Air guide device and air conditioner indoor unit

Abstract

The invention provides an air guide device and an air conditioner indoor unit. The air guide device is used for being arranged in a shell of the air conditioner indoor unit and comprises an air guide barrel, an air duct is limited to guide air flow in the shell to an air supply outlet of the shell, and the inner wall, close to an air outlet, of the air duct is in a gradually-shrinking shape enabling the overflowing section to be gradually reduced in the air flow direction; the flow guide part is arranged in the air duct, an annular air outlet gap is defined by the flow guide part and the inner wall of the air duct, and the flow guide part is used for guiding the airflow to the annular air outlet gap so that the airflow can be gradually blown to the air supply outlet in the center direction of the airflow in a gathering mode under the guidance of the gradually-shrunk inner wall of the air duct; the gradually-shrunk inner wall of the air channel is composed of a plurality of movable cylinder wall plates arranged in the circumferential direction of the air guide cylinder, and each cylinder wall plate is configured to be capable of adjusting the distance between the cylinder wall plate and the flow guide piece by changing the position of the cylinder wall plate, so that the air outlet amount of the annular air outlet gap on the cylinder wall plate is changed. According to the air guide device, the air conditioner indoor unit has better long-distance air supply and powerful air supply effects.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air guide device and an air conditioner indoor unit. Background technique [0002] Existing air-conditioning indoor units all blow cold wind or hot wind indoors through the air supply port to realize the cooling or heating function. The size of the air supply distance of the indoor unit has a great influence on the cooling / heating speed and the uniformity of the indoor space temperature. The control of the air supply angle plays an important role in avoiding the cold / hot air from the human body. [0003] However, most air-conditioning indoor units in the prior art increase the air supply distance by increasing the fan speed, and change the wind direction through air guide devices such as air guide plates or swing leaves, and the structure lacks innovation. Moreover, the increase in fan speed will lead to a series of problems such as increased air conditioning power a...

Problems solved by technology

[0003] However, most air-conditioning indoor units in the prior art increase the air supply distance by increasing the fan speed, and change the wind direction through air guide devices such as air deflectors or swing leaves, and the structure lacks innovation.

Moreover, the increase in fan speed will lead to a series of problems such as increased air conditioning power and increased noise, which will affect user experience.
