Background

A refrigerator having an ice making unit for making ice cubes on a door is known. For example, japanese patent laid-open No. 2010-112676 (patent document 1) discloses a refrigerator. According to patent document 1, an ice making case and a water overflow preventing member that prevents water from overflowing from the ice making case are provided. A cold air guide is provided to guide cold air from a cold air supply port to an inner side of a water overflow preventing member. The cold air is blown out from the cold air guide outlet to the inside of the water overflow preventing member. The cold air is not blocked by the water overflow preventing member, so that the water of the ice making cells is frozen. An ice making case and a water overflowing preventing member are separately provided. The ice making tray is inclined while separating the water overflowing preventing member. The ice cubes are taken out from the ice making cells without being hindered by the water overflowing preventing member. Thereby, ice is made on the refrigerator door.

Disclosure of Invention

Problems to be solved by the invention

As described in patent document 1, in the case where a user manually supplies water to the ice making unit instead of automatically making ice, when the ice making unit is fixed to the door, the user carries water to the refrigerator through a cup or the like and supplies water to the ice making unit in a state where the refrigerator door is opened. In this case, if water overflows during the water supply, the water may enter the ice bank, or the water may splash into the refrigerator. Further, since a state in which the refrigerator door is opened is made during the water supply, energy loss increases. An object of the present invention is to provide a refrigerator having a configuration for making ice or a configuration for storing ice with high convenience.

Means for solving the problems

According to one aspect of the present invention, there is provided a refrigerator including a door, an ice storage portion, and an ice making portion detachably disposed on the door above the ice storage portion.

Effects of the invention

As described above, according to the present invention, there is provided a refrigerator having a configuration for making ice or a configuration for storing ice with high convenience.

Detailed Description

Embodiments of the present invention will be described below with reference to the drawings. In the following description, the same components are denoted by the same reference numerals. The names and functions of these are also the same. Therefore, detailed description thereof will not be repeated.

< first embodiment >

As shown in fig. 1, the ice making unit 100 according to the present embodiment is disposed in a refrigerator 200 having a freezing chamber 201. As shown in fig. 1 and 2, the ice-making unit 100 is configured to be placed inside a door 210 for a freezing chamber 201. The following describes types of two ice-making units 100, 100 that may be disposed on the door 210.

As shown in fig. 3, each ice-making unit 100 may be detached from the door 210 and placed in the freezing compartment 201 or a table, etc.

In particular, as will be described later, the ice making unit 100 according to the present embodiment is divided into an ice making unit 110 shown in fig. 4 and an ice storage unit 130 shown in fig. 5. That is, it is configured such that the lower portion of the ice making part 110 and the upper portion of the ice storage part 130 are opposite to and overlap each other. As will be described later, the lower portion of the ice making unit 110 and the upper portion of the ice storage unit 130 may be detachably attached.

In the present embodiment, the bottom of the ice making unit 110 may be horizontally formed, and the ice making unit 110 may be horizontally placed in the freezing chamber. Similarly, the bottom of the ice bank 130 is also horizontally formed, and the ice bank 130 may also be horizontally placed in the freezing chamber.

Referring to fig. 6, the ice making unit 100 according to the present embodiment is used by inserting an ice making tray 120 into an ice making housing 111 of an ice making unit 110. An upper cover 112 is mounted on the upper surface of the ice making box 111. The upper cover 112 has an opening at a central portion thereof to serve as a water inlet before ice making.

An ice bank 131 of the ice bank 130 shown in fig. 5 is detachably mounted at a lower portion of the ice making bank 111. The ice bank 132 is inserted onto the ice bank 131 from the left side.

More specifically, an opening 111Y is formed in the front surface of the upper portion of the ice making housing 111. The ice tray 120 is inserted into the opening 111Y from the front. The ice tray 120 is configured by, for example, an ice cube tray 121, cover members 122L and 112R, a rotation mechanism for the ice cube tray 121, and the like. The present embodiment is configured such that the ice-making tray 120 is mounted on the ice-making housing 111, and when ice making is completed, the user rotates the rotating lever 125 and the ice cube tray 121 with respect to the ice-making tray 120 to drop ice cubes in the ice cube tray 121 into the ice storage tray 132.

As shown in fig. 7 to 9, the ice cube tray 121 according to the present embodiment is formed with a first vertical partition 1213 and a second vertical partition 1214 for partitioning water injected into the ice cube tray 121 in the left-right direction. That is, in the present embodiment, the plurality of first horizontal separators 1211 and the plurality of second horizontal separators 1212 form two rows with the first vertical separators 1213 and the second vertical separators 1214 interposed therebetween. In more detail, first vertical partitions 1213 are formed at the foremost and rearmost sides (front and rear of the ice making compartment 121) of the ice making compartment 121, and a plurality of second vertical partitions 1214, 1214 are formed therebetween.

A groove 1211X is formed on an upper portion of the first lateral partition 1211 toward an inner side of the ice making tray 121. A groove 1212X is formed on an upper portion of the second cross partition 1212, toward an outer side of the ice making housing 121. A groove 1213X is formed on the upper portion of the first vertical partition 1213. No groove is formed in the upper portion of the second vertical partition 1214.

As described above, since the grooves 1211X, 1212X, 1213X are formed in the ice making cells 121, the water is rapidly diffused into all the partitioned areas through the grooves 1211X, 1212X, 1213X regardless of the water supply from any position.

In the present embodiment, since the positions of the grooves 1211X and 1212X formed in the first lateral partition 1211 and the second lateral partition 1212 facing each other are different from each other, for example, when the door 210 is opened and closed, even if centrifugal force or inertial force is applied to the water in the ice cube tray 121 due to the opening and closing operation of the door 210, it is possible to prevent the water from passing through the grooves 1211X, 1211X and 1211X all at once. That is, even if centrifugal force is generated due to the rotation of the door 210, the water having passed through the grooves 1211X collides with the portion of the second lateral partition 1212 where the grooves 1212X are not formed and loses momentum, and the water passing through the grooves 1212X collides with the portion of the first partition 1211 where the grooves 1211X are not formed and loses momentum, so that the possibility of water splashing from the front end portion or the rear end portion of the ice-making housing 121 may be reduced.

Further, a wall surface 1215 is formed at the front end of the ice making tray 121 to make it difficult for water to overflow outward. A wall surface 1216 is also formed at the rear end of the ice making tray 121 to make it difficult for water to overflow outside. With this configuration, for example, when the door 210 is opened or closed, the possibility of water splashing from the front end or the rear end of the ice cube tray 121 due to centrifugal force or the like can be reduced. Further, a cover member described later may be attached to the right or left end of the ice making tray 121.

As shown in fig. 10 to 12, in the ice making tray 120, the front member 127 and the rear member 128 are joined by a right member 129R and a left member 129L. That is, the front member 127, the right member 129R, the rear member 128, and the left member 129L form a rectangular frame. Thus, the ice tray 120 holds the ice cube tray 121 inside the frame.

And, the ice making tray 121 is rotatably held by the front and rear members 127 and 128. In more detail, the front of the ice making housing 121 is coupled to the rear of a rotating lever 125, and the rotating lever 125 is rotatably held in a front member 127. After the supplied water becomes a plurality of ice cubes, the user rotates the ice making tray 121 by rotating the rotating lever 125 and drops the ice cubes into the ice storage tray 132.

In more detail, an abutment member 126 is installed at the rear of the ice making compartment 121, and when the user rotates the ice making compartment 121 by 180 °, the abutment member 126 collides against the rear member 128 and the rear of the ice making compartment 121 cannot be further rotated. Thereby, the ice making tray 121 is twisted, and the ice in the ice making tray 121 is separated from the ice making tray 121 and falls into the ice storage tray 132.

In particular, in the present embodiment, lid member 122R is attached to the upper surface of the right end portion of ice making tray 121 so as to face upward. A cover member 122L is attached to the upper surface of the left end portion of the ice making tray 121 so as to face upward. Water supplied to ice cube tray 121 is less likely to be splashed in the left-right direction of ice tray 120 by covers 122L and 122R.

Further, in the present embodiment, as shown in fig. 10 to 13, the outer peripheries of the covers 122L and 122R are formed in a shape along a circle having a rotation axis of the ice cube tray 121 as a center so as not to collide with the inside of the ice making housing 111 when the ice cube tray 121 rotates, and the radius of the circle is a distance from the right or left end of the ice cube tray 121.

Thus, water splashing from the ice making cells 121 may be reduced without increasing the size of the ice making part 110.

The outer peripheries of the front and rear wall surfaces 1215 and 1216 may have a shape along the circle. At this time, the outer peripheries of the front and rear wall surfaces 1215 and 1216 may be formed in a shape extending along a circle at a height substantially equal to the height of the adjacent lids 122L and 122R, and a horizontally cut-away shape may be formed at a height higher than the lids 122L and 122R. Thereby, the splashing of water from the ice making tray 121 is reduced while suppressing the ice making tray 121 from becoming difficult to twist.

In the present embodiment, as shown in fig. 13, a left opening 112L is formed in the left side wall of the ice making tray 111 on the left side of the ice making tray 120, the ice making tray 121, or the cover members 122L and 122R. Thereby, it is configured to facilitate introduction of cool air into the ice making housing 111 and to easily cool the ice making compartment 121. A cover 113L is formed at an upper portion of the left opening 112L so as to face the inside of the ice tray 111 and obliquely downward. This structure prevents water from splashing outward from the left opening 112L when water is supplied to the ice cube tray 121.

Similarly, a right opening 112R is formed in the right side wall of the ice making case 111 on the right side of the ice making tray 120, the ice making case 121, or the cover members 122L and 122R. This makes it easy to cool the ice cube tray 121. A cover 113R is formed on the upper portion of the right opening 112R so as to face the inside of the ice tray 111 and obliquely downward. This structure prevents water from splashing outward from the right opening 112R when the water is supplied to the ice cube tray 121.

Next, a configuration for mounting the ice-making unit 100 on the door 210 of the refrigerator 200 will be described. Referring to fig. 14, in the present embodiment, engagement pieces 212, 212 are attached to a wall surface 211 of a door 210 of a refrigerator 200 at positions facing an ice making unit 110. Further, a lower cover 220 is attached to the door 210 of the refrigerator 200 below the engaging pieces 212, and 212, that is, at a position facing the ice bank 130.

Referring to fig. 14 and 15, the ice making box 111 of the ice making unit 100 is attached to the engaging pieces 212, and the ice bank 131 is attached to the lower cover 220.

More specifically, as shown in fig. 15 and 16, a slit 111X is formed in the front-rear direction in the upper portion of the ice making case 111. The user hooks the engaging pieces 212, 212 to the slit 111X of the ice making housing 111 of the ice making unit 100.

Further, a hook 220X is formed on an upper portion of the lower cover 220. A hook 131X is also formed on the left side of the ice bank 131. And, the user hooks the hook 131X of the ice bank 131 of the ice-making box 100 on the hook 220X of the lower cover 220.

As described above, in the ice making unit 100 according to the present embodiment, since the ice making unit 110 can be detached from the door 210 separately from the ice storage unit 130, only the ice making unit 110 can be carried to the faucet to replenish water. Further, it is possible to horizontally place only the ice making unit 110 in ice making in the freezing chamber, thereby more rapidly making ice cubes, or to place only the ice storage unit 130 storing ice cubes on the freezing chamber or the table.

< second embodiment >

The configuration for mounting the ice-making unit 100 on the door 210 of the refrigerator 200 is not limited to the configuration of the above-described embodiment. Referring to fig. 17 to 20, in the present embodiment, engaging pieces 215A, 215B, and 215C are attached to door 210 of refrigerator 200 at positions facing ice making unit 110. Further, in the door 210 of the refrigerator 200, as in the above-described embodiment, a lower cover 220 is attached below the engaging pieces 215A, 215B, 215C, that is, at a position facing the ice bank 130.

The engaging piece 215A is formed with a horizontal rib 216 for hooking a front portion of the slit 111X of the ice-making housing 111 on the rear side, and a vertical rib 217A for guiding a rear end of the ice-making housing 111 on the rear side.

The engaging piece 215B is formed with a horizontal rib 216 for hooking a front portion of the slit 111X of the ice-making housing 111 on the rear side, a horizontal rib 216 for hooking a rear portion of the slit 111X of the ice-making housing 111 on the front side, and a vertical rib 217B for guiding a front end of the ice-making housing 111 on the rear side and a rear end of the ice-making housing 111 on the front side.

The engaging piece 215C is formed with a horizontal rib 216 for hooking the front portion of the slit 111X of the ice-making housing 111 on the front side, and a vertical rib 217C for guiding the front end of the ice-making housing 111 on the front side.

As described above, in the ice-making unit 100 according to the present embodiment, the slits 111X of the ice-making housing 111 are hooked on the horizontal ribs 216, so that the ice-making housing 111 can be easily attached to the door 210. Thus, even in a state where water is supplied to the ice making housing 121 within the ice making housing 111, the user may mount the ice making housing 111 to the door 210 without sprinkling water. Further, since the vertical rib 217 limits the movement of the ice making housing 111 in the front and rear direction, it is possible to prevent the water from overflowing due to the movement of the ice making housing 111 by the opening and closing operation of the door 210. Further, by moving the ice making part 110 upward in a horizontal state, the user can easily detach the ice making part 110 from the door 210 independently of the ice storage part 130.

< third embodiment >

Alternatively, as shown in fig. 21, only the ice bank 130 may be attached to and detached from the door 210. That is, the ice-making unit 100 is mounted to the door by the hook portion 220X of the upper portion of the lower cover 220 and the hook portion 131X of the ice bank 131 without providing an engaging piece on the door 210.

In the present embodiment, the ice making unit 110 is preferably placed on the ice storage unit 130 so that the ice making unit 110 and the ice storage unit 130 are not deviated from each other in the front, rear, left, and right directions.

For example, a lower portion of the ice making part 110 may be fitted to an upper portion of the ice storage part 130, or conversely, an upper portion of the ice storage part 130 may be fitted to a lower portion of the ice making part 110.

Alternatively, magnets may be embedded in the lower portion of the ice making part 110 and the upper portion of the ice storage part 130 to couple the two by magnetic force.

Alternatively, the ice making unit 110 and the ice storage unit 130 may be configured not to be displaced in the front, rear, left, and right directions by forming a convex portion or a concave portion around the lower portion of the ice making unit 110 and forming a concave portion or a convex portion around the upper portion of the ice storage unit 130 and fitting them.

< fourth embodiment >

In the above embodiment, the ice making unit 110 can be detached from the door 210 independently of the ice storage unit 130. However, the ice storage unit 130 may be separated from the ice making unit 110 and detached from the door 210.

For example, as shown in fig. 22(a), the ice making unit 110 and the ice storage unit 130 are configured to be detachable from the door 210. In the present embodiment, a gap in the vertical direction is formed between the ice making unit 110 and the ice storage unit 130 in a state where the ice making unit 110 and the ice storage unit 130 are attached to the door 210.

With such a configuration, in the ice-making unit 100 according to the present embodiment, as shown in fig. 22(B), the ice storage unit 130 and the door 210 can be disconnected from each other by slightly lifting the ice storage unit 130 while maintaining the ice-making unit 110 attached to the door 210. As shown in fig. 22(C), only the ice bank 130 can be pulled out from the door 210 while maintaining the ice making unit 110 mounted on the door 210.

< fifth embodiment >

Alternatively, as shown in fig. 23 and 24, the ice making unit 100 may have only the ice making part 110. Also, the shelf 230 mounted on the door 210 may be used as an ice bank.

< sixth embodiment >

In the above embodiment, two ice-making units 100 and 100 are mounted on one door 210. However, in the refrigerator 200, one ice-making unit 100 may be mounted on one door 210, or a plurality of ice-making units 100 may be mounted on one door 210.

< summary >
