Description

Technical Field

[0001] This utility model belongs to the field of smart home technology, specifically, it relates to a multifunctional bedside table. Background Technology

[0002] With the rapid development of the smart home industry, the bedroom, as the core resting space of the family, has placed higher demands on the functional integration and ease of use of furniture. As a key piece of furniture in the bedroom that matches the bed, the bedside table has gradually upgraded its function from the traditional single function of storing items to an integrated storage service, becoming a core carrier to meet users' diverse needs such as keeping drinks warm before bed, charging electronic devices, storing personal items, and storing medicines.

[0003] However, current bedside table products and related patented technologies still have many limitations in practical applications, making it difficult to fully meet users' daily needs: Regarding refrigerated storage, existing bedside tables with refrigeration functions (such as the bedside table with refrigeration function disclosed in patent number CN205321751U) can only achieve basic cooling and temperature reduction functions, and cannot disinfect stored items. For items such as medicines and health products, which have high requirements for the sterility of the storage environment, microbial growth can easily lead to contamination, affecting safety. At the same time, condensation will occur when the air inside the drawer cools down during refrigeration. Existing products lack effective moisture-proof measures. Condensation adheres to the surface of items or the inner wall of the drawer, which can easily lead to problems such as medicines becoming damp and deteriorating, fruits rotting, and beverage packaging becoming moldy, seriously affecting the quality and shelf life of stored items.

[0004] Regarding beverage temperature control, while some bedside tables integrate desktop coaster functions (such as the multi-functional smart bedside table disclosed in patent number CN215015154U), they only support unidirectional temperature control. This means they can either only heat and keep beverages warm, failing to meet users' needs for low-temperature preservation of cold drinks in summer, or only provide simple cooling, making it difficult to adapt to the constant temperature requirements of hot drinks in winter. If users want to simultaneously meet the temperature control needs of both hot and cold drinks, they need to purchase additional heated coasters and cooled cups, which not only increases economic costs but also occupies limited desktop space on the bedside table, leading to a cluttered surface.

[0005] In summary, current bedside table products have significant shortcomings in areas such as sterility and moisture protection during refrigerated storage, bidirectional temperature control for beverages, comprehensive functional integration, and flexibility in adapting to different scenarios. Therefore, developing a bedside table that can solve these problems, achieving integrated refrigeration, disinfection, and moisture protection; bidirectional temperature control for beverages; multifunctional integrated safety; and intelligent scenario-based adaptation, has become a key direction for meeting users' daily needs and promoting the upgrade of smart home furniture.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0020] like Figures 1 to 6As shown, a multifunctional bedside table includes a cabinet body 1 and a support platform 2 fixedly connected to the bottom of the cabinet body 1. A partition 3 is fixedly connected to the inner wall of the cabinet body 1 near the top. The cabinet body 1 has a drawer 4 and a drawer 5 inside. A partition 404 is fixedly connected to the inside of the drawer 4. A cabinet door 402 is fixedly connected to the front of the drawer 4. A fingerprint lock 403 is installed on the front of the cabinet door 402. A refrigerator 503 is fixedly installed inside the drawer 5. A cabinet door 502 is fixedly installed on the front of the drawer 5. A partition 504 is fixedly connected to the inner wall of the refrigerator 503. An ultraviolet lamp 505 is fixedly installed on the top of the partition 504. Slide rails 401 and 501 are fixedly connected to the left and right sides of the inner wall of the cabinet body 1. The left and right sides of the drawers 4 and 5 are slidably connected to slide rails 401 and 501, respectively.

[0021] The semiconductor fingerprint lock features a recognition speed of ≤0.3 seconds, supports the storage of 10 fingerprints, and includes an emergency mechanical keyhole. The 405 UV lamp is a 254nm wavelength UV disinfection lamp that automatically starts disinfection after the drawer is closed, with a default disinfection time of 30 minutes and a sterilization rate of ≥99.9%. It automatically shuts off after disinfection. A photosensitive sensor is installed at the drawer opening / closing point, and the lamp body is covered with a light-shielding plate to prevent UV leakage. The photosensitive sensor is electrically connected to the main control chip. When the drawer is closed, the photosensitive sensor detects a darkness signal, and the main control chip starts the UV lamp for disinfection. When the drawer is opened, the photosensitive sensor detects a light signal and immediately cuts off the UV lamp power to prevent human contact with UV rays.

[0022] Drawer 2 (5) integrates a molecular sieve rotor, a micro fan, and a PTC heater at the rear. The molecular sieve rotor has a diameter of 50mm, a pore size of 0.3nm, and an adsorption capacity of ≥15g / g. The micro fan has a power of 5W and a wind speed of 0.3m / s. The PTC heater also has a power of 50W. The molecular sieve rotor, micro fan, and PTC heater are integrated into the cavity at the rear of drawer 2 (5). A humidity sensor is embedded in the inner wall of drawer 2 (5) and is electrically connected to the main control chip. When the humidity sensor detects that the humidity inside the drawer is >60%RH, the main control chip starts the micro fan to blow humid air over the molecular sieve rotor to adsorb water vapor. Every 4 hours, the PTC heater is activated to heat the rotor to 110℃, causing the adsorbed water vapor to desorb. The fan then exhausts the humid air through the exhaust vent at the back of the cabinet, achieving condensation-free storage.

[0023] A Bluetooth speaker 10 is fixedly installed on the top of partition 3. A speaker outlet 9 is fixedly installed on the right side of the back of cabinet 1. The back of cabinet 1 has a ventilation grille 13, a power interface, and an exhaust vent. Ambient lights 12 are fixedly installed on the left and right sides of the inner wall of cabinet 1 near the top, and ambient lights 11 are fixedly installed on the left and right sides of the inner wall of cabinet 1 near the bottom. The Bluetooth speaker 10 consists of two 5W full-range speakers with a frequency response of 80Hz-20kHz, equipped with a Bluetooth 5.0 chip, supports the A2DP audio protocol, and has a connection distance of ≤10 meters. Volume and track switching can be achieved via buttons. Ambient lights 11 are RGB intelligent lights, supporting color temperature adjustment from 2700K to 6500K and brightness adjustment from 10% to 100%. The upper surface of cabinet 1 features a control panel 6, a wireless fast charging area 7, and a coaster area 8. The coaster area 8 uses a semiconductor cooling chip for rapid cooling and heating. The wireless fast charging area 7 has a diameter of 120mm, a non-slip silicone coating, and a built-in Qi wireless charging coil with a maximum power of 15W, supporting wireless charging for mobile phones and earphones.

[0024] The control panel 6 has a built-in main control chip, which uses an STM32F103RCT6 microcontroller as the core control module. It is electrically connected to the refrigerator drawer, constant temperature coaster, wireless fast charging, fingerprint lock, light, and sound modules, respectively, and receives button or APP commands to provide feedback on the working status.

[0025] The power supply is a 12V / 5A power adapter, with an input of AC100-240V 50 / 60Hz. Power is supplied to each module via wires, and each module branch has an independent fuse to prevent a single module failure from affecting overall operation. The main control chip (STM32F103RCT6) receives two main input signals in real time: manual commands from control panel 6 and detection data from the sensors in each module. After parsing the signals, the chip sends control commands to the corresponding actuators, while simultaneously receiving status feedback from the actuators and dynamically adjusting operating parameters to ensure accurate function implementation.

[0026] The power adapter converts AC 100-240V mains power to DC 12V / 5A DC power, which is then distributed to each functional module via wires. Each module branch has a 2A independent fuse connected in series. When a module experiences a short circuit, overload, or other abnormality, the corresponding fuse blows, cutting off the power supply to that module and preventing the fault from spreading to the entire system, thus ensuring electrical safety.

[0027] Drawer 2.5 incorporates a built-in DS18B20 temperature sensor and an STM32F103 main control chip, offering three preset temperature settings: medicine (2-8℃), fruit (5-10℃), and beverage (12-15℃). These settings can be easily switched using the function buttons on the control panel. The desktop constant-temperature coaster area measures 120mm x 120mm and employs a dual semiconductor cooling chip (TEC1-12705) + aluminum heat-conducting plate structure. It supports bidirectional temperature control, with a heating setting of 55-65℃ and a cooling setting of 5-15℃, achieving a temperature accuracy of ±1℃. The coaster surface features an anti-slip silicone ring to prevent cups from slipping and is covered with high-temperature resistant tempered glass. It includes a TEC1-12705 semiconductor cooling chip, an aluminum heat sink, and a 12V silent fan. The cold end of the cooling chip is in close contact with the inner wall of the refrigerator drawer and is coated with thermal grease to enhance heat conduction. The hot end connects to the aluminum heat sink, and a silent fan is installed on the outside of the heat sink, corresponding to the ventilation grille on the back of the cabinet. After receiving the temperature control button command, the main control chip supplies power to the cooling element, which rapidly cools the cold end, reducing the temperature inside the drawer to the target level. The temperature sensor provides real-time temperature feedback, and if the temperature exceeds the tolerance, the main control chip adjusts the power of the cooling element to maintain a stable temperature.

[0028] When the main control chip receives a refrigeration command, it supplies a directional current to the cooling chip, creating a temperature difference between the two ends of the cooling chip. The cold end adheres tightly to the inner wall of the refrigeration drawer through thermal grease, quickly absorbing heat from the drawer and lowering the internal temperature to the target level. The hot end connects to an aluminum heat sink, and a 12V silent fan exhausts the heat from the heat sink through the ventilation grille 13 on the back of the cabinet. The temperature sensor inside the drawer provides real-time temperature feedback. If the temperature exceeds the target level by ±0.5℃, the chip adjusts the power supply to the cooling chip to maintain a stable temperature.

[0029] Disinfection is achieved using a 254nm low-pressure mercury lamp. A photosensitive sensor is installed at the drawer opening and closing point: when the drawer is closed, the sensor detects a darkness signal and transmits the data to the main control chip. The chip then activates the ultraviolet lamp, which destroys the DNA structure of microorganisms through ultraviolet light, achieving a 99.9% sterilization rate. If the drawer is opened during the disinfection process, the sensor detects a light signal and immediately sends a power-off command, instantly shutting off the ultraviolet lamp to prevent ultraviolet leakage and harm to the human body. After the drawer is closed again, the disinfection program continues for the remaining time.

[0030] To address the issue of condensation caused by air cooling during refrigeration, the system employs an adsorption-desorption-exhaust cycle for moisture prevention: a humidity sensor monitors the humidity inside the drawer in real time. When the humidity exceeds 60%RH, the main control chip activates a micro fan to blow humid air towards a molecular sieve rotor, which captures moisture from the air through physical adsorption. Every 4 hours, the system automatically activates a PTC heater to heat the rotor to 110℃, desorbing the adsorbed moisture into a gaseous state. The micro fan then exhausts the humid air through the exhaust vents on the back of the cabinet. When the humidity is ≤50%RH, the fan and heater are turned off, achieving condensation-free storage inside the drawer.

[0031] When the coaster heating button is pressed, the main control chip supplies a positive current to the dual TEC1-12705 semiconductor cooling chip. The hot end of the cooling chip generates heat, which is transferred to the tempered glass panel of the coaster area through an aluminum heat-conducting plate coated with thermal grease, raising the panel temperature to 55-65℃. The DS18B20 temperature sensor is embedded in the heat-conducting plate to provide real-time feedback on the panel temperature. If the deviation exceeds 1℃, the chip adjusts the power supply current to maintain a stable temperature, thus achieving constant temperature preservation of hot beverages such as coffee and tea.

[0032] When the coaster cooling button is pressed, the main control chip sends a reverse current to the semiconductor cooling chip, which generates cooling at the cold end of the chip. This cooling is then transferred to the panel through the heat-conducting plate, causing the panel temperature to drop to 5-15℃. The temperature sensor continuously monitors the temperature. If the panel temperature is more than 1℃ lower than the set value, the chip reduces the power supply current; if it is more than 1℃ higher than the set value, the power supply current increases, ensuring that cold drinks such as cola and juice are kept at a low temperature for a long time without needing to be frequently put into the refrigerator.

[0033] The wireless fast charging module has a built-in Qi standard wireless charging coil that works on the principle of electromagnetic induction: when a device that supports wireless charging is placed in the fast charging area covered by anti-slip silicone, the coil generates an alternating magnetic field, and the device's built-in coil induces the magnetic field to generate current, thus realizing the transfer of electrical energy; the module can automatically identify the device's charging needs and output adaptive power of 5W / 7.5W / 10W / 15W / 18W; when the device is fully charged or the temperature exceeds 60℃, the module automatically cuts off the power to prevent overcharging and overheating from damaging the device.

[0034] The fingerprint lock module uses the FPC1020 semiconductor fingerprint recognition module, which realizes identity verification by collecting biometric features such as the ridges and valleys of the fingerprint: when a finger presses the module, the module collects the fingerprint image through capacitive sensing and compares it with the pre-stored fingerprint template; when the comparison is successful, the module sends a command to the EM-LS01 electronic lock body, the lock body unlocks, and the drawer can be opened smoothly; if the comparison fails 5 times in a row, the module locks for 30 seconds; if the module malfunctions, the drawer can be opened with a hidden emergency mechanical key to ensure ease of use.

[0035] An RGB LED light strip is installed on the inner front of the cabinet. The main control chip controls the light through PWM technology: pressing the light adjustment button adjusts the current ratio of the RGB three colors to achieve color temperature switching between warm, neutral, and cool light; the brightness + / - buttons adjust the PWM duty cycle to achieve brightness adjustment from 10% to 100%; when sleep mode is selected, the chip controls the PWM duty cycle to gradually decrease, and the light gradually dims and turns off within 3 minutes; when the drawer is opened at night, the photosensitive sensor triggers the light to turn on automatically, and it automatically turns off 10 seconds after the drawer is closed, adapting to the bedroom nighttime use scenario.

[0036] The Bluetooth speaker module is equipped with a CSR8675 Bluetooth 5.0 chip and supports the A2DP audio protocol: mobile phones, tablets and other devices search for and connect to the chip via Bluetooth. After the audio signal is decoded by the chip, it is transmitted to two 5W full-range speakers. The speakers convert the electrical signal into sound waves, which are then propagated through the speaker output port 9 on the right side of the back of the cabinet. The volume + / - buttons on the control panel adjust the amplification of the audio signal, and the previous / next track button sends a command to the Bluetooth chip to switch tracks, meeting the audio playback needs of the bedroom.
