Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a ceiling-mounted air conditioner such as a ceiling-suspended type or a ceiling-embedded type, and particularly relates to the mounting structure of a blower and related components.

(Prior Art) In a ceiling-mounted air conditioner, it is necessary to set the structure in consideration of maintenance, as disclosed in, for example, Japanese Utility Model Publication No. 56-37215. Generally, the blower, motor, heat exchanger, etc. are the main objects of maintenance, so the placement of these devices is particularly important.

Incidentally, in conventional air conditioners, the discharge port 7a of the blower 7 is usually screwed to the duct 5 via a sealing flange 5a, as shown in FIG. Further, the rotor 9 of the blower 7 is directly connected to the output shaft 8a of the motor 8, so that the blower 7 and the motor 8 are substantially integrated. Reference numeral 6 in the figure is a heat exchanger.

(Problem to be solved by the invention) In the above structure, for example, when replacing the motor 8, remove the screw screwed into the boss 9a of the rotor 9 from the service space S1 side facing the blower 7, and then replace the motor 8. It is necessary to remove the motor 8 from the service space S2 side facing the motor 8. In addition, in order to separate and take out the blower 7 from the duct 5, the discharge port 7
It is necessary to remove the fixing screws surrounding a. As described above, conventional air conditioners have problems in that maintenance work is troublesome and service spaces are required on both sides of the air conditioner. Note that, depending on the air conditioner, the blower 7 may be fixed to the passage upstream of the heat exchanger 6, but this case also has the same problem as described above.

This idea was made in view of the above-mentioned problems, and allows maintenance work to be easily performed in a ceiling air conditioner that is equipped with a blower and a motor that drives it, each of which needs to be fixedly supported. Furthermore, the purpose is to provide an excellent space-saving feature in which the service space is only required on one side.

(Means for Solving the Problems) The root cause of the above problems lies in the fact that the blower and the motor are individually fixed to the casing of the air conditioner. Therefore, in this invention, as shown in FIGS. 1 and 2, a mounting plate 10 is provided in the casing 1 that can be inserted and removed, and the blower 7 is fixed to the mounting plate 10, and the blower 7 and the motor 8 are These are placed integrally and made slidable to form a single unit, which is then fixed with screws or the like on the service space side provided on one side of the casing 1. That is, a heat exchanger 6, a blower 7, and a motor 8 for rotationally driving the blower 7 are arranged in a casing 1 having a rectangular cross section and having an inlet 2 on one end and an outlet 3 on the other end. In this ceiling air conditioner, an inlet/outlet 22 is opened on one side 1c of the left and right sides of the casing 1 facing the blower 7, and a lid 23 for opening and closing the inlet/outlet 22 is provided. The motor 8 is connected between the opening 22 and the blower 7.
On the other hand, sliding guide frames 14, which vertically oppose each other and extend in the left-right direction, are disposed on the lower surface 1a and upper surface 1b of the casing 1 facing the loading/unloading port 22, respectively.

When the blower 7 and the motor 8 are pulled out while sliding, the blower 7 and the motor 8 are pulled out as a unit, making it easy to take them out.
Moreover, the screws etc. that are operated to take out the
All of them are on the entrance/exit 22 side, so the entrance/exit 22
It is only necessary to secure service space on one side, and the air conditioner can be installed even in narrow spaces where service space can only be secured on one side, reducing the constraints imposed by securing service space on both sides by half. The degree of freedom in installation can be increased.

In addition, in a large-capacity ceiling air conditioner, if the mounting plate 10, blower 7, and motor 8 are arranged side by side with the units left and right, the service space for loading and unloading the air conditioners is only needed on one side. The length will be halved.

(Example) Hereinafter, an example of this invention will be described in detail based on the drawings.

1 and 2, a ceiling-embedded air conditioner C has an inlet 2 and an outlet 3 that open at both front and rear end surfaces of a square box-shaped casing 1 with a square cross section, and a suction duct 4 is connected to these. are connected to a blow-off duct 5, and communicated with the interior of the room via both ducts 4 and 5. A heat exchanger 6 is disposed inside the casing 1 near the suction port 2, and a blower 7 and a motor 8 for driving the blower 7 are disposed near the outlet 3. The blower 7 and the motor 8 are arranged in the left-right direction of the casing, and the blower 7 is connected to the output shaft 8a of the motor 8.
are directly connected by fixing the rotor 9.

A mounting plate 10 is provided for fixing the blower 7. The mounting plate 10 is a plate-shaped body that completely partitions between the blower 7 and the outlet 3 in the casing 1, and the outlet 7 of the blower 7 is provided on one side of the plate surface.
The blower 7 is fixed with a screw 11 in a state where the abuts a. A port 12 is opened in the plate surface facing the discharge port 7a. This mounting plate 10 is inserted into and removed from the casing 1. For this purpose, sliding guide frames 14 and 15 extending in the left-right direction of the casing are fixed to the lower surface 1a and upper surface 1b of the casing 1, respectively, so as to face each other vertically. In addition, corresponding to both sliding guide frames 14 and 15,
Slide walls 16 and 17 are formed at the lower and upper ends of the mounting plate 10, respectively. The lower sliding wall 16 is formed with an L-shaped cross section, and is supported so that it can slide in the left-right direction on the sliding guide frame 14, which has a U-shaped cross section, while being positioned in the vertical direction and the front-back direction. There is. The upper sliding wall 17 is

Further, the left and right portions of both spaces are completely partitioned by rubber sealing members 18, 18 that are pressed against the left and right edges of the mounting plate 10.

On the casing lower surface 1a facing the blower 7,
A pair of front and rear mounting bases 19, 19 extending in the left-right direction in parallel with the sliding guide frame 14 is fixed.
Then, use both mounting stands 19, 19 to install the blower 7.
and both mounting bases 19, so that the motor 8 can be pulled out.
Slide pieces 21, 21 are provided on 19 and are supported so as to be slidable in the left and right direction. The bottom surface of the blower 7 is placed and fixed on the slide pieces 21, 21, and the slide pieces 21, 21
A gate-shaped motor stand 20 is placed on top and fixed with screws, and the motor 8 is fixed to this with screws.
One mounting base 19 also serves as a mounting base for the heat exchanger 6.

A mounting plate 1 is attached to one side 1c of the casing 1.
An inlet/outlet opening 22 is opened corresponding to the installation area of the air blower 0 and the blower 7. This inlet/outlet 22 is covered with a lid 23 detachably fixed to the side surface 1c. One side of the sealing material 18 is fixed to the inner surface of the lid 23. Inlet/outlet 22
The ends of both of the sliding walls 16, 17 nearer to each other are fixed to the respective sliding guide frames 14, 15 with fixing screws 24, respectively. This allows the blower 7 to be attached to the mounting plate 10.

With the above configuration, the blower 7 and motor 8
When taking it out of the casing 1, remove the screw 24 that fixes the mounting member 10 from the loading/unloading port 22 side, and remove the sliding guide frames 14, 15 and the mounting bases 19, 19.
If the mounting plate 10 and the slide piece 21 are pulled out while sliding along the sides, the blower 7 and the motor 8 are pulled out as a unit, and both can be easily taken out. Furthermore, since the screws that are operated for removal are all on the loading/unloading port 22 side, it is only necessary to secure the service space S on the loading/unloading port 22 side, and even in a narrow place where the service space S can only be secured on one side, air A harmonizer C can be installed.

(Another Embodiment) FIG. 3 shows a case where this invention is applied to a large-capacity air conditioner C. In this case, the mounting plate 10, the blower 7, and the motor 8 in the above embodiment are integrated into one unit, and by arranging these units side by side on the left and right, the amount of air blown can be increased. It's on. Each mounting plate 1

A seal wall portion 25 is formed to improve sealing performance at the 10 connecting points. Note that the same reference numerals are given to the same members as in the above embodiment.

Incidentally, when the blowers 7 are used in pairs as described above, conventionally the blowers 7, 7 are simultaneously slid by a single motor placed between the two blowers 7, 7, but as described above. If motors 8 and 8 are provided for each blower 7 and 7 so that they can be slid individually, the service space S can be reduced to one side and its length can be reduced to half, as shown in the previous embodiment. If the capacity of the blower 7 and the blower 7 explained in FIG. 3 match, the blower 7, motor 8, and mounting plate 1
It is possible to share each member such as 0, which is advantageous in reducing manufacturing costs.

In addition to the above, this invention can be implemented with some modifications as follows. For example, in the above embodiment, the mounting plate 10 also served as a partition wall, but
A separate partition wall is provided, and the mounting plate 10 is simply used as the blower 7.
The only function is to fixedly support the

Moreover, this invention also includes an air conditioner C in which the discharge port 7a of the blower 7 is opened facing the upstream side of the heat exchanger 6.
It is assumed that the present invention will be applied to a ceiling-suspended type, and is not limited to the above-mentioned embodiment.

(Effects of the invention) As explained above, according to this invention, the blower 7 is fixed to the mounting plate 10 that is slidable with respect to the sliding guide frames 14 and 15, and the blower 7 and the motor that drives it are fixed. 8 and a pair of mounting bases 19,1
The blower 7 is mounted and fixed on a slide piece 21 that can be slid relative to the blower 7 to form a single unit, and can be inserted and removed from the opening 22 provided on one side of the casing 1.
The motor 8 can be set in a fixed position or taken out of the casing 1 by inserting and removing the mounting plate 10. In addition, since the motor 8 is arranged between the blower 7 and the entrance/exit 22 and the fixing structure of the mounting plate 10 is concentrated on the space between the blower 7 and the entrance/exit 22, the blower can be operated only on the entrance/exit 22 side. 7
or take out the motor 8.
This makes it possible to easily perform maintenance work, which would otherwise be difficult due to work on the ceiling, and improve work efficiency. In addition, since the service space only needs to be provided on the side where the inlet/outlet 22 is provided, the air conditioner can be installed even in narrow spaces where the service space can only be secured on one side, making it easier to decide on the installation location. This increases the degree of freedom.

In addition, if the above-mentioned units are arranged side by side in a large capacity air conditioner, there is an advantage that the service space is required on one side and its length can be halved.
