  In the above-described conventional enzyme water generator, the enzyme preparation mixed with water is maintained at an appropriate temperature for a predetermined time, so that the enzyme water can be effectively decomposed to remove dirt such as fats and oils generated at the kitchen site. ing. However, the enzyme preparation used to produce this enzyme water is a biochemical substance or a mixture of microorganisms or both, and such enzyme preparation has a quality that produces its cleaning chemical characteristics from the point of manufacture. Has been found to deteriorate over time. In particular, it is considered that the deterioration over time is accelerated when the storage at the manufacturer side where the strict storage conditions are prepared is shifted to the storage in the enzyme water generator installed at the kitchen site. Therefore, in the enzyme water generator installed in the kitchen site where the amount of enzyme water used is small, the period until the enzyme preparation stored in the enzyme preparation storage container is used up becomes longer, and the time from the replacement of the enzyme preparation storage container becomes longer. As the time passes, the enzyme water whose cleaning chemical quality is lowered is used. In order to avoid degradation of the quality of the enzyme water due to such deterioration of the enzyme preparation over time, it is uneconomical to set an expiration date and replace it with a new one after the expiration date. It is not preferable.

  In view of the above situation, an object of the present invention is to provide an enzyme water generating apparatus capable of generating enzyme water whose cleaning chemical quality does not substantially change in spite of aging degradation of the enzyme preparation. .

  In order to solve the above problems, the present invention generates enzyme water by supplying a predetermined amount of water to the production tank and supplying an appropriate amount according to a predetermined mixing ratio of the enzyme preparation from the enzyme preparation storage container and controlling the temperature. The enzyme water generation apparatus according to the invention includes an apparatus control module for generating enzyme water by controlling various devices based on a production schedule that regulates the production amount of the enzyme water, and an enzyme preparation contained in the enzyme preparation storage container.

  In this configuration, the quality assessment value of the enzyme preparation used on the day is calculated from the degree of quality degradation based on the quality change over time of the enzyme preparation that can be assessed in advance experimentally and empirically. Based on the quality evaluation value, a mixing rate, which is a ratio of the enzyme preparation to water in the enzyme water generation process on the day, is determined, and enzyme water is generated using the determined mixing rate. In other words, the higher the quality degradation degree of the enzyme preparation used, the larger the mixing ratio and the more the amount of the enzyme preparation for the same amount of water, the cleaning chemical of the resulting enzyme water Quality is maintained. This is the inventor of the present application that enzyme water having sufficient cleaning chemical quality can be obtained by adjusting the mixing rate in the enzyme water generation treatment using this enzyme preparation even if the quality of the enzyme preparation deteriorates. Based on the knowledge of.

  When calculating the quality evaluation value based on the degree of deterioration over time, if only the date of manufacture of the enzyme preparation is used as a reference, storage in a dedicated storage device on the manufacturer side or user side where the strict storage conditions are in place and the kitchen site The difference in the degree of progress of deterioration with time during storage under adverse conditions in the case is ignored. Therefore, in one preferred embodiment of the present invention, the quality evaluation unit calculates the quality evaluation value according to the date of manufacture of the enzyme preparation and the period from the start date of use of the enzyme preparation. It is configured. As a result, a more accurate quality degradation level, that is, a quality evaluation value is calculated by considering the difference in the degree of deterioration over time between storage at the manufacturer side and storage at the kitchen site. Proper enzyme water is produced. In addition, data such as the date of manufacture and start of use, which are important attribute values of the enzyme preparation used, can be obtained reliably and easily and set inside the enzyme water generator to calculate the quality evaluation value of the enzyme preparation. In order to utilize, in one of the preferred embodiments of the present invention, the enzyme preparation storage container is configured as a replaceable container provided with an attribute code that records the attribute value of the enzyme preparation contained in the container. The quality evaluation unit is configured to calculate a quality evaluation value from read data from a code reader that reads the attribute code.

As described above, in the enzyme water generating apparatus according to the present invention, it is possible that the remaining amount of the enzyme preparation storage container may be lost without knowing that the enzyme preparation storage container is not prepared. Water cannot be generated. Therefore, in one of the more preferred embodiments of the present invention, the enzyme preparation management module includes a remaining amount calculation unit that calculates the remaining amount of the enzyme preparation in the enzyme preparation storage container, and the remaining amount calculation unit The replacement time of the enzyme preparation storage container is estimated from the remaining amount calculated by the above, and the replacement time is notified through a notification means. In this configuration, the remaining amount of the enzyme preparation stored in the enzyme preparation storage container is calculated based on the daily required amount of enzyme water and the amount of the enzyme preparation determined by the mixing ratio, and is estimated from this calculated remaining amount. Since the renewal time of the enzyme preparation is notified through the notification means as necessary, the replacement and purchase of the enzyme preparation storage container can be performed at an appropriate time.

An evaluation unit 66c is provided. The remaining amount calculation unit 66a is supplied from the bottle 8 to the production tank T because the amount of the enzyme preparation contained in the updated bottle (for example, a new bottle or a refilled bottle) 8 is set in advance. The remaining amount in the bottle 8 can be determined from the actual accumulated usage up to that day. Then, the update time estimation unit 66b estimates the time when the bottle 8 is emptied and updated with a new product from the remaining amount calculated by the remaining amount calculation unit 66a and the planned generation amount that can be calculated from the generation schedule. Since the update time estimated by the update time estimation unit 66b is notified via the liquid crystal display 56 as an example of the notification means HS, the person in charge can always grasp the update time of the bottle 8. The update time estimated by the update time estimation unit 66b uses the scheduled generation amount after the current day as an estimation parameter. Therefore, if the generation schedule is changed, the update time is reset using the changed generation schedule. Calculated.

  The quality evaluation unit 66c determines the date of manufacture of the enzyme preparation obtained from the read data for the attribute code 81 of the bottle 8 sent from the code reader 82 and the date of attachment of the bottle 8 to the enzyme water generator.

At that time, in the storage period from the date of manufacture of the enzyme preparation, which is considered to be in a good storage state while being sealed, to the start date of use of the enzyme preparation, for example, the quality evaluation value does not change or 6 months to 1 In the storage period from the start date of use of the enzyme preparation that is considered to be in a good storage state as the quality evaluation value is lowered by one rank on the basis of a long period such as about a year, for example, 1 month It is preferable that the quality evaluation value is lowered by one rank every time the reference period elapses with a short period as a reference. In any case, the quality evaluation value indicating the degree of deterioration over time of the enzyme preparation contained in such a bottle 8 can be calculated based on the above-mentioned rules obtained empirically and experimentally. it can.

  The production schedule created by the production schedule management module 63 and the enzyme preparation attribute data created by the enzyme preparation management module 66 are stored in a table in the database unit 64, preferably in a relational data table. An example of the data structure of data stored in the database unit 64 is shown in FIG.

  The calendar table 64A includes dates (date data), days of the week, holidays, holidays, and events as data items. Dates, days of the week, and holidays are set in advance, but closed days (regular holidays) are set as specific values for the kitchen site (restaurants, etc.) that use this enzyme water generator, and the event is also the area of this kitchen site. It is set as a specific value (event such as a festival).

  In the schedule table 64B, the date linked to the date in the calendar table 64A, the amount of enzyme water produced for the day specified by the date, the mixing ratio, the kitchen cleaning start time (usually considered as restaurant closing time) However, a certain enzyme water request time, an enzyme preparation ID that can be replaced with the ID of the attached bottle 8, and the like are included as data items. The amount of enzyme water produced and the start time of kitchen cleaning are individually set as values specific to the kitchen site. As described above, the daily mixing ratio (the mixing ratio on the day) specified in the schedule table 64B is determined using the quality evaluation value of the enzyme preparation used calculated by the quality evaluation section 66c of the enzyme preparation management module 66. The mixing ratio is determined by the part 63c. When the mixture ratio is determined to be determined by the mixture ratio determining unit 63c on the day of use each time, the data item of the mixture ratio is naturally omitted from the schedule table 64B.

  In the enzyme preparation table 64C, the enzyme preparation ID linked to the enzyme preparation ID of the schedule table 64B, the use start date which is also the date attached to the enzyme generating device, and the remaining amount of the enzyme preparation calculated by the remaining amount calculation unit 66a. The data items include the amount, the date of manufacture of the enzyme preparation that can be obtained from the read data of the code reader 82, the reference mixing rate set for the enzyme preparation, and the like. At the time when the bottle 8 is attached to the enzyme generation device, the remaining amount of the enzyme preparation becomes the content of the new bottle 8.

  In the schedule table 64B, a generation schedule for the next year (not limited to one year) can be registered. In order to simplify the registration and correction of the generation schedule over a long period as described above, a procedure for registration / correction described below is incorporated in the schedule management module 63.

  In the registration procedure shown in FIG. 6, a one-week sub-schedule that is a generation schedule for one week in which the amount of enzyme water generated for each day of the week is set is created based on user input. A generation schedule for each year is automatically created and assigned to the database unit 64 by assigning it to the weeks constituting the year.

  In other words, when the generation schedule registration is selected from the menu, the screen shown in FIG. 7A is displayed on the liquid crystal display 56. Therefore, by operating the setting button 57, a closed day or a business day is set for each day of the week. Assign (# 10). Subsequently, the generation amount on a specific day of the week from Monday to Sunday is input through the screen shown in FIG. 7B (# 11). When the input is not the first time, it is convenient to display the generation amount input last time in advance. Next, the enzyme water request time indicating the time when the generated enzyme water is requested on a specific day of the week is input through the screen shown in FIG. 7C (# 12). Also here, if it is not the first time input, it is convenient to display in advance the enzyme water request time input last time. The input in steps # 11 to # 12 is performed for all days from Monday to Sunday (# 14). When the input for all days of the week is completed, the generation schedule for one week set here is assigned to all the weeks constituting the year, and the generation schedule for each year is created and registered in the database unit 64 (# 15).

  When the generation schedule correction is selected from the menu in order to correct the annual generation schedule registered in this way, a date input search screen shown in FIG. 8A is displayed. When a date is input on this date input search screen, the database section 64 is accessed and the generation schedule for that date is displayed. At this time, if the date to be searched is a business day, as shown in FIG. 8 (b), the production amount registered with the date, the enzyme water request time, and the mixing level (mixing rate) are displayed. Therefore, it can be corrected to a desired value. If the search target date is a closed day, as shown in (c) of FIG. 8, all data is “?” (May be blank), and this date is registered as a closed day. You can understand what was happening. When a non-business day is a business day, if all data is input here, this date is rewritten as a business day. Conversely, in order to make a business day a closed day, a specific symbol such as “0” or “?” May be input to each data. In any case, since these operations change the registered contents, at the time of the change, for example, a lamp display or a buzzer sound, and further blinking of display characters on the liquid crystal display 56 are performed using some notification means. It is informed that the registered content is corrected by a warning display or the like.

  In this enzyme water generating apparatus, pretreatment (water supply control and mixing control) comprising a water supply step (water supply control and mixing control) and an enzyme supply step, the temperature of the mixed liquid of water and the enzyme preparation is raised to a predetermined temperature and the predetermined A predetermined amount of production is ensured by executing the enzyme water generation process consisting of the main process (heat retention control) consisting of a heat retention step that retains the temperature for a predetermined time and the discharge process (discharge control) consisting of the discharge step. Is done. Therefore, the device control module 65 controls the pretreatment control unit 65a for controlling the water supply electromagnetic valve 22 and the electric motor 34, the main process control unit 65b for controlling the heater 16 and the like, and the discharge electromagnetic valve for controlling the discharge electromagnetic valve. A control unit 65c is provided.

  Depending on the day of the week, the number of repetitions of the enzyme water generation process varies depending on the amount of enzyme water generated, and as a result, the total enzyme water generation time also changes. The time is calculated, and at the generation start time, the device control module 65 must control each device to start the enzyme water generation process. Therefore, the generation process monitoring module 67 performs the enzyme water generation process on the device control module 65 based on the enzyme water generation start time calculated from the enzyme water request time read from the generation schedule stored in the database unit 64. Is provided with a wake-up portion 67a that is operated to start the operation. Instead of calculating the enzyme water production start time from the read enzyme water request time every day, the enzyme water production start time is calculated from the input generation amount and the enzyme water request time, and the data item of the production schedule table 64B You may register as one of these. Moreover, you may comprise so that an enzyme water production | generation start time may be input at the time of registration of a production | generation schedule. In any case, the wake-up unit 67a may obtain the enzyme water generation start time so that the device control module 65 can be activated in a timely manner.

  Furthermore, the generation process monitoring module 67 also includes an error processing unit 67b having a function of performing a process for notifying an error that occurs in a series of enzyme water generation processes and a recovery process for the error.

An example of the enzyme water generation process of the day in this enzyme water generator is shown in the flowchart of FIG.
First, the production schedule of the day is read by the initial setting process (# 00), and the production amount, the mixing level (mixing rate), and the enzyme water production start time are acquired. The wakeup unit 67a monitors whether or not the acquired enzyme water production start time has been reached (# 01), and when the enzyme water production start time is reached (# 01 Yes branch), the enzyme water production process starts. It should be noted that until the enzymatic water production start time is reached (# 01 No branch), it is checked whether the production schedule has been changed by correcting the production amount and the enzymatic water request time (# 01a). If the generation schedule is not changed (# 01aNo branch), the process returns to step # 01. If the generation schedule is changed and set (# 01aYes branch), the process returns to step # 00 and the initial setting process is executed again.

  First, in water supply control, the water supply electromagnetic valve 22 is opened to start water supply, and when the liquid level sensor 15 reaches the detection state, the water supply electromagnetic valve 22 is closed to stop water supply (#). 02).

  Next, in the mixing control, the constant volume pump KP is operated by the driving force of the electric motor 34 so that the enzyme preparation stored in the bottle 8 is sucked by the suction tube 25 and generated from the supply tube 26 through the nozzle 27. Supply in the form of dripping into the tank T (step # 03). At the time of the supply, the enzyme preparation supply amount is obtained from the generation amount read from the generation schedule and the mixing rate, and the operation sensor 37 counts the number of operations of the constant volume pump KP so that the enzyme preparation supply amount is obtained. While supplying the enzyme preparation, a mixture of the enzyme preparation and water having an appropriate mixing ratio can be obtained.

  In the heat retention control, electric power is supplied to the heater 16, the temperature of the solution stored in the generation tank T is measured and fed back by the temperature sensor 17, and the temperature of the solution stored in the generation tank T is set to a target temperature region ( By maintaining the temperature at about 40 ° C., control for generating enzyme water in the generation tank T is executed (# 04).

  When it is determined that the set time has elapsed for maintaining the temperature by this heat retention control (# 04) (time-up is determined), the heat retention control is stopped, and the discharge electromagnetic valve 39 is opened, thereby generating tank Discharge control is performed in which the enzyme water generated in T is sent from the discharge pipe 38 to the discharge hose 7 and discharged to the stock tank B (# 05, # 06). In this discharge control, control for setting the discharge electromagnetic valve 39 to the open state for a time sufficient for discharging the enzyme water from the production tank T is executed.

  In addition, the processes in steps # 02, # 03, # 04, and # 06 are pre-processing for generating enzyme water (consisting of a water supply step and a temperature raising / enzyme supply step), a main process consisting of a heat retention step, and a discharge step The corresponding monitor lamp 54 is turned on among the plurality of monitor lamps 54 of the operation panel 11 when executing this series of processes. Such an enzyme water generation process is executed as many times as necessary until the generation amount of the day read from the generation schedule is reached (# 07), and the enzyme water generation process of the day is terminated. The enzyme water generated and stored in the stock tank B is drowned at the kitchen site using insulators or the like.

In this embodiment, in the initial setting process of step # 00, the update timing of the enzyme preparation is displayed on the liquid crystal display 56 as shown in FIG. As described above, the renewal time of the enzyme preparation is the remaining amount estimated from the remaining amount calculated by the remaining amount calculating unit 66a (or almost zero) and the date when the enzyme preparation is expired. In addition, the display of the enzyme preparation update time is not only performed in the initial setting process of step # 00, but may be arbitrarily displayed by selecting from the menu, or may be always displayed.

  In the above-described embodiment, since the mixing rate determination unit 63c previously determines the daily mixing rate and writes it in the schedule table 64B when the bottle 8 is updated, the mixing rate on the day of use can be read from the generation schedule. did it. Instead, the mixing rate determination unit 63c may determine the mixing rate on the day of use.

In any case, the daily mixing ratio (current day mixing ratio) is determined based on the quality evaluation value of the enzyme preparation used by the mixing ratio determination section 63c calculated by the quality evaluation section 66c of the enzyme preparation management module 66. A method for calculating the quality evaluation value and a method for determining the mixing ratio from the quality evaluation value will be described with reference to the schematic diagram of FIG. Here, the quality evaluation value is expressed as an adjustment rate with respect to a reference mixing rate determined in advance by the type of enzyme preparation. As can be understood from FIG. 11, the period from the date of manufacture of the enzyme preparation to the date of installation of the bottle 8 containing the enzyme preparation (the start date of use) is defined as the first period, and the first adjustment is made according to the length of the first period. Rate: find α. An example of a relational expression for obtaining the first adjustment rate: α is as follows:
α = F (first period)
Here, if the first period ≦ 1 year, α = 1.0,
If the first period> 1 year, α = 1.1 is defined.
Furthermore, the period from the date of use of the bottle 8 (use start date) to the day of use of the enzyme preparation is defined as the second period, and the second adjustment rate: β is obtained from the length of the first period. An example of the relational expression for obtaining this second adjustment rate: β is as follows:
β = G (second period)
Here, if the second period ≦ 1 month, β = 1.0,
If 1 month <2nd period ≤ 2 months, β = 1.1,
If 2 months <2nd period ≤ 3 months, β = 1.2,
If 3 months <2nd period ≤ 4 months, β = 1.3,
... defined as ...
The first adjustment rate: α and the second adjustment rate: β are multiplied by the adjustment rate: γ, and the finally calculated mixing rate is
On-the-day mixing ratio = standard mixing ratio × (α × β) = standard mixing ratio × γ
Is required.

  The flow of the above-mentioned method for calculating the mixing ratio on the day will be described with reference to the flowchart of FIG. First, a manufacturing date, a use start date, and a reference | standard mixing rate are read from the enzyme formulation table 64C (# 31). A first period from the date of manufacture to the date of use is determined (# 32). Using the first period as a parameter, the first adjustment rate: α is calculated from the relational expression: F (# 33). Further, a second period from the use start date to the use day is obtained (# 34). Using the second period as a parameter, the second adjustment rate: β is calculated from the relational expression: G (# 35). The first adjustment rate: α is multiplied by the second adjustment rate: β to obtain the adjustment rate: γ (# 36). This adjustment rate: γ is a so-called quality evaluation value, which is an index of deterioration over time of the enzyme preparation, and becomes a larger value as the storage becomes longer. When the adjustment rate: γ is obtained, the adjustment rate: γ is multiplied by the reference mixing rate to obtain the mixing rate on the day (# 37).

  In the above description, the quality evaluation value is defined as an adjustment rate with respect to the reference mixing ratio. However, the quality evaluation value is expressed as a simple deterioration rank value, and the mixing ratio on the day can be directly derived from the deterioration rank value. A configuration in which a table is prepared in the mixing rate determination unit 63c may be employed. In any case, it is an important feature of the present invention that the mixing ratio (daily mixing ratio) in daily enzyme water generation is determined based on the quality evaluation value calculated from the quality degradation degree based on the quality aging of the enzyme preparation. It is.
