Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to an ozone water heater and its control method, as well as a computer-readable storage medium. Background Technology

[0002] As people's living standards improve, their demands for comfort in their home life are also increasing. Water heaters, as frequently used household appliances, can heat water from room temperature or low temperature to the user's desired temperature in a short time. However, existing water heaters typically only provide regular hot water, offering relatively limited functionality. Furthermore, during use, water heaters sometimes fail to produce water properly due to low pressure differentials, resulting in a poor user experience. Summary of the Invention

[0003] The purpose of this invention is to provide an ozone water heater and its control method, as well as a computer-readable storage medium, in order to solve the problems of water heaters having limited functionality and unreliable operation.

[0004] To achieve the above objectives, the technical solutions adopted in the embodiments of the present invention are as follows:

[0005] An ozone water heater includes an inlet pipe, a first gas supply pipe, an outlet pipe, a heating device, a gas-liquid mixing device, an ozone generating device, a first gas pump, a first control valve, a second control valve, a water flow detection device, and a control device.

[0006] The water inlet pipe is connected to the heating device; a water flow detection device is installed on the water inlet pipe to detect the water flow in the water inlet pipe;

[0007] The water outlet pipeline includes a first pipeline, a second pipeline, and a third pipeline. The inlet ends of the first and second pipelines are connected to the heating device, and the outlet ends of the first and second pipelines are connected to the inlet end of the third pipeline. A first control valve is located on the first pipeline, and a second control valve is located on the second pipeline.

[0008] The first gas supply pipeline is connected to the first pipeline. The ozone generator and the first gas pump are located on the first gas supply pipeline. The ozone generator is used to generate ozone gas, and the first gas pump is used to pressurize and drive the ozone gas to the gas-liquid mixing device.

[0009] The gas-liquid mixing device is installed on the first or third pipeline and is used to mix the input ozone gas with water to produce ozone microbubble water.

[0010] The control device is connected to the first air pump, the first control valve, the second control valve, the ozone generator, and the heating device to control the working status of the ozone generator, the heating device, the first air pump, the first control valve, and the second control valve.

[0011] In one possible implementation, the ozone water heater further includes a second gas supply line connected to the first line, which is used to deliver air to the gas-liquid mixing device for mixing with ozone gas.

[0012] In one possible implementation, the ozone water heater further includes a second air pump located on a second air supply line, the second air pump being used to pressurize and drive the air in the second air supply line to mix with ozone gas.

[0013] In one possible implementation, if the gas-liquid mixing device is located on the first pipeline, the control device controls the opening of the first control valve to deliver water to the gas-liquid mixing device through the first pipeline.

[0014] If the gas-liquid mixing device is located on the third pipeline, the control device opens the first control valve and / or the second control valve to deliver water to the gas-liquid mixing device through the first pipeline and / or the third pipeline.

[0015] In one possible implementation, the ozone water heater also includes an operating device for a user to set the water output type of the ozone water heater based on the operating device. The water output type of the ozone water heater includes ozone microbubble cold water type and ozone microbubble hot water type.

[0016] The control methods for ozone water heaters include:

[0017] Determine the current water output type of the ozone water heater;

[0018] When the water flow information detected by the water flow detection device is received, the ozone generator and the first gas pump are started, and the first control valve and the second control valve are closed to deliver ozone gas to the gas-liquid mixing device.

[0019] When the first preset condition is met, the ozone generator and the first gas pump are shut down. The working state of the first switch control valve and the second switch control valve are controlled according to the position of the gas-liquid mixing device. The working state of the heating device is determined according to the current water output type of the ozone water heater. Cold water / hot water is delivered to the gas-liquid mixing device to mix with ozone gas to produce ozone microbubble cold water or ozone microbubble hot water.

[0020] When the second preset condition is met, the loop continues to execute the steps of controlling the ozone generator and the first air pump to start when the water flow information detected by the water flow detection device is received, and controlling the first control valve and the second control valve to close, until the ozone water heater stops working.

[0021] In one possible implementation, the ozone water heater further includes a second gas supply line and a second gas pump, the second gas pump being disposed on the second gas supply line; the method further includes:

[0022] When water flow information is received, the second air pump is started.

[0023] Based on the target ozone concentration, the operating time of the first and second air pumps is determined, and the operating status of the first and second air pumps is controlled according to their operating time.

[0024] In one possible implementation, achieving the first preset condition includes at least one of the following:

[0028] If the gas-liquid mixing device is installed on the first pipeline, the first control valve is opened to deliver cold water / hot water through the first pipeline to the gas-liquid mixing device;

[0029] If the gas-liquid mixing device is located on the third pipeline, the first control valve and / or the second control valve are opened to deliver cold water / hot water to the gas-liquid mixing device through the first pipeline and / or the third pipeline.

[0030] In one possible implementation, achieving the second preset condition includes at least one of the following:

[0031] The output of ozone microbubble cold water or ozone microbubble hot water reaches the preset output threshold.

[0032] The output time of ozone microbubble cold water or ozone microbubble hot water reaches the second preset time.

[0033] In one possible implementation, determining the operating status of the heating device based on the current water output type of the ozone water heater includes:

[0034] If the water output type is ozone microbubble hot water, the heating device will be activated when the water flow information detected by the water flow detection device is received again.

[0035] A computer-readable storage medium storing a computer program that, when executed by a processor, causes the processor to perform the steps of the control method for an ozone water heater as described above.

[0036] The beneficial effects of this invention are as follows:

[0037] The ozone water heater provided in this embodiment of the invention includes an inlet water pipe, a first gas supply pipe, an outlet water pipe, a heating device, a gas-liquid mixing device, an ozone generator, a first gas pump, a first control valve, a second control valve, a water flow detection device, and a control device. The inlet water pipe is connected to the heating device. The water flow detection device is located on the inlet water pipe to detect the water flow in the inlet water pipe. The outlet water pipe includes a first pipe, a second pipe, and a third pipe. The inlet ends of the first and second pipes are connected to the heating device, and the outlet ends of the first and second pipes are connected to the inlet end of the third pipe. The first control valve is located on the first pipe. The second control valve is located on the second pipeline; the first gas supply pipeline connects to the first pipeline, and the ozone generator and the first air pump are located on the first gas supply pipeline. The ozone generator generates ozone gas, and the first air pump pressurizes and drives the ozone gas into the gas-liquid mixing device. The gas-liquid mixing device is located on the first or third pipeline and is used to mix the input ozone gas with water to generate ozone microbubble water. The control device connects the first air pump, the first control valve, the second control valve, the ozone generator, and the heating device to control the working status of the ozone generator, the heating device, the first air pump, the first control valve, and the second control valve. This ozone water heater not only achieves multiple water output functions, such as ozone microbubble cold water and ozone microbubble hot water, to achieve a sterilization effect, but also avoids the situation where water cannot be output normally due to a small pressure difference by pressurizing the first air pump, thus improving the reliability of the water heater.

[0066] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0067] Example 1

[0068] like Figure 1 The diagram shown is a structural schematic of the ozone water heater 100 and its components provided in this embodiment.

[0069] Please see Figure 1 The ozone water heater 100 in this embodiment includes an inlet pipe 1, a first gas supply pipe 2, an outlet pipe 3, a heating device 4, a gas-liquid mixing device 5, an ozone generating device 6, a first air pump 7, a first control valve 8, a second control valve 9, a water flow detection device 10, and a control device (not shown in the figure).

[0070] The water inlet pipe 1 is connected to the heating device 4. The water flow detection device 10 is installed on the water inlet pipe 1 to detect the water flow in the water inlet pipe 1.

[0071] The water outlet pipe 3 includes a first pipe 31, a second pipe 32, and a third pipe 33. The inlet ends of the first pipe 31 and the second pipe 32 are connected to the heating device 4, and the outlet ends of the first pipe 31 and the second pipe 32 are connected to the inlet end of the third pipe 33. A first control valve 8 is installed on the first pipe 31 to control the flow of water within the first pipe 31. A second control valve 9 is installed on the second pipe 32 to control the flow of water within the second pipe 32.

[0072] The first gas supply line 2 is connected to the first line 31. The ozone generator 6 and the first gas pump 7 are installed on the first gas supply line 2. The ozone generator 6 generates ozone gas, and the first gas pump 7 pressurizes and drives the ozone gas generated by the ozone generator 6 to the gas-liquid mixing device 5.

[0073] The gas-liquid mixing device 5 is installed on the first pipeline 31. The gas-liquid mixing device 5 is used to mix the input ozone gas with water to produce ozone microbubble water.

[0074] The control device connects the first air pump 7, the first control valve 8, the second control valve 9, the ozone generator 6, and the heating device 4 to control the operating states of the heating device 4, the ozone generator 6, the first air pump 7, the first control valve 8, and the second control valve 9. By controlling the different operating states of the heating device 4, the ozone generator 6, the first air pump 7, the first control valve 8, and the second control valve 9, the ozone water heater 100 can achieve multiple functions, such as producing ordinary cold water, ordinary hot water, ozone microbubble cold water, ozone microbubble hot water, mixed cold water (a mixture of ordinary cold water and ozone microbubble cold water), and mixed hot water (a mixture of ordinary hot water and ozone microbubble hot water).

[0075] When producing ozone microbubble cold water or ozone microbubble hot water, the first air pump 7 pressurizes the water, significantly increasing the gas content in the gas-liquid mixing device 5. This increases the microbubble content in the produced ozone microbubble cold water or ozone microbubble hot water, effectively enhancing the microbubble effect. Furthermore, the pressurization via the first air pump 7 prevents water from failing to be produced due to insufficient pressure difference, improving the reliability of the water heater and enhancing the user experience.

[0076] For example, the ozone water heater 100 also includes a flow control valve 11, which is located on the first gas supply pipeline 2. The flow control valve 11 controls the flow state of ozone gas in the first gas supply pipeline 2. For example, the control device can control the heating device 4 and the ozone generator 6 to start / stop, control the first gas pump 7 to start / operate at a corresponding speed / stop, control the first control valve 8 to open / close, and control the second control valve 9 to open / close. By controlling the first control valve 8 to open, the control device delivers water through the first pipeline 31 to the gas-liquid mixing device 5.

[0077] As one possible implementation of this embodiment, the first control valve 8 and the second control valve 9 are solenoid valves, etc.

[0078] As one possible implementation of this embodiment, the water flow detection device 10 is a water flow sensor or the like.

[0079] As one possible implementation of this embodiment, the flow control valve 11 is a check valve or a shut-off valve. The check valve or shut-off valve can prevent backflow of ozone gas in the first gas supply line 2.

[0080] As one possible implementation of this embodiment, the control device is a main controller, etc.

[0081] As one possible implementation of this embodiment, the ozone water heater 100 also includes an operating device, which, for example, includes, but is not limited to, a touch screen display. The user can set the water output type of the ozone water heater 100 using the operating device. The water output types of the ozone water heater include ordinary cold water, ordinary hot water, ozone microbubble cold water, and ozone microbubble hot water, etc.

[0082] In one embodiment of this invention, the control device is connected to a first air pump 7, a first control valve 8, a second control valve 9, a heating device 4, an ozone generator 6, an operating device, and a water flow detection device 10. When the water flow detection device 10 detects water flow, it sends the detected water flow to the control device. The control device, based on the set water outlet type of the ozone water heater and the received water flow, controls the operating states of the heating device 4, the ozone generator 6, the first air pump 7, the first control valve 8, and the second control valve 9, ultimately controlling the operating state of the ozone water heater 100.

[0083] The following is combined Figure 1 Briefly describe the working process of the ozone water heater 100 in this embodiment:

[0084] (a) When the user sets the outlet water type of the ozone water heater to ozone microbubble cold water via the operating device, when the control device receives the water flow detected by the water flow detection device 10, the control device sends a corresponding control signal to the ozone generator 6 and the first air pump 7, controlling the ozone generator 6 and the first air pump 7 to start. Simultaneously, the control device sends a corresponding control signal to the first control valve 8 and the second control valve 9, controlling the first control valve 8 and the second control valve 9 to close, preventing water from flowing into the gas-liquid mixing device 5 through the first pipe 31. Furthermore, it prevents water from flowing out through the second pipe 32. With the ozone generator 6 and the first air pump 7 starting, the first control valve 8 closing, and the first air pump 7 driving the ozone gas generated by the ozone generator 6 to be transported to the gas-liquid mixing device 5 through the first gas supply pipe 2, the gas content in the gas-liquid mixing device 5 is significantly increased.

[0085] After a preset time or when the current liquid level of the gas-liquid mixing device 5 reaches a preset level, the control device controls the first control valve 8 to open and controls the ozone generator 6 and the first air pump 7 to close. Cold water is then supplied to the gas-liquid mixing device 5 through the first pipeline 31 to mix with the ozone gas in the gas-liquid mixing device 5 to generate ozone microbubble cold water. For example, a microbubble generator can be installed at the water point of the ozone water heater 100 (such as a faucet or shower head). The cold water with a high ozone gas content in the gas-liquid mixing device 5 is then processed by the microbubble generator to produce ozone microbubble cold water.

[0086] When the output flow rate of ozone microbubble cold water reaches the preset output flow rate threshold, or the output time of ozone microbubble cold water reaches the second preset time, the water flow rate detected by the water flow detection device 10 is received again. The control device sends a corresponding control signal to the ozone generator 6 and the first air pump 7 to start the ozone generator 6 and the first air pump 7. At the same time, the control device sends a corresponding control signal to the first control valve 8 and the second control valve 9 to close the first control valve 8 and the second control valve 9. The above control operation process is repeated to generate ozone microbubble cold water again until the ozone water heater 100 stops working.

[0087] (b) When the user sets the ozone water heater's output water type to ozone microbubble hot water via the operating device, when the control device receives the water flow detected by the water flow detection device 10, the control device sends a corresponding control signal to the ozone generator 6 and the first air pump 7, controlling the ozone generator 6 and the first air pump 7 to start. Simultaneously, the control device sends a corresponding control signal to the first control valve 8 and the second control valve 9, controlling the first control valve 8 and the second control valve 9 to close, preventing water from flowing into the gas-liquid mixing device 5 through the first pipe 31. Furthermore, it prevents water from flowing out through the second pipe 32. With the ozone generator 6 and the first air pump 7 starting, the first control valve 8 closes, and the first air pump 7 drives the ozone gas generated by the ozone generator 6 to be transported to the gas-liquid mixing device 5 through the first gas supply pipe 2, significantly increasing the gas content in the gas-liquid mixing device 5.

[0088] After a preset time or when the current liquid level of the gas-liquid mixing device 5 reaches the preset liquid level, the control device controls the first control valve 8 to open and controls the ozone generator 6 and the first air pump 7 to close. When the water flow detected by the secondary water flow detection device 10 is received, the heating device 4 is started to heat the water and then deliver hot water to the gas-liquid mixing device 5 to mix with the ozone gas in the gas-liquid mixing device 5 to generate ozone microbubble hot water.

[0089] When the output flow rate of ozone microbubble hot water reaches the preset output flow rate threshold, or the output time of ozone microbubble hot water reaches the second preset time, the water flow rate detected by the water flow detection device 10 is received again. The control device sends a corresponding control signal to the ozone generator 6 and the first air pump 7 to start the ozone generator 6 and the first air pump 7. At the same time, the control device sends a corresponding control signal to the first control valve 8 and the second control valve 9 to close the first control valve 8 and the second control valve 9. The above control operation process is repeated to generate ozone microbubble hot water again until the ozone water heater 100 stops working.

[0090] Example 2

[0091] Please see Figure 2The main difference between this embodiment and Embodiment 1 is that the gas-liquid mixing device 5 is located in the third pipeline 33. Since the water outlets of the first pipeline 31 and the second pipeline 32 are connected to the water inlet of the third pipeline 33, water can be supplied to the gas-liquid mixing device 5 through both the first pipeline 31 and the second pipeline 32. Furthermore, ozone gas in the first gas supply pipeline 2 can also be supplied to the gas-liquid mixing device 5 through the first pipeline 31 and the third pipeline 33.

[0092] Apart from the differences mentioned above, the structure of the ozone water heater 100 and its components provided in this embodiment can be optimized with reference to Embodiment 1, and will not be described in detail here.

[0093] Example 3

[0094] Please see Figure 3 The main difference between this embodiment and Embodiment 1 is that the ozone water heater 100 also includes a water pump 12, which is installed on the water inlet pipe 1. The water pump 12 is used to drive the water in the water inlet pipe 1 to flow to the heating device 4.

[0095] The following is combined Figure 3 Briefly describe the working process of the ozone water heater 100 in this embodiment:

[0096] (a) When the user sets the outlet water type of the ozone water heater to ozone microbubble cold water via the operating device, when the control device receives the water flow detected by the water flow detection device 10, the control device sends a corresponding control signal to the ozone generator 6 and the first air pump 7, controlling the ozone generator 6 and the first air pump 7 to start. Simultaneously, the control device sends a corresponding control signal to the first control valve 8 and the second control valve 9, controlling the first control valve 8 and the second control valve 9 to close, preventing water from flowing into the gas-liquid mixing device 5 through the first pipe 31. Furthermore, it prevents water from flowing out through the second pipe 32. With the ozone generator 6 and the first air pump 7 starting, the first control valve 8 closing, and the first air pump 7 driving the ozone gas generated by the ozone generator 6 to be transported to the gas-liquid mixing device 5 through the first gas supply pipe 2, the gas content in the gas-liquid mixing device 5 is significantly increased.

[0097] After a preset time or when the current liquid level of the gas-liquid mixing device 5 reaches a preset level, the control device controls the first control valve 8 to open and controls the ozone generator 6 and the first air pump 7 to close. Cold water is then supplied to the gas-liquid mixing device 5 through the first pipeline 31, mixing with the ozone gas in the gas-liquid mixing device 5 to generate ozone microbubble cold water. For example, a microbubble generator can be installed at the water point of the ozone water heater 100 (such as a faucet or shower head). Cold water with a high ozone gas content in the gas-liquid mixing device 5 is then processed by the microbubble generator to produce ozone microbubble cold water. Furthermore, the control device controls the water pump 12 to start, and the water pump 12 continues to operate during water use, increasing the system water pressure.

[0098] When the output flow rate of ozone microbubble cold water reaches the preset output flow rate threshold, or when the output time of ozone microbubble cold water reaches the second preset time, the control device shuts down the water pump 12, stopping its operation. It then receives the water flow rate detected by the water flow detection device 10 again and sends corresponding control signals to the ozone generator 6 and the first air pump 7, controlling them to start. Simultaneously, the control device sends corresponding control signals to the first control valve 8 and the second control valve 9, controlling them to close. This control operation process is repeated, generating ozone microbubble cold water again until the ozone water heater 100 stops operating.

[0099] (b) When the user sets the ozone water heater's output water type to ozone microbubble hot water via the operating device, when the control device receives the water flow detected by the water flow detection device 10, the control device sends a corresponding control signal to the ozone generator 6 and the first air pump 7, controlling the ozone generator 6 and the first air pump 7 to start. Simultaneously, the control device sends a corresponding control signal to the first control valve 8 and the second control valve 9, controlling the first control valve 8 and the second control valve 9 to close, preventing water from flowing into the gas-liquid mixing device 5 through the first pipe 31. Furthermore, it prevents water from flowing out through the second pipe 32. With the ozone generator 6 and the first air pump 7 starting, the first control valve 8 closes, and the first air pump 7 drives the ozone gas generated by the ozone generator 6 to be transported to the gas-liquid mixing device 5 through the first gas supply pipe 2, significantly increasing the gas content in the gas-liquid mixing device 5.

[0100] After a preset time or when the current liquid level of the gas-liquid mixing device 5 reaches a preset level, the control device controls the first control valve 8 to open and controls the ozone generator 6 and the first air pump 7 to close. When the water flow detected by the secondary water flow detection device 10 is received, the heating device 4 is started to heat the water and then deliver hot water to the gas-liquid mixing device 5 to mix with the ozone gas in the gas-liquid mixing device 5 to generate ozone microbubble hot water. Furthermore, the control device controls the water pump 12 to start, and the water pump 12 continues to work during water use to increase the system water pressure.

[0101] When the output flow rate of ozone microbubble hot water reaches the preset output threshold, or the output time of ozone microbubble hot water reaches the second preset time, the control device shuts off the water pump 12, stopping its operation. It then receives the water flow rate detected by the water flow detection device 10 again and sends corresponding control signals to the ozone generator 6 and the first air pump 7, controlling them to start. Simultaneously, the control device sends corresponding control signals to the first control valve 8 and the second control valve 9, controlling them to close. This control operation process is repeated to generate ozone microbubble hot water again until the ozone water heater 100 stops operating.

[0102] Apart from the differences mentioned above, the structure of the ozone water heater 100 and its components provided in this embodiment can be optimized with reference to Embodiment 1, and will not be described in detail here.

The second gas supply pipe 13 is used to transport air to the gas-liquid mixing device 5 to mix with ozone gas.

[0108] As one possible implementation of this embodiment, the ozone water heater 100 also includes a second air pump 14, which is disposed on the second air supply pipeline 13. The second air pump 14 is used to pressurize and drive the air in the second air supply pipeline 13 to mix with ozone gas.

[0110] Example 6

[0111] Please see Figure 6 The main difference between this embodiment and Embodiment 5 is that the gas-liquid mixing device 5 is located in the third pipeline 33. Since the water outlets of the first pipeline 31 and the second pipeline 32 are connected to the water inlet of the third pipeline 33, water can be supplied to the gas-liquid mixing device 5 through both the first pipeline 31 and the second pipeline 32. Furthermore, ozone gas in the first gas supply pipeline 2 can also be supplied to the gas-liquid mixing device 5 through the first pipeline 31 and the third pipeline 33.

[0112] Apart from the differences mentioned above, the structure of the ozone water heater 100 and its components provided in this embodiment can be optimized by referring to Embodiment 5, and will not be described in detail here.

[0117] Please see Figure 8 The main difference between this embodiment and Embodiment Six is ​​that the ozone water heater 100 also includes a water pump 12, which is installed on the water inlet pipe 1. The water pump 12 is used to drive the water in the water inlet pipe 1 to flow to the heating device 4.

[0118] Apart from the differences mentioned above, the structure of the ozone water heater 100 and its components provided in this embodiment can be optimized by referring to Embodiment Six, and will not be described in detail here.

[0119] The embodiments of this application also provide a control method for an ozone water heater. This method can be used in any of the ozone water heaters 100 provided in the above embodiments to realize a variety of different functions of the ozone water heater and improve the reliability of the ozone water heater.

[0120] Example 1

[0121] Please see Figure 9 , Figure 9 This is a schematic flowchart of the control method for an ozone water heater provided in this embodiment. The control method for the ozone water heater specifically includes steps S101 to S104.

[0122] S101. Determine the current water output type of the ozone water heater.

[0123] For example, the water output types of ozone water heaters include ozone microbubble cold water type, ozone microbubble hot water type, ordinary cold water type, and ordinary hot water type.

[0124] As one implementation of this embodiment, determining the current water output type of the ozone water heater may include: receiving water output type setting information sent by the operating device, wherein the water output type setting information is triggered by the user performing a setting operation based on the operating device; and determining the current water output type of the ozone water heater based on the water output type setting information.

[0125] For example, the operating device includes, but is not limited to, a touch screen display. Users can perform setting operations on the water outlet type of the ozone water heater based on the operating device, triggering the corresponding water outlet type setting information. The operating device sends the water outlet type setting information to the control device, thereby the control device receiving and acquiring the water outlet type setting information.

[0126] Based on the received water outlet type setting information, the current water outlet type of the ozone water heater is determined. For example, the current water outlet type of the ozone water heater is determined to be ozone microbubble cold water or ozone microbubble hot water.

[0127] S102. When the water flow information detected by the water flow detection device is received, the ozone generator and the first gas pump are started, and the first control valve and the second control valve are closed to deliver ozone gas to the gas-liquid mixing device.

[0128] Among them, ozone water heaters are Figures 1 to 8 The ozone water heater 100 is described above. When water flows in the inlet pipe 1, the water flow detection device 10 can detect the corresponding water flow information. This water flow information includes, but is not limited to, information such as the magnitude of the water flow. After detecting the corresponding water flow information, the water flow detection device 10 sends the water flow information to the control device, which then receives and acquires the water flow information.

[0129] The control device controls the ozone generator 6 and the first air pump 7 to start, and controls the first control valve 8 and the second control valve 9 to close. After the first control valve 8 is closed, water is no longer input into the gas-liquid mixing device 5, and the first air pump 7 starts, driving the ozone gas generated by the ozone generator 6 to be transported to the gas-liquid mixing device 5 through the first gas supply pipeline 2.

[0130] S103. When the first preset condition is met, the ozone generator and the first gas pump are shut down, and the working state of the first switch control valve and the second switch control valve are controlled according to the position of the gas-liquid mixing device. The working state of the heating device is determined according to the current water output type of the ozone water heater, so as to deliver cold water / hot water to the gas-liquid mixing device to mix with ozone gas to produce ozone microbubble cold water or ozone microbubble hot water.

[0131] The first preset condition includes at least one of the following: the duration of supplying ozone gas to the gas-liquid mixing device reaches the first preset duration; the current liquid level of the gas-liquid mixing device is within the preset liquid level range.

[0132] When the duration of supplying ozone gas to the gas-liquid mixing device 5 reaches the first preset duration, or when the current liquid level of the gas-liquid mixing device 5 is within the preset liquid level range, the control device controls the ozone generator 6 and the first gas pump 7 to shut down, stopping the supply of ozone gas to the gas-liquid mixing device 5. Furthermore, the control device controls the operating state of the first switch control valve 8 and the second switch control valve 9 based on the position of the gas-liquid mixing device 5, and determines the operating state of the heating device 4 based on the current water output type of the ozone water heater.

[0133] By controlling the different working states of the heating device 4, ozone generator 6, first air pump 7, first control valve 8 and second control valve 9, ozone gas and cold / hot water are input into the gas-liquid mixing device 5, thereby outputting ozone microbubble cold water or ozone microbubble hot water.

[0134] As one possible implementation of this embodiment, if the gas-liquid mixing device 5 is installed on the first pipeline 31, the control device controls the first control valve 8 to open so that cold water / hot water can be transported to the gas-liquid mixing device 5 through the first pipeline 31.

[0135] As another possible implementation of this embodiment, if the gas-liquid mixing device 5 is installed on the third pipeline 33, the control device controls the first control valve 8 and / or the second control valve 9 to open so as to transport cold water / hot water through the first pipeline 31 and / or the third pipeline 33 to the gas-liquid mixing device 5.

[0136] As one possible implementation of this embodiment, the working state of the heating device is determined according to the current water output type of the ozone water heater, including: if the water output type is ozone microbubble hot water, then when the water flow information detected by the water flow detection device is received again, the heating device is controlled to start.

[0137] When it is determined that the current water output type of the ozone water heater is ozone microbubble cold water, the control device controls the heating device 4 not to start, that is, not to heat the water, and directly delivers the cold water to the gas-liquid mixing device 5 to generate ozone microbubble cold water.

[0138] When it is determined that the current water output type of the ozone water heater is ozone microbubble hot water, when the water flow detected by the secondary water flow detection device 10 is received, the heating device 4 is controlled to start, and after heating the water, the hot water is delivered to the gas-liquid mixing device 5 to mix with the ozone gas in the gas-liquid mixing device 5 to produce ozone microbubble hot water.

[0139] S104. When the second preset condition is met, return to the loop and execute step S102 until the ozone water heater stops working.

[0140] Simultaneously, it is determined in real time whether the current conditions meet the second preset condition. For example, the second preset condition includes at least one of the following: the output flow rate of ozone microbubble cold water or ozone microbubble hot water reaches a preset output flow rate threshold, and the output duration of ozone microbubble cold water or ozone microbubble hot water reaches a second preset duration. The preset output flow rate threshold and the second preset duration can be flexibly set according to actual conditions and are not specifically limited here.

[0141] When the output of ozone microbubble cold water or ozone microbubble hot water reaches the preset output threshold, or when the output time of ozone microbubble cold water or ozone microbubble hot water reaches the second preset time, the operation of determining the current output type of the ozone water heater is returned again, so that ozone microbubble cold water or ozone microbubble hot water is always present in the gas-liquid mixing device 5.

[0142] like Figure 10 As shown, Figure 10 The specific process of producing ozone microbubble cold water for ozone water heater 100:

[0143] When the user sets the ozone water heater's output type to ozone microbubble cold water via the operating device, when the control device receives the water flow detected by the water flow detection device 10, the control device sends a corresponding control signal to the ozone generator 6 and the first air pump 7, controlling the ozone generator 6 and the first air pump 7 to start. Simultaneously, the control device sends corresponding control signals to the first control valve 8 and the second control valve 9, controlling the first control valve 8 and the second control valve 9 to close, preventing water from flowing into the gas-liquid mixing device 5 through the first pipe 31. Furthermore, it prevents water from flowing out through the second pipe 32. With the ozone generator 6 and the first air pump 7 starting, the first control valve 8 closing, and the first air pump 7 driving the ozone gas generated by the ozone generator 6 to be transported to the gas-liquid mixing device 5 through the first gas supply pipe 2, significantly increasing the gas content in the gas-liquid mixing device 5.

[0144] After a preset time or when the current liquid level of the gas-liquid mixing device 5 reaches a preset level, i.e., when the first preset condition is met, the control device controls the first control valve 8 to open and controls the ozone generator 6 and the first air pump 7 to close. Cold water is then supplied to the gas-liquid mixing device 5 through the first pipeline 31 to mix with the ozone gas in the gas-liquid mixing device 5 to generate ozone microbubble cold water. For example, a microbubble generator is installed at the water point of the ozone water heater 100 (such as a faucet, shower head, etc.). The cold water with a high ozone gas content in the gas-liquid mixing device 5 is processed by the microbubble generator to produce ozone microbubble cold water.

[0145] When the output flow rate of ozone microbubble cold water reaches a preset threshold, or the output duration of ozone microbubble cold water reaches a second preset duration (i.e., when the second preset condition is met), the water flow rate detected by the water flow detection device 10 is received again. The control device sends a corresponding control signal to the ozone generator 6 and the first air pump 7 to start them. Simultaneously, the control device sends a corresponding control signal to the first control valve 8 and the second control valve 9 to close them. This control operation process is repeated to generate ozone microbubble cold water again until the ozone water heater 100 stops working.

[0146] like Figure 11 As shown, Figure 11 The specific process of producing ozone microbubble hot water for ozone water heater 100:

[0147] When the user sets the ozone water heater's output type to ozone microbubble hot water via the operating device, when the control device receives the water flow detected by the water flow detection device 10, the control device sends a corresponding control signal to the ozone generator 6 and the first air pump 7, controlling the ozone generator 6 and the first air pump 7 to start. Simultaneously, the control device sends corresponding control signals to the first control valve 8 and the second control valve 9, controlling the first control valve 8 and the second control valve 9 to close, preventing water from flowing into the gas-liquid mixing device 5 through the first pipe 31. Furthermore, it prevents water from flowing out through the second pipe 32. With the ozone generator 6 and the first air pump 7 starting, and the first control valve 8 closing, the first air pump 7 drives the ozone gas generated by the ozone generator 6 to be transported to the gas-liquid mixing device 5 through the first gas supply pipe 2, significantly increasing the gas content in the gas-liquid mixing device 5.

[0148] After a preset time or when the current liquid level of the gas-liquid mixing device 5 reaches the preset liquid level, i.e. when the first preset condition is met, the control device controls the first control valve 8 to open and controls the ozone generator 6 and the first air pump 7 to close. When the water flow detected by the secondary water flow detection device 10 is received, the heating device 4 is started to heat the water and then deliver hot water to the gas-liquid mixing device 5 to mix with the ozone gas in the gas-liquid mixing device 5 to generate ozone microbubble hot water.

[0149] When the output flow rate of ozone microbubble hot water reaches a preset threshold, or the output duration of ozone microbubble hot water reaches a second preset duration (i.e., when the second preset condition is met), the water flow rate detected by the water flow detection device 10 is received again. The control device sends a corresponding control signal to the ozone generator 6 and the first air pump 7 to start them. Simultaneously, the control device sends a corresponding control signal to the first control valve 8 and the second control valve 9 to close them. This control operation process is repeated to generate ozone microbubble hot water again until the ozone water heater 100 stops working.

[0150] Example 2

[0151] The main difference between this embodiment and Embodiment 1 is that the ozone water heater 100 further includes a second gas supply pipe 13 and a second air pump 14, wherein the second air pump 14 is installed on the second gas supply pipe 13. The control method for the ozone water heater 100 also includes:

[0152] When the water flow information is received, the second air pump is controlled to start;

[0153] Based on the target ozone concentration, the operating time of the first and second air pumps is determined, so as to control the working state of the first and second air pumps according to the operating time of the first and second air pumps.

[0154] When the control device receives the water flow detected by the water flow detection device 10, it sends a corresponding control signal to the ozone generator 6 and the first air pump 7, controlling them to start. Simultaneously, the control device sends a corresponding control signal to the second air pump 14, controlling it to start. In this way, the second air pump 14 pressurizes and drives the air in the second air supply line 13 into the gas-liquid mixing device 5, where it mixes with ozone gas.

[0155] For example, a target ozone concentration can be preset. Based on the target ozone concentration, the operating time of the first air pump 7 and the second air pump 14 is determined. Different target ozone concentrations correspond to different operating times for the first air pump 7 and the second air pump 14. By controlling the operating times of the first air pump 7 and the second air pump 14, the concentration of ozone gas delivered to the gas-liquid mixing device 5 is adjusted to the target ozone concentration. When the actual operating time of the first air pump 7 and the second air pump 14 reaches their respective corresponding operating times, they are controlled to stop operating.
