Description
Technical field
The utility model belongs to the blower fan technical field, especially relates to single motor bilobed wheel blower fan, and this blower fan has two pairs of intake grill and exhaust outlets of mutually isolating, and two intake grills of these two pairs of intake grills and exhaust outlet and two exhaust outlets can be in the same way or oppositely.
Background technique
Traditional blower fan mostly is unidirectional outlet and inlet, and during work, wind constantly enters from the front or the back of blower fan, again from its back or the front flow out.
At present, in the direction about the change inlets and putlets of ventilation, it is more flexible to make it arrangement, satisfies diversified demand side, has also made some improvement.For example, application number is 91106574.1, and the patent application that name is called " ball-type omnidirectional electrical fan " discloses a kind of ball-type omnidirectional electrical fan.It is by base, motor frame, bearing, motor, fan blade, motor cover, guard and control circuit constitute up and down.Motor has 3, is distributed on the same horizontal plane, and each self-driven fan blade, spherical electric fan that can three direction air-out, it can make the almost all people who is positioned at room 360 degree scopes all blow to cool breeze.But it comes down to form three fans with each self-driven impeller of three motors, 120 degree that again center line of three fans intersected each other, uniform being installed in the 360 degree scopes.Therefore, it is actually the combination of three fans.Its cost of production, production technology etc. all improve a lot.
Application number is 93214378, the name be called " but two air intake break-in low noise centrifugal blower " but Chinese patent a kind of pair of air intake break-in low noise centrifugal blower disclosed, be characterized in being provided with radially intake grill and air inlet through hollow shaft mouth, can select different intake grills as required for use.Motor power imports impeller shaft into by the centre of bilobed wheel.This device can change the air intake direction easily, with the requirement that conforms.But it is to have installed transmission device additional between motor and two impellers, so its cost of production also improves a lot.
Application number is 90216385, and the model utility that name is called " the spherical electric fan of double leaf " discloses the spherical electric fan of a kind of double leaf, and its main technical schemes is respectively to adorn one group of fan blade at shaft extension place, motor shaft two ends, can two-wayly blow.Under the drive of head-shaking motor, blade motor is rotation continuously in the horizontal direction simultaneously, can 360 degree air-supplies.Guard and two semicircle spheries are fixed on the guard frame with fastening button, form a whole spheroidal.It does not have the air intake and the air-supply passage of clear and definite mutual isolation, therefore, does not possess the function that the air of a certain specific environment is sent into and sent.
Yet, in some cases, a kind of mutual isolation that has need be provided, have two pairs of independently inlets and putlets of ventilation list motor bilobed wheel blower fans, this independently passes in and out air channel air intake or opposing air-out relatively, thereby can need provide convenience for the special pearl of relative assembly or equipment, obtain beyond thought effect.
Summary of the invention
The purpose of this utility model, just be to overcome the shortcoming and defect of above-mentioned prior art, a kind of mutual isolation of having is provided, have two pairs of independently single motor bilobed wheel blower fans of inlets and putlets of ventilation, can change the opposite direction of inlets and putlets of ventilation, for relative assembly or equipment provide two-way to change functions such as wind or two-way cooling, because of adopting single motor bilobed wheel blower fan, so can reduce volume, relatively low cost of production is arranged, and get and obtain good result.
In order to achieve the above object, single motor bilobed wheel blower fan of the present utility model comprises motor, be connected in the Blower Housing on the shell of the Blower Housing motor on the shell of motor, the axle that is installed in motor is gone up and is arranged in the impeller of Blower Housing and is installed in intake grill and exhaust outlet on the Blower Housing, it is characterized in that having isolating plate in the middle of the described Blower Housing, make it mutual isolation, become two Blower Housings of isolating mutually, each all has independently intake grill and exhaust outlet the Blower Housing that should isolate mutually, impeller on the coaxial axle that is installed in motor also has two, and two impellers lay respectively in two Blower Housings of isolating mutually.
During work, because two impellers install, are fixed on the same motor shaft, thus reduced cost of production, and air intake or air-out relatively in opposite directions
Said motor is positioned at the centre of two Blower Housings and two impellers, and isolating plate is fixed on the shell of motor, and the axle of motor stretches out from the motor both sides, drives two impellers that are positioned at the isolating plate both sides respectively.This structure avoids air-flow to interfere with each other.Motor is positioned at the centre of two Blower Housings and two impellers, and this is a kind of than symmetrical structure, and it is more stable to work, and parts are stressed also more even.
Said motor can also be positioned at a side of isolating plate, and isolating plate is fixed on two Blower Housings, and the axle of motor reaches the opposite side of isolating plate, drives two impellers that are positioned at the isolating plate both sides respectively.This is a kind of dissymmetrical structure, is used to satisfy special pearl needs in some cases.
Single motor bilobed wheel blower fan of the present utility model, its feature are that also the direction of the direction of said two intake grills and two exhaust outlets is in same direction.
The direction of said two intake grills also can with the direction of two exhaust outlets in the opposite direction.
Said two exhaust outlets are positioned at the avris of Blower Housing, two outsides that said two intake grills are positioned on the center line of motor, Blower Housing is relative.
The utility model provides a kind of air intake relatively or air-out in opposite directions, for relative assembly or equipment provide two-way to change functions such as wind or opposing cooling, reduces its volume, reduces production costs, and obtains single motor bilobed wheel blower fan of beyond thought effect.It can be widely used in the equipment of air conditioner, large-sized wind cooling transformer and other need wind-cooling heat dissipating.
