Drain pipe component and refrigerator

Abstract

The invention provides a drain pipe component and a refrigerator. The drain pipe component comprises a pipe body, a floating valve and a baffle ring, wherein the pipe body is provided with a drain channel, an outlet of the drain channel is provided with a limit member, the floating valve is arranged in the drain pipe and can move up and down between the limit member and the baffle ring and the baffle ring is arranged at the inlet of the drain channel. According to the drain pipe component provided by the invention, the drain channel is opened or closed by moving the floating valve up and down between the baffle ring and the limit member so that the floating valve moves upwards to open the drain channel when the drain pipe component needs to drain water, therefore water produced by the defrosting of the refrigerator can be effectively drainage, the drain channel can be closed by moving the floating valve downwards when the drain pipe component does not need to drain water, and the outside heat load can be effectively prevented from entering a container of the refrigerator through the drain channel; furthermore, the drain pipe component is simple in structure, convenient to install, reliable to use and low in cost.

Description

technical field [0001] The present invention relates to the field of refrigeration equipment, and more specifically, to a drain pipe assembly and a refrigerator including the drain pipe assembly. Background technique [0002] At present, in the air-cooled refrigerators on the market, when the refrigerating compartment of the refrigerator, such as the cooling energy emitted by the surface of the finned evaporator in the freezing chamber, circulates to all corners of the freezing chamber, and after a certain period of time, the temperature in the freezing chamber tends to be stable, and the defrosting The heater works to defrost, so that the frost and small ice crystals on the surface of the finned evaporator turn into water, and flow to the outside water tray through the drain pipe channel at the bottom of the refrigerator; when the refrigerator is not in the defrosting state At this time, the external heat load will flow into the tank through the drain pipe. In this way, on ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned technical solutions can achieve the purpose of reducing the heat load from the outside to enter the refrigerator tank through the drain pipe to a certain extent, but the above-mentioned technical solutions also have the following disadvantages: The way of the drain pipe, the installation of the middle drain pipe is inconvenient, and a large force is required to fix the middle drain pipe. There is an extra intermediate drain pipe, which increases the cost of the whole machine; for the method of placing a rubber plug at the outlet of the drain pipe, although the plug is small in size, the plug is also prone to fall after installation Phenomenon; for the method of directly making the outlet of the drain pipe smaller, it is easy to cause the drain pipe to be blocked (ice blocked) due to the reduced diameter of the drain pipe
