Description

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

  Conventionally, in a dishwashing and drying machine, a dishware is divided into a first basket and a second basket, and the second basket is connected to the tip of the first basket via a pivot. It is known to fold and stand a car (see Patent Document 1).

  In this case, the upper surface of the second car portion is superimposed on the upper surface of the first car portion by inverting the second car portion with respect to the first car portion, and further, the first car portion and the second car portion The first car portion is made to stand up while maintaining the overlapping state of According to this, even if the tableware basket is large, it can be folded and stood up relatively small.

Japanese Utility Model Publication No. 62-100163

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

  Therefore, it can be considered that the first car portion and the second car portion are bent in a mountain-like shape via the hinge portion to be in a folded state by opposing the lower surfaces with each other. According to this, since the first car portion and the second car portion are erected at the same time as being bent like a mountain fold through the hinge portion, the folding operation becomes easy.

  In addition, when supporting dishes, it is necessary to maintain the first and second car portions in a horizontal posture. Therefore, when the first car portion and the second car portion are configured to be bent in a mountain fold, the valleys of the hinge portion abut each other when the first car portion and the second car portion are in the horizontal posture. It is conceivable to provide a contact surface for restricting the bending in the folding direction at the end portion on the hinge portion side of each of the first car portion and the second car portion.

  However, since both contact surfaces are in contact when washing dishes, the dirt components removed from the dishes and contained in the washing water intrude between the contact faces and adhere to them for a long time use May be deposited. Then, when the drying step is performed thereafter, the viscosity of the infiltrating dirt component is increased or hardened, and the contact surfaces are in an adhered state, which may make it impossible to smoothly fold.

  In view of the above-mentioned point, the present invention aims at providing a tableware washing drier which can maintain smooth folding operation of the 1st car part and the 2nd car part over a long period of time.

  In order to achieve the above object, the present invention provides a dishwashing / drying machine comprising a washing tank, and a tableware basket for supporting dishes in the inside of the washing tank, wherein the tableware basket is movable in the first cage portion and And a second car portion connected to the first car portion via a hinge portion, and when the first car portion and the second car portion are in a horizontal posture, the first car portion and the The lower surface of the first cage portion and the lower surface of the second cage portion face each other by bending the hinge portion like a mountain fold when the tableware can be supported on the upper surfaces of the two cage portions and the tableware is not supported. And the first and second car parts are respectively placed on the hinge side end when the first and second car parts are in a horizontal position. A control surface that abuts to restrict bending of the hinge in the valley folding direction, One of the control surfaces is characterized by comprising a protrusion that forms a gap between the two control surfaces by coming into contact with the other control surface when the first car portion and the second car portion are in the horizontal posture. I assume.

  According to the present invention, when the first car portion and the second car portion are in the horizontal posture, an air gap is formed between the two control surfaces by the projection. As a result, since the dirt component which has entered between the two control surfaces is smoothly discharged by the gap between the two control surfaces, it is possible to prevent both the contact surfaces from being bonded due to the dirt component, and the first cage portion And the second car can be maintained smoothly for a long time.

  Further, in the present invention, it is preferable that the protrusion is formed to extend in a direction intersecting the pivot axis of the hinge portion. With such a shape of the projection, the bending in the valley-folding direction of the hinge portion can be restricted with high strength even if the contact area with respect to the contact control surface is relatively small. In addition, when the first car portion and the second car portion are in the horizontal posture, the longitudinal direction of the protrusion is in the vertical direction. This makes it easy for the dirt component that has entered between the two control surfaces to flow downward along the projection, and the adhesion and deposition of the dirt component on the two control surfaces can be reliably reduced.

  Embodiments of the present invention will be described based on the drawings. The dish washing / drying machine 1 of the present embodiment shown in FIG. 1 is a built-in type installed and installed in a system kitchen, and the case 2 of the dish washing / drying machine 1 is open at the front and the washing tank 3 is opened. It accommodates in and out freely.

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

  Furthermore, at the bottom of the washing tank 3, a washing water reservoir 8 communicating with the inside of the washing tank 3 through the filter filter 7 is provided. Below the bottom of the cleaning tank 3, a cleaning / drainage pump 9 communicating with the reservoir 8 is installed. The cleaning / draining pump 9 supplies cleaning water to the cleaning nozzle 4 when it is rotated forward, and drains the cleaning tank 3 when it is rotated reversely.

  An upper dish cage 10 and a lower dish cage 11 are attached to the inside of the washing tank 3. The lower tableware basket 11 supports relatively large dishes W such as platters, small dishes, middle bowls, bowls, etc. The upper tableware basket 10 supports relatively small diameter and deep deep dishes W such as cups and drinking water. The upper tableware cage 10 corresponds to the tableware cage in the present invention. The detailed configuration of the upper tableware cage 10 will be described later.

  The cleaning nozzle 4 is provided by a horizontally extending lower nozzle 12 disposed below the lower dish cage 11 of the cleaning tank 3 and a center nozzle 13 erected at the longitudinal center of the lower nozzle 12. It is configured.

  The lower nozzle 12 spouts washing water toward the lower dish cage 11 while turning about the vertical axis at the longitudinal center thereof. The lower nozzle 12 is turned by the reaction force of the flush water supplied from the flush / drain pump 9.

  The center nozzle 13 is composed of a lower half 13a that rotates integrally with the lower nozzle 12 and an upper half 13b inserted in the lower half 13a so as to be movable up and down. When the washing water is supplied from the washing / draining pump 9, the center nozzle 13 rotates with the lower nozzle 12 and the upper half 13b extends upward by water pressure. And it wash | cleans radially from both the jet nozzle currently formed in the upper end part (boundary position with the upper half part 13b) of the lower half part 13a of the center nozzle 13, and the jet nozzle formed in the upper half part 13b Water is spouted.

  The upper tableware cage 10 is, as shown in FIGS. 2 to 4, a base frame 14, and a first cage section 16 made of synthetic resin rotatably coupled to the base frame 14 via a first hinge section 15, The first car portion 16 is provided with a second car portion 18 rotatably connected via a second hinge portion 17.

  The base frame 14 includes a pair of synthetic resin support frame members 19 extending in parallel, facing each other, and a connecting member 20 made of a resin-coated metal wire that connects the two support frame members 19 to each other. Both support frame members 19 rotatably support the first car portion 16 via the first hinge portion 15 at the rear end side. The first hinge portion 15 rotates the first car portion 16 with respect to the base frame 14 in such a direction that the tip end thereof is at the upper position.

  The second hinge portion 17 is provided at the boundary between the first car portion 16 and the second car portion 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 rotates the second car portion 18 in such a direction that the tip end thereof is at the lower position with respect to the first car portion 16.

  Although the details will be described later, the upper dish cage 10 is folded by the first hinge portion 15 and the second hinge portion 17 as shown in FIGS. 5 and 6.

  Further, as shown in FIG. 4, the 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), and the second restricting surface 21 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 of the second cage 18 (the end on the second hinge 17 side), and the axis of the second hinge 17 is provided on the second restricting surface 23. An elongated second protrusion 24 is formed extending in a direction intersecting with the second direction.

  And, as shown in FIG. 2 and FIG. 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 restricting surface 21. Is in contact with the second restricting surface 23, and the second projection 24 of the second restricting surface 23 is in contact with the first restricting surface 21. Thereby, the space | interval S is formed between the 1st control surface 21 and the 2nd control surface 23, and it mutually opposes.

  Further, as shown in FIG. 2 and FIG. 3, on both sides of the tip end portion of the first car portion 16, a first convex portion 25 which protrudes in the lateral direction is provided. On both sides of the position between the tip of the second cage portion 18 and the second hinge portion 17, a laterally projecting second protrusion 26 is provided.

  On the upper surface of both support frame members 19 of the base frame 14, a flat surface 27 extending rearward from the tip, an inclined surface 28 which is continuous with 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 abuts on 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. As a result, the horizontal attitude of the first cage portion 16 and the second cage portion 18 of the upper dishwasher 10 is maintained.

  Furthermore, 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. Also, the horizontal attitude of the first cage portion 16 and the second cage portion 18 of the upper table cage 10 is maintained.

  At this time, a gap S is formed between the first restricting surface 21 and the second restricting surface 23 by the first protrusion 22 and the second protrusion 24. The dirt component that has entered between the first restricting surface 21 and the second restricting surface 23 is difficult to stay between the first restricting surface 21 and the second restricting surface 23 by the air gap S. Furthermore, since the first projection 22 and the second projection 24 have an elongated shape extending in the vertical direction, the dirt component invading between the first restricting surface 21 and the second restricting surface 23 tends to flow downward. It has become.

  Moreover, the contact area of the first protrusion 22 in contact with the second restricting surface 23 is small, and the contact area of the second protrusion 24 in contact with the first restricting surface 21 is also small. Therefore, even if a dirt component intrudes into these contact surfaces, the influence on the folding operation is small.

  Thus, by providing the first projection 22 and the second projection 24, the adhesion of the dirt component to the space between the first control surface 21 and the second control surface 23 is reduced. The smooth folding operation of the upper tableware cage 10 can be maintained over a long period of time without any mutual adhesion.

  The upper tableware cage 10 is attached to the rear half of the washing tank 3, as shown in FIG. At this time, both support frame members 19 are detachably supported inside the cleaning tank 3 by contacting the upper ends of the plurality of projecting portions 30 projecting inward from opposite side wall surfaces of the cleaning tank 3. Since the upper tableware cage 10 is provided detachably from the cleaning tank 3, it can be removed from the cleaning tank 3 when, for example, placement of the tableware W on the upper tableware cage 10 is unnecessary.

  Further, when the first car portion 16 and the second car portion 18 are in the horizontal posture, the upper table dish 10 is provided with two rows of tableware placing portions 31 a that are curved as shown in FIGS. 2 and 3. , 31b are formed. A plurality of dishes W (see FIG. 1) are arranged in two rows and placed on each of the tableware placement portions 31a and 31b. Although not shown, since the tableware placing portions 31a and 31b are curved, the dishes W arranged along the tableware are arranged in a fan shape in plan view.

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

  As described above, the upper tableware cage 10 is formed with two rows of tableware placing portions 31a and 31b that are curved when the first car portion 16 and the second car portion 18 are in the horizontal posture. The first cage portion 16 and the second cage portion 18 have a shape divided along the axis of the second hinge portion 17 as shown in FIG. 3, so they can be bent without any trouble and can be smoothly folded. It is possible to

  In the upper dish cage 10 in the folded state, the second convex portion 26 of the second cage 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 cage 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 a result, as shown in FIG. 6, the folded state occurs at a position near the inner surface of the rear side wall 3 a of the cleaning tank 3.

  As a result, the cleaning tank 3 is opened relatively widely, and for example, as shown in FIG. 1, the work of supporting the dishes W on the lower dish cage 11 can be easily performed. At this time, the second convex portion 26 of the second cage portion 18 is engaged with the concave portion 29 of the support frame member 19 and the folded state of the upper tableware cage 10 is maintained. The lower tableware basket 11 can be set.

  In the present embodiment, the first protrusion 22 is formed on the first restricting surface 21 of the first car portion 16, and the second protrusion 24 is formed on the second restricting surface 23 of the second car portion 18. However, the present invention is not limited thereto, and if the air gap S is reliably formed between the first restricting surface 21 and the second restricting surface 23, the first protrusion 22 and the second protrusion 24 may be used. One or the other may be provided. In addition, since the first projection 22 and the second projection 24 can act as a reinforcing rib, providing the first projection 22 and the second projection 24 on the first restricting surface 21 and the second restricting surface 23, respectively. As a result, sufficient strength can be given to both the first restricting surface 21 and the second restricting surface 23, and the horizontal attitude of the upper dish cage 10 can be firmly maintained.

  Moreover, although the 1st hinge part 15 which rotates the 1st cage | basket part 16 is fixed to the rear end part of the support frame member 19 of the upper tableware cage 10 of this embodiment, although it does not show other than this, The first hinge portion 15 may be provided movable in the longitudinal direction of the support frame member 19 (in the front-rear direction). According to this, when setting the tableware W in the lower tableware cage 11, it becomes possible to move the first car portion 16 and the second car portion 18 to a position out of the way in the folded state, and the usability improves Do.
