[0002] The electric hot pot is a modern cooker that uses a composite bottom welding process and a composite ground welding process. It has high thermal efficiency, long service life, and complete functions. It can be used for frying, deep-frying, steaming, boiling, shabu-shabu, stewing, simmering, braising, etc. It can not only cook food, but also keep it warm. It is clean and hygienic to use, has no radiation, saves time and effort, and is one of the indispensable tools for modern housework.

[0003] Electric hot pots and cookware are usually designed as separate parts. The heating plate inside the electric hot pot is in contact with the cookware to heat the cookware. The effective positioning between the separate cookware and the heating plate can not only enhance the cooking experience but also improve cooking safety.

[0026] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0027] The same parts are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings, and the words "bottom" and "top", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. Specific embodiment one;

[0029] As shown in the figure, a bowl-shaped heating plate comprises a heating plate body 1 with a horizontal surface, an electric heating coil 3 is arranged inside the heating plate body 1, and an annular positioning ring 2 is arranged along the outer peripheral side of the surface of the heating plate body 1. The inner wall of the positioning ring comprises a positioning step surface 201 connected to the bottom of the heating plate, and an opening inclined surface 202 located above the positioning step surface 201. The positioning ring 2 and the heating plate body 1 are both made of metal with good thermal conductivity.

[0030] When cooking, when the pot is placed on the surface of the heating plate, the top of the pot is made into a trumpet-shaped opening through the opening inclined surface 202, so that the pot can be slid into the inside of the positioning ring 2 and the bottom of the pot can finally enter the positioning step surface 201. The positioning step surface 201 can be used to position the bottom of the pot to ensure the stability between the pot body and the heating plate during cooking, prevent the pot from shifting and affecting the cooking experience, and the positioning ring 2 is covered on the bottom of the side wall of the pot body to further improve the heating effect.

[0031] The positioning ring 2 is detachably fixedly connected to the heating plate body 1. The lower surface of the positioning ring 2 is uniformly and integrally formed with four plug-in parts 4 along its circumferential direction. The surface of the heating plate body 1 is provided with four plug-in slots 5 for the plug-in parts 4 to be plugged and fixed. During production and processing, positioning rings 2 of different specifications or shapes are installed according to different cookware, so that the heating plate body 1 and the positioning ring 2 are processed separately during production. At a later stage, the positioning ring 2 and the heating plate only need to be fixedly connected through the plug-in parts 4, so that heating plates suitable for different cookware can be produced, which effectively improves production efficiency and reduces production costs.

[0032] A limit ring 6 is provided on the lower surface of the positioning ring 2 along its circumferential direction, and a limit groove 7 for inserting the limit ring 6 is provided on the surface of the heating plate body 1, further improving the stability of the connection between the positioning ring 2 and the heating plate body 1. Specific embodiment 2:

[0034] An electric hot pot using the heating plate includes a base 8 and a shell 9 arranged on the base 8, a reflector 10 is fixedly installed above the base 8, and the heating plate body 1 is arranged in the reflector 10. A plurality of fixing columns 11 are arranged along the circumferential direction of the bottom of the heating plate body 1, and a threaded hole is opened at the bottom of the fixing column 11. A plurality of screw holes 12 matching the threaded holes are opened at the bottom of the reflector 10, and a first bolt (not shown in the figure) is arranged in the screw hole 12 and is threadedly connected in the threaded hole to fix the heating plate body 1 and ensure its stability during cooking.

[0035] A plurality of positioning members 13 are evenly arranged between the reflector 10 and the base 8 along the circumferential direction, the positioning members 13 include a positioning block 1301, a positioning rod 1302 is arranged at the bottom of one end of the positioning block 1301, a limiting column 14 is arranged on the surface of the base 8 and a positioning groove for inserting the positioning rod 1302 is opened, a second bolt (not shown in the figure) is arranged in the positioning rod 1302 to be fixedly connected to the limiting column 14, a connecting column 1303 is arranged on the other end surface of the positioning block 1301, a third bolt (not shown in the figure) is arranged at the bottom of the connecting column 1303 to be fixedly connected to the reflector 10, and the positioning member 13 is used to fix the reflector 10.

[0036] A plurality of limit heads 1304 are disposed on the surface of the connection column 1303 , and a limit hole 15 for inserting the limit heads 1304 is opened on the lower surface of the reflector 10 , so as to further improve the stability of the reflector 10 after installation.

[0037] A plurality of positioning ribs 16 are evenly arranged on the top of the inner surface of the reflector 10 along its circumferential direction, so that the outer wall of the cookware abuts against the positioning ribs 16. The positioning ribs 16 are made of heat-resistant material to support and position the cookware and prevent the surface of the cookware from completely fitting against the reflector 10, thereby affecting the service life of the reflector 10.

[0038] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
