[0041] This application takes the example that the power component 1101 is connected to the rice cooker cover 110 to describe the specific structure of the rice cooker 100 in detail. The specific structure is as follows:

[0042] The sealing gasket 170 is arranged outside the bottom end of the steamer 130 to close the drain hole 1303. The push rod 140 is arranged vertically on the steamer 130 and staggered with the drain hole 1303. The lower end of the push rod 140 passes through the bottom end of the steamer 130 and is fixedly connected to the sealing gasket 170. The outer side of the push rod 140 is sleeved with a guide sleeve 160 for guiding. The guide sleeve 160 is staggered with the drain hole 1303, and its bottom end is fixedly connected to the bottom end of the steamer 130. An elastic component 150 for resetting the push rod 140 is arranged between the push rod 140 and the guide sleeve 160. The elastic component 150 is sleeved on the outer side of the push rod 140. The power component 1101 is connected in the pot cover 110. The output shaft of the power component 1101 passes through the pot cover 110 and contacts the upper end of the push rod 140.

After the rice grains are soaked for a predetermined time, the power component 1101 is started, and the power component 1101 drives the push rod 140 to move downward to drive the sealing pad 170 away from the steamer 130, and the sealing pad 170 is separated from the drainage hole 1303, and the water in the steamer 130 is discharged through the drainage hole 1303, and the electric rice cooker 100 is drained and desugared. After the drainage is completed, the power component 1101 is turned off, 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 pad 170 reseals the drainage hole 1303. This process is executed cyclically, and the electric rice cooker 100 can achieve a better blood sugar reduction effect by draining and desugaring multiple times during the cooking process.

[0043] In some embodiments of the present application, the power component 1101 can be a solenoid valve, or a micro motor plus a lifting mechanism. In this embodiment, the power component 1101 is preferably a solenoid valve, and a sealing ring is provided between the output shaft of the solenoid valve and the pot cover 110 to prevent the electric rice cooker 100 from leaking during the cooking process. When the solenoid valve is powered on, its output shaft passes through the pot cover 110 and contacts the upper end of the push rod 140, thereby driving the push rod 140 to move downward to drive the sealing pad 170 away from the drain hole 1303. The solenoid valve is powered off and reset, and the push rod 140 automatically resets under the action of the elastic component 150, and the sealing pad 170 reseals the drain hole 1303.

[0044] Reference Figure 3In some embodiments of the present application, the shape of the steamer 130 matches the shape of the inner pot 1201, and a mounting portion 1301 is provided at the top of the steamer 130. The top of the inner pot 1201 contacts the mounting portion 1301 to support the steamer 130, and the steamer 130 is disposed as a whole at the upper part of the inner side of the inner pot 1201, so that there is a certain distance between the bottom end of the steamer 130 and the bottom end of the inner pot 1201, so as to prevent water from entering the steamer 130 from the drainage hole 1303 when the steamer 130 is draining water. In this embodiment, the mounting portion 1301 is configured as an arc structure, so that there is a certain gap between the outer side of the side wall of the steamer 130 and the inner side of the side wall of the inner pot 1201, so that the water in the inner pot 1201 can enter the steamer 130 from the water inlet hole 1302 through the gap when cooking.

[0045] A plurality of water inlet holes 1302 are evenly distributed in the circumferential direction on the upper side wall of the steamer 130. The purpose of providing the plurality of water inlet holes 1302 is to allow a sufficient amount of water to enter the steamer 130 from the inner pot 1201 in multiple directions within a predetermined time to soak the rice grains in the steamer 130. The purpose of providing the water inlet holes 1302 on the upper side wall of the steamer 130 is to prevent the water in the inner pot 1201 from boiling and entering the steamer 130 when the rice grains in the steamer 130 do not need to be refilled with water.

[0046] A plurality of drainage holes 1303 are provided at the bottom of the steamer 130. When the electric rice cooker 100 is not draining and desugaring, the plurality of drainage holes 1303 are blocked and sealed by the sealing gasket 170 to prevent the water in the inner pot 1201 from entering the steamer 130 through the drainage holes 1303 or the water in the steamer 130 from flowing into the inner pot 1201 through the drainage holes 1303. When the electric rice cooker 100 is draining and desugaring, the sealing gasket 170 is separated from the drainage holes 1303, and the water in the steamer 130 enters the inner pot 1201 through the drainage holes 1303, to prevent the water from contacting other live parts and causing electrical hazards. In this embodiment, a through hole is opened at the bottom end of the steamer 130 for the push rod 140 to pass through, and multiple drainage holes 1303 are evenly distributed around the through hole, that is, multiple drainage holes 1303 are evenly distributed around the push rod 140. The purpose of such arrangement is, on the one hand, to facilitate the full discharge of water in the steamer 130, and on the other hand, to facilitate the sealing gasket 170 to close the drainage holes 1303 more conveniently.

[0047] In some embodiments of the present application, the middle of the bottom end of the steamer 130 bulges upward to form a convex bulge, a through hole for the push rod 140 to pass through is provided at the top of the convex bulge, a plurality of drainage holes 1303 are evenly distributed on the side wall of the convex bulge, the upper part of the sealing gasket 170 is immersed in the inner side of the convex bulge to close the plurality of drainage holes 1303, and the lower end of the push rod 140 passes through the top of the convex bulge and is fixedly connected to the sealing gasket 170. The bottom end of the guide sleeve 160 is fixedly connected to the top of the convex bulge.

[0048] In this embodiment, a convex bulge is provided at the bottom end of the steamer 130, and the drainage holes 1303 are evenly distributed on the side wall of the convex bulge to further improve the drainage effect. The upper part of the sealing gasket 170 is immersed in the inner side of the convex bulge to further improve the effect of the sealing gasket 170 in closing the drainage holes 1303.

[0049] refer to Figures 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, and the lower part of the guide sleeve 160 extends radially inward to form a third annular boss 1602. One end of the elastic component 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 top end of the first annular boss 1402 extends radially outward to form a second annular boss 1403, and the second annular boss 1403 cooperates with the top end of the guide sleeve 160 to limit the downward displacement of the push rod 140. In this embodiment, the outer side of the push rod 140 is fitted with the guide sleeve 160 to facilitate the installation of the elastic component 150, to ensure that the push rod 140 is always in a vertical state, and to limit the downward displacement of the push rod 140.

[0050] In some embodiments of the present application, a second annular groove 1601 is formed on the outer side wall of the lower end of the guide sleeve 160, and the portion around the through hole is inserted into the second annular groove 1601, so that the bottom end of the guide sleeve 160 is fixedly connected to the bottom end of the steamer 130 or the top end of the convex bulge. In other embodiments, the lower end of the guide sleeve 160 can be directly fixedly connected to the bottom end of the steamer 130 or the top end of the convex bulge by welding, or the guide sleeve 160 and the steamer 130 are integrally formed.

[0051] In some embodiments of the present application, the elastic component 150 may be a coil spring or a plurality of disc springs. In this embodiment, the elastic component 150 is preferably a coil spring, which is sleeved on the outside of the push rod 140, one end of the coil spring 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, and the coil spring drives the push rod 140 to reset.

[0052] In some embodiments of the present application, a first annular groove 1401 is formed on the side wall of the lower end of the push rod 140, and an annular clamping block 1701 is provided on the inner wall of the sealing gasket 170 to be clamped with the first annular groove 1401. The annular clamping block 1701 is clamped into the first annular groove 1401 to fix the lower end of the push rod 140 with the sealing gasket 170. In this embodiment, the sealing gasket 170 can be selected according to the shape of the part of the steamer 130 where the drainage hole 1303 is located. For example, when there is no bulge at the bottom end of the steamer 130, the drainage holes 1303 are evenly distributed around the push rod 140 at the bottom end of the steamer 130. At this time, the sealing gasket 170 can be in the form of a flat pad; when a bulge is set at the bottom end of the steamer 130, the drainage holes 1303 are evenly distributed on the side wall of the bulge. At this time, the upper shape of the sealing gasket 170 matches the shape of the bulge, and the upper part of the sealing gasket 170 is immersed in the bulge to close the drainage holes 1303. The shape of the sealing gasket 170 can be adjusted according to the shape of the bulge.

[0053] The working process is as follows:

[0054] Before the electric rice cooker 100 is put into operation, the sealing gasket 170 closes the drainage hole 1303. An appropriate amount of water is added to the inner pot 1201, and the rice is placed in the steamer 130, and the cooking mode is turned on. When the water in the inner pot 1201 is heated and boiled, the water enters the steamer 130 through the water inlet 1302 to soak the rice grains. After the rice grains are soaked for a predetermined time, the solenoid valve is energized, and its output shaft passes through the pot cover 110 and contacts the upper end of the push rod 140 to drive the push rod 140 to move downward, and the push rod 140 moves downward to drive the sealing gasket 170 away from the drainage hole 1303, and the electric rice cooker 100 drains and removes sugar. After the drainage is completed, the solenoid valve is de-energized, and its output shaft is reset. The push rod 140 automatically resets under the action of the elastic component 150, and the sealing gasket 170 re-seals the drainage hole 1303. The second round of cooking mode is turned on, and the process is executed cyclically. The electric rice cooker 100 can achieve a better blood sugar reduction effect by draining and removing sugar multiple times during the cooking process.

[0055] The electric rice cooker using the technical solution can drain and remove sugar for multiple times during the cooking process, and has a simple structure, convenient assembly and disassembly, and good user experience.

[0056] In another embodiment of the present application, when the output shaft of the power component 1101 passes through the pot cover 110 and is fixedly connected to the upper end of the push rod 140 by a coupling or other means (such as welding, etc.), it is not necessary to set the elastic component 150 and the guide sleeve 160. The power component 1101 can directly drive the push rod 140 to move up and down to drive the sealing gasket 170 to move close to or away from the drainage hole 1303.

[0057] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
