At present, with the attention of people on the quality of drinking water, water purifiers have entered into a plurality of families. Wherein, the life of the filter element in the water purifier is a core component for determining the use cost of the water purifier. For example, for a water purifier provided with a RO (Reverse Osmosis) reverse osmosis membrane (RO membrane for short) cartridge, the most costly is the RO membrane cartridge. Typically, the set life of the RO membrane cartridge is typically 3 years. In the actual use process, the service life of the filter element can be influenced by factors such as water quality, and if the impurity ions in the water are relatively more, the service life of the filter element can be directly shortened.
In the embodiment provided by the invention, for the water supply system provided with the softening device, the heating device and the water purifying device at the same time, soft water can be provided to the heating device and the water purifying device by using the softening device. Because in this water supply system, this softening installation and purifier can make up the use, promptly through the water supply purifier of this softening installation softened water, in this in-process, this softening installation's sodium ion can filter through purifier, can not influence drinking water safety, simultaneously because the softening installation passes through ion exchange resin and gets into this softening installation's impurity ion quantity greatly reduced of calcium, magnesium ion in the water, can effectively improve the life of RO membrane filter core to reduce user's use cost.
The inventors found that: in the use process of the water supply system, a certain water consumption conflict problem can exist between the heating device and the water purifying device. For example, in a case, when the heating device is in a state of supplying hot water to the outside, at this time, the water purifying device is started to produce water, and since the soft water supply amount is constant, at this time, the water purifying device has a split-flow effect on the heating device, which may cause a problem that the temperature of the water discharged from the heating device fluctuates greatly, even a problem that flameout occurs, and the use experience of a user may be affected. In another case, if the water purifying apparatus is in a water producing state, the heating apparatus is started at this time, and the heating apparatus may have a split effect on the water purifying apparatus due to the constant supply of soft water, and may cause its malfunction. Further, in an extreme case, if the heating device and the water purifying device are started at the same time, only one of them may be started normally, or even neither of them may be started normally, possibly due to the limited supply of soft water.
As shown in fig. 1 to 2 and 4 to 11, in order to solve the problem of water collision of soft water of the heating device 3 and the water purifying device 200, the embodiment of the present invention provides a water supply system, which may include: a raw water supply line 10; a softening device 2, wherein a water inlet of the softening device 2 can be communicated with the raw water supply pipeline 10; the water inlet of the heating device 3 can be communicated with the water outlet of the softening device 2; a hot water supply line 40, the hot water supply line 40 being in communication with an outlet of the heating device 3; the inlet of the water purifying device 200 can be communicated with the water outlet of the softening device 2; a diversion mechanism 6, wherein the diversion mechanism 6 can divert the soft water flowing out of the softening device 2 to the heating device 3 and/or the water purifying device 200; the water purifying apparatus 200 includes a water filtering unit 210, and soft water flowing into the water purifying apparatus 200 can flow into the water filtering unit 210.
In this embodiment, the water supply system mainly includes core components including: softening device 2, heating device 3, water purifying device 200, and diversion mechanism 6. As shown in fig. 2, 5, 7, 9 and 11, the heating device 3, the softening device 2 and the diverting mechanism 6 may be integrally arranged, so as to facilitate integrated installation and save installation space. Of course, the heating device 3, the softening device 2, and the diversion mechanism 6 are not limited to the integrated arrangement, and may be separately mounted as shown in fig. 1, 4, 6, 8, and 10.
In the description of the present application, the heating device 3, the softening device 2 and the diverting mechanism 6 are mainly exemplified in the form of an integrated arrangement.
As shown in fig. 2 and 3, when the heating device 3, the softening device 2 and the diversion mechanism 6 are integrally disposed, they may be integrated into one water supply device 100, that is, the water supply system includes the water supply device 100, and the heating device 3, the softening device 2 and the diversion mechanism 6 are integrally disposed in the housing 110 of the water supply device 100.
The water supply device 100 integrates the softening device 2, the heating device 3, and the diversion mechanism 6, and can provide both heated and softened hot soft water and softened cold soft water. In the present description, the heating device 3 is mainly exemplified as a gas heating device, but those skilled in the art will recognize that the heating device 3 is not limited to a gas heating device, and may take other forms for heating water immediately, and the present application will not be described herein. The gas heating device may specifically be a heating device 3 in a device such as a wall-mounted furnace, a gas water heater, and the like, and the softening device 2 is integrated in the wall-mounted furnace, the gas water heater, and the like.
Referring to fig. 3, the water supply device 100 may include: a softening device 2 for softening water; a heating device 3 which can be communicated with the water outlet of the softening device 2; a water inlet part 1, wherein the water inlet part 1 can be communicated with a water inlet of the softening device 2; a first water outlet 4, wherein the first water outlet 4 can be communicated with a water outlet of the heating device 3 and a hot water supply pipeline 40; a second water outlet part 5, wherein the second water outlet part 5 can be communicated with a water outlet of the softening device 2 and the water purifying device 200; and the diversion mechanism 6 is used for communicating the water outlet of the softening device 2 with the water inlet of the heating device 3 and/or the second water outlet part 5.
The water supply device 100 includes a housing 110, the housing 110 is used for integrally mounting the softening device 2 and the heating device 3 in the same cavity, and the water inlet portion 1, the first water outlet portion 4 and the second water outlet portion 5 are disposed on the housing 110. Naturally, the housing 110 is provided with components such as the diversion mechanism 6 and necessary connection pipes in addition to the softening device 2 and the heating device 3.
Wherein the heating device 3 is mainly used for heating cold water flowing through the inside thereof. Specifically, the form of cold water which can be introduced into the heating device 3 for heating may be varied according to the connection and communication relationship of the specific pipes inside the water supply device 100, the water demand of the user, and the like. In this embodiment, the heating device 3 is connected to the water outlet of the softening device 2, and the cold water may be cold water softened by the softening device 2 and then flows out from the water outlet.
In particular, the heating device 3 may comprise a heat exchanger and a burner for providing said heat exchanger with heat energy. The heat exchanger can be a heat exchange tube type heat exchanger, and of course, the heat exchanger is not limited to the heat exchange tube type heat exchanger, and can also be an electric heating type heat exchanger and the like. In the embodiments of the present disclosure, the heat exchanger is exemplified by a heat exchange tube type heat exchanger, and other forms of heat exchangers may refer to this form, and the disclosure will not be repeated herein. When the heating device 3 works, high-temperature flue gas formed by combustion of the burner exchanges heat with a heat exchange pipe of the heat exchanger to heat water in the heat exchanger.
The water outlet of the heating device 3 may be connected to a first water outlet 4, and the first water outlet 4 may be communicated with the water outlet of the heating device 3, that is, water flowing out from the water outlet of the heating device 3 may flow to the first water outlet 4, and may be supplied to a user through a hot water supply pipeline 40. Specifically, the first water outlet 4 may be in the form of a joint provided on the housing 110 for externally connecting the supply line 40 to provide the user with the hot soft water. When the first water outlet portion 4 is in the form of a joint, the first water outlet portion 4 and the water outlet of the heating device 3 may be directly connected, or may be connected by an intermediate pipeline, or may also be communicated by an integrated waterway module. It is needless to say that the first water outlet 4 is not limited to other forms, for example, a form of a connecting pipe with a joint, and the like.
The softening device 2 is mainly used for softening cold water flowing through the interior thereof. The cold water may be normal-temperature tap water flowing in from the water inlet portion 1. Specifically, the softening device 2 includes a resin tank in which a softening resin is stored. Further, the softening device 2 may further include a salt tank structure storing soft water salt, a first solenoid valve and a second solenoid valve provided upstream of the resin tank, and the like. Wherein, when soft water is normally used, the second electromagnetic valve is opened, and the first electromagnetic valve is closed; in the resin regeneration process, the resin tank has no softening capacity, and the regeneration process can conflict with the use of soft water, and if a user has water demand at this time, the first electromagnetic valve is opened and the second electromagnetic valve is closed when the user does not walk the resin tank any more. The water outlet of the softening device 2 is connected with a second water outlet part 5, and the second water outlet part 5 can be communicated with the water outlet of the softening device 2, namely, soft water flowing out of the water outlet of the softening device 2 can flow to the second water outlet part 5. Specifically, the second water outlet 5 may be in the form of a joint disposed on the housing 110 for connecting with other water consuming devices requiring soft water to provide soft water to the user. For example, the second water outlet 5 may be communicated with the water purifying device 200 at the same time as the second water outlet 5 is communicated with the water outlet of the softening device 2, so that the soft water discharged from the softening device 2 is supplied to the water purifying device 200. When the second water outlet portion 5 is in the form of a joint, the second water outlet portion 5 and the water outlet of the softening device 2 may be directly connected, or may be connected by an intermediate pipeline, or may be connected by an integrated waterway module. It is needless to say that the second water outlet 5 is not limited to other forms, for example, a form of a connecting pipe with a joint, and the like.
The water inlet of the softening device 2 is connected with a water inlet part 1, the water inlet part 1 can be communicated with the water inlet of the softening device 2 and a raw water supply pipeline 10, and tap water can flow to the water inlet of the softening device 2 through the raw water supply pipeline 10 and the water inlet part 1. Specifically, the water inlet portion 1 may be in the form of a joint provided on the housing 110 to supply tap water to the softening device 2. When the water inlet part 1 is in the form of a joint, the water inlet part 1 and the water inlet of the softening device 2 can be directly connected, or can be connected by an intermediate pipeline, or can be communicated by an integrated waterway module. It is needless to say that the water inlet portion 1 is not limited to other forms, for example, a form of a connecting pipe with a joint, and the like.
The water supply device 100 is provided with a diversion mechanism 6, and the diversion mechanism 6 can divert the soft water flowing out of the softening device to at least one of the heating device 3 and the water purifying device 200. Specifically, the diversion mechanism 6 is configured to communicate the water outlet of the softening device 2 with the water inlet of the heating device 3 and the second water outlet portion 5, and after the water softened by the softening device 2 flows out from the water outlet, the water flows through the diversion mechanism 6 and then can flow to the water inlet of the heating device 3 and the second water outlet portion 5.
Wherein, the diversion mechanism 6 can be positioned at the water outlet of the softening device 2 or connected to a communication water path between the water outlet of the softening device 2 and the water inlet of the heating device 3. The communication waterway is located in the housing 110 of the water supply device 100.
In the embodiment of the present specification, the flow dividing mechanism 6 may include a three-way structure; in addition, the flow dividing mechanism 6 can also superimpose the flow adjusting/distributing function on the basis of a three-way structure. For example, the flow dividing mechanism 6 may be a flow distribution valve provided with three openings; alternatively, the flow rate adjusting valve 7 may be a three-way structure and may be disposed between the second outlet 62 and the second water outlet 5 or between the first outlet 61 and the heating device 3 (when the second water outlet 5 is connected to the inlet 60 of the water purifying device 200 via a pipe, between the second outlet 62 and the water purifying device 200 and/or between the first outlet 61 and the heating device 3). Optionally, the flow regulating valve 7 may be a valve with a switch function, a valve with a multi-gear regulating function, or a valve with stepless regulation and on-off function.
When the flow dividing mechanism 6 is at least of a three-way construction, in particular, the flow dividing mechanism 6 has an inlet 60, a first outlet 61 and a second outlet 62. The inlet 60 is connected to the water outlet of the softening device 2, and the first outlet 61 and the second outlet 62 are respectively connected to the water inlet of the heating device 3 and the second water outlet 5. For the water supply system provided with the water purifying device 200, the inlet 60 is connected to the water outlet of the softening device 2, and the first outlet 61 and the second outlet 62 are respectively connected to the water inlet of the heating device 3 and the inlet of the water purifying device 200.
Alternatively, as shown in fig. 3, the diversion mechanism 6 has an inlet 60, a first outlet 61 and a second outlet 62, the inlet 60 is connected to the water outlet of the softening device 2 through a part of the communication waterway, and the first outlet 61 and the second outlet 62 are respectively communicated to the water inlet of the heating device 3 and the second water outlet 5. For the water supply system provided with the water purifying device 200, the inlet 60 is connected to the water outlet of the softening device 2 through a part of the communication waterway, and the first outlet 61 and the second outlet 62 are respectively communicated to the water inlet of the heating device 3 and the inlet of the water purifying device 200.
When the splitting mechanism 6 includes three opening flow distribution valves, the flow distribution valves may be, in particular, PSG valves, or other valves having a flow regulating function, which are capable of regulating the flow rate of the soft water entering from the inlet 60 to the first and second outlets 61 and 62 by adjusting the opening degree of the communication of the inlet 60 with the first and second outlets 61 and 62.
When the flow dividing mechanism 6 includes a combination of a three-way structure and flow regulating valves 7, the number of the flow regulating valves 7 may be one, two, or even more. Referring to fig. 4 or 5, for example, the number of the flow rate adjusting valves 7 may be one, which may be disposed between the second outlet 62 and the second water outlet 5. For a water supply system provided with the water purifying device 200, the flow regulating valve 7 may be provided between the second outlet 62 and the water purifying device 200. When the flow rate regulating valve 7 is in the on state, the soft water may flow from the diversion mechanism 6 to the second water outlet 5 and further to the water purifying apparatus 200. Of course, the specific form of the flow rate regulating valve 7 may be a form of a switching valve or a form of a regulating valve whose opening degree is adjustable, that is, a form of a regulating valve capable of realizing a multistage regulation or a stepless regulation of the flow rate, and the present application is not limited in form herein.
In addition, the flow rate regulating valve 7 may be provided between the first outlet 61 and the heating device 3, and soft water may flow from the diversion mechanism 6 to the heating device 3 when the flow rate regulating valve 7 is in a conductive state. The number of the flow rate control valves 7 may be plural, and the flow rate control valves 7 may be provided between the second outlet 62 and the second water outlet 5, and between the first outlet 61 and the heating device 3, respectively, so that the flow rate control of the two independent branches is realized.
The water purifying apparatus 200 includes a water filtering unit 210, and soft water flowing into the water purifying apparatus 200 can flow into the water filtering unit 210. Specifically, the water filtering unit 210 includes a membrane element, and the soft water flowing into the water filtering unit 210 flows out of the water filtering unit 210 after being filtered by the membrane element.
Wherein the membrane element may comprise a reverse osmosis membrane element. Of course, the form of the membrane element is not limited to the above examples, and it may be other forms or a combination with other forms, for example, the membrane element may further include any one of or a combination of micro-filtration membrane, nano-filtration membrane, and the like. When the membrane element comprises a reverse osmosis membrane element, dissolved salts, colloids, microorganisms, organic matters and the like in water can be effectively removed because the membrane pore diameter of the reverse osmosis membrane is very small (the diameter of surface micropores is generally between 0.5 and 10 nm).
In one embodiment, the water purifying apparatus 200 further includes a heat tank 230 for storing the heated purified water. When the water purifying device 200 is provided with the hot tank 230, a certain amount of purified water with the water temperature of the set temperature is stored in advance for a user, and no matter whether the water purifying device 200 is in a water producing state or not, the purified water can be directly provided for the user as long as the hot tank 230 also stores water, so that the requirement of the user for using hot water at any time can be met.
In the water supply device 100, the water inlet portion 1 for inputting cold water is the total water inlet of the water supply device 100, and communicates with the raw water supply line 10. If the water supply device 100 starts the water purifying device 200 to produce water in a state where the heating device 3 heats soft water, the water flow rate entering the heating device 3 will fluctuate due to the diversion effect of the water purifying device 200 under the condition that the total inflow rate is not changed, so that the fluctuation of the temperature of the hot water outputted from the first water outlet 4 is obvious. If the heating device 3 is activated to heat soft water in the water supply device 100 in a state where the water purifying device 200 is producing water, the normal water production of the water purifying device 200 may be affected due to the split flow of the heating device 3 in a case where the total inflow rate is not changed.
In order to solve the water collision between the heating device 3 and the water purifying device 200, at least one of the communication pipeline between the first outlet 61 of the split mechanism 6 and the heating device 3 and the communication pipeline between the second outlet 62 and the water purifying device 200 may be controlled to be on-off or the flow may be distributed based on the total inflow water flow and the flow information that can be split to the heating device 3 and the water purifying device 200, so as to solve the water collision between the two.
In one embodiment, the water supply system may further include a first flow rate detecting unit 91, a second flow rate detecting unit 92, and a controller (not shown in the drawing) electrically connected to the first flow rate detecting unit 91 and the second flow rate detecting unit 92, the first flow rate detecting unit 91 and the second flow rate detecting unit 92 being capable of detecting any two of a flow rate of the raw water supply line 10, a flow rate of the raw water flowing through the heating device 3, and a flow rate of the raw water flowing toward the water purifying device 200, the controller being capable of controlling a flow direction of the soft water flowing out of the softening device 2 according to a detection result of the first flow rate detecting unit 91 and the second flow rate detecting unit 92.
When the softening device 2, the heating device 3, the diverting mechanism 6, etc. in the water supply system are integrally provided in the same housing 110 to form the water supply device 100, the controller, the first flow detecting unit 91, the second flow detecting unit 92 may be located in the water supply device 100. Accordingly, the water supply device 100 further includes a first flow rate detecting unit 91, a second flow rate detecting unit 92, and a controller electrically connected to the first flow rate detecting unit 91 and the second flow rate detecting unit 92, the first flow rate detecting unit 91 and the second flow rate detecting unit 92 being capable of detecting any two of the flow rate of the raw water supply pipe 10, the flow rate flowing through the heating device 3, and the flow rate flowing to the water purifying device 200, and the controller being capable of controlling the flow direction of the soft water flowing out of the softening device 2 according to the detection results of the first flow rate detecting unit 91 and the second flow rate detecting unit 92.
Specifically, the first flow rate detecting unit 91 may be disposed near the water inlet portion 1, for detecting the flow rate of the raw water supply line 10; the second flow rate detecting unit 92 may be provided in a line between the first outlet 61 and the water inlet of the heating device 3 or in a line between the outlet of the heating device 3 and the water supply line for supplying the hot water to the outside for detecting the flow rate flowing through the heating device 3; the controller is electrically connected to the first flow detecting unit 91 and the second flow detecting unit 92, respectively, and is configured to control the flow direction of the soft water flowing out of the softening device 2 according to the detection results of the first flow detecting unit 91 and the second flow detecting unit 92. It should be noted that "flow direction" herein means a flow direction of a liquid when there is a flow rate of the liquid in a pipe, for example, a section of the pipe has the liquid but the liquid does not flow (for example, a valve in an off state exists in the pipe or the pipe is connected to a valve in an off state), at which time the flow rate in the pipe is 0, and the liquid does not flow in the pipe and thus there is no flow direction.
In the present embodiment, the controller may acquire the total inflow water flow and the first water flow split to the heating device 3 according to the first flow detection unit 91 and the second flow detection unit 92, respectively; further, the second water flow rate diverted to the second water outlet portion 5 may be determined based on the inflow water flow rate and the first water flow rate, so that the flow direction of the soft water flowing out of the softening device 2 is controlled based on the diversion situation and the water demand of the heating device 3 and the water purifying device 200, etc.
It should be noted that: in the embodiments of the present application, the specific number and positions of the flow rate detecting units are merely typical examples, and those skilled in the art can adaptively adjust the flow rate detecting units according to actual pipeline conditions and the like. For example, when the number of the flow rate detection units is two, the flow rate detection units may be respectively provided at the water inlet portion 1 and the second water outlet portion 5, so that the total water inlet flow rate and the second water flow rate split to the second water outlet portion 5 are respectively obtained, and the first water flow rate split to the heating device 3 may be determined based on the water inlet flow rate and the second water flow rate; alternatively, a flow rate detection unit or the like for detecting the flow rate of water flowing through the heating device 3 and obtaining the flow rate of water from the second water outlet portion 5 may be provided, respectively. In principle, the total inflow flow, the first water flow split to the heating device 3 and the second water flow split to the second water outlet 5 can be determined by flow detection at any two positions. Here, the description will not be given for other cases. When the number of the flow rate detection units is three, the flow rate detection units can be arranged at the three positions, so that the water inflow rate, the first water flow rate which is branched to the heating device 3 and the second water flow rate which is branched to the second water outlet part 5 can be directly obtained.
In some cases, when the flow rate of soft water that the softening device 2 can provide is limited (for example, it is impossible to simultaneously ensure that the heating device 3 and the water purifying device 200 can be in an operating state), in order to ensure that the heating device 3 is in an operating state for heating soft water, that is, when the water purifying device 200 can normally produce water while heating soft water, a branch pipe 80 (as shown in fig. 8, 9, 10 and 11) may be provided to supply a portion of raw water in an original supply pipe to the water purifying device 200, thereby ensuring the flow rate of soft water flowing into the heating device 3.
In one embodiment, the water supply system may further include a water inflow diversion unit 81, the water inflow diversion unit 81 being for diverting the inflow water of the raw water supply line 10 to the water inlet of the softening device 2 and/or the inlet of the water purification device 200.
For the embodiment provided with the water supply device 100, the water inflow branching unit 81 may be integrally provided in the housing 110 of the water supply device 100. Specifically, the water supply device 100 further includes a water inlet diversion unit 81, where the water inlet diversion unit 81 is configured to divert the water inlet of the water inlet portion 1 to the water inlet of the softening device 2 and/or the second water outlet portion 5.
In particular, the inflow branching unit 81 may be in the form of a tee having an inlet connected to the raw water supply line 10 and two outlets respectively connectable to the water inlet of the softening device 2 and the inlet of the water purifying device 200. Of course, the water inlet and distribution unit 81 may also be a cavity structure formed inside the waterway integrated module and at least includes three interfaces, and of course, the water inlet and distribution unit 81 may also be other forms, which are not limited in detail herein.
Further, a bypass valve 82 may be connected between the water inlet and outlet unit 81 and the second water outlet portion 5, and when the bypass valve 82 is in a conducting state, part of water provided by the water inlet and outlet unit 81 may flow to the second water outlet portion 5.
Referring to fig. 8 and 9, in particular, the bypass valve 82 may be provided in the branch pipe 80 between the water inlet branching unit 81 and the second water outlet pipe. In the water supply system provided with the water purifying device 200, a bypass valve 82 is connected between the water inlet diversion unit 81 and the water purifying device 200, and a portion of the raw water supplied from the raw water supply pipe 10 flows to the water purifying device 200 when the bypass valve 82 is in a conductive state.
When the bypass valve 82 is provided on the branch pipe 80, it cooperates with the flow regulating valve 7 provided between the second outlet 62 and the water purifying device 200 to ensure that a portion of the raw water flows only to the water purifying device 200. When the flow regulating valve 7 is in the off state and the bypass valve 82 is in the on state, only raw water flowing from the water inflow branching unit 81 into the branching piping 80 can flow to the water purifying apparatus 200 without soft water flowing into the water purifying apparatus 200; when the flow rate adjusting valve 7 is in the on state and the bypass valve 82 is in the off state, only soft water flows into the water purifying device 200 and no raw water flows into the water purifying device 200. Similarly, when the softening device and the heating device are integrated in the same housing, the branch pipe 80 and the water inlet and distribution unit 81 may also be located outside the housing, the branch pipe 80 is connected to the water purifying device 200, and the bypass valve 82 on the branch pipe 80 is matched with the flow regulating valve 7 between the distribution mechanism 6 and the second water outlet 5.
Referring to fig. 10 and 11, in combination with the scheme of providing the branch pipe 80 and the water inlet splitting unit 81, the flow rate adjusting valve 7 may be disposed at a connection position of the branch pipe 80 and the second water outlet pipe (i.e., between the second outlet 62 and the water purifying device 200) when the flow rate adjusting valve 7 is disposed between the second outlet 62 and the water purifying device 200.
The flow regulating valve 7 may be in the form of a flow regulating valve having three openings, and may open one of the openings opposite to the branch pipe 80 to conduct the branch pipe 80 and close the other opening opposite to the heating device 3 to prevent raw water from entering the heating device 3 when it is required to ensure that part of the raw water only flows to the water purifying device 200.
Of course, in some embodiments, in the embodiment where the branch pipe 80 is provided, a flow rate adjusting valve or a switching valve may be additionally provided between the second outlet 62 and the heating device 3, and when the bypass valve 82 is opened, the flow rate adjusting valve or the switching valve is closed, so as to prevent raw water from entering the heating device 3, i.e. ensure that raw water only enters the water purifying device 200.
In one embodiment, the water purification apparatus 200 may further include a water inlet valve 220 disposed on a water inlet line 240 of the water purification apparatus 200.
The inlet valve 220 can at least control the on-off of the inlet line 240. When the water inlet valve 220 is opened, the soft water supplied from the softening device 2 or the raw water supplied from the raw water supply line 10 can be supplied to the water purifying device 200 through the water inlet line 240.
It should be noted that although the water purifying apparatus 200 includes the water inlet valve 220 as shown in fig. 4 to 5 and 8 to 9, since the flow regulating valve 7 is provided between the flow dividing mechanism 6 and the water purifying apparatus 200, the water purifying apparatus 200 may not have the water inlet valve 220, and water supply to the water purifying apparatus 200 or stop water supply may be realized by the flow regulating valve 7.
As shown in fig. 6 to 11, in one embodiment, the water supply system may further include a booster pump 93 provided on the raw water supply line 10, and the booster pump 93 may be activated to be in an operating state when both the heating device 3 and the water purifying device 200 are in an operating state. In case that the branch pipe 80 and the inflow water diversion unit 81 are provided, the booster pump 93 may be located on the raw water supply pipe 10 downstream of the inflow water diversion unit 81.
In the present embodiment, a booster pump 93 may be provided in the raw water supply line 10. After the booster pump 93 is started, the water pressure and flow rate of raw water entering the softening device 2 can be increased by using the booster pump 93, so that the system can be ensured to be respectively provided for the heating device 3 and the water purifying device 200 which are in working states by enough flow rates, the flow rate compensation effect can be achieved, and the water temperature fluctuation of hot water generated by the heating device 3 can be weakened.
For example, when the heating device 3 is in an operating state for heating soft water, the water purifying device 200 is started to produce water, and when the flow rate of soft water supplied from the softening device 2 is constant, the flow rate of soft water flowing into the heating device 3 is reduced due to the diversion of soft water by the water purifying device 200, and at this time, when the load is constant, the outlet water temperature of the heating device 3 fluctuates. In this embodiment, the booster pump 93 is provided to increase the soft water flow rate of the softening device 2, so that the water purifier 200 can shunt the heating device 3 to ensure the soft water flow rate to the heating device 3 to be stable, and the water outlet temperature of the heating device 3 is always controlled within a smaller temperature difference range.
It should be noted that the water supply system may further include a water pressure detecting unit, which may be provided in the raw water supply line 10 and may be located downstream of the booster pump 93 in the water flow direction, for detecting the water pressure of the raw water pressurized by the booster pump 93. The water pressure detecting unit may be equivalent to a flow rate detecting unit provided at the water inlet portion 1. When the water pressure of the water pressure detecting unit reaches the set pressure, the flow rate corresponding to the supply of the softening device 2 can also satisfy the requirement that the heating device 3 (heating soft water) and the water purifying device 200 (preparing purified water) are operated simultaneously. Of course, the manner of obtaining the flow in the system is not limited to the above examples, and those skilled in the art can also use other existing manners to achieve the flow obtaining in the light of the disclosure of the present application.

In the present embodiment, according to the above-described water supply system embodiment, the water supply system is provided with: raw water supply pipeline, softening device, heating device, water purifier and diversion mechanism. The specific components of the water supply system, the connection of the various parts, the functions that can be implemented, etc. may refer to the specific description of the embodiments of the water supply system, and the present application is not repeated herein.
In the present embodiment, raw water flowing in from the soft water supply line may flow into the softening device. Specifically, a control device, such as at least one on-off valve or the like, may be provided on the raw water supply line, and when the on-off valve is opened, water in the raw water supply line may flow into the softening device.
The water softened by the softening device can flow to at least one of the heating device and the water purifying device according to the conditions of use requirements, flow and the like. For example, a diversion mechanism may be provided in a passage of the softening device communicating with the heating device and the water purifying device, by which diversion mechanism the diversion of the soft water flowing out of the softening device may be controlled.
Further, in some embodiments, the control method of the water supply system further includes obtaining at least one of a flow rate of soft water flowing through the raw water supply line and a flow rate of soft water flowing through the water purifying device.
That is, at the time of obtaining the flow rate, at least two of the flow rate of the raw water flowing through the raw water supply line, the flow rate flowing through the heating device, and the flow rate flowing to the water purifying device may be obtained. The specific manner of obtaining the flow may refer to the specific description of the water supply system, and the disclosure is not repeated herein.
The flow rate of the raw water flowing through the raw water supply pipeline, the flow rate flowing through the heating device and the flow rate flowing to the water purifying device are obtained, and the other flow rate can be calculated. That is, two of the flow rate of the raw water flowing through the raw water supply line, the flow rate of the heating device, and the flow rate of the water purifying device are obtained, which corresponds to all of the flow rates of the raw water flowing through the raw water supply line, the flow rate of the heating device, and the flow rate of the water purifying device.
Based on the flow condition, the flow (the flow of raw water) condition of the supply (the flow of raw water) can be reflected, so that the running states of the heating device and the water purifying device are controlled according to the acquired flow, the problem that a certain water conflict exists between the heating device and the water purifying device in the use process of the water supply system is solved, soft water of the softening device is reasonably distributed to different water equipment, the use requirements of the heating device in the water supply device and the water purifying device thereof are met, and the comprehensive use experience of a user is improved.
Wherein, the operation state of the heating device mainly comprises: the flow rate flowing through the heating device is larger than or equal to the starting flow rate of the heating device, and the soft water is heated so as to output the state of the soft water to a user; the flow rate through the heating device is smaller than the start-up flow rate of the heating device, thereby outputting a state of a smaller flow rate of cold soft water to the user, and the like. The running state of the water purifying device mainly comprises: the flow rate of the soft water flowing to the water purifying device is larger than or equal to the starting flow rate of the water purifying device, and the water purifying device can normally produce water based on the soft water; the flow rate of the hard water flowing to the water purifying device is larger than or equal to the starting flow rate of the water purifying device, and the water purifying device can normally produce water based on the hard water. It should be noted that the above description of the operation state of the heating device and the operation state of the water purifying device is only exemplary, and the present application is not limited to the above description, and may include any other reasonable operation state. In addition, when the water purifying device does not have water flowing in from the inlet thereof, it may indicate that the water purifying device cannot produce water; when the water purifying apparatus includes a tank capable of containing cold water, hot water, and warm water, the tank of the water purifying apparatus can output water stored therein even if no water flows in from an inlet thereof, which is also an operation state of the water purifying apparatus including the water storage tank.
In one embodiment, when the flow rate of the raw water flowing through the heating device is greater than or equal to the starting flow rate of the heating device and the flow rate of the raw water is smaller than the preset total flow rate, if the water purifying device receives the starting water making information, one of the heating device and the water purifying device is controlled to be in an operation state.
In this embodiment, when the flow rate flowing through the heating device is greater than or equal to the start-up flow rate of the heating device, it means that the heating device is turned on at this time; at this time, if the water purifying device receives the starting water making information, that is, the water purifying device needs to split the soft water output by the softening device, when the flow of raw water is smaller than the preset total flow, the total flow of the soft water supply side is insufficient to meet the requirement that the heating device heats the soft water and meanwhile the water purifying device makes water based on the soft water. Under the working conditions, one of the heating device and the water purifying device can be ensured to normally operate, and the other one is not operated. Normal operation here means: the heating device may output hot soft water, or the water purifying device may make water based on soft water. The value of the preset total flow can be set according to the water pressure of a general user, and the application is not limited in particular.
Under the working conditions, if the heating device and the water purifying device have use requirements, one of the heating device and the water purifying device can be controlled to be in a normal running state in order to ensure that the heating device and the water purifying device do not collide when in use, namely, the normal running state of the heating device can be maintained according to the design requirements, and soft water is heated and then is output outwards; or the operation of the heating device is suspended, the water purifying device is controlled to enter an operation state, and the soft water is processed by the filtering unit, so that purified water is output outwards.
In a specific embodiment, when the flow rate flowing through the heating device is greater than or equal to the starting flow rate of the heating device and the flow rate of the raw water is less than the preset total flow rate, if the water purifying device receives the starting water making information, the heating device is maintained in an operating state, and the soft water flowing out of the softening device is controlled to flow into the heating device only.
In this embodiment, if the heating device is operated normally under the above-mentioned working conditions, it is ensured that the user can continuously use the hot soft water for a period of time (for example, during a bath), and the heating device can be maintained in an operating state all the time. If the water purifying device receives the starting water making information in the operation process of the heating device, the heating device is maintained in an operation state, and soft water flowing out of the softening device is controlled to flow into the heating device only, so that a user is ensured to have comfortable water use experience; at this time, the water purifying device is not operated.
In another specific embodiment, when the flow rate of the raw water flowing through the heating device is greater than or equal to the starting flow rate of the heating device and the flow rate of the raw water is less than the preset total flow rate, maintaining the heating device in an operating state, and controlling the soft water flowing out of the softening device to flow into the heating device only; and controlling part of raw water in the raw water supply pipeline to flow into the water purifying device and starting the water purifying device to produce water.
In this embodiment, if the heating device is operated normally under the above-mentioned working conditions, it is ensured that the user can continuously use the hot soft water for a period of time (for example, during a bath), and the heating device can be maintained in an operating state all the time. If the water purifying device receives the start-up water making information during the operation of the heating device, at this time, in order to ensure that the water purifying device can make water and not split soft water, as shown in fig. 8 to 11, the splitting action of the water inlet splitting unit can be used to control part of the raw water in the raw water supply pipeline to flow into the water purifying device and start the water purifying device to make water.
In one embodiment, when the flow rate of the raw water flowing through the heating device is greater than or equal to the starting flow rate of the heating device and the flow rate of the raw water is greater than or equal to the preset total flow rate, if the water purifying device receives the starting water making information, controlling the soft water flowing out of the softening device to flow into the heating device and the water purifying device; and controlling the combustion load of the heating device to enable the water temperature flowing out of the heating device to reach a preset temperature range, and controlling the water purifying device to be in an operating state.
In this embodiment, when the flow rate of raw water is greater than or equal to the preset total flow rate, it means that the total flow rate at the soft water supply side at this time can satisfy the demand that the heating device heats soft water while the water purifying device produces water based on soft water. And when the flow rate flowing through the heating device is greater than or equal to the starting flow rate of the heating device, the heating device is started at the moment, and the heating device can be normally started to heat the soft water.
Under the second working condition (namely, the flow flowing through the heating device is greater than or equal to the starting flow of the heating device and the flow of raw water is greater than or equal to the preset total flow), if the heating device and the water purifying device have use requirements, the heating device and the water purifying device can normally enter the running state in theory. When the heating device is in an operating state, if the water purifying device has a water making requirement at the moment, under the condition that the total flow is unchanged, certain diversion can exist for the water flow possibly entering the heating device, and in order to slow down the water temperature fluctuation of the diversion to the hot soft water output by the heating device as much as possible, the combustion load of the heating device can be regulated, so that the water temperature flowing out of the heating device reaches the preset temperature range.
In one embodiment, when the flow rate flowing to the water purifying device is greater than or equal to the start flow rate of the water purifying device, the heating device receives the start information, and if the flow rate flowing through the heating device is greater than 0 and less than the start flow rate of the heating device and the flow rate flowing to the water purifying device is greater than or equal to a first preset flow rate, the soft water flowing out of the softening device is maintained to flow into the heating device and the water purifying device. Wherein, the first preset flow is greater than the starting flow of the water purifying device.
In this embodiment, during a normal operation state of the water purifying device (i.e., a flow rate flowing to the water purifying device is greater than or equal to a start-up flow rate of the water purifying device), if the heating device receives start-up information (the start-up information may be that a user opens a faucet in communication with the heating device), at this time, the flow rate flowing through the heating device may be determined; if the flow rate flowing through the heating device is smaller than the starting flow rate of the heating device, the heating device cannot be started by the current flow rate flowing through the heating device, and at the moment, the household water pressure of a user is possibly smaller, and the water purifying device can not be too large although operating normally; it is also possible that the user's home water pressure is large, the water purification device is operating normally and the flow is not too small, the user may have opened the cold water side of the domestic faucet or restricted the flow of the faucet to be so small that it is unable to fire normally, cold water is being used, and there is no actual hot water demand.
If it is further judged that the flow rate flowing through the water purifying device is greater than or equal to the first preset flow rate, the fact that the household water pressure of the user is normal or large is indicated, and the heating device cannot ignite because the user does not need to use the hot water is indicated. At this time, it is possible to maintain the inflow of the soft water flowing out of the softening device into the heating device and the water purifying device, the heating device does not heat and outputs a small flow of cold water, and the water purifying device operates normally and has a large flow. The specific value of the first preset flow is different according to the specific model, performance, etc. of the water purifying device, and the present application is not limited herein.
In one embodiment, when the water purifying device is in a normal operation state, the heating device receives the start-up information, and if the flow rate flowing through the heating device is greater than 0 and less than the start-up flow rate of the heating device and the flow rate flowing to the water purifying device is less than a first preset flow rate, the soft water flowing out of the softening device is controlled to flow into the heating device only.
In this embodiment, if the heating device receives the start-up information (the start-up information may be that a user opens a faucet connected to the heating device) while the water purifying device is in an operation state, the flow rate flowing through the heating device may be determined; if the flow rate flowing through the heating device is smaller than the starting flow rate of the heating device, the heating device cannot be started by the current flow rate flowing through the heating device, and at the moment, the household water pressure of a user is possibly smaller, and the water purifying device can not be too large although operating normally; it is also possible that the user's home water pressure is large, the water purification device is operating normally and the flow is not too small, the user may have opened the cold water side of the domestic faucet or restricted the flow of the faucet to be so small that it is unable to fire normally, cold water is being used, and there is no actual hot water demand.
If the flow rate flowing through the water purifying device is further judged to be smaller than the first preset flow rate, the water purifying device indicates that the household water pressure of the user is smaller, and the flow rate of the water purifying device is not too large although the water purifying device normally operates. At this time, in order to ensure the preferential operation of the heating means, it is possible to control the soft water flowing out of the softening means to flow only into the heating means, attempting to start the heating means for heating while suspending the operation of the water purifying means.
In one embodiment, when the water purifying device is in a normal operation state, the heating device receives the start-up information, and if the flow rate flowing through the heating device is greater than or equal to the start-up flow rate of the heating device, the soft water flowing out of the softening device is maintained to flow into the heating device and the water purifying device.
In this embodiment, if the heating device receives the start-up information (the start-up information may be that a user opens a faucet connected to the heating device) during the normal operation of the water purifying device, the flow rate flowing through the heating device may be determined; if the flow rate flowing through the heating device is greater than or equal to the starting flow rate of the heating device, it means that the heating device can be normally started by using the current flow rate flowing through the heating device itself, at this time, it is possible to maintain the flow of soft water flowing out of the softening device into the heating device and the water purifying device, i.e., the heating device can normally generate hot water, and the water purifying device can normally produce water based on the soft water.
For embodiments that only acquire flow through the heating device, it may include several specific scenarios as follows:
when the heating device is operated, if the water purifying device receives the starting water making information, and the flow rate flowing through the heating device is detected to be larger than or equal to the second preset flow rate, the soft water flowing out of the softening device is controlled to flow to the heating device and the water purifying device.
When the heating device is operated, if the water purifying device receives the starting water making information and detects that the flow rate flowing through the heating device is smaller than the second preset flow rate, the soft water flowing out of the softening device is controlled to flow to the heating device only.
For the above scenario, two different scenarios can be distinguished. For the first case, if the water purifying device does not have a communication module, the water purifying device cannot communicate with the controller in time, the water purifying device receives the starting water making information and cannot send the starting water making information to the controller in time, at this time, after the soft water needs to flow through the water purifying device for a period of time, the influence of the diversion of the water purifying device on the heating device is judged, at this time, the second preset flow can be the starting flow of the heating device. For the second case, if the water purifying device is provided with a communication module, the water purifying device can timely send the start-up water making information to the controller after receiving the start-up water making information, at this time, the water purifying device has not yet generated flow, the flow passing through the heating device is equal to the total flow, the second preset flow can be set to be flow capable of supporting the simultaneous use of the heating device and the water purifying device, for example, the sum of the start-up flow of the heating device and the start-up flow of the water purifying device is greater than or equal to the sum of the start-up flow of the heating device, and the running states of the heating device and the water purifying device can be controlled by measuring the flow passing through the heating device. The first case will be specifically described below as an example.
When the heating device has a use requirement, if the water purifying device is also required to produce water at the moment, the soft water flow rate of the heating device can be judged firstly after the water purifying device is started, if the soft water flow rate of the heating device is detected to be larger than or equal to the starting flow rate of the heating device at the moment, a certain margin is provided for the soft water flow rate provided by the softening device besides ensuring the normal ignition starting of the heating device, the split flow after the water purifying device is started does not influence the output of hot water of the heating device, and the soft water flow direction of the softening device can be controlled to the heating device and the water purifying device at the moment; if the soft water flow of the heating device is detected to be smaller than the starting flow of the heating device, the soft water flow provided by the softening device is insufficient to ensure that the heating device is started by normal ignition, and the split flow after the water purifying device is started influences the output of hot water by the heating device, so that the soft water of the softening device can be preferentially ensured to flow to the heating device. In addition, in order to ensure that the heating device is normally ignited and started, the flow rate of soft water flowing to the heating device can be increased by pressurization and the like.
Furthermore, for an embodiment in which only the flow rate through the heating device is acquired, the control method may further include: and if the flow rate of the heating device is more than 0, controlling the soft water of the softening device to flow to the heating device only.
That is, when the heating device has the use requirement, the soft water is controlled to flow to the heating device only, so that the water purifying device is prevented from starting to work in the working process of the heating device, and the normal use of the heating device is affected, for example, the water outlet temperature of the heating device is increased and fluctuated, and even the heating device cannot normally operate.
In the water supply system of the present specification, the water purifying device and the heating device can be directly and/or indirectly connected in communication. Specifically, the water purifying device side can be provided with a communication module, and the heating device side can also be provided with a communication module. When the two devices are in direct communication, at least one of the water purifying device and the heating device can be provided with a controller, and the controller can transmit signals with the device at least provided with the communication module. When the two are in indirect communication, a controller, a master control or a transfer module can be arranged outside the heating device and the water purifying device. The controller can communicate with the communication module of the heating device and the water purifying device, and the starting information of the heating device and the water purifying device can be sent to the controller, so that the controller can timely acquire the use requirements of the heating device and the water purifying device, and the communication state and the flow distribution of each pipeline in the system are combined with flow signals, and the operation states of the heating device and the water purifying device and the like are accurately controlled.
Specifically, the controller may be disposed on the heating device side, and the controller disposed on the heating device side may directly acquire start information of the heating device. The water purifying device can comprise a communication module, and the communication module can carry out information interaction with the controller. The communication module can at least send the starting information of the water purifying device to the controller.
Specifically, when the water supply system includes a water supply device, the heating device and the softening device are located in a housing of the water supply device, the controller may be disposed at the water supply device side, and may directly acquire start information of the heating device. The water purifying device can comprise a communication module, and the communication module can carry out information interaction with the controller. The communication module can at least send the starting information of the water purifying device to the controller.
In some embodiments of the present application, the controller may send various information to the communication module of the water purification device, for example, information indicating that the water heater is heating water, that the water purification device cannot enter water to produce water, information indicating that the water heater is not in use, that the water purification device can produce water normally, information indicating that the water heater is heating water, that the water purification device cannot enter water to produce water but can output water from a tank, and so on. Based on the information which is sent by the controller and reflects the specific states of the current heating device and the water purifying device, the water purifying device knows that water cannot be fed into the water purifying device to prepare water in a corresponding scene, the centrifugal pump of the water purifying device is prevented from idling, parts are damaged, and the service life of the water purifying device is reduced.
Of course, the specific location of the controller is not limited to the above examples, and may be provided alone or on the water purifying device side, etc. Wherein, the heating device and the water purifying device can communicate with the controller through a power line carrier.

In particular, the specific communication principle and working process of the power line carrier communication are not described herein in detail. Of course, the communication modes between the heating device and the water purifying device and the controller are not limited to the above examples, and communication modes such as bluetooth, infrared, wiFi,4G/5G and the like can be used, and the application is not limited thereto.
