Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vehicle-mounted air purifying device, and more particularly to a vehicle-mounted air cleaning device that is attached to a vehicle and purifies the interior of the vehicle.

Conventional technology In recent years, the number of in-vehicle air purifiers that purify the smoke and odor of cigarettes inside the car has increased, and many are installed in the tray, others are installed on the ceiling inside the car, or the device is not installed in the car. There is.

Problems to be Solved by the Invention As described above, the main body of the air purifying device installed in the car has intake and exhaust ports and is placed at a specific position in the car, so it is difficult to quickly remove cigarette smoke, etc. there were. That is, since the air purifying device main body needs to be downsized due to the space inside the vehicle, it cannot be set to a size that has sufficient air purifying ability.

In addition, if the smoke is installed on the floor or in the rear tray, the smoke that has spread inside the car will be gradually purified.

Therefore, non-smokers in the vehicle will also inhale smoke until the smoke is purified.

SUMMARY OF THE INVENTION An object of the present invention is to provide an on-vehicle air cleaning device that eliminates such inconveniences and has high purification ability without narrowing the interior space of the vehicle.

Means for Solving the Problems In order to achieve the above object, the in-vehicle air purifying device of the present invention has an air inlet and an exhaust port, and has a built-in filter and a fan driven by a motor. An air injection unit is installed in the ceiling of the car interior, and smoking seats and non-smoking seats are separated by an air curtain.Intake grilles are placed separately within the area partitioned by this air curtain. The intake grille and the air injection part are communicated with the intake port and the exhaust port of the air purifier main body through ducts, and a smoke sensor is disposed in each of the intake grilles to purify the air in the smoking seat. It is something.

Further, the air injection part is communicated with the air conditioner of the vehicle, and the exhaust port of the air purifying device main body is communicated with an exhaust grill facing the rear tray via a duct.

Operation With the above-described configuration, the in-vehicle air purifying device of the present invention can be installed in the trunk room, and the air purifying device body can be set to have a high purifying ability without narrowing the interior space of the vehicle, and can be installed on the ceiling of the vehicle interior. An air injection section is provided to separate smoking seats and non-smoking seats with an air curtain, and intake grills are arranged separately within the area partitioned by the air curtain, and a smoke sensor detects smoking to remove smoke from the air. Driving the main body of the depletion cleaning device and forming the air curtain with the exhaust flow,
The smoke generated in the space partitioned by the air curtain is sucked in and purified by opening the intake grill in that area. Therefore, the air cleaning space is limited and small, and dirty air can be quickly cleaned, and after cleaning, the drive of the air cleaning device body is stopped by the smoke sensor. This air curtain separates smoking seats from non-smoking seats, allowing non-smokers to stay comfortably without inhaling smoke. Furthermore, if the air injection section is connected to the car's air conditioner, the temperature of the air curtain to be injected can be selected and comfortable air conditioning in the car can be achieved.

Embodiment Hereinafter, a vehicle air cleaning device according to an embodiment of the present invention will be explained based on the drawings. As shown in Figure 1, there is an intake port 1 in the trunk of a car. An air purifying device main body 3 having an exhaust port 2 is disposed, and a filter, a fan driven by a motor, and the like for air purifying function are built into the main body. An air injection part 5 is attached to the ceiling 4 of the car, and in the case shown in the figure, it is formed into a nearly cross shape that divides the lower seats horizontally, and has a large number of small holes arranged downward. ing. Each area divided by this air injection part 5 has an intake grid /l/6 divided intake grids IJ /ea, e.
b, ec, and 6d are provided, and a smoke sensor 7 is arranged in each. The intake grille 6 and the air injection part 6 are communicated with the intake port 1° and the exhaust port 2 of the main body 3 through ducts 8 and 9, respectively. The smoke sensor 7 sends a signal to the control circuit 1o built in the main body 3 as shown in FIG.
J) 6a.

eb, ec, and ad intake valve IJ/opening/closing motor 11
Drive to open and close. In this way, when someone smokes in the car, the smoke sensor 7 on the smoking seat detects this and drives the fan drive motor 12 of the air purifier main body 3, and the exhaust flow passes through the duct 9 to the air injection section. 6, air is blown out from numerous small holes, and each seat below is partitioned off by an air curtain. On the other hand, the smoke sensor detects a smoking seat, opens only the intake valve in that area to suck in smoke, and the purified air is circulated back into the car as an exhaust stream. When the air inside the vehicle becomes clean, the smoke sensor 7 sends a signal to the control circuit 1Q, the fan drive motor 12 is stopped, and the air cleaning ends. By partitioning each seat with an air curtain in this way, the air purification space is limited and small, and dirty air can be quickly purified.The front seats for smoking and non-smokers are separated, so non-smokers can You can maintain a comfortable state without inhaling.

Next, FIG. 3 will be explained. Components that are the same as those in FIG. 1 are designated by the same reference numerals. An air injection part 6 attached to the ceiling part 4 of the car is communicated with an air conditioner 13 through a duct 14, and exhaust from an air purifying device main body 3 placed in the trunk room is communicated with an exhaust grill 6 facing the rear tray. In this way, the temperature of the air curtain injected from the air injection part 5 communicating with the air conditioner 13 can be selected, and air purification can be performed while providing comfortable air conditioning in the vehicle.

Effects of the Invention As is clear from the description of the embodiments below, according to the in-vehicle air purifying device of the present invention, the main body is located in the trunk room and has a high purifying ability, that is, a high air volume, without narrowing the interior space of the vehicle. The air curtain can be used to partition the interior space of the car, reducing the air purification space to a small size, quickly purifying dirty air, and separating the smoking and non-smoking seats so that non-smokers can avoid smoking. You can maintain a comfortable state without inhaling.

Furthermore, by communicating the air conditioner with the air injection section, the temperature of the air curtain can be selected, and an on-vehicle air purifying device can be provided that can purify the air while providing comfortable in-vehicle air conditioning. Note that this content is applicable not only to ordinary passenger cars but also to one-box cars, buses, etc. that accommodate a large number of passengers.
