Background technology Chinese Patent Application No. 201310303201.4 entitled " a kind of cooking time control method " provides A kind of method controlling cooking time according to the change of foodstuff surface color.I.e. when the service condition of known chromonic materials, permissible By corresponding termination color as end condition, by detection foodstuff surface color and the difference that terminates between color whether Less than setting value, decide whether to terminate barbecue.The shortcoming and defect of various control methods before the method overcoming, it is possible to straight See, control cooking time exactly.When the deficiency of the method is chromonic materials service condition in not knowing food ingredients, as roasting System with the addition of the various meats of dispensing when buying, just cannot arrange termination color, the method the most just cannot be applied to control roasting Time processed.Chinese Patent Application No. 2014100099267 proposes " a kind of cannot know chromonic materials kind and consumption situation Lower control cooking time simple and quick method ", cooking process is divided into forward and backward two sections, leading portion use timing control, timing time according to The kind of food and weight are tabled look-up acquisition, back segment using at leading portion to foodstuff surface color samples the data obtained as search condition, Retrieving foodstuff surface complexion changed path data data during the baking prestored, it is the most identical with search condition that application is obtained The optimal baking color in complexion changed path or the time of its correspondence carry out color control to back segment or timing controls.Although solving The problem controlling cooking time under chromonic materials service condition cannot be known, but, due to enforcement and the control quality of the method Foodstuff surface complexion changed path data when depending on baking, this is for having no ability to do the equipment manufacturer meaning of Computer Simulation Early stage to need to do great many of experiments, especially when food has the flavoring agent of color development effect possibly together with sugar, soy sauce etc. simultaneously, early stage Workload can be the biggest.There occurs change if there is new chromonic materials or original chromonic materials performance, all can force and set More substantial experiment is done by standby manufacturer, and upgrades the product having been sold out.With the exception of this, Chinese Patent Application No. 2014100099267 color control method provided are that the similarity investigating the instant color of foodstuff surface and preset color is No more than threshold value, it is low that threshold value is arranged, and control accuracy is poor, the height that threshold value is arranged, and sample frequency is not high enough, it is possible to has missed Control point, causes out of control.Meanwhile, the height that threshold value is arranged, it is desirable to the service condition of chromonic materials is enough refined, makes early stage create The workload of data base strengthens further, makes amount of calculation strengthen the most further, and sample frequency high arithmetic speed will be sufficiently fast, this All device hardware is proposed requirements at the higher level a bit.

Summary of the invention

The technical problem to be solved in the present invention is to provide one and is independent of foodstuff surface complexion changed path data during baking, and energy The method accurately, reliably controlling cooking time in the case of cannot knowing chromonic materials kind and consumption.The technology of the present invention Scheme is: a kind of cooking time control method, according to the foodstuff surface color obtained by sampling with expectation baking color in color Distance S in space controls cooking time.

When described cooking time terminates at above-mentioned distance S=0, or increment S >=0 of above-mentioned distance S, or above-mentioned distance S Increment S >=0, and the increment (S) of increment S > 0 time.

There is advantages that applicable various chromonic materials service condition, including use simultaneously multiple cannot Know the situation of chromonic materials；Eliminate Database and data update, reduce product development cost.What raising controlled can By property and precision.

Detailed description of the invention

The invention will be further described with embodiment below in conjunction with the accompanying drawings.

Embodiment 1

Fig. 1 and Fig. 2 gives a kind of baking box applying the present invention and controls program.This program presses control mode cooking process Being divided into two stages, leading portion is that timing controls the stage, and latter end is that color controls the stage.

The present embodiment selects RGB color, employing to be arranged on above cooking cavity, the cromogram of output RGB data form As foodstuff surface color is sampled by sensor, and it is converted into the statistical number of mean value formation or other forms through statistical computation According to.Conversion equation set can be applied to carry out the corresponding relation changed owing to shades of colour space exists, so, it would however also be possible to employ its His color space and sensor.This baking box has a weighing device, and before dispatching from the factory various foods under different processing modes with right The expectation baking color editor answered tabulates and is stored in data storage, before entering subprogram, first to gather relevant to food Information do unloaded detection, then select processing mode, processing mode is divided into: heats, roast, baking etc., have selected processing After mode is " barbecue ", calls and start to perform barbecue subprogram shown in Fig. 2.Generally by the effect to food, can be barbecue point For ripening and two stages of colouring, can control stage and color in the present embodiment respectively to control the stage corresponding with timing, The colouring stage can also be divided into two sections, wherein leading portion uses timing to control, and latter end is color control.During the timing that timing controls Between and the baking condition of each cook stages table look-up according to food species and weight and obtain.After entering color control subprogram, it is desirable to Baking color generates according to processing mode and food species automatic look-up table, it is desirable to baking color can also be specified by user.Face In the step 1004 of color control subprogram and step 1009, S is not distance, but distance square, this is because reduce calculate The needs of amount, and owing to need not be concerned about apart from the most how many, it is only necessary to investigate the relative pass between two distances or its increment System, at this moment with use distance be equivalent.Control to be spacing based on instant color Yu desired color due to the present embodiment color From minima, certainly exist, even and if miss minima, it is also possible to time point behind is as starting to control a little.So, Compared with color control method based on similarity, there is higher control accuracy and reliability.

Embodiment 2

Seeing Fig. 1 and Fig. 3, compared with previous embodiment, difference essentially consists in the present embodiment subprogram in satisfied distance S Increment S >=0 time, the increment (S) of increment S to be investigated > 0 no.This is because, baking should allow, the most not Midway can be got rid of and open the situation generation of cooking chamber door, open door and the temperature of cooking chamber and food can be made to decline, food table Face complexion changed slows down or stops, and continues baking and form the change of distance S as shown in Figure 4 with stationary point after again shutting door Curve, meets increment S=0 on a of stationary point, but is unsatisfactory for the increment (S) of increment S > 0, only meet S=at b point 0 and (S) > 0, if it addition, because certain reason misses and has minima b point, baking also can also be made to terminate at it After time point c because after b point, on all multi-point samplings including c point, all meet S > 0 and (S) > 0, therefore, Not only can get rid of midway and open the interference that cooking chamber door causes, and a little will not cause out of control because missing a certain starting to control, from And improve the reliability of control.Remaining not described part, with embodiment 1.

It is pointed out that every equivalent flow process utilizing description of the invention and accompanying drawing content to be done converts, or identical The different expression of essence implication, and directly or indirectly it is used in other relevant technical fields, all patents in the present invention are protected In the range of protecting.
