Description

Technical Field

[0001] This utility model relates to the field of food display technology, and in particular to an automatic circulating display device. Background Technology

[0002] Food display fixtures are professional equipment used in the retail, catering, and food industries. They aim to present merchandise in a scientific and aesthetically pleasing way, enhancing product appeal and optimizing the customer shopping experience. These fixtures feature a modular design, adaptable to different food types, such as fresh and refrigerated produce, baked goods, snacks, and beverages, meeting diverse display needs. However, existing display fixtures lack temperature control capabilities, making food susceptible to spoilage in hot summer or cold winter weather.

[0003] A search revealed that patent CN220403632U discloses a food display device for sales. This device uses a circulating pump to extract condensate and transport it through a water pipe. Since the water pipe is located at the back of the display case's interior, it absorbs heat from the interior and carries it away with the water flowing through the pipe. A pressure pump then delivers the water to a water tank, preventing excessively high temperatures inside the display case from affecting food quality. However, this device only allows food to be displayed in one direction, and the display space is very limited. If there are many onlookers, it cannot guarantee that users in every direction can see the displayed food. Therefore, further improvements are needed. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 As shown, an automatic circulating display device is disclosed, comprising a base 1, a display cabinet 2 on the upper surface of the base 1, the display cabinet 2 being cylindrical, a plurality of placement cavities 21 arranged from bottom to top on the outer side of the display cabinet 2, and a hollow cavity 22 in the middle of the display cabinet 2, with ventilation holes 23 between the plurality of placement cavities 21 and the hollow cavity 22, a cooling pipe 4 arranged inside the hollow cavity 22, a shaft tube 5 passing through and fixed in the middle of the bottom end of the display cabinet 2, the shaft tube 5 passing through the top wall of the base 1 and rotatably connected to the base 1 via a bearing, a motor 6 for driving the shaft tube 5 to rotate is installed inside the base 1, a water tank 9 is installed inside the base 1, and a cooling component 10 is installed on the outer wall of the water tank 9, a circulation pump 11 connecting the cooling pipe 4 and the water tank 9 is installed inside the base 1, and a controller is installed on the outer wall of the base 1.

[0023] In this embodiment, the controller adopts the SIMATIC KTP series, specifically the KTP400 Basic, which has a touch screen control. The controller controls the operation of various electronic components of the device.

[0024] The cooling assembly 10 includes a semiconductor cooling chip fixed to the outer wall of the water tank 9. The cooling side of the semiconductor cooling chip is attached to the surface of the water tank 9, and several fins are fixed to the cooling side of the semiconductor cooling chip. The several fins extend through the side wall of the water tank 9 into the interior of the water tank 9. A cooling fan is installed on the heat dissipation side of the semiconductor cooling chip.

[0025] In this embodiment, the semiconductor cooling chip is the TEC1-12715 of the TEC1-127XX series. The semiconductor cooling chip can cool the fins, and then the fins can cool the water in the water tank 9. The cooling fan on the heat dissipation side can ensure normal heat dissipation on the heat dissipation side of the semiconductor cooling chip, thereby ensuring that the semiconductor cooling chip can operate normally.

[0026] The base 1 has multiple heat dissipation vents 12 on its side wall, and the heat dissipation vents 12 are equipped with dustproof meshes.

[0027] By setting the heat dissipation vent 12, the various electronic components inside the base 1 can be ensured to dissipate heat.

[0028] One end of the cooling pipe 4 passes through the inside of the shaft tube 5 and is connected to the outlet of the circulating pump 11. The inlet of the circulating pump 11 is connected to the water tank 9 through a pipe. The other end of the cooling pipe 4 passes through the inside of the shaft tube 5 and is connected to the water tank 9.

[0029] The circulating pump 11 can extract the cooled water from the water tank 9 and pump it into the cooling pipe 4. The cooling pipe 4 cools the air in the hollow cavity 22. The cold air can pass through the vent 23 and exchange heat with the air in the placement cavity 21, thereby cooling the placement cavity 21 and ensuring that the food placed in the placement cavity 21 remains fresh.

[0030] Several placement cavities 21 are arranged in a ring on the outside of the display case 2. A gear ring 8 is fixed on the outer wall of the shaft tube 5. A drive gear 7 is fixed at the output end of the motor 6. The drive gear 7 meshes with the gear ring 8.

[0031] In this embodiment, the motor 6 is a geared motor. After the motor 6 drives the drive gear 7 to rotate, the drive gear 7 drives the gear ring 8 to rotate, thereby driving the shaft tube 5 and the entire display cabinet 2 to rotate, so that people from different directions can see the food in the placement cavity 21 at different positions.

[0032] The lower surface of the display case 2 has several grooves 24, and each groove 24 is rotatably connected to a roller 3, with the bottom of the roller 3 fitting against the upper surface of the base 1.

[0033] During the rotation of display case 2, the rollers 3 can support display case 2.

[0034] A transparent cover 14 is fixed to the outside of the display case 2, and a top plate 13 is fixed to the top of the transparent cover 14. A side door 15 is connected to the side wall of the transparent cover 14 by hinges.

[0035] In this embodiment, the transparent cover 14 is made of transparent acrylic material. A side opening is opened on one side of the transparent cover 14. The side door 15 is rotatably connected to the side opening by a hinge. The side of the side door 15 away from the hinge is fixedly connected to the transparent cover 14 by a latch. Rotating and opening the side door 15 makes it convenient to place food inside the placement cavity 21 or to take food out of the placement cavity 21.

[0036] Working principle: When in use, food is placed in the placement cavity 21 for display. During the display, the controller controls the circulation pump 11 to pump cold water from the water tank 9 into the refrigeration pipe 4. The refrigeration pipe 4 is used to refrigerate the hollow cavity 22 and the placement cavity 21 of the display cabinet 2 to ensure the freshness of the food. At the same time, the motor 6 drives the entire display cabinet 2 to rotate so that people from different directions can see the food in the placement cavity 21 at different positions.
