Abstract

The invention relates to an air inlet device and refrigeration equipment, the air inlet device comprises an impeller and an air guide mechanism, the impeller comprises a mounting disc and a plurality of blades, and the blades are connected to the mounting disc in a cyclone shape; the air guide mechanism comprises a bottom plate, an air guide ring and a plurality of supporting columns, an air inlet is formed in the air guide ring, the air guide ring and the bottom plate are connected through the supporting columns, a containing space is formed between the air guide ring and the bottom plate, and an air outlet communicated with the containing space is formed in the circumferential direction of the air guide mechanism; the impeller is located in the containing space, and an airflow gap is formed between the air guide ring and the impeller. According to the air inlet device, the air guide ring and the bottom plate which are connected through the supporting columns are arranged, so that the possibility of deformation of the air guide ring is reduced or avoided, then the situation that the width of the gap between the air guide ring and the impeller is increased is avoided, and the problem that in the prior art, the air inlet amount is lost due to deformation of the air guide ring is solved.

Description

technical field [0001] The invention belongs to the technical field of household appliances, and in particular relates to an air inlet device and a refrigeration device. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] Air-cooled refrigeration equipment distributes cold air to each compartment through air ducts. Some refrigeration equipment with complex air duct structures and large air duct resistance usually use centrifugal fans. , is thrown towards the edge of the impeller under the action of centrifugal force. [0004] Usually, a wind guide ring is provided near the air inlet to guide the airflow into the centrifugal fan. However, during use, the air guide ring is blown by the air flow and will gradually deform, and the gap between the air guide ring and the impeller is likely to increase. After the gap increases, cold air will be lost from the gap, which will ca...
