Embodiments for Carrying Out the Invention

[0015] (Findings etc. underlying the present disclosure) When the inventors arrived at the idea of the present disclosure, in a dishwasher according to the prior art, when a light object to be washed that is easily blown away, such as a silicone cup, is placed in a dish basket, the jet output from the washing nozzle 5 is strong and it will be blown away during the washing process, so these small items were considered not washable. On the other hand, a dishwasher equipped with a small basket that can store and wash light objects to be washed that are easily blown away as shown in FIG. 8 has been proposed (see Patent Document 2). FIG. 8 is a perspective view showing a small basket attached in front of a dish tray that constitutes the dish basket body 9. By storing and washing light objects to be washed that are easily blown away in the storage space formed by this small basket, the objects to be washed can be washed more effectively.

[0016] However, in a dishwasher equipped with a dish basket as shown in FIG. 8 described above, an extra space is required in front of the dish basket to attach the small basket which is a separate member. Therefore, the inventors discovered that there is a problem that this configuration cannot be adopted in a small-capacity dishwasher, and in order to solve that problem, they arrived at the constitution of the subject of the present disclosure.

[0017] Therefore, the present disclosure provides a dishwasher having a dish basket configured to form a storage space for storing light objects to be washed that are easily blown away by a foldable upper shelf of the dish basket and the inner side surface of the washing tank, and enabling these objects to be washed without falling off.

[0018] Hereinafter, embodiments will be described in detail with reference to the drawings. However, a more detailed description may be omitted. For example, detailed descriptions of matters already well known, or duplicate descriptions of substantially the same configuration may be omitted.

[0019] The attached drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0020] The dishwasher according to the present invention includes a washing tub provided in the dishwasher main body and having an opening at the front, and a dish basket for placing dishes arranged in the washing tub. The dish basket is configured in multiple stages by pivotally supporting upper shelves on the inner side surface of the washing tub or the back surface of the basket body. The dish basket body can be pulled out forward from the opening. Further, the upper shelf is composed of a plurality of dish baskets having recesses and can be folded toward the rear surface of the washing tub. When the upper shelf is supported in a substantially horizontal direction, normal dishes can be placed in the recesses. When the upper shelf is rotated toward the rear surface of the washing tub and supported in a substantially vertical direction, a new storage space for dishes is formed between the inner side surface of the washing tub or the back surface of the dish basket body and the recesses, and light objects to be washed that are easily splashed can be stored and washed.

[0021] Also, in the drawings, substantially the same members are denoted by the same reference numerals.

FIG. 7 is a side sectional view showing the configuration of a conventional dishwasher 20. FIG. 8 is a schematic perspective view showing the configuration of a dish basket main body 9 provided with a small basket 12, which is arranged in a conventional dishwasher 20.

[0023] Hereinafter, in the front view of the dishwasher 20 shown in the drawings, the +X direction is from left to right, the depth direction is the +Y direction, and the vertically upward direction is the +Z direction for explanation.

[0024] The dishwasher 20 of the present embodiment includes, at least in FIG. 1, a main body 1, a washing tub 2 housed in the main body 1, a dish basket main body 9 on which objects to be washed such as tableware are placed, an upper shelf 10 of the dish basket disposed above the washing tub 2, and washing nozzles 5 and tower nozzles 6 which are washing units.

[0025] The dish basket main body 9 is arranged on the rails on the inner surface of the washing tub 2 so as to be pullable in the -Y direction or pushable in the +Y direction with respect to the washing tub 2.

[0026] As shown in FIGS. 1 to 5, the upper shelf 10 of the dish basket is attached to the inner surface of the washing tub 2 or the back surface of the dish basket main body 9 via a shaft portion 13 that is rotatable in the pulling direction (-Y direction) or the pushing direction (+Y direction) of the dish basket main body 9.

[0027] The dish basket upper shelf 10 is composed of a plurality of strip members, which are pivotally supported and configured in multiple stages. The dish basket upper shelf 10 forms a concave portion 14 by bending the strip members, and dishes can be placed on the concave portion 14.

[0028] Here, as shown in Fig. 5(a) in a side view, the concave portion 14 is formed in an inverted triangle shape in a state where the dish basket upper shelf 10 is supported substantially horizontally.

[0029] The cleaning nozzle 5 is disposed in the cleaning tank 2 and sprays cleaning water onto an object to be cleaned such as dishes placed on the dish basket 8 to clean the object to be cleaned.

[0030] The tower nozzle 6 is provided on the inner side surface of the cleaning tank 2, particularly on the inner side surface close to the back surface of the dish basket main body 9 in this embodiment. Similar to the cleaning nozzle 5, it sprays cleaning water and can clean an object to be cleaned such as the placed dishes.

[0031] That is, according to the dishwasher 20 of the present embodiment, a light object to be cleaned that is easily splashed is stored in the storage space formed by the inner side surface of the cleaning tank 2 or the back surface of the dish basket main body 9 and the dish basket upper shelf 10 attached thereto. Thereby, the object to be cleaned can be cleaned more reliably and efficiently without the light object to be cleaned being splashed.

[0032] Particularly when the dish basket upper shelf 10 is provided on the back surface of the dish basket main body 9, the object to be cleaned placed on the dish basket upper shelf 10 can be more effectively cleaned by the cleaning water sprayed from the tower nozzle 6 provided on the inner side surface of the cleaning tank 2 in addition to the cleaning nozzle 5 that sprays cleaning water from the bottom surface of the dish basket main body 9.

[0033] The tower nozzle 6 has injection ports 6a and 6b for spraying cleaning water. Here, the injection port 6a is disposed in the upper stage and the injection port 6b is disposed in the lower stage. At this time, the injection ports 6a and 6b are opened upward, and the cleaning water can be sprayed upward or obliquely upward.

[0034] In addition to the injection ports 6a and 6b, there are also those with a horizontally opened port for cleaning the wall, those with a downward-facing port, those with a narrowed width of the injection port to enhance the injection force, and so on.

[0035] Hereinafter, the members constituting the dishwasher 20 will be described with reference to FIGS. 1 to 5.

[0036] The main body 1 constitutes the outer shell of the dishwasher 20 and houses the washing tub 2 inside. Note that the main body 1 may be built-in, for example, under the kitchen countertop. Also, the main body 1 may constitute the main body of a type of dishwasher that can be independently placed on the countertop.

[0037] In FIG. 3, the dish basket main body 9 places objects to be washed such as tableware. The dish basket main body 9 is arranged so that it can be pulled out to the front side (-Y direction) or pushed into the rear side (+Y direction) of the washing tub 2 along rails provided on the inner side surface of the washing tub 2, for example. Hereinafter, when simply described as the "pull-out direction", it includes both the +Y direction and the -Y direction.

[0038] Also, a dish basket upper shelf 10 is arranged above the washing tub 2. As shown in FIG. 1, the dish basket upper shelf 10 is attached to the inner side surface of the washing tub 2 or the back surface of the dish basket main body 9 at a position above such that the dishes placed on the dish basket main body 9 cannot reach.

[0039] Note that the dish basket upper shelf 10 is composed of two parts, the dish basket upper shelf right 101 and the dish basket upper shelf left 102, and these are each individually rotatable.

[0040] [2. Detailed Configuration of the Dish Basket Upper Shelf 10] Hereinafter, the detailed configuration of the dish basket upper shelf 10 will be described with reference to FIGS. 3 to 5.

[0041] As shown in FIGS. 4 and 5, the upper shelf 10 of the dish basket is composed of a plurality of strip members, and a plurality of pins are provided in the concave portions of these strip members. Further, it is pivotally supported by fitting the strip members so as to be rotatable, and is configured in a plurality of stages. At this time, the upper shelf 10 of the dish basket rotates via a shaft portion 13 provided near the center in the left - right width of the upper shelf 10 of the dish basket. This shaft portion 13 is configured in a hook shape curved like an inverted U, and the strip members of the upper shelf 10 of the dish basket are passed through this hook and pivotally supported.

[0042] The upper shelf 10 of the dish basket further has a concave portion 14 formed by bending the strip members, and dishes can be placed on the concave portion 14.

[0043] Here, the concave portion 14 is formed to be an inverted triangle in a side view in a state where the upper shelf 10 of the dish basket is supported substantially horizontally (open state) as shown in FIG. 5(a). At this time, the concave portion 14, which is a part of the rotating basket, abuts against a horizontal support pin 16 fixed to the inner side surface of the washing tub 2 and protruding horizontally in the - Y direction, thereby supporting the open state. Also, when the inverted triangle formed by the concave portion 14 has two hypotenuses in a side view as shown in FIG. 5(a), in a perspective view as shown in FIG. 4, the concave portion 14 has two inclined surfaces.

[0044] In the concave portion 14, on the hypotenuse on the inner side surface side (+Y direction side) of the washing tub 2 among the two hypotenuses of the above - mentioned inverted triangle, a large support pin 15 for propping up the object to be washed is provided near the center of the hypotenuse. Also, a plurality of them are provided in a straight line in the left - right direction (X - axis direction) over the entire inclined surface of the concave portion 14. By this large support pin 15, when placing an object to be washed such as a cup, it is possible to support the object to be washed so that it does not fall. Also, by providing the large support pin 15, it is possible to suppress the object to be washed from rolling in the left - right direction (X - axis direction) and to perform positioning. Thereby, the object to be washed can be stably washed at a fixed position.

[0045] In the recess 14, on the hypotenuse on the central side (-Y direction side) of the two hypotenuses of the aforementioned inverted triangle in the cleaning tank 2, near the end of the hypotenuse, there is provided a small support pin 17 for abutting the object to be cleaned. Also, on the entire slope of the recess 14, a plurality of them are provided in a straight line in the left-right direction (X-axis direction). By means of this small support pin 17, especially when placing an object to be cleaned such as a cup, it is possible to abut the object to be cleaned and prevent the object to be cleaned from being placed in a state of contacting the entire hypotenuse. At this time, since the object to be cleaned abuts and is supported only by a plurality of small support pins 17 as shown in FIG. 4, the installation area is smaller compared to the state of contacting the entire hypotenuse, and it is placed at an angle. Thereby, drying of the object to be cleaned can be promoted. Also, when the object to be cleaned is dried, it is possible to prevent the object from drying with the trace of the hypotenuse remaining.

[0046] The large support pin 15 and the small support pin 17 are not provided on the central strip in the left-right direction (X-axis direction) among the strips forming the inclined surface of the inverted triangle in the recess 14. Therefore, the inclined surfaces of the recess 14 of the upper shelf right 101 and the upper shelf left 102 of the tableware basket are formed using four types of strips: a strip 151 with a large support pin, a strip 152 without a large support pin, a strip 171 with a small support pin, and a strip 172 without a small support pin. Although the position where the strip without a support pin is provided is not defined, by providing the strip without a support pin in the center in the left-right direction, when two objects to be cleaned are placed side by side on the upper shelf 10 of the tableware basket, even objects to be cleaned with different diameters can be placed without the support pins getting in the way and can be cleaned simultaneously. Also, in the case of an object to be cleaned with a large diameter, it can be placed without the support pins getting in the way.

[0047] As shown in FIG. 5(c), in a state where the upper shelf 10 of the tableware basket is supported substantially vertically (closed state), the recess 14, a part of the rotatable basket, the vertical support hook 18, is fixed from the inner surface of the cleaning tank 2 and hooked on a vertical support pin 19 protruding toward the center of the cleaning tank 2, supporting the closed state. This vertical support hook 18 has a hook shape curved like the tip of an S-shaped hook. It is formed in a [specific shape]. Further, the protruding vertical support pin 19 is formed in an inverted U shape or a conical shape, and the U-shaped curved portion or the conical right-angled portion protrudes in the central direction of the washing tank 2, that is, in the -Y direction or / and the +Z direction. Therefore, the vertical support hook 18 can be hooked on the vertical support pin 19, supporting the closed state of the recess 14. In the present embodiment, the vertical support pin 19 protrudes in an obliquely upward direction between the -Y direction and the +Z direction. Of course, the direction of this protrusion is not defined as obliquely upward, and any direction in which the vertical support hook 18 can be hooked is acceptable.

[0048] [3. Operation] The upper shelf 10 of the tableware basket in the present embodiment can take two states described below. Specifically, the upper shelf 10 of the tableware basket can select two states: (1) a horizontal state in which tableware can be placed, and (2) a small basket state in which an accommodation space is formed.

[0049] Hereinafter, with reference to FIGS. 5(a) to 5(c), the two states will be described in more detail.

[0050] [3-1. Open state where tableware can be placed] The open state where tableware can be placed refers to a state in which the upper shelf 10 of the tableware basket is supported substantially horizontally. As shown in FIG. 5(a), the upper shelf 10 of the tableware basket is opened in the horizontal direction via the shaft portion 13. At this time, the upper shelf 10 of the tableware basket is fixed by the inner surface of the washing tank 2 or a part of the tableware basket main body 9 so as to maintain the horizontal direction.

[0051] Thereby, the upper shelf 10 of the tableware basket can wash the tableware while stably holding it by the recess provided on its upper surface. In the embodiment, as described above, the open state is supported by the horizontal support pin 16 protruding horizontally from the inner surface of the washing tank 2.

[0052] When the upper shelf 10 of the dish basket is in the open state like this, the objects to be washed are placed by being propped up against the inclined surface of the recess 14, so they can be washed in an inclined state. Therefore, it is possible to wash particularly objects such as cups and lunch boxes that need to be washed inside the recess. Also, since there is little restriction in the Z-axis height direction, objects with a certain height can also be washed.

[0053] Also, when the upper shelf 10 of the dish basket is in the open state, the objects to be washed placed on the upper shelf 10 of the dish basket can be effectively washed by the washing water sprayed from the upward injection port 6b arranged particularly at the lower stage of the tower nozzle 6. At this time, since it is sprayed from a position below the upper shelf 10 of the dish basket, even objects to be washed placed face down can be washed. Of course, it is also washed by the washing water sprayed from the washing nozzle arranged on the bottom surface of the washing tank 2.

[0054] [3-2. Closed state forming the accommodation space] The closed state forming the accommodation space refers to a state in which the upper shelf 10 of the dish basket is supported substantially vertically, forming a small basket capable of storing the objects to be washed. That is, as shown in Fig. 5(b), the upper shelf 10 of the dish basket is rotated in the direction of pulling out the dish basket via the shaft portion 13, and as shown in Fig. 5(c), a small basket capable of storing the objects to be washed inside is formed by the inner surface of the washing tank 2 and the recess 14 of the upper shelf 10 of the dish basket. At this time, the upper shelf 10 of the dish basket is fixed so as to maintain the vertical direction by a part of the inner surface of the washing tank 2 or the dish basket main body 9. Also, instead of the inner surface of the washing tank 2, a small basket may be formed by the back surface of the dish basket main body 9. In the embodiment, as described above, the closed state is supported by the vertical support hook 18 having a curved hook shape and the vertical support pin 19 protruding from the inner surface of the washing tank 2 toward the center of the washing tank.

[0055] When the upper shelf 10 of the dish basket is in the closed state like this, the objects to be washed are placed in the small basket formed between the inside of the recess 14 and the inner surface of the washing tank 2, so the movement is restricted only inside the small basket Therefore, small items like cookie cutters and lightweight items like silicone cups can be washed. Also, since the distance between the upper shelf 10 of the dish basket and the inner surface of the washing tub 2 is narrow, the items to be washed are less likely to fall.

[0056] Further, when the upper shelf 10 of the dish basket is in the closed state, the items to be washed placed on the upper shelf 10 of the dish basket can be effectively washed by the washing water jetted from the upward jet orifice 6a disposed particularly in the upper stage of the tower nozzle 6. At this time, a part of the washing water jetted from the jet orifice 6a is configured to hit the inner surface ceiling of the washing tub 2, and the items to be washed can be washed by dripping the washing water from the ceiling. Of course, they are also washed by the washing water jetted from the washing nozzles disposed on the bottom surface of the washing tub 2.

[0057] As described above, according to the presence or absence of lightweight items to be washed that are splashed during washing, an appropriate state can be selected from the above two states, and the items to be washed can be washed more reliably.

[0058] Since the upper shelf 10 of the dish basket is divided into two parts, the upper shelf right 101 and the upper shelf left 102 of the dish basket, the above-described open state and closed state can be fixed for each. Therefore, for example, when only two cups are to be washed, only the upper shelf right 101 of the dish basket is opened and the cups are placed, and the upper shelf left 102 of the dish basket is stored in the closed state, so that the space below the upper shelf left 102 of the dish basket is not restricted in height and can be effectively utilized for washing other items to be washed.

[0059] Also, although not particularly mentioned in this embodiment, a drying part for drying the washed dishes, which is provided in a normal dishwasher, may be provided.

[0060] Also, the dish basket of this embodiment may be mounted on a type of dish dryer that does not have a washing function. That is, it may be mounted on a type of dish dryer that includes a drying part and blows air to dry the dishes in the washing tub.

[0061] In the present disclosure, appropriate combinations of any of the various embodiments described above are included. Even with these combinations, the effects of each embodiment can be similarly achieved.

[0062] [4. Effects, etc.] As described above, according to the invention described in claim 1 of the present invention, the dishwasher main body has a washing tub having an opening at the front and a dish basket for placing dishes in the washing tub. The dish basket is composed of a dish basket main body and an upper shelf pivotally supported behind the washing tub and having a recess on which dishes can be placed. Since the upper shelf can be folded toward the back surface of the washing tub, it can be used as a dish basket for placing ordinary dishes in the recess of the upper shelf, and in the state where the upper shelf is folded, a storage space for dishes is formed by the inner surface of the washing tub or the back surface of the dish basket main body and the recess of the upper shelf, and it is possible to properly distinguish between using it as a small basket for storing easily-flying and light objects to be washed. Also, even with a small-capacity washing tub, it is possible to stably wash easily-flying and light objects to be washed.

[0063] Further, according to the invention described in claim 2, since the upper shelf is configured to be fixable in a substantially vertical direction of the dish placement surface in the folded state, it is possible to stably hold the small basket state. Also, by fixing the upper shelf in the folded state, it becomes possible to easily place tall dishes and the like in the space below the upper shelf in the dish basket main body without the upper shelf getting in the way.

[0064] Further, according to the invention described in claim 3, since the upper shelf has a smaller area in plan view than the dish basket main body it becomes possible to easily place dishes without the upper shelf getting in the way even when it is desired to place tall dishes on the dish basket main body. Also, it is possible to properly distinguish between using the dish basket main body and the dish basket upper shelf according to the height and size of the dishes.

[0065] Further, according to the invention described in claim 4, when the upper shelf is pivotally supported on the inner side surface of the washing tub, only the tableware basket body can be pulled out from the opening in front of the washing tub, and when the upper shelf is pivotally supported on the back surface of the tableware basket body, it is configured to be pullable as a unit. This allows tableware placed on the upper shelf and the tableware basket body to be taken out more easily, improving usability.

[0066] As described above, embodiments have been described as examples of the technology disclosed in this application. However, the technology in this disclosure is not limited to this, and can also be applied to embodiments with changes, replacements, additions, omissions, etc. Further, it is also possible to combine the components described in the above Embodiment 1 to form a new embodiment.

[0067] Therefore, other embodiments will be exemplified below.

[0068] (Embodiment 2) Hereinafter, other embodiments regarding the arrangement of the tableware basket will be exemplified.

[0069] In Embodiment 1, as an example, the case where the upper shelf 10 of the tableware basket is provided on the back surface of the tableware basket body 9 has been described. However, it is not limited to this example. It is only necessary that the object to be washed placed on the upper shelf 10 of the tableware basket be washed. Therefore, the arrangement of the upper shelf 10 of the tableware basket is not specified as long as it is within the washing tub 2. For example, the upper shelf 10 of the tableware basket may be arranged on the inner side surface in the X-axis direction. In this case, if the tower nozzle 6 is also arranged on the inner side surface near the upper shelf 10 of the tableware basket, the washing efficiency can be further improved. Also, as a configuration, nozzles may be newly provided on the front side (-Y direction side) or the inner side surface in the X-axis direction separately from the tower nozzle 6.

[0070] Also, the bottom area of the upper shelf of the tableware basket itself may be enlarged to about the size of the tableware basket body 9, and the tableware basket may be rotatable only on the front side (-Y direction side). Also, similar to Embodiment 1, it may be rotatable only on the back side (+Y direction side) of the tableware basket body. In this case, since the objects to be washed can be placed on the entire upper space, a large amount of objects to be washed can be washed at once.

[0071] (Embodiment 3) Hereinafter, other embodiments regarding the configuration of the dish basket upper shelf 10 will be exemplified.

[0072] In Embodiment 1, as an example, it was described that the concave portion 14 is formed in an inverted triangle shape in a state where the dish basket upper shelf 10 is supported substantially horizontally. However, not limited to this example, the concave portion 14 only needs to be able to place and store tableware. Therefore, in a side view, the concave portion 14 may have a shape other than an inverted triangle, such as a rectangle or a semicircle. Thereby, the storage space of the dish basket upper shelf 10 can be widened, the placement stability can be enhanced, and the design can also be improved.

[0073] Also, the dish basket upper shelf 10 may be attached to the inner surface of the washing tub 2 or the back surface of the dish basket main body 9. Therefore, the attachment position of the dish basket upper shelf 10 may not be at an upper position, but may be near the center or the bottom surface. The lower the height, the larger and taller objects to be washed can be stored in the dish basket upper shelf 10 and washed.

[0074] The dish basket upper shelf 10 is divided into two parts, the right dish basket upper shelf 101 and the left dish basket upper shelf 102, and the above-described open state and closed state can be fixed in each part, but it is not limited to this example. It may be divided into three parts instead of two parts, or, for example, as shown in FIG. 6, the dish basket upper shelf 10 may be integrated without being divided into two parts. Thereby, objects to be washed with a certain length can be accommodated in the dish basket upper shelf 10.

[0075] In Embodiment 1, the large support pins 15 and the small support pins 17 are not provided on the central strip in the left - right direction (X - axis direction). Therefore, the slopes of the recess 14 between the right upper dish basket 101 and the left upper dish basket 102 are formed using four types of strips: the strip 151 with large support pins, the strip 152 without large support pins, the strip 171 with small support pins, and the strip 172 without small support pins. However, this is not limited to this example. For example, the strip without support pins can be eliminated, and support pins can be provided on all the strips forming the inverted - triangular slope in the recess 14. In this case, it becomes easier to place small - diameter objects to be washed, and it also becomes easier to restrict the movement of the objects to be washed in the X - axis direction. Or the strip without support pins can be provided at a position other than the center.

[0076] Also, the upper dish basket 10 may be removable. If the upper dish basket 10 can be placed at a preferred position, it can be changed according to the specifications of the user depending on the size and height of the objects to be washed.
