Description

[Detailed Description of the Invention] The present invention relates to a humidifier, and more particularly, to an ultrasonic humidifier that humidifies using the atomization effect of ultrasonic waves.

In an ultrasonic humidifier, ultrasonic waves generated by a piezoelectric vibrator form a water column on the water surface, generate fog, and emit the fog by carrying it on air blown by a blower or the like.

In this case, large water droplets are generated on the water column, but when these water droplets fall onto the water column, there is a problem in that the atomization efficiency decreases.

Therefore, there is a demand for the development of a means to prevent water droplets from falling directly onto the water column, and various structures have been proposed so far.

However, the existing ones have mechanical problems, and further improvements are desired.

The present invention was developed in view of this point, and the large water droplets of the water column generated by the ultrasonic vibrator are guided to fall onto a float at a different position from the water column, thereby increasing the atomization efficiency. The purpose of this invention is to prevent a drop in the temperature of the humidifier, and also to ensure that the float functions properly and prevent the humidifier from running dry.

The present invention forms an atomization chamber with a water tank at the bottom inside the humidifier body, and the water tank of this atomization chamber is equipped with an ultrasonic vibrator that atomizes water by its oscillation action. In a water tank at a position different from the position of the atomization chamber, float a float that activates a switch that stops the operation of the ultrasonic transducer by lowering it close to the bottom plate of the water tank, and integrally fix its upper end to the side wall of the atomization chamber. A drip-blocking plate is provided with its lower end facing the upper part of the float and inclined so that large water droplets generated by the ultrasonic vibrator are guided to fall onto the float guard, and is installed in the atomization chamber. It is characterized by being equipped with a blower that blows humidified air! be.

Next, one embodiment of the present invention will be explained with reference to the attached drawings.

,..., □ 1 1 is a humidifier main body, and this main body 1 has an air regulating plate 3 which serves as a side wall vertically disposed approximately in the center of a top plate 2, and this air regulating plate 3
The lower end of the tank extends to the water tank 4.

The interior of the main body 1 is divided into an atomization chamber 5 and a ventilation chamber 6 by the air conditioning plate 3.

Further, a ventilation hole 7 is formed in the middle of the air conditioning plate 3 to communicate the atomization chamber 5 and the ventilation chamber 6, and the water tank 4
A water column guide hole 9 is formed in a guide plate 8 that extends horizontally from the upper surface of the air conditioning plate 3 and is integrally formed with the air regulating plate 3.

Further, a support frame 10 having a cross-sectional shape is integrally formed with the main body 1 at one end of the water tank 4, and a water narrow guide hole 12 is bored in the center of the top plate 11 that controls the float of the support frame 10. ing.

A float 13 is housed within this support frame 10, and a magnet 14 is fixed to the lower surface of this float 13.

Further, on the bottom plate of the water tank 4, a reed switch 15 is fixed, which is located in the support frame 10 and is operated by the magnet 14 of the float 13, and is located directly below the guide hole 9 of the guide plate 80. An ultrasonic vibrator 16 electrically connected to the reed switch 15 is fixed thereto.

Further, a drip blocking plate 17 is integrally attached to the upper part of the air regulating plate 3.

This droplet shielding plate 17 is arranged in the guide hole 9 in the atomization chamber 5.
The support frame 10 is provided at an inclined position, and its lower end is located above the water drop guide hole 12 formed in the top plate 11 of the support frame 10.

The large-diameter water droplets in the water column 18 ejected from the guide hole 9 are guided by the droplet shielding plate 17 and fall onto the float 13.

Next, a duct 19 is provided in the ventilation chamber 6, and a blower 20 is provided at the bottom of this duct 19.
The air is blown by the air outlet 2 formed in the upper part of the duct 19.
1, the air is guided into the atomization chamber 5 through the ventilation hole 7 through the inside of the ventilation chamber 6.

Further, an air exhaust hole 22 communicating with the inside of the atomizing chamber 5 is formed on one side of the upper plate 2 of the main body 1, that is, on the upper plate 2 at the upper part of the atomizing chamber 5, and this air exhaust 7L, ? A blowout looper 23 is attached to 2.

In this configuration, the air sent out by the drive of the blower 20 passes through the air outlet 21°, the air chamber 6, and the air hole 7, and the water column 18 generated by the ultrasonic vibrator 16 in the atomization chamber 5. At this time, this becomes humidified air 24 containing mist, which is sent out from the blow-off looper 23 through the atomization chamber 5 to humidify the room.

In this case, among the mist generated by the ultrasonic vibrator 16, large water droplets hit the droplet shielding plate 17, and flow along the inclined surface of the droplet shielding plate 17 from the lower end of the droplet guiding hole 12 onto the float 13. Be fallen.

The float 13 is shocked by the concentrated falling water droplets and floats following the water surface without coming into close contact with the supporting frame 10 or its upper surface 11.

Further, when the water in the water tank 4 becomes insufficient or the amount of water becomes insufficient to generate the water column 18, the float 13 approaches the bottom plate of the water tank 4.

Then, the magnet 14 of this float 13 operates the reed switch 15, which is electrically connected to the reed switch 15, and also stops the oscillation of the ultrasonic transducer 16.
Dry operation of the ultrasonic transducer 16 is automatically prevented.

Next, in the embodiment described above, the shielding plate 17 has a smooth surface for guiding water droplets to the water column 18, but the water droplet guiding surface 25 extends in the length direction, that is, in the water droplet guiding direction, as shown in FIG. A large number of guide grooves 26 may be formed in the float 13, and large water droplets may be guided to fall onto the float 13 through each guide groove 26.

Alternatively, a cloth or porous breathable member 27 may be provided vertically at the lower end of each of the drip-shielding plates 17, and water droplets may be guided to fall onto the float 13 through this member 27.

As a result, two parts of the water droplets evaporate while falling down the member 27, thereby promoting the humidification effect.

According to the present invention, among the water columns generated by the ultrasonic vibrator, relatively large water droplets are emitted from the droplet shield plate? The water is flown down along a guiding slope, and is reliably guided to fall onto a floating float located at a position different from that of the ultrasonic transducer, that is, on the outside of the water column.

Therefore, there is no risk that these large water droplets will fall onto the water column, so the atomization efficiency will not decrease, and humidification can be promoted in conjunction with the air blowing by the blower. are dropped onto the float in a concentrated manner, so that the shock reliably prevents the float from coming into close contact with the inner wall of the aquarium, and allows it to smoothly follow fluctuations in the water level.

Also, when the water level drops and the float falls close to the bottom plate of the aquarium, this float activates a switch, and the operation of this switch reliably stops the operation of the ultrasonic transducer, thereby preventing water from running out in the aquarium. It is possible to reliably prevent the ultrasonic transducer from running idly under such conditions.
