Description

Technical Field

[0001] This application relates to the field of toilet control technology, and in particular to a method, control device and toilet for controlling the noise of a toilet. Background Technology

[0002] During toilet use, the sounds of water impacting when flushing, the sound of the lid opening and closing, and the noise of parts operating can easily disturb family members' rest during quiet times such as night and early morning, or cause psychological discomfort to users who are not fully awake. This has led to the demand for quiet toilets.

[0003] Related technologies reduce the noise of toilet operation by optimizing hardware, such as using a siphon flushing structure to reduce the sound of water flow impact.

[0004] In terms of software control, the silent control of toilets relies more on manual triggering. Users need to actively activate the silent function through buttons on the toilet or remote control. Moreover, the silent parameters of the silent function are all preset fixed parameters. This not only depends on the user's active control, but also easily leads to the toilet's cleaning effect in silent mode failing to meet the user's actual needs, resulting in poor adaptability.

[0005] The patent "A Silent Toilet," publication number CN222183574U, published on December 17, 2024, discloses a design including a flow regulating component and a detector. The flow regulating component is connected to the water inlet pipe and can control the water inlet speed based on the electrical signal from the detector. This allows the toilet to reduce water flow during off-peak hours to lower noise and improve user experience, avoiding disturbance to the user's rest. During peak hours, the water flow speed is increased to ensure the user's water needs are met. This solution controls the water flow speed based on whether the toilet is in use, achieving a silent effect when the user is not actively using it. However, this solution cannot meet the silent requirements of a home environment or when the user is not fully awake.

[0006] The patent "Method, Device, Equipment and Storage Medium for Controlling the Working Mode of Water Discharge Equipment", publication number: CN118170048A, publication date: June 11, 2024, specifically discloses a method for controlling the operation of water discharge equipment by acquiring preset working conditions; determining the working mode of the water discharge equipment based on the preset working conditions; and controlling the operation of the water discharge equipment according to module operation instructions in the working mode. The module operation instructions are used to control the operation of each working module in the water discharge equipment. This solution controls the operation of working modules in different states with a fixed operating power, which also presents the problem of not being able to simultaneously achieve both quiet operation and cleaning effect. Summary of the Invention

[0007] This application addresses the problem in existing toilet noise control technologies that fail to balance noise reduction and cleaning effectiveness. It provides a toilet noise control method, control device, and toilet. By calculating a noise reduction coefficient based on the current state data of the toilet, the noise reduction amplitude changes with the toilet's usage status, lid-open status, and other states. This allows for different amplitude actions to be performed in different toilet states, resulting in a higher cleaning effect when the toilet is in use and used for extended periods, thus achieving a balance between cleaning effectiveness and noise reduction.

[0008] To achieve the above-mentioned technical objectives, this application provides a technical solution: a toilet noise control method, comprising the following steps: in response to a noise signal, calculating a noise amplitude coefficient based on the current state data of the toilet; obtaining the noise reduction action amplitude of the toilet based on the noise amplitude coefficient and the initial action amplitude of the toilet; and in response to a control signal, executing a toilet action corresponding to the control signal based on the noise reduction action amplitude of the toilet.

[0009] Furthermore, it also includes: obtaining the illuminance duration when the illuminance value is less than or equal to a preset illuminance threshold, obtaining the first duration when the human body recognition result is in an unmanned state, and outputting a mute signal when the illuminance duration reaches the preset illuminance duration or / and the first duration reaches the first preset duration.

[0010] Furthermore, it also includes: obtaining the current time point, and if the current time point is within the silent time interval, then outputting a silent signal.

[0011] Furthermore, the step of calculating the noise level coefficient based on the current state data of the toilet includes: obtaining the second duration of the human body recognition result indicating that someone is present, and calculating the noise level coefficient based on the second duration and the current state data of the toilet.

[0012] Furthermore, the step of calculating the silence amplitude coefficient based on the current state data of the toilet in response to the silence signal includes: in response to the manual silence signal, obtaining a second duration when the human body recognition result indicates that someone is present, and calculating the silence amplitude coefficient based on the second duration and the current state data of the toilet; in response to the automatic silence signal, performing a demand judgment based on real-time environmental data and the human body recognition result, obtaining a third duration when the demand judgment result indicates that the demand is adjusted, and calculating the silence amplitude coefficient based on the third duration and the current state data of the toilet.

[0013] Furthermore, the calculation of the noise level coefficient based on the current state data of the toilet includes: obtaining the duration of the sitting state based on the sitting state of the toilet, obtaining the duration of the open state based on the open state of the toilet; calculating the noise level coefficient based on the duration of the sitting state; or, calculating the noise level coefficient based on the duration of the open state.

[0014] Furthermore, the calculation of the noise level coefficient based on the current state data of the toilet also includes: calculating the noise level coefficient based on the duration of the sitting state and the number of times the toilet is washed.

[0015] Furthermore, it also includes: implementing a deodorization ban in response to a seating signal.

[0016] Furthermore, the calculation of the noise level coefficient based on the current state data of the toilet also includes: calculating the noise level coefficient based on the open state of the toilet lid, the state of the auxiliary factors, and the usage state when the toilet is finished using it.

[0017] Furthermore, the calculation of the noise level coefficient based on the current state data of the toilet also includes: obtaining the noise level coefficient of the toilet's self-cleaning mode based on the toilet's open state.

[0018] Another technical solution provided in this application is a toilet noise control device for implementing the method described above, comprising: a state recognition unit for acquiring current state data of the toilet; an amplitude calculation unit for calculating a noise amplitude coefficient based on the current state data of the toilet, and acquiring the noise reduction action amplitude of the toilet based on the noise amplitude coefficient and the initial action amplitude of the toilet; and an execution unit for executing the toilet action corresponding to the control signal based on the noise reduction action amplitude of the toilet.

[0019] Another technical solution provided in this application is a toilet, including a toilet body and the aforementioned toilet noise control device.

[0020] The beneficial effects of this application are as follows: 1. When entering silent mode, the user's silent needs are determined based on the current status data of the toilet to obtain a silent amplitude coefficient. The amplitude of each movement of the toilet is dynamically adjusted according to the silent amplitude coefficient, thereby realizing that the movement amplitude of the toilet is dynamically adjusted according to the user's silent needs, improving the adaptability of the silent state, taking into account both silent needs and user needs, and enhancing the user experience.

[0021] 2. When the toilet senses the user sitting down, it will activate the deodorization shutdown function to avoid interference from the dual-program operation. Since the washing program will reduce the noise level, the noise of the deodorization fan can be reduced to compensate for the increased operating noise to improve the cleaning effect. This will ensure the toilet is clean while minimizing the noise of the toilet.

[0022] 3. Calculate the noise level coefficient based on the toilet's open state, auxiliary factor state, and usage state after use to balance the toilet's cleaning effect and noise reduction effect. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description of this application is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely one preferred embodiment of this application and are only used to explain this application. They do not limit the scope of protection of this application. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] like Figure 1 As shown, the toilet noise control method includes the following steps:

[0030] In response to a silence signal, a silence amplitude coefficient is calculated based on the current state data of the toilet.

[0031] The noise reduction amplitude of the toilet is obtained based on the noise reduction amplitude coefficient and the initial movement amplitude of the toilet.

[0032] In response to a control signal, the toilet performs actions corresponding to the control signal based on the magnitude of the toilet's silent movement.

[0033] In this embodiment, when entering silent mode, the user's silent needs are determined based on the current state data of the toilet to obtain a silent amplitude coefficient. The amplitude of each movement of the toilet is dynamically adjusted according to the silent amplitude coefficient, thereby realizing that the movement amplitude of the toilet is dynamically adjusted according to the user's silent needs, improving the adaptability of the silent state, taking into account both silent needs and user usage needs, and enhancing the user experience.

[0034] As an embodiment of this application, the toilet noise control method further includes:

[0035] When environmental data and / or human body recognition data meet the preset mute conditions, a mute signal is output.

[0036] At this time, the toilet is equipped with environmental sensors and human body recognition sensors to obtain environmental data and human body recognition results.

[0037] In some feasible cases, the environmental sensor is an illuminance sensor, and the environmental data includes illuminance values ​​and duration of illuminance. The human body recognition sensor is one or more of an infrared sensor, microwave sensor, button sensor, and seating sensor, and the human body recognition data includes the human body recognition result and duration. In this case, when the environmental data and / or the human body recognition data meet the preset mute conditions, the output mute signal includes:

[0038] The system acquires the duration of illumination when the illuminance value is less than or equal to a preset illuminance threshold, acquires the first duration of human body recognition when no one is present, and outputs a mute signal when the illuminance duration reaches the preset illuminance duration or / and the first duration reaches the first preset duration.

[0039] At this time, the preset silent conditions include a preset illuminance duration and / or a first preset duration. When the illuminance value is less than or equal to the preset illuminance threshold, it is considered that the current environment is dark. When the environment is dark and / or unoccupied, the toilet enters silent mode, and the amplitude of subsequent movements of the toilet is adjusted according to the current state data of the toilet. It can be understood that the preset illuminance threshold can be the maximum illuminance value in a dark environment or the minimum illuminance value in a bright environment. When the illuminance value is less than the preset illuminance threshold, the current environment is considered dark; when the illuminance value is greater than the preset illuminance threshold, the current environment is considered bright; when the illuminance value is equal to the preset illuminance threshold, the current environment is determined to be either dark or bright based on whether the preset illuminance threshold represents the maximum illuminance value in a dark environment or the minimum illuminance value in a bright environment.

[0040] When outputting a silence signal based on environmental data, the silence amplitude coefficient is calculated based on the current state data of the toilet, including:

[0041] The noise reduction coefficient is obtained based on the usage time of the toilet under the current usage state and the preset amplitude influence relationship.

[0042] Upon outputting a silence signal based on environmental data, the toilet enters silent mode. The silence level coefficient of silent mode is adjusted according to the usage time of the toilet. Since the longer the user uses the toilet, the greater the risk of contaminant residue and bacterial growth, the longer the usage time, the more thorough the cleaning may be required after use. Therefore, a preset influence relationship is established based on the inverse correlation between usage time and the silence level coefficient: the longer the usage time, the lower the silence level coefficient and the smaller the change in movement amplitude. This ensures that the cleaning effect is not insufficient due to the reduced movement amplitude of the toilet in silent mode. The silence adjustment is based on meeting the user's needs, ensuring the effective cleaning of the toilet.

[0043] Understandably, usage status can be determined using one or more sensors, such as microwave sensors or seat sensors. For example, when the reflected microwave signal decreases in the direction of the toilet wall, it is assumed that there is liquid flow on the toilet wall, thus distinguishing the user's usage status and avoiding overlooking usage when the user is neither seated nor has the toilet seat opened. Of course, in toilets with an automatic seat opening function, the seat opening time and seat time can also be used as the user's usage time, and the noise reduction coefficient can be dynamically selected based on a preset amplitude influence relationship according to the seat time and seat opening time.

[0044] It should be noted that the noise level is at its maximum when the toilet is not in use. When environmental conditions do not meet the preset noise levels, the silent mode will exit, automatically entering and exiting silent mode to improve user comfort.

[0045] Similarly, when outputting a silence signal based on human body recognition data, the silence amplitude coefficient is calculated based on the current state data of the toilet, including:

[0046] The noise level coefficient is calculated based on the open position of the toilet seat.

[0047] For example, when a toilet with a timed disinfection program is used, the movement of the toilet corresponding to the timed disinfection program is adjusted according to the current open state of the toilet when no one is present. This reduces the noise generated by the toilet's movement while performing timed disinfection, thus achieving a balance between the needs of use and the need for quiet operation.

[0048] It's understandable that the sound produced by a toilet varies depending on its position. For example, the flushing sound differs depending on whether the toilet lid is closed, partially open, or fully open. Some toilets also disinfect the seat surface during sterilization, requiring the seat to be partially or fully open. In this case, the toilet lid also needs to be open accordingly. The noise reduction coefficient is calculated based on the toilet's current lid position, ensuring that the noise reduction amplitude when the toilet lid is open is less than when it's closed. This allows the noise reduction amplitude to adapt to the toilet's actual position, improving the adaptability of the adjustment and preventing excessive reduction in noise reduction that could decrease the toilet's cleaning effect. This balances the needs of both toilet use and quiet operation.

[0049] At this time, the noise level is at its maximum when the toilet lid is fully open. This allows the system to adjust the timing of the cleaning process based on whether the user is present and the toilet lid's open position, even during the day, preventing disturbance to the user while they are resting. When the human body recognition data does not meet the preset noise conditions, the system exits silent mode, automatically entering and exiting silent mode to improve user comfort.

[0050] Therefore, calculating the noise level coefficient based on the current state data of the toilet also includes:

[0051] The noise level coefficient of the toilet's self-cleaning mode is obtained based on the toilet's open position.

[0052] It should be noted that the control signal for the toilet when unoccupied comes from a preset program, such as a user-defined program that runs at a fixed time or a timed program. This allows the toilet to adjust the self-cleaning motion according to the toilet's status when it is in self-cleaning mode, automatically entering a silent mode to improve the user experience. It also reduces the noise level when the lid is closed to avoid unnecessary reduction in cleaning effort.

[0053] Understandably, when a user manually selects to enter silent mode, the system also responds to the silent signal and calculates the silent amplitude coefficient based on the current status data of the toilet.

[0054] When both environmental data and human body recognition data are used to output a mute signal, the mute signal will only be output if both environmental data and human body recognition data meet the preset mute conditions. At this time, the mute amplitude coefficient will be dynamically adjusted according to the open state of the toilet seat. When either environmental data or human body recognition data does not meet the preset mute conditions, the mute mode will be exited, realizing automatic entry and exit of the mute mode.

[0055] In other embodiments, the environmental data may also include ambient sound data, and the determination of whether to enter silent mode is made based on the ambient sound data and / or illuminance values, so that silent mode can be automatically entered when the user is resting during the day.

[0056] In some other embodiments, after entering silent mode based on either environmental data or human body recognition data meeting preset silent conditions, a silent amplitude coefficient is dynamically selected based on the other type of data. For example, if environmental data meets preset silent conditions, silent mode is entered, and a silent amplitude coefficient is selected based on a first duration of human body recognition data; the longer the first duration, the larger the silent amplitude coefficient. Conversely, if environmental data does not meet preset silent conditions, silent mode is exited. When entering silent mode based on human body recognition data meeting preset silent conditions, a silent amplitude coefficient is selected based on environmental data; the more the environmental data resembles a quiet, resting environment, the larger the silent amplitude coefficient.

[0057] In other feasible cases, methods for controlling toilet noise also include:

[0058] Get the current time point. If the current time point is within the silent time interval, output a silent signal.

[0059] In toilets with timer functions, where the current time can be set or known via a mini-program, Bluetooth, or a microcontroller's internal timer, if a preset silent time interval is provided, the device will automatically enter silent mode when the current time falls within that interval. The silent time interval can be a user-defined time, a preset time based on experience (e.g., 10 PM to 6 AM the next day), or a self-adjusted time based on user usage periods, such as using the period of least frequent use as the silent time interval.

[0060] Understandably, a mute signal can be output using environmental data, human body recognition data, user's mute operation actions, or any combination of the current time point to adapt to different user needs.

[0061] As a second embodiment of this application, the difference from the first embodiment is that when the environmental data and human body recognition data meet the preset silence conditions, a silent mode is entered. After entering silent mode, if the human body recognition data no longer meets the preset silence conditions (when the state changes from unoccupied to occupied), the silent mode is not exited. Instead, a silence amplitude coefficient is calculated based on the second duration of the occupied state and the current state data of the toilet. At this time, calculating the silence amplitude coefficient based on the current state data of the toilet includes:

[0062] The second duration of the human body recognition result is obtained when someone is present. The noise level coefficient is calculated based on the second duration and the current state data of the toilet.

[0063] In this embodiment, by reasonably adjusting the noise level coefficient according to the second duration when someone is present in the silent mode, the impact of the toilet cleaning sound on other family members in the home environment is reduced, and the cleaning action amplitude can be reasonably adjusted according to the cleaning force required.

[0064] It should be noted that when the human body recognition result is no one, the second duration is 0, the noise level coefficient can be the maximum value, and it can also be adjusted according to the current status data of the toilet. That is, in toilets with timed cleaning, the noise level coefficient is further adjusted according to the open state of the toilet lid.

[0065] As another example of this embodiment, the toilet noise control method further includes:

[0066] When the preset mute conditions are met based on environmental data and human body recognition data, an automatic mute signal is output.

[0067] Output a manual mute signal based on the user's mute action;

[0068] In response to a manual mute signal, the second duration of the human body recognition result indicating that someone is present is obtained, and the mute amplitude coefficient is calculated based on the second duration and the current state data of the toilet.

[0069] In response to the automatic mute signal, a demand judgment is performed based on real-time environmental data and human body recognition results. The demand judgment result is the third duration of the demand adjustment state. The mute amplitude coefficient is calculated based on the third duration and the current state data of the toilet.

[0070] In this scenario, the mute signal includes both automatic and manual mute signals. When the user manually triggers the mute mode, a manual mute signal is output. At this time, the mute amplitude coefficient is obtained based on real-time human body recognition results and the current state data of the toilet. Conversely, when the user automatically enters mute mode after the environmental and human body recognition data meet the preset mute conditions, an automatic mute signal is output. In this case, a real-time demand judgment is performed based on real-time environmental data and real-time human body recognition results. The mute amplitude coefficient is then calculated based on the real-time demand judgment result and the current state data of the toilet. When the mute mode is manually triggered, no environmental assessment is required. The second duration is directly obtained based on the human body recognition results, and the mute amplitude coefficient is adjusted accordingly, making it more suitable for the user's actual needs and improving the user experience.

[0071] It is understandable that when automatically entering silent mode, the initial state must be an unoccupied state. At this time, the silent amplitude coefficient can be adjusted according to the current state data of the toilet. For example, if the current state data of the toilet is that the lid is fully open and there is a timed cleaning program, the silent amplitude coefficient is the maximum silent amplitude coefficient. If the current state data of the toilet is that there is no timed cleaning program, the silent amplitude coefficient of the toilet in the fully open, half-open, and closed states is the maximum silent amplitude coefficient.

[0072] Therefore, when a user starts using the toilet, the noise level of the toilet is adjusted according to the noise level coefficient calculated before use. For example, in toilets with automatic lid opening and automatic ring opening functions, the noise level of the automatic lid opening and automatic ring opening functions is adjusted according to the noise level coefficient before use, thereby avoiding sudden loud noises that may cause psychological discomfort to the user and improving the user experience.

[0073] The demand assessment result includes a demand adjustment state and a no-adjustment state. When the environmental data is an illuminance value, if the real-time illuminance value is greater than the preset illuminance threshold and the real-time human body recognition result indicates that someone is present, the demand assessment result is a demand adjustment state. If the real-time illuminance value is less than or equal to the preset illuminance threshold but the real-time human body recognition result indicates that someone is present, the demand assessment result is a no-adjustment state. If the real-time illuminance value is greater than the preset illuminance threshold but the real-time human body recognition result indicates that no one is present, the demand assessment result is a no-adjustment state.

[0074] In this embodiment, a secondary judgment of the user's actual needs is performed based on environmental data and human body recognition results. When the illuminance value is greater than the preset illuminance threshold and the human body recognition result indicates that someone is present, it may be in the early morning or when the user has turned on the lights. In both of these situations, the user's tolerance for sound is relatively high. At this time, the noise level coefficient can be dynamically adjusted according to the user's usage time, so that the noise level coefficient can meet the user's tolerance for sound as much as possible while also ensuring the user's actual cleaning needs. For example, in a home environment, there may be consecutive use of the toilet, which requires high-intensity cleaning for the user's use.

[0075] When the illuminance value is less than or equal to the preset illuminance threshold but the human body recognition result indicates that someone is present, it is more likely that the user is getting up at night or that other family members are still resting. In this case, the requirement judgment result is that no adjustment is needed, and the noise reduction coefficient is not adjusted based on the user's usage time (the third duration here). The goal is to minimize the toilet cleaning noise when the user is not awake or other family members are not awake, thereby improving the user experience. It is understandable that the probability of the toilet being used consecutively when the user is getting up at night or when other family members are still resting is low. Therefore, a longer cleaning time can replace high-intensity cleaning to reduce the cleaning noise of the toilet.

[0076] When the illuminance value is greater than the preset illuminance threshold but the human body recognition result is no one, the demand judgment result is also no need to adjust the state, so as to avoid making a loud cleaning noise when users are resting during the day.

[0077] In other cases, when the demand assessment result indicates that no adjustment is needed, the noise level coefficient is not adjusted based on the third duration, but is still dynamically adjusted based on the current state data of the toilet, thereby automatically adapting the noise level of the toilet to the full-open, half-open, and closed states.

[0078] As a third embodiment of this application, the current state data of the toilet includes the seated state, the open-loop state, the duration of the seated state, and the duration of the open-loop state. Calculating the noise level coefficient based on the current state data of the toilet includes:

[0079] The duration of the seated state is obtained based on the seated state of the toilet, and the duration of the open state is obtained based on the open state of the toilet.

[0080] Calculate the noise level coefficient based on the duration of the seated state; or...

[0081] Calculate the noise level coefficient based on the duration of the open loop state; or,

[0082] Calculate the silence amplitude coefficient based on the second duration; or,

[0083] Calculate the silence amplitude coefficient based on the third duration; or,

[0084] Calculate the silence amplitude coefficient based on the second duration and the duration of the seated state; or,

[0085] Calculate the silence amplitude coefficient based on the second duration and the duration of the open-circle state; or,

[0086] Calculate the silence amplitude coefficient based on the third duration and the duration of the seated state; or,

[0087] The silence amplitude coefficient is calculated based on the duration of the third phase and the duration of the open-loop state.

[0088] The system identifies the user's usage based on the toilet seat's sitting and open positions, and then adjusts the noise level accordingly.

[0089] In some cases, the silence amplitude coefficient is calculated based solely on the duration of the seated state or the duration of the open-circle state. In this case, the duration of the seated state or the duration of the open-circle state is inversely correlated with the silence amplitude coefficient. The longer the duration of the seated state or the duration of the open-circle state, the smaller the silence amplitude coefficient. The inverse correlation coefficient can be obtained from expert experience or from the relationship coefficient between the user's normal usage time and awake time obtained from a questionnaire survey.

[0090] In some cases, when the user is neither seated nor opening the toilet seat, the noise level coefficient is adjusted based on the second or third duration. In this case, the second or third duration is inversely related to the noise level coefficient. The longer the second or third duration, the smaller the noise level coefficient, in order to accommodate the user's use of the toilet to perform some object handling.

[0091] In other cases, a quietness coefficient is calculated jointly based on the duration of the seated state / duration of the open-coil state and the second duration / third duration. In this case, the quietness coefficient is calculated using the duration of the toilet seated state and the second / third duration to further determine the user's alertness. A first relationship between duration and quietness coefficient can be constructed solely based on the duration of the toilet seated state, and a second relationship can be constructed based on the duration of user non-use. The quietness coefficient is then calculated based on the weighted coefficients of the duration of the toilet seated state, the user non-use duration, the first relationship, and the second relationship. The duration of user non-use is the difference between the second / third duration and the duration of the seated state / duration of the open-coil state. Since users may be detected by the toilet even in the bathroom, and there may be instances where users use the toilet for a short period of time but have already gone through washing and other processes, a weighting coefficient is used to consider both the duration of non-use and the duration of use. This incorporates the time when the user is detected by the toilet in the bathroom into the user's awakeness considerations, thereby improving the adaptability of the quietness amplitude coefficient adjustment.

[0092] In this embodiment, the termination time points of the second duration, the third duration, the duration of the seated state, and the duration of the open-loop state are the time points when the toilet receives the command to execute the next action. It is understood that the time for calculating the noise level coefficient and the time for calculating the noise reduction action amplitude based on the noise level coefficient are relatively short. Therefore, when the toilet receives the command to execute the next action, it first triggers the calculation of the noise level coefficient and the noise reduction action amplitude based on the noise level coefficient, and then executes the next action based on the noise reduction action amplitude. The command to execute the next action can be triggered by the user or a timed action command.

[0093] Taking the flushing action as an example, the toilet is in the open loop state. When the flushing command is received, the duration of the open loop state ends. The noise level coefficient is calculated based on the duration of the open loop state and the second duration / third duration. Then, the flushing volume in the silent mode is calculated based on the initial flushing volume and the noise level coefficient. The noise caused by flushing is reduced by reducing the flushing volume.

[0094] In some cases, when the toilet changes from the open position to the seated position, the timer for the duration of the open position is stopped, and the noise level coefficient is calculated based on the duration of the seated position.

[0095] Understandably, in some cases, a user may not be in either the open or seated position when using the toilet. Therefore, in the absence of both open and seated positions, the noise level coefficient is calculated based on the second or third duration. In the presence of an open position, the noise level coefficient is calculated based on the duration of the open position. In the presence of a seated position, the noise level coefficient is calculated based on the duration of the seated position.

[0096] like Figure 2 As shown in Embodiment 4 of this application, calculating the noise level coefficient based on the current state data of the toilet further includes:

[0097] The noise level coefficient is calculated based on the duration of the seated state and the number of times the device is washed.

[0098] Applied to toilets with a flushing function, when a flushing command is received while the user is seated, a noise level coefficient is calculated based on the number of flushes corresponding to the command and the duration of the seated position. Since a higher number of flushes results in a larger total flush volume, the noise level coefficient is further adjusted based on the number of flushes to balance the needs of toilet use and quiet operation.

[0099] In this embodiment, the toilet noise control method further includes:

[0100] In response to the seating signal, deodorization is prohibited.

[0101] Since a washing cycle may be required when the user is seated, and this cycle demands stable water pressure and flow direction, simultaneous operation of the deodorizing fan could create negative pressure, causing water flow deviation or pressure fluctuations in the cleaning nozzles, thus affecting cleaning effectiveness. Similarly, in toilets with a drying function, simultaneous drying and deodorizing may cause deviation in the drying airflow, reducing user comfort. Furthermore, running both washing and deodorizing cycles simultaneously increases operating noise, impacting the user experience. Therefore, when the toilet senses the user's seat, it disables deodorizing to avoid interference from dual-cycle operation. Since the washing cycle reduces the noise level, reducing the noise of the deodorizing fan compensates for the increased operating noise to improve cleaning effectiveness, minimizing noise while ensuring effective cleaning.

[0102] Specifically, the calculation of the noise level coefficient based on the duration of the seated state and the number of washes also includes:

[0103] The starting node of the deodorization prohibition execution is used as the timer start point for the duration of the sitting state, and the ending node of the washing command execution is used as the timer end point for the duration of the sitting state.

[0104] When a washing command is in effect, the end point of the washing command execution is used as the timing endpoint for the duration of the sitting state. From the start of the deodorization prohibition to the end of the washing process, the user is in a state where dirt may be generated, such as when the user defecates or when the washing water is generated during the washing process. Using this as the duration of the sitting state improves the accuracy of the estimation of cleaning intensity requirements, avoids interference from the duration of subsequent drying processes, and avoids unnecessary reduction in the quietness level.

[0105] Before the user uses the toilet, the washing action corresponding to the washing command, the drying action corresponding to the drying command, or the deodorizing action are all adjusted according to the noise level coefficient before use. This avoids the user being uncomfortable with the noise caused by the actions after getting used to a quiet environment, and improves the user's comfort during use.

[0106] It is understandable that the noise level coefficient is inversely correlated with the noise level of the toilet seat. A smaller noise level coefficient corresponds to a larger noise level, and vice versa. This inverse correlation can be linear or non-linear. Figure 3 , Figure 4 , Figure 5 As shown, during the flushing action, the larger the noise level coefficient, the smaller the flush volume, and the smaller the noise level coefficient, the larger the flush volume. The flushing action is either large or small depending on the flush volume.

[0107] It should be noted that in toilets without a deodorization process, the starting point for timing the duration of the sitting state is the node where the sitting signal is generated.

[0108] As a fifth embodiment of this application, calculating the noise level coefficient based on the current state data of the toilet further includes:

[0109] The noise level coefficient is calculated based on the toilet's open / closed state, auxiliary factor status, and usage status after use.

[0110] The cleaning effect of a toilet can be affected by cleaning agents, etc. Therefore, a noise level coefficient is calculated based on the toilet's open / closed state after use, the status of auxiliary factors, and the usage state to further balance cleaning and noise levels. Auxiliary factors are objects that assist the toilet in cleaning, such as cleaning agents and cleaning balls. The auxiliary factor status represents the cleaning enhancement ratio of these objects. When using auxiliary factors, the required flushing force can be slightly reduced, resulting in a slight increase in the noise level coefficient. By incorporating auxiliary cleaning factors into the calculation while ensuring cleaning effectiveness, the toilet's cleaning power is made closer to actual needs, maximizing noise reduction.

[0111] Optionally, a positive correlation is established between the toilet lid-open state and the noise level coefficient; a positive correlation is also established between the auxiliary factor state and the noise level coefficient; and an inverse correlation is established between the usage state and the noise level coefficient. The larger the toilet lid opening, the larger the noise level coefficient. Therefore, when the toilet lid is closed, the noise level adjustment can be made with a smaller noise level coefficient, improving cleaning power while maintaining as little noise as possible. The better the cleaning effect of the toilet cleaner, the larger the noise level coefficient. This allows for a larger noise level adjustment when using the toilet cleaner, maximizing noise reduction while maintaining cleaning effectiveness. The longer the user uses the toilet, the smaller the noise level coefficient, ensuring effective cleaning. The noise level coefficient is calculated by considering the toilet lid-open state, auxiliary factor state, and usage state after use, balancing cleaning effectiveness and noise reduction. It is understandable that the usage status includes the open state and the duration of the open state, the seated state and the duration of the seated state, the washing state (buttock wash, feminine wash, etc.) and the number of times the washing is performed.

[0112] It should be noted that the initial movement amplitude of the toilet is based on preset initial action parameters, such as preset flushing volume and drying power. Adjusting these initial action parameters according to a noise level coefficient reduces noise during operation, improving user comfort. The control signal can originate from a preset control program. For example, in a toilet with an automatic flushing function, the automatic flushing action is executed in response to an automatic flushing signal, based on the toilet's noise level, and the flushing speed is reduced by adjusting the flushing volume. The control signal can also originate from user operation.

[0113] In some toilets with automatic lid opening and closing mechanisms, the opening and closing range of the lid can be adjusted based on the level of quietness. This allows the lid to close automatically and the toilet to flush after the user has finished using the toilet. In this case, the correspondence between the quietness range coefficient and the toilet's movement range is constructed based on the type of movement, and the calculation of the quietness range coefficient is also performed separately for each type of movement. This adapts to different needs under different movements. For example, the quietness range coefficient calculation for the toilet lid opening and closing movement does not include the current lid opening / closing state or the usage state, as the usage state has no effect on the lid opening and closing movement. However, the quietness range coefficient calculation for the toilet flushing movement does include the current lid opening / closing state and the usage state.

[0114] As a sixth embodiment of this application, a toilet noise control device includes:

[0115] The status recognition unit is used to acquire the current status data of the toilet.

[0116] The amplitude calculation unit is used to calculate the silent amplitude coefficient based on the current state data of the toilet, and to obtain the silent action amplitude of the toilet based on the silent amplitude coefficient and the initial action amplitude of the toilet.

[0117] The execution unit is used to perform toilet actions corresponding to the control signal based on the noise reduction amplitude of the toilet.

[0118] In this embodiment, the status recognition unit includes at least a seating sensor for recognizing the seating status.

[0119] In other embodiments, the state recognition unit further includes an environmental sensor for recognizing environmental data, a human body recognition sensor for recognizing a human body, and a seat ring / cover rotation detection device. The seat ring / cover rotation monitoring device is used to acquire the open ring state and the open cover state.

[0120] It should be noted that the toilet noise control device can be installed in toilets with different functions. In order to avoid functional redundancy, the corresponding hardware of the control device can be added or removed according to the modules that the toilet already has. For example, in a toilet with a seat sensor for recognition, the execution unit can be compatible with the control unit that the toilet itself has, and can be connected to the seat sensor that the toilet itself has to obtain seat status information.

[0121] As a seventh embodiment of this application, the toilet includes:

[0122] The toilet body and the toilet noise control device.

[0123] The toilet noise control device determines whether to enter the quiet mode based on environmental data and human body recognition data. After entering the quiet mode, it calculates the noise level coefficient in real time based on the current status data of the toilet, environmental data, and human body recognition data. By recognizing the duration of the user's use of the toilet, it estimates the cleaning force required by the toilet and dynamically adjusts the range of motion of the toilet body in the quiet mode to balance the cleaning needs and the quietness needs of the toilet, thereby improving the user experience.

The scope of this application includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with the shape and structure of this application are within the protection scope of this application.
