Description

Technical Field

[0001] The utility model relates to the field of refrigeration equipment, and particularly relates to a refrigerator for preventing ice blockage in a water guide groove. Background Art

[0002] In the field of refrigeration equipment, especially in the design of products such as refrigerators and wine cabinets, a common problem is that the temperature in the water guide groove area is relatively low due to the cold air sinking effect. Since the evaporator is often installed at a lower position due to space layout limitations and is adjacent to the water guide groove, the temperature in this area often remains below zero degree, which is extremely likely to cause the condensation water to freeze. Coupled with the surface tension of water, it makes the water easily stay on the surface of the inner tank water groove and gradually form an ice layer. More seriously, when the refrigerator defrosts, large ice blocks may fall off and fall into the drain trough. Once the drain hole is blocked, it will not only exacerbate the icing situation, but also may cause the accumulated water to overflow, affecting the normal operation of the refrigerator and the cleanliness of the surrounding environment. Content of the Utility Model

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a refrigerator for preventing ice blockage in a water guide groove.

[0004] A refrigerator for preventing ice blockage in a water guide groove includes an inner tank. An evaporator is arranged on the back plate of the inner tank. A drain trough is arranged below the evaporator, and a drain hole is opened in the drain trough.

[0005] A flow guide plate is arranged on the drain trough. The flow guide plate is provided with grid protrusions and a plurality of first ridges. The grid protrusions are located above the drain hole, and the plurality of first ridges extend towards the direction of the drain hole.

[0006] Further specifically, in the above technical solution, a hydrophobic film is arranged on the surface of the flow guide plate.

[0007] Further specifically, in the above technical solution, the inner walls of the drain trough are all inclined towards the direction of the drain hole.

[0008] Further specifically, in the above technical solution, the flow guide plate includes a flat plate and two inclined plates. The flat plate is arranged above the drain hole, the grid protrusions are arranged on the flat plate, and the two inclined plates are symmetrically arranged on both sides of the flat plate, and the inclined plates are attached to the inner walls of the drain trough.

[0009] Further specifically, in the above technical solution, the plurality of first ridges are symmetrically arranged on the two inclined plates.

[0010] Further specifically, in the above technical solution, a ice blocking plate is further arranged between the evaporator and the drain trough, and a plurality of through holes are arranged on the ice blocking plate.

[0011] More specifically, in the above technical solution, a plurality of second ridges are provided on the ice baffle.

[0015] Compared with the prior art, the embodiment of the present utility model has the following beneficial effects:

[0016] Through ingenious design, the refrigerator of the present application significantly improves the anti-icing ability of the drainage system. The grid protrusions on the diversion plate can effectively intercept ice cubes, prevent the ice cubes from directly falling into the drain hole and blocking the drainage channel.

Thus, statements such as "in one embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments" etc. that appear in different parts of this specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0028] Please refer to Figure 1-2, this application proposes a refrigerator that prevents ice blockage in the water guide groove, including an inner liner 1. An evaporator 2 is provided on the back plate of the inner liner 1, and a drain trough 3 is provided below the evaporator 2. The drain trough 3 is provided with a drain hole 4; a flow guide plate 5 is provided on the drain trough 3. The flow guide plate 5 is provided with a grid protrusion 501 and a number of first ridges 502. The grid protrusion 501 is located above the drain hole 4, and the number of the first ridges 502 extends in the direction of the drain hole 4.

[0029] Combined with the design of the grid protrusion 501 and the first ridges 502, the flow guide plate 5 forms a comprehensive anti-ice blockage system, which not only blocks the direct fall of large ice blocks and sundries to the drain hole 4, but also reduces the risk of water accumulation and ice formation by guiding the water flow.

[0030] The grid protrusion 501 is located above the drain hole 4, which can effectively prevent large ice blocks or sundries from directly falling into the drain hole 4, thus significantly reducing the risk of blockage of the drain hole 4; on the other hand, when the water flow or melted ice passes through the grid protrusion 501, it will be dispersed in multiple directions, which is beneficial to keeping the drain hole 4 unblocked.

[0031] The first ridges 502 extend in the direction of the drain hole 4, which can guide the water flow to flow more efficiently to the drain hole 4, reduce the residence time of the water flow in the drain trough 3, and reduce the possibility of water accumulation and ice formation. Moreover, through the reasonable layout of the first ridges 502 in this application, a certain water flow acceleration effect can be formed, so that the water flow forms a faster flow rate on the flow guide plate 5, further promoting drainage. In addition, the design of the ridges reduces the direct contact area between the ice block and the flow guide plate 5, which helps to accelerate the melting speed of the ice block. The reduction of the contact area means that the heat transfer efficiency is relatively improved.

[0032] In the prior art, heating wires are usually used to dissolve ice blocks. However, when the heating wires fail or the temperature in the box is set too low, the remaining water will form ice blocks, and the ice blocks will accumulate; in addition, the heating wires will also increase the cost and the difficulty of the sealing process, and at the same time increase the energy consumption.

[0033] In some embodiments, a hydrophobic film (not shown) is provided on the surface of the flow guide plate 5.

[0034] The hydrophobic film can simulate the lotus leaf effect, so that the water flow quickly forms water droplets and slides off when it touches the surface of the flow guide plate 5, reducing the residence time of water on the flow guide plate 5, thereby improving the drainage efficiency.

[0035] Preferably, the flow guide plate 5 is a metal plate. The metal plate has good compatibility with additional treatments such as the hydrophobic film, which can further improve the performance of the flow guide plate 5 and meet the special requirements during the use of the refrigerator.

[0036] Such as Figure 2As shown, in some embodiments, the inner walls of the drain trough 3 are inclined towards the direction of the drain hole 4.

[0037] The inclined inner walls can guide the water flow to flow more smoothly towards the drain hole 4, reducing the residence time of the water flow in the drain trough 3, effectively reducing the risk of accumulated water staying and freezing in the drain trough 3; and the inclined design makes it difficult for the water flow to accumulate at the bottom or side of the drain trough 3, thereby reducing the possibility of ice layer formation. Even in a low-temperature environment, the accumulated water can be quickly guided to the drain hole 4 and discharged.

[0038] As Figure 2 shown, in some embodiments, the deflector 5 includes a flat plate 503 and two inclined plates 504. The flat plate 503 is disposed above the drain hole 4, the grid protrusions 501 are disposed on the flat plate 503, the two inclined plates 504 are symmetrically disposed on both sides of the flat plate 503, and the inclined plates 504 are attached to the inner walls of the drain trough 3.

[0039] The two inclined plates 504 are symmetrically disposed on both sides of the flat plate 503 and are attached to the inner walls of the drain trough 3, enabling the water flow to flow more smoothly along the inclined plates 504 towards the drain hole 4, improving the drainage efficiency.

[0040] The combined design of the flat plate 503 and the inclined plates 504 enhances the overall structural strength of the deflector 5, making it more stable and reliable during installation and use.

[0041] As Figure 2 shown, in some embodiments, a number of the first ridges 502 are symmetrically disposed on the two inclined plates 504.

[0042] The first ridges 502 are symmetrically distributed on the two inclined plates 504 of the deflector 5, which helps to achieve uniform guidance and distribution of the water flow. By making the number and arrangement of the first ridges 502 on both sides the same, it ensures that the water flow on the deflector 5 is more stable and balanced, reducing the phenomenon of retention or accumulation caused by uneven water flow.

[0043] As Figure 1 and Figure 3 shown, in some embodiments, a baffle 6 is further disposed between the evaporator 2 and the drain trough 3, and a number of through holes 601 are disposed on the baffle 6.

[0044] The main function of the baffle 6 is to prevent the large ice blocks formed on the evaporator 2 from directly falling into the drain trough 3 and generating abnormal noises, and to prevent the drain hole 4 from being blocked by the large ice blocks. It is crucial to keep the drainage system of the refrigerator unobstructed, extending the service life of the refrigerator and improving its operating efficiency.

[0045] As Figure 3As shown, in some embodiments, a plurality of second ridges 602 are provided on the ice baffle 6.

[0046] The design of the second ridges 602 can also reduce the attachment area of ice on the ice baffle 6. When ice attempts to form on the ice baffle 6, the gaps between the second ridges 602 will disrupt the continuity of the ice, making it more difficult for the ice to firmly adhere to the ice baffle 6 and reducing the accumulation and retention of ice on the ice baffle 6.

[0047] As Figure 3 shown, in some embodiments, a plurality of the second ridges 602 are arranged in parallel.

[0048] The second ridges 602 arranged in parallel can more effectively guide the water flow along a predetermined path. The gaps between them provide clear channels for the water flow, reducing the disordered diffusion and accumulation of the water flow on the ice baffle 6, thereby improving the drainage efficiency.

[0049] As Figure 4 shown, in some embodiments, a plurality of the second ridges 602 are all of hollow structures.

[0050] Adopting the hollow structure design can significantly reduce the amount of material used, which conforms to the design concept of environmental protection. At the same time, this also reduces the production cost and improves the cost performance of the product.

[0051] As Figure 3 shown, in some embodiments, on the side of the ice baffle 6 close to the back plate of the inner container 1, a mounting plate 603 is provided. A plurality of mounting holes 6031 are provided on the mounting plate 603. The ice baffle 6 is fixedly connected to the back plate of the inner container 1 through a fixing member passing through the mounting holes 6031. The fixing member can be a screw or the like.

[0052] Through the combined use of the mounting plate 603 and the fixing member, it is ensured that the ice baffle 6 can be firmly fixed on the back plate of the inner container 1, effectively preventing the ice baffle 6 from loosening or falling off during use, thus ensuring its long-term reliability and durability.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be included in the protection scope of the present invention.
