After the drainage is finished, the power component 1101 is closed, the output shaft of the power component 1101 is reset, the push rod 140 is automatically reset under the action of the elastic component 150, and the sealing gasket 170 reseals the drainage hole 1303. The process is performed circularly, and the rice cooker 100 can achieve better blood sugar reducing effect through repeated water drainage and desugaring in the cooking process.

In some embodiments of the present application, the power unit 1101 may be a solenoid valve, or may be a micro motor and a lifting mechanism. In this embodiment, the power unit 1101 is preferably an electromagnetic valve, and a sealing ring is disposed between an output shaft of the electromagnetic valve and the cooker cover 110 for preventing air leakage during cooking of the rice cooker 100. When the electromagnetic valve is powered on, the output shaft of the electromagnetic valve passes through the pot cover 110 and contacts with the upper end of the push rod 140, so that the push rod 140 is driven to move downwards to drive the sealing gasket 170 to be far away from the water discharge hole 1303.

In this embodiment, the mounting portion 1301 is provided with an arc-shaped structure, so that a gap is formed between the outer side of the side wall of the food steamer 130 and the inner side of the side wall of the inner pot 1201, so that water in the inner pot 1201 can enter the food steamer 130 from the water inlet 1302 through the gap during cooking.

A plurality of water inlet holes 1302 are uniformly distributed in the circumferential direction on the upper portion of the side wall of the food steamer 130, and the purpose of the plurality of water inlet holes 1302 is to enable enough water to enter the food steamer 130 from the inner pot 1201 in multiple directions in preset time so as to soak rice grains in the food steamer 130. The purpose of the water inlet 1302 at the upper portion of the side wall of the basket 130 is to prevent water in the inner pot 1201 from entering the basket 130 due to boiling of the water when no more water is needed to fill the rice grains in the basket 130.

The bottom end of the food steamer 130 is provided with a plurality of drain holes 1303, when the electric cooker 100 is not draining water and desugaring, the plurality of drain holes 1303 are shielded and sealed by the sealing gasket 170, so that the water in the inner pot 1201 is prevented from entering the food steamer 130 through the drain holes 1303 or the water in the food steamer 130 flows into the inner pot 1201 through the drain holes 1303. When the electric cooker 100 drains water and removes sugar, the sealing pad 170 is separated from the drain hole 1303, and water in the food steamer 130 enters the inner pot 1201 through the drain hole 1303, so that the hidden danger of power utilization caused by contact of the water with other electrified parts is avoided. In this embodiment, the bottom end of the food steamer 130 is provided with a through hole for the push rod 140 to pass through, and the plurality of drain holes 1303 are uniformly distributed around the circumference of the through hole, that is, the plurality of drain holes 1303 are uniformly distributed around the circumference of the push rod 140, so that the purpose of such arrangement is that on one hand, the water in the food steamer 130 is fully drained, and on the other hand, the sealing gasket 170 is favorable for more conveniently sealing the drain holes 1303.

The bottom end of the guide sleeve 160 is fixedly connected with the top end of the convex hull.

In this embodiment, a convex hull is disposed at the bottom end of the steamer 130, and the drain holes 1303 are uniformly distributed on the sidewall of the convex hull in the circumferential direction, which is beneficial to further improving the drainage effect. The fact that the upper portion of the sealing gasket 170 is sunk inside the convex hull is advantageous to further improve the effect of the sealing gasket 170 closing the water discharge hole 1303.

Referring to fig. 4 to 6, in some embodiments of the present application, the upper end of the push rod 140 extends radially outward to form a first annular boss 1402, the outer diameter of the first annular boss 1402 matches the inner diameter of the guide sleeve 160, the lower portion of the guide sleeve 160 extends radially inward to form a third annular boss 1602, and one end of the elastic member 150 abuts against the bottom end of the first annular boss 1402, and the other end abuts against the top end of the third annular boss 1602. The tip of the first annular boss 1402 extends radially outwardly therealong to form a second annular boss 1403, the second annular boss 1403 cooperating with the tip of the guide sleeve 160 to limit the downward displacement of the pushrod 140. In this embodiment, the outer side of the push rod 140 is sleeved with the guide sleeve 160, so as to facilitate installation of the elastic component 150, ensure that the push rod 140 is always in a vertical state, and limit downward displacement of the push rod 140.

In some embodiments of the present application, the outer side wall of the lower end of the guide sleeve 160 is provided with a second annular groove 1601, and the second annular groove 1601 is snapped into a surrounding portion of the hole, so that the bottom end of the guide sleeve 160 is fixedly connected to the bottom end of the food steamer 130 or the top end of the convex hull. In other embodiments, the lower end of the guiding sleeve 160 may be directly fixedly connected to the bottom end of the basket 130 or the top end of the convex hull by welding, or the guiding sleeve 160 may be integrally formed with the basket 130.

In some embodiments of the present application, the elastic member 150 may be a coil spring, or may be a plurality of disc springs. In this embodiment, the elastic member 150 is preferably a coil spring, the coil spring is sleeved outside the push rod 140, one end of the coil spring abuts against the bottom end of the first annular boss 1402, the other end abuts against the top end of the third annular boss 1602, and the coil spring drives the push rod 140 to reset.

In this embodiment, the gasket 170 is selected according to the shape of the portion of the basket 130 where the drain hole 1303 is located. For example, when the bottom end of the food steamer 130 is not provided with the convex hull, the drain holes 1303 are uniformly distributed at the bottom end of the food steamer 130 around the circumference of the push rod 140, and the sealing pad 170 can be in the form of a flat pad; when the bottom end of the steamer 130 is provided with the convex hulls, the drain holes 1303 are uniformly distributed on the side walls of the convex hulls in the circumferential direction, the shape of the upper parts of the sealing gaskets 170 is matched with the shape of the convex hulls, the upper parts of the sealing gaskets 170 are immersed into the convex hulls to seal the drain holes 1303, and the shapes of the sealing gaskets 170 can be adjusted according to the shapes of the convex hulls.

The working process is as follows:

A proper amount of water is added into the inner pot 1201, rice is put into the food steamer 130, a rice cooking mode is started, and after the water in the inner pot 1201 is heated and boiled, the water enters the food steamer 130 through the water inlet 1302 to soak the rice grains. After the rice grains are soaked for a predetermined time, the electromagnetic valve is powered on, the output shaft of the electromagnetic valve penetrates through the cooker cover 110 to be in contact with the upper end of the push rod 140 so as to drive the push rod 140 to move downwards, the push rod 140 moves downwards so as to drive the sealing gasket 170 to be away from the water discharge hole 1303, and the electric cooker 100 discharges water and removes sugar. After the drainage is finished, the electromagnetic valve is powered off, the output shaft of the electromagnetic valve is reset, the push rod 140 is automatically reset under the action of the elastic component 150, and the sealing gasket 170 seals the drainage hole 1303 again. The second round cooking mode is started, the process is executed circularly, and the electric cooker 100 can achieve a better blood sugar reducing effect through multiple times of water drainage and desugaring in the cooking process.
