Functional liquid mixing device

An embodiment of the functional liquid mixing device 100 according to the present invention includes a body 200, a functional liquid mixing member 300, a functional liquid supply unit 400, a supply amount control unit 500, and a control unit 600. Can include.

The body 200 may be provided with a functional liquid mixing member 300, a functional liquid supply unit 400, and a supply amount control unit 500, respectively. For example, as shown in FIGS. 1 and 2, the body 200 may include a first body 210 and a second body 220 connected to the first body 210. In addition, the first body 210 and the second body 220 are connected, so that at least a part of each of the functional liquid mixing member 300, the functional liquid supply unit 400, and the supply amount control unit 500 may be provided. Space can be formed. However, the configuration of the body 200 is not particularly limited, and any known configuration is possible as long as the functional liquid mixing member 300, the functional liquid supply unit 400, and the supply amount control unit 500 can each be provided. Do.

The functional liquid mixing member 300 may be provided in the body 200. For example, the functional liquid mixing member 300 may be provided on the body 200. However, the portion of the body 200 in which the functional liquid mixing member 300 is provided is not particularly limited, and may be provided on any portion of the body 200.

Water may flow into the functional liquid mixing member 300. For example, water and purified water filtered by the filter unit 20 included in the water purifier 10 to be described later may be introduced into the functional liquid mixing member 300. However, the water flowing into the functional liquid mixing member 300 is not particularly limited, and any water may be used.

When there is no supply of the functional liquid to the functional liquid mixing member 300 through the functional liquid supply unit 400, as shown in FIG. 4 and will be described later, the water flowing into the functional liquid mixing member 300 It may be discharged as it is by flowing the liquid mixing member 300. In this way, water, such as purified water, discharged from the functional liquid mixing member 300 may be supplied to the user.

In addition, the water introduced into the functional liquid mixing member 300, as shown in Figure 5 and will be described later, when there is supply of the functional liquid to the functional liquid mixing member 300 through the functional liquid supply unit 400 , As the functional liquid mixing member 300 flows, it becomes functional water after being mixed with the supplied functional liquid, and may be discharged from the functional liquid mixing member 300. In this way, the functional water discharged from the functional liquid mixing member 300 may be supplied to the user. The functional water obtained by mixing the functional liquid and water flowing through the functional liquid mixing member 300 may be, for example, mineral water or vitamin water. However, the functional water is not particularly limited, and any known functional water may be used as long as it is a functional water obtained by mixing water and a functional liquid.

A venturi flow path 310 may be formed in the functional liquid mixing member 300. The venturi flow path 310 may have a narrow cross-sectional area and then widen. Thereby, water and a functional liquid can be mixed. That is, when water flows into the venturi passage 310 and flows through the portion of the venturi passage 310 whose cross-sectional area is narrowed, the flow velocity gradually increases and the pressure gradually decreases, and the neck portion of the venturi passage 310 with a minimum cross-sectional area. At (311) the flow rate is maximum and the pressure can be minimum. Accordingly, the pressure of the venturi flow path 310 may be lower than the pressure of the flow path connected to the venturi flow path 310, for example, the pressure of the functional fluid flow path 340 that will be described later connected to the venturi flow path 310, and a pressure difference may occur. And, due to such a pressure difference, a venturi effect of allowing the functional liquid of the functional liquid flow path 340 to flow into the venturi flow path 310 may occur. In this way, the functional liquid flowing into the venturi flow path 310 by the Venturi effect may be mixed with water flowing through the venturi flow path 310 to become a functional water such as mineral water or vitamin water.

The functional liquid mixing member 300 may further include an inlet flow path 320, a discharge flow path 330, and a functional liquid flow path 340.

The inflow passage 320 may be connected to the filter unit 20 of the water purifier 10 to be described later by, for example, a water supply line LP to be described later. Thereby, water filtered by the water purification filters 21, 22, and 23, which will be described later, included in the filtering unit 20, that is, purified water may be introduced into the inflow passage 320 and flow. In addition, the inflow passage 320 may be connected to one side of the venturi passage 310. Accordingly, the water flowing through the inflow passage 320 may flow into the venturi passage 310 and flow through the venturi passage 310.

The discharge flow path 330 may be connected to the other side of the venturi flow path 310. Thereby, the water flowing through the venturi flow path 310 without mixing with the functional liquid or the functional water mixed with the functional liquid while flowing through the venturi flow path 310 flows through the discharge flow path 330 and then the functional liquid mixing member It can be discharged from 300. Fitting members FT1 and FT2 and sealing members SL are connected to the discharge flow path 330 as shown in FIGS. 2 and 3 to connect a discharge pipe (not shown), and the like.

The functional fluid may flow into the functional fluid flow path 340. For example, the functional liquid flow path 340 may be connected to a functional liquid supply unit 400 connected to a functional liquid supply source as described later. In addition, due to the Venturi effect of the venturi flow path 310 described above, the functional liquid of the functional liquid supply source may flow into the functional liquid flow path 340 through the functional liquid supply unit 400. The functional liquid flow path 340 may be connected to the venturi flow path 310 or the discharge flow path 330, for example, a portion of the discharge flow path 330 connected to the venturi flow path 310. Thereby, the functional fluid flowing through the functional fluid flow path 340 is a discharge flow path connected to the Venturi flow path 310 or the Venturi flow path 310 as shown in FIG. 5 by the Venturi effect of the Venturi flow path 310 It is introduced into a portion of 330 and may be mixed with water flowing through the venturi passage 310 or a portion of the discharge passage 330 connected to the venturi passage 310.

The functional liquid supply unit 400 may be provided on the body 200 to be connected to the functional liquid supply source and the functional liquid mixing member 300. Thereby, by the Venturi effect of the venturi flow path 310 of the functional liquid mixing member 300 described above, as shown in FIG. 5, the functional liquid of the functional liquid supply source is transmitted through the functional liquid supply unit 400. It may be supplied to the mixing member 300.

The functional liquid supply source to which the functional liquid supply unit 400 is connected may be, for example, a functional liquid storage container VF in which the functional liquid is stored, as shown in FIG. 6. However, the functional liquid supply source is not particularly limited, and any known one may be used as long as the functional liquid supply unit 400 is connected to supply the functional liquid to the functional liquid supply unit 400. The functional liquid stored in the functional liquid supply source may be a highly concentrated liquid. Accordingly, even if a relatively small amount of functional liquid is mixed with water, since functional water in a predetermined concentration range can be produced, the functional liquid supply source such as the functional liquid storage container (VF) described above and the functional liquid according to the present invention are mixed. The size of the device 100 can be made smaller.

The functional liquid supply unit 400 may include a functional liquid supply pipe 410. One side of the functional liquid supply pipe 410 may be connected to a functional liquid supply source. Accordingly, the functional liquid of the functional liquid supply source is introduced into one side of the functional liquid supply pipe 410 due to the Venturi effect of the venturi flow path 310 of the functional liquid mixing member 300 described above, and passes through the functional liquid supply pipe 410. It can flow. For example, the functional liquid supply unit 400 may further include a supply source connection member 430 as shown in FIGS. 1 to 3. In addition, one side of the functional liquid supply pipe 410 is connected to the supply source connection member 430 and the supply source connection member 430 is connected to a functional liquid supply source such as the functional liquid storage container (VF) described above, and the functional liquid supply pipe 410 One side of) may be connected to the functional liquid supply source. However, the configuration in which one side of the functional liquid supply pipe 410 is connected to the functional liquid supply source is not particularly limited, and any known configuration may be used.

The other side of the functional liquid supply pipe 410 may be connected to the functional liquid flow path 340 of the functional liquid mixing member 300. Accordingly, the functional liquid flowing through the functional liquid supply pipe 410 may be introduced into the functional liquid flow path 340 of the functional liquid mixing member 300 and flow.

The functional liquid supply pipe 410 may be a flexible pipe. Accordingly, more easily, the functional liquid may not flow or flow through the functional liquid supply pipe 410, and the amount of the functional liquid flowing through the functional liquid supply pipe 410 can be adjusted.

If a part of the functional liquid supply pipe 410, which is a flexible pipe, is not pressed, the functional liquid supply pipe 410 may be completely opened. In addition, a part of the functional liquid supply pipe 410 may be pressed so that the functional liquid supply pipe 410 is completely closed as shown in FIG. 4. Accordingly, the functional liquid may not flow through the functional liquid supply pipe 410. In this case, even if the Venturi effect by the Venturi flow path 310 of the functional liquid mixing member 300 occurs, the functional liquid of the functional liquid supply source is supplied to the functional liquid mixing member 300 through the functional liquid supply pipe 410 It will not be. On the other hand, by adjusting the degree to which a part of the functional liquid supply pipe 410 is pressed, the degree of opening of the functional liquid supply pipe 410 is adjusted, so that the amount of the functional liquid flowing through the functional liquid supply pipe 410 can be adjusted.

The functional liquid supply unit 400 may further include a check valve 420. The check valve 420 may be connected to the functional fluid flow path 340 and the functional fluid supply pipe 410 of the functional fluid mixing member 300. In addition, it is possible to prevent the water or the functional liquid in the functional liquid mixing member 300 from flowing back into the functional liquid supply pipe 410.

The check valve 420 may include a valve body 421, an opening/closing member 422, and an elastic member 423, as shown in FIGS. 2 and 3.

One side of the valve body 421 may be connected to the functional liquid supply pipe 410. Accordingly, the functional liquid flowing through the functional liquid supply pipe 410 may flow into the valve body 421. An opening/closing hole 421a may be formed in the valve body 421. The other side of the valve body 421 may be connected to the functional fluid flow path 340 of the functional fluid mixing member 300. Accordingly, the functional liquid passing through the opening/closing hole 421a of the valve body 421 may be introduced into the functional liquid flow path 340 of the functional liquid mixing member 300. The valve body 421 may be provided with a sealing member SL.

The opening/closing member 422 may be movably provided on the valve body 421 to open and close the opening/closing hole 421a of the valve body 421.

The elastic member 423 may be provided on the valve body 421 so as to apply an elastic force to the opening and closing member 422 in a direction of closing the opening and closing hole 421a of the valve body 421. Accordingly, only when the force generated by the Venturi effect by the Venturi flow path 310 of the functional liquid mixing member 300 is greater than the elastic force of the elastic member 423, the opening and closing member 422 in the direction of opening the opening and closing hole 421a. ) Can move. And, the force generated by the venturi effect of the venturi flow path 310 of the functional liquid mixing member 300 is less than the elastic force of the elastic member 423, or the water does not flow through the functional liquid mixing member 300 When the Venturi effect by 310 does not occur, the opening/closing member 422 may close the opening/closing hole 421a by the elastic force of the elastic member 423. Thereby, water or the functional liquid of the functional liquid mixing member 300 may not flow back to the functional liquid supply pipe 410.

The supply amount control unit 500 may be provided on the body 200 so as to be linked to the functional liquid supply unit 400. The supply amount control unit 500 allows the functional liquid of the functional liquid supply source not to be supplied or supplied to the functional liquid mixing member 300 through the functional liquid supply unit 400, and the amount of the supplied functional liquid can be adjusted. .

The supply amount control unit 500 may include a pressing member 510 and a driving motor 520. The pressing member 510 may be rotatably provided on the body 200 so as to press a part of the functional liquid supply pipe 410 of the functional liquid supply unit 400. The driving motor 520 may be connected to the pressing member 510 to rotate the pressing member 510.

As shown in Fig. 4, the pressing member 510 rotates by the driving motor 520 so that the functional liquid supply pipe 410 of the functional liquid supply unit 400 can be closed. A part of the supply pipe 410 may be pressed. Accordingly, even if the Venturi effect occurs by the Venturi flow path 310 of the functional liquid mixing member 300, the functional liquid of the functional liquid supply source is not supplied to the functional liquid mixing member 300 through the functional liquid supply pipe 410. I can't. In this case, the water introduced into the functional liquid mixing member 300 may be discharged from the functional liquid mixing member 300 without being mixed with the functional liquid while flowing through the functional liquid mixing member 300.

The pressing member 510 is rotated by the driving motor 520 so that the functional liquid supply pipe 410 of the functional liquid supply unit 400 is at least partially opened, so that the pressing member 510 is part of the functional liquid supply pipe 410 You can press or not. Accordingly, by the Venturi effect generated by the Venturi flow path 310 of the functional liquid mixing member 300, the functional liquid of the functional liquid supply source is the functional liquid supply pipe of the functional liquid supply unit 400 as shown in FIG. Through 410, it may be supplied to the functional liquid mixing member 300. Further, the water introduced into the functional liquid mixing member 300 may be mixed with the functional liquid while flowing through the functional liquid mixing member 300 to become functional water, and then discharged from the functional liquid mixing member 300. In this case, by adjusting the rotational position of the pressing member 510 by the driving motor 520, by adjusting the degree to which the pressing member 510 presses the functional liquid supply pipe 410 of the functional liquid supply unit 400, the function The degree of opening of the liquid supply pipe 410 can be adjusted. Accordingly, the amount of the functional liquid supplied to the functional liquid mixing member 300 through the functional liquid supply pipe 410 of the functional liquid supply unit 400 can be adjusted.

The control unit 600 controls the supply amount control unit 500, so that the water introduced from the functional liquid mixing member 300 is discharged as it is, or the functional water having a predetermined concentration range in the functional liquid mixing member 300 ) Can be discharged. The control unit 600 may allow the functional water of a predetermined concentration range to be discharged from the functional liquid mixing member 300 regardless of a change in the flow rate of water flowing into the functional liquid mixing member 300. For example, the control unit 600 may be electrically connected to the driving motor 520 of the supply amount control unit 500. Then, the control unit 600 rotates the pressing member 510 of the supply amount control unit 500 through the drive motor 520 of the supply amount control unit 500 to rotate the functional liquid supply pipe 410 of the functional liquid supply unit 400 It is possible to open/close or adjust the degree of opening of the functional liquid supply pipe 410.

The control unit 600 may be electrically connected, for example, to a flow sensor SF that measures the flow rate of water introduced into the functional liquid mixing member 300. As shown in FIG. 6, the flow sensor SF is connected to the filter unit 20 of the water purifier 10, and the water filtered by the filter unit 20, that is, to the purified water supply line LP through which purified water flows. It can be provided. However, the location where the flow sensor SF is provided is not particularly limited, and may be provided anywhere where the flow rate of water flowing into the functional liquid mixing member 300 can be measured.

When the flow rate of water flowing into the functional liquid mixing member 300 measured by the flow sensor SF increases, the controller 600 presses the member through the driving motor 520 so that the degree of opening of the functional liquid supply pipe 410 is reduced. You can rotate 510.

When the flow rate of water flowing into the functional liquid mixing member 300 increases, a pressure difference due to the Venturi flow path 310 of the functional liquid mixing member 300 may increase. In addition, since the amount of the functional liquid mixed with the water flowing through the functional liquid mixing member 300 increases, the concentration of the functional water discharged from the functional liquid mixing member 300 may be greater than a predetermined concentration range. In this case, the control unit 600 may rotate the pressing member 510 through the driving motor 520 so that the degree of opening of the functional liquid supply pipe 410 is reduced. Thereby, the amount of the functional liquid mixed with the water flowing through the functional liquid mixing member 300 is reduced, so that the concentration of the functional water discharged from the functional liquid mixing member 300 is within a predetermined range.

In addition, when the flow rate of water flowing into the functional liquid mixing member 300 measured by the flow sensor SF decreases, the control unit 600 uses the driving motor 520 to increase the degree of opening of the functional liquid supply pipe 410. The pressing member 510 can be rotated.

When the flow rate of water flowing into the functional liquid mixing member 300 decreases, the pressure difference due to the Venturi flow path 310 of the functional liquid mixing member 300 may decrease. In addition, since the amount of the functional liquid mixed with the water flowing through the functional liquid mixing member 300 is reduced, the concentration of the functional water discharged from the functional liquid mixing member 300 may be less than a predetermined concentration range. In this case, the control unit 600 may rotate the pressing member 510 through the driving motor 520 so that the degree of opening of the functional liquid supply pipe 410 is increased. Accordingly, the amount of the functional liquid mixed with the water flowing through the functional liquid mixing member 300 is increased, so that the concentration of the functional water discharged from the functional liquid mixing member 300 is within a predetermined range.

Functional liquid mixed with water flowing through the functional liquid mixing member 300 according to a change in the flow rate of water flowing into the functional liquid mixing member 300 so that the functional water discharged from the functional liquid mixing member 300 is within a predetermined concentration range The degree to which the control unit 600 rotates the pressing member 510 through the driving motor 520 so that the amount of is adjusted is determined by, for example, an experiment, and a memory unit (not shown) included in the control unit 600 Can be saved in.
