However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.
[0026] The connections mentioned in the present invention are divided into fixed connections and detachable connections. The fixed connections (i.e., non-detachable connections) include but are not limited to conventional fixed connection methods such as hemming connection, riveting connection, bonding connection and welding connection, etc. The detachable connections include but are not limited to conventional disassembly methods such as threaded connection, snap connection, pin connection and hinge connection, etc. When the specific connection method is not clearly defined, it is defaulted that at least one connection method can always be found among the existing connection methods to achieve this function, and those skilled in the art can choose according to their needs. For example: welding connection is selected for fixed connection, and hinge connection is selected for detachable connection.
[0027] In the present invention, unless otherwise clearly specified and defined, terms such as "installation", "connection", "linkage", "fixation" and the like shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral body; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0028] Example 1, in combination with Figures 1-4 To illustrate this embodiment, a kind of rare earth magnetic heating device of this embodiment includes a first arc heating body 1, a second arc heating body 2 and a connecting member 3. The first arc heating body 1 and the second arc heating body 2 can be used independently or assembled through the connecting member 3 to form a cooperative heating system;
[0029] The first arc heating body 1 includes a first high-temperature resistant and anti-corrosion layer 11, a first fireproof, heat-insulating and heat-preserving layer 12, a high-temperature resistant insulating layer 13, an electromagnetic coil 14 and an electromagnetic coil fixing frame 15. The electromagnetic coil 14, the high-temperature resistant insulating layer 13, the first fireproof, heat-insulating and heat-preserving layer 12 and the first high-temperature resistant and anti-corrosion layer 11 are sequentially arranged on the electromagnetic coil fixing frame 15;
[0030] The second arc heating body 2 includes a laser polishing surface layer 21, a nano-insulating base layer 22, a second high-temperature resistant and anti-corrosion layer 23, a first mica insulating layer 24, a graphene printing coating 25, a nano heat-preserving layer 26 and a second mica insulating layer 27 which are sequentially arranged. A power supply terminal 5 is arranged on the second mica insulating layer 27, and the power supply terminal 5 is connected to the graphene printing coating 25.
[0031] When the first arc heating body 1 and the second arc heating body 2 are combined and installed through the connecting piece 3 to form a cooperative heating system, both the first arc heating body 1 and the second arc heating body 2 are installed on the body frame. The first arc heating body 1 is arranged at the front end and is used to receive the linen with high humidity and low temperature. The second arc heating body 2 is arranged at the rear end and is used to receive the linen dried by the first arc heating body 1. The first arc heating body 1 generates heat by itself under the action of the electromagnetic field of the electromagnetic coil 14. The purpose of arranging the first arc heating body 1 heated by the electromagnetic coil and the second arc heating body 2 heated by graphene in the front and back is to better improve the drying effect of the linen. The just-placed linen has a low temperature and high humidity. The characteristics of flexible temperature control mode and magnetic field induction heating of the electromagnetic coil 14 can better pre-dry the linen with higher humidity. The electromagnetic coil 14 quickly raises the temperature to dry the linen with high humidity. After the linen is dried for a certain time, it is put into the second arc heating body 2. The graphene printing coating 25 in the second arc heating body 2 is electrified, and the graphene radiates heat to heat the drying area. The heating power is moderate and the temperature is stable to completely dry the linen. Under the condition of complementary dual-mode temperature control, the thermal response time is shortened by 60%, the linen ironing efficiency is increased by 40%, the carbon emission is reduced by the electric heating method, and the energy cost is reduced by 30%.
[0032] The bottom of the electromagnetic coil 14 is fixed by the electromagnetic coil fixing bracket 15. The high-temperature resistant insulating layer 13, the first fireproof heat-insulating and heat-preserving layer 12, and the first high-temperature resistant and anti-corrosion layer 11 arranged above the electromagnetic coil 14 are used to reduce the heat consumption and heat loss and reduce the heat loss. Similarly, the nano heat-insulating layer 26 below the graphene printing coating 25 and the second high-temperature resistant and anti-corrosion layer 23 above the graphene printing coating 25 also play the same role.
[0033] The first arc heating body 1 uses a carbon steel substrate, the number of turns of the electromagnetic coil is 120, and it is connected to the PID temperature controller. The second arc heating body 2 uses a stainless steel substrate, the thickness of the graphene printing coating 25 is 50μm, and the temperature control accuracy is ±1°C.
[0034] The heating body fixing fulcrums 4 on the first arc heating body 1 and the second arc heating body 2 have the same function, and they are all the connection points between the arc heating body and the body frame to ensure the stable effect of the first arc heating body 1 and the second arc heating body 2 after installation.
[0035] Example 2, combined with Figures 1-4 To illustrate this embodiment, the difference between a graphene-magnetic heating device in this embodiment and that in Example 1 is that the first arc heating body 1 uses a stainless steel substrate, the second arc heating body 2 uses a carbon steel substrate, the first arc heating body 1 and the second arc heating body 2 are arranged in a way of being stacked up and down, the thickness of the graphene printing coating 25 is 80μm, and the power of the electromagnetic coil 14 is dynamically adjusted to be suitable for use in a high-humidity environment.
[0036] Example 3, in combination with Figures 5-6 To illustrate this example, an en-magnetic heating device in this example, the graphene printed coating 25 includes a first graphene coating 29 and a second graphene coating 30. The first graphene coating 29 is a small graphene coating with a power of 500W, and the second graphene coating 30 is a large graphene coating with a power of 1000W. The first graphene coating 29 and the second graphene coating 30 are arranged horizontally and staggered. There is an expansion joint 31 between the first graphene coating 29 and the second graphene coating 30. The horizontal distance of the expansion joint 31 is greater than 5mm to prevent the graphene coating from being affected by heating expansion and affecting its flatness. There is also the same expansion joint 31 between the vertical graphene coatings, and the distance of the expansion joint 31 is also greater than 5mm. Wiring posts 28 are arranged on the graphene printed coating 25, and the wiring posts 28 are connected to the power supply wiring posts 5 for supplying power to the graphene printed coating 25.
[0037] This example is only an exemplary illustration of the present invention and does not limit its protection scope. Those skilled in the art can also make partial changes to it, as long as they do not exceed the spiritual essence of the present invention, they are within the protection scope of the present invention.
