Air conditioner indoor unit and control method of air conditioner

Abstract

The invention discloses an air conditioner indoor unit. The air conditioner indoor unit comprises a surface frame with an air outlet, an air guiding plate movably connected to the surface frame and covering the air outlet, a control plate arranged inside the surface frame, a step motor electrically connected with the control plate, and a first turbulent plate and a second turbulent plate which are fixedly connected with the step motor, wherein the first turbulent plate and the second turbulent plate are further rotationally connected onto the surface frame; the step motor rotates the first turbulent plate or the second turbulent plate to the air outlet so as to cover the air outlet under the control of the control plate; first spray holes are formed in the first turbulent plate and second spray holes with diameters and sizes different from those of the first spray holes are formed in the second turbulent plate so as to adjust airflow speed at the air outlet. The invention further discloses a control method of an air conditioner. According to the technical scheme provided by the invention, the air speed can be gradually controlled and reduced through the spray holes with different diameters in different turbulent plates, so that cooling and heating comfort of the air conditioner is improved and thus a user experience is improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to an indoor unit of an air conditioner and a control method for the air conditioner. Background technique [0002] In the American industry standard ASHRAE55-2010, it is clearly stated that within the air velocity range allowed by the human comfort zone, when the air temperature is greater than or equal to 25.5°C, the upper limit of the air velocity is 0.8m / s; when the air temperature is less than or equal to 22.5°C , the upper limit of the air velocity is 0.15m / s, that is, the air velocity that meets the thermal comfort of the human body can be appropriately increased with the increase of the air temperature. When the air conditioner is in the initial cooling process and finally reaches a steady state, the wind speed required to meet the comfort of the human body is different. During the cooling process, since the actual temperature is higher than the comfortable temperatur...

AI Technical Summary

Problems solved by technology

[0003] At present, the air conditioners on the market usually have a relatively large air outlet and the wind speed of the air outlet, and the wind speed at a certain distance from the air outlet is 5-6m / s. When the air conditioner is cooling, the temperature of the air outlet is generally 10-15°C. In this way, the low-temperature and high-speed airflow blowing on the human body is not only poor in comfort, but may also cause air-conditioning problems in the user, thereby affecting the health of the user.
