FIG. 2 shows an embodiment of the mineral eluting apparatus of FIG. 1. FIG. 2, the mineral eluting apparatus 100a includes an inlet 111 filled with a mineral eluting material and a purified water introduced therein, and an outlet 111 through which the purified water flowing through the inlet 111 passes through the mineral eluting material, And a receiving portion 110a having a discharge port 112 formed therein.

The mineral eluting apparatus 100 further includes a purified water supply pipe 171 for supplying purified water to the inlet 111 and a bypass pipe 173 for allowing the purified water to bypass the receiving unit 110a . At this time, the purified water guided through the bypass pipe (173) merges with the mineral water discharged through the discharge port (112). At least one valve for regulating the amount of purified water supplied through at least one of the purified water supply pipe 171 and the bypass pipe 173 may be provided. Hereinafter, the flow rate of the purified water or the mineral water controlled through the valve is defined to include the case where the valve is closed, that is, the case where the flow rate is zero.

The at least one valve may include a first valve V1 and a second valve 121 for adjusting the amount of purified water supplied through the purified water supply pipe 171 and a second valve V2 and 122 for controlling the amount of purified water supplied through the bypass pipe 173. [ ).

The bypass pipe 173 may be branched from the purified water supply pipe 171 and may include a third valve V3 and 123 for controlling the amount of purified water. When the third valve 123 is opened, the purified water is supplied to the second valve 122.

On the other hand, at least one of the first valve 121 and the second valve 122 can control the amount of purified water. The first valve (121) and / or the second valve (122) may be configured so that two or more outlets having different discharge flow rates are formed and selectively discharge the purified water through each outflow port. Alternatively, To adjust the water discharge amount.

In either case, the high-flow rate or low-flow rate constant can be selectively discharged through the first valve 121 and / or the second valve 122 under the control of the controller 156.

The mineral water discharge pipe 172 is connected to the discharge port 112 of the receiving portion 110a to guide the mineral water. The mineral water discharge pipe 172 can be joined to the bypass pipe 173 in the collecting pipe 174. [

The control unit 156 controls the first valve 121, the second valve 122 and the third valve 123 so that the purified water supplied to the receiving unit 110a and the purified water supplied to the receiving unit 110a, And the mineral content in the mineral water collected in the collecting pipe 174 is finally adjusted.

The mineral contents in the mineral water collected in the collecting pipe 174 according to the control method of the first valve 121, the second valve 122 and the third valve 123 are summarized.

Selection mode Valve control Mineral content Regular integer Mode 1 V1 block - V2 High flow rate V3 Opening Number of minerals Mode 2
V1 Low flow rate handful V2 Low flow rate V3 Opening Mode 3 V1 High flow rate much V2 - V3 block Mode 4 V1 Variable flow control variable V2 Variable flow control V3 Opening

As shown in Table 1, the mineral content setting unit 161 may provide at least one of mode 1, mode 2, mode 3, and mode 4.

In mode 1, the controller 156 controls the first valve V1 to shut off and the second valve V2 and the third valve V3 to open High flow rate). Accordingly, the supply of purified water to the accommodating portion 110a is blocked, and the purified water flows only through the bypass pipe 173. [ Table 1 shows that the high-flow rate constant is supplied through the second valve V2, but it is not necessarily limited to this, and it is also possible that the low-flow rate constant is controlled to be supplied.

Modes 2 to 3 are for generating mineral water through the mineral eluting apparatus 100a.

When the mode 2 is selected, the control unit 156 opens the third valve V3 so that the mineral water having a small mineral content can be generated. The third valve V3 is opened and the low flow rate V2 through the first valve V1 and the second valve V2, Can be controlled to be discharged.

When the mode 3 is selected, the controller 156 controls the third valve V3 to shut off and the first valve V1 to discharge the constant of the high flow rate so that a mineral content having a large mineral content can be generated.

Mode 4 is provided for finely controlling the mineral content, and it is possible to control the increase or decrease of the mineral content. In response to this, the control unit 156 controls the amount of mineral content to be discharged through the first valve V1 and / or the second valve V2 Thereby controlling the flow rate of the purified water.

The control unit 156 controls the amount of the mineral water to be supplied to the purified water supply pipe 171 from the purified water pipe 171 and the bypass pipe 173, So that the ratio of the amount of the purified water to be transferred is higher than the present state. For example, when the current state is set so that the first valve V1 is to discharge a low-flow rate purified water, the high-flow rate constant can be switched to discharge. Alternatively, it is also possible that the purified water amount discharged through the second valve V2 is controlled to be reduced. For example, if the current state is set so that the second valve V2 is to discharge an integer of a high flow rate, it can be switched to discharge the constant of a low flow rate.

The control unit 156 controls the amount of the mineral contained in the purified water supplied from the purified water supply pipe 171 through the purified water supply pipe 171 and the bypass pipe 173 through the purified water supply pipe 171 So that the proportion of the transferred purified water is controlled to be lower than that in the present state. For example, when the present state is set so that the first valve V1 is to discharge an integer of a high flow rate, it can be switched to discharge the constant of a low flow rate. Alternatively, it is also possible that the purified water amount discharged through the second valve V2 is controlled to be increased. For example, if the current state is set so that the second valve V2 discharges a low flow rate purified water, it can be switched to discharge a high flow rate constant.

A check valve 119a for blocking the reverse flow of the mineral water that is conveyed to the collecting pipe 174 after passing through the receiving portion 110a and a check valve 119a for bypassing the receiving portion 110a to return the purified water conveyed to the collecting pipe 174 A check valve 119b for shutting off the refrigerant may be provided.

Alternatively, the switching between the second mode and the third mode may be performed by increasing or decreasing the mineral content through the mineral content setting unit 161 according to the embodiment. That is, if the mineral content is set to increase or decrease more than the current set value, the controller 156 may control the mode to be changed. For example, if an increase in mineral content is set through the mineral content setting unit 161 in a state where the current mode is set, the controller 156 may control the valves according to the third mode. On the contrary, if the decrease of the mineral content is set through the mineral content setting unit 161 in the state where the third mode is currently set, the controller 156 may control the valves according to the second mode.

Fig. 4 (a) shows the position of the discharge port of the containing portion filled with minerals and FIG. 4 (b) shows the mineral content (TDS, total dissolved solids) included in the discharged water according to the position of each discharge port It is.

3, the mineral eluting apparatus 100b includes an inlet 111 filled with a mineral eluting material and filtered by the filter, and a raw water introduced through the inlet 111, And includes valves 132 and 133 for selectively interrupting the plurality of outlets 112 and 113. The accommodating portion 110b is formed with a plurality of outlets 112 and 113 formed to be sequentially discharged in accordance with the level during passage can do.

3, the first outlet 112 is formed at a lower level than the second outlet 113 and the first valve V1 132 is for controlling the amount of mineral water discharged from the first outlet 112 . When the first valve 132 is opened, the mineral water can be discharged through the first mineral water discharge pipe 172a.

The second valve (V2, 133) is for regulating the amount of mineral water discharged from the second outlet (113). When the second valve 133 is opened, the mineral water is discharged through the second mineral water discharge pipe 172b.

The first mineral water discharge pipe 172a and the second mineral water discharge pipe 172b are not necessarily formed independently of each other and the first mineral water discharge pipe 172a and the second mineral water discharge pipe 172b may be formed separately from each other by the intermittent operation of the first valve 132 or the second valve 133 (The first valve opening) or the high concentration (the second valve opening).

The third valve V3 131 is a valve for interrupting the raw water flowing into the inlet 111. When the third valve 131 is opened, the purified water passing through the filter unit 10 flows into the receiving portion 110b do.

According to the experiment, as the height of the outlet is higher, that is, the mineral water discharged through the outlet formed at the point where the water level in the receiving portion is higher, the mineral content is higher in the predetermined time (T <Ta) after the elution of the mineral starts And it was found. That is, in FIG. 4, the mineral content of the mineral discharged through the outlet of the location A is the highest, and the mineral content is decreased in the order of the location B and the location C, respectively. At this time, the mineral content was compared based on the total dissolved solids (TDS) value measured by the hardness sensor.

Based on these results, in this embodiment, by controlling the first valve 132 and the second valve 133 according to the mineral content set through the mineral content setting unit 161, the number of minerals discharged from the receiving unit 110b To control the minerals content.

When the increase of the mineral content is set through the mineral content setting unit 161 in the state where any one of the plurality of the outlets 112 and 113 is opened, the control unit 156 controls the first outlet (V2 opening) of the second outlet 113 disposed at a higher water level than the first outlet 112, the mineral content of the raw water discharged from the receiving portion 110b can be adjusted to increase. At this time, although the second outlet 113 may be opened while leaving the first outlet 112 as it is, according to an embodiment, when the second outlet 113 is opened, the first outlet 112 May be controlled to be cut off (V1 cutoff).

On the contrary, when at least one of the plurality of outlets is opened and the decrease of the mineral content is set through the mineral content setting unit 161, the control unit 156 controls the second outlet 113 to be opened By opening the first outlet 112 at a low level (opening V1), the mineral content in the mineral water discharged from the receiving portion 110b can be adjusted to be reduced. At this time, it is preferable that the second outlet 113, which was originally opened, is cut off (V2 cut).

Fig. 5 is a graph showing the relationship between the amount of the mineral eluting material discharged from the receiving portion 110 "and the amount of the mineral eluting material discharged from the receiving portion 110 " in the case where one kind of mineral eluting material is filled in the receiving portion, (TDS) in mineral water according to time.

Referring to FIGS. 1 to 5, two or more kinds of mineral eluting materials having different solubilities for water may be filled in the receiving portion 110 of the mineral eluting apparatus 100. Such a dissimilar mineral eluting apparatus can be filled in layers in the accommodating portions 110, 110a and 110b. At this time, it is preferable that the mineral eluting material filled in the upper part of the accommodating part 110, 110a, 110b has higher solubility in water than the different mineral eluting material filled in the lower part. For example, a material such as SiO2, calcium sulfite or a ceramic ball (tourmaline ball, far infrared ray ball, antibacterial ball) having a relatively low solubility in water is filled in the lower part of the receptacle 110, 110a and 110b, CaSO4 (calcium sulphate) or coral sand with high solubility in water can be filled.

Likewise, the upper portions of the receiving portions 110, 110a, May be filled with the composition. In this case, too, the solubility of the composition filled in the upper part must be higher than that of the composition filled in the lower part. Under these conditions, for example, SiO2, calcium sulfite or ceramic balls (tourmaline ball, A ball, and an antibacterial ball), and a composition in which CaSO4 (calcium sulfate) and a chalcogen sand are mixed may be filled thereon.

As can be seen from the graph (b) of FIG. 5, when one type of mineral leaching material is filled in the receiving portion 110 ', compared to the case (C) ') Has little change in mineral content over time. This means that even if the mineral eluting apparatus is used for a long time, the mineral content of the generated mineral water can be maintained at a certain level.

Meanwhile, when a different kind of mineral leaching material is filled in the receiving portion 110b shown in FIG. 3, an outlet may be formed corresponding to each layer. For example, in the case where calcium sulfite is filled in the lower part of the storage part 110b and the calcium sulfate is filled in the lower part of the storage part 110b (see FIG. 5), the first discharge port 112 is filled with calcium sulfite And the second outlet 113 may be formed in a section filled with calcium sulfate.
