Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ventilation structure used for a floor-floating centralized air conditioning system inside a building.

[0002]

[Prior Art]

 Floor-blowing centralized air conditioning systems are often used mainly for heating and ventilation applications. As shown in FIG. 4, a floor duct 105 provided with an air outlet 104 is laid under the floor of each room on a floor plate 103 near the outer wall 102 of a hollow floor panel 101. The floor duct 105 is heated by supplying hot air generated by an air heating device (not shown), but in the case of ventilation as well, in order to avoid a sudden change in room temperature, the outside air taken in is exchanged with exhaust air for a little heat. The temperature is raised and introduced into the floor duct 105. Since the floor duct 105 is laid in this way, only the air outlet 104 appears in each room, and the facility has a simple appearance.

[0003]

[Problems to be solved by the device]

 However, the ventilation structure in the conventional floor-blow-out type centralized air conditioning system has a drawback that it is difficult to cope with a large change in the required ventilation amount. That is, when using an open-type heating appliance, a stove, etc. for temporary use, or when gathering a large number of people, such a situation is usually set in the initial ventilation setting for the reason of reducing operating costs and noise. Since it does not contain it, naturally the ventilation capacity is insufficient. In anticipation of such a situation, if a separate ventilation fan with a wall is installed, it will overlap with the presence of the air outlet on the floor of the floor-type centralized air conditioning system, which is a problem. Also does not balance. Also, when sleeping in a specific room during the non-heating season, even if the ventilation fan attached to this floor blow-out type central air conditioning system is operated, the air will be blown into each room and the specific room It is generally difficult to concentrate only on. Therefore, this room can get hot due to lack of ventilation, but it is inconvenient for crime prevention to open the windows to provide ventilation. An object of the present invention is to provide a building floor ventilation structure that effectively uses an air outlet and a floor duct on the floor of a floor-type centralized air conditioning system.

[0004]

[Means for Solving the Problems]

 The building floor ventilation structure according to the present invention is provided with an air outlet on the floor plate in the hollow portion near the outer wall of the hollow floor panel, and the floor outlet type is arranged along the outer wall below the floor plate. A floor duct of a centralized air-conditioning system, a lateral member along the outer wall of the floor panel from a side surface of the floor duct on the outer wall side, and a horizontal member on which the outer wall is placed at the same height as the floor panel. An outside air intake hole passing through the member to the outside wall surface, an electric outside air suction fan arranged at the outlet of the outside air intake hole on the floor duct side, and an outside air intake hole of the outside air intake hole. It is composed of an insertion / opening type shutter equipped with a remote control mechanism and a horizontally long curtain plate mounted on the vertical surface on the outdoor side of the shutter.

[0005]

[Action]

 This floor duct passes through the outside air intake hole that penetrates from the outside wall surface to the side surface of the floor duct, and is forcibly sucked into the outside air directly by the outside air suction fan, and this outside air is discharged into the room from the air outlet on the floor board. It A shutter that can be opened and closed at the entrance of the outside air intake hole can be opened and closed by remote control to prevent outside air from entering when the outside air suction fan is stopped. A horizontally long curtain mounted on the vertical surface of the shutter on the outdoor side covers the outside air intake port and the shutter. When the shutter is closed and the outside air suction fan is stopped, it can be used as an original floor-blowing centralized air conditioning system.

It is a longitudinal cross-sectional view showing a time point. In the figure, 1 is a floor panel, 11 is a side member of the floor panel 1, 2 is an outer wall, 3 is an air outlet, 4 is a floor duct, 41 is a side surface of the floor duct 4, 5 is a lateral member, and 6 is outside air. An inlet hole, 61 is an outlet of the outside air intake 6 on the floor duct side, 62 is also an inlet on the outside wall surface, 7 is an outside air suction fan, 8 is a shutter, 81 is a remote operation mechanism of the shutter 8, and 9 is a curtain plate. As shown in FIG. 1, the building floor ventilation structure of the present embodiment is a floor duct provided with an air outlet 3 on the second floor of a hollow floor near the outer wall 2 of a hollow second floor floor panel 1. Applies to 4. This floor duct 4 is for a floor-blow-out type centralized air-conditioning system, and is laid under the floor plate on the second floor along the outer wall 2 at a position close to the outer wall 2. The outer wall 2 is also a hollow panel which is filled with a heat insulating material.

From the side surface 41 of the floor duct 4 on the outer wall 2 side, the side member 11 along the outer wall 2 of the floor panel 1 for the second floor and the outer wall 2 arranged at substantially the same height as the floor panel 1. An outside air intake hole 6 is provided through the horizontal member 5 for mounting the second floor wall panel, an outside air suction fan 7 is attached to one end thereof, and a shutter 8 is attached to the other end thereof. In detail, although the horizontal member 5 has a barrel difference here, a grooved steel having a heat insulating material buried in the groove was used, and the heat insulating material was arranged facing outward. The outside air intake hole 6 is a round hole in the side surface member 11 portion of the floor panel 1 and a laterally long groove-shaped hole in the horizontal member 5 portion. The outside air suction fan 7 is an electric turbofan and is located at the floor duct side outlet 61 of the outside air intake hole 6, and the shutter 8 is an insertion opening / closing type with a remote control mechanism 81. It is arranged at the outer wall side inlet 62.

The shutter 8 is a horizontally long plug made of a heat insulating material and having a shape corresponding to the groove-shaped hole of the horizontal member 5, and a curtain plate 9 is attached to the outer vertical surface thereof. The curtain plate 9 hides the outside air intake hole 6 and the shutter 8 and the lateral member 5 in the vicinity so as not to be seen from the outside, and is a horizontally long plate having a color tone and a shape which doubles as a decorative plate in this portion. A remote control mechanism 81 for back-and-forth movement for opening / closing operation of the shutter 8 integrated with the curtain plate 9 toward the outer wall side entrance 62 is provided with a small motor and screw holes on the left and right of the horizontally long shutter 8. A front-rear moving mechanism that combines an attached gear and a screw shaft is arranged for remote control. The remote operation is linked with the operation operation of the outside air suction fan 7.

The outside air that has entered the floor duct 4 is discharged into the room from the air outlet 3 on the floor plate and is converted. The ventilation volume has sufficient capacity because each volume of the building floor ventilation structure has a capacity that can cope with the above-mentioned large fluctuation of ventilation volume in advance. When the shutter 8 is moved in the indoor direction, the closed state shown in FIG. 3 is established, the outer wall side inlet 62 is closed, the outside air suction fan 7 is stopped, and the outdoor air suction is stopped. With this, the floor duct 4 is restored to the original floor surface type centralized air conditioning system, and centralized heating and ventilation can be performed.

As described above, the building floor ventilation structure of the present embodiment uses the floor duct and the air outlet of the floor-blow-out type centralized air-conditioning system as they are, and very effectively utilizes them to cope with a large change in the ventilation amount. It can be done indoors and outdoors without losing its appearance. Since the floor duct and the air outlet are used, the equipment cost can be reduced. It is also preferable for crime prevention because it allows large-scale ventilation without opening windows.

The building floor ventilation structure of the present invention can be modified in various ways other than the above embodiment. For example, the remote control mechanism of the shutter may be an electromagnetic type using a solenoid coil and may have a simplified structure. Alternatively, the outside air suction fan may be a slender sirocco fan, and the outside air intake hole and the shutter may be horizontally long to further reduce the height of each of these parts.
