[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle deodorizing device for deodorizing the interior of a vehicle using an ozone generator, and more particularly to a vehicle having a high deodorizing efficiency and capable of efficiently deodorizing a vehicle having a large space such as a bus. In addition, the present invention relates to a deodorizing device for a vehicle that can ensure the safety and comfort of passengers in a passenger compartment after deodorizing.

2. Description of the Related Art In vehicles such as buses that carry many passengers,
A unique smell is trapped in the cabin due to the sighs of passengers and smoke from cigarettes, which may cause motion sickness. Therefore, conventionally, it has been common practice to deodorize the vehicle interior with a deodorizing tool using activated carbon, or to deodorize the vehicle interior by spraying an aromatic.

However, simply installing an ozone generator in a vehicle compartment cannot efficiently deodorize a vehicle compartment such as a bus with a large space. Also, since ozone is extremely toxic and has a unique ozone odor even at an extremely low concentration, if ozone remains in the passenger compartment after deodorization, it may impair passenger safety and comfort. It is necessary to take countermeasures.

Accordingly, the present invention provides a deodorizing apparatus for a vehicle which can efficiently deodorize a large cabin such as a bus using an ozone generating device, and can also ensure the safety and comfort of passengers in the cabin after deodorizing. The purpose is to provide.

That is, when the changeover switch 43 is switched to the selected position of the residual ozone discharge mode, the ozone generator 10
The operation is stopped, until the elapse of the set time t _2, cooling device 5 or heating device 7 of the air conditioner ventilation device 9 while operating in the outside air introduction mode is operated with the inside air discharge mode. Therefore, fresh air outside the vehicle is introduced into the vehicle interior 3 by the cooling device 5 or the heating device 7, and the air inside the vehicle interior 3 containing the residual ozone gas is forcibly discharged outside the vehicle by the ventilation device 9.

Alternatively, the control may be changed to the operation in which the heating device 7 is operated only in the outside air introduction mode.

In this case, when the residual ozone discharge mode is selected, the operation of the ozone generator 10 is stopped, and the cooling device 5 or the heating device 7 of the air conditioner is operated until the set time t ₂ elapses. It operates in the outside air introduction mode to introduce fresh air outside the vehicle into the vehicle interior 3, and the air in the vehicle interior 3 containing the residual ozone gas is cooled by the cooling device 5 or the heating device 7.
As a result, the air is discharged to the outside of the vehicle while being diluted with the fresh air introduced into the vehicle interior 3, and thus the safety and comfort of the passenger in the vehicle interior 3 after the deodorization are secured.

Further, in FIGS. 12 and 15 showing the control flow of the first embodiment and the second embodiment, the control of step 4 in the deodorizing mode is performed by turning on the power of the ozone generator 10 and activating it. In addition, the control is changed to only the operation of the ventilator 9 in the outside air introduction mode, and the control of Step 8 in the residual ozone discharge mode is performed by turning off the power of the ozone generator 10 and stopping the operation, and turning the ventilator 9 on. The control may be changed to only operate in the inside air discharge mode.

In this case, when the deodorizing mode is selected, the ozone generator 10 operates and the ventilator 9 operates in the outside air introduction mode, and the ozone gas generated in the vehicle compartment 3 by the ozone generator 10 is ventilated. The air is sent out to various parts in the vehicle compartment 3 together with the air outside the vehicle introduced by the device 9, so that the interior of the vehicle compartment 3 is efficiently and easily deodorized over a wide range. Also, when the residual ozone emission mode is selected,
Until the operation of the ozone generator 10 stops and the set time t ₂ elapses, the ventilator 9 operates in the inside air discharge mode to forcibly discharge the air in the passenger compartment 3 containing the residual ozone gas to the outside of the vehicle. In this case as well, the safety and comfort of the passengers in the passenger compartment 3 after the deodorization are ensured.

As described above, according to the first aspect of the present invention, when the deodorizing mode is selected by the switch means, the operation control means operates the ozone generator and the air conditioner in the inside air circulation mode. As a result, ozone is generated in the vehicle interior, and the air in the vehicle interior containing the ozone circulates in the vehicle interior, so that the vehicle interior can be efficiently and easily deodorized over a wide range.

When the residual ozone discharge mode is selected by the switch means, the operation control means stops the operation of the ozone generator, activates the air conditioner in the outside air introduction mode, and activates the ventilator. Fresh air outside the vehicle is introduced into the cabin, and air inside the cabin containing residual ozone is forcibly discharged out of the vehicle, ensuring sufficient safety and comfort for passengers in the vehicle after deodorization. be able to.

As another configuration, when the deodorizing mode is selected by the switch means, the operation control means activates the ozone generator and the air conditioner in the inside air circulation mode. Is generated, and the air in the vehicle interior containing the ozone circulates in the vehicle interior, so that the vehicle interior can be efficiently and easily deodorized over a wide range.

When the residual ozone discharge mode is selected by the switch means, the operation control means stops the operation of the ozone generator and activates the air conditioner in the outside air introduction mode, so that fresh air outside the vehicle is left in the vehicle interior. The air is introduced, and the air in the vehicle compartment containing the residual ozone is discharged outside the vehicle. In this case as well, the safety and comfort of passengers in the vehicle compartment after deodorization can be sufficiently ensured.

According to the second aspect of the present invention, when the deodorizing mode is selected by the switch means, the operation control means activates the ozone generator and the ventilator in the outside air introduction mode. Ozone is generated in the cabin, and this ozone is sent out to various parts in the cabin together with the air outside the car introduced by the ventilator, so that the car cabin can be efficiently and easily deodorized over a wide range.

When the residual ozone discharge mode is selected by the switch means, the operation control means stops the operation of the ozone generator and activates the ventilator in the inside air discharge mode, whereby the inside of the vehicle cabin containing the residual ozone is released. The air is forcibly discharged to the outside of the vehicle, and similarly, it is possible to sufficiently secure the safety and comfort of the passengers in the vehicle compartment after the deodorization.

According to the third aspect of the present invention, even if the deodorizing mode is selected by the switch means, the selection of the deodorizing mode is not executed when the parking brake is not operated or the traveling engine is not stopped. Therefore, there is a high possibility that a situation in which the deodorization mode is erroneously selected when the passenger is driving or temporarily stopping the vehicle in the vehicle interior and ozone is generated in the vehicle interior is prevented beforehand,
High security can be ensured.

According to the fourth aspect of the present invention, when the deodorizing mode is selected by the switch means, the timer sequentially selects the residual ozone discharging mode and the stop mode successively after the selection, so that a series of deodorizing operations can be continuously performed. Operation is extremely simple.
