[44] Reference will now be made in detail to the specific embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[45] As shown in FIG. 1, a refrigerator having a grain keeping apparatus according to the present invention includes a body 10 in which a refrigerator compartment 12 and a freezer compartment (not shown) are formed and doors 14 and 15 rotatably coupled to a front of the body 10 to open and close the refrigerator compartment 12 and the freezer compartment, respectively.

[46] A grain keeping apparatus 20 is provided in the door 14 opening and closing the refrigerator compartment 12.

[47] Here, the grain keeping apparatus 20 is provided in an inner lower portion <£ the door 12, considering a position for grain to be put and taken out easily. The grain keeping apparatus 20 includes a grain box 30, a grain discharging part 60 and a grain drawing part 300. Grain is put and preserved in the grain box 30. The grain discharging part 60 discharges the grain of the grain box 30 downward. The grain drawing part 300 is coupled to a lower portion of the grain discharging part 60 to hold the grain discharged from the grain discharging part 60 before the grain being drawn out.

[48] A shelf 33 is detachably provided on the grain box 30 and a closable member 31 is provided in front of the shelf 33 to open and close an opening (not shown) of the grain box 30.

[49] An image display part 16 and an alarm part 17 may be provided on a front of the door 15 for opening and closing the freezer compartment (not shown). An operational condition of the refrigerator is displayed on the image display part 16. An outer speaker is provided at the alarm part 17 to make alarm sound.

[50] Here, a user may identify an operational condition of the refrigerator and a sufficient/insufficient amount of the grain via a personal mobile communication terminal 18, which may be embodied by using a controller (2, see FIG. 2) and wireless communication which will be described later.

[51] As shown in FIG. 2, the shelf 33 is provided at the opening 36 formed at a top of the grain box 30. The shelf 33 is configured of a first shelf 34 and a second shelf 35 and the closable member 31 is rotatably coupled to a front portion of the opening 36, in front of the shelf 33.

[52] An inner space of the grain box 30 is partitioned by a partition 37 so that various kinds of grains may be put and kept in the grain keeping box 30 separately. In the drawing, the inner space of the grain keeping box 30 is partitioned into two spaces and the present invention is not limited thereto, for example, into plural spaces.

[53] A transparent member 38 is provided in a front portion of the grain box 30 for a user to identify an amount and a kind of grain held in the grain box 30 and whether the grain is insufficient.

[54] The grin discharged from the grain box 30 is dropped and kept in the grain drawing part 300 by an operation of the grain discharging part 60. Here, the grain discharging part 60 includes an operational button 62 installed at a front plate 40 of the grain box 30. if the user pushes the operational button 62, a lower portion of the grain box 30 is opened and the kept grain is discharged. If the pushing of the operational button 62 is stopped, the lower portion of the grain box 30 is closed and the discharging of the grain is stopped.

[55] As mentioned above, the grain drawing part 300 is coupled to the lower portion of the grain discharging part 60. The grain drawing part 300 includes a grain drawing box 310 and a housing 320. The grain is dropped in the grain drawing box 310. The grain drawing box 310 is held in the housing 320, slidingly movable.

[56] A first securing member 16 that is projection shaped is provided at an inner side surface 15 of the door 14. A second securing portion 30a, 33a, 60a and 100a that is groove shaped is provided at both side surfaces of the shelf 33, the grain box 30, the grain discharging part 60 and the grain drawing part 300, respectively. Then the first securing member 16 is inserted in each of the second securing portion 30a, 33a, 60a and 100a.

[57] As shown in FIG. 3, the grain drawing box 310 has an open top and a grip 311 is formed at a front portion so that a user may draw the drawing box 310 by using the grip 311 smoothly.

[58] Here, it is preferable that the grain drawing box 310 is formed of transparent material to for the user to identify keeping objects in the grain drawing box 310.

[59] An opening 321 is formed at the housing 320 so that the grain drawing box 310 may pass through, moving slidingly. Plural keeping spaces 322 for holding the grain drawing box 310 are formed in the housing, in communication with the opening 321. a partition 323 is formed between the keeping spaces 322 so that each of the keeping space is defined separately.

[60] Accordingly, plural grain drawing boxes 310 corresponding to the keeping spaces

322 are provided to keep different kinds of grains in the keeping spaces 322, respectively, not mixed with each other.

[61] A first and second fixing part 325 and 327 may be formed at a bottom of the housing 320 to prevent the grain drawing box 310 from moving in the keeping space 322 or from going off from the corresponding keeping space 322 because of an external shock. A third and fourth fixing part 315 and 317 may be formed at a bottom of the grain drawing box 310 to be engaged to the first and second fixing part 325 and 327, respectively.

[62] A hooking protrusion 330 is formed at a front portion of the bottom of the housing

320 so that a front side of the grain drawing box 310 is engaged to the hooking protrusion 330 to prevent the grain drawing box 310 from going off from the keeping space.

[63] Here, the first fixing part 325 is projection-shaped and it is projected from the bottom of the housing and the third fixing part 315 is recessed and it is formed at an outer bottom of the grain drawing box 310, having appearance corresponding to the first fixing part 325, so that the first fixing part 325 is inserted in the third fixing part 315

[64] The second fixing part 327 is long groove-shaped at the bottom of the housing 320 and the fourth fixing part 317 is projection-shaped, able to be inserted in the second fixing part 327.

[65] Here, the first and third fixing part 325 and 315 may prevent the grain drawing box

310 from moving in a forward and backward direction in case of external shock and the second and fourth fixing part 327 and 317 may prevent the grain drawing box 310 from moving in a right and left direction by the external shock. The hooking protrusion 330 is inserted in the recess formed at below the grip 311 to prevent the grain drawing box 310 from moving in any direction.

[66] As a result, even if there is a shock caused by the external shock including the opening and closing of the door, the grain drawing box 310 may separate from the housing 320.

[67] As shown in FIG. 4, a scale mark 350 is provided at a front surface of the grain drawing box 310 so that the user may recognize the amount of the grain kept in the grain drawing box 310 visually.

[68] A gap (A) formed between the partition 323 and the grain drawing box 310 is formed on purpose for the user to perform the drawing of the grain drawing box 310.

[69] Even with such the gap (A) the grain drawing box 310 can be positioned securely in the housing 320 because of the hooking protrusion 330 or the first, second third and fourth fixing part (325, 327, 315 and 317, see FIG. 3). As a result, in spite cf the shock caused when the user closes the door 14 and 15 too hard or when an external object collides against the refrigerator, the grain drawing box 310 is prevented from separating from the housing 320.

[70] As shown in FIG. 5, a front width of the keeping space 322 of the housing 320 is different from a rear width thereof. Specifically, the width (Wl) of the opening 321 provided at the front portion of the keeping space 322 is larger than the width (W2) of an inner rear portion of the keeping space 322.

[71] The reason why the widths (Wl and w2) are different is that the rear portion of the keeping space 322 may secure the rear portion of the grain drawing box 310 when the grain drawing box (310, see FIG. 3) is inserted in the keeping space 322.

[72] That is, the inner front width (Wl) of the keeping space 322 may be larger than the width cf the grain drawing box 310 so that the grain drawing box 310 may be drawn smoothly from the keeping space 322 when the user take out the grain drawing box 310. however, the inner rear width (W2) of the keeping space 322 is substantially similar to the width of the grain drawing box 310 and thus the grain drawing box 310 is secured to the rear portion of the keeping space 322 even if the external shock is applied to the refrigerator.

[73] Since the rear width (W2) is different from the front width (Wl) together with the first and second fixing part 325 and 327 and the hooking protrusion 330, the grain drawing box 310 may be securely positioned in the housing 320 even in case of the external shock to the refrigerator.

[74] As shown in FIG. 6, seeing a side section of the grain drawing box 310 held in the housing 320, the first fixing part 325 is inserted in the third fixing part 315 and the hooking protrusion 330 is inserted in the recess formed below the grip 311 only to secure safety of the grain drawing box 310.

[75] FIG. 7 illustrates another embodiment that includes an oblique surface 370 formed at the bottom of the housing and an oblique lower surface 371 formed at the bottom of the grain drawing box 310, corresponding to the oblique surface 370.

[76] Here, the oblique surface 370 may be inclined down from a front portion to a rear portion.

[77] Because of this configuration, the grain drawing box 310 is prevented from moving forward by the oblique surface 370 and the position of the grain drawing box 310 is secure.

[78] At this time, it is preferable that a friction material or a projection is attached to at least one of the oblique surface 370 and the oblique bottom 371 to heighten the coefficient of friction between the oblique surface 370 and the oblique bottom 371 and thus to enhance the position security of the grain drawing box 310.

[79] As shown in FIG. 8, there may be provided a control unit 3 that receives a signal for controlling a temperature of the refrigerator and cool air spray and for identifying an appropriate amount of grain and that transfers a signal of grain keeping condition or insufficiency of the grain to the alarm part 17 or a personal mobile wireless communication terminal outside the refrigerator.

[80] With an input stage of the control unit 3 is connected a power unit 1 for supplying electricity and a sensor 5 provided in the grain box. The sensor 5 determines whether the amount of grain is appropriate and transfers the result to the control unit 3.

[81] With an output stage of the control unit 3 is connected the alarm part 17 for generating a sound signal and the display unit 200 for generating a visual signal, here, the display unit 200 may include the image display part 16 and the personal mobile wireless communication terminal 18 that are provided at the door (15, see FIG. 1).

[82] As shown in FIG. 9, the grain keeping apparatus includes the grain box 30 provided in the upper portion thereof, the grain discharging part 60 in the center portion and the grain drawing part 300 in the lower portion.

[83] A grain outlet 41 and an oblique-shaped guide duct 43 are provided under the grain box 30. the grain (G) is discharged through the grain outlet 41 and the guide duct 43 guides the grain to the grain outlet 41.

[84] The grain discharging part 60 for adjusting the motion of the grain into the grain drawing box 300 is provided below the grain outlet 41. the grain discharging part 60 includes an operational button 62 for the user to push, an elastic member 69 for restituting an original position of the operational button 62 by elastically supporting the operational button 62 when the pushing of the operational button 62 is stopped, a grain transfer container 151 connected with the operational button 62 to hold the grain therein, and a casing 152 for rotatably holding the grain transfer container 151.

[85] In addition, a support 153 having a curvature is provided at the casing 152.

[86] The grain transfer container 151 is semi cylinder-shaped with an open portion. If the operational button 62 is not pushed, the grain transfer container 151 is in communication with the grain box 30 and it holds the grain together with the support 153 and if the operational button 62 is pushed, the grain transfer container 151 rotates to reverse its position. As a result, the kept grain is transferred to the grain drawing part 300.

[87] Here, the grain drawing part 300 includes the grain drawing box 310 in a drawer shape and the housing 320 for holding the grain drawing box 310. The grain transferred by the grain transfer container 151 is dropped to the grain drawing box 310 such that the grain is stored in a drawable state.

[88] The sensor (5, see FIG. 8) provided in the grain box 30 to determine whether the amount of the grain is sufficient may be configured as a position sensor 5a for sensing whether the grain amount is sufficient by measuring a height of the grain accumulated at an inner rear suriace of the grain box 30, or as a pressure sensor 5b provided at an upper suriace of the guide duct 43 of the grain box 30 to sense a pressure generated by the weight of the grain.

[89] Next, an operation of the refrigerator according to the present invention will be described in reference to corresponding drawings. [90] As shown in FIG. 10, the grain discharging part 60 is provided between the grain box 30 and the grain drawing part 300 to move the grain from the grain box 30 to the grain drawing part 300. [91] The grain discharging part 60 includes a driving force generation part 61 for generating a driving force and a grain transfer part 150 connected with the driving generation part 61 to transfer the grain of the grain box 30 into the grain drawing box

310 of the grain drawing part 300. [92] Here, the driving force generation part 61 includes the operational button 62 and a rack gear 64 connected with the operational button 62, and the elastic member 69 for elastically supporting the operational button 62. [93] The grain transfer part 150 includes the grain transfer container 151 having a semicylinder shape, the casing 152 in which the grain transfer container 151 is rotatably held, and a gear 157 connected with the grain transfer container 151 to rotate the container 151, being engaged to the rack gear 64. [94] Because of such that configuration, a lower portion of the rack gear 64 is engaged to an outer circumference of the gear 157 if the user may not push the operational button 62. Then, the grain (G) is held in the grain box 30, the grain transfer container

151 of the grain transfer part 150 and the casing 153. [95] Here, the grain transfer container 151 is configured to have some open portion of its outer circumference in a cylinder shape and it forms the space for holding the grain

(G) together with an inner surface cf the curvature support 153 provided in the casing

153. [96] As shown in FIG. 11, if the user pushes the operational button 62, the operational button 62 may descend and the rack gear 64 also may descend such that the gear 157 rotates according to the motion of the rack gear 64. [97] The rotation of the gear 157 leads to the rotation f the grain transfer container 151.

As the grain transfer container 151 rotates, the inner space of the grain transfer container 151 is shut off from the inner space of the grain box 30 and the inner space of the grain transfer container 151 is in communication with the inner space of the grain drawing box 310. [98] Then, the grain (G) held in the grain transfer container 151 is dropped into the grain drawing box 310 by the gravity and it is stored in the grain drawing box 310 to be taken out. [99] Hence, as shown in FlG. 12, the user takes off his/her hand from the operational button 62, the operational button 62 moves upward again by the restitution of the elastic member 69. the position of the grain transfer container 151is restituted by the upward motion of the rack gear 64 and the rotation of the gear 157, such that the inner space of the grain transfer container 151 is in communication with the inner space of the grain box 30 and some of the grain inside the grain box 30 is transferred to the grain transfer container 151 again.

[100] Hence, if the user lifts the grain drawing box 310 having some grain held therein a little bit and grabs and pulls the grip 311, the grain drawing box 310 may be drawn out from the housing 320 easily.

[101] In reference to FIGS. 8 and 9, the sensing of the grain amount will be described.

[102] If it is repeated for several times that the user introduces the grain into the grain box

30 and moves the grain drawing part 300 outside by using the grain discharging part 60, the amount of the grain in the grain box 30 is reducing gradually.

[103] If then, the sensor (5; 5a and 5b) connected with the control unit 3 checks the grain amount continuously and transfers a signal for information of the grain amount to the control unit 3 continuously. If the sensor 5 determines based on the inputted information of the control unit 3 that the grain amount is below a predetermined standard as performing the above process, the control unit 3 transfers a kind of a warning signal to inform the user of the grain amount.

[104] Specifically, such the warning signal is embodied by a vial signal and a sound signal. The control unit 3 transfers an output signal to the alarm part 17 and the sound signal is generated.

[105] The visual signal is displayed as SMS on a screen of the personal mobile terminal

18 by the image display part 16 attached on the refrigerator or the wireless communication between the terminal 18 and the control unit 3.

[106] As a result, the user can recognizes whether the grain amount is sufficient or insufficient by the sound signal of the alarm part 17 or the visual signal displayed on the image display part 16 or the personal mobile terminal 18. Moreover, the user can refill the grain in the grain box 30.

[107] 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. Industrial Applicability

[108] The present invention has an industrial applicability. [109] First, user convenience may be enhanced and freshness of grain may be maintained for a longer time, because it is more convenient to refrigerate grain according to the grain keeping apparatus for a refrigerator of the present invention.

[110] Furthermore, various kinds of grains may be kept separately but they may be taken out conveniently according to the grain keeping apparatus of the present invention.

[Ill] A still fiirther, even if a door of a refrigerator is closed too strongly or external shock is applied to the refrigerator, the grain keeping apparatus is positioned in a housing continuously and structural safety may be secured.

[112] Lastly, in case grain is put in the grain box, a user can visually identify an amount and kind cf grain from an outside of the grain box through a transparent member. As a result, user convenience may be improved and high class exterior may be achieved additionally.
