Embodiment 1

[0021] like figure 1 A control method for an automatic heating microwave oven is shown, the automatic heating microwave oven includes a heating unit, the automatic heating microwave oven is provided with a heating cavity, the heating unit heats the food in the heating cavity, and the automatic heating microwave oven It also includes a temperature measurement unit and a control unit, the heating unit and the temperature measurement unit are respectively connected to the control unit; when the heating unit starts, the temperature measurement unit regularly measures the ambient temperature in the heating cavity and transmits it to the control unit, so The control unit calculates the temperature change value at this test time point and the previous test time point, and when the difference between the temperature change values ​​at two adjacent test time points is greater than or equal to a preset threshold, the control unit controls the heating unit Turn off the heating and the he...

Embodiment 2

[0043] A preferred embodiment is that the interval time n is 5-15s.

[0044] In the process of experimenting with the range of interval time, it is found that when the selected heating unit materials and varieties are different, or even the structure of the heating chamber is different, the temperature rise and change speed is different, but the overall scheme principle is the same , so the interval time needs to be adjusted according to the specific microwave oven; it is also found in the experiment that when the sensitivity of the selected temperature measurement unit is different, the interval time needs to be adjusted accordingly. Experimental results show that when the interval time n is 5-15s, the automatic heating microwave oven can judge the completion of heating more sensitively and accurately.

[0045] Further, the interval time n is 10s, and the threshold is 8.8-9.

[0046] When the threshold is 8.8-9, the food has been heated to 100°C. Considering that the user do...

Embodiment 3

[0049] On the basis of Example 2, the heating method of the heating unit is: heating with rated power until the heating unit stops heating. With this technical solution, since the control unit judges the heating stop time according to the threshold value, the heating unit can work according to the rated power, shorten the heating time, improve the heating efficiency, and there is no need to worry about the food being overheated.

[0050] Further, the temperature measuring unit is arranged in the heating chamber, the temperature measuring unit includes a thermistor and a metal probe, the thermistor is connected to the metal probe, and the thermistor is connected to the control unit. Since the temperature measurement unit measures the ambient temperature of the inner tank of the heating chamber, the technical solution adopts a thermistor, which is cheap and easy to obtain, and does not need to consider the temperature of the food container and the size of the food. Impact.

Abstract

The invention relates to a control method of an automatic heating microwave oven. The automatic heating microwave oven comprises a heating unit and a heating chamber, wherein the heating unit is used for heating food in the heating chamber, a temperature measurement unit and a control unit are further comprised, the heating unit and the temperature measurement unit are connected with the control unit, when the heating unit starts, environment temperature in the heating chamber is regularly detected by the temperature measurement unit and is further transmitted to the control unit, a temperature change value of a test time point and a previous test time point is calculated by the control unit, when the temperature change value of the two adjacent test time points is greater than or equal to a preset threshold, the heating unit is controlled by the control unit for stopping heating, heating is accomplished, and the threshold is preset. The method is advantaged in that when the temperature change value of the two adjacent test time points is greater than or equal to the preset threshold, heating is accomplished, temperature interference of the heating chamber is avoided, and hand-operated heating time adjustment taking regard of water content and weight of the food is not needed.

Description

technical field [0001] The invention relates to a microwave oven, in particular to a control method for automatically heating the microwave oven. Background technique [0002] In many modern families and companies, people use microwave ovens to reheat a meal or packaged food. However, existing microwave ovens generally rely on the user to choose the heating time to reheat. In actual use, many people do not know how long it will take to reheat a certain food, which makes it difficult for people to use microwave ovens, which are not energy-saving and environmentally friendly, and the effect is not satisfactory. [0003] At present, there are mainly two methods of reheating technology for microwave ovens in the market. 1. The user manually selects the heating time and starts the heating. 2. The user selects the food type and portion, and starts heating. Both of the above two methods need to rely on the user's own judgment and selection of parameters for heating. When users f...
