When the power is turned on, the wiring is connected, the heating work starts, and the power is automatically cut off after the water is boiled and the heating is completed. The electric kettle is placed on the body, the coupler is turned on, and the center of the kettle lid and the water outlet of the water valve are at the same center point. The kettle lid is made of high-temperature resistant material, with a water inlet port in the middle. The water inlet port is made of two uniform high-temperature resistant sealing materials to seal the steam from leaking, and the steam effect is better.

[0053] The machine body is provided with a control panel, which is used to detect the high and low water level signals, transmit them to the water valve, and provide the water valve with the switch and close signals; for setting the steaming time; for the buzzer prompt of steaming completion; for selecting the steaming mode, select heating, only heat the electric kettle; select hot buns for steam heating; select steaming, and you can select and press the button on the page (8 minutes for steamed buns, 15 minutes for steamed corn, 15 minutes for steamed rice rolls, 8 minutes for steamed eggs, 15 minutes for steamed egg custard, 15 minutes for steamed shrimp, and 20 minutes for steamed dumplings). Select the steamed ingredients and press the water outlet button on the control panel to output the corresponding amount of water according to the steaming time. At this time, the water valve is opened, and the water inlet port of the kettle lid is opened at the same time, and purified water begins to fill the electric kettle. After it is filled, the water valve stops discharging water, and the water outlet port of the kettle lid is closed and sealed.

[0054] The steam box is located on the top of the water filter. It is a rectangular sealed body with an open top cover for placing and taking out ingredients. Open the top cover of the steam box, place the ingredients on the steaming plate, and put down the top cover of the steam box. The top cover has air holes for exhaust. Select the steaming mode to start steaming. When the time is up, there will be a buzzer or voice prompt.
