Abstract
Washing machine lid switch including the casing, stretches into the sound contact in the casing, and the head is by inside outwardly directed built -in the arguing for the sake of arguing of casing, built -in argue for the sake of arguing including the body of rod, body of rod afterbody be provided with with the fulcrum at the lower pressure point of movable contact spring crimping, body of rod middle part and body of rod head be provided with with the raising a little of washing machine door closure contact, the fulcrum of the body of rod is articulated with casing front end bottom, the casing upper end is provided with the closing cap, makes the sound contact arrange enclosed environment in.
Description
Technical field
This utility model is that the uncap switch of shutdown of rotary drum washing machine dehydration is improved, more particularly to a kind of good reliability is effective
The washing machine cover switch of life-span length.
Background technology
The control method of existing washing machine be with a kind of Special safety switch or open type lid switch and door sensor formula switch come
Control, its principle is that door Xiao other end of lever door closure is the lower contact head band of lid switch by door for washing machine lid
Turn on the jacking block top of insulator.Open contact reset under door closure stops after certain altitude to separate and power-off.
The main deficiency of existing switch has：
1. the design of switch is mostly open type or semi-enclosed, but switchs present position and having band detergent pollution
The lower airway indentation, there of aqueous vapor, the contact of switch is easy to be aoxidized because of open type design, causes loose contact and failure.
2. switch is normally closed type switch on washing machine, so the upper contact of switch is easily deformed and loses contact force
Cause loose contact and be not dehydrated.
3. because in view of height is uncapped and existing switch contact closing stroke is affected stroke less by height, so tactile
Point pressure is also relatively small, and time length has the oxide layer itself also cannot to rub, and causes contact resistance big and is not turned on.
The content of the invention
This utility model is directed to the deficiencies in the prior art, there is provided a kind of raising rubs to the contact oxidation layer of active and static contact
Wiping ability, so as to effectively prevent the contact oxidation of quiet movable contact spring, can the laundry of deformation that produces of the long secondary closure of effective compensation contact
Cover is switched.
To realize this utility model purpose, there is provided technical scheme below：Washing machine cover is switched, it is characterised in that including shell
Body, stretches into the active and static contact in housing, head by enclosure interior it is outwardly directed it is built-in argue for the sake of arguing, active and static contact end is provided with
Contact, it is built-in argue for the sake of arguing including the fulcrum in the middle part of the lower pressure point, the body of rod that the body of rod, body of rod afterbody are provided with movable contact spring is crimped and
Body of rod head is provided with raising a little of contacting with door for washing machine, and fulcrum and the housing forward end bottom of the body of rod are hinged, the housing
Upper end is provided with capping, active and static contact is placed in enclosed environment.
Preferably, being provided with a set screw in capping, set screw is contacted on static contact, is adjusted static contact and is moved
The distance between contact.
Preferably, the distance between active and static contact is labeled as D, lower pressure point is labeled as B, fulcrum to the horizontal range of fulcrum
A is labeled as to the horizontal range raised a little, the minimum point raised a little is labeled as D to the distance of peak, increases B sizes, reduces
With the ratio of A sizes and become large-sized D, C size constancies, the ratio of D and C is 1:2.
This utility model beneficial effect：It is built-in argue for the sake of arguing bring up closed shell can effective control switch contact antioxidation
Function.Change the ratio and angle of triggering fulcrum of arguing for the sake of arguing of existing form obtaining the expansion of closing of contact stroke, make switch
Contact force and friction oxide layer ability are doubled and strengthen contact reliability.The set screw of setting can effectively back-off contact it is long-term
The deformation of closure and the high consistency of uncapping of controllable door closure.
Description of the drawings
Fig. 1 is this utility model front view.
Specific embodiment
Embodiment 1：Washing machine cover is switched, including housing 1, stretches into the active and static contact in housing 1（2、3）, head is by housing
It is internal it is outwardly directed it is built-in argue for the sake of arguing 4, active and static contact（2、3）End is provided with contact（2.1、3.1）, two contacts
（2.1、3.1）In cross arrangement, built-in arguing for the sake of arguing 4 includes that the body of rod 4.1, body of rod afterbody are provided with pushing of crimping with movable contact spring
Point 4.2, the fulcrum 4.3 in the middle part of the body of rod and body of rod head be provided with contact with door for washing machine raise a little 4.4, the body of rod is propped up
Point 4.3 is hinged with the front bottom end of housing 1, and the upper end of the housing 1 is provided with capping 5, makes active and static contact（2、3）It is placed in enclosed environment
In.A set screw 6 is provided with capping 5, set screw 6 is contacted on static contact 3, is adjusted between static contact 3 and movable contact spring 2
Distance.Fixed screw 7 is provided with capping 5 and is fastenedly connected covering 5 with housing 1.The distance between active and static contact is labeled as
D, lower pressure point to the horizontal range of fulcrum is labeled as B, and fulcrum to the horizontal range raised a little is labeled as A, raises minimum point a little
Distance to peak is labeled as D, increases B sizes, reduce with the ratio of A sizes and become large-sized D, C size constancies, D and C
Ratio be 1:2.
Change the ratio and angle of triggering fulcrum of arguing for the sake of arguing of existing form obtaining the expansion of closing of contact stroke, make switch
Contact force and friction oxide layer ability double and strengthen contact reliability.
Claims (3)
1. washing machine cover is switched, it is characterised in that including housing, stretch into the active and static contact in housing, head is outside by enclosure interior
Stretch out it is built-in argue for the sake of arguing, active and static contact end is provided with contact, and built-in being argued for the sake of arguing be provided with and move including the body of rod, body of rod afterbody
