Pulse heating anti-blocking refrigerator

Abstract

The invention relates to a refrigerator, in particular to a pulse heating anti-blocking refrigerator. The pulse heating anti-blocked refrigerator comprises a compressor, a condenser, an evaporator, a capillary tube, an electric heater, a magnetic valve and a drying filter, wherein the compressor, the condenser, the magnetic valve, the drying filter, the capillary tube and the evaporator are successively connected in a closed loop manner. The pulse heating anti-blocking refrigerator has the advantages that: after the pulse heating anti-blocked refrigerator is used, organic matter impurities, such as oil stain and the like can be heated and blown out under high temperature, and blocking can be prevented, a refrigerating system is not needed to be opened, blocking can be removed, maintenance time and materials can be saved, control, manufacture and installation are simple, and production and operation are easy.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a pulse heating anti-blocking refrigerator. Background technique [0002] During the operation of the refrigerator, the impurities inside the refrigeration system will also circulate together with the refrigerant. In order to prevent impurities from clogging the capillary, the refrigeration device installs a dry filter to filter impurities in front of the capillary, but some small impurities and oil can still pass through. The filter drier flows to the capillary. Impurities in the refrigeration system of refrigerators are generally a combination of oil, metal shavings, molding sand, etc., which are easy to accumulate and block in the front end of the capillary. Now the common way to deal with blockage is: first tap the capillary lightly, try your luck, and see if the blocked impurities can pass through the blockage during vibration, if not, open the refrigeration system, blow the dirt with high...

Problems solved by technology

Now the common way to deal with blockage is: first tap the capillary lightly, try your luck, and see if the blocked impurities can pass through the blockage during vibration, if not, open the refrigeration system, blow the dirt with high-pressure nitrogen, and replace the filter device , this method needs to let go and replace the refrigerant, refrigeration oil, and replace the filter device. This method is complicated to operate, labor-intensive and time-consuming, and wastes materials.
