Description

Technical Field

[0001] This invention relates to the field of refrigeration technology, and in particular to a drain pipe assembly for refrigeration equipment and refrigeration equipment. Background Technology

[0002] Currently, most freezers sold on the market are equipped with drain pipes to allow water inside the freezer to drain to the outside. Existing technology places the drain pipes inside the freezer, and the outlet of the drain pipe is normally sealed with a drain plug to prevent cold air inside the freezer from escaping through the drain pipe. The drain plug is only opened to allow water to flow out during defrosting.

[0003] In existing technology, the drain plug of a freezer is generally designed to be detachably connected to the drain pipe. Drainage is achieved when the drain plug is removed from the drain pipe, and it seals the drain pipe when it is installed and fixed in place. However, because the drain plug and drain pipe are separate components, this design makes it easy for the drain plug to be lost. Summary of the Invention

[0004] The purpose of this invention is to provide a drain pipe assembly for refrigeration equipment to overcome the shortcomings of the prior art. It can open the drain pipe to drain water even when the drain plug and drain pipe are not completely disassembled, thus avoiding the loss of the drain plug.

[0005] The present invention provides a drain pipe assembly for a refrigeration device, comprising: a drain pipe and a drain plug that cooperates with the drain pipe, the drain plug having a drain channel communicating with the outlet of the drain pipe, and the outlet of the drain channel being disposed on the side wall of the drain plug; the drain plug is movably disposed within the drain pipe and has a draining state and a non-draining state.

[0006] In the non-draining state, the drain plug is positioned inside the drain pipe, and the outlet is opposite to the inner wall of the drain pipe.

[0007] In the draining state, part of the drain plug moves outside the drain pipe to expose the outlet.

[0008] Furthermore, the drain plug is provided with a sliding groove extending in the axial direction, and the inner wall of the drain pipe is provided with a guide post that slides in cooperation with the sliding groove; when switching between the draining state and the non-draining state, the drain plug slides in the axial direction of the drain pipe.

[0009] Furthermore, the drain plug also has a limiting portion that cooperates with the guide post to limit the sliding stroke of the drain plug in the axial direction.

[0010] Furthermore, the limiting part is disposed in the slide groove and located on the first side wall of the slide groove, and the plane of the first side wall is oriented toward the axial direction of the drain plug.

[0011] Furthermore, the side wall of the drain plug also has a disassembly guide groove that slides with the guide post. The disassembly guide groove has an inlet that communicates with the slide groove and an outlet that is disposed at the first end of the drain plug. The guide post slides out of the disassembly guide groove from the outlet to separate the drain plug from the drain pipe.

[0012] Furthermore, the inlet of the disassembly guide groove is located on the second side wall of the slide, and the plane of the second side wall of the slide faces the circumference of the drain plug.

[0013] Furthermore, during the sliding of the guide column along the chute, the outlet opening faces downward, the opening direction of the chute is perpendicular to the opening direction of the outlet, and the chute forms an upper second sidewall and a lower second sidewall arranged opposite to each other, with the inlet of the disassembly guide groove located on the upper second sidewall.

[0014] Furthermore, the disassembly guide groove has a straight segment extending along the axial direction of the drain plug and a spiral segment connecting the straight segment and the slide groove, the straight segment and the slide groove being disposed on opposite sides of the drain plug.

[0015] Furthermore, the straight segment also has a guide section near the outlet, and the size of the guide section slot gradually increases as it approaches the outlet.

[0016] Furthermore, when switching between the draining state and the non-draining state, the drain plug and the drain pipe slide relative to each other in a spiral direction.

[0017] A refrigeration device includes a housing, a water receiving tray disposed within the housing, and a drain pipe assembly disposed on the water receiving tray. The drain pipe has a bent portion that is fixedly connected to the water receiving tray and a connecting pipe communicating with the bent portion. A drain plug is disposed at the outlet of the connecting pipe.

[0018] Furthermore, the connecting pipe is inclined and its height gradually decreases in the direction away from the bend.

[0019] Furthermore, the bend section is detachably connected and fixed to the water receiving tray. The bend section has a bend body and an annular baffle provided on the bend body. The water receiving tray is provided with an installation hole adapted to the bend body. The size of the installation hole is smaller than the size of the annular baffle. The annular baffle is pressed tightly against the water receiving tray. The drain pipe assembly also has fasteners that can be detachably installed and fixed on the bend body. After the bend body is installed and fixed, the fasteners are attached to the lower surface of the water receiving tray.

[0020] Furthermore, the fastener is a retaining ring, and the bent tube body is provided with an annular retaining groove that matches the retaining ring.

[0021] Furthermore, the water receiving tray is provided with an annular clearance groove that is adapted to the annular baffle, so that after the drain pipe is installed and fixed, the upper surface of the annular baffle does not protrude beyond the upper surface of the water receiving tray.

[0022] Compared with the prior art, the solution disclosed in this embodiment of the present invention sets the outlet of the drainage channel on the side wall of the drain plug. During drainage, moving part of the drain plug outward to remove it from the drain pipe exposes the outlet, facilitating the flow of water out of the drain pipe. During this process, the drain plug remains attached to the drain pipe, achieving drainage without disassembling it, thus effectively preventing loss after disassembly. In the non-drainage state, pushing the removed drain plug inward allows the exposed outlet to be contained within the drain pipe. With the outlet aligned with the inner wall of the drain pipe and its edge pressed against the inner side wall, the outlet is sealed off, thus sealing the entire drain pipe. This method is simple and convenient to use. Attached Figure Description

Detailed Implementation

[0034] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] Embodiments of the present invention: such as Figure 1-6 As shown, a drain pipe assembly for refrigeration equipment is disclosed. This drain pipe assembly is used in freezers, refrigerators, or other refrigeration equipment to drain defrosted water from the refrigerator body after defrosting.

[0036] Specifically, the drain pipe assembly includes: a drain pipe 1 and a drain plug 2 that cooperates with the drain pipe 1. The drain plug 2 is used to seal the drain pipe 1. When the drain pipe 1 is not in use, it needs to be sealed to prevent outside air from entering the cabinet and affecting the cooling effect. In this embodiment, the drain plug 2 is directly inserted into the drain pipe 1. The two can be connected by an interference fit or by superimposing other connection and fixing methods on the basis of the interference fit, or even by other connection and fixing methods.

[0037] The drain pipe 1 is generally a cylindrical pipe, so the drain plug 2 has a cylindrical structure that is adapted to the inner wall of the drain pipe 1. The drain plug 2 has a drain channel 20 that communicates with the outlet of the drain pipe 1. The inlet of the drain channel 20 is located at the bottom of the cylindrical drain plug. Part of the drain channel 20 extends along the axial direction of the drain plug to facilitate communication with the drain pipe 1. At the same time, the outlet 201 of the drain channel 20 is located on the side wall of the drain plug 2.

[0038] The drain plug 2 is movably disposed within the drain pipe 1 and has a draining state and a non-draining state:

[0039] In the non-drainage state, the drain plug 2 is positioned inside the drain pipe 1, and the outlet 201 is opposite to the inner wall of the drain pipe 1; the outlet 201 is contained inside the drain pipe 1, and the side wall of the drain plug 2 along the edge of the outlet 201 is in contact with the inner wall of the drain pipe 1, thereby isolating the drainage channel 20 from the outside world and giving the drain plug 2 a sealing function.

[0040] In the drainage state, a portion of the drain plug 2 moves outside the drain pipe 1, exposing the outlet 201. During drainage, the drain plug 2 moves towards the outlet of the drain pipe 1, causing a portion of the drain plug 2 to exit the drain pipe 1. The outlet 201 of the drainage channel 20 is located precisely on this removed portion of the drain plug 2, exposing the outlet 201 and connecting the drainage channel 20 to the outside, thus allowing water to flow outwards from the drain pipe 1, effectively opening the drain pipe 1. It should be noted that during the drainage state, a portion of the drain plug 2 remains inside the drain pipe 1 and adheres to the inner wall of the drain pipe 1, forming a blockage. In this case, the only connection between the drain pipe 1 and the outside is the drainage channel 20, and water can only be discharged to the outside through the drainage channel 20.

[0041] like Figure 3As shown, in this embodiment, the outlet 201 of the drainage channel 20 is located on the side wall of the drain plug 2. During drainage, partially moving the drain plug 2 outwards to remove it from the drain pipe 1 exposes the outlet 201 of the drainage channel 20, facilitating the outflow of water from the drain pipe. During this process, the drain plug 2 remains attached to the drain pipe 1, maintaining a fixed assembly. This allows for the discharge of water from the drain pipe 1 without disassembling the drain plug 2, effectively preventing its loss after disassembly. In the non-drainage state, pushing the removed drain plug 2 inwards allows the exposed outlet 201 to be contained within the drain pipe 1. With the outlet 201 facing the inner wall of the drain pipe 1 and its edge adhering to the inner side wall of the drain pipe 1, the outlet 201 is sealed off, thus sealing off the drain pipe 1. This method is simple and convenient to use.

[0042] During the transition from non-drainage to drainage mode, the drain plug 2 needs to be moved outward. The drain plug 2 can be moved directly outward along the axial direction of the drain pipe 1 under pulling force, or it can be moved in a straight line and pulled out directly. Of course, the drain plug 2 can also be screwed outward in a spiral direction. As a preferred embodiment, this description will focus on the example of the drain plug 2 being pulled outward along the axial direction of the drain pipe 1.

[0043] Specifically, the drain plug 2 is provided with a sliding groove 21 extending along the axial direction of the drain plug 2, which is consistent with the axial direction of the drain pipe 1. A guide post 11 is provided on the inner wall of the drain pipe 1, which slides in cooperation with the sliding groove 21. When switching between draining and non-draining states, the drain plug 2 slides along the axial direction of the drain pipe 1. During movement, the drain plug 2 moves along the extension direction of the sliding groove 21 under the guidance of the guide post 11 and the sliding groove 21. The cooperation of the guide post 11 and the sliding groove 21 ensures the stability of the drain plug 2 during movement.

[0044] Furthermore, the drain plug 2 also has a limiting part 22 that cooperates with the guide post 11 to limit the sliding stroke of the drain plug in the axial direction. The limiting part 22 can prevent the drain plug 2 from moving excessively in the axial direction. At the same time, if the water flow in the drain pipe 1 is large during drainage, it may push the drain plug 2 and cause it to disengage from the drain pipe. The cooperation between the limiting part 22 and the guide post 11 can also prevent the above problem from occurring. When the drain plug 2 slides in the axial direction until the limiting part 22 abuts against the guide post 11, if the drain plug 2 is pulled outward, the guide post 11 will act as a limit, preventing the drain plug 2 from moving further outward.

[0045] Specifically, in this embodiment, the limiting part 22 is placed inside the slide groove 21 and located on the first side wall 211 inside the slide groove 21. The plane of the first side wall 211 faces the axial direction of the drain plug 2, and the slide groove 21 extends outward from the first side wall 211. The normal of the plane of the first side wall 211 is parallel to the axial direction of the drain plug 2.

[0046] like Figure 6 As shown, if the axial direction of the drain plug 2 is taken as the left-right direction, the drain plug 2 has a first sidewall 211 and a third sidewall arranged and opposite to each other in the left-right direction. The first sidewall 211 and the second sidewall extend along the width direction of the slide groove 21, and the first sidewall 211 is located to the left of the third sidewall. During the switching process from the non-drainage state to the drainage state, the drain plug 2 slides outward along the axial direction of the drain pipe 1. During the initial sliding process, the guide post 11 slides and engages with the slide groove 21 to guide the movement of the drain plug 2. When the drain plug 2 moves to the point where the guide post 11 abuts against the first sidewall 211, the guide post 11 limits the movement of the drain plug 2, preventing the drain plug 2 from sliding off the drain pipe 1.

[0047] The cooperation between the guide post 11 and the drain plug 2 can limit the movement of the drain plug 2 in the axial direction, effectively preventing the drain plug 2 from falling off the drain pipe 1 during normal drainage. However, in actual use, the drain plug 2 needs to be disassembled to completely detach it from the drain pipe 1.

[0048] To facilitate the removal of the drain plug 2 from the drain pipe 1, the side wall of the drain plug 2 is provided with a disassembly guide groove 23 that slides with the guide post 11. The disassembly guide groove 23 has an inlet 231 that communicates with the slide groove 21 and an outlet 232 provided on the drain plug 2. The outlet 232 and the inlet 231 are arranged along the extension direction of the disassembly guide groove 23 and are located on opposite sides of the disassembly guide groove 23, and the outlet 232 is provided at the first end of the drain plug 2, which is the left end of the drain plug 2. When the drain plug 2 is installed and positioned in the drain pipe 1, the first end of the drain plug 2 extends into the drain pipe 1, and the guide post 11 slides out of the disassembly guide groove 23 from the outlet 232 to achieve the separation of the drain plug 2 from the drain pipe 1.

[0049] The removal guide groove 23 can guide the guide post 11 to slide out of the slide groove 21, thereby getting rid of the restriction on the drain plug 2 caused by the cooperation of the guide post 1 and the limiting part 22, and realizing the detachable connection and fixation of the drain plug 2 and the drain pipe 1.

[0050] like Figure 6As shown, the inlet 231 of the disassembly guide groove 23 is located on the second side wall 212 of the slide groove 21, and the plane of the second side wall 212 of the slide groove 21 faces the circumference of the drain plug 2. The second side wall 212 is a side wall extending along the length direction in the slide groove 21. There are two second side walls 212, namely an upper second side wall 2121 and a lower second side wall 2122, and the two second side walls 212 are arranged at intervals along the circumferential direction of the drain plug 2. The disassembly guide groove 23 can be located on the upper second side wall 2121, on the lower second side wall 2122, or simultaneously on the first side wall 2121 and the second side wall 2122.

[0051] As a preferred embodiment, the outlet 201 faces downwards during the sliding of the guide post 11 along the groove 21, facilitating water flow. The opening direction of the groove 21 is perpendicular to the opening direction of the outlet 201; the groove 21 opens towards the front, while the outlet 201 opens towards the bottom, with both opening directions perpendicular to each other. To achieve more stable sliding of the drain plug 2 along the drain pipe 1, two grooves 21 are provided, positioned opposite each other on the front and rear sides of the drain plug 2. Correspondingly, two guide posts 11 are also provided opposite each other on the inner wall of the drain pipe 1.

[0052] As a preferred solution, such as Figure 6 As shown, the inlet 231 of the disassembly guide groove 23 is located on the upper second side wall 2121. Since the slide groove 21 opens in the front direction and the inlet 231 of the disassembly guide groove 23 is located on the upper second side wall 2121, the disassembly guide groove 23 can only extend from the front direction to the rear direction, thus making the disassembly guide groove 23 generally clockwise positioned on the side wall of the drain plug 2. Accordingly, if the drain plug 2 needs to be disassembled, the drain plug 2 needs to be rotated clockwise to generate relative sliding with the guide post 11. The above structure makes the process of disassembling the drain plug 2 more in line with the user's usage habits and more convenient for the user.

[0053] The specific structural shape of the disassembly guide groove 23 on the side wall of the drain plug 2 can vary. The disassembly guide groove 23 is generally spirally arranged on the side wall of the drain plug 2, and the outlet 232 of the disassembly guide groove 23 is located at the first end of the drain plug 2, wherein the first end of the drain plug 2 extends into the drain pipe 1. In this embodiment, to facilitate the installation and disassembly of the drain plug 2, the disassembly guide groove 23 has a straight segment 233 extending along the axial direction of the drain plug 2 and a spiral segment 234 connecting the straight segment 233 and the sliding groove 21. The straight segment 233 and the sliding groove 21 are located on opposite sides of the drain plug 2. The sliding groove 21 is located on the front side of the drain plug 2, and the straight section 233 is located on the rear side of the drain plug 2. The sliding groove 21 and the straight section 233 are connected by the spiral section 234. When disassembling the drain plug 2, the drain plug 2 needs to be rotated 180° along the spiral section 234 and then the guide post 11 is slid into the straight section 233 and then slides out through the straight section 233 to disassemble the drain plug 2 from the drain pipe 1.

[0054] The purpose of setting the straight segment 233 is to facilitate the connection between the drain plug 2 and the drain pipe 1, and after the connection is completed, the drain plug 2 slides a distance along the axial direction of the drain pipe 1, and finally rotates into the slide groove 21 through the spiral segment 234.

[0055] Furthermore, such as Figure 5 As shown, to better achieve the cooperation between the straight segment 233 and the guide post 11, the straight segment 233 also has a guide segment 235 near the outlet 232. The size of the groove of the guide segment 235 gradually increases as it approaches the outlet 232. The guide segment 235 has a tapered structure and a large opening size, which facilitates the installation and cooperation between the drain plug 2 and the drain pipe 1.

[0056] In the above embodiments, when the drain plug 2 switches between a draining state and a non-draining state, the drain plug 2 slides relative to the drain pipe 1 in the axial direction. In another embodiment, when the drain plug 2 switches between a draining state and a non-draining state, the drain plug 2 slides relative to the drain pipe 1 in a helical direction. That is, the drain plug 2 is removed from the drain pipe 1 by rotating the drain plug 2.

[0057] Another embodiment of the present invention also discloses a refrigeration device, such as... Figure 7-10 As shown, it includes a housing, a water receiving tray 100 disposed inside the housing, and a drain pipe assembly disposed on the water receiving tray. The drain pipe 1 has a bent section 12 that is fixedly connected to the water receiving tray 100 and a connecting pipe 13 that communicates with the bent section 12. The drain plug 2 is disposed at the outlet of the connecting pipe 13.

[0058] like Figure 8As shown, the connecting pipe 13 is inclined and its height gradually decreases in the direction away from the bend 12. The connecting pipe 13 has an inlet connected to the bend 12 and an outlet opposite to the inlet, and the height of the inlet of the connecting pipe 13 is higher than that of the outlet in the vertical direction. Compared with the connecting pipe 13 that extends horizontally in the prior art, the above-described structure can reduce the accumulation of water in the connecting pipe 13.

[0059] To facilitate the installation and fixation of the drain pipe assembly, the bend 12 is detachably connected to the water receiving tray 100. The bend 12 has a bend body 121 and an annular baffle 122 disposed on the bend body. The water receiving tray 100 is provided with an installation hole adapted to the bend body 121. The size of the installation hole is smaller than the size of the annular baffle 122. The annular baffle 122 is configured to restrict passage through the installation hole. After the drain pipe assembly is installed and fixed, the annular baffle 122 is pressed tightly against the water receiving tray 100. The drain pipe assembly also has a fastener 14 detachably installed and fixed on the bend body 121. After the bend body 121 is installed and fixed, the fastener 14 is attached to the lower surface of the water receiving tray 100.

[0060] After the drain pipe 1 is installed and fixed on the water receiving tray, the bend 12 is installed and fixed by the cooperation of the annular baffle 122 and the fastener 14. The annular baffle 122 and the fastener 14 respectively abut against the upper and lower sides of the water receiving tray 100.

[0061] Specifically, such as Figure 9-10 As shown, the fastener 14 is a retaining ring, and the bent pipe body 121 is provided with an annular retaining groove 123 adapted to the retaining ring. The water receiving tray 100 is provided with an annular clearance groove 101 adapted to the annular baffle 122. After the drain pipe 1 is installed and fixed, the annular baffle 122 is positioned in the clearance groove 101 so that the upper surface of the annular baffle 122 does not protrude from the upper surface of the water receiving tray 100. The annular baffle 122 is pressed and fixed to the bottom of the clearance groove 101.

[0062] The above embodiment discloses a scheme in which the drain pipe 1 is installed and fixed on the water receiving tray. In another embodiment, the drain pipe 1 can also be used on the freezer and directly installed and fixed on the inner liner of the freezer, that is, the drain pipe 1 is directly connected to the compartment of the freezer.

[0063] The above description, based on the embodiments shown in the figures, details the structure, features, and effects of the present invention. The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the figures. Any changes made in accordance with the concept of the present invention, or equivalent embodiments modified to have equivalent changes, that do not exceed the spirit covered by the specification and figures, should be within the protection scope of the present invention.
