[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle deodorizing device for deodorizing an interior of a vehicle by utilizing an ozone generator, and in particular, it has a high deodorizing efficiency and can efficiently deodorize the interior of a vehicle having a large space such as a bus. At the same time, the present invention relates to a vehicle deodorizing device capable of ensuring the safety and comfort of passengers in a vehicle after deodorization.

2. Description of the Related Art In vehicles such as buses that carry many passengers,
A peculiar odor may be trapped in the passenger compartment due to passengers' breath or cigarette smoke, and this odor may cause car sickness. Therefore, conventionally, it has been generally practiced to deodorize the vehicle interior with a deodorizing tool that uses activated carbon, or to deodorize the vehicle interior by spraying an aromatic agent.

However, simply installing the ozone generator in the vehicle compartment cannot efficiently deodorize the vehicle compartment such as a bus having a large space. In addition, ozone is extremely toxic and has a unique ozone odor even at an extremely low concentration, so if ozone remains in the passenger compartment after deodorization, it may impair the safety and comfort of passengers. That measure is necessary.

Therefore, the present invention makes it possible to efficiently deodorize a large passenger compartment such as a bus using an ozone generator, and to ensure the safety and comfort of passengers in the passenger compartment after deodorization. The purpose is to provide.

In response to this, the changeover switch 43 is
The operation control means has three switching positions for outputting selection signals corresponding to the deodorizing mode, the residual ozone discharging mode, and the stop mode, and is arranged on an instrument panel (not shown) in the driver's seat. Further, the parking brake actuation detection switch 44 outputs an ON signal when a parking brake (not shown) is activated, and the running engine stop detection switch 45 outputs an ON signal when the running engine (not shown) is stopped.

Next, the operation of the vehicle deodorizing device of the first embodiment thus constructed will be described with reference to the flowchart of FIG. First, the selection mode of the changeover switch 43 is judged based on the selection signal corresponding to each mode (step 1), and when the changeover position of the changeover switch 43 is the deodorizing mode, the parking brake operation detection switch It is determined whether the detection signal is on. When this determination is YES and the parking brake is operating, it is determined in the following step 3 whether or not the traveling engine stop detection switch 45 is on,
If this determination is NO, and if the determination in step 2 is NO, then the procedure returns to the determination in step 1.

If the determination in step 3 is YES, the parking brake is in the operating state, and the traveling engine is also stopped, it is considered that there is no passenger in the passenger compartment 3 and the vehicle is in a safe state. In the next step 4, the operation control means is selected in the deodorizing mode. Therefore, the operation control means turns on the power of the ozone generator 10, turns on the power of the air conditioner to operate the cooling device 5 or the heating device 7 in the internal air circulation mode, and keeps the ventilation device 9 off. .

In the following step 5, the elapsed time t from when the operation control means is selected to the deodorizing mode is 5 minutes to 5 minutes in advance.
It is determined based on the output signal of the timer whether or not it coincides with the time t ₁ set within the range of 10 minutes. If NO, the elapsed time t is continuously measured in step 6. When the elapsed time t matches the set time t ₁ , the deodorizing mode completion display lamp arranged on the instrument panel (not shown) is turned on and the operation control in the deodorizing mode is finished (step 7).

That is, when the changeover switch 43 is switched to the selected position of the deodorizing mode and the parking brake is in the operating state and the running engine is also stopped, the set time t ₁ elapses. During this period, the ozone generator 10 is activated, and the cooling device 5 or the heating device 7 of the air conditioner is operated.
Operates in the inside air circulation mode, ozone gas is generated in the vehicle interior 3, and the air in the vehicle interior 3 containing the ozone gas circulates in the vehicle interior 3.

Here, when the cooling device 5 of the air conditioner operates in the inside air circulation mode, as shown in FIG. 13, the air in the passenger compartment 3 containing ozone gas is supplied to the inside air intake port ( Inside air introduction port (not shown) opened from the baggage compartment / machine room 4, the base end collecting portion of the outside air introduction duct 11,
The air is blown out from a large number of the cold air outlets in a wide range in the vehicle interior 3 through the paths of the inlet 6a of the cooling unit 6, the outlet 6b of the cooling unit 6, the rising duct 12, and the cold air outlet duct 15, thus A wide range within 3 is efficiently deodorized by ozone gas.

When the heating device 7 of the air conditioner operates in the inside air circulation mode, as shown in FIG. 14, the inside air introducing port 16 in which the air containing ozone gas inside the vehicle compartment 3 opens on the floor 2 is provided. From rising duct 17, inlet 8a of heating unit 8, outlet 8b of heating unit 8, rising duct 1
8. The warm air blowing duct 20 blows the warm air from the many warm air outlets 19 into the passenger compartment 3, so that the wide area in the passenger compartment 3 is efficiently deodorized by ozone gas.

When the deodorizing work inside the passenger compartment 3 is completed, the deodorizing mode completion display lamp lights up, and in response to this, the changeover switch 4
When 3 is operated to the switching position of the residual ozone discharge mode,
In step 1, the residual ozone discharge mode is determined. Then, the operation control means turns off the power of the ozone generator 10 to stop its operation, operates the cooling device 5 or the heating device 7 of the air conditioner in the outside air introduction mode, and turns on the power of the ventilation device 9 to turn it on. Operate in the internal air discharge mode (step 8).

In the following step 9, it is determined whether or not the elapsed time t from the time when the operation control means is selected to the residual ozone discharge mode matches the preset time t ₂ in the range of 5 minutes to 10 minutes. Is determined based on the output signal of No., and in the case of NO, the measurement of the elapsed time t is continued in step 10. When the elapsed time t coincides with the time setting t _2, and turns on the discharge mode completion display lamp disposed in an instrument panel (not shown) to end the operation control of the residual ozone discharge mode (step 11).

That is, when the selector switch 43 is switched to the selected position of the residual ozone discharge mode, the ozone generator 10 is switched.
Until the set time t ₂ elapses, the cooling device 5 or the heating device 7 of the air conditioner operates in the outside air introduction mode and the ventilation device 9 operates in the inside air discharge mode. Therefore, fresh air outside the vehicle is introduced into the passenger compartment 3 by the cooling device 5 or the heating device 7, and the air in the passenger compartment 3 containing residual ozone gas is forcibly discharged outside the vehicle by the ventilation device 9. Thus, the safety and comfort of passengers in the vehicle interior 3 after deodorization are ensured. The ozone gas emitted outside the vehicle has a concentration of 0.2 pp as described above.
Since it is extremely low, about m, and is very small, and decays and disappears in a short time, there is no particular problem of air pollution.

When the discharge operation of the residual ozone gas in the passenger compartment 3 is completed and the discharge mode completion indicator lamp is turned on and the changeover switch 43 is operated to the stop mode changeover position in response to this, the stop mode is determined in step 1. Is determined. Then, the operation control means releases the power supply of the ozone generator 10 and stops its operation, and releases the interlocking state of the cooling device 5, the heating device 7 and the ventilation device 9 of the air conditioner so that they can be operated independently. This is done (step 12), and the work of deodorizing the inside of the vehicle is thus completed.

Here, the changeover switch 43 in the above-described first embodiment can be changed to an ON / OFF switching main switch, and the deodorization mode completion display lamp and the discharge mode completion display lamp can be omitted. In the vehicle deodorizing device according to the second embodiment, the function of the operation control means for integrally controlling the operations of the cooling device 5, the heating device 7, the ventilation device 9 and the ozone generating device 10 described above follows the flow chart shown in FIG. Will be realized.

The flow chart shown in FIG. 15 is a partial modification of the flow chart shown in FIG. 12. Steps having the same contents are designated by the same reference numerals, and detailed description thereof will be omitted. Is determined to be ON, and if YES, the control of step 2, step 3, step 4, step 5, and step 6 as the deodorizing mode is sequentially executed.

When the result of the determination in step 5 is YES, the control of steps 8, 9, and 10 as the discharge mode is successively executed in succession, and when the result of the determination in step 9 is YES, the mode is the stop mode. The control of step 12 is continuously executed. If the result of the determination in step 21 is NO, the control jumps to step 12 and the stop mode control is executed.

As described above, in the second embodiment, a series of deodorizing work in the passenger compartment 3 consisting of the deodorizing mode, the residual ozone discharging mode and the stopping mode is continuously executed only by turning on the main switch. The operation is extremely simple and it is possible to prevent operation mistakes.

In FIGS. 12 and 15 showing the control flows of the first and second embodiments described above, the control of steps 2 and 3 may be omitted. In that case, after confirming that there is no passenger in the passenger compartment 3, the changeover switch 43 is operated to the deodorization mode changeover position or the main switch is turned on.

12 and 13 showing the control flow of the first and second embodiments, the control of step 8 in the residual ozone discharge mode is performed by turning off the power of the ozone generator 10. Stop and cool the air conditioner 5
Alternatively, the control may be changed to only operate the heating device 7 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. The fresh air outside the vehicle is introduced into the passenger compartment 3 by operating in the outside air introduction mode, and the air in the passenger compartment 3 containing residual ozone gas is cooled by the cooling device 5 or the heating device 7.
By this, the air is diluted with the fresh air introduced into the passenger compartment 3 and discharged to the outside of the vehicle, thus ensuring the safety and comfort of passengers in the passenger compartment 3 after deodorization.

Further, in FIGS. 12 and 15 showing the control flows of the first and second embodiments, the control of step 4 in the deodorizing mode is performed by turning on the power of the ozone generator 10 and operating it. In addition, the ventilation device 9 is changed to control only to operate in the outside air introduction mode, and in the control of step 8 in the residual ozone discharge mode, the power of the ozone generator 10 is turned off to stop the operation, and the ventilation device 9 is turned off. The control may be changed to only operate in the inside air discharge mode.

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

As described above, according to the first aspect of the 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 internal air circulation mode. As a result, ozone is generated in the vehicle compartment, and the air in the vehicle compartment containing the ozone circulates in the vehicle compartment, so that the vehicle interior can be efficiently and easily deodorized over a wide range.

Further, when the residual ozone discharge mode is selected by the switch means, the operation control means stops the operation of the ozone generator, operates the air conditioner in the outside air introduction mode, and operates the ventilation device, whereby the vehicle is operated. Fresh air outside the vehicle is introduced into the room, and the air inside the vehicle containing residual ozone is forcibly discharged to the outside of the vehicle, ensuring sufficient safety and comfort for passengers inside the vehicle after deodorization. be able to.

According to the second 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 internal air circulation mode. Ozone is generated in the vehicle, and the air containing the ozone in the vehicle is circulated in the vehicle, so that the vehicle can be easily and efficiently 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 operates the air conditioner in the outside air introduction mode, so that the inside of the vehicle is fresh outside the vehicle. Air is introduced and the air in the vehicle compartment containing residual ozone is discharged to the outside of 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 third 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 ventilator in the outside air introduction mode. Ozone is generated in the room, and this ozone is sent to each part inside the vehicle together with the air outside the vehicle introduced by the ventilation device, so that the vehicle interior can be easily and efficiently 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 operates the ventilator in the internal air discharge mode, so that the interior of the passenger compartment containing the residual ozone. Since the air is forcibly discharged to the outside of the vehicle, it is possible to sufficiently ensure the safety and comfort of passengers inside the vehicle after deodorization.

According to the fourth aspect of the invention, even if the deodorizing mode is selected by the switch means, the deodorizing mode is not selected when the parking brake is not in the operating state or the running engine is not in the stopped state. Therefore, it is highly possible that the deodorization mode is mistakenly selected when the passenger is running the vehicle in the vehicle compartment or is temporarily stopped, and the situation that ozone is generated in the vehicle compartment is avoided in advance.
High safety can be secured.

According to the fifth aspect of the present invention, when the deodorizing mode is selected by the switch means, the timer successively selects the residual ozone discharge mode and the stop mode in succession to the selection, so that a series of deodorizing work is continued. Operation is extremely simple.
