A drip tray is usually located at the bottom of the evaporator to collect the liquid water formed by the melting frost. The drip tray has a drain outlet through which the water drains out.
[0003] However, if there is residual ice in the drip tray, it can cause blockage of the drain, leading to problems such as water overflowing from the drip tray. Utility Model Content
[0004] This application provides a drip tray, a heating component, and a refrigerator to solve the problem of ice blockage at the drain outlet of the drip tray in existing refrigerators.

[0006] A disc body is positioned below the first tube body along the direction of gravity, and the disc body is provided with a drain outlet;

[0008] Optionally, the heat-conducting rib includes a heat-conducting surface near the first tube body, and the heat-conducting surface is conformally matched to the corresponding first tube body.

[0011] The heating element includes a first tube body and a second tube body. The first tube body is disposed below the evaporator along the direction of gravity, and the second tube body is disposed around the periphery of the evaporator.
[0012] As described above, the water receiving tray includes:
[0013] A disc body is positioned below the first tube body along the direction of gravity, and the disc body is provided with a drain outlet;
[0014] The heat-conducting rib has two ends connected to the disc body and located on opposite sides of the drain outlet. In the direction of gravity, the heat-conducting rib arches upwards towards the drain outlet and is adjacent to the first pipe body.
[0015] Optionally, it further includes a first heat-conducting sheet, which extends from the first tube body to the drain outlet, and the orthographic projection of the first heat-conducting sheet on the disc body is distributed at intervals with the heat-conducting ribs.
[0016] Optionally, in the horizontal direction, the projection of the first heat-conducting sheet falls at least partially on the heat-conducting rib.

[0025] The water receiving tray provided in this embodiment is adjacent to the first tube of the heating pipe. A heat-conducting rib is provided around the drain outlet of the tray. This rib arches between the drain outlet and the first tube, transferring heat from the first tube to the portion around the drain outlet on the tray for defrosting or de-icing. Simultaneously, since the connection points between the two ends of the heat-conducting rib and the tray are located on opposite sides of the drain outlet, an arched heat-conducting space is formed above the drain outlet. This reduces heat loss from the heat-conducting space, improving the heat conduction effect of the rib and allowing direct heating of the drain outlet to prevent ice blockage. Compared to a connection method where one end of the heat-conducting rib is connected to the tray and the other end to the first tube, the heat-conducting rib in this application loses less heat and has a better heat conduction effect.

[0045] This application provides a drip tray, a heating assembly, and a refrigerator to solve the problem of ice blockage at the drain outlet of the drip tray in existing refrigerators. The following description is in conjunction with the accompanying drawings.
[0046] The drip tray provided in this embodiment is used in a refrigerator, which includes an evaporator 3 and a heating element 2. Please refer to [link / reference]. Figure 3 , Figure 3 This is a schematic diagram of the water receiving tray provided in an embodiment of this application. The heating tube 2 includes a first tube body 21, which is disposed below the evaporator 3 along the direction of gravity. The water receiving tray includes a tray body 1 and heat-conducting ribs 12. The tray body 1 is disposed below the first tube body 21 along the direction of gravity and has a drain outlet 11. Both ends of the heat-conducting ribs 12 are connected to the tray body 1 and are located on opposite sides of the drain outlet 11. In the direction of gravity, the heat-conducting ribs 12 arch upwards towards the drain outlet 11 and are adjacent to the first tube body 21.
[0047] The water receiving tray provided in this embodiment has a tray body 1 adjacent to the first tube body 21 of the heating pipe 2. A heat-conducting rib 12 is provided around the drain outlet 11 of the tray body 1. The heat-conducting rib 12 arches between the drain outlet 11 and the first tube body 21, conducting heat from the first tube body 21 to the portion around the drain outlet 11 on the tray body 1 for defrosting or de-icing. Simultaneously, since the connection points of the two ends of the heat-conducting rib 12 to the tray body 1 are located on opposite sides of the drain outlet 11, the heat-conducting rib 12 forms an arched heat-conducting space above the drain outlet 11, reducing heat loss from the heat-conducting space and improving the heat conduction effect of the heat-conducting rib 12. It also allows direct heating of the drain outlet 11, preventing ice blockage. Compared to a connection method where one end of the heat-conducting rib 12 is connected to the tray body 1 and the other end to the first tube body 21, the heat loss from the heat-conducting rib 12 in this application is less, resulting in better heat conduction. Furthermore, the water tray has a simple structure and can defrost or defrost the drain outlet 11 without the need for an additional heat source, thus improving the heat utilization rate of the heating element 2. Finally, the heat-conducting rib 12 arches upwards towards the drain outlet 11, which will not affect the drainage effect at the drain outlet 11 and ensures smooth drainage.
[0048] Due to human installation factors, the installation distance between the water receiving tray 1 and the first pipe 21 is usually uncontrollable. Therefore, the heat-conducting rib 12 is set to be adjacent to the first pipe 21, thereby reducing the installation requirements of the water receiving tray and saving installation time.
[0049] Preferably, the heat-conducting rib 12 can also be configured to abut against the first tube body 21 to improve heat transfer efficiency. Of course, this connection method has higher installation requirements for the water pan.
[0050] Optionally, the heat-conducting rib 12 includes a heat-conducting surface 121 close to the first tube body 21, and the heat-conducting surface 121 is conformally matched with the corresponding first tube body 21. By conformally matching the heat-conducting surface 121 with the corresponding first tube body 21, the heat-conducting surface area 121 between the heat-conducting rib 12 and the first tube body 21 is maximized, thereby improving the heat conduction capability of the heat-conducting rib 12.
[0051] In some examples, the portion of the first tube 21 corresponding to the heat-conducting surface 121 is cylindrical. In this case, the heat-conducting surface 121 is an arc surface, and the cylinder corresponding to the arc-shaped heat-conducting surface 121 is coaxial with the cylindrical first tube 21.
[0052] In other examples, the portion of the first tube 21 corresponding to the heat-conducting surface 121 is rectangular columnar. In this case, the heat-conducting surface 121 is planar and parallel to the surface of the adjacent rectangular columnar first tube 21.
[0053] Optionally, the extension direction of the heat-conducting rib 12 is the same as the extension direction of the first tube body 21. By extending the heat-conducting rib 12 in the same direction as the first tube body 21, the heat-conducting surface area 121 of the heat-conducting rib 12 relative to the first tube body 21 is further increased, thereby improving the ability of the heat-conducting rib 12 to defrost or defrost at the drain outlet 11.
[0054] This application also provides a heating assembly for use in a refrigerator. The refrigerator includes an evaporator 3, and the heating assembly includes a heating element 2 and a drip tray as described above. Please refer to... Figures 1 to 5 The heating tube 2 includes a first tube body 21 and a second tube body 22. The first tube body 21 is disposed below the evaporator 3 along the direction of gravity, and the second tube body 22 is disposed around the periphery of the evaporator 3. The water receiving tray includes a tray body 1 and heat-conducting ribs 12. The tray body 1 is disposed below the first tube body 21 along the direction of gravity, and the tray body 1 is provided with a drain outlet 11. Both ends of the heat-conducting ribs 12 are connected to the tray body 1 and are respectively located on opposite sides of the drain outlet 11. In the direction of gravity, the heat-conducting ribs 12 arch upwards at least partially towards the drain outlet 11 and are adjacent to the first tube body 21.
[0055] The heating tube 2 includes both a second tube body 22 to achieve the defrosting effect on the evaporator 3 and a first tube body 21 to defrost or defrost the water tray. It does not require an additional heat source to achieve the defrosting or defrosting function at the drain outlet 11 of the water tray, saving energy, and the overall structure of the heating component is simple.
[0056] The number of the first tube 21 and the second tube 22 is not further limited here; both can include multiple tubes, or the second tube 22 can include multiple tubes while the first tube 21 can include only one tube. The position of the second tube 22 is also not further limited. In some examples, the second tube 22 includes multiple tubes, which are spaced apart on one side of the evaporator 3; in other examples, the second tube 22 includes multiple tubes, with some spaced apart on one side of the evaporator 3 and some spaced apart on the other side; in still other examples, the second tube 22 includes multiple tubes, with some spaced apart on one side of the evaporator 3 and some spaced apart at the bottom of the evaporator 3, above the first tube 21.
[0057] Optionally, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 , Figure 1 This is a schematic diagram of the heating tube of the heating assembly provided in an embodiment of this application. Figure 2 for Figure 1 A magnified view of a portion of point A in the middle. Figure 4 This is a schematic diagram illustrating the installation of the heating element and water receiving tray of the heating assembly provided in an embodiment of this application. Figure 5 for Figure 4 A magnified view of a section at point B. Figure 6 This is a schematic diagram of the installation of the evaporator and heating assembly of a refrigerator provided in an embodiment of this application. The heating assembly provided in this embodiment of the application further includes a first heat-conducting plate 211, which extends from the first tube 21 to the drain outlet 11. The orthographic projection of the first heat-conducting plate 211 on the plate 1 is spaced apart from the heat-conducting ribs 12. That is, the first heat-conducting plate 211 and the heat-conducting ribs 12 are staggered, which not only avoids interference with the heat-conducting ribs 12, but also makes up for the space above the drain outlet 11 where no heat-conducting ribs 12 are provided. Without blocking the drain outlet 11, it further increases the temperature at the drain outlet 11 and avoids ice blockage at the drain outlet 11.
[0058] Optionally, in the horizontal direction, the projection of the first heat-conducting sheet 211 at least partially falls on the heat-conducting rib 12. That is, in the horizontal direction, the first heat-conducting sheet 211 and the heat-conducting rib 12 are at least partially adjacent, so that the heat in the space between the adjacent portion of the first heat-conducting sheet 211 and the heat-conducting rib 12 is higher, further increasing the temperature at the drain outlet 11.
[0059] The length of the first heat-conducting plate 211 is not further limited here. In some examples, the length of the first heat-conducting plate 211 is equal to the distance between the first tube 21 and the drain outlet 11; in other examples, the length of the first heat-conducting plate 211 is greater than the distance between the first tube 21 and the drain outlet 11, that is, the first heat-conducting plate 211 passes through the drain outlet 11 or even is below the water receiving tray; in still other examples, the length of the first heat-conducting plate 211 is less than the distance between the first tube 21 and the drain outlet 11.
[0060] Optionally, please refer to Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of another structure of the heating tube of the heating assembly provided in an embodiment of this application. Figure 8 for Figure 7 The enlarged view at point C shows that the heating assembly provided in this embodiment further includes a second heat-conducting plate 212. The second heat-conducting plate 212 extends from the first tube 21 towards the drain outlet 11. In the direction of gravity, the second heat-conducting plate 212 is opposite to and spaced apart from the heat-conducting rib 12. The second heat-conducting plate 212 improves the heat conduction efficiency between the first tube 21 and the heat-conducting rib 12. It is understood that the sum of the length of the second heat-conducting plate 212 and the height of the heat-conducting rib 12 is less than or equal to the distance between the first tube 21 and the disc 1, so as to avoid interference between the second heat-conducting plate 212 and the heat-conducting rib 12.
[0061] Optionally, multiple first heat-conducting plates 211 and multiple second heat-conducting plates 212 are included, and the multiple first heat-conducting plates 211 and multiple second heat-conducting plates 212 are spaced apart on the side of the first tube 21 facing the disk 1. The sum of the spacing between the multiple second heat-conducting plates 212 can be greater than or equal to the length of the heat-conducting rib 12.
[0062] Optionally, the first heat-conducting plate 211 and the second heat-conducting plate 212 are both integrally formed with the first tube body 21; and / or, the heat-conducting rib 12 is integrally formed with the disc body 1. In one specific embodiment, the first heat-conducting plate 211 and the second heat-conducting plate 212 are both integrally formed with the first tube body 21; in another specific embodiment, the first heat-conducting plate 211 and the second heat-conducting plate 212 are both integrally formed with the first tube body 21, and the heat-conducting rib 12 is integrally formed with the disc body 1; in yet another specific embodiment, the heat-conducting rib 12 is integrally formed with the disc body 1.
[0063] Specifically, the heat-conducting rib 12 can be stamped from the disc body 1. Alternatively, the heat-conducting rib 12 can be welded to the disc body 1. Furthermore, the disc body 1 includes a sidewall surrounding a drain outlet 11, and the two ends of the heat-conducting rib 12 are connected to the sidewall.
[0064] Specifically, the first heat-conducting plate 211 and the second heat-conducting plate 212 can be formed by shaving the wall of the first tube 21. This not only reduces the wall thickness of the corresponding first tube 21 and increases the heating effect of the first tube 21 at the drain outlet 11, but also simplifies the production method of the first heat-conducting plate 211 and the second heat-conducting plate 212, eliminating the need for additional splicing of the first heat-conducting plate 211 and the second heat-conducting plate 212. The length of the first heat-conducting plate 211 and the second heat-conducting plate 212 can be controlled by controlling the distance of shaving.
[0065] Optionally, the heat-conducting rib 12, the first heat-conducting sheet 211, and the second heat-conducting sheet 212 are all made of metal to facilitate heat conduction.
[0066] This application also provides a refrigerator, including an evaporator 3 and a drip tray as described above. Alternatively, it may include an evaporator 3 and a heating assembly as described above.
[0067] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
