Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a flush toilet in which the inside of a bowl of a toilet bowl is washed with supplied wash water.

(Prior Art) For example, a flush toilet in which flush water is supplied by operating a flush valve or the like to wash a toilet after use of the toilet is well known.

In such a flush toilet, the flush water is supplied according to the operation of the flush valve, and the amount of the flush water supplied is substantially constant for each flush valve operation.

(Problems to be solved by the invention) Therefore, in such a conventional flush toilet, if the drain pipe is clogged with, for example, dirt, or if it is clogged, the flush valve is operated to maintain a substantially constant amount. Since the cleaning water is supplied, the cleaning water may overflow from the balls depending on the supply amount.

Then, the wash water overflowing from the balls flows not only to the floor of the toilet but also to the outside of the toilet room in a severe case, which causes a great inconvenience to people on the floor and users of the toilet.

Therefore, the present invention has been made to solve such a problem.The purpose of the present invention is to stop the supply of washing water when the drain pipe is clogged and prevent the toilet from being used thereafter. By doing so, it is possible to provide a flush toilet in which flush water does not overflow and does not bother the user.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a flush toilet in which flush water is supplied to clean the inside of the bowl 1a of the toilet bowl 1, and the water level in the ball 1a is a predetermined value. Water level detection means 10 and 19 for detecting the above cases and this water level detection means 10 and 19
Is provided with a wash water supply stop means 9 for stopping the supply of the wash water when the water level in the ball 1a becomes a predetermined value or more based on the output signal of the water level detection means 10 and 19. Based on this, display means 15 is provided for displaying that the flush toilet is in an unusable state when the water level in the ball 1a exceeds a predetermined value.

(Operation) According to such a configuration, when the water level in the ball becomes equal to or higher than the predetermined water level due to the output signal of the water level detection means, the supply of wash water is stopped by the wash water supply stopping means,
The water level in the ball will not rise any further, and therefore the wash water will not overflow from the ball.

In addition, the display means makes it possible for no one to use the toilet thereafter, and to promptly notify the manager or the like that the drain pipe is clogged.

(Embodiment) An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a flush toilet, FIG. 2 is a perspective view showing a toilet bowl, FIG. 3 is a partial sectional side view showing a rear portion of the toilet bowl, and FIGS. 4 and 5 are views showing another embodiment. Is.

In the figure, 1 is a toilet bowl, 2 is a pipe support box, 3 is a water supply pipe, 4 is a drain pipe, 5 is a booth for partitioning the toilet bowl 1, and 6 is a door.

A branch water supply pipe 3a for supplying flush water to the toilet bowl 1 is provided between the water supply pipe 3 and the toilet bowl 1. The branch water pipe 3a is provided with flush water for the toilet bowl according to the operation of the toilet user. There is provided a flash valve 7 for supplying water and a solenoid valve 9 which is a cleaning water supply stopping means of the present invention which is driven by a control unit 8 described later and closes the branch water supply pipe 3a.

On the other hand, at the rear end of the upper end of the bowl 1a of the toilet bowl 1, the toilet seat 1b
A float switch 10 as a water level detecting means of the present invention is provided so as to be covered with the water.

This float switch 10 is, as is clear from FIG.
Float 11, arm 12 swingably supporting this float 11 at one end, and arm 12 accompanying the upward movement of this float 11.
Limit switch 1 opened and closed by swinging the other end 12a
3, and a protective cover 14 covering them,
The limit switch 13 is connected to the control section 8 provided at an appropriate place.

Further, in the vicinity of the door 6 of the booth 5, there is provided a display means 15 constituted by a liquid crystal panel for displaying whether or not the toilet is in a usable state based on a command from the control section 8.

The operation of the present embodiment based on the above configuration will be described below.
For example, when the flush valve 7 is operated when the drain pipe 4 or the branch drain pipe 4a connecting the drain pipe 4 and the toilet bowl is clogged with dirt or the like, the water level in the toilet bowl 1a rises due to the supplied cleaning water. When the water level reaches or exceeds the position of the float 11, the limit switch 13 is closed. The closing of the switch 13 is transmitted to the control section 8 as a water level detection signal indicating that the water level in the ball has reached a predetermined value or more, and the control section 8 operates the solenoid valve drive circuit by the water level detection signal. While closing the solenoid valve 9 by operating the display means drive circuit, the display means 15 is caused to display that the toilet is in an unusable state.

Thus, the subsequent supply of washing water is immediately stopped by the solenoid valve 9, so that the rise of the water level in the bowl is stopped and the washing water can be prevented from overflowing from the bowl of the toilet bowl. Further, the display of the display means 15 eliminates the use of the toilet, so that the user after that does not cause any inconvenience, and the manager etc. is informed immediately that the drain pipe of the toilet is clogged. Can be tightened.

Although one embodiment of the present invention has been described above, the present invention is not limited to such an embodiment. For example, the float switch 10 as the water level detecting means is the swing arm type shown in FIG. Instead, as shown in Fig. 4, the water entrance
A ball-shaped float 17 that moves up and down in accordance with the vertical movement of the water level is provided in the tubular body 16 provided with 16a and the air bleeding hole 16b, and the limit provided at the upper end of the tubular body 16 by the upward movement of the float 17. The switch 18 may be closed, and further, instead of these float switches, a reflected light detection type optical sensor 19 is arranged toward the lower side of the toilet as shown in FIG. It can also be configured by allowing the light receiving element 19b to detect the reflected light only after the irradiated light is reflected by the water surface in the ball that has reached a predetermined water level.

Further, in this embodiment, the flush valve is taken as an example of the washing water supply operation section and the electromagnetic valve is shown as an example of the washing water supply stopping means, but the present invention is not limited to these.

(Effect of the Invention) As is clear from the above description, according to the flush toilet according to the present invention, the flush water supply is stopped when the water level in the bowl of the toilet bowl reaches or exceeds the predetermined water level. The water level inside will not rise any further, so that even if the drain pipe becomes blocked, the wash water will not overflow from the bowl.

Further, after such a state, there is no one who uses the toilet by the display means, so that the user is not inconvenienced, and further the administrator can be informed of the state immediately. .
