Description

Fire prevention mats

[0001] The present invention relates to a fire prevention mat, and more particularly, to a fire prevention mat which is composed of a plurality of conductive lines, and in which the conductive line strands located at the upper and lower ends are split to form branched conductive lines in which the plurality of conductive line strands branch from each other, and in which the branched conductive lines formed at opposite positions among the branched conductive lines are connected to each other so that all of the plurality of conductive lines conduct electricity, thereby maximizing the contact area between the plurality of conductive lines and the heating line, thereby preventing poor contact with the heating line from occurring, and in which even if some of the conductive line strands are damaged or broken, the mat can prevent a fire from occurring due to poor contact with the heating line.

[0002] A typical heated mat includes a heating mat that generates heat when power is applied, and is used in various fields such as being applied to mattresses for sleeping or installed on vehicle seats.

[0003] These heating mats are composed of heating wires for heating, and since most of the heating wires use copper (copper wire), problems such as short circuits due to hardening caused by continuous heat switching or oxidation of the copper may occur, and this may cause poor contact with power lines and short circuits due to poor contact.

[0004] In particular, the copper used in the heating mat according to the prior art was woven into the fabric of the mat, such as a thin non-woven fabric or similar sheet, with serial wiring, which caused abnormal overheating due to the phenomenon of the heating wires bunching or overlapping.

[0005] Accordingly, a heating mat was developed that consists of a heating wire made of carbon fiber and a copper wire that supplies power to the heating wire. However, in the case of the carbon fiber heating wire according to the prior art, not only was sufficient heating power not secured due to the heating limit of carbon fiber, but its tensile strength was weak, so it was easy to break.

[0006] In addition, there was a problem that when the heating mat was used repeatedly, the copper wire would separate from the mat's fabric, causing poor contact with the heating wire. If a short circuit or fire due to poor contact between the copper wire and the heating wire occurred, damaging or destroying part or all of the mat, this not only seriously lowered the reliability of the product, but also caused problems such as not being able to provide safety.

[0007] In addition, in the case of a conventional heating mat, if some of the copper conductive wires are damaged or broken due to external force such as long-term use or impact, the resistance is concentrated in the remaining conductive wires, causing a rapid localized phenomenon, and the localized heating causes burns to the user or causes a fire, resulting in a decrease in product reliability and serious safety issues.

[0008] In addition, the heating mat according to the prior art had the problem of being difficult to clean through general washing methods, such as water washing or hand washing, because some of the conductive strands were at risk of being damaged or broken, and had the problem of being vulnerable to stress that occurred during repeated use.

[0009] There was a problem that caused an increase in management costs, such as the cost of maintaining and repairing the product when a fire occurred in a heating mat according to this conventional technology, resulting in damage or destruction of the product.

[0010] In order to solve such a problem, the present invention has been devised by the background art described above, and is composed of a plurality of conductive lines, and the conductive line strands located at the upper and lower ends are split to form branched conductive lines in which the plurality of conductive line strands branch from each other, and the branched conductive lines formed at opposite positions among the branched conductive lines are connected to each other so that all of the plurality of conductive lines are configured to conduct electricity, thereby maximizing the contact area between the plurality of conductive lines and the heating line, thereby preventing poor contact with the heating line, and also providing a fire prevention mat that can prevent a fire from occurring due to poor contact with the heating line even if some of the conductive line strands are damaged or broken.

[0011] In addition, the present invention is configured such that a plurality of conductive lines are all energized by branch conductive lines, so that even if only one of the branch conductive lines maintains contact with the heating line, stable and continuous power supply is possible, thereby preventing overheating from occurring due to concentration of resistance on the side of the conductive line where poor contact has occurred, and thereby providing a fire prevention mat capable of preventing the occurrence of a fire.

[0012] In addition, the present invention aims to provide a fire prevention mat that can prevent oxidation of a conductive wire that supplies power to a heating wire by coating tin on the surface of copper having a thin diameter.

[0013] In addition, the present invention provides a fire prevention mat in which a plurality of conductive wires coated with tin are connected to each other by branch conductive wires to form a single integrated conductive wire, thereby providing sufficient resistance to stress due to repeated use, and also minimizing the rate of product defects by improving the weaving properties with the base fabric of the mat, and minimizing damage or breakage of the conductive wires even when washed using general washing methods such as hand washing or water washing.

[0014] According to one embodiment of the present invention for achieving such a task, it is characterized by including: a base fabric (110) equipped with a control device (140) for controlling whether or not to supply direct current power; a plurality of heating wires (120) connected to the base fabric (110) and generating heat when power is applied; and an electrode part (202) including a plurality of conductive wires (250) configured to make electrical contact with the heating wires (120), and a plurality of branched conductive wires (260) formed on the plurality of conductive wires (250), which split and branch the copper wires formed on the plurality of conductive wires (250) into predetermined strands and connect the branched plurality of conductive wires (250) to each other so that they can conduct current.

[0015] According to one embodiment of the present invention, the electrode part (202) is characterized by including a first electrode part (210) which is formed by the plurality of conductive lines (250) and the plurality of branch conductive lines (260), is formed in the central portion of the base fabric (110), and is configured to be in contact with the central portion of the heating line (120), a second electrode part (220) which is formed on one side or both sides of the base fabric (110), or is formed on the peripheral surface, and is configured to be in contact with both ends of the heating line (120), and a plurality of first insulating cover parts (230) which are formed in the first electrode part (210), and are formed at a position where the heating line (120) and the plurality of conductive lines (250) come into contact, and fix the first electrode part (210) to the base fabric (110).

[0016] According to one embodiment of the present invention, the electrode portion (202) is characterized by including a plurality of conductive lines (250) and a plurality of branch conductive lines (260), and a second insulating cover portion (240) configured between the plurality of first insulating cover portions (230) and providing insulation for a current flowing through the first electrode portion (210).

[0017] According to one embodiment of the present invention, the plurality of conductive lines (250) are characterized in that they are composed of a plurality of tin-coated copper lines.

[0018] According to one embodiment of the present invention, the branch conductive line (260) is characterized in that it branches from each of the plurality of conductive lines (250) and branches into a first branch conductive line (260a) and a second branch conductive line (260b).

[0019] According to one embodiment of the present invention, the first insulating cover part (230) includes an electrode contact part (310) that allows the heating line (120) and the plurality of conductive lines (250) to be in electrical contact while being perpendicular to each other, a first electrode covering part (320) that is respectively formed on the upper and lower portions of the electrode contact part (310) and covers the heating line (120) and the plurality of conductive lines (250) so as to surround them, a branch conductive line connecting part (330) that is respectively formed on the upper and lower portions of the first electrode covering part (320) and connects the plurality of branch conductive lines (260) formed on the plurality of conductive lines (250), and a second electrode that is respectively formed on the upper and lower portions of the branch conductive line connecting part (330) and covers the plurality of conductive lines (250) extending from the ends of the plurality of branch conductive lines (260). It is characterized by further including a covering portion (340).

[0020] According to one embodiment of the present invention, the second insulating cover part (240) is characterized by including a first electrode covering part (320) that covers the heating line (120) and the plurality of conductive lines (250) so as to surround them, and a second electrode covering part (340) that is formed at the lower portion of the first electrode covering part (320) and covers the plurality of conductive lines (250) that extend from the ends of the plurality of branch conductive lines (260) so as to surround them.

[0021] According to an embodiment of the present invention, since a plurality of conductive lines are configured to be all electrically conductive by branch conductive lines, the contact area between the plurality of conductive lines and the heating line is maximized, thereby preventing poor contact with the heating line from occurring. In addition, even if some of the conductive line strands are damaged or broken, there is an effect of preventing a fire from occurring due to poor contact with the heating line.

[0022] In addition, according to an embodiment of the present invention, since a plurality of conductive lines are configured to be all energized by branch conductive lines, even if only one of the branch conductive lines maintains contact with the heating line, stable and continuous power supply is possible, thereby preventing overheating from occurring due to concentration of resistance on the side of the conductive line where poor contact has occurred, thereby having the effect of preventing fire from occurring.

[0023] In addition, according to an embodiment of the present invention, by coating tin on the surface of copper having a thin diameter, there is an effect of preventing oxidation of a conductive wire that supplies power to a heating wire.

[0024] In addition, according to an embodiment of the present invention, since a plurality of conductive wires coated with tin are connected to each other by branch conductive wires and formed into a single integrated conductive wire, sufficient resistance to stress due to repeated use can be provided, and not only can the weaving with the base fabric of the mat be improved to minimize the rate of product defects, but even when washing is performed using general washing methods such as hand washing or water washing, damage or breakage of the conductive wires can be minimized.

[0027] FIG. 3 is a drawing showing an enlarged view of part “A” according to one embodiment of the present invention.

[0028]

[0029] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0030] As illustrated, the fire prevention mat of the present invention comprises a conventional sleeping mat, an electric heating mat laminated on a bed mattress to provide heat, or a heating (or heating) sheet built into a car seat, and is configured to include a mat portion (100) and a heating sheet portion (200).

[0031] The mat portion (100) is woven so that ordinary fibers are orthogonal to each other, and is composed of a base fabric (110) to which a heating sheet portion (200) is combined, a plurality of heating lines (120) that are woven together with the base fabric (110) so as to be electrically connected to the heating sheet portion (200), and which generate heat when power is applied, and a control device (140) that controls whether power is supplied to the heating lines (120).

[0032] The base fabric (110) is configured with a second electrode part (220) formed along the circumference of the heating sheet part (200), and a closing part (112) is formed to support the second electrode part (220) and the heating wire (120) so that they can be electrically connected to each other.

[0033] At this time, the closing part (112) may be composed of the same material as the base fabric (110), and may be configured so that the ends of the second electrode part (220) and the heating wire (120) can be electrically connected to each other inside thereof, so that the ends of the second electrode part (220) and the heating wire (120) are not exposed to the outside, but is not limited thereto.

[0034] That is, the second electrode part (220) is configured to be joined by weaving to the upper surface of the closing part (112), and when the second electrode part (220) is joined, the heating wire (120) may also be configured to be joined by weaving.

[0035] In addition, an electrode finishing portion (130) is formed on the base fabric (110) at a finishing portion (112), preferably formed at a portion where the first and second electrode portions (210, 220) forming the heating sheet portion (200) are grounded (or in contact) with each other, thereby connecting the first and second electrode portions (210, 220) to the base fabric (110).

[0036] At this time, the electrode finishing part (130) may correspond to the part where the first and second electrode parts (210, 220) are joined by weaving on the finishing part (112).

[0037] The heating wire (120) is configured in multiple pieces spaced apart at a predetermined interval on the upper surface of the base fabric (110), and is configured to be arranged in parallel at a predetermined interval on the base fabric (110), and is configured so that both ends thereof are electrically connected to the first and second electrode parts (210, 220) configured in the heating sheet part (200), and is configured so that heating is generated by power applied to the first and second electrode parts (210, 220).

[0038] These heating wires (120) may be made of carbon fiber. However, they are not limited thereto, and may be formed in a double covering form in which a pair of silver-coated fibers are crossed over each other.

[0039] Here, double covering means that a silver-coated yarn is wound clockwise around the outer surface of the heating wire (120), and another silver-coated yarn is wound counterclockwise so as to intersect with each other and wrap around the outer surface of the heating wire (120).

[0040]

[0041] The heating sheet part (200) is configured to heat the heating wire (120) as the current applied from the control device (140) flows, and is configured to be woven into the base fabric (110), and is configured to be in contact with the heating wire (120), but is configured to be connected to each other while branching the contact portion with the heating wire (120), a first electrode part (210) configured on one side or both sides of the base fabric (110), or configured on the peripheral surface, and configured to be in contact with both ends of the heating wire (120), a first insulating cover part (230) configured on the first electrode part (210), but is configured at a position where contact is made with the heating wire (120), and fixes the first electrode part (210) to the base fabric (110) and provides insulation against the current flowing through the first electrode part (210), and a first insulating It is configured between the cover portions (230), and includes a second insulating cover portion (240) that fixes the first electrode portion (210) to the base fabric (110) and provides insulation for the current flowing through the first electrode portion (210).

[0042] The first electrode part (210) is woven and connected to the base fabric (110), and is formed in the central portion of the base fabric (110) and is configured to make contact with the central side of the heating wire (120), so that the heating wire (120) is heated by the current applied from the control device (140).

[0043] At this time, in the present invention, the first electrode portion (210) is described as being formed in the central portion of the base fabric (110), but it is not limited thereto, and may be formed in one side of the base fabric (110) depending on the size of the base fabric (110), that is, the size or area of ​​the fire prevention mat.

[0044] Here, when the first electrode part (210) is configured on one side of the base fabric (110), the second electrode part (220) may be configured at a position facing the first electrode part (210) so that both ends of the heating wire (120) are in contact with each other.

[0045] This first electrode part (210) is composed of a copper wire (or copper thread) with tin coated on the surface, and is composed of a plurality of conductive lines (250) configured to be spaced apart at fine intervals, and a plurality of branched conductive lines (260) that split the plurality of conductive lines (250) into a certain number of strands to branch them and connect the branched plurality of conductive lines (250) to each other.

[0046] At this time, the conductive line (250) may be formed of a plurality of copper wires coated with tin, and since the conductive line (250) is formed of a plurality of copper wires, the contact area with the heating line (120) can be improved, thereby preventing poor contact with the heating line (120).

[0047] For example, one of the plurality of conductive lines (250) of the present invention may be formed of 32 tin-coated copper wires. However, this is not a limitation, and the number of copper wires forming one conductive line (250) may vary depending on the size and location of the fire prevention mat.

[0048] The branch conductive line (260) is formed on each of the plurality of conductive lines (250) and is formed at a position spaced apart by a predetermined distance from the portion in contact with the heating line (120). The branch conductive line (260) divides the copper wires forming the plurality of conductive lines (250) into a predetermined number of strands to branch them and connects the branched copper wires to each other so that all of the plurality of conductive lines (250) can be maintained in a state of being energized, thereby maximizing the contact area between the plurality of conductive lines (250) and the heating line (120) to prevent poor contact with the heating line (120) from occurring, and even if some or most of the copper wires forming the plurality of conductive lines (250) are damaged or broken, it serves to prevent a fire from occurring due to poor contact with the heating line (120).

[0049] These branch conductive lines (260) are configured so that when connecting a plurality of conductive lines (250), the branch conductive lines (260) formed at opposing positions are connected to each other.

[0050] That is, as illustrated in FIG. 3, the branch conductive line (260) branches off from the conductive line (250) and branches off into a first branch conductive line (260a) and a second branch conductive line (260b). In this way, among the plurality of conductive lines (250) branched off into the first and second branch conductive lines (260a, 260b), when the first conductive line (250a) and the second conductive line (250b) are connected, the second branch conductive line (260b) formed on the first conductive line (250a) is connected to the first branch conductive line (260a) formed on the second conductive line (250b).

[0051] Meanwhile, in the case where the branch conductive line (260) of the present invention is made of 32 tin-coated copper wires as in the example described above, the first and second branch conductive lines (260a, 260b) can be formed of 16 copper wires each, but are not limited thereto.

[0052] The present invention configured as described above can maintain a state in which a plurality of conductive lines (250) are connected to each other by a branch conductive line (260), and since the plurality of conductive lines (250) connected by the branch conductive line (260) are configured to be integrated with each other, even if a short circuit occurs in a plurality of copper lines among the copper lines forming the conductive line (250) and poor contact with the heating line (120) occurs, the flow of current applied by other copper lines that are stably maintaining contact with the heating line (120) can be maintained.

[0053] That is, since a plurality of conductive lines (250) are independently formed and woven into the base fabric (110), some of the plurality of copper wires forming the conductive lines (250) are disconnected, resulting in poor contact with the heating wire (120), and when only a small number of copper wires remain in contact with the heating wire (120), resistance is concentrated in the small number of copper wires, which causes overheating and is transferred to the disconnected copper wires, thereby solving the conventional problem of causing a fire.

[0054] Meanwhile, the second electrode portion (220) of the present invention is formed on the finishing portion (112) of the base fabric (110) and is configured so that the end of the heating wire (120) can be in contact with it, and is configured to have the same shape as the first electrode portion (210) described above.

[0055] That is, the second electrode part (220) is also composed of a copper wire (or copper thread) with tin coated on the surface, and is composed of a plurality of conductive lines (250) configured to be spaced apart at fine intervals, and a plurality of branched conductive lines (260) that split the plurality of conductive lines (250) into a certain number of strands and connect the branched plurality of conductive lines (250) to each other.

[0056] The first insulating cover part (230) is a component that is configured in the electrode part (202) including the first electrode part (210) or the first and second electrode parts (210, 220), supports electrical contact between the heating wire (120) and a plurality of conductive lines (250), and provides insulation to the electrode part (202) by covering the plurality of conductive lines (250) so as to surround them, and at the same time covers the connection portions of branch conductive lines (260) formed for each of the plurality of conductive lines (250), thereby enabling bonding with the base fabric (110).

[0057] These first insulating cover parts (230) may be configured in multiple pieces spaced apart at a predetermined interval along the electrode part (202), and may be configured to be perpendicular to the heating line (120) arranged in parallel to the base fabric (110).

[0058] As shown in FIGS. 2 and 3, the first insulating cover part (230) is configured to include an electrode contact part (310) in which a heating line (120) is arranged to be perpendicular to a plurality of conductive lines (250), a space is provided so that the heating line (120) and the plurality of conductive lines (250) can make electrical contact, a first electrode covering part (320) which is formed on the upper and lower portions of the electrode contact part (310), and which covers the plurality of conductive lines (250) that are in electrical contact with the heating line (120) and is fixed to the base fabric (110), and a branch conductive line connecting part (330) which is formed on the upper and lower portions of the first electrode covering part (320), and which connects a plurality of branch conductive lines (260) formed on the plurality of conductive lines (250) so that the plurality of conductive lines (250) can be integrated with each other.

[0059] In addition, the first insulating cover part (230) may further include a second electrode covering part (340) configured to cover a plurality of conductive lines (250) extending from the end of the branch conductive line (260) and configured to be formed on the upper and lower portions of the branch conductive line connection part (330), to secure the plurality of conductive lines (250) to the base fabric (110), and to provide insulation for current flowing through the plurality of conductive lines (250).

[0060] In addition, the first insulating cover part (230) of the present invention may be made of a mixed yarn in which elastic yarns such as carbon fiber yarn, spandex yarn, and high-elasticity urethane yarn are mixed, and is configured to wrap the electrode part (202), and both ends thereof are formed by weaving together on the base fabric (110).

[0061] The first insulating cover part (230) of the present invention configured in this manner enables easier and better contact between the base fabric (110) and the heating wire (120), maximizes electrode contact points with the electrode part (202), and stably maintains an electrical connection state.

[0062] In addition, it is possible to provide structural stability between the electrode portion (202) and the base fabric (110), thereby providing resistance to stress from repeated loads that occur when the fire prevention mat of the present invention is repeatedly used, and thus, even when washing is performed using a general washing method such as hand washing or water washing, damage or breakage of the conductive wires can be minimized.

[0063] The second insulating cover part (240) is configured between a plurality of first insulating cover parts (230), and covers the electrode part (202) including the first and second electrode parts (210, 220) which are composed of a plurality of conductive lines (250) and branch conductive lines (260) arranged between the first insulating cover parts (230), and serves to fix the electrode part (202) to the base fabric (110) and provide insulation for the current flowing through the electrode part (202).

[0064] This second insulating cover part (240) may be composed of first and second electrode covering parts (320, 340) formed on the first insulating cover part (230).

[0065] That is, the second insulating cover part (240) is composed of a first electrode covering part (320) that covers the heating line (120) and a plurality of conductive lines (250), and a second electrode covering part (340) that is formed at the lower part of the first electrode covering part (320) and covers a plurality of conductive lines (250) that extend from the ends of a plurality of branch conductive lines (260).
