Abstract

PURPOSE:To facilitate washing by measuring the distance between a urinal at a men's urinal and a user, and reminding the user of the proper use through detection by means of a water leakage detector in the case of urination going wide of the urinal. CONSTITUTION:A distance measuring means 30 measures the distance between a urinal 10 and a user HM, and its value and the 1st threshold value L1 which is equivalent to the optimum use distance and 2nd threshold value L2 which is larger than the value L1 and which does not act even if the user passes, are compared, and that an approach is made to the urinal when a distance measuring measured value is between L1 and L2, is indicated to an indicating means 50. In addition, a water leakage detecting means 60 is provided on the floor 20 side of the urinal 10, and an indication to remind the user HM of a proper use is made by means of the indicating means 50 through the detection of urine that leaked outside the urinal 10. A auxiliary flushing valve is provided, and a signal is emitted from the water leakage detecting means 60 as occasion arises, and the cleaning of the floor in the vicinity of the urinal 10 is done.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a toilet system for a men's urinal, and particularly to an improvement that allows the user to be informed of usage conditions and to be able to clean the toilet more efficiently.

[Conventional technology]

Traditionally, flush toilet systems for men's urinals have used ultrasonic or optical switches to open and close valves to automate flushing after use. This was done because washing immediately after use increases the efficiency of washing, reduces the generation of strange odors, and requires less water compared to washing at regular intervals. be.

[Invention or problem to be solved]

However, surgical hospitals often perform renal function tests on patients to check their suitability for anesthetics. In this case, if the patient does not urinate properly, the dye used in the test will adhere to the floor, spoiling the aesthetics and adding to the burden of cleaning work. In addition, even in general offices, due to the carelessness of the users, the waste may not be discharged into the toilet bowl and instead flow out onto the floor. On the other hand, in Japanese Patent Application Laid-Open No. 62-211434, ``Device for detecting abnormalities of users in toilets, restrooms, etc.'', a device for detecting abnormalities of users is proposed, or is it aimed at inappropriateness of urination itself? It wasn't something. The present invention has solved these problems, and an object of the present invention is to provide a flush toilet system that facilitates cleaning by reminding the user of the inappropriateness of urinating itself.

[Means to solve the problem]

The present invention, which achieves these objects, is a toilet system used for men's urination, which has the following configuration. That is, a distance measuring means for measuring the distance between the urinal and the user, a first threshold value corresponding to the value measured by the distance measuring means and the optimum usage distance, and the urinal for determining whether it is in the usage state. a comparison means for comparing the second threshold with a larger value than the first threshold; The urinal is characterized by comprising a display means for displaying to the user that the user is approaching the urinal when the signal is received. Further, a means may be provided to measure the parabola drawn by the user's urine and to tell in which direction the parabola should be corrected for proper use. Preferably, if the water comes off the urinal during urination, it is detected by a water leak detector and displayed on the second display means to remind the user to use the water properly. It can also be used in flush toilets.

[Effect]

Each component of the present invention operates as follows. The measuring device is a sensor that determines the usage status of the urinal. The comparison means determines whether the user is using the device at an optimal position where leakage is minimized and the user does not experience psychological discomfort. If the user is not using the device at the optimal location, the display means will alert the user to move.

[Example] The present invention will be explained below using the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, a user HM is standing in front of a urinal 10, and a floor 20 is also provided. A distance measuring means 30 is provided above the urinal 10 at about the height of the user HM's shoulders. The distance measuring means 30 measures the distance between the urinal 10 and the user HM! A method that measures the propagation time of sound waves using an ultrasonic transducer, or a method that optically uses the propagation time or distance difference of light (similar to the Loran method in radio navigation) But that's fine. The comparison means 40 is the measured value of the distance measuring means 30! is compared with the first and second threshold values, for example, a μ processor may be used, or an analog comparator may be used. The first threshold value L1 corresponds to the optimal usage position, and there are two possibilities: near side and far side, but the near side is rarely a problem because the user feels uncomfortable.
Only on the remote side. The second threshold L2 is used to determine whether the box is in use, and is usually a larger value than the threshold L1 of box 1, and is set to a value that does not operate if the user simply passes by. . The display means 50 displays the distance measurement value measured by the comparison means 40! is between the first and second threshold (i.e., t, t</<L
In 2), a display indicating that the user HM is approaching the urinal 10 is displayed, for example, a lamp displaying "Please come closer" is turned on. Distance measurements! If it is within the range of the optimum value L1, there is no need to display anything, or "please use it as is".
etc. may be displayed. In order to prevent the display means 50 from malfunctioning, a dead time corresponding to the travel time of the pedestrian may be provided for the output signal of the comparison means 40, and a plurality of distance measuring means 30 may be provided to take a majority decision. The judgment may be made based on the following. FIG. 2 is an explanatory diagram of the positional relationship between the urinal 10 and the user HM. At the position corresponding to the first threshold L1, the average user will hardly leak outside and will not feel uncomfortable, for example, 30 to 50 CI11, and the usage angle at this time is θ1. Become. At the position corresponding to the second threshold L2, the distance is such that it would be difficult for an average user to urinate inside the urinal 10, for example, 100 cl. The angle of use at this time is θ2. The operation of the device configured in this manner will be described next. Distance measurements! If is within the range of the optimum value L1, urine will not leak out of the urinal 10 without any special instruction, and therefore the display means 50 does not need to operate in principle. Distance measurement value with comparison means 40! If the value is between the first and second thresholds, there is a risk of urine leaking out of the urinal 10.
The user HM is alerted via the display means 50. If the user HM follows this precaution, there will be less dirt. FIG. 3 is a block diagram of a first modified embodiment of the present invention. In FIG. 3, parts having the same functions as those in FIG. In the figure,
The water leak detection means 60 is a water drop sensor provided on the floor 20@ of the urinal 10, and detects urine leaking to the outside of the urinal 10. The display means 70 is attached to the display means 50, and when a water leak is detected by the water leak detection means 60, it urges the user HM to use the water properly, and displays, for example, a message such as rPlease use it correctly. do. In this case, in order to distinguish between pressure and cleaning water, it is preferable to attach a temperature sensor and send a signal to the display means 70 if the temperature is, for example, 30 degrees Celsius or higher. This eliminates the need for unnecessary display operations. In addition, an auxiliary flush valve 80 is installed to flush the floor 2 near the urinal 10.
0, water leakage detection means 6
It is best to send a signal from 0 and clean it immediately. This allows for reliable cleaning. FIG. 4 is a block diagram of a second modified embodiment of the present invention. Basically, the device shown in FIG. 1 is applied to a flush toilet system. The comparison means 90 compares the second threshold L2 and the measured distance value! Compare the distance measurements! It has a timer that starts counting when the value is less than this threshold. This timer has a dead time of, for example, 2 seconds, which is sufficient to avoid a situation in which the distance measuring means 30 misidentifies a passing person as the user HM. And the distance measurement value after the timer exceeds this dead time!
When becomes larger than the second threshold L2, it is assumed that the use has ended and a valve operation signal is sent. The flushing pulp 100 receives a valve operation signal from the comparing means 90 and supplies a predetermined amount of cleaning material such as water or foam to the urinal 10. In this way, even in the flush toilet system, there is less dirt in areas other than the urinal 10, and cleaning work becomes easier. FIG. 5 is a block diagram of a third modified embodiment of the present invention. Compared to FIG. 1, the displayed content is more detailed and the user HM is informed of what to do. The detection means 110 is a sensor that measures the shape of a parabola drawn by the urine of the user HM, and may directly obtain information on the entire parabola using a three-dimensional porogram, or may measure the positions of three or more points on the urine. You can also measure and determine the parabola. In this case, the urine velocity may be determined using, for example, the Doppler effect. The trajectory calculation means 120 calculates parameters that determine the shape of the urine from the measured values measured by the detection means 110. The teaching means 130 handles the pre-stored urinal 10 and the parabola calculated by the trajectory calculation means 120 in the same coordinate system, and determines the position on the urinal 10 that the parabola reaches. If the position is a position where there is no risk of urine etc. being scattered outside, that fact is memorized. In addition, if the position is a position where there is a risk of urine etc. scattering outside, or if the position is not toward the inside of the urinal 10, the correction direction of the parabola or the user's movement direction to reach the position where no leakage occurs is calculated. do. The display means 140 receives the signal from the teaching means 130, and when displaying the position, displays which direction the user should move toward the urinal 10, front, back, left, or right, centering on the user HM. . If the direction is displayed,
Displays whether to raise or lower the elevation angle. If it is acceptable as is, display the current state or display nothing at all. With a device configured in this manner, it is easy for the user to understand how to modify the HM to operate the device, so that legitimate use can be expected more reliably.

【Effect of the invention】

As explained above, according to the present invention, since the user HM is informed whether the urinal is in the correct state of use using the display means, dirt on the urinal 10 is reduced and cleaning work is facilitated. Moreover, if it is used in combination with the water leak detection means 6o as in the embodiment, even if it gets dirty by mistake, it can be cleaned immediately.
