Description
Technical field
The utility model relates to a kind of electric-heating cooking utensil, relates in particular to a kind of electric-heating cooking utensil sensing device.
Background technology
At present, electric-heating cooking utensil is convenient fast because of it, is used by people just more and more.In recent years, along with the continuous development of computer technology, some intelligent electric-heating cooking utensils also emerge in large numbers thereupon, and it can prevent its dry combustion method by the control of control device, and is very convenient handy.But, general electric-heating cooking utensil adopts thermistor as its temperature-sensing element usually, in pot when not taking out, thermistor is sense temperature fast still, control device also can be made corresponding adjustment to heater circuit, but in the time of in lacking pot, thermistor is by the indirect temperature-sensitive of other elements, and the heating-up time is slow, also is that temperature-sensitive is insensitive, control device just can not in time be made corresponding adjustment to heater circuit, very easily burns out cooker and causes energy waste.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of respond to sensitivity, energy-conservation electric-heating cooking utensil sensing device are provided.
The technical solution of the utility model is: a kind of electric-heating cooking utensil sensing device, comprise control device, temperature-sensing element, with the peripheral spring that attaches of temperature-sensing element, with the fixedly connected tongue tube of temperature-sensing element, reach the thermistor that is connected with temperature-sensing element with the magnet of the corresponding setting of this tongue tube, described tongue tube comprises pipe and two leads, described two leads are separately fixed at the two ends of pipe, certain overlapped parallel portion is arranged and have certain clearance, lead is good magnetic conductor; Described thermistor is connected with described control device by circuit; Described tongue tube is in parallel with described thermistor.
Further, on the lever that described magnet also can place with temperature-sensing element is connected, tongue tube places the position corresponding with magnet;
Further, the position of described tongue tube and magnet is interchangeable.
The utility model is by being provided with spring in the temperature-sensing element periphery, and tongue tube is set in temperature-sensing element, accordingly, temperature-sensing element is provided with magnet outward, like this, and when pot takes out in electric-heating cooking utensil, because temperature-sensing element is provided with spring outward, it can upwards boost temperature-sensing element, and tongue tube and magnet are on the same horizontal plane, because the lead in the tongue tube is good magnetic conductor, under the effect of magnet, originally discontiguous two conductors contact because this tongue tube is in parallel with described thermistor, is equivalent to the thermistor short circuit when two conductors contact, the electric current that is way circuit increases suddenly, control device very easily detects, and sends instruction at once, disconnecting circuit.
Adopt the technical solution of the utility model, the warming method of electric-heating cooking utensil sensing device more of the prior art is more fast, sensitive, can not cause the dry combustion method of electric-heating cooking utensil, has both protected each element of electric-heating cooking utensil, has also saved the energy.

Fig. 2 is the structural representation of another embodiment of the utility model;
Fig. 3 is the structural representation of the another embodiment of the utility model.
The specific embodiment
Fig. 1 shows the structural representation of the utility model embodiment, it comprises control device, temperature-sensing element 2, with the temperature-sensing element 2 peripheral springs 4 that attach, place tongue tube 5 in the temperature-sensing element 2, be located at outer magnet 6 of temperature-sensing element 2 and the thermistor 3 that is connected with temperature-sensing element 2, thermistor 3 is connected with control device by circuit; Here, tongue tube 5 is in parallel with thermistor 3.Tongue tube 5 comprises pipe and two leads, and two leads are separately fixed at the two ends of pipe, certain overlapped parallel portion is arranged and have certain clearance, and lead is good magnetic conductor.Magnet 6 and tongue tube 5 corresponding settings.
The utility model is work like this: when the interior pot of electric-heating cooking utensil places on the temperature-sensing element 2, simultaneously temperature-sensing element 2 and the peripheral spring 4 that attaches thereof are depressed, be arranged at thermistor 3 sense temperature on the temperature-sensing element 2, and its value transferred to control device, control device is according to the program that is provided with in it, according to the input value of thermistor 3, heater circuit is adjusted accordingly; When the interior pot with electric-heating cooking utensil took out, spring 4 upwards pushed up temperature-sensing element 2, and two lead laps and magnet 6 centers in the tongue tube 5 that is arranged in the temperature-sensing element 2 are on the same horizontal line, as shown in Figure 1.Here, magnet 6 promptly refers to specifically that with tongue tube 5 corresponding settings the lead active force in 6 pairs of tongue tubes of magnet 5 is enough little, makes it be unlikely to contact when temperature-sensing element 2 is depressed by interior pot; And after spring 4 was with tongue tube 5 jack-up, magnet 6 was enough near with the conductor spacing in the tongue tube 5, made the lead active force in 6 pairs of tongue tubes of magnet 5 big as far as possible, and two leads can be contacted.
Because magnet 6 is fixed; after spring 4 is with tongue tube 5 jack-up; two lead laps and magnet 6 centers in the tongue tube 5 are on the same horizontal line; because two leads in the tongue tube 5 are good magnetic conductor; under the effect of magnet 6; two leads contact with each other; because tongue tube 5 is in parallel with thermistor 3, like this, promptly be equivalent to thermistor 3 short circuits again; the electric current of heater circuit increases suddenly; control device is given an order after detecting at once, and heater circuit is disconnected; prevent the electric-heating cooking utensil dry combustion method, protect the electric elements in it.In time disconnecting circuit has also been saved the energy.This warming method is more than temperature-sensitive is in time fast indirectly from other device by thermistor 3.
As shown in Figure 2, the utility model also can be about to the tongue tube 5 position exchange with magnet 6 magnet 6 and be fixed in the temperature-sensing element 2, and tongue tube 5 is placed on the position corresponding with magnet 6, can realize goal of the invention equally.
As shown in Figure 3, the utility model also can be realized goal of the invention by a lever 7 is set on temperature-sensing element 2: the other end that magnet 6 is fixed on lever 7, tongue tube 5 is located on the position corresponding with magnet 6, when interior pot is not depressed temperature-sensing element 2, two lead laps in magnet 6 centers and the tongue tube 5 are on the same horizontal line, since the active force of 6 pairs of tongue tube 5 inside conductors of magnet, the closing of polygon, make thermistor 3 short circuits, control device disconnects heater circuit; After interior pot is put into, temperature-sensing element 2 is depressed, that end that lever 7 is connected with temperature-sensing element 2 is depressed simultaneously, the magnet 6 of the other end is upwards pushed away, promptly left tongue tube 5 certain distances, the lead in the tongue tube 5 has broken away from the constraint of magnet 6 active forces, promptly can disconnect, control device is promptly opened heater circuit after detecting by thermistor 3.Said structure also can be realized goal of the invention, and, owing to the use of lever 7, magnet 6 can be drawn out to the position of any needs, to save the assembling space of electric-heating cooking utensil.Here, the position of magnet 6 and tongue tube 5 can exchange equally.
