The electric cooker proposed according to embodiments of the present invention and its control method are described with reference to the accompanying drawings.
First, the control method of the electric cooker proposed according to embodiments of the present invention, the embodiment of the present invention are described with reference to the accompanying drawings Control method be suitable for all temperature sensors judge boiling scheme.
Fig. 2 is the flow chart according to the control method of the electric cooker of one embodiment of the invention.It is as shown in Fig. 2, of the invention The control method of the electric cooker of embodiment includes the following steps:
S1, after electric cooker starts, control electric cooker is heated with the first mean power.
Specifically, as shown in figure 3, for the schematic diagram of the process to be worked according to the electric cooker of one embodiment of the present of invention. Wherein, P1 detects temperature curve for electric cooker bottom sensor, and P2 is water temperature curve, and P3 is examined for rice cooker upper cover temperature sensor The temperature of survey, P4 is heater heating pulse, and in pulse, height represents heater heating, low, represents heater and stops heating.Such as It was heated in Fig. 3 for 1 stage, after electric cooker starts, initial heat-up stage is heated to ensure rapidly with the first mean power It heats up.First mean power refers to mean power, and the first mean power is larger power, such as sets electric cooker heater Rated power for P, the heating Power Regulation ratio of the first mean power is H1, and the Power Regulation period of H1 can be such as 32 seconds, the tune of H1 Work(ratio can be such as 16/32.
S2, when the temperature in electric cooker reaches the first preset temperature, control electric cooker pause heating.
When being heated with the first mean power, also to consider to ensure that temperature will not be excessively high, prevent from overflowing.When in electric cooker Control electric cooker stops heating when temperature reaches the first preset temperature.Such as first preset temperature can be 87-93 DEG C, it is more excellent Ground, when the coolant-temperature gage in electric cooker reaches 90 DEG C, control electric cooker stops heating.Specifically, such as electric cooker includes temperature Sensor, temperature sensor are located on the upper lid of electric cooker, are controlled with the temperature of the temperature sensor senses of rice cooker upper cover Temperature, when the temperature of upper cover temperature sensor detection reaches 90 DEG C of corresponding water temperature, you can control electric cooker pause heating.
S3, after the first preset time, control electric cooker continues to heat with the first mean power.
For example, such as 1 stage of stopping in Fig. 3, wherein, control electric cooker pause heats and mainly realizes two effects, one It act as cutting down the thermal inertia that heater in above-mentioned 1 stage of heating (particularly electric hot tray) long-time heating tape comes, prevents continuous Heating causes spilling;Another act as the delay of sensing of equilibrium temperature sensor, such as causes the temperature sensor on upper lid The temperature of sensing is more nearly true water temperature.After the first preset time is heated in pause, control electric cooker is average with first Power continues to heat, as heated the part in 2 stages to be heated with 1 stage equal-wattage of heating in Fig. 3, so that on water temperature continues It rises.Wherein, the first preset time can be configured as the case may be.
S4, when the temperature in electric cooker reaches the second preset temperature, control electric cooker is added with the second mean power Heat is to prevent from overflowing.
Specifically, control electric cooker continues to heat with the first mean power, when reaching the second preset temperature, control Electric cooker is converted to be heated with the second mean power.Second preset temperature is more than the first preset temperature, for example, second is default Temperature can be 93-97 DEG C, more preferably, such as when water level is increased to 95 DEG C since 90 DEG C of the first preset temperature, more than The temperature sensor senses temperature covered is punctual, i.e., when upper cover temperature sensor senses temperature reaches 95 DEG C of corresponding water temperature, Control electric cooker is converted to be heated with the second mean power, wherein, the Power Regulation ratio of the second mean power is less than first and is averaged The Power Regulation ratio of power, the Power Regulation period of the second mean power are more than the Power Regulation period of the first mean power, such as the second average work( The Power Regulation ratio of rate can be H2, and the Power Regulation period of H2 can be such as 120 seconds, and Power Regulation ratio can be such as 20/120, i.e. H2< H1, but 120 seconds Power Regulation periods of H2>32 seconds Power Regulation periods of H1.Wherein, by taking Power Regulation was than cycle set 90-180 seconds as an example, the The Power Regulation of two mean powers than optimized scope 10-30 seconds service time.
Such as the latter half such as 2 stage of heating in Fig. 3, with 20/120 Power Regulation than the second mean power heated When, i.e., it is heated within continuous 20 seconds and then stops within 100 seconds completing a cycle, so recycled.So heating in continuous 20 seconds stops again Only, water temperature curve slowly rises, such as DEG C than shallower from 95 DEG C to 100, in addition, according to this Power Regulation than it is second average Power is heated, even if laser heating 20 seconds, but the dwell time of a cycle also long enough, it is possible to ensure even Continuous heating will not overflow after 20 seconds.
S5, when the temperature in electric cooker reaches boiling equilibrium temperature point, control electric cooker is carried out with third mean power It heats to maintain to boil.
Specifically, when electric cooker is controlled to be heated with the second mean power, water temperature steadily slowly rises, because in electricity After stopping for 1 stage in pause heating period such as Fig. 3 in rice cooker, the entire heating amount of electric cooker slowly slows down, while temperature The temperature-sensitive delay of sensor has obtained abundant abatement in entire heating process, when electric cooker has continuous a large amount of steam to emerge, It is generally acknowledged that having boiled, temperature sensor can detect an equilibrium temperature, this temperature may be considered boiling equilibrium temperature Point, when the temperature in electric cooker reaches boiling equilibrium temperature point, control electric cooker is heated to tie up with third mean power Hold boiling, such as the maintenance boiling stage in Fig. 3, with the Power Regulation of a H3 than power carry out heating and maintain boiling, H3 can be with It is such as 3/32.
In addition, environment temperature can also influence the boiling temperature of electric cooker, such as in highlands, boiling is not achieved in electric cooker Temperature.In one embodiment of the invention, during liquid boiling in electric cooker, the upper cover temperature sensor detection of electric cooker Temperature-resistantization when temperature can be set as equilibrium temperature point, and the equilibrium temperature point that boils can be equilibrium temperature point with it is default The difference of number temperature spot, wherein, temperature-resistantization is it is considered that being basically unchanged.For example, predetermined number temperature spot is 3-4 temperature AD values are spent, that is, represents, will normally boil in electric cooker, the equilibrium temperature point of upper cover temperature sensor detection shifts to an earlier date 3-4 The migration temperature spot i.e. boiling equilibrium temperature point that a temperature AD values are heated as electric cooker with the second mean power, so as to protect When card cannot reach such as 100 DEG C of normal boiling temperature in certain areas such as highlands, ensure the temperature control to electric cooker, it can It will not be overflowed again with reaching the boiling temperature of local environment.
S6, after the second preset time, control electric cooker stops heating.
After control electric cooker boils the second preset time with third mean power for example with 3/32 Power Regulation than maintenance, Electric cooker is controlled to close.Second preset time can be 3-10 minutes, such as maintain after boiling 5 minutes, and control electric cooker closes It closes, completes work.Wherein, the mouthfeel that the second preset time can for example cook according to the effect that electric cooker reaches suitably is prolonged It is long.
In conclusion the control method of electric cooker according to embodiments of the present invention, by the way that electric cooker is controlled to be rapidly heated Later, pause heating is to cut down the lag of heating thermal inertia and temperature detection, and then continues to be heated to the first mean power Second preset temperature is then heated with the second mean power that Power Regulation is smaller and the Power Regulation period is longer, and is reaching boiling Boiling is maintained when rising equilibrium temperature point, temperature can be caused slowly steadily to increase, so as to ensure that electric cooker can reach boiling temperature It will not be overflowed while spending, temperature control is more accurate.In addition, the equilibrium temperature preset in advance number temperature that temperature sensor is detected Point, can be to avoid the temperature control inaccuracy caused by the influence of environment as boiling equilibrium temperature point.
A kind of electric cooker that embodiment proposes according to another aspect of the present invention is described with reference to the accompanying drawings.
Fig. 4 is the block diagram according to the electric cooker of one embodiment of the present of invention.As shown in figure 4, the electricity of the embodiment of the present invention Rice cooker includes temperature sensor 10, timer 20, heater 30 and controller 40.
After electric cooker starts, controller 40 controls heater 30 to be heated with the first mean power, in electric cooker Temperature when reaching the first preset temperature, controller 40 controls the pause heating of heater 30, and after the first preset time, control When heater 30 processed continues to heat with the first mean power and the temperature in electric cooker reaches the second preset temperature, control When heater 30 is heated with the second mean power and the temperature in electric cooker reaches boiling equilibrium temperature point, control Heater 30 is heated with third mean power to maintain to boil, and after the second preset time, and control heater 30 stops Only heat.Wherein, the second preset temperature is more than the first preset temperature, and the Power Regulation ratio of the second mean power is less than the first mean power Power Regulation ratio, Power Regulation period of the second mean power is more than the Power Regulation period of the first mean power.
Specifically, as shown in figure 3, for the schematic diagram of the process to be worked according to the electric cooker of one embodiment of the present of invention. As heated in Fig. 3 for 1 stage, after electric cooker starts, initial heat-up stage is heated quick to ensure with the first mean power It heats up on ground.First mean power refers to mean power, and the first mean power is larger power, such as sets electric cooker bottom Heating Power Regulation ratio for H1, the Power Regulation period of H1 can be such as 32 seconds, and the Power Regulation ratio of H1 can be such as 16/32.
When being heated with the first mean power, also to consider to ensure that temperature will not be excessively high, prevent from overflowing.When in electric cooker When temperature reaches the first preset temperature, controller 40 controls the pause heating of heater 30.Such as first preset temperature can be 87- 93 DEG C, more preferably, when the temperature in electric cooker reaches 90 DEG C, controller 40 controls the pause heating of heater 30.Specifically, example It is located at such as temperature sensor 10 on the upper lid of electric cooker, i.e., the temperature sensed with the temperature sensor of rice cooker upper cover 10 is controlled Temperature, when the temperature that temperature sensor 10 detects reaches 90 DEG C of corresponding water temperature, controller 40 controls electric cooker pause heating.Such as figure 1 stage of stopping in 3, wherein, controller 40 controls electric cooker pause heating is main to realize two effects, and one act as cutting down The thermal inertia in above-mentioned 1 stage of heating, prevents laser heating from causing to overflow;Another act as the temperature-sensitive of equilibrium temperature sensor 10 Lag, such as the temperature that the temperature sensor 10 on upper lid senses is caused to be more nearly true water temperature.In pause heating first After preset time, controller 40 control heater 30 continue to heat with the first mean power, as heated in Fig. 3 in 2 stages with The part heated with 1 stage equal-wattage of heating, so that water temperature continues to rise.
When continue heating reach the second preset temperature when, controller 40 control heater 30 be converted to the second mean power It is heated.Second preset temperature is more than the first preset temperature, for example, the second preset temperature can be 93-97 DEG C, more preferably, Such as when water level is increased to 95 DEG C since 90 DEG C, specifically, subject to 10 temperature sensor of temperature sensor covered above When, i.e., when 10 temperature sensor of the temperature sensor of upper cover reaches 95 DEG C of corresponding water temperature, controller 40 controls heater 30 to convert To be heated with the second mean power, wherein, Power Regulation ratio of the Power Regulation than being less than the first mean power of the second mean power, the The Power Regulation period of two mean powers is more than the Power Regulation period of the first mean power.In one particular embodiment of the present invention, example Power Regulation ratio such as the second mean power can be H2, and the Power Regulation period of H2 can be such as 120 seconds, and Power Regulation ratio can be for example 20/120, i.e. H2<H1, but 120 seconds Power Regulation periods of H2>32 seconds Power Regulation periods of H1.Wherein, 90- is set than the period with Power Regulation For 180 seconds, the Power Regulation of the second mean power than optimized scope 10-30 seconds service time.
Such as the latter half such as 2 stage of heating in Fig. 3, with 20/120 Power Regulation than the second mean power heated When, i.e., it is heated within continuous 20 seconds and then stops within 100 seconds completing a cycle, so recycled.Heating in continuous 20 seconds stops again, water Warm curve slowly rises, such as DEG C than shallower from 95 DEG C to 100, in addition, according to this Power Regulation than the second mean power Heated, even if laser heating 20 seconds, but the dwell time of a cycle also long enough, it is possible to ensure continuously plus Heat will not overflow after 20 seconds.
When controller 40 controls heater 30 to be heated with the second mean power, water temperature steadily slowly rises, because After 1 stage of stopping during electric cooker suspends heating such as Fig. 3, the entire heating amount of electric cooker slowly slows down, while temperature The temperature-sensitive delay of sensor 10 has obtained abundant abatement in entire heating process, when electric cooker has continuous a large amount of steam to emerge When, it is considered that it has boiled, temperature sensor 10 can detect an equilibrium temperature, this temperature may be considered boiling balance Temperature spot, when the temperature in electric cooker reaches boiling equilibrium temperature point, controller 40 controls heater 30 to be averaged work(with third Rate is heated to maintain to boil, such as the maintenance boiling stage in Fig. 3, with the Power Regulation of one 3/32 than power heated Maintain boiling.
In addition, environment temperature can also influence the boiling temperature of electric cooker, such as in highlands, boiling is not achieved in electric cooker Temperature.In one embodiment of the invention, during liquid boiling in electric cooker, such as the temperature sensing on rice cooker upper cover Temperature during temperature-resistantization that device 10 detects can be set as equilibrium temperature point, and the equilibrium temperature point that boils can be equilibrium temperature The difference of point and predetermined number temperature spot, wherein, temperature-resistantization may be considered being basically unchanged.It for example, will be in electric cooker just Often in the case of boiling, the equilibrium temperature point that the temperature sensor 10 on upper lid detects shifts to an earlier date 3-4 temperature AD value as electric cooker With the migration temperature spot of the second mean power heating i.e. boiling equilibrium temperature point, thereby may be ensured that on certain areas such as plateau When area cannot reach such as 100 DEG C of normal boiling temperature, ensure the temperature control to electric cooker, the boiling of local environment can be reached Temperature will not overflow again.
After control electric cooker boils the second preset time with third mean power for example with 3/32 Power Regulation than maintenance, Electric cooker is controlled to close.Second preset time can be 3-10 minutes, such as maintain after boiling 5 minutes, control heater 30 Stop heating, complete work.Wherein, the second preset time can be carried out according to the mouthfeel of the effect that electric cooker reaches such as congee soup It is appropriately extended.
In conclusion electric cooker according to embodiments of the present invention, heater is controlled after being rapidly heated by controller, Pause heating to cut down the lag of heating thermal inertia and temperature detection continues that heater is controlled with the first mean power to add Heat then controls heater to be added with the second mean power that Power Regulation is smaller and the Power Regulation period is longer to the second preset temperature Heat, and boiling is maintained when reaching boiling equilibrium temperature point, temperature can be caused slowly steadily to increase, so as to ensure that electric cooker can It will not be overflowed while to reach boiling temperature, temperature control is more accurate.In addition, the equilibrium temperature that temperature sensor is detected shifts to an earlier date Predetermined number temperature spot, can be to avoid the temperature control inaccuracy caused by the influence of environment as boiling equilibrium temperature point.
