Problems solved by technology

[0002] It is pointed out in the relevant technology that during the cooking process of the rice cooker, as the soaking time elapses and the water temperature rises, the surface of the rice grains begins to gelatinize and become sticky, and the rice grains will stick together to form rice balls. The thermal conductivity is far lower than that of water, so the agglomerated rice grains will hinder the uniform transfer of heat to the whole pot of rice, causing the rice grains wrapped in the middle of the rice balls to fail to fully gelatinize because they cannot absorb water.
Moreover, because the rice in the electric rice cooker is heated unevenly on the upper and lower layers, the gelatinization degree of the rice in different positions in the rice cooker is also inconsistent, so that the rice in some places has been excessively gelatinized and rotten, while the rice in some places has not been completely gelatinized. Gelatinization, resulting in a large difference in the uniformity of rice ripening in the whole pot, affecting the taste of rice

Embodiment 1

[0069] Such as figure 2 and image 3 As shown, the pressure limiting valve 11 is a sphere 111, the lid 4 has an arc-shaped slideway 421, the vent 40 runs through the bottom end of the arc-shaped slideway 421, and the sphere 111 is slidably arranged on the arc-shaped slideway 421 and often Abutting against the vent 40 to close the vent 40 , the exhaust mechanism 12 can push the ball 111 to slide upward along the arc slideway 421 to open the vent 40 . Such as figure 2 As shown, the pot cover 4 can include an outer cover and a cover plate 41, the cover plate 41 is arranged at the bottom of the outer cover, the ventilation device 1 can be arranged between the outer cover and the cover plate 41, and the center of the cover plate 41 can have a through installation hole, the mounting hole can be installed with a support block 42, the arc-shaped slideway 421 is formed by the upper surface of the support block 42 being recessed downward, and the vent 40 can pass through the support...

Embodiment 2

[0078] Such as Figure 4 and Figure 5 As shown, the structure of the present embodiment is substantially the same as that of the first embodiment, wherein the same components are designated with the same reference numerals, and the only difference is that the second embodiment uses a cam assembly instead of the electromagnet 123 in the first embodiment. Wherein, the cam component may be a motor 124 with a cam 1242 .

[0079] Specifically, refer to Figure 4 and Figure 5 , the exhaust mechanism 12 includes: a motor 124 and a cam 1242, the motor 124 has an output shaft 1241, the cam 1242 is installed on the output shaft 1241 to be driven to rotate by the motor 124, the linkage 121 is located between the cam 1242 and the sphere 111, and the motor 124 During the rotation of the driving cam 1242, the outer peripheral surface of the cam 1242 can push the right end surface of the linkage 121 to make the linkage 121 translate in the left and right direction. 121 contact (such as...

Embodiment 3

[0083] Such as Figure 6 and Figure 7 As shown, the structure of the present embodiment is substantially the same as that of the first embodiment, wherein the same components use the same reference numerals, and the differences include: the magnetic valve 125 is used in the third embodiment to replace the electromagnet 123 in the first embodiment, And the movement direction of the ball 111 is the vertical direction.

[0084] Specifically, the sphere 111 is movable up and down above the vent 40, the exhaust mechanism 12 is a magnetic valve 125, and the ventilation device 1 is configured such that when the magnetic valve 125 is energized, the magnetic valve 125 attracts the sphere 111 to move upwards to open the vent. 40. refer to Figure 6 and Figure 7 , the magnetic valve 125 can be set above the sphere 111, and the magnetic valve 125 can generate magnetic force to attract the metal material sphere 111 to move upwards, thereby opening the vent 40. When the magnetic valve...

Abstract

The invention discloses an electric rice cooker and a cooking control method thereof. The electric rice cooker comprises an air extracting device. The air extracting device is configured in a way that when the temperature of soup in a cooking cavity is increased to a sudden boiling temperature T(sudden boiling), the air extracting device extracts air in the cooking cavity to the outside, and therefore the soup in the cooking cavity suddenly boils, wherein T(sudden boiling)<T(boiling), and T(boiling) is the boiling temperature of the soup in the cooking cavity under the external air pressure of the electric rice cooker. When the air extracting device extracts air in the cooking cavity to the outside, the cooking cavity is isolated from the exterior of the electric rice cooker, and therefore the pressure in the cooking cavity is lower than the external air pressure of the electric rice cooker. With respect to the electric rice cooker, the sudden boiling process can be achieved, the caking problem of rice can be relieved, and mouthfeel and color of rice can be optimized.
