Blower shielding device and refrigerator

Abstract

The invention discloses a blower shielding device for a refrigerator. The refrigerator comprises a box body, a compressor, an evaporator and a blower. A target refrigeration room is defined in the boxbody. An air flue introduced in the target refrigeration room is arranged at the rear part of the target refrigeration room. The compressor is arranged at the bottom of the box body. The evaporator is arranged in an evaporation cavity of the box body, and can provide cooling capacity for the target refrigeration room. The blower is arranged in a blower cavity above the evaporator, and is used forintroducing cold air from the evaporator in the air flue. The blower comprises blades and a driving shaft driving the blades to rotate. The blower shielding device comprises a blower cover covering the peripheries of the blades. A thread section is arranged on the driving shaft. The blower cover is matched with the thread section. When the blower is turned off, the evaporator cavity is disconnected with the air flue by the blower cover. When the blower is turned on, under the driving of the thread section, the blower cover moves in the axial direction of the driving shaft to allow the evaporator cavity to communicate with the air flue by means of the blower cavity.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a fan shielding device and a refrigerator. Background technique [0002] In the prior art, refrigerators generally refer to single-door, double-door and double-temperature, three-door and three-temperature, cabinet-type multi-door refrigerators, etc., generally have an independent freezer and the outer door of the freezer, so that they can be separated according to different storage temperatures. store. The refrigeration principle of this refrigerator-freezer is divided into direct cooling and air cooling. Direct-cooling refrigeration systems often use solenoid valves to control the flow of refrigerant, and supply refrigerant to the evaporators of each refrigerating (freezing) room to cool each space to the required temperature. Air-cooled refrigerators and freezers need to set up corresponding air ducts to supply air to each space. [0003] Due to the high efficiency and f...

Disadvantages; there is a risk of damage to the device, and the refrigerator cannot be used when defrosting

[0005] At present, the refrigerating evaporator and the refrigerating space in the dual-system refrigerating-freezing refrigerator are always connected through the air duct, which makes the refrigerating temperature fluctuate greatly. The existing refrigerating micro-channel technology uses the motor to control the turntable to send air to the corresponding air outlet of the refrigerating system. The use of motor drive not only consumes power The quantity is large, and the cost of the motor itself is high; the motor will generate noise during rotation, which runs counter to the low noise required by the refrigerator
