[0003] The purpose of this invention is to overcome the problems of the prior art and provide a fully premixed condensing volumetric hot water boiler that can realize both heating and hot water functions.

[0004] To achieve the above objectives, the present invention adopts the following solution:

[0005] A fully premixed condensing volumetric hot water boiler, comprising:

[0006] The casing contains a sealed chamber, within which a burner is housed. A water storage tank is located at the lower end of the sealed chamber, containing a heat exchange tube. The sealed chamber also houses a heating water pump and a three-way valve. A first pipe connects the burner's outlet to the three-way valve's first inlet. A second pipe connects the three-way valve's first outlet to a heating water supply line. A third pipe connects the three-way valve's second outlet to the heat exchange tube's inlet. A fourth pipe connects the heating water pump's outlet to the burner's inlet. A fifth pipe connects the heating water pump's first inlet to a return line. A sixth pipe connects the heating water pump's second inlet to the heat exchange tube's outlet. The water storage tank also has an outlet pipe for discharging water. The three-way valve has a valve core assembly that enables communication between the first inlet and the second pipe, or between the first inlet and the third pipe.

[0007] The three-way valve includes a valve body and a seat body disposed within the valve body. The seat body is provided with an inlet cavity corresponding to the first inlet. The seat body is provided with a first opening on the upper side of the inlet cavity that can connect the inlet cavity and the first outlet. The seat body is provided with a second opening on the lower side of the inlet cavity that can connect the inlet cavity and the second outlet.

[0008] The valve core assembly includes a mounting base connected to the valve body. The mounting base and the valve body are provided with a sliding rod that can slide relative to each other. The sliding rod is provided with a first sealing member and a second sealing member. The first sealing member is located on one side of a first opening, and the second sealing member is located on one side of a second opening. The mounting base is also connected to a driving member that can drive the sliding rod to slide. The second sealing member can slide with the sliding rod to close the first opening or leave the first opening, and the second sealing member can slide with the sliding rod to leave the second opening or close the second opening.

[0009] The first sealing member is slidably connected to the sliding rod, and an elastic member capable of pushing the first sealing member and resetting it is provided between the first sealing member and the seat.

[0010] The sealed chamber is provided with a first mounting plate and a second mounting plate, and an installation cavity is formed between the first mounting plate and the second mounting plate at an interval. The second mounting plate is located on the top of the water storage tank and is provided with a plurality of first positioning holes.

[0011] The heating water pump and three-way valve are mounted on the first mounting plate. The first mounting plate is also equipped with an air intake pump, which is connected to the burner. The first mounting plate is also equipped with multiple second empty holes.

[0012] The heat exchange tube is a coil installed in the water storage tank. The third pipeline is provided between the inlet of the coil and the second outlet of the three-way valve. The sixth pipeline is provided between the outlet of the coil and the second inlet of the heating water pump. The third and sixth pipelines are installed in the installation cavity.

[0013] The outer casing is also connected to a water pump that communicates with the water outlet pipe. Both the water pump and the water outlet pipe are located inside the mounting cavity. The water storage tank is also equipped with a water inlet pipe.

[0016] Compared with existing technologies, this utility model has the following advantages: In use, the water is heated by a burner. The heated water then enters the first pipeline through the outlet, flows into a three-way valve, exits through the first outlet of the three-way valve into the second pipeline, and circulates through the second pipeline into the heating system. The circulated water then enters the fifth pipeline, enters the heating water pump, and then enters the fourth pipeline through the first inlet of the heating water pump. Finally, it returns to the burner for reheating. During this process, the valve core assembly allows the first inlet to be connected to the third pipeline, and when… When the first inlet is connected to the third pipe, the first inlet is closed to the second pipe. So when hot water enters the three-way valve, it enters the heat exchange tube through the second outlet. The heat exchange tube heats the water in the storage tank. At this time, the heat exchange tube heats the water in the storage tank through heat exchange. The water in the heat exchange tube flows out to the second inlet of the heating water pump, then enters the fourth pipe through the first inlet, and finally returns to the burner for reheating. Because it has dual channels, it can realize the application of heating and hot water, and has a wider range of applications. Moreover, due to the setting of the storage tank, it can realize water storage and preheating, so it is more convenient to use. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to embodiments:

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0023] like Figures 1 to 4As shown, a fully premixed condensing volumetric hot water boiler includes: an outer shell 1, a sealed chamber 11 inside the outer shell 1, a burner 21 inside the sealed chamber 11, a water storage tank 22 at the lower end of the sealed chamber 11, a heat exchange tube 23 inside the water storage tank 22, a heating water pump 24 and a three-way valve 25 inside the sealed chamber 11, a first pipeline 31 connecting the outlet of the burner 21 to the first inlet 251 of the three-way valve 25, a second pipeline 32 connecting the first outlet 252 of the three-way valve 25 to supply heating water, and a second outlet 253 of the three-way valve 25 to the heat exchange tube. A third pipe 33 is provided between the inlets of the heating water pump 24 and the inlet of the burner 21. A fourth pipe 34 is provided between the outlet of the heating water pump 24 and the inlet of the burner 21. A fifth pipe 35 is connected to the first inlet 241 of the heating water pump 24 to allow the heating water to flow back. A sixth pipe 36 is provided between the second inlet 242 of the heating water pump 24 and the outlet of the heat exchange pipe 23. An outlet pipe 37 is also provided on the water storage tank 22 to allow water to flow out. A valve core assembly 4 is provided on the three-way valve 25 to enable the first inlet 251 to connect with the second pipe 32 or to enable the first inlet 251 to connect with the third pipe 33.

[0024] In use, this invention heats water via burner 21. The heated water then flows through the outlet into the first pipe 31, from where it flows into the three-way valve 25. From the first outlet 252 of the three-way valve 25, it flows into the second pipe 32, and from the second pipe 32, it circulates in the heating system. The circulated water then enters the fifth pipe 35, from which it enters the heating water pump 24. From the first inlet 241 of the heating water pump 24, it enters the fourth pipe 34, and finally returns to the burner 21 for reheating. During this process, the valve core assembly 4 allows the first inlet 251 to be connected to the third pipe 33. When the circuit 33 is open, the first inlet 251 and the second pipe 32 are closed. So when hot water enters the three-way valve 25, it enters the heat exchange tube 23 through the second outlet 253. The heat exchange tube 23 heats the water in the storage tank 22. At this time, the heat exchange tube 23 heats the water in the storage tank 22 through heat exchange. The water in the heat exchange tube 23 flows out to the second inlet 242 of the heating water pump 24, and then enters the fourth pipe 34 through the first inlet 241. Finally, it returns to the burner 21 for reheating. Because it has dual channels, it can realize the application of heating and hot water, and has a wider range of applications. Moreover, due to the setting of the storage tank 22, it can realize water storage and preheating, so it is more convenient to use.

[0025] The three-way valve 25 includes a valve body 254 and a seat 255 disposed within the valve body 254. The seat 255 has an inlet cavity 2551 corresponding to the first inlet 251. The seat 255 has a first opening 2552 on its upper side, connecting the inlet cavity 2551 to the first outlet 252. The seat 255 also has a second opening 2553 on its lower side, connecting the inlet cavity 2551 to the second outlet 253. By providing the inlet cavity 2551 on the seat 255 corresponding to the first inlet 251, and the first and second openings 2552 and 2553 on its upper and lower sides, precise water flow distribution is achieved. Water can be directed to either the first outlet 252 or the second outlet 253 as needed. The valve has a compact structure, small overall size, and is easy to install.

[0026] The valve core assembly 4 includes a mounting base 41 connected to the valve body 254. The mounting base 41 and the seat body 255 are provided with a sliding rod 42 that can slide relative to each other. The sliding rod 42 is provided with a first sealing member 43 and a second sealing member 44. The first sealing member 43 is located on one side of the first opening 2552, and the second sealing member 44 is located on one side of the second opening 2553. The mounting base 41 is also connected to a driving member 45 that can drive the sliding rod 42 to slide. The second sealing member 44 can slide with the sliding rod 42 to close the first opening 2552 or leave the first opening 2552. The second sealing member 44 can slide with the sliding rod 42 to leave the second opening 2553 or close the second opening 2553.

[0027] Water flows into the valve body 254 of the three-way valve from the first inlet 251, and then into the inlet chamber 2551 on the seat 255. The driving member 45 drives the sliding rod 42 to slide, causing the second sealing member 44 to leave the first opening 2552. At the same time, when the first sealing member 43 closes the second opening 2553, the water flows from the inlet chamber 2551 through the first opening 2552 to the first outlet 252, and then flows out from the first outlet 252 into the fifth pipeline 35. When the driving member 45 drives the sliding rod 42 to slide, causing the second sealing member 44 to close the first opening 2552, and at the same time, when the first sealing member 43 leaves the second opening 2553, the water flows from the inlet chamber 2551 through the second opening 2553 to the second outlet 253, and then flows out from the second outlet 253 into the heat exchange tube 23. By sliding the sliding rod 42 in the valve core assembly 4 and cooperating with the first sealing member 43 and the second sealing member 44, the water flow can be flexibly switched between the first outlet 252 and the second outlet 253, thus meeting different water flow distribution requirements.

[0028] The first sealing member 43 is slidably connected to the sliding rod 42. An elastic element 46 is provided between the first sealing member 43 and the seat 255, capable of pushing the first sealing member 43 to its original position. When the sliding rod 42 moves the first sealing member 43 to close the second opening 2553, the elastic element 46 between the first sealing member 43 and the seat 255 is compressed. When the sliding rod 42 moves the first sealing member 43 away from the second opening 2553, the elastic element 46 returns to its original state, allowing water to flow in through the gap between the first sealing member 43 and the second opening 2553.

[0029] The sealed chamber 11 is equipped with a first mounting plate 12 and a second mounting plate 13, with a mounting cavity 14 formed between the first mounting plate 12 and the second mounting plate 13 at an interval. The second mounting plate 13 is located on the top of the water storage tank 22 and has multiple first positioning holes 131. This structural design not only makes reasonable use of the space within the sealed chamber 11 and enhances the stability of the overall structure, but also provides precise installation positions for related components through the first positioning holes 131, facilitating quick and accurate component installation and connection.

[0030] The heating water pump 24 and the three-way valve 25 are mounted on the first mounting plate 12. The first mounting plate 12 is also equipped with an air intake pump 5, which is connected to the burner 21. The first mounting plate 12 is provided with a plurality of second empty holes 121.

[0031] This design enables the integrated installation of multiple key components. The centralized layout of the first mounting plate 12 allows for a more compact installation of the heating water pump 24, three-way valve 25, and air pump 5, reducing their footprint. Furthermore, the centralized installation method of the first mounting plate 12 facilitates management and maintenance, reduces the complexity of connections between components, and lowers installation costs.

[0032] The heat exchange tube 23 is a coil installed inside the water storage tank 22. A third pipe 33 is provided between the inlet of the coil and the second outlet 253 of the three-way valve 25. A sixth pipe 36 is provided between the outlet of the coil and the second inlet 242 of the heating water pump 24. Both the third pipe 33 and the sixth pipe 36 are located within the installation cavity 14. This arrangement not only makes the pipe layout neater and more rational, facilitating installation and maintenance, but also effectively protects the pipes from external environmental influences, extending their service life.

[0033] The outer casing 1 is also connected to a water pump 6 that communicates with the water outlet pipe 37. Both the water pump 6 and the water outlet pipe 37 are located within the mounting cavity 14. The water storage tank 22 is also equipped with a water inlet pipe 38. The mounting cavity 14 provides a stable installation environment for the water pump 6 and the water outlet pipe 37, reducing external interference. The water pump 6 can assist in pressurization, facilitating the flow of hot water.

[0034] An expansion tank 7 is also installed inside the sealed chamber 11. The expansion tank 7 is connected to the heating water pump 24 and the burner 21 by a pipeline. The expansion tank 7 can effectively compensate for changes in the water volume in the system, provide space for the expanding water, prevent the system pressure from being too high and damaging the components, and replenish water back into the system when the water temperature drops and the volume shrinks, maintaining the normal operation of the system and ensuring stable system pressure.

[0035] The water storage tank 22 is also equipped with a temperature sensor, which is electrically connected to the drive component 45 of the valve core assembly 4. Furthermore, this invention allows for the preset use of a temperature, such as 50℃, 55℃, 60℃, and 65℃. When the temperature sensor in the water storage tank 22 detects a 5℃ difference between the water temperature and the preset temperature, it activates the drive component 45 of the valve core assembly 4, causing the drive component 45 to switch the water channel and heat the water to the preset temperature via the heat exchange tube 23. This ensures a constant water temperature for the user, making it more convenient to use.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
