Referring to FIGS. 1 to 7, the heating apparatus 100 according to an embodiment of the present invention includes an induction patch 110 and a heating element 120. The heating apparatus 100 may further include a temperature sensing unit 130 and a controller 140.
In the heating apparatus 100, the induction patch 110 may be formed as a saddle of a motorcycle. If a rider gets on the motorcycle equipped with the heating element 120, the induction patch 110 charges the heating element 120 to allow the heating element 120 to generate heat. The induction patch 110 incorporates an internal coil 111.
The induction patch 110 receives a current from an external or internal power supply 10 and applies the current to the internal coil 111. Here, in a case where the power supply 10 is a DC power supply, a converter 11 for converting DC power into AC power is additionally necessary.
The induction patch 110 charges the heating element 120 using a magnetic field generated when the current flows in the internal coil 111. In a state in which the heating element 120 is not in physical contact with the induction patch 110, the heating element 120 performs charging, specifically non-contacting charging. Thus, when the induction patch 110 charges the heating element 120, the heating element 120 ensures user's safety.
The heating element 120 performs non-contacting charging in link with the induction patch 110 and generates heat. The heating element 120 is shaped of a garment, specifically, the motorcycle rider's clothes. If the motorcycle rider wearing the heating element 120 gets on the motorcycle, the induction patch 110 charges the heating element 120. In addition, the heating element 120 generates heat using the charged power. Thus, the motorcycle rider receives the heat from the heating element 120 to achieve warming.
To this end, the heating element 120 includes warps 121 and wefts 125. The warps 121 and the wefts 125 are woven to produce the heating element 120. The warps 121 and the wefts 125 are woven to be perpendicular to each other and interlaced in a zigzag fashion to form the heating element 120.
The warps 121 are formed in parallel with each other in a first direction, and include a plurality of warps arranged at constant intervals in a second direction perpendicular to the first direction. The warps 121 include a plurality of general warps 122 and conductive metal yarns 123, which are arranged in the second direction.
The warps 122 are generally formed from yarns. Here, the yarns may mean threads constituting a fabric for making clothes. FIGS. 3 to 5 illustrate that the general warps 122 have a multi-filament structure formed by twisting multiple strands of yarns into a single yarn. However, the structure of the general warps 122 is not limited to the multi-filament structure, and may be formed as a single yarn.
The conductive metal yarns 123 are formed in the first direction and are arranged in parallel with the general warps 122. One end of the conductive metal yarn 123 is formed in the shape of a coil and performs charging using a magnetic field applied from the induction patch 110. The conductive metal yarns 123 generate heat using the charged power, thereby supplying heat to a user wearing the heating element 120. While the conductive metal yarns 123 constitute part of the warps 121 in the illustrated embodiment, they may be arranged to constitute part of the wefts 125 and the shapes of the conductive metal yarns 123 are not limited to those listed herein. Each of the conductive metal yarns 123 include one or more metal parts 123a centrally positioned based on the diameter of the conductive metal yarn 123, and a coating part 123b surrounding the metal parts 123a. In addition, a void 123c that is an empty space created between the metal parts 123a and the coating part 123b when the coating part 123b is not led into a region between the metal parts 123a. A cover yarn (not shown) surrounding the outer circumferential surface of the coating part 123b may further be formed.
The metal parts 123a are made of a metal having small electrical resistance and high resilience against repeated bending processes. The metal parts 123a may be formed of at least one selected from copper, a copper alloy, silver, a silver alloy, brass, and combinations thereof. In addition, while seven of the metal parts 123a are provided in the illustrated embodiment, aspects of the present invention are not limited thereto.
The coating part 123b is formed to surrounding the metal parts 123a. The coating part 123b prevents EMI from being transferred to human body while allowing heat generated from the metal parts 123a to be transferred to the human body. In addition, the coating part 123b prevents external noise electronic waves from being transferred to the metal parts 123a within the conductive metal yarns 123. To this end, the coating part 123b may be formed of at least one material selected from ethylenetetrafluoroethylene (ETFE), fluorinated ethylenepropylene (FEP), polytetrafluoroethylene (PTFE), polyvinylidenefluoride (PVDF), perfluoroalkoxy (PFA), and equivalents thereof, but aspects of the present invention are not limited thereto.
One end of each of the conductive metal yarns 123 has a coil 123d to perform non-contacting charging using a magnetic field generated from the internal coil 111 of the induction patch 110. In addition, if a current flows in the charged conductive metal yarn 123, heat is generated through a resistive component 123e. Thus, the conductive metal yarn 123 may transfer the heat to a rider wearing the heating element 120.
The wefts 125 include a plurality of wefts formed in a second direction perpendicular to the warps 121. The plurality of wefts 125 are arranged at constant intervals in the first direction and are positioned in parallel with each other. The wefts 125 and the warps 121 are woven together to form the heating element 120. Like the general warps 121, the wefts 125 may have a single yarn structure or a multi-filament structure.
The wefts 125 are divided into two groups according the rows in which they are arranged, the two groups including first wefts 126 and second wefts 127. The first wefts 126 and the second wefts 127 are arranged to be adjacent to each other. For example, the first wefts 126 are positioned at odd rows, and the second wefts 127 are positioned at even rows.
The temperature sensing unit 130 is formed on a portion of the surface of the heating element 120. The temperature sensing unit 130 senses the temperature of the heating element 120. In addition, the temperature sensing unit 130 transmits the sensed temperature to the controller 140. Thus, the temperature sensing unit 130 allows the motorcycle rider wearing the heating element 120 to perceive the temperature. The temperature sensing unit 130 may be formed using a bimetal or thermistor for sensing the temperature of the heating element. However, the present invention does not limit the kind of the temperature sensing unit 130 to those listed herein.
The controller 140 is attached at one side of the heating element 120. The controller 140 may control a temperature signal transmitted from the temperature sensing unit 130 to be displayed on a display, and may allow the motorcycle rider to control the temperature of the heating element 120. The controller 140 may control an amount of the current flowing through the conductive metal yarns 123 by adjusting the size of a variable resistor (not shown) provided in the heating element 120. Therefore, the controller 140 may control the temperature of the heating element 120.
As described above, the heating apparatus 100 includes the heating element 120 for producing motorcycle rider's clothes by weaving the induction patch 110 formed in the saddle of the motorcycle and the conductive metal yarns 123 to allow the induction patch 110 to perform non-contacting charging on the heating element 120, thereby facilitating user's convenience. In addition, the conductive metal yarns 123 generate heat using charged power, thereby easily transmitting heat to the motorcycle rider wearing the heating element 120.
A configuration of a heating apparatus according to another embodiment of the present invention will now be described with reference to the accompanying drawings. The same functional components as those of the previous embodiment are not separately illustrated, and the following description will focus on differences between the present embodiment and the previous embodiment.
FIG. 8 illustrates an induction patch of a heating apparatus according to another embodiment of the present invention.
Referring to FIG. 8, the heating apparatus 200 according to another embodiment of the present invention includes an induction patch 210, and a heating element (not shown). The heating apparatus 200 according to another embodiment of the present invention may further include a temperature sensing unit (not shown) and a controller (not shown).
In the heating apparatus 200 according to another embodiment of the present invention, the induction patch 210 may be formed as a sheet of a chair. If a user with the heating element sits down on the chair, specifically, the induction patch 210, the induction patch 210 charges the heating element to allow the heating element to generate heat. To this end, the induction patch 210 incorporates an internal coil and applies a current from an external or internal power supply to the internal coil to generate a magnetic field. In addition, the heating element 120 and the induction patch 110 perform non-contacting charging. Thus, when the induction patch 110 charges the heating element 120, safety of the user with the heating element 120 can be facilitated.
FIG. 9 illustrates an induction patch of a heating apparatus according to still another embodiment of the present invention, and FIG. 10 illustrates a heating element of a heating apparatus according to another embodiment of the present invention.
Referring to FIGS. 9 and 10, the heating apparatus 300 according to still another embodiment of the present invention includes an induction patch 310 forming handles of a bicycle, and a heating element 320 forming gloves. The heating apparatus 300 may further include a temperature sensing unit (not shown), and a controller (not shown).
The induction patch 310 may be formed as handles of a bicycle. If a user wearing the glove-shaped heating element 320 holds the charging patch 310, the induction patch 310 charges the heating element 320 to allow the heating element 320 to generate heat. To this end, the charging patch 310 incorporates an internal coil and applies a current from an external or internal power supply to the internal coil to generate a magnetic field. In addition, the heating element 320 and the induction patch 310 perform non-contacting charging.
The heating element 320 is formed using conductive metal yarns and shaped of gloves. If a user wearing the glove-shaped heating element 320 in his/her hands holds the induction patch 310, the heating element 320 and the induction patch 310 perform non-contacting charging. In addition, the heating element 320 applies a current to the conductive metal yarns using the charged power and generates heat. Therefore, the heating element 320 applies the heat to the hands of the user wearing the heating element 320, thereby achieving hand warming.
FIG. 11 illustrates an induction patch and a heating element of a heating apparatus according to another embodiment of the present invention.
Referring to FIG. 11, the heating apparatus 400 according to another embodiment of the present invention includes an induction patch 410 and a heating element 420. The heating apparatus 400 may further include a temperature sensing unit (not shown) and a controller (not shown).
The induction patch 410 may be formed as a curtain rod. When the heating element 420 moves to the center of the curtain rod, the induction patch 410 performs non-contacting charging on the heating element 420. To this end, the induction patch 410 incorporates an internal coil. Thus, if a curtain having the heating element 420 is drawn to shield the sun light, that is to say, if the heating element 420 moves to the center of the induction patch 410 along the curtain rod, the induction patch 410 applies a current to the internal coil. Thus, a magnetic field is generated from the induction patch 410, and the heating element 420 performs non-contacting charging using the induction patch 410.
The heating element 420 is formed into a curtain by weaving conductive metal yarns. When the curtain having the heating element 420 is drawn, the heating element 420 performs non-contacting charging using the magnetic field generated from the induction patch 410. In addition, the heating element 420 applies a current to the conductive metal yarns using charged power and generates heat. In addition, when the curtain formed using the heating element 420 is drawn, the heating element 420 is separated from the induction patch 410 so as not to perform non-contacting charging, thereby preventing the heating element 420 from generating heat.
While this invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, rather is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
