Background technique

In recent years, kitchen cooking utensils commonly used in general households include: gas stoves, gas stoves, electronic microwave ovens, induction cookers, and the like.

The above-mentioned electronic microwave oven (MWO; Microwave Oven) mainly uses the microwave (Microwave) generated by the magnetron MGT as the main heating source to disrupt the molecular chain of the food in the cooking chamber (Cavity), and heats up the food through the frictional heat generated between food molecules. cooking.

An induction cooker is a cooking utensil that uses a heater (Heater) as the main heating source for cooking.

In order to provide multiple heating states for electronic microwave ovens, in addition to the magnetron, a heater is also arranged inside the cooking chamber.

The above-mentioned electronic microwave oven provided with a heater can selectively use the heat generated by the heater and the microwave generated by the magnetron to heat the food to be cooked.

An electronic microwave oven with a magnetron and a heater can provide multiple heating states, thereby increasing the variety of cooking.

The general structure and operation of an electric microwave oven having a heater will be described below with reference to FIG. 1 .

Fig. 1 is a structural block diagram of an electronic microwave oven with a heater in the prior art.

As shown in the figure, an electronic microwave oven with a heater in the prior art includes: a magnetron 10 for generating microwaves and a heater 20 for generating heat as a heating source, a high-voltage transformer 11, RY1 first relay 12, RY2 second relay 21, Turntable motor 30, circulation motor 40. The high-voltage transformer 11 is used to apply high-voltage power to the magnetron 10; RY1 first relay 12 controls the power supplied to the high-voltage transformer 11; RY2 second relay 21 controls the power supplied to the heater 20; the turntable motor 30 is used to rotate Turntable (not shown); Circulation motor 40 is used to start circulation fan (Convection Fan figure not shown); Circulation fan makes the hot air that produces on heater 20 circulate inside cooking chamber.

As shown in the figure, the magnetron 10 as the heating source of the electronic microwave oven, the heater 20 and the turntable motor 30 are connected in parallel to the power supply AC.

The magnetron 10 is arranged on the cavity of the electronic microwave oven, and its function is to generate microwaves to the food; the heater 20 is also arranged on the cavity, and is used to supply heat to the food.

The turntable motor 30 drives the turntable on which the food is placed to rotate, so that the microwaves generated by the magnetron 10 or the hot gas generated by the heater 20 are evenly supplied to the food.

The circulation motor 40 rotates the circulation fan to circulate the hot air generated by the heater 20 inside the cooking chamber.

The first relay 12 connected to the high-voltage transformer 11 that applies a high voltage to the magnetron 10 and the second relay 21 connected to the heater 20 are driven according to the operating signal of the system control part (not shown), and are respectively controlled to be supplied to the magnetron 10. Magnetron 10 and heater 20 power supply.

As mentioned above, the electronic microwave oven has the function of starting the operation of the magnetron 10 and the heater 20 at the same time, and the function of starting the operation of the heater 20 only. Therefore, the operator can selectively execute according to the selected cooking type.

Next, a cooking control method using a prior art heater will be described.

Fig. 2 is a schematic flowchart of a cooking control method for a cooking appliance with a heater in the prior art.

As shown in Figure 2, when the operator uses the heater to perform automatic cooking, he selects the required cooking mode stage S10;

The operator inputs a cooking start command stage S11;

Read the preset overall cooking time T1+T2 stage S12 corresponding to the automatic cooking selected by the operator;

After displaying the read overall cooking time T1+T2, drive the heater 20 while starting to calculate the first cooking time T1 stage S13;

Judging whether the first cooking time T1 stage S14 has passed;

After the above-mentioned first cooking time T1, temporarily stop the drive of the heater 20 and output a low tone signal at the same time, so that the operator can know the turning time stage S15 of the food;

The operator turns over the food in the cooking chamber after hearing the low tone signal.

After the above-mentioned bass signal is delayed for a predetermined time, the output system is driven within about 1 minute, and then the heater 20 is driven for the second cooking time T2 in stage S16.

Judging whether the second cooking time T2 stage S17 has passed;

After the second cooking time T2 elapses, the driving of the heater 20 is stopped to end the cooking process stage S18.

That is, in the conventional cooking mode using the heater, after the heater 20 is driven for the first cooking time T1, the heater 20 is driven again for the second cooking time T2 with a delay of a predetermined time by using a low-pitched signal to warn of the turning time of the food.

In the existing control method for cooking with a heater, a low tone signal is used to alarm the time for flipping food during the cooking process. At this time, if the operator does not turn over the food, the food on the heated side will be heated again.

Because the operator does not overturn the food, the electronic microwave oven of the prior art will continue to perform cooking in the remaining time, thereby causing a part of the food to be scorched and the other part to be undercooked, thereby reducing the cooking performance of the product.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the above-mentioned technologies, and provide a cooking control method for a cooking utensil with a heater that controls the remaining cooking time according to whether the food is overturned and improves the cooking performance when the heater is used for cooking.

The technical solution to solve the above-mentioned technical problems is: a cooking control method for cooking utensils with a heater. The method is carried out in the following stages: the operator first selects the cooking mode using the heater, and reads the preset value corresponding to the cooking mode selected by the operator. A fixed overall cooking time T1+T2 stage; in the above-mentioned read overall cooking time, the stage of cooking by driving the heater for the first cooking time T1; after the above-mentioned first cooking time T1, temporarily stop the drive of the heater , and the stage of outputting the bass signal; after the above-mentioned bass signal is output, it is judged whether the stage of continuously sensing the opening and closing action of the microwave oven door is sensed; Cooking time T2 is the stage of driving the heater for cooking; if the opening and closing of the microwave oven door is not sensed, the stage of driving the heater for cooking with the preset third cooking time T3.

The third cooking time T3 is equivalent to 20% to 50% of the second cooking time T2.
