BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to FIGS.
[0008]
FIG. 1 shows a combination of a cooler unit such as a freezing van or an insulated van and an ozone generator, and FIG. 2 shows a portion of a vehicle equipped with a sanitary maintenance device based on the combination of the cooler unit and the ozone generator of FIG. FIG. 3 is a cross-sectional view, and FIG. 3 is a flowchart of an ozone generation control routine.
[0009]
First, the configuration and functions of the entire apparatus will be described with reference to FIGS. As shown in FIG. 1, 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 an inside / outside air A fan 8 for pumping the intake air sucked from the switching valve 6 to a cooler body 7 having a dehumidifying function, a discharge port 9 for discharging cool air from the cooler body 7 to the luggage compartment 21 of FIG. 2, a cooler operation switch 10, and an ozone generator. A cooler unit 14 including a switch 11, a door opening / closing switch 12 linked to opening / closing of the rear door 1, and a control unit 13 for controlling the cooling and the generation of ozone in the cargo room by a signal from these switches is mounted. I have.
[0010]
An ozone generator 3 for generating ozone by applying a high voltage is interposed between the cooler body 7 and the discharge port 9.
[0011]
In FIG. 1, symbols N1, N2, and N3 are input signal lines, and symbols C1, C2, C3, and C4 are output signal lines.
[0012]
Here, it is known that ozone is easily generated in dry air, and is generated at a high rate when a cooler is operated with a dehumidifying function. In addition, since ozone has a sterilizing action and a deodorizing action, it can sterilize and deodorize the cargo room itself and the cargo.
[0013]
Next, a method of controlling the deodorizing / sterilizing function of the cargo room and the cargo, that is, a method of controlling the ozone generating function will be described with reference to FIGS.
[0014]
After starting, it is determined whether or not the ozone generation switch 11 is to be operated (step S1, which is described as S1 in the figure, the same applies hereinafter), and if the operation is not desired (NO in step S1), the control is ended. If the user wants to operate (YES in step S1), the control unit 13 determines whether the door 1 is closed by operating or not operating the door open / close switch 12 (step S2), and if the door 1 is not closed (step S2). In step S2, the control ends. If the door 1 is closed (YES in step S2), the inside / outside air switching valve 6 is introduced into outside air (step S3), the cooler operation switch 10 is turned on (step S4), and the fan 8 is operated (step S4). Step S5).
[0015]
Next, proceeding to step S6, the ozone generator 3 automatically operates. Then, the time elapses, and the control unit 13 (having a timer function) determines whether or not the timer has elapsed a predetermined time (step S7). If the predetermined time has not elapsed (step S7). (NO), the process proceeds to step S11.
[0016]
If the predetermined time has elapsed (YES in step S7), the ozone generator 3 is turned off (step S8), and the control unit 13 determines whether the predetermined time has elapsed since the ozone generator 3 was turned off. (Step S9), and if the predetermined time has not elapsed (NO in Step S9), the processing is continued until the predetermined time has elapsed.
[0017]
If the predetermined time has elapsed (YES in step S9), the control unit 13 determines whether or not the ozone generation switch 11 is OFF (step S10). In (NO in step S), the control returns to step S6. If the ozone generation switch 11 is off (YES in step S10), the process proceeds to step S13, and the operation of the ozone generation device 3 is stopped.
[0018]
The flow returns to step S11 (NO in step S7), and control unit 13 detects whether or not door 1 is closed based on information of door open / close switch 12 that detects opening and closing of door 1 at the rear of loading platform 2. . If the door 1 is not closed (NO in step S11), the control proceeds to S13, where the operation of the ozone generator 3 is stopped.
[0019]
If the door 1 is closed (YES in step S11), 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 (in step S12). (NO), the control returns to S7. If the ozone generation switch 11 is in the OFF state, the operation of the ozone generation device 3 is stopped (step S13).
[0020]
Next, the control unit 13 determines whether or not the cooler main body 7 is operating (step S14), and if the cooler main body 7 is operating (NO in step S14), the control is switched to the control on the cooler side. .
[0021]
If 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.
[0022]
Next, an ozone generation control flow of another embodiment will be described with reference to FIG.
[0023]
In FIG. 4, instead of the operation of the cooler 7 in step S4 in FIG. 3, it is determined whether or not the vehicle is in the loaded state (step S41). If the vehicle is in the loaded state (YES in step S41), the cooler is dehumidified. Only the function is activated (step S42), and if the vehicle is not in the loaded state (NO in step S41), the cooler 7 is activated (step S43), and the process proceeds to the next step S5 in FIG. The same control as in No. 3 is used.
[0024]
【The invention's effect】
According to the present invention having the above structure, ozone is easily generated in air in a dry state, and therefore, can be generated at a high rate when a cooler is operated with a dehumidifying function. Since it has a deodorizing effect, it is possible to automatically sterilize and deodorize the cargo room and the cargo of the vehicle when the cooler is activated.
