Description

Heated gloves with built-in heating pack

[0001] The present invention relates to a heated glove with a built-in heating pack. More specifically, it relates to a heated glove with a built-in heating pack having a structure that ensures free movement of the fingers while maintaining a constant temperature of the part in contact with the joint to alleviate finger joint pain.

[0002] Joint pain can be caused by degenerative arthritis, rheumatoid arthritis, finger muscle fatigue, or circulatory disorders. Heat therapy is frequently used to alleviate these symptoms. Heat therapy is effective in reducing pain by promoting blood circulation and relaxing muscles. However, existing heat therapy devices have the disadvantage of being too large or lacking portability, making them unsuitable for continuous use in daily life.

[0003] Conventional heated gloves had the problem of hindering finger flexibility. There was also the issue of discomfort caused by overheating when worn for a long time. Some products may experience problems where heating elements are not evenly distributed across the palms and fingers, resulting in only specific areas being heated. Furthermore, the lack of a temperature control function poses a risk of overheating or low-temperature burns.

[0004] If sufficient flexibility is not provided to the finger joints, it may be difficult to move the hands while wearing gloves. Accordingly, there is a need for heated gloves that allow for free movement of the fingers while maintaining a constant temperature. The present invention aims to solve these problems and provide heated gloves that can maximize the convenience of the wearer.

[0005] The objective of the present invention is to provide a heated glove with a built-in heating pack to solve the aforementioned problems.

[0006] The technical problems to be solved in the embodiments are not limited to those mentioned above, and other unmentioned technical problems may be considered by those skilled in the art from the various embodiments described below.

[0007] A heating glove with a built-in heating pack according to one embodiment of the present invention may include: a body comprising a plurality of finger portions into which each of a user's fingers can be inserted; one or more storage portions formed in at least a portion of the finger portions; and one or more heating elements disposed in each of the one or more storage portions and generating heat by reacting with air or moisture.

[0008] The heating element may include at least one of an iron powder-based heating element, a calcium oxide-based heating element, a magnesium-based heating element, or a sodium acetate-based heating element.

[0009] The above one or more storage portions may each be disposed in the finger portion area corresponding to the joint portion of the finger when the user's finger is inserted into the finger portion.

[0010] The above one or more storage portions may include a first storage portion corresponding to the fingernail portion of the finger when the finger is inserted into the finger portion, a second storage portion corresponding to the distal interphalangeal joint of the finger, a third storage portion corresponding to the proximal interphalangeal joint of the finger, and a fourth storage portion corresponding to the metacarpophalangeal joint of the finger.

[0011] At least one of the above one or more storage compartments may include two or more storage compartments that are physically separated from each other.

[0012] A heating glove according to one embodiment of the present invention can maintain a constant temperature without an external power source and provide an effect of relieving joint pain. Despite having a built-in heating pack, it offers flexibility to the finger joints, providing the advantage of not causing discomfort even when worn by the user for a long time. Multiple heating elements are arranged to provide a customized heating effect for users of various finger lengths, thereby enabling optimized heating for individual finger joints. In particular, since the storage compartments corresponding to the finger joints are composed of multiple physically separated compartments, the storage compartments and heating elements can move freely according to the movement of the finger even when the user bends their fingers, thereby increasing the freedom of finger movement. Through this structure, users with joint pain can easily apply heat therapy during their daily lives, thereby maximizing portability and convenience.

[0017] The following embodiments are combinations of the components and features of the embodiments in a predetermined form. Each component or feature may be considered optional unless otherwise explicitly stated. Each component or feature may be implemented in a form not combined with other components or features. Various embodiments may be constructed by combining some components and features. The order of operations described in various embodiments may be changed.

[0018] In the description of the drawings, procedures or steps that could obscure the essence of the various embodiments were not described. Procedures or steps that are understandable to a person skilled in the art were also not described.

[0019] Throughout the specification, when a part is described as "comprising" or "including" a component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. Terms such as "...part," "...unit," and "module" as used in the specification refer to a unit that performs at least one function or operation. This may be implemented in hardware, software, or a combination of hardware and software.

[0020] Hereinafter, embodiments according to various examples will be described in detail with reference to the accompanying drawings. The detailed description disclosed below, together with the accompanying drawings, is intended to describe exemplary embodiments of various examples. It is not intended to represent the only embodiment.

[0021] Specific terms used in various embodiments are provided to aid in understanding the various embodiments. The use of these specific terms may be modified in other forms within the scope of the technical spirit of the various embodiments.

[0022] FIG. 1 is a perspective view showing a heating glove (100) according to one embodiment of the present invention from one side. FIG. 2 is a perspective view showing a heating glove (100) according to one embodiment of the present invention from another side.

[0023] Referring to FIGS. 1 and 2, a heating glove (100) according to one embodiment of the present invention may have a structure including a plurality of finger portions (130) into which each of the user's five fingers can be inserted, similar to a conventional glove. It may have a body (150) in which the back surface of the hand and the palm surface are integrated. The heating glove (100) of the present invention may not differ significantly in its overall shape compared to a conventional glove.

[0024] The body (150) may be a structure that encloses the entire hand of the user. The body (150) may include a palm surface and a back surface of the hand. A plurality of finger portions (130) may be connected to the end portion of the body (150).

[0025] The finger portion (130) may be a tube-shaped structure into which each of the user's fingers can be individually inserted. Generally, five finger portions (130) may be formed. Each finger portion (130) may correspond to the thumb, index finger, middle finger, ring finger, and little finger.

[0026] A heated glove (100) according to one embodiment of the present invention may have a flexible structure to allow the fingers to move freely. The body (150) of the heated glove (100) may be formed from at least one material selected from neoprene, spandex, polyester, or natural leather, with consideration for durability and thermal insulation.

[0027] Neoprene is a type of synthetic rubber that can possess excellent elasticity and durability. It is water-resistant and offers superior thermal insulation, which can enhance the thermal performance of gloves. Spandex is a polyurethane-based synthetic fiber that can have very high elasticity. Spandex naturally responds to the movement of the fingers, improving comfort.

[0028] Polyester can be a lightweight and durable synthetic fiber. Due to its fast drying speed and resistance to wrinkles, polyester can maintain its shape even during prolonged wear. Natural leather is a material made from processed animal skin and can offer excellent breathability and durability. When worn, natural leather adheres softly to the skin, providing comfort.

[0029] In one embodiment, the body (150) of the heating glove (100) may be made by mixing neoprene and spandex. In this case, elasticity and thermal insulation can be secured simultaneously. In another embodiment, the body (150) of the heating glove (100) may be made of polyester as the main material, but spandex may be additionally applied to the finger joint area. In this case, flexible movement of the joint can be ensured.

[0030] A heating glove (100) according to one embodiment of the present invention may be manufactured in a shape that can closely fit the shape of the wearer's hand. In the heating glove (100) according to one embodiment of the present invention, a highly elastic material may be used in the finger joint area so that the fingers can move freely. The glove may be designed so that its shape naturally deforms when the fingers are bent.

[0031] A heating glove (100) according to one embodiment of the present invention may include one or more storage portions each housing one or more heating elements.

[0032] The storage portion may be formed in at least a part of the finger portion (130). The storage portion may be a pocket structure formed inside or outside the body (150). The storage portion may be formed of a flexible material so as to stably secure the heating element without hindering the movement of the finger.

[0033] In one embodiment, the storage portion may be formed of a non-woven fabric material. Oxygen can be introduced through the fine pores of the non-woven fabric to promote the chemical reaction of the heating element. In another embodiment, the storage portion may be formed of a mesh fabric. The mesh fabric has excellent breathability, which can facilitate the supply of air necessary for the reaction of the heating element.

[0034] Figure 3 is an enlarged view of the finger portion of the heating glove (100) of Figure 1.

[0035] Referring to FIG. 3, one or more storage portions may be placed on the finger portion (130).

[0036] One or more heating elements may be placed in each of one or more storage compartments. One or more heating elements may be placed in each of one or more storage compartments.

[0037] One or more heating elements may have a temperature within an operating temperature range when heating. The operating temperature range may be 38°C to 42°C. Preferably, it may have a temperature within an optimal temperature range of 39°C to 41°C.

[0038] Applying a temperature of 38°C or higher to the finger joints can promote blood circulation in the area. It may also help relax the muscles. When the optimal temperature of 39°C to 41°C is applied, it can relieve tension in the tissues surrounding the finger joints. This may result in a pain-reducing effect. However, if a temperature of 42°C or higher is sustained on the finger joints for an extended period, there is a risk of low-temperature burns. Therefore, it is advisable not to exceed 42°C.

[0039] Blood circulation is a process that supplies oxygen and nutrients to tissues and removes waste products. When the temperature of the joint area rises, blood vessels may dilate, increasing blood flow. Muscle relaxation is a phenomenon in which the tension in muscle fibers is released. Thermal stimulation can induce a relaxation response by stimulating nerve receptors within the muscles.

[0040] Low-temperature burns can be a phenomenon in which skin tissue is damaged for an extended period at relatively low temperatures of 40°C or higher. Unlike general burns, it is difficult to feel pain, making it difficult to recognize skin damage. Therefore, it may be safer to limit the maximum temperature of the heating element to 42°C or lower.

[0041] One or more heating elements may be configured to maintain an operating temperature range for at least 30 minutes. A duration of at least 30 minutes may be the minimum time required to provide a sufficient warming effect to the joint area. Generally, heat therapy may be effective if it lasts for about 30 minutes to 1 hour.

[0042] In one embodiment, one or more heating elements may be iron powder-based heating elements. The iron powder-based heating element may generate heat when iron (Fe) powder reacts with oxygen in the air and oxidizes. The reaction rate of the iron powder-based heating element can be controlled by mixing activated carbon, salt, and water.

[0043] The oxidation reaction of iron can be expressed by the chemical formula 4Fe + 3O2 → 2Fe2O3. This reaction is exothermic and can release thermal energy. Activated carbon is a carbon material with a porous structure and a large surface area, which can promote oxygen adsorption. Salt (NaCl) acts as an electrolyte and can increase the rate of the iron oxidation reaction.

[0044] Iron powder-based heating elements are inexpensive and can maintain a constant temperature. They have the characteristic of needing to be discarded after a single use. Iron powder-based heating elements can generally maintain a temperature of 50°C to 60°C. The duration can be 10 to 12 hours.

[0045] In another embodiment, one or more heating elements may be composed of calcium oxide (CaO)-based heating elements. The calcium oxide-based heating elements may utilize the principle that quicklime (CaO) reacts with water to become calcium hydroxide (Ca(OH)2), thereby generating heat.

[0046] The reaction between calcium oxide and water can be expressed by the chemical formula CaO + H2O → Ca(OH)2. This reaction is a strongly exothermic reaction that can rapidly release a large amount of heat. During the reaction, the temperature can rise to 120°C, but by controlling the amount appropriately, it can be maintained between 50°C and 60°C.

[0047] Calcium oxide-based heating elements can generate relatively strong heat. They are characterized by an immediate temperature rise effect. Calcium oxide-based heating elements can be widely used for heating combat rations.

[0048] In another embodiment, one or more heating elements may be made of magnesium (Mg)-based heating elements. The magnesium-based heating elements may be of a type in which magnesium powder reacts with moisture to generate heat.

[0049] The reaction between magnesium and water can be expressed by the chemical formula Mg + 2H2O → Mg(OH)2 + H2. This reaction can be exothermic while producing hydrogen gas. Magnesium-based heating elements can produce higher temperatures than iron powder-based heating elements.

[0050] Magnesium-based heating elements can be used in military and medical heating patches, etc. Magnesium-based heating elements can have a fast heating rate and a high heat output.

[0051] In another embodiment, one or more heating elements may be composed of sodium acetate-based heating elements. The sodium acetate-based heating elements may utilize the principle that heat is generated when sodium acetate crystallizes in a supercooled state.

[0052] Sodium acetate can be a salt with the chemical formula CH3COONa. As the liquid in a supercooled state crystallizes, it can release latent heat of phase change. During this process, the temperature can rise to about 54°C.

[0053] Sodium acetate-based heating elements can be reused. They can be used repeatedly by placing them in boiling water to re-liquefy them. They have the characteristic of being relatively stable in temperature.

[0054] In one embodiment, a sodium acetate-based heating element can initiate crystallization by pressing a metal disc. Physical impact of the metal disc can induce nucleation. In another embodiment, a sodium acetate-based heating element can be reactivated by immersing it in hot water at 100°C or higher for at least 10 minutes after use.

[0055] As described above, a material that may include one or more heating elements according to one embodiment of the present invention has been explained. The embodiments of the present invention are not limited thereto. In addition to the material described above, it should be interpreted that the heating glove (100) may include other heating elements capable of maintaining an operating temperature range for a certain period of time or longer.

[0056] Referring again to FIG. 3, the heating glove (100) of the present invention may include one or more storage compartments to provide a constant heating effect regardless of the user's finger length and joint position. One or more heating elements may be placed inside each storage compartment.

[0057] One or more storage portions may each be placed in a finger portion (130) area corresponding to a joint portion of the finger when the user's finger is inserted into the finger portion (130). The finger joint portion may be a joint portion where the finger bends. Each finger may have several joints, such as a proximal interphalangeal joint (PIP joint), a distal interphalangeal joint (DIP joint), and a metacarpophalangeal joint (MCP joint).

[0058] In one embodiment, one or more storage portions may include a first storage portion (131) corresponding to the fingernail portion of the finger when the finger is inserted into the finger portion (130), a second storage portion (133) corresponding to the distal interphalangeal joint of the finger, a third storage portion (135) corresponding to the proximal interphalangeal joint of the finger, and a fourth storage portion (137) corresponding to the metacarpophalangeal joint of the finger.

[0059] The first storage portion (131) may be positioned corresponding to the fingernail portion of the finger. The fingernail portion may be the distal portion of the finger. The first storage portion (131) may keep the fingertip warm.

[0060] The second storage portion (133) may be positioned corresponding to the distal interphalangeal joint (DIP joint) of the finger. The distal interphalangeal joint may be the joint between the first and second joints of the finger. It may be the joint closest to the fingertip.

[0061] The third storage portion (135) may be positioned corresponding to the proximal interphalangeal joint (PIP joint) of the finger. The proximal interphalangeal joint may be the joint between the second and third joints of the finger. It may be a joint located in the middle part of the finger.

[0062] The fourth storage portion (137) may be positioned corresponding to the metacarpophalangeal joint (MCP) of the finger. The metacarpophalangeal joint may be the joint at the part where the palm and the finger are connected. It may be a joint located at the base of the finger.

[0063] Generally, finger lengths may vary from user to user. If only a single heating element is placed, there is a possibility that heat will be effectively transferred only to a specific user. In order to solve this problem, the present invention configures a heating glove (100) by placing multiple storage compartments corresponding to various joint areas of the finger.

[0064] The arrangement of multiple storage compartments can be a structure capable of accommodating various finger lengths. Each storage compartment can correspond to a different joint position.

[0065] In addition, at least one of the one or more storage compartments may include two or more storage compartments that are physically separated from each other.

[0066] For example, referring to FIG. 3, the third storage portion (135) corresponding to the proximal interphalangeal joint of the finger may each include a third-1 storage portion (135-1), a third-2 storage portion (135-2), and a third-3 storage portion (135-3).

[0067] The 3-1 storage section (135-1), the 3-2 storage section (135-2), and the 3-3 storage section (135-3) can be physically separated from each other. Being physically separated means that each storage section forms an independent space and is not connected to each other. Each storage section can be formed as a separate pocket structure.

[0068] In this case, a third-1 heating element (230-1), a third-2 heating element (230-2), and a third-3 heating element (230-3) may be placed in each of the third-1 storage section (135-1), the third-2 storage section (135-2), and the third-3 storage section (135-3).

[0069] The 3-1 heating element (230-1) can be stored in the 3-1 storage section (135-1). The 3-2 heating element (230-2) can be stored in the 3-2 storage section (135-2). The 3-3 heating element (230-3) can be stored in the 3-3 storage section (135-3).

[0070] As described above, through a structure in which a storage portion corresponding to the finger joint area is composed of multiple physically separated storage portions, there is an advantage of allowing the user's finger movement to be free by allowing the storage portions and the heating elements placed in the storage portions to move freely in accordance with the bending of the finger, even when the user bends their finger.

[0071] When a finger is bent, wrinkles may form in the joint area as it folds. If the storage unit is formed as a single continuous structure, the storage unit and the heating element may become rigid when the finger is bent, thereby hindering movement. However, if the storage unit is composed of multiple physically separated units as in the present invention, each unit can move independently, allowing the finger's bending motion to be naturally accommodated.

[0072] In one embodiment, the 3-1 storage portion (135-1), the 3-2 storage portion (135-2), and the 3-3 storage portion (135-3) may be arranged in a line along the longitudinal direction of the finger portion (130). When the finger is bent, each storage portion may move while maintaining a distance from each other.

[0073] In another embodiment, the 3-1 storage portion (135-1), the 3-2 storage portion (135-2), and the 3-3 storage portion (135-3) may be arranged along the circumferential direction of the finger portion (130). They may be arranged in a manner that surrounds the finger joint 360 degrees.

[0074] In another embodiment, at least one of the first storage section (131), the second storage section (133), and the fourth storage section (137) may be composed of a plurality of storage sections that are physically separated from each other. All storage sections may have a structure in which they are physically separated.

[0075] The structure of the glove can be designed so that when the finger is bent, it naturally folds, allowing the heating element to be in closer contact with the joint area. If an elastic material is applied to the finger portion (130), the heating element can remain in maximum contact with the skin even while the finger is bent. This can maximize the heating effect.

[0076] The elastic material may be an elastic fiber such as spandex or Lycra. Such a material has an elongation rate of 400% or more and can flexibly respond to finger movements. In one embodiment, a blended fabric of 85% polyester and 15% spandex may be used for the finger joint area.

[0077] In this way, the heating glove (100) of the present invention can provide a customized heating effect to users with varying finger lengths. It may include one or more storage compartments and a plurality of heating elements. Through this, it can be configured to provide heating optimized for individual finger joint areas.

[0078] As described above, the heating glove (100) according to one embodiment of the present invention can maintain a constant temperature without an external power source and provide an effect of relieving joint pain. It can provide flexibility to the finger joints despite having a built-in heating pack. It has the advantage of not causing discomfort even when the user wears it for a long time. Through this structure, users with joint pain can easily apply heat therapy during their daily lives. Portability and convenience can be maximized.

[0079]

[0080] FIG. 4 is a drawing illustrating an exemplary heating glove (400) according to another embodiment of the present invention.

[0081] Referring to FIG. 4, the heating glove (400) may further include a temperature sensor (410), a power supply unit (420), and a heating control unit (430). One or more heating elements included in the heating glove (400) can maintain an operating temperature in an electric heating manner based on power supplied from the power supply unit (420).

[0082] An electric heating method can be a method of converting electrical energy into thermal energy. According to Joule's law, heat can be generated when current passes through a resistor. The amount of heat generated can be calculated as Q = I²Rt (Q: amount of heat, I: current, R: resistance, t: time).

[0083] In this case, one or more heating elements may be implemented in the form of at least one of a carbon nanotube (CNT) film, a graphene heating element, a nichrome wire, or a metal film heater. When power is supplied from an external source, it may operate by generating heat through resistance.

[0084] At least a portion of the temperature sensor (410) may be positioned to be in contact with a heating element. The temperature inside the glove can be detected in real time. It can perform the function of controlling the temperature so as not to exceed a set operating temperature (38°C to 42°C).

[0085] Real-time detection may mean measuring the temperature at intervals of 0.1 to 1 second. The temperature sensor (410) can convert an analog voltage signal into digital data and transmit it to the heat control unit (430).

[0086] In one embodiment, the temperature sensor (410) may be composed of a thermistor. The thermistor may be a semiconductor device whose resistance value changes with temperature. For the NTC (Negative Temperature Coefficient) type, the resistance may decrease as the temperature rises.

[0087] In another embodiment, the temperature sensor (410) may be configured as a Resistance Temperature Detector (RTD). The RTD may be a sensor using a metal resistor such as platinum or nickel. Accurate measurement may be possible as the temperature and resistance values ​​have a linear relationship.

[0088] In another embodiment, the temperature sensor (410) may be configured as a semiconductor temperature sensor. The semiconductor temperature sensor may utilize the voltage-temperature characteristics of a PN junction. It may be provided in the form of an IC such as an LM35, DS18B20, etc.

[0089] Temperature data detected by the sensor can be transmitted to the power supply unit (420) and the heat control unit (430). This allows the user to maintain a constant temperature inside the glove. This prevents the risk of overheating or low-temperature burns.

[0090] Overheating may occur when the temperature of the heating element exceeds 42°C. Low-temperature burns may occur when exposed to temperatures above 40°C for a long time. This can be prevented by feedback control of the temperature sensor (410) and the heating control unit (430).

[0091] The power supply unit (420) can serve to supply power to the heating element. It can operate on a battery basis. The power supply unit (420) may include at least one of a rechargeable lithium-ion battery, a disposable battery, or a USB power supply. This allows the user to continuously use the heating function for a desired amount of time.

[0092] Lithium-ion batteries can be rechargeable batteries with high energy density. They can be repeatedly charged and have a low self-discharge rate. Generally, they can have a nominal voltage of 3.7V.

[0093] Disposable batteries may include alkaline batteries, etc. They provide a voltage of 1.5V and can be used by connecting multiple units in series. USB power supplies can provide a standard voltage of 5V.

[0094] In one embodiment, the power supply (420) may be inserted inside the glove. A battery may be stored in a pocket on the wrist. In another embodiment, the power supply (420) may be placed as a detachable battery pack on the wrist. It may be easily replaced by being secured with a Velcro strap.

[0095] Smart power management features may be included for low power consumption. It may include a feature that automatically cuts off power if not used for a certain period of time. For example, it may switch to standby mode if there is no change in temperature for 10 minutes.

[0096] The heating control unit (430) can perform the function of precisely controlling the temperature of the heating element based on data transmitted from the temperature sensor (410) and the power supply unit (420). The heating control unit (430) can control the amount of heat generated using a Pulse Width Modulation (PWM) method or a voltage control method. It may include a multi-stage temperature setting function so that the user can directly control the temperature.

[0097] The PWM method can be a method of controlling average power by rapidly switching the power on and off. The amount of heat generated can be changed by adjusting the duty cycle. For example, a 50% duty cycle can be equivalent to supplying 50% of the power.

[0098] The voltage regulation method may be a method of directly changing the voltage supplied to the heating element. The voltage can be varied using a DC-DC converter. For example, the voltage can be adjusted from 3V to 5V.

[0099] The multi-stage temperature setting can be configured into three levels, such as low temperature (38°C), medium temperature (40°C), and high temperature (42°C). The user can select it via a button or switch. In one embodiment, a temperature control button may be placed on the wrist portion.

[0100] In one embodiment, one or more heating elements may be made of a carbon nanotube (CNT) film. The carbon nanotube film may be an ultrathin heating film composed of nanometer-sized carbon structures. It may be a method of generating heat using electrical resistance.

[0101] Carbon nanotubes can be cylindrical molecules in which carbon atoms are arranged in a hexagonal network structure. They can have a diameter of several nanometers and a length of several micrometers. They can possess excellent electrical and thermal conductivity.

[0102] Carbon nanotube films can be thin and flexible. When inserted inside a glove, they may not hinder the wearer's finger movements. Uniform heating is possible. The heating speed can be fast. They have the characteristic of maintaining a constant temperature even with low power consumption.

[0103] In another embodiment, one or more heating elements may be graphene heating elements. The graphene heating element may be a method of generating heat by electrical resistance using a single-layer or multi-layer graphene film.

[0104] Graphene can be a material in which carbon atoms are arranged in a two-dimensional planar structure. Its thickness can be a single atomic layer of 0.34 nm. It can have high electrical and thermal conductivity.

[0105] Graphene can have high thermal conductivity. It can allow heat to be distributed evenly inside the glove. It can provide a rapid heating rate. The graphene heating element can be thin and flexible. When placed on the finger portion (130), it has the characteristic of being usable without discomfort even when the wearer bends or extends their hand.

[0106] In another embodiment, one or more heating elements may be made of nichrome wire. The nichrome wire heating element may be composed of a nickel (Ni) and chromium (Cr) alloy wire. It may be a method in which heat is generated as the wire heats up when power is supplied.

[0107] Nichrome alloys can generally be composed of 80% nickel and 20% chromium. With a high resistivity of 1.0 x 10^(-6) Ω·m, it can have good heating efficiency. It has a high melting point of 1400°C, so it can be stable even at high temperatures.

[0108] Nichrome wire can generate stable heat even at relatively high temperatures. It features excellent durability, allowing for repeated use. When placed inside a glove in wire form, it can flexibly adapt to the curvature of the fingers.

[0109] In one embodiment, the nichrome wire may be placed on the finger portion (130) in a zigzag pattern. The joint area can be heated intensively. In another embodiment, the nichrome wire may be manufactured with a diameter of 0.1 mm to 0.3 mm. Flexibility and durability can be ensured simultaneously.

[0110] In another embodiment, one or more heating elements may be metal film heaters. The metal film heater may have a structure in which a thin metal layer generates heat through electrical resistance. It may be manufactured to be ultra-thin. When inserted inside a glove, it may not affect the wearing comfort. Uniform heating may be possible.

[0111] The metal film can be made of stainless steel, copper-nickel alloy, etc. It can be very thin with a thickness of 10 μm to 100 μm. It can be formed on a polyimide substrate by a deposition process.

[0112] Metal film heaters can generate heat quickly. They are characterized by high power efficiency. They can also be implemented by concentrating heat on specific areas.

[0113] As described above, a material that may include one or more heating elements according to one embodiment of the present invention has been explained. The embodiments of the present invention are not limited thereto. In addition to the material described above, it should be interpreted that the heating glove (400) may include other heating elements capable of maintaining an operating temperature range for a certain period of time or longer.

[0114] As described above, a heating glove (400) according to another embodiment of the present invention may further include a temperature sensor (410), a power supply unit (420), and a heating control unit (430). It can be reused multiple times. Due to the temperature maintenance function of the heating control unit (430), a constant temperature can be maintained even during long-term use. This can solve the problem of disposal after a single use that may occur when using a chemical heating element. By making the glove reusable, economic efficiency can be increased.

[0115] Although the embodiments have been described above with reference to the limited drawings, those skilled in the art can apply various technical modifications and variations based on the above. For example, appropriate results can be achieved even if the described techniques are performed in a different order than described, or if the components of the described system, structure, device, circuit, etc. are combined or assembled in a form different from described, or if they are replaced or substituted by other components or equivalents.

[0116] Therefore, other implementations, other embodiments, and equivalents to the claims also fall within the scope of the claims set forth below.
