Abstract
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.

The ventilation structure is arranged in the water receiving part 201 and connects the external space of the water receiving box 20 and the internal space of the water receiving part. The ventilation port of the ventilation structure located in the water receiving part is higher than the height of the water outlet of the water receiving part, so that the internal space of the pipe body assembly 10 is connected with the external space. The water molecule filtering structure 30 is arranged in the ventilation structure, and the water molecule filtering structure 30 is used to filter water molecules in the air.
[0046] The drainage structure 100 for a refrigerator provided by the embodiment of the present disclosure is provided with a water receiving portion 201 on the water receiving box 20, so that the water receiving portion 201 receives the water flowing out of the pipe body assembly 10. At the same time, through the ventilation structure, the space in the press chamber 2001 can be directly connected with the external space, so that the outside air can enter the press chamber 2001 without passing through the water flowing out of the pipe body assembly 10, thereby reducing the bubble sound generated when the outside air enters the press chamber 2001. By setting the height of the ventilation port located inside the water receiving portion 201 of the ventilation structure to be higher than the height of the water outlet of the water receiving portion 201, so that the water level in the water receiving portion 201 is lower than the height of the ventilation port, the defrost water entering the ventilation structure is reduced to cause the defrost water to overflow. In addition, by providing a water molecule filtering structure 30, water molecules in the outside air are blocked, thereby reducing the problem of water molecules condensing at the drain outlet 2002 when encountering cold and causing the drain outlet 2002 to be blocked.
[0047] Specifically, the height of the water outlet of the water receiving portion 201 is higher than the height of the water outlet end 102 of the pipe body assembly 10, so as to form a water seal at the water outlet end 102 of the pipe body assembly 10, reduce the external air from entering the pipe body assembly 10 through the water in the water receiving portion 201, and reduce the bubble sound generated when the external air enters the press chamber 2001. Figure 2 , Figure 3 and Figure 6As shown, the water receiving box 20 also includes a water storage space 203. The water receiving portion 201 includes: a protruding tube 2011. The inner tube wall of the protruding tube 2011 and the outer wall of the ventilation structure are configured as a water receiving groove 2013, and the pipe body assembly 10 is inserted into the water receiving groove 2013, and the end of the pipe body assembly 10 is spaced from the bottom wall of the water receiving groove 2013. The water outlet of the water receiving portion 201 is connected to the water receiving groove 2013.
[0048] In this embodiment, a protruding tube 2011 is provided to form a water receiving groove 2013 through the inner tube wall of the protruding tube 2011 and the outer wall of the ventilation structure, so as to receive the defrost water flowing out of the water outlet end 102 of the tube body assembly 10 and discharge the defrost water in the compressor chamber 2001.
[0049] Optionally, the ventilation structure includes: a ventilation pipe 2012. The ventilation pipe 2012 is arranged in the protruding pipe 2011. One end of the ventilation pipe 2012 is penetrated through the side wall of the water storage space 203 to form a ventilation hole 202. The outer wall of the ventilation pipe 2012, the side wall of the water storage space 203 and the inner wall of the protruding pipe 2011 are configured as a water receiving groove 2013. The pipe body assembly 10 is located between the outer wall of the ventilation pipe 2012 and the inner wall of the protruding pipe 2011, and part of the ventilation pipe 2012 is located in the pipe body assembly 10. There is a distance between the inner pipe wall of the pipe body assembly 10 and the outer wall of the ventilation pipe 2012, and there is a distance between the outer pipe wall of the pipe body assembly 10 and the inner wall of the protruding pipe 2011.
[0050] In this embodiment, a water receiving groove 2013 is formed by the outer wall of the vent pipe 2012, the side wall of the water storage space 203 and the inner wall of the protruding tube 2011 to receive the defrost water flowing out of the water outlet end 102 of the pipe body assembly 10, so as to discharge the defrost water in the press chamber 2001. At the same time, one end of the vent pipe 2012 is penetrated through the side wall of the water storage space 203 to form a vent hole 202, and part of the vent pipe 2012 is located in the pipe body assembly 10 to reduce the defrost water flowing out of the water outlet end 102 of the pipe body assembly 10 flowing out of the water receiving box 20 through the vent hole 202, and the water inlet end 101 of the pipe body assembly 10 is connected with the external space through the vent hole 202, so that the press chamber 2001 is connected with the external space through the vent pipe 2012. The outside air can enter the press chamber 2001 without passing through the water flowing out of the tube body assembly 10, thereby reducing the bubble sound generated when the outside air enters the press chamber 2001.
[0051] Specifically, combined Figure 3 As shown, the outer wall of the water molecule filtering structure 30 abuts against the inner wall of the ventilation tube 2012 , that is, the outer wall of the water molecule filtering structure 30 abuts against the hole wall of the ventilation hole 202 .
[0052] Optionally, combined Figure 3 and Figure 6As shown, the height of the ventilation pipe 2012 is higher than the height of the water outlet of the water receiving portion 201 .
[0053] In this embodiment, by limiting the height of the protruding tube 2011 to be greater than the height of the vent tube 2012, the height of the water surface in the water receiving portion 201 is reduced to be higher than the vent tube 2012, thereby reducing the problem of defrost water flowing out of the water receiving box 20 through the vent hole 202 and causing the defrost water of the refrigerator 200 to flow out, thereby improving the practicality of the drainage structure 100.
[0054] Optionally, combined Figure 3 and Figure 6 As shown, the raised pipe 2011 further includes an overflow groove 2014. The overflow groove 2014 is connected to the water receiving groove 2013, and the groove wall of the overflow groove 2014 is lower than the groove wall of the water receiving groove 2013. The upper end of the overflow groove 2014 is configured as a water outlet of the water receiving portion 201.
[0055] In this embodiment, an overflow groove 2014 is provided, and the upper end of the overflow groove 2014 is used as the water outlet of the water receiving part 201, so that the height of the overflow groove 2014 is used to limit the water level in the water receiving part 201, thereby reducing the water level of the defrost water being higher than the height of the ventilation port of the ventilation structure, thereby reducing the problem of defrost water flowing out of the water receiving box 20 from the ventilation structure and causing the defrost water of the refrigerator 200 to flow out, thereby improving the practicality of the drainage structure 100.
[0056] Specifically, the height of the overflow trough 2014 is less than the height of the water receiving trough 2013 .
[0057] Optionally, the water molecule filtering structure includes a molecular sieve.
[0058] Optionally, the molecular sieve 30 includes: a shell and a water absorbent. The shell is provided with a through hole for circulating air. The water absorbent is arranged in the through hole, and the water absorbent can absorb water molecules in the air flowing through the water absorbent. In this way, due to the hydrophilicity of the water absorbent, water vapor will be adsorbed on the water absorbent when passing through, and air can flow through the through hole of the molecular sieve 30 and then enter the press chamber 2001. The water molecules in the air inside and outside the drain pipe 1031 are reduced, and the problem of water molecules condensing at the drain outlet 2002 when encountering cold and causing the drain outlet 2002 to be blocked is reduced.
[0059] Specifically, the outer wall of the shell of the molecular sieve 30 abuts against the hole wall of the vent hole 202 .
[0060] Optionally, combined Figure 6As shown, the water receiving box 20 further includes a box body 204. The box body 204 is provided with a water storage space 203, which is arranged outside the water receiving portion 201. The ventilation structure is connected to the bottom wall of the box body 204, and the ventilation structure communicates the upper space of the box body 204 with the lower space of the box body 204.
[0061] In this embodiment, the box body 204 is provided so that the water storage space 203 of the box body 204 can be used to store the defrost water flowing out of the water receiving portion 201 , thereby reducing the outflow of the defrost water and improving the practicality of the drainage structure 100 .
[0062] Optionally, the water receiving box 20 further includes a heating element. The heating element is wound around the outer wall of the box body 204, or the heating element is arranged in the water storage space 203. The heating element is used to heat the defrost water in the water storage space 203 to evaporate the defrost water.
[0063] Optionally, combined Figure 3 and Figure 4 As shown, the pipe body assembly 10 includes: a pipe body 103 and a water guide plate 104. The water inlet of the pipe body 103 is connected to the water outlet of the press chamber 2001, and the water outlet of the pipe body 103 is inserted in the water receiving part 201. The water guide plate 104 is arranged on the inner tube wall of the pipe body 103 and is located at one end of the water outlet of the pipe body 103. When the pipe body 103 is inserted in the water receiving part 201, the water guide plate 104 can block the ventilation port of the ventilation structure. A water flow port 105 is formed between the side wall of the water guide plate 104 and the inner tube wall of the pipe body 103. When the water receiving box 20 includes a protruding tube 2011, the water flow port 105 is arranged corresponding to the water receiving groove 2013.
[0064] In this embodiment, a water guide plate 104 is provided in the tube body 103 to achieve the drainage effect on the defrost water in the tube body assembly 10, and the defrost water is guided to pass through the water flow port 105 and then fall into the water receiving portion 201 along the inner wall of the tube body 103. The water guide plate 104 is used to block the ventilation port (i.e., the vent hole 202) of the ventilation structure, thereby blocking the vent hole 202, reducing the defrost water entering the ventilation pipe 2012, reducing the problem of defrost water flowing out of the water receiving box 20 from the vent hole 202 and causing the defrost water of the refrigerator 200 to flow out, and improving the practicality of the drainage structure 100.
[0065] Optionally, combined Figure 3 , Figure 4 and Figure 5 As shown, the water guide plate 104 is obliquely arranged on the inner wall of the tube body 103 .
[0066] In this embodiment, the water guide plate 104 is inclined to increase the drainage effect of the water guide plate 104, so that after the defrost water falls from a high place, the defrost water located on one side of the water guide plate 104 flows along the inclined water guide plate 104 to the side of the water outlet 105, and then falls into the water receiving groove 2013 along the tube wall of the tube body 103 on the side where the water outlet 105 is located. In addition, the inclined water guide plate 104 can reduce the accumulation of defrost water on the upper surface of the water guide plate 104 and accelerate the drainage speed. It also reduces the backflow of defrost water on the lower surface of the water guide plate 104, that is, reduces the flow of defrost water along the lower surface of the water guide plate 104 and falls into the ventilation structure, further reduces the problem of defrost water flowing out of the water receiving box 20 from the ventilation hole 202, and causes the defrost water of the refrigerator 200 to flow out, and improves the practicality of the drainage structure 100.
[0067] Optionally, the water guide plate 104 is disposed at a maximum distance between the water receiving groove 2013 and the water outlet of the water receiving portion 201 .
[0068] In this embodiment, the water guide plate 104 is arranged to be inclined to the maximum distance between the water receiving groove 2013 and the water outlet of the water receiving part 201, that is, the water outlet 105 is located above the maximum distance between the water receiving groove 2013 and the water outlet of the water receiving part 201. In this way, after the defrost water falls into the water receiving groove 2013, it can flow along the water receiving groove 2013 to the minimum distance between the water receiving groove 2013 and the water outlet of the water receiving part 201, and then enter the overflow groove 2014. This can reduce the problem that the defrost water that continuously falls due to the minimum distance between the water receiving groove 2013 and the water outlet of the water receiving part 201 caused by the water outlet 105 corresponding to the minimum distance between the water receiving groove 2013 and the water outlet of the water receiving part 201 affects the discharge of the defrost water at the maximum distance between the water receiving groove 2013 and the water outlet of the water receiving part 201.
[0069] Optionally, combined Figure 3 and Figure 4 As shown, the pipe body 103 includes: a drain pipe 1031, a connecting hose 1032 and a drain sleeve 1033. The drain pipe 1031 is used to connect the water outlet of the press chamber 2001. One end of the connecting hose 1032 is connected to the water outlet of the drain pipe 1031. The water inlet of the drain sleeve 1033 is connected to the other end of the connecting hose 1032. The water guide plate 104 is arranged on the inner pipe wall of the drain sleeve 1033.
[0070] In this embodiment, the defrost water in the press chamber 2001 is discharged from the press chamber 2001 by setting the drain pipe 1031. The drain sleeve 1033 with the water guide plate 104 is set to use the water guide plate 104 to block the air inlet of the vent pipe 2012, thereby blocking the vent hole 202, reducing the defrost water entering the vent pipe 2012, reducing the defrost water flowing out of the water receiving box 20 from the vent hole 202, and reducing the defrost water outflow of the refrigerator 200, thereby improving the practicality of the drainage structure 100. At the same time, by setting the connecting hose 1032, the drain pipe 1031 is connected to the connecting sleeve through the connecting hose 1032, so as to adapt to the drain pipe 1031 and the connecting sleeve set at different positions, and realize the defrost water from the press chamber 2001 to the water receiving box 20, thereby improving the practicality of the drainage structure 100.
[0071] Optionally, combined Figure 4 , Figure 5 and Figure 6 As shown, a protrusion 2015 is provided on the groove wall of the water receiving groove 2013. The drainage sleeve 1033 includes: a pipe body 1034 and a convex strip 1035. The pipe body 1034 is inserted into the water receiving groove 2013. The water guide plate 104 is provided on the inner wall of the pipe body 1034. The convex strip 1035 is provided on the outer peripheral wall of the pipe body 1034. The protrusion 2015 is engaged with the convex strip 1035.
[0072] In this embodiment, the protrusion 2015 and the convex strip 1035 are provided to realize the installation, fixation and limitation of the drainage sleeve 1033, that is, there is a distance between the outer tube wall of the drainage sleeve 1033 and the groove wall of the water receiving groove 2013, so that the water in the water receiving groove 2013 can flow and then flow into the water storage space 203 through the water outlet of the water receiving part 201.
[0073] Specifically, the drainage sleeve 1033 is a hard structure, and the inner diameter of the drainage sleeve 1033 is set larger than the outer diameter of the ventilation pipe 2012, so as to limit the distance between the inner tube wall of the pipe body assembly 10 and the outer side wall of the ventilation pipe 2012.
[0074] Combination Figure 8 As shown, the embodiment of the present disclosure provides a refrigerator 200, comprising: a refrigerator body 2003 and a drainage structure 100 for a refrigerator as described in any one of the above embodiments. The refrigerator body 2003 comprises a press chamber 2001, and a chamber wall of the press chamber 2001 is provided with a drainage port 2002. The water inlet end 101 of the drainage structure 100 is connected to the drainage port 2002 of the press chamber 2001.
[0075] The refrigerator 200 provided in the embodiment of the present disclosure realizes that the water flowing out of the pipe body assembly 10 is received by the water receiving portion 201 of the water receiving box 20 through the drainage structure 100 disposed on the refrigerator body 2003. At the same time, the space in the press chamber 2001 is directly connected to the external space through the vent hole 202 of the drainage structure 100, so that the outside air can enter the press chamber 2001 without passing through the water flowing out of the pipe body assembly 10, thereby reducing the bubble sound generated when the outside air enters the press chamber 2001. In addition, by providing a water molecule filtering structure 30, water molecules in the outside air are blocked, thereby reducing the problem of water molecules condensing at the drain outlet 2002 when encountering cold and causing the drain outlet 2002 to be blocked.
