Description

Technical Field

[0001] The present invention relates to the field of air conditioning technology, in particular to an air processing device including a humidifier, and particularly to an improvement of the humidifier. Background Art

[0002] Air handling equipment such as air conditioners are increasingly used in people's lives to meet people's needs for living and working environments. Many air handling equipment have a humidification function to adjust the air humidity in the environment.

[0003] Among the common humidifiers currently, one type transports water to the top of the humidifier and pours water on the top of the humidifier. Under the action of gravity, the water penetrates downward along the moisture permeable membrane of the humidifier. When dry wind passes through the moisture permeable membrane, the moisture will be carried away by the wind, thereby humidifying the air.

[0004] Another type of humidifier has a filter element with capillary action, which is immersed in a water tank. Under the capillary action, water in the water tank is sucked onto the moisture permeable membrane of the filter element from bottom to top to humidify the dry air blowing through the filter element.

[0005] These existing humidifiers have some problems in the application process, such as the slow water absorption speed of the moisture permeable membrane and the limited amount of water it can absorb, which makes it difficult to improve the humidification capacity of the humidifier. Moreover, after long-term humidification use, the moisture permeable membrane is easy to deform, thus affecting the humidification function of the humidifier.

[0006] In response to the technical problems of these prior art humidifiers, a humidifier with a humidifying element has been developed. The humidifying element includes a plurality of hollow chips, which are used for passing water and air respectively, and can also be called water side chips and air side chips. The water side chips and the air side chips are alternately stacked on each other, and a moisture permeable membrane is sandwiched between adjacent water side chips and air side chips, thereby forming a humidifying element.

[0007] For this type of humidifier element, the design process will consider reducing the width of the water side, such as reducing the thickness of the water side chip. In this way, under the condition that the overall width of the core remains the same, the number of air layers and water layers can be increased, thereby increasing the humidification capacity. Moreover, by reducing the thickness of the water layer, the cross-sectional area for air to pass through the humidifier element will be relatively increased, thereby reducing ventilation resistance. However, it was found in use that if the water layer is too narrow, the surface tension of the water will make it difficult to drain the water. In this way, when it is necessary to drain the humidifier element or replace the water in it, there will be a problem of incomplete drainage. The water remaining in the humidifier element is prone to accumulation of scale, etc., which will block the water passage in the humidifier element, and thus affect the driving performance of the humidifier.

[0008] Therefore, how to prevent scale from accumulating in the humidifying element of the humidifier while improving the humidifying performance of the humidifier as much as possible is still a problem that needs to be further solved. Summary of the invention

[0009] The present invention is made to solve the problems existing in the prior art mentioned above. The purpose of the present invention is to provide an improved humidifier and an air treatment device including the humidifier, which can improve the humidification performance of the humidifier, such as improving the humidification efficiency, reducing the ventilation resistance, etc., while preventing the accumulation of scale.

[0010] The humidifier of the present invention includes a humidifying element, which has an air inlet, an air outlet, a water inlet and a humidifying core. The air inlet and the air outlet are connected to the opposite sides of the humidifying core for air to flow into and out of the humidifying core, and water can be injected into the humidifying core through the water inlet. The humidifying core includes: a plurality of first hollow chips, the first hollow chips are connected to the air inlet and the air outlet; a plurality of second hollow chips, the second hollow chips are connected to the water inlet, and the second hollow chips are arranged alternately with the first hollow chips; and a plurality of moisture permeable membranes, each of which is sandwiched between adjacent first hollow chips and second hollow chips. The first hollow chip has a first thickness, the second hollow chip has a second thickness, the first thickness is greater than the second thickness, and if the first thickness is t1 and the second thickness is t2, the following condition is satisfied: 0.4≤t2 / t1<1.

[0011] In the humidifier of the above structure, the first hollow chip is connected to the air inlet and the air outlet, and air flows into it, so it is an air-side chip, and the second hollow chip is connected to the water inlet, and water for humidification flows into it, so it is a water-side chip. Studies have shown that by setting the thickness of the first hollow chip, i.e., the air-side chip, to be greater than the thickness of the second hollow chip, i.e., the water-side chip, and specifically setting the ratio of the two thicknesses between 0.4 and 1, a better humidification efficiency can be achieved, and the resistance to air flowing through the humidifying element can also be smaller. At the same time, when draining water, no water residue will be generated due to water tension, thereby reducing the risk of scale formation in the humidifying element.

[0012] At least one of the first hollow core and the second hollow core is made of synthetic resin. Specifically, the synthetic resin may include one selected from the following materials: polypropylene and polycarbonate.

[0013] Preferably, the second hollow chip is treated with a hydrophilic process, for example, a hydrophilic coating may be applied to the second hollow chip, or the second hollow chip may be subjected to a corona treatment, etc. In the case where the first hollow chip and the second hollow chip are formed of synthetic resins such as polypropylene and polycarbonate, they exhibit hydrophobicity, which will hinder the discharge of water due to the surface tension of water, and by treating the second hollow chip with a hydrophilic process, water can be evenly distributed on the surface of the hollow chip and is not easy to gather together, which will facilitate the discharge of water.

[0014] Preferably, a moisture permeable film is attached to both sides of the second hollow chip, respectively. The moisture permeable film is bonded to both sides of the second hollow chip, which can facilitate the subsequent processing in the humidifying element.

[0015] Preferably, the moisture-permeable film can be bonded to both sides of the second hollow chip using an adhesive, and the adhesive can be selected from at least one of the following types: silicone adhesives, epoxy resin adhesives, polyurethane adhesives, acrylic adhesives, vinyl acetate adhesives, vinyl chloride adhesives, cyclic polyolefin resin adhesives and latex adhesives.

[0016] In addition, the moisture permeable film may be attached to the second hollow core by other methods, such as hot melting.

[0017] In a preferred structure, each first hollow chip includes a first frame and at least one first reinforcing rib extending between two opposite sides of the first frame, and each second hollow chip includes a second frame and at least one second reinforcing rib extending between two opposite sides of the second frame, and the first hollow chip and the second hollow chip are arranged so that the first reinforcing rib and the second reinforcing rib intersect each other. The first reinforcing rib and the second reinforcing rib are arranged in at least one of the following situations: the first reinforcing rib is inclined relative to the two opposite sides of the first hollow chip; and the second reinforcing rib is inclined relative to the two opposite sides of the second hollow chip.

[0018] The inclined arrangement of the first and second reinforcing ribs can facilitate uniform distribution of air and water flow in the hollow core, thereby improving humidification efficiency.

[0019] Preferably, the humidifying element includes a first part and a second part, the first part corresponds to a part of the air inlet with a high air flow rate, and the second part corresponds to a part of the air inlet with a low air flow rate, wherein the thickness of the first hollow chip in the first part is smaller than the thickness of the first hollow chip in the second part.

[0020] The invention also relates to an air treatment device, comprising the humidifier as described above.

[0021] Preferably, the air treatment device comprises a shell, on which an air inlet, an air outlet and an air supply path extending between the air inlet and the air outlet are arranged, wherein the humidifier is located in the air supply path or is connected to the air supply path.

[0022] Preferably, the area between the humidifying element and the air inlet includes a first area and a second area, the cross section of the first area in a direction perpendicular to the air flow path faces the air inlet, and the second area is adjacent to the first area, wherein the humidifying component includes a first part and a second part, and when the humidifying element is installed in the shell, the first part corresponds to the first area, and the second part corresponds to the second area, the first hollow chip in the first part has a first thickness, and the first hollow chip in the second part has a second thickness, and the first thickness is less than the second thickness.

[0023] The setting of different thicknesses of the first hollow core can make the air flow rate uniform throughout the entire humidifying element, and the uniform air flow rate helps to improve the humidification efficiency of the humidifying element. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] In order to facilitate the understanding of the present invention, the specific implementation of the humidifier in the air treatment equipment of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the drawings show only preferred embodiments of the present invention, which should not be construed as limiting the scope of the present invention. Those skilled in the art can make various obvious modifications, variations, and equivalent substitutions to the present invention based on the embodiments shown in the drawings, and the technical features of the different embodiments described below can be arbitrarily combined with each other without contradiction, and these all fall within the scope of the present invention.

[0069] In the following specific description of the present invention, terms such as "upper", "lower", "top", "bottom" and the like are used based on the use state of the humidifier shown in the figure.

[0070] Figure 1 The humidifying element 10 of the humidifier of the present invention is shown in a perspective view. The humidifying element 10 can be used in an air treatment device, for example.

[0071] The humidifying element 10 includes a fixing frame 11, which is respectively arranged at the top and bottom of the humidifying element 10, and a top plate 12 is arranged at the top of the humidifying element 10, and a bottom plate 13 is arranged at the bottom of the humidifying element 10. The fixing frame 11 fixes the humidifying element 20 composed of a plurality of stacked chips, and can prevent the plurality of chips constituting the humidifying element 20 from spreading. The top plate 12 and the bottom plate 13 further play the role of fixing the humidifying element 20 from the top and bottom, and seal the humidifying element 20 from the top and bottom. Preferably, side plates 14 are also arranged on both sides of the humidifying element 20, which help to improve the strength and sealing of the humidifying element 10.

[0072] In the structure shown in the figure, the fixing frame 11 is provided on both the top and the bottom of the humidifying element 10, however, the fixing frame 11 may be provided on one of the top and the bottom.

[0073] The humidifying element 10 also includes a water inlet and a water outlet. For example, in the exemplary structure shown in the figure, a first pipe portion 15 is provided on the top plate 12 of the humidifying element 10, and the first pipe portion 15 serves as a water outlet. In addition, a second pipe portion 16 is provided on the bottom plate 13 of the humidifying element 10, and the second pipe portion 16 can serve as a water inlet, so that water can be injected into the humidifying element 20 of the humidifying element 10 through the second pipe portion 16. In the process of injecting water from the second pipe portion 16 into the humidifying element 20, the air in the humidifying element 20 can be discharged through the first pipe portion 15, so that the humidifying element 20 can be filled with water. When humidification is stopped, the water in the humidifying element 20 can be discharged through the first pipe portion 15, thereby preventing the growth of bacteria caused by the long-term presence of water in the humidifying element 20. Such a water inlet-water outlet structure is simple, which helps to facilitate water inlet and water outlet, and the operation efficiency of water inlet and water outlet of the humidifying element is also high. Of course, a port can also be provided at the bottom of the humidifying element 10, which serves as both a water inlet and a water outlet. When humidification is required, water is added to the humidifying element 20 from the bottom upward through the port, while the port at the top (e.g., the first pipe portion 15) is only used to exhaust air to make room for water.

[0074] As shown in the figure, a second pipe portion 16 is provided at the bottom port of the humidifying element, and the second pipe portion 16 can be connected with a water pipe so as to replenish water to the humidifying element.

[0075] This water intake method helps to quickly drive away the air in the humidifying element 20, maintain the air pressure balance in the humidifying element 20, increase the contact area between the water and the moisture permeable membrane 50 (described in detail below), and thus improve the humidification capacity. In addition, the water intake and drainage through the same port can ensure that the internal pressure of the humidifying element 20 of the humidifying element 10 is balanced when replenishing water, prevent the moisture permeable membrane 50 from being deformed or even damaged by force, and help to extend the service life of the humidifying element 10. In addition, the wet membrane can be cleaned by drainage to prevent scaling.

[0076] The humidifying element 10 further includes an air inlet 21 and an air outlet 22 connected to the humidifying element 20. Air enters the humidifying element 20 from the air inlet 21 and then flows out from the air outlet 22. Figure 1 In the structure shown in FIG. 1 , the air inlet 21 is actually the surface of the humidifying element 10 extending between the two side plates 14, which surface is open and faces the air inlet 3 of the air treatment device 1 (see FIG. 1 ). Figure 5 ), forming an opening that includes the entire front face of the humidifying element 20 to allow air to flow into the humidifying element. Accordingly, the air outlet 22 is the face ( Figure 1The back side of the humidifying element 20 is also open, forming an opening that covers the entire back side of the humidifying element 20 to allow air to flow out. When the air flows through the humidifying element 20, it contacts the water in the humidifying element 20, thereby being humidified. Preferably, as Figure 1 As shown, the cross section of the humidifying element 10 is rectangular along the height direction of the humidifying element 10. Moreover, the water inlet and / or the water outlet are arranged at the position corresponding to the long side of the rectangle, while the air inlet 21 and the air outlet 22 are arranged at the position corresponding to the short side of the rectangle. Through such an arrangement, the water storage capacity in the humidifying element 10 can be increased, and then the volume of the humidifying element 10 can be made smaller when the humidification capacity is equal, thereby contributing to the miniaturization of the humidifying element 10.

[0077] The structure of the humidifying element 20 will be described in further detail below.

[0078] The humidifying element 20 includes a plurality of first hollow chips 30, a plurality of second hollow chips 40, and a plurality of moisture permeable films 50. The first hollow chips 30 and the second hollow chips 40 are arranged alternately, and a moisture permeable film 50 is provided between adjacent first hollow chips 30 and second hollow chips 40. The first hollow chips 30, the second hollow chips 40, and the moisture permeable films 50 are stacked to form the humidifying element 20, and the above-mentioned fixing frame 11, top plate 12, and / or bottom plate 13 hold the stacked first hollow chips 30, the second hollow chips 40, and the moisture permeable films 50 together to prevent them from spreading.

[0079] The first hollow chip 30 is connected to the air inlet 21 and the air outlet 22, and air can flow through the first hollow chip 30. Figure 1 As can be seen in FIG. 1 , the channel in the first hollow core 30 is connected to the air inlet 21, so that air can flow into the first hollow core 30 through the air inlet 21. Figure 1 On the back side of the first hollow chip 30, the channel of the first hollow chip 30 is also connected to the air outlet 22, so that air can flow out. The second hollow chip 40 is connected to the first tube part 15 (water outlet) and the second tube part 16 (water inlet), and water can be contained in the second hollow chip 40. Specifically, a space for containing water is formed in the chassis 13, the second tube part 16 is connected to the space in the chassis 13 to allow water to enter the space, and the channel in the second hollow chip 40 is connected to the space in the chassis 13 to allow water to flow into the second hollow chip 40. It can be seen that the first hollow chip 30 acts as an air side chip, and the second hollow chip 40 acts as a water side chip.

[0080] Preferably, the first hollow core 30 and the second hollow core 40 have a plurality of hollow channels therein. Thus, the structure of these hollow channels can make the first hollow core 30 and the second hollow core 30 have good waterproof and corrosion resistance and high strength. For example, the first hollow core 30 and the second hollow core 30 can be made of corrugated board.

[0081] At least one of the first hollow chip 30 and the second hollow chip 40 may be made of a synthetic resin material, for example, one of polypropylene (PP), polycarbonate and the like. For the second hollow chip 40, synthetic resin materials such as polypropylene (PP) and polycarbonate are hydrophobic, which makes it difficult for the water in the second hollow chip 40 to be discharged due to tension. To this end, the second hollow chip 40 may preferably be subjected to a hydrophilic process treatment, for example, a hydrophilic coating may be coated on the second hollow chip 40, or the second hollow chip 40 may be subjected to a corona treatment. Through the hydrophilic process treatment, water can be evenly distributed on the surface of the second hollow chip 40, promoting the flow of water, thereby facilitating the discharge of water.

[0082] Figure 2 A schematic plan view showing an exemplary structure of a first hollow chip 30 and a second hollow chip 40 stacked together is shown. Figure 3 A perspective view showing a first hollow chip 30 and a second hollow chip stacked together is shown. Figure 4 is Figure 3 The first hollow core 30 includes a first frame portion 31 and at least one, preferably a plurality of first reinforcing ribs 32 extending between two opposite sides (e.g., two vertical sides in the figure) of the first frame portion 31. Preferably, the first reinforcing ribs 32 extend at an angle relative to the first frame portion 31, for example, as shown in the figure, forming a first angle α relative to the two vertical sides of the first frame portion 31.

[0083] The second hollow core 40 includes a second frame portion 41 and at least one, preferably a plurality of second reinforcing ribs 42 extending between two opposite sides (e.g., two horizontal sides in the figure) of the second frame portion 41. Preferably, the second reinforcing ribs 42 extend at an angle relative to the second frame portion 41, for example, as shown in the figure, forming a second angle β relative to the two horizontal sides of the second frame portion 41.

[0084] The situation where the first reinforcing rib 32 and the second reinforcing rib 42 extend obliquely as shown in the figure is preferred. The first reinforcing rib 32 can also be arranged to form a right angle with the two vertical sides of the first frame portion 31, and the second reinforcing rib 42 can be arranged to form a right angle with the two horizontal sides of the second frame portion 41. This is also within the scope of the present application.

[0085] A moisture permeable film 50 is sandwiched between the first hollow core 30 and the second hollow core 40. Figure 4As shown, the first hollow chip 30 and the second hollow chip 40 support the moisture permeable film 50 therebetween, so that the moisture permeable film 50 is not easily deformed during use. Specifically, the moisture permeable film 50 can be sealed and connected with the adjacent first hollow chip 30 and the second hollow chip 40 by means of heat pressing, gluing, etc. During the humidification process, the water contained in the second hollow chip 40 can pass through the moisture permeable film 50 and be taken away by the dry air passing through the first hollow chip 30, that is, the air passing through is humidified.

[0086] When the first hollow core 30 and the second hollow core 40 are stacked together, the first reinforcing rib 32 of the first hollow core 30 and the second reinforcing rib 42 of the second hollow core 40 intersect with each other, thereby further improving the strength of the humidifying element 20 and helping to prevent deformation of the moisture permeable membrane 50. In addition, the intersection of the first reinforcing rib 32 and the second reinforcing rib 42 also separates a plurality of moisture permeable areas 23.

[0087] Preferably, a moisture permeable film 50 is attached to both sides of the second hollow core 40. For example, the moisture permeable film 50 can be bonded to the second hollow core 40 by an adhesive. The adhesive used to bond the second hollow core 40 and the moisture permeable film 50 together can be at least one selected from the following adhesive types: silicone adhesive, epoxy adhesive, polyurethane adhesive, acrylic adhesive, vinyl acetate adhesive, vinyl chloride adhesive, cyclic polyolefin resin adhesive and latex adhesive.

[0088] In addition to adhesives, other methods may be used to attach the moisture-permeable film 50 to the second hollow core 40, such as by hot melting.

[0089] Furthermore, the first hollow core 30 and the second hollow core 40 are arranged such that the flow direction of the air flowing through the first hollow core 30 is ( Figure 2 ) and the flow direction of the water flowing through the second hollow core 40 ( Figure 2 In this way, the water flow pressure and air pressure on the moisture permeable membrane 50 are in different directions, thereby alleviating the pressure on the moisture permeable membrane 50, which can help reduce deformation.

[0090] Preferably, the first angle α is an acute angle, that is, the first reinforcing rib 32 extends obliquely relative to the first frame portion 31. In this way, a first through hole 33 is formed on the first reinforcing rib 32, and the first through hole 33 leads to the corresponding moisture permeable area 23, which helps the air to flow into and be distributed in the moisture permeable area 23 evenly.

[0091] Similarly, the second angle β is preferably an acute angle, that is, the second reinforcing rib 42 extends obliquely relative to the second frame portion 41, thereby including a second through hole 43 on the second reinforcing rib 42, which leads to the corresponding moisture permeable area 23, which helps water to flow into and be distributed evenly into the moisture permeable area 23.

[0092] Back to Figure 2 It can be seen that in the first hollow core 30, the spacing between two adjacent first reinforcing ribs 32 is preferably equal, and the spacing is the first spacing L1. In the second hollow core 40, the spacing between two adjacent second reinforcing ribs 42 is preferably also equal, and the spacing is the second spacing L2. Preferably, the first spacing L1 is smaller than the second spacing L2. By setting the first spacing L1 between adjacent first reinforcing ribs 32 to be smaller than the second spacing L2 between adjacent second reinforcing ribs 42, the moisture permeable membrane 50 will not be deformed too much due to the water pressure, thereby causing the passage on the air side to become narrower, thereby making the airflow smoother.

[0093] The above-mentioned inclination angles of the first reinforcing ribs 32 and the second reinforcing ribs 42 and the arrangement of the first and second intervals L1 and L2 thereof help to maximize the area of ​​the moisture permeable region, and thus ensure the humidification efficiency of the humidification assembly.

[0094] As in Figure 4 As more clearly shown in FIG. 3 , the first hollow core 30 has a first thickness t1, and the second hollow core 40 has a second thickness t2. The second thickness t2 is less than the first thickness t1, for example, the second thickness t2 may be 1 to 2 mm, such as 1.8 mm, and the first thickness t1 may be 2 to 4 mm, such as 3 mm.

[0095] Further, the ratio between the second thickness t2 and the first thickness t1 is preferably selected in the following range: 0.4≤t2 / t1<1. For example, when the second thickness t2 is 1.8 mm and the first thickness t1 is 3 mm, t2 / t1 is 0.6.

[0096] In addition, the thickness of the first hollow chip 30 in the same humidifying element 10 can also be variable. It is found during use that the flow rate of the air entering the air inlet 21 will be different, with a large flow rate in some places and a small flow rate in some places. Specifically, the air flow rate of the air inflow in the part of the air inlet 21 that is roughly aligned with the air inlet 3 of the air treatment device 1 is relatively large, while the air flow rate in the surrounding part is relatively small. In view of this phenomenon, the humidifying element 10 can be configured to include a first part and a second part, wherein the first part corresponds to the part with a large flow rate of the air flowing into the air inlet 21, and the second part corresponds to the part with a small flow rate of the air flowing into the air inlet 21. In addition, the thickness of the first hollow chip 30 in the first part is set to be less than the thickness of the first hollow chip 30 in the second part. The smaller thickness of the first hollow chip 30 provides a narrower air channel, thereby providing a greater flow resistance to the air, which can decelerate the air with a faster flow rate. In this way, the air flow rate can be made uniform throughout the range of the humidifying element 10. A uniform air flow rate helps to improve the humidification efficiency of the humidifying element 10 .

[0097] Furthermore, in addition to the humidifying element 10, the humidifier may optionally include a water tank and a regulating valve. The water tank may be connected to a water inlet, such as the second pipe portion 16 shown in the figure, and the regulating valve is disposed between the water tank and the second pipe portion 16 for regulating the amount of water input into the humidifying element 20.

[0098] As an alternative or additional situation, the water tank can also be connected to the municipal waterway, or, can also be filled with water manually. These are all within the scope of the present invention.

[0099] The humidifier including the humidifying element 10 can be used in the air treatment device 1. Figure 5 As shown, the air treatment device 1 includes a housing 2, on which an air inlet 3 and an air outlet 4 are arranged, and an air supply path 5 is formed between the air inlet 3 and the air outlet 4. A water inlet assembly 6, a water tank 7 and a humidifying element 10 of the humidifier are arranged in sequence on the air supply path. Preferably, the water inlet assembly 6 and the water tank 7 are arranged close to the side wall of the housing, so that the obstruction of the various components of the humidifier to the airflow can be minimized, and such a layout is conducive to the miniaturization of the air treatment device 1.

[0100] The water inlet assembly 6 and the water tank 7 are in communication via a first water pipe 8 , and the water inlet assembly 6 can be connected to a water source such as municipal water, so that water can flow into the water tank 7 through the water inlet assembly 6 and the first water pipe 8 .

[0101] The water tank 7 and the humidifying element 10 are connected through the second water pipe 9, and the regulating valve described above is arranged on the second water pipe 9, and the regulating valve is, for example, a three-way valve. The three-way valve can be switched between a first position and a second position. Among them, in the first position, the water tank 7 and the humidifying element 10 are connected, and the water in the water tank 7 flows into the humidifying element 10 through the second water pipe 9 and the second pipe part 16 of the humidifying element 10. In the second position, the humidifying element 10 is in a drainage state, and the water in the humidifying element 10 flows to the three-way valve through the second pipe part 16 and is discharged from the water outlet end of the three-way valve.

[0102] In another alternative embodiment, the humidifier may be disposed outside the housing 2 and connected to the air supply path 5 in the housing 2 .

[0103] In this way, the humidifier can use the air supply components and air supply paths of the air treatment device to transport humidified air into the room; moreover, the humidifier can humidify the air after the air treatment device processes the air delivered into the room (such as introducing fresh air, adjusting the air temperature, and purifying the air), which can better ensure the comfort and cleanliness of the humidified air.
