The present invention provides a cooking appliance, referring to fig. 1 and 2, which may be an electric cooker, an electric pressure cooker, an electric stewpot, etc., and is not limited herein. The cooking utensil comprises a pot body 1, an inner pot 2 arranged in the pot body 1, a temperature controller 3 and an electromagnet 4; the temperature controller 3 is movably arranged on the pot body 1; a gap is arranged between the inner pot 2 and the temperature controller 3. The electromagnet 4 is arranged on one side, far away from the inner pot 2, of the temperature controller 3, and after the electromagnet 4 is electrified, the temperature controller 3 is propped against. The temperature controller 3 moves towards the direction of the inner pot 2 under the pushing of the electromagnet 4 so as to be attached to the inner pot 2, so that the temperature controller 3 can accurately sense the temperature of the inner pot 2.
The temperature controller 3 can be arranged at a plurality of positions of the pot body 1, such as the inner side wall and the bottom; in this scheme, the temperature controller 3 is set at the bottom of the pan body 1; at this time, the temperature controller 3 at the bottom of the pan body 1 extends along the up-down direction, and the upper surface of the temperature controller is a temperature sensing surface; the temperature controller 3 is arranged at the bottom of the pot body 1 and is positioned below the inner pot 2, and the electromagnet 4 is arranged below the temperature controller 3. The temperature sensing surface is lower than the notch of the mounting groove, namely, when the cooking utensil is not in a working state, the temperature sensing surface of the temperature controller 3 is in a concave state relative to the surface of the bottom of the pot body 1. At this time, after the inner pot 2 is placed in the pot body 1, a gap is formed between the bottom of the inner pot 2 and the temperature sensing surface of the temperature controller 3. It should be noted that, the up-down direction in this scheme is made according to the direction under the normal use state of cooking utensil. In the following embodiment, the temperature controller 3 is provided below the inner pan 2.
The structure of the temperature controller 3 is not limited, and the temperature controller 3 has the function of detecting the temperature of the pan bottom; in this scheme, the temperature controller 3 needs to be attached to the bottom of the inner pot 2 to detect the temperature of the bottom of the pot; in one embodiment, a temperature sensor is provided in the temperature controller 3.
Specifically, when the cooking appliance is not working, that is, the temperature of the inner pot 2 does not need to be detected, the electromagnet 4 is in a power-off state and does not have thrust; at this time, the temperature controller 3 is accommodated in the installation groove at the bottom of the pot body 1 under the action of gravity, and a gap is formed between the temperature sensing surface of the temperature controller 3 and the bottom of the inner pot 2; at this time, no matter the user picks up the inner pot 2 or puts the inner pot 2 in, the bottom of the inner pot 2 will not contact and rub with the temperature controller 3.

When the cooking utensil finishes cooking, the electromagnet 4 is powered off, and as the electromagnet 4 does not have a pushing force on the temperature controller 3, the temperature controller 3 and the electromagnet 4 fall under the action of self gravity, so that the temperature sensing surface of the temperature controller 3 is separated from the bottom of the inner pot 2. It will be appreciated that when the temperature controller 3 is arranged at the side of the pan body 1, when the electromagnet 4 is powered off, a user can manually push the temperature controller 3 into the mounting groove after picking up the inner pan 2. Or, the electromagnet 4 is connected with the temperature controller 3, so that when the electromagnet 4 is reset by itself after power-off, the temperature controller 3 can move along with the electromagnet 4 in a direction away from the inner pot 2, so as to realize that the temperature controller 3 is separated from the inner pot 2.

According to the technical scheme, the electromagnet 4 is arranged in the cooking utensil, and the electromagnet 4 is arranged on one side of the temperature controller 3 away from the inner pot 2; when the electromagnet 4 is in a non-energized state, the temperature controller 3 and the inner pot 2 have a gap, so that friction can not be generated with a temperature sensing surface of the temperature controller 3 when the inner pot 2 is put in or taken up, and the sensitivity of the temperature controller 3 can be ensured after long-term use; under the power-on state, the electromagnet 4 generates a propping force on the temperature controller 3, so that the temperature controller 3 moves towards the inner pot 2 to be attached to the bottom of the inner pot 2, and the temperature controller 3 can collect the temperature of the bottom of the inner pot 2, so that the cooking utensil can work normally. According to the technical scheme, the position of the temperature controller 3 relative to the inner pot 2 is controlled by controlling the electrifying state of the electromagnet 4, so that the temperature controller 3 is effectively protected from being worn by the inner pot 2 on the premise of ensuring the normal operation of the temperature controller 3, and the service lives of the temperature controller 3 and the cooking utensil are prolonged.

When the electromagnet 4 is not electrified, the push rod 42 can extend into the pushing channel 34 and even be attached to the abutting part 33, so that when the electromagnet 4 is electrified, the push rod 42 can immediately abut against the temperature controller 3. Further, the abutment 33 extends in the radial direction of the pushing channel 34 to form an abutment plate; the surface of the abutment plate facing the push rod 42 is planar.

Further, a heat-resistant material is disposed between the electromagnet 4 and the temperature sensing device 32. The heat-resistant material can be foamed plastic or diatomite, silica, glass fiber, asbestos and other materials. In this embodiment, the heat-resistant material may be disposed in the temperature controller bracket 31.
In order to control the movement travel of the temperature controller 3 in the mounting groove, when the pushing force is large, the push rod 42 is prevented from driving the temperature controller 3 to collide with the inner pot 2, so that the inner pot 2 is damaged and uncomfortable for a user, therefore, the temperature controller 3 further comprises a limit groove 35, the limit groove 35 is arranged on the outer surface of the temperature controller bracket 31, and the limit groove 35 extends along the length direction of the temperature controller bracket 31; the pot body 1 is provided with a mounting groove for accommodating the temperature controller 3, the groove wall of the mounting groove is convexly provided with at least one limiting piece, and the limiting piece extends into the limiting groove 35 and respectively abuts against the groove walls at two sides of the limiting groove 35 so as to limit the movement stroke of the temperature controller 3 in the mounting groove.
