DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0033] At present, an air outlet is opened on the air duct mask of a refrigerator, and a wind shield structure is arranged on the air duct mask. The wind shield structure can change the situation of blocking the air outlet. If there is a gap between the wind shield structure and the air duct mask, air leakage will occur, and eventually the temperature in the refrigerator room may not reach the required range. Based on this, the present invention provides a wind shield adjustment mechanism, which includes a dial 1 and an elastic locking component 2, wherein the elastic locking component 2 is connected to the air duct mask 3 provided with the air outlet 31, and the dial 1 is squeezed on the air duct mask 3 by the elastic locking component 2. Under the squeezing of the elastic locking component 2, the dial 1 fits the air duct mask 3 to avoid the situation of air leakage caused by the gap between the dial 1 and the air duct mask 3. Pushing the dial 1 fitted on the air duct mask 3 can change the opening state of the air outlet 31, that is, adjusting the position of the dial 1 can open and close the air outlet 31.

[0034] As an optional implementation, the elastic locking component 2 and the shifter 1 are preferably connected in a rolling manner to reduce the resistance of the elastic locking component 2 to the shifter 1 when the shifter 1 moves, thereby achieving a locking effect and ensuring that the shifter 1 can move smoothly.

[0035] Regarding the elastic locking component 2, the specific structure can be as follows: the elastic locking component 2 includes a frame 21, an elastic member 22 and a ball 23, the frame 21 is connected to the air duct mask 3, a placement groove is provided on the frame 21, the ball 23 and the elastic member 22 are located in the placement groove, the ball 23 protrudes from the bottom of the frame 21 and presses the elastic member 22 when the ball 23 moves toward the inside of the frame 21. Figure 4 and Figure 5, schematically shows the elastic locking component 2, the elastic component 22 is preferably a spring, when the elastic locking component 2 is fixed to the air duct mask 3, the elastic component 22 is in a compressed state, and the shift lever 1 is pressed against the air duct mask 3 through the elastic component 22 and the ball 23. When the shift lever 1 is pushed, the ball 23 rolls, realizing a rolling connection between the elastic locking component 2 and the shift lever 1.

[0036] As an optional embodiment, the frame 21 is detachably connected to the air duct mask 3 by snap-fitting. The snap-fitting connection is simple, and the removable connection between the elastic locking component 2 and the air duct mask 3 is achieved by snap-fitting. When the elastic locking component 2 is removed from the air duct mask 3, the squeezing of the shift lever 1 can be released, so that the shift lever 1 can be removed from the air duct mask 3, which is convenient for replacing the shift lever 1. The specific snap-fitting structure between the frame 21 and the air duct mask 3 is as follows: the frame 21 is made of plastic material, and an elastic buckle 24 is provided on the frame 21. The two elastic buckles 24 are symmetrically distributed on the left and right sides of the frame 21. A mounting plate 4 is provided on the air duct mask 3, and an assembly hole is provided on the mounting plate 4. The elastic locking component 2 is inserted into the assembly hole, and the elastic buckle 24 contacts the side of the mounting plate 4 facing the shift lever 1. See FIG. Figure 4 , showing an L-shaped mounting plate 4, the elastic locking member 2 is inserted into the assembly hole on the mounting plate 4 and clamped on the mounting plate 4, and the shifter 1 is squeezed between the air duct mask 3 and the ball 23; see Figure 5 , which shows a cross-sectional view of the elastic locking component 2. When the elastic locking component 2 is installed on the mounting plate 4, the elastic locking component 2 is first inserted into the assembly hole. When the elastic buckle 24 is inserted into the assembly hole, the elastic buckle 24 is forced to move inward. After the elastic buckle 24 passes through the assembly hole, the elastic buckle 24 is reset. The elastic buckle 24 contacts the side of the mounting plate 4 facing the shifter 1, so that the frame 21 will not be ejected from the mounting plate 4 under the action of the elastic member 22. When it is necessary to remove the elastic locking component 2 from the air duct mask 3, a force is applied to the elastic buckle 24 so that the elastic buckle 24 is forced to move inward until the frame 21 is ejected outward under the action of the elastic member 22, so that the elastic locking component 2 is separated from the mounting plate 4.

[0037] Regarding the distribution of the elastic locking components 2, mounting plates 4 are disposed on opposite sides of the shifter 1, and an elastic locking component 2 is disposed on each mounting plate 4. Figure 2 , illustrating that two mounting plates 4 are arranged above the shift lever 1, and one mounting plate 4 is arranged below the shift lever 1, and an elastic locking component 2 is arranged on each mounting plate 4, and the shift lever 1 is clamped on the air duct mask 3 by three elastic locking components 2. Of course, the number of the elastic locking components 2 is not limited to three.

[0038] Regarding the mounting plate 4, the specific description is as follows: the mounting plate 4 is L-shaped, the vertical portion of the mounting plate 4 is connected to the air duct mask 3, the transverse portion of the mounting plate 4 is connected to the vertical portion and is parallel to the shift lever 1, the transverse portion is located above the shift lever 1 and the elastic locking component 2 is arranged on the transverse portion. When the elastic locking component 2 is removed from the transverse portion, the shift lever 1 is pushed out on one side to detach from the mounting plate 4, thereby realizing the removal of the shift lever 1 from the air duct mask 3.

[0039] As an optional embodiment, a guide groove 11 is provided on the side of the shift lever 1 facing away from the air duct mask 3, the length extension direction of the guide groove 11 is parallel to the moving direction of the shift lever 1, the bottom of the elastic locking component 2 is located in the guide groove 11, and the guide groove 11 cooperates with the elastic locking component 2 to form a guide structure. Figure 2 , showing the guide groove 11, see Figure 4 , which illustrates that the ball 23 of the elastic locking component 2 is located in the guide groove 11. When the shift lever 1 is pushed, the ball 23 rolls in the guide groove 11 to guide the moving direction of the shift lever 1.

[0040] As an optional implementation, the shifter 1 is provided with an elastic rib 12, and the air duct mask 3 is provided with a matching groove, and there are more than two matching grooves. Pushing the shifter 1 can make the elastic rib 12 be located in different matching grooves so that the shifter 1 forms different gears. Figure 2 , taking the three matching grooves set on the air duct mask 3 as an example, the three matching grooves are spaced in sequence along the moving direction of the shift lever 1. When the air outlet 31 is in a fully open state, the elastic convex rib 12 is located in the matching groove on the far left, and the shift lever position at this time is that the air outlet is fully opened; the shift lever 1 is lifted to the right, so that the shift lever 1 is disengaged from the matching groove on the far left and moves to the right, until the elastic convex rib 12 is located in the matching groove in the middle position, and the shift lever position at this time is that the air outlet is partially opened, and the shift lever 1 is continued to be pushed to the right, so that the shift lever 1 is disengaged from the matching groove in the middle and moves to the right, until the elastic convex rib 12 is located in the matching groove on the far right, and the shift lever position at this time is that the air outlet is completely closed.

[0041] The connection between the elastic rib 12 and the shifter 1 is as follows: the shifter 1 is provided with a horizontal U-shaped groove 13, see Figure 6 , showing a U-shaped groove 13, the area of ​​the shift lever 1 located in the U-shaped groove 13 forms an elastic sheet 14, and an elastic rib 12 is provided on the side of the elastic sheet 14 that fits the air duct mask 3, and the elastic rib 12 is close to the free end of the elastic sheet 14. The shift lever 1 is made of plastic material, and when the elastic rib 12 contacts the air duct mask 3, the elastic sheet 14 is elastically deformed, and when the elastic rib 12 is located in the matching groove, the elastic sheet 14 is in the original undeformed state.

[0042] In addition, regarding the specific structure of the elastic buckle 24, the existing buckle structure can be adopted, or the structural principle of the elastic buckle 24 can be the same as the elastic rib 12 and the connection structure between the elastic rib 12 and the shifter 1.

[0043] As an alternative embodiment, see Figure 2 and Figure 6 , schematically showing the shape of the shifter 1, the shifter 1 includes a main body 15, a first side portion 16 and a second side portion 17, the first side portion 16 and the second side portion 17 are respectively arranged on the left and right sides of the main body 15 and are both connected to the main body 15, a matching air outlet 18 is arranged on the first side portion 16, and two air outlets 31 are arranged on the air duct mask 3, see Figure 2 When the matching air outlet 18 is connected to one of the air outlets 31 so that the air outlet 31 is in a fully open state, the second side portion 7 is located on one side of the other air outlet 31. The two air outlets 31 are in a fully open state, a fully closed state, and a half-open state at the same time. Figure 2 When the shift lever 1 moves to the right until the second side portion 17 completely blocks the air outlet 31 on the right side, the area on the first side portion 16 located on the left side of the matching air outlet 18 blocks the air outlet 31 .

[0044] A guide strip 3 is provided on the air duct mask 3, and each of the first side portion 16 and the second side portion 17 corresponds to a pair of guide strips 5, and the first side portion 16 and the second side portion 17 are respectively sandwiched between the two matching guide strips 5, see Figure 2 , the guide bar 5 is shown, which not only guides the movement of the shift lever 1, but also limits the range of movement of the shift lever 1 on the air duct mask 3 through the contact between the guide bar 3 and the side of the main body 15, so as to avoid the shift lever 1 from being separated from the air duct mask 3 when moving the shift lever 1. Here, it should be noted that, see Figure 2 When the guide strip 3 is provided on the duct mask 3, the height of the guide strip 3 protruding from the duct mask 3 is less than the distance between the lateral portion of the mounting plate 4 and the duct mask 3. If the shift lever 1 is to be removed, the elastic locking component 2 is first removed from the lateral portion, and then the shift lever 1 is moved away from the duct mask 3 until the guide strip 5 cannot limit the position of the shift lever 1 when the shift lever 1 is moved horizontally to the left or rear side.

[0045] As an alternative embodiment, see Figure 6 A hand-pushing rib 19 is provided on the side where the shift lever 1 is in contact with the air duct mask 3, and a matching hole is provided on the air duct mask 3. The hand-pushing rib 19 is inserted into the matching hole and protrudes out of the air duct mask 3. When the position of the shift lever 1 needs to be adjusted, the user can apply force to the hand-pushing rib 19 to move the shift lever 1 to change the blocked state of the air outlet 1.

[0046] A refrigerator includes an air duct mask 3 and a windshield adjustment mechanism provided by the present invention. The windshield adjustment mechanism includes a shift lever 1 and an elastic locking component 2. The shift lever 1 fits the air duct mask 3 under the pressure of the elastic locking component 2 to avoid air leakage caused by a gap between the shift lever 1 and the air duct mask 3.

[0047] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
