Description

Technical Field

[0001] This utility model relates to the field of rice cooker technology, specifically a heating element for a rice cooker. Background Technology

[0002] An electric rice cooker is a modern cooking appliance capable of steaming, boiling, stewing, simmering, and braising. The heating element is one of its core components, responsible for converting electrical energy into heat energy to heat the food in the inner pot. It not only cooks the food but also keeps it warm. It is clean, hygienic, and pollution-free, saving time and effort, making it an indispensable tool for modern household chores. As a kitchen appliance that uses electric heat to cook food, the operating temperature of an electric rice cooker is mostly around 100℃. The performance of the heating element directly affects the cooking effect and safety. Proper operation and regular maintenance during daily use can extend its lifespan.

[0003] Currently, when using ceramic inner pots for heating, rice cooker heating plates employ two types of ceramic inner pots: one with a ground bottom and the other without. The ground-bottom ceramic inner pot fits the heating plate better. However, after a period of use, a large amount of dirt accumulates on the surface of the heating plate inside the rice cooker, affecting its heating performance. Existing heating plates require disassembling the bottom of the rice cooker for separation, and aligning them with the bolt holes on the bottom of the rice cooker is difficult when replacing them, making replacement cumbersome. Therefore, we offer a rice cooker heating element to solve these problems. Utility Model Content

[0010] Furthermore, the mounting hole is connected to an external sensor, the heating element is arranged in a ring, and both ends of the heating element are connected to the contact block by extension blocks. The contact block is connected to the extension block by bolts, and both the contact block and the extension block are made of metal.

[0011] Furthermore, the connecting ring has bolt holes for connecting to external sensors, the wire box is Y-shaped, the wire box has wire grooves inside, and the side wall of the wire box is connected to the support column by bolts.

[0012] Furthermore, a stop block is provided on the top side wall of the support column, and the side wall of the wire box engages with the stop block by means of a plug.

[0013] (iii) Beneficial effects:

[0014] Compared with existing technologies, the heating element of this rice cooker has the following advantages:

[0015] I. This utility model uses anti-slip protrusions to move the heating plate into the heat insulation bearing ring. The heating plate presses down on the support frame until it contacts the bottom wall of the heat insulation bearing ring. The rotating heating plate drives the contact frame to engage with the limiting block, thus completing the installation of the heating component. This solves the problem that the heating plate of existing rice cookers needs to be removed from the bottom of the rice cooker to be separated, and has the advantage of easy disassembly.

[0016] II. This utility model solves the problem of difficulty in aligning the bolt holes at the bottom of the rice cooker when replacing the heating plate, which is caused by the existing rice cooker. It has the advantage of convenient installation. The heat insulation bearing ring is fixed to the bottom of the rice cooker with bolts, and the external sensor is fixed in the mounting hole with a connecting ring. The external wires are connected to the contact block and the external sensor respectively. The external wires are stored in the wire box. Attached Figure Description
