【Example】

 Embodiments of the present invention will be described below with reference to the drawings. 1 is a side view showing an installation state of a concealed fan coil unit, FIG. 2 is an enlarged vertical sectional view of a portion A in FIG. 1, and FIG. 3 is a perspective view showing an embodiment of the present invention. FIG. 4 is a plan view showing one usage state of the present embodiment, and FIG. 5 is an enlarged view of a portion B in FIG.

When the fan coil unit is concealed, the fan coil unit main body 3 is installed on the floor surface 2 inside the window stand 1 as shown in FIG. 1, for example. This figure shows a state in which the side panel of the window stand 1 is removed. Then, the regulated air from the fan coil unit body 3 is introduced into the room through the external air outlet 4 provided on the upper surface of the window stand 1. The duct in the present invention corresponds to the duct 5 for connecting the external outlet 4 and the internal outlet 3a opened in the fan coil unit body 3.

A rectangular opening is formed in the center of the upper surface of the steel plate housing of the fan coil unit body 3, and this opening forms the internal air outlet 3a of the present invention. Then, the steel plate forming the connecting portion 3b for actually connecting the duct 5 is erected from each of the four sides of the rectangular opening. Further, by fitting an outer cover 6 made of a steel plate having a shape as shown in FIG. 2 into the opening 1a on the upper surface of the window stand 1, the outer outlet 4 facing the room is formed. The outer cover 6 has a base portion 6a on which an attachment 7 for determining the direction of the blown airflow is placed, and a connecting portion 6b for actually connecting the duct 5, and the lower end opening formed by the connecting portion 6b. The size of 6c is smaller than the size of the external air outlet 4. Here, the shape and dimensions of the lower end opening 6c are formed to be the same as the internal air outlet 3a of the fan coil unit body 3 described above.

Therefore, in this example, the edges 5 a and 5 b of the duct 5 are connected to the connecting portion 3 b that surrounds the inner outlet 3 a of the fan coil unit body 3 and the connecting portion 6 b that forms the lower end opening 6 c of the outer cover 6. By externally fitting, the internal air outlet 3a opened in the fan coil unit body 3 and the external air outlet 4 provided facing the room are connected.

In the present invention, the duct 5 is made of a heat insulating sheet. As the heat insulating sheet, for example, one used in a simple cooler box or the like is used. This is the formation of innumerable closed cells in soft plastic. Then, the cross-sectional shape of each edge of the duct 5 is made to correspond to the shape of the lower end opening 6c of the outer cover 6 and the inner air outlet 3a of the fan coil unit body 3, and the length is set to the lower end opening 6c. And the vertical dimension of the internal air outlet 3a. In this example, since the lower end opening 6c is formed in a rectangular shape having the same size as the internal air outlet 3a, the duct 5 has a rectangular cross section. This tubular body is manufactured, for example, by bending one sheet of the heat insulating sheet so as to correspond to the rectangle, and stitching or bonding the ends thereof.

Further, in the present invention, fine granular magnets are dispersed in the rubber around the entire inner surface of the edge 5a on the inner outlet 3a side and the edge 5b on the outer outlet 4 side of the duct 5 so as to have a thickness. Magnetic tapes 8a and 8b formed into a tape shape having a width of about 1.5 mm and a width of about 10 mm are fixed by an adhesive. Therefore, the fan coil unit main body 3 is installed at a predetermined position inside the window stand 1 corresponding to the lower part of the opening 1a, and the duct 5 is fitted to the connecting portion 3b extending from the upper surface of the housing at one edge 5a thereof. Then, the magnetic tape 8a is brought into close contact with the outer periphery of the connecting portion 3b made of a steel plate, and the duct 5 extends above the internal outlet 3a. Then, the outer cover 6 is fitted into the opening 1a of the window stand so that the outer surface of the connecting portion 6b contacts the inner surface of the other edge 5b of the duct 5, and the magnetic tape 8b fixed to the inner surface of the duct 5 is attached to the steel plate. It is closely attached to the connection part 6b.

In this way, the internal outlet 3a opened in the fan coil unit body 3 and the external outlet 4 provided facing the room are easily connected. On the other hand, as shown in FIG. 3, this duct 5 has a cross-section of one type of duct 5 if the magnet tape 8 fixed to the inner surfaces of both edges has a notch 9 extending in the longitudinal direction of the duct 5. It can also be used for many types of outlets that have the same shape and small dimensions.

In the duct 5 shown in FIG. 3, a plurality of cuts 9 are made at intervals of 10 mm in the vicinity of the center of the long side of the rectangle forming the cross section and the entire short side. When the magnet tape 8 is fixed to the inner surface of the duct 5, the notch 9 is fixed to the portion where the notch 9 is to be formed by cutting the magnet tape previously cut to a length of 10 mm with an interval corresponding to the notch width. It is formed by doing. Further, a pair of velcro tapes 10a and 10b are fixed by an adhesive on both sides of the plurality of notches 9 centering on the extension lines of the notches 9a at the centers of the long sides and the short sides. There is.

As a result, when the dimensions of the long side and the short side of the rectangle forming the cross section of the duct 5 are larger than the outer dimensions of the connecting portions 3b and 6b for connecting the respective edges 5a and 5b of the duct 5, The size of the duct 5 can be adapted as follows. For example, when the dimension of the long side is large, the duct 5 is bent by pinching the duct 5 from the outside with a finger in the vicinity of the notch 9a at the center of each side, and the magnetic tapes 8 are magnetically fixed to each other so that the duct 5 has an extra dimension. To the outside, and as shown in FIG. 4, the length L of the long side is adjusted to the corresponding dimension of 3b and 6b of each of the connecting portions. Do the same when the short side is large. At this time, since the portion B showing the vicinity of the portion to be cut out is as shown in FIG. 5, the width of the notch 9 is set to a size that can be handled in this way.

Further, in this example, since the magic tapes 10a and 10b are provided as described above, the ducts 5 are not overlapped even between the magnet tapes 8 on both edges by sticking the magic tapes 10a and 10b together. It is possible to extract a portion having different dimensions to the outside, and to arrange the shape of the duct 5 in the longitudinal direction.
