Abstract
The invention discloses a refrigerator, comprising a box body, a refrigerating chamber and a freezing chamber, wherein the refrigerating chamber is arranged in the box body and comprises an evaporator and a fan, the evaporator is arranged in the refrigerating chamber and used for dividing the refrigerating chamber into an air channel and a refrigerating space, and the fan is arranged in the air channel so as to carry out forced convection on air flowing out from the evaporator; and the freezing chamber is arranged in the box body. According to the refrigerator disclosed by the embodiment of the invention, heat exchange can be carried out on the refrigerating chamber from both two sides of the evaporator towards the air channel and the refrigerating space, so that the heat transfer efficiency is increased. In addition, because the evaporator is not in direct contact with a box container, the refrigeration amount is not conducted to a foaming layer, so that refrigeration leakage is reduced and energy consumption is also reduced. Meanwhile, the evaporator is directly utilized as a component part for isolating the air channel, therefore, the traditional interlayer for isolating the air channel and the refrigerating space is omitted, the material is saved, and the cost is lowered.
Description
Technical field
The present invention relates to art of refrigeration units, especially relate to a kind of refrigerator.
Background technology
Household electric refrigerator can be divided into two types according to heat transfer type, and a kind of is air-cooled; A kind of is direct-cooling type.Wind cooling refrigerator be air after the finned evaporator heat exchange, through fan forced convection and storeroom air heat exchanging tampering, its advantage is not need artificial defrost, storage temperature even; Direct cooling refrigerator is evaporimeter and storeroom air transmitted heat exchange, and its advantage is with low cost.
Because of taking into account cost and storage temperature, have frostless direct cooling refrigerator in the market, promptly the back at the direct cooling refrigerator refrigerating chamber adds air channel 1 ' and fan 2 ', particularly, as shown in Figure 2, evaporimeter 3 ' is for tube-in-sheet evaporator and be placed in the foaming layer 4 ', limits between the postnotum of air channel 1 ' by interlayer 5 ' and refrigerating chamber to form, and fan 2 ' is located in the air channel with to the formation of the air in refrigerating chamber heat convection.Yet there is following defective in this kind scheme: at first, evaporimeter 3 ' directly contacts with the foaming layer 4 ' of refrigerator, easily cold is conducted to foaming layer 4 ' thus, causes heat transfer efficiency lower; Secondly, evaporimeter 3 ' only can flow out air and conduct convection current towards a side of refrigerating chamber direction, and heat transfer efficiency is further relatively lower.
