[Modes for carrying out the invention]

[0008] <Embodiment> 1. Overall This explanation will primarily utilize Figure 1. Dishwasher X is a so-called front-opening type, where the door 113 is tilted (opened) and the baskets 21 and 23 inside the washing chamber 11 are pulled out for use. Although not shown in the diagram, dishwasher X is built into the kitchen counter. In this embodiment, with the dishwasher in the washing operation state (state shown in Figure 1(a)), the side facing the user to the washing chamber is defined as the front, the direction perpendicular to the front is defined as the front-rear direction, and the direction perpendicular to the front-rear direction in the horizontal direction is defined as the left-right direction. "Right" or "left" is based on the user's perspective when facing the front. Alternatively, the front may be defined as the side facing the user who operates the control panel 83 of the dishwasher X. Furthermore, if the dishwasher X is equipped with a door 113, the side on which the closed door 113 is located becomes the front, and the direction perpendicular to the closed door 113 becomes the front-to-back direction. Dishwasher X is, for example, a "slim-width type" dishwasher with a width of 30 cm. The door 113 can be opened and closed using the handle 114 at the top of the door 113. When the door 113 is open, the dishwasher X houses baskets 21 and 23 that can be moved in and out of the washing chamber 11 (washing chamber body 111). Here, the baskets 21 and 23 are housed in two tiers, upper and lower. The upper basket 21 can hold cups, small plates, etc., while the lower basket 23 can hold large plates, small plates, bowls, etc. Furthermore, the back surface of the door body 113 also functions as a support part that supports the lower basket 23 pulled out from the washing chamber body 111 from below, and has a guide part 113a for the wheels 236 of the lower basket 23 on its back surface.

[0009] As shown in Fig. 2, the dishwashing machine X includes a washing chamber 11 for accommodating an object to be washed, an upper chamber 13 provided above the washing chamber 11, and a lower chamber 15 provided below the washing chamber 11. The dishwashing machine X includes a washing unit 51 for washing an object to be washed in the washing chamber 11. The dishwashing machine X includes a functional unit related to the washing of an object to be washed in the lower chamber 15. The functional unit will be described later. In addition, the front opening 105g of the lower chamber 15 is covered by the front cover 106 shown in Fig. 1. The front cover 106 includes a front upper cover 107 and a front lower cover 108, and each is detachably attached to the lower cover 105 (see Fig. 4). The following will be described in detail.

[0010] 2. Washing Chamber As shown in Fig. 2, the washing chamber 11 has a long box shape in the vertical direction. The washing chamber 11 includes a washing chamber main body 111 having an opening on the front side, and a door body 113 for opening and closing the opening of the washing chamber main body 111, and a space for accommodating an object to be washed is formed inside. As shown in Figs. 2 and 3, the washing chamber main body 111 is composed of two upper and lower members, and includes a main body lower member 111A and a main body upper member 111B.

[0011] As shown in Fig. 3, the main body lower member 111A and the main body upper member 111B are fixed to each other by fixing tools such as screws, for example, and the front sides of the main body lower member 111A and the main body upper member 111B are fixed to a pair of frame members 17 extending vertically and arranged horizontally. The door body 113 is supported by the hinge shaft 171 of the frame member 17 on its lower side, so that the opening of the washing chamber main body 111 can be opened and closed.

[0012] 3. Support Portion As shown in Fig. 1(b), the upper support portion 31 and the lower support portion 32 support the baskets 21 and 23. The upper support section 31 supports the upper basket 21. The upper support section 31 comprises a movable support 312 that detachably supports the upper basket 21 and extends in the front-rear direction, a fixed support 313 disposed on the inner surface of the side wall 111Bb of the washing chamber body 111 and supporting the movable support 312 so as to be slidable in the front-rear direction, and a fixing body 315 (see Figure 3) disposed on the outer surface of the side wall 111Bb of the washing chamber body 111 and for fixing the fixed support 313. The lower support section 32 is composed of a stepped portion 321. The stepped portion 321 is provided on the lower main body member 111A, and the step is lower on the inner side in the left-right direction and extends in the front-rear direction. The lower basket 23 is provided with wheels 236 for movement (see Figure 1(b)), and the wheels 236 move in the front-rear direction on the flat area of ​​the stepped portion 321.

[0013] 4.Water supply part As shown in Figure 3, the water supply unit 41 includes a water supply valve 42 for starting and stopping the water supply, a water supply pipe 43 connecting the water supply valve 42 to a water source (not shown), and a water supply nozzle 44 (see Figure 2) that communicates with the water supply valve 42 and discharges water into the washing chamber 11. The water supply unit 41 is located to the left of the center in the left-right direction. The water supply valve 42 is provided on the outer surface of the rear wall 111Bc of the washing chamber 11 (upper main body member 111B), and the water supply nozzle 44 is provided on the inner surface of the rear wall 111Bc of the washing chamber 11 (upper main body member 111B) (see Figure 2).

[0014] 5. Water collection area As shown in Figure 5, the water collection section 71 is composed of a projection 111Ad that protrudes downward from the bottom wall 111Aa. More specifically, the water collection section 71 protrudes downward in a bottomed cylindrical shape from the bottom portion 111Ai of the recess 111Ah provided in the bottom wall 111Aa.

[0015] As shown in Figure 6, the water collection section 71 has a rear cylindrical portion 111Ae that extends rearward from the peripheral wall 111Aj near the bottom wall 111Ak, and the cleaning pump 54 is connected to this rear cylindrical portion 111Ae. Therefore, the rear cylindrical portion 111Ae functions as a connection point to the cleaning pump 54. The downstream end of the rear cylindrical portion 111Ae constitutes an inlet 541 for supplying water or cleaning water to the cleaning pump 54. The water collection section 71 has a front cylindrical portion 111An that protrudes further downward from the bottom wall 111Ak of ​​the protruding portion 111Ad and extends forward from its peripheral wall 111Am, and a drain pump 62 is connected to this front cylindrical portion 111An. The front cylindrical portion 111An constitutes an outlet for discharging cleaning water to the drain pump 62, and the downstream end of the front cylindrical portion 111An constitutes an outlet 62a. Filters are provided in the water collection section 71 and the recess 111Ah. This makes it difficult for food residue to enter the water collection section 71. Specifically, a plate-shaped filter 72 is fitted into the recess 111Ah, and a cylindrical filter 73 is provided extending upward from the through-hole of the filter 72.

[0016] 6. Cleaning section As shown in Figure 2, the cleaning unit 51 includes an upper nozzle body 52 for discharging cleaning water toward an object to be cleaned placed on the upper basket 21 (see Figure 1(b)), a lower nozzle body 53 for discharging cleaning water toward an object to be cleaned placed on the lower basket 23, a cleaning pump 54, a water splitter 55 for splitting the cleaning water from the cleaning pump 54 to the upper nozzle body 52 side and the lower nozzle body 53 side, an upper communication channel 56 connecting the water splitter 55 and the upper nozzle body 52, and a lower communication channel 57 connecting the water splitter 55 and the lower nozzle body 53. Note that the water splitter 55 corresponds to an example of the "water splitter" of Invention 1.

[0017] (1) Nozzle body As shown in Figure 2, there are two upper nozzle bodies 52 spaced apart in the front-to-back direction. Each upper nozzle body 52 has multiple discharge nozzles 521 in the left-to-right direction. There are two lower nozzle bodies 53, spaced apart in the front-to-back direction. The lower nozzle body 53 located on one side (in this case, the front side) has multiple discharge nozzles 531 in the front-to-back direction. The lower nozzle body 53 located on the other side (in this case, the rear side) has multiple discharge nozzles 531 in the left-to-right direction.

[0018] (2) Washing pump As shown in Figure 5, the cleaning pump 54 is installed on the bottom wall 111Aa of the lower main body member 111A and is housed in the lower chamber 15 (see Figure 2). The cleaning pump 54 is located behind the water collection section 71. This allows for a reduction in the vertical dimension. The cleaning pump 54 is connected to the rear cylindrical portion 111Ae of the water collection section 71 and sends cleaning water from the water collection section 71 to the water distributor 55 (see Figure 2). The cleaning pump 54, for example, has a rotating shaft C1 that is horizontal and extends parallel to the front-rear direction, or extends so as to intersect the front-rear direction at an angle within the range of -10 to 10°. The cleaning pump 54 has an inlet 541 for connecting to the water collection section 71. The inlet 541 faces in the front-to-back direction (in this case, the front). The cleaning pump 54 used here is a type that has an integrated heater for heating the cleaning water.

[0019] (3) Upper connecting channel As shown in Figure 2, the upper communication channel 56 has an upper first channel 562, an upper second channel 563, and an upper third channel 564. The upper second channel 563 communicates with the upper first channel 562. The upper second channel 563 is formed inside the rear cylindrical body 566, which is located on the inner surfaces of the rear walls 111Ac (see Figure 3) and 111Bc and extends in the vertical direction. As shown in Figure 3, the rear wall 111Bc of the main body upper member 111B has an overhang 111Bd that protrudes to the rear in order to accommodate the rear cylindrical body 566 (see Figure 2). Returning to Figure 2, the rear cylinder 566 and the protruding portion 111Bd are provided to extend vertically from the center or periphery in the left-right direction. The upper third channel 564 communicates with the upper second channel 563 and the channel within the upper nozzle body 52. ​​The upper third channel 564 is formed inside the upper cylindrical body 567, which extends forward from the upper end of the rear cylindrical body 566.

[0020] As shown in Figure 7, the upper first channel 562 has an upper inlet 561 that receives washing water from the water distributor 55. The upper first channel 562 is formed between a groove portion 111Af formed in the bottom wall 111Aa of the washing chamber body 111 and a cover plate 115 (see Figure 2) that covers the groove portion 111Af, and extends from the upper inlet 561 to the rear wall 111Ac (see Figure 2).

[0021] (4) Lower connecting channel As shown in Figure 2, the lower communication channel 57 has a lower first channel 572 having a lower inlet 571 for receiving washing water from the water distributor 55, and a lower second channel 573 that communicates with the lower first channel 572 and the channel inside the lower nozzle body 53.

[0022] As shown in Figure 7, the lower first channel 572 is formed between a groove portion 111Ag formed in the bottom wall 111Aa of the washing chamber body 111 and a cover plate 115 (see Figure 5(a)) that covers the groove portion 111Ag. The lower first channel 572 extends in the front-rear direction. The lower second channel 573 is formed inside the cylindrical portion 115a of the cover plate 115, as shown in Figure 5(a).

[0023] (5) Water divider As shown in Figure 2, the water distributor 55 has the function of distributing the cleaning water sent from the cleaning pump 54 to supply the upper nozzle body 52 and the lower nozzle body 53. As shown in Figure 7, the water divider 55 comprises a case section 551 having an inlet 551a into which cleaning water flows from the cleaning pump 54, a communication passage 552 that communicates with the inlet 551a and also with the upper receiving inlet 561 of the upper communication passage 56 and the lower receiving inlet 571 of the lower communication passage 57, a water divider plate 553 that can be rotated to select between an upper communication state and a lower communication state, and a driving means 554 that rotates the water divider plate 553. The upper connection state is when the connecting passage 552 and the upper receiving port 561 are in communication, and the lower connection state is when the connecting passage 552 and the lower receiving port 571 are in communication. In the bottom wall 111Aa, an upper receiving port 561 and a lower receiving port 571 are formed in the portion facing the inside of the cylindrical portion that constitutes the case portion 551, and the inside of the case portion (cylindrical portion) 551 is configured to communicate with an upper communication channel 56 and a lower communication channel 57.

[0024] As shown in Figure 8, the case portion 551 is composed of a cylindrical portion that protrudes downward from the bottom wall 111Aa of the lower main body member 111A (see Figure 2). The connecting passage 552 is formed by the peripheral wall 556a and bottom wall 556b of the bottomed cylindrical portion 556 inserted into the case portion 551. The peripheral wall 556a has a notched portion 556c in the part corresponding to the inlet 551a, and the bottom wall 556b is configured to become higher upward as it moves away from the notched portion 556c in the circumferential direction. In other words, the connecting passage 552 is spiral-shaped. The water distribution plate 553 has a plate portion 553a and an arc-shaped through-hole portion 553b. When the upper inlet 561 is blocked by the plate portion 553a, the lower inlet 571 faces the through-hole portion 553b (the lower inlet is in communication), and when the lower inlet 571 is blocked by the plate portion 553a, the upper inlet 561 faces the through-hole portion 553b (the upper inlet is in communication). By rotating with the driving means 554, the communication between the upper communication channel 56 and the lower communication channel 57 alternates.

[0025] 7. Drainage section As shown in Figures 4 and 10, the drainage section 61 includes a drainage pump 62 connected to the water collection section 71, a trap 64 connected to the discharge side of the drainage pump 62 via a hose 63, and a drainage pipe 65 connected to the trap 64. As shown in Figure 10, the drain pump 62 is connected to the front cylindrical portion 111An of the water collection section 71 and is configured to send the cleaning water from the water collection section 71 to the trap 64. The drain pump 62 has an outlet 62a (front cylinder portion 111An) that connects to the water collection section 71 facing in the front-to-back direction (towards the rear in this case), and an outlet 62b that connects via a hose 63 facing to the other side in the left-to-right direction (towards the right in this case). This allows the hose 63 to be easily positioned. The trap 64 is located to the right of the cleaning pump 54. The trap 64 is a flattened box shape with a small left-right dimension and is positioned approximately perpendicular to the left-right direction. This allows for a smaller left-right dimension. Although not shown in the diagram, trap 64 can be, for example, an S-shaped trap, to prevent the entry of pests and the generation of foul odors.

[0026] As shown in Figure 5, the drainage section 61 is provided on the bottom wall 111Aa of the lower main body member 111A and is housed in the lower chamber 15 (see Figure 2). The drain pump 62 has a rotating shaft C2 that is horizontal and extends parallel to the front-rear direction, or extends so as to intersect the front-rear direction at an angle within the range of -10 to 10°. The rotating shaft C2 of the drain pump 62 and the rotating shaft C1 of the cleaning pump 54 are parallel or intersect at an angle within the range of -10 to 10°. This allows for a reduction in the dimensions in the left-right direction.

[0027] 8. Upper Room As shown in Figure 2, the upper chamber 13 is formed between the top wall 111Ba of the washing chamber body 111 and the upper cover plate 104, and is covered in the left-right direction by the right cover plate 101 (see Figure 1) and the left cover plate. As shown in Figure 3, the upper chamber 13 houses the hot air blowing unit 81, the exhaust unit 82, the operating unit 83, the circuit unit 84, and the like.

[0028] 9. Hot air blower As shown in Figure 3, the hot air blowing unit 81 includes a blowing means 811 for blowing out air, a heating means 812 for heating the blown-out air, and a duct 813 connecting the heating means 812 to the outlet 11a of the washing chamber 11 (see Figure 5(a)). The duct 813 forms an air passage inside and is provided on the outer surface of the rear wall 111Bc of the upper main body member 111B and the inner surface of the rear wall 111Ac of the lower main body member 111A (see Figure 5(a)). As shown in Figure 4(a), the outlet 11a of the washing chamber 11 is formed on the lower right side of the washing chamber 11. Therefore, the duct 813 is located to the right of the center in the left-right direction.

[0029] 10. Exhaust section As shown in Figure 3, the exhaust unit 82 has an exhaust duct 822 with an exhaust port 821 (see Figure 2) that communicates with the outside. The exhaust is carried out using the blowing means 811 of the hot air blowing unit 81, which is connected to the blowing means 811 via a hose 823. The exhaust duct 822 communicates with the through hole 11b (see Figure 4(a)) of the washing chamber 11.

[0030] 11.Circuit section As shown in Figure 2, the circuit section 84 has electronic components (not shown) and a circuit board 841, is placed on a support section 111Be (see Figure 4(a)) formed on the top wall 111Ba of the cleaning chamber body 111, and is covered by a cover plate 842 (see Figure 3).

[0031] 12.Lower chamber The lower chamber 15 (see Figure 2) houses the drainage section 61, the washing pump 54 and water distributor 55, the water collection section 71, etc., as shown in Figures 4 and 9. As shown in Figure 4, the lower chamber 15 consists of the bottom wall 111Aa of the washing chamber body 111, a lower cover 105 positioned at a distance below the bottom wall 111Aa, a front cover 106 (see Figure 1) that covers the bottom wall 111Aa and the lower cover 105 from the front, and a right cover plate 101 (see Figure 1) and a left cover plate. The lower cover 105 has a bottom wall 105a, a rear wall 105b erected from the rear end of the bottom wall 105a, side walls 105c erected from the left and right ends of the bottom wall 105a, a front wall 105d erected from the front end of the bottom wall 105a, a rear extension 105e extending rearward from the upper end of the rear wall 105b, and a plurality of support parts 105f for supporting the washing chamber body 111. The front wall 105d is lower than the rear wall 105b, forming an opening 105g (see Figure 2) between it and the washing chamber body 111. This allows for easy maintenance of the drain pump 62 located at the front (e.g., replacement) and maintenance of the piping such as the water supply pipe 43 and drain pipe 65 (e.g., pipe blockage, water leaks). The opening 105g is closed by a front cover 106 (see Figure 1) that is detachable from the lower cover 105. There are a total of four support parts 105f, one in the front, one in the back, one in the left, and one in the right, and they support (connect) the supported part 111Ap of the washing chamber body 111 (body lower member 111A). Therefore, the lower cover 105 has a base function. The support parts 105f are fitted onto the supported part 111Ap from below and fastened with screws. An opening 105h is formed in the rear wall 105b, through which the water supply pipe 43 and drainage pipe 65 are routed.

[0032] <Placement> Figure 10 illustrates the view of the lower chamber 15 from below. The water collection section 71 is located in the center in the front-to-back direction (including its periphery) and on either the left-to-right side of the center (in this case, the right side). The drain section 61 is located in front of the water collection section 71 in the front-to-back direction. The drain pump 62 has an outlet 62a (see Figure 6) (front cylindrical section 111An) that connects to the water collection section 71 facing the rear, and an outlet 62b that connects via a hose 63 facing the other side in the left-to-right direction (in this case, the right side). The cleaning pump 54 is located behind the water collection unit 71 in the front-to-back direction. The cleaning pump 54 has an inlet 541 that connects to the water collection unit 71 facing in the front-to-back direction (in this case, the front), and an outlet 542 that connects to the water splitter 55 and hose 59 (see Figure 7) facing to one side in the left-to-right direction (in this case, the left).

[0033] The arrangement of the functional components and water distributor (water distribution section) within the lower chamber 15 will be explained using Figure 11. The functional components specifically include a cleaning pump 54 (cleaning pump unit) that has the function of supplying cleaning water to the cleaning chamber 11, a drainage pump 62 (drainage pump unit) that has the function of discharging cleaning water from the outlet 62a, and a water collection unit 71 that has the function of collecting water and cleaning water from inside the cleaning chamber 11. Here, the term "washing pump section" encompasses both cases: a washing pump alone, and a washing pump with a case housing the washing pump. Similarly, the term "drainage pump section" also encompasses both cases: a drainage pump alone, and a drainage pump with a case housing the drainage pump.

[0034] 1. Regarding the cleaning pump 54, water collection unit 71, and drainage pump 62 (1) The cleaning pump 54, the water collection unit 71, and the drainage pump 62 are arranged in the front-to-back direction. Here, they are arranged in the order of drainage pump 62, water collection unit 71, and cleaning pump 54 from the front. Note that the arrangement is not limited to this order; it may be in the order of cleaning pump 54, water collection unit 71, and drainage pump 62 from the front, or in the order of water collection unit 71, cleaning pump 54, and drainage pump 62, or in the order of water collection unit 71, drainage pump 62, and cleaning pump 54. This allows the cleaning pump 54, the water collection unit 71, and the drainage pump 62 to be arranged compactly in the left-right direction.

[0035] (2) Of the left-right dimension L1 of the cleaning pump 54, the left-right dimension L2 of the water collection section 71, and the left-right dimension L3 of the drainage pump 62, the largest dimension is the dimension L1 of the cleaning pump 54. Part or all of the water collection section 71 and the drainage pump 62 overlap with the cleaning pump 54 in the front-rear direction. In other words, when viewed from the front-rear direction, part or all of the water collection section 71 and the drainage pump 62 overlap with the cleaning pump 54. In other words, when viewed from above, the water collection section 71 and part or all of the drainage pump 62 are located in the region between a virtual line L11 that passes through the right end of the cleaning pump 54 and extends in the front-to-back direction, and a virtual line L12 that passes through the left end of the cleaning pump 54 and extends in the front-to-back direction. This is where a portion of the water collection section 71 and the entirety of the drainage pump 62 are located. This allows the cleaning pump 54, the water collection unit 71, and the drainage pump 62 to be arranged compactly in the left-right direction.

[0036] (3) When viewed in the vertical direction, the imaginary line L13, which is an extension of the rotation axis of the cleaning pump 54, and the imaginary line L31, which is an extension of the rotation axis of the drainage pump 62, pass through the water collection section 71. In other words, the water collection section 71 is located on the imaginary lines L13 and L31. This allows the cleaning pump 54, the water collection unit 71, and the drainage pump 62 to be arranged compactly in the left-right direction.

[0037] (4) The left-right dimension L1 of the cleaning pump 54 is within the range of 0.9 to 1.3 times the left-right dimension L2 of the water collection section 71. The left-right dimension L3 of the drainage pump 62 is within the range of 0.4 to 1.5 times the left-right dimension L2 of the water collection section 71. This allows the cleaning pump 54, the water collection unit 71, and the drainage pump 62 to be arranged compactly in the left-right direction.

[0038] (5) The water collection section 71 is located between the cleaning pump 54 and the drainage pump 62 in the front-to-back direction. In this case, when viewed from the left-to-right direction, the water collection section 71 may or may not overlap with the cleaning pump 54 or the drainage pump 62. If they overlap, the unit can be made more compact in the front-to-back direction. This makes it easy to connect the cleaning pump 54 to the water collection unit 71, and to connect the drainage pump 62 to the water collection unit 71.

[0039] (6) At least part or all of the water supply pipe 43 for supplying cleaning water and the drain pipe 65 for discharging cleaning water are arranged in the left-right direction with respect to the cleaning pump 54, water collection section 71, and drain pump 62. If the imaginary line L13 passing through the rotation axis of the cleaning pump 54, which has the largest dimension in the left-right direction, is located on the other side (for example, the right side) relative to the center in the left-right direction, then at least part or all of one of the water supply pipe 43 and the drain pipe 65 is positioned on one side (the left side) in the left-right direction relative to the cleaning pump 54, the water collection unit 71, and the drain pump 62. This allows for a more compact lateral dimension of the device. Furthermore, it enables effective use of the lateral space in the area where the cleaning pump 54, water collection unit 71, and drainage pump 62 are located.

[0040] 2. Regarding the washing pump 54, water collection unit 71, drainage pump 62, and water splitter 55 (1) The cleaning pump 54, water collection unit 71, drainage pump 62, and water splitter 55 are arranged in the front-to-back direction. Here, from the front, they are arranged in the order of drainage pump 62, water collection unit 71 and water splitter 55, and cleaning pump 54. Note that the arrangement is not limited to this order. From the front, the order may be: cleaning pump 54, water collection unit 71 and water splitter 55, drainage pump 62; water collection unit 71 and water splitter 55, cleaning pump 54, drainage pump 62; water collection unit 71 and water splitter 55, drainage pump 62, cleaning pump 54; drainage pump 62, water collection unit 71, cleaning pump 54, water splitter 55; or water splitter 55, cleaning pump 54, water collection unit 71, drainage pump 62. Furthermore, the water collection section 71 and the water distributor 55 only need to be close to each other in the front-to-back direction, and the water collection section 71 may be on the front side, or the water distributor 55 may be on the front side. This allows the washing pump 54, water collection unit 71, drainage pump 62, and water splitter 55 to be compactly arranged in the left-right direction.

[0041] (2) Of the left-right dimension L1 of the cleaning pump 54, the left-right dimension L2 of the water collection section 71, the left-right dimension L3 of the drainage pump 62, and the left-right dimension L4 of the water splitter, the largest dimension is the dimension L1 of the cleaning pump 54. The water collection section 71 and the water splitter 55 and part or all of the drainage pump 62 overlap with the cleaning pump 54 in the front-rear direction. In other words, when viewed from the front-rear direction, the water collection section 71 and the water splitter 55 and part or all of the drainage pump 62 overlap with the cleaning pump 54. In other words, when viewed from above, the water collection unit 71, the water distributor 55, and part or all of the drainage pump 62 are located in the region between a virtual line L11 that passes through the right end of the cleaning pump 54 and extends in the front-to-back direction, and a virtual line L12 that passes through the left end of the cleaning pump 54 and extends in the front-to-back direction. This location includes the water collection section 71, part of the water distributor 55, and the entirety of the drainage pump 62. This allows the washing pump 54, water collection unit 71, drainage pump 62, and water splitter 55 to be compactly arranged in the left-right direction.

[0042] (3) The left-right dimension L1 of the washing pump 54 is within the range of 1.2 to 1.7 times the left-right dimension L4 of the water splitter 55. The left-right dimension L3 of the drainage pump 62 is within the range of 0.5 to 1.1 times the left-right dimension L4 of the water splitter 55. This allows the washing pump 54, water collection unit 71, drainage pump 62, and water splitter 55 to be compactly arranged in the left-right direction.

[0043] (4) The water splitter 55 is located between the washing pump 54 and the drainage pump 62 in the front-to-back direction. In this case, when viewed from the left-to-right direction, the water splitter 55 may or may not overlap with the washing pump 54 or the drainage pump 62. If they overlap, the configuration can be made more compact in the front-to-back direction. The water distributor 55 may or may not overlap the water collection section 71 when viewed from the left or right. If it overlaps, it can be made more compact in the front-to-back direction. This makes it easy to connect the water splitter 55 and the washing pump 54. (5) When the cleaning pump 54 is located behind the water collection unit 71, part or all of the water distributor 55 is located between the water collection unit 71 and the cleaning pump 54 in the front-to-back direction. This makes it easy to connect the water splitter 55 and the washing pump 54. (6) At least part or all of the water supply pipe 43 for supplying cleaning water and the drain pipe 65 for discharging cleaning water are arranged in the left-right direction with respect to the cleaning pump 54, water collection section 71, drain pump 62, and water distributor 55. If the imaginary line L13 passing through the rotation axis of the cleaning pump 54, which has the largest dimension in the left-right direction, is located on the other side (for example, the right side) relative to the center in the left-right direction, then at least part or all of one of the water supply pipe 43 and the drain pipe 65 is positioned on one side (the left side) in the left-right direction relative to the cleaning pump 54, water collection section 71, drain pump 62, and water distributor 55. This allows for a more compact lateral dimension of the device. Furthermore, it enables effective use of the lateral space in the area where the cleaning pump 54, water collection unit 71, drainage pump 62, and water splitter 55 are located.

[0044] (7) When the water collection section 71 and the water distributor 55 overlap in the left-right direction, when viewed from above, part or all of the cleaning pump 54 and the drainage pump 62 are located within the region between a virtual line L21 that passes through the end of the water collection section 71 opposite to the side where the water distributor 55 is located and extends in the front-rear direction, and a virtual line L41 that passes through the end of the water distributor 55 opposite to the side where the water collection section 71 is located and extends in the front-rear direction. In this case, all of the cleaning pump 54 and the drainage pump 62 are located within this region. This allows the washing pump 54, water collection unit 71, drainage pump 62, and water splitter 55 to be compactly arranged in the left-right direction.

[0045] 3. Others (1) When viewed from the left and right, the trap 64 is positioned between the cleaning pump 54 and the drain pump 62. This allows the drain pipe 65 to be positioned close to the cleaning pump 54, thus shortening the length of the drain pipe 65. When viewed from the left and right, the trap 64 overlaps with the cleaning pump 54 but does not overlap with the drain pump 62. (2) The trap 64 is positioned on the opposite side (e.g., the right side) of the area where the washing pump 54, water collection section 71, drainage pump 62, and water splitter 55 are located, in the left-right direction, from the side (e.g., the left side) where the water supply pipe 43 and drainage pipe 65 are located. This prevents the hose 63 connecting the drainage pump 62 and the trap 64 from interfering with the water supply pipe 43 or drainage pipe 65, and allows for easy placement of the hose 63. (3) The trap 64 is arranged perpendicular to the left-right direction and extends in the front-rear direction, with its inlet located on the side where the drain pump 62 is located in the front-rear direction (for example, the front side). This allows the hose 63 to be easily positioned and shortened. (4) The outlet of the trap 64 is located in the front-to-back direction, on the opposite side (e.g., the rear side) from the side (e.g., the front side) where the drain pump 62 is located. This allows the drain pipe 65 connected to the outlet of the trap 64 to be positioned so that it passes on the opposite side (e.g., the rear side) in the front-to-back direction from the side (e.g., the front side) of the arrangement area where the cleaning pump 54, water collection section 71, drain pump 62, and water splitter 55 are located, making it easy to position the drain pipe 65. (5) When viewed from above, a portion of the drain pipe 65 does not intersect with the area where the functional parts, including the cleaning pump 54, the water collection section 71, the drain pump 62, and the water splitter 55, are located, but is positioned close to the area where the functional parts are located. This allows the device to be made more compact. (6) A portion of the water supply pipe 43 and a portion of the drain pipe 65 are arranged vertically. This allows the water supply pipe 43 and the drain pipe 65 to be arranged compactly in the left-right direction.

[0046] Although embodiments have been described above, the invention is not limited to these embodiments, and may be modified in the following ways, for example. Furthermore, embodiments may be combined with modifications, or modifications may be combined with each other. Furthermore, examples not described in the embodiments or modifications, as well as design changes that do not depart from the gist of the invention, are also included in the present invention.

[0047] <Variation> (1) In the embodiment described, a front-opening type dishwasher X was described, but for example, a so-called slide-open type in which the washing chamber can be pulled out may also be used. In this case as well, a lower chamber can be provided below the removable washing chamber, and the functional parts can be arranged in the lower chamber. (2) The dishwasher X was a built-in type installed in the kitchen counter, but it may also be a freestanding dishwasher that is placed on the floor of the kitchen, for example. (3) In the embodiment, a "slim width type" dishwasher was described, but the invention for making the left-right dimensions compact is particularly effective for dishwashers with left-right dimensions of 30 to 45 cm. However, if the left-right dimensions are 30 cm or less, it is not practical from the standpoint of securing the capacity of the washing chamber. (4) In the dishwasher X, the hot air blowing unit 81, exhaust unit 82, operating unit 83, and circuit unit 84 were all located in the upper chamber 13, but some of them (for example, only the operating unit 83) may be located there. (5) The dishwasher X had an upper nozzle body 52 and a lower nozzle body 53, but it may have nozzle bodies in other locations, or it may have only one of the upper nozzle body 52 and the lower nozzle body 53, or it may have nozzle bodies in other locations instead of the upper nozzle body 52 and the lower nozzle body 53. (6) The dishwasher X was equipped with a water splitter 55 to alternately discharge washing water from the upper nozzle body 52 and the lower nozzle body 53, but it may also be configured to discharge washing water simultaneously from the upper nozzle body 52 and the lower nozzle body 53. In this case, the water splitter 55 is not necessary. (7) The washing pump 54 and the drainage pump 62 are directly connected to the water collection section 71, but for example, at least one of the pumps may be connected to the water collection section 71 via a hose or pipe. In this case, one of the pumps may be fixed to the washing chamber body 111, or for example, to the lower cover (base) 105. (8) The lower cover 105 had an opening 105h in the rear wall 105b, but for example it may be constructed with a cutout in the upper part (part of the rear extension 105e), or the height may be reduced as in the front wall 105d to accommodate the water supply pipe 43 and the drain pipe 65. (9) The drain pipe 65 has the side connected to the trap 64 passing behind the cleaning pump 54, but the positions of the cleaning pump 54 and the drain pump 62 may be reversed so that the drain pipe passes in front of them. (10) The water collection section 71 utilizes the protruding portion 111Ad of the washing chamber body 111, but it may also be equipped with a member corresponding to the protruding portion and attached to the washing chamber body 111. (11) The water distributor 55 has a case portion 551 made using the cylindrical portion of the washing chamber body 111, but it may also have a member corresponding to the cylindrical portion, and the member may be attached to the washing chamber body 111. (12) The water collection section 71 is connected to the cleaning pump 54 and the drainage pump 62, but it is sufficient to connect it to at least one of the cleaning pump 54 and the drainage pump 62. Alternatively, the water may be selectively flowed from one outlet to the cleaning pump and the drainage pump. For example, a valve may be used to switch between the cleaning pump side and the drainage pump side. (13) The water collection section 71 is connected to the washing pump 54 and the drainage pump 62, but it may be connected only to the washing pump 54. In this case, the water collection section may be replaced with a drainage outlet section in Invention 1. (14) The left-right dimension L1 of the cleaning pump was configured to be larger than the left-right dimensions L2 and L3 of the water collection section 71 and the drainage pump 62 (that is, the cleaning pump 54 is the functional part with the largest left-right dimension), but other functional parts, such as the water collection section 71 or the drainage pump 62, may have the largest left-right dimension. (15) Parts of the water supply pipe 43 and drain pipe 65 were arranged on both sides in the left-right direction relative to the functional unit, but at least one part of the water supply pipe 43 and drain pipe 65 may be arranged below the functional unit. This may increase the vertical dimension, but it may reduce the horizontal dimension. (16) The rotation axis C1 of the washing pump 54 (which is "L13" in Figure 11) and the rotation axis C2 of the drain pump 62 (which is "L31" in Figure 11) were located on the other side (right side) of the left-right direction relative to the left-right center of the dishwasher X. However, at least one rotation axis of the washing pump 54 and the drain pump 62 may be located in the left-right center, or the rotation axes C1 and C2 may be arranged to intersect a virtual line that passes through the left-right center and extends in the front-back direction. Alternatively, one of the cleaning pump 54 and the drainage pump 62 may be located on one side in the left-right direction, and the other of the cleaning pump 54 and the drainage pump 62 may be located on the other side in the left-right direction. (17) In this embodiment, the cleaning pump 54 and the drainage pump 62 are arranged with their rotation axes C1 and C2 parallel to the front-rear direction. However, for example, as shown in Figure 12(a), the rotation axes C1 and C2 of the cleaning pump 54 and the drainage pump 62 may be arranged along the front-rear direction (intersecting at an angle of 45° or less with respect to the front-rear direction), or as shown in Figure 12(b), the rotation axes C1 and C2 of the cleaning pump 54 and the drainage pump 62 may be arranged along the left-right direction (intersecting at an angle of 45° or less with respect to the left-right direction). The left-right dimension of the functional part is the distance between the right and left ends, as shown in Figure 12. (18) The washing pump 54 and the drainage pump 62 are each driven individually by independent motors (there are two drive means (motors)), but they may also be driven by a single drive means. (19) In this embodiment, the largest dimension among the left-right dimension L1 of the cleaning pump 54, the left-right dimension L2 of the water collection unit 71, and the left-right dimension L3 of the drainage pump 62 was the dimension L1 of the cleaning pump 54. However, the functional unit having the largest dimension may be the water collection unit or the cleaning pump. (20) The functional part having the largest dimensions among the left-right dimension L1 of the cleaning pump 54, the left-right dimension L2 of the water collection section 71, and the left-right dimension L3 of the drain pump 62 is the cleaning pump 54, and part or all of the water collection section 71 and the drain pump 62 may overlap with the cleaning pump 54 in the front-rear direction, part or all of the water collection section 71 may overlap with the cleaning pump 54 in the front-rear direction, and part or all of the drain pump 62 may overlap with the cleaning pump 54 in the front-rear direction. (21) In this embodiment, the largest dimension among the left-right dimension L1 of the cleaning pump 54, the left-right dimension L2 of the water collection unit 71, the left-right dimension L3 of the drainage pump 62, and the left-right dimension L4 of the water distributor (water distribution unit) was the dimension L1 of the cleaning pump 54. However, the functional unit having the largest dimension may be the water collection unit, the cleaning pump, or the water distributor. (22) The functional part having the largest dimensions among the left-right dimension L1 of the cleaning pump 54, the left-right dimension L2 of the water collection section 71, the left-right dimension L3 of the drainage pump 62, and the left-right dimension L4 of the water distributor (water distribution section) is the cleaning pump 54, and part or all of the water collection section 71, the drainage pump 62, and the water distributor 55 may overlap with the cleaning pump 54 in the front-rear direction, part or all of the water collection section 71 may overlap with the cleaning pump 54 in the front-rear direction, part or all of the drainage pump 62 may overlap with the cleaning pump 54 in the front-rear direction, and part or all of the water distributor 55 may overlap with the cleaning pump 54 in the front-rear direction. (23) In this embodiment, the washing pump section, water collection section, and drainage pump section are arranged in the front-to-back direction, but the front-to-back direction may be considered the first direction. In this case, the dimensions in the second direction, which is perpendicular to the first direction and the up-and-down direction, can be made more compact. (24) In this embodiment, the water collection unit, the washing pump unit, and the drainage pump unit are defined as functional units, but other units having functions related to washing may also be included as functional units.

[0048] <<Invention>> The above embodiments and modifications include at least the following inventions: Each of the following inventions is not bound by the inventive features or the configuration of the embodiments of any other invention.

[0049] <Invention 1> 1. Prior art For example, a dishwasher has been proposed in which a rinsing pump is arranged in a left-right direction relative to the washing pump and drainage section in the machine room below the washing tank (see, for example, Japanese Patent Publication No. 2001-238846). 2. Problems that Invention 1 aims to solve The above-mentioned dishwasher has the challenge of being difficult to make more compact in the left-right direction. Invention 1 aims to provide a dishwasher that can be made more compact in the left-right direction.

[0050] 3. Invention 1 The first dishwasher according to Invention 1 is, A washing chamber that houses the object to be washed in a way that allows it to be moved in and out, A lower chamber provided below the washing chamber, A functional unit having a function related to the cleaning of the object to be cleaned and provided in the lower chamber, Equipped with, The aforementioned functional unit is A water collection section having an outlet and a function for collecting washing water, A cleaning pump unit having the function of supplying the cleaning water in the water collection section to the cleaning chamber, A drainage pump unit having the function of discharging the cleaning water in the water collection section from the outlet, It includes at least, The washing pump unit, the water collection unit, and the drainage pump unit are arranged in the front-to-back direction. This makes it possible to make the device more compact in directions perpendicular to the front-to-back direction. The cleaning pump section of Invention 1 is a concept that includes both cases: one in which only a cleaning pump is provided, and another in which a cleaning pump and a case housing the cleaning pump are provided. Furthermore, the drainage pump section of Invention 1 is a concept that includes both cases: one in which only a drainage pump is provided, and another in which a drainage pump and a case housing the drainage pump are provided.

[0051] The second dishwasher according to Invention 1 is a first dishwasher, When the lower chamber is viewed from above, the functional part with the largest dimensions in the left-right direction overlaps, in the front-to-back direction, with part or all of the other functional parts other than the largest functional part. This makes it possible to make the product more compact in the left-right direction.

[0052] The third dishwasher according to Invention 1 is a first or second dishwasher, The washing chamber is provided with a plurality of nozzles for discharging the washing water. The lower chamber is provided with a water distribution unit that has the function of distributing the cleaning water sent from the cleaning pump unit in order to supply it to the plurality of nozzle bodies. When the lower chamber is viewed in the vertical direction, part or all of the water distribution section overlaps with the largest functional section in the front-to-back direction. This makes it possible to make the product more compact in the left-right direction.

[0053] The fourth dishwasher according to Invention 1 is a dishwasher that, in the first to third dishwashers, When the lower chamber is viewed in the vertical direction, a virtual line extending the rotation axis of the cleaning pump in the cleaning pump section and a virtual line extending the rotation axis of the drainage pump in the drainage pump section pass through the water collection section. This makes it possible to make the product more compact in the left-right direction.

[0054] The fifth dishwasher according to Invention 1 is a dishwasher that, in the first to fourth dishwashers, The left-right dimension of the drainage pump section is within the range of 0.4 to 1.5 times the left-right dimension of the water collection section. This makes it possible to make the product more compact in the left-right direction.

[0055] The sixth dishwasher according to Invention 1 is a dishwasher that, in the first to fifth dishwashers, The water collection section is located between the washing pump section and the drainage pump section in the front-to-back direction. This makes it easy to connect the drainage pump unit, the cleaning pump unit, and the water collection unit.

[0056] The seventh dishwasher according to Invention 1 is a dishwasher that, in the first to sixth dishwashers, The drainage pump unit is positioned at the very front of the functional unit. This position the drainage pump, which is susceptible to the effects of food residue, at the very front of the functional unit, making maintenance such as replacing the drainage pump easier.

[0057] The eighth dishwasher according to Invention 1 is a dishwasher that, in the first to seventh dishwashers, A water supply pipe for supplying the aforementioned cleaning water and a drain pipe for discharging it are arranged in the left-right direction relative to the functional unit. This allows for easier installation of water supply and drainage piping, and also enables effective use of the lateral space on both sides of the functional unit.

[0058] The ninth dishwasher according to Invention 1 is a dishwasher that, in the first to eighth dishwashers, The lower chamber has an opening at its front and is equipped with a removable front cover that closes the opening. This enhances the aesthetic appeal of the front of the dishwasher. By simply removing the front cover, maintenance such as replacing the piping connections and drain pump can be performed from the front.

[0059] The tenth dishwasher according to Invention 1 is a dishwasher according to the first to ninth dishwashers, The aforementioned cleaning pump unit includes a cleaning pump with an integrated heater for hot water. This eliminates the need for heater mounting fixtures. It also eliminates the need for space to place a hot water heater inside the washing chamber, making it easier to recover the washing water (reducing the risk of air getting stuck in the washing pump). When a heater is placed inside the washing chamber, a structure (e.g., a cover) is required to prevent food residue from adhering to it, but by equipping the heater to the washing pump, there is no risk of food residue adhering to it, eliminating the need for a cover or similar. Furthermore, it becomes easier to select a heater appropriate for the capacity of the washing chamber.

[0060] The 11th dishwasher according to Invention 1 is a dishwasher according to the 1st to 10th dishwashers, The upper chamber above the washing chamber is equipped with a hot air blowing unit that supplies hot air into the washing chamber. This allows for effective use of the space above the washing room.

[0061] <Invention 2> 1. Prior art For example, a dishwasher has been proposed that includes a hot water heater inside the washing tank (see, for example, Japanese Patent Publication No. 2009-213813). 2. Problems that Invention 2 aims to solve The above-mentioned dishwasher requires a structure that includes a heater inside the washing tank, which presents the challenge of making the inside of the washing tank complex. Invention 1 aims to provide a dishwasher with a simplified washing chamber structure. 3. Invention 2 The dishwasher according to Invention 1 is A washing chamber that houses the object to be washed in a way that allows it to be moved in and out, A heating-equipped cleaning pump installed outside the aforementioned cleaning chamber and It is equipped with. This eliminates the need to place a heater inside the cleaning chamber, simplifying its structure. Furthermore, the elimination of space for a heater makes it easier to design a system for recovering the cleaning water. Easier recovery of the cleaning water, for example, can prevent air from getting trapped in the cleaning pump. Furthermore, when a heater is installed inside the washing chamber, a structure is needed to prevent food residue from adhering to the heater. However, by using a washing pump with a heater, such a structure to prevent food residue from adhering becomes unnecessary. Furthermore, since the heater is installed outside the washing chamber, it becomes easier to select a heater that is appropriate for the capacity of the washing chamber. Invention 2 may or may not have the arrangement configuration described in Invention 1. [Explanation of Symbols]
