Description

Door for refrigerator and refrigerator

[ technical field ]

The present invention relates to a door for a refrigerator and a refrigerator, and more particularly, to a refrigerator door having a handle groove and a household refrigerator having the same.

[ background art ]

JP4050120B discloses a refrigerator, the door of which is provided with a handle groove and a grip portion facing the handle groove. The front side of the gripper part is covered by a detachable front panel, the front panel is provided with a flanging which is bent backwards, and the flanging is connected to the tail end of the gripper part and covers at least one part of the end part of the gripper part. When the user opens the door, some fingers extend into the handle slot to grab the grab portion to force the door open, and some fingers (such as a thumb) may press on the front panel during the process, which causes the flange to have a tendency to warp outward. If the front panel deforms so that the end face of the flange protrudes from the grip portion to form a step, the end face of the flange is easily touched by the fingers of a user during the door opening process. After a long time, the flanging may be deformed, even the connection between the opposite handles is loosened, and even an extreme situation in which the front panel falls off from the door may occur.

[ summary of the invention ]

It is an object of the present invention to overcome at least one of the technical problems of the prior art and to provide an improved door for a refrigerator and a refrigerator.

The above object is achieved by the features of the independent claims. Preferred embodiments of the invention are the subject of the figures, the description and the dependent claims.

An aspect of the present invention relates to a door for a refrigerator. A door for a refrigerator, the door comprising a front panel, a handle groove behind the front panel and a grip facing the handle groove, the front panel covering the grip and comprising a flange bent back from one end thereof, the flange being connected to the grip, characterized in that the flange and/or the grip has at least one positioning protrusion, the grip and/or the flange has at least one positioning groove, the positioning protrusion and the corresponding positioning groove being inserted in the front-rear direction of the door.

Because the fixing structure inserted in the front-back direction is arranged between the flanging and the hand grip part, the inserting connection of the positioning protrusion and the positioning groove is facilitated, and the positioning protrusion positioned in the positioning groove can reduce the outward warping trend of the flanging, so that even if a user can frequently apply force and touch the front panel when the door is opened, the deformation of the flanging can be effectively restrained. This is also particularly advantageous for maintaining a constant gap between the cuff and the grip.

On the other hand, the positioning projection inserted into the positioning groove in the front-rear direction can prevent the burring from moving relative to the grip portion in the depth direction of the handle groove, which facilitates the front panel to be stably held on the door. This is particularly advantageous when the front panel is part of a user electrical interface, to ensure the reliability of the user interface.

In one possible embodiment, the flange and the gripper portion may each form a positioning protrusion and a positioning groove, the positioning protrusion of the gripper portion being inserted into the positioning groove of the flange, and the positioning protrusion of the flange being in plug-in connection with the positioning groove of the gripper portion. In another possible embodiment, it is also possible that one of the turned-up edge and the hand grip has a positioning projection and the other of the turned-up edge and the hand grip has a positioning slot.

In one possible embodiment, a locating projection extends along at least a majority of the length of the grip or cuff. In an alternative embodiment, a plurality of spaced locating tabs are inserted into corresponding locating slots.

In one embodiment, the handle slot may be open toward a side of the door, such as a longitudinal side or a lateral side of the door. In an alternative embodiment, the entrance to the handle slot may also face away from the side of the door closer to the handle slot.

When the door is mounted on the refrigerator, the front panel is exposed to the front side of the door. In addition to the handle slots and the hand grips, the rear side of the front panel may be provided with an appliance module, for example the rear side of the front panel may be provided with an input/output appliance module, whereby the front panel forms part of the user interface. It is then also possible in an alternative embodiment for the user interface to be arranged separately from the front panel, for example on the cabinet or on another part of the door separate from the front panel.

In one embodiment, the handle slot may extend longitudinally on the door (e.g., disposed near the left or right side of the door), where the depth direction of the handle slot is referred to as the lateral direction of the door. In another embodiment, the handle slot may extend horizontally on the door (e.g., disposed near an upper or lower side of the door), where the depth direction of the handle slot is the longitudinal direction of the door.

Other features which are considered as characteristic for the invention, individually or in combination with other features, are set forth in the following appended claims.

In one possible embodiment, the at least one positioning protrusion may be formed by a tab.

In one possible embodiment, the positioning groove and the positioning protrusion may not be exposed to the outer surface of the flange. So that the arrangement of the positioning grooves and the positioning protrusions does not have to affect the appearance of the door.

In one possible embodiment, at least one of the positioning slots may be located at least partially between the inner and outer surfaces of the flange. The positioning groove is at least partially positioned in the flanging, so that the flanging is particularly favorable for preventing deformation.

In one possible embodiment, the positioning protrusions may include a first positioning protrusion provided to the grip portion and a second positioning protrusion provided to the flange, and the positioning groove includes a first positioning groove provided to the flange and a second positioning groove provided to the grip portion, the first positioning protrusion being inserted into the first positioning groove, and the second positioning protrusion being inserted into the second positioning groove. Because the handle part and the flanging are respectively provided with the positioning protrusions and the positioning grooves, the connection stability between the handle part and the flanging is increased, and the insertion structure is favorable for generating a multi-dimensional position stopping effect on the flanging.

In one possible embodiment, the second positioning projection and the first positioning projection may at least partially overlap and contact in a depth direction of the handle groove.

In one possible embodiment, the second detent projection may define at least part of the boundary of the first detent and/or the first detent projection defines at least part of the boundary of the second detent. For example, a second positioning protrusion is arranged in a first positioning slot on one of the handle portion and the flange, a hollow first positioning protrusion is arranged on the other one of the handle portion and the flange, the first positioning protrusion is inserted into the first positioning slot, and the second positioning protrusion is inserted into a second positioning slot surrounded by the first positioning protrusion, so that the first positioning protrusion forms the whole boundary of the second positioning slot.

In one possible embodiment, the second positioning protrusion may be connected to an inner surface of the flange and protrude inward. Therefore, the second positioning protrusion does not need to protrude out of the flange, and the appearance of the outer side of the flange does not need to be influenced.

In one possible embodiment, the locating projection and the locating slot may together define movement of the cuff in at least two dimensions.

In a possible embodiment, a plurality of buckling structures can be further arranged between the flanging and the handle part, and the buckling structures and the positioning protrusions and the positioning grooves which are connected in an inserted mode are alternately arranged in the length direction of the handle part. Thus, the cuff and the hand grip can be more stably fixed together.

In one possible embodiment, the free end of the grip portion may have a connecting wall facing the inner surface of the flange, and the positioning projection and the positioning groove are located between the connecting wall and the outer surface of the flange.

In one possible embodiment, the positioning protrusion may include a first positioning protrusion in a tongue shape on the grip portion with a space therebetween.

In one possible embodiment, the positioning groove may include a second positioning groove on the hand grip and a second positioning protrusion on the flange, the connecting wall being inwardly recessed at a position corresponding to the first positioning protrusion to form the second positioning groove between the connecting wall and the first positioning protrusion, the second positioning protrusion being located inside the flange and inserted into the second positioning groove.

In one possible embodiment, the free end of the grip portion has an outwardly protruding step, the distal end surface of the burring faces the step and the burring does not protrude beyond the step in the depth direction of the handle groove. Therefore, the tail end of the flanging can be shielded by the step part protruding from the hand grip part, and when a user grasps the hand grip part to open the door, the tail end surface of the flanging is not touched, so that the possibility of outward tilting of the flanging is further reduced.

In one possible embodiment, the door may further include an appliance module covered by the front panel, and the handle slot and the appliance module are disposed side by side in a depth direction of the handle slot. Thus, the handle groove and the electric module may not be overlapped in the length direction of the handle groove, which is particularly advantageous for increasing the length of the handle groove.

The invention relates to a door for a refrigerator, which is characterized by comprising a front panel, an electrical appliance module and a handle groove, wherein the electrical appliance module and the handle groove are positioned behind the front panel, the handle groove and the electrical appliance module are arranged side by side in the depth direction of the handle groove, the front panel covers the electrical appliance module and a handle part positioned in front of the handle groove, one side of the front panel is provided with a flanging bent backwards, the flanging is connected with the free end of the handle part, and a fixing structure is arranged between the flanging and the handle part; the fixing structure comprises a buckling structure and/or an inserting structure, the buckling structure is used for buckling and connecting the handle part and the flanging, the inserting structure comprises at least one positioning protrusion arranged on the handle part and/or the flanging and at least one positioning groove arranged on the flanging and/or the handle part, and the positioning protrusion is inserted into the corresponding positioning groove in the front-back direction of the door.

In one embodiment, the appliance module may be a user interface appliance module. The appliance module may include an input unit for receiving a user input instruction and/or an output unit for displaying information to a user. For example, the electrical module may include a touch unit to receive a touch instruction of a user. In an alternative embodiment, the user interface electrical module may also receive the user's command through other input devices such as keys.

Yet another aspect of the invention relates to a refrigerator comprising a door as claimed in any one of the above.

Fig. 1 illustrates a schematic perspective view of a refrigerator 100 according to a preferred embodiment of the present invention. As shown in fig. 1, the refrigerator 100 includes a main body 5 having a first storage chamber (not shown) and a second storage chamber (not shown) disposed side by side. The refrigerator 100 further includes a pair of half doors 1, 1' connected to the main body 5 to close the respective storage compartments, respectively.

The door 1 has an insulating layer 17 (fig. 5) between the door panel 11 and the inner lining 16. Referring to fig. 2 in conjunction with fig. 1, the door 1 has an integrated operation center 6. The operation center 6 includes a user interface 61 and a handle slot 132 integrated into the operation center 6. When the door 1 is opened or closed, a user's hand may extend into the handle groove 132.

The operation center 6 further includes a recess 133, and the user's hand enters the handle groove 132 through the recess 133. The recess 133 is opened to the front surface 101 and the side surface 102 of the door 1 to be exposed to the front and right sides of the door 1, and thus is accessible from the front and right sides of the door 1.

The operation center 6 is provided on the side of the door 1 opposite to the other door 1'. In this embodiment, the door 1' also has a recess and a handle slot (not shown) accessible from the recess. The depressions of a pair of doors 1, 1' are oppositely disposed and may have the same length.

The user interface 61 is arranged to accept input from a user and/or to output information to a user. The user interface 61 includes a front panel 14 and an appliance module 15 located behind the front panel 14.

The appliance module 15 may include an output unit to output information (e.g., setting information about the refrigerator 100 and/or food stored in the refrigerator 100, or information unrelated to the refrigerator such as video/photos) to a user and/or an input unit to receive a user's instruction.

The front panel 14 may include a plurality of touch areas 14a and/or display areas 14b indicated by touch indicia. The electrical module 14 may include a touch unit to receive an instruction input by a user through operating the touch area 14a and/or the display area 14 b.

In the present embodiment, the front panel 14 is attached to the door 1 after the foaming process of the door 1 is completed, that is, the front panel 1 does not contact the heat insulating layer 17 of the door 1. By suitable means, the front panel 14 can be detached from the door 1 without damaging the insulation layer 17 of the door 1, and without damaging the door 1.

The door 1 includes a receiving space 131 depressed rearward to receive the electrical module 15. The receiving space 131, the handle groove 132 and the recess 133 may be located in the same interface housing 13. The interface housing 13 is connected to the door panel 11, and its rear side is closely connected to the insulation layer 17. The gripping portion 135 may be integrally formed on the interface housing 13. The grip portion 13 may have embedded therein a reinforcing insert 1353.

The electrical module 15 and the handle groove 132 and the recess 133 are arranged side by side in the depth direction D of the handle groove, so that the user interface 61, the handle groove 132 and the recess 133 can be integrated in a compact area, while the handle groove 132 can have a sufficiently large length.

Also covered by the front panel 14, together with fig. 2-5, is a grip portion 135 located forward of the handle slot 132. When a user's hand is inserted into the handle groove 132, fingers positioned in the handle groove 132 may be pulled on the grip portion 135.

The front panel 14 includes a front plate portion 141 covering the accommodation space 131 and a flange 142 bent rearward from a first side of the front plate portion 141. The first side of the front plate portion 141 is adjacent to the entrance of the handle groove 132.

The front plate portion 141 covers the electric module 15 and the hand grip 135 in the front-rear direction of the door 1. The flange 142 is connected to the grip portion 135 and covers at least a part of the grip portion 135 in the depth direction D of the handle groove (in the present embodiment, the width direction/lateral direction of the door 1). With this, the end surface of the front panel 14 is not easily exposed to the user, which is advantageous in that a portion where the door 1 is easily seen by the user has a neat appearance.

In the present embodiment, the electrical module 15 may be fixed to the rear side of the front plate portion 141. The rear side of the front plate 141 has a fixing portion 1411 for fixing the electrical module 15. The fixing portion 1411 includes a plurality of hooks 1412, and the hooks 1412 are fastened to the electrical module 15.

The front plate portion 141 includes a plurality of hook-shaped latching portions 137 for engaging with the interface housing 13. The catching portion 137 extends rearward from the rear surface of the front plate portion 141 and forms a hook portion at the tip. The locking portion 137 is connected to the second side of the front plate portion 141 on which the flange is not provided and extends rearward.

The locking portion 137 is locked in a recess (not shown) of the interface housing 131, and the recess is located in a wall defining the accommodating space 131.

Since the user may press the front plate portion 141 located right in front of the handle groove 131 when opening the door, the front plate 14 may be deformed, for example, the flange 142 may be warped outward, an uneven gap may be formed between the flange 142 and the grip 135, and the front plate may be easily detached from the door 1.

According to the embodiment of the present invention, a fixing structure for preventing the burring 142 from being deformed in the depth direction D of the handle groove and even from being separated from the grip portion 135 is provided between the burring 142 and the grip portion 135.

The fixing structure includes a plurality of snap structures 3 for snap-connecting the grip portion 135 and the flange 142, and a plurality of insertion structures 4 for inserting and connecting the grip portion 135 and the flange 142. The latching structures 3 and the plug-in structures 4 are distributed alternately and with a spacing in the longitudinal direction of the hand grip 135.

The snap structure 3 includes a plurality of hooks 31 provided on the turned-up edge 142 and/or the hand grip 135 and a plurality of recesses 32 provided on the hand grip 135 and/or the turned-up edge 142 to be engaged with the corresponding hooks 31.

The insertion structure 4 includes at least one positioning protrusion 41, 42 provided on the hand grip 135 and/or the flange 142 and at least one positioning groove 43, 44 provided on the flange 142 and/or the hand grip 135, the positioning protrusion 41, 42 being inserted into the corresponding positioning groove 43, 44 in the front-rear direction of the door 1.

In the embodiment shown in fig. 3-6, hand grip 135 has a plurality of tabs spaced apart along the length of hand grip 135. These tabs form respective first positioning projections 41.

As shown in fig. 3, the free end of the gripper portion 135 has a connecting wall 1351 protruding forward. The inner surface 1420 of the cuff 142 and the connecting wall 1351 are disposed in face-to-face relation.

The first positioning protrusion 41 has a spacing from the connection wall 1351 in the depth direction D of the handle groove. The connecting wall 1351 has a plurality of depressions inwardly depressed at a position corresponding to each of the first positioning protrusions 41, thereby forming second positioning grooves 44 between the first positioning protrusions 41 and the respective depressions.

As shown in fig. 4, the inner side of the flange 142 has a plurality of first positioning grooves 43 spaced apart to receive the first positioning protrusions 41. The first detent 43 is located partially between the inner surface 1420 and the outer surface 1421 of the flange 142. A part of the boundary wall of the first positioning groove 43 is connected to the inner surface 1420 of the flange 142 and protrudes from the inner surface 1420 of the flange 142 and forms the second positioning projection 42.

The first positioning protrusion 41, the second positioning protrusion 42, the first positioning groove 43, and the second positioning groove 44 are located between the connecting wall 1351 and the outer surface 1421 of the burring 142, and are not exposed to the outer surface 1421 of the burring 142.

As shown in fig. 5, the first positioning projection 41 and the second positioning projection 42 are at least substantially perpendicular to the front plate portion 141, and the first positioning groove 43 and the second positioning groove 44 have an entrance opening backward and an entrance opening forward, respectively, so that the first positioning projection 41 and the second positioning projection 42 can be inserted into the first positioning groove 43 and the second positioning groove 44, respectively, in the front-rear direction.

Since the second positioning projection 42 defines a partial boundary of the first positioning groove 43 and the first positioning projection 41 defines a partial boundary of the second positioning groove 44, the first positioning projection 41 and the second positioning projection 42 overlap and contact in the depth direction D of the handle groove, so that the second positioning projection 42 forms a stopper wall of the first positioning projection 41.

Both ends of the second positioning projection 42 have a shape adapted to the second positioning groove 44. When the second positioning projection 42 is inserted into the second positioning groove 44, both ends of the second positioning projection 42 are stopped by the second positioning groove 44, thereby preventing the burring 142 from moving in the length direction of the handle groove 132. Thus, in this embodiment, the plug structure 4 can prevent movement of the flange 142 relative to the grip 135 in two dimensions.

In the present embodiment, since the first positioning groove 42 is substantially shaped like a waist, and both ends of the second positioning protrusion 42 are arc-shaped, both ends of the second positioning groove 44 are also arc-shaped.

As shown in fig. 6, the hooks 31 are received in the corresponding recesses 32 to be hooked with the hook portions at the edges of the recesses 32, thereby preventing the flanges 142 from moving in the front-rear direction relative to the grip portion 135.

The free end of the grip portion 135 has a step portion 1352 protruding outward from the connecting wall 1351, and the tip end surface of the burring 142 faces the step portion 1352 and does not protrude from the step portion 1352 in the depth direction D of the handle groove, so that the user's hand does not scrape on the tip end surface of the burring 142 when opening the door.

In summary, the movement of the turned edge 142 relative to the grip 135 in the depth direction D of the handle groove is stopped by the first positioning portion 41 inserted into the first positioning groove 43 and the second positioning portion 42 inserted into the second positioning groove 44, the movement of the turned edge 142 relative to the grip 135 in the length direction of the handle groove 132 is stopped by the second positioning portion 42 inserted into the second positioning groove 44, and the movement of the turned edge 142 relative to the grip 135 in the front-rear direction is stopped by the latch structure 3, so that the movement of the turned edge 142 and the grip 135 in three dimensions is restricted, which effectively prevents the deformation of the turned edge 142.

In addition, as the buckling structures 3 and the inserting structures 4 are alternately arranged at intervals in the length direction of the handle groove 132, the reliability of the fixing structure is increased, and the flanging 142 is further prevented from being deformed and outwards warped.

To further prevent the front panel 14 from falling off the door 1, in a preferred embodiment, the door 1 further includes a screw-fastening structure for screw-fastening the front panel 14 to the interface housing 13. The screw-fixing structure is located between the first and second sides of the front plate portion 141 in the lateral direction of the door 1.

The screw-fastening structure includes a leg portion 5 extending rearward from the rear side of the front plate portion 141, the leg portion 5 having a first hole 51 penetrating the leg portion 5. The leg portion 5 is located between the first side and the second side of the front plate portion 141. The first hole 51 is perpendicular to the depth direction D of the handle groove.

Accordingly, the interface housing 13 has a fixed wall 6, the fixed wall 6 having a second hole 61. When the front panel 14 is mounted on the door 1, the leg portion 5 and the fixing wall 6 overlap in the depth direction D of the handle groove, and the first hole 51 and the second hole 61 are concentric. The leg portion 5 and the fixing wall 6 are located between a partition wall 134 partitioning the accommodation space 131 of the handle groove 132 and a boundary wall 136 of the accommodation space 131 opposite to the partition wall 134.

Further, the partition wall 134 partitioning the handle groove 132 and the accommodating space 131 is provided with a third hole 1341 concentric with the first and second holes 51 and 61. A screw fastener (e.g., a screw, not shown) passes through the third hole 1341, the first hole 51, and the second hole 61 in this order to fix the front panel 14 to the door 1. The threaded fastener may be threadedly coupled to the second bore 61.

The various embodiments of the individual components described in connection with fig. 1 to 6 may be combined with each other in any given way to achieve the advantages of the invention. In addition, the present invention is not limited to the illustrated embodiments, and other means than those shown may be generally used as long as the same effects are obtained.
