[0002] With the acceleration of the modern life rhythm and the limitation of living space, people's demand for multi-functional appliances is increasing day by day. Traditional induction cookers, microwave ovens, and refrigerators are all independent units, occupying a relatively large space and unable to be used normally in special situations such as power outages. Therefore, the emergence of integrated appliance all-in-ones, through highly integrated design, facilitates the integration of multiple functions, thus facilitating people's use and at the same time improving the space utilization rate within the building unit.

And the setting of this integrated kitchen appliance has the advantages of high space utilization rate, low cost, and excellent energy consumption control; however, since this appliance only controls each module through the main circuit board, it does not have the corresponding emergency power supply capability for the access and disconnection of the mains electricity.

[0053] Step 4: The main control module 12 in the control module 1 determines whether the microwave oven is working properly. If yes, the main control module 12 in the control module 1 controls the relay 21 to actuate, causing the second electrical appliance module 5, i.e., the refrigerator, to lose power. If no, the second electrical appliance module 5 operates normally.

[0054] Through the coordinated setting of the control method, the convenience and stability of electrical appliance use can be effectively improved, and the reliability of the emergency function of the electrical appliance can be enhanced.

[0055] Embodiment 1:

[0056] The system is powered on, and the refrigerator module, i.e., the second electrical appliance module 5, is connected to the mains power supply, with an input power of P2.

[0057] When the first electrical appliance module 4 is operating, the first current detection module of the first electrical appliance module 4 detects the input current of the first electrical appliance module 4 to obtain the input power P1 of the first electrical appliance module 4. When the third electrical appliance module 6 is operating, the second current detection module of the third electrical appliance module 6 detects the input current of the third electrical appliance module 6 to obtain the input power P3 of the third electrical appliance module 6. When each electrical appliance module starts to operate, the control module 1 determines that P1 + P2 + P3 < P MAX , when the condition is met, the first electrical appliance module 4 and the third electrical appliance module 6 can be normally started by the mains power supply. If the control module 1 determines that P1 + P2 + P3 > P MAX , in the startup sequence, the later-started electrical appliance module is powered by the energy storage module 3.

[0058] For example: 1. When the refrigerator module, i.e., the second electrical appliance module 5 and the first electrical appliance module 4 are powered by the mains power supply, and the total power is greater than P MAX when starting the third electrical appliance module 6, the control module 1 controls the RL3 of the switching module 2 to control the third electrical appliance module 6 to be powered by the energy storage module 3;

[0059] 2. When the refrigerator module, i.e., the second electrical appliance module 5 and the third electrical appliance module 6 are powered by the mains power supply, and the total power is greater than P MAX when starting the first electrical appliance module 4, the control module 1 controls the RL1 of the switching module 2 to control the first electrical appliance module 4 to be powered by the energy storage module 3;

[0060] 3. When the refrigerator module, i.e., the second electrical appliance module 5 is operating, and the total power is greater than P MAX when starting the third electrical appliance module 6, the control module 1 controls the RL3 of the switching module 2 to control the third electrical appliance module 6 to be powered by the energy storage module 3;

[0061] When the first electrical appliance module 4 and the refrigerator module, i.e., the second electrical appliance module 5 are operating, the refrigerator module, i.e., the second electrical appliance module 5 will automatically lose power.

[0062] Embodiment 2:

[0063] The working conditions of the first electrical module 4 and the refrigerator. The microwave control relay of the first electrical module 4, i.e., relay 41, is set as a single-pole double-throw relay, with one end normally open and the other end normally closed. The microwave transformer / frequency converter is connected to the normally open end, and the refrigerator power supply is connected to the normally closed end of relay 41 within the first electrical module 4. When the microwave function is started, relay 41 within the first electrical module 4 is energized, the microwave starts, and the refrigerator power supply is automatically disconnected; when the microwave function stops, relay 41 within the first electrical module 4 will not immediately disconnect, and it needs to delay at least 3 minutes to disconnect before the refrigerator power supply can be restored.

[0064] Embodiment 3:

[0065] The input power P1 of the first electrical module 4 ≤ 1500W, the input power P3 of the third electrical module 6 ≤ 2200W, and the input power P2 of the refrigerator module, i.e., the second electrical module 5 ≤ 500W.

[0066] When the power grid is powered off, the switching module 2 automatically switches through RL2 of relay 21 to be powered by the energy storage module 3 for the refrigerator module, i.e., the second electrical module 5, and at the same time powers the control module 1 through any one of the switches RL1, RL2, RL3 of relay 21.

[0067] Generally, the stored electricity Q of the energy storage module 3 is small, usually 1KWh, that is, 1 degree of electricity.

[0068] The output power P storage of the energy storage module 3 is at most 2200W. When powered by the energy storage module 3, the control module 1 controls that only the refrigerator module, i.e., the second electrical module 5 and the first electrical module 4 are allowed to work, and the third electrical module 6 is not allowed to work. At the same time, the first electrical module 4 must satisfy P1*t ≤ 1 / 2Q, where t is the set maximum working time of the first electrical module 4.

[0069] Embodiment 4:

[0070] After the integrated electrical appliance is connected to the mains, the refrigerator module, i.e., the second electrical module 5 is powered on, and the energy storage module 3 automatically charges. When any one of the first electrical module 4 and the third electrical module 6 works, the main control module 12 controls the energy storage module 3 to disconnect the charging. When the first electrical module 4 and the third electrical module 6 do not work, the energy storage module 3 resumes charging.

Since both the microwave oven and the induction cooker are instantaneous high-energy-consuming components, and the overall structure of the microwave oven is generally much larger than that of the induction cooker, by cleverly arranging the energy storage module 3 in the space where the induction cooker is located, the power transmission between the energy storage module 3, the induction cooker and the microwave oven is more direct and efficient, reducing power loss and improving energy utilization efficiency. Thus, stable power support is provided for high-power electrical appliances such as the induction cooker and the microwave oven, avoiding problems such as the decline or damage of the electrical appliance performance caused by power fluctuations. At the same time, the internal space of the housing assembly is fully utilized, realizing the compact integration of kitchen appliances and improving the utilization rate and aesthetics of the kitchen space.
