Description

Technical Field

[0001] This utility model relates to the field of electric slow cooker technology, and in particular to a heating and fixing structure for an electric slow cooker. Background Technology

[0002] Traditional electric slow cookers have a heating element at the bottom of the inner pot, which contains a heating container. The heating element heats the food inside the container. The heating element is either welded to the bottom of the inner pot or integrally formed by die casting. The drawbacks of these two methods are that if the heating element is damaged, it is difficult to repair or replace. Also, if the inner pot is made of aluminum, it is difficult to weld to the heating element, and it can generally only be integrally formed by die casting.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this utility model is to provide a heating and fixing structure for an electric slow cooker that is simple in structure, easy to maintain and replace, easy to assemble and disassemble, has high heat transfer efficiency, and is highly practical, so as to overcome the shortcomings of the prior art.

[0005] A heating element fixing structure for an electric slow cooker designed for this purpose is characterized by: comprising... An inner pot and a heating element, wherein the heating element is disposed at the bottom of the inner pot; A fixing plate is provided between the fixing plate and the inner pot, and the fixing plate is fixed to the bottom of the inner pot through the fixing plate. The heating element is pressed between the bottom of the inner pot and the fixing plate.

[0006] The mounting plate is provided with a receiving groove, the shape of which matches the shape of the heating element, and the heating element is placed inside the receiving groove.

[0007] The bottom center of the inner pot has a groove, and the heating element is located at least partially in the groove, with the heating element in contact with the bottom wall of the groove.

[0008] The fixed plate has a protrusion at its center, which is at least partially located in the groove and fits against the bottom wall of the groove. The fixed plate has a folded edge around its perimeter, which fits against the bottom perimeter of the inner pot. A groove is formed between the protrusion and the folded edge.

[0009] A notch is provided on one side of the fixing plate, and wiring terminals are provided at both ends of the heating element, with the wiring terminals extending into the notch.

[0010] The disassembly and fixing part includes a first fixing hole on the inner pot and a second fixing hole on the fixing plate. After the fastener passes through the first fixing hole, it is fastened to the second fixing hole so that the fixing plate is fixed to the bottom of the inner pot.

[0011] The bottom of the inner pot is provided with several downward-recessed first recesses in a ring shape, and the fixing plate is provided with several downward-recessed second recesses in a ring shape. The first recesses fit into the second recesses. The first fixing holes are provided on the first recesses, and the second fixing holes are provided on the second recesses.

[0012] The inner pot contains a heating container, and a snap-action switch is located at the bottom of the inner pot. The snap-action switch contacts the bottom of the heating container. A raised edge is located at the center of the bottom of the inner pot, and a clearance hole is located inside the raised edge. The snap-action switch passes through the clearance hole. A through hole is located at the center of the fixing plate, and the raised edge passes through the through hole.

[0013] The heating element is a heating tube.

[0014] The electric slow cooker includes an outer shell, an inner pot inside the outer shell, and a display and control board on the outer shell, which is electrically connected to the heating element.

[0015] This electric slow cooker features a fixed plate that is secured to the bottom of the inner pot via a detachable fixing part. The heating element is press-fitted between the bottom of the inner pot and the fixed plate. If the heating element is damaged, it can be repaired or replaced simply by removing the fixed plate, making maintenance convenient. Moreover, this fixing method is not limited by the material of the inner pot, such as avoiding the welding difficulties that occur when the inner pot is made of aluminum. In addition, the press-fit method ensures that the heating element is in close contact with the bottom of the inner pot over a large area, reducing thermal resistance and allowing heat energy to be transferred more effectively to the heating container inside the inner pot.
