Description

Technical Field

[0001] This utility model specifically relates to an electric slow cooker with uniform and rapid heating function. Background Technology

[0002] Electric slow cookers are common cooking appliances in people's daily lives. An electric slow cooker consists of a heating element and a ceramic inner pot housed in the heating element. The heating element includes a heating plate located at the bottom of the ceramic inner pot. The heating plate is used to generate heat and transfer the heat to the bottom surface of the ceramic inner pot.

[0003] However, during use, the heating plate only heats the bottom surface of the ceramic inner liner. The heat transfer is limited by the nature of the ceramic inner liner, resulting in poor heat transfer and uneven heating of the ceramic inner liner, which can easily cause damage to the ceramic inner liner. Summary of the Invention

Therefore, one objective of this invention is to provide an electric slow cooker with a uniform and rapid heating function, which enables uniform and rapid heating of the ceramic inner pot surface and extends the service life of the ceramic inner pot.

[0006] Furthermore, the outer surface of the pot body is provided with a handle, and the surface of the handle is arc-shaped.

[0007] Furthermore, the surface of the handle is provided with anti-slip textured surfaces.

[0008] Furthermore, the surface of the heating convex disc is provided with raised texture.

[0009] Specifically, the raised pattern is circular.

[0010] Specifically, the mica sheet has a hollow space in the middle.

[0011] Furthermore, a fixing screw is installed at the middle position of the heating cam, and a temperature controller and a nut are installed on the fixing screw. The nut is screwed onto the fixing screw and fixes one side of the temperature controller.

[0012] Specifically, the temperature sensing end of the temperature controller is placed at the bottom surface of the heating cam or at the bottom surface of the mica sheet.

[0013] Specifically, the height of the heating cam is 2cm to 5cm.

[0014] The beneficial effects of this utility model are: this structure heats the surface of the ceramic inner liner by means of mica sheet heating on the heating convex plate, and works with the metal inner cavity to uniformly transfer heat, thereby achieving uniform and rapid heating of the surface of the ceramic inner liner and improving the service life of the ceramic inner liner.

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0024] The following is for reference. Figures 1 to 5According to an embodiment of the present invention, an electric slow cooker with uniform and rapid heating function includes a pot body 1, a metal inner cavity 4 inside the pot body 1, a ceramic inner pot 2 placed inside the metal inner cavity 4, a heating convex plate 401 at the middle position of the bottom surface of the metal inner cavity 4, a mica sheet 5 on the bottom surface of the heating convex plate 401, a heating bottom surface 201 on the bottom surface of the ceramic inner pot 2, a convex ring 202 on the edge of the heating bottom surface 201, and the upper surface of the heating convex plate 401 is placed at the heating bottom surface 201, and the heating convex plate 401 is located inside the convex ring 202.

[0025] This structure uses mica sheets 5 to heat the heating cam 401, and works in conjunction with the metal inner cavity 4 to uniformly transfer heat, achieving uniform and rapid heating of the surface of the ceramic inner liner 2, and extending the service life of the ceramic inner liner, avoiding the disadvantage of heat concentration on the bottom surface of the ceramic inner liner 2. Furthermore, the metal inner cavity 4 and the heating cam 401 are integrally formed, and the shape of the heating cam 401 is formed by stamping. The heat from the heating cam 401 can be transferred along the metal inner cavity 4.

[0026] The shape of the heating convex plate 401 is adapted to the shape of the heating bottom surface 201. The heating convex plate 401 can evenly heat the heating bottom surface 201. Together with the convex ring 202, it further restricts the position of the ceramic inner liner 2, preventing it from shifting arbitrarily. The lid 3 is placed on the ceramic inner liner 2.

[0027] The outer surface of the pot body 1 described in this structure is provided with a handle 101. The surface of the handle 101 is arc-shaped, which is conducive to the hand gripping the handle 101. The surface of the handle 101 is provided with anti-slip raised texture 102. The anti-slip raised texture 102 serves to prevent slipping.

[0028] The surface of the heating cam 401 in this structure is provided with raised textures, which are circular. These textures help to better contact the bottom surface of the ceramic inner liner 2.

[0029] The mica sheet 5 in this structure has a hollow position 501 in the middle. The hollow position 501 serves to prevent air leakage and facilitates the passage of the fixing screw 601 through the hollow position 501.

[0030] In this structure, a fixing screw 601 is installed at the center of the heating cam 401. A thermostat 6 and a nut 602 are mounted on the fixing screw 601. The nut 602 is screwed onto the fixing screw 601 and fixes one side of the thermostat 6. The thermostat 6 detects temperature and outputs temperature parameters to a control board. The control board is connected to the mica sheet 5 and controls the working state of the mica sheet 5. A hole is provided on the side of the thermostat 6 through which the fixing screw 601 passes, thus limiting the position of the thermostat 6. In this structure, the temperature sensing end of the thermostat 6 is placed at the bottom surface of the heating cam 401 or at the bottom surface of the mica sheet 5 to detect the surface temperature of the heating cam 401 and the mica sheet 5, preventing overheating. The height of the heating cam 401 in this structure is 2cm to 5cm, which facilitates contact between the heating cam 401 and the ceramic inner liner 2.

[0031] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
