Abstract

The invention provides a fan structure, a fresh air device and an indoor unit of an air conditioner. The fan structure comprises a volute assembly and blades, wherein the volute assembly is provided with a first air inlet and a first air outlet; the blades are disposed in the volute assembly, and are used for sucking gas into the volute assembly from the first air inlet and discharging the gas through the first air outlet; the shell of the volute assembly is provided with a plurality of air outlet holes, so that part of the gas in the volute assembly flows out through the plurality of air outlet holes. The fan structure of the present invention solves the problems of excessive noise and small air output in the fan structure of the prior art.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a fan structure, a fresh air device and an air conditioner indoor unit. Background technique [0002] Existing air conditioners perform heat exchange in a confined space, and the continuous circulation of indoor air can easily lead to a decrease in indoor air quality, resulting in poor user experience. In this regard, more and more air conditioners are equipped with fresh air replacement devices. [0003] However, due to structural space constraints and pipe routing restrictions, the fresh air device added to the indoor unit of the air conditioner often has the problems of excessive noise and low fresh air volume, and the user experience is generally poor. [0004] Moreover, the pressure relief port of the pressure relief volute tongue for noise reduction in the prior art is a closed space, which will cause air volume loss. Contents of the invention [0005] The main purpos...
