Abstract
The purpose of the present invention is to propose to a kind of easy for installation, control reliable temp. limit device for electric cooker.The temp. limit device for electric cooker of the present invention is made up of interior cup, outer cup, and described interior cup is supported in outer cup by outer spring；The top of described interior cup is provided with soft magnetism by aluminium lid, soft magnetism torr, and the lower removable of interior cup is provided with Hard Magnetic torr, is provided with inner spring between the inner top surface of Hard Magnetic torr and interior cup；Being fixed with Hard Magnetic in Hard Magnetic torr, the bottom of Hard Magnetic torr connects pull bar, and pull bar sequentially passes through downwards interior cup, outer cup；It is critical only that described pull bar is cylinder.Cylindrical pull bar does not have sharp edge, and thus without scratching workman, and cylinder is the most pliable, and therefore length and the shape of pull bar all will not change, it is ensured that switch is controlled in its stroke by Hard Magnetic torr.
Description
Technical field
The invention belongs to electrical equipment manufacturing technology field, be related specifically to a kind of temp. limit device for electric cooker.
Background technology
Temp. limit device for electric cooker is typically made up of interior cup, outer cup, and interior cup is supported in outer cup by outer spring, and interior cup is provided with prerotation vane, and outer cup is provided with pilot hole, for the motion guide of interior cup；Interior cup top is provided with soft magnetism by aluminium lid, soft magnetism torr, and the lower removable of interior cup is provided with Hard Magnetic torr, and Hard Magnetic torr is fixed with Hard Magnetic, and the bottom of Hard Magnetic torr connects pull bar, pull bar sequentially pass through downwards interior cup, outer cup and be connected with the switch of electric cooker.It is provided with inner spring between the inner top surface of Hard Magnetic torr and interior cup.
In use, interior pot press against aluminium lid and makes interior cup down press, and makes aluminium lid contact with the interior pot the bottom of a pan.When connecting the switch of electric cooker, pull bar up promotes Hard Magnetic torr to overcome the elastic force of inner spring, makes soft magnetism, Hard Magnetic adhesive.When meal is ripe, the temperature of soft magnetism reaches Curie temperature, so that the permeability of soft magnetism drastically declines, now the suction between soft magnetism, Hard Magnetic can be less than the elastic force of inner spring, and Hard Magnetic torr is depressed by the elastic force of inner spring, thus driven switch circuit breaking by pull bar.
Current pull bar is sheet metal, the most easily scratches workman, and the insufficient strength of pull bar, easy bending deforms, therefore, it is difficult to ensure the accuracy of electric cooker on-off control.
Summary of the invention
The purpose of the present invention is to propose to a kind of easy for installation, control reliable temp. limit device for electric cooker.
The temp. limit device for electric cooker of the present invention is made up of interior cup, outer cup, and described interior cup is supported in outer cup by outer spring；The top of described interior cup is provided with soft magnetism by aluminium lid, soft magnetism torr, and the lower removable of interior cup is provided with Hard Magnetic torr, is provided with inner spring between the inner top surface of Hard Magnetic torr and interior cup；Being fixed with Hard Magnetic in Hard Magnetic torr, the bottom of Hard Magnetic torr connects pull bar, and pull bar sequentially passes through downwards interior cup, outer cup；It is critical only that described pull bar is cylinder.
In use, interior pot press against aluminium lid and makes interior cup down press, and makes aluminium lid contact with the interior pot the bottom of a pan.When connecting the switch of electric cooker, pull bar up promotes Hard Magnetic torr to overcome the elastic force of inner spring, makes soft magnetism, Hard Magnetic adhesive.When meal is ripe, the temperature of soft magnetism reaches Curie temperature, so that the permeability of soft magnetism drastically declines, now the suction between soft magnetism, Hard Magnetic can be less than the elastic force of inner spring, and Hard Magnetic torr is depressed by the elastic force of inner spring, thus driven switch circuit breaking by pull bar.
Cylindrical pull bar does not have sharp edge, and thus without scratching workman, and cylinder is the most pliable, and therefore length and the shape of pull bar all will not change, it is ensured that switch is controlled in its stroke by Hard Magnetic torr.
Further, for convenience of installing, the upper and lower of described pull bar is equipped with annular groove；The bottom of described Hard Magnetic torr is provided with the major arc shape clamp of a side opening, and the annular groove on described pull bar top is stuck in described major arc shape clamp, to realize the connection of pull bar and Hard Magnetic torr.
The temp. limit device for electric cooker of the present invention is by changing the shape of pull bar so that it is assembles convenient, will not scratch workman, and the control that electric cooker can be made to switch is relatively reliable, therefore have good practicality.
Accompanying drawing explanation
Fig. 1 is the structural representation of the temp. limit device for electric cooker of the present invention.
Fig. 2 is the structural representation of the pull bar of the present invention.
Fig. 3 is the structural representation of the major arc shape clamp of the present invention.
Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, the detailed description of the invention such as mutual alignment between the involved shape of each component, structure, each several part and annexation, the effect of each several part and operation principle etc. of the present invention is described in further detail.
Embodiment 1:
As it is shown in figure 1, the temp. limit device for electric cooker of the present embodiment is made up of interior cup 1, outer cup 2, described interior cup 1 is supported in outer cup 2 by outer spring 3；The top of described interior cup 1 is provided with soft magnetism 6 by aluminium lid 4, soft magnetism torr 5, and the lower removable of interior cup 1 is provided with Hard Magnetic torr 7, is provided with inner spring 8 between the inner top surface of Hard Magnetic torr 7 and interior cup 1；Being fixed with Hard Magnetic 9 in Hard Magnetic torr 7, the bottom of Hard Magnetic torr 7 connects has pull bar 10, pull bar 10 to sequentially pass through downwards interior cup 1, outer cup 2；It is critical only that described pull bar 10 is cylinder.
Cylindrical pull bar 10 does not have sharp edge, and thus without scratching workman, and cylinder is the most pliable, and therefore length and the shape of pull bar 10 all will not change, it is ensured that switch is controlled in its stroke by Hard Magnetic torr 7.
As shown in Figure 2,3, for convenience of installing, the upper and lower of described pull bar 10 is equipped with annular groove 11；The bottom of described Hard Magnetic torr 7 is provided with the major arc shape clamp 12 of a side opening, and the annular groove 11 on described pull bar 10 top is stuck in described major arc shape clamp 12, to realize the connection of pull bar 10 and Hard Magnetic torr 7.
