Background technology
Refrigerator, is a kind of refrigeration plant that keeps constant low temperature, conventionally by compressor, and evaporimeter and condenser group
Become refrigeration system, refrigerator energy long-play keeps casing in low-temperature condition, but along with refrigerator long-play there will be more and more thicker frost layer, frost layer can affect the work of compressor, affect refrigerating efficiency, conventionally the disconnection of refrigerator power supply need to be quit work and makes its defrost, can affect the refrigerating efficiency of refrigerator.
Summary of the invention
In order to overcome the problems referred to above, the invention provides a kind of defrosting device, this device can carry out timing defrost to refrigerator and guarantee that refrigerator normally moves.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of apparatus for removing refrigerator frost, it is characterized in that by screw compressor, evaporimeter, condenser, timer, the time relay, auxiliary reclay, cross valve, discharge outlet, expansion valve, refrigerating chamber forms, timer connect hours relay normally-closed contact, the time relay is connected with auxiliary reclay, auxiliary reclay connects cross valve solenoid, four mouths of cross valve respectively with screw compressor, evaporimeter, condenser connects, evaporimeter is connected with condenser by expansion valve, refrigerating chamber is connected with discharge outlet, during normal work, refrigerating chamber refrigeration, when refrigerator runs to certain hour, timer work makes auxiliary reclay action be communicated with cross valve solenoid, make cross valve change compressor, gas flow between evaporimeter and condenser, make refrigerating chamber heat defrost and the water after defrost is discharged by discharge outlet, after defrost a period of time, the time relay disconnects, refrigerator is got back to normal refrigerating state.
The invention has the beneficial effects as follows that refrigerator can reduce white formation regularly to refrigerating chamber heating, improves operational efficiency.
