The terms "connected" and "connecting" are used broadly, and may be, for example, mechanical or electrical connection, or communication between two elements, or direct or indirect connection through an intermediate medium, and those skilled in the art will understand the specific meaning of the terms as they are used in the specific context. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The utility model discloses provide a fire soft all-in-one, this fire soft all-in-one and integrated water softener and hot water system, can provide the hot soft water after softening and heating, also can provide the cold soft water after softening, under the operating mode that hot soft water and cold soft water go out water simultaneously, can be with hot soft water temperature and flow fluctuation control in less within range. In addition, the zero cold water function can be further expanded on the soft all-in-one machine by reasonably setting the pipeline structure and controlling the on-off.

In the description of the present application, the water heating device is mainly exemplified by a gas water heating device, but it will be understood by those skilled in the art based on the disclosure of the present application that the water heating device is not limited to a gas water heating device, and other forms of instant water heating may also be adopted, and the present application is not further described herein. The gas water heater can be specifically a wall-mounted furnace, a gas water heater and other equipment.

Referring to fig. 1, the soft combustion all-in-one machine 100 may specifically include: the water inlet pipe 1 is used for inputting cold water; the softening mechanism 2 is used for softening the cold water which is input by the water inlet pipe 1 and flows through the softening mechanism 2; the heating mechanism 3 is used for heating the cold water flowing through the heating mechanism 3; a first water outlet pipe 4 connected to an outlet of the heating mechanism 3 and outputting hot water; the second water outlet pipe 5 is connected with the outlet of the softening mechanism 2 and outputs softened cold water; and the flow control device 6 is used for regulating and controlling the flow of cold water output by the second water outlet pipe 5 and the flow of hot water output by the first water outlet pipe 4. It will be understood that the "cold water" described herein is relative to the water at a higher temperature after being heated by the heating means 3, and in practical cases the "cold water" may be tap water supplied by municipalities, that is, normal temperature water.

Generally, the soft-fire all-in-one machine 100 further comprises a housing 110, and the housing 110 is used for accommodating the softening mechanism 2 and the heating mechanism 3. Of course, the softening means 2 and the heating means 3 are mounted in the housing 110, and the flow control device 6 and necessary components such as a connection line and a valve structure are also mounted therein.

The heating mechanism 3 is mainly used for heating cold water flowing through the heating mechanism. Specifically, the form of the cold water that can enter the heating mechanism 3 for heating may be different according to the connection and communication relationship of the specific pipelines inside the soft gas burner 100 and the water demand of the user. For example, the cold water may be cold water softened by the softening mechanism 2; alternatively, the cold water may be tap water that has not been softened by the softening unit 2.

Specifically, the heating mechanism 3 may include a heat exchanger and a burner. The heat exchanger may be a heat exchange tube heat exchanger, but the heat exchanger is not limited to a heat exchange tube heat exchanger, and may also be in the form of an electrical heating heat exchanger. In the embodiments of the present description, the heat exchanger is exemplified by a heat exchange tube type heat exchanger, and other forms of heat exchangers can refer to this form, and detailed descriptions of the heat exchangers are omitted here. When the heating mechanism 3 works, high-temperature flue gas formed by combustion of the burner exchanges heat with a heat exchange tube of the heat exchanger, and water in the heat exchanger is heated.

The outlet of the heating mechanism 3 is connected with a first water outlet pipe 4, one end of the first water outlet pipe 4 is connected with the outlet of the heating mechanism 3, and the other end of the first water outlet pipe 4 is used for outputting hot water to a water consumption point. The hot water may be water softened by the softening means 2 and heated by the heating means 3, or may be water heated only by the heating means 3.

The softening mechanism 2 is mainly used for softening cold water flowing through the interior thereof. The cold water may be part of the normal temperature tap water flowing from the water inlet pipe 1 or the whole normal temperature tap water. Specifically, the softening mechanism 2 includes a resin tank storing a softened resin. In addition, the softening mechanism 2 may further include a salt tank structure or the like in which soft water salt is stored.

The outlet of the softening mechanism 2 is connected with a second water outlet pipe 5, one end of the second water outlet pipe 5 is connected with the outlet of the softening mechanism 2, and the other end (i.e. the output end) is used for outputting softened cold water to a water consumption point. In particular, the output end of the second water outlet pipe 5 can be connected to the equipment needing soft water, including but not limited to washing machines and dishwashers.

For the soft all-in-one machine 100, the water inlet pipe 1 for inputting cold water is the total inlet water of the soft all-in-one machine 100. If the soft all-in-one machine 100 has the working condition that hot water and cold water are used simultaneously, that is, the first water outlet pipe 4 outputs hot water and the second water outlet pipe 5 outputs cold water, under the condition that the total inflow water flow is not changed, the water flow fluctuation entering the heating mechanism 3 is obvious due to the shunting influence of the second water outlet pipe 5, and therefore the hot water temperature fluctuation output from the first water outlet pipe 4 is obvious.

Referring to fig. 2, for a soft and combustible all-in-one machine 100 (a hot water device and a water softener are simply integrated), in a process that the first water outlet pipe 4 outputs hot water to a water using point (taking a shower as an example), the second water outlet pipe 5 outputs cold water to a machine (taking a washing machine as an example) which needs to use cold and soft water. Wherein, curve a shows the variation of the water flow rate of the first water outlet pipe 4, and curve B shows the variation of the water temperature of the first water outlet pipe 4. In a period of time when the washing machine works, when cold (soft) water enters the washing machine from the second water outlet pipe 5, the flow and the water temperature at the shower head can obviously fluctuate, wherein the water temperature fluctuates by about +/-4.5 ℃, the temperature exceeds the temperature sensing range of a user, and the user can obviously sense the cold and hot changes of the water temperature. That is to say, for the soft all-in-one machine 100 that fires that carries out simple integration with hot water system and water softener, when first outlet pipe 4 and second outlet pipe 5 go out water simultaneously, the temperature fluctuation that first outlet pipe 4 supplied with is great, brings the body sense change of neglecting cold road heat for the user to lead to the user to use and experience relatively poor.

The soft all-in-one gas burner 100 provided by the application is further provided with a flow control device 6, and the flow control device 6 is used for regulating and controlling the flow of cold water output by the second water outlet pipe 5 and the flow of hot water output by the first water outlet pipe 4. Utilize this flow control device 6 can adjust the rivers proportion that flows to heating mechanism 3 and second outlet pipe 5, under the unchangeable condition of total inflow, control second outlet pipe 5's flow, when the preferential guarantee user is to hydrothermal user demand, can be with the hot water temperature control of first outlet pipe 4 output in less fluctuation range, the user is difficult for perceiving the change of temperature in the body sense to guarantee that the user has good use and experiences.

In one or more embodiments, the flow control device 6 may regulate the flow of cold water output by the second water outlet pipe 5 and the flow of hot water output by the first water outlet pipe 4, including the following situations: the flow control device 6 can make the water volume output by any one of the second water outlet pipe 5 and the first water outlet pipe 1 be 0, that is, the water volume output by the other one of the second water outlet pipe 5 and the first water outlet pipe 1 is the maximum.

Referring to fig. 3, the soft all-in-one burner 100 provided by the present invention is taken as an example, wherein, in the process of outputting hot water to a water point (taking a shower as an example) by the first water outlet pipe 4, cold water is outputted to a machine (taking a washing machine as an example) which needs to use cold and soft water by the second water outlet pipe 5. Wherein, curve C shows the variation of the water flow rate of the first water outlet pipe 4, and curve D shows the variation of the water temperature of the first water outlet pipe 4. During a period of time when the washing machine works, when cold (soft) water enters the washing machine, the flow control device 6 limits the flow flowing to the second water outlet pipe 5, so that the flow and water temperature fluctuation at the shower head are obviously controlled, for example, the water temperature fluctuation is about +/-2 ℃, and the use experience of a user is better ensured; meanwhile, the cold water outlet flow of the second water outlet pipe 5 can ensure the normal use of the machine (such as a washing machine) which needs to use cold and soft water.

The specific structural components and the operation principle of the soft gas burner 100 will be described in detail below with reference to the specific embodiments and the accompanying drawings.

In one embodiment, the soft-fire all-in-one machine 100 may further include a first flow detection mechanism 91, a second flow detection mechanism 92, and a controller; the first flow detection mechanism 91 is used for detecting the flow at the water inlet pipe 1; the second flow rate detection mechanism 92 is used for detecting the flow rate of water flowing through the heating mechanism 3; the controller is electrically connected to the first flow rate detecting mechanism 91, the second flow rate detecting mechanism 92 and the flow rate control device 6, and is configured to regulate and control the flow rate control device 6 according to the flow rate detected by the first flow rate detecting mechanism 91 and the flow rate detected by the second flow rate detecting mechanism 92.

In the present embodiment, the gas soft all-in-one machine 100 further includes a first flow rate detection mechanism 91, a second flow rate detection mechanism 92, and a controller. Wherein, this controller can detect mechanism 91 and second flow according to first flow and detect mechanism 92 and acquire total influent stream and shunt to the first water flow of heating mechanism 3 respectively, and further, can confirm the second water flow of shunting to second outlet pipe 5 based on influent stream and first water flow to regulate and control flow control device 6 and carry out reasonable reposition of redundant personnel based on the flow condition.

It should be noted that: in the embodiments of the present disclosure, the specific number and position of the flow rate detection mechanisms are merely a typical example, and those skilled in the art can adaptively adjust the flow rate detection mechanisms according to actual pipeline conditions and the like. For example, flow detection mechanisms may be respectively disposed at the water inlet pipe 1 and the second water outlet pipe 5, so as to respectively obtain a total water inflow and a second water flow shunted to the second water outlet pipe 5, and a first water flow shunted to the heating mechanism 3 may be determined based on the water inflow and the second water flow; alternatively, flow rate detecting means or the like for detecting the flow rate of water flowing through the heating means 3 and acquiring the flow rate of water flowing through the second water outlet pipe 5 may be provided separately. It can be understood that a reasonable number of flow detection mechanisms can be arranged at other reasonable positions to obtain the total water inlet flow, the first water flow shunted to the heating mechanism 3 and the second water flow shunted to the second water outlet pipe 5; here, the description of other cases is not repeated one by one.

Referring to fig. 1, 4, 5 or 6, in one embodiment, a first connection pipeline 71 is disposed between the outlet of the softening mechanism 2 and the inlet of the heating mechanism 3, one end of the second water outlet pipe 5 is connected to the first connection pipeline 71, and the other end outputs softened cold water.

In the present embodiment, a first connection pipe 71 may be disposed between the outlet of the softening mechanism 2 and the inlet of the heating mechanism 3, the softened water in the softening mechanism 2 may be supplied to the heating mechanism 3 through the first connection pipe 71, and the soft water heated by the heating mechanism 3 may be supplied to the user. The inlet end of the second outlet pipe 5 may be connected in the first connecting line 71 in the water flow direction, and the other end serves as an output end for outputting softened cold water. The junction of the inlet end of the second water outlet pipe 5 and the first connecting line 71 may serve as a diversion point for the cold and soft water. When cold soft water and hot soft water are used simultaneously, after the water softened by the softening mechanism 2 flows to the diversion point through the first connecting pipe 71, a part of the water enters the heating mechanism 3 through the first connecting pipe 71 to be heated, and the other part of the water enters the second water outlet pipe 5.

Wherein the flow control means 6 may be located in said second outlet pipe 5. When the flow control means 6 is arranged in the second outlet pipe 5, it is possible to directly regulate the flow of cold soft water, which corresponds to regulating the flow to the heating means 3 also in the case of a constant total inlet flow.

The flow rate control device 6 may be located at the branching point. When the flow control device 6 is disposed at the diversion point, the flow rate of the cold soft water and the flow rate to the heating mechanism 3 can be directly adjusted. Of course, the flow control device 6 may also be disposed at other positions, as long as the flow control device 6 can regulate and control the cold water flow output by the second water outlet pipe 5 and the flow supplied to the heating mechanism 3 (i.e. the hot water flow output by the first water outlet pipe 4 under the condition that the parameters of the heating mechanism 3 are not changed).

It should be noted that: the first connecting pipeline 71, the second water outlet pipe 5 and the like mentioned in the present specification may be in the form of a hollow pipeline, or may be in the form of an integrated module formed by cooperating with the flow control device 6, and in particular, the present application is not limited herein.

In this specification, the flow control device 6 may have different states according to different use conditions of cold and hot water. Specifically, the flow control device 6 at least has a first state and a second state, and the flow rate passing through the second water outlet pipe 5 in the first state is greater than the flow rate passing through the second water outlet pipe 5 in the second state.

In the first state, it indicates that the user does not have a demand for hot water, and at this time, it is not necessary to limit the flow of cold water in the second outlet pipe 5; in the second state, the requirement of the user for hot water is indicated, and when the requirement of the user for hot water is available, the flow control device 6 can limit the flow of the cold water flowing into the second water outlet pipe 5, and preferentially ensure the flow of the hot water at the first water outlet pipe 4.

Depending on the specific form of the flow control device 6, the different states of the flow control device 6 and the specific form assumed in the different states may also differ. For example, the flow control device 6 may include any one of the following: a flow regulating electromagnetic valve and a flow regulating valve with stepless and adjustable opening degree.

Taking the flow regulating solenoid valve as an example, it may comprise a first state in which it is de-energized and a second state in which it is energized. When the flow rate regulating solenoid valve is not electrified, the flow cross section of the flow rate regulating solenoid valve is in the maximum state, and the flow cross section is S1; when the flow rate regulating solenoid valve is electrified, the flow rate cross section is in a minimum state, the flow cross section is S2, and S1 is more than S2.

When a user only uses cold soft water, the flow regulating electromagnetic valve is not electrified (namely in a first state), and the flow of the cold water of the second water outlet pipe 5 is not limited; at this time, if the water consumption point at the hot soft water is turned on, after the flow in the first connection pipeline 71 reaches the start flow of the heating mechanism 3, the flow regulating solenoid valve is energized (i.e., in the second state), and the heating mechanism 3 is normally started, so as to ensure a large flow of water for the hot soft water.

When the user only uses the hot soft water, the cold soft water port of the second water outlet pipe 5 does not discharge water; if the cold soft water is turned on, a signal indicating that the flow rate supplied to the heating mechanism 3 is decreased is detected, and at this time, the flow rate adjustment solenoid valve is energized to restrict the cold soft water to a low flow rate state (i.e., to switch from the first state to the second state), thereby controlling the temperature fluctuation of the hot soft water.

In the following embodiments, the flow rate control device 6 will be described by way of example mainly of a flow rate control valve (for example, a PSG valve) whose opening degree is steplessly adjustable.

Referring to fig. 6, an external pipeline is further connected between the first water outlet pipe 4 and the water inlet pipe 1, and the external pipeline is matched with a water path inside the soft combustion all-in-one machine 100 to form a circulation loop, so that the soft combustion all-in-one machine 100 can preheat and circulate water in the pipeline, that is, the soft combustion all-in-one machine 100 has a zero cold water function, a user can obtain water with a proper temperature at a water consumption point in the first time, and the use experience of the user is further improved.

For a user who installs the water return pipe 101, the external pipeline may include the water return pipe 101, which may be connected to the water inlet pipe 1 and the first water outlet pipe 4 by using the water return pipe 101, thereby forming a circulation loop.

For users who do not install the water return pipe 101, the external pipeline may include a cold water pipe connected to the water consumption point from the water inlet, that is, the cold water pipe serves as the water return pipe and is also communicated with the water consumption points, and when cold water is used at the water consumption points, the cold water pipe conveys tap water to the water consumption points for the users to use.

In order to enable the above-mentioned embodiment without the water return pipe 101 to realize a preheating cycle without any conflict with normal water usage, a constant pressure water return valve 102 may be additionally installed in the external pipeline, specifically, at the farthest end water usage point. For example, the farthest water using point is a position of a basin in a toilet, and the hot water pipe 103 and the cold water pipe which are communicated with the first water outlet pipe 4 are connected by the constant pressure water return valve 102 to form a preheating circulation loop. Specifically, the constant pressure water return valve 102 is connected in parallel with the water consumption point. The constant pressure water return valve 102 is opened during the preheating cycle, and the first water outlet pipe 4 (or the hot water pipe 103 connected with the first water outlet pipe 4) is communicated with the cold water pipe. When water is normally used, the constant pressure water return valve 102 is in a disconnected state, and the first water outlet pipe 4 is not communicated with the cold water pipe.

Referring to fig. 4 or 5, the water inlet pipe 1 is provided with a water inlet, and a second connecting pipeline 72 is connected between the water inlet and the inlet of the heating mechanism 3. The second connecting line 72 can serve as a bypass line for the first connecting line 71. As shown in fig. 4, the connection position of the second connection pipeline 72 and the first connection pipeline 71 can be located downstream of the junction point of the second water outlet pipe 5 and the first connection pipeline 71; as shown in fig. 5, the connection position of the second connection pipe 72 and the first connection pipe 71 may be located upstream of the junction point of the second water outlet pipe 5 and the first connection pipe 71.

As shown in fig. 4 or 5, a first valve structure 81 may be provided in the second connecting line 72. The first valve structure 81 is used to open and close the second connecting line 72. Specifically, the first valve structure 81 may be a solenoid valve having a function of controlling the on/off of the water path.

As shown in fig. 4, a second valve structure 82 is disposed on the first connecting pipeline 71 between the second water outlet pipe 5 and the heating mechanism 3. In particular, the second valve structure 82 may be in the form of a one-way valve. The second valve structure 82 may be in the form of a solenoid valve having a function of controlling the on/off of the water path. When the second valve structure 82 is a one-way valve, it is used to ensure one-way conduction of fluid from the softening means 2 to the heating means 3, thereby preventing water in the heating means 3 from flowing back into the softening means 2.

Referring to fig. 4 and 6 in combination, the soft start engine 100 has a preheating cycle state and a non-circulation state. In the preheat cycle state, the first valve structure 81 is open and the second valve structure 82 is closed. In the non-circulating state, the second valve structure 82 is open and the first valve structure 81 is closed. Wherein, under the preheating circulation state, inlet tube 1, second connecting line 72, first outlet pipe 4 and can form the circulation circuit between the external pipeline, still be provided with circulating pump 9 in the circulation circuit.

When the hot water outlet end of the water point is in the closed state, it indicates that the user does not use the hot water, and at this time, the soft combustion all-in-one machine 100 can start the preheating function in the modes of automatic switching or manual operation of the display preheating function key, and the soft combustion all-in-one machine enters the preheating circulation state. When the hot water outlet end of the water consumption point is opened, which indicates that the user has a demand for using hot water, the soft fire all-in-one machine 100 can be automatically switched from the preheating circulation state to the non-circulation state.

When the soft start engine 100 is in the non-circulating state, the second valve structure 82 is opened, the first valve structure 81 is closed, which is equivalent to the second connecting pipeline 72 as a bypass pipeline being in the disconnected state, and this is similar to the working state of the soft start engine 100 shown in fig. 1. The soft and cold water can be supplied to the user by using the soft and light all-in-one machine 100, and the hot and soft water can also be supplied to the user. When cold soft water is used while hot soft water is used, the flow control device 6 is used for throttling the cold soft water, the flow of hot water is preferentially ensured, and the fluctuation of the water temperature of the hot water is controlled.

Among them, it should be noted that: the meaning of "on" of the second valve structure 82 is different when the second valve structure 82 is in a different form. Here, the conduction of the second valve structure 82 mainly means that the water flow in the first connection pipe 71 can flow from the softening means 2 to the heating means 3. When the second valve structure 82 is an electromagnetic valve, the second valve structure 82 is conducted, i.e. the second valve structure 82 is in an open state; when the second valve structure 82 is a one-way valve, the second valve structure 82 is in communication, i.e. the fluid is in one-way communication from the softening means 2 to the heating means 3.

When the soft all-in-one machine 100 is in the preheating circulation state, the first valve structure 81 is in the conducting state, the second valve structure 82 is in the closing state, the second connecting pipeline 72 as the bypass pipeline is in the opening state, and because the pipe resistance of the second connecting pipeline 72 is smaller than the pipe resistance from the water inlet to the inlet of the softening mechanism 2, during circulation, tap water entering from the water inlet preferentially enters the heating mechanism 3 through the second connecting pipeline 72, namely, in the preheating circulation state, the circulating water is tap water entering from the water inlet. In addition, when the soft gas burner 100 is in the preheating cycle state, the second water outlet pipe 5 is opened, and cold soft water can be supplied to a user. After the water outlet pipe 5 is opened, cold water injected from the water inlet pipe 1 is divided, one path of cold water enters the softening mechanism 2 and is output from the water outlet pipe 5, the other path of cold water is injected into the heating mechanism 3 from the second connecting pipeline 72, and at the moment, the water pressures on the two sides of the second valve structure 82 are basically consistent.

As shown in fig. 6, when the soft start engine 100 is in the preheating cycle state, the inside of the soft start engine 100 may form a circulation loop. Specifically, the circulation loop formed may include: the water inlet pipe 1, the second connecting pipeline 72, part of the first connecting pipeline 71, the first water outlet pipe 4 and an external pipeline. Wherein a circulation pump 9 may be arranged in the circulation circuit. The circulating pump 9 can pressurize the fluid in the circulating loop to provide circulating flow power. Specifically, the location of the circulation pump 9 may be located in the housing 110 of the soft all-in-one machine 100, near the water inlet pipe 1 at the bottom of the housing 110.

The running water entering from the water inlet pipe 1 is used as a starting point, the water to be preheated firstly flows through the circulating pump 9, then enters the second connecting pipeline 72 and part of the first connecting pipeline, then enters the heating mechanism 3 for heating, then flows out from the first water outlet pipe 4, and returns to the water inlet pipe 1 after flowing to the external pipeline, so that a cycle is completed. The water returning to the water inlet pipe 1 is circulated again until the temperature in the external pipeline reaches the set temperature.

When the soft-fire integrated machine 100 is in the non-circulation state, for a scene where an external pipeline is arranged, the external pipeline is in the disconnection state, for example, the constant pressure water return valve 102 is in the disconnection state.

In addition, as shown in fig. 4, the circulation pump 9 may be started when the soft-start integrated machine 100 is in the non-circulation mode; or as shown in fig. 1, in the case that the soft combustion all-in-one machine 100 is not provided with an external pipeline, the soft combustion all-in-one machine 100 may be provided with a circulating pump 9. When the user water demand is great, for example hot water system and the electrical apparatus simultaneous working that needs to use cold soft water, when first outlet pipe 4 and second outlet pipe 5 go out water simultaneously, can open this circulating pump 9 and carry out the pressure boost to flow to the hot water end compensates, prevents that hot water end flow from reducing and leading to the temperature undulant, perhaps hot water end flow undersize, leads to heating mechanism 3 to flame out.

As shown in fig. 4 or 6, a third valve structure 83 may also be provided on the inlet conduit 1. The third valve structure 83 may be embodied in the form of a solenoid valve having a function of controlling the make and break of the water path. The third valve structure 83 may be in a normally open state when the soft water is in use or may be used (e.g., the resin is in a non-regeneration process), and the third valve structure 83 may be in a closed state when the resin is in a regeneration process.

As shown in fig. 5, a third valve structure 83 may also be provided on the inlet conduit 1. The third valve structure 83 may be in the form of a solenoid valve having a function of controlling the on/off of the water path. When the limp-fire all-in-one machine 100 is in the circulation mode, the third valve structure 83 may be in a closed state and the first valve structure 81 in a conductive state; when the limp-fire 100 is in the non-circulating mode, the third valve structure 83 may be in a conducting state and the first valve structure 81 may be in a closed state.

In one embodiment, for the soft drink dispenser 100 with zero cold water function, in the non-circulating state, the flow control device 6 may be in the first state or the second state; in the preheating cycle state, the flow control device 6 may be in the second state or a third state, where the flow rate through the second water outlet pipe 5 in the third state is smaller than the flow rate through the second water outlet pipe 5 in the second state.

Referring to fig. 4 and fig. 6, when the soft-fire all-in-one machine 100 is in the non-circulation state, the flow control device 6 can be in the first state or the second state. Due to the different specific forms of the flow control means 6, the specific presentation of the first and second states is different. In this embodiment, the flow rate control device 6 will be described by taking a flow rate control valve (for example, PSG) whose opening degree is steplessly adjustable as an example.

Referring to fig. 7, when the soft-start engine 100 is in a non-circulating state, the flow control device 6 can be in different states according to different water usage conditions. For example, when the water flow rate is obtained: when the current user uses the cold and soft water alone, the flow control device 6 is in the first state, and the PSG valve is in the fully open state (namely 0 °); when the water flow rate obtained represents: when only hot soft water is used, the flow control device 6 is controlled to be in the second state, for example, the PSG valve can be in the first angle θ 1, so that when cold soft water is used subsequently, flow limitation is performed in time, and the large fluctuation of the outlet water temperature of the first water outlet pipe 4 is prevented; when the water flow rate obtained represents: when the cold soft water and the hot soft water are used simultaneously, the flow control device 6 is controlled to be in the second state, specifically, the PSG valve can be in the first angle θ 1, and the outlet water temperature of the first outlet pipe 4 is prevented from being greatly fluctuated. The value of the first angle θ 1 is not specifically limited in this application, and for example, the first angle θ 1 may be 65 °.

When the cold and hot soft water are used simultaneously, the PSG valve may have a first angle θ 1 (e.g., 65 °) as an initial restriction angle, and during subsequent use, the angle of the PSG valve may be adaptively adjusted according to a user water usage situation. For example, the opening of the subsequent PSG valve may be automatically adjusted according to the flow rate of the hot and cold water ends to maintain the flow rate of the hot and cold water ends at a preset ratio, and the flow rate of the hot water end is greater than that of the cold water end as a whole, and the data of the preset ratio is not specifically limited in this application, for example, the flow rate ratio of the hot water end to the cold water end may be 3: 1.

When the soft combustion and heating integrated machine 100 is in the preheating circulation state, the flow control device 6 may be in the second state or a third state, and the flow passing through the second water outlet pipe 5 in the third state is smaller than the flow passing through the second water outlet pipe 5 in the second state. Specifically, the flow control device 6 may be in different states depending on the water usage.

For example, when the soft start engine 100 is in the preheating cycle state and the cold soft water is in the non-use state, the flow control device 6 may be in the second state. For example, the PSG valve may be at the first angle θ 1, so that when cold or hot soft water is used later, the flow limitation is performed in time, and the large fluctuation of the outlet water temperature of the first water outlet pipe 4 is prevented.

When the soft start integrated machine 100 is in the preheating circulation state, the flow control device 6 may be first controlled to the third state before the circulation pump 9 is started if it is recognized that the user is using the cold soft water according to the first and second flow

rate detection mechanisms

91 and 92. In particular, the PSG valve may be at the second angle θ 3 and then the circulation pump 9 is re-activated, ensuring proper operation of the circulation. Particularly, in the case of a circulation circuit provided with the constant pressure water return valve 102, when the user uses cold soft water, a certain pressure relief effect is generated in the circulation circuit, and at this time, in order to ensure that the pressure in the circulation circuit can sufficiently open the constant pressure water return valve 102, the PSG valve may be used to further limit the flow, that is, to reduce the opening of the PSG valve. Wherein the second angle θ 3 is greater than the first angle θ 1, and accordingly, the opening degree of the PSG valve at the first angle is greater than that at the second angle. Of course, the value of the second angle θ 3 is not specifically limited in this application, and the second angle θ 3 may be 80 °. Subsequently, when the flow detection mechanism recognizes that the hot water flow reaches the first preset flow, the opening of the flow control device 6 may be adjusted until the cold soft water flow is maintained at the second preset flow. Thereby ensuring that the flow of the hot water and the flow of the cold and soft water can better meet the use requirements of users. The specific values of the first preset flow rate and the second preset flow rate are not specifically limited in this application, as long as the use requirements of the user are better met.
