Description

Mineral water extraction device

The present invention relates to a mineral water extraction apparatus for extracting mineral water having a target hardness from mineral water containers having different hardnesses (hereinafter abbreviated as “water container”).

Mineral water is called natural water when sterilization such as heating and filtration is performed on groundwater taken from a specific water source, and in addition to this source, natural mineral water is called natural mineral water. . On the other hand, like natural water, groundwater is used as a water source, but a mixture of several raw waters or artificially added minerals is called mineral water.

The standards and specifications of mineral water in Korea are stipulated by the Food Sanitation Act, and since the standards and specifications for each country are not all constant, a description thereof will be omitted.

In general, water is hard water, raw water, boiled water, soft water, rain water, snow water, filtered water, and deionized water. (de-ionized water) and distilled water.

Since the human body does not have a chemical action to convert inorganic minerals into organic minerals like plants, it consumes organic minerals through fresh fruits, vegetables, meat, and water.

The water we drink differs in characteristics and tastes not only in Korea but also around the world because there is a difference in the content of minerals in water, that is, the hardness of water.

The hardness of water represents the amount of dissolved calcium and magnesium numerically. If the numerical value (hardness) of calcium and magnesium dissolved in 1 liter of water is more than 300mg, it is divided into hard water, less than 100mg, soft water, and 100 to 300mg is divided into medium hard water. Are doing.

The above-mentioned soft water is soft and can be used when cooking soup, steamed rice, or noodles to maximize the taste of ingredients, and when used when brewing kelp, the umami of kelp is well brewed and used in green tea and black tea. When you do it, the scent or color comes out well.

In addition, if you use hard water in steamed and dried ingredients such as dried anchovies or katsuobushi, the protein and calcium combine to create a bitter taste, so it is better to use medium hard water to brewer the original taste, and cook rice for fried rice or kimbap. When using junggyeong water, it is possible to weaken the stickiness by hardening the fiber of rice. In addition, using junggyeong water has the effect of reducing or removing the sour taste of coffee that has a sour taste.

In addition, if you use hard water when cooking meat such as pork, beef, or chicken, calcium and light protein are combined to soften the meat quality and at the same time remove the peculiar smell of the meat. Noodles such as pasta If hard water is used, it is good to boil it with the right thickness and does not swell well.

In addition, tea is better to use soft water than hard water because it changes into other components as the nucleic acid-based substances such as amino acids and glutamic acid, which are taste components, are combined with calcium.

In general, it is reported that the taste of water among the mineral components in water, calcium, potassium, and silicic acid improves the taste of water, and that magnesium, sulfate ions, and chlorine worsen.

Therefore, the condition of good water is not water with high mineral content, but water with balanced minerals is good water, but this criterion is not meaningful for a specific use, so it is unreasonable to see it as a common standard for the use of water.

The brand names "Hite Jinro Seoksu" and "Whistler Water (hardness 47mg/ℓ, pH 7.2)" are soft water products, and "Puriss", "BlueAqua" and "FIJI" water are medium hard water. Product, and "Perrier" is a hard water product.

Although it has been confirmed that water has different tastes and unique efficacy by hardness, as described above, research related to the manufacture of customized mineral water has not yet been attempted, but the awareness of its effectiveness and necessity has gradually increased as awareness of health increases. It is on the rise.

As technologies related to the manufacture of mineral water, there are Korean Patent Registration 10-0589795 (Method of producing beverage from deep sea water) and Korean Patent Registration 10-0654683 (Drinking water production system using deep sea water in East Sea).

It relates to a method of manufacturing beverage, and Patent No. 10-0654683 proposes a method of manufacturing beverage through a desalination system and a water quality adjustment system after pretreatment, but there is a considerable distance from custom manufacturing of minerals by a user.

Only parts necessary for understanding the mineral water extraction apparatus and the extraction method according to an embodiment of the present invention described below will be described, and descriptions of other parts may be omitted from the scope in which the gist of the present invention is not diluted.

Mineral water defined in the present invention encompasses natural mineral water, natural water, and mineral water mentioned in the background art.

For reference, the water extrusion means and the storage container described below are combined in a 1:1 ratio equal to the number of water containers, but each configuration is the same, so it is described through any one set (water storage container, water extrusion means). And for the same configuration, the same reference numbers are indicated.

The control panel 130, as shown in FIGS. 1 to 3, includes the following modules for electrically/circuitly controlling various hardware installed in the mineral water extraction device 100 and software for determination and control. The circuit board is collectively referred to as a hardness and flow rate selection module (hereinafter referred to as “selection units 131 and 131b”), and a setting module in which container reference values and operation reference values are set in advance (hereinafter “setting unit 108”). ), a storage unit 106 made of a semiconductor memory, a determination module that determines the contrast between the sensing information and the setting value of the setting unit (hereinafter referred to as “determining unit 104”), and a water extruding means according to the determination result of the determination unit. A control means for controlling (hereinafter referred to as “control unit 105”), a display unit 107 and a reset unit 110 for displaying the determination result and sensing information of the determination unit are provided.

The hardness and flow rate selection units 131 and 131b are modules for user to set the desired hardness value and flow rate value, respectively, and as shown in FIG. 3, the user's desired hardness and flow rate are independently selected in a digital manner or It includes a means to be specified. The selected hardness and flow rate setting values are transmitted to the determination unit 104, respectively.

The above-described hardness selection unit 131 may be a subdivided button of a hardness setting value as shown in FIG. 3 or a dial-type knob capable of specifying an arbitrary hardness setting value in a specific hardness setting value (digital) range.

The flow rate selection unit 131a may be in the form of a button or a knob mentioned in the above-described hardness selection unit 131 or may be any one of a timer. Hereinafter, the flow rate selection unit 131a will be described as an example of employing a timer.

The setting unit 108 shown in FIG. 2 is a nonvolatile semiconductor memory in which a proportional control value for controlling the actuators of both water extruding means (hereinafter referred to as “driving unit”) is stored in advance. A control value for proportional control of the water extrusion means (this is referred to as a "proportional control value") and reference information regarding the weight (weight), size, pressure, etc. of the water container 120 are stored.

The storage unit 106 of FIG. 2 is a nonvolatile semiconductor memory for updating sensing information on the water container 120 or the state of water contained in the water container, and main power applied to the mineral water extraction device 100 from the outside. When this is blocked, all information recorded in the memory is suspended.

The determination unit 104 of FIG. 2 is a module that programmatically compares and determines the sensing information of the container sensing means to be described later with a set value set in the setting unit 108 and transmits the determination result to the control unit 105.

The control unit 105 of FIG. 2 alarms the display unit 107 according to the determination result of the determination unit 104 and controls the water extruding means 140.

The reset unit 110 of FIG. 2 separates the water extruding means 140 to a predetermined position when the reset signal is sensed, that is, the water extruding means 140 from the water container when the water container is withdrawn or received from the storage container. To separate, the drive unit is controlled through the control unit.

The reset unit is arranged in the form of a button on the control panel 130 so as to be circuitly connected to the control unit, and is turned on when necessary, or by attaching the reset button or a specific sensor (see Fig. 12b 111a) to the lid of the storage container to be described later. It may be installed to be turned on or sensed in conjunction with the opening and closing operation of. In response to the sensing signal of the reset button, the control unit controls the driving unit of the water extruding means 140 to be transferred to a predetermined position and separated from the water container.

In order to sense the operating state of the water extruding means, that is, the position of the pressurizing member, a position sensor (not shown in the drawing) is attached, and the control unit determines the position according to the presence or absence of the sensing information, and whether the operation is started or not through the determined information. Control.

The above-described control panel 130 is provided with an extraction start button (not shown).

The mineral water extraction apparatus 100 according to the present invention includes at least one extraction port 121 as shown in FIGS. 4 to 8 and water containers 120 containing mineral water having different hardnesses,

A storage container (101a) that exchangeably accommodates the water container (120),

Hardness and flow rate selection unit (131a) for setting the hardness and flow rate of mineral water,

A water extrusion means 140 for pressurizing the water container 120 or water,

And a control unit 105 for proportionally controlling the both water extrusion means 140 until the flow rate set value is reached through a proportional control value.

The above-described case 101 includes a tray 102 for a drip tray disposed at the bottom, a machine room (not shown) in which the water container 120 and the storage container 101a described above are built, and the tray 102 and the machine room. There is a space (not shown in the drawing) where cups or water bowls are placed between them.

Between the machine room and the tray 102, a discharge port 103 communicating with an extraction port is provided on the surface of the upper case 101 of the space described above, and the control panel 130 is coupled to the front of the machine room.

The water container 120 described above may be in the form of a cylinder (not shown in the drawing) of a medical injector equipped with an extraction port 121 or a bellows form as shown in FIG. 9. Among them, the hollow bellows form is more preferable.

The reason is that both the cylinder-type and bellows-type water containers have the advantage of hygienic storage of mineral water, but when extracting mineral water from the water container, the outside of the water container 120 is pressurized and the inside thereof is This is because you have to consider which of the pressurization is more effective.

In this respect, the bellows type water container 120 can hygienically protect and preserve the quality of mineral water, and it is easy to exchange and handle the water container 120, and compress the water container 120 and This is because the expansion direction can be maintained collectively, and it is easier to connect the water extruding means 140 to be interlocked with the water container 120, and it is possible to uniformly compress the water container as a whole.

Hereinafter, the water container will be described as an example employing a bellows shape, but the above-described cylinder-shaped water container 120 is not excluded.

Almost similar effects can be expected by replacing the cylinder-shaped water container 120 with the bellows-type water container 120 described above, and in doing so, those with ordinary knowledge in the technical field to which the present invention belongs will not have any difficulty. .

The above-described extraction port 121 is a conduit for guiding mineral water to be extracted from the water container, and as shown in FIG. 10A, a check valve 122 and a UV sterilization lamp (not shown in the drawing) may be further coupled.

In that case, since the pipeline of the check valve 122 is opened only when the water pressure in the water container increases, the mineral water in the water container is contaminated by various pollutants introduced through the above-described extraction port 121 or oxidized by air. It can be prevented, the sanitary safety of mineral water can be secured, and the quality of mineral water can be preserved for a longer period of time. Also, when the water container is taken out of the storage container, it is Since air does not flow in, the volume of the water container drawn out of the storage container does not expand.

So, the water container taken out of the container can be reloaded into the container as it is.

In addition, when the above-described both extracting ports 121 are provided in the water container 120 in close proximity to each other, as shown in FIG. 7, both extracting ports 121 can be integrated into a single discharge port 103. The configuration of the above-described UV sterilization lamp (not shown in the drawing) and the water discharge system can be shortened to the shortest length, and the mineral water extracted through both extraction ports 121 through the UV sterilization lamp remains in the discharge port 103 Any residual water can be sterilized together.

However, when a cold/hot function is attached, it may be useful to connect the outlet 103 to each of the hot and cold water outlets (not shown in the drawings) in a 1:1 manner.

In addition, the aforementioned extraction port 121 includes a coupling port 101c communicating with the discharge port 103 at the bottom of the storage container 101a as shown in FIG. 10B when the water container 120 is mounted in the storage container 101a. It is preferable to connect the water container to be fixed to the coupling hole 101c by providing a helical portion (not shown) to be helically fastened. In FIG. 10B, reference numeral 122a denotes an awl, and when the spout 121 is coupled to the coupling hole 101c, the pipe of the spout 121 is formed by the awl. Therefore, when the water container is compressed, the check valve 122 is opened and water is extracted.

In this way, since the water container can be fixed in the storage container 101a, it is possible to prevent the mineral water extraction device from falling for unpredictable reasons or the water container being separated from the storage container due to an external impact.

The storage container 101a described above is a protective container of the water container 120 that is sized to surround the water container 120 and accommodates the water container 120 to be exchanged, and its circumference is an insulating material (drawing It may be covered with (not shown), and an openable lid (not shown in the drawing) may be coupled to the periphery thereof.

The storage container (101a) is provided in a quantity corresponding to the quantity of the water container (120) 1:1, and is fixedly mounted in the upper machine room of the discharge port (103).

The storage container 101a has a peripheral portion open so that the water container 120 can enter and exit in FIGS. 4 to 7, but as shown in FIGS. 7A and 7B, the peripheral part of the storage container 101a or its upper case 101 ), the lid 111 can be opened and closed to open and close the storage container 101a.

The hardness setting value and the flow rate setting value (ie, time) specified by the hardness selection unit 131 and the flow rate selection unit 131a are displayed in real time on the display unit 107 of the control panel 130 and start extraction. When the button (not shown) is turned on, it is transmitted to the control unit 105.

The container sensing means described above encompasses specific sensor elements for detecting the state of the container such as the weight, pressure, and height of the water container 120. Conceptually, a specific sensor capable of sensing the pressure, weight, and height of the water container 120 is mounted around the upper water container or the storage container 101a to sense the state of the water container in real time.

As an example, if the weight sensor 101b is installed on the bottom of the storage container 101a as shown in FIGS. 7 and 11, the weight of the water container 120 can be sensed in real time.

The above-described water extruding means 140 includes means for extruding mineral water from the water container 120, and in doing so, the driving unit 141 controlled by the control unit as shown in FIGS. 11A and 11B and , It is characterized in that it is composed of a pressing member 146 linearly moving with respect to the rotational movement in the driving unit 141.

It is preferable that the above-described pressing member 146 is configured in a shape capable of covering one side of the water container to evenly compress the surface of the water container.

The water extruding means 140 including a pressure member 146 that moves linearly in connection with the rotational motion is controlled by a control value of the control unit and a screw shaft 144 that is interlocked with the driving unit 141 coupled to the base 145 And, it is implemented by the coupling of the shaft 144 and the pressure member 146 spirally coupled.

That is, while the shaft 144 rotated by the driving unit 141 and the pressing member 146 spirally coupled are moved forward and backward, the water container 120 is pressed and compressed. In FIG. 11A, reference numeral 143 is a guide shaft for smoothly guiding the movement of the pressing member, 144a is a sleeve fixed to the pressing member 146 and helically coupled with the shaft, and 147a is for sensing the position of the pressing member. A sensor, 147 is a slider coupled to the pressing member and slidably coupled to the guide shaft 143, 111a of FIG. 12B is a sensor for sensing whether the lid 111 is opened or closed.

Both of the above-described driving units are step motors driven by a pulse voltage, and are proportionally controlled by the control unit, and the proportional control will be described in detail in the latter part.

The above-described water extrusion means 140 may be mounted on the lower portion of the storage container, but is preferably coupled on the coaxial line of the water container.

In this way, the pressing member 146 can be compressed in the axial direction of the water container 120, and the space of the machine room can be compactly reduced.

After placing a spacer (not shown) having a predetermined volume between the above-described pressing member 146 and the water container 120, the water container 120 may be compressed through the spacer.

In this way, since the space between the lid 111 and the storage container 101a can be appropriately adjusted through the spacer described above, it may be useful when the capacity of the water container 120 is small, and the spacer is omitted. It may be useful when designing a large capacity of the water container 120.

In addition, when compressing the water container through the pressing member 146, a plate-shaped body may be placed between the water container and the pressing member 146 to pressurize the upper portion of the water container.

In this way, since the compression force of the pressing member is evenly distributed, the water container can be compressed uniformly.

A method for extracting mineral water according to the present invention configured as described above will be described.

In general, it is assumed that the mineral water extraction apparatus 100 is powered by the power supply unit 109.

In the mineral water extraction method of the present invention, the flow rate from both water containers is proportional by controlling each water extruding means through a proportional control value, respectively, until the flow rate set value is reached with control values corresponding to the hardness set value by the controller. It has a characteristic of extracting as an enemy.

In advance, the control unit 105 performs a process of determining whether the water container 120 is properly loaded in the storage container 101a, whether the charged water container 120 is a standard product, and whether the water is within a set range. (This is called the "pre-operation inspection step.).

The above pre-operation inspection step is to check the state of the water container by comparing the sensing information of the container sensing means described above with the set value of the setting unit by the determination unit 104 (FIG. 4).

When the weight value sensed through the weight sensor 101b whether or not the water container 120 is inserted in the storage container 101a is smaller than the weight set value previously stored in the setting unit 108, the determination unit 104 is the storage container 101a. ) Is determined to be empty, and according to the determination result, the control unit 105 alarms through the display unit 107 that the water container 120 is not loaded into the storage container 101a,

If the sensed weight value is greater than the set value, since the non-standard water container 120 or an article other than the water container 120 is loaded, the determination unit 104 sends a signal indicating that the water container 120 is non-standard. Transmits to the control unit 105, and the control unit 105 alarms the corresponding signal to the display unit 107,

When the sensed weight value is within the set value range, the above-described control unit 105 alarms the sensing value to the display unit 107 in the above-described manner and controls the driving units of both water extruding means in response to the sensed weight value. ), the water extruding means is set to a state in which the water container can be immediately compressed according to the state of the water container 120.

When the hardness and flow rate values are set through the above-described both selection units 131 and 131a, and then the extraction start button is turned on (S2), the controller 105 increases the sum of the flow rates extracted from both water containers to 100. Both control values are set so that the control unit proportionally controls (On) the driving units of both water extrusion means 140.

Table 1 below shows an example of a proportional control value for proportionally controlling the flow rate extracted from both water containers according to the selected hardness.

A Water container water extraction flow rate (cc) 0 97 95 90 80 70 60 50 30 0 B Water container Water extraction flow rate (cc) 0 3 5 10 20 30 40 50 70 100 Set hardness (HB) 0 30 50 100 200 300 400 500 700 1000

For example, if the hardness of A water container is 0HB and the hardness of B water container is 1,000HB and the desired hardness is 100HB, 90cc for A water container and 10cc for B water container are extracted. The control unit proportionally controls the drive unit of the extrusion means through both control values until the selected flow rate is reached.

The control unit 105 proportionally controls the driving units of both water extruding means through the proportional control value for each water container set in the setting unit, so that the proportional flow rate is extracted from both water containers 120 respectively (this is referred to as “water extraction step”. It is called.).

In the above water extraction step, the determination unit transmits the weight value of the container that has sensed the state of the water container 120 in real time through the container sensing means, that is, the weight sensor, to the determination unit and is updated to the storage unit 106, so that the main power is not cut off. Unless the water extruding means is kept in a state capable of directly compressing the water container 120, the remaining amount of the water container 120, that is, the replacement time, is displayed on the display unit 107 at the same time.

The drive unit of both water extrusion means is controlled (On) by the control unit until the flow rate set value, that is, the time set by the timer, and is controlled to be stopped by the control unit 105 when the target flow rate value is reached.

Since the water hardness in the two water containers 120 are different from each other, the water in one side of the water container 120 may sometimes be consumed relatively faster. That is, the determination unit determines the state of both water containers 120 through the container sensing means, and according to the result, the control unit 105 alarms the information corresponding to the determination result to the display unit 107 in real time. If the remaining amount of mineral water in both water containers or one of the water containers is less than the lower limit set value, the control unit 105 controls the drive unit so that both water extruding means 140 are stopped.

In this way, the remaining amount of water in the water container 120 is displayed on the display unit 107, but even if the water container 120 is reloaded into the storage container 101a, the water extruding means described above is suitable for the state of the water container 120. The container is set in a state that can be compressed immediately.

On the other hand, when the water container 120 needs to be removed from the storage container 101a during use or needs to be replaced with a new water container 120, the reset button provided on the control panel 130 is turned on or the opening and closing state of the storage container lid is changed. Since the above-described water extruding means is set according to the state of the water container 120 in the same manner as described above through the sensing signal of the reset button (sensor) installed to be sensed, the water container 120 is placed in the storage container 101a. Can be charged.

As described above, according to the present invention, by proportionally controlling the water extruding means through the control unit, mineral water having a target hardness can be extracted from the water containers by a set flow rate.

In the embodiments according to the present invention exemplified above, a person with ordinary knowledge in the technical field to which the present invention belongs may implement various application examples or modified examples based on the present invention.
