Detailed Description

In order to better understand the purpose, structure and function of the present invention, a draining mechanism and a cooking appliance of the present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, the electric cooking appliance of the present invention, taking an electric cooker as an example, includes a cooker body, an inner pot 1 and a draining mechanism, wherein the draining mechanism discharges excess rice water from a draining passage by controlling the opening and closing of a draining port 12 at the bottom of the inner pot 1, so as to make desugared rice.

In order to control the opening and closing of the draining port 12, the draining mechanism comprises a closing disc 2 and a driving mechanism. The bottom of the inner pot 1 is formed with a positioning groove 11, the aperture of the positioning groove 11 is gradually reduced from top to bottom, and the bottom of the positioning groove 11 is provided with a draining port 12. The driving mechanism controls the closing disk 2 to lift in the positioning groove 11. So that when the closing disc 2 is seated on the draining opening 12, the closing lid closes the draining opening 12; when the sealing disc 2 is separated from the draining port 12, the sealing cover opens the draining port 12 to drain water.

As shown in fig. 2, in order to ensure the sealing cover and the draining port 12 are tightly sealed, the sealing plate 2 comprises a magnetic plate 21 and an elastic member 22, and the elastic member 22 covers the magnetic plate 21.

And in order to ensure the joint of the top surface of the draining bracket 6 and the inner pot 1, the top surface of the draining bracket 6 is a conical surface so as to be jointed with the bottom of the bulge 13.

The mounting plate is arranged in the draining support 6 in a spanning mode, the center of the mounting plate is bulged to form a sealing sleeve 61, and the sealing sleeve 61 divides a mounting cavity communicated with the outside from the draining channel. The sealing sleeve 61 is sleeved outside the push rod 3 and the piston cavity through the mounting cavity, an elastic part 62 is formed at the upper end of the sealing sleeve 61, an opening is formed at the top end of the elastic part 62, and the push rod 3 extends out of the sealing sleeve 61 from the opening. The push rod 3 forms a sealing plate 32 in the installation cavity, when the push rod 3 rises to jack up the sealing disc 2, the sealing plate 32 abuts against the edge of the opening, and the elastic part 62 is elastically deformed, so that the opening is closed, and rice water is prevented from flowing into the piston cavity. Moreover, in order to ensure the sealing effect of the opening, the elastic portion 62 is corrugated, so that the elastic portion 62 is elastically deformed.

In addition, the top end of the push rod 3 is provided with a push disk 33 to increase the contact area of the sealing disk and the push rod 3 and prevent the push rod 3 and the sealing disk 2 from being dislocated in the pushing process.

Through mutually supporting of constant head tank 11, push rod 3 and waterlogging caused by excessive rainfall support 6 like this, guarantee from the leakproofness of waterlogging caused by excessive rainfall mouth 12 to waterlogging caused by excessive rainfall passageway, set up magnetic closed disk 2 moreover, simple structure, the dead angle is less, the clearance of being convenient for.
