Embodiment Construction

[0022] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] First, a brief description of the technical terms involved in the specific implementation:

[0024] When referring to the front or back of each structural component, the following is defined by the position of the structural component relative to the user in normal use; when describing the front or rear of multiple structural components, it is also defined as The definition of the position of a device composed of multiple structural parts relative to the user in normal use. Moreover, it should be noted that the use of front or back is only for convenience and simplification of description, and does not indicate or imply that the device or structure referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be interpreted as Limitations on...

Abstract

The invention discloses an indoor unit of an air conditioner. An air supply outlet and two air inlets are formed in a housing; an induced air port is formed between the two air inlets; a through air channel which passes through front and back is formed in the housing; one end of the through air channel communicates with the air supply outlet while the other end of the through air channel communicates with the induced air port; the through air channel comprises an induced air part and an air supply part; two air outlets are formed between the tail end, far from the induced air port, of the induced air part and the starting end, close to the induced air part, of the air supply part; fans are formed between the air outlets and the air inlets, and the separation distance of noise sources generated by operation of the two fans is ranged from 0.33lamda to 0.67lamda, wherein lamda is the transmission wavelength of a fundamental frequency noise of rotation of the fans in air, lamda is equal to v / f, v is the transmission speed of sound waves in air, f is the fundamental frequency of noise of rotation of the fans, f is equal to N / 60 *n, N is the quantity of fan blades, and n is the rotating speed of the high air shift fan. Noises from the noise sources generated by operation of the two fans are overlaid and the amplitude is weakened, so that the sound waves are counteracted to reduce the noise.

Description

Technical field [0001] The present invention belongs to the technical field of air conditioning, and specifically relates to an air conditioning indoor unit. Background technique [0002] An air conditioner that can normally blow out the heat exchange air after heat exchange by the heat exchanger and introduce external non-heat exchange air by generating negative pressure to achieve mixed air supply has been a hot topic and focus in the research and development of air conditioning technology in recent years. [0003] The applicant has applied for an air-conditioning indoor unit. The indoor unit casing is formed with an air supply port and two air inlets. An air inlet is formed between the two air inlets on the casing. On the casing or inside the casing, A through-flow duct is formed that communicates with the air supply outlet and the air induction outlet. The through-flow duct includes an air supply portion extending from the air supply outlet toward the air induction outle...
