The inventor finds that, in the using process of the air conditioner, a user needs to adjust the air outlet direction of the indoor unit sometimes, for example, the air outlet direction is adjusted reversely or at other angles. In addition to air conditioning, some fans also need to effect a change in wind direction.

In order to change the air outlet direction, the inventor thinks that the fan is reversed through the integral rotation of the fan so as to change the air outlet direction of the air conditioning equipment. This implementation, however, faces a number of challenges.

For example, when the fan integrally rotates, the fan can drive the driving motor to rotate together with other internal structures, the power line and the control line, the required torque is large, the torque demand on the driving motor is large, if the design is poor, the fan is not stably turned or even does not rotate, the reversing reliability of the fan is low, and the user experience is influenced.

Moreover, if the rotating mechanism is not properly designed, the lead of the driving motor can be abraded along with the rotation of the fan, even broken and broken, and the reversing reliability of the fan can be influenced. In addition, some electrical equipment receive structural constraint, lead to the fan itself to be difficult to follow and dismantle in the fan frame, and the maintenance is difficult.

Based on the idea of changing the direction of air outlet by reversing the whole fan, the present disclosure provides a fan device, which can be used in an air conditioner indoor unit of an air conditioner and can also be used in air conditioners such as fans.

As shown in fig. 1-11, in some embodiments, includes: a mounting frame 2, at least two fan units 1, a flexible member 3 and a drive unit 5.

The mounting frame 2 serves, among other things, to mount and carry the fan unit 1 and the drive unit 5, while also forming a housing for the fan unit.

Each fan unit 1 is at least partly arranged within the mounting frame 2 and is rotatably arranged relative to the mounting frame 2. The fan unit 1 may be integrally provided in the mounting frame 2, or may have a part of the structure exposed from the mounting frame 2.

The flexible part 3 is arranged in the mounting frame 2 and sleeved outside the driving wheels 12 of the at least two fan parts 1, and the flexible part 3 is contacted with each driving wheel 12 to realize the transmission of driving force. For example, the flexible member 3 may be a V-belt, a circular belt, a combined belt, a chain, or the like, and accordingly, when the flexible member 3 is a transmission belt, the transmission wheel 12 is a pulley; when the flexible member 3 is a driving chain, the driving wheel 12 is a sprocket.

As shown in fig. 7, the driving member 5 is fixed to the mounting frame 2, and the output shaft 51 of the driving member 5 is connected to the transmission wheel 12 to drive the at least two fan units 1 to rotate, thereby changing the orientations of the air inlet I and the air outlet O of the at least two fan units 1. One side of the fan body 11 of the fan component 1, which is located at the air outlet O, is provided with a hemispherical shell 113 to form a tail flow guide body for guiding the flow direction of the air flow.

The fan component 1 connected with the driving component 5 is a driving fan component 1A and can be used as a power source fan assembly, the fan component 1 which is not connected with the driving component 5 is a driven fan component 1B, the driving fan component 1A comprises a first fan main body and a first driving wheel, and the driven fan component 1B comprises a second fan main body and a second driving wheel.

When the fan needs to be reversed, the driving part 5 drives the first driving wheel of the driving fan part 1A to rotate, so that the flexible part 3 is driven to move along the circumferential direction of the driving part, the second driving wheels of the driven fan parts 1B are driven to rotate, and the driving wheels are fixed with the fan main body together, so that the synchronous rotation of the fan parts 1 is realized. The reversing angle of the fan component 1 may be 180 °, that is, the direction of the air inlet I and the air outlet O is switched, or may be other angles larger or smaller than 180 °.

The fan device of the embodiment has at least one of the following advantages:

1. through integrated setting drive wheel 12 on fan body 11 to around each drive wheel 12 outside with flexible component 3, can realize the synchronous rotation of all fan parts 1 when drive part 5 drive part fan part 1 rotates for installation frame 2, improve the synchronism of a plurality of fan part 1 commutations, improve user's comfort level and experience.

2. The number of the driving parts can be reduced, and the driving form of the matching of the driving wheel 12 and the flexible part 3 can transmit larger torque, so that the torque requirement of the fan during reversing can be met, and the fan reversing is more reliable and smooth.

3. When a plurality of fan parts 1 are arranged in the fan device, the transmission mode can easily meet the transmission requirement when the distance of each fan part 1 is far, the requirements on the volume and the arrangement distance of the fan parts 1 can be reduced, and the requirement on the installation precision of each fan part 1 can be reduced.

4. Compared with a gear, the transmission mode has the advantages that the flexible part has certain flexibility, transmission noise can be effectively reduced, transmission is more accurate and stable, the fan can be smoothly reversed, and the stability of the air conditioning equipment in changing the air outlet direction is improved.

5. When the fan device is extruded by external force, the position relation of each fan component 1 can be relatively changed to generate errors, and the flexible component 3 has flexibility, so that the reliability of transmission can be still ensured, the clamping stagnation is prevented, and the reversing reliability of the fan is improved.

In some embodiments, the blower body 11 is a mixed flow blower. Under the same condition, the axial flow fan has small pressure, large air quantity, large noise, large occupied space, large pressure of the centrifugal fan, small air quantity, large occupied space of integral forward and reverse rotation, small pressure of the cross flow fan, large air quantity and large occupied space. Therefore, in order to meet the requirements of air quantity, pressure and size, a mixed flow fan is selected.

Specifically, the mixed-flow fan is small in size and circular in shape, and the size of the fan device is basically not increased by reversing the fan, so that the space size of an indoor unit of the air conditioner is not increased, the size of the fan can be greatly reduced by the high-speed running fan, and the overall size of the unit is further reduced; the mixed flow fan air outlet is circular, compares with traditional centrifugal fan, and the air outlet covers the upper and lower surface of air conditioner heat exchanger basically, and circular air-out is more even, reduces the uneven condition of heat exchanger surface amount of wind distribution by a wide margin to reduce the uneven condition of heat exchanger surface temperature distribution, therefore make user's feeling of wind experience better.

Because the mixed flow fan is used, the surface wind speed of the heat exchanger is more uniform, the surface wind speed of the heat exchanger cannot generate a higher wind speed area under the same wind quantity and the same windward area, and because the surface wind speed of the heat exchanger is improved and the air returning positions of the units are provided with the flow deflectors, the air returning resistance of the units is further reduced; more importantly, the technical scheme is only provided with one fan system, and the other fan system cannot become a resistance source or a new noise source of the unit like the previous scheme; therefore, the noise of the unit can be obviously reduced.

In some embodiments, as shown in fig. 2, the axis of the fan body 11 is arranged along a first direction X, and the fan component 1 is rotatably arranged relative to the mounting frame 2 about a predetermined axis parallel to and passing through the axis of the fan body 11, the second direction Z being perpendicular to the first direction X. The preset axis can be selected in various ways, and in practice, the preset axis can be designed according to the target position of the air inlet I and the air outlet O of the fan body 11. The driving wheels 12 of the at least two fan components 1 are arranged at the same end of the fan body 11 along the second direction Z, and the axes of the driving wheels 12 are consistent with the second direction Z.

As shown in fig. 1 and 2, at least two fan units 1 are arranged at intervals along a third direction Y, which is perpendicular to a plane in which the first direction X and the second direction Z are located, and arranged in a straight line.

Moreover, the flexible component 3 is positioned in the horizontal plane, and because the gravity action of the flexible component is consistent everywhere, the stress of the flexible component is even everywhere in the horizontal plane, so that the reversing of the fan device is more stable, and the flexible component 3 can be supported by the edge of the driving wheel 12 and is not easy to fall off.

In some embodiments, only one of the drive members 5 is provided and is connected to one of the drive wheels 12.
