Description

Automatic watering grill pan

Technical field：

The present invention relates to electrical equipment for use in kitchen, specifically one kind can be widely used in places such as family, dining room and hotels Energy automatic watering and be automatically performed the automatic watering grill pan of food cooking process, its many kinds such as including automatic watering electric cooker Electrical equipment, in order to illustrate conveniently, all illustrated by taking automatic watering electric cooker as an example below automatic watering grill pan operation principle and its He.

Background technology：

Electrical equipment for use in kitchen existing market is even more so for grill pan also without the electrical equipment of energy automatic watering, till now also Grill pan without energy automatic watering.Most representational in automatic watering grill pan should be automatic watering electric cooker, and it makes It is most complicated with most extensive, technology.In order to clearly state our technology, below for electric cooker as example Ming Benfa It is bright.

Electric cooker has had the history of more than 70 years, is initially a kind of kitchen that MIT invents at the end of the forties Electrical equipment, was exactly at that time a pot for being capable of electrified regulation.A pot is put on electric heater, employment look at and add when cooking rice Heat, meal is obtained when good and manually powered off, and this electric heater and log do not have essential distinction in control, due to that cannot solve always certainly Dynamic outage problem, thus into a concept pot.

The mid-50 is arrived, there is further improvement in Toshiba on the basis of Mitsubishi this concept pot, Solve the problems, such as that electric cooker is automatically powered off.Their way has been added one " water timer " in outer the covering of electric cooker, former Because being hot above lid when reason is electric rice cooker heated, the small water box that a certain capacity is just designed on pot cover are pressed in power supply Above switch.During as rice, after a certain amount of water is added in small water box, power switch is just depressed by weight and closed, and is connect Energization source begins to warm up, and pot heating after heating, the water in small container gradually evaporates, and 50 minutes or so few when the water in small water box When having arrived predetermined amount, water box are just upspring by power switch after the overall weight of water box is reduced, and are also just automatically powered off, and this is most The original external force automatic power supply switch of early electric cooker.I had never expected that this technically slight progress has triggered huge market price Value, across year with regard to sales volume hundreds of thousands platform, to the latter stage fifties, the family of Japanese half has had this electric cooker.

The mid-1960s are arrived, Toshiba has carried out very many improvement to electric cooker again, and wherein temperature control is One temperature controller of metal contact is mounted with using the outer pot bottom in electric cooker, operation principle is different metal conductor Hot bending curvature after high-temperature heating is different.After electric cooker work, by the electric current normal heating of the controller, when rice is carried out When kettle temperature is increased to more than 100 degree afterwards, the temperature of the different hard contact of controller also to more than 100 degree, then not The contact point of power source connected with metal just there occurs separation, and the temperature controller is just automatically powered off, and electric cooker just stopped heating, work as temperature Two kinds of metals contact again when degree drops to less than 100 degree, begin to warm up again.The appearance of temperature controller, realizes for the first time Basic thermostatic control during rice cooking, the control of electric cooker is further automated.

After the seventies, electric cooker technology further develops, and 103 degree of soft magnet steel has been invented according to " Curie-point temperature principle " Automatic temperature controller, makes electric cooker stride forward the field of safety cooker.Control principle is to be placed on electric cooker with one block of soft magnet steel The upper end of the outer pot central temperature controller of bottom, after user presses electric cooker hand switch to be started, below the temperature controller Permanent-magnet steel contact raises and is connected with the soft magnet steel switch contact of temperature controller upper end and switched on power, and rice is cooked rear electric cooker Internal temperature is raised quickly, soft on the temperature controller of electric cooker outer pot when electric cooker bottom temp is to 103 degree Magnet steel temperature also reaches 103 degree, and soft magnet steel will lose magnetism automatically in 103 degree of Curie point, lose magnetism Magnet steel will never again connect electricity with following permanent-magnet steel contact because self gravitation and elastic force are disconnected after being automatically separated Source, realizes the reliable power-off of electric cooker, and safety problem is also solved while electric cooker auto-control is realized.

After the mid-80, the miniaturization of the microprocessor driven by computer technology has also been applied to electric cooker by dress On, realize the precise control to electric cooker so that electric cooker can arbitrarily be carried out in heating process different power heating and On/off control, realize the functional diversities of electric cooker.So far most of families are still using this inching button Ordinary electric rice cooker, be characterized in that valency is low, convenient, practical.The appearance of microprocessor causes to realize electric cooker follows one's bent Computer heating control, realize multifunction.

Last century Mo, with the continuous improvement that people are required life, occur in that Electromagnetic Heating electric cooker, abbreviation IH electricity meals Pot.This electric cooker this occur from Japan after pass to South Korea, pass to China again afterwards.It is truly realized can 360 degree substantially without The rice of the internal pot at dead angle is heated so that rice in pot can thermally equivalent and expansion, solve conventional electric cooker Interior rice gives birth to ripe, soft or hard uneven problem.

At the beginning of 21 century, it has further been found that after rice is cooked between 103 degree to 106 degree, the mouthfeel of the grain of rice is preferably, first Preceding IH electric cookers do not reach the optimal brew temperatures of rice because of interior pot entirety brew temperatures, so people are just pressure cooker function Be incorporated into IH electric cookers, IH electric pressures were then occurred in that in recent years.IH electric pressures, the temperature in pot is with pressure Power and raise, be just easy to make temperature in electric cooker to reach the optimal brew temperatures of optimal rice, the cooking quality of such rice Have been improved again.

After the degree that IH electric pressures have accomplished " perfect electric cooker " substantially, electric cooker technology is just relative to be stabilized, This several years electric cookers are mainly towards the high-end competition of pot courage and the intelligent direction of electric cooker makes an effort, but simultaneously also causes Electric cooker has sold for ten thousand yuan so that many high-end pot courage electric cookers from ordinary consumer courage increasingly away from.Besides the intelligence of electric cooker Can change remote control, many electric cookers go with the tide with high-grade pot courage mutually arrange in pairs or groups be electric cooker intelligent concept, have electric cooker APP remote controls, working reservation are cooked, function magnanimity etc., and these electric cookers can be accomplished, or even some famous electric cooker product Board publicity says that the electric cooker of oneself not only can intellectual remote controlling, moreover it is possible to cooks hundred kinds of rice, have thousand kinds of cooking methods.Why is actual conditions Sample, after these electric cookers are bought back home, if rice is done in the APP remote controls reservation of consumer's electric cooker, on 7 points of morning Class must steep rice before going out, and find that rice has peculiar smell to be difficult to eat when waiting at 7 points in evening to be had a meal after returning, and have to abandon later Remote reserved this function of cooking.There is this result because family's indoor temperature is in more than 20 to 30 degree, kettle temperature is higher In 30 to 40 degree left and right, rice steeped in pot after ten hours can spontaneous fermentation, and have after rice qualitative change slag, fermentation after steeping long Peculiar smell, the rice so made is that the grain of rice is shapeless, does not have elasticity certainly, and rice has peculiar smell and is difficult to swallow, and causes product work( The meaning of intelligent remote reservation control electric cooker actually can be just rejected with the disengaging of practical use, because this and product are declared The function actual effect of biography is not inconsistent, and therefore online resentment sound is a piece of for user, have impact on the reputation of intelligent electric rice cooker.

That also has a talk about above-mentioned some brand promotions can do hundreds of rice problem, and many consumers buy back this electricity After pot for cooking rice, it is seen that two to four on thick function declaration book and pot courage inwall delimited for different rice it is different Meal, congee add water line and feel more headache, and rough waterline this for most people is really difficult to cook the rice of suitable taste, Even if certain once do once in a while it is good after also not necessarily remember, and the intelligence shown off with electric cooker and multipotency concept are not yet Symbol, such as truly can boil 100 kinds of rice, presumably be have 100 kinds of different water feeding methods and amount of water, and this only has 2 waterlines, other 98 kinds of rice what ifThe electric cooker that many intelligence concept electric cookers can cook everybody but become not necessarily everybody can use Electric cooker, we will say that electric cooker can not become it " retarded " while " intelligence " is emphasized.

Plus quasi- water and rice can be carried out be associated with very much really, just as cook to put suitable salt it is just nice, proverb Road：One (just) salt in cook's hand.For being cooked with electric cooker, even same rice, just harvest new rice and become Amount of water after old rice is also different；Plus the congee that different water is made, it is thick, dilute certainly also different, if cook rice add it is inaccurate Water, what pot also can not do best rice, and this explanation electric cooker cooks rice, and amount of water standard is no may also to be weighed than pot courage class Will！

Please all do the objective three elements of rice looking at electric cooker：Heat, add water, the pot courage (shelves of electric cooker It is secondary).The heating of electric cooker has been realized in the accurate of computer and automatically controls, and can well realize the heating schedule of rice, just Do not speak more；The class of present electric cooker is very high, and pot courage is also near the level for reaching the peak of perfection, then improved space is not It is very big；Add water is that a problem is also a problem being missed.Because as the saying goes " not mixing like water and fire ", added water always on electrical equipment Exactly individual many people dare the thing for not wanting to be bold enough to do.

The invention allows for it is a kind of using above-mentioned automatic watering grill pan make rice method, it is characterised in that including with Lower step：

Step 1：Automatic watering and intensification impregnation stage, have arrived subscription time or user have pressed function key and opened in electric cooker During beginning work, rice species, quantity and the rice taste selected according to user, automatic watering electric cooker first carry out automatic watering, Amount of water stops adding water after having arrived specified quantity.The water of electric cooker is now added to be typically environment temperature water, temperature is at 0 degree to 40 Between degree, rice can directly be started to cook or first soaked with environment temperature water with the environment temperature water being added in container Bubble, if in order to the good water temperature of the cooking effect of rice it is too low can also opening electric heater water temperature is properly increased, while heat while Soaked, this method is, using the infusion method that heats up stage by stage, exactly to start electric heater heating, in immersion stage by stage water Temperature is progressively heated at 50 degree or so, and time of whole immersion can be usually chosen in 30 minutes or so within 2 hours, so Water can be made to be entered into inside the grain of rice through the cellulose on grain of rice surface after being soaked to rice；

Step 2：Constant temperature impregnation stage, after heating up and soaking 30 minutes by the rice of step one, this step is continuously opened again Dynamic electric heater heating makes water temperature stop heating when being increased to 60 degree or 70 degree, afterwards when water temperature correspondence drops to 50 or 60 degree again Water temperature heating to 60 degree or 70 degree is maintained water temperature between 50 degree to 70 by secondary startup heater, and we are referred to as constant temperature immersion, warp Test constant temperature immersion water temperature range suggestion to be maintained between 50 degree to 60 degree, the time is the constant temperature for carrying out 5 minutes to 20 minutes Immersion, it is proposed that constant temperature is immersed in 10 minutes or so, makes also suction moisture inside the grain of rice by after the immersion of such constant temperature, has Beneficial to the starch aquation inside the grain of rice, maltose is first converted into；

Step 3：It is rapidly heated the stage, after constant temperature impregnation stage terminates, starts the high-power heating of electric heater, strives for Water is boiled in shortest time, being rapidly heated, it is foster that grain of rice epidermin rapid aging can be made to be enhanced to pinning grain of rice inside Divide and be not lost in, this stage is rapidly heated to the time seethed with excitement between 3 minutes to 15 minutes, and The faster the better, generally at 6-10 points Clock, this stage terminates after water boiling；

Step 4：Gelatinization is boiled the stage, and gelatinization is substantially exactly the meaning of curing, is put into by after the water boiling that is rapidly heated In this stage, high-power heating and continuous a period of time is originally still first kept, allow kettle temperature highest, make the battalion such as sugar in the grain of rice Foster material is separated out to greatest extent, the glucose for making the maltose reconvert adult's physical efficiency inside the grain of rice directly absorb, such rice Meal has sweet fragrance, and by (usually 10 minutes) after the high-power heating of 5-20 minutes, electric heater can progressively be changed to middle work( Rate is heated or low-power heating or change heating, is reheated after high-power heating about 20-30 minutes；With the change being best suitable for The power for changing is heated to adapt to the cooking feature of the grain of rice, and rice is cooked in the case where moisture suitably evaporation is kept, and the gelatinization is boiled Boiling phases-time is generally at 30 to 50 minutes；Changed power can be arbitrarily adjusted in practical operation, can temporally be reached or pot Bottom temperature reaches to stop heating.

Step 5：Cook rice over a slow fire the stage, just stop heating after the stage is boiled in gelatinization, this stage is carried out with the waste heat of electric cooker Stewing system, can so make the outside evaporation capacity of steam in pot tail off, and the grain of rice is all cured with gentle steam more than waste heat in pot, if The heating being continued for can be cooked juice inside the grain of rice come with make moisture evaporation inside the grain of rice out, broken the grain of rice Bad being hardened too early can not cure completely on the contrary, boils in a covered pot over a slow fire the time processed between 5 minutes to 20 minutes, generally at 10 minutes or so.If Boil in a covered pot over a slow fire overlong time kettle temperature processed and be less than 100 degree, it is possible to start low-power heating device and heated, kettle temperature is reached Stop heating after 100 degree again, intermittent-heating is repeated and maintains stewing system；

Step 6：Rice shaping stage, after rice boils in a covered pot over a slow fire curing completely, because the inside and outside of the grain of rice has unnecessary moisture Mutual adhesion is easy for, in order that the separate disengaging of the grain of rice, just starts high-power short time heating, the outer unnecessary water of the grain of rice Point to evaporate and be dried treatment come the surface to the grain of rice and increase grain of rice hardness and intensity, by the so dried grain of rice just Maintain that preferable shape is non-breakable and nutrient outflow, make rice good-looking, nice and nutritious, the big work(of rice shaping stage Rate heating is usual at 1-5 minutes or so, generally at 2 minutes or so, as long as cooking bottom temperature must just stop heating to 103 degree, To prevent from being sticking；This step terminates rear whole rice cooking and finishes, and controller sends the well-done prompting of rice；

Step 7：Heat preservation, if be not removed after rice is cooked or by insulation, when kettle temperature reduction To Heat preservation can be carried out during uniform temperature, generally when kettle temperature drops to 60 degree, just start electric heater small-power and break Continuous to be heated to 85 degree, holding temperature is between 60 degree to 85 degree.Suggestion keeps the holding temperature in pot at 75 degree to 80 degree.

It is however emphasized that explanation, more than cook 7 steps of method of rice according to electric cooker functional requirement is different and class not Changed with that can have appropriate choice or order.

The present invention can effectively improve the mouthfeel of made rice, with reliable operation, user relative to prior art The significant advantage such as just.
