Abstract
The invention relates to a cooking method of microwave oven for defrosting and cooking frozen food. It is characterized by that it utilizes an infrared sensor to measure out the temp of frozen food surface, if the temp value is reached to the set temp value, it can cognize that the defrostation of said food is completed, and the next cooking procedure can be continuously made, the above-mentioned set temp value is 20 deg.C.
Description
Technical field
The present invention relates to micro-wave oven, particularly relate to the cooking control method of micro-wave oven.
Background technology
In general, micro-wave oven is that the microwave that utilizes magnetron to produce is penetrated into the inside of food and the heating appliances of heat food.
For make micro-wave oven to add thermal control more accurate, the facility infrared ray sensor.This infrared ray sensor is installed in a side of furnace chamber, so that accept the food radiation, the variations in temperature of perception foodstuff surface, and information is sent to the microprocessor of micro-wave oven inside, microprocessor serves as basis next step heating of decision or controlled condition with the foodstuff surface temperature that perceives thus.
As shown in Figure 1, general micro-wave oven by the rotating disk (11) of placing food, produce microwave and be transported to the magnetron (12) on interior the food of furnace chamber (10), the cooling fan (13) of cooling magnetron and infrared ray sensor (14) formation of detection food temperature by waveguide.
The micro-wave oven operational situation of above-mentioned formation is as described below.
At first, the user imports cooking instruction, and controller (omitting diagram) just drives magnetron (12).
Then, the microwave of magnetron (12) generation is transported in the furnace chamber (10) heat food by waveguide.
Simultaneously, infrared ray sensor (14) is according to the relevant temperature output voltage values of the food of monitoring, and magnitude of voltage is handled in the back input controller through a series of signal.
Controller drives magnetron (12) food is heated, until the temperature of food reaches predetermined temperature.
In addition, in order to cool off hot magnetron (12), cooling fan (13) turns round during the cooking is carried out.
Fig. 2 shows the food thawing and the gastronomical process of micro-wave oven in the past.
As shown in Figure 2, at first, the user opens the door of micro-wave oven, and food is put into furnace chamber; Afterwards by function key, just according to defrost mode (S21) beginning melting chilling food.
After thaw after a while (S22), open fire door and check frozen food whether thaw fully (S23); If food thaws fully, just begin to carry out the cooking mode of thawed foodstuff.
That is, reselect the cooking key (S24) of micro-wave oven, input cooking mode and cooking time (S25).If frozen food does not thaw fully, just the course of defrosting of repetition.
By said process, cook (S26) according to the cooking time of having set according to selected cooking mode and food weight.If reach the time (S27) of setting, finish thus to thaw and gastronomical process.Otherwise, just gastronomical process repeatedly.
As mentioned above, utilized the key that thaws earlier frozen food to be thawed in the past, confirmed the melting state of food then, and utilized the function key input time of micro-wave oven again and add thermopower and cook, and promptly be divided into and thaw and cook two stages.
And, in gastronomical process, the food state in the cooking room is confirmed, so that implement to stop heating or supplementary heating.
Therefore, when cooked the back that thaws that in the past utilized micro-wave oven to carry out food, from thawing up to the overall process of cooking food, the user almost will keep in the micro-wave oven front and can not leave, so user's time and physical demands just become a big problem.
Summary of the invention
The present invention proposes in order to address the above problem, its objective is in the time of will cooking frozen food the back that earlier frozen food thawed in the past, two stages of operation cooking key once finish again, the micro-wave oven of providing convenience for the user uninterruptedly thaws and cooking method thus.
Micro-wave oven involved in the present invention uninterruptedly thaws and cooking control method comprises: detect the frozen food surface temperature stage by infrared ray sensor; If temperature value reaches the temperature value that sets, just think to finish and thaw, continue to enter next step cooking stage then incessantly; Detected frozen food surface temperature value does not reach the temperature value that sets in the above-mentioned stage, just repeats the stage of course of defrosting.
The above-mentioned set temperature value that the present invention relates to is 20 ℃.
In addition, the present invention includes the user need not input weight, according to the time that reaches above-mentioned set temperature value, judges food weight.
And the heat time heating time in cooking stage of the present invention and power level are according to the time in the zone that thaws variable more 100%, 80% or 60% etc.
As mentioned above, micro-wave oven of the present invention uninterruptedly thaws and cooking control method, frozen food is in the past thawed shorten into a stage by the process in two stages of cooking key again after finishing, and once implements without a break to thaw and cook, for the user provides convenience.Frozen food is being thawed in the process of the cooking, the user can reduce operating time and muscle power than in the past.

The specific embodiment
Describe specific embodiments of the invention in detail referring now to accompanying drawing.
Fig. 3 is the detected foodstuff surface temperature of an infrared ray sensor of the present invention coordinate diagram.Fig. 4 is the flow chart of control method of the present invention.
Uninterruptedly thaw and to cook control procedure as described below with reference to the micro-wave oven of Fig. 3 and Fig. 4 explanation.
At first, the user opens the door of micro-wave oven, and food is put into furnace chamber, selects to thaw/cook continuous key then, carries out (S41) with the uninterrupted pattern of thawing/cook that melting chilling food begins.
Afterwards, the micro-wave oven infrared ray sensor detects the temperature (S42) on frozen food surface.
At this, owing to use infrared ray sensor, need not import food weight and also can be worth the needed time and judge weight according to reaching uniform temperature.
The required time appellation of will the thawing regional T1 that thaws cooks regional T2 with appellation heat time heating time of finishing the cooking stage of the beginning of thawing.In order to judge that whether frozen food thaws, the temperature of finishing the point of the regional T1 that thaws that thaws is set according to the value of average experiment value regulation, design temperature is represented with A ℃.
Usually, as finishing the initial point that thaws, be set at 20 ℃ with above-mentioned A ℃.
Detect the surface temperature of frozen food, judge whether the temperature of frozen food reaches the temperature of setting (A).If reached design temperature, uninterruptedly go on automatically continuously at the zone that thaws (T1) and cooking zone (T2).
But,, then continue to repeat course of defrosting if also do not reach above-mentioned design temperature.
The heat time heating time and the power level in cooking zone (T2) can change to 100%, 80% or 60% according to the zone that thaws (T1) time.
So, uninterruptedly thaw and cook control procedure according to micro-wave oven of the present invention, infrared ray sensor detects the surface temperature of frozen food, if temperature value reaches set temperature value, just thinking thaws finishes, and enters next step cooking stage incessantly continuously.
