Description

Detailed Description of the Invention

[0001]

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

[0002]

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

[0003]

However, in the above-mentioned conventional example, the flow of washing water is as shown by the arrow in FIG. 7, and only the range shown by the hatching in FIG. 7 can be washed, and the front wall 5 of the toilet bowl 2 can be washed. There was a problem that the inner surface could not be cleaned. The present invention has been made in view of the above problems, and an object of the present invention is to provide a urinal that can also clean the inner surface of the front wall of the toilet bowl.

[0004]

In order to achieve the above object, the urinal of the present invention is provided with a urinal body 1 having a urinal bowl 2 whose front surface is opened and a cleaning nozzle 3 provided on an upper portion of a back surface 6 of the urinal bowl 2. In the urinal for cleaning the cleaning water discharged from the cleaning nozzle 3 along the back surface 6 and the inner surface of the side wall 7 of the toilet bowl 2, the spout 8 is provided on the inner surface of the front wall 5 of the toilet bowl 2, and the cleaning nozzle 3 It is characterized in that the water discharge port 8 is communicated with a water supply pipe 9 for supplying water to.

After the cleaning water is discharged from the cleaning nozzle 3 and the toilet bowl 2 is subjected to main cleaning, after a predetermined time has elapsed, sub-cleaning for discharging the cleaning water from the spout 8 is performed, and the main cleaning is performed during this predetermined time. It is also preferable to have a control means for controlling so as not to start the sub-cleaning.

[0006]

According to the above construction, in addition to the main cleaning for discharging the cleaning water from the cleaning nozzle 3 to clean the back surface 6 and the inner surface of the side wall 7 of the toilet bowl 2, the water outlet on the inner surface of the front wall 5 of the toilet bowl 2 It is possible to perform sub-cleaning in which washing water is discharged from 8 to wash the inner surface side of the front wall 5, and the inner surface side of the front wall 5 can also be washed and kept clean.

After the cleaning water is discharged from the cleaning nozzle 3 and the toilet bowl 2 is subjected to main cleaning, after a predetermined time has elapsed, sub-cleaning for discharging the cleaning water from the spout 8 is performed, and the main cleaning is performed during this predetermined time. However, if the control means is provided so as not to start the sub-cleaning, the sub-cleaning is not performed each time the main cleaning is performed, but the number of times of the sub-cleaning can be reduced to effectively perform the cleaning and save water.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT As shown in FIGS. 1 and 2, a urinal body 1 is provided with a urinal bowl 2 having a front opening.
A cleaning nozzle 3 for ejecting cleaning water is provided on the upper part of the back surface 6 so as to be horizontally long. A drainage port 4 is provided substantially in the center of the bottom surface 10 of the toilet bowl 2, and a front wall 5 is provided at the lower part of the front surface side of the toilet bowl 2 so as to rise upward, and an inner surface side of the front wall 5 is provided. The water discharge port 8 is provided so as to be horizontally long. A water supply pipe 9 is arranged at the back of the urinal body 1, and the 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 9 a is passed through the back of the urinal body 1, and the main water supply pipe 9 a is connected to the cleaning nozzle 3. The sub water supply pipe 9 is passed through the lower portion of the urinal body 1, and the sub water supply pipe 9 is connected to the water discharge port 8. An on-off valve 11 such as a solenoid valve is arranged in the water supply pipe 9 at a position before a portion where a main water supply pipe 9a and a sub water supply pipe 9b are branched. After the stool,
When the opening / closing valve 11 is opened, the cleaning water is discharged from the cleaning nozzle 3, and the cleaning water flows along the inner surfaces of the rear surface 6 and the side wall 7 as shown by the arrow in FIG. The cleaning water is discharged and the cleaning water is discharged from the front wall 5 as shown by the arrow in FIG.
It flows along the inner surface of the and is sub-cleaned. By the flush water flowing in this manner, the toilet bowl 2 is flushed over a wide range indicated by hatching in FIG.

FIG. 3 shows another practical example. In the case of the present embodiment, the main water supply pipe 9a of the water supply pipe 9 is provided with a first opening / closing valve 11a such as a solenoid valve, and the sub water supply pipe 9b of the water supply pipe 9 is provided with a second opening / closing valve such as a solenoid valve. 11b is provided. A sensor 12 for detecting a human body is provided above the cleaning 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 the person has finished using the toilet and has left, the first opening / closing valve 11a is opened and the cleaning water is discharged from the cleaning nozzle 3 to perform the main cleaning, and a predetermined time t has passed after the main cleaning. The second opening / closing valve 11b is opened and the water discharge port 8
It is controlled so that the cleaning water is spouted from it and is sub-cleaned. Moreover, during the predetermined time t from the main cleaning to the sub cleaning, even if the main cleaning is performed, the signal for starting the sub cleaning is not output. That is, as shown in the time chart of FIG. 4, after a predetermined time t has passed from the main cleaning, the sub-cleaning is performed, and the main cleaning is performed during the predetermined time t before the sub-cleaning. Even if it is done, it does not give a signal to start the secondary cleaning. As a result, the sub-cleaning is not performed each time the main cleaning is performed, the number of times of the sub-cleaning can be reduced, and the sub-cleaning can be effectively performed. The other structure is basically the same as that of the embodiment shown in FIGS.

[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 communicated with the water supply conduit for supplying water to the cleaning nozzle, the cleaning water is discharged from the cleaning 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 possible to perform a secondary cleaning for discharging the cleaning water from the spout of the inner surface of the front wall of the toilet bowl to clean the inner surface side of the front wall. Also, the inner surface of the front wall can be cleaned and kept clean.

According to the second aspect of the present invention, after the cleaning water is discharged from the cleaning nozzle to perform the main cleaning of the toilet bowl, a sub-cleaning is performed in which the cleaning water is spouted from the spout after a lapse of a predetermined time. Since there is a control means for controlling so as not to start the sub-cleaning even if there is a main cleaning within this predetermined time,
Instead of performing sub-washing each time the main washing is performed, the number of times of sub-washing can be reduced to effectively wash and save water.
