Abstract

The invention provides a refrigerator, which includes a box body, an evaporator and a blower fan. The box body defines a cooling chamber located below and at least one storage compartment above the cooling chamber. The evaporator is arranged in the cooling chamber, and the air supply A fan is located downstream of the evaporator in the airflow path and is configured to induce cooling airflow into the at least one storage compartment. In the refrigerator of the present invention, the cooling chamber is located in the lower part of the cabinet, which occupies the lower space in the cabinet, and the cooling chamber can be used to make way for the compressor cabin, and the storage compartment does not need to make way for the compressor cabin, so as to avoid freezing in the existing scheme The room needs to give way to the compressor cabin, which leads to the problem of abnormal shape in the freezer, so as to ensure the storage volume of the freezer; in addition, by setting the air supply fan downstream of the evaporator, the airflow cooled by the evaporator is accelerated to the storage compartment Flow, to ensure the cooling effect of the refrigerator.

Description

technical field [0001] The invention relates to the technical field of home appliances, in particular to a refrigerator with double air supply fans and an air supply control method thereof. Background technique [0002] In existing refrigerators, the freezer compartment is generally located at the lower part of the refrigerator, the evaporator is located at the rear of the freezer compartment, and the compressor cabin is located at the rear lower part of the freezer compartment. depth. [0003] Moreover, in the prior art, the cooling airflow after exchanging heat with the evaporator is driven by a single fan, and the cooling airflow is divided into multiple paths and respectively directed to the refrigerating chamber, freezing chamber, and temperature-changing chamber in the refrigerator. The temperature in each room is controlled by controlling the opening and closing time of each air duct, but this temperature control method is often not precise enough, so that the temper...
