Figure 1 illustrates an embodiment of a magnetic field-applied heating mat according to the present invention.

Referring to FIG. 1, a magnetic field-applied heating mat includes a controller (11) for operation control; a current waveform generation module (12) that generates a current waveform under the control of the controller (11); at least one loop antenna (13) that generates a magnetic field by inducing a current generated by the current waveform generation module (12) and thereby generates heat; and a control sheet (14) that adjusts a wavelength of a heat ray such as a thermal resistance or infrared ray while being received by the loop antenna (13).

The entire operation can be controlled or regulated by the controller (11), and the controller (11) can have a function of controlling whether a magnetic field is generated, the size of the applied magnetic field, and the temperature generated according to the generation of the magnetic field based on the detection information by the detection means. The controller (11) can have various electronic or mechanical structures for controlling the entire operation of the heating mat, and the present invention is not limited thereby. The operation of the current waveform generation module (12) can be controlled by the controller (11). The current waveform generation module (12) has a function of determining the waveform of the current for inducing the magnetic field. For example, a current in the form of a pulse can be created by the current waveform generation module (12), and the size of the pulse or the duration of the pulse can be determined. In addition, the waveform of the pulse or the pulse application period can be determined by the current waveform generation module (12). The current generated by the current waveform generation module (12) can be induced to the loop antenna (13), and a magnetic field can be generated by the loop antenna (13) and induced to the human body. The loop antenna (13) may have a structure extending outward in a spiral shape from the center as a whole. The loop antenna (13) may have a function of generating a magnetic field by inducing a flow of pulse current or pulse direct current and a function of controlling the temperature of the heating mat by generating heat by the flow of current. It is advantageous that the magnetic field be applied to the human body at an appropriate temperature, and the temperature of the human body or the surroundings of the human body may be appropriately maintained by the heat generated by the loop antenna (13). The loop antenna (13) may be accommodated inside the adjustment sheet (14), and the human body may be positioned on the upper surface of the adjustment sheet (14). The magnetic field and heat generated from the loop antenna (13) may pass through the adjustment sheet (14) so that the level of penetration and wavelength of heat rays or infrared rays may be controlled and applied to the human body. Specifically, the adjustment sheet (14) may have a function of controlling the level of penetration of heat rays such as infrared rays or the wavelength of infrared rays. For example, the control sheet (14) may include at least one selected from the group consisting of tourmaline, illite, jade, and germanium in an amount of at least 1 wt% based on the total weight of the control sheet (14). Tourmaline may have electrical properties and may promote blood circulation, activate cells, promote metabolism, activate gastrointestinal movement, or have various beneficial effects on the human body. Illite has the function of removing heavy metals or harmful gases while radiating a large amount of far-infrared rays. Jade may have the effect of emitting circulating energy of the human body to facilitate metabolism and blood circulation. In addition, germanium may have the function of alleviating pain, having an antiviral effect, or having an anion effect while promoting metabolism. Such functional materials may be impregnated in a powder form into a control sheet (14) made of cotton, synthetic resin, or natural fiber, or may be added during the manufacturing process of the control sheet (14), or may be included in the control sheet (14) in a similar manner. The functional material may be at least 1 wt%, preferably 1 to 10 wt%, and most preferably 1 to 5 wt%, based on the total weight of the control sheet (14), but is not limited thereto. The control sheet (14) may also include at least 1 wt% of a ferrite material in a powder form or a similar form.

The control sheet (14) may include various materials that are activated by the induction of an electromagnetic field to produce a beneficial effect on the human body. In addition, the control sheet (14) may have various layer structures of metal or non-metal materials, and the present invention is not limited thereby.

The detection unit (15) can detect the size of the magnetic field applied to the human body, the state of the human body, the temperature of the human body, or the ambient temperature. The detection unit (15) can be placed on the adjustment sheet (14) or mounted in a non-contact manner, and can be connected to the operation data module (16) so as to be able to communicate with it wirelessly or by wire. The operation data module (16) can generate and store operation data for a waveform to be generated by the current waveform generation module (12). The operation data generated by the operation data module (16) can be transmitted to the current waveform generation module (12). The current waveform generation module (12) can generate a current waveform based on the operation data. When the information detected by the detection unit (15) is transmitted to the operation data module (16), the operation data module (16) can analyze the detection information to determine whether the current operation data is appropriate. If the operation data needs to be modified according to the detection information, modified operation data can be generated and transmitted to the current waveform generation module (13). And the current waveform generation module (13) can determine the current waveform according to the modified operation data. The current waveform generation module (13) can determine the current waveform in various ways, and the present invention is not limited thereby.

Each loop antenna (23a, 23b, 23c) may be connected to an operating module (22) by an inductive wiring (231a, 231b, 231c), and when a plug (P) is connected to a power source, power may be supplied to each loop antenna (23a, 23b, 23c) under the control of the operating module (22). The power can be direct current or low frequency alternating current or pulsed direct current, and each loop antenna (23a, 23b, 23c) can be independently controlled by the operating module (22). The operating status of each loop antenna (23a, 23b, 23c) can be detected by the detection unit (15a, 15b, 15c). For example, the size or temperature of the magnetic field generated from each loop antenna (23a, 23b, 23c) can be detected by the detection unit (15a, 15b, 15c) and transmitted to the detection processing module (24). The detection processing module (24) can process the information transmitted from each detection unit (15a, 15b, 15c) and transmit it to the analysis module (25). The analysis module (25) can analyze the status information of each loop antenna (23a, 23b, 23c) to determine whether each loop antenna (23a, 23b, 23c) is operating within a predetermined range. Then, the analysis result can be transmitted to the operation data module (26). The operation data module (26) can modify the operation data according to the analysis result, and the modified operation data can be transmitted to the current control module (26). The current control module (26) can control the current induced to the loop antennas (23a, 23b, 23c) based on the transmitted operation data so that a magnetic field within a predetermined range is induced in each loop antenna (23a, 23b, 23c) and each loop antenna (23a, 23b, 23c) can be operated within a predetermined temperature range.

In addition, the pulse generation module (32) may be connected to a power supply means (33). A current pulse as shown on the right side of FIG. 2 may be generated by the pulse generation module (22). The current pulse may be in the form of a pulse having at least one positive size during one period (T). A plurality of pulses applied to one period (T) may have different sizes, and the respective forms of the plurality of pulses may be determined by the size of a magnetic field to be generated or a temperature range to be controlled. Preferably, the pulse may be applied so that a magnetic field control section (BC) and a temperature control section (TC) are formed in one period. Specifically, in the magnetic field control section (BC), a plurality of pulses of the same shape with relatively large amplitudes can be applied. A magnetic field is generated by the pulses applied in the magnetic field control section (BC), and when applied to the human body, the temperature of the loop antenna (23a) can rise. In addition, in the temperature control section (TC), pulses with relatively small amplitudes are intermittently applied so that the temperature rise is controlled and the effect of applying the magnetic field is increased. The size of the pulse, the duration, the number of pulses included in one cycle, or the shape of the pulses generated in one cycle can be determined in various ways, and the present invention is not limited thereby.
