Refrigerator ice melting drainage structure

Abstract

This utility model relates to the field of refrigerator technology and discloses a refrigerator defrosting and drainage structure, including a drainage pipe: the top of the drainage pipe has four guide grooves, which are evenly distributed circumferentially around the axis of the drainage pipe. An installation block is provided at the top of the drainage pipe, and a filter bag is installed at the bottom of the installation block. In this refrigerator defrosting and drainage structure, after the installation block is correctly installed inside the drainage pipe, the melt water generated during defrosting first flows through the installation block and then enters the filter bag below it. The filter bag, as the core filtration unit, effectively intercepts impurities in the water flow, allowing only clean water to pass through its surface pores and drain into the main body of the drainage pipe below, where it is finally discharged. The presence of the filter bag fundamentally prevents impurities from adhering to and accumulating on the inner wall of the drainage pipe, thereby significantly reducing the risk of pipe blockage and ensuring the long-term smooth operation of the drainage system.

Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, and in particular to a refrigerator ice-melting drainage structure. Background Technology

[0002] When a refrigerator is in use, temperature changes occur inside. During this process, water will liquefy when heated and solidify when cooled. Therefore, current refrigerators need to be equipped with a drainage structure to drain the liquefied water inside.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: When using existing drainage structures, food debris inside the refrigerator is prone to clogging the drain pipe, making it difficult to drain water, affecting the drainage effect, and making it inconvenient to clean after clogging. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the drainage pipe is easy to be blocked and difficult to clean. To this end, we propose a refrigerator ice melting drainage structure.

[0005] To achieve the above objectives, this application adopts the following technical solution: a refrigerator ice-melting drainage structure, including a drainage pipe: a guide groove is provided at the top of the drainage pipe, the number of the guide grooves is four, the guide grooves are evenly distributed in a circle around the axis of the drainage pipe, an installation block is provided at the top of the drainage pipe, a filter bag is installed at the bottom of the installation block, and a locking block that is slidably connected to the guide groove is fixed around the installation block.

[0006] Preferably, a sealing groove is provided at the top of the drainage pipe. A sealing ring is installed inside the sealing groove, and four sealing blocks that cooperate with the guide groove are provided at the bottom of the sealing ring. Both the sealing ring and the sealing blocks are made of rubber.

[0007] Preferably, the bottom of the mounting block is fixed with four limiting strips, all of which are disposed on the outer surface of the filter bag and are evenly distributed in a circle around the axis of the filter bag.

[0008] Preferably, a bottom support ring is fixed to the bottom of the limiting strip, and the bottom support ring is located on the outer surface of the bottom of the filter bag.

[0009] Preferably, the top of the mounting block is provided with a guide groove, which is a tapered structure that is wider at the top and narrower at the bottom.

[0010] Preferably, a plurality of guide vanes are fixed on the inner surface of the drainage pipe, and the guide vanes are evenly distributed in a circle around the axis of the drainage pipe.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] In this invention, after the mounting block is correctly installed inside the drain pipe, the melt water generated during the defrosting of the refrigerator first flows through the mounting block and then enters the filter bag below it. As the core filtration unit, the filter bag effectively intercepts impurities in the water flow, allowing only clean water to pass through the pores on its surface and flow into the main body of the drain pipe below, where it is finally discharged. The presence of the filter bag fundamentally prevents impurities from adhering to and accumulating on the inner wall of the drain pipe, thereby significantly reducing the risk of pipe blockage and ensuring the long-term smooth operation of the drainage system.

[0019] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0020] Reference Figures 1-4As shown, this utility model provides a technical solution: a refrigerator ice-melting drainage structure, including a drainage pipe 1: the top of the drainage pipe 1 is provided with a guide groove 2, the number of guide grooves 2 is four, the guide grooves 2 are evenly distributed in a circle around the axis of the drainage pipe 1, the top of the drainage pipe 1 is provided with an installation block 3, the bottom of the installation block 3 is provided with a filter bag 4, and the four sides of the installation block 3 are fixed with a locking block 5 that is slidably connected to the guide groove 2, and the top of the drainage pipe 1 is provided with a sealing groove 6. A sealing ring 7 is installed inside the sealing groove 6. Four sealing blocks 8, which cooperate with the guide groove 2, are located at the bottom of the sealing ring 7. Both the sealing ring 7 and the sealing blocks 8 are made of rubber. During installation, the locking block 5 at the bottom of the mounting block 3 is precisely aligned with the guide groove 2 at the top of the drain pipe 1. The mounting block 3 is then pressed down. At this time, the locking block 5 will slide along the guide groove 2 and finally engage and lock, thus securely installing the mounting block 3 along with its bottom filter bag 4 into the drain pipe 1. During drainage, the water generated by the refrigerator defrosting first flows into the mounting block 3, and then into the filter bag 4 below it. The filter bag 4 plays a core filtration role, and its surface... The dense pores effectively intercept impurities and suspended particles in the water, allowing only clean water to flow through and drain into the main body of the lower drain pipe 1, where it is eventually discharged smoothly. The filter bag 4 fundamentally prevents impurities from adhering to the inner wall of the drain pipe 1, significantly reducing the risk of pipe blockage. When maintenance is required, if a large amount of impurities accumulate inside the filter bag 4, affecting the filtration efficiency, simply pull up the mounting block 3 to easily remove the mounting block 3 and the filter bag 4 from the drain pipe 1 for thorough cleaning or replacement. This modular design greatly simplifies the cleaning process and significantly improves the convenience and overall efficiency of maintenance operations.

[0021] Reference Figure 3 and Figure 4 As shown in this embodiment: four limiting strips 9 are fixed to the bottom of the mounting block 3. The four limiting strips 9 are all set on the outer surface of the filter bag 4. The four limiting strips 9 are evenly distributed in a circle around the axis of the filter bag 4. A bottom support ring 10 is fixed to the bottom of the limiting strips 9. The bottom support ring 10 is located on the outer surface of the bottom of the filter bag 4. The circumferentially distributed limiting strips 9 form an effective constraint on the side wall of the filter bag 4 like a skeleton, which significantly suppresses the risk of excessive expansion and deformation caused by the continuous deposition and accumulation of impurities inside the filter bag 4. The bottom support ring 10 at the bottom is like a support base, which provides key support for the bottom of the filter bag 4. It effectively avoids the filter bag 4 being pulled downward excessively under its own weight, water flow impact and the weight of impurities over a long period of time, which would lead to rupture. The two work together to ensure the structural integrity and filtration function stability of the filter bag 4 during long-term use.

[0022] Reference Figure 1As shown in this embodiment: the top of the mounting block 3 is provided with a guide groove 11, which is a conical structure that is wider at the top and narrower at the bottom. The guide groove 11 adopts a unique conical structure design that is wider at the top and narrower at the bottom. This structural design significantly optimizes the water inlet process. Its wide upper port is like a funnel, which can effectively receive and collect the defrosting water flowing down from above. As the water flows down along the inner wall of the cone, the channel cross-section gradually narrows, forming a natural guiding and converging effect. This not only guides the direction of water flow, but also accelerates the water flow under the action of gravity, ensuring that all defrosting water entering the guide groove 11 can quickly and centrally flow into the drain pipe 1 below, thereby effectively avoiding the phenomenon of water splashing, dispersing or stagnating at the inlet, and greatly improving the efficiency and reliability of the drain inlet.

[0023] Reference Figure 2 As shown in this embodiment: multiple guide vanes 12 are fixed on the surface inside the drainage pipe 1. The guide vanes 12 are evenly distributed in a circle around the axis of the drainage pipe 1. When water flows through the drainage pipe 1, the evenly distributed guide vanes 12 force the water flow direction to change, causing it to flow along a specific spiral trajectory, thereby efficiently inducing a stable vortex state inside the pipe. This vortex state causes the water to rotate and advance closely against the pipe wall under the action of centrifugal force, which greatly reduces the frictional resistance between the fluid and the pipe wall. The low-pressure area formed at the center of the vortex can generate an additional suction effect. The synergistic effect of the two significantly reduces the resistance to the water flow and greatly accelerates the overall flow speed of the water, thereby effectively improving the drainage efficiency and throughput of the drainage pipe 1.

[0024] Working principle: During installation, precisely align the locking block 5 at the bottom of the mounting block 3 with the guide groove 2 at the top of the drain pipe 1, and press the mounting block 3 down. At this time, the locking block 5 will slide along the guide groove 2 and finally fit and lock, thus firmly installing the mounting block 3 together with the filter bag 4 at its bottom into the drain pipe 1. During the drainage process, the water generated by the refrigerator defrosting first flows into the mounting block 3, and then into the filter bag 4 below it. The filter bag 4 plays a core filtration role. Its fine pores can effectively intercept impurities and suspended particles in the water, allowing only clean water to pass through and drain into the drain pipe below. The main body of drain pipe 1 is successfully discharged. The key advantage of this design is that the filter bag 4 fundamentally prevents impurities from adhering to the inner wall of drain pipe 1, significantly reducing the risk of pipe blockage. When maintenance is required, if a large amount of impurities accumulate inside the filter bag 4, affecting the filtration efficiency, simply pull up the mounting block 3 to easily remove the mounting block 3 and filter bag 4 from the drain pipe 1 for thorough cleaning or replacement. This modular design greatly simplifies the cleaning process and significantly improves the convenience and overall efficiency of maintenance operations through circumferential distribution. The limiting strip 9, like a skeleton, effectively constrains the sidewalls of the filter bag 4, significantly suppressing the risk of excessive expansion and deformation caused by the continuous deposition and accumulation of impurities inside the filter bag 4. The bottom support ring 10, located at the bottom, acts as a supporting base, providing crucial support for the bottom of the filter bag 4. This effectively prevents the filter bag 4 from being excessively pulled downwards and breaking under the long-term effects of its own weight, water flow impact, and the weight of impurities. The two work together to ensure the structural integrity and filtration function stability of the filter bag 4 during long-term use.

[0025] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
