Description

Technical Field

[0001] The present invention relates to a dilution display device, particularly an electrolytically generated hypochlorous acid water (hereinafter also simply referred to as "electrolytically generated hypo water") obtained by electrolyzing salt water, or a commercially available sodium hypochlorite solution, etc. The bactericidal disinfectant is diluted based on the tap water flow rate, and while displaying the chlorine concentration of the diluted water, an electrolytically generated hypo water or a commercially available sodium hypochlorite solution dilution display device that discharges diluted water of the same concentration from a faucet is disclosed. The electrolytically generated hypo water and sodium hypochlorite solution targeted by the present invention are bactericidal disinfectants recognized as bactericides for food additives used in the kitchen as disinfectants for food materials, food and beverage containers, equipment, etc.

Background Art

[0002] Regarding this type of dilution device, for example, the one disclosed in Japanese Utility Model Publication No. 56-81731 is known. The disclosure in Japanese Utility Model Publication No. 56-81731 relates to a device named "Disinfectant Concentrate Dilution Device," and aims to "provide a disinfectant concentrate dilution device that can arbitrarily dilute or mix disinfectant concentrate with tap water, and can always be kept clean and easily used or maintained" (see page 2, line 20 to page 3, line 3 of the same publication specification), and is configured such that "an inlet pipe having a joint that can be attached to a water tap is connected to a jet pump, and discharge pipes scattered on the same axis as the inlet pipe and at opposing positions are connected to the jet pump, the jet pump is in communication with a suction device formed to suck up disinfectant concentrate contained in a container attached to the discharge pipe by the negative pressure generated by the jet of tap water, and the suction pipe is equipped with a valve to adjust the flow rate of the disinfectant concentrate" (see the same publication specification). (See Claims for New Patent Registration) "The entire device can be suspended from a snake 1 for use, the entire device can maintain a good vertical position without tilting, the replacement of the stock solution A and cleaning of the container are easy, maintenance is easy, and furthermore, a valve for adjusting the flow rate is provided so that the dilution of the disinfectant stock solution can be changed as needed, and furthermore, hands can be disinfected in a running liquid along with tap water so that cleanliness can always be maintained, and also, hands can be washed by running only tap water, and it is possible to arbitrarily select the desired disinfectant stock solution, and in some cases, it is possible to mix and use each disinfectant stock solution A and B" (See page 5, line 6 to page 6, line 12 of the Specification of the Publication).

[0003] Figure 4 is a longitudinal cross-sectional view showing the first embodiment of the disclosed invention, which is attached as Figure 1 to All Japan Utility Model Publication No. 56-81731. In Figure 4, reference numeral 101 denotes a faucet, 102 a pipe inlet, 103 a joint, 104 a jet pump, 105 a pipe discharge, 106 a container, 112 a valve, 115 a suction pipe, and A a disinfectant concentrate (the reference numerals have been changed to three-digit numbers in the 100s by the applicant to indicate that they are prior art).

[0004] The applicant has already proposed Utility Model Registration No. 3241138 (invention title: "Water Tap Direct Connection Electrolytically Generated Water Chlorine Concentration Display Mixer") when devising this type of water tap direct connection dilution device, and the present invention utilizes the water tap direct connection electrolytically generated water chlorine concentration display mixer used in Utility Model Registration No. 3241138 to use electrolytic hypochlorous acid water (concentrate) produced by the electrolytic hypochlorous acid water generator (CL-S60B) manufactured and sold by the applicant, with the chlorine concentration displayed and used directly connected to the water tap, in the same way as the electrolytic hypochlorous acid water generator. It is essentially a general-purpose electrolytic water generator that detects the amount of tap water dispensed when the tap is turned on, and based on the detection result, displays the chlorine concentration on the above-mentioned display mixer (for example, 50, 100, 200 ppm) while dispensing diluted water of the same concentration.

[0005] Figure 5(a) shows the external appearance of the water tap-connected electrolytic water chlorine concentration display mixer proposed by the applicant, as registered in Utility Model No. 3241138, and Figure 5(b) is a schematic cross-sectional view when a hose cap for an extension hose is attached to the discharge outlet. Figure 6 is a schematic diagram showing the overall layout of an electrolytic hypochlorous acid water generator consisting of components such as a saltwater tank, pump, and electrolytic cell that use the concentration indicator mixer. In Figures 5(a)(b) and 6, reference numeral 200 denotes the electrolytic hypochlorous acid water generator, 201 denotes the saltwater tank, 202 denotes the main body of the device, 203 denotes the indicator mixer, 204 denotes the water tap, and 205 denotes the indicator lamp area of ​​the indicator mixer (the reference numerals have been changed to three digits in the 200s by the applicant to indicate that they are prior art).

[0006] However, the electrolytic hypochlorous acid water generator 200, which uses the mixing indicator 203 of the invention related to Utility Model Registration No. 3241138, generates electrolytic hypochlorous acid water only when used for disinfecting food ingredients, food and beverage containers, equipment, etc., and at other times the entire device remains inactive, making it inefficient. Furthermore, when disinfecting food ingredients, food and beverage containers, equipment, etc., disinfection is not always limited to electrolytic hypochlorous acid water alone. At times, it may be desirable to use a commercially available disinfectant solution approved as a food additive, such as sodium hypochlorite solution (for example, Purelax (registered trademark No. 703738) (chemically sodium hypochlorite solution)), diluted as appropriate.

[0007] Furthermore, in order to meet both of these purposes, when storing pre-generated electrolyzed hypochlorous acid water or commercially available disinfectant solutions and using them for disinfecting food ingredients themselves or food containers and equipment, it is desirable that the chlorine concentration be appropriate for the disinfection and sterilization purpose of the food ingredients. Therefore, appropriately diluting the solution and displaying the chlorine concentration of the diluted solution discharged from the tap would be efficient and reassuring in the disinfection and sterilization of food ingredients, food containers and equipment, etc. [Prior art documents] [Patent Documents]

Embodiments for Carrying Out the Invention

[0013] Based on the drawings showing an embodiment as a form for implementing an electrolytically generated hypochlorous acid water or commercially available sodium hypochlorite solution dilution display device (hereinafter, also simply referred to as "dilution display device") according to the present invention, it will be described in detail.

Example

[0014] FIG. 1 is a diagram showing a schematic configuration of a dilution display device according to Example 1, which is an example of the dilution display device according to the present invention, and FIG. 2 is a dilution flow diagram of the dilution display device according to Example 1. In FIGS. 1 and 2, reference numeral 1 denotes a dilution display device according to Example 1 of the present invention, 2 denotes a stock solution tank, 3 denotes a relay machine, 4 denotes a water tap direct connection electrolytically generated water chlorine concentration display mixer according to Utility Model Registration No. 3241138 (hereinafter, also simply referred to as "mixer 4"), 5 denotes a control board in the relay machine 3, and a program such as a procedure of the dilution flow is stored therein. And reference numeral 6 denotes a pump driven by a DC motor, 7 denotes a three-way valve, 8 denotes a flow sensor for detecting the flow rate of tap water, 9 denotes a dilution concentration selection switch for electrolytically generated hypochlorous acid water dilution and sodium hypochlorite solution dilution, and 10 denotes a switch for selecting an electrolytically generated hypochlorous acid water stock solution and a sodium hypochlorite stock solution.

[0015] As shown in FIGS. 1 and 2, the dilution display device 1 according to Example 1 dilutes the generated electrolytically generated hypochlorous acid water stock solution or commercially available sterilizing and disinfecting solution stored in the stock solution tank 2 using the mixer 4 described above, dilutes it to a desired chlorine concentration suitable for disinfection of food, drinking containers, equipment, etc. and container sterilization, and discharges it from the water tap while displaying the chlorine concentration of the diluted water. As shown in FIG. 1, the dilution display device 1 according to Example 1 is composed of three members: a stock solution tank 2, a relay machine 3, and a mixer 4. That is, the stock solution tank 2 is a tank for storing the generated electrolytic hypochlorous acid stock solution or commercially available sterilizing and disinfecting solutions. The mixer 4 is installed at a faucet, and the stock solutions stored in the stock solution tank 2 are respectively connected by a piping hose and a control line, and are configured to be diluted, displayed, and discharged according to the flow shown in FIG. 2.

[0016] And the pump 6 used in the dilution display device 1 according to the first embodiment is a pump using a DC motor that is easy to control the flow rate of the stock solution (actually a tube pump using a DC motor), and a certain amount (50 (mL)) of the stock solution is sent in, or by controlling the ON / OFF of the DC motor and the duty ratio of the DC motor (the ratio of the time when the pulse is on to the time when the pulse is off), the feed amount of the stock solution is sent out based on the tap water flow rate of the display 4 and diluted. In addition, in the dilution display device 1 according to the first embodiment, as a modified example, it is not prevented to provide a sensor for notifying the amount of the stock solution in the stock solution tank 2.

[0017] (Dilution of electrolytic hypochlorous acid) In the dilution display device 1 according to the first embodiment, the electrolytic hypochlorous acid generated by a separate electrolytic hypochlorous acid generator is diluted with tap water. However, when taken out from the electrolytic hypochlorous acid generator, it has a chlorine concentration of approximately 6000 ppm. Therefore, hereinafter, the chlorine concentration of the electrolytic hypochlorous acid will be described as 6000 ppm.

[0018] (Concept of dilution in the dilution display device 1 according to the first embodiment) In the dilution display device 1 according to the first embodiment, a stock solution of electrolytic hypochlorous acid having a chlorine concentration of approximately 6000 ppm is used with the faucet-direct-connected electrolytic hypochlorous acid chlorine concentration display mixer according to the utility model registration No. 3241138, and is controlled by the same program as diluting the electrolytic hypochlorous acid generated by a separate electrolytic hypochlorous acid generator with tap water on the control board in the relay unit 3 (supply a certain flow rate of the stock solution with a DC motor pump, vary the tap water flow rate supplied from the faucet to obtain diluted water), and diluted water with chlorine concentrations of 50 ppm, 100 ppm, and 200 ppm can be obtained.

[0019] The basic dilution flow of the dilution display device 1 according to this embodiment 1, including the exchange of tap water flow rate detection signals and the delivery of the undiluted solution, is as follows. (a) By opening the water tap, the water flow rate is detected by the mixer 4 which is directly connected to the tap. (b) Based on the detection of tap water flow rate, the relay unit's pump starts drawing the concentrate (electrolyzed hypochlorous acid water) from the concentrate tank. (c) Based on the detected tap water flow rate, the pump is driven and a certain amount of undiluted liquid is sent to the mixing display unit 4. (d) Mixing indicator 4 mixes the concentrate with tap water to dilute, displays a lamp indicator, and dispenses the solution. Furthermore, the amount of water required to obtain diluted water with a predetermined chlorine concentration by mixing this type of tap water with a stock solution of a predetermined chlorine concentration can be calculated using the following formula.

[0020]

number

[0021] Based on this formula, in the dilution display device 1 according to this embodiment 1, for example, if 8.33 mL / min of electrolyzed hypochlorous acid water with a chlorine concentration of 6000 ppm (0.6%) is mixed with tap water flowing at a flow rate of 1.0 L / min, a 50 ppm dilution can be produced. Similarly, if 16.67 mL / min of electrolyzed hypochlorous acid water with a chlorine concentration of 6000 ppm is mixed with tap water flowing at a flow rate of 1.0 L / min, a 100 ppm dilution can be produced, and if 33.34 mL / min of electrolyzed hypochlorous acid water with a chlorine concentration of 6000 ppm is mixed with tap water flowing at a flow rate of 1.0 L / min, a 200 ppm dilution can be produced. Furthermore, by mixing 16.67 mL / min of electrolyzed hypochlorous acid water with a chlorine concentration of 6000 ppm with tap water flowing at a flow rate of 2.0 L / min, a 50 ppm dilution solution can be produced. Similarly, by mixing 33.34 mL / min of electrolyzed hypochlorous acid water with a chlorine concentration of 6000 ppm with tap water flowing at a flow rate of 4.0 L / min, a 50 ppm dilution solution can also be produced.

[0022] (Example of lamp display for mixer 4 in the above dilution flow) In the mixer 4 of the dilution display device 1 according to this embodiment 1, the display is shown using the three leftmost lamps (50 ppm lamp, 100 ppm lamp, and 200 ppm lamp) of the four lamps shown in Figure 5. However, in the dilution display device 1 according to this embodiment 1, the inflow rate of tap water is not necessarily constant and fluctuates due to various factors. Furthermore, the chlorine concentration of the diluted water also fluctuates accordingly, and there is a time lag involved, so the display of the chlorine concentration of the diluted water must also accommodate these fluctuations. In other words, the display of the chlorine concentration of the diluted water will have a certain range (display range). Therefore, in the lamp display of the chlorine concentration of the diluted water in the dilution device 1 according to this embodiment 1, the display is made as follows, taking into consideration these fluctuations and the time lags associated with these fluctuations.

[0023] [Table 1]

[0024] Table 1 shows specific examples of the lamp display in the dilution display device 1 according to this embodiment 1 when electrolytically produced hypochlorous acid water (chlorine concentration 6000 ppm) introduced into the stock tank 2 is diluted. In other words, the lamp display of the mixer 4 of the dilution display device 1 according to this embodiment 1 enables the display of chlorine concentration by using a combination of three indicator lamps, such as a 50 ppm lamp, a 100 ppm lamp, and a 200 ppm lamp, which are lit individually or simultaneously. A specific example of this display is shown below.

[0025] For example, if the tap water flow rate is 0.8 (L / min) to 1.8 (L / min) and the chlorine concentration is 375.0 ppm to 166.7 ppm, the 200 ppm lamp will light up alone. If the tap water flow rate is 1.8 (L / min) to 2.2 (L / min) and the chlorine concentration is 166.7 ppm to 136.4 ppm, the 200 ppm lamp and the 100 ppm lamp will light up simultaneously. If the tap water flow rate is 2.2 (L / min) to 3.4 (L / min) and the chlorine concentration is 136.4 ppm to 88.2 ppm, the 100 ppm lamp will light up alone. When the water flow rate is 3.4 L / min to 4.5 L / min and the chlorine concentration is 88.2 ppm to 66.7 ppm, the 100 ppm and 50 ppm lamps are illuminated simultaneously. When the water flow rate is 4.5 L / min to 6.5 L / min and the chlorine concentration is 66.7 ppm to 46.2 ppm, the 50 ppm lamp is illuminated alone. When the water flow rate is 6.5 L / min to 7.0 L / min and the chlorine concentration is 46.2 ppm to 42.9 ppm, the 50 ppm lamp is flashed alone to warn of a low concentration. The values ​​shown as "conventional" in Table 1 are included for convenience to show the relationship between the indicator lamp display for chlorine concentration of the dilution water used in mixer 203, a device related to utility model registration No. 3241138, and the actual concentration display.

[0026] (German dilution method) Figure 3 is a graph showing the correlation between the duty cycle of the DC motor and the discharge flow rate (mL / min) of the pump 6 that uses it. The dilution display device 1 according to this embodiment 1 controls the discharge of the undiluted solution from the pump 6 using a DC motor, which is easy to control the flow rate, based on the tap water flow rate from the display unit 4 directly connected to the water tap. Therefore, in order to dilute with tap water at a predetermined flow rate to obtain a 100 ppm diluted solution, for example, when the tap water flow rate is approximately 1.0 mL / min as shown in Figure 3, the pump 6 using the DC motor of the dilution display device 1 according to this embodiment 1 should be configured to deliver a stock solution flow rate of approximately 15 mL / min, and the DC motor should be driven and controlled with a duty cycle of approximately 30%, as shown in Figure 3. Similarly, when the tap water flow rate is 3.0 mL / min, a stock solution flow rate of approximately 45 mL / min should be delivered, and the DC motor should be driven and controlled with a duty cycle of approximately 65%. In this manner, the dilution display device 1 according to this embodiment 1 drives and controls a DC motor based on the water flow rate from a mixer 4 directly connected to a water tap to produce diluted water with chlorine concentrations (for example, 50 ppm, 100 ppm, 200 ppm), displays the chlorine concentration, and discharges it from the water tap.

[0027] The dilution flow of the dilution display device 1 according to this embodiment 1, which is based on the exchange of tap water flow rate detection signals and the delivery of the undiluted solution, is as follows. (a) The repeater's concentrate type selection switch 10 is used to select whether the liquid in the concentrate tank 2 is 6000 ppm electrolyzed water or 60000 ppm commercially available sodium hypochlorite. (b) Press switch 9 on the repeater to display the chlorine concentration of the mixer and select the desired chlorine concentration. (c) By opening the water tap, the water flow rate is detected by the mixer 4 which is directly connected to the tap. (d) Based on the detection of tap water flow rate, the pump of the relay unit starts drawing the concentrate (electrolyzed hypochlorous acid water) from the concentrate tank. (e) Based on the detected tap water flow rate, the pump is driven at a duty cycle proportional to the chlorine concentration and the undiluted solution is sent to the mixing display unit 4. (f) The concentrate and tap water are mixed and diluted using the mixing indicator 4 and then dispensed. In other words, the basic operation involves selecting the concentrate type selection switch 10 to 60,000 ppm, which causes the pump 6 to operate intermittently (operating and stopping repeatedly), thereby reducing the discharge volume to approximately half of that of continuous operation. Furthermore, the aforementioned duty cycle control ensures that the concentrate is added at a pump discharge rate corresponding to the amount of tap water, allowing the system to handle changes in the concentration of the concentrate even when using the same pump.

[0028] In the dilution display device 1 according to this embodiment 1, a switch 9 lights up a lamp that displays the desired chlorine concentration of the diluted water (for example, 50 ppm). When the water tap is turned on (opened), the built-in flow sensor 8 detects the water flow rate. Based on this detection result, as described above, the DC motor is driven at a duty cycle corresponding to the lamp display to discharge diluted water with the chlorine concentration (for example, 50 ppm) displayed on the lamp from the water tap. Then, if the tap is turned on or off while the water is being discharged from the tap, the flow sensor 8 of the mixer 4, which is directly connected to the tap, detects the flow rate of the tap water each time, sends the tap water flow rate value to the relay unit 32, and controls the flow rate of the pump 6 as described above to mix and dilute the water with the tap water, maintaining the chlorine concentration of the discharged diluted water (for example, 50 ppm) and discharging it (detailed explanations for dilutions of 100 ppm, 200 ppm, etc. are omitted, but the flow is the same). These dilution flows are stored as a program on the control board 5 of the relay unit 3 of the dilution display device 1 according to this embodiment 1, and are executed as appropriate.

[0029] (Indication of chlorine concentration in the diluted water for specific dilution methods) Next, in the dilution display device 1 according to this embodiment 1, the display of the chlorine concentration of the diluted water diluted by the dilution method described above on the mixer 4 will be explained. In the dilution display device 1 according to this embodiment 1, pressing the button on the relay switch 9 (concentration selection) once causes the chlorine concentration indicator lamp (50 ppm) on the mixer 4 to light up independently. Pressing it twice causes the chlorine concentration lamp (100 ppm) to light up independently. Pressing it three times causes the chlorine concentration lamp (200 ppm) to light up independently. Based on the detection value of the tap water flow sensor on the mixer 4, the flow rate of the pump 6 is controlled based on the duty cycle of the DC motor to dilute the electrolytically produced hypochlorous acid water with a chlorine concentration of 6000 ppm. The diluted water is then discharged with a chlorine concentration corresponding to the display on the chlorine concentration indicator lamps (50 ppm lamp, 100 ppm lamp, 200 ppm lamp) on the mixer 4. If there is a malfunction such as a significant fluctuation in the tap water flow rate or exceeding the capacity of the DC motor pump, the concentration indicator lamps will flash or a buzzer inside the relay will sound to notify the user.

[0030] In other words, for example, if you want to dilute to 50 ppm using the above flow, if the tap water flow rate is between 2.2 (L / min) and 6.8 (L / min), the control board in the relay will proportionally control the DC motor pump (variable duty cycle from 30 to 90) to send a stock solution (chlorine concentration of 6000 ppm) proportional to the tap water flow rate to the mixer 4, where it will mix with the tap water to produce diluted water with the desired chlorine concentration of 50 ppm (the concentration indicator lamp on the mixer will light up). Similarly, if you want diluted water at 100 ppm, you can proportionally control the duty cycle of the DC motor pump by controlling the tap water flow rate between 1.1 (L / min) and 3.0 (L / min), and if you want diluted water at 200 ppm, you can control it between 1.1 (L / min) and 1.7 (L / min).

[0031] [Table 2]

[0032] Table 2 shows the actual chlorine concentration (50 ppm) measured relative to the tap water flow rate using proportional control. The measured values ​​were obtained by turning on a tap water faucet and measuring the flow rate of the electrolyzed hypochlorous acid solution (6120 ppm), and then using proportional control of the pump relative to that flow rate. Although there is some variation, the diluted chlorine concentration is maintained at approximately 50 ppm when the tap water flow rate is between 2.2 (L / min) and 6.8 (L / min).

[0033] Similarly, to produce 100 ppm diluted water, a DC motor is driven at a duty cycle of approximately 30% when the tap water flow rate is 1.1 mL / min, and at a duty cycle of approximately 70% when the tap water flow rate is 3.0 mL / min. This pump 6 sends 16.67 mL / min to 50.01 mL / min of the stock solution (chlorine concentration 6000 ppm) to the mixer 4, where it is mixed with tap water to produce 100 ppm diluted water, which is then discharged from the tap. Furthermore, the 200 ppm dilution water is supplied by driving a DC motor at a duty cycle of approximately 45% when the tap water flow rate is 1.1 mL / min, and at a duty cycle of approximately 70% when the tap water flow rate is 1.7 mL / min. This pump 6 sends the stock solution (chlorine concentration 6000 ppm) at a rate of approximately 33.34 mL / min to 51.53 mL / min to the display unit 4. The display unit 4 then mixes the stock solution with tap water to create the diluted water, and the mixer 4 discharges the diluted water of the same concentration, as indicated by the lamp, from the tap.

[0034] [Table 3]

[0035] Table 3 shows the actual chlorine concentration (200 ppm) measured relative to the tap water flow rate using proportional control. The measured values ​​were obtained by turning on a tap water faucet and measuring the flow rate of the electrolyzed hypochlorous acid solution (6120 ppm), and then using proportional control of the pump relative to that flow rate. Although there is some variation, the diluted chlorine concentration is maintained at approximately 200 ppm when the tap water flow rate is between 1.1 (L / min) and 1.7 (L / min).

[0036] (When diluting, labeling, and dispensing commercially available sodium hypochlorite solution) As described above, we have explained the case in which electrolytically produced hypochlorous acid water (chlorine concentration 6000 ppm) produced by a separately installed electrolytically produced hypochlorous acid water generator is diluted with the dilution display device 1 according to this Example 1. Next, we will explain the case in which a commercially available disinfectant solution (for example, 6% Purelax (registered trademark No. 703738) (chemically a sodium hypochlorite solution), which is approved as a disinfectant for food additives) is put into the stock solution tank 2, diluted to a desired chlorine concentration in the mixer 4 in consideration of the tap water flow rate, and the diluted water of the same chlorine concentration is discharged from the tap while the result is displayed on the mixer 4.

[0037] Commercially available 6% Purelax has a shelf life of one year, and after opening, it can last for one year if stored in a cool, dark place, but it is recommended to use it within six months. Sodium hypochlorite such as 6% Purelax cannot be measured with a chlorine concentration meter unless it is diluted, but in this example, based on the results of a predetermined measurement, the effective chlorine concentration of 6% Purelax has decreased to the equivalent of 54,000 ppm, so we will assume that it is 54,000 ppm and dilute it with the mixer 4 of the dilution display device 1 according to Example 1, and then display and dispense the chlorine concentration of this diluted water. In the dilution display device 1 according to Example 1, in order to perform a predetermined dilution of the 6% Purelax solution based on the amount of tap water, a corresponding chlorine concentration display and a switch for changing the pump drive are provided, and the general flow of the dilution is as follows.

[0038] (Dilution of 6% Purelax solution) In the dilution display device 1 according to this embodiment 1, a DC motor (actually a DC motor) with the specifications shown in Figure 3 described above is driven and controlled to mix and dilute a commercially available 6% Purelax solution based on the tap water flow rate to obtain diluted water with the desired chlorine concentration. In other words, as described above, mixing 1.79 mL / min of 6% Purelax solution with a chlorine concentration of 54,000 ppm with tap water flowing at a flow rate of 1.0 L / min produces 100 ppm dilution water, mixing 3.58 mL / min of 6% Purelax solution with a chlorine concentration of 54,000 ppm with tap water flowing at a flow rate of 1.0 L / min produces 200 ppm dilution water, and mixing 8.95 mL / min of 6% Purelax solution with a chlorine concentration of 54,000 ppm with tap water flowing at a flow rate of 1.0 L / min produces 500 ppm dilution water by controlling the drive of the DC motor.

[0039] In this way, the dilution display device 1 according to this embodiment 1 drives and controls a DC motor based on the water flow rate from a mixer 4 directly connected to a water tap, so that even when 6% Purelax (chlorine concentration 54,000 ppm) is used as the stock solution, it produces diluted water of the desired chlorine concentration (for example, 100 ppm, 200 ppm, 500 ppm), displays the chlorine concentration, and discharges the diluted water from the water tap.

[0040] In the dilution display device 1 according to this embodiment 1, the details of the dilution, display, and dispensing flow of commercially available 6% Purelax in a mixer 4 directly connected to a water tap are as follows. (a) The switch 10 of the repeater selects whether the liquid in the stock tank 2 is 6000 ppm electrolyzed hypochlorous acid water or 60000 ppm sodium hypochlorite. (b) By pressing switch 9, the desired diluted chlorine concentration is displayed on the chlorine concentration display mixer 4. (c) The water tap is turned on and the water flow rate is detected by the mixer 4 which is directly connected to the tap. (d) Based on the detection of tap water flow rate, the relay unit's pump starts drawing the concentrate (6% Purelax) from the concentrate tank. (e) Based on the detected tap water flow rate, the pump is driven at a duty cycle proportional to the chlorine concentration, and the undiluted solution is sent to the mixer 4. (f) Mix the concentrate with tap water in mixer 4 to dilute and dispense the solution. Specifically, 6% Purelax (equivalent to a chlorine concentration of 54,000 ppm) is added to the stock tank 2 of the dilution display device 1 according to this embodiment 1, as shown in Figure 2, and then the aforementioned flow (a) to (f) is carried out.

[0041] Furthermore, when using the dilution display device 1 according to this embodiment 1 to dilute sodium hypochlorite such as 6% Purelax, the chlorine concentration display will not be in the form of a dilution water concentration display for electrolyzed hypochlorous acid water, with 50 ppm lamps, 100 ppm lamps, and 200 ppm lamps. Instead, by turning on switch 9, the lamp display will be changed to a 100 ppm lamp, a 200 ppm lamp, and a 500 ppm lamp. This is because the chlorine concentration of the 6% Purelax being added is 54,000 ppm, which is a higher chlorine concentration compared to electrolyzed hypochlorous acid water, and the concentration display should correspond to this.

[0042] Furthermore, by switching switch 9, the DC motor drive described above is modified to adjust the drainage volume of pump 6 to match the 6% Purelax dilution when diluting 6% Purelax with tap water. As described above, the dilution of the 6% Purelax is the same in that it controls the flow rate of tap water from the mixer 4 directly connected to the water tap and the supply of the undiluted solution from the pump 6, based on the graph showing the correlation between the DC motor and the flow rate (mL / min) of the pump 6 that uses it, as shown in Figure 3, in order to dilute, display, and discharge the solution.

[0043] In other words, in the dilution display device 1 according to this embodiment 1, the flow rate of the pump 6 is controlled in the mixer 4 based on the duty cycle with the value detected by the tap water flow sensor to dilute the 6% Purelax (chlorine concentration 54,000 ppm) with a chlorine concentration of 54,000 ppm, and the chlorine concentration of the discharged diluted water is indicated by lighting up a chlorine concentration indicator lamp (either a 100 ppm lamp, a 200 ppm lamp, or a 500 ppm lamp).

[0044] In the dilution display device 1 according to this embodiment 1, when the water tap is turned on (opened), a lamp that displays the chlorine concentration of the previously discharged dilution water (for example, 100 ppm) lights up, and the built-in flow sensor 8 detects the water flow rate. Based on this detection result, as described above, the DC motor is driven at a duty cycle corresponding to the lamp display, and dilution water with the chlorine concentration displayed on the lamp (for example, 100 ppm) is discharged from the water tap. Then, if the tap is turned on or off while the water is being discharged from the tap, the flow sensor 8 of the mixer 4, which is directly connected to the tap, detects the flow rate of the tap water each time, sends the tap water flow rate value to the relay unit 3, and controls the flow rate of the pump 6 as described above to mix and dilute the water with the tap water, maintaining the chlorine concentration of the discharged diluted water (for example, 100 ppm) and discharging it (a detailed explanation of the 500 ppm display is omitted, but the flow is the same).

[0045] [Table 4]

[0046] Table 4 shows the tap water flow rates corresponding to the concentration of diluted water dispensed after diluting and labeling commercially available 6% Purelax. For example, if set to 500 ppm, the diluted water produced by mixing with tap water inside the mixer will be dispensed at a concentration of 500 ppm at a flow rate of 1.5 to 3.0 L / min. However, flow rates below 1.0 L / min (outside this range) will result in a higher concentration, while flow rates above 3.5 L / min will result in a lower concentration. In Table 4, the "Conventional" column refers to the actual chlorine concentration of the diluted water relative to the tap water flow rate when diluting with a constant pump flow rate without varying the duty cycle of the DC motor. In other words, the tap water flow rate required to stably discharge the diluted water at the desired concentration is 1.5 to 3.0 (L / min) for 500 ppm, 2.5 to 7.0 (L / min) for 200 ppm, and 4.5 to 7.0 (L / min) for 100 ppm. Because there is an upper limit to the pump flow rate, an upper limit to the tap water volume is imposed in order to maintain a constant concentration of the diluted water. Conversely, if the duty cycle of the DC motor is varied and reduced, there is a duty cycle at which the pump can no longer be driven, thus creating a lower limit to the tap water flow rate. (However, this limitation can be eliminated by operating the pump intermittently).

[0047] Furthermore, in accordance with the lamp indicators used in the mixer 203 of the invention related to utility model registration No. 3241138, for example, if the tap water flow rate is 6.0 (L / min) to 7.0 (L / min) and the chlorine concentration is 270.0 ppm to 231.4 ppm, the 200 ppm lamp will be lit alone, and if the tap water flow rate is 3.5 (L / min) to 6.0 (L / min) and the chlorine concentration is 462.9 ppm to 270.0 ppm, the 200 ppm lamp will be lit. The indicator can be set to display both the 500ppm lamp and the 500ppm lamp simultaneously, or to display only the 500ppm lamp if the chlorine concentration is between 648.0ppm and 462.9ppm at a tap water flow rate of 2.5 (L / min) to 3.5 (L / min), or to display both the 500ppm and 1000ppm lamps simultaneously if the chlorine concentration is between 1080.0ppm and 648.0ppm at a tap water flow rate of 1.5 (L / min) to 2.5 (L / min). However, this is not practical because the range of chlorine concentration actually discharged is too wide compared to the values ​​displayed on the lamps. When diluting with 6% Purelax solution, it is better to use a DC motor to vary the duty cycle and discharge the diluted water at a constant concentration.

[0048] (Indicator lamp for 6% Purelax solution dilution) In the dilution display device 1 according to this embodiment 1, the lamp display for the dilution water concentration obtained by diluting 6% Purelax solution is basically the same as the lamp display described above. However, since 6% Purelax solution has a concentration of 54,000 ppm, the chlorine concentration of the diluted water is also displayed with lamps for 100 ppm, 200 ppm, and 500 ppm. By using the switch (concentration selection) labeled 9 on the repeater in Figure 2 to select the concentration of the diluted water, for example, if a chlorine concentration of 100 ppm is selected, the program built into the control board 5 is activated, and the duty cycle of the DC motor is varied according to the flow rate of tap water supplied to the mixer, adjusting the flow rate of the pump supplying 6% Purelax solution (60,000 ppm), and controlling it so that the diluted water has a chlorine concentration of 100 ppm. The tap water flow rate can be controlled in the range of 4.5 to 7.0 (L / min). In the case of a chlorine concentration of 200 ppm, the tap water flow rate can be controlled in the range of 2.5 (L / min) to 7.0 (L / min). With a chlorine concentration of 500 ppm, the water flow rate can be controlled within a range of 1.5 L / min to 3.0 L / min.

[0049] Note that pumps have upper and lower flow rate limits, which can cause them to become inoperable. This can be addressed by changing the pump specifications to use a DC motor. Furthermore, when using a pump of the same capacity, intermittent operation (repeated operation / stopping) reduces the pump's discharge volume to approximately half of that of continuous operation. Duty cycle control ensures that the concentrate is added and supplied at a rate corresponding to the tap water flow rate. This allows the same pump to handle changes in the concentration of the concentrate. Alternatively, a stepping motor or similar device can be used to vary the drive pulse and control the discharge volume, achieving a similar effect. Furthermore, the above explanation described the example of diluting a commercially available 6% sodium hypochlorite solution and displaying the concentration before dispensing it. However, other 6% and 12% solutions of other products used for food hygiene or pharmaceuticals, such as Gianoc (registered trademark No. 1848011) and New Bleach (both sodium hypochlorite solutions), can be used. In such cases, as described above, the pump of the dilution display device 1 according to this embodiment 1 can be appropriately configured, and the duty cycle of the dilution can be changed to accommodate this.

[0050] As described above, by configuring the electrolytically generated hypochlorous acid water or commercially available sodium hypochlorite solution dilution display device 1 according to this embodiment 1 in an appropriate device configuration as described above, and by appropriately executing the dilution duty cycle and control flow, it becomes possible to store pre-generated electrolytically generated hypochlorous acid water or commercially available disinfectant solution (sodium hypochlorite solution) in a raw water tank, dilute the stored pre-generated electrolytically generated hypochlorous acid water or commercially available disinfectant solution to a desired chlorine concentration based on the inflow rate of tap water flowing into the water tap, and discharge the diluted solution from the water tap while displaying its chlorine concentration. Furthermore, by using the diluted discharged water for disinfecting and sterilizing food ingredients, food and beverage containers, equipment, etc., efficient sterilization and disinfection become possible. In addition, since the diluted water has a visually displayed chlorine concentration, sterilization and disinfection can be performed safely.

[0051] As described above, the dilution, display, and discharge of electrolyzed hypochlorous acid water with a chlorine concentration of 6000 ppm and the dilution, display, and discharge of commercially available 6% Purelax with a chlorine concentration of 54000 ppm in the dilution display device 1 of this embodiment 1 have been explained, but it is not limited to the dilution, display, and discharge of electrolyzed hypochlorous acid water with a chlorine concentration of 6000 ppm and the dilution, display, and discharge of commercially available 6% Purelax with a chlorine concentration of 54000 ppm. For example, by controlling the DC motor drive in response to fluctuations in the water volume of the device 1 as shown below, it becomes possible to dilute, display, and dispense diluted water with the desired chlorine concentration.

[0052] In addition, in the lamp display of the dilution display device 1 according to this embodiment 1, if an abnormal condition occurs, such as when the flow rate of tap water goes outside the controllable range, the lamp on the right side of the mixer 4 will flash to visually indicate this, or a warning buzzer will be sounded at the same time.
