Conventionally, there has been a problem of how to connect each member of the drainage device for the device that generates or allows drainage (hereinafter referred to as “drainage device”). This will be specifically described below.
The drainage pipe of the bathroom of the conventional example described in Patent Document 1 includes a bathtub, a bathtub pan, a washing pan, a bathtub pan drainer as a drain, a drain trap, a bathtub drain plug, and a bathtub drain plug as described below. And a bathtub piping for connecting the bathtub pan drainer, and a remote-operated drain plug device for remotely opening and closing the drain outlet of the bathtub.
The bathtub is a rectangular parallelepiped tank body that is open at the top, and is provided with openings at the upper edge (rim portion) and the bottom surface.
The bathtub pan is a tank body having an opening on the bottom surface called a waterproof pan on which the bathtub is mounted (the height of the side surface is low compared to the bottom area, but the four sides are covered with walls, so that drainage flows into the inside. Because it is configured to be a tank body).
The washing place pan is a waterproof pan (tank body) provided adjacent to the bathtub pan and washed by the user of the bathroom, and has an opening on the bottom surface.
The bathtub drainer is a substantially cylindrical member, and has a flange portion formed in the outer peripheral direction at the upper end, a bathtub drainage port formed therein, and a male screw formed on the side surface thereof.
The bathtub pan drainer is a drainer attached to the opening on the bottom surface of the bathtub pan, and has a bottomed substantially cylindrical main body part and a connection part for connecting to a drain trap described later on the side surface of the main body part. A female screw is provided on the inner peripheral edge of the upper part of the main body.
A drain trap is a drain that has a function to prevent odors and pests from flowing backward from the downstream side such as sewage to the upstream side such as indoors, and odors and pests flow backward from the downstream side. The function to prevent this is called a “trap function”.
The drain trap of this conventional example is a drain attached to the opening at the bottom of the washing place pan, and has an opening with a female screw on the upper side, Trap bodies each provided with a branch pipe part connected to the connection part of the bathtub pan drainage and a discharge port for discharging the internal waste water on the side surfaces,
The upper part is formed in a substantially cylindrical shape, and the upper part is watertightly connected to a later-described washing-house pan drainage outlet, and the lower end is constituted by a deodorizing cylinder disposed in the sealed water bottle part. In addition, the connection between the deodorizing cylinder and the bathtub pan outlet is provided with a rotation lock structure using an inclination at the upper end, and is fitted with a convex part of a washing place pan outlet described later to make watertight and packing. A detachable connection is made.
Furthermore, a deodorizing cylinder is connected to the washing pan drain. At this time, when the deodorizing cylinder is inserted so that the lower end of the deodorizing cylinder is placed in the sealed water bottle, and then the deodorizing cylinder is rotated, the rotation locking mechanism of the deodorizing cylinder is provided at the bathtub pan drainage port. It fits with the raised convex part and is connected in a watertight manner to the bathtub pan drain.
In addition, the bathtub pan drainer and drain trap are attached to the opening of the bathtub pan and wash basin pan, respectively, so that they have a substantially cylindrical shape and project upward outward along the circumference and on the outer surface of the cylindrical portion. Provided is a flange member provided with a male screw that is screwed with the female screw. The inner peripheral portion of each flange member forms a bathtub pan drain when attached to the bathtub pan, and a washing pan drain when attached to the washing pan.
Moreover, the cover member described below is watertightly provided at the bathtub pan drainage port.
The cover member is a member arranged so as to cover the bathtub pan drainage port, and allows the drainage on the bathtub pan to flow into the bathtub pan drainer and prevents a reverse flow from flowing into the bathtub pan drainer. , A bathtub connection port provided with a female screw to be screwed with a male screw of the bathtub drainer, and an insertion port through which a release wire of a remote-operated drain plug device to be described later is inserted.
The backflow prevention valve allows drainage to pass through the bathtub pan drainage port when the drainage flows from the bathtub pan into the bathtub pan drainer, and the drainage attempts to flow backward from the bathtub pan drainer onto the bathtub pan. In this case, it is a member that closes the bathtub pan drainage port and prevents the backflow of drainage.
In addition, there are backflow prevention valves that are normally open and closed only during reverse flow, and those that normally close and open only during drainage. The structure is also float type, swing type, lift type, self There are various structures such as a closed membrane type, but in any case of backflow, the valve is in contact with some member to close the flow path to prevent backflow. In this conventional example, as a backflow prevention valve, the bathtub pan drainage port is normally opened and the valve body flows back only when backflowing, so that the valve rises with the force of buoyancy or backflowing water and closes the opening. A flexible float type check valve is used. Specifically, a casing having an opening on the upper surface, a valve body having a specific gravity smaller than 1 that closes the opening during reverse flow, a guide shaft that guides the vertical movement of the valve body, and a packing provided on the casing side surface Thus, it is watertightly attached to the inlet of the cover member (in this conventional example, it is carried in a state attached to the inlet).
A remote-operated drain plug device is a drain device for opening and closing a bathtub drain opening provided in a bathtub drain device by a remote-control method, and includes an operation unit, a release wire, a support member, and a valve member described below. It consists of
The operation part is formed in a substantially cylindrical shape and attached to the opening at the upper edge of the tank body, and the bathtub drain is opened and closed by remote control.
The release wire is a cylindrical outer tube that is flexible in the lateral direction and rigid in the axial direction, and slides inside the outer tube. Wire, a valve shaft provided at one end of the inner wire, and a button provided on the opposite side of the valve shaft. It is composed of a holding mechanism (not described in Patent Document 1) that releases the fixation and pulls back the protrusion of the valve shaft portion.
The support member is a member that supports and fixes the release wire in the drain of the bathtub drain.
The valve member is a substantially disk-shaped member, and is configured such that the center portion of the lower surface is fitted to the tip of the valve shaft portion.

The bathroom drain pipe of the conventional example of the present invention configured as described above is constructed in the bathroom as follows.
First, the connecting part of the bathtub pan drainer is connected to the branch pipe part of the drain trap. The connection is made watertight using an adhesive.
Next, a drainage pipe (pipe pipe) on the sewage side is connected to the outlet of the drain trap. This connection is also made watertight using an adhesive.
Next, the cylindrical part of the flange member is inserted into the opening of the bathtub pan and the washing place pan, respectively, and is arranged so that the peripheral edge of the opening contacts the lower surface of the flange portion. Further, the female screw at the opening of the bathtub pan drainer is screwed into the male screw of the flange member at the bathtub pan side, and the female screw at the opening of the drainage trap is screwed into the male screw of the flange member at the washing station pan side. At the time of this connection, each flange member is rotated with a jig and screwed from above the pan. Although not specifically described in detail, a packing is disposed around the periphery of each opening and connected in a watertight manner.
Next, the bathtub drainer is inserted into the opening on the bottom surface of the bathtub, and the female screw of the cover member is screwed into the male screw to fix the bathtub drainer and the cover member.
Next, an operation unit is attached to the opening at the upper edge of the bathtub.
In addition, when connecting a bathtub drainer and an operation part, a packing is arrange | positioned to the periphery of each opening, and it connects watertightly.
Next, the release wire is connected to the operation portion, and the distal end portion of the release wire is inserted through the insertion port of the cover member.
Next, the release wire tip is pulled up from above the bathtub drain, and the release wire tip is placed and fixed in the bathtub drain (tub drain) by the support member, and the valve member is fitted to the valve shaft tip. And attach. After the completion of this operation, the insertion port is closed by packing while the release wire is inserted.
Next, the bathtub is placed on the bathtub pan, and the bathtub pan drain port is disposed so as to cover the cover member. Packing is arranged on the lower peripheral edge of the cover member, and the bathtub pan drainage outlet and the cover member are connected in a watertight manner (of course, when the bathtub is placed on the bathtub pan at an appropriate position at the time of design, the cover is covered). It shall be designed so that the member is placed in the proper location of the bathtub pan drain). This constitutes a flow path from the bathtub drain to the bathtub pan drainer.
Furthermore, a deodorizing cylinder is connected to the washing pan drain. At this time, when the deodorizing cylinder is inserted into the bathtub pan drainage port so that the lower end of the deodorizing cylinder is placed in the sealing water bottle, and then the deodorizing cylinder is rotated, the rotation locking mechanism of the deodorizing cylinder is The upper end of the deodorizing cylinder is watertightly connected to the bathtub pan drainage through a packing that is fitted to the convex portion provided in the pan drainage and is disposed on the lower surface of the rotation lock mechanism.
In this way, the construction of the drainage pipe in the bathroom including the bathtub, the bathtub pan and the washing pan is completed.

In the drainage pipe of the bathroom of this conventional example configured as described above, bath water can be stored in the bathtub by operating the remote-controlled drain plug device and closing the bathtub drain. After using the bathtub, when the push-in operation is performed on the button part arranged in the operation part of the remote-operated drain plug device, the holding mechanism acts and the valve shaft part is held and fixed in a protruding state. The valve member at the tip of the section is pushed up to open the bathtub drain, and the waste water in the bathtub is discharged from the bathtub outlet.
When drainage is generated from the bathtub, the drainage is discharged from the bathtub drainage port through the bathtub pan drainage, the connection part, the branch pipe part, the drainage trap, and finally from the drainage trap outlet to the sewage side through the drainage pipe. Is done.
At this time, a large amount of drainage flows into the bathtub pan drainer. However, since the backflow prevention valve functions and closes the bathtub pan drainage port (inlet), the drainage does not flow back onto the bathtub pan.
Moreover, since the insertion port is also closed by the packing, no backflow occurs on the bathtub pan from the insertion port.
From this state, when the pushing operation is again applied to the button part, the holding and fixing of the inner wire by the holding mechanism is released, the valve shaft part and the valve member are lowered, and the bathtub pan drainage port is closed.
Thereafter, by repeating this operation, the bathtub drain can be freely opened and closed by remote control.
In addition, when drainage occurs on the bathtub pan, the drainage from the inlet of the bathtub pan drainage port, through the bathtub pan drainer, connection part, branch pipe part, drainage trap, and finally from the drainage trap outlet It is discharged to the sewage side through the drain pipe.
In addition, when drainage is generated on the washing basin pan, the drainage is discharged from the washing basin drain through the drain trap and from the drain trap outlet to the drain through the drain pipe.
Moreover, when performing these waste_water | drains, the sealing water which is a reservoir part of waste_water | drain arises from the inside of a bathtub pan drainage device through a connection part in a waste_water | drain trap. This sealed water creates a trap function in the tub pan drainer and drain trap, and the tub drain, tub pan drain, and wash basin drain are sealed, and pests and odors from the sewage side to the indoor side are sealed. Inward backflow is prevented.
If it demonstrates concretely, drainage (sealed water) will accumulate by the utilization of a bathroom in the above-mentioned drainage piping of a bathroom to the upper edge of a sealing waterwell part in a sealing waterwell part.
For bathtub outlets and bathtub pan outlets, the inside of the connection and branch pipes is always full due to this sealing water, and is sealed against the piping on the sewage side, so odors and pests from the sewage side Does not flow backward to the indoor side.
For the wash basin drain, the lower end of the deodorizing cylinder is located inside the sealed water bottle, so from the bathtub pan drain to the inside of the deodorizing cylinder, between the outer surface of the deodorizing cylinder and the inner surface of the sealed water bottle, inside the drain trap. Since the part between the inside of the deodorizing cylinder and the outside surface of the deodorizing cylinder and the inside surface of the sealing basin is filled with water and sealed against the piping on the sewage side, the sewage side Odors and pests from the backwater do not flow back indoors.

Moreover, the connection location of each drainage device is watertightly connected by gluing or screwing via packing, and when properly connected, water leakage does not occur even if drainage is performed.

JP 2004-156362 A

As described above, each connection portion of the drainage device is performed by bonding or screwing through a packing.
Whether the connection is made by bonding using an adhesive or by screwing screws through packing, etc., in addition to the shape of the member, the location of use, the material of the drainage equipment, and cleaning and maintenance after construction It is selected depending on whether or not the drainage device needs to be separated.
For example, deodorizing cylinders and backflow prevention valves can be attached and detached even after completion of construction, such as bathroom users and cleaning. Or a rotation lock structure may be utilized like a deodorizing cylinder.
However, whether these connections are made at the construction site, whether by bonding or by screwing, it is difficult to make the connection properly and to verify that the connection has been made properly. .
The reason why the connection becomes difficult is that it is screwed from one side above (or below) the tank body as in the connection work between the bathtub drainer and cover member, flange member, bathtub pan drainer and drain trap. This is because when the drainage device or member is rotated, it is difficult for the operator's line of sight and hand to reach the lower side (or upper side) of the tank body. In addition, a jig for that purpose is also required for screw tightening work, but it is necessary to prepare a jig suitable for each member, and if there is no appropriate jig, for example, using a wrench, forcibly rotate This is because it is necessary to make a connection.
Further, depending on the work location, it may be necessary to put a hand in a narrow part, which also increases the difficulty of the work.
Also, the reason why it is difficult to verify whether the connection has been made properly is that the connection location is often in a narrow and deep place, and the place to check is not a factory but a construction site, In order to check whether the connection has been made properly, after closing the discharge port, etc., the drainage pipe including the drainage equipment is fully filled, and if there are water drops due to water leakage after a considerable period of time, etc. (For example, if the place to be inspected is a factory, and the size is easy to carry to some extent, close the opening, submerge it in the water tank, and send air into it.) It is also possible to make a simple and reliable confirmation that there is an air leak at the connection location (= a location where the connection is not watertight).
In addition, it is not a contractor with knowledge and experience, such as the above-described backflow prevention valve and deodorization cylinder, but the experience / knowledge of work is low (compared to the contractor) for places where general users attach and detach As a result, there is a low possibility that the connection is correctly performed, and it is difficult to understand and confirm whether the connection is properly performed, and there is a case where an incorrect connection may be performed.

The above-mentioned conventional example is an example related to the drainage pipe in the bathroom, but the same problem is not limited to the bathroom, but may occur when connecting various drainage devices such as a wash basin, a sink, a waterproof pan in a washing machine, a toilet bowl, etc. It is a problem.
