Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, and in particular to a fast-heating water boiler. Background Technology

[0002] A wood-fired water heater, also known as a wood-fired water tank, is a device that uses the heat generated by burning wood to heat water. It is widely used in remote rural areas and outdoor campsites. In these settings, where electricity and gas supplies may be unreliable or inconvenient, wood-fired water heaters become an ideal hot water solution. People can use these tanks to provide hot water to meet their daily needs.

[0003] The working principle of a firewood-heated water tank is to transfer the heat energy generated by burning firewood to the water in the tank, thereby heating the water. Its main components include a combustion chamber and a water tank located outside the combustion chamber. The combustion chamber is made of cast iron or steel, which has excellent high-temperature resistance and can transfer heat very well.

[0004] However, given that the principle of firewood-heated water tanks is to transfer heat released from burning wood to the water, the rate of temperature increase slows down as the water volume increases. In existing technologies, firewood-heated water tanks generally suffer from reduced heating speed and low heating efficiency when filled with large amounts of water, making it difficult to meet the demand for hot water. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a fast-heating water heater that optimizes the heat exchange path and improves the heat exchange efficiency, so that the water in the storage tank can be heated quickly to meet the needs of hot water use.

[0006] To solve the above-mentioned technical problems, this utility model proposes a rapid-heating water boiler, which adopts the following technical solution:

[0007] A rapid-heating water boiler includes a water injection tank, a water storage tank, a combustion chamber, and a flue gas system. The water injection tank is connected to the water storage tank. The combustion chamber is located inside the water storage tank. Both ends of the combustion chamber are fixedly connected to both ends of the water storage tank, and one end has a fuel inlet. The flue gas system is fixedly connected to the combustion chamber. The combustion chamber includes a heating chamber and a heating water pipe assembly. The heating water pipe assembly is inserted into the heating chamber and its two ends are connected to the water storage tank. The heating water pipe assembly is located at the end away from the fuel inlet. The heating water pipe assembly has at least two rows, and each row has multiple heating water pipes. Adjacent rows of heating water pipes are staggered.

[0008] By configuring the combustion chamber into two parts—a heating chamber and a heating water pipe assembly—the heat generated during heating can be directly and efficiently transferred to the water. Specifically, once the water tank is filled, the water fills the entire tank and the connected heating water pipe assembly. Then, firewood is added to the heating chamber through the fuel inlet and ignited. Because the heating water pipe assembly runs through the heating chamber, the burning firewood comes into close contact with the pipes. Furthermore, since both the heating chamber and the heating water pipe assembly are made of metal with good thermal conductivity, the heat released by the burning firewood efficiently heats the water in the pipe assembly. The staggered layout of the heating water pipes ensures that each pipe is unobstructed when heated, promoting full heat transfer and accelerating the heating process, thus improving heating efficiency. In addition, this layout also makes the heat distribution within the heating chamber more uniform, effectively reducing heat waste and localized overheating.

[0009] Furthermore, the exhaust system includes a flue, an exhaust pipe, and an exhaust fan. The flue is located in a water storage tank, with one end connected to the combustion chamber and the other end connected to the exhaust pipe. The exhaust pipe is located outside the water storage tank, and the exhaust fan is installed at the outlet of the exhaust pipe. In this design, the flue gas generated in the combustion chamber can be quickly discharged into the external environment through the flue and then through the exhaust pipe. The exhaust fan ensures smooth and efficient exhaust of the smoke, improving exhaust efficiency and preventing smoke from accumulating in the heating chamber, which would affect the heating effect. Moreover, since the flue is located in the water storage tank, the smoke passes through the water in the tank during exhaust, transferring the heat energy from the smoke to the water, achieving heat recovery and utilization, further improving heating efficiency.

[0010] Preferably, the flue includes two primary heating tubes and a secondary heating tube. The secondary heating tube is positioned above the primary heating tubes and between the two primary heating tubes. One end of the primary heating tube connects to the heating chamber, and the other end connects to the secondary heating tube. The other end of the secondary heating tube connects to the exhaust pipe. The structural design of the primary and secondary heating tubes allows the smoke to flow in a Z-shape. This arrangement ensures that the smoke comes into multiple contact with the tube wall during its flow, maximizing heat transfer to the water. The design of the secondary heating tube being positioned above the primary heating tubes and between the two primary heating tubes facilitates more even heat transfer to the surrounding water. This optimized heat transfer method not only improves the heating effect but also helps reduce heat loss and improve the overall thermal efficiency of the system.

[0011] Preferably, a steam-water separator is also included, with an installation pipe extending upwards from the upper end of the water storage tank, and the steam-water separator installed on top of the installation pipe. The main function of the steam-water separator is to separate water vapor from liquid water. In heating equipment such as water heaters, a large amount of steam is generated in the water due to the increase in water temperature. Without a steam-water separator, the generated steam cannot be discharged, which can lead to excessive pressure inside the water storage tank, posing a potential safety hazard.

[0012] Preferably, the steam-water separator includes a fixing component, a water inlet, and an air outlet pipe. The edge of the fixing component is fixedly connected to the mounting pipe. The water inlet is connected to the bottom of the fixing component, and the diameter of the water inlet is smaller than the diameter of the fixing component. Multiple water inlets are circumferentially arranged at the upper end of the water inlet, and the lower end of the water inlet is closed with multiple water outlets circumferentially arranged. The air outlet pipe is fixed to the fixing component, and its lower end extends to the middle of the inner side of the water inlet. Using this device, when the water heater is heating, water and steam enter the device through the water inlets. Under the action of gravity, the water flows out from the water outlets, while the steam is discharged to the outside through the air outlet pipe. This structure not only efficiently separates and discharges steam, improving separation efficiency, but also effectively prevents splashing caused by the overheating and expansion of water and steam.

[0013] Preferably, the water tank includes a tank body, a water inlet pipe, and a vent pipe. One end of the water inlet pipe and the vent pipe are connected to the tank body, and the other end is connected to the water storage tank and the installation pipe, respectively. Through the water inlet pipe, the water storage tank can receive a continuous and stable water supply, ensuring that the water storage tank maintains sufficient water volume at all times to meet usage needs. Simultaneously, since heat and water vapor exist inside the tank, the vent pipe guides the water vapor to the installation pipe and then discharges it through a vapor-water separator, thus helping to balance the pressure inside and outside the tank and preventing water flow obstruction due to excessive pressure.

[0014] Preferably, a flanged float valve is fixedly installed on one side of the tank, and a water inlet is located on the top of the tank. The introduction of the flanged float valve allows for effective and automatic adjustment of the water level inside the tank, eliminating the need for frequent manual intervention and improving the system's automation level. The water inlet design allows for manual water replenishment when the flanged float valve malfunctions, thus giving the boiler greater flexibility and adaptability.

[0015] Preferably, the exhaust pipe passes through the chamber and connects to the secondary heating pipe at the bottom. This design allows residual heat energy to be transferred to the water in the chamber before the smoke is exhausted. This heat recovery mechanism improves the overall energy efficiency of the system, optimizes the heat exchange path, reduces heat loss during heat transfer, and improves heat exchange efficiency.

[0016] Preferably, the system also includes a support assembly comprising a base frame and casters. The base frame is positioned below and supports the water tank, and the casters are positioned below the base frame. This design facilitates the movement of the bulky water boiler, improving its mobility.

[0017] Preferably, a drain valve is also included, which is fixedly installed on the side wall of the water storage tank. The introduction of the drain valve allows water in the water storage tank to be easily discharged, so that whether it is for regular cleaning of the water storage tank or for dealing with situations where the water storage tank needs to be emptied due to water quality issues, the water can be quickly discharged through the drain valve.

[0018] In summary, this rapid-heating water heater optimizes the heat exchange path and improves heat exchange efficiency, thereby enabling the water in the storage tank to be heated quickly and meeting the needs of hot water use. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] like Figure 1 and Figure 2 The rapid-heating water boiler shown includes a water injection tank 1, a water storage tank 2, a combustion chamber 3, and a flue gas system 4. The water injection tank 1 is connected to the water storage tank 2. The combustion chamber 3 is located inside the water storage tank 2. Both ends of the combustion chamber 3 are fixedly connected to both ends of the water storage tank 2, and one end has a fuel inlet 33. The flue gas system 4 is fixedly connected to the combustion chamber 3. The combustion chamber 3 includes a heating chamber 31 and a heating water pipe assembly 32. The heating water pipe assembly 32 is inserted in the heating chamber 31 and both ends are connected to the water storage tank 2. The heating water pipe assembly 32 is located at the end away from the fuel inlet 33. The heating water pipe assembly 32 has at least two rows, and each row has multiple heating water pipes. Adjacent rows of heating water pipes are staggered.

[0031] The combustion chamber 3 is structured as a two-part system consisting of a heating chamber 31 and a heating water pipe assembly 32, enabling direct and efficient transfer of heat generated during heating to the water. Specifically, when the water storage tank 2 is filled with water, the water fills the entire tank and the connected heating water pipe assembly 32. Then, firewood is added to the heating chamber 31 through the firewood inlet 33 and ignited. Because the heating water pipe assembly 32 runs through the heating chamber 31, the burning firewood comes into close contact with the assembly. Furthermore, since both the heating chamber 31 and the heating water pipe assembly 32 are made of metal with good thermal conductivity, the heat released by the burning firewood efficiently heats the water in the assembly. The staggered layout of the heating water pipes ensures that each pipe is unobstructed when heated, promoting full heat transfer and accelerating the water heating process, thus improving heating efficiency. In addition, this layout also makes the heat distribution within the heating chamber 31 more uniform, effectively reducing heat waste and localized overheating.

[0032] Furthermore, such as Figure 2As shown, the exhaust system 4 includes a flue 41, an exhaust pipe 42, and an exhaust fan 43. The flue 41 is located in the water storage tank 2, with one end connected to the combustion chamber 3 and the other end connected to the exhaust pipe 42. The exhaust pipe 42 is located outside the water storage tank 2, and the exhaust fan 43 is located at the outlet of the exhaust pipe 42. In this design, the flue gas generated in the combustion chamber 3 can be quickly discharged to the external environment through the flue 41 and then through the exhaust pipe 42. The exhaust fan 43 ensures that the smoke is discharged smoothly and efficiently, improving exhaust efficiency and preventing smoke from accumulating in the heating chamber 31, thus affecting the heating effect. Furthermore, since the flue 41 is located in the water storage tank 2, the smoke passes through the water in the water storage tank 2 during discharge, which transfers the heat energy in the smoke to the water, realizing heat recovery and utilization, further improving heating efficiency.

[0033] As a preferred option, such as Figure 2 As shown, the flue 41 includes two primary heating tubes 411 and a secondary heating tube 412. The secondary heating tube 412 is positioned above the primary heating tubes 411 and in the middle of the two primary heating tubes 411. One end of the primary heating tube 411 connects to the heating chamber 31, and the other end connects to the secondary heating tube 412. The other end of the secondary heating tube 412 connects to the exhaust pipe 42. The structural design of the primary heating tubes 411 and the secondary heating tube 412 allows the smoke to flow in a Z-shape. This layout ensures that the smoke comes into contact with the pipe wall multiple times during its flow, maximizing the heat transfer to the water. The design of the secondary heating tube 412 being positioned above the primary heating tubes 411 and in the middle of the two primary heating tubes 411 facilitates a more even distribution of heat energy to the surrounding water. This optimized heat transfer method not only improves the heating effect but also helps reduce heat loss and improve the overall thermal efficiency of the system.

[0034] As a preferred option, such as Figure 3 As shown, it also includes a steam-water separator 5. An installation pipe 21 extends upwards from the upper end of the water storage tank 2, and the steam-water separator 5 is installed on top of the installation pipe 21. The main function of the steam-water separator 5 is to separate water vapor from liquid water. In heating equipment such as water heaters, a large amount of steam is generated in the water due to the increase in water temperature. Without the steam-water separator 5, the generated steam cannot be discharged, leading to excessively high internal pressure in the water storage tank 2, which could pose a safety hazard.

[0035] As a preferred option, such as Figure 3As shown, the steam-water separator 5 includes a fixing member 51, a water inlet 52, and an air outlet pipe 53. The edge of the fixing member 51 is fixedly connected to the mounting pipe 21. The water inlet 52 is connected to the bottom of the fixing member 51, and the diameter of the water inlet 52 is smaller than the diameter of the fixing member 51. Multiple water inlets 521 are circumferentially arranged at the upper end of the water inlet 52, and multiple water outlets 522 are circumferentially arranged at the lower end of the water inlet 52. The air outlet pipe 53 is fixed to the fixing member 51, and its lower end extends to the middle of the inner side of the water inlet 52. Using this device, when the water heater is heating, water and steam enter the device from the water inlet 521. Under the action of gravity, the water flows out from the water outlet 522, while the steam is discharged to the outside through the air outlet pipe 53. This structure not only efficiently separates and discharges steam, improving separation efficiency, but also effectively prevents splashing caused by overheating and expansion of water and steam.

[0036] As a preferred option, such as Figure 1 and Figure 2 As shown, the water tank 1 includes a tank body 11, a water inlet pipe 12, and an exhaust pipe 13. One end of the water inlet pipe 12 and the exhaust pipe 13 are connected to the tank body 11, and the other end is connected to the water storage tank 2 and the installation pipe 21, respectively. Through the water inlet pipe 12, the water storage tank 2 can receive a continuous and stable water supply from the water tank 1. This design ensures that the water storage tank 1 can maintain sufficient water volume at all times to meet usage needs. At the same time, since there is also heat and water vapor inside the tank body 11, the exhaust pipe 13 can guide the water vapor to the installation pipe 21 and then discharge it through the steam-water separator 5, thereby helping to balance the pressure inside and outside the tank body and preventing water flow obstruction due to excessive pressure.

[0037] As a preferred option, such as Figure 1 As shown, a flanged float valve 111 is fixedly installed on one side of the tank 11, and a water inlet 112 is installed on the top of the tank 11. The introduction of the flanged float valve 111 allows for effective and automatic adjustment of the water level inside the tank 11, eliminating the need for frequent manual intervention and improving the system's automation level. The design of the water inlet 112 allows for manual water replenishment when the flanged float valve 111 fails to function properly, thus giving the water boiler greater flexibility and adaptability.

[0038] As a preferred option, such as Figure 1 and Figure 2 As shown, the exhaust pipe 42 passes through the housing 11 and its bottom is connected to the secondary heating pipe 412. This design allows residual heat energy to be transferred to the water in the housing 11 before the smoke is discharged. This heat recovery mechanism improves the energy utilization efficiency of the entire system, optimizes the heat exchange path, reduces heat loss during the heat transfer process, and improves heat exchange efficiency.

[0039] Preferably, the system also includes a support component 6, which comprises a base frame 61 and casters 62. The base frame 61 is positioned below and supports the water tank 2, and the casters 62 are positioned below the base frame 61. This design facilitates the movement of the bulky water boiler, improving its mobility.

[0040] As a preferred option, such as Figure 8 As shown, it also includes a drain valve 7, which is fixedly installed on the side wall of the water storage tank 2. The introduction of the drain valve 7 allows the water in the water storage tank 2 to be easily discharged. In this way, whether it is to perform regular cleaning of the water storage tank 2 or to deal with the situation where the water storage tank 2 needs to be emptied due to water quality problems, the water can be quickly discharged through the drain valve 7.

[0041] refer to Figure 1 , Figure 4 , Figure 5 as well as Figure 6 The water tank 1 can be placed in various ways to adapt to different working environments.

[0042] refer to Figure 7 The arrow indicates the direction of the hot smoke, which exchanges heat through layers of pipes to achieve efficient energy conversion.

[0043] In summary, this rapid-heating water heater optimizes the heat exchange path and improves heat exchange efficiency, thereby enabling the water in the storage tank to be heated quickly and meeting the needs of hot water use.
