Abstract

PURPOSE:To ensure the operation of a fan rapidly by incorporating a sensing means into a transmitter for wireless remote operation so that signals from the sensing means etc., are transmitted to the side of a main body over wires when a transmitter is fixed to the main body of an air cleaner. CONSTITUTION:A sensing means 22 for detecting a moving object or detecting contamination of air is provided so that a fan is actuated when signals from the means 22 are received and said signals have reached predetermined levels. The means 22 is incorporated into a transmitter 61 for wireless remote operation, whereby the transmitter 61 is detachably fixed to an air cleaner main body 1 which receives the signals delivered from the transmitter 61. And when the transmitter 61 is fixed to the main body 1, electric connections of the sensing means 22 etc., with the transmitter 61 and the main body 1 are provided by means of wire connections. As a result, detections by means of the sensing means can be conducted rapidly and surely. Further, when the means 22 is mounted to the main body 1, signals are sent from the means 22 by means of a wire system, enabling thereby restrictions in remote control to be released.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention detects the movement of house dust, cigarette smoke, human bodies, etc. in the indoor air and removes them by driving a fan. It also relates to air purifiers that remove bad odors that occur indoors. [Conventional technology 1] Conventionally, in this type of air purifier, a sensor that detects moving objects or air pollution is built into the air purifier itself, and the fan is driven by the output of the sensor. Autonomous driving is common. [Problems to be Solved by the Invention] However, when the sensor is built into the air purifier body, the dirt detection sensor does not detect dirt near the sensor even if the dirt concentration reaches the standard value in some parts of the room. The fan will not be activated unless the dirt concentration exceeds the standard value. Furthermore, a sensor for detecting a moving object does not drive a fan unless a human body or the like moves within its detection range. In other words, there is a problem in that blind spots may occur depending on the environment in which the device is used.

In addition, if the sensor is removable from the air purifier body, so-called wireless remote controllers generally use an infrared type, and the transmission and reception method is a narrow range with a limited transmitting angle and receiving angle. There has been a problem in that it is difficult to satisfy the above constraints when incorporating the device into the main body.

The present invention has been provided in view of the above-mentioned points, and depending on the usage environment, for example, in the case of a sensor for detecting dirt, it may be placed near an ashtray where dirt is likely to occur, or it may be used for detecting moving objects. The sensor can be installed near entrances and exits where there is a lot of human body movement, allowing for quick and reliable detection by the sensing means.Furthermore, when the sensing means is attached to the main body of the air purifier, it can be connected to the sensing means using a wired method. The purpose of this project is to provide an air purifier that sends signals to eliminate the limitations of using a remote control. [Means for Solving the Problems] The present invention includes a sensing means housed in a transmitter for wireless remote operation, and the transmitter is attached to and detached from an air purifier body that receives signals sent from the transmitter. The transmitter can be attached freely, and when the transmitter is attached to the air purifier body, the electrical connection of the sensing means and the like between the transmitter and the air purifier body is a wired connection.

[Function] With the above configuration, when the transmitter containing the sensing means is removed from the air purifier body, the transmitter can be installed at any location, and the transmitter can be installed in the air purifier body. When installed, signals from the sensing means etc. are transmitted to the air purifier main body side by wire.
