Description

water purifier

The present invention relates to a water purifier capable of adjusting the height or horizontal position of the water outlet nozzle.

In general, a water purifier is a device that filters water and supplies purified water from which impurities have been removed. The water purifier is widely used in home appliances and industries. In particular, the water purifier may be provided as a home water purifier that provides purified water that a user can consume.

The water purifier includes a water purifier main body on which a filter, etc. are mounted, and a water outlet that provides water filtered by the water purifier main body. Generally, the water outlet portion is fixedly disposed on the front of the water purifier main body. Accordingly, the user can take in purified water by placing a container for holding water in the water outlet.

Due to this structure, there is a problem in that user convenience is not secured because the location of the water outlet is restricted.

In addition, as living standards improve, the demand for water purifiers that can discharge water at high temperatures and receive water using containers of various heights is increasing, and as the demand for water purifiers related to this increases, the demand for water purifiers is also gradually increasing. Consumer interest in the hot water temperature and water outlet convenience of water purifier products is increasing and is recognized as an important factor in product selection, but it was found that the majority of products do not meet expected performance.

Although various technologies are being developed and applied to improve the convenience of using water purifiers, consumer demand is not decreasing, and the media is also raising issues about the dangers of hot water in water purifiers and the problem of water splashing into the water outlet nozzle and contaminating the water outlet nozzle. .

That is, in the past, the height of the water outlet nozzle through which purified water, hot water, cold water, etc. are dispensed was high, so there was a problem of water splashing when the water discharged due to a drop touched the cup.

Additionally, there was a risk of burns if hot water splashed when dispensing hot water. Additionally, there were problems such as water splashing and contaminating the surrounding area. Additionally, there was a problem that the location of the water outlet was limited.

Meanwhile, in the case of a water purifier in which the location of the water outlet is changed, the following prior art has been disclosed.

<Prior document 1>

1. Publication number: No. 10-2010-0054580 (Publication date: May 25, 2010)

2. Name of invention: Water purifier

The prior art document 1 discloses a water purifier in which, when the drive motor and the drive gear rotate, the cock moving gear rotates, the detachable gear unit moves up and down, and the coke unit coupled to the detachable gear unit moves up and down, thereby adjusting the height.

In addition, a rotation limiting means is provided on the cock body so that the detachable gear rotates only within a certain range, and the rotation limiting means includes a support spring, a fixed hook, and a rotation limiting groove, and the fixed hook is inserted into the rotation limiting groove to form a fixed hook. A feature in which the detachable gear rotates only within a certain range is disclosed.

In the case of the prior art as described above, in a structure where the water outlet nozzle moves up and down, the presence or absence of a container placed below the water outlet nozzle and the height of the container cannot be detected.

In addition, the water outlet nozzle is not structured to automatically rise and fall, and therefore, the technology for detecting the height of the water intake container placed below the water outlet nozzle, lowering it to the corresponding height, and then proceeding with water extraction is not disclosed.

In addition, there was a problem of insufficient space for deformation of the water outlet pipe due to the vertical movement of the water outlet nozzle in the narrow space inside the water outlet unit of the water purifier.

In addition, there was a problem that the water extraction process became cumbersome as the water extraction proceeded while the user directly manipulated the water extraction nozzle to be positioned at the height of the water extraction nozzle.

In addition, in the conventional case, it is difficult to detect the cup height by moving the two water discharge nozzles in the rotation direction of the motor (CW: left, CCW: right), and it is difficult to immediately respond to water discharge on the other side after fixing one water discharge nozzle. There was also a problem.

In addition, generally, when installing a water purifier at home, the installation location is determined by considering the space occupied by the water purifier and the space where the container can be placed. However, if the installation location is small, a problem may arise where there is not enough space to place the container even if the water purifier is installed.

To solve this problem, Korean Patent Registration No. 10-1770481 shows a structure in which the rotator is made up of a circle, and when the user touches the water outlet nozzle, the water outlet nozzle moves and the position of the water outlet nozzle changes.

However, in the case of this structure, while purified water is being dispensed from the water outlet into the container, there is a risk that the user may rotate the water outlet with unintentional force, resulting in water being dispensed at a location outside the container.

In addition, electrical components such as a control unit are generally placed in the water outlet of a water purifier, and especially when the water outlet is raised and lowered, parts such as a motor and gears are additionally placed. If electrical components are placed in the water outlet and the water discharged is structured to be detached from the water purifier main body, a problem occurs in which the water outlet module is easily removed from the main body due to the weight of the electrical components placed in the water outlet module.

Additionally, if the water outlet module is unintentionally removed and falls to the floor, the electrical components placed in the water outlet module may be damaged.

Additionally, when the user repeatedly attaches and detaches the water outlet by hand, contaminants such as bacteria and dust may enter the water purifier, causing a problem of poor hygiene.

The present invention was proposed to solve this problem, and provides a water purifier that automatically blocks the inflow of raw water to prevent water leakage when replacing the filter.

In addition, a water purifier is provided that automatically drains the water after replacing the filter, rather than supplying the water with which the filter was washed as drinking water.

Then, the filter bracket 130 can be placed in the correct position.

Additionally, a filter groove 163 may be formed on the base 116 concave downward to accommodate the lower end of the filter 120 at the tip of the first protrusion 1161.

In addition, the top of the front of the water purifier main body 100 is covered by a first cover portion 111a extending downward from the tip of the top cover 111, and the front panel 112 includes the first cover portion 111a. It covers the space between the bottom of the cover portion 111a and the tip of the base 116.

Additionally, the filter receiving groove 131 may be formed at a position facing the front panel 112. Accordingly, when the front panel 112 is separated, the filter 120 installed in the filter receiving groove 131 is exposed to the outside, and the filter 120 can be separated or replaced.

In addition, a second protrusion 1162 is formed on the base 116 and protrudes convexly upward at the position where the rear panel 115 is disposed, and the second protrusion 1162 is on the rear panel 115. ) A second groove 1151 is formed in a concave shape toward the upper side to fit into the second groove 1151.

The second protrusions 1162 may be formed at the top of both sides of the base 116. The width of the second protrusion 1162 may be gradually narrowed from the bottom to the top to form an inclined surface on the outer surface.

Additionally, like the sixth protrusion 1162, the second groove 1151 may be formed at the bottom of both sides of the front of the rear panel 115. Additionally, the width of the second groove 1151 may be gradually narrowed from the bottom to the top to form an inclined surface on the inner side.

As described above, when the second protrusion 1162 and the second groove 1151 are formed, the rear panel 115 is placed on the base 116 and the second protrusion 1162 is inserted into the second groove 1151. , the rear panel 115 can be fixed to the base 116. Then, the rear panel 115 can be placed in the correct position.

Additionally, the first and second side panels 113 and 114 may form horizontal extension portions 1133 and 1143 extending toward each other at their upper ends, respectively. The horizontal extension portions 1133 and 1143 may be formed by bending the upper ends of the first and second side panels 113 and 114, respectively.

Additionally, the coupling holes 1134 and 1144 may form an extension portion 1135 with an expanded width at the tip. The expansion portion 1135 may be formed larger than the coupling protrusion 1116.

Accordingly, the coupling protrusion 1116 can be more easily inserted into the coupling holes 1134 and 1144 through the extension portion 1135.

For example, when the top cover 111 is seated on the upper side of the horizontal extension parts 1133 and 1143, the engaging protrusion 1116 is inserted into the extension part 1135, and when the top cover 111 is pushed rearward. , the coupling protrusion 1116 can be fixed by being inserted into the coupling holes 1134 and 1144.

Additionally, the engaging protrusion 1116 may have a shape that first extends downward from the bottom of the top cover and then secondarily extends rearward.

That is, the coupling protrusion 1116 may have a shape bent backward.

In the above case, the top cover 111 is seated on the upper side of the horizontal extension parts 1133 and 1143, the engaging protrusion 1116 is inserted into the extension part 1135, and then the top cover 111 is moved backward. When pushed, the engaging protrusion 1116 is inserted into the engaging holes 1134 and 1144, and the rearwardly extending portion of the engaging protrusion 1116 contacts the bottom surface of the horizontal extensions 1133 and 1143, resulting in the horizontal extension ( As 1133 and 1143 are inserted between the top cover 111 and the rearwardly extending portion of the engaging protrusion 1116, the top cover 111 and the first and second side panels 113 and 114 can be securely fixed. .

Figure 20 is a water piping diagram of the water purifier according to the present invention.

Referring to Figure 20, the water purifier according to the present invention dispenses hot water and purified water, and the hot water and purified water are discharged through one flow path.

First, water supplied from the water supply source is guided to the filter 120 through the water supply passage 710.

And, the purified water that has passed through the filter 120 flows through the intermediate flow path 720.

One side of the intermediate passage 720 is connected to the outlet side of the filter 120, and the other side is connected to the inlet side of the hot water module 170, so that the water that has passed through the filter 120 is connected to the hot water module ( 170).

Then, purified water or hot water that has passed through the hot water module 170 is supplied to the water outlet nozzle 300 through the hot water passage 740.

The hot water passage 740 is connected to the water outlet nozzle 300 through the water outlet passage 760. Accordingly, the water that has passed through the hot water module 170 and the hot water passage 740 passes through the water outlet passage 760 and is then discharged through the water outlet nozzle 300.

At this time, when power is supplied to the hot water module 170 and purified water is heated in the hot water module 170, hot water is discharged through the water outlet nozzle 300.

Additionally, when the power to the hot water module 170 is cut off, the purified water that has passed through the hot water module 170 is not heated and is discharged through the water outlet nozzle 300 in a purified state.

That is, in the case of the present invention, hot water and purified water are discharged through one flow path.

In the case of hot water and purified water, both pass through the water supply passage 710, the filter 120, the middle passage 720, the hot water module 170, the hot water passage 740, and the water outlet passage 760, and then the water outlet nozzle 300. It is released as

The difference is whether the hot water module 170 operates. When dispensing purified water, the control unit switches the hot water module 170 to the off state so that the hot water module 170 does not operate, and the purified water that has passed through the hot water module 170 flows into the water outlet passage 760 in a purified state. It flows. On the other hand, when hot water is discharged, the control unit switches the hot water module 170 to the on state, so that the hot water module 170 operates, and the purified water passing through the hot water module 170 is heated as hot water.

The hot water module 170 includes a hot water tank. In addition, a heating passage 171 through which purified water passing through the filter 120 passes is formed in the hot water tank, and when hot water is discharged, the purified water passing through the heating passage 171 is heated to hot water. On the other hand, when purified water is discharged, the purified water that passes through the heating passage 171 maintains its state without temperature change.

Referring to FIG. 20, it includes a hot water passage 740 and a water outlet passage 760 that guide purified water or hot water that has passed through the hot water module 170 toward the water outlet nozzle 300. That is, purified water or hot water discharged from the hot water module 170 is discharged to the water outlet nozzle 300 through the hot water passage 740 and the water outlet passage 760.

The control unit controls the operation of the hot water module 170.

When dispensing purified water, the control unit turns off the heating source of the hot water module 170, and the purified water discharged from the hot water module 170 passes through the hot water passage 740 and the water discharge passage 760 to the water discharge nozzle. It is released as (300). That is, when purified water is discharged, the heating source of the hot water module 170 is turned off, so that the purified water is not heated when it passes through the heating passage 171 of the hot water module 170, and can be discharged as purified water. . In addition, purified water may be supplied to the water outlet nozzle 300 through the hot water passage 740 and the water outlet passage 760.

In addition, when hot water is discharged, the control unit turns on the heating source of the hot water module 170, and the hot water discharged from the hot water module 170 passes through the hot water passage 740 and the water outlet passage 760. It is discharged through the water outlet nozzle (300). That is, when the heating source of the hot water module 170 is turned on, purified water is heated when it passes through the heating passage 171 of the hot water module 170 and is discharged as hot water. In addition, the hot water discharged from the hot water module 170 may be supplied to the water outlet nozzle 300 through the hot water passage 740 and the water outlet passage 760.

The water purifier according to the present invention is branched from the first point (P1) of the water supply passage 710, and then has a second branch of the water supply passage 710 located at a rear end of the first point (P1) based on the direction of water flow. It may further include an auxiliary flow path 730 joining the point P2. Additionally, a flow control valve 640 may be installed in the auxiliary passage 730. The flow control valve 640 can control the flow rate of water passing through the auxiliary flow path 730.

As an example, the flow control valve 640 can adjust the flow rate of water passing through the auxiliary flow path 730 to low.

The control unit is connected to the flow rate control valve 640 and controls the flow rate control valve 640. In detail, the control unit may open or block the flow control valve 640. In addition, the control unit can adjust the degree of opening of the flow control valve 640, thereby controlling the flow rate of water passing through the auxiliary flow path 730.

Additionally, a temperature sensor that detects the temperature of water passing through the auxiliary passage 730 may be installed in the auxiliary passage 730.

The temperature sensor may be installed integrally with the flow control valve 640.

For reference, the temperature sensor may be installed in at least one of various water supply passages 710, intermediate passages 720, hot water passages 740, and outlet water passages 760. Additionally, the temperature sensor may be installed in the hot water module 170 or in the water outlet valve 670, which will be described later.

Additionally, the control unit is connected to a temperature sensor and can receive information on the temperature of water detected by the temperature sensor. Additionally, the output of the hot water module 170 or the auxiliary heater 650, which will be described later, can be controlled using the input temperature information.

Additionally, a water supply valve 630 may be installed at the first point (P1).

The water supply valve 630 can control the flow of water from the water supply passage 710 to the auxiliary passage 730.

And, the control unit can control the operation of the water supply valve 630.

As an example, the water supply valve 630 may have one inlet and two outlets. Additionally, the inlet of the water supply valve 630 may be connected to the water supply passage 710, one of the two outlets may be connected back to the water supply passage 710, and the other may be connected to the auxiliary passage 730.

The control unit can open and close the inlet of the water supply valve 630 and open and close the outlet of the water supply valve 630. The control unit can select and open one of the outlets of the water supply valve 630 and block the other one. The control unit may open all outlets of the water supply valve 630 and may block all outlets of the water supply valve 630.

Accordingly, the water flowing into the water supply valve 630 may be delivered to the water supply passage 710 or the auxiliary passage 730.

The water supply passage 710 includes a first water supply passage 711 that guides water toward the water supply valve 630 with respect to the water supply valve 630, and a filter 120 that directs water discharged from the water supply valve 630. ) may include a second water supply passage 712 that guides to the side.

As an example, water flowing into the water supply valve 630 through the first water supply passage 711 may not flow in the direction of the auxiliary passage 730, but may only flow into the second water supply passage 712.

As another example, water flowing into the water supply valve 630 through the first water supply passage 711 may flow only in the direction of the auxiliary passage 730 and may not flow into the second water supply passage 712.

As another example, the water flowing into the water supply valve 630 through the first water supply passage 711 partially flows in the direction of the auxiliary passage 730, and partially flows in the direction of the second water supply passage 712. You can.

When hot water is discharged, the controller may control the water supply valve 630 so that water flowing in through the first water supply passage 711 passes through the auxiliary passage 730. At this time, the water flowing into the water supply valve 630 is not discharged toward the second water supply passage 712, but is discharged only toward the auxiliary passage 730.

In addition, the water that has passed through the auxiliary passage 730 may join the second water supply passage 712 at the second point P2 and then be supplied to the filter 120.

Additionally, when purified water is discharged, the controller may control the water supply valve 630 so that water flowing in through the first water supply passage 711 flows only through the second water supply passage 712.

At this time, the water flowing into the water supply valve 630 is not discharged toward the auxiliary passage 730, but is discharged only toward the second water supply passage 712.

Additionally, water discharged to the second water supply passage 712 may be supplied to the filter 120.

In general, purified water passes through the filter 120 and is then supplied to the water outlet nozzle 300 through a flow path. Therefore, there is no need to adjust the flow rate of water passing through the flow path, and the larger the flow rate, the better.

However, in the case of hot water, after passing through the filter 120, it is heated to hot water and then supplied to the water outlet nozzle 300. Therefore, in order to increase the hot water temperature, it is necessary to adjust the flow rate of water flowing into the hot water module 170 to be lower than that of purified water.

In this situation, when a flow rate control valve is installed in the water supply passage 710 that supplies water to the filter 120 and the flow rate supplied to the filter 120 is adjusted to a low level, the hot water temperature increases, thereby satisfying the hot water conditions. . However, even when discharging purified water, a problem occurs in which the flow rate of purified water is reduced due to the low-adjusted flow rate.

To solve this problem, in the present invention, when purified water is discharged, the water flowing in through the first water supply passage 711 is supplied to the filter 120 through the second water supply passage 712. Since the flow rate control valve is not installed in the second water supply passage 712, a situation in which the purified water flow rate is lowered is prevented, and the purified water flow rate condition can be satisfied.

On the other hand, when hot water is discharged, the water flowing in through the first water supply passage 711 is supplied to the filter 120 through the auxiliary passage 730. A flow control valve 640 is installed in the auxiliary passage 730, and the flow rate adjusted to a low level by the flow control valve 640 flows into the filter 120, thereby lowering the flow rate supplied to the hot water module 170. , the hot water temperature can be increased and the hot water temperature conditions can be satisfied.

That is, in the case of the present invention, the path of water flowing from the water supply passage 710 to the filter 120 is divided into two, so that when purified water is discharged, water flows only through the water supply passage 710 to prevent the flow rate from decreasing, and when hot water is discharged, the water flow path is divided into two. In this case, water from the water supply passage 710 can be flowed into the auxiliary passage 730 to lower the flow rate, thereby satisfying the temperature conditions of hot water.

Meanwhile, as described above, purified water discharged from the filter 120 flows toward the hot water module 170 through the intermediate passage 720.

Then, the water flowing into the hot water module 170 is heated and discharged as hot water, or is not heated and discharged as purified water and flows through the hot water passage 740.

The hot water or purified water flowing through the hot water passage 740 flows through the water outlet passage 760 and is then supplied to the outside of the water purifier through the water discharge nozzle 300.

One side of the water outlet passage 760 is connected to the hot water passage 740 and the other side is connected to the water outlet nozzle 300.

Additionally, a water outlet valve 670 that regulates the flow of water flowing toward the water outlet nozzle 300 may be installed in the water outlet passage 760.

The control unit may control the operation of the water outlet valve 670.

In detail, the control unit may control the water outlet valve 670 to be opened when purified water, hot water, or cold water is dispensed, and may control the water outlet valve 670 to be blocked in a standby state in which water is not dispensed.

Meanwhile, after hot water is discharged, the hot water module 170 is in a heated state, and the hot water passage 740, the hot water module 170, and the water discharge passage 760 are also filled with hot water.

In this situation, when a user dispenses purified water, a problem occurs in which hot water in the hot water passage 740 or the hot water module 170 is dispensed through the water outlet nozzle 300 before the purified water is dispensed.

Therefore, after hot water is discharged and before purified water is discharged, it is necessary to drain the hot water (remaining water) remaining in the hot water passage 740, the hot water module 170, and the water discharge passage 760.

For this purpose, the water purifier of the present invention is provided with a drain passage 770.

Additionally, the water outlet valve 670 is provided as a three-way valve, and a drain flow path 770 may be connected to the water outlet valve 670.

In addition, the water flowing into the water outlet valve 670 may flow toward the water outlet nozzle 300 and may flow into the drain passage 770.

The water outlet valve 670 may have one inlet and two outlets. And, the inlet of the water outlet valve 670 is connected to the water outlet passage 760 extending toward the hot water passage 740. Also, one of the two outlets is connected to the water outlet passage 760 extending toward the water outlet nozzle 300, and the other is connected to the drain passage 770.

The control unit can open and close the inlet of the water outlet valve 670 and open and close the outlet of the water outlet valve 670. The control unit can select and open one of the outlets of the water outlet valve 670 and block the other one. The control unit may open all outlets of the water outlet valve 670 and may block all outlets of the water outlet valve 670.

Accordingly, the water flowing into the water discharge valve 670 may be discharged into the water discharge passage 760 extending toward the water discharge nozzle 300 and discharged to the water discharge nozzle 300, or may be discharged into the drain passage 770. .

For example, when hot water is discharged, the water outlet valve 670 may be opened to discharge water into the water outlet passage 760 extending toward the water outlet nozzle 300.

As another example, when the hot water discharge is terminated, the outlet connected to the drain passage 770 of the water discharge valve 670 is opened to drain the remaining water in the hot water passage 740, the water discharge passage 760, or the hot water module 170. It can be.

As described above, when draining proceeds after hot water is discharged, the hot water passage 740, the water discharge passage 760, or the hot water module 170 is filled with purified water or is empty.

Therefore, it is possible to prevent the problem of the temperature of the purified water rising due to high-temperature residual water when dispensing purified water after dispensing hot water.

If purified water is discharged without draining after hot water is discharged, even if the hot water module 170 is turned off, there is a high temperature in the hot water passage 740, the water discharge passage 760, or the hot water module 170. Since residual water remains, a problem occurs in which high-temperature water is discharged through the water discharge nozzle 300.

For reference, the drain may proceed until the remaining water in the hot water tank is discharged.

In the case of the present invention, when hot water dispensing ends, draining can proceed regardless of whether or not purified water is dispensed.

That is, when hot water is dispensed, the hot water module 170 operates, and the outlet of the water outlet valve 670 on the water outlet nozzle 300 is opened.

Then, when the hot water discharge is terminated, the hot water module 170 stops operating, and the outlet on the drain passage 770 side of the water discharge valve 670 is opened, so that the hot water in the hot water passage 740 or the hot water module 170 is drained. It is drained through flow path 770.

And, when the preset drain time elapses, the outlet of the drain valve 670 on the drain passage 770 is blocked.

In addition, in the case of the present invention, when hot water dispensing is completed and purified water dispensing proceeds, the elapsed time can be checked after hot water dispensing, and draining can be selectively performed according to the elapsed time.

In addition, in the case of the present invention, when hot water discharge is terminated and purified water discharge proceeds, the remaining water temperature in the hot water passage 740 or the water discharge passage 760, the hot water module 170, or the water discharge valve 670 is checked, and the checked water discharge valve 670 is checked. Draining can be performed selectively depending on the temperature.

Additionally, the water purifier according to the present invention may be equipped with a cold water discharge function.

For this purpose, a cold water passage 750, one side of which branches off from the middle passage 720 and the other side joins the outlet water passage 760, is installed in the cold water passage 750, and the cold water passage 750 It may further include a cold water module 150 that cools the passing purified water with cold water.

In addition, a cold and hot water valve 660 may be installed in the intermediate passage 720 at a branch point of the cold water passage 750.

The control unit controls the operation of the cold and hot water valve 660.

For example, when dispensing hot water or dispensing purified water, the control unit may control the cold and hot water valve 660 to be opened toward the hot water module 170.

As another example, when cold water is discharged, the control unit may control the cold and hot water valve 660 to be opened toward the cold water passage 750.

The cold and hot water valve 660 may have one inlet and two outlets. And, the inlet of the cold and hot water valve 660 is connected to the intermediate passage 720 extending toward the filter 120. Also, one of the two outlets is connected to the middle passage 720 extending toward the hot water module 170, and the other is connected to the cold water passage 750.

The control unit can open and close the inlet of the cold and hot water valve 660, and open and close the outlet of the cold and hot water valve 660. The control unit can select and open one of the outlets of the cold and hot water valve 660 and block the other one. The control unit may open all outlets of the cold and hot water valve 660 and may block all outlets of the water outlet valve 670.

Accordingly, the water flowing into the cold and hot water valve 660 may be discharged to the middle passage 720 extending toward the hot water module 170 and supplied to the hot water module 170, or may be discharged to the cold water passage 750. .

As a modified example, after hot water is discharged, it is in a heated state, and the hot water passage 740, the hot water module 170, and the water discharge passage 760 are also filled with hot water.

In this situation, when a user dispenses purified water, a problem occurs in which hot water in the hot water passage 740 or the hot water module 170 is dispensed through the water outlet nozzle 300 before the purified water is dispensed.

The control unit can control the temperature of water discharged from the water outlet nozzle 300 to a low level using cold water.

In this embodiment, if purified water is discharged within a preset reference time after hot water is discharged, the control unit opens the cold and hot water valve 660 at the outlet of the intermediate passage 720 connected to the hot water module 170, and cools the cold water. The outlet on the flow path 750 side is also controlled to be opened.

Here, the 'reference time' can be set in various ways. As an example, the 'standard time' may be set to 60 minutes.

In addition, after hot water is discharged, but before the standard time elapses, and when purified water is discharged, the control unit opens both outlets of the cold and hot water valve 660 simultaneously, and the outlet on the cold water passage 750 side is opened for the first time. , it is controlled to be blocked, and the outlet on the intermediate passage 720 side connected to the hot water module 170 is controlled to be open for a second time longer than the first time.

Here, 'first time' and 'second time' can be set in various ways. As an example, the 'first time' may be set to 3 seconds.

Additionally, the water discharged through the cold water passage 750 and the hot water passage 740 may join in the water outlet passage 760 and then be discharged through the water outlet nozzle 300.

In addition, in the case of the present invention, when hot water dispensing is finished and purified water dispensing proceeds, the elapsed time is checked after hot water dispensing, and a portion of the cold water can be selectively added to the remaining water according to the elapsed time.

In addition, in the case of the present invention, when hot water discharge is terminated and purified water discharge proceeds, the remaining water temperature in the hot water passage 740 or the water discharge passage 760, the hot water module 170, or the water discharge valve 670 is checked, and the checked water discharge valve 670 is checked. Depending on the temperature, some of the cold water can be selectively added to the remaining water.

According to this, the problem that hot or lukewarm water is initially discharged when purified water is dispensed due to residual hot water when dispensing purified water through the hot water passage can be solved.

At least one of a pressure reducing valve 610 that adjusts the water pressure of water flowing in from the water supply source or a flow sensor 620 that checks the flow rate of water passing through the water supply passage 710 will be installed in the water supply passage 710. You can.

For example, in the first water supply passage 711, a pressure reducing valve 610 and a flow sensor 620 may be installed in order based on the water flow direction.

Additionally, the control unit controls the water supply valve 630 so that water from the first water supply passage 711 flows into the auxiliary passage 730 during hot water sterilization.

Additionally, the controller may control the cold and hot water valve 660 so that the water flowing through the intermediate passage 720 after being discharged from the filter 120 flows toward the cold water passage 750 or the hot water passage 740.

As an example, the controller may control the cold and hot water valve 660 so that water flowing through the middle flow path 720 after being discharged from the filter 120 flows toward the cold water flow path 750.

As another example, the controller may control the cold and hot water valve 660 so that water flowing through the intermediate passage 720 after being discharged from the filter 120 flows sideways toward the hot water module 170 and the hot water passage 740.

As another example, the controller may control the cold and hot water valve 660 so that water flowing through the middle passage 720 after being discharged from the filter 120 flows toward the cold water passage 750 and the hot water passage 740.

At this time, the water flowing through the middle passage 720 after being discharged from the filter 120 may simultaneously flow toward the cold water passage 750 and the hot water passage 740.

In addition, the water flowing through the intermediate passage 720 after being discharged from the filter 120 sequentially flows first toward the cold water passage 750 and then flows toward the hot water passage 740, or flows first toward the hot water passage 740. After that, it can flow toward the cold water flow path (750).

Additionally, the controller may control the water outlet valve 670 so that water in the water outlet passage 760 flows toward the water outlet nozzle 300 or the drain passage 770 during hot water sterilization.

As an example, the controller may control the water outlet valve 670 so that water flowing into the water outlet valve 670 through the water outlet passage 760 flows toward the water outlet nozzle 300.

As another example, the controller may control the water outlet valve 670 so that water flowing into the water outlet valve 670 through the water outlet passage 760 flows toward the drain passage 770.

As another example, the control unit may control the water outlet valve 670 so that water flowing into the water outlet valve 670 through the water outlet passage 760 flows toward the water outlet nozzle 300 and also flows toward the drain passage 770. there is.

At this time, water flowing into the water outlet valve 670 through the water outlet passage 760 may simultaneously flow toward the water outlet nozzle 300 and the drain passage 770.

In addition, the water flowing into the water outlet valve 670 through the water outlet passage 760 sequentially flows first toward the water outlet nozzle 300 and then toward the drain passage 770, or first flows toward the drain passage 770 and then toward the drain passage 770. , may flow toward the water outlet nozzle 300.

In addition, the water purifier 10 of the present invention may further include a steam flow path 780 and a safety valve 190 for discharging steam generated when heating hot water in the hot water module 170. Accordingly, it is possible to prevent the pressure inside the hot water tank included in the hot water module 170 from being excessively increased by steam. The safety valve 190 is configured to open at a set pressure, and may have various structures within a range that allows smooth discharge of steam inside the hot water tank.

Meanwhile, the steam flow path 780 may also be connected to the drain flow path 770. Accordingly, vapor discharged from the hot water tank may also be discharged to the outside of the water purifier 10 through the drain passage 770.

According to the present invention as described above, since hot water sterilization progresses as continuous water discharge progresses, there is also an advantage that foreign substances can be removed simultaneously while sterilization of the flow path and valve progresses depending on the flow rate.

According to the present invention, part of the hot water generated during hot water sterilization and hot water washing of the entire flow path included in the water purifier is discharged through the water outlet nozzle, and the remainder is drained to the outside of the water purifier, so that a large amount of hot water is discharged through the water outlet nozzle. This has the advantage of preventing safety accidents such as burns and preventing users from having to process large amounts of hot water.

Meanwhile, referring to FIGS. 18 and 19, the filter bracket 130 may be equipped with a detection sensor 140 that detects whether the fixing protrusion 1121 is inserted into the fixing hole 136.

The detection sensor 140 may come in various embodiments.

As an example, the detection sensor 140 has a lowered first terminal portion, and when the fixing protrusion 1121 is inserted into the fixing hole 136 and the fixing protrusion 1121 pushes the first terminal portion, the first terminal portion is As the terminal unit rises, it is possible to detect that the front panel 112 is mounted by connecting to the second terminal unit.

On the other hand, when the front panel 112 of the detection sensor 140 is separated and the force pressing the first terminal disappears, the first terminal part descends, the first terminal part is separated from the second terminal part, and the front panel 112 This separate situation can be detected.

And, when the control unit detects the installation of the front panel 112 at the detection sensor 140, the control unit opens the water supply valve 630 and separates the front panel 112 from the detection sensor 140. When detected, the water supply valve 630 is blocked.

Generally, the front panel 112 is separated when the filter 120 is replaced.

Also, while the filter 120 is being separated or replaced, it is necessary to block the raw water flowing into the filter 120.

In the case of the present invention, rather than directly detecting whether the filter 120 is installed, whether the front panel 112 is installed is detected to prevent raw water from flowing into the filter 120 while the filter 120 is being replaced. By blocking the valve 630, problems such as water leakage can be prevented.

Meanwhile, when the filter 120 is replaced, cleaning of the filter 120 is required. Additionally, the water used to wash the filter 120 must be drained.

To this end, when the control unit detects the installation of the front panel 112 at the detection sensor 140, the water in the water outlet passage 760 does not flow toward the water outlet nozzle 300 and flows into the drain passage 770. The water outlet valve 670 can be controlled to drain to the outside.

That is, for filter replacement, when the front panel 112 is separated, the detection sensor 140 detects the separation of the front panel 112, and the control unit detects the separation of the front panel 112 through the detection sensor 140. recognize

Then, the water supply valve 630 is blocked to block the inflow of raw water into the filter 120.

Then, replacement of the filter 120 is performed while the inflow of raw water is blocked.

Thereafter, when the replacement of the filter 120 is completed and the front panel 112 is mounted, the detection sensor 140 detects the installation of the front panel 112, and the control unit detects the front panel 112 through the detection sensor 140. ) Recognize the installation of

Then, the water supply valve 630 is opened to allow raw water to flow into the filter 120.

Then, the filter 120 is cleaned.

At this time, the water outlet valve 670 is controlled so that the water used to clean the filter 120 is not supplied to the water outlet nozzle 300.

Under the control of the control unit, the water outlet valve 670 blocks the outlet on the water outlet nozzle 300 side and opens the outlet on the drain passage 770 side.

Afterwards, when the set time elapses or when draining of the set flow rate is completed, the drain is terminated.

Additionally, cleaning of the filter 120 may be performed for a set time or at a set flow rate. Additionally, the cleaning of the filter 120 can proceed as long as the user desires, and when the user inputs the end of filter cleaning through the control panel, etc., the cleaning of the filter may be terminated.

When cleaning of the filter 120 is completed, the control unit may block the water discharge valve 670 to terminate draining.

According to the present invention, when installing a water purifier, the position of the water purifier module can be set considering a direction that is convenient for the user to access. In general, the direction in which the user approaches the water purifier is consistent, so if the user sets the position of the water outlet module and fixes the water outlet module to the water purifier body, the user can conveniently access the water outlet module at any time.

In addition, since the water outlet module is raised and lowered while being fixed to the water purifier main body, the water outlet module can be raised and lowered stably even when force is applied in the horizontal direction.

Additionally, the horizontal position of the water outlet nozzle is fixed in one direction, and the vertical position can be changed depending on the height of the container.
