Description

Apparatus for cold and hot pack}

The present invention relates to a hot and cold compress device, and more specifically, to a cold and hot compress device that can selectively apply cold or warm compresses to human skin using a thermoelectric element.

A typical refrigeration cycle type air conditioner is structured to cool and circulate the air in a specific area and discharge the heat absorbed in the space within a specific area to another space (outdoor unit space).

In other words, there must be a division of space in order to operate the air conditioner to supply cold air to the space within a specific area. Therefore, small (portable) air conditioners are not only reduced in size, but also have a structure in which heat generated in the process of condensing refrigerant gas must be removed to the outside using a separate duct, making it inconvenient to use them freely in indoor spaces.

Meanwhile, cooling and heating devices using thermoelectric elements do not require a compressor, evaporator, or refrigerant, so they are widely applied to small air conditioners, portable refrigerators, and car seat cooling and heating devices. A cooling and heating device using a thermoelectric element must absorb heat from the heat absorbing part and dissipate the heat absorbed from the heat absorbing part well in order to achieve effective cooling and heating.

Here, conventional heating and cooling devices using thermoelectric elements mainly use an air cooling method using air flow to cool the heat dissipation portion. In this case, the same problem as the refrigeration cycle air conditioner occurs, that is, when there is a heat absorber and a heat dissipator in the same space. Not effective for cooling. In addition, for heat dissipation effect, it is common to provide a heat dissipation fan, but in this case, noise problems occur.

In consideration of this problem, a technology for applying a water cooling method in which the heat dissipation part is cooled using water is introduced. However, in the case of this prior art, the structure for circulating water to cool the heat dissipation unit is complicated and a device such as a pump for circulating water is required, making it difficult to implement a portable air conditioner.

Meanwhile, a technology that can apply hot or cold compresses to human skin using such thermoelectric elements is introduced in the following prior art literature. However, as mentioned above, in that a heat dissipation fan is still provided to dissipate heat from the heat dissipation unit, the configuration is complex and bulky, making it difficult to use it portablely.

Republic of Korea Patent Publication No. 10-2018-0065380 (published on June 18, 2018)

The present invention was designed to solve the above problems, and provides a hot and cold compress device that can apply cold or hot compresses by contacting the user's skin with cold or warm heat using a thermoelectric element, and is simple to construct and can also be used as a portable device. There is a purpose to doing so.

A hot and cold fomentation device according to the present invention for achieving the above object includes a storage container (100) in which a receiving portion (101) with an open top is formed to accommodate cold water, ice water or hot water; An upper cover 110 that selectively opens and closes the top of the receiving portion 101 formed in the storage container 100; It is installed at the lower part of the storage container 100, is detachably coupled to the storage container 100, and has a fixed thermoelectric element 130 installed inside so that the upper surface is in contact with the outer lower surface of the storage container 100. Holder (120); And, it is installed at the lower part of the fixing holder 120, but the lower surface is exposed to the outside of the fixing holder 120 in contact with the user's skin, and the upper surface is in contact with the lower surface of the thermoelectric element 130 to provide cold heat or heat. It includes a contact block 150 that selectively supplies heat.

The hot and cold compress device according to the present invention may further include a vibration member 160 installed on one side of the contact block 150 to apply vibration to the contact block 150.

The hot and cold compress device according to the present invention may further include a temperature sensor 170 that is connected to the thermoelectric element 130 to detect the temperature of the thermoelectric element and to cut off the power supply when the temperature exceeds the set temperature range. .

In addition, the hot and cold fomentation device according to the present invention may further include a handle 190 extending from one side of the fixing holder 120.

And the fixing holder 120 or the handle 190 includes a power switch 200 that supplies power to the thermoelectric element 130; And a cold compress switch 210 and a warm compress switch located on the side of the power switch 200 and switching the polarity of the thermoelectric element 130 so that the contact block 150 can selectively supply cold heat or warm heat. (220) can be installed.

According to the present invention, heat dissipation of a thermoelectric element (thermoelectric module) is efficiently performed by using the specific heat of water by putting water in the water receiving part and bringing it into direct contact with the water. Therefore, it is used for air-cooled heat dissipation in a conventional air-cooling and heating device using a thermoelectric module. Since there is no heat dissipation fan, there is no operating noise, and it has the advantage of simple structure and small volume because it does not use complicated water pipes and pumps used for conventional water cooling heat dissipation.

Prior to describing the present invention, the following specific structural and functional descriptions are merely illustrative for the purpose of explaining embodiments according to the concept of the present invention, and embodiments according to the concept of the present invention may be implemented in various forms. It should not be construed as limited to the embodiments described herein.

In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments will be illustrated in the drawings and described in detail in the specification.

Figure 1 is a perspective view showing a hot and cold fomentation device according to an embodiment of the present invention, Figure 2 is a front view of Figure 1, and Figure 3 is a cross-sectional view taken along line A-A of Figure 2.

As referred to herein, the present invention is provided with a storage container 100, and a receiving portion 101 in which cold water (or ice) or hot water is stored is formed inside the storage container 100, and the receiving portion 101 ) is open, and a female threaded portion 102 is formed on the upper inner side of the receiving portion 101 for screwing the upper cover 110, which will be described later.

An upper cover 110 is installed on the top of the receiving part 101 formed in the storage bin 100 to be selectively openable, and the bottom of the upper cover 110 is attached to the female thread 102 of the storage bin 100. A male thread portion 111 that is screwed together is formed. That is, the receiving part 101 can be kept airtight by the upper cover 110.

Meanwhile, a fixing holder 120 is installed at the bottom of the storage container 100 so that it can be separated and combined. In order for the storage container 100 and the fixing holder 120 to be separable and coupled, a male thread portion (not shown) is formed at the bottom of the storage container, and a female thread portion is formed at a corresponding position at the top of the fixing holder 120.

A thermoelectric element 130 is built into the fixing holder 120, and the upper surface of the thermoelectric element 130 is maintained in close contact with the outer lower surface of the storage container 100. A power supply (power line or charging terminal), not shown, for supplying power is connected to the thermoelectric element 130, and a contact block 150 is installed at the lower part of the fixing holder 120. As is known, one side of the thermoelectric element 130 can be a heat absorbing side (cooling) and a heat dissipating side (heating) by supplying power and changing the polarity of the power, and the opposite side can be a heat dissipating side and a heat absorbing side. It can be cotton. Since the detailed operating principle of the thermoelectric element is a known technology, its detailed description will be omitted.

A power switch 200 is installed on the outer peripheral surface of the fixing holder 120, and a cold compress switch 210 and a hot compress switch 220 are installed on one side of the power switch 200, respectively. Therefore, the user can select power supply and hot/cold compress by operating the various switches. When the switch for hot or cold compress is selectively pressed, the contact block 150 connected to the fixing holder 120 can apply cold or warm compress accordingly.

The contact block 150 is in contact with the user's skin and, as described above, provides cold or warm compresses by the user's selective switch operation, and its bottom is formed so that the central portion protrudes downward.

Therefore, the upper surface (on the drawing) of the contact block 150 is maintained in close contact with the lower surface of the thermoelectric element 130, and the lower surface of the contact block 150 is on the outside of the fixing holder 120. It is installed exposed.

Meanwhile, in order to achieve compressing performance and massage effect, it is also possible to install a vibration member 160 on one side of the contact block 150 to transmit vibration to the user's skin when the user applies a cold compress or a warm compress. On the other hand, when a user applies a cold compress or a hot compress, excessive temperature may cause damage to the user. Therefore, a temperature sensor 170 is installed on the side connected to the thermoelectric element 130 to cut off the power supply when the temperature is above or below the set temperature. do.

The operation of applying cold or warm compresses to the user's skin according to the embodiment of the present invention configured as described above will be described.

First, when applying a cold compress, the storage container 100 is separated from the fixing holder 120, cold water or ice water is placed in the receiving portion 101 formed in the storage container 100, and the upper cover 110 is screwed together to accommodate the storage container 100. To prevent cold water or ice filled in the unit 101 from leaking to the outside, the storage container 100 is screwed to the fixing holder 120. It is also possible to separate only the upper cover 110 from the storage container 100 and put cold water or ice water directly into the storage container 100 without separating the storage container 100 from the fixing holder 120.

In this state, when the power switch 200 installed on the fixing holder 120 is turned on and the cooling switch 210 is switched to the on state, the lower surface of the thermoelectric element 130 becomes a heat absorbing surface and cold air is generated. , the cold air from the thermoelectric element 130 is transferred to the contact block 150 connected thereto, so that the contact block 150 can apply cold compresses to the user's skin.

Meanwhile, the upper surface of the thermoelectric element 130 becomes a heat dissipation surface, and in order to maximize the cooling efficiency of the thermoelectric element, the heat of the heat dissipation surface must be well dissipated. The receiving portion in contact with the upper surface of the thermoelectric element 130 ( The cold air of cold water or ice stored in 101) can efficiently dissipate heat from the upper surface of the thermoelectric element 130.

According to the present invention, by arbitrarily adjusting the temperature of the water contained in the receiving portion 101, the temperature transmitted through the contact block 150 can be made colder or hotter.

For example, when the contact block 150 of the present invention uses the lower surface of the thermoelectric element 130 in contact with the contact block 150 as a heat absorbing surface to perform cold and heat steaming, the thermoelectric element 130, which is a heat dissipating surface, The better the upper surface of the thermoelectric element 130 is cooled, the better the cooling efficiency (heat absorption efficiency) of the lower surface of the thermoelectric element 130 becomes. Therefore, the lower the temperature of the water contained in the receiving part 110 of the storage container 100 in contact with the upper surface of the thermoelectric element 130, the better the cooling efficiency, and therefore the user can use the contact block 150 of the present invention more effectively. In order to generate cold heat, cold water or ice water can be appropriately added to the water receiving part 110.

On the other hand, on the other hand, when the contact block 150 of the present invention uses the lower surface of the thermoelectric element 130 in contact with the contact block 150 as a heat radiation surface (heating surface) to perform a heat treatment, the cold and heat treatment function and In an opposite concept, the higher the temperature of the water received in the water receiving part 110, the better the thermal fomentation efficiency. Therefore, the user can properly apply hot water to the water receiving part 110 in order for the device of the present invention to generate hotter wind. You can use it by adding it.

Meanwhile, in order to add a massage function, the vibrating member 160 installed on one side of the contact block 150 is activated to vibrate the contact block 150, thereby providing a cold compress while vibrating the user's skin. The vibration member 160 can operate automatically when power is supplied, and a separate vibration member switch (not shown) can be installed.

Since the present invention is implemented in an ultra-small size, as described above, when used as a cold and heat steamer, if cold water such as ice water is added to the receiving portion 101, much colder and cooler air can be used immediately and for a longer period of time. However, if the temperature of the water contained in the water receiving part rises, the heat exchange efficiency decreases and ultimately the cooling effect decreases. In addition, since the present invention is implemented in an ultra-small size, the amount of water accommodated in the receiving portion 101 of the storage container 100 is limited. Therefore, a situation in which cooling efficiency is reduced is recognized based on the temperature information of the temperature sensor 170, an alarm is given to the user, and the power is automatically turned off. Of course, in the opposite case when using a warm compress, there is a risk of burns if the heating efficiency decreases or the temperature becomes too high, so an alarm is given to the user and the power is automatically turned off.

Next, when applying a hot compress, the action is the opposite of applying a cold compress.

That is, hot water is put into the receiving portion 101 formed in the storage container 100. Here, we will omit detailed descriptions of operations that overlap with cold compresses.

In this state, when the power switch 200 installed on the fixing holder 120 is turned on and the heat treatment switch 220 is switched to the on state, the lower surface of the thermoelectric element 130 becomes a heat dissipation surface and heat is generated. And, the warmth of the thermoelectric element 130 is transferred to the contact block 150, providing a warm compress to the user's skin.

Meanwhile, the upper surface of the thermoelectric element 130 becomes a heat absorption surface, and in order to maximize the thermal efficiency of the thermoelectric element, the cold air on the heat absorption surface must be well removed. The receiving part ( The warmth of the hot water stored in 101) can efficiently remove cold air from the upper surface of the thermoelectric element 130.

According to the present invention, in order to efficiently dissipate heat from the heat dissipation surface of the thermoelectric element, cold water (ice water) contained in the storage tank 100 is used instead of using the existing air-cooled heat dissipation fan or water-cooled water pipe. Conversely, the heat absorbing surface of the thermoelectric element uses hot water. In the end, it can be implemented in an ultra-small size for simple configuration, and can be implemented so that it can be carried and moved while being carried by an individual.

Next, a hot and cold compress device according to another embodiment of the present invention will be described.

Figure 4 is a perspective view showing a hot and cold fomentation device according to another embodiment of the present invention, Figure 5 is a front view of Figure 4, Figure 6 is a side view of Figure 4, and Figure 7 is a cross-sectional view taken along line A-A of Figure 6.

Unlike the cold and hot fomentation device according to another embodiment of the present invention, the hot and cold fomentation device according to another embodiment of the present invention is additionally provided with a handle 190 on one side of the fixing holder 120 so that the user can easily use it. It was installed. The hot and cold compress device according to an embodiment of the present invention does not have a handle, so the user must hold the storage container 100 to operate the hot and cold compress device, which may cause inconvenience when used by women, the elderly or children with small hands. Therefore, the hot and cold steaming machine according to another embodiment of the present invention is additionally equipped with a handle 190.

Therefore, since all other components other than the handle 190 are the same as the previous embodiment, detailed description thereof will be omitted.

A power supply unit is installed at the end of the handle 190, and a power line or charging terminal 140 may be applied to the power supply unit. When the charging terminal 140 is applied, a rechargeable battery (not shown) is built into the handle 190.

According to the cold and hot steaming device according to another embodiment of the present invention configured as described above, the user can conveniently operate it by holding the handle.

Although preferred embodiments of the present invention have been described above, the present invention is not limited to the specific embodiments described above. In other words, a person skilled in the art to which the present invention pertains can make numerous changes and modifications to the present invention without departing from the spirit and scope of the appended claims, and all such appropriate changes and modifications can be made. Equivalents should also be considered to fall within the scope of the present invention.
