Description

Technical Field

[0002] At present, the coupler structure of electric hot pots and electric baking pans is mostly that a single coupler controls a heating tube. If two or more heating tubes need to be controlled, a corresponding number of couplers must be used simultaneously. This makes the coupler structure of the product more complicated, and the coupler occupies a large space in the product, which will cause the size of the whole product to be larger and the cost to be higher.

As a result, the downward movement resistance of the guide rib of the upper heating plate is large, which makes the process of pressing the heating plate down into place not smooth enough.

[0004] Therefore, further improvements are necessary. Utility Model Content
