Embodiments relate to a refrigerator including the ice bank fixation device.
Generally, refrigerators are used to keep food at a low temperature. Such a refrigerator includes a body in which a storage chamber is formed, and a door attached to the body for opening/closing the storage chamber.
An icemaker and an ice bank can be provided in the storage chamber for making and storing ice. The ice bank includes an ice carriage lever and an ice carriage motor. The ice carriage lever is driven by the ice carriage motor for moving the ice stored in the ice bank to a dispenser.
In this case, the storage capacity of the storage chamber may be reduced due to the ice bank. Moreover, the ice stored in the ice bank can be discharged only through the dispenser using the ice carriage lever. That is, a user cannot eject the ice directly from the ice bank. A refrigerator comprising an ice bank is known from
Embodiments provide a refrigerator including the ice bank fixation device so that a storage chamber of the refrigerator can be less occupied by an ice bank.
Embodiments also provide a refrigerator including the ice bank fixation device that allows a user to take ice automatically or manually from an ice bank.
The solution to the problem is a refrigerator according to claim 1.
According to embodiments, the ice bank is attached to the backside of the re-frigerator door so that the ice bank may occupy less of a storage chamber of the re-frigerator, and thus more food can be stored in the storage chamber.
In addition, the ice bank can be attached to and detached from the refrigerator door more easily owing to the ice bank fixation device, and thus a user can take ice automatically from the ice bank through a dispenser or manually from the ice bank after detaching the ice bank from the backside of the refrigerator door.
Embodiments can be understood more clearly from the accompanying drawings.
Reference will now be made in detail to the embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings.
Referring to
An outer door 53 is formed on a front outer portion of the refrigerator door 50. A door liner 55 is coupled to an inner surface of the outer door 53 to form the backside of the refrigerator door 50. Supports 56 are formed on both sides of the backside of the refrigerator door 50. The supports 56 extend backward from the door liner 55 and have a vertically elongated shape.
At least one pair of second coupling parts 57 is formed at mutually facing surfaces of the supports 56. The second coupling parts 57 are formed for receiving first coupling parts 71 (described later). The second coupling parts 57 are formed at corresponding positions of the mutually facing surfaces of the supports 56. The second coupling parts 57 may be recesses formed in the mutually facing surfaces of the supports 56.
A receiving surface 58 is formed at the backside of the refrigerator door 50. The receiving surface 58 is formed by backwardly extending a portion of the door liner 55 located between the supports 56. The receiving surface 58 extends backward more than the supports 56.
The receiving surface 58 includes an opening 59. Ice stored in an ice storage space 60S (described later) of the ice bank 60 is carried to the dispenser 51 through the opening 59.
The ice bank 60 and an icemaker 40 are detachably coupled to the backside of the refrigerator door 50. The icemaker 40 is disposed above the ice bank 60.
When the ice bank 60 is coupled to the backside of the refrigerator door 50, both sides of the ice bank 60 make tight contact with the mutually facing surfaces of the supports 56, and a bottom surface of the ice bank 60 makes contact with the receiving surface 58. Therefore, the ice bank 60 can be first fixed in lateral direction by the supports 56.
Ice produced by the icemaker 40 is stored in the ice storage space 60S of the ice bank 60. The ice storage space 60S has an opened top portion.
The ice stored in the ice storage space 60S of the ice bank 60 is carried to the dispenser 51 and discharged to a user through the dispenser 51.
In detail, the ice bank 60 includes an ice outlet 63 in a bottom surface for discharging ice. The ice outlet 63 is formed at a position corresponding to the position of the opening 59 of the receiving surface 58. An icebreaker 61 is disposed in the ice bank 60 for breaking the ice stored in the ice storage space 60S into parts having a predetermined size and carrying the broken ice to the dispenser 51. The icebreaker 61 is disposed above and close to the ice outlet 63.
An icebreaker motor (not shown) drives the icebreaker 61. The icebreaker motor is disposed at a side of the icebreaker 61. Alternatively, the icebreaker motor can be disposed at the refrigerator door 50 and connected to the icebreaker 61 through an additional linkage member.
The ice outlet 63 is closed or opened according to the operation of the icebreaker 61. In detail, when the icebreaker 61 operates, ice stored in the ice storage space 60S is carried to the dispenser 51 through the ice outlet 63 and the opening 59. When the icebreaker 61 does not operate, the ice outlet 63 is substantially closed by the icebreaker 61.
The icebreaker 61 includes a window 65. The window 65 is formed of a transparent or semitransparent material. Therefore, a user can check the amount of ice stored in the ice storage space 60S through the window 65.
Rotation spaces 67 are formed in both sides of the ice bank 60 to allow rotation of the first coupling parts 71. The rotation spaces 67 may be recesses formed in both sides of the ice bank 60.
The number of the first coupling parts 71 of the ice bank 60 is at least two (a pair), and the first coupling parts 71 are rotatably disposed in the rotation spaces 67, respectively. When the ice bank 60 is attached to the backside of the refrigerator door 50, the first coupling parts 71 are coupled to the second coupling parts 57 so that the ice bank 60 can be stably locked on the backside of the refrigerator door 50.
Both ends of each of the first coupling parts 71 can be rotated about a shaft 71H that is vertically disposed in the rotation space 67. Alternatively, shafts can be integrally formed on the first coupling parts 71, respectively, and insertion holes can be formed in the ice bank 60 for receiving the shafts.
Coupling tabs 73 extend outward from front ends of the first coupling parts 71 that are adjacent to the backside of the refrigerator door 50. The coupling tab 73 can be inserted into the second coupling parts 57 by rotating the first coupling parts 71 about the shafts 71H. Guide surfaces 74 are formed on outer surfaces of the coupling tabs 73, respectively. When the ice bank 60 is coupled to the backside of the refrigerator door 50, the coupling tab 73 can be smoothly inserted into the second coupling parts 57 owing to the guide surfaces 74. The guide surfaces 74 can have a rounded shape.
Levers 75 are formed on rear ends of the first coupling parts 71. A user can pull the levers 75 to rotate the first coupling parts 71 on the shafts 71H. For example, the levers 75 can be curved from the rear ends of the first coupling parts 71 away from the ice bank 60 so as to be placed outside the rotation spaces 67. When the ice bank 60 is coupled to the refrigerator door 50, the levers 75 are protruded outward from the ice bank 60 so that a user can pull the levers 75.
Torsion springs 77 are disposed at the shafts 71H, respectively. One end of the torsion spring 77 is supported by a side of the ice bank 60, and the other end of the torsion spring 77 is supported by a side of the first coupling part 71. When the first coupling part 71 is coupled to the second coupling part 57, the torsion spring 77 elastically forces the coupling tab 73 to rotate into the second coupling part 57. For example, one end of the torsion spring 77 can be supported by the ceiling of the rotation space 67, and the other end of the torsion spring 77 can be supported by the front end of the first coupling part 71.
Hereinafter, an ice bank fixation device, a refrigerator including the ice bank fixation device, and how the ice bank 60 is attached/detached to/from the refrigerator will be described in detail with reference to the accompanying drawing.
Referring to
Therefore, the ice bank 60 is not unintentionally detached from the backside of the refrigerator door 50.
In this state, when a user manipulates the dispenser 51, the icebreaker 61 operates to discharge ice stored in the ice storage space 60S of the ice bank 60 to the outside through the dispenser 51. Therefore, the user can get ice without opening the refrigerator door 50.
Meanwhile, the ice bank 60 can be detached from the refrigerator door 50 by disengaging the first coupling parts 71 from the second coupling parts 57 as shown in
In this state, the ice bank 60 can be detached from the backside of the refrigerator door 50 by pulling the ice bank 60 away from the backside of the refrigerator door 50 as shown in
After the ice bank 60 is detached from the refrigerator door 50, the first coupling parts 71 can rotate to their original positions by releasing the levers 75. Since the ice outlet 63 of the ice bank 60 is screened by the icebreaker 61, ice is not undesirably discharged through the ice outlet 63.
Meanwhile, the detached ice bank 60 can be attached to the backside of the refrigerator door 50 again by repeating the above-described procedures in a reverse order. In this case, it is not necessary to pull the levers 75.
In the current embodiment, the ice bank 60 is directly attached to the backside of the refrigerator door 50. However, other structures can be used for attaching the ice bank 60 to the refrigerator door 50. For example, an additional accommodation member can be disposed to the backside of the refrigerator door 50, and the ice bank 60 and the icemaker 40 can be attached to the accommodation member.
In addition, the second coupling parts 57 are formed at the refrigerator door 50, and the first coupling parts 71 are formed at the ice bank 60 in the current embodiment. However, the second coupling parts 57 can be formed at the ice bank 60, and the first coupling parts 71 can be formed at the refrigerator door 50.
Referring to
In detail, the coupling protrusions 81 are formed on supports 56. The coupling protrusions 81 can be vertically arranged on the supports 56. The protrusion insertion holes 82 are formed in the ice bank 60 at positions corresponding to those of the coupling protrusions 81.
When the ice bank 60 is attached to the refrigerator door 50, the coupling protrusions 81 are inserted into the protrusion insertion holes 82 so that the ice bank 60 can be fully fixed to the refrigerator door 50.
In the current embodiment, the coupling protrusions 81 are formed on the refrigerator door 50, and the protrusion insertion holes 82 are formed in the ice bank 60. However, the coupling protrusions 81 can be formed on the ice bank 60, and the protrusion insertion holes 82 can be formed in the refrigerator door 50.
Referring to
In detail, the first coupling parts 85 can have a horizontally elongated shape and arranged in a vertical direction. The second coupling parts 86 can have a horizontally elongated recess shape and arranged in a vertical direction.
Therefore, the first coupling parts 85 can slide into the second coupling part 86 by pushing the ice bank 60 toward the refrigerator door 50 after aligning the first coupling parts 85 with the second coupling parts 86. In this way, the ice bank 60 can be coupled to the refrigerator door 50.
The first coupling parts 85 have a size corresponding to that of the second coupling parts 86, and the first and second coupling parts 85 and 86 are arranged in a vertical direction. Therefore, after the ice bank 60 is coupled to the refrigerator door 50, the ice bank 60 is not readily detached from the refrigerator door 50 when the refrigerator door 50 is opened and closed.
Referring to
In detail, the magnetic member 91 can be disposed on at least one portion of the ice bank 60. In
According to the current embodiment, a structure for attaching the ice bank 60 to the refrigerator door 50 is not exposed to the outside for aesthetical improvement.
When the ice bank 60 is attached to the refrigerator door 50, the ice bank 60 makes contact with a door liner 55 of the refrigerator door 50. Thus, in the case where the door liner 55 is formed of a material to which the magnetic member 91 can be magnetically attached, the metal member 92 can be omitted from the refrigerator door 50.
Alternatively, the metal member 92 can be disposed at a bottom surface of an icemaker 40. In this case, the magnetic member 91 may be disposed on a top portion of the ice bank 60. Therefore, the refrigerator door 50 can be placed on a receiving surface 58 and firmly held at that position by a magnetic force between the metal member 92 of the icemaker 40 and the magnetic member 91 of the ice bank 60.
Referring to
The latch hook 95 can be coupled to the latch slot 96 by pushing the latch hook 95 against the latch slot 96, and the latch hook 95 can be released from the latch slot 96 by pushing the latch hook 95 against the latch slot 96 again. Since this coupling structure is well known, a detailed description thereof will be omitted.
Meanwhile, alternatively, the latch slot 96 can be formed in the ice bank 60, and the latch hook 95 can be formed on the refrigerator door 50.
According to embodiments, an ice bank can be detachably attached to a refrigerator door using the ice bank fixation device. Therefore, a user can take ice automatically from the ice bank through a dispenser or manually from the ice bank after detaching the ice bank from the backside of the refrigerator door, and thus the refrigerator including the ice bank fixation device can be used in various industrial fields.
