DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 shows a combination of a cooler unit such as a refrigerating van or a refrigerating van with an ozone generator, and FIG. 2 is equipped with a sanitary maintenance device by a combination of the cooler unit and the ozone generator of FIG. FIG. 3 is a partial transverse sectional view of the vehicle, and FIG. 3 is a flowchart of an ozone generation control routine.

First, the overall structure and function of the apparatus will be described with reference to FIGS. 1 and 2. As shown in FIG. 1, in the upper part of the front surface of the box-type carrier 2 of FIG. 2, an inside air intake port 4, an outside air intake port 5, an inside / outside air switching valve 6 for switching between inside air intake and outside air intake, and the inside / outside air A fan 8 for pumping the intake air sucked from the air switching valve 6 to a cooler body 7 having a dehumidifying function,
A discharge port 9 for discharging cool air from the cooler main body 7 to the luggage compartment 21 of FIG. 2, a cooler operation switch 10, an ozone generation switch 11, a door opening / closing switch 12 that interlocks with the opening and closing of the rear door 1, and these switches. Control unit 1 which controls cooling and ozone generation in the cargo compartment by signals from
A cooler unit 14 composed of 3 and 3 is attached.

An ozone generator 3 for generating ozone by applying a high voltage is interposed between the cooler unit 14 and the discharge port 9.

In FIG. 1, symbols N1, N2 and N3 are input signal lines, and symbols C1, C2, C3 and C4 are output signal lines.

It is known that ozone is likely to be generated in dry air, and for that reason, it is generated at a high rate when the cooler is operated with a dehumidifying function. Further, since ozone has a sterilizing action and a deodorizing action, it is possible to sterilize and deodorize the cargo compartment itself and the cargo.

Next, a method of controlling the deodorizing / sterilizing function of the cargo compartment and the cargo, that is, the method of controlling the ozone generating function will be described with reference to FIGS. 3, 1 and 2.

After starting, it is judged whether or not the ozone generation switch 11 is operated (step S1, S in the figure).
Write 1. The same applies to the following), and if the operation is not desired (NO in step S1), the control ends. When it is desired to operate (YES in step S1), the control unit 13 is operated by operating or not operating the door opening / closing switch 12.
Determines whether the door 1 is closed (step S
2) If the door 1 is not closed (NO in step S2), the control ends. When the door 1 is closed (YES in step S2), the inside / outside air switching valve 6 is introduced into the outside air (step S3), the cooler operation switch 10 is turned on (step S4), and the fan 8 is operated ( Step S5).

Next, in step S6, the ozone generator 3 automatically operates. Then, when the time has passed, the control unit 13 (having a timer function) judges whether the timer has passed a predetermined time (step S7), and when the predetermined time has not passed (in step S7) If NO, the process proceeds to step S11.

When a predetermined time has passed (step S
If YES in 7), the ozone generator 3 is turned off (step S8), and further, the control unit 13 determines whether or not a predetermined time has passed since the ozone generator 3 was turned off (step S9), and the predetermined value is determined. If the time has not passed (NO in step S9), the process is continued until the time passes.

When a predetermined time has passed (step S
9 is YES), the control unit 13 then determines whether or not the ozone generation switch 11 is in the OFF state (step S10), and the ozone generation switch 11 is turned off.
If not in the FF state (NO in step S), the control returns to step S6. If the ozone generation switch 11 is in the OFF state (YES in step S10), the process proceeds to step S13, and the ozone generator 3 stops its operation.

The flow is returned to step S11 (NO in step S7), and the control unit 13
Is a door opening / closing switch 1 that detects opening / closing of the door 1 at the rear of the loading platform 2.
It is detected based on the information of 2 whether the door 1 is closed. When the door 1 is not closed (NO in step S11), the control proceeds to S13, and the operation of the ozone generator 3 is stopped.

If the door 1 is closed (step S
If YES in 11), the control unit 13 determines whether or not the ozone generation switch 11 is in the OFF state, and if the ozone generation switch 11 is not in the OFF state (NO in step S12), the control returns to S7. When the ozone generation switch 11 is off, the operation of the ozone generation device 3 is stopped (step S1).

Next, the control unit 13 determines whether or not the cooler body 7 is in operation (step S
14) If the cooler body 7 is operating (step S1)
In No. 4, NO) control is switched to control on the cooler side.

When the cooler body 7 is not operating (YES in step S14), the fan 8 is stopped (step S15), the inside / outside air switching valve is turned off (step S16), and the control is terminated.

Next, an ozone generation control flow of another embodiment will be described with reference to FIG.

In FIG. 4, instead of the operation of the cooler 7 in step S4 of FIG. 3, it is judged whether or not the vehicle is in a loaded state (step S41), and if it is in a loaded state (YES in step S41). Only the dehumidifying function of the cooler is operated (step S42), if it is not in the loaded state (NO in step S41), the cooler 7 is operated (step S43), and the process proceeds to the next step S5 in FIG. All have the same control as in FIG.
