  However, the conventional tableware basket is configured in such a manner that the upper tableware basket and the lower tableware basket are connected to each other, and the lower tableware basket is configured to rotatably support the upper tableware basket. Configuration is required. Furthermore, it is necessary for the lower tableware basket to have the strength to support the load of the tableware placed on the upper tableware basket. For this reason, there is an inconvenience that the configuration of the tableware basket becomes extremely complicated.

  In view of the above points, an object of the present invention is to provide a dishwasher that can greatly simplify the structure of a tableware basket and reduce the load on the tableware basket.

  In order to achieve such an object, the present invention provides a dishwasher comprising a washing tub having an open top and a tableware basket supporting the tableware inside the washing tub, wherein the washing tub is disposed on the inner surface of the peripheral wall. A bearing portion for pivotally supporting the tableware basket so as to be rotatable and detachable is integrally provided.

  According to the present invention, since the bearing portion for pivotally supporting the tableware basket is integrally provided on the inner surface of the peripheral wall of the cleaning tank, the tableware basket has only a portion for pivotally supporting the bearing portion. The structure of the tableware basket that can be freely rotated can be made extremely simple, and the load on the tableware basket can be reduced.

  Further, in the present invention, the bearing portion has an upper end so as to be freely mountable with a protruding portion that protrudes from the inner surfaces of the circumferential walls facing each other of the cleaning tank and a rotation shaft that is formed on the protruding portion and is provided in the tableware basket. A groove-shaped recess that is open and closed at the lower end, and the rotation shaft of the tableware basket is seated on the lower end of the recess and is rotatable.

  According to this invention, the bearing part of a washing tank is provided with a recessed part, and a tableware basket is attached in a washing tank by attaching the rotating shaft to the recessed part of a bearing part. As a result, the structure of the bearing portion can be made extremely simple and the tableware basket can be rotated freely, and the support of the rotation axis of the tableware basket by the recess can be released and the tableware basket can be easily removed from the washing tub. it can.

  At this time, it is preferable that the protruding portion of the bearing portion includes an inclined surface that gradually descends toward the concave portion on the upper end surface. According to this, since the rotation axis of the tableware basket is reliably guided toward the concave portion of the bearing portion by the inclined surface, the operation of mounting the rotation axis of the tableware basket on the concave portion of the bearing portion is facilitated and reliable. Can be attached to.

  Further, the present invention provides a dishwasher comprising a washing tub having an open top and a tableware basket supporting the tableware inside the washing tub, wherein the washing tub rotates the tableware basket on an inner surface of a peripheral wall thereof. When the tableware basket is rotated from a horizontal posture to a standing posture with the shaft support position by the bearing portion as a fulcrum, the center of gravity of the tableware basket is the fulcrum. A table that regulates rotation of the tableware basket at a position not exceeding a vertical line passing through the table, and the tableware basket regulated by the regulation unit is rotated by its own weight from a standing posture to a horizontal posture. It is characterized by.

  According to this, even if the tableware basket is rotated around the pivotal support position to be in the standing posture, the tableware basket can be prevented from being maintained in the standing posture because the tableware is in a horizontal posture by its own weight. Therefore, after rotating the tableware basket in the standing posture as necessary, the tableware basket can be smoothly returned to the horizontal posture so that the tableware can be placed on the tableware basket.

  Embodiments of the present invention will be described with reference to the drawings. The dishwasher 1 of this embodiment shown in FIG. 1 is a built-in type installed in a system kitchen, and a housing 2 of the dishwasher 1 has a washing tank 3 that can be pulled out forward. Contained.

  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. The upper tableware basket 10 corresponds to the tableware basket in the present 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.

  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.

  As shown in FIG. 2, the tableware support member 15 includes two rows of tableware placement portions 15 a and 15 b that are curved. A plurality of tablewares W are arranged in two rows on each of the tableware placement units 15a and 15b. In addition, although illustration was abbreviate | omitted, since the tableware mounting parts 15a and 15b are the shapes which curve, the tableware W arranged along this is arranged in fan shape in planar view.

  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 rotating shaft portion 16 is supported by a bearing portion 18 that is integrally formed at a position near the rear wall surface of the right and left side walls of the cleaning tank 3 that face each other. The bearing 18 includes a protrusion 19 that protrudes from the inner surface of the side wall of the cleaning tank 3 and a recess 20 that is formed in the protrusion 19. The recess 20 is formed in a groove shape having an upper end opened and a lower end closed. In addition, an inclined surface 21 is formed on the upper surface of the protruding portion 19 of the bearing portion 18 so as to be inclined toward the concave portion 20.

  The upper table basket 10 is pivotally supported in a state in which the rotation shaft portion 16 is seated on the lower end of the recess 20 of the bearing portion 18, thereby being rotatable in the standing direction. Moreover, since the upper end of the recessed part 20 is open | released, the rotating shaft part 16 can be easily escaped from the recessed part 20, and the attachment or detachment to the washing tank 3 of the upper tableware basket 10 can be performed easily. .

  Further, the rotating shaft portion 16 is guided in the direction of entering the concave portion 20 by the inclined surface 21 formed on the protruding portion 19 of the bearing portion 18, so that the upper table basket 10 can be easily attached to the washing tub 3. It can be carried out.

  Further, as shown in FIG. 5, the front extending portion 17 is abutted and supported by the upper ends of the abutting step portions 22 formed integrally with the left and right side wall inner surfaces 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.

  Thus, by providing the bearing portion 18 that pivotally supports the rotation shaft portion 16 of the upper table basket 10 on the inner surface of the side wall of the washing tub 3, the upper table basket 10 can be freely rotated to the lower table basket 11, for example. It is possible to make the structure easy to rotate without supporting it.

  By rotating the upper tableware basket 10 to the upright posture, as shown in FIG. 6, the upper side of the lower tableware basket 11 located below the upper tableware basket 10 is opened. Placement work of the tableware W becomes easy. Moreover, since the upper table basket 10 can be detached from the washing tub 3 independently of the lower table basket 11, the upper table basket 10 can be removed to widen the upper space of the lower table basket 11. Therefore, for example, when a relatively large object to be cleaned such as a pan is placed on the lower tableware basket 11, the upper tableware basket 10 does not get in the way, and the degree of freedom of the object to be cleaned increases.

  By the way, when the upper tableware basket 10 is raised by its rotation, the tip side of the upper tableware basket 10 protrudes to a position higher than the upper edge of the washing tub 3 as shown in FIG. If the standing state of the upper tableware basket 10 is maintained, the upper tableware basket 10 that protrudes from the upper part of the washing tub 3 interferes with the case 2 when the washing tub 3 drawn forward is returned to the case 2. There is a fear.

  Therefore, in the present embodiment, when the upper tableware basket 10 is erected in the standing direction, the rear end of the upper tableware basket 10 abuts against the rear wall inner surface 3a of the washing tub 3 so that it cannot be raised any further. It has become. The rear wall inner surface 3a of the cleaning tank 3 corresponds to a restricting portion of the present invention. That is, as shown in FIG. 6, the rear wall inner surface 3 a of the cleaning tank 3 that functions as a restricting portion is configured such that the center of gravity g of the upper tableware basket 10 is a rotation fulcrum (in the present embodiment, the rotation shaft portion 16 The rotation of the upper tableware basket 10 is restricted at a position not exceeding the vertical line x passing through the center).

  As a result, when the user rotates the upper table basket 10 in the upright direction by lifting the tip far from the rotation shaft 16 of the upper table basket 10, the rear end portion of the upper table basket 10 is the rear wall inner surface 3 a of the washing tub 3. And the rotation of the upper tableware basket 10 is restricted. At this time, the center of gravity g of the upper tableware basket 10 is located in front of the vertical line x passing through the rotation fulcrum by the bearing portion 18. When the user releases his hand from the upper tableware basket 10, the upper tableware basket 10 returns to the horizontal posture with its own weight without being able to maintain the standing state. Thereafter, the tableware W can be placed on the upper tableware basket 10 in a horizontal posture as shown in FIG.

  Thus, when the rear wall inner surface 3a of the washing tub 3 regulates the upper tableware basket 10 in the above-described state, when the washing tub 3 drawn forward is returned to the housing 2, the upper tableware basket prior to that is returned. 10 returns to a horizontal posture by its own weight, and interference between the upper tableware basket 10 and the housing 2 can be prevented. Further, since the upper tableware basket 10 changes from the standing posture to the horizontal posture by its own weight, the tableware W can always be placed, and the troublesome operation of rotating the upper tableware basket 10 in the standing posture to the horizontal posture is unnecessary. it can.

  In the present embodiment, the inner surface 3a of the rear wall of the cleaning tank 3 is used as a regulating portion in a flat state, so that the structure is extremely simple. This is made possible by the distance from the rear wall inner surface 3 a of the cleaning tank 3 to the bearing portion 18 and the shape of the rear end portion of the upper tableware basket 10. On the other hand, other than this, although not shown, a predetermined part of the upper tableware basket 10 is formed by forming a protrusion protruding from the rear wall inner surface 3a of the washing tub 3 toward the rear end of the upper tableware basket 10 as a restricting portion. Rotation of the upper tableware basket 10 may be regulated by bringing the upper table into contact with the projection.
