One side of the first rotating bracket 112 and one side of the second rotating bracket 114 are respectively hinged to the support 146, and the other side of the first rotating bracket 112 and the other side of the second rotating bracket 114 are respectively hinged to the cover plate assembly 108. Thus, the cover plate assembly 108 may act against the seat 146 under the hinging action of the first and second

rotational supports

112, 114.

The driving device 104 may be connected to the first rotating bracket 112 or the second rotating bracket 114, respectively, or the driving device 104 may be connected to both the first rotating bracket 112 and the second rotating bracket 114. The driving device 104 can drive the first rotating bracket 112 and/or the second rotating bracket 114 to rotate, so as to drive the cover plate assembly 108 to move relative to the support 146. In the embodiment of the present invention, the first rotating bracket 112 and the second rotating bracket 114 can drive the cover plate assembly 108 to move along a direction perpendicular to the door body 100, and it can be understood that the cover plate assembly 108 can translate relative to the door body 100 in a direction perpendicular to the door body 100.

Since the hinge point of the first driving shaft 122 and the support 146 and the hinge point of the second driving shaft 128 and the support 146 are fixed points, and the relative distance between the two hinge points and the inclination angle of the connecting line of the two hinge points are also fixed, the distances between the hinge point of the first driven shaft 124 and the cover plate assembly 108 and the hinge point of the second driven shaft 130 and the cover plate assembly 108 are also equal, and the connecting lines between the hinge point of the first driven shaft 124 and the cover plate assembly 108 and the hinge point of the second driven shaft 130 and the cover plate assembly 108 are also parallel to the connecting line between the hinge point of the first driving shaft 122 and the support 146 and the hinge point of the second driving shaft 128 and the support 146, so that the cover plate assembly 108 can realize the up-and-down translation as shown in fig. 7, 8 or 9 along the direction perpendicular to the door body 100.

It should be noted that, as shown in fig. 7 to 9, in the process of moving the cover assembly 108 from the position covering the handle slot 102 to the position avoiding the handle slot 102, the cover assembly 108 translates downward by a distance of about 1 mm to 3 mm as shown in fig. 8, then translates rightward by a distance of about 1 mm to 3 mm as shown in fig. 9, and finally moves to the position avoiding the handle slot 102 as shown in fig. 9. Similarly, in the process of moving the cover assembly 108 from the position avoiding the handle slot 102 to the position shielding the handle slot 102, the cover assembly 108 translates downward by a distance of about 1 mm to 3 mm as shown in fig. 8, then translates leftward by a distance of about 1 mm to 3 mm as shown in fig. 7, and finally moves to the position shielding the handle slot 102 as shown in fig. 7.

Note that the width of the first link 126 and the width of the second link 132 need not be equal to the length of the first drive shaft 122 and the second drive shaft 128, and may be set to connect the first drive shaft 122 and the first driven shaft 124 and the second drive shaft 128 and the second driven shaft 130. In addition, in some embodiments of the present invention, the positions of the first connecting member 126 and the second connecting member 132 in the space width direction are staggered to avoid interference between the two during rotation.

In other embodiments, the first and second

rotating brackets

112 and 114 may be provided in the form of rectangular frames, that is, in this implementation, the first and second

rotating brackets

112 and 114 may not be provided with a driving shaft, a driven shaft and corresponding connectors, but may be replaced by an integrally formed rectangular frame structure.

According to one embodiment of the present invention, the lid assembly 108 includes a lid base 142 and a lid body 144; both ends of the first driven shaft 124 and both ends of the second driven shaft 130 are respectively hinged to the cover plate base 142; the cover body 144 is mounted to the cover base 142.

Referring to fig. 3, 7 to 9, the two ends of the first driven shaft 124 and the second driven shaft 130 are hinged to the cover base 142, the cover base 142 is further provided with a cover body 144, and the cover body 144 and the cover base 142 can be fixed in a bonding manner, a clamping manner, or the like. In other words, when the driving device 104 drives the first rotating bracket 112 and/or the second rotating bracket 114 to operate, the first rotating bracket 112 and the second rotating bracket 114 can drive the cover base 142 and the cover body 144 to switch between a position of avoiding the handle slot 102 and a position of shielding the handle slot 102. In addition, the cover body 144 may be made of the same material as the outer surface of the door body 100, which can further improve the uniformity of the appearance of the outer surface of the door body 100.

With continued reference to fig. 3, in the embodiment of the present invention, the door assembly for a refrigerator further includes a light bar 148 and a lampshade 150 covering the light bar 148. Light bar 148 is removably mounted to support 146 and light housing 150 is snap-fitted to light bar 148. Of course, in other embodiments, the light bar 148 can also be directly installed under the cover body 144 and follow the cover body 144 to move synchronously.

By arranging the light bar 148 on the support 146, when a human body approaches the door body 100, the light bar 148 can illuminate the position of the cover plate assembly 108, so that a user can accurately know the specific position of the cover plate assembly 108. When the door 100 is closed, the light bar 148 is automatically turned off.

Referring to fig. 3 to 6, in the embodiment of the present invention, the first detecting element 134 is installed on the door 100 and/or the bracket, and the first detecting element 134 may be used to detect whether a human body approaches, and may also be used to detect an open/close state of the door 100 or to detect whether a user leaves, and when the first detecting element 134 detects that the above situation occurs, the first detecting element 134 may generate a first detecting signal for controlling the driving device 104.

Specifically, when the first detecting element 134 detects that a human body approaches, the characteristic user has a request for opening the door, and the first detecting element 134 is configured to generate a first detection signal indicating that the door body 100 is opened. After the driving device 104 receives the first detection signal, the driving device 104 may switch the first rotating bracket 112 and/or the second rotating bracket 114 from the reset state to the pressing state.

When the door body 100 is switched from the open state to the closed state, the first detection piece 134 may detect the motion of the door body 100 to generate a first detection signal representing that the door body 100 is closed; alternatively, when the user leaves, the first detecting element 134 may detect that the human body has left the vicinity of the door body 100 to generate a first detection signal indicating that the door body 100 can be closed. When the driving device 104 receives the first detection signal, the driving device 104 may switch the first rotating bracket 112 and/or the second rotating bracket 114 from the pressed state to the reset state.

It should be noted that, the first detecting element 134 may select a sensor (e.g., an infrared sensor or a laser sensor) for detecting a distance between a human body, a sensor for detecting a biological characteristic of a human body, such as a face recognition device or a voice recognition device, or a pressure sensor, and the first detecting signal is generated when a user touches a certain area of the door body 100, that is, the type and the excitation manner of the first detecting element 134 are not particularly limited in the present invention, as long as the door opening requirement and the door closing requirement of the user can be determined.

Several arrangements of the driving device 104 according to the embodiment of the present invention are described below:

the setting mode is as follows:

the driving device 104 includes a motor, the motor is mounted on the door body 100 or on the support 146, and the motor is connected with the first driving shaft 122 and/or the second driving shaft 128.

For example, in this arrangement, the motor may be connected to the first driving shaft 122, so that when the door 100 is in the closed state, and the first detecting element 134 detects that a human body approaches, it indicates that the user has a request to open the door, and the first detecting element 134 is configured to generate a first detection signal indicating that the door 100 is open. The motor drives the first driving shaft 122 to move, so that the first rotating bracket 112 is switched from the reset state to the pressing state, and at this time, the user can buckle the handle slot 102 to open the door body 100. When a user leaves or closes the door body 100, the first detection part 134 can generate a first detection signal, the motor drives the first driving shaft 122 to rotate based on the first detection signal, and then the first rotating bracket 112 is driven to be switched from the pressing state to the resetting state, and meanwhile, the second rotating bracket 114 is driven by the first rotating bracket 112 to be switched from the pressing state to the resetting state synchronously.

Of course, the motor may be connected to the second driving shaft 128 to drive the second driving shaft 128 by the motor, so that the second rotating bracket 114 is switched from the pressed state to the reset state.

Or two motors can be further provided, the two motors are respectively connected with the first driving shaft 122 and the second driving shaft 128, and one of the motors is used for driving the first driving shaft 122, so that the first rotating bracket 112 can be switched from the pressing state to the resetting state; another motor is used to drive the second driving shaft 128 so that the second rotating bracket 114 can be switched from the reset state to the pressed state.

The setting mode is two:

the driving device 104 includes a motor and an elastic member 120; the motor is connected with the first driving shaft 122 and/or the second driving shaft 128; the elastic element 120 is sleeved on the first driving shaft 122, and two ends of the elastic element 120 are respectively abutted against the support 146 and the first connecting element 126; and/or the elastic element 120 is sleeved on the second driving shaft 128, and two ends of the elastic element 120 are respectively abutted against the support 146 and the second connecting element 132.

In this configuration, the motor is connected to the first driving shaft 122, and the elastic element 120 is sleeved on the first driving shaft 122.

The motor is connected to the first driving shaft 122 in a transmission manner, the elastic element 120 may be a torsion spring, the torsion spring is sleeved on the first driving shaft 122, and two ends of the torsion spring respectively abut against the support 146 and one side of the first connecting element 126 facing the inner surface of the door body 100.

Thus, when the door body 100 is in the closed state and the user is close to the door body 100, the first detection part 134 can control the motor to act, the motor drives the first driving shaft 122 to rotate so that the bracket is switched from the reset state to the pressing state, at this time, the user can buckle the handle slot 102 to open the door body 100, and meanwhile, the torsion spring is screwed. When the user leaves or closes the door body 100, the torsion spring drives the first driving shaft 122 to rotate reversely under the action of the torsion restoring force of the torsion spring, so as to drive the first rotating bracket 112 to be switched from the pressing state to the resetting state, and meanwhile, the second rotating bracket 114 is synchronously switched from the pressing state to the resetting state under the drive of the first rotating bracket 112.

Alternatively, the motor is connected to the first driving shaft 122, the torsion spring is sleeved on the first driving shaft 122, and two ends of the torsion spring respectively abut against the support 146 and one side of the first connecting piece 126 facing the outer surface of the door body 100.

Thus, when the door body 100 is in the closed state, the torsion spring is in the state of being screwed, the motor stops not rotating and is balanced with the torsion restoring force of the torsion spring, when the user is close to the door body 100, the first detection piece 134 can control the motor to act so as to loosen the torsion spring, the torsion spring drives the first driving shaft 122 to rotate under the action of the torsion restoring force of the torsion spring, so that the first rotating bracket 112 is switched to the pressing state from the resetting state, and at the moment, the user can buckle the handle slot 102 to open the door body 100. When the user leaves or closes the door 100, the motor rotates reversely and drives the first driving shaft 122 to rotate so as to overcome the torsional restoring force applied by the torsion spring to the first connecting member 126, and further drives the first rotating bracket 112 to switch from the pressing state to the resetting state, and meanwhile, the second rotating bracket 114 is driven by the first rotating bracket 112 to switch from the pressing state to the resetting state synchronously. It should be noted that, in the process of switching the stand from the reset state to the pressed state, the control of the operating speed of the first rotating stand 112 can be realized by controlling the rotating speed of the motor, so as to realize the smooth operation of the cover body 144, and in the process of switching the stand from the pressed state to the reset state, the control of the rotating speed of the motor can also realize the smooth operation of the cover body 144.

In other words, in this arrangement, the support can be switched from the reset state to the pressed state by the motor driving the support, and from the pressed state to the reset state by the torsion spring driving the support; or the support is driven by the motor to be switched from the pressing state to the resetting state, and the support is driven by the torsion spring to be switched from the resetting state to the pressing state.

In addition, in this arrangement, the motor may be connected to the first driving shaft 122, the torsion spring is sleeved on the second driving shaft 128, and two ends of the torsion spring respectively abut against the support 146 and one side of the second connecting member 132 facing the inner surface of the door body 100. In this way, the first rotating bracket 112 can be driven by the motor to switch from the reset state to the pressed state, and the second rotating bracket 114 can be driven by the torsion spring to switch from the pressed state to the reset state.

Or the motor is connected to the first driving shaft 122, the torsion spring is sleeved on the second driving shaft 128, and two ends of the torsion spring respectively abut against the support 146 and one side of the second connecting member 132 facing the outer surface of the door body 100. In this way, the first rotating bracket 112 can be driven by the motor to switch from the pressed state to the reset state, and the second rotating bracket 114 can be driven by the torsion spring to switch from the reset state to the pressed state.

Or the motor is connected to the second driving shaft 128, the torsion spring is sleeved on the first driving shaft 122, and two ends of the torsion spring are respectively abutted against the support 146 and one side of the first connecting piece 126 facing the inner surface of the door body 100. In this way, the second rotating bracket 114 can be driven by the motor to switch from the reset state to the pressed state, and the first rotating bracket 112 can be driven by the torsion spring to switch from the pressed state to the reset state.

Or the motor is connected with the second driving shaft 128, the torsion spring is sleeved on the first driving shaft 122, and two ends of the torsion spring are respectively abutted against the support 146 and one side of the first connecting piece 126 facing the outer surface of the door body 100. In this way, the first rotating bracket 112 can be driven by the motor to switch from the reset state to the pressed state, and the second rotating bracket 114 can be driven by the torsion spring to switch from the reset state to the pressed state.

Or the motor is connected to the second driving shaft 128, the torsion spring is sleeved on the second driving shaft 128, and two ends of the torsion spring are respectively abutted against the support 146 and one side of the second connecting piece 132 facing the inner surface of the door body 100. In this way, the second rotating bracket 114 can be driven by the motor to switch from the reset state to the pressed state, and the second rotating bracket 114 can be driven by the torsion spring to switch from the pressed state to the reset state.

Or the motor is connected with the second driving shaft 128, the torsion spring is sleeved on the second driving shaft 128, and two ends of the torsion spring are respectively abutted against the support 146 and one side of the second connecting piece 132 facing the outer surface of the door body 100. In this way, the second rotating bracket 114 can be driven by the motor to switch from the pressed state to the reset state, and the second rotating bracket 114 can be driven by the torsion spring to switch from the reset state to the pressed state.

Or the motor is connected to the first driving shaft 122 and the second driving shaft 128, and simultaneously, torsion springs are provided on both the first driving shaft 122 and the second driving shaft 128. The motor is used for simultaneously driving the first driving shaft 122 and the second driving shaft 128 to switch from the reset state to the pressed state, and accordingly, the torsion spring simultaneously drives the first driving shaft 122 and the second driving shaft 128 to switch from the pressed state to the reset state. Or a motor for simultaneously driving the first and

second driving shafts

When power is off, if the bracket is in the reset state, the user can manually press the cover assembly 108 to switch the cover assembly 108 from the reset state to the pressed state, so as to operate the handle slot 102 to open the door body 100.

The setting mode is three:

the drive means 104 comprises a magnetic member mounted to the seat 146, the magnetic member being adapted to drive the seat between the depressed state and the reset state based on the first detection signal.

In this arrangement, the magnetic member may be an electromagnet, and two electromagnets may be provided, wherein one electromagnet is used for driving the bracket to switch from the reset state to the pressing state, and the other electromagnet is used for driving the bracket to switch from the pressing state to the reset state.

Therefore, when the door body 100 is in the closed state, after one of the electromagnets receives a first detection signal for characterizing opening of the door, the electromagnet is powered on and generates a magnetic force on the first rotating bracket 112 and/or the second rotating bracket 114, so as to drive the brackets to be switched from the reset state to the pressing state, and at this time, a user can buckle the handle slot 102 to open the door body 100. When the user leaves or closes the door body 100, the electromagnet is powered off, the other electromagnet is powered on, and generates a magnetic force on the first rotating bracket 112 and/or the second rotating bracket 114, so as to drive the first rotating bracket 112 and/or the second rotating bracket 114 to be switched from the pressing state to the resetting state.

The setting mode is four:

the driving device 104 comprises a magnetic member and an elastic member 120, the magnetic member is mounted on the seat 146, the elastic member 120 is adapted to drive the stand to switch from the reset state to the pressing state, and the magnetic member is adapted to drive the stand to switch from the pressing state to the reset state.

Alternatively, the magnetic member is adapted to drive the stand to switch from the reset state to the pressed state, and the elastic member 120 is adapted to drive the stand to switch from the pressed state to the reset state.

According to an embodiment of the present invention, the door assembly for a refrigerator further includes a second detector 136, the second detector 136 being mounted to the supporter 146, the second detector 136 being adapted to generate a second detection signal for controlling the motor to be stopped when detecting that the supporter is moved to the reset state.

In the first and second embodiments, the second detecting member 136 is further disposed on the support 146, and the second detecting member 136 may be a detecting member such as a micro switch or a proximity switch. The second detecting member 136 is provided to detect the position of the cradle and generate a second detection signal when the cradle moves from the pressed state to the reset state by the second detecting member 136. In the first and third embodiments, when the motor is used to drive the holder to switch from the pressed state to the reset state, the motor can be stopped based on the second detection signal.

In other words, when the motor-driven bracket is switched from the pressed state to the reset state, the second detecting member 136 is triggered and generates the second detecting signal, and the motor stops after receiving the second detecting signal, so that the bracket can stay in the reset state.

Referring to fig. 3 to 6, the first driving shaft 122 and/or the second driving shaft 128 are/is sleeved with a swing link 140, and in the reset state, the swing link 140 is adapted to trigger the second detecting element 136 so that the second detecting element 136 generates the second detecting signal.

Specifically, for example, the swing link 140 is connected to the first driving shaft 122, a flat hole may be formed on the swing link 140 and sleeved on the first driving shaft 122, and a swing arm may be formed on the swing link 140, wherein the swing arm includes a first swing arm and a second swing arm. When the motor drives the first driving shaft 122 to rotate and drives the first rotating support 112 to be switched from the pressing state to the resetting state, the first swing arm on the swing rod 140 can trigger the second detection part 136, the second detection part 136 generates a second detection signal immediately, the motor stops after receiving the second detection signal, and at this time, the support can be kept in the resetting state.

Referring to fig. 3, in the embodiment of the present invention, a third detecting member 138 is further disposed on the door 100, wherein the third detecting member 138 may also be mounted on the support 146, and the third detecting member 138 may be a detecting member such as a micro switch or a proximity switch. The third detecting member 138 is configured such that the third detecting member 138 detects the position of the cradle and generates a third detecting signal when the cradle moves from the reset state to the pressed state. In the first and third embodiments, when the motor is used to drive the holder to switch from the reset state to the pressed state, the motor may be stopped based on the third detection signal.

Likewise, in the pressed state, the rocker 140 is adapted to trigger the third detection member 138 to generate a third detection signal. Specifically, for example, the swing link 140 is connected to the first driving shaft 122, a flat hole may be formed in the swing link 140 and sleeved on the first driving shaft 122, when the motor drives the first driving shaft 122 to rotate and drives the first rotating bracket 112 to switch from the reset state to the pressing state, the second swing arm on the swing link 140 may trigger the third detecting element 138, the third detecting element 138 generates a third detecting signal immediately, the motor stops after receiving the third detecting signal, and at this time, the bracket may be kept in the pressing state.

In the embodiment of the present invention, the second detecting element 136 and the third detecting element 138 may not be provided, and the control manner of the motor for the first rotating bracket 112 and/or the second rotating bracket 114 may be adjusted only by setting the operation time of the motor.

For example, the operation time of the motor may be set to be automatically stopped after the second of operation, for example, when the motor drives the first rotating bracket 112 to be switched from the reset state to the pressing state and the foreign object is stuck, the motor is automatically stopped after the second of operation, and after the foreign object is taken out, the cover plate body 144 may be manually pressed to move the bracket to the pressing state, so that the occurrence of the situation that the motor is damaged due to a large torque applied to the motor can be effectively avoided. Of course, the above-mentioned seconds are only illustrative examples, and for example, the operation time of the motor may be optional within the interval of up to seconds.

In addition, by setting the operation time of the motor to the preset time, the motor can be automatically stopped after the operation time reaches the preset time, so that the second detecting member 136 and the third detecting member 138 can be omitted, and the design and manufacturing cost can be further reduced. In addition, the user can also keep the support in a pressing state according to actual use requirements, so that the user can conveniently open the door body 100 at any time. Accordingly, the aim of keeping the bracket in a pressing state can be achieved through the control of the motor.

In other embodiments, in combination with the above description, a motor, a torsion spring, a magnetic member, and the like may be directly connected to the first rotating bracket 112 and the second rotating bracket 114 in the shape of a rectangular frame.

The following description is provided with respect to the clutch mechanism 110 according to an embodiment of the present invention:

as shown in fig. 6 and 14, according to one embodiment of the present invention, the clutch mechanism 110 includes driving teeth 116, driven teeth 118, and an elastic member 120; wherein, the driving tooth 116 is mounted on the first rotating bracket 112 and/or the second rotating bracket 114 to be in transmission connection with the driving device 104; the driven teeth 118 are fixed to the first rotating bracket 112 and/or the second rotating bracket 114 on which the driving teeth 116 are mounted; the elastic member 120 is sleeved on the first rotating bracket 112 and/or the second rotating bracket 114 on which the driving tooth 116 is mounted, and the elastic member 120 is adapted to abut against a side of the driven tooth 118 away from the driving tooth 116, so that the driven tooth 118 is engaged with the driving tooth 116.

In an embodiment of the present invention, a shaft sleeve 152 may be fixedly disposed on the first driving shaft 122, the driving gear 116 may be rotatably disposed on the shaft sleeve 152, and a driven gear 118 engaged with the driving gear 116 is fixedly disposed on the first driving shaft 122. Note that the driven teeth 118 mentioned herein are fixedly provided on the first drive shaft 122, which means that the driven teeth 118 can rotate in synchronization with the first drive shaft 122 but can slide in the axial direction thereof with respect to the first drive shaft 122. An elastic member 120 is disposed on a side of the driven gear 118 away from the driving gear 116, an axial position of one end of the elastic member 120 relative to the first driving shaft 122 is fixed, and the other end of the elastic member 120 abuts against a side of the driven gear 118 away from the driving gear 116, where the elastic member 120 may be a spring, a torsion spring, or the like. Thus, the driven teeth 118 are always pressed against the driving teeth 116 by the elastic force of the elastic member 120 to realize the meshing transmission with the driving teeth 116.

Taking the driving device 104 comprising a motor as an example, when the gear on the output shaft of the motor is in meshing transmission with the driving gear 116, the driving gear 116 moves and drives the driven gear 118 to move, and when the driven gear 118 moves, the driven gear 118 can synchronously drive the first driving shaft 122 to rotate, so that the purpose of driving the first driving shaft 122 to rotate in the forward direction or the reverse direction can be achieved along with the forward and reverse rotation of the motor.

When the first driving shaft 122 encounters a foreign object to be stuck in the forward or reverse rotation process, the driving teeth 116 and the driven teeth 118 are subjected to resistance in transmission connection, and at this time, although the springs can still push the driven teeth 118 against the driving teeth 116, the resistance is much larger than the elastic supporting force of the springs, so that the rotational connection between the driving teeth 116 and the driven teeth 118 is not stable any more. That is, the driving shaft does not follow the driven gear 118 synchronously, the motor only drives the driving gear 116 to idle, and the first driving shaft 122 does not rotate any more.

When the foreign matter is removed, the driven teeth 118 again achieve the engagement transmission with the driving teeth 116 under the elastic supporting force of the elastic members 120, and at this time, the first driving shaft 122 can continue to achieve the power transmission with the motor.

When power is off, the motor stops, and if the cover plate assembly 108 is in a reset state, a user can directly press the cover plate assembly 108, so that the cover plate assembly 108 is in a pressing state from the reset state, and because the pressure applied to the cover plate assembly 108 by the user is far greater than the force of the meshing between the driving teeth 116 and the driven teeth 118, the user can still buckle the exposed handle slot 102 to open the door body 100.

In the embodiment of the present invention, the elasticity of the clutch mechanism 110 also has another effect in that a certain gap exists between the output shaft of the motor and the driving tooth 116 due to the dimensional accuracy or assembly of the components, when the motor starts to rotate, the cover assembly 108 cannot be moved by the motor in a short time due to the certain gap existing between the output shaft of the motor and the driving tooth 116, as shown in fig. 12, the cover assembly 108 moves a certain distance in a direction approaching the inner side of the door body 100 under the action of gravity, and the cover assembly 108 does not continue to move under the drive of the motor until the motor is engaged with the driving tooth 116. The movement of the cover plate assembly 108 under gravity does not match the speed of the motor drive, resulting in a non-smooth movement. After the clutch mechanism 110 is added, the friction torque generated when the first driving shaft 122 drives the driving teeth 116 and the driven teeth 118 to rotate is greater than or equal to the torque generated by the gravity borne by the cover plate assembly 108, after the motor starts to rotate, the cover plate assembly 108 is kept stationary under the friction torque until the motor is meshed with the driving teeth 116, and the cover plate assembly 108 starts to move under the driving of the motor, so that the movement speed of the cover plate assembly 108 is ensured to be more stable, and the whole movement process is smoother.

In a second aspect, an embodiment of the present invention provides a refrigerator, which includes a cabinet and the door assembly for a refrigerator described above, wherein the door assembly for a refrigerator is pivotally mounted to the cabinet.

According to the refrigerator in the second aspect of the invention, by arranging the door assembly for the refrigerator, on the premise that the door body 100 is convenient to open and close, the surface of the door body 100 can be ensured to be smooth and concise when the door body 100 is in a closed state. While also avoiding pinching the user and damage to the drive device 104.

In embodiments of the present invention, the refrigerator may be a refrigerator, a freezer, a wine chest, or the like.
