Description
Cross Reference to Related Applications
This application claims priority to korean patent application No.10-2015-0000903, filed on 5/1/2015, which is incorporated herein by reference as if fully set forth herein.
Technical Field
The present invention relates to a drinking water supply apparatus capable of supplying mineral water, and more particularly, to a drinking water supply apparatus capable of displaying a residual amount of minerals so that a user can easily recognize a time when a mineral cartridge should be replaced.
Background
Generally, a drinking water supply device is a device that supplies drinking water to a user. The drinking water supply device may be a stand-alone device, or may form part of an electronic household appliance such as a refrigerator.
The drinking water supply apparatus may supply room-temperature drinking water to a user. In addition, the drinking water supply apparatus may cool the drinking water using a cold water supply unit including a refrigeration cycle, or may heat the drinking water using a heater. That is, the drinking water supply apparatus may supply cold or hot water to a user as needed.
The drinking water may be ground water, raw water supplied from a faucet, or clean water obtained by filtering the raw water supplied from the faucet using an additional filtering apparatus. However, in the following description, drinking water will be defined as drinkable water. Drinking water is not limited to the above-defined water.
In recent years, drinking water supply apparatuses have been developed which can provide functional water satisfying various demands of users in addition to clean water, cold water, or hot water, which has been filtered, to users. For example, the drinking water supply may include a mineral water supply module capable of providing mineral water to a user, the mineral water containing a predetermined amount of minerals.
Minerals and proteins, fats, carbohydrates and vitamins together make up five types of nutrients. Minerals play an important role in the biochemical activity (e.g., catalytic activity) of the human body and in the composition of bones, teeth, and the like.
In particular, calcium (Ca), potassium (K), magnesium (Mg) and sodium (Na) are essential mineral elements for metabolism.
Mineral water containing these minerals may play an auxiliary role in improving user health, such as discharging waste from the human body and promoting metabolism.
In the case where the drinking water contains a predetermined amount of minerals, the taste of the water may be better for the user when the user drinks the water.
In order to generate such mineral water, an electrical analyzer, a mineral filter, or a mineral water supply module for directly supplying concentrated minerals into clean water may be applied to the drinking water supply apparatus.
The mineral water supply module for directly supplying concentrated minerals into the clean water may have a more compact size than other types of mineral water supply modules.
For example, the mineral water supply module for directly supplying concentrated minerals to the clean water may be configured to have a structure of: minerals discharged from a mineral cartridge for storing a concentrated mineral liquid are supplied to a water discharge pipe through a mineral supply pipe.
The mineral cartridge may store minerals corresponding to the amount of minerals based on the mineral water produced a predetermined number of times or the amount of minerals capable of producing a predetermined amount of mineral water.
In the case where the minerals stored in the mineral cartridges have been exhausted, or in the case where the effective periods of the minerals stored in the mineral cartridges have expired, the mineral cartridges must be replaced.
However, in the case of information only about that the minerals stored in the mineral cartridge have been used up, a user may not drink mineral water until the mineral cartridge is replaced, which is inconvenient.
Therefore, information on the residual amount of minerals stored in the mineral cartridge must be provided to the user.
In addition, when energy is applied to minerals having high hardness, the minerals may be crystallized and thus form scale. Scale can reduce the cross-sectional flow area of the tube. As a result, the flow of minerals may be blocked and the valve may fail.
Therefore, there is a high need for an apparatus or method capable of sensing a malfunction of a mineral water generating module based on whether minerals are discharged.
Disclosure of Invention
Accordingly, the present invention is directed to a drinking water supply apparatus that substantially obviates one or more problems due to limitations and disadvantages of the related art.
An object of the present invention is to provide a drinking water supply apparatus capable of displaying the residual amount of minerals in a mineral cartridge so that a user can easily recognize the time when the mineral cartridge should be replaced.
It is another object of the present invention to provide a drinking water supply apparatus capable of rapidly sensing malfunction of a mineral water supply module and appropriately taking follow-up measures.
It is a further object of the present invention to provide a drinking water supply apparatus capable of visually informing a user of a residual amount of minerals or a malfunction of a mineral water supply module, thereby improving usability of the drinking water supply apparatus.
Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objectives and other advantages of the invention will be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.
To achieve these objects and other advantages and in accordance with the purpose of the invention, as embodied and broadly described herein, a drinking water supply apparatus includes: a housing forming an external appearance of the drinking water supply apparatus; a water supply pipe in which clean water flows; and a discharge pipe for discharging clean water or mineral water.
The drinking water supply apparatus further includes a mineral water supply module including: a mineral supply pipe having a micro channel unit for supplying a very small amount of minerals to the water supply pipe; a mineral cartridge connected to the mineral supply pipe for storing a predetermined amount of concentrated minerals; a pump for discharging minerals stored in the mineral cartridge to the mineral supply pipe; and a mineral water generating unit connected to the water supply pipe and the mineral supply pipe, the mineral water generating unit having a mixing space in which the mineral is mixed with the clean water.
The drinking water supply apparatus may further include a mineral discharge sensor disposed in the mineral supply pipe for sensing discharge of minerals. In particular, the mineral discharge sensor may sense whether minerals have been discharged and the amount of minerals that have been discharged.
In addition, the drinking water supply apparatus may further include a controller for confirming whether the mineral water supply module is abnormal based on whether the minerals sensed by the mineral discharge sensor have been discharged, and calculating a residual amount of the minerals stored in the mineral cartridge based on the sensed amount of the minerals that have been discharged.
The controller may display the residual amount of the minerals through a display unit provided at the cabinet to provide information on the residual amount of the minerals to a user.
Upon receiving a signal indicating that the mineral cartridge has been installed, the controller may initialize the amount of mineral stored in the mineral cartridge and may subtract the amount of mineral that has been discharged, as sensed by the mineral sensor, from a previous amount of mineral stored in the mineral cartridge to calculate a current residual amount of mineral.
Further, the controller may select one of the plurality of display modes corresponding to the calculated current residual amount of the minerals to display the residual amount of the minerals.
Meanwhile, the mineral discharge sensor may be a flow sensor or a pressure sensor.
In the case where the mineral discharge sensor is a flow sensor, the controller may determine that the mineral water supply module is abnormal when the amount of minerals, which have been discharged, sensed by the mineral discharge sensor does not change for a predetermined time.
When the abnormal state of the mineral water supply module repeatedly occurs a predetermined number of times or more, the controller may display a message indicating that the mineral water supply module must be checked through the display unit.
In case that the mineral discharge sensor is a pressure sensor, when the pressure sensed by the pressure sensor remains equal to or lower than a predetermined value for a predetermined time or the sensed pressure does not vary for a predetermined time, the controller may determine that the mineral water supply module is abnormal, and may inform the user that the mineral water supply module is abnormal.
In another aspect of the present invention, a method of displaying a residual amount of minerals in a drinking water supply apparatus includes: sensing a flow of minerals discharged from the mineral cartridge to the mineral supply pipe using a mineral discharge sensor (a mineral discharge sensing step); subtracting the amount of the minerals sensed in the mineral emission sensing step, which have been already emitted, from the previous amount of the minerals to calculate the current residual amount of the minerals (residual amount calculating step); and displaying the current residual amount of the minerals in the mineral cartridge on a display unit (residual amount display step).
After the residual amount calculating step, a residual amount range selecting step may be performed: the controller selects one of a plurality of predetermined residual amount ranges of minerals corresponding to the calculated amount of the mineral.
The residual amount display step may be performed: one predetermined residual amount display mode preset to correspond to a residual amount range of minerals among a plurality of predetermined residual amount display modes is displayed on the display unit under the control of the controller. The displayed residual amount display mode may correspond to the calculated residual amount of the minerals
As a result, the user confirms the residual amount of minerals in the mineral cartridge through the display unit, so that the user can replace the mineral cartridge at an appropriate time.
Meanwhile, when the discharge of minerals has not been sensed for a predetermined time in the mineral discharge sensing step, the abnormal state sensing step may be performed: sensing that the mineral water supply module is abnormal, and sensing whether an abnormal state of the mineral water supply module has repeatedly occurred a predetermined number of times or more.
When the abnormal state of the mineral water supply module has repeatedly occurred a predetermined number of times or more, the fault notification step may be performed: notifying the user that the mineral water supply module has failed.
It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.

DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.
Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. For convenience and clarity of description, the size and shape of elements in the drawings may be exaggerated or reduced.
Meanwhile, terms including ordinal numbers such as first and second are used in this specification to describe various elements. However, the elements are not limited by the terms, and the terms are only used to distinguish the elements.
In the following description, water to be passed through a filter will be defined as raw water, raw water having passed through the filter will be defined as clean water, and clean water containing minerals will be defined as mineral water. Further, the rear end and the front end may mean an upstream side and a downstream side in a direction in which the fluid flows forward.
Fig. 1 is a view showing an example of a drinking water supply apparatus. Hereinafter, an appearance of a drinking water supply apparatus according to an embodiment of the present invention will be described with reference to fig. 1.
The drinking water supply apparatus 1 includes: a housing 2, the housing 2 forming an external appearance of the drinking water supply apparatus 1; and a dispenser 3. The dispenser 3 is a space in which drinking water is supplied to a user. Therefore, the dispenser 3 is generally formed on the front of the cabinet 2.
The dispenser 3 may be provided with a tap 73, through which tap 73 the drinking water is discharged. In addition, the dispenser 3 may also be provided with an operation lever 4, and the operation lever 4 is manipulated to discharge the drinking water. That is, the user may manipulate the operation lever 4 to discharge the drinking water through the tap 73. The operating lever 4 can be pushed or pulled.
The drinking water supply apparatus may provide clean water, cold water, or hot water as drinking water. In addition, the drinking water supply apparatus 1 may provide various functional water as drinking water. The cabinet 2 may thus be provided with a user interface 5 for selecting the drinking water that should be discharged.
The drinking water supply apparatus 1 may further include a mineral water supply module for supplying mineral water that tastes better and improves the health of the user. The mineral water supply module may include a mineral cartridge for storing concentrated minerals such that a predetermined amount of minerals is supplied to the clean water.
However, as described above, in order to improve convenience, information on the residual amount of minerals in the mineral cartridge must be provided. In addition, the user must also be easily made aware of when the mineral cartridge should be replaced.
To this end, the drinking water supply apparatus 1 according to the present invention may further include a display unit 500 provided at the cabinet 2 for displaying information on the residual amount of minerals in the mineral cartridge 140. The display unit 500 may also inform the user when the mineral cartridge 140 should be replaced. As shown in fig. 1, the display unit 500 may be provided separately from the user interface 5. Alternatively, the display unit 500 may be integrally formed with the user interface 5.
Hereinafter, the structure and pipe arrangement of the drinking water supply apparatus equipped with the mineral water supply module according to the embodiment of the present invention will be described with reference to fig. 2.
The drawings illustrating the drinking water supply apparatus of the present invention in the illustrated form are provided only to describe the present invention in detail and do not limit the technical scope of the present invention.
The drinking water supply apparatus 1 may convert raw water introduced into the drinking water supply apparatus 1 through the external tap 10 into clean water using the filter unit 20. The configuration of the filter unit 20 may be changed in various ways. A plurality of single filters may constitute the filter unit 20. In fig. 2, three filters are connected in series with each other to constitute a filter unit 20. However, the present invention is not limited thereto.
In particular, the filter unit 20 may include a pre-carbon filter 21, an ultra-filtration (UF) filter 22, and a post-carbon filter 23. Depending on the situation, another type of filter may be added.
The filtered raw water, i.e., clean water, may be discharged to the outside through the clean water pipe 30, the clean water supply valve 32, and the faucet 73.
The drinking water supply apparatus 1 may be configured to supply cold or hot water according to the user's needs.
The heated clean water, i.e., the hot water, can be discharged from the drinking water supply apparatus 1 through the first branch clean water pipe 301, the heating unit 51, the hot water pipe 50, the hot water supply valve 52 and the tap 73, which are branched from the point a of the clean water pipe 30.
The cooled clean water, i.e., cold water, can be discharged from the drinking water supply apparatus 1 through the second branch clean water pipe 302, the cooling unit 41, the cold water pipe 40, the cold water supply valve 42 and the tap 73, which are diverged from the point B of the clean water pipe 30.
For convenience of description, fig. 2 shows an embodiment in which clean water, cold water, and hot water are discharged through a single tap 73. Alternatively, taps for discharging clean water, cold water, and hot water may be separately provided. In addition, clean water and cold water may be discharged through one faucet, and hot water may be discharged through the other faucet. Therefore, the configuration of the faucet for discharging water is not limited to the drawings.
Meanwhile, a tap valve 74 may be provided at the rear ends of the clean water supply valve 32, the cold water supply valve 42, and the hot water supply valve 52. A tap valve 74 may be connected to the dispensing line 60. The distribution pipe 60 may be connected to the clean water pipe 30, the cold water pipe 40, and the hot water pipe 50.
A water discharge pipe 70 may be provided at the rear end of the tap valve 74, through which water discharge pipe 70 clean, cold or hot water may be supplied.
Therefore, clean water, cold water, or hot water may be supplied into the distribution pipe 60, and when the tap 73 is opened using the single tap valve 74, clean water, cold water, or hot water may be selectively supplied through the water discharge pipe 70.
Meanwhile, a mineral water supply module 100 for generating mineral water may be connected to the water discharge pipe 70.
The mineral water supply module 100 may be connected to one side of the water discharge pipe 70 via a mineral water generating unit 120 connected to the water discharge pipe 70.
Hereinafter, for convenience of description, a portion of the water discharge pipe 70 located at the front end of the mineral water generating unit 120 and connected to the mineral water generating unit 120 will be referred to as a water supply pipe 71, and a portion of the water discharge pipe 70 connected to the rear end of the mineral water generating unit 120 will be referred to as a discharge pipe 72.
That is, the water supply pipe 71 is a pipe: when the tap 73 is opened by the single tap valve 74, clean water, cold water, or hot water is selectively discharged and introduced into the mineral water generating unit 120 through the water supply pipe 71.
The discharge pipe 72 is a pipe that: through the discharge pipe 72, clean, cold or hot water having passed through the mineral water generating unit 120 or mineral water generated by the mineral water generating unit 120 is selectively discharged to the faucet 73 according to a user's selection.
The mineral water supply module 100 may include a mineral water supply pipe 110 connected to the mineral water generating unit 120 for supplying minerals.
The mineral water supply pipe 110 may be provided with: a mineral cartridge 140 for storing a concentrated mineral liquid; a pump 160 for pressurizing the mineral cartridge 140 to discharge minerals; and a mineral supply valve 130 for selectively supplying minerals to the mineral water producing unit 120.
Meanwhile, the minerals supplied from the mineral water supply pipe 110 to the mineral water producing unit 120 may be concentrated minerals of high concentration.
The mineral cartridge 140 may store a concentrated mineral liquid in which calcium (Ca), potassium (K), magnesium (Mg), and sodium (Na) are mixed.
For example, the concentration of the concentrated mineral liquid stored in the mineral cartridge 140 may be about 200 times the average concentration of minerals contained in the clean water.
According to the experimental results, the amount of concentrated mineral liquid required to synthesize mineral water having a taste preferred by the user is 0.0006 parts per one part of clean water, which is extremely small. Furthermore, each time in order to provide mineral water with a taste within the allowable deviation, a predetermined fixed amount of mineral must be provided for a predetermined time.
Therefore, as described above, a predetermined very small amount of minerals must be constantly supplied for a predetermined time. For this, the mineral water supply module 100 requires the microchannel unit 200 capable of supplying a very small amount of minerals.
The microchannel unit 200 may be formed in a cylindrical or polyhedral shape having a predetermined area and a predetermined length. In the case where the pressure from the pump 160 is not constant, the amount of minerals discharged from the microchannel unit 200 may be determined based on the area and length of the microchannel unit 200.
In order to supply a predetermined very small amount of minerals to the mineral water generating unit 120 for a predetermined time, the micro channel unit 200 may have a small cross-sectional area. In addition, the microchannel unit 200 may have a predetermined length to cause a loss of fluid pressure.
In particular, in the case where the microchannel unit 200 is formed in a cylindrical shape, the diameter of the microchannel unit 200 may vary from 0.5mm to 1.0 mm.
The maximum diameter of the micro channel unit 200 may be set to supply minerals within a predetermined range of allowable deviation.
In particular, when mineral water and clean water are alternately discharged, the diameter of the micro channel unit 200 may be set to extract clean water or mineral water within an allowable deviation of taste of water.
That is, when clean water is discharged after discharging mineral water, the diameter of the microchannel unit 200 may be set to minimize discharge of minerals remaining in the microchannel unit 200, and thus clean water containing minerals within a concentration allowable range is discharged.
On the other hand, when the mineral water is discharged after the discharge of clean water, the diameter of the micro channel 200 may be set to discharge the mineral water containing minerals within a concentration allowable range.
The minimum diameter of the microchannel unit 200 may be 0.5mm, enabling the microchannel unit 200 to be formed and machined at 0.5 mm. If the minimum diameter of the microchannel unit 200 is less than 0.5mm, it is not easy to mold and machine the microchannel unit 200, with the result that productivity is lowered.
The maximum diameter of the micro channel unit 200, which satisfies the above conditions and is experimentally derived, may be 1.0 mm.
The diameter of the micro channel unit 200 defined as above is derived based on a water supply pipe having an outer diameter of 6.35mm and a pump having a discharge flow rate of 0.1ml/s to 1ml/s, which are commonly used in drinking water supply devices.
In the case where the microchannel unit 200 is formed in a polyhedral shape, the minimum area of the microchannel unit 200 may be set so that the microchannel unit 200 can be molded or machined.
The micro channel unit 200 may have a predetermined length range to reduce the pressure applied to the mineral flowing in the micro channel unit 200 to thus discharge a predetermined amount of the mineral.
As a result, the transient variation in the flow rate caused by the pressure variation, which may occur due to the operation of the pump 160, can be reduced.
In particular, in the case where the micro channel unit 200 has a length less than the lower limit of the predetermined length range, a decrease in pressure applied to the mineral flowing in the micro channel unit 200 is small, with the result that more mineral than a predetermined amount of mineral can be discharged. That is, in the case where the micro channel unit 200 is short, the pressure applied to the minerals introduced from the mineral supply pipe 110 is not sufficiently reduced due to frictional loss, and as a result, the amount of the minerals to be discharged may be greater than a predetermined amount of the minerals that should be discharged.
On the other hand, in the case where the micro channel unit 200 is longer than the upper limit of the predetermined length range, the pressure applied to the mineral flowing in the micro channel unit 200 is excessively reduced due to friction, with the result that less mineral than the predetermined amount of mineral may be discharged.
Therefore, in order to discharge a fixed amount of minerals within an appropriate range, the microchannel unit 200 may have an appropriate length. In particular, the microchannel unit 200 may have a length ranging from 15mm to 20 mm.
Hereinafter, the construction of the mineral water supply module for calculating the residual amount of minerals stored in the mineral cartridge and determining an abnormal state will be described in detail with reference to fig. 3.
The mineral water supply module 100 according to the present invention includes: a water supply pipe 71 for supplying clean water; a mineral supply pipe 110 for supplying minerals; and a discharge pipe 72 through which the clean water or the clean water containing minerals, i.e., the mineral water base, is selectively discharged whether or not the minerals are supplied.
The mineral water supply module 100 may include a mineral cartridge 140 for storing concentrated minerals and a mineral cartridge receiving unit 150 for connecting the mineral cartridge 140 to the mineral supply pipe 110. In addition, the mineral water supply module 100 may further include a pump 160 for pressurizing the mineral container 140 or the mineral supply pipe 110 to discharge the minerals stored in the mineral cartridge 140 to the mineral supply pipe 110.
The mineral supply pipe 110 may be provided with a mineral supply valve 130 for selectively opening and closing the mineral supply pipe 110 based on whether mineral water should be produced. The mineral supply valve 130 may be disposed in the mineral supply pipe 110 such that the mineral supply valve 130 is adjacent to the water supply pipe 71.
In addition, the mineral water supply module 100 may further include a mineral water generation unit 120, in which the clean water supplied from the water supply pipe 71 and the minerals supplied from the mineral supply pipe 110 are mixed to generate mineral water 120.
A first connection pipe 121 connected to the water supply pipe 71, a second connection pipe 122 connected to the mineral supply pipe 110, and a third connection pipe 123 connected to the discharge pipe 72 may be formed at the mineral water generating unit 120.
In addition, a micro channel unit 200 (which defines a mineral supply line through which a trace mineral flows through the micro channel unit 200) may be provided in the second connection pipe 122 to provide mineral water in which variation in mineral concentration is minimized. The micro channel unit 200 may define a channel in which the trace minerals constantly flow for a predetermined time to minimize variation in the amount of the minerals discharged.
Hereinafter, the mineral cartridge and the sensor for sensing the discharge of minerals will be described in detail.
The mineral cartridge 140 may be connected to the mineral supply tube 110 via a mineral cartridge receiving unit 150 that connects the mineral cartridge 140 to the mineral supply tube 110. The mineral cartridge 140 may be separately connected to the mineral cartridge receiving unit 150 such that the mineral cartridge 140 can be easily replaced when minerals stored in the mineral cartridge 140 have been exhausted or when minerals stored in the mineral cartridge 140 have exceeded a valid period.
The mineral cartridge 140 may store a predetermined amount of minerals sufficient to produce a predetermined number of times or a predetermined amount of mineral water. The mineral cartridge 140 may have a predetermined size such that the mineral cartridge can be easily installed in the drinking water supply apparatus 1, and thus the size of the mineral cartridge 140 may be limited.
Accordingly, the mineral cartridge 140 may have a predetermined size such that the mineral cartridge can be easily installed in the drinking water supply apparatus 1 and can be periodically replaced.
Meanwhile, a mineral discharge sensor 170 for sensing discharge of minerals may be provided in the mineral supply pipe 110.
The mineral discharge sensor 170 may sense whether minerals are discharged from the mineral cartridge 140 to the mineral supply pipe 110 and the amount of minerals discharged for a predetermined time.
The mineral discharge sensor 170 may be a flow sensor or a pressure sensor.
The drinking water supply apparatus 1 may further include a controller 400 for calculating a residual amount of minerals stored in the mineral cartridge 140 based on the amount of minerals discharged sensed by the mineral discharge sensor 170. The controller 400 may determine whether the mineral water supply module 100 is abnormal based on whether minerals have been discharged.
In particular, when the user selects the supply of mineral water, the controller 400 may subtract the amount of minerals, which have been discharged, sensed by the mineral discharge sensor 170 from the residual amount of minerals stored in the mineral cartridge 140 and display the final residual amount of minerals through the display unit 500.
First, when the used mineral cartridge 140 has been replaced with a new mineral cartridge 140, the controller 400 may receive a signal indicating that the new mineral cartridge 140 has been installed and may display a predetermined initial display mode through the display unit 500. That is, the controller 400 may initialize the amount of minerals stored in the mineral cartridge 140 based on the installation signal of the mineral cartridge 140.
After the amount of minerals stored in the mineral cartridge 140 is initialized, the controller 400 may sense a mineral water supply signal input by a user, and may subtract the amount of minerals that have been discharged from the initial amount of minerals stored in the mineral cartridge 140 or a previous amount of minerals stored in the mineral cartridge 140 to calculate a residual amount of minerals stored in the mineral cartridge 140.
The controller 400 may display one predetermined display mode among a plurality of predetermined display modes based on the residual amount range of the minerals to provide information on the residual amount of the minerals to a user. The controller 400 may visually provide the range of residual amounts of minerals by brightening or dimming various figures, symbols, and letters indicating the residual amount of minerals.
Meanwhile, when the amount of minerals, which have been discharged, sensed by the mineral discharge sensor 170 does not change for a predetermined time, the controller 400 may determine that the mineral water supply module 100 has failed.
In the case where the mineral discharge sensor 170 is a flow sensor, the controller 400 may sense the amount of minerals discharged from the mineral supply pipe 110 for a predetermined time through the mineral discharge sensor 170 to sense whether the minerals have been discharged.
That is, upon receiving the mineral water generation signal, the controller 400 may open the mineral supply valve 130 for a predetermined time and may operate the pump 160. If the discharge of minerals is not sensed by the mineral discharge sensor 170 despite the opening of the mineral supply valve 130, the controller 400 may determine that the mineral water supply module 100 has failed.
If the flow rate of the minerals has not changed for a predetermined time although the mineral water generation signal is input, the controller 400 may determine that the mineral water supply module 100 is abnormal.
If the flow rate of the minerals has not changed for a predetermined time (e.g., N seconds) although the signal for generating the mineral water has been input for a predetermined number of times (e.g., N times), the controller 400 may sense whether the abnormal state of the mineral water supply module 100 has repeatedly occurred for a predetermined number of times (e.g., N times).
Accordingly, if the flow sensor does not continuously sense the flow rate of the minerals although the signal for generating the mineral water has been input a predetermined number of times (e.g., N times), the controller 400 may determine that the mineral water supply module 100 has failed and may notify a user thereof. That is, the controller 400 may inform the user that the mineral water supply module 100 must be checked through the display unit 500.
In the case where the mineral discharge sensor 170 is a pressure sensor, the controller 400 may sense a change in pressure in the mineral supply pipe 110 for a predetermined time through the mineral discharge sensor. That is, the pressure sensor may sense whether the pressure in the mineral water supply pipe 110 is changed for a predetermined time to determine whether the mineral water supply module 100 has failed.
The controller 400 may determine that the mineral water supply module 100 is abnormal when the pressure in the mineral supply pipe 110 is lower than the target pressure for a predetermined time or repeatedly occurs a predetermined number of times, the pressure in the mineral supply pipe 110 is not changed, or the pressure in the mineral supply pipe 110 is higher than the target pressure.
For example, the mineral water supply module 100 may be abnormal as follows. When the value sensed by the pressure sensor remains equal to or lower than the predetermined value for a predetermined time, it may be determined that water leakage has occurred from the mineral supply valve 130 or that the pump 160 has failed. Further, when the pressure in the mineral supply pipe 110 does not change or is higher than a predetermined value, it may be determined that the mineral supply pipe 110 is blocked, the mineral supply valve 130 is not opened due to a malfunction of the mineral supply valve 130, or the pump 160 has malfunctioned.
Hereinafter, a display mode for informing a user of a residual amount of minerals or an abnormal state of the mineral water supply module through the display unit will be described in detail with reference to fig. 4(a) - (c).
In fig. 4(a) - (c), in the display mode for displaying the residual amount of minerals, the range of the residual amount of minerals is displayed by gradually lightening or darkening the plurality of bars, and the abnormal state of the mineral water supply module is displayed by an additional display unit. However, as described previously, the display mode for displaying the residual amount of minerals may be implemented in various forms. Accordingly, the present invention is not limited thereto.
After the new mineral cartridge 140 is installed, the controller 400 may display the initial amount of minerals stored in the mineral cartridge 140 through the display unit 500 in the first display mode. That is, as shown in fig. 4(a), a plurality of bars may be brightened.
Accordingly, when the current amount of minerals is calculated according to the selection of mineral water by the user, the controller 400 may display a display mode corresponding to the current residual amount of minerals.
As shown in fig. 4(b), the residual amount of minerals can be visually displayed by brightening only one bar.
Further, when the mineral water supply module 100 has failed, as shown in fig. 4(c), the additional display unit may be illuminated to inform a user thereof.
Hereinafter, a method of displaying the residual amount of minerals in the mineral cartridge of the drinking water supply apparatus will be described in detail with reference to fig. 5.
First, as a method of displaying the residual amount of minerals in the mineral cartridge, a mineral cartridge replacement confirmation step (S100) of confirming whether the mineral cartridge 140 has been replaced may be performed.
Upon confirming that the mineral cartridge 140 has been replaced, an initial mineral amount display step of displaying an initial amount of minerals in the mineral cartridge 140 may be performed (S200). At this time, the initial amount of the minerals may be displayed on the display unit 500.
After the initial mineral amount display step (S200), a mineral water generation signal sensing step (S300) of sensing whether the generation of mineral water is selected by a user may be performed.
In case that the mineral cartridge 140 is not replaced, the mineral water generation signal sensing step (S300) may be performed in a state in which the amount of minerals in the previous step is displayed.
When the user selects the production of mineral water, a mineral discharge sensing step (S400) may be performed: the discharge of minerals to the mineral supply pipe 110 is sensed using a mineral discharge sensor 170 disposed in the mineral supply pipe 110.
Subsequently, a residual amount calculating step (S500) may be performed: the controller 400 subtracts the amount of minerals that have been discharged, sensed by the mineral discharge sensor 170, from the amount of minerals in the previous step to calculate the current residual amount of minerals.
The controller 400 may compare the residual amount of the minerals calculated in the residual amount calculation step (S500) with a plurality of predetermined mineral residual amount ranges to select the corresponding mineral residual amount range.
Further, one of the plurality of display modes set to correspond to the mineral-remaining-amount range may be selected.
Specifically, the residual amount range selecting step (S600) may be performed: a predetermined residual mineral amount range corresponding to the amount of the mineral is selected from the predetermined residual mineral amount ranges.
Subsequently, a residual amount display step (S700) may be performed: the display mode corresponding to the selected residual amount range is displayed on the display unit 500.
When the amount of the mineral being measured is equal to or greater than the first reference amount, as shown in fig. 5, a second display mode may be performed. Here, the first reference amount may be less than an initial amount of the minerals stored in the mineral cartridge.
When the measured amount of the minerals is less than the first reference amount and equal to or greater than the second reference amount, a third display mode may be displayed. When the measured amount of the minerals is less than the second reference amount and equal to or greater than the third reference amount, a fourth display mode may be displayed.
When the measured amount of minerals is less than the third reference amount and equal to or greater than the fourth reference amount, the display unit 500 may blink to inform the user that the amount of minerals stored in the mineral cartridge is minimized, and the mineral cartridge needs to be replaced. In this case, the user must replace the mineral cartridge.
When the measured amount of minerals is less than the fourth reference amount, the controller 400 may visually inform the user that mineral water cannot be produced. That is, the controller 400 may display a signal indicating that the mineral has been used up or the mineral cartridge must be replaced through the display unit 500. In addition, the controller 400 may control the mineral water supply module 100 not to generate mineral water.
These display modes are only examples given for convenience of description, and the present invention is not limited thereto.
After the display mode corresponding to the sensed residual amount of minerals is displayed, the procedure may return to the mineral cartridge replacement confirmation step (S100), and the subsequent steps may be repeatedly performed.
Meanwhile, when the discharge of minerals has not been sensed for a predetermined time in the mineral discharge sensing step (S400), the abnormal state sensing step (S800) may be performed: an abnormal state of the mineral water supply module is sensed.
When the flow rate of the mineral has not changed for a predetermined time (e.g., N seconds) in the abnormal state sensing step (S800), the controller 400 may sense whether the abnormal state of the mineral water supply module 100 has repeatedly occurred a predetermined number of times (e.g., N times).
Subsequently, when the flow sensor has not sensed the flow rate of the minerals although the signal for generating the mineral water has been input a predetermined number of times (e.g., N times), the malfunction notification step (S900) may be performed: it is determined that the mineral water supply module 100 has failed and a user thereof may be notified.
Therefore, in the drinking water supply apparatus 1 according to the present invention, it can be determined whether the mineral water supply module 100 is abnormal through the mineral discharge sensor 170, whereby an additional device for determining an abnormal state of the mineral water supply module 100 may not be required.
Further, it is possible to inform the user that the mineral water supply module 100 is abnormal through the display unit, whereby appropriate follow-up measures can be taken.
As apparent from the above description, according to the present invention, it is possible to provide a drinking water supply apparatus capable of displaying the residual amount of minerals in a mineral cartridge so that a user can easily recognize the time when the mineral cartridge should be replaced.
In addition, according to the present invention, it is possible to provide a drinking water supply apparatus capable of rapidly sensing a malfunction of a mineral water supply module and appropriately taking follow-up measures.
Further, according to the present invention, it is possible to provide a drinking water supply apparatus capable of visually notifying a user of a residual amount of minerals or a malfunction of a mineral water supply module, thereby improving usability of the drinking water supply apparatus.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
