Abstract

The hot/cold fomentation pack according to the present invention comprises: a Peltier module having a heat absorption surface and a heat dissipation surface; one or more thermally conductive members which are adjacent to at least one of the heat absorption surface and heat dissipation surface of the Peltier module and have a surface area larger than the surface area of the heat absorption surface or heat dissipation surface of the Peltier module; and a fluid member which is adjacent to the thermally conductive member(s) and becomes heated or cooled as a result of receiving heat from or losing heat to the thermally conductive member(s). Accordingly, as long as power is supplied, a fomentation area can be given a hot/cold fomentation at an exactly desired temperature regardless of place, and thus a fomentation effect can be maximized. Further, the hot/cold fomentation pack can be adapted so as to correspond to the curve(s) of the fomentation area, and thus effects such as excellent heat transfer and wearability can be obtained.

Description

Cold Pack

The present disclosure relates generally to cold pack packs, and more specifically, to cold pack packs that can be used to efficiently or effectively cool or warm a pack of a user's body using a Peltier element and a fluid member. It is about.

Conventionally, the pack is used to cool or warm the pack by using a microwave oven, boiling water, cold / freezer, etc. to select any one of the cold pack and the hot pack for the required area. there was.

As a method of use, when using a microwave oven warmed for 4 to 5 minutes to use, and boiling water to use for 10 minutes to use. In addition, during cold compressing, the refrigerator is used for about 2 to 3 hours and then used in the freezer for about 30 minutes.

However, such a conventional pack is not possible to use as a cold pack or a hot pack only the whole of the pack in the above-mentioned heating or cooling method, it was impossible to use as a cold pack pack, microwave, boiling water for heating or cooling of the pack It is inconvenient to carry because it requires a refrigerator / freezer.

In addition, as described above, at least four to five minutes of preparation time is required for hot steaming, and even at least 30 minutes of preparation time for cold steaming, a considerable preparation time is required for performing one steaming.

In addition, when warmed with boiling water for hot steaming, if the steam pack is not wrapped in a towel and warmed, there is a high risk of damaging the product itself due to direct contact with the cover of the pan and the steam pack, and the temperature left in the freezer for cold steaming is 30 If it is thrown out for more than a minute or left at minus 15 ° C. or less for a long time, the poultice pack hardens and hardens, resulting in a heterogeneity without being adhered to the shape of the bend of other poultices.

In addition, in the case of cold poultry, there is a problem in that the use of the water is very uncomfortable due to the moisture in the outer shell, and there is a serious problem that the temperature of the poultice pack itself is not always maintained at a temperature suitable for the desired poultice. In other words, if you apply the pack directly from your microwave, boiling water, or freezer to your skin, you may injure yourself with burns or frostbite due to high or low temperatures. There is also a problem that it is difficult to obtain a sufficient poultice effect.

Apart from this, a technique of heating or cooling an object by using a Peltier element applying the Peltier effect has been studied. The Peltier effect is a thermoelectric phenomenon opposite to the Seebeck effect. The Peltier effect refers to the effect of absorbing and dissipating heat at the junction when different voltages are joined together. In other words, it is a phenomenon of creating a temperature difference from voltage, and this Peltier effect is one of the thermoelectric effects together with the Thomson effect. Peltier devices are also called thermoelectric modules, pelce devices, and thermoelectric modules. When a direct current flows, endothermic heat occurs on one side and heat generation occurs on the other side (that is, heat transfer from the endothermic surface to the heat generating surface occurs. If the polarity of the current is reversed, the relationship is reversed and it is very suitable for precise temperature control. The performance of the Peltier device is expressed by the maximum endothermic amount (Q _max ), the maximum current (A _max ), and the maximum voltage (V _max ).

Here, since the heat generation amount increases and the cooling efficiency decreases as the applied voltage increases, 50-60% of the maximum voltage is known as the optimum voltage.

Currently, Peltier devices are used mainly in small heating / cooling devices as their applications. For example, in the case of the application to the cooling device, compared to the cooling method using a reverse carno cycle used in home electric refrigerators or air conditioners, the size of the device can be easily downsized and noise and vibration are not generated. It is used in small cold / hot refrigerators and medical stimulation and cooling devices to be mounted on vehicles and the like.

However, in spite of these advantages, there is a drawback that the cooling mechanism is poor in power efficiency and cooling efficiency 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 from the heat absorbing side and the heat of power consumption generate heat on the heat radiating side, the heat dissipation of the Peltier element itself is difficult, and thus it has not been widely used as a cooling means. Furthermore, unlike heat exchange such as a heat pump, if the load is applied without sufficient heat dissipation on the heat generating side, the cooling efficiency on the heat absorbing side will not only be greatly reduced, and even the element itself will be damaged or burned out. There is great concern.

In recent years, paying particular attention to the advantages of the above-described Peltier element, that is, its small size and easy temperature control, the edema after Peltier element after various surgical treatments such as fever, cosmetic, cosmetic surgery due to body fever, etc. Efforts have been made to apply to a poultice device for the purpose of treatment, physical therapy, and the like. This effort has been shown in the form of a helmet (in Fig. 1 and Patent Document 1) that emits cold air or warmth in contact with the head portion.

However, the poultice device described in Patent Document 1 also does not adhere to the skin, so it is difficult to expect a uniform poultice effect, as if the head part is pushed into a narrow oyster, giving a great sense of rejection such as a sense of closure, and the device itself. The size of the was too large to be installed in a dedicated facility is practically impossible to carry, and even if a small portion of the failure had to inconvenience the entire maintenance. That is, the steaming device described in Patent Document 1 still did not fully utilize the above-described advantages of the Peltier element in its configuration, and therefore the effect was also not remarkable. In particular, because it does not take a structure that can be in close contact with the application site, the poultice effect also does not significantly meet expectations.

<Configuration of Cold Pack

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

As can be clearly seen from FIG. 2, the cold pack package 1 includes a cold pack pack 10 (hereinafter also referred to as a cover) 10 and a Peltier element 20 provided in the cover 10.

The cover 10 surrounds the Peltier element 20 to prevent breakage of the inner member from scratches, impacts from falling, etc., that is, serves as a basic cover (exterior material) and is required for cold / hot steaming. Including at least one or more portions in contact with the user's body poultice region, and also has a function to facilitate heat transfer between the portion of the body and the poultice region. Since the cover 10 is in direct contact with the human body in the present embodiment, it is preferable that the cover 10 is made of a material such as a resin that is harmless to the human body. As for the material such as resin used for the cover 10, any material may be used as long as it is a material that is harmless to the human body and that can seal the fluid type member, particularly the gel type described below. For example, as the cover material of the cold pack pack of the present invention, PVC, urethane, or a mixture thereof, which is a thermoplastic resin, or a material including an ocher component, a herb component, and a charcoal component may be used.

The Peltier device used in the cold pack of the present invention has a potential difference between the charge carriers (electrons and / or holes) when a DC voltage is applied across the two metals in a state where two different metals are bonded with two contacts. The heat is moved from one metal side to the other while moving the metal present. Referring to FIG. 3, when current flows in a counterclockwise direction, holes in the P-type semiconductor are generated at four contacts and move toward the second contact, and electrons in the N-type semiconductor are in the opposite direction, that is, at the third contact. Move toward contact point 1. Here, holes / electrons carry heat, and as a result, 3 to 4 plates are continuously cooled, and 1 to 2 plates are continuously heated. In addition, if the polarity of the applied voltage is reversed, the heat absorbing portion and the heat generating portion are interchanged with each other, and the flow of heat is reversed. It is the Peltier device which used such an effect.

In one embodiment of the present invention, it is preferable that the thermal conductive member 70 is adjacent to at least one of the heat absorbing surface 50 and the heat radiating 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 the member has a high degree of thermal conductivity and a required degree of strength. For example, the thermally conductive member may be made of aluminum, copper, or the like as a metallic material.

In addition, the thermal conductive member 70 preferably has a surface area larger than that 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 good heat transfer between the heat absorbing surface 50 and / or the heat dissipating surface 60 of the Peltier element and the fluid member described later, the viewpoint of increasing the contact area It is preferred that the surface area of the heat absorbing surface 50 and / or the heat dissipating surface 60 of the Peltier element is larger than that. In addition, the method of adjoining the thermally conductive member 70 to the heat absorbing surface 50 or the heat dissipating surface 60 of the Peltier element 20 may use a known technique without particular limitation, but may have a certain degree of roughness. It is desirable to increase the heat transfer performance by filling gaps between them.

In addition, the thermally conductive member 70 may be composed of a single member, for example, in the form of connecting a plurality of metal pieces to have the same flexibility, in the form of metal corrugated plate or metal bellows, in the form of metal fiber or metal thin film. You may.

Specifically, as shown in FIGS. 7A to 7C, a plurality of small metal pieces such as chains and scales may be connected to each other so as to have flexibility while having thermal conductivity. Alternatively, as shown in (d) of FIG. 7, it is possible to have flexibility by forming a bellows or a bellows shape with one metal piece instead of a plurality of small metal pieces. Alternatively, as shown in FIG. 7E, a metal fiber may be employed for the thermally conductive member 70, or a metal thin film may be employed.

When configured as described above, the flexibility of the thermally conductive member 70, which greatly affects the flexibility of the entire cold pack pack, can be increased, and thus the effect of further improving the adhesion between the cold pack pack and the severely contacted body parts. Can be obtained.

More preferably, the portion of the Peltier element that is in direct contact, that is, the portion of the Peltier element that is in direct contact with the heat absorbing surface 50 and / or the heat dissipating surface 60, is a metal plate having rigidity. By forming the flexible material or structure, the entire thermal conductive member 70 may be prevented from being damaged by the Peltier element, which may be caused by the flexible structure. In addition, the fluid member 90 receives or receives heat from the heat conductive member 70 and is heated or cooled. Any material may be used as the flowable member 90, but as described in the present embodiment, a gel 90 material is interposed between the cover 10 and the thermally conductive member 70. It is desirable to have. In the case of the gel type material, even if the cover 10 is damaged and the contents are leaked, it maintains a certain degree of solidity, so that it is easy to manage and clean the body. The effect which can improve adhesiveness with respect to a site | part can also be acquired.

According to the configuration of the present invention, due to the adoption of the Peltier element and the flowable member it is possible to configure the cold pack pack with a simple structure. In addition, the cold pack pack of the present invention can control a wide range of temperature from -75 ℃ to 300 ℃ depending on the type and purity of metal used in the Peltier device, the type of chip (chip), power supply method (AC, DC, etc.) It is easy to control the temperature according to the steaming use. Unlike conventional packs, it is possible to precise temperature control suitable for such a cold pack. In the present invention, by adopting a method of adjoining a fluid member having a relatively high thermal conductivity and heat capacity to a heat conductive member that transmits cold and warm heat from the heat absorbing surface and the heat dissipating surface, heat loss is minimized, and the metal plate is directly in contact with the skin. As compared with the case, the contact area can be increased and the contact heterogeneity to the skin can be lowered according to the curvature of the body part.

In addition, since the pack of the present invention uses a Peltier element unlike a pack of conventional packs, both sides (sides corresponding to the endothermic side and the heat generating side of the Peltier element) of the cold pack are available for cold pack and hot pack, respectively. That is, the Peltier element 20 includes a heat absorbing surface 50 and a heat dissipating surface 60, and when the heat absorbing surface 50 is directed toward the body application site, the Peltier element 20 functions as a cold pack. When the side is turned to the body application site will function as a hot pack. As such, the poultice pack according to the present invention is to simultaneously serve the function of the cold pack pack and the warm pack pack. Meanwhile, in the present embodiment, the heat absorbing side and the heat dissipating side of the poultice pack are described as functioning as the cold pack and the hot pack, respectively, but the reverse direction of the current applied to the Peltier element is such that the endothermic surface functions as the heat sink. It may be obvious to those skilled in the art.

Basically, in the method used for cosmetic purposes, a mask pack is performed after hot and cold treatment. In other words, the pores are opened through the "hot pack", and the mask pack penetrates the various ingredients that are good for the skin and closes the pores through the "cold pack" to increase skin elasticity. By the way, in the related art, in order to cold compress after such hot compress, there is a problem that a separate machine must be used in a skin care room or a hospital specializing in beauty. However, according to an embodiment of the present invention, by allowing both sides of the pack to be used for cold packs and hot packs (both sides hot and cold method), so that one device can quickly and simply obtain the effect of cold packs do.

In the said embodiment, in the cover 10, the heat insulating member 80 is interposed between the heat absorbing surface 50 side and the heat radiating surface 60 side, and the heat absorbing surface 50 side and the heat radiating surface 60 side are provided. It is desirable to shut off thermally. 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 radiating surface 60 side, and on the heat absorbing surface 50 side, the fluid member and the heat radiating surface 60 side It is preferable that the heat insulating member 80 is interposed between the fluid member.

As described above, the Peltier element 20 has a drawback of poor power efficiency as the cooling mechanism because the amount of heat dissipation of the element itself is greater than the heat to move. In other words, since the heat absorbed from the heat absorbing side and the heat of power consumption generate heat on the heat radiating side, cooling of the Peltier element itself is difficult. In addition, if the load is applied without sufficient cooling on the array side, the cooling efficiency on the heat absorbing side may not only decrease, but the element itself may be damaged or burned out. For this reason, the prior art has a complicated structure in which a cooling unit such as a cooling fan is additionally installed on the arrangement side, and it is difficult to apply to a pack.

In contrast, according to the present invention, when attempting cooling, one side is formed with cold air and the other is warm. If the above-mentioned fluid member is adjacent to each other in cold and warm, and a heat insulating member is formed on the interface, the fluid member and the heat conductive member on the heat absorbing surface side of the Peltier element can be kept in a proper state for cold compressing. The fluid member and the heat conductive member on the side of the heat surface can be maintained in a state suitable for warm steaming. The heat accumulated on the heat dissipating surface of the Peltier element is transferred to the fluid member through the heat conductive member on the heat dissipating surface side and diffused to prevent overheating. That is, it is not necessary to take the complicated structure which further installs cooling parts, such as a heat radiating fan, in an arrangement side. Therefore, it is possible to suppress the cost increase inevitably caused by the installation of the cooling unit, and the maintenance due to such additional cooling unit failure is much easier, and furthermore, the compaction of the steam pack itself can be achieved. Will be.

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

It demonstrates with reference to Table 1 below. Table 1 is a table showing the properties of materials applicable as a heat insulating member.

As can be seen from Table 1, the urethane-based material has the advantage of easy processing while within the range of use of the heat insulating member according to the present invention. In addition, the epoxy resin has the advantage that the thermal conductivity is lower than the urethane series, and strong in water resistance. In addition, when the epoxy resin is filled and sealed in a dry environment between the heat absorbing surface and the heat generating surface of the Peltier element, an effect of preventing generation of frost generated around the Peltier element is also preferable.

In the present invention, a wire for supplying power is connected to the Peltier element of the cold pack. As a power supply source for the Peltier device, a home power source (220V / 110V), a car cigar jack (12V / 24V), a USB port, a battery, and the like used for a smartphone charger can be assumed, but are not limited thereto. .

In the above embodiment, it is preferable that the cold pack pack 1 further includes a temperature control device and a temperature sensor for controlling the temperature of the Peltier element 20.

If the heat transferred to the heat generating surface of the Peltier element is difficult to prevent overheating only by being transferred to the thermal conductive member and the fluid member and spreading, if the temperature detected by the temperature sensor exceeds the limit value, power is supplied to the Peltier element. The overheating can be prevented by adopting the method of automatically turning off (timer setting) or by switching the cold and the hot by automatically switching the cold / hot switch to the reverse.

Alternatively, the heat dissipation efficiency may be relatively increased by appropriately intermittently applying current by the control device. If the current is continuously flowed to the Peltier device, the amount of heat dissipation required due to the heat generation of the Peltier device itself is increased, but heat can be effectively absorbed by applying the current intermittently. In addition, the arrangement position and the number of the temperature sensor can be appropriately selected according to the actual implementation.

In addition, since the cold pack pack is recommended not to be used for a predetermined time, it is more effective in terms of safety to take the overheat prevention structure in this way. If mutual heat transfer between the heat absorbing surface side and the heat radiating surface side becomes a problem, the Peltier element having a laminated structure in a small size can be used to increase the area covered by the heat insulating member, thereby increasing the heat insulating effect.

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

Conventionally, a high-purity aluminum flat plate with high thermal conductivity has been used as a thermal conductive member by joining it with a Peltier element. However, since the deformation is impossible when the shape is made into a metal mold, it is not necessary to bring it into close contact with body parts having different sizes and bends. Because of the limitations, the area of application of the body was confined to the hip and waist areas. From this, in order to obtain an appropriate cosmetic or physiotherapy effect, it is required to arrange the cold pack pack to match the curvature of the user's body application site.

In Example 1 of the present invention, the fluidity member was adjacent to the heat transfer member and the fluidity member was in contact with the poultice region, thereby increasing the adhesion to the poultice region. In Example 1, in addition to the cold pack pack (1) comprises a plurality of segments, each of the plurality of segments to include a Peltier element, a thermally conductive member and a fluid member, thereby improving the adhesion and steaming effect on the region The effect which can be heightened further can be acquired.

In Example 1, the plurality of poultice segments are connected to each other, it is preferable to have a shape and size suitable for the body flexion site to be poised.

If a plurality of poultice segments are connected to each other with a predetermined flexibility for a complex poultice site such as a face, and have a shape and size suitable for the site to be poised, the poultice site can be more closely adhered to the skin. Do.

Each poultice segment according to the first embodiment of the present invention is connected to each other by a wire for power supply so that the heat generating surface and the heat absorbing surface of each poultice segment are the same side.

In Example 1, each poultice segment constituting the cold pack pack has an optimized shape and size according to the poultice region, in Example 2, each poultice segment has the same shape and size as shown in FIG.

When the shapes and sizes of the plurality of poultice segments are substantially the same, the connection at the connection site is easy, the manufacture of the poultice pack is easy, and the increase in the manufacturing cost can be obtained. In actual use, segments of the pack may be used according to the site of the pack. For example, when the arm is to be steamed, the arm may be divided into three straight lines according to the thickness of the arm, and in the case of a cushion or a backrest, the segment may be divided into an appropriate number of widths and widths in consideration of seat size. It may be used after being cut to include.

In addition, it is preferable that the shape of a segment is substantially square. Figure 4 is for example shown, but basically based on the square, square, rectangle, parallelogram, rhombus based. By doing in this way, it is possible to reduce the inconvenience caused by different areas where the two modules contact each other, and it is advantageous in manufacturing to unify rather than to individualize the parallel connection contact areas individually. However, the shape of the module described above is taken as an example, and the shape thereof is not limited, and may have other shapes such as a triangle, a pentagon, and a hexagon.

Each poultice segment according to the second embodiment of the present invention is connected to each other by a wire for power supply so that the heat generating surface and the heat absorbing surface of each poultice segment are the same side.

In Example 2, each segment was connected from the beginning to be appropriately cut according to the use site, but in Example 3, as shown in FIG. 6 (a), each poultice segment was separated from the beginning, And a connecting portion for connecting each segment to each other.

In Example 3, each of the plurality of poultry segments preferably comprises a connection for connecting with other poultry segments.

It is preferable that the structure of the said connection part enables a plurality of coupling | bonding by coupling | bonding with a magnet or fitting coupling. For example, it may be simply connected to each other by a magnet or by a fitting member having a contour of male and female and applied according to the curvature of the body application site. It is also possible for each poultice segment to be connected in such a way that it can rotate relative to each other about the connection. In the above, the connection (combination) of a plurality of cells or segments by a magnet or a fitting member having a male and female contour is taken as an example, but this description is merely an example for explanation, and it is assumed by those skilled in the art. It does not exclude other possible connection methods.

In addition, the formation position of the connection portion may be located in the middle portion of each of the steam segment, or may be disposed in the corner portion of the steam segment, but is not limited to these positions, each steam segment can be easily connected to each other and relative rotation If the back is easy, it may be formed in any position.

In addition, in the case of segments that can be commonly used as needed (i.e., in the case of the steam segment to be used in the middle part of the finally assembled pack, the joints are formed on the upper, lower, left, and right sides, and the edges of the assembled pack are finally assembled. In the case of the segment used in the part or the corner part, the connecting part may be formed only in a part of the top, the bottom, the left and the right.

You can do it. In addition, in the case of the connection of such a cell or segment, the electrical wiring to the Peltier element is specifically connected in parallel by dividing the Peltier element into sizes suitable for the purpose, as shown in FIG. It is also possible to adopt a way of doing this.

The connection part (connection connection part) for physically connecting each steaming segment and the connection part (electric connection part) for electrical connection may be made into one connection part, but this may be made into a different connection part. For example, as shown in FIG. 6B, a connecting connection for physically connecting each poultice segment may be disposed at a corner of each segment, and the electrical connection may be disposed in the middle of one edge of the poultice segment. . The arrangement of these connection connections and electrical connections is not limited thereto.

In the above embodiment, a temperature sensor for controlling the temperature of the Peltier element may be provided for each steam segment, so that the steam temperature can be controlled for each steam segment. In other words, it is possible to configure the structure to enable cold compresses on the neck and on the back waist.

In addition, as shown in (c) of FIG. 6, by segmenting up and down segments of a plurality of segments upside down, it is also possible to function the segments as cold or hot packs different from other segments.

In addition, in the above description, the cold pack of the present invention mainly described for the purpose of applying to the skin pack, mainly for cosmetic purposes, especially for facial skin, the present invention is installed on the back of the backpack provides a sense of heat or cold heat depending on the season to the backpack wearer It can also be used for the purpose.
