(Operation) The operation of the apparatus having the above configuration will be described below.

When the input power supply section of this device is connected to the commercial power supply, the commercial power supply supplies power to the output power supply sections via the input power supply section and the switch elements.At this time, the humidity detected by the humidity sensor is detected. Based on the above, the drive control unit drives or disconnects the plurality of switch elements, respectively.

As a result, one of the plurality of switch elements connects the input power supply section and the corresponding output power supply section, and the other switch element sets the input power supply section and the corresponding output power supply section in a non-connected state.

By the above operation, one of the plurality of output power supply units is in the power supply state and the other output power supply unit is in the power cutoff state. Further, by operating the short-circuit switch, each of the switch elements is short-circuited, and power is always supplied to the output power source section regardless of the driving state of each of the switch elements.

(Embodiment) An embodiment of the present invention will be described in detail below.

The humidity control power supply device 1 shown in FIG. 1 has a box-shaped device body 2, and an input plug connectable to a commercial power supply (AC100V or AV200V) on one end side of the device body 2. 3 and an input power supply section 5 comprising an input cord 4 connected to the input plug 3.

The drive control unit 12 includes a charging power source 16 connected to the input cord 4, the humidity setting unit 10, and the humidity sensor 9
Of the first set of the drive signal corresponding to this set humidity based on the set humidity set by the humidity setting section 10.
The first amplifier 17 for sending to the switch element and the inverter 18 for inverting and sending the detection signal of the humidity sensor 9.
The output signal of the inverter 18 and the humidity set by the humidity setting unit 10 are taken in, and the first amplifier 18
In the case of (2), a second amplifier 19 for sending a drive signal inverted to the set humidity as a boundary to the second switch element 14 is provided.

In FIG. 2, 20 is a heater connected to the charging power source 16 to refresh the humidity sensor 9.

Next, referring to FIG. 3 (a),
The description will be made also with reference to (b).

In the following description, it is assumed that a humidifier is connected to the first outlet 6 and a dehumidifier is connected to the second outlet 7 in the initial state.

In this state, the input outlet 3 is connected to a commercial power source of AC100 (V), and the humidity setting unit 10 sets the humidity of 60%.

The electric power from the commercial power source is about to be supplied to the humidifier and the dehumidifier via the first and second outlets 6 and 7, respectively. At this time, the humidity detected by the humidity sensor 9 and the setting by the humidity setting unit 10 are performed. The first amplifier 17 which takes in the humidity continues to send the drive signal to the first switch element 13 until the humidity reaches 60%.

On the other hand, the second amplifier 19 which takes in the detected humidity from the humidity sensor 9 by inverting it by the inverter 18 does not send the drive signal to the second switch element until the humidity reaches 60%.

As a result, the first switch element 13 is turned on, the second switch element 14 is turned off, the humidifier is in the energized state, and the dehumidifier is in the dehumidifier as shown in FIGS. 3 (a) and 3 (b). The de-energized state is set and the humidification is performed only by the humidifier.

Eventually, when the atmospheric humidity reaches 60%, the first amplifier
The drive signal from 17 to the first switch element 13 is cut off, and the second amplifier 19 sends a drive signal inverted from that of the first amplifier 19 to the second switch element 14.

As a result, the first switch element 13 is turned off and the second switch element 14 is turned on, the power supply from the first outlet 6 to the humidifier is cut off, and the second outlet 7 is turned off.
The electricity to the dehumidifier starts from.

Therefore, in this case, only the dehumidifying operation by the dehumidifier is performed.

If the operation piece 11 of the changeover switch 15 is operated to short-circuit the first and second switch elements 13 and 14, respectively, regardless of the operation of the humidity sensor 9, the input outlet 5 can be connected to the first and second switch elements.
Electric power can be directly transmitted to the respective outlets 6 and 7. Therefore, it is suitable for supplying power to a device unrelated to humidity detection.

FIG. 4 shows another example of the embodiment of the present invention. In the power supply device with humidity control 1A shown in the same figure, instead of the input outlet 3 and the input cord 4, a direct attachment type input outlet 3A is provided. The difference from the device 1 shown in FIG. 1 is that it is attached to the device body 2.

This device 1A can also exhibit the same operation as the above case.

The present invention is not limited to the above embodiment,
Various modifications are possible within the scope of the gist.

For example, the number of output outlets is not only the above two,
The same operation can be performed with any number such as three or four.

Needless to say, the humidity set by the humidity setting unit 10 can be set to a desired value other than the above-mentioned 60%.

[Advantages of the Invention] According to the present invention described in detail above, with the above configuration, it is possible to perform an operation with humidity control by connecting a humidifier or a dehumidifier without a humidity sensor, which is comfortable. It is possible to provide a power supply device with humidity control that can contribute to environment creation. Further, since the short-circuit switch is provided, it has an advantage that it can be used for supplying power to a device unrelated to humidity detection by operating the short-circuit switch.
