Technical Field
[0001] The present application relates to the field of household appliances, and in particular to a drain pipe and a refrigerator. Background Art
[0002] In the current design of refrigerators, the function of the refrigerator drain pipe is to drain the water produced after the refrigerator defrosts. Therefore, one end of the drain pipe is connected to the refrigerator body, and the other end is connected to the outside of the refrigerator. When the refrigerator is running, when there is no liquid discharged, the air in the environment will enter the refrigerator through the drain pipe, causing the heat load and humidity of the refrigerator to increase, affecting the performance of the refrigerator. Utility Model Content
[0003] The present application provides a liquid discharge pipe and a refrigerator, which can prevent external gas from returning to the liquid discharge pipe and have a better sealing effect.
[0004] Specifically, the present application is implemented through the following technical solutions:

[0008] A float located inside the drainage pipe body, the float being movably disposed at the first opening, the float including a first position and a second position, when the float is located at the first position, the float blocks the first opening, and when the float moves to the second position, the float is suspended above the first opening, connecting the drainage pipe body with the outside of the drainage pipe body through the inner tube;
[0009] The float moves from the first position to the second position under the action of the liquid inside the discharge pipe body.

[0016] Optionally, the shape of the contact position between the first opening and the float is a hollow bowl shape having the same radius as the float.
[0017] Optionally, the diameter of the float is greater than 80% of the inner diameter of the drainage pipe body.
[0018] Another aspect of the present application provides a refrigerator, comprising the drain pipe described in any one of the above items, wherein the drain pipe is used to discharge defrost water in the refrigerator.
[0019] The present application provides a drain pipe and a refrigerator. The drain pipe of the present application is provided with an inner tube and a float. When the drain pipe does not need to drain, the float will be located at the first position and block the first opening under the action of its own gravity, which can prevent the gas outside the drain pipe body from entering the inside of the drain pipe body. Prevent gas from entering the equipment connected to the drain pipe through the drain pipe, thereby affecting the performance of the equipment. When the drain pipe needs to drain, when the liquid submerges the float, the buoyancy generated by the liquid on the float is greater than the self-gravity of the float, and the float will be suspended above the first opening under the action of the buoyancy, and the liquid can be discharged through the inner tube through the first opening on the liquid outlet side. It not only achieves sealing the drain pipe when there is no liquid discharge, preventing external gas from returning to the drain pipe, but also ensures the smooth discharge. The inner tube further extending to the liquid inlet side can reduce the influence of the outside of the drain pipe on the float, for example, the airflow outside the drain pipe blows up the float to affect the sealing effect, so that the sealing effect of the float is better.

[0024] Please refer to Figure 1 The present application proposes a drain pipe, comprising a drain pipe body 100, an inner tube 200, and a float 300. The drain pipe body 100 comprises a liquid inlet side 110 and a liquid outlet side 120. The inner tube 200 is sleeved inside the drain pipe body 100, the inner tube 200 is located at the liquid outlet side 120, and extends toward the liquid inlet side 110. The drain pipe body 100 is connected with the outside of the drain pipe body 100 through the inner tube 200. That is, the liquid flowing in from the liquid inlet side 110 is discharged from the drain pipe body 100 through the inner tube 200 located at the liquid outlet side 120. The inner tube 200 comprises a first opening 210 close to the liquid inlet side 110, and the liquid flows into the inner tube 200 from the first opening 210. The float 300 is located inside the drain pipe body 100, and the float 300 is movably arranged at the first opening 210.
[0025] Please combine Figure 2 The float 300 includes a first position and a second position. When the float 300 is in the first position, the float 300 blocks the first opening 210, and can isolate the outside of the drain pipe body 100 from the inside of the drain pipe body. When the float 300 moves to the second position, the float 300 is suspended above the first opening 210, and the drain pipe body 100 is connected to the outside of the drain pipe body 100 through the inner tube 200. Under the action of the liquid inside the drain pipe body 100, the float 300 moves from the first position to the second position.
[0026] When the drain pipe does not need to drain, that is, there is no liquid inside the drain pipe body 100, the float 300, under the action of its own gravity, will be located at the first position to block the first opening 210, which can prevent the gas outside the drain pipe body 100 from entering the drain pipe body 100. Prevent gas from entering the equipment connected to the drain pipe through the drain pipe, thereby affecting the performance of the equipment. When the drain pipe needs to drain, liquid will enter from the liquid inlet side 110 and flow to the liquid outlet side 120. When the liquid submerges the float 300, the buoyancy generated by the liquid on the float 300 is greater than the own gravity of the float 300, and the float 300 will be suspended above the first opening 210 under the action of the buoyancy, and the liquid can be discharged from the inner tube 200 through the first opening 210 on the liquid outlet side 120. This embodiment not only achieves sealing the drain pipe when there is no liquid discharge, preventing external gas from returning to the drain pipe, but also ensures the smooth discharge of liquid.
[0027] Furthermore, the inner tube 200 for draining liquid is located at the liquid outlet side 120 and extends toward the liquid inlet side 110. A first cavity 220 is formed between the outer wall of the inner tube 200 and the inner wall of the liquid inlet tube body 100. The liquid first enters the first cavity 220 and the liquid level rises along the outer wall of the inner tube 200 until it partially covers the float 300, so that the float 300 floats up and then flows into the inner tube 200 from the first opening 210. After the liquid is discharged, the float 300 falls back to the first position. The float 300 is located at the first opening 210 facing the liquid inlet side 110, which can reduce the influence of the outside of the drain pipe on the float 300, for example, the airflow outside the drain pipe blows up the float 300 to affect the blocking effect. Furthermore, this embodiment can make the sealing effect of the float 300 better.
[0028] In one embodiment, the float 300 is located at the first position, and the contact position between the float 300 and the first opening 210 is a line contact seal, so that the shape of the float 300 can be elliptical, quadrilateral, cylindrical, etc., or the shape of the first opening 210 can be matched with the float 300 to achieve line contact. In this embodiment, the shape matching between the float 300 and the first opening 210 of the inner tube is relatively simple, and there are many shapes that meet the line contact, and the shape of the float 300 can be selected in many ways.
[0029] In another embodiment, when the float 300 is at the first position, the float 300 and the first opening 210 are in surface contact sealing, that is, the shapes of the contact surfaces of the float 300 and the first opening 210 of the inner tube 200 are consistent, and the surface contact sealing has a larger sealing area, so the sealing effect is better.
[0030] In one embodiment, the density of the float 300 is configured to be 0.2-0.5 of the density of the liquid in the discharge tube body. For example, when the discharged liquid is water, the density of the float 300 can be 0.2, 0.3, 0.4, 0.5, etc. of the density of water. The density of the float 300 is less than the density of the liquid, ensuring that the float 300 can float after the liquid partially submerges the float. And by selecting the density, the volume of the liquid that submerges the float 300 when the float 300 floats can be controlled. The float 300 can be solid or hollow.
[0031] In another embodiment, the float 300 is a solid float, which can ensure that the buoyancy force on each part of the float 300 is uniform, and ensure the stability of the float 300 in the second position. When falling back to the first position, the float 300 is in sealed contact. In addition, at the same density, the solid float has a small volume and is easy to prepare. The solid float can be made of wood or plastic, for example.
[0032] In one embodiment, the inner diameter of the inner tube 200 is 40%-60% of the inner diameter of the discharge pipe body 100, for example, it can be 40%, 42%, 45%, 50%, 55%, 60%, etc. First, this ratio can facilitate the production of the liquid inlet pipe. Secondly, it can facilitate the floating body 300 to fall back from the second position to the first position, because if the inner diameter of the inner tube 200 is designed to be too small, the floating body 300 cannot be stable in the first position. The liquid inlet pipe including the inner tube 200 of the present application can be made by stamping.
[0033] In one embodiment, the float 300 is a spherical float, and the radius of the spherical float is the same everywhere. During the process of the float 300 falling back from the second position to the first position, the spherical float can automatically align its center of gravity at the first opening 210 due to its shape and accurately fall back to the first position.
[0034] In one embodiment, the shape of the first opening 210 and the floating body 300 contact position is a hollow bowl shape with the same radius as the floating body 300, and the first opening 210 and the floating body 300 are in surface contact and sealing. The floating body 300 is spherical, and the first opening 210 is in a hollow bowl shape. The radius of the two surfaces in contact with each other is consistent, so the floating body 300 and the first opening 210 can be in surface contact at the contact position, and the sealing effect is better. In addition, the first opening 210 is in a hollow bowl shape, which can guide the spherical floating body 300 to fall back to the first position more accurately.
[0035] In one embodiment, the diameter of the float 300 is greater than 80% of the inner diameter of the drain pipe body 100, and can be 80%, 85%, 90%, etc. of the inner diameter of the drain pipe body 100. The float 300 is a spherical float. During the process of the float 300 falling back from the second position to the first position, the float 300 can be limited by the collision of the inner wall of the drain pipe body 100, ensuring that the spherical float is roughly in the middle position of the drain pipe body 100, and the inner tube 200 is also in the center. Therefore, this embodiment can further ensure that the float 300 accurately falls back to the first position.
[0036] The present application also provides a refrigerator, comprising the drain pipe described in any of the above embodiments, wherein the drain pipe is used to discharge defrost water in the refrigerator. The refrigerator provided by the present application can prevent external gas from entering the interior of the refrigerator through the drain pipe when the drain pipe does not drain water, thereby affecting the performance of the refrigerator.
[0037] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
