Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
The embodiment discloses refrigerator air duct component matching structure and refrigerator. As shown in fig. 3 to 13, the refrigerator air duct component matching structure comprises a tank liner 1 and an air return duct joint 2, wherein an air return duct hole 11 is formed in the tank liner 1, and a duct through hole 21 is formed in the middle of the air return duct joint 2. Align return air duct hole 11 with pipeline through-hole 21 during the installation, be provided with annular rib 3 on one of box courage 1 and return air duct joint 2 and connect 2, be provided with on the other with rib 3 matched with annular recess 4, rib 3 and recess 4's cooperation structure encircle in return air duct hole 11's periphery. In this embodiment, the rib 3 is disposed on the tank liner 1, and the groove 4 is disposed on the return duct joint 2.
The structure that the ribs 3 and the grooves 4 are buckled is arranged around the air return duct hole 11 in a circle, so that the air return duct has enough sealing performance under the condition that no adhesive tape is adhered, the use of a fixing adhesive tape and a leakage stoppage sponge is greatly reduced, foam leakage during foaming of a refrigerator can be effectively avoided, the operation is convenient, the assembly efficiency is improved, the production cost of products is reduced, and the waste of materials is reduced; the working procedures of cleaning the foam liquid are reduced, and the production efficiency and the product production quality are improved.
In order to improve the sealing performance of the rib 3 and the groove 4 after being buckled as much as possible, the rib 3 and the groove 4 are preferably designed to be in interference fit, and the inner wall of the groove 4 can extrude the outer wall of the rib 3 to a certain degree. When the surfaces of the groove 4 and the rib 3 are slightly uneven, the groove 4 can extrude the rib 3 to eliminate the gap between the groove 4 and the rib 3 caused by uneven surfaces, and the requirement on the processing precision is reduced.
The concrete structure of rib 3 is not limited, can realize with the structure of recess 4 looks lock can. Preferably, as shown in fig. 5, in the longitudinal section, the rib 3 includes two rib base surfaces 31, each rib base surface 31 connects to one rib vertical surface 32, a rib top surface 33 is connected between the two rib vertical surfaces 32, and a rounded corner surface 5 is formed between any two adjacent surfaces of the rib base surface 31, the rib vertical surface 32 and the rib top surface 33. In the transverse section, the rib 3 comprises at least four rib vertical surfaces 32 which are sequentially connected end to end, and a chamfer surface 5 is formed between any two adjacent rib vertical surfaces 32.
The arrangement of the chamfer face 5 is favorable for enhancing the strength of the ribs 3, and the plastic suction and the demolding are convenient. Furthermore, the included angle alpha between the vertical surfaces 32 of the ribs and the vertical surface is within 5-10 degrees, and the slope-shaped vertical surfaces 32 of the ribs are beneficial to plastic sucking and demolding; in addition, the slope-shaped structure increases the area of the rib vertical surface 32, so that the contact area between the rib 3 and the groove 4 is increased, the buckling structure of the rib 3 and the groove 4 is more stable, and the sealing performance is better.
Correspondingly, as shown in fig. 7 and 8, in the longitudinal section, the groove 4 includes two groove bases 41, each groove base 41 connects to one groove riser 42, a groove floor 43 is connected between the two groove risers 42, and a chamfer 5 is formed between any two adjacent grooves bases 41, 42 and 43. In the transverse section, the groove 4 comprises at least four groove vertical surfaces 42 which are sequentially connected end to end, and a chamfer surface 5 is formed between any two adjacent groove vertical surfaces 42.
The arrangement of the chamfer face 5 also helps to increase the strength of the groove 4, and is convenient for injection molding and demolding. Furthermore, the included angle beta between the vertical surface 42 of the groove and the vertical surface is within 5-10 degrees, and the slope-shaped vertical surface 42 of the groove is beneficial to injection molding and demolding; in addition, the slope-shaped structure increases the area of the groove vertical surface 42, so that the contact area between the rib vertical surface 32 and the groove vertical surface 42 is increased, the buckling structure of the rib 3 and the groove 4 is more stable, and the sealing performance is improved.
On the basis of the above structure, a layer of leakproof tape (not shown) is adhered to the outer edge of the return duct joint 2 to seal the parts outside the matching structure of the ribs 3 and the grooves 4. In the existing structure, in order to avoid bubble leakage, a plurality of adhesive tapes are required to be repeatedly and tightly pressed, when automatic gluing is adopted, glue around the box container is easily overflowed to the box container under the action of pressure to punch holes, and therefore the cold quantity transmission and the appearance quality of the refrigerator are influenced. Only need paste one deck leak protection sticky tape in return air duct joint 2's outside edge in this embodiment, when adopting sticky fixing, glue receives blockking of case courage rib 3 and overflows the outside of gluing to return air duct joint 2, can not overflow and glue to case courage towards hole department to can avoid influencing the refrigerator quality, be convenient for realize automatic assembly.
On the basis of the above structure, in consideration of the fact that a gap may be formed between the rib 3 and the groove 4 due to the problem of machining accuracy, and the gap may have a risk of bubble leakage, the sealing layer 6 may be provided between the rib 3 and the groove 4, and the gap may be filled with the sealing layer 6. Preferably, the sealing layer 6 is a sheet-like structure made of a flexible material, and during installation, the sealing layer 6 is firstly paved on the rib 3 or the groove 4, and then the groove 4 or the rib 3 is pressed on the sealing layer 6 until the rib 3 is buckled with the groove 4; or a proper amount of glue is dripped into the groove 4, the rib 3 is pressed into the groove 4, and the glue is condensed to form the sealing layer 6.
It should be noted that the foregoing is only a preferred embodiment of the present invention and the technical principles applied. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail with reference to the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the scope of the present invention.
