Hereinafter, the operation of the door opening device 30 having the above structure will be described in more detail with reference to drawings.
As illustrated, the door opening device 30 maintains the state illustrated in
In detail, before operating the door opening device 30, a portion of the operating member 31 is positioned within the handle 250. In addition, the lower protrusion 311b of the operating member 31 maintains a state in contact with the guide protrusion 252a of the handle portion 252, and the upper end of the operating member 31 may be in a state of most protruding toward the inside of the handle 250.
At this time, when the user puts his/her hand into the handle 250, the operating member 31 can naturally come into contact with the user's hand. In addition, the upper end of the operating member 31 may maintain the most spaced state from the front surface of the upper cap decoration 25, that is, the front surface of the freezing chamber door 22. In addition, the operating member 31 may maintain a state parallel to the front surface of the freezing chamber door 22 or a state perpendicular to the upper surface of the freezing chamber door 22.
The supporter 32 maintains a state of being in contact with the link 33. At this time, the supporter extension 322 may be in a state of being in simple contact with the first part 331, that is, a state of not pressing for rotation of the link 33. For example, the front end of the supporter extension 322 may come into contact with the lower surface of the first part 331. In addition, the shock absorbing member 336 may come into contact with the handle portion 252.
In addition, the upper end of the link 33 maintains a contact state with the push member 34. For example, an upper end of the rear surface of the second part 332 may come into contact with the front surface of the pressing portion 342. In addition, the first part 331 may maintain a state parallel to the front surface of the door 20 and/or a state perpendicular to the upper surface of the freezing chamber door 22. In addition, the first part 331 may be parallel to the operating member 31.
Meanwhile, the push member 34 may be moved most forward by the elastic force provided by the elastic member 346. In addition, the pressing portion 342 and the second part 332 may maintain a contact state, and the first part 331 and the supporter extension 322 may maintain a contact state.
Further, the protruding length H1 of the push member 34 from the rear surface of the upper cap decoration 25 to the rear end of the push member 34 may correspond to the thickness of the gasket 27. Accordingly, the rear end of the push member 34 may come into contact with the front surface of the cabinet 10 or the front surface of the barrier 11 before the operating member 31 is operated.
In this state, as soon as the operating member 31 is operated, the push member 34 moves backward and pushes the front surface of the cabinet 10 or the barrier 11 to assist in opening the freezing chamber door 22.
In a state where the freezing chamber door 22 is closed, the user may open the freezing chamber door 22 by holding and pulling the handle 250. In this case, the operating member 31 may be disposed at an eccentric position toward the front surface of the freezing chamber door 22 based on the center of the handle 250. In addition, the operating member 31 may be disposed on the front surface of the inner surface of the handle 250.
Therefore, when the user puts his/her hand into the handle 250 and pulls the handle, the user can naturally operate the operating member 31 inside. That is, the operation of the door opening device 30 and the operation of drawing the freezing chamber door 22 out can be performed at one time only by holding and pulling the handle 250 without additional operation.
In detail, when a user puts his/her hand into the handle 250 to open the freezing chamber door 22 and grasps the front upper end of the freezing chamber door 22, the user's hand naturally comes into contact with the operating member 31. In addition, the operating member 31 is located on the front surface of the inner surface of the handle 250, and the operating member 31 can be pressed while pulling the freezing chamber door 22.
As illustrated in
In a state where the operating member 31 is fully rotated in a clockwise direction, the rear surface of the operating member 31 may be accommodated inside the handle opening 253. In addition, the lower protrusion 311b may be spaced apart from the guide protrusion 252a. When the operating member 31 is operated, the operating member 31 may cross the front surface of the door 20.
Meanwhile, when the operating member 31 rotates clockwise, the front end of the supporter extension 322 pushes the first part 331 upward, and the link 33 is rotated counterclockwise with respect to the link rotation shaft 334.
By the rotation of the link 33, the upper end of the second part 332 presses the pressing portion 342 of the push member 34 from the front to the rear. The rotation of the link 33 causes the push member 34 to move backward, and in this process, the elastic member 346 may be compressed. In addition, the rear end of the push member 34 pushes the front surface of the cabinet 10 or the front surface of the barrier 11.
At this time, the protruding length H2 of the push member 34 from the rear surface of the upper cap decoration 25 to the rear end of the push member 34 is greater than the protruding length H1 of
In addition, when the user releases his/her hand from the operating member 31 in a state where the opening operation of the freezing chamber door 22 is completed, the push member 34 is moved forward by the elastic restoring force of the elastic member 346, in this process, the link 33 rotates clockwise, and the operating member 31 moves counterclockwise to automatically return to the state before operation of the operating member 31 as illustrated in
