Description

Technical Field

[0001] This invention relates to the field of smart home appliance technology, and in particular to a water heater control method and water heater based on a backflow preventer and a dual-sensor turbine. Background Technology

[0002] In today's society, with the improvement of people's living standards, people have increasingly higher requirements for gas water heaters. The turbine flow sensor in the inlet pipe of a gas water heater, as a crucial component for sensing the inlet water flow, is essential for the normal operation of the water heater. Under normal circumstances, when water flows through the inlet pipe, the rotating component in the turbine flow sensor—the turbine—will automatically start rotating. The water flow sensor outside the turbine senses the frequency of the turbine's rotation and then starts the gas water heater. Another situation is due to problems with the home's plumbing; when the toilet or washing machine is turned on, water hammer can occur, causing the machine to automatically start when not in use.

[0003] Due to the complex water quality conditions across different regions of China, the turbine flow sensor in water heaters is prone to clogging after a period of use in some areas. This is primarily because the water flow passing through the turbine flow sensor contains particulate impurities. These impurities can easily jam the turbine, and the water flow speed cannot carry them away, causing the turbine to remain stuck. Consequently, the turbine cannot generate the water flow signal required by the gas water heater, preventing it from starting combustion properly and affecting normal user operation. Furthermore, once the turbine becomes clogged, it does not automatically reset. Manual tapping or alternating between high and low water flow rates is required to observe whether it can reset itself. If it cannot reset automatically, after-sales service is needed. When a user experiences automatic restarting, an external one-way valve needs to be installed. Summary of the Invention

[0070] Example 1

[0071] Please refer to Figure 1 This is a schematic diagram of a conventional turbine in its stationary state in existing technology. When a conventional turbine is not in operation, the lower end of the turbine rotor will fall into the limiting groove due to gravity. Please refer to... Figure 2 This is a structural diagram of a conventional turbine in operation. When a conventional turbine is working, the rotor rises due to the impact of water flow and the rotation of the rotor. A gap is formed between the lower end of the rotor and the limiting groove. Impurities can easily enter through this gap. When the turbine stops working, the rotor falls back, but the impurities in the gap have nowhere to be discharged and continue to accumulate in the gap, which may cause the rotor shaft to jam, preventing the turbine from working properly.

[0072] Please refer to Figure 3 This is a schematic diagram of the first structure with anti-reverse and dual induction turbines in this embodiment. Specifically, as shown... Figure 3As shown, the turbine with anti-reverse flow and dual sensing includes a turbine rotor 1, an anti-reverse plate assembly 2, a first sensor 3, and a second sensor 4. The anti-reverse plate assembly 2 rotatably covers the turbine's outlet to prevent water from flowing into the turbine from the outlet. The first sensor 3 senses the opening and closing of the anti-reverse plate assembly 2; the second sensor 4 senses the rotational speed of the turbine rotor. In this embodiment, when the turbine is stopped, water flows in from the turbine's outlet. The anti-reverse plate assembly 2 automatically closes under the impact of the water flow, covering the turbine's outlet and preventing water from flowing into the turbine from the outlet. Please refer to... Figure 4 This is a schematic diagram of the second structure in this embodiment, including a turbine rotor and a non-reverse turbine with dual induction turbines. Specifically, as shown... Figure 4 As shown, in this embodiment, when the turbine is in operation, water flows in from the turbine inlet. The check valve assembly 2 rotates and automatically opens under the impact of the water flow, allowing water to flow into the turbine from the outlet and out from the outlet. Furthermore, no gap is formed between the lower end of the rotor and the limiting groove, effectively preventing impurities from accumulating in the gap and potentially causing the rotor shaft to jam, thus enhancing the stability of the turbine.

[0073] In one optional embodiment, the check plate assembly includes a check plate 21, a rotating mechanism 22, and a sensing magnet 23; the rotating mechanism 22 is connected to one end of the check plate 21, and the sensing magnet 23 is disposed at the other end of the check plate; the rotating mechanism 22 is fixed to the edge of the outlet, and the check plate 21 is rotated by the rotating mechanism 22 to cover the outlet or move away from the outlet; the first sensor 3 senses the sensing magnet 23 when the check plate 21 moves away from the outlet to generate a first signal.

[0074] Please refer to Figure 5 This is a schematic diagram of the first process of the water heater control method based on a backflow preventer and dual-induction turbine in this embodiment. Specifically, as shown... Figure 5 As shown, the water heater control method includes:

[0075] S101, Acquire the first signal from the first sensor and the second signal from the second sensor;

[0076] S102, Generate water heater control signal based on the first signal and the second signal.

[0077] Please refer to Figure 6 This is a schematic diagram of the second process of the water heater control method based on a backflow preventer and dual-induction turbine in this embodiment. Specifically, as shown... Figure 6 As shown, step S102 may include:

[0078] S1021. When the first signal and the second signal are detected, a first water heater control signal is generated;

[0079] S1022. A second water heater control signal is generated when only the first signal or the second signal is detected.

[0080] S1023. When the first and second signals are not detected, a third water heater control signal is generated.

[0081] In this embodiment, the water heater control method further includes:

[0082] S1031. Control the water heater to work normally based on the first water heater control signal; specifically, in normal working mode, adjust according to PID (rapid matching adjustment).

[0083] S1032. Based on the second water heater control signal, control the water heater to enter the abnormal adjustment mode and report the fault of the sensor with no signal; specifically, in the abnormal adjustment mode, do not adjust according to PID, but adjust one degree at a time until the target stability is reached.

[0084] S1033, Control the water heater to stop working and report the fault based on the control signal of the third water heater.

[0085] Specifically, step S1032 may include:

[0086] When only the first signal is detected, the water heater is controlled to burn according to the historical data of the second sensor, and the temperature difference between the inlet and outlet water of the water heater is obtained within a preset time.

[0087] If the temperature difference between the inlet and outlet water exceeds the preset temperature threshold, the water heater will be controlled to work normally and a fault report will be sent to the second sensor that has no signal.

[0088] If the temperature difference between the inlet and outlet water is less than the preset temperature threshold, the water heater will stop working and report a fault to the first and second sensors.

[0089] When only the second signal is detected, the water heater is controlled to burn according to the second signal, and the temperature difference between the inlet and outlet water of the water heater is obtained within a preset time.

[0090] If the temperature difference between the inlet and outlet water exceeds the preset temperature threshold, the water heater will be controlled to work normally and a fault report will be sent to the first sensor that has no signal.

[0091] If the temperature difference between the inlet and outlet water is less than the preset temperature threshold, the water heater will stop working and a fault report will be sent to the first and second sensors.

[0092] The present invention provides a water heater control method based on a turbine with a check valve and dual sensors. The method involves installing a turbine with a check valve and dual sensors at the cold water inlet of the water heater. The check valve assembly of the turbine rotatably covers the turbine outlet to prevent water from flowing into the turbine from the outlet. A first sensor senses the opening and closing of the check valve assembly, and a second sensor senses the rotational speed of the turbine rotor.
