Description

[Detailed Description of the Invention] The present invention relates to an improvement of a humidifier that humidifies a room by ventilating a humidifying body that has absorbed water.

Conventional humidifiers of this type splash water in the water tank onto a filter, which is a water-permeable humidifying unit, arranged in the water tank, using a water suction pipe rotated by a drive motor, and absorb the water. This structure humidifies the room by blowing air through a filter with a blower blade, and therefore humidification is performed only by the contact between the water absorbed by the filter and the wind passing through the filter, which has the problem of poor humidifying effect.

The present invention was developed in view of the above circumstances, and its purpose is to cause the water in the water storage tank to be sucked into the air blower blades that blow air through the humidifying body that has water absorption properties, and to cause the water to be scattered outward by the suction pipe. By having a structure in which at least a part of the water is splashed, a humidified wind is sent through a humidifying unit that absorbs water into the room, and a mist water formed by being crushed by a blowing blade is sent together with this wind. It is an object of the present invention to provide a humidifier that can humidify the room and improve the humidifying effect.

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

Reference numeral 1 denotes an outer box with an open top surface, an opening provided in the upper peripheral wall to serve as an intake port 1a, and a lower portion forming a water storage tank 2.

Reference numeral 3 designates a cylindrical wind guide tube with open upper and lower surfaces, and a flange portion 3a pointing outward is bent at the edge of the upper surface opening, and this flange portion 3a is connected to the outer box 1. It is installed in the upper part of the outer box 1 by placing it on the upper opening edge of the outer box 1.

The upper surface opening of this wind guide tube 3 is defined as a spout 3b.

Reference numeral 6 denotes a filter serving as a humidifying body, which is reinforced by attaching a wire mesh 5 to the inner surface of a water absorbing member 4 formed in a cylindrical shape from polyester urethane foam, and this filter is attached to the lower opening of the air guide tube 3 to the water absorbing member 4. 4 and the wire mesh 5 are connected so as to be sandwiched at their upper ends, and their lower portions are extended downward so as to be immersed in the water in the water storage tank 2.

Reference numeral 7 denotes a drive motor disposed within the air guide tube 3 via a support arm 8 so that the rotating shaft 7a is directed downward.
is provided protrudingly, and a threaded portion 10 is formed at the tip.

Reference numeral 11 denotes a blower blade whose inner diameter is the same as that of the drive motor 7.
The boss portion 12 has a configuration in which a plurality of wing pieces 13 are protruded from the outer periphery of the boss portion 12, which has a substantially bottomed cylindrical shape and is slightly larger than the outer diameter of the boss portion 12.
A short cylindrical shaft hole 12a is formed in the center of the shaft hole 12a, and an engagement groove 14 extending in the radial direction is formed in the upper end surface of the shaft hole 12a.

Reference numeral 15 denotes a suction pipe, which has a long tapered cylindrical shape whose diameter decreases as it goes downwards, and its lower end, or lower surface opening, serves as the suction port 15 a, and its upper end, or upper surface opening, serves as the suction port 15 a. Splash opening 15 that gradually expands as it goes toward
b, and the inner surface of the splash opening 15b, which faces diagonally upward, is a guide surface 15C.

16 is a fixture having a threaded portion 16a in the center;
Apply this to the splash port 15b of the suction pipe 15 on its guide surface 15.
It is fixed with screws 17 so as to be at a predetermined distance from C.

Then, by fitting the shaft hole 12a of the blower blade 11 into the rotating shaft 7a of the drive motor 7 and engaging the engagement groove 14 with the engagement pin 9, the lower part of the drive motor 7 is moved by the boss 12. After surrounding and holding the suction pipe 15, the threaded part 16a of the fixture 16 is screwed onto the threaded part 10 of the rotating shaft 7a, and the blower blade 11 and the lower part of the blower blade 11 are attached to the rotating shaft 7a. At this position, the suction pipe 15 is attached so as to be integrally rotatable.

In this case, the suction pipe 15 is located at the center of the filter 6, and its lower end is immersed in the water in the water tank 2, and its guide surface 15C is located at the center of the filter 6. It is designed to point in 13 directions.

In addition, 18 and 19 in the figure are the intake port 1a and the jet port 3b.
These are grilles installed on each side to allow ventilation.

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

Now, when water is supplied to the water storage tank 2 to a predetermined water level, for example, water level A, approximately the lower half of the filter 6 is immersed in water, and the iron water also permeates into the upper half of the filter 6 due to capillary action or the like. .

Thereafter, when the drive motor 7 is energized, the rotating shaft 7a rotates the blower blades 11 and the suction pipe 15.

The lower part of this suction pipe 15 is immersed in water in the water storage tank 2, and water is sucked in from the suction port 15a of the suction pipe 15 and rises along the tapered inner circumferential wall due to the centrifugal force caused by rotation. In addition, the guide surface 1 of the splash opening 15b
5C and scattered outward, and most of the scattered water splashes onto the blades 13 of the blower blades 11, part of which is crushed and atomized, and the rest splashes onto the top of the filter 6. water is absorbed.

The air sucked from the intake port 1a as the blower blade 11 rotates passes through the exposed portion of the filter 6 from the water and comes into contact with the water absorbed by the filter 6, becoming humid. Together with the mist water in the vicinity of 11, it passes through the air guide pipe 3 and is discharged upward from the jet port 3b to the outside, that is, into the room B, thereby performing humidification operation while circulating the air in the room B.

In this way, according to this embodiment, the rotation shaft 7 of the drive motor 7
Attach the blower blade 11 to a and
The suction pipe 1 is installed below the suction pipe 15, and the water sucked in through the suction port 15a of the suction pipe 15 is splashed outward from the splash port 15b, and the scattered water is transferred to the blade 13 of the blower blade 11.
A part of it is pulverized and atomized, and the rest is splashed onto the upper part of the filter 6 to absorb water, and it passes through the filter 6 into the chamber B along with the humid air. The pulverized mist water is sent by the air blowing blades 11, and the humidification effect can be significantly improved compared to the conventional method.

Moreover, according to this embodiment, the boss portion 12 of the blower blade 11
Since the lower part of the drive motor 7 is surrounded by the blades 13 of the air blower blades 11, even if splashed water from the suction pipe 15 is splashed and a part of it is pulverized, the splashed water will not reach the drive motor 7. There is no direct contact with the lower part of the drive motor 7, and there are no problems with the insulation or rust of the drive motor 7.

Furthermore, according to this embodiment, since the blower blade 11 is used to atomize a part of the splashed water from the suction pipe 15, for example, a special spray for atomizing the splashed water is used. There is no need to provide a generator, and the configuration does not become complicated or large.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings, but can of course be implemented with appropriate modifications within the scope of the invention.

As is clear from the above-described embodiments, the present invention improves the humidification effect by sending atomized water, which is pulverized and formed by the blower blades, into the room together with the humid air carried by the humidifying unit. In addition, it is possible to provide a humidifier that has excellent practical effects in that it is not necessary to provide a dedicated spray generator, and the structure does not become complicated or large.
