Problems solved by technology

[0004] This structure only reduces the noise generated by the airflow impinging on the heat exchanger. If you want to increase the air volume, you still need to increase the fan speed, but it does not reduce the noise of the fan itself when you need to increase the air volume and increase the fan speed. Noise suppression is not good enough

Abstract

The invention discloses an air outlet structure of an air conditioner indoor unit. The air outlet structure comprises a housing case main body; an air conditioner air inlet and an air conditioner air outlet are respectively arranged at two ends of the housing case main body; a heat exchanger and centrifugal fans are arranged in sequence between the air conditioner air inlet and the air conditioner air outlet; an annular air flue is arranged at the air conditioner air outlet; an air outlet is arranged on the annular air flue; the quantity of the centrifugal fans is at least two; the centrifugal fans are arranged in the housing case main body, wherein an air outlet of at least one centrifugal fan is communicated with the annular air flue through an induced draft passage; and the air outlet of the at least one centrifugal fan is opposite to the air conditioner air outlet. At least two centrifugal fans are arranged; through accelerating the air outlet speed of one of the centrifugal fans, the air speed of the other centrifugal fan is driven; the air quantity is guaranteed while the air speed is increased; air force is natural; outlet air is uniform; and the air outlet structure is energy-saving and environment-friendly, is electricity-saving, and is small in noise and simple in structure.

Description

technical field [0001] The invention relates to an air conditioner indoor unit, in particular to an air outlet structure of the air conditioner inner unit. Background technique [0002] In recent years, with the improvement of living standards, air conditioners have been popularized in daily life. At the same time, consumers' requirements for air conditioner performance have gradually increased. While providing comfortable air, high air volume and low noise, energy saving and environmental protection have always been people's pursuit of goals. [0003] Chinese patent document CN202403388U discloses a ducted air conditioner including an indoor unit and an outdoor unit. Located in the air intake section of the air supply device. According to the ducted air conditioner of the present invention, the heat exchanger is arranged on the air inlet side of the air supply device, so as to prevent the high-speed air flow from directly impacting the heat exchanger when the air volume i...
