Abstract
Description
Technical Field
[0001] The utility model relates to an upper water-adding evaporative humidifier. Background Art
[0002] Various types of humidifiers are used to increase the humidity of indoor air, including evaporative humidifiers. Evaporative humidifiers usually include a blower, a water reservoir, and a filter assembly, which wets and blows the filter assembly to deliver moist, clean air to the room.
[0003] The evaporative humidifier in the prior art usually immerses the lower end of the filter element assembly into a water reservoir to allow it to absorb water. However, due to the influence of gravity and the water absorption capacity of the filter element, the wetting is uneven, and the lower end of the filter element assembly is often wet and the upper end is dry. At the same time, in order to ensure the infiltration of the filter element assembly, it is necessary to always maintain the water level in the water reservoir, or to lengthen the filter element assembly so that its lower end can extend to the bottom of the water reservoir. Obviously, this kind of solution will have high water replenishment costs and filter element assembly costs, which is not environmentally friendly and energy-saving. In addition, most of the existing evaporative humidifiers still use a structure with an externally detachable water tank. When it needs to be replenished with water, the water tank can be removed, filled with water, and then reinstalled. The water replenishment process is time-consuming and labor-intensive, and the user experience is poor. 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 it is necessary to optimize the water replenishment method of the evaporative humidifier.

[0025] Combine the following Figures 1 to 10 , further describe this application scheme:
[0026] The upper water-added evaporative humidifier includes a body 1, and air is discharged at the top of the body 1 and air is inletted at the side of the body 1, that is, an air outlet is arranged at the top of the body 1, and an air inlet (such as a shell with a porous grid) is arranged at the side of the body 1; the interior of the body 1 is provided with a blower mechanism 2, a filter element module 3 and a water tank 4 from top to bottom, a water injection port 10 is arranged at the top of the body 1, and the water injection port 10 is connected with the water tank 4 through a water injection channel 5 inside the body 1, the filter element module 3 includes a bracket 31, a cylindrical filter element cotton 32 installed on the bracket 31, and an annular water channel 33 arranged above the bracket 31, the bottom of the annular water channel 33 is provided with a plurality of drainage holes 330 facing the top of the cylindrical filter element cotton 32, and the water tank 4 A reflux hole 40 is provided on the top cover 41, and a water pump 61 and an upper water pipe 62 connecting the water pump 61 and the annular water channel 33 are provided in the water tank 4. When started, the water pump 61 pumps the water in the water tank 4 to the annular water channel 33, and then drips the water to the cylindrical filter cotton 32 through the drainage hole 330 of the annular water channel 33. 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 module 3 and the water tank 4 as in traditional products, relaxes the design limitations of the product structure, and makes the water tank capacity smaller and the water replenishment amount smaller (often a cup of water can be maintained, and there is no need to fill the water tank). The sufficient wetting and the reduced water replenishment amount mean that the water pump 61 can also use a smaller power water pump, which saves energy and reduces noise. At the same time, this product adopts an upper water-adding structure with a water filling port 10 designed at the top of the body 1. The user only needs to pour an appropriate amount of water into the water filling port 10, and the water will automatically flow into the water tank 4 at the bottom under gravity, eliminating the trouble of disassembling and assembling the water tank of traditional products. The filling process is easier and more interesting, effectively improving the user experience.
[0027] Specifically, the air inlet 21 of the blowing mechanism 2 is located at the bottom thereof and is connected to the central channel 320 of the cylindrical filter cotton 32. The top of the blowing mechanism 2 is provided with a water receiving tray 22 connected to the water filling port 10, and the bottom of the water receiving tray 22 is connected to the water filling channel 5. The blowing mechanism 2 has an annular air outlet 23 surrounding the water receiving tray 22. The annular air outlet 23 is provided with a plurality of inclined air guide plates 24 to form a divergent blowing airflow. The top of the fuselage 1 is provided with an air outlet grid 11 adapted to the annular air outlet 23. In order to have a certain load capacity and facilitate the user to perform water replenishment operations, the middle part of the air outlet grid 11 is concave to form a water collection trough 12, and the water filling port 10 is provided at the bottom of the water collection trough 12. The air outlet grid 11 is provided with an operating table 13 extending from its outer edge to the top of the water collection tank 12, and an operation display panel is provided on the operating table 13. The water inlet 10 is located below the operating table 13 and is provided with a filtering grid. When the user pours a large amount of water, the water will be carried in the water collection tank 12 and gradually flow into the water inlet 10, and the water inlet 10 is blocked from above by the operating table 13, which has a beautiful structure and makes the water filling process interesting and creative.
[0028] Furthermore, the bottom of the water receiving tray 22 extends laterally to have a docking joint 221 for connecting with the water injection channel 5, the docking joint 221 is connected to the inside of the water receiving tray 22, and the plate surface 222 of the water receiving tray 22 is inclined toward the docking joint 221 to allow water to flow to the docking joint 221. The water injection channel 5 includes a first drainage section 51 located in the volute 201 of the blower mechanism 2 and a second drainage section 52 connecting the first drainage section 51 and the water tank 4, the upper end of the first drainage section 51 is connected to the docking joint 221 of the water receiving tray 22, the top cover 41 of the water tank 4 is provided with a water collecting tray 42, the center of the water collecting tray 42 is connected to the inside of the water tank 4 (i.e., the reflux hole 40), and the lower end of the second drainage section 52 extends into the water collecting tray 42 and is provided with a water outlet 521 facing the center of the water collecting tray 42. The water collecting pan 42 receives the water added by the water injection channel 5 to flow into the water tank 4 to achieve water replenishment. The water collecting pan 42 also receives the water that drains back through the filter element module 3 for recycling. Considering the assembly and disassembly of the product, the water injection channel 5 is split into several sections that are integrated with each main module. On the one hand, the internal structure of the fuselage 1 is fully utilized, and on the other hand, it is more convenient to disassemble.
[0029] To facilitate assembly and docking, a coupler is used for the product's line connection. A coupler assembly 7 and an electrical box assembly 8 integrated in the water tank 4 are provided in the body 1. The coupler assembly 7 includes a coupler socket 71, a coupler socket fixing frame 72, a coupler plug 73 and a coupler plug fixing frame 74. The coupler plug fixing frame 74 is fixed to the outer shell of the fuselage 1, and is provided with a power jack 75 and a temperature sensor 76.
