Abstract
The utility model relates to an energy-saving electric cooker with interruptable power supply, belonging to the field of cooking preparative technique. Through automatic power off for a plurality of minutes when the electric cooker boils, sufficient water uptake time is for rice. The time for making meal is not effected to reach a purpose of saving power. The utility model is composed of a time circuit, a temperature detecting circuit and a switch circuit. Connected relation is that the time circuit is connected with a switch for cooking porridge. The time circuit is also connected with the temperature detecting circuit. The temperature detecting circuit and the time circuit are both connected with the switch circuit. The switch in the switch circuit is connected in series in a heating plate return circuit. The switch is the switch circuit is controlled by the temperature detecting circuit. The temperature detecting circuit also controls the working state of the time circuit. Temperature detecting circuit the time circuit is controlled by the switch for cooking the porridge. The power of the control circuit is controlled by a magnetic steel switch. Because the utility model adopts the control circuit with a function of interruptable power supply, the power and water can be saved and the phenomenon of overflow is prevented. The power saving rate of the utility model can reach about 35%.
Description
Technical field
The utility model belongs to cooking preparing technical field, is specifically related to a kind of energy-saving electric rice pot with intermittent power supply function, and international Patent classificating number is: A47J 27/00.
Background technology
The electric cooker energy-saving circuit is of a great variety, and most power saving rates all refer to the power saving rate in certain operating time, is not the power saving rate of the omnidistance work of electric cooker, control heating plate power is also arranged and has increased power-on time; Above-mentioned electric cooker is to be in power supply state when work all the time, and heating plate is in heated condition always, and boiling time is longer in the pot; As you know, rice is made meal or congee need certain temperature and enough absorbent times, common electric cooker is in order to allow rice that enough absorbent times are arranged, will suitably add some water, to prolong inevitably the heating time of electric cooker like this, thereby not only wasted electric energy and wasted water again, and be easy to generate excessive.
Summary of the invention
Goal of the invention of the present utility model provide a kind of when boiling can short supply interruption have a kind of energy-saving electric rice pot intermittent power supply function, that do not produce the pot phenomenon of overflowing with intermittent power supply function.
The utility model is by cutting off the power supply a few minutes automatically in the electric cooker boiling, allow rice that sufficient absorbent time is arranged, not influencing the purpose that the required time of cooking reaches saves energy again.
The utility model electronic circuit is made up of time circuit, temperature sensing circuit, switching circuit, its annexation is that time circuit connects the switch of cooking congee, also be connected with temperature sensing circuit, temperature sensing circuit all is connected with switching circuit with time circuit, and the switch series in the switching circuit is connected in the heating plate loop;
Described switching circuit is controlled by temperature sensing circuit, and temperature sensing circuit is the operating state of control time circuit also, the cooked congee control of switch of time circuit;
The power supply of described electronic circuit is subjected to the control of magnet steel switch.
Electronic circuit of the present utility model also is applicable to all kinds of electric rice cookers.
The course of work of the present utility model is: seethe with excitement in pot, when temperature sensing circuit detects the temperature value of setting when (as 95 ℃), the switching circuit action, stop this moment the heating plate power supply, simultaneously, time circuit picks up counting, about 5 minutes of timing, time circuit control switch circuit, heating plate obtain electricity work again, cut off the power supply up to the magnet steel switch; When cooking congee break time circuit power, heating plate is subjected to the temperature sensing circuit control intermittent power supply economic electricity of cooking congee, and is difficult for producing excessive phenomenon.
The utility model is owing to adopt and to have the electronic circuit of intermittent power supply function, so have saves energy and water, prevent to produce the good effect of excessive phenomenon, power saving rate of the present utility model can reach about 35%.

Fig. 2 is the electrical schematic diagram of the utility model embodiment.
Embodiment
The utility model is realized intermittent power supply by following circuit, reaches purpose of energy saving:
As shown in Figure 2, resistance R
1And capacitor C
1, triode BG
1Base stage, diode D
1Anodal continuous, resistance R
2With triode BG
1Collector electrode links to each other, triode BG
1Emitter and voltage-stabiliser tube CW
1Negative pole links to each other, voltage-stabiliser tube CW
1The anodal control utmost point that connects unidirectional controllable silicon S CR, the anode of controllable silicon SCR connects resistance R
3, R
3Connect relay J coil and diode D
2Anodal; Resistance R
4One end connects diode D
2Positive pole, the other end and temperature detect switch (TDS) K
2With diode D
1Negative pole links to each other, and the relay J normally opened contact is connected on heating plate P and temperature limit switch K
3Between (temperature limit switch K
3Be the control switch of electric cooker magnet steel);
Temperature detect switch (TDS) K under the normal temperature
2Closure, the relay J coil has electric current to flow through, the normally opened contact closure, heating plate P gets electric heating, seethes with excitement temperature detect switch (TDS) K in pot
2Disconnect, relay J coil losing electricity, heating plate P stop heating, at this moment because of diode D
1Negative pole uprises current potential, so by resistance R
1And capacitor C
1, triode BG
1With voltage-stabiliser tube CW
1Start working about 5 minutes capacitor C Deng the time circuit of forming
1Voltage raise, impel triode BG
1Conducting is so electric current is through resistance R
2, triode BG
1, voltage-stabiliser tube CW
1Make unidirectional controllable silicon S CR conducting, the relay J coil gets electric, and heating plate P reheats, and cuts off up to the electric cooker general supply; When cooking congee, the K switch of will cooking congee
1Disconnect, time circuit is not because of having power supply station to lose the timing effect, and heating plate P is by temperature detect switch (TDS) K
2The control intermittent power supply.
