Description

Technical Field

[0001] The present invention relates to a dishwasher including a washing tub in which a dish basket for supporting dishes is stored, a washing nozzle provided in the washing tub, and a washing pump for supplying washing water in the washing tub to the washing nozzle.

Background Art

[0002] Conventionally, as this type of dishwasher, the washing nozzle has a center nozzle extending upward at the center of the washing tub. As a dish basket, a lower basket disposed at the lower part of the washing tub and an upper basket disposed at the upper part of the washing tub and separated from the center nozzle in a plan view are provided (see, for example, Patent Document 1). In this case, with one of the depth direction and the width direction of the washing tub as the X-axis direction and the other as the Y-axis direction, the upper basket is supported by support portions provided on the inner surfaces of the side wall portions on one side and the other side in the Y-axis direction of the washing tub. The first dish support portion that is arcuately curved and extends in a direction opposite to the center nozzle in the X-axis direction at the center portion in the Y-axis direction rather than at both ends in the Y-axis direction in a plan view between the two supported frame portions, and adjacent to the first dish support portion in the X-axis direction, and has a second dish support portion that is arcuately curved and extends along the first dish support portion in a plan view. Each of the first and second dish support portions is configured to be able to support a plurality of bottomed cylindrical dishes typified by cups and tea cups in an inclined posture with the open end facing downward and away from the center of curvature of the arc shape in the longitudinal direction of each dish support portion. As a result, the washing water jetted from the nozzle holes formed in the center nozzle easily enters the cylindrical dishes supported by each dish support portion, and even if the open ends of the adjacent cylindrical dishes are supported so as to be in contact with each other, a gap is formed between the peripheral wall portions of the adjacent cylindrical dishes, and the outer surfaces of the peripheral wall portions of each cylindrical dish can be well washed.

[0003] Incidentally, it is desirable to be able to place a cutting board in an upright position in the lower basket so that it can be washed. However, in the conventional example described above, the Y-axis ends of the first and second dish support parts extend to the supported frame parts in the Y-axis direction. As a result, when a cutting board is placed in an upright position in the lower basket, the top of the cutting board interferes with the dish support parts of the upper basket, making it impossible to set the upper basket in the washing tank. [Prior art documents] [Patent Documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2016-30163 [Overview of the project] [Problems that the invention aims to solve]

[0005] In view of the above, the object of the present invention is to provide a dishwasher that allows the upper basket to be set in the washing tank with the cutting board placed in an upright position in the lower basket. [Means for solving the problem]

[0006] To solve the above problems, the present invention provides a dishwasher comprising a washing tank containing a dish basket for supporting tableware, a washing nozzle provided in the washing tank, and a washing pump for supplying washing water from the washing tank to the washing nozzle, wherein the washing nozzle has a center nozzle extending upward in the center of the washing tank, and the dish basket is provided as a lower basket located at the bottom of the washing tank and an upper basket located at the top of the washing tank, in a plan view away from the center nozzle, and the upper basket is positioned with one of the depth direction and width direction of the washing tank in the X-axis direction and the other in the X-axis direction In the Y-axis direction, the washing tank has two supported frame portions in the Y-axis direction, supported by support portions provided on the inner surfaces of the side walls of one and the other side of the washing tank in the Y-axis direction, and a first dish support portion that extends in an arc shape between the two supported frame portions, with the center in the Y-axis direction being opposite to the center nozzle in the X-axis direction when viewed from above. The first dish support portion can support multiple cylindrical dishes with bottoms, such as cups and teacups, arranged in a slanted position with the open end facing downwards and tilted away from the center of curvature of the arc, along the longitudinal direction of the first dish support portion. It has a seat portion on which the open end of the cylindrical tableware rests, and a backrest portion on which the peripheral wall of the cylindrical tableware abuts. In this invention, one side end of the first dish support portion in the Y-axis direction extends to the supported frame portion in the Y-axis direction, the other side end of the first dish support portion in the Y-axis direction extends to a side frame portion located at a predetermined distance in the Y-axis direction from the supported frame portion in the other Y-axis direction, and a plurality of connecting frames spaced apart in the X-axis direction are provided to connect this side frame portion and the supported frame portion in the other Y-axis direction, and each connecting frame is formed in a gate shape having a pair of vertical frame portions that rise upward from the side frame portion and the supported frame portion in the other Y-axis direction, and a connecting portion that connects both vertical frame portions at their upper ends, and the installation position of each connecting frame is set to a position that does not interfere with a part of the peripheral wall portion of a cylindrical dish of a predetermined diameter supported in the inclined position at the part closest to the other side end of the first dish support portion in the Y-axis direction extending beyond the side frame portion in the Y-axis direction.

[0007] According to the present invention, by placing a cutting board in an upright position on the lower basket portion located directly below the gap between the supported frame portion and the side frame portion on the other side in the Y-axis direction of the upper basket, the upper part of the cutting board is inserted into the gap between the supported frame portion and the side frame portion on the other side in the Y-axis direction, and because each connecting frame is gate-shaped, there is no interference of the cutting board with each connecting frame. Therefore, the upper basket can be set in the washing tank with the cutting board placed in an upright position on the lower basket. Furthermore, by setting the installation position of each connecting frame as described above, if a cutting board is not placed on the lower basket, a cylindrical dish of a predetermined diameter can be supported in the inclined position at the nearest part to the other side end in the Y-axis direction of the first dish support portion without interference with each connecting frame. Therefore, the number of cylindrical dishes that can be supported by the first dish support portion is not reduced by providing connecting frames.

[0008] Furthermore, in the present invention, the upper basket has a second dish support portion adjacent to the first dish support portion in one direction along the X-axis, and extending in an arc shape that curves along the first dish support portion in a plan view, and the second dish support portion can support multiple cylindrical dishes arranged in the longitudinal direction of the second dish support portion in an inclined position with the open end facing downwards and inclined away from the center of curvature of the arc shape. It has a seat portion on which the open end of the cylindrical tableware rests, and a backrest portion on which the peripheral wall of the cylindrical tableware abuts. In this case, it is desirable that one side end of the second dish support in the Y-axis direction extends to the supported frame in the Y-axis direction, the other side end of the second dish support in the Y-axis direction extends to the side frame, and the installation position of each connecting frame is set to a position that does not interfere with a part of the peripheral wall of a cylindrical dish of a predetermined diameter, which is supported in the inclined position by the part closest to the other side end of the second dish support in the Y-axis direction, extending beyond the side frame in the other direction. More specifically, when two connecting frames, a first and a second, are provided as connecting frames, the installation position of the first connecting frame located in the other direction in the X-axis direction should be set such that one end of the vertical frame portion of the first connecting frame rising from the side frame portion is located in the middle of the seat portion in the X-axis direction at the other side end in the Y-axis direction of the first dish support portion, or at a position shifted in the other direction in the X-axis direction from there. The installation position of the second connecting frame located in the one direction in the X-axis direction should be set such that one end of the vertical frame portion of the second connecting frame rising from the side frame portion is located in the X-axis direction and the middle of the seat portion in the X-axis direction at the other side end in the Y-axis direction of the second dish support portion are at the same position in the X-axis direction.

[0009] According to this, even when a second dish support is provided in addition to the first dish support in the upper basket, the upper basket can be set in the washing tank with the cutting board placed in an upright position in the lower basket, and furthermore, the number of cylindrical dishes that can be supported by the second dish support does not decrease by providing a connecting frame.

[Figure 7] A cross-sectional plan view obtained by cutting along the line VII-VII in Figure 6. [Modes for carrying out the invention]

[0011] The dishwasher according to the embodiment of the present invention shown in Figure 1 is a built-in type that is installed in a system kitchen and is equipped with a washing tank 2 that can be freely pulled out from the front inside a main body 1 with an open front. A dish basket, which will be described later, is stored inside the washing tank 2 and a washing nozzle 3 is provided for spraying washing water towards the dish basket. A front cover 21 is attached to the front of the washing tank 2 to close the front of the main body 1. In addition, a seal cover 11 is provided at the top inside the main body 1 to close the open top surface of the washing tank 2.

[0012] A reservoir 23 for cleaning water is provided at the bottom of the cleaning tank 2, which communicates with the inside of the cleaning tank 2 via a food residue filter 22. A cleaning pump 4 is installed on the underside of the bottom of the cleaning tank 2, which communicates with the reservoir 23. When the cleaning pump 4 is rotated forward, the cleaning water in the cleaning tank 2 is supplied to the cleaning nozzle 3 via the reservoir 23 and the cleaning pump 4, and when the cleaning pump 4 is rotated in reverse, the cleaning water is drained from the cleaning tank 2.

[0013] The cleaning nozzle 3 has a lower nozzle 31 that extends horizontally at the bottom of the cleaning tank 2 and is rotatable around a vertical axis at its longitudinal center, and a center nozzle 32 that is erected at the longitudinal center of the lower nozzle 31 and extends upward at the center of the cleaning tank 2. The lower nozzle 31 sprays cleaning water from a nozzle hole 31a formed therein and rotates due to the reaction force of this spray. The center nozzle 32 sprays cleaning water from a nozzle hole 32a formed at its upper part.

[0014] Furthermore, the dish rack is provided as follows: a lower basket 5 located at the bottom of the washing tank 2, positioned above the lower nozzle 31, to support relatively large dishes W1 such as large plates, small plates, medium bowls, and soup bowls; and an upper basket 6 located at the top of the washing tank 2, away from the center nozzle 32 in a plan view. A nozzle guard frame 51 is erected in the center of the lower basket 5 to prevent the dishes W1 placed on it from interfering with the center nozzle 32.

[0015] The upper basket 6 will be described below, with the depth direction (front-to-back direction) of the washing tank 2 defined as the X-axis direction and the width direction (side-to-side direction) defined as the Y-axis direction. See also Figures 2 to 4, the upper basket 6 has a first supported frame portion 61 in the Y-axis direction that is supported across two support portions 24, 25 (see Figure 5(a)) provided on the inner surface of one side wall portion of the washing tank 2 in the Y-axis direction and spaced apart in the X-axis direction, and a second supported frame portion 62 in the other Y-axis direction that is supported across two support portions 26, 27 (see Figure 5(b)) provided on the inner surface of the other side wall portion of the washing tank 2 in the Y-axis direction and spaced apart in the X-axis direction, and a first dish support portion 63 that extends in an arc shape between the first and second support frame portions 61, 62, with the center portion in the Y-axis direction being in the opposite direction from the center nozzle 32 in one X-axis direction in a plan view, and a second dish support portion 64 that is adjacent to one X-axis side of the first dish support portion 63 and extends in an arc shape along the first dish support portion 63 in a plan view. The first supported frame portion 61 is supported by a support portion 25 provided near the end in the X-axis direction of the inner surface of one side wall portion in the Y-axis direction of the washing tank 2, via a pin 61a (see Figure 7) protruding from the end in the X-axis direction of the first supported frame portion 61.

[0016] Each of the first and second tableware support portions 63 and 64 is configured to be able to support a plurality of bottomed cylindrical tablewares W2 typified by cups and teacups in an inclined posture with the open end facing downward and inclined in a direction away from the center of curvature of the arc shape in the longitudinal direction of each of the tableware support portions 63 and 64. According to this, the washing water jetted from the nozzle holes 32a formed in the center nozzle 32 easily enters the cylindrical tableware W2 supported by each of the tableware support portions 63 and 64. Also, even if the cylindrical tablewares W2 and W2 adjacent to each other are supported such that their open ends are in contact with each other, a fan-shaped gap that becomes wider as it moves away from the open end is formed between the peripheral wall portions of the adjacent cylindrical tablewares W2 and W2, and the outer surface of the peripheral wall portion of each cylindrical tableware W2 can be washed well. Incidentally, each of the tableware support portions 63 and 64 has a seat portion 63a and 64a on which the open end of the cylindrical tableware W2 sits, and a backrest portion 63b and 64b against which the peripheral wall portion of the cylindrical tableware W2 abuts.

[0017] The upper basket 6 further has a side frame portion 65 provided at a position a predetermined distance away in one direction in the Y-axis direction from the second supported frame portion 62 on the other side in the Y-axis direction, and two first and second connecting frames 661 and 662 spaced apart in the X-axis direction that connect the side frame portion 65 and the second supported frame portion 62. And one side end in the Y-axis direction of each of the first and second tableware support portions 63 and 64 extends to the first supported frame portion 61, and the other side end in the Y-axis direction of each of the tableware support portions 63 and 64 extends not to the second supported frame portion 62 but to the side frame portion 65. Also, each of the first and second connecting frames 661 and 662 is formed in a gate shape having a pair of vertical frame portions 66a and 66b rising upward from the side frame portion 65 and the second supported frame portion 及び62, and a connecting portion 66c connecting the upper ends of both vertical frame portions 66a and 66b. Incidentally, a reinforcing frame 65a is connected to one end (rear end) in the X-axis direction of the side frame portion 65, and this reinforcing frame 65a is supported by a support portion 28 (see FIG. 5b) provided on the inner surface of one side wall portion (rear wall portion) in the X-axis direction of the washing tub 2 via a pin 65b protruding therefrom.

[0018] Here, referring also to FIGS. 6 and 7, the installation positions of the first and second connecting frames 661 and 662 are such that a part of the peripheral wall of a cylindrical tableware W2 with a predetermined diameter supported in the above-described inclined posture (the posture inclined in the direction away from the center of curvature of the arc shape) at the nearest part of the other side end in the Y-axis direction of the first and second tableware support parts 63 and 64 does not interfere with the protrusion of the other side in the Y-axis direction from the side frame part 65. Here, since the diameter (outer diameter) of a general cylindrical tableware W2 is at most about 7 cm, the above-described predetermined diameter is set to 6 cm, which is about the same. FIGS. 6 and 7 show a cylindrical tableware W2 with a predetermined diameter. Note that the nearest part of the other side end in the Y-axis direction of each of the tableware support parts 63 and 64 refers to the part where the open end of the cylindrical tableware W2 substantially contacts the side frame part 65.

[0019] In the present embodiment, the installation position of the first connecting frame 661 located on the other side (front side) in the X-axis direction is set such that the end on the other side in the X-axis direction of the seat part 63a at the other side end in the Y-axis direction of the first tableware support part 63 and the end on the one side in the X-axis direction of the vertical frame part 66a of the first connecting frame 661 are at the same position in the X-axis direction. However, even if the end on the one side in the X-axis direction of the vertical frame part 66a of the first connecting frame 661 is at the intermediate part in the X-axis direction of the seat part 63a at the other side end in the Y-axis direction of the first tableware support part 63 (the position indicated by A in FIG. 7), the above conditions can be satisfied. Further, in the present embodiment, the installation position of the second connecting frame 662 located on the one side (rear side) in the X-axis direction is set such that the intermediate part in the X-axis direction of the seat part 64a at the other side end in the Y-axis direction of the second tableware support part 64 and the end on the one side in the X-axis direction of the vertical frame part 66a of the second connecting frame 662 are at the same position in the X-axis direction. Note that the vertical frame part 66a of the first connecting frame 661 is integrated with the reinforcing frame 66d and has a U-shaped cross section.

[0020] With the above configuration, by placing the cutting board W3 (see Figures 2 and 3) in an upright position on the lower basket 5, which is located directly below the gap between the second supported frame portion 62 and the side frame portion 65 on the other side of the upper basket 6 in the Y-axis direction, the upper part of the cutting board W3 is inserted into the gap between the second supported frame portion 62 and the side frame portion 65. Furthermore, because the first and second connecting frames 661 and 662 are gate-shaped, there is no interference between the cutting board W3 and the connecting frames 661 and 662. Therefore, the upper basket 6 can be set in the washing tank 2 with the cutting board W3 placed in an upright position on the lower basket 5. Furthermore, by setting the installation positions of each connecting frame 661, 662 as described above, if a cutting board W3 is not placed on the lower basket 5, a cylindrical dish W2 of a predetermined diameter can be supported in the inclined position at the nearest part of the other side end of the first and second dish support parts 63, 64 in the Y-axis direction without interference with each connecting frame 661, 662. Therefore, the number of cylindrical dishes W2 that can be supported by each dish support part 63, 64 is not reduced by providing the connecting frames 661, 662.

[0021] Although embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited thereto. For example, in the above embodiment, the depth direction of the washing tank 2 is the X-axis direction and the width direction is the Y-axis direction, but it is also possible to make the width direction of the washing tank 2 the X-axis direction and the depth direction the Y-axis direction, that is, the upper basket 6 may have a support frame portion on one side and the other side wall portion of the washing tank 2 that is supported by support portions provided on the inner surface of the side wall portion on one side and the other side in the depth direction of the washing tank 2, a first and second dish support portion that extends in an arc shape between the two support frame portions, with the center portion in the depth direction being in the opposite direction to the center nozzle 32 in a plan view, a side frame portion that is a predetermined distance in the depth direction from the support frame portion on the other side in the depth direction, and a connecting frame that connects the side frame portion and the support frame portion on the other side in the depth direction.

[0022] Furthermore, although the above embodiment provides two connecting frames 661 and 662, the number of connecting frames may be three or more, as long as the above conditions for installation location are met. In addition, the second dish support part 64 provided on the upper basket 6 can be omitted. Moreover, although the dishwasher in the above embodiment is a built-in type, the present invention can also be similarly applied to a tabletop dishwasher with an open front surface and a front door that opens and closes this front surface.
