Embodiment 1

[0028] Such as Figure 1~3 As shown, it is an electromagnetic cooking utensil that can three-dimensionally heat a cooking container according to the present invention, including an induction cooker 10, which has a built-in excitation coil 11 that generates an alternating magnetic field. Device 20, coupling heating device 20 comprises coupling coil 22 and the electromagnetic heating coil 21 that is connected with coupling coil 22, and in the present embodiment electromagnetic heating coil 21 is the side heating coil that heats the side wall of cooking container, and coupling coil 22 can be connected with excitation coil 11 Electromagnetic coupling. The coupling coil 22 and the electromagnetic heating coil 21 are connected in series to form a closed loop. When the electromagnetic oven 10 is working, an alternating induction magnetic field is generated in the exciting coil 11, and the alternating current generated by the coupling coil 22 in the alternating magnetic field is drive...

Embodiment 2

[0038] Such as Figure 6 Shown is another embodiment of the present invention, and its difference from Embodiment 1 is: a magnetically conductive support 23 is installed between the coupling coil 22 and the electromagnetic heating coil 21, the magnetically conductive support 23 is H-shaped, the coupling coil 22 and the electromagnetic heating coil 21 The heating coils 21 are connected in a closed loop, and the two are coupled through a magnetic field. The coupling coil 22 and the electromagnetic heating coil 21 are both arranged in the groove of the magnetically permeable bracket 23 . When the induction cooker 10 is started to work, the coupling coil 22 is in the alternating magnetic field, and the alternating magnetic field forms an alternating current in the coupling coil 22, and the alternating current generates an alternating magnetic field, and the magnetic field lines envelop the electromagnetic heating coil through the magnetically conductive support 23 21. Make an alte...

Embodiment 3

[0041] Such as Figure 7 Shown is another embodiment of the coupling heating device of the present invention, and the electromagnetic heating coil 21 is arranged in a cylindrical shape. The base body 24 and the bottom cover 27 form a cylindrical casing, and the coupling coil 22 and the electromagnetic heating coil 21 are arranged in the casing. When in use, the cylindrical cooking utensil is placed in the cylindrical casing to realize three-dimensional heating.

[0042] The electromagnetic cooking device in this creation can be applied to other heating devices with electromagnetic heating function, and also achieve a three-dimensional heating effect.

Abstract

The invention discloses an electromagnetic cooking appliance capable of three-dimensionally heating a cooking container. The electromagnetic cooking appliance comprises an electromagnetic oven and a coupling heating device, wherein an excitation coil capable of generating alternating magnetic field is arranged in the electromagnetic oven; the coupling heating device can be combined with the electromagnetic oven for use and is arranged on the electromagnetic oven; the coupling heating device comprises a seat, an electromagnetic heating coil and a coupling coil for providing energy for the electromagnetic heating coil; and the coupling coil is electromagnetically coupled and correspondingly arranged with the excitation coil. The electromagnetic cooking appliance disclosed by the invention transmits energy from the electromagnetic oven to the electromagnetic coupling heating device in an electromagnetic coupling mode to three-dimensionally heat the cooking container, thereby improving cooking effect of the electromagnetic oven, promoting market capacity of the electromagnetic oven, simultaneously, overcoming the defects that the electromagnetic oven is apt to stick bottom and explode by concentrated heating, and improving use security.

Description

technical field [0001] The invention relates to the field of kitchen appliances, in particular to an electromagnetic cooking appliance capable of three-dimensionally heating a cooking vessel. Background technique [0002] Electromagnetic cooking utensils in the prior art, such as an induction cooker, generate a high-frequency alternating magnetic field during cooking to heat the bottom of the pot. This heating method has a high thermal efficiency, which can be as high as 92%, which is 2 percentage points higher than the first-level energy efficiency standard stipulated by the state. It is currently the most efficient kitchen cooking appliance. Divided according to the shape and characteristics of the support panel, induction cookers generally include two types: flat stoves and concave stoves. Flat stoves are suitable for heating pans, and concave stoves are suitable for heating round-bottomed pans. When the flat stove is heated, only the bottom of the pot is heated, and the...
