Water drain pipe joint equipment for refrigerator and refrigerator provided with water drain pipe joint equipment

Abstract

The invention discloses water drain pipe joint equipment for a refrigerator; the refrigerator comprises a first chamber and a second chamber positioned below the first chamber; and the water drain pipe joint equipment is arranged in the second chamber and is connected between a first water drain pipe arranged in the first chamber and a second water drain pipe arranged in the second chamber. The water drain pipe joint equipment comprises a first pipeline, a second pipeline and a third pipeline; the first pipeline extends vertically, and the upper end of the first pipeline is communicated with the first water drain pipe; the second pipeline extends obliquely, and the upper end of the second pipeline is open to form a dredge mouth; the lower end of the first pipeline is communicated with the side wall of the adjacent upper end of the second pipeline; the third pipeline is arranged vertically; the upper end of the third pipeline is communicated with the lower end of the second pipeline; and the lower end of the third pipeline is communicated with the second water drain pipe. According to the water drain pipe joint equipment of the embodiment provided by the invention, when stoppage or unexpected freeze appears in the refrigerator, dredging can be realized through the dredge mouth, so that the refrigerator is convenient to maintain and low in maintenance cost; and the water drain pipe joint equipment is simple in structure and convenient to install. In addition, the invention also discloses the refrigerator provided with the water drain pipe joint equipment.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a drain pipe joint device used in a refrigerator and a refrigerator having the same. Background technique [0002] The drain pipe joints of the traditional top-cooler and bottom-free frost-free refrigerators are all built-in. The drain pipe joint of this structure is assembled in the pre-installation process of the tank, and the tank is hidden in the foam layer after foaming. And when this built-in drain pipe joint is assembled, the joint is first fixed on the freezer tank by hot melt adhesive, and simultaneously the drain pipe and the joint are also fixed and sealed with hot melt adhesive. [0003] At present, the built-in drainage pipe joint has three disadvantages: 1. It cannot be repaired; 2. It cannot be dredged; 3. It is expensive. The above three shortcomings have always been the difficulties in the industry for top-freezing and bottom-covering air-cooled refrigera...

Problems solved by technology

[0003] At present, the built-in drainage pipe joint has three disadvantages: 1. It cannot be repaired; 2. It cannot be dredged; 3. It is expensive

The above three shortcomings have always been the difficulties in the industry for top-freezing and bottom-covering air-cooled refrigerators.

When the built-in drain pipe and the joint are poorly sealed, after the refrigerator foams, the foam material seeps into the space between the drain pipe and the joint, resulting in blockage of the drain pipe, and the refrigerator can only be scrapped, resulting in waste due to non-repairability and increased manufacturing costs

Even if the foaming process is good, due to the different environment, humidity and usage methods of the refrigerator, when the refrigerator is dirty and blocked, the refrigerator can only be scrapped or repaired destructively, and the cost is very high

In addition, when there is an abnormality in the refrigerator and the drainpipe freezes, you can only cut off the power supply and let the ice in the drainpipe melt naturally, which is very inconvenient
