JP3003368U - Low noise drainage pipe - Google Patents

Abstract

(57) [Abstract] [Purpose] It is considered that the frequency of using flush toilets at midnight will increase as a result of going to an aged society.
A pipe shape that reduces the sound of falling water from the flush toilet from the upper floors without being distracted by an apartment house. [Composition] Heating pipes such as PVC currently in use, the falling water flow,
It was shaped so that it could fall obliquely on the inner surface opposite to the bend.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drainage mechanism necessary for construction, and relates to a shape of a metal or plastic pipe that reduces drainage noise at night.

[0002]

[Prior art]

 Conventionally, a drain pipe at the time of construction uses a simple straight pipe regardless of the material. Although it is economically easy in terms of work, it does not consider the noise of drainage at night, whether it is an individual or an apartment house, at all. Therefore, drainage noise generated from toilets and baths in the middle of the night often causes trouble. If the wastewater falls in a straight pipe, the reverberation sound on the way and the bottom arrival sound reverberate with each other and generate unexpectedly large noise. In recent years, remarkable progress has been made in electronic devices, etc., and improvements in the housing environment such as kitchen appliances, warm-cleaning toilet seats, and hot water distribution have made unexpected progress, but most of the basic drainage pipe materials are It does not progress and remains a straight pipe. Even for fluorescent lamps, we have pursued the convenience of bending from a straight tube, and have come to a completed shape. In the coming aged society, there is a great need to reduce the noise of drainage water that is inevitably generated, such as nighttime sleep and bathing after returning home at night in an apartment house. The bent pipe of the present invention significantly reduces drainage noise depending on its use and contributes to the formation of a quiet living environment.

[0003]

[Problems to be solved by the device]

 A drainage mechanism is absolutely necessary for residential construction, and drainage on the upper and lower floors must pass around the inner wall of the living space regardless of whether it is low or high. As a result, drainage noise is generated, which causes an awakening sound at midnight and the like, which may cause a battle between the upper and lower floors. According to the present invention, a currently used vinyl chloride or metal pipe is bent into an equidistant S-shape as shown in Fig. 1. With this shape, a water drop at the center of the pipe also comes into contact with the inner slope of the bend. , You can turn off the sound of tapping. By using this pipe, even in the middle of the night toilet and bathing, the drain noise can be lower than that of the straight pipe drain.

[0004]

[Means for Solving the Problems]

 In the case of the currently used vinyl chloride pipe, at the moldable temperature before curing, it is sandwiched by sandwiching metal fittings having protrusions at equal intervals on the flat plate and molded into a shape as shown in FIG. Also, for small-scale molding such as trial production, the protruding wood pieces are fixed on the plywood board at desired intervals, and the vinyl chloride pipe before hardening temperature is manually molded into a gentle S shape, and the effect of the present invention It is possible to obtain materials that satisfy the requirements. With this configuration, the drop drainage always falls vertically on the gentle slope, and it is possible to reduce the interference noise in the middle of the pipe and the tapping noise at the right angle portion.

[0005]

[Action]

 By using the gentle S-shaped pipe of the present invention in the falling water channel of the drainage mechanism on the upper and lower floors of the building, the falling water always hits the gentle slope and the contact noise, interference noise, tapping noise, etc. are reduced. The sound of drainage that is reminiscent of a toilet, unnecessary consideration for bathing at midnight, and the cause of trouble can be prevented.

[0006]

【Example】

 In the construction of the drop drainage system, the drainage sound can be drained by using the generous S-shaped pipe of the present invention instead of a single straight pipe at a position where the drainage sound has some effect on life feelings. The noise can be reduced. In that case, the required area is required because it is S-shaped than the occupied area where the straight pipe exists, but in the concrete system, it is installed in a central hole for electricity, water supply and drainage, and in the case of wooden construction. However, installing rafters between the interior walls or between the onukis has a lot of space, and there is no obstacle in terms of work.

[0007]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. At the time of construction, unpleasant or unnecessary drainage noise can be prevented by using a conventional straight pipe for the drainage pipe of the drainage mechanism and using the loose S-shaped pipe of the present invention.

FIG. 2 shows a state in which a drop of drainage water or the like comes into contact with a gentle slope.

Claims (1)

[Scope of utility model registration request] 1. A pipe having a shape that alternately bends the pipe so that water drops falling from the center point of the pipe come into contact with the inner slope of the bent portion and reduce the sound of falling water during drainage.
