Abstract

The present invention relates to a refrigerator and, more specifically, to a refrigerator comprising: a main body having a refrigerator compartment and a freezer compartment formed therein; an ice making compartment delimited as a separate thermal insulation space inside the refrigerator compartment, the ice making compartment having an ice maker and an ice storage bucket; and a door for opening/closing at least a part of the refrigerator compartment, the door having a dispenser installed thereon such that same communicates with the ice making compartment. The ice making compartment has an ice discharge port formed therein. The dispenser comprises: an ice transfer duct configured to communicate with the ice discharge port when the door is closed; and a gasket positioned on the periphery of the entrance of the ice transfer duct such that, when the door is closed, the upper end thereof contacts the periphery of the ice discharge port. The periphery of the ice outlet of the ice making compartment is formed to slope downwards as same extends from the front side toward the rear side. The upper end of the gasket is also formed to slope downwards as same extends from the front side toward the rear side. The above configuration improves the degree of sealing between the dispenser of the door and the ice storage bucket of the ice making compartment, and ensures that the door is opened/closed smoothly.

Description

    TECHNICAL FIELD
  • The present disclosure relates to a refrigerator, and more particularly to a refrigerator for improving a sealing force between a dispenser of a door and an ice storage bucket of an ice making compartment and smoothly opening and closing the door.
  • BACKGROUND ART
  • In general, a refrigerator is a home appliance for storing food in a refrigerated or frozen state in a storage compartment opened and closed by a door. The refrigerator generally includes a refrigerator compartment for storing food in a refrigerated state at a low temperature and a freezer compartment for freezing and storing food in a frozen state.
  • The refrigerator may additionally include an ice making compartment that makes and stores ice for the convenience of a user. A technology of the refrigerator provided with the ice making compartment is disclosed in patent document 1 (Korean Patent No. 10-0674573).
  • Refrigerators that have been recently released have a tendency to provide a refrigerator compartment, that is used relatively more frequently than a freezer compartment, at an upper part of a main body and to provide the freezer compartment, that is used relatively less than the refrigerator compartment, at a lower part of the main body. In particular, French door refrigerators, in which a refrigerator compartment is opened and closed by two pivot doors that are respectively hinged and coupled to the left and right sides of a main body and are arranged side by side from left to right, and a freezer compartment is opened and closed by a drawer door slidably installed, have been recently in the spotlight.
  • If the refrigerator includes an ice making compartment inside the refrigerator compartment for convenience, the ice making compartment may include an ice maker and an ice storage bucket to which ice made by the ice maker is transferred. The ice storage bucket can be taken into and out of the ice making compartment. The pivot door may be provided with a dispenser including an ice transfer duct and a gasket for sealing. Thus, when the pivot door is closed, ice stored in the ice storage bucket may be directly transferred to the ice transfer duct. Therefore, ice stored in the ice making compartment can be taken out of the refrigerator through an outlet port without opening the pivot door.
  • In the related art refrigerator, when the pivot door is closed, the gasket and an ice discharge port of the ice maker contacting each other are formed side by side in front and back, that is, so as not to incline to one side, and the gasket has a constant thickness. Hence, when the pivot door is closed, there were problems that the gasket and the ice discharge port are caught in each other, or the pivot door does not close well due to the catching, or a sealing force is reduced due to poor adhesion between the gasket and the ice storage bucket.
  • PRIOR ART DOCUMENT
    • (Patent Document 1) Korean Patent No. 10-0674573
    DISCLOSURE Technical Problem
  • An object of the present disclosure is to address the above-described and other problems. Another object of the present disclosure is to provide a refrigerator capable of smoothly opening and closing a door provided with a dispenser connected to an ice making compartment and improving a sealing force between the door and an ice storage bucket of the ice making compartment.
  • Another object of the present disclosure is to provide a refrigerator.
  • Technical Solution
  • In order to achieve the above-described and other objects, in one aspect of the present disclosure, there is provided a refrigerator comprising a main body provided with a refrigerator compartment and a freezer compartment; an ice making compartment formed in the main body as a separate thermal insulation space from the refrigerator compartment, the ice making compartment including an ice maker; and a door configured to open and close the ice making compartment and the refrigerator compartment, the door including a dispenser communicating with the ice making compartment, wherein the ice making compartment is provided with an ice discharge port from which an ice made by the ice maker is discharged, wherein the dispenser is provided with an ice transfer duct communicating with the ice discharge port, wherein a gasket is installed at a perimeter of the ice transfer duct, and an upper surface of the gasket contacts a lower surface of the ice discharge port, and wherein the lower surface of the ice discharge port and the upper surface of the gasket are formed to be inclined downward as they go from a front side to a rear side.
  • A separation distance in an up-down direction between the perimeter of the ice transfer duct and a perimeter of the ice discharge port decreases as it goes from the front side to the rear side. A thickness of the gasket positioned at the perimeter of the ice transfer duct decreases as it goes from the front side to the rear side.
  • The gasket includes a case contact portion having an upper end in close contact with a gasket contact portion and extending to an outside, a reduction portion connected to a lower end of the case contact portion and extending downwardly, and a coupling portion connected to a lower end of the reduction portion and coupled to the ice transfer duct. A thickness of the reduction portion decreases as it goes from the front side to the rear side.
  • Advantageous Effects
  • A refrigerator according to the present disclosure has the following effects.
  • The present disclosure can smoothly open and close a pivot door since a thickness of a gasket decreases as it goes to the rear side, and a gasket contact portion contacting the gasket is inclined as it goes to the rear side when the pivot door is closed.
  • The present disclosure can also improve a sealing force between a gasket and a gasket contact portion when a pivot door is closed since an upper surface of the gasket and a lower surface of the gasket contact portion are disposed to be inclined downwardly and to be opposite to each other as they go to the rear side

  • FIG. 9 a illustrates a circulation of cool air in the ice making compartment 60 by arrows.
  • Referring to FIGS. 1, 2 and 4 , a main body 10 is configured to form an appearance of a refrigerator according to an embodiment of the present disclosure. The main body 10 is formed in a rectangular parallelepiped box shape. The main body 10 includes an outer case 100, an inner case 200, a refrigerator compartment 11 provided at an upper part, a freezer compartment 12 provided at a lower side of the refrigerator compartment 11, and an ice making compartment 60 formed as an independent space.
  • The outer case 100 is configured to form an appearance of the main body 10, i.e., substantially form the appearance of the refrigerator according to an embodiment of the present disclosure. The outer case 100 is formed in a rectangular parallelepiped shape with an opened front and a space formed therein.
  • The inner case 200 is coupled to the outer case 100 by being accommodated and assembled in an inner space of the outer case 100. The inner case 200 is coupled to the outer case 100 while providing a space portion 102 between the outer case 100 and the inner case 200 so that various wires can be accommodated and a thermal insulation material 110 to be described later can be injected and foamed.
  • The inner case 200 has an opened front, and the refrigerator compartment 11 and the refrigerator compartment 11 can be selectively shielded by doors 300 and 400, respectively.
  • The refrigerator according to an embodiment of the present disclosure includes a main body 10 including a refrigerator compartment 11, a freezer compartment 12, and a special compartment 13; an ice making compartment 60 formed in the main body 10 as a separate thermal insulation space from the refrigerator compartment 11, the freezer compartment 12, and the special compartment 13, the ice making compartment 60 including an ice maker 700; and a door 310 that opens and closes the refrigerator compartment 11 and is provided with a dispenser 330 communicating with the ice making compartment 60. The ice making compartment 60 is provided with an ice discharge port 6113 from which ice made by the ice maker 700 is discharged, and the dispenser 330 is provided with an ice transfer duct 331 communicating with the ice discharge port 6113. A gasket 332 is formed along a perimeter of the ice transfer duct 331, and an upper surface of the gasket 332 contacts a lower surface of the ice discharge port 6113. The lower surface of the ice discharge port 6113 and the upper surface of the gasket 332 are formed to be inclined downward as they go from a front side to a rear side.
  • The refrigerator compartment 11 and the ice making compartment 60 are simultaneously formed as independent spaces by foaming.
  • The freezer compartment 12 may be formed as an independent space at the same time as the refrigerator compartment 11 and the ice making compartment 60 by foaming.
  • The refrigerator according to an embodiment of the present disclosure is configured such that the refrigerator compartment 11, the freezer compartment 12, and the special compartment 13 are partitioned from each other in an up-down direction by a partition wall.
  • The partition wall is provided through integral injection and foamed integrally, but may be composed of a separate thermal insulation wall and assembled.
  • In an embodiment of the present disclosure, a pivot door 300 is formed at a front surface of the refrigerator compartment 11.
  • The pivot door 300 includes a first pivot door 310 and a second pivot door 320. As a left upper end and a left lower end of the first pivot door 310 are respectively hinge-coupled to a left upper end and a left central part of the main body 10, and the first pivot door 310 pivots clockwise or counterclockwise, the first pivot door 310 opens and closes an opened front left part of the refrigerator compartment 11. As a right upper end and a right lower end of the second pivot door 320 are respectively hinge-coupled to a right upper end and a right central part of the main body 10, and the second pivot door 320 pivots counterclockwise or clockwise, the second pivot door 320 opens and closes an opened front right part of the refrigerator compartment 11. That is, the first pivot door 310 and the second pivot door 320 are respectively installed on the left and right sides of the main body 10 and are disposed side by side in the left-right direction.
  • The first pivot door 310 includes a first door outer case 310 a forming an appearance of the first pivot door 310 and a first door inner case 310 b coupled to a rear end of the first door outer case 310 a.
  • The pivot door 300 is provided with the dispenser 330.
  • The dispenser 330 is configured such that water stored in a water supply tank (not shown) or ice stored in the ice making compartment 60 can be taken out of the refrigerator through an outlet port without opening the pivot door 300 in a state in which the pivot door 300 is closed. In the present embodiment, the dispenser 330 is provided in the first pivot door 310 installed on the left side of the main body 10.
  • Specifically, the dispenser 330 may be provided with an operation unit 333 such as a button, a lever, and the like. The user may take out the water stored in the water supply tank (not shown) or the ice stored in the ice making compartment 60 through the dispenser 330 by manipulating the operation unit 333, if necessary or desired.
  • The dispenser 330 includes an ice transfer duct 331 that is formed at the first pivot door 310 in the up-down direction, and a lower end of the ice transfer duct 331 communicates with the outlet port. When the first pivot door 310 is closed as illustrated in FIG. 9 a , an upper end of the ice transfer duct 331 communicates with the ice making compartment 60, and thus the outlet port of the dispenser 330 and the ice making compartment 60 communicate with each other. Hence, even when the first pivot door 310 is closed, the ice stored in the ice making compartment 60 can be taken out of the refrigerator through the outlet port of the dispenser 330.
  • The ice transfer duct 331 includes an ice inlet pipe 330 a supporting the gasket 332
  • The ice inlet pipe 330 a is partially spaced apart from and coupled to the ice transfer duct 331 so that the ice inlet pipe 330 a can support a coupling portion 389 to be described later.
  • The ice inlet pipe 330 a includes an upper end flange 3301 inserted into the coupling portion 389 to be described later, and a tube-shaped body 3303 extending to a lower side of the upper end flange 3301.
  • The upper end flange 3301 is an upper end perimeter of the ice transfer duct 331.
  • The gasket 332 is formed along the upper end perimeter of the ice transfer duct 331, i.e., at the upper flange 3301 and can maintain airtightness between the ice making compartment 60 and the refrigerator compartment 11 when the ice transfer duct 331 and the ice making compartment 60 communicate with each other.
  • The gasket 332 is formed to have a decreasing inclination as an upper end of the gasket 332 goes from a front side 332 a to a rear side 332 b. Detailed configuration of the gasket 332 is described later.
  • More specifically, the gasket 332 is entirely formed in an obliquely inclined shape so that a front end of the upper end is positioned higher than a rear end of the upper end.
  • The gasket 332 is formed to have a gradually decreasing inclination as it goes from the entire perimeter of the upper end to the outside of the center of the gasket 332.
  • A compartment 600 provided separately may be assembled at an upper corner of one side of the inner case 200.
  • The inner case 200 includes the compartment 600.
  • Unlike the present embodiment, the inner case 200 may be integrally formed with the compartment 600 through injection.
  • The compartment 600 may be a wall that serves as a right thermal insulation wall and a lower thermal insulation wall for forming the ice making compartment 60.
  • Configuration such as the ice maker 700 making ice and an ice storage bucket 800 storing the ice made by the ice maker 700 is accommodated inside the compartment 600.
  • FIGS. 6 and 7 illustrate partial configuration of the compartment 600. The compartment 600 includes a first lower plate 611, a first side plate 612 extending upward over an entire right end of the first lower plate 611, a first coupling plate 613 extending to the left over a part of an upper end of the first side plate 612, a first front plate 614 that has a rectangular shape and is formed such that a lower end and a right end of the first front plate 614 are respectively formed integrally at an entire front end of the first lower plate 611 and an entire front end of the first side plate 612, and a first rear plate 615 formed integrally over rear ends of the first lower plate 611, the first side plate 612, and the first coupling plate 613.
  • The first front plate 614 includes a first opening 6141 penetrated in the front-rear direction so that the ice storage bucket 800 to be described later can be taken into and out of the ice making compartment 60.
  • The first lower plate 611 is configured to form the bottom of the compartment 600. The first lower plate 611 is formed to extend in the front-rear direction.
  • As illustrated in FIG. 6 , the first lower plate 611 includes an inclination plate 6111 having an inclination θ1 that is inclined downward as a front side goes from the front to the rear. A rear side of the inclination plate 6111 is formed as a horizontal plate 6112.
  • An ice discharge port 6113 penetrated in the up-down direction is formed on the front side of the first lower plate 611, i.e., the inclination plate 6111 to be spaced apart from a front surface of the first front plate 614 to be described later.
  • The ice discharge port 6113 is a hole from which ice made by the ice maker 700 and stored in the ice storage bucket 800 is discharged. The ice discharge port 6113 is provided at the lower part of the compartment 600 to be spaced apart from the rear side of an ice making compartment door 810 to be described later.
  • As the ice discharge port 6113 is provided at the lower part of the compartment 600, a joint portion between the ice making compartment door 810 and the compartment 600, i.e., a detachable portion for opening and closing between the ice making compartment door 810 and the compartment 600 is positioned to be spaced apart from the ice discharge port 6113 at the front side of the ice discharge port 6113. Hence, a loss of cool air on a movement path of ice stored in the ice storage bucket 800 can be minimized.
  • A gasket contact portion 6119 convexly protruding downward is formed at a perimeter of a lower end of the ice discharge port 6113.
  • The gasket contact portion 6119 is formed on a lower surface of the compartment 600, i.e., on a lower surface of the inclination plate 6111 of the first lower plate 611. The gasket contact portion 6119 is formed in a ring shape along the perimeter of the lower end of the ice discharge port 6113.
  • The gasket contact portion 6119 is inclined to have a decreasing inclination as it goes from the front to the rear.
  • The gasket contact portion 6119 is a portion that is in close contact with the gasket 332 provided at the upper end of the ice transfer duct 331 formed in the dispenser 330. The gasket contact portion 6119 intensively applies a pressure to the gasket 332 to increase a sealing force and prevent a loss of cool air.
  • A separation distance in the up-down direction between the perimeter of the ice transfer duct 331 and the perimeter of the ice discharge port 6113 decreases as it goes from the front side to the rear side. A thickness of the gasket 332 positioned at the perimeter of the ice transfer duct 331 decreases as it goes from the front side 332 a to the rear side 332 b.
  • Specifically, based on the ice discharge port 6113, a separation distance in the up-down direction between the front side of the ice transfer duct 331 and the gasket contact portion 6119 is greater than a separation distance in the up-down direction between the rear side of the ice transfer duct 331 and the gasket contact portion 6119. Thus, the thickness of the gasket 332 needs to decrease as it goes from the front side to the rear side, in order to perform the sealing between the ice discharge port 6113 and the ice transfer duct 331. That is, the gasket 332 needs to be inclined so that it has a decreasing inclination as the upper end of the gasket 332 goes from the front side 332 a to the rear side.
  • Hence, the gasket contact portion 6119 smoothly pressurizes the entire perimeter of the upper end of the gasket 332 along the inclination formed in the gasket 332 when the first pivot door 310 closes the main body 10, and at the same time, is in close contact with the entire perimeter of the upper end of the gasket 332, thereby maintaining airtightness between the ice making compartment 60 and the refrigerator compartment 11.
  • Since the gasket 332 and the gasket contact portion 6119 smoothly contact each other along the inclination formed in the gasket 332 when the first pivot door 310 closes the main body 10, twisting or pushing of the gasket 332 can be prevented without adding a separate lubricating material to the gasket 332.
  • When the ice making compartment 60 is formed by the compartment 600, an entrance wall 630 and an installation wall 640 may be further included in addition to the compartment 600.
  • As illustrated in FIG. 5 , the entrance wall 630 is coupled to a front part of the compartment 600.
  • The entrance wall 630 is configured to form an entrance portion of the ice making compartment 60. The entrance wall 630 is formed in a rectangular parallelepiped shape as a whole and includes a second opening 6301 that is penetrated in the front-rear direction in a central portion.
  • An ice guide portion 6319 protruding downward is formed on a front lower plate of the entrance wall 630.
  • A lower end of the ice guide portion 6319 is formed to have the same inclination as the inclination plate 6111 of the first lower plate 611.
  • As an inside of the ice guide portion 6319 is formed to be penetrated in the up-down direction, an upper end of the ice guide portion 6319 communicates with the second opening 6301, and the lower end of the ice guide portion 6319 communicates with the ice discharge port 6113.
  • When the entrance wall 630 is coupled to the compartment 600, the lower end of the ice guide portion 6319 is inserted into the ice discharge port 6113 of the compartment 600.
  • A shape of the gasket 332 is described in detail below with reference to FIGS. 9 b and 9 c.
  • The gasket 332 includes an inner peripheral portion 381 forming a passage through which ice passing through the ice discharge port 6113 first passes among the gaskets 332, a case contact portion 383 that is connected to the outside of the inner peripheral portion 381, has an upper end in close contact with the gasket contact portion 6119, and extends to the outside, a first part 385 that is connected to a lower end of the case contact portion 383 and extends to the inside, a reduction portion 387 that is connected to a lower end of the first part 385 and extends downwardly, and a coupling portion 389 that is connected to a lower end of the reduction portion 387 and is coupled to the ice inlet pipe 330 a.
  • The inner peripheral portion 381 is formed to have a long length in the up-down direction and has a shape with a lower end rolled outward. Thus, ice can easily fall to the lower side without being caught in the inside of the case contact portion 383 of the gasket 382.
  • The inside of the case contact portion 383 is connected to an upper end of the inner peripheral portion 381, and the case contact portion 383 is formed to be inclined downward as it goes to the outside.
  • The outside of the first part 385 is connected to the lower end of the case contact portion 383, and the first part 385 extends to the inside.
  • The first part 385 is formed to have a substantially long length in the front-rear direction.
  • Since a thickness of the front side of the gasket 332 is greater than a thickness of the rear side of the gasket 332, the front side of the first part 385 is inclined downward as it goes from the front to the rear, and the rear side of the first part 385 has a shape close to being parallel to the front-rear direction as it goes from the front to the rear.
  • A thickness t1 of the front side 332 a of the gasket 332 is greater than a thickness of the rear side 332 b of the gasket 332 by the reduction portion 387. Specifically, the gasket 332 has a gradually decreasing thickness as it goes from the front side 332 a to the rear side 332 b.
  • Hence, the upper surface of the gasket 332 has a shape corresponding to the inclination plate 6111 that is inclined downwardly.
  • Accordingly, when the first pivot door 310 is opened and closed by moving in a direction of the arrow, a lower surface of the gasket contact portion 6119 formed on the inclination plate 6111 is disposed to correspond to the upper end of the gasket 332, i.e., an upper end of the case contact portion 383. Hence, changes in the thickness of the gasket 332 enable the smooth opening and closing of the first pivot door 310. Further, since the gasket 332 contacts the gasket contact portion 6119 and is pressed downward, the sealing force between the gasket 332 and the gasket contact portion 6119 is improved.
  • Based on the left side, i.e., the front side of FIG. 9 b , the reduction portion 387 includes a first reduction portion 3871 that has an upper end connected to the lower end of the first part 385 and is disposed to elongate in the up-down direction, a wrinkle portion that has an upper end connected to a lower end of the first reduction portion 3871 and forms a wrinkle in at least a part of the reduction portion 387, and a fourth reduction portion 3874 that has an upper end connected to a lower end of the wrinkle portion and is disposed to elongate in the up-down direction.
  • The wrinkle portion includes a second reduction portion 3872 that has an upper end connected to the lower end of the first reduction portion 3871 and is inclined inwardly downwardly as it goes from the upper side to the lower side, and a third reduction portion 3873 that has an upper end connected to a lower end of the lower second reduction portion 3872 and a lower end connected to the fourth reduction portion 3874 and is inclined outwardly downwardly as it goes from the upper side to the lower side.
  • In this instance, the first reduction portion 3871 and the fourth reduction portion 3874 are vertically arranged substantially parallel to each other.
  • The second reduction portion 3872 and the third reduction portion 3873 are formed to be inclined in different directions. The second reduction portion 3872 and the third reduction portion 3873 form wrinkles in the gasket and can reduce a load applied by the gasket contact portion 6119 when the first pivot door 310 is closed.
  • A front thickness and a rear thickness of the gasket 332 are different from each other. Specifically, since the front thickness of the gasket 332 is greater than the rear thickness of the gasket 332, the reduction portion 387 has a decreasing thickness as it goes from the front to the rear. Thus, as illustrated in the right side of FIG. 9 b , it can be seen that a shape of the rear side of the reduction portion 387 is almost absent. In this instance, it can be seen that the rear side of the gasket 332 has the shape in which there is no reduction portion 387 and the first part 385 and the coupling portion 389 are connected.
  • An insertion space into which the upper flange 3301 of the ice inlet pipe 330 a is inserted is formed in an inner peripheral surface of the coupling portion 389.
  • Specifically, the coupling portion 389 includes, based on the position, a coupling upper piece 3891 connected to the fourth reduction portion 3874 or the first part 385, a coupling peripheral piece 3893 that is connected to the outside of the coupling upper piece 3891 and extends downward, and a coupling lower piece 3895 that is connected to a lower side of the coupling peripheral piece 3893 and is supported on the first door inner case 310 b.
  • The coupling upper piece 3891 and the coupling lower piece 3895 are formed to extend back and forth.
  • The coupling peripheral piece 3893 is formed to extend up and down.
  • The coupling upper piece 3891 contacts an upper surface of the upper end flange 3301, the coupling peripheral piece 3893 contacts an outer perimeter of the upper end flange 3301, and the coupling lower piece 3895 contacts a lower surface of the upper end flange 3301.
  • The first part 385 is connected to the outside rather than the center of the coupling upper piece 3891.
  • Specifically, a portion of the coupling upper piece 3891 connected to the first part 385 is approximately ⅓ of a front-rear length of the coupling upper piece 3891 from the outside.
  • A front-rear length of the coupling lower piece 3895 is less than the front-rear length of the coupling upper piece 3891.
  • A front-rear length of the coupling portion 389 is less than a front-rear length of the case contact portion 383.
  • An outer end of the coupling portion 389 is disposed more inward than an outer end of the case contact portion 383.
  • The above-described shape of the gasket 332 is merely an example, and the gasket 332 can have various shapes other than the shapes described in the present disclosure.
