Problems solved by technology

Its disadvantages are: because there is a layer of ceramic plate between the electromagnetic cooker and the thermistor, the ceramic plate is not a good conductor of heat, so it is difficult to ensure the accuracy and timeliness of temperature transmission in this method, especially not in a certain temperature range. A specific temperature point sends out accurate and obvious signals in time, so the existing electromagnetic cooker is simply a utensil for heating. It is difficult to realize the automatic temperature control of the cooking process when it is used in conjunction with the electromagnetic cooker. It is necessary to manually switch the program. It is very inconvenient to control the temperature, especially for cooking that does not require too much cooking skills and takes a long time, and requires manual change of program.
Thus limiting the use and development of electromagnetic cooker

Embodiment 1

[0029] figure 1 , figure 2 and image 3 The shown electromagnetic cooking pot that can realize the automatic temperature control of the electromagnetic range is the first embodiment of the present invention, and it is made up of pot body 2, pot cover 7 and temperature controller 3, wherein, the bottom of pot body 2 and the bottom of outer layer pot 1 forms a double-layer structure, the outer pot bottom 1 is made of non-metallic material, the temperature controller 3 is fixed between the bottom interlayers of the pot body 2 and is located in the middle of the pot bottom, and the temperature controller housing 11 is coaxial with the pot body 2 The cylindrical body is integrated with the outer bottom 1 of the pot body, and there is a space in the housing 11 to allow the axial displacement of the permanent magnet. The temperature controller 3 is composed of a housing 11, a temperature sensing element 33 and a permanent magnet 32. The housing 11 is a cylindrical body with upper ...

Embodiment 2

[0033] Figure 4 ~ Figure 7 The shown electromagnetic cooker that can realize the automatic temperature control of the electromagnetic range is the second embodiment of the present invention. The difference from the first embodiment is that the pot body of the electromagnetic cooker is a double-layer structure, consisting of an outer pot body 1, a pot body 2, Pressing ring 6 and sealing ring 5 constitute, and outer pot body 1 can be made of non-metallic material, is pressed by pressing ring 6 at the top junction between outer pot body 1 and pot body 2, and is sealed by sealing ring 5. A gap 4 is formed between the pot body 2 and the outer pot body 1, and the gap 4 can be evacuated or filled with heat-insulating materials to strengthen the heat preservation effect;

[0034]Another difference from the first embodiment is the temperature controller 3. Since the temperature sensing element 33 of the temperature controller is a bimetal 333, the structure of the temperature controll...

Embodiment 3

[0038] Figure 8 ~ Figure 9 The shown electromagnetic cooker capable of automatic temperature control of the electromagnetic range is the third embodiment of the present invention. The temperature controller 3 is composed of a temperature controller housing 11 integrated with the bottom of the outer pot body 1, a temperature sensing element 33, a disk-shaped permanent magnet 32 ​​with annular steps on the edge, and a reset mechanism 31. It is different from the second embodiment. The temperature sensing element 33 in the temperature controller 3 adopts a disc-shaped temperature sensing element 334, and the reset mechanism includes a compression spring 331, a push rod 335 fixed on the permanent magnet 32, and a fixed piece for limiting the trajectory of the push rod 335 moving up and down. 336.

[0039] The specific structure is as follows:

[0040] The center of the fixed piece 336 in the reset mechanism has a through hole, and is horizontally arranged on the middle height o...

Abstract

The electromagnetic pot capable of realizing automatic temperature control of electromagnetic range includes one pot body with one temperature controller comprising casing, temperature sensing element, permanent magnet and repositioning mechanism fixed to the outside. Of the temperature controller, the casing is one tube fixed to the bottom of the pot body and has space for the permanent magnet to shift axially, the temperature sensing element is adhered to bottom of the pot body to sense the temperature of the pot body directly, the permanent magnet below the temperature sensing element can move downwards when the temperature sensing element is heated, and repositioning mechanism repositions the permanent magnet with the temperature change. The temperature controller can send magnetic signal reflecting the temperature change to the electromagnetic range to realize automatic temperature control.

Description

technical field [0001] The invention relates to a cooking pot suitable for an electromagnetic cooker, in particular to an electromagnetic cooker which enables the electromagnetic cooker to realize automatic temperature control in the cooking process. Background technique [0002] The induction cooker is a household cooker that uses the principle of electromagnetic induction to realize the heating function. After the electromagnetic cooker is energized, an alternating magnetic field is generated through its induction coil, and acts on the metal pot bottom on the cooker to generate eddy currents at the bottom of the pot, and the eddy current passes through the pot material. The resistance of the food is converted into heat energy, thereby completing the heating and cooking of food. It can be seen that the induction cooker needs to be used in conjunction with the pot to achieve heating. Only the pot made of ferromagnetic materials can use the thermal effect generated by its own...
