Description

  The present invention relates to a branched chamber used in an air conditioner.

  Conventionally, in the piping of an air conditioner installed in the back of a ceiling or the like, a connection as shown in FIG. 8 has been performed in order to guide the air from the air conditioner side to the air outlet that leads to the room. In the air conditioning piping shown in FIG. 8, between the main duct 70 and the outlet 75, the duct 71 is sequentially branched in two directions using the branch pipe 72, and air from the air conditioner (main body) side is drawn. , And led to the outlet 75.

In order to make it easier to perform the air conditioning piping as described above, connection as shown in FIG. 9 is performed. In the air conditioning piping shown in FIG. 9, a chamber 80 is disposed between the main duct 70 and the plurality of outlets 75, and air from the air conditioner side is introduced into the chamber 80, and the introduced air is supplied to the chamber 80. Are branched and discharged from a plurality of discharge ports 82, and led to a blow-out port 75 through a duct 73.
As shown in FIG. 7, the chamber 80 has a rectangular parallelepiped box shape, and a single inlet 81 for introducing air from the air conditioner side into the side wall of the chamber 80 (in the short side portion of the rectangular parallelepiped planar shape). And a plurality of discharge ports 82 (located at the long sides of the rectangular parallelepiped plane) for branching out and discharging the introduced air.
The chamber 80 enables intensive branch connection, and piping work can be easily performed.

  For example, Patent Document 1 includes “a hollow box including a side wall having a communication hole, and a connection duct that passes through the communication hole and can be pushed into the hollow box and moved freely. An air-conditioning chamber device in which the hollow box body and the connection duct are provided with a joint lock portion that allows the connection duct to communicate with the hollow box body in an airtight manner while the connection duct is pulled out to hold the joint. (Refer to claim 1 and FIGS. 1 to 4), and this chamber apparatus is premised on the above-described concentrated branch connection.

  In addition, as related to the application of the present applicant, Patent Document 2 states that “one inlet for introducing air from the air conditioner side, and the introduced air are branched into the side wall of the box-shaped chamber body.

As shown in FIG. 7, in the chamber 80 in the above-described prior art, all the discharge ports 82 (outlets) provided in the chamber main body are arranged in a line at the same level (horizontal level). Therefore, as the number of branches increases and the number of outlets increases, the chamber body extends in the horizontal direction and becomes larger (D in FIG. 7). Further, since the diameter of the inlet 81 (inlet) increases as the number of branches increases, the height (H) of the chamber body also increases. Therefore, the weight of the chamber body is increased, the workability during construction is reduced, and the material and processing costs for manufacturing are increased due to the increase in size of the chamber itself.
The present invention relates to a branched chamber used for the air conditioning piping as described above, realizing a reduction in the size of the chamber body, reducing the weight by reducing the size of the chamber, and improving workability during construction. The purpose is to reduce material costs and processing costs by reducing the size of the chamber, and to achieve excellent air volume balance performance.

(1) In the present invention, a box-shaped chamber body is provided with one inlet for introducing air from the air conditioner side and a plurality of outlets for branching and discharging the introduced air. The branched chamber for an air conditioner is provided with a plurality of outlets arranged in a vertical direction (up and down direction) in a side view.
(2) One preferable embodiment is one provided with discharge ports arranged in a staggered manner in a side view.
(3) In one preferred embodiment, the discharge ports are arranged such that the discharge ports in each stage are arranged in a plan view and a radial shape, respectively.
(4) The chamber body is preferably formed in a cylindrical shape.

(1) Since the present invention includes a plurality of upper and lower discharge ports as viewed from the side, even if the number of branches increases and the number of discharge ports increases, the horizontal extension of the chamber body is reduced. Therefore, the chamber body can be downsized. In the conventional chamber, wasteful material spaces are generated above and below the discharge ports arranged in a line on the side surface of the chamber body, but this is effectively utilized. It is possible to reduce the weight of the chamber by reducing the size of the chamber and to improve workability during construction. Moreover, material costs and processing costs can be reduced by downsizing the chamber.
(2) By providing discharge ports arranged in a staggered manner in a side view, in addition to the horizontal extension of the chamber body, the size of the chamber body can be suppressed by suppressing the size of the chamber body in the height direction. Miniaturization can be realized with a good balance.
(3) As for the discharge port, the discharge ports at the respective stages are arranged in a plan view and a radial shape, so that the duct can be suspended from the discharge port to the terminal outlet in a substantially linear state. Therefore, it is easy to construct and the length of the duct can be shortened and the bending of the duct can be reduced. Therefore, a difference in duct resistance is unlikely to occur, and excellent air volume balance performance by the chamber can be maintained.
In particular, in the case of the one provided with the discharge ports arranged in a zigzag shape in a side view, the direction in which the discharge ports face is greatly increased, so that the shortest connection to the terminal outlet can be smoothly performed.
(4) Since the chamber body is formed in a cylindrical shape, an existing large-diameter air conditioning duct can be used as a side wall of the chamber body, and the manufacturing cost can be greatly reduced. . Moreover, uniform air volume balance performance can be exhibited by the plenum effect (filling effect) in the cylindrical body which can be formed small.

A sound absorbing / insulating material may be applied to the inner surface of the chamber body 10, particularly the inner surface of the side wall 11. The sound absorbing / insulating material is made of a nonflammable material such as glass wool, rock wool, or ceramic wool. Preferably, in order to prevent scattering and falling off of the fibers of the sound absorbing / insulating material, a film formed by coating a black resin or the like on the innermost surface is used. In addition, a hanging metal fitting is appropriately provided on the upper periphery of the chamber main body and used for hanging during construction (not shown).

  When the introduction port 20 and the plurality of discharge ports 31, 32, ..., 36 are formed in a cylindrical shape, these materials are not particularly limited, but a metal material such as a zinc steel plate is preferably used. . A well-known pipe joint can be utilized.
