[0004] If the motor can be turned to work horizontally, [such as patent application number 201110256873.5], the wind blown from the horizontal inner impeller needs to turn 90° once more to reach the closed annular nozzle, so the wind force will be more obviously weakened. The above structure No matter the power loss, noise and cost of the bladeless fan are large, the application range is not wide, so it is necessary to improve

[0026] Depend on Figure 1-2 Shown is the first embodiment of the present invention: it includes a small annular fixed ring 2 set on the motor 1, an inner leaf 3 is installed, a cover body 4 with a row of holes and a small Coanda ring cover 5 are covered; The cover body 4 is provided with three air supply pipes 6 on three symmetrical sides of the inner leaf 3 , and the tops of the three air supply pipes 6 are extended and connected to form an annular air outlet 8 , which is connected with a large attached wall ring 9 . Use the described motor cover 4 with exhaust holes to take in the air.
[0027] There is a thickened pipe wall connected with the small annular fixed ring 2 in the described air supply pipe 6, so that the air supply pipe becomes the hollow fixed support frame 7 of the working motor at the same time. The hollow fixed support frame 7 is connected with the large wall attachment ring 9 so that the large wall attachment ring becomes a solid large fixed ring frame 10...

The invention discloses an inner-impeller fan with multipurpose blast pipes. The inner-impeller fan is characterized by comprising a motor (1), a small annular fixing ring (2), an inner impeller (3), a cover body (4) with an air inlet gap and a small wall-attached ring cover (5), wherein the motor is tightly sleeved with the small annular fixing ring (2), the inner impeller (3) is arranged, and then the cover (4) with the air inlet gap is installed. The bottoms of the blast pipes (6) are connected with the small annular fixing ring (2), the tops of the blast pipes (6) are extended to be connected to form an annular air outlet (8) to be connected to a large wall-attached ring (9), the blast pipes (6) serve as a hollow fixing and supporting frame (7) of the motor (1) at the same time, and meanwhile the large wall-attached ring (9) serves as a large fixing ring frame (10). Airflow generated by the inner impeller (3) passes through the blast pipes (6) to be guided to the annular air outlet (8), and even and low-noise air is blown out along the two walls where the large wall-attached ring (9) and the small wall-attached ring cover (5) are attached. The inlet air, the blasted air and the outlet air are coincident in direction, the blast pipes, the large wall-attached ring and the small wall-attached ring respectively have two purposes, the motor is fixed in an annular ring frame to transversely work, the structure is compact, and materials are saved. The blast pipes are manufactured to be in transparent fan impeller shapes and internally provided with light sources which emit light in turn, persons will feel that the fan impeller rotates, and the advantages of an impeller-free fan and the advantages of a traditional fan are mostly combined.
Description
technical field [0001] The patent of the present invention belongs to the field of fan technology, and in particular relates to an inner blade fan device. Background technique [0002] Because the impeller is not exposed, the bladeless fan has the advantages of good safety and easy cleaning, so it is favored by people [such as the fan disclosed in Patent Application No. 200810177844.8]. [0003] But the existing bladeless fan motor works upright under the annular closed circle, and the wind generated by the inner impeller blows upwards. It needs to turn more than 50° to reach the annular closed nozzle circle, and then needs to turn 180° to blow out from the annular nozzle. , the use of Coanda surface also requires a turn of more than 120°, and the wind force will be significantly weakened. [0004] If the motor can be turned to work horizontally, [such as patent application number 201110256873.5], the wind blown from the horizontal inner impeller needs to turn 90° once more...
