Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention discloses a warm air type temperature-equalizing wine cabinet, which comprises a cabinet body 200 and an air duct arranged in the cabinet body 200, wherein a plurality of first storage areas 110, second storage areas 120 and third storage areas 130 for placing red wine are vertically arranged in the cabinet body 200 along the height direction of the cabinet body, an evaporation fan 800 and an evaporator 700 are arranged in the air duct, the left side and the right side of the upper part of the air duct are provided with a first air supply opening 511 for supplying air to each layer of the first storage area 110 left and right, a second air supply opening 611 for supplying air to the second storage area 120 and a third air supply opening 612 for supplying air to the third storage area 130, and the air duct is also provided with a first air return opening 613 and a second air return opening 621 for returning air to the first storage area 110, the second storage area 120 and the third storage area 130.
Specifically, for the first air supply opening 511, the air duct supplies cool air to the back of each layer of the first storage area 110 in the horizontal direction from the left side to the right side through the first air supply opening 511, the cool air flows to the front through the left side and the right side of the first storage area 110, and the cool air sinks, and since the first air return opening 613 and the second air return opening 621 are located below the first air supply opening 511, the cool air enters the first air return opening 613 and the second air return opening 621 under the suction force of the first air return opening 613 and the second air return opening 621, so as to form a circulation loop of the air flow. Compared with the traditional wine cabinet air conditioning, the air conditioning is directly blown to the front part from the rear part of the wine cabinet, the horizontal air supply modes on the left side and the right side avoid the air conditioning to directly blow wine bottles, the local temperature fluctuation of the wine bottles is reduced, the internal temperature equalization of the wine cabinet is realized, the storage environment of red wine is improved, and the use experience of a user is improved.
As for the second blowing port 611, the duct supplies cool air to the second storage area 120 through the second blowing port 611, the cool air sinks through the front of the second storage area 120, and enters the first return air port 613 and the second return air port 621 by the suction force of the first return air port 613 and the second return air port 621, forming a circulation loop of the air flow. Similarly, regarding the third blowing port 612, the duct supplies cool air to the third storage area 130 through the third blowing port 612, and the cool air sinks through the front portion of the third storage area 130 and enters the first return air port 613 and the second return air port 621 by the suction force of the first return air port 613 and the second return air port 621, thereby forming a circulation loop of the air flow.
Further, in order to improve the circulation fluidity of the air flow and facilitate the return air, the first return air opening 613 is located between the second supply air opening 611 and the third supply air opening 612, and the second return air opening 621 is located below the third supply air opening 612. Thus, after the cold air output from the plurality of first air supply ports 511 and the second air supply ports 611 at the upper part sinks, a part of the cold air enters the first air return port 613 under the suction effect of the first air return port 613, and the other part of the cold air enters the second air return port 621 under the suction effect of the second air return port 621, so that all the cold air after heat exchange of the wine storage bottle can flow back to the evaporator 700 to enter the next air flow circulation. Meanwhile, the cold air output from the third air supply outlet 612 enters the second air return opening 621 under the suction effect of the second air return opening 621, and flows back to the evaporator 700 to enter the next air flow cycle. The structural design of two return air inlets makes the inside air current circulation of gradevin more smooth and easy, can guarantee that all air conditioning after the heat transfer of storage beverage bottle can both flow back to the evaporimeter and get into next air current circulation, is favorable to improving the inside temperature homogeneity of gradevin.
Further, the second air blowing port 611 includes a second air blowing port a 6111 and a second air blowing port B6112 which are arranged left and right, and the third air blowing port 612 includes a third air blowing port a 6121 and a third air blowing port B6122 which are arranged left and right. The cold air output from the second air outlet a 6111 flows to the front through the back and left sides of the second storage area 120, and the cold air output from the second air outlet B6112 flows to the front through the back and right sides of the second storage area 120. The cold air output from the third air outlet a 6121 flows to the front through the back and left side of the third storage area 130, and the cold air output from the third air outlet B6122 flows to the front through the back and right side of the third storage area 130. The air supply outlet mode of arranging about avoids air conditioning to blow the beverage bottle directly to the front portion by the rear portion, reduces beverage bottle local temperature and undulant, is favorable to realizing the inside samming of gradevin, improves the storage environment of red wine, improves user and uses experience.
Further, in order to guide the airflow, air guide fins a (not shown) are respectively provided on the second air outlet a 6111 and the third air outlet a 6121, and are used for blowing the cold air output from the second air outlet a 6111 to the left side of the second storage area 120 and blowing the cold air output from the third air outlet a 6121 to the left side of the third storage area 130; air guide fins B (not shown) are provided in the second air outlet B6112 and the third air outlet B6122, respectively, for blowing the cold air output from the second air outlet B6112 to the right of the second storage area 120 and blowing the cold air output from the third air outlet B6122 to the right of the third storage area.
Further, the top of the air duct further has a fourth air supply outlet 521, and the cool air blown out from the fourth air supply outlet 521 flows from top to bottom through the front side surface inside the cabinet 200, and finally enters the first air return opening 613 and the second air return opening 621 under the suction effect of the first air return opening 613 and the second air return opening 621. Because the cool air output from the first, second and third air supply outlets 511, 611 and 612 flows from the back of the wine cabinet to the two sides, then flows to the front, sinks and flows back to the first and second air return openings 613 and 621, the temperature of the front of the wine cabinet is slightly higher than that of the back of the wine cabinet, and the temperature difference is compensated by the fourth air supply outlet 521, so as to further improve the temperature uniformity inside the wine cabinet.
