Abstract

PROBLEM TO BE SOLVED: To provide an air conditioner with a sound sensor achieving power saving while considering amenity.SOLUTION: The air conditioner includes: a sound sensor; a communication hole communicating the sound sensor and an indoor space, the hole positioned inside the ends of blowing ports along the axial direction of a cross-flow fan and between the lowermost end of an upper wall of a blowing air passage and a suction port; a filter positioned at the suction port; and an automatic cleaning device cleaning the filter. Thus, the obtained air conditioner with a sound sensor can save power while considering amenity.

Description

technical field [0001] The present invention relates to an air conditioner equipped with an acoustic sensor for detecting indoor sound. Background technique [0002] Air conditioners condition indoor air by circulating indoor air to a heat exchanger, conditioning the air by heating, cooling, dehumidifying functions, etc., and then blowing the adjusted air into the room. In recent years, from the viewpoint of preventing global warming, more energy-saving operation of air conditioners has been strongly demanded. With recent advances in sensor technology, various air conditioners equipped with sensors have appeared. As one of them, various air conditioners have been proposed. Installing an acoustic sensor in an air conditioner improves operability and enables energy-saving operation with comfort in mind. Patent Documents 1 to 5 are known as such conventional techniques. [0003] Patent Document 1 describes a control device for an air conditioner. The indoor equipment of the a...
