Abstract
Description
- Example embodiments relate to a refrigerator with a door opening apparatus to allow a user to easily open a door of the refrigerator.
- In general, a refrigerator is an apparatus having a separate cooling unit chamber provided in the rear of a freezing chamber, an evaporator provided in the cooling unit chamber, and cool air generated from the evaporator provided by operation of a compressor which is forcibly supplied to the freezing chamber or a refrigerating chamber. The cool air in the freezing chamber or the refrigerating chamber is returned to the cooling unit chamber, to freeze or refrigerate the corresponding chamber to maintain freshness of food stored in the corresponding chamber for a long time.
- When a door of the freezing chamber or the refrigerating chamber is opened for a designated time and then is closed in order to put/take articles into/from the freezing chamber or the refrigerating chamber, humid and warm external air from outside of the freezing chamber or the refrigerating chamber is rapidly introduced into the freezing chamber or the refrigerating chamber.
- The external air introduced into the freezing chamber or the refrigerating chamber is rapidly cooled due to cool temperature conditions within the freezing chamber or the refrigerating chamber, and thus is reduced in volume and temporarily maintains a pressure a little lower than the external atmospheric pressure (hereinafter, referred to as "a negative pressure") for a designated time.
- Therefore, when opening the door the negative pressure is generated in the freezing chamber or the refrigerating chamber, and the door may be difficult to open without forcibly removing the negative pressure.
- Particularly, a French-type refrigerator, may have a refrigerating chamber and a freezing chamber disposed vertically, may have a pair of hinge-type doors provided on the upper refrigerating chamber and a drawer-type door may be provided on the lower freezing chamber which has a larger width than the refrigerating chamber and the freezing chamber and also has a larger size than a general refrigerator. This may cause greater difficulty when opening of the freezing chamber due to weight of the door, magnetic force of a gasket at the edge of the rear surface of the door, weights of articles stored on racks, and a pressure difference between the inside and the outside of the lower freezing chamber.

The French-type refrigerator may have a relatively larger width to store wide articles, such as pizza, as compared with a side by side refrigerator, a general BMF refrigerator, and a top mounted freezer (TMF) refrigerator. - Although example embodiments describe a structure of the refrigerator including three divided storage chambers, the refrigerator may include only two divided storage chambers, i.e., an upper storage chamber and a lower storage chamber.
-
Racks 21 to receive food to be stored in a refrigerated state may be installed in the upper storage chamber 20 and separated from each other by a designated interval, andreceipt drawers doors variable chamber 30 and thelower storage chamber 40. - A pair of
doors - The
doors variable chamber 30 and thelower storage chamber 40 may be respectively provided in front of thevariable chamber 30 and thelower storage chamber 40. Since thedoors variable chamber 30 and thelower storage chamber 40, when thedoors receipt drawers doors - Since each of the
variable chamber 30 and thelower storage chamber 40 may have thesingle door door variable chamber 30 and thelower storage chamber 40 because of magnetic force of a gasket 75 (with reference toFIG. 3 ) at the edge of the rear surface of thedoor door receipt drawer receipt drawer 61 of 71, and a pressure difference between the inside and outside of thevariable chamber 60 or thelower storage chamber 70. - In order to solve the above problem, the refrigerator in accordance with the example embodiments may include a door opening apparatus to easily open the
door variable chamber 30 or thelower storage chamber 40. - The door opening apparatus may be provided on each of the
variable chamber 30 and thelower storage chamber 40, or may be provided on any one of thevariable chamber 30 and thelower storage chamber 40 as needed. - The door opening apparatuses respectively provided on the
variable chamber 30 and thelower storage chamber 40 may have the same structure. Therefore, only the door opening apparatus provided on thelower storage chamber 40 will be described hereinafter, and a description of the door opening apparatus provided on thevariable chamber 30 will be omitted. - As shown in
FIGS. 2 to 4 , the refrigerator in accordance with the example embodiments may include thesecond door 70 to open and close thelower storage chamber 40 in a sliding manner, ahandle unit 80 on the upper portion of thesecond door 70 in the horizontal direction movable forward and backward, pushmembers 90 rectilinearly moving in a direction of the rear surface of thesecond door 70 in connection with the forward movement of thehandle unit 80, andinterlocking units 100 provided between thehandle unit 80 and thepush members 90 to transmit moving force of thehandle unit 80 to thepush members 90. - The
receipt drawer 71 to receive articles to be stored may be formed integrally with the rear surface of thesecond door 70 to slide according to the forward and backward movement of thesecond door 70, and thegasket 75 in which amagnet 75a is received may be disposed along the edge of the rear surface of thesecond door 70 to prevent leakage of cool air from thelower storage chamber 40 and to improve hermetic sealing of thelower storage chamber 40. - Sliding
rails 41 to guide smooth sliding of thesecond door 70 may be provided on both side surfaces of thereceipt drawer 71. - A
front panel 72 forming the external appearance of thesecond door 70 may be mounted on the front surface of thesecond door 70, and adoor cap 73 may be mounted on the upper surface of thesecond door 70. - The
front panel 72 may provide an aesthetically pleasing external appearance of thesecond door 70, and may be made of tempered glass, resin, and metal. In the example embodiments, thefront panel 72 may be made of a metal plate. -
Receipt parts 73a to mount the respective components of the door opening apparatus, such as thehandle unit 80, the interlockingunits 100, and thepush members 90, and guideparts 73b to guide forward and backward sliding of slidingconnection parts 82, which will be described later, may be formed on thedoor cap 73. - The
front panel 72 may be provided with openings having a size corresponding to theguide parts 73b. The slidingconnection parts 82 of thehandle unit 80 are received in theguide parts 73b through the openings, and may be mounted to be slidable forward and backward. - The
handle unit 80 may be mounted on the upper portion of the front surface of thesecond door 70 allowing a user to easily grip thehandle unit 80 to move thesecond door 70 forward and backward. - The
handle unit 80 may include agrip part 81 gripped by a user, a pair of slidingconnection parts 82 provided at both ends of thegrip part 81 and connected to thesecond door 70 to be slidable forward and backward, andpressure parts 83 connected to the rear surfaces of the slidingconnection parts 82 to transmit force to the interlockingunits 100. - The
handle unit 80 may be substantially parallel and disposed on the upper edge of thesecond door 70. - The
grip part 81 may be formed at a width which is substantially equal to the width of thesecond door 70 or may be smaller than the width of thesecond door 70 by a designated length, thereby allowing a user to grasp a wide area of thegrip part 81. - The sliding
connection parts 82 may protrude from both ends of thegrip part 81 in a direction of thesecond door 70, and connect thehandle unit 80 to thesecond door 70 so that thehandle unit 80 may be slidably moved forward and backward relative to thesecond door 70. - The
guide parts 73b opened forward corresponding to the slidingconnection parts 82 may be formed on thesecond door 70. Theguide parts 73b receive the slidingconnection parts 82, and guide sliding movement of the slidingconnection parts 82. In example embodiments, theguide parts 73b may be formed on thedoor cap 73 of thesecond door 70. - The
pressure parts 83 may move forward and backward according to the forward and backward sliding movement of the slidingconnection parts 82. Each of thepressure parts 83 may include aconnection plane 83a screw-connected to the slidingconnection part 82, abent plane 83b bent forward from theconnection plane 83a and extended, and anopening 83c formed on thebent plane 83b to receive a front end of a firstrotating part 103 of the interlockingunit 100, which will be described later. - The first
rotating part 103 may be mounted and inserted into thepressure part 83. Therefore, when a user grasps thegrip part 81 and pulls thehandle part 80 forward, the slidingconnection parts 82 slide forward along theguide parts 73b, and the firstrotating parts 103 may be inserted into theopenings 83c of thepressure parts 83 which may be pressurized by movement of thepressure parts 83, thereby rotating the interlockingunits 100. - Each of the interlocking
units 100 may include arotary shaft 101. The firstrotating part 103 may be extended from one end of therotary shaft 101 and connected to thepressure part 83, and a secondrotating part 105 may be extended from the other end of therotary shaft 101 opposite to the firstrotating part 103 and connected to thepush member 90. - The first
rotating part 103 of the interlockingunit 100 may be connected to thepressure part 83, and when a user grasps thegrip part 81 and pulls thehandle unit 80 forward, thepressure part 83 may rotate the interlockingunit 100 and cause thepush member 90 connected to the secondrotating part 105 to slide forward in a direction of thelower storage chamber 40. - The end of the first
rotating part 103 may be bent downward and inserted into theopening 83c of thepressure part 83. - When the
pressure part 83 moves forward, thepressure part 83 and the firstrotating part 103 reciprocally slidably contact each other to rotate the interlockingunit 100 according to forward and backward movement of thepressure part 83, and the firstrotating part 103 slides relative to thepressure part 83 and is rotated. - The interlocking
unit 100 further includes anelastic member 107 to return thehandle unit 80 to its original position when external force is removed. - For example, the
elastic member 107 may be provided in the shape of a coil spring and be connected to therotary shaft 101, as shown inFIG. 2 . - One end of the
coil spring 107 may be fixed to one end of thereceipt part 73a of thedoor cap 73, and the other end of theelastic member 107 may be fixed to the interlockingunit 100. Thus, thecoil spring 107 may provide elastic force to pressurize the interlockingunit 100 in a direction A. - Therefore, when a user grasps the
grip part 81 and pulls thehandle unit 80 forward, the interlockingunits 100 may be rotated in a direction B by thepressure parts 83 and the elastic member107 may be elastically compressed. When the user releases thegrip part 81, i.e., when external force applied to thehandle unit 80 is removed, the interlockingunits 100 may be rotated in the direction A by restoring force of theelastic member 107, and thegrip part 81 slides backward, thereby returning thehandle unit 80 to its original position. - A receipt groove (not shown) corresponding to the
rotary shaft 101 may be formed on thereceipt part 73a of thedoor cap 73, andseparation prevention pieces 109 surrounding therotary shaft 101 to firmly fix therotary shaft 101 may be connected to the receipt groove. - The
push members 90 are slidably provided on the upper surface of thesecond door 70, and serve to pressurize the edge of themain body 10, i.e., the front surface of the second insulatingdiaphragm 12 to separate thesecond door 70 from themain body 10. - An arc-shaped
first contact part 91 corresponding to the secondrotating part 105 is formed at one end of thepush member 90, and asecond contact part 93 to transmit the pressurizing force of thepressure part 83 to themain body 10 may be formed at the other end of thepush member 90. -
Slots 73c are formed on the upper surface of thesecond door 70, for example, on thedoor cap 73, to slidably move thepush members 90. - The
receipt parts 73a exposed to the outside to obtain working spaces to assemble thehandle unit 80, the interlockingunits 100, and thepush members 90 with the upper surface of thesecond door 70 may be formed on thedoor cap 73, and covers 110 to cover assembly portions of thepush members 90, theelastic member 107, and thehandle unit 80 may be mounted on thedoor cap 73. - In the example embodiments, the
handle unit 80 only moves forward and backward and only regions of thefront panel 72 corresponding to the slidingconnection parts 82 may be opened. Front surface regions of thesecond door 70 except for the slidingconnection parts 82 may be covered with onefront panel 72. Therefore, connection portions of the front surface of thedoor 70 exposed to the user with a different material may be minimized, thereby improving the aesthetically pleasing external appearance of thedoor 70. - Next, an assembly procedure of the handle unit of the refrigerator in accordance with example embodiments will be described.
- The
door cap 73 provided with thereceipt parts 73a to receive the respective components may be connected to the front surface of thesecond door 70, and thepush members 90 connected to the interlockingunits 100 may be mounted on thereceipt parts 73a of thedoor cap 73. Thesecond contact parts 93 of thepush members 90 may protrude from the rear surface of thesecond door 70 through theslots 73c. - Thereafter, the
handle unit 80 connected with thepressure parts 83 may slide and connect to receipt spaces through theguide parts 73b, and the interlockingunits 100 may be rotatably fixed to thereceipt parts 73a using theseparation prevention pieces 109. - Thereafter, the
covers 110 may be mounted on thedoor cap 73, completing installation of the door opening apparatus on thedoor 70. - Next, operation of the refrigerator in accordance with example embodiments will be described with reference to
FIGS. 3 and4 . - If the
lower storage chamber 40 of the refrigerator in accordance with example embodiments is opened, when thegrip part 81 is moved forward, the slidingconnection parts 82 may slide forward and thepressure parts 83 connected to the slidingconnection parts 82 may pressurize the firstrotating parts 103, thereby rotating the interlockingunits 100 in the direction B. When the interlockingunits 100 are rotated in the direction B, the secondrotating parts 105 may pressurize thepush members 90, and thepressurized push members 90 may rectilinearly move and pressurize the upper edge of thelower storage chamber 40, i.e., the front surface of the second insulatingdiaphragm 12. - The
second door 70 is separated from themain body 10 by a designated distance because of the above pressurizing force. Then, pressure equilibrium between the inside and the outside of thelower storage chamber 40 may be achieved and by weakening connecting force of thesecond door 70 with themain body 10 because of magnetic force of thegasket 75, thereby enabling thesecond door 70 to be easily slidably opened. - Therefore, if the
second door 70 of thelower storage chamber 40 having a heavy weight is opened, a user may allow a pair of thepush members 90 to pressurize themain body 10 through movement only in one direction, i.e., grasping and moving of thegrip part 81 forwards, thereby easily opening thesecond door 70 with small or minimal movement and force. - Thereafter, when the user releases the
grip part 81 and external force applied to thehandle unit 80 is removed, the interlockingunits 100 may be rotated in the direction A by theelastic members 107 connected to the interlockingunits 100. When the firstrotating parts 103 are rotated by the rotation of the interlockingunits 100, thepressure parts 83 connected to the firstrotating parts 103 may rectilinearly move backward according to the rotation of the firstrotating parts 103. The slidingconnection parts 82 connected to thepressure parts 83 and thegrip part 81 connected to the slidingconnection parts 82 may slide toward thesecond door 70, and are returned to their initial state. - Simultaneously, the
push members 90 may slide backward according to the rotation of the interlockingunits 100, and are returned to their initial state. - Next, a refrigerator in accordance with example embodiments will be described.
- Some parts, which are substantially the same as those in the example embodiments described with reference to
FIGS. 1 to 4 , are denoted by the same reference numerals even though they are depicted in different drawings, and a detailed description thereof will thus be omitted because it is considered to be unnecessary. -
FIG. 5 is an exploded perspective view illustrating a door and a handle unit of the refrigerator in accordance with example embodiments, andFIGS. 6 and7 are views illustrating an operating state of the door of the refrigerator in accordance with example embodiments. - As shown in
FIGS. 5 to 7 , the refrigerator in accordance with example embodiments may include asecond door 70 to open and close alower storage chamber 40 in a sliding manner, ahandle unit 80 disposed on the upper portion of thesecond door 70 in the horizontal direction movable forward and backward, pushmembers 190 rectilinearly moving in a direction of the rear surface of thesecond door 70 in connection with the forward movement of thehandle unit 80, and interlockingunits 200 provided between thehandle unit 80 and thepush members 190 to transmit moving force of thehandle unit 80 to thepush members 190. - A
door cap 73 may includereceipt parts 73a, each receiving respective components of a door opening apparatus, such as thehandle unit 80, the interlockingunit 200 and thepush member 190, and guideparts 73b to guide forward and backward sliding of slidingconnection parts 82, which will be described later. -
Pressure parts 183 of thehandle unit 80 may be screw-connected to the slidingconnection parts 82. Each of thepressure parts 183 may include afirst connection plane 183a connected to the slidingconnection part 82, anextension plane 183b bent perpendicularly from thefirst connection plane 183a, and asecond connection plane 183c bent perpendicularly forward from theexpansion plane 183b. - Therefore, the
pressure parts 183 may move forward and backward according to operation of thehandle unit 80. - The interlocking
units 200 may serve to transmit moving force of thepressure parts 183 to thepush members 190, and are provided in the shape of link members. - The refrigerator in accordance with example embodiments may further include
base parts 120 to fix the interlockingunits 200 to thereceipt parts 73a. - The
base parts 120 may be fixed to thereceipt parts 73a of thedoor cap 73. Each of thebase parts 120 may be provided with arotary shaft 121 protruding upwardly, and aslot 123 formed at a position separated from therotary shaft 121 to delimit a forward and backward moving distance of thepush member 190. - The interlocking
unit 200 may be connected to therotary shaft 121 at a middle portion thereof, and one end of the interlockingunit 200 may be rotatably link-connected to thesecond connection plane 183c and the other end of the interlockingunit 200 may be link-connected to thepush member 190. - Further, the interlocking
unit 200 may include anelastic member 207 to return thehandle unit 80 to its original position when external force is removed. - For example, the
elastic member 207 may be provided in the shape of a coil spring and be connected to therotary shaft 121. - One end of the
elastic member 207 may be fixed to thebase part 120 and the other end of theelastic member 207 may be fixed to the interlockingunit 200. Theelastic member 207 may provide elastic force to pressurize the interlockingunit 200 in a direction C. - Therefore, when a user grasps the
grip part 81 and pulls thehandle unit 80 forward, the interlockingunits 200 may be rotated in a direction D by thepressure parts 183 and theelastic member 207 may be elastically compressed. When the user releases thegrip part 81, i.e., when external force applied to thehandle unit 80 is removed, the interlockingunits 200 may be rotated in the direction C by restoring force of the elastic member207, and thegrip part 81 may slides backward, thereby returning thehandle unit 80 to its original state. - The
push members 190 may be slidably provided on the upper surface of thesecond door 70, and serve to pressurize the edge of themain body 10, i.e., the front surface of the second insulatingdiaphragm 12 to separate thesecond door 70 from themain body 10. - A
first contact part 191 connected with the other end of the interlockingunit 200 may be formed at one end of thepush member 190, and asecond contact part 192 to transmit rotating force of the interlockingunit 200 to themain body 10 may be formed at the other end of thepush member 190. -
Slots 73c may be formed on the upper surface of thesecond door 70, for example, on thedoor cap 73 to slidably move thepush member 190, in the same manner as the example embodiments shown inFIGS. 1 to 4 . - In the same manner as the example embodiments shown in
FIGS. 1 to 4 , thehandle unit 80 only moves forward and backward, and only regions of thefront panel 72 corresponding to the slidingconnection parts 82 are opened and front surface regions of thesecond door 70 except for the slidingconnection parts 82 are covered with onefront panel 72. Therefore, connection portions of the front surface of thedoor 70 exposed to the user with a different material may be minimized, thereby improving the aesthetically pleasing external appearance of thedoor 70. - Next, operation of the refrigerator in accordance with example embodiments will be described with reference to
FIGS. 6 and7 . - If the
lower storage chamber 40 of the refrigerator in accordance with example embodiments is opened, when thegrip part 81 is moved forward, the slidingconnection parts 82 may slide forward in theguide parts 73b and thepressure parts 183 connected to the slidingconnection parts 82 pull ends of the interlockingunits 200, thereby rotating the interlockingunits 200 in the direction D. When the interlockingunits 200 are rotated in the direction D, thepush members 190 connected to the other ends of the interlockingunits 200 may move along theslots 73c and rectilinearly move toward the upper edge of thelower storage chamber 40, i.e., the front surface of the second insulatingdiaphragm 12, thereby pressurizing the second insulatingdiaphragm 12. - The
second door 70 may be separated from themain body 10 by a designated distance because of the above pressurizing force. Then, pressure equilibrium between the inside and the outside of thelower storage chamber 40 may be achieved weakening connecting force of thesecond door 70 with themain body 10 due to magnetic force of thegasket 75, thereby enabling thesecond door 70 to be easily slidably opened. - Therefore, if the
second door 70 of thelower storage chamber 40 having a heavy weight is opened, a user may allow a pair of thepush members 190 to pressurize themain body 10 through movement only in one direction, i.e., grasping and moving of thegrip part 81 forward, in the same manner as example embodiments shown inFIGS. 1 to 4 , thereby easily opening thesecond door 70 with small or minimal movement and force. - Thereafter, when the user releases the
grip part 81 and external force applied to thehandle unit 80 is removed, the interlockingunits 200 may be rotated in the direction C by theelastic member 207. When the interlockingunits 200 are rotated, thepush members 190 are pulled and returned to their initial positions, and thepressure parts 183 are pulled in the opposite direction and the slidingconnection parts 82 connected to thepressure parts 183 and thegrip part 81 connected to the slidingconnection parts 82 may slide toward thesecond door 70, and are returned to their initial state. - As is apparent from the above description, a refrigerator in accordance with example embodiments may cause a handle unit to move forward move push members backward, thereby reducing malfunction of a door, and which may be easily opened even when used over a long period of time.
- Further, the refrigerator in accordance with example embodiments may include a plurality of push members operated through only forward movement of the handle unit, thereby allowing smooth opening and closing of the heavy-weight door with simple operation and small or minimal force.
- Moreover, in the refrigerator in accordance with example embodiments, the handle unit only moves forwards and backward, and only regions of a front panel corresponding to sliding connection parts may be opened and front surface regions of the door except for the sliding connection parts may be covered with one front panel.
