[0049] Referring to FIG3 , the power distribution method for the driving circuit of the integrated kitchen appliance of this embodiment includes:

[0050] Define the maximum input power of integrated kitchen appliances based on their power usage conditions .

[0051] Among them, the maximum input power It is defined according to the power conditions of integrated kitchen appliances. For example, in mainland China, the rated voltage of an ordinary household power socket is 220V and the maximum allowable current is 10A. It can be seen that the maximum power allowed by the power socket is 2200W. Based on this power condition, the maximum input power should be It is defined as 2200W; for example, in the United States, household power sockets should be designed according to 125V voltage, and their fusing current is 15A. It can be seen that the maximum power allowed by the power socket is 1875W. Based on the power conditions, the maximum input power should be It is defined as 1875W; it is understandable that in other countries and regions, the maximum input power of integrated kitchen appliances should be adjusted according to local power conditions. Adaptive adjustments can be made based on the country and region of intended sales, and the maximum input power can be set before shipment. Definition of .

[0052] The driving control module adjusts the first input power of the first cooking appliance module in real time , the second input power of the second cooking appliance module And the third input power of the refrigerator module , to limit the first input power , the second input power And the third input power The sum is not greater than the maximum input power .

[0053] Specifically, when the first cooking appliance module is in operation: the first input power is a fixed value, or the first input power Considered as a fixed value.

[0054] The first cooking appliance module is a microwave oven module. When the relay submodule is in the on state, the first cooking appliance module is fixed at the first input power. When the relay submodule is in the off state, the power of the first cooking appliance module is 0; by adjusting the on and off time of the relay submodule, the average output power of the first cooking appliance module over a period of time (i.e., the first output power) can be adjusted. ); a first output power of the first cooking appliance module It can be adjusted according to the input signal of the user interaction submodule, for example, setting the first output power When the output power is 700W, the relay submodule is always in the on state; set the first output power When the output power is 500W, the relay module is connected for 24 seconds and then disconnected for 6 seconds, and so on. Set the first output power When the power is 350W, the relay module is connected for 15 seconds and then disconnected for 15 seconds, and so on. Set the first output power When the output power is 200W, the relay module is connected for 12 seconds and then disconnected for 18 seconds, and so on. Set the first output power When the power is 100W, the relay submodule is connected for 5s and then disconnected for 25s, and so on. When the relay submodule is always in the on state, it is obvious that the first input power is a fixed value. When the relay submodule gap is on and off, although the first output power will vary, but during the on-time, the first input power is fixed, therefore, whatever will set the first output power What value is it? When the first cooking appliance module is running (meaning that the relay submodule is always on or intermittently on for a period of time), the first input power should be Considered as a fixed value.

[0055] The third input power of the refrigerator module is or is considered to be a fixed value.

[0056] When the first cooking appliance module and the second cooking appliance module are running simultaneously, the driving control module limits the second input power of the second cooking appliance module , so that the first input power , the second input power And the third input power The sum is not greater than the maximum input power .

[0057] In this way, coordinated control of the operating power of the first cooking appliance module, the second cooking appliance module and the refrigerator module can be achieved.

[0058] More specifically, the first input power of the first cooking appliance module 800W~1600W, or the first input power of the first cooking appliance module Considered as 800W to 1600W; when the first cooking appliance module and the second cooking appliance module are running at the same time: the driving control module sets the second input power of the second cooking appliance module to The power supply is limited to 350W~1150W (both can be achieved by limiting the setting value of the user interaction submodule or limiting the switching duty cycle of the power switch submodule); and the first input power With the second input power The sum is not greater than 2000W; for example, when the first input power of the first cooking appliance module When the second input power of the second cooking appliance module is / is regarded as 1200W, the second input power of the second cooking appliance module Limited to 750W, plus a third input power for the refrigerator module The power required for the operation of the refrigerator module's lighting, the first cooking appliance module's lighting, the first cooking appliance module's turntable motor, the main control submodule and the user interaction submodule just makes the input power of the entire integrated kitchen appliance no more than 2200W.

[0059] More specifically, the drive control module is integrated with a power switch submodule, which is electrically connected to the second cooking appliance module; the main control submodule can control the switching duty cycle of the power switch submodule, thereby controlling the second input power of the second cooking appliance module. .

[0060] It is understood that the power switch device submodule includes at least a power switch device (such as an insulated gate bipolar transistor, IGBT), and the main control submodule controls the power switch device submodule through the PWM signal output by the PWM output pin to adjust the switching duty cycle of the power switch device submodule, thereby controlling the second input power of the second cooking appliance module. ; If the PWM output pin of the main control submodule can directly drive the power switching device, the PWM output pin of the main control submodule is directly connected to the control terminal of the power switching device; if the PWM output pin of the main control submodule is not sufficient to directly drive the power switching device, the power switching device submodule also includes a driving circuit (for example, a boost driving circuit with S8050 as the core), and the PWM output pin of the main control submodule is connected to the control end of the driving circuit to control the power switching device through the driving circuit.

[0061] The driving circuit and power distribution method of the integrated kitchen appliance of this embodiment can adjust the first input power of the first cooking appliance module in real time. , the second input power of the second cooking appliance module And the third input power of the refrigerator module , to limit the first input power , the second input power And the third input power The sum is not greater than the maximum input power This not only makes the kitchen appliances more integrated, but also can reasonably distribute power to high-power appliances such as the first cooking appliance module, the second cooking appliance module and the refrigerator module, avoiding power overcurrent. Ordinary AC power can be used to power the integrated kitchen appliances.
