Description

Technical Field

[0001] This utility model relates to the field of air humidification equipment technology, and in particular to a silent water tank and humidifier. Background Technology

[0002] An air humidifier is a device that increases air humidity by adding moisture to the air. It is widely used in homes, offices, hospitals, and other places. The main components of a humidifier include a water tank, a humidifying filter, and a fan. The water tank stores water, the humidifying filter humidifies the air by evaporating the water, and the fan accelerates airflow for more even humidification. The design of the water tank significantly impacts the humidifier's performance and user experience. The water tank design also affects the humidifier's noise level, especially the sound of water falling back into the tank, which can negatively affect the user experience.

[0003] Existing humidifier water tanks typically employ an open design, where water from the humidification mesh falls back into the tank by gravity. This design is simple, easy to manufacture and maintain, but the impact of the water falling back creates a noticeable dripping sound, affecting the user experience. Utility Model Content

[0004] This utility model provides a silent water tank and humidifier to solve the defect of existing humidifiers that produce loud dripping noise during water recirculation, which affects the user experience. It significantly reduces the dripping noise generated by the humidifier during water recirculation and improves the user experience.

[0005] This utility model provides a silent water tank, comprising:

[0006] A housing having a water storage cavity and an opening communicating with the water storage cavity;

[0007] The tank cover is closed to the opening. At least one water return port is provided on the outer periphery of the tank cover. The inner side wall of the tank body is provided with a drainage rib corresponding to the water return port. The drainage rib extends along the depth direction of the water storage cavity.

[0008] According to the present invention, a silent water tank is provided with multiple drainage ribs on the inner side wall of the tank body corresponding to one of the return water inlets, and the multiple drainage ribs are arranged at intervals along the width direction of the return water inlet.

[0009] According to the present invention, a silent water tank is provided in which the cross-sectional shape of the drainage rib is hemispherical.

[0010] According to the present invention, a silent water tank is provided at the return water inlet, and the guide plate is inclined downward from the center of the return water tank toward the inner side wall of the tank body.

[0011] According to the present invention, a silent water tank is provided with a horizontal step on the inner side wall of the tank body, and the lower end of the guide plate is located above the horizontal step.

[0012] According to the present invention, in a silent water tank, two drainage ribs located at the beginning and end of the water inlet extend to the step surface of the horizontal step and are higher than the step surface.

[0013] According to the present invention, a silent water tank is provided with a sound-absorbing material layer on the inner wall surface of the tank body.

[0014] According to the present invention, a silent water tank is provided with a flow guide groove on the inner side wall of the tank body, and the flow guide groove is arranged in a spiral shape.

[0015] According to the present invention, a silent water tank is provided with a plurality of water return ports on the tank cover, and a water return groove is formed on the side of the tank cover away from the tank body. The plurality of water return ports are symmetrically distributed in pairs on the periphery of the bottom of the water return groove.

[0016] This utility model also provides a humidifier, comprising:

[0017] Organism;

[0018] The silent water tank as described in any of the above claims is disposed within the body of the machine.

[0019] The silent water tank and humidifier provided by this utility model, by setting at least one return water inlet on the tank cover, prevents water returning from the humidification net from dripping directly to the bottom of the water storage chamber. Instead, the water flows into the guide ribs through the return water inlet. The design of the guide ribs allows the water to flow slowly along their surface, reducing the noise generated by water droplets directly impacting the bottom of the water tank. Therefore, this application significantly reduces the dripping noise generated by the humidifier during water return. By reducing the noise of water dripping, the humidifier is quieter during use, especially in places requiring a quiet environment, such as bedrooms and studies. This silent design greatly enhances the user experience. Users are no longer disturbed by dripping noise and can enjoy a more comfortable and peaceful environment. Attached Figure Description

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0034] The following is combined Figures 1 to 4 The silent water tank and humidifier provided by the present invention will be described in detail through specific embodiments and application scenarios.

[0035] In the embodiments of this utility model, such as Figures 2 to 4 As shown, the silent water tank 200 includes a tank body 210 and a tank cover 220. The tank body 210 has a water storage cavity 211 and an opening 212 communicating with the water storage cavity 211. The tank cover 220 closes to the opening 212. At least one return water port 222 is provided on the outer periphery of the tank cover 220. The inner side wall of the tank body 210 is provided with a drainage rib 213 corresponding to the return water port 222. The drainage rib 213 extends along the depth direction of the water storage cavity 211.

[0036] As the basic structure of the entire water tank, the tank body 210 provides space for storing water, namely the water storage chamber 211, and its design ensures the effective storage and management of water.

[0037] The tank body 210 has an opening 212 at the top, which is tightly closed by a tank cover 220. This allows users to easily add water or perform cleaning and maintenance, while also ensuring the airtightness of the internal environment of the water tank to prevent dust and other impurities from entering.

[0038] The return water trough 221 is located on the side of the tank cover 220 away from the tank body 210. The return water trough 221 is specifically used to collect water flowing back from the humidifying net. It acts as a temporary buffer area, slowing down the water flow and preventing water from directly impacting the bottom of the water tank.

[0039] At least one return water inlet 222 is provided on the bottom periphery of the return water tank 221, serving as a channel connecting the return water tank 221 and the water storage chamber 211. The return water inlet 222 ensures that the return water flows into the water tank in an orderly manner, rather than scattering randomly. By precisely controlling the flow direction of the return water, the return water inlet 222 helps maintain the stability and consistency of the water flow path, reducing the possibility of water flow dispersion, thereby reducing noise sources.

[0040] A guide rib 213, extending along the depth of the water storage chamber 211, is located on the inner wall of the tank 210, corresponding to the position of the return water inlet 222. Its main function is to guide the water flowing from the return water inlet 222 into a thin, evenly distributed stream, allowing it to slowly flow along the inner wall of the tank 210 into the bottom of the water storage chamber 211. The guide rib 213 alters the water flow pattern, making the flow smoother and reducing the impact force of the water on the bottom of the tank. This not only reduces noise but also improves the efficiency and stability of the water return process.

[0041] This application, by providing at least one return water inlet 222 on the lid 220, prevents water returning from the humidifying net from dripping directly to the bottom of the water storage chamber 211. Instead, the water flows into the guide rib 213 through the return water inlet 222. The design of the guide rib 213 allows the water to flow slowly along its surface, reducing the noise generated by water droplets directly impacting the bottom of the water tank. Therefore, this application significantly reduces the dripping noise generated by the humidifier 10 during water return. By reducing the noise of dripping water, the humidifier 10 is quieter during use, especially in places requiring a quiet environment, such as bedrooms and studies. This silent design greatly enhances the user experience. Users are no longer disturbed by dripping noise and can enjoy a more comfortable and peaceful environment.

[0042] Reference Figure 3 and Figure 4 According to the present invention, a silent water tank 200 is provided with multiple drainage ribs 213 on the inner side wall of the tank body 210 corresponding to a return water inlet 222. The multiple drainage ribs 213 are arranged at intervals along the width direction of the return water inlet 222.

[0043] Understandably, by setting multiple guide ribs 213, the returned water is further dispersed into multiple small water flow paths, rather than concentrated in one or a few paths. This dispersion effect significantly reduces the water flow intensity per unit area, reducing the pressure at individual impact points and thus effectively reducing the impact noise of water droplets on the bottom of the tank.

[0044] The drainage ribs 213 are spaced apart along the width of the return water inlet 222, ensuring that the water flowing out of the return water inlet 222 can be evenly distributed along the inner wall of the tank 210. The evenly distributed water flow not only helps to maintain the pressure balance inside the water tank, but also avoids noise problems caused by excessive local water flow concentration.

[0045] The presence of multiple guide ribs 213 increases the length and complexity of the water flow path, causing water to flow into the bottom of the water storage chamber 211 in a slower and gentler manner. The longer flow path and lower velocity mean that the impact force of the water on the bottom of the tank is significantly reduced, thereby greatly reducing the noise generated.

[0046] In some embodiments, the cross-sectional shape of the drainage rib 213 is hemispherical.

[0047] Understandably, the hemispherical cross-sectional shape effectively reduces the force of water directly impacting the bottom of the tank. As water flows along the guide rib 213, the hemispherical surface allows the water flow to smoothly change direction, thus reducing impact. Simultaneously, the hemispherical structure better absorbs and disperses the kinetic energy of the water flow, thus significantly reducing the noise generated when water impacts the bottom of the tank.

[0048] Reference Figure 2 and Figure 4 According to the present invention, a silent water tank 200 is provided with a guide plate 223 at the return water inlet 222. The guide plate 223 is inclined downward from the center of the return water tank 221 toward the inner side wall of the tank body 210.

[0049] Understandably, the design of the baffle plate 223 allows the water flowing in from the return water tank 221 to be precisely guided to the inner wall of the tank 210, avoiding disorderly diffusion of the water flow at the return water inlet 222. This orderly guidance helps reduce the direct impact of the water flow on the inner wall of the tank 210, thereby reducing noise.

[0050] Because the baffle 223 is angled downwards, it effectively extends the path of the water flow from the return water tank 221 to the inner wall of the tank 210. This extended path allows the water flow more time to decelerate before contacting the inner wall of the tank 210, thereby further reducing the noise generated by the water flow impact.

[0051] Reference Figure 3 and Figure 4 According to the present invention, a silent water tank 200 is provided, wherein a horizontal step 214 is provided on the inner side wall of the tank body 210, and the lower end of the guide plate 223 is located above the horizontal step 214.

[0052] Understandably, the design of the horizontal step 214 provides a buffer zone for the water flow from the baffle 223. As the water flows smoothly down the baffle 223 to the lower end, it encounters the horizontal step 214 and pauses and disperses there. This buffering effect helps to further slow down the water flow velocity, reduce the direct impact of the water flow on the inner wall of the tank 210, and thus reduce noise.

[0053] Reference Figure 3 According to the present invention, a silent water tank 200 has two drainage ribs 213 extending along the width direction of the return water inlet 222 and located at both ends to the step surface of the horizontal step 214 and exceeding the step surface.

[0054] Understandably, this implementation raises the two guide ribs 213 located on the two outer sides of the return water inlet 222 above the horizontal step 214, so that the return water is directly guided down from the horizontal step 214 along the guide ribs 213, thus preventing it from flowing outward.

[0055] In some embodiments, a sound-absorbing material layer is provided on the inner wall surface of the enclosure 210.

[0056] Understandably, adding a layer of sound-absorbing material inside the enclosure 210 to absorb residual faint sound can further enhance the noise reduction effect. The sound-absorbing material for this layer can be porous silicone or foam plastic, which are not only lightweight but also have good sound absorption properties.

[0057] In some embodiments, a flow guide groove is provided on the inner sidewall of the housing 210, and the flow guide groove is arranged in a spiral shape.

[0058] Understandably, by adding spiral guide grooves to the existing 213 guide ribs, a vortex-like flow path is formed, further dispersing the water flow velocity and reducing impact noise.

[0059] Reference Figure 2 According to the present invention, a silent water tank 200 is provided, and a plurality of water return ports 222 are provided on the tank cover 220. The plurality of water return ports 222 are symmetrically distributed in pairs on the periphery of the bottom of the water return tank 221.

[0060] Understandably, the multiple return inlets 222 allow the water returning from the humidifying net to be evenly distributed to different parts of the water tank, preventing the water flow from concentrating at one point and causing a large impact on the bottom of the water tank.

[0061] By symmetrically distributing multiple return water inlets 222 on the bottom periphery of the return water tank 221, the water flow velocity and impact force of each return water inlet 222 can be reduced, thereby reducing the impact of water flow on the bottom of the water tank.

[0062] The symmetrically distributed multiple return water inlets 222 help to disperse the water flow, reduce the noise caused by concentrated water flow, and improve the quiet performance of the humidifier 10.

[0063] Reference Figure 1 This utility model also provides a humidifier 10, which includes a body 100 and the aforementioned silent water tank 200 disposed within the body 100. The specific structure of the silent water tank 200 is as described in the above embodiments. It is understood that since the aforementioned silent water tank 200 is used in the humidifier 10, the embodiments of the humidifier 10 include all the technical solutions of all the embodiments disposed within the body 100, and the technical effects achieved are exactly the same, which will not be repeated here.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
