Problems solved by technology

In Patent Document 2, it is only determined by the amount of change in the sound whether the human activity is active, and the type of sound is not distinguished, so it is difficult to accurately determine whether it is a human activity
Patent Documents 3 to 5 do not disclose voice information, and therefore do not disclose the use of voice information for estimating the amount of activity.

Abstract

The invention provides an air conditioner which achieves comfortableness and meanwhile aims to save electricity. The air conditioner of the invention comprises an infrared sensor which detects the motion amount of a person indoors, a sound sensor for indoor sound detection, a setting part for setting the indoor set temperature, a controlling part for controlling the operation, and a motion amount determining part for determining the motion amount of the person indoors according to detection results from the infrared sensor and the sound sensor. A target value determined by the set temperature is changed in accordance with the determined motion amount of the person indoors which is determined by the motion amount determining part.

Description

technical field [0001] The present invention relates to energy-saving operation control of an air conditioner. Background technique [0002] The air conditioner sends the air heated, cooled, dehumidified, etc. through the heat exchanger into the room through the fan, thereby adjusting the indoor environment. In recent years, from the viewpoint of preventing global warming, there has been a strong demand for energy-saving operation of air conditioners. Therefore, the operation control of the air conditioner which performs an energy-saving operation while paying attention to comfort using various sensors is proposed. [0003] Patent Document 1 discloses: equipped with a sensor that acquires any one of air temperature, humidity, radiation temperature, air volume, wind direction, visible light, infrared light, sound, time, and calendar, it can monitor the user's intention, activity level, metabolic rate, and wear. A pattern classification device, an environment recognition dev...
