Description

Technical Field

[0001] The utility model relates to the wet film humidification technology, and more specifically, to an air treatment device and a wet film humidifier thereof. Background Art

[0002] The wet film humidifier is a humidification device built in an air conditioner for humidifying air. The wet film humidifier usually adds water to the wet film by means of siphon water addition or water pump spraying water addition.

[0003] The siphon water addition method is to immerse one end of the wet film in water all the time and convey the water to the wet film through the siphon action. The siphon water addition method has a slow water addition speed, and since the wet film is immersed in water all the time, the wet film is always in a wet state, which is easy to breed bacteria, thus shortening the service life of the wet film.

[0004] The water pump spraying water addition method is to use a water pump and a supporting water pipe to spray water onto the wet film. Since a water pump and a water pipe need to be installed, the production cost is relatively high and the reliability is low. At the same time, when the water pump sprays water, small water droplets are easily driven by the air flow and blown out from the outlet of the wet film humidifier in the form of liquid droplets. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is how to improve the water addition speed of the wet film.

[0006] An embodiment of the utility model provides a wet film humidifier, which includes:

[0007] A housing, internally provided with an air duct and a water tank located at the bottom of the air duct;

[0008] A fan, connected to the housing, for driving air to flow along the air duct;

[0009] A humidification component, arranged in the air duct and above the water tank, including a mounting frame capable of rotating relative to the housing and a wet film arranged on the mounting frame; and,

[0010] A driving component, for driving the mounting frame to rotate;

[0011] Wherein, the driving component is configured to drive the mounting frame to rotate so that at least a part of the edge of the wet film enters the water tank.

[0012] In a schematic embodiment, a first notch is arranged at the edge of the wet film;

[0013] When the first notch rotates to face the water tank, the wet film is outside the water tank.

[0014] In a schematic embodiment, the wet film is configured as a circular diaphragm provided with the first notch, and the edge of the wet film at the first notch is a straight line.

[0015] In a schematic embodiment, the drive assembly further includes an external gear ring;

[0016] The mounting bracket is disposed within the external gear ring and connected to the external gear ring;

[0017] The drive assembly includes a drive motor disposed on the housing or the fan, and a driving gear sleeved on the drive motor and meshing with the external gear ring.

[0018] In a schematic embodiment, the humidifying assembly further includes:

[0019] A support frame, including a frame disposed in the air duct and above the water tank, a first support disposed at one end of the frame, and a second support disposed at the other end of the frame; and,

[0020] A rotating shaft, with two ends respectively connected to the first support and the second support;

[0021] Wherein, both the mounting bracket and the external gear ring are located between the first support and the second support and can rotate around the rotating shaft, an opening is provided on the bottom wall of the frame, and the edge of the wet film can extend into the water tank through the opening.

[0022] In a schematic embodiment, an insertion port is provided on the side wall of the housing;

[0023] The frame is slidably connected to the housing so that the support frame can slide into and out of the housing from the insertion port;

[0024] The external gear ring is provided with a second notch aligned with the first notch;

[0025] Wherein, when the first notch and the second notch rotate to face the opening, both the external gear ring and the wet film are received in the frame.

[0026] In a schematic embodiment, the driving gear is located within the frame and meshes with the side of the external gear ring facing away from the insertion port;

[0027] A relief opening is provided on the side of the frame facing away from the insertion port, and the relief opening allows the driving gear and the main shaft of the drive motor to pass through.

[0028] In a schematic embodiment, it further includes a water tank detachably connected to the housing, the water tank is provided with a water outlet communicated with the water tank, and the water tank covers the insertion port.

[0029] In a schematic embodiment, the support frame further includes a baffle covering one end of the frame;

[0030] The baffle is provided with a ventilation opening, the first support is arranged in the ventilation opening, and the wet film blocks the ventilation opening.

[0031] In a schematic embodiment, a filter screen is further included, and the filter screen is arranged in the air duct and upstream of the humidifying component;

[0034] The present application also proposes an air treatment device, which includes the wet film humidifier as described above.

[0035] In the technical solution of the present application, the driving component can drive the mounting rack and the wet film to rotate synchronously. When the wet film rotates, at least a part of the edge can enter the water tank and be immersed in the water. As the wet film continues to rotate, the wetted edge of the wet film rotates to a higher position, and the water on the edge of the wet film will quickly flow downward under the action of gravity and capillary action to gradually wet the entire wet film. The driving component can drive the mounting rack and the wet film to rotate reciprocally to repeat this process, thereby realizing rapid water addition to the wet film. When the fan drives the air in the air duct to flow through the wet film, the moisture on the wet film evaporates into the air, thereby humidifying the air.

[0036] Compared with the siphon water addition method, the method of adding water by rotating the wet film in this technical solution has a faster water addition speed. Compared with the water pump spraying water addition method, the wet film humidifier in this technical solution does not need to be provided with a water pump and supporting pipelines, has a lower manufacturing cost, is more reliable. At the same time, the method of adding water by rotating the wet film in this technical solution will not generate splashing small droplets, avoiding the small droplets being carried away by the air flow and flying out of the wet film humidifier.

Detailed implementation mode

[0052] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments and features in the embodiments of this application can be combined with each other arbitrarily.

[0053] As Figure 1 shown, Figure 1 shows a wet film humidifier 100 in this embodiment. The wet film humidifier 100 includes a housing 1, a fan 2, a humidifying component 3 and a driving component 4.

[0054] The housing 1 is a thin shell structure. An air inlet 11, an air outlet 12, an air duct 10 and a water tank 14 are arranged inside the housing 1. The housing 1 can be constructed as a generally rectangular box-shaped structure. The air inlet 11 is arranged on the top wall of the housing 1, and the air outlet 12 can be arranged on the side wall. The air inlet 11 and the air outlet 12 are respectively arranged close to the opposite sides of the housing 1. The air duct 10 extends from the air inlet 11 to the air outlet 12. The cross-section of the air duct 10 can be rectangular. The water tank 14 is arranged at the bottom of the air duct 10. The opening of the water tank 14 faces upward and is communicated with the air duct 10. The water tank 14 can be constructed as a straight strip groove, and the extending direction of the water tank 14 is perpendicular to the extending direction of the air duct 10. The water tank 14 is used to hold water.

[0055] The fan 2 is connected to the housing 1. The fan 2 is used to drive the air to flow along the extension direction of the air duct 10, and the air flow direction may be from the air inlet 11 to the air outlet 12. The fan 2 may be a centrifugal fan 2, an axial flow fan 2 or a cross-flow fan 2. The fan 2 is provided with an air inlet 211 and an air outlet 212. The air inlet 211 of the fan 2 is connected to the air outlet 12 on the housing 1. In the present embodiment, the fan 2 is a centrifugal fan 2, and the fan 2 includes a volute 21, an impeller 22 and a first motor 23. The air inlet 211 and the air outlet 212 are both provided on the volute 21. The impeller 22 is provided in the volute 21. The first motor 23 is fixed on the volute 21. The impeller 22 is sleeved on the main shaft of the first motor 23. The first motor 23 drives the impeller 22 to rotate to drive the air to flow from the air inlet 211 to the air outlet 212. The volute 21 is connected to the housing 1, and the air inlet 211 of the volute 21 is connected to the air outlet 12 of the housing 1. The volute 21 and the housing 1 may be connected by screws.

[0056] The humidifying component 3 is arranged in the air duct 10 of the shell 1. The humidifying component 3 includes a mounting frame 32 and a wet film 31. The wet film 31 is a diaphragm. The wet film 31 is made of a wet film material. The wet film 31 material uses plant fiber as the base material, and is sintered after being treated with a resin of a special component to form a corrugated plate-shaped cross-overlapping polymer composite material. It contains a sustained-release antibacterial agent and has the advantages of extremely strong water absorption, good self-cleaning ability, non-toxicity, acid and alkali resistance, mildew resistance, and flame retardancy. The wet film 31 is fixed on the mounting frame 32, and the mounting frame 32 supports the wet film 31 and flattens the wet film 31. The wet film 31 is flatly stretched by the mounting frame 32. The mounting frame 32 is configured to rotate relative to the shell 1. The rotation axis of the mounting frame 32 is perpendicular to the wet film 31 and parallel to the extension direction of the air duct 10. The humidifying component 3 is located above the water tank 14. The distance from at least a portion of the edge of the wet film 31 to the rotation axis of the mounting frame 32 is greater than the distance from the water tank 14 to the rotation axis of the mounting frame 32, so that this portion of the edge of the wet film 31 can rotate to enter the water tank 14 and contact the water in the water tank 14.

[0057] The driving assembly 4 is used to drive the mounting frame 32 to rotate. The driving assembly 4 includes a driving motor 41. The driving motor 41 is connected to the mounting frame 32 by transmission. The driving motor 41 can be connected to the mounting frame 32 by transmission mechanism, and the transmission mechanism can be a gear transmission mechanism, a belt transmission mechanism or a chain transmission mechanism. The torque output by the driving motor 41 can be transmitted to the mounting frame 32 through the transmission mechanism to drive the mounting frame 32 to rotate around its rotation axis. The driving assembly 4 can drive the mounting frame 32 to rotate and make at least a portion of the edge of the wet film 31 enter the water tank 14.

[0058] In this way, the driving component 4 can drive the mounting rack 32 and the wet film 31 to rotate synchronously. When the wet film 31 rotates, at least a part of its edge can enter the water tank 14 and be immersed in water. As the wet film 31 continues to rotate, the water-covered edge of the wet film 31 rotates to a higher position, and the water on the edge of the wet film 31 will quickly flow downward under the action of gravity and capillary action, gradually wetting the entire wet film 31. The driving component 4 can drive the mounting rack 32 and the wet film 31 to rotate reciprocally to repeat this process, thereby quickly adding water to the wet film 31. When the fan 2 drives the air in the air duct 10 to flow through the wet film 31, the moisture on the wet film 31 evaporates into the air, thereby humidifying the air.

[0059] Compared with the siphon water addition method, the method of adding water by rotating the wet film 31 in this technical solution has a faster water addition speed. Compared with the water pump spraying water addition method, the wet film humidifier 100 in this technical solution does not need to be provided with a water pump and supporting pipelines, has a lower manufacturing cost and is more reliable. At the same time, the method of adding water by rotating the wet film 31 in this technical solution will not generate splashing small droplets, avoiding the small droplets being carried away by the air flow and flying out of the wet film humidifier 100.

[0060] In a schematic embodiment, a first notch 311 is provided at the edge of the wet film 31. The distance from the edge of the wet film 31 at the first notch 311 to the rotation axis of the wet film 31 is less than the distance from the edges of other parts of the wet film 31 to the rotation axis of the wet film 31. When the wet film 31 rotates to make the first notch 311 face the water tank 14, the whole wet film 31 is outside the water tank 14 and the whole wet film 31 is above the water tank 14.

[0061] In this way, when the wet film humidifier 100 is not used for humidification, the driving component 4 can drive the mounting rack 32 to rotate until the first notch 311 of the wet film 31 faces the water tank 14, so that the whole wet film 31 is outside the water tank 14, thereby separating the wet film 31 from the water in the water tank 14. The wet film 31 is no longer continuously immersed in water, the speed of bacteria growth slows down, and the service life of the wet film 31 is prolonged.

[0062] In a schematic embodiment, the wet film 31 is set as a circular film with a first notch 311. The edge of the wet film 31 at the first notch 311 is a straight line. The wet film 31 has an arc edge outside the first notch 311 and a straight edge at the first notch 311. The central angle of the arc edge of the wet film 31 can be 200° - 300°, and the central angle of the arc edge of the wet film 31 is preferably 260°. The distance from the straight edge of the wet film 31 to the rotation axis of the wet film 31 is greater than or equal to the minimum distance from the rotation axis of the wet film 31 to the water tank 14.

[0063] In this way, the wet film 31 is generally in a D shape as a whole. When humidification is not required, the driving assembly 4 rotates the wet film 31 so that the first notch 311 of the wet film 31 faces the water tank 14. The straight edge of the wet film 31 is parallel to the extension direction of the water tank 14 and is located above the water tank 14, and the wet film 31 is separated from the water in the water tank 14. When humidification is required, the driving assembly 4 can drive the wet film 31 to rotate reciprocally so that the arc edge of the wet film 31 alternately enters the water tank 14 and is immersed in the water. Always a part of the arc edge of the wet film 31 is immersed in the water for water addition, thereby improving the water addition efficiency.

[0064] In a schematic embodiment, the driving assembly 4 further includes an external gear ring 43. A plurality of teeth are provided on the outer peripheral surface of the external gear ring 43. The mounting bracket 32 is disposed within the external gear ring 43 and is fixedly connected to the external gear ring 43. The mounting bracket 32 and the external gear ring 43 may be an integrally formed structure. The rotational axis of the external gear ring 43 and the mounting bracket 32 are coaxially arranged.

[0065] The driving assembly 4 includes a driving motor 41 and a driving gear 42. The driving motor 41 may be disposed on the housing 1, or the driving motor 41 may be disposed on the volute 21 of the blower 2. The main shaft of the driving motor 41 is coaxial with the rotational axis of the mounting bracket 32. The driving gear 42 is a cylindrical gear. The driving gear 42 is sleeved on the main shaft of the driving motor 41. The driving gear 42 is disposed outside the external gear ring 43 and meshes with the external gear ring 43. The driving assembly 4 drives the driving gear 42 to rotate, and further drives the external gear ring 43, the wet film 31 and the mounting bracket 32 to rotate synchronously.

[0066] In a schematic embodiment, the mounting bracket 32 includes a connecting cylinder 321, a plurality of spokes 322 and a plurality of reinforcing beams 323. The connecting cylinder 321 may be configured as a cylindrical shape. The connecting cylinder 321 is disposed in the middle of the external gear ring 43 and is coaxially arranged with the external gear ring 43. The spokes 322 are configured as straight bars. One end of the spoke 322 is connected to the external gear ring 43, and the other end of the spoke 322 is connected to the connecting cylinder 321. A plurality of spokes 322 are evenly distributed in a radial pattern around the connecting cylinder 321. The spokes 322 fix the connecting cylinder 321 and the external gear ring 43 together. A reinforcing beam 323 is disposed between every two adjacent spokes 322, and both ends of the reinforcing beam 323 are respectively connected to these two adjacent spokes 322. The wet film 31 is connected to the spokes 322, the reinforcing beams 323 and the external gear ring 43.

[0067] The humidifying assembly 3 further includes a support frame 33 and a rotating shaft 34. The rotating shaft 34 is connected to the connecting cylinder 321. The rotating shaft 34 may be passed through the connecting cylinder 321 of the mounting bracket 32. A clearance fit may be provided between the rotating shaft 34 and the connecting cylinder 321. The mounting bracket 32 can rotate around the rotating shaft 34. The rotational axes of the mounting bracket 32 and the wet film 31 are the central axis of the rotating shaft 34.

[0068] The support frame 33 includes a frame 331, a first support 332 and a second support 333. The frame 331 can be configured as a rectangular frame. The frame 331 is disposed in the air duct 10 and above the water tank 14. The frame 331 is connected to the housing 1. The outer peripheral wall of the frame 331 abuts against the inner peripheral wall of the air duct 10. The bottom wall of the frame 331 covers the upward opening of the water tank 14. The first support 332 is disposed at one end of the frame 331 and connected to the frame 331. The first support 332 can be configured as a straight bar, and the opposite ends of the first support 332 are respectively connected to the opposite side walls of the frame 331. The second support 333 is disposed at the end of the frame 331 opposite to the first support 332 and connected to the frame 331. The second support 333 can be configured as a straight bar, and the opposite ends of the second support 333 are respectively connected to the opposite side walls of the frame 331.

[0069] One end of the rotating shaft 34 is rotatably connected to the middle of the first support 332, and the other end of the rotating shaft 34 is rotatably connected to the middle of the second support 333. The mounting bracket 32, the external gear ring 43, and the wet film 31 are all disposed between the first support 332 and the second support 333. An opening 3311 is provided on the bottom wall of the frame 331, and the opening 3311 is a through hole penetrating the bottom wall.

[0070] In this way, the frame 331 is connected to the housing 1, the rotating shaft 34 is connected to the frame 331 through the first support 332 and the second support 333, and the mounting bracket 32 is disposed on the rotating shaft 34 and can rotate around the rotating shaft 34, so as to realize the rotation of the mounting bracket 32 relative to the housing 1. The arc edge of the wet film 31 can extend into the water tank 14 through the opening 3311 on the frame 331 and contact the water in the water tank 14. The humidifying assembly 3 has a high degree of modularity and is easy to replace and repair.

[0071] In a schematic embodiment, an insertion opening 13 is provided on the side wall of the housing 1. The insertion opening 13 penetrates the side wall. The insertion opening 13 is a rectangular opening. A first sliding groove 15 and a second sliding groove 16 are provided in the housing 1. The first sliding groove 15 and the second sliding groove 16 are respectively provided on the top wall of the air duct 10 and the bottom wall of the air duct 10. The extending direction of the first sliding groove 15 is perpendicular to the extending direction of the air duct 10 and parallel to the extending direction of the water tank 14. The water tank 14 is disposed at the bottom of the second sliding groove 16. The width of the water tank 14 is smaller than the width of the second sliding groove 16. The first sliding groove 15 and the second sliding groove 16 are in the same vertical plane and are aligned with each other. The insertion opening 13 is located at the same end of the first sliding groove 15 and the second sliding groove 16.

[0072] The top end of the frame 331 is received in the first sliding groove 15, and the bottom end of the frame 331 is received in the second sliding groove 16. The width of the frame 331 is greater than the width of the water tank 14, so that a sliding connection is formed between the frame 331 and the housing 1. The frame 331 can slide along the extending direction of the first sliding groove 15, so that the support frame 33 can slide into and out of the housing 1 from the insertion opening 13 of the housing 1.

[0073] A second notch 431 is provided on the external gear ring 43, and the second notch 431 is aligned with the first notch 311 on the wet film 31. The end of the external gear ring 43 at the second notch 431 is flush with the straight edge of the wet film 31 at the first notch 311. When the external gear ring 43 rotates until its second notch 431 faces the opening 3311 of the frame 331 and the water tank 14, the wet film 31 also rotates until its first notch 311 faces the opening 3311 of the frame 331 and the water tank 14. At this time, both the external gear ring 43 and the wet film 31 are received in the frame 331.

[0074] In this way, when the humidifying component 3 needs to be maintained, it is only necessary to control the driving component 4 to rotate the external gear ring 43 until its second notch 431 faces the opening 3311 of the frame 331, so that both the external gear ring 43 and the wet film 31 are received in the frame 331. Then, slide the frame 331 out of the housing 1 from the insertion opening 13 of the housing 1, and the entire humidifying component 3 can be withdrawn from the housing 1. Then, maintain the humidifying component 3, such as cleaning or replacing the wet film 31. Finally, insert the maintained humidifying component 3 back into the first sliding groove 15 and the second sliding groove 16 of the housing 1 from the insertion opening 13, and the installation of the humidifying component 3 is completed. The disassembly and assembly of the humidifying component 3 are more convenient.

[0075] In a schematic embodiment, the driving gear 42 is located inside the frame 331, and the driving gear 42 meshes with the side of the external gear ring 43 facing away from the insertion opening 13. A relief opening 3312 is provided on the side of the frame 331 facing away from the insertion opening 13. The main shaft of the driving motor 41 and the driving gear 42 pass through the relief opening 3312.

[0076] In this way, when the entire humidifying component 3 is slid towards the insertion opening 13, since the driving gear 42 is located on the side of the external gear ring 43 facing away from the insertion opening 13, the driving gear 42 will not interfere with the external gear ring 43 to prevent the external gear ring 43 from moving. At the same time, during the process of sliding the frame 331 out of the housing 1, the main shaft of the driving motor 41 and the driving gear 42 can pass through the relief opening 3312 on the frame 331 to avoid interference between the frame 331 and the driving gear 42.

[0077] In a schematic embodiment, the wet film humidifier 100 further includes a water tank 5. The water tank 5 is used to supply water to the water trough 14. The water tank 5 can be a flat water tank 5. The water tank 5 is detachably connected to the housing 1. The water tank 5 can be inserted into the housing 1. A water filling port is provided at the top of the water tank 5, and a water outlet is provided at the bottom of the water tank 5. The water outlet of the water tank 5 is communicated with the water trough 14 on the housing 1. The water tank 5 covers the insertion port 13 on the housing 1.

[0078] In this way, the water tank 5 can block the insertion port 13 on the housing 1, prevent air leakage from the insertion port 13, and at the same time, the water tank 5 can also prevent the humidification component 3 from detaching from the insertion port 13 of the housing 1. When the humidification component 3 needs to be maintained, the water tank 5 can also be detached from the housing 1, facilitating the disassembly and assembly of the humidification component 3.

[0079] In a schematic embodiment, the support frame 33 further includes a baffle 334. The baffle 334 covers one end of the frame 331 where the first support 332 is provided. The baffle 334 is perpendicular to the extending direction of the air duct 10. A ventilation opening 3341 is provided on the baffle 334, and the ventilation opening 3341 vertically penetrates the baffle 334. The cross-section of the ventilation opening 3341 is the same as the shape of the wet film 31. The cross-section of the ventilation opening 3341 can be set as a D-shaped cross-section. The first support 332 is provided in the ventilation opening 3341. The wet film 31 blocks the ventilation opening 3341 on the baffle 334.

[0080] In this way, since the baffle 334 is provided in the air duct 10, the air flow in the air duct 10 can only flow through the ventilation opening 3341 on the baffle 334, and the wet film 31 shields the ventilation opening 3341, so that the air flow passing through the ventilation opening 3341 will be humidified by the wet film 31, thereby improving the humidification effect of the wet film 31 on the air.

[0081] In a schematic embodiment, the wet film humidifier 100 further includes a filter screen 6. The filter screen 6 is provided in the air duct 10. Multiple filter screens 6 can be provided, and the multiple filter screens 6 can include a HEPA filter screen 61 and a manganese mesh filter screen 62. The HEPA filter screen 61 can be provided upstream of the manganese mesh filter screen 62. The HEPA filter screen 61 can filter out particulate impurities in the air. The manganese mesh filter screen 62 can be an activated manganese formaldehyde removal filter screen for removing formaldehyde in the air. The multiple filter screens 6 are all provided upstream of the humidification component 3, and the fan 2 is provided downstream of the humidification component 3.

[0082] The air in the air duct 10 flows through the filter screen 6, the wet film 31 and the fan 2 in sequence. After the impurities in the air are filtered out by the filter screen 6, they flow through the wet film 31 and the fan 2, reducing the pollution of the wet film 31 and the fan 2 by the impurities in the air and extending the service life of the wet film 31 and the fan 2.

[0083] In a schematic embodiment, a third chute 17 and a fourth chute 18 are provided inside the housing 1. The third chute 17 and the fourth chute 18 are respectively provided on the top wall and the bottom wall of the air duct 10. The extending direction of the third chute 17 is perpendicular to the extending direction of the air duct 10 and parallel to the extending direction of the water tank 14. The third chute 17 and the fourth chute 18 are in the same vertical plane and are aligned with each other. The insertion opening 13 is located at the same end of the third chute 17 and the fourth chute 18.

[0084] The top end of the filter screen 6 is received in the third chute 17, and the bottom end of the filter screen 6 is received in the fourth chute 18, so that a sliding connection is formed between the filter screen 6 and the housing 1. The filter screen 6 can slide along the extending direction of the third chute 17, so that the filter screen 6 can slide into and out of the housing 1 from the insertion opening 13 of the housing 1.

[0085] The filter screen 6 is usually a consumable and needs to be replaced or cleaned regularly. Just pull out the filter screen 6 from the insertion opening 13 to remove the filter screen 6, and insert the filter screen 6 into the third chute 17 and the fourth chute 18 from the insertion opening 13 to complete the installation of the filter screen 6. It is more convenient to replace and clean the filter screen 6.
