[0014]
Next, a block diagram of the control circuit will be described with reference to FIG.
A control unit 25 controls the entire device. Based on a program stored in the storage unit in advance, a power switch 26, an operation switch 27, a timer switch 28, a timer switch 28 provided in an operation unit (not shown) of the housing 1 are provided. Energization of the air pump 2, the blower 8, the electromagnetic valves 19, 20, 21, the heater 24, the damper motor 31, the display unit 32, and the like is controlled by input operations of the mode switch 29, the alarm switch 30, and the like.
[0015]
Next, the operation of the ozone fumigation deodorizer shown in the first embodiment will be described.
First, the operation | movement at the time of an ozone generation driving | operation is demonstrated according to FIG.
When the operation switch 27 is turned on while the power switch 26 is on, the ozone generation operation is started, and the damper motor 31 that drives the blower 8, the ozone generator 4, the air pump 2, the electromagnetic valve A19, the electromagnetic valve B20, and the damper 13 is started. Each is energized. The solenoid valve A19 and the solenoid valve B20 are opened by energization, and when the damper 13 reaches the position shown in FIG. 1 by driving the damper motor 31, the control unit 25 automatically stops energization to the damper motor 31. Hold.
[0016]
The raw material air taken in from the vent hole 33 by driving the air pump 2 enters the dryer 3 through the connection pipe 16 through the electromagnetic valve A19, and after moisture is removed by the moisture absorbent 22, passes through the electromagnetic valve B20. It is introduced into the ozone generator 4 through the connecting pipe 17, converted into ozone, and discharged from the ozone discharge pipe 5 into the mixing chamber 14.
On the other hand, the air taken in from the first air intake 6a through the pre-filter 10 by driving the blower 8 is mixed with the ozone in the mixing chamber 14, and then passes through the blower 8 and passes through the blower outlet 9. It is blown out more indoors. This operation is performed for a predetermined time set by the timer switch 28 and the mode change switch 29 to perform deodorizing treatment in the room.
[0017]
When the deodorizing process is completed, the operation is switched to the ozonolysis operation. The operation during the ozonolysis operation will be described with reference to FIG.
During the ozonolysis operation, the damper motor 31 is energized by the controller 25, and the damper 13 is switched to close the first air intake 6a and open the second air intake 6b. , Energization of the solenoid valve B20 is stopped. As a result, the electromagnetic valve B20 is closed, and the ozone generation in the ozone generator 4 is stopped.
On the other hand, energization of the heater 24 and the electromagnetic valve C21 is started, the electromagnetic valve A19 and the electromagnetic valve C21 are opened, and the drying and regeneration operation of the moisture absorbent material 22 is started in parallel with the ozone decomposition operation.
[0018]
First, the ozone decomposition operation will be described. Residual ozone in the room is taken into the decomposition passage 12 from the second air intake 6 b through the prefilter 10 and the ozone decomposition filter 7 by driving the blower 9. At this time, it comes into contact with the ozone decomposing filter 7, is decomposed into enzymes and the like, and is blown out from the decomposing passage 12 through the mixing chamber 14 and blown out from the outlet 9, whereby the residual ozone in the room is decomposed.
[0019]
Next, the drying and regeneration operation of the hygroscopic material 22 performed in parallel with the ozonolysis operation will be described. The dryer 3 is heated by energization of the heater 24, and this heat is transmitted to the radiating fins 23. On the other hand, the hygroscopic material 22 is efficiently heated by being conducted from both the inner wall of the dryer 3 and the surface of the radiation fins 23. When heated, the moisture contained in the hygroscopic material 22 evaporates, and this evaporated moisture is sent from the exhaust pipe 18 whose one end is connected to the upper part of the dryer 3 together with the pressurized air by the air pump 2 through the electromagnetic valve C21. The other end of the exhaust pipe 18 is discharged into the decomposition passage 12, and the moisture absorbent material 22 is dried and regenerated.
[0020]
The control unit 25 stops energization of the heater 24 a predetermined time before the end of the drying regeneration operation of the hygroscopic material 22, cools the hygroscopic material 22 with the pressurized air from the air pump 2, and discharges residual heat through the exhaust pipe 18. To do. Thereafter, when the operation end set time is reached, all energization is stopped. Accordingly, the dryer 3 is kept in a sealed state by closing the electromagnetic valve A19, the electromagnetic valve B20, and the electromagnetic valve C21.
As described above, according to the configuration of the first embodiment, the dryer 3 is provided with the heater 24 and the heat radiating fins 23. Therefore, the drying and regeneration operation of the moisture absorbent 22 can be performed efficiently in a short time, and the moisture absorbent 22 The next ozone generation operation can be carried out smoothly because it can be rapidly cooled. Further, since the dryer 3 is kept completely sealed when not in use, the hygroscopic material 22 does not absorb moisture, the replacement work of the hygroscopic material 22 becomes unnecessary, and stable ozone generation can be realized.
[0021]
【The invention's effect】
As described above, according to the ozone fumigation deodorizer according to the present invention, it is possible to efficiently dry and regenerate the moisture absorbent material of the dryer simultaneously with the ozonolysis operation, and to efficiently remove moisture evaporated from the moisture absorbent from the exhaust pipe. effect called can be discharged can be obtained.
[0022]
Further, since the other end of the exhaust pipe is opened in the ozone decomposition passage communicating with the second air intake port , the exhaust pipe can be efficiently discharged from the outlet through the decomposition passage.
