Embodiment Construction

[0038] Next, specific embodiments of the air conditioner of the present invention will be described with reference to the drawings.

[0039] figure 1 It is an overall configuration diagram showing Embodiment 1 of the air conditioner of the present invention.

[0040] The air conditioner 1 is composed of an outdoor unit 10, an indoor unit 20 connected to the outdoor unit 10 by refrigerant piping, and the like. In addition, the indoor unit 20 is connected to a remote control switch (remote control switch) 40 via an operating state communication unit 30 .

[0041] Above-mentioned indoor unit 20 is provided with human sensor 21, and this human sensor 21 can perceive the activity of people, to grasp the activity of the people in the room where this indoor unit 20 is installed, that is to grasp the state of the room. The detection information of 21 is sent to the operation state determination unit 22 provided in the indoor unit 20 . The operating state judging unit 22 judges whet...

Abstract

The present invention relates to an air conditioner with a higher energy saving effect, through which an operation state can be easily determined, wherein the air conditioner (1) is provided with an outdoor machine (10), an indoor machine (20) and a remote control switch (40). The air conditioner is also provided with a human sensor (21) for detecting the motion of humans in a room, an operation state determination unit (22) connected with the human sensor, an operation motion control unit (24) for controlling the operation motion of the air conditioner, and a timing unit (23). When the operation state determination unit determines the motion of humans to be small according to the detection information of the human sensor, the operation capacity of the air conditioner is reduced; further, the motion of humans is determined to be small according to the detection information of the human sensor in a certain time, the operation capacity of the air conditioner can be further reduced; and it is determined that no human motions, after the timing unit operates for a certain time, the air conditioner stops operation. It is displayed on the operation state display unit (25, 43), etc., that that air conditioner stops operation according to the detection information of the human sensor.

Description

technical field [0001] The present invention relates to an air conditioner, and more particularly to an air conditioner performing energy-saving operation. Background technique [0002] The start / stop operation of the air conditioner is performed by a remote switch provided in an air-conditioned area where the air conditioner performs air conditioning, or a remote control device provided in a remote place. The remote control switch provided in the air-conditioning area operates according to the user's wishes in the air-conditioning area and displays information related to the operating state, thereby providing an advantage that the user can fundamentally manage and grasp the operation of the air conditioner. In addition, the operation control of the air conditioner may be performed by a human detection sensor that detects a human being. [0003] For example, there is an example described in Patent Document 1 (Japanese Unexamined Patent Application Publication No. 2006-16212...
