Pad 54, the end face of the gasket 54 closes the pressure relief port 70, and the gasket 54 has a sealing plug 56 that extends into the valve port 50. Since the sealing plug 56 extends into the valve port 50, the end surface of the gasket 54 closes the pressure relief port 70. Therefore, when the push rod 52 moves downward, the gasket 54 first leaves the pressure relief port 70, and the pressure relief port 70 is opened. The pusher 52 continues to move downward until the sealing plug 56 is completely disengaged from the valve port 50 and the valve port 50 is in the open state. Similarly, when it is necessary to close the valve port 50 and the pressure relief port 70, the valve port 50 is first closed, and then the pressure relief port 70 is closed. When it is necessary to open the pressure relief port and close the valve port 50, it is only necessary to place the push rod 52 between the above two state positions.

In the embodiment of the present invention, the safety hole 95 is a tapered hole, and the valve post 94 has a spherical structure and is closely matched with the safety hole 95. When the internal pressure of the inner tank 4 is greater than the pressure of the spool 94, the atmosphere in the inner tank 4 pushes up the spool 94 to relieve the pressure, thereby preventing the internal pressure of the inner tank 4 from being excessively large and causing a hazard.

Used by the device. When used as a water storage tank, the above-mentioned opening and closing valve 5 is an automatic water discharge mechanism, and the valve port 50 is a water leakage port.

Referring to FIG. 8 and in conjunction with FIG. 13, the motor 61 is controlled by a microcomputer on the multi-function rice cooker. 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, and The peripheral surface of the first cam 62 having a larger 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, and pushing the up-and-down stroke slider 63 vertically downward. And transmitting 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 When the downward movement distance is greater than 0, the water leakage port is opened, and the water flows into the inner tank 4 through the water leakage port. 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 peripheral surface of the first cam 62 with a small eccentricity to the upper and lower sides. When the stroke slider 63 comes into contact, at this time, the urging 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 first cam 62. The contact of the end faces, at the same time, the gasket 54 is also moved upwards, and the water leakage port is blocked again, and the water discharge stops. 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 rice cooker is used as a pressure cooker, it can effectively prevent the occurrence of the steam burn story by controlling the release 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 excessive soaking of the rice grains, especially suitable for busy office workers. When the inner casing 3 is used as a rice soup collecting container, the valve port 50 is a rice soup outlet.
