Description

Technical Field

[0001] The utility model relates to an air humidifier product, in particular to an upper water-adding humidifier with a hidden water injection port. Background Art

[0002] Evaporative humidifiers typically include a blower, a water reservoir, and a filter assembly. They deliver moistened, clean air into the room by wetting and blowing air through the filter assembly. Existing evaporative humidifiers typically immerse the lower end of the filter assembly in a water reservoir to allow it to absorb water. However, gravity and the filter's water absorption capacity result in uneven wetting, often with the lower end of the filter assembly wet and the upper end dry. Furthermore, to ensure proper wetting of the filter assembly, the water level in the reservoir must be maintained at all times, or the filter assembly must be lengthened so that its lower end reaches the bottom of the reservoir. Clearly, such solutions would incur high costs for both refilling and the filter assembly, making them less environmentally friendly and energy-efficient. Furthermore, most existing evaporative humidifiers still utilize a removable water tank. To refill, the tank must be removed, filled, and then reinstalled. This process is time-consuming and labor-intensive, resulting in a poor user experience. In fact, we only need to moisten the filter element assembly at all times, and the amount of water required to moisten the filter element assembly is not much, so the water replenishment method of the evaporative humidifier needs to be optimized.

[0022] The present application is further described below with reference to the accompanying drawings:

[0023] See attached Figures 1 to 10 , a top-water humidifier with a hidden water injection port, includes a shell 1, in which a blowing mechanism 2, a filter element module 3 and a water storage tank 4 are arranged from top to bottom, and a water collecting tray 5 is provided at the top of the shell 1, the water collecting tray 5 is communicated with the water storage tank 4 through a water injection channel 6, and an air outlet grid 51 is provided on the circumference of the water collecting tray 5, and a cover 7 is also provided on the water collecting tray 51, the cover 7 includes an operating part 71 and a water collection part 72, an operating control panel 8 is installed in the operating part 71, the water collection part 72 includes a concave water collection groove 721, and a recess 710 is provided on the end surface where the operating part 71 and the water collection groove 721 are connected, and a water injection port 70 connected to the water collecting tray 5 is provided in the recess 710, and a filter grid 701 is provided at the water injection port 70 of the recess 710. The filter element module 3 includes a filter element bracket 31 and a cylindrical filter element 32. The upper part of the filter element bracket 31 is provided with an annular water channel 311 and the bottom of the annular water channel 311 has multiple drainage holes 312 facing the top of the cylindrical filter element 32. The top of the water tank 4 is provided with a return port 40, and the water tank 4 is provided with a water pump 9 and an upper water pipe 90 for connecting the water pump 9 and the annular water channel 311.

[0024] The top water-adding method of this product makes it easy for users to replenish water without the trouble of disassembling the water tank. Users only need to pour an appropriate amount of water into the water filling port 70, and the water will automatically flow into the water storage tank 4 at the bottom under gravity; the water filling port 70 is cleverly hidden by the cover 7, and the water flows to the water filling port 70 in the water collection groove 721 until it disappears, making the water-adding process easier and more interesting; at the same time, the recessed position 710 at the water filling port 70 can also serve as a handle for the humidifier, making it easier for users to carry and move it. Compared with the traditional handles on both sides of the shell, this is not only more beautiful and does not require holes to be opened on the shell, but is also located on the central axis of the humidifier, so that users can lift it with one hand.

[0025] Specifically, the operating portion 71 includes a top plate 711 and an end plate 712 bent downward from the edge of the top plate 711 and connected to the water collection channel 721. The operating portion 711 also includes a mounting member 713. The mounting member 713 includes a chamber for accommodating the operating control panel 8, with a sealing ring 10 disposed between the top opening of the chamber and the top plate 711. The bottom of the mounting member 713 is provided with an upper wiring opening 714 connected to the chamber. The water collection pan 5 is provided with a lower wiring opening 52 that docks with the upper wiring opening 714. The lower wiring opening 52 is connected to the interior of the housing 1, and a sealing ring 10 is also disposed between the lower wiring opening 52 and the upper wiring opening 714. Due to structural limitations, the mounting member 713 is located inside the water collection tray 5, which makes it difficult to avoid being invaded by water vapor. At the same time, the wires of the operating control panel 8 need to be connected to the blower mechanism 2 and other devices inside the shell 1 through the upper wiring port 714 and the lower wiring port 52. The lower wiring port 52 is located at the bottom of the water collection tray 5, so the sealing ring 10 can better isolate water vapor and prevent water leakage. The mounting member 713 is provided with a lifting member 715, and the lifting member 715 is formed with the recess 710, and the end plate 712 is provided with a notch that matches the recess 710. This is equivalent to integrating the traditional handle structure with the water injection structure, which not only achieves the effect of hiding the water injection port 70, but also caters to the user's carrying habits and uses it as a handle, which provides a better user experience.

[0026] Taking into account the beautiful appearance of the product, according to actual production needs, the end plate 712 is vertical or inclined toward the water collection trough 721, so that the top plate 711 can better cover the water inlet 70, and the visual effect of the water flow disappearing after injection is also better.

[0027] The water injection channel 6 includes a first drainage section 61 extending from the bottom of the water collecting tray 5, a second drainage section 62 provided on the volute 21 of the blower mechanism 2, and a third drainage section 63 provided on the filter element bracket 31. The first drainage section 61, the second drainage section 62 and the third drainage section 63 are connected in sequence. The top of the water storage tank 4 is provided with a water collecting trough 41, and the water collecting trough 41 has a reflux port 40 connected to the interior of the water storage tank 4. The filter element bracket 31 is provided above the water collecting trough 41. The bottom end opening of the third drainage section 63 leads to the water collecting trough 41. The water injection channel 6 adopts a three-section design to facilitate the molding and disassembly of each component. See the attached Figure 10 As shown by the arrows, the user adds water to the water collection trough 721, and the water flows into the water collection tray 5 through the water inlet 70, and then flows into the water collection trough 41 of the water storage tank 4 through the first drainage section 61, the second drainage section 62 and the third drainage section 63, and finally enters the water storage tank 4 through the return port 40. Similarly, the water drained from the filter element module 3 also drips into the water collection trough 41, enters the water storage tank 4 through the return port 40, and is circulated through the filter element module 3 and the water storage tank 4 by the operation of the water pump 9. This top-down wetting structure not only wets fully, evenly and quickly, but also does not need to consider the contact size between the filter element and the water storage tank as in traditional products, thus relaxing the design limitations of the product structure. The water tank capacity can be smaller, and the water replenishment amount can also be smaller. The sufficient wetting and reduced water replenishment amount mean that the water pump 9 can also use a smaller power pump, which saves energy and reduces noise.

[0028] The above preferred embodiments should be regarded as examples of the implementation methods of the present application scheme. Any technical deductions, replacements, improvements, etc. that are identical or similar to the present application scheme or made based on it should be regarded as within the scope of protection of this patent.
