Further, according to the present invention, in a humidifier containing a water tank for storing water for humidification, a float that moves up and down according to the water level in a water supply tank for supplying water to the water tank, and the float has an upper limit water level. The first that works at certain times
And a second warning means that is activated when the float is at a lower water level.

[0007]

In the humidifier of the present invention, when the water level in the water tank is abnormal, the operation automatically stops and
When the abnormality is caused by the rise of the water level in the water tank, a warning is given by a lamp or buzzer. further,
When the amount of water in the water tank is full or empty, the same is warned by a lamp or buzzer.

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a sectional view showing an embodiment of the humidifier of the present invention. Although the humidifier main body is shown in FIG. 1 as having an external shape that matches the interior of the room, the humidifier of the present invention is not limited to such external shape. In FIG. 1, 2 indicates a float that moves up and down according to the water level of a water tank 3 built in the humidifier 1, and 4 indicates up and down according to the water level of a water supply tank 5 that supplies the water for humidification to the water tank 3. Indicates a float to do.

Water is stored in the water supply tank 5 through the water injection port 17, and is supplied to the water tank 3 from here.
An ultrasonic transducer 7 is attached to the bottom surface of the water tank 3. 8
Is a fan casing mounted below the water tank 3. Inside the casing 8, a fan 10 mounted on the output shaft of a motor 9 is arranged. The motor 9 and the fan 10 form a blower 11, and the air sucked from the intake port 12 by the drive of the blower 11 receives the communication port 13 and the blower tube.
14, jetted from the spray port 16 to the outside through the spray tank 15 and above the water tank 3. In this way, the water atomized by the ultrasonic transducer 7 is sprayed to the outside.

The operation of the float 2 in FIG. 1 is shown in FIG.
The float 2 is attached to the cylindrical portion 24 extending upward from the bottom surface 31 of the aquarium 3.
Is mounted so that it can move up and down. 23 is a magnet attached to the float 2. When the float 2 is at the normal water level, the ultrasonic vibrator 7 and the blower 11 are activated, and when the float is at the upper limit water level or the lower limit water level, the ultrasonic vibrator 7 and the blower 11 are stopped as a detection means. In the example, the reed switch 21 for detecting water shortage is used. Further, the high water level detection reed switch 22 is used as a warning means that operates when the float 2 reaches the upper limit water level. When the float 2 is at the normal water level indicated by the dotted line, the switch 21 is turned on by the action of the magnet 23, and the humidifier operates normally. At this position, the reed switch 22 is in the OFF state.

Next, it is assumed that the water level in the water tank 3 rises due to some condition and the float 2 reaches the position shown by the solid line. At this time, the switch 21 is turned off and the humidifier is stopped. On the other hand, the reed switch 22 is turned on by the action of the magnet 23, and a warning means (not shown) such as an abnormality indicator lamp or a warning buzzer that is connected to the reed switch 22 is activated to notify that the humidifier has stopped due to the rise of the water level. Inform. From this, it can be known from the outside that the stop of the humidifier is caused by the rise in the water level.

Further, when the water level in the water tank drops and becomes almost empty (the state shown by the alternate long and short dash line), both the switch 21 and the switch 22 are turned off and the humidifier is stopped. In this case, water may be supplied to the water supply tank 5 when it is noticed. It is also possible to provide another reed switch and activate the warning means as described above in this case as well. At this time, it is preferable that the warning indicating the rise of the water level and the warning indicating the fall of the water level are provided in different forms to distinguish them.

FIG. 3 shows a sectional view of the float 4 which moves up and down according to the water level in the water supply tank 5 in FIG. The figure shows a state in which the water in the water supply tank 5 is almost empty. At this time, the reed switch 42 is turned on by the action of the magnet 61 attached to the cover 6 of the water supply tank 5, the lamp 45 is turned on, and it is displayed that the water in the tank 5 is almost empty.

From this state, when the tank 5 is replenished with water and the water in the tank 5 becomes almost full, the float 4 rises and the reed switch 41 approaches the magnet 61. And the reed switch 41 is turned on by the action.
In this state, the lamp 44 is turned on to indicate that the water in the tank 5 is almost full. Lamp 44 and
45 is turned on by the lithium battery 43 built in the float 4.

When in the middle of these states, both reed switch 41 and reed switch 42 are off.
Then, the lamp 44 and the lamp 45 are both turned off.

It is preferable that the lamps 44 and 45 use different colors to facilitate the distinction.
