Description

Technical Field

[0001] The invention relates to a preheating cycle and a pressure-boosting control method with a connecting valve. Background Art

[0002] The working principle of the water heater and its water system with zero cold water function in the prior art is: when the user is not using hot water, the water heater detects that the water temperature in the conduit is lower than the set temperature and starts the circulating water pump in the water heater. After the water pump starts running, the water in the pipe will flow into the water heater for heating. After the water in the pipe is heated to the specified temperature, the water pump stops running and the water heater also stops working.

[0003] For households that do not follow the return pipe, when installing the gas water heater, the faucet at the farthest end of the water pipe in the home will be found. In order to prevent cold water from flowing back into the hot water pipe when using hot water, a one-way valve is generally installed here. However, installing a one-way valve here requires that the water resistance of the hot water pipe of the last faucet is greater than the water resistance of the cold water pipe. But when the water resistance of the hot water pipe is less than the water resistance of the cold water pipe, when the user turns on the cold water, part of the water flows from the hot water pipe and part flows from the cold water pipe, causing hot water to come out when the cold water is turned on, causing trouble for the user. In addition, when using a circulating pump to pressurize the water flow, using a circulating structure will also cause the hot water flowing out of the water heater to pass through the circulating pump again, causing the hot water to be heated again, thereby making the water temperature higher and exceeding the safe temperature when used. At the same time, the circulating pump cannot play a better role in pressurization.

[0004] Therefore, there is an urgent need for a preheating cycle and boost control method with a connecting valve to ensure that the preheating and boost functions can operate better through simple signal transmission. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the defects of the prior art caused by the one-way valve in the cold water to discharge hot water and the poor boosting effect and reduced safety caused by the preheating and circulation running together, and to provide a preheating cycle and boosting control method with a connecting valve.

[0006] The present invention solves the above technical problems through the following technical solutions:

[0007] The present invention provides a preheating circulation and boost control method with a connecting valve, which comprises a gas water heater, a plurality of water outlet pipelines from the far end to the near end of the gas water heater, a circulating pump and a connecting valve, wherein the connecting valve comprises a valve core, a water flow hole, a hot water outlet and a cold water outlet, wherein the valve core is used to block the water flow hole, and the connecting valve is connected to the water outlet pipeline at the farthest end, and the connecting valve further comprises a controller, a first flow sensor and a small hole, wherein the controller is used to control the valve core to block or open the water flow hole; the first flow sensor is arranged in the connecting valve, and is used to detect the flow rate of water in the connecting valve; when the valve core closes the water flow hole, the small hole is formed between the valve core and the water flow hole, the small hole connects the hot water outlet and the cold water outlet, and the inner diameter of the small hole is smaller than the inner diameter of the water flow hole;

[0008] The steps of the preheating cycle and boost control method with a connecting valve include: judging and selecting to enter the preheating cycle mode, or to enter the boost mode; the preheating cycle mode includes: the circulation pump outputs a first flow signal; the first flow sensor receives the first flow signal within a specified time; the controller controls the valve core to open the water flow hole; and the preheating cycle mode ends; the boost mode includes: the circulation pump outputs a second flow signal; the first flow sensor receives the second flow signal within a specified time; the controller controls the valve core to close the water flow hole; and the boost mode ends; the flow signal received by the first flow sensor for a period of time is 0; the controller controls the valve core to open the water flow hole.

[0009] In the present technical solution, by judging and selecting to enter the preheating cycle mode, or to enter the boosting mode, in the two states of entering the preheating and boosting, two-stage flow signals are output respectively to control the valve core to open in the preheating cycle mode and close in the boosting mode, thereby ensuring that hot water will not flow out when turning on the cold water, and that the boosting effect is good during boosting and the safety of boosting is improved.

[0010] Preferably, the step of judging and selecting to enter the preheating cycle mode or the boosting mode includes: judging whether there is a need to enter the preheating cycle, if so, entering the preheating cycle mode; if not, judging whether there is a need to enter the boosting mode, if there is a boosting demand, entering the boosting mode, if there is no boosting demand, maintaining the initial state.

[0011] In the present technical solution, it is judged and selected to enter the preheating cycle mode, or when entering the boost mode, it is first judged whether there is a need to enter the preheating cycle, and the need for the preheating cycle can be given priority to ensure that the preheating function is processed first.

[0012] Preferably, the control method also includes a temperature sensor, which is arranged at the water outlet of the gas water heater. The step of determining whether there is a need to enter a preheating cycle also includes: the user clicks to enter the preheating mode, or the temperature sensor detects that the water outlet temperature is lower than a preset temperature.

[0013] In this technical solution, the preheating mode can be entered manually or automatically by clicking or detecting with a temperature sensor, thereby improving the degree of automation.

[0014] Preferably, the control method also includes a second flow sensor, which is connected to the circulation pump and used to detect the flow rate of water in the circulation pump. The step of the circulation pump outputting a first flow signal also includes: the circulation pump generates the first flow signal; the second flow sensor detects the first flow signal; if the first flow signal is consistent with the set signal, the first flow sensor receives the first flow signal within a specified time, and the controller controls the valve core to open the water flow hole; if the first flow signal is inconsistent with the set signal, it is terminated.

[0015] In the present technical solution, the second flow sensor detects the first flow signal. If the first flow signal is consistent with the set signal, the controller controls the valve core to open the water flow hole. The second flow sensor detects whether the flow rate of the water flow of the circulating pump is consistent with the set signal to ensure stability and prevent malfunctions in the preheating function. If not, it can be terminated in time.

[0016] Preferably, the step in which the first flow sensor receives the first flow signal within a specified time further includes: the first flow sensor receives the first flow signal as three flow square waves within the specified time.

[0017] In the present technical solution, the first flow signal is a three-flow square wave. The setting of the flow square wave facilitates detection, and setting the three-flow square wave improves the accuracy of detection.

[0018] Preferably, the step of ending the preheating cycle mode further includes: the user cancels entering the preheating mode, or the water outlet temperature detected by the temperature sensor is greater than or equal to a preset temperature.

[0019] In this technical solution, the preheating mode can be ended manually or automatically by clicking or detecting with a temperature sensor, thereby improving the degree of automation.

[0021] In the present technical solution, the second flow signal is detected by the second flow sensor. If the second flow signal is consistent with the set signal, the controller controls the valve core to close the water flow hole. The second flow sensor is used to detect whether the flow rate of the water flow of the circulating pump is consistent with the set signal to ensure stability and prevent malfunction of the boost function. If it is inconsistent, it can be terminated in time.

[0022] Preferably, the step in which the first flow sensor receives the second flow signal within a specified time includes: the first flow sensor receives the second flow signal within the specified time as detecting flow, but fails to detect three flow square waves.

[0023] In the present technical solution, the second flow signal is that the flow is detected, but the three-way flow square wave is not detected. The flow is simple and easy to obtain, which can effectively ensure the normal operation of the boost function.

[0024] Preferably, the suspension also includes completely stopping, or causing the circulation pump to generate a signal again.

[0025] In the present technical solution, the termination is when the second flow signal is inconsistent with the set signal. Complete stopping can be detected in time to prevent affecting normal operation. The circulating pump can regenerate the signal and re-output the signal to improve automation.

[0061] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0062] Example 1

[0063] like Figures 1 to 5 As shown, the present invention provides a preheating circulation and boost control method with a connecting valve, which includes a gas water heater 1, a plurality of water outlet pipes 2 from the far end to the near end of the gas water heater 1, a circulating pump 3 and a connecting valve 5, the connecting valve 5 includes a valve core 500, a water flow hole 501, a hot water port 502 and a cold water port 503, the valve core 500 is used to block the water flow hole 501, the connecting valve 5 is connected to the farthest water outlet pipe 2, and the connecting valve 5 also includes a controller 504, a first flow sensor The controller 504 is used to control the valve core 500 to block or open the water flow hole 501; the first flow sensor 505 is arranged in the connecting valve 5, and is used to detect the flow rate of the water flow in the connecting valve 5; when the valve core 500 closes the water flow hole 501, a small hole 506 is formed between the valve core 500 and the water flow hole 501, and the small hole 506 is connected to the hot water inlet 502 and the cold water inlet 503, and the inner diameter of the small hole 506 is smaller than the inner diameter of the water flow hole 501;

[0064] In this embodiment, the small hole 506 is provided on the valve core 500. In order to achieve blocking, a certain flow rate needs to pass through the small hole 506. Those skilled in the art can design the small hole 506 of corresponding size according to the requirements of the present invention. The connecting valve 5 also includes a solenoid valve coil 507, which cooperates with the valve core 500 and controls the valve core 500 to block or open the water flow hole 501 by turning on and off the power. The connecting valve 5 also includes a reset member 508, which is connected to the valve core 500 and applies force to the valve core 500 so that the valve core 500 blocks the water flow hole 501. Specifically, the reset member 508 is a spring. When the solenoid valve coil 507 is energized, the reset member 508 is compressed, and the valve core 500 opens the water flow hole 501; when the solenoid valve is de-energized, the reset member 508 returns to a normal state, and the valve core 500 blocks the water flow hole 501. The connecting valve 5 further comprises a one-way valve 509 , which is arranged between the water flow hole 501 and the cold water inlet 503 . The controller 504 is used to receive a flow signal from the first flow sensor 505 .

[0065] like Figure 4 and Figure 5 As shown, the connecting valve 5 also includes a valve body 510, and the water flow hole 501 is arranged on a horizontal plane 511. The two ends of the horizontal plane 511 are respectively connected with inclined surfaces 512, and the two inclined surfaces 512 are respectively connected to the inner surface of the valve body 510, and the angles between the two inclined surfaces 512 and the horizontal plane 511 are both obtuse angles.

[0066] Among them, the water flow hole 501 is arranged on a horizontal plane 511, and has inclined surfaces 512 at both ends, which are obtuse angles with the horizontal plane 511. The inclined surfaces 512 are connected to the inner surface of the valve body 510. The two inclined surfaces 512 and the horizontal plane 511 block the water flow at both ends of the valve body 510 from passing through. The water flow hole 501 is arranged on the horizontal plane 511. The setting of the inclined surface 512 can effectively buffer the speed of water flow through the water flow hole 501, prevent partial water from flowing back, and increase the service life of the connecting valve 5 while improving safety.

[0067] like Figures 3 to 5 As shown, a moving passage 513 for the valve core 500 to move is provided in the connecting valve 5, and the surface of the valve core 500 has an annular groove 514, and a sealing ring 515 is sleeved on the annular groove 514, and the sealing ring 515 is sealed with the moving passage 513 on the circumference of the valve core 500. Specifically, the sealing ring 515 is an O-ring.

[0068] Among them, the valve core 500 has an annular groove 514, and the annular groove 514 is covered with a sealing ring 515, and the sealing ring 515 is sealed with the moving channel 513 on the peripheral side of the valve core 500, so that when the water flows through the connecting valve 5, it will not flow to other places through the valve core 500, thereby ensuring the stability of the connecting valve 5.

[0069] like Figures 4 to 7As shown, the steps of the preheating cycle and boosting control method with a connecting valve include: executing step 101 to determine and select to enter the preheating cycle mode, or to enter the boosting mode; the preheating cycle mode includes: executing step 102 the circulating pump 3 outputs a first flow signal; executing step 103 the first flow sensor 505 receives the first flow signal within a specified time; executing step 104 the controller 504 controls the valve core 500 to open the water flow hole 501; executing step 105 to end the preheating cycle mode; the boosting mode includes: executing step 201 the circulating pump 3 outputs a second flow signal; executing step 202 the first flow sensor 505 receives the second flow signal within a specified time; executing step 203 the controller 504 controls the valve core 500 to close the water flow hole 501; executing step 204 to end the boosting mode; executing step 205 the flow signal received by the first flow sensor 505 for a period of time is 0; executing step 206 the controller 504 controls the valve core 500 to open the water flow hole 501.

[0070] Among them, by judging and choosing to enter the preheating cycle mode, or entering the boosting mode, in the two states of entering the preheating and boosting, two-stage flow signals are output respectively to control the valve core 500 to open in the preheating cycle mode and close in the boosting mode, thereby ensuring that hot water will not be discharged when turning on the cold water, and the boosting effect is good during boosting and the safety of boosting is improved.

[0071] In this embodiment, step 101 determines and selects to enter the preheating cycle mode, or enters the boosting mode, including: determining whether there is a need to enter the preheating cycle, if so, entering the preheating cycle mode; if not, determining whether there is a need to enter the boosting mode, if there is a boosting demand, entering the boosting mode, if there is no boosting demand, maintaining the initial state.

[0072] Among them, judging and selecting to enter the preheating cycle mode, or first judging whether there is a need to enter the preheating cycle when entering the boost mode, the need for the preheating cycle can be given priority to ensure that the preheating function is processed first.

[0073] like Figure 1 As shown, the control method also includes a temperature sensor 4, which is arranged at the water outlet of the gas water heater 1. The step of determining whether there is a need to enter a preheating cycle also includes: the user clicks to enter the preheating mode, or the temperature sensor 4 detects that the water outlet temperature is lower than a preset temperature.

[0074] The preheating mode can be entered manually or automatically by clicking or detecting by the temperature sensor 4, thereby improving the degree of automation.

[0075] like Figure 1 , Figure 6 and Figure 7As shown, the control method further includes a second flow sensor 6, the second flow sensor 6 is connected to the circulation pump 3, and the second flow sensor 6 is used to detect the flow rate of the water flow of the circulation pump 3. Step 102 that the circulation pump 3 outputs the first flow signal also includes: the circulation pump 3 generates a first flow signal; the second flow sensor 6 detects the first flow signal; if the first flow signal is consistent with the set signal, then step 103 is executed, the first flow sensor 505 receives the first flow signal within the specified time, and step 104 is executed, the controller 504 controls the valve core 500 to open the water flow hole 501; if the first flow signal is inconsistent with the set signal, then the control method is terminated. Specifically, step 103 that the first flow sensor 505 receives the first flow signal within the specified time also includes: the first flow sensor 505 receives the first flow signal within the specified time as a three-flow square wave.

[0076] Among them, the second flow sensor 6 detects the first flow signal. If the first flow signal is consistent with the set signal, the controller 504 controls the valve core 500 to open the water flow hole 501; the second flow sensor 6 detects whether the flow rate of the water flow of the circulation pump 3 is consistent with the set signal to ensure stability and prevent malfunction of the preheating function. If it is inconsistent, it can be terminated in time. In this embodiment, when the gas water heater 1 has a preheating cycle demand, the preheating cycle mode is started, combustion is carried out internally for the first 30 seconds, and the water flow of the gas water heater 1 is controlled at 3L / min, and step 102 is executed, and the circulation pump 3 outputs the first flow signal, and the first flow signal is 3 times a 3-liter flow square wave. The setting of the flow square wave is convenient for detection, and the accuracy of the detection can be improved by setting the flow square wave 3 times; step 103 is executed, and the first flow sensor 505 receives the first flow signal within the specified time, and the specified time is 30S, but not limited to this; step 104 is executed, and the controller 504 controls the valve core 500 to open the water flow hole 501, and the circulation pump 3 runs at maximum power, and the gas water heater 1 burns. Through the cooperation of the circulation pump 3, the first flow sensor 505 and the controller 504, the valve core 500 is remotely controlled to open or close, and the normal operation of the preheating function is guaranteed at the same time, thereby optimizing the control process.

[0077] like Figure 6 and Figure 7 As shown, the step of ending the preheating cycle mode also includes: the user cancels entering the preheating mode, or the water outlet temperature detected by the temperature sensor 4 is greater than or equal to the preset temperature.

[0078] The preheating mode can be terminated manually or automatically by clicking or detecting by the temperature sensor 4, thereby improving the degree of automation.

[0079] like Figure 6 and Figure 7As shown, the control method further includes a second flow sensor 6, the second flow sensor 6 is connected to the circulation pump 3, and the second flow sensor 6 is used to detect the flow rate of the water flow of the circulation pump 3. The step 201 of the circulation pump 3 outputting the second flow signal includes: the circulation pump 3 generates a second flow signal; the second flow sensor 6 detects the second flow signal; if the second flow signal is consistent with the set signal, then the step 202 is executed, the first flow sensor 505 receives the second flow signal within the specified time, and the step 203 is executed when the controller 504 controls the valve core 500 to close the water flow hole 501; if the second flow signal is inconsistent with the set signal, then the method is terminated. Specifically, step 202 of the first flow sensor 505 receiving the second flow signal within the specified time includes: the first flow sensor 505 receives the second flow signal within the specified time as the flow is detected, but the three flow square waves are not detected.

[0080] Among them, the second flow sensor 6 detects the second flow signal. If the second flow signal is consistent with the set signal, the controller 504 controls the valve core 500 to close the water flow hole 501; the second flow sensor 6 detects whether the flow rate of the water flow of the circulation pump 3 is consistent with the set signal to ensure stability and prevent the boost function from malfunctioning. If it is inconsistent, it can be stopped in time. In this embodiment, the circulation pump 3 outputs the second flow signal in step 201. The second flow signal is the detected flow, but the flow is not a square wave of 3 liters three times. The flow method is simple and easy to obtain, which can effectively ensure the normal operation of the boost function. Execute step 202, the first flow sensor 505 receives the second flow signal within the specified time, and execute step 203, the controller 504 controls the valve core 500 to close the water flow hole 501, so that in the boost mode, the connecting valve 5 cannot pass water, preventing the hot water from returning to the gas water heater 1 from the connecting valve 5 and continuing to be circulated and heated, thereby improving the safety of the system; when executing step 203, the controller 504 controls the valve core 500 to close the water flow hole 501, the water can continue to flow out through the small hole 506, and the valve core 500 needs to block the water flow, so those skilled in the art can Obviously, based on the starting point of the present invention, the small hole 506 is designed to be small enough so as not to affect the function of the entire system, and the first flow sensor 505 can continue to detect a small flow, ensuring that in the boost mode, the valve core 500 can continue to close the water flow hole 501; executing step 205, the flow signal received by the first flow sensor 505 is 0 for a period of time, which is 10S in this embodiment, and can also be 15S or 20S, and the length of time is not limited to this, and then executing step 206 to control the valve core 500 to open the water flow hole 501, to prepare for the next state judgment.

[0081] In this embodiment, the termination of the preheating cycle function or the pressurizing function also includes completely stopping, or causing the circulation pump 3 to generate a signal again.

[0082] Among them, the termination is that the second flow signal is inconsistent with the set signal. Complete stopping can be detected in time to prevent affecting normal operation; and the circulation pump 3 regenerates the signal and can re-output the signal to improve automation.

[0083] The present invention also provides an electronic device, comprising a memory, a processor and a computer program stored in the memory and executable on the processor, wherein when the processor executes the computer program, any of the aforementioned preheating cycle and boost control methods with a connecting valve is implemented.

[0084] Among them, the electronic equipment can realize the circulation and boost control method with a connecting valve, so that the preheating cycle and the circulation function can operate normally respectively.

[0085] The present invention also provides a computer-readable storage medium having a computer program stored thereon, and when the computer program is executed by a processor, any of the aforementioned preheating cycle and boost control methods with a connecting valve is implemented.
