Description

The present invention relates to a humidifying device that humidifies by supplying water from the upper part of a humidifying filter mounted on a main body case.

The conventional humidifying device includes a water storage container provided at the bottom for storing water, and a humidifying filter arranged above the water storage container and immersing the entire lower end in the water of the water storage container. The humidifying filter sucks up the water in the water storage container by capillarity and is in a state of retaining water. When air is blown to the humidifying filter that retains water by the air blowing unit, it becomes humidified air, and the humidified air is blown into the room from the humidifying device to humidify the room.

Japanese Unexamined Patent Publication No. 2005-274097

The humidifying filter of such a conventional humidifying device is designed so that water easily permeates in the vertical direction because water must be sucked upward from a water storage container provided at the bottom.

However, when such a humidifying filter is used in a humidifying device that supplies water from above the humidifying filter, the humidifying filter easily permeates water in the vertical direction, so that the water supplied from above can be used. Water hardly permeates in the lateral direction, and water flows downward as it is. In particular, as shown in FIG. 7, when water is supplied from above the humidifying filter 101, water supply ports 100a to d to the humidifying filter above are provided at predetermined intervals in the lateral direction. Water permeates downward (arrows 102a to d) with respect to the water supply port 100, but it is difficult for water to permeate in the lateral direction. It takes a long time for water to penetrate. In particular, water does not permeate into 103A to 103E near the water supply port 100. Therefore, it takes a long time for the entire humidifying filter 101 to be in a water-retaining state. Therefore, until the entire humidifying filter is in a water-retaining state, air may be blown into the room through a portion where the water is not retained, which has a problem that the amount of humidification is reduced.

Therefore, the present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a humidifying device that can quickly retain water in the entire humidifying filter in a humidifying device that supplies water from above the humidifying filter. And.

In order to achieve this object, the present invention comprises a main body case having a suction port and an air outlet, a water storage container for storing water in the main body case, a humidifying filter for retaining water, and the humidifying filter. A supply unit that supplies water to the humidifying filter, a pump unit that sends water in the water storage container to the supply unit, and an air outside the main body case are sucked from the suction port, and the humidifying filter is used. The supply unit includes a blower unit that blows out from the air outlet through the air outlet, and the supply unit includes a water storage portion that stores water conveyed from the pump unit and an outflow portion that discharges the water in the water storage portion to the humidification filter. The humidifying filter is based on a knitted fabric having an outer material having an opening, a lining having an opening, and a thread having water absorbency connecting the outer material and the lining. A wale direction provided perpendicular to the direction in which water drips from the outflow portion and a course direction orthogonal to the wale direction are provided, and the wale direction is a portion where the threads are in contact with each other rather than the course direction. The water is more likely to permeate in the horizontal direction than in the vertical direction, which is the direction in which water drips from the outflow portion.

According to the present invention, a main body case having a suction port and an air outlet, a water storage container for storing water in the main body case, a humidifying filter for retaining water, and the humidifying filter provided above the humidifying filter. A supply unit that supplies water to the water supply unit, a pump unit that sends water in the water storage container to the supply unit, and an air blower that sucks air outside the main body case from the suction port and blows it out from the air outlet through the humidifying filter. The supply unit includes a water storage portion that stores water conveyed from the pump unit and an outflow portion that causes the water in the water storage portion to flow out to the humidification filter. A knitted fabric having an outer material having an opening, a lining having an opening, and a thread having water absorption connecting the outer material and the lining is used as a base material, and water drips from the outflow portion of the knitted fabric. It includes a wale direction provided perpendicular to the direction and a course direction orthogonal to the wale direction. In the wale direction, there are more portions where the threads are in contact with each other than in the course direction, and water is provided from the outflow portion. It is characterized by having the property that water easily permeates in the horizontal direction rather than the vertical direction, which is the direction in which water drops.

FIG. 3 is a perspective view showing details of the supply unit 15 according to the first embodiment of the present invention. FIG. 4 is a cross-sectional view showing a BB cross section of FIG.

As shown in FIGS. 3 and 4, the humidifying filter 12 is self-supporting by being sandwiched between the frame A31 and the frame B32 which are opened so that the air from the blower portion 3 can flow. A supply unit 15 is provided at the upper end of the frame B32.

The supply unit 15 temporarily stores water at the upper end of the humidifying filter 12, a water storage portion 33, an inflow portion 34 in which the water conveyed from the pump portion 14 flows into the water storage portion 33, and water in the water storage portion 33. The outflow portion 35 that flows out to the humidifying filter 12 is provided, and the outflow portion 35 is provided with a weir 36 that temporarily stores a certain amount of water. In the present embodiment, one inflow portion 34 is provided in the central portion at the upper part of the humidifying filter 12, and a plurality of outflow portions 35 are provided at equal intervals on the upper part of the humidifying filter 12. Further, the bottom surface of the water storage portion 33 is inclined downward toward the weir 36.

The outflow portion 35 is provided with an induction portion 37 that suppresses the action of surface tension of water and makes it easier for water to get over the weir 36. The guide portion 37 includes a first rib 38 projecting upward from the upper surface of the weir 36, a second rib 39 extending from the first rib 38 to the water storage side, and a second rib 39. , Extending downward, and part of it has entered the water inside the weir 36.

Are in contact or intruding.

When the water gets over the weir 36, the water surface rises due to the influence of the surface tension, and when the water exceeds the surface tension, the water goes over the weir 36 and is supplied to the humidifying filter 12. In this case, non-uniformity such as water flowing rapidly or water flowing only from a part of the outflow portions 35 occurs in a plurality of outflow portions 35. In order to suppress the above, the induction portion 37 intentionally intricates the shape of the end portion where surface tension occurs in the portion of the weir 36, and suppresses the action of surface tension to the minimum. Further, when the induction portion 37 is brought into contact with or enters the water of the water storage portion 33 or the humidifying filter 12, the humidifying filter 12 in contact with the water starts to flow and attracts the water due to the viscous action of the water, and the surface tension is increased. The effect of can be minimized.

The water conveyed by the pump unit 14 is sent from the inflow portion 34 to the water storage portion 33, and is temporarily stored by the weir 36. Then, the water that has passed through the weir 36 is supplied to the humidifying filter 12 by the water supply. The weirs 36 provided in the plurality of outflow portions 35 are arranged at the same height, and substantially the same amount of water is supplied to the humidifying filter 12 over the respective weirs 36. In this way, water is uniformly supplied to the humidifying filter 12.

Further, the outflow portion 35 is provided in the upstream portion of the humidifying filter 12 in the blowing direction, and water is supplied to the upstream side in the blowing direction at the upper portion of the humidifying filter 12. Water is supplied while flowing down in the humidifying filter 12 and spreading in the humidifying filter 12 due to its inundation action. It spreads further by the action of blowing air, and also has the effect of suppressing the formation of an excessively inundated portion of water at the rear end of the humidifying filter 12 in the blowing direction and suppressing water splashing caused by the wind.

FIG. 5 shows an example of mounting the humidifying filter 12 in the present embodiment, and FIG. 6 shows an enlarged fiber composition of the humidifying filter 12.

As shown in FIG. 6, the humidifying filter 12 is a humidifying filter 12 based on a double Russell knitted fabric having openings 53 in the outer material 51 and the lining 52.

The humidifying filter 12 is made of a water-absorbent thread 54, and the opening 53 has a hexagonal shape. The double Russell knitted fabric refers to a knitted fabric composed of an outer material 51 and a lining 52, and a thread 54 connecting the outer material 51 and the lining 52. In FIG. 5, A is the wale direction and B is the course direction. In the wale direction, there are more parts where the threads come into contact with each other than in the course direction, and the amount of water absorption due to the capillary phenomenon between the threads can be increased, and the threads do not meander and can absorb water linearly, so that the water absorption is more linear than in the course direction. Water is easy to penetrate.

The outer material 51, the lining 52, and the thread 54 connecting the outer material 51 and the lining 52 are water-absorbent fibers. For example, synthetic fibers include polyester, acrylic, nylon, vinylon, rayon, polynosic, cupra, acetate, triacetate, and promix. Examples of natural fibers include silk, wool, cotton, and linen. Further, the water absorption rate of the knitted fabric, the yarn or the fiber may be improved by supporting an inorganic compound such as silica gel or zeolite or a yarn piece such as a cotton linter on these fibers.

FIG. 6 is a view when the humidifying filter 12 of FIG. 5 is mounted in the humidifying device, and the humidifying filter 12 is in the direction in which water drips from the outflow portion 35 of the supply unit 15 (also referred to as a downward direction or a vertical direction). Is arranged so as to be the course direction B of the humidifying filter 12, and the direction perpendicular to the direction in which water drips from the outflow portion 35 (also referred to as the lateral direction or the horizontal direction) is the wailing direction A of the humidifying filter 12. ing.

As a result, the water dripping from the outflow portion 35 permeates in both lateral directions (wale direction) in which the water of the humidifying filter 12 easily permeates. In addition, since gravity is applied to the permeated water, it also permeates in the downward direction (course direction), and the water can be distributed throughout the humidifying filter 12 in a short time to retain water. That is, the humidifying filter 12 has a property that water easily permeates in the lateral direction rather than the upper limit direction when the humidifying filter 12 is mounted in the humidifying device.

The humidification operation in the above configuration will be described. When the pump 17 is driven by the pump motor 18, the pump 17 sucks up the water in the water storage container 11 and is arranged above the humidifying filter 12 via the first pipe 19, the connecting unit 21, and the second pipe 20. Water is sent to the supply unit 15. The supply unit 15 drops the water sent from the second pipe 20 onto the humidifying filter 12. The humidifying filter 12 retains a part of the dropped water. The excess water that is not retained by the humidifying filter 12 is returned to the water storage container 11 via the tray portion 16. In this state, when the blades 28 are rotated by the motor 27 of the blower unit 3, the air outside the main body case 1 is sucked into the first space portion 5 from the suction port 7 and blown to the humidifying filter 12. Air is humidified when passing through the water-retaining humidifying filter 12, and the humidified air is blown from the air outlet 8 to the outside of the main body case 1 through the air supply port 30 and the discharge port 29 of the air blowing unit 3. ..

The humidifying filter is not limited to the double Russell knitted fabric shown in the present embodiment, and the same effect can be obtained if the humidifying filter has water permeability in one direction.

The feature of this embodiment is that the direction in which water easily permeates the humidifying filter is arranged in the direction perpendicular to the direction in which water is dropped from the water supply unit 15 (outflow unit 35) (horizontal direction). ..

As a result, water can be distributed throughout the humidifying filter 12 in a short time to retain water, so that the operation can be performed with the maximum moisturizing amount performance in a short time.

The humidifying device according to the present invention is useful as a humidifying device or the like used for home use or office use.
