[0051] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0053] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0054] The electronic control board used in an electric water heater typically includes an interconnected display control board and a power supply board. The display control board interacts with the user, providing an interface that displays the water heater's current status information (such as water temperature and operating mode) and receives user commands via buttons or a touchscreen, such as setting a target temperature or selecting a heating mode. Furthermore, the display control board may have fault diagnosis and alarm functions, promptly notifying the user when the water heater malfunctions. The power supply board supplies power to the entire water heater system and manages electrical energy. In some exemplary embodiments, the power supply board integrates a load drive module and a load sensor module. The load sensor module detects the water temperature in the water heater, and the load drive module heats the water. The display control board receives the water temperature detected by the power supply board, matches the water temperature signal with the heating temperature, and then outputs a control signal to the load drive module of the power supply board to initiate heating.

[0055] However, the display control board in the existing electronic control board includes a display screen and multiple chips. These chips may include a main control chip, a display driver chip, an interaction chip, a wireless communication chip, etc. The presence of multiple chips makes the structure of the display control board more complex. For example, multiple chips will increase the number of chips and components in the display control board, which in turn increases the number of internal wirings in the display control board, ultimately resulting in a complex display control board structure, high manufacturing cost, and low production efficiency.

[0056] Therefore, this utility model provides a display control board, which aims to simplify the internal structure of the display control board without reducing its functionality.

[0057] In one embodiment, such as Figures 1 to 3As shown, the display control board 100 is used for the electronic control component 200. The electronic control component 200 includes a power board 300, which can detect corresponding signals through a sensor module 320. It also includes a circuit board 110, which is equipped with a display module 120 and a first communication component 130. The display module 120 can be used to interact with the user, such as receiving user commands to control the load accordingly, or displaying the load's operating status for the user to understand and perform further operations. The first communication component 130 is electrically connected to the display module 120 and connects the display module 120 to the power board 300 to establish an electrical connection between them. Optionally, the display module 120 can be an LED display, an OLED display, etc., and the first communication component 130 can be a UART serial port, an I2C bus, etc. The specific forms of the display module 120 and the first communication component 130 are not limited here.

[0058] In this embodiment, the display module 120 is equipped with a main control chip 140, which integrates a first control chip 141 and a display driver chip 142. The first control chip 141 is connected to the first communication component 130 and the display driver chip 142, respectively. It can be understood that the first control chip 141 is a control chip for the entire system. For example, it can control the display driver component to drive the display, or it can receive detection signals from the power board 300 and output control signals corresponding to the detection signals to the power board 300, so that the power board 300 performs corresponding driving operations according to the control signals. Therefore, the first control chip 141 is the main control chip 140 for the entire system, and not just a control chip that can only control the display driver chip 142 or control the display module 120 to perform the display.

[0059] In some exemplary display control boards, the display driver chip and the first control chip are connected to the display module respectively. To achieve signal transmission, multiple wirings are often required, leading to complex internal wiring, increased size, high cost, and difficulty in manufacturing. In contrast, this embodiment proposes a main control chip 140 that integrates the first control chip 141 and the display driver chip 142, directly eliminating the wiring required for signal transmission between the first control chip 141 and the display driver chip 142, making it more convenient to use. Thus, by integrating the first control chip 141 and the display driver chip 142 into a single main control chip 140, this invention simplifies the internal structure of the display control board 100. This not only reduces the number of required wirings and lowers circuit complexity but also reduces the overall size of the display control board 100, thereby improving production efficiency and helping to reduce manufacturing costs.

[0060] It is understandable that the existing technology requires the display module to be designed as a double-sided panel in order to achieve the connection between the display module and each chip. However, in this embodiment, by setting the main control chip 140 in the display module 120, the display module 120 can adopt a single-sided panel design. This saves certain costs, simplifies the layout of circuits and wiring, and reduces the setting of peripheral circuits for individual chips.

[0061] It should be explained that the main control chip 140 can be used to receive the first signal fed back by the power board 300 through the first communication component 130, and to output corresponding load control signals and display control signals according to the first signal; wherein, the display control board 100 is connected to the power board 300 through the first communication component 130. Optionally, the first signal fed back by the power board 300 is transmitted to the main control chip 140, and the first control chip 141 in the main control chip 140 processes the first signal. This processing may include, but is not limited to, steps such as digital-to-analog conversion, signal parsing, and logic judgment, in order to convert the first signal fed back by the power board 300 into a matching or corresponding load control signal and display control signal.

[0062] Furthermore, the load control signal is transmitted back to the power supply board 300 and received by the load driver chip of the power supply board 300. The load driver chip drives the load to perform corresponding operations according to the load control signal. For example, when the load is an electric water heater, the load control signal can be used to control the electric water heater to produce hot water. It can be understood that the first communication component 130 can not only transmit signals from the power supply board 300 to the display control board 100, but also transmit signals from the display control board 100 to the power supply board 300, enabling bidirectional communication.

[0063] In addition, the first control chip 141 generates a display driving signal based on the first signal fed back by the power board 300, which can be transmitted to the display driver chip 142. The display driver chip 142 can control the display module 120 to display the corresponding content according to the display driving signal.

[0064] In an example application scenario, such as during the control of an electric water heater, when a user sets a target water temperature (e.g., 50°C) and starts heating via the display control board 100, the sensor module 320 within the power board 300 monitors the current actual water temperature (e.g., 30°C) and sends this temperature data as a first signal to the display control board 100 via the first communication component 130. Upon receiving this simulated signal from the power board 300, the main control chip 140 first performs analog-to-digital conversion, converting it into a digital signal, and then analyzes this signal to determine the current water temperature. Based on the user-set target temperature and the actual water temperature, the main control chip 140 performs logical judgment and generates two signals: one is a load control signal, sent back to the power board 300 via the first communication component 130, instructing the load drive module 330 of the power board 300 to start the heating element and heat the water to the target temperature; the other is a display control signal, transmitted to the display driver chip 142 integrated within the main control chip 140, updating the content of the display module 120 to display the current water temperature and the target temperature. Throughout the heating process, the power board 300 can continuously monitor water temperature changes and periodically send the latest water temperature data to the display control board 100 via the first communication component 130, so that the display control board 100 can update the display screen content in real time and ensure that the user can see the latest status information.

[0065] In summary, this utility model proposes a display control board 100, aiming to simplify its internal structure, improve production efficiency, and reduce manufacturing costs through integrated design. The display control board 100 includes a circuit board 110, on which a display module 120 and a first communication component 130 are disposed. The display module 120 contains a multi-integrated main control chip 140, which integrates a first control chip 141 and a display driver chip 142, thereby reducing the number of independent chips. The first control chip 141 is not only connected to the first communication component 130 but also directly connected to the display driver chip 142, achieving centralized control of the entire system. The main control chip 140 receives a first signal (such as water temperature data) fed back from the power board 300 through the first communication component 130, processes it, and generates corresponding load control signals and display control signals. The load control signal is transmitted back to the power board 300 via the first communication component 130 to control the operation of the heating element; while the display control signal is received by the display driver chip 142 and can be used to update information on the display module 120, such as the current water temperature and operating status. Thus, this display control board 100 simplifies its internal wiring and reduces its size without reducing its functionality, thereby simplifying its internal structure.

[0066] In one embodiment, such as Figure 1 As shown, the display control board 100 also includes an interaction component 150, and the main control chip 140 integrates an interaction processing module 143. The interaction processing module 143 is connected to the interaction component 150 and the first control chip 141, respectively. Compared to some exemplary display control boards that separately set up a first control chip, a display driver chip, and an interaction processing module, requiring multiple chips and resulting in a complex internal structure, the main control chip 140 of the display control board 100 in this embodiment not only integrates the first control chip 141 and the display driver chip 142, but also further integrates the interaction processing module 143. Without increasing the number of independent chips, the functionality of the main control chip 140 is increased. Therefore, compared to exemplary technologies, this main control chip 140 simplifies the wiring on the circuit board 110, thereby reducing manufacturing costs and improving production efficiency, thus simplifying the display control board 100.

[0067] Understandably, the interaction component 150 further enhances the user's interaction capabilities with the system. The interaction processing module 143 is connected to the interaction component 150 and the first control chip 141, forming a signal processing link. Optionally, the interaction component 150 can be a touchscreen, a button, or other user input device. It can also be a voice recognition device, a gesture recognition device, etc., all used to receive user operation commands and trigger a second signal. In one example, when the user operates through the interaction component 150 (e.g., setting a target temperature or selecting a heating mode), the interaction component 150 generates a corresponding second signal, which is then transmitted to the interaction processing module 143 integrated in the main control chip 140.

[0068] In addition, after receiving the second signal, the interaction processing module 143 parses and processes it, converting it into an interaction signal suitable for system use. The conversion process may include signal formatting, verification, and preliminary processing to ensure the accuracy and validity of the signal. The processed interaction signal is then sent to the first control chip 141, which processes the interaction signal to output corresponding load control signals and display control signals.

[0069] like Figures 1 to 3As shown, the signal flow of the load control signal and display control signal for the second signal is the same as that of the load control signal and display control signal for the first signal. An exemplary application scenario is given, for example, during the use of an electric water heater, the first communication component 130 is connected to the power board 300. When the user sets the target water temperature (e.g., 50°C) and selects the heating mode through the interaction component 150 (e.g., a touchscreen or buttons), the interaction component 150 generates a corresponding second signal. The second signal is then transmitted to the interaction processing module 143 integrated in the main control chip 140. The interaction processing module 143 parses and performs preliminary processing on the received second signal to ensure its accuracy and validity, and outputs the corresponding interaction signal. The interaction signal is then sent to the first control chip 141 in the main control chip 140. After receiving the interaction signal, the first control chip 141 performs logical judgment based on the user-set target temperature and the actual water temperature data obtained from the power supply board 300, and generates two signals: one is a load control signal, which is sent back to the power supply board 300 through the first communication component 130, instructing the load drive module 330 of the power supply board 300 to start the heating element and heat the water to the target temperature; the other is a display control signal, which is transmitted to the display driver chip 142 integrated in the main control chip 140 to update the content of the display module 120 and display the current water temperature and the target temperature. Throughout the heating process, the power supply board 300 continuously monitors water temperature changes and periodically sends the latest water temperature data to the display control board 100 through the first communication component 130, so that the display control board 100 can update the display screen content in real time and ensure that the user can see the latest status information. In addition, if the user wants to change the working mode or adjust the target temperature, they only need to input a new command again through the interaction component 150, and the whole process will repeat the above steps, thereby realizing flexible control of the electric water heater.

[0070] Optionally, the interactive component 150 includes a touch button, and the interactive processing module 143 includes a touch button processing module. Using a touch button as the interactive component 150 can provide a more intuitive and convenient operating experience. At the same time, the presence of the touch button processing module makes the entire system respond to user input more quickly and accurately.

[0071] In one embodiment, the display module 120 includes a first housing and a digital tube 121 disposed in the first housing. The main control chip 140 is disposed in the first housing, and the display driver chip 142 is connected to the digital tube 121. The display driver chip 142 can be used to drive the digital tube 121 to perform corresponding operations so that the display module 120 displays corresponding information.

[0072] In this embodiment, the first housing refers to the external protective structure or shell of the display module 120, which can be used to house and protect various internal electronic components, such as the main control chip 140 and the digital tube 121. The first housing not only provides physical protection but can also be designed in different shapes and sizes to suit the appearance requirements of different products. The digital tube 121 is housed within the first housing. The digital tube 121 can consist of multiple LEDs, each representing a segment. By lighting different combinations, it displays the numbers 0-9 and some simple characters. The digital tube 121 is low-cost, highly reliable, and easy to read. Furthermore, the main control chip 140 is also placed within the first housing, meaning the core of the entire control system is compactly integrated, which helps improve the system's stability and reliability. In addition, this layout facilitates production and maintenance.

[0073] Furthermore, the display driver chip 142 is specifically responsible for driving the digital tube 121. It receives instructions from the main control chip 140 and controls the on / off state of each LED segment in the digital tube 121 accordingly, thereby displaying specific information. This separate design allows each component to focus on its own task, improving the overall efficiency of the system.

[0074] In one embodiment, such as Figure 1 As shown, the main control chip 140 also integrates a WIFI module 144, which is connected to the first control chip 141. Thus, the display control board 100 has wireless communication capabilities, enabling remote control, data transmission and other functions.

[0075] Understandably, the WIFI module 144 allows the display control board 100 to connect to the internet or other devices via a wireless network, such as a user's smartphone or other smart devices in the home network. The WIFI module 144 is directly connected to the first control chip 141 within the main control chip 140, meaning the first control chip 141 can directly manage and control all operations of the WIFI module 144, including establishing network connections and sending / receiving data. Thus, users can remotely view the status of the electric water heater (such as current water temperature, operating mode, etc.) and make corresponding settings adjustments (such as setting a target temperature, turning heating on / off, etc.) through a mobile application or other networked devices.

[0076] Furthermore, the WIFI module 144 can be used to receive a third signal and output a wireless control signal corresponding to the third signal; the first control chip 141 can also be used to output corresponding load control signals and display control signals according to the wireless control signal. The third signal refers to data or instructions received through a wireless network, such as control commands sent by a user through a smartphone application (e.g., setting a target temperature, starting / stopping heating, etc.). After the WIFI module 144 performs preliminary processing on the received third signal, it generates a corresponding wireless control signal, which contains key information from the original data and is formatted in a form that the first control chip 141 can recognize and process.

[0077] It is understandable that the signal flow of the load control signal and display control signal for the third signal is the same as that of the load control signal and display control signal for the first signal and the second signal, and will not be described again here.

[0078] In one embodiment, the display control panel 100 further includes an alarm component connected to the first communication component 130, which can be used to trigger an alarm when the first communication component 130 outputs a control signal. It is understood that the alarm component 160 can be an audible alarm, a visual alarm, or a combination of both; in this embodiment, the alarm component 160 is a buzzer.

[0079] In conjunction with all the embodiments described above, the display control board 100 significantly simplifies its internal structure by integrating the first control chip 141, the display driver chip 142, the interactive processing module 143, and the WIFI module 144 onto a single main control chip 140. This highly integrated design reduces the number of discrete components and complex internal wiring on the circuit board 110, thereby lowering manufacturing costs and improving production efficiency and system reliability. By reducing connection points and optimizing signal processing paths, this solution enhances system response speed and stability while supporting remote control and intelligent alarm functions, thus providing a more compact, efficient, and easy-to-maintain solution without sacrificing functionality.

[0080] like Figure 2 As shown, this utility model also provides an electronic control component 200, which includes a display control board 100 and a power supply board 300. It should be noted that the electronic control component 200 includes a power supply board 300 and a display control board 100. The specific structure of the display control board 100 is as described in the above embodiments. Since this electronic control component 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0081] In this embodiment, the power board 300 is provided with a second communication component 310, and the first communication component 130 of the display control board 100 is interconnected with the second communication interface of the power board 300. The second communication component 310 can be used to connect to the display control board 100, transmitting data collected by the power board 300 (e.g., water temperature, operating status, etc.) to the display control board 100, and also receiving control signals from the display control board 100 to perform corresponding operations (e.g., starting heating, adjusting temperature, etc.).

[0082] It should be noted that since the electronic control component 200 uses the display control board 100 in the above embodiment, and since the display control board 100 has a simple internal structure, the electronic control component 200 also has a simple internal structure, which helps to reduce manufacturing costs and facilitates production.

[0083] In one embodiment, the power board 300 includes a power module 350 and a second control chip 340, a sensor module 320, and a load drive module 330, which are respectively connected to the power module 350; the sensor module 320, the load drive module 330, and the second communication component 310 are respectively connected to the second control chip 340, and the sensor module 320 and the load drive module 330 are respectively connected to the load.

[0084] In this embodiment, the power module 350 is the foundation of the entire power board 300 and can be used to provide the power required by all other components, so that each module or chip can work effectively.

[0085] In this embodiment, the second control chip 340 is the core controller of the power board 300, responsible for coordinating the operation of various components. The second control chip 340 is connected to the power module 350, sensor module 320, load drive module 330, and second communication component 310. The main functions of the second control chip 340 include receiving data from the sensor module 320, processing this data, and sending the results to the first control chip 141 of the display control board 100 through the second communication component 310. In addition, the second control chip 340 also controls the operation of the load drive module 330 according to the control signals received from the first control chip 141.

[0086] In this embodiment, the sensor module 320 can be used to detect the operating parameters of the load (such as an electric water heater) in real time, such as water temperature and current. The sensor module 320 transmits the collected data to the second control chip 340, which processes the raw data, generates corresponding parameter signals, and sends them to the first control chip 141 of the display control board 100 through the second communication component 310.

[0087] In this embodiment, the load drive module 330 can be used to control the actual working state of the load according to the instructions of the second control chip 340, such as starting or stopping the heating element, to ensure that the electric water heater can operate according to the target temperature set by the user.

[0088] In some exemplary power boards, there is no control module, only a separate load drive module and sensor module. Therefore, a lot of wiring is required for the load drive module and sensor module to achieve the corresponding signal transmission. For example, when it is necessary to establish a connection with the chip and module of the display control board, multiple channels are required to connect the load drive module and sensor module to the display control board respectively. Such a layout not only increases the complexity of the circuit, but also results in an excessively long signal transmission path, thereby affecting the system's response speed and reliability. Therefore, in this embodiment, a second control chip 340 is added to the power board 300. The load drive module 330 and the sensor module 320 receive and send signals through the second control chip 340. In this way, the signal transmission of the load drive module 330 and the sensor module 320 is uniformly managed by the second control chip 340. That is, the load drive module 330 and the sensor module 320 no longer communicate directly with the display control board 100 or other external devices, but the signals are centrally processed and forwarded through the second control chip 340. This reduces the number of wires inside the power board 300. The second control chip 340 only needs to be connected to the display control board 100 through the second communication interface, which simplifies the circuit design, reduces manufacturing costs, and improves production efficiency.

[0089] It is understood that the second control chip 340 is used to receive the detection signal output by the sensor module 320 and output the detection signal to the first control chip 141 of the display control board 100 through the second communication component 310; it is also used to receive and output a corresponding control signal to the second control chip 340 according to the detection signal; and it is also used to output a corresponding display control signal to the display driver component according to the detection signal to drive the display module 120 to perform a corresponding display; the second control chip 340 is also used to control the load driver module 330 to drive the load according to the control signal.

[0090] In one embodiment, the load includes a hot water device, the sensor module 320 of the power board 300 is specifically a temperature sensor, and the load drive module 330 of the power board 300 is specifically a heating drive module.

[0091] In an exemplary application scenario, a temperature sensor monitors the operating parameters (such as water temperature) of an electric water heater in real time and sends this data to a second control chip 340. The second control chip 340 performs preliminary processing on the received raw data, such as filtering and calibration, and then converts the processed data into a standard parameter signal, which is sent to the first control chip 141 of the display control board 100 via a second communication component 310 (such as a UART serial port or I2C bus). Upon receiving the parameter signal, the first control chip 141 further processes it, such as parsing and logical judgment, generating a corresponding control signal and sending it back to the second control chip 340 of the power board 300 via a first communication component 130. Simultaneously, the first control chip 141 also generates a display control signal to update information on the display module 120, such as the current water temperature and the target temperature. When the second control chip 340 receives a control signal from the display control board 100, it controls the heating drive module to perform corresponding operations, such as starting or stopping the heating element, based on the control signal.

[0092] This utility model also provides a power board 300, such as Figure 3 As shown, the power board 300 is used in the electronic control component 200 as described above. The power board 300 includes a second control chip 340, a sensor module 320, a load drive module 330, and a second communication component 310. The sensor module 320, the load drive module 330, and the second communication component 310 are respectively connected to the second control chip 340. The sensor module 320 and the load drive module 330 are respectively connected to the load. The second communication component 310 is connected to the display control board 100. The second control chip 340 is used to receive the detection signal output by the sensor module 320 and output the detection signal to the display control board 100 through the second communication component 310. The display control board 100 is used to receive and output a corresponding control signal to the second control chip 340 according to the detection signal. The second control chip 340 is also used to control the load drive module 330 to drive the load according to the control signal.

[0093] It is understood that in this embodiment, the second control chip 340 is connected to the display control board 100. However, in some other application scenarios, other types of control boards may be used, such as independent microcontroller units (MCUs) or dedicated control modules. Regardless of the type of control board, its core function is to process the received parameter signals and generate corresponding control signals to effectively manage the power board 300. The benefit is reduced wiring and simplified structure.

[0094] Understandably, some exemplary power boards do not have a control module, but only separate load drive modules and sensor modules. Therefore, a lot of wiring is required for these load drive modules and sensor modules to achieve the corresponding signal transmission. For example, when it is necessary to establish a connection with the chip and module of the display control board, multiple channels are required to connect the load drive module and sensor module to the display control board respectively. Such a layout not only increases the complexity of the circuit, but also results in excessively long signal transmission paths, thereby affecting the system's response speed and reliability. Therefore, in this embodiment, a second control chip 340 is added to the power board 300. The load drive module 330 and the sensor module 320 receive and send signals through the second control chip 340. In this way, the signal transmission of the load drive module 330 and the sensor module 320 is uniformly managed by the second control chip 340. That is, the load drive module 330 and the sensor module 320 no longer communicate directly with the display control board 100 or other external devices, but the signals are centrally processed and forwarded through the second control chip 340. This reduces the number of wires inside the power board 300. The second control chip 340 only needs to be connected to the display control board 100 through the second communication interface, which simplifies the circuit design, reduces manufacturing costs, and improves production efficiency.

[0095] In one embodiment, the load includes a hot water device, the sensor module 320 is specifically a temperature sensor, and the load drive module 330 is specifically a heating drive module. It can be understood that the temperature sensor is used to detect the water source temperature of the hot water device, and the heating drive module is used to drive the heating component to perform heating work.

[0096] This utility model also provides a hot water device, which includes a display control board 100; or an electrical control component 200; or a power supply board 300. It should be noted that the specific structures of the display control board 100, the electrical control component 200, and the power supply board 300 are as described in the above embodiments. Since this hot water device adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be elaborated further here.

[0097] In this embodiment, the hot water device can be one of an electric water heater, a gas water heater, a gas wall-hung boiler, a hot water boiler, or a hot water furnace. The specific device is not limited here. Importantly, by using the display control board 100, power board 300, or electronic control component 200 described in the previous embodiment, the hot water device can achieve the beneficial effect of simplifying the internal structure.

[0098] In one embodiment, the hot water device further includes a housing located at the target position and a device body disposed within the housing. The hot water device also includes the electronic control component 200, which is disposed within the device body. The electronic control component 200 includes a display control board 100 and a power board 300. The display control board 100 has a first communication component 130, and the power board 300 has a second communication component 310. After the display control board 100 and the power board 300 are installed in the device body, the interfaces of the first communication component 130 and the second communication component 310 face downwards. It is understood that when the display control board 100 and the power board 300 are installed inside the device body, the interfaces of the first communication component 130 and the second communication component 310 face downwards. This reduces the risk of dust and water droplets entering the interfaces and improves the service life of the device.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
