Abstract
Description
Technical Field
[0001] This application relates to an energy-saving panel, and more particularly to an energy-saving panel structure for use in an induction cooker. Background Technology
[0002] It is known that induction cookers use the principle of electromagnetic induction heating. They utilize the magnetic field generated by the current passing through a coil. When an iron-containing pot is placed on the cooktop, the magnetic force within the magnetic field will generate countless small eddy currents through the bottom of the pot, causing the pot to heat up rapidly, thereby heating the food inside.
[0003] Generally speaking, iron and stainless steel (430) and magnetic stainless steel (304) can be used on induction cookers because of their high resistance. However, non-magnetic cookware such as aluminum, copper, alloys, ceramics, glass, and stainless steel (304, 316) cannot be used on induction cookers because their low resistance prevents them from generating an electromagnetic effect.
[0004] Therefore, when cookware made of materials such as aluminum, copper, alloys, ceramics, glass, and stainless steel (304, 316, etc.) is to be used on an induction cooker, it is necessary to attach a magnetic metal part to the outside or inside of the bottom of these cookware. This magnetic metal part senses the magnetic field generated by the induction cooker. The magnetic force in the magnetic field will generate countless small eddy currents through the metal part at the bottom of the cookware, causing the cookware to heat up rapidly, thereby heating the food inside the pot.
[0005] However, some cookware with magnetic metal parts cannot be used on gas stoves because the gas stove flame will burn the magnetic metal parts, or the magnetic metal parts will detach from the cookware due to material aging after a period of use, making the cookware unsuitable for induction cookers.
[0006] Therefore, how to make these non-magnetic cookwares usable on induction cookers is the problem that this application aims to solve. Utility Model Content

[0045] The technical content and detailed description of this application are now explained in conjunction with the accompanying drawings:
[0046] Please see Figure 1 , 2 This is an exploded view of the back of the energy-saving panel structure of this application. Figure 1A schematic diagram of the back of the assembled energy-saving plate structure. As shown in the figure: the energy-saving plate structure for an induction cooker according to this application, the energy-saving plate structure 10 includes: a heat-conducting plate 1 and an induction plate 2. The induction plate 2 is installed at the bottom of the heat-conducting plate 1, so that the heat-conducting plate 1 can be used on an induction cooker (not shown in the figure).
[0047] The heat-conducting plate 1 has a heated surface 11 on one side, and a surrounding wall 12 surrounds the heated surface 11. The surrounding wall 12 encloses a recess 13, and at least one heat-conducting protrusion 14 is provided in the recess 13. The heat-conducting protrusion 14 includes a first heat-conducting protrusion 141, a second heat-conducting protrusion 142, and a third heat-conducting protrusion 143. The first heat-conducting protrusion 141 is located at the center of the recess 13 and is circular in shape. The second heat-conducting protrusion 142 is radially arranged around the first heat-conducting protrusion 141. Between each of the first heat-conducting protrusion 141 and the second heat-conducting protrusion 142, there are third heat-conducting protrusions 143 of different shapes or sizes. The aforementioned second heat-conducting protrusion 142 is elongated; the third heat-conducting protrusion 143 is a circular column, a triangular column, or a square column. In this figure, the heat-conducting plate 1 is made of aluminum or aluminum alloy.
[0048] The induction plate 2 is installed in the recessed portion 13. The induction plate 2 has a plate body 21, and the plate body 21 is provided with positioning holes 22. The positioning holes 22 include a first positioning hole 221, a second positioning hole 222, and a third positioning hole 223 respectively corresponding to the engagement of the first heat-conducting protrusion 141, the second heat-conducting protrusion 142, and the third heat-conducting protrusion 143. In this figure, the induction plate 2 is made of stainless steel material number 430, magnetic stainless steel material number 304, or iron material. In an induction cooker (not shown), an electric current passes through a coil to generate a magnetic field. The magnetic force in the magnetic field generates numerous small eddy currents on the induction plate 2, causing the induction plate 2 to heat up rapidly and conduct the heat to the heat-conducting plate 1, so that the heat-conducting plate 1 can heat the food in the pot (not shown).
[0049] When the induction plate 2 is installed in the recessed part 13 of the heat conduction plate 1, the enclosure 12 can be processed by a processing tool so that the enclosure 12 is bent and covers the circumference of the induction plate 2, so that the induction plate 2 can be firmly combined with the heat conduction plate 1.
[0050] Please see Figure 3 , 4 ,for Figure 2 Front view of the energy-saving panel structure after assembly and Figure 2A side sectional view is shown in the figure. As shown, a heat-conducting pad 16 is provided at the center of the heat conduction surface 15 of the heat-conducting plate 1 in this application. A plurality of heat-conducting protrusions 17 are provided around the periphery of the heat-conducting pad 16, and a groove 18 is formed between each of the heat-conducting protrusions 17.
[0051] When the energy-saving panel structure 10 is in use, the design of the groove 18 is mainly to ensure that when the pot (not shown in the figure) is heated, the soup that boils and overflows from the pot will directly flow into the groove 18 to dry-boil and evaporate, thereby preventing the soup from flowing out of the induction cooker (not shown in the figure) and getting dirty or damaged, or affecting the normal operation of the induction cooker.
[0052] Please see Figure 5 The figure shows a schematic diagram of an embodiment of this application. As shown, when the energy-saving plate structure 10 of this application is in use, the heat-conducting plate 1 is placed on the induction cooker 20, so that the induction plate 2 corresponds to the induction cooker 20. Then, the cookware 30 is placed on the heat conduction surface 15 of the heat-conducting plate 1.
[0053] When the induction cooker 20 is started, the current passing through the coil generates a magnetic field. The magnetic force in the magnetic field generates countless small eddy currents through the induction plate 2, causing the induction plate 2 to generate high-speed heat. After the induction plate 2 generates heat energy, the heat energy is quickly conducted to the first heat-conducting protrusion 141, the second heat-conducting protrusion 142, and the third heat-conducting protrusion 143 of the heat-conducting plate 1. After being heated, the heat energy is transferred to the heat conduction surface 15, and then from the heat conduction surface 15 to the heat-conducting pad 16 and the heat-conducting protrusion rings 17, so that the heat-conducting plate 1 can heat the food in the pot 30.
[0054] During heating or cooking, if boiling soup overflows the pot 30, the soup can flow directly into the groove 18 to evaporate, thus preventing the soup from flowing to the outside or inside of the induction cooker 20 and getting dirty or damaged, or affecting the normal operation of the induction cooker 20.
[0055] However, the above description is only a preferred embodiment of this application and is not intended to limit the scope of patent protection of this application. Therefore, all equivalent changes made based on the content of this application's specification or drawings are similarly included within the scope of protection of this application and are hereby stated.
