Detailed Description

In order that the above-recited objects, features and advantages of the present utility model will become more readily apparent, a more particular description of the utility model briefly described above will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.

Fig. 1 is a schematic diagram of a refrigeration appliance 100 according to an embodiment of the present utility model.

In some embodiments, the refrigeration appliance 100 may be, for example, a refrigerator, a freezer, a wine cabinet, or the like.

For convenience of description, in the present embodiment, the width direction of the refrigerator 100 is referred to as the x-direction, the depth direction is referred to as the y-direction, and the height direction is referred to as the z-direction. In the present embodiment, the front-rear direction refers to the y direction and the reverse direction thereof, wherein the front or front side refers to the direction facing the user when the refrigerator 100 is in use, and the rear or rear side refers to the direction facing away from the user when the refrigerator 100 is in use.

Specifically, referring to fig. 1, the refrigeration appliance 100 according to the present embodiment may include a case 101 defining at least one compartment (not shown, and may also be referred to as a storage compartment). The storage chamber may include a freezing chamber, a refrigerating chamber, a temperature changing chamber, or the like.

Further, the refrigerator 100 may further include a door 1, the door 1 being movably coupled to the front of the cabinet 101 to open or close at least a portion of the storage compartment.

In some embodiments, the door 1 may be hinged to the case 101 and may pivot with respect to the case 101 to open or close at least a portion of the storage compartment.

In some embodiments, the door 1 may integrally move in a direction away from or near the cabinet 101 to open or close at least a portion of the storage compartment. In particular, the door 1 may comprise a drawer type door.

For example, a side of the drawer door facing the storage compartment is connected to a support structure (not shown), which is also connected to a side wall of the storage compartment. Thus, the drawer type door may be moved in the y direction or the opposite direction thereof under the supporting and guiding actions of the supporting mechanism to open or close the storage compartment. Further, the stored items may be placed directly in the storage compartment.

For another example, a drawer door may be coupled to a drawer (not shown), the storage compartment adapted to receive the drawer, and the support structure adapted to couple a side wall of the drawer to a side wall of the storage compartment. Thus, by pulling or pushing the drawer door under the supporting and guiding action of the supporting mechanism, the drawer door and the drawer can be moved together in the y direction or the opposite direction to open or close at least a portion of the storage compartment. Wherein, when the storage chamber is opened, the drawer moves along with the drawer type door in the y direction and is exposed to the external environment; when the storage room is closed, the drawer moves along with the drawer type door in the reverse direction of the y direction and is isolated from the external environment, so that the sealing effect is achieved. Further, the storage may be placed in a drawer.

Next, a specific structure of the door 1 according to the present embodiment will be described in detail with reference to fig. 2 to 18 by taking a drawer type door as an example.

In one implementation, the door 1 may include a door body 11 with reference to fig. 1-3. Specifically, the door body 11 may include a front panel 111, a rear cover (not shown), and a door frame 112 closing the side of the door body 11, the front panel 111, the rear cover, and the door frame 112 defining a heat insulation space filled with a heat insulation material to form a heat insulation layer. When the door 1 closes at least a portion of the storage compartment, the heat insulating layer formed in the heat insulating space plays a role of insulating heat to ensure superior refrigerating/freezing effect of the storage compartment. The rear cover faces the case 101 when the door 1 closes the storage compartment. The door frame 112 may also be referred to as a rim, and is disposed along the periphery of the door body 11. In some embodiments, the front panel 111 forms at least a portion of a front boundary of the insulating space such that the insulating material contacts a rear side of the front panel 111. In other embodiments, another door panel may be provided on the rear side of the front panel 111. The front panel 111 may be a glass plate or a ceramic plate.

Further, the door body 11 has a groove 113 that opens toward one side surface and the front surface 1a of the door body 11. Wherein the front surface 1a (which may also be referred to as the surface of the door) may comprise the face of the front panel 111 facing away from the cabinet 101 (i.e. the face of the refrigerator 100 facing towards the user in use), i.e. the recess 113 is at least open towards the front. Further, the recess 113 may be upwardly opened as shown in fig. 3 to 6 (in fig. 6, for more clearly showing the specific structure of the door 1, a plurality of parts obtained by explosion are exemplarily shown in different views, the third connection member 271 is not shown in fig. 6), that is, the front panel 111 of the door body 11 and at least a portion of the door frame 112 closing the upper side of the door body 11 are notched to form the recess 113 at the front upper end of the door body 11. In practical applications, the specific arrangement position of the groove 113 on the door body 11 may be adjusted as required, for example, the groove 113 may be opened forward and toward the left/right/lower side of the door body 11, thereby forming the groove 113 at the left/right/front lower end of the door body 11.

Further, the door 1 may further include a handle assembly 2 mounted to the recess 113, and the handle assembly 2 may be adapted to form a door handle for a user to grasp. In some embodiments, the arrangement position of the groove 113 on the door body 11 may be adjusted according to the arrangement position of the door 1 on the case 101, so that the position of the handle assembly 2 on the door 1 is convenient for a user to operate. For example, when the door 1 is positioned at the middle of the case 101 in the z-direction as shown in fig. 1 and 2, the groove 113 may be formed at the upper end of the door body 11 and opened upward toward the front, so that the user can conveniently access the handle assembly 2 provided at the groove 113 in a standing posture without bending down or cushioning feet, thereby operating the door 1 in a more ergonomic posture. For another example, when the door 1 is positioned at the upper portion of the case 101 as shown in fig. 1 and 2, the groove 113 may be formed at the left/right side of the door body 11 so that the user can access the handle assembly 2 without bending down or cushioning the foot as well, thereby opening and closing the door 1 more effort.

In some embodiments, the grooves 113 may have different depths at different locations along the x-direction to accommodate different configurations of the handle assembly 2, ensuring that the upper end surface of the door 1 remains flat without protruding structures. Thus, the appearance of the door 1 is more compact and beautiful.

In some embodiments, along the x-direction, the groove 113 extends substantially to the end of the door body 11. Thus, the handle assembly 2 extends a distance in the direction of extension (e.g., parallel to the x-direction) that is long enough to be grasped by a user.

In one implementation, with continued reference to fig. 1-5, the handle assembly 2 may include a movable handle body 21, the handle body 21 having at least a first position and a second position.

Specifically, the handle body 21 in the first position may be flush with the front panel 111, as shown in fig. 1. Due to manufacturing tolerance problems, the front-rear difference in the y-direction between the front surface of the handle body 21 and the front surface 1a of the door 1 is within ±1 to 2mm (including 1 mm), both of which can be considered to be flush.

For example, the handle body 21 may form the front surface 1a of the door 1 together with the front panel 111 when in the first position. Thus, the handle body 21 in the first position is substantially hidden in the door body 11, and the front surface of the door 1 is more beautiful. Further, the surface of the door body has no protruding structure, and the refrigerator 100 in which the door 1 of the present embodiment is installed has higher safety during use.

Alternatively, the handle body 21 in the first position may protrude from the front panel 111. At this time, the handle body 21 may protrude from the front panel 111 in parallel to the front surface 1a of the door 1.

The handle body 21 in the first position may be regarded as being in a hidden state, the handle body 21 being hidden within the door 1, substantially only the front surface of the handle body 21 being exposed to the front surface 1a of the door 1.

Further, when the handle body 21 is located at the second position, it protrudes further from the front panel 111 than when it is located at the first position, as shown in fig. 2 to 5. At this time, the handle body 21 is formed as a grip portion for gripping, and an operation space 211 into which a hand is inserted is formed between the handle body 21 and the front panel 111. The handle body 21 in the second position may be regarded as being in an ejected state, the handle body 21 protruding forward from the front surface 1a of the door 1 to enlarge a gap between the handle body 21 and the door body 11 (e.g., the front panel 111), the enlarged gap being adapted to form an operation space 211 into which a sufficient hand is inserted.

In some embodiments, with continued reference to fig. 4 and 5, the operating space 211 may be open downward. The user's hand may be inserted into the operation space 211 from below to grasp the handle body 21, thereby operating the door 1 to move.

In some embodiments, the handle body 21 may include adjacent first and second panels 212, 213, the angle between which ranges from (0 °,180 °). For example, the angle between the first panel 212 and the second panel 213 may be 90 °, and accordingly, the handle body 21 may have an L-shape in a cross-section perpendicular to the x-direction, and the handle body 21 may be also referred to as an L-shaped handle.

Further, when the handle body 21 is in the first position, the first panel 212 is adapted to cover the upward opening of the recess 113, and the second panel 213 is adapted to cover the forward opening of the recess 113.

Further, the second panel 213 may extend to an end of the door body 11 in the x-direction.

Further, the handle body 21 may remain parallel to the front panel 111 at all times in the first position, the second position, and during the switching of the two positions so far.

Further, when the handle body 21 is in the first position, the second panel 213 protrudes from the front panel 111 flush with or parallel to the front surface 1a, and at this time, a gap between the second panel 213 and the front surface 1a is almost negligible or insufficient for the user's finger to extend. When the handle body 21 is located at the second position, the second panel 213 protrudes from the front surface 1a more than when it is located at the first position, and the gap between the second panel 213 and the front surface 1a is increased to form an operation space 211 into which a user's hand extends.

In some embodiments, the lower edge of the second panel 213 may be curved or, alternatively, sloped rearward and upward to further improve the grip feel.

In one implementation, the movement of the handle body 21 between the first and second positions may include linear movement. For example, fig. 1-5 illustrate an example in which the handle body 21 is movable in a first direction (e.g., the y-direction) and vice versa between a first position and a second position. Thereby, the handle body 21 can be ejected in a linear motion to switch from the hidden state to the ejected state for grasping by the user.

In a variation, the movement of the handle body 21 between the first and second positions may comprise a rotational movement. For example, the handle body 21 may be pivoted out of the door body 11 about a rotation axis parallel to the x-direction to provide a location for a user to operate the pull-out door 1. Thereby, the handle body 21 can be rotated to pop up to switch from the hidden state to the pop-up state for grasping by the user.

In one implementation, with continued reference to fig. 3-6, the door 1 may further include: the door rear end 12 is located right behind the groove 113, and the door rear end 12 has a heat insulating layer. That is, the handle assembly 2 and the case 101 are separated from each other by the door rear end portion 12 having the insulating layer in the entire width direction (e.g., parallel to the x direction) of the door 1, so that the insulating effect of the door 1 at the handle is also excellent.

Specifically, the front surface of the door rear end portion 12 is adapted to form the rear wall of the recess 113. In some embodiments, the door rear end 12 is flush with the handle assembly 2 at the side of the door body 11 (e.g., the upper side of the door body 11) where the recess 113 is open, whereby the overall appearance of the door 1 is more aesthetically pleasing. Alternatively, the upper edge of the handle body 21 may be slightly higher than the upper end of the door rear end portion 12, for example, the upper edge of the handle body 21 may protrude upward by 1 to 2mm as compared to the upper end of the door rear end portion 12 to shield the handle seat 22 and the door rear end portion 12 at the front surface of the door 1, beautifying the appearance of the refrigerator 100.

Further, a dimension W1 of the door rear end portion 12 in the thickness direction (e.g., y direction) of the door body 11 may be smaller than a dimension W2 of the recess 113 in the thickness direction of the door body. For example, the dimension of the door rear end 12 in the y-direction may be no less than 10mm to form a sufficiently thick insulating layer behind the handle assembly 2. For another example, the groove 113 may have a thickness of 25mm or more to improve stability when the handle body 21 moves and to enable the handle body 21 in the second position to form a larger operation space 211.

It should be noted that the door rear end 12 may not be a regular plane. At this time, the dimension W1 of the door rear end portion 12 in the y direction in the present embodiment may specifically refer to a distance between a face of the door rear end portion 12 for mounting a door seal (also referred to as a door seal, not shown) to a rear wall of the recess 113.

In some embodiments, the relationship between the dimension W1 of the door rear end 12 in the thickness direction of the door body 11 and the dimension W2 of the groove 113 in the thickness direction of the door body 11 may be: w1 is less than or equal to W2. That is, the specific value of the dimension W2 may be not less than 2 times W1. Therefore, the handle assembly 2 can run stably, the heat insulation performance of the door 1 at the handle assembly 2 can meet the requirement, and condensation is not easy to generate.

In some embodiments, with continued reference to fig. 3, the relationship among the distance D of the handle body 21 from the first position to the second position, the dimension W1 of the door rear end 12 in the thickness direction of the door body 11, and the dimension W2 of the groove 113 in the thickness direction of the door body 11 may be: w1 is more than or equal to D is more than or equal to W2. Thus, the distance that the handle body 21 in the second position protrudes from the front panel 111 is ensured to be large enough to form a large operation space 211, and the user's hand is not easily pinched into the operation space 211, and the operation in the operation space 211 is comfortable.

In some embodiments, the dimension W1 of the door rear end portion 12 in the thickness direction of the door body 11 may range from: w1 is more than or equal to 8mm and less than or equal to 15mm. Thereby, a sufficiently thick insulating layer is formed behind the handle assembly 2, enhancing the insulating effect in the vicinity of the handle.

In one embodiment, the dimension W2 of the groove 113 in the thickness direction of the door body 11 may range from: w2 is less than or equal to 30 mm. Thereby, a smoother movement of the handle body 21 between the first position and the second position is achieved.

In some embodiments, the distance D of the handle body 21 from the first position to the second position is greater than or equal to 25mm. Thus, a large operation space 211 is formed, and the user's hand is not easily pinched by the operation space 211, and the operation in the operation space 211 is comfortable.

In some embodiments, the overall thickness dimension of the door 1 in the y-direction may be around 60-80 mm.

In one implementation, with continued reference to fig. 3-6, the handle assembly 2 may include a handle base 22 with the handle body 21 movably coupled to the handle base 22. Specifically, the recess 113 is adapted to form the handle seat 22 for the movable connection of the handle body 21.

In some embodiments, with continued reference to fig. 1-6, the handle body 21 is adapted to shield a majority of the structure of the handle base 22 from the front and from above. Thus, the front surface of the refrigerator 100 is more beautiful, and even when the handle body 21 is moved to the second position to allow the user to pull the door 1 out by pulling the handle body 21, the exposed portion of the handle seat 22 is within an acceptable range (as shown in fig. 2) by reasonably controlling the value of the distance D, and the appearance of the door 1 in the opened state can be maintained to be beautiful.

In one implementation, with continued reference to fig. 3, 5 and 6, the handle assembly 2 may further include a drive mechanism 23 disposed on the handle base 22, the drive mechanism 23 being configured to drive movement of the handle body 21 in at least a first direction away from the front surface 1a of the door 1. Wherein the first direction is perpendicular to the front surface 1a of the door 1, i.e. parallel to the y-direction.

Specifically, the drive mechanism 23 may apply a force in the y-direction to the handle body 21 to drive the handle body 21 to eject straight from the first position shown in fig. 1 to the second position shown in fig. 2. For example, the force of the driving structure 23 may be applied to the second panel 213.

Further, the driving mechanism 23 may also drive the handle body 21 to move in a direction opposite to the first direction (e.g., opposite to the y direction) toward the front surface 1a of the door 1 to return the handle body 21 from the ejected state shown in fig. 2 to the hidden state shown in fig. 1.

In some embodiments, the drive mechanism 23 may be disposed in the middle of the handle body 21 in the extending direction (e.g., x-direction). Thereby, the handle body 21 can be moved in a posture substantially maintaining the second panel 213 parallel to the front panel 111 during the movement in a direction away from or toward the front surface 1a of the door 1 by the driving of the driving mechanism 23. This is advantageous in that the end portion of the handle body 21 in the extending direction is prevented from tilting due to uneven stress, and an effect of ensuring the synchronism and operability of the handle body 21 during switching is expected.

In practical applications, the number of drive mechanisms 23 and the specific placement locations on the handle base 22 may be adjusted as desired.

Thereby, the handle body 21 is linearly moved by the driving mechanism 23 to pop out from the surface of the door body.

In one implementation, referring to fig. 5-8 and 10, the handle assembly 2 may further include a gear 241 and a rack 242 engaged with each other, located on at least one side of the drive mechanism 23 along the extending direction (e.g., x-direction) of the handle body 21, one of which is disposed on the handle base 22, and the other of which is connected to the handle body 21.

Specifically, the gear 241 may be provided to the handle body 21, and the rack 242 may be provided to the handle seat 22. The length direction of the rack gear 242 may be parallel to the y direction, and the axial direction of the rotation shaft of the gear 241 may be parallel to the x direction.

In some embodiments, the rack 242 is fixed to the handle base 22 during movement of the handle body 21 in the y-direction and the opposite direction thereof under the drive of the drive mechanism 23, and the gear 241 rotates about an axis of rotation parallel to the x-direction relative to the handle body 21 and moves back and forth on the rack 242 in the y-direction.

Further, the handle assembly 2 may include a pair of engaged gears 241 and racks 242, and the pair of engaged gears 241 and racks 242 are symmetrically disposed at both ends of the handle body 21 in the x-direction, as shown in fig. 6. Although the rack 242 is shown on the exploded handle body 21 in fig. 6, in practical applications, the rack 242 may be fixed to the handle base 22, for example. Thereby, the synchronicity during the movement of the handle body 21 between the first position and the second position is further ensured.

In some embodiments, the number of teeth and the tooth space of the pair of racks 242 may be the same for the pair of racks 242 respectively fixed to both ends of the handle base 22 in the x-direction. Further, the patterns formed by the grooves of the pair of racks 242 may be entirely overlapped in the extending direction (e.g., x-direction) of the handle body 21. This ensures that the pair of gears 241 always move synchronously on the respective engaged racks 242, further ensuring the synchronicity of the handle body 21 during switching.

In one implementation, with continued reference to fig. 3-10, the handle assembly 2 may further include: a guide structure 25 provided on the handle base 22; the first connecting structure 26 is coupled to the guiding structure 25, and is connected to the handle body 21 and fixedly connected to the gear 241 or the rack 242 connected to the handle body 21.

As the handle body 21 is driven by the driving mechanism 23 to move in the first direction, the first connecting structure 26 is guided by the guiding structure 25 to move in the first direction, and drives the fixedly connected gear 241 or gear 242 to move on the engaged gear 242 or gear 241 toward the first direction.

One of the engaged gear 241 and rack 242 (e.g., gear 241) provided to the handle body 21 may be connected to the handle body 21 by the first connection structure 26.

The fixed connection may for example mean that the gear 241 or the rack 242 connected to the handle body 21 is brought into synchronous linear movement with the handle body 21 by means of the first connection structure 26. When the gear 241 is connected to the handle body 21, the gear 241 fixedly connected to the first connection structure 26 may also rotate relative to the first connection structure 26 while maintaining synchronous linear motion with the first connection structure 26 and the handle body 21.

Specifically, referring to fig. 9, the first connection structure 26 may include a base 261, and the base 261 may be provided with at least one first coupling hole 261a. In some embodiments, the base 261 may be secured to the handle body 21 by screws. For example, referring to fig. 8, a screw may be driven at the at least one first coupling hole 261a to fix the base 261 to the first panel 212.

Further, the first connection structure 26 may include a first coupling portion 262 provided to the base 261 for assembling the gear 241 or the rack 242.

For example, with continued reference to fig. 9, the first coupling portion 262 may extend from the base 261 in the x-direction toward the drive mechanism 23. The gear 241 may have a circular groove opened toward the base 261, and the first coupling portion 262 may protrude into the circular groove to achieve the assembly of the gear 241, as shown in fig. 10. In this example, the first coupling portion 262 may be adapted to form a rotational axis of the gear 241, and as the handle body 21 is driven by the driving mechanism 23 to move in the y-direction or the opposite direction thereof, the gear 241 rotates about the first coupling portion 262 to move on the engaged rack gear 242 toward the first direction.

Thereby, by the cooperation of the first connecting structure 26 and the guide structure 25, the movement of the handle body 21 in the y direction or the opposite direction thereof is ensured in synchronization throughout the extending direction (for example, the x direction), the swing during the movement of the handle body 21 is restricted, and the smooth movement of the handle body 21 as a whole is realized. In the scene that the length of the handle body 21 along the extending direction is larger, the movement smoothness of the handle body 21 when popping up and resetting is improved, and the phenomenon of clamping when the handle moves is avoided.

In one implementation, with continued reference to fig. 8-10, the guide structure 25 may include a guide post 252 and the first connection structure 26 may include a guide hole 263, with the guide post 252 extending in a direction parallel to the first direction (e.g., the y-direction) and protruding into the guide hole 263.

Specifically, the guide structure 25 may include a third base 251, and the third base 251 may be provided with at least one second coupling hole 251a. In some embodiments, the third base 251 may be fixed to the handle base 22 by screws. For example, referring to fig. 3, a screw may be driven at the at least one second coupling hole 251a to fix the third base 251 to the bottom wall of the recess 113.

Further, the guide post 252 may include a guide rod protruding forward in the y-direction from the third base 251, and the guide hole 263 may be opened in the base 261 and open in a direction away from the second panel 213. The axial direction of the guide hole 263 is parallel to the y-direction. At least a portion of the guide post 252 may extend into the guide hole 263 during movement of the handle body 21 between the first and second positions to substantially limit movement of the end of the handle body 21 in the x-direction to the y-direction and vice versa.

Thus, the guiding features on the guiding structure 25 and the guiding bar features on the first connecting structure 26 cooperate to function as guiding features, limiting the swing during movement of the handle body 21.

In one variation, the guide structure 25 may include a guide hole 263 axially parallel to the y-direction and open forward, and the first connection structure 26 may include a guide post 252 protruding rearward in the y-direction from the base 261. Thereby, the guiding action can also be performed during the movement of the handle body 21 between the first position and the second position.

In some embodiments, the rack 242 may be integrated with the guide structure 25, for example, the rack 242 may extend from the third base 251 in the y-direction toward a direction away from the door rear end 12. Thereby, the number of parts of the handle assembly 2 can be reduced, reducing costs and assembly complexity.

In one implementation, with continued reference to fig. 6 and 8, the first connection structure 26 may include a first connection member 26a and a second connection member 26b located at or near two ends of the handle body 21 in the extending direction (e.g., x-direction), respectively.

Specifically, the first and second connection pieces 26a and 26b may be symmetrically disposed at both ends of the handle body 21 in the x-direction. The base bodies 261 of the two connection members are respectively provided with first coupling portions 262 protruding toward each other in the x-direction to receive a pair of gears 241 symmetrically disposed at both ends of the handle body 21 in the x-direction.

Further, a pair of guide structures 25 may be symmetrically disposed at two ends of the handle seat 22 along the x direction, and the base 261 of the two connectors are each provided with a guide hole 263 extending along the y direction to receive the guide post 252 on the corresponding guide structure 25.

In this embodiment, the symmetrical arrangement may specifically mean bilateral symmetry with respect to the center line of the door body 1 in the x direction. For example, the guide structure 25 shown in fig. 10 may be adapted to be mounted to the right end recess 113 of the viewing angle gate body 11 shown in fig. 6, and the horizontally flipped structure of the guide structure 25 shown in fig. 10 may be adapted to be mounted to the left end recess 113 of the viewing angle gate body 11 shown in fig. 6.

Similarly, the first connection structure 26 shown in fig. 9 may be, for example, a first connection member 26a adapted to be mounted to the right end of the viewing handle body 21 shown in fig. 8, and the second connection member 26b may be, for example, a horizontally flipped structure of the first connection structure 26 shown in fig. 9 adapted to be mounted to the left end of the viewing handle body 21 shown in fig. 8.

In one implementation, with continued reference to fig. 5, 6 and 8, the door 1 may further include a link 13, one end of the link 13 being connected to a gear 241 or a rack 242 fixedly connected to the first link 26a, and the other end of the link 13 being connected to a gear 241 or a rack 242 fixedly connected to the second link 26 b.

Specifically, the extending direction of the link 13 may be parallel to the x-direction, and the length of the link 13 may be adapted to the distance between the first and second connection pieces 26a and 26 b.

Further, the cross section of the connecting rod 13 may be square at least at both ends. Accordingly, a pair of gears 241 coupled to the handle body 21 have square grooves opened toward each other at opposite sides thereof. The end of the connecting rod 13 is inserted into the square groove of the corresponding gear 241 to achieve the cooperation with the gear 241, connecting the left and right gears 241. Thus, the rotational movement of any one of the pair of gears 241 can be transmitted to the other one thereof through the link 13, and since the link 13 and the gears 241 are linked, the synchronous rotation of the left and right gears 241 can be ensured, thereby ensuring the synchronism of both ends of the handle body 21 during the movement.

Thereby, the overall synchronous movement of the handle body 21 is achieved, for example, such that the handle body 21 (e.g., the second panel 213) is kept in a posture movement substantially parallel to the front panel 111.

In one implementation, with continued reference to fig. 5, 6, 8 and 12, the handle assembly 2 may further include a second connection structure 27 connected to the handle body 21 and located between the first and second connection members 26a, 26b, the second connection structure 27 further being connected to the drive mechanism 23.

Specifically, the second connection structure 27 may be provided at a middle portion of the handle body 21 in the extending direction (e.g., x-direction).

Further, the second connection structure 27 may be coupled with the driving mechanism 23 to guide the driving mechanism 23 to apply a force to the middle portion of the handle body 21.

Thereby, the second connection structure 27 located at the middle of the handle body 21 in the extending direction cooperates with the first connection structure 26 located at both ends of the handle body 21, further ensuring synchronous movement of the handle body 21 everywhere in the extending direction.

In one implementation, with continued reference to fig. 3-6, 11, the drive mechanism 23 may comprise a mechanical drive mechanism, which may comprise, for example, a rebound device 231, the push rod 232 of the rebound device 231 being sprung in a first direction away from the front surface 1a of the door 1. Fig. 11 is a schematic diagram illustrating the rebound device 231 in the rebound state, where the push rod 232 is ejected forward a certain distance.

Specifically, the spring 231 may be provided with at least one third coupling hole 231a for cooperating with a screw to fix the spring 231 to the bottom wall of the recess 113.

Thereby, a mechanical actuation is achieved by means of a mechanical drive mechanism to at least enable movement of the handle body 21 from the first position to the second position, enabling ejection of the hidden handle. Further, the spring 231 itself has a locking effect, capable of holding the handle body 21 in the first position against unintended movement; when the door handle is needed, the door 1 can be opened by pressing the handle body 21 to spring a certain distance to the second position and pulling the handle body 21. The present embodiment adopts a push-type hidden handle design, is simple to operate, and provides a realization mode of the rebound type door handle to ensure the synchronism and operability of the handle body 21 in the switching process.

In one implementation, with continued reference to fig. 4 and 5, the second connection structure 27 may be connected to the handle body 21 and fixedly connected to the push rod 232. In fig. 4, a part of the second connection structure 27 is omitted, and is not fixedly connected to the push rod 232.

Specifically, the second connection structure 27 is adapted such that the push rod 232 remains in contact with the handle body 21 (e.g., the second panel 213) throughout movement of the handle body 21, as shown in fig. 5. This is advantageous in ensuring that the push rod 232 can smoothly push the handle body 21 to the second position, and in ensuring that the push rod 232 is synchronized to return to the locked state as the handle body 21 returns to the first position. Thereby, a reliable transmission of the force of the drive mechanism 23 to the handle body 21 is ensured by the second connection structure 27.

In some embodiments, with continued reference to fig. 11 and 12, the second connection structure 27 may include a third connection member 271, the third connection member 271 being formed with a connection hole 272 for the push rod 232 to pass therethrough in a first direction (e.g., y-direction), and the head of the push rod 232 may be provided with a hook 233, the hook 233 being sandwiched between the handle body 21 and the third connection member 271, as shown in fig. 5.

Specifically, the third connection member 271 may be, for example, a U-shaped member, the ends of two parallel sides of which are provided with fourth coupling holes 271a. The fourth coupling hole 271a is used for screwing to fix the third connector 271 to the handle body 21.

Further, the hollow portion between the two parallel sides and the bottom side of the U-shaped member is adapted to form a connecting hole 272. The U-shaped member may extend downwardly from the first panel 212 in the z-direction and the axis of the connection aperture 272 may be parallel to the y-direction.

Further, the hook 233 is at least sandwiched between the second panel 213 and the bottom edge of the U-shaped member, and a fixed connection between the U-shaped member and the push rod 232 is achieved.

In some embodiments, the projection of the hook 233 in the y-direction may at least partially overlap with the projection of the third connector 271 in the y-direction. When the handle body 21 is in the first position, the rebound device 231 is in the initial state, the push rod 232 is retracted and locked (as shown in fig. 6), and the hook 233 is closer to the rebound device 231 than the position shown in fig. 11. At this time, the locked push rod 232 hooks the third connector 271 rearward by the hook 233 to hold the middle portion of the handle body 21 in the extending direction at a position close to the front surface 1a of the door 1, suppressing the tendency of the middle portion of the second panel 213 to tilt forward.

Thereby, it is ensured that the handle body 21 (especially the middle part) in the first position is flush with the front surface 1a or that the handle body 21 in the first position protrudes from the front surface 1a of the door 1 parallel to the front surface 1a of the door 1.

In some embodiments, the hook 233 and the push rod 232 may be integrally formed, with high component robustness.

In some embodiments, with continued reference to fig. 4-6, 8, 11, and 12, the diameter of the connection aperture 272 may be greater than the diameter of the push rod 232. When assembled, one end of the push rod 232 provided with the hook 233 passes through the connection hole 272, and then the third connection member 271 is mounted to the first panel 212, completing the fixed connection of the push rod 232 and the handle body 21.

Further, the second connection structure 27 may further include a stopper 273 in the connection hole 272 to restrict movement of the push rod 232 in a plane perpendicular to the first direction (e.g., a plane parallel to the front surface 1a of the door 1).

For example, the connection hole 272 may be in communication with the first panel 212, the limiting portion 273 may be disposed on the second panel 213, and the limiting portion 273 extends upward to the first panel 212 along the z-direction and downward to be in surface contact with the push rod 232.

Further, an end portion of the limiting portion 273 facing away from the first panel 212 may be an upwardly concave arc surface (as shown in fig. 8), and an arc of the arc surface is adapted to an outer circumferential surface of the limiting portion 273. By the engagement of the stopper 273 and the U-shaped member, the diameter of the connection hole 272 can be reduced to be substantially equal to the diameter of the push rod 232, suppressing the movement of the push rod 232 in a plane parallel to the front panel 111.

Thereby, the push rod 232 is kept moving substantially parallel to the first direction, further limiting the swing during movement of the handle body 21.

In some embodiments, the limiting portion 273 may be integrally formed with the handle body 21.

In a variation, the shape of the connecting hole 272 may be adapted to the cross-sectional shape of the push rod 232, and the limiting portion 273 may be omitted. When assembled, one end of the push rod 232, which is not provided with the hook 233, extends into the connecting hole 272 until the hook 233 hooks the third connecting piece 271. Then, the third connector 271 is mounted to the first panel 212, completing the fixed connection of the push rod 232 and the handle body 21.

In one implementation, with continued reference to fig. 3, 4, 6 and 7, the mechanical driving mechanism may further include an elastic member 234, where two ends of the elastic member 234 along the elastic direction are respectively connected to the first connection structure 26 and the handle seat 22, where the elastic direction is parallel to the first direction (e.g., the y-direction).

Specifically, referring to fig. 7 to 9, the first connection structure 26 may be provided with a second coupling portion 264 protruding from the base 261 in a direction away from the second panel 213. The second coupling portion 264 may be used to cooperate with one end of the elastic member 234 in the elastic direction to achieve fixation.

Further, referring to fig. 7 and 10, the handle holder 22 may be provided with a third coupling portion 253 protruding from the third base 251 in a direction away from the door rear end 12. The third coupling portion 253 may be adapted to cooperate with the other end of the elastic member 234 in the elastic direction to achieve fixation.

The direction in which the second coupling portion 264 points toward the third coupling portion 253 may be parallel to the y-direction, and thus, the elastic force of the elastic member 234 may be applied to the handle body 21 almost without loss.

When the handle body 21 is in the first position, the elastic member 234 may be in a compressed state, thereby providing a supporting force at both ends of the handle body 21 in the extending direction, and the acting direction of the supporting force is opposite to the acting direction of the elastic member 231 applied to the middle portion of the handle body 21 through the hook portion 233. Thus, the handle body 21 in the first position is subjected to forces at multiple points in the extending direction and in opposite directions, further ensuring that the handle body 21 in the first position and the front panel 111 remain parallel.

In one implementation, with continued reference to fig. 4, 6 and 7, the door 1 may further include a stop mechanism 14 disposed on the handle base 22, the stop mechanism 14 being configured to limit a maximum travel of the first connection structure 26 in a direction away from the front surface 1a of the door 1.

Specifically, the stopper mechanism 14 may include an L-shaped member, one wall of which is provided with a fifth coupling hole (not shown) for screwing the L-shaped member to the bottom wall of the recess 113.

Further, the other wall of the L-shaped member protrudes upward in the z-direction from the bottom wall of the recess 113 to form a stopper wall 141.

Further, the first connection structure 26 may include a mating wall 266 extending from the base 261 in a direction away from the second connection structure 27. The engaging wall 266 may be parallel to the blocking wall 141, and as the handle body 21 moves from the first position to the second position, the first connecting structure 26 moves in the y direction from the position shown in fig. 7 to the position shown in fig. 4, at which time the engaging wall 266 is in surface contact with the blocking wall 141, the handle body 21 is restricted from continuing to move forward.

Thereby, the stopper mechanism 14 restricts the distance the handle body 21 is ejected and receives the door opening force. Further, the resilient member 234 (e.g., a spring) may assist in snapping the handle body 21 on the one hand, and may ensure that the handle body 21 and the door body 11 in the first position are parallel on the other hand, and may ensure that the handle body 21 and the detent mechanism 14 in the second position remain in contact.

In some embodiments, the second panel 213 is in surface contact with the barrier wall 141 when the handle body 21 is in the first position. Thereby, the stopper mechanism 14 can also limit the distance that the handle body 21 moves toward the door rear end 12.

In some embodiments, the second coupling portion 264 may extend outwardly from the mating wall 266.

In some embodiments, the first coupling portion 262 and the fitting wall 266 may be located at both sides of the guide hole 263 in the x-direction.

In some embodiments, the blocking wall 141 may be disposed perpendicular to the first direction (e.g., y-direction) and flush with the front surface 1a of the door 1. Thereby, the handle body 21 is stopped at the second position by the stopper wall 141. Further, it is also ensured that the handle body 21 in the second position is also parallel to the front surface 1a of the door 1.

In one implementation, with continued reference to fig. 4, 6, and 7-9, the side of the first connection structure 26 facing the barrier wall 141 may be provided with a bumper 265.

Specifically, the mating wall 266 may be provided with a receiving hole 266a recessed in a direction away from the second panel 213.

Further, the bumper 265 may include a plate body 265a and a boss 265b protruding outwardly from the plate body 265 a. The boss 265b is adapted to extend into the receiving aperture 266a to enable assembly of the bumper 265 and the first connecting structure 26.

When the handle body 21 is moved to the second position, the bumper 265 collides with the blocking wall 141 and is blocked by the blocking wall 141 from continuing the movement. For example, the surface of the plate body 265a facing the second panel 213 is in surface contact with the blocking wall 141. At least the face of the plate 265a facing the second panel 213 may be made of a non-metallic material, such as silicone rubber or the like. At this time, the impact preventing member 265 contacts the blocking wall 141 instead of the engaging wall 266, and can play a role in reducing impact and noise while reliably stopping.

In some embodiments, the receiving hole 266a and the second coupling portion 264 may be coaxially disposed. Thus, the thickness of the mating wall 266 in the y-direction may be reduced to achieve a greater distance D without increasing the dimension W2 of the recess 113 in the y-direction.

In a typical application scenario, referring to fig. 9, left and right impact members 265 may be first assembled to left and right base 261, respectively. Then, the single-sided base 261 and the handle body 21 are fixed together with screws. For example, the left base 261 is fixed to the left side of the first panel 212 in the x-direction. Then, the gear 241 is fitted to the first coupling portion 262 of the left base plate 261. Then, the left end of the link 13 and the gear 241 connected to the left base plate 261 are assembled together.

Next, a gear 241 located at the right end of the handle body 21 in the extending direction is attached to the other end (e.g., right end) of the link 13, and the right base 261 and the gear 241 are assembled together. Then, the right base 261 is also fixed to the first panel 212 with screws, resulting in the structure shown in fig. 8.

Next, the guide posts 252 on the left and right guide structures 25 are inserted into the guide holes 263 on the corresponding sides. Then, both ends of two elastic members 234 (e.g., springs) are respectively mounted in corresponding mating features of the base 261 and the third base 251 on the left and right sides, as shown in fig. 6 and 7.

Next, the left and right stopper mechanisms 14 are screwed to the handle base 22, and the rebound device 231 is screwed to the handle base 22, as shown in fig. 6. The function of the rebound device 231 is to press down, the push rod 232 on the rebound device 231 automatically pops up a certain distance, and the push rod 232 is not ejected when in the initial installation position as shown in fig. 6.

The assembled third bases 251 on the left and right sides of the handle body 21 as shown in fig. 6 are then correspondingly mounted together in mating features (e.g., the greater depth of the grooves 113 at the left and right ends) of the handle base 22. The third base 251 is fastened to the handle base 22 with screws, as shown in fig. 3.

Finally, pressing the handle body 21 causes the push rod 232 of the rebound device 231 to pop up against the second panel 213. At this time, the door 1 is turned over, and the push rod 232 of the rebound device 231 is fixed together with the handle body 21 (for example, the first panel 212) by the third connector 271 with a screw, as shown in fig. 5. To this end, the handle assembly 2 and the door body 11 are assembled.

Fig. 13 is an exploded view of the door 1 in a variation of the embodiment of the present utility model. Only the differences between the embodiment shown in fig. 13 and the embodiments shown in fig. 1 to 12 described above will be described.

In a variation of the above embodiment, referring to fig. 13 to 18, the driving mechanism 23 may include a motor driving mechanism, which may include, for example, a motor 235 and a transmission gear 236 and a transmission rack 237 engaged with each other, the transmission gear 236 being coaxially connected with the motor 235.

Specifically, motor 235 may include a rotating electric machine. In some embodiments, the axial direction of the motor shaft of the rotating electrical machine may be parallel to the x-direction. Further, the motor shaft of the motor 235 is adapted to form a rotation shaft of the transmission gear 236.

Further, the drive rack 237 may be directly or indirectly connected to the handle body 21.

In some embodiments, the length direction of the drive rack 237 may be parallel to the y-direction, and the axis of rotation of the drive gear 236 may be parallel to the x-direction. When the motor 235 rotates, the transmission gear 236 is driven to rotate, and the rotation motion of the transmission gear 236 is changed into the linear motion of the transmission rack 237 along the y direction, so as to drive the handle body 21 to linearly move along the y direction.

In some embodiments, the drive rack 237 may be located below the drive gear 236 in the z-direction.

Thereby, the motor drive mechanism is electrically operated to move at least the handle body 21 from the first position to the second position, thereby realizing the ejection of the hidden handle. Further, the handle body 21 is automatically driven to pop up by the electric control so that the user pulls the automatically popped-up handle body 21 to open the door 1. Therefore, the user can open the door 1 by only one-step action, so that the operation steps of the user are simplified, and the operation experience of the user is further optimized. Further, the safety is high, the appearance is attractive, and the ergonomics are more met.

Further, by controlling the reverse rotation of the motor 235, the handle body 21 can be automatically controlled to linearly move from the second position (the pop-up state shown in fig. 2) back to the first position (the hidden state shown in fig. 1). Therefore, the operation of a user when opening and closing the door 1 is the same as the operation of opening and closing the existing door without the hidden door handle, and the user operation experience is further improved.

In one implementation, with continued reference to fig. 14 and 17, the second connection structure 27 may include a fourth connection 274 connected to the handle body 21 and fixedly connected to the drive rack 237. That is, the drive rack 237 may be connected to the handle body 21 by the fourth connection 274.

Specifically, the fourth connecting member 274 may include a fourth coupling portion 275, and the fourth coupling portion 275 may be connected to an end of the drive rack 237 adjacent to the handle body 21 in the length direction (e.g., parallel to the y-direction) by screwing or the like. Thus, the fourth connecting member 274 is fixedly connected to the driving rack 237, and the driving rack 237 is driven by the motor 235 to move linearly in the y direction or the opposite direction by the rotating driving gear 236, so as to push the second connecting structure 27 to move linearly back and forth.

Further, the fourth connecting member 274 may be provided with at least one sixth coupling hole 274a for fixedly connecting the fourth connecting member 274 and the handle body 21. For example, the fourth connecting member 274 and the second panel 213 may be fixedly coupled by screwing.

In some embodiments, the drive gear 236 and most of the drive rack 237 are located rearward of the second attachment structure 27 in the thickness direction of the door 1. Thereby, part of the structure of the motor driving mechanism is shielded by the second connection structure 27, and the front surface of the door 1 is more compact and beautiful.

In one implementation, with continued reference to fig. 15 and 17, the motor drive mechanism may further include a slider 238 secured to the handle base 22, the slider 238 defining a slot 238a along a first direction (e.g., the y-direction), and a drive rack 237 at least partially disposed within the slot 238a and movable along the slot 238a in the first direction. Thus, the slide slot 238a acts as a guide ensuring that the direction of movement of the drive rack 237 is substantially parallel to the first direction (e.g., the y-direction).

Specifically, a pair of side walls of the drive rack 237 opposite in the y-direction may be provided with a concave-convex structure to be engaged with the slide groove 238 a.

When the motor 235 rotates, the transmission gear 236 is driven to rotate, and the transmission gear 236 drives the transmission rack 237 to move on the sliding block 238, so that the fourth connecting piece 274 and the handle body 21 are driven to move. By providing the extending direction of the chute 238a parallel to the y-direction, the moving direction of the handle body 21 during the foregoing movement can be substantially limited to the y-direction and the opposite direction.

In a variation of the above embodiment, with continued reference to fig. 13, 14 and 18, the handle base 22 may be a separate piece and secured to the recess 113.

Specifically, the handle seat 22 may be fixed to the recess 113 by means of a fixing member, an interference fit, an adhesive, or the like. For example, the handle holder 22 may be fixed to the groove 113 by a screw. Therefore, the handle assembly 2 can be directly detached from the door body 11 when needed, and after-sales maintenance is convenient.

Further, the handle base 22 may be provided with a first base 221, and the motor 235 may be fixed to the first base 221 by screws. For example, the motor 235 is provided with fifth coupling parts 235a at both sides in the y-direction, respectively, and the fifth coupling parts 235a include screws to be engaged with screw holes on the first base 221. In some embodiments, first base 221 may have an upwardly open receiving cavity to receive at least a portion of motor 235.

Further, the handle base 22 may include a second base 222, and the slider 238 may be assembled and fixed to the second base 222. For example, the slider 238 may be secured to the second base 222 by a snap fit, interference fit, adhesive, or the like. In some embodiments, the second base 222 may have an upwardly open receiving cavity to receive the slider 238.

In some embodiments, the first base 221 and the second base 222 may be disposed adjacent. For example, both may be juxtaposed in the x-direction.

In some embodiments, the handle base 22 may be a single piece or may be assembled from multiple pieces.

In some embodiments, with continued reference to fig. 14, the front panel 111 is adapted to shield at least a portion of the handle base 22 from the front. Further, the front panel 111 is adapted to form a front wall of the recess 113. Thus, the front surface of the refrigerator 100 covers the handle base 22 together with the front panel 111 and the second panel 213, and the refrigerator 100 is more beautiful as a whole. Further, when the handle body 21 is located at the first position, the second panel 213 may be flush with the front panel 111, and the two panels may be arranged up and down along the z direction.

In some embodiments, the handle base 22 may have an upwardly facing opening to facilitate mounting of the motor drive mechanism, the first connecting structure 26, and the guide structure 25, among other components. The upwardly facing opening may extend substantially in the x-direction to the end of the handle base 22.

Further, the handle base 22 may also have a forward opening to avoid the need for forward and backward movement of the components provided to the handle base 22. For example, the forward opening is disposed at least in front of the fourth link 274, and the fourth link 274 can continue to move forward in the y-direction from the forward opening under the pushing of the driving rack 237, so as to drive the handle body 21 to the second position. Similarly, the fourth connecting member 274 can return to the area surrounded by the handle seat 22 from the front opening under the driving of the driving rack 237, so as to drive the handle body 21 to return to the first position.

Further, the handle holder 22 may be provided with guide grooves 223 extending in the y-direction at both sides of the rack gear 242 in the x-direction, and the end of the link 13 connected to the gear 241 and a part of the structure of the first connection structure 26 connected to the gear 241 may move back and forth within the corresponding guide grooves 223. The forward opening may communicate with the guide slot 223 to provide a relief effect.

In a variation of the above embodiment, with continued reference to fig. 13 and 14, the handle assembly 2 may further include a cover 28 for closing the upwardly facing opening of the handle base 22. Specifically, the cover 28 may be located between the handle base 22 and the first panel 212. Thus, when the handle body 21 moves to the second position, the parts provided on the handle seat 22 are covered by the cover plate 28 and are not exposed, so that the door 1 has a more attractive appearance when the handle body 21 is in the ejected state. For example, when the door 1 is opened, the cover 28 is seen from above through the gap between the handle body 21 and the door rear end 12, instead of the numerous component structures on the handle base 22, and the aesthetic appearance of the door 1 is optimized. Further, the cover plate 28 can function to prevent foreign matter from entering the handle seat 22, and prevent foreign matter such as dust, liquid, etc. from entering the handle seat 22 from a gap between the handle body 21 and the door rear end portion 12 from affecting the performance of the drive mechanism 23.

In one variation of the above embodiment, with continued reference to fig. 14 to 16, the guide structure 25 may include a pair of fixing portions 254 disposed opposite to each other in the y-direction, and both ends of the guide post 252 in the extending direction are connected to the pair of fixing portions 254, respectively.

Further, a pair of fixing portions 254 may be respectively mounted to opposite side walls of the handle base 22 in the y-direction. For example, the opposite side walls of the handle base 22 in the y-direction may be provided with mounting holes 224 for receiving corresponding securing portions 254.

In some embodiments, the forward of the pair of fixtures 254 in the y-direction 254, and the side wall of the handle base 22 to which the fixtures 254 are mounted, may act as a stop mechanism 14 for limiting continued forward movement of the first connection structure 26.

In one variation of the above embodiment, with continued reference to fig. 14-16, the first connection structure 26 may be fixedly connected to the second panel 213 through at least one first coupling hole 261 a. By providing the rack gear 242 at both ends of the handle holder 22 in the extending direction, the gear 241 moves on the rack gear 242 while the gear 241 at both ends is connected to the first connection structure 26, respectively, and the first connection structure 26 slides on the guide post 252 and is connected to the handle body 21. Thereby, the synchronism of the movement of both ends of the handle body 21 in the x direction is further ensured.

In a variation of the above embodiment, with continued reference to fig. 14 and 18, the rack 242 may be integrally formed with the handle base 22.

In one implementation, the door 1 may further comprise: a sensing device 15 provided to the door 1 and/or a compartment (e.g., a storage compartment) of the refrigerator 100, the sensing device 15 being for sensing whether a human body approaches or leaves the door 1; and a control module (not shown) is disposed in the refrigeration appliance 100, and is respectively in communication with the sensing device 15 and the motor driving mechanism, and the control module is used for controlling the motor driving mechanism to operate according to the sensing result of the sensing device 15.

Specifically, the sensing device 15 may be, for example, a human body proximity sensor, an infrared sensor, a distance sensor, or the like. In some embodiments, the sensing device 15 may be disposed behind the front panel 111.

Further, the control module may include a controller of the refrigerator appliance 100, or the control module may include a control unit dedicated to controlling the ejection or reset of the handle body 21, independently of the controller.

For example, when a user approaches refrigerator appliance 100, sensing device 15 detects the presence of the user and sends a first control signal to motor 235. In response to receiving the first control signal, the motor 235 drives the transmission gear 236 to rotate, the transmission gear 236 drives the transmission rack 237 to move forward along the chute 238a, and the fourth link 274 fixed to the transmission rack 237 pushes the handle body 21 to move forward to the second position. At this time, the user may pull the handle body 21 automatically popped up to open the door 1.

For another example, when the user closes the door 1 and leaves, the sensing device 15 does not detect the presence of the user and sends a second control signal to the motor 235. In response to receiving the second control signal, the motor 235 drives the drive gear 236 to rotate, the drive gear 236 drives the drive rack 237 to move rearward along the chute 238a, and the fourth link 274, to which the drive rack 237 is fixed, pulls the handle body 21 back to the first position. If the handle body 21 is pushed directly when the door 1 is closed, the handle body 21 may not be fully restored to the first position, and the present example ensures that the handle body 21 is fully restored to the hidden state by detecting the departure of the human body to control the movement of the motor 235.

In some embodiments, a plurality of doors 1 of the refrigerator 100 may each be provided with the handle assembly 2 described above. In this example, the control module may control the handle body 21 of each door 1 of the plurality of doors 1 to be simultaneously rotated to pop up in response to the sensing device 15 sensing the approach of the human body.

Alternatively, in this example, the sensing device 15 may further include a gesture sensor, and the control module first controls the handle body 21 of each door 1 of the plurality of doors 1 to remain in the first position when the approach of the user is detected. In response to the gesture sensor detecting a gesture operation of the user with respect to the door 1 to be opened, the control module controls the handle body 21 of the door 1 to rotate and pop up. At this time, the handle body 21 of the other door 1 among the plurality of doors 1 is still maintained at the first position.

In some embodiments, the sensing device 15 may further include a negative pressure sensor disposed in the storage chamber, and the negative pressure sensor is configured to detect a negative pressure value in the storage chamber. Since the difference in the negative pressure value in the storage chamber is large when the door 1 is opened and closed, the present embodiment can more precisely recognize whether the door 1 is closed, and thus more precisely control the timing at which the motor 235 moves to drive the handle body 21 to return to the first position.

From this, through the approach or leave of the human body of response, the timing of intelligent control handle body 21 autogiration pops out and automatic re-setting, the user need not to carry out extra operation to handle body 21 when switch door 1, and the operation experience is better. Specifically, the user operation steps are simplified by adding the sensing device 15 in combination with the motor driving mechanism, while satisfying the required safety and aesthetic requirements.

In a common variation of the above embodiment, the number of the driving mechanisms 23 may be plural and provided at both ends of the handle assembly 2 in the extending direction, respectively. Synchronous motors can also be respectively designed at two ends of the hidden handle assembly 2 so as to simplify the mechanical structure in the handle assembly 2.

Further, the engaged gear 241 and rack 242, the guide structure 25, and the first connection structure 26 may be disposed at a middle portion of the handle assembly 2 in the x-direction.

From the above, this embodiment provides a hidden door handle, and the handle body 21 that is located the first position when not using at ordinary times is hidden at the door body 11, because most structures do not expose in the surface of the door body, therefore compare the external handle that the door of present refrigeration utensil adopted safer also more pleasing to the eye. When the door 1 needs to be opened and closed, the handle body 21 moves from the first position to the second position to pop out from the surface of the door body, at this time, the handle body 21 is formed as a grip portion for gripping, and an operation space 211 for the hand to extend is formed between the handle body 21 and the door rear end portion 12. In the multi-door refrigerator scenario, compared with the built-in handle adopted by the door of the existing refrigerator in the side frame, the space between the left and right doors 1 can be made small because the handle body 21 is ejected forward, so that the appearance of the refrigerator 100 is more attractive.

Further, since the handle body 21 can be moved between the first position and the second position, in order to achieve smooth movement of the handle body 21, and in order to enable the handle body 21 in the second position to protrude from the front panel 111 by a distance to provide a sufficient operation space 211 for a user, the recess 113 in which the handle assembly 2 is installed needs to have a certain thickness. Further, the greater the thickness W2 of the recess 113, the less structural requirements are placed on the handle assembly 2, and the more stable the drive mechanism 23 for driving movement of the handle body 21 will operate. On the other hand, the heat insulating performance of the door body 11 at the handle assembly 2 is also required, and the heat insulating layer cannot be provided right behind the groove 113, otherwise the heat insulating performance at the handle assembly 2 is poor, and dew is easily generated at the handle assembly 2. Thus, the present embodiment can provide a sufficient handle operation space and achieve smooth movement of the handle, and the handle assembly 2 is not easily exposed by rationally designing the respective dimensions of W1 and W2 and the size relationship with each other.
