Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is installed on a ceiling or the like in a room, and sends cold and warm air in a predetermined direction in the room, and at the same time, performs all maintenance work such as inspection work, cleaning and replacement of parts in case of failure. The present invention relates to a cassette type fan coil unit that can be reliably and easily performed.

[0002]

2. Description of the Related Art Usually, a ceiling fan type cassette type fan coil unit of this kind has a mechanism such as a heat exchange coil, a drain pan, a filter and a blower arranged in a ventilation passage formed inside the machine body, A lower panel that can open a suction port and a blow-out port respectively is integrally attached to the lower part, and the return air from the room is sucked into the machine from the suction port by the drive of the blower, and heat is exchanged to a constant temperature.
It has a function of sending cold and warm air that can exchange heat from one of the outlets of the lower surface panel into the room.

[0003]

However, in the cassette type fan coil unit having these conventional structures, since the blower of a considerable weight is integrally mounted in advance in the machine as described above, maintenance such as inspection and cleaning in the machine is performed. When working, of course, the entire machine body must be removed from the ceiling together with the heat exchange coil and the blower,
This has the serious drawback of being associated with considerable effort and especially of danger. In view of the above problems, the present invention separates the main body of the machine from the blower section, removes only the blower section from the inside of the machine without removing the entire machine, and greatly reduces the risk and maintenance work and Its main purpose is to perform various tasks such as assembly easily and easily.

[0004]

As a means for achieving the above object, the present invention generally has a blower passage 2 formed in the machine, and a heat exchange coil 3 and a drain pan 4 are provided in the blower passage 2.
Are arranged so as to be closer to one side and the lower bottom surface is provided with an opening B, and the lower surface panel 6, the suction port 7,
A branch chamber A formed by integrally arranging the air outlet 8, the filter mechanism 9 and the blower 10 is vertically movable and detachably fitted, and the branch chamber A is further formed. Internal machine frame 11
The present invention aims to provide a cassette type fan coil unit in which the entire machine body is made lighter by forming the above with a lightweight material such as styrofoam.

[0005]

The fan coil unit having the above structure is previously installed on the ceiling or the like in the room. Blower 1 in this state
When driving 0, the air on the indoor side returns to the inside of the machine through the suction port 7 below the machine body 1, flows into the air passage 2 through the filter mechanism 9, and heat is exchanged to an appropriate temperature by the heat exchange coil 3. The heat-exchanged cool and warm air is sent to the room through the branch chamber A from the blow-out port 8 below the chamber.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 is a box-shaped machine body having an opening B on the entire lower bottom surface, 2
A heat exchange coil 3 and a drain pan 4 are installed on one side of the air passage formed in the machine body 1 on the inside of the passage. Further, by disposing the heat exchange coil 3 and the drain pan 4 close to one side in the air passage 2, a space space c of the blower 10 is naturally formed in the air passage on the front surface of the heat exchange coil 3. Become. Further, a humidifier may be installed in the air passage 2 if necessary. Branch chamber A
Is formed by surrounding the lower circumference with the outer machine frame 5,
Inside the chamber 6, a suction air passage a is formed inside, and each blow air passage b is formed adjacent to the outside, and a suction port 7 is formed on both sides of the lower panel 6 so as to communicate with the suction air passage a. The air outlets 8 are opened inward and outward in parallel with each other so as to communicate with the blowing air passage b. According to the present invention, a filter mechanism 9 and a blower 10 are integrally attached to an internal machine frame 11 which forms the branch chamber A, and the entire branch chamber A is formed in a lower bottom opening B of the machine body 1.
It is vertically movable and detachably fitted to the section, and is fixed at a predetermined position. The fixing means is not limited to the fixing method by screwing, but the outer diameter of the branch chamber A is made larger than the diameter of the opening B of the machine body 1 and fixed by utilizing the pressure surface action by the surface contact. Means or any other fastening method can be used, and it is also considered that the entire branch chamber A is attached to the opening B so as to be openable and closable.

Further, in the present invention, the entire inner chamber frame 11 constituting the branch chamber A is made of a lightweight material such as styrofoam, so that the entire branch chamber A can be made very light. .

Although only the required number of the suction ports 7 and the blow-out ports 8 are opened on the surface of the lower panel 6 depending on the installation location or the like, the air flow is changed to the intermediate portion between the suction ports 7 and the blow-out ports 8. It is also a consideration that the blade 12 is movably supported and the airflow from the air outlet 8 can be changed in any direction depending on the inclination angle.

[0009]

As described above, the cassette type fan coil unit according to the present invention is provided with the suction port 7 and the blow port 8 at the lower opening B of the machine body 1, and in particular, the blower 10 is integrally formed. Since the branch chamber A is movable up and down and is detachably fitted, there is no danger of removing the entire machine body that is heavier than the ceiling surface during maintenance work, and only the branch chamber A is used. By removing, the opening B portion of the machine body 1 is enlarged, so that various works such as maintenance in the machine can be carried out very smoothly and easily.

According to the second aspect of the present invention, the heat exchange coil 3 is installed at one side of the air passage 2 so that the heat exchange coil 3 can be checked at the deepest part of the machine.
It is easy to clean and at the time of operation, the indoor area in front of the coil, that is, the area of the space space c of the blower becomes large. Therefore, the noise in the machine is naturally reduced along with the decrease in the wind speed in the room. There is also the effect of.

Further, as described in claim 3, since the branch chamber A is formed of a lightweight material such as styrofoam, it is extremely easy to attach and detach from the main body of the branch chamber A, and molding and Transportation,
It also has various advantages such as various operations such as assembly, which are very easy and suitable for mass production, and can be supplied at a low price.
