The thermoelectric element 10 is configured to generate cold air or warmth by using a thermoelectric phenomenon.

The thermoelectric element 10 is an energy source that operates when receiving power to generate a thermoelectric phenomenon, and the thermoelectric phenomenon refers to the Peltier effect.

The Peltier effect is an effect in which an energy source generated by power generation simultaneously generates cooling and heating, and the thermoelectric phenomenon in the thermoelectric element 10 is a well-known technique widely known to those skilled in the art to which the present invention pertains. Therefore, detailed description will be omitted.

The surface of the thermoelectric element 10 generating cold air or heat may be changed according to the direction of power input. Therefore, only the direction of the power input can be easily switched through the control board when cold air is needed and when warm air is needed.

The heat pipe 21 and the heat dissipation fin 22 may be applied in plurality to improve the heat dissipation effect.

For example, as shown in FIG. 1 , a plurality of heat dissipation fins 22 may be disposed at regular intervals in the upper and lower directions, and the heat pipe 21 is a plurality of heat dissipation fins 22 , in a state in which the plurality of heat dissipation fins 22 are disposed at regular intervals. and one end may be in contact with the thermoelectric element 10 .

In addition, heat may be radiated through the radiating fins 22 and the heat pipe 21 in order to radiate the heat of the surface where the heat is generated.

In order to maximize the effect of heat dissipation, a fan 50 may be disposed on one side and the other side of the heat dissipation fins 22 , respectively.

The fan 50 disposed on the left side with reference to FIG. 1 sucks outside air. And, the fan 50 located on the right exhausts the air.

That is, the outside air sucked by the fan 50 located on the left passes through the space between the heat dissipation fins 22 and then is exhausted by the fan 50 located on the right side, and the outside air passes through the space between the heat dissipation fins 22 . The heat dissipation fin 22 is cooled while passing.

Although not shown in the drawings, in order to maximize the effect of heat dissipation, the fan 50 may also be disposed on the upper and lower surfaces of the heat dissipation fins 22 and the right and left sides of the heat dissipation fin 22 to introduce outside air.

The UV-C LED 40 is disposed on one side of the heat sink 30 , and irradiates the heat sink 30 with UV-C light for sterilization.

That is, when cold energy is transmitted to the heat sinks 30 , moisture is generated on the surface due to a temperature difference with the outside air, which forms an environment in which pathogens such as bacteria can inhabit. Therefore, it is possible to prevent the activation of pathogens by irradiating the light source of the UV-C LED 40 so as not to generate bacteria on the heat sinks 30 .

The cover unit 60 includes the thermoelectric element 10 described above, the heat dissipation unit 20 , the heat dissipation plate 30 , and the first cover unit 61 accommodating the UV-C LED 40 and the fan 50 . and a second cover unit 62 .

On the other hand, the blow fan 70 is disposed on the other side of the heat sink (30). The blow fan 70 faces the UV-C LED 40 with the heat sinks 30 interposed therebetween.

The blow fan 70 is located in the space between the heat dissipation fins 22 through air intake and sucks air sterilized by the UV-C LED 40 and raises it.

The transfer pipe 80 is disposed above the blow fan 70 . The transfer pipe 80 has an open upper surface and a lower surface, and a transfer passage is formed therein.

Therefore, the sterilized air sucked by the blow fan 70 is raised through the transfer passage.

The transfer pipe 80 may be accommodated in the inner space of the intermediate cover 63 provided on the upper side of the second cover unit 62 .

A discharge pipe 81 is formed on the upper surface of the transfer pipe 80 . The discharge pipe 81 has an open bottom surface facing the top surface of the transfer pipe 80 .

For example, the left side and the right side of the discharge pipe 81 are also opened, and the right side can be closed by the stopper (4).

As another example, only the left side of the discharge pipe 81 may be opened.

Accordingly, the sterilized air that has been raised through the transfer passage is discharged to the outside through the discharge pipe 81 .

In order to transfer the air sucked from the blow fan 70 to the exhaust pipe 81 without energy loss, the material of the transfer pipe 80 may be formed of a material such as copper or engineering plastics. .

The photocatalytic filter 90 and the UV-A LED 100 are disposed in the inner space of the discharge pipe 81 .

By sterilizing the air sterilized by the UV-A LED 100 through the photocatalytic filter 90 and the UV-A LED 100 once more, cleaner air can be emitted.

The discharge unit 110 discharges the sterilized air in the discharge pipe 81 to the outside, and is located on the upper portion of the intermediate cover 63 of the blowing fan 111 and the second cover unit 62 accommodated in the protection net 1 . It may include a blower motor 112 accommodated inside the located rear cover and rotating the blower fan 111 in place.

The blower motor 112 is accommodated in the rear cover 3 formed on the upper side of the intermediate cover 63 .

It is possible to maximize the role of the heat radiation fin 22 and the heat pipe 21 by rapidly discharging the air staying in the heat radiation fin 22 to the outside through the heat radiation fin 22 .

In this case, the material of the heat sink 30 and the heat radiation fin 22 connected to the thermoelectric element 10 is not particularly limited. However, it should be made of a material that can support the thermal conductivity and strength that can increase the reliability of the thermoelectric element 10 . In addition, the material of the heat pipe 21 connected to the heat dissipation fin 22 is preferably made of a copper (Copper) material having high thermal conductivity, and may be changed to an aluminum alloy material if necessary.

The sterilization time of the UV-C LED 40 should be continuously operated while the blowing fan 111 and the thermoelectric element 10 are operating. In addition, even when the blowing fan 111 and the thermoelectric element 10 stop operating, moisture remains in the heat sink 30 to become an environment in which bacteria can be activated.

Therefore, it must be programmed so that the operation of the UV-C LED 40 is maintained for a certain period of time even if the operation is stopped. The holding time may be set in mW, which is the Radiant Flux Power of the UV-C LED 40 . For example, it can be set to maintain 5 minutes in the case of 3mW of the UV-C LED 40, and maintain 10 seconds in the case of 100mW of the UV-C LED 40.

The UV-A LED 100 and the photocatalytic filter 90 are structures for air sterilization, and the photocatalytic filter 90 must be used together with the UV-A LED 100 to activate the photocatalytic reaction to generate a deodorizing effect. do. In addition, the wavelength of the UV-A LED 100 should use a product in the wavelength range of 315 ~ 400nm.
