Description

  The present invention relates to a dishwasher for washing and drying dishes.

  Conventionally, in a dishwasher / dryer, a tableware basket is divided into a first basket portion and a second basket portion, and the second basket portion is connected to the tip of the first basket portion via a rotating shaft, thereby One that folds and raises a car is known (see Patent Document 1).

  By inverting the second car part with respect to the first car part, the upper surface of the second car part is superposed on the upper surface of the first car part, and the first car part and the second car part The first car portion is erected while maintaining the state where the two are superposed. According to this, even if the tableware basket is large, it can be folded and relatively raised.

Japanese Utility Model Publication No. 62-100003

  However, the tableware basket having the structure as disclosed in Patent Document 1 requires two stages of work, the work of inverting the first car part and the second car part and the work of raising them when folded. ,troublesome.

  In view of this, it is conceivable that the first car portion and the second car portion are bent in a mountain fold shape via a hinge portion so that the lower surfaces thereof are opposed to each other so as to be in a folded state. According to this, since the first car part and the second car part stand up at the same time as being bent into a mountain fold shape via the hinge part, the folding work is facilitated.

  Moreover, when supporting tableware, it is necessary to maintain a 1st cage | basket part and a 2nd cage | basket part in a horizontal attitude | position. Therefore, when the first car part and the second car part are bent in a mountain fold shape, the first car part and the second car part come into contact with each other when they are in the horizontal posture, and the valley of the hinge part. It is conceivable to provide an abutment surface that restricts bending in the folding direction at the end of each of the first car portion and the second car portion on the hinge portion side.

  However, since both abutment surfaces are in a contact state when the tableware is being washed, dirt components that are removed from the tableware and contained in the wash water penetrate between the abutment surfaces and adhere to each other for long-term use. May accumulate. Then, when the drying process is performed thereafter, the contact surfaces may be in an adhesive state due to increase in viscosity of the dirt component that has entered or hardening, which may prevent smooth folding.

  In view of the above points, an object of the present invention is to provide a dishwasher / dryer capable of maintaining a smooth folding operation between a first car part and a second car part over a long period of time.

  In order to achieve the above object, the present invention provides a dishwasher / dryer comprising a washing tub and a tableware basket supporting the tableware inside the washing tub, wherein the tableware basket includes a first car part that can be moved freely. And a second car part connected to the first car part via a hinge part, and the first car part and the second car part when the first car part and the second car part are in a horizontal posture. Tableware can be supported on the upper surface of the two basket portions, and the lower surfaces of the first and second basket portions are opposed to each other by bending the hinge portion in a mountain fold shape when the tableware is not supported. When the first car part and the second car part are in the horizontal position, the first car part and the second car part are respectively at the end on the hinge part side. It has a regulating surface that abuts and regulates the bending of the hinge part in the valley folding direction. One regulating surface includes a protrusion that forms a gap between the regulating surfaces by contacting the other regulating surface when the first car portion and the second car portion are in a horizontal posture. And

  According to the present invention, when the first car portion and the second car portion are in the horizontal posture, a gap is formed between the restricting surfaces by the protrusion. As a result, the dirt component that has entered between the two regulation surfaces is smoothly discharged by the gap between the two regulation surfaces, so that it is possible to prevent the two contact surfaces from being bonded to each other by the dirt component. And a smooth folding operation of the second car portion can be maintained for a long time.

  In the present invention, it is preferable that the protrusion has a shape extending in a direction intersecting the rotation axis of the hinge portion. By forming the protrusions in such a shape, the bending of the hinge portion in the valley fold direction can be regulated with high strength even if the contact area with respect to the contact regulating surface is relatively small. And when the 1st cage | basket part and the 2nd cage | basket part become a horizontal attitude | position, the said protrusion becomes the attitude | position in which the longitudinal direction followed the up-down direction. As a result, the dirt component that has entered between the regulation surfaces easily flows downward along the protrusions, and adhesion and accumulation of the dirt component between the regulation surfaces can be reliably reduced.

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 FIGS. 2 to 4, the upper tableware basket 10 includes a base frame 14, a first cage portion 16 made of synthetic resin that is slidably coupled to the base frame 14 via a first hinge portion 15, and A second car portion 18 that is slidably coupled to the first car portion 16 via a second hinge portion 17 is provided.

  The base frame 14 includes a pair of synthetic resin-made support frame members 19 extending in parallel to face each other, and a connecting member 20 made of a resin-coated metal wire material that connects the two support frame members 19 to each other. Both support frame members 19 support the first car portion 16 on the rear end side thereof via the first hinge portion 15 so as to be freely slidable. The first car portion 16 is rotated by the first hinge portion 15 in a direction in which the tip is in an upper position with respect to the base frame 14.

  The second hinge part 17 is provided at the boundary between the first car part 16 and the second car part 18. That is, the rear end of the second car portion 18 is connected to the front end of the first car portion 16 via the second hinge portion 17. The second hinge portion 17 causes the second car portion 18 to rotate with respect to the first car portion 16 in the direction in which the tip is in the lower position.

  Although described later in detail, the upper table basket 10 is folded by the first hinge portion 15 and the second hinge portion 17 as shown in FIGS.

  Further, as shown in FIG. 4, a first restricting surface 21 is provided at the tip of the first car portion 16 (the end portion on the second hinge portion 17 side). An elongated first protrusion 22 extending in a direction intersecting the axis of the hinge portion 17 is formed. Similarly, a second restricting surface 23 is provided at the rear end (the end portion on the second hinge portion 17 side) of the second car portion 18, and the axis of the second hinge portion 17 is provided on the second restricting surface 23. An elongated second protrusion 24 extending in a direction intersecting with is formed.

  As shown in FIGS. 2 and 3, when the first car portion 16 and the second car portion 18 are in the horizontal posture, as shown in FIG. 4, the first protrusion 22 of the first regulating surface 21 is used. Comes into contact with the second restriction surface 23, and the second protrusion 24 of the second restriction surface 23 comes into contact with the first restriction surface 21. Thereby, the 1st control surface 21 and the 2nd control surface 23 form the space | gap S between them, and oppose each other.

  As shown in FIGS. 2 and 3, first convex portions 25 projecting in the lateral direction are provided on both sides of the tip portion of the first car portion 16. On both sides of the position between the tip of the second car portion 18 and the second hinge portion 17, second convex portions 26 that project in the lateral direction are provided.

  On the upper surface of both support frame members 19 of the base frame 14, a flat surface 27 extending rearward from the front end, an inclined surface 28 that continues to the flat surface 27 and gradually rises rearward, and a rear end of the inclined surface 28. A continuous recess 29 is formed. The flat surface 27 of the support frame member 19 comes into contact with the first convex portion 25 of the first car portion 16 and the second convex portion 26 of the second car portion 18 from below. Thereby, the horizontal attitude | position of the 1st cage | basket part 16 and the 2nd cage | basket part 18 of the upper tableware basket 10 is maintained.

  Further, as shown in FIG. 4, the first protrusion 22 of the first restricting surface 21 abuts on the second restricting surface 23, and the second protrusion 24 of the second restricting surface 23 abuts on the first restricting surface 21. In addition, the horizontal posture of the first car portion 16 and the second car portion 18 of the upper tableware basket 10 is maintained.

  At this time, the first protrusion 22 and the second protrusion 24 form a gap S between the first restriction surface 21 and the second restriction surface 23. Due to the gap S, the dirt component that has entered between the first restriction surface 21 and the second restriction surface 23 is less likely to stay between the first restriction surface 21 and the second restriction surface 23. Furthermore, since the first protrusion 22 and the second protrusion 24 have an elongated shape extending in the vertical direction, dirt components that have entered between the first restricting surface 21 and the second restricting surface 23 can easily flow downward. It has become.

  In addition, the contact area of the first protrusion 22 that contacts the second restriction surface 23 is small, and the contact area of the second protrusion 24 that contacts the first restriction surface 21 is also small. Therefore, even if dirt components enter these contact surfaces, the influence on the folding operation is small.

  Thus, by providing the 1st protrusion 22 and the 2nd protrusion 24, adhesion of the dirt component between the 1st control surface 21 and the 2nd control surface 23 is reduced, and both the control surfaces 21 and 23 are provided. The smooth folding operation of the upper tableware basket 10 can be maintained over a long period of time without being bonded to each other.

  The upper tableware basket 10 is attached to the rear half of the washing tub 3 as shown in FIG. At this time, both support frame members 19 are detachably supported inside the cleaning tank 3 by abutting against the upper ends of a plurality of projecting portions 30 that protrude inward from the opposite side walls of the cleaning tank 3. Since the upper tableware basket 10 is detachably provided from the washing tub 3, it can be removed from the washing tub 3 when it is not necessary to place the tableware W in the upper tableware basket 10, for example.

  Moreover, when the 1st cage | basket part 16 and the 2nd cage | basket part 18 are made into the horizontal attitude | position, as shown in FIG.2 and FIG.3, as shown in FIG.2 and FIG.3, two rows of tableware mounting parts 31a which curve. , 31b are formed. A plurality of tablewares W (see FIG. 1) are placed in two rows on each of the tableware placement units 31a and 31b. In addition, although illustration was abbreviate | omitted, since the tableware mounting parts 31a and 31b are the shapes which curve, the tableware W arranged along this is arranged in fan shape in planar view.

  The upper tableware basket 10 configured as described above is bent in a mountain fold shape by the second hinge part 17 at a predetermined folding position, and the lower surfaces of the first car part 16 and the second car part 18 are opposed to each other. As a result, as shown in FIG.

  As described above, the upper tableware basket 10 is formed with two rows of tableware placement portions 31a and 31b that are curved when the first basket portion 16 and the second basket portion 18 are in the horizontal posture. As shown in FIG. 3, the first car portion 16 and the second car portion 18 are divided along the axis of the second hinge portion 17, so that they can be bent without hindrance and smoothly folded. Can be done.

  In the folded upper table basket 10, the second convex portion 26 of the second basket portion 18 is engaged with the concave portion 29 of the support frame member 19 and the folded state is maintained.

  And in this embodiment, as shown in FIG. 3, the upper tableware basket 10 is attached to the back half part of the washing tank 3, and the 1st hinge part 15 is provided in the rear-end side of the support frame member 19. As shown in FIG. Thereby, as shown in FIG. 6, it will be in the folding state in the position near the inner surface of the rear side wall 3a of the washing tank 3.

  Thereby, the washing tank 3 is opened relatively large, and for example, as shown in FIG. 1, the work of supporting the tableware W on the lower tableware basket 11 can be easily performed. At this time, the second convex portion 26 of the second basket portion 18 is locked to the concave portion 29 of the support frame member 19 so that the folded state of the upper tableware basket 10 is maintained. Can be set in the lower tableware basket 11.

  In the present embodiment, the first protrusion 22 is formed on the first restriction surface 21 of the first car portion 16, and the second protrusion 24 is formed on the second restriction surface 23 of the second car portion 18. However, the present invention is not limited to this, and the first protrusion 22 and the second protrusion 24 may be used as long as the gap S is reliably formed between the first restricting surface 21 and the second restricting surface 23. One of them may be provided. Since the first protrusion 22 and the second protrusion 24 can act as reinforcing ribs, the first protrusion 22 and the second protrusion 24 are provided on the first restricting surface 21 and the second restricting surface 23, respectively. Thus, sufficient strength can be imparted to both the first restriction surface 21 and the second restriction surface 23, and the horizontal posture of the upper tableware basket 10 can be firmly maintained.

  Moreover, although the 1st hinge part 15 which rotates the 1st cage | basket part 16 is being fixed to the rear-end part of the support frame member 19, the upper tableware basket 10 of this embodiment is not shown in figure other than this, The first hinge portion 15 may be provided movably along the longitudinal direction of the support frame member 19 (in the front-rear direction). According to this, when the tableware W is set in the lower tableware basket 11, the first basket portion 16 and the second basket portion 18 can be moved to an unobstructed position in a folded state, and the usability is improved.
