DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing fragrance device for a vehicle, and more particularly to a deodorizing fragrance device for a vehicle having a function of automatically stopping deodorization and fragrance when smoking in a passenger compartment.

[0002]

2. Description of the Related Art Generally, a vehicle is provided with an ozonizer for generating ozone, an ozone decomposing catalyst for decomposing ozone so as not to be released into the vehicle compartment, and a blower fan for purifying inside air and discharging the air into the vehicle compartment. 2. Description of the Related Art There are known aroma deodorizing devices, vehicular aroma devices that include an aroma device that emits various aromas, and a blower fan, mix aroma into indoor air and discharge the aroma into a vehicle interior. These are used independently or in combination.

[0003]

However, in the conventional deodorizing apparatus, if the user smokes in the passenger compartment while the deodorizing apparatus is in operation, nitric oxide (NO) and ozone (O) generated during smoking are generated.
₃ ) reacts with nitrogen dioxide (NO ₂ ) harmful to the human body
There is a problem that occurs.

[0004] Further, in the conventional fragrance device, there is a problem that when smoking in the vehicle interior while the fragrance device is in operation, the tobacco odor and the fragrance are mixed and the odor is rather generated.

In order to solve this problem, nitrogen dioxide (N
An alkaline filter for removing O ₂ ) may be provided, but this increases the pressure loss and causes a problem that the filter must be replaced periodically.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a deodorizing fragrance apparatus for a vehicle which solves the above-mentioned problems of the conventional technology and does not generate harmful nitrogen dioxide (NO ₂ ) or odor. Is to do.

[0007]

In order to achieve the above object, the present invention provides an ozonizer that generates ozone, an ozone decomposition catalyst that decomposes ozone so as not to be released into a vehicle interior, and a blower fan. In a vehicle deodorizing device for purifying inside air and discharging it into the vehicle interior, a sensor for sensing smoking and a sensor for sensing the end of smoking are provided, and a period from when smoking is sensed to when the end of smoking is sensed is provided. Is characterized in that the ozonizer and the blower fan are stopped.

Another aspect of the present invention is a vehicular aroma device that includes an aroma device that emits various aromas and a blower fan and mixes aroma into inside air and discharges the aroma into a vehicle interior. A sensor for sensing the end of smoking is provided, and the fragrance device and the blower fan are stopped from when the smoking is sensed to when the end of the smoking is sensed.

[0009]

According to the present invention, an ozonizer and a blowing fan, or an aroma unit and a blowing fan are provided between the time when smoking is sensed by the sensor for sensing smoking and the time when smoking is sensed by the sensor for sensing end of smoking. Is stopped, so that no harmful nitrogen dioxide (NO ₂ ) or odor is generated to the human body, and the air conditioning in the vehicle compartment is extremely comfortable.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a deodorizing fragrance device for a vehicle according to the present invention will be described below with reference to FIGS.

In FIG. 1, 1 indicates a deodorizing unit and 3 indicates an aroma unit.
Is configured to fit the fragrance unit 3 into the recess 1a. In the deodorizing unit 1, as shown in FIG.
12 [V] A control unit 11 including a power source E is provided. The control unit 11 is connected to an ozonizer 13 for generating ozone via a transformer 12 and a blower for generating an air flow in the direction of arrow A. The fan 15 is connected.
Reference numeral 16 denotes an ozone decomposition catalyst that decomposes ozone so that it is not released into the vehicle compartment.

Further, according to this embodiment, a flame sensor 17 having a fast response for sensing smoking is provided.
A gas sensor 19 for sensing the end of smoking is provided,
These are connected to the control unit 11 respectively. The flame sensor 17, are used such as via infrared, to the gas sensor 19, a semiconductor gas sensor for detecting the mainstream smoke, which detects the components contained in sidestream smoke (resistance change in the S _n O ₂ in cigarette ) Or a constant potential electrolytic NO ₂ sensor.

Next, the operation of the embodiment will be described with reference to FIG.

When the power supply E is turned on after the start (step 1), a timer in the control unit 11 is operated (step 2). This timer is a three-hour timer. During this time, first, the presence or absence of smoking is continuously checked by the flame sensor 17 (step 3). If there is no smoking, deodorization is started (step 4), and thereafter, control is performed in the deodorization mode (step 5). This deodorizing mode uses ozone (O
After purifying the inside air using an ozonizer 13 that generates ₃ ), an ozone decomposition catalyst 16 that decomposes ozone (O ₃ ) so as not to be released into the vehicle compartment, and a blower fan 15, Is released into the vehicle interior.

After shifting to the deodorizing mode, it is checked whether or not three hours have elapsed (step 6). If it is before three hours, it is checked whether or not smoking has occurred (step 7). If there is no smoking, the deodorizing mode is set. maintain. If 3 hours have elapsed (step 6), the deodorization is stopped unless the operation is started again.

According to this embodiment, if it is checked in step 7 that there is smoking, the deodorization is stopped (step 8). In this case, power supply to the ozonizer 13 and the blower fan 15 is cut off. Also, since the interior of the vehicle is normally naturally ventilated, the gas concentrations of NO, NO ₂ , tobacco odor and the like are considered to decrease rapidly. Therefore, the gas concentration in the vehicle compartment is detected (Step 9), and when it is determined that the gas concentration is equal to or lower than the predetermined concentration, the gas is reset and the process returns to Step 2 again. Note that the gas concentration is detected via the gas sensor 19.

According to this, since the deodorization is stopped during smoking, ozone (O ₃ ) is not generated, and the dioxide generated by the reaction between ozone (O ₃ ) and nitric oxide (NO) is not generated. Generation of nitrogen (NO ₂ ) can be reliably suppressed. Further, the tar component and other organic components in the tobacco do not adhere to the ozone decomposition catalyst 16, and the performance degradation of the catalyst can be reliably prevented.

When smoking in a passenger compartment, the user usually smokes with the window opened. In such a case, even if the deodorizing device is activated, it is not effective. No problem arises.

FIG. 4 shows the fragrance unit 3. The fragrance unit 3 includes a control unit 31 including a 9 [V] power source E.
The controller 31 is connected to a blower fan 33 that generates an air flow in the direction of arrow B. In addition, the fragrance unit 3 includes an fragrance device 3 that emits various fragrances.
5a to 35c are provided, and various fragrances can be extracted by selecting a fragrance with the fragrance selection button 36. Further, similarly to the above-described embodiment, a flame sensor 37 having a fast response for detecting smoking and a gas sensor 39 for detecting the end of smoking are provided, and these are connected to the control unit 31. .

The operation of this embodiment is almost the same as that of the above embodiment. As shown in parentheses in FIG. 3, in steps 4, 5, and 8, deodorization simply replaces fragrance.
According to this, the aroma is stopped during smoking, so that the tobacco smell and the aroma do not coexist, and the generation of offensive odor can be reliably suppressed.

[0021]

As is apparent from the above description, according to the present invention, a sensor for sensing smoking and a sensor for sensing the end of smoking are provided. During that time, the ozonizer and blower fan, or the fragrance device and blower fan were stopped, so that no harmful nitrogen dioxide or odor was generated to the human body, and comfortable air conditioning in the cabin was achieved. it can.
