Air conditioner and control method and device thereof

Abstract

The invention discloses an air conditioner and a control method and device thereof. The air conditioner comprises an indoor unit. The indoor unit comprises a case, a plurality of swing blade sets anda plurality of driving assemblies, and the swing blade sets are sequentially arranged in the up-down direction. Each swing blade set comprises a plurality of air outlet swing blades arranged at intervals in the up-down direction. The multiple driving assemblies are matched with the multiple swing blade sets in a one-to-one corresponding mode. Each driving assembly is used for driving the multipleair outlet swing blades in the corresponding swing blade set to rotate. The method includes the following steps that when the air conditioner is started to operate in a heating mode, the multiple driving assemblies are controlled to drive the air outlet swing blades of the swing blade sets to keep the consistent angle, and timekeeping is started; whether timekeeping time reaches first preset timeor not is judged; and if yes, the angles of the air outlet swing blades of the upper and lower swing blade sets in the multiple swing blade sets are adjusted by controlling the multiple driving assemblies, so that the indoor vertical temperature difference is reduced. The phenomenon of indoor thermal stratification occurring when the air conditioner operates in the heating mode is effectively alleviated, and thus the indoor thermal comfort level is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method, an air conditioner control device and an air conditioner. Background technique [0002] With the development of science and technology and the improvement of people's living standards, people's requirements for living environment are gradually increasing. When the user turns on the cooling or heating function of the air conditioner, the purpose is to keep the indoor temperature within a comfortable range. However, when the heating mode is turned on, because the proportion of the hot air flow is small, it is easy to rise, so the hot air is difficult to reach. ground, resulting in hot head and cold feet, affecting user comfort and increasing power consumption in heating mode. [0003] In related technologies, wall-mounted air conditioners all use cross-flow fans. For wall-mounted air conditioners that use vertical single cross-flow fans,...

Problems solved by technology

However, the above method has the following disadvantages: increasing the radian of the upper and lower swing leaves will affect the appearance of the whole machine; increasing the fan speed will increase the noise, and the heating speed of the air conditioner can be improved by increasing the fan speed, but not necessarily Improve the problem of indoor temperature stratification
