## Title
Coin operating bidet response to user's selection

## Abstract

A user controlling coin operating bidet assembly is comprised of a coin handling system with a coin collector box and an electrically operating bidet. The coin handling system contains optical coin validator, solenoid valves, coin flaps, optical coin counter, electronic timer, and microprocessor controlling those parts according to the signals triggered by the coins inserted. The electronic timer receives signal from the microprocessor and supplies power to another solenoid valve and a warm air blower connected to the bidet. A switch for selecting water and air is attached on the control panel of the bidet. 25 cents coin allows 30 seconds operation. Additional 25 cents inserted within 30 seconds extends the operation time for another 30 seconds. Emergency “HOLD” switch placed on the control panel holds the power to the bidet and stops the electric timer. Pressing “RESET” switch on the control board returns the bidet in a continuing mode.

## Background
FIELD OF THE INVENTION
Current application related with a bidet, especially, a bidet operated by coin and the method of assembling the coin handling system and the bidet to respond to user's choice.
BACKGROUND OF THE INVENTION
Bidet is more popular in Europe and Japan rather than in the United States because every house in the United States has showering system built therein. However, many immigrants to the United States from those countries brings bidet and custom of using it with them and spreads it throughout their communities because it is more convenient than taking a shower. Conventional bidet is produced for private use in a house. In spite of the huge numbers of public toilets on the street, there is no public bidet even in the Hotels. In these days, more people prefers bidet if they try it once because it is more clean and make them feel pleasant. Especially, ladies favor bidet because it is known to be good for their sanitary hygiene. Many ladies wait for public rest rooms equipped with bidets. For many paid public restrooms, it is useless when more than one-person get in the restroom with one token. Attaching coin collector to each toilet commode has no meaning at all. But, for bidet, it is very effective to control the use of it.
It is the purpose of the current application to provide a bidet system, which is installable in public restrooms and makes money for maintaining the bidet system. Another purpose of the current application is to improve the function of bidet responding to user's selection.

SUMMARY OF THE INVENTION
Conventional bidet is produced for private use in a house. In spite of the huge numbers of public toilets on the street, there is no public bidet even in the Hotels. In these days, more people prefer bidet if they try it once because it is more clean and make the them feel pleasant. Especially, ladies favor bidet because it is known to be good for their generic hygiene. Many ladies wait for public restrooms equipped with bidets. For many paid public restrooms, it is not economical to install coin pay system when more than one person get in the restroom with one token. Attaching coin collector to each toilet commode has no meaning at all because people can use it without flushing water. But, for bidet, it is very effective because user must pay for the water to wash their body. It is the purpose of the current application to provide a bidet system, which is installable in public restrooms and makes money for maintaining the bidet system. A coin-operating bidet for the purpose of the current application is comprised of a coin handling system with a coin collector box and an electrically operating bidet. The coin handling system contains a coin validator, solenoid valves, coin flaps, coin counter, electronic timer, and micro-processor controlling those parts according to the signals triggered by the coins inserted. The electronic timer receives signal from the microprocessor and supplies power to another solenoid valve and a warm air blower connected to the bidet. A switch for selecting water and air is placed on the control panel of the bidet. 25 cents coin allows 30 seconds operation. Additional 25 cents inserted within 30 seconds extends the operation time for another 30 seconds. Emergency “HOLD” switch placed on the control panel holds the power to the bidet and stops the electric timer. Pressing “RESET” switch on the control board returns the bidet in a continuing mode.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG. 1 is a perspective view of a coin-operating bidet (1) of the current application. The bidet (1) according to current application is a mountable bidet to any of existing commode seat in public rest rooms. Therefore, a seat lid (2) and a seat cover (3) are assembled to a control box (4) and a coin handling system (5) via line covers (6), which covers electric-wires connected to solenoid valves (not show in the figures) that control the stream of water and air through a nozzle (7).
FIG. 2 is a schematic logic diagram of the coin bidet (1) of the current application. The logic diagram is easily understood by referring FIG. 2 to FIG. 4. When a coin (8) is inserted to the coin handling system (8-1) through an inserting slot (9), the coin (8) passes through a coin validator (10). In the coin validator (10), the coin is detected by optical and/or magnetic readers as known in the prior art. The information read by the validator (10) is sent to a microprocessor (11) and compare with information of validated coins. If the coin (8) inserted is not validated, a signal to turn the coin flap (12) to a position of open to return slot (13) is sent to a solenoid valve (14) that is connected to the coin flap (12) as shown in the FIG. 3. The coin flap (12) is has two wings (12-1) connected at the center (12-3) with the solenoid valve (14). The angle (12-4) between the two wings (12-1) is 105 degree to facilitate rolling of the coin (8).
If the coin (8) inserted is proven as a validated by the processor (11), another signal is sent to the solenoid valve (14) to turn the coin flap (12) to a position open to a coin counter (15). The processor (11) sends a signal to turn on the coin counter (15) and to turn on the electronic timer (16) for 30 seconds. The electronic timer (16) is connected to the microprocessor (11) and to the main power switch (17) of the bidet. The coin (8) is dropped into a coin collector box (15-1). If the counter (15) does not sense a coin (8), the micro processor (11) recognizes it as to remain the all the power as it was.
If the counter (15) senses a coin (8), the microprocessor (11) check the time if 30 seconds are lapsed since the last coin is detected. If 30 seconds are not lapsed, the micro processor (11) sends a signal to the timer (16) to add another 30 seconds to the time left. The electric power to the bidet remains “ON”.
If 30 seconds are lapsed, the microprocessor sends a signal to supply electric power to the main power switch (17) of the bidet (1) for 30 seconds.
If the user wants to clean with water, the user push the “water” button (18) placed on the control board (19) of the bidet (1). If the user wants to dry with hot air, the user pushes the “air” button (20).
