Description

TECHNICAL FIELD

[0001] The present application relates to an energy-saving plate, in particular, an energy-saving plate specially used for an electromagnetic oven and having a heightening function. BACKGROUND

[0002] It is known that the electromagnetic oven adopts the electromagnetic induction heating principle, and uses the magnetic field generated by the current through the coil. When the iron-containing pot is placed on the oven surface, the magnetic force in the magnetic field will generate countless small eddy currents through the bottom of the pot, so that the pot is heated at a high speed, thereby heating the food in the pot.

[0003] Generally speaking, iron, stainless steel No. 430 and stainless steel No. 304 with magnetic can be placed on the electromagnetic oven for cooking, because the resistance is large; pots made of non-magnetic materials such as aluminum, copper, alloy, ceramic, glass and stainless steel No. 304 and 316 cannot be used on the electromagnetic oven, because the resistance is small and cannot generate electromagnetic effect.

[0004] Therefore, when pots made of aluminum, copper, alloy, ceramic, glass and stainless steel No. 304 and 316 are used on the electromagnetic oven, it is necessary to attach a magnetic conductive metal piece to the outside or inside of the bottom of the pot, which can induce the magnetic field generated by the electromagnetic oven. The magnetic force in the magnetic field will generate countless small eddy currents through the metal piece at the bottom of the pot, so that the pot is heated at a high speed, thereby heating the food in the pot.

[0005] Although the pots made of aluminum, copper, alloy, ceramic, glass and stainless steel No. 304 and 316 are used as a conductive medium between the pot and the electromagnetic oven through the magnetic conductive metal piece, the temperature between the magnetic conductive metal piece and the oven surface cannot be dissipated because the magnetic conductive metal piece is too close to the oven surface, which leads to a high temperature between the magnetic conductive metal piece and the oven surface. When the temperature is too high, the power supply of the electromagnetic oven will be cut off, so that the electromagnetic oven cannot be used for a short time, causing the user's trouble in use.

[0006] Therefore, how to prevent the temperature between the magnetic conductive metal piece and the oven surface from being too high so that the electromagnetic oven does not automatically cut off the power is the problem to be solved by the present application. CONTENT OF THE INVENTION

[0048] The technical content and detailed description of the present application are described as follows in conjunction with the accompanying drawings:

[0049] Please refer to Figure 1 , 2 , the exploded view of the back of the energy-saving plate of the present application and Figure 1 the back view of the assembled energy-saving plate. As shown in the drawings: the energy-saving plate with the function of raising the height of the electromagnetic stove of the present application, the energy-saving plate 10 comprises: a heat-conducting disc 1 and an induction disc 2. Among them, the induction disc 2 is installed at the bottom of the heat-conducting disc 1, so that the heat-conducting disc 1 can be used on the electromagnetic stove (not shown in the figure), and at the same time, the induction disc 2 and the stove surface (not shown in the figure) of the electromagnetic stove have a heat dissipation space (not shown in the figure), which avoids the induction disc 2 and the stove surface of the electromagnetic stove from overheating, causing the electromagnetic stove to automatically power off.

[0050] The heat-conducting disc 1 has a heated surface 11 on one side, a surrounding wall 12 around the heated surface 11, a recessed part 13 formed by the surrounding wall 12, at least one heat-conducting convex part 14 in the recessed part 13, the heat-conducting convex part 14 comprising a first heat-conducting convex part 141, a second heat-conducting convex part 142 and a third heat-conducting convex part 143. The first heat-conducting convex part 141 is arranged at the central position of the recessed part 13 and has a circular shape. The second heat-conducting convex part 142 is arranged around the first heat-conducting convex part 141 in a radial manner. There are third heat-conducting convex parts 143 of different shapes or different sizes between each of the first heat-conducting convex part 141 and the second heat-conducting convex part 142. The second heat-conducting convex part 142 is in the shape of a long strip; the third heat-conducting convex part 143 is in the shape of a circular column, a triangular column or a square column. In addition, a plurality of protrusions 121 are protruding around the surrounding wall 12, and the plurality of protrusions 121 are used to raise the energy-saving plate 10, so that the induction disc 2 and the stove surface (not shown in the figure) of the electromagnetic stove (not shown in the figure) form a heat dissipation space (not shown in the figure). In the present drawing, the heat-conducting disc 1 is made of aluminum or aluminum alloy.

[0051] 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).

[0052] When the induction disk 2 is installed in the recess 13 of the heat-conducting disk 1, the surrounding wall 12 can be processed by a machining tool to bend and cover the circumference of the induction disk 2, so that the induction disk 2 can be firmly combined with the heat-conducting disk 1, and the plurality of protrusions 121 are located below the induction disk 2.

[0053] Please see Figure 3 , 4 ,for Figure 2 Front view of the energy-saving panel assembly and Figure 2 A 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.

[0054] When the energy-saving plate 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.

[0055] When the energy-saving plate 10 is placed on the induction cooker (not shown in the figure), the multiple protrusions 121 raise the energy-saving plate 10, so that a heat dissipation space is formed between the induction plate 2 and the surface of the induction cooker (not shown in the figure), so as to avoid the temperature between the energy-saving plate 10 and the surface of the induction cooker being too high, which would cause the induction cooker to automatically shut off.

[0056] Please see Figure 5As shown in the figure: when the energy-saving plate 10 of the present application is in use, the heat-conducting disc 1 is placed on the stove surface 201 of the electromagnetic stove 20, the plurality of protrusions 121 raise the energy-saving plate 10, so that the induction disc 2 and the stove surface 201 of the electromagnetic stove 20 have a heat dissipation space 40, and the induction disc 2 corresponds to the coil disc (not shown in the figure) inside the electromagnetic stove 20. Then the pot 30 is placed on the heat-conducting surface 15 of the heat-conducting disc 1.

[0057] When the electromagnetic stove 20 is started, a magnetic field is generated by the current passing through the coil, and the magnetic force in the magnetic field generates countless small eddy currents through the induction disc 2, so that the induction disc 2 generates high-speed heating. After the induction disc 2 generates heat energy, the heat energy is rapidly 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 protrusion 14 of the heat-conducting disc 1, which in turn transfers the heat energy to the heat-conducting surface 15, and then the heat-conducting surface 15 conducts the heat energy to the heat-conducting pad 16 and the plurality of heat-conducting protrusions 17, so that the heat-conducting disc 1 can heat the food in the pot 30.

[0058] During the heating or cooking process, the plurality of protrusions 121 raise the energy-saving plate 10, so that the induction disc 2 and the stove surface 201 of the electromagnetic stove 20 have a heat dissipation space 40, so that the heat source does not gather between the induction disc 2 and the stove surface 201 of the electromagnetic stove 20, causing the electromagnetic stove to automatically power off. In the figure, the height of the heat dissipation space 40 is between 1mm and 5mm.

[0059] In addition, during the heating or cooking process, if the boiling soup spills out of the pot 30, the soup can directly flow into the groove 18 and dry burn and evaporate, thereby avoiding the soup from flowing to the outside or inside of the electromagnetic stove 20 and dirtying or damaging the electromagnetic stove 20, or affecting the normal operation of the electromagnetic stove 20.

[0060] The above-mentioned is only the preferred embodiment of the present application, which is not intended to limit the scope of patent protection of the present application. Therefore, any equivalent changes made by using the contents of the specification or the drawings are also included in the scope of protection of the present application, and it is hereby declared.
