Description

Fever vest {HEATING VEST}

The present invention relates to a heating vest. More particularly, the present invention relates to a heating vest using a heating body obtained by weaving carbon fibers and hemp fibers.

Fever vests are used in a variety of places, such as outdoor and cold environments that require heat. As the heat source used for the heating vest, heating wires such as nichrome and copper are used. However, if a heating wire such as nichrome and copper is used, a short circuit may cause a fire.

In order to reduce the risk of fire, a heating vest using urethane as an insulating member may be used. However, urethane materials have low flexibility, so heating lines may break or short circuits may occur. Moreover, the heating vest is used by highly active workers, and there is a high probability that the heating line will be disconnected or short-circuited due to high movement. In addition, there is a high possibility that a short-circuit occurs due to the weakness of the heating line due to moisture.

The present invention provides a flexible heating vest using a heating body woven carbon fiber and hemp fiber.

The heating vest according to an embodiment of the present invention includes: i) a vest body formed with at least one housing portion, and ii) a flexible heating pad housed in the housing portions. The heating pad comprises: i) a pair of metal electrodes connected to an external power source and supplied with power and extending in a first direction; ii) a pair of metal electrodes extending long in a second direction intersecting the first direction, Iii) a plurality of single warp yarns stretched in a first direction and interwoven with the weft yarns and woven together, and iv) a plurality of conductive composite weft yarns extending from the plurality of conductive composite weft yarns, And a cover member surrounding the single warp yarns. One or more warp yarns of the single warp yarns comprise hemp and the hemp comprises one or more fibers selected from the group consisting of flax, ramie, hemp and jute.

The one or more receptacles include a plurality of receptacles, the receptacles being spaced apart from one another, the receptacles including an inlet formed in the periphery thereof and adapted to insert the heating pad through the inlet. Iii) a second front portion connected to a second side spaced apart from a first side of the rear portion; and iv) a second front portion connected to the first front portion and the second front portion, And a fastening portion for attaching and detaching the second front portion. The rear portion, the first front portion and the second front portion may each have receiving portions, and the size of the receiving portion of the rear portion may be larger than the size of the receiving portion of the first front portion and the receiving portion of the second front portion. The inlet port of the receiving portion of the first front surface portion and the inlet port of the receiving portion of the second front surface portion may be adjacent to the coupling portion and open and close toward the coupling portion, respectively.

The inlet of the receiving portion on the rear side is adjacent to the neck on the rear side and can be applied to open and close toward the neck. The heating vest according to an embodiment of the present invention may further include one or more batteries installed on one or more sides selected from the group consisting of the first side and the second side to supply electric power. The at least one battery includes a plurality of batteries, the plurality of batteries are respectively installed at the first side and the second side, and the heating pad housed in the receiving portion at the rear portion may be connected to each of the plurality of batteries.

It is possible to provide a heating vest which is free from trouble and can be continuously used even if it is used by a highly active worker. Therefore, even if the worker uses it in a harsh environment, the worker can be made warm and the work efficiency can be improved. In addition, the heating element can be easily detached, and the position of the power source connected to the heating element can be placed at a desired position of the user in the up, down, left and right directions, which is convenient to use.

The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Fig. 1 schematically shows a heating vest 100 according to an embodiment of the present invention. The structure of the heating vest 100 of FIG. 1 is merely for illustrating the present invention, and the present invention is not limited thereto. Therefore, the structure of the heating vest 100 can be modified in other forms.

1, the heating vest 100 includes a vest body 11 and heating pads 14, 24, and 34. As shown in Fig. In addition, the heating vest 100 may further include other components as needed.

The vest body 11 includes a rear portion 10, a first front portion 20, and a second front portion 30. The rear portion 10 is connected to the first front portion 20 and the second front portion 30, respectively. The fastening part 40 attaches and detaches the first front part 20 and the second front part 30. Although the fastening portion 40 is shown in Fig. 1 as a zipper, it may be formed using a button or the like.

As shown by the dotted arrows in FIG. 1, the inner surfaces of the rear portion 10, the first front portion 20, and the second front portion 30 are formed with receiving spaces 12, 22, and 32 spaced apart from each other . The heat receiving pads 14, 24 and 34 are housed in the respective housings 12, 22 and 32, respectively. Therefore, even when the wearer of the heating vest 100 is cold, the body temperature can be maintained and the working efficiency can be improved. Hereinafter, the structure of the heating vest 100 of FIG. 1 will be described in more detail with reference to FIG.

Fig. 2 schematically shows a state in which the heating vest 100 of Fig. 1 is opened. The structure of the heating vest 100 of FIG. 2 is merely for illustrating the present invention, and the present invention is not limited thereto. Therefore, the structure of the heating vest 100 of FIG. 2 can be modified to other forms.

2, the rear portion 10 includes a neck portion 103, a first side portion 105, and a second side portion 107. As shown in Fig. The first side portion 105 and the second side portion 107 are spaced apart from each other. The first front portion 20 is connected to the rear portion 10 through the first side portion 105. Also, the second front portion 30 is connected to the rear portion 10 through the second side portion 107. Accordingly, the first front portion 20, the rear portion 10, and the second front portion 30 are connected in order when the heating vest 100 is opened.

Since the heating pads 14, 24, and 34 are manufactured in a flexible manner, there is little possibility of failure such as disconnection even when the heating vest 100 is put in or taken out in a harsh environment. The heating pads 14, 24 and 34 are accommodated in the receiving portions 12, 22 and 32 formed in the rear portion 10, the first front portion 20 and the second front portion 30, respectively. The heat generating pads 14, 24 and 34 housed in the housings 12, 22 and 32 are brought into close contact with the wearer's body of the heating vest 100, thereby providing heat necessary for maintaining the body temperature.

The size of the receiving portion 12 formed on the inner surface 101 of the rear portion 10 is larger than the size of the receiving portions 12 formed on the inner surface 201 of the first front portion 20 and the inner surface 301 of the second front portion 30 (22, 32). Therefore, since the area covered by the rear portion 10 is the entire back of the human body, it is larger than the first front portion 20 and the second front portion 30, Can be made.

The batteries 50 supply power to the heating pads 14, 24, and 34 to heat the heating pads 14, 24, and 34. Although the batteries 50 are shown as being installed on both the first side 105 and the second side 107 in Fig. 2, they may be installed in any one of them as needed. The batteries 50 may be installed on the first side face 105 and the second side face 107 to minimize the contact area of the heating vest 100 with the wearer so that inconvenience during wearing can be minimized. The batteries 50 can be recharged when they are discharged using a secondary battery or the like. On the other hand, since the heating pad 14 covers a large area of the back region, the consumed power may be large. Therefore, all of the batteries 50 located on the left and right of the heating pad 14 are connected to receive power for heating a large area. When the line connecting the heating pads 14, 24, and 34 to the batteries 50 is exposed to the outside, problems may occur due to contact with external objects in the work environment of the wearer 100 . Therefore, as shown by a dotted line in FIG. 2, internal passages can be formed in the inner surfaces 101, 201, and 301 to prevent the wiring from being exposed to the outside. Since the heating pads 14, 24, 34 and the batteries 50 are connected through the small terminals (not shown), detachment is very convenient.

On the other hand, as shown in Fig. 2, the inlets 221 and 321 are formed at the edges of the housings 22 and 32, respectively. The inlet ports 221 and 321 may be opened to accommodate the heating pads 24 and 34. The inlets 221 and 321 face the left and right outer sides of the heating vest 100 so as to be opened and closed toward mutually adjacent coupling portions 40, respectively. Therefore, it is convenient to insert and remove the heating pads 24 and 34. The inlet 121 formed at the upper edge of the storage portion 12 is adjacent to the neck portion 103 and is opened and closed toward the neck portion 103. [ Therefore, the heat generating pad 14 can be inserted and removed through the inlet 121. Since the inlet 121 is formed on the upper edge of the receiving portion 12, when the heating pad 14 is attached and detached, the contact between the heating pad 14 and the left and right objects is reduced and the heating pad 14 is not dropped down. Therefore, the heat generating pad 14 can be firmly and conveniently stored. The inlets 121, 221, and 321 may be formed of zippers or buttons.

Fig. 3 schematically shows a state in which the heating vest 100 is connected to the power supply device 60 and the temperature control device 70. Fig. Hereinafter, the heating vest 100 is connected to the power source unit 60 and the temperature control unit 70 to explain the heat generation of the heating pads 14, 24, and 34, will be described in detail with reference to FIG.

3, the metal electrode 601 of the heating pads 14, 24, and 34 is connected to the power supply device 60 and the temperature control device 70 through the power supply line 401. Since the temperature sensors 501 are installed in the heating pads 14, 24 and 34, the temperature sensors 501 sense the temperatures of the heating pads 14, 24 and 34 and transmit them to the temperature control device 70. The temperature of the measured heating pad 14, 24, 34 is displayed on the temperature control device 70. The temperature control device 70 allows the user to easily use the heating vest 100 (shown in Fig. 2), including a timer function and a heat reservation function. On the other hand, the power source line 401 can be housed in a device accommodation space (not shown) formed in an inner skin (not shown).

The power supply device 60 supplies electric power required for generating heat of the heat generating pads 14, 24, and 34. The power supply unit 60 can be plugged into an outlet or the like of a house or operated by a portable battery or the like. In this case, the heating vest 100 can also be used outdoors. Hereinafter, the structure of the heat generating pads 14, 24, and 34 of FIG. 3 will be described in more detail with reference to FIG.

Fig. 4 partially depicts the heating pads 14, 24, 34 of Fig. 3 and enlarged view of the conductive composite wefts 303 in the enlargement of Fig. The structure of the heating pads 14, 24, and 34 in FIG. 4 is merely for illustrating the present invention, and the present invention is not limited thereto. Therefore, the structure of the heating pads 14, 24, and 34 can be modified in other forms.

4, the heating pads 14, 24, and 34 include a pair of metal electrodes 601, wefts 303, warp yarns 305, and a bonding portion 309. As shown in Fig. The metal electrode 601 is electrically connected to the power supply unit 60 (shown in FIG. 3) to apply electric power to the wefts 303.

The pair of metal electrodes 601 are elongated in the y-axis direction. The pair of metal electrodes 601 may be made of a material such as copper or nickel. The metal electrodes 601 may be formed in the form of a thin film or a rod.

The weft yarns 303 are elongated in the x-axis direction which is a direction intersecting with the direction in which the metal electrode 601 extends. 4, the weft yarns 303 include a core 3031 including fibers and a carbon layer 3033. [ Cotton yarn or the like can be used as the material for the fiber. The carbon layer 3033 is coated on the outer surface of the core 3031. In this case, the thickness of the carbon layer 3033 may be 0.5 mm to 0.6 mm. More preferably, it may be 0.56 mm to 0.58 mm. The carbon layer 3033 can be produced by adding conductive carbon to a thermosetting resin and then extruding it. In this case, the carbon layer 3033 can form a layered lattice in which a hexagonal ring shape of carbon is continuously connected. The weft yarns 303 have a conductivity because they include a carbon layer 3033 on their surfaces. The weft yarns 303 have a composite structure of the carbon layer 3033 and fibers.

Weft yarns 303 are formed between a pair of metal electrodes 601 to interconnect metal electrodes 301. That is, a power source applied to the metal electrodes 601 is supplied to the carbon layer 3033 so that the weft yarns 303 generate heat. The carbon layer 3033 is safe because it has a low risk of fire when compared with a copper wire used as a conventional heating element. Further, since the carbon layer 3033 is strong against moisture and excellent in impact resistance, it is suitable for a heating vest 100 for outdoor use for camping or the like. The carbon layer 3033 can increase the strength and flexibility of the heat generating pads 14, 24 and 34 by imparting a certain degree of elasticity to the weft 303.

The warp yarns 305 are elongated in the y-axis direction which intersects the extending direction of the weft yarns 303 and are interwoven with the weft yarns 303 and woven. The heating pads 14, 24 and 34 are formed by an Oxford weaving method in which the weft yarns 303 and the warp yarns 305 are crossed in two strands respectively or the weft yarns 303 and the treads 305, Can be produced using a weaving method. In this case, since the strength of the heat generating pads 14, 24, and 34 becomes large, it can withstand a strong external force. On the other hand, the heating pads 14, 24, and 34 may include a cover member (not shown). The cover member surrounds the wefts of the weft yarns 303 and the warp yarns 305 and improves the waterproof effect and the water repellent effect through the silicone coating or the like. The warp yarns 305 are made of flax, ramie, hemp or jute. The warp yarns 305 thus have a single structure of one kind or of mutually similar yarns.

If carbon yarn containing carbon layer and general yarn are used for weaving, there is a difference in elastic modulus between carbon yarn and yarn. In this case, the weaving is interrupted, and the weaving body is not flat. Therefore, this phenomenon can be prevented by using hemp. That is, the average resilience percentage of the warp yarns 305 is used to keep the weaving body flat. Here, the average elastic recovery rate of the yarn may be 55% to 65%. If the average elastic recovery rate of the yarn is too large or small, a difference in elastic modulus between the weft yarns 303 and the warp yarns 305 may occur, causing the weft yarns to crawl. Therefore, the average elastic recovery rate of the carbon layer 3033 of the wefts 303 is adjusted to be similar to the average elasticity recovery rate using the above-described average elastic recovery ratio. That is, the difference between the average elastic recovery rate of the warp yarns 303 and the average elastic recovery rate of the warp yarns 305 is adjusted to 10% or less. As a result, since the heating pads 14, 24, and 34 are always kept in a flat state without crying, there is no problem in durability even if the heating pads 14, 24, and 34 are folded several times. More preferably, the difference between the average elastic recovery rate of the warp yarns 303 and the average elastic recovery rate of the warp yarns 305 can be adjusted to 5% or less.

As shown in FIG. 4, the warp yarns 305 are spaced apart from each other, and the distance d1 between the warp yarns 305 may be 1 cm to 1.5 cm. If the spacing of the warp yarns 305 is too small or too large, it is difficult to control the temperature of the heating pads 14, 24, 34. Therefore, it is preferable to adjust the separation distance d1 to the above-mentioned range. Since the warp yarns 305 containing warp yarns have small chargeability, static electricity hardly occurs. Therefore, when electric power is applied to the heat-generating pads 14, 24, and 34, arc generation due to static electricity can be prevented in advance. In addition, the warp yarns 305 include ridges and thus have acid resistance, alkali resistance and bacterial resistance. Therefore, it is preferable for use in the heating vest 100 used mainly in outdoor such as camping.

The bonding portion 309 connects the wefts 303 and the pair of metal electrodes 601 firmly. The bonding portion 309 can be manufactured by mixing a waterproofing agent and a urethane solution or the like with a conductive material such as carbon. In this case, the weight ratio of the waterproofing agent, the urethane solution and the carbon can be set to 500: 10: 1. The stirring time can be set to about 4 hours.

Hereinafter, the present invention will be described in more detail with reference to experimental examples. These experimental examples are only for illustrating the present invention. The present invention is not limited thereto.

Bending test of heat pad weaving body

Experimental Example 1

A weft yarn and a warp yarn having the same structure as in Fig. 3 were woven to prepare a heat generating pad. The heating pad used here was used for inserting into a heating vest. The weft was prepared by coating a 0.46 mm thick carbon layer on the outer surface of the cotton core. The warp yarns were produced using various kinds of yarns. The average elastic recovery rate of the manufactured weft was measured. The heat pad was manufactured by weft and warp, and then placed in a desiccator. The temperature and humidity of the desiccator were set at 20 ± 2 ° C and 65 ± 2%, respectively. The heating pad was maintained for 5 seconds according to the KES-FB system and then removed. The surface of the heating pad was observed after repeating this process 10 times. The remaining detailed experimental procedures can be easily understood by those skilled in the art, so that detailed description thereof will be omitted.

Experimental Example 2

A 0.48 mm thick carbon layer was coated on the outer surface of the cotton yarn. The remaining experimental procedure was the same as Experimental Example 1 described above.

Experimental Example 3

A 0.50 mm thick carbon layer was coated on the outer surface of the cotton yarn. The remaining experimental procedure was the same as Experimental Example 1 described above.

Experimental Example 4

A 0.52 mm thick carbon layer was coated on the outer surface of the cotton yarn. The remaining experimental procedure was the same as Experimental Example 1 described above.

Experimental Example 5

A 0.54 mm thick carbon layer was coated on the outer surface of the cotton yarn. The remaining experimental procedure was the same as Experimental Example 1 described above.

Experimental Example 6

A 0.56 mm thick carbon layer was coated on the outer surface of the cotton yarn. The remaining experimental procedure was the same as Experimental Example 1 described above.

Experimental Example 7

A 0.58 mm thick carbon layer was coated on the outer surface of the cotton yarn. The remaining experimental procedure was the same as Experimental Example 1 described above.

Experimental Example 8

A 0.60 mm thick carbon layer was coated on the outer surface of the cotton yarn. The remaining experimental procedure was the same as Experimental Example 1 described above.

Experimental Example 9

A 0.62 mm thick carbon layer was coated on the outer surface of the cotton yarn. The remaining experimental procedure was the same as Experimental Example 1 described above.

Experimental Example 10

A 0.64 mm thick carbon layer was coated on the outer surface of the cotton yarn. The remaining experimental procedure was the same as Experimental Example 1 described above.

Bending test result of heat pad weaving body

The difference in the average elastic recovery rates of the weft yarns and the warp yarns of the heat generating pads manufactured according to Experimental Examples 1 to 10 was investigated, and the calorific value and bending surface characteristics were examined.

As shown in Table 1, the smaller the thickness of the carbon layer, the smaller the calorific value. In Experimental Example 1 and Experimental Example 2, a surface phenomenon occurred on the surface of the heating pad and the bending surface characteristics were not good. In Experimental Examples 9 and 10, the heating pad was curled and the bending surface characteristics were not good. On the other hand, when the difference between the thickness of the carbon layer and the average elastic recovery rate was appropriately adjusted as in Experimental Example 6 and Experimental Example 7, a heating pad having an appropriate calorific value and bending surface characteristics could be manufactured.
