Description

Technical Field

[0001] The utility model relates to the technical field of refrigerated display cabinets, and particularly relates to a refrigerated display cabinet with a detachable cold air curtain. Background Technique

[0002] The important function of a refrigerated display cabinet is to protect the temperature of goods, keep the goods fresh and not easy to deteriorate. The cold air curtain refrigerated display cabinet uses the cold air curtain technology to maintain the temperature, and evenly distributes the cold air in the cabinet through the air curtain. It usually has no door and is suitable for high-traffic commercial environments. The cold air curtain can not only effectively reduce the temperature and maintain the display effect, but also facilitate customers to pick up goods.

[0003] There are many types of current refrigerated cabinets, including cold air curtain refrigerated display cabinets. After the common cold air curtain is installed and used for a certain period of time, it usually needs to be disassembled, cleaned and maintained. However, the traditional installation and disassembly methods of the cold air curtain are relatively cumbersome, which makes the disassembly and repair work more troublesome. This may lead to a longer downtime and higher maintenance costs. Moreover, since the cold air curtain display cabinet usually has no door body, the cold air in the refrigerated cabinet is easy to leak, thus increasing energy consumption.

The plug-in installation of the cold air curtain body 6 is facilitated through the cooperation of the slide plates 10 and the guide rails 7. The inside of the slide plates 10 is slidably connected to the inside of the guide rails 7. A first spring 11 is fixedly connected to the rear side of the inner cavity of the guide rail 7. The first spring 11 and the movable ring 12 can assist in pressing the slide plate 10 to take out the cold air curtain body 6. The front side of the first spring 11 is fixedly connected to the movable ring 12;

[0027] The guide rails 7 fixed to the bottom of the inner cavity of the fixed shell 5. Mounting members 8 for positioning the cold air curtain body 6 are arranged inside both fixed shells 5. The installation and disassembly of the cold air curtain body 6 are facilitated through the mounting members 8. The mounting member 8 includes a second spring 801, a first toothed plate 802, and a protective shell 806. Fixed frames 13 for supporting the cold air curtain body 6 are fixedly connected to the tops of both sides of the inner cavity of the refrigerated display cabinet body 1. The support work of the cold air curtain body 6 is facilitated through the setting of the fixed frames 13.

[0028] Universal self-locking wheels 14 are installed at the four corners of the bottom of the base 2. An air inlet groove 15 is opened at the front side of the inner cavity bottom of the refrigerated display cabinet body 1. The movement of the base 2 is facilitated through the universal self-locking wheels 14 to facilitate the replacement of the position of the refrigerated display cabinet body 1. A mounting plate 9 is installed on the front side of the fixed shell 5. A winding shell 16 is fixedly connected to the rear side of the mounting plate 9. The storage of the curtain 17 is facilitated through the winding shell 16. The curtain 17 is made of transparent plastic wrap material. The cooperation of the handle 18 and the clamping block 19 can protect the outside of the refrigerated display cabinet body 1, prevent external dust from falling in, and also reduce the loss of cold air. The curtain 17 is arranged inside the winding shell 16 through a spiral spring. A handle 18 is fixedly connected to the front side of the curtain 17. A clamping block 19 for cooperating with the curtain 17 is fixedly connected to the front side of the refrigerated display cabinet body 1.

[0029] The second spring 801 is fixed to one side of the inner cavity of the fixed shell 5. The first toothed plate 802 is fixed to one side of the sliding plate 10. One side of the second spring 801 is fixedly connected to a second toothed plate 803. Both the front and rear sides of one side of the second toothed plate 803 are fixedly connected to a pull rod 804. The end of the pull rod 804 away from the second toothed plate 803 penetrates to the outside of the refrigeration display cabinet body 1 and is fixedly connected to a pull plate 805. Open the cover plate 807. By pulling the movable pull plate 805 to drive the pull rod 804 to move, when the pull rod 804 moves, it will drive the second toothed plate 803 to squeeze the second spring 801. Subsequently, the second toothed plate 803 disengages from the surface of the first toothed plate 802. At this time, the cold air curtain body 6 can be taken out. The protective shell 806 is fixed to one side of the fixed shell 5. The protective shell 806 and the cover plate 807 are used to facilitate the protection of the pull plate 805 and the pull rod 804. The cover plate 807 is hinged to the top of the protective shell 806.

[0030] The top of the inner cavity of the base 2 is fixedly connected with a retaining shell 20 for collecting cold air. The bottom of the inner cavity of the base 2 is fixedly connected with an exhaust fan 21. The retaining shell 20 is used to temporarily store the cold air inhaled through the air inlet groove 15. Then, the exhaust fan 21 is used to pump the cold air circulating in the retaining shell 20 into the inside of the exhaust pipe 22. Then, it is blown into the inside of the refrigeration display cabinet body 1 again through the exhaust pipe 23 and the blowing pipe 24 for recycling, thereby reducing the energy consumption of the refrigerator. The front end of the exhaust fan 21 is communicated with an exhaust pipe 22. The top of the exhaust pipe 22 is communicated with the retaining shell 20. Both ends of the rear side of the exhaust fan 21 are communicated with an exhaust pipe 23. The end of the exhaust pipe 23 away from the exhaust fan 21 penetrates to both sides of the refrigeration display cabinet body 1 and is communicated with a blowing pipe 24. The surface of the blowing pipe 24 penetrates to the inside of the refrigeration display cabinet body 1. A retaining shell 25 for protecting the exhaust pipe 23 is sleeved on the surface of the exhaust pipe 23. The retaining shell 25 is used to facilitate the protection of the exhaust pipe 23. One side of the retaining shell 25 close to the refrigeration display cabinet body 1 is fixedly connected with the refrigeration display cabinet body 1. Both the front and rear sides of the retaining shell 25 are fixedly connected with reinforcing blocks 26. One side of the reinforcing block 26 is fixedly connected with the refrigeration display cabinet body 1. The fixed connection between the reinforcing block 26 and the refrigeration display cabinet body 1 can improve the connection strength between the retaining shell 25 and the refrigeration display cabinet body 1.

[0031] Working principle: When the user needs to disassemble the cold air curtain body 6, first remove the mounting plate 9 from the fixed shell 5, then push open the cover plate 807, and pull the movable pull plate 805 to drive the pull rod 804 to move. When the pull rod 804 moves, it will drive the second tooth plate 803 to squeeze the second spring 801, and then the second tooth plate 803 will be separated from the surface of the first tooth plate 802, and then the cold air curtain body 6 can be taken out. At the same time, the first spring 11 will also rely on its own elasticity to drive the movable ring 12 to assist in bouncing the slide plate 10, and the slide plate 10 will move within the internal limit of the guide rail 7, and then the cold air curtain body 6 can be taken out for maintenance. When the device is in normal use, the cold air blown down by the cold air curtain body 6 will enter through the air inlet slot 15, the retaining shell 20 will temporarily store the cold air, and then cooperate with the exhaust fan 21 to draw the cold air circulating in the retaining shell 20 into the exhaust pipe 22, and then blow it into the refrigeration display cabinet 1 again through the exhaust pipe 23 and the blowing pipe 24 for recycling, thereby reducing the energy consumption of the refrigeration cabinet, and the rewinding shell 16 is used to facilitate the storage of the baffle 17, and the baffle 17 is made of transparent plastic wrap, and can protect the outside of the refrigeration display cabinet 1 from external dust falling in while reducing the loss of cold air.
