The cup holder can be refrigerated or warmed at the same time.

The circulation flow path for refrigerating or warming the cup holder will be described together with the cold / cold method of the cup holder device of the present invention.

The cold / cold method of the cup holder apparatus of this invention.

Applying a refrigerated or warmed signal to the thermoelectric element;

Transmitting a cold source or a heat source supplied to the upper surface of the thermoelectric element 28 according to the signal applied to the thermoelectric element 28 to the cold hot plate 12 in contact with the upper surface of the thermoelectric element 28;

Moving the air inside the main body part 2 downwardly to the cold plate 12 by the operation of the air conditioning fan 10;

The air refrigerated or warmed by the cold plate 12 moves along the flow path guide 18 to move to the air conditioning unit 4 on both sides through the discharge hole 8 at the bottom of the blocking wall 6. step;

And refrigeration or warming the cup while the air moved to the air conditioner 4 exchanges heat with the cup seated in the air conditioner 4.

After refrigeration or warming the cup,

The rising air flow in the air and the step of moving the air along the rising air flow to the suction port 24 by the air conditioning fan 10 proceeds sequentially, and then the air conditioning fan 10 As a result, the air moves to the cold plate 12.

That is, a cold or heat source supplied to the upper surface of the thermoelectric element 28 according to the step of applying a refrigeration or heating signal to the thermoelectric element 28 and the signal applied to the thermoelectric element 28 is the thermoelectric element ( Steps except for the step of being delivered to the cold plate 12 in contact with the upper surface of the 28 is repeated to refrigerate or warm the cup seated on the air conditioner (4).

First, a method of refrigerating the cup holder will be described.

First, when a refrigeration signal is applied to the thermoelectric element 28, a cold source is supplied to the upper surface of the thermoelectric element 28, and a heat source is supplied to the lower surface of the thermoelectric element 28.

The cold source of the upper surface of the thermoelectric element 28 is transmitted to the cold plate 12 in contact with the upper surface of the thermoelectric element 28 to cool the cold plate 12, and at the same time the heat source of the lower surface of the thermoelectric element 28 The heat transfer plate 30 is brought into contact with the bottom surface of the thermoelectric element 28 to heat the heat sink 30.

By operating the air conditioning fan 10, the air inside the main body 2 is moved downwardly to the cold plate 12, and the air is cooled while exchanging heat with the cold plate 12.

The air cooled by the cold plate 12 moves along the flow guide 18 and moves to both air conditioning units 4 through the discharge holes 8. At this time, the flow rate of the air moving to each of the air conditioning unit 4 is the same.

The air moved to the air conditioning unit 4 hits the cup seated in the air conditioning unit 4 to cause turbulence, and the cup is refrigerated while heat-exchanging with the cup.

The remaining air which is not heat-exchanged with the cup among the air discharged to the air conditioner 4 moves in both directions between the cup and the inner wall of the air conditioner 4. In the process, air moving in different directions collide with each other, or the air collides with the inner wall of the air conditioning unit 4 to generate turbulence, thereby generating an updraft.

Therefore, the upward airflow forms the circulation flow path of the air. The circulation flow path includes an up-down circulation flow path in the body portion in which the air circulates through the air conditioning fan 10 and the cold / hot plate 12 in sequence, and The air flows into the air conditioning unit 4 along the flow guide 18 of the hot and cold plate 12 includes a circumferential circulation flow passage circulating along the circumference of the cup.

The air moved along the upward airflow is sucked into the suction port 24 by the operation of the air conditioning fan 10, and the air sucked into the suction port 24 is operated by the operation of the air conditioning fan 10. It moves downward to the cold plate 12.

Thereafter, a cooling or heating signal is applied to the thermoelectric element 28, and a cold source or a heat source supplied to the upper surface of the thermoelectric element 28 according to the signal applied to the thermoelectric element is an upper surface of the thermoelectric element 28. The remaining steps are repeated except for the step of being delivered to the cold plate 12 in contact with the cold plate 12 to refrigerate the cup seated on the air conditioner 4.

As the above steps are repeated, the cooling performance increases.

When the cold plate 12 is cooled by the thermoelectric element 28 and the heat sink 30 is heated at the same time, the heat radiating fan 34 is operated to draw outside air of a relatively low temperature inside the heat radiating portion 26. It will flow into.

The air introduced into the heat dissipation unit 26 by the heat dissipation fan 34 moves toward the heat dissipation plate 30 to lower the temperature of the heat dissipation plate 30 heated by the thermoelectric element 28.

The air heated through heat exchange with the heat sink 30 is discharged to the outside of the heat radiator 26.

A method of warming the cup holder according to the above steps will be described.

First, when a warm field signal is applied to the thermoelectric element 28, a heat source is supplied to an upper surface of the thermoelectric element 28, and a cold source is supplied to a lower surface of the thermoelectric element 28.

The heat source on the upper surface of the thermoelectric element 28 is transferred to the cold plate which is in contact with the upper surface of the thermoelectric element 28 to heat the cold plate 12, and at the same time the cold source of the lower surface of the thermoelectric element 28 is the thermoelectric element The heat sink 30 is in contact with the bottom surface of the 28 to cool the heat sink 30.

By operating the air conditioning fan 10, the air inside the main body 2 is moved downwardly to the cold plate 12, and the air is heated while exchanging heat with the cold plate 12.

The air is then circulated in the same way as the refrigeration to heat the cup.
