Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, and in particular to a refrigerator. Background Art

[0002] A freezer is a household or commercial appliance used to refrigerate or freeze food and items. It usually uses refrigeration technology to keep the temperature at a lower level to keep the food fresh and extend its shelf life.

[0003] In the prior art, a refrigerator comprises a box body, an evaporator is arranged inside the box body, an air duct is arranged inside the box body, and an air port connected to the air duct is opened on the inner side wall of the box body, so that cold air from the evaporator enters the box body through the air duct and the air port.

[0004] However, in the prior art, the air supply efficiency of ordinary air supply vents is relatively low. During the cooling process of the freezer, the air supply efficiency directly affects the cooling speed and efficiency. An inefficient air supply system means that the cold air is unevenly distributed, resulting in higher temperatures in some areas inside the freezer than in other areas. This uneven temperature distribution not only affects the quality of stored items, especially for perishable foods, but may also lead to energy waste because the freezer takes longer to reach the set temperature. Secondly, the slow cooling speed caused by the design of ordinary air supply vents is another important issue. Against the background of the growing demand for rapid cooling, traditional air supply designs cannot meet the market demand for rapid cooling. Especially in commercial environments, rapid cooling is not only related to the quality of food preservation, but also to operational efficiency and energy costs. Utility Model Content

[0137] In some embodiments, the side of the refrigerator air outlet 996 away from the interior of the box 100 is wider, and gradually narrows toward the side close to the interior of the box 100. This tapering shape can be linear, that is, gradually decreasing at a constant angle; or non-linear, such as a curved shape, designed according to specific airflow dynamics principles.

[0138] In some embodiments, the tapered refrigerator air outlet 996 is implemented in an embedded manner, that is, the internal structure of the refrigerator air outlet 996 gradually becomes narrower.

[0139] In some embodiments, the tapered refrigerator air outlet 996 is implemented in an outward convex form, that is, the outward convex form is that the outer shape of the refrigerator air outlet 996 is convex to form a gradually shrinking channel.

[0140] In some embodiments, the tapered refrigerator air outlet 996 is implemented in an integrally formed manner, that is, the refrigerator air outlet 996 is an integral component that gradually shrinks from one end to the other end.

[0141] It is worth noting that the inner wall of the flange 997 and the inner wall of the refrigerator air outlet 996 are smoothly transitioned to avoid affecting the air flow output.

[0142] In some embodiments, the diameter of the vents gradually decreases along the direction of the airflow output through the refrigerator air outlet 996. By utilizing the nozzle effect, the airflow velocity is increased by reducing the diameter of the vents, which helps to improve the airflow power and refrigeration efficiency in the refrigerator, and is also conducive to the uniform distribution of the airflow.

[0143] In some embodiments, the interior shape of the ventilation hole is nozzle-shaped.

[0144] In some embodiments, the interior shape of the vent is funnel-shaped.

[0145] In some embodiments, the vent is wider on the side facing the corresponding refrigerator air outlet 996 and gradually narrows on the side away from the corresponding refrigerator air outlet 996. This tapering shape can be linear, that is, gradually decreasing at a constant angle; or non-linear, such as a curved shape, designed according to specific airflow dynamics principles.

[0146] In some embodiments, the tapered ventilation hole is implemented in an embedded manner, that is, the internal structure of the ventilation hole gradually becomes narrower.

[0147] In some embodiments, the tapered ventilation hole is implemented in an outward convex form, that is, the outward convex form is a convex outer shape of the ventilation hole, forming a gradually shrinking channel.

[0148] In some embodiments, the tapered ventilation hole is implemented as an integrally formed type, that is, the ventilation hole is an integral component, gradually shrinking from one end to the other end.

[0149] In some embodiments, the cross-sectional area of ​​the refrigerator air outlet 996 is smaller than the cross-sectional area of ​​the ventilation hole. This helps to form a higher air flow velocity at the refrigerator air outlet 996, promotes air flow circulation in the refrigerator through differential speed, thereby enhancing the refrigeration effect and improving temperature uniformity. In addition, because the air inside the refrigerator will pass through the ventilation hole together with the air flow output through the refrigerator air outlet 996 under Bernoulli's principle, the air volume passing through the ventilation hole must be greater than the air volume passing through the refrigerator air outlet 996, so the space of the ventilation hole is greater than the aperture of the refrigerator air outlet 996.

[0150] In some embodiments, the cross-sectional shape of the refrigerator air outlet 996 is the same as the cross-sectional shape of the ventilation hole, which helps to stabilize the transmission and distribution of airflow, avoid airflow turbulence caused by changes in cross-sectional shape, and further optimize the airflow path inside the refrigerator to improve cooling efficiency and uniformity.

Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
