Detailed description of the invention
Embodiment 1
With reference to Fig. 1
Can the electric cooking pot of transfer power automatically, comprise a pot body, interior pot and pot cover, pot body is provided with the heater of pot in heating; Heater is in parallel with the indicator lamp LAMP of instruction electric cooking pot duty, and indicator lamp LAMP is in series with divider resistance R1.
Heater to be connected with the control device of the second operating power work after reaching preset temperature with the first operating power work before reaching preset temperature with making heater, control device comprises the first temperature switch K1 and diode D1, and the first temperature switch K1 is in parallel with diode D1; Second operating power is less than the first operating power.
It is in parallel that heater comprises the first heating plate 11 and the second heating plate 12, first heating plate 11 and the second heating plate 12.
First temperature switch K1 is connected with single-pole double-throw switch (SPDT) K3, and single-pole double-throw switch (SPDT) K3 is optionally communicated with the first temperature switch K1 and the first heating plate 11, or is communicated with the first temperature switch K1 and the second heating plate 12.
Diode D1 one end is connected with the first temperature switch K1, and the other end of diode D1 is not connected moved end with one of them of single-pole double-throw switch (SPDT) K3.
As shown in Figure 1, the not moved end of connection first heating plate 11 of diode D1 and single-pole double-throw switch (SPDT) K3 connects.If when single-pole double-throw switch (SPDT) K3 selects connection the first heating plate 11, the second heating plate 12 is in off state.When the temperature of the first heating plate does not reach design temperature (boiling temperature as water), electric current flows through the first temperature switch K1 and the first heating plate 11, and now, electric current all-wave is passed through, and the first heating plate 11 is in the first operating power duty.When the temperature of the first heating plate reaches design temperature, the first temperature switch K1 disconnects, and electric current flows through diode D1 and the first heating plate 11, now electric current only half-wave pass through, the first heating plate 11 is in half-power duty, maintain boiling.In the process, only heat by the 1 in electric cooking pot before water boiling, its heating is comparatively slow, belongs to slow and stewes.
If during single-pole double-throw switch (SPDT) K3 selection connection the second heating plate 12, diode D1 formation first heating plate of connecting with the first heating plate 11 combines, first temperature switch K1 connect the second heating plate 12 formed second heating plate combination, first heating plate combination and the second heating plate combination parallel connection.Half-wave is by the first heating plate combination all the time for electric current, and the first heating plate 11 is in the second operating power duty all the time.When the second heating plate 12 does not reach design temperature, electric current flows through the second heating plate combination, and the second heating plate 12 is in the first operating power duty.When the second heating plate 12 reaches design temperature (as water boiling temperature), the first temperature switch K1 disconnects, and now the second heating plate heater 12 does not work, and only the first heating plate heater 11 is in the second operating power duty, maintains boiling.In the process, jointly heated in electric cooking pot before water boiling by the first heating plate 11 and the second heating plate, its heating is comparatively rapid, belongs to fast and stewes.The closing position of single-pole double-throw switch (SPDT) K3 can be controlled by external knob, to select stew soon or stew pattern slowly, and be no matter fast stew or slow stew pattern under, after water boiling, its first heating plate 11 by the second operating power maintains boiling, its firepower is less than the heating period, to save electric energy.
Can expect, the not moved end of connection second heating plate 12 of diode D1 and single-pole double-throw switch (SPDT) K3 connects also can realize above-mentioned work.
Described electric cooking pot also has the second temperature switch K2, and heater is connected with the second temperature switch K2.
Technical conceive of the present invention is: when heater does not reach preset temperature, and the first temperature switch K1 is in closure state, and the first temperature switch K1 is communicated with power supply and heater, and heater is in the first operating power duty.After heater reaches preset temperature, the first temperature switch K1 disconnects, and heater is connected with power supply by diode D1, and only have half-wave current to flow through heater, heater carries out the second operating power duty; Namely after the temperature of heater reaches preset temperature, heater is automatically converted to the second operating power duty, maintains boiling, prevents food materials in pot to overflow pot.In the process, jointly heated in electric cooking pot before water boiling by the first heating plate 11 and the second heating plate 12, its heating is comparatively rapid, belongs to fast and stewes.The closing position of single-pole double-throw switch (SPDT) K3 can be controlled by external knob, to select stew soon or stew pattern slowly, and be no matter fast stew or slow stew pattern under, after water boiling, its first heating plate 11 by the second operating power maintains boiling, its firepower is less than the heating period, to save electric energy.
The present invention has the advantage that automatically can change power, anti-Spill stopping pan after reaching preset temperature.
Embodiment two
With reference to Fig. 2
The present embodiment is with the difference part of embodiment one: the two ends of diode D1 are connected with the two ends of the first temperature switch K1 respectively.All the other structures are all identical.
As shown in Figure 2, diode D1 forms diode-switch combination with the first temperature switch K1 is directly in parallel, diode-switch combination Series Sheet double-pole double throw switch K3, two of single-pole double-throw switch (SPDT) K3 not moved end connect the first heating plate 11 and the second heating plate 12 respectively, first heating plate 11 and the parallel connection of the second heating plate 12 form heating plate combination, heating plate combined serial second temperature switch K2.
No matter no matter single-pole double-throw switch (SPDT) K3 selects connection first heating plate 11 or the second heating plate 12, its course of work is as described below: when not reached design temperature by the temperature of heating plate selected, first temperature switch K1 closes, electric current all-wave flows through this by the heating plate selected, and heating plate is in the first operating power duty.When being reached design temperature by the temperature of heating plate selected, the first temperature switch K1 disconnects, and electric current only half-wave flows through this by the heating plate selected, and heating plate is in the second operating power duty.During the second operating power duty, the temperature of heating plate declines, and realizes the automatic conversion of temperature, anti-Spill stopping pan, better can keep the nutrition of food materials.In the process, jointly heated in electric cooking pot before water boiling by the first heating plate 11 and the second heating plate 12, its heating is comparatively rapid, belongs to fast and stewes.The closing position of single-pole double-throw switch (SPDT) K3 can be controlled by external knob, to select stew soon or stew pattern slowly, and be no matter fast stew or slow stew pattern under, after water boiling, its first heating plate 11 by the second operating power maintains boiling, its firepower is less than the heating period, to save electric energy.
Content described in this description embodiment is only enumerating the way of realization of inventive concept; protection scope of the present invention should not be regarded as being only limitted to the concrete form that embodiment is stated, protection scope of the present invention also and conceive the equivalent technologies means that can expect according to the present invention in those skilled in the art.
