[0022] Reference Figures 1 to 4This invention provides a solar-powered electric griddle with integrated energy storage, comprising a chassis 1, an inverter 2, an energy storage unit 3, an electric griddle cooking unit 4, and a solar power generation unit. The inverter 2 and the energy storage unit 3 are both installed inside the chassis 1, and the electric griddle cooking unit 4 is installed on the top of the chassis 1. The energy storage unit 3 and the electric griddle cooking unit 4 are both electrically connected to the inverter 2 via wires. The solar power generation unit is located outside the chassis 1. The chassis 1 is provided with a solar interface 9, and the solar power generation unit is connected to the solar interface 9 via wires. The solar interface 9 is electrically connected to the inverter 2.

[0023] The solar-powered electric griddle with integrated energy storage has three working stages: energy storage, cooking, and emergency power supply.

[0024] Energy storage stage: The solar power generation unit converts solar energy into direct current, and after the current is stabilized and current limited, it is sent to the energy storage unit 3 for energy storage. Cooking stage: Activate the electric griddle function. At this time, direct solar heating can be used. The solar power generation unit converts solar energy into DC power, which is then converted into AC power by inverter 2 to power the griddle. If the light is insufficient or the power generation is insufficient, the system switches to energy storage unit 3 for power supply. The DC power output from energy storage unit 3 is converted into AC power of the same standard as the mains power by inverter 2, and then used to power external devices through the output interface. The thermostat adjusts the heating plate temperature in real time to ensure the cooking effect.

[0025] Emergency power supply phase: When a power outage occurs, the equipment's emergency power supply mode is activated, and the energy storage unit 3 supplies power to small household appliances, making it convenient for users to plan their electricity usage reasonably.

[0026] The solar-powered electric griddle energy storage unit adopts an integrated design that combines solar power generation, energy storage, electric griddle cooking, and emergency power supply functions into one device, eliminating the need for additional wiring adapters and greatly improving ease of use.

[0027] Meanwhile, apart from the solar power generation unit, all units can be connected as a whole through the wiring built into the chassis 1, which further optimizes the overall structure, makes the size more compact, and has better portability.

[0028] The solar-powered electric griddle with integrated energy storage can achieve a closed-loop process of autonomous power generation, energy storage, cooking, and emergency power supply, solving the limitation of existing ordinary electric griddles that rely on grid power.

[0029] In addition, users do not need to purchase energy storage equipment and electric griddles separately, which reduces the user's purchase cost and subsequent maintenance cost, making it both economical and practical. It is worth noting that the solar-powered electric griddle energy storage unit is also preferably equipped with a built-in BMS energy management system. This system can monitor the power generation, remaining battery power, and working status of the griddle in real time, automatically schedule the energy flow, and prioritize the use of solar energy for cooking. Excess energy is stored in the battery, and the system automatically switches to battery power when there is insufficient sunlight, thus possessing intelligent control and output capabilities.

[0030] As an optional implementation, the solar power generation unit includes a photovoltaic panel, which is electrically connected to the inverter 2 via wires. The photovoltaic panel can receive sunlight, charge the battery, and provide power for daily household use.

[0031] The photovoltaic panel can use a high-efficiency photovoltaic cell panel with a photoelectric conversion efficiency of up to 22% to improve power generation efficiency. In addition, the photovoltaic panel can also be equipped with a built-in MPPT maximum power point tracking controller to track the peak solar power generation in real time and dynamically optimize the current and voltage output.

[0032] As an optional implementation, the electric griddle cooking unit 4 includes a base 41, a heating plate 42, a top cover 43, and an electric griddle switch 44.

The top cover 43 and the base 41 are rotatably connected by a connecting hinge 45. A handle 46 is provided at the front end of the top cover 43.

[0033] During use, the top cover 43 can be pulled by the handle 46. With the help of the connecting hinge, the top cover 43 rotates relative to the base 41, thereby exposing the heating plate 42 for cooking.

[0034] In this embodiment, the heating plate 42 is preferably made of clay material, and preferably has an anti-stick coating on its upper surface. The heating plate 42 has a built-in high-density resistance wire, and the heating power is set to 800W-1500W, which is precisely matched with the output power of the energy storage unit 3 to avoid overload shutdown.

[0035] The electric griddle cooking unit 4 can also be equipped with a thermostat and set to automatically cut off the power when the temperature reaches 230 degrees to reduce energy waste.

[0036] As an optional implementation, the energy storage unit 3 includes a battery, which is electrically connected to the inverter 2 via wires. The battery is preferably a lithium iron phosphate battery pack with a capacity of 2kWh-16kWh. After a single full charge, it can power the electric griddle for extended periods and also meet the emergency power needs of small household appliances. The battery preferably supports bidirectional charging and discharging, allowing it to power the electric griddle for cooking and store surplus energy for later emergency use. The battery can also integrate a charge / discharge protection circuit, providing quadruple protection against overvoltage, overcurrent, short circuit, and overtemperature, avoiding safety risks under battery overload or abnormal operating conditions. In addition to the battery, the energy storage unit 3 can also include a battery control board to optimize battery charging and discharging.

[0037] As an optional implementation, it also includes several power supply interfaces 5, which are disposed on the chassis 1 and are electrically connected to the circuit of the all-in-one machine. Different power supply interfaces 5 may be of the same specification or different specifications.

[0038] In this embodiment, the power supply interface 5 includes, but is not limited to, specific interface forms such as USB DC output interface and 220V AC power output interface. In terms of layout, different power supply interfaces 5 are distributed in an orderly and spaced manner. The specific number and arrangement of power supply interfaces 5 can be flexibly selected and used according to actual usage needs, without specific restrictions.

[0039] Equipped with multiple power supply interfaces, it can simultaneously meet the emergency power needs of electric griddle cooking and small household appliances, making it a multi-functional device and improving the utilization rate of equipment resources.

[0040] The power supply interface 5 can also form a linkage protection mechanism with the overall circuit to protect against overcurrent and overvoltage.

[0041] As an optional implementation, an overload protection structure 6 is also included, which is disposed on the chassis 1 and is electrically connected to the circuit of the all-in-one machine.

[0042] The overload protection structure 6 can assist the equipment in forming a protection mechanism. When an abnormal situation such as overload, short circuit, or over-temperature is detected, the equipment can automatically cut off the power supply through the overload protection structure 6. After the fault is cleared, the equipment can be manually restored to work to ensure safe use. As an optional implementation, a control panel 7 is also included. The control panel 7 is located at the front end of the chassis 1. The control panel 7 is equipped with a display screen and a power switch.

[0044] As an optional implementation, a power input interface 8 is also included, which is disposed on the chassis 1 and is electrically connected to the circuitry of the all-in-one machine.

[0045] When needed, the solar-powered electric griddle energy storage unit can also be directly connected to an external power source via the power input interface 8 to charge the battery.

[0046] As an optional implementation, the chassis 1 is provided with an air inlet 11, and a fan 12 is provided inside the chassis 1.

[0047] When the temperature inside the chassis 1 is high, the fan 12 can be turned on to introduce outside air into the chassis 1 through the air intake 11 to ventilate and dissipate heat, which helps to reduce the temperature inside the chassis 1.

[0048] As an optional implementation, the bottom of the chassis 1 is provided with rollers 13. Preferably, there are four rollers 13, which are located at the four corners. The rollers 13 enable the chassis 1 to move flexibly and with less effort.
