Description

Technical Field

[0001] This invention relates to the field of humidification device technology, and specifically provides a humidification device and an air conditioner including the humidification device. Background Technology

[0002] With the development of technology and the improvement of people's living standards, air conditioners have become widely used, and people's requirements for their functions are also increasing. For example, in addition to the conventional air temperature regulation function, many air conditioners now have additional air conditioning modules such as humidification and purification to regulate the indoor air environment. However, currently, these additional air conditioning modules are generally built into the indoor unit. The indoor unit performs humidification and purification operations simultaneously while exchanging heat with the air. Therefore, humidification and purification operations only regulate the air entering the indoor unit's area and then radiate to other parts of the room through the indoor unit's exhaust. Since the indoor unit generally operates in a fixed location, it cannot guarantee the air quality at the user's location, affecting the user's comfort experience. Therefore, existing technology uses movable sub-units to regulate the air in locations farther from the indoor unit. However, existing sub-units generally increase humidity by mixing water mist generated by ultrasonic vibration with purified air before releasing it into the room. However, the high humidity is difficult to control, resulting in large fluctuations in indoor air humidity, thus reducing the user experience.

[0003] Accordingly, there is a need in the field for a new humidification device to address the problem that existing air conditioner unit humidification devices cannot meet users' comfortable humidity requirements. Summary of the Invention

[0004] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that existing air conditioner sub-unit humidification devices cannot meet users' comfortable humidity requirements.

[0005] In a first aspect, the present invention provides a humidification device, the humidification device comprising a water tank, a fan blade, a rotating water jacket, a drive device, and a wet film, wherein the rotating water jacket is provided with a cavity, the drive device is drivenly connected to the fan blade to drive the fan blade to rotate, the rotating water jacket is connected to the fan blade and placed inside the water tank, the fan blade is provided with a spray hole, the wet film is disposed above the water tank, and water in the water tank enters the cavity and forms water mist under the action of centrifugal force to wet the wet film.

[0006] When the above technical solution is adopted, water in the water tank is drawn into the water jacket cavity. The water in the cavity is dispersed into a water mist under centrifugal force, and further refined as it is forced through the spray holes on the fan blades. The water mist evenly wets the wet film above the water tank, thus carrying away moisture from the wet film as purified air passes through it, increasing the moisture content in the air and consequently increasing indoor humidity. Compared to directly spraying the wet film, wetting it with water mist significantly improves the uniformity of wetting, avoids over-humidification, and helps maintain the stability of indoor air humidity, preventing localized excessive humidification or dryness.

[0007] In the optional technical solution of the above-mentioned humidification device, the humidification device further includes a rotating shaft, which is connected to the driving device in a transmission manner. The water tank is provided with an upwardly extending mounting part, which is provided with a hollow part. The rotating shaft passes through the hollow part and is connected to the fan blade. The mounting part is located in the cavity.

[0008] With the above technical solution, the motor is located outside the water tank, one end of the shaft is connected to the motor drive, and the other end is inserted into the hollow part and connected to the fan blade inside the water tank, thereby reducing the corrosion of the shaft by water.

[0009] In the optional technical solutions of the above-mentioned humidification device, the humidification device further includes a bearing, and the rotating shaft and the mounting part are connected by the bearing.

[0010] When the above technical solution is adopted, the shaft and the mounting part are connected by a bearing, thereby improving the stability of the fan blades during rotation.

[0011] In the optional technical solutions of the above-mentioned humidification device, the rotating water jacket is inverted conical in shape.

[0012] When the above technical solution is adopted, the inverted conical design of the rotating water jacket enables the water mist to be distributed in a conical shape, so that the water mist can contact the wet film evenly, thereby improving the contact area and uniformity.

[0013] In the optional technical solutions of the above-mentioned humidification device, the wet film is U-shaped and surrounds the top end face of the water tank.

[0014] When the above technical solution is adopted, the wet film is U-shaped and surrounds the top end face of the water tank, which can both increase the surface area of ​​the wet film and save space.

[0015] In the optional technical solutions of the above-mentioned humidification device, the humidification device further includes a housing, the housing is provided with a receiving cavity, the water tank is removably disposed in the receiving cavity, and the housing is provided with an air inlet and an air outlet.

[0016] With the above technical solution, the water tank can be pulled out and installed in the receiving cavity, which makes it easy to add water to the water tank.

[0017] In the optional technical solutions of the above-mentioned humidification device, the humidification device further includes a purification module and a fan. The fan and the purification module are disposed in the housing. The fan, the purification module and the wet membrane are connected by an air duct. The air is purified in the purification module and then humidified by the wet membrane before being discharged from the air outlet.

[0018] When the above technical solution is adopted, the purification module purifies the indoor air and then humidifies it through a wet film before expelling it from the air outlet to improve air quality.

[0019] In the optional technical solutions of the above-mentioned humidification device, a rotatable air guide plate is provided on the air outlet.

[0020] With the above technical solution, the air direction can be adjusted by the flip-up air deflector to improve the user experience.

[0021] In the optional technical solution of the above-mentioned humidification device, a protrusion extends upward from one end face of the water tank, and the wet film is disposed on the other end face of the water tank, so that when the water tank is pushed into the receiving cavity, the protrusion blocks the wet film inside the housing.

[0022] When the above technical solution is adopted, the wet film is set on the water tank and the protrusion and the shell together surround the wet film in the receiving cavity, so as to improve the integration of the device and reduce the volume.

[0023] The present invention also provides an air conditioner, the air conditioner including an indoor unit and a sub-unit, the sub-unit including the humidification device described in any of the above technical solutions, the indoor unit being provided with a housing compartment, and the sub-unit being able to enter and exit the housing compartment.

The rotating water jacket is provided with a cavity. The drive device and the fan blade are connected to drive the fan blade to rotate. The rotating water jacket is connected to the fan blade and placed inside the water tank. The fan blade is provided with spray holes. The wet film is placed above the water tank. Water in the water tank enters the cavity and forms water mist under the action of centrifugal force to wet the wet film.

[0025] With the above technical solution, the working principle of the humidification device of the present invention is as follows: the drive device outputs power to drive the fan blades to rotate at high speed. The fan blades drive the rotating water jacket to rotate at high speed. Water in the water tank is drawn into the cavity of the water jacket. Under the action of centrifugal force, the water in the cavity is dispersed into water mist, and further refined when forced through the spray holes on the fan blades. The water mist evenly wets the wet film above the water tank, thereby carrying away the moisture on the wet film when the air passes through it, increasing the moisture content in the air, and thus increasing the indoor humidity. Compared with directly spraying the wet film, the method of wetting the wet film by water mist can significantly improve the uniformity of wetting the wet film, avoid over-humidification, and the wet film can help maintain the stability of indoor air humidity, avoiding localized excessive humidity or dryness.

Detailed Implementation

[0037] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, although this application is described in conjunction with an air conditioner, this is not limiting; the humidifier device of the present invention can also be applied to other household appliances, such as washing machines, dryers, refrigerators, fans, etc., and can also be applied to other devices that require a humidifier unit.

[0038] It should be noted that in the description of this invention, the terms "upper," "lower," "inner," "outer," etc., which indicate the direction or positional relationship, are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and is not intended to indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention.

[0039] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0040] Reference Figures 1 to 5 To address the problem that existing air conditioner humidification devices cannot meet users' comfortable humidity requirements, the humidification device of this invention includes a water tank 1, a fan blade 2, a rotating water jacket 3, a drive device 4, and a wet film 5. The rotating water jacket 3 is provided with a cavity 31. The drive device 4 is connected to the fan blade 2 to drive the fan blade 2 to rotate. The rotating water jacket 3 is connected to the fan blade 2 and placed inside the water tank 1. The fan blade 2 is provided with spray holes 21. The wet film 5 is placed above the water tank 1. Water in the water tank 1 enters the cavity 31 and forms water mist under centrifugal force to wet the wet film 5. Figure 5 The middle arrow indicates the direction of water flow.

[0041] The advantages of the above-described configuration are as follows: The working principle of the humidification device of the present invention is that the drive device 4 outputs power to drive the fan blade 2 to rotate at high speed. The fan blade 2 drives the rotating water jacket 3 to rotate at high speed. The water in the water tank 1 is drawn into the cavity 31 of the water jacket. Under the action of centrifugal force, the water in the cavity 31 is dispersed into water mist, and further refined when forced through the spray holes 21 on the fan blade 2. The water mist evenly wets the wet film 5 above the water tank 1 from bottom to top. After absorbing the water, the wet film material forms a uniform water film, thereby carrying away the moisture on the wet film 5 when the air passes through it, increasing the water content in the air and thus increasing the indoor humidity. Compared with directly spraying the wet film 5, the method of wetting the wet film 5 by water mist can significantly improve the uniformity of wetting the wet film 5, avoid over-humidification, and the wet film 5 can help maintain the stability of indoor air humidity, avoiding local over-humidification or dryness.

[0042] In one possible implementation, the present invention provides an air conditioner, which includes an indoor unit and a sub-unit, wherein the indoor unit is provided with a housing compartment, and the sub-unit can enter and exit the housing compartment.

[0043] Reference Figures 1 to 5 Furthermore, the sub-unit includes a humidification device, which includes a water tank 1, a fan blade 2, a rotating water jacket 3, a drive unit 4, a wet film 5, a rotating shaft 41, a bearing 42, and a housing 6, as shown in the reference. Figure 1 The side of the shell 6 is provided with a receiving cavity 61, and the water tank 1 is removably installed in the receiving cavity 61 to facilitate the filling of water into the water tank 1. (Continue referring to...) Figure 1 and Figure 4 The top of the water tank 1 has four end faces. The wet film 5 is U-shaped and surrounds three of the end faces of the top of the water tank 1. A protrusion 12 extends upward from the other end face so that when the water tank 1 is pushed into the shell 6, the protrusion 12 blocks the wet film 5 inside the shell 6. (Refer to...) Figure 1 A transparent part 13 is provided on the outside of the water tank 1 so that the user can see the water level in the water tank 1 from the outside of the humidifier.

[0044] Continue to refer to Figure 3 and Figure 5 Furthermore, an upward-extending (mist-emitting direction) mounting portion 11 is formed in the middle of the interior of the water tank 1. The mounting portion 11 has an upward-extending hollow portion 111. The drive device 4 can be a motor, which is located outside the water tank 1. One end of the rotating shaft 41 is connected to the motor for transmission, and the other end passes through the hollow portion 111 and is connected to the fan blade 2 inside the water tank 1, minimizing contact between the rotating shaft 41 and the water, thereby reducing water corrosion of the rotating shaft 41. The rotating shaft 41 and the mounting portion 11 are connected by a bearing 42, thereby improving the stability of the fan blade 2 when rotating.

[0045] Continue to refer to Figure 5Furthermore, the rotating water jacket 3 is an inverted cone shape, wider at the top and narrower at the bottom, and is connected to the fan blade 2 in an inverted manner, as shown in the reference. Figure 3 The fan blade 2 is equipped with a water spray hole 21. (Continue referring to...) Figure 5 The rotating water jacket 3 is provided with a cavity 31, and the mounting part 11 is located inside the cavity 31. The rotating water jacket wall surrounds the mounting part 11. There is a certain gap between the lower edge of the rotating water jacket 3 and the bottom of the water tank 1, so that when the rotating water jacket 3 rotates, the water in the water tank 1 can be drawn into the cavity 31 through the gap and refined into water mist under the action of centrifugal force. The inverted conical design of the rotating water jacket 3 enables the water mist to be distributed in a conical shape, so that the water mist is in uniform contact with the wet film 5, improving the contact area and uniformity.

[0046] It should be noted that the wet film 5 can be disposed not only on the water tank 1, but also inside the housing 6. Thus, after the water tank 1 is pushed into the receiving cavity 61, the wet film 5 is positioned above the water tank 1. Therefore, those skilled in the art can set the placement of the wet film 5 as needed, as long as the water mist can contact the wet film 25. This invention does not impose any restrictions on this, and all such placements fall within the protection scope of this invention. It should also be noted that those skilled in the art can set the material and shape of the wet film 5 as needed. It can be a sponge-type wet film, a filter paper-type wet film, or a resin fiber wet film, etc. Its shape can also be a hollow cylinder or a cuboid, etc. This invention does not impose any restrictions on the material and shape of the wet film 5, as long as the wet film material can absorb water and evaporate easily, all of which fall within the protection scope of this invention. Furthermore, this invention does not impose any restrictions on the shape and number of the spray holes 21, as long as the water mist can pass through the spray holes 21 and contact the wet film 5. Those skilled in the art can set its shape and number as needed, and all of these fall within the protection scope of this invention.

[0047] Furthermore, the humidification device also includes a purification module and a fan (not shown in the figure). The fan, purification module, and wet membrane 5 are connected via an air duct, as shown in the figure. Figure 1 and Figure 2 The housing 6 is provided with an air inlet 64 and an air outlet. The air inlet 64 is located on the periphery of the housing 6, and the air outlet is located on the top of the housing 6. The fan and purification module are located inside the housing 6. When the fan is turned on, the air entering the housing 6 through the air inlet 64 is purified by the purification module, then humidified by the wet membrane 5, and finally discharged outside the housing 6 through the air outlet. The purification module can be activated carbon or a filter element, etc., capable of filtering dust, harmful substances, etc. in the air. It should be noted that the present invention does not impose any limitations on the shape of the housing 6. It can be a cylindrical shape such as a circle, square, or trapezoid. Those skilled in the art can set the shape of the housing 6 as needed, and all such designs fall within the protection scope of the present invention.

[0048] Furthermore, the air inlet 64 is configured as a circular micropore, with multiple micropores arranged in a sheet on the housing 6. This not only prevents larger foreign objects from being sucked into the housing 6 but also improves air intake efficiency. However, this invention does not impose any limitations on the shape and number of the air inlet 64. The shape of the air inlet 64 can also be square, elliptical, rhomboid, triangular, etc., and the number of air inlets 64 can be one or multiple. Those skilled in the art can set the shape and number of the air inlets 64 as needed, and all such settings fall within the protection scope of this invention.

[0049] Reference Figure 6 Furthermore, the air outlet includes a side air outlet 62 and a top air outlet 63. The side air outlet 62 is located on the side of the housing 6, and the airflow direction is outward from the side of the housing 6. The top air outlet 63 is located on the top of the housing 6, and the airflow direction is upward towards the housing 6. Multiple side guide vanes 65 are fixedly installed on the side air outlet 62, and multiple top guide vanes 66 are installed on the top air outlet 63. The side guide vanes 65 and top guide vanes 66 are used to adjust the airflow direction. Optionally, the housing 6 has four faces in different directions, and one or more rectangular side air outlets 62 are provided on each face, so that the air can blow in different directions, which can make the airflow more evenly distributed and the flow distance longer. The top air outlet 63 is annular. The combination of the air outlets on the four sides and the annular air outlet at the top can optimize air circulation. This three-dimensional air circulation mode can ensure a more uniform distribution of indoor air and guarantee the air quality of the entire space. However, it should also be noted that those skilled in the art can also set the number and shape of the side air outlets 62 and the top air outlets 63 as needed, and all of these fall within the protection scope of this invention.

[0050] Reference Figure 7 The side air guide vane 65 has an angle α with the horizontal direction, where 65° ≥ α ≥ 30°. The smaller the angle between the side air guide vane 65 and the horizontal direction, the closer the airflow direction is to horizontal, which helps with directional airflow, reduces wind noise, and improves indoor quietness. The larger the angle between the side air guide vane 65 and the horizontal direction, the more oblique the airflow direction is, avoiding direct airflow towards the user and improving comfort. Optionally, the angle α between the side air guide vane 65 and the horizontal direction can be 35°, 40°, 50°, 55°, 60°, etc. Preferably, the angle α is 50°. The spacing between each side air guide vane 65 is greater than or equal to 3mm and less than or equal to 6mm. Optionally, the spacing between the side air guide vanes 65 can be 3.5mm, 4mm, 4.2mm, 5mm, 5.5mm, etc. Preferably, the spacing between the side air guide vanes 65 is 4.2mm.

[0051] The length of the side air guide 65 is greater than or equal to 90 mm and less than or equal to 130 mm. The length of the side air guide 65 is 95 mm, 100 mm, 105 mm, 110 mm, 120 mm, etc., and preferably, the length of the side air guide 65 is 110 mm.

[0052] The greater the length and spacing of the side guide vanes 65, the greater the airflow and the smaller the propagation distance, and vice versa. By adjusting these two aspects to a suitable range, the airflow and propagation distance can be guaranteed to improve user comfort.

[0053] The length of the top guide vane 66 and the spacing between adjacent top guide vanes 66 are the same as those of the side guide vanes 65. The angle between the top guide vane 66 and the vertical direction is the same as the angle α between the side guide vane 65 and the horizontal direction. Of course, those skilled in the art can also set the tilt angle, length, and spacing of the side guide vanes 65 and the top guide vanes 66 as needed. This invention does not impose any limitations on this, and all such settings fall within the protection scope of this invention.

[0054] Reference Figure 6 In another embodiment, a side guide vane 65 is rotatably mounted on the side air outlet 62. Its tilt direction can be adjusted by rotating the side guide vane 65, thereby adjusting the airflow direction. Specifically, the side guide vane 65 is connected to a drive motor via a transmission member, so that the drive motor drives the side guide vane 65 to rotate and adjust its tilt angle. Optionally, a top guide vane 66 is rotatably mounted on the top air outlet 63. The top guide vane 66's tilt direction can be adjusted by rotating it, thereby adjusting the airflow direction. Specifically, the top guide vane 66 is also connected to a drive motor via a transmission member, so that the drive motor drives the top guide vane 66 to rotate and adjust its tilt angle.

[0055] Reference Figure 8 Furthermore, universal casters 67 are respectively provided at the four corners of the bottom of the housing 6. When the user drags the sub-unit, the sub-unit is moved by the casters 67, so that the sub-unit can be moved easily without the need for lifting or dragging, and the frictional resistance is small, maintaining smooth movement. However, the number of casters 67 is not limited to four. Those skilled in the art can set the number of casters 67 as needed, and it can also be five, six, eight, etc. The structure of the casters 67 can also be set by those skilled in the art, and all of them fall within the protection scope of this invention. Optionally, the sub-unit is provided with a drive system connected to the casters 67. The drive system drives the casters 67 to rotate so that the sub-unit can move automatically. Those skilled in the art can set the structure of the sub-unit as needed, and all of them fall within the protection scope of this invention.

[0056] In summary, the sub-unit of this invention uses an inverted conical rotating water jacket 3 to draw in water and generate water mist under centrifugal force. This increases the contact area between the water mist and the wet film 5, as well as the uniformity of wetting the wet film, preventing over-humidification of the wet film 5. Furthermore, indoor air carries away the moisture from the wet film to humidify the room, helping to maintain stable indoor humidity and preventing excessive humidity or dryness. Further, the airflow direction is adjusted by the air guide plate on the housing 6, allowing the sub-unit to adjust the airflow direction according to user needs when moving detached from the main unit, thus improving user comfort during room air purification and humidification.

[0057] As described in the first paragraph of this section, the above embodiments are merely used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above structure so that the present invention can be applied to more specific application scenarios.

[0058] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
