Refrigerator with heat preservation drying mechanism

Abstract

The invention relates to a refrigerator with a heat preservation drying mechanism. The refrigerator comprises a refrigeration chamber and a refrigeration mechanism. A heat preservation chamber is arranged on the bottom on the outer side of the refrigeration chamber, phase change heat storage blocks are arranged in the heat preservation chamber, the condensation sections of five or more gravity assisted heat pipes are inserted into the corresponding phase change heat storage blocks, the evaporation sections of the gravity assisted heat pipes extend out of the heat preservation chamber and are respectively inserted into a condensing coil of a condenser, a thin ventilation pipe is arranged in the refrigeration chamber, the two ends of the thin ventilation pipe respectively extend into the heat preservation chamber, one end of the thin ventilation pipe is an air inlet, the other end of the thin ventilation pipe is an air outlet, a micro fan is arranged on the air inlet, the thin ventilation pipe located inside the refrigeration chamber is communicated with a water drainage pipe through a T-branch pipe, and a water outlet of the water drainage pipe extends out of the refrigeration chamber. According to the refrigerator with the heat preservation drying mechanism, the temperature of the heat preservation chamber is kept from 40 DEG C to 50 DEG C. When the temperature of a working medium inside the condensing coil is larger than the temperature of phase change heat storage materials in the heat preservation chamber, the gravity assisted heat pipes work and transfer waste heat to the phase change heat storage materials in the heat preservation chamber; otherwise, the gravity assisted heat pipes are closed.

Description

technical field [0001] The invention belongs to the technical field of home appliance multifunctional refrigerators, and in particular relates to an environment-friendly and energy-saving refrigerator for heat preservation, drying and sterilization by recovering condensed waste heat. Background technique [0002] Under the background of advocating energy saving and environmental protection, reasonable utilization of refrigerator waste heat has been explored in the field of refrigerators, such as using the waste heat of the refrigerator condenser to heat hot water or food and dry clothes. Patent 96112986.7 mentioned the idea of ​​using the waste heat of the refrigerator to heat the incubator, but it did not consider that the higher temperature of the insulated box would affect the cooling efficiency of the refrigerator condenser to a certain extent, and due to the intermittent operation of the refrigerator, the incubator The problem of temperature instability has also not bee...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problems in the comprehensive utilization of waste heat of refrigerators that the temperature of the incubator is unstable and the ambient humidity is high, the drying and sterilization effect of the drying box will be adversely affected and the utilization of waste heat will reduce the refrigeration efficiency of the refrigerator. A refrigerator with a heat preservation and drying mechanism integrating heat preservation, drying and sterilization functions
