DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for cleaning a toilet bowl in a urinal.

[0002]

2. Description of the Related Art As shown in FIGS. 4 and 5 , a conventional urinal is provided with a urinal bowl 2 having a front surface opened in a urinal body 1, and a cleaning nozzle for discharging cleaning water at an upper portion of a rear surface 6 of the urinal bowl 2. 3 are formed. A drain port 4 is provided on the bottom surface of the toilet bowl 2, and a front wall 5 is provided at a lower portion on the front side of the toilet bowl 2 so as to stand up. In such a conventional example, when the washing water is discharged from the washing nozzle 3 after the stool, the washing water flows as shown by an arrow in FIG.
The rear surface 6 and a part of the inner surface of the side wall 7 are cleaned.

[0003]

However [0007], in the above prior art the flow of the washing water becomes as indicated by the arrows in FIG. 6, FIG.
6 , only the area indicated by hatching can be washed, and there is a problem that the inner surface of the front wall 5 of the toilet bowl 2 cannot be washed. The present invention has been made in view of the above problems, and an object of the present invention is to provide a urinal capable of cleaning the inner surface of the front wall of a toilet bowl.

[0004]

In order to achieve the above object, the urinal of the present invention comprises a urinal body 1 having a toilet bowl 2 having a front opening and a washing nozzle 3 provided above a rear surface 6 of the toilet bowl 2. In the urinal for flushing flush water discharged from the flush nozzle 3 along the back surface 6 and the inner surface of the side wall 7 of the toilet bowl 2, a spout 8 is provided on the inner surface of the front wall 5 of the toilet bowl 2. The water outlet 8 communicates with a water supply pipe 9 for supplying water to the washing nozzle 3, and the washing water is discharged from the washing nozzle 3 to
After a predetermined time has passed after the main bowl 2 has been washed,
Sub-washing to discharge the washing water from the
Control that does not start sub-cleaning even if there is cleaning
It is characterized by having means .

[0005]

[0006]

According to the above construction, in addition to the main washing for discharging the washing water from the washing nozzle 3 to wash the inner surfaces of the back surface 6 and the side wall 7 of the toilet bowl 2, a spout port on the inner surface of the front wall 5 of the toilet bowl 2. Sub-cleaning for cleaning the inner surface side of the front wall 5 can be performed by discharging the cleaning water from 8, and the inner surface side of the front wall 5 can also be cleaned and kept clean.

After the washing water is discharged from the washing nozzle 3 and the toilet bowl 2 is mainly washed, after a lapse of a predetermined time, a sub-washing operation of discharging the washing water from the water discharge port 8 is performed. If control means for controlling the sub-washing so as not to be started is provided, the sub-washing is not performed every time the main cleaning is performed, but the number of the sub-washings can be reduced to effectively perform the cleaning, thereby saving water.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, a urinal body 1 is provided with a toilet bowl 2 having a front opening.
A cleaning nozzle 3 for discharging cleaning water is provided on an upper portion of a back surface 6 of the printer so as to be longer in a lateral direction. A drain port 4 is provided substantially at the center of the bottom surface 10 of the toilet bowl 2, and a front wall 5 is provided at the lower part on the front side of the toilet bowl 2 so as to rise upward. Is provided so that the water discharge port 8 becomes long horizontally. A water supply pipe 9 is arranged at the back of the urinal body 1, and this water supply pipe 9 is branched into a main water supply pipe 9a and a sub water supply pipe 9b. The main water supply pipe 9a passes through the back of the urinal main body 1, and the main water supply pipe 9a is connected to the washing nozzle 3. The auxiliary water supply pipe 9 passes through the lower part of the urinal main body 1, and is connected to the water outlet 8. An opening / closing valve 11 such as a solenoid valve is disposed in the water supply pipe 9 at a position before a portion branched into a main water supply pipe 9a and a sub water supply pipe 9b. Then, after stool,
When the on-off valve 11 is opened, the washing water is discharged from the washing nozzle 3 and the washing water flows along the inner surface of the back surface 6 or the side wall 7 as shown by the arrow in FIG. The cleaning water is discharged, and the cleaning water is supplied to the front wall 5 as shown by the arrow in FIG.
Flows along the inner surface of the substrate and is sub-cleaned. The toilet bowl 2 is washed over a wide range as shown by hatching in FIG.

In the case of the present invention, a first opening / closing valve 11a such as an electromagnetic valve is provided on the main water supply pipe 9a of the water supply line 9 and a second opening / closing valve 9b such as an electromagnetic valve is provided on the sub water supply pipe 9b of the water supply line 9. Two on-off valves 11b are provided. A sensor 12 for detecting a human body is provided above the washing nozzle 3, and the control circuit of the control box 13 controls the first opening / closing valve 11a and the second opening / closing valve 11b based on the detection of the sensor 12. It has become. When the sensor 12 detects that a person has left after finishing the stool, the first opening / closing valve 11a is opened and the washing water is discharged from the washing nozzle 3 to perform the main washing, and a predetermined time t after the main washing is performed. When the time has elapsed, the second on-off valve 11b is opened, and control is performed so that the washing water is spouted from the spout 8 to perform sub-washing. In addition, for a predetermined time t from the time of performing the main cleaning to the time of performing the sub-cleaning, control is performed so that a signal for starting the sub-cleaning is not output even if the main cleaning is performed. That is, as shown in the time chart of FIG. 3, the sub-cleaning is performed after a lapse of a predetermined time t from the main cleaning, and the main cleaning is performed for a predetermined time t until the sub-cleaning is performed. Even if it is performed, a signal for starting the sub-cleaning is not issued.
Thus instead of the sub-cleaning is performed every time the main wash, it can be determined promptly by using an effective sub-cleaning it is possible to reduce the number of sub-cleaning.

[0010]

As described above, according to the present invention, since the water outlet is provided on the inner surface of the front wall of the toilet bowl and the water outlet is connected to the water supply pipe for supplying water to the washing nozzle, the washing water is discharged from the washing nozzle. In addition to the main cleaning for cleaning the back surface and the inner surface of the side wall of the toilet bowl, it is also possible to perform a sub-cleaning in which the cleaning water is discharged from the water discharge port on the inner surface of the front wall of the toilet bowl to wash the inner surface side of the front wall. The inside of the front wall can be cleaned and kept clean.

[0011] Also, after the main wash the toilet bowl by discharging washing water from the washing nozzle, there is a main cleaning in sub washed performed and the predetermined time for spouting flush water from the predetermined time has elapsed after the water discharge port Also has control means to control not to start the sub-cleaning, instead of performing sub-cleaning every time the main cleaning is performed,
The cleaning can be effectively performed by reducing the number of times of sub-cleaning, and water can be saved.
