Description

Technical Field

[0001] This utility model relates to the field of wind turbine technology, and more specifically, to a wind turbine structure for a heater. Background Technology

[0002] Most bathroom heaters use a motor to drive a fan to circulate and transport air. Some heaters, to simplify their internal structure, use a single fan to achieve both blowing and ventilation; the fan rotates forward when blowing air and reverses when ventilating.

[0003] However, most current impeller structures, such as the air guide wheel structure of a vacuum cleaner disclosed in utility model patent with publication number CN202421597991.1, have simple arc-shaped blades. When rotating forward, the air volume is large, but when rotating in reverse, the air volume is small.

[0004] Therefore, there is an urgent need for a wind turbine structure with large air volume in both forward and reverse rotation. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model provides a fan structure for a heater to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fan structure for a heater, comprising a hub, a top ring, and several blade units, wherein the several blade units are fixedly fixed to the hub at equal intervals along the circumference of the hub, the top ring is fixedly connected to the top of the several blade units, and the blade unit includes a first blade and a second blade, the first blade being located near the center of the hub, and the second blade being located near the edge of the hub, the first blade and the second blade having opposite inclination angles, the first blade being inclined in a clockwise direction toward the hub, and the second blade being inclined in a counterclockwise direction toward the hub.

[0007] By adopting the above technical solution, the first blade is tilted clockwise and the second blade is tilted counterclockwise. When the impeller structure rotates clockwise, it sends air out through several first blades, increasing the air volume. When the impeller structure rotates counterclockwise, it sends air out through several second blades, increasing the air volume. This allows the impeller structure to provide a large air volume whether it rotates clockwise or counterclockwise, effectively solving the problem of low ventilation volume in single-impeller heaters.

[0008] The present invention is further configured such that the first blade is preferably an arc-shaped plate, specifically in the shape of "(", the angle between the two ends of the first blade and the center of the hub is 3-5°, and the opening direction of the first blade is clockwise.

[0009] The present invention is further configured such that the second blade is a flat plate and the angle between the two ends of the second blade and the center of the hub is 1-2°.

[0010] Compared with the prior art, the present invention provides a fan structure for a heater, which has the following beneficial effects: The first blade is tilted clockwise, and the second blade is tilted counterclockwise. When the wind turbine rotates clockwise, it sends air out through several first blades, increasing the air volume; when the wind turbine rotates counterclockwise, it sends air out through several second blades, increasing the air volume.

[0011] This design ensures that the impeller structure can provide a large air volume whether it rotates forward or backward, effectively solving the problem of low ventilation volume in single-impeller heaters. Attached Figure Description

[0019] The blade unit 3 includes a first blade 301 and a second blade 302. The first blade 301 is located near the center of the hub 1, and the second blade 302 is located near the edge of the hub 1. The first blade 301 and the second blade 302 have opposite tilt angles. The tilt direction of the first blade 301 is clockwise towards the hub 1, and the tilt direction of the second blade 302 is counterclockwise towards the hub 1.

[0020] Specifically, the first blade 301 and the second blade 302 are connected end to end and formed as a single piece.

[0021] like Figure 2 As shown, the first blade 301 is preferably an arc-shaped plate.

[0022] Specifically, the cross-section of the first blade 301 is "", the angle between the two ends of the first blade 301 and the center of the hub 1 is 3-5°, and the arc-shaped opening of the first blade 301 faces clockwise.
