Description

Technical Field

[0001] The present invention relates to the technical field of bathroom technology, in particular to an intelligent bathroom cleaning and maintenance system and method thereof. Background Art

[0002] With the continuous improvement of living standards and the rapid development of science and technology, smart home technology is playing an increasingly important role in people's daily lives. Among them, smart bathroom systems, as a key component of smart homes, have received widespread attention in recent years. However, existing smart bathroom cleaning and maintenance systems still have many shortcomings and cannot meet the growing needs of users.

[0003] Currently, smart bathroom cleaning and maintenance systems on the market primarily focus on automated flushing, temperature control, and simple cleaning functions. These systems often employ fixed cleaning routines and lack intelligent adjustments for varying usage scenarios. For example, some systems automatically clean at preset times but lack the flexibility to adjust cleaning frequency and intensity based on actual usage. This fixed model not only leads to unnecessary waste of resources but also makes it difficult to respond to unexpected cleaning needs.

[0004] On the other hand, existing systems also have significant shortcomings in water management. Most systems only provide simple timed water supply or fixed flow control, and are unable to dynamically adjust water consumption based on actual usage needs. This not only wastes water resources but also affects the user experience. For example, if multiple people are using the system continuously, the system may not be able to adjust the water supply in a timely manner, resulting in problems such as insufficient water pressure or unstable temperature.

[0005] Furthermore, existing smart bathroom systems are somewhat lacking in terms of human-computer interaction. Most systems offer only basic button operations or simple touchscreen controls, lacking more intuitive and convenient interaction methods. These operating methods may be difficult for the elderly or those with limited mobility.

[0006] Existing systems also face challenges in terms of cleaning effectiveness. Most systems utilize fixed cleaning devices with limited cleaning range, making it difficult to fully cover every corner of the bathroom space. Furthermore, cleaning intensity is often preset and cannot be intelligently adjusted to suit the type and severity of stains. This can result in poor cleaning results or surface damage from over-cleaning.

[0007] Energy management is another issue of concern. Existing smart bathroom systems often lack effective energy-saving mechanisms, and may continue to consume high power even when not in use. This not only increases users' energy costs but also runs counter to growing environmental awareness.

[0008] Finally, existing systems also have shortcomings in remote management and maintenance. Most systems lack remote monitoring and diagnostic capabilities, and if a failure occurs, they often require on-site inspection and repair by professionals, which not only increases maintenance costs but also may affect normal user experience.

[0009] Given these challenges, there is an urgent need for a smart bathroom cleaning and maintenance system that can intelligently sense usage status, dynamically adjust cleaning strategies, precisely control water usage, provide convenient human-computer interaction, achieve comprehensive cleaning, be highly efficient and energy-efficient, and support remote management. Such a system should be adaptable to the personalized needs of different users, providing a more comfortable, hygienic, and energy-efficient bathroom experience while also reducing maintenance costs and improving system reliability and sustainability.

DETAILED DESCRIPTION

[0028] Please refer to the attached Figure 1-6 The present invention provides an intelligent bathroom cleaning and maintenance system, which includes multiple functional modules and can realize intelligent bathroom cleaning and maintenance.

[0029] The intelligent bathroom cleaning and maintenance system of the present invention includes a detection module 1, a control module 2, a water supply module 3, a cleaning module 4, a drainage module 5, a display module 6, and a voice interaction module 7. These modules work together to realize the intelligent functions of the system.

[0030] The detection module 1 is an important component of the system. It obtains real-time data on the bathroom environment through a variety of sensors. Specifically, the detection module 1 includes an infrared sensor 11, a weight detection device 12, and a volume measurement device 13. The infrared sensor 11 is installed in an appropriate position to detect the presence of a human body and send a corresponding signal. Preferably, the detection range of the infrared sensor 11 covers the entire bathroom area to ensure that the state of a human body entering and leaving can be accurately captured. The weight detection device 12 is installed at the bottom of the bathtub to measure the current total weight of the human body. In one embodiment of the present invention, the measurement accuracy of the weight detection device 12 can reach ±0.1kg to ensure the accuracy of the data. The volume measurement device 13 is used to detect the inner cavity volume of the bathtub, and its measurement accuracy is preferably ±0.1L.

[0031] Control Module 2 is the core of the system, responsible for processing data from Detection Module 1 and making appropriate decisions. Control Module 2 and Detection Module 1 are connected via a high-speed data bus, ensuring real-time and reliable data transmission. Control Module 2 first receives the detection signal, weight data, and volume data from Detection Module 1. Based on this data, Control Module 2 determines whether the system should enter bathing mode or cleaning mode. The specific process of this determination is as follows: 1. If the infrared sensor 11 detects the presence of a human body and the weight measured by the weight detection device 12 is greater than a preset threshold (for example, 30 kg), the system enters the bathing mode.

[0032] 2. If the infrared sensor 11 does not detect a human body, or the weight measured by the weight detection device 12 is less than a preset threshold, the system enters the cleaning mode.

[0033] After determining the mode, the control module 2 calculates the amount of cleaning liquid and bathing liquid, and performs weighted processing to obtain the final mixed liquid amount. The calculation process can be expressed as the following formula: , in, is the amount of mixed liquid, For cleaning liquid volume, For the amount of bath liquid, and is the weight coefficient. Preferably, and The value range of is 0 to 1, and In practical applications, these weight coefficients can be adjusted according to specific needs. For example, in summer, value to increase the amount of water used for bathing, and in winter you can increase value to enhance the cleaning effect.

[0034] The water supply module 3 works closely with the control module 2, controlling the water supply based on the amount of mixed liquid calculated by the control module 2. The water supply module 3 includes a water inlet channel 31 and a solenoid valve 32. The solenoid valve 32, mounted on the water inlet channel 31, precisely controls the flow of water. This invention utilizes advanced solenoid valve control technology, achieving millisecond-level response speeds and ensuring accurate water supply.

[0035] Preferably, the switching frequency of the solenoid valve 32 can be dynamically adjusted according to the amount of mixed liquid. For example, when the amount of mixed liquid is large (e.g., greater than 10L), the solenoid valve 32 can remain open for a long time; when the amount of mixed liquid is small (e.g., less than 5L), the solenoid valve 32 can adopt a pulse switching mode to achieve more precise flow control.

[0036] Cleaning module 4 is responsible for performing the actual cleaning operation. It maintains communication with control module 2 and water supply module 3 to receive cleaning instructions and control water use. Cleaning module 4 includes a spray device 41, a scrubber device 42, and a blower device 43. These three devices work together to achieve a comprehensive and efficient cleaning effect.

[0037] Drainage module 5 is responsible for controlling the system's drainage process. It adjusts the drainage rate based on instructions from control module 2 to ensure water efficiency throughout the cleaning process. In one embodiment of the present invention, drainage module 5 utilizes variable-frequency pump technology, allowing it to adjust the drainage speed based on actual needs, ensuring rapid drainage while minimizing the risk of pipe blockage.

[0038] Display module 6 provides an intuitive interactive interface for users. It displays real-time information such as the system's operating status and cleaning parameters, allowing users to clearly understand the system's performance. Preferably, display module 6 utilizes a high-definition touchscreen with a resolution of at least 1920x1080 to ensure clear display and smooth operation.

[0039] The voice interaction module 7 adds intelligent human-computer interaction to the system. It receives user voice commands, performs semantic analysis using advanced natural language processing algorithms, and then sends the parsed commands to the control module 2 for execution. This greatly improves the system's usability, and voice control is undoubtedly an important aid, especially for users with limited mobility.

[0040] The control module 2 further includes a parameter setting unit 21, a mode determination unit 22 and a liquid volume calculation unit 23. The introduction of these units further enhances the intelligence and flexibility of the system.

[0041] The parameter setting unit 21 is used to receive a reference weight input by the user. This reference weight is typically the average weight of an adult. In a preferred embodiment of the present invention, the reference weight can be set to 65 kg. Of course, the user can adjust this based on actual circumstances. For example, if the system is primarily used by children, the reference weight can be set lower, such as 40 kg.

[0042] The mode judgment unit 22 is responsible for calculating the difference between the current total weight of the human body and the reference weight, and based on this difference, determines which working mode the system should enter. The specific judgment process can be expressed as follows: , in, is the weight difference, is the currently detected weight, is the reference weight. If , the system enters bathing mode; if , the system enters the cleaning mode. This judgment method based on weight difference can well adapt to the needs of users of different body shapes and improve the applicability of the system. The liquid volume calculation unit 23 is responsible for calculating the specific amount of cleaning liquid and bathing liquid, and performing weighted processing to obtain the final mixed liquid volume. The calculation process can be expressed as: , , , in, For cleaning liquid volume, For the amount of bath liquid, is the reference volume (corresponding to the reference weight), is the currently detected volume, and is the weight coefficient.

[0043] This calculation method takes into account both cleaning and bathing needs, and can dynamically adjust water consumption according to actual conditions, ensuring the cleaning effect while avoiding unnecessary waste of water resources.

[0044] The water supply module 3 also includes a humidity detection unit 33 and a water supply control unit 34, which further improves the intelligence level and water use efficiency of the system.

[0045] Humidity detection unit 33 is used to detect the current humidity of the showerhead. In one embodiment of the present invention, humidity detection unit 33 uses a high-precision capacitive humidity sensor with a measurement range of 0-100% RH and an accuracy of ±2% RH. This sensor can quickly respond to changes in ambient humidity and provide accurate humidity data to the system.

[0046] The water supply control unit 34 accurately controls the water supply process based on the mixed liquid volume and humidity data. Specifically, the workflow of the water supply control unit 34 is as follows: 1. When the mixed liquid volume is greater than 0, the solenoid valve 32 is opened at a preset waiting interval. This preset waiting interval can be adjusted according to actual needs, for example, it can be set to 5 minutes. This can avoid the waste caused by continuous water supply.

[0047] 2. When preparing to supply water, first check whether the current humidity is greater than or equal to the preset humidity threshold. This preset humidity threshold can be set to 80% RH. If the current humidity reaches or exceeds this threshold, the water supply is confirmed; otherwise, the water supply is temporarily suspended.

[0048] 3. If the mixed liquid volume is equal to 0 or the current humidity is less than the preset humidity threshold, the solenoid valve 32 is closed and the water supply is suspended.

[0049] This intelligent water supply control method, based on humidity and liquid volume, effectively avoids unnecessary water supply and significantly improves the system's water efficiency. At the same time, regular inspections and water supply ensure that the bathroom environment always maintains appropriate humidity, contributing to good hygiene.

[0050] In summary, the intelligent bathroom cleaning and maintenance system of the present invention achieves highly intelligent and personalized bathroom cleaning and maintenance through the collaborative operation of multiple functional modules. The system not only automatically adjusts operating modes and water consumption based on actual usage but also takes into account environmental factors such as humidity, ensuring cleaning effectiveness while maximizing water conservation. Furthermore, the system provides an intuitive display interface and convenient voice control, significantly enhancing the user experience. These features give the present invention broad application prospects in the smart home sector.

[0051] The intelligent bathroom cleaning and maintenance system of the present invention is not only highly intelligent in its control and water supply, but also features unique innovations in the design of its cleaning module. The cleaning module 4 comprises a telescopic device 44, a cleaning device 45, and a transmission device 46. These three components work together to achieve comprehensive and efficient cleaning.

[0052] The telescopic mechanism 44 is the core component of the cleaning module 4 and comprises a multi-stage telescopic tube 441 and multiple drive motors 442. The multi-stage telescopic tube 441 is constructed of lightweight, high-strength carbon fiber, ensuring both strength and weight. In a preferred embodiment of the present invention, the tube 441 can be extended to a maximum length of 1.5 meters, sufficient to cover a conventional bathtub or shower. The drive motors 442 utilize precision stepper motors with control accuracy of up to 0.1 degrees, ensuring the precise movement of the telescopic mechanism 44.

[0053] Cleaning device 45 integrates three cleaning tools: a spray nozzle 451, a brush head 452, and a blower pipe 453. The spray nozzle 451 features a multi-hole design, spraying water in a fan-shaped pattern, covering a large area and achieving effective cleaning results. The brush head 452 is made of soft and flexible nylon material, effectively removing stubborn stains without damaging the surface. The blower pipe 453 is equipped with a high-speed centrifugal fan, capable of reaching wind speeds of up to 20m / s, which can quickly dry out surface moisture.

[0054] Transmission 46 drives cleaning device 45 along the slide rails, expanding the cleaning range. The slide rails are made of corrosion-resistant stainless steel with a specially treated surface for low friction and smooth, silent operation. Transmission 46 utilizes a rack and pinion mechanism, offering high transmission efficiency and positioning accuracy.

[0055] This multifunctional and highly flexible cleaning module design enables the system of the present invention to adapt to various complex cleaning needs, and whether it is a bathtub, shower room or other bathroom equipment, it can be cleaned comprehensively and deeply.

[0056] Furthermore, the system of the present invention also includes a human counting module 8. Human counting module 8 is in communication with control module 2 and is configured to detect and output the number of people near the bathtub. In one embodiment of the present invention, human counting module 8 utilizes advanced 3D depth camera technology to accurately identify and count the number of people in a space without infringing on user privacy.

[0057] Control module 2 adjusts the water supply rate based on data provided by body counting module 8. Specifically, when the number of detected people is less than or equal to a preset threshold, the system supplies water at the normal rate. This threshold can be set based on actual conditions, for example, to two people. When the number of people exceeds the threshold, the system appropriately reduces the water supply rate to avoid wasting water resources.

[0058] Preferably, the water supply rate can be adjusted using the following formula: , in, is the adjusted water supply rate, is the normal water supply rate, is the adjustment coefficient ( is the number of human bodies detected, is the preset threshold. For example, you can set For every additional person detected, the water supply rate is reduced by 10%. This approach dynamically adjusts the water supply rate based on the actual number of users, ensuring efficient resource utilization and allocation while optimizing the user experience. This strategy is particularly suitable for public places or facilities to cope with fluctuations in user volume over time.

[0059] This intelligent water supply regulation method based on the number of human bodies can not only meet the needs of multiple people using it at the same time, but also effectively avoid waste of resources, reflecting the intelligent and humanized design of the system of the present invention.

[0060] The system of the present invention also includes an energy management module 9. This module is in communication with the control module 2 and is responsible for monitoring the system's power usage and, when appropriate, directing the system into energy-saving mode. In a preferred embodiment of the present invention, the energy management module 9 utilizes an intelligent power monitoring chip capable of real-time monitoring of power usage across the system with an accuracy of up to 0.1W.

[0061] When energy management module 9 detects that the system is inactive (for example, if no human activity is detected for 30 consecutive minutes), it instructs control module 2 to switch the system to energy-saving mode. In energy-saving mode, the system reduces standby power consumption by, for example, turning off the backlight of display module 6 and lowering the sampling frequency of sensors. These measures can reduce the system's standby power consumption to below 5W, significantly saving energy.

[0062] Energy management module 9 also manages the system's integrated battery 91. Battery 91 utilizes a high-capacity lithium-ion battery with a rated capacity of 10,000 mAh, providing up to 24 hours of backup power for the system. Energy management module 9 intelligently controls the charging and discharging of battery 91 based on grid power availability and system power requirements, ensuring continuous system operation while avoiding energy waste.

[0063] The voice interaction module 7 of the present invention includes a voice recognition unit 71, a semantic analysis unit 72 and an instruction execution unit 73. The coordinated operation of these three units enables the system to accurately understand and execute the user's voice instructions.

[0064] The voice recognition unit 71 uses advanced deep learning algorithms to accurately recognize user speech in noisy environments and convert it into text. The unit supports multiple languages and has a recognition accuracy rate of over 98% under ideal conditions.

[0065] The semantic analysis unit 72 is responsible for performing in-depth semantic analysis on the converted text. It utilizes a natural language processing model based on BERT (Bidirectional Encoder Representations from Transformers), enabling it to accurately understand the meaning of user commands, including complex context-sensitive commands. For example, when a user says "heat the water a little higher," the system correctly understands and executes this relative command based on the current state.

[0066] The instruction execution unit 73 converts the results of the semantic analysis into control instructions that can be executed by the system and sends them to the control module 2. This process uses a combination of rule-based and machine learning methods to ensure a fast response to common instructions while being able to adapt to new and uncommon instructions.

[0067] Through this advanced voice interaction system, users can easily control various functions by voice, such as adjusting water temperature, switching cleaning modes, and querying system status. This greatly improves the system's usability, especially for the elderly or users with limited mobility, as voice control provides a more convenient and user-friendly interaction method.

[0068] In summary, the intelligent bathroom cleaning and maintenance system of this invention provides a comprehensive, intelligent, and energy-efficient bathroom solution through advanced cleaning module design, intelligent body counting and water supply regulation, efficient energy management, and convenient voice interaction. These innovations not only improve cleaning efficiency and user experience but also significantly contribute to water and energy conservation, fully demonstrating the latest technological achievements in the smart home field.

[0069] The intelligent bathroom cleaning and maintenance system of the present invention not only realizes highly intelligent control and management locally, but also realizes connection with the outside world through the remote communication module. The system of the present invention also includes a remote communication module 10, which maintains a close communication connection with the control module 2.

[0070] The primary function of the remote communication module 10 is to encrypt and transmit system operating data to a remote server, while also receiving control commands from the remote server. In a preferred embodiment of the present invention, the remote communication module 10 utilizes 4G LTE communication technology, ensuring high-speed and stable data transmission. To further enhance system security, the data transmission process utilizes the AES-256 encryption algorithm, effectively preventing data leakage and unauthorized access.

[0071] The frequency of uploading system operating data can be adjusted based on actual needs. Under normal circumstances, the system uploads operating status data once an hour. When an abnormal situation is detected (for example, a sudden increase in water temperature or a sudden drop in water pressure), the system immediately uploads the relevant data for timely remote diagnosis and resolution.

[0072] Control module 2 adjusts system operating parameters based on received remote control commands. These parameters may include water temperature settings, cleaning mode selection, energy management strategies, etc. Preferably, the execution of remote control commands requires local user confirmation to prevent unauthorized operations from affecting normal user use.

[0073] This remote communication capability greatly enhances the system's maintainability and upgradeability. For example, the system can be updated remotely to include new cleaning algorithms or speech recognition models, eliminating the need for complex manual operations. Remote monitoring also enables timely identification and resolution of potential issues, significantly improving system reliability.

[0074] Furthermore, the display module 6 of the present invention utilizes a touchscreen display design, which not only displays system status but also provides an intuitive user interface. In one embodiment of the present invention, the display module 6 utilizes a 7-inch high-definition IPS screen with a resolution of 1920x1080 and a color saturation of 100% sRGB, ensuring display clarity and color reproduction.

[0075] A key function of the display module 6 is to display the system settings interface, allowing users to adjust system parameters via touch. This interface features a flat design style, a clear layout, and intuitive operation. Users can easily adjust parameters such as water temperature, water pressure, and cleaning mode, and the system will respond and display the results of the adjustments in real time.

[0076] Another key feature is the display of cleaning history and water usage statistics. The system automatically records the duration, water usage, and energy consumption of each cleaning session and displays them visually in charts. This data can help users understand their water usage habits and promote water and energy conservation. The system also provides personalized water-saving recommendations based on this data.

[0077] In addition, the display module 6 also displays system warnings. When an abnormal condition is detected, such as excessive water temperature, abnormal water pressure, or insufficient detergent, the system prominently displays a warning message on the display screen and provides appropriate action suggestions. This timely warning mechanism significantly improves system safety and reliability.

[0078] Finally, the system of the present invention also includes an automatic temperature control module 11, which further improves the system's intelligence level and user experience. The automatic temperature control module 11 maintains a close communication connection with the control module 2 and is responsible for regulating the water temperature and the indoor temperature.

[0079] The core of the automatic temperature control module 11 is the infrared light analyzer 111, which accurately captures the user's body temperature. In a preferred embodiment of the present invention, the infrared light analyzer 111 utilizes a high-precision thermopile sensor with a temperature measurement range of 20°C to 50°C and an accuracy of ±0.1°C. This non-contact temperature measurement method is both accurate and hygienic, making it particularly suitable for bathroom applications.

[0080] Integrating real-time ambient temperature data, the automatic temperature control module 11 intelligently adjusts the water and room temperatures. For example, if it detects a high body temperature (e.g., after exercise), the system automatically lowers the water temperature to provide a more comfortable bathing experience. The water temperature is regulated using a PID (Proportional-Integral-Derivative) control algorithm, enabling fast, smooth, and precise temperature regulation, keeping temperature fluctuations within ±0.5°C.

[0081] Indoor temperature regulation utilizes a fuzzy control algorithm, taking into account multiple factors such as outdoor temperature, humidity, and user preferences. This algorithm maximizes energy savings while ensuring comfort. The system also learns the user's temperature preferences and gradually optimizes the temperature control strategy.

[0082] The automatic temperature control module 11 also features an energy-saving and heat-preservation function. When the system detects the user's absence, it enters an energy-saving and heat-preservation mode. In this mode, the system maintains the water and room temperatures at a low enough level to prevent freezing in pipes (for example, around 10°C). This strategy avoids energy waste and quickly restores the room to a suitable temperature upon the user's return.

[0083] In summary, the intelligent bathroom cleaning and maintenance system of the present invention achieves comprehensive intelligent management through remote communication capabilities, an intelligent display interface, and an automatic temperature control system. The system not only adapts to the personalized needs of different users but also enables remote monitoring and upgrades, significantly improving the user experience and system reliability. Furthermore, the system makes significant contributions to energy conservation and environmental protection, fully reflecting the development trend of modern smart homes. These innovative designs give the present invention significant technical advantages and broad application prospects in the field of intelligent bathrooms.

[0084] It should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the principles of the present invention should be included in the scope of protection of the present invention.
