It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "plurality" or "a plurality" means two or more unless specifically defined otherwise.

Referring to fig. 1 to fig. 3, a description will now be given of a dehumidifying structure of a new fan according to an embodiment of the present invention. A new fan dehumidification structure, comprising:

the plurality of baffle plates 2 are stacked, a bent circulation gap 21 is formed between every two adjacent baffle plates 2, and the baffle plates are suitable for being installed in a main air duct 1 of a fresh air fan; and

and the adjusting mechanism is connected with at least one of the two adjacent baffles 2 and is used for driving the two adjacent baffles 2 to move close to or away from each other so as to change the width of the flow gap 21 between the two adjacent baffles 2.

Compared with the prior art, according to the dehumidification structure of the fresh air machine, air with high humidity in the main air channel 1 of the fresh air machine flows through the bent circulation gap 21 between the two adjacent baffle plates 2, and fine water drops in the air are adsorbed on the baffle plates 2, so that the air humidity is reduced, electric energy does not need to be consumed, the energy consumption of a fresh air system is reduced, the dehumidification amount is high, and the dehumidification requirement can be met; can also change the width in circulation clearance 21 through adjustment mechanism, adjust the dehumidification effect, the scope that this kind of structure dehumidification volume was adjusted is narrower, but can satisfy the dehumidification requirement of new trend system, simple structure, convenient operation moreover.

Of course, in specific implementation, the usage scenario of the new fan dehumidification structure is not limited to the new fan which adopts the wet curtain to purify air, which is proposed by the inventor, and is only exemplified here.

In this embodiment, the new fan dehumidification structure is installed in the main air duct 1 of the new fan when in use, so that the humid air in the main air duct 1 flows through the curved circulation gap 21 of the new fan dehumidification structure. The plurality of baffles 2 are stacked, and adjacent baffles 2 are spaced apart from each other by a predetermined distance to form a curved flow gap 21. The baffle 2 may be bent in a zigzag shape or in an arc shape to form a zigzag-bent or arc-bent flow gap 21.

The adjusting mechanism can be connected with one of the two adjacent baffle plates 2 to adjust the distance between the two adjacent baffle plates 2; the adjusting mechanism can also be simultaneously connected with two adjacent baffle plates 2 respectively to adjust the distance between the two adjacent baffle plates 2. The adjusting mechanism changes the width of the circulation gap 21 by adjusting the distance between two adjacent baffle plates 2, and adjusts the dehumidification effect.

When the width of the circulation gap 21 is close to zero, the flow resistance is large, the flowing wet air is less, the contact between the wet air and the baffle plate 2 is less, and the dehumidification amount is minimum; when the circulation gap 21 is gradually widened, the flow resistance is reduced, the flowing wet air is increased, the contact between the wet air and the baffle plate 2 is increased, the dehumidification amount is gradually increased until the dehumidification amount reaches the maximum, and the width of the circulation gap 21 is different when the dehumidification amount reaches the maximum due to different air flow rates, sizes of the circulation gap 21 and the like; thereafter, when the flow gap 21 becomes wider, the flow gap 21 becomes too open, and the contact of the humid air with the baffle plate 2 is reduced, resulting in a decrease in the amount of dehumidification.

In the use process, the adjusting mechanism controls the middle baffle plate 2 to move left until the middle baffle plate 2 is attached to the left baffle plate 2, so that the flow gap 21 between the middle baffle plate 2 and the left baffle plate 2 is narrowest, the flow gap 21 between the right baffle plate 2 is widest, and the humid air mainly flows through the right flow gap 21 and rarely flows through the left flow gap 21. At this time, the flow gap 21 on the left side has less humid air flowing therethrough, and the contact between the humid air and the baffle plate 2 is small, so that the dehumidification amount is minimum; the right-hand circulation gap 21 is too unobstructed and there is less contact of the humid air with the baffle 2, resulting in a dehumidification not reaching the maximum dehumidification either; thus, the moisture removal amount is small as a whole.

When the adjusting mechanism controls the middle baffle plate 2 to start moving rightward, the flow gap 21 between the middle baffle plate 2 and the left baffle plate 2 gradually becomes wider, and the flow gap 21 between the right baffle plate 2 gradually becomes narrower. In this process, the wet air flowing through the left circulation gap 21 increases, the contact between the wet air and the baffle plate 2 increases, and the dehumidification amount gradually increases; the flow resistance of the right circulation gap 21 gradually increases, the contact between the humid air and the baffle plate 2 increases, and the dehumidification amount also gradually increases, so that the total dehumidification amount becomes large. When the whole dehumidification amount reaches the maximum, the adjusting mechanism controls the middle baffle plate 2 to continuously move rightwards, and the dehumidification amount starts to descend again until the middle baffle plate 2 is attached to the right baffle plate 2, so that the detailed description is omitted.

Referring to fig. 1 to 3, as an embodiment of the new fan dehumidifying structure provided by the present invention, the adjusting mechanism includes a cross bar 3 traversing a plurality of baffle plates 2; in two adjacent baffle plates 2, one baffle plate 2 is fixed with a cross rod 3, and the other baffle plate 2 is provided with a sliding hole to enable the cross rod 3 to slide through.
