Description

  The present invention relates to a humidifying device having good air humidification efficiency and capable of maintaining the efficiency for a long period of time.

  Conventionally, various types of humidifiers have been put to practical use. Among them, it is called a vaporization type that humidifies air by vaporizing the moisture of the water retaining material by applying air to the water retaining material that has absorbed water. There is something.

  Specifically, in the casing whose bottom is a water storage tank, a water retention material having water absorption is disposed in a state where the lower part is immersed in the storage water, and the casing is provided at the upper part of the water retention material. The air introduced into the inside is vaporized the moisture absorbed in the water retaining material, so that the air is supplemented with moisture, and the air humidified by supplementing the moisture is sent out to the outside of the casing.

  In such a humidifier, water is sucked into the water retention material by utilizing the capillary phenomenon, so that it is difficult to supply water to the upper portion of the water retention material, and the humidification efficiency is not good.

  As a humidifier that solves this problem, a water retention material is formed in a disk shape, and this disk-shaped water retention material is arranged so as to rotate in an upright state. It is provided at a height that can be rotated in a state where And the thing which vaporizes the water | moisture content absorbed by applying the introduce | transduced air on the upper part of a water retention material is proposed. As a result, the portion that is exposed to air, that is, the upper portion of the water retaining material is well moistened, so the humidification efficiency is improved.

  The filter case 7 assembled in this manner contains a water retaining material 8 in a state of being held by a holding portion 9d of the first part 9, and the outer peripheral portion includes a side plate 9a of the first part 9 and the side plate 9a. The groove part 11 which consists of the side plate 10a of the 2nd part 10 and the protrusion part 10c is in the state provided in the perimeter. A water passage hole 10e is formed between the blade 10d and the blade 10d at the bottom of the groove 11, that is, the protruding portion 10c (FIG. 3 (a), which is a partially enlarged view of portion A in FIG. 1). reference). As shown in FIG. 3B, the water passage hole 10 e is formed in a long hole shape that is long in a direction inclined clockwise from the circumferential direction of the filter case 7.

  On the other hand, the upper lid 4 is formed in a rectangular plate shape larger than the opening portion of the casing 2, and a convex portion 4 a continuously provided on the outer peripheral portion of the lower surface is fitted into the opening portion of the casing 2 and attached. ing.

  The lower surface of the upper lid 4 is formed wider than the interval between the guide plates 2b of the casing 2, and a partition plate 4b parallel to the guide plate 2b is provided so that both sides thereof are along the guide plate 2b. It has been.

  The partition plate 4b has an annular seal portion 4c that has a diameter similar to that of the vaporization filter 3 on the surface with respect to the vaporization filter 3 and is projected so as to reach the vicinity of the vaporization filter 3. A flow hole 4d is formed at a position corresponding to the air inlet 2a in a portion located inside the seal portion 4c. The partition plate 4 b is formed with a dimension shorter than the height of the casing 2, and a gap s is provided between the lower end of the partition plate 4 b and the bottom surface of the casing 2.

  The upper lid 4 has a circular outlet 4e formed in a portion facing the space 21 on the side opposite to the side where the vaporizing filter 3 is disposed, inside the casing partitioned by the partition plate 4b. The fan mounting portion 4f provided with a locking portion is formed by projecting the edge of the outlet 4e downward and projecting the inner peripheral surface of the tip portion inward.

  A fan 12 that performs intake and blowing of humidified air is fitted into the fan mounting portion 4f, and the air outlet 4e is covered with an air outlet cover 13 in which a photocatalyst is adsorbed on a nonwoven fabric.

  Furthermore, a small-diameter through hole is formed in the vicinity of the discharge port 4e, and a water supply pipe 14 is inserted. The water supply pipe 14 includes a cap 14a that can be attached and detached at the upper end, passes through the hole 2d of the intermediate plate 2c in the casing 2, and the lower end portion is positioned near the bottom surface of the casing 2, so that the upper lid 4 It is supported.

  Next, the operation of the humidifier 1 will be described. In addition, the flow (flow path) of the air in the casing 2 is shown with the dashed-two dotted line.

  The cap 14 a of the water supply pipe 14 is removed and water is supplied into the casing 2. The supplied water flows down the water supply pipe 14 and flows into the lower space 22 among the spaces 21 and 22 that are vertically partitioned by the middle plate 2 c inside the casing 2.

  Since the space 22 and the space 23 in which the vaporization filter 3 is provided can be circulated in the gap s below the partition plate 4 b, the water supplied to the space 22 flows into the space 23. Then, when the water level is such that about 1/3 of the vaporizing filter 3 is immersed in water, the water supply is stopped, and the cap 14a of the water supply pipe 14 is attached and covered.

  Next, the motor 5 is driven to rotate the vaporization filter 3 at a slow speed of 3 to 6 rpm, and the fan 12 of the upper lid 4 is rotated. When the fan 12 is rotated, the air inside the casing is sent to the outside from the air outlet 4e, and the inside of the casing 2 becomes negative pressure. As a result, external air is sucked into the casing 2 from the air inlet 2a. Thus, the air introduced into the casing passes through the sterilization filter 6 so that various germs are removed.

  The air introduced into the space 23 from the intake port 2a passes through the vaporization filter 3 and flows into the space 21 from the circulation hole 4d through the seal portion 4c of the partition plate 4b.

  At this time, the air passing through the vaporization filter 3 enters the filter case from the vent hole 9e of the first part 9, passes through the water retaining material 8 in the filter case, and then passes through the vent hole 10f of the second part 10 to the filter. Although it flows out of the case 7, when passing through the water retaining material 8, the moisture of the water retaining material 8 is vaporized, and the vaporized water is supplemented to be humidified.

  At this time, since the air holes 9e of the first part 9 are provided so as to correspond to the portions near the outer periphery of the water retaining material 8 in a state containing more water, the air holes 9e are efficiently humidified.

  As the filter case 7 rotates, the lower portion of the water retaining material 8 is not only sequentially immersed in the stored water and supplied with water, but also when the filter case 7 rotates, it is pumped up by the blade 10d. The supplied water is also supplied by sequentially flowing into the filter case 7 from the water passage hole 10e as the blade 10d rises. Thus, water is sufficiently supplied to the water retaining material 8.

  Further, since the water passage hole 10e is formed in an elongated shape extending in a direction slightly shifted clockwise from the rotation direction of the filter case 7, the water pumped up by the blade 10d is twisted from the outer peripheral surface of the water retaining material 8. It can be supplied to a wide range. Thereby, the whole water retention material 8 can be moistened more uniformly.

  In this way, after the moisture supplemented and humidified air flows into the space 21, it is sent out from the outlet 4e of the casing 2 to the outside by the fan 12. At this time, the sterilization filter 13 of the outlet 4e is removed. Since germs are removed by passing, clean humid air can be sent out to the outside.

  In this way, the indoor air is circulated through the humidifier 1 to prevent the indoor air from being dried and to maintain a clean state.

  Then, the humidifier 1 can pump the stored water with the blades 10d of the filter case 7 even when the water level of the stored water decreases and becomes lower than the water retention material 8, so that water can be added for a longer period of time. Can be used without.

  In addition, by providing the air inlet cover 6 having a sterilizing action at the air inlet 2a, the introduced air is sterilized, and it is difficult for bacteria to propagate in the casing, thereby keeping the inside of the casing 2 more clean. it can. On the other hand, since the blower outlet 4e is also provided with the blower outlet cover 13 having a sterilizing action, it is possible to prevent germs that have entered the casing 2 from being mixed with humidified air and sent to the outside.

  The humidifying device 1 can also be used as a deodorizing device by adding a deodorizing liquid instead of water. When used as a deodorizing device, the air introduced into the casing 2 from the intake port 2a comes into contact with the deodorizing liquid absorbed in the water retaining material 8 when passing through the vaporizing filter 3, and is contained in the air. The odor component is adsorbed by the deodorizing liquid, whereby the odor component and air are separated. In this way, the air from which the odor component has been removed and no strange odor is removed is sterilized by the air outlet cover 13 of the air outlet 4e and sent out of the casing 2. Specifically, it can be used as an odor remover for cigarettes and pets.

  The humidifier 1 can prevent the water from jumping up due to vibration or the like by the partition plate 4b and the middle plate 2c, so that it can be used safely in vehicles such as cars, and it is safe because it is vaporized and does not involve heat. It can also be used in hospitals, nursing homes, restaurants, entertainment facilities, restaurants, refrigerators, food storage, and the like. If the water storage water is kept indoors, it can effectively deodorize odors such as cigarettes, pets, and yakiniku, and the air outlet cover 13 can remove germs contained in the air. Therefore, the room can be kept clean and comfortable.
