Background technique

At present, air-cooled refrigerators are the most common type of refrigerators. Air-cooled refrigerators usually use duct structures to transport cold air for refrigeration. The structure of the duct largely determines the overall air supply efficiency of the duct. It is particularly important that the duct structure has excellent sealing properties, otherwise frost and ice will form, causing damage to the duct and affecting the refrigeration effect of the refrigerator.

The related technology is to seal the damper sealing strips at the upper and lower ends of the damper first, then install the damper into the air duct foam along a certain direction, and finally seal the damper with the foam back cover. The sealing strip is arranged between the damper and the air duct foam, which plays a role in sealing the air duct structure.

In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

Although the sealing method in the related technology can seal the air duct structure to a certain extent, as the user's usage time increases, the air duct structure will age after long-term load, and the sealing strip will deform. The generated reverse force will cause the sealing strip to deform in the up and down directions, causing the foam back cover to bulge, and the air leakage gap in the air duct will become larger, affecting the cooling effect.

It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

At present, air-cooled refrigerators are the most common type of refrigerators. Air-cooled refrigerators usually use duct structures to transport cold air for refrigeration. The structure of the duct largely determines the overall air supply efficiency of the duct. It is particularly important that the duct structure has excellent sealing properties, otherwise frost and ice will form, causing damage to the duct and affecting the refrigeration effect of the refrigerator.

The related technology is to seal the damper sealing strips at the upper and lower ends of the damper first, then install the damper into the air duct foam along a certain direction, and finally seal the damper with the foam back cover. The sealing strip is arranged between the damper and the air duct foam, which plays a role in sealing the air duct structure.

Although the sealing method in the related technology can seal the air duct structure to a certain extent, as the user's usage time increases, the air duct structure will age after long-term load. The reverse force generated by the sealing strip will cause the sealing strip to deform in the up and down directions, causing the duct foam back cover to bulge and the air leakage gap in the duct to become larger, affecting the cooling effect.

With reference to FIG. 1 , FIG. 2 a - FIG. 2 c , FIG. 3 a - FIG. 3 b and FIG. 4 , an embodiment of the present disclosure provides an air duct cover plate assembly.

The air duct cover plate assembly comprises an air duct plate 1 , an air door 2 , an air door fixing member 3 and an air door sealing strip 4 .

The refrigerator includes an inner tank and a refrigeration system. The inner tank defines a refrigeration space, and the air duct plate is arranged in the inner tank, and defines an air duct together with the inner tank. The air duct plate 1 is provided with an air inlet 11, and the air inlet 11 is connected to the air duct. The refrigeration system includes a compressor, a condenser and an evaporator connected to each other. The refrigerator also includes an evaporating fan, which corresponds to the evaporator and is used to drive the air in the refrigeration space from the air inlet into the air duct, and after heat exchange with the evaporator, it flows back to the refrigeration space, thereby realizing a refrigeration cycle of the refrigeration space.

As shown in Figures 1 and 2b, the air duct plate 1 is provided with an air inlet 11; the damper 2 is provided at the air inlet 11; the damper fixing member 3 includes a front side limiting plate 31, the front side limiting plate 31 is provided on the front wall 21 of the damper 2, and the front side limiting plate 31 and the damper 2 are arranged in sequence along the wind direction; the damper sealing strip 4 is provided between the front wall 21 of the damper 2 and the front side limiting plate 31, and is used for sealing between the front wall 21 of the damper 2 and the front side limiting plate 31.

Along the wind direction, the front side limit plate 31 of the damper fixing part 3, the damper sealing strip 4 and the damper 2 are arranged in sequence. When wind passes through the air inlet 11, the wind exerts a force on the front side limit plate 31 toward the damper sealing strip 4. The front side limit plate 31 squeezes the damper sealing strip 4. The damper sealing strip 4 exerts a force on the front side limit plate 31 away from the wind direction, and exerts a force on the damper 2 in the wind direction. Since the force exerted on the damper sealing strip 4 is along the wind direction, even if the damper sealing strip 4 has a slight deformation, it will not affect the sealing of the air duct assembly, and will not cause deformation in the up and down directions like the traditional air duct structure. Therefore, the present application can enhance the sealing of the air duct assembly.

Optionally, as shown in FIG. 1 , the damper 2 is provided with a vent 211 , the damper sealing strip 4 is circumferentially arranged around the vent 211 , and the front limiting plate 31 is provided with an opening 311 corresponding to the vent 211 .

When wind passes through the vent 211 of the damper 2 and the opening 311 of the front side limit plate 31, the damper sealing strip 4 is squeezed between the front side limit plate 31 and the front wall 21 of the damper 2, and the damper sealing strip 4 in the air duct structure of the related art will not deform in the up and down direction, and will only generate reaction force in the wind direction or away from the wind direction. The reaction force in the wind direction will be limited by the front wall 21 of the damper 2, and the reaction force away from the wind direction will be limited by the front side limit plate 31. Therefore, the damper sealing strip 4 is limited by the front wall 21 of the damper 2 and the front side limit plate 31, and basically will not deform, ensuring good sealing of the air duct cover assembly.

Optionally, as shown in FIGS. 1 and 2c, there are multiple dampers 2, the multiple dampers 2 include a first damper 22 and a second damper 23, and the air duct cover assembly further includes a connecting portion 24 and a first connecting portion sealing strip 241. The connecting portion 24 is connected between the first damper 22 and the second damper 23; the first connecting portion sealing strip 241 is provided between the connecting portion 24 and the air duct plate 1, and is used for sealing between the connecting portion 24 and the air duct plate 1.

The double damper 2 structure includes a first damper 22 and a second damper 23. The damper 2 is provided with a vent 211. The two dampers 2 differ only in the size of the vent 211, and the coordination arrangement of the damper sealing strip 4, the damper fixing member 3 and the air duct plate 1 is the same.

A connecting portion 24 is provided between the first damper 22 and the second damper 23. The sealing between the connecting portion 24 and the air duct plate 1 is sealed by a first connecting portion sealing strip 241, so that the sealing between the connecting portion 24 and the air duct plate 1 is enhanced to prevent cross-wind phenomenon between the first damper 22 and the second damper 23.

Optionally, as shown in FIG. 3 a and FIG. 3 b , the air duct plate 1 is provided with a groove 12 , and the connecting portion 24 is located in the groove 12 and confined in the groove 12 .

The groove 12 provided on the air duct plate 1 has a position limiting function for the connecting portion 24 of the damper 2 , thereby limiting the position of the damper 2 and restricting the damper 2 between the air duct plate 1 and the damper fixing member 3 .

Optionally, the damper fixing member 3 further includes a circumferential limit plate 32 , which is connected to the front limit plate 31 and the front limit plate 31 and the circumferential limit plate 32 are arranged in sequence along the wind direction, and the circumferential limit plate 32 is sleeved on the outer side of the damper 2 .

The damper sealing strip 4 may also be disposed between the circumferential limit plate 32 and the damper 2 to seal between the circumferential limit plate 32 and the damper 2 .

The damper sealing strip 4 is annular and is sleeved on the outside of the damper 2. The circumferential limit plate 32 is sleeved on the outside of the damper sealing strip 4. When the damper sealing strip 4 tends to deform in the upward and downward directions, the circumferential limit plate 32 and the damper 2 will simultaneously give the damper sealing strip 4 a limiting effect on the circumference of the damper sealing strip 4, so that the deformation of the damper sealing strip 4 is reduced, and the circumferential limit plate 32 cannot be driven to deform or shift. In this way, the damper sealing strip 4 will not deform as in the related art, thereby ensuring the good sealing performance of the air duct cover assembly.

Optionally, as shown in FIG. 3 a and FIG. 3 b , a step 13 is provided on the side wall of the groove 12 , and a portion of the circumferential limit plate 32 is located at the step 13 and abuts against the step 13 to limit the movement of the circumferential limit plate 32 in the wind direction.

Optionally, the groove wall of the groove 12 includes a groove bottom wall 121, and the connecting portion 24 and the groove bottom wall 121 are sequentially arranged along the airflow direction, and the connecting portion 24 abuts against the groove bottom wall 121 to limit the movement of the connecting portion 24 toward the airflow direction.

The connecting portion 24 abuts against the bottom wall 121 of the groove 12. When wind passes through the damper 2, the damper 2 tends to move in the wind direction. The bottom wall 121 of the groove 12 limits the position of the connecting portion 24, so that the damper 2 will not move in the wind direction.

Optionally, as shown in Fig. 3a and Fig. 3b, the groove wall of the groove 12 includes a groove bottom wall 121, and the air duct cover assembly further includes a first protrusion 122 and a second protrusion 123. The first protrusion 122 is protruded from the groove bottom wall 121; the second protrusion 123 is protruded from the groove bottom wall 121 and is arranged opposite to the first protrusion 122, and the connecting portion 24 is limited between the first protrusion 122 and the second protrusion 123.

The first protrusion 122 and the second protrusion 123 are arranged opposite to each other, and both are arranged protrudingly on the groove bottom wall 121 of the groove 12. The side wall of the groove 12 includes a first side wall and a second side wall. The first side wall is located on the side of the first protrusion 122 facing the inside of the groove 12, and the second side wall is located on the side of the second protrusion 123 facing the inside of the groove 12. The side of the connecting portion 24 close to the first protrusion 122 abuts against the first side wall, and the side of the connecting portion 24 close to the second protrusion 123 abuts against the second side wall. The first protrusion 122 and the second protrusion 123 play a role in limiting the connecting portion 24, and cooperate with the groove bottom wall 121 of the groove 12 to limit the connecting portion 24 in the groove 12 to limit the movement of the connecting portion 24. Due to the arrangement of the first protrusion 122 and the second protrusion 123, the sealing between the connecting portion 24 and the air duct plate 1 is enhanced, so that the possibility of wind flow between the first damper 22 and the second damper 23 is reduced.

Optionally, a step 13 is provided on the surface of the first protrusion 122 and/or the second protrusion 123 facing the damper fixing member 3, and a portion of the damper fixing member 3 is located on the step 13 to limit the damper fixing member 3 from moving in the airflow direction.

The number of steps 13 is at least one, only the surface of the first protrusion 122 facing the damper fixing member 3 is provided with a step 13, or only the surface of the second protrusion 123 facing the damper fixing member 3 is provided with a step 13, or both the surfaces of the first protrusion 122 and the second protrusion 123 facing the damper fixing member 3 are provided with steps 13.

The circumferential limit plate 32 of the damper fixing member 3 is partially located on the step 13 , and the step 13 serves to limit the position of the circumferential limit plate 32 , thereby limiting the movement of the circumferential limit plate 32 along the wind direction.

Optionally, as shown in Figure 2c, the air duct cover assembly also includes a second connecting portion sealing strip 242, which is arranged between the connecting portion 24 and the damper fixing member 3, and the second connecting portion sealing strip 242, the damper fixing member 3 and the connecting portion 24 are independent components for sealing between the connecting portion 24 and the damper fixing member 3.

The second connection part sealing strip 242 can be connected to the first connection part sealing strip 241 to form a ring, and together are arranged circumferentially around the connection part 24, or it can be two independent sealing strips, which are separately arranged, respectively arranged between the connection part 24 and the air duct plate 1 and the connection part 24 and the circumferential limit plate 32, to enhance the sealing between the damper fixing part 3 and the connection part 24, and prevent the occurrence of cross-wind phenomenon between the first damper 22 and the second damper 23.

Optionally, as shown in FIG. 2b , the air duct cover assembly further includes a sealing protrusion 25, which can be formed by the damper fixing member 3 protruding toward the connecting portion 24. In this case, the sealing protrusion 25 and the damper fixing member 3 are an integrated structure, and the sealing protrusion 25 abuts against the connecting portion 24. Alternatively, the sealing protrusion 25 can be formed by the connecting portion 24 protruding toward the damper fixing member 3, the sealing protrusion 25 and the connecting portion 24 are an integrated structure, and the sealing protrusion 25 abuts against the damper fixing member 3.

When the damper fixing piece 3 protrudes toward the connecting portion 24, a sealing protrusion 25 is formed, and the sealing protrusion 25 abuts against the connecting portion 24, so that no space is left between the damper fixing piece 3 and the connecting portion 24, it cooperates with the second connecting portion sealing strip 242 to enhance the sealing between the damper fixing piece 3 and the connecting portion 24, and prevents the occurrence of wind cross-flow between the first damper 22 and the second damper 23.

When the connecting portion 24 protrudes toward the damper fixing member 3 to form a sealing protrusion 25, and the sealing protrusion 25 abuts against the damper fixing member 3, so that no space is left between the damper fixing member 3 and the connecting portion 24, it cooperates with the second connecting portion sealing strip 242 to enhance the sealing between the damper fixing member 3 and the connecting portion 24, and prevents the occurrence of wind cross-flow between the first damper 22 and the second damper 23.

Optionally, as shown in FIG. 4 , the air duct plate 1 is provided with a mounting groove 14 , and the damper fixing member 3 , the damper sealing strip 4 and the damper 2 are arranged in the mounting groove 14 of the air duct plate 1 .

The damper fixing member 3, damper sealing strip 4 and damper 2 are installed in the installation groove 14 of the air duct plate 1. The air duct plate 1 limits the position of the damper fixing member 3, damper sealing strip 4 and damper 2. When wind passes through the damper 2, the whole will not move relative to the air duct plate 1, ensuring normal ventilation and improving ventilation efficiency. In addition, the installation groove 14 also plays a certain sealing role between the air duct plate 1 and the damper fixing member 3.

Optionally, the width of the gap between the front wall 21 of the damper 2 and the front limiting plate 31 is smaller than the thickness of the damper sealing strip 4 .

After the damper sealing strip 4 is installed between the front wall 21 of the damper 2 and the front side limiting plate 31, due to the difference in thickness, it will be squeezed by the front wall 21 and the front side limiting plate 31, so that the sealing between the damper 2 and the damper fixing member 3 is enhanced, and the front wall 21 and the front side limiting plate 31 limit the damper sealing strip 4 to prevent the damper sealing strip 4 from deformation, which also enhances the sealing between the damper 2 and the damper fixing member 3.
