Abstract

The invention provides an air conditioner indoor unit and a volute thereof. The volute comprises a front wall plate (1), a tongue (2), a straight tongue side plate (21) and an arc tongue side plate (22); the straight tongue side plate (21) is connected to one end of the tongue (2); the arc tongue side plate (22) is connected to the other end of the tongue (2). The straight tongue side plate (21) is provided with first silencing holes (3); a first silencing cavity (31) communicated with the first silencing hole (3) is arranged outside the straight tongue side plate (21); the arc tongue side plate (22) is provided with second silencing holes (4); a second silencing cavity (41) communicated with the second silencing hole (4) is arranged outside the arc tongue side plate (22); the tongue (2) is provided with third silencing holes (5); a third silencing cavity (51) communicated with the third silencing holes (5) is arranged outside the tongue (2). The volute has the advantages that a peak value of low fan rotational noise is effectively reduced and volute noise is effectively reduced accordingly.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, and more specifically, to an air conditioner indoor unit and a volute case thereof. Background technique [0002] As people's demand for air conditioners continues to increase, the demand for noise reduction of air conditioners also increases. [0003] In the indoor unit of the air conditioner, the main component that generates noise is the air duct system, and the volute generates the most noise in the air duct system. The fan achieves uniform air supply through the action of the volute, which makes the air supplied by the fan come into contact with the volute to generate noise. Under the premise that the power of the air conditioner is constantly increasing, the air supply volume also increases, and the noise generated by the volute also increases, which seriously affects the comfort of the user. [0004] To sum up, how to provide a volute to reduce noise is an urgent problem ...
