Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0049] Refer to the following Figures 1 to 11 The coil disk assembly 100 and the cooking utensil 200 provided according to some embodiments of the present invention are described.

[0050] like Figure 1As shown, according to a first aspect of the present invention, the present invention provides a coil disk assembly 100, the coil disk assembly 100 includes a first coil disk 110 and a second coil disk 120, the first coil disk 110 is located on one side of the second coil disk 120, that is, the coil disk assembly 100 includes two coil layers, wherein the first coil disk 110 includes a first coil 112 and a second coil 114, the first coil 112 and the second coil 114 are arranged side by side, and the second coil disk 120 includes a third coil 122, the third coil 122 is arranged corresponding to the first coil 112 and the second coil 114, and then the magnetic field generated by the third coil 122 when it is energized shields the magnetic field emitted by the first coil 112 and the second coil 114 to the third coil 122.

[0051] Specifically, the first coil 112 is arranged in the first direction of the second coil 114, the second coil 114 is arranged in the second direction of the first coil 112, and the second coil disk 120 is arranged on the first side of the first coil disk 110, that is, the third coil 122 is arranged on the first side of the first coil disk 110, and the winding method of the third coil 122 can be from the first direction of the second coil 114 to the second direction of the first coil 112, extending and winding in a spiral. Figure 1 , Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the first direction of the second coil 114 is the BA direction, and the second direction of the first coil 112 is the AB direction. Figure 1 , Figure 5 and Figure 6 As shown, the first side of the first coil disk 110 is the C side, and the second side of the first coil disk 110 is the D side.

[0052] Furthermore, the north pole of the magnetic field generated when the first coil 112 is energized is toward the first side of the first coil disk 110, and the north pole of the magnetic field generated when the second coil 114 is energized is toward the second side of the first coil disk 110. The first side and the second side of the first coil disk 110 are opposite sides of the first coil disk 110. The south pole (S pole) of the magnetic field generated when the third coil 122 is energized is toward the first direction of the second coil 114, and the north pole (N pole) of the magnetic field generated when the third coil 122 is energized is toward the second direction of the first coil 112.

[0053] The coil disk assembly 100 provided by the present invention includes a first coil disk 110 and a second coil disk 120, and the first coil disk 110 and the second coil disk 120 are stacked together, wherein the first coil disk 110 includes a first coil 112 and a second coil 114, and the first coil 112 and the second coil 114 are arranged side by side, and the second coil disk 120 includes a third coil 122, and the third coil 122 forms a multi-layer structure with the first coil 112 and the second coil 114.

[0054] Furthermore, the first coil 112 is located in a first direction of the second coil 114, and the second coil 114 is located in a second direction of the first coil 112, the first direction and the second direction are opposite directions, and the third coil 122 is located on a first side of the first coil 112 and the second coil 114, and the first coil 112 and the second coil 114 are located on a second side of the third coil 122.

[0055] When the first coil 112, the second coil 114 and the third coil 122 are energized, a magnetic field is generated, wherein the magnetic fields of the first coil 112 and the second coil 114 are opposite, specifically, the north pole of the magnetic field generated by the first coil 112 faces the first side of the first coil disk 110, that is, faces the second coil disk 120, the north pole of the magnetic field generated by the second coil 114 faces the second side of the first coil disk 110, that is, faces away from the second coil disk 120, and the north pole of the magnetic field generated by the third coil 122 faces the second direction of the first coil 112, and the south pole of the magnetic field generated by the third coil 122 faces the first direction of the second coil 114, that is, the south pole of the magnetic field generated by the third coil 122 faces the first direction of the second coil 114. The north pole of the magnetic field generated by the third coil 122 corresponds to the north pole of the magnetic field generated by the first coil 112, and the first coil 112, the second coil 114 and the third coil 122 can form a Halbach array, so that the third coil 122 can guide the magnetic field of the first coil 112 and the second coil 114, thereby shielding the magnetic field on the side of the second coil disk 120 in the coil disk assembly 100, and increasing the magnetic field on the side of the first coil disk 110 in the coil disk assembly 100, thereby improving the heating effect of the coil disk assembly 100, and, due to the cancellation of the magnetic strip, reducing the influence of the coil disk assembly 100 on other electrical equipment.

[0056] Among them, Fig.10 As shown, the Halbach array is a group of magnet arrays 300, which are composed of a radial permanent magnet array and an orthogonal permanent magnet array arranged crosswise, and can achieve the strongest magnetic field with the least magnets. The present invention simulates the Halbach array through the first coil 112, the second coil 114 and the third coil 122. When the coil disk assembly 100 is powered on, the first coil 112, the second coil 114 and the third coil 122 form a Halbach array, thereby reducing the magnetic field strength on one side of the second coil disk 120 on the coil disk assembly 100, thereby achieving a shielding effect.

[0057] Furthermore, since a plurality of coils are disposed on the first coil disk 110 , the heating area of ​​the coil disk assembly 100 is more uniform, and the heating blind area of ​​the coil disk assembly 100 is reduced.

[0058] Specifically, the directions of the south pole and north pole of the magnetic field generated by the first coil 112, the second coil 114 and the third coil 122 are related to the direction of the current passing through the coils. Using Ampere's law, the directions of the south pole and north pole of the magnetic field generated by the coils can be determined by the direction of the current in the coils.

[0059] The present invention mainly lies in the directions of the south pole and the north pole of the magnetic field generated by the first coil 112, the second coil 114 and the third coil 122. The first coil 112, the second coil 114 and the third coil 122 can have a variety of winding methods.

[0061] The third coil 122 is arranged correspondingly to the first coil 112 and the second coil 114 .

[0062] In this embodiment, the first coil disk 110 includes a first disk body 116, and the first coil 112 and the second coil 114 are both arranged on the first disk body 116. The second coil disk 120 also includes a second disk body 124, and the third coil 122 is arranged on the second disk body 124. Moreover, the third coil 122 is arranged relative to the first coil 112 and the second coil 114, and then the first coil 112 and the second coil 114 are arranged on the first disk body 116, and the third coil 122 is arranged on the second disk body 124, which makes it easier to assemble the first coil 112, the second coil 114 and the third coil 122, reduces production difficulty, and improves production efficiency.

[0063] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, as a possible embodiment of the present invention, a first receiving groove 1162 is provided on the side of the first disk body 116 facing away from the second disk body 124, and the first coil 112 is arranged in the first receiving groove 1162. A second receiving groove 1164 is also provided on the side of the first disk body 116 facing away from the second disk body 124, and the second coil 114 is arranged in the second receiving groove 1164, wherein the first receiving groove 1162 and the second receiving groove 1164 are arranged side by side, and thus the first coil 112 and the second coil 114 form a side by side structure.

[0064] In this embodiment, a first accommodating groove 1162 and a second accommodating groove 1164 are provided on a side of the first disk body 116 facing away from the second disk body 124, and the first accommodating groove 1162 and the second accommodating groove 1164 are arranged side by side, so that the first coil 112 is arranged in the first accommodating groove 1162, and the second coil 114 is arranged behind the second accommodating groove 1164, the first coil 112 is located in a first direction of the second coil 114, and the second coil 114 is located in a second direction of the first coil 112, and both the first accommodating groove 1162 and the second accommodating groove 1164 are in a spiral structure, which makes it easier to fix the first coil 112 and the second coil 114, so that the first coil 112 and the second coil 114 can maintain a spiral winding state.

[0065] Specifically, part of the bottom of the first receiving groove 1162 may be hollowed out to facilitate heat dissipation of the first coil 112 . Similarly, part of the bottom of the second receiving groove 1164 may be hollowed out to facilitate heat dissipation of the second coil 114 .

[0066] The first receiving groove 1162 is provided with a first partition plate, and the wire of the first coil 112 is coiled along the first partition plate, thereby improving the stability of the first coil 112, and isolating the wire by the first partition plate to reduce the heat accumulation of the first coil 112. The first partition plate can be spiral, or can be set in a discontinuous form at the first partition plate, so that the wire can change direction at the position where the first partition plate is discontinuous to achieve spiral coiling.

[0067] A second partition plate is disposed in the second receiving groove 1164, and the wire of the second coil 114 is coiled along the second partition plate, thereby improving the stability of the second coil 114, and isolating the wire by the second partition plate to reduce the heat accumulation of the second coil 114. The second partition plate can be spiral, or the second partition plate can be set in a discontinuous form, so that the wire can change direction at the position where the second partition plate is discontinuous to achieve spiral coiling.

[0068] by Figure 6 Taking the first disk body 116 as a reference, the first partition plate in the first receiving groove 1162 is arranged horizontally, and the first coil 112 is horizontally wound in the first receiving groove 1162, which is left-in and right-out or right-in and left-out. Similarly, the second partition plate in the second receiving groove 1164 is arranged horizontally, and the second coil 114 is horizontally wound in the second receiving groove 1164, which is left-in and right-out or right-in and left-out.

[0069] That is, the first coil 112 is a disc-shaped structure, and the second coil 114 is a disc-shaped structure.

[0070] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, as a possible embodiment of the present invention, the first receiving groove 1162 and the second receiving groove 1164 are connected, and then the wire 126 can connect the first coil 112 and the second coil 114 in the connected first receiving groove 1162 and the second receiving groove 1164.

[0071] In this embodiment, the first accommodating groove 1162 and the second accommodating groove 1164 are connected, and the first coil 112 and the second coil 114 are electrically connected by conduction, so that the first coil 112 and the second coil 114 can have only one lead wire, which makes the connection of the first coil 112 and the second coil 114 simpler, and the current on the first coil 112 and the second coil 114 is more stable and more consistent, thereby improving the uniformity of heating of the coil disk assembly 100.

[0072] Specifically, the first accommodating groove 1162 has a first opening on the side facing the second accommodating groove 1164, and the second accommodating groove 1164 has a second opening on the side facing the first accommodating groove 1162, and the first opening and the second opening are connected, that is, the disk body is located in the regional groove between the first opening and the second opening, thereby connecting the first accommodating groove 1162 and the second accommodating groove 1164.

[0073] Furthermore, the wire 126 is arranged in the first open opening and the second open opening, so as to realize the electrical connection between the first coil 112 and the second coil 114 , wherein the communication position of the first accommodating groove 1162 and the second accommodating groove 1164 can be in the middle position of the first disk body 116 .

[0074] like Figure 1 As shown in FIG. 1 , as a possible embodiment of the present invention, the outermost circle of the first coil 112 and the outermost circle of the second coil 114 are connected by a wire 126, and the first coil 112 and the second coil 114 have the same rotation direction, so when the first coil 112 and the second coil 114 are energized, the current directions of the first coil 112 and the second coil 114 are opposite, thereby ensuring that the magnetic fields generated by the first coil 112 and the second coil 114 are opposite in direction. Specifically, as Figure 3 As shown, the current direction of the first coil 112 is I 1 , the current direction of the second coil 114 is I 2 , the current direction I in the adjacent first coil 112 and the second coil 114 1 and I 2 The same, that is, I 1 and I 2 The rotation directions in the first coil 112 and the second coil 114 are opposite, and according to Ampere's law, it can be determined that the directions of the magnetic fields of the two are opposite.
