Abstract

PROBLEM TO BE SOLVED: To prevent an occurrence of a condensate and simplify a structure by having an open frame body provided with a flared outer cone portion, an intermediate cone disposed at an opening portion of the open frame body and being made of a flared blade body and an inner duct and making the inner and outer peripheral surfaces of the blade body and the inner duct heat-insulated from each other. SOLUTION: Cold air which enters a chamber 11 of an air inlet integrated-type blow-off device 1 from a blow-off duct reaches an open frame body 12 which is communicated with an opening portion at the bottom thereof and then is blow off into the inside of a room as primary air through an opening portion defined between an outer cone portion 12a and an intermediate cone portion 13.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction port which is arranged on a ceiling or the like in a space to be air-conditioned and which blows air-conditioning gas into the space and can suck air in the space. The present invention relates to an integrated outlet device.

[0002]

2. Description of the Related Art In recent years, air-conditioning blow-off devices for blowing conditioned air into a room have been equipped with a function of blowing a conditioned air and a function of sucking room air for ventilation. The device is being used.
FIG. 7 shows such a conventional suction port integrated type outlet apparatus. FIG. 7 is a schematic configuration explanatory view of a conventional suction port integrated type outlet apparatus.

[0003] In Fig. 7, the conventional suction-integrated blow-out device 100 is formed in a rectangular box-like body provided in a ceiling 70 and provided with a partition body 101a for partitioning the inside up and down. A duct 71 communicates with the lower internal space partitioned by the partition body 101a, and a suction duct 72
Is provided below the chamber 101, and one end of the chamber 101 is connected to the chamber 101.
01, an outer cone 102 communicating with the lower internal space and having the other end formed in an expanded shape in the blowing direction;
02, concentrically arranged at a predetermined interval inside, and one end side is connected to the partition body 101a inside the chamber 101, communicates with the upper internal space of the chamber 101, and the other end expands in the blowing direction. A middle cone 103 formed in
In this configuration, a dish-shaped center portion 104 is disposed concentrically at a predetermined interval inside the opening area of the cone 103.

[0004] In the conventional suction outlet integrated outlet device 100 having the above-described structure, the conditioned air supplied from the outlet duct 71 is supplied to the space between the outer cone 102 and the middle cone 103 through the lower internal space of the chamber 101. Blows out substantially horizontally as primary air A into the room. This conditioned air is generally cool air, and by blowing such cool air substantially horizontally along the middle cone 103, cold air heavier than room air is surely diffused from the ceiling side into the indoor space. On the other hand, the warm air in the room is attracted as secondary air B by the cool air of the blown primary air A, and rises and gathers near the middle cone 103. The secondary air B is supplied to the middle cone 103 and the center 1
The air is sucked in a substantially vertical direction from an opening portion between the suction pipe and the suction duct 72 and passes through the inside of the middle cone 103 and the upper internal space of the chamber 101 to the suction duct 72. Since the air outlet and the air inlet are separated from each other by a predetermined distance and the angle between the air outlet and the air intake is in an appropriate relationship, a short circuit does not occur, and the air conditioning in the room can be uniformly performed without bias.

[0005]

Since the conventional suction-integrated blow-out device is constructed as described above, the chamber 101 itself, the partition body 101a and the middle cone 103 are formed.
The structure such as the connection part with the is complicated, it takes time and effort to manufacture,
There was a problem that the cost would be high.

The chamber 101 and the middle cone 10
3 is cooled by the supplied cool air, and when the warm air in the room, which is attracted and sucked by the blown air flow, comes into contact with the inner cone 103 and the inner surface of the chamber 101, dew condensation easily occurs in these portions. However, there is a problem that the cost is further increased if an insulating material is internally applied to prevent the dew condensation.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and has a simplified inlet structure and a reduced cost while maintaining reliable short circuit prevention performance without dew condensation. The purpose is to provide.

[0008]

SUMMARY OF THE INVENTION An integrated suction port outlet device according to the present invention is formed of a substantially box-shaped hollow body, and has two substantially cylindrical neck portions for connecting ducts at side portions. A chamber having an opening at the bottom, and a substantially cylindrical body having one end communicating with the opening of the chamber and the other end facing a space to be air-conditioned. An opening frame body in which an outer cone portion that expands toward the blowing direction is formed around the opening on the other end side of the body, and one end portion is directed to the opening portion of the chamber, and the other end portion is the air conditioning object. A middle cone comprising one or a plurality of expanded blades disposed concentrically at a predetermined distance from the outer cone portion in the opening region of the opening frame toward the space side; and One end communicates with one neck and the other end is connected to one end of the middle cone. In an internal duct formed by communicating, outermost sail body and internal duct which is located closer in said cone, in which the inner peripheral surface side and the outer peripheral surface formed by a heat insulating state from one another. Thus, according to the present invention,
Since the inner peripheral surface side and the outer peripheral surface side of the blade body and the inner duct are insulated from each other, even if cool air flows along the outer peripheral surface of the blade body and the inner duct, the inner peripheral surface is not cooled, and the inner peripheral surface is not cooled. Even if warm air comes into contact with the surface, it does not cause condensation at all,
By connecting the middle cone and the suction duct via the internal duct, the structure can be simplified, the assembling work is facilitated, and the working efficiency can be improved.

[0009] Further, in the suction port integrated type blow-out device according to the present invention, the internal duct is a flexible duct of a flexible cylinder as required. As described above, according to the present invention, by connecting the middle cone and the suction duct through the flexible duct, the structure can be simplified and the weight can be reduced, the assembling work can be easily performed, and the chamber can be insulated. The work can be simplified, work efficiency can be improved, and the cost of the entire apparatus can be reduced.

[0010] In addition, in the suction port integrated type outlet device according to the present invention, if necessary, the blade body located at the outermost periphery of the middle cone may have the other end portion below the outer peripheral portion of the outer cone portion. It is formed to extend in the expanding direction. As described above, according to the present invention, with respect to the opening inside the middle cone facing the air-conditioning target space, the opening between the outside outer cone and the middle cone separates to the outer peripheral side by the length of the blade body, and By restricting the entry and exit directions to be almost horizontal, it becomes difficult for airflow to flow between the openings,
It is possible to prevent a phenomenon (short circuit) in which a part of the airflow that has exited one of the openings is sucked into the other as it is, so that efficient air conditioning can be performed with less waste.

Further, in the suction port integrated type outlet apparatus according to the present invention, if necessary, the blade located closest to the outer periphery of the middle cone may be bent in the substantially horizontal direction by bending the other end. It is formed so as to be close to the outer cone. As described above, according to the present invention, the opening portion between the outer cone portion and the middle cone outside the inner cone portion facing the air-conditioning target space makes the wing body at the outermost periphery of the middle cone substantially horizontally. By being formed narrower by the length of the extension and away from the outer peripheral side, especially when blowing cool air from the opening portion between the outer cone portion and the middle cone, the speed of blowing the airflow in the substantially horizontal direction by the narrowed portion is increased. As a result, the speed of the air flow is increased quickly, and the blown-out cool air is hardly recirculated to the middle cone side, and can be sent to the indoor space without waste, so that more effective air conditioning can be performed.

Further, in the suction port integrated type blow-off device according to the present invention, if necessary, the middle cone may have one end of the blade located closest to the outer periphery and the blade adjacent to the inner periphery of the blade. It is formed in a state in which a gap between one end of the body is closed. As described above, according to the present invention, the airflow cannot flow between the blade body located closest to the outer circumference of the middle cone and the blade body adjacent to the inner circumference side, so that the inside of the middle cone facing the air-conditioning target space can be prevented. In contrast to the substantial opening through which air can enter and exit, there is an opening between the outer cone and the middle cone with a predetermined space outside the opening, making it difficult for airflow to flow between the separated openings. The airflow that has flowed out of one of the openings can be reliably prevented from being sucked into the other as it is, and efficient air conditioning can be performed with less waste, and the blade body viewed from the air conditioning target space side There is no remarkable protrusion such as, and installation can be performed without being restricted by appearance.

Further, in the suction port integrated type blow-off device according to the present invention, if necessary, each of the blades of the middle cone is formed by extending the other end portion by a predetermined length in a direction substantially perpendicular to the opening surface. Is what is done. As described above, according to the present invention, the opening inside the middle cone moves away by the extension of each blade body with respect to the opening between the outer cone and the middle cone facing the air-conditioning target space, and the direction of air flow. By restricting the air flow in a direction perpendicular to the opening surface, it is possible to reliably prevent a phenomenon in which air flow is difficult to flow between the opening portions and the air flow exiting one opening portion is directly sucked into the other, It is possible to perform efficient air conditioning with less waste.

An opening frame 12 formed, and one or a plurality of expanded blades which are disposed concentrically in the opening region of the opening frame 12 at a predetermined interval from the outer cone portion 12a. And the suction side of the chamber 11 One end connected to click portion 11b,
A flexible duct 14 is provided as an internal duct having the other end connected to the upstream end of the middle cone 13.

The chamber 11 is provided with a blow-side neck 1.
1a is positioned higher than the suction side neck portion 11b, each is disposed on a different side surface, and a sheet-shaped heat insulating material is integrally disposed on each inner peripheral surface to form a hollow box made of a rectangular steel plate. The suction duct 71 is connected to the outlet neck 11a, the suction duct 72 is connected to the suction neck 11b, and the conditioned air supplied from the outlet duct 71 is taken in. From the opening at the bottom to the indoor space to be air-conditioned.

The opening frame 12 is disposed such that the lower portion of the outer cone portion 12a is exposed below the ceiling 70, and the conditioned air sent from the chamber 11 to one end is opened through the other end to the room. It is a configuration that blows out into space.

The middle cone 13 is formed integrally by disposing concentrically arranged outer blades 13a, inner blades 13b, and central blades 13c having different sizes and expanding directions. The configuration is such that it is disposed in the opening area of the opening frame 12 toward the side. On one end side of each wing body forming the middle cone 13, a support bracket 13 is formed by arranging three rectangular cross-section arms at equal intervals radially and integrating them at the center.
d is uniformly attached, and the end of each arm of the support bracket 13 d is fixed to the inner periphery of the opening frame 12 to fix the middle cone 13. In the middle cone 13, one end of each of the outer blade body 13a and the inner blade body 13b is formed to have a diameter adjacent to each other, is overlapped and closely attached without any gap, and is formed between the outer blade body 13a and the inner blade body 13b. The airflow cannot pass between them. Further, a neck portion 13e for connecting the end portion of the flexible duct 14 is provided at one end portion on the upstream side of the outer blade body 13a. Further, a sheet-like heat insulating material 13f having a predetermined thickness is disposed on the outer peripheral surface of the outer blade body 13a of the middle cone 13, and the outer peripheral surface of the neck portion 13e is subjected to flocked finishing. The inner peripheral surface side is substantially insulated from the outer peripheral surface side.

The flexible duct 14 is a well-known heat-insulating duct in which a flexible body made of a heat insulating material such as glass wool and an outer covering material such as an aluminum sheet is formed into a tubular shape, and one end side is a suction side neck portion of the chamber 11. 11b, and communicates with the suction duct 72.
3 and is connected to the inner peripheral side of the middle cone 13.

Next, a description will be given of the cold air blowing operation in the suction port integrated type outlet apparatus having the above-described structure. The cool air sent from the blowing duct 71 enters the chamber 11 and reaches the opening frame 12 communicating with the opening at the bottom.
While gradually flowing sideways along the outermost outer blade body 13a of the middle cone 13, the outer cone portion 12 is formed as primary air A.
The air is blown into the room substantially horizontally from the opening between the a and the middle cone 13. At this time, the warm air in the room is attracted as the secondary air B by the flow of the primary air A, and rises toward the middle cone 13. The secondary air B that has reached just below the middle cone 13 is sucked into the middle cone 13 from an inner peripheral opening of the inner blade body 13b of the middle cone 13 and passes through the flexible duct 14 through the neck portion 13e of the middle cone. , To the suction duct 72. Outer blade body 13a of middle cone 13
A heat insulating material 13f and the like are disposed on the outer peripheral surface of the flexible duct 14 and the outer duct 13a and the flexible duct 14 because heat conduction from the outer peripheral surface to the inner peripheral surface hardly occurs. 14 is not cooled and can maintain a state close to the room temperature. For this reason, even if warm room air as the secondary air B attracted and sucked comes into contact with the outer blade body 13a of the middle cone and the inner peripheral surface of the flexible duct 14, no dew condensation occurs.

An area between the outer blade body 13a and the inner blade body 13b of the middle cone 13 is a region through which airflow cannot pass, and a predetermined space is secured between the cool air outlet and the room air inlet through this part. Therefore, a phenomenon (short circuit) in which the airflow blown out sideways is not immediately spread into the room and is immediately sucked into the suction port does not occur, and a predetermined cooling capacity can be secured.

(Second Embodiment of the Present Invention) Hereinafter, a suction port integrated type outlet apparatus according to a second embodiment of the present invention will be described with reference to FIG. FIG. 2 is a schematic cross-sectional view of the configuration of the suction-integrated air outlet device according to the present embodiment.

Referring to FIG. 2, the suction-integrated blow-out device 2 according to the present embodiment comprises a chamber 21, an opening frame 22 and a middle cone 23 as in the first embodiment.
And the flexible duct 24 in common, with the difference that the suction side neck 11b is replaced by the outlet side neck 21a, and the outlet side neck 11a is replaced by the suction side neck 21b. This is a configuration in which warm air is blown out as a heating device.

Next, a description will be given of a warm air blowing operation in the suction port integrated type outlet apparatus having the above-described configuration. The warm air sent from the outlet duct 71 is supplied to the outlet side neck 21a.
Through the flexible duct 24 disposed in the chamber 21, and is blown downward into the room as primary air A from the opening on the inner periphery of the inner blade 23 b of the middle cone 23 through the neck 23 e. The warm air blown downward draws the cold air in the room as the secondary air, and generates an induced airflow. In particular, the indoor air near the ceiling 70 is drawn as secondary air B near the outer peripheral edge of the opening frame 22 with the blowing of the warm air of the primary air A. The cold secondary air B that has reached near the outer peripheral edge of the opening frame 22 is sucked from the opening between the outer cone portion 22a and the middle cone 23, and
Reaches the inside of the chamber 21 through a bottom portion to which one end of the suction port communicates, and is guided to the suction duct 72.

A heat insulating material 23f and the like are disposed on the outer peripheral surface of the outer blade body 23a of the middle cone 23 and the outer peripheral surface of the flexible duct 24 in the same manner as in the first embodiment, thereby moving from the outer peripheral surface side to the inner peripheral surface side. Is in a heat-insulating state in which heat conduction hardly occurs.
Is not cooled by the cold air in the room. Therefore, even if the warm air as the primary air A comes into contact with the outer blade 23a of the middle cone 23 and the inner peripheral surface of the flexible duct 24, no dew condensation occurs.

Further, similarly to the first embodiment, a region between the outer blade member 23a and the inner blade member 23b of the middle cone 23 is a region through which airflow cannot pass. Since a predetermined distance is secured from the suction port, a phenomenon (short circuit) in which the airflow blown downward does not spread into the room and is immediately sucked into the suction port does not occur, and a predetermined heating capacity can be ensured.

(Third Embodiment of the Present Invention) Hereinafter, a suction port integrated type outlet apparatus according to a third embodiment of the present invention will be described with reference to FIG. FIG. 3 is a cross-sectional view of a main part of the integrated suction port outlet apparatus according to the present embodiment.

Referring to FIG. 3, the suction-integrated blow-out device 3 according to the present embodiment includes a chamber (not shown), an opening frame 32, and a middle cone 33 as in the first embodiment. And a flexible duct 34 in common with the outer blade body 33 of the middle cone 33.
a and one end of the inner blade body 33b are formed apart from each other, and the other end of the outer blade body 33a is
Is formed so as to extend in the expanding direction to the outer peripheral edge of the outer cone portion 32a.

In the above-described configuration, the opening between the outer cone portion 32a and the middle cone 33 outside the inner opening facing the interior space corresponds to the extension of the outer blade body 33a. Further, since the airflow is further separated to the outer peripheral side and the direction of the airflow is regulated to be substantially horizontal, a part of the airflow that has exited one opening is not diffused into the room as in the first and second embodiments. Therefore, the air conditioning can be performed efficiently without being sucked into the other side as it is.

(Fourth Embodiment of the Present Invention) Hereinafter, a suction-integrated air outlet device according to a fourth embodiment of the present invention will be described with reference to FIG. FIG. 4 is a cross-sectional view of a main part of the suction port integrated type outlet device according to the present embodiment.

Referring to FIG. 4, the suction-integrated blow-out device 4 according to this embodiment includes a chamber (not shown), an opening frame 42, and a middle cone 43, as in the first embodiment. And a flexible duct 44 in common with the outer blade body 43 of the middle cone 43.
a and one end of the inner blade body 43b are formed apart from each other, and the other end of the outer blade body 43a is extended radially in a substantially horizontal direction to form an inner peripheral surface of the outer cone portion 42a of the opening frame 42. This is a configuration formed in a state of approaching.

In the above-described configuration, the opening between the outer cone portion 42a and the inner cone 43 outside the inner cone 43 facing the indoor space is different from the downward opening inside the inner cone 43 facing the room.
Since the outer blade body 43a is formed narrower by the extent that the outer blade body 43a extends substantially horizontally and further away from the outer peripheral side, as in the first to third embodiments, one of the airflows that has exited one of the openings is formed. The air conditioning can be efficiently performed without the part being sucked into the other part without diffusing into the room. In particular, when the cool air is blown out from the opening between the outer cone portion 42a and the middle cone 43, the narrower the opening, the faster the airflow is blown out in the horizontal direction, and the stronger the airflow is. It is difficult to return to the middle cone 43 side, and cool air can be sent into the indoor space without waste.

(Fifth Embodiment of the Present Invention) Hereinafter, a suction port integrated type outlet apparatus according to a fifth embodiment of the present invention will be described with reference to FIG. FIG. 5 is a cross-sectional view of a main part of a suction port integrated outlet device according to the present embodiment.

Referring to FIG. 5, the suction-integrated blow-out device 5 according to the present embodiment comprises a chamber (not shown), an opening frame 52, and a middle cone 53 as in the first embodiment. And a flexible duct 54 in common.
a and one end of the inner blade body 53b are formed apart from each other, and the other end of each of the outer blade body 53a, the inner blade body 53b and the center blade body 53c is connected to the opening surface of the opening frame body 52. This is a configuration in which a predetermined length is extended downward substantially vertically.

In the above-described configuration, the opening inside the middle cone 53 moves away from the opening between the outer cone 52a and the middle cone 53 facing the indoor space by an amount corresponding to the extension of each wing body, and the air flow. Since the direction of entry and exit is regulated in a substantially vertical direction, as in the first to fourth embodiments, a part of the airflow that has exited one opening does not diffuse into the room and is directly sucked into the other. It is possible to perform air conditioning efficiently without being rare.

In the suction port integrated type outlet apparatus according to the first to fifth embodiments, the outlet port and the suction port are fixed and used. The configuration in which warm air (warm room air) passes on the circumferential side and cool air (cool room air) passes on the outer circumferential side is common regardless of cooling and heating. Therefore, as shown in FIG. The air supply path and the intake path before and after the integrated air outlet device can be switched between cooling and heating in the middle of the system. During cooling, air is blown out from the cool air passage side and sucked in from the warm air passage side. It is also possible to use a configuration in which air is blown out from the warm air passage side and sucked in from the cool air passage side, and the air outlet and the air inlet are used interchangeably for cooling and heating. Performance Each optimum blowing pattern in cooling and heating is possible to be easily obtained without troublesome work, such as removable-replacement of duct intact.

Further, in the suction port integrated type blowout apparatus according to each of the first to fifth embodiments, the inner circumference side and the outer circumference side of the round-shaped blowout port are divided concentrically to perform suction or blowout. Although it is configured to perform the suction or the blow, the suction or the blow may be separately performed inside and outside of the rectangular outlet. Further, the line-type outlet may be divided into a plurality of regions, and suction or blow-out may be performed from each of the divided regions.

[0038]

As described above, according to the present invention, the inner peripheral surface and the outer peripheral surface of the blade body and the inner duct are insulated from each other, so that the cool air flows along the outer peripheral surface of the blade body and the inner duct. The inner peripheral surface is not cooled even if air flows, and dew condensation does not occur even if warm air comes in contact with the inner peripheral surface, and the connection between the middle cone and the suction duct is performed through the internal duct, This has the effect of simplifying the assembly, facilitating the assembling work and improving the work efficiency. Also,
In the present invention, by connecting the middle cone and the suction duct through the flexible duct, the structure can be simplified and the weight can be reduced, and the assembling work is facilitated.
There is an effect that the heat insulation work of the chamber can be simplified, the work efficiency can be improved, and the cost of the entire apparatus can be reduced. Further, in the present invention, with respect to the opening portion inside the middle cone facing the air-conditioning target space, the opening portion between the outside outer cone portion and the middle cone separates to the outer peripheral side by the length of the blade body, and the air flow in and out. By restricting the direction almost horizontally, it is difficult for airflow to flow between the openings, and it is possible to prevent a phenomenon (short circuit) in which part of the airflow that has exited one opening is sucked into the other as it is. Thus, there is an effect that efficient air conditioning can be performed with less waste. Further, in the present invention, for the opening inside the middle cone facing the air conditioning target space, the opening between the outside outer cone and the middle cone extends the blade outermost outer periphery of the middle cone substantially horizontally. By being formed narrower and farther to the outer peripheral side, especially when blowing cool air from the opening between the outer cone portion and the middle cone, the speed of blowing the airflow in the substantially horizontal direction by the narrowed portion is increased. Since the momentum of the airflow is increased, the blown-out cool air is less likely to return to the middle cone side, and can be sent to the indoor space without waste, so that more effective air conditioning can be achieved. In the present invention, the air inside the middle cone facing the air-conditioning target space can be prevented because airflow cannot flow between the blade located closest to the outer periphery of the middle cone and the blade adjacent to the inner periphery thereof. For the substantial opening that can enter and exit, the opening between the outer cone portion and the middle cone exists with a predetermined space on the outside, and it becomes difficult for airflow to flow between the separated opening portions. It is possible to reliably prevent a phenomenon in which the airflow that has exited one opening is directly sucked into the other, and it is possible to perform efficient air conditioning with less waste, and to see the blades and the like as viewed from the air conditioning target space side. There is no significant protrusion, and there is an effect that installation can be performed without being restricted by appearance. Also, in the present invention, the opening inside the middle cone is separated by the extension of each blade body and the direction of the air flow is opened and closed with respect to the opening between the outer cone and the middle cone facing the air conditioning target space. By restricting in a direction perpendicular to the plane, it is difficult for airflow to flow between the openings, and it is possible to reliably prevent the airflow that has exited one opening from being sucked into the other as it is, and waste is eliminated. There is an effect that less efficient air conditioning can be performed.
