Abstract
Description
Technical Field
[0001] This utility model relates to the field of water heater technology, and in particular to a dual-core water heater. Background Technology
[0002] A water heater is a device that uses physical or chemical principles to raise the temperature of cold water to hot water within a certain period of time. According to different principles, it can be divided into electric water heaters, gas water heaters, solar water heaters, magnetic water heaters, air source water heaters, and heating water heaters, etc.
[0003] For example, a gas water heater, also known as a gas water boiler, is a gas appliance that uses gas as fuel and heats water by burning it, transferring heat to cold water flowing through a heat exchanger to produce hot water.
[0004] The water heaters in the relevant technologies only have one core, which includes a heat exchanger. When cold water passes through the heat exchanger, it is converted into hot water and discharged. When the core malfunctions, the water heater cannot be used, which has certain limitations. Utility Model Content
[0005] To overcome at least one of the defects of the prior art, this utility model provides a dual-core water heater, which is equipped with a first core and a second core. When one core fails, the other core can still be used, thus facilitating user operation. Moreover, since a water control valve is provided, when one core fails and the other core is operating normally, the valve core corresponding to the failed core can be closed to prevent the water pipe corresponding to the failed core from continuing to flow into the water control valve, thereby avoiding affecting the outlet water temperature of the water pipe corresponding to the normally operating core.
[0006] The technical solution adopted by this utility model to solve its problem is:
[0007] A dual-core water heater, comprising:
[0008] First movement;

[0020] When the first coil is de-energized, under the action of the first elastic element and the first fixed iron core, the first moving magnetic core moves away from and opens the first water inlet of the water control valve;
[0021] When the first coil is energized, under the action of the first elastic element and the first fixed iron core, the first moving magnetic core approaches and closes the first water inlet of the water control valve.

[0043] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.
[0044] See Figures 1 to 3 This utility model discloses a dual-core water heater, comprising: a first core 10; a second core 20; a water system 30, the water system 30 including a first water pipe 301 and a second water pipe 302, the first water pipe 301 exchanging heat with the first core 10, and the second water pipe 302 exchanging heat with the second core 20; a water control valve 40, the water control valve 40 including a first valve core 401, a second valve core 402, and a valve body 403, the valve body 403 being provided with a first inlet 404, a second inlet 405, and a main outlet 406 that are interconnected, the first valve core 401 being located at the first inlet 404 of the water control valve 40, and the second valve core 402 being located at the second inlet 405 of the water control valve 40; the outlet of the first water pipe 301 being connected to the first inlet 404 of the water control valve 40, and the outlet of the second water pipe 302 being connected to the second inlet 405 of the water control valve 40.
[0045] This utility model is equipped with a first mechanism 10 and a second mechanism 20. When one mechanism fails, the other mechanism can still be used, which makes it convenient for users. Moreover, since a water control valve 40 is provided, when one mechanism fails and the other mechanism is operating normally, the valve corresponding to the failed mechanism can be closed to prevent the water pipe corresponding to the failed mechanism from continuing to flow into the water control valve 40, thereby avoiding affecting the water outlet temperature of the water pipe corresponding to the normally operating mechanism.
[0046] It should be noted that the main outlet 406 of the water control valve 40 is connected to the main outlet pipe 303.
[0047] In this embodiment of the invention, the first core 10 includes a first heat exchanger, and the second core 20 includes a second heat exchanger.
[0048] For example, the first heat exchanger can be a gas burner or an electric heating element, and the second heat exchanger can be a gas burner or an electric heating element; after the gas burner is ignited, it generates heat energy, and the first water pipe 301 or the second water pipe 302 can be heated when it is close to the gas burner, thereby heating the cold water in the first water pipe 301 or the second water pipe 302 into hot water; after the electric heating element is powered on, it generates heat energy, and the first water pipe 301 or the second water pipe 302 can be heated when it is close to the gas burner, thereby heating the cold water in the first water pipe 301 or the second water pipe 302 into hot water.
[0049] In this embodiment of the utility model, a first water flow sensor 50 is provided on the first water pipe 301, a first inlet water temperature sensor 60 is provided at the inlet of the first water pipe 301, and a first outlet water temperature sensor 70 is provided at the outlet of the first water pipe 301; a first heat exchanger is provided near the middle of the first water pipe 301.
[0050] For example, see Figure 1 The first water flow sensor 50 is installed near the inlet of the first water pipe 301. The first water flow sensor 50 is used to detect the inlet water flow of the first water pipe 301. The first inlet water temperature sensor 60 is used to detect the inlet water temperature of the first water pipe 301. The first outlet water temperature sensor 70 is used to detect the outlet water temperature of the first water pipe 301. The middle part of the first water pipe 301 is coiled outside the first heat exchanger.
[0051] It should be noted that the first water flow sensor 50 can be a direct replacement for an existing water flow sensor, such as a flow meter, and the first inlet water temperature sensor 60 and the first outlet water temperature sensor 70 can both be direct replacements for existing temperature sensors.
[0052] In this embodiment of the utility model, a second water flow sensor 80 is provided on the second water pipe 302, a second inlet water temperature sensor 90 is provided at the inlet of the second water pipe 302, and a second outlet water temperature sensor 100 is provided at the outlet of the second water pipe 302; the second heat exchanger is located near the middle of the second water pipe 302.
[0053] For example, see Figure 1The second water flow sensor 80 is installed near the inlet of the second water pipe 302. The second water flow sensor 80 is used to detect the inlet flow rate of the second water pipe 302. The second inlet water temperature sensor 90 is used to detect the inlet water temperature of the second water pipe 302. The second outlet water temperature sensor 100 is used to detect the outlet water temperature of the first water pipe 301. The middle part of the second water pipe 302 is coiled outside the second heat exchanger.
[0054] It should be noted that the second water flow sensor 80 can directly use existing water flow sensors, such as flow meters, and the second inlet water temperature sensor 90 and the second outlet water temperature sensor 100 can both directly use existing temperature sensors.
[0055] In this embodiment of the utility model, the dual-core water heater also includes a controller 110, and the first water flow sensor 50, the first inlet water temperature sensor 60, the first outlet water temperature sensor 70, the second water flow sensor 80, the second inlet water temperature sensor 90, and the second outlet water temperature sensor 100 are all electrically connected to the controller 110 or connected via electrical signals.
[0056] Thus, the first water flow sensor 50, the first inlet water temperature sensor 60, the first outlet water temperature sensor 70, the second water flow sensor 80, the second inlet water temperature sensor 90, and the second outlet water temperature sensor 100 can all transmit their respective data to the controller 110 for analysis. Of course, the data transmitted by the first water flow sensor 50, the first inlet water temperature sensor 60, the first outlet water temperature sensor 70, the second water flow sensor 80, the second inlet water temperature sensor 90, and the second outlet water temperature sensor 100 can also be read and analyzed manually.
[0057] In this embodiment of the present invention, the first valve core 401 includes a first fixed iron core 4011, a first moving magnetic core 4012, a first elastic element 4013, and a first coil 4014. The first coil 4014 is wound around the outside of the first fixed iron core 4011. The first moving magnetic core 4012 is movably disposed between the first fixed iron core 4011 and the first water inlet 404 of the water control valve 40. The first elastic element 4013 is sleeved on the outside of the first moving magnetic core 4012. When the first coil 4014 is de-energized, under the action of the first elastic element 4013 and the first fixed iron core 4011, the first moving magnetic core 4012 moves away from and opens the first water inlet 404 of the water control valve 40. When the first coil 4014 is energized, under the action of the first elastic element 4013 and the first fixed iron core 4011, the first moving magnetic core 4012 approaches and closes the first water inlet 404 of the water control valve 40.
[0058] For example, see Figure 2 as well as Figure 3The first valve core 401 is a normally open valve core, the first fixed iron core 4011 is made of metallic iron; the first moving magnetic core 4012 is a permanent magnet, such as neodymium iron boron, ferrite permanent magnet material, etc.; the first elastic element 4013 is a spring; the first fixed iron core 4011 is located above the first moving magnetic core 4012, and the first water inlet 404 of the water control valve 40 is located below the first moving magnetic core 4012.
[0059] In order to make the structure compact and facilitate the connection between the first elastic element 4013 and the first moving magnetic core 4012, the first moving magnetic core 4012 is "T" or "I" shaped. The first moving magnetic core 4012 can be integrally formed, or it can be made in parts and then connected into one piece by welding, bonding, snap-fitting or other methods.
[0060] When the first coil 4014 is de-energized, the elastic force of the first elastic element 4013 and the magnetic attraction between the first fixed iron core 4011 and the first moving magnetic core 4012 overcome the gravity of the first moving magnetic core 4012, causing the first moving magnetic core 4012 to move closer to the first fixed iron core 4011, that is, the first moving magnetic core 4012 moves upward, thereby opening the first water inlet 404 of the water control valve 40, and the water in the first water pipe 301 can flow into the water control valve 40.
[0061] When the first coil 4014 is energized, the first fixed iron core 4011 is magnetized and becomes magnetic. By controlling the direction of the current in the first coil 4014, the magnetized first fixed iron core 4011 and the first moving magnetic core 4012 repel each other. For example, the N pole of the magnetized first fixed iron core 4011 corresponds to the N pole of the first moving magnetic core 4012, or the S pole of the magnetized first fixed iron core 4011 corresponds to the S pole of the first moving magnetic core 4012. The repulsive force between the first fixed iron core 4011 and the first moving magnetic core 4012, as well as the gravity of the first moving magnetic core 4012, overcomes the elastic force of the first elastic member 4013, thereby pushing the first moving magnetic core 4012 to move downward. The first elastic member 4013 is compressed, and the first moving magnetic core 4012 closes the first water inlet 404 of the water control valve 40, preventing water in the first water pipe 301 from flowing into the water control valve 40.
[0062] To improve sealing, a first sealing ring 4015 is provided at the lower end of the first moving magnetic core 4012.
[0063] In this embodiment of the present invention, the second valve core 402 includes a second fixed iron core 4021, a second moving magnetic core 4022, a second elastic element 4023, and a second coil 4024. The second coil 4024 is wound around the outside of the second fixed iron core 4021. The second moving magnetic core 4022 is movably disposed between the second fixed iron core 4021 and the second water inlet 405 of the water control valve 40. The second elastic element 4023 is sleeved on the outside of the second moving magnetic core 4022. When the second coil 4024 is de-energized, under the action of the second elastic element 4023 and the second fixed iron core 4021, the second moving magnetic core 4022 moves away from and opens the second water inlet 405 of the water control valve 40. When the second coil 4024 is energized, under the action of the second elastic element 4023 and the second fixed iron core 4021, the second moving magnetic core 4022 approaches and closes the second water inlet 405 of the water control valve 40.
[0064] For example, see Figure 2 as well as Figure 3 The second valve core 402 is a normally open valve core, the second fixed iron core 4021 is made of metallic iron; the second moving magnetic core 4022 is a permanent magnet, such as neodymium iron boron, ferrite permanent magnet material, etc.; the second elastic element 4023 is a spring; the second fixed iron core 4021 is located above the second moving magnetic core 4022, and the second water inlet 405 of the water control valve 40 is located below the second moving magnetic core 4022.
[0065] In order to make the structure compact and facilitate the connection between the second elastic element 4023 and the second moving magnetic core 4022, the second moving magnetic core 4022 is "T" or "I" shaped. The second moving magnetic core 4022 can be integrally formed, or it can be made in parts and then connected into one piece by welding, bonding, snap-fitting or other methods.
[0066] When the second coil 4024 is de-energized, the elastic force of the second elastic element 4023 and the magnetic attraction between the second fixed iron core 4021 and the second moving magnetic core 4022 overcome the gravity of the second moving magnetic core 4022, causing the second moving magnetic core 4022 to move closer to the second fixed iron core 4021, that is, the second moving magnetic core 4022 moves upward, thereby opening the second water inlet 405 of the water control valve 40, and the water in the second water pipe 302 can flow into the water control valve 40.
[0067] By controlling the direction of the current in the second coil 4024, the second fixed iron core 4021 is magnetized and then repelled by the second moving magnetic core 4022. For example, the N pole of the second fixed iron core 4021 after being magnetized corresponds to the N pole of the second moving magnetic core 4022, or the S pole of the second fixed iron core 4021 after being magnetized corresponds to the S pole of the second moving magnetic core 4022. The repulsive force between the second fixed iron core 4021 and the second moving magnetic core 4022, as well as the gravity of the second moving magnetic core 4022, overcomes the elastic force of the second elastic member 4023, thus pushing the second moving magnetic core 4022 downward. The second elastic member 4023 is compressed, and the second moving magnetic core 4022 closes the second water inlet 405 of the water control valve 40, preventing water in the second water pipe 302 from flowing into the water control valve 40.
[0068] To improve sealing, a second sealing ring 4025 is provided at the lower end of the second moving magnetic core 4022.
[0069] It should be noted that, for ease of control, the energizing switches of the first coil 4014 and the second coil 4024 are electrically connected to the controller 110 or connected via electrical signals.
[0070] In this embodiment of the utility model, the inlet of the first water pipe 301 and the inlet of the second water pipe 302 are connected to the main water inlet pipe 304 through a three-way valve.
[0071] In this embodiment of the utility model, both the first core 10 and the second core 20 are gas cores; the dual core water heater also includes a first air inlet pipe 120 and a second air inlet pipe 130, the first air inlet pipe 120 is connected to the first core 10, and the second air inlet pipe 130 is connected to the second core 20.
[0072] For example, see Figure 1 To simplify the structure, the air inlet of the first air inlet pipe 120 and the air inlet of the second air inlet pipe 130 are connected to the main air inlet pipe 140 through another three-way valve.
[0073] It should be noted that when both the first core 10 and the second core 20 are gas cores, the dual-core water heater is a dual-core gas water heater, which also includes a first fan 150 and a second fan 160.
[0074] For example, see Figure 4 , Figure 4 This is a schematic diagram illustrating the specific workflow of the dual-core water heater when it is a dual-core gas water heater.
[0075] In this embodiment of the utility model, the dual-core water heater also includes a housing 170, and the first core 10 and the second core 20 are both disposed in the inner cavity of the housing 170.
[0076] Since both the first movement 10 and the second movement 20 are located inside the housing 170, the housing 170 can protect the first movement 10 and the second movement 20.
[0077] It should be noted that, for reference Figure 4 The following explanation uses this dual-core gas water heater as an example to illustrate its specific working process.
[0078] (1) After the dual-core water heater is started in the hot standby state, the first water flow sensor 50 is activated to detect the current water flow of the first water pipe 301, and the second water flow sensor 80 is activated to detect the current water flow of the second water pipe 302.
[0079] When the first water flow sensor 50 detects that the current water flow I1 is greater than or equal to the start water flow I... 启 Furthermore, the second water flow sensor 80 detects that the current water flow I2 is greater than or equal to the starting water flow I. 启 The water flow rate of the first water pipe 301 meets the start-up flow rate of the first mechanism 10, and the water flow rate of the second water pipe 302 meets the start-up flow rate of the second mechanism 20.
[0080] (2) Turn on the first fan 150 to discharge the exhaust gas before the first core 10 is ignited, turn on the second fan 160 to discharge the exhaust gas before the second core 20 is ignited, the first core 10 is ignited and burned, the second core 20 is ignited and burned, and the dual core water heater enters normal operation and combustion.
[0081] If no fault occurs during the operation of the first mechanism 10 and the second mechanism 20, the first valve core 401 and the second valve core 402 of the water control valve 40 are both in a de-energized state. Both the first valve core 401 and the second valve core 402 are open, the first inlet 404 of the water control valve 40 is open, and the second inlet 405 of the water control valve 40 is open. The hot water from the first water pipe 301, after heat exchange with the first mechanism 10, flows into the first inlet 404 of the water control valve 40 through its outlet. The hot water from the second water pipe 302, after heat exchange with the second mechanism 20, flows into the second inlet 405 of the water control valve 40 through its outlet. In this way, the hot water flowing out of the first water pipe 301 and the hot water flowing out of the second water pipe 302 merge in the water control valve 40 and then flow out from the main outlet 406 of the water control valve 40.
[0082] (3) When the first water flow sensor 50 cannot detect water flow or detects that the current water flow I1 is less than the starting water flow I 启 And / or the outlet water temperature T of the first water pipe 301 出1 ≈Inlet water temperature T 进1 If the first mechanism 10 reports a fault, the first valve core 401 is energized to close, and the first valve core 401 disconnects the water path of the first water pipe 301.
[0083] (4) When the second water flow sensor 80 cannot detect the water flow or detects that the current water flow I2 is less than the starting water flow I 启 and / or the outlet water temperature T of the second water pipe 302 出2 ≈Inlet water temperature T 进2 If the second mechanism 20 reports a fault, the second valve core 402 is energized to close the first valve core 401, and the second valve core 402 disconnects the water path of the second water pipe 302.
[0084] Based on the above structure, when one of the core mechanisms malfunctions while the other is operating normally, the valve core corresponding to the malfunctioning core can be closed to prevent the water pipe corresponding to the malfunctioning core from continuing to flow into the water control valve 40. This can avoid affecting the outlet water temperature of the water pipe corresponding to the normally operating core, so that even if one core mechanism malfunctions, the other core mechanism can still provide hot water normally.
[0085] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
