Abstract
The invention discloses a bladeless fan comprising a base, a substrate and a nozzle. A fan is disposed in the substrate. The nozzle is of a flat and elongated shape narrowing gradually from top to bottom. Air inlet holes are formed in the shell of the substrate and in an area under the fan and above the base. By the bladeless fan, vibration brought by air flow in the air inlet holes is alleviated, and low-frequency noise is reduced; inlet air at the entrance to the fan can be balanced, vibration of a fan body caused by the uneven inlet air of the fan can be avoided, and fan noise can be reduced.
Description
Technical field
The present invention relates to a kind of fan, refer to especially a kind of without blade fan.
Background technique
Thereby traditional fan all is to produce wind by the motor drives blade rotary, accelerate the flowing velocity of the air draught of surrounding environment, thereby reach the effect of cooling and heatstroke-eliminating and ventilating air, (when taking advantage of the adult and do not note such as: the child who has finger is stretched in the electric fan but that this traditional fan is easy to produce is dangerous, just injured by blade), there is certain potential safety hazard, and is inconvenient to clean.
Summary of the invention
In view of this, the object of the invention is to propose a kind of without blade fan, by intake opening is designed, to reduce windage and the noise without the blade fan intake opening, reduce fan vibration.
Provided by the invention a kind of without blade fan based on above-mentioned purpose, comprising:
Base, pedestal and nozzle, described base interior is provided with blower fan, and described nozzle is flat elongated shape, dwindles gradually from bottom to top, at the shell of described pedestal intake opening is set, and described intake opening is positioned at the zone that blower fan is following, base is above.
Further, the blower fan of described base interior is arranged on 2/5 above part of pedestal.
Optionally, described pedestal is spherical, the radius SR of spheroid be 30mm between the 300mm, arrange intake opening at the lower semisphere shell of spherical base.
Further, described intake opening is from 4000 to 7000.
Optionally, described intake opening is 4000 to 4500, or 4600 to 4900, or 5000 to 7000.
Further, the perforate gross area is from 4000mm
2To 4100mm
2
Further, the centre distance between the described intake opening is from 2mm to 5mm.
Further, described hole be shaped as circle, the diameter of each intake opening is from 0.7mm to 2mm.
Optionally, the diameter of each intake opening be 0.7mm to 0.8mm, or 0.85mm is to 1.2mm, or 1.5mm is to 2mm.
Further, the region height of described intake opening is from 18mm to 65mm.
Further, the extreme higher position of described intake opening should be no less than 5mm apart from the blower fan lower surface.
Further, the between the upper and lower distance between the intake opening is that 2.4mm is between the 2.8mm.
Optionally, between the described intake opening between the upper and lower apart from arriving 2.5mm or 2.6mm for 2.4mm between the 2.8mm.
Further, the air intake flow velocity of described intake opening is from 3m/s to 10m/s.
Can find out from above, provided by the invention a kind of without blade fan, not only customer service the potential safety hazard of conventional fan, and the design of nozzle and pedestal is unique, modern design is attractive in appearance.By the design of intake opening, not only greatly reduced flow velocity and the windage at fans entrance place, and reduced the vibration that the intake opening place causes because of gas flow, thereby reduced the vibration that the intake opening place causes because of gas flow, and then reduced low frequency noise; Can balance fans entrance air intake, the body vibration of avoiding blower fan to cause because air intake is inhomogeneous reduces fan noise.

For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with specific embodiment, and with reference to accompanying drawing, the present invention is described in more detail.
Fig. 1 is the structural representation without blade fan of the embodiment of the invention.Comprise base 1, pedestal 2 and nozzle 3 without blade fan, nozzle 3 is flat elongated shape, dwindles gradually from bottom to top, at the shell of pedestal 2 intake opening 4 is set, and its intake opening 4 is positioned at that blower fan is following, the zone of base more than 1.Wherein, pedestal 2 inside are provided with blower fan, and blower fan is arranged on pedestal 2 inner top positions as far as possible.Optionally, the blower fan of pedestal 2 inside is arranged on 2/5 above part of pedestal 2.
Further, pedestal 2 can be elected sphere as, and intake opening 4 is opened on spherical base lower semisphere outer surface.
Further, the air intake flow velocity of intake opening 4 is from 3m/s to 10m/s, reduces vibration and fluid noise that blower fan causes because air intake is inhomogeneous.
Fig. 2 be the embodiment of the invention 1 without the local stereogram that splits of blade fan.Wherein pedestal 2 has comprised that also flow blower casing 21 and position are used for sucking from intake opening 4 blower fan of outer gas stream and generation internal gas flow upwards in the inner, be arranged on the blower fan and the wind scooper 22 that links to each other with flow blower casing 21, it is used for upwards guiding the internal gas flow of blower fan generation, and described blower fan is positioned at the top of described intake opening 4.
The opening area schematic representation of Fig. 3 intake opening of the present invention.As shown in Figure 3, take to arrange at the lower semisphere outer surface structure of aperture without the intake opening of blade fan, the size of perforate, spacing and the gross area have considered the problem of noise reduction and windage.For instance, when pedestal was elected sphere as, between the 300mm, preferred SR was 120mm to the radius SR of spheroid at 30mm, and the lower surface of blower fan is arranged intake opening in the equatorial position of spheroid in the zone more than the base, below the blower fan.Concrete, below 18mm is to the annular region uniform perforate all around of (being the perforate height) between the 65mm under the line.Preferably, the extreme higher position of intake opening should be no less than 5mm apart from the blower fan lower surface.Perforate adds up to 4000 to 7000, alternatively, and 4000 to 4500, or 4700 to 4900, or 5000 to 7000, be preferably 4700 to 4900.The perforate gross area is from 4000mm
