Description

The present invention relates to a ceiling fitted with utensil device.

In offices, public facilities, and other office spaces, it is necessary to appropriately set the environment inside the office space, such as temperature, humidity, illuminance, noise, and fixtures, so that workers can work efficiently. It has been demanded. In particular, temperature (room temperature) is an important factor because it is one of the most directly perceptible indicators for workers.
In recent years, in offices and public facilities, it is common to adjust the temperature of the entire office space by incorporating an air conditioner in the ceiling or installing it individually. However, in the case of this method, the effectiveness of air conditioning can be determined by the worker who works in the seats around the air conditioner outlet and the worker who works in the seat away from the air conditioner outlet. There was a problem that variation would occur. In addition, it has been difficult to create an air-conditioned environment according to the user's preference such as heat and cold and physical condition.

In view of these problems, a method of installing individual air conditioners on furniture (desks) used by workers may be adopted (see, for example, Patent Document 1). By adopting this method, it is possible to individually apply air conditioning to the workers, and it is possible to prevent variations in the air conditioning condition depending on the seats seated. In addition, it becomes easier to respond to user preferences such as heat and cold without changing the temperature setting of the entire room, and it is possible to facilitate coexistence of users with different preferences in the same room. However, this method requires a large amount of power to blow air to each seat, has poor energy efficiency, and has a high equipment cost.
Therefore, the harmonious air drawn from the centrally controlled air conditioner is guided into the fixtures, distributed to each seat of the worker through the duct provided in the fixtures, and ejected from the outlet provided in the fixtures. Also proposed a method of individually applying air conditioning to workers (see, for example, Patent Document 2). According to this method, it is possible to prevent the air-conditioning condition from being varied depending on the seated seat, at a low cost.

However, these methods have a structure in which air is ejected in a certain direction from the same outlet provided in the fixture regardless of the characteristics of the air depending on the temperature. Therefore, depending on the temperature of the blown air, there is a problem that the air conditioning cannot be efficiently functioned for the user who works toward the top plate surface of the furniture (desk). Further, in order to make the air conditioning function efficiently, there is a problem that the seating position of the user is determined according to the position of the outlet.
The present invention has been made in view of the above technical problems, and it is possible to make the air conditioner function efficiently for a user who works toward the top plate surface of the fixture at a low cost. and to provide a Backed utensil device.

As a means for solving the above problems, the present invention includes a supply duct into which harmonious air for indoor air conditioning is introduced, and a fixture main body having a top plate and integrally formed with the supply duct. , A lower supply port located below the top plate of the fixture body and capable of supplying conditioned air toward the space below the top plate, and above the top plate of the fixture body and above the top plate. An upper supply port capable of supplying conditioned air toward the space and a conditioned air supplied from the lower supply port toward the space below the top plate, and the conditioned air from the upper supply port to the space above the top plate. The supply amount of is reduced from the supply amount to the space below the top plate, and the conditioned air is supplied from the upper supply port toward the space above the top plate, and the conditioned air is supplied from the lower supply port to the top plate. The supply amount of conditioned air to the lower space is reduced from the supply amount to the space above the top plate, and the adjustment member is provided, and the adjustment member is attached to the lower supply port. A lower supply amount adjusting member provided to adjust the supply amount of conditioned air toward the space below the top plate, and a supply amount of conditioned air provided at the upper supply port and adjusting the supply amount of conditioned air toward the space above the top plate. The upper supply amount adjusting member includes an upper supply amount adjusting member for adjusting, and the upper supply amount adjusting member guides the conditioned air reaching the upper supply port toward the horizontal direction or an inclined direction downward from the horizontal direction, and the top plate. The amount of conditioned air supplied to the space above the top plate is reduced compared to the side-guided state supplied to the upper space and the side-guided state, and a part or all of the conditioned air reached the upper supply port. Provided is a fixture with a top plate that operates between an upward guidance state in which the air conditioner is guided toward the upper part of the duct while avoiding the space above the top plate.
According to this configuration, the air conditioning can be efficiently functioned for the user facing the top plate. That is, in the upper and lower spaces sandwiching the top plate, the air-conditioned environment should be created according to the user's preference, physical condition, etc. by selectively supplying the harmonized air for heating and cooling from each of the upper supply port and the lower supply port. Can be done. Therefore, it is possible to provide a fixture with a top plate capable of efficiently functioning air conditioning for a user who works toward the top plate surface of the fixture at a low cost.
In this case, the amount of conditioned air supplied from each of the upper supply port and the lower supply port (air volume, blowout amount) can be adjusted individually for each of the upper supply port and the lower supply port, so that the user can adjust the supply amount (air volume, blowout amount) individually. It is possible to create an air-conditioned environment that is individually adjusted according to the taste and physical condition of the person.
In this case, when the user wants the conditioned air supplied from the upper supply port, the upper supply amount adjusting member is set to the lateral induction state, and the conditioned air is guided in the horizontal direction or the downward inclined direction to the upper side of the top plate.

The lower end of the second intermediate leg 25 is placed and fixed at a predetermined position on the floor surface F, and the upper end is connected and fixed to the corresponding portion of the beam 24.
With reference to FIG. 10, the pedestal 25c of the second intermediate leg 25 is placed and fixed on, for example, a single unit floor panel fpa. The unit floor panel fpa is formed with an opening h1 that communicates with the space K (underfloor chamber) under the floor. During heating and cooling of the office, harmonized air A is supplied in a positive pressure state from an indoor air conditioner (not shown) installed on a lower floor or outdoors, for example, in the space K under the floor. That is, in the room R in which the furniture with a top plate 10 is arranged, a floor-blowing air-conditioning system is configured in which the harmonized air A for cooling or heating is supplied into the room through the space K of the double floor.

With reference to FIGS. 2 and 3, the furniture with a top plate 10 can provide the harmonized air A flowing under the floor to each user P in a desired form, thereby providing an optimum air conditioning environment for each user P. It is said to be a possible air conditioning desk.
Inside the second intermediate leg 25 and the tesque top panel 27, the supply duct 11 is configured so as to extend vertically across both the inside of the second intermediate leg 25 and the tesque top panel 27. The supply duct 11 is configured by utilizing the second intermediate leg 25 and the desktop panel 27.

The supply duct 11 sucks in the conditioned air A under the floor through the opening h1 of the floor surface F, and the conditioned air A can be individually supplied to each seating position T. The supply duct 11 is arranged so as to extend vertically on the back side of each seating position T, and suppresses the influence of the seated person P on the foot space. The lower side (underfloor side) of the supply duct 11 is the upstream side, and the upper side is the downstream side. The supply duct 11 can supply the conditioned air A from the back side of each seating position T toward the space above and below each unit top plate 21a (the space in the range overlapping the unit top plate 21a in a plan view).

The supply duct 11 is a lower supply capable of supplying conditioned air A from a position below the beam 24 toward a space 21k1 below the top plate (a space that overlaps with the top plate 21 in a plan view and is below the top plate 21). It has a mouth 12. Further, the supply duct 11 has a space 21k2 above the top plate from the upper end position of the desktop panel 27 (generally the height of the head of the seated person P) (within a range overlapping the top plate 21 in a plan view and, for example, from the upper end of the desktop panel 27. Also provided with an upper supply port 13 capable of supplying conditioned air A toward a low position space).

Each of the lower supply port 12 and the upper supply port 13 changes its state between a state in which the conditioned air A is guided in a horizontal direction or a downward inclined direction and a state in which the conditioned air A is guided in an upward direction. An adjusting member 11c (opening / closing member 19, blowout fin 38, which will be described later) is provided. The adjusting member 11c supplies the conditioned air A from the lower supply port 12 toward the space 21k1 below the top plate, and the supply of the conditioned air A from the upper supply port 13 to the space 21k2 above the top plate is relatively reduced. In the first aspect, the conditioned air A is supplied from the upper supply port 13 toward the space 21k2 above the top plate, and the supply of the conditioned air A from the lower supply port 12 to the space 21k1 below the top plate is relatively reduced. It is adjustable between the second aspect.

Below the beam 24, the supply duct 11 includes a second intermediate leg 25, an air conditioning fan 14, a separator 15, and a lower supply port 12.

The air conditioning fan 14 includes a first air conditioning fan 14a and a second air conditioning fan 14b arranged in the width direction. The air-conditioning fan 14 supplies the conditioned air A toward the pair of seating positions T facing each other in the depth direction. The air-conditioning fan 14 is an axial flow fan whose axial direction is directed in the vertical direction, is operated by power supply, and sucks the harmonized air A under the floor toward the inside (upward) of the supply duct 11. Below the air conditioning fan 14, an on-off valve 14c is provided that opens by wind pressure when the air conditioning fan 14 operates and closes by its own weight when the air conditioning fan 14 stops.

With reference to FIG. 9, the separator 15 has a plate shape orthogonal to the depth direction, and is arranged at an intermediate position in the second intermediate leg 25 in the depth direction. Both sides of the separator 15 in the width direction are fixed to both side walls in the width direction of the second intermediate leg 25, respectively. The separator 15 partitions the internal space of the second intermediate leg 25 in the depth direction, and forms the first lower flow path 15a and the second lower flow path 15b in the second intermediate leg 25. A first hood 15c corresponding to the first air conditioning fan 14a and a second hood 15d corresponding to the second air conditioning fan 14b are formed below the separator 15, respectively.

Each hood is formed so that the corresponding lower flow path expands toward the corresponding air conditioning fan 14 in the depth direction. The harmonized air A sucked by the air conditioning fan 14 is introduced into the corresponding lower flow path via the corresponding hood. The air-conditioning fan 14 adjusts the suction amount of the harmonized air A introduced from the space K under the floor into the corresponding lower flow path by switching the rotation speed. That is, the air conditioning fan 14 is also a means for adjusting the supply amount (air volume, blowout amount) of the harmonized air A from the supply duct 11.

With reference to FIGS. 2 and 3, the lower supply port 12 is a first lower supply port 12a and a second lower supply port formed on the upper portions of the first side wall 25a and the second side wall 25b of the second intermediate leg 25, respectively. It is equipped with 12b. The first lower supply port 12a opens the upper part of the first lower flow path 15a toward the space 21k1 below the top plate on the same side in the depth direction. The second lower supply port 12b opens the upper portion of the second lower flow path 15b toward the space 21k1 below the top plate on the same side in the depth direction.

The lower supply port 12 includes, for example, an opening member 18 for forming a plurality of slit-shaped openings 18a extending in the vertical direction, and an opening / closing member 19 for opening and closing the opening 18a of the opening member 18. The opening member 18 and the opening / closing member 19 have a plate shape orthogonal to the depth direction, and the opening / closing member 19 is provided on the opening member 18 so as to overlap from the inside of the duct. A dial 19a for operating the opening / closing member 19 is arranged at the center outside the duct of the opening member 18. The opening / closing member 19 is rotated by the operation of the dial 19a, and is switched between an open state in which the opening 18a of the opening member 18 is fully opened and a closed state in which the opening 18a of the opening member 18 is fully closed. The open state of the opening / closing member 19 is a state in which the lower supply port 12 guides the conditioned air A in the horizontal direction, which is a state that can be obtained in the first aspect. The closed state of the opening / closing member 19 is a state in which the lower supply port 12 guides the conditioned air A upward, and is a state that can be obtained in the second aspect.

The opening / closing member 19 can adjust the size of the opening area of the opening member 18 according to the amount of operation of the dial 19a. The opening / closing member 19 can be in a half-open state between the open state and the closed state in addition to the open state and the closed state. The size of the opening area (in other words, the amount of air supplied by the lower supply port 12) of the lower supply port 12 can be appropriately adjusted by changing the open / closed state.

The beam 24 has side walls 25a and 25b on both sides of the second intermediate leg 25 in the depth direction and side walls 24a flush with each other, and extends in the width direction. Lower walls 24b that bend inward of the beam 24 are formed at the lower ends of the side walls 24a of the beam 24, respectively. Each lower wall 24b secures the rigidity of the beam 24, serves as a wiring receiver, and forms a stepped surface at the upper end of each lower flow path that narrows the flow path cross-sectional area.

The supply duct 11 includes a middle duct 16 that forms a hollow prismatic shape inside the beam 24 and extends vertically. The middle duct 16 has the same width as the second intermediate leg 25 in the width direction, and has a narrower width than the second intermediate leg 25 in the depth direction. The wiring receiving space k1 is formed on the outside of the middle duct 16 in the depth direction.

Inside the middle stage duct 16, a middle stage separator 17 connected above the separator 15 is arranged. The middle stage separator 17 partitions the internal space of the middle stage duct 16 in the depth direction, and forms the first middle stage flow path 17a and the second middle stage flow path 17b in the middle stage duct 16. The first middle stage flow path 17a is connected with the flow path cross-sectional area narrowed above the first lower flow path 15a, and the second middle stage flow path 17b narrows the flow path cross-sectional area above the second lower flow path 15b. It is connected.

The first blowout fin 38a and the second blowout fin 38b are supported on both sides of the upward extending portion 37c in the depth direction via a rotation shaft 38c along the width direction.

The blowout fin 38 includes a base portion 39a supported by the rotation shaft 38c, and a rotation portion 39b that is bent and connected to the base portion 39a in a width direction.
The blowout fin 38 may be in a laterally guided state in which the base portion 39a is substantially horizontal and the rotating portion 39b is tilted so as to be positioned downward as it is located closer to the corresponding unit top plate 21a in the depth direction (FIG. FIG. 6). At this time, the conditioned air A blown upward from the upper supply port 13 is guided downward and toward the corresponding unit top plate 21a along the inclination of the rotating portion 39b of the blowing fin 38 in the laterally guided state. The conditioned air A guided in this way reaches the upper surface of the top plate before reaching the user P facing the corresponding unit top plate 21a, and is gently supplied to the vicinity of the abdomen of the user P along the upper surface of the top plate. (Indicated by the solid arrow A in FIG. 3). This lateral induction state is suitable for heating.

The blowout fin 38 further rotates from the laterally guided state, tilts the base portion 39a so as to be positioned upward so as to be located on the corresponding unit top plate 21a side in the depth direction, and makes the rotating portion 39b substantially horizontal. The second lateral induction state can be achieved (see FIG. 7). At this time, the conditioned air A blown upward from the upper supply port 13 is guided substantially horizontally toward the corresponding unit top plate 21a along the rotating portion 39b of the blowing fin 38 in the second side-guided state. .. Specifically, the conditioned air A inclines slightly upward when leaving the rotating portion 39b of the blowout fin 38, and then flows while gradually changing downward. The conditioned air A guided in this way is supplied with a slight air flow to the vicinity of the face of the user P facing the corresponding unit top plate 21a (indicated by the chain line arrow A in FIG. 3). This second lateral induction state is suitable for cooling. That is, when it is desired to avoid cooling the abdomen during cooling, the air conditioning can be more effective for the user P by changing the state of the blowout fin 38 according to the situation.

The blowout fin 38 abuts the rotating portion 39b on the outer surface of the side wall of the blowout frame 36, and inclines the base portion 39a so as to be positioned upward so as to be located on the opposite side of the corresponding unit top plate 21a in the depth direction. It can be in an upward guidance state (see FIG. 8). At this time, the conditioned air A blown upward from the upper outlet is not guided to the corresponding unit top plate 21a side, and a gap formed between the base portion 39a and the upward extending portion 37c of the separator 37 in the frame is formed. It is blown upward. The conditioned air A blown upward from the gap is guided upward while avoiding the space 21k2 above the corresponding unit top plate 21a, and is not directly supplied to the user P facing the unit top plate 21a.

The side-guided state and the second side-guided state of the blowout fin 38 are states in which the upper supply port 13 guides the conditioned air A in the horizontal direction or the downward inclined direction, and is a state that can be taken in the second aspect. be. The upward guidance state of the blowout fin 38 is a state in which the supply duct 11 guides the conditioned air A upward, and is a state that can be obtained in the first aspect.

In this way, by selectively adjusting the supply of the harmonized air A from the upper supply port 13, it is possible to adjust the air conditioning environment according to the preference and physical condition of the individual user P.
Here, the upper supply port 13 (first upper supply port 13a and second upper supply port 13b) is substantially evenly divided into three in the width direction. The blowout fins 38 (first blowout fins 38a and second blowout fins 38b) correspond to the division of the upper supply port 13 and are substantially evenly divided into three in the width direction. Thereby, it is possible to change the supply of the conditioned air A to the individual user P also in the width direction.

With reference to FIG. 4, since the conditioned air A is heavy during cooling in summer, the conditioned air A is blown from the upper end position of the desktop panel 27 to the corresponding unit top plate 21a side with the blowout fin 38 in the second lateral guidance state. Then, the conditioned air A gently descends from the state of being inclined upward, and is gently supplied to the vicinity of the face of the user P. On the other hand, even if the conditioned air A is blown out from below the top plate, the conditioned air A descends to the floor surface F, so that it is difficult to supply the conditioned air A near the body of the user P.
Therefore, especially during cooling, the supply amount of the conditioned air A from the upper supply port 13 to the corresponding unit top plate 21a side is increased (the blowout fin 38 is set to the side induction state or the second side induction state), and the lower supply port. It is preferable to reduce or eliminate the amount of the conditioned intake air blown from the 12 (the opening / closing member 19 is set to the half-open state or the closed state). When the amount of the conditioned air blown out from the lower supply port 12 is reduced or eliminated, a large amount of the conditioned air A is guided to the upper supply port 13, so that the amount of the conditioned air A blown out from the upper supply port 13 can be increased.
At this time, even if the set temperature is high, the supply of the conditioned air A to the vicinity of the face makes it easy to feel a cool feeling. When the conditioned air A is blown out with the blowing fins 38 in the laterally guided state, the conditioned air A is supplied to the vicinity of the abdomen of the user P along the upper surface of the top plate to cool the abdomen.

With reference to FIG. 5, since the conditioned air A is light during heating in winter, even if the conditioned air A is blown from the upper end position of the desktop panel 27 to the corresponding unit top plate 21a side, the conditioned air A rises and is used. It is difficult to supply to the body of person P. On the other hand, when the conditioned air A is blown out from below the top plate, the conditioned air A rises to reach the lower surface of the top plate and is gently supplied to the body of the user P along the lower surface of the top plate.
Therefore, especially during heating, the supply amount of the conditioned air A from the upper supply port 13 is reduced (the blowout fin 38 is in the upward induction state), and the blowout amount of the conditioned intake air from the lower supply port 12 is increased (opening / closing member 19 is opened). It is good to be in a state). When the amount of conditioned air blown out from the upper supply port 13 is reduced, a large amount of conditioned air A is blown out from the lower supply port 12 due to the internal pressure of the supply duct 11, so that the amount of conditioned air A blown out from the lower supply port 12 is increased. be able to.
At this time, even if the set temperature is low, it is easy to feel the warmth by supplying the conditioned air A to the vicinity of the abdomen. When the conditioned air A is blown out with the blowing fin 38 in the laterally guided state, the conditioned air A is supplied to the vicinity of the abdomen of the user P along the upper surface of the top plate to warm the abdomen.

By making it possible to adjust the air conditioning for each seating position T in this way, it is possible to provide an air conditioning environment suitable for each seating person P without significantly raising or lowering the temperature setting of the entire room. That is, the conditioned air A that gives a feeling of coldness or warmth can be individually applied to each seated person P, and fresh air can be directly supplied to the seating position T. Therefore, it is easy to respond to the tastes of each user P such as heat and cold, improving comfort, making it easier for users P with different room temperature preferences to coexist in the same room, and further suppressing the air conditioning load (energy saving effect). Can be obtained).

In addition, since the amount and direction of the harmonious air A blown out can be adjusted from the seating position T for each air conditioning desk, the air conditioning can be easily operated and set according to the preference of the user P, and a sense of self-efficacy can be achieved. Can be enhanced. Further, since the conditioned air A can be supplied by utilizing both the air flow and the convection, the comfort can be further improved. Moreover, the intellectual productivity can be improved by realizing the air conditioning according to the preference of the user P.
