  However, the conventional tableware storage basket has the following problems.

  The upper basket 4 made of a conventional rod-shaped wire rod has a method in which the protrusions 14 arranged in the front and rear directions extending in the vertical direction are fan-shaped and tilted obliquely to the side.

  Generally, when the tableware 10 with a large curvature is also seen on the outer periphery side of the tableware 10, the positions of the wall surfaces of the tableware 10 with the small curvature and the tableware 10 are almost the same. Therefore, this method receives the support of the tableware 10 as wide as possible, and has various shapes such as a tableware with a large curvature, a tableware with a small curvature, a tableware with a large thickness, and a tableware with a small thickness. 10 is easily supported.

  However, in this method, since the protrusion 14 is extended on the fan and lengthened, the protrusion 14 extends in the front-rear direction, and the range in which the tableware 10 and the protrusion 14 overlap is increased as viewed from the nozzle 3 side. There has been a problem that the cleaning water ejected from the nozzle 3 below the upper basket 4 is easily blocked by the protrusions 14 and the cleaning performance is deteriorated.

  Further, in order to reduce the manufacturing cost of the upper basket 4 having the long protrusions 14, if the upper basket 4 is formed of resin, it is necessary to increase the thickness of the protrusions 14 in order to maintain the strength. If the thickness is increased, the washing water ejected from the nozzle 3 is further easily blocked by the protrusions 14, so the upper basket 4 having the long protrusions 14 cannot be formed of resin, and is formed of a rod-shaped wire. It had been.

  The present invention solves the above-described conventional problems, and provides a dish storage basket and a dishwasher that can easily set dishes having different sizes and shapes with an inexpensive configuration without deteriorating the cleaning performance. It is an object.

In order to solve the above-described conventional problems, a tableware storage basket according to the present invention has a substantially rod-shaped first support member having a plurality of concave grooves that support the lower end of tableware, and supports the tableware wall surface and the upper and lower sides.

The concave groove portion supports the lower end of the inner peripheral side of the tableware, and is above the second support member. Tableware can be set by supporting the upper wall on the outer peripheral side of the tableware by point contact at the tip of the projection part that is long in the downward direction. Moreover, if viewed on the outer peripheral side of the tableware, the tableware has a large curvature. However, the tableware with a small curvature can be easily set with various shapes because the wall surface of the tableware is almost the same. In addition, there is a gap between the first support member and the second support member, and since the tableware and the protrusion are in point contact, the protrusions found in a conventional rod-shaped wire rod basket are fanned out. As a result, the overlapping range of the tableware and the protrusion when viewed from the nozzle side is increased, and the cleaning water ejected from the nozzle on the lower surface of the basket is blocked by the protrusion, so that the problem of deteriorating the cleaning performance does not occur. Is. And even if it does not incline a protrusion part in the diagonal direction, there exists an effect equivalent to the protrusion part which spreads in the conventional fan shape. In addition, since it is not necessary to increase the thickness of the protruding portion in order to give strength, it is possible to configure the cage having the protruding portion with resin. Therefore, it is possible to provide a tableware storage basket in which tableware can be set without deteriorating cleaning performance and without cost.

Moreover, the dishwasher of this invention has the washing | cleaning tank which wash | cleans the tableware stored in the tableware storage basket of Claim 1, and the said tableware storage basket, and it wash | cleans by an inexpensive and simple structure.

The lower end of the side is supported, and at the tip of the protruding part that is long in the vertical direction of the second support member, The tableware can be set by supporting the upper wall on the outer peripheral side of the tableware, and when looking at the outer periphery of the tableware, the tableware with a large curvature and the tableware with a low curvature Since the position of the wall surface is almost the same, various shapes of tableware can be easily set. In addition, there is a gap between the first support member and the second support member, and since the tableware and the protrusion are in point contact, the protrusions found in a conventional rod-shaped wire rod basket are fanned out. As a result, the overlapping range of the tableware and the protrusion when viewed from the nozzle side is increased, and the cleaning water ejected from the nozzle on the lower surface of the basket is blocked by the protrusion, so that the problem of deteriorating the cleaning performance does not occur. Is. And even if it does not incline a protrusion part in the diagonal direction, there exists an effect equivalent to the protrusion part which spreads in the conventional fan shape. In addition, since it is not necessary to increase the thickness of the protruding portion in order to give strength, it is possible to configure the cage having the protruding portion with resin. Therefore, it is possible to provide a tableware storage basket in which tableware can be set without deteriorating cleaning performance and without cost.

Further, the lengths of the protrusions of the two rows of the second support members are different from each other, and the gap between the second support member having one short protrusion and the first support member is set to the other long protrusion. It is configured to be smaller than the gap between the second support member having the portion and the first support member, and has various curvatures such as large curvature, small, large diameter, small, thick, thin, etc. It becomes easy to deal with shaped tableware, and the setability of the tableware is further improved. For example, if the second support member having a short protrusion is provided on the inner peripheral side of the tableware and the second support member having a long protrusion is provided on the outer peripheral side of the tableware, the smaller tableware is shorter. Large tableware can be supported by the longer projection. In addition, when the second support member having a short protrusion is provided in front of the user as viewed from the user side, when the tableware is set, the tableware hits the protrusion, and the user sets the tableware. It will not be difficult.

It is a figure which shows the state which set the tableware in the storage basket. The same parts as those in the conventional example are denoted by the same reference numerals and the description thereof is omitted.

  1 to 3, reference numeral 15 denotes an upper basket that is a tableware storage basket in the present embodiment. The first support member 20 that has a concave groove 16 that supports the lower end of the tableware 10 is substantially parallel to the first support member 20. Two rows of rod-shaped second support members 21 having a plurality of projections 17 that are long in the vertical direction for supporting the other wall surface of the tableware 10 for setting the tableware 10 are provided in front and rear sides of the first row. The support member 20 is provided substantially in parallel. In addition, the height and pitch of the protrusions 17 of the second support members 21 in the front and rear two rows are provided to be different from each other. In the present embodiment, the shorter one of the front and rear projections 17 is provided on the inner peripheral side of the tableware 10, and the longer side is provided on the outer peripheral side of the tableware 10 from the shorter projection 17, and the user side As seen, the front side is a short protrusion 17. In the present embodiment, the upper basket 15 is made of resin.

  Next, operation | movement is demonstrated about the upper stage basket 15 for tableware storage comprised as mentioned above. In the set of the tableware 10, the concave groove 16 supports the lower end portion on the inner peripheral side of the tableware 10, and the upper end of the projection portion 17 which is long in the vertical direction is point-contacted to the upper side on the outer peripheral side of the tableware Supports the wall. Therefore, the tableware 10 can be set. Moreover, if the tableware 10 with a large curvature is also seen on the outer peripheral side of the tableware 10, the positions of the wall surfaces of the tableware 10 with a small curvature and the tableware 10 are almost the same. It is something that can be done.

  Moreover, since there is a gap between the first support member 20 having the groove 16 and the second support member 21 provided with the protrusion 17, and the tableware 10 and the protrusion 17 are in point contact, The protrusion 14 seen in the basket made of a rod-shaped wire expands in a fan shape, thereby increasing the range of overlapping positions when viewed from the nozzle side of the tableware 10 and the protrusion 14, and the cleaning jetted from the nozzle 3 on the lower surface of the basket The protrusion 14 blocks water, and the problem of deteriorating the cleaning performance does not occur.

  Moreover, according to the present embodiment, the protrusion 17 does not have to be inclined in an oblique direction, and can be shortened compared to the conventional protrusion 14, so that the thickness of the protrusion 17 is increased in order to provide strength. Therefore, the cage having the protrusions 17 can be made of resin as in the present embodiment. Therefore, it is possible to provide a tableware storage basket in which the tableware 10 can be easily set without deteriorating the cleaning performance and without cost.

  Moreover, by forming the protrusions 17 of the front and rear second support members 21 to have different heights and pitches, the tableware 10 has a large curvature, a small curvature, a large diameter, a small thickness, a thick thickness, a thin thickness, etc. It becomes easy to deal with tableware 10 of various shapes, and the setability of tableware 10 is further improved.

  This effect will be described with reference to FIG. In order to facilitate the explanation in the figure, if one of the projections 17 of the front and rear second support members 21 has a shorter one as a projection 18 and the other longer one as a projection 19, the shorter projection 18 Is provided on the inner peripheral side of the tableware 10 and the longer protrusion 19 is provided on the outer peripheral side of the tableware 10 than the shorter protrusion 18, it is possible to deal with both small and large tableware. This is because the small tableware 10 can be supported by the shorter projection 18, and the large tableware 10 is not supported by the shorter projection 18 alone, but is supported by the longer projection 19. Because it is done.

  In addition, when the front side is a short protrusion 18 when viewed from the user side, the tableware 10 hits the protrusion 18 when the tableware 10 is set, and it is difficult for the user to set the tableware 10. It will be lost. In addition, if the distance from the center of the dish to the shorter projection 18 and the distance from the tip of the longer projection 19 are the same so that the set of large tableware 10 is stabilized, the larger The stability of the set of tableware 10 is further increased.

  In the present embodiment, the first and second support members 20, 21 are used for the upper basket 15, but even when used for the lower basket 5, the same effects as the upper basket 15 can be obtained.

  As described above, the dish storage basket according to the present invention has an inexpensive and simple configuration and is excellent in the storage capacity of dishes having different sizes and shapes, and can be widely applied to household and commercial dishwashers. It is.
