Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a double-layer water collection box for an air-cooled refrigerator. Background Technology

[0002] During the operation of an air-cooled refrigerator, the refrigeration system will generate a large amount of water due to condensation. If the water is not effectively treated, it will not only corrode the internal structure of the equipment and shorten its service life, but may also cause safety hazards such as short circuits.

[0003] Traditional frost-free refrigerator water collection boxes have several shortcomings: First, the water treatment method is limited to simple collection without evaporation or drainage design, leading to prolonged water retention, which can breed bacteria and produce odors. Second, the connection between the water collection box and the refrigerator is unstable, making it prone to leakage and detachment, affecting the normal operation of the equipment. Third, the water collection box is inconvenient to disassemble for cleaning and component replacement, especially the key components used for evaporating water, which are difficult to replace quickly, resulting in high maintenance costs and low efficiency. Fourth, the water level cannot be visually observed, making it easy for water to overflow and cause equipment malfunction. Utility Model Content

[0004] The purpose of this utility model is to provide a double-layer water collection box for air-cooled refrigerators to solve the problems of poor water accumulation, unstable connection, inconvenient maintenance, and inability to intuitively monitor water level in traditional air-cooled refrigerator water collection boxes.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A double-layer water collection box for a frost-free refrigerator includes an upper water collection box and a lower water collection box below the upper water collection box. An overflow column is provided on the upper surface of the inner cavity of the upper water collection box. A guide hole penetrating the bottom plate of the upper water collection box is opened in the center line of the overflow column. Two sets of evaporation sponges are provided on one side wall of the upper water collection box.

[0007] Furthermore, the upper surface of the upper water receiving box is provided with a flange, which is provided with several lugs and through holes for insertion into the air-cooled refrigerator and connection by screws passing through the through holes. The inner wall of the upper water receiving box has two sets of square holes, and a first L-shaped groove is provided below each of the square holes. The lower surface of the flange is provided with a second L-shaped groove corresponding to the position of the first L-shaped groove. Slider blocks are provided on both sides below the upper water receiving box.

[0008] Furthermore, the evaporating sponge is sequentially inserted into the second L-shaped groove, the square hole, and the first L-shaped groove for easy replacement. One end of the evaporating sponge is located outside the upper water receiving box and is in contact with the air. When the accumulated water comes into contact with the evaporating sponge, the water is absorbed and evaporates through the end in contact with the air.

[0009] Furthermore, the lower water receiving box has sliding grooves on both sides of its upper surface, which are adapted to and connected to the slider. A sealing strip is provided on the upper surface of the lower water receiving box, and a transparent plate is provided in the middle of one side wall of the lower water receiving box to facilitate observation of the water level.

[0010] Furthermore, the height of the upper surface of the overflow column is lower than the height of the lower surface of the square hole, and the inner cavity of the upper water receiving box and the overflow column together form a communicating vessel. When the water level is higher than the height of the overflow column, the accumulated water will flow into the lower water receiving box through the guide hole.

[0011] Beneficial effects: This utility model has the following beneficial effects:

[0012] 1. The double-layer water receiving box, together with the overflow column and the evaporation sponge, absorbs the water from evaporation through the evaporation sponge. When the water level is too high, the overflow column forms a communicating vessel structure that allows the water to flow into the lower water receiving box through the guide hole, avoiding water stagnation, reducing bacterial growth and odor, and preventing equipment corrosion.

[0013] 2. The lugs and through holes on the flange of the upper water receiving box are inserted into the air-cooled refrigerator and connected by screws. The sliding groove of the lower water receiving box is compatible with the sliding block of the upper water receiving box. In addition, the sealing strip is used for sealing. The multiple structures ensure that the water receiving box is firmly connected to the air-cooled refrigerator, prevents water leakage and detachment, and ensures the safe operation of the equipment.

[0014] 3. The evaporating sponge adopts an interlocking installation with L-shaped grooves and square holes, which makes disassembly and replacement simple and quick without complicated tools and operations, reducing maintenance costs. The transparent panel design of the lower water receiving box makes it easy to observe the water level and deal with accumulated water in time to prevent overflow.

[0015] 4. The water collection box automatically diverts water using the principle of communicating vessels and evaporates water naturally using an evaporating sponge. Its scientific structural design improves water treatment efficiency and reduces energy consumption. At the same time, the components work together to ensure the stable and efficient operation of the water collection box. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Combination Figures 1-4 The double-layer water collection box of the air-cooled refrigerator shown includes an upper water collection box 1 and a lower water collection box 2 below the upper water collection box 1. An overflow column 3 is provided on the upper surface of the inner cavity of the upper water collection box 1. A guide hole 4 is opened in the center of the overflow column 3, which penetrates the bottom plate of the upper water collection box 1. Two sets of evaporation sponges 5 are provided on one side wall of the upper water collection box 1. In view of the problem that the traditional water collection box has a single water treatment and is prone to overflow, the double-layer water collection box structure forms a dual protection mechanism of "evaporation-guide".

[0024] The upper water receiving box 1 has a flange 101 on its upper surface. The flange 101 has several lugs 102 and through holes 103. The lugs 102 are initially positioned and inserted into the air-cooled refrigerator. Screws pass through the through holes 103 and are tightened to form a stable vertical connection. Two sets of square holes 104 are opened on one side wall of the inner cavity of the upper water receiving box 1. A first L-shaped groove 105 is provided below each of the square holes 104. A second L-shaped groove 106 is provided on the lower surface of one end of the flange 101 corresponding to the position of the first L-shaped groove 105. Slider blocks 107 are provided on both sides below the upper water receiving box 1.

[0025] The evaporating sponge 5 is sequentially connected to the second L-shaped groove 106, the square hole 104, and the first L-shaped groove 105 for easy replacement. One end of the evaporating sponge 5 is located outside the upper water receiving box 1 and is in contact with the air. When the accumulated water comes into contact with the evaporating sponge 5, the water is absorbed and evaporates through the end in contact with the air. The installation design of the evaporating sponge 5 cleverly combines functionality and convenience. The first L-shaped groove 105, the second L-shaped groove 106, and the square hole 104 form a Z-shaped installation channel, allowing the evaporating sponge 5 to be quickly inserted or removed along a specific trajectory, greatly reducing maintenance costs and time. At the same time, one end of the evaporating sponge 5 is exposed outside the upper water receiving box 1, making full use of airflow to accelerate water evaporation. Compared with the traditional single collection method, it significantly improves the efficiency of water treatment and reduces odor generation.

[0026] The lower water receiving box 2 has sliding grooves 201 on both sides of its upper surface. The sliding grooves 201 are adapted to connect with the slider 107. A sealing strip 202 is provided on the upper surface of the lower water receiving box 2. The sliding grooves 201 and the slider 107 engage with the sealing strip 202 on the upper surface to form a sealing structure, which effectively prevents water leakage. A transparent plate 203 is set in the middle of one side wall of the lower water receiving box 2 to facilitate observation of the water level. Operators can directly observe the water level changes in the lower water receiving box 2, clean up the water in time, and avoid equipment failure due to water overflow.

[0027] The upper surface of the overflow column 3 is lower than the lower surface of the square hole 104. The inner cavity of the upper water receiving box 1 and the overflow column 3 together form a communicating vessel. When the water level is higher than the height of the overflow column 3, the accumulated water will flow into the lower water receiving box 2 through the guide hole 4, preventing the upper water receiving box 1 from overflowing due to excessive water level. This structure does not require additional power to drive it and relies on physical principles to achieve automatic water transfer. It saves energy and improves the overall water carrying capacity of the water receiving box through the complementary capacity of the upper and lower layers, ensuring the safety and stability of the air-cooled refrigerator during long-term operation.
