Drain pipe component for cold cabinet and cold cabinet with same

Abstract

The invention discloses a drain pipe component for cold cabinet and a cold cabinet with the same. The drain pipe component for the cold cabinet comprises an inner water pipe, an outer water pipe and a ventilating valve, wherein inner water pipe and the outer water pipe are connected; the ventilating pipe is arranged between the inner water pipe and the outer water pipe; and the ventilating valve is closed in an airtight mode when a door body of the cold cabinet is closed, and is opened when the door body of the cold cabinet is opened so as to allow external air to enter the cold cabinet through the ventilating valve. According to the drain pipe component for the cold cabinet provided by the embodiment of the invention, and the ventilating pipe is arranged between the inner water pipe and the outer water pipe, the ventilating valve is opened when the door body of the cold cabinet is opened, the conduction of the external part and the inner part of the cold cabinet can be realized, the inner and outer pressure of the cold cabinet are balanced, and the problem that the door body of the cold cabinet is difficult to be opened because the air pressure in the cold cabinet is too low is solved; and the ventilating valve is closed in the airtight mode when the door body of the cold cabinet is closed, cold air can be prevented from leaking out, and energy consumption is lowered.

Description

technical field [0001] The invention relates to the technical field of preparation of household electrical appliances, and more particularly, to a drainpipe assembly for a refrigerator and a refrigerator having the same. Background technique [0002] At present, for products with a capacity of more than 200L, after a period of operation, since the inside of the freezer is a closed space, the external air pressure of the box is greater than the internal air pressure after cooling, and a pressure difference occurs between the inside and outside of the door, and the door of the freezer is opened when the pressure difference between the inside and outside air pressure is large. More force is required or the door cannot be opened in extreme cases. [0003] In addition, the current outlet pipe has no exhaust structure, which cannot balance the internal and external pressure, resulting in the door not being able to open normally, resulting in market complaints.

[0002] At present, for products with a capacity of more than 200L, after running for a period of time, since the inside of the freezer is a closed space, the external air pressure of the box is greater than the internal air pressure after cooling, and a pressure difference occurs between the inside and outside of the door, and the door of the freezer is opened when the pressure difference between the inside and outside air pressure is large. More force is required or the door cannot be opened in extreme cases

[0003] In addition, the current outlet pipe has no exhaust structure, which cannot balance the internal and external pressure, resulting in the door not being able to open normally, causing market complaints
