Description

Wet curtain assembly and humidifier

Technical Field

The invention relates to the technical field of household appliances, in particular to a wet curtain component and a humidifier.

Background

The core component of the evaporative humidifier is a wet curtain, also called an evaporative filter element, and the working principle of the evaporative humidifier is that the air blows the wet curtain to evaporate moisture on the wet curtain, and the air with water mist volatilizes to the outside to improve the ambient humidity, so that the reasonable arrangement of the wet curtain structure can influence the effect of the evaporation process.

Most of evaporative humidifier structures on the market at present are in a mode that a water pump pumps water to pour a wet curtain from top to bottom, and drain holes are formed in the upper end of the wet curtain and used for draining water to the wet curtain through the drain holes so as to distribute liquid. On this basis, when the discharge flow is great, moisture accumulation easily appears in wet curtain inside, forms the cascade, especially to the structure that wet curtain is nearer to the air outlet, under the circumstances that the amount of wind is big, the wet curtain is close to the air-out side and easily produces the flying water.

Disclosure of Invention

Accordingly, it is necessary to provide a wet curtain assembly and a humidifier which prevent water from being deposited and flying when moisture is likely to accumulate in the wet curtain, particularly in a structure where the wet curtain is relatively close to the air outlet and when the air volume is large, the wet curtain is likely to fly when the wet curtain is close to the air outlet.

A wet curtain assembly comprising:

a wet curtain body;

Above-mentioned wet curtain subassembly, from the wet curtain body of water-feeding end piece cloth watering in order to wet, moisture is along first direction transmission to fully wet curtain body along way, partial moisture still can reach the end piece that falls that is located the other end. Because the water feeding end piece and the water discharging end piece are made of water absorbing materials, moisture can be absorbed by the water feeding end piece and infiltrate the water feeding end piece when reaching the water feeding end piece, and then the water feeding end piece is used for transmitting the moisture to the wet curtain body to distribute liquid, the moisture of the distributed liquid can be more stably and uniformly transmitted to the whole wet curtain body under the buffering of the water feeding end piece, and the phenomenon that water flows excessively or excessively accumulates for a short time due to concentrated and unstable water flow is avoided. On the other hand, after wetting the wet curtain body, the excessive moisture can be absorbed by the whole sewer end piece and gradually discharged, so that the moisture accumulation is avoided. Thus, the moisture build-up problem within the wet curtain assembly can be ameliorated to avoid the problem of water fly.

In one embodiment, the wet curtain further comprises two support end pieces which are respectively arranged at two opposite sides of the wet curtain body in a second direction, the second direction intersects with the first direction, and the water absorption rate of the two support end pieces is smaller than that of the upper water end piece and the lower water end piece.

In one embodiment, the wet curtain further comprises ribs extending from one side of the wet curtain body to the opposite side along a third direction, and forming a water passing channel allowing water to pass through, wherein the third direction is intersected with the first direction and the second direction at the same time.

In one embodiment, the ribs extend from one side of the wet curtain body to the opposite side along a third direction, and the water passing channel is formed intermittently in the third direction.

In one embodiment, the wet curtain body is provided with a plurality of the ribs in the first direction.

Referring to fig. 1 to 3, an embodiment of the present invention provides a wet curtain assembly 100, which includes a wet curtain body 10, an upper water end piece 31 and a lower water end piece 33. The water supply end piece 31 and the water discharge end piece 33 are respectively provided at opposite sides of the wet curtain body 10 in the first direction (X direction shown in fig. 3), and the water supply end piece 31 and the water discharge end piece 33 are made of a water absorbing material.

The base material of the wet curtain body 10 is cloth with good water absorption, such as non-woven fabrics, and the wet curtain body 10 can be manufactured by folding the base material, so that the surface area of the wet curtain body 10 is increased on the premise of limited occupied space. The wet curtain body 10 obtained by folding can be regarded as being formed by a plurality of laminations 11, the laminations 11 are connected end to end in sequence, folds are formed between the adjacent laminations 11, the extending direction of the folds is the first direction, and the outer contour of the wet curtain body 10 is cuboid.

The first direction is the height direction of the wet curtain body 10 when in use, corresponds to the up-down direction in fig. 2, and is also the gravity direction, so as to fully use gravity to distribute liquid from top to bottom. When the wet curtain body 10 is used, the higher end in the first direction receives moisture and diffuses and transmits the moisture to the whole wet curtain body 10 along the wet curtain body 10, so that the evaporation efficiency of the moisture is fully improved, and the humidifying effect is enhanced. The moisture may be transported along the capillary or other pore structures inside the substrate of the wet curtain body 10, or may flow and be transported along the surface of the substrate under the action of gravity. The moisture can be absorbed by and transmitted through the water absorbing material with excellent water absorbing capacity, the water feeding end piece 31 made of the water absorbing material is arranged on the upper side of the wet curtain body 10 and is in contact with the wet curtain body 10, the water feeding end piece 31 is used for distributing liquid, the moisture can be transmitted to the wet curtain body 10 through the water feeding end piece 31, then is transmitted along the wet curtain body 10 and continuously wets the wet curtain body 10 flowing through along the way, and after the moisture fully wets the body, part of the moisture reaching the water discharging end piece 33 is absorbed and discharged by the water discharging end piece 33.

The wet curtain assembly 100 described above spreads moisture from the water supply end piece 31 to wet the wet curtain body 10, the moisture being transported in a first direction and sufficiently wetting the wet curtain body 10 along the way, a portion of the moisture also reaches the water discharge end piece 33 on the opposite side. Because the water supply end piece 31 and the water drain end piece 33 are made of water absorbing materials, when reaching the water supply end piece 31, moisture is firstly absorbed by the water supply end piece 31 coated on the wet curtain body 10 and infiltrates the water supply end piece 31, and then the water supply end piece 31 transmits the moisture to the wet curtain body 10 for distributing the moisture, and the moisture of the distributed moisture can be more stably and uniformly transmitted to the whole wet curtain body 10 under the buffering of the water supply end piece 31, so that the water flow is prevented from being concentrated and unstable, and the excessive water flow or short-time accumulated water is avoided. On the other hand, after wetting the wet curtain body 10, the excessive moisture is absorbed by the entire drain terminal 33 and gradually discharged to prevent the moisture from accumulating, thereby preventing the flying water.

Further, the wet curtain assembly 100 further includes two support end pieces 50 disposed on opposite sides of the wet curtain body 10 in a second direction (Y direction shown in fig. 3), wherein the second direction intersects the first direction, and the water absorption rate of the two support end pieces 50 is smaller than the water absorption rate of the water supply end piece 31 and the water discharge end piece 33.

Wherein, the water absorption is defined as W, G is the weight of the sample after drying, B is the weight of the sample after saturation with water in the unit of grams, and W= (B-G)/G×100% in the unit of grams. The support end pieces 50 are located at both sides of the wet curtain body 10 in the width direction in use, and the third direction corresponds to the left-right direction in fig. 2, and the support end pieces 50 play a role of fixedly supporting the wet curtain body 10. Wherein the two support end pieces 50 are made of a material having a lower water absorbing property than the water absorbing materials of the upper and lower

water end pieces

31 and 33.

Considering that the wet curtain assembly 100 is easily mildewed and smelly when not in operation, the wet curtain assembly 100 needs to be dried, and it is more difficult to complete thorough drying because the wind force blown through both sides in the width direction is weak during the drying process. Therefore, the support end member 50 is made of a material having a lower water absorption capacity, so that the water absorption capacity is reduced, and the time required for drying is naturally shortened and the difficulty of drying is reduced.

Further, both the upper water end piece 31 and the lower water end piece 33 are made of absorbent cotton, and the water absorption rate is not less than 200%. Both support end pieces 50 are made of a material having a cotton content lower than that of absorbent cotton, and the water absorption rate thereof is less than or equal to 100%.

Specifically, the water absorption rates of the upper water end member 31 and the lower water end member 33 may be selected to be 200%, 225%, 250%, 275%, 300%, etc., and the water absorption rates of the support end member 50 may be selected to be 100%, 80%, 65%, 50%, 30%, 15%, etc., without being limited thereto. The upper and

lower end pieces

31, 33 and the support end piece 50 are made of cotton-containing materials, such as needle punched cotton, and their water absorbing effect can be adjusted by adjusting the content of cotton therein, and it is understood that the cotton content in the water absorbing cotton used to make the upper and

lower end pieces

31, 33 is higher and the cotton content in the support end piece 50 is lower.

By virtue of the high water absorption, the water-feeding end piece 31 can absorb sufficient water and distribute the water downwards, and the water-discharging end piece 33 can fully absorb redundant water to avoid water accumulation in the wet curtain body 10. In addition, it can be seen that the water absorption rate of the support end piece 50 is significantly low, so that the difficulty of drying is reduced with the reduction of moisture even though the surface air quantity is small, and the problem of incomplete drying of both sides of the wet curtain assembly 100 can be effectively avoided.

In some embodiments, the wet curtain assembly 100 further includes ribs 70, the ribs 70 extending from one side of the wet curtain body 10 to an opposite side thereof in a third direction (Z direction as shown in fig. 3) and forming a water passage G allowing moisture to pass therethrough, the third direction intersecting both the first and second directions.

The third direction is the thickness direction of the wet curtain body 10 when in use, and corresponds to the direction perpendicular to the paper surface in fig. 2. The rib 70 plays a role of fixing and bonding, and is formed by applying glue to the surface of the base material constituting the wet curtain body 10, and one rib 70 is formed on one side surface of the base material. It will be appreciated that the ribs 70 extend in the second, width direction, over the entire wet curtain body 10, from one side of the support end piece 50 to the other side of the support end piece 50. The complete ribs 70 undoubtedly prevent the flow and transmission of moisture on the surface of the substrate, and greatly limit the liquid distribution capacity of the surface of the substrate. Therefore, the ribs 70 are formed with water passing channels G, which can allow moisture to pass through the ribs 70 along the first direction, reduce the blocking effect of the ribs 70 on the moisture transmission, avoid moisture accumulation, especially at the ribs 70, dredge the moisture on the surface of the substrate of the wet curtain body 10, and avoid water flying.

Further, the ribs 70 extend from one side of the wet curtain body 10 to the opposite side in the third direction, and intermittently form the water passing passage G in the third direction.

The ribs 70 extend from one side of the wet curtain body 10 to the other side in the third direction, that is, the thickness direction sufficiently supports the entire wet curtain body 10. At the same time, however, the bead 70 is also interrupted at a point where moisture can smoothly flow along the surface of the substrate through the bead 70 due to the absence of the obstruction of the bead 70, i.e., the water passage G. The intermittent ribs 70 may be obtained by intermittent gluing. The intermittent ribs 70 can facilitate drainage of water while sufficiently manufacturing the wet curtain body 10, thereby avoiding water accumulation. In addition, the intermittent ribs 70 can save material.

It should be appreciated that in other embodiments, the water passing channel G may be a hole formed on the rib 70, or the rib 70 may not extend completely to the other side of the wet curtain body 10, and the water passing channel G may be formed at a distance from the substrate surface of the other side, so long as the water passing channel G can allow water to pass through the rib 70 for downward liquid distribution, which is not limited herein.

Further, the wet curtain body 10 is provided with a plurality of ribs 70 in the first direction. The spacing between two ribs 70 adjacent in the first direction is 23mm-28mm. Preferably, ribs 70 are provided on both side surfaces of the base material, and all ribs 70 are uniformly spaced.

In general knowledge, the ribs 70 are formed on the surface of the substrate constituting the wet curtain body 10, and thus an increase in the number of ribs 70 increases the obstruction of moisture flowing on the surface of the substrate, thereby affecting the humidifying effect of the final wet curtain assembly 100. However, contrary to the prior art, the inventor's study and experiment found that, on the basis of the rib 70 having the water passage G, the proper increase of the number of ribs 70 can enhance the water drainage capability of the wet curtain assembly 100. For this reason, increasing the ribs 70 and increasing the density of the ribs 70 can enhance the structural stability of the wet curtain body 10, and at the same time, the uniform structure is adopted, so that the folding distance uniformity can be improved, and the humidifying efficiency of the wet curtain is higher under the same air quantity.

In this embodiment, considering that the minimum glue pitch of the glue dispensing apparatus commonly used in practice is approximately 25.4mm, the glue dispensing is performed with a single pitch, rather than multiple pitches, in other words, the interval between two adjacent ribs 70 in the first direction is 25.4mm. The ribs 70 of the single pitch have a more suitable density than the ribs 70 of the double or multiple pitches, and the ribs 70 of the single pitch sufficiently improve the support of the wet curtain body 10 on the premise of having the water passage G without excessively affecting the water transmission. Taking a wet curtain assembly 100 with a height of 100mm as an example, four ribs 70 can be arranged on one side of the wet curtain body 10, and eight ribs 70 are arranged on the front side and the back side. It will be appreciated that in other embodiments, the spacing between two ribs 70 adjacent in the first direction may also be 24mm, 26mm, 27mm, etc., without limitation.

In some embodiments, the upper water end piece 31 is provided with an upper water port (not shown) and/or the lower water end piece 33 is provided with a lower water port (not shown).

The water inlet is arranged to facilitate water to quickly pass through the wet curtain, the position of the water inlet can be selected according to actual needs and the water diversion situation in the wet curtain body 10, and the aim of adjusting the water discharging capacity and the water distribution is achieved. The water drain port is convenient for timely guiding out the redundant water of the wet curtain body 10 so as to avoid water accumulation in the wet curtain body when the water quantity is large.

In other embodiments, the water permeability may be enhanced by forming the holes in the upper water end piece 31 and/or the lower water end piece 33, and the like, which is not particularly limited herein.

In some embodiments, the wet curtain body 10 is treated with an antifoaming agent. The wet curtain assembly 100 is prone to blister during use, particularly when the water quality is cloudy, due to the presence of some active agent component remaining on the surface of the substrate of the wet curtain body 10 during use, particularly the first time. Therefore, the wet curtain body 10 is treated by the defoaming agent aiming at the phenomenon, the defoaming agent can reduce the surface tension of water, solution, suspension and the like, prevent foam from forming, or reduce or eliminate the original foam, and the problem of bubbles generated by the wet curtain body 10 can be solved by selecting the nontoxic and harmless defoaming agent.

In the wet curtain assembly 100, the wet curtain body 10 is provided with an upper water end piece 31 and a lower water end piece 33 made of a material having a water absorption rate of 200% or more on the upper and lower sides in the height direction, and two support end pieces 50 made of a material having a water absorption rate of 100% or less on the left and right sides in the width direction, respectively. In addition, a plurality of ribs 70 are uniformly arranged on two sides of the wet curtain body 10 at intervals in the height direction, and all ribs 70 are formed intermittently at certain positions to form water passing channels G which allow water to be transmitted along the surface of the substrate. When the wet curtain body 10 is subjected to liquid distribution, moisture fully infiltrates the water supply end piece 31 covered on the wet curtain body 10, is uniformly transferred to the wet curtain body 10 by the water supply end piece 31, and fully infiltrates the wet curtain body 10 gradually from top to bottom, and passes through the ribs 70 through the water passing channel G at the positions where the ribs 70 on the surface of the substrate are arranged. Finally, the excess moisture is absorbed and discharged by the drain terminal 33. Because the upper water end piece 31 and the lower water end piece 33 are made of absorbent cotton with excellent water absorption performance, moisture can be fully absorbed by the upper water end piece and transmitted through the upper water end piece, and the water channel G can also drain the moisture, water accumulation is not easy to occur in the wet curtain body 10, and the problem of water flying under the condition of large air quantity can be avoided. When the wet curtain assembly 100 is not required, it is first dried, and then the carrier end piece 50 is made of a material having a lower water absorption rate and contains relatively less moisture. Therefore, even in the case where the both-side air quantity is lower, the problem that the both sides of the wet curtain assembly 100 are difficult to thoroughly dry can be avoided. In addition, the wet curtain body 10 is treated with the defoaming agent, so that bubbles generated during use, particularly during initial use, can be avoided.

Referring to fig. 4, the present invention also provides a humidifier, including the wet curtain assembly 100 described above. It will be appreciated that, to achieve its normal function, the humidifier further includes an air duct assembly 200, a water pump, etc., which are not described herein. The wet curtain assembly 100 is disposed at an air outlet of the air duct assembly 200.

The air generated by the air duct assembly passes through the wet curtain assembly 100 at the outlet thereof and carries the moisture evaporated from the wet curtain assembly 100, so that the air flow blown out through the wet curtain assembly 100 is more moist, which is helpful for improving the humidity of the environment and creating a comfortable environment. By adopting the wet curtain assembly 100, water can be uniformly distributed on the wet curtain body 10, so that the wet curtain assembly has a better evaporation effect, and the efficiency of humidifying air is improved.

Specifically, the air duct assembly 200 adopts a centrifugal air duct structure, and although the air duct assembly 200 of the centrifugal air duct mechanism is positioned at the air outlet, the air on both sides of the central air is small, the wet curtain assembly 100 has the upper water end piece 31 and the lower water end piece 33 with excellent water absorption performance and the ribs 70 with the water passing channel G, so that the water accumulation can be avoided, and the water flying phenomenon under the condition of large air quantity is avoided. On the other hand, the water absorbing capacity of the carrier end part 50 is relatively weak and the amount of water absorbed is small. Therefore, even in the case that the air quantity at both sides of the air outlet is small, the difficulty of drying both sides of the wet curtain assembly 100 is not great, so that thorough drying is facilitated.

In addition, the humidifier should have all the advantages of the wet curtain assembly 100 described above, and will not be described herein.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
