Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling-embedded air conditioner installed by being embedded in a ceiling.

[0002]

2. Description of the Related Art An example of a conventional air conditioner of this type is shown in FIGS. A heat exchanger 7, a drain pan 10, a motor 5, a blower 6, a bell mouth 12 and the like are built in the case main body 2 installed by being embedded in the ceiling 1, and the lower part of the case main body 2 is exposed to the ceiling surface. The ceiling panel 8 is attached.

A drain pan 10 for receiving the drain dropped from the heat exchanger 7 is disposed below the heat exchanger 7, and a bell mouth 12 is disposed below the drain pan 10.
A suction port 3 is formed in the central portion of the ceiling panel 8, and a blowout port 4 is formed adjacent to the suction port 3 and outside thereof. A suction grill 11 and a filter 13 are provided above the suction grill 11 at the suction port 3.

During operation of this air conditioner, refrigerant from an outdoor unit (not shown) circulates in the heat exchanger 7, and the motor 5 drives the blower 6. Then, the room air in the room 9 is guided from the suction port 3 through the suction grill 11 and the filter 13 to the bell mouth 12 and is sucked into the blower 6 to be urged. Then, by being cooled or overheated in the process of flowing through the heat exchanger 7, it becomes conditioned air and is blown out into the chamber 9 from the air outlet 4.

When the indoor air is cooled by the heat exchanger 7 during the cooling operation of this air conditioner, the water in the indoor air is condensed on the surface of the heat exchanger 7 to form a drain, which serves as a drain pan 10.
Drop into. This drain is collected in the drain reservoir 10A,
Drain pump 14 sucks up from here, and pipe 15
And it is discharged to the outside through the drain pipe 16.

[0006]

When the cooling operation time of the above conventional air conditioner is increased, the earth and sand and dust contained in the indoor air are accumulated in the drain reservoir 10A in the form of a muddle.
When the drain pump 14 sucks the medley, it is connected to the inside of the drain pump 14 or the pipe 15 so that the drain cannot be discharged.

[0007] Therefore, when the medley accumulates in the drain reservoir 10A, the ceiling panel 8, the bell mouth 12, the drain pan 10 and the like are removed from the case body 2 and the medoro accumulated in the drain reservoir 10A is vacuum pumped. However, there is a problem that it takes a lot of labor and time to remove and attach the bell mouth 12 and the drain pan 10.

SUMMARY OF THE INVENTION The present invention has been invented in order to solve the above-mentioned problems, and its gist is to expose the ceiling surface to the lower part of the case body installed by being embedded in the ceiling. Install the ceiling panel and install the heat exchanger and blower inside the case body.
A drain pan for receiving the drain dripping from the heat exchanger is provided in the lower part of the heat exchanger, a bell mouth for the blower is provided in the lower part of the drain pan, and the drain collected in the drain reservoir of the drain pan is drained. In a ceiling-embedded air conditioner that discharges to the outside via a pump, a cleaning hole is provided at a position of the drain pan and bellmouth just below the drain pump, and the cleaning hole is closed by a removable plug. It is in a ceiling-embedded air conditioner characterized by the above.

Another feature resides in that the cleaning hole has a size into which a suction pipe of a vacuum pump can be inserted.

[0010]

According to the present invention, when a large amount of smelt is accumulated in the drain reservoir, the plug is removed from the cleaning hole, and the suction hole of the vacuum pump is inserted from this cleaning hole to clean and remove the smelt. .

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENT One embodiment of the present invention is shown in FIG. Cleaning holes 21 and 22 having a size into which a suction tube of a vacuum pump (not shown) can be inserted are formed at positions corresponding to the drain pump 10 and the bell mouth 12 just below the drain pump 14, and these cleaning holes 21 and 22 are formed. Is always closed by inserting a removable plug 23 into it. In FIG. 1, 2
Is a case body, 7 is a heat exchanger, 10A is a drain reservoir, 15 is a pipe, and 16 is a drain pipe.

Thus, during the cooling operation of the air conditioner, the water in the room air is condensed on the surface of the heat exchanger 7 and forms a drain, which drops in the drain pan 10. At this time, dust and earth and sand in the indoor air are adsorbed by the drain attached to the surface of the heat exchanger 7, and are accompanied by the drain and enter the drain pan 10. This drain is collected in the drain reservoir 10A, and dust and earth are collected in the drain reservoir.
The sediment is settled in 10A, only the drain is sucked up by the drain pump 14, and is discharged to the outside through the pipe 15 and the drain pipe 16.

As the cooling operation time increases, the drain reservoir 10A
At the same time, the amount of dust and sand accumulated in the area increases, and at the same time, it becomes a muddle. In this case, after lowering the ceiling panel 8, the stopper 23 is pulled out from the cleaning holes 21 and 22,
A suction pipe, a brush, a scraping rod, etc. of a vacuum pump are inserted into the drain reservoir 10A from 21 and 22 to clean and remove the medley accumulated on the bottom of the drain reservoir 10A.

[0014]

According to the present invention, when a large amount of medley is accumulated in the drain reservoir, the plug is removed from the washing hole, and the meditation is removed from the washing hole. As a result, it is not necessary to remove or attach the bell mouth and the drain pan as in the conventional case, so that the hem can be easily and quickly cleaned and removed.

Then, a large amount of medley is accumulated in the drain reservoir at a position directly below the drain pump, but since the cleaning hole is provided at a position directly below the drain pump, the medoro is efficiently removed. Can be cleaned and removed.

If the above-mentioned cleaning hole has a size into which the suction pipe of the vacuum pump can be inserted, the medley accumulated in the drain reservoir can be quickly cleaned and removed using the vacuum pump.
