Abstract
The utility model relates to an automatic electric cooker which is characterized in that an original electric heating plate is additionally provided with a pressure lever having a restoring spring, and the lower end of pressure lever is provided with a crank arm. Before the cooker body of the electric cooker is positioned on the electric heating plate, the pressure lever pushes a magnetic switch to an attracting state through the crank arm and under the function of the restoring spring; thus, an operating procedure that the magnetic switch must be made to enter the attracting state by hand when an existing electric cooker at present is used can be left out.
Description
The utility model relates to a kind of electric cooking appliance.
The present electric cooker of producing and using must be pressed the pressing plate of magnetic switch during use, just can enter heated condition.In case because of forgetting hastily pressing plate is pressed, has then just been wasted the time.I propose in utility model patent 91206417.X: adopt a depression bar, rely on the gravity of pot body, by mechanical transmission component, make electric cooker enter heated condition.This scheme is complicated, implements to have certain difficulty.
The purpose of this utility model is to provide a kind of process further improved electric cooker.It not only has the function that enters heated condition automatically, and implements easier.
The purpose of this utility model is achieved in that on the electric hot tray of electric cooker or other place, installs a depression bar that has back-moving spring, and an end of depression bar can contact and be subjected to the pressure of pot body with the pot body of electric cooker, and the other end is connected with mechanical transmission component.Before placing the pot body on the electric hot tray, depression bar, is placed a pot body to get ready so that be to attracting state (being the heated condition of electric cooker) by mechanical transmission component jack-up magnetic switch under the effect of back-moving spring.So just can save that original electric cooker is must armrest moving to make it enter the operating process of heated condition.When placing the pot body on electric hot tray, rely on the gravity of pot body to promote depression bar, depression bar promptly moves and drives mechanical transmission component and is separated from magnetic switch, so as for coming off voluntarily of magnetic switch be that electric cooker enters keeping warm mode and gets ready.When the gravity of pot body promotes the depression bar motion, make back-moving spring enter the energy storage state.After meal is carried out with the pot body when electric hot tray takes off, back-moving spring discharges energy stored and promptly promotes depression bar and turned back to original position when placing the pot body again, and make magnetic switch enter attracting state again by mechanical transmission component, think that to place the pot body once more ready.
The utility model is because easier than original scheme, so cost is lower, it is more acceptant to estimate everybody.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Accompanying drawing provides be fully automatic electric cooker add the thermal control schematic diagram.Below in conjunction with its working condition of description of drawings.
On the electric hot tray (1), near magnetic switch (a 2) installing depression bar that can move up and down (3), back-moving spring (4) is arranged on the depression bar (3) in the drawings, the lower end of depression bar (3) is connected with connecting lever (5).The pressing plate supporting with it (6) arranged below magnetic switch (2).The right-hand member of pressing plate (6) is a fulcrum, and left end is connected with the push rod (7) of magnetic switch (2), and push rod (7) is connected with magnet (9).Go up before the pot body of placing electric cooker at electric hot tray (1), depression bar (3) by connecting lever (5) and push rod (7), makes magnetic switch (2) remain on attracting state (shown in solid line among the figure) under the effect of back-moving spring (4).Simultaneously, the thimble (8) on the pressing plate (6) promotes auxiliary contact K
1(annotate: sectional pressure element does not draw in the drawings in closed sectional pressure element short circuit soon.General electric cooker all is to adopt when heated condition the sectional pressure element short circuit, when keeping warm mode sectional pressure element is serially connected in the electric power loop).But this moment is owing to the auxiliary contact K as power switch
2Be in open position, so this moment, electric cooker was in off-position.When going up placement pot body (a pot body does not draw in the drawings) toward electric hot tray (1), the gravity of pot body is depressed the upper surface of depression bar (3) and magnetic switch (2), make the upper end of depression bar (3) and the upper surface and the electric hot tray (1) of magnetic switch (2) remain on a plane (annotate: the upper surface of magnetic switch has spring to support, and can stretch).Connecting lever (5) move downward with depression bar (3) and and push rod (7) between cause certain interval (as shown in phantom in FIG.).Meanwhile, back-moving spring (4) is compressed; Auxiliary contact K
2The compressing of the thimble (10) on the compression rod (3) and closure are connected electric power loop, and electric cooker promptly enters heated condition.Along with the rising of temperature of boiler, when reaching " curie point " of magnetic switch (2), the inner magnet (9) of magnetic switch (2) promptly comes off voluntarily, and push rod (7) moves downward position shown in the dotted line among the figure with pressing plate (6), makes auxiliary contact K
1Disconnect, sectional pressure element is serially connected in the loop, and electric cooker promptly enters keeping warm mode.After meal is carried out with the pot body from electric hot tray (1) when taking off, depression bar (3) is subjected to the elastic force of back-moving spring (4) and moves upward, and by connecting lever (5) and push rod (7), drives magnet (9) again and pressing plate (6) turns back to original solid line position together.Make magnetic switch (2) return to attracting state again, auxiliary switch K
2Again electric power loop is cut off, so that ready for reusing.
Claims (1)
- A kind of fully automatic electric cooker, the temperature control part of this electric cooker divides and mainly is made up of magnetic switch and auxiliary contact, it is characterized in that the depression bar that adopts one to have back-moving spring, and an end of depression bar contacts with a pot body, and the other end is connected with mechanical transmission component.
