Description

Technical Field

[0001] The invention relates to the field of heaters, in particular to an eccentric eddy current heater. Background Art

[0002] Electric heaters are appliances that use electricity to heat. They are compact, yet offer high heating power and are widely used. They utilize intelligent control modes, resulting in precise temperature control, long lifespan, and high reliability. The core principle behind heaters is energy conversion, the most common of which is the conversion of electrical energy into thermal energy.

[0003] Traditional heaters utilize a single heating method: electrical conduction heats the heating plate, which then transfers heat to the contents. Existing products lack eddy current design, relying solely on the transfer of heat energy from the food or liquid within the container. This results in a slow heating process and can cause thermal damage, potentially damaging the food's structure.

[0004] The purpose of this invention is to design an eccentric eddy current heater to solve the above problems in the prior art. Summary of the Invention

[0005] In view of the problems existing in the above-mentioned prior art, the present invention provides an eccentric eddy current heater, which can effectively solve the problems existing in the above-mentioned prior art.

[0006] The technical solution of the present invention is:

[0007] An eccentric eddy current heater comprises a shell and a cover body matched with the shell, the shell is provided with a handle, a holding cup body is provided inside the shell, and further comprises:

[0008] A graphene heating sheet for heating the food in the holding cup, wherein the graphene heating sheet is disposed between the bottom of the housing and the holding cup, and the geometric center of the graphene heating sheet does not coincide with the geometric center of the holding cup;

[0009] A graphene heat recovery sheet is provided above the holding cup body, and is used to absorb heat energy generated when the food in the holding cup body is heated and radiate far infrared rays downward to heat the food in the holding cup body;

[0010] The area of ​​the graphene heating plate is smaller than the area of ​​the graphene heat recovery plate.

[0011] Furthermore, it further includes a control system and a temperature sensor, wherein the control system is used to obtain temperature information of the temperature sensor and control the start or stop of the graphene heating plate.

[0012] Furthermore, the graphene heating sheet and the graphene heat recovery sheet are circular sheet structures.

[0013] Furthermore, the radius of the graphene heating plate is less than half the radius of the containing cup body.

[0014] Furthermore, a horizontal distance between the centers of the graphene heating plate and the graphene heat recovery plate is smaller than a radius of the graphene heating plate.

[0015] Furthermore, a wireless charging receiving plate is provided at the bottom of the cup body.

[0016] Furthermore, a graphene heat recovery sheet is arranged on the bottom of the cover.

[0017] Furthermore, the geometric center of the graphene heat recovery plate coincides with the geometric center of the containing cup.

[0018] Therefore, the present invention provides the following effects and / or advantages:

[0019] The present invention uses a graphene heating sheet to directly heat the bottom of the cup body. At the same time, during the heating process, the food in the cup body absorbs and transfers heat upward. After absorbing the heat, the graphene heat recovery sheet located above the cup body generates far-infrared rays with a wavelength of 8-12 microns downward, and the food in the cup body is reflux-heated by the far-infrared rays.

[0020] The geometric center of the graphene heating sheet used in the present invention does not coincide with the geometric center of the cup body, so that heating can be effectively performed only on one side of the bottom of the cup body that deviates from the geometric center. During the heating process, the graphene heating sheet simultaneously generates far infrared rays with a wavelength of 8-12 microns.

[0021] The present invention utilizes the positional relationship between the graphene heating plate and the graphene heat recovery plate, i.e., their geometric centers do not overlap, so that they can respectively generate far-infrared rays to heat the food in the cup. Moreover, the far-infrared rays generated by the graphene heating plate generate far-infrared eddy currents in the cup, effectively performing eddy current heating on the food.

[0022] It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the embodiments and the accompanying drawings:

[0029] Example 1

[0030] refer to Figure 1-2 ,

[0031] An eccentric eddy current heater comprises a shell 1 and a cover 2 matched with the shell 1, wherein the shell 1 is provided with a handle, a holding cup 3 is provided inside the shell 1, and further comprises:

[0032] A graphene heating sheet 4 is used to heat the food in the holding cup 3. The graphene heating sheet 4 is arranged between the bottom of the housing 1 and the holding cup 3. The geometric center of the graphene heating sheet 4 does not coincide with the geometric center of the holding cup 4.

[0033] The graphene heat recovery sheet 5 is provided above the holding cup body 3 and is used to absorb the heat energy generated when the food in the holding cup body 3 is heated and radiate far infrared rays downward to heat the food in the holding cup body 3;

[0034] The area of ​​the graphene heating plate 4 is smaller than the area of ​​the graphene heat recovery plate 5 .

[0035] Furthermore, it further includes a control system (not shown) and a temperature sensor 6 , wherein the control system is used to obtain temperature information of the temperature sensor 6 and control the start or stop of the graphene heating plate 4 .

[0036] Furthermore, the graphene heating sheet 4 and the graphene heat recovery sheet 5 are circular sheet structures.

[0037] Furthermore, a wireless charging receiving plate (not shown and belongs to the prior art) is provided at the bottom of the holding cup body 3 .

[0038] Furthermore, a graphene heat recovery sheet 5 is provided at the bottom of the cover 2 .

[0039] Furthermore, the geometric center of the graphene heat recovery sheet 5 coincides with the geometric center of the containing cup 3 .

[0040] Example 2

[0041] refer to Figure 3-4The difference between this embodiment and the first embodiment is that:

[0042] Furthermore, the radius of the graphene heating plate 4 is less than half of the radius 3 of the containing cup body.

[0043] Furthermore, the horizontal distance between the centers of the graphene heating plate 4 and the graphene heat recovery plate 5 is smaller than the radius of the graphene heating plate 4 .

[0044] Working principle, reference Figure 5 The dotted arrows are the propagation direction of the far-infrared rays emitted by the graphene heat recovery plate after saturation, and the solid arrows are the propagation direction of the eddy currents generated by the graphene heating sheet. The graphene heating sheet directly heats the bottom of the cup body. At the same time, during the heating process, the food in the cup body absorbs and transfers heat upward. After absorbing heat, the graphene heat recovery sheet located above the cup body generates far-infrared rays with a wavelength of 8-12 microns downward, which reflux heat the food in the cup body. Due to the positional relationship between the graphene heating sheet and the graphene heat recovery sheet, that is, their geometric centers do not overlap, they can generate far-infrared rays separately to heat the food in the cup body. Moreover, the far-infrared rays generated by the graphene heating sheet generate far-infrared eddy currents in the cup body, effectively performing eddy current heating on the food.

[0045] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
