Embodiment approach 1

[0053] The inner pot manufactured according to the inner pot manufacturing method of the present invention can be used in various cooking utensils, such as an electric rice cooker, an electric pressure cooker or other cooking utensils heated by a heating device such as a heating plate or a heating coil. And, the inner pot manufactured according to the inner pot manufacturing method of this embodiment can be applied to a cooking utensil having a steaming layer.

[0054] The following first briefly describes the structures of the inner pot and the steaming layer in the cooking appliance.

[0055] Such as figure 2 As shown, the inner pot 100 may be formed in the shape of a body of revolution, which includes a side wall 120 and a bottom wall 130 connected to the side wall 120 . The upper surface of the inner pot has a circular opening for containing materials to be heated in the inner pot, such as rice, soup, etc., and the edge of the opening extends outwards from the inner pot ...

Embodiment approach 2

[0072] Refer to the following Figure 4-6 A second embodiment of the present invention will be described. For the purpose of simplification, when describing the second embodiment, the description of the same parts as those of the first embodiment is omitted.

[0073] Figure 4 It is a flowchart of the manufacturing method of the inner pot according to the second preferred embodiment of the present invention. Such as Figure 4 As shown, the difference between Embodiment 2 and Embodiment 1 is that the manufacturing method of the inner pot according to this embodiment does not include step S2, and the manufacturing method of the inner pot according to this embodiment also includes after the stretching step S1 Step S5: Roll out concave-convex side wall knurling on the outer surface of the side wall by rolling, and preferably, before the stretching step S1, further include a step S0: Press the concave-convex in the middle of the sheet A plurality of bottom wall knurlings of the...

Embodiment approach 3

[0085] Refer to the following Figure 7-9 A third embodiment of the present invention will be described. For the purpose of simplification, when describing the third embodiment, the description of the same parts as the first embodiment is omitted.

[0086] Figure 7 It is a flowchart of the manufacturing method of the inner pot according to the third preferred embodiment of the present invention. Such as Figure 7 As shown, the difference between Embodiment 3 and Embodiment 1 is that the manufacturing method of the inner pot according to this embodiment does not include step S2, and the manufacturing method of the inner pot according to this embodiment further includes step S6 after step S4 : The CD pattern is turned on the upper surface of the flange of the inner pot by turning.

[0087] It can be understood that the CD pattern is an effect similar to the CD pattern obtained by removing material on the metal surface. In specific applications, the CD pattern can be obtaine...

Abstract

The invention discloses a manufacturing method of an inner pot. The inner pot is used for a cooking utensil. The cooking utensil comprises a steam layer. The top of the steam layer is provided with a steam layer flange. The manufacturing method comprises the following steps: performing stretch forming on a sheet material used for manufacturing the inner pot in order to primarily form the inner pot comprising a side wall and a bottom wall connected to the side wall, wherein the top of the side wall comprises an annular inner pot flange which outwardly extends; pressing a recessed part on the inner pot flange, wherein the recessed part is suitable for placing the steam layer flange and configured in the manner that the steam layer is fixed in a horizontal direction. The inner pot enables the cooking utensil to have a better sealing effect.

Description

technical field [0001] The invention relates to a manufacturing method of an inner pot. Background technique [0002] Existing cooking utensils usually include a cover and a pot body. The pot body usually accommodates an inner pot to facilitate various processing of food, such as steaming and cooking. The cover body is usually provided with a sealing ring. When the cover body is closed on the pot body, the sealing ring in the cover body will be pressed on the inner pot to realize the sealing of the inner pot. The existing inner pot is generally provided with a coating on the inner and outer surfaces, and the part of the inner pot that is in contact with the sealing ring is no exception, but the coating in the coating usually blocks the transfer of heat in the inner pot to the sealing ring, which is not conducive to The heating up of the sealing ring will also cause condensed water to accumulate on the sealing ring. When the cooking process ends and the cover is opened, the ...
