Description

[Detailed description of the invention] [Industrial application field] This invention enables the connection of a drain hose and a drainage pipe such as a hard PVC pipe during the installation work of an air conditioner without impairing the workability of conventional installation work. This invention relates to an improvement in a drain hose that can be installed even in wall-embedded piping.

[Conventional technology]

A conventional air conditioner is constructed as shown in FIG. Moisture contained in the airflow sucked in by the fan 1 during cooling is cooled as it passes through the heat exchanger 2.
It is condensed and generates water droplets in the heat exchanger 2. This water is collected by a drain pan 3 at the bottom of the heat exchanger 2 and drained to the outside of the building by a drain hose 5a connected to the drain pan 3 through a socket 4. This drain hose is a soft PVC hose 6 with an appropriate length.
and a socket 7 that is watertightly connected to its tip.
, a heat insulating material 8 that covers them, and an adhesive tape 9 that fixes the heat insulating material.

Next, an example of drain installation for a wall-mounted air conditioner using the above drain hose will be explained. As shown in FIG. 6, a wall hole sleeve 11 is installed at a place where a hole is made through the wall 10. Drain hose 5 there
Take it out to the outside of the building through a. Outside the building, the socket 7 and the drain pipe 12 are connected to drain the condensed water generated from the heat exchanger 2 of the indoor unit to an appropriate location. The drain hose 5a and the drain pipe 12 are both fixed to the outer wall with clamps 13.

[Problem that the invention attempts to solve]

Since the conventional drain hose is constructed as described above, when the drain pipe 12 is designed to be embedded in a wall, it becomes as shown in FIG. 4. Drain pipe 12 and drain hose 5
The connection to the drain hose 5b must be made at an appropriate position on the back of the indoor unit 14 in order to prevent the drain hose 5b from sagging, reverse slope, etc., and for ease of service after installation. In that case, the length of the conventional drain hose 5a cannot be adjusted, and the soft PVC hose 6a
When the drain pipe 12 was cut, connection with the drain pipe 12 was impossible. Furthermore, if the conventional drain hose 5a is simply shortened, a drain hose 5c as shown in FIG.
and the connection part of the drain hose 5c is on the indoor side or
Depending on the location of the wall hole, it may end up in or near the wall hole, which may impair installation work or cause water leakage inside the room.

This idea was made to solve the problems mentioned above, and is useful when connecting a drain hose to a drain pipe outside a building (using a long drain hose) or when installing pipes embedded in a wall. The aim is to create a drain hose that can be connected to a drain pipe at the back of an indoor unit (by adjusting its length to a shorter length), without sacrificing conventional workability or safety against water leaks. shall be.

[Means for solving problems]

The drain hose according to this invention has a hollow cylindrical shape that can be connected to a drain pipe by cutting it at a designated position as shown in Figure 3, and the hose can be connected to both ends, with the middle part mating with the drain pipe. An intermediate socket with a diameter such as that shown in FIG.

[Effect]

Since the length of the drain hose in this invention can be adjusted in multiple stages by cutting the intermediate socket at a designated position, the connection position with the drain pipe can be selected in multiple stages.

[Example of idea]

An embodiment of this invention will be described below with reference to the drawings. As shown in Figure 1, the drain hose 5 consists of a flexible drain pipe 6 made of soft vinyl chloride or the like of appropriate length, a socket 7 watertightly glued to the tip, and a heat insulating material 8 covering them. It is composed of an adhesive tape 9 for fixing and an intermediate socket 15 provided in the middle. As shown in FIG. 2, the shape of the intermediate socket is a hollow cylindrical shape that is watertightly molded of plastic or the like, and is formed by sandwiching the intermediate portion 19 between the connecting portions 16 at both ends. It has a shape that allows for a watertight plug-in connection. Reference numeral 17 denotes a stopper, which is formed in a ring shape to protrude between the connecting portion 16 and the intermediate portion 19 so that the flexible drain pipes 6 on both sides are inserted into and abutted against the connecting portion 16 to position the flexible drain pipes. . Reference numeral 18 denotes a cutting groove for drain piping construction, which has a V-shape for easy cutting, and is formed so that the cut portion 18a has a tapered shape after cutting. The intermediate portion 19 has an outer diameter that fits into the hard drain pipe 12, and is connected and fixed using an adhesive to maintain watertightness. It is now possible to do so.

Moreover, this intermediate socket 15 is symmetrical on the left and right sides,
Fitting is possible even if the connecting portion 16 on either side is toward the tip of the drain hose 5, and since it is covered with a heat insulating material and cannot be seen from the outside, the position indicating mark 20a such as a label 20 can be placed on the outer surface of the heat insulating material 8. The presence of the intermediate socket 15 is clearly shown in the figure.

In the drain hose 5b configured as described above, by cutting the intermediate socket 15,
The connection position can be adjusted in two stages without impairing the connection function with the drain pipe, and the procedure will be explained below. First, using the label 20 or other markings pasted on the heat insulating material as a guide, cut only the heat insulating material 8 and confirm the position of the intermediate socket 15. After checking, cut the insulation to expose the intermediate socket. Next, the V-shaped groove on the distal end side of the intermediate socket 15 is cut with a saw or the like. Remove any burrs from the cut surface and insert it into a drain pipe with a matching inner diameter. At that time, use adhesive or the like to maintain watertightness. After testing the connections for water leakage, insulate the necessary areas to prevent condensation. In this way, the connection position of the drain pipe and drain hose can be adjusted.

[Effect of idea]

As explained above, this idea allows the length to be adjusted in multiple stages by providing an intermediate socket in the drain hose of an air conditioner, and without compromising the installation workability of conventional drain hoses, it can be easily attached with labels, etc. By simply modifying the marked drain hose, it can be used for any type of piping connection, including conventional methods for taking out drain from the indoor unit to the left, right, or rear, as well as wall-embedded piping connections.
