Abstract

The present invention provides a refrigerator capable of reducing power consumption and having a heat-insulating partition wall capable of increasing the volume of the tank. The refrigerator according to the present invention is a refrigerator (1) for refrigerating or freezing an inner foodstuff by cold air generated by an evaporator (7). The refrigerator comprises an insulating case (10) (10) filled with foamed thermal insulating material (10p) between the outer box (10s) and the inner box (10u); a frozen temperature chamber(5) and a vegetable chamber (6) provided with an insulating case(10), and an insulating partition wall (29) provided with an insulating space (29d) thereof; an vaccum insulating material (32) configured inside the insulating wall (29). When viewed from the front, the lateral width of the vacuum insulating material (32) is larger than the lateral width of the evaporator (7); when viewed from the front or the above, a cool air returning port(29a) into which the cool air after cooling the vegetable compartment (6) is sucked is located on the projection surface of the vacuum heat insulating material (32).

Description

technical field [0001] The present invention relates to refrigerators. Background technique [0002] In the past, as a method to prevent global warming, in order to achieve carbon dioxide (CO 2 ) emission suppression to promote energy saving in various fields. In electrical appliances in recent years, especially refrigerators, attention has been paid to the improvement of thermal insulation performance from the viewpoint of reducing power consumption. [0003] In general refrigerators, between an outer case made of a thin steel plate and an inner case made of resin, the partition walls of the respective storage rooms are filled with a foam insulating material such as rigid urethane foam to form an insulated box. And, on the other hand, there is always a need to increase the internal volume of the refrigerator without increasing the external dimensions of the refrigerator. [0004] In recent years, there have been increasing cases of using vacuum insulation materials havin...
