The communication pipe 23 is provided with a fixing screw 25, a fixing tool 26, and a fixing rib 27, and the rotational movement of the fixing tool 26 generated by tightening the fixing screw 25 is a descending movement due to the blocking of the fixing rib 27. Instead, the communication pipe 23 is fixed to the installation surface by sandwiching the installation surface with the communication pipe end portion 28 forming the indoor side opening 22 and the fixture 26. Further, by fitting the connecting flange 29 provided in the communication pipe end portion 28 and having a concave portion with the connecting claw portion 31 provided on the panel inner surface 30 facing the indoor opening 22 of the panel 24, The communication pipe 23 and the panel 24 are connected. Since the connection flange 29 and the connection claw portion 31 are all present on the same circumference in plan view, the installation direction of the panel 24 with respect to the communication pipe 23 in plan view can be changed. The fresh air introduced from the communication pipe 23 is supplied into the room through the blowout opening 32 formed by the communication pipe end portion 28 and the panel inner surface 30. Since the communication pipe end portion 28 and the panel inner surface 30 have a certain angle of 0 ° or more and 45 ° or less with respect to the ceiling surface, the communication tube end portion 28 and the panel inner surface 30 in the vicinity of the blowout opening 32 are arranged. The central axis has a previous angle with respect to the ceiling surface. The central axis of the pipe means a line connecting the centers of all cross sections when the pipe is a circular pipe, and a line connecting the intersections of diagonal lines in all cross sections when the pipe is a square pipe. . Moreover, when the blower opening which the blower opening 32 is open in many directions or a fan shape is used, the said fresh air can be blown out in a multidirectional or fan shape. There are several types of panels 24, and the heights of the connecting claws 31 are different from each other. By replacing the panel 24, the opening area of the blowout opening 32 can be changed.

  As a structure of the air outlet 1 other than the above, as shown in FIG. 4, a communication pipe 35 provided with an outdoor side opening 33 for introducing fresh air from an indoor introduction pipe and an indoor side opening 34 for supplying the fresh air toward the room. And a louver 36 connected to the communication pipe 35 at a position facing the indoor opening 34. As in the air outlet shown in FIG. 3, the communication pipe 35 is fixed to the ceiling surface by the fixing screw 37, the fixture 38, the fixing rib 39, and the communication pipe end 40, and is connected to the communication pipe end 40. The communication pipe 35 and the louver 36 are connected by the connection claw portion 42 provided on the flange 41 and the louver 36, and the installation direction of the louver 36 with respect to the communication pipe 35 in a plan view can be changed. The louver 36 is fixed to the blowout opening 43 through which fresh air carried in from the indoor opening 34 is blown into the living room with a fixed angle 45 with a fixed angle 45 with respect to the ceiling surface. In the case of using the one arranged in one direction in a plan view as shown in FIG. 5, the fresh air can be blown out in one direction, and the plane as shown in FIG. When using what is arranged in two directions visually, the fresh air can be blown out in two directions. Several types of louvers 36 having different opening areas of the blowout openings 43 are prepared.

  The ventilation unit 101 is installed on the floor of the non-room 110 for each floor, the air outlet 1 is provided on the ceiling of the room 109, the suction port 105 is provided on the ceiling of the non-room 110, and the outside and the ventilation unit 101 are outdoors. The introduction pipe 106 and the outdoor discharge pipe 107 communicate with each other, the ventilation unit 101 and the outlet 1 communicate with each other through the indoor introduction pipe 102, and the ventilation unit 101 and the suction port 105 communicate with each other through the indoor discharge pipe 104. A door undercut 108 is provided as an air circulation means between each room 109 and the non-room 110. And the blower outlet 1 is provided in the ceiling near the wall surface in the living room 109 closest to the ventilation unit 101, or in the ceiling near the air circulation means 8 in plan view, and fresh air introduced from the indoor introduction pipe 102 is underexposed in plan view. The connection direction of the panel 24 or the louver 36 is set so as to blow off the wall surface farthest from the cut 108 or the corner farthest from the undercut 108. In addition, a living room shows the room where people live, such as a living room and a Japanese-style room, and a non-living room shows rooms, such as a corridor and a washroom. Moreover, although the undercut of a door is used as an air circulation means, the same effect can be acquired also when using the ventilation hole installed on a ventilation gallery, a door, or an air blower.

  According to the above configuration, fresh outdoor air is introduced into the ventilation unit 101 via the outdoor introduction pipe 106 and supplied to the living room 109 from the outlet 1 via the indoor introduction pipe 102. Also, the contaminated air in the living room 109 is discharged to the non-living room 110 by the undercut 108, introduced into the ventilation unit 101 from the suction port 105 through the indoor discharge pipe 104, and discharged to the outside through the outdoor exhaust pipe 7. Is done.

  And when installing the blower outlet 1 on the ceiling near the wall surface closest to the ventilation unit 101, since the ventilation unit 101 is usually provided in the building, the blower outlet 1 is provided on the ceiling near the inner wall. In the winter, it is possible to prevent the fresh air from being cooled by the outer peripheral edge, and it is possible to prevent a resident from being drafted. Further, since the distance between the ventilation unit 101 and the outlet 1 is shorter than that of the conventional ventilation system, the installation length of the indoor introduction pipe 102 can be shortened, and the material cost and the construction cost of the indoor introduction pipe 102 are reduced. be able to. In addition, the pressure loss can be reduced by shortening the installation length of the indoor introduction pipe 102. As a result, the amount of energy consumption can be reduced, and the initial cost for the ventilation unit 101 is sufficient because a low-capacity ventilation unit is sufficient. Can be reduced. In addition, since the installation length of the indoor introduction pipe is short, the probability of sudden bending of the indoor introduction pipe is small, and as a result, the designed air volume can be supplied. Although the air outlet 1 is provided near the wall surface, the air outlet 1 is provided on the ceiling surface of the living room closest to the ventilation unit 101 in consideration of the purpose of shortening the installation length of the indoor introduction pipe 102. Although it is desirable, depending on the installation direction of the building material and the ventilation unit 101, the indoor introduction pipe 102 may be bent sharply, resulting in a high pressure loss. Further, the ventilation unit 101 and the indoor introduction pipe 102 or the indoor introduction pipe 102 and the outlet 1 There is a possibility that the connection part of will be disconnected. Therefore, it is desirable to provide it on the ceiling surface close to the ventilation unit 101 within a range that does not cause a sharp bend in the indoor introduction pipe.

  Further, when the fresh air supplied from the outlet 1 is blown toward the wall farthest from the undercut 108, the fresh air is discharged from the undercut 108 to the non-living room 110 after reaching the wall surface. The effect of ventilation can be sufficiently obtained without causing stagnation on the wall surface. Further, when the fresh air supplied from the outlet 1 is blown toward the corner farthest from the undercut 108, the fresh air reaches the corner and then forms two corners on the wall. Since they are dispersed in the direction, a sufficient ventilation effect can be obtained without causing stagnation in the corners and the wall surface.

  Further, when the air outlet 1 is installed on the ceiling near the undercut 108 in plan view, the undercut 108 and the undercut are compared with the case where the air outlet 1 is installed on the ceiling near the wall surface closest to the ventilation unit 101. Since the space between the wall surfaces farthest from 108 also passes through and is discharged from the undercut 108, a more effective ventilation can be obtained without causing stagnation in the space.

  And considering the purpose of preventing the stagnation of the space as the installation position of the air outlet 1, it is desirable to install it on the ceiling surface directly above the undercut 108, but the air outlet 1 is located in the vicinity of the wall surface closest to the ventilation unit 101. As in the case of installation on the ceiling, it is desirable that the indoor introduction pipe be installed at a position close to the undercut in a plan view within a range in which abrupt bending does not occur. And if you use an undercut of the door or an air vent installed on the door as the air circulation means, obstacles such as furniture will not be installed in the vicinity of the door, so even if the lifestyle changes, etc. Even in the case where the flow is performed, since the flow of fresh air supplied from the blower outlet 1 is not hindered in the vicinity of the blower outlet 1, a sufficient ventilation effect can be obtained without causing stagnation.

  In winter, the fresh air supplied from the air outlet is cold and hot during the rainy season and in the summertime. Therefore, in the case of the air outlet 1 shown in FIG. 3, the angle with respect to the communicating pipe end 28 and the panel inner surface 30 is set in the horizontal direction, and in the case of the air outlet 1 shown in FIG. Therefore, since the fresh air flows in the vicinity of the ceiling, it can be prevented from directly hitting the occupants, and a draft feeling can be prevented. Here, if the set angle at each air outlet is set to 0 degree or more and 45 degrees or less with respect to the ceiling surface, fresh air supplied from the air outlet flows in the summer due to the Coanda effect. Can be prevented. However, since the specific gravity is larger than the air in the room in winter, there is a possibility that the occupant will be directly hit and a draft will be given. Therefore, considering the winter season, it is more preferable to set the setting angle to 0 degrees or more and 30 degrees or less with respect to the ceiling surface. In addition, FIG. 9 is a measurement result of the wind speed distribution in the winter when the set angle in the winter is 30 degrees, X is a distance from the air outlet in a plan view, and Y is a height from the floor of the room, The blower outlet is installed in the position of X = 0mm and Y = 2400mm. And since the maximum wind speed at Y = 1800 mm is about 0.1 m / s, even if the occupant stands, he / she does not care.

  Moreover, in the case of a room with a large aspect ratio in plan view, fresh air supplied from the air outlet does not reach the wall surface farthest from the air circulation means, and stagnation occurs in the vicinity of the wall surface. Therefore, if the set angle is set to 0 degrees or more and 20 degrees or less with respect to the ceiling surface, the fresh air travels along the ceiling due to the Coanda effect, so that the reach distance of the fresh air is extended, and as a result, reaches the wall surface. Stagnation can be prevented. FIG. 10 shows the measurement result of the wind speed distribution when the set angle is 20 degrees with respect to the ceiling surface. The definition of X and Y and the position of the outlet are the same as those in FIG. Here, when the set angle is 30 degrees, the maximum wind speed at X = 2500 mm is about 0.1 m / s as shown in FIG. 9, whereas when the set angle is 20 degrees, as shown in FIG. Therefore, it is considered that the reach distance is extended.

  Further, by reducing the opening area of the outlet opening 32 of the outlet shown in FIG. 3 and the opening area of the outlet opening 43 of the outlet shown in FIG. 4, the blowing speed of the fresh air is increased and the reach distance is extended. Is possible.

  Furthermore, by blowing out fresh air supplied from the air outlet in multiple directions or in a fan shape, the fresh air supplied from the air outlet flows in the direction of the plurality of wall surfaces of the living room. Better ventilation effect.

  The present invention makes it possible to reduce the energy consumption of the ventilation system and the initial cost without giving a draft to the occupants, to reliably supply the necessary ventilation, and to stagnate contaminated air in the room. It is useful as a ventilation system for ventilating the inside of a building and a blowout outlet that is a component of the ventilation system, which can provide a ventilation system that can be prevented from occurring.
