In addition, the bottom surface 1430 of the slide cap 1400 extends inward to form a stepped space. Depending on whether the bottom surface 1430 of the slide cap 1400 is engaged with the stepped bottom surface of the slide cap and the engagement protrusion 1220 of the insertion member, Cooling air or warm air supplied into the supporting pillars 1210 of the sliding member from the sliding door 130 through the elongated hole 1211 of the support can be discharged or cut off to the through hole 1410 of the slide cap.

In particular, the slide cap 1400 is formed with a stepped bottom surface 1430 having a thickness of at least an enlarged size relative to the long hole so as to cover the elongated holes 1211 of the column, As the slide cap is downward with the contraction of the elastic member, the long hole, which is blocked by the bottom surface of the slide cap, is opened And the cooling air or the hot air, which is poured on the inside of the column, can be discharged to the through hole (1410) of the slide cap.

6 to 8, exhaust paths of cold air and hot air are shown in detail with respect to the above structure.

The cold / warm unit 1000 of the present invention is positioned in a state as shown in FIG. 6 when the first occupant is absent. The cold / hot unit of the present invention protrudes from the seat portion 110 and the back hole 120, And this protruding arrangement is not only made possible by the elastic member 1300 lifting the slide cap 1400 but also allowing the slide cap bottom 1430 to naturally overlap with the long hole 1211 of the support 1210 Lt; / RTI > That is, the cold air or the warm air passed through the supply pipe can not escape into the long hole blocked through the bottom surface of the slide cap as well as the upper surface of the support. The related diagram is shown in Fig.

When the user sits on the backrest 120 and the seat part 110 in the above-described state, the cold / warm unit 1000 is pressed in a specific direction as shown in FIG. 7, A flow of warm air can be made possible. That is, the slide cap 1400 supported by the elastic member 1300 is downwardly depressed due to the pressure of the seated person passing through the pressing protrusion 1420. At this time, the slide cap is downward by a certain distance, So that the cold air or the warm air that has been blocked through the bottom surface 1430 of the slide cap is discharged from the inside of the column to the outside through the through hole 1410 of the slide cap.

Such a structure allows the seated person to selectively discharge cold air or hot air as well as an effect of acupressure, so that cold air or hot air is not discharged to the cold / warm unit in the area where the occupant does not reach, .

As described above, according to the present invention, since the related structure of the cold / warm sheet can be selectively supplied with cool air and warm air unlike the normal structure, the cooling and heating functions can be easily implemented with only one sheet Of course, there is an effect that the energy consumption is small, the noise and the breakdown are small, maintenance is easy, and it can be positively protected from safety accidents such as electric shock. Particularly, it is possible to provide several acupressure / heating units to a seated user with an acupressure effect. In particular, the internal structure in which cold air and warm air are supplied can firmly support the weight of the user, So that the energy efficiency can be maximized.
