[0042] The present application will be further described below by way of examples, but the present application is not limited in the scope of the examples.

[0043] Embodiment 1

[0044] The present embodiment provides a constant temperature control method of an intelligent water heating device, as shown in the figure, the constant temperature control method comprises: Figure 1 S11, when the current water flow of the intelligent water heating device is detected to be greater than the set flow threshold, the current load value is calculated;

[0045] S11, when the current water flow of the intelligent water heating device is detected to be greater than the set flow threshold, the current load value is calculated;

[0046] S121, if the current load value is less than the set load threshold and the current water flow is less than the set flow threshold, the intelligent water heating device is delayed for a first set period of time before being turned off;

[0047] S122, if the current load value is not less than the set load threshold value and the current water flow is less than the set flow threshold value, the intelligent water heating device is switched from the high combustion section to the low combustion section and is turned off after a second set period of time;

[0048] S13, after the intelligent water heating device is in the power standby state, if the current water flow is greater than the set flow threshold value, it is judged whether the intelligent water heating device is greater than a third set period of time from the last shutdown time; if greater than the third set period of time, step S141 is executed, and if not greater than the third set period of time, step S142 is executed;

[0049] S141, the intelligent water heating device is controlled to start the first heating operation;

[0050] S142, the intelligent water heating device is controlled to start the second heating operation.

[0051] In the embodiment, the intelligent water heating device includes a water heater, a wall-mounted stove, etc. When the intelligent water heating device is in a water flow working state, it is judged whether the current water flow is greater than a set flow threshold value. If not, the water flow working state of the intelligent water heating device is continuously monitored. If yes, the current load value of the intelligent water heating device is calculated. If the current load is less than the set load threshold value, it is continuously judged whether the current water flow is greater than or equal to the set flow threshold value. If yes, the intelligent water heating device in the water flow working state is continuously monitored. When the current water flow is less than the set flow threshold value, the intelligent water heating device is turned off after a first set period of time or is switched from the high combustion section to the low combustion section and is turned off after a second set period of time. The calculation formula of the first set period of time is t1= current load value*X1+Y1, and the calculation formula of the second set period of time is t2= current load value*X2+Y2, wherein the values of X1, X2, Y1 and Y2 can be adaptively adjusted according to different types of intelligent water heating devices. When the intelligent water heating device is shut down, the temperature of the water in the pipeline is increased by a certain number of degrees Celsius by delaying the shutdown, and when the intelligent water heating device is turned on again, the heat is transferred to the low-temperature water through the pipeline to achieve the constant temperature performance.

[0052] After the intelligent water heating device is in the power standby state, if the current water flow is greater than the set flow threshold value, it is continuously judged that the intelligent water heating device is greater than a third set period of time from the last shutdown time, the fan is started, the pre-cleaning is performed for a fourth set period of time and is ignited, it is continuously detected that the intelligent water heating device is not greater than the third set period of time from the last shutdown time, the pre-cleaning is cancelled, and the fan is started and directly ignited after being started. When the time interval between two times of starting the intelligent water heating device is less than the third set period of time, it is determined that the intelligent water heating device is turned on after being shut down in the middle. The intelligent water heating device is directly ignited after being started twice and the power of the fast heating is pulled up to reduce the temperature drop.

[0053] In an embodiment, step S11 specifically comprises:

[0054] S111, obtaining the outlet water temperature and the inlet water temperature;

[0055] S112, calculating the current load value according to the outlet water temperature, the inlet water temperature and the current water flow.

[0056] In the embodiment, the current load value is M=K1(outlet water temperature-inlet water temperature)*water flow / 25, K1 represents a set coefficient, because the outlet water temperature remains constant, the inlet water temperature and the water flow change with the running time of the intelligent water heating device, causing the current load value to change constantly. This way calculates the current load value in real time based on the inlet water temperature and the water flow, to improve the accuracy of the subsequent start of the flameout operation.

[0057] In an embodiment, step S141 specifically comprises:

[0058] controlling the intelligent water heating device to start the fan and ignite and heat at a low heating power after pre-cleaning according to a fourth set time period.

[0059] Step S142 specifically comprises:

[0060] controlling the intelligent water heating device to start the fan and ignite and heat at a high heating power.

[0061] In the embodiment, when the intelligent water heating device is controlled to ignite and heat at a low heating power, the low heating power is calculated from the first proportional coefficient, the target temperature, the inlet water temperature and the water flow; when the intelligent water heating device is controlled to ignite and heat at a high heating power, the high heating power is calculated from the second proportional coefficient, the target temperature, the inlet water temperature and the water flow. This way improves the accuracy of the calculation of the low heating power and the high heating power, improves the thermostatic performance of the intelligent water heating device, and reduces the cost of installing other devices to maintain the thermostatic effect. By detecting the time difference between the two times when the intelligent water heating device is turned on and off, it is determined whether the water is turned off during bathing. If the water stop time is less than a third set time period, it is determined that the water is turned off during bathing, the pre-cleaning is cancelled and the ignition is directly started, the heating speed is improved to reduce the temperature drop; if the water stop time exceeds the third set time period, it is determined that the water is turned off during non-bathing, and the pre-cleaning is performed. Because the time between the two times is too long, if it is not cleaned, it is easy to cause the parts to leak and cause the ignition to explode.

[0062] The embodiment provides a thermostatic control method of an intelligent water heating device. During the shutdown period of the intelligent water heating device, the flameout is delayed to promote the increase of the water temperature in the pipeline, and different heating operations are performed when the water is turned on again to make the pipeline uniform, so that high heat is transferred to low temperature water to achieve a thermostatic effect and improve user experience.

[0063] Embodiment 2

[0064] The embodiment provides a constant temperature control system of an intelligent water heating device, as shown in the figure. Figure 2 The constant temperature control system comprises:

[0065] The computing module 210 is configured to calculate a current load value when it is detected that the current water flow of the intelligent water heating device is greater than a set flow threshold value.

[0066] The first extinguishing module 221 is configured to delay the intelligent water heating device to extinguish after a first set time period if the current load value is less than a set load threshold value and the current water flow is less than the set flow threshold value.

[0067] The second extinguishing module 222 is configured to switch the intelligent water heating device from a high combustion section to a low combustion section and then delay the intelligent water heating device to extinguish after a second set time period if the current load value is not less than the set load threshold value and the current water flow is less than the set flow threshold value.

[0068] The judging module 230 is configured to judge whether the intelligent water heating device is greater than a third set time period from the last shutdown time when the current water flow is greater than the set flow threshold value after the intelligent water heating device is in a power standby state; if greater than the third set time period, the first heating module 241 is called, and if not greater than the third set time period, the second heating module 242 is called.

[0069] The first heating module 241 is configured to control the intelligent water heating device to perform a first heating operation.

[0070] The second heating module 242 is configured to control the intelligent water heating device to perform a second heating operation.

[0071] In the embodiment, when the intelligent water heating device is in a water flow working state, it is judged whether the current water flow is greater than a set flow threshold value; if not, the water flow working state of the intelligent water heating device is continuously monitored, and if yes, a current load value of the intelligent water heating device is calculated. If the current load is less than a set load threshold value, it is continuously judged whether the current water flow is greater than or equal to the set flow threshold value; if yes, the water flow working state of the intelligent water heating device is continuously monitored. When the current water flow is less than the set flow threshold value, the intelligent water heating device is delayed to extinguish after a first set time period or the intelligent water heating device is switched from a high combustion section to a low combustion section and then delayed to extinguish after a second set time period. The calculation formula of the first set time period is t1=the current load value*X1+Y1, and the calculation formula of the second set time period is t2=the current load value*X2+Y2, wherein the values of X1, X2, Y1 and Y2 can be adaptively adjusted according to different kinds of intelligent water heating devices. When the intelligent water heating device is shut down, the temperature of the water in the pipeline is increased by a certain number of degrees Celsius by delaying the extinguishing, and when the intelligent water heating device is started again, the heat is transferred to the low-temperature water through the pipeline to achieve the constant temperature performance.

[0072] After the smart water heater is powered on and in standby mode, if the current water flow rate is detected to be greater than the set flow rate threshold, and it is determined that the time since the last shutdown is greater than the third set time period, the fan is started, pre-cleaning is performed during the fourth set time period, and ignition is initiated. If the time since the last shutdown is detected to be less than the third set time period, pre-cleaning is cancelled, and ignition is initiated directly after the fan starts. If the time interval between two startups of the smart water heater is less than the third set time period, it is determined that the smart water heater has been shut off and then restarted. Upon the second startup, the smart water heater is immediately ignited after the water is turned on, and the power of rapid heating is increased to reduce temperature drop.

[0073] In one embodiment, such as Figure 3 As shown, the calculation module 210 includes:

[0074] Acquisition unit 211 is used to acquire the outlet water temperature and the inlet water temperature;

[0075] The calculation unit 212 is used to calculate the current load value based on the outlet water temperature, inlet water temperature and current water flow rate.

[0076] In this embodiment, the calculation formula for the current load value determined by the calculation unit 212 is: M = K1(outlet water temperature - inlet water temperature) * water flow rate / 25, where K1 represents a set coefficient. Because the outlet water temperature remains constant, while the inlet water temperature and water flow rate change with the operating time of the intelligent hot water equipment, the current load value continuously changes. This method calculates the current load value in real time based on the inlet water temperature and water flow rate to improve the accuracy of subsequent start-up operations after shutdown.

[0077] In one embodiment, the first heating module 241 is specifically used for:

[0078] Control the intelligent hot water equipment to start the fan and perform pre-cleaning followed by low-power ignition heating according to the fourth set time period.

[0079] The second heating module 242 is specifically used for:

[0080] Control the intelligent hot water equipment to start the fan and ignite for high-power heating.

[0081] In this embodiment, when the first heating module 241 controls the intelligent water heating device to ignite and heat at a low heating power, the low heating power is calculated by the first proportional coefficient, the target temperature, the inlet water temperature and the water flow; when the second heating module 242 controls the intelligent water heating device to ignite and heat at a high heating power, the high heating power is calculated by the second proportional coefficient, the target temperature, the inlet water temperature and the water flow. This mode improves the accuracy of the calculation of the low heating power and the high heating power, improves the constant temperature performance of the intelligent water heating device, and reduces the cost of other devices required to maintain the constant temperature effect. By detecting the time difference between the two times of turning on and off the water of the intelligent water heating device, it is determined whether it is the water-off in the bathing process. If the water-off time is less than a third set period, it is determined that the water-off is in the bathing process, the pre-cleaning is cancelled and the ignition is directly ignited to improve the heating speed and reduce the temperature drop; if the water-off time exceeds the third set period, it is determined that the water-off is not in the bathing process, and the pre-cleaning is performed. Because the time between the two times is too long, if the cleaning is not performed, the parts may be prone to leakage, which may cause ignition explosion problem.

[0082] The intelligent water heating device in this embodiment can be controlled by a voice module, which is installed with a controller, a voice receiving module and a voice analysis module. The voice receiving module receives the instructions of the user, and the voice analysis module analyzes the instructions. According to the analyzed instructions, the controller controls the intelligent water heating device to perform corresponding operations, so as to realize intelligent control in the intelligent water heating device and improve the user experience.

[0083] The intelligent water heating device in this embodiment can also use other intelligent interaction functions, such as gesture interaction and fingerprint recognition. The specific settings or adjustments can be made according to actual needs to further improve the intelligent degree of the intelligent water heating device and provide better experience for the user.

[0084] This embodiment provides a constant temperature control system of an intelligent water heating device. During the shutdown period of the intelligent water heating device, the first or second extinguishing module promotes the increase of the water temperature in the pipeline by delayed extinguishing, and the first or second heating module makes the pipeline uniform by different heating operations when the water is turned on again, so as to transfer high heat to low temperature water to achieve the constant temperature effect and improve the user experience.
