Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-vehicle air purifier for cleaning the air inside a vehicle.

[0002]

2. Description of the Related Art In a conventional on-vehicle air purifier, as shown in FIG. 3, an air purifier 1 is installed in a trunk room behind a vehicle. Since it takes time to reach the smoke sensor 4 in the device 1, there is a problem that the high-speed operation of the blower of the air cleaner 1 (hereinafter, referred to as a cleaning operation) is delayed.

Therefore, the blower built in the air purifier 1 is constantly operated at a low speed, and the smoke generated by smoking in the front seat is passed through the suction port 7 of the air purifier 1 as shown by the arrow in FIG. It is led to the smoke sensor 4.

[0004]

However, in the above method, in the foot mode, the wind from the air conditioner short-circuits at the foot of the front seat, and the smoke generated by smoking in the front seat is blocked by this wind. Therefore, there is a problem that the cleaning operation of the air purifier is delayed in the foot mode because it becomes difficult to flow backward.

On the other hand, in order to solve the above problem, it is possible to separate the smoke sensor from the air purifier and mount it near the front seat, but for that purpose, a wiring dedicated to the smoke sensor is required, so the air purifier is required. It is common to install a smoke sensor inside.

The present invention has been made in view of the above points, and the smoke generated by smoking in the front seat is sent to the smoke sensor in the air purifier at the rear of the vehicle without being obstructed by the wind of the air conditioner. The purpose is to eliminate the delay in the cleaning operation of the air purifier by promptly guiding.

[0007]

In order to achieve the above object, the present invention provides: (1) a blower installed in the rear of a vehicle,
In an on-vehicle air purifier with a built-in purification filter and smoke sensor, and an air intake and an air outlet, an auxiliary suction port provided separately from the suction port and connected to this auxiliary suction port And an auxiliary suction duct that is provided, wherein the auxiliary suction duct is connected to a gap between a ceiling interior plate and an ceiling outer plate having an opening in the front of the vehicle compartment of the vehicle. In addition, you may use the technical means of the structure which penetrates the said auxiliary suction duct through the said gap to the vicinity of the said opening part.

[0008]

According to the above means, by constantly operating the blower in the air purifier at a low speed, the smoke generated by smoking in the front seat is transferred to the ceiling outer plate through the opening provided in the ceiling inner plate. Since it passes through the auxiliary suction duct through the gap with the ceiling interior board and is introduced into the air purifier from the auxiliary suction port, smoke is not blocked by the wind of the air conditioner, and the smoke sensor in the air purifier can be used for a short time. Since it arrives at, the arrived smoke is detected by the smoke sensor, and the cleaning operation of the air purifier is immediately started.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An on-vehicle air purifier according to the present invention will be described below with reference to the embodiments shown in FIGS.

In FIG. 1, reference numeral 10 denotes a main body case of the air purifier 1, which is attached to a rear tray 11 via a suction duct 5 and a blowing duct 6, and the suction duct 5 is a grill or the like communicating with the vehicle interior. The outlet duct 6 is connected to the inlet 7, and the outlet duct 6 is connected to an outlet 8 having a grill or the like that is also in communication with the vehicle interior.

Inside the main body case 10 below the suction duct 5, there is provided a blower 2 that sucks air from the suction port 7 and blows air from the blowout port 8, and inside the main body case 10 below the blowing duct 6. Is provided with a filter 3 for purification of activated carbon fibers or the like that adsorbs smoke components and odor components of cigarettes in the air, and the main body case 1 located upstream of the filter 3
Inside 0, a smoke sensor 4 for detecting smoke components in the air is arranged.

Here, an auxiliary suction port 9 is opened on the side surface of the suction duct 5, and an auxiliary suction duct 12 which will be described later is connected to the auxiliary suction port 9 so that the air purifier 1 is constructed. ing.

As shown in FIG. 2, the auxiliary suction duct 12 is connected to the gap between the ceiling outer plate 13 and the ceiling inner plate 14 of the vehicle, and is located in the front of the ceiling inner plate 14 in the vehicle interior. An opening 15 made of a slit or the like is formed in the portion.

Next, the operation of the above embodiment will be described. The blower 2 shown in FIG. 1 is constantly operating at a low speed,
Therefore, as shown in FIG. 2, the air in the passenger compartment is the same as the air flow indicated by arrow A, which is guided to the suction duct 7 of the air purifier 1.
Gap 1 between the ceiling outer plate 13 and the ceiling inner plate 14 from the opening 15
A flow of arrow B guided from the auxiliary suction duct 12 to the auxiliary suction port 9 of the air purifier 1 via 6 is generated.

Here, the smoke generated by smoking in the front seat is
The air is sucked from the opening 15 of the ceiling interior plate 14 opened near the upper part of the front seat and is introduced into the air purifier 1 through the auxiliary suction port 9 along the air flow indicated by the arrow B in a short time.

As shown in FIG. 1, the air of the arrow B containing the cigarette smoke introduced into the air purifier 1 merges with the air of the arrow A introduced from the suction port 7, and becomes the air of the arrow C. Then, since the smoke sensor 4 is touched, the smoke component of the cigarette contained in the air indicated by the arrow C is detected by the smoke sensor 4.

Here, when smoke is detected, a signal is sent from the smoke sensor 4 to a control circuit (not shown), and the blower 2 starts to operate at high speed according to an instruction from the control circuit. The air in the passenger compartment is quickly cleaned by the filter 3 and becomes the cleaned air indicated by the arrow D and is blown into the passenger compartment from the air outlet 8. Therefore, the air in the passenger compartment is quickly cleaned.

As shown in FIG. 2, since the smoke generated by smoking in the front seat flows along the air flow indicated by arrow B, the air flow of the air conditioner does not impede the flow, while the rear seat Most of the smoke generated by smoking flows along the air flow indicated by the arrow A. Therefore, even if the smoke is smoked individually or simultaneously in the front seat and the rear seat, the generated smoke will remain in the air purifier 1 for a short time. In this case, the cleaning operation of the air purifier 1 is immediately started, and the effect of reducing the deviation of the cleaning degree of the air in the vehicle interior is also obtained.

Next, in this embodiment, the auxiliary suction duct 12
Was connected to the gap 16 between the ceiling outer plate 13 and the ceiling interior plate 14, but the auxiliary suction duct 12 was inserted into the gap 16 up to the vicinity of the opening 15 formed in the ceiling interior plate 14. Good.

Further, in this embodiment, the auxiliary suction port 9 is provided on the side surface of the suction duct 5, but if it is located at a position different from the suction port 7 and on the upstream side of the blower 2, the air purifier 1 is not provided. You can open it anywhere.

In this embodiment, the on-vehicle air purifier having the suction duct 5 and the blow-out duct 6 has been described, but it is of course applicable to the on-vehicle air purifier not having the suction duct 5 and the blow-out duct 6. Is something that can be done.

[0022]

As described above, according to the present invention, the smoke generated by smoking in the front seat in the passenger compartment is located in the air purifier behind the vehicle from the auxiliary suction duct provided independently. In a short time, the smoke sensor detects the smoke and starts the cleaning operation of the air purifier, so that the air is blocked by the air from the air conditioner and the smoke detection is delayed, which causes the air cleaner to operate. Is no longer delayed and the air in the passenger compartment is quickly cleaned.
