The drawings of the attached drinking water supply device illustrate exemplary forms of the present invention, which are provided to explain the present invention in detail, but the technical scope of the present invention is not limited thereto.

1, the drinking water supply device 1 can convert the raw water flowing into the drinking water supply device 1 through the external water supply source 10 into the purified water via the filter part 20. [ The configuration of the filter unit 20 can be variously modified, and the filter unit 20 can be configured through a plurality of single filters. In FIG. 1, three single filters are connected in series to form the filter unit 20, but the present invention is not limited thereto.

Specifically, the filter unit 20 may include a pre-carbon filter 21, a UF filter 22, and a post-carbon filter 23. Of course, other types of filters may be added in some cases.

The purified water is filtered and purified water can be discharged to the outside through the purified water pipe 30, the purified water supply valve 32 and the cock 73.

The drinking water supply device (1) can be supplied with cold water or hot water according to the demand of the user.

The hot water supplied by heating the purified water is supplied to the first branched water purification pipe 301 branched from point A of the purified water pipe 30, the heating device 51, the hot water pipe 50, the hot water supply valve 52, To be able to go out.

FIG. 1 shows an embodiment in which purified water, cold water and hot water are discharged through a single cock 73 for convenience of explanation. However, each of the corks for leaving the purified water, the cold water and the hot water may be provided, and the constitution of the cock for the outflow is not limited to the figure, since the single coke hot water may have separate coke.

On the other hand, a cock valve 74 may be provided at a rear end of the purified water supply valve 32, the cold water supply valve 42 and the hot water supply valve 52. The cock valve 74 may be connected to the distribution pipe 60. The distribution pipe 60 may be connected to the purified water pipe 30, the cold water pipe 40, and the hot water pipe 50, respectively.

An outflow pipe 70 to which purified water, cold water or hot water can be supplied may be provided at the rear end of the cock valve 74.

Therefore, purified water, cold water or hot water can be supplied to the distribution pipe 60. When the coke 73 is opened through the single coke valve 74, purified water, cold water or hot water is selectively supplied through the outflow pipe 70 .

On the other hand, the mineral water supply module 100 for generating mineral water may be connected to the outflow pipe 70.

The mineral water supply module 100 may be connected to one side of the outflow pipe 70 through a mineral water generator 120 connected to the outflow pipe 70.

Hereinafter, for convenience of explanation, an outflow pipe 70 positioned at the front end of the mineral water generation unit 120 and supplying purified water to the mineral water generation unit 120 is referred to as a water supply pipe 71, and a mineral water generation unit 120 (Hereinafter referred to as " discharge pipe 72 ").

That is, when the coke 73 is opened through the single coke valve 74, the water pipe 71 may be a pipe that selectively receives water, cold water or hot water and flows into the mineral water generating unit 120.

The discharge pipe 72 is a pipe through which water, cold water, hot water, or mineral water flowing in the mineral water generating unit 120 is selectively discharged to the coke 73 according to the user's selection.

The mineral water supply module 100 may include a mineral supply pipe 110 connected to the mineral water generation unit 120 to supply minerals.

 The mineral supply pipe 110 may be provided with a mineral supply valve 130 for selectively supplying minerals to the mineral water generating unit 120. And a mineral supply unit 180 including a mineral cartridge 140 containing a mineral concentrate and a pump 190 for discharging minerals by pressing the mineral cartridge 140.

Meanwhile, the minerals supplied from the mineral water supply module 100 to the mineral water generator 120 may be concentrated minerals at a high concentration.

The mineral cartridge 140 may contain a mineral concentrate mixed with minerals such as calcium (Ca), potassium (K), magnesium (Mg), and sodium (Na).

For example, the mineral concentration of the mineral concentrate contained in the mineral cartridge 140 may be about 200 times the average mineral concentration contained in the purified water.

According to the experimental results, the amount of the mineral concentrate required to produce the user's preferred mineral number of the taste is an extremely small amount of 0.0006 times the integer. In order to provide the mineral water having the water taste within the allowable deviation every time, it is required that a predetermined amount of the mineral is supplied for a predetermined time.

Therefore, a predetermined minute amount of minerals must be supplied constantly for a predetermined period of time, as described above, and the mineral water supply module 100 is required to provide a micro channel part 200 capable of supplying a minute amount of minerals.

The micro channel portion 200 may be formed in a cylindrical or polyhedral shape having a predetermined area and a predetermined length. The flow rate discharged from the micro channel section 200 may be determined by the area and the length if the pressure of the pump 190 to be pressurized is the same.

In order to supply a minute amount of minerals set for a predetermined time to the mineral water generating unit 120, the micro channel unit 200 is preferably formed to have a small flow cross sectional area and a predetermined length to induce a pressure loss of the liquid Do.

Specifically, when the micro channel portion 200 is formed in a cylindrical shape, the diameter may be in a range of 0.5 mm or more and 1.0 mm or less.

The maximum diameter of the micro channel portion 200 may be a diameter capable of supplying minerals within a predetermined allowable deviation range.

Specifically, it is preferable that the micro channel part 200 is formed to have a diameter such that the water or mineral water can be taken out within a tolerance of the tastes when the water is crossed.

That is, when the water is crossed with the mineral water, the minerals remaining in the micro channel part 200 can be minimized so that the purified water can be formed with a diameter allowing the mineral to be contained in an acceptable concentration range .

And when the mineral water crosses the water, the mineral water containing an acceptable concentration range of minerals can be formed in the diameter of the water.

It is most preferable that the minimum diameter of the micro channel portion 200 is formed to a diameter of 0.5 mm which enables molding or processing. A diameter of 0.5 mm or less is not easy to be formed or processed, and therefore, productivity may be deteriorated.

The maximum diameter of the micro channel portion 200 derived by the experiment and satisfying the above conditions may be 1.0 mm.

The numerical diameter of the micro channel portion 200 is a value derived from a water supply pipe having an outer diameter of 6.35 mm and a pump having a discharge flow rate of 0.1 ml / s to 1 ml / s, which is commonly used in the drinking water supply apparatus.

If the flow cross-sectional area of the micro channel portion 200 has a circular or polygonal shape other than a circle, it is most preferable that the micro flow channel portion 200 has a minimum machining area.

By forming the micro channel part 200 in a predetermined length range, it is possible to induce a pressure drop of minerals flowing through the micro channel part 200 and to discharge a preset amount of minerals. In addition, it is possible to reduce the influence of the pressure variable that may be generated by driving the pump 190.

Specifically, when the micro channel section 200 is formed at a lower limit value or less than a predetermined length range, a large amount of minerals may be discharged so that the pressure drop of the minerals flowing through the micro channel section 200 is small, . That is, when the micro channel portion 200 is formed short, the pressure of the minerals flowing in the mineral supply pipe 110 can not be sufficiently lowered due to the friction loss, so that the discharge flow rate may become a set value or more.

On the other hand, when the length of the micro channel part 200 is longer than the upper limit value of the predetermined length range, a pressure loss due to the friction of the minerals flowing in the micro channel part 200 is excessively generated, so that a smaller amount of mineral flow rate can be discharged.

Therefore, it is preferable that the micro flow path portion 200 is formed to have an appropriate length for discharging a fixed amount of minerals in a fixed amount. Specifically, the length of the micro channel portion 200 may be 15 mm or more and 20 mm or less.

First, the configuration of the mineral water supply module will be described in detail with reference to FIG.
