[0002] When the air-cooled refrigerator is opened or closed, a large amount of condensed water will be generated on the air duct surface. If this condensed water is not discharged to the refrigerator water tray and then to the evaporation tray outside the refrigerator, it will flow into the refrigerator body and form ice cubes, affecting the normal use of the refrigerator.
[0003] Therefore, when designing the air duct, it is necessary to design a drain port on its surface. However, when designing the drain port, there are the following problems: if the drain port is designed to be small, the condensed water on the surface will overflow and flow into the refrigerator; if the drain port is designed to be large, during the safety test, the test finger can easily be inserted into the hole and touch the heater, and safety cannot be guaranteed.

[0022] Embodiment 1
[0023] See also Figure 1 As shown, this embodiment is a duct drain structure, including a duct cover plate 1, a larger-sized drain port 2 is provided at the bottom of the duct cover plate 1, and the size of the drain port 2 is specifically set according to the size of the duct cover plate 1. The larger-sized drain port 2 can prevent the condensed water on the surface of the duct cover plate 1 from overflowing from the drain port 2 and flowing into the refrigerator box. The drain port 2 is connected to water guide ribs 3 integrally provided with the duct cover plate 1 on both sides, and the angle between the water guide ribs 3 and the horizontal plane at the bottom of the duct cover plate 1 is 8°-10°, and the angle is preferably 8°. The setting of the water guide ribs 3 ensures that all the condensed water on the surface of the duct cover plate 1 can flow into the larger-sized drain port 2, and the water guide ribs 3 are inclined at a small angle, which can not only guide all the condensed water on the surface of the duct cover plate 1 to flow into the larger-sized drain port 2, but also prevent the flow rate of the condensed water from being too fast.
[0024] However, due to the large size of the drain port 2, the test finger can easily be inserted into the hole during the safety test and touch the heater. Safety cannot be guaranteed and the refrigerator cannot be produced. Safety test, also known as safety specification test, is a very important part of the development and production process of electrical products. It aims to ensure that the product meets national and international safety standards, thereby protecting users from potential harm and improving the market competitiveness of the product.
[0025] Therefore, please refer to Figure 2 and Figure 3As shown, the present application sets a protective rib 4 in the drain outlet 2. The protective rib 4 includes a transverse rib 41 and a vertical rib 42. The transverse rib 41 is parallel to the air duct cover plate 1. The transverse rib 41 can be the same size as the outer side of the drain outlet 2. The transverse rib 41 is drafted to both sides and is connected to the outer side surfaces of the two water-guiding ribs 3 to increase the drainage hole area and increase the water flow rate. The vertical rib 42 is integrally formed on the inner side of the transverse rib 41, and the vertical rib 42 is perpendicular to the center line of the transverse rib 41. The vertical rib 42 is located in the drain outlet 2. Preferably, the upper and lower ends of the vertical rib 42 are fixedly connected to the upper and lower ends of the drain outlet 2 respectively, and the vertical rib 42 and the transverse rib 41 form a T-shaped structure. The protective rib 4 of the T-shaped structure is added to the drain outlet 2. The protective rib 4 not only strengthens the strength of the drain outlet 2 of the air duct cover plate 1, so that the test finger cannot pass through, ensuring safety, but also does not affect the normal demolding of the product and increase the mold cost.
[0026] Embodiment 2
[0027] See also Figure 4 As shown, this embodiment provides a refrigerator, in which the air duct drain port 2 structure of the first embodiment is fixedly installed in the freezer box 5 of the refrigerator. A water receiving pan 6, a water guide pipe 7 and an evaporation pan 8 are also provided at the bottom of the refrigerator, the drain port 2 is connected to the water receiving pan 6, and the water receiving pan 6 is connected to the evaporation pan 8 through the water guide pipe 7.
[0028] When the refrigerator door is opened or closed, a large amount of condensed water generated on the surface of the air duct cover 1 is guided by two water guide ribs 3. All the condensed water on the surface of the air duct cover 1 can flow into the larger drain port 2. The condensed water then flows from the drain port 2 into the water receiving tray 6. Finally, the condensed water in the water receiving tray 6 is finally discharged to the evaporation tray 8 at the bottom of the refrigerator through the water guide pipe 7.
[0029] In summary, the utility model provides a duct drain port 2 structure and a refrigerator having the same. Due to the provision of a larger-sized drain port 2 and water-guiding ribs 3 located on both sides of the drain port 2, all condensed water on the surface of the duct cover plate 1 can flow into the larger-sized drain port 2, thereby preventing condensed water on the surface of the duct cover plate 1 from overflowing from the drain port 2 into the refrigerator box. At the same time, due to the provision of a T-shaped protective rib 4 at the drain port 2, the protective rib 4 not only strengthens the strength of the drain port 2 of the duct cover plate 1, preventing the test finger from passing through, thereby ensuring safety, but also does not affect the normal demolding of the product and increase the mold cost.
[0030] The above detailed description of the preferred embodiments of the utility model should not be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
