Air conditioner indoor unit

Abstract

The invention discloses an air conditioner indoor unit. The air conditioner indoor unit comprises a surface frame with an air outlet, an air deflector which is movably connected to the surface frame and covers the position of the air outlet, a control panel which is arranged in the surface frame, a step motor which is electrically connected to the control panel, and a turbulent flow plate which is fixedly connected to the step motor, wherein the turbulent flow plate is fixed to the surface frame, and covers the position of the air outlet; the turbulent flow plate is provided with spray holes which are adjustable in hole diameter size in a rotary mode under the drive action of the step motor, and are distributed unevenly so as to regulate velocity of airflow which flows through the air outlet. According to the air conditioner indoor unit, air speed is precisely controlled and reduced step by step by combining the spray holes with different diameters in the turbulent flow plate, so that the indoor air temperature is controlled, and therefore, refrigerating and heating comfort of the air conditioner are improved, and the 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. 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 temperature, the air speed can be increased appropriate...

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.
