Description

[Detailed Description of the Invention] This invention relates to a fan coil unit equipped with a dew pan that is mounted through the main body.

An embodiment of this invention will be described below with reference to the drawings. Fig. 1 is a configuration diagram of a fan coil unit installed in the ceiling. In the figure, 1 is the main body, 2 is the blower fixed in the main body 1, and 3 is the fan coil unit installed in the horizontal direction of the blower 2. 4 is a dew pan installed below the heat exchanger 3, both ends of which are bored in both side walls of the main body 1 as shown in Fig. 2. It has an external lead-out portion 4a led out to the outside through the through-hole 5, and the dew pan 4 is supported by the lower edge 5a of the through-hole 5. Reference numeral 6 denotes a discharge port provided in the external outlet portion 4a for discharging the condensed water collected in the dew pan 4 to the outside, and is connected to a drain pipe (not shown). Reference numerals 7 and 8 are inlet and outlet connection ports for connecting inlet side piping and outlet side piping (not shown) for supplying cold water or hot water to the heat exchanger 3. Reference numeral 9 denotes an air vent valve that communicates with the outlet connection port 8 of the heat exchanger 3 and bleeds out the air inside the heat exchanger 3, and an air vent pipe 10 is connected to the discharge port. As shown in FIG. 2, 11 is an L-shaped plate consisting of a closing surface 11a that closes the opening surface of the external lead-out portion 4a of the dew pan 4 within the external lead-out portion 4a, and a mounting surface 11b that is attached to the outer surface of the side wall of the main body 1. The closing plate 12 is an air vent hole bored in the closing surface 11a of the closing plate 11, into which the end of the air vent tube 10 is inserted and supported. 13 is a mounting screw for attaching the closing plate 11 to the side wall of the main body 1 on one side of the mounting surface 11b of the closing plate 11; 14 is the mounting surface 1 of the closing plate 11;
This is a protrusion cut and raised toward the side wall of the main body 1 on the other side of 1b, and is provided corresponding to the upper edge of the through hole 5. Reference numerals 15 and 16 indicate an air inlet and an air outlet provided on the lower surface of the main body 1, and 17 indicates a heat insulating lead-out member affixed to the side wall of the main body 1.

Next, the effect will be explained. Cold water or hot water supplied from a heat source (not shown) is transferred to the heat exchanger 3.
is circulated into the heat exchanger 3 via the inlet and outlet connections 7, 8. On the other hand, the air to be conditioned is sucked in from the suction port 15 by the blower 2 and then transferred to the heat exchanger 3.
After exchanging heat with cold water or hot water, the water is blown into the room from the outlet 16. Especially when cooling,
Since dew condenses on the surface of the heat exchanger 3, the condensed water is collected in a dew pan 4 mounted below the heat exchanger 3 and is discharged to the outside through a discharge port 6. Also, during cooling, dew tends to form on the side wall of the main body 1 on the downstream side of the heat exchanger 3.
The condensed water that has condensed on the side wall is guided by the upper edge of the water guide member 17 and collected in the external outlet portion 4a of the dew pan 4. For this purpose, the dew pan 4 is led out to the outside, so that cold or warm air flows through the outlet 16.
In the process of being blown out, cold air or hot air from inside the main body 1 tends to leak to the outside through the external outlet portion 4a, but the closing plate 11 is bent into an L shape and the closing surface 1
Since the opening surface is covered by 1a, there is no leakage. Also, when installing the closing plate 11,
If the closing surface 11a of the closing plate 11 is accommodated in the dew pan 4 so as to close the opening surface thereof, and the upper surface of the protrusion 14 is brought into contact with the upper edge 5b of the through hole 5, the closing plate 1
1 is determined, and then the mounting screw 13 is tightened, the protrusion 14 is prevented from rotating the closing plate 11 due to the tightening of the mounting screw 13, and the dew catcher 4 is prevented from moving in its penetrating direction. Installed in the correct position.

On the other hand, the air vent valve 9 is pulled out from the heat exchanger 3 to the outside of the side wall of the main body 1 so that the valve can be operated from the outside, and is pulled out through the air vent pipe 10 to treat water discharged at the same time when air is vented. Since the dew is led out into the dew pan 4, the surrounding area is not contaminated. In addition, this air vent pipe 9 is made of a flexible tube such as a vinyl chloride pipe in order to allow the dew pan 4 to be attached and detached freely, and its tip is inserted into the air vent pipe hole 12 of the closing plate 11 and held firmly. It can be easily pulled out when needed.

As described above, according to this invention, the closing surface is accommodated within the opening surface of the external lead-out portion of the dew pan that is installed through the main body to collect condensed water on the side wall of the main body, and closes the opening surface. Since the closing plate is provided with a mounting surface that is attached to the side wall of the main body, cold or hot air can be blown out from the outlet without leaking from the opening surface of the dew pan. Since the air vent tube is provided with an air vent hole and the air vent tube is inserted into the hole and held, there is no need to manufacture a special holding fitting for the air vent tube.
