DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for a dehumidifier provided with refrigeration means.

[0002]

2. Description of the Related Art In recent years, there has been a great interest in the problem of propagation and the problem of mold that occurs due to the influence of humidity in a house.
See JP-A-59-187817).

[0003] A control device for a conventional dehumidifier will be described below. As shown in FIG. 5, a suction grill 1 made of synthetic resin.
Inside the dehumidifier main body 4 having an outer shell constituted by the outer box 2 and the outlet grill 3, a refrigerating means including a compressor 5, a condenser 6, a capillary tube 7, an evaporator 8, and a blower 10 driven by a motor 9; A drain tank 1 in which dehumidified water generated by an evaporator 8 is dropped and stored from a drain port 12 of a water receiving tray 11.
3 are provided.

[0004] A controller (not shown) of the dehumidifier stops the operation of the compressor 5 when the humidity of the room detected by the humidity sensor falls below a predetermined value, performs only the air blowing by the blower 10, and controls the humidity of the room. When the pressure exceeds a predetermined value, the operation of the compressor 5 is restarted to dehumidify. That is, as shown in FIG. 6, based on the characteristic value of the humidity sensor, the arrow A
The compressor 5 is turned off when the humidity of the room becomes 54% or less, and the compressor 5 is turned on when the humidity becomes 61% or more, and the humidity of the room is controlled to about 60% considered to be appropriate. I was

[0005]

However, in the above-described conventional configuration, since the humidity setting value is determined from the beginning in a configuration in which one point is controlled, the humidity in the room is reduced to 60%.
%, It is impossible to respond to use demands such as when it is desired to keep the dehumidification range, and the dehumidification range is limited, and the humidity set value cannot be arbitrarily selected.

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a control device for a dehumidifier capable of arbitrarily selecting a desired humidity value corresponding to a use.

[0007]

In order to achieve this object, a control device for a dehumidifier according to the present invention comprises: a humidity detecting means for detecting the humidity in a room; a humidity setting means for changing a humidity set value in steps; and signal output means operating or stopping of the compressor of the refrigeration unit in response to the output signal of the comparison means, the humidity detection
First operation input that ignores the signal of the means and instructs continuous operation
Based on the humidity detected by the cutting means and the humidity detecting means.
Operation configured by the second operation on / off means for instructing the operation
This is provided with a turning-in / off means .

[0008]

In this configuration, since the humidity set value can be switched, the humidity can be controlled over a wide range according to the use request.

【Example】

(Embodiment 1) An embodiment of the present invention will be described below with reference to the drawings.

In one embodiment of the present invention, the same components as those of the above-described conventional example are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIG. 1, the control unit 14 includes an input circuit 18 for determining three inputs of an operation stop switch 15, a first switch 16 and a second switch 17, and an input circuit 18 and a humidity sensor 19. A determination circuit 20 for determining an operation mode in response to a detection signal; a humidity setting circuit 22 for setting a humidity value in response to an input from a humidity setting means 21 for switching a humidity setting stepwise; a determination circuit 20 and a humidity setting circuit 2
2, an output relay circuit 23 for driving the compressor 5 and the blower 10 upon receiving the output of the compressor 2 is provided.

The operation of the control device for a dehumidifier configured as described above will be described below.

When the first switch 16 is selected after the operation stop switch 15 is turned on and the power is input, the determination circuit 20 ignores the detection signal of the humidity sensor 19 and determines the continuous operation and outputs the signal. A command to drive the compressor 5 and the blower 10 is output to the relay circuit 23.

When the second switch 17 is selected, the judging circuit 20 determines the humidity of the room based on the detection signal of the humidity sensor 19 (see FIG. 2, for example). 40%, 50% or 6 as shown
When the temperature falls below 0%, the compressor 5 is stopped and only the blower 10 is driven. When the detection signal of the humidity sensor 19 exceeds the humidity value set in the humidity setting circuit 22 due to the stoppage of the operation of the compressor 5, the compressor 5
Is restarted to perform the dehumidifying action.

As described above, according to the present embodiment, since the humidity set value can be switched stepwise, the humidity set value can be changed over a wide range other than the one-point humidity value which has been set as an appropriate humidity. Can use a dehumidifier.

(Embodiment 2) Hereinafter, a second embodiment of the present invention will be described.

As shown in FIG. 3, the present embodiment is characterized in that a storage circuit 24 for storing a prior humidity value set by the humidity setting circuit 22 is added to the configuration of the first embodiment. is there.

According to this configuration, when the first switch 16 is selected, the operation is the same as that of the first embodiment. However, when the second switch 17 is selected, unless the operation stop switch 15 is turned off, The humidity set value becomes the immediately preceding humidity set value, and when the continuous operation is performed without changing the humidity set value in a certain place, once the humidity is set to the desired use once, the humidity setting means 21 is not switched every time the operation is turned off. Even if the user forgets to set the humidity, the operation is automatically performed at the immediately preceding humidity set value, so that the room humidity can be prevented from becoming other than the humidity set value.

Embodiment 3 Hereinafter, a third embodiment of the present invention will be described.

As shown in FIG. 4, the feature of this embodiment is that an automatic setting circuit 25 configured to operate from the lowest humidity setting value is added to the configuration of the second embodiment.

With this configuration, when the operation is performed again after the operation stop switch 15 is turned off, if the humidity setting value of the immediately preceding operation is not stored in the storage circuit 24, the humidity setting value becomes the lowest. Since the automatic setting circuit 25 is provided as described above, the operation start from the high humidity setting can be prevented, the safety and discomfort in the operation space can be reduced, and the environment under conditions unsuitable for high humidity can be eliminated.

[0022]

As is apparent from the above description, the present invention provides a humidity detecting means for detecting the humidity in a room, a humidity setting means for switching a humidity set value in a stepwise manner, and a humidity detecting means in accordance with an output signal of a comparing means. A signal output means for operating or stopping the compressor of the refrigerating means and a signal from the humidity detecting means are ignored, and
First operation on / off means for instructing the vehicle to turn over and the humidity detecting means
Second operation for instructing operation based on the humidity detected by the step
With the configuration provided with the operation on / off means constituted by the on / off means , the desired humidity value corresponding to the application can be arbitrarily selected , and further, the first and second operation on / off means
It is possible to realize an excellent dehumidifier control device that enables a wider range of dehumidification operation .
