[0002] As an indispensable household appliance in daily life, the technological evolution of water boilers has always been accompanied by the improvement of people's living habits and quality requirements. Traditional water boilers use electric heating elements to heat water to boiling, meeting basic drinking water needs. However, with the rise of coffee culture and tea culture, as well as modern people's pursuit of quality of life, the functional requirements of water boilers have also been upgraded.

[0003] Existing water machines cannot provide steam and drinkable water at the same time: Existing water machines often have limitations in functional design and cannot meet users' needs for steam and drinkable water at the same time. This has limited the wide application of water machines in the fields of coffee making, tea art performances, etc. to a certain extent. At the same time, traditional water machines often have high energy consumption during the heating process, which not only increases users' electricity costs, but also does not conform to the modern society's advocacy of energy conservation and environmental protection. Moreover, existing water machines often have deficiencies in temperature control and water volume control, making it difficult to achieve accurate constant temperature and quantitative production. This is undoubtedly a problem that needs to be solved urgently for users who pursue high-quality beverages.

[0007] Wherein, the water inlet component includes a TDS sensor and a diaphragm pump, the TDS sensor is connected to pure water, the diaphragm pump is connected to the TDS sensor, and the diaphragm pump is also connected to the three-way interface A.

[0008] Among them, the water distribution component includes a flow meter and a three-way interface E, the flow meter is connected to the pressure reducing valve, and the three-way interface E is connected to the flow meter, the two-position two-way solenoid valve at the heat storage end and the two-position two-way solenoid valve at the cold water end.

[0009] Among them, the preheating component includes a second one-way valve and a preheating pipe, the preheating pipe is arranged in the steam boiler, the second one-way valve is connected to the two-position two-way solenoid valve at the heat storage end and the preheating pipe, and the end of the preheating pipe away from the second one-way valve is connected to the preheating water inlet of the heat storage boiler.

Only when the water quality meets the standard can the water enter the three-way interface A after the water inlet component provides power. At this time, part of the pure water passing through the three-way interface A enters the steam boiler through the water replenishment two-position two-way solenoid valve and the first one-way valve.

The water coming out at this time is called cold drinking water; the other path of pure water passing through the water distribution component enters the preheating component through the two-position two-way solenoid valve at the heat storage end. After the water in the preheating component is preheated by the steam boiler, the basic water temperature can be increased by 20-30 degrees, and then it is heated again when entering the heat storage boiler to maintain the water temperature at 65 degrees (this temperature can be set). The preheated water enters from the preheated water inlet below the storage boiler, and the hot water flows out from the hot water outlet above the heat storage boiler. The outflow of hot water requires The water inlet assembly provides power, and the hot water in the heat storage boiler is pushed out by injecting water under the heat storage boiler. The pushed out hot water flows through the instant heating boiler, and the instant heating boiler operates according to the set program. If only 65-degree water is required, the instant heating boiler does not heat, and the warm water flows out directly from the water outlet. If the water outlet requires water temperature of 66-99 degrees, the instant heating boiler operates at the required heating temperature, and heats the 65-degree water again to the required temperature. This heating process is very fast, and finally the water that meets the standard still flows out from the water outlet. In this way, the technical problems of the water boiler in the prior art that cannot provide steam and drinkable boiled water at the same time, has high energy consumption, and is difficult to achieve constant temperature and quantitative output when actually used are solved.

[0020] The present invention provides a constant temperature and quantitative water machine system with steam, comprising a water inlet component, a three-way interface A1, a water replenishment two-position two-way solenoid valve 2, a first one-way valve 3, a steam boiler 4, a steam two-position three-way solenoid valve 5, a pressure reducing valve 6, a water distribution component, a heat storage end two-position two-way solenoid valve 7, a cold water end two-position two-way solenoid valve 8, a three-way interface B9, a water outlet 10, a preheating component, a heat storage boiler 11, an instant hot end two-position two-way solenoid valve 12, an instant hot boiler 13, a three-way interface C14, a three-way interface D15, a water accumulation box 39 and a plug 16, wherein the water inlet component is connected to pure water, the three-way interface A1 is connected to the water inlet component, the water replenishment two-position two-way solenoid valve 2 and the pressure reducing valve 6 are both connected to the three-way interface A1. 1, the water replenishment port 17 of the steam boiler 4 is connected to the water replenishment two-position two-way solenoid valve 2 through the first one-way valve 3, the two-position three-way solenoid valve is connected to the steam port 18 of the steam boiler 4, the two-position three-way solenoid valve is also connected to the built-in probe steam rod 19, and the sewage outlet of the steam boiler 4 is connected to the plug 16 through the three-way interface B 9; The water distribution component is connected to the pressure reducing valve 6, the two-position two-way solenoid valve 7 at the heat storage end and the two-position two-way solenoid valve 8 at the cold water end are both connected to the water distribution component, the two-position two-way solenoid valve 8 at the cold water end is connected to the water outlet 10 through the three-way interface C14, the preheating components are connected to the two-position two-way solenoid valve 7 at the heat storage end, the steam boiler 4 and the heat storage boiler 11, the hot water outlet 21 of the heat storage boiler 11 is connected to the two-position two-way solenoid valve 12 at the instant heating end, the instant heating boiler 13 is connected to the two-position two-way solenoid valve 12 at the instant heating end, the sewage outlet of the heat storage boiler 11 is connected to the three-way interface B 9, the three-way interface D 15 is connected to the three-way interface C 14 and the instant heating boiler 13, and the water accumulation box 39 is connected to the three-way interface B 9 and the three-way interface D 15; The steam boiler 4 is also equipped with a low water level probe 28, a high water level probe 29, a pressure relief valve 30, a vacuum breaking valve 31, a first temperature probe 32, a temperature control protector 33 and a first heating tube 34; The heat storage boiler 11 is also equipped with a second temperature probe 35 and a second heating tube 36; The capacity of the steam boiler 4 and the heat storage boiler 11 are both 4L; The instant heating boiler 13 is a 3.3KW instant heating boiler 13 .

[0021] With respect to this specific embodiment, when it is used, the water quality is first judged by the water inlet component. When the water quality does not meet the standard, an alarm is issued. Only when the water quality meets the standard can the water enter the three-way interface A1 after the water inlet component provides power. At this time, part of the pure water passing through the three-way interface A1 enters the steam boiler 4 through the water replenishment two-position two-way solenoid valve 2 and the first one-way valve 3. The steam generated by the steam boiler 4 is discharged to the steam two-position two-way solenoid valve through the steam port 18, and discharged to the built-in probe steam rod 19; At the same time, another part of the pure water passing through the three-way interface A1 enters the water distribution component and is divided into two paths. One path passes through the two-position two-way solenoid valve 8 at the cold water end and the three-way interface C14 and flows directly to the water outlet 10. The water coming out at this time is called cold drinking water; the other path of pure water passing through the water distribution component passes through the two-position two-way solenoid valve 7 at the heat storage end and enters the preheating component. After the water in the preheating component is preheated by the steam boiler 4, the basic water temperature can be increased by 20-30 degrees, and then it is heated again when entering the heat storage boiler 11 to maintain the water temperature at 65 degrees (this temperature can be set). The preheated water enters from the preheated water inlet 20 below the storage boiler, and the hot water flows out from the hot water outlet 21 above the heat storage boiler 11. The outflow of hot water requires the water inlet component to provide power, and the water is injected into the bottom of the heat storage boiler 11 to increase the water temperature. The hot water in the heat storage boiler 11 is pushed out, and the pushed out hot water flows through the instant heating boiler 13. The instant heating boiler 13 operates according to the set program. If only 65-degree water is needed, the instant heating boiler 13 does not heat, and the warm water flows out directly from the water outlet 10. If the water outlet 10 requires water with a temperature of 66-99 degrees, the instant heating boiler 13 operates at the required heating temperature to heat the 65-degree water again to the required temperature. This heating process is very fast, and finally the qualified water still flows out from the water outlet 10. In this way, the technical problems of the water boiler in the prior art that cannot provide steam and drinkable water at the same time, high energy consumption and difficulty in achieving constant temperature and quantitative output are solved when the water boiler is actually used.

[0022] The water inlet assembly includes a TDS sensor 22 and a diaphragm pump 23. The TDS sensor 22 is connected to pure water, the diaphragm pump 23 is connected to the TDS sensor 22, and the diaphragm pump 23 is also connected to the three-way interface A1.

[0023] In this specific implementation, the TDS sensor 22 is used to measure the water quality and judge the quality of the water. If the water quality does not meet the standard, the machine alarms. Only when the pure water that meets the water quality standard is detected, the machine can work normally. The diaphragm pump 23 is the power source of the whole machine: 1. Supply water to the steam boiler 4; 2. Supply water to the whole water machine system and provide the power required for water movement. Using one power source, the program control is simple, the effect is great and the cost is low.

[0024] Secondly, the water distribution component includes a flow meter 24 and a three-way interface E 25. The flow meter 24 is connected to the pressure reducing valve 6, and the three-way interface E 25 is connected to the flow meter 24, the two-position two-way solenoid valve 7 at the heat storage end and the two-position two-way solenoid valve 8 at the cold water end.

[0025] According to this specific embodiment, the flow meter 24 acts on the cold water end, and its accuracy is not affected by high temperature water (high temperature water will contain bubbles, thus affecting the flow accuracy), and is not affected by scale in the boiler (when the boiler is used for a long time and lacks maintenance, scale will be generated after heating the water).

[0026] At the same time, the preheating assembly includes a second one-way valve 26 and a preheating pipe 27. The preheating pipe 27 is arranged in the steam boiler 4. The second one-way valve 26 is connected to the two-position two-way solenoid valve 7 at the heat storage end and the preheating pipe 27. The end of the preheating pipe 27 away from the second one-way valve 26 is connected to the preheating water inlet 20 of the heat storage boiler 11.

[0027] According to this specific embodiment, when the water outlet 10 needs to discharge hot water, the pure water passing through the water distribution component enters the preheating pipe 27 through the second one-way valve 26, and is preheated by the steam boiler 4 in the preheating pipe 27. After being preheated by the preheating pipe 27, the basic water temperature can be increased by 20-30 degrees.

[0028] In addition, the steam boiler 4 is also equipped with a drug injection port plug A 37.

[0029] The heat storage boiler 11 is also provided with a medicine feeding port plug B 38.

[0030] In this specific embodiment, the main function of the drug injection port plug A 37 and the drug injection port plug B 38 is to block the drug injection ports of the steam boiler 4 and the heat storage boiler 11 to prevent the medium (such as water, steam, etc.) in the boiler from leaking out through the drug injection ports. This helps to maintain the pressure inside the boiler stable and ensure the normal operation of the boiler system.

[0031] Furthermore, the first heating tube 34 is a 2.5KW heating tube.

[0032] The second heating tube 36 is a 0.8KW heating tube.

[0033] According to the present specific embodiment, the first heating tube 34 of 2.5KW has a relatively high power and can heat a large amount of water quickly to meet the user's urgent need for boiling water or a large amount of boiling water.

[0034] The second heating tube 36 of 0.8KW has a relatively low power and is suitable for maintaining water temperature or heating a small amount of water.

[0035] When using a constant temperature and quantitative water boiler system with steam according to this embodiment, When the present invention is in use, the working principle of the heat storage boiler 11 is that the diaphragm pump 23 maintains the water pressure stably at 0.5 Bar after the pressure reduction through the pressure reducing valve 6, and the total water intake is recorded through the flow meter 24, and then divided into two paths through the three-way interface E 25, one path can directly reach the water outlet 10, and the water coming out at this time is called cold drinking water. The other path first passes through the preheating pipe 27 and then enters the heat storage boiler 11. After preheating through the preheating pipe 27, the basic water temperature can be increased by 20-30 degrees, and then heated again in the heat storage boiler 11 to maintain the water temperature at 65 degrees (this temperature can be set). The water inlet and outlet mode of the heat storage boiler 11 is as follows: preheated water enters from the preheated water inlet 20 below the heat storage boiler, and hot water flows out from the hot water outlet 21 above the heat storage boiler 11. The outflow of hot water requires power from the water inlet assembly. The hot water in the heat storage boiler 11 is pushed out by injecting water below the heat storage boiler 11. The pushed out hot water flows through the instant heating boiler 13. The instant heating boiler 13 operates according to the set program. If only 65-degree water is required, the instant heating boiler 13 does not heat, and the warm water flows out directly from the water outlet 10. If the water outlet 10 requires water with a temperature of 66-99 degrees, the instant heating boiler 13 operates at the required heating temperature to heat the 65-degree water again to the required temperature. This heating process is very fast, and the water that finally meets the standard still flows out from the water outlet 10.

[0036] The total power consumption of the whole machine is 3.5KW. When the machine is turned on, the steam boiler 4 consumes 2.5KW, the heat storage boiler 11 consumes 0.8KW, and the remaining power consumption is consumed by other components and the display screen. The period from the start-up to the normal use is divided into two stages; In the first stage, the steam boiler 4 heats to generate high-temperature steam and fills the heat storage boiler 11 with water (the water discharge of the heat storage boiler 11 can be controlled by pressing the corresponding buttons on the screen to confirm that the heat storage boiler 11 is full of water, and then the second heating tube 36 of 0.8KW is manually opened).

[0037] In the second stage, the pressure of the steam boiler 4 is maintained at 1.5 Bar, and the temperature of the heat storage boiler 11 is maintained at 65 degrees, which meets the requirements for preparing the cup.

[0038] When steam is used alone, the steam volume in the steam boiler 4 is maintained by the first heating tube 34 of 2.5 kW.

[0039] There are two situations when boiling water is used alone: 1. Cold water outlet separately: the water from the pressure reducing valve 6 is measured by the flow meter 24, flows through the two-position two-way solenoid valve 8 at the cold water end and directly flows out to the water outlet 10; 2. Separately discharge 65-99 degree water: The water from the pressure reducing valve 6 is measured by the flow meter 24, and is replaced with the warm water in the heat storage boiler 11 (the amount of water injected is equal to the amount of warm water replaced) through the heat storage two-position two-way solenoid valve 12 at the instant heating end. According to the final required boiling water temperature, the instant heating boiler 13 works, and the warm water is heated again and flows out from the water outlet 10. The instant heating boiler 13 takes up 3.3KW for heating. When the instant heating boiler 13 is working, the first heating tube 34 of 2.5KW and the second heating tube 36 of 0.8KW both stop working. At this time, if steam is needed, it can still be normally produced, and the volume of the steam boiler 4 retains a suitable amount of steam. When the 3.3KW instant boiler 13 stops heating, the 2.5KW first heating tube 34 and the 0.8KW second heating tube 36 both resume normal operation. Through staggered operation, the power consumption of the whole machine can be reduced to less than 3.5KW, while meeting the needs of producing both boiling water and steam at the same time.

[0040] The present invention uses only low power to maintain the temperature of the heat storage boiler 11. Only in the final heating, the high-power instant boiler 13 is used to cooperate, the energy consumption loss is small, and a certain cup output can be stably maintained; the temperature of the water is directly heated by the heating tube, which is understood as a constant temperature water, and its real-time temperature is the water temperature, and the temperature accuracy can reach ±1 degree (measured at the water outlet 10), rather than the existing technology such as high-temperature water plus low-temperature water. The water temperature fluctuates during the mixing process and is not easy to accurately measure, and the mixing requires a time process; through one in and one out, the amount of cold water injected is equal to the amount of hot water squeezed out, the flow rate is accurately controlled, and the form of the heat storage boiler 11 conforms to the physical phenomenon of hot water on the top and cold water on the bottom.

[0041] Beneficial effects of the present invention: 1. 3.5KW power consumption enables simultaneous production of steam and boiling water; 2. Boiling water can be produced at a constant temperature and quantity; 3. The flow meter 24 acts on the cold water end, and its accuracy is not affected by high temperature water (high temperature water will contain bubbles, thus affecting the flow accuracy), and is not affected by scale in the boiler (scale will be generated after heating water when the boiler is used for a long time and lacks maintenance); 4. Using the steam boiler 4 to preheat the water temperature effectively improves the ability of continuous water discharge and reduces the time for the instant boiler 13 to operate at full load for a long time; 5. The steam boiler 4 and the heat storage boiler 11 are made of the same material to achieve material versatility, and only different functions are realized by adding corresponding components and plugs.

[0042] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
