Abstract

PURPOSE:To reduce noise by disposing a motor, a fan, a scroll and a dust collecting mechanism inside of a door and side panels. CONSTITUTION:Fans 7 are rotated by motors 6 disposed inside of a plurality of doors, and air 10 is sucked up from the passenger compartment by scrolls 8. The sucked up air is led through a filter 4 so that bulky dust is caught thereby, and is then led through an electric dust collecting part 5 where fine dust such as smoke particles are electrically attracted so that the air is turned into purified air which is then discharged from a discharge port 2. With this arrangement, air is efficiently substituted around a passenger, and is divided into several streams, thereby it is possible to divide and reduce the flowing sound of the air, the operating sound of the motor and the like.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to noise reduction and improvement of efficiency of replacement of indoor air with purified air in an automobile air cleaning apparatus.

[0002]

2. Description of the Related Art As disclosed in Japanese Patent Laid-Open No. 62-116307, a conventional apparatus has a plurality of outlets, but has only one electric motor and one dust collecting mechanism to replace the air inside the vehicle. However, the electric motor needed more power than necessary and generated a lot of noise.

[0003]

In the above-mentioned prior art, one vehicle has one air cleaner (there is only one electric motor and one dust collecting mechanism).
The problem was that the space and sound increased in proportion to the performance.

An object of the present invention is to provide an air purifier for each seat so that each electric motor and dust collecting mechanism can be made compact and provide a clean air cabin with low noise.

Another object of the present invention is necessary for safe driving,
The defrost of the side window is performed by using the air blowing function of the air cleaning device.

[0006]

In order to achieve the above object, a brushless flat motor is used as an electric motor, and a fan, a scroll, and a dust collecting mechanism are configured to have a thickness that can be stored in a vehicle door.

[0007]

[Function] The vehicle door not only houses the window glass, but also the speaker, magazine tray, power window motor,
A large number of door lock motor actuators and the like are stored, but if the air cleaning device can be constructed with a thickness of 60 mm, it can be stored in the door. This means that air can be efficiently replaced near the occupant, and
By dividing into multiple parts, the flow noise of the air, the operating noise of the motor, etc. are divided and reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

1 and 2 are a plan view and a side sectional view of an automobile, showing the positions of a smoke sensor 1 and an exhaust port 2 and an intake port 3 of an air cleaning device.

FIG. 3 is an external view of an automobile door and shows the positions of the filter 4 and the electrostatic precipitator 5. 11 is a speaker.

FIG. 4 is a sectional view taken along the line AA of FIG. 3, showing the electric motor 6, the fan 7 and the scroll 8. Reference numeral 10 is intake air, and 9 is exhalation air.

FIG. 5 is a connection diagram of a control mechanism, which includes a 61 battery, a 62 room lamp, a 63 door sensor (there are plural in parallel), a smoke sensor, a 65 timer, a 66 automatic, a manual changeover switch, and a 67 window sensor. , A state where a plurality of electric motors 6 and electric dust collecting units 5 are arranged in parallel are shown.

FIG. 6 shows the details of the electric dust collecting portion. Reference numeral 51 is a dust collecting plate, 52 is an ionizing plate, and 53 is a lattice-shaped magnetic shield, which is integrated with the dust collecting plate 52. Next, the operation of the air cleaning device having the above structure will be described.

With an ignition key (not shown),
When electric power is received from the battery 61 and the automatic / manual changeover switch 66 is in the manual mode, the electric motor 6 installed in the plurality of doors rotates the fan 7 and sucks the air 10 in the vehicle compartment by the scroll 8. The sucked air removes coarse dust with the filter 4, and fine dust such as smoke particles is electrified by the ionization plate 52 of the electrostatic precipitator 5, and the fine dust electrified on the dust collector plate 51 is electrodeposited and cleaned. The air is discharged from the air outlet 2. The discharged air acts as a defroster that eliminates window fog.

In the automatic case, the door sensor 63 (the air cleaning device does not turn on when the door is open) and the window sensor 67 (the air cleaning device does not turn on when the window is open) are checked. , Smoke sensor 1
As a result, the air cleaning device is activated by detecting a light-shielding substance such as cigarette smoke. At the same time, even if the smoke sensor 1 is in an inactive atmosphere, the timer 65 causes the air cleaning device to operate for a certain period of time when the ignition key is pressed and a certain period of time has elapsed.

[0016]

Since the present invention is constructed as described above, it has the following effects.

1. It can be integrated with the car by storing it inside the door.

2. Cigarette smoke does not flow to other occupants and does not cause discomfort to other occupants.

3. Since the amount of air passing through one intake port is one-fourth that of an air purifier having the same capability as before, air flow noise and electric motor noise are reduced.

4. Side air defrosting is possible with exhaled air.
