DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilator which is disposed on a floor in a space to be air-conditioned and ventilates by blowing air conditioning gas into the space or by sucking gas in the space. And a ventilation system using the ventilation device.

[0002]

2. Description of the Related Art In air conditioning for large indoor spaces such as movie theaters, halls, and theaters, a plurality of outlets for blowing conditioned air are installed on a ceiling or a wall, and passages such as below a chair provided as a seat for customers. A suction port is provided on the floor other than the room, so that the air in the room can be quickly exchanged so that quick air conditioning of the room can be performed. An example of a conventional suction port device installed on the floor of such an indoor space is shown in FIGS. FIG. 9 is a partially omitted plan view and a cross-sectional view of a conventional suction port device, and FIG. 10 is an explanatory view of a blowing state in the conventional suction port device.

In each of the drawings, a conventional suction port device 100 is shown.
Is formed in a hollow rectangular box-like body, the upper surface of which is a punching surface on which a large number of opening holes 101 are formed. This is a configuration provided on the floor 50. In the conventional suction port device 100 having the above-described configuration, the air in the room is sucked into the interior through the opening 101 and discharged to the duct 51. By performing such a suction operation, particularly in the case of cooling, the cool air blown out from the ceiling can be guided to surely reach the vicinity of the floor 50, and the air conditioning effect can be improved.

[0004]

The conventional suction port device is configured as described above, is formed in a thin shape suitable for installation under a chair or the like, and is used in principle for suction. It is desirable from the point of heating efficiency to perform floor blowing, and it is difficult to install the outlet in addition to the suction port on the floor because of the floor structure and the arrangement of chairs.
At the time of heating, the inlet was sometimes used as an outlet.

As described above, when the conventional suction port device 100 is used for blowing, the air flow is blown out from the opening 101. However, since the blowing state cannot be adjusted, the air flow goes straight upward from the duct 51 as it is. Depending on the shape of the lower portion of the chair 40 and the floor 50, the impact is strongly affected by the lower portion of the chair 40 and the shape of the floor 50, so that not only the desired airflow is not obtained but the effect is limited, but also the wind direction of the blown airflow and the chair 40 As shown in FIG.
As shown in (2), there is a problem that the airflow blows directly to a person sitting in a seat behind the chair 40 where the suction device 100 is located, thereby causing discomfort.

On the other hand, as a floor-installed outlet which is not a diversion of the inlet device for the outlet application, a conventional open-type outlet has been used.
Some of them are described in JP-A-97244 and JP-A-8-327091, and one example is shown in FIG. The air outlet device 200 of the floor 50 installation type shown in FIG. 11 is normally used in a situation where there is no obstacle above the air outlet, and is designed to be installed under a chair. Therefore, when installed under the chair, there is a problem that the chair blocks the airflow, so that the airflow tends to stagnate. In order to prevent such stagnation, it is necessary to provide a larger blowing wind speed. However, in this case, there is a problem that a draft is generated on the contrary and a person who sits is uncomfortable. Further, even if it is used as a suction port, there is a problem that the structure cannot be used as a suction port because the resistance at the time of suction becomes larger than that in the case of blowing out due to its structure.

[0007] Conversely, as an outlet dedicated to installation under a chair, there are those disclosed in Japanese Patent Publication No. Hei 5-34566 and Japanese Patent Laid-Open Publication No. Hei 6-193965.
One example is shown in FIG. As shown in FIG. 12, the conventional outlet device 300 for setting the lower side of the chair has a wind direction of the blown air flow and the chair 40 irrespective of the shape of the lower part of the chair 40 and the floor 50.
Although it is possible to set the air flow balance in the front and rear to a desired state, if it is used as an intake port, the resistance at the time of intake from the complicated structure becomes large, and as in the above case, as the intake port There was a problem that it could not be used.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is possible to adjust the blowing state, to perform blowing without being affected by the shape of a chair or a floor surface, and to suppress the resistance during suction. It is an object of the present invention to provide a ventilation device capable of appropriately coping with both suction and blowing, and a ventilation system using the ventilation device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS (First Embodiment of the Present Invention) Hereinafter, a ventilating apparatus according to a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a partially omitted plan view and a cross-sectional view of the ventilator according to the present embodiment in a suction state, and FIG. 2 is a partially omitted plan view and a cross-sectional view of a ventilator according to the present embodiment in a blowout state. FIG. 3 is an explanatory view of a blowing state in the ventilation device according to the present embodiment.

In each of the drawings, the ventilating apparatus 1 according to the present embodiment is formed of a hollow, substantially box-like body, and has a large number of holes 11a as the openings on the upper surface of the substantially box-like body.
The apparatus has a configuration in which an apparatus main body 11 mounted and disposed thereon and a shielding plate 12 as airflow guide means slidably disposed in a hollow portion of the apparatus main body 11 are provided. The apparatus main body 11 has a substantially cylindrical neck portion 11b for connecting the duct 51 protrudingly provided on a predetermined surface, and is integrally provided with a plurality of holes 1 as punching surfaces.
1a is formed on the floor 50 below the chair 40 with the punching surface facing upward, and a duct 51 for supplying conditioned air and discharging indoor air is connected to the neck 11b. .

The shielding plate 12 is formed of a substantially U-shaped plate having both ends bent by a predetermined length.
Is arranged so as to be slidable in a predetermined range along the punching surface in a direction substantially parallel to the punching surface. next,
The suction and discharge operations of the ventilation device based on the above configuration will be described. In the case of suction, the shielding plate 12
Is shifted from above the duct 51 (FIG. 1).
reference). When room air is sucked into the apparatus main body 11 through the duct 51 by a blower (not shown), air in the room is sucked into the apparatus main body 11 through the hole 11 a and guided to the duct 51. When the air in the lower part of the indoor space is sucked, the air in the upper part of the indoor space reaches the lower part, so that air exchange, that is, ventilation can be performed in the entire indoor space.

On the other hand, in the case of blowing, the shielding plate 1
2 is located directly above the duct 51 (see FIG. 2). The warm conditioned air supplied from the duct 51 is supplied to the apparatus main body 11.
After entering the inside and flowing sideways along the shielding plate 12, it blows out into the indoor space through each hole 11a at the end of the punching surface. The conditioned air is blown out after the conditioned air is guided to the end of the apparatus main body 11 by the shielding plate 12, so that the blown air flow is affected by the shape of the lower part of the chair 40 above the hole 11 a and the shape of the floor 50 such as the inclination and the stairs. It is difficult to receive the airflow, and the balance of the airflow in the front-rear direction of the chair 40 can be made appropriate. The blown-out conditioned air warms the surrounding air while moving upward in the indoor space, so that the indoor space can be efficiently heated.

As described above, in the ventilating apparatus according to the present embodiment, the slidable shielding plate 12 is disposed as a gas flow guiding means in the hollow portion of the apparatus main body 11, and the shielding plate 1 is provided.
2 can be changed by the slide adjustment of the position of the shielding plate 12 so that the shielding plate
2 can be slid to a position deviated from just above the duct 51 to reduce the suction resistance, while the shield plate 1 is blown out.
2 is adjusted right above the duct 51 to change the blowing position to the end of the device main body 11 to prevent the airflow from the duct 51 from going straight,
The influence of the shape of the lower part of the chair 40 and the floor 50 can be reduced to obtain an appropriate blow-off state, and any of the suction and the blow-out can efficiently provide an air conditioning effect to the indoor space.

In the ventilating apparatus according to the above embodiment, one shielding plate 12 is provided inside the apparatus main body 11, but the present invention is not limited to this. As shown in FIG. It is also possible to arrange the shield plate 12 so as to be slidable in a plurality of stages in parallel with the punching surface of the apparatus main body 11, and the position of the airflow can be changed by adjusting the slide of the shield plate 12, as in the above-described embodiment. The opening area of the apparatus main body 11 can be adjusted by changing the degree of overlap of the plurality of shielding plates 12, and particularly, the blowing speed of the airflow can be adjusted at the time of blowing, so that the air conditioning effect can be adjusted more finely. It can be even higher.

(Second Embodiment of the Present Invention) A ventilating apparatus according to a second embodiment of the present invention will be described with reference to FIGS. FIG. 5 is a partially omitted plan view and a cross-sectional view of the ventilator according to the present embodiment in a suction state, and FIG. 6 is a partially omitted plan view and a cross-sectional view of a ventilator of the present embodiment in a blowout state. It is.

In each of the figures, the ventilation device 2 according to the present embodiment is similar to the device main body 21 in the first embodiment.
On the other hand, as a different point, a configuration having a plurality of wind direction adjustment plates 22 that are rotatably supported at both ends in the longitudinal direction of the apparatus main body 21 and are arranged in parallel, instead of the shielding plate 12. It is. The wind direction adjusting plate 22 is formed of a substantially rectangular plate-like body whose both ends in the longitudinal direction are pivotally supported by the apparatus main body 21, and is disposed so as to be adjustable in a plurality of parallel directions in parallel with the long side direction of the apparatus main body 21. It is a configuration that is performed.

Next, the suction and blow-out operations in the ventilator based on the above configuration will be described. In the case of suction, each wind direction adjustment plate 22 is set in advance in a direction parallel to the extension direction of the duct 51 (see FIG. 5). When suction is performed into the apparatus main body 21 through the duct 51 by a blower (not shown), air in the indoor space is sucked into the apparatus main body 21 through the holes 21a, passes between the respective wind direction adjustment plates 22, and is guided to the duct 51. I will As in the first embodiment, when the air in the lower part of the indoor space is sucked, the air in the upper part of the indoor space reaches the lower part, and air exchange, that is, ventilation can be performed in the entire indoor space.

On the other hand, in the case of blowing, the wind direction adjusting plate 22 is inclined with respect to the direction in which the air flows straight from the duct 51.
The direction of the tilt is such that the airflow balance in the front-rear direction of the chair is appropriate, and the side closer to the front of the chair is forward and the side closer to the rear of the chair is rearward (see FIG. 6). The warm conditioned air supplied from the duct 51 enters the apparatus main body 21, is guided in each direction along the wind direction adjustment plate 22, and blows out into the indoor space through each hole 21 a of the punching surface. The conditioned air is prevented from traveling straight out of the duct 51 and blown out, and is blown out obliquely by being guided by the wind direction adjusting plate 22, so that the blown-out airflow is reduced in the shape of the lower part of the chair 40 above the hole 21 a and the inclination of the floor 50. It is hard to be affected by the shape such as the step shape, and the airflow can be blown out so that the airflow does not go directly to the person sitting in front of and behind the chair 40. As in the first embodiment, the blown conditioned air warms the surrounding air while moving upward in the indoor space, so that the indoor space can be efficiently heated.

As described above, in the ventilating apparatus according to the present embodiment, a plurality of wind direction adjusting plates 22 capable of adjusting the angle are provided in the hollow portion of the device main body 21 as the air flow guiding means, and the air direction guiding plate 22 guides the air. It is possible to change the angle at which the air flow enters and exits by adjusting the direction of the wind direction adjusting plate 22, so that the wind direction adjusting plate 22 can be in parallel with the extension direction of the duct 51 to reduce the suction resistance at the time of suction, and the wind direction adjusting plate 22 at the time of blowing. By adjusting the direction of the blown airflow from the direction of the straight flow of the airflow from the duct 51, the influence of the shape of the lower part of the chair 40 and the floor 50 can be reduced to obtain an appropriate blowout state. On the other hand, an air conditioning effect can be efficiently provided.

In the ventilating apparatus according to the above embodiment, a plurality of wind direction adjusting plates 22 are arranged inside the apparatus main body 21 at intervals so as not to be in contact with each other. As shown in the drawing, two adjacent wind direction adjusting plates 22 can be arranged in the apparatus main body 21 at an interval at which they can come into contact with each other over a predetermined angle range, and a ventilation area between the two wind direction adjusting plates 22 can be provided. Can be opened and closed by each wind direction adjusting plate 22, so that at the time of suction, the direction of each wind direction adjusting plate 22 is made substantially parallel to the duct extension direction to open between the wind direction adjusting plates 22 (see FIG. 7A). While the air flow can be directed toward the duct 51 without resistance, the air flow direction adjustment plates 22 are brought into contact with each other in the ventilation area at the time of air blowing to form a closed portion at the center (see FIG. 7B), and the air flow blowing position and opening The area In addition to the adjustment of the airflow direction by the direction of the wind direction adjustment plate 22, the airflow state can be optimized in each state of the airflow in each state of the airflow, such as being able to optimize the airflow state, such as the balance of the airflow in the front-back direction of the chair 40 at the time of the airflow. By optimizing the flow, air conditioning performance can be improved.

In the ventilating devices according to the first and second embodiments, the upper surface of the device body is formed as a punching surface having a large number of holes. However, the present invention is not limited to this. Other shapes that can be moved in and out with low resistance, such as a wire mesh surface or a simple opening, can also be used. Further, in the ventilation device according to each of the first and second embodiments, the device main bodies 11 and 21 that match in the front-back direction of the chair 40 are provided.
The configuration is such that the shielding plate 12 can be moved or the wind direction adjustment plate 22 can be tilted in the direction of the short side of the upper surface, but the present invention is not limited to this. You can also. Also,
The main body of the apparatus is not limited to a rectangular box, but may have another shape such as a cylindrical shape.

In the ventilators according to the first and second embodiments, the main bodies 11, 21 are connected to the duct 51. However, the present invention is not limited to this. It may be configured to be connected to a provided chamber or to a predetermined underfloor space provided in advance as an air passage. Further, the first
The ventilation device according to each of the second and third embodiments is arranged on the floor 50 of the indoor space and used only by the ventilation device. However, as shown in FIG. It is also possible to arrange another inlet device 60 and outlet device 70 at the same time and use it as a ventilation system in combination with the ventilator 1, and from the outlet device 70 above the indoor space during cooling. The blown airflow is sucked in by the ventilation device 1 of the floor 50, and the airflow blown out of the ventilation device 1 of the floor 50 is sucked by the upper suction device 60 at the time of heating.
Since the air-conditioning state in the indoor space can be appropriately adjusted, even when the installation position of the ventilation device 1 is limited to a position under the chair 40 or the like, a blowing pattern that does not give a draft feeling in consideration of the relationship with the position of the occupant is considered. Air conditioning can be efficiently performed on the indoor space by properly responding to both the cooling and the heating regardless of the conditions in the indoor space.
