By turning on the fan and heating the heating element, the air generated by the fan is heated after passing through the heating element. However, currently, when smart toilets perform the drying function, the air temperature cannot change steadily, causing users to be exposed to hot or cold air for short periods, thus reducing the drying experience of the smart toilet. Summary of the Invention

[0004] The main objective of this application is to provide a control method, control device, and smart toilet for a smart toilet, which can smoothly control the changes in air temperature and improve the drying experience of the smart toilet.

[0005] To achieve the above objectives, a first aspect of this application provides a control method for a smart toilet.

[0007] In some embodiments, the power increment is obtained through the following steps: when the fan is operating at the target speed, the heating power of the heating device is adjusted, and after each adjustment of the heating power, the temperature value of the wind generated after the fan rotates on the heating device is obtained; when the temperature value reaches the target temperature and continues to exceed a first preset time threshold, the currently adjusted heating power is determined as the target power; a first target time for the fan speed to increase from the initial speed to the target speed is obtained, and the target power is calculated based on the first target time to obtain the power increment.

[0008] In some embodiments, the initial heating power is obtained through the following steps: when the fan is operating at the target speed, the heating power of the heating device is adjusted, and after each adjustment of the heating power, the temperature value of the wind generated after the fan rotates on the heating device is obtained; when the temperature value is lower than the target temperature and continues to exceed a second preset time threshold, the currently adjusted heating power is determined to be the initial heating power.

[0009] In some embodiments, the control method further includes: in response to a stop heating command from the smart toilet, turning off the heating device; and simultaneously turning off the heating device, controlling the fan speed to gradually decrease from the target speed to zero.

[0010] In some embodiments, controlling the fan speed to gradually decrease from the target speed to zero includes: obtaining a second target time for the fan speed to decrease from the target speed to zero; performing a differential integral on the target speed based on the second target time to obtain the speed reduction; and controlling the fan speed to decrease from the target speed to zero according to the speed reduction, wherein the speed reduction is the difference between any two adjacent speeds during the fan speed adjustment process.

[0011] In some embodiments, the control method further includes: in response to a cold air command from the smart toilet, turning on the fan and recording the drying time; and turning off the fan when the drying time reaches a preset duration.

[0012] To achieve the above objectives, a second aspect of this application provides a smart toilet, comprising: a start-up module, configured to, in response to a heating command from the smart toilet, turn on the fan on the smart toilet at a preset initial speed and control the speed of the fan to gradually increase from the initial speed; an adjustment module, configured to, while turning on the fan, simultaneously start the heating device on the smart toilet at a preset initial heating power to increase the temperature of the air generated after the fan rotates and passes through the heating device, and control the heating power of the heating device to gradually increase from the initial heating power as the speed of the fan gradually increases; and a constant temperature module, configured to, when the speed of the fan increases to a preset target speed, obtain the target power to which the heating power increases as the air temperature gradually heats to the target temperature, control the fan to rotate at a uniform speed at the target speed, and control the heating device to heat at the target power.

The memory stores a computer program, and the processor executes the computer program to implement the method described in the first aspect of the present application.

[0014] To achieve the above objectives, a fourth aspect of this application provides an intelligent toilet, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the method described in the first aspect of the embodiment.

[0015] This application discloses a control method, control device, and smart toilet for a smart toilet, which has the following beneficial effects: In response to a heating command from the smart toilet, the fan on the smart toilet is turned on at a preset initial speed, and the fan speed is gradually increased from the initial speed. Simultaneously with turning on the fan, the heating device on the smart toilet is activated at a preset initial heating power, ensuring that the air temperature after passing through the heating device is not excessively high during the heating activation phase. Furthermore, as the fan speed is gradually increased, the heating power of the heating device is gradually increased from the initial heating power, with each small increase ensuring proper heating. The power increases gradually, and the wind speed also increases gradually, so that the air temperature generated by the fan gradually rises to the target temperature after passing through the heating device. This achieves a more gradual temperature increase rather than a sudden increase. Furthermore, when the fan speed increases to the preset target speed, the target power increase in heating power is obtained as the air temperature gradually heats up to the target temperature. The fan is controlled to rotate at a constant speed at the target speed, and the heating device is controlled to heat at the target power to maintain the air temperature at the target temperature. During the process of heating the air temperature to the target temperature, the temperature change can be smoothly controlled by gradually increasing the heating power while increasing the fan speed, thus improving the drying experience of the smart toilet.

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0032] A smart toilet is a bathroom product that integrates high-tech functions. It uses various advanced technologies and sensors to provide a more convenient, comfortable, and hygienic user experience. A smart toilet can provide a drying function after use to help the user's bottom dry quickly, replacing traditional paper towels or hand towels.

[0033] In related technologies, the drying function of smart toilets is achieved through a fan and a heating element. By turning on the fan and heating the heating element, the air generated by the fan is heated after passing through the heating element. However, currently, when smart toilets perform the drying function, the air temperature cannot change steadily, causing users to be exposed to hot or cold air for short periods, thus reducing the drying experience of the smart toilet.

[0034] Based on this, embodiments of this application provide a control method, control device, and smart toilet for a smart toilet, which can smoothly control changes in air temperature and improve the drying experience of the smart toilet.

[0035] This application provides a control method, control device, and smart toilet for a smart toilet, which will be described in detail through the following embodiments. First, the control method of the smart toilet in this application embodiment is described.

[0036] The control method for the smart toilet in this application can be illustrated through the following embodiments.

[0037] Figure 1 This is an optional flowchart of the control method for a smart toilet provided in the embodiments of this application. Figure 1 The method may include, but is not limited to, steps S101 to S103.

[0038] Step S101: In response to the heating command of the smart toilet, turn on the fan on the smart toilet at the preset initial speed and control the speed of the fan to gradually increase from the initial speed.

[0039] The subject of this application is a smart toilet, specifically executed by the processor (Central Processing Unit, CPU) within the smart toilet. In the smart toilet, the processor is responsible for controlling various functions and performing various operations, such as detecting sensor data, controlling flushing, and adjusting temperature. The processor executes pre-set programs and algorithms, making decisions and operations based on input signals and internal states to realize the various functions of the smart toilet.

[0040] Understandably, the heating command on a smart toilet refers to the process of blowing warm air towards the buttocks area after the user has finished defecating or urinating, achieving a drying effect and providing a more convenient, hygienic, and comfortable user experience. Heating commands for smart toilets can be sent via heating buttons or symbols on the control panel; users can turn the heating function on or off by pressing the button or selecting the corresponding symbol. When the heating function is on, the smart toilet uses its heating element to blow heated air through the fan. Heating commands can also be sent using the corresponding buttons on the remote control that comes with the smart toilet. Alternatively, heating can be controlled via a companion smartphone app.

[0041] It's understandable that the preset initial speed refers to the rotational speed of the fan on the smart toilet when the drying function is activated in response to a heating command. In the use of a smart toilet, the preset initial speed is set according to user needs and design specifications. It is adjusted to meet the user's requirements for comfort and drying effect. Activating the fan on the smart toilet at the preset initial speed ensures that the drying effect is not too poor due to insufficient airflow, nor is the user uncomfortable due to excessive initial airflow, providing a fast, effective, and comfortable drying experience.

[0042] Understandably, controlling the fan speed by gradually increasing it from an initial speed can be achieved through software algorithms. This can be done by integrating the developed software algorithm into the smart toilet's control system—that is, by interfacing the smart toilet's hardware and software—to ensure the algorithm can control the fan speed. Incremental functions or other algorithms can be used to control the rate and time interval of the fan speed increase.

[0043] Step S102: While turning on the fan, the heating device on the smart toilet is heated at a preset initial heating power to increase the temperature of the air generated by the fan after it passes through the heating device. As the fan speed is gradually increased, the heating power of the heating device is controlled to gradually increase from the initial heating power.

[0044] It is understandable that the preset initial heating power refers to the heating power of the heating device when responding to the heating command and activating the heating function of the smart toilet. The preset initial heating power is set after considering user needs and energy efficiency, so that the air temperature can quickly reach a comfortable temperature, preventing the heating device from overheating and avoiding excessively high air temperature during the drying stage, thus providing a comfortable experience for the user.

[0045] Understandably, the heating element generates warm air, which is then blown to the user's buttocks area by a fan to achieve a drying effect. The heating element is built into the toilet's structure and can consist of an electric heating element, such as a heating wire, heating coil, or heater. The heating element is connected to the smart toilet's control system, which adjusts parameters such as heating power. Users can also control these parameters via buttons on the control panel, a remote control, or other control devices to meet their individual needs and preferences.

[0046] It's understandable that air temperature refers to the temperature reached by the air generated after the fan rotates and passes through the heating device. Temperature sensors or other air temperature monitoring devices can be used on smart toilets to monitor changes in air temperature in real time. Gradually increasing the fan speed can be achieved by controlling the fan's current or voltage. An increment function or other control algorithm can be used to adjust the rate and interval of the fan speed increase. Controlling the heating power of the heating device to gradually increase from an initial heating power can also be done using an increment function or other control algorithm to adjust the rate and interval of power increase. As the fan speed gradually increases, the hot air is transferred more quickly, and the gradually increasing heating power provides more heat. The air temperature gradually rises after passing through the heating device, preventing the air from becoming overheated or underheated in a short period, achieving a smooth temperature change process, and providing a more comfortable drying experience that meets user needs.

[0047] Step S103: When the fan speed increases to the preset target speed, the target power to which the heating power increases as the air temperature gradually heats to the target temperature is obtained, the fan is controlled to rotate at a uniform speed at the target speed, and the heating device is controlled to heat at the target power.

[0048] Understandably, the target speed is the set desired fan speed, causing the fan to operate at a specific speed to provide appropriate airflow and drying effect. Smart toilets offer multiple fan speed options, such as low, medium, and high, allowing users to select the appropriate target speed according to their needs. Smart toilets can also offer preset drying modes, each with a specific target speed and drying time. The fan is connected to the control system, monitoring its speed and providing feedback signals to the control system, which can then determine whether the fan has reached the target speed.

[0049] Understandably, the target temperature refers to the desired temperature value set during the drying process, providing a comfortable drying experience for the user. It is set according to specific needs, design requirements, or user preferences. It is adjusted and configured through system control parameter settings, temperature adjustment devices, or the control panel. Smart toilets' drying functions offer multiple temperature options to meet the needs of different users. Target temperatures can be between 30 and 40 degrees Celsius, suitable for users who are temperature-sensitive or interested in a lower level of warmth; between 40 and 50 degrees Celsius, suitable for most users, providing moderate warmth and comfort; and between 50 and 60 degrees Celsius, suitable for users who desire higher temperatures and a more intense drying effect.

[0050] Understandably, the target power is the power level at which the heating device increases its power as the fan speed reaches the target speed and the air temperature gradually heats up to the target temperature. By setting an appropriate target power for the heating device after reaching the desired target speed, it is possible to ensure that the air inside the toilet receives a sufficient and just-right amount of energy. Setting the target power also ensures that the air temperature remains stable, achieving accurate control over both the air temperature and the fan speed.

[0051] Understandably, controlling the fan to rotate at a constant speed at the target rotation speed can be achieved by using a suitable controller (such as a PID controller) to monitor and control the fan's rotation speed. The controller can adjust the fan's output power based on the difference between the actual and target rotation speeds to stabilize the speed near the target. Similarly, controlling the heating device to heat at the target power can also be achieved using a controller to monitor and control the heating power. The controller can adjust the heating device's output based on the difference between the actual and target power to stabilize the heating power at the target. Controlling the fan to rotate at the target speed and controlling the heating device to heat at the target power provides a stable output of heat. Combined with a constant fan speed, this allows the smart toilet to deliver a stable air temperature, providing a comfortable and consistent drying experience for the user.

[0052] In response to a heating command from a smart toilet, this embodiment activates the fan on the smart toilet at a preset initial speed. The fan speed is then gradually increased from the initial speed. Simultaneously with activating the fan, the heating device on the smart toilet begins heating at a preset initial heating power. This ensures that the air temperature after passing through the heating device is not excessively high during the initial heating phase. As the fan speed gradually increases, the heating power of the heating device is also gradually increased from the initial power. Each small increase in power results in a slow and gradual rise in the heating power, causing the air temperature to gradually rise to the target temperature. This achieves a more gradual temperature increase rather than a sudden increase. Once the fan speed reaches the preset target speed, the target power level is obtained, allowing the fan to rotate at a constant speed at the target speed and the heating device to maintain the air temperature at the target power. By gradually increasing the fan speed and heating power simultaneously during the process of heating to the target temperature, the air temperature can be smoothly controlled, improving the drying experience of the smart toilet.

[0053] Please see Figure 2 In some embodiments, step S102 may include steps S201 to S202:

[0054] Step S201: Obtain a preset power increment, wherein the power increment is the difference between any two adjacent heating powers during the heating power adjustment process, and the power increment is determined based on the target power;

[0055] It is understandable that power increment refers to the change in heating power over a certain period of time, used to describe the degree of power change between two adjacent time points in a heating system. The power increment is calculated by comparing the heating power values at two time points and then calculating the difference between them. Assume there are two time points t1 and t2, with corresponding heating power values P1 and P2, respectively. The power increment ΔP can be calculated using the following formula: ΔP = P2 - P1, where ΔP represents the power increment, P2 represents the heating power at the later time point, and P1 represents the heating power at the earlier time point. When the two time points t1 and t2 approach infinity, the increase in power value can be controlled to be more stable. Assuming p(t1) is the heating power value at time t1, then p(t1 + Δt) is the heating power value at time t1 after adding a small time interval Δt. lim represents the operation of taking the limit, and the power increment ΔP is:

[0056] △P=lim △t [p(t1+△t)-p(t1)]

[0057] Understandably, the sign of the power increment indicates the direction of power change. A positive value for ΔP indicates an increase in heating power; a negative value for ΔP indicates a decrease in heating power. The power increment plays a crucial role in control systems, used to monitor and regulate power changes during the heating process. By controlling the magnitude and rate of change of the power increment, the stability and responsiveness of the heating system can be controlled.

[0058] Understandably, the target power is the increase in heating power of the heating device after the fan reaches its target speed and the air temperature gradually reaches the target temperature. Once the fan speed reaches the desired target speed, the air speed stabilizes. By setting the target power of the heating device, it's ensured that the air inside the toilet receives sufficient and appropriate energy, allowing the smart toilet to blow air at a stable temperature and speed. Setting the target power ensures that the air temperature remains stable, achieving accurate control of air temperature and speed. The power increment is determined based on the target power. In actual smart toilet drying applications, determining the power increment based on the target power allows for better control of the heating process, ensuring that the heating power is adjusted around the target power, avoiding excessive power fluctuations, maintaining the stability of the heating process, and meeting the requirement for a smooth rise in air temperature.

[0059] Step S202: The heating power of the heating device is gradually increased from the initial heating power according to the power increment control.

[0060] Understandably, the initial heating power is the starting point of the heating process, allowing the air temperature to quickly reach a comfortable level. This prevents the heating device from overheating and avoids excessively high air temperatures during the drying process, providing a comfortable user experience. Based on system requirements and control strategies, the magnitude of each power increment is determined. This can be a fixed increment or an adaptive adjustment based on actual conditions. Starting from the initial heating power, adjustments are made gradually based on the power increment. After each adjustment, the heating power increases accordingly. For example, if the initial power is P... t0 The power increment is ΔP t Then the next power value can be calculated as P. t1 =P t0 +ΔP t Next, use P t1 As the new initial power, it is adjusted again according to the power increment to obtain P. t2 =P t1 +ΔP t Similarly, as the fan speed increases to the target speed, the heating power is gradually increased according to the set steps to gradually provide more heat, so that the air temperature rises steadily.

[0061] Understandably, as the fan speed increases to the target speed, the heating power of the heating device is gradually increased from the initial power based on the power increment. This gradual increase in heat supply ensures a smooth rise in the air temperature of the smart toilet dryer, avoiding sudden temperature changes and preventing uncomfortable heat sensations during the drying process. It also prevents overheating and reduces the risk of burns. A sudden increase in air temperature or reaching excessively high temperatures could cause burns to the user's skin. By gradually increasing the heating power, the air temperature rises smoothly, keeping it within a safe range and protecting the user's skin. Simultaneously, a stable temperature rise provides a gentler and more comfortable drying effect.

[0062] Please see Figure 3 In some embodiments, the power increment is obtained through steps S301 to S303:

[0063] Step S301: When the fan is working at the target speed, adjust the heating power of the heating device, and after each adjustment of the heating power, obtain the temperature value of the air generated after the fan rotates on the heating device.

[0064] Understandably, when the fan operates at the target speed, ensuring the measured air temperature is at that speed is crucial. To determine the appropriate target power, the heating power of the heating device is adjusted and tested multiple times. After each adjustment, the temperature of the air generated by the fan passing through the heating device is recorded, resulting in multiple sets of different temperature values at the target speed under different heating powers. These multiple sets of heating power and corresponding temperature data help determine the target power in a stable state, ensuring a stable temperature output at the fan's target speed and maintaining the air temperature at the target output temperature. By comparing and analyzing multiple temperature values, temperature changes under different heating powers can be observed and evaluated. When the temperature reaches the target temperature and continues to exceed a set time threshold, the currently adjusted heating power can be determined as the target power.

[0065] Step S302: When the temperature value reaches the target temperature and continues to exceed the first preset time threshold, the currently adjusted heating power is determined to be the target power.

[0066] Understandably, the first preset time threshold refers to observing whether the temperature value can be maintained for a preset period of time after adjusting the heating power. This can be used to verify the continuity of the air temperature and serve as a basis for decision-making, determining whether the heating power is suitable as the target power. Appropriate heating power can provide stable heat to the air inside the toilet, maintaining a stable air temperature from the smart toilet when the fan speed reaches the target speed. For example, the first preset time threshold can be set to 5 minutes. After adjusting the heating power, observe whether the air temperature reaches the target temperature and remains there for more than 5 minutes. If the temperature reaches the target temperature and remains there for more than 5 minutes, the currently adjusted heating power can be determined as the target power.

[0067] Understandably, determining the currently adjusted heating power as the target power by measuring the temperature reaching the target temperature and the first preset time threshold ensures that the air temperature of the drying function is effective and can remain stable for a period of time. By setting the first preset time threshold, it is possible to avoid misjudging whether the temperature has reached the target temperature due to instantaneous temperature fluctuations or noise. Ensuring that the temperature continuously exceeds the first preset time threshold eliminates interference from temporary factors, ensuring the stability and reliability of the heating process, and determining the most suitable target power.

[0068] Step S303: Obtain the first target time for the fan speed to increase from the initial speed to the target speed, and perform differential integration on the target power based on the first target time to obtain the power increment.

[0069] Understandably, the first target time refers to the time it takes for the fan speed to increase from the initial speed to the target speed. This time can be obtained experimentally by recording the initial and target speeds of the fan and using appropriate measuring equipment (such as a tachometer) to monitor the speed change. The time required for the speed to increase from the initial speed to the target speed is recorded as the first target time. By integrating the target power based on this first target time, a more accurate and suitable power increment can be obtained, enabling a smooth rise in air temperature and improving the user experience.

[0070] Please see Figure 4 In some embodiments, the initial heating power is obtained through steps S401 to S402:

[0071] Step S401: When the fan is working at the target speed, adjust the heating power of the heating device, and after each adjustment of the heating power, obtain the temperature value of the air generated after the fan rotates on the heating device.

[0072] Understandably, when the fan operates at the target speed, to ensure the measured air temperature is consistent with that speed, the heating power of the heating device is adjusted and tested multiple times to determine the appropriate target power. After each adjustment, the temperature of the air generated by the fan passing through the heating device is recorded, resulting in multiple sets of different temperature values at the target speed under different heating powers. Appropriate temperature sensors or measuring devices can be used to monitor these temperature values. The data from multiple sets of heating powers and corresponding temperature values helps in determining the initial heating power. By comparing and analyzing these temperature values, temperature changes under different heating powers can be observed and evaluated. When the temperature is lower than the target temperature and persists for more than a set time threshold, the currently adjusted heating power can be considered the initial heating power.

[0073] Step S402: When the temperature value is lower than the target temperature and continues to exceed the second preset time threshold, the currently adjusted heating power is determined to be the initial heating power.

[0074] Understandably, the second preset time threshold refers to whether the temperature value can be maintained for a preset time period after adjusting the heating power. This can be used to verify the continuity of the air temperature and serve as a basis for decision-making, determining whether the heating power is suitable as the initial heating power. For example, the first preset time threshold can be set to 5 minutes. After adjusting the heating power, observe whether the air temperature can remain below the target temperature for more than 5 minutes. If the temperature value is below the target temperature and remains below it for more than 5 minutes, the currently adjusted heating power can be determined as the initial heating power.

[0075] Understandably, determining the current adjusted heating power as the initial heating power by using a temperature value lower than the target temperature and a second preset time threshold ensures that the selected initial heating power will not cause the temperature to be too high during the drying function's activation, thus avoiding exceeding the target temperature. This ensures that the temperature gradually increases at the start of drying. By setting the second preset time threshold, it avoids misjudging whether the temperature value is lower than the target temperature due to instantaneous temperature fluctuations or noise. Ensuring that the temperature consistently exceeds the time threshold eliminates interference from temporary factors, ensuring the stability and reliability of the heating process, and determining the most suitable initial heating power so that the air temperature at startup is neither too high nor too low.

[0076] Please see Figure 5 In some embodiments, the control method for a smart toilet further includes steps S501 to S502:

[0077] Step S501: In response to the smart toilet's stop heating command, the heating device is turned off;

[0078] Understandably, the "stop heating" command on a smart toilet means that after drying the buttocks, the smart toilet will stop blowing warm air onto the buttock area. This command can be sent via a stop heating button or symbol on the control panel. Users can send the command by pressing this button or selecting the corresponding symbol. When the heating function is turned off, the smart toilet will shut down the heating device, ceasing to provide heat. Alternatively, the command can be sent using the corresponding button on the remote control. It can also be controlled via a companion smartphone app.

[0079] In step S502, while turning off the heating device, the speed of the fan is controlled to gradually decrease from the target speed to zero.

[0080] Understandably, once a stop heating command is received, the smart toilet's control system gradually reduces the fan speed. This can be achieved by gradually adjusting the fan's control signal or controlling the fan driver's output. Eventually, the fan speed gradually decreases to zero, ceasing airflow and completely stopping operation. By controlling the fan speed to gradually decrease from the target speed to zero while simultaneously shutting off the smart toilet's heating device, the high-temperature heating element can gradually dissipate heat during the drying process. This gradual reduction in fan speed to zero ensures sufficient time for the heating element to cool down, guaranteeing that the heat has largely dissipated before the fan is shut off, protecting the heating element from dry burning and extending its lifespan.

[0081] Please see Figure 6In some embodiments, step S502 may include steps S601 to S602:

[0082] Step S601: Obtain the second target time for the fan speed to decrease from the target speed to zero; perform differential integration on the target speed based on the second target time to obtain the speed reduction.

[0083] As we can understand, speed reduction refers to the change in the fan's speed over a certain period of time, used to describe the degree of speed change between two adjacent time points. The speed reduction is calculated by comparing the fan's speed values at two time points and then calculating the difference between them. Assume there are two time points t1 and t2, with corresponding fan speeds V1 and V2 respectively. The speed reduction ΔV can be calculated using the following formula: ΔV = V1 - V2, where ΔV represents the speed reduction, V2 represents the fan speed at the later time point, and V1 represents the fan speed at the earlier time point. The sign of the speed reduction indicates the direction of the fan speed change. If ΔV is positive, it means the fan speed is decreasing; if ΔV is negative, it means the fan speed is increasing. When two time points t1 and t2 approach infinity, the fan speed can be reduced more smoothly. Assuming v(t1) is the fan speed at time t1, then v(t1+Δt) is the fan speed after adding a small time interval Δt at time t1. lim represents the limit operation, and the speed reduction ΔV is:

[0084] △V=lim △t [v(t1)-v(t1+△t)]

[0085] Understandably, the second target time refers to the duration it takes for the fan speed to decrease from the target speed to zero. This time can be obtained experimentally. By recording the target fan speed and using appropriate measuring equipment (such as a tachometer) to monitor its changes, the time required for the speed to decrease from the target speed to zero is recorded as the second target time. By performing a differential on the target speed based on this second target time, a more accurate and appropriate speed reduction can be obtained. This allows the fan speed to decrease smoothly through gradual adjustments, enabling the heating device to dissipate heat gradually after heating stops, extending the lifespan of the heating device, and simultaneously ensuring a stable decrease in air temperature.

[0086] Step S602: Control the fan speed to decrease from the target speed to zero according to the speed reduction, where the speed reduction is the difference between any two adjacent speeds during the fan speed adjustment process.

[0087] Understandably, the target speed is the starting point for the fan speed at which the heating process stops. Based on system requirements and control strategy, the magnitude of the speed reduction for each adjustment is determined. This can be a fixed reduction step size or an adaptive adjustment based on actual conditions. Starting from the target speed, adjustments are made gradually based on the speed reduction. After each adjustment, the fan speed will decrease accordingly. For example, if the initial speed is V... t0 The speed reduction is ΔV t Then the rotational speed of the next fan can be calculated as V. t1 =V t0 -ΔV t Next, use V t1 As the new initial speed, it is adjusted again based on the speed reduction to obtain V. t2 =V t1 -ΔV t Similarly, following the set steps, the fan speed is gradually reduced, resulting in a smooth decrease in fan speed and gradual heat dissipation from the heating device.

[0088] Understandably, by gradually reducing the fan speed from the target speed to zero using speed reduction control, a smooth temperature drop can be achieved at the end of the drying process in a smart toilet. This avoids sudden temperature changes, prevents discomfort during the drying process, and avoids excessively cold or hot conditions. The exact temperature drop rate and specific speed reduction strategy can vary depending on the design and control method of the smart toilet system. In practical applications, appropriate settings and adjustments can be made based on user needs, system characteristics, and safety requirements.

[0089] Please see Figure 7 In some embodiments, the control method for a smart toilet further includes steps S701 to S702:

[0090] Step S701: In response to the cool air command from the smart toilet, turn on the fan and record the drying time;

[0091] As you can understand, a cool air command refers to the smart toilet blowing unheated cool air to dry the buttocks. By sending a cool air command, the smart toilet's control system will activate the corresponding fan, blowing unheated air towards the user's buttocks to achieve a drying effect. This function increases user comfort and choice, especially in warmer seasons or when the user prefers cool air drying. Cool air commands for smart toilets can come from a cool air button or symbol on the control panel; users can send the command by pressing the button or selecting the corresponding symbol. Alternatively, they can send the command using the corresponding button on the remote control. Cool air control can also be achieved through a companion smartphone app. The drying time under a cool air command refers to the duration for which the smart toilet blows cool air. Smart toilets can have a built-in timer function, provided by the control unit or timer module.

[0092] Step S702: When the drying time reaches the preset duration, turn off the fan.

[0093] Understandably, the preset time is the duration for which the smart toilet blows unheated cool air. The control system uses a built-in timer to record the drying time and compares it to the preset time. When the timer reaches the preset time, it can trigger the fan to shut off, stopping the supply of cool air. By setting a preset time and turning off the fan promptly, energy can be effectively saved. This avoids unnecessary energy consumption, especially if the user forgets to turn off the drying function or the drying time is too long. Excessive drying time can lead to unnecessary dryness or discomfort. Setting a preset time and turning off the fan promptly also prevents over-drying, protecting the user's skin and comfort.

[0094] Please see Figure 8 In one specific embodiment, a schematic diagram of the drying device on a smart toilet is shown. The drying device includes:

[0095] The main control board 100, serving as the central controller, receives information from external sensors, runs algorithms, performs logical calculations, and outputs control signals. It controls the smart toilet to respond to heating commands, activating the fan at a preset initial speed and gradually increasing the fan's speed. Simultaneously, it begins heating the heating device at a preset initial heating power to increase the temperature of the air passing through the heating device. As the fan speed gradually increases, the heating power of the heating device also gradually increases from the initial power. Once the fan speed reaches the preset target speed, it obtains the target power increase achieved as the air temperature gradually reaches the target temperature, controls the fan to rotate at the target speed, and controls the heating device to heat at the target power.

[0096] The drying fan 200 uses a motor to drive the rotation of a fan wheel or blades to generate airflow. When the motor is running, the fan wheel or blades draw in surrounding air and expel it through rotation, forming an airflow. This airflow can be used for applications such as drying or ventilation. Hot air can be provided through a heating element; the heating element is typically a heat source. When the heating wire is energized or the heater is working, it heats the surrounding air and exhausts the hot air through the fan wheel or blades. Alternatively, room temperature cold air can be provided directly. The motor drives the fan wheel or blades to rotate, drawing in surrounding air and expelling room temperature air to form a cold airflow.

[0097] The drying heating wire 300 provides heat by generating resistance through the passage of current. When current passes through the drying heating wire 300, electrical energy is converted into heat energy, and the drying heating wire 300 heats up to heat the air.

[0098] The air temperature sensor 400 is located at the air outlet of the air duct and measures the temperature of the air flowing through the location of the air temperature sensor 400.

[0099] Please see Figure 9 In one specific embodiment, the drying apparatus further includes:

[0100] 500mm upper casing for the air duct, the top or upper cover of the air duct;

[0101] The bottom shell of the air duct 600 is a bottom cover of the air duct, and a drying fan 200 is installed thereon. The upper shell of the air duct 500 and the bottom shell of the air duct 600 are fixed together by snaps.

[0102] The air duct is formed between the upper shell 500 and the lower shell 600. A drying fan 200 is installed in the lower shell 600. The drying fan 200 blows out warm air heated by the heating device. A wind temperature sensor 400 is installed at the air duct outlet to measure the wind temperature and feed it back to the main control board 100. The main control board 100 controls the smart toilet to respond to the heating command. It turns on the fan on the smart toilet at a preset initial speed and controls the fan speed to gradually increase from the initial speed. At the same time as the fan turns on, the heating device on the smart toilet begins to heat at a preset initial heating power to increase the temperature of the air generated by the fan after passing through the heating device. As the fan speed gradually increases, the heating power of the heating device is controlled to gradually increase from the initial heating power. When the fan speed increases to the preset target speed, the target power of the heating device is obtained when the air temperature gradually reaches the target temperature. The fan is then controlled to rotate at a constant speed at the target speed, and the heating device is controlled to heat at the target power.

[0103] Please see Figure 10 In one specific embodiment, this is a schematic diagram of the electrical control connection of a smart toilet.

[0104] The main control MCU is a microcomputer chip that integrates a central processing unit, memory, input / output interfaces, and various peripheral functions. The power supply is connected to the main control MCU's power input pin to provide the necessary electrical energy. The drying button is connected to the main control MCU's input pin; when the drying button is pressed or released, the main control MCU detects the corresponding signal and controls the drying function to turn on or off based on the signal. The air temperature sensor is located at the air outlet of the air duct and is used to detect the temperature of the drying air. The air temperature sensor transmits the measured temperature information to the main control MCU through its connection to the main control MCU's input pin. The optocoupler and SCR control assembly are used to control the heating of the heating element. The main control MCU connects its output signal to the input of the optocoupler. When the main control MCU sends a corresponding signal, the optocoupler isolates the signal and transmits it to the SCR control assembly. Upon receiving the signal, the SCR control assembly controls the heating power of the heating element. The fan is connected to the output pin of the main control MCU. The main control MCU can control the fan's start and stop by controlling the level of the output pin. The fan provides airflow to generate airflow during the drying process. The main control MCU receives the fan speed feedback signal and adjusts the fan speed accordingly. The main control MCU can detect and control the drying button, monitor the temperature of the air temperature sensor, control the heating element, and control the fan's start and stop, thus realizing the drying function of the smart toilet.

[0105] Please see Figure 11 In a specific embodiment, this is a control timing diagram for the drying process of a smart toilet. For example... Figure 11 As shown, in stage t1, the heating power of the heating device is gradually increased according to the power increment, and the air temperature gradually rises. When the fan speed reaches the target speed, the target power increase is obtained as the air temperature gradually reaches the target temperature. The fan is then controlled to rotate at a constant speed at the target speed, and the heating device is controlled to heat at the target power, maintaining the air temperature at the target temperature. Figure 11 In stage t2, in response to the smart toilet's stop heating command, the heating device of the smart toilet is turned off. At the same time as the heating device is turned off, the speed of the control fan gradually decreases from the target speed to zero, and the air temperature gradually decreases.

[0106] Please see Figure 12 This is a logic control diagram from a control method for a smart toilet in related technologies. When drying begins, the fan starts and the heating device operates at full power simultaneously. A temperature sensor detects whether the air temperature has reached the target temperature. If the target temperature is reached, the heating power is adjusted to maintain a stable temperature. If the target temperature has not been reached, the heating device continues to operate at full power until the target temperature is reached. When drying is finished, both the fan and the heating device are turned off.

[0107] Please see Figure 13 This is another logic control diagram in the control methods of smart toilets in related technologies. When drying is started, after the fan is turned on, the heating device is turned on at full power after a 3-second delay, and the air temperature sensor detects whether the air temperature has reached the target temperature. If the air temperature reaches the target temperature, the heating power is adjusted to keep the air temperature stable; if the target temperature has not been reached, the heating device continues to operate at full power until the target temperature is reached. When drying is finished, the heating device is turned off first, and the fan is turned off after a 3-second delay.

[0108] Please see Figure 14 This is a logic control diagram of a specific embodiment provided in this application. When drying is started, the main control board determines whether it is a heating command. If it is a heating command, the fan is turned on while the fan speed is detected, and the heating device is turned on simultaneously. The heating power is adjusted according to the power increment. When the speed reaches the target speed, the target power is obtained as the air temperature gradually heats to the target temperature, and the fan is controlled to rotate at a constant speed at the target speed, and the heating device is controlled to heat at the target power. If a stop heating command is received, the heating device is turned off, and the fan speed is controlled to decrease according to the speed increment until the speed is zero and the fan is turned off. If it is not a heating command, the drying time is recorded while the fan is turned on. If the drying time reaches the preset time, the fan is turned off.

[0109] This application embodiment also provides a smart toilet that can implement the above-described control method for the smart toilet. The functional modules of the smart toilet include:

[0110] The start-up module is used to respond to the heating command of the smart toilet, turn on the fan on the smart toilet at a preset initial speed, and control the speed of the fan to gradually increase from the initial speed.

[0111] The adjustment module is used to start heating the heating device on the smart toilet at a preset initial heating power when the fan is turned on, so as to increase the temperature of the air generated by the fan after passing through the heating device. As the fan speed is gradually increased, the heating power of the heating device is controlled to gradually increase from the initial heating power.

[0112] The constant temperature module is used to obtain the target power increase of the heating power as the air temperature gradually heats up to the target temperature after the fan speed increases to the preset target speed, control the fan to rotate at a uniform speed at the target speed, and control the heating device to heat at the target power.
