Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning device for a toilet bowl, a bidet, etc., which cleans the area to be cleaned by a user after using the toilet.

FIG. 1 shows the configuration of a conventional cleaning device, in which 1 is a toilet main body, 2 is a cistern that stores water for washing the inside of the toilet main body 1, 3 is a toilet seat,
4 is the user sitting on the toilet seat 3; 5 is the user 4
a cleaning nozzle for discharging cleaning water to the part to be cleaned; 6 is the cleaning water being discharged; 7 is a water supply means; this water supply means 7 sucks water from the cistern 2 and supplies water to the cleaning nozzle 5; It has a built-in pump, controller (none of which are shown), etc.

In the conventional configuration shown in FIG. 1 above, when the user energizes the water supply means 7 after using the toilet, the washing water 6 is discharged from the washing nozzle 5, and the part to be washed of the user 4 is washed. However, the position of the part to be cleaned of the user 4 shifts depending on how the user 4 sits, so the position is usually not fixed. Therefore, the cleaning water 6 often comes off the part to be cleaned by the user 4 and wets the surrounding area, and as a result, it wets unnecessary parts, causing discomfort to the user and also cleaning a wide area. This has the disadvantage that it takes time to wipe off the wet area and dry it after cleaning.

Further, even if it is found that the washing water has come off the part to be washed, the surface of the toilet seat 3 is configured so that the user's buttocks spread when sitting.
It is difficult for the user to move his or her buttocks in order to apply the dislodged cleaning water to the area to be cleaned, and this is extremely inconvenient.

In view of the above conventional drawbacks, the present invention provides a position detecting means for detecting the position of a user's part to be cleaned, and a cleaning device that drives the cleaning nozzle to discharge cleaning water to the position of the user's part to be cleaned. and a nozzle driving means, and the position of the cleaning nozzle is determined by the cleaning nozzle driving means so that the cleaning water is discharged to the part to be cleaned of the user confirmed by the position detection means. After that, the above-mentioned drawbacks of the conventional method are solved by supplying water from the water supply means and discharging the washing water.

Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. FIG. 2 shows a functional block diagram of a cleaning device in one embodiment of the present invention.
Parts that are the same as those in the drawings will be described using the same numbers. In this FIG. 2, 8 is a position detection means for detecting the position of the part to be cleaned by the user, 9 is an infrared sensor for detecting the temperature near the part to be cleaned by the user, and 10 is the infrared sensor 9 for detecting the position of the part to be cleaned by the user. 11 is an amplifier that amplifies the signal from the infrared sensor 9; 12 is a filter that cuts noise from the output of the amplifier 11; 13 is the filter 12; A discriminator 14 for discriminating the magnitude of the output from the amplifier 11 via the discriminator 13 is a memory that stores (chronologically) the results discriminated by the discriminator 13 in correspondence with the scan. to 14 constitute the position detection means 8. Reference numeral 15 denotes a cleaning nozzle driving means that retrieves the value in the memory 14 when the scanning is completed, and drives and positions the cleaning nozzle 5 so that the cleaning water is discharged to the position with the highest temperature. . The scanner 10 generally uses an optical system, and the cleaning nozzle driving means 15 is given, for example, the amount of movement in X and Y as digital values, and positioning is performed using a stepping motor according to the values. Uses an XY direction driver.

In the above configuration, when the user presses a cleaning switch (not shown) after finishing using the toilet, the infrared sensor 9 and the scanner 10 scan the temperature near the user's area to be cleaned. The temperature at each point according to this scan is determined by the amplifier 11 and the filter 1.
2. Stored in the memory 14 via the discriminator 13. The time required for scanning is instantaneous. When the scan is completed, the cleaning nozzle driving means 15 drives and fixes the cleaning nozzle 5 so that the cleaning water is discharged to the position in the memory 14 exhibiting the highest temperature. When the water supply means 7 is energized when the cleaning nozzle 5 is fixed, the cleaning water 6 is discharged from the cleaning nozzle 5. Since the temperature of the anal region is higher than that of the surrounding non-mucosal region, the above-described operation ensures that the cleaning water is discharged to the user's region to be cleaned (anal region). Therefore, the user's area to be cleaned can be efficiently cleaned without being affected by the shape of the toilet bowl or seat, the size of the user's body, the sitting posture, etc.

It goes without saying that the present invention can also be applied to bidets for women.

As is clear from the above description, the cleaning device of the present invention includes a water supply means, a cleaning nozzle that discharges cleaning water to the user's part to be cleaned by water supply from the water supply means, and a cleaning device to be cleaned by the user. and a cleaning nozzle drive means for driving the cleaning nozzle to discharge cleaning water to the position of the part to be cleaned of the user, The cleaning nozzle is driven by the cleaning nozzle drive means so that the cleaning water is discharged to the location of the user's part to be cleaned, and after the cleaning nozzle is fixed, the water supply means is energized to supply the cleaning water. Since the cleaning water is discharged onto the user's part to be cleaned, it is ensured that the cleaning water is discharged onto the user's part to be cleaned.Therefore, unlike conventional methods, the cleaning water does not hit the user's part to be cleaned and wastefully wets the surrounding area. This may cause discomfort to the user, or it may cause the user to get a wide area wet, resulting in wasted time wiping off water and drying after washing, or forcing the user to move the buttocks. In addition, the washing water can be applied to the user's area without being affected by the shape of the toilet bowl or seat, the size of the user's body, or the sitting posture, making it highly versatile. It is possible to perform rich and efficient cleaning. Furthermore, the conventional mental burden of worrying about whether or not the cleaning water will hit the user's area to be cleaned can be eliminated.

Note that the position detection means may be an infrared sensor,
A scanner that scans this infrared sensor,
It is composed of an amplifier that amplifies the signal of the infrared sensor, a discriminator that discriminates the magnitude of the output of the amplifier, and a memory that stores the output of this discriminator. By determining that it is a cleaning part, the user's part to be cleaned can be detected quickly and reliably.
