no. 1 approach

[0079] figure 1 It is a front view of the indoor unit, the outdoor unit, and the remote controller of the air conditioner of this embodiment.

[0080] Such as figure 1 As shown, the air conditioner A includes an indoor unit 100, an outdoor unit 200, and a remote controller Re. The indoor unit 100 and the outdoor unit 200 are connected by refrigerant piping (not shown), and air-conditions the room in which the indoor unit 100 is installed by a known refrigerant circulation. In addition, the indoor unit 100 and the outdoor unit 200 exchange information with each other via a communication cable (not shown).

[0081] The user operates the remote control Re to transmit an infrared signal to the remote control transceiver unit Q of the indoor unit 100 . The contents of the infrared signal include instructions such as operation request, change of set temperature, timer, change of operation mode, and stop request. The air conditioner A performs air-conditioning operations such as ...

no. 2 approach

[0248] Figure 13 It is a flowchart showing air-conditioning operation control processing at the time of setting a predetermined operation mode in the second embodiment.

[0249] The air conditioner A starts the air conditioning operation control process when a predetermined operation mode is set by the remote controller Re.

[0250] In step S30 , the control unit 130 outputs a turn-on command to the near-infrared projector 141 to turn on irradiation of near-infrared rays.

[0251] In step S31 , the control unit 130 photographs the air-conditioned room through the photographing unit 121 .

[0252] In step S32 , the control unit 130 uses the object detection unit 133 to detect the presence or absence of an object and the region on the image from the image captured when the near-infrared rays are irradiated.

[0253] In step S33 , the control unit 130 outputs an off command to the near-infrared projector 141 to turn off the irradiation of near-infrared rays. Thereby, near-inf...

no. 3 approach

[0262] Figure 14 It is a flowchart showing the air-conditioning operation control process of the third embodiment.

[0263] The processing of steps S10 to S14 is the same as Figure 12 The processing of steps S10 to S14 shown is the same. When the processing of step S14 ends, the processing of step S50 is performed.

[0264] In step S50 , the control unit 130 determines whether a predetermined object is detected through the image detection unit 131 . Here, the intended object refers to, for example, an object or / and a human body. The control unit 130 performs the process of step S15 when the scheduled object is detected (Yes), and performs the process of step S18 when the scheduled object is not detected (No).

[0265] The processing of steps S15-S19 is the same as Figure 12 The processing of steps S15 to S19 shown is the same.

[0266] The control unit 130 irradiates near-infrared rays only when a predetermined object is detected, thereby reducing the detection freque...

Abstract

The invention provides an air conditioner and a control method thereof. The air conditioner comprising a capturing unit and a near infrared irradiation unit can detect objects and/or a human body at high precision by image processing. The air conditioners (A) comprises the capturing unit (121) for capturing an air-conditioned room, a near infrared projector (141) having a near infrared light-emitting diode irradiating near infrared rays to the air-conditioned room, a drive control unit for controlling the air conditioning operation according to the captured result of the capturing unit (121), and a control unit (130) for enabling the capturing unit (121) to capture the air-conditioned room in both conditions that the near-infrared rays are not irradiated to the air-conditioned room through the near infrared projector (141) and that the near-infrared rays are irradiated to the air-conditioned room through the near infrared projector (141).

Description

technical field [0001] The invention relates to an air conditioner and a control method for the air conditioner. Background technique [0002] In recent years, air conditioners are increasingly equipped with cameras in order to detect the conditions of people and rooms and perform air conditioning operations according to the conditions. The air conditioner uses the camera to recognize the entry and exit of people, or the number of people in the room, the place of activity, the amount of activity, and also recognize information such as the layout and the area where sunlight enters. The air conditioner compares this information with the temperature sensor, humidity sensor, or seasonal information to analyze it, and accurately controls the temperature, wind direction, or air volume, thereby performing air-conditioning operation while maintaining the comfort of indoor occupants. [0003] Air conditioners can use not only visible light images but also infrared (light) images, so...
