Shown in referring to Figure 1 and Figure 2, for according to the sectional view of the cooking apparatus of the application one embodiment, the cooking apparatus Including pot cover 1, pot body 2 and sealing ring 3, for sealing the gap between the pot cover 1 and pot body 2.In the present embodiment, described Cooking apparatus is electric pressure cooking saucepan, and the pot cover 1 generally includes the cover (not labeled) that ecto-entad sets gradually, lining lid (is not marked Number) and inner cover 10, the pot body includes interior pot and the cooker body (not labeled) for accommodating the interior pot, and the inner cover 10 and the interior pot are total With a cooking cavity is formed, the sealing ring 3 is fixed to the bottom side of the inner cover 10, and seals the inner cover 10 and the interior pot pot Gap between.

A retainer plate 4 is additionally provided on the inner cover 10, for the sealing ring 3 to be fixed to the inner cover 10.Fig. 2 is shown Be the inner cover 10 of the pot cover 1, sealing ring 3 and retainer plate 4 mated condition, Fig. 3 is the partial enlarged view of Fig. 2.In described Lid 10 is equipped with several mounting holes 101, and screw (not shown) passes through the retainer plate 4 along first direction and is fixed to the mounting hole 101, which is fixed on the inner cover 10.

The top 30 of the sealing ring 3 is equipped with the rib 31 of upward projection, and the retainer plate 4 and the inner cover 10 are along second Direction grips the mode of the rib 31, which is fixed on inner cover 10 altogether with the retainer plate 4.Wherein Two directions are different from first direction.In use, the sealing ring 3 is by the high-temperature gas in the cooking cavity for the cooking apparatus Influence can generate dilatancy.The deformation of the rib 31 can squeeze the corresponding side of retainer plate 4 and inner cover 10 positioned at its two sides Wall.But due to this power be in a second direction, and the assembly orientation of screw be along be different from the second direction first direction, So the deformation of the rib 31 not will cause the loosened screw, it is ensured that the retainer plate 4 and the sealing ring 3 are reliably fixed, Ensure that the sealing performance of the sealing ring 3, the normal culinary art of the cooking apparatus.

Preferably, aforementioned first direction is vertical direction, is also believed to up and down direction, and second direction is then lateral side To being also believed to left and right directions.

The generally circular sheet of the inner cover 10, including being located at the main body 11 at middle part and around the periphery of the main body 11 setting Edge 12.The main body 11 is recess setting relative to the circumferential edges 12.Fig. 4 only shows the inner cover because being cross-sectional view 10 a part.The circumferential edges 12 are equipped with roof 121 and connect the first side wall at 11 edge of the roof 121 and the main body 122.Aforementioned mounting hole 101 is formed on the roof 121.Aforementioned screw, which is from bottom to top assembled, is fixed on institute for the retainer plate 4 The downside of roof 121 is stated, the rib 31 of the sealing ring 3 is then by the retainer plate 4 and the first side wall at left and right sides of it 122 grip jointly.The first side wall 122 and retainer plate 3 are squeezed when 31 dilatancy of rib, as previously mentioned, because of this The direction of power not in the assembly orientation of screw, therefore, which not will cause the loosening of screw.

The circumferential edges 12 are additionally provided with the second sidewall 123 positioned at outside, the roof 121, the first side wall 122 and second Side wall 123 is collectively formed a circle holding tank (not labeled), the bottom opening setting of the holding tank, the retainer plate 4 and described close The rib 31 of seal 3 is fixed in the holding tank.

In conjunction with shown in Fig. 4 and Fig. 5, it is preferred that the retainer plate 4 is equipped with medial surface 41 and lateral surface 42, the medial surface 41 are equipped with groove 43, and the outside of the rib 31 of the sealing ring 3, which is equipped with, projects outwardly convex ribs 32, and the convex ribs 32 are for being caught in this In groove 43.32 groups of the convex ribs are entered in the groove 43 and sealing ring 3 is fixed on the retainer plate 4 so can first pass through, Enter convex ribs 32 with 4 groups of retainer plate in the holding tank of the inner cover 10, finally again with aforementioned screw by the retainer plate 4 It is fixed on the roof 121 of the inner cover 10.It please notes, which is not passed through the sealing ring 3, which is to rely on The retainer plate 4 and 10 the first side wall 122 of the inner cover to the clamping of its convex ribs 32 and fixation.The convex ribs 32 with it is described recessed The interworking design of slot 43 can be convenient the fixation and assembling of the sealing ring 3.

After being completed, the lateral surface 42 of the retainer plate 4 against the second sidewall 123 of the inner cover 10 medial surface, That is, medial surface of the retainer plate 4 out against second sidewall 123.4 bottom of retainer plate is additionally provided with step surface, with can Upwards against the bottom surface of the second sidewall 123 of the inner cover 10.The top 31 of the sealing ring 3 is upwards against the retainer plate 4 Bottom surface.The sealing ring 3, retainer plate 4 and 10 three of inner cover closely fit together.

Preferably, the inner cover 10 is stainless steel material, and the sealing ring 5 is silica gel material, and the retainer plate 4 is plastic cement Material.Therefore the retainer plate 4 and inner cover 5 be not affected by temperature substantially, own vol will not change, it is ensured that original Assemble fixed reliability.

As shown in connection with fig. 1, the sealing ring 3 is equipped with outer lip 33 and lower lip 34, is bonded the pot edge of the interior pot respectively The upper surface at place and interior sidewall surface are sealed the gap between the inner cover 10 and the interior pot.

The foregoing is merely the preferred embodiments of the application, not to limit the application, all essences in the application Within mind and principle, any modification, equivalent substitution, improvement and etc. done be should be included within the scope of the application protection.
