Description

Technical Field

[0001] This invention relates to the field of smart home technology, and specifically provides a control method for a smart home system. Background Technology

[0002] As people's living standards continue to improve, the requirements for home environment in modern families are also increasing. Bathrooms typically contain toilets, showers, and other household facilities. After use, these facilities often produce strong odors due to lack of ventilation. Furthermore, since bathroom drains are usually connected to sewage pipes, backflow of odors is common, further contributing to the strong smell in the bathroom.

[0003] To remove odors from the bathroom, people usually try to ventilate it. Currently, exhaust fans are mainly used for ventilation, but the effect is limited, and bathrooms often still have a strong odor. Furthermore, people usually only turn on the exhaust fan manually after noticing the odor, which is a poor experience. In addition, bathrooms, being a consistently damp environment, are prone to bacterial growth, which can harm people's health.

[0004] Accordingly, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problems of poor odor removal effect and easy growth of bacteria in the bathroom that endanger people's health in the prior art by manually turning on the exhaust fan for ventilation.

[0006] This invention provides a control method for a smart home system, the smart home system including a toilet, an air purifier, and a bathroom heater / ventilation unit. The air purifier is configured to at least deodorize and sterilize the air, and the bathroom heater / ventilation unit is configured to at least exhaust ventilation from the bathroom.

[0007] The control method includes:

[0008] Obtain the duration of a person's stay in the bathroom;

[0009] Obtain the first usage status of the toilet;

[0010] The operation of the air purifier and / or the bathroom heater is controlled based on the duration and the initial usage status of the toilet.

[0011] In the preferred embodiment of the above control method, the step of "controlling the operation of the purifier and / or the bathroom heater according to the duration and the first usage status of the toilet" specifically includes:

[0012] If the duration is less than the first preset duration, the purifier is further selectively controlled to operate based on the first usage status of the toilet.

[0013] If the duration exceeds the second preset duration, the purifier and / or the bathroom heater will be controlled to operate based on the first usage status of the toilet.

[0014] In the preferred embodiment of the above control method, the operating mode of the purifier includes a photocatalytic mode, and the step of "further selectively controlling the operation of the purifier according to the first usage condition of the toilet" specifically includes:

[0015] If the toilet is used, the air purifier is controlled to operate in the photocatalytic mode;

[0016] If the toilet is not in use, the purifier is not controlled to operate.

[0017] In a preferred embodiment of the above control method, the control method further includes:

[0018] After the purifier has been running in the photocatalytic mode for a third preset duration, the purifier is controlled to stop running.

[0019] In the preferred embodiment of the above control method, the operating mode of the purifier further includes a negative ion mode, and the operating mode of the bathroom heater includes an exhaust mode. The step of "further controlling the operation of the purifier and / or the bathroom heater according to the first usage condition of the toilet" specifically includes:

[0020] If the toilet is not in use, control the purifier to run the negative ion mode;

[0021] If the toilet is used, the bathroom heater is controlled to operate in the ventilation mode.

[0022] In a preferred embodiment of the above control method, the control method further includes:

[0023] After controlling the purifier to run the negative ion mode for the fourth preset time, the humidity in the bathroom is obtained;

[0024] The operating mode of the purifier is controlled according to the humidity level.

[0025] In the preferred embodiment of the above control method, the purifier's operating mode further includes a sterilization mode. The step of "controlling the purifier's operating mode according to the humidity" specifically includes:

[0026] If the humidity is greater than the humidity threshold, the purifier is controlled to continue running in the negative ion mode, and the humidity in the bathroom is continuously monitored and the operating mode of the purifier is further controlled based on the humidity.

[0027] If the humidity is less than or equal to the humidity threshold, the purifier will stop running after operating the sterilization mode for the fifth preset time.

[0028] In a preferred embodiment of the above control method, the control method further includes:

[0029] After controlling the bathroom heater to run the sixth preset time of the ventilation mode, the second usage status of the toilet is obtained again;

[0030] The operation of the bathroom heater and / or the air purifier is controlled according to the second usage status of the toilet.

[0031] In the preferred embodiment of the above control method, the operating mode of the purifier further includes a photocatalytic mode. The step of "controlling the operation of the bathroom heater and / or the purifier according to the second usage status of the toilet" specifically includes:

[0032] If the toilet is still in use, the bathroom heater is controlled to continue running the exhaust mode, and the usage status of the toilet is continuously acquired. The operation of the bathroom heater and / or the air purifier is further controlled based on the usage status of the toilet.

[0033] If the toilet is not in use, the air purifier is controlled to operate in the photocatalytic mode.

[0034] In a preferred embodiment of the above control method, the control method further includes:

[0035] After controlling the purifier to operate in the photocatalytic mode for a seventh preset time, control the purifier to stop operating; and / or

[0036] While controlling the air purifier to operate in the photocatalytic mode, or afterward, control the bathroom heater to stop operating.

[0037] In the technical solution of this invention, the smart home system includes a toilet, an air purifier, and a bathroom heater. The air purifier is configured to at least deodorize and sterilize the air, and the bathroom heater is configured to at least ventilate the bathroom. The control method of this invention includes: acquiring the duration of a person's presence in the bathroom and the first usage status of the toilet; and controlling the operation of the air purifier and / or the bathroom heater based on the duration and the first usage status. Through this control method, based on the duration of a person's presence in the bathroom and the specific usage of the toilet, the system automatically performs deodorization, sterilization, or ventilation in the bathroom. This improves the intelligence level of the smart home system, ensuring timely deodorization, sterilization, or ventilation in the bathroom, optimizing air quality, and enhancing the user experience.

[0038] If the time a person spends in the bathroom is less than the first preset time, it means the person's stay is relatively short, perhaps just washing their hands or urinating. The odor generated during this time is not significant. In this case, the purifier's operation is selectively controlled based on the initial usage of the toilet. Specifically, if the toilet is used, some odor will inevitably be produced. In this case, the purifier will operate in photocatalytic mode to deodorize the air in the bathroom, promptly removing odors and ensuring better air quality. If the toilet is not used, it means the user may have only washed their hands, and no odor was generated during the user's bathroom use. In this case, the purifier will not operate. This control method selectively controls the purifier's operation based on the toilet's usage when the person's time in the bathroom is short. The purifier operates when odor removal is needed and shuts off when not needed. This effectively removes odors while minimizing purifier operation, extending the lifespan of the purifier's functional modules, and saving energy.

[0039] If a person spends more than the second preset time in the bathroom, it indicates they have been there for a relatively long period. In this case, the user may be showering or using the toilet. The air purifier and / or bathroom heater will then be adjusted based on the toilet's initial usage status. Specifically, if the toilet is not in use, it suggests the user may be showering, washing clothes, etc. While the odor generated during these activities may not be strong, the likelihood of water use is high, and a damp environment easily breeds bacteria. In this case, the air purifier will operate in negative ion mode, using the generated negative ions to disinfect the bathroom. Simultaneously, negative ions can also sterilize human skin and have health benefits, resulting in better disinfection and an improved user experience. After the air purifier has been running in negative ion mode for a fourth preset time, the humidity in the bathroom is monitored. If the humidity is higher than the threshold, it indicates the user is showering. In this case, the air purifier will continue running in negative ion mode and continuously monitor the humidity, adjusting its operation accordingly to better ensure air quality and enhance the user experience. If the humidity is less than or equal to the humidity threshold, it means that the user is not taking a shower, but may be washing clothes or applying makeup. In this case, the air purifier will be controlled to run the fifth preset time of the sterilization mode and then stop running to sterilize the bathroom.

[0040] If the toilet is in use, the odor is usually quite strong. In this case, the bathroom heater / ventilation mode will be activated to extract the odorous air from the bathroom and remove the odor as quickly as possible. After the bathroom heater / ventilation mode has been activated for the sixth preset time, the toilet's usage status will be monitored again. If the toilet is still in use, the bathroom heater / ventilation mode will continue to be activated to further ventilate the bathroom and remove the odor. The bathroom heater / ventilation mode and / or air purifier will be activated based on the toilet's usage status. If the toilet is not in use, it means the user has finished using the toilet and is washing their hands or performing other actions. Since the toilet was previously used, even after the bathroom heater / ventilation and odor removal, some odor may still remain in the bathroom. In this case, the air purifier will be activated in photocatalytic mode to remove odors from the bathroom air and ensure freshness.

[0041] This control method allows for better control of the air purifier and / or bathroom heater when a person spends a significant amount of time in the bathroom. When the toilet is not in use, the purifier is first set to negative ion mode, and then adjusted to either negative ion mode or sterilization mode based on the bathroom's humidity. When the toilet is in use, the bathroom heater is first set to exhaust mode, and then the toilet's usage status is monitored again. Based on this status, the bathroom heater is either set to continue operating in exhaust mode or the purifier to operate in photocatalytic mode. This allows for better control of the bathroom heater and / or purifier based on the user's actual bathroom conditions, improving the intelligence of the smart home system, achieving better sterilization and odor removal effects, and ensuring better air quality and cleanliness in the bathroom.

[0046] Figure 4 This is a flowchart illustrating a scenario where, according to an embodiment of the present invention, the toilet is not used when the duration of a human being in the bathroom exceeds a second preset duration. Detailed Implementation

[0047] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0048] It should be noted that in the description of this invention, the terms "first," "second," "third," "fourth," "fifth," "sixth," and "seventh" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this application, unless otherwise expressly specified and limited, the terms "connected" or "connected" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0049] Currently, people typically turn on the exhaust fan manually only after noticing an odor, resulting in insufficient and ineffective odor removal. Furthermore, exhaust fans alone are not efficient at eliminating odors. In addition, bacteria can easily grow in bathrooms, posing a health risk. Therefore, this invention controls the operation of the air purifier and / or bathroom heater based on the duration of time spent in the bathroom and the initial use of the toilet. This allows for automatic and timely odor removal, sterilization, or ventilation in the bathroom, improving the intelligence of the smart home system, ensuring effective odor removal and sterilization, and enhancing the user experience.

[0050] In this invention, the smart home system includes a toilet, an air purifier, and a bathroom heater, all operating within the same Internet of Things (IoT) network. Specifically, the smart home system also includes a server, which communicates with the toilet, air purifier, and bathroom heater via WiFi, Bluetooth, LAN, 3G, 4G, 5G, etc. It should be noted that this server can be, but is not limited to, a backend server, a cloud server, etc.

[0051] In this invention, a smart lock can be installed on the bathroom door, and this smart lock communicates with a server. The smart lock includes a timing module that starts timing after the door is closed from the inside of the bathroom, measuring the duration the door remains closed. This duration is the time a person spends inside the bathroom. The smart lock can transmit this duration to the server. Obviously, other methods can also be used to determine the duration a person spends inside the bathroom. For example, a camera can be installed at the bathroom entrance to capture images of the entrance. Image analysis can determine the time the user entered the bathroom, and based on this time, the duration the user spent inside can be determined. Without departing from the principles of this application, those skilled in the art can flexibly choose to determine the duration a person spends inside the bathroom according to the specific application scenario, as long as the air purifier and bathroom heater can be accurately controlled based on this duration and the toilet's usage status.

[0052] In this invention, the toilet includes a toilet seat with a pressure sensor installed on it. This pressure sensor detects the pressure value exerted on the toilet seat, thereby determining whether the toilet is in use. Specifically, if the pressure value exerted on the toilet seat is greater than or equal to a preset pressure value, the toilet is in use; if the pressure value is less than the preset pressure value, the toilet is not in use. Obviously, the toilet itself can determine whether it is in use based on the pressure value detected by the pressure sensor and then transmit this information to a server. Alternatively, the toilet can transmit the pressure value detected by the pressure sensor to the server, and the server then determines whether the toilet is in use.

[0053] It should be noted that infrared detection modules, radar detection modules, and other detection modules can also be installed on the toilet seat to detect whether a person is sitting on the toilet.

[0054] In this invention, the air purifier includes a photocatalytic module, a negative ion module, and a sterilization module. Therefore, the operating modes of the air purifier include a photocatalytic mode, a negative ion mode, and a sterilization mode. When the air purifier is in photocatalytic mode, it can remove odors from the air. When it is in negative ion mode, it can sterilize the air and the human body and also have health benefits. When it is in sterilization mode, it can sterilize the air.

[0055] The photocatalytic module is designed to remove odors from the air when activated. It can be made by using aluminum plates, aluminum mesh, or honeycomb ceramics as a substrate, onto which a photocatalyst such as titanium dioxide is loaded. Odors in the air are typically caused by toxic and harmful gases and volatile organic compounds. As air flows through the photocatalytic module, it decomposes these substances, thus removing odors.

[0056] The negative ion module is designed to ionize the air and generate negative ions when powered on. These negative ions can effectively remove bacteria and viruses from the air. At the same time, negative ions can penetrate deep into the stratum corneum of human skin to sterilize the skin and also have health benefits, providing excellent therapeutic effects for the human body.

[0057] The sterilization module can be an ultraviolet (UV) sterilization module, which is configured to emit UV light when powered on, thus sterilizing the irradiated area. Preferably, the UV sterilization module is a UVC sterilization module.

[0058] In this invention, the operating modes of the bathroom heater include exhaust mode, lighting mode, heating mode, and ventilation mode. When the bathroom heater is in exhaust mode, it can exhaust the air in the bathroom; when it is in lighting mode, it can provide a light source in the bathroom; when it is in heating mode, it can increase the temperature in the bathroom; and when it is in ventilation mode, it can exhaust the air in the bathroom and introduce fresh air.

[0059] In this invention, the purifier is also equipped with a humidity sensor, which can detect the humidity in the bathroom.

[0060] It should be noted that the humidity sensor can be, but is not limited to, resistive humidity sensing elements, capacitive humidity sensing elements, etc.

[0061] It should be noted that the humidity sensor mentioned above does not have to be installed on the air purifier. Instead, it can be installed on the toilet, the bathroom heater, the side of the door inside the bathroom, or other locations within the bathroom, as long as it can accurately detect the humidity in the bathroom.

[0062] In this invention, the smart home system also includes a control module, which is connected to the toilet, air purifier, and bathroom heater respectively. This control module can control the operation of the air purifier and / or bathroom heater based on the duration of human presence in the bathroom and the initial usage status of the toilet. When the duration is less than a first preset duration, it can selectively control the air purifier based on the initial usage status of the toilet; when the duration is greater than a second preset duration, it can control the air purifier to operate in negative ion mode; when the toilet is not in use, it can control the air purifier to operate in negative ion mode; after a fourth preset duration of negative ion mode operation, it can control the air purifier's operating mode based on the humidity in the bathroom; after a sixth preset duration of controlling the bathroom heater to operate in exhaust mode, it can control the air purifier to operate in photocatalytic mode based on the second usage status of the toilet, or continue to control the bathroom heater to operate in exhaust mode, etc.

[0063] It should be noted that this control module can physically be a control chip installed in a toilet, air purifier, or bathroom heater in the bathroom, or it can be a controller specifically used to execute the method of this application, or it can be a functional module or functional unit of a general controller.

[0064] The following reference Figures 1 to 4 This paper describes possible implementations of the control method for the smart home system of the present invention.

[0065] like Figure 1 As shown, in one possible implementation, the control method of the present invention includes:

[0066] S100: Obtain the duration of a person's stay in the bathroom;

[0067] S101: Obtain the initial usage status of the toilet;

[0068] S102: Control the operation of the air purifier and / or bathroom heater based on the duration and the initial usage of the toilet.

[0069] In S100, based on the smart door lock installed on the door, the duration of the user's entry into the bathroom and stay in the bathroom is obtained.

[0070] In step S101, the first usage condition of the toilet is determined based on the pressure value detected by the pressure sensor installed on the toilet.

[0071] In S102, based on the duration obtained in S100 and the first usage status of the toilet obtained in S101, the air purifier and / or bathroom heater are controlled to operate.

[0072] Through the above control methods, the bathroom can be automatically deodorized, sterilized, or ventilated according to specific circumstances. This improves the intelligence of the smart home system, ensures effective deodorization and sterilization, optimizes air quality in the bathroom, and enhances the user experience.

[0073] In one possible implementation, the time a person spends in the toilet is less than a first preset time; for example, if the first preset time is 3 minutes, and the person spends only 2 minutes in the toilet. This indicates that the person's time in the toilet is relatively short, perhaps just washing their hands or urinating, during which the odor generated is not significant. In this case, the purifier's operation is selectively controlled based on the initial usage of the toilet. See below for further details. Figure 2 This invention describes possible implementations of the control method for when the duration of human stay in the bathroom is less than a first preset duration.

[0074] like Figure 2 As shown, in one possible implementation, the control method of the present invention further includes:

[0075] S200: Obtain the initial usage status of the toilet;

[0076] S201: If the toilet is not in use, the air purifier will not be controlled to operate;

[0077] S202: If the toilet is used, control the air purifier to run in photocatalytic mode;

[0078] S203: After the air purifier has been running in photocatalytic mode for the third preset duration, control the air purifier to stop running.

[0079] In S200, similar to S101, the first usage condition of the toilet is determined based on the pressure value detected by the pressure sensor installed on the toilet.

[0080] In S201, if the first usage status of the toilet obtained in S200 is that it is not used, it means that the user may have just washed their hands and no odor was generated during the user's use of the toilet. In this case, the purifier is not controlled to run.

[0081] In S202, if the first usage status of the toilet obtained in S200 is that it has been used, then some odor will be generated more or less. At this time, the purifier is controlled to run the photocatalytic mode to remove odors from the air in the bathroom and remove the odors in the bathroom in time.

[0082] In S203, after controlling the purifier to run in photocatalytic mode for the third preset time in S202, for example, the third preset time is 5 minutes. After controlling the purifier to run in photocatalytic mode for 5 minutes, the odor in the bathroom has been largely removed. At this point, the purifier is controlled to stop running.

[0083] It should be noted that after controlling the air purifier to run in photocatalytic mode for the third preset time in S202, you can choose not to stop the air purifier. Instead, you can control the air purifier to run in negative ion mode or sterilization mode for a period of time after the third preset time of photocatalytic mode, and then control the air purifier to stop. Alternatively, you can control the air purifier to run in photocatalytic mode continuously until the user leaves the bathroom.

[0084] Through the above control method, when the time a person is in the bathroom is relatively short, the purifier is controlled to run when odor removal is needed, and the purifier is controlled not to run when odor removal is not needed. This can remove odors in the bathroom in a timely manner while reducing the operation of the purifier, extending the service life of each functional module in the purifier, and saving energy.

[0085] It should be noted that in S201, the purifier can also be controlled to operate in negative ion mode or sterilization mode when the toilet is not in use. Obviously, it is also possible, in S202, to control the purifier to operate in photocatalytic mode periodically when the toilet is in use. Without departing from the principles of this application, those skilled in the art can flexibly choose the specific operating mode of the purifier according to the specific application scenario, as long as it can improve the intelligence level of the smart home system and ensure the air quality in the bathroom.

[0086] In one possible implementation, the duration of a person's time in the bathroom exceeds a second preset time; for example, if the second preset time is 5 minutes and the duration of the person's time in the bathroom is 8 minutes. This indicates that the person spends a relatively long time in the bathroom. In this case, the user may be showering or using the toilet. Therefore, the air purifier and / or bathroom heater are further controlled based on the initial usage of the toilet. See below for further details. Figure 3 and Figure 4 This invention describes possible implementations of the control method for when a person spends more than a second preset time in the bathroom.

[0087] like Figure 3 As shown, in one possible implementation, the control method of the present invention further includes:

[0088] S300: Obtain the initial usage status of the toilet;

[0089] S301: If the toilet is not in use, control the air purifier to run in negative ion mode;

[0090] S302: After the purifier has been running in negative ion mode for the fourth preset time, obtain the humidity in the bathroom;

[0091] S303: Determine if the humidity is greater than the humidity threshold. If yes, proceed to S305; otherwise, proceed to S304.

[0092] S304: The air purifier will stop running after the fifth preset time in the sterilization mode.

[0093] S305: Controls the air purifier to continue operating in negative ion mode.

[0094] In S300, similar to S101 and S200, the first usage condition of the toilet is determined based on the pressure value detected by the pressure sensor installed on the toilet.

[0095] In step S301, if the toilet's initial usage status, as obtained in step S300, is that the toilet is not in use, it indicates that the user may be showering or washing clothes in the bathroom. This process takes a relatively long time but doesn't produce a strong odor. However, it involves a high probability of water use, and the damp environment easily breeds bacteria. In this case, the air purifier is controlled to operate in negative ion mode, using the negative ions generated by the purifier to disinfect the bathroom. Simultaneously, negative ions can also sterilize human skin and have health benefits, thus achieving a better disinfection effect and improving the user experience.

[0096] In S302, after controlling the purifier to run in negative ion mode for the fourth preset duration in S301, for example, the fourth preset duration is 10 minutes, the humidity in the bathroom is obtained through the humidity sensor on the purifier after the purifier has been running in negative ion mode for 10 minutes.

[0097] It should be noted that after controlling the air purifier to run in negative ion mode in the S301, it is also possible to stop controlling the air purifier's operation mode based on the humidity in the bathroom, instead of controlling the air purifier to run in negative ion mode until the user leaves the bathroom, or to control the air purifier to run in negative ion mode for a period of time and then stop running.

[0098] In S303, based on the humidity obtained in S302, it is determined whether the humidity is greater than the humidity threshold.

[0099] If the humidity exceeds the humidity threshold, for example, if the threshold is 60% and the humidity is 80%, it indicates that the humidity in the bathroom is high, suggesting the user is likely showering. In this case, the purifier will continue operating in negative ion mode, i.e., execute S305. While or after the purifier continues operating in negative ion mode, the humidity sensor will continuously monitor the humidity in the bathroom, i.e., return to execute S302 and further adjust the purifier's operating mode based on the detected humidity, thereby better ensuring air quality in the bathroom and improving the user experience.

[0100] It should be noted that when the S303 detects that the humidity is greater than the humidity threshold, it can also control the purifier to continue running in negative ion mode without detecting the humidity in the bathroom or further controlling the purifier's operating mode based on the humidity.

[0101] If the humidity is less than or equal to the humidity threshold (e.g., 50% humidity, where the threshold is 60%), it indicates that the user has been in the bathroom for an extended period not for showering, but for activities such as washing clothes or applying makeup. In this case, the air purifier will be controlled to run in sterilization mode and will stop operating after the fifth preset duration of sterilization, i.e., executing S304. For example, the fifth preset duration is 10 minutes. By controlling the air purifier to run in sterilization mode for 10 minutes and then stopping, the air purifier can perform sterilization treatment in the bathroom. Stopping operation after sterilization ensures effective sterilization while reducing the operating time of the sterilization module, extending its lifespan, and saving energy.

[0102] Through the above control method, when a person spends a relatively long time in the bathroom, if the toilet is not used, the purifier is first controlled to run in negative ion mode. Then, depending on whether the user is taking a shower, the purifier is controlled to run in negative ion mode or sterilization mode. In this way, the purifier's operating mode can be adjusted according to the user's actual situation, thereby improving the intelligence level of the smart home system, achieving better sterilization effect, ensuring the freshness and cleanliness of the air in the bathroom, and improving the user experience.

[0103] like Figure 4 As shown, in one possible implementation, the control method of the present invention further includes:

[0104] S400: Obtain the initial usage status of the toilet;

[0105] S401: If the toilet is in use, control the bathroom heater to operate in exhaust mode;

[0106] S402: After controlling the bathroom heater to run in the sixth preset time of the ventilation mode, obtain the second usage status of the toilet again;

[0107] S403: If the toilet is still in use, control the bathroom heater to continue running in exhaust mode;

[0108] S404: If the toilet is not in use, control the air purifier to run in photocatalytic mode;

[0109] S405: After controlling the air purifier to run in photocatalytic mode, control the bathroom heater to stop running;

[0110] S406: Control the air purifier to stop running after the seventh preset time of operation in photocatalytic mode.

[0111] In S400, similar to S101, S200, and S300, the first usage condition of the toilet is determined based on the pressure value detected by the pressure sensor installed on the toilet.

[0112] In S401, if the first usage status of the toilet obtained in S400 is that the toilet is in use, the odor generated is usually strong. In this case, the bathroom heater is controlled to run in exhaust mode to extract the odorous air in the bathroom and remove the odor from the bathroom as soon as possible.

[0113] In S402, after controlling the bathroom heater to operate in the ventilation mode for the sixth preset time in S401, for example, the sixth preset time is 5 minutes, the second usage status of the toilet is obtained again through the pressure sensor mentioned above after the bathroom heater has been running for 5 minutes.

[0114] It should be noted that after controlling the bathroom heater to run in the sixth preset time of the ventilation mode, it is not necessary to obtain the second usage status of the toilet again, nor to control the operation of the bathroom heater and / or air purifier based on the second usage status of the toilet.

[0115] In S403, if the second usage status of the toilet obtained in S402 indicates that the toilet is still in use, then the bathroom heater / ventilation unit will continue to operate in exhaust mode to continue ventilating the bathroom and removing odors. Furthermore, while or after controlling the bathroom heater / ventilation unit to continue operating in exhaust mode, the toilet's usage status will continue to be obtained through the aforementioned pressure sensor, meaning that S402 will be executed again, and the operation of the bathroom heater / ventilation unit or air purifier will be further controlled based on the toilet's usage status.

[0116] In S404, if the second usage status of the toilet obtained in S402 is that the toilet is not in use, it means that the user has finished using the toilet and is washing hands or performing other actions. Since the toilet has been used before, even if the bathroom heater has been used to ventilate and remove odors, there will still be some odor remaining in the bathroom. At this time, the air purifier is controlled to run in photocatalytic mode to remove odors from the air in the bathroom and ensure the freshness of the air in the bathroom.

[0117] In S405, after the air purifier is running in photocatalytic mode, the bathroom heater / ventilation unit stops operating. At this point, no additional odors are produced; the existing residual odors are removed simply by running the air purifier in photocatalytic mode.

[0118] It should be noted that you can also stop the bathroom heater while controlling the air purifier to run in photocatalytic mode; that is, execute S405 at the same time as executing S404. Of course, after controlling the air purifier to run in photocatalytic mode, you can also leave the bathroom heater running without stopping it, and instead turn both the air purifier and the bathroom heater on simultaneously.

[0119] In S406, after the air purifier has been running in photocatalytic mode for the seventh preset time in S404, for example, the seventh preset time is 5 minutes, the odor in the bathroom has been basically removed after the air purifier has been running in photocatalytic mode for 5 minutes. At this point, the air purifier is stopped.

[0120] It should be noted that after the S404 controls the air purifier to run in photocatalytic mode for the seventh preset time, it is not necessary to control the air purifier to stop running. Instead, after controlling the air purifier to run in photocatalytic mode for the seventh preset time, it is necessary to control the air purifier to run in negative ion mode or sterilization mode for a period of time, and then control the air purifier to stop running. Alternatively, the air purifier can be controlled to run in photocatalytic mode until the user leaves the bathroom.

[0121] With this control method, if a person spends a long time in the bathroom and the toilet is used, the bathroom heater will first be controlled to run in exhaust mode. Then, depending on the current usage of the toilet, the bathroom heater will continue to run in exhaust mode or the air purifier will run in photocatalytic mode. This allows for better control of the bathroom heater or air purifier based on the actual situation of the user in the bathroom, improving the intelligence of the smart home system, achieving better sterilization and odor removal effects, and better ensuring the air quality and cleanliness in the bathroom.

[0122] It should be noted that in S301, the purifier can be controlled to operate in photocatalytic mode or sterilization mode even when the toilet is not in use. Obviously, it is also possible that in S401, when the toilet is in use, the bathroom heater can be controlled to operate in exhaust mode while the purifier operates in photocatalytic mode. Without departing from the principles of this application, those skilled in the art can flexibly select the specific operating modes of the bathroom heater and purifier according to the specific application scenario, as long as it can improve the intelligence level of the smart home system and ensure the air quality and cleanliness in the bathroom.

[0123] It should be noted that if the duration of a person's stay in the bathroom exceeds the second preset time, the system can control either the air purifier or the bathroom heater based on the initial usage of the toilet.

[0124] It should be noted that the specific values ​​of the humidity threshold, the first preset time, the second preset time, the third preset time, the fourth preset time, the fifth preset time, the sixth preset time, and the seventh preset time are merely illustrative descriptions and are not restrictive. Without departing from the principles of this application, those skilled in the art can flexibly select the specific values ​​of the above-mentioned preset time and humidity threshold according to the specific application scenario, as long as the sterilization and odor removal effects can be ensured.

[0125] In summary, in the preferred embodiment of the present invention, by controlling the operation of the air purifier and / or bathroom heater based on the duration of human presence in the bathroom and the initial usage status of the toilet, timely deodorization, sterilization, or ventilation of the bathroom can be achieved, improving the intelligence level of the smart home system, ensuring effective deodorization and sterilization, and enhancing the user experience. When the duration of human presence in the bathroom is less than a first preset duration, if the toilet is used, the air purifier is controlled to operate in photocatalytic mode; if the toilet is not used, the air purifier is not controlled to operate, thus reducing the air purifier's operation and saving energy while promptly removing odors. When the duration of human presence in the bathroom is greater than the first preset duration, if the toilet is not used, the air purifier is controlled to operate in negative ion mode, and the operation is adjusted according to the humidity level in the bathroom to either negative ion mode or sterilization mode. If the toilet is used, the bathroom heater is controlled to operate in ventilation mode, and the second usage status of the toilet is detected again, controlling the operation of the bathroom heater or air purifier based on this second usage status. This will improve the intelligence level of the smart home system, achieve better sterilization and odor removal effects, and enhance the user experience.

[0126] Although the steps in the above embodiments are described in the above order, those skilled in the art will understand that in order to achieve the effect of this embodiment, different steps do not need to be executed in such order. They can be executed simultaneously (in parallel) or in reverse order. These simple changes are all within the protection scope of this application.

[0127] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.
