Abstract

The invention discloses a rice cooking control method for a rice cooker. The rice cooker comprises a cooker body, an inner container, an upper cover, a heating device, a bottom temperature detector and a control device, wherein the control device comprises a main controller, a timer, a temperature storage, a time storage and a heating power storage; and the rice cooking control method for the rice cooker with the control device comprises the following steps that the main controller controls the timer to time t from zero, and compares the bottom temperature Tb detected by the bottom temperature detector with the bottom temperature B1 preset in the temperature storage; when Tb is smaller than B1, the main controller controls the heating device to heat at a power which is preset in the heating power storage and corresponds to the rice and water amount grade, otherwise, the heating device does not heat; and a cycle is repeated until the time t reaches time t1 which is preset in the time storage and corresponds to the rice and water amount grade. By the method, the cooked rice is sufficiently heated additionally, excessive steam in the rice is evaporated, and the rice fragrance of the rice is increased.

Description

A kind of control method of cooking rice over a slow fire of electric cooker

Technical field

The present invention relates to a kind of control method of cooking rice over a slow fire of electric cooker.

Background technology

[0002] the various computermatic electric cooker of selling in the market generally can carry out supplementary heating after rice boils, namely cook rice over a slow fire, and purpose is that steam unnecessary in the rice is further evaporated, to increase the fragrance of rice.Computermatic electric cooker generally reaches the temperature value of certain setting with the interior pot bottom temperature that takes up rice, such as 125 ℃, judge that rice boils.It is fairly simple that the process of cooking rice over a slow fire is then processed relatively, generally be set a regular time such as 10 minutes, a fixing interior pot temperature such as 95 ℃, a fixing heating Power Regulation such as 1/16, at a fixed time, be lower than 95 ℃ of the temperature of setting such as the interior pot temperature of actual measurement, the electric cooker heating, otherwise electric cooker does not heat.

In this control method, all be the identical control temperature of employing and heat the Power Regulation ratio for different Mi Shuiliang, and when rice boils, temperature generally all is higher than 95 ℃, therefore the most of the time does not heat in the process of cooking rice over a slow fire, especially for the rice amount, the heating wretched insufficiency of supplementary heating, cause steam residual in the rice to be back to the rice bottom by rice or along pot body inwall, make rice bottom moisture content many, the rice effect is partially soft or partially mashed, can only smell the steam flavor after the end of cooking rice over a slow fire is uncapped, and can't smell a meter fragrance.And iff being the control temperature that improves the process of cooking rice over a slow fire, then be easy to cause the rice bottom sallow phenomenon to occur because supplementary heating is excessive for the millet amount.

Summary of the invention

The technical problem to be solved in the present invention be overcome the deficiencies in the prior art and provide a kind of heat heat enough, can fully evaporate rice superfluous water steam, the electric cooker that improves rice aroma is cooked rice over a slow fire control method.

For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of control method of cooking rice over a slow fire of electric cooker, described electric cooker comprises pot body, place the cook control device of work of set control on bottom thermal detector set on the inner bag of pot in the body, loam cake, heater, pot body and pot body, control device includes master controller and is connected timer, temperature memory, time memory and the heating power memory that is connected with master controller, and the described control method of cooking rice over a slow fire that adds control device control electric cooker comprises:

The main controller controls timer timing t that starts from scratch, and the bottom temp B1 that presets in the bottom temp Tb of bottom thermal detector induction and the temperature memory compared, comparative result is as follows,

As Tb during less than B1, the main controller controls heater heats with default in the heating power memory, the power corresponding with the Mi Shuiliang grade;

Otherwise the main controller controls heater does not heat;

So circulation is until the time t that the timer meter gets reaches default, corresponding with Mi Shuiliang grade time t1 in the time memory, and the process of cooking rice over a slow fire finishes.

Further, the described rice water yield is provided with 4 grades, is preset with corresponding with 4 grades of Mi Shuiliang respectively power in the described heating power memory.

Further, the described rice water yield is provided with 4 grades, is preset with respectively the time t1 corresponding with the Mi Shuiliang grade in the described time memory.

Compared with prior art, the present invention with respect to the beneficial effect of prior art is:

The present invention is by being distinguished different Mi Shuiliang, different heating powers and heat time heating time are set, for the rice that boils provides enough and inexcessive heats, fully evaporate unnecessary steam in the rice, make the rice bottom form the film of thin layer, increase the rice fragrance of rice, and sallow phenomenon can not occur.

Description of drawings

The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.

Fig. 1 is the structural representation of embodiment electric cooker;

Fig. 2 is the theory diagram of embodiment electric rice pot controller;

Fig. 3 is cook the stage control flow chart of cooking rice over a slow fire in the process of embodiment electric cooker;

Fig. 4 to Fig. 6 is related data default in embodiment electric cooker power and the time memory.

The specific embodiment

As shown in Figure 1 and Figure 2, the present embodiment electric cooker includes pot body 1, inner bag 2, loam cake 3, to the heater 4 of inner bag heating, be arranged at the bottom thermal detector 5 of pot body bottom and be arranged at and be used for the cook control device 6 of work of control on pot body, control device 6 includes master controller 7 and is connected timer 8, temperature memory 9, time memory 10 and the heating power memory 11 that is connected with master controller.The output of bottom thermal detector 5 is connected with the input of master controller 7, and the output of master controller 7 is electrically connected with heater 4.

Show such as Fig. 4, be preset with the time t1 corresponding with each Mi Shuiliang grade in the time memory 10.

Show such as Fig. 5, be preset with bottom temp B1 in the temperature memory 9.

Show such as Fig. 6, be preset with the power P corresponding with each Mi Shuiliang grade 1 in the heating power memory 11.

The rated power of heater 4 is fixed in the present embodiment, and the actual heating power P1 of stages is not quite similar, and recently adjusts with different Power Regulations, i.e. the ratio of heat time heating time and total cycle time in heating cycle.The following heating power of mentioning also recently replaces with Power Regulation accordingly.Mi Shuiliang judges that in the process of cooking the method for judgement has detailed introduction in the prior art, will not describe in detail here, and Mi Shuiliang is provided with 4 grades in the present embodiment, is respectively the 1st grade, the 2nd grade, the 3rd grade and the 4th grade.
