Abstract

PROBLEM TO BE SOLVED: To prevent shortage of waterseal and loss of a cover by fixing a fixed drain perforated plate in the upper end opening of a floor drainage cylindrical hardware body, at which a bell trap is provided and making openable the drain opening of the fixed drain perforated plate by a rotary perforated plate. SOLUTION: When holes 9C, 9D are positioned to face holes 8A, 8C by turning a rotary perforated plate 9, an opening/closing device 11 constituted of a fixed drain perforated plate 8 and the rotary perforated plate 9 is brought to an opened state and drain on a floor can be guided to flow in a cylindrical body 2. That is, when there is drain on the floor, the opening device 11 is set in the opened state to supply a part of the drain on the floor to an annular space 4 for waterseal 5. When dashing drain on the floor, the opening device is set in the closed state. In this way, waterseal 5 can be prevented from decreasing owing to evaporation and further, even when the bell trap 7 can not bring out its function because of decrease of the waterseal, the opening/closing device 1 can effectively prevent from intrusion of odors from a drain pipe 3 and intrusion of small animals into the indoor side.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor drain fitting with a rotary switchgear.

[0002]

2. Description of the Related Art Conventionally, when water from a floor is poured into a sewage pipe, a floor drain metal is buried in the floor, a drain pipe is connected to the floor drain metal, and a bowl-shaped trap is provided in the floor drain metal. By storing a part of the floor drainage as seal water, the flow of air between the drainage pipe and the room is shut off, thereby preventing odors, insects, etc. from entering the room from the sewage pipe.

[0003]

However, if there is no floor drainage for a long period of time, the sealing water in the bowl-shaped trap evaporates, and the effect of blocking odors and the like is lost, so that odors and insects enter from the sewage pipe and the like. Will forgive. The problem is, for example,
It is likely to occur particularly in applications where water is not drained for a long period of time, such as general toilets, hotel unit baths, and unused apartment unit baths. In addition, in a room where the frequency of floor cleaning is low in a food or a pharmaceutical factory, etc., running out of water is a serious problem not only from odor and insect invasion but also from the viewpoint of hygiene and prevention of contamination.

Conventionally, a removable lid is provided on floor drainage hardware to prevent odors or the like from entering the room even if the sealing water is broken, but the lid is lost. There were many problems in terms of management.

[0005] It is an object of the present invention to provide a floor drain fitting with a rotary switchgear which can solve the above-mentioned problems in the prior art.

[0006]

The feature of the present invention to solve the above-mentioned problem is that a bottom portion is connected to a sewage pipe or the like,
A floor drainage fitting comprising a bowl-shaped trap that uses a part of floor drainage as sealing water in a cylindrical main body disposed so that an upper end opening thereof matches a floor surface level, and is fixed to the upper end opening. The present invention is characterized in that the drainage plate is fixed, and a rotating plate for opening and closing the eyes of the fixed drainage plate is attached to the fixed drainage plate.

[0007] An opening / closing device for opening and closing the upper end opening is constituted by the fixed drainage pan and the rotary pan. Since the fixed drainage plate is fixed to and integrated with the upper end opening of the cylindrical main body, there is no risk of loss.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a sectional view showing an embodiment of a floor drainage hardware according to the present invention, and FIG. 2 is a plan view thereof. The floor drainage hardware 1 has a cup-shaped tubular main body 2,
The tip 3A of the sewage pipe 3 is connected to the bottom wall 2A. The distal end portion 3A extends into the cylindrical main body 2, whereby the outer peripheral surface 3Aa of the distal end portion 3A and the inner peripheral surface 2B of the cylindrical main body 2 are formed.
An annular space 4 is formed between them and a part of the floor drainage is stored therein as a sealing water 5. In order to prevent the odor from the sewage pipe and small animals from entering the room by using the water sealing 5, a bowl-shaped trap member 6 is covered on the distal end portion 3A. Is formed with a bowl-shaped trap 7 having a known configuration.

The cylindrical body 2 has an upper opening edge 2C having a floor F.
Is buried in the floor F so as to match the level of the floor FA of the cylindrical body 2.
It is designed to flow inside.

A fixed drainage plate 8 having holes 8A to 8D for passing the floor drainage is fixed to the upper opening edge 2C. Then, the fixed drainage dish 8 has holes 8A-
A rotating plate 9 for opening and closing 8D is concentrically arranged. The rotating eye 9 is rotatably mounted on the fixed drain 8 by a connecting shaft 10, and the rotating eye 9 has holes 9 </ b> A opposed to the holes 8 </ b> A to 8 </ b> D of the fixed drain 8.
To 9D.

Therefore, the rotating plate 9 is rotated so that the hole 8
If the holes 9A to 9D are opposed to A to 8D, the fixed drainage dish 8
The opening / closing device 11 composed of the rotary plate 9 and the rotating plate 9 is in an open state, and floor drainage can flow into the cylindrical main body 2.
On the other hand, if the drain holes 8A to 8D and the holes 9A to 9D do not face each other (the state shown in FIG. 2), the opening / closing device 11 is closed.

As a result, when there is floor drainage, the opening / closing device 11 can be kept in an open state, and a part of the floor drainage can be supplied to the annular space 4 as the sealing water 5. On the other hand, when drainage is not allowed to flow to the floor, the opening and closing device 11 is kept in a closed state, whereby a decrease due to evaporation of the sealing water 5 can be suppressed, and the sealing water 5 decreases, and the bowl-shaped trap 7 becomes Even when the function cannot be fulfilled, the opening and closing device 11 can effectively prevent the odor from the sewage pipe 3 and small animals from entering the room.

In this configuration, since the opening / closing device 11 constituted by the fixed drainage plate 8 and the rotating plate 9 is fixed to the upper end opening of the cylindrical main body 2, the opening / closing device 11 serving as the opening / closing lid is lost. And management is reliable and easy.

[0015]

According to the present invention, a fixed drainage plate is fixedly provided at the upper end opening of the cylindrical body of the floor drainage hardware provided with the bowl-shaped trap, and the drainage hole of the fixed drainage plate is rotated. Since the lid is opened and closed by a perforated plate to provide a function as an opening / closing lid, this can solve the problem of running out of water and eliminate the loss of the lid, so that the management is reliable and easy.
