Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric wall-hanging stoves, in particular to a control method and system of an electric wall-hanging stove with a water distributor. BACKGROUND

[0002] An electric wall-hanging stove, also known as an electric heating wall-hanging stove, is a heating device that uses electricity as the main energy source. It converts electrical energy into heat energy through built-in heating pipes or advanced electromagnetic induction technology, thereby providing a stable heat source for home heating systems and daily life hot water. In modern home heating solutions, electric wall-hanging stoves are often used with water distributors to form a complete integrated heating system, which can flexibly achieve whole-house radiator heating or floor heating to meet the heating needs of different users.

[0003] However, most current electric wall-hanging stove products are still in the basic control stage and can only operate according to the user's preset power parameters, lacking the ability to dynamically adjust according to indoor and outdoor temperature changes. This technical limitation brings many problems in practical application: for example, in a floor heating environment, if the user has laid wooden floors, too high a heating temperature can cause the wooden material to deform and crack due to continuous heating; and if the temperature is set too low, it cannot maintain a comfortable indoor temperature in cold seasons, especially affecting the living experience of the elderly and children. In addition, the outdoor temperature usually drops significantly at night, and the indoor heat load changes accordingly. The existing equipment is difficult to achieve real-time response and power adaptive adjustment, resulting in a decline in heating effect in the late night, affecting user sleep comfort, and also causing low efficiency of electric energy utilization. SUMMARY

[0004] To overcome the above-mentioned defects, the present application aims to provide a control method and system of an electric wall-hanging stove with a water distributor to adapt to the automatic control of different types of electric wall-hanging stoves and meet the heating needs of users.

[0005] To achieve this purpose, the present application adopts the following technical solution: a control method of an electric wall-hanging stove with a water distributor, comprising the following steps: Step S1: in response to the type of electric wall-hanging stove, confirming the obtained adjustment parameters; Step S2: periodically obtaining the adjustment parameters; in response to the judgment of the adjustment parameters, determining whether the current electric wall-hanging stove meets the functional requirements, if yes, not adjusting the electric wall-hanging stove, if not, confirming the required control equipment to be modified through the type of electric wall-hanging stove and the adjustment parameters; Step S3: adjusting the control equipment based on the adjustment parameters, repeating step S2 until the electric wall-hanging stove is turned off.

[0006] Preferably, the electric wall-hanging stove includes a first type, a second type, and a third type; The first type is that the water distributor only includes a return water distribution pipe and a water outlet distribution pipe, and the return water distribution pipe and the water outlet distribution pipe are separately connected to the heater. The second type is that the water distributor includes a return water distribution pipe, a water outlet distribution pipe and a coupling pipe, the coupling pipe is connected to the return water distribution pipe and the water outlet distribution pipe, the return water distribution pipe and the water outlet distribution pipe are separately connected to the heater, and the return water distribution pipe and the water outlet distribution pipe are respectively provided with a first water pump and a second water pump. The third type is that the water distributor includes a return water distribution pipe, a water outlet distribution pipe and a control valve, the return water distribution pipe is embedded in the water outlet distribution pipe, the control valve is arranged on the return water distribution pipe, the control valve is used for controlling the communication state of the return water distribution pipe and the water outlet distribution pipe, and the return water distribution pipe and the water outlet distribution pipe are separately connected to the heater.

[0007] Preferably, the step S2 is as follows: When the type of the electric wall-hanging stove is the first type, the adjustment parameter is the return water temperature, and the control device is the heater. It is judged whether the return water temperature is in the temperature range, if the return water temperature is in the temperature range, the power of the heater is not modified, and if the return water temperature is not in the temperature range, a first operation is performed.

[0008] Preferably, the step S2 is as follows: When the type of the electric wall-hanging stove is the second type, the adjustment parameter is the return water temperature, and the control device is the heater, the first water pump and the second water pump. It is judged whether the return water temperature is in the temperature range, if the return water temperature is in the temperature range, the power of the heater is not modified, and if the return water temperature is not in the temperature range, it is judged whether the return water temperature is higher than the temperature range, if the return water temperature is higher than the temperature range, the power of the first water pump and the second water pump is adjusted based on the return water temperature, if the return water temperature is lower than the temperature range, the first operation is performed.

[0009] Preferably, the step S2 is as follows: when the type of the electric wall-hanging stove is the third type, the adjustment parameter is the return water temperature and the water outlet temperature, and the control device is the heater and the control valve. It is judged whether the return water temperature is in the temperature range, if the return water temperature is in the temperature range, the power of the heater is not modified, and if the return water temperature is not in the temperature range, it is judged whether the return water temperature is lower than the temperature range, if the return water temperature is lower than the temperature range, it is judged whether the water outlet temperature is lower than a temperature threshold, if the water outlet temperature is lower than the temperature threshold, the control valve is controlled to be opened based on a third difference between the temperature threshold and the water outlet temperature, if the water outlet temperature is not lower than the temperature threshold, the first operation is performed, and if the return water temperature is higher than the temperature range, the first operation is performed.

[0010] Preferably, the first operation is: Based on the current return water temperature and the outlet water temperature, the difference between the two is obtained as the first difference. The heater is then adjusted with the first power and run for a preset time. The difference between the return water temperature and the outlet water temperature is obtained again as the second difference value. Based on the second difference and the first difference, obtain the heating parameters; The heating power of the heater is determined by the heating parameters, the current return water temperature, and the temperature range, and then the heating power of the heater is adjusted.

[0011] Preferably, the power of the first and second water pumps is adjusted based on the return water temperature as follows: The difference between the return water temperature and the upper limit of the temperature range is obtained as the fourth difference, and the target pressure in the coupling pipe is obtained through the fourth difference. The pressure integral term is obtained based on the target pressure; The power difference between the first and second water pumps is obtained by replacing the trained proportional-integral control integral term with the pressure integral term. The formula for obtaining the power difference is as follows: determine whether the power difference is greater than the power threshold. If it is greater, the first water pump is turned on at the minimum power and the second water pump is turned on at the maximum power. If it is less, adjust the power of the first water pump and the second water pump based on the power difference so that the power difference between the first water pump and the second water pump meets the power difference.

If it does, no adjustment is made to the electric wall-hung boiler. If it does not, the control equipment that needs to be modified is determined based on the type of electric wall-hung boiler and the adjustment parameters. The periodic control module adjusts the control equipment based on the adjustment parameters, repeating step S2 until the electric wall-hung boiler is turned off.

[0013] One of the above technical solutions has the following advantages or beneficial effects: The present invention adjusts the corresponding control equipment by combining the equipment type and parameters, and repeatedly executes the monitoring and adjustment process to form a continuously optimized feedback mechanism, so that the electric wall-hung boiler can dynamically adapt to environmental changes, improve energy utilization efficiency while ensuring heating comfort, and ultimately maintain efficient, safe and stable heat output throughout the entire operation of the equipment.

[0020] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] In the description of embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of embodiments of the present invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] like Figures 1-5 As shown, a control method for an electric wall-hung boiler with a water distributor includes the following steps: Step S1: In response to the type of electric wall-hung boiler, confirm the obtained adjustment parameters; Step S2: Periodically acquire the adjustment parameters; in response to the judgment of the adjustment parameters, determine whether the current electric wall-hung boiler meets the functional requirements. If it does, no adjustment is made to the electric wall-hung boiler. If it does not, confirm the control equipment that needs to be modified based on the type of electric wall-hung boiler and the adjustment parameters. Step S3: Adjust the control device based on the adjustment parameters, and repeat step S2 until the electric wall-hung boiler is turned off.

[0024] In order to better realize the intelligent control of electric wall-hung boilers, the first step in this invention is to determine the type of electric wall-hung boiler. This is because after the installation of the water manifold, there are different types of water manifolds. Different types of water manifolds have different operating characteristics and controllable variables. Therefore, it is necessary to first identify the type of electric wall-hung boiler before determining the type of adjustment parameters to be obtained.

[0025] Then, by periodically acquiring parameters and judging whether functional requirements are met, the purpose is to monitor the system status in real time. For example, in scenarios where nighttime temperature fluctuates or floor materials are sensitive to temperature, it can promptly identify whether the current output matches the heating demand. This effectively avoids the problems of wood deformation or insufficient room temperature caused by fixed power output of traditional equipment. When functional requirements are not met (such as heat preservation requirements), the corresponding control equipment is adjusted in combination with the equipment type and parameters, and the monitoring and adjustment process is repeated to form a continuous optimization feedback mechanism. This enables the electric wall-hung boiler to dynamically adapt to environmental changes, improve energy utilization efficiency while ensuring heating comfort, and ultimately maintain efficient, safe and stable heating output throughout the entire operation of the equipment.

[0026] Preferably, the electric wall-hung boiler includes a first type, a second type, and a third type; The first type is a water distributor that only includes a return water pipe 1 and an outlet water pipe 2, with the return water pipe 1 and the outlet water pipe 2 separately connected to a heater 3; such as Figure 2 The cold water from the multiple water pipes shown flows into the return water pipe 1, and then flows to the connected heater 3 for heating. After heating, hot water is output to the underfloor heating or heating system through the return water pipe 1. This is a basic electric wall-hung boiler with a water distributor.

[0027] The second type is a water distributor including a return water pipe 1, an outlet water pipe 2 and a coupling pipe 4. The coupling pipe 4 connects the return water pipe 1 and the outlet water pipe 2. The return water pipe 1 and the outlet water pipe 2 are separately connected to the heater 3. The return water pipe 1 and the outlet water pipe 2 are respectively equipped with a first water pump 5 and a second water pump 6. like Figure 3As shown, to address the issue of excessively high temperatures, the second type of electric wall-hung boiler, compared to the first type, heats the coupling pipe 4 and adds an additional first water pump 5 and a second water pump 6. When the output water temperature is too high, it is necessary to control the frequency of the first water pump 5 and the second water pump 6 to adjust the water pressure inside the electric wall-hung boiler, allowing the cold water returning from the return water pipe 1 to enter the outlet water pipe 2, thereby reducing the output water temperature.

[0028] The third type is a water distributor including a return water pipe 1, an outlet water pipe 2, and a control valve 7. The return water pipe 1 is embedded in the outlet water pipe 2, and the control valve 7 is set on the return water pipe 1. The control valve 7 is used to control the connection state between the return water pipe 1 and the outlet water pipe 2. The return water pipe 1 and the outlet water pipe 2 are individually connected to the heater 3.

[0029] Because some heaters 3 have insufficient power, the output water temperature is not high enough. Figure 4 As shown, the third type, relative to the first type, involves embedding the return water pipe inside the outlet water pipe 2, and a control valve 7 is installed inside the return water pipe. When the control valve 7 is opened, the hot water from the outlet water pipe 2 will re-enter the heater 3 through the return water pipe 1 for heating, thereby meeting the heating demand.

[0030] Preferably, step S2 is as follows: When the electric wall-hung boiler is of type 1, the adjustment parameter is the return water temperature, and the control device is the heater; Determine whether the return water temperature is within the temperature range. If the return water temperature is within the temperature range, do not modify the heater power. If the return water temperature is not within the range, execute the first operation.

[0031] The return water temperature is the temperature of the water after heating. By detecting whether the return water temperature is within the specified temperature range, it can be determined whether the current outlet water temperature meets the functional requirements. This temperature range is set by the user's input temperature, and each input temperature has a corresponding temperature range. If the return water temperature is within the specified range, it means that the current heating requirement is met. If the return water temperature is outside the specified range, it means that the current outlet water temperature may be too high or too low, requiring the first operation to modify the heater power to meet the user's heating needs.

[0032] Preferably, step S2 is as follows: When the electric wall-hung boiler is of type 2, the adjustment parameter is the return water temperature, and the control equipment is the heater, the first water pump and the second water pump; Determine whether the return water temperature is within the temperature range. If the return water temperature is within the temperature range, do not modify the power of the heater. If the return water temperature is not within the temperature range, determine whether the return water temperature is higher than the temperature range. If the return water temperature is higher than the temperature range, adjust the power of the first water pump and the second water pump based on the return water temperature. If the return water temperature is lower than the temperature range, execute the first operation.

[0033] Because a coupling pipe and a first water pump and a second water pump are installed, the control equipment consists of a heater, a first water pump, and a second water pump. In the second type of control process, when it is necessary to cool the output water temperature, the power between the first water pump and the second water pump can be controlled to adjust the water pressure in the coupling pipe, so that the cold water returning from the return water pipe can enter the outlet water pipe to reduce the output water temperature.

[0034] Preferably, step S2 is as follows: when the electric wall-hung boiler is of type three, the adjustment parameters are the return water temperature and the outlet water temperature, and the control equipment is the heater and the control valve; If the return water temperature is within the temperature range, the heater power is not modified. If the return water temperature is outside the range, it is determined whether the return water temperature is below the temperature range. If the return water temperature is below the temperature range, it is determined whether the outlet water temperature is below the temperature threshold. If the outlet water temperature is below the temperature threshold, the control valve is opened based on the third difference between the temperature threshold and the outlet water temperature. If the outlet water temperature is not below the temperature threshold, the first operation is performed. If the return water temperature is above the temperature range, the first operation is performed.

[0035] Because the third type of electric wall-hung boiler has a control valve that allows hot water from the outlet pipe to enter the cold water pipe for reheating, the adjustment parameters include outlet water temperature, which is an additional parameter compared to the other two types. When the return water temperature is below the temperature range, it is further determined whether the outlet water temperature is below the temperature threshold. If it is, it indicates that the outlet water temperature is insufficient, and the current heater power is insufficient to meet the heating demand. There are two options: first, increase the heater power, which is very energy-intensive; second, reheat the output hot water. To help users save energy, this invention chooses the second approach. This requires opening the control valve to allow some hot water to re-enter the heater for reheating, thus meeting the water temperature output requirements. When the outlet water temperature is not lower than the temperature threshold, but the return water temperature is below the temperature range, the first operation is used to adjust the heater power.

[0036] Preferably, the first operation is: Based on the current return water temperature and the outlet water temperature, the difference between the two is obtained as the first difference. The heater is then adjusted with the first power and run for a preset time. The difference between the return water temperature and the outlet water temperature is obtained again as the second difference value. Based on the second difference and the first difference, obtain the heating parameters; The heating power of the heater is determined by the heating parameters, the current return water temperature, and the temperature range, and then the heating power of the heater is adjusted.

[0037] When performing the first operation, the first power can be either a deceleration power or an increase power operation, depending on whether the return water temperature is above or below the temperature range when performing the first operation. If the return water temperature is below the temperature range, the first power is an increase power; if the return water temperature is above the temperature range, the first power is a decrease power.

[0038] After adjusting the heater to the first power and running it for a preset time, the return water temperature will tend to stabilize. At this point, a second difference can be obtained. The difference between the first and second differences indicates the effect of the first power on the water temperature (heating parameter). Finally, the heater power is adjusted by using the heating parameter, the current return water temperature, and the temperature range to keep the return water temperature within the specified range.

[0039] Specifically, heating parameters , , These are the second and first differences, respectively. t represents the preset time, and the heating parameter K represents the temperature change per unit time (preset time) at the first power level. The required temperature adjustment can be calculated using the current return water temperature and temperature range. This temperature value, along with the heating parameter, allows for the deduction of the required heating power for the corresponding heater.

[0040] Preferably, the power of the first and second water pumps is adjusted based on the return water temperature as follows: The difference between the return water temperature and the upper limit of the temperature range is obtained as the fourth difference, and the target pressure in the coupling pipe is obtained through the fourth difference. Target pressure ,in This is the base pressure value inside the coupling pipe. The coefficient for pressure-temperature conversion was obtained through multiple experiments on the same coupling tube in the laboratory. This is the fourth difference; The pressure integral term is obtained based on the target pressure; Pressure integral term , The previous value of the pressure control integral term. It is the control cycle.

[0041] The power difference between the first and second water pumps is obtained by replacing the trained proportional-integral control integral term with the pressure integral term. The formula for obtaining the power difference is as follows: ,in These are the proportional coefficient and the integral coefficient, respectively. , This is the average of historical pressure error values. Pressure for the target.

[0042] If the power difference is greater than a power threshold, the first water pump is turned on at minimum power and the second water pump is turned on at maximum power. If the power difference is less than the threshold, the power of the first water pump and the second water pump are adjusted based on the power difference so that the power difference between the first water pump and the second water pump meets the power difference.

[0043] First, the fourth difference between the return water temperature and the upper limit of the temperature range is calculated and converted into the target pressure within the coupling pipe, thus deriving the corresponding pressure integral term. This pressure integral term is embedded into a well-trained proportional-integral (PI) control loop, replacing the original integral term, thereby outputting the power difference between the first and second water pumps suitable for the current operating conditions. Subsequently, the system determines whether this power difference exceeds a preset power threshold: if it does, it achieves rapid heat redistribution by setting the first water pump to minimum power and the second water pump to maximum power, maximizing the cooling of the outlet water temperature. If it does not exceed the threshold, it dynamically adjusts the operating power of the two water pumps based on the power difference, ensuring that the power difference precisely matches the calculated target value, thereby gradually and smoothly guiding the return water temperature back to the target range without over-responding. Of course, when adjusting the first and second water pumps, because cold water needs to be introduced into the coupling pipe, the power of the first water pump is reduced or decreased, while the power of the second water pump is increased. When the return water temperature returns to normal, the power of the first and second water pumps returns to the same level, allowing cold water to enter the heater normally for heating.

[0044] A control system for an electric wall-hung boiler with a water distributor, using the control method for the electric wall-hung boiler with a water distributor, includes a type acquisition module, a data acquisition module, and a periodic control module; The type acquisition module is used to confirm the acquired adjustment parameters in response to the type of electric wall-hung boiler; The data acquisition module is used to periodically acquire the adjustment parameters; In response to the judgment of the adjustment parameters, it is determined whether the current electric wall-hung boiler meets the functional requirements. If it does, no adjustment is made to the electric wall-hung boiler. If it does not, the control equipment that needs to be modified is determined based on the type of electric wall-hung boiler and the adjustment parameters. The periodic control module adjusts the control equipment based on the adjustment parameters, repeating step S2 until the electric wall-hung boiler is turned off.
