Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an air cleaner used as an air cleaner and incorporated in a room air conditioner or the like, and more particularly to a remote control type air cleaner.

[0002]

[Prior Art]

 In a remote-controlled air purifier, the main body of the cleaning device is usually operated by the wireless remote controller, and the degree of dirt in the air is detected by the dirt sensor inside the main body, and the cleaning is performed at the fan speed according to the degree of dirt The device body is driven.

[0003]

[Problems to be solved by the device]

 However, since a dirt sensor that detects dirt in the indoor air is provided on the side of the cleaning device body and is away from the person who operates the wireless remote controller, the degree of contamination of the air around the person and the operating status of the cleaning device body It was unavoidable that there was some gap between the two. For example, if only the people around the room are locally contaminated by cigarette smoke, etc., the cleaning device itself cannot be operated at a fan speed corresponding to the contamination.

The present invention has been made in view of the above circumstances, and an object thereof is to provide an air cleaning device that can always perform an operation according to the degree of contamination of the air around a person who enjoys the air cleaning function. And

[0005]

[Means for Solving the Problems]

 The air cleaning apparatus according to the present invention is an air cleaning apparatus comprising a cleaning apparatus main body for cleaning air discharged by a fan by a filter and discharging the air, and a wireless remote controller for transmitting an operation signal to the cleaning apparatus main body by remote control. It is characterized in that a dirt sensor is mounted on the remote controller, and the dirt condition of the air detected by the dirt sensor or the operation information according to the dirt condition is transmitted to the cleaning apparatus main body.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic diagram showing the schematic configuration of an example of an air cleaning device embodying the present invention, FIG. 2 is a schematic diagram showing the operating principle of a dirt sensor provided in a wireless remote controller, and FIG. 3 is a circuit of a wireless remote controller. FIG. 4 is a block diagram schematically showing the configuration, and FIG. 4 is a table showing an operation pattern of the cleaning apparatus main body.

The air cleaning device shown here is an electrostatic air cleaning device, and is composed of a cleaning device body 10 and a wireless remote controller 20. The cleaning apparatus main body 10 includes a fan 11, a positive electrode 12, a negative electrode 13, and a removable electrostatic filter 14. The fan 11 is operated based on the operation information received by the remote control receiver 15. The air sucked into the cleaning device main body 10 by the fan 11 becomes clean air because dirt particles therein are charged to a positive potential and are adsorbed by the electrostatic filter 14 charged to a negative potential. Is ejected.

The wireless remote controller 20 of the air purifier includes a start / stop key 21, a dirt sensor 22, a display device 23, and a remote control transmission device 24. The dirt sensor 22 detects the degree of dirt of the air flowing into the case through the slit 25 provided in the case of the wireless remote controller 20. The display device 23 is composed of a plurality of LEDs and displays the degree of contamination of the air detected by the contamination sensor 22.

As shown in FIG. 2, the dirt sensor 22 mounted on the wireless remote controller 20 has an infrared LED 22a and a light receiving diode 22b. When the air flowing into the case 22c of the dirt sensor 22 is clean, the infrared light emitted from the infrared LED 22a is not received by the light receiving diode 22b. When dirty air flows into the case 22c, the dirt particles in the air diffusely reflect infrared rays and the infrared rays are received by the light receiving diode 22b. Therefore, a signal corresponding to the degree of contamination of air is output from the light receiving diode 22b.

The signal output from the light receiving diode 22b of the dirt sensor 22 is amplified by the amplifier 26 and input to the microcomputer 27, as shown in FIG. The micro computer 27 displays the dirt level on the display device 23 based on the information about the dirt level of the air input from the light receiving diode 22b, and calculates the fan speed according to the dirt level (see FIG. 4). The calculated fan speed is transmitted from the remote control transmitter 24.

In the above air purifier, when the operation / stop key 21 of the wireless remote controller 20 is operated to start the operation, the dirt sensor 22 detects the dirt level of the air. Then, the detected dirt level is displayed on the display device 23, and information about the fan speed corresponding to the dirt level is transmitted from the remote control transmission device 24. The cleaning device main body 10 receives the information about the fan speed with the remote control receiving device 15 and starts rotating the fan 11.

At this time, since the wireless remote controller 20 is in the hand of the person who operates the wireless remote controller 20, the fan 11 starts rotating at a fan speed corresponding to the degree of contamination of the air around the person who operates the wireless remote controller 20. It Even after the operation is started, the dirt sensor 22 continues to detect the dirt level, and if the dirt level decreases, the fan speed decrease information is transmitted, and conversely, the fan speed increase information is transmitted. In this way, accurate air cleaning that is not affected by the conditions around the cleaning device body 10 is performed. Further, a person who operates the wireless remote controller 20 can accurately know how dirty the surrounding air is by the display device 23.

In the above embodiment, the fan speed corresponding to the degree of air pollution is mainly transmitted by remote control. However, in addition to the fan speed, intermittent operation of the fan, movement of the wind direction louver, etc. are transmitted by remote control. can do. In addition, it is possible to transmit the degree of air pollution by remote control and calculate operating information such as fan speed in the cleaning device body.

[0014]

[Effect of the device]

 As described above, in the case of the air cleaning device according to the present invention, the dirt sensor for detecting the dirt of the air is provided on the side of the wireless remote controller, and the dirt of the air around the person operating the wireless remote controller is Accurately reflected in driving conditions. Therefore, the cleaning device itself always operates according to the air pollution around the person in the room. Therefore, the person in the room can always enjoy the functions of the air cleaning device to the maximum.
