Description
Technical field
The utility model belongs to refrigerator technical field, especially a kind of derect refrigerated refrigerator refrigerating chamber antifrost device.
Background technology
As everyone knows, common on the market derect refrigerated refrigerator in use all can in a large amount of frost layer of the surface condensation of evaporimeter.When frost layer is very thin, not fairly obvious to the Heat Transfer Influence of evaporimeter, but after whole evaporimeter is encased by frost, the heat-transfer capability of evaporimeter will be had a strong impact on when frost layer progressive additive.
After evaporator surface frosting, heat transference efficiency degradation, causes and only has condenser zone local temperature low, and cooling compartment temperature is difficult to decline.The temperature controller of refrigerator can't detect the temperature decline of local, then make compressor continuous service, can cause the shortening in waste of energy and compressor life-span like this.And the food pressed close near evaporimeter also can freeze.After having part food in refrigerating chamber, inner air convection effects declines, and cause temp. in refrigerating chamber skewness, the food near high-temperature area is easily putrid and deteriorated, and the food of low temperature part easily freezes.
This thickness frost relies on the air free convection slowly in refrigerating chamber not melt, and therefore, traditional direct cooling refrigerator adopts manual defrosting usually, and namely monthly need shutdown defrosting once, it is very inconvenient to use.As do not defrosted for a long time, then frost is condensed in evaporator surface, seriously reduces heat transference efficiency, causes compressor to work long hours and internal temperature of refrigerator does not still decline, and virtually adds the consumption of electric power, and shortens the life-span of compressor.
Through retrieving patent document disclosed in discovery one section, concrete disclosure is as follows:
Patent document: a kind of refrigerator of the device frosting that avoids evaporating, (notification number CN204141922U), the evaporimeter comprising refrigerating chamber, refrigerating chamber, compressor and be connected with compressor, arrange accommodation chamber in the outside top of refrigerating chamber, the end of this evaporimeter extends to accommodation chamber; Be arranged on the radiator in accommodation chamber and fixing fan on a heat sink, and this radiator muff-joint is connected on the end of this evaporimeter; Be fixedly installed heater on a heat sink; Set temperature sensor on the interior plate of refrigerating chamber, the interior plate of accommodation chamber is fixedly connected with control circuit board, and this temperature sensor and heater are all electrical connected with control circuit board.
Find through contrast, there is complex structure in above-mentioned documents, has relatively big difference with present patent application in technical scheme.
