Description

[Detailed Description of the Invention] The present invention relates to an improvement in a humidifier that performs humidification by blowing air through a humidifying member that has absorbed water.

This type of humidifier sucks water from a water tank into a water tank by rotating a water suction pipe that has a tapered cylindrical shape that gradually increases in diameter toward the top. The ejected water is supplied to a humidifying body installed to surround the water suction pipe to absorb water, and air is blown into the room by a blower blade through the humidifying body that has absorbed the water, thereby increasing the temperature inside the room. It performs humidification.

In this case, if a large number of ejection holes are formed throughout the peripheral wall of the water suction pipe, most of the water sucked in by the water suction pipe will be ejected from the ejection holes located at the bottom before reaching the upper part, and the humidifying body will be formed only at the lower part. There is a problem in that water is absorbed into the upper part of the tube, so there is a limit to the number of spout holes that can be formed on the peripheral wall of the water suction pipe.

For this reason, in the past, a small number of jet holes were formed on the peripheral wall of the water suction pipe, extending upward and downward, and water was jetted out from the upper and lower jet holes. Although water can be absorbed from the top and bottom of the body, due to the small number of ejection holes, water absorption becomes uneven in the humidifying unit body, making it impossible to achieve uniform water absorption over the entire area, resulting in poor humidification efficiency. was there.

The present invention was developed in view of the above circumstances, and its purpose is to provide a diffuser that diffuses water ejected from the ejection holes in the vicinity of a plurality of ejection holes extending above and below the water suction pipe, thereby achieving humidification. To provide a humidifier capable of uniformly absorbing water over the entire area of its body, thereby improving humidification efficiency.

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

Reference numeral 1 denotes a water storage tank in which water 2 is stored, and a container-shaped cover 3 with an open bottom surface is removably attached to the upper opening of the tank.

In this cover 3, an inlet 4 is formed in the lower part of the peripheral wall, a discharge port 5 is formed in the upper wall, and a wind guide 6 is provided protruding downward from the peripheral edge of the discharge port 5. has been done.

Reference numeral 7 denotes a drive monitor disposed within the air guide side 6 via a support arm 8, and its rotating shaft 7a is directed downward.

A blower blade 9 is fitted and fixed to the middle part of the rotation shaft 7a, and the upper end opening of the water suction pipe 10 is connected to the lower end thereof.

The water suction pipe 10 has a tapered cylindrical shape with a diameter that gradually increases from the lower end opening toward the upper end opening, and a plurality of pipes, for example, 5 The ejection holes 10a are formed at predetermined intervals from each other.

The lower end of this water suction pipe 10 is immersed in water 2 in the water storage tank 1.

Reference numeral 11 denotes a cylindrical humidifying body made of, for example, polyester urethane phonium, which has water absorbency and air permeability.

The humidifying body 11 is erected at the inner bottom of the water tank 1 so as to surround the water suction pipe 10, and its upper end is in contact with the lower end of the air guide cylinder 6.

Note that 12 is a grill attached to the discharge port 5 of the cover 3.

Now, 13 is the spout hole 10a in the peripheral wall of the water suction pipe 10.
This is a diffuser located near and attached by welding or gluing, etc., and this consists of five approximately semicircular diffusion portions 13a facing each jet hole 10a and a connecting strip connecting these diffusion portions 13a. It consists of part 13b.

Next, the operation of this embodiment having the above configuration will be explained.

When the drive motor 7 is energized, the rotation shaft 7a drives the blower blades 9 and the water suction pipe 10 in both directions.

Then, when the water suction pipe 10 is rotationally driven, the water suction pipe 10
sucks in water 2 from its lower end opening, pumps it up along the inner circumferential wall, and squirts it outward from the upper and lower jet holes 10a by centrifugal force.

The water jetted from the jetting hole 10a of this water suction pipe 10 is sent to the diffuser 1.
After colliding with the diffusion section 13a and the connecting strip section 13b at 3 and being diffused, the water is supplied to the humidifying section body 11 over the entire upper and lower regions and is absorbed therein.

- When the blower blade 9 is rotationally driven, the blower blade 9 sucks the air in the room 14 through the suction port 4 and through the humidifying body 11, and adds moisture to the air when passing through the humidifying body 11. After that, it is discharged from the discharge port 5 into the room 14, thereby humidifying the room 14.

In this case, the humidifying body 11 uniformly absorbs water over the entire upper and lower regions by the diffuser 18, so that the humidifying efficiency is improved.

Note that the present invention is not limited to the embodiments described above and shown in the drawings, and may be implemented with appropriate modifications within the scope of the gist, such as the number of jet holes in the peripheral wall of the water suction pipe being able to be set as appropriate. It is possible.

As is clear from the embodiments described above, in the present invention, a diffuser is provided near the spouting hole of the water suction pipe to diffuse water jetted from the spouting hole and supply it to the humidifying body. It is possible to provide a humidifier that allows the body to absorb water uniformly over the entire upper and lower regions, thereby improving humidification efficiency.
