Parallel cooling refrigerator

Abstract

The present invention discloses one kind of parallel cooling refrigerator and belongs to the field of cooling-air circulating technology for refrigerator. The refrigerator includes freezing chamber, cold storage chamber installed parallelly to the freezing chamber, partition board to separate the freezing chamber and the cold storage chamber, evaporator to form cooling circulation, separating board to separate the heat exchange space of the evaporator into two parts, freezing chamber cold air passage to feed partial cold air into the freezing chamber, cold storage chamber cold air passage to feed other cold air into the cold storage chamber, and blower for the forced circulation of cold air. The present invention has raised cooling effect, saving in power, raised cold storage chamber cooling speed and maximized cold storage chamber volume.

Description

technical field [0001] The present invention is an invention and creation related to the cooling gas cycle of a refrigerator. In particular, it relates to a side-by-side cooling type refrigerator which independently cools a freezer compartment and a refrigerator compartment of the refrigerator. Background technique [0002] A refrigerator is a device that uses the repeated compression-condensation-expansion-evaporation cooling cycle of a refrigerant (refrigerant) to lower the temperature inside the refrigerator and keep food fresh for a certain period of time. It is a necessary household appliance in life. [0003] The refrigerator is a compressor that raises the temperature and pressure of a low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant; a condenser that condenses the refrigerant flowing out of the compressor; An expansion valve that decompresses the outflowing refrigerant; evaporates the low-pressure ref...

AI Technical Summary

Problems solved by technology

At this time, the cold air is also sent to the freezer (1) where the temperature in the box has been satisfied, that is, an unnecessary supply of cold air is generated, and therefore, unnecessary power waste occurs.

[0013] Secondly, in refrigerators with old-fashioned structures, the amount of cold air distributed to the refrigerating chamber through the evaporator (4) is small, so there is a problem that the cooling rate of the refrigerating chamber is relatively slower than that of the freezing chamber (1)

[0014] Even if the set temperature of the refrigerator compartment (2) is higher than that of the freezer compartment (1), the cooling rate of the freezer compartment must be slower than that of the freezer compartment due to the small flow of cold air.

[0015] At the same time, in the old-fashioned refrigerator, due to the thickness of the evaporator (4) installed on the inner wall of the freezer compartment (1), the internal volume of the freezer compartment is reduced, so there is also the problem of low space utilization efficiency.
