Abstract
The motor includes following parts: stator enwound wire of making current passing through; rotor setup outer side of the stator, and keeping up a certain internal between rotor and stator, rotor is rotated when stator is connected to power source; rotative frame connected to rotor, the frame including an integrated connection part for fixing the rotor. In the invention, rotor is fixed on internal side face of rotative frame without need of individual connection part. Thus, structure of the motor is simplified, and assembling steps and time are reduced. The invention reduces defective rate.
Description
Technical field
The present invention relates to a kind of external-rotor motor that is installed in the washing machine, particularly relate to a kind of can with the rotor of external-rotor motor need not be independent link but the direct external-rotor motor by the fixing washing machine of rotary frame.
Background technology
In general, washing machine be a kind of utilize washing tube or be arranged on mechanical rotation power that the impeller of washing tube bottom produces come to clothing wash, the device of rinsing and dehydration.Mainly comprise to the method for washing tube or impeller the transmission of power of drive motors in the washing machine: by the indirect transfer method of motor pulley; And the rotating shaft of washing tube or impeller is directly connected on the external rotor of motor, the rotary power of motor is directly passed to the method for rotating shaft by the rotation of external rotor.Fig. 1 is the washing machine vertical structure cutaway view of prior art.Fig. 2 is the washing machine external-rotor motor cutaway view of prior art.As shown in Figure 1, the motor of this prior art washing machine mainly comprises: stator 14 and rotary frame 16.Wherein stator 14 is fixed on the downside of the bearing spider 18 that is arranged at outer washing tube 24 bottoms; Rotary frame 16 then is connected its centre by attachment screw 8 lower end of driving shaft 10.When the motor energized, rotary frame 16 can rotate, and drives driving shaft 10 simultaneously and is rotated, and rotate impeller 20 or interior washing tube 22 selectively by clutch 12.And as shown in Figure 2, the outer peripheral face inboard of rotary frame 16 is set with the rotor of being made by permanent magnet 3.Might make to produce between rotor 3 and the rotary frame 16 during rotor 3 rotations and relatively move, bottom in order to prevent this problem from the upper end of rotor 3 to rotary frame 16 is provided with a plurality of rivets 1, rotor 3 is fixed on the inboard of rotary frame 16 by these rivets 1.But, need independent rivet 1 that rotor 3 is fixed on the rotary frame 16 owing to have the external-rotor motor of the washing machine of said structure, not only required material is more, complex structure, and also accepted product percentage also can descend, and operational sequence increases.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind ofly to need not independent link and just rotor can be directly connected on the rotary frame, can save Master Cost, simplified structure thus, reduce fraction defective, and the external-rotor motor of the washing machine of simplified operation operation.
In order to achieve the above object, the external-rotor motor of washing machine provided by the invention comprises: the outside is tied with the stator that can make the coil that electric current passes through; Be arranged on the outside of stator, the rotor that when the stator energized, can rotate mutually across a certain distance with stator; With the rotary frame that links to each other with rotor, be formed with the connecting portion that rotor can be fixed on the inner circumferential surface on the described rotary frame.
The external-rotor motor of washing machine provided by the invention is that rotor is fixed on the medial surface of rotary frame, need not independent link, so not only can simplify the structure of motor, reduce assembling procedure and time, but also can reduce fraction defective, and can reduce manufacturing cost.
Description of drawings
Be elaborated below in conjunction with the external-rotor motor of the drawings and specific embodiments to washing machine of the present invention.
Fig. 1 is the washing machine vertical structure cutaway view of prior art.
Fig. 2 is the washing machine external-rotor motor cutaway view of prior art.
Fig. 3 is a washing machine external-rotor motor cutaway view of the present invention.
Embodiment
As shown in Figure 3, the external-rotor motor of washing machine provided by the invention comprises: the rotary frame 21 that the centre links to each other with driving shaft 26; Be positioned at the inside of rotary frame 21, and be fixedly installed on the stator 24 of motor cover 27 downsides; On the medial surface that is positioned at rotary frame 21, radially be provided with in opposite directions with stator 24, and the rotor of making by permanent magnet 22.Be formed with corresponding connecting hole 30 on stator 24 and the motor cover 27 respectively, it is fastening with the one end with nut 29 that screw 28 runs through connecting hole 30 backs, so just stator 24 can be fixed on the downside of motor cover 27.In addition, for rotor 22 being fixed on the inner peripheral surface of rotary frame 21, the upper end of rotary frame 21 to the inside with
The shape bending is to push down the upper end of rotor 22.Be tied with coil 25 on the outer peripheral face of stator 24, on coil 25 after the motor energized, will there be electric current to flow through, therefore can produce rotation torque between stator 24 and rotor 22, rotor 22 will rotate to a line of least resistance this moment, driven rotary frame 21 rotation thereupon simultaneously.When rotary frame 21 rotates simultaneously with the rotor 22 that is fixedly installed on rotary frame 21 inboards, may produce between rotary frame 21 and the rotor 22 and relatively move, because the upper end of rotary frame 21 bends to the inside, so it can be fixed the upper end of rotor 22, what can prevent from thus between rotary frame 21 and the rotor 22 to occur relatively moves, thereby rotor 22 is securely fixed on the rotary frame 21 more.In addition, the centre, lower end of rotary frame 21 is formed with the spliced eye 31 that can insert driving shaft 26.After the revolving force of rotor 22 passed to driving shaft 26, the not shown clutch that links to each other with driving shaft 26 can rotate impeller or interior washing tube selectively.Promptly when carrying out washing operation, be connected with impeller; And when carrying out dehydrating operations, link to each other with interior washing tube with impeller simultaneously, thereby rotary power is passed to impeller and interior washing tube, to finish washing or dehydrating operations.
