Description

[Detailed Description of the Invention] The present invention relates to an indoor unit for an air conditioner, particularly to the structure of a drain pipe storage section.

An indoor unit having a structure in which piping members such as a refrigerant pipe and a drain pipe can be stored in a recess formed by recessing the rear bottom of the indoor unit main body forward is known from Japanese Utility Model Application Publication No. 56-81324. However, in conventional indoor units of this type, it is common for all piping members to pass through the recess all at once, and therefore, the drain pipe extends vertically within the recess, thereby providing horizontal or downward distribution. The arrangement did not maintain the flow of water, which was undesirable as it obstructed the flow of drain.

The present invention has been devised in response to such conventional drawbacks, and an object of the present invention is to prevent drain from accumulating in the drain pipe and to simplify the work of storing the drain pipe.

To this end, the present invention provides an indoor unit in which piping members such as refrigerant pipes and drain pipes can be stored in a recessed part of the rear bottom of the indoor unit main body that is recessed forward. A protruding locking member is provided, and the drain pipe is housed in a space between the locking member and the inner wall surface so as to be positionable, and the drain pipe is positioned in a predetermined position while being locked to the locking member. By housing the drain pipe in the space, it becomes possible to easily fix the drain pipe while maintaining horizontal or downward distribution, and the intended purpose has been fully achieved.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows the main parts of a wall-mounted indoor unit in a separate air conditioner.
The casing consists of a front grille 2 forming a front surface having a top surface, a bottom surface, front halves of left and right sides, an inlet 4 and an outlet 5, and a unit frame 3 forming a rear half of the top surface, bottom surface and left and right sides, and a back surface. The indoor coil 8 and the cross-flow type fan 9 are divided into two parts and are housed inside the main unit with the front grille 2 removed from the unit frame 3.
It is now possible to provide services for required equipment such as

The unit frame 3 includes a frame main body 6 that forms the majority of the rear half of the back, top, and left and right sides along the wall surface of the mounting wall, and a frame bottom plate 7 that forms the remainder of the bottom and left and right sides. By recessing the rear bottom of the frame main body 6 forward, a recess 10 is provided at the rear of the bottom inside the indoor unit main body 1.

This recess 10 forms a space for accommodating the refrigerant pipes 11, 11 and the drain pipe 12. The bottom and both left and right sides are open, making it easy to insert and remove the refrigerant pipe 11 and drain pipe 12.

In the indoor unit having such a structure, an appropriate number of locking members 13 are provided on the inner wall surface of the recessed portion 10, and the locking members 13 projecting into the recessed portion 10 are surrounded by the locking members 13 and the inner wall surface. The space 14 is large enough to accommodate the drain pipe 12.
is formed.

The locking member 13 is provided in a protruding manner such that a gap slightly smaller than the outer diameter of the drain pipe 12 made of rubber or soft synthetic resin is maintained between the locking member 13 and the bottom portion of the inner wall surface of the recessed portion 10. They are provided at several locations dispersed in the width direction of the recessed portion 10.

In addition, when the frame main body part 6 is made of metal, the locking member 13 may be formed in a protruding manner by press working, while on the other hand, when the frame main body part 6 is a synthetic resin molded product, the locking member 13 is integrally molded. In particular, it is preferable that the locking member 13 has a thin structure and has elasticity.

In the indoor unit constructed as described above, piping members are stored in the recess 10 during the pipe connection work after installation on the wall.
2, when the drain pipe 12 is pushed into the space 14 from the position indicated by the dotted line, passing through the gap between the locking member 13 and the inner wall surface, as shown in FIG. Therefore, it is possible to stably install the drain pipe 12 horizontally or at a downward slope along the bottom plate portion of the inner wall surface of the recessed portion 10 (see FIG. 3), and the saddle member is used to It will be in the same state as if it were fixed appropriately.

In addition, when the locking member 13 is made of metal, the space 14 can be closed under light force by utilizing the deformation of the drain pipe 12.
If the drain pipe 12 and the locking member 13 are made of synthetic resin and have elasticity,
It goes without saying that the drain pipe 12 can be easily stored by utilizing both of these modifications, and in either case, the drain pipe 12 once stored in the space 14 cannot be easily taken out due to the restraining function of the locking member 13. .

The present invention has the structure and function described above, and by providing the locking member 13, the drain pipe 12 can be fixed horizontally or at a downward slope without moving up and down, and the drain can be discharged smoothly. Drainage can be cleared.

Moreover, the storage of the drain pipe 12 is carried out using the locking member 1.
This has the advantage of simplifying the work since all you have to do is insert it past the protruding part 3.
