  2. Description of the Related Art There is known a dishwasher in which a washing nozzle that rotates in a washing tank is provided, and washing water spouted while the washing nozzle rotates is applied to the tableware supported on the tableware basket to wash the tableware.

  The tableware basket provided in this type of dishwasher tilts the tableware so that the wash water sprayed from the washing nozzle enters the tableware through the tableware opening in the case of relatively small diameter and deep bottom tableware such as cups and hot water only. It supports in the posture made to do (for example, refer to patent documents 1).

Japanese Patent Laying-Open No. 2009-160282 (FIG. 1)

  By the way, the washing water ejected from the washing nozzle changes so that the ejection direction forms an arc as the washing nozzle rotates. On the other hand, the conventional tableware basket found in Patent Document 1 and the like supports a plurality of tableware arranged in a straight line.

  For this reason, the manner in which the wash water is applied differs depending on the support position of the tableware, or in particular, since the wash water may hardly enter inside the tableware located on both ends in the arrangement direction, a plurality of dishes should be evenly distributed. There was an inconvenience that could not be washed.

  In view of the above points, an object of the present invention is to provide a dishwasher that can uniformly wash a plurality of tableware and obtain a high cleaning effect.

In order to achieve such an object, the present invention provides a washing nozzle, a washing nozzle for rotating the washing water for washing the tableware supported by the tableware basket and the tableware basket supporting the tableware in the washing tank. The tableware basket has a posture in which the opening side of each tableware faces the cleaning nozzle side, and is movable in the fan- shaped circumferential direction so as to have a fan shape in plan view. characterized in that it comprises dishes mounting portion is curved so as to support a plurality of dishes to be.

  In the tableware washing machine of the present invention, the tableware basket arranges a plurality of tableware in a fan shape in a plan view and supports the opening side of each tableware so as to face the cleaning nozzle side. As a result, the cleaning water ejected from the rotating cleaning nozzle can reliably hit the interior of any tableware arranged in a fan shape in plan view, and can evenly clean a plurality of dishes. An effect can be obtained. Furthermore, by arranging the tableware in a fan shape in a plan view, a relatively wide gap is formed between the adjacent tableware. Thereby, it is easy for the washing water to hit the outer peripheral surface of the tableware, and a high washing effect can be obtained.

The present invention also relates to a dishwasher comprising: a washing tub ; a washing tub that supports dishes in the washing tub; and a washing nozzle that spouts washing water for washing the dishes supported by the tableware basket. The tableware basket has a posture in which the opening side of each tableware is directed to the washing nozzle side and supports a plurality of tableware so as to have a fan shape in a plan view, and is formed of a synthetic resin to support the tableware. An opening abutting portion that sometimes abuts the opening edge of the tableware, and a peripheral wall abutting portion that abuts the outer peripheral surface of the tableware with the opening edge abutting against the opening abutting portion, the opening abutting portion And the peripheral wall abutting portion includes a hanging plate extending downward and having a plate surface facing the cleaning nozzle, and an arch-shaped notch is formed in a lower portion of the plate surface of the hanging plate. .

In recent years, a tableware basket is formed of a synthetic resin because it has advantages such as good moldability, easy weight reduction, and prevention of tableware damage. On the other hand, if the tableware basket is made of synthetic resin, the strength may be lower than that of a tableware basket made of a metal wire.

According to the present invention, the drooping plate can give sufficient strength to the opening contact portion and the peripheral wall contact portion made of synthetic resin. Furthermore, in the present invention, by providing an arch-shaped cutout in the lower part of the plate surface of the drooping plate, the washing water easily hits the tableware through the cutout, and a high washing effect is obtained. In addition, since the washing water hitting the surface of the drooping plate flows smoothly along the lower edge of the notch arch shape, high drainage performance is obtained.

In the present invention, it is preferable that the tableware basket support the tableware arranged in a fan shape in a plan view in a plurality of rows from the side of the cleaning nozzle toward the outside of the washing water ejection direction. According to this, many tableware can be washed satisfactorily.

Furthermore, when the inclination angle of the axis of the tableware supported by the tableware basket with respect to the horizontal line is taken as the posture angle of the tableware, the tableware basket is more than the posture angle of the tableware arranged at a position closer to the washing nozzle. It is preferable to support each tableware so that the posture angle of the tableware arranged at a position far from the washing nozzle is small.

According to this, it is possible not only to clean the dishes arranged at a position far from the washing nozzle, but also from the washing nozzles without being disturbed by the dishes arranged at a position near the washing nozzle. The washing water can be reliably applied also to the inside of the tableware arranged at a far distance.

  Embodiments of the present invention will be described with reference to the drawings. The dishwasher 1 according to this embodiment shown in FIG. 1 is a built-in type that is installed in a system kitchen, and the housing 2 of the dishwasher 1 is opened at the front so that the washing tub 3 can be taken in and out. Is housed in.

  A cleaning nozzle 4 for ejecting cleaning water is provided on the bottom side of the cleaning tank 3, and a drying duct for introducing drying air for drying dishes in the cleaning tank 3 on the back side of the cleaning tank 3. 5 and a drying fan 6 are provided.

  Furthermore, at the bottom of the cleaning tank 3, there is provided a cleaning water reservoir 8 that communicates with the inside of the cleaning tank 3 via a leftover filter 7. A cleaning / drainage pump 9 communicating with the reservoir 8 is installed below the bottom of the cleaning tank 3. The cleaning / drainage pump 9 supplies cleaning water to the cleaning nozzle 4 when rotated forward, and drains the cleaning tank 3 when rotated reversely.

  An upper table basket 10 and a lower table basket 11 are attached to the inside of the washing tub 3. The lower tableware basket 11 supports a relatively large tableware W such as a large plate, a small plate, a medium bowl, and a bowl, and the upper tableware basket 10 supports a tableware W having a relatively small diameter and a deep bottom such as a cup or a cup of water. In addition, the upper tableware basket 10 of this embodiment is equivalent to the tableware basket in this invention. The detailed configuration of the upper tableware basket 10 will be described later.

  The washing nozzle 4 includes a lower nozzle 12 that is horizontally disposed below the lower dish basket 11 of the washing tub 3 and a center nozzle 13 that is erected at the center in the longitudinal direction of the lower nozzle 12. It is configured.

  The lower nozzle 12 spouts washing water toward the lower table basket 11 while turning around the vertical axis at the center in the longitudinal direction. The lower nozzle 12 is turned by the reaction force of the washing water supplied from the washing / drainage pump 9.

  The center nozzle 13 includes a lower half 13a that rotates integrally with the lower nozzle 12, and an upper half 13b that is inserted in the lower half 13a so as to be movable up and down. When cleaning water is supplied from the cleaning / drainage pump 9, the center nozzle 13 rotates with the lower nozzle 12, and the upper half 13 b extends upward by water pressure. Then, cleaning is performed radially from both the jet outlet formed at the upper end of the lower half 13a of the center nozzle 13 (the boundary position with the upper half 13b) and the jet formed at the upper half 13b. Water spouts out.

  Next, the upper table basket 10 in this embodiment is demonstrated in detail. As shown in FIG. 2, the upper table basket 10 is composed of a base frame 14 formed of a resin-coated metal wire, and a synthetic resin tableware support member 15 fixed to the base frame 14. As shown in FIG. 3, it is attached to the rear half of the cleaning tank 3.

  2 and 3, the base frame 14 includes a rotating shaft portion 16 that extends in the left-right direction on the rear end side, and a pair of front extending portions 17 that extend in parallel toward the front. I have.

  As shown in FIG. 4, the rotation shaft portion 16 is supported by a bearing portion 18 that is integrally formed at a position near the rear wall surface of the inner surfaces of the left and right side walls of the cleaning tank 3. The bearing portion 18 includes a projecting portion 19 projecting from the inner surface of the side wall of the cleaning tank 3 and a recess 20 formed in the projecting portion 19, and the rotation shaft portion 16 is rotatably supported by the recess 20. . Thereby, the upper tableware basket 10 rotates so as to stand up toward the rear side of the washing tub 3.

  Further, since the upper portion of the concave portion 20 is opened, the rotation shaft portion 16 is detachably supported by the concave portion 20. Thereby, the upper tableware basket 10 can be easily removed upward from the washing tub 3. An inclined surface 21 is formed on the upper surface of the projecting portion 19 of the bearing portion 18 so as to incline toward the concave portion 20. Since the rotating shaft portion 16 is guided by the inclined surface 21 in the direction in which the rotating shaft portion 16 is attached to the concave portion 20, the removed upper tableware basket 10 can be smoothly attached to the cleaning tank 3.

  As shown in FIG. 5, the front extension portion 17 is abutted and supported by the upper ends of the abutting step portions 22 formed integrally with the inner surfaces of the left and right side walls of the cleaning tank 3. When the front extension part 17 contacts the upper end of the contact step part 22, the upper tableware basket 10 is in a horizontal posture.

  In addition, as shown in FIGS. 2 and 3, the tableware support member 15 includes two rows of tableware placement units (a first tableware placement unit 23 and a second tableware placement unit 24) that are curved. By placing a plurality of tableware W side by side on each of the first tableware placement unit 23 and the second tableware placement unit 24, the tableware W is supported in a two-row plan view fan shape as shown in FIG. Is done.

  Here, for example, unlike the present embodiment, when the dishes W are arranged in a straight line, the distance between the center nozzle 13 and each tableware W is larger than the dishes W located in the center in the arrangement direction. The tableware W located on both end sides in the arrangement direction becomes longer. In addition, the cleaning water ejected radially from the center nozzle 13 scatters in a circle as the center nozzle 13 rotates. Therefore, since there is little washing water hitting the tableware W located on both ends in the arrangement direction and the hydraulic power is also reduced, the cleaning effect on the tableware W located on both ends in the arrangement direction is low.

  On the other hand, in this embodiment, the tableware support member 15 supports the tableware W in a fan shape in a plan view. Thereby, compared with the case where the tableware W is arranged in the shape of a straight line, the distance from the center nozzle 13 is not so long for the tableware W located on both ends in the arrangement direction. Therefore, since the washing water which hits the tableware W located in the both ends of the arrangement direction which is a fan shape in plan view can maintain a sufficient amount and hydraulic power, each tableware W can be washed uniformly, and a high cleaning effect can be obtained. Can be obtained.

  Moreover, the comparatively wide clearance gap is formed between the tableware W which adjoins mutually by arranging the tableware W in planar view fan shape. Thereby, it is easy for the washing water to hit the outer peripheral surface of the tableware W, and a high washing effect can be obtained.

  Furthermore, as described above, the tableware W is supported in a fan shape in a plan view so that a high cleaning effect can be obtained, so that the amount of cleaning water used can be reduced and sufficient cleaning can be performed, thereby reducing the number of outlets of the center nozzle 13. It can also be reduced.

  As shown in FIG. 7, the first tableware placement unit 23 and the second tableware placement unit 24 include an opening contact portion 25 that contacts the opening edge of the tableware W when the tableware W is supported, A peripheral wall abutting portion 26 for abutting the outer peripheral surface of the tableware W with the opening edge abutting on the contact portion 25 is provided. The tableware W is in contact with the opening abutting portion 25 and the peripheral wall abutting portion 26 so that the opening is inclined toward the center nozzle 13 and the first tableware placing portion 23 and the second tableware placing portion 24 Placed on.

  Further, from the center nozzle 13, washing water is ejected from different outlets toward the tableware W of the first tableware placement unit 23 and the tableware W of the second tableware placement unit 24. At this time, since the tableware W of the second tableware placement unit 24 is supported at a position farther from the tableware W of the first tableware placement unit 23 than the tableware W of the first tableware placement unit 23, the washing water in the center nozzle 13 The jet angle with respect to the horizontal line is set so that the angle of the second tableware placement unit 24 to the tableware W is smaller than the angle of the first tableware placement unit 23 to the tableware W.

  In consideration of this, the upper tableware basket 10 supports the tableware W in different inclination postures in the first tableware placement unit 23 and the second tableware placement unit 24. That is, when the inclination angle of the axis p of the tableware W with respect to the horizontal line x is the posture angle of the tableware W, the upper tableware basket 10 has the posture angle f of the tableware W of the first tableware placement unit 23 as shown in FIG. The tableware W is supported so that the posture angle r of the tableware W in the second tableware placement unit 24 becomes smaller. According to this, the tableware W can be supported in a posture corresponding to the washing water ejected from the center nozzle 13, and the washing water is also reliably disposed inside the tableware W arranged at a position far from the center nozzle 13. Can be applied. Note that the posture angles f and r of the tableware W supported by the first tableware placement unit 23 and the second tableware placement unit 24 are appropriately set according to the distance between the opening contact portion 25 and the peripheral wall contact portion 26. Is possible.

  Moreover, as shown in FIG. 2, the opening contact part 25 and the peripheral wall contact part 26 of the tableware support member 15 are each provided with the drooping board 27 extended below. Since the tableware support member 15 is made of a synthetic resin, there are advantages that the moldability is good, the weight can be easily reduced, and the tableware W can be prevented from being damaged. Further, the hanging plate 27 ensures high strength. Can do.

  On the other hand, since the plate surface of the drooping plate 27 faces the center nozzle 13 side, if the washing water ejected from the center nozzle 13 hits the drooping plate 27, the washing water does not reach the tableware W and may be wasted.

  Therefore, as shown in FIG. 2, a plurality of arch-shaped notches 28 are formed in the lower part of the plate surface of the hanging plate 27. According to this, since the washing water ejected from the center nozzle 13 easily hits the tableware W through the notch 28 and the amount of the washing water hitting the hanging plate 27 is reduced, the washing water is prevented from being wasted. be able to.

  Furthermore, each notch 28 of the drooping plate 27 has an arch shape, so that a protrusion 29 protruding downward is formed at the boundary of each notch 28. As a result, the washing water flowing down from each tableware W supported by the tableware support member 15 and the washing water hitting the drooping plate 27 travels along the lower edge of the arch-shaped cutout 28, and further gathers at each projection 29 at the lower end to smoothly Therefore, high drainage can be obtained.
