Description

Technical Field

[0001] This utility model relates to a top-fill air purifier with quiet water flow. Background Technology

[0002] Humidifiers typically consist of a blower, a water tank, and a filter assembly. They deliver humidified, clean airflow into the room by wetting the filter assembly and blowing air into it. A common wetting method involves immersing the lower end of the filter assembly in the water tank to allow it to absorb water. However, due to gravity and the filter's absorption capacity, wetting is uneven, often resulting in the lower end of the filter assembly being wet while the upper end remains dry, leading to poor wetting efficiency. Furthermore, to ensure proper wetting of the filter assembly, the water level in the tank needs to be maintained constantly, or the filter assembly needs to be made longer so that its lower end extends to the bottom of the tank. Clearly, such solutions are expensive in terms of both water replenishment and filter assembly costs, and are not environmentally friendly or energy-efficient.

[0003] In reality, we only need to keep the filter element constantly moistened, and the amount of water required to moisten it is not large. Therefore, a water pump can be used to draw water from the storage tank to the top of the filter element, allowing it to be moistened from top to bottom. This design will achieve continuous water circulation. However, when water drips from the filter element and flows back to the tank, it will inevitably produce running water noise. Therefore, a structure to reduce the running water noise also needs to be considered. Utility Model Content

[0004] This utility model proposes a top-fill water purifier with quiet water flow, aiming to solve the problems of filter element wetting and quiet return water flow. The specific technical means adopted are as follows:

[0005] A quiet, top-filled water purifier includes a housing. Inside the housing, a blower, a filter module, and a water tank are arranged from top to bottom. A water collection tray is located at the top of the housing, and the water collection tray communicates with the water tank via a water inlet channel. An air outlet grille is located around the periphery of the water collection tray. The filter module includes a filter support and a cylindrical filter. The upper part of the filter support has an annular water channel, and the bottom of the annular water channel has multiple drainage holes facing the top of the cylindrical filter.

[0024] The following is in conjunction with the appendix Figures 1 to 9 The following is a further description of the proposed solution:

[0025] This utility model of a water-flow silent top-fill air purifier includes a housing 1, an air inlet grille 11 on the housing 1, and a blower mechanism 2, a filter module 3, and a water tank 4 arranged from top to bottom inside the housing 1. A water collection tray 5 is located at the top of the housing 1, and the water collection tray 5 communicates with the water tank 4 via a water inlet channel 6. An air outlet grille 12 is provided around the periphery of the water collection tray 5. The filter module 3 includes a filter support 31 and a cylindrical filter element 32. The filter element support 31 has an annular water channel 7 on its upper part, and the bottom of the annular water channel 7 has multiple drainage holes 71 that are directly opposite the top of the cylindrical filter element 32. The top of the water storage tank 4 has a return port 41. The water storage tank 4 has a sloped guide 8 inside, the upper end of the guide 8 is opposite to the return port 41, and its lower end extends to the bottom of the water storage tank 4. The water storage tank 4 has a water pump 9 and a water inlet pipe 10 for connecting the water pump 9 and the annular water channel 6.

[0026] The top-fill water system of this product allows users to easily add water without the hassle of disassembling the water tank 4. The filter module 3 employs a top-down wetting structure, ensuring thorough, uniform, and rapid wetting. Furthermore, unlike traditional products, it eliminates the need to consider the contact dimensions between the filter module 3 and the water tank 4, thus relaxing design limitations and allowing for a smaller water tank capacity and lower water replenishment volume. Simultaneously, a sloped guide tube 8 is installed within the water tank 4 to collect backflow water, allowing it to gently fall back into the water tank 4 and reducing backflow noise.

[0027] Preferably, the slope of the guide fluid 8 is provided with multiple guide plates 81 extending along the length of the guide fluid 8. The guide plates 81 divide the slope of the guide fluid 8 into several flow channels 80. The slope includes a linear segment 801 with a first slope and a curved segment 802 that receives the linear segment 801 and extends downward in an arc. The first slope refers to the angle of the slope relative to the horizontal direction. Combined with the inner diameter and depth of the water storage tank, the first slope is generally greater than 45 degrees. The curved segment 802 serves to slow down the flow rate. The flow channels 80 in the above structure can divert the return water, reduce the flow rate of each water flow, and further reduce the noise when the water flows into the water body. The guide plates 81 located on the outermost side of the slope also prevent the return water from sliding directly out of the slope edge and entering the water body. Meanwhile, several guide ribs 82 extending along the length of the guide fluid 8 can be provided on the bottom surface of the flow channel 80. These guide ribs 82 not only further reduce the flow of water in each flow channel, but also increase the contact area between the flow channel and the water flow, which helps to reduce the water flow velocity and further reduce the noise when the water flows into the water body. The return port 41 is separated by several baffles 42, which helps to guide the return water into the corresponding flow channel 80.

[0028] This product uses a guide plate 81 and a guide rib 82 to guide the return water, allowing the return water to fall back into the water storage tank 4 more smoothly, minimizing the noise of the return water and making the purifier more suitable for use in quiet scenarios such as sleeping and reading.

[0029] Preferably, the top of the water storage tank 4 is provided with a water collection trough 43, and the bottom opening of the water injection channel 6 is connected to the water collection trough 43. Thus, after water is injected from the top, it falls into the water collection trough 43 through the water injection channel 6, and finally enters the water storage tank 4 through the return port 41. The cylindrical filter element 32 is located above the water collection trough 43. Return water drips from the lower end of the cylindrical filter element 32, flows through the water collection trough 43 and the return port 41 into the water storage tank 4. The water supply pipe 10 extends from the top of the guide tube 8 and connects to the annular water channel 7. An electrical box 44 is provided on the water collection tank 43. The lower end of the electrical box 44 extends from below the water collection tank 43. The guide tube 8 is assembled and connected to the lower end of the electrical box 44. The water pump 9 is housed in the guide tube 8, and an inlet 83 is provided at the bottom of the guide tube 8. A filter grid 84 is provided between the inlet 83 and the water pump 9 to perform simple filtration of the water pumped by the water pump 9 and isolate foreign objects. To facilitate the monitoring of the water level in the water storage tank 4 and the presence of foreign objects, the water storage tank 4 is provided with an observation window 45 for viewing the water level. The observation window 45 is located at the bottom of the water storage tank 4 and is closed by a transparent part 451.

[0030] Preferably, the filter element support 31 is provided with a plurality of circumferentially arranged support plates 311. When the cylindrical filter element 32 is fitted onto the filter element support 31, the support plates 311 abut against the inner wall of the cylindrical filter element 32. The bottom of the annular water channel 7 is supported by the top of the support plates 311. The top of the support plates 311 is provided with a snap-fit ​​position 312 that adapts to the bottom contour of the annular water channel 7.

[0031] The above preferred embodiments should be regarded as illustrative examples of the embodiments of the present application. Any technical deductions, substitutions, improvements, etc. that are similar to or based on the present application should be considered within the scope of protection of this patent.
