Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an improvement of an auxiliary drain receiving device for receiving condensed water from piping or valves of an air conditioner.

[Conventional technology]

An air conditioner equipped with this type of conventional auxiliary drain receiving device will be explained with reference to FIGS. 4 and 5.

In FIGS. 4 and 5, reference numeral 1 denotes an air conditioner main body installed inside the ceiling A, in which a heat exchanger and a blower (not shown) are built-in. Reference numeral 2 denotes a panel equipped with an air outlet 3, an air inlet 4, and an opening/closing opening for inspection 5, which is exposed from the ceiling surface 9 toward the indoor B side and is attached to the air conditioner main body 1. Further, pipes 6a and 6b for supplying cold and hot water are connected to the heat exchanger of the air conditioner main body 1, and the pipes 6a and 6b are connected to the heat exchanger to adjust or adjust the cold and hot water. Switching valves 7a and 7b are interposed. Reference numeral 8 denotes a drain dish constituting an auxiliary drain receiving device located below the valves 7a and 7b, and this drain dish 8 is connected to the pipes 6a and 7b.
It receives condensed water that has condensed on the non-insulated covered portion of 6b, valves 7a, 7b, etc. Also, 10
is an inspection port provided in the ceiling surface 9.

In the conventional air conditioner as described above, if cold water is circulated through the pipes 6a and 6b during cooling operation, the warm air inside the ceiling A will cause the pipes 6a and 6 to flow.
Condensation occurs on the surfaces of the valves 7a and 7b, and as this condensation progresses, it becomes condensed water, which eventually flows down the surface and falls into the auxiliary drain pan 8.

[Problem that the invention attempts to solve]

In the conventional air conditioner configured as described above, the auxiliary drain tray 8 is positioned directly above the inspection opening 5 of the panel 2 and covers the inspection opening 5. Therefore, the drain pan 8 becomes an obstacle and the valves 7a, 7 from the downward direction, that is, from the indoor side B.
There are problems such as not being able to operate the pipes 6a and 6b or inspect the pipes 6a and 6b. Therefore, in the past, an inspection opening 10 was generally provided in the ceiling surface 9. However, providing the inspection port 10 not only spoils the appearance of the ceiling and is undesirable in terms of design, but also
Problems such as ceiling construction became complicated and construction costs increased.

This invention was made in order to solve the conventional problems as described above, and the aim is to provide an auxiliary drain receiving device for an air conditioner that makes it easy to operate the valve or inspect the piping from the inspection opening. purpose.

[Means to solve the problem]

The auxiliary drain receiving device for an air conditioner according to this invention is composed of two parts, a drain tray and a drain tray support member, and the drain tray is detachably attached to the drain tray support member.

[Action]

In this invention, when the drain tray is removed from the drain tray support member, the hot and cold water pipes and valves are exposed at the inspection opening, making it easy to operate the valves and inspect the piping from the inspection opening. It can be done.

〔Example〕

An embodiment of this invention will be described below with reference to the drawings.

FIGS. 1 to 3 show an example in which the auxiliary drain receiving device according to the present invention is applied to a ceiling type air conditioner. In the drawings, parts that are the same as those in FIGS. 4 and 5 are given the same reference numerals, and their explanation will be omitted, and the explanation will focus on parts that are different from the conventional ones.

That is, the part of this invention that differs from the conventional one is the piping 6.
a, 6b and the valves 7a, 7b, and the drain receiving mechanism 11 includes a drain tray 12 and a drain supporting it, as shown in FIGS. 1 and 2. Dish support member 1
3 and 14.

The drain dish 12 has left and right side walls 12a, 12b with height dimensions A, B, and A<B from the support base side to the tip side, and the height dimension C of the support base side side wall 12c is B. The central part of the locking side wall 12c is removed and a drain port 1 is installed at the edge of the bottom plate 12d in the removed part.
2e is formed.

Further, the drain tray support members 13 and 14 have channel-shaped engaging portions 13a and 14 that engage with the support base sides of the left and right side walls 12a and 12b of the drain tray 12.
a, and support portions 13b and 14b formed integrally with the engaging portions 13a and 14a, respectively, and the air conditioner main body 1 of each of the support portions 13b and 14b.
The mounting pieces 13c and 14c have mounting holes 15 and 16.
are drilled in each. Numeral 17 is a mounting screw for attaching the drain tray support members 13 and 14 to the air conditioner main body 1, and 18 is a heat insulating material for preventing dew condensation on the outside of the air conditioner main body 1.

In the auxiliary drain receiving device constructed as described above, the drain tray 12 is normally supported by support members 13 and 14 attached to the air conditioner main body 1 by screws 17, as shown in FIG. At this time, the side walls 12a, 12b of the drain tray 12 engage with the engaging portions 13a, 14a of the support members 13, 14, and since there is the locking side wall 12c, the drain tray 12 engages with the engaging portions 13a, 14a. It will not fall out and will remain stable. In addition, the piping 6a,
6b and the valves 7a, 7b into the drain pan 12 is discharged from the drain port 12e to the main body 1 side through the drain pipe 19 shown in FIG.

When inspecting the pipes 6a, 6b and operating the valves 7a, 7b, insert a tool through the inspection opening 5 of the panel 2 and loosen the mounting screws 17. It rotates in the direction of the arrow about the mounting screw 17 as a fulcrum, as shown by the two-dot chain line in FIG. As a result, each engaging portion 13a,
14a comes off from the side walls 12a, 12b of the drain tray 12, allowing the drain tray to be removed. In this state, the drain pan 12 covering the lower part of the pipes and valves is removed, so the pipes and valves are opened to the opening/closing opening 5 for inspection.
Piping inspections and valve operations can be easily performed from the beginning.

In the above embodiment, the locking side wall 12c of the drain plate 12 is set to B<C, and the drain plate supporting member 13,
The locking side wall 1 is attached to the end surface of the engaging portions 13a, 14a of 14.
Although the case has been described in which the inner surfaces of the locking side walls 12c are in contact with each other, the height dimension C of the locking side wall 12c is set as C=B,
Even if the channel-like engaging portions 13a, 14a of the drain tray support members 13, 14 are sloped in accordance with the side walls 12a, 12b, the same effects as in the above embodiment can be obtained.

[Effects of the Invention] As described above, according to this invention, the auxiliary drain receiving device is divided into two parts, the drain tray and the drain tray support member, and the drain tray can be detachably attached to the engaging portion of the drain tray support member. Since it is configured to be mounted, valve operation and piping inspection can be easily performed from the inspection opening/closing opening.

Furthermore, there is no need to provide an inspection port or the like on the ceiling surface, which improves the appearance and design of the ceiling and reduces ceiling construction costs.
