[0027] The utility model embodiment provides a refrigeration device, including a refrigeration compartment, an air duct housing 1 provided with an air duct 11, and an adjustment component, the air duct 11 includes an air duct opening 111 formed in the air duct housing 1 and connected to the refrigeration compartment, the adjustment component includes an air duct opening front cover 2 covered on the air duct opening 111 and an adjustment member 3 slidably connected to the air duct opening front cover 2, the air duct opening front cover 2 is provided with an air outlet 21 corresponding to the air duct opening 111, and the adjustment member 3 slides to adjust the size of the air outlet 21; the air duct housing 1 is provided with a plurality of partitions 13 at the position of the air duct opening 111, the partitions 13 separate the air duct opening 111 into a grid shape, the air duct opening front cover 2 is provided with a buckle 22, and the buckle 22 is snapped on the partition 13 to connect the air duct opening front cover 2 with the air duct housing 1.
[0028] In the refrigeration device provided in the present embodiment, the adjustment component for adjusting the size of the air outlet 21 and thus adjusting the air volume is snap-connected with the air duct housing 1 forming the air duct 11, and no other connection structure is required, so that the air duct opening front cover 2 only needs to be set according to the size of the air duct opening 111, and because the adjustment component only includes the air duct opening front cover 2 and the adjustment member 3, the structure is simple, and the thickness of the air duct opening front cover 2 can also be set thin, so that the overall structure of the adjustment component is simple and small, and will not occupy the space of the refrigeration room.
[0029] Specifically, Figure 2 , 3As shown, a heat preservation layer 12 is provided inside the air duct housing 1, and an air duct 11 for cooling air to flow is formed in the heat preservation layer 12. The air duct opening 111 is extended in the horizontal direction to form a long strip, and the air duct opening 111 protrudes from the air duct 11, and a plurality of partitions 13 are provided at intervals. The shape of the air duct opening front cover 2 matches the air duct opening 111, and buckles 22 are provided at both ends of the air duct opening front cover 2. The buckles 22 at both ends are snap-connected with the partitions 13 at both ends of the air duct opening 111, so as to realize the connection between the air duct opening front cover 2 and the air duct housing 1.
[0030] The air outlet 21 is arranged at the half position of the air duct opening front cover 2 along the length direction. In this embodiment, the air outlet 21 is arranged at the right half of the air duct opening front cover 2 and is in the shape of a long strip. Figure 4 As shown, a guide portion 23 is provided on one side of the air duct front cover 2 close to the air duct housing 1, and a plurality of guide portions 23 are provided. The plurality of guide portions 23 are spaced apart on both sides of the air outlet 21 along the length direction of the air outlet 21, or in other words, are spaced apart on both sides of the air outlet 21 in the moving direction of the adjustment member 3.
[0031] The adjusting member 3 includes a baffle 31 and a paddle 32 connected to the baffle 31. The baffle 31 has the same shape as the air outlet 21 and is also in the shape of an elongated strip. The two long sides of the baffle 31 are clamped between the guide portions 23 on both sides of the air outlet 21 to achieve the connection between the adjusting member 3 and the air duct front cover 2, and the adjusting member 3 can move along the length direction of the air outlet 21 under the guidance of the guide portions 23.
[0032] The left half of the air duct front cover 2 is to make way for the baffle 31. The paddle 32 is connected to the right end of the baffle 31. After the paddle 32 is connected to the baffle 31, it protrudes from the air outlet 21 into the refrigeration room to facilitate the user to adjust the size of the air outlet 21. The baffle 31 gradually covers the air outlet 21 by moving the paddle 32 to the right, making the air outlet 21 smaller and reducing the air volume; it moves to the left to the left half of the air duct front cover 2, making the air outlet 21 larger and increasing the air volume.
[0033] Furthermore, a convex block 24 is provided at a position of the air duct front cover 2 close to the air outlet 21, and the convex block 24 is spaced apart from the air outlet 21. A convex rib 311 is provided on the baffle 31 for abutting against the convex block 24 for position limiting. In this embodiment, the convex rib 311 is provided in three groups, including a first group of convex ribs, a second group of convex ribs and a third group of convex ribs.
[0034] The first group of convex ribs is provided with a convex rib 311 and is arranged close to the paddle 32, the second group of convex ribs is provided with two convex ribs, the two convex ribs 311 in the second group of convex ribs are arranged on the side of the first group of convex ribs away from the paddle 32 and are spaced apart from the first group of convex ribs, the third group of convex ribs is provided with a convex rib and is arranged on the side of the second group of convex ribs away from the first group of convex ribs, and the third group of convex ribs is spaced apart from the second group of convex ribs.
[0035] The distance between the first group of ribs and the paddle 32 is greater than the distance between the protrusion 24 and the air outlet 21. When the first group of ribs abuts against the side of the protrusion 24 away from the air outlet 21, the air outlet 21 is in the first gear position. Figure 3 The figure shows a schematic diagram of the air outlet 21 in the first gear position. When the adjusting member 3 moves to the right, the convex block 24 limits the first group of convex ribs and prevents it from moving to the right. When the adjusting member 3 moves to the left, the left side of the air outlet 21 limits the paddle 32, so that the adjusting member 3 can only move within a short distance. The size of the air outlet 21 is the largest within this small range.
[0036] Preferably, the distance between the first group of ribs and the paddle 32 is equal to the distance between the left side of the air outlet 21 and the side of the convex block 24 away from the air outlet 21, so that the adjustment member 3 cannot move left and right, and the air outlet 21 has a stable air volume when the air outlet 21 is in the first gear. More preferably, when the air outlet 21 is in the first gear, the paddle 32 is located at the left end of the air outlet 21.
[0037] The distance between the two convex ribs 311 in the second group of convex ribs is greater than the width of the protrusion 24 in the horizontal direction. When the protrusion 24 is disposed between the two convex ribs 311 in the second group of convex ribs, the air outlet 21 is located at the second gear position. When the adjusting member 3 moves left and right, the two convex ribs 311 in the second group of convex ribs are limited by the two sides of the protrusion 24. The adjusting member 3 can only move within the distance range between the two convex ribs 311 in the second group of convex ribs. Within this range, the size of the air outlet 21 is centered.
[0038] Preferably, the distance between the two convex ribs 311 in the second group of convex ribs is equal to the width of the protrusion 24, that is, when the protrusion 24 is located in the second group of convex ribs, the adjustment member 3 cannot move left and right, so that the air outlet 21 has a stable air volume when the air outlet 21 is in the second gear. More preferably, when the air outlet 21 is in the second gear, the paddle 32 is located in the middle of the air outlet 21.
[0039] When the third group of convex ribs abuts against the side of the protrusion 24 close to the air outlet 21, the air outlet 21 is in the third gear. Preferably, the length of the baffle 31 does not exceed the length of the air outlet 21, and the third group of convex ribs is set at the leftmost end of the baffle 31. At this time, the baffle 31 is almost completely within the range of the air outlet 21. When the adjustment member 3 moves to the left, the protrusion 24 limits the third group of convex ribs. When the adjustment member 3 moves to the right, the air outlet 21 on the right side of the baffle 31 becomes smaller, but the air outlet 21 on the left side becomes larger, that is, the size of the air outlet 21 can be maintained unchanged, and the air volume of the air outlet 21 can be stable when the air outlet 21 is in the third gear.
[0040] The user can move the baffle 31 through the paddle 32 to adjust the size of the air outlet 21 as needed. Due to the limitation between the protrusion 24 and the rib 311, it is necessary to increase the pushing force when switching between the gears so that the rib 311 can cross the protrusion 24. At the same time, the user can have an obvious sense of frustration, allowing the user to feel the aforementioned three gears.
[0041] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
[0042] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model. They are not intended to limit the protection scope of the utility model. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.
