Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.
<First Embodiment>

The ice making unit 100 according to the present embodiment is arranged in a refrigerator 200 having a freezer compartment 201 as shown in FIG. As shown in FIGS. 1 and 2, the ice making unit 100 is configured to be placed inside a door 210 for the freezer compartment 201. Below, the type which can arrange | position two ice-making

units

100 and 100 to the door 210 is demonstrated.

Each of the ice making units 100 can be removed from the door 210 and placed in the freezer compartment 201 or on a desk, as shown in FIG.

Particularly, 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, as will be described later. In other words, the lower part of the ice making unit 110 and the upper part of the ice storage unit 130 are configured to overlap each other. As will be described later, the lower part of the ice making unit 110 and the upper part of the ice storage unit 130 may be configured to be detachable.

And in this Embodiment, the bottom part of the circumference | surroundings of the ice making part 110 is formed horizontally, and the ice making part 110 can be mounted horizontally in a freezer compartment. Similarly, the bottom of the ice storage part 130 is also formed horizontally, and the ice storage part 130 can also be placed horizontally in the freezer compartment.

Referring to FIG. 6, ice making unit 100 according to the present embodiment is used when ice making tray 120 is inserted into ice making case 111 of ice making unit 110. An upper cover 112 is attached to the upper surface of the ice making case 111. The upper cover 112 is opened at the center and serves as a water inlet before ice making.

An ice storage case 131 of the ice storage unit 130 as shown in FIG. 5 is detachably attached to the lower part of the ice making case 111. An ice storage tray 132 is inserted into the ice storage case 131 from the left.

More specifically, an opening 111 Y is formed on the upper front surface of the ice making case 111. The ice making tray 120 is inserted into the opening 111Y from the front. The ice making tray 120 includes, for example, an ice making tray 121,

cover members

122L and 122R, a rotation mechanism for the ice making tray 121, and the like. In the present embodiment, when ice making tray 120 is attached to ice making case 111 and ice making is completed, the user rotates rotation lever 125 and ice making plate 121 with respect to ice making tray 120 to make ice making plate 121. The ice is dropped onto the ice storage tray 132.

As shown in FIGS. 7 to 9, the ice tray 121 according to the present embodiment includes a first vertical partition 1213 and a second vertical partition 1214 for partitioning water injected into the ice tray 121 in the left-right direction. Is formed. That is, in the present embodiment, the plurality of first horizontal partitions 1211 and the plurality of second horizontal partitions 1212 are for two rows with the first vertical partition 1213 and the second vertical partition 1214 interposed therebetween. Is formed. More specifically, a first vertical partition 1213 is formed at the forefront and the rearmost of the ice tray 121, and a plurality of second

vertical partitions

1214, 1214,.

In the upper part of the first horizontal partition 1211, a groove 1211X is formed from the inside of the ice tray 121. A groove 1212 X is formed in the upper part of the second horizontal partition 1212 from the outside of the ice tray 121. A groove 1213X is formed in the upper part of the first vertical partition 1213. No groove is formed in the upper part of the second vertical partition 1214.

Thus, since the

grooves

1211X, 1212X, and 1213X are formed in the ice tray 121, even if water is supplied from any position, the water quickly passes through the

grooves

1211X, 1212X, and 1213X. It diffuses into the partition.

Moreover, in the present embodiment, the first horizontal partition 1211 and the second horizontal partition 1212 that face each other are different in the positions of the

grooves

1211X and 1212X that are formed. For example, when the door 210 is opened and closed, Even if a centrifugal force or an inertial force is applied to the water in the ice tray 121 by the opening / closing operation of the door 210, the water can be prevented from passing through the

grooves

1211X, 1211X, 1211X at a stretch. That is, even if there is a centrifugal force or the like due to the rotation of the door 210, the water that has passed through the groove 1211X hits a portion where the groove 1212X of the second horizontal partition 1212 is not formed, and lost momentum, and passed through the groove 1212X. Since the water collides with a portion where the groove 1211X of the first horizontal partition 1211 is not formed and loses momentum, the possibility of the water jumping out from the front end portion or the rear end portion of the ice tray 121 can be reduced.

Furthermore, a wall surface 1215 is formed at the front end of the ice tray 121 so that water does not easily spill out. A wall surface 1216 is also formed at the rear end portion of the ice tray 121 so that water does not easily spill out. Even with such a configuration, for example, when the door 210 is opened and closed, the possibility of water jumping out from the front end portion or the rear end portion of the ice tray 121 due to centrifugal force or the like can be reduced. Further, a cover member to be described later can be attached to the right end portion or the left end portion of the ice tray 121.

As shown in FIGS. 10 to 12, in the ice making tray 120, a front member 127 and a rear member 128 are connected 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 constitute a rectangular frame. In this way, the ice making tray 120 holds the ice making tray 121 inside the frame.

Then, the ice tray 121 is rotatably held by the front member 127 and the rear member 128. More specifically, the front portion of the ice tray 121 is connected to the back surface of the rotation lever 125 that is rotatably held in the front member 127. After the supplied water becomes a plurality of ices, the user rotates the ice making tray 121 by rotating the rotation lever 125 to drop the ice onto the ice storage tray 132.

More specifically, the abutting member 126 is attached to the rear part of the ice tray 121. When the user rotates the ice tray 121 by 180 °, the abutting member 126 hits the rear member 128, and the rear part of the ice tray 121 is more than that. It will not rotate. In this way, the ice tray 121 is twisted, and the ice in the ice tray 121 leaves the ice tray 121 and falls onto the ice storage tray 132.

Particularly in the present embodiment, a cover member 122R is attached to the upper surface of the right end portion of the ice tray 121 upward. The cover member 122 L is also attached upward on the upper surface of the left end portion of the ice tray 121. The

cover members

122L and 122R make it difficult for water supplied to the ice tray 121 to scatter in the left-right direction of the ice making tray 120.

Further, in the present embodiment, as shown in FIGS. 10 to 13, the

cover members

122L and 122R are configured so that the

cover members

122L and 122R do not collide with the inside of the ice making case 111 when the ice tray 121 is rotated. The outer periphery of 122R is formed in a shape along a circle centered on the rotation axis of the ice tray 121 and having a distance from the right end or the left end of the ice tray 121 as a radius.

Thus, the splash of water from the ice tray 121 can be reduced without increasing the size of the ice making unit 110.

Note that the outer peripheries of the front and rear wall surfaces 1215 and 1216 may also have a shape along the above-described circle. At this time, the outer periphery of each of the front and rear wall surfaces 1215 and 1216 has a shape along a circle at a height substantially the same as the height of the

adjacent cover members

122L and 122R, and the portion above the height of the

cover members

122L and 122R is It is good also as a shape cut out horizontally. Thereby, it can suppress that the ice-making tray 121 becomes difficult to be twisted, reducing the scattering of water from the ice-making tray 121.

In the present embodiment, as shown in FIG. 13, a left opening 112L is formed on the left side wall of ice making case 111 on the left side of ice making tray 120, ice making plate 121 or

cover members

122L, 122R. The As a result, introduction of cold air into the ice making case 111 is promoted, and the ice tray 121 is easily cooled. A cover 113L is formed on the upper side of the left opening 112L so as to face the inside of the ice making case 111 and obliquely downward. Thus, when water is supplied to the ice tray 121, the water is configured not to jump out of the left opening 112L.

Similarly, a right opening 112R is formed on the right side of the ice making case 111 on the right side of the ice making tray 120, the ice making tray 121, or the

cover members

122L and 122R. Thereby, the ice tray 121 is configured to be easily cooled. A cover 113 R is formed on the upper side of the right opening 112 R toward the inside of the ice making case 111 and obliquely downward. Thus, when water is supplied to the ice tray 121, the water is configured not to jump out of the right opening 112R.

Next, a configuration for attaching the ice making unit 100 to the door 210 of the refrigerator 200 will be described. Referring to FIG. 14, in the present embodiment, locking
