The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

As shown in fig. 1 to 3, a multi-bladder electric cooker according to a preferred embodiment of the present utility model includes a cooker body 1 and a cooker cover 2 hinged to the cooker body 1. The pot 1 is fitted with a hinge assembly 12 connected to the pot lid 2 and at least three inner containers 11 having openings 111. The hinge assembly 12 includes a plurality of hinge portions, and the number of hinge portions is the same as that of the inner containers 11, and each hinge portion corresponds to one inner container 11. The number of the pot covers 2 corresponds to the number of the inner containers 11, namely, each pot cover 2 is connected with one inner container 11 and is used for opening and closing the opening 111 of the inner container 11. Specifically, the pot cover 2 can be hinged to the corresponding hinge portion of the pot body 1 through the hinge shaft 21, so that the pot cover 2 can rotate around the hinge shaft 21 to open and close the opening 111 of the inner container 11.

With further reference to fig. 5 and 6, the hinge assembly 12 includes a second hinge 17 at the middle of the pot 1 and a first hinge 16 at both sides of the second hinge 17. The first hinge 16 is preferably integrally formed with at least a portion of the pot 1. A pair of first hinge parts 16 are symmetrically provided at both sides of the second hinge part 17 along the axis of the pot body 1. The first hinge part 16 includes a first connection part 162 integrally formed with the pot body 1 and a first hinge cover 161 integrally formed with the pot body 1. The first connecting portion 162 is integrally formed with the first hinge cover 161 so that the first hinge portion 16 forms a unitary structure, reducing the number of parts of the first hinge portion 16; in addition, the first hinging part 16 and the cooker body 1 are integrally formed, so that the number of parts of the multi-container electric cooker can be further reduced, the structure of the first hinging part 16 and the cooker body 1 which are integrally formed can also avoid the generation of assembly gaps when the independently arranged parts are assembled, and the later maintenance of the electric cooker is facilitated; meanwhile, the first hinge part 16 and the cooker body 1 are integrally formed, and gaps generated during connection of the first hinge part and the cooker body can be removed, so that the whole appearance of the electric cooker is more attractive.

With further reference to fig. 8, the first connection portion 162 includes a first shaft hole wall 165 and a second shaft hole wall 163 adjacent to both ends of the first hinge cover 161, and the first shaft hole wall 165 and the second shaft hole wall 163 are preferably integrally formed with the first hinge cover 161. The first shaft hole wall 165 is provided with a first shaft hole 1651, and the second shaft hole wall 163 is provided with a second shaft hole 1633; the first connecting portion 162 is hollow and has a first passage 164 formed therein to sequentially penetrate through the first shaft hole wall 165 and the second shaft hole wall 163, and both ends of the first passage 164 are respectively communicated with the first shaft hole 1651 and the second shaft hole 1633. The first shaft hole wall 165 is far from the middle of the pot body 1 than the second shaft hole wall 163, and the hinge shaft 21 can penetrate into the first channel 164 from the first shaft hole 1651 of the first shaft hole wall 165 and out through the second shaft hole 1633 so that the hinge shaft 21 is hinged to the first hinge portion 16. The hinge shaft 21 is penetrated from the first shaft hole 1651 far away from the first shaft hole wall 165 in the middle of the cooker body 1, so that the hinge shaft 21 can be penetrated from the outer side of the electric cooker when being installed, and the installation of the hinge shaft 21 is facilitated.

Further, the second shaft hole wall 163 includes a first sub-wall 1631 and a second sub-wall 1632 that are staggered with each other, and the second sub-wall 1632 is disposed close to the first shaft hole wall 165 with respect to the first sub-wall 1631.

The mode that adopts first half hole 1634 and second half hole 1635 to form second shaft hole 1633 can effectually reduce the processing degree of difficulty of first articulated portion 16, because second shaft hole 1633 is the side opening, and the mode that the mould processed the side opening is usually to add side core pulling mechanism shaping side opening (this is prior art, and will not be repeated here), and second shaft hole wall 163 is close to a pot body 1 middle part and is less with the interval of other structures that pot body 1 middle part set up, does not have sufficient space to place side core pulling mechanism when leading to the mould shaping, is unfavorable for the processing of second shaft hole 1633. The two staggered first half holes 1634 and second half holes 1635 are adopted, so that the die can respectively process the first half holes 1634 and the second half holes 1635 through the upper and lower molding blocks (the prior art is omitted herein), and the processing difficulty of the first hinge portion 16 can be greatly reduced.

The first shaft hole wall 165 may be provided as a single wall, and the first shaft hole 1651 is formed on the single wall; in addition, as another embodiment, the first shaft hole wall 165 may be configured as the second shaft hole wall 163 with the first sub-wall 1631 and the second sub-wall 1632.
