It is a motor that (14) is an air temperature detection means that detects the temperature of the hot air in the blow-off hole (7) via an air temperature sensor (6).

The triac is connected in series with the triac, and each gate is connected to the output Po1 and the output Po2 of the microcomputer (11) via resistors (21) and (22).

(23) is a numerical display means, which is operated by a microcomputer (1

) is a stop switch that stops the operation, and (27) is a push-lock type futon selection switch that repeats opening and closing each time it is pressed.

The operation of the futon dryer having such a configuration will be explained with reference to the time chart shown in FIG. first,
A bag-like sheet (not shown) having air permeability in the blow-off hole (7)
Attach the sheet and place it between the comforter and mattress to prepare for drying. When the power is turned on at time t0, one of the futon selection display lamps (24c) and (24d) lights up in response to opening and closing of the futon selection switch (27). Here, it is assumed that drying of a cotton futon has been selected and the cotton lamp (24d) is lit. t1
When the start switch (25) is pressed down at this point, the microcomputer (11) lights up the drying process display lamp (24a) according to a preset program and displays "3 hours 00 minutes" blinking on the numerical display means (23). let This display time is the maximum operating time of this dryer, and the blinking indicates that the operating time has not been officially determined yet. At the same time, the triac (19) is turned on and the motor (13) is rotated to start blowing air between the futons.

[0012] Air is blown for a predetermined period of time (6 seconds in this example), and indoor air is taken into the case (1) of the futon dryer.
After the room temperature sensor (8) and humidity sensor (9) have become accustomed to the air in the room where the futon is being dried, the room temperature detection means (15) and humidity detection means (16) detect the temperature and humidity of the room air at time t2. do.

[0013] Based on the detected value, first, the time for the drying process is determined. If the room temperature is low, it is difficult for the hot air temperature to rise and the drying efficiency decreases, so set a longer drying time.
On the other hand, when the room temperature is high, the temperature of the hot air tends to rise and drying is easy, so the drying time is shortened. In addition, if the duvet is selected by the futon selection switch (27),
In this embodiment, the drying time is programmed to be about 20% longer than when cotton comforter is selected. This is because when drying using a duvet as a comforter, warm air easily escapes from the comforter, making it difficult for the mattress to dry, resulting in lower drying efficiency than when drying using a cotton comforter as a comforter. Further, when the humidity is high, the futon is expected to contain a lot of moisture, so the drying time is set longer, and when the humidity is low, the drying time is set shorter. The time for this drying process is set in advance in the microcomputer (11) as shown in FIG. 5, and in this embodiment is incorporated into the program as a data table in the form of output (drying time) for input. Assuming that the output of the room temperature detection means (15) is 13° C. and the output of the humidity detection means (16) is 65% relative humidity, the drying time is determined to be 1 hour and 36 minutes from FIG. And the microcomputer (11)
stores the room temperature of 13°C and humidity of 65% at this time in its internal memory.

Next, based on the output of the room temperature detection means (15), the control details for the finishing process to be performed after the drying process are determined. The microcomputer (11) has a data table showing the relationship between the input (room temperature) (output of the room temperature detection means (15)) and the output (air blowing time, hot air temperature) as shown in Figure 6, just as when setting the drying time. It is included in the program as. Here, since the output of the room temperature detection means (15) is 13°C, the air blowing time in the finishing process is 9 minutes, and the target finishing temperature is 41°C.
℃, and the hot air temperature is set to 43℃.

The microcomputer (11) displays the total value of the drying time and finishing air blowing time "1 hour 45 minutes" on the numerical display means (2).
3) is displayed blinking. The purpose of the blinking display is to indicate that the decision is still tentative. From this time t2, the microcomputer (11) ignites the triac (20) and turns on the heater (5).
), and the air blown out from the blow-off hole (7) becomes warm air.

[0016] Immediately after that, at time t3, when the futon selection switch (27) is operated and the cotton futon is changed to a duvet, the microcomputer (11) turns off the cotton lamp (24d) and turns on the feather lamp (24c). This indicates that the futon selection has been switched, and the room temperature and humidity data stored in the storage means are
The drying time determination process described above is performed again using the drying timer. Here, since the futon selection is down, the drying time is 1 hour 56 minutes based on FIG. 5, and the total time including the finishing time "2 hours 05 minutes" is displayed blinking. This operation is repeated every time the futon selection is changed.

[0017] Predetermined time from t2 (60 seconds in this embodiment)
Later, at time t4, the temperature and humidity of the indoor air are detected again by the room temperature detection means (15) and the humidity detection means (16).
The drying time, the air blowing time during finishing, and the hot air temperature are determined in the same manner as at point 2, and the time obtained by subtracting the 60 seconds from the total time of the drying time and the air blowing time is lit on the numerical display (23). Assuming that the room temperature is detected to be 17°C and the humidity is 67% at time t4, the drying time of the duvet is 1 hour and 46 minutes based on Figure 5, the air blowing time is 12 minutes based on Figure 6, and the hot air temperature is The temperature is determined to be 39° C., and “1 hour and 57 minutes” is displayed on the numerical display (23). Then, the microcomputer (11) stores the room temperature of 17° C. and humidity of 67% at this time in its internal memory instead of the values at time t2. The reason for determining the drying time and finishing time again is that if the temperature and humidity of the air inside the futon dryer and the air in the room are significantly different, the temperature and humidity cannot be detected accurately in the initial 6 seconds. This is because there are things that cannot be done.

The temperature of the warm air during the drying process (t2 to t6) is based on the futon selection settings, and the maximum temperature is 60°C for cotton futons.
When using a duvet, the temperature is set at 50°C, and the microcomputer (11) controls the energization of the heater (5) based on the output of the air temperature detection means (14) so that the hot air temperature does not exceed the temperature. . These temperatures are for safety and to not damage the fibers of the futon. Especially when using duvets, the temperature is kept low to avoid damaging the oils and fats in the feathers (maintaining an appropriate moisture content of 12.5%).

As time passes, the display time of the numerical display means (23) is reduced every minute. At time t5, 10 minutes after time t2, the user realized that he had made a mistake in the futon selection settings, and when he operated the futon selection switch (27) to change from the duvet to the cotton futon, the microcomputer (1
In step 1), the cotton lamp (24d) is turned on again, and the drying time is determined in the same manner as at time t4 using the room temperature of 17° C. and humidity of 67% stored in the memory. As a result, the drying time was 1 hour and 26 minutes, which was 12 minutes longer than the air blowing time.
If you add the minutes, it becomes 1 hour and 38 minutes, but since 10 minutes have passed, 1 hour and 28 minutes is displayed, and the hot air temperature is set to 60°C to continue drying. Here, if the elapsed time since the start of heater power supply exceeds the reselected futon drying time setting, the air blowing time for the finishing process set at time t4 will be displayed on the numerical display (23). The display is turned on, the finishing process is immediately started, and the finishing operation is performed according to the control details determined at time t4.

At time t6, when 1 hour and 26 minutes have passed from time t2 and the drying time has ended, the process display is switched from the drying lamp (24a) to the finishing lamp (24b) to indicate that the finishing process has begun. In the finishing process, hot air is controlled and blown at the temperature determined at time t4. Further time passes, and at time t7 when the remaining time is 5 seconds, the heater (5) is de-energized and only the motor (13) is energized to send cold air. This is to remove the hot air inside the futon dryer so that the initial temperature and humidity can be detected accurately even when it is used continuously. When the finishing process is completed, the finishing lamp (24
b) is turned off and a notification is given by the notification means (17). During the notification, the numerical display means (23) displays "0 minutes". When the notification is completed, the display on the numerical display means (23) is turned off at time t9, and the state returns to the initial state.

[0021] In the above embodiment, an example was shown in which a cotton comforter and a down comforter could be selected, but it is also possible to select between a summer comforter and a winter comforter, which have the same control temperature but different drying efficiency. Can be applied. Further, in this embodiment, a futon selection switch is provided, but separate switches for starting two drying controls, such as a cotton futon drying switch and a feather drying switch, may be provided.

Further, in this embodiment, the drying time was set based on room temperature and humidity, but it is also possible to set the drying time only at room temperature.
