Abstract
The utility model discloses a washing machine safety door switch mechanism, upper cover and casing pass through the fix with screw, are equipped with top and bottom clamp plate, support between upper cover and the casing bottom, connect through elastic element between upper cover, upper and lower clamp plate, the casing, press the tongue to fix and stretch out outside the casing behind the bottom clamp plate tip, take back door closure tip. The utility model discloses simple structure, dependable performance, commonality are good, can separate the opening height of door closure and the bucket function of hitting, even elastic element (spring or reed etc.) warp gradually, also can avoid frequently hitting the bucket.
Description
Technical field
The utility model relates to the utility model and relates to a kind of part of washing machine, and specifically the utility model relates to a kind of novel impeller automatic washing machine safety door switch.Belong to the washing machine field of mechanical technique.
Background technology
The impeller automatic washing machine is when dehydration, dehydration barrel is in the high speed rotating state, for fear of human body is damaged, when door for washing machine is opened to certain altitude, door switch must disconnect, in addition, when the clothing in the washing machine departed from the center of dehydration barrel, strong vibration took place in interior bucket when making dehydration, when vibration is arrived to a certain degree greatly, will touch the lance of door switch, washing machine is intake again then, repairs balance.
Traditional safety door switch uses the promotion slide block of arguing for the sake of arguing, thereby makes two reed contacts up and down.The Lift of door closure depends on the pre-pressing force of reed down, and along with the distortion of reed, the Lift of door closure can decrease, the thrust of reed reduces up and down, when causing laundry machine dehydration because the clothing unbalance loading, the steel ladle circle frequently rushes open door switch, finally causes machine normally to dewater.
The utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of washing machine safety door switching mechanism, simple in structure, dependable performance, versatility be good, can and hit a barrel functional separation with the Lift of door closure, even flexible member (spring or reed etc.) is out of shape gradually, also can avoid frequently hitting bucket.
The utility model is achieved through the following technical solutions: a kind of washing machine safety door switching mechanism, loam cake and housing by screw fix, door switch is provided with lance, it is characterized in that connecting by flexible member between loam cake, upper and lower pressing plate, the housing, stretch out outside the housing after pressing tongue to be fixed on the lower platen end, also be provided with support between the last lower platen, ride over door closure end, back.
The beneficial effects of the utility model are: the utility model is simple in structure, dependable performance, versatility are good, can and hit a barrel functional separation with the Lift of door closure, even flexible member (spring or reed etc.) is out of shape gradually, also can avoid frequently hitting bucket.
Description of drawings
Fig. 1 is an action principle schematic diagram of the present utility model;
Fig. 2 is a lower platen connected mode schematic diagram on the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of the present utility model in detail:
Shown in Fig. 1,2, when door for washing machine 1 is in closure state, press tongue 2 to promote top board 3-1, top board 3-1 is delivered to lower platen 3-2 by compression spring 4 with power again, because the leverage of lower platen 3-2 can guarantee that the clutch block 6 that is contained in this moment on the lower platen 3-2 is in contact condition with following inserted sheet 7; When opening door closure 1, because the effect of compression spring 4, top board 3-1 counterclockwise rotates around its turning cylinder, the decrement of above compression spring diminish, when two compression springs up and down during to the opplied moment equal and opposite in direction of lower platen 3-2, be this moment door switch closed with the critical condition that disconnects.When the laundry machine dehydration unbalance loading was excessive, the steel ladle circle bumped against the lance 5 of door switch, and lance is stirred lower platen 3-2, made clutch block 6 and following inserted sheet 7 disconnect the function that has promptly realized hitting barrel switch.
Below disclose the utility model with preferred embodiment, so it is not in order to restriction the utility model, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within the protection domain of the present utility model.
