second storage element 20 after the water receiving box 60 is full of defrost water, thereby improving the practicality of the drainage structure.

[0072] In some embodiments, a refrigerator is provided, comprising: a refrigerator body and a drainage structure for the refrigerator as described in any one of the above embodiments. The refrigerator body comprises a press chamber and a drainage port, and the drainage port is provided in the chamber wall of the press chamber. In the drainage structure for the refrigerator as described in any one of the above embodiments, the water inlet of the first cavity 101 is connected to the drainage port.

[0073] In this embodiment, the drainage structure for a refrigerator described in any one of the above embodiments is provided in the refrigerator to discharge the defrost water in the compressor chamber. In addition, by limiting the inlet of the second cavity 201 to be opened on the bottom wall of the second storage element 20, and the height of the outlet of the second cavity 201 is higher than the height of the inlet of the second cavity 201, it is ensured that water is always stored in the second cavity 201, and the water seal at the outlet end of the drainage structure is achieved, reducing the outside air from entering the compressor chamber through the drainage device, and reducing the problem of water molecules condensing at the drain port when encountering cold and causing the drain port to be blocked. In addition, when the refrigerator is under negative pressure, the air in the first cavity 101 is absorbed into the refrigerator to balance the negative pressure of the refrigerator and reduce the bubble sound generated when the outside air enters the compressor chamber.
