"Problems to be Solved by the Invention" By the way, when trying to dry the inside of the bathroom I, there are many means for generating moisture, such as the bathtub 2, in the bathroom I, and the bathroom 1 is usually not airtight. Therefore, the humidity inside the bathroom I is often higher than the outside humidity. Therefore, if the air dryer 3 is operated in this state, the operating time of the air dryer 3 will be long.
Since the power consumption of the compressor 11 and the like increases, there is a problem in that the electricity bill increases.

The present invention has been made in view of the above-mentioned problems, and its purpose is to provide an indoor drying method in which the operation time of the air dryer is short and the electricity bill can be suppressed as much as possible. It is to provide.

"Means for Solving Problems" The present invention provides an air dryer that dehumidifies and dries indoors, and includes a 15i degree sensor for detecting indoor arcuate degree and a second sensor for detecting outdoor humidity. A humidity sensor and a discharge device for discharging indoor air to the outdoors are provided, and the discharge device is activated only when the indoor humidity is higher than the outdoor humidity when the air dryer starts operating. By an indoor drying method in which the operation is performed before the J turn of the air drying P1 machine,
This solves the above problems.

"Function" According to the present invention, when the indoor humidity is higher than the outdoor humidity, the indoor humidity can be lowered to the outdoor humidity without operating the air dryer.

"Embodiments" Examples of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing an apparatus for carrying out a room drying method according to an embodiment of the present invention. In the following description, the same components as those of the conventional device are designated by the same reference numerals, and the description thereof will be omitted.

The difference between the device shown in FIG. 1 and the conventional device shown in FIG. 2 is that a humidity sensor for detecting the humidity outside the bathroom;
and a discharge device for discharging the air inside the bathroom 1 to the outside of the bathroom 1.

That is, the air passage 4 is provided with an exhaust communication passage 20, and one open end thereof is located between the blower 7 and the air outlet IO.

A connection port 16 is attached to the other open end of this communication path 20, and one end of this connection port I6 is connected to a bathroom.
An exhaust duct 17 extending outside is connected, thereby communicating the communication path 20 with the outside of the bathroom I. Further, at one open end of the communication passage 20, a fallable damper 18 having an area approximately equal to the flow passage area of the air passage 4 and an electric damper drive device 19 for driving the damper 18 are provided. . In the above configuration, the blower 7, the communication path 20
, the connection port 16, the exhaust duct 17, the damper I8, and the electric damper drive device 19 constitute a discharge device 25 that discharges the air inside the bathroom I to the outside of the bathroom I.

In addition, the air dryer 3 is installed outside the bathroom I and this bathroom! A humidity sensor 21 (second m degree sensor) is provided to detect outside humidity. The electric damper drive device 19 and the humidity sensor 21 are controlled by the control circuit 14 by transmitting and receiving signals to and from the control circuit I4.

Next, a method for drying a room (bathroom 1), which is an embodiment of the present invention, will be described using the apparatus having the above configuration.

First, as in the prior art, moisture-containing clothing 15 such as laundry is placed in the bathroom I, and the humidity sensor 13.
By 21, the bathroom at this time! Detects the humidity inside and outside the bathroom I. Next, the humidity in Bathroom I is a bathroom! When the humidity is higher than the outside humidity, the electric damper drive device 19 is transmitted from the control circuit 14.
The driving device 19 causes the damper I8 to overturn, thereby closing the air passage 4. At the same time, the blower 7 is started in response to a signal from the control circuit 14 to generate a unidirectional air flow in the air passage 4 as shown in the direction of arrow B in FIG. 9 and discharged to the outside of the bathroom 1 through the communication path 20 and the exhaust duct 17.

During the air exhaust operation in the bathroom 1, the humidity inside the bathroom 1 and outside the bathroom 1 is detected by the humidity sensor 13.21, and the humidity inside the bathroom 1 becomes approximately equal to the humidity outside the bathroom 1. In this state, the air passage 4 is unblocked by the damper 18, the open end of the communication passage 20 is closed by the damper 18, the compressor 11 is started, and the bathroom 1 is opened as in the conventional case. Perform dehumidification and drying work on the air inside.

Further, when the humidity inside the bathroom I is already lower than the humidity outside the bathroom 1 at the time of placing the clothes I5, the air exhaust operation by the exhaust device 25 is omitted, and the operation of the compressor 11 is immediately started. Perform dehumidification and drying work on the air inside.

Then, as in the conventional case, the humidity sensor I3 detects the completion of drying the clothes I5, and when the humidity in the bathroom l falls below the set humidity, the air dryer 3 (compressor 11, blower 7) is turned on. Then, the drying work in the bathroom 1 is completed.

In the room drying method described above, when the air dryer 3 is started, the humidity inside the bathroom I and the humidity outside the bathroom I are detected, and the humidity inside the bathroom I is determined to be the same as the humidity inside the bathroom I. The exhaust device 25 is activated only when the humidity is higher than the outside humidity, and the humid air inside the bathroom is removed from the bathroom.
Since the method is such that the air is discharged outside, even if the humidity inside the bathroom is higher than the humidity outside the bathroom, the compressor 11
The humidity inside the bathroom 1 can be lowered to the humidity outside the bathroom 1 without operating the bathroom 1. Therefore, the operating time of the air dryer 3 as a whole can be shortened, and the power consumption of the compressor 11 required to lower the humidity in the bathroom I to the humidity outside the bathroom 1 can be reduced, and the electricity bill can be reduced. suppressed. Therefore, it is possible to provide a room drying method that requires only a short operating time of the air dryer and can therefore reduce electricity costs as much as possible.

In addition, the air dryer 3 can be used only by discharging the air inside the bathroom 1.
By omitting this operation, the air inside the bathroom 1 can be ventilated.

Note that the room drying method of the present invention is not limited to the above embodiments. - As an example, the discharge device 25 is provided in communication with the air passage 4, but these may be provided separately from each other. In addition, the air dryer 3
The configuration is not limited to the above-mentioned embodiment, and may be appropriately selected from known devices as long as it is a dryer capable of dehumidifying and drying air. Also, this indoor drying method can be used in the bathroom! The present invention is not limited to applications, but can be applied to any room that requires dehumidification and drying, such as living rooms and halls.

"Effects of the Invention" As described in detail above, according to the present invention, the operation of the discharge device is stopped when the air dryer starts operating and the indoor humidity is higher than the outdoor humidity. Since this is performed before the operation of the air dryer, even if the indoor humidity is higher than the outdoor humidity, the indoor humidity can be lowered to the outdoor humidity without operating the air dryer. Therefore, the operating time of the air dryer as a whole is shortened, and the power consumption of the air dryer required to lower the indoor humidity to the outdoor humidity can be reduced, thereby reducing electricity costs.

Therefore, it is possible to provide an indoor drying method in which the operating time of the air dryer is short and the electricity bill can be suppressed as much as possible.
