Description

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

Conventional humidifiers of this type have a so-called double-shaft drive motor with a rotating shaft that protrudes up and down inside an air guide tube installed in the upper part of the water tank, and a water-absorbing motor is installed at the bottom of the air guide tube. The upper part of a cylindrical humidifying body having a cylindrical body is connected, and the lower part of this humidifying body is immersed in the water in the water tank, and when rotated by the lower part of the rotating shaft of the drive motor, the water in the water tank is immersed. A suction pipe is attached to the upper part of the rotation shaft of the drive motor that sucks up water and splashes it onto the humidifying body. There is a structure equipped with a blower blade that discharges air into the room.

However, in the above-mentioned conventional configuration, if the distance between the drive motor and the suction pipe is made small, the water splashed from the suction pipe onto the humidifying body will directly fall on the lower part of the drive motor, so there are problems with the insulation of the drive motor. This is unfavorable in terms of rust, and if the distance between the drive motor and the suction pipe is large, the overall size will increase.

The present invention was made in view of the above circumstances, and its purpose is to arrange a drive motor in a wind guide tube at the upper part of a water storage tank so that its rotating shaft is directed downward, and to A cylindrical humidifying body having water absorption properties is connected to the lower part of the humidifying body, and
A blower blade is provided, which has a substantially bottomed cylindrical boss portion attached to the rotating shaft of the drive motor so as to surround at least a lower portion of the drive motor, and blows air to the outside through the humidifying body when driven to rotate. and by providing a rotating body located below the blower blade, which is attached to the rotating shaft of the drive motor and splashes water in the water tank onto the humidifying body when driven to rotate. , it is possible to achieve miniaturization without causing problems with insulation and rusting,
Moreover, it is an object of the present invention to provide a humidifier that can be manufactured at low cost without the need to use a double-shaft type drive motor.

By placing it inside the upper half 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 into a cylindrical shape using 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 wind guiding tube 3 via a support arm 8 so that the rotating shaft 7a is directed downward, and an engaging pin 9 is provided at the protruding base of the rotating shaft 7a so as to be orthogonal thereto.
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 as a rotating body, which is a long tapered cylinder whose diameter decreases as it goes downwards, with an opening on its lower surface serving as a suction port 15a, and a number of splash holes on the peripheral wall. 15b is formed.

Furthermore, a fixture 17 having a threaded portion 16 in the center is fitted and fixed into the upper opening of the suction pipe 15.

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 boss 12 is connected to the lower part of the drive motor 7. After that, the threaded part 16 of the fixture 17 of the suction pipe 15 is screwed onto the threaded part 10 of the rotating shaft 7a, and the blowing blade 11 and the blowing blade 1 are attached to the rotating shaft 7a.
1, and the suction pipe 15 is attached so as to be able to rotate integrally therewith.

In this case, the suction pipe 15 is located in the middle part of the filter 6, and its lower end is immersed in the water in the water tank 2.

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 into the water tank 2 to a predetermined water level, for example, water level A in FIG. Water penetrates.

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 the water in the water storage tank 2, and the centrifugal force accompanying the rotation causes water to flow into the suction pipe 15.
The filter 6 is sucked in through the suction port 15a and rises along the tapered inner circumferential wall, and further flows through the splash hole 15b.
water is splashed onto the exposed parts of the water to absorb moisture.

The air sucked in from the intake port 1a as the blower blade 11 rotates passes through the portion of the filter 6 exposed from the water, is humidified, and further passes through the air guide tube 3 and upwards from the jet port 3b. Air is blown to the outside, that is, indoor B, and therefore indoor B
Humidification operation is performed while circulating the air.

In this case, since the boss portion 12 of the blower blade 11 surrounds the lower part of the drive motor 7, the water splashed onto the filter 6 from the splash hole 15b of the suction pipe 15 is directly directed to the lower part of the drive motor 7. It doesn't cost anything.
