Abstract

All-round fan, comprising:
a fan body (10) having a stator (11), a motor (12), rotor blades (13) and a housing (14), the housing (14) shielding the rotor blades (13) and an upper housing half (141) has, which is provided centrally with a connecting portion (142); and
a bypass body (20), which is conical and mounted upside down on the connecting portion (142) in the middle of the upper half of the housing (141), and wherein the bypass body (20) has a circumferential arcuate wall (21) extending from the center the upper housing half (141) is bent upwards and outwards, whereby the flow of the fan under the guidance of the arcuate wall (21) in all directions of the environment of the Umströmungskörpers (20) can be promoted.

Description

The invention relates to a fan, in particular an all-round fan which simultaneously blows in all directions (360 degrees).

In conventional fans with a rotatable head, the head can only be rotated back and forth to a limited extent within a certain range. If people sit very far away from each other, only those who are sitting in the air area can feel the flow of air. That is in need of improvement.

Recently, a fan with a double head has come on the market, which can blow wind in two different directions. However, it is not recommended to turn this fan to prevent the occurrence of gusts. In addition, this fan can only be placed in the wall corner, which is not manageable. Commercially available there are still 360-degree rotatable fans, but characterized by complicated structure and high production costs. Such fans are not popular because of the high cost and are difficult to repair. For these reasons, 360-degree rotatable fans still have potential for improvement.

The invention is therefore an object of the invention to provide an all-round fan, which can simultaneously blow in all directions (360 degrees) wind, wherein the blown from the fan airflow is discharged in all directions to ensure that the fan at the same time Wind blows in all directions.

This object is achieved by a fan all around blowing, which has the features specified in claim 1. Further advantageous developments of the invention will become apparent from the dependent claims.

According to the invention there is provided an all-round fan having:
a fan body having a stator, a motor, rotor blades, and a housing, the housing shielding the rotor blades and having an upper casing half centrally provided with a connecting portion; and
a bypass body, which is conical and is mounted upside down on the connecting portion in the middle of the upper half of the housing, and wherein the Umströmungskörper having a circumferential arcuate wall, which is bent from the center of the upper half of the housing upwardly and outwardly.

In the following the invention and its embodiments will be explained in more detail with reference to the drawing. In the drawing shows:

1 a schematic representation of an embodiment of an all-round fan blower according to the invention;

2 an exploded perspective view of the embodiment of an all-blasting fan according to the invention;

3 a schematic representation of the air flow of the embodiment of an all-blasting fan according to the invention; and

4 a perspective view of a Umströmungskörpers according to another embodiment of an all-blasting fan according to the invention.

Referring to 1 and 2 an inventive, all-round fan blowing a fan body 10 and a flow body 20 on. The fan body 10 consists of a stand 11 a motor 12 , Rotor blades 13 and a housing 14 , The motor 12 is on the stand 11 attached by the axle center 121 of the motor 12 is directed vertically upwards. The rotor blades 13 are horizontal at the axle center 121 grown. The housing 14 shields the rotor blades 13 from top to bottom. The flow body 20 is conical and with screws 30 in the middle of the upper half of the housing 141 arranged connecting portion 142 attached. The flow body 20 is in terms of area at least as large as the flow area of the fan. The flow body 20 has a circumferential arcuate wall 21 on top of that from the top half of the case 141 starting bent upwards and outwards.

As in 3 is shown by the rotor blades 13 generated air stream after assembly of the above-mentioned components for use upwards, since the engine 12 is arranged vertically upwards. Under the guidance of the arched wall 21 of the flow body 20 the air flow in all directions of the environment of Umströmungskörpers 20 All people around the fan, regardless of where they stand, feel the flow of air. In this way it can be ensured that the fan according to the invention can simultaneously blow wind in all directions.

In 4 a further embodiment of the Umströmungskörpers invention is shown, evenly with a plurality of projecting ribs 22 is provided. Between every two ribs 22 is a guide groove 23 formed, through which the currents are derived. As a result, the flow direction can be stabilized. On the flow body 20 can a cover ring 24 provided or the Umströmungskörper 20 can be aesthetically designed to provide an aesthetic appearance.

As explained above, the fan according to the invention is easy to produce. Without a complicated swivel head, the fan can simultaneously blow wind in all directions, increasing its practicality.
