Description

Technical Field

[0001] The present application relates to the technical field of humidifiers, and in particular to a surround-type air duct for a humidifier. Background Art

[0002] A humidifier is a household appliance used to increase the humidity in a room or a specific space. It increases the humidity by adding moisture to the air, thereby creating a more comfortable and healthy environment for the occupants. In traditional humidifiers, since the wind cannot blow to the middle part of the humidifying structure, it can only blow to the edge of the humidifier, resulting in problems such as small evaporation area, reduced wind utilization, and small humidification amount. In order to solve the above problems, the Chinese invention patent with application number CN202311498009.5 discloses a high-efficiency humidifier, which includes a water storage part; a humidifying part, the humidifying part is arranged in the water storage part, and the humidifying part can rotate in the water storage part; a first air inlet, the first air inlet is opened in the humidifying part, and the first air inlet is used to allow wind to enter from the middle of the humidifying part and diffuse toward the edge of the humidifying part.

[0003] However, the above solution still has certain defects in actual use. The main defect is that when the wind blows from the middle to the edge, due to the characteristics of the fan blades, the wind volume of the wheel outside the humidification wheel assembly is very small. Therefore, there is still a problem that the wind cannot fully cover the humidification wheel. If the humidification amount is to be increased, the size of the fan blades needs to be increased and the number of humidification wheels needs to be increased. This will cause the size of the humidifier to increase, the machine to be bulky, and it is not convenient for users to use. Utility Model Content

[0004] In order to solve the problem in the prior art that the wind cannot fully cover the humidification wheel during operation of the existing humidifier, resulting in a small amount of air flow from the wheel, the present application provides a surround-type air duct for a humidifier.

[0005] The present application provides a humidifier surround air duct adopting the following technical solution:

[0006] A humidifier surround type air duct, comprising:

[0007] A humidifier housing is provided with at least one air inlet, the air inlet connecting the exterior of the humidifier housing with the interior cavity;

[0008] A rotor assembly is rotatably mounted in the inner cavity of the humidifier housing and has a hollow cavity therein. A plurality of ventilation gaps are provided in the circumferential direction thereof for connecting the outer space of the rotor assembly with the hollow cavity therein;

[0009] The fan is arranged on one side of the hollow cavity of the rotor assembly, with its air inlet connected to the hollow cavity and its air outlet close to the top of the humidifier housing;

[0010] When the fan is started, the air outside the humidifier casing can enter the humidifier casing from the air inlet, enter the hollow cavity of the wheel assembly along the ventilation gap of the wheel assembly, and finally be discharged to the outside of the humidifier casing through the fan.

[0011] By adopting the above technical solution, the fan is set on one side of the rotor assembly, and the external air of the humidifier is guided in sequence through the air inlet of the humidifier casing, the ventilation gap, the ventilation gap of the rotor assembly, the hollow cavity of the rotor assembly, the fan and the air outlet of the fan in an induced draft manner, so that wind can pass through each ventilation gap on the rotor assembly evenly, effectively increasing the evaporation area and doubling the humidification amount. At the same time, it also ensures the effective utilization of the rotor assembly and significantly improves the humidification efficiency.

[0012] Optionally, the air inlet is arranged at one or at least two of the upper, lower, left and right side walls of the humidifier housing.

[0013] By adopting the above technical solution, during actual operation, air can pass through the humidifier casing and enter the interior of the humidifier casing, and then directly enter the ventilation gap of the wheel assembly, which can reduce air volume loss.

[0014] Optionally, the wheel assembly includes a plurality of annular turntables that are coaxially and synchronously rotated, and the ventilation gap is located between two adjacent annular turntables.

[0015] By adopting the above technical solution, the annular turntable can facilitate the rotation of the wheel assembly inside the humidifier casing, and facilitate the rapid entry of air into the ventilation gap between two adjacent annular turntables; and since the wind enters the center from all four sides of the wheel assembly, the wind resistance is small, and the wind flows from the edge to the center of each annular turntable, the effective evaporation area is increased, the utilization rate of the wind is increased, and the humidification amount is effectively improved.

[0016] Optionally, the annular turntable at one end away from the fan is a centrally closed structure.

[0017] By adopting the above technical solution, air can be prevented from entering the hollow cavity without passing through the ventilation gap, that is, it can be ensured that air can only enter the hollow cavity after passing through the ventilation gap, which can increase the evaporation area and improve the humidification amount.

[0018] Optionally, the outer surface of the annular turntable away from one end of the fan has a gripping handle protruding outward.

[0019] By adopting the above technical solution, the convenience can be improved by holding the gripping handle during the installation and positioning of the wheel assembly, thereby increasing the flexibility of the wheel assembly during assembly. At the same time, it also avoids the problem of inaccurate positioning caused by interference of gears inside the wheel assembly, and is also beneficial for subsequent disassembly, thereby improving the efficiency of disassembly and assembly.

[0020] Optionally, the fan includes an impeller, the rotation centerline of the impeller is coaxially arranged with the centerline of the hollow cavity of the rotor assembly, and the air inlet is located at one end of the impeller close to the rotor assembly.

[0021] By adopting the above technical solution, the fan can be brought closer to the hollow cavity to improve the compactness of the overall structure of the equipment, and the air volume loss can also be reduced, so that the humidification process has the characteristics of fast wind speed and large air volume, which is conducive to improving the humidification effect.

[0022] Optionally, the fan includes a shell, and an air outlet channel extending upward is provided inside the shell, and the cross-sectional width of the air outlet channel is gradually increased from bottom to top.

[0023] By adopting the above technical solution, the humid air can be quickly diffused into the air, thereby expanding the range of humidification.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] The utility model has a reasonable design structure and adopts the method of inducing wind to guide the external air of the humidifier through the air inlet of the humidifier casing, the ventilation gap, the ventilation gap of the rotor assembly, the hollow cavity of the rotor assembly, the fan and the air outlet of the fan in sequence, forming a surround-type air duct, so that wind can pass through each ventilation gap on the rotor assembly evenly, effectively increasing the evaporation area, and doubling the humidification amount. At the same time, it also ensures the effective use of the rotor assembly, and the humidification efficiency is significantly improved.

[0026] The air intake method of this utility model can effectively control the humidification amount by simply controlling the air volume of the fan, making the control of the humidification amount more accurate and convenient. In addition, the humidification effect is improved by improving the air intake and outlet method, avoiding the problem of increasing the size of the fan impeller to improve humidification efficiency, thereby increasing the body of the humidifier. The efficiency is improved while reducing energy consumption, making the humidifier more exquisite. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The present application is further described in detail below with reference to the accompanying drawings.

[0041] like Figure 1-5 As shown, the embodiment of the present application discloses a humidifier surround air duct, comprising:

[0042] The humidifier housing 1 is provided with at least one air inlet 101, which connects the exterior of the humidifier housing 1 with the inner cavity. In this example, the air inlet 101 is provided at one or at least two of the upper, lower, left, and right side walls of the humidifier housing 1, so as to facilitate air to pass through the humidifier housing 1 and enter the interior of the humidifier. In addition, the air inlet 101 may also be provided at the top of the humidifier housing 1 to expand the range of air intake.

[0043] The rotor assembly 2 is rotatably mounted in the inner cavity of the humidifier housing 1 and has a hollow cavity 202 therein. A plurality of ventilation gaps 205 are provided in the circumferential direction thereof, connecting the outer space of the rotor assembly 2 with the hollow cavity 202 therein. The hollow cavity 202 and the ventilation gaps 205 are provided to facilitate the entry of air into the hollow cavity 202 from the ventilation gaps 205. Since the air passes through the ventilation gaps 205 and a water tank is provided below the rotor assembly 2, during its rotation, the humid air can be concentrated in the hollow cavity 202 and then discharged outward, thereby achieving the effect of humidifying the air.

[0044] The fan 3 is arranged on one side of the hollow cavity 202 of the rotor assembly 2, with its air inlet 304 communicating with the hollow cavity 202 and its air outlet 305 being close to the top of the humidifier housing 1;

[0045] Among them, when the fan 3 is started, the air outside the humidifier casing 1 can enter the inside of the humidifier casing 1 from the air inlet 101, and enter the hollow cavity 202 of the wheel assembly 2 along the ventilation gap 205 of the wheel assembly 2, and finally be discharged to the outside of the humidifier casing 1 through the fan 3.

[0046] Specifically, the wheel assembly 2 includes several coaxial and synchronously rotating annular turntables 201, and the ventilation gap 205 is located between two adjacent annular turntables 201. In this example, the surface of the annular turntable 201 has through holes 2011 evenly distributed around its center. After the through holes 2011 on all the annular turntables 201 correspond one to one, the connecting rod 203 is installed to achieve synchronous rotation connection of multiple annular turntables 201. The end of the connecting rod 203 can be axially positioned by a buckle or a nut to avoid axial movement between the annular turntables 201; in addition, the edge of the through hole 2011 of the annular turntable 201 has a convex ring 2012 protruding along its axial direction. When assembling two adjacent annular turntables 201, the end faces of the convex ring 2012 contact each other, so that the ventilation gap 205 is formed between the two adjacent annular turntables 201.

[0047] Among them, the wheel assembly 2 also includes a mechanism for realizing the rotation of the wheel assembly 2, including a ring gear that is coaxial with and fixedly connected to the wheel assembly 2, and a gear located inside the humidifier housing 1 and meshing with the ring gear. When the gear is driven by a power source such as an electric motor, the rotation of the wheel assembly 2 can be realized. The structure and principle of this part belong to conventional technical means in the existing technology and will not be elaborated here.

[0048] Specifically, the annular turntable 201 at one end away from the fan 3 is a central closed structure. Figure 7As shown, the center of the outermost annular turntable 201 of the runner assembly 2 is in a closed state, so as to prevent air from entering the hollow cavity 202 from the center of the annular turntable 201 .

[0049] Specifically, the outer surface of the annular turntable 201 away from the end of the fan 3 has a gripping handle 204 protruding outward. Figure 7 As shown, in this example, the gripping handle 204 is integrally connected to the outermost annular turntable 201, and is configured to facilitate the movement of the wheel assembly 2, thereby facilitating assembly and disassembly.

[0050] Specifically, the fan 3 includes an impeller 301, the rotation center line of the impeller 301 is coaxially arranged with the center line of the hollow cavity 202 of the wheel assembly 2, the air inlet 304 is located at one end of the impeller 301 close to the wheel assembly 2, and also includes a motor 303, which can drive the impeller 301 to rotate, thereby realizing air flow.

[0051] Specifically, the fan 3 includes a shell 302, and the shell 302 has an upward-extending air outlet channel 306, wherein the air outlet 305 of the fan 3 is located at the end of the air outlet channel 306, and the cross-sectional width of the air outlet channel 306 is gradually increased from bottom to top, so that the humid air can be quickly diffused to the outside.

[0052] This humidifier surround air duct, when working, the fan 3 acts as a power source, which can allow air to enter the humidifier from both sides of the humidifier housing 1. At the same time, the wetted annular turntable 201 rotates inside the humidifier housing 1, and the air can flow from the ventilation gap 205 between the annular turntables 201 to the central hollow cavity 202, so that the air becomes humid air. The humid air finally passes through the impeller 301 of the fan 3 and is guided upward from the air outlet channel 306 and discharged from the air outlet 305, achieving a humidification effect on the environment. During the humidification process, the ventilation gap 205 between each two adjacent annular turntables 201 can be evenly passed by wind, the effective evaporation area is increased, and the humidification amount is doubled. At the same time, controlling the humidification amount only requires controlling the air volume of the fan 3. The ventilation gap 205 between the two adjacent annular turntables 201 is small, so the wind speed is fast. Regardless of the air volume, the air volume passing through each ventilation gap 205 is uniform, thus ensuring the effective utilization of the humidification wheel and significantly improving the humidification efficiency.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
