BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIG. FIG. 1 is a main block diagram of a humidifier control device according to a first embodiment of the present invention, and FIG. 2 is a flowchart showing an operation program of the first embodiment stored in a microcomputer. In FIG. 1, 1 is an operation switch, 2 is a humidity sensor for detecting indoor humidity, 3 is a humidity setting switch for setting a target humidity, and 4 is a current humidity detected by the humidity sensor 1 and set by a humidity setting switch 3. The determination means performs comparison determination with the set humidity, and on / off determination of the operation switch 1 and a changeover switch described later. In the case of the humidity determination performed when the operation switch 1 is turned off, the predetermined value is multi-step. Is set. Reference numeral 5 denotes control means for controlling the operation of the entire humidifier based on the determination result of the determination means 4, and reference numeral 6 denotes a display means for displaying a set humidity, a current humidity, and the like.

[0010] 8 is a heating device for generating steam,
9 is a changeover switch for turning on and off the humidity judgment operation by the judgment means 4 when the operation switch 1 is turned off;
Is a notifying means for giving a warning or a warning based on the result of the judgment by the judging means 4, 10 is a blower for sending steam out of the apparatus, and 11 is a microcomputer constituting the judging means 4 and the control means 5.

Next, the operation of the first embodiment of the present invention will be described with reference to the flowchart of FIG. First, in step 20, on / off determination of the operation switch 1 is performed,
When the operation switch 1 is on, a humidifying operation similar to that of the conventional humidifier is normally performed. Here, if the operation switch 1 is turned off, and if the indoor humidity is to be determined even while the operation switch 1 is off, the changeover switch 9 is turned on in step 21. Next, in step 22, the microcomputer 11 reads the indoor humidity by the humidity sensor 2, and inputs the current humidity detected by the humidity sensor 2 to the determination means 4.

Next, in step 23, step 2
2 is lower than a first predetermined value set in advance (in the first embodiment, a humidity of 35% is required, which generally warns the human throat and makes the skin dry and warns). The determination unit 4 determines whether the value is low. Next, if it is determined in step 23 that the current humidity is lower than the first predetermined value, step 2
At the same time, an alarm sound is issued as a warning from the notifying means 7 at step 4, and at the same time, the microcomputer 11 displays on the display means 6 at step 25, and proceeds to the next step 29.

Next, in step 23, if the humidity is not below the first predetermined value (35% humidity), the current humidity read in step 22 in step 26 is higher than the first predetermined value. The determination means 4 determines whether the predetermined value is lower than a predetermined value of 2 (in the first embodiment, a human feels a feeling of dryness in the throat, deviates from the appropriate humidity, and sets a humidity of 40% that requires attention). Next, step 2
If it is determined in step 6 that the humidity is lower than the second predetermined value (humidity 40%), the notifying means 7 emits a melody sound as a caution in step 27, and the microcomputer 11 in step 28 Is displayed, and the process proceeds to step 29.

Next, in step 29, the microcomputer 11 makes a decision as to whether or not the changeover switch 9 is off by the decision means 4, and if it is on, returns to step 22 and repeats the above flow. If the changeover switch 9 has been turned off, the process ends.

Embodiment 2 In the first embodiment, the determination as to whether the current humidity is lower than a predetermined value is performed in two stages of a first predetermined value of steps 23 to 25 and a second predetermined value of steps 26 to 28. Although it is performed, the same effect can be obtained even if the number of steps is increased, and the more steps, the more attention and warning can be notified in detail.

Embodiment 3 In the first embodiment, the first predetermined value and the second predetermined value are respectively fixed values. However, the first predetermined value and the second predetermined value may be arbitrarily set. In this case, even if the humidity environment differs from home to home, if the setting is made according to the humidity environment of the home, it is possible to eliminate the problem that the alarm is not easily issued or it is frequently emitted, so the user's favorite Attention or warning can be given based on humidity.

Embodiment 4 Further, in the first embodiment, the alarm sound that is generated when the humidity is lower than the first predetermined value and the melody that is generated when the humidity is higher than the first predetermined value and lower than the second predetermined value are generated. Although each is fixed, the alarm sound and the melody may be arbitrarily set by key input. In this case, the sound of the caution and the warning can be changed according to a predetermined value to be compared. The warning can be made easier for the user to understand.

[0018]

As described above, according to the present invention, a predetermined value set in advance is set in multiple stages, and if the current humidity in the room is lower than each predetermined value, caution or warning is issued when the current humidity is lower than each predetermined value. The low-humidity timing is not missed, and the magnitude of the low-humidity can be easily determined.

According to the second aspect of the present invention, in addition to the same effect as described above, the notification sound can be arbitrarily changed according to the stage, so that the low humidity can be understood for each state, and
It can be easily determined whether the notification is a warning notification or a warning notification.

According to the third aspect of the present invention, in addition to obtaining the same effect as described above, the predetermined value of the determined humidity can be arbitrarily changed, so that it is possible to cope with a case where the humidity environment differs between homes. Can be set according to the user's preference, which is extremely convenient in use.
