Abstract

PURPOSE:To provide a controller for a humidifier in which an operation of the humidifier is urged by sensing humidity even when an operation switch is turned OFF, and generating an alarm in the case of a low humidity to need an operation of the humidifier. CONSTITUTION:Even when an operation switch 11 is OFF, a humidity of a room is sensed by a humidity sensor 1. Whether the sensed humidity is lower than a predetermined value or not is decided by deciding means 4. If the sensed humidity is lower than the value, an alarm is output from warning means 12. These operations are conducted based on a program of a microcomputer 15.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a humidifier control device for automatically performing appropriate humidification control according to the temperature and humidity in a room.

[0002]

2. Description of the Related Art Generally, humidification in a humidifier is performed by a method in which a fixed amount of humidification is always set by a humidification amount set by human senses regardless of indoor humidity. Occasionally, there was a problem that was performed.

For this reason, regarding the amount of humidification of the humidifier, it is necessary to make an appropriate humidification by comprehensively judging the temperature and humidity of the room where the humidification is performed.

Therefore, conventionally, a humidifier as shown in FIG. 12 has been proposed. FIG. 12 is a block diagram of the humidifier disclosed in Japanese Unexamined Patent Publication No. 5-52392, 37 is a humidity sensor, 38 is a room temperature sensor, 39 is a humidity setting button,
45 is a microcomputer, 40 is a humidification amount determination means,
Reference numeral 41 is water vapor generation control means, 42 is display control means, 4
Reference numeral 4 is a steam generator, and 43 is an indicator.

The conventional humidifier is constructed as described above,
When the operation switch (not shown) is turned on, the humidity sensor 37 detects the room humidity, and the detected value and the set value set by the humidity setting button 39 and the room temperature sensor 38.
The humidification amount determination means 40 comprehensively determines from the room temperature and the like detected by the above, and based on the determination, the steam generation amount control means 41 drives the steam generation device 44 to perform humidification, and the display control means 42 The current humidity and the set humidity of the room were displayed on the display unit 43.

[0006]

As described above, in the conventional humidifier, the humidity is detected and displayed by turning on the operation switch. Therefore, when the operation switch is turned off, the humidity is not displayed and the room is not displayed. If there is no other hygrometer, the dry state cannot be known, so that there is a problem that the humidifier cannot be used effectively by delaying the timing of humidification.

The present invention has been made in order to solve the above problems, and the humidity is so low that the humidifier needs to be operated even when the operation switch is off. In this case, it is an object to obtain a humidifier control device that can promptly operate the humidifier at a proper timing.

[0008]

A humidifier control device according to the present invention includes an operation switch for turning on and off an operation, a humidity sensor for detecting indoor humidity, and a humidity sensor while the operation switch is off. It is provided with a judging means for judging whether or not the humidity detected by is lower than a predetermined value, and a warning means for issuing an alarm if the humidity is lower than a predetermined value.

[0009]

In the humidifier controller according to the present invention, the determination means determines the detection signal from the humidity sensor on the basis of a predetermined value while the operation switch is off.
When the humidity is low, the warning means gives an alarm.
