[0003] To solve this problem, some water heaters on the market have added a softening regeneration device at the front end of the heating device. Although this setting can soften hard water, the brine in the softening stage will enter the heating device, accelerate the corrosion of the heating device, and affect the service life of the water heater.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] It should also be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0040] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0041] like Figure 1 As shown, one embodiment of the present invention proposes a water heater, including a heating device 10, a softening and regenerating device 20 and a first pipeline 30, the heating device 10 has a first water inlet 11 and a first water outlet 12, the softening and regenerating device 20 has a second water inlet 21 and a second water outlet 22, one end of the first pipeline 30 is connected to the first water outlet 12, and the other end is connected to the second water inlet 21, and the softening and regenerating device 20 is used to soften the initial water passing through the heating device 10 into softened water.

[0042] In specific use, the initial water, which may be tap water, enters the heating device 10 through the first water inlet 11 for heating, and the heated initial water enters the softening regeneration device 20 through the first pipeline 30 for softening, and the softened water formed after softening flows out from the second water outlet 22 for bathing and other purposes. It should be noted that the initial water from the heating device 10 may be heated hot water or unheated cold water.

[0043] After adopting the above technical solution, the initial water passing through the heating device 10 is softened by setting the softening and regeneration device 20, and the user can use softened water for bathing, thereby improving the user experience. Moreover, by setting the softening and regeneration device 20 in a post-position, the salt water used in the regeneration of the softening and regeneration device 20 will not enter the heating device 10, thereby avoiding the situation where the salt water accelerates the corrosion of the heating device 10, thereby extending the service life of the water heater.

[0044] like Figure 2 As shown, in some other embodiments, the water heater includes a heating device 10, a softening and regenerating device 20, a first pipeline 30 and a mixing device 40, the heating device 10 has a first water inlet 11 and a first water outlet 12, the softening and regenerating device 20 has a second water inlet 21 and a second water outlet 22, one end of the first pipeline 30 is connected to the first water outlet 12, and the other end is connected to the second water inlet 21, the mixing device 40 is arranged between the heating device 10 and the softening and regenerating device 20, the mixing device 40 has a first inlet 41, a second inlet 42 and a mixed water outlet 43, the mixed water outlet 43 is connected to the second water inlet 21, the first inlet 41 is connected to the first water outlet 12, the second inlet 42 is used to input cold initial water, and the mixing device 40 is used to adjust the water temperature of the initial water entering the softening and regenerating device 20.

[0045] During specific use, the hot water coming out of the heating device 10 enters the mixing device 40 through the first pipeline 30, and the cold initial water enters the mixing device 40 through the second inlet 42. The hot water and the cold water are mixed in the mixing device 40, so that the water temperature of the initial water entering the softening regeneration device 20 is adjusted to a preset temperature value.

[0046] After adopting the above technical solution, by setting the softening and regeneration device 20 to soften the initial water passing through the heating device 10, the user can use softened water for bathing, thereby improving the user experience. Moreover, by setting the softening and regeneration device 20 in a post-position, the salt water used in the regeneration of the softening and regeneration device 20 will not enter the heating device 10, thereby avoiding the situation where the salt water accelerates the corrosion of the heating device 10, thereby extending the service life of the water heater. In addition, by setting the mixing device 40 to adjust the water temperature entering the softening and regeneration device 20, it is possible to avoid the initial water temperature coming out of the heating device 10 being too high to cause damage to the materials inside the softening and regeneration device 20, thereby extending the service life of the softening and regeneration device 20.

[0047] like Figure 2 As shown, in some embodiments, the water heater further includes a water inlet pipe 50 , which includes a third water inlet 51 and two third water outlets 52 , wherein one third water outlet 52 is connected to the first water inlet 11 , and the other third water outlet 52 is connected to the second inlet 42 .

[0048] During specific use, the initial water entering the water inlet pipe 50 from the third water inlet 51 has two paths, one path enters the heating device 10 through the first water inlet 11 , and the other path enters the mixing device 40 through the second inlet 42 .

[0049] With this design, the pipe connection can be simplified, the space occupied by components can be saved, and the size of the water heater can be reduced.

[0050] like Figure 3 As shown, the water inlet pipe 50 of the water heater is not limited to the above-mentioned method. In some other embodiments, the water heater includes a first water inlet pipe 50a and a second water inlet pipe 50b. The first water inlet pipe 50a is connected to the first water inlet 11, and the second water inlet pipe 50b is connected to the second inlet 42.

[0051] During specific use, initial water enters the heating device 10 from the first water inlet pipe 50a and enters the mixing device 40 from the second water inlet pipe 50b.

[0052] In this design, the heating device 10 and the mixing device 40 are independently supplied with water, and the water supply is stable.

[0053] Optionally, the mixing device 40 is an electrically controlled thermostatic valve.

[0054] like Figure 4 As shown, the water heater may not be provided with the mixing device 40. For example, in some embodiments, the heating device 10 includes an inner tank 10a, a heating component 10b and a thermostatic component 10c. The inner tank 10a is used to hold initial water, the heating component 10b is installed on the inner tank 10a and is used to heat the initial water, and the thermostatic component 10c is arranged at the first water outlet 12 and is used to output hot water at a constant temperature. The heating component 10b may be a heating wire wound around the outer wall of the inner tank 10a, or may be a heating wire extending into the inner tank 10a, depending on actual design requirements.

[0055] In this embodiment, since the heating device 10 is provided with a constant temperature component 10 c and can adjust the temperature itself, there is no need to provide a mixing device 40 .

[0056] In this design, since the mixing device 40 is not provided, not only the space occupied by the mixing device 40 is reduced, but also the connection of components is simplified.

[0057] like Figure 4As shown, in some embodiments, when the water heater is not provided with a mixing device 40 , another third water outlet 52 of the water inlet pipe 50 is connected to the second water inlet 21 .

[0058] like Figure 5 As shown, of course, in this embodiment, the water inlet pipe 50 can also adopt the above-mentioned setting method including the first water inlet pipe 50a and the second water inlet pipe 50b, the first water inlet pipe 50a is connected to the first water inlet 11, and the second water inlet pipe 50b is connected to the second water inlet 21.

[0059] like Figure 6 and Figure 7 As shown, in some other embodiments, the water heater includes a heating device 10, a softening and regenerating device 20, a first pipeline 30, a second pipeline 60 and a control valve assembly 70, the heating device 10, the softening and regenerating device 20, the first pipeline 30 and the mixing device 40, the heating device 10 has a first water inlet 11 and a first water outlet 12, the softening and regenerating device 20 has a second water inlet 21 and a second water outlet 22, one end of the first pipeline 30 is connected to the first water outlet 12, and the other end is connected to the second water inlet 21, one end of the second pipeline 60 is connected to the first water outlet 12, and the other end is connected to the second water outlet 22, the control valve assembly 70 is connected to the softening and regenerating device 20 and the second pipeline 60, and the control valve assembly 70 is used to control the water supply ratio of the softening and regenerating device 20 and the second pipeline 60.

[0060] With this design, the water heater can provide at least three water use modes for customers to choose from. One of the water use modes is that the control valve assembly 70 controls the softening and regeneration device 20 to cut off the flow, controls the second pipeline 60 to flow, and the water heater supplies hot water and hard water. Another water use mode is that the control valve assembly 70 controls the second pipeline 60 to cut off the flow, controls the softening and regeneration device 20 to flow, and the water heater supplies hot water and soft water. Another water use mode is that the control valve assembly 70 first controls the softening and regeneration device 20 to cut off the flow, and the second pipeline 60 to flow, and then controls the second pipeline 60 to cut off the flow, and the softening and regeneration device 20 to flow, and the water heater supplies hot water and hard water first and then hot water and soft water.

[0061] After adopting the above technical solution, by setting the softening and regeneration device 20 to soften the initial water passing through the heating device 10, the user can use softened water for bathing, which improves the user experience. Moreover, by setting the softening and regeneration device 20 in a post-position, the salt water used in the regeneration of the softening and regeneration device 20 will not enter the heating device 10, avoiding the situation where the salt water accelerates the corrosion of the heating device 10, and extending the service life of the water heater. In addition, by setting the second pipeline 60 and the control valve assembly 70, the user can choose different water hardness and water outlet modes according to personal preferences for bathing and other purposes, and the user experience is good.

[0062] like Figure 6As shown, in some embodiments, the control valve assembly 70 includes a first control valve 71 and a second control valve 72, the first control valve 71 is connected to the second water inlet 21, and the first control valve 71 is used to control the water supply ratio of the softening regeneration device 20, and the second control valve 72 is connected to the second pipeline 60, and the second control valve 72 is used to control the water supply ratio of the second pipeline 60. Of course, the first control valve 71 can also be set to be connected to the second water outlet 22, depending on the actual design needs.

[0063] In some embodiments, at least one of the first control valve 71 and the second control valve 72 is a regulating valve.

[0064] Exemplarily, the first control valve 71 is a stop valve and the second control valve 72 is a regulating valve, or the first control valve 71 is a regulating valve and the second control valve 72 is a stop valve, or both the first control valve 71 and the second control valve 72 are regulating valves.

[0065] After adopting the above technical solution, by setting at least one of the first control valve 71 and the second control valve 72 as a regulating valve, the initial water and softened water can be mixed in a preset ratio, and the user can use hot water mixed water with preset water hardness according to personal preference.

[0066] Of course, the first control valve 71 and the second control valve 72 may both be stop valves. In this embodiment, the water heater cannot provide hot water mixed water with precise water hardness.

[0067] like Figure 6 As shown, in some embodiments, one end of the second pipeline 60 is connected to the first pipeline 30, and the second pipeline 60 is connected to the first water outlet 12 through the first pipeline 30. This design method can simplify the pipeline connection. Of course, the second pipeline 60 can also be directly connected to the first water outlet 12.

[0068] like Figure 6 As shown, in some embodiments, the first pipeline 30 and the second pipeline 60 have a connection point A, and the mixing device 40 is disposed between the first water outlet 12 and the connection point A.

[0069] like Figure 7As shown, the control valve assembly 70 is not limited to the above-mentioned configuration including the first control valve 71 and the second control valve 72. In some other embodiments, the control valve assembly 70 includes a mixing valve 70a, and the second pipeline 60 and the second water outlet 22 are both connected to the mixing valve 70a. The initial water of the second pipeline 60 and the softened water of the second water outlet 22 are mixed at the mixing valve 70a. The mixing valve 70a provides different water use modes for the user by controlling the water supply ratio of the softening regeneration device 20 and the second pipeline 60. When the mixing valve 70a controls the softening regeneration device 20 to cut off, the water heater supplies hot water hard water flowing through the second pipeline 60. When the mixing valve 70a controls the second pipeline 60 to cut off, the water heater supplies hot water soft water flowing through the softening regeneration device 20. When the mixing valve 70a controls the opening connected to the softening regeneration device 20 and the opening connected to the second pipeline 60 to open according to a certain ratio, the water heater supplies hot water mixed water.

[0070] like Figure 8 and Fig. 9 As shown, in some other embodiments, the water heater includes a heating device 10, a softening and regenerating device 20, a first pipeline 30, a mixing device 40, a water inlet pipe 50, a second pipeline 60 and a control valve assembly 70.

The mixing device 40 is arranged between the heating device 10 and the softening and regenerating device 20, and the mixing device 40 has a first inlet 41, a second inlet 42 and a mixed water outlet 43, the mixed water outlet 43 is connected to the second water inlet 21, and the first inlet 41 is connected to the first water outlet 12. The water inlet pipe 50 includes a third water inlet 51 and two third water outlets 52, one of the third water outlets 52 is connected to the first water inlet 11, and the other third water outlet 52 is connected to the second inlet 42. One end of the second pipeline 60 is connected to the first pipeline 30 between the mixing device 40 and the softening and regenerating device 20, and the other end is connected to the second water outlet 22. The control valve assembly 70 is connected to the softening and regenerating device 20 and the second pipeline 60, and the control valve assembly 70 is used to control the water supply ratio between the softening and regenerating device 20 and the second pipeline 60.

[0071] The control valve assembly 70 is combined with the water inlet pipe 50 and the mixing device 40, so that the water heater has four other water use modes. In one water use mode, the initial water enters the mixing device 40 through the third water outlet 52 of the water inlet pipe 50, and then enters the softening regeneration device 20 through the first pipeline 30, and the water heater supplies cold soft water. Another water use mode is that the initial water enters the mixing device 40 through the third water outlet 52 of the water inlet pipe 50, and then enters the second pipeline 60 through the first pipeline 30, and the water heater supplies cold hard water. Another water use mode is that the initial water enters the mixing device 40 through the third water outlet 52 of the water inlet pipe 50, and then enters the softening regeneration device 20 and the second pipeline 60 through the first pipeline 30, and then mixes to obtain cold mixed water. Another water use mode is that the initial water enters the mixing device 40 through the third water outlet 52 of the water inlet pipe 50, and then enters the second pipe 60 through the first pipe 30, and the water heater supplies cold hard water. Then, the initial water enters the mixing device 40 through the third water outlet 52 of the water inlet pipe 50, and then enters the softening regeneration device 20 through the first pipe 30, and the water heater supplies cold soft water. That is, the water heater first supplies cold hard water and then supplies cold soft water.

[0073] After adopting the above technical solution, by setting up the softening and regeneration device 20 to soften the initial water passing through the heating device 10, the user can use softened water for bathing, thereby improving the user experience. Moreover, by setting up the softening and regeneration device 20 in a post-position, the brine used when the softening and regeneration device 20 is regenerated will not enter the heating device 10, thereby avoiding the situation where the brine accelerates the corrosion of the heating device 10, thereby extending the service life of the water heater. In addition, by setting up a first water quality hardness detector 101 to detect the water quality hardness of the softened water flowing out of the second water outlet 22, and then displaying it by connecting to a display screen, it is convenient for the user to know the water quality hardness of the softened water flowing out of the softening and regeneration device 20, and to regenerate the softening and regeneration device 20 in time.

[0081] In the softening stage, the initial water from the heating device 10 enters the softening regeneration device 20, and the calcium and magnesium ions in the initial water are adsorbed by the resin, and the initial water is softened into softened water. In the regeneration stage, the sodium chloride solution in the regeneration component 24 enters the softening component 23, and the sodium ions in the sodium chloride solution replace the calcium and magnesium ions on the resin. The replaced calcium and magnesium ions are discharged from the waste outlet 200 of the softening regeneration device 20, and the resin regains activity.

[0083] After adopting the above technical solution, by setting the softening and regeneration device 20 to soften the initial water passing through the heating device 10, the user can use softened water for bathing, thereby improving the user experience. Moreover, by setting the softening and regeneration device 20 in a post-position, the salt water used in the regeneration of the softening and regeneration device 20 will not enter the heating device 10, thereby avoiding the situation where the salt water accelerates the corrosion of the heating device 10, thereby extending the service life of the water heater. In addition, by adding a purification device 90 at the water inlet pipe 50, the purification device 90 can effectively avoid at least one of the following problems: scaling of the heating device 10, accelerated corrosion of the heating device 10, and the presence of pathogens in the initial water by purifying the initial water.

[0084] like Fig.13 As shown, in some embodiments, the purification device 90 includes a housing and a scale-inhibiting component disposed inside the housing. By providing the scale-inhibiting component, impurities in the initial water flowing through the water inlet pipe 50 can be filtered to prevent the impurities from entering the heating device 10 to form a scale layer.

[0085] like Fig.13As shown, in some embodiments, the anti-scaling component includes a filter screen and an anti-scaling filter element, and the initial water enters the heating device 10 after passing through the filter screen and the anti-scaling filter element in sequence. Among them, the filter screen is a textile fiber filter screen or a metal filter screen, which is used to filter dust and other foreign particles in the external tap water. Optionally, the anti-scaling filter element can be one of an activated carbon filter element, a ceramic filter element and a resin filter element. By setting up double filtration of the filter screen and the anti-scaling filter element, the silt, bacteria, rust and calcium and magnesium ions in the initial water can be effectively filtered out, reducing the scale layer generated in the heating device 10.

[0086] like Fig.13 As shown, in some embodiments, the purification device 90 includes a housing and a dechlorination component disposed inside the housing. The residual chlorine produces chloroform after being heated by the heating device 10. Even if it is absorbed at a low concentration for a long time, it will cause considerable chronic damage. For children, the residual chlorine in the water will cause their hair to become dry, broken, and split, and will also cause skin bleaching, skin layer shedding, and allergies; for the elderly, chlorine will produce carcinogens such as chloroform after being heated, which can easily lead to atherosclerosis, heart disease, bladder cancer, liver cancer, rectal cancer, hypertension, etc. In this embodiment, by providing a dechlorination component, the residual chlorine in the initial water can be prevented from affecting people's health.

[0087] like Fig.13 As shown, in some embodiments, the dechlorination component includes a filter element and dechlorination particles filled in the filter element, and the dechlorination particles include at least one of KDF (Kinetic Degradation Fluxion) particles, calcium sulfite particles and activated carbon particles. Among them, KDF particles use redox reactions to exchange electrons with oxidizing harmful substances in water, turning many harmful substances into harmless substances, which has the advantages of reducing mineral scaling, reducing suspended solids, removing residual chlorine, inhibiting microbial reproduction, and removing heavy metals. Calcium sulfite can effectively remove residual chlorine in water through redox reactions. Activated carbon particles have a strong adsorption effect on residual chlorine.

[0088] like Fig.13As shown, in some embodiments, the purification device 90 includes a magnetized component installed on the water inlet pipe 50. The magnetized component is used to generate a high-intensity magnetic field, which changes the physical structure of minerals in the water without changing the original chemical composition of the initial water. When the magnetic field condition reaches 3000GS-5000GS or more, the initial water is allowed to cut the magnetic field at a certain flow rate along the direction perpendicular to the magnetic field line, and ordinary water will become magnetized water. Experiments show that after the water is magnetized, a series of physical and chemical changes occur in the water properties, the hydrogen bond angle changes from 105° to 103°, the water changes from the original thirteen to eighteen large molecular clusters to five to six small molecular clusters, the permeability, solubility and surface tension of the water are enhanced, so that the traditional properties of the water have changed, and it can kill a variety of bacteria and viruses. In addition, positive and negative ions or particles collide with each other to form a certain number of "ion associations", which have sufficient stability and form a large number of crystal cores in the water, so that the water heater has the functions of scale prevention, descaling and corrosion prevention.

[0089] like Fig.13 As shown, in some embodiments, the magnetizing element is a permanent magnet or an electromagnetic induction coil, and the magnetic field direction of the magnetizing element is perpendicular to the water flow direction. By setting the magnetic field direction of the magnetizing element to be perpendicular to the water flow direction, a better magnetization effect can be formed on the initial water flowing through the magnetizing element.

[0090] Optionally, the magnetizing element is a permanent magnet in an annular shape and is embedded in the water inlet pipe 50. The initial water passes through the middle of the magnetizing element and is magnetized into magnetized water.

[0091] Optionally, the electromagnetic induction coil is wound around the outer wall of the water inlet pipe 50, and when the electromagnetic induction coil is energized, a magnetic field is generated to magnetize the initial water. It should be noted that the water inlet pipe 50 section wound by the electromagnetic induction coil is made of non-metallic material, which not only allows the magnetic field to penetrate, but also is not easily magnetized. The non-metallic materials that can be used include polyvinyl chloride, polypropylene, polytetrafluoroethylene, etc.
