[0044] FIG. 1 is a perspective view showing the door of a dishwasher according to an embodiment of the present invention with the door open.

[0045] As illustrated in the drawing, a dishwasher (1) according to an embodiment of the present invention may have an exterior formed by a main body (10) and a door (20). The main body (10) may include a washing tank (11) in which a washing space for washing dishes is formed inside. In addition, the main body (10) may form the exterior of the dishwasher (1), and may have different configurations depending on the installation state, such as a freestanding type or a built-in type.

[0046] The above door (20) can open and close the washing tank (11) with an open front. The lower part of the door (20) is rotatably connected to the front of the main body (10) to open and close the washing tank (11).

[0047] The above washing tank (11) forms a washing space (110) where dishes are washed, and can be formed in a box shape with an open front, and can occupy most of the interior area of ​​the main body (10).

[0048] The washing tank (11) may be formed of stainless steel, and a rack (31, 32) for storing dishes may be arranged so as to be removable. The rack (31, 32) may be formed in a basket shape in which a plurality of wires intersect, so as to facilitate the washing of the stored dishes. The racks (31, 32) may be formed in various shapes, and a plurality of them may be arranged vertically. For example, the racks (31, 32) may be composed of a lower rack (31) and an upper rack (32).

[0049] Rails (12) may be provided on both left and right sides of the washing tank (11), and the rails (12) may be connected to the upper rack (32) or the lower rack (31) so that the upper rack (32) and the lower rack (31) may be extended or lowered. For example, the upper rack (32) may be extended or lowered along the rail (12), and the lower rack (31) may be extended or lowered along the rear side of the door (20).

[0050] A plurality of nozzles (14, 15) for spraying water for washing dishes may be arranged inside the washing tank (11). For example, the nozzles (14, 15) may be arranged between the upper and lower surfaces of the washing tank (11) and the racks (31, 32) arranged vertically. Accordingly, dishes stored inside the racks (31, 32) may be washed by the washing water sprayed in the vertical direction from the plurality of nozzles (14, 15).

[0051] A sump (13) may be provided at the bottom of the washing tank (11).

[0052] And, the sump (13) may be equipped with a circulation pump for circulating the washing water. The circulation pump may suck the water in the sump (13) and discharge it toward the nozzles (14, 15). Therefore, by the operation of the circulation pump, the water in the sump (13) is continuously supplied to the nozzles (14, 15), thereby enabling the circulation and spraying of the washing water. And, a drainage part through which the water in the sump (13) is drained may be equipped on the other side of the sump (13). Therefore, the washing water can be drained through the drainage part during or after the washing operation is completed. To this end, a flow path for the washing water may be configured between the sump (13), the circulation pump, the nozzles (14, 15), and the drainage part. And, the main body (10) may be equipped with a heat pump or a heater to enable heating of the washing water and the washing tank.

[0053] Hereinafter, the structure of the rack (32) and the accessory (40) will be described in detail with reference to the drawings. The accessory (40) can be mounted on both the upper rack (32) and the lower rack (31), but for convenience of explanation, the accessory (40) will be described below as being mounted on the upper rack (32) as an example. In addition, the upper rack (32) may be referred to as a rack (32) hereinafter.

[0054] Figure 2 is a perspective view of a rack equipped with accessories according to an embodiment of the present invention.

[0055] As illustrated, the rack (32) may have a mesh-shaped basket structure formed by a plurality of wires. For example, the wires may be formed of a metal material, and may be formed of a stainless steel material.

[0056] The above wire may include a main wire (321) forming the upper circumference of the rack (32). In addition, a plurality of horizontal wires (322) and vertical wires (323) may be provided to cross between the main wires (321). The horizontal wires (322) and vertical wires (323) may be continuously arranged in multiple numbers and spaced apart from each other to form a lattice-shaped mesh structure. In addition, the horizontal wires (322) and vertical wires (323) may have both ends bent upward and connected to the main wire (321), thereby forming a shape such as a basket. In addition, the horizontal wires (322) and vertical wires (323) may be bent into various shapes to suit the type and shape of dishes stored in the rack (32). The wires may also be in the form of thick rods or bars.

[0057] In addition, a guide member (33) may be formed on both left and right sides of the rack (32). The guide member (33) may be formed of a plastic material and may be coupled to the main wire (321), and may be exposed to the outer surfaces of the left and right sides of the rack (32).

[0058] The above guide member (33) can be coupled with the rail (12) to allow the rack (32) to move forward and backward. To this end, the guide member (33) may be provided with a plurality of rollers. In addition, the guide member (33) can be moved up and down while coupled with the rack (32), and the gap with the lower rack (31) or the space above the rack (32) can be adjusted.

[0059] A cup mounting member (35) may be provided on both left and right sides of the above rack (32). The cup mounting member (35) may be rotatably mounted on both left and right sides of the rack (32). The cup mounting member (35) may be unfolded from the side of the rack (32) by rotation, and may provide a space for mounting tableware (3), such as a cup.

[0060] A front cover (34) may be provided at the front end of the rack (32). The front cover (34) may be formed along the main wire (321) forming the front end of the rack (32). In addition, both ends of the front cover (34) may extend to the rear end and be connected to the guide member (33).

[0061] The front cover (34) may be formed of a plastic material and may be formed to wrap around the main wire (321). Accordingly, the front upper portion of the rack (32) on which the front cover (34) is formed becomes thicker than the main wire (321) and may be used as a handle when a user pulls out or inserts the rack (32).

[0062] In addition, a middle nozzle (15) that is drawn in and out together with the rack (32) is provided at the bottom of the rack (32), and water sprayed upward from the middle nozzle (15) can pass through the rack (32) and wash dishes stored in the rack (32).

[0063] Meanwhile, an accessory (40) may be mounted on the rack (32). The accessory (40) can store silverware (2) such as spoons, forks, knives, etc., and is mounted on the upper portion of the rack (32) and can be moved left and right to be mounted at a desired location. For example, the accessory (40) may have a structure suitable for storing the knife, and thus, the accessory (40) may be called a knife rack.

[0064] In addition, the accessory (40) can be mounted on the main wire (321). The front and rear ends of the accessory (40) can be mounted on the main wire (321) forming the front upper part and the rear upper part of the rack (32). To this end, the front-to-rear length of the accessory (40) can be formed to be equal to or slightly larger than the front-to-rear length of the rack (32).

[0065] A storage portion (410) may be formed on the upper surface of the above-mentioned accessory (40) in which small tableware (2) such as spoons, forks, knives, etc. can be placed. The storage portion (410) may form a sunken space and provide a space in which the tableware (2) can be placed. For example, the storage portion (410) may be opened in a grid shape so that water sprayed from below can pass through.

[0066] The front and rear ends of the above accessory (40) can be extended in the vertical direction so that the storage portion (410) can be sufficiently spaced from the top of the rack (32). Accordingly, the above accessory (40) can have a structure and shape that can secure a space for placing dishes on the rack (32) when mounted, and minimize interference with dishes placed on the rack (32).

[0067] For example, the above accessory (40) can be injection-molded with a plastic material to implement a three-dimensional shape.

[0068] Below, the structure of the above accessory (40) will be examined in more detail with reference to the drawings.

[0069] Fig. 3 is a perspective view of the above accessory. Fig. 4 is a plan view of silverware placed on the above accessory.

[0070] As illustrated, the accessory (40) may include a frame (41) in which a storage portion (410) is formed, and a supporter (42) extending downward from the front and rear ends of the frame (41).

[0071] The above frame (41) forms the upper part of the accessory (40) and can form a space in which tableware such as the silverware (2) is placed. The frame (41) can form the perimeter of the storage part (410). In addition, the frame (41) can protrude upwards more than the storage part (410). The frame (41) can be formed in a rectangular frame shape when viewed from above. For example, the frame (41) can include a pair of first side parts (411) that form left and right outer surfaces and extend in the front-back direction, and a pair of second side parts (412) that form front-back outer surfaces and connect the front and rear ends of the pair of first side parts (411). The first side part (411) can be referred to as a side part, and the second side part (412) can be referred to as a front part and a rear part.

[0072] The length of the accessory (40) may be determined by the first side portion (411) and may correspond to the front-back length of the rack (32). In addition, the width of the accessory (40) may be determined by the second side portion (412) and may have a smaller width than the length of the accessory (40). For example, the width of the accessory (40) may be smaller than half of the left-right length of the rack (32). Therefore, the accessory (40) may be positioned at any left-right position of the rack (32) so as not to interfere with dishes placed on the rack (32).

[0073] Meanwhile, the frame (41) may further include a corner portion (413). The corner portion (413) connects the end of the first side portion (411) and the end of the second side portion (412), and may be formed in an inclined or rounded shape.

[0074] The shape of the corner portion (413) can prevent interference or snagging between the accessory (40) and other components. For example, the shape of the corner portion (413) can allow the accessory (40) to move and naturally reposition itself when the corner portion (413) comes into contact with the main body or other components during the insertion or withdrawal process of the rack (32).

[0075] Meanwhile, the supporter (42) may form the front and rear sides of the accessory (40). In addition, the supporter (42) may be mounted on the rack (32). The supporter (42) may extend downward from the front and rear ends of the frame (41). At this time, a pair of the supporters (42) may be formed in the same shape. That is, the accessory (40) may be formed to be symmetrical with respect to the center in the front-rear direction.

[0076] The supporter (42) may extend downward from the second side portion (412). The supporter (42) may be formed integrally with the second side portion (412). That is, the upper end of the supporter (42) may form the second side portion (412), in which case the supporter (42) may become a part of the frame (41).

[0077] In addition, the supporter (42) can be extended in the vertical direction so that the storage portion (410) can be positioned upwards by a set distance from the rack (32). In addition, the lower end of the supporter (42) can be mounted on the upper end of the rack (32). For example, the front supporter (42) can be mounted on the front cover (34), and the rear supporter (42) can be mounted on the main wire (321).

[0078] For example, the supporter (42) may include an outer supporter (421) and an inner supporter (43). The outer supporter (421) may form the front and back of the supporter (42) and the accessory (40). The outer supporter (421) may include an extension portion (422) extending downward from both left and right sides of the front end of the frame (41).

[0079] The outer supporter (421) may further include a mounting portion (423). The mounting portion (423) provides a surface that is mounted on the upper end of the rack (32) and may connect the lower ends of the extension portions (422) on both sides. In addition, the mounting portion (423) may form the lower end of the outer supporter (421).

[0080] In addition, the opening (420) may be formed in the outer supporter (421). The lower end of the opening (420) may be formed by the mounting portion (423). Therefore, the support state of the supporter (42) and the rack (32), i.e., the exact mounting state of the accessory (40), may be confirmed through the opening (420).

[0081] The above supporter (42) may further include an inner supporter (43). The inner supporter (43) may be provided in pairs on the left and right sides of the supporter (42), and may extend in the vertical direction from a position closer to the center of the frame (41) than the outer supporter (421).

[0082] The inner supporter (43) may form the lower end of the supporter (42) together with the mounting portion (423). The inner supporter (43) may come into contact with the ground together with the lower end of the outer supporter (421) when the accessory (40) is separated from the rack (32) and placed independently. Therefore, the inner supporter (43) may also be referred to as a leg.

[0083] In addition, a fixing groove (435) is formed at the bottom of the inner supporter (43) so that the upper end of the rack (32) can be inserted and fixed. When the accessory (40) is mounted, the upper end of the rack (32) can be accommodated within the fixing groove (435), and stable mounting and fixing of the accessory (40) can be ensured.

[0084] Meanwhile, a storage portion (410) for storing silverware (2) may be formed in the inner region of the frame (41). The storage portion (410) may include a plurality of vertical ribs (44) and horizontal ribs (45). The vertical ribs (44) and horizontal ribs (45) may be arranged to intersect each other so that the bottom of the storage portion (410) may be formed in a plurality of grid shapes. In addition, the washing water may be configured to easily pass through and drain through a plurality of openings formed by the intersection of the vertical ribs (44) and horizontal ribs (45).

[0085] At this time, the vertical rib (44) is arranged parallel to the first side portion (411), and a plurality of vertical ribs can be formed at regular intervals in the left and right lateral directions. In addition, both ends of the vertical rib (44) can be connected to the second side portion (412).

[0086] The above-mentioned horizontal rib (45) is arranged parallel to the second side portion (412) and may be formed at regular intervals in the front-back direction. In addition, the horizontal rib (45) may extend to intersect the vertical rib (44). Therefore, the overall grid shape of the storage portion (410) may be formed by the horizontal rib (45) and the vertical rib (44). In addition, both ends of the horizontal rib (45) may be connected to the first side portion (411).

[0087] Both ends of the vertical rib (44) and the horizontal rib (45) can be bent upward. Accordingly, the storage portion (410) can be positioned lower than the frame (41). That is, the frame (41) functions as a border that protrudes upward along the perimeter of the storage portion (410), thereby allowing the tableware (2) placed in the storage portion (410) to remain stably seated without falling.

[0088] Meanwhile, the storage unit (410) may include a first loading unit (401) at the front and a second loading unit (402) at the rear based on a horizontal rib (451) arranged in the center. The first loading unit (401) and the second loading unit (402) may be configured to allow the silverware (2) to be placed separately from one accessory (40).

[0089] For example, the first loading part (401) and the second loading part (402) may be positioned to face each other based on the center of the storage part (410). In addition, the first loading part (401) and the second loading part (402) may each include a plurality of alignment parts (49) that enable the silverware (2) to be stored in an aligned state. In detail, among the entire horizontal ribs (45), the alignment parts (49) are not formed on the horizontal rib (451) formed at the center of the storage part (410) and the horizontal ribs (453) at the front and rear ends, and the alignment parts (49) may be formed on the remaining horizontal ribs (492).

[0090] The alignment portion (49) may have a plurality of alignment grooves (490) formed continuously along the horizontal rib (452). Accordingly, one silverware (2) may be placed in each of the alignment grooves (490), and the plurality of silverware (2) may be mounted in a separated state without overlapping. In addition, the alignment grooves (49) may be formed to have directionality, so that the silverware (2) mounted in the plurality of alignment grooves (490) may be aligned and mounted while being tilted in the same direction.

[0091] For example, the alignment portion (49) may be formed on a plurality of horizontal ribs (452), and may be formed on each of the first loading portion (401) and the second loading portion (402). In addition, the alignment portions (49) formed on each of the horizontal ribs (452) may be formed in different shapes.

[0092] In addition, the alignment grooves (464a, 474a, 483a) formed in the first loading section (401) can be arranged in multiple rows, and each row can be arranged on the same extension line (Lva). Accordingly, the silverware (2) can be independently seated in the multiple alignment grooves (464a, 474a, 483a) positioned on the same extension line (Lva), and do not overlap with the neighboring silverware (2).

[0093] In addition, the alignment grooves (464b, 474b, 483b) formed in the second loading section (402) can also be arranged in multiple rows, and each row can be arranged on the same extension line (Lvb). Accordingly, the silverware (2) mounted on the second loading section (402) can also be independently mounted on the multiple alignment grooves (464b, 474b, 483b) positioned on the same extension line (Lvb), and do not overlap with the neighboring silverware (2).

[0094] Meanwhile, the alignment grooves (464b, 474b, 483b) formed in the second loading section (402) may not be arranged on the same extension line as the alignment grooves (464a, 474a, 483a) of the first loading section (401), but may be arranged on extension lines (Lva, Lvb) that are parallel to each other.

[0095] Accordingly, the silverware (2) mounted on the first loading section (401) and the second loading section (402) are independently mounted on a plurality of alignment grooves (490) positioned on the same extension line (Lva, Lvb) so as not to overlap with the neighboring silverware (2). In addition, the silverware (2) mounted on the first loading section (401) can be arranged in parallel with the silverware (2) mounted on the second loading section (402) without overlapping with each other.

[0096] For example, as illustrated in FIG. 4, the silverware (2) may be a knife, and may be placed in the first loading section (401) and the second loading section (402), respectively. At this time, the knife may be placed so that the handle portion faces the front and rear ends of the storage section (410), and the blade portion faces the center of the storage section. At this time, the blades may be seated in the alignment grooves (464a, 474a, 483a) of the first loading section (401) and the alignment grooves (464b, 474b, 483b) of the second loading section, which are arranged parallel to each other, so that they may be alternately placed without overlapping each other.

[0097] Below, the structure of the alignment parts (49) constituting the loading part (401, 402) will be examined in more detail with reference to the drawings.

[0098] Fig. 5 is a drawing showing the arrangement of the first loading section and the second loading section of the above-described accessory. Furthermore, Fig. 6 is a partial perspective view showing the arrangement of the alignment sections formed in the first loading section and the second loading section. Furthermore, Fig. 7 is an enlarged view of section A of Fig. 6 and a drawing showing the shapes of the alignment sections.

[0099] As illustrated, a plurality of alignment portions (49) may be formed in the first loading portion (401) and the second loading portion (402). In addition, the plurality of alignment portions (49) and alignment grooves (490) arranged in the first loading portion (401) and the second loading portion (402) may have the same structure with only a difference in position. Accordingly, the silverware (2) may be arranged in the first loading portion (401) and the second loading portion (402), respectively.

[0100] In addition, the extension lines (Lv) of the alignment grooves (464a, 474a, 483a) formed in the first loading section (401) and the vertical extension lines (Lv) of the alignment grooves (464a, 474a, 483a) formed in the second loading section (402) can be formed parallel to each other. That is, the alignment grooves (464a, 474a, 483a) of the first loading section (401) and the alignment grooves (464b, 474b, 483b) of the second loading section (402) are not positioned on the same line. Accordingly, the silverware (2) placed in the first loading section (401) and the second loading section (402) do not overlap each other.

[0101] In addition, the first loading unit (401) and the second loading unit (402) may each include a first alignment unit (46a, 46b) and a second alignment unit (47a, 47b). In addition, the first loading unit (401) and the second loading unit (402) may further include a third alignment unit (48a, 48b).

[0102] In detail, the first loading section (401) may be positioned in the front part of the entire receiving section (410). In addition, the first loading section (401) may include a first alignment section (46a). The first alignment section (46a) may be formed on at least one of the horizontal ribs (452). For example, the first alignment section (46a) may be formed on three horizontal ribs (452) among the entire horizontal ribs (45) of the first loading section (401). In addition, it may be formed on the first, fifth, and eighth horizontal ribs (452) forward from the horizontal rib (451) at the center of the receiving section (410).

[0103] The above first alignment portion (46a) is formed to protrude upward along the horizontal rib (45), and a plurality of first alignment grooves (464a) and first section protrusions (461a) can be formed continuously.

[0104] In detail, the first alignment groove (464a) may be formed by being recessed at the top of the first alignment portion (46a). In addition, first partition protrusions (461a) may further protrude upward on both sides of the first alignment groove (464a). That is, the first alignment groove (464a) may be formed between a pair of first partition protrusions (461a). In addition, the first partition protrusions (461a) may protrude upward at a height that is higher than the top of the first alignment groove (464a) and lower than the top of the frame (41).

[0105] Meanwhile, the first alignment groove (464a) can be accommodated internally at the bottom of the silverware (2). In addition, the first alignment groove (464a) can be formed in a shape that can induce the silverware (2) to be aligned while tilted in one direction while accommodated in the first alignment groove (46a).

[0106] In detail, the first alignment groove (464a) may be formed by a first inclined surface (462a) and a second inclined surface (463a). The first inclined surface (462a) and the second inclined surface (463a) may be formed in a shape that becomes narrower as it goes downward. In addition, the lower ends of the first inclined surface (462a) and the second inclined surface (463a) may be in contact with each other, and the portion where the first inclined surface (462a) and the second inclined surface (463a) are in contact may be formed to be eccentric from the center between the adjacent first section protrusions (461a).

[0107] For example, the slope of the first inclined surface (462a) may be formed smaller than the slope of the second inclined surface (463a). In addition, based on the overall width (W) of the first alignment groove (464a), the width (W1) of the first inclined surface (462a) may be formed larger than half of the overall width (W). In addition, the width (W1) of the first inclined surface (462a) may be formed larger than the width (W2) of the second inclined surface (463a). In addition, an extension line (Lv) connecting the points where the lower ends of the first inclined surfaces (462a) and the second inclined surfaces (464a) of the plurality of first alignment grooves (464a) meet may be arranged to be eccentric from the center of the overall width (W) of the first alignment groove (464a). That is, the shape of the first alignment groove (464a) can be formed into an asymmetrical shape.

[0108] In addition, the angle (α1) of the first inclined surface (462a) may be formed smaller than the angle (α2) of the second inclined surface (463a) with respect to the horizontal plane passing through the point where the first inclined surface (462a) and the second inclined surface (463a) meet each other. That is, the first inclined surface (462a) may have a gentler slope compared to the second inclined surface (463a).

[0109] Accordingly, when the silverware (2) is settled in the first alignment groove (464a), the lower end of the silverware (2) is positioned at the portion where the first inclined surface (462a) and the second inclined surface (463a) come into contact with each other. Then, the silverware (2) is tilted by the shaking of the accessory (40) or the silverware (2) due to the washing water irradiated in the washing space (110). At this time, the first inclined surface (462a) has a smaller incline and a larger width than the second inclined surface (463a), so that the silverware (2) can be naturally aligned by lying down in a form in contact with the first inclined surface (462a).

[0110] Meanwhile, a plurality of the first alignment grooves (464a) are continuously formed along the horizontal rib (45), and thus, each silverware (2) placed in each of the first alignment grooves (464a) can be aligned while lying in the same direction within the first alignment groove (464a). Accordingly, the silverware (2) placed within the storage portion (410) do not overlap each other, and thus can be maintained in a state in which they are easy to clean and dry.

[0111] The first loading section (401) may include a second alignment section (47a). The second alignment section (47a) may be formed on at least one of the horizontal ribs (45). For example, the second alignment section (47a) may be formed on one horizontal rib (45) among all horizontal ribs (45) of the first loading section (401). In addition, it may be formed on the third horizontal rib (45) forward from the horizontal rib (45) at the center of the receiving section (410). In addition, the second alignment section (47a) may be arranged between the first alignment sections (46a). In addition, the second alignment section (47a) may be arranged between the third alignment sections (48a). The first alignment portion (46a), the second alignment portion (47a), and the third alignment portion (48a) may be sequentially arranged on adjacent horizontal ribs (45).

[0112] The second alignment portion (47a) is formed to protrude upward along the horizontal rib (45), and a plurality of second alignment grooves (47a) and second partition protrusions (471a) can be formed continuously. The overall arrangement of the second alignment grooves (47a) and the second partition protrusions (471a) is similar to that of the first alignment portion (46a), but the specific shapes of the second alignment grooves (47a) and the second partition protrusions (471a) are somewhat different.

[0113] In detail, the second alignment groove (474a) may be formed by being recessed at the upper end of the second alignment portion (47a). In addition, a second partition protrusion (471a) may further protrude upward on both sides of the second alignment groove (474a). That is, the second alignment groove (474a) may be formed between a pair of second partition protrusions (471a). In addition, the second partition protrusion (471a) may protrude upward and may protrude higher than the upper end of the second alignment groove (474a). In addition, the second partition protrusion (471a) may protrude to a height corresponding to the upper end of the frame (41). In this case, the height of the second partition protrusion (471a) may be formed higher than the height of the first partition protrusion (461a). And, the protruding end of the second partition protrusion (471a) can be positioned on the same extension line (Lp) as the protruding end of the first partition protrusion (461a).

[0114] Meanwhile, the second alignment groove (474a) can be accommodated internally at the bottom of the silverware (2). In addition, the second alignment groove (474a) can induce the silverware (2) to be aligned while tilted in one direction while accommodated in the second alignment groove (474a).

[0115] In detail, the second alignment groove (474a) may be formed by a first inclined surface (472a) and a second inclined surface (473a). The first inclined surface (472a) and the second inclined surface (473a) may be formed in a shape that becomes narrower as it goes downward. In addition, the lower ends of the first inclined surface (472a) and the second inclined surface (473a) may be in contact with each other, and the portion where the first inclined surface (472a) and the second inclined surface (473a) are in contact with each other may be formed to be eccentric from the center between the adjacent second partition protrusions (471a). That is, the shape of the second alignment groove (474a) may be formed in an asymmetrical shape.

[0116] For example, the slope of the first inclined surface (472a) may be formed smaller than the slope of the second inclined surface (473a). In addition, based on the overall width (W) of the second alignment groove (474a), the width (W1) of the first inclined surface (472a) may be formed larger than half of the overall width (W). In addition, the width (W1) of the first inclined surface (472a) may be formed larger than the width (W2) of the second inclined surface (473a). In addition, the extension line (Lv) where the lower ends of the first inclined surface (472a) and the second inclined surface (473a) meet may be arranged to be eccentric from the center of the overall width (W). In addition, the point where the lower end of the first inclined surface (462a) and the second inclined surface (463a) of the first alignment groove (464a) meet and the point where the lower end of the first inclined surface (472a) and the second inclined surface (473a) of the second alignment groove (474a) meet can be located on the same extension line (Lv).

[0117] In addition, the angle (β1) of the first inclined surface (472a) may be formed smaller than the angle (β2) of the second inclined surface (473a) with respect to the horizontal plane passing through the point where the first inclined surface (472a) and the second inclined surface (473a) meet each other. That is, the first inclined surface (472a) may have a gentler slope compared to the second inclined surface (473a).

[0118] The first inclined surface (472a) and the second inclined surface (473a) formed in the second alignment groove (474a) are arranged in the same manner as the first inclined surface (462a) and the second inclined surface (463a) formed in the first alignment groove (464a), but their sizes and shapes may be somewhat different.

[0119] In detail, the angles (β1, β2) of the first inclined surface (472a) and the second inclined surface (473a) of the second alignment groove (474a) may be formed to be greater than the angles (α1, α2) of the first inclined surface (462a) and the second inclined surface (463a) of the first alignment groove (464a). Therefore, even when silverware (2) having partially different thicknesses is placed, the first alignment groove (464a) and the second alignment groove (474a) may provide a stable support structure and an alignment structure. For example, when the silverware (2) is a knife, the handle portion having a thick thickness may be aligned and placed in the first alignment groove (464a), and the blade portion having a relatively thin thickness may be aligned and placed in the second alignment groove (474a).

[0120] When the silverware (2) is settled in the second alignment groove (474a), the lower end of the silverware (2) is positioned at a portion where the first inclined surface (472a) and the second inclined surface (473a) come into contact with each other. Then, the silverware (2) is tilted by the shaking of the accessory (40) or the silverware (2) due to the washing water irradiated into the washing space (110). At this time, since the inclination of the first inclined surface (472a) is smaller than that of the second inclined surface (473a) and the width is larger, the silverware (2) can be aligned while naturally lying down in a form in contact with the first inclined surface (472a).

[0121] In addition, an extension rib (475a) extending upward along the second partition protrusion (471a) may be further formed on the upper ends of the first inclined surface (472a) and the second inclined surface (473a). The extension rib (475a) may protrude further than the outer surface of the second partition protrusion (471a) so that, when the silverware (2) is placed, the silverware (2) may be spaced apart from the second partition protrusion (471a) that is long vertically without directly contacting it. Accordingly, more space required for washing and drying the silverware (2) may be secured.

[0122] Meanwhile, the second alignment grooves (474a) are formed in a plurality of continuous manners along the horizontal rib (45), and thus, each silverware (2) placed in each second alignment groove (474a) can be aligned while lying in the same direction within the second alignment groove (474a). Accordingly, the silverware (2) placed within the storage portion (410) do not overlap each other, and thus can be maintained in a state in which they are easy to clean and dry.

[0123] In addition, the second alignment groove (474a) and the second partition protrusion (471a) may be arranged on the same extension line (Lv, Lp) as the first alignment groove (464a) and the first partition protrusion (461a), respectively. Accordingly, the silver wear (2) comes into contact with both the first alignment groove (464a) and the second alignment groove (474a), and may be mounted in an aligned state in the same direction.

[0124] The first loading section (401) may include a third alignment section (48a). The third alignment section (48a) may be formed on at least one of the horizontal ribs (45). For example, the third alignment section (48a) may be formed on four horizontal ribs (45) among all horizontal ribs (45) of the first loading section (401). In addition, the third alignment section (48a) may be formed on the second, fourth, sixth, and seventh horizontal ribs (45) forward from the horizontal rib (45) at the center of the receiving section (410). The third alignment section (48a) may be disposed between the first alignment section (46a) and the second alignment section (47a). In addition, the third alignment section (48a) may also be disposed between the first alignment sections (46a).

[0125] The third alignment portion (48a) is formed to protrude upward along the horizontal rib (45), and a plurality of third alignment grooves (483a) may be continuously formed on the third alignment portion (48a). The third alignment grooves (483a) may have a smaller size than the first alignment grooves (464a) and the second alignment grooves (474a). In addition, a plurality of third alignment grooves (483a) may be arranged between a pair of extension lines (Lp) connecting the first section protrusion (461a) and the second section protrusion (471a). That is, a plurality of third alignment grooves (483a) may be arranged within the same area as the first alignment groove (464a) and the second alignment groove (474a).

[0126] The third alignment groove (483a) may be formed by a first inclined surface (481a) and a second inclined surface (482a). The first inclined surface (481a) and the second inclined surface (482a) may be formed in a shape that becomes narrower as they go downward. In addition, the lower ends of the first inclined surface (481a) and the second inclined surface (482a) are in contact with each other.

[0127] For example, the slope (γ1) of the first inclined surface (481a) may be formed to be the same as the slope (γ2) of the second inclined surface (482a). Accordingly, the third alignment groove (483a) may not be involved in the alignment of the silverware (2), but may serve to prevent the flow of the silverware (2) and assist in maintaining the silverware (2) in a state where it is arranged on the first alignment groove (464a) and the second alignment groove (474a). For example, a thin part, such as a blade of the knife, may be inserted or caught in the third alignment groove (483a).

[0128] Meanwhile, the second loading unit (402) may be configured by a combination of alignment units (46a, 47a, 48a) of the first loading unit (401) and corresponding alignment units (46b, 47b, 48b). That is, the second loading unit (402) may include a first alignment unit (46b) and a second alignment unit (47b). In addition, the second loading unit (402) may further include a third alignment unit (48b). In addition, the shapes and arrangement structures of the first alignment unit (46b), the second alignment unit (47b), and the third alignment unit (48b) may be the same as the alignment units (46a, 47a, 48a) of the first loading unit (401) described above.

[0129] The second loading section (402) may include a first alignment section (46b). The first alignment section (46b) may be formed at a position symmetrical to the first alignment section (46a) of the first loading section (401) with respect to the horizontal rib (451) at the center of the receiving section (410). In addition, the shape of the first alignment section (46b) may be the same as the shape of the first alignment section (46a) of the first loading section (401) described above, and only the position thereof may be different. The first alignment section (46b) may include a plurality of first alignment grooves (464b) and first partition protrusions (461b). In addition, the first alignment grooves (464b) may include a first inclined surface (462b) and a second inclined surface (463b). And, that is, the shape of the first alignment groove (464b) can be formed in an asymmetrical shape. The first inclined surface (462b) can be formed to have a smaller incline than the second inclined surface (463b), thereby inducing one-way alignment of the silverware (2).

[0130] And, the second loading part (402) may include a second alignment part (47b). The second alignment part (47b) may be formed at a position symmetrical to the second alignment part (47a) of the first loading part (401) based on the horizontal rib (451) at the center of the receiving part (410). And, the shape of the second alignment part (47b) may be the same as that of the second alignment part (47a) of the first loading part (401) described above, except for the shape and position. The second alignment part (47b) may include a plurality of second alignment grooves (474b) and second partition protrusions (471b). And, the second alignment grooves (474b) may include a first inclined surface (472a) and a second inclined surface (473a). The first inclined surface (472a) may be formed to have a smaller incline than the second inclined surface (473a) to induce unidirectional alignment of the silverware (2). That is, the shape of the first alignment groove (474b) may be formed in an asymmetrical shape.

[0131] The first alignment groove (464b) and the second alignment groove (474b) constituting the second loading section (402) may be arranged on the same extension line (Lv). However, the extension line (Lv) of the first alignment groove (464b) and the second alignment groove (474b) of the second loading section (402) may not coincide with the extension line (Lv) of the first alignment groove (464a) and the second alignment groove (474a) constituting the first loading section (401) and may be arranged parallel to each other.

[0132] And, the second loading section (402) may include a third alignment section (48b). The third alignment section (48b) may be formed at a position symmetrical to the third alignment section (48b) of the first loading section (401) with respect to the horizontal rib (45) at the center of the receiving section (410), and its shape may also be formed identically. That is, the third alignment section (48b) may be composed of a first inclined surface (481b) and a second inclined surface (482b) having the same inclination.

[0133] Below, the operation of the dishwasher (1) having the above structure will be examined.

[0134] In order to effectively wash and dry the silverware (2), the rack (32) may be equipped with the accessory (40). Furthermore, the silverware (2) may be placed on the accessory (40) and washed. Furthermore, the accessory (40) may be mounted on the top of the rack (32).

[0135] When the above accessory (40) is mounted on the top of the rack (32), the supporters (42) at the front and rear ends of the accessory (40) can be respectively mounted on the front cover (34) at the front end of the rack (32) and the main wire (321) at the rear end.

[0136] And, the silverware (2) for washing can be placed in the storage section (410) of the rack (32). For example, the silverware (2) can be a knife, and can be placed in the first loading section (401) and the second loading section (402), respectively, as shown in FIG. 4.

[0137] The silverware (2) disposed in the first loading section (401) and the second loading section (402) can be placed in the respective alignment grooves (490). That is, the silverware (2) can be placed independently, one by one, without overlapping each other by the alignment grooves (46a, 47a, 48a) of the first loading section (401) disposed on the same extension line. In addition, the silverware (2) can be placed in a state of being aligned in one direction by the inclined surface structure formed in the alignment grooves (46a, 47a, 48a).

[0138] In addition, the silverware (2) can be independently arranged one by one without overlapping each other by the alignment grooves (46b, 47b, 48b) of the second loading part (402) arranged on the same extension line. In addition, the silverware (2) can be arranged in a state of being aligned in one direction by the inclined surface structure formed in the alignment grooves (46b, 47b, 48b).

[0139] At this time, the extension lines (Lv) of the alignment grooves (46a, 47a) constituting the first loading section (401) and the extension lines (Lv) of the alignment grooves (46b, 47b) constituting the second loading section (402) are arranged parallel to each other, and therefore, the silverware (2) placed on the first loading section (401) and the second loading section (402) do not overlap each other.

[0140] Accordingly, a plurality of silverware (2) are arranged within the storage section (410) without overlapping each other, and effective washing and drying operations can be performed.

[0141] Meanwhile, the present invention may have various other embodiments despite the aforementioned exceptions. Below, other embodiments of the present invention will be described in detail with reference to the drawings. Components not described below are identical to those of the aforementioned embodiments, and thus, to avoid redundancy, their detailed descriptions and illustrations may be omitted, and the same reference numerals may be used for description. In other words, below, only components that differ from the aforementioned embodiments will be described in detail.

[0142] Figure 8 is a drawing showing the shape of an alignment part according to a second embodiment of the present invention.

[0143] As illustrated, the dishwasher (1) according to the second embodiment of the present invention may be equipped with an accessory (40') arranged for washing the silverware (2). In addition, the structure of the accessory (40') is the same as that of the above-described embodiment, with only a slight difference in the structure of the alignment part (56).

[0144] The storage portion (410) of the above accessory (40') may be provided with a plurality of horizontal ribs (45), and alignment portions (56) may be arranged on at least some of the horizontal ribs (452) among the horizontal ribs (45). The alignment portions (56) may include a plurality of alignment grooves (565) and partition protrusions (561). The alignment grooves (565) may be continuously formed along the alignment portions (56) and may be arranged between a pair of partition protrusions (561).

[0145] The sunken shape of the alignment groove (565) may be formed so as to be eccentric to one side, rather than being symmetrical with respect to the center extension line (Lc) between the extension lines (Lp) passing through the partition protrusions (561) on both the left and right sides. Accordingly, the silverware (2) inserted into the alignment groove (565) may be aligned while tilted in one direction.

[0146] For example, the alignment groove (565) may include a first inclined surface (562), a second inclined surface (563), and a connecting portion (564). The first inclined surface (562) and the second inclined surface (563) form left and right sides of the inner surface of the alignment groove (565), and may be formed to be inclined so as to become closer to each other as they go downward. In addition, the connecting portion (564) may connect the lower ends of the first inclined surface (562) and the second inclined surface (563).

[0147] At this time, the slope of the first inclined surface (562) may be formed smaller than the slope of the second inclined surface (563) based on the horizontal line passing through the lower end of the alignment groove (565). In addition, the horizontal width of the first inclined surface (562) may be formed larger than the horizontal width of the second inclined surface (563). In addition, at least a portion of the first inclined surface (562) may extend past the center extension line (Lc) or to a position adjacent thereto. In addition, the first inclined surface (562) may be positioned on one side of the center extension line (Lc), and the connecting portion (564) and the second inclined surface (563) may be positioned on the other side.

[0148] Accordingly, when the silverware (2) is placed in the alignment groove (565), the silverware (2) can be tilted to come into contact with the first inclined surface (562), and can be aligned in a state in which it comes into contact with the first inclined surface (562). In addition, the silverware (2) can be aligned in the same direction in a plurality of alignment grooves (565) placed along the alignment portion (56).

[0149] In addition, the storage section (410) of the above-described accessory (40') may further be provided with alignment sections made up of alignment grooves of different sizes in a plurality of horizontal ribs (452) as in the above-described embodiment, and may have the same arrangement structure as in the above-described embodiment.

[0150] Figure 9 is a drawing showing the shape of an alignment part according to a third embodiment of the present invention.

[0151] As illustrated, the dishwasher (1) according to the third embodiment of the present invention may be equipped with an accessory (40'') arranged for washing the silverware (2). In addition, the structure of the accessory (40'') is the same as that of the above-described embodiment, and there is only a slight difference in the structure of the alignment part (66).

[0152] The storage section of the above accessory (40'') may be provided with a plurality of horizontal ribs (45), and alignment portions (66) may be arranged on at least some of the horizontal ribs (452) among the horizontal ribs (45). The alignment portions (66) may include a plurality of alignment grooves (665) and partition protrusions (661). The alignment grooves (665) may be continuously formed along the alignment portions (66) and may be arranged between a pair of partition protrusions (661).

[0153] The sunken shape of the alignment groove (665) may be formed so as to be eccentric to one side, rather than being symmetrical with respect to the center extension line (Lc) between the extension lines (Lp) passing through the partition protrusions (661) on both the left and right sides. Accordingly, the silverware (2) inserted into the alignment groove (665) may be aligned while tilted in one direction.

[0154] For example, the alignment groove (665) may include a first side portion (662), a second side portion (663), and a connection portion (664). The first side portion (662) and the second side portion (663) may form left and right sides of the inner surface of the alignment groove (665). The first side portion (662) and the second side portion (663) may extend in a direction intersecting the connection portion (664). The first side portion (662) and the second side portion (663) may extend perpendicularly to the connection portion (664).

[0155] The above connecting portion (664) can connect the lower ends of the first side portion (662) and the second side portion (663). In addition, the connecting portion (664) can be formed to have the same height from one end to the other end. In addition, the connecting portion (664) can extend parallel to the upper end of the alignment portion (66).

[0156] At this time, the first side portion (662) may be formed closer to the center extension line (Lc), which is the midpoint between the extension lines (Lp) passing through the partition protrusions (661) on both sides, than the second side portion (663). In addition, the connecting portion (664) may be formed to extend further toward the second side portion (663) based on the center extension line (Lc).

[0157] Accordingly, when the silverware (2) is placed in the alignment groove (665), the silverware (2) can be tilted to come into contact with the first side portion (662), and can be aligned in a state of coming into contact with the first side portion (662). In addition, the silverware (2) can be aligned in the same direction in a plurality of alignment grooves (665) placed along the alignment portion (66).

[0158] In addition, the storage section (410) of the above-described accessory (40'') may further be provided with an alignment section made up of alignment grooves of different sizes in a plurality of horizontal ribs (452) as in the above-described embodiment, and may have a layout structure as in the above-described embodiment.

[0159] Fig. 10 is a drawing showing the shape of an alignment part according to the fourth embodiment of the present invention.

[0160] As illustrated, the dishwasher (1) according to the fourth embodiment of the present invention may be equipped with an accessory (40''') arranged for washing the silverware (2). The structure of the accessory (40''') is the same as that of the above-described embodiment, with only a slight difference in the structure of the alignment part (76).

[0161] The storage portion (410) of the above accessory (40''') may be provided with a plurality of horizontal ribs (45), and an alignment portion (76) may be arranged on at least some of the horizontal ribs (452) among the horizontal ribs (45). The alignment portion (76) may include a plurality of alignment grooves (765) and partition protrusions (761). The alignment grooves (765) may be continuously formed along the alignment portion (76), and may be arranged between a pair of the partition protrusions (761).

[0162] The sunken shape of the alignment groove (765) may be formed so as to be eccentric to one side, rather than being symmetrical with respect to the center extension line (Lc) between the extension lines (Lp) passing through the partition protrusions (761) on both the left and right sides. Accordingly, the silverware (2) inserted into the alignment groove (765) may be aligned while tilted in one direction.

[0163] For example, the alignment groove (765) may have a rounded inner surface. In particular, the alignment groove (765) may have a shape in which the bottom is formed to be rounded, thereby inducing the silverware (2) to tilt in one direction.

[0164] In detail, it may include a first round portion (762), a second round portion (763), and a connecting portion (764). The first round portion (762) and the second round portion (763) may be formed to become closer to each other as they extend downward, and may be formed to be rounded with the same curvature.

[0165] In addition, the lower end of the first round portion (762) and the lower end of the second round portion (763) can be connected by the connecting portion (764). The connecting portion (764) can be formed in a round shape with the central portion being formed lowest. The first round portion (762), the second round portion (763), and the connecting portion (764) can be formed in an overall continuous round shape.

[0166] Meanwhile, the sunken central portion of the connecting portion (764) may be positioned at a position that is spaced to one side from the center extension line (Lc), which is the midpoint between the extension lines (Lp) passing through the partition protrusions (761) on both sides. In detail, the first round portion (762) may be positioned closer to the center extension line (Lc) than the second round portion (763). Accordingly, the alignment groove (765) may be formed at a position that is spaced to one side between the partition protrusions (761).

[0167] Accordingly, when the silverware (2) is placed in the alignment groove (765), the silverware (2) can be tilted to come into contact with the first round portion (762), and can be aligned in a state of coming into contact with the first round portion (762). In addition, the silverware (2) can be aligned in the same direction in a plurality of alignment grooves (765) placed along the alignment portion (76).

[0168] In addition, the storage portion (410) of the accessory (40) may further be provided with an alignment portion made up of alignment grooves of different sizes on a plurality of horizontal ribs as in the above-described embodiment, and may have a layout structure as in the above-described embodiment.

[0169] The washing machine according to the embodiment of the present invention has high industrial applicability because it guarantees washing and drying performance and improves storage efficiency.
