  • Sanitary Device For Flush Toilet (AREA)

Abstract

PURPOSE:To prevent the occurrence of seal-break in a trap caused by the evaporation of water and flush cleaning water effectively. CONSTITUTION:A water level detection sensor 15 is provided so as to detect a water level in a trap 12 installed to the lower part of a bowl surface where there is provided a control box 19 which on/off controls a water supply valve 6 based on the output transmitted from the detection sensor 15. When the water collected in the trap 12 is evaporated and results in a drop in the water level, the water supply valve 6 is opened in response to the output from the water level detection sensor 15. Then, cleaning water flows out from a cleaning nozzle to supply water into the trap 12, thereby protecting the trap 12 from seal- breaking produced by the evaporation of water. The opening of the water supply valve 6 based on the water level detection sensor does not take place except when the water level L in the trap 12 is lowered. This construction makes it possible to eliminate useless supply of cleaning water.

Embodiments of the present invention will be described below with reference to the drawings. Front part 1a of the urinal body 1 used in this embodiment
2, a bowl surface 2 surrounded by an annular rim 3 is provided, a horizontally long slit-shaped cleaning nozzle 4 is provided in the upper center of the bowl surface 2, and above the cleaning nozzle 4. Is provided with a human body detection sensor 5 for detecting a human body. The washing nozzle 4 is, as shown in FIG. 1, a water supply valve (solenoid valve) disposed on the back surface 1b of the urinal body 1.
6 is connected to the connection pipe 7 on the secondary side, and the connection pipe 8 on the primary side of the water supply valve 6 is connected to the water supply pipe 10 via the water stopcock 9. By opening the water supply valve 6, the water supply pipe 10 is disconnected from the water supply pipe 10. The cleaning water is supplied to the cleaning nozzle 4. On the other hand, in the lower part of the bowl surface 2, as shown in FIG. 3, a trap section 12 on which a trap plate 11 is detachably mounted is provided. A discharge pipe 14 is provided in the bottom portion 13 of the trap portion 12 so as to penetrate therethrough in the vertical direction.
The upper end 14a of the above protrudes above the bottom portion 13. As a result, the water level L in the trap portion 12 is normally the drain pipe 1
4 is located at the upper end 14a. Further, the lower end 14b of the discharge pipe 14 projects downward from the bottom of the trap portion 12 and is connected to a drain pipe (not shown). Further, a water level detection sensor 15 is provided in the trap section 12. The water level detection sensor 15 plays a role of outputting a detection signal to the control box 19 via the lead wire 16 when the water level L in the trap section 12 becomes lower than a certain level.

As shown in FIG. 1, the control box 19 is arranged on the side of the water supply valve 6 and has a structure which also serves as a battery box, for example. The control box 19 is connected to the water level detection sensor 15 via a lead wire 16 and individually connected to the human body detection sensor 5 and the water supply valve 6 via other lead wires 17 and 18. Accordingly, when the water level detection sensor 15 detects a decrease in the water level L in the trap portion 12 or when the human body detection sensor 5 detects the presence of a human body, those detection signals are individually transmitted to the control box 19. . The control box 19 has a built-in control circuit (not shown) for opening the water supply valve 6 in response to the output from the water level detection sensor 15 or the human body detection sensor 5.

Here, when the water stored in the trap portion 12 evaporates and the water level L drops below a certain level, the control box 19 controls the water supply valve 6 in response to the output from the water level detection sensor 15. Open. As a result, the water supply pipe 1
The cleaning water in 0 is supplied to the cleaning nozzle 4 via the connecting pipes 7 and 8, and the cleaning water flowing out from the cleaning nozzle 4 is used as the bowl surface 2
Since it is poured into the trap section 12 after cleaning
The water level L in the trap section 12 is returned to the original level.
Therefore, it is possible to effectively replenish the trap portion 12 with water without setting the time for intermittently flowing the wash water as in the conventional case, and prevent the trap portion 12 from being ruptured due to water evaporation. . Moreover, the water supply valve 6 by the water level detection sensor 15
Is not opened except when the water level L in the trap section 12 is lowered, so compared with the conventional intermittent water supply system,
There is an advantage that wasteful supply of washing water can be eliminated.

As described above, the present invention includes the cleaning nozzle provided on the upper portion of the bowl surface and the water supply valve which is opened and closed to supply the cleaning water to the cleaning nozzle, and is provided on the lower portion of the bowl surface. The water level in the trap part is detected by the water level detection sensor, and the water supply valve is opened / closed based on the output from the water level detection sensor. It is possible to prevent the seal from being broken by supplying water to the trap portion by the cleaning water supplied from the cleaning nozzle without setting such a time. Moreover, since the water supply valve is not opened by the water level detection sensor except when the water level in the trap is lowered, it is more efficient and efficient than the conventional intermittent supply of cleaning water at regular intervals. Can be flushed. Such an advantage is also effective, for example, when the water level in the trap portion suddenly drops due to pressure fluctuations in the toilet room and the drain pipe.
