Description

[Detailed description of the invention] (b) Industrial application fields This invention relates to an ultrasonic humidifier.

(b) Conventional technology A conventional ultrasonic humidifier is, for example,
As disclosed in Japanese Patent No. 25426, a humidifier in which a mist outlet is integrally formed on the upper side of the humidifier body is known. This has the advantage of being compact in packaging because the mist outlet does not protrude upward from the humidifier body.

(c) Problems to be Solved by the Invention) However, the above-mentioned ultrasonic humidifier has drawbacks such as being inconvenient to use and unable to clean the aquarium because the direction of the mist is fixed.

This invention has been made in view of the above-mentioned facts, and an object of the present invention is to enable selection of the direction in which the mist is blown and to facilitate cleaning of the inside of the aquarium.

(d) Means for Solving the Problems This invention includes a water tank having an ultrasonic vibrator at the bottom and an opening at the top, and a water tank that is penetrated vertically through the water tank and has an air outlet facing above the tank. A blower tube and
A mist guide tube is inserted into the water tank through an opening to cover the blower tube and the ultrasonic vibrator, and the upper part has an air outlet integrally, and the lower part is inserted into the water tank through the opening and is externally fitted into the mist guide tube. The configuration includes a blow-off tube.

Further, in the present invention, a step portion is formed at the lower part of the mist guiding cylinder to come into contact with the lower part of the blowing cylinder.

(*) Effect With this configuration, the blow-off pipe can be attached to and removed from the water tank, so it is possible to change the direction of the blow-off port and select the direction in which the mist is blown out. Also,
Since the blower tube is covered by the mist guide tube, there is no fear that water droplets attached to the blower tube will enter the blower tube from the blower port when changing the direction of the blower outlet. Furthermore, since the blow-off tube and the mist-guiding tube are removable, the inside of the water tank, especially the ultrasonic vibrator, can be easily cleaned.

By forming a stepped part at the bottom of the mist guide tube that comes into contact with the lower part of the blowout tube, even if the mist guide tube is installed in an inclined position, the mist can be guided by pushing the blowout tube into the water tank. The tube is regulated in the correct position.

(F) Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In FIGS. 1 to 7, reference numeral 1 denotes a humidifier main body in which a water tank 3 and a machine room 4 are vertically divided in a main body case 2, and has a substantially rectangular parallelepiped shape with a substantially square bottom surface. Further, the upper surface of the main body case 2 is covered with a removable lid 5 so that the water tank 3 can be easily cleaned. On this lid body 5, there is a rectangular blow-off cylinder 7 having a blow-out port 6 on its chamfered upper side, and three rectangular water tanks 8, 8, 8 arranged in an L-shape in a substantially rectangular parallelepiped shape. They are placed side by side.

As shown in FIG. 4, the lid body 5 has three insertion openings: a substantially square insertion opening 9 for inserting the lower part 7A of the blow-off cylinder 7, and a water supply opening 8A at the lower part of the water tank 8. 10, 10, 10, and an insertion port 1
Guide tubes 10 are provided on the outer peripheries of 0, 10, and 10, respectively.
A, 10A, 10A are hanging down. In addition, there are three notches 9A, 9A, 9A on the periphery of the insertion port 9.
As shown in FIG. 5, the lower part 7A of the blow-off tube 7 is provided with two protrusions 7B, which can be fitted into the notches.
7B is provided.

The water tanks 8 are made of transparent glass, and each
As shown in the figure, the water supply port 8A covered with the valved cap 11 is connected to the insertion port 10 of the lid 5 and the guide tube 10.
A is inserted into the water tank 3 through the water tank 8, and the water in the water tank 8 is replenished into the water tank 3 by pushing the valve cap 12 by the protrusion 12 at the bottom of the water tank 3.

As shown in FIG. 1, the blow-off tube 7 has a lower portion 7A inserted into the water tank 3 through the insertion opening 9 of the lid 5.
During this insertion, the ridges 7B, 7B and the cutouts 9A, 9A, 9A of the insertion port 9 restrict the outlet 6 to face in two directions, front or left. There is no need to worry about it being accidentally directed towards tank 8. A blower tube 13 is vertically installed on the bottom wall 3A of the water tank 3 and extends vertically through the tank 3, and an air outlet 13A is provided in the upper part of the blower tube 13. This blower tube 13
This is for discharging air sent by a blower (not shown) in the machine room 4 into the atomizing cylinder 7A from the air outlet 13A. Further, an ultrasonic vibrator 14 is attached to the bottom wall of the water tank 3 obliquely toward the inside of the blow-off cylinder 7 . This is to make effective use of the inside of the water tank 3. Reference numeral 15 denotes a mist guiding tube that guides the mist generated by the ultrasonic vibrator 14 and the air discharged from the air outlet 13A to the upper part of the blowing tube 7 above the water tank 3. The mist guide tube 15 is inserted into the water tank 3 through the insertion port 9 of the lid 5, surrounds the blower tube 13, and covers the upper part of the ultrasonic vibrator 14. The mist guide cylinder 15 is provided with a partition 15A so as to block the front side of the air outlet 13A. This partition 1
5A is for smoothly guiding the falling water from the water column 16 to the water surface and preventing the falling water from entering the air outlet 13A.
It also serves as a blower guide that directs the air discharged from the tank near the water surface. Furthermore, stepped portions 15B and 15C are integrally formed at the lower part of the mist guide tube 15 and come into contact with the lower end of the blowout tube 7 that is fitted onto the mist guide tube 15. Further, a draining plate 16 is suspended from the bottom wall 3A between the blower tube 13 and the ultrasonic vibrator 14. This drain plate 16 is used to prevent the water droplets from falling on the vibrator unit 17 and other electrical components when the fog grows and becomes water droplets in the blower tube 13. It has a larger height dimension than the oscillator unit 7, and is also used for positioning the vibrator unit 7.

In addition, 18 is a push button type operation switch, and the 7th
As shown in the figure, it is held by a switch mounting bracket 19 screwed to the lower surface of the bottom wall 3A of the water tank 3. Further, the operation knob 18A of the operation switch 18 is exposed on the front surface of the main body case 2. Further, the switch mounting fitting 19 is L-shaped in plan view and also serves as a mounting fitting for the transformer 20. In this way, by mounting the transformer 20 with the mounting flange 20A vertically, the installation space of the transformer 20 in the machine room 4 can be reduced compared to the case where the transformer 20 is directly mounted on the lower surface of the bottom wall 3A. Also,
In addition to improving the heat dissipation of the transformer 20, the mounting bracket 19 also serves as a magnetic shield plate, and the transformer 2
There is no fear that a zero magnetic field will adversely affect other electrical components.

According to this embodiment, since the blow-off tube 7 is detachable from the water tank 3, the direction of the blow-off port 6 can be changed to select the direction in which the mist is blown out (two directions in this embodiment). Moreover, since the blower tube 13 is covered by the mist guide tube 15, when changing the direction of the blower outlet 6, water droplets attached to the inner wall of the blower tube 15 are prevented from entering the blower tube 13A from the blower outlet 13A. can be prevented. In addition, the blowout tube 7 and the mist guide tube 1
5 are both removable from the aquarium 3,
White powder adhering to the ultrasonic vibrator 14 in the water tank 3 can be easily removed. Furthermore,
The lower end of the blowout tube 7 is connected to the stepped portion 15B, 1 of the mist guide tube 15.
5C, the inclination of the mist guiding tube 15 can be corrected when the blowing tube 7 is inserted into the water tank 3, and the mist generated in the water tank can be smoothly guided to the blowing outlet 6. I can do it.

(G) Effects of the invention Since this invention is configured as described above,
It has the following effects.

Since the blow-off tube is removable from the water tank,
You can change the direction of the air outlet and select the direction in which the mist is blown out, making it easy to use.

Since the blowout tube and the mist guide tube are detachable from the water tank, the inside of the water tank can be easily cleaned by removing them.

Since the blower tube is covered by the mist guide tube,
When changing the direction of the blower, water droplets attached to the blower can be prevented from entering the blower.
