Dynamic uniform draught fan cover plate component for household electrical appliance and household electrical appliance

Abstract

The invention provides a dynamic uniform draught fan cover plate component for a household electrical appliance and the household electrical appliance and relates to the technical field of kitchen ware systems. The dynamic uniform draught fan cover plate component for the household electrical appliance comprises a cover plate base, dynamic air-out grids and fixed air-feeding grids. The cover platebase is used for being connected with the cavity wall of the household electrical appliance, an air chamber is formed between the cover plate base and the cavity wall, the air chamber is used for containing fan blades of a draught fan, and the fixed air-feeding grids are fixed to the cavity wall or fixed to the cover plate base. The fixed air-feeding grids or the cover plate base is provided withan airflow channel communicating with a cavity of the household electrical appliance and the air chamber, and the dynamic air-out grids are embedded between the fixed air-feeding grids and the coverplate base and communicate with the airflow channel. The joint positions of the dynamic air-out grids and the fixed air-feeding grids are provided with a damping guide rail, and the dynamic air-out grids rotate along the damping guide rail under the external wind action. The invention further relates to the household electrical appliance which is provided with the dynamic uniform draught fan coverplate component for the household electrical appliance. By the adoption of the dynamic uniform draught fan cover plate component for the household electrical appliance, the dynamic and uniform air-out effect can be realized.

Description

technical field [0001] The invention relates to the technical field of kitchen utensil systems, in particular to a dynamic uniform fan cover assembly of a household appliance and the household appliance. Background technique [0002] At present, most of the existing built-in electric ovens in China, as well as household appliances with heating and drying functions such as microwave ovens, disinfection cabinets, and dishwashers, mostly use the air outlet method of the rear fan. In the wind mode, the air is mainly relied on the openings on the cover assembly. However, there are two shortcomings in the existing cover assembly: first, the air outlet hole of the cover assembly can take into account all positions of the oven liner. Second, it is more difficult to achieve uniform air distribution in all modes taking into account all modes; the above two shortcomings will directly lead to poor cooking effects for end users. [0003] In view of this, there is an urgent need for a co...
