Energy-saving control method and method for air conditioner as well as air conditioner

Abstract

The invention provides an energy-saving control method and device for an air conditioner as well as the air conditioner, wherein at least two pyroelectric sensors are arranged on the air conditioner. The energy-saving control method comprises the following steps of: detecting whether a room in which the air conditioner is located has a human body signal or not through the at least two pyroelectric sensors; when the at least two pyroelectric sensors detect that the room does not have the human body signal, counting lasting time for keeping the room to be free of people; judging whether the lasting time is greater than or equal to first preset time or not; and when the lasting time is judged to be greater than or equal to the first preset time, controlling the air conditioner to switch to an energy-saving operation state from a current operation state according to an existing working mode of the air conditioner. According to the technical scheme adopted by the invention, the energy-saving control method provided by the invention can effectively realize automatic and intelligent regulation on energy saving of the air conditioner, so that use comfort of the air conditioner is improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an energy-saving control method for an air conditioner, an energy-saving control device for an air conditioner, and an air conditioner. Background technique [0002] According to statistics, the power consumption of air conditioners accounts for more than 30% of the total power consumption in society. At present, although inverter air conditioners are more energy-efficient than ordinary fixed-speed air conditioners, they still rely on manual operations by users to control the power on and off and temperature setting. [0003] And when the user leaves the room or forgets to turn off the air conditioner when going out, the air conditioner will still operate according to the user's setting, thereby causing a waste of electric energy. [0004] The air conditioner disclosed in the related art can detect the condition of the human body according to the infrared sensor, an...

AI Technical Summary

Problems solved by technology

At present, although inverter air conditioners are more energy-efficient than ordinary fixed-speed air conditioners, they still rely on manual operations by users to control the power on and off, temperature setting, etc.

[0003] And when the user leaves the room or forgets to turn off the air conditioner when going out, the air conditioner will still run according to the user's settings, resulting in a waste of electric energy

[0004] The air conditioner disclosed in the related art can detect the condition of the human body according to the infrared sensor, and then control the working status of the air guide door, blades, fans, etc. of the air conditioner according to the detection result, so as to realize the air outlet force and air outlet angle of the indoor unit of the air conditioner. However, the switch and temperature setting of the air conditioner still need to be completed manually by the user, which brings inconvenience to the user and is not conducive to the user experience.
