Description

Technical Field

[0001] The invention belongs to the technical field of refrigerators, and in particular relates to a drainage pipe anti-blocking tool for refrigerators. Background Art

[0002] In order to smoothly discharge the condensed water in the refrigerator box out of the refrigerator, the refrigerator with an upper storage and lower freezing structure usually uses a drain pipe structure. Therefore, the drain pipe is connected to the refrigerator box and connected to the outside world, so that the condensed water in the refrigerator box can be discharged to the outside world through the drain pipe. Therefore, during the production process of the refrigerator, if the foaming liquid leaks into the drain, it will cause the drain pipe to be blocked, affecting the drainage function of the drain pipe; in addition, the drain pipe of the upper storage and lower freezing refrigerator starts from the refrigerator box and ends at the bottom of the line body, and passes through the freezing box. The general drain pipe is close to the freezing box and maintains a certain standard distance; if the drain pipe is deformed due to the pressure of the foaming liquid during the foaming process of the box, and the distance between the drain pipe and the freezing box is less than the standard distance, it will cause the problem of ice inside the drain pipe and affect the drainage function of the drain pipe. The blockage of the drain pipe will eventually lead to the scrapping of the refrigerator or the repair of the refrigerator. Therefore, a drain pipe anti-blocking device is needed to prevent the drain pipe from being deformed under pressure and causing ice.

[0003] The present invention arranges stepped sections at both ends of the connecting rod body, and respectively closely cooperates with a spring guide head and a limit block, so as to avoid deformation of the drain pipe during the foaming process of the box body, so that the distance between the drain pipe and the freezing box body is smaller than the standard distance, causing ice to form inside the drain pipe, and facilitating disassembly and installation. The length of the connecting rod body can be adjusted according to different models of refrigerators, and the invention has the effect of strong versatility. Summary of the invention

[0004] The purpose of the present invention is to provide a drain pipe anti-blocking tool for a refrigerator. By arranging step sections at both ends of a connecting rod body and tightly fitting with a spring guide head and a limit block respectively, the problem of drain pipe blockage caused by foaming liquid leaking into the drain during the production process of the existing refrigerator, and deformation of the drain pipe due to the pressure of the foaming liquid during the foaming process of the box body, and the distance between the drain pipe and the freezing box body being less than the standard distance, causing ice to form inside the drain pipe, is solved.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is a refrigerator drain pipe anti-blocking tool, comprising a connecting rod body;

[0007] Both ends of the connecting rod body shrink toward the middle to form a stepped section; the side surface of one stepped section is tightly matched with a spring guide head, which is designed as a cylindrical structure and can be bent; the side surface of the other stepped section is tightly matched with a limit block, which is a circular ring structure;

[0008] The connecting rod body penetrates the inner wall of the drain pipe in the refrigerator body; a water pipe joint is installed at one end of the drain pipe; the drain pipe and the water pipe joint are filled with box foaming liquid around the drain pipe;

[0009] The spring guide head part penetrates into the inner wall of the water pipe joint and changes direction along with the inner cavity of the water pipe joint; the connecting rod body is a hollow circular tube structure.

[0010] Furthermore, the connecting rod body is made of hard aluminum alloy and cannot be bent. It is penetrated into the drain pipe by anti-blocking tooling to fill the inner cavity of the drain pipe to prevent the foaming liquid of the box from entering the drain pipe and blocking the drain pipe.

[0011] Furthermore, the distance between the peripheral side surface of the connecting rod body and the inner wall of the drain pipe is greater than 1 mm, which facilitates the detachment of the tooling from the drain pipe when the limit block is pulled out.

[0012] Furthermore, a magnetic component is fixedly mounted on one end of the limit block; the magnetic component is adsorbed on the refrigerator base to prevent the tooling from falling off.

[0013] Furthermore, the magnetic component is a magnet.

[0014] The present invention has the following beneficial effects:

[0015] 1. The present invention fills the inner cavity of the drain pipe with the connecting rod body, thereby preventing the foaming liquid in the box from entering the drain pipe and blocking the drain pipe. It also increases the overall hardness of the drain pipe, avoids the problem of compression deformation of the drain pipe, and eliminates the phenomenon of icing of the drain pipe.

[0016] 2. The present invention has a spring guide head that is tightly matched with the side surface of the step section, which can change the direction along the inner cavity of the water pipe joint and is suitable for bending pipes; a magnetic component is fixedly installed at one end of the limit block and adsorbed on the refrigerator base, which can prevent the tooling from falling off.

[0017] 3. The present invention has a spacing of more than 1 mm between the side surface of the connecting rod body and the inner wall of the drain pipe, which facilitates the detachment of the tooling from the drain pipe when the limit block is pulled out, thereby preventing the drain pipe from deforming during the foaming process of the box body, making the distance between the drain pipe and the freezer box smaller than the standard distance, causing ice to form inside the drain pipe, facilitating disassembly and installation, and the length of the connecting rod body can be adjusted according to different models of refrigerators, thus having a strong versatility.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
