Description

[Detailed Description of the Invention] The present invention relates to a ceiling-embedded fan coil unit, and an object thereof is to facilitate maintenance and inspection of the ceiling-embedded fan coil unit.

As shown in FIG. 1, a conventional ceiling-embedded fan coil unit has a partition frame 4 that forms a right piping space 2 and a left piping space 3 inside a main body frame 1, and a blower 5 is installed inside the partition frame 4. and a heat exchanger (not shown), and drain pan 6.
A pair of frames 8, which are fixed with screws 7, are provided on the main body frame 1 so as to cross the right piping space 2 and the left piping space 3 from below the heat exchanger, and the through holes 9 provided in the frames 8 are provided.
The drain pan 6 was attached by screwing the screw 7 into the.

Therefore, as shown in FIG.
In order to receive the condensed water, the drain pan 6 is moved to the right side of the piping space 2, and the drain pan 6 is attached to the frame 8 using a large number of screws 7, and the piping is installed in the left piping space 3. When connecting, the drain pan 6 was moved to the left side of the piping space 3 and attached using screws 7, so when adjusting the valve 10 or performing maintenance inspections, it was necessary to loosen many screws 7 and remove the drain pan 6. However, it is very time-consuming and requires a lot of effort, and when it comes to a slightly larger ceiling-mounted fan coil unit, there is a drawback that it is impossible to attach and detach the drain pan by one person.

The present invention solves the above-mentioned conventional drawbacks, and will be described below with reference to FIGS. 2 to 5 showing one embodiment thereof.

In Figures 2 to 5, 11 is a ceiling-embedded fan coil unit main body (hereinafter referred to as the main body), 12 is a grill frame attached to the main body 11 so as to be exposed from the ceiling surface 13, and 14 is a grill. The mouth 15 and the air outlet 16 are separated by a partition plate 17, and the grill frame 12 is formed by a hinge 18.
It is set up so that it can be opened and closed freely.

19 is a screw that locks one end of the grill 14 to the grill frame 12; 20 is a blower provided in the main body 11; 21 is a heat exchanger provided in the air flow path of the blower 20;
1 is a partition plate that partitions the inside of the pipe into a right piping space 23 and a left piping space 24; 25 is a drain guide plate with one piece attached to the bottom of the heat exchanger 21; 26 is a drain drainage hole provided in the drain guide plate 25; , 27 are a pair of frames arranged below the heat exchanger 21, each having a substantially L-shaped cross section, and stretched between the partition plates 22.

28 is a drain pan provided with a hook part 29 and a holding piece 30 that slidably engages with the L-shaped part of the frame 27, is longer than the frame 27, and is located in either the right piping space 23 or the left piping space 24. It is provided so as to extend to the side.

31 is a holder provided on the main body 11 so that when the drain pan 28 is shifted to either the right piping space 23 side or the left piping space 24 side, the holding piece 30 on the biased side is stopped; The piping 33 is a valve that controls the flow rate of cold water or hot water flowing into the heat exchanger 21.

In the above configuration, for example, in the case of right-hand piping, as shown in FIG. The holding piece 30 provided on the main body 1
1, and the drain pan 28 is held by the frame 27 and the holder 31.

In this state, the condensed water in the heat exchanger 21 is received by the drain guide plate 25 and falls from the drain hole 26 onto the drain pan 28, and the condensed water condensed on the valve 33 is also received on the right piping space 23 side. The drain pan 28 extended therein can be received therein.

In addition, when piping is performed on the left piping space 24 side, by moving the drain pan 28 to the left piping space 24 side, condensed water from the heat exchanger 21 and valve 33 is received by the drain pan 28, as in the case of right piping. It is something that can be done.

Next, when performing maintenance inspection or valve adjustment on the ceiling-mounted fan coil unit connected by the right piping as shown in FIG. By opening the drain pan 28 and moving the drain pan 28, which is slidably held by the frame 27 via the hook portion 29, to the left piping space 24 side, the valve 33 is exposed, and the valve 33 is operated to adjust the flow rate. be able to.

After the adjustment of the valve 33 is completed, the drain pan 28 is moved to the right piping space 23 side and left in its original state.

Also, when it is necessary to remove the drain pan 28,
The drain pan 28 is removed from between the frames 27 so as to break the engagement between the hook portion 29 of the drain pan 28 and the frame 27.

As is clear from the above embodiments, according to the ceiling-embedded fan coil unit of the present invention, whether the piping is installed or the left piping is installed, it can be easily handled by simply sliding the drain pan, and internal maintenance and inspection can be carried out easily. The drain pan can be easily adjusted by moving the drain pan, and since there is no frame or the like to support the drain pan in the piping space during piping and adjustment, the work is easier.
