Description

Cold Hot Pack

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates generally to a cold and warmable fomentation pack, and more particularly, to a cold and hot placeable fomentation pack which enables a more efficient and effective use of a Peltier element and a fluid member to cool or warm a foment area of a user's body, .

BACKGROUND ART Conventionally, a hot and warmable pack capable of selecting one of hot and cold foments for a necessary part after cooling or warming the fomentation pack using a microwave oven, boiling water, a refrigerator / freezer or the like is used there was.

As a method of using it, if you use a microwave oven during warming, use it for 4 ~ 5 minutes. If boiling water is used, it is used for 10 minutes. In addition, in the case of cold fomentation, it is put in the refrigerator room for about 2 to 3 hours and used in the freezer room for about 30 minutes.

However, in the conventional hot pack, it is impossible to use the whole pack of the hot pack only by either the hot pack or the hot pack due to the heating or cooling method described above, and it is impossible to use the pack as a hot pack. , A refrigerator / freezer, and the like.

In addition, as described above, a preparation time of at least 4 to 5 minutes is required for on-fomentation, and a preparation time of at least 30 minutes is required for even cold-fomentation.

In addition, in case of warming in boiling water for warming, if the warming pack is wrapped with a towel or the like and is not heated, the pot and the cover of the hotchamping pack are directly contacted to cause the product itself to be damaged. Min or left at a temperature of minus 15 ° C or less for a long time, the hot pack was cured hardly, so that the user could not closely adhere to the shape of the other hot pack parts or the like.

In addition, there is a problem in that the use of the hot pack is very inconvenient because moisture is generated on the outer pack when used, and there is a serious problem that the temperature of the hot pack can not always be maintained at a temperature suitable for the desired pack. In other words, when the hot pack of the hot pack which is taken out from the microwave oven, boiling water or freezing room is directly applied to the skin, there is a possibility that the hot or cold temperature may cause injury such as burn or frost on the skin. There is a problem that it is difficult to obtain sufficient fomenting effect.

Apart from this, there has been studied a technique of heating or cooling an object using a Peltier element using a Peltier effect. Peltier effect is a thermoelectric phenomenon that is opposite to the seebeck effect. It refers to the effect of heat absorption and release at the junction when different metals are bonded and voltage is applied. That is, a phenomenon that produces a difference in temperature from a voltage. Such a Peltier effect is one of the thermoelectric effects together with the Thomson effect. A Peltier element is also called a thermoelectric module, a Phelz element, or a thermoelectric module. When a direct current flows, an endotherm occurs on one side and a heat is generated on the other side (that is, heat is transferred from the endothermic surface to the heat- ). When the polarity of the current is reversed, the relationship is reversed, so that it is very suitable for precise temperature control. The performance of the Peltier element is expressed by the maximum heat absorbing amount (Q _max ), the maximum current (A _max ), and the maximum voltage (V _max ).

Here, when the applied voltage is increased, the amount of heat generation is increased and the cooling efficiency is lowered. Therefore, 50 to 60% of the maximum voltage is known as the optimum voltage.

Currently, Peltier devices are used in small heating / cooling systems as their applications. As an example, in the case of application to a cooling device, since it is easy to miniaturize the device and does not generate noise or vibration as compared with a cooling method using a reverse carnot cycle used in a domestic electric refrigerator or an air conditioner, , A small cold / hot-freezer installed in a vehicle or the like, a medical stimulation and cooling device, and the like.

Despite these advantages, however, there is a drawback that the cooling mechanism is poor in power efficiency and cooling efficiency because the amount of heat dissipated by the device itself is greater than the heat transferred. In other words, since the heat absorbed by the heat absorbing side and the power consumed heat are generated on the heat radiation side, it is difficult to dissipate the heat of the Peltier element itself, and thus it has not been widely used as a cooling means. In addition, unlike heat exchange with a heat pump or the like, "heat transfer" means that when the load is applied without performing sufficient heat radiation on the heat generation side, not only the cooling efficiency on the heat absorption side is significantly lowered, There is great concern.

In recent years, attention has been focused on the advantages of the Peltier element described above, that is, the fact that the Peltier element is easy to miniaturize and the temperature control is easy, and the Peltier element is used as an educt after various surgical treatments such as dissolving heat for body heat, beauty, There has been an effort to utilize it in a poultice apparatus for the purpose of treatment, physical therapy, and the like. Such efforts have appeared in products such as a helmet type that emit cold or warm air in contact with the head part (see FIG. 1 and Patent Document 1).

However, since the poultice device described in Patent Document 1 can not be brought into close contact with the skin, it is difficult to expect a uniform poultice effect, and the state of pushing the head portion into a narrow cave gives a great rejection feeling, Is too large in size to be installed in a dedicated facility so that it is virtually impossible to carry out the portable terminal. That is, the poultice device described in Patent Document 1 has not fully utilized the above-described advantages of the Peltier device in its constitution, and the effect thereof is not remarkable. Especially, since the structure that can be adhered to the application site is not taken, the effect of the fomentation is not much larger than expected.

<Composition of hot and cold warmable pack>

2 is a cross-sectional view schematically showing a cold / hot pack material 1 according to an embodiment of the present invention.

2, the cold / hot pack 1 includes a cold / hot pack member (hereinafter also referred to as a cover) 10 and a Peltier element 20 provided in the cover 10. As shown in FIG.

The cover 10 surrounds the Peltier element 20 and functions as a basic cover to prevent breakage of the inner member due to scratching from the outside or impact due to falling or the like, And at least one portion of the user's body that is in contact with the body fomenting region so as to smoothly transfer heat between the body portion and the body fomenting region. In the present embodiment, the cover 10 is in direct contact with the human body, and therefore, it is preferable that the cover 10 is made of a material such as a harmless resin when it touches the human body. As for the material of the resin used for the cover 10, any material may be used which is harmless to the human body and can seal a fluid type member of a gel type, which will be described later. For example, PVC, urethane or a mixture thereof, which is a thermoplastic resin, or a material containing a loess component, a herb component, and a char component may be used as a covering material of the hot and warm pad.

In the Peltier element used in the cold / hot pack of the present invention, when a DC voltage is applied to both ends of two metals in a state where two different metals are bonded with two contacts, the charge carriers (electrons and / or holes) The heat is transferred from one metal side to the other metal side while moving the underlying metal. Referring to FIG. 3, when a current flows counterclockwise, holes in the P-type semiconductor are generated at the fourth contact and move toward the second contact, and the electrons in the N-type semiconductor move in the opposite direction, that is, at the third contact Move toward the contact No. 1. Here, the holes / electrons serve to carry heat and as a result, the plates 3 and 4 are constantly cooled, and the plates 1 and 2 continue to heat up. Further, if the polarity of the applied voltage is reversed, the heat absorbing portion and the heat generating portion are exchanged with each other, and the heat flow is also reversed. The Peltier element that uses this effect is the Peltier element.

In an embodiment of the present invention, it is preferable that the thermally conductive member 70 is adjacent to at least one of the heat absorbing surface 50 and the heat dissipating surface 60 of the Peltier element 20. The material of the thermally conductive member 70 is not particularly limited, and any member made of a known material may be used as long as it is a member having a predetermined degree of strength while having high thermal conductivity. For example, the thermally conductive member may be made of a metallic material such as aluminum or copper.

It is also preferable that the thermally conductive member 70 has a surface area larger than the surface area of the heat absorbing surface 50 or the heat dissipating surface 60 of the Peltier element. That is, since the main purpose of providing the thermally conductive member 70 is for the good heat transfer between the heat absorbing surface 50 and / or the heat dissipating surface 60 of the Peltier element and a fluid member to be described later, Is preferably larger than the surface area of the heat absorbing surface 50 and / or the heat dissipating surface 60 of the Peltier element. A known technique can be used to form the heat conductive member 70 adjacent to the heat absorbing surface 50 or the heat dissipating surface 60 of the Peltier element 20. However, It is preferable to enhance the heat transfer performance by filling the gaps existing between the heat sink and the heat sink.

In addition, the thermally conductive member 70 may be composed of a single member. For example, the thermally conductive member 70 may be formed of a plurality of metal pieces connected in the same flexibility, a metal corrugated plate or a metal bellows, You may.

Specifically, as shown in Figs. 7A to 7C, a plurality of small metal pieces such as chains, scales, and the like can be connected to provide flexibility while having thermal conductivity. Alternatively, as shown in Fig. 7 (d), the metal piece may be made of a single piece of metal rather than a plurality of small pieces of metal, but may be made flexible by being processed into a bellows or a bellows shape. Alternatively, as shown in Fig. 7 (e), the thermally conductive member 70 may be made of a metal fiber or a metal thin film.

The flexibility of the thermally conductive member 70 which greatly affects the flexibility of the entire hot / cold pack can be improved, so that the adhesion between the hot pack pack and the bodily contact area can be further improved Can be obtained.

More preferably, a portion directly in contact with the Peltier element, that is, a portion in direct contact with the heat absorbing surface 50 and / or the heat dissipating surface 60 of the Peltier element is made of a metal plate having rigidity, It is also possible to prevent breakage of the Peltier element that may be caused by the flexible structure of the entire thermally conductive member 70. The gap between the cover 10 and the thermally conductive member 70 , A fluid member 90 which receives heat from the thermally conductive member 70 or is heated or cooled by heat is interposed. Any material may be used as the fluid member 90. However, as described in the present embodiment, a gel (90) type material is interposed between the cover 10 and the thermally conductive member 70 . In the case of a gel type material, even if the contents are leaked due to breakage of the cover 10, a certain degree of solidification is maintained, so that cleaning and the like are easy, and since it has excellent flexibility, It is possible to obtain an effect of enhancing the adhesion to the site.

According to the structure of the present invention, the cold and warm fomentation pack can be configured with a simple structure by adopting the Peltier element and the fluid member. In addition, the hot and warm fomentation pack of the present invention can control a wide temperature range from -75 ° C to 300 ° C depending on the kind and purity of the metal used in the Peltier device, the type of chip, and the power supply system (AC, DC, etc.) It is easy to adjust the temperature according to the use of the padding. Unlike the conventional hot pack, it is possible to adjust the temperature accurately for this kind of cold pack. In the present invention, by employing a method in which the fluid member having a relatively high thermal conductivity and heat capacity is adjacent to the heat conductive member for transferring cold and warm from the heat absorbing surface to the heat conductive member, heat loss is minimized, It is possible to obtain an effect of increasing the contact area according to the bending of the body part and lowering the contact unevenness to the skin.

In addition, since the hot pack of the present invention uses a Peltier element unlike the conventional hot pack, both sides of the hot pack can be used for cold and hot panty respectively (both sides corresponding to the heat absorbing surface and the heat generating surface of the Peltier element). That is, the Peltier element 20 includes a heat absorbing surface 50 and a heat dissipating surface 60. When the heat absorbing surface 50 faces the body applying part, the Peltier element 20 functions as a hot pack, Side is directed to the body application site, it functions as a hot pack. As described above, the fomentation pack according to the present invention serves both functions of the cold fomentation pack and the warm fomentation pack at the same time. On the other hand, in the present embodiment, the heat-absorbing face side and the heat-radiating face side of the hot and warming pack are described as functioning as a cold pack member and a warm pack member, respectively. However, by reversing the direction of the current applied to the Peltier element, It is obvious to those skilled in the art to have ordinary knowledge.

Basically, in a method used for a cosmetic purpose, a method of performing a "hot pack after the mask pack is packed after warm pack" is taken. In other words, the pores are opened through the "hot fomentation", and various kinds of ingredients suitable for the skin are penetrated into the skin with the mask pack, and the pores are closed through the "cold fomentation" to enhance the elasticity of the skin. However, conventionally, there has been a problem that a separate machine must be used in a skin care room or a hospital that specializes in cosmetics in order to perform cold-warming after such warming. However, according to the embodiment of the present invention, the both surfaces of the hot and warmable pack can be used for hot and cold panting (double-sided warming), respectively, so that the effect of hot and cold panting can be obtained quickly and easily with one device do.

The heat insulating member 80 is interposed between the side of the heat absorbing surface 50 and the side of the heat radiating surface 60 so that the side of the heat absorbing surface 50 and the side of the heat radiating surface 60 It is preferable to thermally isolate it. In other words, between the heat conductive member on the heat absorbing surface 50 side of the Peltier element 20 and the heat conductive member on the heat dissipating surface 60 side, and between the heat conductive member on the heat absorbing surface 50 side and the heat radiating member 60 side It is preferable that the heat insulating member (80) is interposed between itself and the fluid member.

As described above, the Peltier element 20 has a drawback that the power efficiency is poor with the cooling mechanism because the amount of heat dissipation of the element itself is larger than the heat to be moved. In other words, since the heat absorbed by the heat absorbing side and the power consumed heat are generated on the heat radiation side, there is a problem that cooling of the Peltier element itself is difficult. In addition, if a load is applied without sufficiently cooling the array side, the cooling efficiency on the heat absorption side is lowered, and the element itself may be damaged or burned. For this reason, in the prior art, a cooling part such as a cooling fan is additionally provided on the arrangement side, which makes it difficult to apply to the hot pack.

On the other hand, according to the present invention, when cooling is attempted, one side is cold and the other side is warm. When the above-mentioned fluidized member is adjacent to the cold and warm air and the heat insulating member is formed at the interface, the fluid member and the thermally conductive member on the heat absorption surface side of the Peltier element can be maintained in a state suitable for cold- The fluid member and the thermally conductive member on the side of the heating surface can be kept in a state suitable for the hot pad. Heat accumulated on the heat dissipation surface of the Peltier element is transmitted to the fluid member through the heat conduction member on the heat dissipating side surface side and is diffused, thereby preventing overheating. That is, it is not necessary to take a complicated configuration in which a cooling section such as a heat radiating fan is additionally provided on the array side. Therefore, it is possible to suppress an increase in costs necessarily caused by the installation of the cooling part, to further facilitate the maintenance of such additional cooling part, etc., and further to achieve the effect of achieving compactness of the hot pack .

In the present invention, the heat insulating member 80 preferably includes at least one of a urethane resin or an epoxy resin.

Will be described with reference to Table 1 below. Table 1 is a table showing properties of materials applicable as insulating members.

As can be seen from Table 1, the urethane-based material has an advantage that it is easy to process while being within the use range of the heat insulating member according to the present invention. The epoxy resin has an advantage that the thermal conductivity is lower than that of the urethane type and is strong in water resistance. In addition, if epoxy resin is filled in the drying environment between the heat absorbing surface and the heat generating surface of the Peltier element and sealing is performed, the effect of preventing occurrence of the occurrence around the Peltier element can be expected.

In the present invention, electric wires for supplying electric power are connected to the Peltier elements of the hot and warmable fomentation pack. The power source for the Peltier device may be, but is not limited to, a household power source (220V / 110V), a car cigarette charger (12V / 24V), a USB port used for a smartphone charger, and a battery .

In the above embodiment, it is preferable that the hot and cold pack 1 further comprises a temperature controller and a temperature sensor for controlling the temperature of the Peltier element 20. [

When the temperature detected by the temperature sensor exceeds the limit value, it is difficult to prevent the overheat of the Peltier element from being transmitted to the thermally conductive member and the fluid member, (Timer setting) for automatically turning off the heater or automatically switching the cool / warm switch to reverse the cool / hot switch, thereby preventing overheating.

Alternatively, the heat dissipation efficiency may be relatively increased by intermittently applying the current appropriately by the control device. When the current is continuously supplied to the Peltier device, the required amount of heat dissipation due to the heat generated by the Peltier device itself also increases. However, by applying the current intermittently, heat can be effectively absorbed. In addition, the position and number of the temperature sensors can be appropriately selected in accordance with the purpose of actual implementation.

In addition, since it is recommended not to use the hot and cold packs for a certain period of time, it is more effective to take such an overheat preventing structure in terms of safety. If mutual heat transfer between the heat absorbing surface side and the heat radiating surface side is a problem, the Peltier element of a laminated structure in a small size may be used to increase the area covered by the heat insulating member to increase the heat insulating effect.

&Lt; Example 1 >

According to the first embodiment of the present invention, it is preferable that the cold / hot pack member 1 includes a plurality of hot component segments, and each of the plurality of hot component segments includes the Peltier element, the thermally conductive member, and the flowable member 4).

Conventionally, a high-purity aluminum plate having high heat conductivity and high thermal conductivity has been used as a heat conduction member by bonding it to a Peltier element. However, since the metal plate can not be deformed when it is formed into a metal mold, And the body application area was limited to the hip area or the waist area. Accordingly, in order to obtain an appropriate cosmetic or physical treatment effect, it is required that the cold / hot feminine pack be arranged so as to conform to the bending of the user's body applying portion.

In the first embodiment of the present invention, the fluid member is disposed adjacent to the heat transfer member, and the fluid member is brought into contact with the pad member to enhance the adhesion to the pad member. In the first embodiment, the hot and cold pack 1 includes a plurality of hot pack segments, each of the hot pack segments including a Peltier element, a thermally conductive member, and a fluid member, It is possible to obtain an effect of further enhancing.

In the first embodiment, it is preferable that the plurality of fomentation segments are connected to each other and have a shape and size suitable for a body bending part to be foment.

If a plurality of fomenting segments are connected to each other with a predetermined flexibility with respect to a fomenting part having a complicated shape such as a face or the like and have a shape and size suitable for a part to be fomented, the adhesion of the fomenting part to the skin can be further improved Do.

Each of the fomentation segments according to the first embodiment of the present invention is connected to each other by electric wires for power supply so that the heat generating surface and the heat absorbing surface of each fomentation segment are on the same side.

&Lt; Example 2 >

In Embodiment 1, each of the fomentation segments constituting the hot and cold fomentation pack has an optimized shape and size according to the foment area, while in the embodiment 2, each foment segment has the same shape and size as shown in FIG.

When the shape and size of the plurality of fomentate segments are substantially the same, the connection at the connection site is easy, and the effect of manufacturing the hot and warmable packs is suppressed and the manufacturing cost is suppressed. In actual use, it is also possible to separate and use segments of the hot pack as appropriate according to the area of the hot pack. For example, when the arm is to be fomented, it can be divided into three segments arranged in a straight line according to the thickness of the arm. In the case of a cushion or a backrest, a suitable number of segments And may be cut and used.

It is also preferable that the shape of the segment is substantially a square. FIG. 4 is a diagram showing an example, basically based on a quadrangle, a square, a rectangle, a parallelogram, and a rhombus. By doing so, it is possible to reduce the inconvenience that the two modules come into contact with each other due to the difference, and it is advantageous in terms of manufacturing to unify rather than individualize the parallel connection contact portions. However, the shape of the module is not limited to the shape and may have other shapes such as a triangle, a pentagon, and a hexagon.

Each of the fomentation segments according to the second embodiment of the present invention is connected to each other by electric wires for power supply so that the heating face and the heat absorption face of each fomentation segment are on the same side.

&Lt; Example 3 >

In the second embodiment, each segment is connected from the beginning, and it is necessary to cut and use it appropriately according to the site of use. However, in the third embodiment, as shown in FIG. 6A, And a connection portion for connecting the segments to each other.

In Embodiment 3, it is preferable that each of the plurality of fomentation segments includes a connection portion for connection with another fomentation segment.

It is preferable that a plurality of the coupling portions can be combined by the magnet coupling or the fitting coupling. For example, simply by a magnet, or by a fitting member having an outline of male and female, to be applied depending on the bending of the body applying part. It is also possible that the respective fomentation segments are connected to each other in such a manner that they can rotate relative to each other around the connecting portion. Although the connection (joining) of a plurality of cells or segments by a fitting member having a magnet or a male / female contour has been exemplified above, this description is merely an example for explanation, It does not preclude other possible connections.

Further, the forming position of the connecting portion may be located in the middle portion of each of the fomenting segments, and may be disposed in the corner portion of the fomenting segment, but not limited to these positions, and each of the fomenting segments can be easily connected to each other, It may be formed at any position if it is easy.

In addition, in the case of a segment which can be commonly used (that is, in the case of a fomenting segment to be used in the middle portion in the finally assembled hot pack), connection portions are formed in all of the upper, lower, left and right sides, In the case of a segment used for a portion or a corner portion, a connecting portion may be formed only in a part of the upper, lower, left, and right sides.

When the segments can be separated from the beginning, the hot pack formed by connecting the hot packs has an additional advantage that it is possible to replace only a portion of the plurality of hot pack segments constituting the pack, easily, Can be obtained. In addition, if it is possible to separate the body, it is possible to use a suitable number of the fomentation segments appropriately according to the size and the bend of the part to be fomented by the user, for example, the shoulder, neck, It is possible to further increase the power consumption and to consume less power.

According to this configuration, since the individual cells or the segments can be connected to each other after taking an appropriate number of necessary parts for the body applying part having a complicated outer margin, it can be adhered to the body application part and the unnecessary power consumption can be suppressed . Further, in the case of such cell or segment connection, the electrical wiring to the Peltier element is concretely divided into a plurality of Peltier elements, It is also possible to adopt a method of

A connection portion (connection connection portion) for physically connecting each of the fomentation segments and a connection portion (electrical connection portion) for electrically connecting the fomentation segments may be a single connection portion, but they may be different connection portions.
