In the related art, the drying function of the intelligent closestool is realized through the fan and the heating wire, and the temperature of wind generated after the fan rotates can be raised after passing through the heating wire by starting the fan and heating the heating wire. However, at present, when the intelligent closestool realizes the drying function, the wind temperature cannot be changed stably, so that a user can blow high-temperature or low-temperature wind for a short time, and the drying experience of the intelligent closestool is reduced.

The embodiment of the application provides a control method and a control device for an intelligent toilet and the intelligent toilet, and specifically, the following embodiment is used for explaining, and first describes the control method for the intelligent toilet in the embodiment of the application.
The control method of the intelligent closestool in the embodiment of the application can be explained through the following embodiment.
Fig. 1 is an optional flowchart of a control method of a smart toilet according to an embodiment of the present application, where the method in fig. 1 may include, but is not limited to, steps S101 to S103.
Step S101, responding to a heating instruction of the intelligent closestool, starting a fan on the intelligent closestool at a preset initial rotating speed, and controlling the rotating speed of the fan to gradually increase from the initial rotating speed;
the execution subject of the application is a smart toilet, in particular a processor (Central Processing Unit, CPU) on the smart toilet. In smart toilets, the processor is responsible for controlling various functions and performing various operations, such as detecting sensor data, controlling flushing, regulating temperature, etc. The processor performs decision making and operation according to the input signals and the internal state by executing a preset program and algorithm so as to realize various functions of the intelligent closestool.
It will be appreciated that the heating instructions of the intelligent toilet refer to the intelligent toilet blowing warm air to the buttocks area to achieve a drying effect when the user finishes defecating or urinating, providing a more convenient, hygienic and comfortable use experience. The heating command of the intelligent toilet may come from a heating button or symbol on the control panel, and the user may turn on or off the heating function by pressing the button or selecting a corresponding symbol when using the intelligent toilet. When the heating function is started, the intelligent closestool can enable the fan to blow out heated wind through the heating device. The heating command can also be sent by a remote control equipped with a smart toilet, using corresponding buttons on the remote control. The heating instruction control can also be performed through a matched smart phone application program.
It is understood that the preset initial rotational speed refers to the rotational speed of the blower on the intelligent toilet when the drying function is started in response to the heating command. In the use of intelligent closestool, preset initial rotational speed is set according to user's demand and design, adjusts under the prerequisite that satisfies the user and to comfort level and stoving effect requirement, opens the fan on the intelligent closestool under preset initial rotational speed, guarantees can not lead to the effect of stoving too poor because of the wind speed is too little or make the user feel uncomfortable because of initial wind speed is too big, provides quick, effective and comfortable stoving experience.
It will be appreciated that the control of the fan speed to increase gradually from the initial speed may be controlled by a software algorithm. The developed software algorithm can be integrated into a control system of the intelligent closestool, namely, the hardware and the software of the intelligent closestool are interfaced to ensure that the algorithm can control the rotating speed of the fan, and an increasing function or other algorithms can be used for controlling the increasing speed and time interval of the rotating speed of the fan.
Step S102, starting to heat a heating device on the intelligent closestool under the preset initial heating power while starting a fan so as to improve the wind temperature of wind generated after the fan rotates and passing through the heating device, and controlling the heating power of the heating device to be gradually increased from the initial heating power in the process of gradually increasing the rotating speed of the fan;
it is understood that the preset initial heating power refers to the heating power of the heating device set when the heating function of the intelligent toilet is started in response to the heating command. The preset initial heating power is set on the premise of considering user requirements and energy efficiency, so that the air temperature can quickly reach a comfortable temperature, the heating device can be prevented from being overheated, the air temperature is prevented from being too high in the drying and starting stage, and comfortable experience is provided for users.
It will be appreciated that the heating means may generate warm air which is blown by the fan to the buttocks area of the user to achieve a drying effect. The heating device is built in the structure of the toilet bowl and can be composed of an electric heating element, such as a heating wire, a heating coil or a heater. The heating device is connected with a control system of the intelligent closestool, and parameters such as heating power and the like are adjusted through the control system. The user may also control these parameters via buttons on the control panel, remote controls, or other control devices to meet the needs and preferences of the individual.
It can be understood that the wind temperature refers to a temperature value obtained by heating the wind generated after the fan rotates through the heating device, and the change of the wind temperature can be monitored in real time by using a temperature sensor or other wind temperature monitoring equipment on the intelligent closestool. Gradually increasing the speed of the fan may be achieved by controlling the current or voltage of the fan, and an incremental function or other control algorithm may be used to adjust the speed and time interval of the fan speed increase. The heating power of the control heating device is gradually increased from the initial heating power, the speed and the time interval of the increasing power can be adjusted by using an increasing function or other control algorithms, the transmission of hot air is quicker in the process of gradually increasing the rotating speed of the fan, meanwhile, the heating power is gradually increased, more heat can be provided, the air temperature of the generated air after the fan rotates is gradually increased after passing through the heating device, the overheat or supercooling of the air temperature in a short time can be avoided, the smooth change process of the slowly increased temperature is realized, and more comfortable drying experience meeting the user requirements is provided.
Step S103, after the rotating speed of the fan is increased to a preset target rotating speed, the target power to which the heating power is increased when the air temperature is gradually heated to the target temperature is obtained, the fan is controlled to rotate at a constant speed at the target rotating speed, and the heating device is controlled to heat at the target power.
It will be appreciated that the target rotational speed is a set desired fan rotational speed that causes the fan to operate at a particular rotational speed to provide the proper wind and drying effect. The intelligent toilet may provide a variety of fan speed options, such as low speed, medium speed, high speed, and the user may select an appropriate target speed based on his own needs. The intelligent toilet may provide preset drying modes, each having a specific target rotational speed and drying time. The fan is connected with the control system, the rotating speed of the fan is monitored, feedback signals are provided for the control system, and the control system can judge whether the fan reaches the target rotating speed or not according to the signals.
It will be appreciated that the target temperature is a desired temperature value set during the drying process, which can be set according to specific needs, design requirements or user preferences to provide a comfortable drying experience for the user. By adjustment and configuration in a system control parameter setting, thermostat or control panel. The drying function of the intelligent closestool can provide a plurality of temperature options so as to meet the requirements of different users. The target temperature may be between 30 degrees celsius and 40 degrees celsius, suitable for users that are sensitive to temperature or interested in lower warmth; can be between 40 ℃ and 50 ℃, is suitable for most users, and provides moderate warmth and comfort; and may be between 50 degrees celsius and 60 degrees celsius, suitable for users desiring higher temperatures and stronger drying effects.
It is understood that the target power is a power value to which the heating power of the heating device is increased when the wind temperature is gradually heated to the target temperature after the fan speed reaches the target speed. By setting a suitable target power for the heating means after the desired target rotational speed has been reached, it can be ensured that the air inside the toilet is sufficiently and exactly supplied with energy. By setting the target power, the wind temperature can be ensured to be maintained in a stable state, and the accurate control of the wind temperature and the rotating speed of the fan is realized.
It will be appreciated that controlling the fan to rotate at a constant speed at a target speed may be achieved by monitoring the speed of the fan and controlling it to rotate at a constant speed at the target speed using a suitable controller, such as a PID controller. The controller may adjust the output power of the blower according to a difference between the actual rotational speed and the target rotational speed to stabilize the rotational speed around the target rotational speed. The heating device is controlled to heat at a target power, and a controller may also be used to monitor and control the heating power of the heating device. The controller may adjust the output of the heating device according to a difference between the actual power and the target power to stabilize the heating power at the target power. The fan is controlled to rotate at a constant speed under the target rotating speed, the heating device is controlled to heat under the target power, stable output heat is provided, and the intelligent closestool can blow out stable air temperature by combining with the constant speed air speed, so that comfortable and stable user drying experience is provided.
According to the method and the device, the fan on the intelligent closestool is started at the preset initial rotating speed in response to the heating instruction of the intelligent closestool, the rotating speed of the fan is controlled to gradually increase from the initial rotating speed, the heating device on the intelligent closestool is started at the preset initial heating power when the fan is started, so that the air temperature generated after the fan rotates in the heating start stage is not too high after passing through the heating device, the heating power of the heating device is controlled to gradually increase from the initial heating power in the process of gradually increasing the rotating speed of the fan, the heating power of the heating device is gradually increased each time by adding a tiny change amount, the air temperature generated after the fan rotates gradually rises to the target temperature through the air temperature after the heating device, the slower temperature rising change is realized, the temperature is not suddenly increased, the target power to which the heating power is increased when the rotating speed of the fan is increased to the preset target rotating speed is obtained, the fan is controlled to rotate at the uniform speed under the target rotating speed, the target power is controlled to heat the air temperature, the air temperature is maintained at the target temperature, the air temperature can be heated to the target temperature through the gradual increase of the air temperature, and the intelligent closestool is controlled to be heated, and the temperature change is realized through the gradual increase of the wind temperature increasing speed after the fan.
Referring to fig. 2, in some embodiments, step S102 may include steps S201 to S202:
step S201, obtaining a preset power increment, wherein the power increment is a difference value of any two adjacent heating powers in a heating power adjustment process, and the power increment is determined based on a target power;
it is understood that the power increment refers to the amount of change in heating power over a period of time, and is used to describe the degree of change in power between two adjacent points in the heating system. The power increment is calculated by comparing the heating power values at two time points and then calculating the difference between them. Assuming that two time points t1 and t2 are provided, the corresponding heating power values are P1 and P2, respectively. The power increment Δp may be calculated by the following formula: Δp=p2—p1, where Δp represents a power increment, P2 represents heating power at a later point in time, and P1 represents heating power at a previous point in time. When two time points t1 and t2 approach infinity, the power value can be controlled to increase more steadily, assuming that P (t 1) is the heating power value at time t1, P (t1+ [ delta ] t) is the heating power value after a small time interval [ delta ] t is added at time t1, lim represents the operation of taking the limit, and the power increment [ delta ] P is:
△P＝lim △t [p(t1+△t)-p(t1)]
It will be appreciated that the sign of the power increment indicates the direction of change of power. If the value of ΔP is positive, this indicates an increase in heating power; if the value of ΔP is negative, this indicates a decrease in heating power. The power delta has an important role in the control system and can be used to monitor and regulate power changes during heating. By controlling the magnitude and rate of change of the power delta, control of the stability and responsiveness of the heating system can be achieved.
It is understood that the target power is a value to which the heating power of the heating device is increased when the wind temperature is gradually heated to the target temperature after the fan speed reaches the target speed. After the rotating speed of the fan reaches the expected target rotating speed, the wind speed reaches a stable state, and the target power of the heating device is set, so that the air in the closestool can be ensured to be supplied with enough and proper energy, and the intelligent closestool can blow out the wind with stable temperature and speed. By setting the target power, the wind temperature can be ensured to be maintained in a stable state, and the accurate control of the wind temperature and the wind speed is realized. The power increment is determined based on the target power, and in the drying application of the actual intelligent closestool, the heating process can be better controlled by determining the power increment based on the target power, so that the heating power is adjusted around the target power, the overlarge power fluctuation is avoided, the stability of the heating process is maintained, and the control requirement on the stable rise of the wind temperature is met.
Step S202, heating power of the heating device is controlled to be gradually increased from initial heating power according to the power increment.
It can be appreciated that the initial heating power is the starting point of the heating process, so that the air temperature can quickly reach a comfortable temperature, the overheating of the heating device can be prevented, the air temperature is prevented from being too high in the drying and starting stage, and comfortable experience is provided for users. According to the system requirements and the control strategy, the power increment size of each adjustment is determined, and the power increment size can be a fixed increment step size or can be adaptively adjusted according to actual conditions. Starting from the initial heating power, a gradual adjustment is made according to the power increment. After each adjustment, the heating power is correspondingly increased. For example, if the initial power is P t0 The power increment is delta P t Then the next power value may be calculated as P t1 ＝P t0 +ΔP t . Next, P is used t1 As new initial power, the power increment is adjusted again to obtain P t2 ＝P t1 +ΔP t . And so on, when the rotating speed of the fan is increased to the target rotating speed, the heating power is gradually increased according to the set steps, more heat is gradually provided, and the air temperature is stably increased.
It can be understood that when the rotating speed of the fan is increased to the target rotating speed, the heating power of the heating device is controlled to be gradually increased from the initial heating power according to the power increment, the provided heat is gradually increased, the stable rising of the air temperature of the intelligent closestool drying function can be realized, the abrupt change of the air temperature can be avoided, uncomfortable heat sensation is prevented from being generated in the drying process, the overheating phenomenon in the drying process is avoided, and the risk of scalding is reduced. If the wind temperature suddenly rises or reaches an excessively high temperature, scald may be caused to the skin of the user. By gradually increasing the heating power, the wind temperature can be gradually increased, so that the wind temperature can be operated in a safe range, and the skin of a user is protected. Meanwhile, the stable air temperature rise can provide a softer and more comfortable drying effect.
Referring to fig. 3, in some embodiments, the power increment is obtained through steps S301 to S303:
step S301, when the fan works at the target rotating speed, adjusting the heating power of the heating device, and after adjusting the heating power once, acquiring the temperature value of wind generated after the fan rotates on the heating device;
it will be appreciated that when the fan is operating at the target speed, it is ensured that the measured wind temperature is that at the target speed, and that the heating power of the heating device is adjusted for a plurality of test recordings in order to determine the appropriate target power. After the heating power is adjusted each time, the temperature value of wind generated after the fan on the heating device rotates is obtained, and a plurality of groups of different temperature values under different heating powers and at the target rotating speed can be obtained. The target power in the steady state is determined according to the plurality of groups of heating power and the corresponding temperature value data, so that stable temperature output can be realized under the target rotating speed of the fan, and the air temperature state of the output target temperature is maintained. By comparing and analyzing the temperature values of the plurality of groups, the temperature change condition under different heating powers can be observed and estimated. When the temperature value reaches the target temperature and continues to exceed the set time threshold, the currently adjusted heating power may be determined to be the target power.
Step S302, when the temperature value reaches the target temperature and continuously exceeds a first preset time threshold, determining the currently adjusted heating power as target power;
it is understood that the first preset time threshold refers to whether the temperature value can last more than a preset time period after adjusting the heating power, and can be used to verify the persistence of the wind temperature and be used as a basis for decision to determine whether the heating power is suitable as the target power. The proper heating power can provide stable heat for the air in the closestool, and when the rotating speed of the fan reaches the target rotating speed, the intelligent closestool is maintained to blow out stable air temperature. For example, the first preset time threshold is set to 5 minutes. After adjusting the heating power, it was observed whether the air temperature could reach the target temperature for more than 5 minutes. If the temperature value reaches the target temperature and lasts for more than 5 minutes, the currently adjusted heating power may be determined to be the target power.
It can be appreciated that the current adjusted heating power is determined to be the target power by the temperature value reaching the target temperature and the first preset time threshold, the wind temperature of the drying function can be ensured to be effective and can be maintained for a period of time in a stable state. By setting the first preset time threshold, whether the temperature value reaches the target temperature or not due to instantaneous temperature fluctuation or noise can be prevented from being misjudged, the condition that the temperature continuously exceeds the first preset time threshold can be ensured, the interference of temporary factors can be eliminated, the stability and the reliability of the heating process are ensured, and the most suitable target power is determined.
Step S303, a first target time when the rotating speed of the fan is increased from the initial rotating speed to the target rotating speed is obtained, and the target power is subjected to calculus based on the first target time to obtain a power increment.
It is understood that the first target time refers to a period of time during which the rotational speed of the blower increases from the initial rotational speed to the target rotational speed. The time for increasing the rotational speed of the fan to the target rotational speed can be obtained through experimental measurement, the initial rotational speed and the target rotational speed of the fan can be recorded, the change of the rotational speed of the fan is monitored by using proper measuring equipment (such as a tachometer), and the required time is recorded to enable the rotational speed to be increased from the initial rotational speed to the target rotational speed, namely the first target time. By performing calculus on the target power based on the first target time, a proper power increment can be obtained more accurately, so that the wind temperature can be stably increased, and the experience of a user during use is improved.
Referring to fig. 4, in some embodiments, the initial heating power is obtained through steps S401 to S402:
step S401, when the fan works at a target rotating speed, adjusting the heating power of the heating device, and after adjusting the heating power once, acquiring the temperature value of wind generated after the fan rotates on the heating device;
It can be understood that when the fan works at the target rotating speed, the measured air temperature is guaranteed to be the air temperature at the target rotating speed, and the heating power of the heating device is adjusted to carry out test records for a plurality of times so as to determine the proper target power. After the heating power is adjusted each time, the temperature value of wind generated after the fan on the heating device rotates is obtained, and a plurality of groups of different temperature values under different heating powers and at the target rotating speed can be obtained. A suitable temperature sensor or measuring device may be used to monitor the temperature value. The initial heating power is facilitated according to the plurality of groups of heating power and the corresponding temperature value data, and the temperature change condition under different heating powers can be observed and estimated through comparison and analysis of the plurality of groups of temperature values. When the temperature value is lower than the target temperature and continues to exceed the set time threshold, the currently adjusted heating power may be determined to be the initial heating power.
In step S402, when the temperature value is lower than the target temperature and continuously exceeds the second preset time threshold, it is determined that the currently adjusted heating power is the initial heating power.
It will be appreciated that the second preset time threshold refers to whether, after adjusting the heating power, the temperature value is observed to be able to last for more than a preset period of time, and can be used to verify the persistence of the wind temperature and be used as a basis for decision to determine whether the heating power is suitable as the initial heating power. For example, the first preset time threshold is set to 5 minutes. After adjusting the heating power, it was observed whether the wind temperature could be lower than the target temperature for more than 5 minutes. If the temperature value is lower than the target temperature for more than 5 minutes, the currently adjusted heating power may be determined to be the initial heating power.
It will be appreciated that by determining that the currently adjusted heating power is the initial heating power by the temperature value being lower than the target temperature and the second preset time threshold, it is possible to ensure that the selected initial heating power does not cause the temperature to be too high during the drying function on period, to avoid exceeding the target temperature, and to ensure that the temperature gradually increases at the start of drying. By setting the second preset time threshold, it is possible to avoid misjudging whether the temperature value is lower than the target temperature due to instantaneous temperature fluctuation or noise, ensure that the temperature continuously exceeds the time threshold, eliminate the interference of temporary factors, ensure the stability and reliability of the heating process, and determine the most suitable initial heating power, so that the air temperature at the time of opening is not too high or too low.
Referring to fig. 5, in some embodiments, the control method of the intelligent toilet further includes steps S501 to S502:
step S501, responding to a heating stopping instruction of the intelligent closestool, and turning off a heating device;
it will be appreciated that the instruction to stop heating of the intelligent toilet means that the intelligent toilet stops blowing warm air to the buttocks region after the buttocks are dried. The stop heating command of the intelligent closestool can come from a stop heating button or a symbol on the control panel, and a user can send the stop heating command by pressing the button or selecting the corresponding symbol when using the intelligent closestool. When the heating function is closed, the intelligent closestool can close the heating device, and the heating device does not provide heat. The heating stop command can also be sent by a remote control equipped with a smart toilet, using a corresponding button on the remote control. The control of the heating stopping instruction can also be performed through a matched intelligent mobile phone application program.
In step S502, the rotation speed of the fan is controlled to start gradually decreasing from the target rotation speed to zero while the heating device is turned off.
It will be appreciated that upon receipt of the stop heating command, the control system of the intelligent toilet begins to gradually decrease the rotational speed of the blower, either by gradually adjusting the control signal to the blower or controlling the output of the blower driver. Finally, the rotating speed of the fan is gradually reduced to zero, the generation of wind flow is stopped, and the fan completely stops running. The intelligent closestool is characterized in that the fan is controlled to rotate at the same time of closing the heating device of the intelligent closestool, the rotating speed of the fan is controlled to gradually decrease to zero from the target rotating speed, so that the heating device with higher temperature gradually dissipates heat in the drying end stage, the fan closing mode of gradually decreasing the rotating speed of the fan to zero can ensure that the heating device has enough time for cooling, the heat of the heating device is basically dissipated before the fan is closed, the heating device is protected from dry burning, and the service life of the heating device is prolonged.
Referring to fig. 6, in some embodiments, step S502 may include steps S601 to S602:
step S601, obtaining a second target time when the rotating speed of the fan is reduced to zero from the target rotating speed, and performing calculus on the target rotating speed based on the second target time to obtain rotating speed reduction;
It is understood that the rotation speed decrement refers to a change amount of the rotation speed of the blower within a certain period of time, and is used to describe a degree of change in the rotation speed between two adjacent time points in the blower. The rotational speed reduction is calculated by comparing the rotational speed values of the fans at two points in time and then calculating the difference therebetween. Assuming that two time points t1 and t2 are provided, the corresponding rotational speeds of the fans are V1 and V2 respectively. The rotation speed decrement Δv can be calculated by the following formula: Δv=v1—v2, where Δv represents a rotational speed decrement, V2 represents a rotational speed of the blower at a later point in time, and V1 represents a rotational speed of the blower at a previous point in time. The sign of the speed reduction indicates the direction of change of the fan speed. If the value of DeltaV is positive, the rotating speed of the fan is reduced; if the value of DeltaV is negative, this indicates an increase in the rotational speed of the fan. When two time points t1 and t2 approach infinity, the rotation speed of the fan can be controlled to be reduced more stably, and assuming that V (t 1) is the rotation speed value of the fan at the time t1, V (t1+ [ delta ] t) is the rotation speed value of the fan after the small time interval [ delta ] t is increased at the time t1, lim is the operation taking limit, and the rotation speed decrement [ delta ] V is:
△V＝lim △t [v(t1)-v(t1+△t)]
it is understood that the second target time refers to a period of time during which the rotational speed of the blower decreases from the target rotational speed to zero. The time for the speed of the fan to decrease from the target speed to zero can be obtained by experimental measurements, the speed of the fan can be reduced from the target speed to zero by recording the target speed of the fan, and monitoring the change in speed of the fan using a suitable measuring device (e.g., a tachometer), recording the time required to decrease the speed from the target speed to zero, i.e., the second target time. Through carrying out the calculus to the target rotational speed based on the second target time, can obtain suitable rotational speed decrement more accurately for the rotational speed of fan can realize steadily falling under the gradual adjustment of rotational speed decrement, makes heating device dispel the heat gradually after stopping heating, prolongs heating device's life, makes the steady decline of wind temperature simultaneously.
Step S602, the rotating speed of the fan is reduced to zero from the target rotating speed according to the rotating speed reduction control, wherein the rotating speed reduction is the difference value of any two adjacent rotating speeds in the rotating speed adjustment process of the fan.
It will be appreciated that the target rotational speed is the starting point for the fan rotational speed to stop the heating process. According to the system requirements and the control strategy, the rotating speed decrement of each adjustment is determined, and the rotating speed decrement can be a fixed decrement step length or can be adaptively adjusted according to actual conditions. From the target rotation speed, the gradual adjustment is performed according to the rotation speed reduction. After each adjustment, the rotation speed of the fan is correspondingly reduced. For example, if the initial rotational speed is V t0 The rotation speed is reduced to DeltaV t Then the rotational speed value of the next fan can be calculated as V t1 ＝V t0 -ΔV t . Next, use V t1 As a new initial rotation speed, the rotation speed is adjusted again according to the reduction of the rotation speed to obtain V t2 ＝V t1 -ΔV t . And the like, gradually reducing the rotating speed of the fan according to the set steps, so that the rotating speed of the fan is steadily reduced, and the heating device gradually dissipates heat.
It can be understood that the rotation speed of the fan is gradually reduced to zero from the target rotation speed according to the rotation speed reduction control, so that the stable reduction of the air temperature at the drying end stage of the intelligent closestool can be realized, the abrupt change of the air temperature can be avoided, the uncomfortable feeling in the drying process is prevented, and the supercooling or overheat phenomenon in the drying process is avoided. The exact wind temperature drop rate and specific speed reduction strategy may vary depending on the design and control of the intelligent toilet system. In practical application, the device can be properly set and adjusted according to the requirements of users, the characteristics of the system and the safety requirements.
Referring to fig. 7, in some embodiments, the control method of the intelligent toilet further includes steps S701 to S702:
step S701, responding to a cold air instruction of the intelligent closestool, starting a fan, and recording drying time;
it can be understood that the cold air instruction means that the intelligent closestool blows unheated cold air to blow the buttocks to dry. Through sending cold wind instruction, intelligent closestool's control system can start corresponding fan, blows unheated air to user's buttock to reach the effect of weather. Such functionality may increase user comfort and selectivity, especially in warm seasons or when the user prefers cold air drying. The cold air command of the intelligent closestool can come from a cold air button or a symbol on the control panel, and a user can send the cold air command by pressing the button or selecting the corresponding symbol when using the intelligent closestool. The cold air instruction can also be sent by a remote controller provided with an intelligent closestool and using corresponding buttons on the remote controller. And the cold air instruction control can be performed through a matched intelligent mobile phone application program. The drying time under the cold air instruction refers to the time for the intelligent closestool to blow out cold air. The intelligent toilet may have a built-in timing function, which may be provided by a control unit or a timer module.
In step S702, when the drying time reaches the preset duration, the fan is turned off.
It is understood that the preset duration is a duration during which the intelligent toilet blows unheated cool air. The control system may use a built-in timer to record the drying time and compare it with a preset duration. When the time recorded by the timer reaches the preset duration, the operation of closing the fan can be triggered to stop providing cold air. By setting the preset time length and closing the fan in time, energy can be effectively saved. Unnecessary energy consumption is avoided, especially in case the user forgets to turn off the drying function or the time is too long. Too long a drying time may cause unnecessary drying or discomfort. By setting the preset time length and closing the fan in time, excessive drying can be avoided, and the skin and comfort of a user are protected.
