An aspect of an embodiment of the present invention provides a refrigerator.
Fig. 1 is a partial structural schematic view of a refrigerator according to an embodiment of the present invention; fig. 2 is an exploded view of the liner 12 and the air duct member 30 of the structure shown in fig. 1.
As shown in fig. 1 and 2, a refrigerator according to an embodiment of the present invention may generally include a cabinet 10 and a duct member 30.
The case 10 defines a storage compartment 128 for storing food or other items. Specifically, the case 10 may include an outer case (not shown) and an inner container 12. The liner 12 is disposed inside the housing. A foam layer is provided between the outer shell and the inner liner 12. The exterior of the housing forms the exterior of the refrigerator and the liner 12 defines a storage compartment 128.
The storage compartment may be divided into a refrigerating compartment, a freezing compartment, a temperature changing compartment, etc., according to the difference of storage temperatures. The temperature ranges within the various types of storage compartments are different. For example, the temperature in the refrigeration compartment is generally controlled between 2 ℃ and 10 ℃, preferably between 4 ℃ and 7 ℃. The temperature in the freezer compartment is typically controlled in the range of-22 ℃ to-14 ℃. The temperature changing chamber can be adjusted between-18 ℃ and 8 ℃ to realize the temperature changing effect. The optimal storage temperatures of different kinds of articles are different, and the storage compartments suitable for storage are also different. For example, fruit and vegetable foods are suitably stored in the refrigerating chamber, and meat foods are suitably stored in the freezing chamber. Each storage compartment is provided with a door or drawer (not shown) for opening and closing the storage compartment.
In some embodiments, the refrigerator may use a vapor compression refrigeration cycle to cool to produce cool air. Vapor compression refrigeration cycle systems include compressors, condensers, evaporators, throttling devices, and other refrigeration fittings.
The air duct member 30 is an air duct member 30 according to any of the embodiments of the present invention. The duct member 30 functions to deliver cool air produced by the refrigerator. For example, some refrigerators have a cooling chamber in which an evaporator is provided for producing cool air. The air duct member 30 may be used to deliver cool air in the cooling compartment into the storage compartment. Or the air duct member 30 is used to deliver cool air in one compartment to another compartment. Or the air duct 310 defined by the air duct member 30 is a section of the complete air duct of the refrigerator.
The air duct member 30 may be mounted inside the inner liner 12. Specifically, as shown in fig. 1, the air channel member 30 is mounted inside the rear wall of the inner container 12. Of course, in other embodiments, the air duct member 30 may be mounted to a lateral side wall, bottom wall, or top wall of the liner 12.
FIG. 3 is an enlarged view at A of FIG. 2; FIG. 4 is an enlarged view at B of FIG. 2; fig. 5 is a schematic view of the air channel member 30 in a developed state; FIG. 6 is an enlarged view at C of FIG. 5; FIG. 7 is an enlarged view at D of FIG. 5; FIG. 8 is an expanded schematic view of an air duct member 30 according to another embodiment of the present invention; fig. 9 is an exploded view of fig. 8.
The air duct member 30 according to the embodiment of the present invention will be described with reference to fig. 3 to 9.
As shown in fig. 2 and 5, the air duct component 30 of an embodiment of the present invention may generally include a first cover plate 100 and a second cover plate 200. One side of the second cover plate 200 is connected to one side of the first cover plate 100 by at least one connection portion 305. The connection portion 305 is configured to allow the second cover plate 200 and the first cover plate 100 to be turned to a fastened state in which the inner side surfaces 101, 201 of the two are opposite to each other, so that the space between the first cover plate 100 and the second cover plate 200 forms an air duct 310 for guiding cool air inside the refrigerator. In fig. 2, the first cover plate 100 and the second cover plate 200 are in a buckled state.
Specifically, before the duct member 30 is manufactured, the base material of the duct member 30 includes the first cover plate 100 and the second cover plate 200 connected by the connection portion 305, and the base material is substantially in the form of an expanded plate as a whole. For example, the first cover panel 100 and the second cover panel 200 may be brought into a substantially coplanar condition to facilitate packaging. When the duct member 30 is manufactured, the first cover plate 100 or the second cover plate 200 is folded/turned over along the connection portion 305, and the two are folded to the above-described fastened state and positioned so as to be kept in the fastened state. At this time, the connection portion 305 constitutes one side of the air channel member 30.
The air duct component 30 according to the embodiment of the present invention includes the first cover plate 100 and the second cover plate 200, and the first cover plate 100 and the second cover plate 200 are connected by the connection portion 305 so as to be turned to a fastening state in which the inner sides 101 and 201 of the two are opposite to each other, so that the air duct 310 is formed by the interval between the two. The invention utilizes the turnover folding process to manufacture the air duct component 30, reduces or avoids the use of fasteners such as screws, reduces splicing and mounting procedures, ensures simpler structure and lower cost, and improves the assembly efficiency. And the splicing gaps are fewer, and the sealing performance is better.
In some embodiments, the first cover plate 100, the second cover plate 200, and the connecting portion 305 may together form an integral piece formed by a plastic molding process, that is, the three are three portions of one integral piece. When the first cover plate 100 or the second cover plate 200 is folded, the connecting portion 305 is deformed by the flexibility of the material thereof, allowing the first cover plate 100 or the second cover plate 200 to turn over. The first cover plate 100, the second cover plate 200 and the connecting portion 305 are made of PP material as a whole. Alternatively, the connection portion 305 may be made of a material that is more flexible and more foldable than the first cover plate 100 and the second cover plate 200.
Further, as shown in fig. 5, each connecting portion 305 may be a strip-shaped structure connected between the first cover plate 100 and the second cover plate 200, and in the embodiment shown in fig. 5, the number of connecting portions 305 is two, denoted as ab-segment and cd-segment respectively. The thickness of each connection portion 305 is smaller than the thicknesses of the adjacent sections of the first and second cover plates 100 and 200 and the connection portion 305 so as to be folded. In other words, the connection portion 305 is a thinned section having a thickness smaller than that of the adjacent section.
In some embodiments, as shown in fig. 5, the first cover plate 100 may include a first base plate 110 and a first flange 120 bent and extended from a peripheral edge of the first base plate 110, and the second cover plate 200 includes a second base plate 210 and a second flange 220 bent and extended from a peripheral edge of the second base plate 210. When the first cover plate 100 and the second cover plate 200 are in the buckled state, the first flange 120 and the second flange 220 are in sealing contact. When the first flange 120 abuts against the second flange 220, the first flange 120 may be located inside the second flange 220. In other embodiments, the second flange 220 may also be located on the inside. In this way, the first flange 120 and the second flange 220 are used to enclose the space between the first substrate 110 and the second substrate 210.
Further, as shown in fig. 5 to 7, the edge of the first substrate 110 and/or the edge of the first flange 120 may have at least one first clip strip 190 extending along the length direction thereof and having a "U" shape in cross section. In the illustrated embodiment, the first clip strip 190 extends from an edge of the first substrate 110. The edge of the second substrate 210 and/or the edge of the second flange 220 has at least one second clip strip 290 extending along its length and having a "U" shaped cross-section. In the illustrated embodiment, the second locking strip 290 extends from an edge of the second flange 220.
When the first cover plate 100 and the second cover plate 200 are in the buckled state, the convex side of each first clamping strip 190 is inserted into the concave side of the corresponding second clamping strip 290 so as to realize the buckling. Since the first and second locking strips 190 and 290 are each "U" -shaped, they are sufficiently resilient. The outer width of the first clamping strip 190 may be slightly larger than the inner width of the second clamping strip 290, so that after the first clamping strip 190 is inserted into the concave side of the corresponding second clamping strip 290, the first clamping strip 190 is forced to be extruded and narrowed, and the second clamping strip 290 is spread and widened, so that the first clamping strip 190 and the second clamping strip generate elastic force, and tight clamping is realized under the action of the elastic force. The embodiment of the invention realizes the positioning of the first cover plate 100 and the second cover plate 200 by using the clamping mode, and the assembly is simple and quick.
Further, as shown in fig. 2 to 4, the air channel member 30 is configured to be mounted inside the inner container 12 of the refrigerator, i.e., on the side defining the storage compartment 128. The inner side surface of the inner container 12 is provided with a strip-shaped clamping groove 121 formed by inwards sinking, and the second clamping strip 290 is also used for being clamped into the strip-shaped clamping groove 121 so as to realize the clamping and fixing of the air duct component 30 and the inner container 12. In this way, the concave side of the second locking strip 290 is used for being locked with the first locking strip 190, and the convex side is used for being locked with the liner 12, so that the dual function is achieved, and the design is very ingenious.
Further, as shown in fig. 5, the bottom end of the first substrate 110 may be extended downward to form a damper substrate 130, and the edge of the damper substrate 130 is bent to extend out of the damper flange 140. The bottom end of the second substrate 210 extends downward to form a door substrate 230 (see fig. 9), and the edge of the door substrate 230 extends out of the door flange 240. When the first cover plate 100 and the second cover plate 200 are in the buckled state, the door cover substrate 230 and the air door substrate 130 are buckled together, the air door flange 140 and the door cover flange 240 are sealed and abutted, so that a diversion space with a downward opening is formed for installing the air door, and the bottom opening of the diversion space forms an inlet 301 for air intake. Cool air enters between the door base 230 and the damper base 130 through the inlet 301, and then enters the air duct 310. The air door is used for controlling the on-off and the flow of the cold air.
The damper flange 140 may be provided with a first snap-in strip 190 and the door flange 240 may also be provided with a second snap-in strip 290 to facilitate snap-in securing of the damper flange 140 to the door flange 240.
In some embodiments, the inner side 101 of the first cover plate 100 and/or the inner side 201 of the second cover plate 200 are formed with a plurality of ribs 113, 114, 115, and the plurality of ribs 113, 114, 115 together with the inner side 101 of the first cover plate 100 and the inner side 201 of the second cover plate 200 enclose a wind channel 310. As shown in fig. 5, the inner side 101 of the first cover plate 100 is formed with three ribs 113, 114, 115, which are ribs 113, 114 arranged in a lateral direction, and ribs 115 located above the ribs 113, 114 and extending in the lateral direction, respectively. The bottoms of ribs 113 and 114 define the main flow path of air duct 310, ribs 113 and 115 define one branch flow path of air duct 310, and ribs 114 and 115 define the other branch flow path of air duct 310. Thus, the air duct 310 is made to intake air from the bottom and to discharge air to both lateral sides. The air duct member 30 has an air outlet 303 and an air outlet 304 on both lateral sides thereof, respectively.
In other embodiments, as shown in fig. 8 and 9, a thermal insulating foam layer 500 may be provided between the first cover plate 100 and the second cover plate 200. The heat insulating foam layer 500 plays a role of heat insulation, so that the cool air in the air duct 310 maintains the existing temperature. The inner side 101 of the first cover plate 100 is formed with a plurality of ribs 113, 114, 115, and the plurality of ribs 113, 114, 115 together with the inner side 101 of the first cover plate 100 and the insulating foam layer 500 enclose the air duct 310. In addition, a thermal insulating foam layer 600 may also be provided between the door cover substrate 230 and the damper substrate 130. When mounted to the liner 12, the first cover plate 100 may be oriented toward the liner 12. Of course, the second cover 200 may be directed toward the liner 12.
In some embodiments, as shown in FIG. 8, insulating foam layer 500 may be formed with grooves 510 that match the shape of air chute 310. When the first cover plate 100 and the second cover plate 200 are in the fastened state, the air channel 310 is defined by the groove 510, the plurality of ribs 113, 114, 115 and the inner side 101 of the first cover plate 100.
Further, the insulating foam layer 500 may be formed with a plurality of guide ribs 511, and the guide ribs 511 are located in the grooves 510 for guiding the direction of the airflow in the air duct 310. The length direction of the guide rib 511 may be identical to the direction of the duct 310.
In some embodiments, insulating foam layer 500 may be made as a preform. When the duct member 30 is assembled, the heat insulating foam layer 500, which has been processed, is first embedded inside the second cover plate 200, and then the second cover plate 200 is fastened to the first cover plate 100.
