Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a ceiling-embedded air conditioner installed in the ceiling of a general building.

[Conventional technology]

Fig. 3 is a side view showing a conventional air conditioner shown in, for example, Japanese Utility Model Publication No. 50-6198. In the figure, 1 is a heat exchanger, 2 is a blower, and 3 is a duct installed in an opening in the ceiling. 4 is a drain pan, 5 is a main body case installed on the upper surface of the ceiling, and the discharge port 3 is connected to an opening provided in the ceiling through a duct. It's set up just like you want it to be. Covers 6 and 7 made of iron plates are attached to the main body case 5 with screws 9.

Note that the cover 7 has a suction port 8. Note that A is the ceiling and B is the ceiling slab. Although not described in detail in the above-mentioned publication, FIG. 4 is a plan structural view showing a conventionally known mounting method for the fan case 2b, in which 10 is a motor, and 11 is a fan mounted on the shaft of the motor 10. , 12 is a motor mounting foot for attaching the motor 10 to the side of the fan case 2b, 13 is an L-shaped metal fitting fixed to both sides of the fan case 2b, and the fan case 2b is connected to the blower stand 2a with a set screw 15. It has been stopped.

Next, the operation will be explained. When a duct for taking in air is connected to the suction port 8, the air taken in from the duct passes through the suction port 8, is forcibly blown by the blower 2, passes through the heat exchanger 1, and then flows from the discharge port 3 through the duct. Cold or warm air is discharged into the room. Next, when it becomes necessary to remove the blower, remove one of the covers 6 and remove the setscrews 15 to remove the main parts of the blower 2, such as the fan case 2b, motor 10, and fan 11, into one unit. Take it outside.

[Problem that the invention attempts to solve]

Since the conventional device is configured as described above, for example, if the cover 6 is located on the upper and lower surfaces of the main body case 5 and there is sufficient ceiling height, the maintenance space between the device and the building is small. However, the ceiling height is generally narrow and the blower 2 is installed from the top and bottom.
The reality is that this service is not available. Also, inside the ceiling, there are many hanging bolts for hanging the ceiling.
There were problems such as the fact that it was impossible to pull out the blower 2 along with the blower stand 2a sideways.

This idea was made in order to solve the above-mentioned problems, and it is possible to obtain a device that allows removal and service of the blower 2 regardless of the position of the suction port 8 in any of three directions: top, bottom, and sideways. The purpose is to

[Means for solving problems]

The air conditioner according to this invention has an inspection hole through which the blower 2 can be seen on the side of the main body case 5, a motor is attached to one side of the fan case of the blower 2 via a mounting foot, and furthermore, an inspection hole is provided on both sides of the fan case. One side of the L-shaped mounting foot is hooked to the blower stand 2a, and the other side is screwed.

[Effect]

The blower 2 in this invention has a fan case hooked on the blower stand 2a.
To take out a motor and a fan, which are the main parts of a blower 2, out of the device without pulling out the blower.

[Example of idea]

An embodiment of this invention will be described below with reference to the drawings. In FIG. 1, 10 is a motor, 11 is a fan, and 12 is a motor 10 mounted on the side of the fan case 2b.
13 is an L-shaped fitting for attaching the fan case 2b to the blower stand 2a, 14 is a hooking fitting provided on the blower stand 2a,
Numeral 15 is a set screw that locks the fan case 2b to the blower stand 2a. 16 is a blower inspection port provided on both sides of the main body 5, and 17 is an inspection port cover. C and D are inspection holes provided in ceiling A.

To take out the motor 10 and fan 11, which are the main parts of the blower 2, for replacement or inspection and cleaning, remove the inspection port cover 17 from the inspection port C in the ceiling A, and open the inlet on the side where the motor 10 is not installed. After removing the ring 2c, the fan 11 is removed from the shaft of the motor 10. Next, the inspection port cover 17 is removed from the inspection port D, and the set screw 15 of the fan case 2b is removed to remove the fan case 2b, which is integral with the motor 10 and fan 11, and taken out of the machine.

In the above embodiment, the case of a double-shaft motor has been described, but in the case of a single-shaft motor type, the main parts of the blower can be removed from one inspection port by configuring it as shown in FIG.

Further, in the above embodiment, a case where an inspection opening is provided in the ceiling has been described, but even if there is no inspection opening, the same effect can be achieved as long as the inspection opening can be entered into the ceiling.

[Effect of idea]

As described above, according to this invention, the main parts of the blower are configured so that they can be taken out from the side of the main body, so even in installation conditions where there is no space above or below the main body in the ceiling and servicing from the top or bottom is impossible. This has the effect of making it easier to maintain the blower.
