The terminal installation part 30 is accommodated in the entrance opening 21, and various parts including the terminal installation part 30, the slide plate 50, the driving part 60, etc., are mounted therein. The terminal installation part 30 is provided with a couple of guide rods 31, 32 guiding the slide plate 50 to slidingly move, and an installation frame 33, 34 to which the guide rod 31, 32 are mounted respectively, in the opposite inner sides thereof. Also, the terminal installation part 30 is provided with a supporting member 80 supporting a bottom portion of the terminal 40 and rotating between an installing state and a separating state of the terminal 40 in a bottom area thereof.
A rotation shaft 81 is mounted to bottom opposite sides of the supporting member 80, and is rotatably supported by a rotation shaft supporter 37 provided to the terminal installation part 30. Also, a spring 82 is provided to a bottom portion of the supporting member 80 and supplies an elastic force to the supporting member 80.
The slide plate 50 comprises a first slide plate 51 and a second slide plate 52, which are provided to opposite sides of the terminal 40. A connecting member 35, 36 is interposed between the guide rod 31, 32 and the slide plate 51, 52 and connects the slide plate 51, 52 with the guide rod 31, 32.
As the slide plate 51, 52 ascends and descends, the connecting member 35, 36 may ascend and descend integrally therewith relative to the guide rod 31, 32.
The holding part 53, 56 is provided to each top portion of the first slide plate 51 and the second slide plate 52.
A first auxiliary rack gear 55 is formed in an upper side of the first slide plate 51. Below the first auxiliary rack gear 55 is formed a rack gear 54 engaged with a pinion gear 62. Also, in an inner plate surface of the first slide plate 51 is formed an ascending groove 51 a along an up and down direction guiding a guide pin 91 as the first slide plate 51 ascends and descends, and from the ascending groove 51 a along a declined direction is prolonged a second guiding groove 51 b guiding the guide pin 91 as a cover plate 85 moves forward along a first guiding groove 94 b in FIG. 6.
A second auxiliary rack gear 57 is formed in an upper side of the second slide plate 52. Also, in an inner plate surface of the second slide plate 52 is formed an ascending groove 52 a along an up and down direction guiding a guide pin 92 as the second slide plate 52 ascends and descends, and from the ascending groove 52 a along a declined direction is prolonged a second guiding groove 52 b guiding the guide pin 92 as the cover plate 85 moves forward along the first guiding groove 94 b in FIG. 6.
The holding part 53, 56 comprises a holding projection 53 a, 56 a holding a top portion of the terminal 40, and a holding spring 53 b, 56 b elastically pressing the holding projection 53 a, 56 a. With correspondence thereto in the top portion of the terminal 40 is formed a projection container 40 a, 41 a (see FIG. 4) containing the holding projection 53 a, 56 a. Hence, the holding projection 53 a, 56 a may be inserted into the projection container 40 a, 41 a, thereby the terminal 40 may be maintained to be held by the terminal installation part 30.
The driving part 60 comprises a driving motor 61 provided to the installation frame 33 and supplying a rotating force, the pinion gear 62 connected with the driving motor 61, and the rack gear 54 formed in the first slide plate 51 and engaged with the pinion gear 62.
The driving motor 61 is provided to a side of the first slide plate 51, and a driving gear 61 a is provided to a shaft thereof.
Since the driving gear 61 a is engaged with the pinion gear 62, the driving gear 61 a rotates counterclockwise while the pinion gear 62 rotates clockwise. Hence, the first slide plate 51 provided with the rack gear 54 may move straight upward by a rotating force of the pinion gear 62. Herein, because of being provided with the ascending groove 51 a, the first slide plate 51 may move upward without interference of the guide pin 91.
Herein, it is preferable, but not necessary, that a lever unit 70 may be provided to a top area of the terminal installation part 30. The lever unit 70 pushes the terminal 40 along a separating direction as the terminal 40 is out of hold by the driving part 60. Thereby, the user may separate the terminal 40 from the terminal installation part 30 without difficulty because the terminal 40 is in a pushed state along the separating direction.
The lever unit 70 comprises a turning shaft 71 coupled to the terminal installation part 30, a lever 72 integrally coupled to the turning shaft 71 and pressing the terminal 40 along the separating direction, and a lever turning part 73 turning the turning shaft 71 and the lever 72.
The turning shaft 71 is rotatably coupled to a turning supporting part 38 provided to the terminal installation part 30.
The lever 72 is coupled to the turning shaft 71, contacts with a rear surface of the terminal 40, and integrally turns with the turning shaft 71. Hence, the lever 72 may push the terminal 40 forward accordingly as the turning shaft 71 and the lever 72 turn clockwise.
The lever turning part 73 comprises a first lever gear 74 coupled to a first end portion of the turning shaft 71, and the first auxiliary rack gear 55 formed in the upper side of the first slide plate 51 and engaged with the first lever gear 74. As the first slide plate 51 slidingly moves upward by driving of the driving motor 61, the first auxiliary rack gear 55 turns the first lever gear 74 clockwise, thereby the turning shaft 71 and the lever 72 may integrally turn in a turning direction of the first lever gear 74.
Also, a second lever gear 75 is coupled to a second end portion of the turning shaft 71, and the second auxiliary rack gear 57 is formed in the second slide plate 52 engaged with the second lever gear 75. Hence, a turning force of the first lever gear 74 is delivered to the turning shaft 71 and the second lever gear 75, thereby the second lever gear 75 moves the second slide plate 52 slidingly upward. Hence, the rotating force of the single driving motor 61 makes it possible that the first slide plate 51 slidingly moves upward, the turning shaft 71 turns, the lever 72 and the second lever gear 75 turns, and the second slide plate 52 also slidingly moves upward. Herein, as formed with the ascending groove 52 a, the second slide plate 52 may move upward without interference of the guide pin 92. Thereby, each holding part 53, 56 of the first slide plate 51 and the second slide plate 52 releases the terminal 40, and simultaneously the lever 72 presses the terminal 40 along the separating direction. As a result, the terminal 40 is tilted forward with a predetermined angle on the rotation shaft 81 of the supporting member 80, thereby getting in a state that the user may separate the terminal without difficulty.
Herein, as shown in FIGS. 6 through 9, preferably, but not necessarily, the refrigerator 1 may further comprise the cover plate 85 movably provided to the terminal installation part 30 and opening/closing the entrance opening 21, and a transferring part 90, 95 transferring the cover plate 85 along an opening/closing direction to open/close the entrance opening 21. Hence, the cover plate 85 may close the entrance opening 21 after the terminal 40 is separated from the entrance opening 21, which serves to provide the refrigerator 1 with a good external appearance.
It is preferable, but not necessary, that the cover plate 85 is disposed behind the terminal 40 and formed to correspond with a configuration of the entrance opening 21.
The transferring part 90, 95 forms a pair to be symmetrically disposed at opposite sides of the cover plate 85, and only the transferring part 95 of a left side of the second slide plate 52 will be described for convenience.
The transferring part 95 comprises the guide pin 92 coupled to the cover plate 85, a guiding bracket 94 interposed between the cover plate 85 and the second slide plate 52 and formed with the first guiding groove 94 b guiding the guide pin 92 along the opening/closing direction of the cover plate 85, and the second guiding groove 52 b formed in the second slide plate 52 and guiding the guide pin 92 so that the cover plate 85 moves along the first guiding groove 94 b as the second slide plate 52 slidingly moves by the driving motor 61. Namely, as the second slide plate 52 slidingly moves upward thereby, the guide pin 92 moves forward along the first guiding groove 94 b by an ascending force of the second slide plate 52. Hence, the cover plate 85 may slidingly move forward integrally with the guide pin 92 and close the entrance opening 21.
Hereinafter, a process will be described wherein the terminal 40 is being separated from the entrance opening 21 in the refrigerator 1 according to the present invention.
As shown in FIGS. 2 through 5, at first, the terminal 40 is held to the terminal installation part 30 by the holding part 53, 56. After that, if the user pushes the operating button 22 to separate the terminal 40, the driving motor 61 operates to rotate the driving gear 61 a counterclockwise. Also, the pinion gear 62 engaged with the driving gear 61 a rotates clockwise and delivers a force to the rack gear 54. Also, the first slide plate 51 slidingly moves upward to turn the first lever gear 74 engaged with the first auxiliary rack gear 55. The holding part 53 of the first slide plate 51 releases the terminal 40. Also, as the turning force of the first lever gear 74 is delivered to the turning shaft 71 and the lever 72, the lever 72 pushes the terminal 40 forward with a predetermined angle and the second lever gear 75 moves the second slide plate 52 slidingly upward turning in the same direction as the first lever gear 74 turns. At this time, the guide pins 91, 92 coupled to the first slide plate 51 and the second slide plate 52 may be guided along the each ascending groove 51 a, 52 a. With this process, the terminal 40 may be tilted forward with a predetermined angle on the rotation shaft 81 of the supporting member 80, and the user may separate the terminal 40 from the terminal installation part 30 without difficulty.
Hereinafter, a process will be described wherein the cover plate 85 is closing the entrance opening 21 in the refrigerator 1 according to the present invention.
As shown in FIGS. 6 through 9, as the terminal 40 is separated from the terminal 40, the driving motor 61 operates again after a predetermined time. Then, the first slide plate 51 and the second slide plate 52 keep slidingly moving upward, and the guide pins 91, 92 are pressed forward by the second guiding groove 51 b, 52 b, respectively. Accordingly, the cover plate 85 coupled with the guide pins 91, 92 slidingly moves forward along the first guiding grooves 94 b of the guiding brackets 93, 94 and closes the entrance opening 21. With this process, the entrance opening 21 from which the terminal 40 is separated is closed by the cover plate 85, which serves to enhance the beauty of an external appearance of the refrigerator 1.
In the foregoing embodiment, the terminal is installed to the door, but the terminal may be installed to the main body cabinet, or to both the door and the main body cabinet.
In the foregoing embodiment, the single driving part is provided to operate both the first slide plate and the second slide plate, but a plurality of driving parts may be provided to operate the first slide plate and the second slide plate, respectively.
In the foregoing embodiment, the single operating button is provided for both installing and separating of the terminal, but a plurality of operating buttons may be provided for installing and separating of the terminal, respectively.
Although a few exemplary embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
