[0052] The utility model provides a cooking utensil, which comprises a pot body and a cover body. The pot body has a cylindrical inner pot storage part. The inner pot can be fixedly arranged at the inner pot storage part, or can be freely placed in the inner pot storage part or taken out from the inner pot storage part to facilitate the cleaning of the inner pot. The inner pot is usually made of metal material and has a circular opening on the upper surface for holding materials to be heated, such as rice, soup, etc. The pot body includes a heating device for heating the inner pot, such as a heating plate, to heat the inner pot.

[0053] It can be understood that the cooking utensil according to the present invention can be an electric rice cooker, an electric pressure cooker or other cooking utensil, and the cooking utensil can have various functions such as cooking porridge in addition to the function of cooking rice.

[0054] The cover has a shape that is substantially corresponding to the pot body. The cover can be opened and closed on the pot body. Specifically, it is pivotally connected to the pot body through a pivot shaft and can freely pivot between a closed position and an open position relative to the pot body around a pivot axis where the pivot shaft is located, so as to facilitate the closing and opening of the pot body. When the cover is closed on the pot body, it covers the inner pot and forms a cooking space between the inner pot and the cover. The cover is usually also provided with a pot mouth sealing ring, which can be made of, for example, a rubber material, and is arranged between the cover and the inner pot to seal the cooking space when the cover is in the closed state.

[0055] like Figure 1 and Figure 2 As shown, the cover body 1 mainly includes an inner lining 2, a removable cover assembly 3 and a face cover assembly 4. The removable cover assembly 3 is detachably arranged on the lower side of the inner lining 2, and the face cover assembly 4 is arranged on the upper side of the inner lining 2 and covers the upper surface and the outer peripheral surface of the inner lining 2. The face cover assembly 4 includes a face cover 41, a main circuit board 42 and a panel 43. The face cover 41 is used to cover the upper surface and the outer peripheral surface of the inner lining 2, and the main circuit board 42 is fixed to the face cover 41 and can be connected to the power board or the control board in the pot body. The panel 43 is connected to the face cover 41 from the upper side of the face cover 41 and the main circuit board 42. A sealant is provided between the face cover 41 and the panel 43 to connect the two. Glue is applied around the periphery of the face cover 41, and glue is applied around the main circuit board 42 to seal the main circuit board 42.

[0056] It should be noted that the directional terms used in this article to describe the various components and parts of the cooking appliance, such as "upper", "lower", "above", "below", "upward", "downward", "upper side", "lower side", etc., are relative to the cooking appliance that is placed horizontally with the cover 1 in the closed state.

[0057] The cover 41 has a first surface F1 and a second surface F2 opposite to the first surface F1 (see Figure 3 ), for the illustrated embodiment, the first surface F1 faces upward and the second surface F2 faces downward, so it can also be said that the first surface F1 of the cover 41 is its upper surface and the second surface F2 is its lower surface. The cover 41 is provided with a main circuit board slot 44 recessed from the first surface F1. The main circuit board 42 is arranged in the main circuit board slot 44. The cover assembly 4 also includes a main wire 45, one end of which is connected to the main circuit board 42, and the other end is connected to the power board in the pot body. The cover 41 is provided with a wire hole 46 (see Figure 5 ), the wire hole 46 is connected to the main circuit board slot 44. The main wire 45 is wired on the side where the second surface F2 of the main circuit board 42 is located through the wire hole 46. In this way, the main wire 45 can be easily wired inside the cover 1 to connect the main circuit board 42 to the power board in the pot body.

[0058] The main wire 45 can be a cable. The wire hole 46 can be coated with sealant or provided with a sealant. Specifically, sealant is applied around the main wire 45 located at the wire hole 46. Alternatively, a sealant can be provided at the wire hole 46, and the main wire 45 passes through the inside of the sealant.

[0059] like Figures 2 to 5 As shown, the face cover assembly 4 also includes a secondary power module 47 and a secondary wire 48. The face cover 41 is also provided with a secondary power module slot 49 recessed from the first surface F1, and the secondary power module 47 is arranged in the secondary power module slot 49. The main circuit board slot 44 is connected to the secondary power module slot 49 via the wire slot 50. And the wire slot 50 is recessed from the first surface F1. The secondary wire 48 is wired in the wire slot 50, and connects the main circuit board 42 and the secondary power module 47, so that the main circuit board 42 supplies power to the secondary power module 47. The secondary power module 47 can be a secondary circuit board or other suitable electrical components. The secondary wire 48 can be a flat wire or an independent wire. In this way, the secondary wire 48 can be wired on the side where the first surface F1 of the face cover 41 is located, which avoids opening a through hole for the secondary wire 48 to pass through at the secondary circuit board and setting a seal at the through hole, thereby reducing the number of times the sealing process is used, making the manufacturing process of the product simpler, improving the sealing reliability, and reducing the cost of materials used for sealing, effectively reducing the production cost of the product.

[0060] Optionally, the secondary wire 48 is a flat wire. The width T of the wire groove 50 is ≥ 2 mm, for example, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, etc. The depth of the wire groove 50 is the same as the depth of the main circuit board groove 44 and / or the secondary power module groove 49. In the illustrated embodiment, the depth of the wire groove 50 is the same as the depth of both the main circuit board groove 44 and the secondary power module groove 49. Optionally, the depth H of the wire groove 50 is ≥ 2 mm, for example, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, etc.

[0061] The cover 41 is provided with at least one auxiliary power module slot 49, wherein the illustrated embodiment schematically shows one auxiliary power module slot 49 and one wire slot 50, and at this time, the number of auxiliary power modules 47 is one. When the number of auxiliary power module slots 49 is at least two, the number of auxiliary power module slots 49 is the same as the number of wire slots 50, and the number of corresponding auxiliary power modules 47 is also the same. Each auxiliary power module 47 is arranged in a corresponding single auxiliary power module slot 49, and is connected to the main circuit board 42 through a corresponding single auxiliary wire 48.

[0062] like Figure 4As shown, the cover 41 is provided with a limiting structure 51, and the auxiliary wire 48 is clamped between the limiting structure 51 and the bottom wall of the wire slot 50. By fixing the auxiliary wire 48 with the help of the limiting structure 51, the auxiliary wire 48 can be kept in the wire slot 50, and the wiring is more neat. An example is, Figure 5 As shown, the limiting structure 51 is a cable tie, which may include a transverse column 52 extending along the width of the cable trough 50 and a vertical column 53 extending along the depth of the cable trough 50. The auxiliary wire 48 is limited in the limiting area formed by the transverse column 52 and the vertical column 53. The limiting structure 51 is simpler, has a good fixing effect on the auxiliary wire 48, and is convenient for production and manufacturing.

[0063] The limiting structure 51 is formed integrally with the face cover 41. The limiting structure 51 and the face cover 41 are an integral component, which simplifies the overall structure of the face cover 41, omits the installation process of the limiting structure 51, and facilitates the production and manufacturing of the face cover assembly 4. Specifically, the horizontal column 52 extends from the first side wall 54 of the wire trough 50, there is a first gap between the vertical column 53 and the second side wall 55 of the wire trough 50, and there is a second gap between the vertical column 53 and the bottom wall of the wire trough 50, and the auxiliary wire 48 is wired in the limiting area through the first gap and the second gap. The assembly process of the auxiliary wire 48 is easier to operate, which improves the assembly efficiency.

[0064] Further, in the solution with the limiting structure 51 in the wire trough 50, the width T of the wire trough 50 is ≥ 6 mm, for example, a suitable value such as 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, etc.

[0065] The wire hole 46 is provided in the main circuit board slot 44 and is adjacent to the wire slot 50. In the illustrated embodiment, the auxiliary power module slot 49 corresponds to the corner of the main circuit board slot 44, and the wire hole 46 is provided at the corner of the main circuit board slot 44. Thus, the wiring of the main wire 45 and the auxiliary wire 48 is facilitated, and the wiring efficiency is improved.

[0066] Unless otherwise defined, the technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art of the present invention. The terms used herein are only for describing specific implementation purposes and are not intended to limit the present invention. The features described herein in one embodiment may be applied to another embodiment alone or in combination with other features, unless the feature is not applicable or otherwise specified in the other embodiment.
