Description

  The present invention relates to a toilet cleaning technique in an automatic flush toilet, and more particularly to a toilet cleaning device that can prevent washing water from flowing carelessly during cleaning of the toilet.

  On the surface of urinals and urinals made of ceramics and the like, scales that cause darkening or urine stones that cause bad odors adhere to the surface of the toilet after long-term use.

  Scale is a siliceous substance contained in tap water and the like, and can be removed relatively easily immediately after adhering. However, if left untreated, it becomes assimilated with the vitreous surface of the toilet bowl and cannot be easily removed.

  On the other hand, urinary stone is a poorly soluble compound that is generated by the decomposition of proteins contained in urine by bacteria. If it adheres to the toilet bowl or its surrounding floor or wall, it cannot be easily removed and disassembled. There is also a problem that the water tube is clogged, and further, because it is porous, it promotes the growth of bacteria and causes a bad environment where dirt is likely to accumulate.

  Therefore, the toilet bowl has been regularly cleaned using an electric rotary brush or the like (for example, Patent Document 1).

Japanese Utility Model Publication No. 61-21394

  However, in an automatic flush toilet where the flush water is automatically supplied into the toilet after the toilet, the cleaning operator is detected or not detected by the sensor unit constituting the automatic flush device during the toilet cleaning operation. There is a disadvantage that the cleaning water is inadvertently supplied into the toilet bowl being cleaned due to irregular repetition.

  Here, if cleaning water is inadvertently supplied into the toilet bowl being cleaned, the cleaning water is wasted and the water-saving effect is reduced, and cleaning detergent and abrasives are washed away during cleaning. As a result, the dirt attached to the toilet cannot be removed well.

  The present invention has been made in view of the above circumstances, and an object thereof is to prevent the washing water from flowing carelessly during cleaning of the toilet in the automatic flush toilet.

In order to achieve the above object, the present invention

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to prevent that wash water will be supplied carelessly during cleaning of a toilet bowl. For this reason, not only the water-saving effect is improved, but also the toilet bowl can be efficiently and satisfactorily cleaned because the detergent and the abrasive are not washed away during the cleaning.

  In addition, according to the present invention, it can be easily installed simply by adsorbing the suction cup to the flat surface in the vicinity of the sensor unit, and it can be easily removed after use without falling off during use.

  In addition, since the sensor cover is connected to the knob portion of the suction cup so as to be displaceable, the sensor cover is moved from the detection position by the sensor section to the non-detection position while the suction cup is adsorbed in the vicinity of the sensor section. Thus, the cleaning water can be supplied to the toilet bowl at the will of the cleaning operator.

  Hereinafter, the present invention will be described in detail with reference to the drawings. First, FIG. 1 shows a configuration example of an automatic flush toilet. In FIG. 1, 1 is a toilet bowl (urinal) to be cleaned, and this toilet bowl 1 is installed with the back surface pressed against the wall surface W of the toilet.

  A drain port 11 is formed at the bottom of the toilet 1, and one end of the drain pipe 2 is connected to the drain port 11. On the other hand, a spout 12 is formed in the upper part of the toilet 1, and one end of the water supply pipe 3 is connected to the spout 12. A water supply valve V is interposed in the water supply pipe 3, and cleaning water is supplied into the toilet bowl 1 by opening thereof, and the cleaning water flows down along the inner surface of the toilet bowl 1.

  C is a control unit that opens and closes the water supply valve V, E is a power supply unit that supplies power to the control unit 5, and S is a non-contact type sensor unit that is conductively connected to the control unit C. It is fixed in the wall surface W above the toilet 1. And based on the object detection by the sensor part S, it is set as the structure which the water supply valve V open | releases for a fixed time at a predetermined timing.

  For example, the sensor unit S includes a retroreflective photoelectric sensor that can detect a toilet user (consumer) standing in front of the toilet 1, and after the user is detected, the user leaves. When the passenger is no longer detected by the sensor unit S, the signal input from the sensor unit S to the control unit C changes (decreases), so that the control unit C determines that the flight is completed and the water supply valve V is turned on. It will be open for a certain time.

  Therefore, according to the automatic flush toilet as described above, even when the toilet 1 is cleaned using a cleaning tool such as a rotating brush, the cleaning operator may or may not be detected by the sensor unit S. By repeating irregularly, the water supply valve V repeatedly opens and closes, and the wash water is inadvertently supplied into the toilet bowl 1.

  Therefore, the present invention uses an instrument 4 as shown in FIG. 2 to prevent the cleaning water from being inadvertently supplied to the inside of the toilet 1 during cleaning. Shield.

  As apparent from FIG. 2, the instrument 4 includes a suction cup 5 and a thin plate sensor cover 6. The suction cup 5 has a suction cup body 51 having an arc-shaped cross section and a knob 52 projecting from the center of the convex surface. The concave surface of the suction cup body 51 opposite to the knob 52 is an arbitrary flat surface. It is assumed that the adsorption surface is capable of adsorbing. The suction cup body 51 has a protrusion (not shown) on the peripheral edge thereof, and the suction cup 5 can be easily separated from the suction surface by pulling the protrusion.

  In the illustrated example, the knob 52 includes a convex portion 52a formed integrally with the suction cup body 51 and a ring 52b attached to the convex portion 52a. A through hole 52c is formed in the convex portion 52a, and a ring 52b is attached to the through hole 52c.

  The ring 52b is made of metal, and the sensor cover 6 is connected to the ring 52b via the flexible connection member 7 so as to be displaceable. The flexible connecting member 7 only needs to have flexibility, and FIG. 2 shows an example in which a leather band is used for this, but as the other flexible connecting member 7, a wire diameter of 0.5 to 2 mm is shown. A metal wire (wire), a metal chain, or a resin string can be suitably used.

  On the other hand, the sensor cover 6 can be moved (moved) 90 degrees or more in the vertical and horizontal directions around the suction cup 5. The sensor cover 6 only needs to have a size that covers the sensor unit S and is detected by the sensor unit S. In this example, the sensor cover 6 is an opaque synthetic resin plate having a length of 90 mm, a width of 70 mm, and a thickness of 1 mm. Is used. In particular, the sensor cover 6 is preferably not transparent. This is because, as the sensor unit S constituting the automatic flush toilet, one that generally cannot detect a transparent body is used. Moreover, since the sensor part S is used for detecting a human body that is basically a non-magnetic material, that is, a user using the toilet 1, the sensor cover 6 detected by this is also a magnetic material. A non-magnetic material may be used. However, in order to prevent the sensor cover 6 from being inadvertently moved to a non-detection position that is not detected by the sensor unit S due to the influence of wind generated by using a rotating brush or the like during cleaning of the toilet bowl 1, It is preferably not a lightweight flexible material such as a resin film but a hard material having a weight of 10 to 100 grams.

  In addition, as shown in FIG. 2, it is preferable that the sensor cover 6 has a note “stop water”, for example. As other precautions, “cleaning” or “use prohibited” may be described. According to this, for example, while the cleaning worker attaches a detergent to the surface of the toilet 1 and leaves the site, the toilet 1 can be used and the detergent or the like can be prevented from being washed away by urine. .

  Next, a toilet cleaning method using the instrument 4 as described above will be described. As shown in FIGS. 3 and 4, before cleaning the toilet 1, first, above the sensor unit S, the sensor unit S The suction cup 5 is attracted to a flat surface (wall surface W) located in the vicinity, and the sensor portion S is covered with a sensor cover 6 connected to the suction cup 5.

  In addition, as shown in FIG. 5, when the sensor unit S has a horizontal plane L, the suction cup 5 is adsorbed on the horizontal plane L. Here, even if there is no flat surface that can adsorb the suction cup 5 directly above the sensor unit S, if the flexible connecting member 7 is a metal wire having a wire diameter of 0.5 to 2 mm, the sensor unit S as shown in FIG. The sensor cover 6 can be held at a detection position by the sensor unit S (a position where the sensor unit S is covered from the front) while the suction cup 5 is adsorbed on a flat surface (wall surface W) positioned beside the side.

  Thus, while maintaining the state in which the sensor unit S is covered with the sensor cover 6, an electric cleaning tool (not shown) in which a buff or a brush is attached to the rotation drive shaft, or a manual cleaning tool such as a brush with a handle is used ( The toilet 1 is polished preferably with a dedicated detergent or abrasive. At this time, since the sensor unit S detects the sensor cover 6 covering the sensor unit S, a cleaning worker who bends or stands up is not detected by the sensor unit S or is not detected. There is no supply of washing water. Thereby, the cleaning operation can be performed smoothly and satisfactorily while washing water is not wasted and the detergent is prevented from being washed away with the washing water.

  Then, after finishing the toilet 1, the sensor cover 6 is pushed up or down with the fingertip, and the sensor cover 6 is detected by the sensor unit S from the detection position by the sensor unit S (the position of the solid line in FIGS. 4 to 7). To the non-detection position (the position of the one-dot chain line in FIGS. 4 to 7) which is not performed, whereby the water supply valve V is opened for a certain period of time by the control unit C shown in FIG. Will be supplied.

  In addition, after washing water is supplied into the toilet bowl 1, if an unpolished portion is found on the surface of the toilet bowl 1, the sensor cover 6 is returned to the detection position by the sensor unit S, and the unpolished portion is polished, and the unpolished portion disappears. The above operations are repeated (usually, it is sufficient to repeat only twice), and when the toilet is completely cleaned, the instrument 4 is removed to complete a series of toilet cleaning operations.

  As described above, the preferred embodiment of the present invention has been described, but in the present invention, the target toilet is not limited to a urinal, and can be applied to a toilet, regardless of whether it is a Western style or a Japanese style. In short, any automatic water-washing type in which washing water is automatically supplied based on object detection by the sensor unit S may be used. Moreover, it is applicable also to the toilet bowl 10 in which the sensor part S was integrated as shown in FIG.
