Description

Technical Field

[0001] This utility model relates to the field of refrigerator accessories technology, specifically a water receiving box for a frost-free refrigerator and a frost-free refrigerator. Background Technology

[0002] In frost-free refrigerators, the evaporator gradually frosts up during operation. To ensure cooling efficiency, periodic defrosting is necessary. During defrosting, the frost or ice on the evaporator surface melts into water droplets. If these water droplets are not drained in time, they accumulate inside the refrigerator, leading to accelerated icing, which in turn affects cooling performance and increases energy consumption. Therefore, refrigerator manufacturers typically design a drainage system to direct the water generated during defrosting outside the refrigerator.

[0003] Normally, the drainage system directs water into a drip tray located on the outside of the refrigerator. This tray collects and temporarily stores defrost water, preventing overflow and maintaining a clean environment. However, this design has introduced new problems: existing drip trays are made of rigid plastic, and some protrude about 6 centimeters from the refrigerator, taking up extra space and increasing the overall size of the refrigerator. Especially in packaging and transportation, the increased size of a single refrigerator significantly reduces the space utilization of the shipping container, thus reducing the quantity shipped per trip and indirectly increasing logistics costs. Furthermore, the rigid plastic of the drip tray makes it susceptible to damage during transport.

[0004] Therefore, optimizing the structure and layout of the water collection box while ensuring effective drainage, and reducing its impact on the overall size of the refrigerator, has become a noteworthy issue in refrigerator design. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a water receiving box for an air-cooled refrigerator and an air-cooled refrigerator.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A water collection box for an air-cooled refrigerator includes a back plate and an end plate that are parallel to each other. The back plate is used to connect to the refrigerator. A foldable accordion plate is connected between the back plate and the end plate. The foldable accordion plate, the back plate and the end plate form an upward-opening cavity structure.

[0007] The foldable accordion panel design ensures that the water collection box can be compressed and folded during refrigerator packaging and transportation, minimizing the overall size of the refrigerator. When in use, the foldable accordion panel of the water collection box can be unfolded to maintain the water collection capacity of the water collection box and not affect the original performance of the refrigerator.

[0008] The two ends of the back panel protrude from the foldable accordion panel and are respectively provided with connection holes for connecting bolts to fix the back panel to the refrigerator.

[0009] The back plate and end plate are respectively provided with a number of reinforcing ribs to ensure the structural strength of the back plate and end plate.

[0010] The back panel has a protrusion on the side away from the refrigerator. A foldable accordion plate extends from the lower part of the protrusion. One end of the protrusion is close to the top of the back panel, and an overflow hole is opened in the center of the protrusion.

[0011] The back panel, foldable accordion panel, and end panel are integrally molded structures and can be processed by injection molding or other methods.

[0012] A recessed clearance groove is provided at the center of the top surface of the back panel. The internal drainage system of the refrigerator has a drain pipe that runs out from the rear panel of the refrigerator and extends into the water collection box. The recessed clearance groove is used to make way for the drain pipe. During packaging and transportation, because the drain pipe is located at a low position, the end plate of the water collection box and the foldable accordion plate can protect the drain pipe.

[0013] A type of air-cooled refrigerator includes a refrigerator body, and the aforementioned water collection box is connected to the rear panel of the refrigerator body.

[0014] The rear panel of the refrigerator body is equipped with a drain pipe. One end of the drain pipe is connected to the drainage system inside the refrigerator body, and the other end extends into the water collection box.

[0015] An evaporation structure is installed inside the water receiving box. The evaporation structure is electrically connected to the main body of the refrigerator. The end plate and foldable bellows plate of the water receiving box can protect the evaporation structure.

[0016] The beneficial effects achieved by this utility model are: This utility model has a simple and novel structural design, is easy to install, and is highly practical.

[0017] Among them, the water collection box adopts a foldable accordion structure. This innovative design shows significant advantages in the packaging and transportation stage of the refrigerator: the foldable accordion can be compressed and folded, which greatly reduces the space occupied by the water collection box, thereby effectively controlling the overall volume of the refrigerator, which helps to reduce transportation and storage costs and improve logistics loading efficiency. In actual use, users can easily restore the original shape and capacity of the water collection box by simply pulling out the foldable accordion panel, fully meeting the needs of defrosting drainage without affecting the normal operation and performance of the refrigerator. This design balances the economy and convenience of production and transportation while ensuring the integrity and reliability of the end product's functions. Attached Figure Description

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Example: like Figures 2-4 As shown, a water collection box for a frost-free refrigerator includes a back plate 41 and an end plate 43 that are parallel to each other. The back plate 41 is attached to and connected to the rear panel 2 of the refrigerator. A foldable accordion plate 42 is connected between the back plate 41 and the end plate 43. The foldable accordion plate 42, the back plate 41 and the end plate 43 form an upward-opening cavity structure to receive water discharged from the drain pipe 5.

[0022] The two ends of the back plate 41 protrude from the foldable accordion plate 42 and are respectively provided with connecting holes 48. The connecting holes 48 are used to connect bolts to fix the back plate 41 to the rear panel 2 of the refrigerator.

[0023] The back plate 41 and the end plate 43 are respectively provided with a number of reinforcing ribs 45 to ensure the structural strength of the back plate 41 and the end plate 43. The reinforcing ribs 45 include vertical, horizontal and inclined directions.

[0024] A boss 46 is provided on the side of the back panel 41 away from the refrigerator (i.e., the side inside the cavity). A foldable bellows panel 42 extends through the lower part of the boss 46. One end of the upper part of the boss 46 is close to the top of the back panel 41. An overflow hole 47 is provided in the center of the boss 46. When the water inside the water collection box 4 is higher than the overflow hole 47, it will flow outward from the overflow hole 47. The lower part of the overflow hole 47 can be connected to a spare pipe and a spare water collection structure to prevent the evaporation structure inside the water collection box 4 from failing and causing water to overflow to various places.

[0025] The back plate 41, the foldable accordion plate 42, and the end plate 43 are integrally formed structures and can be processed by injection molding.

[0026] like Figure 1 As shown, a frost-free refrigerator includes a refrigerator body 1, and a water collection box 4 as described above is connected to the rear panel 2 of the refrigerator body 1.

[0027] The rear panel 2 of the refrigerator body 1 is provided with a drain pipe 5. One end of the drain pipe 5 is connected to the drainage system inside the refrigerator body 1, and the other end extends into the water collection box 4.

[0028] A recessed clearance groove 44 is provided at the center of the top surface of the back plate 41. The recessed clearance groove 44 is used to make way for the drain pipe 5. During packaging and transportation, since the drain pipe 5 is in a low position, the end plate 43 of the water receiving box 4 and the foldable bellows plate 42 can protect the drain pipe 5.

[0029] An evaporation structure is installed inside the water collection box 4. The evaporation structure is electrically connected to the refrigerator body 1 via wires 3. The end plate 43 and the foldable bellows plate 42 of the water collection box 4 can protect the evaporation structure. The evaporation structure can be an electrically heated structure, so that the water in the water collection box 4 evaporates continuously, ensuring that no water overflows from the water collection box 4.
