Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an air purifier that has a function of detecting indoor air pollution using a sensor and automatically operating the air cleaner.

BACKGROUND ART The general configuration of a conventional air cleaner of this type will be described below with reference to the drawings.

4, 5, and 6, the main body 1 has an electric blower 2 built in, and the air taken in from the intake port 3 on the front passes through a prefilter 4, and is passed through a counter electrode 5 and a discharge wire 6. After being ionized and adsorbing dust by a filter 7, it is discharged from an exhaust port 8. A remote control case 9 detachably attached to the upper part of the main body 1 includes an operation switch 10 and a display section 11.
It also has a built-in gas sensor 12 to detect when the indoor air is contaminated.When the operation is set to automatic mode, the output of the gas sensor 12 is input to the detection circuit 13, which connects it to the power supply 14. The control circuit 16 connected to the operation circuit 15 makes the judgment and controls the electric blower 2, the high voltage power supply 15 that supplies voltage between the counter electrode 5 and the discharge line 6, and the display circuit 17,
It operated automatically by turning on the light when it detected dirt in the room and turning off when the room was clean. Note that 18 is a power cord.

Problems to be Solved by the Invention In such conventional air purifiers, the gas sensor 12 is built into the remote control case 9 that is detachably attached to the main body 1. There was a problem in that the sensitivity sometimes decreased because it was hidden in the shadow of 1. Furthermore, when the sensor 12 is placed in the air flowing into the intake port 3 or the air flowing out from the exhaust port 8,
There was a major problem in that the sensitivity of the sensor 12 fluctuated greatly and malfunctions occurred. In addition, when a catalytic combustion type sensor or the like is used, the sensor generates heat, and if it is housed in the remote control case 9, which is a container with a small heat capacity, there is a problem that the temperature of the entire case rises.

This invention solves these problems,
The purpose of the present invention is to provide an air purifier that is not affected by intake or exhaust air and has stable operating functions.

Means for Solving the Problems In order to solve the above problems, the present invention includes a sensor that detects the degree of pollution of indoor air, and a control circuit that has an automatic operation function that operates in conjunction with the sensor.
It consists of a main body equipped with a switch for operation, etc., and a remote control operation part detachably attached to the main body.The main body has an inclined surface connecting the front surface and the upper surface, or the front surface and the lower surface. It is configured to be attached to a surface.

Effects With the above-described configuration, the present invention allows the sensor output and operational functions to be stabilized without being affected by intake or exhaust air by changing the position of the sensor while allowing the remote controller to be placed in any position and operated. can. Moreover, in this invention, the sensor is attached to the inclined surface connecting the front and top surfaces of the main body, so it is configured on a different surface from the intake or exhaust port, and the airflow flowing to the sensor is disturbed by intake or exhaust air. Never.

Furthermore, the inclined surface is located at a position where cigarette smoke and the like can be sufficiently diffused, thereby increasing sensitivity.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In FIGS. 1, 2 and 3, the main body 19
has a built-in electric blower (not shown), an intake port 20 on the front surface, an exhaust port 21 on the top surface, and a remote control operation section 22 detachably attached. The remote control section 22 is provided with a switch 23 including one for operating automatic driving and an indicator light 24. Main body 1
A gas sensor 25 is provided on the inclined surface 19a connecting the front surface and the top surface of the vehicle 9, and automatic operation is performed based on the output of this sensor 25. 26 is a filter.

In the above configuration, when the operation is explained, when the switch 23 of the remote control operation unit 22 is operated and the automatic operation mode is set, an electric blower (not shown) is activated.
performs automatic operation corresponding to the output of the gas sensor 25. That is, when the gas sensor 25 detects dirt in the indoor air, cigarette smoke, etc., it starts operating, and stops once the air has been purified. At this time,
As shown in FIGS. 2 and 3, the main body 19 is installed upside down when placed on the floor (FIG. 2) and when mounted on the wall (FIG. 3), and the gas sensor 25 is installed diagonally upward as shown in the figure. Dirt such as cigarette smoke is diffused onto the main body 19 and the sensor 25, which are fixed in a downward diagonal direction and placed in a corner of the room as indicated by arrows A and B. In either case, the sensor 25 is provided at a position that is likely to be on a path where dirt is likely to spread, thereby increasing the sensitivity of automatic operation. In addition, the intake port 20 and the exhaust port 2
Since the sensor 25 is attached to a part that is not on the same surface as 1, even if the automatic operation starts, the airflow of the sensor 25 is disturbed by intake and exhaust air, which prevents the operation from becoming unstable. I can do it. In addition, since the gas sensor 25 is built into the main body 19, even if the sensor 25 itself generates heat,
This makes it possible to suppress the rise in temperature of the entire structure and its surroundings. In addition, even if the intake and exhaust airflow slightly disturbs the airflow of the gas sensor 25, the distance and relative positional relationship between the gas sensor 25 and the intake port 20 and exhaust port 21 remain unchanged, so the control circuit, etc. The output of the gas sensor 25 can also be corrected depending on the operating state.

Effects of the invention As described above, according to the invention, by attaching the gas sensor to the main body, the sensor is not affected by intake and exhaust even if the remote control operation part is placed in any position and operated. Furthermore, since the sensor is installed on the slope that connects the front and top surfaces or the front and bottom of the main body, the airflow flowing to the sensor is not disturbed by intake and exhaust, and the slope allows cigarette smoke to be sufficiently diffused. It is possible to provide a high-performance air purifier with high sensitivity.
