Description

[Detailed description of the device] [Industrial applications]

This invention relates to a flush toilet cleaning system. In particular, it relates to a purification system that filters and circulates wash water for a toilet bowl and reuses it many times.

[Prior art and its problems]

A cleaning system for flush toilets that circulates and reuses toilet flush water has been developed. This purification system has an advantage that the amount of tap water used can be significantly reduced because water is effectively reused. In addition, since the sewage is not drained, it can be used even in places where there is no complete sewer. This purifying system for flush toilets cleans the dirty water that has been used to wash the toilet bowl, and supplies it to the toilet bowl again with a circulation pump to use it as washing water. The toilet bowl wash water is primarily filtered in the toilet bowl. Thereafter, the BOD is further filtered by the filter member until the BOD becomes about 5. The filtered purified water is stored in the storage tank. The suction side of the circulation pump is connected to the reservoir. The discharge side of the circulation pump is connected to the cis tank. A certain amount of purified water is stored in the storage tank. Purified water in the storage tank is returned to the storage tank through the circulation pump, the cis tank, the toilet bowl, the toilet tank, and the filtering member. Since this system circulates the water without draining it, it is necessary to vaporize and remove the water equivalent to the large stool volume and the small stool volume. This is because stool and urine are added to water to increase the water content by an amount equivalent to that. Conventional systems use heaters to vaporize the water. The heater heats the purified water and forcibly vaporizes it. However, the heater has a drawback that purified water cannot be vaporized and lost efficiently over a long period of time. This is because the heater cannot vaporize the pure water and vaporize and eliminate the foreign matter contained in the purified water. That is, the heated water vaporizes and disappears, but the foreign matter contained in the water remains without being vaporized and adheres to the inner surfaces of the heater and the heating chamber. The scale attached to the heater serves as a heat insulating material and reduces the thermal conductivity of the heater. In the heater covered with the scale, the amount of water vaporized per power consumption is significantly reduced. Therefore, it is necessary to regularly remove the scale attached to the surface of the heater. Removing the scale is extremely time-consuming. This is because the scale becomes hard and adheres to the surface of the heated heater. Furthermore, cleaning the heater is highly discouraged for its intended use. This is because the heater is provided in the flush water channel for stool and urine. Further, the water vaporized by heating with the heater has a harmful effect that a bad odor is easily generated in the surroundings. This invention was developed to solve these drawbacks, and an important purpose of this invention is to prevent the occurrence of scale, thereby simplifying the maintenance and inspection work,
Another object of the present invention is to provide a cleaning system for flush toilets that prevents the generation of offensive odors.

[Means for solving conventional problems]

The purifying system for a flush toilet of the present invention has the following configuration in order to solve the conventional problems. The purifying system of the flush toilet purifies the sewage sent from the toilet bowl 1 and returns it to the toilet bowl 1 by the circulation pump 2 to vaporize and eliminate the excess water. The purified water vaporizing means 3 includes an ultrasonic oscillator 4 for ultrasonically vibrating the purified water, and an ultrasonic power source 5 for vibrating the ultrasonic oscillator 4. The ultrasonic rotator 4 atomizes the purified water and forcibly vaporizes it.

[Operation effect]

In the flush toilet purifying system of the present invention, the purified water is atomized by ultrasonic vibration to forcibly vaporize and disappear. Ultrasonic vibration vaporizes water efficiently, so it is also used in humidifiers. Water droplets scattered from the surface of the water into the air by ultrasonic vibration become extremely fine mist. At this time, the purified water is atomized with the inclusion of foreign matter. That is, the fog contains foreign matter in the purified water. Atomization by ultrasonic vibration
The purified water and the foreign substances contained in it cannot be separated. Therefore, the foreign matter contained in the purified water is atomized and disappears together, and the foreign matter does not gradually accumulate in the container that vaporizes the purified water. Therefore, the purification system of the flush toilet of this invention is
Like the conventional heater, it has the feature that maintenance and inspection for removing scale and foreign matter can be minimized at regular intervals and maintenance can be significantly simplified. Further, the purified water atomized by ultrasonic vibration is not heated and has a feature that it is unlikely to cause a bad odor. Furthermore, the forced vaporization by ultrasonic vibration can vaporize the purified water more efficiently than the heater. This is because it is not necessary to apply a large amount of heat of vaporization heat energy to water, unlike the heater. Therefore, there is also a feature that the amount of vaporized purified water can be increased with a small amount of power consumption.

[Preferred embodiment]

An embodiment of the present invention will be described below with reference to the drawings. However, the examples shown below exemplify a cleaning system of a flush toilet for embodying the technical idea of the present invention.
The shape, structure, and arrangement are not specified in the structure below.
The purification system of this invention is subject to various modifications within the scope of the claims for utility model registration. Further, in this specification, in order to facilitate understanding of the scope of claims for utility model registration, the numbers corresponding to the members shown in the embodiment are
It is added to the members shown in "Column for requesting utility model registration", "Column for solving conventional problems" and "Column for action and effect". However, the members shown in the scope of claims for utility model registration are by no means limited to the members of the embodiment. The purifying system of the flush toilet shown in FIG. 1 purifies the sewage sent from the toilet bowl 1 and returns it to the toilet bowl 1 by the circulation pump 2 to vaporize and eliminate the excess water. This purification system uses 1 sewage from the toilet 1.
Next, a sewage tank 6 to be filtered, a filtering member 7 that clarifies the water filtered by the stool tank 6, a reservoir tank 8 that stores the purified water filtered by the filtering member 7, and a purification that vaporizes the purified water in the reservoir tank 8. It is provided with a water vaporizing means 3 and a circulation pump 2 for supplying the purified water from the reservoir 8 to the cis tank 9. The circulation pump 2 is controlled by a water surface sensor 15 provided in the cis tank 9. The water level sensor 15 operates the circulation pump 2 when the water level of the cis tank decreases, and stops the operation of the circulation pump 2 when the water level becomes higher than a set value. The toilet tank 6 primarily filters the sewage sent from the toilet bowl 1 to deposit solid components such as stool and paper contained in the sewage. The filtering member 7 filters the water delivered from the toilet tank 6 to the extent that it can be reused. The filtering member 7 is preferably
Clarify the BOD of purified water to 5 or more. This device does not specify the structures of the toilet bowl 6 and the filter member 7. The toilet tank 6 and the filter member 7 may have any structure capable of clarifying the waste water so that it can be reused. The storage tank 8 stores the purified water at a constant level. If the water is not drained from the storage tank 8, the water surface level will gradually rise. This is because urine and stool are added to the circulating water. When the water surface level rises, the storage tank 8 drains excess water to the vaporizing means 3,
Keep the water level constant. For this reason, the overflow tank 10 is opened in the water tank 8 at the water surface level position. When the water surface level of the reservoir 8 becomes higher than the overflow port 10, the purified water overflows from here to the vaporizing means 3. The water level of the reservoir 8 is the overflow port 10
When it becomes lower than this, the purified water in the storage tank 8 does not overflow, and the water level does not decrease. The overflow port 10 controls the water surface level of the reservoir 8 within a certain range. In the purification system of FIG. 1, the reservoir 8 and the filter member 7 are separate bodies, but both can be integrated. The vaporization means 3 includes a vaporization tank 11, an ultrasonic transducer 4, an ultrasonic power source 5, a water surface sensor 12, and a float valve 13.
It has and. The overflow port 10 of the reservoir 8 is provided with a float valve 13
Is connected to the vaporization tank 11 via. The float valve 13 adjusts the amount of purified water supplied to the vaporization tank 11 to make the water surface level of the vaporization tank 11 constant. Therefore, the float valve 13 is opened when the water surface level of the vaporization tank 11 is lower than the set level, and closed when the water level is higher than the set level. In this way, when the float valve 13 controls the water surface level of the vaporization tank 11 to be constant, the ultrasonic transducer 4 can atomize purified water constantly and efficiently. This is because the atomization rate of the ultrasonic transducer 4 decreases if the water surface level of the vaporization tank 11 is too low or, conversely, too high. An ultrasonic transducer 4 is provided on the bottom surface of the vaporization tank 11.
The ultrasonic transducer 4 radiates ultrasonic waves toward the water surface and atomizes the purified water on the water surface. The ultrasonic oscillator 4 is an ultrasonic power source 5
Connected to and vibrated ultrasonically. In the ultrasonic transducer 4,
Anything that can convert electrical signals into mechanical ultrasonic vibrations can be used. The capacities of the ultrasonic oscillator 4 and the ultrasonic power source 5 determine the vaporization amount of purified water per hour. If the capacities of the ultrasonic oscillator 4 and the ultrasonic power source 5 are increased, the amount of vaporization can be increased. The daily purified water vaporization amount required of the vaporization means 3 is usually in the range of 10 to 40 / day. 1 of this amount of purified water
If it is vaporized in 24 hours a day, the amount of vaporization per hour is
400-1700cc / hour. In order to forcibly vaporize this amount of purified water, the ultrasonic oscillator 4 and the ultrasonic power source 5 having a capacity of 10 to 40 W are used. The ultrasonic power source 5 is controlled by the water surface sensor 12 of the vaporization tank 11. The ultrasonic transducer 4 is vibrated only when the vaporization tank 11 has purified water at a certain level or higher. When the water surface level decreases, the vibration of the ultrasonic rolling element 4 is stopped. When purified water of a set level or more is stored in the storage tank 8, it passes from the overflow port 10 through the float valve 13,
Purified water is supplied to the vaporization tank 11. Overflow port 1
When the water is drained from 0, the water surface level of the vaporization tank 11 becomes a certain level or higher, and the ultrasonic transducer 4 is vibrated. The drainage is stopped from the overflow port 10, and the vaporization tank 1
When the purified water of No. 1 is vaporized, the water surface level of the vaporization tank 11 is lowered and the vibration of the ultrasonic transducer 4 is stopped. The vaporization tank 11 is provided with a forced exhaust fan 14 in order to efficiently discharge the atomized purified water. The forced exhaust fan 14 has its exhaust side connected to an exhaust duct to forcibly discharge atomized purified water. In this way, when the purified water atomized by the forced exhaust fan 14 is exhausted, it can be efficiently vaporized.
