Air-cooled refrigerator

Abstract

The invention provides an air-cooled refrigerator which comprises a refrigerator body, a water discharge pipeline, a controlled atmosphere membrane component and an air extracting pump, wherein a storing space and a cooling space are formed in the refrigerator body; a storage container is arranged in the storing space; a controlled atmosphere fresh-keeping space is formed in the storage container; the water discharge pipeline is mounted on the refrigerator body, communicated with the cooling space and used for discharging water dropped down from an evaporator out of the cooling space; the controlled atmosphere membrane component is configured to enable more oxygen, relative to nitrogen, in the air flow of the around space permeates a controlled atmosphere membrane to enter an oxygen-enriched gas collecting cavity; the air extracting pump is used for extracting gas permeating the oxygen-enriched gas collecting cavity to be discharged out of the storage container through an air extracting pipeline and an air exhaust pipeline; the air exhaust pipeline is configured to enable gas permeating the oxygen-enriched gas collecting cavity to carry out heat exchange with the water discharge pipeline directly or indirectly after flowing out of the air extracting pump. According to the air-cooled refrigerator, the energy of gas discharged through the air extracting pump is utilized to dissolve residual ice at the inlet of the water discharge pipeline due to that the temperature of the gas is higher than that at the inlet of the water discharge pipeline, so that the water discharge pipeline is prevented from being blocked, and the energy is fully utilized.

Description

technical field [0001] The invention relates to the technical field of refrigerator storage, in particular to an air-cooled refrigerator. Background technique [0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature and cold state. The refrigerator may include an air-cooled refrigerator, and a drain pipe is installed under the evaporator of the air-cooled refrigerator to facilitate the defrosting water dripping from the evaporator into the evaporator in the compressor compartment. However, in the actual defrosting process, some frost on the evaporator does not completely melt into water and falls to the bottom of the evaporator, and gathers near the drain (that is, the inlet of the drain pipe). Since the defrosting heating wire is placed in the lower part of the evaporator, almost all the heat generated during heating is transferred to the evapo...

AI Technical Summary

Problems solved by technology

Since the defrosting heating wire is placed in the lower part of the evaporator, almost all the heat generated during heating is transferred to the evaporator, and it is difficult to heat the drain below it.

When the evaporator is working again after defrosting, because the temperature around the evaporator drops below 0°C rapidly, this part of the residual ice will freeze again and slowly accumulate into a large piece of ice, which will block the drain, and when defrosting again , the dripping defrosting water cannot be discharged to the evaporator through the drain pipe, but will flow directly to the freezer, causing users to complain
