Abstract

The invention discloses a bladeless fan. The bladeless fan comprises an air-suction assembly and an air-outlet mask; air-outlet slots are formed in the air-outlet mask; the air-outlet slots are in arc shapes, and an annular outer air-outlet area and an annular inner air-outlet area are formed by the air-outlet slots on the air-outlet mask. The bladeless fan is low in noise and large in air-outlet volume.

Description

A kind of without blade fan
Technical field
The invention belongs to the fan structure design field, be specifically related to a kind of without blade fan.
Background technique
At present commercially available without the blade profile Safety far, comprise base and be arranged on the annular air-out face shield on base, in base, be provided with that to take the turbo type blower fan be main air draught assembly; The great advantage of this fan is due to the traditional electrical fan flabellum used of having forgone, thereby no matter to the adult or the child all has fabulous Security.But this fan also has the following disadvantages: for fear of huge too fat to move, adopt the base of small diameter, so limited the size of turbo type blower fan, in order to guarantee enough air outputs, the rotating speed of turbo type blower fan is higher, generally reach the per second hundreds of to thousands of turning, cause noise very large, and be difficult to eradicate; In addition, because the diameter of turbo type blower fan is too little, although its rotating speed is very high, air output still can not be compared with conventional fan, the blowing poor effect.
Summary of the invention
The purpose of this invention is to provide that a kind of noise is less and air output is larger without blade fan.
The technological scheme that realizes the object of the invention is: a kind of without blade fan, comprise air draught assembly and air-out face shield; Outlet air surface is covered with the air-out slot; The shape of air-out slot is arc shaped, and the air-out slot is arranged in outer wind outlet area and the interior wind outlet area of ring-type on the air-out face shield.
Noise of the present invention is less and air output is larger.
The accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention;
Fig. 2 is a kind of front view without blade fan shown in Figure 1.
Embodiment
(embodiment 1)
The present embodiment is a kind of without blade fan, sees shown in Fig. 1 and Tu, comprises air draught assembly 1 and air-out face shield 2; Outlet air surface is covered with intake opening 21, air-guiding aisle 22 and air-out slot 23; Intake opening is arranged on the center, the back side of air-out face shield, and the air-out slot is arranged on the front of air-out face shield; The air draught assembly comprises housing 11, be arranged on suction fan 12 in housing, be arranged on the air channel 13 in housing; One end of housing is provided with the mesh plate 14 as air inlet of air duct, and the other end of housing is provided with duct outlet 15; Duct outlet is communicated with air-out face shield intake opening; Air-out face shield intake opening place is provided with assembly department 24, and the end that housing is provided with duct outlet is fixed in this assembly department.
Housing is provided with between the inwall of the outer wall of an end of duct outlet and air-out face shield assembly department and is provided with seal ring 4.
Described suction fan is turbofan or the fan with flabellum.What the present embodiment was used is the turbofan with turbine flabellum 121, but it is also feasible selecting conventional fan, and can effectively reduce noise.
The present embodiment also comprises cold 3 of a plurality of electricity; Cold of electricity is arranged in air channel and in abutting connection with the mesh plate place; In concrete practice, also can be arranged on cold of electricity in the air-out face shield and in abutting connection with the duct outlet place.
The basic shape of air-out slot is arc shaped, leaves spacing between each air-out slot.
The air-out slot is arranged in outer wind outlet area 25 and the interior wind outlet area 26 of ring-type on the air-out face shield.
Obviously, the above embodiment of the present invention is only for example of the present invention clearly is described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all mode of executions.And these belong to apparent variation or the change that connotation of the present invention extends out and still belong to protection scope of the present invention.
