[0008] (Knowledge and other information that formed the basis of this disclosure) At the time the inventors conceived this disclosure, conventional dish racks were designed to efficiently set dishes in a tank of a predetermined capacity, and to improve the functionality of the upper basket so that dishes could be easily put in and taken out. It was designed to expand the area where it could be set up.

[0009] Therefore, the inventors introduced a configuration that improves the tableware setting performance by making the upper basket slidable and foldable, and by providing multiple auxiliary baskets. However, the inventors discovered that accessing the lower basket required multiple operations, such as folding and sliding the upper basket, which was cumbersome. To solve this problem, they arrived at the subject matter of this disclosure.

[0010] Therefore, this disclosure provides a dish rack that allows for easy access to the bottom of the dish rack by enabling the storage of the dish rack with minimal movement.

[0011] The embodiments will be described in detail below with reference to the drawings. However, unnecessary details may be omitted. For example, detailed explanations of already well-known matters or redundant explanations of substantially identical configurations may be omitted. This is to avoid the following explanation becoming unnecessarily verbose and to facilitate understanding for those skilled in the art.

[0012] The attached drawings and the following description are provided to enable those skilled in the art to fully understand this disclosure and are not intended to limit the subject matter described in the claims.

[0013] (Embodiment 1) Embodiment 1 will be described below with reference to Figures 1 to 8.

[0014] [1-1. Structure] [1-1-1. Overall Structure] Figure 1 is a schematic side view of the dishwasher in Embodiment 1 with the washing tank housed in the casing. Figure 2 is a schematic side view of the dishwasher in Embodiment 1 with the washing tank pulled out from the casing. More specifically, Figure 1 shows a schematic side view of the dishwasher with the washing tank 50 housed in the dishwasher casing 10. Figure 2 shows a schematic side view of the dishwasher with the washing tank 50 pulled out from the dishwasher casing 10.

[0015] The dishwasher of Embodiment 1 is, for example, an built-in dishwasher installed in a system kitchen or the like, and includes a washing tub 50 provided so as to be pullable. Hereinafter, the direction in which the washing tub 50 is pulled out is defined as the front direction, and the direction on the left side of a person viewing the dishwasher 1 from the front is defined as the left direction. Also, in the drawings, X represents the left direction, Y represents the front direction, and Z represents the upward direction.

[0016] The dishwasher 1 has a housing 10 installed inside a system kitchen or the like. The housing 10 is a box-shaped member that opens forward. The opening of the housing 10 is closed from the front by a door body 11.

[0017] Inside the housing 10, the washing tub 50 is accommodated. The washing tub 50 is a box-shaped structure having an upward opening 51 formed therein. Inside the washing tub 50, a dish basket 30 for placing dishes (objects to be washed) such as plates and cups is provided. The dish basket 30 is provided with an upper shelf basket 31 and a lower basket 32 arranged vertically in the washing tub 50, and each basket can be selectively used according to the application. The washing tub 50 is connected to the door body 11.

[0018] On the outer surface of the washing tub 50 in the left-right direction, a first rail 41 extending in the front-rear direction is provided. The washing tub 50 is supported so as to be movable in the front-rear direction with respect to the housing 10 by the first rail 41 being supported by a second rail 13 provided on the inner surface of the housing 10.

[0019] As shown in FIG. 1, when the washing tub 50 moves backward and is pushed into the housing 10, the door body 11 closes the opening of the housing 10. The washing tub 50 is pulled forward through the opening of the housing 10 to the outside such as a sink. As shown in FIG. 2, when the washing tub 50 is pulled forward, objects to be washed can be put into and taken out of the washing tub 50 through the opening 51.

[0020] When the cleaning tank 50 is housed in the housing 10, the opening 51 of the cleaning tank 50 is closed by a lid 15 provided on the housing 10. An annular rubber lid-side contact portion 16 is attached to the lower surface of the lid 15. The lid-side contact portion 16 seals the cleaning tank 50 by contacting the area around the opening 51. The lid 15 is mounted on the housing 10 so as to be able to move up and down via a parallel link mechanism 17 or the like. The lid 15 is configured to move downward to close the opening 51 when the cleaning tank 50 is housed in the housing 10, and to move upward to avoid interfering with the cleaning tank 50 when the cleaning tank 50 is pulled out.

[0021] Inside the cleaning tank 50, the required amount of cleaning water, such as tap water, is supplied from a branch faucet on the system kitchen or the like, via a water supply route (not shown) that includes a water supply hose, water supply pump, and water supply valve. The cleaning water supplied to the cleaning tank 50 circulates within the cleaning tank 50 via the cleaning pump 43 and cleaning nozzle 45.

[0022] The washing pump 43 is a pump that sends the washing water accumulated at the bottom of the washing tank 50 to the washing nozzle 45. The washing pump 43 is located on the outside lower part of the washing tank 50. The washing nozzle 45 is located inside the washing tank 50, below the dish basket 30, and is positioned near the center of the washing tank 50 in a plan view. The washing nozzle 45 has multiple nozzles 46 that spray washing water. The nozzles 46 open upwards. The washing nozzle 45 is configured to rotate about an axis in the vertical direction by the power of the motor or the recoil when the washing water is sprayed. The washing nozzle 45 washes the items to be washed placed in the dish basket 30 by rotating while spraying washing water upwards from the nozzles 46. In addition, a heater 47 is provided inside the washing tank 50. The heater 47 promotes the washing of the items to be washed by heating the washing water accumulated at the bottom of the washing tank 50.

[0023] The dishwasher 1 is equipped with a drainage route (not shown) for draining washing water from the washing tank 50. The drainage route consists of a drain pump and a drain hose connected to a kitchen drainpipe or the like. When washing and rinsing of the dishes to be washed is completed in the dishwasher 1, the drain pump is driven and the washing water is drained to the outside via the drain hose. In addition, at the start of operation, the dishwasher 1 also drives the drain pump before supplying washing water from the water supply route to drain any remaining water from the washing tank 50 from the previous operation. In this embodiment, a detergent inlet 60 is provided inside the washing tank 50, which supplies detergent to the washing tank 50 by spraying washing water from a washing nozzle 45.

[0024] Furthermore, the washing tub 50 is provided with a flat surface 52 positioned in front of the opening 51, which is the upper front outer surface of the washing tub 50. An operation unit 53 and a display unit (not shown) are arranged on the flat surface 52. The operation unit 53 allows the user to set the washing course of the dishwasher, turn the power on or off, etc. The display unit displays the washing status, operating status, time, etc. An operation display board (not shown) that controls the operation of the operation unit 53 and the display unit is located on the back side of the flat surface 52.

[0025] The side walls 54 are positioned on both sides between the washing tank 50 and the door body 11. The side walls 54 connect the washing tank 50 and the door body 11 so that they can move integrally. At this time, the dishwasher has a front space 55 that is formed by partitioning the front side of the washing tank 50, the rear side of the door body 11, the side walls 54 and the plane 52.

[0026] The door body 11 is equipped with a handle 56 that is positioned at the top and protrudes forward. The handle 56 is used by the user to grasp and move the washing tank 50 in and out of the housing 10.

[0027] In the front space 55, which is located outside the washing tank 50, a detergent tank or a drying accelerator tank may be housed instead of the detergent inlet 60 described above.

[0028] As described above, the dishwasher of Embodiment 1 is configured as described.

[0029] [1-1-2. Configuration of the washing basket] Next, we will explain the configuration around the dish rack 30 of the dishwasher, referring to Figures 2 to 5.

[0030] Figure 2 is a schematic perspective view of a dishwasher showing the upper basket 31 and the lower basket 32. Figure 3 is a schematic perspective view of the upper basket 31 with a small item container 33 and the auxiliary basket 314 in a horizontal position. Figure 4 is a schematic perspective view of the upper basket 31 with the auxiliary basket 314 upright and a portion of the upper basket 31 slid to the left. Figure 5 is a schematic perspective view of the upper basket 31 with the auxiliary basket 314 upright and a portion of the upper basket 31 slid to the right.

[0031] As shown in Figure 2, the dish rack 30 is provided with an upper shelf basket 31 and a lower basket 32, which are arranged vertically within the washing tank 50, for arranging dishes (items to be washed) such as plates and cups.

[0032] As shown in Figure 2, when the small storage containers 33 are installed at the left and right side ends at the same height as the upper shelf basket 31, the upper shelf basket 31 and the small storage containers 33 are configured to cover the upper space of the lower basket 32, and the upper shelf basket 31 and the small storage containers 33 can also accommodate the maximum capacity of tableware 6 without wasting any space.

[0033] [1-1-3. Configuration of the upper shelf basket] The upper shelf basket 31 comprises an upper shelf basket rail 316, a rotatable auxiliary basket 314, an upper shelf basket section 319, and a fixing wire 318 capable of supporting the auxiliary basket 314 and the upper shelf basket section 319 in an upright position. Figure 3 shows the auxiliary basket 314 and the upper shelf basket section 319 in a horizontal position, with the baskets laid flat. Figure 4 shows the upper shelf basket 31 with the auxiliary basket 314 in an upright position and the upper shelf basket section 319 in a horizontal position. Furthermore, a portion of the upper shelf basket 31 is configured to be movable laterally. Specifically, the basket section, which consists of the auxiliary basket 314 and the upper shelf basket section 319 and is the part on which dishes can be placed, and the fixing wire 318 are configured to be movable laterally.

[0034] <Regarding the upper shelf rail 316> An upper shelf rail 316 is placed along a protrusion (not shown) provided on the inner wall of the washing tank 50, and along the front and rear inner surfaces of the washing tank 50, extending horizontally from left to right.

[0035] As a result, the upper shelf basket 31 is detachably attached to the washing tank 50. The basket rails provided at the front and rear may also be connected so as to follow the left and right inner surfaces of the washing tank. In this embodiment, the upper shelf basket rail 316 extends along the left inner surface of the washing tank 50 and is connected to each other, so that the rail extends in a U-shape with the right side open when viewed from the front.

[0036] The upper shelf basket rails 316 are provided in two positions, vertically, along the inner walls of the front and rear of the washing tank 50. The upper of the two rails is designated as the first upper shelf basket rail 316a, and the lower rail is designated as the second upper shelf basket rail 316b.

[0037] First sliding parts 317 are provided at both ends of the upper shelf basket 31 in the front-rear direction. Furthermore, the upper shelf basket 311 is detachably mounted to the washing tank 50 by placing an upper shelf basket rail 316, which extends horizontally from left to right, along a protrusion (not shown) provided on the inner wall of the washing tank 50. The first sliding parts 317 are slidably fitted into a groove 316c formed between the first upper shelf basket rail 316a and the second upper shelf basket rail 316b. This allows the basket portion, which is part of the upper shelf basket 31, and the fixing wire 318 to move laterally in the left-right direction of the dishwasher above the lower basket 32.

[0038] Here, the upper shelf rail 316 restricts the range of movement of the upper shelf basket 31 by adjusting the length of the groove 316c. Specifically, the first sliding parts 317, provided at both ends of the upper shelf basket 31 in the front-rear direction, slide in the left-right direction along the groove 316c formed by the upper shelf rail 316. At this time, the groove 316c is configured to be divided near the left-right ends so that a part of the upper shelf basket 311 does not protrude from the upper shelf rail 316 or interfere with the inner surface of the washing tank 50. Specifically, the second upper shelf rail 316b is configured to be convex upward at its left-right ends compared to the first upper shelf rail 316a, thereby dividing the groove 316c. As a result, the first upper shelf rail 316a and the second upper shelf rail 316b intersect in some places, which increases the strength of the upper shelf rail 316. The method for dividing the groove 316c is not limited to the above. Any configuration that can restrict the movement of the first sliding part 317 is acceptable. For example, a part of the first upper shelf rail 316a may be configured to protrude upward to divide the groove 316c, or the configuration for dividing the groove 316c may be provided by a separate part.

[0039] Furthermore, when the upper shelf basket section 319 is in the rightmost position, which is the most positive X direction, the upper shelf second basket section 319B, which is the rightmost part, is configured to move freely on the upper shelf basket rail 316 and not frequently collide with the inner wall of the washing tank. The same applies when the opposite auxiliary basket 314 is in the leftmost position, which is the most negative X direction. In other words, the range of movement of the upper shelf basket 31 is restricted so that it does not move more freely on the upper shelf basket rail 316 than necessary. This configuration prevents the upper shelf basket 31 from moving unintentionally and hitting the inner wall of the washing tank, making noise, or from colliding with and damaging the dishes 6, while the dishes 6 are stored in the upper shelf basket 31.

[0040] Furthermore, in this embodiment, a first guide 311 is provided so as to be in contact with the upper shelf rail 316 that extends in the front-rear direction along the left inner surface of the washing tank 50. The first guide 311 is provided on the left side portion of the upper shelf rail 316 and is a wire that protrudes upward from the first upper shelf rail 316a and extends in the front-rear direction. The height of the first guide 311 should be such that it does not get caught on the lid portion 15, etc., when the washing tank 50 is pulled out.

[0041] Furthermore, a small storage compartment 33 is detachably provided on the inside of the upper shelf basket rail 316, which extends along the left inner surface of the washing tank 50. However, the placement of the small storage compartment 33 is not limited to the left inner surface of the washing tank 50; it may be placed in any position that is detachable from the upper shelf basket 31 and does not interfere with the basket, such as the right inner surface of the washing tank 50.

[0042] <Regarding auxiliary basket 314> The auxiliary basket 314 is a plate-shaped dish basket formed from a lattice-like frame, on which dishes can be placed. At both ends of the auxiliary basket 314 in the front-rear direction, there are "L"-shaped second sliding parts 315 that extend outwards from the upper shelf rail 316. Of the two sides of the "L" shape, one side extends in the front-rear direction in the Y-axis direction parallel to the auxiliary basket 314, and the other side extends upward in the Z-axis direction. Furthermore, the auxiliary basket 314 is pivotally supported on one side to the left of the fixing wire 318 of the upper shelf basket 31, and is provided to be able to support the basket in an upright position or in a horizontal position tilted towards the right side closer to the upper shelf basket section 319 or to the left side closer to the small item storage compartment 33. The auxiliary basket 314 is pivotally supported by a first sliding wire 317a that connects the first sliding parts 317 provided at both ends of the upper shelf basket 31 in the front-rear direction. Specifically, an elongated hole extending in the front-rear direction is provided on the right side of the auxiliary basket 314 when it is in a horizontal position, and the first sliding wire 317a and the elongated hole are fitted together to pivotally support the auxiliary basket 314 so that it can rotate freely. The first sliding wire 317a is composed of wires extending in the front-rear direction, and multiple wires are provided. In this embodiment, there are two wires, and the ends 317b at both ends of one of the first sliding wires 317a are bent inward from the upper shelf basket rail 316. In addition, the auxiliary basket 314 and the fixing wire 318 are held together and overlap as a single unit when in an upright position (Figures 4 and 5).

[0043] The second sliding part 315 slides on the upper shelf rail 316, specifically on the first upper shelf rail 316a, when the auxiliary car 314 is in a horizontal position. Also, when the auxiliary car 314 is in a horizontal position, the auxiliary car fixing claw 313 is provided protruding upward from near the center of the auxiliary car 314.

[0044] Furthermore, the auxiliary basket 314 allows for stable placement of tableware 6, especially in a horizontal position. Therefore, in order to further improve the stability of the tableware 6, in this embodiment, multiple rows of setting protrusions 314a, which are projections that protrude upward, are arranged in the front-to-back direction on the surface that contacts the set tableware 6. This improves the ease with which the tableware 6 is set on the auxiliary basket 314, and prevents the tableware 6 from shifting position or sliding due to the force of the washing water spray, thereby preventing deterioration of washing performance.

[0045] Furthermore, the auxiliary basket fixing claws 313, like the setting projections 314a, are projections that protrude upward, thus contributing to improved setting of tableware 6 placed on the auxiliary basket 314. This helps to prevent the tableware 6 from shifting position or sliding due to the force of the washing water spray, which can worsen washing performance.

[0046] <Regarding the fixing wire 318> The fixing wire 318 is a wire that extends in the front-rear direction in an upright position above the horizontal auxiliary cage 314 and upper shelf cage rail 316, and is provided between the auxiliary cage 314 and the upper shelf cage section 319.

[0047] The fixing wire 318 is pivotally supported at the ends 317b of the first sliding wire 317a between the auxiliary cage 314 and the upper cage section 319, and is provided so that it can be supported in an upright position (upright state) or in a horizontal position (horizontal state) toward the upper cage section 319. Figures 4 and 5 show the upright state in which the auxiliary cage fixing claw 313 is fixed to the fixing wire 318.

[0048] The upper portions of both ends of the fixing wire 318 are bent so that, when viewed from the front in a vertical position, the fixing wire 318 is tilted more towards the vertical. As shown in Figure 5, this bend contacts the first sliding wire 317a other than the wire with the end 317b, thereby maintaining the fixing wire 318 in a vertical position without tilting horizontally to the left.

[0049] When the fixing wire 318 is in an upright position, low-height tableware 6 such as lunch boxes can be placed between the fixing wire 318 and the bottom surface of the upper shelf basket 31, and can be used as a tableware holder. Furthermore, when the fixing wire 318 is in an upright position, the auxiliary basket fixing claws 313 are configured to fit onto the wires extending in the front-rear direction of the fixing wire 318, so that the fixing wire 318 can hold the auxiliary basket 314 in an upright position.

[0050] <Regarding the upper shelf basket section 319> The upper shelf basket 31 has an upper shelf basket section 319 on the opposite side of the auxiliary basket 314 in the X-axis direction, with a fixed wire 318 extending in the front-rear direction as its center. The upper shelf basket section 319, which is made of wire, specifically has an upper shelf first basket section 319A located on the side of the fixed wire 318, and an upper shelf second basket section 319B which is connected in a planar manner to the upper shelf first basket section 319A on the opposite side of the fixed wire 318.

[0051] The first upper shelf basket section 319A is located adjacent to the fixing wire 318 and consists of a flat wire extending horizontally, forming a space on which tableware can be placed. The second upper shelf basket section 319B, which is continuous with the first upper shelf basket section 319A, is also made of wire, similar to the first upper shelf basket section 319A, and has a recessed area that is indented downwards, forming a space on which tableware such as cups and glasses can be easily placed. Between the first upper shelf basket section 319A and the second upper shelf basket section 319B, there is a tableware support section 321 that extends upward to prevent tableware placed in each space from falling over horizontally and to support the tableware upright. The tableware support section 321 is lower in height than the fixing wire 318 and is made of wire extending in the front-to-back direction. Both ends of the first upper shelf cage section 319A are supported by the ends 317b of the first sliding wire 317a, thereby allowing the first upper shelf cage section 319A and the second upper shelf cage section 319B to rotate together.

[0052] As a result, the upper shelf basket section 319 is configured to be supported in an upright position (upright position) by leaning against the upright fixing wire 318, or in a horizontal position (horizontal position) tilted toward the inner wall of the washing tank 50. The upper shelf basket section 319 and the fixing wire 318 are held together and overlap as a single unit in the upright position.

[0053] With these configurations, the auxiliary basket 314, the upper shelf basket section 319, and the fixing wire 318 can all be held in an upright position, overlapping as a single unit. Conversely, the auxiliary basket 314, the upper shelf basket section 319, and the fixing wire 318 can all be placed in a horizontal position, allowing the entire surface of the upper shelf basket 31 to be uniformly flat.

[0054] The fixed wire 318 and the upper shelf first cage section 319A have elongated support holes 400 formed at both ends. The support holes 400 are inserted so as to pass through the ends 317b of the first sliding wire 317a, thereby pivotally supporting the fixed wire 318 and the upper shelf first cage section 319A with respect to the first sliding wire 317a. When the fixed wire 318 and the upper shelf first cage section 319A are lifted vertically, they move up and down by the length of the longitudinal direction of the support holes 400. In addition, the wires above the support holes 400 at both ends of the fixed wire 318 are bent so that, when viewed from the front in a vertical position, the fixed wire 318 is inclined more vertically than the angle of the support holes 400. When the fixed wire 318 is rotated from a horizontal to a vertical position, as shown in Figure 5, this bend comes into contact with the wire 317a between the first sliding parts, which is on the other side of the wire having both ends 317b, and the fixed wire 318 is maintained in a vertical position without falling to the left horizontally.

[0055] [1-2. Operation] Next, the operation of the upper shelf basket 31 will be explained with reference to Figures 6 to 8.

[0056] Figure 6 is a schematic front view showing the auxiliary car 314 in a horizontal position being moved in the positive X-axis direction. Figure 7 is a schematic front view showing the three steps involved in moving the auxiliary car 314 in a horizontal position in the positive X-axis direction. Figure 8 is a schematic front view showing the two steps involved in moving the auxiliary car 314 in an upright position in the negative X-axis direction.

[0057] <Rotation of the auxiliary basket 314 in conjunction with movement> As shown in Figure 3, when the auxiliary basket 314 and the upper shelf basket section 319 are in a horizontal position, when the auxiliary basket 314 is moved to the left in the positive X-axis direction, as shown in Figure 6, the second sliding section 315 comes into contact with the second guide 312, and the auxiliary basket 314 is lifted upward.

[0058] Starting from the state shown in Figure 6, Figure 7 shows how, as the auxiliary basket 314 moves to the left, it rotates and becomes upright due to the above configuration.

[0059] In Figure 7(a), when the auxiliary basket 314 is in a horizontal position, if the auxiliary basket 314 is moved to the left in the positive X-axis direction, the second sliding part 315 slides along the first upper shelf rail 316a, and then the second sliding part 315 of the auxiliary basket 314 comes into contact with the second guide 312, which is formed in a semicircular shape by a wire that protrudes upward and is provided at the left end of the upper shelf rail 316 that extends along the front and rear inner surfaces of the washing tank 50. As a result, the auxiliary basket 314 is lifted and begins to rotate upward.

[0060] The second guide 312 is provided in conjunction with the protruding structure at the left end of the second upper shelf rail 316b, which is used to demarcate the groove 316c. Therefore, the second guide 312 is formed so that a portion of the second upper shelf rail 316b is positioned above the first upper shelf rail 316a. In this embodiment, the protruding structure for demarcating the groove 316c and the second guide 312 are combined into one structure, but they may also be provided in different positions as separate structures.

[0061] At this time, the protrusion of the second guide 312 is formed in a smooth semicircular shape so that the contact between the second sliding part 315 and the second guide 312 is smooth. Furthermore, it is preferable that the second sliding part 315 is configured to be lower than the height of the upper surface of the auxiliary basket 314 in the horizontal state shown in Figure 3, so that the second sliding part 315 can easily ride up onto the second guide 312. It is also preferable that the width of the second guide in the X-axis direction is shorter than the position of the first guide in the X-axis direction. By configuring the second guide to be short and low, the auxiliary basket 314 is less likely to rotate at a large angle when slid to the left, making it easier to create a wider space for placing dishes.

[0062] Furthermore, the second sliding portion 315 also has a smooth curve in the "L"-shaped bent portion on the side that contacts the second guide 312.

[0063] Subsequently, the second sliding part 315 fully rides up onto the second guide 312, and the auxiliary car 314 lifts up. If the auxiliary car 314 continues to move to the left, first, as shown in Figure 7(b), the left side of the auxiliary car 314 comes into contact with the first guide 311. Then, guided by the first guide 311 which extends upward, the auxiliary car 314 rotates upward, and finally, as shown in Figure 7(c), the left side of the auxiliary car 314 comes into contact with the upper edge of the first guide and becomes upright. At this time, it is even better if the auxiliary car 314 has a guide contact projection 320 on the back surface when it is in a horizontal position. When the auxiliary basket 314 is rotated to an upright position, the guide contact projection 320 rides up so as to contact the upper edge of the first guide 311, preventing the auxiliary basket 314 from hitting and damaging the inner wall of the washing tank 50, and also stably supporting the upright position. Alternatively, the first guide may be configured to be higher than the auxiliary basket 314 in its upright position. In this case as well, the auxiliary basket 314 can rotate to an upright position without damaging the inner wall of the washing tank 50. The upright position of the auxiliary basket 314 may be supported by leaning against the inner wall of the washing tank 50. In this case, the upper basket rail 316 does not need to be equipped with the first guide 311.

[0064] With this configuration, when the user moves the upper shelf basket 31 to the left, the auxiliary basket 314 naturally rotates upward, making it easy to access the lower basket 32. Also, although the movement was described in the order of Figures 7(a), (b), and (c) above, conversely, Figure 7(c) It is also possible to move them in the order of (b) and (a). In this case, simply moving the upper shelf basket 31 in the state shown in Figure 7(c) to the right will cause the auxiliary basket 314 to rotate downwards naturally, allowing the tableware 6 to be placed on the auxiliary basket 314 and the small item container 33. With this specification, there is no need to attach or detach the basket or to hook it onto something to restrict its movement, and the auxiliary basket 314 can be moved in a single action. Furthermore, if the degree of protrusion of the guide contact projection 320 is configured to be small, even when the auxiliary basket 314 is moved in the order of Figure 7(c), (b), and (a), the engagement between the guide contact projection 320 and the first guide 311 will easily disengage, making it possible to rotate it smoothly to a horizontal position.

[0065] Furthermore, in the state shown in Figure 7(c), the auxiliary basket 314 may be configured to be automatically fixed to the fixing wire 318. If this specification is desired, the fixing wire 318 must be in an upright position beforehand, as shown in Figures 7(b) and 7(c). Also, if the auxiliary basket 314 is configured to be automatically fixed to the fixing wire 318, the angle between the auxiliary basket 314 and the fixing wire 318 in the state shown in Figure 7(c) can be adjusted so that the auxiliary basket fixing claws 313 and the fixing wire 318 engage smoothly, or the width of the claws of the auxiliary basket fixing claws 313 can be made wider, allowing the auxiliary basket 314 to be automatically fixed to the fixing wire 318 in a single action. To prevent the fixing wire 318 from rotating to the right even when subjected to the reaction force of the auxiliary basket 314, the shape of the pivot hole 400 of the fixing wire 318 can be configured such that it catches on the first sliding wire 317a when the auxiliary basket 314 rotates to the right, thereby making it easier to automatically fix the auxiliary basket and the fixing wire 318. Alternatively, by configuring the fixing wire 318 to rotate to the left and not to rotate to the right, the auxiliary basket and the fixing wire 318 can be easily fixed automatically.

[0066] <Regarding the movement of the upper shelf basket 31 while a portion of it is fixed to the fixing wire> Figure 8 is a schematic front view of the two steps involved in moving the upright auxiliary car 314 in the negative X-axis direction. At this time, the auxiliary car 314 is fixed to the fixing wire 318 by the auxiliary car fixing claws 313 and held in an upright position.

[0067] When the auxiliary basket 314 and the fixing wire 318 are fixed in an upright position, the upper shelf basket 31 can be moved in the X-axis direction without releasing the fixing. This configuration allows for easy access to the lower basket 32 ​​while placing tableware 6 in a portion of the space of the upper shelf basket 31.

[0068] Furthermore, if the auxiliary basket 314 and the fixing wire 318 are manually fixed in the state shown in Figure 7(c), or if they are automatically fixed as described above, the user can access the lower left side of the auxiliary basket 314 with one hand by simply moving it in the manner shown in Figures 8(a) and (b).

[0069] This movement is also the same when the auxiliary basket 314, the upper shelf basket section 319, and the fixing wire 318 are held in an upright position, overlapping as a single unit.

[0070] Furthermore, although [1-2. Operation] described the auxiliary basket 314 as being moved in the left-right direction, any component can be moved in the same way as long as it is connected to the first sliding part 317. For example, even if the fixing wire 318 or the upper shelf basket part 319 is grasped and moved, it can similarly slide along the upper shelf basket rail 316 and move left-right.

[0071] <Regarding the attachment of the auxiliary basket to the rotating wire, the attachment of the upper shelf basket, and movement in that state> As shown in Figures 4, 5 and 8, the first sliding part 317 is slidably fitted into the groove 316c of the upper shelf basket rail 316, so that the upper shelf basket 31 is above the lower basket 32 ​​in the dishwasher. It is configured to allow for lateral movement in the left-right direction.

[0072] Here, the upper shelf rail 316 restricts the range of movement of the upper shelf 31 by adjusting the length of the groove 316c. Specifically, the left end of the groove 316c is defined by a second guide 312, which is formed by raising a portion of the upper shelf rail 316 upwards to a height greater than the horizontal extension of the upper shelf rail 316. Conversely, the right end of the groove 316c is restricted by forming a divider 322, which is formed by raising a portion of the upper shelf rail 316 upwards to a height greater than the horizontal extension of the upper shelf rail 316. With this configuration, the movement of the first sliding portion 317 is restricted near its left and right ends, preventing it from detaching from the upper shelf rail 316 or colliding with the inner wall of the washing tank 50.

[0073] [1-3. Effects, etc.] As described above, in this embodiment, the dish rack 30 has an auxiliary basket 314 on which dishes can be placed. The auxiliary basket 314 is pivotally supported on the upper shelf basket 31 and can be held on the upper shelf basket 31 in an upright or tilted position. A part of the upper shelf basket 31 is configured to be movable laterally, and when the auxiliary basket 314 is tilted, if a part of the upper shelf basket 31 moves laterally toward one inner surface of the upper shelf basket 31, the auxiliary basket 314 can rotate to an upright position.

[0074] This allows for more efficient use of the dish rack space, enabling more dishes to be placed inside. Furthermore, it allows for one-action access to the area below, reducing effort and improving usability.

[0075] As in this embodiment, the auxiliary basket 314 may be configured to be fixed in an upright position on the upper shelf basket 31 by fixing a portion of it to the upper shelf basket 31.

[0076] This allows the auxiliary basket 314 to be kept upright, making it easier to access the area below and improving usability.

[0077] As in this embodiment, the upper shelf basket 31 has a fixing wire 318 that supports the tableware 6 placed on the upper shelf basket 31. The fixing wire 318 is made of a horizontally extending wire at a position above the tilted auxiliary basket 314, and the auxiliary basket fixing claws 313 of the auxiliary basket 314 fit onto the fixing wire 318, thereby enabling the upper shelf basket 31 to be fixed in an upright position.

[0078] This allows the auxiliary basket 314 to be kept upright, making it easier to access the area below and improving usability.

[0079] As in this embodiment, the upper shelf basket 31 has an upper shelf basket rail 316 provided along the inner surface of the washing tank 50, and a part of the upper shelf basket 31 is configured to be movable laterally along the upper shelf basket rail 316, and when the upper shelf basket 31 moves laterally toward one inner surface inside the washing tank 50 with the auxiliary basket 314 in a tilted position, the auxiliary basket 314 may be configured to rotate to an upright position while contacting a guide provided on the upper shelf basket rail 316.

[0080] This allows the auxiliary basket 314 to be smoothly rotated to an upright position.

[0081] As in this embodiment, the auxiliary basket 314 is provided with second sliding parts 315 that protrude outward at both opposite sides, and the second sliding parts 315 are arranged to slide on the upper shelf basket rail 316 when the auxiliary basket 314 is tilted, and when the upper shelf basket 31 moves laterally toward one inner surface inside the washing tank 50 with the auxiliary basket 314 tilted, the second sliding parts 315 The configuration may also involve contact with the guide.

[0082] This allows the auxiliary basket 314 to reach the guide for rotating it simply by moving it laterally.

[0083] As in this embodiment, the guide has a first guide 311 and a second guide 312. The first guide 311 is configured to protrude upward from the upper basket rail 316 and extend horizontally along the inner surface of one of the washing tanks 50 of the dishwasher 1 in the direction in which the upper basket 31 moves laterally. When the auxiliary basket 314 moves laterally toward one of the inner surfaces inside the washing tank 50, the auxiliary basket 314 may rotate until it is in an upright position, with its side surface in contact with the first guide 311.

[0084] This allows the auxiliary basket 314 to be rotated smoothly to an upright position without damaging the inner wall of the washing tank 50.

[0085] As in this embodiment, the second guide 312 is formed in a semicircular shape by a wire that protrudes upward, provided at the corners closest to the first guide 311, at both ends of the rails on both sides of the upper shelf rail 316 adjacent to the rail on which the first guide 311 is provided. The second guide 312 is provided closer to the center of the washing tank 50 than the first guide 311. When the auxiliary basket 314 moves laterally toward one inner surface inside the washing tank 50, the second sliding part 315 slides on the upper shelf rail 316 and then comes into contact with the second guide 312, causing the second sliding part 315 to be lifted upward and the auxiliary basket 314 to begin rotating.

[0086] As a result, when the auxiliary basket 314 is moved sideways, it can begin to rotate smoothly without the user having to lift it.

[0087] As in this embodiment, when the auxiliary basket 314 moves laterally toward one inner surface inside the washing tank 50, the second sliding part 315 slides along the upper shelf basket rail 316 and comes into contact with the second guide 312, lifting the auxiliary basket 314 upward. Then, the side of the auxiliary basket 314 comes into contact with the first guide 311 as it rotates upward, guiding the auxiliary basket 314 to an upright position.

[0088] As a result, when the auxiliary basket 314 is moved sideways, it can rotate smoothly to an upright position without the user having to lift it.

[0089] As in this embodiment, the auxiliary basket 314 may be configured such that, starting from an upright position in contact with the first guide 311, it moves laterally toward the other inner surface within the washing tank 50, causing the side of the auxiliary basket 314 to rotate downward while in contact with the first guide 311. As the rotation progresses, the second sliding part 315 comes into contact with the second guide 312, and finally the auxiliary basket 314 is guided to a position where it is lying down on the upper shelf basket rail 316.

[0090] This allows the upright auxiliary basket 314 to rotate smoothly to a horizontal position when moved sideways to the opposite side.

[0091] As in this embodiment, the auxiliary basket 314 may be configured to have multiple upward-projecting protrusions on the surface that contacts the set tableware 6.

[0092] This improves the stability of the dishes 6 placed on the auxiliary basket 314, preventing them from shifting position or sliding, which can worsen washing performance.

[0093] As in this embodiment, the dishwasher 1 may be configured to include a washing tank 50 and a dish basket 30, and the dish basket 30 may be configured to include an upper basket 31 and a lower basket 32 ​​that are arranged vertically within the washing tank 50 and on which the dishes 6 are placed.

[0094] This allows the auxiliary basket 314 to be easily stored with minimal effort, and the lower basket 32 ​​to be easily accessed.

[0095] (Other embodiments) As described above, Embodiment 1 has been explained as an example of the technology disclosed in this application. However, the technology in this disclosure is not limited to this and can be applied to embodiments that have been modified, replaced, added, or omitted. Furthermore, it is possible to create new embodiments by combining the components described in Embodiment 1 above.

[0096] Therefore, other embodiments are illustrated below.

[0097] The dish rack 30 is provided with an upper shelf basket 31 and a lower basket 32 ​​arranged vertically within the washing tank 50, and it has been explained that each basket can be used according to its purpose. However, the configuration of the dish rack is not limited to this. For example, in addition to the upper shelf basket 31 and the lower basket 32, there may also be a middle basket, and a configuration in which a part of the dish rack moves laterally may be provided in the middle basket or the lower basket 32.

[0098] Furthermore, although it was explained that the auxiliary basket 314 is pivotally supported on the upper shelf basket 31, the location to which the auxiliary basket 314 is pivotally supported is not limited to the upper shelf basket 31. The auxiliary basket 314 only needs to be able to hold dishes, allow for storage with minimal movement, or provide easy access to the area below, so it may be provided on, for example, the middle basket or the lower basket. Therefore, in this embodiment, the upper shelf basket may be read as the dish basket.

[0099] In Embodiment 1, the upper shelf basket 31 comprises an upper shelf basket rail 316, a rotatable auxiliary basket 314, an upper shelf basket section 319, and a fixing wire 318. It was also explained that the basket section, which is part of the upper shelf basket 31 and consists of the auxiliary basket 314 and the upper shelf basket section 319, and the fixing wire 318 are configured to move laterally. However, this is just one example. For example, the basket section of the upper shelf basket 31 does not have to have an upper shelf basket section 319, and the upper shelf basket section 319 does not have to have a rotation mechanism. Furthermore, it may have other baskets regardless of whether or not it has a rotation mechanism. In other words, the configuration of the upper shelf basket 31 only needs to be such that the auxiliary basket 314 is laterally movable and can rotate to an upright position when moved laterally.

[0100] In Embodiment 1, the auxiliary basket 314 was described as being composed of a plate-shaped grid frame and sliding on the upper shelf basket rail 316, but this is just one example. The auxiliary basket 314 may be configured to be foldable in a predetermined position. This allows for effective use of the space in the upper shelf basket 31 when there are only a few dishes, while maintaining access to the lower basket. Furthermore, if the auxiliary basket 314 is rotatable when folded, the height extending above the first guide can be reduced.

[0101] Furthermore, the auxiliary basket 314 may be configured in two layers, upper and lower. With a two-layer structure, the dish setting area of ​​the auxiliary basket 314 can be adjusted by sliding out and storing one side. In such a configuration, either each of the two layers of auxiliary basket 314 can be configured to rotate toward the fixing wire 318, or the two layers of auxiliary basket 314 are connected and one of the auxiliary baskets 314 can be configured to rotate toward the fixing wire 318, thereby making effective use of the space in the upper basket and allowing more dishes to be set, as well as enabling access to the lower basket in a single action.

[0102] In Embodiment 1, the upper shelf basket section 319 has a dish resting support section 321 and an upper shelf second basket section 319B that is connected to the upper shelf first basket section 319A in a planar manner. The upper shelf second basket section 319B is constructed of wire material, similar to the upper shelf first basket section 319A, and has a recess that is indented downwards. However, this is just one example. The upper shelf first basket section 319A and the upper shelf second basket section 319B may be constructed flat, or they may be formed from a single basket. In this case, the dish resting support section 321 may not be included.

[0103] In Embodiment 1, the convex configuration at the end for separating the second guide 312 and the groove 316c was configured such that the second upper shelf rail 316b is convex upward at its left-right ends compared to the first upper shelf rail 316a, but this is just one example. A portion of the first upper shelf rail 316a may also be configured to be convex upward to form a convex configuration for separating the groove 316c or the second guide 312.

[0104] Furthermore, although it was explained that the protrusion of the second guide 312 is formed in a smooth semicircular shape, this is just one example. The second guide 312 may be configured in a roughly triangular shape with a sloping hypotenuse on its upper side so that the second sliding part 315 is smoothly guided to the first guide 311. In addition, if the second guide 312 is configured in a roughly triangular shape, the width of the second guide 312 in the X-axis direction may extend to the same position as the first guide 311. With such a configuration, the auxiliary basket 314 is guided to the first guide 311 more smoothly.

[0105] Furthermore, in Embodiment 1, the auxiliary basket 314 is configured to have multiple rows of setting protrusions 314a, which are projections that protrude upward, arranged in the front-to-back direction on the surface that contacts the set tableware 6, but this is just one example. The setting protrusions 314a may be provided in the left-to-right direction instead of the front-to-back direction, or they may be arranged at random positions. Also, the setting protrusions 314a do not have to be projections. For example, a step can be formed with the grid of the auxiliary basket 314, which can be used as an alternative to the setting protrusions 314a. Moreover, it is not necessary to provide the setting protrusions 314a at all.

[0106] The embodiments described above are for illustrative purposes only and may be modified, replaced, added, or omitted within the scope of the claims or equivalents thereof.
