[0073] Refrigeration equipment includes:

[0074] A box body 100, wherein a storage chamber 120 is formed inside the box body 100;

[0075] The box body 100 includes a box shell and an inner container component 110 disposed in the box shell. A storage chamber 120 for storing food is defined inside the inner container component 110 .

[0076] The storage chamber 120 has an opening 121 for allowing a user to take out food stored in the storage chamber 120 through the opening 121 .

[0077] A door body is connected to the box body 100 , and the door body is rotatably connected to the box body 100 , so as to open or close the storage chamber 120 .

[0078] In order to refrigerate or freeze the food in the storage chamber 120 in the box body 100, the refrigeration device is also correspondingly arranged with a refrigeration system.

[0079] The refrigeration system is formed by connecting a compressor, a four-way valve, a condenser and an evaporator through a refrigerant pipeline. The refrigeration cycle of the refrigeration system is used to refrigerate or freeze the food in the storage chamber 120.

[0080] In this embodiment, when the refrigeration device is placed normally for use, the opening 121 faces the user, the side corresponding to the opening 121 is the front side, and the side opposite to the opening 121 corresponds to the rear side of the refrigeration device, the depth direction of the refrigeration device corresponds to the front-to-back direction, and the width direction of the refrigeration device corresponds to the left-to-right direction.

[0081] The air duct assembly 200 is assembled on the inner liner component 110 and is surrounded by the inner liner component 110 to form an air duct; the air duct is communicated with the storage chamber 120, and an air outlet 221 is formed on the air duct assembly 200;

[0082] In some embodiments of the present application, the air duct assembly 200 includes:

[0083] The air duct cover assembly comprises:

[0084] The air duct decoration plate 230 , the air duct foam plate 220 and the air duct cover plate 210 .

[0085] When connected, the duct cover plate 210 is arranged in the middle position between the duct foam plate 220 and the duct decorative plate 230. The duct decorative plate 230 is a single-layer metal decorative plate, which is arranged at a position close to one side of the storage chamber 120, while the duct foam plate 220 is arranged at a position away from the side of the storage chamber 120.

[0086] The air duct device plate and the air duct cover plate 210 are fixedly connected;

[0087] The air duct foam plate 220 is arranged in close contact with the air duct cover plate 210 and is connected and fixed to the air duct cover plate 210 to achieve connection between the air duct cover plate 210 and the air duct decorative plate 230 and the air duct foam plate 220 .

[0088] The air duct assembly 200 further includes a connecting plate 240 disposed at the bottom of the air duct cover plate 210 .

[0089] The air duct cover plate assembly is assembled on the inner tank component 110, and the air duct cover plate assembly, the inner tank component 110 and the connecting plate 240 are connected together to form an air duct.

[0090] An air inlet communicating with the storage chamber 120 is formed at the bottom of the air duct to facilitate air flow into the interior of the air duct;

[0091] An air outlet 221 is correspondingly formed on the air duct cover assembly at the middle position of the air duct, so as to discharge the airflow in the air duct into the storage chamber 120 .

[0092] When cooling the storage chamber 120 , air is sucked in through the air inlet at the bottom, cooled by the evaporator, and then blown out from the air outlet 221 , so as to achieve the effect of cooling the storage chamber 120 .

[0093] The air duct foam plate 220 is close to the air duct. In some embodiments, the air outlet 221 is disposed on the air duct foam plate 220 .

[0094] The air outlet portion 221 is a long air outlet opened along the width direction of the refrigeration device, which can guide the airflow in the air duct to the outside.

[0095] In some embodiments of the present application, in order to achieve the effect of directing the airflow in the air duct into the storage chamber 120,

[0096] An air outlet channel is formed on the air duct cover plate 210 , the air duct foam plate 220 and the air duct decorative plate 230 .

[0097] The air outlet channel includes: an air outlet portion 221 opened on the air duct foam plate 220 , a first air outlet 214 provided on the air duct cover plate 210 , and a second air outlet 231 on the air duct decorative plate 230 .

[0098] The positions of the first air outlet 214 , the second air outlet 231 and the air outlet portion 221 are correspondingly arranged, and the airflow from the air outlet portion 221 can enter the first air outlet 214 , and then enter the second air outlet 231 through the first air outlet 214 and then enter the interior of the storage chamber 120 .

[0099] An air outlet channel is formed on the air duct cover assembly, and the air flows from the first air outlet 214 to the second air outlet 231 and is blown out from the third air outlet.

[0100] In some embodiments of the present application, the first air outlet 214 , the second air outlet 231 , and the air outlet portion 221 are configured to be completely identical in size and shape, and have one-to-one corresponding positions, to ensure that the airflow flowing out of the air outlet portion 221 will not be lost.

[0101] In some embodiments of the present application, in order to ensure that as much air as possible in the air duct flows to the air outlet 221 and the air flow to the air outlet 221 does not become turbulent, air guide channels 223 are formed on both sides of the air outlet 221.

[0102] In order to achieve a better guiding effect on the airflow, the inner diameter of the air guide channel 223 gradually decreases from the direction away from the air outlet 221 to the direction close to the air outlet 221. The inner diameter is large at a location away from the air outlet 221, so that the airflow can enter the air guide channel 223 more easily. As it approaches the air outlet 221, the inner diameter gradually decreases, and its minimum inner diameter is the same as the height of the air outlet 221, so that the airflow can be just appropriately introduced into the position of the air outlet 221.

[0103] The drawer cover 310 is assembled in the storage chamber 120 .

[0104] When fixing, a load-bearing rib is provided on the inner tank component 110, and the drawer cover 310 is assembled and fixed on the load-bearing rib. The drawer cover is extended from the back to the front along the depth direction of the refrigeration equipment.

[0105] In some embodiments of the present application, the refrigeration device further includes a drawer body 320 , and the drawer body 320 can be slidably connected to the inner wall of the storage chamber 120 to achieve the function of being pulled open or closed relative to the storage chamber 120 .

[0106] When it is necessary to place or take out items, the drawer body 320 can be pulled outward along the depth direction of the refrigeration device. When the drawer body 320 is closed, the drawer cover is arranged above it to seal it.

[0107] In some embodiments of the present application, in order to adjust the air volume of the air outlet portion 221, the refrigeration device is correspondingly configured with a damper adjustment mechanism.

[0108] The damper adjustment mechanism includes:

[0109] The sliding component 400 is assembled in the air duct assembly 200 and corresponds to the position of the air outlet portion 221;

[0110] In some embodiments of the present application, the sliding component 400 is a sliding adjustment block that can slide back and forth along the width direction of the air outlet.

[0111] When arranged, the sliding component 400 is arranged at a spatial position between the air duct foam plate 220 and the air duct cover plate 210 , and is slidably connected to the air duct cover plate 210 .

[0112] The air outlet area of ​​the air outlet portion 221 can be adjusted and controlled by sliding the sliding component 400 back and forth.

[0113] The adjustment operating member 500 is mounted at a position of the drawer cover 310 close to the opening 121;

[0114] The adjustment operating member 500 is arranged near the opening 121 of the box body 100, so that when the user makes adjustments, he can operate the adjustment operating member 500 at the opening 121 by opening the door body, without the user having to reach into the back panel at the deepest position of the storage room 120 for adjustment, which makes the adjustment operation more convenient.

[0115] A swing component 600 is hinged on the drawer cover 310, one end of which is connected to the adjustment operating member 500, and the other end of which is connected to the sliding component 400;

[0116] During adjustment, the power of the adjustment operating member 500 can be transferred and transmitted to the sliding component 400 .

[0117] By arranging the swing component 600 in a manner that extends along the depth direction of the refrigeration equipment, the adjustment operating member 500 can be arranged at a position close to the opening portion 121, and the sliding component 400 can also be arranged in the air duct assembly 200, thereby realizing the connection between the adjustment operating member 500 and the sliding component 400.

[0118] When the adjusting operating member 500 is adjusted, the swinging member 600 swings to drive the sliding member 400 to slide so as to change the air outlet area of ​​the air outlet portion 221 .

[0119] Since the swing component 600 is hinged on the drawer cover 310, when the force acts on the adjusting operating member 500, the adjusting operating member 500 can be driven to swing. The swing of the adjusting operating member 500 can drive the sliding component 400 to slide, so as to adjust the air volume of the air outlet part 221.

[0120] The refrigeration device is provided with an adjusting operating member 500 near the opening portion 121, and a swinging member 600 arranged along the depth direction of the refrigeration device and connected to the adjusting operating member 500 at one end and connected to the sliding member 400 at the other end, so that the power of the adjusting operating member 500 can be transmitted to the sliding member 400; when making adjustments, the user only needs to twist the adjusting operating member 500 near the opening portion 121 to transmit power to the swinging member 600, thereby driving the sliding member 400 located inside the air duct assembly 200 connected to the swinging member 600 to slide, thereby adjusting the air outlet area of ​​the air outlet portion 221, thereby achieving the adjustment of the air outlet volume. During the adjustment operation, the user does not need to extend his hand into the back panel position of the storage chamber 120 for adjustment, and the user's adjustment operation is more convenient and quick.

[0121] In some embodiments of the present application, the sliding component 400 includes: a through portion 410, which is disposed through the sliding component 400, arranged at one end of the sliding component 400, and disposed along the length direction of the sliding component 400;

[0122] The shielding portion 420 is arranged at the other end of the sliding component 400 and is arranged along the length direction of the sliding component 400;

[0123] When the swing component 600 swings, the corresponding areas of the through portion 410 and the shielding portion 420 and the air outlet portion 221 can be changed to change the air outlet area of ​​the air outlet portion 221 .

[0124] The through portion 410 is a through hole provided through the sliding component 400 , and the through hole may be a through elongated hole or a through circular hole.

[0125] The shielding portion 420 is formed by the main body of the sliding component 400 , which is not through-through and can be used to shield the air outlet portion 221 .

[0126] When the sliding component 400 is arranged, it is set at a position corresponding to the position of the air outlet portion 221. When the sliding component 400 slides along the width direction of the air outlet portion 221, it will change the corresponding areas of the shielding portion 420 and the through portion 410 and the air outlet portion 221. When the corresponding areas of the through portion 410 and the shielding portion 420 and the air outlet 221 are different, the shielding area of ​​the air outlet 221 is also different, thereby realizing the adjustment of the size of the air outlet area of ​​the air outlet 221 and realizing the adjustment of the air outlet volume.

[0127] During the adjustment, the adjustment can be made according to the ambient temperature requirements in the storage chamber 120. For example, when the ambient temperature of the storage chamber 120 is high, the corresponding areas of the through portion 410 and the air outlet portion 221 can be made larger, and the corresponding areas of the shielding portion 420 and the air outlet portion 221 can be made smaller, so that a large amount of airflow can enter the storage chamber 120 for cooling.

[0128] During the sliding process of the sliding component 400, there may be a situation where a portion of the through portion 410 corresponds to the air outlet portion 221, and a portion of the shielding portion 420 corresponds to the air outlet portion 221, that is, a portion of the air outlet portion 221 is shielded;

[0129] There may also be a situation where the shielding portion 420 does not correspond to the air outlet portion 221 at all, the air outlet portion 221 is not shielded, and the air outlet area is maximized;

[0130] Alternatively, the shielding portion 420 shields most of the area of ​​the air outlet portion 221 , and only a small amount of air flows into the storage chamber 120 .

[0131] In some embodiments of the present application, the sliding component 400 is formed with: a first sliding channel 430 extending along the sliding direction of the sliding component 400 , and a first sliding top wall portion 431 is formed on the first sliding channel 430 ;

[0132] A second sliding channel 440 is disposed below the first sliding channel 430 and extends along the sliding direction of the sliding component 400 . A second sliding bottom wall portion 441 is formed on the second sliding channel 440 .

[0133] The through portion 410 is arranged below the second sliding channel 440 .

[0134] The air duct cover plate 210 is formed with:
