Description

Two electricity consumption circulation fan of natural wind/warm wind
Technical field
The present invention relates to the pumping installations that working fluid is air, more particularly to be provided with heat emitting medium and air with The air conditioning fan that the heat emitting medium directly contacts, more particularly to possess larger incoming air area, to increasing nature wind The two electricity consumption circulation fan of natural wind/warm wind of output.
Background technique
Prior art circulation fan is referring to fig. 4 a kind of electric circulation fan for blowing natural wind, dress axial-flow leaf, in the wind Radially site boundary to the front is provided with annular passage to leaf or a part of cylindrical shell is used as air duct.Wind when operation Leaf rear is radial and axial all to enter the wind from the body shell of grid or mesh, guarantees enough air quantity, and due to air duct Restrictive function is, it can be achieved that farther away air supplying distance.
The prior art is as well as a kind of warm-air drier, is to blow the electric circulation fan of heating air stream, and fill referring to Fig. 5 With axial-flow leaf, heat generating component is set in the fan blade axial rearward direction, while being also arranged in the fan blade and heat generating component radial periphery A part of air duct or fuselage cylindrical housings is used as air duct, i.e. fan blade and air duct is all wrapped in same body shell It is interior.When operation, natural air corresponds to grid or the mesh sucking of air duct axial rearward from fuselage rear, guarantees supply fever Component has enough air quantity to radiate, but the indexs such as its air quantity and air supplying distance, is but all far below the nature of equivalent diameter fan blade Wind-powered electricity generation circulation fan, thus be not suitable for using as common natural wind-powered electricity generation circulation fan.
Summary of the invention
The technical problem to be solved in the present invention is that providing a kind of nature in place of avoiding above-mentioned the deficiencies in the prior art Two electricity consumption circulation fan of wind/warm wind can select a circulation fan for being used as blowout natural wind, or be used as blowing the heating of hot wind Machine.Guarantee enough air quantity and air supplying distance when using as the circulation fan for blowing natural wind, and as warm-air drier in use, then Still ensure that satisfied heat dissipation effect.
The present invention solve the technical problem the technical solution adopted is that, a kind of two electricity consumption circulation fan of natural wind/warm wind, packet Include body shell and support the body shell base assembly, and be mounted on the body shell forefront grid or it is netted before Cover;
It forward coaxially successively include: motor, air guide ring, heating unit assembly and fan blade after in the body shell;
Body shell front is air duct, is a part of the body shell, is also possible to an independent component, is assembled fixation In the body shell front;The rear portion of the body shell, including bottom surface and the peritropous envelope surface of central axes method be all grid or The air inlet structure of mesh;
Motor is packed in the rearmost inside body shell, and fan blade is axial flow fan leaf, and the axis for being packed in the motor is stretched, and sends out Hot body component is arranged between motor and fan blade, and the radial periphery of heating unit assembly is arranged in air guide ring.
The base assembly is applied not only to support the body shell, can also adjust the body shell outlet air at any time It bows/the elevation angle, but also is the control motor running, shows its operating status and the place position of oscillating head mechanism is installed.Institute Stating air guide ring is hollow truncated conical shell, and bore is pre-small post-large, is seen along center axis thereof toward air-out direction, and ring wall is in gathering Trend has certain taper.The angular range that oblique line on the air guide ring ring wall intersects with center axis thereof is 10 °≤β≤80 ° 。
The heating unit assembly includes bearing support and the metal heating wire that is wrapped in insulation framework, the heating unit assembly It is coaxially packed in air guide ring by its bearing support, the axis of motor stretches the central part for passing through the insulation framework.
When electricity circulation fan operation of the present invention, referring to Fig. 6, fan blade rear is radial and axial to be passed through on body shell Grid or mesh air inlet, wherein having to flow through the metal of heating unit assembly under the restrictive function of air guide ring from axial air inlet Heating wire surface, it is described to be forced to be heated as warming up from axial air inlet if being run under warm-air drier operating condition Wind is seen off.
Compared with the existing technology compared with no matter the beneficial effects of the present invention are be used as nature when the electricity circulation fan is run Wind-powered electricity generation circulation fan, or it is used as warm-air drier, fan blade rear is radial and axial to enter the wind from the body shell of grid or mesh, Guarantee enough air quantity.And due to air duct restrictive function, it can be achieved that farther away air supplying distance.The electricity circulation fan, natural wind, Warm wind selects a selection, and the air output and air supplying distance of prior art nature wind-powered electricity generation circulation fan are all reached under two kinds of operating conditions, is mentioned significantly High equipment service efficiency avoids purchase natural wind and each equipment of warm wind and occupies larger space.
