Description
Technical field
The present invention relates to a kind of temp control switch, refer in particular to a kind of electric cooker full-automatic temperature limiting center switch that is used for electric cooker.
Background technology
The existing employed temperature limit switch of electric cooker, be by manually lever being pressed energized, begin to cook, the ripe back of meal temperature limit switch switches to keeping warm mode with circuit by heated condition through lever bindiny mechanism, because bindiny mechanism's link is too much, and each part dimension deviation accumulation, packaging technology mismate in addition, or factor such as user misoperation, make electric cooker normal appearance in the actual use of user give birth to phenomenons such as rice, half-cooked rice, burnt meal, even burn out the tragedy that heating board causes fire.
Summary of the invention
Purpose of the present invention aims to provide a kind of simple for assembly process, easy to use, safe and reliable a kind of electric cooker full-automatic temperature limiting center switch.
The purpose of this utility model is achieved in that a kind of electric cooker full-automatic temperature limiting center switch, comprise shell, be fixed on the back-moving spring on the outer casing inner wall, the spring that is reset is lifted the temperature detector in chamber in the enclosure, wherein: described temperature detector inner top is fixed with temperature sensitive magnet, be fixed with unit switch in the temperature detector bottom, between temperature sensitive magnet and unit switch, be provided with permanent magnet, be provided with inner spring in the periphery of temperature sensitive magnet and permanent magnet; It is relative with the permanent magnet bottom that described unit switch top is provided with the last feeler lever that can influence on off state, it is relative with the inner bottom part of shell that the bottom of unit switch is provided with the following feeler lever that can influence on off state, and unit switch also is provided with the power supply terminal of current input terminal, the heating terminal of drawing switching signal and insulation terminal.
Permanent magnet described in the above-mentioned electric cooker full-automatic temperature limiting center switch can be fixed on the pallet, and inner spring is fixed between the inner top of pallet and temperature detector.
After the present invention adopts said structure, make power switch signal to transmit via lever bindiny mechanism, avoided component processing scale error accumulation because of bindiny mechanism, mounting process mismate or misoperation of users produce gives birth to bad phenomenon such as rice, burnt meal, half-cooked, dry combustion method, and can simplify the packaging technology of electric cooker; Compared with prior art, have advantage easy to use, safe and reliable, because of reducing lever bindiny mechanism, also can reduce production costs simultaneously.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the present invention is described in further detail, but does not constitute any limitation of the invention.
Fig. 1 is the structural representation of a kind of specific embodiment of the present invention;
Fig. 2 is a working state schematic representation of the present invention;
Fig. 3 is a keeping warm mode schematic diagram of the present invention.
Among the figure: feeler lever, 43-power supply terminal, 44-heating terminal, 45-are incubated terminal under 1-shell, 2-back-moving spring, 3-temperature detector, the temperature sensitive magnet of 31-, 32-permanent magnet, 33-inner spring, 34-pallet, 4-unit switch, the last feeler lever of 41-, the 42-.
Embodiment
Consult shown in Figure 1, electric cooker full-automatic temperature limiting center switch of the present invention, comprise shell 1, be fixed on the back-moving spring 2 on shell 1 inwall, the spring 2 that is reset is lifted at shell 1 inner chamber and can be gone up, mobile down temperature detector 3, be fixed with temperature sensitive magnet 31 at temperature detector 3 inner tops, temperature detector 3 bottoms be fixed with can with on, mobile down unit switch 4, between temperature sensitive magnet 31 and unit switch 4, be provided with permanent magnet 32, periphery at temperature sensitive magnet 31 and permanent magnet 32 is provided with inner spring 33, permanent magnet 32 is fixed on the pallet 34, inner spring 33 is fixed between the inner top of pallet 34 and temperature detector 3, makes permanent magnet 32 change adhesive or to break away from temperature sensitive magnet 31 because of temperature sensitive magnet 31 magnetism intensities; Unit switch 4 tops be provided with can influence on off state on feeler lever 41 relative with permanent magnet 32 bottoms, it is relative with the inner bottom part of shell 1 that the bottom of unit switch 4 is provided with the following feeler lever 42 that can influence on off state, be provided with the power supply terminal 43 of current input terminal in following feeler lever 42 sides of unit switch 4, be provided with the heating terminal 44 and the insulation terminal 45 of drawing switching signal in the side of unit switch 4.
Operation principle of the present invention sees also Fig. 1, Fig. 2, shown in Figure 3, in Fig. 1, show, when electric cooker is put into empty pot or during with the pot taking-up, because of the pot compression reseting spring 2 or in not having of pot shortage in weight in empty with compression reseting spring 2, temperature detector 3 drive unit switches 4 move up under the effect of back-moving spring 2, the bottom surface that following feeler lever 42 breaks away from shell 1 inner chamber is vacant, and electric current flows into from insulation terminal 45 through power supply terminal 43 and flows out, and the electric cooker circuit is switched to keeping warm mode.
In Fig. 2, show, when electric cooker is put into real pot, oppressing temperature detector 3 because of the action of gravity of pot in real moves down with the unit switch 4 that is fixed on temperature detector 3 bottoms, the following feeler lever 42 of unit switch 4 is touched by the bottom surface of shell 1 inner chamber, electric current flows into from heating terminal 44 through power supply terminal 43 and flows out, the electric cooker circuit enters heated condition, and this moment, back-moving spring 2 was compressive state.
In Fig. 3, show, owing to losing magnetic conductivity, temperature sensitive magnet 31 make the temperature sensitive magnet 31 that always is pulled together under the elastic force effect of inner spring 33, separate reach temperature when cooking after with permanent magnet 32, permanent magnet 32 moves down the last feeler lever 41 that touches unit switch 4, cause electric current to switch to insulation terminal 45 by heating terminal 44 and flow out, the electric cooker circuit switches to keeping warm mode by heated condition; Pot in interior pot bottom temperature descends or takes out, temperature detector 3 temperature will descend thereupon, when reaching reset temperature, temperature sensitive magnet 31 recovers magnetic conductivity, the suction-combining force of permanent magnet 32 and temperature sensitive magnet 31 is during greater than inner spring 33 elastic force and permanent magnet 32 own wts, both again adhesive reset, the last feeler lever of unit switch 4 41 disengages with permanent magnet 32 and resets, the electric cooker circuit returns to initial condition.
