Description

[Detailed Description of the Invention] The present invention relates to an ultrasonic humidifier having an air blower that blows air intensively toward a water column formed in a water storage tank by irradiating ultrasonic waves.

A conventional ultrasonic humidifier uses an ultrasonic vibrator installed at the bottom of the aquarium to irradiate ultrasonic waves to water stored in the aquarium to form a water column on the water surface directly above the ultrasonic vibrator. The microscopic water droplets (mist) that ooze out around the water column are blown into the room using a blower.

However, in such a configuration, large water droplets that fall from the water column formed by ultrasonic irradiation to the surrounding water surface fall onto the water surface where the ultrasonic waves are irradiated, temporarily inhibiting the formation of the water column, and the amount of fog generated decreases. It has the disadvantage of causing a so-called breathing phenomenon that changes over time.

The present invention was developed in view of the above circumstances, and the purpose is to provide an ultrasonic humidifier that can significantly improve atomization efficiency, prevent the breathing phenomenon, and stabilize the amount of mist generated. do.

An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 designates a base on which a water tank 2 is formed, and a blower device 6 consisting of an oscillating device 3, a motor 4, and a blower blade 5 is disposed at the bottom of the water tank 2, and the lower opening 1a of the base 1 is a support leg. 7 is closed by a bottom plate 8.

Reference numeral 9 denotes a cover having an atomization chamber 10, which is attached to the upper part of the base 1 and has left and right side walls 9a and 9b facing into the water storage tank 2.

Reference numeral 11 indicates a water storage tank 2 corresponding to approximately the center of the atomization chamber 10.
An ultrasonic vibrator installed at the bottom of the oscillator 3.
high frequency power is applied.

Reference numeral 12 denotes a ventilation opening formed on the left side wall 9a of the cover 9 so as to face the ultrasonic transducer 11;
It is formed into a narrow vertically elongated shape that opens at the lower end of a, and its width and height are set approximately equal to the width and height, respectively, of the water column 20 formed as described below. .

Reference numeral 13 denotes an air passage that communicates the air outlet 12 with the air blower 6 through the left side wall 9a of the cover 9 and the left side wall 2a of the water tank 2 and between the left side wall 2a and the left side wall 1b of the base 1. , an air intake port 8 formed in the bottom plate 8 by the air blower blade 5 of the air blower 6
The outside air sucked from a is blown into the atomization chamber 10 through the air passage 13 and the air outlet 12.

14 is a discharge port formed at the top of the cover 9.

Reference numeral 15 denotes a water supply tank that is removably placed on the upper part of the base 1, and a water supply cap 16 is screwed onto the water supply port (not shown) of this tank. A valve body (not shown) that opens and closes the valve body and a valve rod 17 that opens and closes this valve body are provided so as to be movable up and down.

Reference numeral 18 denotes a coil spring that urges the valve stem 17 downward, and when the water supply tank 15 is placed on the mounting portion 1C of the base 1, the tip of the valve stem 17 connects to a water guide groove that communicates with the water tank 1. The bottom portion of the valve body 19 is pushed upward against the biasing force of the coil spring 18, and the aforementioned valve body is opened.

Next, the operation of this embodiment configured as described above will be explained.

When the water tank 15 is placed on the mounting part 1C of the base 1,
The valve stem 17 is pushed upward against the coil spring 18 to open the valve body, and the water in the water supply tank 15 is supplied into the water storage tank 2 via the water guide groove 19 up to a certain water level according to the so-called Mariotsud principle. be done.

Now, when the oscillation device 3 and the motor 4 of the blower device 6 are energized via a switch (not shown), the ultrasonic vibrator 11 receives high-frequency power from the oscillation device 3 and causes thickness resonance vibration, causing the inside of the water tank 2 to be energized. By irradiating water with ultrasonic waves, a water column 20 is formed in the water in the water storage tank 2.

On the other hand, the air is sucked from the air inlet 8a by the air blower blade 5 of the air blower 6, and the air is sucked into the atomization chamber 10 through the air passage 13 and the air outlet 12.
Since the width and height of the air outlet 12 are set to be approximately equal to the width and height of the water column 20, the wind blown into the atomization chamber 10 increases in wind speed and is narrow. water column 2
Air is blown intensively towards 0.

The water column 20 is tilted in the opposite direction to the air outlet 12 due to the pressure of the air intensively blown from the air outlet 12.

Therefore, since the water column 20 is inclined, the large water droplets 21 that fall from the water column 20 due to gravity are exclusively concentrated on the water column 20.
The water droplets 21 fall into the water tank 1 from the upper end, and the water droplets 21 fall from the base of the water column 20 to the water surface on the opposite side to the air outlet 12.

Further, fine water droplets (fog) generated so as to ooze out from around the water column 20 are blown out of the cover 9 from the discharge port 14 together with the wind blown into the atomization chamber 10, thereby humidifying the atmosphere.

In this way, according to this embodiment, the large ice droplets 21 falling from the water column 20 fall at a location away from the water surface directly above the ultrasonic transducer 11, so that unlike the conventional structure, the large ice droplets 21 falling from the water column are The fog generated by inhibiting the formation of a water column does not cause a suffocation phenomenon, and the atomization efficiency can be greatly improved.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings; for example, the height of the air outlet 12 may be approximately equal to the height of the water column 20; It may be formed into a vertically elongated shape with a width substantially equal to that of the water column and a height equal to or less than the water column, and various modifications may be made without departing from the scope of the invention.

As described above, the present invention can provide an ultrasonic humidifier that can reliably prevent the breathing phenomenon and greatly improve the atomization efficiency.
