to achieve these goals, the technical solution of the utility model is: a kind of without blade fan, comprising:
Housing, this housing limits inner passage, and this inner passage has at least one suction port and at least one air outlet;
Cross flow fan, is arranged in described inner passage, and is placed in the downstream of described suction port, and the vane rotary of described cross flow fan enters described inner passage with suction airstream through described suction port, and at least a portion of described air-flow goes out from the transmitting of described air outlet.
the design philosophy of this technological scheme is: adopt cross flow fan, as the air-flow without blade fan, source occurs, without turbulent flow, air-out is even, and air quantity is large, and noise is low, and air flow energy arrives far distance.
As preferably, ringwise, the center of this toroidal shell has through hole to described housing, and described suction port and air outlet lay respectively on two opposing sides that through hole passes, and the air-flow suction of being launched from air outlet from the secondary streams of fan outside is by described through hole.Housing can be annulus, elliptical ring, apple shape or polygonal etc.
As preferably, described cross flow fan has a plurality of, and it is circumferentially uniform in through hole.
As preferably, described cross flow fan has two, it is relatively arranged at the axle core both sides of through hole, described cross flow fan has default rotating speed upper and lower bound when operation, when the rotating speed of a cross flow fan is wherein during from the upper limit to lower limit variation, the rotating speed of another cross flow fan changes to the upper limit from lower limit.When two cross flow fan rotating speeds change relatively, that gives people feels to have produced the effect of pendulum wind of shaking the head.
as preferably, described housing comprises interconnected fore shell and back cover, the cavity that forward and backward hull shape becomes is described inner passage, the two ends of described through hole lay respectively at the center of fore shell and back cover, described suction port is positioned on back cover, described air outlet is positioned on fore shell, and the area of described suction port is greater than the area of air outlet.Forward and backward shell is spliced to form housing, convenient mounting or dismounting, facilitate provided with fan assembly within it simultaneously, housing is divided into two of front and back, be convenient in front and back, offer intake grill and exhaust outlet, and can not affect air-out effect, the area of suction port is greater than the area of air outlet, can reach air-flow multiplication effect, the air-flow wind speed of ejaculation is larger.
as preferably, described suction port consists of a plurality of circular holes uniform at least one region limiting on back cover, and described air outlet consists of a plurality of bar holes uniform at least one region limiting on fore shell.The suction port air inlet of circular hole is more smooth and easy, and the air outlet of bar hole is given vent to anger more even, and flow velocity is larger.Certainly, bar hole shape also all can be made in suction port and air outlet.
As preferably, in described housing, be provided with filter, the downstream of this filter in suction port, between suction port and cross flow fan.Filter is used for filtering the impurity such as dust, purifies air, and can extend the working life of blower fan, reduces noise.
As preferably, in described housing, be provided with heating equipment, the upstream of this heating equipment in air outlet, between air outlet and cross flow fan.Heating equipment, for heating air flow, has been realized the function of the exportable warm braw of fan.
As preferably, on described fore shell, LED display is housed.This LED display can provide the Presentation Functions such as time, temperature.
As preferably, the rotating speed of described cross flow fan is at least 500rpm.More than remaining on 500rpm, stable blow out air stream, guarantees Energy Efficiency Ratio.
the utility model without the beneficial effect of blade fan is: this adopts cross flow fan, as air-flow, source occurs without blade fan, and without turbulent flow, air-out is even, and air quantity is large, and noise is low, and air flow energy arrives far distance.
