Technical Field

[0001] This disclosure relates to the field of refrigerator technology, specifically to an air duct cover and a refrigerator. Background Technology

[0002] In related technologies, refrigerators are equipped with air duct covers. After the fan blows cold air into the air ducts inside the air duct cover, the cold air is blown into the refrigerator's storage compartment through the air outlets of the air ducts. Currently, the uniformity of airflow from the air outlets is poor, which results in poor airflow performance from the air duct cover. Utility Model Content

[0003] The purpose of this disclosure is to provide a duct cover that has a better air outlet effect.

[0004] To achieve the above objectives, this disclosure provides a duct cover plate, which is provided with an air outlet and an air guide structure. The air outlet has a center line extending along its own air outlet direction. The air guide structure includes at least one air guide surface, which is inclined and its downstream end is closer to the center line than its upstream end.

[0005] Optionally, at least one air guiding surface includes a first air guiding surface, and the duct cover includes a first sidewall and a second sidewall disposed opposite to each other, the first sidewall and the second sidewall being used to form the air outlet, and at least one of the first sidewall and the second sidewall having the first air guiding surface.

[0006] Optionally, the duct cover has a fan mounting portion, the first sidewall is closer to the fan mounting portion than the second sidewall, and the first sidewall has the first air guiding surface.

[0007] Optionally, the angle between the first air guide surface and the center line is 3° to 7°.

[0008] Optionally, at least one air guiding surface includes a second air guiding surface, and the air guiding structure includes at least one first air guiding plate. The first air guiding plate is disposed in the air outlet, and the first air guiding plate is inclined and has a second air guiding surface disposed on both opposite sides of itself.

[0009] Optionally, the air guiding structure includes two first air guiding plates, which are respectively disposed on both sides of the center line.

[0010] Optionally, the air guiding structure includes a second air guiding plate, which is disposed between the two first air guiding plates and coincides with the center line.

[0011] Optionally, the first air guide plate has a length in its own inclined direction, and the second air guide plate has a length in the extension direction of the center line;

[0012] The first air guide plate near the first sidewall is constructed as the first plate, and the first air guide plate away from the first sidewall is constructed as the second plate. The lengths of the first plate, the second air guide plate, and the second plate increase sequentially.

[0013] Optionally, the first air guide plate near the first sidewall is configured as a first plate, and the first air guide plate away from the first sidewall is configured as a second plate, with the upstream end of the first plate located downstream of the upstream end of the second air guide plate, and the upstream end of the second air guide plate located downstream of the upstream end of the second plate.

[0014] Optionally, the first air guide plate near the first sidewall is constructed as a first plate, and the first air guide plate away from the first sidewall is constructed as a second plate, with the downstream ends of the first plate, the downstream ends of the second air guide plate, and the downstream ends of the second plate being flush.

[0018] Optionally, the refrigerator includes a freezer compartment, and the air duct cover is used to supply cold air to the freezer compartment.

[0019] Through the above technical solution, in the duct cover provided in this disclosure, by setting an air guide structure at the air outlet, the airflow flowing out of the air outlet can be guided by the air guide structure. In this case, since the air guide surface is set at an inclination and its downstream end is closer to the center line than its upstream end, the air guide surface can guide part of the airflow to the part of the air outlet near the center line. That is, the air guide surface can guide part of the airflow to the middle of the air outlet. In this way, the airflow velocity or flow rate at the air guide surface can be avoided, as well as the airflow velocity or flow rate in the middle of the air outlet can be avoided. Thus, the airflow velocity or flow rate at various parts of the air outlet can be balanced, thereby improving the uniformity of the air outlet and improving the air outlet effect of the duct cover.

Detailed Implementation

[0029] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0030] In this disclosure, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are defined based on the direction of gravity of the duct cover, where "upper" corresponds to "top," and "lower" corresponds to "bottom." The vertical direction can be referenced... Figure 1 The drawing orientation. "Inner" and "outer" refer to the inner and outer contours of each component itself. The terms "first" and "second" are used to distinguish one element from another and do not have sequential or importance. Furthermore, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings indicate the same or similar elements, which will not be repeated in this comparative disclosure.

[0031] According to some embodiments of this disclosure, a duct cover 100 is provided, with reference to... Figures 1 to 4 As shown, the duct cover 100 is provided with an air outlet 1, and an air guide structure 2 is provided at the air outlet 1. The air outlet 1 has a center line 11 extending along its own air outlet direction. The air guide structure 2 includes at least one air guide surface 21. The air guide surface 21 is inclined and its downstream end is closer to the center line 11 than its upstream end.

[0032] Through the above technical solution, in the duct cover 100 provided in this disclosure, by setting an air guide structure 2 at the air outlet 1, the airflow flowing out of the air outlet 1 can be guided by the air guide structure 2. Since the air guide surface 21 is set at an inclination and its downstream end is closer to the center line 11 than its upstream end, the air guide surface 21 can guide part of the airflow to the part of the air outlet 1 located near the center line 11. That is, the air guide surface 21 can guide part of the airflow to the middle of the air outlet 1. In this way, the airflow velocity or flow rate at the air guide surface 21 can be avoided from being too high, and the airflow velocity or flow rate in the middle of the air outlet 1 can be avoided from being too low. Thus, the airflow velocity or flow rate at each part of the air outlet 1 can be balanced, thereby improving the uniformity of the airflow from the air outlet 1 and improving the air outlet effect of the duct cover 100.

[0033] It should be noted that the air outlet direction of air outlet 1 can be referenced to the orientation of air outlet 1, and the centerline 11 of air outlet 1 refers to the line that passes through the geometric center of air outlet 1 and extends along the air outlet direction. In some embodiments, reference... Figures 1 to 4 As shown, the air outlet 1 can be opened along the thickness direction of the air duct cover 100, and this disclosure does not limit this.

[0034] In some embodiments of this disclosure, reference is made to Figures 1 to 4 As shown, at least one air guiding surface 21 may include a first air guiding surface 211, and the duct cover 100 may include a first sidewall 3 and a second sidewall 4 disposed opposite to each other, the first sidewall 3 and the second sidewall 4 forming an air outlet 1, and at least one of the first sidewall 3 and the second sidewall 4 having a first air guiding surface 211. Here, refer to Figure 2 As shown, the duct cover 100 may have multiple sidewalls that form an air outlet 1. The multiple sidewalls are connected in sequence to form an air outlet 1. Among the multiple sidewalls, there are first sidewalls 3 and second sidewalls 4 arranged opposite to each other. At least one of the first sidewalls 3 and second sidewalls 4 is provided with the aforementioned first air guide surface 211. The advantage of this arrangement is that since the first sidewalls 3 and second sidewalls 4 are used to form an air outlet 1, the first sidewalls 3 and second sidewalls 4 are relatively far away from the center line 11 of the air outlet 1. That is, the airflow velocity or flow rate at the first sidewalls 3 and second sidewalls 4 is relatively large. Therefore, by providing the first air guide surface 211 on the first sidewalls 3 and / or the second sidewalls 4, the airflow velocity or flow rate at each point of the air outlet 1 can be further balanced, thereby further improving the uniformity of the air outlet 1.

[0035] In some embodiments of this disclosure, reference is made to Figure 3 and Figure 4As shown, the duct cover 100 may have a fan mounting portion 5. The first sidewall 3 is closer to the fan mounting portion 5 than the second sidewall 4, and the first sidewall 3 has a first air guide surface 211. Here, since the first sidewall 3 is closer to the fan mounting portion 5, its position is closer to the fan, resulting in a higher airflow velocity at the first sidewall 3. Therefore, by providing the first air guide surface 211 at the first sidewall 3, more airflow can be directed to the center of the air outlet 1, thereby further improving the uniformity of airflow from the air outlet 1. Furthermore, since the first sidewall 3 is closer to the fan, providing the first air guide surface 211 at the first sidewall 3 also allows more airflow to exit from the air outlet 1, thereby increasing the airflow volume of the air outlet 1, increasing the average airflow velocity of the air outlet 1, and improving the refrigeration or freezing effect of the duct cover 100.

[0036] Of course, in other embodiments, the first sidewall 3 and the second sidewall 4 may also be arranged on the upper and lower sides of the air duct cover 100, and this disclosure does not limit this.

[0037] In some implementations, reference Figure 4 and Figure 5 As shown, the angle between the first air guide surface 211 and the center line 11 can be 3° to 7°, for example, 5°. This can effectively improve the uniformity of airflow when the angle is too small, and can also prevent turbulence from being generated when the angle is too large.

[0038] In some embodiments of this disclosure, reference is made to Figure 2 and Figure 4 As shown, at least one air guiding surface 21 may include a second air guiding surface 212, and the air guiding structure 2 may include at least one first air guiding plate 22. The first air guiding plate 22 is disposed in the air outlet 1, wherein the first air guiding plate 22 is inclined and has second air guiding surfaces 212 disposed on both opposite sides of itself. Here, the first air guiding plate 22 may be distinguished from the sidewalls used to form the air outlet 1, and the first air guiding plate 22 is disposed in the air outlet 1. By inclinedly disposing the first air guiding plate 22 and having second air guiding surfaces 212 disposed on both opposite sides of itself, the first air guiding plate 22 can guide the airflow passing through it to the center of the air outlet 1, thereby improving the uniformity of the airflow from the air outlet 1.

[0039] In some embodiments of this disclosure, reference is made to Figure 4 As shown, the air guiding structure 2 may include two first air guiding plates 22, which may be respectively disposed on both sides of the center line 11. In this way, the uniformity of airflow on both sides of the center line can be improved.

[0040] In some implementations, reference Figure 2 and Figure 4As shown, the air guiding structure 2 may include a second air guiding plate 23. The second air guiding plate 23 is disposed between the two first air guiding plates 22 and coincides with the center line 11. That is, the second air guiding plate 23 extends in the same direction as the center line 11, and the projection of the center line 11 falls on the second air guiding plate 23. The advantage of this arrangement is that by using the extension of the second air guiding plate 23 along the center line 11, the airflow in the middle of the air outlet 1 can be turned as it gradually flows out, thereby facilitating the flow of more airflow in the air outlet direction.

[0041] In some embodiments, reference Figure 4 As shown, the first guide plate 22 has a length in its own inclined direction, and the second guide plate 23 has a length in the extension direction of the centerline 11. The first guide plate 22 closer to the first sidewall 3 is constructed as a first plate 10, and the first guide plate 22 farther from the first sidewall 3 is constructed as a second plate 20. The lengths of the first plate 10, the second guide plate 23, and the second plate 20 increase sequentially. Thus, since the first plate 10, the second guide plate 23, and the second plate 20 are successively farther from the fan, increasing their lengths sequentially prolongs the time the airflow stays on each plate. This allows the airflow further away from the fan to be guided for a longer period, thereby further improving the uniformity of the airflow.

[0042] In some embodiments, reference Figure 4 As shown, the first air guide plate 22 near the first sidewall 3 is configured as a first plate 10, and the first air guide plate 22 away from the first sidewall 3 is configured as a second plate 20. The upstream end of the first plate 10 is located downstream of the upstream end of the second air guide plate 23, and the upstream end of the second air guide plate 23 is located downstream of the upstream end of the second plate 20. In this way, since the first plate 10, the second air guide plate 23, and the second plate 20 are successively away from the fan, the airflow further away from the fan can be guided earlier, thereby further improving the uniformity of the airflow.

[0043] In some embodiments, reference Figure 4 As shown, the first air guide plate 22 near the first sidewall 3 is constructed as a first plate 10, and the first air guide plate 22 away from the first sidewall 3 is constructed as a second plate 20. The downstream ends of the first plate 10, the second air guide plate 23, and the second plate 20 are flush. In this way, the airflow time through the first plate 10, the second air guide plate 23, and the second plate 20 and out of the air outlet 1 is basically the same, thereby further improving the uniformity of the airflow.

[0044] In some embodiments, reference Figure 4 and Figure 5As shown, the angle between the second air guide surface 212 and the center line 11 can be 8° to 12°, for example, it can be 10°, and this disclosure does not limit it.

[0045] In some embodiments of this disclosure, reference is made to Figure 1 and Figure 3 As shown, the duct cover 100 may have a fan mounting portion 5, and the air outlet 1 may be set higher than the fan mounting portion 5. Here, because the air outlet 1 is set higher and its position is offset from the fan, the airflow from the fan will be significantly deflected when it reaches the air outlet 1. Therefore, by providing the aforementioned air guiding structure 2 and air guiding surface 21 at the air outlet 1, it is beneficial to optimize the uniformity of the airflow at the air outlet 1. In some embodiments, at least two air outlets 1 may be provided, each air outlet 1 may be set higher than the fan mounting portion 5, and each air outlet 1 may be provided with the aforementioned air guiding structure 2. This disclosure does not impose any limitations on this.

[0046] According to a second aspect of this disclosure, a refrigerator is provided, including the air duct cover 100 as described above. This refrigerator has all the beneficial effects of the air duct cover 100 described above, which will not be elaborated upon here.

[0047] In some embodiments of this disclosure, the refrigerator may include a freezer compartment, and the air duct cover 100 may supply cold air to the freezer compartment. Of course, in other embodiments, the refrigerator may also include a refrigerator compartment, and the aforementioned air duct cover 100 may also supply cold air to the refrigerator compartment; this disclosure does not limit this. Of course, in other embodiments, the refrigerator may also include a variable temperature compartment, and the aforementioned air duct cover 100 may also supply cold air to the variable temperature compartment; this disclosure does not limit this.

[0048] In some embodiments, one side of the refrigerator door can be the front side, and the air outlet 1 can be arranged facing forward so as to blow cold air into the refrigerator compartment, freezer compartment or variable temperature compartment.

[0049] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0050] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.
