It should be noted that the driving control module may be integrated on one printed circuit board, may be integrated on a plurality of printed circuit boards, or may be integrated in the form of a driving control box.
The driving control module is electrically connected with the first cooking electric appliance module, the second cooking electric appliance module and the refrigerator module respectively.
Referring to fig. 3, the driving circuit power distribution method of the integrated kitchen appliance of the present embodiment includes:
According to the electricity utilization condition of the integrated kitchen appliance, the maximum input power P max of the integrated kitchen appliance is defined.
Wherein, the maximum input power P max is defined according to the electricity consumption condition of the integrated kitchen appliance; for example, in china, a common household power outlet, rated at 220V, with a maximum allowable current of 10A, has a maximum allowable power of 2200W, and based on the electricity consumption condition, the maximum input power P max should be defined as 2200W; for another example, in the united states, a household power outlet should be designed according to a voltage of 125V and its fusing current of 15A, it can be seen that the maximum power allowed by the power outlet is 1875W, and based on the power consumption condition, the maximum input power P max should be defined as 1875W; it will be appreciated that in other countries and regions, the maximum input power P max of the integrated kitchen appliance should be adaptively adjusted according to the local electricity consumption conditions, and in particular, the definition of the maximum input power P max may be made before leaving the factory according to the country and region of intended sales.
The driving control module regulates and controls the first input power P 1 of the first cooking appliance module, the second input power P 2 of the second cooking appliance module and the third input power P 3 of the refrigerator module in real time to limit the sum of the first input power P 1, the second input power P 2 and the third input power P 3 to be not more than the maximum input power P max.
Specifically, when the first cooking appliance module operates: the first input power P 1 is a fixed value, or the first input power P 1 is regarded as a fixed value.
The first cooking electric appliance module is a microwave oven module, when the relay sub-module is in an on state, the first cooking electric appliance module is fixed to operate with first input power P 1, and when the relay sub-module is in an off state, the power of the first cooking electric appliance module is 0; the average output power (namely the first output power P out1) of the first cooking appliance module in a period of time can be regulated and controlled by regulating and controlling the on-off time of the relay sub-module; the first output power P out1 of the first cooking appliance module can be adjusted according to the input signal of the user interaction sub-module, for example, when the first output power P out1 is set to 700W, the relay sub-module is always in an on state; when the first output power P out1 is set to be 500W, the relay submodule is switched on for 24 seconds and then is switched off for 6 seconds, and the relay submodule reciprocates; when the first output power P out1 is set to be 350W, the relay submodule is switched on for 15s and then switched off for 15s, and the relay submodule reciprocates; when the first output power P out1 is set to be 200W, the relay submodule is switched on for 12 seconds and then switched off for 18 seconds, and the relay submodule reciprocates; when the first output power P out1 is set to be 100W, the relay submodule is switched on for 5 seconds and then switched off for 25 seconds, and the relay submodule reciprocates; when the relay sub-module is always in the on state, it is obvious that the first input power P 1 is a fixed value, and when the relay sub-module is turned on and off in a gap, although the first output power P out1 is different, the first input power P 1 is fixed during the on time, so the first input power P 1 should be regarded as a fixed value no matter what value the first output power P out1 is to be set to, and the first cooking appliance module is operated (refer to a situation that the relay sub-module is always on or the gap is on for a period of time).
The third input power P 3 of the refrigerator module is a fixed value or is regarded as a fixed value.
When the first cooking electric appliance module and the second cooking electric appliance module run simultaneously: the driving control module limits the second input power P 2 of the second cooking appliance module so that the sum of the first input power P 1, the second input power P 2 and the third input power P 3 is not greater than the maximum input power P max.
In this way, the operation power of the first cooking appliance module, the second cooking appliance module and the refrigerator module can be coordinated and controlled.
More specifically, the first input power P 1 of the first cooking appliance module is 800W to 1600W, or the first input power P 1 of the first cooking appliance module is regarded as 800W to 1600W; when the first cooking electric appliance module and the second cooking electric appliance module run simultaneously: the driving control module limits the second input power P 2 of the second cooking appliance module to 350W-1150W (limiting the set value of the user interaction sub-module or limiting the switching duty ratio of the power switching device sub-module can be realized); and, the sum of the first input power P 1 and the second input power P 2 is not more than 2000W; for example, when the first input power P 1 of the first cooking appliance module is/is regarded as 1200W, the second input power P 2 of the second cooking appliance module is limited to 750W, and the third input power P 3 of the refrigerator module, the illumination lamp of the first cooking appliance module, the turntable motor of the first cooking appliance module, the main control sub-module and the user interaction sub-module are all power required for operation, so that the input power of the whole integrated kitchen appliance is just not more than 2200W.
Further specifically, a power switch device sub-module is integrated on the drive control module, and the power switch device sub-module is electrically connected with the second cooking electric appliance module; the main control sub-module can control the switching duty ratio of the power switching device sub-module, and further control the second input power P 2 of the second cooking appliance module.
It can be understood that the power switch device sub-module at least comprises a power switch device (such as an insulated gate bipolar transistor, IGBT), and the main control sub-module controls the power switch device sub-module through a PWM signal output by the PWM output pin to adjust a switching duty ratio of the power switch device sub-module, thereby controlling the second input power P 2 of the second cooking appliance module; if the PWM output pin of the main control sub-module can directly drive the power switch device, the PWM output pin of the main control sub-module is directly connected with the control electrode of the power switch device; if the PWM output pin of the main control sub-module is insufficient to directly drive the power switch device, the power switch device sub-module further includes a driving circuit (for example, a boost driving circuit with S8050 as a core), and the PWM output pin of the main control sub-module is connected to the control end of the driving circuit, so as to control the power switch device through the driving circuit.
According to the driving circuit of the integrated kitchen appliance and the power distribution method thereof, the first input power P 1 of the first cooking appliance module, the second input power P 2 of the second cooking appliance module and the third input power P 3 of the refrigerator module can be regulated and controlled in real time, so that the sum of the first input power P 1, the second input power P 2 and the third input power P 3 is limited to be not more than the maximum input power P max, the integration degree of the kitchen appliance is higher, the power can be reasonably distributed for high-power electric appliances such as the first cooking appliance module, the second cooking appliance module and the refrigerator module, the power supply overcurrent is avoided, and the integrated kitchen appliance can be powered by using common commercial power.
