1 is a block diagram showing a water treatment apparatus and a cleaning apparatus according to the present invention.

Referring to FIG. 1, the cleaning apparatus for the water treatment apparatus is an apparatus for cleaning the internal flow path of the water treatment apparatus while circulating the cleaning water through the water treatment apparatus.

First, an example of a water treatment apparatus to which the cleaning apparatus according to the present invention is applied will be described.

The water treatment apparatus 1 includes a filter unit 10 for filtering the water introduced from a water pipe 5 or a water bottle for a replaceable dispenser. The filter unit 10 may include a sediment filter, a pre-carbon filter, a membrane filter, and a post-carbon filter.

In the sediment filter, a nonwoven fabric is applied to filter foreign matters and suspended matters contained in raw water. The above-mentioned free carbon filter is subjected to filtration of chlorine components and odors contained in raw water by applying surfactant charcoal. The membrane filter passes the porous membrane using cellulose-based fibers to filter the raw water. The post-carbon filter is relatively more excellent in adsorbing force than the surfactant carbon in the pre-carbon filter, thereby removing coloring matter and odor.

The water treatment apparatus (1) includes a purified water storage unit (20) in which the purified water filtered in the filter unit (10) is stored. The purified water storage unit 20 includes a purified water tank 21 for storing purified water in the filter unit 10, a cold water tank 23 for entering purified water discharged from the purified water tank 21, 25). Also, the purified water storage unit 20 may include only the cold water tank 23 and the hot water tank 25.

A cooler (not shown) for cooling the purified water is installed in the cold water tank 23, and a heater (not shown) for heating the purified water may be installed in the hot water tank 25.

The water level adjusting unit 22 may be installed on the inflow side of the purified water storing unit 20 to measure the water level as the purified water passes. At this time, the water level adjusting unit 22 may be disposed at the purified water inlet side of the purified water tank 21 so that the purified water discharged from the filter unit 10 can flow into the purified water tank 21. The water level controller 22 senses the level of the purified water tank 21 by passing the purified water and blocks the flow of purified water when the purified water tank 21 is full.

The purified water storage portion 20 is connected to the drain portion 30 by a purified water pipe. The drainage unit 30 includes a cold / purified water take-out cock 31 connected to the purified water tank 21 and the cold water tank 23, a hot water take-out cock 32 connected to the hot water tank 25, And drain pipes 33 and 34 for draining the water in the tank 23 and the hot water tank 25 to the outside, respectively.

The connection terminal 51 of the control unit 50 is detachably coupled to a connection terminal (not shown) of a wiring (not shown) for supplying power to the electronic valve.

Next, the cleaning apparatus for the water treatment apparatus will be described.

Fig. 2 is a block diagram showing the construction of the cleaning device, and Fig. 3 is a perspective view showing the cleaning device.

2 and 3, the cleaning apparatus 100 includes a cleaning apparatus 100 including circulation members 111-114 and 117, a circulation module 120, a cable 185, and a power supply unit 183 ).

The circulation members (111-114, 117) are connected to the flow path of the water treatment apparatus so as to circulate the washing water through the flow path of the water treatment apparatus (1). These circulating members 111-114 and 117 form an infinite loop together with the flow path of the water treatment apparatus.

The circulation members 111-114 and 117 include at least one connection pipe 111-114 connected to the drainage unit 30 of the water treatment apparatus 1 and a circulation pipe connected to the discharge side of the filter unit 10 of the water treatment apparatus 1, (117).

It is preferable that the connection pipes 111-114 are formed in such a number as to be sufficiently connected to the drainage structure such as the extraction corks 31 and 32 and the drain pipes 33 and 34 of the water treatment apparatus 1. [ Accordingly, in the case of a water treatment apparatus in which the number of drainage structures is small, some of the connection pipes 111-114 are connected to the volleyball structure, but the remaining connection pipes are not connected to the drainage structure.

The connection pipes 111-114 may be detachably connected to the take-out corks 31, 32 and / or the drain pipes 33, 34 constituting the drainage part 30. [ At one end of each of the connection pipes 111-114 is provided a fitting device or connectors 111a-114a or the like (hereinafter, referred to as " Connector ") may be combined. In addition, connectors 111a-114a may be coupled to the other ends of the connection pipes 111-114 so as to be detachably connected to the connection ports 131-134 of the circulation module 120.

The connectors 111a to 114a are connected to the take-out cocks 31 and 32 and the drain pipes 33 and 34 and are easily pulled out or pushed to separate them from the take-out cocks 31 and 32 and the drain pipes 33 and 34 Or the like. The structures of the connectors 111a-114a may be formed in various forms.

The circulation pipe (117) may be connected to the discharge side of the filter unit (10). For example, the circulation pipe 117 may be detachably coupled to the purified water tank 21 from the discharge side purified water pipe 22 or the purified water storage unit 20 of the filter unit 10. At this time, a connector 117a having the same shape as the connectors 111a-114a of the connection pipe 111-114 may be installed at both ends of the circulation pipe 117. [

The connector 117a of the circulation pipe 117 may be connected to the discharge side purified water pipe 22 of the filter unit 10 after the filter unit 10 is separated from the water treatment apparatus 1. [ Here, the discharge side purified water pipe 22 of the filter unit refers to a purified water pipe connecting the filter unit 10 and the purified water tank 21.

The connector 117a of the circulation pipe 117 may be connected to the water level adjusting unit 22 after separating the water level adjusting unit 22 of the purified water storing unit 20 from the purified water pipe.

The connection pipe 111-114 or the circulation pipe 117 may be provided with a mesh network 115 for filtering the washing water. The mesh network 115 has meshes such that the water pressure of the washing water is not applied to the connection pipes 111-114 and the circulation pipe 117. In FIG. 2, the mesh network 115 is installed in the connectors 111a-114a of the connection pipes 111-114.

At this time, the mesh network 115 may be detachably coupled to the connectors 111a-114a at the other end of the connection pipes 111-114. Therefore, it is easy to clean the mesh net 115 or to replace the mesh net 115 with a new one before or after the connection pipes 111-114 are installed in the water treatment apparatus 1. [

The connection pipe 111-114 is connected to the extraction cocks 31 and 32 and the drain pipes 33 and 34 disposed in the water treatment device 1 after the circulation module 120 is placed on the floor surface, As shown in Fig. The circulation pipe 117 is connected to the discharge side purified water pipe 22 or the purified water tank 21 of the filter unit 10 disposed on the water treatment device 1 after placing the circulation module 120 on the bottom surface Or the like. Therefore, the circulation pipe 117 may be relatively longer than the connection pipes 111-114.

The circulation module 120 may be provided with a detergent input unit 121 and a neutralizer input unit 122 so that a detergent and a counteragent may be input. The cleanser input portion 121 and the neutralizer input portion 122 may be connected to the washing water discharge side or the inflow side of the circulation pump 173. Therefore, the cleaning agent and the neutralizing agent can be mixed with the purified water in a short period of time by injecting the cleaning agent and the neutralizing agent into the portion where the washing water flows most actively in the circulation module 120.

It is needless to say that a user or an administrator can directly apply a cleaning agent and a neutralizing agent to the flow path of the purified water tank 21 and the circulation module 120 without installing the detergent input unit 121 and the neutralizer input unit 122 in the circulation module 120 can do.

As the detergent, various chemicals may be used as long as the inner surface of the water treatment apparatus can be cleaned and sterilized. In addition, the neutralizing agent should be appropriately applied to the cleaning agent depending on the components thereof.

As an example of the cleaning agent, Korean Patent Laid-Open No. 10-2006-0129670 can be applied. The cleaning method includes a first cleaning step of cleaning with a first cleaning solution containing chlorine dioxide and a second cleaning step of cleaning with a second cleaning solution containing ammonium ions and hydroxide ions. According to the present invention, various detergents other than the above-mentioned detergents can be applied.

Two or more connection ports 131-134 to which the connection pipes 111-114 are connected and a circulation port 137 to which the circulation pipe 117 is connected may be formed in the circulation module 120 have. At this time, the connection ports 131-134 are detachably connected to the connectors 111a-114a of the connection pipes 111-114, and the circulation port 137 is connected to the connectors 117a and 117b of the circulation pipe 117, Detachably connected.

The connection ports 131-134 may be formed on the upper surface of the case of the circulation module 120. [ Therefore, the connectors 111a-114a of the connection pipes 111-114 can be easily coupled from above the connection ports 131-134 while the circulation module 120 is placed on the floor or the like. In addition, it is possible to visually check whether the plurality of connection pipes 111-114 are normally connected to the connection ports 131-134.

The circulation port 137 may be formed on the case side of the circulation module 120. Therefore, the connector 117a of the circulation pipe 117 may be coupled to the circulation port 137 of the circulation module 120, and then the circulation module 120 may be placed on the floor or the like.

The circulation module 120 is connected to the connection ports 131-134 and the connection ports 141 and connects the connection ports 141 to the circulation port 137 An integrated flow path portion 142 may be formed.

The circulation module 120 sequentially opens some of the flow paths communicating with the connection pipes 111-114 so that the flow rate of the fluid flowing through the flow paths of the filter units 10 of the water treatment device 1 Closing means 160 for circulating the washing water. The opening / closing means 160 will be described in detail below.

The circulation module 120 is provided with an operation unit (not shown) for setting the number of opening and closing of the connection ports 131-134 according to the number of the extraction corks 31, 32 and the drain pipes 33, 34 of the water treatment apparatus 1 150) may be further included. At this time, information on the number of the extraction corks 31, 32 and the number of the drain pipes 33, 34 can be visualized through the display unit 153 on the operation unit 150.

Accordingly, when the user or the manager inputs the number of the extraction cocks 31 and 32 and the number of the drain pipes 33 and 34 through the operation unit 150, the control unit 180 of the circulation module 120 controls the opening / (1) can be sequentially cleaned by a part of the channels while controlling one of the take-out corks (31, 32) and the drain pipes (33, 34) have.

It is possible to sequentially clean the cold water tank 23, the drain pipe 33 of the cold water tank 23, the hot water tank 25, and the drain pipe 34 of the hot water tank 25, for example. The hot water tank 25 and the drain pipe 34 may be cleaned simultaneously after the cold water tank 23 and the drain pipe 33 are simultaneously cleaned.

Although not shown, a coupling detection sensor (not shown) may be installed on the connection ports 131-134 of the circulation module 120 to detect whether the coupling pipes 111-114 are engaged or not. have. In this case, when the connection pipe 111-114 is coupled to the connection port 131-134, the control unit 180 of the circulation module 120 determines which connection port 131- 134). The control unit 180 of the circulation module 120 controls the opening and closing means 160 so that some connection ports 131-134 of the connection ports 131-134 to which the connection pipe 111-114 is coupled, So that a part of the internal flow paths of the water treatment device 1 can be sequentially opened by a part of the flow paths.

The operation portion 150 of the circulation module 120 is provided with button portions 151a-151f for the number of the extraction corks 31,32 and the drain pipes 33,34, circulation cleaning, cleaning water neutralization, Can be formed. The buttons 151a-151f may be mechanically or touch-pad-operated.

Also, the display unit 153 and the buzzer 155 may be installed on the operation unit 150 to display an error message of the wash water or to notify the user of the error message. The display unit 153 may be an LED or a liquid crystal display panel.

The circulation module 120 includes a washing water discharge pipe 148 connected to the circulation members 111-114 and 117 and a connection part between the washing water discharge pipe 148 and the circulation members 111-114 and 117, And a circulation pump 137 connected to the circulation member for circulating the wash water to the channel of the water treatment apparatus 1 or the wash water drain pipe 148.

At this time, the wash water drain pipe 148 is connected to the connection part between the connection pipe 111-114 and the circulation pipe 117. [ The flow path switching unit 171 may be coupled to the connecting portion of the connection pipe 111-114, the circulation pipe 117, and the discharge pipe 148. [ The circulation pump 137 may be connected to the connection pipe 111-114 or the circulation pipe 117.

The wash water drain pipe 148 may be detachably connected to the drain port 144 of the circulation module 120. At this time, the wash water drain pipe 148 discharges the wash water drained from the circulation module 120 to the sink or the drain.

The flow path switching unit 171 provides a three way valve for selectively flowing the washing water flowing into the connection pipes 111-114 to either the circulation pipe 117 or the drain pipe 148.

The circulation pump 173 may have a structure in which an impeller (not shown) and a pumping motor (not shown) are installed therein.

The circulation module 120 may further include a wash water sensing unit 175.

The washing water detecting unit 175 may be a hydraulic pressure sensor or a flow rate sensor.

The wash water sensing unit 175 is preferably disposed on the wash water discharge side of the circulation pump 173. The reason for this is as follows.

The circulation pump 173 may not operate normally or the opening and closing means 160 may not completely open the flow path of the connection ports 131-134 or the take-out cock may not open normally. In this case, sufficient water pressure may not be formed on the washing water discharge side of the circulation pump 173. Therefore, by installing the washing water sensing unit 175 on the washing water discharge side, it is possible to accurately determine whether the opening and closing means 160 and the circulation pump 173 are operating normally.

4 is an exploded view showing a connection pipe and a connection port constituting the cleaning device.

Referring to FIG. 4, a check valve 136 may be installed at each of the connection ports 131-134 of the circulation module 120. The check valve 136 opens the flow path of the connection port 131-134 when the connection pipe 111-114 is connected, but opens the connection port 131-134 when the connection pipe 111-114 is not connected. As shown in Fig.

At this time, each check valve 136 includes an opening / closing member 136a disposed inside the connection port 131-134, a spring 136b elastically supporting the opening / closing member, And a packing 136c coupled to the upper side to close the connection ports 131-134 in a state where the opening and closing member is raised.

When the connecting pipe 113 is not coupled to a part of the connection port 133 of the connection port 131-134, the opening / closing member 136a of the check valve 136 is not pressed, The flow path of the connection port 133 is closed.

At this time, the check valve 136 can block the inflow of external air through the connection port 133 by the action of the spring 136b and the packing 136c. Therefore, it is possible to prevent air from being sucked into the opening / closing means 160 through the connection port 133 to which the connection pipe 113 is not coupled. Since the disk 163 of the opening and closing means 160 closes the connection port 133 to which the connection tube 113 is not coupled, the connection port 133, to which the connection tube 113 is not coupled, So that the inflow of the air is blocked.

Therefore, by minimizing the formation of bubbles in the washing water in the opening / closing means 160, the circulating pump 173 can pump the washing water normally and maintain the water pressure of the washing water constant. Therefore, the pumping noise of the washing water generated by the circulation pump 173 can be reduced.

Also, the cleaning performance can be improved.

In addition, it is possible to minimize the generation of bubbles in the circulating pump 173 or the circulating pipe 117, thereby reducing the flow noise of the circulating pipe 117.

Although not shown, the opening and closing means 160 may include a plurality of solenoid valves individually installed in the connection ports 131-134. At this time, each solenoid valve opens and closes a flow path of the corresponding connection port 131-134 as power is applied by the circulation module 120.

Since the solenoid-type opening and closing means is applied with a plurality of solenoid valves, it is possible to precisely control opening and closing of the connecting ports 131-134. In addition, air can be prevented from flowing into the opening / closing means 160 through the connection ports 131-134.

6 is a configuration diagram showing a structure in which the control unit of the cleaning apparatus and the control unit of the water treatment apparatus are connected to the power supply cable.

Referring to FIG. 6, a power supply terminal 181 may be formed in the circulation module 120 so as to be connected to the electromagnetic valve of the water treatment apparatus 1 by a power supply cable 185. The power supply terminal 181 is electrically connected to the power supply unit 183 and the power supply unit 183 is electrically connected to the control unit 180.

The power supply terminal 181 is connected to one terminal of the power supply cable 185 and the connection terminal 51 of the water treatment apparatus 1 is connected to the other terminal of the power supply cable 185. The cleaning device 100 supplies power to the extraction cocks 31 and 32 of the water treatment device 1 by the power supply cable 185 so that the extraction cocks 31 and 32 of the water treatment device 1, 32 are opened. Therefore, when the water treatment apparatus is washed, the take-out coke is opened.

The cleaning device 100 can be commonly used for a type in which the extraction corks 31 and 32 of the water treatment device 1 are manually opened and closed and a type in which the extraction corks 31 and 32 are opened and closed electromagnetically.

The process of installing the cleaning apparatus for water treatment apparatus according to the present invention in the water treatment apparatus will be described.

Referring to FIG. 2, when the water treatment apparatus 1 needs to be cleaned, the power supply plug (not shown) of the water treatment apparatus 1 is disconnected to cut off the power supply.

When hot water is filled in the hot water tank 25 of the water treatment apparatus 1, the hot water take-out cock 32 is opened to drain the hot water completely. The reason for this is to prevent the operator from burning with hot water when connecting the cleaning apparatus 100 to the water treatment apparatus 1. [

3 and 4, one end of the connecting pipe 111-114 is connected to the cold / purified water take-out cock 31, the hot water take-out cock 32 and the drain pipes 33 and 34 of the water treatment apparatus 1, And the other ends of the coupling tubes 111-114 are coupled to the coupling ports 131-134 of the circulation module 120, respectively.

At this time, as the mesh network 115 of the connection pipe 111-114 presses the check valve 136, the flow path of the connection port 131-134 is opened (see FIG. 4). In addition, the connection ports 131-134, to which the connection pipe 111-114 is not coupled, are closed by the check valve 136 to block external air from flowing into the internal flow path of the cleaning device 100. [

One side of the circulation pipe 117 is connected to the discharge side purified water pipe 22 of the filter unit 10 or the water level control unit 22 of the purified water tank 21. The other side of the circulation pipe 117 is coupled to the circulation port 137 of the circulation module 120.

Both terminals of the power supply cable 185 are connected to the connection terminal 51 of the water treatment apparatus 1 and the power supply terminal 181 of the circulation module 120 (see FIG. 6).

If the cleanser input unit 121 and the neutralizer input unit 122 are not installed in the washing apparatus 100, the purified water tank 21 of the water treatment apparatus 1 is opened, can do.

In addition, when the cleanser input unit 121 is installed in the cleansing device 100, the cleanser may be automatically inserted through the cleanser input unit 121.

The power cord 147 of the circulation module 120 is connected to an external power source and the switch 148 of the circulation module 120 is operated to input power to the cleaning device 100.

The cleaning method and operation of the water treatment apparatus according to the present invention will be described below.

7 is a flowchart showing a cleaning method of the cleaning apparatus according to the present invention.

Referring to FIG. 7, the operation unit 150 of the circulation module 120 is operated to set the number of connection between the extraction cocks 31 and 32 and the drain pipes 33 and 34. Thus, the washing mode is set (S11).

When the circulation cleaning button 151b or the collective cleaning button 151f is selected through the operation unit 150 of the cleaning apparatus 100, the controller 180 of the cleaning apparatus 100 controls the power supply unit 183 And supplies power to the connection terminal 51 of the water treatment apparatus 1. [ As the power is supplied to the connection terminal 51, the take-out corks 31 and 32 are opened (S12). At this time, all the take-out corks 31 and 32 of the water treatment apparatus can be simultaneously opened.

The control unit 180 of the washing apparatus 100 operates the opening and closing means 160 of the circulation module 120, the circulation pump 173, the washing water sensing unit 175 and the flow path switching unit 171 .

At this time, when washing water is simultaneously supplied to all the flow paths of the water treatment apparatus 1, the water pressure deviation of the washing water may be partially generated according to the flow path structure of the water treatment apparatus 1. That is, the water pressure of the washing water is high in some of the flow paths of the water treatment apparatus 1, while the water pressure of the washing water is extremely low in the other flow paths. In this way, when the washing water is simultaneously supplied to all the flow paths of the water treatment apparatus, the water pressure of the washing water is remarkably low, so that a dead zone is not generated.

In order to prevent the occurrence of the washing yarn area as described above, the washing water is flowed as follows.

The control unit 180 of the washing apparatus 100 controls the opening and closing means 160 to sequentially open one or more of the take-out corks 31 and 32 and the drain pipes 33 and 34, The washing water can be caused to flow sequentially through the inside of the washing tub 1 by a part of the flow path.

The case where the cold water tank 23, the drain pipe 33 of the cold water tank 23, the hot water tank 25 and the drain pipe 34 of the hot water tank 25 are cleaned in that order will be described below.

The control unit 180 of the cleaning apparatus 100 opens the connection pipe 111 and the circulation pipe 117 (S13). That is, the opening / closing means 160 is operated to open the flow path of the connection port 131 connected to the cold / water take-out cock 31 and close the flow path of the remaining connection ports 132-134.

As the circulation pump 173 is operated, the washing water of the purified water tank 21 and the cold water tank 23 is discharged through the cold / purified water take-out cock 31 (S14).

In addition, the control unit 180 of the cleaning apparatus 100 switches the flow path switching unit 171 to the circulation mode (S15). At this time, the control unit 180 of the washing apparatus 100 causes the circulation pipe 117 to be opened by the flow path switching unit 171 and to close the washing water discharge pipe 148 side.

The washing water of the cold / purified water take-out cock 31 flows into the water level adjusting unit 22 along the circulation pump 173, the washing water sensing unit 175, the flow path switching unit 171 and the circulation pipe 117. The washing water flowing into the water level adjusting unit 22 flows into the purified water tank 21 and the cold water tank 23.

During this process, the wash water sensing unit 175 measures the water pressure or flow rate of the wash water and transfers it to the control unit 180 of the cleaning device 100.

The control unit 180 of the washing apparatus 100 may stop the circulation pump 173 when the water pressure or the flow rate of the washing water does not reach a preset value, / &Quot; and / or " buzzer " Otherwise, the circulation pump 173 is continuously operated.

The purified water tank 21, the cold water tank 23, some purified water pipes, the cold / purified water take-out cock 31 and the water level regulating portion 22 are cleaned while the circulation of the wash water is continued for a predetermined time.

Next, the controller 180 of the cleaning apparatus 100 operates the opening and closing means 160 to open the connection port 132 connected to the hot water take-out cock 32, and the remaining connection ports 131, 133, . At this time, the circulation pump 173 can be temporarily stopped or continuously operated while the opening and closing means 160 is operated.

The washing water in the hot water tank 25 is discharged through the hot water take-out cock 32. The washing water of the hot water coat flows into the water level adjusting unit 22 along the circulation pump 173, the washing water sensing unit 175, the flow path switching unit 171 and the circulation pipe 117. The washing water flowing into the water level adjusting unit 22 flows into the purified water tank 21 and the hot water tank 25.

As the water is circulated in the purified water tank 21, the hot water tank 25 and the flow path, the hot water tank 25 and the flow path are cleaned.

The control unit 180 of the cleaning apparatus 100 operates the opening and closing means 160 to open the connection port 133 connected to the drain pipe 33 of the cold water tank 23, 131, 132, 134). Accordingly, the purified water tank 21, the cold water tank 23, and the drain pipe 33 of the cold water tank 23 are cleaned.

The control unit 180 of the cleaning apparatus 100 operates the opening and closing means 160 to open the connection port 134 to which the drain pipe 34 of the hot water tank 25 is connected, -133). Accordingly, the purified water tank 21, the hot water tank 25, and the drain pipe 34 of the hot water tank 25 are cleaned.

During the washing process of the hot water tank 25 and the drain pipes 33 and 34, the washing water sensing unit 175 measures the water pressure or the flow rate of the washing water and transmits it to the controller 180 of the washing apparatus 100 . The control unit 180 may stop the circulation pump 173 and notify an error message or an alarm if the water pressure or the flow rate of the washing water has not reached the predetermined value.

As described above, the cleaning apparatus 100 includes the purified water tank 21, the cold water tank 23, the hot water tank 25, the drain pipe 33 of the cold water tank 23, and the drain pipe 34 so that the water pressure deviation of the washing water hardly occurs on the flow path through which the washing water flows. Therefore, the flow path of the water treatment apparatus 1 can be cleaned cleanly.

The cleaning device 100 may include not only tanks 21, 23, and 25 to which human hands or cleaning tools can reach, but also a purified water pipe and a cold / The drain pipes 33 and 34, and the water level regulating part 22, as shown in FIG.

Next, if it is determined that the circulation cleaning time has been reached in the control unit 180 of the cleaning apparatus 100 (S16), the circulation pump 173 may be stopped (S17). In addition, the control unit 150 may notify the user of a message or / and alarm about the completion of the cleaning through the display unit 153 and / or the buzzer 155.

The control unit 180 of the cleaning apparatus 100 determines whether the neutralizing agent has been charged into the water tank 21 or the cleaning apparatus 100 at step S18.

If it is determined that the neutralizing agent has been charged, the circulation pump 173 is operated (S19). At this time, the flow path switching unit 171 opens the circulation pipe 117 and closes the wash water discharge pipe 148 so that the wash water of the circulation pump 173 flows into the circulation pipe 117.

At this time, when the washing water is neutralized, the washing water can be circulated sequentially through a part of the plurality of flow paths on the discharge side of the filter unit, as in the washing mode. That is, the washing water containing the neutralizing agent can be sequentially circulated in the cold water tank 23, the hot water tank 25, the drain pipe 33 of the cold water tank 23, and the drain pipe 34 of the hot water tank 25 .

Therefore, when neutralizing the washing water, the water pressure difference generated in the flow path of the water treatment apparatus is minimized, so that the washing agent adhered on the tank or the flow path of the water treatment apparatus can be uniformly neutralized as a whole. In addition, even in the neutralization mode of the wash water, the section where the wash water stagnates in a part of the water treatment apparatus can be originally eliminated.

Also, during the neutralization process of the washing water, the washing water sensing unit 175 measures the water pressure or the flow rate of the washing water and transfers it to the controller 180 of the washing apparatus 100. The control unit 180 may stop the circulation pump 173 and notify an error message and / or an alarm when the water pressure or the flow rate of the washing water has not reached the predetermined value.

If it is determined that the predetermined neutralization time has been reached (S20), the control unit 180 of the cleaning apparatus 100 switches the flow path switching unit 171 to the drain mode (S21). At this time, the flow path switching unit 171 closes the circulation pipe 117 and maintains the state in which the washing water discharge pipe 148 is opened.

Accordingly, the washing water of the water treatment apparatus 1 is sufficiently neutralized by the neutralizing agent, and then discharged to the outside through the washing water drain pipe 148. At this time, the circulation pump 173 can be continuously operated.

In addition, the control unit 180 of the cleaning apparatus 100 may inform the user of the completion of the neutralization mode through a display or / and an alarm.

Next, the control unit 180 of the cleaning apparatus 100 determines whether the drainage mode is completed (S22). The control unit 180 of the washing apparatus 100 calculates the water pressure and the flow rate sensed by the wash water sensing unit 175 or accumulates the time when the flow path switching unit 171 is switched to the drain mode, Can be determined.

If it is determined that the drainage mode is completed, the control unit 180 of the washing apparatus 100 informs the completion of drainage mode through a display or / and an alarm. Further, the circulation pump 173 is stopped (S23).

Then, fresh water is supplied to the water treatment apparatus 1 (S24). That is, the user or the control unit 180 of the cleaning apparatus 100 may allow water to flow into the purified water tank 21 through a water pipe or the like.

At this time, the controller 180 of the washing apparatus 100 increases the fresh water to the purified water tank 21. When the purified water tank 21 is full, water supply to the water treatment apparatus 1 is stopped.

By stopping drainage for a predetermined time after the water tank 21 is full, the neutralizing agent and the cleaning agent remaining in the water tank 21 can be sufficiently cleaned.

Then, the water in the purified water tank 21 is drained after a predetermined time has elapsed after the water tank 21 is full. In the cleaning apparatus 100, it is determined whether the water is completely drained from the purified water tank 21, and the completion of the cleaning mode is determined.

If it is determined that the cleaning mode is completed (S25), the control unit of the cleaning apparatus 100 informs the user that the cleaning mode is completed through the display of the operation unit 150 and / or an alarm.

In addition, the controller 180 of the washing apparatus controls the power supply unit 183 to cut off power to the water treatment apparatus. At this time, all the water intake cocks 31 and 32 of the water treatment apparatus are closed (S26).

As described above, the cleaning device cleans the water treatment device by a portion of the flow channel, neutralizes the wash water, and cleans the remaining detergent or neutralizing agent. Thus, the user can drink a clean purified water after cleaning the cleaning device.

Industrial Applicability The present invention can be cleaned up to a portion of the water treatment apparatus not touching a hand or a cleaning tool, and thus has remarkable industrial applicability.
