The door seal 40 has certain magnetism and can be attracted with the door frame.

In order to clearly express the position and direction described in the present embodiment, a first direction is defined as a forward direction, and a direction opposite to the first direction is defined as a rear direction, that is, the drawer may be pulled out of the case forward, and on a surface perpendicular to the first direction, upper, lower, left and right may be defined respectively, and here, a direction defined by referring to gravity is an upward direction, and upper, lower, front and rear sides of the refrigerator are left and right sides, respectively.

The door body 100 further comprises a power assisting mechanism 10, the power assisting mechanism 10 is shown in fig. 4-11, the power assisting mechanism 10 comprises a seat body 16, a lever 14, an ejection assembly 15 and a handle assembly 120, the seat body 16 is arranged in the door cavity, the seat body 16 is connected with the trim assembly 20, the seat body 16 encloses a cabin 160, and the seat body 16 comprises a limiting part; the seat 16 is used for accommodating other materials in the booster mechanism 10, and the region except the cabin 160 in the door cavity is provided with a heat-insulating member, which can be a foaming material, so that the material in the seat 16 can be prevented from being influenced when the region except the seat 16 is foamed by the foaming material.

The lever member 14 includes a rotating shaft rotatably connected to the base 16, a proximal end 142 disposed at one end of the rotating shaft, and a distal end 141 disposed at the other end of the rotating shaft, wherein a distance from the proximal end 142 to the rotating shaft is smaller than a distance from the distal end 141 to the rotating shaft, and the proximal end 142 and the distal end 141 move in opposite directions; the lever member 14 may utilize leverage, and since the moment arm length of the distal end 141 is longer than the moment arm length of the proximal end 142, the force applied at the distal end 141 may be less than the force applied at the proximal end 142.

The ejector assembly 15 is connected to the proximal end 142; the handle assembly 120 is movably connected to the base 16, the handle assembly 120 includes a slot 123, the extending direction of the slot 123 is the same as the extending direction of the handle slot 211, the handle assembly 120 is connected to the distal end 141, and the limiting portion limits the movement of the handle assembly 120 along the first direction. The ejector assembly 15 is partially located within the cabin 160, and the ejector assembly 15 may partially extend out of the cabin 160 when the ejector assembly 15 is desired to be against a door frame.

The handle assembly 120 includes a pulling wall 121 and a front shielding part 122, the pulling wall 121 and the door body enclose a slot 123 for grasping the drawer, the front shielding part 122 is connected to the front of the pulling wall 121, the handle assembly 120 is connected to the distal end 141, the handle assembly 120 is movable in the front-rear direction, the pulling wall 121 has a pulled-out state at the forefront end and a reset state at the rearmost end, in which the front shielding part 122 covers a space between the front shielding part 122 and the door panel 30 above, and in which the front shielding part 122 is moved to the front of the door panel 30. The user can stretch into the cell body 123 with the hand, pulls handle subassembly 120 forward motion, and not receive the structure restriction of current door, only can scratch the inslot with the finger and dial forward, so this embodiment makes things convenient for the user to exert oneself more, and this embodiment has very big difference with current mode of gripping, current application of force mode.

The contour of the grooves of the molding assembly 20 at both sides of the handle assembly 120 is identical to the shape of the groove body 123, the appearance is beautiful, and the user can conveniently pull the drawer from any position.

When the handle assembly 120 drives the distal end 141 in a first direction, the distal end 141 drives the ejector assembly 15 relatively away from the housing 16, that is, when the handle assembly 120 moves forward, the ejector assembly 15 moves rearward relative to the housing 16. In addition, when the door is opened, if the ejection assembly 15 is always abutted against the door frame, the ejection assembly 15 may not move in the space, and the seat 16 moves forward relative to the ejection assembly 15.

During at least a portion of the relative distance between the ejection assembly 15 and the housing 16, the ejection assembly 15 abuts against the door frame. If there is a possible idle stroke in the stroke, the stroke of opening the door is divided into three stages, (1) in the door closing state, the ejection assembly 15 is not propped against the door frame, and the ejection assembly 15 moves backwards at first, and the seat 16 is not moved; (2) When the ejection assembly 15 is pushed against the door frame, the ejection assembly 15 is not moved, and the seat 16 moves forwards; (3) When the ejector assembly 15 is moved forward until the door frame is separated, the ejector assembly 15 moves forward together with the seat 16. If there is no idle stroke in the stroke, the following movement is started from the first state.

Because of the labor-saving principle of the lever, the ejection force of the ejection assembly 15 of the power-assisted mechanism 10 against the door frame is far greater than the force of the user acting on the handle assembly 120, and meanwhile, the area of the contact surface of the ejection assembly 15 with the door frame is greater than the contact surface of the door body 100 with the door frame (the contact surface of the whole door seal 40 with the door frame in practice), so that a gap is opened at the position at first due to the smaller area, the outside air can enter the refrigerator, the pressure difference between the refrigerator and the outside is balanced, the negative pressure is reduced or even eliminated, the required door opening force can be greatly reduced, and the user door opening body 100 is improved.

Further, as shown in fig. 6, the booster mechanism 10 is connected to the middle position of the molding assembly 20. In this way, the torsion moment is avoided being generated in the left-right direction, the stress of the door is more uniform and stable from the middle to the two sides, and the deformation of the door body 100 is avoided in long-term use.

Further, as shown in fig. 4, 5 and 7, the connection structure between the shaft to the distal end 141 is curved in a direction away from the first direction with respect to the extension line of the connection line of the proximal end 142 to the shaft. Because of the limited space within the door 100 and the lesser distance that the proximal end 142 moves, the distal end 141 needs to move a longer distance, i.e., the ejector assembly 15 moves a lesser distance rearward and the handle assembly 120 needs to move a longer distance forward. Bending the section from the distal end 141 to the shaft rearward allows the pulling portion 131 to be initially located further rearward, thereby providing more room for forward movement. In addition, it is desirable to avoid the distal end 141 being exposed from the channel 123 when the handle assembly 120 is moved to the forwardmost position, so that a better use experience may be obtained by bending the segment back.

Further, the molding assembly 20 includes a molding body 21 and a spacer 22, the spacer 22 is fixedly connected to the molding body 21, and the handle assembly 120 is separated from the molding body 21 by the spacer 22. The molding body 21 includes the above-mentioned handle groove 211, as shown in fig. 4, the handle 12 includes the first contact surface 1220, the spacer 22 includes the second contact surface 221, the handle 12 is not in contact with the molding component 20, the handle 12 may be made of metal, the molding component 20 may be made of plastic, if the metal is in contact with the plastic, on one hand, the friction coefficient may be larger, and on the other hand, the metal may damage the plastic, so that the spacer 22 is added to the molding body 21, the spacer 22 is made of the same material as the handle component 120, and the first contact surface 1220 and the second contact surface 221 are relatively smooth.

The spacer 22 may include a clamping portion 222 and a screw portion 223, which are fixedly connected with the molding body 21 through clamping and screw connection, respectively. In addition, the seat 16 may be fixedly connected to the molding body 21 by a fastening and/or screwing manner.

As shown in fig. 4 and 7, the handle assembly 120 includes a handle member 12 and a connector 13, the handle member 12 being fixedly connected to the connector 13, the connector 13 including a pulling portion 131, the pulling portion 131 driving the distal end 141 to move during at least a portion of the movement of the handle assembly 120; the handle member 12 and the connecting member 13 may be fixed by bolts.

The handle assembly 120 includes a guide portion, as shown in fig. 7, provided in a groove shape, for example, a columnar groove extending in the front-rear direction, and also provided in a columnar shape to move inside the stopper portion.

The pulling portion 131 includes a first arc portion, and the distal end 141 includes a second arc portion, and the pulling portion 131 contacts the second arc portion of the distal end 141 through the first arc portion. Local position stress concentration is avoided through the contact of circular arcs, and abrasion is generated.

Further, the ejector assembly 15 includes an ejector 151 and an abutment 152, the abutment 152 is used for abutting against the door frame, the ejector 151 is connected with the proximal end 142, the ejector 151 is fixedly connected to the abutment 152, and the abutment 152 is made of a flexible material.

The supporting piece 152 can be provided with rubber, so that the problem that the door frame is damaged due to the fact that the supporting piece 152 is in contact with the door frame and the contact area is small due to the large strength is avoided.

Further, the booster mechanism 10 further includes a first shaft 18, as shown in fig. 7, the first shaft 18 passes through a through hole 1421 of the proximal end 142 and a through hole 1511 of the ejector 151, and the ejector 151 is rotatably connected to the proximal end 142 through the first shaft 18;

the through hole 1421 of the proximal end 142 and/or the through hole 1511 of the ejector 151 are provided as arc-shaped through holes; the arc through hole and the first shaft 18 are connected, so that displacement and force which are not in the same plane can be transmitted in proportion through the lever, and the transmission blocking phenomenon is reduced while the transmission reliability is ensured.

The booster mechanism 10 of the present utility model discloses two embodiments, a first embodiment is shown in fig. 4 to 8, and a first embodiment is shown in fig. 9 to 11, which are different in that in the first embodiment, the through hole 1511 of the ejector 151 is provided as an arc-shaped through hole, and in the second embodiment, the through hole 1421 of the proximal end 142 is provided as an arc-shaped through hole. If the ejector 151 is made of a metal material, such as an aluminum alloy, it is difficult to manufacture an arc-shaped through hole, and in this case, the second embodiment is used to provide an arc-shaped through hole at the proximal end 142. If the ejector 151 is made of a plastic material, such as injection molding, it is less difficult to manufacture an arcuate through hole, and in this case, the first embodiment is used to provide an arcuate through hole at the proximal end 142.

The booster mechanism 10 further includes a second shaft 19, as shown in fig. 7, the shaft is provided in a hole shape, the second shaft 19 passes through the shaft and the seat 16, and the lever member 14 is rotatably connected to the seat 16 through the second shaft 19.

Further, when the door seal 40 is not in contact with the door frame, the distance from the side of the door seal 40 away from the door panel 30 to the door panel 30 is greater than the distance from the side of the ejection assembly 15 away from the door panel 30 to the door panel 30, as shown in fig. 4, so that when the door body 100 is closed, the ejection assembly 15 is prevented from contacting the door frame first when the door seal 40 is not in contact with the door frame, thereby affecting the sealing of the door seal 40 to the door frame.

The front shielding portion 122 is provided above the door panel 30, and in the pulled-out state, the front shielding portion 122 moves from the rear of the door panel 30 to the front of the door panel 30 above the door panel 30. This does not limit the movement of the handle assembly 120 to the inside of the drawer door entirely, but can also be pulled out of the drawer, thereby increasing the range of motion. And considering that the range of motion of the distal end 141 needs to be greater than the range of motion of the proximal end 142, a greater range of motion of the handle assembly 120 is achieved by allowing the handle assembly 120 to move forward of the door panel 30.

In the reset state, the front end of the front shielding part 122 is substantially flush with the front surface of the door panel 30, as shown in fig. 4, and such drawer is more beautiful in appearance, and looks consistent with the existing refrigerator drawer.

The seat 16 is provided with a first guiding portion, and the handle assembly 120 includes a second guiding portion connected to the pulling wall 121, where the first guiding portion is cooperatively connected with the second guiding portion, so as to guide the pulling wall 121 to move only in the front-rear direction.

As shown in fig. 4 to 11, the first guide portion is provided as a guide groove 161, the second guide portion is provided as a guide block 125, the guide block 125 is provided in the guide groove 161, the elastic member 17 is provided as a compression spring, the cover plate 11 includes a limit projection 111, and both the limit projection 111 and the compression spring are provided in the guide groove 161.

The cover 11 or the limiting portion abuts against the elastic member 17, and the elastic member 17 is used for driving the handle assembly 120 to move in a direction opposite to the first direction. In this embodiment, the cover 11 is provided with a limiting protrusion 111, the guide portion is also provided with a protrusion, the elastic member 17 is provided as a spring, the spring is compressed between the limiting protrusion 111 and the protrusion, the spring is in a state of being always compressed, and the spring drives the handle assembly 120 to move backwards.
