[0016] 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.

[0017] like Figures 1 to 4 As shown, a height-adjustable furniture table with refrigeration function includes a table body 1 and a support frame 2 fixedly connected to the bottom of the table body 1. A shrink box 301 is fixedly connected to the back of the support frame 2, and a storage box 3 is installed inside the shrink box 301.

[0018] The support frame 2 is internally connected to refrigerator 106 and refrigerator 2 slidably via guide rails. A refrigeration assembly is also fixedly installed inside the support frame 2. This refrigeration assembly includes a compressor, condenser, evaporator, and expansion valve. The heat dissipation end of the evaporator extends into the interior walls of refrigerator 106 and refrigerator 2 107. The compressor, condenser, and expansion valve are connected in series via copper pipes to form a refrigeration cycle loop. This refrigeration assembly is existing technology. Storage cabinet 1 307 and storage cabinet 2 308 are provided on the top left and right sides of the front of storage box 3. Layered cabinet 313 is provided in the middle of the top of the front of storage box 3. The bottom of the inner wall of storage cabinet 1 307 and storage cabinet 2 308 is fixedly connected to a rotating shaft. A rotating frame 312 is rotatably connected to the outer surface of the rotating shaft. Storage cabinet 1 310 and storage cabinet 2 311 are provided on the bottom left and right sides of the front of storage box 3.

[0019] The front of storage box 3 is hinged to a glass panel for shielding refrigerator 106 and refrigerator 2 107. The front of shelf 313 is hinged to a makeup mirror 306, and an LED light is installed on the front of the makeup mirror 306. The LED light on the makeup mirror 306 is powered by a power module. When the makeup mirror 306 is opened, the mirror triggers a built-in contact switch, the circuit is connected, and the LED light illuminates; when the makeup mirror is closed, the contact switch is disconnected, and the LED light turns off, realizing automatic lighting control.

[0020] Storage cabinet 1 (310) and storage cabinet 2 (311) are slidably connected to the inner wall of storage box 3 via guide rails. An electrical box 309 is fixedly installed at the bottom center of the front of storage box 3, and a socket is provided on the front of electrical box 309.

[0021] A mounting groove is provided in the center of the upper surface of the table body 1, and tempered glass 101 is fixedly installed inside the mounting groove. Wireless charging areas 103 and electric buttons 102 are respectively located on the left and right sides of the upper surface of the table body 1. Drawer 1 104 and drawer 2 105 are slidably connected inside the table body 1 via guide rails. Drawer 1 104 and drawer 2 105 have compartmentalized storage areas inside. The wireless charging area 103 has a built-in wireless charging module, which includes a transmitting coil. When a device that supports wireless charging, such as a mobile phone, is placed in the charging area, the transmitting coil is energized and generates an alternating magnetic field. The receiving coil inside the device senses the magnetic field and generates an induced current. After processing by the device's internal rectification and voltage regulation circuits, the current charges the device's battery.

[0022] A slide rail 302 is fixedly connected to the inner wall of the shrink box 301. A slider 303 is slidably connected to the surface of the slide rail 302. A lead screw nut 304 is hung on the back of the slider 303. A motor is fixedly installed at the bottom of the inner wall of the shrink box 301. A lead screw 305 is connected to the output shaft of the motor. The lead screw 305 is threadedly connected to the lead screw nut 304. The top of the lead screw nut 304 is fixedly connected to the bottom of the storage box 3.

[0023] The refrigerant used in the refrigeration components is R600a isobutane, which is environmentally friendly and has refrigeration efficiency suitable for small and medium-sized refrigerators; for a single furniture table, the refrigerant filling amount is 50-80g.

[0024] A temperature sensor is installed inside the support frame 2, with the sensor probe extending into the interior of refrigerator 106 and refrigerator 2 107 to monitor the temperature inside the refrigerator in real time. The temperature data is transmitted to the control chip built into the electric button 102. When the temperature inside the refrigerator is higher than the set value, the control chip automatically starts the compressor and shuts it off when it is lower than the set value, thus achieving constant temperature control. At the same time, a small display screen is added next to the electric button 102 to display the temperature inside the refrigerator in real time.

[0025] Heat dissipation holes are made at the position of the condenser in the support frame 2, and heat dissipation fins are attached to the surface of the condenser to increase the heat dissipation area. A small silent fan is installed inside the support frame 2. The fan starts in conjunction with the compressor to accelerate the air circulation around the condenser and ensure that the refrigeration components can still work stably when the ambient temperature is below 35℃.

[0026] The motor inside the shrink box 301 is a DC geared motor with a rated voltage of 220V, a rated power of 60-100W, and a reduction ratio of 1:50. The motor housing adopts an IP44-level waterproof and dustproof design to prevent moisture or dust that may exist inside the support frame 2 from affecting the motor's lifespan. The motor also has a built-in overheat protection device that automatically cuts off power when it operates continuously for more than 10 minutes or when the temperature exceeds 120℃. It can be restarted after cooling down.

[0027] The lifting stroke of storage box 3 is set to 0-50cm. At the lowest position, storage box 3 is completely retracted into the retractable box 301. At the highest position, the distance between the top of storage box 3 and the bottom of table 1 is ≥10cm to avoid interference with the table. Mechanical limit blocks are installed at the upper and lower ends of slide rail 302, and photoelectric sensors are installed at the corresponding positions of lead screw 305. The double limit prevents the storage box 3 from exceeding the lifting stroke and causing damage to the components. When storage box 3 reaches the limit position, the sensor triggers a signal to control the motor to stop running.

[0028] The main power input terminal of the furniture table is equipped with a leakage protection switch with a rated leakage current ≤30mA and an action time ≤0.1s to prevent electric shock accidents; the wireless charging area 103 has an output power ≤15W, complies with the Qi wireless charging standard, and has built-in overcurrent, overvoltage, and overtemperature protection modules, which automatically stop charging when the device is abnormally charging or the temperature exceeds 60℃; the socket inside the electrical box 309 is a five-hole socket with a rated current of 10A and a built-in child safety door to prevent accidental contact.

[0029] Table 1 is made of solid wood particleboard or cold-rolled steel plate, with a moisture-proof and wear-resistant surface treatment to ensure load-bearing capacity; the edges of the cabinet openings of refrigerator 106 and refrigerator 2107 are rounded with a radius of ≥5mm to avoid bumps and injuries; the glass plate is made of tempered glass with a compressive strength of ≥90MPa, and breaks into small, blunt-angled particles to reduce the risk of injury.

[0030] Wiring holes are pre-set inside the support frame 2 and the table body 1. The power cord uses RVV type copper core PVC insulated sheathed cable. When wiring, maintain a distance of ≥5mm from metal parts to avoid wear and leakage. All electrical component terminals are marked with voltage, polarity and corresponding function for easy installation and maintenance.

[0031] Pre-use assembly and debugging: In the pre-set installation area inside the support frame 2, the compressor, condenser, and expansion valve are fixed by brackets. The heat dissipation end of the evaporator is embedded in the cabinet wall interlayer of refrigerator 106 and refrigerator 207. Then, the compressor, condenser, expansion valve, and evaporator are connected in series by copper pipes to form a closed refrigeration cycle loop. Subsequently, refrigerator 106 and refrigerator 207 are slidably connected to the inner wall of the support frame 2 through guide rails to ensure smooth pushing and pulling of the cabinets.

[0032] Fix the slide rail 302 to the inner wall of the shrink box 301, insert the slider 303 into the slide rail 302 and slide it for testing; hang and fix the lead screw nut 304 to the back of the slider 303, install the motor at the bottom of the inner wall of the shrink box 301, connect one end of the lead screw 305 to the motor output shaft, and thread the other end to the lead screw nut 304; finally, fix the bottom of the storage box 3 to the top of the lead screw nut 304 to complete the assembly of the storage box 3 and the shrink box 301, and fix the shrink box 301 to the back of the support frame 2.

[0033] Tempered glass 101 is embedded in a groove on the upper surface of table body 1. Wireless charging modules corresponding to wireless charging areas 103 and electric control buttons corresponding to electric buttons 102 are installed on the left and right sides of the upper surface of table body 1, respectively. Drawer 1 104 and drawer 2 105 are slidably connected to the inside of table body 1 via guide rails, and partitions are installed in the drawers to form partitioned storage areas. A glass plate and a makeup mirror 306 are installed on the front of storage box 3 via hinges. An LED light is embedded on the front of the makeup mirror 306. An electrical box 309 is fixed in the middle of the bottom of storage box 3 and a socket is installed on its front.

[0034] Press the electric button 102 on the table 1 to start the motor inside the shrink box 301. When the motor rotates forward, it drives the lead screw 305 to rotate, and the lead screw nut 304 moves upward along the lead screw 305. At the same time, the slider 303 slides upward along the slide rail 302, pushing the storage box 3 to rise. When the motor rotates in reverse, the storage box 3 retracts downward along the slide rail 302 into the shrink box 301, realizing the lifting and lowering adjustment of the storage box 3.

[0035] Connect the main power supply to the furniture table and start the refrigeration unit via electric button 102. After the compressor starts working, the temperature inside refrigerator 106 and refrigerator 2 107 gradually decreases. The refrigeration temperature can be adjusted via the button. When you need to store items, simply push or pull refrigerator 106 or refrigerator 2 107 to open the cabinet and put or take out items. After closing the cabinet, the glass panel can provide insulation and dust protection.

[0036] Small items can be categorized and placed in the compartmentalized storage areas of drawer 104 and drawer 205, or placed in storage cabinets 107, 208, 310, and 311 of storage box 3. The rotating rack 312 inside the storage cabinet can be used to hang small items. When the makeup function is needed, open the makeup mirror 306 on the front of the tiered cabinet 313 and turn on the LED light to illuminate the makeup application. External electrical appliances can be connected to the power supply through the socket on the electrical box 309. Mobile phones and other devices can be wirelessly charged by placing them in the wireless charging area 103.

[0037] Working principle: When the electric button 102 issues a lifting command, the motor inside the shrink box 301 receives the signal and starts. The motor output shaft drives the lead screw 305 to rotate around its own axis. Since the lead screw 305 and the lead screw nut 304 are threadedly connected, and the lead screw nut 304 is slidably connected to the slide rail 302 via the slider 303, the slider 303 restricts the rotation of the lead screw nut 304 with the lead screw 305, so that the lead screw nut 304 can only move linearly along the axis of the lead screw 305. Because the lead screw nut 304 is fixedly connected to the storage box 3, the linear movement of the lead screw nut 304 directly drives the storage box 3 to move up and down along the slide rail 302, ultimately achieving the lifting and lowering of the storage box 3.

[0038] The refrigeration function relies on a vapor compression refrigeration cycle, with the core being the coordinated operation of the refrigeration components. After the compressor starts, it compresses the refrigerant into a high-temperature, high-pressure gaseous state, which then enters the condenser. In the condenser, the high-temperature, high-pressure refrigerant releases heat through heat exchange with the outside air and condenses into a medium-temperature, high-pressure liquid state. This medium-temperature, high-pressure liquid refrigerant then passes through a throttling valve, causing a rapid pressure drop, transforming into a low-temperature, low-pressure gas-liquid mixture that enters the evaporator. The heat dissipation end of the evaporator is located inside the walls of refrigerator 106 and refrigerator 207. The low-temperature, low-pressure refrigerant absorbs heat from inside the refrigerator within the evaporator, vaporizing into a low-temperature, low-pressure gaseous state, simultaneously lowering the temperature inside the refrigerator and achieving the refrigeration effect. Finally, the low-temperature, low-pressure gaseous refrigerant is drawn back into the compressor and compressed again, thus repeating the cycle to maintain the low-temperature environment inside the refrigerator.
