Description

Technical Field

[0001] This utility model relates to the field of cake refrigerator technology, specifically to an automatic defrosting cake display refrigerator. Background Technology

[0002] Cake display refrigerators are commercial equipment that combine refrigeration and transparent display functions. They are suitable for bakeries, supermarkets, and other similar settings. Their core advantages lie in efficient refrigeration, energy-saving design, and enhanced product appeal. Cake display refrigerators are mainly used for refrigerating and displaying pastries, fruits, beverages, and other foods. They are suitable for cake shops, supermarkets, hotels, and other similar locations.

[0003] Water tends to accumulate on the inner walls of existing refrigerators, causing frost. As the frost thickens, it reduces the refrigerator's cooling efficiency and decreases its capacity. Therefore, the need for defrosting and de-icing is increasing. However, automatic defrosting and de-icing refrigerators typically use heating to defrost, which can damage the refrigerator's body. Furthermore, purely mechanical scraping can also damage the refrigerator.

[0004] To overcome the above-mentioned defects, the prior art (Chinese patent No. CN217483052U, published on 2022-09-23) discloses an automatic defrosting and de-icing refrigerator, including a cabinet body and a brine tank for storing brine. The upper inner side of the cabinet body is provided with a U-shaped tube, which is connected to the brine tank through an inlet pipe. This automatic defrosting and de-icing refrigerator, by providing a U-shaped tube, facilitates the introduction of brine into the inner wall of the cabinet body. The brine enters the baffle along the inner wall of the cabinet body, which facilitates the melting of frost on the baffle and the pivot. After a period of time, the frost becomes thinner and thinner under the action of the brine. Under the action of the electric telescopic rod, the baffle is pushed, causing the angle between the individual baffles to change. At this time, the adjacent baffles fold. Because the rubber layer is soft and easy to deform, and the surface of the rubber layer has a corrugated curve, it is easy to create a gap between the ice layer and the rubber layer, thereby causing the frost to detach, which facilitates the quick removal of frost without damaging the cabinet body.

[0005] While the above design can solve the aforementioned problems, during long-term use, due to temperature differences, a large amount of frost will form inside the refrigerator, making it impossible for customers to see the cakes clearly and quickly. In addition, when placing cakes, the existing design cannot stably open the cabinet door, requiring manual maintenance to keep the door open, which is inconvenient and may damage the cake's exterior. Utility Model Content

[0006] The purpose of this utility model is to provide an automatic defogging cake display refrigerator to solve the problems mentioned in the background art, such as the large amount of frost that will form inside the refrigerator during long-term use due to temperature differences, making it impossible for customers to see the cakes clearly and quickly. At the same time, when it is necessary to place the cakes, the existing design cannot stably open the cabinet door, and the door needs to be manually kept open during the cake placement process, which is not convenient and may damage the cake's exterior.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic defogging cake display refrigerator, comprising a refrigerator body and a hollow connecting rod, wherein vertical sliding inner grooves are provided on the left and right sides of the refrigerator body, and a transmission defogging mechanism for cleaning the opening and closing of the refrigerator door is installed inside the vertical sliding inner grooves, the transmission defogging mechanism includes a rotary drive motor, and the rotary drive motor is fixedly installed on the back of the refrigerator body, and a stabilizing and fitting rod is installed on the top of the refrigerator body, and an opening and closing stabilizing mechanism for supporting the opening and closing of the refrigerator door is installed on the outer surface of the stabilizing and fitting rod.

[0008] Furthermore, the opening and closing stabilizing mechanism includes a lower end return spring, which is fixedly installed on the lower surface of the refrigerator body. The front end of the lower end return spring is fixed to the lower inner surface of the opening and closing door, and a hollow limiting bending plate is installed on the outer surface of the stabilizing and fitting rod.

[0009] Furthermore, the hollow limiting bend plate is fixedly installed on the top of the opening and closing cabinet door, and the rotation trajectory of the hollow limiting bend plate is in contact with the outside of the stabilizing and fitting rod. A supporting rotating frame is installed on the top of the refrigerator body, and a semi-circular rotating rod is installed inside the supporting rotating frame.

[0010] Furthermore, the outer surface of the output end of the rotary drive motor is equipped with two driving worm gears, and a cleaning plate is installed inside the vertical sliding inner groove. The left and right ends of the cleaning plate are respectively nested and slidably installed inside the left and right sets of vertical sliding inner grooves, and two sets of rotating connecting rods are installed inside the upper and lower ends of the cleaning plate.

[0011] Furthermore, the hollow connecting rod has a threaded design inside, and the worm gears on both sides mesh with the inside of the hollow connecting rod. The outer surface of the cleaning plate is in contact with the inner surface of the cabinet door. Two sets of worm gears, hollow connecting rods and rotating connecting rods are symmetrically installed on both sides about the center point of the refrigerator body.

[0012] Furthermore, the interior of the refrigerator body is equipped with a cake rack, and the cabinet door is a symmetrical glass door design. The inner surface of the cabinet door contacts the outer surface of the cleaning board to form a sliding structure, and the outer surfaces of the worm gears on both sides contact the inner surfaces of the hollow connecting rods to form a meshing structure.

[0013] Furthermore, a toothed abutment block is installed on the inner surface of the hollow limiting bending plate, and the rotation trajectory of the toothed abutment block abuts against the lower arc of the semi-circular rotating rod. An abutment contraction spring is installed on the outer surface of the supporting rotating frame, and the front end of the abutment contraction spring is fixed to the outer surface of the semi-circular rotating rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are: When the cake display refrigerator with automatic defogging needs to be defrosted, the rotary drive motor is directly started to drive the two sets of hollow connecting rods on the left and right. At this time, the hollow connecting rods will be pulled inward to drive the rotating connecting rod, so that the upper and lower sets of contact cleaning plates slide against the inside of the cabinet door and complete the defrosting work in this process. This design can avoid the generation of a lot of fog and frost inside the refrigerator, and customers can quickly and clearly see the cake styles through the refrigerator and make quick selections.

[0015] Furthermore, when the cabinet door is opened outward, the toothed contact block will abut against the semi-circular rotating rod, causing it to rotate. After the contact is broken, the lower return spring will reset it again. The top of the semi-circular rotating rod cannot rotate in the opposite direction due to the abutment of the supporting rotating frame. This allows the cabinet door to always remain open. This design ensures that the equipment can keep the cabinet door stably open when cakes need to be placed, without the need for manual maintenance. This makes it convenient to place the cakes without damaging their exterior.

[0016] Furthermore, when the cabinet door is opened and closed and rotated outward, the hollow limiting plate will slide in a way that limits stability against the outside of the stabilizing rod. This design makes the equipment more stable and efficient to use. Attached Figure Description

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 2 , Figure 3 and Figure 4 This utility model provides the following technical solution: an automatic defrosting cake display refrigerator, comprising a refrigerator body 1 and a hollow connecting rod 5, wherein vertical sliding inner grooves 7 are provided on the left and right sides of the refrigerator body 1, as shown in the figure. Figure 3 As shown, the vertical sliding inner groove 7 is equipped with a transmission defogging mechanism for cleaning the opening and closing cabinet door 2. The transmission defogging mechanism includes a rotary drive motor 3, which is fixedly installed on the back of the refrigerator body 1. A stabilizing and fitting rod 13 is installed on the top of the refrigerator body 1, and an opening and closing stabilizing mechanism for supporting the opening and closing cabinet door 2 is installed on the outer surface of the stabilizing and fitting rod 13.

[0026] like Figure 2 , Figure 3 and Figure 4The technical solution shown addresses the problem that during prolonged use, temperature variations can cause excessive frost to form inside the refrigerator, preventing customers from clearly viewing cakes and making quick selections. The solution discloses the following: The output end of the rotary drive motor 3 has two worm gears 4 mounted on its outer surface; a cleaning plate 11 is installed inside the vertical sliding inner groove 7; the left and right ends of the cleaning plate 11 are nested and slidably installed inside the two sets of vertical sliding inner grooves 7; and two sets of rotating connecting rods 6 are installed inside the upper and lower ends of the cleaning plate 11. The hollow connecting rod 5 has a threaded design inside. Figure 4 As shown, the worm gears 4 on both sides mesh with the hollow connecting rod 5, and the outer surface of the cleaning plate 11 is in contact with the inner surface of the cabinet door 2. The worm gears 4 on both sides, the hollow connecting rod 5 and the rotating connecting rod 6 are symmetrically installed on the left and right sides about the center point of the refrigerator body 1. The cake rack 10 is installed inside the refrigerator body 1. The cabinet door 2 is a symmetrical glass door design. The inner surface of the cabinet door 2 contacts the outer surface of the cleaning plate 11 to form a sliding structure, and the outer surface of the worm gears 4 on both sides contacts the inner surface of the hollow connecting rod 5 to form a meshing structure.

[0027] After the refrigerator body 1 has been operating for a long time, a large amount of frost will appear inside the refrigerator body 1 and inside the rotating door 2 on the outside of the refrigerator body 1. When it is necessary to remove this frost efficiently, the rotary drive motor 3 fixedly mounted on the back of the refrigerator body 1 is activated. The two worm gears 4 fixedly mounted on both sides of the output end of the rotary drive motor 3 will be driven to rotate continuously. The rotation of the worm gears 4 will drive the hollow connecting rods 5 whose outer surfaces are in contact with each other, creating a meshing motion. Because the internal contact surface of the hollow connecting rods 5 is threaded, the hollow connecting rods 5 will move laterally horizontally along the outside of the two worm gears 4 during the meshing motion. Figure 4 As shown, during the movement of the hollow connecting rod 5, the rotating connecting rods 6 installed at both ends will be driven synchronously. At this time, since the end of the rotating connecting rod 6 is rotated and installed on the outer surface of the end of the cleaning plate 11, the cleaning plate 11 will slide vertically along the vertical sliding inner groove 7 opened on the side of the refrigerator body 1 as the rotating connecting rod 6 is driven. During the sliding process of the cleaning plate 11, its outer surface is always in contact with the inner surface of the opening and closing cabinet door 2. The design of the upper and lower sets of cleaning plates 11 will enable the frost inside the opening and closing cabinet door 2 to be thoroughly cleaned. This design makes the equipment more convenient to use.

[0028] Example 2: Figure 1 , Figure 5 and Figure 6The technical solution shown addresses the problem that existing designs cannot stably open the cabinet door when placing cakes, requiring manual maintenance to keep the door open during cake placement, which is inconvenient and may damage the cake's exterior. The solution discloses an opening and closing stabilizing mechanism including a lower return spring 12, which is fixedly installed on the lower surface of the refrigerator body 1. The front end of the lower return spring 12 is fixed to the lower inner surface of the opening and closing door 2. A hollow limiting bend 8 is installed on the outer surface of the stabilizing and fitting rod 13. Figure 5 As shown, the hollow limiting bending plate 8 is fixedly installed on the top of the opening and closing cabinet door 2, and the rotation trajectory of the hollow limiting bending plate 8 is in contact with the outside of the stable contact rod 13. The top of the refrigerator body 1 is equipped with a support rotating frame 14, and a semi-circular rotating rod 15 is installed inside the support rotating frame 14. The inner surface of the hollow limiting bending plate 8 is equipped with a toothed abutment block 9, and the rotation trajectory of the toothed abutment block 9 abuts against the lower arc of the semi-circular rotating rod 15. The outer surface of the support rotating frame 14 is equipped with an abutment contraction spring 16, and the front end of the abutment contraction spring 16 is fixed to the outer surface of the semi-circular rotating rod 15.

[0029] When stable opening and closing of the cabinet doors 2 is required, the left and right sets of cabinet doors 2 are directly fixed so that they open outward along the outside of the refrigerator body 1. The outward rotation of the cabinet doors 2 will synchronously rotate the hollow limiting bending plate 8 fixed at the top. During this rotation, the hollow limiting bending plate 8 will conform to the outside of the stabilizing contact rod 13 fixed at the top of the refrigerator body 1. This design makes the equipment more stable. During the rotation of the hollow limiting bending plate 8, the toothed abutment block 9 fixed on its outer surface will be synchronously driven. During the rotation of the toothed abutment block 9, it will abut against the lower end of the semi-circular rotating rod 15. Since the contact surface of the semi-circular rotating rod 15 is semi-circular, ... Figure 6 As shown, the semicircular rotating rod 15 is rotatably installed inside the support rotating frame 14. Therefore, after the semicircular rotating rod 15 is abutted, it will rotate within the support rotating frame 14. During the rotation of the semicircular rotating rod 15, it will abut against the front end of the abutment contraction spring 16 fixed outside the support rotating frame 14, so that the toothed abutment block 9 can quickly reset after disengaging from the semicircular rotating rod 15. Since the top of the semicircular rotating rod 15 is abutted by the support rotating frame 14, it cannot rotate in the opposite direction. The semicircular rotating rod 15 can then fix the opening and closing cabinet door 2 through the hollow limiting bending plate 8 and the toothed abutment block 9. When the opening and closing cabinet door 2 needs to be closed, the connecting handle 17 is pulled outward to pull the semicircular rotating rod 15 back to its original position. The opening and closing cabinet door 2 can then reset again through the abutment contraction spring 16 fixedly installed on the lower surface of the refrigerator body 1. This design makes the use of the equipment more stable.
