[0033] The hardness detection assembly is arranged inside the pot cover 2, and the hardness detection assembly includes a force sensor 5, a pressure plate 6, a slide rod 13, a connecting column 14, a spring 15, a connecting plate 16, a threaded rod 17, a first gear 18, a second motor 19, a threaded sleeve 20 and a second gear 21. The second motor 19 is screwed inside the pot cover 2, and the threaded sleeve 20 rotates and penetrates the surface of the pot cover 2;
[0034] Two grooves 9 are formed on the surface of the inner container 8 .
[0035] The first rotating cover 4 is threadedly connected to the surface of the pot cover 2 , and the second rotating cover 7 is threadedly connected to the water storage barrel 11 .
[0036] The first gear 18 is mounted on the output shaft of the second motor 19 , and the second gear 21 is mounted on the threaded sleeve 20 . The surface of the second gear 21 meshes with the surface of the first gear 18 .
[0037] The surface of the threaded rod 17 is connected to the inner thread of the threaded sleeve 20 , the pressing plate 6 is welded to the threaded rod 17 , and the lower end of the connecting column 14 is rotatably connected to the upper end of the threaded rod 17 .

[0040] When it is necessary to soften the rice by adding water to the rice being cooked, first, rotate the first rotary cover 4 to remove the first rotary cover 4, then rotate the second rotary cover 7 to remove the second rotary cover 7, then inject water into the water storage barrel 11, and then close the second rotary cover 7 and the first rotary cover 4.
[0041] Secondly, start the first motor 10 to drive the sealing baffle 12 to rotate, and control the water discharge rate of the water barrel 11 by the degree to which the sealing baffle 12 no longer covers the water outlet of the water barrel 11. At the same time, the water discharge amount of the water barrel 11 is controlled by controlling the first motor 10. After adding a suitable amount of water to the rice, close the sealing baffle 12.

Because the pressure of the spring is only related to its deformation, the rate of change of the indication of the force sensor 5 is constant. When the pressing plate 6 contacts with the rice, the pressing plate 6 is subjected to the force of the rice and the force applied by the threaded rod 17, which are opposite to each other, resulting in a slowdown in the movement rate of the pressing plate 6, thereby resulting in a decrease in the rate of change of the indication of the force sensor 5. The degree of decrease in the rate of change of the indication of the force sensor 5 is used to keep the softness and hardness of the rice constant.
[0043] By setting the sealing baffle 12 in the water adding component, the sealing baffle 12 can completely cover the water outlet of the water storage barrel 11. The first motor 10 controls the opening degree of the sealing baffle 12, and then controls the water outlet rate of the water storage barrel 11, so as to avoid the water flow rate being too fast, causing the temperature of a certain part of the rice to drop too much, thereby affecting the taste of the steamed rice. By controlling the water outlet rate, it is guaranteed to add water to the maximum extent without affecting the local taste of the rice, thereby ensuring the taste of the steamed rice.
[0044] By setting the pressing plate 6 in the softness and hardness detection component, the movement rate will change after the pressing plate 6 contacts the rice, and then the softness and hardness of the rice is constant through the change degree of the force growth rate of the force sensor 5, so that the softness and hardness of the rice can be evaluated by data, so as to better judge the softness and hardness of the rice for the rice cooker, so that the user can choose whether to add water to adjust the taste according to the softness and hardness determined by the user, and whether the amount of water is sufficient according to the user's judgment on the softness and hardness of the rice, so as to choose whether to add water to change the taste.
[0045] By providing two grooves 9 , it is easier and more convenient to take out the inner liner 8 , thereby reducing the difficulty of taking out the inner liner 8 .

[0047] When it is necessary to soften the rice by adding water to the rice being cooked, first, rotate the first rotary cover 4 to remove the first rotary cover 4, then rotate the second rotary cover 7 to remove the second rotary cover 7, then inject water into the water storage barrel 11, and then close the second rotary cover 7 and the first rotary cover 4.
[0048] Secondly, start the first motor 10 to drive the sealing baffle 12 to rotate, and control the water discharge rate of the water barrel 11 by the degree to which the sealing baffle 12 no longer covers the water outlet of the water barrel 11. At the same time, the water discharge amount of the water barrel 11 is controlled by controlling the first motor 10. After adding a suitable amount of water to the rice, close the sealing baffle 12.
