Problems solved by technology

[0004] However, in the above-mentioned anti-dry-burning protection device for the electromagnetic cooker pot, the photosensitive element 5 needs to respond when the pot is dry-burned and turns red, so that when the induction cooker stops power output according to the change of the photosensitive element 5, the pot has already occurred. Dry burning phenomenon, that is, the pan will still be dry-burned during the use of the induction cooker, which will cause certain damage to the pan

Embodiment 1

[0045] figure 2 It is a schematic structural diagram of the induction cooker provided in Embodiment 1 of the present invention; image 3 It is a schematic diagram of the split structure of the induction cooker provided in the first embodiment of the present invention, Figure 4 It is a schematic structural diagram of the inner liquid level in the cooker of the induction cooker provided in the first embodiment of the present invention is lower than the induction device; Figure 5 It is a structural schematic diagram showing that the liquid level in the cooker of the induction cooker is higher than that of the induction device provided in the first embodiment of the present invention, as shown in Fig. Figure 2-5 As shown, in this embodiment, the induction cooker includes: an induction cooker 20 and a pot 10. The induction cooker 20 is provided with a coil disc 22, a control board 24 and a power supply board 21. The coil disc 22 is electrically connected to the control board 2...

Embodiment 2

[0058] Image 6 It is a schematic diagram of the split structure of the induction cooker provided in the second embodiment of the present invention, such as Image 6 As shown, the difference between this embodiment and the above-mentioned embodiment is: in this embodiment, the induction device 30 is arranged on the concave surface of the inner recess 11, that is, the induction device 30 is arranged on the cookware 10 and is located in the inner recess 11 toward the convex portion 23, wherein the induction end of the induction device 30 is in contact with the concave surface of the inner recess 11, so that the induction end of the induction device 30 can sense the liquid level in the cooker 10. Therefore, when the induction device 30 is arranged on the concave portion 11 of the cookware 10, the other end of the induction device 30 can abut against the convex portion 23 when the cookware 10 is placed on the induction cooker 20, which is convenient for the induction device 30 It...

Abstract

The invention provides induction cooker cooking utensil and a dry heating prevention control method thereof. The induction cooker cooking utensil comprises an induction cooker (20) and a cookware (10); a coil plate (22) and a control board (24) are arranged in the induction cooker (20); a boss (23) raised towards the cookware (10) is arranged on a plate heating zone of the induction cooker (20); an indented part (11) matched with the boss is formed in the bottom of the cookware (10); an induction device (30) for inducting the liquid level in the cookware (10) is arranged between the boss (23)and the indented part (11); the induction device (30) is higher than the lowest bottom surface in the cookware (10) in the vertical direction; and the induction device (30) is electrically connected with the control board (24). The induction cooker cooking utensil solves the problem that the cookware is already subjected to dry heating when an existing induction cooker stops heating.

Description

technical field [0001] The invention relates to a household appliance, in particular to an induction cooker and a control method for preventing dry burning. Background technique [0002] Induction cooker has become a widely used cooking utensil. Induction cooker is an electrical cooking utensil made by using the principle of electromagnetic induction heating. When in use, an alternating current is passed into the coil disk, and an alternating magnetic field is generated around the coil. Most of the magnetic lines of the alternating magnetic field pass through the metal pot body, generating a large amount of eddy currents in the bottom of the pot, thereby generating the heat required for cooking. , When the induction cooker heats the pot, it is easy to cause dry burning when there is less or no liquid in the pot, and when the induction cooker is dry, it is easy to cause damage to the pot and the induction cooker. [0003] At present, the patent (CN202074583U) discloses an an...
