TECHNICAL FIELD
[0001] The utility model relates to the field of water boiler, especially a normal pressure and pressureless double combination heating system and water boiler. BACKGROUND
[0002] As a widely used hot water supply device in modern families, the core requirement of water boiler is to provide safe, stable and sanitary hot water. The traditional storage type water boiler generally adopts a single inner tank structure, and the water body is gradually heated by an electric heating element. However, such design has significant defects: first, the heating temperature is usually difficult to reach a complete boiling state (100℃), resulting in residual bacteria and microorganisms in the water, which is insufficient in hygiene safety; second, the mixing of cold and hot water in the same inner tank is easy to form "yin and yang water", which not only affects the stability of the outlet water temperature, but also may breed bacteria and increase the risk of water pollution in long-term use. In addition, the conventional pressure design is easy to cause splashing phenomenon due to pressure mutation when the water is discharged, which is poor in user experience, and in high altitude areas, due to the decrease of boiling point, the traditional heating method is more difficult to ensure complete sterilization of the water body, which further limits the application range of the equipment.
[0003] In recent years, in view of the above problems, the industry usually adopts a double tank structure to optimize the thermal efficiency. However, the double tank design focuses on energy saving and rapid heating, and does not solve the problem of coordinated control of normal pressure heating and pressureless constant temperature, and how to avoid splashing or adapt to high altitude environment.
[0004] Therefore, the technical personnel in the art urgently need a new heating system which can not only ensure complete boiling sterilization of the water body, but also eliminate the hidden danger of cold and hot mixing through pressure separation design, while considering the adaptability to high altitude and the stability of outlet water, to meet the multiple demands of users for drinking water hygiene, safety and comfort.

[0007] A pressureless constant temperature inner tank, which is used for storing water flowing from the normal pressure heating inner tank; a plurality of water outlets and an electric exhaust switch linked with the water outlets are arranged on the pressureless constant temperature inner tank, the electric exhaust switch is opened at the same time when the water outlets are opened, and the electric exhaust switch is also closed at the same time when the water outlets are closed; the water outlets are arranged below the pressureless constant temperature inner tank;
[0008] A heat exchanger connected with the normal pressure heating inner tank and the pressureless constant temperature inner tank, the heat exchanger has an inlet for water inlet and an outlet for water outlet; the inlet of the heat exchanger is connected with the normal pressure heating inner tank and a water supply pipeline, and the outlet is connected with the pressureless constant temperature inner tank;
[0009] The temperature regulating valve connects the inlet and outlet of the heat exchanger and is used to regulate the water temperature entering the unpressurized thermostatic inner tank.
[0010] A one-way exhaust valve is located above the pressureless thermostatic inner liner to release gas and maintain the pressure inside the pressureless thermostatic inner liner consistent with the external pressure.
[0011] Furthermore, a high-temperature inner liner exhaust valve is provided above the atmospheric pressure heating inner liner, which is used to automatically exhaust air when the pressure inside the atmospheric pressure heating inner liner exceeds a set threshold.
[0012] Furthermore, the atmospheric pressure heating inner liner is equipped with a high-temperature protector, which is used to cut off the heating power supply when the temperature exceeds a set threshold.
[0013] Furthermore, the atmospheric pressure heating inner tank is equipped with an upper temperature probe and a lower temperature probe. The upper temperature probe is used to monitor the temperature of the hot water in the upper part of the inner tank, and the lower temperature probe is used to monitor the temperature of the cold water entering the bottom of the inner tank.
[0014] Furthermore, the atmospheric pressure heating inner tank is equipped with a water level probe, which is electrically connected to the tap water switch.
[0015] Furthermore, the pressureless constant temperature inner tank is equipped with an upper water level gauge and a lower water level gauge. The upper water level gauge is used to monitor the water level at the top of the inner tank, and the lower water level gauge is used to monitor the water level at the bottom of the inner tank.
[0016] It also includes a high-temperature solenoid valve, which is located at the inlet of the pressureless thermostatic inner tank and is electrically connected to the upper and lower water level gauges to control the flow of water.
[0017] Furthermore, the pressureless thermostatic inner tank is equipped with a temperature probe and a heating tube. The temperature probe is electrically connected to the heating tube and is used to detect the water temperature in real time. When the water temperature is lower than the set value, the heating tube can be activated to heat the water in the pressureless thermostatic inner tank.
[0018] Furthermore, both the atmospheric pressure heating inner liner and the pressureless constant temperature inner liner are provided with drain outlets at the bottom, and the drain outlets are connected to the external drainage system through pipes.
[0019] Furthermore, it also includes a water purifier, one end of which is connected to the tap water inlet, and the other end is connected to the atmospheric pressure heating inner tank; a safety valve is provided between the water purifier and the atmospheric pressure heating inner tank.
[0020] This utility model also provides a water heater, which is equipped with the above-mentioned dual-combination heating system of normal pressure and no pressure.
[0021] Compared with existing technologies, this utility model provides a dual-combination heating system with both atmospheric and unpressurized pressure. Through a separate design of an atmospheric-pressure heating inner tank and an unpressurized constant-temperature inner tank, combined with the coordinated control of a heat exchanger and a temperature control valve, it achieves full-process optimization from high-temperature sterilization to constant-temperature output.

This avoids the problem of "mixed hot and cold water" and dynamically balances the hot and cold water ratio through a temperature regulating valve. The outlet is linked to an electric vent switch to ensure stable water temperature and prevent splashing, significantly improving user comfort and safety, making it suitable for use in high-altitude areas.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0032] To address the problems of traditional water heaters that easily create "yin-yang water" when hot and cold water are mixed, splashing at the outlet during use, and the inability to reach the boiling point due to low pressure in high-altitude areas.
[0033] like Figure 1 As shown, this utility model provides a dual-combination heating system with both atmospheric and unpressurized pressure, comprising:
[0034] The inner tank 10 is heated under normal pressure and has a heating tube 60 inside for heating water to boiling.
[0035] The pressureless thermostatic inner tank 20 is used to store water flowing in from the atmospheric pressure heated inner tank 10; it is provided with several water outlets 22 and an electric exhaust switch 27 linked to them. When the water outlets 22 are opened, the electric exhaust switch 27 is opened at the same time, and when the water outlets 22 are closed, the electric exhaust switch 27 is also closed at the same time; the water outlets 22 are located below the pressureless thermostatic inner tank 20.
[0036] A heat exchanger 30 connects the atmospheric pressure heated inner tank 10 and the pressureless constant temperature inner tank 20. The heat exchanger 30 has an inlet for water inlet and an outlet for water outlet. The inlet of the heat exchanger 30 is connected to the atmospheric pressure heated inner tank 10 and the water supply pipeline, and the outlet is connected to the pressureless constant temperature inner tank 20.
[0037] Temperature regulating valve 31 connects the inlet and outlet of heat exchanger 30 and is used to regulate the water temperature entering the unpressurized thermostatic inner tank 20.
[0038] A one-way exhaust valve 21 is located above the pressureless thermostatic inner liner 20 and is used to exhaust gas to keep the internal pressure of the pressureless thermostatic inner liner 20 consistent with the external pressure.
[0039] Specifically, in use, such as Figure 1 As shown, when the tap water switch is turned on, tap water enters the atmospheric pressure heating inner tank 10. The heating tube 60 inside the atmospheric pressure heating inner tank 10 is activated, heating the water in the inner tank to a boiling state of 100°C. The high-temperature water after boiling flows into the heat exchanger 30 through the inlet. At the same time, purified water from the water supply pipeline enters through the other inlet of the heat exchanger 30. The high-temperature water and purified water undergo countercurrent heat exchange in the heat exchanger 30. After the high-temperature water cools down, it flows to the pressureless thermostatic inner tank 20. The temperature regulating valve 31 dynamically adjusts the mixing ratio of warm and hot water according to the user-set temperature, so that the water temperature entering the pressureless thermostatic inner tank 20 is precisely controlled within the target range.
[0040] Temperature-controlled water enters the unpressurized thermostatic inner tank 20, where it maintains pressure equilibrium with the outside environment through a one-way vent valve 21 at the top. When the user opens the outlet 22, the linked electric vent switch 27 activates simultaneously, releasing residual gas inside the inner tank to ensure stable pressure at the outlet 22 and prevent splashing. Water flows out from the outlet 22 at the bottom of the unpressurized thermostatic inner tank 20. Because the inner tank is unpressurized and the outlet 22 is located at the bottom, the water flow is smooth and splash-free. During the water output process, the heat exchanger 30 continuously replenishes the unpressurized thermostatic inner tank 20 with temperature-controlled water, maintaining a constant water level and temperature.
[0041] In one embodiment, such as Figure 1 As shown, a high-temperature inner liner exhaust valve 11 is provided above the atmospheric pressure heating inner liner 10, which is used to automatically exhaust air when the pressure inside the atmospheric pressure heating inner liner 10 exceeds a set threshold.
[0042] In the above scheme, a high-temperature inner tank exhaust valve 11 is installed to prevent dangerous situations from occurring due to excessive pressure inside the atmospheric pressure heated inner tank 10 after the water boils.
[0043] In one embodiment, such as Figure 1 As shown, the atmospheric pressure heating inner liner 10 is equipped with a high temperature protector 15, which can monitor the internal temperature of the inner liner in real time and automatically cut off the power supply when the temperature exceeds the threshold.
[0044] In one embodiment, such as Figure 1 As shown, the atmospheric pressure heating inner tank 10 is equipped with an upper temperature probe 13 and a lower temperature probe 14. The upper temperature probe 13 is used to monitor the temperature of the hot water in the upper part of the inner tank, and the lower temperature probe 14 is used to monitor the temperature of the cold water entering the bottom of the inner tank.
[0045] During use, since hot water is lighter than cold water, it will float to the top of the inner tank. Therefore, the upper temperature probe 13 can accurately reflect the actual temperature when the user uses hot water. The lower temperature probe 14 is used to monitor the temperature of the cold water at the bottom of the inner tank. When cold water enters the inner tank, the lower temperature probe 14 can detect the temperature change of the cold water, thereby better controlling the heating process.
[0046] In one embodiment, such as Figure 1 As shown, the atmospheric pressure heating inner tank 10 is equipped with a water level probe 12, which is electrically connected to the tap water switch.
[0047] In use, the water level probe 12 is used to monitor the water level of the atmospheric pressure heating inner tank 10. When the water level is too high, the tap water switch is closed to cut off the water flow into the atmospheric pressure heating inner tank 10; when the water level is too low, the tap water switch is opened to allow water to flow into the atmospheric pressure heating inner tank 10.
[0048] In one embodiment, such as Figure 1 As shown, the pressureless constant temperature inner tank 20 is equipped with an upper water level gauge 23 and a lower water level gauge 24. The upper water level gauge 23 is used to monitor the water level at the top of the inner tank, and the lower water level gauge 24 is used to monitor the water level at the bottom of the inner tank.
[0049] It also includes a high-temperature solenoid valve 26, which is located at the inlet of the pressureless thermostatic inner tank 20 and is electrically connected to the upper water level gauge 23 and the lower water level gauge 24 to control the flow of water.
[0050] During use, the water level of the pressureless thermostatic inner tank 20 is monitored by the upper and lower water level gauges. When the water level is too high, the high temperature solenoid valve 26 closes, cutting off the water flow into the pressureless thermostatic inner tank 20; when the water level is too low, the high temperature solenoid valve 26 opens, allowing water to flow into the pressureless thermostatic inner tank 20.
[0051] In one embodiment, such as Figure 1 As shown, the pressureless thermostatic inner tank 20 is equipped with a temperature probe 25 and a heating tube 60. The temperature probe 25 is electrically connected to the heating tube 60 and is used to detect the water temperature in real time. When the water temperature is lower than the set value, the heating tube 60 can be activated to heat the water in the pressureless thermostatic inner tank 20.
[0052] In one embodiment, such as Figure 1 As shown, both the atmospheric pressure heating inner liner 10 and the pressureless constant temperature inner liner 20 are provided with a drain outlet 70 at the bottom, and the drain outlet 70 is connected to the external drainage system through a pipe.
[0053] Drainage outlets 70 are provided at the bottom of the atmospheric pressure heating inner liner 10 and the pressureless constant temperature inner liner 20 to completely drain the water accumulated in the inner liner for daily maintenance and to prevent the accumulation of internal impurities.
[0054] In one embodiment, such as Figure 1As shown, it also includes a water purifier 50, one end of which is connected to a tap water inlet and the other end is connected to a normal pressure heating inner tank 10; a safety valve 40 is provided between the water purifier 50 and the normal pressure heating inner tank 10.
[0055] Using the above solution, tap water can be filtered by water purifier 50 before entering the atmospheric pressure heating inner tank 10, thus preventing impurities from entering the inner tank and improving water quality; the safety valve 40 can prevent backflow of water entering the water heater.
[0056] This utility model also provides a water heater, which is equipped with the above-mentioned dual-combination heating system of normal pressure and no pressure.
[0057] In summary, this utility model provides a dual-combination heating system with both atmospheric and unpressurized pressure. Through a separate design of the atmospheric pressure heating inner tank and the unpressurized constant-temperature inner tank, combined with the coordinated control of a heat exchanger and a temperature control valve, it achieves full-process optimization from high-temperature sterilization to constant-temperature output. When the atmospheric pressure heating inner tank is heated by the heating tube, the internal pressure increases, continuously maintaining the water at a boiling state, thoroughly killing microorganisms and solving the problem of traditional water heaters failing to reach the boiling point due to insufficient heating temperature or in high-altitude areas. The unpressurized constant-temperature inner tank uses a one-way vent valve to maintain consistent internal and external pressure, and works with the heat exchanger to gradually cool the high-temperature boiling water. This avoids the problem of "mixed hot and cold water" and dynamically balances the hot and cold water ratio through a temperature regulating valve. The outlet is linked to an electric vent switch to ensure stable water temperature and prevent splashing, significantly improving user comfort and safety, making it suitable for use in high-altitude areas.
[0058] Although this document frequently uses terms such as atmospheric pressure heating inner liner, unpressurized thermostatic inner liner, heat exchanger, temperature regulating valve, one-way exhaust valve, and high-temperature protector, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
