[0049] like Figure 6 The heating tank 223 is divided into a first chamber 2233 and a second chamber 2234 by a partition device. The first chamber 2233 is connected to the first opening 2231, and the second chamber 2234 is connected to the second opening 2232. The electric heating tubes 221 are evenly distributed in the first chamber 2233 to ensure that the water is heated evenly during the heating process and to improve the quality of steam. The first chamber 2233 is provided with a water inlet hole 2235, which is connected to the second chamber 2234. The second chamber 2234 is used to hold water and continuously replenishes water to the first chamber 2233 through the water inlet hole 2235 to ensure that the water level in the first chamber 2233 is stable and to avoid dry burning.

[0050] The heating tank 223 is divided into a first chamber 2233 and a second chamber 2234 by a partition device. The first chamber 2233 is used for heating and generating steam, while the second chamber 2234 is used to hold replenished water. The partition device separates the heating area and the water replenishment area, allowing the electric heating tube 221 to concentrate on heating the water in the first chamber 2233, reducing heat loss, thereby improving heating efficiency and accelerating steam generation. A drain port 2236 can be provided at the bottom of the second chamber 2234 for easy periodic cleaning of scale and impurities.

[0051] The water replenishment device 23 includes a water replenishment tank 231, a water inlet pipe 232, and a water pump 233. The two ends of the water inlet pipe 232 are respectively connected to the water replenishment tank 231 and the water pump 233. The water replenishment tank 231 is connected to the second chamber 2234 through the second opening 2232. The water replenishment tank 231 includes a water inlet 2311 for connecting to the water inlet pipe 232. A one-way valve 2312 is installed at the water inlet 2311. A water filling conduit 234 is provided inside the water replenishment tank 231, which is connected to the water inlet 2311. The water filling conduit 234 extends into the heating tank 223 through the second opening 2232.

[0052] The water replenishment device 23 can automatically replenish water to the heating tank 223, ensuring the normal operation of the heating device 22. The one-way valve 2312 prevents water backflow, ensuring the stability and safety of the water replenishment process. By setting the water supply pipe 234, the water flow direction can be optimized, allowing the water to enter the first chamber 2233 more smoothly, reducing water flow resistance and improving water replenishment efficiency.

[0053] like Figure 6 The water supply tank 231 is equipped with a float switch 235, which is electrically connected to the water pump 233. The water level is detected by the up-and-down movement of the float. When the water level drops to the set minimum level, the float switch 235 triggers a signal, controlling the water pump 233 to start and supply water to the water supply tank 231. When the water level rises to the set maximum level, the float switch 235 triggers a signal again, controlling the water pump 233 to stop working. The water supply pipe 234 is also provided to prevent the addition of water from affecting the sensing of the float switch 235.

[0054] A balancing conduit 25 is provided between the steam storage device and the water supply tank 231. The balancing conduit 25 is used to balance the pressure between the steam storage device and the water supply tank 231 to prevent system instability caused by pressure difference.

[0055] like Figure 5 , Figure 6 The steam pipeline assembly 21 components include a pressure sensor 212, a pressure relief valve 213, a temperature sensor 214, a pressure bypass valve 216, and a safety valve 215. The installation of these components ensures the safe operation of the steam pipeline system and prevents accidents caused by excessive pressure or temperature. It ensures stable pressure and temperature during steam output, effectively eliminating temperature differences through precise temperature control and steam output, ensuring even heating of food and improving cooking results. This rapid output function significantly shortens cooking time and improves cooking efficiency.

[0056] Pressure sensor 212 and temperature sensor 214 enable real-time monitoring of steam pressure and temperature for precise control. Pressure bypass valve 216, pressure relief valve 213, and safety valve 215 are electrically connected to pressure sensor 212 and automatically open when pressure or temperature exceeds set values, releasing excess pressure or steam and protecting the system from damage. Pressure sensor 212 and temperature sensor 214 are electrically connected to AC contactor 222. Based on feedback signals from temperature sensor 214 and pressure sensor 212, AC contactor 222 automatically adjusts the on / off state of electric heating element 221 to ensure that water temperature and steam pressure are always maintained within a suitable range. This precise temperature control not only improves heating efficiency but also avoids energy waste caused by overheating.
