Description

Technical Field

[0001] This application relates to the field of water heater technology, and in particular to a gas water heater device, control method, and computer device. Background Technology

[0002] With the popularization of healthy bathing concepts, micro-nano bubble technology has been gradually applied to gas water heater products due to its advantages such as strong cleaning power, delicate skin feel, and water and energy saving. Its basic principle is: dissolving air in high-pressure water to form saturated dissolved air water, and then releasing the pressure to release the gas in the form of micro-nano bubbles, thereby achieving functional hot water output.

[0003] To replenish gas into the dissolved air tank, some solutions employ low-pressure air pumps. However, since the water pressure in domestic water supply systems is typically 0.15–0.3 MPa, while the output pressure of low-cost micro air pumps is often less than 0.15 MPa, it is difficult to overcome the system back pressure and directly inject gas into the pressurized dissolved air tank. Therefore, existing technologies often have to adopt measures such as "shutting off the water inlet" or "throttling and reducing pressure" to temporarily lower the internal pressure of the dissolved air tank to match the operating conditions of the air pump.

[0004] However, this operation can cause water flow interruption or a sudden drop in water pressure at the user end, which in turn can lead to drastic fluctuations in water temperature (such as a sudden release of hot or cold water), affecting not only the comfort of bathing but also the risk of scalding, thus impacting the user experience. Summary of the Invention

[0005] This application provides a gas water heater device, control method, and computer device, aiming to solve the problem that when replenishing gas into the dissolved gas tank, it is necessary to cut off the water inlet or reduce the water inlet pressure, which leads to water flow interruption or sudden drop in water pressure at the user end, affecting the user experience.

[0006] In a first aspect, embodiments of this application provide a gas water heater device, which includes a gas water heater body, a dissolved gas tank, a gas inlet module, a pressure relief module, a first control valve, a second control valve, and a controller; The gas water heater body is equipped with a heat exchanger and a burner; the input end of the heat exchanger is connected to the water inlet pipe, the output end of the heat exchanger is connected to the input end of the dissolved gas tank through the first control valve and the air inlet module respectively, and the output end of the dissolved gas tank is connected to the water outlet pipe through the second control valve and the pressure relief module respectively. The controller is electrically connected to the first control valve and the second control valve, and is used to control the working state of the first control valve and the second control valve according to the operating mode of the gas water heater; wherein, when the operating mode is the bubble generation mode, the first control valve is controlled to be in the open state and the second control valve is controlled to be in the closed state. When the operating mode is the air replenishment mode, the first control valve is controlled to be closed and the second control valve is controlled to be open.

[0007] A further technical solution is that the gas water heater also includes a gas pump and a one-way valve, wherein the gas pump is connected to the gas inlet module through the one-way valve.

[0008] A further technical solution is that the gas water heater also includes a water flow sensor, which is installed in the water inlet pipe.

[0009] A further technical solution is that both the intake module and the depressurization module adopt a Venturi structure.

[0010] Secondly, this application provides a control method for a gas water heater, applied to the gas water heater as described above, wherein the controller is used to execute the steps of the control method for the gas water heater, and the control method for the gas water heater includes: Obtain the operating mode of the gas water heater; Based on the operating mode, the working states of the first control valve and the second control valve are controlled.

[0011] A further technical solution is that, based on the operating mode, controlling the working state of the first control valve and the second control valve includes: When the operating mode is bubble generation mode, the first control valve is controlled to be in the open state and the second control valve is controlled to be in the closed state; When the operating mode is the air replenishment mode, the first control valve is controlled to be closed and the second control valve is controlled to be open.

[0012] A further technical solution is that the gas water heater further includes a gas pump and a one-way valve, the gas pump being connected to the gas inlet module via the one-way valve, and the method comprising: When the operating mode is the air replenishment mode, the first control valve is closed, and the second control valve, the air pump, and the check valve are open.

[0013] A further technical solution is that obtaining the operating mode of the gas water heater includes: Obtain the total water flow rate of the gas water heater; Determine whether the total outflow rate is greater than or equal to the preset flow rate value; If so, the operating mode of the gas water heater is determined to be the gas replenishment mode.

[0014] A further technical solution is that the method further includes: Obtain the gas replenishment time of the dissolved gas tank; Determine whether the gas replenishment time is greater than a preset time threshold; If so, then turn off the air pump; If not, return to the step of obtaining the gas replenishment time of the dissolved gas tank.

[0015] Thirdly, embodiments of this application also provide a computer device, which includes a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the above-described method.

[0016] This application provides a gas water heater device, a control method, and a computer device. The gas water heater device includes a gas water heater body, a dissolved gas tank, an air inlet module, a pressure relief module, a first control valve, a second control valve, and a controller. The gas water heater body includes a heat exchanger and a burner. The input end of the heat exchanger is connected to a water inlet pipe, and the output end of the heat exchanger is connected to the input end of the dissolved gas tank via the first control valve and the air inlet module. The output end of the dissolved gas tank is connected to a water outlet pipe via the second control valve and the pressure relief module. The controller is electrically connected to the first control valve and the second control valve and is used to control the operating state of the first control valve and the second control valve according to the operating mode of the gas water heater device. Specifically, when the operating mode is bubble generation mode, the first control valve is controlled to be in the open state and the second control valve is controlled to be in the closed state; when the operating mode is gas replenishment mode, the first control valve is controlled to be in the closed state and the second control valve is controlled to be in the open state.

[0017] This embodiment of the application sets up an air inlet module passage and a first control valve passage in parallel between the output end of the heat exchanger and the input end of the dissolved air tank, and a pressure relief module passage and a second control valve passage in parallel between the output end of the dissolved air tank and the water outlet pipe. During the micro-nano bubble generation stage, the controller opens the first control valve and closes the second control valve. Water flows sequentially through the first control valve, the dissolved air tank, and the pressure relief module, completing gas dissolution and micro-nano bubble precipitation. During the dissolved air tank replenishment stage, the controller closes the first control valve and opens the second control valve. Water flows into the dissolved air tank through the air inlet module and exits through the second control valve, switching to a pipeline without a pressure relief module. This effectively reduces the replenishment pressure. Thus, during the replenishment stage, there is no need to interrupt the water supply or reduce the water pressure. The water flow is continuously and stably supplied to the user, ensuring consistent water flow during both the micro-nano bubble generation and dissolved air tank replenishment stages. This avoids problems such as water flow interruption, sudden temperature changes, or fluctuating temperatures caused by stopping the water inlet or throttling pressure reduction in traditional solutions, improving bathing comfort and safety.

[0018] Furthermore, since micro-nano bubble generation technology is based on the pressure-release method, it requires the gas to be pressurized and dissolved in a gas dissolving tank, and then the dissolved gas is released through a pressure release device. In traditional micro-nano bubble gas water heaters, the pressure release device is usually located outside the machine, at the user end (such as a dedicated shower head or aerator), or after the water outlet of the water heater. This makes it impossible for users to control the start and stop of the pressure release function independently, and it is necessary to rely on specific accessories to achieve the bubble effect.

[0019] In contrast, this application integrates the dissolved gas tank, gas inlet module, pressure relief module, and control valve all inside the gas water heater body, eliminating the need for an additional dedicated pressure relief device at the water outlet. Users can freely choose any conventional bathroom accessories such as shower heads and faucets, which not only retains the flexibility of personalized matching but also ensures the stability and reliability of the micro-nano bubble function, improving the product's compatibility and ease of use.

[0031] To address the aforementioned issues, this application provides a gas water heater device and its control method, which ensures consistent water flow during the two stages of micro-nano bubble generation and dissolved gas tank replenishment. This avoids water flow interruptions caused by water inlet shut-off or pressure reduction in traditional solutions, thereby improving bathing comfort and safety.

[0032] See Figure 1 and Figure 2 The gas water heater device 10 provided in this application includes a gas water heater body, a dissolved gas tank 13, an air inlet module 14, a pressure relief module 15, a first control valve 16, a second control valve 17, and a controller.

[0033] The gas water heater body is provided with a heat exchanger 11 and a burner 12; the input end of the heat exchanger 11 is connected to the water inlet pipe 01, the output end of the heat exchanger 11 is connected to the input end of the dissolved gas tank 13 through the first control valve 16 and the air inlet module 14 respectively, and the output end of the dissolved gas tank 13 is connected to the water outlet pipe 02 through the second control valve 17 and the pressure relief module 15 respectively. The controller is electrically connected to the first control valve 16 and the second control valve 17, and is used to control the working state of the first control valve 16 and the second control valve 17 according to the operating mode of the gas water heater equipment 10. When the operating mode is bubble generation mode, the first control valve 16 is controlled to be in the open state and the second control valve 17 is controlled to be in the closed state; wherein, the water flow path is as follows: Figure 1 As shown.

[0034] When the operating mode is the air replenishment mode, the first control valve 16 is controlled to be closed and the second control valve 17 is controlled to be open, wherein the water flow path is as follows: Figure 2 As shown.

[0035] In this embodiment, an air intake module 14 passage and a first control valve 16 passage are arranged in parallel between the output end of the heat exchanger 11 and the input end of the dissolved air tank 13, and a pressure relief module 15 passage and a second control valve 17 passage are arranged in parallel between the output end of the dissolved air tank 13 and the water outlet pipe 02. During the micro-nano bubble generation stage, the controller opens the first control valve 16 and closes the second control valve 17. Water flows sequentially through the first control valve 16, the dissolved air tank 13, and the pressure relief module 15, completing gas dissolution and micro-nano bubble precipitation. During the gas replenishment stage of the dissolved air tank 13, the controller closes the first control valve 16 and opens the second control valve 17. Water flows into the dissolved air tank 13 through the air inlet module 14 and is directly output through the second control valve 17, switching to a pipeline without the pressure relief module 15. This effectively reduces the gas replenishment pressure. Thus, during the gas replenishment stage, there is no need to interrupt the water supply or reduce the water pressure. The water flow is continuously and stably supplied to the user, ensuring consistent water flow during both the micro-nano bubble generation and dissolved air tank 13 replenishment stages. This avoids problems such as water flow interruption, sudden water temperature changes, or sudden temperature fluctuations caused by water inlet throttling or pressure reduction in traditional solutions, improving bathing comfort and safety.

[0036] Furthermore, since micro-nano bubble generation technology is based on the pressure-release method, it requires the gas to be pressurized and dissolved in a gas dissolving tank, and then the dissolved gas is released through a pressure release device. In traditional micro-nano bubble gas water heaters, the pressure release device is usually located outside the machine, at the user end (such as a dedicated shower head or aerator), or after the water outlet of the water heater. This makes it impossible for users to control the start and stop of the pressure release function independently, and it is necessary to rely on specific accessories to achieve the bubble effect.

[0037] In contrast, this application integrates the dissolved gas tank, gas inlet module, pressure relief module, and control valve all inside the gas water heater body, eliminating the need for an additional dedicated pressure relief device at the water outlet. Users can freely choose any conventional bathroom accessories such as shower heads and faucets, which not only retains the flexibility of personalized matching but also ensures the stability and reliability of the micro-nano bubble function, improving the product's compatibility and ease of use.

[0038] In some possible implementations, the first control valve 16 and the second control valve 17 can be electric shut-off valves, which have the advantages of rapid opening and closing, good sealing, high control accuracy and easy integration with the controller. They can reliably realize the switching between the main path and the bypass flow path, thereby ensuring a smooth and undisturbed transition between the micro-nano bubble generation mode and the dissolved gas tank replenishment mode.

[0039] In some possible implementations, the gas water heater device 10 further includes an air pump 18 and a one-way valve 19, the air pump 18 being connected to the air intake module 14 via the one-way valve 19.

[0040] In complex installation environments with low water pressure, long pipelines, or high back pressure at the water end, relying solely on water flow self-suction injection may not be sufficient to effectively draw in a sufficient amount of gas. Therefore, this embodiment can add an air pump 18 to actively inject air into the air intake module 14 or the dissolved air tank 13, significantly enhancing the air supply capacity and ensuring stable operation of the micro-nano bubble function under various working conditions.

[0041] Furthermore, a one-way valve 19 is installed between the air pump 18 and the air intake module 14, which can effectively prevent high-pressure water from flowing back into the air pump 18 when the machine is stopped or in an abnormal state, thus avoiding damage to the air pump 18, short circuit of the motor or internal contamination, and improving the safety and durability of the whole machine.

[0042] In installation environments with long pipelines and high resistance at the water end, the air pump 18 can be used to actively supply air; while in most conventional water use scenarios, effective air replenishment can be achieved solely by the self-attracting and ejecting effect generated by the water flow through the air intake module 14, without the need for the air pump 18.

[0043] This embodiment adopts a "self-priming + air pump" hybrid gas supply strategy—under normal operating conditions, it prioritizes the use of energy-free self-priming injection, and automatically activates the air pump 18 to assist in gas replenishment when gas is insufficient. This satisfies the performance stability requirements of high-end users while retaining the possibility of low-power operation, achieving a flexible balance between performance and energy efficiency.

[0044] In some possible implementations, the gas water heater device 10 further includes a water flow sensor 20, which is disposed on the water inlet pipe 01.

[0045] In some possible implementations, both the intake module 14 and the depressurization module 15 employ a venturi structure.

[0046] In practical use, most users' water pressure is between 0.15-0.8 MPa, which is much higher than the working pressure of the micro air pump. Based on this, this embodiment uses a venturi tube to reduce the pressure required for air intake. The pressure reduction effect of the venturi tube is affected by its back pressure. The greater the back pressure, the smaller the reduction effect on air intake. The factor affecting the back pressure is the pipeline resistance at the lower end of the air intake venturi tube. The greater the pipeline resistance, the greater the back pressure.

[0047] The pressure relief module 15 also reduces the water flow pressure through the Venturi structure, allowing gas to be released under low pressure. The Venturi structure is essentially for throttling and acceleration, so the overall resistance coefficient of the air intake module 14 and the pressure relief module 15 used in this application is relatively high.

[0048] Since the actual water supply pressure in user applications is typically in the range of 0.15–0.8 MPa, which is far higher than the effective working pressure of a micro air pump, this application utilizes a Venturi structure to achieve pump-free or low-pump-dependent gas introduction. Specifically, the air intake module 14 utilizes the Venturi effect to generate a local negative pressure at the throat, thereby self-drawing air in; however, this negative pressure effect is significantly affected by the downstream back pressure—the higher the back pressure, the weaker the negative pressure, and the lower the air intake efficiency. The back pressure is mainly determined by the resistance of the pipeline at the rear end of the air intake module (including the dissolved air tank and subsequent flow channels); the greater the resistance, the higher the back pressure, and the worse the air intake effect.

[0049] On the other hand, the pressure relief module 15 is also based on the Venturi principle. It accelerates the flow by throttling, causing a sudden drop in water pressure, which in turn causes dissolved gases to precipitate in the low-pressure zone, forming micro- and nano-bubbles. Since the Venturi structure is essentially a throttling element, it will result in high fluid resistance whether used for air intake or pressure relief.

[0050] Based on this, this application designs the overall resistance coefficients of the air intake module 14 and the pressure relief module 15 to be similar or matched. In this way, in normal working mode (water flows through the dissolved air tank → pressure relief module) and in air replenishment mode (water flows through the air intake module → dissolved air tank), the total flow resistance of the system is basically the same. Under the premise that the water supply pressure remains unchanged, the water flow at the user end can be kept constant, thereby effectively achieving the technical effect of no fluctuation in water flow during air replenishment.

[0051] Based on the gas water heater equipment described in the above embodiments, this application also provides a control method for the gas water heater equipment, as detailed in the following sections. Figure 3 , Figure 3 This is a flowchart illustrating a first embodiment of a control method for a gas water heater provided in this application. The controller is used to execute the steps of the control method for the gas water heater, which includes: Step 110: Obtain the operating mode of the gas water heater.

[0052] Step 120: Based on the operating mode, control the working state of the first control valve and the second control valve.

[0053] In some possible implementations, step 120, namely controlling the operating states of the first control valve and the second control valve based on the operating mode, includes: Step 121: When the operating mode is bubble generation mode, the first control valve is controlled to be in the open state and the second control valve is controlled to be in the closed state.

[0054] Step 122: When the operating mode is the air replenishment mode, the first control valve is controlled to be closed and the second control valve is controlled to be open.

[0055] In some possible implementations, obtaining the operating mode of the gas water heater includes: Step 21: Obtain the total water flow rate of the gas water heater.

[0056] Step 22: Determine whether the total outflow rate is greater than or equal to the preset flow rate value.

[0057] Step 23: If yes, then determine that the operating mode of the gas water heater is the gas replenishment mode.

[0058] In some possible implementations, the gas water heater further includes a gas pump and a one-way valve, the gas pump being connected to the gas inlet module via the one-way valve, the method comprising: Step 123: When the operating mode is the air replenishment mode, the first control valve is controlled to be closed, and the second control valve, the air pump and the check valve are controlled to be open.

[0059] In some possible implementations, the method further includes: Step 124: Obtain the gas replenishment time of the dissolved gas tank; Step 125: Determine whether the gas replenishment time is greater than a preset time threshold; Step 126: If so, then turn off the air pump; Step 127: If not, return to the step of obtaining the gas replenishment time of the dissolved gas tank.

[0060] Based on the gas water heater equipment and control method provided in the above embodiments, the control method for the gas water heater equipment provided in this application can be referred to the following process: 1) Turn on the gas water heater; 2) Determine if the micro / nano bubble program has started; If yes, then proceed to step 3); otherwise, end the operation. 3) Open the first control valve and close the second control valve; 4) Record the cumulative outflow rate q using a flow meter; 5) Determine whether the cumulative outflow rate q is greater than or equal to the preset flow rate value q0; If yes, then execute step 6; otherwise, return step 4. When the cumulative outflow rate q (i.e., the total outflow rate) is greater than or equal to the preset flow rate value q0, it indicates that the dissolved air tank needs to be replenished with gas, i.e., the gas replenishment mode is entered.

[0061] The cumulative outflow rate q depends on factors such as the volume of the dissolved air tank, water pressure, water flow rate, and the structure of the pressure relief module.

[0062] The preset time threshold t0 can be set and adjusted according to the actual situation, and this application does not limit it.

[0063] 6) Open the second control valve, air pump, and check valve, and close the first control valve; 7) Record the gas replenishment time t of the dissolved gas tank; When an air pump is provided, the running time of the air pump can be used as the air replenishment time t. When there is no air pump, a timer can be used to record the air replenishment time of the dissolved gas tank.

[0064] The replenishment time t depends on factors such as the flow rate of the air pump, the volume of the dissolved air tank, and the water flow rate. 8) Determine whether the gas replenishment time t is greater than the preset time threshold t0; The preset time threshold t0 can be set and adjusted according to the actual situation, and this application does not limit it.

[0065] If yes, then turn off the air pump; if not, return to step 7).

[0066] 9) Turn off the air pump; 10) Reset the air replenishment time t and cumulative outflow rate q to zero; 11) End operation.
