Description

[Detailed description of the device]

[0001]

[Field of Industrial Application] This invention is installed on a ceiling in a room, etc., and at the same time as taking in indoor air, it is possible to arbitrarily and easily obtain cool and warm air of a required air volume in the room and inspect the inside of the machine after the ceiling is installed. The present invention relates to a cassette-type four-way blow-down ceiling-mounted air conditioner that can easily and surely perform the above-mentioned various tasks in an installed state.

[0002]

2. Description of the Related Art Conventionally, this type of cassette type four-way blowout ceiling air conditioner has a rectangular or annular heat exchange coil installed in the machine, and a blower is arranged in the center of the air-conditioner to cool and warm air. Was blown into the room. Further, most of them were blown from several air outlets directly through an air blowing passage that sucks indoor air from an air inlet formed at the center of the lower panel and forms it in the machine.

[0003]

[Problems to be Solved by the Invention] However, in the case where the annular heat exchange coil A is installed, work such as inspection and cleaning from the inside of the machine and the front side is performed because the heat exchange coil shape A is annular. It is impossible, and because it is installed on a ceiling in a high place, it is extremely difficult and there is a great deal of danger.

[0004]

SUMMARY OF THE INVENTION In view of the above problems, the present invention makes it possible to easily and reliably perform inspection work without fear of danger and to provide cool and warm air of a required air volume. A cassette-type four-way blow-off ceiling-mounted air conditioner that can immediately blow air in a predetermined direction, and in particular, can obtain a very good air-conditioning body in the peripheral direction of the room by making it blow in all directions on all sides. The main purpose of the blower is to provide the blower, and a blower 3 is provided in the blower passage 2 at the center of the inside of the airframe 1, and a plurality of heat exchange coils 4 and 4 are provided at a constant interval above the blower 3. Each of the air outlets 5 are installed so as to be opposed to each other, and the air passage 6 at the outer peripheral portion of the coil can be opened through the branch duct 9 on the lower surface panel 13 in all directions.
Is connected to. Further, the lower surface panel 13 is fitted together with the branch duct 9 so as to be movable up and down in the case a, and at the upper part of the case a within the space between the heat exchange coils 4, 4 on the front side, the back side, or the front and rear surfaces. The inspection port 10 is opened at a corresponding place to facilitate the inspection work inside the machine. Further, as described in claim 2, a plurality of blowers 3, 3 are arranged in the blower passage 2 at the center of the inside of the machine body 1, and the blowers 3, 3 are provided.
It is also possible to supply the required cold and warm air to the room by switching operation such as operation on both sides or one side of 3. Further, as described in claim 3, the suction port 1 of the suction passage 11 communicating with the blow passage 2 of the blower 2 below the machine body 1.
The lower surface panel 13 is attached to the opening 2 so as to be openable and closable, and the inspection work inside the machine is facilitated from the lower side of the machine body 1 together with the above-mentioned inspection from the front side.

[0005]

The function of this invention is that the air suction port 1 can be opened below the machine body.
The indoor air is sucked in from 2 and the heat exchange coils 4 and 4 installed in the machine perform heat exchange to a predetermined temperature, and the cold and warm air is blown by the operation of the blower 3 through the branch ducts 9 in the lower four directions. It is possible to send and receive good cool and warm air into the room from the outlet 5.

When the required air volume is to be obtained depending on the indoor conditions, one of the blowers 3 and 3 is stopped or operated so that one or two of the four outlets 5 or two or more of them are provided. It is possible to easily change the amount of air blown from the air blower opening to change the amount of air blown into the room.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 is an airframe inside which is a suction port 1 on the lower bottom surface of the airframe.
2, a suction passage 11 is formed so as to communicate with 2, and a lower surface panel 13 is provided in the air passage 6 at the inner peripheral portion of the machine via a branch duct 9.
The lower surface panel 13 is fitted in the machine a together with the branch duct 9 so as to be movable up and down, and is connected to the air outlets 5 that can be opened on all four sides of the machine. Multiple heat exchange coils 4 and 4 are installed facing each other,
In the suction passage 11, various mechanisms such as a medium performance filter 7, heat exchange coils 4 and 4, drain pans 8 and 8 are installed. Further, an inspection port 10 of an appropriate size is provided on the front part or the rear part or the front part or the rear part of the heat exchange coils 4 of the machine housing a for forming the air conditioner, at the corresponding positions, and the machine body 1 is externally provided. It is easy to inspect the inside. In addition, the blower 3
When a plurality of small blowers 3 are arranged in a back-to-back manner and each of the blowers 3 can be operated individually, the lower panel 13 is provided below the suction passage 11 of the machine body 1 and at the suction port 12.
It is also possible to install the whole so as to be openable and closable, and to inspect the inside of the machine easily from the opening like the above.

[0008]

As described above, according to the present invention, a plurality of heat exchange coils 4 and 4 are arranged at appropriate intervals in place of the conventional annular heat exchange coil, and the entire circumference is sucked into the branch duct 9 in the machine. Since it is arranged and formed in a four-way blow-out type, naturally a considerable gap portion is naturally formed between the plurality of heat exchange coils 4 and 4, and the inspection port 10 which can be opened in such a gap portion is formed. Therefore, it is possible to easily perform various operations such as inspecting and cleaning the inside of the machine easily and surely with the air conditioner installed on the ceiling. Further, by opening the lower surface panel 13 of the suction port 12, the inside of the machine can be inspected from the lower side of the machine, the filter can be attached and detached, along with the above-mentioned work.
It also has the advantage that maintenance work such as trouble repair can be easily performed.

In addition, several blowers 3 and 3 may be installed in the body according to the second aspect of the present invention to operate the blowers 3 and 3 at the same time, and each of them may be rotated or one of them may be stopped. Thus, the required air volume from the outlet 5 can be easily obtained, and therefore, there is a remarkable effect such that an ideal air-conditioning development can be delivered and delivered indoors.
