## Background
BACKGROUND
1. Technical Filed
The disclosure relates to a method and apparatus for producing mineral water, and more particularly to a method and software and hardware design of an apparatus for producing mineral water according to user's personal conditions.
2. Technical Art
Mineral substances work in human body like a plurality of meshed gears, and they must exist in the human body in specific ratios to be useful to human health. For example, excessive potassium would cause flat T-wave in electrocardiograph (EKG), deficiency of iron will cause anemia, and excessive sodium will cause hypertension. Therefore, people must take in balanced combination of mineral substances that are suitable for and easily absorbed and metabolized by human body, in order to obtain the functions that are provided by the mineral substances. Vegetables and fruits in daily diet are the main sources of the mineral substances for human body. However, according to many investigation reports, the nutrient contents, particularly mineral substances and vitamins, of currently available vegetables and fruits have obviously reduced. Some possible reasons for the largely reduced nutrient contents of vegetables and fruits include:
(1) New species of vegetables and fruits grow quickly and fail to absorb or synthesize the required types and contents of different nutrition from the soil.
(2) The modern agricultural technologies fail to provide vegetables and fruits with natural growth environment.
(3) According to the Food and Agriculture Organization (FAO) of the United Nations, chemical fertilizers are the main causes leading to serious deficiency of mineral substances in soil.
Dr. Davis, who is a biochemist at University of Texas, USA, has found from the data about the nutrients of 43 vegetables and fruits collected by the US Department of Agriculture on a long-term basis that six types of nutrients in general vegetables and fruits have significantly reduced, including proteins, calcium, phosphorus, iron, vitamin B2 and vitamin C. The percentage of reduction ranges from 6% to 38% for different minerals. According to a report on an investigation conducted under the commission of the Department of Health in Taiwan, the mineral intake from food among male and female of different ages is indeed deficient compared to the recommended mineral intake, and the degree of deficiency is ranged from 10% to 50%. As a matter of fact, the mineral intake that meets the physiological requirements is variable according to persons and living places. However, most people have difficulty in obtaining complete background data and performing complicated calculation based on such data to know the types and quantities of deficient mineral substances that should be daily supplemented to them.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Please refer to FIG. 1 that is a flowchart showing the steps included in a method for producing mineral water according to the embodiment. As shown, the method by a microprocessor unit to treat a information includes inputting basic data to obtain data about human mineral intake and data about average mineral intake from food for a user by the microprocessor unit from a database unit; selecting a water supply area to obtain data about mineral intake from daily water intake by the microprocessor unit from a database unit; selecting an eating habit and a physical/mental condition by the microprocessor unit; inputting the user's body weight for calculating required mineral intake by the microprocessor unit from a database unit; setting the user's daily water intake by the microprocessor unit from a database unit; calculating the daily mineral supplement to the user by the microprocessor unit from a database unit; and outputting the mineral water. The basic data includes sex and age. The age data are divided into several groups, including newborn infant, infant and toddler, child, adolescence, adult, aged man, and pregnant woman. The sex data are divided into male and female. Therefore, the types and quantities of mineral substances that should be supplemented to a user can be determined according to the user's basic data. Data about recommended mineral intake for different users can be obtained from related research reports and recommendation from governmental organizations and academic and research institutes. For example, the types and quantities or other related factors of mineral supplement needed by different persons can be obtained from the National Food and Nutrient Reference Intake issued by the Department of Health in Taiwan or other research reports from relevant institutes. Or, data about the average mineral intake from food calculated based on sex and age can also be obtained from the Department of Health and other relevant institutes.
The water supply area has relation with the quality of water available from an area. Therefore, investigation of local water quality must be conducted to derive data about the percentages or quantities of different minerals contained in the locally available water source. Of course, such data can also be obtained from a local water supply company or other research institutes. The water supply area is an important factor for calculating the mineral-content in drinking water. Other factors, such as the user's eating habit, physical/mental condition, and body weight, also have important influences on the user's mineral intake. Generally, data about the mineral intake for persons having different eating habits, physical/mental conditions, and body weights can be obtained from research reports by dietitians. Therefore, according to the embodiment, a user's mineral intake can be calculated based on the input data about the user's body weight and the user's daily mineral supplement from the user's daily water intake can be calculated from the following formula:

M=(a−b−c)×d×(e/standard reference weight)

where,

    a is the recommended human mineral intake selected according to the input sex and age;
    b is the average mineral intake from food calculated based on the input sex and age;
    c is the mineral intake from daily water intake calculated based on an average quality of water supplied by the selected water supply area;
    d is a multiplication factor for calculating the user's mineral intake according to the selected personal eating habit and physical/mental condition; and
    e is the input user's body weight for calculating the mineral intake.


According to the embodiment, the user's daily water intake is adapted to the user-set daily water intake (L), and the quantity of mineral supplement obtained from the above calculation is equally added into the user-set daily water intake within a predetermined water discharge time (T). From the above calculation, it is able to obtain the quantity of mineral supplement to meet the recommended mineral intake. In the event the user's water intake exceeds the user-set daily water intake, the supply of mineral substance is stopped and the water supplied is automatically switched to purified water or other differently formulated water.
The above-mentioned steps in the mineral water producing method according to the embodiment, including inputting basic data, selecting the water supply area, selecting eating habit and physical/mental condition, and inputting personal body weight, are not necessarily performed in the order sequence as shown in FIG. 1. That is, in the embodiment, the sequence of the steps of the method can be freely adjusted without influencing the production of the mineral water according to the embodiment. It is the sprit of the embodiment to produce and provide mineral water having mineral content adapted to individual users. Therefore, any and all inventive concepts similar to the spirit of the embodiment are within the protection scope of the embodiment.
The data used in the embodiment for calculation not only refer to, for example, the Recommended Human Mineral Intake issued by the Department of Health in Taiwan, but also include results from compilation and analysis of investigation reports by the Department of Health and water quality analysis reports by water supply companies, so as to establish a human daily mineral intake background database according to the influences of living area, sex, age, eating habit, and physical/mental condition on a person's mineral intake. With the data in this human daily mineral intake background database, when a user inputs personal data, it is able to calculate the deficiency of personal daily mineral intake, that is, the recommended mineral supplement.
FIG. 2 is a flowchart showing the steps included in an embodiment of the mineral water producing method according to the embodiment. In the illustrated embodiment, the mineral to be implemented is calcium. However, it is understood the embodiment is not limited to the supplementation of calcium. As a matter of fact, most of the mineral substances can be supplemented to a user through the mineral water producing method of the embodiment.
The embodiment of the mineral water producing method illustrated in FIG. 2 is based on the supply of calcium supplement and/or other mineral supplement to a user. To do so, basic data about a user is first input in order to obtain data about human mineral intake and data about average mineral intake from food for the user. The basic data includes personal data, such as the user's name, or an identification code (ID) or a representative pattern that is sufficient to represent the user's name. Then, basic data about the user's sex and age are input. For example, in the illustrated embodiment, the selected sex is female, and the selected age is adult. Please refer to the table in FIG. 4-1, 4-2, 4-3. The recommended daily calcium intake is 1000 mg for an adult woman. In the case the user is 25 years old, the average calcium intake from food is 496 mg for the user.
After the basic data have been input, a water supply area is selected, which is Hsin-Chu, for example, in the illustrated embodiment. Please refer to the table in FIG. 4-1, 4-2, 4-3. The calcium content in the water supplied within the area of Hsin-Chu is about 65 mg.
Then, an eating habit and a physical/mental condition are selected, which are, for example, “prefer meat” and “normal”, respectively, in the illustrated embodiment. According to the table in FIG. 4-1, 4-2, 4-3, a multiplication factor for the following calculation is set to 1.3 for the selected eating habit and physical/mental condition.
Then, the user's body weight is input to calculate the calcium intake. For example, the input body weight is 55 kg. Then, the user's daily calcium supplement from the drinking water produced by a mineral water producing apparatus according to the embodiment, which will be described later, can be derived by substituting the above relevant values into the formula: M=(a−b−c)×d×(e/standard reference weight). That is, M=(1000−496−65)×1.3×(55/50), with the standard reference weight being 50 kg herein, and the daily calcium supplement (M) from the daily drinking water should be 628 mg. Therefore, when the user-set daily water intake is 1 liter (L), the flow speed of the discharged water is 2 L/min, and the water discharge time is 0.5 min, within which the calculated calcium supplement is to be equally added into the discharged water, and the calcium supplement is presented as a solution having a concentration of 10000 mg/L, then the calcium supplement solution should be added into the drinking water at a flow rate F(mL/min)=(628 mg/10000 mg/L)×1000/0.5 min=125.6 mL/min.
In the event the user's water intake exceeds the preset daily water intake of 1 L, for example, the supply of the mineral supplement is stopped and the water supplied is automatically switched to purified water or other differently formulated water.
It is noted the number of items of data shown in the table of FIG. 4-1, 4-2, 4-3 can be increased, and the values of the data shown in the table can be modified when necessary. That is, while the data shown in the table of FIG. 4-1, 4-2, 4-3 are obtained from different sources and have been carefully compiled and analyzed, they are not intended to limit the embodiment in any way.
Please refer to FIG. 5 that is a flowchart showing a logic operation/control process of a mineral water producing apparatus according to the present invention. As shown, in the present invention, the range of different mineral contents in the drinking water discharged from a mineral water producing apparatus of the present invention can be controlled via a programmable logic controller. When basic data about a user is input via a touch human-machine interface or a keyboard input interface, data about human mineral intake and data about average mineral intake from food are obtained from an internal database. The basic data includes personal data, such as the user's name, or an identification code (ID) or a representative pattern that is sufficient to represent the user's name. Then, basic data about the user's sex and age are input via the touch human-machine interface or the keyboard input interface. For example, the selected sex is female, and the selected age is adult. Please refer to the table in FIG. 4-1, 4-2, 4-3. The recommended daily calcium intake is 1000 mg for an adult woman. In the case the user is 25 years old, the average calcium intake from food is 496 mg for the user. The table of FIG. 4-1, 4-2, 4-3 can be built in the internal database. After the basic data have been input, a water supply area, such as Hsin-Chu, can be selected via the touch human-machine interface or the keyboard input interface. Referring to the table in FIG. 4-1, 4-2, 4-3, the calcium content in the water supplied within the area of Hsin-Chu is about 65 mg. Then, an eating habit and a physical/mental condition, such as “prefer meat” and “normal”, respectively, can be selected via the touch human-machine interface or the keyboard input interface. According to the selected eating habit and physical/mental condition, the programmable logic controller (PLC) or a single-chip microprocessor calculates the multiplication factor and set the same to 1.3, for example. Then, the user's body weight is input via the touch human-machine interface or the keyboard input interface. According to the input body weight, the PLC or the single-chip microprocessor calculates the calcium intake. For example, the input body weight is 55 kg. Then, the PLC or the single-chip microprocessor calculates the user's daily calcium supplement from the drinking water produced by a mineral water producing apparatus of the present invention, which will be described later, by substituting the above relevant values into the formula: M=(a−b−c)×d×(e/standard reference weight). That is, M=(1000−496−65)×1.3×(55/50), with the standard reference weight being 50 kg herein, and the daily calcium supplement (M) from the daily drinking water should be 628 mg. Therefore, the mineral water producing apparatus (hardware) can be controlled to output the user-set daily water intake of 1 liter (L) at a water discharge speed of 2 L/min and to add the calculated calcium supplement in equal parts to the drinking water discharged within a water discharge time of 0.5 min each time. Supposing the calcium supplement is presented as a solution having a concentration of 10000 mg/L, then the calcium supplement solution should be added to the drinking water at a flow rate F(mL/min)=(628 mg/10000 mg/L)×1000/0.5 min=125.6 mL/min. In the event the user's water intake exceeds the preset daily water intake of 1 L, for example, the supply of the mineral supplement is stopped and the water supplied is automatically switched to purified water or other differently formulated water.
The user inputs parameters of personal data, including sex, age, living area, physical/mental condition, body weight, and daily water intake, to the PLC or the microprocessor, and the PLC or the microprocessor will compare these input parameters with data in the internal database to retrieve corresponding values. The PLC or the microprocessor then calculates based on the retrieved corresponding values to generate a mineral supplement value, which is shown on a display of the touch human-machine interface or the keyboard input interface. Meanwhile, the generated mineral supplement value is converted into a pumping flow rate. When the user touches keys on the touch human-machine interface or pushes keys on the keyboard input interface to get drinking water, the PLC or the microprocessor will direct a water conditioner to supply the drinking water and drive a pump to supply the mineral supplement concentrate to the discharged drinking water based on the calculated pumping flow rate.
Please refer to FIG. 3 that is a schematic view showing the system of a mineral water producing apparatus 10 according to an embodiment. As shown, the mineral water producing apparatus 10 includes a water inlet 11 and a water outlet 12; a first filter 20 having a first end 21 connected to the water inlet 11 and a second end 22 connected to the water outlet 12; at least one mineral substance container 30 located between and connected to the second end 22 of the first filter 20 and the water outlet 12; and a controller 40 for controlling the mineral substance container 30 to supply a mineral solution and actuate a pump 23. Running water or other drinking water is supplied via the water inlet 11 to flow through a flow stabilizer or the pump 23, which stabilizes the in-coming water or supplies a force to transfer the water through the system. The water passed through the first filter 20 is further caused to pass through an ultraviolet (UV) irradiator 50 disposed upstream of the water outlet 12 for UV sterilization, so as to ensure the cleanness of the supplied drinking water. The first filter 20 includes a filtering material, such as a filter net or screen, active carbon, or some other materials for natural filtration.
