Technical Field
[0001] The present invention relates to the technical field of fresh food express cabinets, and specifically to a multi-temperature zone community intelligent fresh food express cabinet system based on cold storage and energy storage. Background Art
[0002] It's common for modern people to find themselves without time for trips to the market or supermarket due to their fast-paced lives. Fresh produce, due to its short shelf life, perishability, and rapid deterioration, places high demands on cold chain logistics facilities and distribution. This has given rise to community fresh produce lockers with refrigeration and freezing capabilities. Existing refrigerated display cabinets suffer from a single temperature zone, high cost, and high energy consumption. A set of 20 standard compartments in a smart refrigerator consumes approximately 10 kilowatt-hours of electricity per day if using a conventional refrigeration unit. As community fresh produce lockers become more common, their energy consumption is increasing. Achieving precise, multi-temperature zones and low energy consumption for fresh produce lockers is a critical issue.
[0003] Existing semiconductor refrigeration systems mostly use a fan-and-fin air-cooling system. The operating principle of this semiconductor hot / cold box is as follows: A DC current is supplied to the semiconductor refrigeration plate in a specific direction, causing the temperature of one side inside the box to drop, becoming the cold end. The temperature of the side facing the outside of the box rises, becoming the hot end. Fans and fins located at the cold and hot ends absorb heat from the air inside the box, lowering the temperature. The hot end releases heat to the outside air, completing the cooling process. However, existing semiconductor hot / cold box technology suffers from significant heat loss through the semiconductor refrigeration plate when not in operation, frequent system startups and shutdowns, low system efficiency, and poor heat dissipation.
[0004] In response to the above problems, it is urgently necessary to carry out innovative designs based on the original structure of fresh food express cabinets. Summary of the Invention

DETAILED DESCRIPTION
[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] In a specific embodiment, Figure 1-Figure 7As shown, the basic usage process of the fresh food cabinet is disclosed: a heat dissipation branch pipe 11 is fixedly installed between the upper collecting square tube 8 and the lower collecting square tube 9, and a heat sink 10 is provided on the outside of the heat dissipation branch pipe 11, and the heat sink 10 is arranged corresponding to the placement cavity 7. The heat absorbed by the heat sink 10 can be transferred through the heat dissipation branch pipe 11.
[0027] A heat dissipation main pipe 13 is fixedly installed at the lower end of the upper collecting square tube 8, and a water pump 20 is fixedly installed at the lower end of the heat dissipation main pipe 13. The output end of the water pump 20 is fixedly installed with a buried pipe 12, and the end of the buried pipe 12 away from the water pump 20 is fixedly installed with a water tank 17. The water flow between the upper collecting square tube 8 and the water tank 17 can be made to flow to each other by utilizing the heat dissipation main pipe 13 through the water pump 20.
[0028] A connecting pipe 21 is fixedly installed on the outside of the water storage tank 17 , and one end of the connecting pipe 21 away from the water storage tank 17 is fixedly connected to the lower end of the lower collecting square pipe 9 .
[0029] A cold storage plate 14 and a heat preservation plate 16 are provided inside the placement cavity 7, and the cold storage plate 14 is located at the lower end of the placement cavity 7, and the heat preservation plate 16 is located on the side of the placement cavity 7 away from the switch box door 3. The cold storage plate 14 can reduce the temperature inside the placement cavity 7, and the heat preservation plate 16 can slow down the change of the temperature inside the placement cavity 7.
[0030] A refrigeration plate 18 is provided at one end of the insulation plate 16 away from the placement cavity 7 , and refrigeration pipes 15 are provided inside the refrigeration plate 18 and the cold storage plate 14 . The refrigeration plate 18 can use the refrigeration pipes 15 to reduce the temperature of the cold storage plate 14 .
[0031] A semiconductor refrigeration sheet 19 is provided on the side of the refrigeration plate 18 away from the insulation plate 16, and the semiconductor refrigeration sheet 19 is snap-fitted and installed inside the main body 1 of the smart fresh food express cabinet, and the side of the semiconductor refrigeration sheet 19 away from the refrigeration plate 18 is tightly fitted with the heat sink 10, and the heat sink 10 will absorb the heat at the hot end of the semiconductor refrigeration sheet 19.
[0032] When the power is turned on, the temperature of one side of the semiconductor refrigeration plate 19 in the box drops to become the cold end, and the temperature of the other side rises to become the hot end. The cold end and the cold end heat sink are in full contact. The refrigeration tube 15 passes through the refrigeration plate 18. The refrigerant in the tube cools the refrigerant in the cold storage plate 14 through the refrigerant and then radiates cooling to maintain the temperature in the box. When the indoor temperature does not reach the specified value, the water pump 20 is turned on first to maintain the temperature in the box by cooling the water tank 17. If the cooling capacity in the water tank 17 does not meet the requirements, the semiconductor refrigeration plate 19 is turned on. This can avoid frequent start and stop of the semiconductor device.
[0033] The hot end and the hot end heat sink 10 are in full contact, and the heat dissipation branch pipe 11 completely penetrates all the heat sinks 10. The heat of the hot end is taken away by water to achieve rapid heat dissipation of the heat sink 10. Since the heated water enters the ground to dissipate heat, the heat dissipation cycle is completed.
[0034] Fresh food delivery cabinets are generally set up at the entrance of residential communities. Currently, most newly built residential communities are separated from people and vehicles. In summer, the garage contains a large cold source. The temperature inside the garage is generally about 10°C lower than the outdoor temperature. It can also be cooled by air cooling at the heat dissipation end. One end of the air duct is introduced into the underground garage space nearby, and the cool air is blown to the heat sink 10 for heat exchange and then discharged.
[0035] The refrigerant of the cold storage plate 14 is configured according to different temperature requirements, and has different phase change points, which can maintain different problems. Near dusk, it is opened for a longer time to charge the cold storage plate 14 with cold and then freeze it to maintain the temperature at night. If the temperature exceeds the limit value, it can also be started by a battery or an external power supply.
[0036] Based on the above embodiments, Figure 1-Figure 4 As shown, the automatic power generation process of the smart fresh food express cabinet main body 1 is disclosed.
[0037] An intelligent fresh food express cabinet main body 1 and a display controller 2 nested and installed inside the intelligent fresh food express cabinet main body 1; a switch box door 3 is provided inside the intelligent fresh food express cabinet main body 1, a photovoltaic support plate 4 is fixedly installed on the upper end of the intelligent fresh food express cabinet main body 1, and a photovoltaic panel main body 5 is rotatably installed on the upper end of the photovoltaic support plate 4, and a placement cavity 7 is provided inside the intelligent fresh food express cabinet main body 1; a heat dissipation baffle 6 is fixedly installed on the side of the intelligent fresh food express cabinet main body 1 away from the switch box door 3, and an upper collecting square tube 8 and a lower collecting square tube 9 are respectively provided at the upper and lower ends of the heat dissipation baffle 6 close to the intelligent fresh food express cabinet main body 1.
[0038] When using the multi-temperature zone community smart fresh food express cabinet system based on cold storage and energy storage, power can be generated through the photovoltaic panel main body 5 to provide electricity for the internal power structure of the smart fresh food express cabinet main body 1, thereby reducing the loss of electricity used by residents.
