Air guide device, air conditioner and control method for air conditioner

Abstract

The invention discloses an air guide device which is arranged at an air outlet of an air conditioner. The air guide device comprises a plurality of air outlet parts which form a sealed polyhedral structure, wherein the air inlet surface of at least one air outlet part among the plurality of air outlet parts is connected to the air outlet; air flow blown out by an indoor fan of the air conditioner is respectively exhausted from the air outlet through air outlet surfaces of the plurality of the air outlet parts. The invention further discloses the air conditioner and the control method for the air conditioner. According to the scheme, air blown out by the indoor fan can be decomposed and dispersed to different air outlet surfaces to realize air-out; in case of not changing air outlet amount, air-outlet air speed can be reduced because of an increased air outlet area, so that an allowable air speed range of a human body comfortable area is controlled by controlling the air outlet area, and therefore, the low-blowing-feeling requirements are realized.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air guiding device, an air conditioner and a control method for the air conditioner. Background technique [0002] In order to ensure the cooling effect of the air conditioner, the air conditioners currently on the market often design a larger air outlet and the wind speed of the air outlet. The wind speed of the air outlet of the general product is 5-6m / s within a certain distance; Because of the air conditioner itself, the temperature of the air outlet is generally 10-15°C. It is conceivable that such low-temperature and high-speed airflow blows on the human body not only does not have comfort, but also easily causes the sweat glands of the human body to close due to the "cold wind" blowing directly on the human body. Affecting normal metabolism and secretion, staying in an air-conditioned room for a long time and blowing "cold wind" is very prone to "air-conditioni...

[0002] In order to ensure the cooling effect of the air conditioner, the air conditioners currently on the market often design a larger air outlet and the wind speed of the air outlet. The wind speed of the air outlet of the general product is 5-6m / s within a certain distance; Because of the air conditioner itself, the temperature of the air outlet is generally 10-15°C. It is conceivable that such low-temperature and high-speed airflow blows on the human body not only does not have comfort, but also easily causes the sweat glands of the human body to close due to the "cold wind" blowing directly on the human body. Affects normal metabolism and secretion, staying in an air-conditioned room for a long time and blowing "cold wind" is very prone to "air-conditioning disease"

Traditional air-conditioning indoor units often use conventional air deflectors. Due to the large air outlets of this type of air deflectors, when the room temperature has reached a comfortable temperature and the heat exchange rate does not change much, the wind speed at the air outlet cannot be reduced. , to meet the requirements of low wind feeling
