Description

Technical Field

These types of gas water heaters have energy storage batteries installed inside their casings. These batteries store electrical energy and provide a stable power supply to the electrical components. When the installation environment of the gas water heater has low wind speeds or is windless for extended periods, the blade rotation slows down or stops completely, resulting in insufficient power generation to meet the water heater's electricity needs and affecting its normal operation.

It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] like Figure 1 As shown, this embodiment proposes a gas water heater, which can be an outdoor type or other type of water heater, without specific limitations. Specifically, the gas water heater includes a shell 1, electrical components 2, a burner, a heat exchanger, and a fume hood. The electrical components 2, burner, and heat exchanger are all installed inside the shell 1. The electrical components 2 include a water valve and a gas valve. The water valve is a water flow sensor assembly, and the gas valve is a gas proportional valve. The shell 1 also has a flue vent 11. Since an exhaust fan is installed inside the fume hood, the flue gas generated by the burner combustion passes through the fume hood and is discharged from the flue vent 11. Under the suction of the exhaust fan, the flue gas discharged from the flue vent 11 generates wind energy (i.e., kinetic energy). Since gas water heaters are existing technology, the structure and operation of components such as the electrical components 2, burner, heat exchanger, and fume hood inside the shell 1 will not be described in detail.

[0034] In existing gas water heaters, wind power generation components are installed to supply power to the internal electrical components, thereby reducing energy consumption. However, when the installation environment of the gas water heater has low wind speed or no wind for extended periods, the blade rotation slows down or stops completely, resulting in insufficient power generation to meet the electricity demand of the gas water heater and affecting its normal operation.

[0035] To solve the above problems, such as Figure 1 and Figure 2As shown, this embodiment proposes a gas water heater, which includes a casing 1, a power generation module, and an energy storage battery 4. The gas water heater includes a casing 1, a wind power generation component 3, and an energy storage battery 4. The wind power generation component 3 is disposed outside the casing 1 and includes a wind turbine and a generator. The blades 31 of the wind turbine are located in front of the exhaust port 11. The rotational coverage area of ​​the blades 31, along the axial direction of the wind turbine (front-back direction in the figure), projects onto the casing 1 and at least partially overlaps with the exhaust port 11. The energy storage battery 4 is disposed inside the casing 1 and is electrically connected to both the generator and the electrical component 2. The wind power generation component 3 is installed outside the casing 1 of the gas water heater. The blades 31 of the wind turbine are located in front of the exhaust port 11. The rotational coverage area of ​​the blades 31, along the axial direction of the wind turbine, projects onto the casing 1 and at least partially overlaps with the exhaust port 11, so that the flue gas discharged from the exhaust port 11 blows towards the blades 31 and drives the blades 31 to rotate and generate electricity, which is then supplied to the electrical component 2 through the energy storage battery 4. By fully utilizing the wind energy from the flue gas at the 11 exhaust outlets, the power generation efficiency of the wind power generation component 3 is improved, ensuring sufficient power generation even in low wind conditions or long periods without wind to meet the electricity demand of the gas water heater.

[0036] It is understood that in other embodiments, electrical component 6 may also include other electrical components with lower power requirements, such as common small LED displays, DC motors, DC fans and ignition needles, which can be electrically connected to the energy storage battery 4 and the wind power generation module 3 and can be set accordingly according to the actual needs of the water heater, which will not be elaborated here.

[0037] like Figure 2 and Figure 3 As shown, the wind power generation component 3 also includes a support 32 and a nacelle 33. The support 32 is located at the top of the outer shell 1. The nacelle 33 is located at the top of the support 32, and the generator is installed inside the nacelle 33. The generator's shaft is connected to the hub of the wind turbine, and the hub has multiple blades 31 spaced circumferentially. Specifically, the outer shell 1 includes a bottom shell and a top shell. The top shell is located on the front side of the bottom shell and is fastened to the bottom shell. The top of the top shell has a flue gas outlet 11. The support 32 can be fixedly installed at the top of the bottom shell by screws or welding. The nacelle 33 extends forward along the width direction of the outer shell 1 (the front-to-back direction in the figure) to the front of the top shell, so that the blades 31 are located in front of the flue gas outlet 11, thereby causing the flue gas at the flue gas outlet 11 to be blown towards the blades 31. In this embodiment, the hub has three blades 31 spaced circumferentially. In other embodiments, the hub may also have two or more blades 31 spaced circumferentially, which is not specifically limited here. Of course, the wind power generation component 3 also includes components such as the gearbox installed in the nacelle 33. Since the wind power generation component 3 is existing technology, the specific components and power generation principle of the wind power generation component 3 will not be described in detail.

[0038] It should be noted that, along the axial direction of the wind turbine, the exhaust port 11 is located within the projection of the outer casing 1 of the rotating coverage area of ​​the blade 31. This arrangement ensures that the exhaust gas discharged from the exhaust port 11 is entirely directed towards the blade 31, maximizing the wind energy of the exhaust gas itself and improving its utilization rate, thereby increasing the power generation efficiency of the wind turbine assembly 3.

[0039] like Figure 3 As shown, the distance H between the blade 31 and the exhaust port 11 is 20mm to 100mm. In this embodiment, the distance H is the distance between the blade 31 and the front side of the outer casing 1. The distance H can be 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, or 100mm, etc., so that the blade 31 and the exhaust port 11 have an appropriate distance to balance the full utilization of the wind energy of the flue gas at the exhaust port 11 and avoid interference with the outer casing 1. If the distance H is too small, the blade 31 may interfere with the components (such as the screen or knob) on the front surface of the outer casing 1 during rotation, affecting the normal use of the gas water heater; if the distance H is too large, the distance between the blade 31 and the exhaust port 11 is too far, reducing the utilization rate of the flue gas at the exhaust port 11.

[0040] like Figure 2 As shown, the gas water heater also includes a photovoltaic module 7, which is mounted on the outer casing 1 and electrically connected to the energy storage battery 4. The photovoltaic module 7 is installed on the sun-exposed outer surface of the casing 1. It generates electricity using solar energy and stores the energy in the energy storage battery 4, forming a wind-solar hybrid module with the wind power generation module 3. The photovoltaic module 7 provides supplemental power to the wind power generation module 3, meaning that the gas water heater can still generate electricity through the photovoltaic module 7 when wind power is insufficient, ensuring that the energy storage battery 4 has sufficient charge, thus improving power generation efficiency and output. Since the photovoltaic module 7 is existing technology, its working principle will not be described in detail.

[0041] Specifically, the photovoltaic module 7 is connected to the housing 1 by bolts. The bolts ensure the photovoltaic module 7 is positioned and installed on the housing 1, preventing the photovoltaic module 7 from slipping off or falling off the housing 1, thus improving the safety and stability of the photovoltaic module 7.

[0042] It should be noted that both the wind power generation module 3 and the photovoltaic module 7 mentioned above are low-voltage power generation modules. They are supplied with a safe 36V voltage via the energy storage battery 4, avoiding the risk of electric shock from the gas water heater and improving its safety. Generating electricity through wind and / or solar energy makes the gas water heater more energy-efficient and environmentally friendly.

[0043] like Figure 1As shown, a control module 5 is installed inside the outer casing 1. The control module 5 is electrically connected to the generator, the energy storage battery 4, and the electrical components 2. The control module 5 has a charging interface for charging the energy storage battery 4. An external power source (such as a low-voltage DC power supply) charges the energy storage battery 4 through the charging interface to replenish its energy in a timely manner. This prevents insufficient power generation during prolonged cloudy or windless weather, ensuring that the energy storage battery 4 always has sufficient power and avoiding any impact on the normal operation of the gas water heater. Since the control module 5 is a proprietary component of the gas water heater and is existing technology, its operation will not be described in detail.

[0044] In one embodiment, the gas water heater also includes an alarm. The control module 5 is electrically connected to the alarm, which is configured to trigger an audible and / or visual alarm when the power level of the energy storage battery 4 falls below a preset value. The alarm includes a battery capacity indicator module and a low-power alarm. The battery capacity indicator module can be in the form of indicator lights, graphics, etc., displaying the power level of the energy storage battery 4 through different colored indicator lights or different graphics to monitor the stored power level of the energy storage battery 4 in real time. During prolonged cloudy or windless conditions, when the power level of the energy storage battery 4 falls below a preset minimum value (which can be flexibly set according to usage), the low-power alarm will issue an audible and visual alarm, or only an audible and visual alarm, to remind the user to charge the battery in time and ensure the normal operation of the gas water heater.

[0045] like Figure 1 As shown, a baffle 6 is installed inside the outer casing 1. The baffle 6 and part of the side wall of the outer casing 1 form an energy storage box. The energy storage battery 4 is installed inside the energy storage box, and the electrical components 2 are located outside the energy storage box. By setting the baffle 6 to separate the energy storage battery 4 from the electrical components 2, it is possible to prevent the energy storage battery 4 from affecting the normal operation of the electrical components 2 (especially the gas valve) in the event of a malfunction, thus ensuring the safe and stable combustion of gas and improving the safety of the gas water heater. At the same time, the energy storage battery 4 is installed in a closed energy storage box, which separates it from the burner and heat exchanger. This allows for the independent installation of the energy storage battery 4, preventing it from being affected by the heat emitted by the burner and heat exchanger, which could cause excessive temperature rise. This ensures the normal charging and discharging function of the energy storage battery 4 and improves its safety.

[0046] It should be noted that the baffle 6 has a wire-passing hole, through which the wiring harness of the energy storage battery 4 passes and is electrically connected to the control module 5. After the wiring harness of the energy storage battery 4 passes through the wire-passing hole, the gap between the wiring harness and the wire-passing hole is sealed with sealant.

[0047] like Figure 1As shown, the side wall of the outer casing 1 has ventilation holes 12, which are connected to the inner cavity of the energy storage box. By providing ventilation holes 12, air from outside the outer casing 1 can enter and exit the inner cavity of the energy storage box, thereby achieving air cooling of the energy storage battery 4 and further reducing the temperature rise of the energy storage battery 4.

[0048] In one embodiment, the ventilation opening 12 is a downward-facing louvered opening along the height direction of the outer casing 1 (vertical direction in the figure). This design prevents external water (or rainwater) from entering the inner cavity of the energy storage box, further improving the safety of the energy storage battery 4.

[0049] In one embodiment, a dustproof mesh is installed inside the ventilation hole 12. This design prevents dust and other impurities from the outside of the outer casing 1 from entering the inner cavity of the energy storage box through the ventilation hole 12. The dustproof mesh effectively filters the air entering the inner cavity of the energy storage box, preventing the energy storage battery 4 from being contaminated or damaged by impurities, thus further improving the safety of the energy storage battery 4.

[0050] In this embodiment, the energy storage battery 4 has a capacity of 5 to 20 times the daily power consumption of the gas water heater. This ensures that the energy storage battery 4 can provide a stable power supply for a long time and avoids the problem of insufficient power generation in the energy storage battery 4 due to poor sunlight conditions (cloudy or rainy days) or low wind speeds. The daily power generation of the wind power generation module 3 or the photovoltaic module 7 is less than 0.3 times the capacity of the energy storage battery 4, which allows smaller wind turbines and smaller photovoltaic panels to meet the power generation needs and reduce costs.

[0051] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
