Description

GASKET FILLER GUIDE APPARATUS FOR REFRIGERATOR

Technical Field

[1] The present invention relates to a two-door type refrigerator, and more particularly, to a gasket filler guide apparatus for a refrigerator, in which a filler for bringing a gasket into close contact is provided at the inside of a door so that the filler moves along the opening door.

Background Art

[2] FIGS. 1 and 2 are a schematic plan view of a refrigerator having a conventional filler installing structure, where FlG. 1 shows a state where a door is closed and FlG. 2 shows a state where a door is opened.

[3] The refrigerator shown in the figures, which is a French door type refrigerator, has two doors 1 connected with a hinge 3 in a refrigerator body 2 having no partition wall at the inside thereof, has a gasket for preventing cool air from being leaked even in a portion where two doors 1 meet each other, and a filler 4 provided in one door so that the gasket brings into close contact with each other in a state where the door is closed.

[4] Therefore, as shown in FlG. 1, in a state where both doors 1 are closed, the gasket of the door comes in close contact with the filler 4 to seal the inside of the refrigerator and as shown in FlG. 2, when the door, which is provided with the filler 4, is opened, the filler 4 is moved along the door and when the door, which is not provided with the filler 4, is opened, the filler 4 is just disposed in the refrigerator body 2.

[5] However, as shown in FlG. 2, in a refrigerator having such a conventional filler installing structure, there is a problem that when the door 1, which is provided with the filler 4, is again closed after opening, the filler 4 is bumped into an opposing door.

[6] Further, when the door 1 is opened, there is a problem that the filler 4 is always exposed and thus an outer appearance of the door gives a complicated impression, so that a fine view of the refrigerator is deteriorated.

[7] On the other hand, FIGS. 3 to 5 are drawings of a refrigerator disclosed in Japanese

Patent Application Laid-open No. 2000 - 62032, where FlG. 3 is a view schematically illustrating the front of a refrigerator provided with a conventional gasket filler guide apparatus for a refrigerator, FlG. 4 is a cross-sectional view illustrating a major part thereof when a door of a refrigerator provided with the conventional gasket filler guide apparatus is closed, and FlG. 5 is a cross-sectional view illustrating the major part thereof when the door of a refrigerator provided with the conventional gasket filler guide apparatus is opened.

[8] As shown in the figures, a fourfold body, i.e. a filler 15 is provided between both doors 10 connected to a refrigerator body 12 with a hinge 13 and gaskets 16 for bringing into close contact with the filler 15 are provided in side surfaces of both doors

10, respectively. [9] Guide grooves 15a are formed at the top and the bottom of the filler 15 and support arms 18, which are inserted into the guide grooves 15a, are provided at the upper side and the lower side of the door 10, respectively. [10] As shown in FlG. 4, in such a conventional refrigerator, in a state where both doors

10 are completely closed, both gaskets 16 come in close contact with the filler 15 to seal the inside of the refrigerator. [11] As shown in FlG. 5, when a user catches and pulls one side of the filler 15, the support arm 18 of the opposing door 10 is separated from the filler 15 along the guide groove 15a and the filler 15 moves along the opening door. [12] Therefore, in the conventional refrigerator, although any one of the doors 10 is opened, the filler 15 is opened or closed along opening of the door. [13] However, in a state where the filler 15 is positioned between the doors 10, because the conventional gasket filler guide apparatus is composed to be moved along the opening door, there is a problem that the filler 15 is exposed to the outside between the doors, so that a fine view of a refrigerator is deteriorated. [14] Furthermore, as shown in FlG. 5, there is a problem that because the filler 15 is directly caught and opened, the filler 15 may be separated from the door and easily out of order, due to its repeated use. [15] Furthermore, in a state where the door 10 is opened, because the filler 15 is exposed to the outside, a mounting state of the filler 15 is not stable, a fine view thereof is deteriorated, and its portion, which comes in contact with a user's hand so that a user can easily pull the filler 15, has a pointed shape, so that there is a problem that a user may be hurt by the filler upon opening the door.

Best Mode for Carrying Out the Invention [47] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. [48] For reference, the present invention can be applied to even a refrigerator which has two doors, but which has only one of a freezing chamber and a chilling chamber, and can be also applied to a refrigerator in which both doors are opened in a vertical direction as well as a refrigerator in which both doors are opened in a lateral direction.

Therefore, the present invention can be applied to a refrigerator having a side gasket assembly for sealing a gap between doors by coming in close contact with an opposing door in a portion where both doors face each other. [49] Embodiments of the present invention will be described about a French type refrig erator having one chilling chamber and two doors which can be opened in a lateral direction. [50] FlG. 6 is a front view of a refrigerator provided with a gasket filler guide apparatus according to the present invention. [51] In the refrigerator shown in the figure, a freezing chamber 31 is positioned in the lower side and a chilling chamber 32, which is provided with two doors 35, is positioned in the upper side. [52] Gaskets (not shown), which prevents cold air of the refrigerator from leaking to the outside by coming in close contact with the refrigerator body (not shown) in both doors

35L and 35R, are provided in the vertical and lateral directions of the doors 35L and

35R. [53] Specifically, a partition wall does not exist in a portion in which both doors 35L and

35R face each other, so that a floating filler 50, which can seal a gap between the doors by bringing the gasket into close contact, is provided in the portion. [54] The floating filler 50 is composed to move along the opening door and provide in the rear of the door by rotating to the inside of the door in a state where the door is opened. [55] A detailed construction of such a floating filler 50 and means for guiding the filler will be described in detail in the following embodiments. [56] FIGS. 7 to 10 are views illustrating a gasket filler guide apparatus for a refrigerator according to a first embodiment of the present invention, where FlG. 7 is an exploded perspective view of a side portion of the door, FlG. 8 is a plan view illustrating a major part of the gasket filler guide apparatus for a refrigerator, FlG. 9 is a view illustrating the opening order of a left door, and FlG. 10 is a view illustrating the opening order of a right door. [57] As shown in the figures, the gasket 38 for sealing the refrigerator is provided in both doors 35 and a side gasket 39 for sealing doors is provided in the side of the door

35. [58] A filler safe-arriving unit 36, which has the rear entered more inwardly than the front so that the floating filler 50 may be arrived safe by rotating upon opening the door, is formed in the inside of the door 35. [59] Such a filler safe-arriving unit 36 is a rear portion of the door 35 to be inserted into the refrigerator and is generally provided with a reception container 37, etc. to store food such as a bottle or a can. [60] The floating filler 50 is formed long to fit to a vertical length of the door 35 and the filler safe-arriving device 60, which is expanded so that both gaskets 39 come in close contact with each other upon closing the door and which arrives safe at the inside of the opening door upon opening the door and comes out along the door, is provided in the top and the bottom thereof. [61] The filler safe-arriving device 60 includes filler holders 61 and 65 provided in the filler safe-arriving units 36 of the both doors 35 so that the floating filler 50 may be arrived safe and filler guides 55 and 70 for moving the floating filler 50 depending on relative movement between the floating filler 50 and the refrigerator body 40 when the door 35 is opened or closed. [62] Interference avoidance groove 51 for avoiding interference with the filler holders 61 and 65 is formed in the rear of the floating filler 50 and a pair of bosses 52, which are coupled to the filler holders 61 and 65, are formed in the interference avoidance groove

51. The front of the interference avoidance groove 51 has a closed structure for coming in contact with both gaskets 39. [63] A pair of filler holders 61 and 65 are disposed in the filler safe-arriving unit 36 of each door 35 in the front-rear direction to couple to a pair of bosses 53 and 54, where a leading holder 61, which is positioned in the front, is opened in a direction in which the doors 35 face each other and the safe-arriving holder 65, which is positioned in the rear, has a structure opened toward the refrigerator body 40. [64] The leading holder 61 has a U shaped groove 61a so that bosses 53 and 54 of both floating fillers 50 may be detached in an opposite direction. [65] The safe-arriving holder 65 has an elastic plate spring structure and has a semicircle groove 65a so that bosses 53 and 54 of the floating filler 50 may be inserted and arrived safe. [66] The filler guide includes a cam block 70 which is provided in the inner top or the inner bottom of the refrigerator body 40 and in which a cam hole 71 is formed to guide movement of the floating filler 50 and a cam protrusion 55 which is protruded from the upper or the bottom of the floating filler 50 to be inserted into the cam hole 71.

[67] The cam hole 71 is formed to have a path dividing from the refrigerator body 40 to the outside. That is, because the cam hole 71 is formed in a V shaped structure, the cam hole 71 is guided so that the floating filler 50 is positioned to the filler safe- arriving unit 36 while rotating along the cam hole 71 upon opening the door and so that the floating filler 50 is expanded between both doors upon closing the door 35.

[68] In the cam hole 71, a vertex 71a for guiding lateral movement of the cam protrusion

55 is pointedly formed at the start portion thereof.

[69] An operation of a gasket filler guide apparatus for a refrigerator according to the first embodiment of the present invention having the above-mentioned construction will be described.

[70] Referring to FlG. 9, in a state where the doors 35L and 35R are closed as in A of

FlG. 9, two bosses 53 and 54 of the floating filler 50 are inserted into the leading holders 61 of both doors 35L and 35R, respectively and the floating filler 50 is positioned in the rear of both doors 35L and 35R.

[71] Therefore, the gasket 39 of both doors 35L and 35R comes in close contact with a front surface of the floating filler 50 and seals both doors.

[72] In a such state, when the left door 35L opens as in (B) and (C) of FlG. 9, the floating filler 50 moves to the front while disposing to be oblique along the left door 35L by the leading holder 61 of the left door 35L side and at the same time, the cam protrusion 55 of the floating filler 50 moves along a left path from the vertex 71a of the cam hole 71 formed in the cam block 70.

[73] At this time, the boss 54 of the floating filler 50, which is positioned in the right, begins to separate from the leading holder 61 of the right door 35R side.

[74] Thereafter, when the left door 35L is opened further, the floating filler 50 continues to move along the left door 35L as in (D) of FlG. 9, the cam protrusion 55 moves along the cam hole 71, and the floating filler 50 rotates toward the left door 35L from the boss 53 inserted into the leading holder 61.

[75] Thereafter, when the door 35 is opened further, as in (E) of FIG. 9, the cam protrusion 55 of the floating filler 50 comes out from the cam hole 71 and at the same time, the rear boss 54 is inserted into and arrived safe in the safe-arriving holder 65, and the floating filler 50 is positioned to the filler safe-arriving unit 36 of the door 35.

[76] In such a state, when the floating filler 50 comes in contact with a side surface of the inside of the door 35L as in (F) and (G) of FlG. 9, the left door 35L is opened and thus the floating filler 50 is not protruded to the outside of the door 35L.

[77] On the other hand, the opened door 35L is closed in the reverse order shown in FlG. 9. That is, the door 35L is closed in the order of (G), (F), and (E) of HG. 9 and in a state where the door 35L is almost closed as in (D), the cam protrusion 55 of the floating filler 50 is advanced into the cam hole 71 of the cam block 70. Thereafter, because the cam protrusion 55 moves along the cam hole 71, the floating filler 50 rotates again to the right door 35R as in processes of (C) and (B) of FIG. 9 while it is separated from the safe-arriving holder 65. Thereafter, when the door 35L is completely closed, as in (A) of FIG. 9, the gaskets 39 of both doors 35 comes in close contact with the doors and seal the inside of the refrigerator.

[78] Next, to the contrary as described above, when the right door 35R is opened as shown in FIG. 10, as described when the left door 35L opens as shown in FIG. 9, the floating filler 50 is arrived safe on the side surface of the inside of the right door 35R while moving along the right door 35R. When the right door 35R is closed, the operations are progressed in the reverse order of the above order.

[79] Therefore, as described above, in a gasket filler guide apparatus for a refrigerator according to the present invention, the floating filler 50 comes in close contact with the inside of the door 35 while moving along the opening door 35 although any one of doors 35 is opened and both gaskets 39 comes in close contact with the doors while the floating filler 50 is automatically expanded when the door 35 is closed.

[80] On the other hand, in the present embodiment, because the vertex 71a is formed in the center of the cam hole 71 of the cam block 70, the cam protrusion 55 of the floating filler 50 is instantaneously arrived safe in one door while rotating along any one side of the cam hole 71 from the vertex 71a although both doors 35L and 35R are simultaneously opened, so that the floating filler 50 maintains a safe-arriving state even when both doors 35L and 35R are simultaneously opened.

[81] Below, the second embodiment according to the present invention will be described. For reference, elements identical or similar with those of the first embodiment are denoted by like reference numerals and thus descriptions thereof will be omitted.

[82] FIGS. 11 to 15 are views illustrating a gasket filler guide apparatus for a refrigerator according to a second embodiment of the present invention, where FIG. 11 is an exploded perspective view thereof, FIG. 12 is a plan view illustrating a major part of the gasket filler guide apparatus, FIG. 13 is a view illustrating the opening order of a left door, FIG. 14 is a view illustrating the closing order of the left door, and FIG. 15 is a view illustrating the opening order of a right door.

[83] A construction of the second embodiment of the present invention is similar with that of the first embodiment, but a construction of a cam protrusion 155 formed in the floating filler 50 and a cam block 170 provided in the refrigerator body is different from that of the first embodiment. [84] That is, the cam block 170 is provided in the top surface or the bottom surface of the inside of the refrigerator body 40 and a cam hole 171, which consists of a streamlined cam surface with which the cam protrusion 155 comes in contact when the door 35 is opened or closed, is formed on the front surface thereof.

[85] The cam hole 171 is formed laterally long and generally serves to guide the floating filler 50 so that the floating filler 50 may rotate in a direction of the opposite door 35 when the opened door 35 is closed.

[86] The cam protrusion 155 is formed on the top surface or the bottom surface of the floating filler 50, has a streamlined structure formed laterally long, and both ends thereof move while coming in contact with the cam hole 171.

[87] An operation of the second embodiment of the present invention will be described with reference to HGS. 13 to 15.

[88] First, referring to FIG. 13, in a state where doors 35L and 35R are closed as in (A) of FIG. 13, two bosses 53 and 54 of the floating filler 50 are inserted into the leading holders 61 of both doors 35L and 35R, respectively and the floating filler 50 is positioned in the rear of both doors 35L and 35R. Therefore, the gasket 39 of both doors 35L and 35R comes in close contact with a front surface of the floating filler 50 and seals both doors.

[89] In a such state, when the left door 35L opens as in (B) of FIG. 13, the floating filler

50 moves along the left door 35L by the leading holder 61 of the left door 35L side. At this time, as the front of the floating filler 50 is engaged with the gasket 39 of the opposing door 35R, it rotates in a direction of the left door 35L while moving inclined.

[90] The boss 54 of the floating filler 50, which is positioned in the right, begins to separate from the leading holder 61 of the right door 35R side.

[91] Thereafter, when the left door 35L is opened further, the floating filler 50 is engaged with the gasket 39 of the right door 35R while keeping moving along the left door 35L as in (C) of FIG. 13, whereby the floating filler 50 rotates toward the left door 35L from the boss 53 inserted into the leading holder 61 and at this time, the cam protrusion 155 moves along the side surface of the inside of the cam hole 171.

[92] Thereafter, when the door 35L is opened further, as in (D) of FIG. 13, as the rear boss 54 is inserted into and arrived safe in the safe-arriving holder 65 of the left door 35L, the floating filler 50 is positioned to the filler safe-arriving unit 36 of the left door 35L.

[93] In a state where the floating filler 50 comes in contact with a side surface of the inside of the door 35L, the left door 35L is opened and thus the floating filler 50 is not protruded to the outside of the door.

[94] On the other hand, when the opened door 35L is closed, if the door 35L is almost closed as in A of FIG. 14, the cam protrusion 155 of the floating filler 50 comes in contact with the cam hole 171 of the cam block 170. Thereafter, because the cam protrusion 155 moves to the right along the cam hole 171, the floating filler 50 rotates toward the right door 35R as in processes of (B) and (C) of FlG. 14 while it is separated from the safe-arriving holder 65.

[95] Thereafter, when the door 35L is completely closed, as in (D) of FlG. 14, the gaskets 39 of both doors 35L and 35R come in close contact with the doors and seal the inside of the refrigerator.

[96] Next, when the right door 35R is opened as shown in FlG. 15, as described when the left door 35L opens, the floating filler 50 is arrived safe on the side surface of the inside of the right door 35R while moving along the right door 35R.

[97] Therefore, as described above, in the gasket filler guide apparatus according to the second embodiment of the present invention, the floating filler 50 comes in close contact with the inside of the door 35 while moving along the opening door 35 although any one of the doors 35L and 35R is opened and both gaskets 39 can come in close contact with the doors while automatically rotating toward the closed door 35 by interaction of the cam protrusion 155 and the cam hole 171 when the door is closed.

[98]

Industrial Applicability

[99] According to a gasket filler guide apparatus for a refrigerator of the present invention, which has the above-mentioned construction and is operated as described above, because a floating filler, which is positioned in the inside of doors and in which both gaskets come in close contact, is composed to be moved along the opening door, there is an advantage that the door can be easily opened although any one of the doors is opened.

[100] Further, because the floating filler fixes its position while rotating to the inside of the door upon opening the door, the filler is not exposed to the outside upon opening the door, so that an outer appearance of the refrigerator improves and a more stable filler installation structure can be secured.
