  By the way, when this inventor advanced research about this conventional air-conditioning chair, in this conventional air-conditioning chair, since conditioned air only passes upwards through the back part, it is enough to warm a foot at the time of heating. No, therefore, it turned out that it was difficult to fully enhance the comfort of the seated person. In order to solve this problem, simply providing air-conditioning air outlets at the feet reduces the amount of air-conditioning air that passes upwards through the back during cooling, and therefore also provides sufficient comfort for the seated person. It turned out to be difficult to increase.

  Therefore, an object of the present invention is to provide an air-conditioning chair that can sufficiently improve the comfort of a seated person and can improve the air-conditioning efficiency both during cooling and during heating.

  An air-conditioning chair according to the present invention that advantageously solves the above problems comprises a leg portion, a back portion and a seat portion supported by the leg portion, and conditioned air supplied from an conditioned air supply path is vertically moved in the back portion. An air conditioning chair that blows upward and obliquely rearward from an air conditioning air passage extending in a direction, and an intermediate box that is located below the back portion and the seat portion and communicates with the air conditioning air supply passage and the air conditioning air passage in the back portion; An opening / closing member that opens and closes the conditioned air passage in the back portion, an auxiliary air passage that communicates with a connecting portion between the intermediate box and the conditioned air passage in the back portion and opens forward toward the lower portion of the seat portion, It is characterized by comprising.

  In such an air-conditioning chair, at the time of cooling, for example, by opening an opening / closing member that opens and closes the conditioned air passage in the back, the conditioned air supplied from the conditioned air supply path is vertically moved in the back via the intermediate box Is supplied to the conditioned air passage extending from the air conditioned air passage, and is blown obliquely upward and backward from the conditioned air passage. Further, the conditioned air communicates with a connection portion between the intermediate box and the conditioned air passage in the back portion of the seat portion. The air below the seat is attracted from the auxiliary air passage that opens downward and forwards, and is blown obliquely upward and rearward of the back together with the air-conditioned air, increasing the amount of air blown out and improving the air-conditioning efficiency.

  On the other hand, at the time of heating, for example, by closing an opening / closing member that opens and closes the conditioned air passage at the back, the conditioned air supplied from the conditioned air supply passage is passed through the intermediate box through the intermediate box and the conditioned air passage in the back The air is blown down from the auxiliary air passage that communicates with the connecting portion and opens forwardly toward the lower portion of the seat portion.

  The amount of conditioned air blown upward from the back conditioned air passage and the conditioned air blown downward from the auxiliary air passage to the lower portion of the seat by appropriately adjusting the opening of the opening and closing member as necessary during cooling and heating. The ratio with the amount can be changed.

  Therefore, according to the air-conditioning chair of the present invention, the comfort of the seated person can be sufficiently improved both during cooling and during heating, and the air-conditioning efficiency can be increased.

  In the air-conditioning chair according to the present invention, it is preferable that the opening / closing member is disposed at the lower end portion of the back portion so as to be opened and closed from the front side.

  Since the opening / closing member opens and closes the conditioned air passage at a position close to the connection portion between the intermediate box and the conditioned air passage in the back portion, the conditioned air is sent from the intermediate box to the auxiliary air passage communicating with the connection portion at a short distance. Since it is supplied and blown out below the seat without causing much temperature change, the air conditioning efficiency can be increased, and the opening / closing member has a simple structure that can be opened and closed, so that it is inexpensive. The air conditioning function of the air conditioning chair can be enhanced.

  In the air conditioning chair according to the present invention, it is preferable that the intermediate box has an air outlet that can be opened and closed and opens forward facing the seat portion. In this way, by operating and opening the outlet during heating, a large amount of warm conditioned air can be supplied to the lower part of the seat portion, and the comfort of the seated person can be further improved.

  Furthermore, in the air-conditioning chair according to the present invention, the intermediate box communicates with a plurality of the air-conditioning chairs connected in the left-right direction, and conditioned air supplied from the conditioned air supply path is provided in the intermediate box. It is preferable that a rectifying plate for horizontally dispersing is provided. In this way, even when the number of conditioned air supply paths is smaller than the number of conditioned chairs, the conditioned air can be dispersed to sufficiently improve the comfort of many seated persons.
