Description

  The present invention relates to an air outlet, and more particularly, to a small air outlet for a floor suitably used for task air conditioning and an air conditioning system using the same.

  Conventionally, improvement of energy saving performance has been a major issue in buildings such as office buildings. At the same time, there is also a need to improve the comfort of the indoor environment and improve the work efficiency of users. In order to satisfy these requirements, an air conditioning system called task ambient air conditioning, which combines task air conditioning and ambient air conditioning, is being promoted in buildings. Task air-conditioning is air-conditioning for a task area in which a building user performs an operation (task), and particularly refers to controlling an environment such as temperature, humidity, and air flow in an area near each user. Ambient air-conditioning refers to air-conditioning of a portion around the task area (ambient area), and refers to controlling the overall environment of the room.

  In task ambient air-conditioning, after controlling the base environment by ambient air-conditioning, it is possible to control the elements that vary by task air-conditioning for each individual user. For example, in summer, the base room temperature is set at 27 ° C, and in places where users are present, it is possible to achieve both comfort and energy saving performance by increasing the coolness by lowering the temperature or increasing the air volume. Become.

  As one of such task air conditioning, there is a technique of providing an outlet for blowing regulated air (for example, cool or warm air or humidified air) for each of a plurality of task areas. In this case, by holding the adjusted air in the space between the floor slab and the floor and blowing the air through the outlet, it is possible to adjust the environment to a preferable environment for each task area. In particular, by making it possible to adjust the presence / absence of blow-off and the amount or direction of blow-off, environmental control for each user can be realized.

Various methods have been proposed for improving the operability and the ease of adjustment of floor outlets used for such task air conditioning. For example, Patent Literature 1 discloses that an outlet is provided at a tip of a telescopic intake duct installed on a floor. It is also disclosed that an air outlet and an adjusting mechanism for adjusting the air volume and the air direction and a fan for supplementing the air volume are provided at the outlet.
Patent Document 2 discloses that an opening / closing means for opening or closing an arbitrary outlet from a plurality of outlets is provided.
Patent Document 3 also discloses a configuration including a shutter for changing the opening / closing state of the outlet and a controller for operating the shutter.

[Embodiment]
<System configuration>
FIG. 1 is a schematic diagram illustrating a state in which the task air-conditioning system 1 of the present embodiment is applied, and shows a cross section of a room located on one floor of a building. The room is generally a space defined by a floor slab 10 that is a boundary with a lower layer, a ceiling slab 40 that is a boundary with an upper layer, and a wall surface 70 that is a boundary with the next room or outside the building. The floor slab 10 defines the lower boundary of the room, and the ceiling slab 40 defines the upper boundary of the room. The floor slab 10 may also serve as a ceiling slab of a lower level. Similarly, the ceiling slab 40 may also serve as a floor slab of an upper hierarchy. The wall surface 70 is formed of a structure such as a wall material, and the wall material may also serve as a wall surface of an adjacent room or an outer wall of a building. The lower boundary, the upper boundary, and the wall may not be completely horizontal or vertical, and may have a step, a protrusion, or a recess.

  The floor of the room has a double structure, and a floor material 20 is arranged above a floor slab 10 via a support member (not shown). As the floor member 20, it is preferable to use a combination of a plurality of square or rectangular panel members for floor. An underfloor space 30 is formed between the floor slab 10 and the floor material 20. The flooring material 20 defines a floor surface. In the example of this figure, the ceiling of the room has a double structure, but this is only an example. Below the ceiling slab 40, a ceiling member 50 supported by a support member (not shown) is arranged. A ceiling space 60 is formed between the ceiling slab 40 and the ceiling material 50. The ceiling material 50 defines a ceiling surface. In each part constituting the ceiling space 60 and the underfloor space 30, in order to prevent the adjusted cooling / heating air from escaping or to prevent dew condensation, it is preferable to use a member having a high heat insulating property or to lay a heat insulating material. .

  In this specification, a space between a floor surface and a ceiling surface in a height direction and a space surrounded by a wall surface in a width direction is defined as a living space that can be used by a user. The living space is subject to environmental control by task air conditioning. When setting the task area and the ambient area, the setting method is arbitrary, and may be determined according to the purpose of use of the room, the structure of the building, the capacity of the air conditioning system, and the like. As an example, a range normally used by the user in the height direction and the width direction may be used as the task area. The task area is divided into a plurality of small areas for each size, and different control can be performed for each of the small areas. As the ambient area, for example, a range having a height equal to or greater than a predetermined value, a window, a wall, a doorway, or the like may be set.

  Further, when the seat of each user is determined, the task area may be set for each user, centering on the seat and the work area. When a partition is installed in a room, a small area may be divided for each partition. In the example of the figure, a task area is set in which the small area is near the seat of each of the users 5a to 5c. However, the ranges in which the task air conditioning and the ambient air conditioning exhibit the air conditioning effect mutually change due to changes in airflow and various external factors. Therefore, it is not always necessary to strictly define the boundary between the task area and the ambient area.

  In the description of the present embodiment, for the sake of simplicity, in the task area, air conditioning that can be controlled on demand by the user for each small area is called task air conditioning, and air conditioning that is controlled as a whole room is ambient air conditioning. Call. In the present embodiment, task air conditioning is a method using outlets arranged on the floor, and ambient air conditioning is a method using outlets on the ceiling. However, outlets may be provided on the ceiling or wall in addition to the floor for task air conditioning. Further, for ambient air-conditioning, an outlet may be provided on a floor or a wall in addition to or instead of the ceiling. In addition, radiation air conditioning may be used instead of air conditioning using airflow.

  In this example, the air conditioner 300 is provided outside the wall surface 70a. The air conditioner 300 supplies adjusted air such as cooling and heating air. The temperature of the air and the like are adjusted by a central control device (not shown) according to the season and the air temperature. However, the arrangement of the air conditioner is not limited to the outside of the room, and may be arranged in a ceiling space or a space under the floor, or an air conditioning room may be provided near the room. Here, for simplicity, only an air supply (supply air) system for supplying air-conditioned air is shown.

  The adjusted task air conditioning air 210 supplied from the air conditioner 300 is introduced into the underfloor space via the duct 311. The floor material 20 is provided with floor outlets 101a to 101c for each small area of task air conditioning. The number and arrangement of the outlets are arbitrary. As will be described in detail later, the floor outlet has a function of individually adjusting the wind direction and air volume. For example, the floor outlet 101a is in a closed state, and no airflow is generated. The floor outlet 101b blows out the airflow 221 in the direction of the user 5b with a small airflow. The floor outlet 101c blows the airflow 222 upward with a strong air volume.

  Note that, in addition to the air blown by the fan, an upward airflow generated when the inside of the underfloor space becomes a positive pressure by air supply may be used. In addition to the individual control, the blowout air volume and the wind direction may be controlled by the central control. The air that has flowed out from the floor outlet is blown out as a swirling flow, and the surrounding air is mixed while being attracted, thereby performing air conditioning in the room. Although the entire underfloor space is a chamber in this drawing, a duct may be used to guide air from the air conditioner to each outlet.

  The adjusted ambient air-conditioning air 220 supplied from the air conditioner 300 is introduced into the ceiling space via the duct 321. A plurality of ceiling outlets 50a are provided in the ceiling member 50, and the ambient air-conditioning air 220 accumulated in the ceiling space is blown into the room. Any ceiling outlet may be used, such as an embedded unit, a unit having a fan, or a unit having a nozzle or a slit. Further, as the ceiling material, a film-shaped member having a plurality of small holes and used for air conditioning called a film ceiling or a cloth ceiling may be used. Further, an indoor unit of the type used in a conventional air conditioner may be used for ambient air conditioning.

<Arrangement>
FIG. 2 is a plan view showing an example of an installation method and an installation state of a floor outlet in a room to which the air conditioning system is applied. In the figure, users and office furniture such as desks and chairs are omitted. The floor of the room has the double structure described above. The floor panel material 420 laid in the room is the upper layer of the double structure, and corresponds to the floor material 20 in FIG. In the present embodiment, outlet holes 430 are provided in the floor panel material 420. That is, one side of each floor panel member 420 is provided with a hole having a size half that required for installing an outlet, and is usually covered with a removable cover. As shown, two adjacent floor panel members 420 are laid so that the respective outlet holes 430 are joined, so that the outlets installed in the underfloor space can be exposed to the living space and used for the user. become.

  In the present embodiment, the floor outlet 101 is installed in the outlet hole 430. In the figure, the outlet hole 430 where the floor outlet 101 is installed is shown in black. In order to easily install the floor outlet in the outlet hole, the floor outlet has a body portion fitted into the outlet hole and a face portion exposed inside the room, and the face portion is hooked and fixed to the floor surface. It is good to have a structure. For example, in a floor panel material that is relatively widely used, the outlet hole is a substantially square having a side of 85 mm. In that case, the cross-sectional shape of the body portion of the floor outlet 101 is set to be a substantially square size that fits into the outlet hole. Alternatively, an adapter member may be used when the sectional shape of the floor outlet is different from the shape of the outlet hole.

By using the outlet hole in this way, the floor outlet can be installed at an appropriate position according to the size of the user's task area (small area) and the user interval. For example, in the drawing, the floor outlets 101a to 101c contribute to air conditioning of the small areas 260a to 260c, though depending on the wind direction, the air volume, and external conditions, respectively. Further, since a large number of outlet holes are usually provided on the floor, the degree of freedom of the installation position of the floor outlet is increased, and the task area can be flexibly determined. Also,
By using the existing outlet holes, the strength of the floor panel material is not impaired. However, instead of using the outlet hole provided in advance, a hole may be formed at a desired position.

<Structure of outlet>
An example of the overall structure of the floor outlet 101 of the present embodiment will be described with reference to FIG. The floor outlet is roughly connected to a circular face portion 170 exposed on the floor surface, a wind direction adjusting portion 180 detachable from a circular recess in the center of the face portion 170, and a lower portion of the face portion 170 when installed. The shutter drive unit 160 includes a fan unit 150 connected to a lower portion of the shutter drive unit. A foot switch 190 is provided so that a part of the face part 170 is exposed indoors. The face 170, the shutter drive 160, and the fan 150 may be connected in any manner. However, if the three members are connected using long screws, both secure fixing and easy separation can be achieved.

  FIG. 4 is a plan view of the installed floor outlet viewed from above. The face part 170 in this example can be divided into three parts when viewed from above. The central portion of the face portion is a circular concave portion 171 in a top view, and is shaped so as to fit with the substantially disk-shaped wind direction adjusting portion 180. With such a configuration, the user can freely adjust the wind direction by rotating the wind direction adjustment unit 180 fitted in the recess 171 in any direction of 360 °. There is a flat portion 172 around the periphery, and there is an inclined portion 173 that gradually slopes toward the floor around the periphery. According to such a configuration, the stability at the time of installation is improved, and it is possible to prevent the user from being caught when walking or moving office furniture.

  In the figure, of the foot switch 190, the upper part of the cylindrical housing part 192 and the lighting part 191 made of LED embedded in the housing part are exposed indoors. The housing section 192 of the foot switch is installed in a hole formed in the face section 170 so as to be able to be pressed. However, the lighting section is not limited to the LED. Moreover, you may provide a lighting part in a position different from a foot switch.

  Further, the wind direction adjusting unit 180 includes a circular outer peripheral portion 181 having a diameter slightly smaller than the inner diameter of the hollow portion, and a plurality of elongated plate portions 182 arranged in parallel with the outer peripheral portion 181. With this structure, a slit portion 183 for passing the adjusted air from below is formed. In FIG. 4, the upper shutter of the depression is seen from the gap of the slit 183. The plate portion 182 is arranged so as not to be perpendicular to the floor surface when the outlet is installed. By providing such an angle, when the user manually rotates the wind direction adjustment unit, diversity is generated in the direction in which the airflow is blown out. Note that a plurality of wind direction adjustment units having different angles from each other may be prepared so that the user can use a desired type. The angle is preferably about 60 ° to 80 °, and is typically 70 °.

  FIG. 5A is a plan view of the face part 170 as viewed from above, and shows a state in which the wind direction adjustment part has been removed from the depression part 171. The bottom surface of the recess 171 also serves as the upper shutter 174. The peripheral part of the upper shutter 174 is connected to and fixed to the flat part 172. By combining the upper shutter with the lower shutter of the shutter drive unit, it becomes possible to block the airflow passage. The upper shutter 174 in this example has a shape in which a plurality of plate-shaped spokes 177 radially arranged around the hub 176 are combined with the hub 176 as a center. The airflow sent from below by the fan blows upward through the gap 175 between the spokes as a passage. A hole 178 for inserting a foot switch is formed in the face portion.

FIG. 5B shows the lower shutter 162 arranged on the side closer to the floor surface (side connected to the face portion) in the shutter driving unit 160 at the time of installation. The lower shutter also has a shape in which a plurality of plate-like spoke portions 167 are radially connected around the hub portion 166 with the hub portion 166 as a center portion, and a gap 165 is formed between the spokes. The lower shutter 162 is sized to fit within a substantially rectangular cross section when viewed from above the shutter driving unit, and has an angle occupied by at least one gap 165 in the rotation direction about the center of the hub (reference numeral A) as the rotation center. It is rotatable by the minute (reference R). The power of rotation is arbitrary, and in this example, the advancing / retreating motion of a linear motion solenoid (not shown) connected to the small hole 169 is converted into the rotational motion of the shutter. Any other components such as a rotary solenoid and a motor may be used as long as they can obtain rotational power.

  The lower shutter performs such a rotational movement, so that the open / closed state of the passage between the room and the underfloor space can be easily changed. That is, when the gap 175 of the upper shutter and the gap 165 of the lower shutter overlap each other, an airflow path is formed. On the other hand, when the gap portion 175 of the upper shutter and the spoke portion 167 of the lower shutter, and the spoke portion 177 of the upper shutter and the gap portion 165 of the lower shutter overlap each other, a closed state is established. Since the lower shutter may come into contact with the upper shutter or the like, it is preferable to improve the friction resistance and durability by using a self-lubricating resin for the blades of the lower shutter.

  The opening and closing of the shutter may be linked with the operation control of the fan by the foot switch. For example, when the stop of the fan is instructed by the foot switch, the shutter is simultaneously closed. This prevents airflow from the underfloor space generated by positive pressure, and can more accurately reflect the user's intention to stop task air conditioning. Note that the shutter is not limited to the rotation type. For example, a linear motion system or a system in which the wing member is folded or expanded may be used. However, if a circular shutter as shown is used, the air volume and the air direction can be made uniform. Power for opening and closing the shutter may be manual.

  FIG. 6 is a side view of the floor outlet 101. As shown, the face portion 170 is considered to be divided into a body portion 179a and a top portion 179b. When the body portion 179a is inserted under the floor, the top portion 179b above the body portion is caught by the floor surface or the edge of the outlet hole, and the outlet is fixed to the floor. Therefore, the body portion 179a is designed to have a shape and size (here, a substantially square whose one side of the cross section is slightly smaller than 85 mm) so as to fit in the outlet hole. The shutter drive unit 160 and the fan unit 150 are also designed to have a shape and a size that can be inserted into the outlet hole. In the example shown in the figure, the cross section of each member is substantially the same, and the three members are fixed to each other by four screws 154. The shutter driving unit 160 includes a connector 164 for connecting a control line to receive power supply from an external power supply, input a control signal from an external control circuit, and transmit state information to the outside. I have.

  FIG. 7 is a bottom view of the floor outlet 101. As the fan unit 150, for example, a small fan having excellent quietness, such as that used for a PC, can be used. The fan section 150 has a foot switch bearing section, and controls the state of airflow in response to the user pressing the foot switch. The fan unit may be connected to an external power supply or control circuit via a control line (not shown), and may receive a control command or transmit a state signal that is information indicating a state. Although FIG. 7 shows the back surface of the top portion of the face portion 170, a brace or notch may be provided on the back surface for the purpose of reinforcing, preventing slippage, and reducing member costs.

  The material of each member constituting the floor outlet can be arbitrarily selected according to required performance and cost. For example, resin, metal such as aluminum and stainless steel, and the like. Also, the processing method is arbitrary, such as injection molding, casting, and lathe processing. Further, the size of each member constituting the floor outlet can be freely determined according to required performance and cost. The same applies to the performance of the fan. However, the height of the entire outlet needs to be within the range of the underfloor space which is generally 100 to 200 mm.

  Due to the characteristic of being installed on the floor, the foot switch 190 is required to have durability such that the foot switch 190 is not broken even if it is stepped on with a strong force or a load is placed on the switch. In FIG. 6, the height of the top of the foot switch when no force is applied is denoted by a symbol T, and the height of a flat portion on the surface of the face portion is denoted by a symbol S. At this time, it is preferable that the height T of the top portion is equal to or lower than the height S of the flat portion. Thus, the foot switch does not break even when a strong force is applied. As described above, in order to realize a function in which the top of the foot switch has a height equal to or lower than the surface of the top portion, for example, the housing 192 may have a structure in which the entire length changes according to an applied force. . As the variable length structure, for example, a structure in which two members slidable up and down with each other can be used. Alternatively, an elastic member such as a spring may be arranged at the base of the housing 192.

<Operation>
FIG. 8 is a block diagram illustrating a configuration related to control of the air conditioning system of the present embodiment. In this drawing, only one of the outlets is shown. In this figure, the floor outlet 101 related to task air conditioning and the ambient air conditioner 330 related to ambient air conditioning change operating states according to both the operation by the user 5 and the remote operation by the information processing device 208 for central control. However, the processing of the present invention can be performed as long as there is at least a floor outlet that operates according to a user operation.

  The information processing device 208 is a device including arithmetic resources such as a CPU and a memory, user interfaces such as a mouse, a keyboard, and a display, and communication means, and can suitably use a PC or a workstation. The information processing device 208 has a function of receiving data from sensors and transmitting control values to various air conditioners or their control circuits. The human sensor 211 is a sensor that determines whether a user is present in a predetermined area in the room and transmits the information to the information processing apparatus as personal information. Any human sensor can be used, such as an infrared sensor, an ultrasonic sensor, or a sensor combining an optical camera and image analysis software. The environment sensor 212 acquires at least room temperature information and transmits the acquired information as an environment detection value to the information processing apparatus. Alternatively, humidity, illuminance, and the like may be acquired. In this example, the human sensor and the environment sensor acquire person information and an environment detection value for each task area (small area), and person information and an environment detection value for the entire room. Data for each task area is mainly used for task air conditioning control, and data for the entire room is mainly used for ambient air conditioning control.

  In this example, a plurality of floor outlets (101a, 101b, 101c ...) are controlled by the control circuit 102. The control circuit 102 controls a plurality (for example, eight) of floor outlets. When the user 5 presses the foot switch 190, a pressing signal is transmitted to the control circuit. The control circuit transmits a wind speed control parameter to the fan unit 150 and an opening / closing control parameter to the shutter driving unit 160 according to the current operation state and the number of times the switch is pressed. However, the relationship between the control circuit and the floor outlet is not limited to this figure, and each floor outlet may have a control circuit.

  FIG. 9 is a table illustrating combinations (operation modes) of the states of the fan, the shutter, and the LED. Here, it is assumed that the fan unit has three states of “stop / low air flow / high air flow” and the open / close state of the shutter has two states of “closed / ventilated”. Further, the control circuit may receive a status signal from the fan unit 150. The state signal is represented by any one of, for example, "stop / weak / strong", and is used for control by the control circuit or the information processing device.

In the example of FIG. 9A, the operation mode of task air conditioning is switched every time the foot switch is pressed. Specifically, combinations (1-1) to (1) of the operating states of the fan, the shutter, and the LED
The switching of -3) is repeated. The combination (1-1) is a state where the task air conditioning in the target task area is off. When the user presses the switch once, the operation shifts to the combination (1-2), the operation becomes weak, and the LED flashes. When the user further depresses the switch, the operation shifts to the combination (1-3), the strong operation state is established, and the LED is constantly lit.
In FIG. 9B, the number of combinations is four. The difference from FIG. 9A is that the combination (2-2) exists. In this state, the fan is stopped but the shutter is open. Therefore, mild air conditioning is performed by blowing out from the underfloor space under positive pressure.

  The order and combination of the states of the fan, shutter, and LED shown in FIGS. 9A and 9B are merely examples, and the present invention is not limited thereto. Further, the operating state of the fan may be controlled more finely. Further, a mode switching function may be provided in the air conditioning system. The mode switching function is a function of switching between a plurality of operation patterns (for example, the pattern in FIG. 9A and the pattern in FIG. 9B) according to an instruction of the information processing apparatus or a user operation.

  Conventionally, when adjusting the air volume at a general floor outlet, a dial-type knob using a variable amplifier or the like, or a different button (for example, a weak / medium / strong button) is used for each desired air volume. Was. However, such methods require the user to bend down or reach when making the adjustment. On the other hand, in the case of the switch of the present invention, it is only necessary to extend the leg while sitting on the seat to adjust, and thus the comfort is improved.

  When a load is placed on the foot switch, the switch always outputs a pressing signal. Therefore, the control circuit or the information processing device detects the duration of the pressing signal, and if the pressing state continues for a certain period of time (for example, 10 seconds), the state switching or the task air conditioning may be stopped.

  As described above, by using the foot switch for the floor outlet of the task air conditioner, the user does not need to bend down or reach when controlling the air volume, and the user's comfort is improved. Also, as described above, the use of the shutter in conjunction with the foot switch also eliminates the need to manually open and close the shutter, thereby improving comfort. In addition, if a lighting means such as an LED is used, the user can easily know the current state of the task air conditioning. In addition, if central control is performed using the information processing device and a human sensor or an environment sensor, task ambient air conditioning that balances the entire living space can be realized. In addition, by using the existing outlet hole when installing the outlet, the load of the installation work can be reduced and the strength of the floor can be maintained. In addition, since the outer periphery of the recessed portion and the outer periphery of the wind direction adjusting portion are circular, the blowing direction can be freely adjusted. Furthermore, by showing the structure and combination of the members as shown in each drawing, it is possible to realize a compact structure that can be used even when the underfloor space is small while using both the fan and the shutter.

  The various configurations as described in this specification may be combined in any manner, and any combination can provide an effect that cannot be obtained with a conventional floor outlet.
