Description
Technical field
The utility model relates to the electric cooker of electric cooker technical field, particularly a kind of variable power.
Background technology
Common electric pot is due to easy to use, and the feature such as simple to operate, is well received by consumers.But existing electric cooker is general only to be controlled by temperature controller, when electric cooker is when cooking, after rice boils, because inner bag moisture is less, so that inner bag temperature raises and reaches temperature limiter take-off temperature, and the power supply of temperature limiter disconnection electric heating body, avoids burning; When electric cooker needs to retain more juicy cooking task as Baoshang, pot congee etc., there is following defect: 1, need people's hand control cooking length of time; 2, when there is no manual control, if temperature controller is Automatic-reset temperature controller, during the cooking, occur burning/Automatic-reset temperature controller take-off deenergization during burnt so that inner bag excess Temperature, heated condition changes other heated condition into or stops heating from normal condition, when inner bag temperature reduces uniform temperature, Automatic-reset temperature controller resets and switches on power, and continues to enter normal heating state, so circulation, until food dryouies in inner bag; If temperature controller is hands reset type temperature controller, during the cooking, occur burning/hands reset type temperature controller take-off deenergization during burnt so that inner bag excess Temperature, heated condition changes other heated condition into or stops heating from normal condition, so that inner bag food can not continue the cooking.
Utility model content
The purpose of this utility model is to overcome the deficiency that above-mentioned prior art exists, and provides a kind of simple and reasonable for structure, can manually convert the electric cooker of the variable power of heating mode.
The purpose of this utility model is achieved in that
A kind of electric cooker of variable power, comprise control circuit and heating board, it is characterized in that: described control circuit at least includes temperature limiter, the first temperature controller, the second temperature controller, first dam diode and change-over switch, after temperature limiter and the second temperature controller are connected in parallel, connect with heating board, the first temperature controller, first dams and after diode and change-over switch are connected in parallel, is connected on one end of temperature limiter.
The purpose of this utility model can also adopt following technical measures to solve:
As a kind of scheme more specifically, described control circuit also comprises insulation indicator lamp and heat-insulating lamp dropping resistor, in parallel with the second temperature controller after insulation indicator lamp and the series connection of heat-insulating lamp dropping resistor.
Described heat-insulating lamp dropping resistor one end is also in series with the second diode.
Described control circuit also comprises burner on light and heating lamp dropping resistor, in parallel with heating board after burner on light and the series connection of heating lamp dropping resistor.
Described heating lamp dropping resistor one end is also in series with the 3rd diode.
The beneficial effects of the utility model are as follows:
(1) this kind of capable of regulating power electric cooker is by power change switch and the first temperature controller, diode combinations, can be by controlling temperature and heater power, to reach the cooking, need to retain more juicy food (as soup and congee etc.), prevent from being sticking, no longer as the electric cooker of prior art, only in moisture evaporation dry (or soon evaporation is dry), just quit work;
(2) the first temperature controller take-off temperature of this kind of capable of regulating power electric cooker is 90 degrees Celsius, when change-over switch is opened, electric cooker is first with heating with full power, make heated food reach with fast speed boiling (the approaching 100 degrees Celsius) state that approaches, when inner bag temperature reaches 90 degrees Celsius, the first temperature controller take-off, electric current is passed by through first diode that dams, heating board power is reduced by half, realize slow fire heating;
(2) this kind of capable of regulating power electric cooker also has the second temperature controller, and the operating temperature of the second temperature controller is 60 degrees Celsius, and when inner bag temperature is during at 60 degrees Celsius, the second temperature controller conducting, makes heating board energising, keeps food not cool off.
Accompanying drawing explanation
Fig. 1 is the utility model one embodiment circuit theory diagrams.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
Shown in Figure 1, a kind of electric cooker of variable power, comprise control circuit and heating board W, described control circuit includes temperature limiter t0, the first temperature controller t1, the second temperature controller t2, first dam diode D1 and change-over switch S, after temperature limiter t0 and the second temperature controller t2 are connected in parallel, connect with heating board W, the first temperature controller t1, first dams and after diode D1 and change-over switch S are connected in parallel, is connected on one end of temperature limiter t0.
Described control circuit also comprises insulation indicator lamp L2 and heat-insulating lamp dropping resistor R2, in parallel with the second temperature controller t2 after insulation indicator lamp L2 and heat-insulating lamp dropping resistor R2 series connection.
Described heat-insulating lamp dropping resistor R2 one end is also in series with the second diode D2.
Described control circuit also comprises burner on light L1 and heating lamp dropping resistor R1, in parallel with heating board W after burner on light L1 and heating lamp dropping resistor R1 series connection.
Described heating lamp dropping resistor R1 one end is also in series with the 3rd diode D3.
Wherein, the take-off temperature of the first temperature controller t1 and the second temperature controller t2 is respectively 90 ℃ and 60 ℃.The first temperature controller t1 and the second temperature controller t2 are the temperature controller that automatically resets.Temperature limiter t0 needs hand-reset.
Described control circuit also comprises fuse FU, and in Fig. 1, L end is live wire incoming end, and N end is zero line incoming end.
Its operation principle is: while making the more juicy foods of needs reservation such as soup, congee when needs, plug in, change-over switch S is made as to off-state, electric cooker starts the required food of automatic-cooking, heating board heating with full power inner bag, now, temperature limiter t0, the first temperature controller t1 and the second temperature controller t2 are all in conducting state; In gastronomical process, when glass inner bag temperature reaches 60 ℃, the second temperature controller t2 first disconnects, but does not change heated condition; Heating board W is still with heating with full power work, make glass inner bag reach fast 90 ° of C, the first temperature controller t1 action disconnects, when electric current dams diode D1 by first, the electric current that makes half is tackled by the first diode D1 that dams, heating board only has half-power heating glass inner bag, avoids moisture rapid evaporation in glass inner bag.When if long-time heating has the situation of the sticky pot of food to occur, glass inner bag surface temperature raises, temperature limiter t0 take-off, avoid continuing high-temperature heating so that be sticking, until glass inner bag surface temperature drops to 60 ℃ when following, the second temperature controller t2 automatically resets, and makes electric heat-emitting board W continue normal work, so circulation, auto-steering heat insulation work.
While not needing to retain too many moisture when cooking, plug in, change-over switch S is made as to on-state, electric cooker starts the required food of automatic-cooking, heating board heating with full power glass inner bag, when glass inner bag temperature reaches 100 ° of C, moisture is evaporated, temperature limiter t0 take-off, avoid continuing high-temperature heating so that be sticking, until glass inner bag surface temperature drops to 60 ℃ when following, the second temperature controller t2 automatically resets, and makes electric heat-emitting board W continue normal work, so circulation, auto-steering heat insulation work.
