DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art An example of a conventional air conditioner of this type is shown in FIG. As shown in FIG. 2, a heat exchanger 7, a drain pan 10,
A motor 5, a blower 6, a baffle plate 12 and the like are built in, and a ceiling panel 8 facing a chamber 9 is attached to a lower portion of the case body 2. A suction port 3 is formed at the center of the ceiling panel 8, and an air outlet 4 is formed adjacent to the suction port 3.

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

[0004]

In the ceiling-mounted type air conditioner of this type, a part of the conditioned air blown out from the suction port 4 into the room 9 is entrained in the flow of room air sucked into the suction port 3. To avoid the so-called short circuit,
If air is to be sucked into the case body 2 from the space 20 above the ceiling, there is a problem that it takes a lot of trouble and time to attach / detach the filter 13 for filtering the sucked air or to clean it.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and its gist is to embed a case body containing a heat exchanger, a blower and the like in a ceiling. In the ceiling-mounted type air conditioner having a ceiling panel facing the room below the case body, a suction port is provided in a side wall of the case body, and the suction port is detachably attached substantially vertically to the suction port. Drilled through holes in the ceiling panel to raise and lower the filter
An embedded ceiling air conditioner is characterized in that a fitting member that fits into the through hole and closes the through hole is connected to a lower portion of the filter.

[0006]

According to the present invention, since the filter is provided with the above structure, the filter is raised from the room through the through hole formed in the ceiling panel, and the fitting member is fitted into the through hole and closed. It is attached almost vertically to the suction port provided on the side wall of the main body. If the user inserts the fitting member from the room and pulls it down, the filter is removed from the suction port, descends through the through hole, and is drawn into the room.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIG. A suction port 22 is provided on a side wall of the case body 2 and the suction port 22 is provided.
A filter 23 is detachably and substantially vertically attached to 22. The ceiling panel 8 has a through hole 24 for raising and lowering the filter 23. A fitting member 25 is connected to a lower portion of the filter 23. The fitting member 25 fits into the through hole 24 and when closed, the lower surface thereof is flush with the ceiling panel 8 and cooperates with the ceiling panel 8. Limit the airway. The blower 6 is located in a space 26 surrounded by the air guide plate 12 and the ceiling panel 8.
The ceiling panel 8 is provided with only the outlet 4. The ceiling 1 is provided with a suction port 21 at a position separated by the case body 2. The other configuration is the same as that of the conventional one shown in FIG. 2, and corresponding members are denoted by the same reference numerals.

However, during operation of the air conditioner,
When the blower 6 is driven by the filter 5, the room air in the room 9 enters the space 20 above the ceiling from the suction port 21, is sucked into the case body 2 through the suction port 22 and the filter 23, and
To form conditioned air that has been cooled or heated. The conditioned air is guided by the air guide plate 12, is sucked into the blower 6, is energized, and is blown out from the outlet 4 into the room 9.

If the filter 23 is clogged with dust in the air due to continuous operation for a long period of time, the filter 23 is pulled down by holding the fitting member 25 from the chamber 9 and pulling it downward. It is removed from 22 and descends through the through-hole 24 and is drawn into the chamber 9. When the filter 23 has been cleaned or replaced with a new filter 23, the filter 23 is raised from the chamber 9 through the through-hole 24, and the fitting member 25 is fitted into the through-hole 24 to close it. The upper end of the filter 23 abuts on the top plate 2a of the case main body 2, is mounted vertically on the suction port 22 so as to cover the same, and is held in this state by locking means (not shown).

The suction ports 22 can be provided on the four side walls of the case body 2, respectively.
May be installed so as to face the suction ports 22 and guide rails may be provided on the four corner frames of the case body 2 so that both side edges of each filter 23 are guided by these guide rails.

[0011]

According to the present invention, a suction port is provided in the side wall of the case body, and a through-hole for vertically moving a filter which is detachably attached to the suction port in a substantially vertical manner is formed in the ceiling panel. Since the fitting member that fits into this through hole and closes it is connected to the lower part of the filter, the filter is raised from the room through the through hole formed in the ceiling panel, and the fitting member is fitted into the through hole. When the filters are closed together, the filter is attached almost vertically to the suction port provided on the side wall of the case body. If the user inserts the fitting member from the room and pulls it down, the filter is removed from the suction port, descends through the through hole, and is drawn into the room. As a result, the attachment / detachment of the filter and the cleaning thereof are facilitated, so that the air in the space above the ceiling can be sucked into the case body.
