(Embodiment 1) A first embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

Generally, a ventilation device installed in a room is required to start operation and dry at the same time when the humidity increases.
Further, it is desirable to stop the operation immediately after finishing the drying. Therefore, the microcomputer 3 is provided so as to receive a signal from the humidity detection circuit 2 which detects the input of the humidity detection element 1 whose conductivity characteristic changes in response to humidity. When the detection element 1 detects a humidity increase of a predetermined value or more (about 1% or more per minute) and then becomes stable (10
The humidity at the time of being stable (when there is no change of 1% or more per minute) is stored in the microcomputer 3 as the reference humidity, and the operation of the motor 6 is started through the drive circuit 5. Also,
The microcomputer 3 calculates the saturated humidity and the reference humidity when the detected humidity is lowered and stabilized by operating the ventilation device by the remaining delay operation time determining means 7 (when there is no change of 1% or more per 10 minutes). The remaining delay operation time is determined according to the difference and the time from the start of operation to the detection of saturated humidity. After that, the microcomputer 3 stops the operation of the motor 6 through the drive circuit 5 after the remaining delay operation time ends by the operation stopping means 8.

Next, the operation of the automatic operation device for the ventilation device having the above construction will be described with reference to FIG. First, step 2
At 1, the humidity "RH" is input from the humidity detection circuit 2 to the microcomputer 3. If the motor 6 is stopped in step 22, it is confirmed in step 23 that the humidity increase above the predetermined value (about 1% or more per minute) has already been detected, and the humidity increase above the predetermined value has already been detected. If not detected, it is confirmed in step 24 that a humidity increase of a predetermined value or more (about 1% or more per minute) is detected. When the humidity increase above the predetermined value is detected, it is stored in step 25 that the humidity increase above the predetermined value is already detected. When the humidity increase above the predetermined value is already detected in step 23, and the humidity is stable in step 26 (when there is no change of 1% or more per 10 minutes), the motor 6 is operated in step 27, and in step 28. The stable humidity "RHo" when stable is stored.

When the motor 6 is operating in step 22, the humidity is stabilized in step 29 (1 per 10 minutes).
% When there is no change) or more.
If it is not stable, the unstable humidity time "T" is measured in step 30. If the humidity is stable in step 29, it is determined in step 31 whether or not the remaining operation is being performed. When the remaining operation is in progress, it is determined in step 32 whether the remaining operation time has ended, and when the remaining operation time has ended, the motor 6 is stopped in step 33. Step 3
If the operation is not in the residual operation in step 1, the saturated humidity "RHb" at that time is stored in step 34. After that, the routine proceeds to step 35, where the stable humidity "RHo" and the saturated humidity "RHb" are used.
The remaining time is determined based on the relationship between the difference between the above and the unstable humidity time “T”.

The steps following steps 25, 28, 30, 33, 35 and steps 24, 32 for NO are:
Both are step 21.

As described above, according to the embodiment, the ventilator is operated immediately when the humidity rises above a predetermined value in the vicinity of the ventilator, and the stable humidity at the start of operation and the saturated humidity during operation are The remaining time is determined according to the difference and the time from the stable humidity to the saturated humidity, and the ventilation system can be automatically started and stopped appropriately.

In the embodiment, the predetermined value serving as a criterion for determining the start, stop, or remaining operation time of the ventilation device is not limited to that of the embodiment, and the user's sense is not limited. It goes without saying that other settings can be made with.

(Second Embodiment) A second embodiment of the present invention will be described below with reference to FIGS. 3 and 4.

By the way, the ventilation device installed in the room is
It is desirable that the operation be started and dried at the same time when the humidity becomes high, and that the operation be stopped immediately after the completion of the drying. Therefore, a humidity detecting circuit 52 for detecting an input of the humidity detecting element 51 whose conductive characteristic changes in response to humidity.
Is provided so that the microcomputer 53 receives a signal from the microcomputer 53. In the microcomputer 53, the operation starting means 54 detects that the humidity detecting element 51 has increased the humidity by a predetermined value or more (about 1% or more per minute), and thereafter. When stable (when there is no change of 1% or more per 10 minutes)
The stable humidity is stored in the microcomputer 53 as the reference humidity, and the driving of the motor 56 is started through the drive circuit 55. Further, the microcomputer 53 operates the ventilator by the residual delay operation time determining means 57 based on the fuzzy reasoning to decrease the detected humidity and stabilize it (when there is no change of 1% or more per 10 minutes). The remaining delay operation time is determined according to the difference between the reference humidity and the reference humidity, and the time from the start of operation to the detection of saturated humidity.

After that, the microcomputer 53 causes the operation stopping means 58 to stop the operation of the motor 56 through the drive circuit 55 after the remaining delayed operation time based on the fuzzy inference basis ends. Next, the operation of the automatic operation device of the ventilation device having the above configuration will be described with reference to FIG. First, in step 71, the humidity “RH” is input from the humidity detection circuit 52 to the microcomputer 53. If the motor 56 is stopped in step 72, the humidity has already risen above the predetermined value in step 73 (more than about 1% per minute).
Is detected, and when the humidity increase above the predetermined value is not already detected, it is confirmed in step 74 that the humidity increase above the predetermined value (about 1% or more per minute) is detected. When the humidity increase above the predetermined value is detected, it is stored in step 75 that the humidity increase above the predetermined value is already detected. When the humidity rise above the predetermined value is already detected in step 73 and the humidity stabilizes in step 76 (when there is no change of 1% or more per 10 minutes), the motor 56 is operated in step 77 and the step 78 is executed. The stable humidity "RHo" when stable is stored.
When the motor 56 is operating in step 72, it is determined in step 79 whether the humidity is stable (when there is no change of 1% or more per 10 minutes). If it is not stable, the unstable humidity time "T" is measured at step 80. If the humidity is stable in step 79,
In step 81, it is determined whether or not the residual operation is being performed by the fuzzy inference base.

During the remaining operation by the fuzzy inference base, it is judged in step 82 whether or not the remaining operating time by the fuzzy inference base has ended. When the remaining operation time by the fuzzy inference base ends, the motor 56 is stopped in step 83. Let When it is determined in step 81 that the remaining operation is not performed by the fuzzy inference base, the saturated humidity "RHb" at that time is stored in step 84. Then proceed to step 85,
The remaining time is determined by a fuzzy inference basis based on the relationship between the difference between the stable humidity “RHo” and the saturated humidity “RHb” and the unstable humidity time “T”. Steps 75, 78, 80, 8
The next stage of steps 3 and 85 and the next stage in the case of NO in steps 74 and 82 are both step 71. As described above, according to the embodiment, when the humidity increase of a predetermined value or more occurs near the ventilation device, the ventilation device is immediately operated, and the difference between the stable humidity at the start of operation and the saturated humidity during operation,
The fuzzy reasoning base determines the remaining time according to the time from the stable humidity to the saturated humidity, and the ventilator can be automatically started and stopped appropriately, and the remaining delay with respect to the humidity of the atmosphere based on the user's feeling. The operating time can be set.

In the embodiment, the predetermined value serving as a criterion for determining the start, stop, or remaining operation time of the ventilation device is not limited to that of the embodiment, and the user's feeling is not limited. It goes without saying that other settings can be made with.

[0022]

As is apparent from the above description of the embodiments, according to the present invention, the operation of the ventilator is promptly started when the high humidity is stable, and the humidity is dried by the operation of the ventilator. Since the difference between the saturated humidity at the time of operation and the stable humidity at the start of operation and the time from the detection of high humidity stability to the detection of saturated humidity stability, the remaining operation time can be determined and the ventilation device can be stopped. Since the remaining operation time can be determined according to the ventilation capacity of the ventilation device, the atmospheric humidity, and the indoor capacity, it is possible to provide an automatic operation device for the ventilation device that can perform appropriate ventilation without operating loss.

Further, since the remaining delay operation time is determined based on the fuzzy inference basis, the operation time can be set in accordance with the humidity of the atmosphere based on the user's feeling, and the ventilation can provide comfortable ventilation. An automatic driving device of the device can be provided.
