As shown in fig. 1 and 2, an embodiment of the present invention provides a cooking apparatus 100, including a temperature controller, a base 10, a heating plate 20, and a heating plate 30; the temperature controller further includes a temperature measuring element 50, a fixing component 40 and an elastic body 60, wherein the heating plate 20 covers the base 10 and encloses with the base 10 to form a cavity 11, the heating plate 30, the temperature measuring element 50, the fixing component 40 and the elastic body 60 are all disposed inside the cavity 11, and the heating plate 30 can be an electromagnetic heating element, such as a coil plate, or an electric heating element, such as an electric heating wire or an electric heating film.

The heating plate 20 is provided with a temperature measuring hole 21, the temperature measuring element 50 is arranged on the top end of the fixing component 40 in a penetrating manner, the top end of the fixing component 40 extends out of the temperature measuring hole 21, and the fixing component 40 is connected with the temperature measuring hole 21 in a sealing manner; one end of the elastic body 60 is connected to the heating plate 30 or the inner bottom surface of the housing 10, and the other end of the elastic body 60 abuts against the fixing member 40, so that the fixing member 40 is connected to the back surface of the heating plate 20 in a sealing manner.

When the temperature measuring element 50 is arranged on the heating plate 20, in order to realize accurate temperature measurement of the temperature measuring element 50 and ensure that the temperature measuring element 50 can move downwards when a pot is placed on the heating plate 20 and move upwards after the pot is moved away from the heating plate 20. In the prior art, the elastic body 60 is usually arranged at the bottom end of the temperature measuring element 50, and the top end of the temperature measuring element 50 extends out of the heating plate 20, so that when a pot is placed on the heating plate 20, the temperature measuring element 50 moves downwards, the elastic body 60 is compressed, after the pot is removed from the heating plate 20, the temperature measuring element 50 moves upwards under the elastic force of the elastic body 60, and the elastic body 60 can ensure that the temperature measuring element 50 is in close contact with the pot, so as to ensure the accuracy of temperature measurement; or the fixing device with the telescopic function is arranged to fix the temperature measuring element 50 on the fixing device, and the fixing device is used for driving the temperature measuring element 50 to stretch up and down, so that the temperature measuring element 50 can be tightly attached to a pot, and the temperature measuring accuracy of the temperature measuring element 50 is further ensured. However, the elastic body 60 is arranged to accommodate the vertical expansion and contraction condition, so that the temperature measurement is inaccurate, and the arrangement of the fixing device can cause an assembly gap between the fixing device and the heating plate 20, so that the liquid on the heating plate 20 enters the cooking device 100, and dangers such as burning are caused.

To solve the above problems, in the present embodiment, as shown in fig. 1 and 2, the temperature measuring element 50 is mounted in the temperature measuring hole 21 of the heating plate 20 through the fixing member 40, and the fixing member 40 is supported by the elastic body 60 to ensure the sealing property of the connection between the fixing member 40 and the heating plate 20, thereby preventing liquid from entering the cooking apparatus 100 from the gap between the fixing member 40 and the heating plate 20; in addition, the fixing component 40 drives the temperature measuring element 50 to move up and down in a telescopic manner, so that the temperature measuring accuracy of the temperature measuring element 50 can be ensured, and the problem of clamping stagnation can be avoided.

When the elastic body 60 is installed, one end of the elastic body 60 is pushed along the direction of the inclined surface of the outer side wall of the plate-shaped structure approaching the heating plate 20, so that the elastic body 60 is sleeved on the upper end of the boss 4241 and fixed with the guide sleeve 42. Specifically, the plate-shaped structure may be integrally formed with the guide sleeve 42, so that the plate-shaped structure may also serve as a reinforcing rib of the guide sleeve 42, which may increase the strength of the guide sleeve 42 and facilitate fixing the elastic body 60 on the frame 41.
