[Industrial applications]

 This invention is mainly a drainage pipe connecting plate that arranges a trap mechanism provided in a cabinet such as a sink or a washbasin in a general household and the drainage pipe so that the space inside the cabinet can be used rationally. Regarding the improvement of.

[0002]

[Prior art]

 In the conventional sink cabinet, as shown in Fig. 4, the sink (b) of the sink (b) in the cabinet (b) has a slag basket (d) hanging down, and the back plate (e) of the cabinet (b). The inner surface has a certain running water gradient in advance, a plurality of branch pipe mounting parts (f) are formed in a projecting manner, and a trap part (h) is bent between the lower end outlet (g) and Fix the concentrating pipe (i), and connect the above-mentioned residual basket (d) and the branch pipe mounting part (f) of the concentrating pipe by the upper drain pipe (nu), and the outlet (g) at the lower end of the concentrating pipe and the floor plate drain port ( The lower drainage pipe (e) to connect the drainage pipes (b) to the lower drainage pipe (e). In this case, the bowl-shaped trap formed on the inside of the cabinet is omitted and the storage space inside the cabinet is effectively used. It is known by actual Sho 50-38300 Patent Publication according to human application.

[0003]

[Problems to be solved by the device]

 Thus, a water supply pipe (F), a gas pipe (Y), etc. are installed inside the back wall (W) of the back plate (E) of the conventional cabinet (B) of this type. Although the window for checking the condition is opened for the maintenance, the back wall (e) is fixed in the cabinet such as the sink with the above configuration, so the back wall is fixed. There was a problem that the cabinet (a) had to be moved every time to check the piping (f) (yo) in (w).

Further, since the conventional collecting pipe provided on the back plate is provided with a predetermined flowing water gradient on the upper portion, the trap mechanism is small in proportion to the area of the entire mechanism being large, and the trap function is large. The problem was that the

[0005]

[Means for Solving the Problems]

 In view of such circumstances, the present invention has a cabinet type sink with a lower part of a sink, and a back plate of the cabinet is provided with a window hole communicating with an inspection window on the back wall of the body, and the window hole is closed. A guide wall that bends in an S-shape in the horizontal direction is installed opposite to the front surface that connects one diagonal of the enabled board, and the flexible space is secured along the guide wall between the sink-side drainage port and the underfloor drainage port. A drainage pipe is used for connection, and a trap mechanism is formed in this part.

In addition, near one diagonal of the above substrate, a connection port for the upper drain pipe and a connection port for the lower drain pipe are projected, and the connection ports are connected by a lateral S-shaped water passage to trap the trap. We also adopted the means of forming

[0007]

[Action]

 The present invention has a special function in which the trap function is formed on the window plate that can be attached to and detached from the cabinet back plate, so that the inspection and repair of the in-body piping can be performed by a simple work simply by removing the substrate. To have.

In addition, since the trap mechanism is curved diagonally in one diagonal direction of the window plate from its upper part to its lower part in a horizontal S-shape, a sufficient height difference can be obtained. It has a characteristic effect of further improving.

[0009]

【Example】

 Hereinafter, the structure of the connection plate of the present invention will be described in more detail according to the first and second embodiments.

First Embodiment In FIG. 1, 1 is a sink cabinet main body, 2 is a back plate formed by penetrating a window hole 2 ′ for pipe inspection, and 3 is a water supply or a water supply disposed inside the body. Inspection windows for piping 3 ′ such as gas pipes, 4 is a sink in which a slag basket 4b is hung vertically from a drain port 4a, 5 is an underfloor drain port, and 6 is a drain outlet 4c of the drain port 4a or the slag basket 4b. A flexible drainage pipe that connects the underfloor drainage ports 5 and a connection plate 7 described below.

As shown in FIG. 2, the connecting plate 7 is a diagonal of the surface of the substrate 7a having a size capable of covering the window hole 2 ′ penetrating the back plate 2 of the cabinet. A pair of lateral S-shaped guide walls 7b into which the flexible drainage pipe 6 can be fitted are projected from a position close to the portion.

Reference numeral 7 c in the drawing is a stopper which is provided at an appropriate position on the guide wall so that the drain pipe 6 can be locked, and 9 indicates a mounting hole to the back plate 2.

Further, the connection plate 7 in the above-mentioned embodiment is made of plastic by injection molding, but the material is not limited to the plastic material, and the guide walls 7b and 7b are Since the purpose is to guide the flexible drainage pipe 6 in a horizontal S shape, it is provided continuously from beginning to end as shown in FIG. Good.

Second Embodiment Next, 8 shown in FIG. 3 is another embodiment of the connection plate of the present invention, the substrate 8a of which is a window hole of the cabinet back plate 2 as in the first embodiment. 2'has a size capable of covering 2 ', and is provided with projecting connection ports 8b, 8c close to a diagonal portion on the inner surface side thereof and capable of connecting upper and lower drainage pipes, while between the two connection ports 8b-8c. Are connected by a horizontal S-shaped water passage 8d.

It should be noted that it is optional whether the horizontal S-shaped water passage 8d is provided on the front surface or the back surface of the substrate 8a, or in the middle of the front surface and the back surface of the substrate. It is preferable to manufacture the polyethylene material by a plow molding method.

Further, the connecting plate is connected to the drainage outlet 4a of the sink such as a sink cabinet directly or between the drainage outlet 4c of the slag basket 4b and the connection inlet 8b on the upper side of the substrate by the upper drainage pipe, and further on the lower side. By connecting the connection port 8c and the underfloor drainage port 5 with a lower drainage pipe, a clap function can be given to the water passage 8d. Further, 8e is a drain outlet provided at the bottom of the water passage 8d as necessary, and 9 is an attachment hole for the back plate 2.

[0017]

[Effect of device]

 As described in detail above, the drainage pipe connection plate of the sink cabinet according to the present invention has an extremely simple structure, but it has the functions of the drainage pipe and the drainage trap inside the cabinet such as the sink and washbasin. This makes it possible to effectively use the internal space of the cabinet, and even when performing maintenance and inspection of the water supply pipes and gas pipes that are piped inside the body, the back plate of the cabinet and the substrate of this connection plate It is possible to carry out repairs and maintenance simply by removing the.

Further, the connecting plate having the above structure can be provided at a low cost, and can be easily attached to an existing sink cabinet or the like in each home or the like, and its utility value is extremely large.
