Problems solved by technology

[0004] However, in the above-mentioned existing refrigerator, since the air regulator device for the freezer is arranged in front of the air blower, the size of the depth direction of the freezer becomes larger, and the indoor storage volume of the freezer becomes smaller.
In addition, in conventional refrigerators, due to increased air resistance, there is a possibility that the amount of air sent to the freezer may decrease.
In addition, there is also a problem with existing refrigerators. Since the air damper device for controlling the air circulation in the freezer is located in front of the blower, in order to lift the cold air that is cooled by the evaporator and becomes heavier than before cooling to the position where the air flow is adjusted If the air damper of the air damper is higher than the suction port of the air damper at the upper position, air supply is required, therefore, the air blower consumes excess energy only for this, resulting in increased power consumption

Abstract

To provide a well convenient refrigerator having a wider effective internal volume and reduced power consumption. The refrigerator comprises a refrigerating room, a freezing room located under the refrigerating room, one evaporator, one blower for blowing cooled air heat-exchanged with the evaporator, a freezing room damper unit for controlling the blown cooled air to be blown to the freezing room, and a refrigerating room damper unit for controlling the blown cooled air to be blown to the refrigerating room. A cooled air suction port of the freezing room damper unit is located under the rotational center axis of the blower without being overlapped with the blower.

Description

technical field [0001] The invention relates to a refrigerator. technical background [0002] In the existing refrigerator, for example, when the operation of the compressor is stopped, the air damper device for the freezer is opened, and the frost attached to the evaporator is sublimated by the operation of the blower, and at the same time, air is sent to the refrigerator to improve the temperature of the refrigerator. Humidity, so as to keep vegetables and other food moisture to keep fresh refrigerator. [0003] In this existing refrigerator, the air damper device used in the refrigerator compartment is arranged on the place ahead of the air blower (the depth direction of the refrigerator compartment), and the cooling air is blown into the entire freezer compartment. Such a refrigerator is described in, for example, JP-A-2001-241825. [0004] However, in the above-mentioned conventional refrigerator, since the damper device for the freezer compartment is arranged in fron...
