Abstract

PURPOSE:To completely remove dirt stuck to a toilet bowl by flushing water and ultrasonic vibration by a method wherein an occupancy-detecting means that senses the state of occupancy when a person comes to use the toilet is provided, and ultrasonic vibration is given, when the detection is made, to the toilet bowl while water is supplied to the toilet bowl from a water supply device. CONSTITUTION:When a person sits on a toilet seat 1a of a toilet bowl 1, a detecting switch 8 is turned on, and a signal from the detecting switch is inputted into a microcomputer 9. Then the microcomputer 9 sends the said signal to a driving circuit 10, and thereby a solenoid valve 4 is actuated. As the microcomputer 9 sends signals to an ultrasonic transmitter 7, the ultrasonic transmitter 7 sends high frequency electric power to an ultrasonic oscillator 6. Then, while flushing water is allowed to flow inside the toilet bowl 1 by operation of the solenoid valve 4, the toilet bowl is given ultrasonic vibration by the ultrasonic oscillator 6, and thereby dirt stuck to the toilet bowl 1 is removed. Thereby the toilet bowl 1 is always kept clean without depending on manual washing.

0002

2. Description of the Related Art Generally, in a flush toilet, when a person relieves himself or herself, a lever of a water supply device is rotated to supply water to the toilet for flushing.

0003

[Problem to be Solved by the Invention] However, it is not possible to clean the toilet bowl simply by flushing the water, so a solution containing detergent must be applied to the toilet bowl to scrub away the filth, and in order to keep the toilet bowl clean, , daily manual cleaning was required.

0004

[Means for Solving the Problems] The present invention provides a flush toilet made of porcelain, metal, etc. equipped with a water supply device.
an ultrasonic vibrator attached to, fixed to, or built into one or more places of the toilet; a power supply means for supplying high-frequency power to the ultrasonic vibrator; and water supplied from the water supply means. water control means for controlling supply; and toilet use detection means for detecting use of the toilet; when the use of the toilet is detected by the toilet use detection means, the water control means supplies water to the toilet. At the same time, the power supply means supplies high frequency power to the ultrasonic vibrator to supply ultrasonic waves to the toilet bowl, thereby cleaning the toilet bowl.

[0005]

[Operation] In the present invention, when a person uses the toilet, the toilet use detection means detects this, and the water supply means operates to flush water from the water supply device, and the power supply means transmits high-frequency power to the toilet. The toilet bowl can be automatically cleaned by supplying it to an ultrasonic vibrator to cause the toilet bowl to vibrate ultrasonically.

[0006] In this way, since the toilet bowl is powerfully cleaned by ultrasonic vibration, the toilet bowl can always be kept clean without relying on manual cleaning.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram of an ultrasonic toilet according to the present invention, in which a water supply pipe 2 is connected to the toilet bowl 1, and an ordinary water supply device 3 is attached to the upper part of the water supply pipe 2.

[0008] Also, a solenoid valve 4 is connected in the middle of the water supply pipe 2, and this solenoid valve 4 is supplied with electric power from a control device 5.

Furthermore, an ultrasonic transducer 6 is glued to an appropriate location on the toilet bowl 1, and an ultrasonic transmitting device 7 is attached to the ultrasonic transducer 6.
This ultrasonic transmitting device 7 is connected to the control device 5.

Further, a detection switch 8 is attached to the toilet seat 1a of the toilet bowl 1, and this detection switch 8 is connected to the control device 5.

FIG. 2 is a block diagram of a control device for controlling the ultrasonic toilet of the present invention. The detection switch 8 is connected to the microcomputer 9 of the control device 5, and the ultrasonic transmitting device 7 is connected to the microcomputer 9. Via ultrasonic transducer 6
is connected to the microcomputer 9, and the solenoid valve 4 is further connected to the microcomputer 9 via a drive circuit 10.

Next, to explain the operation of this embodiment, first, when a person sits on the toilet seat 1a of the toilet bowl 1, the detection switch 8 is turned on, and when the signal is input to the microcomputer 9, the microcomputer 9 operates the solenoid valve 4 by supplying a signal to the drive circuit 10.

Further, when the microcomputer 9 supplies a signal to the ultrasonic transmitter 7, the ultrasonic transmitter 7 supplies high frequency power to the ultrasonic transducer 6.

In this way, the operation of the solenoid valve 4 causes the toilet bowl 1 to
As water flows through the toilet bowl 1 and the ultrasonic vibrator 6 ultrasonically vibrates the toilet bowl 1, dirt adhering to the toilet bowl 1 can be removed.

[0015] In this way, the ultrasonic toilet of this embodiment has the following features:
When a person uses the toilet, water automatically flows and the ultrasonic vibrator 6 vibrates the toilet bowl 1 to remove dirt, so there is no need to manually clean the toilet bowl afterwards.

[0016] As a means for detecting the use of the toilet, the toilet seat 1a
A detection switch 8 is attached to the toilet seat 1 to detect when a person sits on the toilet seat 1a.
It may also be installed near a person to detect a person.

Further, the toilet bowl 1 may be made of porcelain, metal, etc., and the ultrasonic vibrator 6 may be fixed to an appropriate location of the toilet bowl 1 or embedded in an appropriate location of the toilet bowl 1. Furthermore, the number of ultrasonic transducers 6 is not limited to one, but may be two or more.

FIG. 3 is a block diagram of an ultrasonic toilet according to another embodiment of the present invention, in which 1 is a toilet bowl, 2 is a water supply pipe, 3 is a water supply device, 5 is a control device, and 6 is an ultrasonic vibrator. , 7 is an ultrasonic transmitter, and 9 is a microcomputer, and since these structures are the same as those in the above embodiment, their explanations will be omitted.

In this embodiment, the water supply device 3 is provided with a lever 11 that rotates when a person relieves himself, and a water supply detection device 12 is connected to the water supply pipe 2 instead of the solenoid valve 4. The output of this water supply detection device 12 is input to the microcomputer 9 of the control device 5, and the solenoid valve 4 and its drive circuit 10 are omitted.

In this embodiment configured as described above, when a person relieves himself and turns the lever 11 of the water supply device 3, water flows from the water supply device 3 to the toilet bowl 1. It is detected by the supply detection means 12, and this detection signal is input to the microcomputer 9 of the control device 5.

When the water supply detection signal is input to the microcomputer 9, the ultrasonic transmitting device 7 operates and supplies high frequency power to the ultrasonic vibrator 6, so that the ultrasonic vibrator 6 crosses the toilet bowl 1. Sound waves vibrate.

In this way, the water flowing from the water supply device 3 is detected and high frequency power is supplied to the ultrasonic vibrator 6 to cause the toilet bowl 1 to vibrate ultrasonically, so that the toilet bowl 1 is automatically cleaned and filth is removed. has the advantage that it is removed.

[0023]

[Effects of the Invention] As explained above, in the ultrasonic toilet of the present invention, by supplying water to the toilet and at the same time ultrasonically vibrating the toilet with an ultrasonic vibrator, dirt adhering to the toilet can be removed by water flow and ultrasonic waves. The dirt is removed by vibration, so there is no need to manually remove the dirt, which has the advantage of being able to keep it clean at all times.
