  In the case of an air-conditioning chair in which the chamber and the air passage are provided inside the back plate (back portion), the back plate is thickened by the thickness of the chamber and the air passage. As a result, since the back plate needs to have a sufficient thickness, the degree of freedom in design is low, and the appearance is deteriorated. For example, it is difficult to manufacture a curved back plate.

  In addition, when air is blown out from the air outlet formed on the rear side of the back plate, the air directly hits the user of the rear air conditioning chair, and the user feels uncomfortable.

  In order to solve the above problems, an air conditioning chair according to the present invention is an air conditioning chair that blows out supplied air, and includes a seat and a back plate, and an armrest provided with a first duct through which the air flows, The rear part of the armrest protrudes rearward from at least a part of the back plate, and the rear part of the armrest is provided with an air outlet that faces the back plate and communicates with the first duct, A louver assembly that guides the air upward is disposed at the outlet.

  Moreover, the air conditioning system of this invention is provided with the said air conditioning chair, the air conditioning apparatus which supplies air to the said air conditioning chair, and the air supply duct connected to the said air conditioning apparatus and the said air conditioning chair.

  According to this invention, the blower outlet for blowing off air is provided in the rear part of the armrest which protruded back rather than the backplate. This eliminates the need to form an air outlet or duct on the back plate. Therefore, an air conditioning chair with a high degree of design freedom can be provided.

  Moreover, in this invention, the blower outlet is facing the back board, and the air supplied from the outside is guide | induced to the upper direction of an air-conditioning chair by the louver assembly. Therefore, the blown air flows upward along the rear surface of the back plate, and the space where the user of the rear air conditioning chair is present can be efficiently air-conditioned. Furthermore, air can be prevented from directly hitting the user of the rear air conditioning chair.

That is, the air outlet 21 is provided on the upper side surface of the rear assembly 22 so as to face the curved surface 120 of the back plate 12.

  Thus, in this invention, the blower outlet 21 and the duct are not provided in the backplate 12. FIG. Therefore, the freedom degree of design of the back board 12 can be raised. For example, the back plate 12 of the present embodiment has a curved surface 120 in order to improve the aesthetic appearance. Further, the rear assembly 22 protrudes rearward from a part of the back plate 12 so that the air outlet 21 on the side surface of the armrest 2 faces the rear surface of the back plate 12. Therefore, as shown by an arrow in FIG. 3, the air blown toward the back plate 12 side is guided upward by the louver assembly 4 disposed at the blower outlet 21. Thereby, as shown by the arrow in FIG. 1, the air flows along the back plate 12 to the upper side of the air conditioning chair 1, and the space where the user of the rear air conditioning chair 1 is present is efficiently air-conditioned. Furthermore, since the air is not directly applied to the user of the air conditioning chair 1 on the rear side, the user's discomfort can be reduced.

  Further, the back plate 12 of this embodiment has a curved surface 120. The rear assembly 22 is located behind the side end portion 122 at a substantially central portion in the height direction of the back plate 12. Therefore, the blower outlet 21 is located in front of the most protruding part of the back plate 12. As a result, the rear assembly 22 does not protrude greatly with respect to the back plate 12. Therefore, it can prevent that the size of the air-conditioning chair 1 becomes large. Moreover, if the blower outlet 21 is opened upward, dust may enter the vertical duct 31. On the other hand, the blower outlet 21 of a present Example is opened toward the side. Therefore, intrusion of dust into the vertical duct 31 is prevented.
