The refrigerator includes a case 200, a storage space having an opening provided in the case 200, a door 300 covering the opening, and a handle assembly 100 connected to the door 300, as shown in fig. 1. The door 300 is connected with the case 200 through a hinge, and the handle assembly 100 is disposed at the other side away from the hinge.

The box 200 includes enclosing the open-ended cabinet mouth 210, and the door body 300 is used for closing the opening, and the door body 300 includes the sealing member 310 that offsets with cabinet mouth 210, and sealing member 310 can be set up to the sealing ring of bar, and sealing member 310 connects on the door body 300, and when the door body 300 was closed, sealing member 310 was laminated on cabinet mouth 210 around the opening round to isolate storage space and external world, play sealed effect. The outside is the outside atmosphere space, and atmospheric pressure is normal atmospheric pressure, is used for refrigerating in the storage space, generally is less than external temperature in the storage space, if in the state of totally enclosed, the atmospheric pressure in the storage space will be less than external atmospheric pressure.

To clearly express the position and direction described in the present embodiment, the handle assembly 100 is defined to be located in front of the door body 300, the hinge is located at the rear of the case 200, the direction of the door body 300 with respect to the case 200 is defined as up, the reverse direction is defined as down, and both sides facing the handle assembly 100 from the front are defined as left and right, respectively. The left and right sides of the present embodiment may be interchanged, and the following "right lever 26", "left lever 22", and "driving member 23" are at least partially disposed in the left door body connecting portion 10, and the abutting member 25 is at least partially disposed in the right door body connecting portion 10 "may be interchanged, and the right and left sides may be interchanged without absolute limitation to the right and left directions.

As shown in fig. 1, the door 300 is disposed above the case 200, and as shown in fig. 2a, the opening 210 of the refrigerator according to the present embodiment includes a front wall 2102 and an upper wall 2101, the front wall 2102 faces forward, the upper wall 2101 faces upward, and the sealing member 310 abuts against the upper wall 2101 from top to bottom.

Lifting portion 220

As shown in fig. 2, the case 200 of the present embodiment further includes a lifting portion 220 connected to the cabinet opening 210, the lifting portion 220 includes a lifting member 221, and the lifting member 221 is used to lift the sealing member 310 upward, so that a gap is formed between the sealing member 310 and the cabinet opening 210, and after entering the external atmosphere, the air pressure in the refrigerator is equal to the external air pressure.

The chest 210 may also include an upper recess 2120 recessed downwardly from the upper wall 2101, the upper recess 2120 housing the lifter 221.

Further, the upper recess 2120 includes a flat bottom wall 2121 near the opening side and an inclined bottom wall 2122 away from the opening, and the lifting portion 220 further includes a rotation shaft 222 provided between the inclined bottom wall 2122 and the flat bottom wall 2121, and the lifting member 221 is rotatably connected to the rotation shaft 222.

The inclined bottom wall 2122 may be inclined forwardly and downwardly, and the planar bottom wall 2121 may be parallel to the upper wall 2101 and parallel to the horizontal plane. The mass of the lifting member 221 before the rotation axis 222 is smaller than the mass of the lifting member 221 after the rotation axis 222, so that the rotation axis 222 falls on the planar bottom wall 2121 instead of the inclined bottom wall 2122 without external force. The coupling lifter 221 is generally a homogeneous object, so the rotational axis 222 of the lifter 221 is located at a shorter distance from the front end than the rear end.

A socket 2123 is further provided in the upper recess 2120, and as shown in fig. 2a, the rotation shaft 222 is inserted into the socket 2123, and when one end of the rising portion 220 is rotated upward about the rotation shaft 222, the other end is rotated downward about the rotation shaft 222.

When the door 300 is closed and no external force is applied, as shown in fig. 3b, the lower surface of the lifting member 221 abuts against the planar bottom wall 2121, and the upper surface of the lifting member 221 is flush with the upper wall 2101, so that the sealing member 310 seals with either the upper wall 2101 or the lifting member 221, and no problems of air leakage or cold leakage occur.

When an external force is applied to the lifting member 221, the lower surface of the lifting member 221 abuts against the inclined bottom wall 2122, and at least part of the upper surface of the lifting member 221 is higher than the upper wall 2101 as shown in fig. 4 b. The portion of the lifting member 221 above the upper wall 2101 will lift the portion of the sealing member 310 against the lifting member 221, thus creating a gap in the side of the lifting member 221 for air communication between the outside and the inside.

After the door 300 is opened, the lower surface of the lifter 221 abuts against the planar bottom wall 2121. Thus, when the door is opened, a notch is not formed on the upper surface of the cabinet opening 210 to fall into dust and food.

Bearing part

The case 200 of the present embodiment further includes a receiving portion including a receiving surface 2131; the cabinet 210 includes a right protrusion 2130 protruding from the front wall 2102 toward the front, and the receiving surface 2131 is provided on the upper surface of the right protrusion 2130 in the present embodiment, as shown in fig. 1, 2a, 3d, and 4 d.

Handle assembly 100

The handle assembly 100 of the present embodiment includes a door body coupling portion 10, a pressing portion 20, and a handle portion 30.

The door body connecting portions 10 are fixedly connected to the door body 300, two groups of door body connecting portions 10 can be arranged side by side left and right, as shown in fig. 2, the handle portion 30 is connected between the two door body connecting portions 10, the door body connecting portions 10 and the handle portion 30 can be integrally formed, or the handle portion 30 and the door body connecting portions 10 can be formed by buckling an upper cover and a lower cover.

The pressing portion 20 includes a pressing piece 21, a driving piece 23, and a holding piece 25, as shown in fig. 2 a. The pressing piece 21 is movably connected to the door body connecting portion 10, and the pressing piece 21 has a closed state and an open state. A limiting structure may be provided in the door body coupling part 10 or the handle part 30 to limit the movement range of the pressing piece 21, and one of the limiting positions of the movement of the pressing piece 21 is a closed state as shown in fig. 3a and the other limiting position of the movement is an open state as shown in fig. 4 a. The movement direction from the closed state to the open state may be upward movement, in accordance with the direction of opening the door. Taking fig. 3a and fig. 4a as an example, the closed state is the position where the pressing piece 21 falls to the lowest point, and the open state is the position where the pressing piece 21 moves to the highest point, and the lower surface of the pressing piece 21 is flush with the lower surface of the lower cover.

The closing state of the pressing member 21 is also a state in which the sealing member 310 is completely sealed, and when the pressing member 21 is in the opened state, the sealing member 310 may be partially separated from the cabinet opening 210 to generate a gap, or the lifting member 221 may be returned to the closed state by its own weight after the door 300 is completely lifted.

The upper recess 2120 is aligned with the driver 23 and the right projection 2130 is aligned with the abutment 25. The driving member 23 may drive the lifting member 221 such that when the driving member 23 moves in the direction of the lifting member 221, the driving member 23 and the lifting member 221 move in the same direction. The abutment 25 can abut against or be remote from the receiving surface 2131.

Seal 310 is aligned with planar bottom wall 2121 and driver 23 is aligned with sloped bottom wall 2122. The rotation shaft 222 is between the sealing member 310 and the driving member 23 as shown in fig. 3b or 4 b.

The driving member 23 is at least partially disposed in the left door body connecting portion 10, the abutting member 25 is at least partially disposed in the right door body connecting portion 10, and the pressing member 21 simultaneously drives the driving member 23 and the abutting member 25 to move. Thus, when the pressing piece 21 is triggered, the driving piece 23 and the supporting piece 25 can be simultaneously pushed to move, and a user can realize one operation and two functions, so that the internal and external air pressure balance can be realized, and the door opening assistance of the box body 200 to the door body 300 can be realized, so that the door body 300 is easier to open.

In the closed state, the lifting member 221 and the surface of the cabinet opening 210 beside the lifting member 221 are abutted against the sealing member 310, and the sealing member 310 is sealed with the upper wall 2101 or the lifting member 221, so that the problems of air leakage and cold leakage are avoided, as shown in fig. 3 b.

In the process of switching the closed state to the open state, the pressing piece 21 simultaneously drives the driving piece 23 to move towards the lifting piece 221 and the abutting piece 25 to move towards the bearing surface 2131, the driving piece 23 drives the lifting piece 221 to move until the surface of the cabinet opening 210 beside the lifting piece 221 is separated from the sealing piece 310, the abutting piece 25 abuts against the bearing surface 2131, and the distance between the bearing surface 2131 and the door body connecting part 10 is increased. And in the process the lower surface of the lifter 221 abuts the inclined bottom wall 2122 and at least part of the upper surface of the lifter 221 is higher than the upper wall 2101 as shown in fig. 4 b.

At this time, the driving member 23 moves downward, one end of the lifting member 221 abutting against the driving member 23 also moves downward, and the other end of the lifting member 221 moves upward around the rotation shaft 222. The abutment 25 abuts against the receiving surface 2131, and the receiving surface 2131 applies a reaction force to the abutment 25 opposite to the first direction, that is, urges the door connecting portion 10 to move away from the receiving surface 2131.

In this embodiment, the pressing member 21 may extend from the position of the left door body connecting portion 10 to the position of the right door body connecting portion 10, so that pressing any position between the left and right door body connecting portions 10 can be pressed against the pressing member 21, and movement of the driving member 23 and the abutting member 25 is achieved.

Further, the pressing portion 20 further includes a first elastic member 24, one end of the first elastic member 24 abuts against the door body connecting portion 10, the other end abuts against the driving member 23, and the first elastic member 24 always has a tendency to drive the driving member 23 to move away from the lifting member 221.

The pressing portion 20 further includes a second elastic member 27, one end of the second elastic member 27 abuts against the door body connecting portion 10, and the other end abuts against the abutting member 25, and the second elastic member 27 always has a tendency to urge the abutting member 25 to move in a direction away from the receiving surface 2131. The first elastic member 24 and the second elastic member 27 may each be provided as a spring such that the lifting member 221 is maintained in a horizontal state in fig. 3b after the pressing force is removed, and the abutting member 25 is moved to a position farthest from the receiving surface 2131.

Further, the pressing portion 20 further includes a left lever member 22 and a right lever member 26, one end of the left lever member 22 abuts against the pressing member 21, the other end abuts against the driving member 23, one end of the right lever member 26 abuts against the pressing member 21, the other end abuts against the abutting member 25, and rotation shafts are provided between both ends of the left lever member 22 and the right lever member 26, so that the movement directions of the pressing member 21 and the driving member 23 are opposite, and the movement directions of the pressing member 21 and the abutting member 25 are opposite. In this way, since the door 300 is far away from the case 200 when opening the door, and the supporting member 25 and the driving member 23 need to move toward the case 200, that is, after the left lever member 22 and the right lever member 26 are provided, when opening the door, the moving direction of the pressing member 21 is the same as the moving direction of the door 300, so that two effects can be achieved by facilitating one door opening action, the user does not need to switch the direction of the force, and the operation like lifting the door normally can be performed.

In combination with the door 300 of the present embodiment being disposed above the case 200, the driving member 23 is disposed above the lifting member 221, and the supporting member 25 is disposed above the receiving portion, and the direction of movement of the pressing member 21 is the same as the direction of movement of the door 300 during the switching from the closed state to the open state. This allows the upward force applied to push the lifter 221 up to lift the seal 310 while the door 300 is pulled up, thereby balancing the internal and external pressure differences and pushing down on the receiving surface 2131, so that the receiving surface 2131 applies upward assistance.

The lower cover of the present embodiment is provided with a slot 31, as shown in fig. 3a or 4a, the pressing member 21 includes a holding surface 211 and a pressing handle 212, and the pressing handle 212 extends through the slot 31 to below the slot 31, that is, the pressing member 21 is exposed outside the handle portion 30. The supporting surface 211 is disposed above the slot 31, and the width of the supporting surface 211 is greater than the width of the slot 31, so that the pressing member 21 does not fall out of the slot 31. The pressing member 21 is provided to extend downward under the lower cover, so that the pressing member 21 can be conveniently held to move upward when the door is opened, opposite to the moving direction of the driving member 23.

The main movement mode of the present embodiment is to control the movement of the lifting element 221 by the driving element 23, and when the left lever element 22 and/or the right lever element 26 are not provided, the movement direction of the pressing element 21 may be the same as the movement direction of the driving element 23 and the supporting element 25, and the upward movement of the pressing element 21 directly lifts the position where the lifting element 221 is connected to the sealing element 310. The position of the pressing piece 21 may not be limited to the lower side of the handle portion; the handle can be arranged above the handle, and even the handle is arranged on the side face through a lever structure with other shapes, so that the handle is convenient for a user to operate.

The ends of the left lever member 22 and the right lever member 26 facing the pressing member 21 are provided with arc surfaces, the sides of the abutting surfaces 211 facing the left lever member 22 and the right lever member 26 are provided with arc surfaces, as shown in fig. 2a, 3a and 4a, the ends of the left lever member 22 and the right lever member 26 facing the pressing member 21 do arc motion around the rotating shaft, so that the abutting surfaces 211 in contact with the left lever member 22 and the right lever member 26 are also provided with arc shapes, and the contact between the abutting surfaces 211 and the left lever member 22 and the right lever member 26 is smoother, thereby avoiding stress concentration.

Further, the side of the driving member 23 facing the left lever member 22 and the side of the abutting member 25 facing the right lever member 26 are both provided as flat surfaces, and the left lever member 22 slides on the surface of the driving member 23 during the switching between the closed state to the open state, as shown in fig. 3b to 4 b; the right lever member 26 slides on the surface of the abutment member 25 as shown in fig. 3d to 4 d.

The distance between the driving member 23 and the lifting member 221 is smaller than the distance between the holding member 25 and the receiving surface 2131. In this embodiment, the distance between the driving member 23 and the lifting member 221 may even be 0, i.e. in the closed state, the driving member 23 abuts against the lifting member 221, as shown in fig. 3b to 4 b. In the closed state, the supporting member 25 is spaced from the receiving surface 2131 by a distance as shown in fig. 3d to 4 d. Thus, when the pressing piece 21 is triggered, the driving piece 23 can immediately drive the lifting piece 221 at one end to move downwards, and the lifting piece 221 at the other end of the rotating shaft 222 moves upwards, so that the prying sealing piece 310 at the first time balances the internal and external air pressure; since the abutting piece 25 is spaced from the receiving surface 2131 by a certain distance, the abutting piece 25 can abut against the receiving surface 2131 only after the pressing piece 21 moves by a certain distance, and then the assisting function is achieved. The distance between the abutment 25 and the receiving surface 2131 provides room for the downward movement of the driver 23 and the prying up of the seal 310.

The distance from the contact position of the pressing piece 21 and the right lever member 26 to the rotating shaft is longer than the distance from the contact position of the supporting piece 25 and the right lever member 26 to the rotating shaft, so that the pressing piece 21 moves for a longer length, the supporting piece 25 can only move for a shorter length, and the effect of saving labor when the door is opened is achieved through the lever principle.

The door opening process is described below:

when the door 300 is closed and the pressing piece 21 is not forced, the lifting piece 221 is in a horizontal state, the sealing piece 310 is not lifted, the sealing piece 310 is respectively abutted against the lifting piece 221 and the upper wall 2101 of the cabinet, and at the moment, external air cannot enter the storage space;

when the door is opened, a user holds the handle part, the pressing piece 21 inevitably holds the pressing piece 21 because the pressing piece 21 extends from left to right, and because the pressing piece 21 extends downwards below the lower cover, the user inevitably applies upwards force to the pressing piece 21 when applying upwards force to the handle assembly 100, so that the user does not need to deliberately press the pressing piece 21 in the door opening process, naturally applies upwards force to the pressing piece 21, and then the driving piece 23 and the abutting piece 25 simultaneously move downwards, so that the front end of the lifting piece 221 moves downwards, the rear end of the lifting piece 221 moves upwards, the position where the sealing piece 310 abuts against the lifting piece 221 is lifted, a gap exists between the side sealing piece 310 and the upper wall 2101 at the position, external air enters the refrigerator through the gap to realize internal and external air pressure balance, and meanwhile, the abutting piece 25 abuts against the bearing surface 2131 to form assistance for door opening by the opposite direction, and the door opening is convenient for the user;

after the door 300 is opened, since the lifting member 221 is not pressed by the driving member 23, the lifting member 221 rotates back to the horizontal state of fig. 3b under the action of gravity, and the upper surface of the lifting member 221 is flush with the upper wall 2101, so that a gap is not formed on the upper surface of the cabinet opening 210 to fall into dust and food;

after the user closes the door 300 and releases his hands, the pressing member 21 itself falls down to the lowest point by gravity, and the driving member 23 is restored to the original state by the first elastic member 24, that is, the front end of the lifting member 221 is not pressed downward, the sealing member 310 is restored to the sealing with the cabinet opening 210 and the lifting member 221, and the abutting member 25 is restored to the original state by the second elastic member 27.

Compared with the common technology, the embodiment has the following beneficial effects:

on the one hand, the refrigerating device 1000 can generate a gap between the sealing member 310 and the cabinet opening 210 before the door is opened, so that the external atmosphere enters the inside of the refrigerating device 1000 through the gap, the internal and external air pressures are balanced, and the door is opened more labor-saving; on the other hand, under the action of the abutting force of the abutting piece 25 and the bearing part, upward force is reversely applied to the door body 300, the door opening assisting effect is achieved, the door body 300 can be smoothly opened, and the use experience of a user is improved.
