When the predetermined water discharge time is reached, the microcomputer sends a signal, the motor 61 is powered on, and the motor 61 drives the first cam 62 to rotate. The circumferential surface of the first cam 62 having a large eccentricity is rotated to contact with the up-and-down stroke slider 63 and stopped, thereby converting the rotational force of the motor 61 into a vertical downward force, pushing the upper and lower stroke sliders 63 vertically downward. Move and transfer the force to the push rod 52 while compressing the first return spring 53 to move the seal 54 at the lower end of the stroke push rod 52 downward. When the vertical displacement downward distance is greater than 0, the water leakage opening is opened and the water is leaked. The mouth flows into the bladder 4. When the water discharge amount reaches the set value or the water discharge time reaches the set time, the microcomputer again sends a signal to drive the motor 61 to rotate, and the first cam 62 is rotated to rotate the first cam 62 with a smaller eccentricity to the upper and lower strokes. When the block 63 is in contact, at this time, the acting force acting on the up-and-down stroke slider 63 disappears, and due to the reaction force of the first return spring 53, the push rod 52 moves the up-and-down stroke slider 63 up and continues to hold the end face of the first cam 62. When the contact is made, the gasket 54 is also moved up correspondingly, and the water leakage port is blocked again, and the water is stopped. When it is necessary to add water to the water storage box, first open the cover 22 and directly add water.

When the multi-function electric cooker is used as a pressure cooker, it can effectively prevent the occurrence of steam burn stories by controlling the discharge of water into the inner tank 4, and has high safety and reliability.

The microcomputer is used to control the driving device to convert the force into a vertically downward force through the transmission mechanism to achieve the purpose of pressing or loosening the up and down stroke slider 63, so that the time of discharging water and the amount of water discharge can be artificially set, for example, one hour before cooking, This will not affect the taste of the rice because the rice is soaked for too long, and at the same time ensure that the nutrition will not be lost due to the excessive soaking of the rice grains, especially suitable for busy office workers.
