SPECIFIC EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0025] This embodiment provides a community intelligent meal delivery cabinet, as Figures 1-7 shown. The delivery cabinet includes a cabinet body 1, a plurality of meal pickup openings 11 opened on the cabinet body 1 for picking up meals, and a cabinet door 2 arranged in the meal pickup opening 11; a heat preservation structure 3 is arranged inside the cabinet body 1. The heat preservation structure 3 includes a ceramic plate 31 arranged inside the cabinet body 1, a plurality of storage grooves 32 opened on the ceramic plate 31 for placing tableware, a cavity 33 opened inside the ceramic plate 31, an infrared disinfection lamp tube 34 arranged in the cavity 33, and a first through hole 35 opened on the ceramic plate 31 for communicating the storage groove 32 with the cavity 33. A temperature sensor 36 is arranged inside the storage groove 32. Through the design of the heat preservation structure 3, it is ensured that the meals can maintain an appropriate temperature inside the cabinet body 1, avoiding the meals from getting cold due to long-term placement, thus ensuring the eating taste and digestion and absorption of the elderly. The infrared disinfection lamp tube 34 can not only sterilize and disinfect the air inside the cavity 33 and the storage groove 32, but also heat and keep warm the meals to a certain extent, ensuring the safety and hygiene of the food. The user only needs to open the cabinet door 2, place the meals in the storage groove 32, then close the cabinet door 2 and start the infrared disinfection lamp tube 34, and the operation process is simple and fast. The appropriate temperature can effectively inhibit the growth of bacteria, thereby prolonging the freshness period of the meals and reducing food waste. The heat preservation structure 3 is composed of a ceramic plate 31, a storage groove 32, a cavity 33, an infrared disinfection lamp tube 34, a temperature sensor 36, etc. The ceramic plate 31 has good heat insulation performance and can reduce the loss of heat. The infrared disinfection lamp tube 34 in the cavity 33 generates heat during operation, and these heats are transferred to the inside of the storage groove 32 through the first through hole 35 on the storage groove 32 to heat and keep warm the meals. The temperature sensor 36 is used to monitor the temperature inside the storage groove 32 in real time to ensure that the meals are kept within an appropriate temperature range. The infrared rays emitted by the infrared disinfection lamp tube 34 have the function of sterilization and disinfection, and can destroy the DNA structure of bacteria and viruses, thereby achieving the purpose of sterilization and disinfection. At the same time, the heat generated by the infrared disinfection lamp tube 34 can also heat the air inside the cavity 33 and the storage groove 32 to further kill the bacteria and viruses in the air. When using this device, first open the cabinet door 2, place the meals through the meal pickup opening 11 inside the storage groove 32, and then close the cabinet door 2; then start the infrared disinfection lamp tube 34 to sterilize and disinfect the inside of the cavity 33 and the storage groove 32, and at the same time heat and keep warm the meals through the hot air generated by the sterilization and disinfection to ensure that the meals maintain an appropriate temperature inside the cabinet body 1, avoiding the meals from getting cold due to long-term placement and affecting the eating taste and digestion and absorption of the elderly.

[0026] Specifically, a controller 4 is provided on the cabinet body 1 and is connected to the infrared disinfection lamp tube 34 and the temperature sensor 36. A photovoltaic panel 41 connected to the controller 4 is provided at the upper end of the cabinet body 1 for supplying power to the infrared disinfection lamp tube 34. Through the connection of the controller 4 with the infrared disinfection lamp tube 34 and the temperature sensor 36, the intelligent monitoring and management of the internal environment of the distribution cabinet are realized. The controller 4 can automatically adjust the power of the infrared disinfection lamp tube 34 according to the data of the temperature sensor 36 to ensure that the meals are kept within a suitable temperature range, improving the accuracy and efficiency of management. The setting of the photovoltaic panel 41 enables the distribution cabinet to be powered by solar energy, reducing the dependence on traditional energy sources, lowering the operating cost, and also contributing to reducing carbon emissions, which is in line with the green and environmental protection development concept. Under the combined action of the intelligent temperature control and the infrared disinfection function, the freshness and safety of the meals during the distribution process can be ensured, improving the dining experience of the elderly and guaranteeing their dietary health. The temperature sensor 36 continuously detects the temperature in the storage slot 32 and transmits the data to the controller 4. The controller 4 automatically adjusts the power of the infrared disinfection lamp tube 34 according to the preset temperature range. When the temperature is lower than the set value, the controller 4 increases the power of the infrared disinfection lamp tube 34 to raise the temperature; when the temperature is higher than the set value, the power is reduced to avoid overheating. The photovoltaic panel 41 is located at the upper end of the cabinet body 1 and can receive sunlight and convert it into electrical energy. This electrical energy is transmitted to the controller 4, which in turn powers the infrared disinfection lamp tube 34, the temperature sensor 36, the controller 4 itself, etc. The electrical energy generated by the photovoltaic panel 41 not only meets the daily operating needs of the distribution cabinet but also realizes the self-sufficiency of energy, reducing the operating cost. The controller 4, as the core component of the entire system, is responsible for receiving the data from the temperature sensor 36 and making decisions according to the preset algorithms and logics. It can also monitor the working state of the photovoltaic panel 41 to ensure the stability and reliability of power supply. In addition, the controller 4 may also have the ability to communicate with a remote management system so that managers can monitor the operating state of the distribution cabinet in real time and make necessary adjustments.

[0027] More specifically, for the convenience of storing and collecting the excess power of the photovoltaic panel 41: a storage battery 42 is provided inside the cabinet body 1, and the storage battery 42 is electrically connected to the controller 4 and the photovoltaic panel 41. The setting of the storage battery 42 enables the excess power generated by the photovoltaic panel 41 to be stored, avoiding energy waste. In situations where solar energy cannot be directly utilized, such as when the light is insufficient or at night, the storage battery 42 can release the stored electrical energy to power devices such as the infrared disinfection lamp tube 34, ensuring the continuous operation of the distribution cabinet. By effectively utilizing the combination of the photovoltaic panel 41 and the storage battery 42, the dependence on the traditional power grid is reduced, and the operating cost is lowered. At the same time, the utilization of this green energy also helps to reduce carbon emissions, conforming to the environmental protection concept. When the light is sufficient, the photovoltaic panel 41 converts solar energy into electrical energy and transports the electrical energy to the storage battery 42 for charging through the controller 4. The controller 4 will monitor the charging status of the storage battery 42 to ensure that the storage battery 42 will not be overcharged to protect its service life. The storage battery 42 receives the electrical energy from the photovoltaic panel 41 and stores it. This stored electrical energy can be released when the light is insufficient or needed to power devices such as the infrared disinfection lamp tube 34, the temperature sensor 36, and the controller 4. The controller 4 will intelligently schedule the use of electrical energy according to the current lighting conditions, the power of the storage battery 42, and the power consumption requirements of the devices. When the light is insufficient or at night, the controller 4 will instruct the storage battery 42 to release electrical energy to power devices such as the infrared disinfection lamp tube 34, ensuring the normal operation of the distribution cabinet.

[0028] In order to improve the intelligent control of the cabinet door 2: A camera 21 for scanning codes and face recognition for meal collection is provided on the cabinet body 1. The cabinet door 2 is hinged within the meal collection opening 11. An intelligent lock 22 for fixing the movable end of the cabinet door 2 is provided within the meal collection opening 11. The intelligent lock 22 is electrically connected to the camera 21 and the controller 4. By means of scanning codes or face recognition for meal collection, the meal collection process is simplified and the meal collection efficiency is improved. The elderly do not need to carry additional meal collection vouchers and can quickly open the cabinet door 2 and obtain the meal just by the meal collection code on their smartphones or their own faces. The combined use of the intelligent lock 22, the camera 21 and the controller 4 ensures that only authenticated users can open the cabinet door 2, effectively preventing the risks of unauthorized access and theft of meals. The intelligent meal collection method reduces the cumbersome manual operations, enhances the dining experience of the elderly, and also reflects the meticulous care of the community for the elderly. When the elderly need to collect a meal, they only need to align the meal collection code on their smartphones with the camera 21, or align their faces with the camera 21 for face recognition authentication. The camera 21 will capture this information and transmit it to the controller 4. After receiving the information transmitted by the camera 21, the controller 4 will process it and match it with the preset user database. If the information matches successfully, that is, the user identity is confirmed to be legal, the controller 4 will send an unlocking instruction to the corresponding intelligent lock 22. After receiving the unlocking instruction from the controller 4, the intelligent lock 22 will automatically unlock the movable end of the cabinet door 2, allowing the elderly to open the cabinet door 2 to take out the meal. Once the cabinet door 2 is opened, the intelligent lock 22 will record this meal collection operation and feedback the relevant information to the controller 4 for recording and analysis. After the elderly take out the meal, they should close the cabinet door 2. The intelligent lock 22 will detect the closed state of the cabinet door 2 and send a feedback signal to the controller 4. Based on this information, the controller 4 can update the meal collection status in real time and provide accurate meal collection records for the management personnel.

[0029] In order to prevent the heat generated in the cavity 33 from being discharged through the storage slot 32 when taking meals, resulting in heat loss: A blocking structure 5 is provided inside the storage slot 32 for blocking the first through hole 35 when the cabinet door 2 is opened. The blocking structure 5 includes a movable frame plate 51 movably arranged in the storage slot 32 and a second through hole 52 opened on the movable frame plate 51 and corresponding to the first through hole 35. A limiting groove 53 is opened on one side of the movable frame plate 51 close to the storage slot 32. A limiting plate 54 fixedly connected to the inner wall of the storage slot 32 is arranged inside the limiting groove 53. A spring 55 for driving the movable frame plate 51 to move close to the cabinet door 2 is arranged between one end of the limiting plate 54 close to the cabinet door 2 and the limiting groove 53. The design of the blocking structure 5 effectively prevents the heat in the cavity 33 from being discharged through the storage slot 32 when the cabinet door 2 is opened, thereby reducing heat loss. This ensures that the meals can continuously maintain an appropriate temperature inside the cabinet body 1 and improves the heat preservation efficiency. When the cabinet door 2 is closed, the blocking structure 5 automatically opens the channel to allow the hot air in the cavity 33 to enter the storage slot 32 to sterilize the storage slot 32 and the meals therein. This enhances the sanitary performance of the delivery cabinet and guarantees food safety. The blocking structure 5 realizes automatic control through the cooperation of the spring 55 and the limiting plate 54. Without manual intervention, the blocking state can be automatically adjusted according to the opening and closing state of the cabinet door 2, improving the intelligent level of the system. Cabinet door 2 open state: When taking meals, the user opens the cabinet door 2. At this time, the elastic force of the spring 55 pushes the movable frame plate 51 to move in the direction close to the cabinet door 2. As the movable frame plate 51 moves, the second through hole 52 on it gradually misaligns with the first through hole 35. When one side end of the limiting groove 53 abuts against the limiting plate 54, the movable frame plate 51 completely blocks the first through hole 35, preventing the hot air in the cavity 33 from being discharged through the storage slot 32. Cabinet door 2 closed state: When the cabinet door 2 is closed, the cabinet door 2 will push the movable frame plate 51 to move in the direction away from the cabinet door 2. At this time, the movable frame plate 51 squeezes the spring 55 through the limiting groove 53 to make it contract and store energy. As the movable frame plate 51 moves, the second through hole 52 gradually aligns and communicates with the first through hole 35. At this time, the hot air in the cavity 33 enters the storage slot 32 through the first through hole 35 and the second through hole 52 to sterilize and heat-insulate the storage slot 32 and the meals therein.

[0030] For the convenience of tableware recycling: There is a recycling structure 6 on the cabinet body 1 for recycling tableware. The recycling structure 6 includes a storage groove 61 opened at the bottom of the cabinet body 1, a storage rack 62 arranged in the storage groove 61, and a sealing door 63 arranged at the port of the storage groove 61. A handle 631 is arranged on the sealing door 63. The setting of the recycling structure 6 enables the tableware to be recycled orderly and centrally, avoiding the situation of random placement of tableware, thereby improving the efficiency of tableware recycling. The design of the storage rack 62 can make full use of the space of the storage groove 61, enabling the tableware to be stored compactly. The setting of the sealing door 63 and the handle 631 makes the operation of the recycling structure 6 more convenient, and is also conducive to daily cleaning and maintenance work. When recycling, the diner places the used tableware on the storage rack 62. After the tableware is put in, the operator closes the sealing door 63 through the handle 631.

[0031] To improve the sealing performance at the connection between the sealing door 63 and the cabinet body 1: A sealing ring 12 is arranged on the cabinet body 1 for sealing the gap between the cabinet body 1 and the sealing door 63. The sealing ring 12 is made of rubber material and has good elasticity and sealing performance. The design of the sealing ring 12 can effectively fill the tiny gap between the cabinet body 1 and the sealing door 63, preventing external air, dust, water vapor and other impurities from entering the interior of the cabinet body 1, thereby improving the sealing performance of the cabinet body 1. When the sealing door 63 is closed, the sealing ring 12 is squeezed and elastically deformed, thus filling the gap between the cabinet body 1 and the sealing door 63. This elastic sealing effect can effectively prevent external air, dust and other impurities from entering the interior of the cabinet body 1. When the sealing door 63 is opened, the sealing ring 12 returns to its original shape under the action of elastic force, waiting for the next sealing operation. This process of repeated deformation and recovery will not reduce the sealing performance of the sealing ring 12, ensuring its long-term effectiveness.

[0032] For the convenience of cleaning the recycled tableware: a cleaning structure 7 for cleaning the tableware is provided on the cabinet body 1. The cleaning structure 7 includes a water tank 71 arranged in the cabinet body 1, a cleaning liquid 72 loaded in the water tank 71, a cleaning pipe 73 fixedly installed in the water tank 71, a spray head 74 fixedly arranged on the cleaning pipe 73, and a water pump 75 fixedly installed in the cabinet body 1 and communicated with the cleaning pipe 73. A first solenoid valve 76 is arranged between the output end of the water pump 75 and the cleaning pipe 73. A second solenoid valve 77 fixedly arranged on the cabinet body 1 and communicated with the water tank 71 is used to discharge the sewage in the water tank 71. The water pump 75, the first solenoid valve 76 and the second solenoid valve 77 are all connected to the controller 4. By starting the water pump 75 through the controller 4, the cleaning liquid 72 is conveyed into the cleaning pipe 73 and sprayed out through the spray head 74 to wash the tableware, realizing the automatic cleaning of the tableware and greatly improving the cleaning efficiency. The design of the cleaning structure 7 enables the cleaning liquid 72 to be recycled, reducing the waste of water resources. The design of the spray head 74 can ensure that the cleaning liquid 72 evenly and comprehensively covers the surface of the tableware, thereby effectively removing the dirt and residues on the tableware and improving the cleaning quality. When it is necessary to clean the tableware, the cleaning program is started through the controller 4. The controller 4 sends a signal to the water pump 75 and simultaneously opens the first solenoid valve 76. The water pump 75 starts to work, sucking the cleaning liquid 72 in the water tank 71 and conveying it into the cleaning pipe 73 through the pipeline. The cleaning liquid 72 flows in the cleaning pipe 73 and is evenly sprayed out through the spray head 74 to wash the tableware. After the cleaning is completed, the controller 4 closes the water pump 75 and the first solenoid valve 76, and simultaneously opens the second solenoid valve 77. The sewage in the water tank 71 is discharged through the second solenoid valve 77, realizing the replacement of the cleaning liquid 72 and the discharge of the sewage.

[0033] For the convenience of cooling the cavity 33: A cooling pipe 8 extending into the water tank 71 is inserted into the ceramic plate 31. A ring pipe 81 communicating with the top of the cooling pipe 8 is fixedly arranged on the cabinet body 1. The ring pipe 81 is connected to the output end of a water pump 75, and a third solenoid valve 82 is arranged between the ring pipe 81 and the output end of the water pump 75. The water pump 75 drives the cleaning liquid 72 to form a cycle between the cooling pipe 8 and the water tank 71, effectively absorbing and taking away the hot air in the cavity 33, achieving rapid cooling, and maintaining the stability of the environment in the storage slot 32. Using the existing cleaning liquid 72 for cooling treatment eliminates the need for additional cooling media, saving water resources and operating costs. In combination with the temperature sensor 36 and the controller 4, automatic control of the cooling process is realized, and the cooling intensity is automatically adjusted according to the actual temperature in the cavity 33 to ensure the optimal temperature in the storage slot 32. The temperature sensor 36 continuously monitors the temperature in the storage slot 32. When the detected temperature exceeds the rated value, a signal is sent to the controller 4. After receiving the signal of temperature exceeding the standard, the controller 4 immediately executes the cooling program. First, the first solenoid valve 76 is closed to stop the spraying and cleaning process of the cleaning liquid 72 to avoid conflicts with the cooling process. At the same time, the controller 4 opens the third solenoid valve 82 to allow the water pump 75 to pump the cleaning liquid 72 in the water tank 71 into the ring pipe 81. The cleaning liquid 72 flows in the ring pipe 81 and enters the cooling pipe 8 through the connecting pipe. The cooling pipe 8 extends into the cavity 33. When the cleaning liquid 72 flows through the cooling pipe 8, it absorbs the hot air in the cavity 33 to achieve the cooling effect. Subsequently, the heated cleaning liquid 72 falls back into the water tank 71 to form a cycle. The water pump 75 continuously operates to push the cleaning liquid 72 to circulate between the cooling pipe 8 and the water tank 71 until the temperature sensor 36 detects that the temperature in the storage slot 32 drops below the rated value. At this time, the controller 4 closes the third solenoid valve 82 to stop the cooling cycle and can restart the cleaning process as needed.
