Detailed Description
A refrigerator-freezer generally has a cabinet and a door. The embodiment of the invention firstly provides a door body of a refrigerating and freezing device. Fig. 1 is a schematic structural view of a door body of a refrigerating and freezing apparatus according to an embodiment of the present invention, and fig. 2 is a schematic structural exploded view of the door body according to an embodiment of the present invention. Referring to fig. 1 to 2, a door body 1 of a refrigerating and freezing apparatus according to an embodiment of the present invention includes a front panel 10 for forming a front portion of the door body 1, a door liner 20 for forming a rear portion of the door body 1, a door frame 30 for forming an outer frame of the door body 1, and a display assembly 40 between the door liner 20 and the front panel 10. The front panel 10 may be a glass panel that is transparent as a whole, or may be a panel made of another material having a see-through window. The door frame 30 may specifically include an upper molding 31, a lower molding 32, a first side frame 33, and a second side frame 34.
It should be understood by those skilled in the art that the front, back, front and back directions referred to in the present invention refer to the front and back directions of the door body 1 when the refrigeration and freezing apparatus mounted with the door body 1 is in a normal state and the door body 1 is closed, and the front and back directions are the depth direction of the door body 1 and the thickness direction of the door body 1.
The display module 40 includes a rear cover 41 fixed to the door frame 30, a light guide plate 42 disposed on a front side of the rear cover 41 and attached to a rear surface of the front panel 10, and a touch film 43 disposed on a surface of the light guide plate 42. Specifically, the light guide plate 42 may be an acrylic light guide plate to improve its structural strength and enhance its decorative effect. The touch film 43 may be attached, adhered, or otherwise suitably disposed on the front or rear surface of the light guide plate 42.
Fig. 3 is a schematic configuration view of a display module according to an embodiment of the present invention, fig. 4 is a schematic cross-sectional view taken along a sectional line a-a in fig. 3, fig. 5 is a schematic enlarged view of a portion B in fig. 4, a section line is hidden in fig. 5 for easy observation, and fig. 4 and 5 show relative positions and states of a light guide plate and a rear cover after a display module 40 and a front panel 10 are assembled. An elastic member 44 for urging the light guide plate 42 to have a moving tendency of forward movement is provided between the light guide plate 42 and the rear cover 41. That is, the elastic member 44 serves to provide the light guide plate 42 with an elastic force toward the front so that it has a moving tendency to move forward. Specifically, the elastic force provided by the elastic member 44 may urge the light guide plate 42 and the rear cover 41 away from each other, but since the rear cover 41 is fixed to the door frame 30, only the light guide plate 42 has a tendency to move forward.
The light guide plate 42 is connected to the rear cover 41 by a floating connector, which is fastened to the rear cover 41 and configured to allow the light guide plate 42 to have a space margin for moving forward after the display assembly 40 and the front panel 10 are assembled. That is, after the display assembly 40 and the front panel 10 are assembled, the floating connectors are fastened to the rear cover 41 and relatively immovable, but the floating connectors are relatively movable with respect to the light guide plate 42, and a space allowance is provided between the floating connectors and the light guide plate 42 to allow the light guide plate 42 to move forward. In other words, after the display assembly 40 and the front panel 10 are assembled, the floating connection member does not completely limit the front side of the light guide plate 42, and when the backward acting force applied to the light guide plate 42 disappears or is changed, the light guide plate 42 can still move forward within the above-mentioned space margin under the elastic force of the elastic member 44.
Therefore, when the front panel 10 of the door 1 is deformed due to foaming pressure or other reasons, the light guide plate 42 has a space margin for moving forward, so that the light guide plate 20 can automatically move forward under the elastic action of the elastic member 44, thereby maintaining a state of being in close contact with the front panel 10 and avoiding a gap between the light guide plate 42 and the front panel 10. Therefore, the invention can ensure the tight fit between the light guide plate 42 and the front panel 10 when the door body 20 is deformed, and overcomes the problem of inflexible touch caused by the deformation of the door body 20 due to foaming pressure or other reasons.
Fig. 6 is an exploded schematic cross-sectional view of a display assembly according to one embodiment of the invention. In some embodiments of the present invention, the floating connection member is a floating screw 45, and the floating screw 45 includes a limit cap 451, a polish rod portion 452, and a connection portion 453 that are sequentially connected from front to back. The connection part 451 passes through the light guide plate 42 from front to rear and is fixedly connected with the rear cover 41. The light rod portion 452 is slidably disposed through the light guide plate 42. The position limiting cap 453 is exposed at a front side of the light guide plate 42 to limit the forward movement of the light guide plate 42, and a space margin allowing the forward movement of the light guide plate 42 is formed between the position limiting cap 453 and the light guide plate 42 after the display assembly 40 and the front panel 10 are assembled. That is, after the display module 40 and the front panel 10 are assembled, a certain gap is formed between the stopper cap 453 and the light guide plate 42, and the gap forms the above-mentioned space margin. The stopper cap 453 does not have a stopper function on the light guide plate 42 at this time, and the light guide plate 42 is held by the abutment between the forward surface thereof and the front panel 10 and the abutment between the rearward surface thereof and the rear cover 41.
Fig. 7 is another sectional view of the display assembly according to one embodiment of the present invention, and fig. 7 illustrates relative positions and states of the light guide plate and the rear cover before the display assembly 40 and the front panel 10 are assembled. Further, the floating screw 45 is configured to make the light guide plate 42 abut forward against the stopper cap 453 by the elastic force of the elastic member 44 before the display assembly 40 and the front panel 10 are assembled, and make the forward surface of the light guide plate 42 more forward than the front end portion of the rear cover 41. Referring to fig. 7, a dotted line m is flush with the front surface of the light guide plate 42, and a dotted line n is flush with the front end of the rear cover 41. The dashed line m is located in front of the dashed line n. Specifically, the display module 40 does not interact with the front panel 10 and is independent of the front panel 10 before the display module 40 and the front panel 10 are assembled. At this time, the elastic force of the elastic member 44 acting on the light guide plate 42 away from the rear cover 41 (i.e., forward elastic utilization) urges the light guide plate 42 to abut against the stopper cap 453 positioned on the front side of the light guide plate 42. Also, the forward surface of the light guide plate 42 may be protruded forward from the front end portion of the rear cover 41 by the length design of the connection portion 453 of the floating screw 45 and the polish rod portion 452 and the specific connection structure of the connection portion 453 and the rear cover 41.
During the assembly of the display assembly 40 and the front panel 10, the light guide plate 42 is pressed by the front panel 10 since it protrudes forward. Under the pressing action of the front panel 10, the light guide plate 42 is separated from the stopper cap 453 backward, and the elastic member 44 is further compressed until both the front end portion of the rear cover 41 and the light guide plate 42 are engaged with the backward surface of the front panel 10, thereby forming a space margin between the light guide plate 42 and the stopper cap 453 to allow the light guide plate 42 to move forward.
Therefore, the suspension connecting piece is selected as the suspension screw 45 with special design, the connecting structure between the light guide plate 42 and the rear cover 41 is simplified, and the cost is reduced. In addition, the present invention achieves the unexpected effect of forming the above-mentioned space margin between the stopper cap 451 of the suspension screw 45 and the light guide plate 42 after the door body 20 is assembled, with a simple, inventive, and ingenious structural design by the cooperation of the suspension screw 45 and the elastic member 44.
It will be appreciated by those skilled in the art that in some alternative embodiments of the present invention, the floating connection member may also be another independent member or an assembly of several independent members capable of cooperatively promoting the light guide plate to have the above-mentioned space allowance in cooperation with the elastic member.
Fig. 8 is a partial structural view of a door body according to an embodiment of the present invention, in which a door liner, a foam layer, and an upper molding of a door frame are hidden in fig. 8 for easy observation. In some embodiments of the present invention, the rear cover 41 may include a main body portion 411 and a rim portion 412. The main body 411 defines therein a receiving chamber having a front-side opening. The rim portion 412 extends outward from at least a part of the edge of the front opening in a direction parallel to the front panel 10. The forward surface of the light guide plate 42 is more forward than the edge portion 412 before the display assembly 40 and the front panel 10 are assembled, and the edge portion 412 is attached to the rear surface of the front panel 10 after the display assembly 40 and the front panel 10 are assembled. That is, the rim portion 412 forms at least a part of the front end portion of the rear cover 41.
In some embodiments of the present invention, the display element 40 is disposed at a corner where the upper molding 31 and the first side frame 33 abut. The edge part 412 is disposed at the lower edge of the main body 411 and the inner edge far from the first side frame 33, the outer side wall of the main body 411 adjacent to the first side frame 33 is attached to the first side frame 33, and the upper end of the rear cover 41 is connected to the upper molding 31, so as to isolate the light guide plate 42 from a foam layer (not shown) filled between the rear cover 41, the door frame 30, the door liner 20 and the front panel 10. Therefore, the influence of the foaming pressure generated in the foaming process on the light guide plate 42 can be avoided, and the light guide plate 42 is prevented from being deformed or even damaged.
Specifically, the rear cover 41 and the upper molding 31, and the rear cover 41 and the first side frame 33 can be fastened and connected by screws. Screw holes in the rear cover 41 may be opened in the rim portion 412. The inboard middle part of first side frame 33 still can be equipped with limiting plate 331, and limiting plate 331 extends and is on a parallel with front panel 10 along vertical direction, and the certain distance of trim 31 is gone up apart from to the upper end of limiting plate 331, and the buckle 413 card of back lid 41 rear side is established in the upper end of limiting plate 331, and the postnotum of main part 411 is towards back butt in limiting plate 331 to carry out preliminary positioning to display element 40.
Further, the outer side surface of the light guide plate 41 adjacent to the first side frame 33 is exposed and is flush with the lateral surface of the first side frame 33, thereby ensuring that the door body 1 has a special visual effect and an elegant appearance effect.
In some embodiments of the present invention, the light guide plate 42 has a first connection hole 421 to be matched with the floating screw 45, a hole wall of the first connection hole 421 is smooth, and the polish rod portion 452 of the floating screw 45 is slidably inserted into the first connection hole 421 in the front-rear direction.
The rear cover 41 has a second coupling hole 414 coupled with the floating screw 45, and the second coupling hole 414 is screw-coupled with the coupling portion 453 of the floating screw 45. The connection portion 453 has an external thread, and the maximum outer diameter of the connection portion 453 is smaller than the diameter of the first connection hole 421 so that the connection portion 453 is smoothly connected to the second connection hole 414 through the first connection hole 421.
In some embodiments of the present invention, the rear side of the light guide plate 42 is formed with a concave groove 422 depressed forward, and the first connection hole 421 is located at the front side of the concave groove 422 and communicates with the concave groove 422. A boss 415 is formed at a position of the rear cover 41 corresponding to the concave groove 422, the boss 415 is inserted into the concave groove 422, and a second connection hole 414 is formed in the boss 415 and corresponds to the first connection hole 421, so that the floating screw 45 is simultaneously engaged with the first connection hole 421 and the second connection hole 414.
The concave-convex fit relationship between the light guide plate 42 and the rear cover 41 can reduce the thickness of the display module 40 in the front-rear direction, thereby increasing the thickness of the foaming layer in the region opposite to the front and rear of the display module 40 and ensuring that the door body 1 has a good heat preservation and insulation function.
