Description

  The present invention relates to a drainage device for draining drainage equipment such as a water tank, a sink, a sink, and a floor.

As shown in FIG. 6, the following drainage devices are known as drainage devices for draining drainage equipment such as water tanks, sinks, washstands, and floors.
The drainage device of FIG. 6 includes a tank body, a drainage body, a male screw body, a fixing nut, a packing, a discharge pipe, a pipe, and a drain trap described below.
The tank body is provided with a drain outlet at the bottom and is provided in a sink.
The drainage device main body is made of a metal material such as stainless steel, and includes openings at the top and bottom, and a flange portion that protrudes outward from the opening at the top.
The male screw body is made of synthetic resin, is formed by screwing a male screw on the outer periphery, and is integrally formed with the drainage body by caulking.
The fixing nut is an annular body having an inverted L shape in cross-section, and constitutes an internal thread that engages with the external thread of the external thread body on the inner periphery.
The packing is a member disposed between the flange portion and the drainage port of the tank body, and is disposed in order to make the space between the flange portion and the tank body watertight.
The discharge pipe is connected to the opening at the bottom of the drainage device main body, and is a member for draining the drainage in the drainage device main body to the pipe.
The pipe is a member for discharging the drainage from the discharge pipe to a drain trap described later.
A drainage trap is a member attached in the middle of piping, and is a member which discharges drainage from piping to sewage. Moreover, a sealing water is comprised in the inside so that pests and odors may not flow back into the room from the sewage.

The above-described conventional drainage device is attached as follows.
After the flange portion of the drainage device main body is brought into contact with the drainage port of the tank body through packing, a fixing nut is disposed from the back surface of the tank body, and the male screw body and the female screw part are screwed together. Thereafter, the discharge pipe is connected to the opening of the drainage device main body, and connected to the drainage trap through the pipe.
The drainage in the tank passes through the drainage device main body, flows through the drainage trap through the discharge pipe and the piping, and is finally drained into sewage.

  In the conventional drain trap, the drainage body is made of metal, so that the design is improved. In addition, since the screw portion that is difficult to be made of metal is made of synthetic resin, the drainage device can be made cheaper and easier to manufacture than the drainage body made entirely of metal.

Further, there has been a technique for forming a drainage body having a shape that cannot be molded by an injection molding die structure by molding the drainage body by blow molding. In this case, there are many merits such as that the drainage trap body itself can be integrally provided with the drainage trap.

However, the above-described conventional drainage device has the following problems.
Usually, the drainage device drains the wastewater from the tank body or the like, but the content of the drainage varies depending on whether it is room temperature tap water or hot water.
The conventional drainage device is made of a metal such as copper or stainless steel plate, but the metal has a very good heat transfer property. Therefore, when draining hot water or hot water in particular, the drainer body is warmed. However, as soon as drainage is completed, it is rapidly cooled by external air, and water vapor in the air adheres as water droplets to the surface of the drainage device (the side where drainage does not pass) (hereinafter referred to as condensation). Was.
When dew condensation occurs in the drainage device body, the humidity in the cabinet where the drainage device is placed and the piping under the floor rises, causing mold and the like.
In addition, when the water droplets of dew condensation adhering to the drainage device drop on the floor surface in the cabinet and the floor surface is made of wood or the like, the floor surface may corrode in the worst case.
In addition, since conventional drainage equipment manufactures steel plates such as stainless steel and copper by pressing, the only way to open the drainage is to open the bottom of the drainage body facing downward, and of course the drainage The discharge pipe had to be extended downward with respect to the main body. Since the piping and the drain trap are arranged below the drainage device main body, the inside of the cabinet is divided, each space becomes very narrow, and the storage space in the cabinet is reduced.
In addition, pipes and drain traps are attached to the drain pipe of the drainage device body, but sealed water is always stored in the drain trap, and furthermore, drainage passes through the inside, so the drain pipe is equivalent to drainage. A heavy load will be applied.
In the above-described drainage device, when the discharge pipe is made of metal, it is difficult to screw a screw into the discharge pipe. Therefore, the pipe and the discharge pipe may be connected by bonding. When it was made of metal, it was difficult to bond strongly enough to withstand the load of drainage in the pipe and drainage in the drain trap because of adhesion between different materials of metal material and synthetic resin material . For this reason, in the worst case, the piping and the drain trap may fall off during use.
Also, a method for performing a screwing connection, such as screws, in case where the exhaust pipe is made of synthetic resin, the opening of the bottom part of a conventional water trap body and said, constituting the bother synthetic resin discharge pipe The number of members such as nuts and packings for attaching the discharge pipe and the drainage device body is increased, which inevitably increases the cost.

  Also, if the drainage device body is blow molded, due to the characteristics of blow molding, variations in thickness and irregularities are likely to occur, the design of the drainage device is poor from the viewpoint from the top of the tank body, Drainage and water were likely to collect on the uneven parts and the unevenness of the inner surface, and the cleanability was poor.

  The drainage device of the present invention is designed to improve the design, prevent condensation of the drainage device, effectively utilize the space in the cabinet, and to be a connection method that can withstand the load of the piping and drainage trap, It was invented to solve the problem of reducing the number of points and making them inexpensive.
