Description

[Detailed Description of the Invention] The present invention relates to an improved structure of an ultrasonic humidifier equipped with a drop type water supply tank.

This type of humidifier supplies water from a water supply tank to an atomizing water tank equipped with a vibrator, and maintains the water level at which the vibrator's atomizing ability can be fully utilized.On the other hand, an atomizing cylinder is hung from above into the atomizing water tank. The indoor air is circulated from the top of the atomizing water tank through the atomizing cylinder, and the mist generated during that time is transported.

Here, since the water supply tank supplies water while replacing it with outside air when the water level of the atomization water tank falls, there is a predetermined amount of air in the tank.

Therefore, this humidifier is often used at the same time as heating operation, but the air in the water tank also reaches the heating temperature according to the surrounding temperature, and this causes the ambient temperature to drop rapidly when heating is not performed at night. It is cooled and contracted accordingly.

Due to this contraction, the air pressure inside the water supply tank decreases and water tries to flow back into the tank from the water supply port of the water supply tank, but if there is a gap between the water supply port and the water surface, the water inside the water tank will flow through this gap. Air flows into the water tank to replace the outflow water.

Due to these effects, the amount of air in the water tank increases before and after the ambient temperature drops.

As a result, when heating operation is started again and the ambient temperature rises, the air in the tank expands and the volume occupied by the air increases compared to before the ambient temperature dropped, so this increased amount of water in the tank is atomized into the aquarium. to raise the water level in the iron tank.

This rise in water level will reduce the atomization ability of the vibrator the next time it is activated, but if this water level rises further above the bottom of the atomizer tube, the flow path for indoor air will be cut off, resulting in a situation where the mist cannot be sent out from the atomizer tube. becomes.

The present invention was developed to solve this problem, and an embodiment thereof will be described below with reference to the drawings.

1 is a tank body in which an atomizing water tank 2, a water supply tank 3, and a tank mounting stand 4 are successively molded in the horizontal direction, and a partition is provided between the atomization water tank 2 and the water supply tank 3 to allow both tanks to communicate only at the bottom. A plate 5 is integrally formed, and a side wall 7 is integrally formed on one side of the atomizing water tank 2 at a distance 6.

Reference numeral 8 denotes a box-shaped main body that supports the end of the tank mounting table 4 and the lower end of the side wall 7 by covering the upper opening thereof.

A spray body 9 is detachably attached to the upper end of the side wall 7 and the partition plate 5 to cover the upper part of the atomization water tank 2, and it hangs downward into the atomization water tank 2 and is connected between the water surface and both sides of the water tank 2. The atomizing tubes 11 are spaced apart from each other by a distance 10, and the atomizing tubes 12 communicate with the atomizing tubes 11 into the room.

Reference numeral 13 denotes a vibrator mounted on the inner bottom surface of the atomizing water tank 2 at a small angle, 14 is a driving circuit thereof, and 15 is a suction of indoor air and guiding it to the atomizing water tank 2 through intervals 6 and 10. , a fan that transports the mist from there and sends it out from the atomizing tube 11 and the atomizing tube 12.

Reference numeral 16 denotes a drop-type water tank that is removably placed on the tank mounting table 4. A water inlet 17 is provided on the bottom facing the water tank 3, and a normally closed water valve is connected to the water inlet 17 by a spring. There are 18.

Here, the water supply valve 18 has an operating rod 19 protruding downward for opening.

Reference numeral 20 denotes a resilient gasket that closes a hole provided in the bottom of the water tank 3 facing the lower end of the operating rod 19, and 21 drives a solenoid 22 that comes into contact with the lower end of the operating rod 19 from below by sandwiching this gasket 20. It is a rod.

Here, the solenoid 22 is operated simultaneously with the vibrator 13 and the fan 15 to raise the drive rod 21, push up the operating rod 19, and open the water supply valve 18.

Thus, the vibrator 13, the fan 15 and the solenoid 22
When the atomizing water tank 2 is activated, the mist generated above the atomizing water tank 2 is sent out together with the indoor air, and the water in the water tank 2.3, which has decreased due to use, is replenished from the water tank 16 via the water supply valve 18.

During use, the temperature inside the tank is high to match the heating temperature, but when the tank 16 is not in use, such as at night, the ambient temperature drops rapidly and the air inside the tank 16 is cooled and contracts.

Due to this contraction, the air pressure inside the water tank 16 decreases, and water flows back into the tank 9 from the water supply port of the water tank 16.
Air tends to flow into the water supply tank 16 due to this backflow.

However, since the solenoid 22 is deactivated when not in use, the water supply valve 18 is also closed by the spring, and air does not flow into the water tank 16 when not in use, and the ambient temperature rises again as in the conventional case. Water does not rise and flow out from the water supply tank 16, and the atomization water tank 2
There is no possibility that mist delivery will not be possible due to a rise in the water level.

In this way, the humidifier according to the present invention is equipped with a normally closed water supply valve at the water supply port of the water supply tank that supplies water to the atomization water tank, and this water supply valve is controlled to open and close by a driver that is linked to the drive of the vibrator and the fan. When the product is not in use, there is no air flowing into the tank, and when the product is reused, the ambient temperature rises, causing the water level in the atomization tank to rise unnecessarily, reducing the atomization ability of the vibrator, or rendering it unusable. It will never happen.

Further, since the driving body is linked to a vibrator or the like, there is an advantage that there is no possibility of making a mistake in operation.
