Although above-mentioned scheme has many advantages, such as the above, they all have door of washing machine and can not normally closed
The problem of washing machine is still within "on" position, influence safety in utilization when closing.
The content of the invention
The purpose of this utility model is that there is provided a kind of stability is high and can carry in view of the above-mentioned problems existing in the prior art
Power-off protection mechanism in the washing machine door switch of high washing machine security.
The purpose of this utility model can be realized by following technical proposal：
A kind of power-off protection mechanism in washing machine door switch, washing machine door switch includes the internal shell for cavity
There is the gate stop mouthful being embedded in for gate stop, it is characterised in that mechanism includes slide plate, switch and spring, described on body, the housing
There is guide rail, above-mentioned slide plate is located at guide rail and can translated along guide rail, and above-mentioned slide plate outer end, which has, to be used for and gate stop side in housing
The contact site of portion's contact, above-mentioned spring is located between slide plate the inner and housing and had in the elastic force effect lower skateboard outer end of spring
The trend stretched at gate stop mouthful, above-mentioned switch is connected in housing, and the slide plate sidepiece has under recessed recess, above-mentioned switch
End, which is embedded in recess and switched in the state, cuts off washing machine, and contact site is pushed away by gate stop after gate stop insertion gate stop mouthful
Squeeze, slide plate overcomes spring force to that can make switch disengaging recess after its inner place translation and is resisted against slide plate sidepiece, the contact
There is the transition part seamlessly transitted, having at transition part is used to increase the reinforcement structure of its intensity between portion and slide plate.
During the normal use of washing machine, gate stop can stablize embedded gate stop mouthful when door of washing machine is closed.Now, slide plate outer end
Pushed by gate stop, so that the recess on slide plate departs from switch, now, switch does not disconnect washing machine.
When door of washing machine does not have normal switching-off, it is intraoral that gate stop would not be embedded in gate stop.Now, bullet of the slide plate in spring
To translation at its outer end under power effect, switch is embedded in indent after movement, and the switch after action disconnects washing machine, effectively
Avoid door of washing machine from there is no washing machine during normal switching-off to be still powered on work.
The setting of transition part can be such that contact site is steadily contacted with gate stop, that is to say, that contact site is not by housing upper rail
Influence, the contact that contact site can be made more to stablize with gate stop.

Place.
In power-off protection mechanism in above-mentioned washing machine door switch, the length phase of the plate body one and plate body two
Together, the length of the plate body three is more than the length of plate body one.
Because stress is maximum in the middle part of transition part and contact site, therefore, the situation of material consumption is not being increased by the structure
It is lower to increase its intensity as far as possible.
In power-off protection mechanism in above-mentioned washing machine door switch, the length of plate body three is the length of plate body one
3-5 times.
In power-off protection mechanism in above-mentioned washing machine door switch, the slide plate outer end has the reinforcement run through
Chamber, the reinforcement intracavitary has the stiffener of lattice-shaped, and above-mentioned plate body three is connected on stiffener.
Material consumption can be reduced by strengthening the setting of chamber, and because whole slide plate is plastic material, moreover it is possible to appropriate increase
Its plasticity, can water level deformation, it is to avoid fracture.
In power-off protection mechanism in above-mentioned washing machine door switch, the recess side has what is seamlessly transitted to lead
Enter portion.
In power-off protection mechanism in above-mentioned washing machine door switch, described introduction part is inclined plane.
In power-off protection mechanism in above-mentioned washing machine door switch, described introduction part is curved cambered surface.
The setting of introduction part can switch smoothly to be embedded in recess or because indent departs from.
In power-off protection mechanism in above-mentioned washing machine door switch, two are fixed with the housing and is symmetrical arranged
Guide plate, the opposite sides of the guide plate are respectively provided with the recessed guide groove being vertically arranged, and above-mentioned switch both sides have protrusion
Guiding rib and guiding rib be embedded at corresponding guide groove.
The setting of guide plate can make switch smoothly upper and lower translation, it is ensured that the stability of switch opening and closing.
Compared with prior art, the power-off protection mechanism in this washing machine door switch is due to the contact site energy of slide plate outer end
It is steadily contacted with gate stop formation, therefore, its stability is higher, once door of washing machine does not have normal switching-off, mechanism will can be washed
The power supply of clothing machine is cut off in time, with very high practical value.
Meanwhile, the setting of reinforcement structure can make the corner of substantially L-shaped slide plate have sufficient intensity, improve mechanism
Stability.
