Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items. The term "plurality" as used herein refers to two or more.

Referring to fig. 1, the present invention provides a cooking appliance, which includes a power base 1 and a pot 2. The power base 1 is provided with a first positioning portion 11, the pot 2 is provided with a second positioning portion 21, and the second positioning portion 21 is matched with the first positioning portion 11. The pot 2 is fitted to the power base 1 at a certain position by the second positioning part 21 cooperating with the first positioning part 11. It should be noted that the "determined position" means that the pot 2 can only be assembled on the power base 1 in a unique manner, and after the pot 2 is rotated by a certain angle (not an integral multiple of 360 °), the pot 2 cannot be assembled on the power base 1. This cooking utensil can confirm the assembly position of pan 2 through the cooperation of second location portion 21 with first location portion 11, has avoided the problem of pan 2 discernment mistake because of pan 2 assembly position mistake appears.

Referring to fig. 6 and 12, the power base 1 is provided with a plurality of control switches 3, each control switch 3 can be triggered to start a corresponding cooking function, the pot 2 is provided with a switch trigger 4, and when the pot 2 is assembled on the power base 1, the switch trigger 4 triggers at least one control switch 3 to start the cooking function corresponding to the triggered control switch 3. In order to meet various cooking requirements, the cooking appliance includes a plurality of pans 2, and specifically, the pans 2 may be a rice cooker (as shown in fig. 2), a frying pan (as shown in fig. 1), a saucepan (as shown in fig. 3) or a cooking pan (as shown in fig. 4), and may also be other types of pans, so as to meet various cooking requirements such as frying, cooking, stewing, steaming, and the like. Different types of cookware 2 can be provided with the switch trigger 4 at different positions, so as to trigger different control switches 3, identify different types of cookware 2 and correspondingly start different cooking functions. For example, when the rice cooker is assembled on the power base 1, the rice steaming function is started; when the frying pan is assembled on the power supply base, the frying function is started; when the saucepan is assembled on the power base 1, the function of boiling is started.

This cooking utensil can confirm the assembled position of pan 2 through the cooperation between second location portion 21 and the first location portion 11 to guaranteed that switch trigger 4 can pinpoint and trigger corresponding control switch 3, guaranteed that power base 1 can correctly discern pan 2 and start corresponding culinary art function. This cooking utensil has possessed the function of accurate positioning pan 2 and 2 types of discernment pan simultaneously, simple structure, easily assembly, and the cost is lower.
