PURPOSE:To prevent frosting on a blower by providing a divider between a refrigerating chamber and cold storage chamber with a return flow channel of cold air from the refrigerating chamber, cold storage chamber, etc., and a direction changing means that is provided downstream of a cooler and matches the sucking-out port of this return channel. CONSTITUTION:By rotating a blower 6 cold air is sent into an air channel space C, and the cold air flows out into respective storage chambers as shown by the arrow marks, and the cold air that enters a refrigerating chamber B goes to a cooler 3 through a return flow channel 8b and the cold air that enters a cold storage chamber D goes to the cooler 3 through a return flow channel 8a respectively. And, after the return air from the cold storage chamber D is cooled through the cooler 3, it collides with the return air from the refrigerating chamber B that comes out from the return flow channel 8b through the cooler 3 by a direction changing plate 4a that is installed to match the position of the sucking-out port of the return flow channel 8a and both return air mix together so that the return air is further cooled and sucked into a blower 6. With this arrangement, the temperature of the blower 6 is always higher than that of the sucked air and frosting never occurs on it. |
