Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purifying apparatus for a vehicle for purifying air in a vehicle compartment, and more particularly to an air purifying apparatus for a vehicle which can be operated for a predetermined time after power supply from the vehicle is stopped.

[0002]

2. Description of the Related Art Conventionally, by installing ozone and negative ions in a vehicle such as an automobile,
2. Description of the Related Art Vehicle air purifiers have been used for deodorizing tobacco odors and the like, and for purifying and sterilizing air. here,
In a conventional vehicle air purifier, power is obtained from a cigarette lighter.

However, the conventional vehicle air purifier has the following problems. In other words, when smoking a cigarette, it is necessary to generate ozone or negative ions for a certain period of time in order to eliminate the smell, but after smoking the cigarette, if the ignition switch is turned off when not much time has passed, Since the power supply to the cigarette lighter is naturally cut off, the vehicle air cleaner is stopped. Therefore, there is a problem that the smell of cigarettes remains in the vehicle interior and the smell permeates into sheets and the like. In addition, the next time the vehicle is to be used, smoke or smell of cigarettes remains in the room, causing a problem of discomfort to the occupants. Therefore, a technique has been proposed in which operation is continued for a while even when an ignition switch is turned off as disclosed in Japanese Patent Application Laid-Open No. 9-290629.

That is, in the above publication, a charger and a storage battery are mounted on a deodorizing device, and when an ignition switch is turned on, the deodorizer is operated by supplying power from the vehicle-mounted battery, and at the same time, the storage battery is operated by the vehicle-mounted battery. When the ignition switch is turned off, the power supply from the vehicle battery to the deodorizer and the charger is cut off, and at the same time, the operation of the deodorizer is continued using the charged storage battery until the battery is exhausted. It describes the technique that makes it work.

[0005]

However, in the above-mentioned conventional vehicle deodorizing device, since a charger and a storage battery are mounted, the device is large and heavy, and it is difficult to reduce the size. Since the continuous operation after turning off is performed until the storage battery is exhausted, there is a problem that the operation is wasteful in terms of energy.

Accordingly, the present invention has been made to solve the above problems, and is lightweight and compact, can be used indoors by being detached from a vehicle, and automatically stops driving for a certain period of time. An object is to provide a cleaning device.

[0007]

An air purifying apparatus for a vehicle according to the present invention has a built-in storage battery and is provided in a vehicle so as to be detachable, and generates ozone and negative ions to purify the air inside the vehicle. An air purifying device for a vehicle, comprising: a timer for counting a predetermined time; and after the ignition switch of the vehicle is turned off, the air purifier has a built-in storage battery until the timer counts for a predetermined time. It is characterized by operating by. Therefore, when driving a vehicle,
It runs on electricity supplied from the vehicle's power supply.After the ignition switch is turned off, the timer operates and runs on the built-in battery for the set time, so that the remaining tobacco smoke etc. after the ignition switch is turned off can be removed, and the operation starts. Can be easily set for the desired time, and there is no waste of the built-in storage battery. Therefore, the built-in storage battery can be small, and the entire apparatus can be made small and lightweight.

Further, in the air purifying apparatus for a vehicle according to the present invention, the predetermined time is a time for filling the room with ozone or negative ions. Therefore, the operating time after the ignition switch is turned off can be set according to the size of the indoor volume, so that the vehicle can be widely adapted regardless of the type and size of the vehicle or the indoor size.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a vehicle air cleaning device according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a block circuit diagram of an embodiment of a vehicle air cleaning device according to the present invention. FIG. 2 is a flowchart of an operation program of an embodiment of the vehicle air cleaning device according to the present invention. As shown in FIG. 1, the air cleaning device 10 includes a relay 11 connected to a DC power source 30 of the vehicle, and an air cleaning device 10 connected to the relay 11.
An operation control unit 12 that controls the operation of the air purifier, a built-in storage battery 13 that operates the air purifier 14 when the ignition switch 40 is turned off, or when the power of the air purifier 10 is removed from the cigarette lighter socket 50, Air purifier 14 that generates ozone or negative ions
It is composed of

The power supply of the air purifying device 10 is a D
The C power supply 30 is connected to the cigar lighter 50 via the ignition switch 40 and is input to the relay 11. The relay 11 has a CPU 121, a ROM 122, and an R
The operation control unit 12 including the AM 123 is connected. As will be described later, a program 12 for controlling the operation of the air purifier 14 by turning on and off the power is stored in the ROM 122.
4 are recorded. The timer 123 is stored in the RAM 123.
Is connected to the timer 125 and the air purifier 14
A time setting volume 126 for setting the operating time of the device is connected. The setting of this operation time is performed by the air purifying device 10.
If used for vehicles, between 15 and 30 minutes is sufficient.

The operation of the air cleaning apparatus 10 according to one embodiment of the present invention having the above-described configuration will be described with reference to the flowchart of FIG. At the start,
