Description

Technical Field

[0001] The present invention relates to the application field of refrigerators, and in particular to a vertical refrigerator with double-sided glass doors. Background Art

[0002] Refrigerator is a device used to store perishable items such as food and medicine at low temperatures. It slows down the growth of bacteria and keeps items fresh by lowering the internal temperature. Refrigerator is usually used in supermarkets, restaurants, laboratories and other places. Common types include household refrigerators and commercial refrigerators.

[0003] The working principle of the refrigerator is mainly to reduce the internal temperature through the refrigeration system, thereby keeping food and other items fresh. The refrigeration system includes: compressor (the compressor is the core part of the refrigeration system, which compresses the low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure gas and sends it to the condenser), condenser (in the condenser, the high-temperature and high-pressure refrigerant gas dissipates heat through metal pipes and releases heat to the outside. The gas gradually cools and turns into liquid), expansion valve (liquid refrigerant flows from the condenser into the expansion valve, which controls the flow of refrigerant and reduces its pressure, causing the liquid refrigerant to quickly evaporate into low-temperature and low-pressure gas) and evaporation. The refrigerator is also equipped with a temperature control system to ensure that the temperature remains within the set range (usually 2-8°C). The thermostat will detect the temperature inside the cabinet and control the start and stop of the compressor. When the temperature rises, the thermostat will start the compressor and restart the refrigeration cycle. When the temperature drops to the set value, the compressor will stop working to keep the temperature stable.

[0004] Currently, most refrigerators widely used in life are square. Some refrigerators with smaller storage capacity have correspondingly smaller door opening spaces, which requires multiple users to queue up in turn when taking items. This is especially true in supermarkets. The appearance and visual effects of traditional square refrigerators are average, and when there is a large flow of people, users have to wait in line for a long time to buy goods in the refrigerators, and the experience is poor.

[0038] See also Figure 13-15 The cooling air duct is a second load-bearing ventilation duct 18, and the second load-bearing ventilation duct 18 includes a second load-bearing tube 1801, and a second lower connecting tube 1802 and a second upper connecting tube 1803 are movably installed inside the second load-bearing tube 1801. Two groups of second extension blocks 1804 are symmetrically arranged on the sides of the second lower connecting tube 1802 and the second upper connecting tube 1803, and a second spring 1805 is arranged between the second lower connecting tube 1802 and the second upper connecting tube 1803 for connection. Two groups of strip grooves 1806 matching the movement trajectory of the second extension block 1804 are provided on the outside of the second load-bearing tube 1801. By setting the strip grooves 1806, the second load-bearing tube The rotation of 1801 will also synchronously drive the second lower connecting tube 1802 and the second upper connecting tube 1803 to rotate, and the outside of the second supporting tube 1801 is movably installed with two groups of threaded sleeves 1808 by opening an interlocking groove 1807. By setting the threaded sleeve 1808, the second extension block 1804 is pushed so that the second lower connecting tube 1802 and the second upper connecting tube 1803 can be close to each other, and the outside of the second supporting tube 1801 is rotatably connected to the outer movable tube 1809, and the outer movable tube 1809 is threadedly connected to the two groups of threaded sleeves 1808. Compared with the first supporting ventilation duct 11, the second supporting ventilation duct 18 is more convenient to operate and has better sealing.

[0039] The present invention is working in a specific way: Take Example 1 as an example: When the staff adds a new item for sale, the driving device 1201 will be turned off through the control panel, and the electromagnetic coupling of the transmission component 1203 will be cut off at the same time (the electromagnetic coupling is a mechanical device that realizes transmission through the electromagnetic principle. It is mainly used for connecting and transmitting torque, while providing a certain degree of adjustability and flexibility. The working principle of the electromagnetic coupling is usually based on the effect of the electromagnetic field, and the connection and separation of the coupling are controlled by the change of electromagnetic force). At the same time, in order to reduce energy consumption, the refrigeration module 6 will also be cut off, so that the refrigerator enters the material adding mode, and then the transmission mechanism 12 stops running as a whole. Then the staff opens the double-door glass door 4, and then opens the cover 1107, and then the staff opens the double-door glass door 4 and the cover 1107. The first extending block 1104 of the first lower connecting tube 1102 and the first upper connecting tube 1103 is dynamically squeezed, so that the first lower connecting tube 1102 and the first upper connecting tube 1103 are close to each other and the first spring 1105 is compressed, and then the first lower connecting tube 1102 is pulled out of the first base 8, and the first upper connecting tube 1103 is pulled out of the second base 16, keeping the two groups of first extending blocks 1104 in a pressed state, and moving the first bearing ventilation duct 11, so that the upper movable frame 15 slides along the upper guide rail 14, and the lower movable frame 10 slides along the lower guide rail 9, so that multiple groups of circular storage racks 5 installed on the outside of the first bearing tube 1101 can be moved out of the refrigerator. After the multiple groups of circular storage racks 5 are moved out, the staff can release the two groups of first extending blocks 1104.

[0040] Next, the staff can more conveniently add new items for sale to the multiple sets of circular racks 5. When adding, the circular racks 5 can be manually rotated to add. Since the electromagnetic coupling of the transmission component 1203 is disconnected, the first load-bearing ventilation duct 11 can be manually rotated. After the new items are added, the first load-bearing ventilation duct 11 is restored according to the above steps, and the driving device 1201 is started. The driving device 1201 drives the circular transmission shaft 1205 to rotate through the electromagnetic coupling. The circular transmission shaft 1205 drives the pulley component 1204 to work through the bevel gear set 1206. The pulley component 1204 drives the first load-bearing tube 1101 to rotate, and the first load-bearing tube 1101 and the first lower connecting tube 1102 and the first upper connecting tube 1103 are connected. A limiting groove is provided for interlocking installation, and then the first supporting tube 1101 will synchronously drive the first lower connecting tube 1102 and the first upper connecting tube 1103 to rotate, and then the first lower connecting tube 1102 drives the first base 8 to rotate, and the first upper connecting tube 1103 drives the second base 16 to rotate, and the first supporting tube 1101 drives multiple groups of circular shelves 5 to rotate slowly. The rotation of multiple groups of circular shelves 5 can better display the items for sale, and the cold air generated by the evaporator of the refrigeration module 6, under the operation of the axial flow fan on the top of the evaporator, the cold air enters the first supporting ventilation duct 11 through the first base 8, and the air supply fan 17 can suck and pull the cold air generated by the refrigeration module 6 to discharge it, so that the cold air circulates from top to bottom in the refrigerator, thereby improving the refrigeration effect.

[0041] Through the built-in program control design of the refrigerator, when the user opens the double-leaf glass door 4 to take an item, the electromagnetic coupling will be temporarily disconnected, causing the first load-bearing ventilation duct 11 and the multiple groups of circular shelves 5 to stop rotating, allowing the user to manually rotate the circular shelves 5 to select an item. When the user closes the double-leaf glass door 4, the electromagnetic coupling will automatically be energized, and under the drive of the drive device 1201, the first load-bearing ventilation duct 11 and the multiple groups of circular shelves 5 will continue to slowly rotate to display items.

[0042] Take Example 2 as an example: Compared with the first load-bearing ventilation duct 11 in Example 1, the second load-bearing ventilation duct 18 is easier to operate and has better sealing. The staff holds the circular storage rack 5 so that the second load-bearing tube 1801 cannot rotate, and then rotates the outer movable tube 1809, and uses the threaded engagement to make the two groups of threaded sleeves 1808 slide along the interlocking groove 1807 close to each other, and then the two groups of threaded sleeves 1808 push the second extension block 1804 to make the second lower connecting tube 1802 and the second upper connecting tube 1803 close to each other, and can also control the second lower connecting tube 1802 and the second upper connecting tube 1803 to retract into the second load-bearing tube 1801.

[0043] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiment without creative contribution as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
