Abstract

(57) [Summary] [Purpose] A human sensor can detect the direction in which a person is present. Further, the blowing direction of the wind can be automatically controlled so that it does not hit the person, and if the person is only far away, the air volume is increased to improve the reactivity of the cigarette sensor. [Structure] The position of the motion sensor 14 is automatically changed by a motion sensor position control motor 30 to determine in which direction a person is, and when the motion sensor 14 detects the presence of a person, The louver is controlled by the louver control motor 27 so that the wind does not flow in the detected direction, and the fan motor 17 is controlled so as to increase the air volume when a person is only in a distant place.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an air cleaner equipped with a human sensor.

[0002]

[Prior Art]

 In a conventional air purifier equipped with a motion sensor, a dome-shaped multi-lens is installed in front of the motion sensor to detect the presence or absence of a person over a wide area at a fixed, fixed position. For example, the power of the air purifier was automatically turned on, and the power was turned off when there was no one. In addition, although the dome-shaped multi-lens expands the range that can detect the presence of people, it cannot detect every corner of the room.

In the vicinity of the outlet of the air purifier, the wind directly hits a person and causes discomfort. Therefore, a louver that changes the direction of the wind is provided, but the direction of the louver must be changed manually. did not become.

Further, in an air purifier equipped with a cigarette sensor, the sensitivity of the cigarette sensor is generally poor, and therefore, when smoking a cigarette at a distance from the air purifier, the cigarette sensor is not sensitive, and therefore the air volume is reduced. It did not switch from weak to strong, and the air cleaning effect was not fully obtained.

[0005]

[Problems to be solved by the device]

 A first object of the present invention is to extend the detection area of a motion sensor and detect the direction in which a person is present.

A second object of the present invention is to enable the wind direction of the louver to be automatically controlled in a direction or range that does not hit a person.

A third object of the present invention is to increase the air volume and improve the reactivity of the tobacco sensor only when a person is far away.

[0008]

[Means for Solving the Problems]

 In order to achieve the first object, the present invention provides an air purifier equipped with an ionization part, a dust collection part, a high pressure generation part, a louver that changes the blowing direction of the wind, and a motion sensor, and the position or orientation of the motion sensor. A sensor displacement means for automatically changing the angle in at least one of the vertical direction and the horizontal direction is provided.

In order to achieve the second object, there is provided louver control means for automatically controlling the orientation of the louver based on a detection signal from a human sensor.

In order to achieve the third object, an air volume control means for automatically controlling the air volume according to a detection signal from a human sensor is provided.

[0011]

[Action]

 According to the present invention, by automatically changing the position or the directivity angle of the motion sensor, the detection area of the motion sensor can be expanded and the direction of the person can be confirmed. Also, when the presence sensor detects the presence of a person, the louver is controlled so that the wind does not flow in the detected direction, or the amount of air is increased when the person is only at a distance. The air volume can be adjusted automatically.

[0012]

【Example】

 Next, an embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIGS. 1 and 2, the air purifier of this example has a suction port 11 on an upper surface of a housing 10 and a blowout port 12 at a lower portion thereof. It can be changed. On the outside of the housing 10, a human sensor 14 that detects infrared rays emitted from a person and detects the presence or absence of the person is mounted so as to be vertically and horizontally displaceable.

As shown in FIG. 3, an ionization unit 15, a dust collection unit 16, and a fan motor 17 are sequentially arranged in the housing 10 from the suction port 11 side toward the blow port 12 side, and air containing dust is disposed. The air is sucked into the housing 10 from the suction port 11 by the air blown by the fan motor 17, is collected in the housing 10 as clean air, and is blown out from the blowout port 12.

As shown in FIG. 4, the ionization unit 15 makes a dust collecting electrode plate 19 face each of a plurality of ionization wires 18, and the dust collecting unit 16 has a plurality of positive electrodes as shown in FIG. A plate 20 and a plurality of ground electrode plates 21 are alternately opposed to each other. Between the ionization line 18 and the dust collecting electrode plate 19 and between the positive electrode plate 20 and the ground electrode plate 21, A high voltage is applied from the high voltage generator 22 shown in FIG.

When a high voltage is applied between the ionization line 18 and the dust collection electrode plate 19, an ionization current flows from the ionization line 18 to the dust collection electrode plate 19, and dust in the air sucked into the housing 10 becomes positive. Be charged to. The charged dust flows into a high electric field formed between the positive electrode plate 20 and the ground electrode plate 21 on the downstream side, and is collected by the ground electrode plate 21 by the Coulomb force.

In FIG. 6, the high voltage generator 22 boosts the low voltage from the power source 23 and applies a high voltage of, for example, 7 KV to the ionizer 15 and a high voltage of, for example, 3 KV to the dust collector 16. The microcomputer 24 controls the motor driver 26 of the fan motor 17 and the motor driver 28 of the louver control motor 27 for automatically changing the direction of the louver 13 by the signals from the human sensor 14 and the cigarette sensor 25, and The state, for example, strong / medium / weak air volume and the direction of the louver 13 are displayed on the display unit 29. The micro computer 24 also controls the motor driver 31 of the motion sensor position control motor 30 that moves the motion sensor 14 up and down and left and right to move the motion sensor 14 up and down and left and right at fixed intervals. Change automatically (every 1 minute, for example).

Next, an example of control by the microcomputer 24 will be described. When the human sensor 14 detects a person, a signal is obtained from the human sensor 14 and the position of the human sensor 14 is constantly monitored by the microcomputer 24, so that the microcomputer 24 can determine in which direction the person is. Assuming that a person is diagonally forward left of the air purifier as shown in FIGS. 1 and 2, the micro computer 24 operates the louver control motor 27 via the motor driver 28, and the louver 13 operates. Make sure that the direction of the wind is in the center, to the right, or diagonally below, so that no one is diagonally forward to the left.

When it is determined that the person is only far away, the fan motor 17 is controlled via the motor driver 26 in order to quickly inhale the cigarette smoke. The air volume that is set to “” is automatically switched to “medium” or “strong”.

In the embodiment, the position of the human sensor 14 is changed vertically and horizontally, but the directivity angle may be changed.

[0020]

[Effect of the device]

 According to the air cleaner of the first aspect, by automatically changing the position or the directivity angle of the motion sensor, the detection area of the motion sensor can be expanded and the direction of the person can be confirmed.

According to the second aspect, when the human sensor detects the presence of a person, the louver can be controlled so that the wind does not flow in the detected direction.

According to the third aspect, when the person is only at a distant place, it is possible to guarantee the effective operation of the cigarette sensor by automatically adjusting the air volume so as to increase the air volume.
