Description

[Detailed Description of the Invention] The present invention relates to an improvement of an air conditioner installed inside a ceiling.

Conventionally, this type of air conditioner has been constructed as shown in FIG. In the figure, 1 is a box-shaped main body, 2 is a ceiling exposed panel having an air inlet 3 and an air outlet 4 on the other side as shown in FIG.
is a filter provided above the suction port 3, 6 is a louver device provided at the blowout port 4 and adjusts the direction of the blown air, 7 is a filter case that houses the filter 5, 8 is a blower having a Shirotsuko fan, and 9 is a A heat exchanger, 10 is a dew pan for collecting condensed water of the heat exchanger 9, 11 is a partition plate attached to one end of the base plate of the blower 8, and the main body 1 is connected to the base plate of the blower 8.
The interior is divided into a suction side passage 23 and an outlet side passage 24. 12 is a drain outlet of the dew pan 10;
Reference numerals 13 and 14 designate pipe connection ports for connecting an inlet side pipe and an outlet side pipe (not shown) for supplying cold water or hot water to the heat exchanger 9. 15 is the outlet of the air outlet side passage 24 of the main body 1 and the exposed ceiling panel 2
A blow-off duct communicates with the blow-off port 4 of the main body 1 and is attached to the outlet of the blow-off side passage 24 formed by the partition plate 11 and the main body 1 so as to be slidable in the vertical direction via a sealing material 18.

Reference numeral 16 denotes a frame body for mounting the above-mentioned blow-off duct 15 and filter case 7, and is fixed to the main body 1 with a long screw 25 so as to be vertically adjustable as shown in FIG. A heat insulating material 17 is provided on the exposed ceiling panel 2 and forms a passage for the air outlet 4, and also serves as a seal between the frame 16 and the exposed ceiling panel 2. Incidentally, the exposed ceiling panel 2 is secured to the frame 16 by panel mounting screws 26. 19
is a heat insulating material affixed to the inner wall of the outlet side passage 24,
20 is a mounting piece provided on both sides of the main body 1; 21;
is a hanging bolt embedded in the ceiling slab B, and by inserting this bolt into a mounting piece 20 and tightening a nut 22, the hanging height of the main body 1 in the ceiling A is adjusted.

Next, the operation will be explained. By operating the blower 8, indoor air flows into the main body 1 from the suction port 3 via the filter 5, exchanges heat with the heat exchanger 9, becomes cold air or warm air, and then flows into the blower duct 15.
The air is blown out from the air outlet 4 into the room again through the air.
In addition, during installation work, since the blow-off duct 15 and frame 16 have a structure that allows them to slide up and down relative to the main body 1, the hanging height of the main body 1 can be adjusted to any position within the slidable dimensions. Because of this, advanced installation work is not required.

Since the conventional one is constructed as described above, the seal between the frame body 16 and the exposed ceiling panel 2 is particularly important when the exposed ceiling panel 2 is long, so that the central part of the exposed ceiling panel 2 is sealed with the heat insulating material 17. The compressive force causes the seal to bend and create a gap, which eliminates the sealing effect. That is, during cooling operation, cold air leaks from the above-mentioned gap, and the exposed ceiling panel 2 is cooled, making it easy for dew to form on the exposed ceiling panel 2. Further, since the heat insulating material 17 is bonded to the exposed ceiling panel 2 using an adhesive or the like, it is easily peeled off, and the structure is complicated, making it expensive.

This idea was made in order to eliminate the drawbacks of the conventional ones as mentioned above.By integrally molding the blowout duct and the insulation material with foamed resin, there are no problems such as cold air leakage or insulation material peeling. The aim is to provide air conditioners with improved practicality.

An embodiment of this invention will be described below based on the drawings.

In FIG. 4, reference numeral 27 denotes an air outlet duct, 28 a metal fitting for fixing the side of the air outlet duct 27 to the exposed ceiling panel 2, and 29 a mounting screw thereof. Further, one side of the blow-off duct 27 is fixed by being pressed at one end of the side plate of the filter case 7.
Further, the filter case 7 is directly attached to the ceiling exposed panel 2 with attachment screws 30, as shown in FIG. Ceiling exposure panel 2 with filter case 7 and air outlet duct 27 attached in this way
is fixed to the main body 1 so as to be vertically adjustable by inserting a long screw 31 into the exposed ceiling panel 2 and engaging a nut 32 welded to the main body 1.

In addition, on the piping connection ports 13 and 14 side of the main body 1,
Since an inspection port 33 is required to inspect the inside of the ceiling from inside the room, the ceiling exposed panel 2 has a length extending from the main body 1 by the space of the inspection port 33, as shown in FIG. However, the air outlet 4
The extension on the inspection space side needs to look similar to the air outlet 4 in terms of design, and needs to be closed so that the inside of the ceiling cannot be seen directly from inside the room. A support 34 made of foamed resin is provided for the above purpose, and a blowout duct 27 is provided at both ends of the support 34.
A step is provided at the end of the holder so that it can be press-fitted.

When installing the air conditioner configured in this way, the installation position is the hanging bolt 21 in the ceiling A.
This is done using the nuts 22, but since the exposed ceiling panel 2 is installed in contact with the lower surface of the ceiling A as shown in Fig. 4, the adjustment screws 31 are tightened or loosened depending on the height within the ceiling A. It can be adjusted by At this time, the air outlet duct 27 also moves together with the exposed ceiling panel 2, but the sealing material 18
Thus, the seal with the outlet of the blow-out side passage 24 is maintained.

The above is the same as the conventional one, but since the blow-off duct 27 has a structure in which it is integrally molded with foamed resin and is installed from the outlet of the blow-off side passage 24 of the main body 1 to the blow-off port 4 of the ceiling exposed panel 2, it is different from the conventional one. As there is no joint between the main body 1 side and the ceiling exposed panel 2 side, and therefore no sealing part, the ceiling exposed panel 2 will not be deformed by the compressive stress of the sealing member, and there is no fear of cold air leakage. do not have. Also,
Inspection port 33 provided on the piping connection ports 13 and 14 side
A support 34 is provided at the extension of the air outlet 4 in the space, and the end of the support 34 is fitted onto the air outlet duct 27 and fixed by pressing, so that there is a gap between the air outlet duct 27 and the support 34 due to dimensional errors, etc. Even if this occurs, the inside of the ceiling cannot be directly seen from inside the room due to the level difference in the fitting, and air circulation is also difficult to occur due to the labyrinth effect. Also, in terms of design, the shape is an extension of the four air outlets, and all of them are painted black, so there is no problem at all. Furthermore, if the pipe connection ports 13 and 14 of the main body 1 are in the opposite direction, the inspection port 33 will also be located on the opposite side to that shown in FIGS. 5 and 6, but in that case, the ceiling exposed panel 2
It is only necessary to extend the frame body to the opposite side and reverse the positional relationship between the blow-off duct 27 and the support 34.

As described above, in this design, the air passage from the outlet of the air passageway to the air outlet of the exposed ceiling panel is integrally molded with an air outlet duct made of foam resin molding, so that the air passage inside the air outlet of the exposed ceiling panel There is no need to provide a separate heat insulating material, and there is no joint between the lower part of the main body and the exposed ceiling panel, so there is no sealing part in this area, so the exposed ceiling panel will bend due to the compressive stress of the sealing member. Solve the problem of cold air leaking from gaps. Furthermore, a support made of foamed resin molded with a step that fits and presses on both ends of the air outlet extension corresponding to the extension of the inspection opening space of the exposed ceiling panel is provided, and the fitting part is connected to the air outlet duct. Since the structure is such that the support is fitted and pressed, there is no need for a special device to fix the support, and since the shape is an extension of the air outlet shape, there is no problem in terms of design. Furthermore, when manufacturing a device with reverse piping connection direction, it is only necessary to reverse the positional relationship between the blow-off duct and the support, so it is possible to provide an extremely practical device.
