Description

  The present invention is a sterilized water production for producing sterilized water by diluting sodium hypochlorite or equivalent electrolytic water with water and mixing dilute hydrochloric acid as an activator. More particularly, the present invention relates to a sterilizing water manufacturing apparatus capable of automatically manufacturing sterilizing water capable of exhibiting an optimum sterilizing power and a sterilizing water manufacturing method using the same.

  As is well known, diluted sodium hypochlorite (hereinafter referred to as “sodium hypochlorite aqueous solution”) is an additive stipulated in the Food Sanitation Law and has a bactericidal effect. Electrolytic functional water obtained by electrolyzing an aqueous solution containing a small amount of sodium chloride is also equivalent to the sodium hypochlorite aqueous solution. This electrolytic functional water is diluted with water and used as an activator. It is known to produce sterilized water having a high sterilizing effect by mixing dilute hydrochloric acid.

  That is, it is known that sterilizing water having a strong sterilizing effect can be obtained by diluting alkaline electrolyzed functional water with water and mixing dilute hydrochloric acid to make the pH strongly 2.7 or less. .

  However, there is a problem that the shelf life is poor when the electrolytically functional water and dilute hydrochloric acid are mixed. Conventionally, when a container containing electrolytically functional water and a container containing dilute hydrochloric acid are separately provided and used, The method of mixing these was used.

  That is, conventionally, when using sterilized water obtained by mixing electrolyzed functional water and dilute hydrochloric acid, an operation of mixing electrolyzed functional water and dilute hydrochloric acid is required each time, and it has not been troublesome.

  In this regard, a sterilizing water manufacturing apparatus that automatically mixes sodium hypochlorite and an activator has been provided, but the conventional sterilizing water manufacturing apparatus is effective. It has been difficult to automatically produce sterilized water having a sterilizing effect.

That is, when diluting an aqueous sodium hypochlorite solution or electrolyzed functional water with water and mixing dilute hydrochloric acid, the mixing ratio of water and dilute hydrochloric acid to the sodium hypochlorite aqueous solution is important, and the optimal mixing ratio must be set. Since effective sterilizing water cannot be produced, the amount of dilution water supplied is constantly monitored, and depending on the amount, dilute hydrochloric acid such as an optimal amount of sodium hypochlorite aqueous solution can be mixed. However, no conventional sterilizing water production apparatus has such a function.

  Therefore, according to the sterilizing water production apparatus of the present invention, the optimum mixing ratio of water, electrolytic functional water diluted with sodium hypochlorite or equivalent thereto, and dilute hydrochloric acid is automatically set. It is possible to achieve this and automatically produce effective sterilizing water.

  The apparatus for producing sterilized water according to the present invention includes a main flow path, and the main flow path includes a water supply port connected to a tap water tap and a water discharge port for discharging the produced sterilized water. .

The first chemical liquid pump and / or the second chemical liquid pump is operated when a water flow having the same value as the detected value is detected, and the main flow path is diluted with sodium hypochlorite or equivalent thereto. Electrolytic functional water and / or dilute hydrochloric acid is mixed, thereby making it possible to produce sterilized water in the main flow path.

  Here, an infrared sensor is used as each of the first and second chemical liquid sensors, and the infrared sensor may be mounted in an oblique direction with respect to the sodium hypochlorite mixed flow path or the dilute hydrochloric acid mixed flow path.

It may be connected downstream of the connection point with the means, so that even when the tap water pressure is high, it is possible to mix sodium hypochlorite aqueous solution and dilute hydrochloric acid into tap water at an optimal ratio.

  The first embodiment of the sterilizing water production apparatus of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the sterilizing water production apparatus of the first embodiment. The manufacturing apparatus dilutes the above-mentioned electrolytic functional water (hereinafter referred to as “sodium hypochlorite aqueous solution”) equivalent to an aqueous sodium hypochlorite solution or equivalent with tap water, and further dilutes with this tap water. A device for producing sterilized water by mixing dilute hydrochloric acid into the aqueous sodium hypochlorite aqueous solution or the like.

  That is, in the figure, 1 is the sterilizing water production apparatus of the first embodiment, and the sterilizing water production apparatus 1 of the first embodiment has a main flow path 2 for producing sterilizing water therein. And this main flow path 2 has the water supply port 201 connected with the faucet of a water supply in the front-end | tip, and has the water discharge port 202 which discharges the sterilized water manufactured at the terminal, and is used as dilution water from the said water supply port 201. After the tap water is received and sterilized water is produced in the main channel 2, the water can be discharged from the outlet 202. In the figure, reference numeral 203 denotes a free bellows provided around the main flow path 2 in the vicinity of the water discharge port 202. The material of the main channel 2 is not particularly limited, and any material such as a flexible material hose or metal may be used.

  Next, sodium hypochlorite mixing means for mixing a sodium hypochlorite aqueous solution or the like into the tap water flowing in the main channel 2 is connected to the main channel 2.

  That is, in the figure, reference numeral 3 denotes sodium hypochlorite mixing means. In the first embodiment, this sodium hypochlorite mixing means 3 is a sodium hypochlorite mixed flow whose base end portion communicates with the main flow path 2. It has a channel 301, and the tip of the sodium hypochlorite mixed flow channel 301 is located in a sodium hypochlorite container 302 in which a sodium hypochlorite aqueous solution and the like are stored. In addition, the form of the sodium hypochlorite container 302 is not particularly limited, and any type may be used as long as it can store sodium hypochlorite inside, such as a tank type and a bottle type.

  Next, a unimol pump 303 as a first chemical liquid pump is interposed in the sodium hypochlorite mixed flow path 301. By operating the first chemical liquid pump 303, the sodium hypochlorite container 302 contains The sodium hypochlorite aqueous solution or the like can be mixed into the tap water flowing through the main flow path 2, and the amount of the sodium hypochlorite aqueous solution or the like mixed into the tap water can be adjusted.

  Further, a first chemical liquid sensor 304 is provided between the first chemical liquid pump 303 and the main flow path 2, and sodium hypochlorite is introduced into the main flow path 2 by the first chemical liquid sensor 304. Whether or not an aqueous solution or the like is mixed, that is, the presence or absence of an aqueous sodium hypochlorite solution in the sodium hypochlorite container 302 can be detected.

  Here, in the first embodiment, the first chemical sensor 304 uses an infrared sensor, and this infrared sensor is mounted obliquely with respect to the axial direction of the sodium hypochlorite mixed flow channel 301. Yes. As a result, the sodium hypochlorite aqueous solution and the like flowing through the sodium hypochlorite mixed flow channel 301 can be reliably detected.

  That is, when the first chemical sensor 304 is disposed perpendicular to the axial direction of the sodium hypochlorite mixed flow channel 301, an aqueous sodium hypochlorite solution or the like passes through the sodium hypochlorite mixed flow channel 301. In either case of flowing or not flowing, infrared rays pass through the sodium hypochlorite mixed flow channel 301, so that a sodium hypochlorite aqueous solution or the like is mixed with the sodium hypochlorite mixed flow channel 301. It is not possible to distinguish between the case of flowing inside and the case of not flowing. That is, the presence or absence of the sodium hypochlorite aqueous solution in the sodium hypochlorite container 302 cannot be detected.

  However, when the first chemical solution sensor 304 is mounted obliquely with respect to the axial direction of the sodium hypochlorite mixed flow channel 301, the sodium hypochlorite aqueous solution or the like passes through the sodium hypochlorite mixed flow channel 301. In this case, since the infrared rays are refracted in the sodium hypochlorite mixed flow channel 301, the infrared light cannot be received by the light receiving portion of the first chemical liquid sensor 304, and thereby the sodium hypochlorite mixed flow channel 301. The presence or absence of a sodium hypochlorite aqueous solution or the like can be reliably detected. Accordingly, in the first embodiment, it is reliably detected whether or not the sodium hypochlorite aqueous solution is mixed in the main flow path 2. can do.

  Next, reference numeral 4 in the figure denotes dilute hydrochloric acid mixing means for mixing dilute hydrochloric acid as an activator into the main flow path 2. That is, in the sterilizing water production apparatus of the first embodiment, the dilute hydrochloric acid mixing means 4 is connected to the downstream side of the main passage 2 with respect to the connecting portion of the sodium hypochlorite mixing means 3, so that tap water is used. Diluted hydrochloric acid as an activator can be mixed in a sodium hypochlorite aqueous solution or the like flowing through the main flow path 2 while being diluted.

  Here, the dilute hydrochloric acid mixing means 4 will be described. In the first embodiment, the dilute hydrochloric acid mixing means 4 has a dilute hydrochloric acid mixing channel 401 in the same manner as the sodium hypochlorite mixing means 3, and this dilute hydrochloric acid mixing means. The flow path 401 has a distal end located in a dilute hydrochloric acid container 402 in which dilute hydrochloric acid is stored, and a base end communicates with the main flow path 2. As in the case of the sodium hypochlorite container 302, the form of the dilute hydrochloric acid container 402 is not particularly limited as long as it can store dilute hydrochloric acid inside, such as a tank type or a bottle type. Good.

  Next, a unimol pump 403 as a second chemical liquid pump is interposed in the dilute hydrochloric acid mixed flow path 401, and by operating the second chemical liquid pump 403, dilute hydrochloric acid in the dilute hydrochloric acid container 402 is converted into the main flow path 2. Thus, sterilized water can be produced by mixing dilute hydrochloric acid with a sodium hypochlorite aqueous solution or the like diluted with tap water, and the amount of dilute hydrochloric acid mixed can be adjusted.

  Further, a second chemical sensor 404 is provided between the connecting portions of the second chemical pump 403 and the main flow path 2, and dilute hydrochloric acid is mixed into the main flow path 2 by the second chemical sensor 404. It is possible to detect whether or not.

  In the first embodiment, the second chemical sensor 404 uses an infrared sensor as in the case of the first chemical sensor 304, and the infrared sensor is oriented obliquely with respect to the axial direction of the dilute hydrochloric acid mixed channel 401. As a result, the dilute hydrochloric acid flowing through the dilute hydrochloric acid mixed channel 401 can be reliably detected, but the operation and the like are the same as in the case of the first chemical sensor 304 described above, and therefore a duplicate description is omitted. To do.

  Next, in the figure, 5 is a water amount valve. That is, in the first embodiment, the main flow path 2 is equipped with a water amount valve 5 on the upstream side of the sodium hypochlorite mixing means 3, and by operating the water amount valve 5, the main flow path The amount of tap water supplied in 2 can be adjusted.

  An electromagnetic valve is provided between the water amount valve 5 and the sodium hypochlorite mixing means 3 in the main flow path 2. That is, in the figure, 6 is an electromagnetic valve, and this electromagnetic valve 6 is installed in the main flow path 2 on the downstream side of the installation location of the water amount valve 5, thereby opening the electromagnetic valve 6. Thus, tap water can be supplied into the main flow path 2.

  Further, in the first embodiment, a water flow detection means 7 is provided between the electromagnetic valve 6 and the sodium hypochlorite mixing means 3 in the main flow path 2. It is possible to detect whether or not tap water is flowing and the flow rate when it is flowing.

  Here, the water flow detection means 7 will be described. In the first embodiment, the water flow detection means 7 is composed of a flow indicator 702 and a water flow sensor 701, and the water flow sensor 701 uses an infrared sensor 701. The flow indicator 702 is attached in such an arrangement that the wings of the flow indicator 702 are rotated by tap water flowing in the main flow path 2, and the infrared sensor is connected between the light emitting part and the light receiving part. It is installed in such an arrangement. In other words, the infrared rays emitted from the light emitting part of the infrared sensor can be cut off depending on the position of the wings, thereby detecting the flow of tap water supplied into the main flow path 2.

  That is, when tap water is supplied into the main flow path 2, the wings of the flow indicator 702 rotate, so that the wings pass between the light emitting part and the light receiving part of the infrared sensor and block the passage of infrared rays. The water flow sensor 701 is turned off. Therefore, this makes it possible to take out a pulse signal corresponding to the number of rotations of the wings, and to know the flow of tap water flowing in the main flow path 2.

  In the figure, 9 is a drain valve. That is, in the first embodiment, in the main channel 2, a drainage channel 8 is branched between the water flow detection means 7 and the sodium hypochlorite mixing unit 3, and a drainage valve 9 is provided in the drainage channel 8. Thereby, drainage of tap water in the main flow path 2 is enabled.

  Next, the control system of the sterilizing water production apparatus according to the first embodiment will be described with reference to FIG. 5. In the sterilizing water production apparatus 1 according to the first embodiment, control of a microcomputer or the like for controlling the operation of the entire apparatus. The control unit includes an electromagnetic sensor 6, an infrared sensor as the water flow sensor 701, an infrared sensor as the first chemical sensor 304, an infrared sensor as the first chemical pump 303, and an infrared sensor as the second chemical sensor 404. In addition to a sensor, a second chemical pump 403, a buzzer as an informing means, an LED, and a monitor, a power source, an operation switch, and the like are connected.

  Then, the control unit opens the electromagnetic valve 6 by switching on, operates the first and second chemical pumps 303 and 403 based on the detection signal from the water flow detection means 7, and also controls the first and first The operation of the electromagnetic valve 6 is controlled based on detection signals from the two chemical liquid sensors 304 and 404.

  Next, the sterilizing water manufacturing method using the sterilizing water manufacturing apparatus 1 of the first embodiment configured as described above will be described in detail with reference to the flowchart of FIG. When sterilizing water is produced by the apparatus 1, a sodium hypochlorite aqueous solution or the like is previously stored in the sodium hypochlorite container 302, dilute hydrochloric acid is stored in the dilute hydrochloric acid container 402, and the water amount valve 5 is adjusted. After adjusting the amount of tap water supplied into the main channel 2, the water supply port 201 is connected to a tap faucet opened.

  Further, the mixing ratio of sodium hypochlorite aqueous solution and dilute hydrochloric acid to tap water is set and stored in the control unit using an operation switch or the like. In the first embodiment, the sodium hypochlorite aqueous solution and the like stored in the sodium hypochlorite container 302 is 2,000 ppm, and the final sterilized water is 20 ppm and has a pH of 2.7 or less. Was set as follows. That is, the aqueous solution of sodium hypochlorite and dilute hydrochloric acid were mixed according to the flow rate of tap water so that the sterilizing water discharged from the water discharge port 202 would be 20 ppm and pH 2.7 or less.

  Next, when the switch is turned on (S1), the electromagnetic valve 6 is opened (S2), and at the same time, the water flow detecting means 7 detects the water flow of the tap water flowing in the main flow path 2 (S3). The switch is not particularly limited, and a manual switch, a foot switch, a proximity sensor, or the like may be used.

  When the water flow detection result by the water flow detection means 7 indicates that the water flow of the tap water supplied into the main flow path 2 is not equal to a preset value, a buzzer is sounded (S4), and the water volume adjustment by the water volume valve 5 ( S5) is urged, and the buzzer is continuously sounded until the water flow becomes equal to the preset value by adjusting the water amount. When the tap water flow reaches the preset value, the buzzer is stopped, Step 6 and subsequent steps are executed.

  That is, as a result of water flow detection by the water flow detection means 7, when the water flow of tap water supplied into the main flow path 2 is equal to a preset value, the first and second chemical pumps 303 and 403 are operated, Thereby, tap water flowing in the main flow path 2 is mixed with an appropriate amount of sodium hypochlorite aqueous solution and dilute hydrochloric acid (chemical solution supply) to produce sterilized water (S6).

  Further, in the sterilizing water production in S6, the water flow detection by the water flow detecting means 7 is continued, and the first and second chemical liquid sensors 304 and 404 are surely mixed with sodium hypochlorite aqueous solution and dilute hydrochloric acid. Detect whether or not.

  And while the water flow of the tap water supplied in the main flow path 2 is equivalent to the preset value, while a sodium hypochlorite aqueous solution or dilute hydrochloric acid is mixed in the main flow path 2, the chemical solution supply of S6 is performed. On the other hand, if the water flow of tap water supplied into the main flow path 2 is not equal to a preset value due to some cause such as a decrease in tap water pressure, or hypochlorous acid When mixing of sodium aqueous solution or the like or dilute hydrochloric acid into the main flow path 2 cannot be detected, for example, when the sodium hypochlorite aqueous solution in the sodium hypochlorite container 302 or the dilute hydrochloric acid in the dilute hydrochloric acid container 402 disappears, The electromagnetic valve 6 is closed and the notification means such as LED lighting is operated (S7).

  Further, in the sterilizing water production apparatus 1 of the first embodiment, when the sodium hypochlorite container 302 or the dilute hydrochloric acid container 402 is replaced with a new container, the first or second chemical liquid sensor 304, 404 is replaced with hypochlorous acid. Only the first or second chemical pumps 303 and 403 are operated until it is detected that sodium aqueous solution or the like or dilute hydrochloric acid is mixed into the main flow path 2.

  That is, when the sodium hypochlorite container 302 or the diluted hydrochloric acid container 402 is replaced with a new container, air may be contained in the sodium hypochlorite mixed flow path 301 or the diluted hydrochloric acid mixed flow path 401. In this state, if the electromagnetic valve 6 is opened and the first and second chemical pumps 303 and 403 are operated, air is initially mixed into the tap water. Therefore, in the sterilizing water production apparatus 1 of the first embodiment, when the chemical solution container 302 or the like is replaced with a new chemical solution container, the first or second chemical solution sensor 304 or 404 is made of an aqueous sodium hypochlorite solution or the like or dilute hydrochloric acid. Until the mixing into the main flow path 2 is detected, only the first or second chemical pumps 303 and 403 are operated.

  In addition, in 1st Example, it is set as the structure which connects the water supply port 201 to the tap of water supply, and stirs tap water, sodium hypochlorite, and dilute hydrochloric acid in the main flow path 2 using the water pressure of tap water. It is said.

  Thus, in the first embodiment, when the water flow detecting means detects a water flow having the same value as the preset value, a sodium hypochlorite aqueous solution and dilute hydrochloric acid are mixed in the main flow path, In this state, the sterilizing water is manufactured using the water pressure of the tap water, and when the first chemical solution sensor or the second chemical solution sensor does not detect the supply of the chemical solution in this state, the electromagnetic valve is closed. While preventing the production of sterilizing water with a small proportion of dilution water, it is also possible to prevent the production of sterilizing water with a too high proportion of dilution water.

  Therefore, according to the first embodiment, the optimum mixing ratio of water, sodium hypochlorite and dilute hydrochloric acid can be automatically achieved, and effective sterilized water can be automatically produced. is there.

  In the above description, the case where sodium hypochlorite aqueous solution or the like and dilute hydrochloric acid are mixed into the tap water in the main flow path 2 to produce sterilizing water is described. However, only sodium hypochlorite is used in the main flow path. 2 may be mixed into the washing water to produce the washing water.

  Further, the water flow detection means 7 is not necessarily limited to the above-described configuration, and any means may be used as long as it is a means capable of detecting the water pressure of tap water flowing in the main flow path 2.

  Furthermore, the notification means when the sodium hypochlorite aqueous solution in the sodium hypochlorite container 302 or the dilute hydrochloric acid container 402 or the dilute hydrochloric acid is lost is not necessarily limited to the lighting of the LED, and the container is empty. Any method can be used as long as it can inform the user of this fact. Therefore, a buzzer may be sounded, or a monitor may be provided to display a warning on the monitor screen.

  Next, a second embodiment of the sterilizing water production apparatus of the present invention will be described with reference to FIG. 2. FIG. 2 is a block diagram showing the configuration of the sterilizing water production apparatus of the second embodiment. Is the sterilizing water production apparatus of the second embodiment.

  That is, in the sterilizing water production apparatus 11 of the second embodiment, the main flow path 2 is upstream of the location where the sodium hypochlorite mixing means 3 is connected, and the sodium hypochlorite supply path 10a and the dilute hydrochloric acid supply path. It branches into two 10b.

  The sodium hypochlorite supply path 10a is connected to the sodium hypochlorite mixing means 3, while the dilute hydrochloric acid supply path 10b is connected to the dilute hydrochloric acid mixing means 4, and this hypochlorite is further connected. The sodium acid supply path 10a and the dilute hydrochloric acid supply path 10b are merged in the combined flow path 11 formed before the water discharge port 202, so that toxic gas is generated by mixing the sodium hypochlorite aqueous solution and the dilute hydrochloric acid. It is preventing.

  That is, it is considered that toxic gas is generated when dilute hydrochloric acid is mixed in the tap water before the sodium hypochlorite aqueous solution is sufficiently diluted with the tap water. . Therefore, in the second embodiment, the main flow path 2 is branched into two, a sodium hypochlorite supply path 10a and a dilute hydrochloric acid supply path 10b, and a sodium hypochlorite aqueous solution and dilute hydrochloric acid are mixed in each of the branch paths 10a and 10b. Then, the aqueous sodium hypochlorite solution and dilute hydrochloric acid are mixed in the combined channel 11 after being sufficiently diluted with tap water.

  In the sterilizing water production apparatus 11 of the second embodiment, the main flow path 2 is branched into two, a sodium hypochlorite supply path 10a and a dilute hydrochloric acid supply path 10b, and the sodium hypochlorite supply path 10a has a hypoxia. The sodium chlorate mixing means 3 is connected, the diluted hydrochloric acid supply path 10b is connected to the diluted hydrochloric acid mixing means 4, and the sodium hypochlorite supply path 10a and the diluted hydrochloric acid supply path 10b are formed in front of the water outlet 202. 11, and the other configurations and functions are the same as those of the first embodiment described above, and thus the same parts are denoted by the same reference numerals and redundant description is omitted.

  Next, a third embodiment of the sterilizing water production apparatus of the present invention will be described with reference to FIG. 3. FIG. 3 is a block diagram showing the configuration of the sterilizing water production apparatus of the third embodiment. Is the sterilizing water production apparatus of the present embodiment.

  The sterilizing water production apparatus 21 of the third embodiment is characterized in that, in the sterilizing water production apparatus of the first embodiment described above, the main flow path 2 is branched to form a branch path.

  That is, 12 is a branch path in the figure, and in the third embodiment, the main flow path 2 is branched upstream of the connection location of the sodium hypochlorite mixing means 3 to form the branch path 12. The branch path 12 is joined to the main flow path 2 downstream of the connecting portion of the dilute hydrochloric acid mixing means 4. Thus, when the water pressure of the tap water is high, the mixing ratio of sodium hypochlorite and dilute hydrochloric acid to the tap water is prevented from becoming lower than a preset ratio.

  In other words, when the water pressure of tap water is high, it may be considered that the sodium hypochlorite aqueous solution and dilute hydrochloric acid cannot be sufficiently supplied to the main flow path 2 even with the chemical pumps 303 and 403. Therefore, in the third embodiment, the main flow path 2 is branched upstream of the connecting portion of the sodium hypochlorite mixing means 3 to weaken the water pressure of the tap water flowing through the main flow path 2, A set amount of sodium hypochlorite aqueous solution and dilute hydrochloric acid can be supplied to the main flow path 2.

  The sterilizing water production apparatus 21 according to the third embodiment is characterized in that the main flow path 2 is branched to form the branch path 12, and the other configuration, operation, and the like are the same as in the first embodiment. Therefore, the same parts are denoted by the same reference numerals, and redundant description is omitted.

FIG. 4 is a block diagram showing the configuration of the sterilizing water production apparatus of the fourth embodiment. Is the sterilizing water production apparatus of the present embodiment.

  The sterilizing water production apparatus 31 of the fourth embodiment is characterized in that, in the sterilizing water production apparatus of the above-described second embodiment, the main flow path 2 is branched to form a branch path.

  That is, in the figure, 12 is a branch path, and in the fourth embodiment, the main flow path 2 is branched upstream of the location where the main flow path 2 is branched into the sodium hypochlorite supply path 10a and the dilute hydrochloric acid supply path 10b. Thus, a branch path 12 is formed, and this branch path 12 merges with the main channel 2 downstream of the merge channel 11. Then, as in the case of the third embodiment described above, when the tap water pressure is high, the mixing ratio of sodium hypochlorite and dilute hydrochloric acid to the tap water is lower than the preset ratio. To prevent that.

  The sterilizing water production apparatus 31 of the fourth embodiment is characterized in that the main flow path 2 is branched and the branch path 12 is formed, and other configurations and operations are the same as those in the second and third embodiments described above. Since it is the same as that of an example, it attaches | subjects the same code | symbol to the same part, and abbreviate | omits the overlapping description.

  In the present invention, when two or more kinds of liquids are mixed to produce sterilized water, it is possible to automatically produce effective sterilized water as an optimum mixing ratio can be achieved automatically. The present invention is applicable to all devices that produce sterilized water by mixing two or more liquids.
