Description

[Detailed Description of the Invention] This invention relates to a drainage device for a general household washing machine that is suitable for cold regions such as Hokkaido.

Drainage devices for washing machines are generally used only once a day, and when they are not in use, such as at night, there is no water flow, and the wastewater for odor control remains stationary in a trap in the middle of the drainage channel. ing.

The trap is usually located in a space below the floor and exposed to the outside air.

For this reason, in cold regions such as Hokkaido, there is a problem in that the sealed water in the trap freezes during the winter, making it impossible to drain water the next day.

Conventionally, the water seal traps located under the floors of buildings were covered with thick insulation material, but this did not have much effect.

This idea was created in view of the above circumstances, and its purpose is to cover the water sealing trap where water remains with insulation material and to bury it underground under the floor of the building to ensure protection from the low-temperature outside air. Another object of the present invention is to provide a water sealing trap that can completely prevent residual water from freezing.

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

In the figure, reference numeral 1 indicates a floor of a general household building, for example, which is constructed by pasting a soft floor 3 on a board 2, and has mounting holes 4 passing through it vertically.

Reference numeral 5 denotes a drainage device installed in the mounting hole 4 of the floor 1, and the end of the drain hose (not shown) of the washing machine is inserted into the drainage device main body 6, which has a shape that gradually increases in diameter from the bottom end to the top end. A removably insertable hose holder 7 is fitted and fixed by a holder presser 8, and an odor-proof cap 9 is attached to the upper end.
It has a structure in which it is removably fitted.

Reference numeral 10 denotes a straight connecting pipe which is suspended below the floor 1 by connecting its upper end to the lower end opening of the main body 6 of the drainage device 5;
Reference numeral 1 denotes a deodorizing water sealing trap 13 called a P-trap connected to the lower end of the connecting pipe 10 via a socket 12.
A drain pipe is connected to the outlet end of the water sealing trap 11 via a socket 14, and the end of the drain pipe 13 is connected to a sewer (not shown) or the like.

Further, numeral 15 in the figure is a heat insulating material provided to cover the entire outer periphery of the water sealing trap 11.

The heat insulating material 15 is a molded product made of polystyrene foam, for example, and has a so-called two-piece structure, with a recess formed inside to form a socket 12, a trap 11. The socket 14 is inserted and covered from both outside sides.

In a drainage system having such a structure, a connecting pipe 10 hanging below the floor 1 is formed to be long so as to extend further downward from the ground A below the floor 1, and a water sealing trap 11 connected to the lower end of the connecting pipe 10 is formed to be long. Together with the heat insulating material 15 that covers the outer periphery, it is installed at a position about 2 meters lower than the ground A, that is, a position buried deep underground where it is not affected by the low-temperature outside air.

Naturally, the discharge pipe 13 is also buried underground and connected to the sewer through the underground.

Further, it is preferable that the heat insulating material 15 is impregnated with an asphalt-based filler in advance or its surface is covered with a waterproof film so that it does not absorb moisture underground.

The connecting pipe 10, socket 12, 14, and drain pipe 13 are made of vinyl chloride or the like.

Therefore, in the drainage device of this invention, when using a washing machine, the deodorizing cap 9 on the main body 6 of the drainage device 5 is removed, and the washing machine is inserted into the hose holder 7 in the main body 6 from above the floor 1. Insert the end of the drain hose to drain water.

The drainage water falls through the connecting pipe 10 from inside the main body 6 of the drainage device 5, and the person falls into the water sealing trap 11.
The water is discharged to the sewer through the drain pipe 13 while a predetermined amount of sealed water always remains inside.

When the washing machine is no longer used and draining is completed, the hose is removed and the deodorizing cap 9 is returned to its original position.

When not in use, a portion of the drainage water is stored in the water sealing trap 11.
If this remains in the water and freezes due to the cold weather at night, it will be impossible to drain it the next day, but in this device, the water sealing trap 11 is covered with a heat insulating material 15 and is buried deep underground. For example, -20℃
Even when the outside air drops, the water sealing trap 11 is not affected by the low temperature outside air, and therefore the water sealing trap 11 is kept warm and the residual water therein is reliably prevented from freezing.

In addition, if the insulation material 15 is waterproofed with an asphalt-based filler or waterproof film, the insulation material 15 will not absorb moisture from the ground, and the insulation effect will be maintained even in severe cold seasons when the ground freezes. not be damaged.

This invention, as described in detail above, is capable of reliably protecting it from low-temperature outside air by burying the water injection trap in which water remains underground and covering it with a heat insulating material. It can completely prevent freezing, making it extremely advantageous as a drainage device for washing machines in cold regions such as Hokkaido.
