Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an ultrasonic humidifier, and more particularly to an ultrasonic humidifier configured to blow out only mist generated by ultrasonic waves having a small particle size. Regarding

[Conventional technology]

An ultrasonic humidifier atomizes water using an ultrasonic transducer,
The mist blows out to the outside, but the mist generated by the ultrasonic transducer is not only small in particle size, but if it is discharged to the outside as it is because the particle size is large, it will fall on the floor etc. as water droplets. It also includes those that do not contribute to the humidifying action by wetting the floor surface and the like.

Therefore, to prevent the floor surface from getting wet, an ultrasonic humidifier (see No. 56-119928) is provided that blows out only the small mist generated by the ultrasonic transducer to the outside. Has been reached.

The ultrasonic humidifier is provided with a mist guide nozzle on a water tank, and the mist guide nozzle expands continuously upward from the lower half portion of the cylinder and the rear portion of the lower half portion in a substantially semicircular shape rearward. A rear wall that has come out, a rising front portion that extends from the front portion of the lower half portion to a height corresponding to a substantially intermediate height position of the rear wall, and a baffle plate that extends backward from one end of the rising front portion. , Is formed by a guide plate that extends obliquely forward and upward from this baffle plate,
It had an exposure port on the upper part. According to this ultrasonic humidifier, the mist generated by the ultrasonic vibrator once collides with the baffle plate, and as a result, those with a large particle size fall into water droplets and drop with a small particle size. It was blown out from the exposed mouth.

However, in the above ultrasonic humidifier, it is not always possible to select only those having a sufficiently small particle size, and those having a large particle size are also blown out to the outside, which can sufficiently prevent the floor surface and the like from getting wet. Nakatsuta. It is considered that this is because the ratio of the mist having a large particle diameter colliding with the baffle plate among the mist generated by the ultrasonic transducer is not so large.

[Problems to be solved by the device]

The present invention has been made in view of the above prior art, and an object thereof is to provide an ultrasonic humidifier capable of sufficiently preventing the floor surface and the like from getting wet.

[Means for solving the problem]

In order to solve the above-mentioned problems, the present invention has an introduction path through which generated fog is introduced, and a plurality of outlets that are branched from the introduction passage and open to the outside, and the above-mentioned branch is provided at the branch portion of the outlet. The configuration is provided with an injection nozzle in which a substantially hemispherical surface having substantially the same diameter as the inner diameter of the introduction path is formed.

[Action]

According to the present invention, the generated fog is blown out to the outside through the introduction passage and the blowout passages branched from the introduction passage. Since a substantially hemispherical surface having a diameter substantially the same as the inner diameter of the introduction passage is formed at the branch portion of the blowout passage, the generated fog having a large particle diameter has a strong straight-running property. Almost all of the large ones collide with the above-mentioned hemispherical surface when entering each outlet from the introduction passage, and as a result, most of the fog generated has a large particle diameter and drops downwards and blows out to the outside. Only those having a small particle size will be sufficiently selected and rectified along the substantially hemispherical surface of the branch portion and blown out to the outside, sufficiently preventing the floor surface and the like from getting wet. be able to. That is, unlike the so-called general baffle plate, the substantially hemispherical surface formed in the branch portion of the present invention does not cause turbulent flow, so that the generation of water droplets caused by collision of fog due to the turbulent flow is suppressed. Is something that can be done.

〔Example〕

 The present invention will be described below based on the embodiments shown in the drawings.

FIG. 1 shows an ultrasonic humidifier (a) according to an embodiment of the present invention.
2 is a sectional view taken along the line II-II in FIG. 1, FIG. 3 is an enlarged perspective view of an essential part, and FIG. 4 is a sectional view in FIG.
Fig. 5 is a sectional view taken along line IV-IV, and Fig. 5 is a sectional view taken along line VV in Fig. 3.

In these drawings, (1) is a water tank, (2) is a float switch that detects the water level of the water (3) in the water tank (1), (4) is a corrugated plate that prevents corrugation of the water surface, and (5 ) Is an outlet for discharging the water overflowing from the water tank (1),
(6) is an outlet for discharging the water (3) in the water tank (1), (7) is an ultrasonic transducer for atomizing the water (3) in the water tank (1), and (8) is external Intake port that takes in the air of
(9) is an air filter provided at the intake port (8),
(10) is a blower, (11) is a motor for driving the blower (10), (12) is an intake passage, (13) is an electrical equipment space in which an oscillation circuit (not shown) and other electric parts are arranged, (14) ) Is a mist tube for guiding the mist generated by the ultrasonic transducer (7),
(B) is a spray nozzle provided at the tip of the mist guide tube (14), and these constitute the ultrasonic humidifier (a). The mist guide tube (14) is inclined upward after being raised upward. In addition, the mist guide tube (14) may simply be raised up.

In the present invention, the injection nozzle (b) has an introduction passage (20) into which the generated mist is introduced, and a discharge passage (21) that is branched into a plurality of portions from the introduction passage (20) and opens to the outside.
And the introduction path (20) at the branch portion of the outlet path (21).
The structure is such that a substantially hemispherical surface (22) having a diameter substantially the same as the inner diameter of is formed. Specifically, the substantially hemispherical surface (22) has the same diameter as the introduction path (20) as shown in the embodiment of the drawing, or has a diameter larger than that.

In the case of the embodiment shown in the drawings, the spray nozzle (b) is formed by integrally molding a tubular member (23), an inner wall member (24) and an outer wall member (25) as shown in FIGS. There is. The inside of the tubular member (23) serves as the introduction path (20), and one end of the tubular member (23) has the mist guide tube (14).
Is connected to the distal end of the nozzle by press fitting or the like, and the mist generated by the ultrasonic transducer is introduced into the introduction path (20) through the mist guide tube (14). Also, the inner wall member (24)
Is configured such that the tip forms a substantially hemispherical surface (22) and the periphery forms a substantially cylindrical surface (26) continuous with the substantially hemispherical surface (22). The tubular member (23) is arranged so as to face the opening (23a) at the other end of the tubular member (23) with an appropriate gap, and the substantially hemispherical surface (22) at the tip is the blowout passage (21).
It serves as a branch point. Further, the outer wall member (25)
Is provided so as to cover the periphery of the inner wall member (24) continuously with the other end of the tubular member (23). Then, the outer wall member (25) and the positions on both sides of the substantially cylindrical surface (26) around the inner wall member (24) are in a joined state, and between the outer wall member (25) and the inner wall member (24). The outlet passage (21) is branched into two, and the outlet passage (21) is opened to the outside.

In the case of the embodiment shown in the drawings, an annular guide protrusion (28) is provided on the inner periphery of the opening side (inner wall member (24 side)) at one end of the tubular member (23). The guide projections (28) guide the fog toward the vicinity of the approximate center of the substantially hemispherical surface (22) when the fog enters each of the outlet passages (21) from the introduction passage (20), and the fog particles Those having a large diameter further increase the ratio of collision with the substantially hemispherical surface (22). It is desirable to provide the guide protrusions (28) as described above, but it is not always necessary to provide the guide protrusions (28) in the present invention. The guide protrusion (28)
Instead of the above, even if the tubular member (23) is tapered toward the inner wall member (24), the same action as that of the guide projection (28) can be obtained.

According to the ultrasonic humidifier (a) having the above configuration, the blower (1
0) sucks the outside air through the intake port (8), and the air is accompanied by the mist generated by the ultrasonic transducer (7) through the mist guide tube (14) to the spray nozzle (b). It is blown out to the outside through the introduction path (20) and further through the blowout path (21) branched from the introduction path (20). And
Since a substantially hemispherical surface (22) having a diameter substantially the same as the inner diameter of the introduction passage (20) is formed in the branch passage of the outlet passage (21), the generated fog having a large particle diameter is not straight ahead. Since it is strong, almost all of the large particles collide with the above-mentioned approximately hemispherical surface (22) when entering the outlet path (21) from the introduction path (20), and as a result, the particle size of the generated fog is reduced. Large particles almost do not fall down as water droplets and are not blown out to the outside, and only small particles are sufficiently sorted and rectified along the approximately hemispherical surface (22) formed at the branch part. As a result, the water is blown out to the outside, water droplets are not generated due to collision of fogs with each other due to turbulent flow, and it is possible to sufficiently prevent the floor surface and the like from getting wet.

In the case of the embodiment shown in the drawings, the spray nozzle (b)
Although the mist guide tube (14) and the mist guide tube (14) are separately configured and connected to each other, they may be integrally formed in advance. Also,
In the embodiment shown in the drawings, the number of outlets (21) is two, but the number may be three or more.

In addition, even if the spray nozzle (b) is removed and the mist guide tube (14) is directly opened to the outside in the embodiment of the drawings, if the mist guide tube (14) is configured to be long, It is possible to prevent the generated mist having a large particle size from being blown to the outside to some extent. However, in that case, even if the mist guide tube (14) is rotatable, it collides with the adjacent mist guide tube (14) and its rotating motion is restricted, which makes the handling inconvenient or occurs. There is a problem that the amount of the mist having a small particle size is blown to the outside and the efficiency is deteriorated. On the other hand, in the embodiment of the drawings according to the present invention, the spray nozzle (b) is provided, and this works as described above. Therefore, the fog guide tube (14) should be made short. It can be installed externally instead of being built into the air conditioner. Even when the so-called direct-blowing type is used, the above-mentioned inconvenience does not occur.

[Effect of device]

According to the present invention, it is possible to sufficiently select only the small-sized particles of the generated fog and blow out only the small-sized particles to the outside, so that the floor surface etc. can be wetted more than the conventional humidifier. The effect that can be sufficiently prevented is obtained.
