[0037] Referring to the accompanying drawings, the foregoing objects, features, and advantages will be described in detail, whereby those of ordinary skill in the art to which the present invention pertains can easily implement the technical idea of the present invention. In the process of describing the present invention, when it is determined that a detailed description of well-known techniques related to the present invention will obscure the gist of the present invention, the detailed description thereof will be omitted. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote the same or similar components.

[0038] Hereinafter, an integrated water purification supply system capable of supplying a sufficient amount of purified water to a plurality of household appliances using water and a control method thereof will be disclosed.

[0039] Figure 1 It is a conceptual diagram of an integrated water purification supply system according to an embodiment. Figure 2 It is a structural diagram of an integrated water purification supply system according to an embodiment.

[0040] An integrated water purification supply system according to an embodiment includes an integrated water purifier 100 and a plurality of household appliances 200.

[0041] The integrated water purifier 100 of the integrated water purification supply system purifies water and supplies it to the plurality of household appliances 200. The integrated water purifier 100 is connected to the plurality of household appliances 200 and supplies purified water either collectively or separately.

[0042] The integrated water purification supply system aims to efficiently supply clean and sufficient amounts of purified water to the household appliances 200 using water through a single integrated water purifier 100.

[0043] The integrated water purifier 10 communicates with the plurality of household appliances 200 through a communication module to check whether water is being used, and controls the driving of a plurality of supply valves corresponding to each household appliance 200 to supply purified water at the water output rate set for each household appliance 200.

[0044] The integrated water purifier 100 can supply drinking water, cooking and rinsing water, and cleaning water to the corresponding household appliances 200.

[0045] The inflowing raw water passes through the pressure reducing valve 11, flow sensor 12, feed valve 13, filters 16, 17 in the modular integrated water purifier 100 and flows into each household appliance 200 that requires water.

[0046] If a raw water supply input is requested for the water purifier, faucet, cooking water, refrigerator, dishwasher, coffee maker, beer brewing machine, etc. according to the user's request, the purified clean water will be discharged through the respective supply valves 18, 20, 22, 23, 24 and provided to the household appliance 200 selected by the consumer.

[0047] In addition, in order to drive the product normally in a low water pressure area, a pump 140 can be provided.

[0048] As Figure 2 shown, the integrated water purifier 100 can also include a flow regulating valve 14 and a heater 15, and the feed valve 13 can be moved to a sterilization valve that changes the flow path. The feed valve 13 can change the flow path and supply the raw water through the flow regulating valve 14 and the heater 15. The regulating valve 14 and the heater 15 are used to sterilize the flow path in the integrated water purifier 100.

[0049] The integrated water purifier 100 further includes an electrolyzed water module 19 and a sterilized water outlet valve 21. The electrolyzed water module 19 can be supplied to the household appliance 240 that requires cooking water or cleaning water. The sterilized water outlet valve 21 is used to discharge the water that has been used to sterilize the flow path in the integrated water purifier 100.

[0050] On the other hand, structurally, the integrated water purifier 100 can include a mechanical chamber, a cooling section, a housing, a bottom plate, and a water outlet section. The integrated water purifier 100 can have the functions of filtering the tap water (city water) flowing in from the water pipe, cooling the water to make cold water, and heating the water to make warm water.

[0051] The mechanical chamber can be provided at the lower part of the integrated water purifier 100 and can be configured with various components that make the integrated water purifier 100 operate. The cooler can be configured above the mechanical chamber and cool the water. An evaporator for cooling the water can be configured in the cooler. The water purifier can cool the water through a refrigeration cycle using a refrigerant that undergoes a phase change.

[0052] A refrigeration cycle may include a compressor, a condenser, an expander, and an evaporator, and may be provided with piping that connects the respective devices and circulates a refrigerant through these devices. In the refrigeration cycle, the refrigerant that acts as a working fluid may be formed of various substances such as, for example, Hydro Chloro Fluoro Carbon (HCFC) compounds, Hydro Fluoro Carbon (HFC) compounds, Hydro Fluoro Olefin (HFO) compounds, etc.

[0053] The gaseous refrigerant discharged from the evaporator may flow into the compressor, and the refrigerant may be compressed in the compressor and discharged from the compressor as a high-temperature and high-pressure gas and flow into the condenser.

[0054] The refrigerant may be deprived of heat by the surroundings while passing through the condenser and condense from a gas state to a liquid state, and may be discharged from the condenser and flow into the expander.

[0055] The refrigerant may adiabatically expand while passing through the expander, and a part of it may vaporize and become a saturated state of a gas-liquid mixture. The refrigerant may lose the heat of vaporization through adiabatic expansion, whereby the temperature may drop sharply. The saturated-state refrigerant discharged from the expander may flow into the evaporator.

[0056] The refrigerant may absorb the heat of the surroundings and vaporize while passing through the evaporator, and almost most of it may be discharged from the evaporator in a vaporized state and flow into the compressor.

[0057] While repeating the aforementioned cycle, the refrigerant may discharge heat to the surroundings from the condenser and may absorb heat from the surroundings in the evaporator. Thus, in the refrigeration cycle, the heat of water may be taken from around the evaporator and the water may be cooled.

[0058] That is, in the cooler of the water purifier, heat exchange occurs between the evaporator and the cooling coil through which water flows. The refrigerant flowing in the evaporator may absorb heat and change from a liquid phase to a gas phase, and the water flowing in the cooling coil may be deprived of heat to be cooled.

[0059] In addition, the integrated water purifier 100 may include a filter for filtering tap water flowing in from a water pipe. The filter may be formed of, for example, a carbon block filter, an Ultrafiltration (UF) filter, etc., and a plurality of filters may also be provided in the water purifier.

[0060] The water that has passed through the filter may be directly discharged from the water outlet, or may be discharged from the water outlet after being cooled by the cooler, or may be discharged from the water outlet after being heated by the heating unit.

[0061] Figure 3 is a block diagram of an integrated water purification supply system according to an embodiment. Figure 4 is a flowchart showing drive control of an integrated water purification supply system according to an embodiment.

[0062] Referring to Figure 3 and Figure 4 an integrated water purification supply system according to an embodiment includes a communication module 110, an integrated water purifier 100, a plurality of home appliances 210, 220, 230, 240, a plurality of supply valves 18, 20, 22, 23, 24, a pump 140, a memory 130, and a controller 120.

[0063] The communication module 110 communicates with the plurality of home appliances 210, 220, 230, 240.

[0064] The integrated water purifier 100 purifies raw water supplied through a feed valve 13 by internal filters 16, 17.

[0065] The plurality of supply valves 18, 20, 22, 23, 24 can supply the water purified by the integrated water purifier 100 to the plurality of home appliances 210, 220, 230, 240.

[0066] The pump 140 pumps raw water and supplies it to the feed valve 13.

[0067] The memory 130 stores the priorities of the plurality of home appliances 210, 220, 230, 240 and stores the water output reference values required by the plurality of home appliances 210, 220, 230, 240.

[0068] The controller 120 controls communication with the plurality of home appliances 210, 220, 230, 240 through the communication module 110 and controls the driving of the integrated water purifier 100.

[0069] When the first home appliance 210 among the plurality of home appliances 210, 220, 230, 240 inputs a selection of water, the controller 120 determines whether other home appliances 220, 230, 240 are using water. When at least one of the other home appliances 220, 230, 240 is using water, the controller 120 determines the priorities of the first home appliance 210 and the home appliance that is using water.

[0070] The controller 120 controls at least one of the feed valve 13, the first supply valve 22, and the second supply valve 23 according to the priorities to supply purified water to at least one of the plurality of home appliances 210, 220, 230, 240.

[0071] The controller 120 controls at least one of the standby operations of the plurality of home appliances 210, 220, 230, 240, the opening drive of the feed valve 13, and the opening drive of at least one of the plurality of supply valves 18, 20, 22, 23, 24 according to the priority. In addition, when the water output discharged to the plurality of home appliances 210, 220, 230, 240 is below the reference value, the controller 120 can drive the pump 140 to open.

[0072] As an example, when the priority of the first home appliance 210 that selects water is lower than that of the second home appliance 220 that is using water, the controller 120 controls the first home appliance 210 to perform a standby operation.

[0073] As an example, when the priority of the first home appliance 210 is higher than that of the second home appliance 220 that is using water, the controller 120 controls the standby operation of the second home appliance 220, the opening drive of the feed valve 13, and the opening drive of the first supply valve 22 corresponding to the first home appliance 210.

[0074] As an example, when the priority of the first home appliance 210 is such that it can be driven simultaneously with the second home appliance 220 that is using water, the controller 120 controls the opening drive of the feed valve 13 and the opening drives of the first supply valve 22 and the second supply valve 23 corresponding to the first home appliance 210 and the second home appliance 220. Here, the controller 120 can control the standby operations and pauses of the first home appliance 210 and the second home appliance 220 through the communication module 110.

[0075] The feed valve 13 supplies raw water into the integrated water purifier 100, and at least one of the filters 16, 17 filters the water supplied through the feed valve. The electrolyzed water module 19 electrolyzes the water purified by at least one of the filters 16, 17 to produce ionized water.

[0076] The pipe that conveys the water purified by at least one of the filters 16, 17 is connected to at least one of the plurality of supply valves 18, 23, 24, and the pipe that conveys the water purified by the filter 16 is connected to the supply valve 22.

[0077] As an example, the plurality of supply valves 18, 23, 24 are connected to the home appliances 220, 230, 240 that require water purified by the filters 16, 17, and the supply valve 22 is connected to the home appliance 210 that requires water purified by the filter 16.

[0078] The pipe that conveys the ionized water produced by the electrolyzed water module 19 is connected to the supply valve 20.

[0079] As an example, the supply valve 20 can be connected to a household appliance 240 that requires cleaning and washing water.

[0080] A description of the control method for the integrated water purification supply system configured as described above is as follows.

[0081] First, when the first household appliance 210 inputs a water selection during standby, the integrated water purification supply system determines whether other household appliances 220, 230, 240 are using water, and when the second household appliance 220 is using water, the integrated water purification supply system determines the priorities of the first household appliance 210 and the second household appliance 220.

[0082] Then, when the priority of the first household appliance 210 is higher than that of the second household appliance 220, the integrated water purification supply system drives the feed valve 13, the first supply valve 22, and the second supply valve 22 to open. At this time, the integrated water purification supply system can cause the second household appliance 220 to perform a standby operation or pause it through the communication module 110. If the first household appliance 210 finishes using water, the integrated water purification supply system will drive the second household appliance 220 that is in a standby operation to open.

[0083] Conversely, when the priority of the first household appliance 210 is lower than that of the second household appliance 220, the integrated water purification supply system controls the first household appliance 210 to perform a standby operation, and if the second household appliance 220 finishes using water, the integrated water purification supply system will drive the first household appliance 210 to open.

[0084] At this time, when the first household appliance 210 is in a standby operation due to the second household appliance 220 using water, the integrated water purification supply system can control the display unit of the first household appliance 210 or the user's smart terminal 300 to display that the first household appliance 210 is in a standby operation state for the user to identify.

[0085] As described above, the modular household appliance integrated water purification supply system includes a microcomputer control unit and controls communication with each household appliance in a wired and wireless manner, and controls the water supply valve based on this value and grasps the usage status of other household appliances.

[0086] If water is selected by each household appliance, a signal will be transmitted to the modular household appliance integrated water purification supply system, and the system will determine whether other household appliances are in use. If they are not in use, the feed valve will be opened and the product supply valves of each will be opened, so that clean water passing through the filter will be supplied to the household appliances.

[0087] If the system is being used for other products, the standby operation process or the necessary processes for simultaneous operation are controlled by grasping the priorities assigned to each product in advance, etc., and the pump can be controlled and operated as needed to supply an appropriate flow rate.

[0088] On the other hand, in the embodiment, the controller 120 can accumulate the usage frequencies of the first household appliance 210 and the second household appliance 220 within a specified time, and can automatically set the priorities according to the usage frequencies. In addition, at least one of the first household appliance 210 and the second household appliance 220 may further include an input unit for manually setting the priorities according to the user's selection. In addition, the priorities can be set based on whether it is drinking water or the usage frequency. As an example, the priorities can be set in the order of a water purifier (faucet, cooking water), a water purifier refrigerator, a coffee machine, a dishwasher, a beer brewing machine, or can be set in the order of a water purifier, a water purifier refrigerator, a coffee machine, a dishwasher, a beer brewing machine.

[0089] Figure 5 It is a flowchart showing the drive control of an integrated water purification supply system according to another embodiment. Figure 6 It is a table exemplifying the priorities of each household appliance.

[0090] Refer to Figure 3 and Figure 5 , when the first household appliance 210 inputs a selection of water during standby, the integrated water purification supply system determines whether other household appliances 220, 230, 240 are using water.

[0091] Then, the integrated water purification supply system determines the priorities of the plural household appliances 210, 220, 230, 240 that are using water.

[0092] As an example, the priorities can be set in the order of a water purifier (faucet, cooking water), a water purifier refrigerator, a coffee machine, a dishwasher, a beer brewing machine based on the usage frequency. Or, the priorities can be set in the order of a water purifier, a refrigerator, a coffee machine, a beer brewing machine, a dishwasher based on whether it is drinking water. Of course, this embodiment is not limited thereto, and can be variably implemented within the technical idea of this embodiment.

[0093] Then, the integrated water purification supply system determines whether it can operate simultaneously. As an example, in the case of household appliances with the same priority, the integrated water purification supply system can determine that the same operation can be performed. As another example, a set value that enables plural household appliances to operate simultaneously can be preset in advance, and it can be determined that they can be driven simultaneously with the corresponding set value.

[0094] Then, in the case where simultaneous operation is not possible, the integrated water purification supply system can control the home appliances with lower priority among the plurality of home appliances 210, 220, 230, and 240 to perform standby operation and pause, and display a message regarding this.

[0095] Then, in the case where simultaneous operation is possible, the integrated water purification supply system drives the supply valves of the corresponding home appliances to open simultaneously.

[0096] At this time, the integrated water purification supply system can additionally confirm whether the set water output is satisfied. As an example, in the case where the set water output is satisfied, the integrated water purification supply system closes the supply valve of the selected home appliance.

[0097] Then, the integrated water purification supply system closes the feed valve 130 and ends the water output.

[0098] As described above, in the case of repeated use according to each home appliance, the integrated water purification supply system requires priority operation. This is because errors occur in the product operation due to the inability to meet the required flow rate, or inconvenience is brought to consumers due to the inability to meet the driving performance of the product. Therefore, as shown below, it can be controlled to have priority based on the home appliances that use the most water and are frequently used.

[0099] From the perspective of the water usage mode of the integrated water purification supply system, the home appliances that are used most frequently can be sorted in the order of home appliances, for example, water purifier (faucet, cooking water) > water purifier refrigerator > coffee machine > dishwasher > beer brewing machine.

[0100] If the actions of each home appliance are input and water output is selected, it is determined whether other home appliances are in use. If they are in use, the preset priority is confirmed and it is determined whether it is a case where simultaneous operation is possible. This can be confirmed through pre-verified data and control the limited flow rate of the integrated water purification supply system to stably drive more than a certain number of products.

[0101] If it is a case where simultaneous operation is not possible due to more than the limited number of driven products, the products with lower preset priority pause operation and standby. At this time, the guiding message of the content in use / standby message can be displayed on the display. After that, if the operation of the home appliance with higher priority is completed, the supply valve is closed, and the operation of the previously stopped home appliance will start to be driven again in sequence. If the set operations of all home appliances are completed, the feed valve 13 is controlled to close and the modular home appliance integrated water purification supply system is stopped.

[0102] Refer to Figure 6 , the priority of each home appliance can be set so that a plurality of home appliances can operate simultaneously.

[0103] As an example, the priority of each household appliance device can be set in the order of a water purifier (faucet, cooking water), a water purifier refrigerator, a coffee machine, a dishwasher, and a beer brewing machine.

[0104] As an example, it can be set that the water purifier (faucet, cooking water) and the water purifier refrigerator can operate simultaneously, it can be set that the water purifier (faucet, cooking water) and the coffee machine can operate simultaneously, and it can be set that the water purifier (faucet, cooking water) and the beer brewing machine can operate simultaneously.

[0105] As an example, it can be set that the water purifier refrigerator and the coffee machine can operate simultaneously, it can be set that the water purifier refrigerator and the beer brewing machine can operate simultaneously, and it can be set that the coffee machine and the beer brewing machine can operate simultaneously.

[0106] As an example, the dishwasher can be set so that there is no household appliance device that can operate simultaneously.

[0107] As an example, if a water purifier request for water use is input during the operation of the dishwasher, the dishwasher can be made to perform a standby operation. If the water purifier finishes using water, purified water will be supplied to the dishwasher again and it will be made to operate.

[0108] Figure 7 It is a flowchart showing the drive control of an integrated water purification supply system according to another embodiment.

[0109] Referring to Figure 3 and Figure 7 , when a plurality of household appliance devices 200 including a water purifier, a faucet, cooking water, a refrigerator, a dishwasher, a coffee machine, a beer brewing machine, etc. are in a standby state, and when each household appliance device selects water output, the integrated water purification supply system drives the pump 140 to turn on.

[0110] Then, the integrated water purification supply system determines whether other household appliance devices are being used.

[0111] Then, when other household appliance devices are using water, the integrated water purification supply system determines the priority.

[0112] Then, the integrated water purification supply system determines whether they can operate simultaneously.

[0113] Then, when they cannot operate simultaneously, the integrated water purification supply system can control the household appliance device with a lower priority among the plurality of household appliance devices 210, 220, 230, 240 to perform a standby operation and pause, and display a message about it.

[0114] Then, when they can operate simultaneously, the integrated water purification supply system drives the supply valves of the corresponding household appliance devices to open simultaneously.

[0115] At this time, the integrated water purification supply system additionally confirms whether the set water output is satisfied.

[0116] When the set water output is satisfied, the integrated water purification supply system shuts off the drive of pump 140.

[0117] Then, the integrated water purification supply system closes the corresponding supply valve and feed valve 130 and ends the water output.

[0118] As an example, when the priority of the first household appliance 210 selected for water output is higher than that of the second household appliance 220 that is using water and they cannot be driven simultaneously, the integrated water purification supply system makes the second household appliance 220 perform a standby operation or pause, and drives the first supply valve 22 corresponding to the first household appliance 210 to open.

[0119] At this time, if the first household appliance 210 finishes using water, the integrated water purification supply system drives the second household appliance 220 that has performed the standby operation to start again. As an example, when a water purifier or coffee machine with a lower priority than a dishwasher in operation selects to use water, the water purifier or coffee machine can be given priority to operate, causing the dishwasher to pause. After the water purifier or coffee machine finishes using water, it is driven again.

[0120] As an example, when the priority of the first household appliance 210 is lower than that of the second household appliance 220, the integrated water purification supply system can control the first household appliance 210 to perform a standby operation. If the second household appliance 220 finishes using water, it drives the first household appliance 210 to start.
