[Detailed description of the invention]

[0001]

[Industrial application] The present invention is to flexibly set the water sealing level of the drain pipe according to the static pressure of each air conditioner, etc., so that the drainage can smoothly flow through the drain pipe attached to the air conditioner. The present invention relates to a water sealing device that can be adjusted.

[0002]

2. Description of the Related Art As shown in FIG. 3, in a drain drainage facility such as an air conditioner, a drain pipe 13 for discharging drainage generated during operation of the drainage outlet to the outside is connected to a drain outlet of an air conditioner 12.
On the extension of the drain pipe 13, a water sealing pipe 14 for sealing the drain pipe 13 is usually communicated by trap construction.
By sealing the water, the drain flow was smooth. Conventionally, as shown in FIG. 4, this water sealing pipe 14 is formed by combining an elbow pipe 15 and a nipple pipe 16 so that the side face thereof is lowered.
By adjusting the length in the vertical direction, an optimum water sealing level is maintained in accordance with the static pressure of the air conditioner 12.

A drain pipe 2 for discharging waste water discharged from the air conditioner 12 or the like to the outside is disposed at a position of a discharge port at a tip end of the drain pipe 13. The base end of No. 2 penetrated the opening provided in the slab 1 and was positioned on the surface of the slab 1, and the surroundings of the opening were filled with repair concrete 17 or the like. Also this drain pipe 2
The receiving port is formed into a sleeve shape corresponding to the diameter of the drain pipe 13 and the amount of drainage, and a hopper 18 for guiding drainage from the drain pipe 13 to the drain pipe 2 is provided on the periphery of the receiving port.

[0004]

In the conventional water sealing pipe, the water sealing level in the water sealing pipe cannot be set to an optimum state in accordance with the static pressure of each device. For this reason, depending on the operating condition of the air conditioner, the drainage value may be exceeded due to overfilled water level, or the water level may be insufficient and the sealed water may run out, causing the odor to flow backward. Was. In addition, there is a problem that as the diameter of the drain pipe increases, it becomes more difficult to perform trapping with the pipe. further,
Since the drainage pipe is constructed by penetrating the slab, sleeve work for pipe penetration and repair work for the through hole are required. There was a risk of water leaking due to flooding. In addition, since the static pressure in the air conditioner depends on the route of the duct system, the calculated value and the current situation often differ,
Although it may be noticed that the difference is significant only after a trial run, there is a problem that the water sealing level cannot be easily adjusted once the conventional water sealing pipe is set.

Accordingly, an object of the present invention is to provide a water sealing device capable of easily adjusting an appropriate level of water sealing according to the static pressure of each device such as an air conditioner.

[0006]

SUMMARY OF THE INVENTION The present invention is a variable water sealing device which achieves the above object. It accommodates the tip of the drain pipe that communicates with the drain port of the air conditioner and the like, and seals the drainage discharged from the air conditioner and the like via the drain pipe. It comprises a fixed pipe provided upward and capable of communicating with an external drain pipe, and a movable pipe provided up and down in the fixed pipe. In addition, it is preferable that the movable pipe is provided with a scale for measuring the water sealing level on the outer periphery in the longitudinal direction, and that the upper peripheral edge is formed in a bell-mouth hopper shape.

[0007]

According to the variable water sealing device of the present invention, when the air conditioner is driven, drainage from the air conditioner flows out through the drain pipe into the water sealing tank, and this drainage is received at the upper end of the telescopic pipe provided in the water sealing tank. From the pipe, and is discharged outside through a fixed pipe and an external drain pipe sequentially. At this time, the sealing level in the sealing tank is
Since the moving pipe can be moved up and down so as to be within the allowable water sealing level of the drain pipe, it can be adjusted according to the static pressure of the air conditioner.

In addition, since a scale for measuring the water sealing level in the water sealing tank is provided in the longitudinal direction of the moving pipe, the water sealing level corresponding to the static pressure of each air conditioner is calculated so that the water moving level is calculated in advance. By moving the pipe up and down, the water sealing level of the water sealing tank can be set. For this reason, it is possible to prevent various sudden accidents such as overflow from the receiving port of the water sealing tank that occur during the trial operation of the air conditioner. Furthermore, since the upper peripheral edge of the moving pipe is formed in a bell-mouth hopper shape, the inflow of drainage into the moving pipe is promoted.
