The output port of the micro blower 10 is square. The output ports of the adapter 11 and the first hose 12 are both circular interfaces with an inner diameter of 10 mm and an outer diameter of 12 mm.
[0029] Adopting the above scheme: The micro blower 10 is started by judging whether the rice is in a boiling state through the temperature of the steam emerging from the inside of the steam hole 7, so that the micro blower 10 blows air inside the device to play the function of preventing the pot from overflowing. When there is no overflow, the temperature can be controlled by detecting the bottom temperature sensor 4 according to the set taste, and the high and low fire can be controlled to adjust the hardness and softness of the rice, thereby shortening the cooking time.
[0030] As Figures 1 to 6 shown, a check valve 13 is installed at one end of the first hose 12. A second hose 14 is provided at one end of the check valve 13. The output end of the check valve 13 communicates with the second hose 14. The second hose 14 extends 3 mm into the rice cooker lid 6 through the opening at the top end of the rice cooker lid 6.
[0031] As Figures 1 to 6 shown, several groups of air inlet holes 9 are arranged at equal intervals on the outer wall of the rice cooker lid 6. The output end of the micro blower 10 communicates with an adapter 11. The output end of the adapter 11 communicates with a first hose 12. The output end of the first hose 12 communicates with a check valve 13.
[0032] Adopting the above solution: By starting the micro blower 10, the micro blower 10 can blow air into the pot through the air inlet hole 9, the first hose 12 and the second hose 14, so as to reduce the temperature on the surface of the boiling water during rice cooking, and at the same time break the bubbles generated by the boiling of the rice soup, thereby achieving the function of preventing the pot from overflowing. And by setting the check valve 13, it can prevent the steam in the pot from flowing back into the interior of the micro blower 10 when the micro blower 10 is not in operation.
[0033] As Figures 1 to 6 shown, a rice cooker heater 2 is fixed to the bottom end of the rice cooker main body 1, and a support leg 3 is fixed to the bottom end of the rice cooker heater 2. There are four groups of support legs 3 fixed to the bottom end of the rice cooker heater 2, and the support legs 3 are arranged at equal intervals about the central axis of the rice cooker heater 2.
[0034] As Figures 1 to 6 shown, a bottom temperature sensor 4 is fixedly installed in the middle of the inner wall of the rice cooker heater 2. The top end of the bottom temperature sensor 4 is movably connected to the inner pot 18. The inner pot 18 is movably connected inside the rice cooker heater 2. The inner wall of the rice cooker main body 1 is close to the outer wall of the inner pot 18, and the rice cooker main body 1 and the inner pot 18 are movably connected.
[0035] As Figures 1 to 6 shown, a handle 15 is fixed to the top end of the rice cooker lid 6. A control knob 16 is installed on the outer wall of the rice cooker main body 1. A signal indicator light 17 is fixed to the outer wall of the rice cooker main body 1. There are two groups of signal indicator lights 17, and the signal indicator lights 17 are symmetrically distributed about the central axis of the control knob 16.
[0036] Adopting the above solution: Open the rice cooker lid 6 through the handle 15. After taking out the inner pot 18, put the washed rice into the inner pot 18. Then put the inner pot 18 back into the rice cooker main body 1 and make the bottom end of the inner pot 18 contact the rice cooker heater 2. Start the rice cooker heater 2 through the control knob 16. The electromagnetic heating coil 5 inside the rice cooker heater 2 will heat the inner pot 18, and then steam the rice placed inside the inner pot 18. And the colors of the two groups of signal indicator lights 17 are red and green. During the steaming process, the red light will turn on to prompt the user that the device is in a high-temperature state and in a dangerous state. After the rice inside is steamed, the green light will turn on to prompt the user that the rice has been steamed.
[0037] Working principle and usage process of the utility model: Open the rice cooker lid 6 through the handle 15. After taking out the inner pot 18, put the washed rice into the inner pot 18. Then put the inner pot 18 back into the rice cooker main body 1 and make the bottom end of the inner pot 18 contact the rice cooker heater 2. Start the rice cooker heater 2 through the control knob 16. The electromagnetic heating coil 5 inside the rice cooker heater 2 will heat the inner pot 18, and then cook the rice placed inside the inner pot 18. And the colors of the two signal indicators 17 are red and green. During the cooking process, the red light will be on to prompt the user that the device is in a high-temperature and dangerous state. After the rice inside is cooked, the green light will be on to prompt the user that the rice has been cooked. Judge whether the rice is in a boiling state by the temperature of the steam coming out of the steam hole 7 to start the micro blower 10, so that the micro blower 10 blows air inside the device to play the function of preventing overflow. When there is no overflow, the temperature can be controlled according to the set taste by detecting the bottom temperature sensor 4, and the size of the fire can be controlled to adjust the hardness and softness of the rice, thereby shortening the cooking time. By starting the micro blower 10, the micro blower 10 can blow air into the pot through the air inlet hole 9, the first hose 12 and the second hose 14 to reduce the temperature of the boiling water surface during cooking, and at the same time break the bubbles generated by the boiling of the rice soup, so as to achieve the function of preventing overflow. And by setting the check valve 13, it can prevent the steam in the pot from flowing back into the micro blower 10 when the micro blower 10 is not working.
[0038] The device can cook rice with high heat while preventing overflow during cooking, ensuring the aroma and taste of the rice, eliminating the safety hazards brought by overflow, such as significantly reducing the risks of electric shock, short circuit and scalding, making the kitchen environment safer, and avoiding the soup and rice grains from soiling the kitchen countertop, floor and cooking utensils, reducing the burden of cleaning work, keeping the kitchen clean and hygienic. After solving the overflow problem, the cooking process is more smooth and controllable, reducing the occurrence of accidents and enhancing the pleasure and sense of achievement of cooking.
