- the refrigerating chamber and the freezing chamber may be positioned in upper and lower parts of the body 10 , respectively.
- the refrigerating chamber and the freezing chamber may be positioned in left and right parts of the body 10 , respectively.
- the refrigerating chamber and the freezing chamber arranged side by side thus can be lager than the refrigerating chamber and the freezing chamber arranged in upper and lower parts. Consequently, according to the user's requirement for large refrigerating, and freezing chambers, currently, many refrigerators have such refrigerating, and freezing chambers standing side by side. In more detail, as shown in FIG.
- the refrigerating chamber is arranged in a right part of the body 10
- the freezing chamber is arranged in left part of the body 10 .
- the body 10 has a freezing chamber door, and refrigerating chamber door 20 a , and 20 b for opening/closing such freezing chamber, and refrigerating chamber, respectively.
- hand grips are provided to the doors 20 a , and 20 b.
- the refrigerator of the present invention includes a dispenser 30 , and a supplementary storage device 100 for providing additional convenience to the user.
- the dispenser 30 connected to an icemaker (not shown) and a water supply source inside of the freezing chamber, supplies ice and cold water to the user without opening the freezing chamber door 20 a , directly.
- the supplementary storage device 100 enables the user directly to put a predetermined amount of food therein, or to take out a predetermined amount of food therefrom, without opening the refrigerating chamber door 20 b , conveniently.
- the supplementary storage device 100 is often called as a refrigerator ‘home bar’. Since the dispenser 30 is identical to a general refrigerator dispenser, detailed description of which will be omitted, while the supplementary storage device 100 is described in more detail.
- the supplementary storage device 100 includes an opening 110 in the door 20 b , a supplementary door 120 on the opening 110 , and a damper 130 between the door 120 and the opening 110 .
- the opening 110 formed by making a hole in the door 20 b actually, enables an inside space of the refrigerator, more specifically, the refrigerating chamber, to communicate with an outside of the refrigerator through the opening 110 . Therefore, the user can put food in, or take out food from the refrigerating chamber through the opening 110 , directly.
- the opening 110 may be configured to be in communication with the freezing chamber for putting frozen food in or taking frozen food out of the freezing chamber. In this case, the opening 110 is formed in the freezing chamber door 20 a .
- the opening 110 can be selectively formed in the doors 20 a , or 20 b depending on a storage temperature at which the food is required to be stored by using the supplementary storage device.
- the supplementary shelf 110 a By using, not the shelves in the refrigerating chamber, but the supplementary shelf 110 a , the user can put food in the refrigerator through the opening 110 , or can take out food from the refrigerator through the opening 110 , more conveniently.
- a fence 110 b may be formed at an edge of the supplementary shelf 110 a for preventing long drink containers or food on the supplementary shelf from dropping therefrom.
- an additional cover may be extended from the fence 110 b to enclose the drink containers and food, entirely.
- the opening 110 in communication with the refrigerating chamber (or the freezing chamber)
- at least a portion of the refrigerating chamber (or the freezing chamber) can be served as an independent storage chamber only for the supplementary storage device 100 .
- the supplementary door 120 is configured to open or close the opening 110 . That is, the supplementary door 120 opens the opening 110 when the user takes food out of the refrigerator, or puts food into the refrigerator, then closes the opening 110 for preventing the cold air from escaping through the opening 110 .
- the supplementary door 120 is fastened to the door 20 b , such that the supplementary door 120 is rotatable about a bottom edge of the supplementary door 120 . Therefore, the supplementary door 120 rotates to open the opening 110 by gravity easily, even if no additional force is applied to the supplementary door 120 .
- the supplementary door 120 is opened in a horizontal position for placing food thereon.
- the user may put food piece by piece inside of the refrigerating chamber, conveniently.
- the user may take out food through the opening 110 , set on the rear surface 120 of the supplementary door 120 , for eating.
- the supplementary door has a hand grip 120 a on a front surface for rotating the supplementary door 120 , easily.
- the supplementary door 120 has a hook 121 on a top
- the opening 10 has a holder 111 on a top of the opening 10 in correspondence to the hook 121 . Therefore, as the hook 121 is engaged with the holder 111 , the supplementary door 120 is kept to close the opening 110 . Also, the hook is linked with the hand grip 120 a . Therefore, if the user pulls the hand grip 120 a , the hook 121 is released from the holder 111 , such that the supplementary door 120 is rotated, to open the opening 110 .
- the damper 130 is joined with the refrigerator door 20 b such that the supplementary door 120 is rotatable. That is, basically, the damper 130 serves as a hinge for rotatably joining the supplementary door 120 to the refrigerator door 20 b . In more detail, as described before, for making the supplementary door 120 to rotate around the bottom edge thereof, the damper 130 couples the lower edge of the supplementary door 120 to the refrigerator door 20 b .
- the damper 130 may be provided only to one of the opposite side surfaces of the supplementary door 120 , while a general link mechanism, or hinge is provided to the other side surface.
- the dampers 130 are provided to the opposite side parts of the bottom edge of the supplementary door 120 . As shown, the dampers 130 are arranged along an axis passing through the bottom edge of the supplementary door 120 , so that at least a part of the damper 130 rotates together with the supplementary door 120 . In the meantime, in a case the supplementary door 120 is coupled to the door 20 b only with the damper 130 , coupling between the supplementary door 120 and the door 20 b may be weak. Therefore, the supplementary door 120 may further include a hinge shaft 122 projected from a side surface thereof, for firm joining of the supplementary door 120 with the damper 130 . For firmer joining, the hinge shaft 122 may be rotatably inserted in the door 20 b.
- the damper 130 is configured to damp a rotation force generated when the supplementary door 120 is opened or closed.
- a damping force of the damper 130 at the time of opening of the supplementary door 130 is greater than a damping force of the damper 130 at the time of closing the supplementary door 120 , because the supplementary door 120 is opened at a high speed by gravity.
- the damper 130 may be fabricated with an elastic member for generating the damping force. That is, if the supplementary door 120 rotates, the elastic member in the damper 130 deforms to absorb the rotation force of the supplementary door 120 .
- such an elastic member causes permanent deformation due to repetitive deformation, failing to maintain a required damping force.
- the damper 130 employs oil for generating the damping force.
- the oil damper 130 since an oil damper 130 can keep supplying a uniform damping force, the oil damper 130 is effective for damping the supplementary door 110 that is opened/closed frequently.
- a preferred embodiment of the oil damper 130 will be described with reference to FIGS. 4 and 5. Besides the oil damper illustrated, different kinds of dampers known to this field of art can be applicable to the present invention.
- the damper 130 includes a case 131 , and a rotation shaft 132 rotatably mounted in the case 131 .
- the case 131 is filled with an amount of oil ‘O’, and sealed for preventing the oil ‘O’ from leaking therefrom.
- the rotation shaft 132 is projected from the case 131 , partly.
- the rotation shaft 132 is configured to generate a friction force or a hydraulic force together with the oil ‘O’.
- the rotation shaft 132 has projections 132 a configured to contact with the oil ‘O’ in the case directly. That is, the projections 132 a are formed on a part of the rotation shaft 132 positioned inside of the case 131 .
- the projections 132 a may be a gear or a screw formed continuously on the rotation shaft 132 . Since the oil ‘O’ has a certain viscosity, if the rotation shaft 132 rotates, a predetermined friction force acts on the projections 132 a in contact with the oil ‘O’. The friction force acts in a direction opposite to a rotation direction of the rotation shaft 132 , to give a torque in a direction opposite to the rotation direction of the rotation shaft 132 .
- supplementary projections may be formed on an inside circumferential surface of the case 131 too extended between the projections 132 a .
- a closed channel is formed between adjacent projection 132 a and the supplementary projection, to dampen the rotation force of the rotation shaft by using a hydraulic pressure in the channel.
- the oil damper 130 , the case 131 is fixed to the door 20 b , and the rotation shaft 132 is fixed to the supplementary door 120 . If the supplementary door 120 had the hinge shaft 122 , the rotation shaft 132 is joined with the hinge shaft 122 . Accordingly, in opening and closing the supplementary door 120 , the rotation shaft 132 rotates relative to the case 131 together with the supplementary door 120 , while the rotation shaft 132 dampens the rotation force of the supplementary door 120 .
- the user opens the door 120 .
- the hook 121 is released from the holder 111 , and, then, the door 120 rotates downwardly around the bottom edge thereof by gravity.
- the supplementary door 120 rotates slowly owing to the damping force of the damper 130 , enough to give no impacts to the door 20 b , the damper 130 , and the supplementary door itself when the supplementary door 120 is rotated, fully.
- the opening 110 is opened fully by rotation of the door 120 , the user puts food into the refrigerator, or takes out food from the refrigerator. Or, the user may take out, and set food on the rear surface 120 b of the supplementary door 120 for eating.
- the use of the damper 130 in the supplementary storage device 100 of the present invention permits damping of a rotation force of the supplementary door 120 , to drop an opening speed of the supplementary door 120 , significantly.
- the damping action minimizes impact, vibration, and noise caused by the supplementary storage device 100 , and minimizes damage to different components of the supplementary storage device 100 . According to this, lifetime and stability of the supplementary storage device 100 are increased, and reliability and satisfaction of the user for the supplementary storage device are increased.

Consequently, according to the user's requirement for large refrigerating, and freezing chambers, currently, many refrigerators have such refrigerating, and freezing chambers standing side by side. In more detail, as shown in FIG. 1, the refrigerating chamber is arranged in a right part of thebody 10, and the freezing chamber is arranged in left part of thebody 10. Thebody 10 has a freezing chamber door, and refrigeratingchamber door doors - Moreover, the refrigerator of the present invention includes a
dispenser 30, and asupplementary storage device 100 for providing additional convenience to the user. Thedispenser 30, connected to an icemaker (not shown) and a water supply source inside of the freezing chamber, supplies ice and cold water to the user without opening thefreezing chamber door 20 a, directly. Thesupplementary storage device 100 enables the user directly to put a predetermined amount of food therein, or to take out a predetermined amount of food therefrom, without opening the refrigeratingchamber door 20 b, conveniently. Thesupplementary storage device 100 is often called as a refrigerator ‘home bar’. Since thedispenser 30 is identical to a general refrigerator dispenser, detailed description of which will be omitted, while thesupplementary storage device 100 is described in more detail. - Referring to FIG. 3, the
supplementary storage device 100 includes anopening 110 in thedoor 20 b, asupplementary door 120 on theopening 110, and adamper 130 between thedoor 120 and theopening 110. - The
opening 110, formed by making a hole in thedoor 20 b actually, enables an inside space of the refrigerator, more specifically, the refrigerating chamber, to communicate with an outside of the refrigerator through theopening 110. Therefore, the user can put food in, or take out food from the refrigerating chamber through theopening 110, directly. In FIGS. 2 and 3, though theopening 110 is shown to be in communication with the refrigerating chamber, theopening 110 may be configured to be in communication with the freezing chamber for putting frozen food in or taking frozen food out of the freezing chamber. In this case, theopening 110 is formed in the freezingchamber door 20 a. That is, theopening 110 can be selectively formed in thedoors supplementary shelf 110 a close to a bottom edge of theopening 110 on a rear surface of thedoor 20 b opposite to the refrigerating chamber. By using, not the shelves in the refrigerating chamber, but thesupplementary shelf 110 a, the user can put food in the refrigerator through theopening 110, or can take out food from the refrigerator through theopening 110, more conveniently. Moreover, afence 110 b may be formed at an edge of thesupplementary shelf 110 a for preventing long drink containers or food on the supplementary shelf from dropping therefrom. More preferably, though not shown, an additional cover may be extended from thefence 110 b to enclose the drink containers and food, entirely. At the end, as described before, owing to theopening 110 in communication with the refrigerating chamber (or the freezing chamber), at least a portion of the refrigerating chamber (or the freezing chamber) can be served as an independent storage chamber only for thesupplementary storage device 100. - The
supplementary door 120 is configured to open or close theopening 110. That is, thesupplementary door 120 opens theopening 110 when the user takes food out of the refrigerator, or puts food into the refrigerator, then closes theopening 110 for preventing the cold air from escaping through theopening 110. Thesupplementary door 120 is fastened to thedoor 20 b, such that thesupplementary door 120 is rotatable about a bottom edge of thesupplementary door 120. Therefore, thesupplementary door 120 rotates to open theopening 110 by gravity easily, even if no additional force is applied to thesupplementary door 120. Preferably, as shown in FIG. 3, thesupplementary door 120 is opened in a horizontal position for placing food thereon. Therefore, after placing may pieces of food on therear surface 120 b of thesupplementary door 120, the user may put food piece by piece inside of the refrigerating chamber, conveniently. On the other hand, the user may take out food through theopening 110, set on therear surface 120 of thesupplementary door 120, for eating. - Referring to FIG. 2, the supplementary door has a
hand grip 120 a on a front surface for rotating thesupplementary door 120, easily. As shown in FIG. 3, thesupplementary door 120 has ahook 121 on a top, and theopening 10 has aholder 111 on a top of theopening 10 in correspondence to thehook 121. Therefore, as thehook 121 is engaged with theholder 111, thesupplementary door 120 is kept to close theopening 110. Also, the hook is linked with thehand grip 120 a. Therefore, if the user pulls thehand grip 120 a, thehook 121 is released from theholder 111, such that thesupplementary door 120 is rotated, to open theopening 110. - Primarily, the
damper 130 is joined with therefrigerator door 20 b such that thesupplementary door 120 is rotatable. That is, basically, thedamper 130 serves as a hinge for rotatably joining thesupplementary door 120 to therefrigerator door 20 b. In more detail, as described before, for making thesupplementary door 120 to rotate around the bottom edge thereof, thedamper 130 couples the lower edge of thesupplementary door 120 to therefrigerator door 20 b. In thesupplementary storage device 100, thedamper 130 may be provided only to one of the opposite side surfaces of thesupplementary door 120, while a general link mechanism, or hinge is provided to the other side surface. However, it is preferable that for more reliable damping, it is preferable that thedampers 130 are provided to the opposite side parts of the bottom edge of thesupplementary door 120. As shown, thedampers 130 are arranged along an axis passing through the bottom edge of thesupplementary door 120, so that at least a part of thedamper 130 rotates together with thesupplementary door 120. In the meantime, in a case thesupplementary door 120 is coupled to thedoor 20 b only with thedamper 130, coupling between thesupplementary door 120 and thedoor 20 b may be weak. Therefore, thesupplementary door 120 may further include ahinge shaft 122 projected from a side surface thereof, for firm joining of thesupplementary door 120 with thedamper 130. For firmer joining, thehinge shaft 122 may be rotatably inserted in thedoor 20 b. - The
damper 130 is configured to damp a rotation force generated when thesupplementary door 120 is opened or closed. Preferably, a damping force of thedamper 130 at the time of opening of thesupplementary door 130 is greater than a damping force of thedamper 130 at the time of closing thesupplementary door 120, because thesupplementary door 120 is opened at a high speed by gravity. Thedamper 130 may be fabricated with an elastic member for generating the damping force. That is, if thesupplementary door 120 rotates, the elastic member in thedamper 130 deforms to absorb the rotation force of thesupplementary door 120. However, such an elastic member causes permanent deformation due to repetitive deformation, failing to maintain a required damping force. Therefore, in the present invention, thedamper 130 employs oil for generating the damping force. As known, since anoil damper 130 can keep supplying a uniform damping force, theoil damper 130 is effective for damping thesupplementary door 110 that is opened/closed frequently. A preferred embodiment of theoil damper 130 will be described with reference to FIGS. 4 and 5. Besides the oil damper illustrated, different kinds of dampers known to this field of art can be applicable to the present invention. - shown, the
damper 130 includes acase 131, and arotation shaft 132 rotatably mounted in thecase 131. Thecase 131 is filled with an amount of oil ‘O’, and sealed for preventing the oil ‘O’ from leaking therefrom. Therotation shaft 132 is projected from thecase 131, partly. Therotation shaft 132 is configured to generate a friction force or a hydraulic force together with the oil ‘O’. - In more detail, referring to FIG. 5, the
rotation shaft 132 hasprojections 132 a configured to contact with the oil ‘O’ in the case directly. That is, theprojections 132 a are formed on a part of therotation shaft 132 positioned inside of thecase 131. Theprojections 132 a may be a gear or a screw formed continuously on therotation shaft 132. Since the oil ‘O’ has a certain viscosity, if therotation shaft 132 rotates, a predetermined friction force acts on theprojections 132 a in contact with the oil ‘O’. The friction force acts in a direction opposite to a rotation direction of therotation shaft 132, to give a torque in a direction opposite to the rotation direction of therotation shaft 132. Therefore, the rotation force of therotation shaft 132 is dampened by the friction force and the torque. In the meantime, as shown in FIG. 5 in dashed lines, supplementary projections may be formed on an inside circumferential surface of thecase 131 too extended between theprojections 132 a. A closed channel is formed betweenadjacent projection 132 a and the supplementary projection, to dampen the rotation force of the rotation shaft by using a hydraulic pressure in the channel. Moreover, by forming different sizes of channels depending on the rotation direction of therotation shaft 132, different damping forces are obtainable. Alikely, by changing friction surfaces of theprojections 132 depending on the rotation direction of therotation shaft 132, different damping forces are obtainable. - the
oil damper 130, thecase 131 is fixed to thedoor 20 b, and therotation shaft 132 is fixed to thesupplementary door 120. If thesupplementary door 120 had thehinge shaft 122, therotation shaft 132 is joined with thehinge shaft 122. Accordingly, in opening and closing thesupplementary door 120, therotation shaft 132 rotates relative to thecase 131 together with thesupplementary door 120, while therotation shaft 132 dampens the rotation force of thesupplementary door 120. - The operation of the supplementary storage device for a refrigerator of the present invention will be described with reference to the attached drawings.
- For using the
supplementary storage device 100, at first, the user opens thedoor 120. In more detail, when the user pulls thehand grip 120 a (see FIG. 2), thehook 121 is released from theholder 111, and, then, thedoor 120 rotates downwardly around the bottom edge thereof by gravity. During the rotation, thesupplementary door 120 rotates slowly owing to the damping force of thedamper 130, enough to give no impacts to thedoor 20 b, thedamper 130, and the supplementary door itself when thesupplementary door 120 is rotated, fully. Once theopening 110 is opened fully by rotation of thedoor 120, the user puts food into the refrigerator, or takes out food from the refrigerator. Or, the user may take out, and set food on therear surface 120 b of thesupplementary door 120 for eating. - Thereafter, alikely, if the user rotates the supplementary door upwardly, the
supplementary door 120 rotates slowly by thedamper 130. At the end, thehook 121 is engaged with theholder 111, such that thesupplementary door 120 is closed fully to shut off theopening 110. - As has been described, the use of the
damper 130 in thesupplementary storage device 100 of the present invention permits damping of a rotation force of thesupplementary door 120, to drop an opening speed of thesupplementary door 120, significantly. The damping action minimizes impact, vibration, and noise caused by thesupplementary storage device 100, and minimizes damage to different components of thesupplementary storage device 100. According to this, lifetime and stability of thesupplementary storage device 100 are increased, and reliability and satisfaction of the user for the supplementary storage device are increased. - It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
