Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dehumidifier control device having a refrigerating means.

[0002]

2. Description of the Related Art In recent years, there has been a great deal of interest in problems such as the problems of growing and the fungi which occur due to the influence of humidity in the house, and proper humidity adjustment has been devised (for example,
See Japanese Utility Model Laid-Open No. 59-187817).

A conventional dehumidifier controller will be described below. As shown in FIG. 5, a synthetic resin suction grill 1
Inside the dehumidifier main body 4 having an outer casing 2 and an outlet grill 3 as an outer shell, a refrigerating unit including a compressor 5, a condenser 6, a capillary tube 7, an evaporator 8 and a blower 10 driven by a motor 9, Drainage tank 1 in which dehumidified water generated by the evaporator 8 is stored by being dripped from the drain port 12 of the water tray 11
And 3 are provided.

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 and only blows air by the blower 10 to obtain the humidity of the room. When the value exceeds a predetermined value, 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
Compressor 5 turns off when the humidity in the room is 54% or less, and compressor 5 turns on when the humidity is 61% or more to control the room humidity to about 60%, which is considered to be appropriate. Was there.

[0005]

However, in the above-described conventional configuration, the humidity set value is fixed from the beginning in the configuration in which the one-point control is performed, so that the room humidity is set to 60%.
However, there is a problem in that it is not possible to meet the demand for use when it is desired to keep the ratio below%, the dehumidifying range is limited, and the humidity set value cannot be arbitrarily selected.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a dehumidifier controller capable of arbitrarily selecting a desired humidity value corresponding to the intended use.

[0007]

In order to achieve this object, a dehumidifier control apparatus of the present invention comprises a humidity detecting means for detecting the humidity of a room, a humidity setting means for switching a humidity set value stepwise. Signal output means for operating or stopping the compressor of the refrigerating means is provided according to the output signal of the comparing means.

[0008]

In this configuration, the humidity set value can be switched, so that the humidity can be controlled over a wide range to meet the demand of use.

【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 parts as those described in the above-mentioned conventional example are designated by the same reference numerals, and the description thereof will be omitted.

As shown in FIG. 1, the control device 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 that receives the detection signal to determine the operation mode, a humidity setting circuit 22 that receives the input of the humidity setting means 21 that switches the humidity setting stepwise, and sets the humidity value, the determination circuit 20 and the humidity setting circuit 2.
An output relay circuit 23 that receives the output of 2 and drives the compressor 5 and the blower 10 is provided.

The operation of the dehumidifier control apparatus having the above-described configuration 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 it. A command for driving the compressor 5 and the blower 10 is output to the relay circuit 23.

When the second switch 17 is selected, the determination circuit 20 determines that the humidity of the room is the humidity value set in the humidity setting circuit 22 (for example, in FIG. 2) based on the detection signal of the humidity sensor 19. 40%, 50% or 6 as shown
When any humidity value of 0%) is exceeded, the compressor 5 is stopped and only the blower 10 is driven. If the detection signal of the humidity sensor 19 causes the room humidity to exceed the humidity value set in the humidity setting circuit 22, the compressor 5 stops operating.
The operation of is restarted and the dehumidifying action is performed.

As described above, according to this embodiment, the humidity set value can be switched stepwise, so that the humidity set value in a wide range other than the one-point humidity value which has been set as an appropriate humidity up to now. You can use the dehumidifier.

(Second Embodiment) A second embodiment of the present invention will be described below.

As shown in FIG. 3, the feature of the present embodiment is that a storage circuit 24 for storing the previous humidity value set by the humidity setting circuit 22 is added to the structure of the above-described first embodiment. is there.

With this configuration, when the first switch 16 is selected, the operation is the same as that of the first embodiment, but when the second switch 17 is selected, the operation stop switch 15 is not turned off. The humidity set value becomes the immediately preceding humidity set value, and when continuously operating without changing the humidity set value in a certain place, once setting the desired humidity for use, the humidity setting means 21 is not switched every time the operation is turned on and off. Also, even if the user forgets to set the humidity, it is automatically operated at the immediately preceding humidity set value, so that the room humidity can be prevented from becoming a value other than the humidity set value.

(Embodiment 3) A third embodiment of the present invention will be described below.

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

With this configuration, when the operation stop switch 15 is turned off and the operation is performed again, if the humidity setting value at the immediately preceding operation is not stored in the storage circuit 24, the humidity setting value becomes the minimum. Since the automatic setting circuit 25 is provided as described above, it is possible to prevent the operation from being started from the high humidity setting, reduce the safety and discomfort in the operating space, and eliminate the environment under the condition not suitable for the high humidity.

[0022]

As is apparent from the above description, according to the present invention, the humidity detecting means for detecting the humidity of the room, the humidity setting means for gradually changing the humidity set value, and the output signal of the comparing means are used. With the configuration provided with the signal output means for operating or stopping the compressor of the refrigerating means, it is possible to realize an excellent dehumidifier control device capable of arbitrarily selecting a desired humidity value corresponding to the application.
