Description of drawings
Fig. 1 is first kind of embodiment of the present invention.
Fig. 2 is second kind of embodiment of the present invention.
The specific embodiment
Embodiment 1
With reference to Fig. 1
Automatically the electric cooking pot of transfer power comprises a pot body, interior pot and pot cover, and the pot body is provided with the heater of pot in the heating; Heater is parallelly connected with the indicator lamp LAMP of indication electric cooking pot duty, and indicator lamp LAMP is in series with divider resistance R1.
Heater with can make heater before reaching preset temperature with the first operating power work and after reaching preset temperature the control device with the second operating power work be connected; Control device comprises the first temperature switch K1 and diode D1, and the first temperature switch K1 is parallelly connected with diode D1; Second operating power is less than first operating power.
Heater comprises first heating plate 11 and second heating plate, 12, the first heating plates 11 and 12 parallel connections of second heating plate.
The first temperature switch K1 is connected with single-pole double-throw switch (SPDT) K3, and single-pole double-throw switch (SPDT) K3 optionally is communicated with the first temperature switch K1 and first heating plate 11, perhaps is communicated with the first temperature switch K1 and 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 the moved end with one of them of single-pole double-throw switch (SPDT) K3.
As shown in Figure 1, diode D1 connects with the not moved end that is connected first heating plate 11 of single-pole double-throw switch (SPDT) K3.When if single-pole double-throw switch (SPDT) K3 select to connect first heating plate 11, second heating plate 12 is in off state.When the temperature of first heating plate does not reach design temperature (like the boiling temperature of water), electric current the flow through first temperature switch K1 and first heating plate 11, at this moment, the electric current all-wave is passed through, and first heating plate 11 is in the first operating power duty.When the temperature of first heating plate reached design temperature, the first temperature switch K1 broke off, electric current flow through the diode D1 and first heating plate 11, this moment electric current only half-wave pass through, first heating plate 11 is in the half-power duty, keeps boiling.In this process, only to heat before the water boiling in the electric cooking pot by the 1, its heating is comparatively slow, belongs to stewed slowly.
When if single-pole double-throw switch (SPDT) K3 selects to connect second heating plate 12; Diode D1 connects with first heating plate 11 and forms the combination of first heating plate; The first temperature switch K1, second heating plate 12 of connecting forms the combination of second heating plate, and the combination of first heating plate is parallelly connected with the combination of second heating plate.Half-wave is through the combination of first heating plate all the time for electric current, and first heating plate 11 is in the second operating power duty all the time.When second heating plate 12 does not reach design temperature, flow through second heating plate combination of electric current, second heating plate 12 is in the first operating power duty.When second heating plate 12 reached design temperature (like the water boiling temperature), the first temperature switch K1 broke off, and this moment, the second heating plate heater 12 was not worked, and only the first heating plate heater 11 is in the second operating power duty, keeps boiling.In this process, to heat jointly by first heating plate 11 and second heating plate before the water boiling in the electric cooking pot, its heating is comparatively rapid, belongs to fast and stewes.Can be through the closing position of external knob control single-pole double-throw switch (SPDT) K3; To select the fast pattern of stewing or stew slowly; And no matter be to stew or stewing slowly under the pattern fast, after the water boiling, its first heating plate 11 by second operating power is kept boiling; Its firepower is less than the heating period, with saves energy.
Can expect that diode D1 connects with the not moved end that is connected second heating plate 12 of single-pole double-throw switch (SPDT) K3 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 did not reach preset temperature, the first temperature switch K1 was 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 reached preset temperature, the first temperature switch K1 broke off, and heater is connected with power supply through diode D1, and the half-wave current heater of flowing through is only arranged, and heater carries out the second operating power duty; Promptly after the temperature of heater reached preset temperature, heater was automatically converted to the second operating power duty, keeps boiling, prevented the excessive pot of pot interior food materials.In this process, to heat jointly by first heating plate 11 and second heating plate 12 before the water boiling in the electric cooking pot, its heating is comparatively rapid, belongs to fast and stewes.Can be through the closing position of external knob control single-pole double-throw switch (SPDT) K3; To select the fast pattern of stewing or stew slowly; And no matter be to stew or stewing slowly under the pattern fast, after the water boiling, its first heating plate 11 by second operating power is kept boiling; Its firepower is less than the heating period, with saves energy.
The present invention has the advantage that can after reaching preset temperature, change power, anti-Spill stopping pan automatically.
Embodiment two
With reference to Fig. 2
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 and directly parallelly connected formation diode-switch combination of the first temperature switch K1; Diode-switch combination Series Sheet double-pole double throw switch K3; Two of single-pole double-throw switch (SPDT) K3 not the moved end connect first heating plate 11 and second heating plate, 12, the first heating plates 11 and the second heating plate 12 parallel connections formation heating plates combination, the heating plate combined serial second temperature switch K2 respectively.
No matter no matter single-pole double-throw switch (SPDT) K3 selects to connect first heating plate 11 still is second heating plate 12; Its course of work is described below: when the temperature of selecteed heating plate does not reach design temperature; The first temperature switch K1 is closed; Electric current all-wave this selecteed heating plate of flowing through, heating plate is in the first operating power duty.When the temperature of selecteed heating plate reached design temperature, the first temperature switch K1 broke off, and electric current is half-wave this selecteed heating plate of flowing through only, and heating plate is in the second operating power duty.During the second operating power duty, the temperature of heating plate descends, and realizes the automatic conversion of temperature, anti-Spill stopping pan, the nutrition that can better keep food materials.In this process, to heat jointly by first heating plate 11 and second heating plate 12 before the water boiling in the electric cooking pot, its heating is comparatively rapid, belongs to fast and stewes.Can be through the closing position of external knob control single-pole double-throw switch (SPDT) K3; To select the fast pattern of stewing or stew slowly; And no matter be to stew or stewing slowly under the pattern fast, after the water boiling, its first heating plate 11 by second operating power is kept boiling; Its firepower is less than the heating period, with saves energy.
The described content of this specification embodiment only is enumerating the way of realization of inventive concept; Protection scope of the present invention should not be regarded as and only limit to the concrete form that embodiment states, protection scope of the present invention also reach in those skilled in the art conceive according to the present invention the equivalent technologies means that can expect.
