Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water heating softening, in particular to a soft water and hot water integrated machine and a control method thereof. BACKGROUND

[0002] At present, with the improvement of people's living standards, people's requirements for daily water are also more and more strict. Due to the influence of factors such as region, the water quality in different places is uneven, and the difference of water quality resources is relatively large. The water quality in most areas is hard. Long-term use of water with high hardness will make people's skin dry, rough and age quickly. Therefore, people's demand for soft water is increasing. Soft water contains little or no soluble calcium and magnesium compounds. Using soft water can effectively inhibit fungi, delay skin aging and prevent water from scaling after heating.

[0003] Most of the soft water machines and hot water devices on the market are independent products, which need to be installed independently during installation. Not only does it occupy a large space, but also the purchase cost is high, and it is difficult to use and install. In order to solve the above problems, the present application provides a soft water and hot water integrated machine which can not only solve the problem of hot water demand, but also reduce the hardness of water. The soft water and hot water integrated machine integrates the hot water device and the soft water machine. The soft water and hot water integrated machine can be connected to different water points, such as a bathroom, to provide hot soft water for users to take a bath; for example, a kitchen, to provide cold soft water for appliances such as dishwashers; for example, a balcony, to provide cold soft water for appliances such as washing machines.

[0004] However, the present application found that: when the soft water device needs to use cold soft water at the same time as the hot soft water is output, the temperature of the hot soft water fluctuates greatly due to the influence of the diversion of these appliances, usually about ± 4℃, which leads to poor user experience of hot soft water.

[0074] In order to make the technical solutions in the present application better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts should fall within the scope of the present application.

[0075] It should be noted that when an element is referred to as being "provided on" another element, it can be directly on the other element or there can be an intervening element. The terms "connected," "coupled," and the like, should be interpreted broadly, in a manner similar to the term "connected." For example, they can be mechanical connections, electrical connections, or connections in terms of other transmission media - including wireless transmission media - that enable two elements to communicate in terms of the functionality described herein. The terms "vertical," "horizontal," "left," "right," and similar terms are used for explanation purposes only and are not intended to be limiting.

[0076] Unless otherwise defined, 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 application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting. As used in this description, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0077] The fuel-softening integrated machine integrates a softening device and a hot water device, and can provide softened and heated hot soft water and softened cold soft water. In the working condition of simultaneous water output of the hot soft water and the cold soft water, the temperature and flow fluctuation of the hot soft water can be controlled in a small range. In addition, the zero cold water function can be further expanded on the fuel-softening integrated machine by reasonable setting and on-off control of the pipeline structure.

[0078] In the specification of the present application, the hot water device is mainly exemplified by a gas hot water device, but those skilled in the art can know from the disclosure of the present application that the hot water device is not limited to the gas hot water device, and other forms of instant heating of water can also be adopted, which will not be described one by one in the present application. The gas hot water device can be a wall-mounted stove, a gas water heater, or the like.

[0079] Please refer to Figure 1The water softening and heating integrated machine 100 can specifically include: a water inlet pipe 1 for inputting cold water; a softening mechanism 2 for softening the cold water input by the water inlet pipe 1 and flowing through the softening mechanism 2; a heating mechanism 3 for heating the cold water flowing through the heating mechanism 3; a first water outlet pipe 4 connected with the outlet of the heating mechanism 3 and outputting hot water; a second water outlet pipe 5 connected with the outlet of the softening mechanism 2 and outputting softened cold water; and a flow control device 6 for regulating the flow of the cold water output by the second water outlet pipe 5 and the flow of the hot water output by the first water outlet pipe 4. It can be understood that the "cold water" described herein is relative to the water of a higher temperature after being heated by the heating mechanism 3, and in actual cases, the "cold water" can be tap water provided by a municipal government, i.e., normal temperature water.

[0080] Generally, the water softening and heating integrated machine 100 further includes a housing 110 for accommodating the softening mechanism 2 and the heating mechanism 3. Of course, in addition to the softening mechanism 2 and the heating mechanism 3, the housing 110 also has the flow control device 6 and necessary connecting pipes and valve structures and other components installed therein.

[0081] The heating mechanism 3 is mainly used for heating the cold water flowing through the inside thereof. Specifically, the form of the cold water that can enter the heating mechanism 3 for heating can be different according to the connection and communication relationship of the specific pipes inside the water softening and heating integrated machine 100 and the water demand of a user and the like. For example, the cold water can be the cold water that has been softened by the softening mechanism 2, or the cold water can also be tap water that has not been softened by the softening mechanism 2.

[0082] Specifically, the heating mechanism 3 can include a heat exchanger and a burner. The heat exchanger can specifically be a heat exchange pipe type heat exchanger, and of course, the heat exchanger is not limited to the heat exchange pipe type heat exchanger, and it can also be an electric heating type heat exchanger and the like. In the embodiments of the present application, the heat exchanger is taken as an example of the heat exchange pipe type heat exchanger, and other forms of heat exchangers can be referred to this form, and the present application will not be expanded and described here. When the heating mechanism 3 works, the high-temperature flue gas formed by the combustion of the burner is used to exchange heat with the heat exchange pipes of the heat exchanger, so as to heat the water inside the heat exchanger.

[0083] The outlet of the heating mechanism 3 is connected with the 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 is used for outputting hot water to a water use point. The hot water can be the water that has been softened by the softening mechanism 2 and heated by the heating mechanism 3, or can also be the water that has only been heated by the heating mechanism 3.

[0084] The softening mechanism 2 is mainly used for softening the cold water flowing through the inside thereof. The cold water can be part of the normal temperature tap water flowing from the water inlet pipe 1, or all of the normal temperature tap water. Specifically, the softening mechanism 2 includes a resin tank storing softening resin. In addition, the softening mechanism 2 can also include a salt tank structure storing salt, etc.

[0085] 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 the softened cold water to the water using point. Specifically, the output end of the second water outlet pipe 5 can be connected with the equipment needing soft water, including but not limited to washing machine, dishwasher, etc.

[0086] For the soft water integrated machine 100, the water inlet pipe 1 for inputting cold water is the total water inlet of the soft water integrated machine 100. If the soft water integrated machine 100 appears the working condition of using hot water and cold water at the same time, i.e. the first water outlet pipe 4 outputs hot water while the second water outlet pipe 5 outputs cold water, under the condition that the total water inlet flow does not change, due to the shunting effect of the second water outlet pipe 5, the water flow entering the heating mechanism 3 will fluctuate obviously, thereby making the water temperature of the hot water output from the first water outlet pipe 4 fluctuate obviously.

[0087] Please refer to Figure 2 For a soft water integrated machine 100 (simply integrating the hot water device and the water softener), in the process of outputting hot water from the first water outlet pipe 4 to the water using point (taking the shower as an example), the second water outlet pipe 5 outputs cold water to the machine (taking the washing machine as an example) needing to use cold soft water. Among them, curve A shows the change of the water flow of the first water outlet pipe 4, and curve B shows the change of the water temperature of the first water outlet pipe 4. During the working time of the washing machine, when the second water outlet pipe 5 inputs cold (soft) water to the washing machine, the flow and water temperature at the shower will fluctuate obviously, among which the water temperature fluctuation is about ±4.5℃, which exceeds the user's temperature range, and the user can obviously perceive the change of the cold and hot water temperature. That is to say, for the soft water integrated machine 100 simply integrating the hot water device and the water softener, when the first water outlet pipe 4 and the second water outlet pipe 5 output water at the same time, the water temperature supplied by the first water outlet pipe 4 fluctuates greatly, which brings the user the change of the cold and hot feeling, thereby leading to poor user experience.

[0088] The fuel soft all-in-one machine 100 provided in the present application further comprises a flow control device 6, which is used to regulate the cold water flow output by the second water outlet pipe 5 and the hot water flow output by the first water outlet pipe 4. The flow control device 6 can be used to adjust the water flow ratio to the heating mechanism 3 and the second water outlet pipe 5, and control the flow of the second water outlet pipe 5 under the condition that the total water inflow is unchanged. When the use demand of hot water by the user is preferentially guaranteed, the water temperature output by the first water outlet pipe 4 can be controlled within a small fluctuation range, and the user cannot easily perceive the change of water temperature in the sense of body, thereby guaranteeing a good use experience of the user.

[0089] In one or more embodiments, the flow control device 6 regulating the cold water flow output by the second water outlet pipe 5 and the hot water flow output by the first water outlet pipe 4 can include the following cases: the flow control device 6 can make the water output by any one of the second water outlet pipe 5 and the first water outlet pipe 4 to be 0, and the water output by the other one of the second water outlet pipe 5 and the first water outlet pipe 4 to be the maximum.

[0090] Please refer to Figure 3 For example, the fuel soft all-in-one machine 100 provided in the present application, and the same is used in the process that the first water outlet pipe 4 outputs hot water to the water use point (for example, a shower head), and the second water outlet pipe 5 outputs cold water to the machine (for example, a washing machine) requiring to use cold soft water. The curve C shows the change of the water flow of the first water outlet pipe 4, and the curve D shows the change of the water temperature of the first water outlet pipe 4. During a period of time when the washing machine works, when the washing machine inflows cold (soft) water, the flow control device 6 limits the flow to the second water outlet pipe 5, so that the flow and water temperature fluctuation at the shower head is obviously controlled, for example, the water temperature fluctuation is about ±2℃, which preferably guarantees the use experience of the user; at the same time, the cold water flow output by the second water outlet pipe 5 can guarantee the normal use of the machine (for example, the washing machine) requiring to use cold soft water.

[0091] The specific structure, composition and working principle of the fuel soft all-in-one machine 100 will be described in detail below in combination with specific embodiments and the drawings.

[0092] In one embodiment, the fuel soft all-in-one machine 100 can further comprise a first flow detection mechanism 91, a second flow detection mechanism 92 and a controller; the first flow detection mechanism 91 is used to detect the flow at the water inlet pipe 1; the second flow detection mechanism 92 is used to detect the water flow flowing through the heating mechanism 3; the controller is electrically connected with the first flow detection mechanism 91, the second flow detection mechanism 92 and the flow control device 6 respectively, and is used to regulate the flow control device 6 according to the flow detected by the first flow detection mechanism 91 and the flow detected by the second flow detection mechanism 92.

[0093] In the embodiment, the softening and heating all-in-one machine 100 further comprises a first flow detection mechanism 91, a second flow detection mechanism 92 and a controller. The controller can acquire the total water inflow and the first water inflow to the heating mechanism 3 according to the first flow detection mechanism 91 and the second flow detection mechanism 92 respectively. Further, the second water inflow to the second water outlet pipe 5 can be determined based on the total water inflow and the first water inflow, so that the flow control device 6 can be reasonably controlled based on the flow condition.

[0094] It should be noted that the specific number and position of the flow detection mechanism in the embodiments of the present application are only a typical example, and those skilled in the art can adaptively adjust them according to the actual pipeline condition. For example, flow detection mechanisms can be respectively arranged at the water inlet pipe 1 and the second water outlet pipe 5 to respectively acquire the total water inflow and the second water inflow to the second water outlet pipe 5, and the first water inflow to the heating mechanism 3 can be determined based on the total water inflow and the second water inflow. Alternatively, flow detection mechanisms for detecting the water inflow to the heating mechanism 3 and acquiring the water inflow of the second water outlet pipe 5 can be respectively arranged. It can be understood that the total water inflow, the first water inflow to the heating mechanism 3 and the second water inflow to the second water outlet pipe 5 can also be obtained by arranging a reasonable number of flow detection mechanisms at other reasonable positions. Here, other conditions will not be described one by one.

[0095] Please refer to any of the drawings, Figure 1 , Figure 4 , Figure 5 or Figure 6 In one embodiment, a first connecting pipeline 71 is arranged 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 connecting pipeline 71, and the other end outputs softened cold water.

[0096] In the embodiment, a first connecting pipeline 71 can be arranged between the outlet of the softening mechanism 2 and the inlet of the heating mechanism 3, and the softened water in the softening mechanism 2 can be supplied to the heating mechanism 3 through the first connecting pipeline 71, and the softened water heated by the heating mechanism 3 can be supplied to the user. In the water flow direction, the inlet end of the second water outlet pipe 5 can be connected to the first connecting pipeline 71, and the other end serves as an output end for outputting softened cold water. The intersection point of the inlet end of the second water outlet pipe 5 and the first connecting pipeline 71 can serve as a soft water distribution point. When cold soft water and hot soft water are used at the same time, the water softened by the softening mechanism 2 flows to the distribution point through the first connecting pipeline 71, and part of the water enters the heating mechanism 3 through the first connecting pipeline 71 for heating, and the other part enters the second water outlet pipe 5.

[0097] The flow control device 6 can be located in the second water outlet pipe 5. When the flow control device 6 is arranged in the second water outlet pipe 5, it can directly regulate the flow of cold soft water, and when the total water inlet flow is unchanged, it is equivalent to regulating the flow to the heating mechanism 3.

[0098] In addition, the flow control device 6 can also be located at the above-mentioned shunt point. When the flow control device 6 is arranged at the shunt point, it can directly regulate the flow of cold soft water and the flow to the heating mechanism 3. Of course, the flow control device 6 can also be arranged at other positions, as long as the flow control device 6 can regulate the flow of cold water output by the second water outlet pipe 5 and the flow to the heating mechanism 3 (i.e. the flow of hot water output by the first water outlet pipe 4 when the parameters of the heating mechanism 3 itself are unchanged).

[0099] It should be noted that the first connecting pipe 71, the second water outlet pipe 5, etc. mentioned in the present application can be in the form of a hollow pipe, or can be in the form of an integrated module cooperating with the flow control device 6. Specifically, the present application does not limit it here.

[0100] In the present specification, the flow control device 6 can have different states according to different cold and hot water use conditions. Specifically, the flow control device 6 has at least a first state and a second state, and the flow through the second water outlet pipe 5 in the first state is greater than the flow through the second water outlet pipe 5 in the second state.

[0101] In the first state, it indicates that the user has no demand for hot water, at this time, there is no need to limit the flow of cold water into the second water outlet pipe 5; in the second state, it indicates that the user has a demand for hot water, when the user has a demand for hot water, the flow control device 6 can limit the flow of cold water into the second water outlet pipe 5, and preferentially ensure the flow of hot water at the first water outlet pipe 4.

[0102] According to the specific form of the flow control device 6, the different states of the flow control device 6 and the specific form presented in different states are also different. For example, the flow control device 6 can include any one of the following: a flow regulating solenoid valve, an open degree stepless adjustable flow regulating valve.

[0103] Taking the flow regulating solenoid valve as an example, it can include a first state of no power and a second state of power. When the flow regulating solenoid valve is not powered, its flow cross section is in a maximum state, and the flow cross section is S1; when the flow regulating solenoid valve is powered, its flow cross section is in a minimum state, and the flow cross section is S2, S1>S2.

[0104] When the user only uses cold soft water, the flow regulating solenoid valve is not powered (i.e. in the first state), and does not limit the flow of cold water from the second water outlet pipe 5; at this time, if the hot soft water point is opened, the flow in the first connecting pipe 71 reaches the starting flow of the heating mechanism 3, the flow regulating solenoid valve is powered (i.e. in the second state), and the heating mechanism 3 is normally started to ensure large flow of hot soft water.

[0105] When the user only uses hot soft water, the cold soft water outlet of the second water outlet pipe 5 does not supply water; at this time, if the cold soft water is opened, a signal that the flow to the heating mechanism 3 is small can be detected, at this time, the flow regulating solenoid valve is powered, and the cold soft water is limited to a small flow state (i.e. switched from the first state to the second state), thereby controlling the temperature fluctuation of the hot soft water.

[0106] In the following embodiments, the flow control device 6 is mainly illustrated by taking a flow regulating valve (such as a PSG valve) with stepless adjustable opening degree as an example.

[0107] Please refer to Figure 6 The first water outlet pipe 4 and the water inlet pipe 1 are further connected with an external connecting pipe, and the external connecting pipe and the water circuit inside the soft fuel integrated machine 100 form a circulation loop, so that the soft fuel integrated machine 100 can preheat and circulate the water in the pipe, i.e. the soft fuel integrated machine 100 has a zero cold water function, and the user can obtain water with suitable temperature at the water point in the first time, thereby further improving the user experience.

[0108] For users who have a backwater pipe 101 installed, the external connecting pipe can include the backwater pipe 101, which can be connected with the water inlet pipe 1 and the first water outlet pipe 4 to form a circulation loop.

[0109] For users who do not have a backwater pipe 101 installed, the external connecting pipe can include a cold water pipe connected from the water inlet to the water point, i.e. the cold water pipe is used as a backwater pipe, and the cold water pipe is also connected with each water point, so that when cold water is used at the water point, the cold water pipe delivers tap water to the water point for the user to use.

[0110] In order to realize the preheating cycle of the above embodiment without the backwater pipe 101 and without conflicting with normal water use, a constant pressure backwater valve 102 can be installed in the external pipeline, specifically at the most remote water use point. For example, the most remote water use point is the basin position of the bathroom, and the constant pressure backwater valve 102 is used to connect the hot water pipe 103 and the cold water pipe connected with the first water outlet pipe 4, so as to form a preheating cycle loop. Specifically, the constant pressure backwater valve 102 is connected in parallel between the water use point. The constant pressure backwater 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 connected with the cold water pipe. When normal water use, the constant pressure backwater valve 102 is in the off state, and the first water outlet pipe 4 is not connected with the cold water pipe.

[0111] Please refer to Figure 4 or Figure 5 , the water inlet pipe 1 is provided with a water inlet, and the second connecting pipeline 72 is connected between the water inlet and the inlet of the heating mechanism 3. The second connecting pipeline 72 can be used as a bypass pipeline of the first connecting pipeline 71. As shown in Figure 4 , the connection position of the second connecting pipeline 72 and the first connecting pipeline 71 can be located downstream of the intersection point of the second water outlet pipe 5 and the first connecting pipeline 71; as shown in Figure 5 , the connection position of the second connecting pipeline 72 and the first connecting pipeline 71 can be located upstream of the intersection point of the second water outlet pipe 5 and the first connecting pipeline 71.

[0112] As shown in Figure 4 or Figure 5 , the second connecting pipeline 72 can be provided with a first valve structure 81. The first valve structure 81 is used to control the on-off of the second connecting pipeline 72. Specifically, the first valve structure 81 can be an electromagnetic valve with the function of controlling the on-off of the waterway.

[0113] As shown in Figure 4 , the second valve structure 82 is arranged on the first connecting pipeline 71 between the second water outlet pipe 5 and the heating mechanism 3. Specifically, the second valve structure 82 can be in the form of a one-way valve. In addition, the second valve structure 82 can also be in the form of an electromagnetic valve with the function of controlling the on-off of the waterway. When the second valve structure 82 is a one-way valve, it is used to ensure that the fluid is unidirectional from the softening mechanism 2 to the heating mechanism 3, so as to prevent the water in the heating mechanism 3 from flowing back to the softening mechanism 2.

[0114] Please refer to Figure 4 and Figure 6, the first valve structure 81 is open, and the second valve structure 82 is closed. In the non-circulation state, the second valve structure 82 is open, and the first valve structure 81 is closed. In the preheating circulation state, the water inlet pipe 1, the second connecting pipe 72, the first water outlet pipe 4 and the external connecting pipe form a circulation loop, and a circulation pump 9 is arranged in the circulation loop.

[0115] When the hot water outlet of the water using point is in the closed state, it indicates that the user has no demand for hot water, at this time, the softener integrated machine 100 can start the preheating function through automatic switching or manual operation of the display preheating function key, at this time, the softener integrated machine enters the preheating circulation state. When the hot water outlet of the water using point is opened, it indicates that the user has a demand for hot water, at this time, the softener integrated machine 100 can automatically switch from the preheating circulation state to the non-circulation state.

[0116] When the softener integrated machine 100 is in the non-circulation state, the second valve structure 82 is open, and the first valve structure 81 is closed, which is equivalent to the second connecting pipe 72 as a bypass pipe being in the disconnected state, at this time, the working state of the softener integrated machine 100 is similar to that shown in Figure 1 , that is, the softener integrated machine 100 can provide cold soft water to the user, and can also provide hot soft water to the user. When hot soft water and cold soft water are used at the same time, the flow control device 6 throttles the cold soft water to preferentially ensure the flow of hot water and control the water temperature fluctuation of hot water.

[0117] It should be noted that when the second valve structure 82 is in different forms, the meaning of the second valve structure 82 "open" is different. Here, the second valve structure 82 open mainly means that the water flow in the first connecting pipe 71 can flow from the softening mechanism 2 to the heating mechanism 3. When the second valve structure 82 is an electromagnetic valve, the second valve structure 82 open means that the second valve structure 82 is in the open state; when the second valve structure 82 is a one-way valve, the second valve structure 82 open means that the fluid is unidirectionally open from the softening mechanism 2 to the heating mechanism 3.

[0118] When the softener and heater integrated machine 100 is in the preheating cycle state, the first valve structure 81 is in the open state, the second valve structure 82 is in the closed state, and the second connecting pipeline 72 as a bypass pipeline is in the open state. Since 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 the cycle, the tap water entering from the water inlet is preferentially passed through the second connecting pipeline 72 into the heating mechanism 3, that is, in the preheating cycle state, the circulating water is tap water entering from the water inlet. In addition, when the softener and heater integrated machine 100 is in the preheating cycle state, the second water outlet pipe 5 is opened, and cold soft water can be provided to the user. After the second water outlet pipe 5 is opened, the cold water injected from the water inlet pipe 1 is divided into two paths, one path enters the softening mechanism 2 and is output from the second water outlet pipe 5, and the other path is injected into the heating mechanism 3 from the second connecting pipeline 72. At this time, the water pressures on both sides of the second valve structure 82 are basically the same.

[0119] As shown in Figure 6 When the softener and heater integrated machine 100 is in the preheating cycle state, a circulation loop can be formed in the softener and heater integrated machine 100. Specifically, the circulation loop can 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. A circulating pump 9 can be arranged in the circulation loop. The circulating pump 9 can pressurize the fluid in the circulation loop and provide power for the circulation flow. Specifically, the circulating pump 9 can be located in the housing 110 of the softener and heater integrated machine 100, close to the water inlet pipe 1 at the bottom of the housing 110.

[0120] Taking the tap water entering the water inlet pipe 1 as the starting point, the water to be preheated first flows through the circulating pump 9, then enters the second connecting pipeline 72, part of the first connecting pipeline, and then enters the heating mechanism 3 for heating. Then, the water flows out from the first water outlet pipe 4, flows to the external pipeline, and then returns to the water inlet pipe 1, completing a cycle. The water returning to the water inlet pipe 1 again undergoes the above cycle until the temperature in the external pipeline reaches the set temperature.

[0121] When the softener and heater integrated machine 100 is in the non-circulation state, for the scenario where the external pipeline is provided, the external pipeline is in the disconnected state, for example, the constant pressure backwater valve 102 is in the disconnected state.

[0122] In addition, Figure 4 As shown in the figure, when the softener and heater integrated machine 100 is in the non-circulation mode, the circulating pump 9 can also be started; or as Figure 1As shown, the soft water burning integrated machine 100 is not provided with external pipeline, and the soft water burning integrated machine 100 can also be provided with a circulating pump 9. When the user has a large water demand, for example, the hot water device and the electric appliance requiring cold soft water work at the same time, the first water outlet pipe 4 and the second water outlet pipe 5 simultaneously discharge water, and the circulating pump 9 can be started to increase the pressure, so as to compensate the flow of the hot water end, prevent the water temperature fluctuation caused by the decrease of the flow of the hot water end, or the flow of the hot water end is too small, causing the heating mechanism 3 to be extinguished.

[0123] As shown in the embodiment, the soft water burning integrated machine 100 is provided with a first valve structure 81 and a second valve structure 82. Figure 4 Or Figure 6 The third valve structure 83 can also be provided on the water inlet pipe 1. The third valve structure 83 can be in the form of an electromagnetic valve having a water path on-off function. When the soft water is in a use state or a usable state (for example, the resin is in a non-regeneration process), the third valve structure 83 can be in a normally open state, and when the resin is in a regeneration process, the third valve structure 83 is in a closed state.

[0124] As shown in the embodiment, the soft water burning integrated machine 100 is provided with a first valve structure 81 and a second valve structure 82. Figure 5 The third valve structure 83 can also be provided on the water inlet pipe 1. The third valve structure 83 can be in the form of an electromagnetic valve having a water path on-off function. When the soft water burning integrated machine 100 is in a circulating mode, the third valve structure 83 can be in a closed state, and the first valve structure 81 is in a conductive state; when the soft water burning integrated machine 100 is in a non-circulating mode, the third valve structure 83 can be in a conductive state, and the first valve structure 81 is in a closed state.

[0125] In an embodiment, for the soft water burning integrated machine 100 with zero cold water function, in the non-circulating state, the flow control device 6 can be in the first state or the second state; in the preheating circulating state, the flow control device 6 can be in the second state or a third state, and the flow through the second water outlet pipe 5 in the third state is less than the flow through the second water outlet pipe 5 in the second state.

[0126] Please refer to Figure 4 and Figure 6 When the soft water burning integrated machine 100 is in a non-circulating state, the flow control device 6 can be in a first state or a second state. Due to the different specific forms of the flow control device 6, the specific forms of the first state and the second state are also different. In this embodiment, the flow control device 6 is taken as an example of a flow regulating valve (for example, PSG) with stepless adjustable opening degree for expansion.

[0127] Please refer to Figure 7When the soft water integrated machine 100 is in the non-circulation state, the flow control device 6 can be in different states based on different water usage. For example, when the obtained water flow indicates that the current user uses only cold soft water, the flow control device 6 is in a first state, and the PSG valve is in a fully open state (i.e., 0°). When the obtained water flow indicates that only hot soft water is used, the flow control device 6 is controlled to be in a second state, for example, the PSG valve can be at a first angle θ1, so that when cold soft water is used subsequently, the flow is limited in time to prevent large fluctuations in the water temperature of the first outlet pipe 4. When the obtained water flow indicates that cold soft water and hot soft water are used simultaneously, the flow control device 6 is controlled to be in a second state, specifically, the PSG valve can be at a first angle θ1 to prevent large fluctuations in the water temperature of the first outlet pipe 4. The value of the first angle θ1 is not specifically limited herein, for example, the first angle θ1 can be 65°.

[0128] When cold soft water and hot soft water are used simultaneously, the PSG valve can be at a first angle θ1 (e.g., 65°) as an initial flow limiting angle, and during subsequent use, the angle of the PSG valve can be adaptively adjusted according to the user's water usage. For example, the PSG valve can automatically adjust the opening degree according to the flow of the cold and hot water end to maintain the flow of the cold and hot water end at a predetermined ratio, and overall, the flow of the hot water end is greater than that of the cold water end. The data of the predetermined ratio is not specifically limited herein, for example, the flow ratio of the hot water end to the cold water end can be 3:1.

[0129] When the soft water integrated machine 100 is in the preheating circulation state, the flow control device 6 can be in the second state or a third state, and the flow through the second outlet pipe 5 in the third state is less than the flow through the second outlet pipe 5 in the second state. Specifically, based on different water usage, the flow control device 6 can also be in different states.

[0130] For example, when the soft water integrated machine 100 is in the preheating circulation state and the cold soft water is in an unused state, the flow control device 6 can be in the second state. For example, the PSG valve can be at a first angle θ1 so that when cold and hot soft water are used subsequently, the flow is limited in time to prevent large fluctuations in the water temperature of the first outlet pipe 4.

[0131] When the softener integrated machine 100 is in the preheating cycle state, before starting the circulating pump 9, if it is identified according to the first flow detection mechanism 91 and the second flow detection mechanism 92 that the user is using cold soft water, the flow control device 6 can be controlled in the third state first. Specifically, the PSG valve can be in the second angle θ3, and then the circulating pump 9 is started to ensure the normal operation of the circulation. Especially for the circulating loop provided with the constant pressure backwater valve 102, when the user uses cold soft water, it will have a certain pressure relief effect on the circulating loop. At this time, in order to ensure that the pressure in the circulating loop can be enough to push the constant pressure backwater valve 102, the PSG valve can be further used to limit the flow, that is, to reduce the opening of the PSG valve. Wherein, the second angle θ3 is greater than the first angle θ1, and the opening of the PSG valve at the first angle is greater than the opening at the second angle. Of course, the value of the second angle θ3 is not specifically limited in this application, for example, the second angle θ3 can be 80°. Subsequently, when the hot water flow is identified by the flow detection mechanism to reach the first preset flow, the opening of the flow control device 6 can be adjusted until the cold soft water flow is maintained at the second preset flow. Thus, the flow of hot water and cold soft water can better meet the user's use requirements. Wherein, the specific values of the first preset flow and the second preset flow are not specifically limited in this application, as long as they can better meet the user's use requirements.

[0132] Based on the softener integrated machine 100 provided in the above embodiment, the present application also provides a control method of the softener integrated machine 100, wherein the softener integrated machine 100 comprises: a water inlet pipe 1 for inputting cold water; a softening mechanism 2 for softening the cold water input by the water inlet pipe 1 and flowing through the softening mechanism 2; a heating mechanism 3 for heating the cold water flowing through the heating mechanism 3; a first water outlet pipe 4 connected with the outlet of the heating mechanism 3 and outputting hot water; a second water outlet pipe 5 connected with the outlet of the softening mechanism 2 and outputting softened cold water; and a flow control device 6.

[0133] In the present application, the specific composition, connection relationship and functions of each part of the softener integrated machine 100 can refer to the specific description of the softener integrated machine 100 above, which will not be described here.

[0134] Please refer to Figure 7 and Figure 8 , wherein the control method comprises: controlling the flow control device 6 to 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.

[0135] In one embodiment, the control method can comprise the following steps:

[0136] Step S1: obtaining the flow at the water inlet pipe 1;

[0137] Step S2: obtaining the water flow rate flowing through the heating mechanism 3;

[0138] Step S3: controlling the flow control device 6 according to the flow rate at the water inlet pipe 1 and the water flow rate flowing through the heating mechanism 3.

[0139] In the embodiment, according to the above-mentioned description of the fuel-software integrated machine 100, the fuel-software integrated machine 100 is provided with the first flow rate detection mechanism 91 for detecting the flow rate at the water inlet pipe 1 and the second flow rate detection mechanism 92 for detecting the water flow rate flowing through the heating mechanism 3. The first flow rate detection mechanism 91 and the second flow rate detection mechanism 92 can be used to respectively obtain the flow rate at the water inlet pipe 1 and the water flow rate flowing through the heating mechanism 3. Of course, according to the position of the flow rate detection mechanism, the form of the flow rate obtained is also different. In the method embodiment, the first flow rate detection mechanism 91 for detecting the flow rate at the water inlet pipe 1 and the second flow rate detection mechanism 92 for detecting the water flow rate flowing through the heating mechanism 3 are taken as examples for description, and other embodiments can be similarly deduced, which will not be described here.

[0140] When the flow rate at the water inlet pipe 1 and the water flow rate flowing through the heating mechanism 3 are obtained, the controller can control the flow control device 6 according to the flow rate at the water inlet pipe 1 and the water flow rate flowing through the heating mechanism 3.

[0141] In one embodiment, the controlling the flow control device 6 according to the flow rate at the water inlet pipe 1 and the water flow rate flowing through the heating mechanism 3 comprises:

[0142] controlling the flow control device 6 to be in a first state when the water flow rate flowing through the heating mechanism 3 is equal to zero;

[0143] controlling the flow control device 6 to be in a second state when the water flow rate flowing through the heating mechanism 3 reaches a preset flow rate;

[0144] wherein the flow rate through the second water outlet pipe 5 in the first state is greater than the flow rate through the second water outlet pipe 5 in the second state.

[0145] In the embodiment, when the water flow rate Q1 flowing through the heating mechanism 3 is equal to zero and Q2 is not equal to zero, the flow control device 6 can be controlled to be in the first state. According to the specific form of the flow control device 6, the state of the flow control device 6 can also be different. Taking the PSG valve as an example, the flow control device 6 is in the first state, and the PSG valve is in the fully open state (i.e. 0°).

[0146] When the water flow rate Q1 through the heating mechanism 3 reaches the preset flow rate, the heating mechanism 3 is ignited and heated, at which time hot water and cold soft water can be used together (i.e., Q1≠Q2≠0) or hot water can be used alone (Q1=Q2); at this time, the flow control device 6 is in the second state (i.e., the flow limiting state). When the flow control device 6 is a PSG valve, the PSG valve is at the first angle θ1 (e.g., 65°).

[0147] Further, for the case of using hot water and cold soft water together, the PSG valve can also self-adjust the opening degree from the second state to maintain the cold and hot soft water end flow rate ratio r at a preset ratio, for example, 1:3. Of course, the cold and hot soft water end flow rate ratio is not limited to the above distance.

[0148] For the case of using cold water alone, i.e., the water flow rate Q1 through the heating mechanism 3 is 0 and Q2≠0, the cold soft water is used with the hot soft water turned on, and the state of the flow control device 6 can be controlled to change from the first state to the second state; the PSG valve can also self-adjust the opening degree from the second state.

[0149] Alternatively, for the case of using hot water alone (Q1=Q2), the cold soft water is used with the hot soft water turned on, and the flow control device 6 can also self-adjust the opening degree from the second state.

[0150] Further, the flow control device 6 can also be controlled according to the flow rate at the inlet pipe 1 and the water flow rate through the heating mechanism 3, which can further include: when the water flow rate through the heating mechanism 3 decreases from the preset flow rate to zero and is maintained for a predetermined time t, the flow control device 6 is controlled to reset to the first state.

[0151] In the present embodiment, when the hot soft water is stopped for a predetermined time t, it indicates that the current user can indeed not need to continue using the hot soft water, at which time the flow control device 6 can be reset to the first state. Specifically, the predetermined time t can be 10 minutes, or it can also be adjusted according to the user's usage demand, and the value of the predetermined time is not specifically limited in the present application.

[0152] Taking the flow control device 6 as an example, when the user is taking a bath, there may be a short-term action of closing the shower in the bathing process, and the user still has the demand for using hot soft water. If the water flow of the heating mechanism 3 is directly reduced from the preset flow to the full open state, once the user reopens the shower for a short time, it will cause frequent switching of the PSG valve, which will affect the service life of the PSG on the one hand, and there will also be a certain delay from the full open state to the flow limiting state, which is not conducive to guaranteeing the user's use experience. When the water flow through the heating mechanism 3 is reduced from the preset flow to zero and maintained for a predetermined time, and then the PSG valve is controlled to return to the full open state, on the one hand, it can ensure that the user can have instant supply of water with suitable temperature during the entire bathing process, and on the other hand, it can also avoid frequent switching of the PSG valve, prolonging the service life of the PSG valve.

[0153] Please refer to Figure 6 The water return pipe 101 is further connected between the first water outlet pipe 4 of the soft water heating and burning integrated machine 100 and the water inlet pipe 1. The soft water heating and burning integrated machine 100 has a preheating circulation state and a non-circulation state. The method further comprises: obtaining the state of the soft water heating and burning integrated machine 100.

[0154] When the obtained state of the soft water heating and burning integrated machine 100 is the non-circulation state, the flow control device 6 is controlled according to the flow at the water inlet pipe 1 and the water flow through the heating mechanism 3, comprising:

[0155] When the water flow through the heating mechanism 3 is equal to zero, the flow control device 6 is controlled to be in a first state;

[0156] When the water flow through the heating mechanism 3 reaches a preset flow, the flow control device 6 is controlled to be in a second state;

[0157] Wherein, the flow through the second water outlet pipe 5 in the first state is greater than the flow through the second water outlet pipe 5 in the second state.

[0158] Further, the flow control device 6 is further controlled according to the flow at the water inlet pipe 1 and the water flow through the heating mechanism 3, comprising: when the water flow through the heating mechanism 3 is reduced from the preset flow to zero and maintained for a predetermined time t, the flow control device 6 is controlled to reset to the first state.

[0159] In the embodiment, the soft-burning integrated machine 100 with zero-cold-water function is mainly described. Please refer to the specific description of the above-mentioned soft-burning integrated machine 100 embodiment. When the soft-burning integrated machine 100 has zero-cold-water function, it has a preheating circulation state and a non-circulation state. The soft-burning integrated machine 100 is provided with different water use modes corresponding to the preheating circulation state and the non-circulation state. The circulation mode is provided corresponding to the preheating circulation state, and the non-circulation water use mode is provided corresponding to the non-circulation water use mode. When the hot water outlet of the water use point is in the closed state, the soft-burning integrated machine 100 can start the circulation mode and enter the preheating circulation state; when the hot water outlet of the water use point is in the open state, the soft-burning integrated machine 100 can start the non-circulation water use mode and enter the non-circulation state.

[0160] Before the control method is executed, the water use mode detection can be performed first to obtain the state of the soft-burning integrated machine 100, and it is identified whether the current is in the preheating circulation state or the non-circulation state. After the water use mode is detected and the state of the soft-burning integrated machine 100 is obtained, the flow detection can be performed by using the flow detection mechanism.

[0161] In one case, when the obtained state of the soft-burning integrated machine 100 is the non-circulation state, the specific control logic of the flow control device 6 can refer to the specific description of the above-mentioned control method, and the present application will not be expanded here.

[0162] In another case, when the obtained state of the soft-burning integrated machine 100 is the preheating circulation state, the flow control device 6 is controlled according to the flow at the water inlet pipe 1 and the water flow through the heating mechanism 3, which includes:

[0163] When the water flow through the heating mechanism 3 is equal to the flow at the water inlet pipe 1, the flow control device 6 is controlled to be in the second state;

[0164] When the water flow through the heating mechanism 3 is not equal to the flow at the water inlet pipe 1, the flow control device 6 is controlled to be in the third state;

[0165] Among them, the flow through the second water outlet pipe 5 in the second state is greater than the flow through the second water outlet pipe 5 in the third state.

[0166] Further, the method further includes: when the time of stopping the preheating circulation state reaches a predetermined time length t, the flow control device 6 is controlled to reset to the first state.

[0167] In the embodiment, when the fuel soft all-in-one machine 100 is in the preheating cycle state, the flow control device 6 can be in the second state or the third state. The flow through the second water outlet pipe 5 in the third state is less than the flow through the second water outlet pipe 5 in the second state. Specifically, the flow control device 6 can also be in different states based on different water usage conditions.

[0168] For example, when the fuel soft all-in-one machine 100 is in the preheating cycle state and the cold soft water is in the unused state (Q2-Q1=0, i.e., Q2=0, and Q1=0 at this time), the flow control device 6 can be in the second state. For example, the PSG valve can be at the first angle θ1 so that when the cold soft water is used subsequently, the flow is limited in time to prevent large fluctuations in the water temperature of the first water outlet pipe 4.

[0169] When the fuel soft all-in-one machine 100 is in the preheating cycle state, before starting the circulating pump 9, if it is identified according to the first flow detection mechanism 91 and the second flow detection mechanism 92 that the user is using the cold soft water (Q2-Q1≠0, i.e., Q2≠0, and Q1=0 at this time), the flow control device 6 can be controlled in the third state first. Specifically, the PSG valve can be at the second angle θ3, and then the circulating pump 9 is started to ensure normal operation of the circulation. In particular, for the circulating loop provided with the constant pressure backwater valve 102, when the user uses the cold soft water, a certain pressure relief effect is generated on the circulating loop. At this time, in order to ensure that the pressure in the circulating loop is sufficient to push open the constant pressure backwater valve 102, the PSG valve can be further limited in flow, i.e., the opening of the PSG valve is reduced. The second angle θ3 is greater than the first angle θ1, and correspondingly, the opening of the PSG valve at the first angle is greater than the opening of the PSG valve at the second angle. Of course, the value of the second angle θ3 is not specifically limited in the present application, for example, the second angle θ3 can be 80°. Subsequently, when it is identified by the flow detection mechanism that the hot water flow reaches the first preset flow q1, the opening of the flow control device 6 can be adjusted until the cold soft water flow is maintained at the second preset flow q2. Thus, the flows of the hot water and the cold soft water can both better meet the use requirements of the user. The specific values of the first preset flow q1 and the second preset flow q2 are not specifically limited in the present application, as long as they better meet the use requirements of the user.

[0170] If the user uses hot water during the circulation, the circulation mode can be directly switched to the non-circulation water use mode. The specific control can be referred to the execution logic of the non-circulation mode described above, which will not be described herein again.

[0171] If the user switches from using cold soft water to using hot soft water during the cycle, the opening of the PSG valve can be adjusted to a second angle θ3, and the cycle pump 9 can be restarted. After detecting the hot water flow rate q1, the opening of the flow control device 6 can be adjusted until the cold soft water flow rate is maintained at a second preset flow rate q2.

[0172] Similarly, the flow control device 6 can return to the first state, i.e., the fully open state, after the cycle has stopped for a predetermined length of time t. In addition, when the cycle stops, the control method can further include automatically switching from the cycle mode to the non-cycle water use mode.

[0173] In a special scenario, please refer to Figure 6 and Figure 7 For the soft-burning integrated machine 100 provided with the constant pressure backwater valve 102, when the soft-burning integrated machine 100 is in the cycle mode and the second water outlet pipe 5 is discharging cold soft water, a certain amount of cold water can be mixed into the cycle loop, causing the backwater temperature to fail to reach the set temperature. At this time, the control method can include:

[0174] The hot soft water flow rate Q1, the inlet pipe 1 flow rate Q2, the inlet water temperature T1, the hot soft water temperature T2, and the backwater temperature T2' in the cycle mode are determined according to the following formula:

[0175] Q1*(T2-T1)=Q2*(T2'-T1)

[0176] In the above formula, T2' is the calculated backwater temperature, Q1 is the hot water branch flow rate, Q2 is the inlet pipe 1 flow rate, T2 is the outlet water temperature, and T1 is the inlet water temperature before the cycle.

[0177] That is, if the backwater temperature fails to reach the set temperature, the current equivalent backwater temperature can be determined by calling the running logic stored in the controller and obtaining the flow rate and temperature information, thereby preventing the soft-burning integrated machine 100 from entering a dead cycle.

[0178] Any numerical values recited herein include all values from the lower value and up to the upper value in increments of one unit, provided that there is a separation of at least 2 units between any lower value and any higher value. As an example, if a numerical value is recited as being from 1 to 90, preferably from 20 to 80, and more preferably from 30 to 70, it is intended that values such as 15 to 85, 22 to 68, 43 to 51, and 30 to 32, etc. are expressly enumerated in this specification. For values which are less than one, one unit is considered to be 0.0001, 0.001, 0.01, 0.1, as appropriate. These are only examples of what is specifically enumerated herein, and are not meant to limit the application in any way. Furthermore, the inclusion of a numerical range recited herein is not intended to exclude any gyrations from the scope of the range, as appropriately interpreted, unless the context clearly indicates otherwise.

[0179] All ranges are inclusive of the endpoints and of all numbers between the endpoints, unless otherwise indicated. "About" or "approximately," when used to describe a range, is meant to encompass the two endpoints of the range as well as all numbers in between. Thus, "about 20 to 30" is intended to cover "about 20 to about 30," including at least the specified endpoints.
