Detailed description of the invention
Below in conjunction with accompanying drawing of the present utility model, the technical scheme of this utility model embodiment is carried out
Clear, complete description.
As it is shown in figure 1, the chiller of a kind of brushless motor of dust collector, including movable vane wheel fan housing 1,
Movable vane is taken turns 2, is determined impeller 3, motor stator 4, rotor 5, is located at rotor 5 and motor is fixed
Motor case 6 outside son 4, and it is arranged at the motor fan housing 7 outside motor case 6, described
One end of motor case is formed with shell end cover 8, is provided with between described motor fan housing 7 and motor case 6
Gap 9.
Motor fan housing 7 is sheathed on outside motor case 6, has both ends and connects the side week at both ends
Portion, wherein one end is arranged at the outside of electric motor end cap, and the end face of this end is provided with air vent 10, cold
But gas can drive plate 11 by vent 10 flow direction motor, and motor drives power on plate 11 open
Close and electric capacity cools down.Also vent 72, vent it is provided with in the side perimembranous of motor fan housing 7
72 are downwardly extending from the end of motor fan housing 7 is alternate, and it is shaped as rectangle or other shapes,
It is flexible that the position of vent 72 arranges comparison.The vent 72 of motor fan housing 7 side perimembranous with determine impeller
3, movable vane wheel fan housing 1 forms gas channel, is conducive to cooling down the flowing of gas, takes away motor heat,
Reduce motor temperature.
More preferably, motor fan housing 7 fixes the outside dimension of the end being connected less than motor with electric motor end cap
Fan housing 7 outside dimension so that form gas channel, beneficially gas flow between end and side perimembranous
Motor drives plate 11, drives plate 11 to cool in motor.
Motor drives plate 11 to be located at outside motor fan housing 7 end, and motor drives the outside dimension of plate 11
Less than the outside dimension of motor fan housing 7, motor fan housing 7 side perimembranous is axially extending, makes motor drive plate
11 are embedded in motor fan housing 7, and and motor fan housing 7 side perimembranous between produce gap, simultaneously at electricity
Machine drives plate 11 to be provided with multiple vent 111 so that movable vane is taken turns fan housing 1, determined impeller 3, motor
Casing 6, motor fan housing 7, motor drive and form effective gas channel between plate 11, cool down air-flow
Can be quickly through, and the heat that body produces is taken away, reach cooling-down effect.
More preferably, shown in Fig. 4, it is provided with through hole 71 at motor fan housing 7 vent, determines impeller and set
There is the securing member 32 matched with described through hole, make motor fan housing 7 quickly to install and use, even
The mode of connecing has multiple, is not limited only to this kind of connected mode, and such as, common bolt connects.
As in figure 2 it is shown, the longitudinal section of movable vane wheel fan housing 3 is turriform, setting is gathered to center in its one end,
And it is formed centrally within air inlet, the air sucked is had and certain gathers effect, carry at rotor 5
When movable vane takes turns 2 high speed rotating, can quickly and efficiently cooling gas be sucked.
Movable vane wheel 2 is fixedly connected on rotor 5, is placed in movable vane wheel fan housing 1, high-speed rotary
The rotor 5 turned drives movable vane to take turns, and is sucked by cooling gas and high speed centrifugation throws away.
Determining impeller 3 to be arranged on motor case 6, its outer face is fixedly connected on motor fan housing 7 and moves
Between impeller fan housing 1, and the end face being connected with motor fan housing 7 is provided with guiding gutter 31, and guiding gutter is by cold
But a gas part imports the vent being arranged on motor case 6 end, a part of guide motor casing
Outside 6.
Shown in Fig. 3, determine impeller 3 and be provided with guiding gutter 31, the various structures of guiding gutter 31, lead
Chute is made up of the guide vane 311 of multiple bendings, preferably 8, and guiding gutter 31 can be by a high speed
Cooling gas is directed to motor side, and the cooling gas of flow direction motor side passes through motor fan housing 7 and motor machine
The gap that shell 6 is formed, a part axially flowing, flow direction motor drives plate 11, and a part passes through sidewall
The vent 72 in portion flows out, and drives plate 11, motor case 6 to lower the temperature in motor.
When rotor 5 drives movable vane wheel 2 rotation, the centrifugal movable vane wheel 2 of high speed rotating will cooling
Air driven impeller fan housing 1 mouthful sucks and throws away the most at a high speed along impeller, and Fast Cooling air-flow passes through
Determine the guiding gutter 31 on impeller, a part of gas guide motor side that will cool down of guide vane 311, one
Divide and cooling gas is guided the vent being arranged on motor stator end, flow into the cooling gas of motor side
Stream, a part is led to by the air-flow formed by the gap between motor fan housing 7 sidewall and motor case 6
Road, axially flows along motor case 6, axially the gas of flowing leading to by motor fan housing 7 end
The gap that air port 10 and end are formed with motor fan housing 7 sidewall, blows to motor and drives plate 11, can
Power switch and electric capacity on plate 11 is driven with effective cooling.The cooling air-flow of remainder, passes through
The vent 10 of motor fan housing 7 side perimembranous flows out, owing to motor drives plate 11 to be arranged on motor fan housing
Outside 7 ends, and being not disposed on vent, do not have motor to drive the stop of plate 11, windage is less,
The work efficiency of blower of cleaner can be improved.
This utility model passes through to be provided with motor fan housing 7 outside motor case 6, and at motor fan housing 7
Side perisporium is provided with vent 72, drives plate 11 to be arranged in the motor being provided with vent 111 simultaneously
Outside motor fan housing 7 end, make movable vane wheel fan housing 1, determine impeller 3, motor case 6, motor fan housing
7, motor drives and forms gas channel between plate 11, and cooling gas is by these gas channels, it is achieved
Motor is driven the power switch on plate 11 and the cooling of electric capacity and the cooling of motor body.This practicality is new
Type can use in motor of dust collector or similar electric machine structure, has and takes away power switch and electric capacity
The heat produced, reduces power switch and the temperature of electric capacity, improves working life and the effect driving plate 11
The advantages such as rate.
Technology contents of the present utility model and technical characteristic have revealed that as above, but are familiar with the skill of this area
Art personnel are still potentially based on teaching of the present utility model and announcement and make all without departing substantially from this utility model
The replacement of spirit and modification, therefore, this utility model protection domain should be not limited to disclosed in embodiment
