FIG. 1 is a schematic view showing an example of an arrangement of a vehicle-mounted air cleaner according to the present invention.

In FIG. 1, an on-vehicle air purifier 1 is arranged on a rear tray 3 behind a rear seat (not shown) of a passenger car 2.

FIG. 2 is a schematic plan view showing an embodiment of the vehicle air cleaner 1.

The vehicle air purifier 1 draws air from one of the left and right directions with respect to the traveling direction of the passenger car 2,
The air is blown out from the other side. A fan 11 is provided at the center, and filters 12 and 13 are provided on the upstream side and the downstream side with respect to the fan 11.
Is provided. In this embodiment and the following embodiments, various conventionally known filters can be used as the filters 12 and 13.

When this configuration is employed, as shown in FIG. 1, the air purifier 1 for the vehicle achieves a horizontal air suction and a horizontal air blow. Therefore, the lateral air flow formed by the vehicle air cleaner 1 is hardly obstructed by the seat. Also,
In a passenger car, an air conditioner (not shown) is provided in the entire boarding space, and an air flow formed by the air conditioner is a vertical flow (see FIG. 1). Specifically, when the distribution of the inside air circulation airflow velocity blown out to the front window was measured, as shown in FIG. 3, the airflow velocity of each part in the upper part of the boarding space was obtained, and the airflow velocity in the vertical direction (the central airflow velocity) was obtained. It can be seen that the air velocity in the lateral direction (air velocity in the side window portion) is significantly smaller than the air velocity (air velocity). Therefore, the lateral airflow formed by the vehicle air cleaner 1 is hardly affected by the airflow formed by the air conditioner.

In this embodiment, the direction of air suction and the direction of air blow can be set opposite to the above, and in this case, the same operation can be achieved.

As a result, stagnation of air near the front seat can be prevented, and the boarding space can be efficiently cleaned.

FIG. 4 is a schematic plan view showing another embodiment of the vehicle air cleaner 1.

The on-vehicle air purifier 1 is configured to blow air from the left and right directions and suck air from the center with respect to the traveling direction of the passenger car 2, and has a fan 11 at the center. In addition, the filters 12 and 1 are located on the left and right sides with respect to the fan 11.
3 are provided. Here, the air suction direction in the central portion can be exemplified by horizontal front, upper, horizontal rear, and the like.

When this configuration is adopted, the flow of the suction air is somewhat affected by the air flow formed by the air conditioner, but the flow of the blown air (clean air) is formed by the air conditioner. Hardly affected by the flow of air. Of course, any airflow is hardly obstructed by the seat.

Therefore, it is possible to prevent stagnation of air near the front seat, and to efficiently clean the boarding space.

FIG. 5 is a schematic plan view showing still another embodiment of the on-vehicle air purifier 1.

The on-vehicle air purifier 1 is configured to blow air from the left and right directions with respect to the traveling direction of the passenger car 2 and to suck air from the center. A fan 11 is provided at the center. In addition, the filters 12 and 1 are located on the left and right sides with respect to the fan 11.

A detection unit (not shown) is provided. Here, the detection unit includes, for example, a first detection unit that detects contamination caused by particles and a second detection unit that detects contamination caused by odor, and detects output signals from both detection units. A signal output as a signal can be exemplified, but is not limited to this configuration, and various configurations can be adopted. In addition, a deodorizing filter (a filter for removing odor) is used as the filter 12, and a particle filter (a filter for removing particles) is used as the filter 13.

FIG. 6 is a flowchart for explaining an example of the control of the vehicle air cleaner of FIG.

In step SP1, it is determined based on the output signal from the detection unit whether the cause of the contamination of the intake air is particles, smell, or almost no contamination, and the cause of the contamination of the intake air is particles. Is determined, or when it is determined that there is almost no contamination, step SP
2, a damper 14 provided between a fan 11 and a filter 12 (a deodorizing filter made of activated carbon or the like).
(Damper for deodorizing filter) is closed. Conversely, if it is determined that the cause of contamination of the intake air is odor,
In step SP3, the fan 11 and the filter 13
The damper 15 (a damper for the particle filter) provided between the damper 15 and the (particle filter) is closed. And step SP
The damper control process is completed by performing the process of 2 or step SP3.

The processing of the flowchart of FIG. 6 may be performed periodically, but may be performed in response to an instruction at a desired timing.

In the processing of the flowchart of FIG.

When this configuration is employed, the cause of the intake air contamination can be determined from the output signal from the detection unit,
The dampers 14 and 15 can be selectively operated based on the determination result, and the air can be purified using a filter suitable for the cause of the contamination. Further, unnecessary depletion of the deodorizing filter or the like can be prevented, and re-scattering of contaminants can be prevented when the filter is not dirty.

In the embodiment shown in FIGS. 2 and 4, if the filters 12 and 13 are made replaceable with different types of filters, the filters 12 and 13 are replaced to obtain the same configuration as the embodiment shown in FIG. Action can be achieved.

Further, the degree of contamination of the intake air is detected, and the rotational speed of the fan 11 is controlled in response to the detection result, or the opening of the damper is controlled, thereby controlling the flow rate of the blown air. Is preferable, and an air purification effect corresponding to the degree of contamination can be achieved.

Further, it is possible to employ a temperature sensor as the detection unit and perform control based on an output signal from the temperature sensor. In addition, it is possible to control the opening and closing of the damper, adjust the odor concentration, and the like, by predicting the amount of dirt and / or odor re-scattered from the filter. Further, the filters include dirt and / or
Alternatively, when removing odors or the like rapidly, the high-performance H
For example, a combination of EPA and activated carbon or a combination of a medium-performance filter and activated carbon can be used. In normal operation, only a medium-performance filter, a combination of a medium-performance filter and a photocatalyst, or a photocatalyst is used. Can be exemplified. By selectively operating the filter at the time of rapid removal and the filter at the time of normal operation, the life of each filter can be extended.
