As shown in fig. 1 to 17, the cooking appliance includes an upper cover assembly 10 and a pot body assembly, the upper cover assembly 10 is openably and closably covered on the pot body assembly, the upper cover assembly 10 includes a face cover 20, a liner 30 and a pot cover 40, wherein the liner 30 is located below the face cover 20, and the liner 30 has a liner sinking platform 31 recessed to a side away from the face cover 20; the lid 40 is mounted below the liner 30 and the liner sink 31 is adapted to receive at least one structural member.

By forming the inner liner sunken platform 31 on the inner liner 30 of the upper cover assembly 10, a part of structural members in the upper cover assembly 10 can be mounted on the inner liner sunken platform 31, so that the distance between the area of the inner liner 30 except the inner liner sunken platform 31 and the face cover 20 is reduced, and the thickness of the upper cover assembly 10 in the vertical direction is reduced, so that the upper cover assembly 10 is not so thick and is more light and thin, and the aesthetic property of the upper cover assembly 10 is improved. Because the inner liner 30 has an opening facing the lid 40, and the inner liner sinking platform 31 is formed by the inner liner 30 being recessed to the side far from the face cover 20, a certain gap is provided between the inner liner sinking platform 31 and the lid 40 to prevent the inner liner sinking platform 31 from obstructing the rotation of the lid 40.

Specifically, the distance H1 between the inner liner and the lid 40 is greater than or equal to 3 mm and less than or equal to 7 mm, so that the thickness of the lid assembly 10 can be reduced without hindering the rotation of the lid 40.

As shown in fig. 4, the sinking platform depth D1 of the liner sinking platform 31 is not less than 3 mm and not more than 20 mm.

As shown in fig. 4, a distance H2 between the top surface of the liner 30 and the surface of the upper surface non-projecting structure portion of the face cover 20 is 15 mm or more and 20 mm or less. The arrangement ensures that a certain gap is reserved between the face cover 20 and the lining 30 so as to be used for installing some structural members, effectively limits the distance between the face cover 20 and the lining 30, and avoids the phenomenon that the whole thickness of the cooker body assembly is too thick due to too large size of the position. It should be noted that the thickness of the structural members must not be too thick to exceed 20 mm, which would increase the thickness of the entire cover assembly 10 and affect the aesthetic appearance of the cover assembly 10.

As shown in fig. 4 to 6, when the lid 40 is installed in the cooking appliance, the lid sinking platform 41 is formed by recessing the lid 40 to the side away from the liner 30, and the lid sinking platform 41 is used to avoid the liner sinking platform 31. When the inner liner 30 and the pot cover 40 are assembled together, the inner liner sinking platform 31 is located right above the pot cover sinking platform 41, so that the pot cover sinking platform 41 can reasonably avoid the inner liner sinking platform 31, and the pot cover 40 is prevented from generating motion interference with the inner liner sinking platform 31 in the rotating process.

Specifically, the area of the pot cover settling platform 41 is larger than or equal to the area of the inner liner settling platform 31, so that the inner liner settling platform 31 does not hinder the rotation of the pot cover 40 without making the top surface of the pot cover 40 lower than the bottom surface of the inner liner settling platform 31.

In addition, the distance H4 between the bottom surface of the inner liner sinking platform 31 and the sinking platform surface 411 of the pot cover sinking platform is more than or equal to 3 mm and less than or equal to 7 mm. Thus, on the premise of ensuring the lightness and thinness of the upper cover assembly, partial structural members can be arranged between the inner liner sinking platform 31 and the pot cover sinking platform 41, enough installation space is reserved for the installation of the structural members, and the functions of the upper cover assembly such as air exhaust and the like can be ensured.

Thus, the gap between the lid 40 and the liner 30 is further reduced, the thickness of the lid assembly 10 can be effectively reduced, the lid assembly 10 is more light and thin, and the aesthetic property of the lid assembly is enhanced.

As shown in fig. 5, a distance H5 between the circumferential inner side wall of the pot cover settling platform 41 and the circumferential outer side wall of the inner liner settling platform 31 is 1 mm or more and 4 mm or less. The arrangement can ensure that the liner sinking platform 31 does not contact and rub with the pot cover sinking platform 41, ensure that the liner 30 does not influence the rotation of the pot cover 40, effectively avoid movement interference, and reduce the thickness of the upper cover assembly 10 as much as possible.

As shown in fig. 5, the circumferential side wall of the inner liner settling platform 31 extends obliquely inward in a direction away from the face cover 20. The circumferential side wall of the pot lid settling platform 41 extends obliquely inward in a direction away from the face lid 20. Or the openings of the inner liner sinking platform 31 and the pot cover sinking platform 41 are flaring. The opening of the inner liner settling platform 31 is flared to facilitate installation of the structural member in the inner liner settling platform 31, and to provide a larger installation space for the structural member. The opening of the pot lid sinking platform 41 is flared to facilitate a part of the inner liner sinking platform 31 to sink into the pot lid sinking platform 41, which is beneficial to reducing the thickness of the lid assembly 10. Meanwhile, the opening of the pot cover sinking platform 41 is in a flaring shape, so that the interference of the pot cover 40 with the lining 30 during movement can be effectively avoided, and the movement reliability of the pot cover 40 is ensured.

In another embodiment, not shown, the circumferential side wall of the inner liner table 31 is vertical, i.e. the opening of the inner liner table 31 is not flared but vertical. The circumferential side wall of the pot cover sinking platform 41 extends obliquely inward along the direction away from the face cover 20, that is, the opening of the pot cover sinking platform 41 is flared, and a part of the inner liner sinking platform 31 sinks into the region of the pot cover sinking platform 41, which also reduces the thickness of the upper cover assembly 10, so that the upper cover assembly 10 is lighter and thinner.

The exhaust rod base 52 is installed on the pot cover sinking platform 41 through the exhaust rod base fixing frame 53, the exhaust rod base is located at the edge of the exhaust pipe 51, and a certain gap is formed between the exhaust rod base 52 and the exhaust pipe 51 to avoid affecting the exhaust pipe 51. The exhaust lever 54 will lift up part of the structure on the face cover 20 under the action of the solenoid valve 150 to exhaust the exhaust pipe 51.

As shown in fig. 8, the upper cover assembly 10 further includes at least one of a rotary rod mounting part 120, a temperature measuring device housing part 100, and a cold air valve passage 110, and at least one of the rotary rod mounting part 120, the temperature measuring device housing part 100, and the cold air valve passage 110 is disposed in the liner settling platform 31. In the present embodiment, the inner liner settling platform 31 is installed with the rotating rod installation part 120, the temperature measuring device accommodation part 100 and the cold air valve passage 110, so that the height of the upper cover assembly 10 increased by installing the rotating rod installation part 120, the temperature measuring device accommodation part 100 and the cold air valve passage 110 is reduced, and the thickness of the upper cover assembly 10 is further reduced.

As shown in fig. 7, the upper cover assembly 10 further includes a rotating bar 90, and the rotating bar 90 is mounted on the inner liner settling platform 31 to prevent the rotating bar 90 from increasing the thickness of the upper cover assembly 10. This allows a portion of the turn bar 90 to be within the liner sinkers 31 to reduce the added thickness of the lid assembly 10 by the turn bar 90. The rotating rod mounting part 120 is arranged in the inner liner sinking platform 31, so that one part of the rotating rod 90 can enter the inner liner sinking platform 31, and the other part of the rotating rod 90 extends out of the inner liner sinking platform 31, the thickness of the rotating rod 90 between the inner liner 30 and the face cover 20 is indirectly reduced, the thickness of the upper cover assembly 10 in the vertical direction is reduced, the upper cover assembly 10 is not heavy, the weight is reduced, and the attractiveness of the upper cover assembly 10 is improved.

As shown in fig. 8, the lower surface of the inner liner sinking platform 31 has a housing portion 311 protruding toward one side of the face cover 20, the housing portion 311 is disposed corresponding to the safety valve 70 to provide a space for the movement of the safety valve 70, the housing portion 311 is located in the inner liner sinking platform 31, and the height of the housing portion 311 does not exceed the plane of the top opening of the inner liner sinking platform 31. The receiving portion 311 is formed by the lower surface of the inner liner settling platform 31 rising toward the surface cover 20 to form a certain relief space, which provides a certain relief space for the movement of the safety valve 70. When the pressure inside the cooking utensil is higher than the safety pressure, some parts in the safety valve 70 can be popped out, so that the pressure of the cooking utensil is relieved, the pressure relief protection is formed on the cooking utensil, and the phenomenon that the pressure inside the cooking utensil is too high and the explosion damages people is avoided. The receptacle 311 is arranged to allow certain parts of the safety valve 70 to pop out to prevent the liner sink 31 from preventing the safety valve 70 from venting. The containing portion 311 is located in the inner liner sunken stage 31 to prevent the containing portion 311 from increasing the thickness of the upper cover assembly.

As shown in fig. 5, the face cover 20 has a face cover settling platform 21 recessed toward one side of the inner liner 30, and the upper cover assembly 10 further includes a steam box 130, the steam box 130 being disposed at the face cover settling platform 21. The provision of the face cover settling platform 21 effectively prevents the steam box 130 from being mounted on the face cover 20 to increase the thickness of the upper cover assembly 10.

Optionally, the distance H3 between the bottom surface of the top cover sinking platform 21 and the top surface of the inner lining 30 is greater than or equal to 5 mm and less than or equal to 15 mm, which provides an installation space for installing some structural members between the bottom surface of the top cover sinking platform 21 and the inner lining 30.

As shown in fig. 9, the rotating rod mounting part 120 includes a main body part 121 and a connecting part 122, the main body part 121 is annular, the connecting part 122 is located at the center of the annular shape and is spaced from the main body part 121, and an area between the main body part 121 and the connecting part 122 is a receiving recess 123; the rotating lever 90 has a fitting projection 93 projecting toward the rotating lever mounting part 120, and the fitting projection 93 is fitted into the accommodation recess 123. The engagement protrusion ring 93 of the rotation rod 90 is coupled to the coupling portion 122 and positioned in the receiving recess 123 such that the engagement protrusion ring 93 of the rotation rod 90 is positioned in the inner liner settling plate 31, thereby reducing the thickness of the upper cover assembly 10.

As shown in fig. 12, the outer circumferential surface of the fitting projection ring 93 is inclined inwardly in a direction away from the face cover 20. This arrangement facilitates the installation of the rotary rod 90 at the rotary rod installation portion 120, so that the fitting protrusion ring 93 is more tightly connected to the connection portion 122, and the rotation of the rotary rod 90 is not affected.

As shown in fig. 9, the rotating rod mounting part 120 includes a plurality of reinforcing triangular rib plates 124, the plurality of reinforcing triangular rib plates 124 are arranged at intervals around the annular inner annular surface, and two right-angle plates of each reinforcing triangular rib plate 124 are respectively connected with the counter surface of the inner lining counter 31 and the annular inner annular surface, and the outer annular surface of the matching convex ring 93 is in clearance fit with the reinforcing triangular rib plates 124. The arrangement of the reinforcing triangular rib plate 124 increases the structural strength of the rotating rod mounting part 120, and the reinforcing triangular rib plate is matched with the matching convex ring 93 on the rotating rod 90 to limit the rotating rod 90 to swing. And the clearance between the outer ring surface of the matching convex ring 93 and the reinforcing triangular rib plate 124 can prevent the rotating rod 90 from rubbing against the reinforcing triangular rib plate 124 in the rotating process. However, the gap should not be too large, which could cause the rotation lever 90 to rotate unstably.

As shown in fig. 11 to 13, the rotating lever 90 includes a main body 91 and a swing arm 92, wherein a fitting convex ring 93 is provided on one side of the main body 91 facing the rotating lever mounting portion 120, the swing arm 92 is connected to the main body 91, the swing arm 92 is higher than the fitting convex ring 93 in the axial direction of the rotating lever 90, and at least one of a suspension post mounting hole 921, a clasp triggering portion 922 and a magnetic steel mounting portion 923 is provided on the swing arm 92.
