Detailed Implementation

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] Furthermore, it should be understood that although the terms "first," "second," etc., may be used herein to describe various elements or structures, the objects being described should not be limited by these terms. These terms are only used to distinguish these objects from one another. For example, a first connecting part may be referred to as a second connecting part, and similarly, a second connecting part may be referred to as a first connecting part, without departing from the scope of protection of this application.

[0029] This application provides an air guide assembly 10, such as... Figure 1 As shown, it includes a frame 1 and an air guide 2. The frame 1 is provided with a first connecting part 11 and an adjusting part 12. The adjusting part 12 has at least two adjusting positions.

[0030] The air guide 2 is provided with a second connecting part and a mating part. The second connecting part is rotatably connected to the first connecting part 11 about a first axis. The mating part is mated with the adjusting part 12. When the air guide 2 rotates about the first axis as the central axis, the mating part and the adjusting part 12 are mated at different adjustment levels, thereby locking the air guiding direction of the air guide 2.

[0031] In the air guide assembly 10 of this application, the frame 1 and the air guide 2 are rotatably connected by the first connecting part 11 and the second connecting part, so that the air guide 2 can rotate about the first axis as the central axis, thereby adjusting the angle of the air guide 2 according to the wind direction requirements, and thus adjusting the flow direction of the air passing through the air guide 2.

[0032] The mating part of the air guide 2 cooperates with the different adjustment positions of the adjustment part 12 to lock the position of the air guide 2 after rotation.

[0033] The air guide assembly 10 provided in this application can be fixed to the air outlet and / or return air outlet of the refrigeration equipment to adjust the air direction inside the refrigeration equipment.

[0034] In some embodiments, the second connecting part is configured as a rotating shaft 21, the first connecting part 11 is provided with a transition hole 111 for connecting the rotating shaft 21, and the first axis is coaxial with the central axis of the rotating shaft 21.

[0035] The air guide 2 is connected to the frame 1 by setting a rotating shaft 21 and a connecting hole 111, which not only provides the first axis of rotation of the air guide 2, but also allows the air guide 2 to be rotatably connected to the frame 1.

[0036] In some embodiments, the adjustment part 12 is provided with at least two adjustment holes 121 to form at least two adjustment positions; the mating part is provided with a protrusion 22 corresponding to the adjustment hole 121, and the protrusion 22 is disposed in the adjustment hole 121.

[0037] like Figure 1In the middle, the adjustment part 12 is provided at both ends of the air guide 2 along the extension direction of the first axis, so as to ensure the stability of the air guide 2. The adjustment part 12 is provided with multiple adjustment holes 121, and the protrusion 22 provided on the air guide 2 is engaged in different adjustment holes 121, so as to adapt to the position locking of the air guide 2 after tilting at different angles.

[0038] In some embodiments, at least two adjustment holes 121 are arranged circumferentially around a first axis.

[0039] When the air guide 2 rotates around the first axis, all positions on the air guide 2 rotate around the first axis, and the arrangement of the adjustment holes 121 is set to be arranged circumferentially around the first axis.

[0040] This allows the protrusions 22 on the air guide 2 to engage with the adjustment holes 121 at different positions in sequence when the air guide 2 rotates.

[0041] In some embodiments, an adjustment hole 13 is provided on the side of the frame 1 next to the adjustment part 12.

[0042] When adjusting the angle of the air guide 2, the protrusion 22 on the air guide 2 needs to disengage from the original adjustment hole 121 and be inserted into other adjustment holes 121. During the process of the protrusion 22 disengaging and being inserted, the adjustment part 12 needs to have a certain deformation.

[0043] Therefore, providing an adjustment hole 13 at the connection point between the adjustment part 12 and the frame 1 can assist in the adjustment and reduce the difficulty of adjustment.

[0044] In some embodiments, the adjustment hole 13 is an elongated hole and extends along the length direction of the connection between the adjustment part 12 and the frame 1.

[0045] To reduce production costs, the thickness of the adjustment part 12 is usually set to be thin. Therefore, the connection between the adjustment part 12 and the frame 1 is elongated. The adjustment hole 13 is also elongated and is located on the side of the adjustment part 12, which can increase the deformation of the adjustment part 12.

[0046] In some embodiments, two first connecting portions 11 are provided, and the two first connecting portions 11 are provided at both ends of the air guide member 2 along the extension direction of the first axis, and one of the two first connecting portions 11 has an upward-opening notch.

[0047] The two adapter holes 111 provided on the two first connecting parts 11 are arranged opposite to each other, or in other words, the two adapter holes 111 provided on the two first connecting parts 11 are coaxial with the first axis, so that both ends of the rotating shaft 21 can enter the two adapter holes 111 and rotate in the two adapter holes 111, thereby driving the air guide 2 to rotate.

[0048] One of the two first connecting parts 11 has an upward-opening notch, so that after one end of the rotating shaft 21 is inserted into the adapter hole 111 without the notch, the other end overlaps the first connecting part 11 with the notch from top to bottom, which facilitates the installation of the rotating shaft 21.

[0049] Of course, it is conceivable that the connection between the rotating shaft 21 and the first connecting part 11 can also be in other ways, such as the rotating shaft 21 being telescopic, or the two first connecting parts 11 having greater elasticity, which can make way for the end of the rotating shaft 21 when the rotating shaft 21 is installed.

[0050] In some embodiments, in the direction of the line connecting the first connecting part 11 and the adjusting part 12, the side of the air guide 2 near the adjusting part 12 is an arc surface, and the arc surface is centered on the first axis.

[0051] The side of the air guide 2 closest to the adjustment part 12 is the side where the air guide 2 rotates more during rotation. This side is set as an arc surface, and the arc surface is centered on the first axis so that the side of the air guide 2 is always in contact with the inner side of the frame 1 during rotation.

[0052] This prevents the air guide 2 from forming a gap with the inner side of the frame 1 during rotation, which would prevent the air passing through the gap from being guided by the air guide 2.

[0053] Of course, it is conceivable that the side of the air guide 2 near the first connecting part 11 can also be set as an arc surface, which also avoids the formation of a gap between the air guide 2 and the inner side of the frame 1.

[0054] like Figure 1 In the middle, the part of the rotating shaft 21 except for the part that extends into the adapter hole 111 is hollowed out, leaving only the arc-shaped bottom, and the arc-shaped bottom is used as the side of the air guide 2 to cooperate with the inner side of the frame 1.

[0055] In addition, it can reduce the production cost of the air guide component 2.

[0056] like Figure 1 In the middle, there are three air guides 2 inside the frame 1. The top surface of the uppermost air guide 2 is always in contact with the inner top of the frame 1, and the bottom surface of the lowermost air guide 2 is always in contact with the inner bottom of the frame 1.

[0057] Between two adjacent air guides 2, the bottom surface of the upper air guide 2 is always in contact with the top surface of the lower air guide 2.

[0058] In some embodiments, a buckle 14 is provided on the side of the frame 1 away from the first connecting part 11 and the adjusting part 12, so that the air guide assembly 10 in this application can be fixed to the air duct or other structure forming the air outlet by means of the buckle 14.

[0059] An embodiment of this application also provides a refrigeration device, which includes an air duct with an air outlet and an air guide assembly disposed at the air outlet position, wherein the air guide assembly is the aforementioned air guide assembly 10.

[0060] The refrigeration equipment can be a horizontal freezer. The horizontal freezer includes an inner liner 3 and an air duct disposed in the inner liner 3. Specifically, the inner liner 3 encloses a receiving space and includes a step portion 32 and a first side wall 33. The step portion 32 is located at the bottom of one end of the receiving space in a first direction. There are two first side walls 33. The two first side walls 33 are parallel to and opposite to the first direction, which is the length direction of the horizontal freezer, or the left-right direction.

[0061] The horizontal freezer also includes an evaporator compartment cover 34 disposed in the housing space, which divides the housing space into a refrigeration compartment 31 for storage and an evaporator compartment in which the evaporator is disposed.

[0062] The air duct includes an upper air duct 51, a lower air duct 52 and a vertical air duct 53. The upper air duct 51 and the lower air duct 52 are arranged at intervals in the vertical direction. The vertical air duct 53 connects the upper air duct 51 and the evaporator compartment. Multiple air outlets are arranged at intervals in both the upper air duct 51 and the lower air duct 52. Air guide components 10 are fixed at the air outlets by clips 14.

[0063] Of course, the air duct can also be configured with only one upper air duct 51 connected to the evaporator compartment via a vertical air duct 53, or only one lower air duct 52 connected to the evaporator compartment, or even just one located in... Figure 5 The horizontal air duct between the upper-middle air duct 51 and the lower-middle air duct 52, or in Figure 5 A horizontal air duct is added between the upper-middle air duct 51 and the lower-middle air duct 52.

[0064] In some embodiments of this application, the housing also includes an outer shell 4, an upper air duct 51 and a vertical air duct 53 protruding from the inner liner 3 toward the outer shell 4, and a lower air duct 52 protruding from the inner liner 3 toward the interior of the refrigeration chamber 31.

[0065] In horizontal freezers, food baskets are usually hung above the refrigeration compartment 31 to increase partitioning. The upper air duct 51 and the vertical air duct 53 are hidden between the inner liner 3 and the outer shell 4, so they will not interfere with the installation of the food baskets, nor will the protruding air ducts at the top reduce the distance between the front and back of the food baskets.

[0066] The downdraft duct 52 protrudes from the refrigeration compartment 31 and can serve as a mounting bracket for the food basket, thus sharing some of the load on the food basket.

[0067] Regarding the installation of the upwind duct 51 and the downwind duct 52, the specifics are as follows: Figure 5In the middle, the upper air duct 51 includes an upper air duct shell 511 and an upper air duct cover 512. The upper air duct shell 511 forms an upper air duct cavity with an opening facing the refrigeration room 31, and the upper air duct cover 512 covers the opening of the upper air duct cavity.

[0068] The upper air duct shell 511 is provided with a first upper slot 5111 and a first lower slot 5112. The first upper slot 5111 and the first lower slot 5112 are located at the top and bottom of the upper air duct shell 511, and the openings of the first upper slot 5111 and the first lower slot 5112 face the refrigeration chamber 31.

[0069] The upper air duct cover 512 is provided with an upper flange 5121 and a lower flange 5122. The upper flange 5121 and the lower flange 5122 are provided at the top and bottom of the upper air duct cover 512 and extend toward the upper air duct shell 511.

[0070] The upper flange 5121 and the lower flange 5122 are respectively disposed in the first upper slot 5111 and the first lower slot 5112, so that the upper air duct cover 512 is fixed to the upper air duct shell 511.

[0071] The bottom of the upper air duct housing 511 extends downward near the opening of the upper air duct cavity and is provided with a fixing slot 5113. The top of the first side wall 33 is located in the fixing slot 5113, so that the upper air duct 51 is fixed to the first side wall 33. Furthermore, the upper air duct cover plate 512 is flush with the first side wall 33.

[0072] like Figure 5 In the middle, the downwind duct 52 includes a downwind duct cover plate 521, an upper reinforcing strip 522, and a lower reinforcing strip 523.

[0073] The cross-section of the downdraft cover 521 is C-shaped, and both the upper reinforcing strip 522 and the lower reinforcing strip 523 are L-shaped.

[0074] The upper reinforcing strip 522 is fixed to the first side wall 33 on one side and has a second upper slot 5221 with an opening facing the refrigeration chamber 31 on the other side; the lower reinforcing strip 523 is fixed to the first side wall 33 on one side and has a second lower slot 5231 with an opening facing the refrigeration chamber 31 on the other side.

[0075] The upper and lower ends of the downdraft cover 521 are respectively inserted into the second upper slot 5221 and the second lower slot 5231, so that the downdraft cover 521 is fixed to the first side wall 33 and together with the first side wall 33 forms the downdraft cavity 52.

[0076] Both the upper air duct cover 512 and the lower air duct cover 521 are provided with snap-fit ​​holes near the air outlet. The air guide assembly 10 is fixed to the upper air duct cover 512 or the lower air duct cover 521 by the cooperation of the buckle 14 and the snap-fit ​​holes.

[0077] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0078] The detailed descriptions listed above are merely specific descriptions of feasible implementation methods of this application and are not intended to limit the scope of protection of this application.
