Abstract
The utility model discloses a washing machine linkage switch structure with a U-shaped reed. The opening of the U-shaped reed faces towards the left side. An upper side rod of the U-shaped reed is fixed to the inner wall of the left side of a shell. A terminal is fixed to the inner wall of the shell. The right end of the terminal is located below the left end of a lower side rod of the U-shaped reed. Corresponding contacts are arranged at the right end of the terminal and the left end of the lower side rod of the U-shaped reed. A first swing rod is fixed to the inner wall of the right side of the shell. One end of the first swing rod makes contact with the right end of the lower side rod of the U-shaped reed. A reset spring is arranged below the first swing rod. A second swing rod is arranged on the inner wall of the lower side of the shell. The upper portion of the second swing rod is bent leftward and makes contact with the left end of the lower side rod of the U-shaped reed. A torsional spring is arranged below the bent portion of the second swing rod. By means of the washing machine linkage switch structure, the mechanical motions of uncovering and deflection eliminating can directly act on the reed, the structure is simple and reliable, cost is low, the middle mechanical conversion device is omitted, and the risk of mechanical conversion efficacy loss is eliminated.
Description
Technical field
The utility model relates to the safety switch technical field of washing machine, relates in particular to a kind of Washing machine linkage construction of switch with U-shaped reed.
Background technology
At present, having uncaps report to the police and the interlock of the washing machine of dehydration warning function to uncap be all first by cover plate, to promote cover plate fork to realize switch closure, washing machine dehydration procedure is normally worked.When occurring that cover plate for washing machine does not cover tightly, cover plate fork unclamps, and switch disconnects, and washing machine is reported to the police; When dehydration barrel amplitude of fluctuation is excessive, de-beat bar changes by the mode of mechanical switch de-inclined to one side warning of disconnection realization that cover plate fork pushing state could be realized switch.This type of linked switch structure relative complex, there is failure risk in mechanical switch structure, and cost is higher.
Utility model content
The utility model object is exactly in order to make up the defect of prior art, and a kind of Washing machine linkage construction of switch with U-shaped reed is provided.
The utility model is achieved through the following technical solutions:
A kind of Washing machine linkage construction of switch with U-shaped reed, include housing and U-shaped reed, the opening of U-shaped reed is towards left side, the upper side lever of U-shaped reed is fixed in the inner left wall of housing, in inner walls, be also fixed with terminal, the right-hand member of terminal is positioned at the left end below of the lower lateral rods of U-shaped reed, left end at the right-hand member of terminal and the lower lateral rods of U-shaped reed is provided with corresponding contact, on the inwall of the right side of housing, be fixed with fork one, the end of fork one contacts with the right-hand member of U-shaped reed lower lateral rods, below fork one, be provided with back-moving spring, on housing downside inwall, be provided with fork two, the top of fork two bending left and contact the left end of the lower lateral rods of U-shaped reed, below fork two dogleg section, be provided with torsion spring.
The corresponding cover plate for washing machine operating position of fork one, cover plate for washing machine is by realizing the racking to U-shaped reed right-hand member to the promotion of fork one; Back-moving spring makes fork one reliable reset also eliminate the misoperation that vibrations bring; The corresponding washing machine of fork two takes off inclined to one side operating position, and dehydration barrel is by realizing the racking to U-shaped reed left end point to the shock of fork two; Torsion spring makes fork two reliable reset and eliminates the misoperation that vibrations bring; U-shaped reed and terminal are realized switch by the mode cut-in operation loop of fast insert-pull; Reliable conducting is realized by electroplating the mode of the metals such as gold, silver in contact; The installation and positioning structure of supporting mechanism, electrical isolation and the switch that housing provides whole construction of switch on washing machine;
When cover plate for washing machine is opened or do not shut, U-shaped reed is in reset mode (for increasing reset reliability, increasing back-moving spring), and switch disconnects, and the now operation of de-two pairs of switches of beat bar is invalid, and switch is in breaking alarming state; When cover plate for washing machine is closed, cover plate fork one actuating spring right-hand member, make switch closed, make washing machine can carry out dehydration procedure, now de-beat bar under the effect of torsion spring in reliable reset state, vibrations except clashing into can not make the state of de-beat bar change, if it is excessive that dehydration barrel swing occurs, dehydration barrel is clashed into de-beat bar, thereby makes de-beat bar actuating spring left end, switch is disconnected, realize de-inclined to one side warning function.
The utility model has the advantages that: uncapping and de-inclined to one side warning function when the utility model can reliably be realized laundry machine dehydration, realization is uncapped and is taken off the direct effect of inclined to one side mechanical action to reed, simple and reliable for structure, with low cost, save intermediate mechanical conversion equipment, eliminate mechanical switch failure risk.

Fig. 2 is switch nature or the alarm condition structural representation of uncapping.
Fig. 3 is normal operating conditions structural representation.
Fig. 4 is de-inclined to one side alarm condition structural representation.
The specific embodiment
As Fig. 1, 2, 3, shown in 4, a kind of Washing machine linkage construction of switch with U-shaped reed, include housing 1 and U-shaped reed 2, the opening of U-shaped reed 2 is towards left side, the upper side lever of U-shaped reed 2 is fixed in the inner left wall of housing 1, at housing 1 inwall, be also fixed with terminal 3, the right-hand member of terminal 3 is positioned at the left end below of the lower lateral rods of U-shaped reed 2, left end at the right-hand member of terminal 3 and the lower lateral rods of U-shaped reed 2 is provided with corresponding contact 4, on the inwall of the right side of housing 1, be fixed with fork 1, the end of fork 1 contacts with the right-hand member of U-shaped reed 2 lower lateral rods, below fork 1, be provided with back-moving spring 6, on housing 1 downside inwall, be provided with fork 27, the top of fork 27 bending left and contact the left end of the lower lateral rods of U-shaped reed 2, below fork 27 dogleg section, be provided with torsion spring 8.
