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, etc.

BACKGROUND OF THE INVENTION: Floor drainage devices known as belt traps are widely used to drain water from floors, but they tend to clog and require tedious disassembly to clear them. The floor drainage equipment developed by the applicant to improve this point was developed in the 1980s.
−14856 Publication, Jitsukō No. 60-14857, Jitsukōaki
It is shown in Japanese Utility Model Publication No. 60-14858 and Japanese Utility Model Publication No. 60-19188 together with a conventional belt trap. Figures 4 to 7
The figures are selected from these publications and the numbers have been changed. Figure 4 shows the belt trap BT, and Figures 5 to 7 show the floor drainage equipment with improved flow path configuration.
Show IT ₁ IT ₂ .

A floor drainage device with an improved flow path configuration is provided with a drainage inlet path, a drainage path forming a trap, and a water sealing partition weir between them directly below the perforated plate.
It can be said that the ceiling wall of the discharge passage is of the type provided by the inclined wall on the introduction passage.

Regarding this temporary device, the device CL (No. 7
(see figure) is proposed.

Problems to be solved by the invention: In order to clean the area S using the instrument CL shown in Fig. 7, a slot is provided in the perforated plate M into which the scraping action part of the instrument CL enters. It is difficult to make all the cleaners understand the purpose of this slot, and there are also problems with storing the instrument, so the instrument CL is rarely used.

Means for solving the problem: In the above-mentioned type, the present invention is such that the scraper for cleaning the inclined wall on the drainage channel facing the perforated plate is rotatably supported by the center of the perforated plate. In addition to providing an operating handle that is drive-coupled to the boss portion for vertical movement, a radial slot is provided to allow the operating handle to be dropped in the rotational phase in which the cleaning scraper is inactive. It is characterized by being provided on the top.

Operation: A radial slot on the perforated plate acts in conjunction with the operating handle as a locking device to keep the cleaning scraper in the inactive position. Although the cleaning scraper may be operated at any time, it is desirable to operate it in parallel with the finishing water application when floor cleaning is substantially complete.

Embodiment: Figure 1 is a vertical cross-sectional view of the floor drainage device according to the present invention. With interposed water sealing partition weirs, they are trap 4
form. Reference numeral 5 denotes a sloped wall on the introduction path 1, and this sloped wall 5 serves as a ceiling wall of the discharge path 2.

The inclined wall 5 has to be provided at the upper part of the introduction channel 1 in order to form a trap 4 with low flow resistance, and provides a place where foreign matter is likely to adhere and accumulate. Reference numeral 6 denotes a cleaning scraper (hereinafter simply referred to as scraper) provided to this inclined wall 5.
The boss portion 7 is rotatably supported by the center of the perforated plate 8. Reference numeral 9 denotes an operation handle of the scraper 6, which is driven and connected to the boss portion 7 of the scraper 6 so as to be vertically movable. In order to keep the operating handle 9 permanently retracted, a radial slot 10 is provided in the perforated plate 8 at a location where the scraper 6 is placed away from the inclined wall 5 and inactive, as shown in FIG. That is, the slot 10 and the operating handle 9 act as a locking device that keeps the scraper 6 in the non-operating position at all times.

Cleaning of the inclined wall 5 is carried out by picking up the operating handle 9 from the slot 10 and then rotating the operating handle 9 a few times as shown in FIG. Can the scraper 6 be made of any material?
It is desirable that the scraping action part be made of rubber and the boss part made of metal.

FIG. 3 shows the operating state in which the scraper 6 is rotated by 180 DEG from the state shown in FIG.

The operating handle 9 can be used by being pulled out from the slot 10 on the perforated plate and then rotated by 180° in a vertical plane. Furthermore, the lifting projection provided on the operating handle can be provided as an element that can be tilted horizontally in order to avoid protrusion from the floor surface.

Effect of the invention: The present invention has the operation handle 9 to inform the cleaner that the floor drainage equipment should be cleaned at the same time as cleaning the floor, thereby preventing the floor drainage equipment from emitting abnormal odors. This has the effect of preventing problems from occurring.

[Brief explanation of the drawing]

FIG. 1 is a vertical sectional view illustrating a drainage device according to the present invention, FIGS. 2 and 3 are explanatory views showing the scraper in the device shown in FIG. 1 in different states,
FIG. 4 to FIG. 7 are diagrams for explaining the conventional technology,
FIG. 4 shows a belt trap, and FIGS. 5 to 7 show a floor drainage device with an improved flow path configuration that avoids the disadvantages of the belt trap.
