Of course, the door can be opened from the left side or from the right side, so the left-right direction can be reversed.
The door body assembly 10 of the present embodiment, as shown in fig. 1 to 9, includes a door body 11, an adsorption portion 12 and a pressing device, wherein the door body 11 is movably connected to the box 20, the door body 11 includes a door lining supporting surface 1221, and in a door closing state, the door lining supporting surface 1221 supports against the box 20, and the door lining supporting surface 1221 is a surface of the door body assembly 10 closest to the box 20, and more specifically, when the door is closed, the door lining supporting surface 1221 of the door body supports against the frame opening 21 of the box 20.
The adsorption portion 12 is connected to the door body 11, and the adsorption portion 12 includes an adsorption unit 121 facing the door liner supporting surface 1221, and the adsorption unit 121 can be adsorbed to the case 20 by the air pressure. The adsorption part 12 is provided with a plurality of independent adsorption units 121, and when the adsorption units 121 are adsorbed to the box 20 under the action of atmospheric pressure, the door assembly 10 is adsorbed to the box 20.
The pressing device comprises a pressing part 14 and a driving part 13, the pressing part 14 is movably connected with the door body 11, the pressing part 14 is provided with a release position far away from the door liner supporting surface 1221 and a pressing position close to the door liner supporting surface 1221, the pressing part 14 is far away from the adsorption unit 121 in the release position, and the pressing part 14 drives the adsorption unit 121 to move towards the door liner supporting surface 1221 in the pressing position; the driving portion 13 drives the pressing portion 14 to move from the release position to the pressing position. The pressing device is used for driving the adsorption unit 121 to move towards the door liner supporting surface 1221, and the driving mode of the driving part 13 may include: manual control, electric control, pneumatic control, etc. so that the pressing portion 14 can move toward the adsorbing units 121, the adsorbing units 121 are provided in a plurality, the pressing portion 14 is also provided in a corresponding number, and each adsorbing unit 121 is driven to adsorb the case 20.
When the door is closed, the pressing part 14 is controlled by the driving part 13 to drive the adsorption unit 121 to be close to the door liner supporting surface 1221, and the adsorption unit 121 is firmly adsorbed on the box 20 under the action of atmospheric pressure, at this time, even if the driving part 13 does not drive the pressing part 14 any more, or the pressing part 14 is far away from the pressing part 12, the pressing part 12 is adsorbed on the box 20 under the action of atmospheric pressure, and further, the door assembly 10 is always tightly connected with the box 20 under the door closing state.
The butt joint position of the box 20 and the door liner supporting surface 1221, or the frame opening 21, can be set to be a smooth plane, or a layer of sealing silica gel is set, and the adsorption part 12 also comprises a layer of sealing silica gel, so that when the door liner supporting surface 1221 and the frame opening 21 are propped against each other, a certain amount of gas is removed between the door liner supporting surface 1221 and the frame opening 21, and then the door liner supporting surface 1221 and the frame opening 21 are tightly connected together, thereby achieving a good sealing effect.
The adsorption unit 121 of the present invention is not entirely attached to the frame opening 21 of the case 20, and in a closed state, an adsorption cavity 120 isolated from the outside is formed between the case 20 and the adsorption unit 121, and the adsorption cavity 120 corresponds to a small air bag, and air is stored therein, as shown in fig. 3 to 4. When the door is closed, the amount of gas in the adsorption cavity 120 is reduced relative to the door opening state, so that the door assembly 10 is adsorbed on the case 20, and only the amount of gas in the adsorption cavity 120 is reduced, and all the gas does not need to be exhausted. When the door needs to be opened again, the driving part 13 continues to drive the pressing part 14 to move towards the door lining supporting surface 1221, and at this time, the gas in the adsorption cavity 120 is further pressed to be discharged outwards, and the discharging path is necessarily discharged outwards through the gap between the adsorption unit 121 and the box 20. The gap does not exist in a natural state, but the adsorption unit 121 is further pressed, and the air pressure in the adsorption cavity 120 is greater than the external atmospheric pressure, so that the adsorption unit 121 is driven to separate from the case 20. Meanwhile, at this time, because a gap is formed between the adsorption unit 121 and the case 20, and the adsorption unit 121 and the case 20 are separated, the door assembly 10 is pulled in a direction away from the case 20, and the door assembly 10 is separated from the case 20, so that the door assembly 10 is opened.
In summary, when the door needs to be closed, the driving part 13 drives the pressing part 14 to move the adsorption unit 121 towards the door liner supporting surface 1221, and after the door is closed, the force of the driving part 13 is removed, so that the door assembly 10 and the box 20 are adsorbed together.
When the door needs to be opened, the driving part 13 is still controlled to drive the pressing part 14 to move the adsorption unit 121 towards the door lining supporting surface 1221, and at the same time, the door body assembly 10 is pulled to move towards a direction away from the box body 20, so that the adsorption force of the adsorption unit 121 can be relieved, and the door body is easy to open. That is, on the one hand, the door body assembly 10 is not easy to automatically open the door, and the adsorption force is high; on the other hand, the door is convenient to open, and the door is not difficult to open after the adsorption force is large, so that good effects can be obtained when the door is closed and opened.

Further, the driving part 13 includes a holding part 131, as shown in fig. 1 to 3 and 5, the holding part 131 is movably connected to the door body 11, the holding part 131 has a first position and a second position, and when the holding part 131 moves from the first position to the second position, the pressing part 14 moves from the release position to the pressing position. The grip 131 functions to control the movement of the pressing portion 14, that is, the driving force by the user's hand, by controlling the movement of the grip 131. The driving force acts on the position of the grip 131, and the grip 131 may be the position of the handle of the refrigerator 100, and the user operates the grip 131 to move forward and backward when holding it. When the user grips, the grip portion 131 moves to the second position, and when the user relaxes, the grip portion 131 can be restored to the first position, which may be an elastic member that restores the deformation of the grip portion 131 itself, or a reset member that drives the grip portion 131 to move may be provided in the door body 11, and when the user grips, the pressing portion 14 moves from the release position to the pressing position.

The direction in which the pressing portion 14 presses the suction portion 12 is not consistent with or even completely opposite to the direction of the force applied by the user, in this embodiment, the force applied to the grip portion 131 is converted into a motion on a plane parallel to the door liner supporting surface 1221, and then the force on the plane is converted into a motion of the pressing portion 14 toward the suction portion 12.

When the user controls the grip 131 to move forward, the first wedge 136 drives the second wedge 137 to move, the second wedge surface moves on a plane perpendicular to the moving direction of the first wedge 136, the second wedge 137 drives the third wedge 138 positioned on the first slider 132 to move, the second wedge 137 and the third wedge 138 are disposed in a direction opposite to 180 degrees, and the third wedge 138 drives the fourth wedge 139 to move, so that the moving direction of the fourth wedge 139 is opposite to the moving direction of the first wedge 136, more specifically, the moving direction of the pressing part 14 is opposite to the moving direction of the grip 131, and when the distance that the user grips the grip 131 to move forward is greater, the displacement amount that the pressing part 14 presses the suction unit 121 backward is greater.
Further, the driving part 13 further includes a second sliding member 134 and a second pressing member 135, the second pressing member 135 is connected to at least part of the pressing part 14, the first sliding member 132 and the second sliding member 134 are symmetrically disposed on two sides of the holding part 131, as shown in fig. 5, the movement direction of the second pressing member 135 is the same as that of the first pressing member 133, and the movement direction of the second sliding member 134 is opposite to that of the first sliding member 132; the arrangement can make the upper and lower both sides atress of gripping portion 131 equal like this, and the feel that the user held is stable, and only the power of fore-and-aft direction does not have torsion, and the leakproofness of the door body is also good in addition, does not have the problem that the deformation volume of one side adsorption unit 121 is big one side little.

When the user removes the driving force, the first elastic restoring portion 1321 and the second elastic restoring portion 1341 are used for restoring, and the first elastic restoring portion 1321 and the second elastic restoring portion 1341 in the drawing are in a compressed state, and when the user drives the first sliding member 132 and the second sliding member 134 to move, only the force of increasing the compression elasticity, the elastic force of the restoring trend of the first elastic restoring portion 1321 and the second elastic restoring portion 1341 further restores the holding portion 131 to the initial position.
Further, the door body assembly 10 further includes a limiting portion, as shown in fig. 3 to 5, the limiting portion includes a limiting space 151 for limiting the movement of the holding portion 131 between the first position and the second position, and a travel limiting baffle 152 for limiting the sliding directions of the first slider 132, the first pressing member 133, the second slider 134, and the second pressing member 135, the limiting space 151 can enable the holding portion 131 to move only in the limited space, so as to avoid excessively driving the movement of the pressing portion 14, the limiting baffle 152 can be disposed at a plurality of positions in the door body assembly 10, and limits the movement positions of different parts, as shown in fig. 3 to 4, the limiting baffle 152 limits the movement displacement amounts of the first slider 132 and the second slider 134 in the up-down direction, and limits the movement displacement amounts of the first pressing member 133 and the second pressing member 135 in the front-rear direction.
The adsorption unit 121 is configured as an elastic adsorption member, the elastic adsorption member is concave toward the door liner supporting surface 1221, and convex toward a direction away from the door liner supporting surface 1221, when the pressing portion 14 drives the elastic adsorption member to move toward the door liner supporting surface 1221, the elastic adsorption member has a tendency to recover deformation, and the adsorption unit 121 may be configured as a hemispherical shape or a bowl-shaped structure having a spherical top having a tendency away from the door liner supporting surface 1221. When the elastic adsorption piece is pressed to deform, the force for restoring the deformation is balanced with the force applied by the atmospheric pressure, and the increased atmospheric pressure can be continuously obtained due to the fact that the force for restoring the deformation is continuous, so that the adsorption force is larger.
