[0002]
[Prior art]
The air conditioner blow-out unit is an opening used for blowing air from the air conditioner into the room or exhausting air in the room, and is mainly provided on the ceiling of a room where air conditioning is performed. These air-conditioning outlet units have various shapes depending on the position of the ceiling with respect to the room. For example, a round or square air-conditioning outlet unit is used on the ceiling surface in the center of the room. Among these, the line slit blowout unit has an elongated rectangular line slit-like blower outlet and is frequently used along the wall of the chamber. FIG. 4 is a perspective view of a conventional line slit blowing unit as viewed from below. The blow-out unit 110 includes a chamber 101 having a duct hole 105 connected to a duct through which air passes and a grill 102 attached to a lower portion of the chamber as main components. The chamber 101 is normally held by a suspension bolt 103 fixed to the ceiling slab 112, and its lower end is positioned higher than the ceiling plate 111 by an amount corresponding to the grill. An opening 107 is opened in the lower part of the chamber, and the upper end of the grill 102 is inserted into the opening 107. With such a structure, the line slit 106 serves as an outlet, and air from the duct is sent to the air-conditioned room, and the room air is sucked as an exhaust port.

[Problems to be solved by the invention]
However, since the line slit blowout unit has a long and narrow shape, the attachment to the ceiling is more troublesome than other shapes of airconditioning blowout units. Further, since the vertical movement of the entire blowing unit cannot be adjusted at the initial stage of installation of the blowing unit, the lower surface of the chamber is disposed above the ceiling plate by an amount corresponding to the grill. For this reason, it was not easy to attach a grill to the lower end of the chamber after confirming airtightness. Under such circumstances, it has been desired by a contractor to facilitate the installation of the line slit blowing unit. If there is a line slit blowout unit that satisfies both of the following three functions, the above-mentioned deficiencies will be corrected and installation will be very easy, but so far the line slit blowout unit has the following three functions. There is nothing.
(1) The lower end of the chamber can be lowered 5 to 10 mm below the planned ceiling surface. The air-conditioning blowout unit is not limited to the line slit type, and is installed when a building is newly constructed. At that time, if the above-mentioned matters are made, it is very convenient in construction for the above-mentioned reason.
(2) After connecting the grille to the chamber, the connecting part can be visually observed. If this visual observation is possible, the airtightness of the interface between the grille and the chamber can be confirmed.
(3) The unit composed of the grill and the chamber can be moved up and down without removing the grill from the chamber. With this function, the grill is attached to the lower surface of the chamber at the position (1), the visual confirmation of (2) is performed, and it is pulled up to the normal position, that is, the position where the lower end of the grill touches the lower surface of the ceiling plate. be able to.
[0004]
Then, an object of this invention is to provide the line slit blowing unit which has the structure which makes attachment construction easy and reliable, and its attachment method. Specifically, it aims at providing the line slit blowing unit provided with all the functions of said 3 items, and its attachment method.
[0005]
[Means for Solving the Problems]
The line slit blowout unit according to the first aspect of the present invention is a line slit blowout unit having an elongated shape exposed downward from the ceiling plate. The line slit blowing unit includes two suspension bolts fixed above the ceiling plate at positions corresponding to both ends of the elongated exposed portion, a chamber held by a nut screwed into the suspension bolt from below, and a blower. A grille having a decorative plate disposed around the outlet, each opening located at both ends and a center of the elongated exposed portion so as to be surrounded by the decorative plate, and a decorative lid that covers these openings Ru equipped with. The above grille is mounted on the lower surface of the chamber by screwing at a position corresponding to a total of three openings, that is, the opening at the center and the openings at both ends when viewed in plan. to through apertures of both ends, the chamber and grill as is screwed into the hanging bolt nuts visible configured, by changing the position of a nut screwed into the hanger bolts with lug wrench from the opening, wherein The mounting height of the chamber can be adjusted (Claim 1).
[0006]
With the above configuration, the suspension tool can be fixed to a ceiling slab, which is a fixing portion of the suspension tool, and the chamber can be held during building work, and the lower end surface of the chamber can be made lower than the planned height of the ceiling plate. For this reason, it becomes easy to attach a grill to the lower part of a chamber. In addition, even after the grill is attached to the chamber, the chamber mounting height is adjusted from below, and the mounting interface between the chamber and the grill is lowered below the ceiling plate to ensure that the mounting is complete or airtight. It can be easily confirmed whether or not. In addition, as said holding member, a long suspension bolt and a nut can be used. That is, a long bolt in a suspended state that is fixed to the ceiling slab is passed through a hole formed in the chamber, and the nut can be screwed into the long bolt to fasten the chamber to the suspension bolt. When the holding member has the above-described configuration, the nut can be adjusted without difficulty using a box wrench or the like with a small force. By providing the decorative lid as described above, the opening is closed, and an appearance that matches the tone of the air-conditioned room can be secured. For example, when the above-described suspension bolts are respectively disposed at both ends in the longitudinal direction of the line slit, the above-described lids are disposed at both ends. Further, the lid has an action of concealing the mounting portion when the mounting portion of the grille to the chamber is in the opening. In addition, since the decorative cover covers the mounting portion for attaching the grill to the chamber, even if the mounting portion of the grill to the chamber is in a position unrelated to the opening, the mounting portion is not viewed from below, and is subject to air conditioning. An appearance that matches the tone of the room can be secured. In addition, the grill is screwed to the chamber at three locations, the central portion and both end portions, in order to improve the airtightness of the connection between the grille and the chamber and to improve the airtightness with three openings. Easily done through. Furthermore, changing the screwing position of the nut with a box wrench, etc. allows the small opening and the decorative lid covering it to be easily removed. Insert the box wrench from the small opening to the chamber and insert the nut through the opening. You can easily adjust the height position while watching. In the above, it is important that the shape of the elongated exposed portion is a line slit shape. Because of its elongate shape, for example, it is not possible to easily insert a hand up to the chamber, and therefore it is possible to adjust the height only after inserting a box wrench into the openings at both ends.
[0011]
Above the line slit blowout units of the first aspect, by adjusting the mounting height of the chamber can be positioned at least 5mm below the lower surface of the ceiling plate to the lower surface of the chamber (claim 2).
[0012]
With this configuration, the air conditioner can lower the lower surface of the chamber by at least 5 mm from the planned construction height of the ceiling plate after fixing the holding member to the frame ceiling slab constructed by the contractor. For this reason, the mounting construction which attaches a grill to the said chamber lower end can be performed easily. In addition, the lower end part of a holder or a long volt | bolt cannot protrude below from a ceiling board. Therefore, as a matter of course, the length of the holder or the long bolt has an upper limit to satisfy this condition.
[0013]
The method for mounting the line slit outlet unit according to the first aspect of the present invention is a method for mounting the line slit outlet unit having an elongated shape exposed downward from the ceiling plate. In this mounting method , nuts are screwed onto two suspension bolts fixed above the ceiling plate corresponding to both ends of the elongated exposed portion so that the lower surface of the chamber is positioned below the lower surface of the ceiling plate. The process of attaching the chamber and the grill, which is a line slit-shaped air outlet member, on the lower surface of the chamber in a plan view, at positions corresponding to a total of three openings, the opening at the center and the openings at both ends. A step of fastening each screw and attaching, and a step of configuring the chamber and the grill before the attaching step so that the nut screwed to the suspension bolt after the attaching step can be seen from below through the openings at both ends; by changing the position of the nut to be screwed to the hanger bolts through an opening bored in both end portions of the decorative plate surrounding the air outlet grille lower surface by box wrench, the chamber mounting height Adjust the overhanging portion of the grill lower surface and a step of pulling the generally contact height in the ceiling plate lower surface (claim 3).
[0014]
By this method, it is possible to fix the holding member to the ceiling slab or the like before construction of the ceiling plate, and to attach the holding member so that the lower surface of the chamber is located below the lower surface of the ceiling plate (planned). Next, after the ceiling plate is formed, the grill can be attached to the chamber while confirming that the end faces are in an airtight state. Thereafter, the mounting height of the chamber mounting portion to the holding member is adjusted using a box wrench or the like through the opening from below and pulled up to a normal position. This mounting method is epoch-making compared to the conventional case, and airtight reliability is guaranteed.
[0015]
Above the mounting method of the first aspect, further includes a step of attaching the decorative lid in an opening bored in veneer grille lower surface (claim 4).
[0016]
With this configuration, the air outlet unit can be harmonized with the tone of the room.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
[0018]
FIG. 1 is a perspective view showing a line slit blowing unit according to an embodiment of the present invention. The line slit blowing unit 10 includes the chamber 1 and the grill 2 as its main constituent members. A chamber 1 having a duct hole 5 connected to a duct (not shown) is supported by two suspension bolts 3 fixed to a ceiling slab 12, and a grill 2 is attached to the lower surface thereof. The grill 2 is provided with an air outlet 6 on the lower surface, and air supplied from a duct is blown out from the air outlet, and air is sometimes sucked in from here for exhaust. The ceiling plate 11 surrounds the lower surface of the grill, but decorative plates 7a, 7b, 7c are arranged on the lower surface of the duct, and these decorative plates project outward at the end of the lower surface of the grill. For this reason, the clearance gap between a grill side and a ceiling board edge part is made invisible from the downward direction by the overhang | projection part of this decorative board. In FIG. 1, there are three types of decorative plates: a decorative cover 7a at the end in the longitudinal direction, a central decorative cover 7b, and a side decorative plate 7c. Among these, the decorative cover 7a at the longitudinal end and the center The decorative cover 7b is removable.
[0019]
Next, the structure of the above-described line slit blowing unit will be described in detail while explaining the attachment procedure. FIGS. 2A to 2C are cross-sectional views showing a procedure when the line slit blowing unit shown in FIG. 1 is attached to the ceiling. First, FIG. 2A is a cross-sectional view showing a state in which the chamber 1 is attached to the suspension bolt 3 fixed to the ceiling slab 12 and is suspended. (Strictly speaking, FIG. 2 (a) is a cross-sectional view of the stage where the ceiling is formed after the chamber is installed.) The line slit blowing unit has an elongated shape, and therefore stability is important. Then, the number of the suspension bolts 3 is two, and each of the two suspension bolts is arranged one at each end of the chamber. Any method may be used for attaching the chamber to the suspension bolt. When importance is attached to simplicity, for example, as shown in FIG. 2 (a), a threaded suspension bolt is passed through a mounting hole formed in the chamber mounting portion, and the nut 3a is screwed onto the screw. And fix. The chamber is suspended by an air conditioner. At the stage where the chamber 1 is suspended from the suspension bolt, the ceiling plate 11 is not provided. The ceiling board 11 is arrange | positioned by the contractor so that this blowing unit may be surrounded. If the lower surface of the chamber is at a higher position than the ceiling plate 11 at the stage where the ceiling plate 11 is disposed, the grill 2 cannot be attached smoothly. For this reason, the screw 3a screwed to the suspension bolt is adjusted so that the lower end of the chamber is at a position lower by about 5 mm to 10 mm than the lower surface of the ceiling plate. In FIG. 2A, the nut 3a is located at the forefront of the suspension bolt. At the position of such a nut, as viewed from the side, the length from "the height position of the interface between the fixing part and the exposed part of the suspension bolt" to "the height position one nut above the tip of the suspension bolt" Is l ₁ . The length from “the height position of the portion of the chamber in contact with the nut regardless of the position of the nut” to “the height position of the lower surface of the chamber” is l ₂ . Further, the length from “the height position of the interface between the fixing portion / exposed portion of the suspension bolt” to “the height position of the lower surface of the ceiling plate” is l ₃ . In order to make the lower end of the chamber lower by about 5 mm to 10 mm than the lower surface of the ceiling plate, for example, l ₁ + l ₂ may be 5 mm to 10 mm longer than l ₃ at the position of the nut. However, determining the overall configuration by measuring the length of each part of the member in this way may not be able to achieve the purpose due to insufficient accuracy due to ambiguity of measurement error and measurement position of the member. Therefore, the overall configuration based on the measurement of each of the above parts is only a reference example. Actually, while configuring the entire line slit blowout unit, adjust the dimensions of each part, especially the suspension bolt dimensions, and confirm that the lower end of the chamber can be positioned about 5 mm to 10 mm lower than the lower surface of the ceiling plate, and determine the final structure Is desirable.
[0020]
Next, FIG.2 (b) is sectional drawing of the stage which attached the grille 2 to the chamber of the state of FIG. The lower surface of the chamber and the upper surface of the grill have substantially the same shape when seen in a plan view. For this reason, the attachment of the grill 2 to the chamber 1 is performed by abutting and bolting. Although not shown in FIG. 2B, a female screw is cut at the lower end of the chamber 1, and a male screw 15 inserted from the lower side of the grill is screwed into this female screw and screwed. This screwing is performed at three locations, that is, the central opening 23 and the two end openings 22b in the longitudinal direction of the line slit. At the time of this screwing, as shown in FIG. 2 (b), since it is not yet covered with the decorative lid, it can be easily screwed from below. In the state of FIG. 2 (b), the position of the suspension bolt and nut supporting the chamber can be easily seen from below because the opening 22a is not yet covered with a decorative lid. Since the position of the chamber in FIG. 2 (b) is the same position as in FIG. 2 (a), when the grill 2 is attached, the position of the grill is naturally lower than the normal position.
[0021]
FIG.2 (c) is sectional drawing of the state which pulled up the whole blowing unit and was pulled up to the position where a grill lower surface contact | connects a ceiling board. In this pulling up, a box wrench is inserted from the opening 22a at both ends of the lower surface of the grill and the opening 21 at the portion where the chamber and the grill are in contact, and the nut 3a is grasped and rotated to pull up the entire blowing unit. This operation can be easily performed using a box wrench. Needless to say, it is checked whether or not the joining of the chamber and the grill ensures airtightness before the lifting. At the stage where the lifting is finished, the decorative lids 7a and 7b are respectively attached to the openings 22a and 22b at both ends and the opening 23 at the center, so that the color tone matches the tone of the air-conditioned room. For example, when air conditioned is blown out, as shown in FIG. 2 (c), the air supplied from a duct (not shown) passes through the opening 9 at the portion where the chamber and the grill come into contact with the grill. And is supplied into the room through the line slit 6 which is the opening of the grill. As is clear from FIG. 2 (c), the lower end portion of the holder or the long bolt cannot protrude downward from the ceiling plate. Therefore, for the suspension bolt, the above (l ₁ + the length of one bolt) is shorter than the above l ₃ .
[0022]
FIG. 3A is a longitudinal sectional view of the grill, and FIG. 3B shows the bottom of the grill, that is, the surface seen from the room. In FIG. 3A, the screw guide portion 25 and the opening 21 at the end are made invisible from the room by the decorative lid 7a and the screw guide portion 25 at the central portion by the decorative lid 7b.
[0023]
With this configuration, the line slit blowing unit can be easily and reliably installed and can be harmonized with the tone of the room.
[0024]
