[0040] Combine the following Figures 1 to 6 The utility model describes an air duct cover plate and a refrigerator.

[0041] According to the air duct cover plate of the first embodiment of the utility model, Figure 1 , Figure 3 and Figure 5 As shown, the air duct cover includes a cover body 100 and a mounting member 200, wherein the mounting member 200 is connected to the cover body 100 and is suitable for mounting a sensor. The mounting member 200 is movably matched with the cover body 100 so that the mounting member 200 protrudes from the edge of the cover body 100.

[0042] According to the air duct cover plate of the embodiment of the utility model, when the sensor needs to be installed, the mounting member 200 is moved relative to the cover plate body 100 so that the mounting member 200 protrudes from the edge of the cover plate body 100, thereby making the installation position of the sensor on the mounting member 200 and the installation structure of the sensor protrude from the cover plate body 100, thereby effectively preventing the cover plate body 100 from blocking the installation position and the installation structure of the sensor, and further when the sensor is installed on the mounting member 200, the assembly status of the sensor on the mounting member 200 can be intuitively confirmed, thereby effectively ensuring the installation quality of the sensor on the air duct cover plate.

[0043] It can be understood that after the installation of the sensor is completed, the mounting member 200 can be moved toward the interior of the cover body 100 to fix the mounting member 200 inside the cover body 100, thereby hiding the mounting member 200 and the sensor inside the cover body 100, so that the sensor can detect the internal parameters of the cover body 100.

[0044] In one embodiment of the present invention, the mounting member 200 is rotatably connected to the cover body 100 so that the mounting member 200 can be switched between a deployed position and a shielding position, wherein in the shielding position, the sensor is located between the mounting member 200 and the cover body 100, and in the deployed position, the mounting member 200 protrudes from the edge of the cover body 100.

[0045] It is understandable that when the sensor needs to be installed, the mounting member 200 can be rotated relative to the cover body 100 to switch the mounting member 200 to the unfolded position, so that the mounting member 200 protrudes from the edge of the cover body 100, thereby facilitating the installation of the sensor. After the installation of the sensor is completed, the mounting member 200 is pushed to rotate relative to the cover body 100 to switch the mounting member 200 to the shielding position, thereby fixing the mounting member 200 inside the cover body 100. At this time, the sensor is located between the mounting member 200 and the cover body 100 to ensure that the sensor is hidden inside the cover body 100.

[0046] It should be noted that the movable connection between the mounting member 200 and the cover body 100 is not limited to a rotational connection, but may also be a sliding connection. Specifically, the cover body 100 is formed with a slide groove, and the mounting member 200 is formed with a boss, and the boss is slidably matched with the slide groove.

[0047] When the sensor needs to be installed, the boss on the mounting member 200 can be pushed to slide relative to the slide groove toward the outside of the edge of the cover body 100, so that the mounting member 200 protrudes from the edge of the cover body 100. After the sensor is installed, the boss on the mounting member 200 is pushed to slide toward the inside of the cover body 100, so that the mounting member 200 is stored inside the cover body 100.

[0048] In one embodiment of the present invention, Figure 2 and Figure 4 As shown, the mounting member 200 is provided with a rotating portion 210, and the cover body 100 is provided with a fixed portion 110. The rotating portion 210 and the fixed portion 110 are rotatably connected via a connecting portion, and the thickness of the rotating portion 210 and the thickness of the fixed portion 110 are both greater than the thickness of the third connecting portion.

[0049] It can be understood that by forming a rotating part 210 on the mounting member 200, forming a fixed part 110 on the cover body 100, and rotatably connecting the rotating part 210 and the fixed part 110 via a connecting part, the connecting part serves as a connecting part between the mounting member 200 and the cover body 100, and serves as a rotation axis of the mounting member 200 and the cover body 100, thereby realizing the rotation of the mounting member 200 relative to the cover body 100, so that the mounting member 200 can protrude from the edge of the cover body 100, or the mounting member 200 can be fixed to the inside of the cover body 100.

[0050] Since the thickness of the connecting portion is smaller than both the thickness of the rotating portion 210 and the thickness of the fixed portion 110, when the mounting member 200 rotates relative to the cover body 100, a yielding structure is formed between the rotating portion 210 and the fixed portion 110, so that there is a certain rotation space between the rotating portion 210 and the fixed portion 110 during the rotation process, thereby effectively avoiding interference between the rotating portion 210 and the fixed portion 110 and reducing stress concentration between the rotating portion 210 and the fixed portion 110.

[0051] Exemplarily, the rotating portion 210 is a boss structure formed on the mounting member 200, the fixing portion 110 is a rib structure formed on the outer edge of the cover body 100, the connecting portion is a connecting beam structure formed between the cover body 100 and the mounting member 200, and the mounting member 200 and the cover body 100 are integrally formed of a plastic material with good toughness and impact resistance. When the mounting member 200 protrudes from the edge of the cover body 100, the cross-sectional area of ​​the rotating portion 210 gradually decreases along the direction of the mounting member 200 toward the cover body 100, and the cross-sectional area of ​​the fixing portion 110 gradually increases along the direction of the mounting member 200 toward the cover body 100, so that the thickness of the connecting portion of the rotating portion 210 and the fixing portion 110 is minimized, so that the mounting member 200 can rotate relative to the cover body 100.

[0052] Furthermore, when the mounting member 200 is not subjected to external force, the shapes and positions of the mounting member 200 and the cover body 100 are kept fixed under the cooperation of the fixing portion 110, the connecting portion and the rotating portion 210. When the mounting member 200 is subjected to external force directed to the inside of the cover body 100, the mounting member 200 is turned over to the inside of the cover body 100 under the action of the external force, so as to fix the mounting member 200 to the inside of the cover body 100. At this time, the connection between the cover body 100 and the mounting member 200 is maintained under the action of the connecting portion.

[0053] It should be noted that the processing material of the cover body 100 and the mounting member 200 is preferably high impact polystyrene (HIPS), and the connection between the cover body 100 and the mounting member 200 is maintained by utilizing the good toughness and impact resistance of HIPS.

[0054] It should also be noted that the cover body 100 and the mounting member 200 can also be connected via a hinge structure, wherein the rotating portion 210 is one of the rotating pages of the hinge structure, and the mounting member 200 is connected to one of the rotating pages; the fixed portion 110 is another rotating page of the hinge structure, and the cover body 100 is connected to the other rotating page; a rotating shaft is formed between the two rotating pages to facilitate the rotation of one rotating page relative to the other rotating page. Furthermore, by driving one of the rotating pages to rotate relative to the other rotating page, the mounting member 200 can be driven to rotate relative to the cover body 100, thereby making the mounting member 200 protrude from the edge of the cover body 100, or rotating the mounting member 200 to the inside of the cover body 100.

[0055] Of course, the cover body 100 and the mounting member 200 are not limited to being connected by a hinge structure. A through hole may be formed on the mounting member 200, and a boss may be provided on the cover body 100 with a through hole formed on the boss. The mounting member 200 and the cover body 100 may be rotatably connected by a rotating shaft.

[0056] In one embodiment of the present invention, Figure 2 , Figure 4 and Figure 6 As shown, the cover body 100 is provided with a first fixing member 120 , and the first fixing member 120 is detachably connected to the mounting member 200 , and the mounting member 200 is suitable for being fixed to the inside of the cover body 100 through the first fixing member 120 .

[0057] It is understandable that when the mounting member 200 rotates toward the inside of the cover body 100, the first fixing member 120 is connected to the mounting member 200, so that the mounting member 200 is fixed to the inside of the cover body 100 through the first fixing member 120, so as to achieve hiding of the mounting member 200 and the sensor inside the cover body 100. Since the first fixing member 120 and the mounting member 200 are detachably connected, when the mounting member 200 needs to be protruded from the cover body 100, the connection between the first fixing member 120 and the mounting member 200 can be disconnected, so as to facilitate the rotation of the mounting member 200 relative to the cover body 100, so as to achieve protrusion of the mounting member 200 from the cover body 100.

[0058] Exemplarily, in this embodiment, the first fixing member 120 is an elastic snap-fit ​​structure, and a step surface is provided on the side of the elastic snap-fit ​​facing the first fixing member 120, the step surface faces the bottom surface of the cover body 100, and the step surface protrudes from the side of the elastic snap-fit ​​facing the first fixing member 120.

[0059] When the mounting member 200 is turned over to the inside of the cover body 100, the elastic buckle is lightly pressed in the direction away from the first fixing member 120, so that the mounting member 200 can be turned over to between the step surface of the elastic buckle and the wall surface of the cover body 100. After the elastic buckle is released, the elastic buckle rebounds, and the step surface of the elastic buckle abuts against the side of the mounting member 200 away from the inside of the cover body 100, so that the mounting member 200 is pressed against the step surface of the elastic buckle, and the mounting member 200 is fixed inside the cover body 100.

[0060] For example, the first fixing member 120 may also be a convex column structure or a boss structure formed on the cover body 100, and a countersunk hole is formed on the convex column structure or the boss structure. One end of the spring is connected to the inner wall surface of the countersunk hole, and the other end of the spring is connected to a limiter, which is inserted into the countersunk hole. The limiter may be a boss structure, and a contact plane is formed on the side of the limiter facing the cover body 100.

[0061] When it is necessary to fix the mounting member 200 by the first fixing member 120, the limit member can be pressed so that the limit member compresses the spring, causing the mounting member 200 to flip to between the abutment plane of the limit member and the wall surface of the cover body 100, and then the limit member is released. Under the action of the spring elastic force, the abutment platform of the limit member protrudes out of the countersunk hole and abuts against the mounting member 200, thereby fixing the mounting member 200 inside the cover body 100.

[0062] It should be noted here that, in addition to the above-mentioned setting method, the first fixing member 120 can also be other fixing structures that can fix the mounting member 200 inside the cover body 100, and can be set according to actual needs.

[0063] In an embodiment of the present invention, the first fixing member 120 is a buckle structure, the mounting member 200 is formed with a buckle hole 220 , and the buckle structure is buckled with the buckle hole 220 .

[0064] It can be understood that when the mounting member 200 is fixed inside the cover body 100, the snap-fit ​​cooperation between the snap-fit ​​structure and the snap-fit ​​hole 220 can improve the connection stability between the mounting member 200 and the first fixing member 120 and avoid the rebound of the mounting member 200. At the same time, the snap-fit ​​structure can also be used to position the snap-fit ​​hole 220 on the mounting member 200, so that the mounting member 200 can be quickly fixed inside the cover body 100, thereby improving the speed of fixing the mounting member 200 and ensuring the efficiency of installing the sensor inside the cover body 100.

[0065] Exemplarily, the first fixing member 120 is an elastic buckle.

[0066] It should be noted here that the protruding portion of the buckle structure is away from the second connecting portion.

[0067] In one embodiment of the present invention, Figure 2 , Figure 4 and Figure 6 As shown, a first guiding slope 121 is provided on the side of the first fixing member 120 facing away from the cover body. When the mounting member 200 is turned over to the inside of the cover body 100, the mounting member 200 contacts the guiding slope, and under the action of the first guiding slope 121, the first fixing member can be more conveniently inserted into the clamping hole 220, and the time for the mounting member 200 to press the first fixing member 120 is reduced, so as to reduce the deformation of the first fixing member 120, so as to prevent the first fixing member 120 from being worn and deformed and losing the fixing effect.

[0068] Furthermore, if Figure 4 As shown, the engaging hole 220 is provided with a second guiding inclined surface 221 , and the inclined direction of the second guiding inclined surface 221 is the same as the inclined direction of the first guiding inclined surface 121 .

[0069] It is understandable that by forming a second guide bevel 221 on the snap-in hole 220 and by the abutment between the second guide bevel 221 and the first guide bevel 121, the time for the mounting member 200 to press the first fixing member 120 can be further reduced, thereby further reducing the deformation of the first fixing member 120.

[0070] In one embodiment of the present invention, Figure 2 and Figure 4 As shown, the mounting member 200 includes a connecting plate 230 and a mounting groove 240. The connecting plate 230 is rotatably connected to the cover body 100, and the mounting groove 240 is disposed on the connecting plate 230, and the mounting groove 240 is used to fix the sensor.

[0071] It is understandable that by forming the mounting groove 240 on the connecting plate 230, a mounting structure of the sensor is formed in the connecting plate 230, and the sensor can be fixed through the mounting groove 240 to achieve the installation of the sensor. By rotating the connecting plate 230 relative to the cover body 100, the mounting member 200 is effectively protruded from the edge of the cover body 100, so that the mounting groove 240 can protrude from the cover body 100, so that the assembly state of the sensor in the mounting groove 240 can be visually confirmed, thereby ensuring the installation quality of the sensor.

[0072] It should be noted here that the snap-in hole 220 is formed on the connecting plate 230 , and the snap-in hole 220 can be driven to rotate by rotating the connecting plate 230 , so that the snap-in hole 220 can be matched and connected with the first fixing member 120 , thereby fixing the mounting member 200 inside the cover body 100 .

[0073] Furthermore, if Figure 2 and Figure 4As shown, the installation slot 240 is provided with a second fixing member 241 , and the second fixing member 241 abuts against the sensor to fix the sensor to the installation slot 240 .

[0074] It can be understood that the second fixing member 241 is an elastic snap-fit ​​structure. After the sensor is installed, the second fixing member 241 is used to limit the sensor to prevent the sensor from popping out of the installation slot 240, thereby fixing the sensor.

[0075] Exemplarily, the second fixing members 241 may be formed in plurality, and the plurality of second fixing members 241 are disposed around the side wall of the installation groove 240 , and the sensor is limited by the second fixing members 241 , thereby improving the stability of the sensor in the installation groove 240 .

[0076] It should be noted here that Figure 6 As shown, an avoidance hole 242 is formed at the bottom of the installation groove 240, and the sensor can pass through the avoidance hole 242 to contact the back space of the air duct cover plate, so that the sensor can detect relevant parameters of the back space of the air duct cover plate, thereby improving the detection accuracy of the sensor.

[0077] According to the embodiment of the second aspect of the utility model, the refrigerator includes the above-mentioned air duct cover plate, and thus has all the beneficial effects of the above-mentioned air duct cover plate, which will not be repeated here.

[0078] According to a refrigerator of one embodiment of the utility model, when installing the sensor of the air duct cover, the installation groove 240 in the installation member 200 protrudes from the cover body 100, and the sensor is fixed by the installation groove 240 and the second fixing member 241 to achieve the installation of the sensor. After the sensor is installed, the connecting plate 230 is turned toward the inside of the cover body 100 through the rotating part 210, and the mounting member 200 is fixed to the inside of the cover body 100 through the snap structure formed on the cover body 100 and the snap hole 220 formed on the installation member 200, so that the sensor is hidden inside the cover body 100, so that the sensor can detect the internal parameters of the cover body 100.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
