Description

  The present invention relates to a heating piece structure sewn to clothing, and more particularly to a heating piece structure that obtains a high heat generation effect by being stably attached.

  In general, clothing is worn to keep the body warm, but when the temperature is low, it is common to wear large, thick and heavy clothing to warm the body. Various problems may occur during storage. Some manufacturers provide heat sources using portable disposable warmers, warmers, and warming bags, but these warmths only have the function of heating the local area of the body, so the temperature cannot be adjusted and the warming time is also long. It is short and cannot provide the necessary warming effect for people.

  As shown in Patent Document 1, the electric thermal member of Patent Document 1 is mainly provided with a plurality of heat-generating wires between two cloth bodies, and a hot-melt adhesive is applied to an appropriate portion of the wire. Although the wire is fixed to the cloth body, this method requires extra production time and labor, and there is a risk that human costs and production time may increase. A hot-melt adhesive with a low melting point that uses a hot-melt bonding method is easy to melt when the heating wire generates heat, so that the stability of the adhesive is not preferable, and the heating wire uses a hot-melt paste. Apart from fixing, there is no need to separate them. For this reason, if the heating wire is melted or washed with the hot melt paste and the heating wire is detached from the cloth body, the heating wire cannot be evenly arranged in the cloth body, and the heat supply effect is greatly increased. May be impaired.

  As shown in Patent Document 2, a heating pad having a phase change material of Patent Document 2 includes an envelope and a heated metal piece disposed in the envelope. Since the envelope and the heated metal piece are bonded with a hot-melt paste having a low melting point, the fixing property is not ideal when the hot-melt paste is melted by heat. After the hot-melt paste is melted, the opening of the envelope is opened, and there is a possibility that the heated metal piece may be damaged by being launched when washing.

  As shown in Patent Document 3, the electrical heating wire assembly of Patent Document 3 is attached with a needle-like terminal attached to one end of a heat conducting wire and a needle-like terminal and a plurality of heating wires inserted. Then, the outer sides of the needle-like terminal and the plurality of heating wires are covered and fixed by a metal cover. Since the needle-shaped terminal is in contact with some internal heating lines, most of the external heating lines are not in contact with the needle-shaped terminals. In this way, if the resistance of the part is too large and the heat conducting wire is energized to generate heat, a high-temperature “hot spot” is generated in the part due to the current, and the current cannot be passed through the entire heating line. The temperature of the whole wire becomes lower than the temperature at the contact point between the heating wire and the needle terminal of the conductive wire, and the heat supply effect is reduced.

  As can be seen from the above, the inventor has solved various problems in the manufacture and use of prior art garment electric heating devices, and with the help of manufacturing and design experience and knowledge in related fields, The present invention was devised by narrowing down.

  First, FIG. 1 and FIG. 2 will be referred to. As shown in FIGS. 1 and 2, the heating piece structure sewn on the garment according to one embodiment of the present invention is composed of at least a shielding layer 1 and a heating unit 2.

  The shielding layer 1 includes an inner layer body 11 and an outer layer body 12. A sandwich layer 13 is formed between the inner layer body 11 and the outer layer body 12. A waterproof film 14 having a high melting point is formed on one surface of the sandwich layer 13, and the waterproof film 14 is made of polyurethane. The inner layer body 11 is thinner than the outer layer body 12.

  Please refer to FIG. As shown in FIG. 3, the heat generating unit 2 is disposed in the sandwich layer 13 of the shielding layer 1 and includes a high resistance wire 21 and a conductive wire 22 connected to the high resistance wire 21. The high resistance wire 21 may be made of a metal fiber yarn or a carbon fiber yarn, and the electric wire 221 at one end for connecting the conductive wire 22 and the high resistance wire 21 is divided into two or three forks and wound around the high resistance wire 21 sequentially. Thereby, the area where the electric wire 221 of the conducting wire 22 and the high resistance wire 21 are brought into contact is increased. A sleeve 23 having an elastic soft heat shrinkability is externally fitted to the contact point where the conductive wire 22 and the high resistance wire 21 are in contact with each other, and the contact point between the conductive wire 22 and the high resistance wire 21 is formed by the sleeve 23 having the heat shrinkability. The other end of the conductive wire 22 is extended to the outside of the shielding layer 1 to be electrically connected to the controller and the power supply unit.

  Please refer to FIG. 2 and FIG. As shown in FIGS. 2 and 4, when actually assembling, first, the high resistance wire 21 connected to the conductive wire 22 is arranged on the waterproof film 14 of the inner layer body 11 of the shielding layer 1, and then waterproofed. The surface of the outer layer body 12 having the film 14 covers the high resistance line 21 and is bonded to the outer layer body 12, and the high resistance line 21 is placed in the sandwich layer 13 formed between the inner layer body 11 and the outer layer body 12. After the arrangement, high temperature and high pressure are applied to the outside of the inner layer body 11 and the outer layer body 12 of the shielding layer 1, and the waterproof film 14 having a high melting point provided between the inner layer body 11 and the outer layer body 12 is melted by heat ( 5), the high resistance wire 21 in the sandwich layer 13 formed between the inner layer body 11 and the outer layer body 12 is bonded to the inner layer body 11 and the outer layer body 12 of the shielding layer 1 after melting. The sandwiched layer 13 of the shielding layer 1 after the waterproof membrane 14 is cooled and the waterproof membrane 14 is cooled. It is stably fixed to. As a result, the waterproof film 14 protects the clothes to be washed with water, prevents water from penetrating the contact point between the high resistance wire 21 and the conductive wire 22 provided in the sandwich layer 13, and the conductive wire 22 and the high resistance wire. In the process of protecting the contact between the conductive wire 22 and the high resistance wire 21 and washing the clothes and squeezing them using the sleeve 23 having heat shrinkability that is fitted on the outside of the contact with the conductive material 21, The contact with the resistance wire 21 is prevented from being damaged due to force. Subsequently, the shielding layer 1 is positioned between the high resistance wires 21 and the separation lines 15 are sewn to separate the high resistance wires 21, so that the high resistance wires 21 and the high resistance wires 21 come into contact with each other, thereby providing a heat supply effect. Deterioration is prevented, and the periphery of the inner layer body 11 and the outer layer body 12 is stitched together to assemble the shielding layer 1 and the heat generating unit 2.

  The assembled shielding layer 1 and heat generating unit 2 are sewn to clothing such as clothing, gloves, a hat, and shoes. When it is necessary to prevent the cold, the user turns on the power supply unit by the controller after wearing the clothes having the heat retaining function of the present embodiment, and heats the high resistance wire 21 connected to the conducting wire 22, thereby the high resistance wire 21. When heat is generated by heat conduction, thermal energy is released from the high resistance wire 21 and is transmitted to the user's body through the shielding layer 1. In the present embodiment, since the inner layer body 11 of the shielding layer 1 is thinner than the outer layer body 12, the heat energy released from the high resistance wire 21 is discharged to the outside from the inner layer body 11, and most of the heat energy is transferred to the user's body. Used to warm up. Since the heat generating unit 2 provided on the outside has a large thickness, it can obtain a heat insulating and heat retaining effect and reduce energy consumption.

  One end where the conductive wire 22 and the high resistance wire 21 are connected is divided into a plurality of crotch electric wires 221 and wound on the high resistance wire 21 to greatly increase the contact area with the high resistance wire 21. The current resistance generated at the location where the conductive wire 22 is connected is reduced as much as possible to prevent the occurrence of hot spots, and the efficiency of the thermal energy supplied from the high resistance wire 21 through the current to the high resistance wire 21 is increased. .

As can be seen from the above, the heating piece structure sewn on the garment of the present invention has the following advantages (1) to (6).
(1) A waterproof film having a high melting point is formed between the inner layer body and the outer layer body of the shielding layer, and a sandwich layer is formed in combination with one surface of the waterproof film to place the high resistance wire of the heat generating unit. Depending on the configuration, when actually combining, high resistance wires are arranged in the sandwich layer, high temperature and high pressure are applied to the inner layer body and the outer layer body, the waterproof film of the inner layer body and the outer layer body are melted and bonded, Combine the shielding layer and the heating unit.
(2) The sandwich layer provided between the inner layer body and the outer layer body of the shielding layer has a waterproof piece. Since this waterproof piece has a very high melting point, even if the high resistance wire generates heat, it does not melt by heat. Therefore, since the high resistance wire is stably combined with the shielding layer, water can be prevented from entering the high resistance wire.
(3) Since one end where the lead wire of the heat generating unit and the high resistance wire are connected is divided into a plurality of crotches and the high resistance wire is wound, the contact area between the high resistance wire and the electric wire of the lead wire is greatly increased. Effectively reduce the resistance generated at the connection point and flow the current smoothly through the high resistance wire to enhance the heat supply effect of the heat generating unit.
(4) Since the inner layer body of the shielding layer is thinner than the outer layer body, when the heat generating unit provided in the sandwich layer formed between the inner layer body and the outer layer body operates to generate heat, the heat energy generated from the heat generating unit Can be quickly transferred from the thin inner layer to provide the user with most of the thermal energy.
(5) Sewing separation lines between the high resistance lines of the shielding layer to ensure separation of the high resistance lines prevents the high resistance lines from hitting each other in the process of use and cleaning, Ensure safety of use.
(6) The contact between the high resistance wire and the conductive wire is externally fitted with a heat-shrinkable sleeve to protect the contact between the conductive wire and the high resistance wire. Prevents contact with wires from being damaged by force.

  The preferred embodiments of the present invention have been disclosed as described above so that those skilled in the art can understand them, but these do not limit the present invention in any way. Various changes and modifications can be made without departing from the spirit and scope of the present invention. Accordingly, the scope of the utility model registration claim of the present invention should be broadly interpreted including such changes and modifications.
