Description

Humidifier and air treatment equipment

Technical Field

The utility model relates to the field of air conditioning technology, in particular to air treatment equipment comprising a humidifier, and in particular relates to improvement of the humidifier.

Background

Air treatment devices such as air conditioners, fresh air blowers, etc. are increasingly used in the life of people to meet the demands of people for living and working environments, and in order to further enhance the use experience of users, many air treatment devices incorporate a humidifying function for adjusting the air humidity of the treated air.

In an air treatment apparatus for an air conditioner or the like, there is a type of humidifier including a humidifying element composed of a chip and a moisture permeable film. The air is humidified with the moisture permeable membrane as it passes through the moisture permeable membrane, thereby increasing the humidity of the gas in the gas flow path.

Since the wet film is in contact with water for a long period of time and is even impacted by water flow, after a long period of use, it often occurs that the moisture permeable film breaks due to the influence of water pressure, in which case the water flow flows out of the humidifying element and may even leak to the outside of the air treatment apparatus, which has a serious negative effect on the reliability of the product.

For this reason, there is still a need to increase the strength of the core of the existing humidifying element, to enhance the reliability of use of the moisture-permeable membrane, and to avoid breakage thereof due to the pressure of the liquid and gas in use.

Detailed Description

The present utility model will be further described with reference to specific embodiments and drawings, in which more details are set forth in the following description in order to provide a thorough understanding of the present utility model, but it will be apparent that the present utility model can be embodied in many other forms than described herein, and that those skilled in the art may make similar generalizations and deductions depending on the actual application without departing from the spirit of the present utility model, and therefore should not be construed to limit the scope of the present utility model in terms of the content of this specific embodiment.

In the following detailed description of the present utility model, terms such as "upper", "lower", "top", "bottom", "vertical", "lateral", and the like are used with reference to the use state of the humidifier shown in the drawings.

As shown in fig. 1, the humidifier 10 mainly includes a humidifying element 20, a seal frame 30, a water tray 40, and a side seal plate 60. The humidifying element 20 has an air flow path and a water flow path intersecting each other, i.e. the air flow path and the water flow path pass through the main body portion of the humidifying element 20 in intersecting travelling directions.

In a preferred embodiment, as shown in fig. 2, the humidifying element 20 is formed in a substantially rectangular parallelepiped shape. In the state of being in contact, the opposite side surfaces (left side surface and right side surface of fig. 2) of the humidifying element 20 in the height direction are respectively arranged as the air flow inlet and air flow outlet of the air passage opening, which communicate with the air flow path inside the humidifying element 20. At least one other side (e.g., bottom side) of humidifying element 20 is in fluid communication with a water flow path in humidifying element 20. In a preferred embodiment, the waterway ports of humidifying element 20 include a water inlet and a water outlet, which may be disposed on the bottom side and the top side of humidifying element 20.

In this embodiment, a joint 41 is provided to the water tray 40 at the bottom of the humidifying element 20, and a water pipe is connected to the joint 41 to fill and drain water into and from the humidifying element 20. The water tray 40 on the top of the humidifying element 20 is provided with an air outlet, and when water is injected into the humidifying element 20, the original air in the humidifying element can be discharged from the air outlet, so that the pressure balance in the humidifying element is ensured, and the moisture permeable membrane is prevented from being deformed due to pressure change.

The water inlet may be provided in the water tray 40 at the bottom of the humidifying element 20, and the water outlet may be provided in the water tray 40 at the top.

Fig. 2 shows a perspective view of a humidifying element 20 according to a preferred embodiment of the present utility model. As shown in fig. 3, the humidifying element 20 includes, for example, a first chip 21 and a second chip 22. The first chip 21 and the second chip 22 each have a hollow structure. In some embodiments, the first chip 21 and the second chip 22 are cut from a hollow plate having a hollow structure. In other embodiments, chips 21 and 22 are integrally formed by injection molding. The first chip 21 and the second chip 22 thus molded each have a hollow structure and are formed in a sheet shape as a whole. Each of the first chip 21 and the second chip 22 has opposite surfaces, and the surface shape is substantially rectangular, the long side edge of the first chip 21 is provided with an air port, i.e., an air flow inlet and an air flow outlet, and the short side edge of the second chip 22 is provided with a water port, i.e., a water flow inlet and a water flow outlet. Along the outer contour of the rectangular plane, the first chip 21 and the second chip 22 are formed with respective first frame portions 216 and second frame portions 226. A plurality of reinforcing ribs 225 extending upward and downward are provided in the second frame portion 226 of the second core 22, the second reinforcing ribs 225 extending between upper and lower lateral portions of the second frame portion 226, the reinforcing ribs 225 being disposed parallel to each other but inclined with respect to the vertical direction or the vertical portion of the second frame portion 226 having the hollow vertical passage structure therein. A plurality of first reinforcing ribs 215 extending from left to right are provided in the first frame portion 216 of the first chip 21, the reinforcing ribs 215 extending between the vertical portions of the first frame portion 216, and similarly, the first reinforcing ribs 215 are disposed parallel to each other but are disposed obliquely with respect to the horizontal direction or the lateral portion of the first frame portion 216 in which the horizontal hollow passage is provided.

The inclined arrangement of the reinforcing ribs 215 and 225 can improve the overall strength of the chip, and the reinforcing ribs 215 and 225 can be horizontally arranged or vertically arranged.

Fig. 3 shows a partial schematic view of one subunit of the humidifying element 20 formed by stacking a plurality of first chips 21, a plurality of second chips 22, and a moisture-permeable film 23. As shown in fig. 5, the first chips 21, the second chips 22, and the moisture permeable film 23 are alternately arranged with their surfaces facing each other. Specifically, a sheet of moisture-permeable film 23 is provided between the surface of the adjacent first chip 21 and the surface of the second chip 22. One side surface of the moisture permeable film 23 may be connected to the frame portion of the adjacent second chip 22 and the surface of the reinforcing rib 221 by means of heat pressing, gluing, or the like, and the surface of the moisture permeable film 23 is pressed against the opposite side surface of the frame portion of the adjacent first chip 21 and the reinforcing rib 215 within the humidifying member 20. In this way, the frame portions and the ribs 215 and 225 on the outer circumferences of the first chip 21 and the second chip 22 support the moisture-permeable film 23 therebetween, and the moisture-permeable film 23 is easily deformed during use.

Fig. 4 shows a schematic plan view of the overlapping of the first chip 21 and the second chip 22, in which the moisture-permeable film 23 is omitted. It can be seen that the ribs 215 and 225 of the first and second chips 21 and 22 are offset from each other by a plurality of moisture permeable regions 235, and that the moisture permeable regions surrounding the frame portions of the chips 21 and 22 are surrounded by the respective ribs and the frame portions. It should be understood that since the first chip 21 and the second chip 22 are hollow structures, the hollow structures thereof are generally straight passages, the passages of the first chip 21 extend horizontally, and the passages of the second chip 22 extend vertically, so that when their reinforcing ribs 215 and 225 are arranged obliquely, the hollow structures thereof will be sufficiently opened into the moisture permeable region 235, and the hollow structures of the reinforcing ribs 215 and 225 allow the upper, lower, left and right adjacent moisture permeable regions 235 to communicate with each other. These moisture permeable regions 235 provide a region area for moisture transfer from the water containing spaces of the second chip 22 to the air containing spaces of the first chip. It should be appreciated that the larger the area of the moisture permeable region 235, the higher the humidification efficiency.

According to the preferred embodiment of the present utility model, referring to the use state of the humidifier 10, as shown in fig. 5, in the height direction of the use state of the humidifying element, the interval h1 between the adjacent first ribs 215 of the first chip 21 near the bottom thereof is smaller than the interval h2 between the adjacent first ribs 215 of the first chip 21 near the top thereof, i.e., h1< h2. Preferably, the spacing between adjacent first ribs 215 of the first chip 21 is smallest between two ribs 215 closest to the bottom, gradually increasing from the bottom toward the top.

On the other hand, the pitches of the second reinforcing ribs 225 of the second chip 22 are not always equal, and preferably, as shown in fig. 4, the pitch d2 between the second reinforcing ribs 225 adjacent in the middle of the second chip 22 is smaller than the pitch d1 between the second reinforcing ribs 225 adjacent near the side of the second chip, that is, d2< d1.

Since the reinforcing ribs 215 and 225 of the first and second chips 21 and 22 are not arranged at equal intervals, but are arranged such that the area of the moisture permeable region 235 at the bottom near the positions where the chips 21 and 22 are used is relatively small, particularly the area of the moisture permeable region 235 near the bottom side of the humidifying element 20 is relatively small, that is, the area of the moisture permeable region 235 at the position where the fluid pressure is relatively large is relatively small, it is possible to provide more sufficient support to the moisture permeable film 23, ensure the reliability of the moisture permeable film 23, and reduce the possibility of damage thereof. Meanwhile, the area of the moisture permeable region 235 near the top of the chips 21 and 22 is relatively large, particularly the area of the moisture permeable region 235 near both sides of the top edge of the chip is relatively large, and in the region where the fluid pressure is relatively small, the area of the moisture permeable region 235 is relatively large, thereby providing a larger moisture permeable area, which is advantageous for improving the humidifying efficiency of the humidifying element 20.

As shown more clearly in fig. 5, the first chip 21 has a first thickness t1 and the second chip 22 has a second thickness t2. Preferably, the first thickness t1 is greater than the second thickness t2, for example, the first thickness t1 may be 2 to 4mm, such as 3mm, and the second thickness t2 may be 1 to 2mm, such as 1.8mm.

The humidifier 10 described above may be integrated in the air treatment device 1. The air treatment device 1 comprises a housing, on which an air inlet 2 and an air outlet 3 are arranged, an air supply path extending between the air inlet 2 and the air outlet 3, and a humidifier 10 being arranged in the air supply path. Specifically, as shown in fig. 6, the air supply path of the air treatment apparatus is provided with a water inlet assembly 6, a water tank 5, and a humidifier 10, which are connected to each other by water pipes. Preferably, a heat exchanger 7 may also be included in the air treatment device 1. The water tank 5 and the water inlet assembly 6 in the air treatment device are arranged close to the side wall of the housing, so that the influence on the air flow obstruction is minimized, and the miniaturization of the air treatment device is facilitated.

In alternative embodiments, the humidifier 10 may be positioned adjacent to the air outlet, with the humidifier being positioned in connection with the air outlet.

The humidifier 10 is particularly useful for air treatment devices. The air treatment apparatus includes a housing on which an air inlet and an air outlet are provided, an air supply path extending between the air inlet and the air outlet, and a humidifier 10 disposed in the air supply path. Alternatively, the humidifier 10 is connected to the air outlet.

Since the non-equidistantly arranged reinforcing ribs are adopted in the humidifying element 20 of the humidifier 10 in the air treatment apparatus, the strength of the moisture permeable film in the humidifier is increased, and the humidifying efficiency of the humidifier 10 is maximized.

While the utility model has been described in terms of preferred embodiments, it is not intended to be limiting, but rather to the utility model, as will occur to those skilled in the art, without departing from the spirit and scope of the utility model. Therefore, any modification, equivalent variation and modification of the above embodiments according to the technical substance of the present utility model fall within the protection scope defined by the claims of the present utility model.
