(Embodiment 1)
As shown in FIGS. 1 and 2, the humidifying unit 1 is provided with a rectangular humidifying filter 3 on a humidifying water storage tank 2 for storing humidified water. The humidifying filter 3 is located above the water storage surface of the humidifying water storage tank 2, and the entire surface of the humidifying filter 3 comes into contact with the air, so that the humidifying filter 3 can be humidified from the entire surface.

  An intermediate water storage tank 6 is provided between the upper end 4 and the lower end 5 in the vertical direction of the humidifying filter 3, that is, in the height direction. The intermediate water storage tank 6 is provided substantially full width of the humidification filter 3. A water wheel 7 is provided in the humidified water storage tank 2, the water wheel 7 is rotated by a water wheel drive motor 8, the humidified water stored in the humidified water storage tank 2 is pumped up, and the humidified water is supplied to the intermediate water storage tank 6.

  The intermediate water storage tank 6 is provided on the front surface 9 on the side surface of the humidifying filter 3, and stores humid water between the side wall 10 of the intermediate water storage tank 6 and the front surface 9 on the side surface of the humidifying filter 3. The humidified water supplied to the intermediate water storage tank 6 contacts the humidifying filter 3 and is absorbed by the humidifying filter 3.

  An opening 12 is provided in the bottom 11 of the intermediate water tank 6. The humidified water stored from the opening 12 is supplied to the humidifying filter 3. The water supply to the humidification filter 3 is supplied and supplied to the lower end of the humidification filter 3 by the gravity effect and the water absorption effect of the humidification filter 3.

  The vertical direction of the humidification filter 3 of the intermediate water storage tank 6, that is, the position in the height direction is only required to absorb and supply water up to the upper end 4 of the humidification filter 3 due to the water absorption effect of the humidification filter 3.

  The position of the intermediate water storage tank 6 provided between the upper end 4 and the lower end 5 in the vertical direction of the humidifying filter 3 is a position capable of absorbing water up to the upper end 4 of the humidifying filter 3. It is sufficient if water is absorbed at a rate higher than the vaporization rate from the water and can be supplied.

  For example, the position capable of absorbing water up to the upper end 4 of the humidifying filter 3 is approximately 70% to 90% of the water absorption height at which the humidifying filter 3 can absorb water. Assuming that the maximum water absorption height that the humidifying filter 3 can absorb water is 150 mmH, the position of the intermediate water storage tank 6 is provided below the upper end 4 of the humidifying filter 3 by about 105 mm to 135 mm of 150 mm × 70% to 90%.

  Moreover, the vertical direction of the humidification filter 3 of the intermediate water storage tank 6, that is, the position in the height direction may be sufficient to supply water up to the lower end 5 of the humidification filter 3 by the gravity effect and the water absorption effect of the humidification filter 3. What is necessary is just to be able to supply evenly and uniformly over the entire surface of the humidifying filter 3.

  When the humidifying filter 3 is, for example, 320 mmH × 250 mmW × 10 mmD, the vertical position of the humidifying filter 3 of the intermediate water tank 6 is, for example, approximately 120 mm below the upper end 4 of the humidifying filter 3, and the lower end of the humidifying filter 3 It is about 200 mm above from 5. The humidification filter has water absorption.

  The intermediate water tank 6 is, for example, 10 mmH × 250 mmW × 15 mmD, and the opening 12 at the bottom 11 of the intermediate water tank 6 is approximately equal to the width of 250 mmW of the intermediate water tank 6, approximately 10 mm × 4-5. Provide. The intermediate water tank 6 has strength and moldability, and is, for example, a resin such as PS or ABS.

  The water wheel 7 has a diameter of 120 mm, for example, and is rotated by the timing motor 13 at about 4 rpm. The water wheel 7 is provided with approximately 20 to 30 cc / piece × 6 water supply containers 14 equally, and the rotation by the timing motor 13 pumps up the humidified water stored in the humidification water storage tank 2 with the water supply container 14. Humidified water is supplied from the water supply container 14 to the intermediate water tank 6 and supplied.

  Examples of the material of the water wheel 7 include resins such as PS and ABS.

  In the above configuration, the water in the humidified water storage tank 2 is pumped up and supplied to the intermediate water storage tank 6 of the humidifying filter 3 provided on the humidifying water storage tank 2 for storing the humidified water by the rotation of the water wheel 7.

  The humidified water supplied to and stored in the intermediate water storage tank 6 is obtained by absorbing water from the humidifying filter 3 above the intermediate water storage tank 6 of the humidifying filter 3, and by gravity supply water and humidifying below the intermediate water storage tank 6 of the humidifying filter 3. Due to the water absorption action of the filter 3, the water supply to the humidifying filter 3 is hardly uneven, and the humidifying filter 3 is evenly supplied with water.

  Since it becomes easy to uniformly supply water to the humidifying filter 3 without unevenness, humidification from the entire surface of the humidifying filter 3 becomes possible, and humidification can be efficiently performed.

  Further, when the position of the intermediate water storage tank 6 provided between the upper end 4 and the lower end 5 in the vertical direction of the humidifying filter 3 is set to a position where water can be absorbed up to the upper end of the humidifying filter 3, the humidifying filter 3 supplies water more evenly. As a result, humidification from the entire surface of the humidification filter 3 becomes possible, and humidification can be performed efficiently.

  In addition, by setting the position of the intermediate water storage tank 6 provided between the upper end 4 and the lower end 5 in the vertical direction of the humidifying filter 3 to a position where water can be absorbed up to the upper end 4 of the humidifying filter 3, the humidifying filter is removed from the intermediate water storage tank 6. Therefore, the humidification filter 3 can be made higher than the water supply from the upper end 4 by the height that can absorb water up to the upper end 4 of 3, so that the installation area can be reduced and a slim humidification unit can be provided.

  When the air is blown to the humidifying filter 3 supplied by a blower (not shown) as a blowing means for blowing air, vaporization progresses, the humidifying ability is improved, and rapid humidification is possible. At that time, if the water turbine 7 is provided on the downstream side of the humidifying filter 3, the pressure loss is lower and better than that provided on the upstream side.

  For example, if the air volume by the blower is set to three stages of strong, medium and weak, the strength is 7 m 3 / min, the medium is 4 m 3 / min, and the weak is 1.8 m 3 / min, humidification according to the necessity of humidification becomes possible.

  According to the present embodiment, by supplying water to the humidifying filter 3 using water turbine 7, the humidifying unit 1 with low noise and good maintainability can be provided.

  Further, the intermediate water storage tank 6 is positioned so as to be able to absorb water up to the upper end 4 of the humidifying filter 3, the upper part of the intermediate water storage tank 6 is due to the water absorption action of the humidifying filter 3, and the lower part of the intermediate water storage tank 6 is the gravity water supply. Due to the water absorbing action of the humidifying filter 3, it is difficult to cause unevenness in the supply of water to the humidifying filter 3, and the humidifying unit 1 with high humidifying efficiency can be provided.

  When humidifying water is supplied from the upper end of the humidifying filter, from above, even if the humidifying filter absorbs water, depending on the height of the humidifying filter, the supplied humidified water can easily be supplied to the humidifying filter and unevenly supplied. It is difficult to reach the lower end of the humidifying filter, and it becomes difficult to uniformly supply water to the entire surface of the humidifying filter, making it difficult to efficiently humidify.

  When the intermediate water storage tank 6 for storing the humidified water is provided between the upper end 4 and the lower end 5 in the vertical direction of the humidifying filter 3 as in the present embodiment, the upper side of the intermediate water storing tank 6 is due to the water absorption action of the humidifying filter 3. Moreover, the water supply to the humidification filter 3 becomes easy uniformly by the gravity water supply and the water absorption action of the humidification filter 3 below the intermediate water storage tank 6, and the humidification unit 1 with high humidification efficiency can be provided.

  Furthermore, when the position of the intermediate water storage tank 6 provided between the upper end 4 and the lower end 5 in the vertical direction of the humidifying filter 3 is a position capable of absorbing water up to the upper end of the humidifying filter 3, the humidifying filter 3 is located above the intermediate water storage tank 6. Due to the water absorption action, and below the intermediate water storage tank 6, due to the gravity water supply and the water absorption action of the humidification filter 3, the water supply to the humidification filter 3 is likely to be uniform, and the humidification efficiency is improved.

  In addition, when the humidifying filter 3 is rectangular or the horizontal direction is an arc shape, a free shape can be formed according to the outer frame of the humidifying filter 3 and the outer shape of the case, and the outer frame and the case can be kept compact. The degree of freedom of shape design and design will be improved.

  For example, even if the outer frame is sloped or stepped, the upper end of the rectangular or arcuate humidifying filter can be sloped or stepped to match the slope of the outer frame or the stairs. It becomes an outer frame that incorporates the humidifying filter 3.

  As shown in FIG. 3, the example which applied the humidification unit 1 of a present Example to the humidification air cleaner 21 is demonstrated. The humidified air purifier 21 includes a humidified air cleaner inlet 22, a filter for removing dust in the air such as a high performance filter and a HEPA filter, a humidifier unit 1, and a humidified air cleaner outlet 24.

  By purifying the air sucked from the humidified air cleaner inlet 22 with the filter 23, humidifying the purified air purified by the humidifying unit 1, and blowing the humidified humidified purified air from the humidified air cleaner outlet 24, It is possible to provide a humidified air purifier with low noise, good maintainability, less unevenness in the supply of water to the humidification filter 3, and good humidification efficiency.

  The humidification unit according to the present invention has low noise, good maintainability, good humidification efficiency, and excellent compactness. Therefore, a humidifier, a humidified air purifier, a heater, or an air conditioner with a built-in humidification function is used. It is useful as a humidifying unit used in a machine.
