Abstract

PURPOSE: An air conditioner is provided to let a user privately use an air conditioner by making the air conditioner wearable. CONSTITUTION: An air conditioner for individual use is formed by attaching an upper ceramic plate(21) of a thermoelectric module(20) to the center of a heat transfer belt(10) made by a soft material in the shape of a long belt and attaching a box fan(30) for transferring heat from the thermoelectric module to a lower ceramic plate in opposite to the upper ceramic plate. For cooling a specific part of the human body, the heat transfer belt is wound on the desired part. Upon applying power, the thermoelectric module and a blower fan(34) of the box fan are operated. The upper ceramic plate absorbs heat from the heat transfer belt, and the heat transfer belt is cooled. The lower ceramic plate emits heat to the box fan. By operation of the blower fan, external air flows in through an inlet port(31) of the box fan. The air absorbs in the box fan through heat exchange, and thereafter the air is discharged through an outlet port(32) in front of the box fan. Therefore, the part contacting to the heat transfer belt is cooled. For heating a specific part of the human body, polarity of the power source connected to the thermoelectric module is changed. By interchanging the heat absorption part and the heat emission part of the thermoelectric module, heating is performed.

Description

Personal wearable heating and heating device {A wearable cooling and heating appliance}

The present invention relates to a heating and cooling device, and more particularly, to a personal heating and cooling device that can be worn on the body that the user can be worn on the body to intensively heat the desired area.

In general, the air conditioner is a device for cooling and heating an indoor space such as a residential space, a commercial space, or an office. The construction and operation of such an air conditioner will be described with reference to FIG. 1 of the accompanying drawings.

First, the refrigerant gas compressed by the high temperature and high pressure in the compressor (1) is sent to the first heat exchanger (2), and in the first heat exchanger (2), the outside air blown by the blower fan (3) installed on one side. As a result of the refrigerant gas is liquefied by releasing the heat of condensation condensation occurs.

At this time, the hot air passing through the first heat exchanger 2 is discharged to the outside.

Thus, the refrigerant condensed in the first heat exchanger (2) is passed to the second heat exchanger (5) after being reduced to a pressure that is easily condensed and evaporated while passing through the expansion valve (4), and the second heat exchanger (5) In the refrigerant absorbing the external heat while the refrigerant liquid evaporates by the external air blown by the blowing fan (6) installed on one side.

Accordingly, the cooling air deprived of heat while passing through the second heat exchanger 5 is discharged into the room to cool the room. The evaporated refrigerant is a low-temperature low-pressure gas that is sent to the compressor 1 and The same process is repeated.

On the other hand, if you want to heat the room with the air-conditioning device as described above, the refrigerant may be circulated in reverse. In this case, the second heat exchanger (5) acts as a condenser so that warm air flows into the room. The first heat exchanger 2 acts as an evaporator so that cold air is discharged to the outside.

However, since the conventional conventional air conditioning and heating devices are designed to cool or heat the entire indoor space, the air conditioning effect is not transmitted well in an area far from the air conditioning system, and it is impossible to satisfy all the individual tendencies of everyone in the room. Not only that, there was also an inefficient problem of air conditioning required for heating and cooling.

In other words, physiologically, the human breathing rate is 0.133 ℓ / s per person, but the standard air conditioner supplied by general air-conditioning system is 10 ℓ / s per person, and the actual amount required by humans is about 1% of the total air conditioning amount. It is only known.

In addition, the conventional air-conditioning device as described above is bulky and heavy fixed type to be impossible to carry, in particular, a person must move to another place where the air-conditioning system is not installed outside the room where the air-conditioning system is installed. In this case, there was also a problem that no air conditioning can be expected at all.

Accordingly, an object of the present invention is to provide a personal heating and cooling device that can be used exclusively by a user by allowing a user to wear it on a part of the body.

It provides a personal heating and cooling device that can be worn on the body made of a box fan.

Hereinafter, with reference to the accompanying drawings will be described in detail the air conditioning apparatus of the present invention.

As shown in Figures 2 and 3, the heating and cooling device of the present invention, the thermoelectric module electrically operated on the center of the heat transfer belt 10 made of a long band-shaped flexible member to be worn around the user's body part An upper ceramic plate 21 of 20 is attached, and a box fan 30 through which heat can be transferred from the thermoelectric module 20 to the lower ceramic plate 22 on the opposite side of the thermoelectric module 20. It is made of a structure that is attached.

The heat transfer belt 10 receives heat from the thermoelectric module 20 and transfers the heat back to the user's body. The heat transfer belt 10 may accumulate heat in a flexible metal plate having excellent heat transfer efficiency or therein. The heat storage material may be made of a belt or the like, and may be made of any material capable of receiving heat from the thermoelectric module 20.

In addition, the box fan 30, the rear surface is bonded to one side of the thermoelectric module 20, both sides and the upper and lower surfaces are formed with an inlet 31 through which air is introduced, the air in the front portion In the hollow box-shaped case in which the discharge port 32 is discharged, the blower fan 34 is configured to suck and discharge external air through the inlet port 31.

In addition, a drive motor 33 for driving the blower fan 34 is mounted in the box fan 30.

In addition, the thermoelectric module 20 and the drive motor 33 in the box fan 30 are electrically operated, and the thermoelectric module 20 and the box fan 30 are disposed at predetermined portions of the heat transfer belt 10. The power source 40 connected to the driving motor 33 in the) is detachably mounted, and as a power source 40 for supplying electricity, a rechargeable battery, a vehicle adapter, or a home adapter may be used.

On the other hand, the thermoelectric module 20 is a heat absorbing part to absorb heat from one side according to the electrode connected to it, the other side acts as a heat dissipating part to release the heat absorbed from the heat absorbing portion to the heat transfer belt 10 and the box The heat is transferred to the fan 30. For reference, an operation principle, a configuration, and a characteristic of the thermoelectric module 20 will be described with reference to FIG. 5.

In general, a thermoelectric module is an electrical component based on a semiconductor material that functions as a solid state heat pump. When a current flows in a coupling part connected in series with two different materials, a thermoelectric module emits or absorbs heat at a contact point of two materials. The Peltier Effect is used, and the thermal energy emitted is proportional to the magnitude of the current.

As shown in FIG. 5, the thermoelectric module 20 used in the cooling and heating apparatus of the present invention using this principle includes an upper ceramic plate 21 formed in contact with an object Tc to absorb and cool heat. The lower ceramic plate 22 formed to contact the object Th for dissipating heat and the p-type semiconductors 24 alternately arranged to connect the upper ceramic plate 21 and the lower ceramic plate 22. And electrically connecting the n-type semiconductor 25 and the p-type semiconductor 24 and the n-type semiconductor 25 to both ends of the p-type semiconductor 24 and the n-type semiconductor 25. It consists of an electrical cross-connection layer 23 made of copper or the like serving as a medium for connecting the plate 21 and the lower ceramic plate 22, the cross-connection layer 23 is connected to a direct current power source (P) The current flows through the p-type semiconductor 24 and the n-type semiconductor 25.

Therefore, when the user applies power to cool or heat the object Tc by using the thermoelectric module 20 configured as described above, the current i is connected to the n-type semiconductor 25 by the cross connection layer 23. ) And p-type semiconductor 24 alternately flow, whereby electron (-) moves in the direction opposite to the direction of current (i) in n-type semiconductor (25), while in p-type semiconductor (24) The hole (+) moves in the flow direction of.

That is, the electron (-) and the hole (+) are respectively moved from the upper ceramic plate 21 to the lower ceramic plate 22 through the n-type semiconductor 25 and the p-type semiconductor 24, thereby Since the ceramic plate 21 absorbs heat and releases it to the lower ceramic plate 22, the upper ceramic plate 21 acts as a heat absorbing portion, and the object Tc in contact with the upper ceramic plate 21 is cooled. The lower ceramic plate 22 serves as a heat dissipation unit so that the object Th in contact with the lower ceramic plate 22 is heated.

In addition, when the polarity of the electricity connected to the thermoelectric module 20 is changed to change the direction of the current, that is, if the parts connected to the positive electrode (+) and the negative electrode (-) of the power supply P are interchanged with each other, the phenomenon described above. On the contrary, heat is released from the lower ceramic plate 22 toward the upper ceramic plate 21 so that the heat absorbing part and the heat radiating part are switched, and the magnitude of the heat energy absorbed and radiated can be changed by changing the magnitude of the supplied current. Will be understandable.

On the other hand, the thermoelectric module has the following characteristics.

First, accurate temperature control is possible because the magnitude of heat energy absorbed and dissipated is proportional to the amount of current supplied.

Second, there is no noise and vibration because it does not use mechanical elements that cause movement.

Third, it is compact and light.

Fourth, local air-conditioning is possible.

Fifthly, it is environmentally friendly since no CFC gas or any refrigerant is used.

Sixth, heating and cooling are determined according to the current direction.

Accordingly, the upper ceramic plate 21 of the thermoelectric module 20 attached to the heat transfer belt 10 becomes a heat absorbing portion to absorb heat from the heat transfer belt 10 to cool the heat transfer belt 10 and at the same time, The lower ceramic plate 22 on the opposite side of the thermoelectric module 20 serves as a heat dissipation unit to dissipate heat to the box fan 30.

At this time, the outside air is introduced through the inlet 31 of the box fan 30 by the operation of the blower fan 34 in the box fan 30, and the air introduced in this way is in the box fan 30. After the heat exchange in the absorbing heat, it is discharged through the outlet 32 in front of the box fan 30.

Therefore, the body part wound the heat transfer belt 10 is cooled, and the hot air is released to the opposite side to the user to be able to perform the cooling operation for the individual.

On the other hand, when the heating is to be operated in winter, the user is switched to the polarity of the power source connected to the thermoelectric module 20 by switching the heat absorbing portion and the heat dissipation portion of the thermoelectric module 20, accordingly to the opposite to the cooling operation Heating operation is performed.

In other words, when the electrode connected to the thermoelectric module 20 is switched, the upper ceramic plate 21 of the thermoelectric belt 10 and the grounded thermoelectric module 20 becomes a heat dissipation unit, and the lower ceramic plate 22 of the opposite side is The heat absorbing part absorbs heat from the air introduced through the box fan 30, and heats the heat transfer belt 10 by releasing heat from the upper ceramic plate 21 serving as the heat radiating part.

In addition, the air conditioning apparatus of the present invention can be used without sensing around the body, that is, the user places the air conditioning apparatus on a desk and the like by using the cold or warm air discharged through the box fan 30 around the individual. It can also be heated intensively.

On the other hand, the present invention is not limited to the above-described embodiment, and various changes and implementations can be made without departing from the gist of the present invention.

For example, the box fan 30 is used as a heat exchange member positioned on the opposite side of the heat transfer belt 10 to release or absorb heat, but instead of the box fan 30, a metal plate capable of simply receiving heat is provided. It may be attached.

In addition, the air-conditioning device of the present invention has a function of intensively heating and cooling the body part, it can also be applied to the medical device for cold and hot pack.

As described above, according to the present invention, it is possible to intensively heat and heat a desired area by winding the user's body, so that the user can be satisfied individually, and can be easily used in any place of indoor and outdoor. Done.
