Referring to fig. 1, a cooking appliance, such as an electric pressure cooker, according to an embodiment of the present invention includes a pot body and a pot cover (not shown) covering the pot body, wherein the pot body includes a heat-insulating cover 1, a metal casing 2, a middle plate 3, a base 4, an inner pot 5, and a heater tray assembly (not numbered).

Middle plate 3 is located the top of the pot body, base 4 is located the bottom of the pot body, 2 centre grippings of metal casing are between middle plate 3 and base 4, and heat preservation cover 1 is located the cavity that shell 2, middle plate 3 and base 4 formed jointly, and shell 2 encircles heat preservation cover 1, and interior pot 5 is located heat preservation cover 1, and the heater tray subassembly is located and heat preservation cover 1 bottom and interior between the 5 bottoms of pot for interior pot 5 heats. The whole product frame of the cooking utensil is basically the same as that of a conventional electric pressure cooker, and the main improvement of the electric pressure cooker lies in the grounding structure of the shell 2.

Since the housing 2 is made of metal, in order to prevent the housing 2 from being electrified and causing injury to a user due to electric leakage of some electronic components of the cooking appliance, the housing 2 needs to be grounded. Referring to fig. 2 to 4, the housing 2 is formed with a grounding strip 21 by press molding, and the grounding strip 21 is electrically connected to the heat-insulating cover 1 and fixed to the heat-insulating cover 1. Because the heat preservation cover 1 is grounded, the shell 2 is reliably fixed on the heat preservation cover 1 through the grounding sheet 21 and is electrically connected with the heat preservation cover 1 to realize grounding, the grounding sheet 21 is simple in structure, original redundant materials on the shell 2 are utilized during punch forming, and the manufacturing cost is reduced.

The heat preservation cover 1 is provided with a bottom wall 11 and a side wall 12, and the grounding sheet 21 of the shell 2 is in a thin strip shape, is bent inwards from the shell 2 to extend to the lower part of the bottom wall 11, and is fixed on the bottom wall 11 through a fastening piece 6. The fastener 6 can reliably fix the grounding piece 21, ensure that the grounding piece 21 is in a stable state, and keep the grounding state of the shell 2. In this embodiment, the fastening member 6 is a screw, the bottom wall 11 is provided with a threaded hole (not numbered), the grounding plate 21 is provided with a mounting hole 211, the fastening member 6 passes through the mounting hole 211 to be locked with the threaded hole (not numbered) (see fig. 4), and an anti-rotation washer 61 is further arranged between the fastening member 6 and the grounding plate 21. The mode of threaded connection fixes ground lug 21 simply reliably.

The housing 2 is sprayed before being die cut, with a coating on the outer side 22 and the inner side 23 remaining the original surface, uncoated. Referring to fig. 2 and 3, in fig. 2, the base 4 is removed from the grounding plate 21 for easy observation, the grounding plate 21 is bent inward and downward, and the upper surface 212 of the grounding plate 21 contacting the bottom wall 11 of the heat-insulating cover 1 is a part of the outer side surface 22 with the coating, so that the grounding plate 21 is not directly electrically connected with the heat-insulating cover 1. In this embodiment, the grounding plate 21 is electrically connected to the heat-insulating cover 1 through the conductive fastener 6, the fastener 6 may be a metal screw, the grounding plate 21 is electrically connected to the fastener 6, and the fastener 6 is electrically connected to the heat-insulating cover 1, so that the grounding plate 21 is electrically connected to the heat-insulating cover 1. Therefore, the effect of electrically connecting the shell 2 and the heat preservation cover 1 can be achieved, and the original manufacturing process of the shell 2 is not influenced.

The housing 2 is provided with an opening 24, and the opening 24 may be an opening for embedding the control panel assembly 7, or may be an opening for other functions, such as a heat dissipation hole. The grounding plate 21 extends from the edge of the opening 24, that is, the grounding plate 21 utilizes the originally redundant material when the opening 24 is formed by punching, thereby reducing the manufacturing cost of the product.

The shell 2 is formed by bending a metal sheet into a ring shape, two ends need to be lapped or spliced, and overlapped parts are formed at the two ends during lapping; during splicing, additional connecting pieces cover the joint of the two ends, so that the overlapping or covered part of the ends can be used for forming the grounding plate 21. In another alternative embodiment of the housing 2, as shown in fig. 5, unlike the previous embodiment, the grounding plate 21 is disposed at one end 25 of the two ends 25, and no matter whether the two ends 25 of the housing 2 are overlapped or spliced, the hole left by the grounding plate 21 when the housing 2 is formed can be shielded, and the appearance of the housing 2 is not affected. Specifically, the shell 2 is provided with a notch 26 at the end 25, the grounding piece 21 is bent and extended inwards and downwards from the edge of the notch 26, namely the grounding piece 21 is formed when the end 25 of the shell 2 is directly stamped, the notch 26 is correspondingly formed after the grounding piece 21 is bent, and the notch 26 can be shielded when the two ends 25 are combined, so that the appearance of the shell 2 is not affected.

The pot body also comprises a power line (not shown) and a temperature-sensing cup (not shown), wherein a grounding wire (not shown) of the power line and a grounding wire (not shown) of the temperature-sensing cup are both fixed on the heat-insulating cover 1 and are both electrically connected with the heat-insulating cover 1, so that the heat-insulating cover 1 is grounded, and the shell 2 electrically connected with the heat-insulating cover 1 is also grounded.
