The embodiment for examining accompanying drawing description is exemplary, is only used for explaining the utility model, and it is not intended that to of the present utility model
Limitation.
In description of the present utility model, it is to be understood that term " " center ", " length ", " on ", " under ", " left side ",
The orientation or position relationship of the instruction such as " right side ", " top ", " bottom ", " interior ", " outer ", " axial direction ", " radial direction ", " circumference " are based on accompanying drawing
Shown orientation or position relationship, it is for only for ease of description the utility model and simplifies description, rather than indicates or imply institute
The device or element of finger must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this reality
With new limitation.
The utility model provides a kind of electric motor end cap, and the electric motor end cap includes end cap body 100, in end cap body 100
Outer 101 on formed with ring-type solidus portion 200.Ring-type solidus portion 200 is provided with the breach 220 for dripping.In this feelings
Under condition, when end cap using when can be fixed on the both sides of motor stator 1, due to can typically be provided with control electricity in the side of motor
The electronic control component of machine rotating manner, for example, driver 5, the rat tail between electronic control component and motor, Ke Yitong
The solidus portion 200 for crossing ring-type is fixed on the outer 101 of end cap.In addition, solidus portion 200 is formed as ring-type, can connect fixed
As the ring that drips while wiring beam, dripped with water by breach 220.That is, when motor entering water, water droplet is along connecting line
Beam is moved to solidus portion 200, falls on the outside of motor along breach 220 under gravity, without into Electronic Control
Element causes motor to burn machine.
Solidus portion 200 can be integrally formed with end cap body 100.Preferably, solidus portion 200 be formed as from outer 101 to
The outer claw for extending and turning back, for example, solidus portion 200 can be the back-off formed on end cap edge 101.In such case
Under, when rat tail is fixed on the inside in solidus portion 200, certain sky should be left between rat tail and solidus portion 200
Between, i.e. the internal diameter in ring-type solidus portion 200 should be done big as best one can, more than the diameter of rat tail.So, solidus portion 200 is to even
The not caused fastening force of wiring beam.When water droplet is moved to solidus portion 200 along rat tail, effect of the water droplet in gravity
Lower vertical drop, falls on the outside of motor, and then effectively prevent electronic control component water inlet.
In addition, the concrete shape in solidus portion 200 can be varied, as long as can house and be fixedly connected with wire harness i.e.
Can.The cross sectional shape in solidus portion 200 can be U-shaped, semicircle or the annular with opening.As shown in Fig. 2 solidus portion 200 is wrapped
Include folded walls 210.A part 211 for folded walls is connected with end cap body 100, the end direction of another part 212 of folded walls
End cap body bends and breach 220 is formed between the end of a part 211 for folded walls.In this case, rat tail
The inside in solidus portion 200 can be caught at breach 220.
Further, in order to protect rat tail not to be worn when being caught in solidus portion, the both ends of folded walls 210 are set
There is guide portion 213 prominent toward each other.Guide portion 213 is formed as inclined eight word at a pair of centers towards solidus portion 200
Shape guide surface.Thus, you can so that rat tail to be easily caught in the inside in solidus portion 200, rat tail can be protected not again
By end wear.
In the above-described embodiment, formed with the centre bore 20 for connecting rotor 2 at the center of end cap body 100.
Around centre bore 20 formed with axially projecting annular wall 102 on end cap body 100.Formed between annular wall 102 and outer 101
There are multiple reinforcements 103.Solidus portion 200 is formed between two reinforcements in multiple reinforcements 103.Specifically, end cap sheet
Body 100 can be formed as a flat board for being of a generally tetragonal shape, in the center of flat board formed with axially extended certain high
The circular tube shaped centre bore 20 of degree.In the edge of close flat board formed with the annular wall 102 for being of a generally tetragonal shape.Close to flat board
Four angles between annular wall 102 and outer 101 formed with multiple reinforcements 103.Solidus portion 200 can be formed in square
The center on one side of flat board.
Because solidus portion 200 does not produce fastening force to rat tail, therefore, in order to prevent rat tail from rocking, solidus
Portion 200 sets height should be less than the height of rat tail.So, rat tail can pull down and from being fixed on solidus portion 200
In, it will not rock.Preferably, electric motor end cap is made of aluminum.
The utility model additionally provides a kind of electric machine assembly.Electric machine assembly includes rotor 2, is looped around determining for the outside of rotor 2
Son 1 and the electric motor end cap 3 installed in the both sides of stator 1.Electric machine assembly also includes being used for controlled motor installed in the side of motor
The driver 5 of rotating, wherein, the electric motor end cap between stator 1 and driver 5 is above-mentioned electric motor end cap.Solidus portion 200 uses
Rat tail between fixed motor and driver 5.
The utility model additionally provides a kind of washing machine.Washing machine includes housing, the roller being arranged in housing and set
Put and drive the electric machine assembly of the drum functions in the lower section of roller.Electric machine assembly is above-mentioned electric machine assembly, and solidus portion lacks
Mouth 220 is directed downward.In this case, when the roller leak of washing machine enters the motor of lower section, water droplet can be along connection
Wire harness flow to solidus portion 200, drops onto the outer of motor at opening direction breach 220 directed downwardly under gravity afterwards
Portion, will not enter electronic control component causes motor to burn machine.
Preferred embodiment of the present utility model, still, the utility model and unlimited is described in detail above in association with accompanying drawing
In this.In range of the technology design of the present utility model, a variety of simple variants can be carried out to the technical solution of the utility model,
It is combined in any suitable manner including each particular technique feature.In order to avoid unnecessary repetition, the utility model
Various combinations of possible ways are no longer separately illustrated.But these simple variants and combination should equally be considered as the utility model institute
Disclosure, belong to the scope of protection of the utility model.
