Description

[Detailed description of the invention] This invention is installed in the ceiling of a particularly quiet room such as a hotel or office, and provides ideal air conditioning and heating that is optimal for the indoor situation, and the overall shape is flat and compact. This invention relates to an efficient and energy-saving ceiling-mounted air conditioner.

Normally, most of the air conditioners installed in hotels, offices, etc. have a blower placed near the air inlet and outlet, so the internal electric motor and blower make noise. This made it difficult to find a quiet environment.

However, depending on the arrangement structure of each mechanism, it was not only difficult to install it in a narrow space on the ceiling of a room because it was bulky, but also unsightly in terms of design.

In view of these drawbacks, the present invention has made the overall shape of the fuselage extremely flat and small, allowing it to be installed in any narrow ceiling space, as well as directing the air to the desired direction, such as one-way or two-way air outlet, depending on the indoor environment. The purpose of this system is to provide air conditioning as conveniently as possible, and a partition plate is used inside the oblong aircraft to form a suction passage at the bottom and an oblong U-shaped ventilation passage at the top, which is similar to a ventilation passage. A blower is arranged in the air passageway at a considerable distance from the air outlet, and is connected to the air outlet provided on the front and lower surface of the airframe. It is an object of the present invention to provide a ceiling-embedded air conditioner characterized in that a lower panel having suction ports communicating with the suction passage on both sides is fitted so as to be openable and replaceable.

Hereinafter, detailed explanation will be given with reference to drawings illustrating a specific example structure of the present invention.
It is divided into upper and lower parts by , and a horizontally elongated U-shaped ventilation passage with a suction passage 3 in the lower part and a ventilation passage 4 in the upper part is formed.
An air blower 6 is installed on one side of the air blower 6, and a heat exchange coil 7 is installed on the opposite side of the air blower 6 at a considerable distance, and air outlets 8 are provided at the front and bottom of the fuselage 1.
8' respectively.

Further, in the air passage 4, a noise reduction mechanism 9 of an appropriate shape is disposed at an intermediate portion between the air blower 6 and the heat exchange coil 7.

Reference numeral 10 indicates a drain pan.

The suction passage 3 communicates with suction ports 11 and 11' provided on both sides of the lower panel 12 on the bottom of the fuselage 1, and
On the other hand, a wing piece 13 is movably and rotatably supported at the suction port 11 .

14 is a maintenance panel and the lower panel 12
Similarly, the lower panel 12 and the maintenance panel 14 are equipped with building materials and decorative boards that are sound-absorbing and have appropriate designs and colors, and can be replaced and changed as desired.

It is also possible to add lighting equipment such as a fluorescent light or a turn light to the panel.

It goes without saying that the air outlet 8 and the suction ports 11, 11' are each opened outward so that their positions can be adjusted freely.

The present invention has the above-mentioned structure, and in the case of a ceiling of a hotel, an office, etc., especially a room where the ceiling is designed downward at the entrance, the suction port 11 as shown in the first figure is used. is the lower surface of the entrance ceiling, and the air outlet 8 is buried in the ceiling with the air outlet 8 directed toward the room.

The air in the inlet area is sucked in through the suction ports 11 and 11', and while this air is appropriately cooled and air-conditioned, it is distributed into the room through the air outlet 8 and the lower air outlet 8', that is, in a two-way manner. It is.

In such a body, by rotatably moving the blade 13 in the direction of the dotted line 13' in the fourth figure, the air from the air passage 4 can be easily converted and used only to the front air outlet 8, that is, to have a one-way air blowing function. It is possible.

As described above, the ceiling-embedded air conditioner according to the present invention divides the inside of the fuselage 1 into upper and lower passages with the partition plate 2, and forms a horizontally long U-shaped ventilation passage. 4 becomes very long, and as a result, the distance between the air outlet 8 and the blower 6 becomes considerably large, and the concern that the sound generated by the air blower 6 flows out from the air outlet 8 is completely eliminated. There is also sufficient space for installing the noise reduction mechanism 9 in the ventilation passage 4, and by installing the noise reduction mechanism 9, it is possible to obtain a completely silent air conditioner/heater.

Moreover, as mentioned above, by operating the wing pieces 13, it is possible to easily switch between the one-way and two-way blowing systems, and furthermore, the lower both panels,
That is, by moving the lower panel 12 and the maintenance panel 14 downward, the lower surface of the fuselage 1 is opened wide, which makes it extremely easy to not only replace the filter 5 but also inspect internal mechanisms such as the blower 6. It has the following effects.

It also has the advantage that a sufficient design effect can be expected by replacing the building material of the bottom panel with one that has a design pattern that is most suitable for the seasons or for the room.
