Description

Technical Field

[0001] The utility model relates to the field of humidifiers, in particular to a wind wheel type humidifier. Background Art

[0002] Air humidity is one of the important factors affecting environmental comfort, especially in northern regions and dry places where air conditioners are often used. Therefore, humidifiers have become a must-have small appliance for many families.

[0003] In the prior art, a wind wheel humidifier is provided, which includes a casing, a fan and a wet film in the shape of a circular column. The casing is provided with an air inlet and an air outlet. The wet film is installed in the casing, and the impeller of the fan is installed on the inner side of the wet film. When the fan is started, it can drive external air into the casing from the air inlet, pass through the wet film and enter the fan, and be discharged after being pressurized by the fan, and then be discharged from the air outlet after being humidified by the wet film again. When the air passes through the wet film, it will take away the water on the wet film to achieve humidification.

[0004] When the impeller humidifier is in use, air passes through the wet film in the radial direction of the wet film to enter the fan, and then passes through the wet film in the radial direction of the wet film to be discharged from the air outlet. However, the wet film is in the shape of a circular column, which will hinder the air from passing through the wet film, resulting in a large loss of air volume from the fan, greatly reducing wind force, making it difficult to carry away water on the wet film, thereby affecting the humidification effect.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] The utility model provides a wind wheel type humidifier, which is used to solve the problem of how to reduce the air volume loss of the fan 3 and increase the amount of water brought out by the fan 3.

[0032] See also Figure 1 and Figure 2 As shown, Figure 1 It is a three-dimensional diagram of the wind wheel humidifier in the embodiment. Figure 2 1 is a cross-sectional view of a wind wheel type humidifier in an embodiment, wherein the wind wheel type humidifier comprises a casing 1 , a water wheel 2 and a fan 3 .

[0033] The housing 1 is provided with an air inlet 11 and an air outlet 12 .

[0034] The water wheel 2 is installed in the casing 1, and the water wheel 2 includes at least two water-absorbing blades 21. There is an air duct 22 between adjacent water-absorbing blades 21. The air duct 22 is opposite to and connected with the air inlet 11, and the air duct 22 is opposite to and connected with the air outlet 12.

[0035] The fan 3 is installed at the air outlet 12 of the housing 1 , and is used to drive air to flow from the air inlet 11 into the air duct 22 and then flow toward the air outlet 12 .

[0036] When the wind wheel humidifier of the above technical solution is used, the fan 3 is started, driving the external air to flow into the casing 1 from the air inlet 11, and then flowing toward the air outlet 12 through the air duct 22. When the air passes through the air duct 22, it can drive the water on the water absorbing blades 21 to leave the water absorbing blades 21 and flow toward the air outlet 12. When the water passes through the fan 3, it is dispersed by the fan 3 to form water mist, and blown out of the humidifier to achieve humidification. During the humidification process, since the air duct 22 is relative to and connected to the air inlet 11, and the air duct 22 is also relative to and connected to the air outlet 12, the wind flow formed by the fan 3 can flow to the air outlet 12 through the air duct 22 without passing through multiple turns, effectively reducing the air volume loss of the fan 3, ensuring that the wind force of the fan 3 is sufficient to take away a large amount of water on the water absorbing blades 21, thereby improving the humidification effect. Furthermore, the at least two water-absorbing blades 21 distributed at intervals can form a plurality of air passages 22 , thereby increasing the contact area between the wind flow and the water wheel 2 , thereby increasing the amount of water brought out by the wind flow passing through the water wheel 2 .

[0037] See also Figure 2 As shown, in one embodiment of the casing 1, the casing 1 includes an air inlet baffle 13 and an air outlet baffle 14, the air inlet baffle 13 can be welded or integrally connected to the air inlet 11 of the casing 1, and the air inlet baffle 13 and the inner wall of the casing 1 are enclosed to form a first air duct 15, the first air duct 15 connects the air inlet 11 and the air duct 22, the air outlet baffle 14 can be welded or integrally connected to the casing 1, and is located between the water wheel 2 and the fan 3, and a second air duct 16 is opened on the air outlet baffle 14, and the second air duct 16 connects the air duct 22 and the air inlet end of the fan 3. In this way, when the fan 3 is started, the air inlet baffle 13 can guide the external air to flow from the air inlet 11 to the air duct 22, and the air outlet baffle 14 can guide the air to flow from the air duct 22 to the air outlet 12. The cooperation of the two can limit the air flow direction in the casing 1, ensuring that most of the wind in the casing 1 will pass through the air duct 22, thereby increasing the wind force passing through the air duct 22, thereby increasing the amount of water brought out by the fan 3.

[0038] See also Figure 2 As shown, in one embodiment of the casing 1 and the fan 3, the air inlet 11 is symmetrically opened on both sides of the casing 1, the air inlet baffles 13 are symmetrically distributed on both sides of the casing 1 corresponding to the air inlet 11, and the air outlet 12 is opened at the top of the casing 1. The fan 3 includes a centrifugal wind wheel or an axial flow wind wheel 31, the rotating shaft of the centrifugal wind wheel or the axial flow wind wheel 31 extends in the vertical direction, and the centrifugal wind wheel or the axial flow wind wheel 31 is configured to drive the air in the casing 1 to flow vertically upward. In this way, when the centrifugal wind wheel or the axial flow wind wheel 31 rotates at a high speed, it can suck air in a backward centrifugal manner, drive the air to flow from bottom to top, thereby driving the external air to enter the casing 1 from the air inlets 11 on both sides of the casing 1, and because the wind force of the centrifugal wind wheel or the axial flow wind wheel 31 is relatively large, the amount of water brought out by the fan 3 can be increased.

[0039] The centrifugal wind wheel or axial flow wind wheel 31 may use an impeller of an existing centrifugal fan or axial flow fan, and may be fixedly installed in the casing 1 by means of screw connection or welding.

[0040] See also Figure 2 As shown, in one embodiment of the housing 1 and the fan 3, the housing 1 has a water tank 17, and the water absorbing blades 21 include a water absorbing layer (not shown in the figure), and the water absorbing layer is partially or completely located in the water tank 17. In this way, when the wind passes through the air duct 22, it will contact the water absorbing layer of the water absorbing blades 21, thereby taking away the water on the water absorbing layer, and the water tank 17 can supply water to the water absorbing layer.

[0041] The water-absorbing blade 21 can be made of a water-absorbing material as a whole, or as in the above-mentioned embodiment, a water-absorbing layer can be bonded to the outside of the water-absorbing blade 21, and the water-absorbing layer can be made of a water-absorbing material. In this way, when wind passes through the air duct 22, it will contact the outer side of the water-absorbing blade 21, thereby taking away the water on the water-absorbing blade 21.

[0042] In one embodiment of the water wheel 2, the water wheel 2 is rotatably connected to the housing 1. The wind wheel type humidifier also includes a water wheel driving member (not shown in the figure), which can be fixed to the housing 1 by bolts, and the output end of the water wheel driving member is circumferentially fixedly connected to the water wheel 2 by screw connection or pin connection, and the water wheel driving member is used to drive the water wheel 2 to rotate. In this way, when the water wheel driving member drives the water wheel 2 to rotate, it can drive the water absorption layer on the water absorption blade 21 located outside the water tank 17 to enter the water tank 17 to absorb water and replenish water, and at the same time, it can drive the water absorption layer on the water absorption blade 21 located inside the water tank 17 to move out of the water tank 17, ensuring that when the wind passes through the air duct 22, it can always contact the water absorption layer with sufficient moisture, thereby increasing the amount of water brought out by the fan 3.

[0043] The water wheel driving member can use existing rotation driving mechanisms such as motors and reduction gears.

[0044] See also Figure 3 As shown, Figure 3 2 is an exploded view of the water wheel and the fan in the embodiment. In one embodiment of the water wheel 2, the water wheel 2 further includes a water wheel shaft 23, and each water suction blade 21 is evenly spaced along the axial direction of the water wheel shaft 23, and the interval between two adjacent water suction blades 21 is configured as an air passage 22. In this way, the more even the interval between the water suction blades 21 is, and the greater the number of the water suction blades 21 is, the larger the contact area between the wind and the water wheel 2 is, so that the amount of water brought out by the fan 3 can be further increased.

[0045] See also Figure 3 As shown, in one embodiment of the water wheel 2 , the water wheel 2 further includes two fixed toothed discs 24 , which are respectively screwed to both ends of the water wheel shaft 23 , and the plurality of water-absorbing blades 21 are clamped between the two fixed toothed discs 24 .

[0046] The fixed toothed disc 24 can be meshed with the output end of the water wheel driving member to drive the water suction blades 21 to rotate.

[0047] See also Figure 1 and Figure 2 As shown, in one embodiment of the feeding mechanism 2, a grid portion 18 is integrally connected or clamped at the air outlet 12 of the housing 1. In this way, when the wind wheel humidifier is in use, the grid portion 18 can further disperse the water mist blown out of the fan 3, making the water mist blown out of the humidifier finer and more able to combine with external dust, thereby improving the dust removal and humidification effect of the humidifier.
