Description

[Detailed description of the invention] Industrial application field: This invention relates to a floor drainage device installed on the floor of a toilet, bathroom, office, etc.

Conventional technology: A trap acting part (a water seal that prevents odor from the drain pipe side from entering the room) is created in the vessel by a riser pipe that communicates with the drain pipe and a bell-shaped body into which the riser pipe enters. Part) The floor drainage equipment formed is
It is called a belt trap, and because it has a simple symmetrical structure, it is widely used as a floor drainage device.

Problems the invention seeks to solve: Belt traps are widely used because of their manufacturing advantages, but they are prone to clogging. The term "clogging" here refers to a significant increase in flow path resistance due to the growth of sediment above the trapping area and an increase in the layer thickness of sediment such as sand, cement, dust, etc. on the bottom of the vessel. Point. When a clog occurs, disassembly and cleaning is used to clear it, but disassembling and cleaning is a troublesome task.

Means for Solving the Problems: In order to solve the above-mentioned problems with belt traps, the present invention interposes a means for restraining the rotation of the bell-shaped body between the bell-shaped body and the container body, and a slot on the perforated plate. A shaft connected to an operating handle stored in the container is rotatably supported by a perforated plate, and a cleaning plate having a bell-shaped body forming a trap action section, an action edge for the riser pipe, and an action edge for the bottom of the container body. The cleaning plate is characterized in that the shaft provided inside the body and connected to the operating handle and the cleaning plate are drivingly connected to the shaft via an interlocking portion that allows movement in the vertical direction.

Operation: The cleaning plate is operated by applying rotation to the shaft via the operating handle. The cleaning plate scrapes off the deposits on the trap action part and makes it floating. When the cleaning plate is rotated, water is poured through the perforated plate, and the scraped off deposits are sent into the drain pipe in a floating state.

Embodiment: Figure 1 is a vertical cross-sectional view showing an example of the floor drainage device according to the present invention, Figure 2 is a cross-sectional view taken in the - line direction of Figure 1, and Figure 3 is a cross-sectional view of the floor drainage device shown in Figure 1. It is a front view showing the outline of the cleaning board provided in the drainage equipment.

In these figures, 1 is the container body and 2 is the perforated plate. By interposing the joint ring, the perforated plate 2
It can be located above the illustrated position.

3 is a trap action part provided in the vessel body 1;
A riser pipe 4 and a riser pipe 4 connected to a drain pipe
It consists of a bell-shaped body 5 which is inserted into the interior.
The bell-shaped body 5 is provided with wing portions 7 that extend outward and engage with the grooves 6 on the inner circumference of the vessel body 1. The bell-shaped body 5 becomes a non-rotating element due to the engagement of the wing part 7 with the groove 6, and during assembly, the bell-shaped body 5 is dropped into the container body 1 while the wing part 7 is guided by the groove 6. .

8 is a shaft rotatably supported by the perforated plate 2;
is an operating handle connected to this shaft 8 with a pin. The operating handle 9 is always stored in a slot 10 on the perforated plate 2.

11 is a cleaning plate that acts on the bell-shaped body 5 and the riser pipe 4; The cleaning plate 11 is drivingly connected to the shaft 8. This drive connection takes place via an interlock 12 provided at the lower end of the shaft 8. The interlocking part 12 has grooves 13 and 13' into which the cleaning plate 11 enters (see Figure 2).
will be provided.

FIG. 3 shows the working edges 14-17' on the cleaning plate 11.
and the engaging edges 18, 18' are shown. Working edge 14,
14' is for the inner circumferential surface of the riser pipe 4; working edges 15, 15' are for the outer circumferential surface of the riser pipe 4; working edges 16, 16' are for the inner circumferential surface of the bell-shaped body 5; , 17' are for the outer peripheral surface of the bell-shaped body 5. Moreover, the engaging edge 18,
Reference numeral 18' denotes a portion that enters the grooves 13, 13' on the interlocking portion 12, and these engaging edges 18, 18' are formed by providing a recess 20 in the upper center of the cleaning plate.

Cleaning of the trap action section 3 by the cleaning plate 11 is as follows:
Pull the operating handle 9 in the A direction (pin connection point O
This is carried out by manually rotating the operating handle 9 in the state shown in FIG. 4, in which it is tilted and rotated in the B direction.

In order to prevent the operating handle 9 from falling into the slot 10 during cleaning work performed by rotating the operating handle 9, a vertical groove 21 and an annular groove are provided on the shaft 8, as shown in FIGS. 4 and 5. The perforated plate 2 is also provided with a claw 23 that projects from the inner peripheral surface of the boss portion through which the shaft 8 passes. The annular groove 22 receives the pawl 23 so that the shaft 8 can be rotated by the operating handle 9, and when the operating handle 9 is directly above the slot 10 as shown in FIG. This prevents the operating handle 9 from falling into the slot 10.

In order to ensure that the rotation of the cleaning plate 11 by the operation handle 9 proceeds smoothly, the bottom 25 of the container body 1 is
A receiving member 26 having a smooth receiving surface is arranged on top.

Cleaning the shoulder surface 27 of the bell-shaped body 5 has no direct relation to clogging, but is useful for preventing odor caused by rotting foreign matter adhering thereto. In order to clean the shoulder surface 27 in parallel with the cleaning of the trap action section 3, a spacer pipe 28 disposed between the perforated plate 2 and the bell-shaped body 5 is splined to the shaft 8. , the cleaning plate on the shoulder surface 27 is attached to the spacer pipe 28
It may be fixed to the

Effects of the invention: The invention allows belt trap cleaning to be performed as a simple task accompanying floor cleaning work. Therefore, the system according to the present invention not only prevents clogging, but also maintains the initial drainage function for a long time.
