Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a drain pan used in an air conditioner for ships and the like.

<Prior Art> Normally, in the indoor unit of a separate type air conditioner, the drain generated on the heat exchanger or the outer surface of the rear panel is received horizontally by a drain pan whose bottom surface is inclined in one direction. The drain pan is configured to discharge to the outside through a drain port provided at the side end on the one direction side (for example, Japanese Utility Model Publication No. 56-81325).

<Problems to be Solved by the Invention> However, when the above normal indoor unit is used for indoor air conditioning in a ship, there are the following problems. That is, in the drain pan of the normal indoor unit, the discharge port is provided only on the side end on the one direction side where the bottom surface is inclined as described above. Therefore, when the ship swings to the drain pan drain side, the drain water in the drain pan flows to the drain port side at a time, so the drain water cannot be drained in time and the drain water is drained from the drain pan side wall. It will overflow. On the other hand, when it swings to the side of the anti-drainage port, there is no drainage port on the side of the anti-drainage port and the height of the side surface is low. There's a problem. Therefore, in order to solve the problem, the capacity of the drain pan may be increased or the depth of the drain pan may be increased. However, if so, the size of the drain pan becomes large and the indoor unit itself becomes large. Therefore, there is a problem that the cost becomes high and at the same time, it is unsuitable for a ship that needs to effectively use a narrow space.

Therefore, an object of the present invention is to increase the size and increase the cost of a drain pan that does not allow drain water to overflow from both side ends even when the ship is rocked in the longitudinal direction of the drain pan when installed on a ship or the like. To provide without.

<Means for Solving the Problems> In order to achieve the above object, the drain pan of the present invention has a bottom surface 1a inclined toward one of the longitudinal directions as illustrated in FIG. 1 and FIG. A drain pan having a discharge port 3 for discharging drain water to the outside at the one side end, and a drain port 5 provided at the other side end in the longitudinal direction of the drain pan, and the drain pan being disposed in the drain pan. The drain pan is divided into a plurality of chambers, and a partition plate 11 having a communication portion 14 that communicates a part of the divided chambers is provided.

<Operation> When the drain pan is inclined to either side in the longitudinal direction, the drain water in the drain pan tends to flow toward one or the other side end portion in the longitudinal direction. However, the inside of the drain pan is partitioned by a partition plate 11 having a communication part 14 into a plurality of rooms, some of which are in communication. Therefore, the drain water in each partitioned room gradually flows into the adjacent room via the communication portion 14, and further flows toward any one of the side end portions depending on the inclination direction of the drain pan. At that time, since the discharge ports are provided at both side ends of the drain pan, the drain water reaching either of the both side ends of the drain pan is discharged to the outside from the drain port provided at the gap between the both side ends. To be done.

That is, the partition plate 11 functions as a damper and prevents the drain water from flowing into the side end portion of the drain pan all at once. Further, the drain ports provided at both end portions of the drain pan drain the drain water regardless of which side the drain pan is inclined in the longitudinal direction.

<Embodiment> Hereinafter, the present invention will be described in detail with reference to an illustrated embodiment.

FIG. 1 is a plan view of an embodiment of the drain pan according to the present invention, FIG. 2 is a front view, and FIG. 3 is a side view. For example, the bottom surface 1a of the drain pan 1 is formed to be inclined rightward in the figure, and drain water collected from the drain pan 1 by dropping from a heat exchanger (not shown) or the like is fed along the inclined bottom surface 1a. It is designed to flow in the right direction in the figure. A water collecting section 2 is provided at the right-hand side end of the drain pan 1 so that the drain water flowing in the drain pan 1 is collected in the water collecting section 2. Furthermore, the drainage port 3 is provided in the water collecting unit 2 to
The drain water collected in the above is discharged from the drainage port 3 to the outside.

On the other hand, as shown in FIG. 4, the drain pan 1 has an inverted triangle at a position deeper than the bottom surface 1a of the drain pan 1 at the left-hand side end portion thereof, and the water collecting portion 4 communicating with the bottom surface 1a of the drain pan 1 is provided.
Is provided, and the drain water that has flowed to the left in the drain pan 1 due to the tilt of the drain pan 1 to the left in the drawing due to the swing of the indoor unit is collected in the water collecting section 4. Further, the water collecting section 4 is provided with a drain port 5 so that the drain water collected in the water collecting section 4 is discharged from the drain port 5 to the outside.

In the drain pan 1, as shown in FIG. 1, three partition members 8,8,8 are arranged. FIG. 5 is a front view (FIG. 5 (b)), a plan view (FIG. 5 (a)) and a side view (FIG. 5 (c)) of the partition member 8. The partition member 8 is configured by mounting three partition plates 11, 11, 11 vertically to the substrate 9 and the bottom plate 10 and in parallel at equal intervals. FIG. 6 is a sectional view of the partition member 8 taken along the line AA in FIG. 5 (b).
As shown in FIG. 6, a cutout portion 12 for determining a mounting position when the partition member 8 is installed in the drain pan 1 is provided below the substrate 9 of the partition member 8 as described later.

FIG. 7 is a sectional view taken along the line BB in FIG. 7th
As shown in the drawing, the shape of the partition plate 11 of the partition member 8 is substantially similar to the cross-sectional shape of the space formed by the side wall of the drain pan 1. The shape of the partition plate 11 is formed slightly smaller than the cross-sectional shape of the space of the drain pan 1. By doing so, the notch 12 of the partition member 11 is fitted to the rod-shaped mounting member 13 provided on the front side on the bottom surface 1a in the drain pan 1, and the substrate 9 is arranged substantially parallel to the front side wall of the drain pan 1. When the partition member 8 is installed in the drain pan 1 with a gap, a gap 14 is created between the partition plate 11 and the inner wall of the drain pan 1. That is, the gap 14 forms a communication portion that communicates a part of the room partitioned by the partition plate 11.

In front of the drain pan 1, a front water receiving portion 16 for receiving drain water overflowing forward from the drain pan 1 when the drain pan 1 is inclined forward due to the swing of the indoor unit is provided integrally with the drain pan 1. On the other hand, behind the drain pan 1, when the drain pan 1 tilts backward, the drain pan 1
A rear water receiving portion 17 for receiving the drain water overflowing from the rear is provided integrally with the drain pan. Both of the front water receiving portion 16 and the rear water receiving portion 17 communicate with the drain pan 1 at both end portions thereof. Therefore, the drain water overflowed to the front water receiving section 16 and the rear water receiving section 17 due to the inclination of the drain pan 1 in the front-rear direction is
By the inclination in the longitudinal direction, the water flows into the drain pan 1 from the side end portion of either the front water receiving portion 16 or the rear water receiving portion 17,
Further, the water is collected in either the water collecting portion 2 or the water collecting portion 4 and discharged to the outside through either the drainage port 3 or the drainage port 5.

When the drain pan 1 having the above-mentioned configuration is installed in a room such as a ship that swings back and forth and right and left, the drain water can be discharged to the outside without overflowing as follows. First, when the drain pan 1 swings in the longitudinal direction, the drain water in the drain pan 1 tends to flow toward one of the side ends with the inclination of the bottom surface 1a. At that time, as shown in FIG. 1, the inside of the drain pan 1 is a partition plate of the partition members 8,8,8 mounted in the drain pan 1, ...
It is divided into 10 rooms by. A small gap 14 (see FIG. 7) is provided between each partition plate 11 and the side wall of the drain pan 1. Therefore, the drain water in each of the partitioned chambers, which tends to flow toward one of the side ends of the drain pan 1, can flow only through the gap 14 between the partition plate 11 and the side wall of the drain pan 1, and at a time. It does not flow. Therefore, the amount of drain water flowing into the water collecting part 2 or the water collecting part 4 and the amount of drain water flowing out from the drain port 3 or the drain port 4 are balanced,
The drain water does not overflow from the water collecting section 2 or the water collecting section 4.

Further, since drain ports are provided at any side ends of the drain pan 1, it is possible to reliably drain the drain water in the drain pan 1 no matter which side the longitudinal direction of the drain pan 1 inclines. is there.

Next, when the drain pan 1 swings in the front-rear direction, the drain water in the drain pan 1 has an upper edge 1b, 1c of the drain pan 1.
Depending on the direction of inclination, the overflow occurs either in the front or in the rear of the drain pan 1. At that time, as shown in FIG. 7, the front water receiving portion 16 is provided in the front of the drain pan 1, while the rear water receiving portion 17 is provided in the rear thereof, so that the drain water overflowing from the drain pan 1 is received in front. It can be received by the water section 16 or the rear water receiving section 17. Then, as the drain pan 1 swings in the longitudinal direction, the front water receiving portion 16 or the rear water receiving portion 16
The drain water in 17 is collected in the water collecting section 2 or the water collecting section 4 via the drain pan 1 and discharged from the drain port 3 or the drain port 5.

As described above, in this embodiment, the partition member 8 provided with the partition plate 11 is installed in the drain pan 1 to partition the interior of the drain pan 1 into a plurality of chambers, and between the side wall of the drain pan 1 and the partition plate 11. A space 14 is provided between the adjacent rooms to communicate with each other. Further, a water collecting part 2 or a water collecting part 4 is provided at both end portions of the drain pan 1, and a drain port 3 or a drain port 5 is provided in the water collecting part 2 or the water collecting part 4. Therefore, even if the drain pan 1 is inclined in the longitudinal direction,
The drain water in the drain pan 1 is the partition plate 11 and the drain pan 1
Water collecting part 2 or water collecting part 4 gradually from the gap 14 with the side wall of
Flow into. Therefore, the drain water flows into the water collecting part 2 or the water collecting part 4 at a time and the water collecting part 2 or the water collecting part 4
Drain water does not overflow from the. Also,
Since the drainage ports are provided on both sides of the drain pan 1, the drainage port 3 can be positioned regardless of which side the drain pan 1 is inclined in the longitudinal direction.
Alternatively, drain water can be discharged to the outside from the drain port 5.

At this time, the drain pan 1 does not need to have a particularly large capacity or a high side wall, and can be made compact and at a low cost. Therefore, the indoor unit using the drain pan 1 according to the present embodiment can be sufficiently used as an indoor unit of an air conditioner for ships.

In the above-described embodiment, the communication portion provided on the partition plate 11 is formed by the gap 14 between the side wall of the drain pan 1 and the partition plate 11. However, the present invention is not limited to this, and a large number of small holes may be provided in the partition plate 11, for example.

In the above embodiment, the drain pan 1 is provided with the partition member 8 constituted by attaching the three partition plates 11 to the substrate 9 and the bottom plate 10.
The partition plate 11 is installed in the drain pan 1 by installing it inside. However, the method of mounting the partition plate in the drain pan 1 in this invention is not limited to this.

In the above embodiment, the front water receiving portion 16 or the rear water receiving portion 17 provided before and after the drain pan 1 is not provided with a partition plate. However, the present invention is not limited to this, and the front water receiving portion 16 or the rear water receiving portion 17 may be provided with a partition plate.

<Effects of the Invention> As is clear from the above, the drain pan of the present invention partitions the inside of the drain pan into a plurality of chambers by the partition plate having the communicating portion, and the drain ports are provided at both end portions in the longitudinal direction. Is inclined in the longitudinal direction, the drain water in each of the partitioned rooms gradually flows from the communication section to one of the side ends through the adjacent room.
Therefore, even if the drain pan is inclined to any side in the longitudinal direction, the drain water does not flow toward one of the side ends at once due to the damper action of the partition plate 11, and the drain water is supplied from any of the side ends. Can be discharged from either drain without overflowing.

Further, the drain pan of the present invention does not need to be made particularly large in size because the drain ports are provided at both end portions of the ordinary drain pan and partition plates are attached, and the above-described effect can be obtained at low cost.
