In addition, in the drawings, structures with similar or identical structures are represented by the same reference numerals.

[0025] See also Figure 1 , Figure 1 FIG. 1 is a schematic diagram of the structure of an intelligent hot water control system 100 provided in one embodiment of the present invention. Figure 1 As shown, the intelligent hot water control system 100 includes a heating water storage device, a water supply component, a cold and hot water regulating component, a control device and a plurality of temperature detection components. The heating water storage device is used to store cold water and heat the cold water to obtain hot water; one end of the water supply component is connected to the heating water storage device to provide cold water to the heating water storage device; one end of the cold and hot water regulating component is connected to the other end of the water supply component to receive the cold water provided by the water supply component, and the other end of the cold and hot water regulating component is connected to the heating water storage device to receive the hot water provided by the heating water storage device; the plurality of temperature detection components are used to respectively detect the temperatures of the cold water and the hot water to obtain the cold water temperature and the hot water temperature; the control device is used to adjust the cold water inlet and the hot water inlet of the cold and hot water regulating component according to the cold water temperature and the hot water temperature so that the water temperature of the cold and hot water regulating component is consistent with the target water temperature.

[0026] Specifically, traditional hot water control systems usually require users to manually set the target temperature, and then the system heats the water tank to the target temperature. When using the system, users adjust the water outlet temperature by adjusting the flow rate. When adjusting, users adjust manually and confirm whether the current water outlet temperature meets their needs by feeling the temperature. Therefore, multiple adjustments are required, which seriously reduces the user's comfort.

[0027] The intelligent hot water control system 100 provided by the present invention may include a heating water storage device, a water supply component, a hot and cold water adjustment component, a control device, and a plurality of temperature detection components. The heating water storage device is used to store cold water and heat the cold water to obtain hot water. The heating water storage device is connected to the water supply component, and the water supply component provides cold water. At the same time, the heating water storage device is also connected to the hot and cold water adjustment component to transport hot water to the hot and cold water adjustment component. The heating water storage device may include a water storage component and a heating external unit. The water storage component and the heating external unit are connected through a refrigerant connection component. The water storage component is used to store cold water, and the heating external unit is used to heat the water storage component to increase the water temperature of the water storage component.

[0028] The cold and hot water regulating parts are connected to the water supply part and the heating water storage device respectively, and are used to receive the cold water delivered by the water supply part on the one hand, and to receive the hot water delivered by the heating water storage device on the other hand, and mix the cold water and the hot water to neutralize the cold water temperature and the hot water temperature. The cold and hot water regulating parts can adjust the degree of connectivity with the water supply part and the degree of connectivity with the heating water storage device respectively, so as to adjust the cold water inflow and the hot water inflow. For example, when the degree of connectivity between the cold and hot water regulating parts and the water supply part is high, the cold water inflow is large, and when the degree of connectivity between the cold and hot water regulating parts and the heating water storage device is high, the hot water inflow is large. It can be understood that the degree of connectivity between the cold and hot water regulating parts and the water supply part and the degree of connectivity between the cold and hot water regulating parts and the heating water storage device are independently adjusted, that is, the degree of connectivity between the cold and hot water regulating parts and the water supply part and the degree of connectivity between the cold and hot water regulating parts and the heating water storage device can be a higher degree of connectivity or a lower degree of connectivity, or a high degree and a low degree of connectivity. The water outlet of the hot and cold water regulating member is connected to the water outlet pipe, and the water after the neutralization temperature can be provided to the user for bathing through the water outlet pipe.

[0029] The temperature detection element is used to detect the water temperature at different locations in the system. For example, the water temperature of the water supply element can be detected to obtain the cold water temperature, and the water temperature of the heating water storage device can be detected to obtain the hot water temperature. The temperature detection element can be a temperature sensor, which can be set according to the water temperature to be monitored. For example, the temperature detection sensor can be set at the water supply element to detect the cold water temperature, and at the heating water storage device to detect the hot water temperature.

[0030] The control device can adjust the cold water inlet and hot water inlet of the hot and cold water regulating parts according to the preset algorithm, the cold water temperature and the hot water temperature, thereby adjusting the water temperature of the hot and cold water regulating parts, that is, the outlet water temperature, so that the outlet water temperature is consistent with the target water temperature. Among them, the target water temperature is the water temperature set by the user, and the outlet water temperature is the water temperature in the outlet pipe. When using, the user only needs to set the target temperature, and the outlet water temperature can be consistent with the target temperature without manually adjusting the flow rate, which improves the user's comfort.

[0031] As a further embodiment, it also includes a pipeline assembly, which is used to connect the heating water storage device with the water supply component, the water supply component with the hot and cold water adjustment component, and the heating water storage device with the hot and cold water adjustment component.

[0032] The pipeline assembly may include a plurality of water pipes, and different water pipes are used to connect different devices. For example, the water supply component is connected to the heating water storage device through the pipeline assembly, the heating water storage device is connected to the hot and cold water regulating component through the pipeline assembly, and the water supply component is connected to the hot and cold water regulating component through the pipeline assembly. When in use, the hot water in the heating water storage device can enter the hot and cold water regulating component through the pipeline assembly, and at the same time, the cold water in the water supply component can also enter the hot and cold water regulating component through the pipeline assembly, so that the hot and cold water regulating component can neutralize the cold water temperature and the hot water temperature.

[0033] As a further embodiment, the pipeline assembly includes a first connecting pipe, a second connecting pipe and a third connecting pipe; the first connecting pipe is used to connect the heating water storage device with the water supply component, the second connecting pipe is used to connect the water supply component with the cold and hot water regulating component, and the third connecting pipe is used to connect the heating water storage device with the cold and hot water regulating component.

[0034] Among them, the pipeline assembly may include a first connecting pipe, a second connecting pipe and a third connecting pipe, the first connecting pipe is respectively connected to the heating water storage device and the water supply component, and the cold water in the water supply component enters the heating water storage device through the first connecting pipe, so that the heating water storage device heats the cold water.

[0035] The second connecting pipe is connected to the water supply component and the cold and hot water regulating component respectively, and the cold water in the water supply component enters the cold and hot water regulating component through the second connecting pipe.

[0036] The third connecting pipe is used to connect the heating water storage device and the cold and hot water regulating member respectively, and the hot water in the heating water storage device enters the cold and hot water regulating member through the third connecting pipe.

[0037] The hot and cold water regulating member can adjust the degree of connection with the second connecting pipe and the third connecting pipe respectively, so as to adjust the cold water inflow and the hot water inflow respectively. It can be understood that the hot and cold water regulating member can be an intelligent mixing valve, which is controlled by the control device, and the control device can adjust the opening degree to adjust the degree of connection.

[0038] As a further embodiment, the multiple temperature detecting components include a first temperature detecting component and a second temperature detecting component; the first temperature detecting component is arranged on the second connecting pipe, and is used to detect the temperature of cold water in the second connecting pipe to obtain the cold water temperature; the second temperature detecting component is arranged on the third connecting pipe, and is used to detect the temperature of hot water in the third connecting pipe to obtain the hot water temperature.

[0039] The plurality of temperature detection components may include a first temperature detection component and a second temperature detection component. The first temperature detection component may be disposed at the second connecting pipe near the cold and hot water adjusting component to detect the cold water temperature, and the second temperature detection component may be disposed at the third connecting pipe near the cold and hot water adjusting component to detect the hot water temperature. The cold water temperature detected by the first temperature detection component and the hot water temperature detected by the second temperature detection component may both be sent to the control device. For example, the first temperature detection component and the second temperature detection component may both be wirelessly connected to the control device, and the cold water temperature data and the hot water temperature data may be transmitted to the control device in the form of wireless transmission, so that the control device can adjust the cold water inflow and the hot water inflow.

[0040] As a further embodiment, the multiple temperature detection components also include a third temperature sensor, a fourth temperature sensor and a fifth temperature sensor; the third temperature sensor is used to detect the temperature of the heating water storage device, the fourth temperature sensor is used to detect the outdoor temperature, and the fifth temperature sensor is used to detect the outlet water temperature of the hot and cold water regulating component.

[0041] Among them, the third temperature sensor can be arranged at the heating water storage device, for example, arranged in the water storage part, for detecting the water temperature in the water storage part, the fourth temperature sensor can be arranged at the heating external unit, for detecting the outdoor temperature, the fifth temperature sensor can be arranged at the water outlet pipe, for detecting the outlet water temperature, and the data detected by the third temperature sensor, the fourth temperature sensor and the fifth temperature sensor can be transmitted to the control device in the form of wireless transmission, so as to facilitate the control device to make adjustments. For example, when the outdoor temperature is high, the cold water inlet can be appropriately increased to reduce the outlet water temperature, or when the water temperature in the water storage part does not reach the preset heating temperature, the heating power of the heating external unit can be increased to quickly heat the water temperature in the water storage part to the preset heating temperature, or when the outlet water temperature is inconsistent with the target temperature, the cold water inlet and the hot water inlet can be adjusted so that the outlet water temperature is consistent with the target temperature.

[0042] See also Figure 2 The present invention further provides a control method, which is used to control the intelligent hot water control system described in any one of the above embodiments, and the control method includes S110-S120.

[0043] S110, controlled by a start instruction for starting the intelligent hot water control system, obtaining a target temperature, an outlet water temperature, a real-time cold water parameter, and a real-time hot water parameter.

[0044] In the embodiment of the present invention, the start instruction may be a start instruction of the intelligent hot water system, that is, when the user turns on the system, the target temperature, the outlet water temperature, the real-time cold water parameter and the real-time hot water parameter are obtained. The target temperature is the outlet water temperature set by the user, the outlet water temperature is the real-time water temperature in the outlet pipe, the real-time hot water parameter is a parameter related to hot water, such as the hot water temperature and the hot water inflow, and the real-time cold water temperature is a parameter related to cold water, such as the cold water temperature and the cold water inflow.

[0045] S120: adjusting the real-time cold water parameter and the real-time hot water parameter based on the difference between the outlet water temperature and the target temperature so that the outlet water temperature is consistent with the target temperature.

[0046] In an embodiment of the present invention, after obtaining the target temperature, the outlet water temperature, the real-time cold water parameters and the real-time hot water parameters, the difference between the target temperature and the outlet water temperature is confirmed, and the difference can be the size relationship between the target temperature and the outlet water temperature. Then, based on the difference between the target temperature and the outlet water temperature, the real-time cold water parameters and the real-time hot water parameters are adjusted to make the outlet water temperature consistent with the target temperature.

[0047] See also Figure 3 In some embodiments, such as in an embodiment of the present invention, the real-time cold water parameters include cold water temperature and cold water flow, the real-time hot water parameters include hot water temperature and hot water flow, and the step S120 also includes steps S121-S123.

[0048] S121, confirming the difference between the outlet water temperature and the target temperature;

[0049] S122, if the outlet water temperature is less than or equal to the target temperature, increasing the hot water flow rate and / or reducing the cold water flow rate;

[0050] S123: If the outlet water temperature is greater than the target temperature, reducing the hot water flow rate and / or increasing the cold water flow rate.

[0051] In the embodiment of the present invention, the real-time cold water parameter may include the cold water temperature and the cold water flow, and the real-time hot water parameter may include the hot water temperature and the hot water flow. For example, in an intelligent hot water control system, the cold water temperature may be obtained by a first temperature detection component, the hot water temperature may be obtained by a second temperature detection component, and the cold and hot water adjustment component may detect the cold water flow and the hot water flow, and adjust the cold water flow and the hot water flow.

[0052] When the outlet water temperature is less than or equal to the target temperature, the hot water flow rate can be increased or the cold water flow rate can be reduced. When the outlet water temperature is greater than the target temperature, the hot water flow rate can be reduced or the cold water flow rate can be increased. It can be understood that the hot water temperature and the cold water temperature are generally fixed. For example, the user can set the hot water temperature to 60°C and the cold water temperature to 20°C. In most cases, the hot water temperature is constant at 60°C and the cold water temperature is constant at 20°C. Affected by the environment, the hot water temperature and the cold water temperature can increase or decrease to a certain extent. Before the user makes an adjustment, there will be no significant change. At this time, only the hot water flow rate and the cold water flow rate can be adjusted to adjust the outlet water temperature. Specifically, the outlet water temperature can be obtained by formula (1):

[0053]

[0054] Among them, T u is the outlet water temperature, T c is the cold water temperature, T h is the hot water temperature, F c is the cold water flow rate, F h is the hot water flow rate. When the cold water temperature and the hot water temperature remain unchanged, the cold water flow rate or the hot water flow rate can be kept constant, and then the hot water flow rate or the cold water flow rate can be adjusted to adjust the outlet water temperature. In addition, when adjusting the outlet water temperature, the PID (Proportional Integral Derivative Control) control algorithm can also be used to achieve precise adjustment. The control module outputs a corresponding control signal to change the ratio of cold and hot water according to the difference between the outlet water temperature and the target temperature, so that the outlet water temperature quickly matches the target temperature.

[0055] See also Figure 4 In some embodiments, such as in an embodiment of the present invention, the control method comprises steps S130-S150.

[0056] S130, confirming the difference between the real-time hot water temperature and the set hot water temperature;

[0057] S140, if the real-time hot water temperature is less than or equal to the set hot water temperature, increasing the hot water flow rate and / or reducing the cold water flow rate;

[0058] S150: If the real-time hot water temperature is greater than the set hot water temperature, the hot water flow rate is reduced and / or the cold water flow rate is increased.

[0059] In the embodiment of the present invention, both the real-time hot water temperature and the real-time cold water temperature may fluctuate, and the main reasons for the fluctuations of the two are changes in ambient temperature, temperature loss during transmission, and the like. Therefore, the relationship between the real-time hot water temperature and the set hot water temperature and the relationship between the real-time cold water temperature and the set cold water temperature can be confirmed. For example, when the real-time hot water temperature is less than or equal to the set hot water temperature, the hot water flow rate is increased and / or the cold water flow rate is reduced. When the real-time hot water temperature is greater than the set hot water temperature, the hot water flow rate can be reduced and / or the cold water flow rate is increased to maintain the outlet water temperature consistent with the target temperature. Similarly, when the real-time cold water temperature is less than or equal to the set cold water temperature, the cold water flow rate can be increased and / or the hot water flow rate can be reduced. When the real-time cold water temperature is greater than the set cold water temperature, the cold water flow rate can be reduced and / or the hot water flow rate can be increased.

[0060] See also Figure 5 In some embodiments, such as in an embodiment of the present invention, the control method comprises steps S160-S170.

[0061] S160, controlled by the module selection instruction, confirming the currently selected preset temperature module;

[0062] S170: confirming the ambient temperature and a preset target temperature matching the ambient temperature according to the preset temperature module, and setting the preset target temperature as the target temperature.

[0063] In an embodiment of the present invention, when a user uses the system for the first time, he or she can create a preset temperature module, which is used to record the user's preferred temperature. The user does not need to adjust the temperature again the next time he or she uses the system, but can select the corresponding preset temperature module. For example, for two users, user A and user B, user A can create a preset temperature module, which includes a target temperature and an ambient temperature, such as a target temperature of 38°C and an ambient temperature of 20°C. Similarly, user B can create a preset temperature module, which has a target temperature of 40°C and an ambient temperature of 20°C. Then, when user A uses the system next time, he or she can select the corresponding preset temperature module to adjust the target temperature of the system to 40°C.

[0064] See also Figure 6 In some embodiments, such as in an embodiment of the present invention, the control method comprises steps S180-S190.

[0065] S180, confirming whether the ambient temperature changes;

[0066] S190: If the ambient temperature changes, confirm the new ambient temperature and adjust the preset target temperature according to the new ambient temperature.

[0067] In an embodiment of the present invention, the ambient temperature may include outdoor temperature and indoor temperature. When the outdoor temperature or indoor temperature changes, it is deemed that the ambient temperature has changed, and the preset target temperature can be adjusted so that the outlet water temperature is more in line with the user's needs. In addition, in addition to the ambient temperature, the ambient humidity can also be used as a parameter for adjusting the preset target temperature. For example, the target temperature set by user A in the morning is 40°C, and the outdoor temperature is 20°C, the indoor temperature is 22°C, and the indoor humidity is 50%. If the weather changes one day, causing the outdoor temperature to drop to 15°C, the indoor temperature to drop to 20°C, and the indoor humidity to rise to 60%, the system can predict the new target temperature of user A to be 42°C through machine learning, and then adjust the cold water inlet and hot water inlet to make the outlet water temperature reach 42°C.

[0068] In addition, the preset temperature module can also be automatically updated through machine learning. For example, the target temperature of user A in the morning is 40°C and the ambient temperature is 20°C, and the target temperature of user A in the evening is 35°C and the ambient temperature is 25°C. If one day when user A uses hot water in the morning, the actual temperature is 42°C and the ambient temperature is 18°C, and when using hot water in the evening, the actual temperature is 34°C and the ambient temperature is 28°C, the system will recalculate the user's target temperature, that is, 40°C + (42°C - 40°C) * temperature weight = 40.5°C, 35°C + (34°C - 35°C) * temperature weight = 34.8°C, and then update the target temperature in the preset temperature module in the morning to 40.5°C, and update the target temperature in the preset temperature module in the evening to 34.8°C.

[0069] The intelligent hot water control system and control method disclosed in the present invention can automatically adjust the outlet water temperature according to the target temperature, the outlet water temperature, the real-time hot water parameters and the real-time cold water parameters, so that the outlet water temperature is consistent with the target temperature, thereby improving the user's comfort during use.

[0070] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
