Description

Technical Field

[0001] This utility model relates to the technical field of drainage pipes, and in particular to a push-pull type anti-clogging inner tank drainage pipe structure. Background Technology

[0002] Refrigerators typically have a drain pipe at the bottom of the inner liner to facilitate the timely drainage of internal condensate. Usually, when draining, items above the drain pipe need to be removed, and then the drain plug needs to be removed to drain the water. For inner liner structures with internal shelves, it is difficult to remove and put in the drain plug. In addition, because the items stored inside the refrigerator are more complex, debris can easily be discharged into the pipe during the drainage process, causing blockages.

[0003] The existing Chinese utility model patent with application number CN201120189552.3 relates to the structure of the drain pipe of a freezer, including an S-shaped pipe, a straight pipe and a water trap, which can effectively ensure the cooling effect.

[0004] However, the above-mentioned device does not have the ability to control the drainage of the inner tank in actual use, and it is easy for debris to enter the pipe. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a push-pull anti-clogging inner tank drain pipe structure that improves the installation stability of the pipe at the drain outlet through a fixed structure and facilitates the control of the opening and closing of the drain pipe through a connecting structure, thereby improving the practicality of the device.

[0006] This utility model discloses a push-pull anti-clogging inner tank drain pipe structure, including a fixed structure and a connecting structure, with the connecting structure installed on the fixed structure. The fixed structure improves the installation stability of the pipe at the drain outlet, while the connecting structure facilitates the control of the opening and closing of the drain pipe, thus improving the practicality of the device.

[0007] Preferably, the fixing structure includes a drain pipe and a flange structure. The upper edge of the drain pipe is provided with a flange structure, and the bottom of the drain pipe is connected to a water outlet connector. The flange structure on the upper surface of the drain pipe facilitates the fixing of the drain pipe to the foaming box, reduces the protrusion or depression of the upper surface of the drain pipe relative to the upper surface of the foaming box, and improves the stability of the structure.

[0008] Preferably, the connecting structure includes a drain plug, with a support plate at the top edge of the drain plug, and multiple sets of annular rubber sheets evenly arranged in the middle and lower parts of the side of the drain plug. The drain plug, in conjunction with the fixing structure, seals the upper end face of the drain pipe, thereby controlling the drainage function of the drain pipe. The support plate at the top edge of the drain plug rests on the flanged structure of the upper end face of the drain pipe, preventing the drain plug from falling into the drain pipe from the inlet end. The annular rubber sheets in the middle and lower parts of the drain plug ensure contact between the rubber sheets and the inner wall of the drain pipe after the drain plug is inserted into the drain pipe, preventing the drain plug from shaking and falling off during use, thus affecting the normal use effect of the drain plug and improving the practicality of the device.

[0009] Preferably, it also includes a U-shaped groove. One side of the flanged structure at the top of the drain pipe extends into the drain pipe to partially cover the upper port of the drain pipe. A U-shaped groove is provided on the upper side of the drain pipe plug. The part of the flanged structure located at the inner port of the drain pipe can be inserted into the U-shaped groove on the drain pipe plug. The drain pipe plug can slide at the port of the drain pipe. By sliding the drain pipe plug left and right at the port of the drain pipe, the U-shaped groove on the drain pipe plug slides to the part of the flanged structure located at the upper port of the drain pipe, thereby removing the seal between the drain pipe plug and the other side of the upper port of the drain pipe, thus draining the condensate in the box. The process of sealing and releasing the drain pipe port by directly sliding the drain pipe plug is simple to operate, reducing the labor intensity of the operator. In environments where there are debris or shelves on the upper side of the drain pipe, drainage and sealing can be achieved quickly, and the position of the drain pipe plug can be maintained to keep the drainage state, thus improving the practicality of the device.

[0010] Preferably, the device also includes limiting the processing depth of the U-shaped groove according to the actual usage environment; by limiting the processing depth of the U-shaped groove, the open gap area between the drain plug and the drain pipe is limited during the sliding process of the drain plug, thereby limiting the size of the garbage entering the drain pipe, preventing blockage inside the drain pipe, and improving the practicality of the device.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the fixed structure improves the installation stability of the pipe at the drain outlet, and the connection structure facilitates the control of the opening and closing of the drain pipe, thus improving the practicality of the device.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The connection structure shown is installed on the fixed structure;

[0022] First, when drainage is needed, manually push the drain plug 3 so that the U-shaped groove 8 on the drain plug 3 slides to the part of the flange structure 2 located at the upper port of the drain pipe 1, so that the drain plug 3 and the other side of the upper port of the drain pipe 1 are no longer sealed, thereby draining the condensate in the box 7. When continuous drainage is needed, adjust the position of the drain plug 3 on the drain pipe 1 to leave a drainage gap.

[0023] The fixing structure includes a drain pipe 1 and a flange structure 2. The upper edge of the drain pipe 1 is provided with the flange structure 2, and the bottom of the drain pipe 1 is connected to a water outlet connector.

[0024] The connecting structure includes a drain plug 3, with a support plate provided on the top edge of the drain plug 3, and multiple sets of annular films evenly provided on the middle and lower sides of the drain plug 3.

[0025] It also includes a U-shaped groove 8. One side of the upper flange structure 2 of the drain pipe 1 extends into the drain pipe 1 to partially cover the upper port of the drain pipe 1. A U-shaped groove 8 is provided on the upper side of the drain pipe plug 3. The part of the flange structure 2 located at the inner port of the drain pipe 1 can be inserted into the U-shaped groove 8 on the drain pipe plug 3. The drain pipe plug 3 can slide at the port of the drain pipe 1.

[0026] It also includes limiting the machining depth of the U-shaped groove 8 according to the actual usage environment;

[0027] The fixed structure improves the installation stability of the pipes at the drainage outlet, and the connection structure facilitates the control of the opening and closing of the drainage pipes, thus improving the practicality of the device.
