JPH04118017A - Sensor attaching device for on-vehicle air cleaner - Google Patents

Abstract

PURPOSE:To sensitively perceive the contamination of air by allowing a holding part member of the sensor to be freely bendable, freely shrinkable and freely rotable and also a signal of the sensor to be originated from an ultrasonic transmitter. CONSTITUTION:The holding part member 5 of the sensor 4 perceiving the contamination of air is constituted of a mounting table having freely bendable, freely shrinkable supporting bar 6 and freely ratable fulcrum 7 and attached in the ceiling section of a car. By attaching the sensor 4 on to the nearest position of a driver, when the driver smokes a tobaco, the sensor 4 perceives sensitively the smoke and sends the signal to the control part of the main body and the air fun is operated to purify the contaminated air. By this means, the wiring of the sensor to the main body is eliminated and the monitoring area is expanded and accuracy and residential comfortness are improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a sensor mounting device for a vehicle-mounted air cleaner, which is used in a passenger car or the like and has a function to operate according to air pollution.

Conventional technology In recent years, air purifiers have been widely used in passenger cars and the like.

Conventionally, in this type of in-vehicle air purifier, the sensor that detects air pollution has generally been integrated into the main body and attached to the rear tray.

The configuration will be described below with reference to FIGS. 4 and 6.

As shown in the figure, the in-vehicle air purifier includes a main body 1 that houses functional parts, a blower fan 2 that sucks in dirty air, a filter 3 that filters dust contained in the air by passing the air through it, and a It consists of a sensor 4 that detects dirt, and the sensor 4 is integrated into the front of the main body 1 and attached to the rear tray of a passenger car. It was also attempted to separate the sensor 4 from the main body 1, but this was not realized because there was no suitable mounting device for the sensor 4.

Problems to be Solved by the Invention In such a conventional air purifier for use in passenger cars, etc., the sensor 4 that detects air pollution is integrated into the front of the main body 1 and installed in the six-tray tray of the passenger car. Since the sensor was attached to the sensor 4, it was located far away from the driver's seat, which caused the problem that it took time for dirty air to reach the sensor 4 and the response speed was slow.

The present invention solves the above problems, and aims to provide a sensor mounting device for a vehicle-mounted air cleaner that can sensitively detect air leakage.

Means for Solving the Problems In order to achieve the above object, the first means for solving the problems of the sensor mounting device for a vehicle air cleaner of the present invention is to make the holding member of the sensor bendable, telescopic or rotatable. ,
In addition, the third means of solving the problem is that the sensor signal is generated by an ultrasonic transmitter, and the main body is equipped with a receiving device, and the sensor is installed at a position opposite to the receiving device of the main body. .

Function The first means for solving the problem described above has the effect that by making the sensor holding member bendable, telescopic, or rotatable, the sensor can be mounted at a position closest to the driver; The function of the second problem solving means is to transmit the sensor signal to an ultrasonic transmitting device, and the main body is equipped with the receiving device, and the sensor is installed at a position opposite to the receiving device of the main body. Since we have set up
There is no need for wiring between the sensor and the main body, and the installation area can be expanded.

EXAMPLES Hereinafter, examples of the present invention will be described with reference to the drawings. In this embodiment, the same components described above are given the same reference numerals, and their explanations will be omitted.

The characteristic structure of this embodiment is in the sensor mounting part of the vehicle air cleaner. FIG. 1 and FIG. 2 show an embodiment of the means for solving the first problem of the present invention. That is, the holding member 5 of the sensor 4 that detects air pollution is comprised of a bendable and extendable support rod 6 and a mounting base 8 having a rotatable fulcrum 7, and is mounted on the ceiling of the vehicle.

In the above configuration, when the passenger smokes, the sensor 4 is installed at the position closest to the passenger, so that the sensor 4 sensitively detects smoke and sends a signal to the control section (not shown) of the main body, and sends a signal to the blower fan. 2 is operated to purify the dirty air.

FIG. 3 shows an embodiment related to the means for solving the second problem of the present invention.

That is, the signal from the sensor 9 that detects dirt in the air is transmitted by an ultrasonic transmitter 11, and the receiver 10 is provided in the main body, and the sensor 9 is installed at a position opposite to the receiver in the main body. Since we have set up
There is no need for wiring between the sensor 9 and the main body, and the mounting area can be expanded.

Effects of the Invention As is clear from the above description of the embodiments, according to the present invention, in a car-mounted air purifier in which a sensor for detecting air pollution is provided separately from the main body, the holding member for the sensor is bent. The sensor, which is flexible, telescopic, or rotatable, sensitively detects smoke and sends a signal to the control section of the main unit.The sensor signal is also generated by an ultrasonic transmitter, and the main unit has a receiving device, and the sensor The mounting position is opposite to the mounting position of the receiver on the main body, which eliminates the need for wiring between the sensor and the main body, expands the mounting area by one line, and improves detection accuracy and comfort. We can provide sensor mounting devices for air purifiers.
