[0035]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a diagram showing a configuration example of an ultrasonic dissolving apparatus according to the present invention, in which a substance to be dissolved is dissolved in an ultrasonic wave propagation medium at a constant concentration. 1 is an ultrasonic radiation means, 2 is a substance to be dissolved, 3 is a water pipe, 4 is an ultrasonic propagation medium, 5 is an ultrasonic control unit, 6 is a controller, 7
Is a DC power supply, and 8 is a connection line. FIG. 2 is a diagram showing a more detailed configuration of the inside of the ultrasonic dissolving apparatus such as the ultrasonic radiating means driving power supply 5 and the controller 6, etc., 51 is an amplifier, 52 is an ultrasonic radiating section driving power supply, and 61 is A / A. A D converter, 62 is a memory as data storage means, and 63 is a central processing unit.

The operation of the ultrasonic dissolving apparatus configured as described above will now be described. First, let the target concentration of the dissolved substance be a. The state of the ultrasonic wave propagation medium and the required ultrasonic output value when the target density is set to a are stored in the memory 62 in advance as data. The central processing unit 63 takes in the state value obtained from the state sensor 9 and compares it with the data to obtain a necessary ultrasonic output. The central processing unit 63 controls the ultrasonic radiator driving power supply 52 so that the ultrasonic output is radiated from the ultrasonic radiator 1. The ultrasonic radiating section driving power supply 52 converts the input voltage into a frequency, amplifies the voltage, and applies a voltage to the ultrasonic radiating means 1. Therefore, the output of the ultrasonic wave can be controlled by making the voltage input to the ultrasonic radiating section driving power supply variable or the amplification degree variable.

The mechanism of dissolution of the substance to be dissolved by ultrasonic radiation is not known in detail, but is considered as follows. When strong ultrasonic waves are irradiated into water, pressure changes propagate in the water, but extremely large pressure drops and rises occur in a very short time. When the pressure drops, water and dissolved gas evaporate due to the rapid pressure drop, and fine bubbles called cavitation are generated. The bubble then becomes locally hot due to adiabatic compression the next time the pressure is increased. The temperature at this time is said to be several thousand degrees to ten thousand degrees, and it is known that various radicals are generated around this minute high-temperature spot. It is considered that the surface of the substance to be dissolved is physically or chemically dissolved due to the strong pressure fluctuation, high temperature, radicals and the like.

As the state value of water, for example, a flow rate can be used. The amount of the substance to be dissolved is substantially constant with respect to the flow rate. The lower the flow rate, the lower the efficiency and the higher the ultrasonic output. When the flow rate is zero, the dissolution is stopped, that is, the required ultrasonic output is set to zero. Therefore,
By storing the ultrasonic output values necessary for the flow rate as data such as a table or an approximate expression,
Even if the flow rate changes, an ultrasonic wave propagation medium having a constant concentration can be accurately generated.

FIG. 3 shows an application example 1 in which the first embodiment is applied to a disinfectant addition mechanism in a water heater with a bathtub water purification function. 100 is a bathtub, 101 is bathtub water, 102 is an ultrasonic dissolving device, 103 is a pump, 104 is a purification unit, 1
05 is a heat exchanger, 106 is a tap water introduction pipe, 107 is a circulation path, 108, 109, 111 and 112 are flow path switching valves,
110 is a bypass pipe, 113 is a drain pipe, 114 is an adapter having a filter function, 115 is a turbidity sensor, 116
Is a flow meter. In this case, an agent having a bactericidal action is used as the substance to be dissolved in the ultrasonic dissolving apparatus 102.
The operation of the water heater with a bathtub water purification function will be briefly described. When hot water is filled, the heat exchanger 105 and the tap water introduction pipe 10 are used.
6. Hot water is introduced into the bath water 100 through the ultrasonic dissolving device 102. At this time, the ultrasonic dissolving device 102 has not been operated yet. Bath tub water that has been contaminated by a person taking a bath enters a circulating purification mode automatically or at the instruction of the user. In the circulation mode, the pump 11
The bathtub water 101 sucked from the bathtub 4 is introduced into the purifying unit 104 and returned to the bathtub through the circulation path 107 so as to purify the bathtub water 101 by the action of the adapter 114 and the purifying unit 104. At this time, by operating the ultrasonic dissolving apparatus 102, the medicine can be added to the bath water having a constant concentration, and thereby the bath water can be sterilized.
Since the amount of bath water is usually 150 L to 300 L, if the ultrasonic dissolving device is operated for a predetermined time, it is possible to add the medicine into the bath water with an error of at most about twice.

The substance to be dissolved is irradiated with ultrasonic waves to be dissolved, so that the distance from the ultrasonic radiation means gradually increases,
Even if the same output ultrasonic wave is irradiated, the dissolution amount of the substance to be dissolved gradually decreases. Therefore, it is desirable to control the ultrasonic output based on the distance between the substance to be dissolved and the ultrasonic radiation means or the remaining amount of the substance to be dissolved. Here, the distance can be estimated by measuring the time until the ultrasonic wave radiated from the ultrasonic wave radiating means is reflected by the substance to be dissolved and returned. The propagation speed of ultrasonic waves in water is 15
When the distance increases by 0.75 mm, the distance changes by 1.5 mm in a reciprocating manner, and the delay time increases by 1 μs. If the relationship between the distance measured as described above and the required ultrasonic output with respect to the dissolution concentration is stored as data, the substance to be dissolved is accurately dissolved regardless of the distance between the substance to be dissolved and the ultrasonic radiation means. be able to. As the ultrasonic output, for example, the power consumption of the ultrasonic transducer can be used.

When the substance to be dissolved is carried on a nonwoven fabric or the like, the amount of the substance gradually decreases due to dissolution by ultrasonic waves,
The amount of dissolution from the substance to be dissolved changes even when the same ultrasonic wave is irradiated. In this case, it is also possible to irradiate an ultrasonic wave and measure the intensity of the reflected wave, and use it as an alternative parameter of the distance for controlling the dissolved concentration of the target substance.

The distance between the ultrasonic radiating means and the substance to be dissolved can be easily measured from the delay time until the ultrasonic wave is emitted for a very short time and the reflected wave is received. This is in principle the same as a so-called ultrasonic distance sensor. The ultrasonic wave in this case may have the same frequency as that for dissolving the substance to be dissolved, or may use a different frequency. The reception of the reflected wave is performed by measuring the voltage since an ultrasonic wave is applied to the ultrasonic wave radiating means composed of a piezoelectric vibrator, and a potential proportional to the magnitude of the ultrasonic wave is generated between the electrodes. The frequency of the ultrasonic wave for distance measurement may be the same as or different from the ultrasonic wave for dissolving the substance to be dissolved, but it is preferable to use the resonance frequency of the piezoelectric vibrator. In that case, it becomes possible to irradiate the ultrasonic wave efficiently. Different frequencies can be used for the ultrasonic waves for distance measurement and the ultrasonic waves for dissolving the substance to be dissolved. In that case, it becomes possible to use a more suitable ultrasonic frequency for measuring the distance. Also,
It is desirable that the irradiation time of the ultrasonic wave be shorter than the delay time until the ultrasonic wave is reflected. This makes it possible to measure the distance stably without interference between the emitted ultrasonic wave and the reflected wave.

In the case of the present embodiment, it is more desirable that the target concentration to which the drug is added is variable depending on the turbidity. It is said that there is a correlation between turbidity in water and bacterial count. That is, since the turbidity increases as the number of bacteria increases, the number of bacteria can be managed using the turbidity as a guide. For example, turbidity is 0.5
When the number exceeds 1, the addition of the drug is started. When the number exceeds 1, the number of bacteria is increasing. These relationships may be stored in the data storage means as a table, or the relationship between the turbidity and the amount of the drug added may be stored as a mathematical expression and controlled by that.

FIG. 4 is a flow chart showing the flow of the operation of the routine for dissolving the substance to be dissolved in the above embodiment. The dissolution routine is started at a predetermined timing by a timer, for example. First, measure the turbidity in S1,
In S2, the target dissolution concentration of the substance to be dissolved is determined from the turbidity value and Table T1 in the memory. Next, in S3, a necessary dissolution amount C1 is determined from the current dissolution target substance amount C and the target concentration value. Here, if there is a bathtub water amount detection means, its output value may be used, or V may be set as a constant value, for example. Assuming that the bathtub water volume is V, it can be obtained by the following equation. If C1 is equal to or less than 0 in C1 = V * target concentration value-CS4, dissolution is not necessary, and this routine is terminated, and the dissolution routine is stopped until the next timing. In S5, the flow rate Q is measured, and in S6, the distance L between the ultrasonic irradiation means and the substance to be dissolved is measured. Next, in S7, the ultrasonic output P and the dissolution time T are determined from Table 2 in the memory from the distance L and the required dissolution amount C1. S8, S9,
In S10, if the set time T is longer than the predetermined minute time t0, an ultrasonic wave is emitted at the output P for the time t0. When the time T is shorter than t0, an ultrasonic wave is emitted at the output P for the time T. In S11, the dissolution amount is calculated based on the irradiation time, and the current dissolution amount C is updated. The above processing is returned to S1 as one routine, and the same processing is performed until the current dissolution amount reaches the necessary dissolution amount or until a stop command is interrupted.

In the present embodiment, a drug having a bactericidal property is used as a substance to be dissolved. However, an antibacterial metal such as copper, silver or zinc, or a ceramic or resin containing these, a metal oxide or a metal salt, etc. A conductive material can be used.

FIG. 5 shows a shower unit of a second application example to which the ultrasonic dissolution apparatus of the present invention is applied. Usually, tap water or hot water obtained by heating tap water is used as the shower water. In recent years, as this shower unit, a shower unit having a dechlorination function for discharging dechlorinated water has been put on the market. This application example realizes a shower unit that has a drawback of conventional products, in which the concentration of the substance to be dechlorinated can be freely controlled and the dechlorination function has a long life.

Water is supplied to the shower head 204 by the hose 203 and water is supplied from the shower head in a shower shape. The substance to be dissolved in the ultrasonic dissolving apparatus 202 is ascorbic acid, and since ascorbic acid has a reducing property, it is easily linked to residual chlorine in tap water, and removes residual chlorine. The ascorbic acid in this case is desirably subjected to a treatment for making it hardly soluble. The method of the insolubilization treatment can be performed, for example, by derivatization. In the case of this shower unit, since the substance to be dissolved can be dissolved only when water is used, there is no waste of the substance to be dissolved, and the shower unit for supplying dechlorinated shower water can have a longer life or a more compact size. it can. Further, since the amount of dissolution can be easily changed according to the flow rate, the same concentration of the substance to be dissolved can always be dissolved even when the flow rate changes, and a stable dechlorination action can be exhibited. Further, as the substance to be dissolved, a reducing substance such as a sulfite or a nitrite can be used in addition to ascorbic acid.

FIG. 6 shows a hot water washing toilet seat of a third application example to which the ultrasonic dissolving apparatus of the present invention is applied. The hot water flush toilet seat is used to clean a local area after stool use in a toilet and to maintain local sanitation. Incorporating the ultrasonic dissolving apparatus of the present invention into this warm water flush toilet seat and using a reducing substance such as sulfite, nitrite, or ascorbic acid as a substance to be dissolved, it is possible to perform dechlorination of the local flush water, which is more stimulating. Local cleaning can be performed comfortably with a small amount of cleaning liquid. In addition, a constant concentration of dechlorinated substance can be always added irrespective of the flow rate, and when not in use, there is no elution of the dechlorinated substance, so that a warm-water flush toilet seat with a longer life can be provided. The operation will be described with reference to FIG. 6. When the user presses an unillustrated washing switch, the water shutoff valve 301 draws tap water into the warm water washing toilet seat, the water amount adjustment valve 303 adjusts the flow rate, and The cleaning water is heated by the heat exchanger, and the cleaning water is dechlorinated by dissolving the dechlorinated substance at an appropriate concentration with the ultrasonic dissolving device 306, and the dechlorinated cleaning water is discharged from the local cleaning nozzle 307.
