In general, a drinking water supply device refers to a device for supplying drinking water to a user. This drinking water supply device may be an independent device, and it is also possible to form a part of home appliances such as a refrigerator.

The drinking water supply device can not only supply drinking water at room temperature, but also cool the drinking water flowing inside the drinking water supply device by using a cold water supply device including a refrigeration cycle or heat the drinking water with a heater so as to cool or hot water as needed. can also be supplied with

The drinking water may be ground water or raw water supplied from a tap water plant, or may be purified water obtained by filtering raw water supplied to the tap water plant by a separate filtering means. However, drinking water described below is meant to encompass drinkable water and is not limited to the above-mentioned types of water.

[0003] Recently, a drinking water supply device aims not only to provide filtered purified water or cold and hot water to users, but also to provide functional water tailored to the various needs of users. For example, a drinking water supply device having a mineral water supply module may be provided to provide a user with mineral water containing a predetermined amount of minerals.

Minerals are one of the five essential nutrients along with proteins, fats, carbohydrates and vitamins and are known to play an important role in biochemical (catalytic) action in the human body, as well as in the composition of bones and teeth.

In particular, elements such as calcium (Ca), potassium (K), magnesium (Mg), and sodium (Na) are sufficient in trace amounts, but are essential mineral elements for metabolism.

Mineral water containing these minerals can play an auxiliary role in improving health, such as discharging waste products accumulated in the body and promoting digestion.

In addition, when a predetermined amount of minerals are contained in drinking water, the user can feel a more improved water taste when drinking.

In order to generate such mineral water, an electrolysis device, a mineral filter, or a mineral water supply module for directly supplying liquid minerals to purified water through a mineral container containing concentrated minerals and a mineral supply pipe may be applied to the drinking water supply device.

In the case of the mineral water supply module, it can be implemented in a compact size compared to other devices, and has the advantage of being able to control the mineral outflow for generating mineral water.

The mineral container may be formed in a size and shape that are easily installed in a drinking water supply device. In addition, a predetermined amount of minerals corresponding to a set number of outflows of minerals for generating mineral water or a reference mineral water production amount may be accommodated in the mineral container.

In order to supply such mineral water, a pump that applies compressed air to the mineral container is used. Due to the pressure increased by the pump, a problem such as splashing of minerals occurs when the mineral container is replaced.

An object of the present invention is to provide a drinking water supply device capable of preventing leakage of minerals to the outside when a mineral container is exchanged, and a method for controlling the same.

In order to achieve the above object, the present invention is provided with a first valve for opening and closing the flow path, a first flow path for guiding drinking water; a water outlet passage connected to a rear end of the first passage to discharge the drinking water; A connection pipe connecting the first flow path and the water outlet flow path; A second flow path equipped with a second valve supplying minerals toward the connection pipe and opening and closing the flow path; a mineral container connected to the connection pipe through the second flow path and disposed in front of the second valve to accommodate concentrated minerals; a pump providing compressed air pressurized inside the mineral container to discharge the concentrated mineral to the outside of the mineral container; a third flow path connecting the pump and the mineral container to guide compressed air generated by the pump to the mineral container; a third valve provided in the third passage to selectively release pressure in the third passage; and a control unit controlling the third valve to release the pressure of the third flow path from the third valve.

The controller may operate the third valve after stopping the driving of the pump.

When the input unit receives an input indicating that the mineral container is mounted, the controller may close the third flow path from the outside using the third valve.

The control unit may drive the pump after sealing the third flow path by the third valve.

When receiving an input that the mineral container is detached from the input unit, the control unit may close the second flow path with the second valve.

In addition, the present invention comprises the steps of receiving an input signal from the input unit of the mineral container for supplying concentrated minerals to mix with drinking water; and when a signal that the mineral container is detached is input, a pump connected to the mineral container and applying pressure by compressed air is turned off, and then a third flow path connecting the pump and the mineral container is communicated with the outside, It provides a control method for a drinking water supply device comprising the steps of opening a passage of a third valve for releasing pressure in the third passage.

The method may further include sealing the third flow path from the outside by sealing the flow path of the third valve when a signal indicating that the mineral container is mounted is input.

After the passage of the third valve is closed, it is possible to turn on the pump.

The method may further include sealing the passage with a second valve disposed on the passage discharged from the mineral container when a signal indicating that the mineral container is attached or detached is input.

According to the present invention, since the pressure applied to the mineral container is released when the mineral container is exchanged, splashing of the minerals contained in the mineral container due to the high pressure can be prevented.

The third valve 510 does not open and close the third flow path 500 , but controls a flow path through which the third flow path 500 communicates with the outside of the third flow path 500 . That is, when the third valve 510 opens the flow path, the third flow path 500 can communicate with the outside, and when the third flow path 510 closes the flow path, the third flow path 500 sealed from the outside.

Minerals supplied from the mineral supply module 100 to the connection pipe 120 may be highly concentrated minerals.

In addition, the amount of minerals supplied from the mineral supply module 100 to the connection pipe 120 may be an important factor in determining the taste of the mineral water discharged through the cork 73.

At this time, the amount of minerals supplied from the mineral supply module 100 to the connection pipe 120 may be extremely small compared to the flow rate of drinking water (ie, purified water, hot water or cold water) flowing through the connection pipe 120. have.

Accordingly, the micro-passage portion 121 may be provided in the connection pipe 120 . That is, concentrated minerals may be supplied to drinking water flowing into the connection pipe 120 through the micro-passage part 121 .

For example, the connection pipe 120 may be formed in a “T” shape.

Hereinafter, with reference to FIG. 3 , a specific configuration of the mineral supply module 100 and a structure in which minerals are supplied from the mineral supply module 100 toward the water outlet pipe 70 will be described in detail.

3 is a view schematically showing the configuration of a mineral supply module according to an embodiment of the present invention.

Hereinafter, for convenience of description, the reference numeral 74 denoted as a cock valve above denotes a first valve.

2 and 3 together, the drinking water supply device 1 according to an embodiment of the present invention includes a water outlet pipe 70 configured to flow drinking water, a flow sensor 75 configured to detect the flow rate of the drinking water, and the water outlet A connection pipe 120 providing a mineral supply passage toward one side of the pipe 70, a second passage 110 formed to supply minerals toward the connection pipe 120, and a mineral container 140 containing concentrated minerals. , a pump 160 formed to pressurize the mineral container 140, and a third flow path 510 connecting the mineral container 140 and the pump 160.

The water outlet pipe 70 may include a first flow path 71 and a water outlet flow path 72 . At this time, the first flow path 71 may be provided on an upstream side compared to the water outlet flow path 72 .

Specifically, the first flow path 71 may be formed to allow drinking water to flow, and a first valve 74 formed to selectively open and close the first flow path 71 may be provided in the first flow path 71. can

The flow sensor 75 may be configured to detect the flow rate of drinking water flowing through the water outlet pipe 70 . More specifically, the flow rate sensor 75 may be formed to sense the flow rate of drinking water flowing through the first flow path 71 in real time.

The flow sensor 75 may be provided in the purified water pipe 30 at the rear end of the filter unit 20 or may be provided in the first flow path 71 . That is, the flow sensor 75 may be provided in a pipe or flow path provided upstream of the connection pipe 120 to sense the flow rate of drinking water.

The water outlet passage 72 may be formed to be connected to the rear end of the first passage 71 to discharge drinking water. That is, drinking water may be discharged through the cock 73 by sequentially flowing through the first flow path 71 and the water outlet flow path 72 .

The connection pipe 120 may be formed to connect the first flow path 71 and the water outlet flow path 72 .

At this time, the connection pipe 120 may be formed in a “T” shape, and the mixing pipe 122 and the warming pipe guide the drinking water passing through the first passage 71 to the water outlet passage 72. A micro-passage portion 121 may be provided to form a flow path of concentrated minerals toward the mixing pipe 122 in a direction perpendicular to the direction 122 .

When the concentrated mineral is guided to the mixing pipe 122, the pressure of the concentrated mineral may drop while passing through the micro-passage part 121.

A cross-sectional diameter of the micro-channel portion 121 may be smaller than a length of the micro-channel portion 121 . In addition, the cross-sectional area of the micro-passage portion 121 may be smaller than that of the mixing pipe 122 .

Accordingly, the amount of concentrated minerals guided toward the mixing pipe 122 can be precisely controlled.

The second flow path 110 may be formed to supply minerals (eg, concentrated minerals) toward the connection pipe 120 . That is, the second passage 110 may be formed as a mineral supply pipe (or a mineral supply passage).

One end of the second passage 110 in the longitudinal direction may be connected to the connection pipe 120 . More specifically, one end of the second flow path 110 in the longitudinal direction may be connected to the micro flow path portion 121 of the connection pipe 120 .

Accordingly, the supply pressure of the concentrated minerals supplied through the second flow path 110 may be lowered by the micro flow path part 121 . That is, the micro-passage part 121 functions to lower the supply pressure of the concentrated minerals supplied through the second flow-path 110 .

In addition, a second valve 130 may be provided in the second passage 110 . The second valve 130 is formed to selectively open and close the second flow path 110 .

The mineral container 140 may be formed to accommodate concentrated minerals. Also, the mineral container 140 may be formed to be connected to the connection pipe 120 through the second flow path 110 .

That is, one longitudinal end of the second flow path 110 may be connected to the connection pipe 120 and the other longitudinal end of the second flow path 110 may be connected to the mineral container 140 .

The pump 160 may pressurize the inside of the mineral container 140 to discharge the concentrated minerals contained in the mineral container 140 to the outside of the mineral container 140 .

For example, the pump 160 may be formed as an air pump. That is, the pump 160 may be an air pump configured to suck in external air and inject the external air into the mineral container 140 .

Accordingly, the pump 160 may suck in external air and inject it into the mineral container 140 to increase the pressure in the mineral container 140 .

That is, when external air is injected into the mineral container 140 by driving the pump 160, the concentrated minerals accommodated in the mineral container 140 are converted into the mineral container ( 140) can be discharged out.

At this time, the concentrated minerals discharged out of the mineral container 140 may flow into the second flow path 110 and the pressure within the second flow path 110 may increase. Also, since the inside of the mineral container 140 and the second passage 110 are in communication with each other, the pressure within the mineral container 140 and the pressure of the second passage 110 may be the same.

The pump 160 is connected to the mineral container 140 through a third flow path 510, so compressed air generated by the pump 160 passes through the third flow path 510 to the mineral container 140. ) can be guided.

The third valve 500 communicating the third flow path 510 to the outside is provided in the third flow path 510 . The third valve 500 does not open and close the third flow path 510, but opens and closes a flow path through which the third flow path 510 communicates with the outside. Therefore, even if the third valve 500 closes the passage, the compressed air generated by the pump 160 is guided to the mineral container 140 .

In addition, an injection hole 141 for injecting external air into the mineral container 140 and a discharge hole 142 through which concentrated minerals are discharged from the mineral container 140 may be formed in the lower portion of the mineral container 140. can

Specifically, concentrated minerals accommodated in the mineral container 140 are directed downward of the mineral container 140 by gravity. In this case, since the injection hole 141 and the discharge hole 142 are formed below the mineral container 140, the airtightness of the mineral container 140 may be improved.

More specifically, the drinking water supply device 1 according to an embodiment of the present invention may further include a container fastening part 150 coupled to the mineral container 150 at a lower side of the mineral container 140 .

In this case, the injection hole 141 and the discharge hole 142 may be formed at a lower end of the container fastening part 150 .

In addition, the container coupling part 150 may include an air injection passage 143 communicating with the injection hole 141 and a mineral discharge passage 144 communicating with the discharge hole 142 .

At this time, the injection hole 141 may communicate with the inside of the mineral container 140 through the air injection passage 143, and the discharge hole 142 may communicate with the inside of the mineral container 140 through the mineral discharge passage 144 ( 140) may be in communication with the inside.

Since the pump 160, that is, the air pump is formed to inject air into the mineral container 140, the airtightness of the mineral container 140 is maintained in order to discharge a necessary amount of concentrated minerals from the mineral container 140. it is necessary to do

As described above, since the mineral container 140 is disposed above the container fastening part 150 and the injection hole 141 and the discharge hole 142 are provided at the lower end of the container fastening part 150, , the airtightness of the mineral container 140 may be improved.

In addition, an air filter 161 may be provided at an air inlet side of the pump 160 . The air filter 161 serves to control impurities included in the air injected into the mineral container 140 through the pump 160 . At this time, the air filter 161 may be formed of a hydrophobic member.

In addition, a check fitting or a check valve 163 may be provided in the connection line 162 connecting the pump 160 and the mineral container 140 (ie, the container fastening part 150).

The check fitting or check valve 163 prevents the reverse flow of minerals from the mineral container 140 toward the pump 160 . This is because when minerals flow back into the pump 160, the pump 160 may be damaged.

Meanwhile, the drinking water supply device 1 according to an embodiment of the present invention controls the first valve 74, the flow sensor 75, the second valve 130, the pump 160, and the third valve 500. It may further include a control unit 180 to.

The controller 180 may be electrically connected to the first valve 74, the flow sensor 75, the second valve 130, the pump 160, and the third valve 500.

Referring to FIG. 4 , a process of detaching the mineral container will be described.

First, the user may input a signal to detach the already mounted mineral container 140 through the input unit 4 (S10). The input unit 4 may be formed to enable input, such as a touch screen, or may include a button capable of inputting a predetermined signal.

When a signal to detach the mineral container 140 is input, the controller 180 turns off the pump 160 (S12). The pump 160 is driven when the pressure is lower than a predetermined pressure, and can remain stopped when the predetermined pressure is maintained. That is, the pump 160 maintains a constant pressure inside the mineral container 140. At this time, since the inside of the mineral container 140 and the third flow path 510 are connected to each other, the internal pressure and the The pressure of the third flow path 510 may be the same.

Since the pump 160 stops driving, additional compressed air is not supplied to the inside of the third flow path 510 and the mineral container 140, and the pressure increases while the mineral container 140 is removed. It doesn't work.

After the driving of the pump 160 is stopped, the controller 180 opens the passage of the third valve 500 (S14).

Since the third valve 500 selectively communicates the third flow path 510 to the outside, when the flow path is opened by the third valve 500, the third flow path 510 communicates with the outside. . Accordingly, the pressure increased by the pump 160 is lowered. That is, the internal pressure of the third flow path 510 and the mineral container 140 becomes equal to atmospheric pressure by the third valve 500 .

Accordingly, since the internal pressure of the mineral container 140 is equal to the atmospheric pressure even when the user separates the mineral container 140 , splashing of minerals from the mineral container 140 may be prevented.

Meanwhile, when a signal indicating that the mineral container is mounted is input in S10 , the second valve 130 closes the second flow path 110 and blocks movement of minerals in the second flow path 110 . In this case, it is possible to prevent the minerals from being randomly moved and being contaminated.

Referring to FIG. 5, a process of mounting the mineral container will be described.

The user may input a signal indicating that the mineral container 140 is mounted through the input unit 4 (S20).

When a related signal is input from the input unit 4, the control unit 180 closes the passage in the third valve 500 (S22). The third valve 500 does not seal the third flow path 510, but opens and closes the flow path communicating with the outside air at the portion where the third valve 500 is installed. Even if the third flow path 510 seals the flow path, the pump 160 and the mineral container 140 are connected to each other through the third flow path 510 .

And the control unit 180 can turn on the pump 160 (S24). The pump 160 may be adjusted so that a constant pressure is maintained inside the third flow path 510 and the mineral container 140 . Therefore, when the control unit 180 turns on the pump 160, the pump 160 is driven immediately, so that compressed air may not be moved to the mineral container 140.

For example, if the pressure of the mineral container 140 is maintained at a certain level even when the mineral container 140 is newly installed, the pump 160 may not generate compressed air at that time. On the other hand, when the user manipulates the lever 4 to discharge mineral water, the pressure inside the mineral container 140 decreases because the minerals are discharged from the mineral container 140 to the outside. In this situation, it is possible that the pump 160 is driven so that compressed air is moved to the mineral container 140 through the third flow path 510 .

The present invention is not limited to the above-described embodiments, and as can be seen from the appended claims, modifications can be made by those skilled in the art to which the present invention belongs, and such modifications fall within the scope of the present invention.
