Description
Technical field
The utility model relates to a kind of control switch of washing machine, relates to a kind of telescopic laundry machine dehydration safety switch particularly, and it comprises the pedestal box, backs down bar, lance, switch reed and switch cover; Describedly back down bar and lance is articulated in the lower end of described pedestal box, and be respectively equipped with one and back down bar Partner and lance Partner; Described bar Partner and the lance Partner of backing down is movably arranged on backing down in bar opening and the lance opening at the bottom of the described pedestal box box respectively, and described switch reed is arranged in the described pedestal box.
Background technology
Safe on-off of washing machine is when guaranteeing laundry machine dehydration, when throwing open door closure or dehydration barrel generation eccentric operating, and the safety switching apparatus that dehydration barrel is stopped operating rapidly.Notification number is that the Chinese utility model patent of CN201084562Y discloses a kind of safe on-off of washing machine, and its switch upper reed plate is bent to form downward precompression downwards, and the upper reed plate bottom is provided with the contact spacing adjustment screw; The door closure open-close on-off triggers the curved arm lever that lever rises for the two ends sledge, and Partner directly acts on reed under the switch; Dehydration barrel is rocked the shutdown fork and is directly acted on the switch upper reed plate.In this technical scheme because switch triggering lever and shut down fork with the direct touch switch reed of positive force; when the movement range of switch triggering lever and shutdown fork is excessive; very easily cause the distortion of switch reed; and the safety switch closure of this technical scheme is to rely on the precompression of upper reed plate to realize fully; therefore; the distortion of upper reed plate will badly influence the closed contact force of switch reed, cause poor electric contact.As want limit switch to trigger lever and the back down amplitude of shutdown fork to upper reed plate; then the movement range of switch triggering lever and shutdown fork is restricted; cause the security control adaptive capacity of washing machine relatively poor, be difficult to satisfy the adjustment requirement that door for washing machine opens and closes amplitude and dehydration barrel shaking amplitude.
The utility model content
The technical problems to be solved in the utility model provides a kind of safe on-off of washing machine, its front and back active force that will back down the active force up and down of bar and lance by the segmental arc on the switch reed converts the left and right sides switch motion of switch reed to, thereby the movement range that makes the switch reed is not backed down bar and the lance motion amplitude influences, the amplitude of the backing down unanimity of maintained switch reed, the distortion that solves because of the switch reed causes safety switch poor electric contact problem.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of safe on-off of washing machine comprises the pedestal box, backs down bar, lance, switch reed and cover plate; Describedly back down bar and lance is articulated in the lower end of described pedestal box, and be respectively equipped with one and back down bar Partner and lance Partner; Described bar Partner and the lance Partner of backing down is movably arranged on backing down in bar opening and the lance opening at the bottom of the described pedestal box box respectively, and described switch reed is arranged in the described pedestal box; Described switch reed comprises first reed and second reed; Described first reed is vertical with second reed and is listed in the described pedestal box, and is respectively equipped with first segmental arc and second segmental arc; Describedly back down the side that bar Partner and lance Partner are arranged at described first segmental arc and second segmental arc respectively.Make the swing of backing down bar Partner and lance Partner promote described first reed and second reed by described first segmental arc and second segmental arc; Make the switch motion amplitude of described first reed and second reed do not backed down bar and the lance motion amplitude influences, avoided backing down that bar and lance motion amplitude are excessive causes the distortion of switch reed and cause the problem of safety switch poor electric contact, simultaneously, also give and back down bar and lance has increased bigger adjustment space, thereby improved the adaptive capacity of safety switch.
Adjustment for the closed gap of more convenient switch reed, as a kind of optimal technical scheme of the utility model, on two sidewalls of described pedestal box, be respectively equipped with a reed adjustment screw, offset with described first reed and second reed respectively, can adjust first reed and the second reed switch gap at any time by adjusting the reed adjustment screw, improve the application flexibility of safety switch.
Owing to back down the front end that bar is arranged on safety switch, its swing and make the swing amplitude of backing down the bar Partner less, as a kind of optimal technical scheme of the utility model, the described Partner that backs down bar is provided with an arcwall face, and action is more along sliding when making the Partner that backs down bar promote described second reed.
The thickness that backs down the bar Partner directly influences the sensitivity of backing down described second reed, for the ease of adjusting this sensitivity, as a kind of optimal technical scheme of the utility model, on described arcwall face, also be provided with the fixing arc of one one end, between be provided with arc-shaped groove; Be provided with one and back down adjustment screw in the described bar Partner outside of backing down, describedly back down adjustment screw and described arc offsets.Back down adjustment screw by adjustment described arc is ejected, increase and back down the thickness of bar Partner, thereby increase the sensitivity that described second reed is backed down.And, back down the adjustment of bar Partner thickness by this, the adjusting that the realization door for washing machine is opened height.
As a kind of optimal technical scheme of the utility model, described first segmental arc is near the front portion of described first reed; Described second reed is provided with a vertical section with respect to described first reed, and described second segmental arc is positioned at the bending part of described vertical section.Make described bar Partner and the lance Partner of backing down be and shift to install, make the structure of safety switch compact more, rationally.
As a kind of optimal technical scheme of the utility model, be provided with two reed troughs arranged side by side in the rear end of described pedestal box, described first reed and second reed are fastened on respectively in the described reed trough, thereby have simplified the assembling and the maintenance of safety switch.
The utility model has than the prior art safety switch: 1, simple in structure, parts are few; 2, switch motion power is little, reliable in action, highly sensitive, and Acceptable life is long; 3, the protective effect of dehydration barrel eccentric operating is strong, and the door closure Lift is regulated arbitrarily, and high conformity has thoroughly been eliminated the whole shortcomings of prior art.
