Abstract

The present application provides a refrigerator. The refrigerator includes a compartment for storing items. An air outlet and a return air outlet are provided in the compartment. The air outlet and the return air outlet are located on a first inner wall of the compartment. The air outlet is used to supply cold air into the compartment, and the return air outlet is used to recover cold air from the compartment. The refrigerator also includes an air supply mechanism installed in the compartment. The air supply mechanism is provided with a first air supply outlet. The first air supply outlet supplies cold air toward a second inner wall of the compartment opposite to the return air outlet. When the refrigerator is in operation, cold air is supplied directly to the second inner wall of the compartment opposite to the return air outlet through the air supply mechanism. This allows for targeted cold air supply to locations in the compartment that lack cold air, and for cold air to be added to areas in the compartment that have temperatures higher than a set temperature to achieve cooling. This improves the temperature uniformity of the space, allowing food placed in the compartment to be cooled uniformly overall, thereby improving food preservation.

Description

Technical Field

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

[0002] Currently, all air-cooled refrigerators on the market use forced air convection for cooling, using fans to blow cool air that circulates throughout the refrigerator compartment to cool the compartment. The proper distribution and distribution of air outlets significantly influence the temperature uniformity within the storage compartment. There are two main distribution methods for compartment air outlets: one is to create multiple rectangular outlets on the rear wall of the inner container, and the other is to densely distribute multiple outlets on the upper wall of the inner container.

[0003] The first method is that the cold air is blown out from the air outlet vertically to the door liner wall and then turns back to form a circulation in the compartment to achieve cooling. This method causes the cold air to have a higher wind speed from the air outlet to the stage when it hits the inner wall of the door liner. The wind speed decreases as it spreads from the inner wall of the door liner to the surrounding areas, causing the cold air to be unevenly distributed up and down, left and right in the storage room, affecting the temperature uniformity in the room. In particular, when food is placed in the compartment, its obstruction to the airflow will make the temperature uniformity in the room worse.

[0004] The second method involves cooling the storage compartment by blowing cold air vertically downward from the vents. Once it hits the lower wall, it circulates back to cool the compartment. This method, with densely distributed vents along the upper wall of the inner container, improves temperature uniformity in any plane parallel to the vents. However, temperature uniformity in planes at different heights remains poor. Similarly, temperature uniformity in the compartment worsens when food is placed inside. Summary of the Invention

[0005] An embodiment of the present invention provides a refrigerator to solve the technical problem of poor refrigeration uniformity in refrigerators in the prior art.

[0006] An embodiment of the present application provides a refrigerator, comprising: a compartment, the compartment being used for storing items, an air outlet and a return air outlet being provided in the compartment, the air outlet and the return air outlet being located on a first inner wall in the compartment, the air outlet being used to supply cold air into the compartment, and the return air outlet being used to recover cold air from the compartment; an air supply mechanism being installed in the compartment, the air supply mechanism being provided with a first air supply outlet, the first air supply outlet supplying cold air toward a second inner wall in the compartment opposite to the return air outlet.

[0007] In one embodiment, the air outlet is located in the northwest direction of the compartment, the return air outlet is located in the northeast direction of the compartment, and the first air supply outlet is directed toward the southeast direction of the compartment. The northwest direction is the left side of the first inner wall in the compartment, the northeast direction is the right side of the first inner wall in the compartment, and the southeast direction is the right side of the second inner wall in the compartment.

[0008] In one embodiment, the air supply mechanism is further provided with a second air supply port, which discharges air toward the southwest direction in the compartment, where the southwest direction is the left side of the second inner wall in the compartment.

[0009] In one embodiment, the air supply mechanism is further provided with a third air supply port, and the third air supply port discharges air toward the northwest direction in the compartment.

[0010] In one embodiment, the air outlet area of ​​the first air supply port is greater than the air outlet area of ​​the second air supply port, and the air outlet area of ​​the first air supply port is greater than the air outlet area of ​​the third air supply port.

[0011] In one embodiment, the refrigerator further comprises a temperature sensor, and the temperature sensor is located at a second inner wall position opposite to the return air outlet in the compartment.

[0012] In one embodiment, the refrigerator also includes a controller, which is electrically connected to the temperature sensor and the air supply mechanism. The controller is used to receive the actual temperature value detected by the temperature sensor. When the difference between the actual temperature value and the set temperature value is greater than a value, the controller controls the air supply mechanism to discharge air, a>0.

[0013] In one embodiment, the refrigerator further includes an air duct member, which is respectively connected to the air outlet and the air supply mechanism.

[0014] In one embodiment, the air outlet and the return air outlet are located on the wall opposite to the opening of the compartment at intervals.

[0016] In one embodiment, the air supply mechanism is rotatably mounted in the compartment.

[0017] In the above embodiment, when the refrigerator is in operation, cold air is supplied directly to the second inner wall of the compartment opposite to the return air outlet through the air supply mechanism, so that cold air can be supplied to the location in the compartment that lacks cold air, and cold air can be supplemented to the area in the compartment where the temperature is higher than the set temperature to achieve cooling, thereby improving the temperature uniformity of the space, so that the food placed in the compartment can be cooled evenly as a whole, thereby improving the preservation of the food.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0025] like Figure 1 and Figure 2 As shown, the refrigerator of the present invention includes a compartment 10, which is used for storing items. An air outlet 11 and an air return vent 12 are provided in the compartment 10. The air outlet 11 and the air return vent 12 are located on a first inner wall of the compartment 10. The air outlet 11 is used to supply cold air into the compartment 10, and the air return vent 12 is used to recover cold air from the compartment 10. When in use, the cold air blown out of the air outlet 11 will enter the return vent 12 after circulating in the compartment 10. Under the continuous negative pressure of the return vent 12, the cold air blown out of the air outlet 11 is often recovered by the return vent 12 before reaching the second inner wall of the compartment 10 opposite to the return vent 12, resulting in uneven cooling at the second inner wall opposite to the return vent 12.

[0026] To this end, in the technical solution of the present invention, the refrigerator also includes an air supply mechanism 20, which is installed in the compartment 10. A first air supply port 21 is provided on the air supply mechanism 20, and the first air supply port 21 supplies cold air toward the second inner wall in the compartment 10 opposite to the return air port 12.

[0027] By applying the technical solution of the present invention, when the refrigerator is in operation, cold air is supplied directly toward the second inner wall of the compartment 10 opposite to the return air port 12 through the air supply mechanism 20, so that cold air can be supplied to the position in the compartment 10 that lacks cold air, and cold air can be supplemented to the area in the compartment 10 where the temperature is higher than the set temperature to achieve cooling, thereby improving the temperature uniformity of the space, so that the food placed in the compartment can be cooled evenly as a whole, thereby improving the preservation of the food.

[0028] It should be noted that in the technical solution of the present invention, the compartment 10 is a rectangular space with a switchable door, and the compartment 10 can be opened or closed by opening and closing the door. The above-mentioned first inner wall is the inner wall of the compartment 10 opposite the switchable door, that is, the innermost back of the compartment 10; the second inner wall is the inner wall of the switchable door of the compartment 10. The above-mentioned first inner wall and second inner wall do not constitute a limitation on the specific inner walls of the compartment 10. As long as the two opposite first inner walls, the second inner wall and their respective air vents meet the above-mentioned positional correspondence, the above-mentioned technical solution can be adopted.

[0029] like Figure 1 As shown, the compartment 10 can be mainly divided into four areas: northeast, southeast, northwest and southwest. Among them, the air outlet 11 is located in the northwest direction of the compartment 10, and the return air outlet 12 is located in the northeast direction of the compartment 10. The southeast direction is the area where the cooling capacity in the compartment 10 is insufficient, and the air is discharged toward the southeast direction of the compartment 10 through the first air supply port 21 to improve the temperature uniformity of the space. The northwest direction is the left side of the first inner wall in the compartment 10, the northeast direction is the right side of the first inner wall in the compartment 10, the southeast direction is the right side of the second inner wall in the compartment 10, and the southwest direction is the left side of the second inner wall in the compartment 10.

[0030] It should be noted that, in the technical solution of the present invention, the directions of east, south, west and north and the regional divisions of northeast, southeast, northwest and southwest are only a description method for the convenience of clearly and briefly explaining the technical solution of the present invention, and do not constitute a limitation on the use direction of a specific product. Figure 2 As shown, the air outlet 11 and the return air outlet 12 are located at intervals on the wall opposite the opening of the compartment 10. The second inner wall of the compartment 10 opposite the return air outlet 12 is located near the door. As other optional embodiments, the air outlet 11 and the return air outlet 12 can also be located at intervals on other surfaces within the compartment 10. Optionally, in the technical solution of this embodiment, the air supply mechanism 20 is installed on the top surface of the compartment 10. In the technical solution of this embodiment, the compartment 10 is a rectangular parallelepiped.

[0031] During use, the temperature is lowest on the north side of the compartment 10 because both the air outlet 11 and the return air outlet 12 are located on the north side. The cold air eventually flows through this area and enters the return air outlet 12, resulting in the highest cooling capacity and lowest temperature in this area. The southeast and southwest regions are both hotter than the northeast region because the cold air from the air outlet 11 is often drawn back by the return air outlet 12 before reaching the second inner wall of the compartment 10, which is opposite the return air outlet 12. This results in the highest temperature in the southeast region.

[0032] like Figure 2 、 Figure 3 and Figure 5As shown, the air supply mechanism 20 is further provided with a second air supply port 22, which discharges air toward the southwest direction of the compartment 10. From the above analysis, it can be seen that the temperature in the southwest region of the compartment 10 is still higher than that in the northeast region. Therefore, by discharging air toward the southwest direction through the second air supply port 22, the temperature uniformity of the space can also be improved.

[0033] like Figure 2 and Figure 4 As shown, the air supply mechanism 20 is further provided with a third air supply port 23, which discharges air toward the northwest direction in the compartment 10. Since all the cold air will eventually pass through the northeast region where the return air port 12 is located, resulting in the lowest temperature in the northeast region, the third air supply port 23 discharges air toward the northwest direction in the compartment 10, which can improve the temperature uniformity of the space to a certain extent.

[0034] In the technical solution of the present invention, the air outlet area of ​​the first air supply port 21 is larger than the air outlet area of ​​the second air supply port 22, and the air outlet area of ​​the first air supply port 21 is larger than the air outlet area of ​​the third air supply port 23. Since the temperature in the southeast region is the highest and the amount of cooling required is also the largest, the air outlet area of ​​the first air supply port 21 is set to the largest. The temperature difference between the southwest region and the northwest region in the compartment 10 is not large, so the air outlet area of ​​the second air supply port 22 and the air outlet area of ​​the third air supply port 23 can be equal. Optionally, the first air supply port 21 is elliptical. The second air supply port 22 and / or the third air supply port 23 are circular. As other optional embodiments, the first air supply port 21, the second air supply port 22 and the third air supply port 23 can also be designed as any other shape such as Z-shaped, W-shaped and M-shaped air outlets.

[0035] More preferably, Figure 2 As shown, in the technical solution of the present invention, the refrigerator also includes a temperature sensor 30, which is located at a second inner wall position opposite to the return air outlet 12 in the compartment 10. After a temperature uniformity test, it was found that the temperature at the second inner wall position opposite to the return air outlet 12 in the compartment 10 was higher than that in other areas. Therefore, the temperature sensor 30 is set at the second inner wall position opposite to the return air outlet 12 in the compartment 10 to perform targeted temperature detection. More preferably, the refrigerator also includes a controller, which is electrically connected to the temperature sensor 30 and the air supply mechanism 20. The controller is used to receive the actual temperature value detected by the temperature sensor 30. When the difference between the actual temperature value and the set temperature value is greater than a value, the controller controls the air supply mechanism 20 to discharge air, where a>0.

[0036] like Figure 2 As shown, the refrigerator further includes an air duct member 40, which is respectively connected to the air outlet 11 and the air supply mechanism 20. Figure 3As shown, the air supply mechanism 20 is further provided with an air inlet 24 , and the air duct member 40 is connected to the air inlet 24 .

[0037] As a preferred embodiment, the air supply mechanism 20 is rotatably installed in the compartment 10 to improve the temperature uniformity of the space in the compartment 10.

[0038] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
