[0067] FIG. 3 is a drawing illustrating the configuration of the second door, (a) is a side view, (b) is a rear perspective view with the third door closed, and (c) is a rear perspective view with the third door open.

[0068] Refer to FIG. 3. A door dike 4 extending rearward from the door liner 3 may be formed. A suction port 5 may be provided on the upper surface of the door dike 4. The door liner 3 may partition the inner surface of the door. The door liner may extend primarily in the direction of up and down and the left and right direction. The door dike 4 may extend rearward from the door liner 3 to block cold air leakage. The door dike 4 may extend in the front and rear direction. The door dike may have a larger component extending in the front and rear direction than the door liner. Due to this difference in configuration, the suction port 5 may be provided in the door dike. The door dikes 4 may be connected. A space may be provided inside the connected door dike. The ice making part 42 may be disposed inside the space.

[0069] The door liner and the door dike may be referred to as a door liner without distinction. In this case, it can be said that the door liner is provided with the suction port 5. By providing the suction port 5 in the door dike 4, cold air from the item-accommodating space of the cabinet can be supplied to the first storage section 6. The cold air passing through the first and second storage sections 6, 7 can return to the item-accommodating space through the discharge port 8.

[0070] FIG. 4 is a cross-sectional view of 4-4' of FIG. 3(b). FIG. 4 shows the fourth door in a closed state.

[0071] Refer to FIG. 4. The third door 10 and the fourth door 11 can be aligned in the front and rear direction. When the fourth door 11 is closed, the cold air flow paths of the storage sections 6, 7 can be defined. When the fourth door 11 is open, the cold air flow paths of the storage sections 6, 7 can be open. The inner surface of the fourth door can be a wall defining the inner space of the storage sections 6, 7. When the fourth door is opened, the air blowing through the suction port 5 may not operate. Accordingly, the loss of cold air in the item-accommodating space of the cabinet can be prevented. When the third door 10 is opened, the air blowing through the suction port 5 may not operate. Accordingly, the loss of cold air in the first storage section 6 can be prevented.

[0072] The fourth door 11 may have a frame 111. The frame may be provided as a rectangular frame. The frame 111 may support three transparent panels 112 to 114. The transparent panels may transmit light. The user may observe the storage section through the transparent panels.

[0073] The third door 10 may have a frame 1111. The frame may be provided as a rectangular frame. A door liner 3 may be provided on the inner surface of the frame 1111. A door dike 4 may be provided forward from the door liner. A suction port 5 may be provided on the upper surface of the door dike 4. Cold air suctioned through the suction port 5 may move rearward and move to the first storage section 6. The cold air may cool items in the first storage section 6. The cold air in the first storage section may move downward.

[0074] The cold air movement path of the first storage section may include at least two. The at least two cold air movement paths may be spaced apart from each other. The cold air movement path of the first storage section may include a gap between the rear end portion of the basket 9 and the front surface of the third transparent panel 114. Cold air may move downward through the gap. This cold air movement path may be referred to as the first cold air movement path. The transparent panel may define the cold air movement path of the first storage section. The transparent panel may form a portion of the fourth door. The cold air movement path of the first storage section may include an opening or recess of the basket 9. This cold air movement path may be referred to as the second cold air movement path.

The ice-making unit may include a water supply part, a cold air supply module, an ice-making module, an ice-separating module, an ice bin, and a rapid ice-making module. Ice stored in the ice bin may be supplied upon a user's request. The rapid ice-making module may operate when supplying ice. Other ice-making units, such as the ice-making unit of FIGS. 8 and 9 of KR20230094436A disclosed as a prior art, and the flow path technology for supplying cold air to the ice maker, are included in the description of the present disclosure. Various other ice-making unit technologies may be applied to the present disclosure. The cold air supply for freezing for the ice-making unit 42 and the cold air supply for refrigeration for the storage section 6, 7 may be separated. Accordingly, cold air supply corresponding to each purpose may be possible. Accordingly, the cold air supplies may not interfere with each other.

[0076] The blowing unit 51 of the suction port 5 may be provided so as to slope downward as it goes forward. The installation angle of the blowing unit 51 may be closer to a horizontal line than a vertical line. In other words, the installation angle of the blowing unit 51 may be close to a lying position. Accordingly, even when the fourth door 11 is opened, the blowing unit may not be clearly visible.

[0077] Below the ice-making unit, a chute 421 that guides the discharge of ice from the ice-making unit 42 and a funnel 422 that drops ice into the user's disposal container can be provided. The arrangement of the chute and the funnel can be provided compactly.

[0078] Below, each component of the door is described in detail. Each component of the door can have the following effects: maintaining a thin door while still having a storage section, preventing interference between components for supplying cold air, maintaining a low temperature in the storage section, preventing temperature unevenness in the storage section, maintaining door insulation, and preventing interference with the cold air flow path.

[0079] FIG. 5 is an enlarged cross-section view of the upper portion of the door.

[0080] Refer to FIG. 5. An arbitrary extension line can be provided in the front and rear direction in the area where the ice making part 42 is installed. The extension line can include, from the frontmost to the rearmost, a first insulation wall 41, an ice making part 42, a second insulation wall 43, a storage gap 44 of the first storage section 6, a first cold air movement path 45, and a third insulation wall 46. The first insulation wall 41 can perform an insulation function for the temperature difference between the ice making space of the ice making part and the item-accommodating space. The ice making part 42 performs an ice making function using cold air at a temperature below zero. The second insulation wall 43 can perform an insulation function for the temperature difference between the ice making space of the ice making part and the first storage section. The first storage section 6 can store items and maintain a low temperature. The first cold air movement path 45 can guide the downward movement of cold air. The first cold air movement path can perform an insulation function for the temperature difference between the room temperature outside the third insulation wall 46 and the first storage section 6.

[0081] FIG. 6 is a drawing illustrating the thickness of a refrigerator door in the front and rear direction along the extension line of FIG. 5.

[0082] Refer to FIG. 6. The thickness w6 of the first insulation wall 41 in the front and rear direction, the thickness w5 of the ice making part 42 in the front and rear direction, the thickness w4 of the second insulation wall 43 in the front and rear direction, the thickness w3 of the first storage section 6 in the front and rear direction, the thickness w2 of the first cold air movement path 45 in the front and rear direction, and the thickness w1 of the third insulation wall 46 in the front and rear direction may have the following relationship. The thickness w3 of the first storage section in the front and rear direction may provide an item storage gap 44 in the door.

[0083] First, w4 may be > w6. This may be because the insulation load of the second insulation wall 43 is greater than that of the first insulation wall 41. This may be because the second insulation wall 43 may be provided with a cold air supply path and a water supply path for the ice making part. Second, w1 may be > w4. This may be because the insulation load between the external room temperature and the low temperature of the refrigerating space is the greatest. Among the various insulation walls, the thickness of the third insulation wall 46 may be the largest. Third, w3 may be > w1. This is because a length in the front and rear direction suitable for storing items must be secured. Fourth, w2 may be the shortest. This may be because the first cold air movement path is a passage of cold air in a gaseous state with smooth fluidity.

[0084] The first storage section 6 may have a different length in the front and rear direction according to the position thereof in the direction of up and down. The longest point in the front and rear direction of the first storage section may be longer than the length w1 of the third insulation wall 46 in the front and rear direction. The longest point in the front and rear direction of the first storage section may be the uppermost point of the first storage section. The longest point in the front and rear direction of the first storage section may be the upper end of the basket. The shortest point in the front and rear direction of the first storage section may be shorter than the length w1 of the third insulation wall 46 in the front and rear direction. The shortest point in the front and rear direction of the first storage section may be the lowermost point of the first storage section. The shortest point in the front and rear direction of the first storage section may be the bottom of the basket.

[0085] The thickness w4 of the second insulation wall 43 may vary in length in the front and rear direction according to the direction of up and down. The thickness w4 of the second insulation wall 43 may be thicker at the upper portion than at the lower portion. The thinner part of the thickness w4 of the second insulation wall 43 may be thinner than the first insulation wall w6. In either case, the gap necessary for the introduction of the insulating foam member can be secured.

[0086] FIG. 7 is a drawing illustrating the lower configuration illustrating the ice making part in detail.

[0087] Refer to FIG. 7. The chute 421 can guide ice discharged from the ice-making unit forward. It may be important to remove ice caught in the chute. Ice that moves forward along the chute can move downward. The funnel 422 can guide the downward movement of the ice. The chute and funnel may be arranged so that the ice falls properly into the user's gripping container, does not fall outside the funnel, and prevents clogging of the ice.

[0088] The virtual line l1 extending vertically from the rear end of the funnel can be disposed further back than the virtual line l2 extending vertically from the front end of the first storage section. Through this, ice detachment can be prevented. The ice can properly fall into the user's gripping container. The length of the first storage section in the front and rear direction can be made sufficiently long. Accordingly, the gap of the first storage section in the front and rear direction can be secured. The virtual line l1 extending vertically from the rear end of the funnel can pass through the first storage section 6. The virtual line l3 extending vertically from the rear end of the front wall of the ice making part 42 can pass through the chute 421. This can smoothly guide the ice forward. The virtual line l3 extending vertically from the rear end of the ice making part 42 can pass through the funnel. This can prevent ice clogging.

[0089] A display 69 may be provided on the refrigerator door. The display information of the display 69 can be viewed from the outside through the fourth door 11. The display may be disposed below the rear end of the first storage section 6. The first cold air movement path 45 may extend vertically along the rear surface of the display. The display may be provided by being connected to the first storage section 6. The display may be supported by the same frame as the frame supporting the first storage section 6. The identical frame may be, for example, an injection-molded plastic part that provides a single body. The upper end of the display may be disposed higher than the lower end of the ice-making unit 42 by a predetermined height h1. This can enhance user visibility.
