The cutlery basket 100, which accommodates various kinds of tableware, such as spoons, chopsticks, knives, forks, etc. may be detachably mounted to the cutlery baskets (14 a, 14 b). The cutlery basket 100 arranges cutlery such as spoons and chopsticks in the wash tub 12, so that the dishwasher can wash the cutlery.
The cutlery basket 100 may include a basket body 110.
The basket body 110 is formed to have a predetermined length corresponding to the length of a cutlery item, and includes a wash space 112 capable of accommodating the cutlery item, such as spoons or chopsticks, for example, therein. A plurality of holes 114 is formed in the basket body 110, so that wash water sprayed from the spray units in the wash tub 12 can be introduced or discharged to wash the cutlery accommodated in the basket body 110.
An opening 110 a through which the cutlery or the like can be put in and drawn out of the basket body 110 is formed, and the wash space 112 in which the cutlery received through the opening 110 a can be seated may also be contained in the cutlery basket 100.
A handle 120 may be provided at the basket body 110, such that a user who grasps the handle 120 can move the basket body 110.
The basket body 110 may further include a compartment plate 116. The compartment plate 116 divides the wash space 112 into a plurality of spaces, so that cutlery utensils to be accommodated in the cutlery basket 100 are classified and disposed in the divided spaces. The compartment plate 116 may be integrated with the basket body 110, or may be separated from the basket body 110 so that the compartment plate 116 can be detachably connected to the basket body 110.
The cutlery basket 100 may include distribution units 130.
The distribution units 130 may be configured in a manner that the cutlery utensils can be distributed and disposed in the basket body 110.
The distribution units 130 may be integrated with the basket body 110, or may also be configured separately from the basket body 110.
The distribution units 130 are disposed in a convex form toward the interior of the basket body 110 on the bottom surface 118 of the basket body 110 in such a manner that a plurality of cutlery utensils are distributed in the wash space 112.
The distribution units 130 are arranged in such a manner that cutlery utensils disposed in the basket body 110 are distributed between a first region (a1) of the bottom surface 118 of the basket body 110 and a second region (a2) provided in the first region (a1). The distribution units 130 may be disposed in a convex form toward the interior of the basket body 110 on the basis of the bottom surface 118 of the basket body 110.
The first region (a1) and the second region (a2) may be divided by the distribution units 130. In addition, the first region (a1) may enclose the second region (a2). That is, each distribution unit 130 is enclosed by the first region (a1) in which cutlery is disposed, so that the cutlery arranged in the basket body 110 can be distributed in a radial shape. In other words, the distribution units 130 may be disposed at the center of the bottom surface 118 of the basket body 110 in such a manner that the cutlery arranged in the basket body 110 can be distributed in a radial shape. However, arrangement of the distribution units 130 and arrangement or shape of the first and second regions (a1, a2) divided by the arrangement of the distribution units 130 are not limited thereto.
The distribution units 130 are disposed in the basket body 110, and a plurality of holes 138 may be arranged in a manner that wash water can pass through the holes 138.
Each distribution unit 130 may include an inclined surface 132.
The inclined surface 132 is inclined at a predetermined angle with respect to the bottom surface 118 of the cutlery basket 100, so that cutlery disposed in the cutlery basket 100 slides along the inclined surface 132 and is thus seated in the first region (a1). A plurality of cutlery utensils can be distributed without unbalance by the inclined surface 132.
The inclined surface 132 is formed to be inclined in a manner that the cutlery arranged in the basket body 110 is guided to the first region (a1). The inclined surface 132 may have a planar surface or a curved surface. As shown in the embodiment, the inclined surface 132 may have a planar surface or a curved surface. In addition, a cross-section perpendicular to the length direction of the distribution units is configured in the form of a close loop, so that the cutlery utensils can be distributed in a radial form on the basis of the distribution units disposed in the wash space. Although there is no limitation in the shape of the distribution units 130, each distribution unit may be formed to have a cone shape.
Although the inclined surface 132 may be formed to have different inclined angles (θ) according to the height of each distribution unit 130, the embodiment exemplarily shows the inclined surface 132 having the same angle according to the height of the distribution unit 130.
Each of the distribution unit 130 may further include a head portion 134.
The head portion 134 may be disposed at an upper end of the distribution unit 130, and may be enclosed by the inclined surface 132.
That is, the inclined surface 132 may be disposed among the head portion 134, the basket body 110, and the bottom surface 118.
Each of the distribution units 130 may further include a separation protrusion 136.
The separation protrusion 136 may be located below each distribution unit 130, such that the inclined surface 132 can be spaced apart from the bottom surface 118 of the basket body 110. Although wash water can be drained through a plurality of holes 114 on the bottom surface 118 of the basket body 110, if the inclined surface 132 is in contact with the bottom surface 118, wash water may be collected in the contact part and the inclined surface 132 and the bottom surface 118 are spaced apart from each other, so that wash water can be prevented from being collected in the contact part.
Each of the distribution units 130 may further include a movable handle 140 provided thereon, such that the user who uses the movable handle 140 can seat the distribution units in the basket body 110 or can detach the distribution units from the basket body 110.
FIGS. 6 and 7 are cross-sectional views illustrating a cutlery basket for a dishwasher according to an embodiment of the present disclosure.
An inclined angle (θ) between the inclined surface 132 and the bottom surface 118 of the basket body 110 may be formed in a manner that cutlery leaned to the inclined surface 132 is spaced apart from an upper end of the basket body 110 when one end of the cutlery is disposed in the first region (a1). In other words, a distance between the head portion 134 located at the height (h) of the distribution unit 130 and the bottom surface 118 may be larger than a half of an inner depth (d) of the basket body 110.
Because the inclined angle (θ) or the height of the distribution unit 130 is achieved, the size of a contact region between the cutlery and the basket body 110 can be minimized, and a surface area of wash water can be enlarged in size, resulting in increased washing efficiency. Through the above-mentioned construction, when one end of the cutlery is arranged in the first region (a1), at least some parts located in a longitudinal direction of the cutlery are not in contact with the basket body 110, so that the cutlery can be exposed to wash water.
FIG. 8 is a structural view illustrating a cover unit of a cutlery basket for a dishwasher according to an embodiment of the present disclosure. FIG. 9 exemplarily illustrates that a plurality of cutlery utensils are contained in a cutlery basket for the dishwasher according to an embodiment of the present disclosure.
Referring to FIGS. 8 and 9, the cutlery basket 100 may include a cover unit 150.
The cover unit 150 is constructed in a manner that cutlery arranged in the basket body 110 does not adhere closely to the basket body 110, and may also be disposed in the opening 110 a.
The cover unit 150 may include a cover body 152 and a separation member 154.
The cover body 152 may be disposed in the opening 110 a of the basket body 110. The cover body 152 forms an insertion hole 152 a coupled to the opening 110 a, and is formed to correspond to an upper shape of the basket body 110. That is, the cover body 152 may have a frame shape to correspond to the upper shape of the basket body 110 along a peripheral part of the opening 110 a.
Although the cover body 152 may be integrated with the basket body 110, it should be noted that the cover body 152 may be rotatably provided while being separated from the basket body. In more detail, a rotation unit 153 is provided at one side of the cover body 152, so that the rotation unit 153 can be rotated around the basket body 110. Through the above-mentioned construction, cutlery utensils can be put in and drawn out of the cutlery basket, resulting in greater convenience for the user. In addition, respective constituent elements of the cutlery basket 100 can be separated from each other when the cutlery basket 100 is washed, so that the constituent elements can be more cleanly washed.
The separation member 154 is provided to separate cutlery utensils from the basket body 110. In more detail, the separation member 154 is provided in the cover body 152, so that the cutlery utensils can be separated from the upper end corresponding to the opening 110 a of the basket body 110. The separation member 154 may be protruded toward the inside of the insertion hole 152 a of the cover body 152 or toward the inside of the opening 110 a. There may be a plurality of separation members 152 arranged along the cover body 152.
The separation member 152 may include a convex unit 156 that is convex toward the inside of either the insertion hole 152 a or the opening 110 a. The convex unit 156 may be provided to reduce the size of a contact region between the separation member 154 and the cutlery. If the cutlery utensils are randomly disposed in the basket body 110, the cutlery utensils disposed in the basket body 110 are in close contact with an inner surface of the basket body 110, so that a region to be washed by wash water is relatively reduced in size. In order to prevent reduction of the size of the region washed by wash water, the separation member 154 is constructed in a manner that the cutlery utensils are put in the basket body 110, and the cutlery utensils are point-contacted with the convex unit 156. As a result, the size of a contact region can be greatly reduced as compared to other cases in which the cutlery utensils are line-contacted or surface-contacted with the basket body 110, so that a relatively larger number of cutlery utensils can be exposed to the wash water.
The cover unit 150 may include a holder groove 158.
The holder groove 158 is provided to correspond to the separation member 154, and some parts of the cutlery utensils can be caught, or held, in the holder groove 158. As a result, the present disclosure prevents the occurrence of overlapping cutlery utensils, so that it can also prevent the washing efficiency from being decreased.
The holder groove 158 is disposed between one of the separation members 154 and a neighbor separation member 154 contiguous to the one separation member, and may be formed to be concave toward the cover body 152 rather than the separation member 154. There may be a plurality of holder grooves 158 in correspondence with the plurality of separation members 154, and the plurality of holder grooves 158 may be formed alternately with the plurality of separation members 154.
Although there is no limitation in the shape of the separation member 154, it should be noted that the plurality of separation members 154 and the plurality of holder grooves 158 according to the embodiments are formed alternately to make a wave shape.
In the case of the above-mentioned distribution units 130, the cutlery utensils are arranged parallel to one another along the first region (a1). The cutlery utensils are caught in the holder groove 158, or are point-contacted by the separation member 154, so that the cutlery utensils can be separated from each other and a surface region exposed to wash water can be increased in size.
A cutlery basket for a dish washing machine according to an embodiment of the present disclosure will hereinafter be described.
A detailed description of the same constituent elements as those described above will herein be omitted for convenience of description.
FIG. 10 exemplarily illustrates a distribution unit of the cutlery basket for the dishwasher according to an embodiment of the present disclosure. FIG. 11 is a cross-sectional view illustrating the distribution unit of the cutlery basket for the dishwasher according to an embodiment of the present disclosure.
The distribution unit 230 is formed to be convex toward the inside of the basket body 110 from the bottom surface of the basket body 110. A plurality of cutlery utensils may be distributed in the wash space 112.
The distribution unit 230 is disposed in the basket body 110, and may include a plurality of holes 238 through which wash water can pass.
The distribution units 230 may include an inclined surface 232.
The inclined surface 232 is obliquely formed in a manner that the cutlery utensils disposed in the basket body 210 are directed to the first region (a1). The inclined surface 232 may have a planar or curved shape. In the embodiment of the present disclosure, the inclined surface 232 may have planar and curved shapes. The first shape (a1) may enclose the second region (a2). That is, the distribution unit 230 is enclosed by the first region (a1) in which the cutlery utensils are arranged, so that the cutlery utensils disposed in the basket body 110 can be distributed in a radial form.
The distribution unit 230 may include an inclined surface 232 having an inclined angle changing with the height. In more detail, the degree of slope (α) of a first point on the inclined surface 232 is less than the degree of slop (β) of a second point located blow the first point. As a result, the plurality of cutlery utensils can be more efficiently distributed in a radial form.
As is apparent from the above description, the cutlery basket and the dish washing machine having the same can distribute a plurality of cutlery utensils, and can increase a surface area to be used for spraying of wash water, resulting in increased washing efficiency.
Although a few embodiments of the present disclosure have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the disclosure, the scope of which is defined in the claims and their equivalents.
