Description

Air guide ring structure, air conditioner internal machine and cooking utensils

Technical field

The invention relates to the technical field of air conditioners, in particular to an air guiding ring structure for an internal machine of an embedded air conditioner, an embedded air conditioner internal machine and an air conditioner.

Background technique

In the prior art, the inner air guiding structure of the embedded air conditioner has a wire terminal and a wire slot because the electric device wire body such as the water pump wire and the water level switch wire needs to be wound. Such a card line device increases the burden on the production line workers and requires a card line. In particular, when the safety specifications are more and more strict, some line bodies need to be more than 1 mm thick, and the softness of the line body is greatly reduced, resulting in difficulty in the card line. In addition, the wire body is exposed on the air guiding ring, which is not in line with the aesthetics and does not meet the safety requirements.

At the same time, the air inlet surface of the inner air guiding ring of the existing embedded air conditioner is a curved surface, and the centrifugal wind wheel diversion ring is also a curved surface, and a certain gap is reserved between the back side of the air guiding surface of the air guiding ring and the centrifugal wind wheel guiding ring. The height of the section along the air inlet direction of the air guide ring exhibits an irregular change. When the gap is small, the airflow speed changes greatly, and it is easy to generate large noise. When the gap is large, the backflow phenomenon at the air guide ring is serious, and the air volume loss will be larger, which causes the air volume to decrease, which reduces the user's satisfaction with the product; When the gap exhibits an unset change along the air inlet direction of the air guide ring, such as multiple undulations, the system may generate additional aerodynamic noise.
