[00271 As shown in FIG. 1 through FIG. 3, a refrigerator 100 includes a door body 101 and a cabinet 102. The door body 101 is pivoted to a lateral edge of the cabinet 102 and may pivot relative to the cabinet 102 to close the cabinet 102, or the door body may open relative to the cabinet 102. The cabinet 102 includes a plurality of compartments for storing items.
[00281 A front side of the door body 101 is provided with an assist handle. The assist handle includes a handle bar, a rotation shaft 20, a guide groove 90, a push rod 50, and a resistance structure 60. The handle bar is pivoted to the rotation shaft 20, the guide groove 90 run through the door body 101, the push rod 50 is slidably disposed in the guide groove 90, and the resistance structure 60 is located on one side of the push rod 50; when the handle bar pivots about the rotation shaft 20 and pushes against a proximal end of the push rod 50 to make the push rod 50 to slide in the guide groove 90, a distal end of the push rod 50 pushes against the cabinet 102 to open the door body 101. The resistance structure 60 includes a first tooth-like structure 61 and a second tooth-like structure 62 that mesh with each other. The first tooth-like structure 61 engages one side of the push rod 50 and may move along with the push rod 50, so that the first tooth-like structure 61 moves relative to the second tooth-like structure 62 to form a certain rotation resistance which is used to improve the comfort of the user pulling the handle bar to open the door and reduce the noise caused by the return ofthe handle bar.
[0029] In the present invention, a side of the door body 101 close to the user is defined as "a front side", and the other side away from the user is defined as "a rear side"; an end of the push rod 50 close to the user is defined as a proximal end, and the end far away from the user is defined as a distal end.
[00301 As shown in FIG. 1 and FIG. 2, the handle bar is disposed on the front side of the door body 101 and pivoted to the rotation shaft 20 so that the handle bar can pivot about the rotation shaft 20. The handle bar includes an integrally formed handle portion 10 and a lever portion 11. The handle portion 10 and the lever portion 11 are respectively located on both sides of the rotation shaft 20. In other words, a rotation shaft hole (not shown) provided on the handle bar divides the handle bar into the handle portion 10 and the lever portion 11, and the rotation engages in the rotation shaft hole, wherein a length of the handle portion 10 is greater than the length of the lever portion 11. When the user pulls the handle portion 10 to turn the handle bar, the handle portion 10 has a larger moment arm, thereby ensuring that the user may turn the handle bar with a smaller force, and achieving a force-saving effect. A protrusion 12 is disposed at a top of the level portion 11 and abuts against the front end of the push rod 50.
[00311 In the present embodiment, the rotation shaft 20 is for example fixed in a base 30 on the front side of the door body 101. The base 30 is a box with an end open. The opening of the box engages on the surface of the front side of the door body 101, and is not limited thereto. In other embodiments of the present invention, the rotation shaft is arranged at a connection between the handle portion and the lever portion on the handle bar, a rotation shaft hole corresponding to the rotation shaft on the handle bar is arranged in the base, and the rotation shaft on the handle bar is inserted into the rotation shaft hole so that the handle bar pivots around the rotation shaft.
[0032] The base 30 encapsulates the lever portion 11 of the assist handle, the rotation shaft 20, a portion of the push rod 50 and an elastic member 40 therein, so that the refrigerator 100 has a good appearance.
[00331 As shown in FIG. 2, the push rod 50 includes a first rod body 51 and a second rod body 52. The first rod body 51 and the second rod body 52 are connected by the elastic member 40. The elastic member 40 is for example a spring. An end of the spring is sleeved around a post on the first rod body 51, the other end of the spring is sleeved around another post on the rod body 52, and post on the first rod body 51 is opposite to the another post on the second rod body 52. In other embodiments of the present invention, the elastic member may also be a metal elastic sheet, the metal elastic sheet is arranged between the first rod body and the second rod body, both ends of the metal elastic sheet are respectively welded or adhered on a surface of the first rod body and another surface of the second rod body, and the surface is opposite to the another surface.
[0034] The elastic member 40 provides an elastic force for returning the handle bar. Specifically, the user applies a force to pull the handle portion 10, so that the handle portion 10 and the lever portion 11 rotate counterclockwise about the rotation shaft 20, and the protrusion 12 of the lever portion 11 pushes against the front end of the first rod body 51, the first rod body 51 compresses the elastic member 40, the elastic member 40 acts on the front end of the second rod body 52 so that the second rod body 52 moves in the guide groove 90, and the distal end of the second rod body 52 extends out of the opening at the distal end of the guide groove 90 and pushes against the cabinet 102 to open the door body 101 relative to the cabinet 102. In the process of opening the door body 101, the elastic member 40 is compressed to be in a compressed state. After the door body 101 is opened, the distal end of the second rod body 52 abuts against the cabinet 102, and the user no longer applies a force to the handle portion 10, and then the force applied to the elastic member 40 is removed. At this time, the elastic member 40 in the compressed state returns to an extended state to generate an elastic force, the elastic force acts on the first rod body 51, the first rod body 51 pushes the protrusion 12 of the level portion 11 to move towards the user, the lever portion 11 rotates clockwise about the rotation shaft 20, and the handle portion 10 rotates clockwise together and then returns back.
[00351 In addition, the door body 101 is closed on the cabinet 102, the cabinet 102 pushes against the distal end of the second rod body 52, and the second rod body 52 compresses the elastic member 40 so that the portion of the second rod body 52 extending out of the guide groove 90 retracts back into the interior of the guide groove 90.
[00361 In the present embodiment, the first rod body 51 and the elastic member 40 are located on the front side of the door body 101, and the second rod body 52 is located in the guide groove 90, but the arrangement is not limited to this. In other embodiments of the present invention, the first rod body, the elastic member and the second rod body may be simultaneously disposed in the guide groove.
[00371 Further referring to FIG. 1 and FIG. 2, in order to improve the comfort of the assist handle, the assist handle further includes a resistance structure 60 which is disposed on one side of the push rod 50 to provide resistance. The resistance structure 60 includes a first tooth-like structure 61 and a second tooth-like structure 62 meshing with each other. The first tooth-like structure 61 is disposed on one side of the first rod body 51 and fixedly connected to the first rod body 51, and may move along with the first rod body 51; the second tooth-like structure 62 is located below the first tooth-like structure 61. In the present embodiment, the first tooth-like structure 61 is for example a rack, the second tooth-like structure 62 is for example a gear, and the gear meshes with a distal end of the rack. When the first rod body 51 moves towards the rear side of the door body 101, the rack moves towards the rear side of the door body along with the first rod body 51, and the gear rotates counterclockwise to mesh with a proximal end of the rack; when the first rod body 51, driven by the elastic piece 40, moves toward the front side of the door body 101, the rack moves towards the front side of the door body 101 along with the first rod body 51, and the gear rotates clockwise to gradually mesh with the distal end of the rack.
[00381 The rotation of the lever portion 11 and the elastic force provided by the elastic piece 40 enable the first rod body 51 to move reciprocally, and then the rack moves reciprocally along with the first rod body 51. Hence, during the reciprocal movement of the rack, the gear moves clockwise or counterclockwise on the surface of the rack, and the rotation of the gear provides an appropriate rotation resistance. On the one hand, while the handle portion 10 is pulled to open the door body 101, the rotation resistance reduces a movement rate of the first rod body 51 of the push rod 50 so that the second rod body 52 moves slowly along the guide groove 90 to gradually push against the cabinet 102, and the door body 101 gradually opens to improve the user's door-opening comfort; on the other hand, after the door body 101 is opened, the first lever body 51 moves toward the front side of the door body 101 under the action of the elastic member 40, the rotation resistance may slow down the movement rate of the first lever body 51 so that the lever portion 11 slowly pivots to return, and the handle portion 10 does not impinge on the front side of the door body 101, thereby reducing the noise caused by the return of the handle bar.
[00391 In the present embodiment, the first tooth-like structure 61 and the second tooth-like structure 62 are disposed on the front side of the door body 101, and the first tooth-like structure 61 engages on the first rod body 51 and moves along with the first rod body 51, but the arrangement is not limited to this. In other embodiments of the present invention, the first tooth-like structure and the second tooth-like structure may be disposed in the interior of the door body, and the first tooth-like structure engages on the second rod body.
[0040] Further referring to FIG. 1 and FIG. 2, in order to avoid the problems such as cold leakage and frosting caused by the guide groove 90 on the door body 101, the guide groove 90 is provided with a guide sleeve 70 and a pair of bellows 80, wherein the guide sleeve 70 is received in the guide groove 90, and the second rod body 52 runs through the guide sleeve 70; the pair of bellows 80 are located at the openings at both ends of the guide groove 90, outer sides of the pair of bellows 80 are respectively connected to inner walls at both ends of the guide sleeve 70, and inner sides of the pair of bellows 80 are respectively sleeved on the outer surface of the proximal end and the outer surface of the distal end of the second rod body 52. That is, the pair of bellows 80 may be regarded as being filled between the ends of the second rod body 52 and the ends of the guide sleeve 70 respectively so that the space between the pair of bellows 80 is a sealed space, and the sealed space may function for heat preservation and heat insulation.
[0041] In addition, the bellows 80 near the rear side of the door body 101 is filled between the distal end of the guide sleeve 70 and the distal end of the second rod body 52, and may block the overflow of the cold air through the guide groove 90 of the door body 101 when the door body 101 closes the cabinet 102, thereby avoiding the frosting at the assist handle of the door body.
[0042] In addition, the door body 101 includes a first housing, a thermal insulation layer and a second housing. The thermal insulation layer is disposed between the first housing and the second housing.
