A heating base 100 of a food digester according to an embodiment of the invention is described below with reference to fig. 1-14.

As shown in fig. 1-11, a heating base 100 of a food cooker according to an embodiment of the present invention includes: a liner 10, a heating member 20 and a sealing member 30.

The inner container 10 defines a heating cavity with an open top, the bottom of the inner container 10 is provided with an opening 11, the heating element 20 is arranged at the bottom of the inner container 10, the heating element 20 seals the opening 11 so as to heat the inner container 10, the sealing element 30 is arranged between the inner container 10 and the heating element 20, and the sealing element 30 is respectively matched with the inner container 10 and the heating element 20 in a sealing way.

According to the utility model discloses food boiler's heating base 100 through set up sealing member 30 between inner bag 10 and heating member 20, can make sealing member 30 and the sealed cooperation of inner bag 10 and make sealing member 30 and the sealed cooperation of heating member 20 to strengthen the sealing reliability between inner bag 10 and the heating member 20, prevent to heat base 100 and take place the problem of leaking.

According to some embodiments of the present invention, the sealing member 30 extends along the circumferential direction of the opening 11, so that the gap between the inner container 10 and the heating member 20 in the circumferential direction of the opening 11 is sealed by the sealing member 30, and the water in the inner container 10 is prevented from leaking out from the opening 11.

In some embodiments, the seal 30 forms a circular or square ring shape extending along the circumference of the opening 11. That is, the sealing member 30 may form a closed ring extending in the circumferential direction of the opening 11, if the opening 11 is formed in a circular shape, the sealing member 30 may form a circular ring extending in the circumferential direction of the circular shape, and if the opening 11 is formed in a square shape, the sealing member 30 may form a square ring extending in the circumferential direction of the square shape, that is, the shape of the sealing member 30 may correspond to the shape of the opening 11. Of course, the shape of the sealing member 30 may not correspond to the shape of the opening 11, for example, the opening 11 may be formed in a circular shape, and the sealing member 30 may be formed in a square shape surrounding the sealing member 30.

The applicant found that when the opening 11 is formed in a circular shape, if the diameter of the opening 11 is too small, bubbles push water to automatically trip the heating member 20, and if the diameter of the opening 11 is too large, the sealing property between the inner container 10 and the heating member 20 is difficult to be ensured, and a water leakage problem is likely to occur, so that the diameter of the opening 11 is controlled to be 40mm to 60mm, for example, the diameter of the opening 11 may be 40mm, 45mm, 50mm, 55mm, or 60 mm.
