Description

TECHNICAL FIELD The present invention relates to a dishwasher equipped with a dishwasher basket for supporting tableware therein.

A dishwasher includes a washing tank and a dish basket that supports tableware within the washing tank. Tableware that can be washed by a dishwasher includes items of different shapes, such as large plates, medium bowls, small plates, bowls, and cooking containers (frying pans and pots). These tableware are supported by the tableware basket by being inserted between multiple support rods or support pins provided on the tableware basket, and are then placed in the washing tank in this state to be washed. be exposed.

A tableware basket includes a large number of support rods and support pins having different height dimensions and bent shapes, and the area for supporting a given tableware is approximately determined by the size and spacing of the support rods and support pins.

By the way, depending on the size and type of tableware, it may not fit into any of the support areas and may be unavoidably set in the wrong position, or dishes of different shapes may be mixed irregularly and set in the tableware basket. There may be cases where you do so. However, in this case, there is a risk that the cleaning water may not properly hit each dish, resulting in a decrease in cleaning efficiency.

Therefore, a tableware basket has been proposed in which the interval between adjacent support rods (the support interval in the depth direction of the tableware) can be changed in a part of the tableware basket (see Patent Document 1 below). However, when changing the spacing between the support rods, it is only possible to accommodate the large and small depth dimensions of the dishes, etc., but in most cases it is not possible to accommodate the large and small outer diameters of the tableware, and it is difficult to adjust the distance between the tableware. There is an inconvenience that the tableware cannot be stably supported due to interference between the tableware and the inner wall surface of the washing tank.

In addition to this, a tableware basket has been proposed in which a container for small items is movably provided and the container covers a support member that supports some tableware and the like that are not placed frequently (see Patent Document 2). (see 2).

In this device, when supporting tableware and the like that are placed infrequently, the accessory case is moved to expose the support member that supports the tableware and the like that are placed infrequently. However, the accessory case is formed to be relatively small in order to support chopsticks, spoons, etc., and the area that can be covered and hidden on the tableware basket is relatively small. Therefore, even if the accessory case is moved on the tableware basket, it is difficult to support, for example, tableware with a large outer diameter at the relevant position.

In view of the above, an object of the present invention is to provide a dishwasher equipped with a dish basket that can stably support dishes of different sizes by efficiently using the support space for the dishes. do.

In order to achieve such an object, the present invention provides a dishwasher comprising a washing tank and a dish basket provided inside the washing tank to support tableware, the dish basket being attached to the washing tank. The tableware includes a base frame to be accommodated, and a tableware support member provided on the base frame and capable of supporting a plurality of tableware arranged in a horizontal position, the base frame being supported by the tableware support member. A supporting member moving means is provided which extends horizontally along the radial direction of the tableware and allows the tableware supporting member to be placed at any position in the horizontal direction, and the tableware supporting member is attached to the supporting member moving means. In a dishwasher in which a plurality of dishwashers are provided so as to be movable along the tableware supporting member, the tableware supporting member is provided with a latch claw that projects in the moving direction of the tableware support member, and the latch claw is arranged in a radial direction along the supporting member. A pair of base frames are provided in such a shape that the edge of another flattened tableware facing in a direction crossing the extension direction of the member moving means can be hung, and the base frame is configured to prevent movement of the tableware supporting member. a plurality of horizontal members extending along the direction, the horizontal members are located below the tableware support member, and the centers of the two latching claws and the centers of the two horizontal members are the same. The two latching claws are provided so that they are located on a vertical line and the spacing between the outer edges of the two latching claws is larger than the spacing between the centers of the two horizontal members. Features.

According to the present invention, when tableware having a relatively large outer diameter is supported by the tableware support member, each tableware support member is arranged at a position where the outer periphery of the tableware does not interfere with other tableware or the inner wall surface of the washing tank. The support space can be expanded to accommodate dishes with a relatively large outer diameter.

Therefore, the space for supporting tableware can be used efficiently, and even tableware having a relatively large outer diameter can be easily supported.

By providing a hook that protrudes in the moving direction of the tableware support member, other tableware (for example, cooking utensils with a large outer diameter such as a frying pan) can be supported in the space created by moving the tableware support member. I can do it.

The latching claw has a shape that allows the edge of the tableware to be latched in another horizontal position (that is, in a direction different from the orientation of the tableware arranged on the tableware support member), so that it can be supported by the latching claw. The tableware that is placed is oriented in a different direction from the tableware that is arranged in plural on the tableware support member. Thereby, relatively large tableware (for example, a frying pan, etc.) can be supported in a posture that does not hinder the washing of the plurality of tableware arranged on the tableware support member. Therefore, according to the present invention, the support space for tableware can be used more efficiently.

Moreover, in the present invention, it is preferable that the support member moving means is a rail that allows the tableware support member to be moved in the horizontal direction.

By employing a rail as the support member moving means, the tableware support member can be placed at a desired position simply by sliding the tableware supported by the tableware support member along the rail. Thereby, the position and support space of each tableware support member can be easily adjusted by sliding each tableware support member according to the outer diameter of the tableware supported by the tableware support member.

A cleaning/draining pump 9 communicating with the reservoir 8 is installed at the bottom of the cleaning tank 3 . The cleaning/draining pump 9 supplies cleaning water to the cleaning nozzle 4 by rotating in the normal direction, and drains water from the cleaning tank 3 by rotating in the reverse direction.

A tableware basket 10 for supporting tableware is detachably attached to the washing tank 3. The cleaning nozzle 4 includes a lower nozzle 11 located below the tableware basket 10 and elongated in the horizontal direction, and a center nozzle 12 erected at the center of the lower nozzle 11 in the longitudinal direction.

The lower nozzle 11 spouts washing water toward the tableware basket 10 while rotating around a vertical axis at its longitudinally central portion. The lower nozzle 11 is configured to rotate by the reaction force of the jet of cleaning water supplied from the cleaning/drainage pump 9.

The center nozzle 12 is composed of a lower half 12a that rotates together with the lower nozzle 11, and an upper half 12b that is inserted into the lower half 12a so as to be vertically movable. When cleaning water is supplied from the cleaning/drainage pump 9, the center nozzle 12 rotates together with the lower nozzle 11, and the upper half 12b extends upward due to water pressure. Washing water is then jetted toward the dish basket 10 from the lower half 12a and upper half 12b of the center nozzle 12.

Here, the tableware basket 10, which is the gist of the present invention, will be explained in detail. As shown in FIG. 2, the tableware basket 10 includes a base frame 13 made of resin-coated metal wire, and a box-shaped accessory stand 14 made of synthetic resin. Although not shown, spoons, forks, chopsticks, etc. can be placed on the accessory stand 14.

As shown in FIG. 3, the tableware basket 10 has areas set in which tableware of different shapes, such as a large plate Wa, a bowl Wb, a small plate Wc, and a medium bowl Wd, are collectively supported.

That is, the tableware basket 10 includes a large plate support section 15 that is an area for supporting a large plate Wa, a bowl support section 16 that is an area that supports a bowl Wb, and a small plate support section 17 that is an area that supports a small plate Wc. , and a medium bowl support portion 18 which is an area that supports the medium bowl Wd.

As shown in FIG. 2, in the center of the tableware basket 10, there is a nozzle opening through which the center nozzle 12 is inserted while avoiding interference between the center nozzle 12 and each tableware (large plate Wa, bowl Wb, small plate Wc, medium bowl Wd). A frame portion 19 is formed.

As shown in FIG. 2, the platter support section 15 is formed by a plurality of metal support rods 21 coated with resin. Each support rod 21 is connected via a rotary shaft 23 that is rotatably supported by a large tray support frame 22 made of synthetic resin attached to a base frame 13, and each support rod 21 can be tilted in directions facing each other. It looks like this. Each set of two support rods 21 is in contact with the back side of the large plate Wa, and by setting the large plate Wa to be inserted between each set of support rods 21, the large plate Wa is placed sideways (sideways posture). It is now supported by

The small plate support part 17 includes a small plate support frame 24 that is integrated with the nozzle open frame part 19, and a plurality of small plate support pins 25 that are integrally formed with the small plate support frame 24, and each small plate support pin 25 has two One set of books supports the small plate Wc in a horizontally erected state (horizontal posture).

The medium bowl support part 18 includes a medium bowl support frame 26 adjacent to the small plate support frame 24 of the small plate support part 17, and a plurality of medium bowl support pins 27 integrally formed with the medium bowl support frame 26. A set of two 27 are adapted to hook the opening edge of the medium bowl Wd and support it in a horizontally erected state (horizontal posture).

The bowl support section 16 includes a plurality of (three in this embodiment) bowl support frames 28 having the same shape. All of the bowl support frames 28 correspond to the tableware support member of the present invention. The bowl support section 16 is prevented from coming off the base frame 13 by a pair of rails 29a, 29b, and is provided movably along both rails 29a, 29b.

Both rails 29a and 29b are provided over substantially the entire length of one side edge of the base frame 13. One rail 29a is provided by a synthetic resin member fixed to one side edge of the base frame 13, and the other rail 29b is formed on one side wall of the nozzle open frame portion 19 and the small plate support frame 24. There is. The rails 29a and 29b are employed as support member moving means in the present invention.

The bowl support frame 28 can be moved within the area of the bowl support section 16 along the direction in which the rails 29a and 29b extend. That is, the positions of the bowl support frames 28 shown in FIG. 2 are equidistant from each other, but by moving the bowl support frames 28 to the positions shown in FIG. 4, the outer diameter can be slightly reduced as shown in FIG. A large bowl We can be stably supported without interference between the bowls We.

As shown in FIG. 6, the bowl support frame 28 includes a plurality of bowl support pins 30 integrally formed, and a pair of bowl support pins 30 support the opening edge of the bowl Wb (or bowl We). By being hooked, the bowl Wb (or bowl We) is supported in a horizontally erect state.

Further, the bowl support frame 28 is provided with a pair of sliding contact portions 31 on each side edge facing the rails 29a, 29b. The sliding contact portion 31 comes into sliding contact with the rails 29a and 29b, as shown in FIG. As shown in FIGS. 6 and 7, a small protrusion 32 is formed at the tip of the sliding contact portion 31 to contact the vertical inner wall surface of the rails 29a, 29b. A thin protruding piece 33 is formed on the upper surface of the sliding contact portion 31 and is in contact with the upper inner wall surface of the rails 29a and 29b.

Both the small protrusion 32 and the thin protruding piece 33 have a small contact area with the rails 29a, 29b, thereby reducing the frictional resistance when the sliding contact portion 31 moves along the rails 29a, 29b and supporting the bowl. The frame 28 can be moved smoothly.

As shown in FIG. 7, the lower part of the bowl support frame 28 is also in contact with a horizontal member 34 provided on the base frame 13 and extending along the rails 29a, 29b. A plurality of horizontal members 34 are provided parallel to the rails 29a and 29b to reinforce the base frame 13, but by sliding the bowl support frame 28 on the horizontal members 34, Distortion of the support frame 28 is also prevented.

Further, a recess 35 is formed in the bowl support frame 28 at a position where it contacts the horizontal member 34. This prevents the bowl support frame 28 from becoming oblique to the rails 29a, 29b while the bowl support frame 28 is moving. Therefore, the posture of the bowl support frame 28 during movement can be stabilized, and the bowl support frame 28 can be moved smoothly.

Further, as shown in FIG. 6, a pair of locking claws 36 are provided on both sides of the bowl support frame 28 in the moving direction, respectively, so as to project horizontally. Since the bowl support frames 28 are movable in any direction along the rails 29a and 29b, it is possible to partially widen the interval between the bowl support frames 28. When supporting relatively large tableware (cooking container) such as a frying pan Wf using such a wide space, the edge can be hooked to the hook 36 to support it.

At this time, as shown in FIG. 8, the latching claws 36 are provided so that the centers of the two latching claws 36 and the centers of the two horizontal members 34 are located on approximately the same vertical line It is preferable that the latching claws 36 are provided so that the spacing b between the outer edges of the two latching claws 36 is larger than the spacing a between the centers of the horizontal members 34.

According to this, the frying pan Wf, etc., which is in a sideways position with its radial direction oriented in a direction intersecting the extending direction of the rails 29a, 29b, can be properly retained by the retaining claws 36 without rolling in the circumferential direction. Moreover, since the horizontal member 34 receives the load of the frying pan Wf, etc., distortion of the bowl support frame 28 can be prevented and a reliable latching state can be obtained.

In this embodiment, the three bowl support frames 28 are movable as tableware supporting members, but if there is sufficient space for each of the plurality of tableware supporting members to move, the tableware of the present invention can be used. The number of supporting members is not limited to three.

Further, in this embodiment, the rails 29a and 29b are used as the support member moving means in the present invention, but the support member moving means in the present invention is not limited to the rails 29a and 29b. For example, although not shown, instead of the rails 29a and 29b, a holding member having a plurality of short comb-shaped pins erected at the top may be provided so that the tableware support member (bowl support frame 28) can be held at any position. good.

In addition, in the present embodiment, the bowl support frame 28 provided within the area of the bowl support part 16 is taken as an example of the tableware support member, but the tableware support member is supported by the area where the tableware support member is movably provided and The tableware is not limited to those of this embodiment.
