This makes it possible to suppress the generation of noise.

[0022] In the twelfth embodiment, in the first to eleventh dishwashers, the circuit unit is provided in a case, the case is configured to be insertable and removable in the front-to-back direction, and the control system cord and the power system cord have a length that allows the case to be inserted and removed in the front-to-back direction. This allows the case to be inserted and removed while the cord is connected.

[0023] The thirteenth embodiment of the dishwasher is a dishwasher according to the first to twelfth embodiments, wherein the washing chamber comprises a washing chamber body having an opening on the front side and fixed to the upper chamber, and a door body that covers the opening of the washing chamber body, and the control system cord is supported at a first fixed position on the side wall of the washing chamber body, and the power system cord is supported at a second fixed position on the side wall of the washing chamber body. This allows the cord to move freely when the case is inserted or removed.

[0024] In the fourteenth embodiment, in the first to thirteenth dishwashers, the control cord passes behind the first fixing position and the power cord passes behind the second fixing position. This allows the cord to be stored inside the dishwasher.

[0025] In a fifteenth embodiment of the dishwasher, in the first to fourteenth embodiment of the dishwasher, the functional part includes a blower that sends air into the washing chamber, and a filter for the blower is attached to the case. This allows the filter to be pulled out when the case is pulled out.

[0026] <Embodiment> 1. Overall 1, the dishwasher X is a so-called front-open type that is used by tilting (opening) the door body 113 and pulling out the baskets 21, 23 inside.

Here, baskets 21, 23 are accommodated in two tiers, upper and lower, with cups, small plates, etc. placed in upper basket 21 and large plates, small plates, bowls, etc. placed in lower basket 23. As shown in Figures 2 to 4, the dishwasher X includes support sections 31 and 32 that support the upper and lower baskets 21 and 23 so that they can be inserted and removed, a washing section 33 that washes the objects to be washed, a blower section 34 that sends air into the washing chamber 11, an exhaust section 35 that exhausts the air within the washing chamber 11, an operation section 36 that accepts user operations, a power supply section for driving the device, and a control section that controls the operation of the device. Here, the power supply unit and the control unit are configured by a circuit unit 37 in which a plurality of electronic components (371) are mounted on one substrate (372). This will be explained in detail below.

[0027] 2. Cleaning Room (1) Cleaning room configuration 1 to 3, the cleaning chamber 11 has a box shape that is long in the vertical direction. The cleaning chamber 11 includes a cleaning chamber main body 111 having an opening on the front side, and a door body 113 for opening and closing the opening of the cleaning chamber main body 111. 4, the cleaning chamber main body 111 is composed of two upper and lower members, a lower main body member 111A and an upper main body member 111B. The lower main body member 111A and the upper main body member 111B are fixed to each other with fasteners such as screws, and the front sides of the lower main body member 111A and the upper main body member 111B are fixed to a pair of frame members 17 that extend vertically and are arranged on the left and right. The door body 113 has its lower side supported by a hinge shaft 171 of the frame member 17, allowing the opening of the cleaning chamber main body 111 to be opened and closed. The door body 113 is opened and closed using a handle 114 on the upper part of the door body 113, as shown in FIGS. 1 and 3. When the handle 114 is operated, an engagement between an engaging member 115 on the inner surface of the door body 113 and an engaged portion 116 on the cleaning chamber main body 111 side is released. In order for the engaging member 115 to engage with the engaged portion 116, a through-hole 131h (see FIG. 9) is provided in the front cover 131 described below, a through-hole 133h (see FIG. 9) is provided in the connecting member 133, and a through-hole 373n (see FIG. 11) is provided in the case 373 of the circuit unit 37. As shown in Figure 1(b), the back surface of the door body 113 also functions as a support part that supports the lower basket 23 from below when it is pulled out from the cleaning chamber main body 111, and has a guide part 113a for the wheels 236 of the lower basket 23 on the back surface.

[0028] (2) Support part The support portions 31 and 32 support the cars 21 and 23 . The upper support part 31 supports the upper basket 21. The upper support part 31 includes a movable support 312 (see FIG. 1(b)) that detachably supports the upper basket 21 and extends in the front-to-rear direction, a fixed support 313 (see FIG. 2 or 3) that is arranged on the inner surface of the side wall 111Bb of the cleaning chamber main body 111 and supports the movable support 312 so that it can slide in the front-to-rear direction, and a fixed body 315 (see FIG. 4) that is arranged on the outer surface of the side wall 111Bb of the cleaning chamber main body 111 and fixes the fixed support 313. As shown in Fig. 2, the lower support part 32 is configured by a stepped portion 321. The stepped portion 321 is provided on the main body lower member 111A, has a low step on the inner side in the left-right direction, and extends in the front-rear direction. The lower car 23 is provided with wheels 236 for movement, and the wheels 236 move in the front-rear direction on the flat area of ​​the stepped portion 321.

[0029] (3) Cleaning section As shown in Figures 2 and 3, the washing section 33 comprises an upper nozzle body 331 for discharging washing water toward the object to be washed placed in the upper basket 21, a lower nozzle body 332 for discharging washing water toward the object to be washed placed in the lower basket 23, a washing pump (not shown) that sucks in washing water stored at the bottom of the washing chamber 11 and discharges it from the outlets of the upper nozzle body 331 and the lower nozzle body 332, an upper piping 333 that connects the washing pump to the upper nozzle body 331, a lower piping 334 that connects the washing pump to the lower nozzle body 332, and a filter 335 that removes food residue and the like contained in the washing water stored at the bottom of the washing chamber 11. The cleaning pump is disposed in the lower chamber 15 below the cleaning chamber 11, and is covered by the right plate 101 and the bottom cover 105 in FIGS. 2 to 4, and is not visible in the drawings. The cleaning pump is supplied with tap water or the like from a water supply source (not shown) via a water supply valve 381 (see FIG. 4).

[0030] 3. Upper chamber (1) Upper chamber configuration The upper chamber 13 is fixed to the cleaning chamber main body 111. Therefore, even if an electrically driven unit is housed in the upper chamber 13, the wiring will not be cut when the door 113 is opened or closed or when the cages 21 and 23 are pulled out. As shown in Fig. 3, the upper chamber 13 is provided so as to protrude forward from the front surface of the washing chamber main body 111. Specifically, the front surface of the upper chamber 13 is located forward of the opening of the washing chamber main body 111. Furthermore, the front surface of the upper chamber 13 is provided at the same position in the front-to-rear direction as the front surface of the door body 113 in the closed state, that is, flush with the front surface of the door body 113. This improves the design of the dishwasher X in the closed state.

[0031] As shown in Figures 4 and 5, the upper chamber 13 is composed of the upper wall 111Ba (upper surface) of the main body upper member 111B of the cleaning chamber main body 111, the front cover 131, the upper plate 104, the right plate 101, the left plate 102, and the rear plate 103. The right plate 101, the left plate 102, the rear plate 103, and the top plate 104 are fixed to the frame material 17, the base portion 111Bh of the main body upper member 111B, and the bottom cover 105 using screws 119. Upper chamber 13 receives power during operation of the dishwasher, i.e., during washing-related operations (including washing and drying operations), and accommodates functional units for executing washing-related operations. Specifically, these units include air blower 34, operating unit 36, and circuit unit 37.

[0032] The pair of frame members 17 extend upward beyond the cleaning chamber main body 111, and the extending portions are connected in the left-right direction by connectors 133. The front cover 131 has a box-shaped portion 131a that is long in the left-right direction and has an open rear side, and a protruding portion 131b that protrudes downward from the rear end of the lower wall of the box-shaped portion 131a. The front surface of the box-shaped portion 131a forms the front surface of the upper chamber 13. As shown in Fig. 9, the protruding portion 131b is provided with a through-hole 131c and a protruding portion 131d. The protruding portion 131d fits into a through-hole 133d of the connector 133. This positions the front cover 131 relative to the connector 133. Screws 139a and 139b are inserted into the through-hole 131c from the front side. This allows the front cover 131 (protruding portion 131b) to be fixed to the connector 133 and the frame material 17 in a positioned state by the screws 139a and 139b. The screw 139b serves both to fix the front cover 131 and the connector 133 to the frame material 17, and this allows the screw 139b to be removed efficiently when inspecting the circuit unit 37, for example.

[0033] (2) Blower 4 and 5, the air blowing section 34 includes an air blower 341 made up of an air blower fan and an air blower motor, and an air blower duct 343 connecting the air blower 341 and the flow path forming section 111Aa of the cleaning chamber 11. An air blowing path through which air flows is formed inside the air blower duct 343 and the flow path forming section 111Aa. The blower 341 and the upstream portion 343a of the air duct 343 are arranged in the upper chamber 13, and the downstream portion 343b of the air duct 343 is arranged in the rear wall 111Bc of the cleaning chamber 11. The flow path forming portion 111Aa of the cleaning chamber 11 is provided on the rear side of the main body lower member 111A, and the air outlet 111Ab is exposed to the inside of the cleaning chamber 11 (see FIG. 2). 4 and 5, the blower 341 is disposed in the center position in the front-rear direction or in a position rearward of the center, and is fixed to the cleaning chamber main body 111. As shown in Fig. 6, the blower 341 is fixed by fitting a protrusion 111Bm on the upper wall 111Ba of the cleaning chamber main body 111 into a through-hole (not shown) in the casing 341a. 7, blower 341 draws air through through-hole 341b in the upper wall of casing 341a and sends the air rearward through air outlet 341c at the rear of casing 341a. This prevents the air drawn in by blower 341 from flowing forward. Therefore, even if circuit unit 37 is disposed in front of blower 341, dust in the drawn air can be prevented from flowing toward circuit unit 37.

[0034] As shown in Figures 6 and 7, the air blowing unit 34 is provided with a heater 345 inside the air blowing duct 343. This allows hot air heated by the heater 345 to be supplied to the cleaning chamber 11. The heater 345 is disposed downstream from the upstream end of the air blowing duct 343 at a distance. As shown in Figure 7(b), the upstream portion 343a of the air blowing duct 343 is made up of a duct main body 346A with an open top and a duct lid body 346B that covers the top of the duct main body 346A. This makes it easy to arrange the heater 345.

[0035] The upstream portion 343a of the air supply duct 343 has a supply portion 347 upstream of the heater 345 for supplying air to the discharge portion 35. This allows air before it is heated by the heater 345 to be supplied to the discharge portion 35. For example, when discharging heated air from the cleaning chamber 11, the heated air from the cleaning chamber 11 can be cooled, and the temperature of the air discharged from the front surface of the upper chamber 13 can be lowered. As shown in FIG. 7(a), the supply portion 347 is provided outside the flow of air discharged from the air outlet 341c of the blower 341. This reduces the amount of air flowing through the supply portion 347, ensuring a sufficient amount of air supplied to the cleaning chamber 11. Furthermore, the center line of the supply portion 347 (the imaginary line L2 in the figure) in plan view is inclined so that the angle θ with respect to the flow of air discharged from the blower 341 (the imaginary line L1 in the figure) is within a range of 30 to 50 degrees. This reduces the resistance to air flowing into the supply portion 347. As shown in FIG. 7(b), the supply portion 347 is inclined so that the lower wall 347a becomes higher as it moves away from the blower 341. This allows the cross section of the downstream portion of the supply portion 347 (the connection portion 347b to which the hose 349 is connected) to gradually decrease, thereby increasing the flow velocity of air flowing through the supply portion 347 and enabling smooth exhaust of air from the cleaning chamber 11. As shown in FIG. 7(a), the supply portion 347 is connected to the discharge portion 35 by a hose 349, and FIG. 7(b) shows a state in which the hose 349 has been removed.

[0036] 4, the blower 34 is disposed on one side (the right side) in the left-right direction. In other words, it is disposed on the opposite side in the left-right direction from the side on which the discharge part 35 is disposed. This ensures a space for accommodating the hose 349 that connects the blower 34 and the discharge part 35. The air duct 343 is fixed by screwing a screw 348 inserted through a through hole of the air duct 343 into a screw hole 111Bp in a boss portion of the upper wall 111Ba of the cleaning chamber main body 111.

[0037] (3) Discharge section The exhaust section 35 exhausts the air inside the cleaning chamber 11. More specifically, the air sent into the cleaning chamber 11 by the blower section 34 is exhausted. 8 and 10, the discharge section 35 includes at least a discharge duct 353 having a communication port 351 communicating with the washing chamber 11 and a discharge port 352 communicating with the outside of the dishwasher X. A discharge path through which the discharged air flows is formed inside the discharge duct 353. Exhaust section 35 uses air sent out from blower 341 as an exhaust means for causing air that has entered exhaust duct 353 from communication port 351 to flow toward exhaust port 352. For this reason, exhaust duct 353 has connection section 354 for connecting to hose 349 (see FIG. 7(a)) that is connected to blower 341. Furthermore, a discharge fitting 355 is attached to the discharge port 352 of the discharge duct 353. In order to show the discharge port 352, the discharge fitting 355 is removed in FIG.

[0038] Exhaust duct 353 is cylindrical and, as shown in Fig. 8, is made up of, for example, two upper and lower members. In this example, these are lower forming member 357 and upper forming member 358. Exhaust duct 353 has a cross section perpendicular to the flow of the exhausted air that is rectangular or has a shape similar to a rectangle that is long in the left-right direction. This allows the upper chamber 13 to be made thinner while ensuring the flow rate of the exhausted air. The exhaust duct 353 has a long, flat shape that is long in the front-to-rear direction. When viewed from above, the exhaust duct 353 has an overall rectangular shape that is long in the front-to-rear direction, and the end opposite the exhaust port 352 has an arc shape. The lower forming member 357 and the upper forming member 358 are joined together, for example, by inserting a screw 359a through a through hole (boss hole) 358e of the upper forming member 358 and screwing it into a screw hole 357h of the lower forming member 357 while the engaging portion 357g of the lower forming member 357 is engaged with the engaged portion 358d of the upper forming member 358.

[0039] The communication opening 351 is formed in the bottom part of a recessed portion 357b that recesses downward from the bottom wall (bottom wall 357a of the lower forming member 357) of the exhaust duct 353. The communication opening 351 is composed of a plurality of through holes formed in the recessed portion 357b. The bottom wall of the exhaust duct 353 (bottom wall 357a of the lower forming member 357) has an inclined region 357c between the recessed portion 357b and the exhaust port 352 that becomes higher as it approaches the exhaust port 352. This reduces the cross-sectional area of ​​the flow path of air from the communication port 351 toward the exhaust port 352, making it possible to increase the flow rate of air exhausted from the exhaust port 352. In other words, air can be exhausted to a position far from the exhaust port 352. A connecting portion 354 extending cylindrically rearward is formed on the end portion of the peripheral wall of the exhaust duct 353 opposite the exhaust port 352 in the front-to-rear direction (the end portion of the peripheral wall 357d of the lower forming member 357). As a result, the communication port 351 is located midway along the flow path from the connecting portion 354 to the exhaust port 352, and the air in the cleaning chamber 11 can be efficiently directed toward the exhaust port 352.

[0040] The exhaust duct 353 has a dispersion (separation) means for dispersing (separating) the air from the blower 34. The dispersion means is composed of a plate-shaped portion 358a having an area facing the inlet 354a from the connecting portion 354. The plate-shaped portion 358a extends downward in a "U" shape from the upper wall of the exhaust duct 353 (the upper wall 358b of the upper forming member 358). This allows the air flowing in from the connecting portion 354 to flow along two separate paths along the plate-shaped portion 358a. The communication port 351 is located in the area surrounded by the "U" shape.

[0041] The exhaust duct 353 has a cylindrical portion 357e that extends downward and is spaced outward from the recessed portion 357b. The cylindrical portion 357e is provided on the bottom wall 357a of the lower forming member 357. As shown in FIG. 6, the cylindrical portion 357e fits into the groove between the double cylindrical portion 111Bd of the upper wall 111Ba of the upper body member 111B of the cleaning chamber body 111, and the inner cylindrical portion of the double cylindrical portion 111Bd fits between the cylindrical portion 357e and the recessed portion 357b. This improves sealing. The exhaust duct 353 is also positioned in the left-right and front-rear directions relative to the cleaning chamber body 111.

[0042] 6, a through-hole 111Be is provided inside the double cylindrical portion 111Bd. This allows communication between the exhaust duct 353 of the exhaust unit 35 and the cleaning chamber 11. When the cylindrical portion 357e is fitted into the double cylindrical portion 111Bd, the through-hole 111Be of the cleaning chamber main body 111 and the communication port 351 of the exhaust unit 35 face each other, reducing resistance when air in the cleaning chamber 11 flows into the exhaust unit 35.

[0043] The exhaust section 35 communicates with the cleaning chamber 11 forward of the center in the front-to-rear direction. This allows the overall length of the exhaust duct 353 to be shortened, and the drive source (air from the blower 341) for exhausting air from the cleaning chamber 11 to be smaller. Alternatively, air can be exhausted from the cleaning chamber 11 without providing a dedicated blower for exhaust.

[0044] The exhaust duct 353 has a protruding portion 357f that protrudes downward from its front portion. The protruding portion 357f is provided on the bottom wall 357a of the lower forming member 357. The protruding portion 357f fits into a recess 111Bf (see FIG. 6) in the upper wall 111Ba of the main body upper member 111B of the cleaning chamber main body 111. This prevents the exhaust duct 353 from rotating relative to the cleaning chamber main body 111 when the cylindrical portion 357e fits into the double cylindrical portion 111Bd. The exhaust duct 353 is fixed to the cleaning chamber main body 111, for example, by inserting a screw 359c through the through hole of the exhaust duct 353 and screwing it into the screw hole 111Bg (see Figure 6) of the main body upper member 111B, with the exhaust outlet fitting 355 and the front part of the exhaust duct 353 extending forward beyond the connecting fitting 133 as shown in Figure 5.

[0045] As shown in Figures 8 and 10(a), the discharge outlet tool 355 has a rectangular cylindrical shape that is long in the left-right direction and thin in the up-down direction. The discharge outlet tool 355 has a plurality of partition walls 355a that divide the internal space. The partition walls 355a are provided at intervals that prevent the user's fingers, etc., from getting inside. The outlet fitting 355 has a rib portion 355b extending up, down, left, and right in the center in the front-to-rear direction. The portion rearward of the rib portion 355b fits into the outlet 352 of the outlet duct 353, and the screw 359b inserted through the through hole 358c of the upper forming member 358 is threaded into the screw hole 353c of the outlet fitting 355, whereby the outlet fitting 355 is attached to the outlet duct 353. 1, the front cover 131 has a through-hole 131e (see FIG. 5) in the front wall 131g for exposing (communicating with) the discharge outlet tool 355 to the outside. Similarly, the connector 133 has a through-hole 133g for the discharge outlet tool 355.

[0046] (4)Operation section The operating unit 36 ​​is provided on the front surface of the upper chamber 13. In other words, it is provided above the door body 113. This allows the user to operate the operating unit 36 ​​without bending over. As shown in FIG. 5, the operation unit 36 ​​includes a plurality of operation buttons 361, such as a power switch for the user to turn the power of the dishwasher X on / off and a selection switch for selecting the desired washing operation, and an operation board 362 on which the plurality of operation buttons 361 are mounted. The operation unit 36 ​​further includes a display unit 363 for displaying selected contents and operating status, an LED 364 that lights up or flashes in the event of an error, and a connector 365 that electrically connects to the circuit unit 37, mounted on the operation board 362.

[0047] The operation board 362 has a rectangular shape that is long in the left-right direction, and is fixed to the inside of the front cover 131 by screws 369 with its main surface perpendicular to the front-rear direction. The operation buttons 361, the display unit 363, and the connector 365 are arranged in the left-right direction, thereby making it possible to reduce the vertical dimension of the operation unit 36. The operation board 362 is arranged inside the box-shaped portion 131 a of the front cover 131 and is fixed to the front wall using screws 369 . The front cover 131 has through holes 131f for the operation buttons 361, the LED 364, and the display unit 363 in the front wall 131g.

[0048] (5)Circuit section 5, the circuit section 37 is disposed in the periphery of the operation section 36, for example, adjacent to the rear side of the operation section 36. This allows the length of the wiring (not shown) connecting the operation section 36 and the circuit section 37 to be shortened. Furthermore, since the upper chamber 13 is fixed to the cleaning chamber 11, there is no risk of the wiring connecting the circuit section 37 and the operation section 36 being cut off. The circuit section 37 is disposed between the operation section 36 and the blower section 34 in the front-rear direction. This allows the wiring (not shown) connecting the circuit section 37 and the blower section 34 to be short. Circuit unit 37 is attached to connector 133. This allows circuit unit 37 to be easily removed by removing connector 133 from frame member 17. In particular, when replacing or inspecting circuit unit 37, this can be done without pulling dishwasher X out from its installation location (for example, a kitchen counter) (without disconnecting water supply and drainage pipes 383, 384). Furthermore, the operating unit 36 ​​is attached to the front cover 131. Therefore, when removing the circuit unit 37, the operating unit 36 ​​can be removed simply by removing the front cover 131, thereby improving workability. As shown in Fig. 9, the front cover 131 can be removed from the frame member 17 and the connector 133 by removing the screws 139a and 139b.

[0049] 5, circuit unit 37 includes electronic components 371 that form the circuit of the power supply unit and control unit, circuit board 372 on which electronic components 371 are mounted, and case 373 that houses circuit board 372. In the figure, multiple electronic components are shown as one block. The circuit unit 37 here includes a sensor 117B (see FIG. 6) that detects whether the door 113 is open or closed, and a locking mechanism 375 that locks the door 113 in the closed state, in the case 373.

[0050] Circuit board 372 is housed in case 373 with its main surface perpendicular to the vertical direction. This allows the vertical dimension of case 373 to be reduced, and also the vertical dimension of upper chamber 13 to be reduced. Circuit board 372 is fixed to case 373 using screws 379, for example.

[0051] The case 373 is box-shaped with an open top and has a rectangular shape that is long in the front-rear direction when viewed from above. As shown in FIG. 11, the case 373 has screw holes 373a in boss portions at the front and left and right corners. As shown in FIG. 9(b), screws 378 that pass through through holes 133b of the bent portion 133a of the connector 133 are threadedly engaged with the screw holes 373a. This allows the circuit unit 37 (case 373) to be detachably (insertable / removable) fixed to the connector 133. In other words, the circuit unit 37 is housed in the upper chamber 13 so as to be removable from the front side. Screws 378 are threadedly engaged from above and below the boss portion 373a on the right side. As shown in FIG. 11, the case 373 has a protrusion 373c and a screw hole 373d on a front wall 373b. As shown in FIG. 9, the protrusion 373c fits into the through hole 133b of the connector 133. A screw 139a (see FIG. 10) for fixing the front cover 131 to the connector 133 is inserted through the through hole 131c of the front cover 131 and the through hole 133c of the connector 133 and screwed into the screw hole 373d. This allows the case 373 to be fixed to the connector 133 while being positioned relative to the connector 133 in the left-right and up-down directions. Furthermore, when inspecting the circuit unit 37, removing the screw 139a that fixes the front cover 131 also removes some of the screws that fix the case 373, allowing the screws that fix the case 373 to be removed efficiently.

[0052] The case 373 has screw holes 373f for fixing the circuit board 372 in boss portions 373g of the bottom wall 373e. The case 373 has a stopper 373h on its bottom wall 373e for use when inserting the circuit unit 37 into the upper chamber 13 from the front side. The stopper 373h has a protruding shape that is open at the rear, such as a "U" shape, a "V" shape, or a similar shape. As shown in FIG. 12, the stopper 373h receives from the rear side a protruding portion 111Bj formed on the front end of the upper wall 111Ba of the cleaning chamber main body 111 (main body upper member 111B), and then abuts or approaches the protruding portion 111Bj at the front end of the upper wall 111Ba. This prevents the circuit unit 37 from being inserted too far, causing the case 373 to collide with the blower unit 34. The stopper 373h has a "U" or "V" shape that opens at the rear, and functions as a guide that guides the case 373 to a predetermined position in the left-right direction in relation to the protruding portion 111Bj.

[0053] The case 373 has a stopper 373j on its rear wall 373k for use when inserting the circuit unit 37 into the upper chamber 13 from the front. Two stoppers 373j are provided at intervals in the left-right direction. This allows the stopper function to be exerted even if the case 373 is inserted at an angle relative to the front-to-rear direction. The stopper 373j is composed of a pair of protrusions 373q that bulge rearward and extend up and down. The pair of protruding portions 373q are formed with a gap therebetween in the left-right direction, and the gap between the pair of protruding portions 373q in the left-right direction becomes wider toward the rear. When the circuit unit 37 is inserted from the front side to a predetermined position, the stopper 373j comes into contact with or comes close to the standing plate portion 111Bk formed on the upper wall 111Ba of the cleaning chamber main body 111 (main body upper member 111B), as shown in Fig. 12. This prevents the circuit unit 37 from being inserted too far and causing the case 373 to collide with the blower unit 34. The upright plate portion 111Bk is provided with its main surface perpendicular to the front-rear direction and is connected to the rear end of the portion of the support portion 111Bn that extends in the front-rear direction, thereby preventing the upright plate portion 111Bk from being easily damaged.

[0054] The case 373 has a recessed portion 373m extending in the vertical direction in the rear wall 373k. Two recessed portions 373m are provided at a distance in the horizontal direction. The recessed portion 373m is formed between a pair of protruding portions 373q of the stopper 373j and is configured as a groove portion extending in the vertical direction. When the circuit unit 37 is inserted into the recessed portion 373m from the front side to a predetermined position, as shown in FIG. 12, a convex portion 111Br formed on the upright plate portion 111Bk of the upper wall 111Ba of the cleaning chamber main body 111 (main body upper member 111B) enters from the rear side. This positions the case 373 in the horizontal direction. In this state, the convex portion 111Br is located above the lower end of the recessed portion 373m, thereby also functioning as a positioning member in the vertical direction.

[0055] As shown in FIG. 12, the upper wall 111Ba of the cleaning chamber main body 111 (main body upper member 111B) has a support portion 111Bn that supports the case 373 from below. The support portion 111Bn is composed of ribs that extend upward in a grid or ladder shape. An imaginary plane including the upper edge of the support portion 111Bn is flat. This allows the circuit unit 37 to be inserted smoothly into the upper chamber 13 by placing it on the support portion 111Bn and inserting it.

[0056] The sensor 117B is a magnetic sensor that detects the magnetism of the magnet 117A (see FIG. 1(b)) of the door body 113. The sensor 117B is fixed to a fixing portion 373r in the case 373 with a screw or the like. The locking mechanism 375 is provided with a microswitch that reacts to the engaging member 115 of the door body 113, and when operation starts, locks the engagement of the engaging member 115. The locking mechanism 375 is fixed to a fixing portion 373t inside the case 373 with a screw or the like.

[0057] 4. Removing the circuit The attachment of the circuit section 37 will be described mainly with reference to FIGS. Removal can be achieved by reversing the installation procedure, so only installation will be described here. (1) Fixing the circuit unit to the connector The case 373 of the circuit section 37 is fixed to the connector 133 . Fixation is performed by inserting a screw 378 shown in FIG. 9(b) through a through hole 133b formed in the bent portion 133a of the connector 133 and screwing it into a screw hole 373a of the case 373 shown in FIG.

[0058] (2) Insert the circuit part into the upper chamber The connector 133 to which the circuit section 37 is attached is inserted into the upper chamber 13, more specifically, between the pair of frame members 17 above the cleaning chamber main body 111, as shown in FIG. 13(a). In this case, as shown in FIG. 12, a support portion 111Bn is formed on the upper wall 111Ba of the cleaning chamber main body 111, and its front end portion 111Bq is inclined upward toward the rear, so that the case 373 can be easily inserted by simply placing the bottom wall 373e of the case 373 on the support portion 111Bn and moving it rearward. In addition, the frame material 17 has a rear bent portion 173 formed in the plate-shaped portion 172, which bends inward in the left-right direction. Therefore, by simply abutting the right wall 373p of the case 373 against the rear bent portion 173 and moving it rearward, the case 373 can be inserted into a predetermined position or a position close to the predetermined position. Furthermore, when the rear side of the case 373 tilts to the right while the right wall 373p of the case 373 is abutting against the rear bent portion 173, it abuts against the right plate 101, preventing it from shifting further to the right, and the right plate 101 functions as a guide. A stopper 373j is provided on the rear wall 373k of the case 373, and the spacing between a pair of protrusion portions 373q of this stopper 373j in the left-right direction becomes wider toward the rear, so that even if the case 373 is shifted in the left-right direction, the convex portion 111Br of the cleaning chamber main body 111 can easily fit between the pair of protrusion portions 373q. The case 373 is inserted until the connector 133 abuts against the front bent portion 174 of the frame material 17. This state is shown in Figure 13(b). If the case 373 is inserted too far, a stopper 373h (see Figure 11(a)) on the front side of the bottom wall 373e of the case 373 abuts against the protruding portion 111Bj of the cleaning chamber main body 111. Furthermore, at the rear side of the case 373, the erected plate portion 111Bk of the cleaning chamber main body 111 abuts against a stopper 373j on the rear wall 373k of the case 373.

[0059] (3) Fixing the connector In the state shown in Figure 13(b), the screw 138 can be inserted through the communicating hole 133e of the connector 133 and screwed into the screw hole 174a of the front bent portion 174 of the frame material 17, thereby fixing the connector 133 to the frame material 17.

[0060] (4) Fixing the front cover (operating part) The front cover 131, to which the operation unit 36 ​​is fixed, is placed from the front side and fixed using screws 139a and 139b. At this time, as shown in FIG. 9(b), the convex portion 131d of the front cover 131 is fitted into the through-hole 133d of the connector 133. This allows the front cover 131 to be positioned relative to the connector 133. As shown in FIG. 9, the screws 139b are inserted through the through holes 131c on both the left and right sides of the front cover 131 and the through hole 133c of the connector 133, and are screwed into the screw holes 174a of the front bent portion 174 of the frame material 17, as shown in FIG. 12. As shown in FIG. 9, the screw 139a is inserted through a through-hole 131c at the center of the front cover 131 and a through-hole 133c of the connector 133, and is screwed into a screw hole 373d of the case 373 of the circuit unit 37. In this way, the front cover 131, the frame material 17, and the case 373 can be fixed together using the screws 139a and 139b.

[0061] 5. Wiring 4 to 6, etc. do not show cords connecting detection means, such as sensors for detecting temperature and hot water, and sensor 117B (see FIG. 6) for detecting the opening and closing of door body 113, to circuit unit 37, or cords connecting drive means, such as pump, heater 345, blower 341, etc., to circuit unit 37, but the wiring of the cords will be explained using FIG. 15 and FIG. 16.

[0062] The circuit section 37 includes a control circuit that controls the functional sections related to the cleaning operation, as well as a power supply circuit that supplies power to the functional sections. The control circuit and power supply circuit are configured by mounting multiple electronic components (shown as one block in FIG. 6 and omitted in FIGS. 15 and 16) on a circuit board 372. The control circuit is connected to the detection means via a control system cord 38, and the power supply circuit is connected to the drive means via a power system cord 39. In Figures 15 and 16, the "one" cord shown as cords 38 and 39 includes both a bundle of multiple cords and a single cord. Connection terminals 382, ​​391 are provided at one end of the power supply cord 39 and the control cord 38, and the connection terminals 382, ​​391 are detachably connected to connection terminals mounted on the circuit board 372. The other end of the control cord 38 is connected to a detection means or the like, and the other end of the power supply cord 39 is connected to a functional unit (drive means) or the like. It should be noted that power supply cord 39 is primarily connected to the driving means of the functional unit, and control cord 38 is primarily connected to the detection means, but from the viewpoint of electrical characteristics (voltage), power supply cord 39 may be a cord that connects to electrical components to which a voltage of 12 V or more is applied, and control cord 38 may be a cord that connects to electrical components to which a voltage of less than 12 V is applied (for example, a cord connected to blower 341 is a control cord).

[0063] 15 and 16, the control system cord 38 and the power system cord 39 are spaced apart. This prevents noise from being generated in the current flowing through the control system cord 38. In other words, the control system cord 38 prevents noise from being generated due to the influence of the power system cord 39. The distance between the control system cord 38 and the power system cord 39 is, in other words, a distance that prevents noise generated in the power system cord 39 from entering the control system cord 38. The term "separated" refers to a state in which the control system cord 38 and the power system cord 39 are separated from each other when the noise generated when the control system cord 38 and the power system cord 39 are arranged as a bundle is reduced to 50% or less by separating the control system cord 38 and the power system cord 39. In this case, the minimum separation distance is the distance between the control system cord 38 and the power system cord 39 when the noise is 50% of the noise generated when the control system cord 38 and the power system cord 39 are arranged as a bundle. From this perspective, even if the control system cord 38 and the power system cord 39 are partially close to each other, they can be said to be separated as long as the noise is 50% or less.

[0064] There are a plurality of connection terminals 382 for the control system cords 38 along one side in the left-right direction (here, the left side) of the circuit board 372, and there are also a plurality of control system cords 38 (here, there are three bundles, and they are referenced as "38A," "38B," and "38C," and when there is no need to distinguish between the cords, they are referenced as "38." The control system cord 38 extends rearward along the front-to-rear direction on one side of the circuit board 372 in the left-to-right direction, outside the circuit board 372, then extends to the other side in the left-to-right direction (here, the right side) from the rear side of the circuit board 372, away from the circuit board 372, and extends downward along the (right) side wall 111Bb of the cleaning chamber main body 111.

[0065] The control system cord 38A branches off from the other control system cords 38B and 38C at a branch point 38a located above the center of the device in the vertical direction, turns back to pass behind the branch point 38a (see FIG. 15), heads upward along the (right) side wall 111Bb, and then advances to one side in the horizontal direction on the top wall 111Ba of the cleaning chamber main body 111. Here, the control system cord 38A includes at least two cords, one of which is connected to the air blower 341 and the other to a sensor (thermistor). Of the multiple control system cords 38 that run downward from branch point 38a along side wall 111Bb, control system cord 38B runs directly downward, passes under the cleaning chamber main body 111 (main body lower member 111A), and connects to the water distributor's microswitch and a sensor (thermistor) that detects the temperature of the hot water (cleaning water). The control system cord 38C flows directly downward from the branch point 38a, branches off from the control system cord 38B at the branch point 38b (see Figure 15) below the center of the device in the vertical direction, flows forward along the cleaning chamber main body 111, and then connects to a sensor (float part) that detects the water level in the cleaning chamber 11. Even if the control system cord 38 has a plurality of cords bundled together, the applied voltage is low, so that noise sufficient to cause false detection is not generated.

[0066] There are a plurality of connection terminals 391 for the power cords along the other side in the left-right direction (here, the right side) of the circuit board 372, and there are also a plurality of power cords 39 (here, there are three bundles, and they are referenced as "39A," "39B," and "39C," and when there is no need to distinguish between the cords, they are referenced as "39." The power cord 39 extends rearward along the front-to-rear direction on the other side of the circuit board 372 in the left-to-right direction, outside the circuit board 372, and after leaving the board accommodating section 373u of the case 373, curves and extends downward so as to protrude forward along the (right) side wall 111Bb of the cleaning chamber main body 111.

[0067] The power cords 39A and 39B branch off from another power cord 39C at a branch point 39a above the center of the device in the vertical direction, curve toward the rear, and extend in the front-to-rear direction along the (right) side wall 111Bb to the rear end. When the power cord 39A reaches its rear end, it splits off from the power cord 39B at a branch point 39b, heads upward, and then travels along the upper wall 111Ba of the cleaning chamber main body 111 to one side in the left-right direction to connect to a sensor (thermistor) 392 and a fuse 393. The power cord 39B that has reached the rear end branches off from the power cord 39A at a branch point 39b, and after heading downward, is led out of the aircraft as a power cord 394. The power cord 39C runs downward from the branch point 39a along the side wall 111Bb, extends diagonally backward, and connects to the pump, motor, etc. on the lower side of the cleaning chamber main body 111 from near the center in the front-to-back direction downward.

[0068] Most of the multiple connection terminals 382 to which the control cords 38 are connected are located on one side (left side) of the rectangular circuit board 372 in the short direction (left-right direction), and most of the multiple connection terminals 391 to which the power cords 39 are connected are located on the other side (right side) of the circuit board 372 in the short direction. This makes it easy to separate the control cords 38 and the power cords 39 by 5 cm or more in the left-right direction above the cleaning chamber main body 111. Note that the majority, in terms of percentage, means that it is within the range of 70 to 100% of the total number. On the right side wall 111Bb of the cleaning chamber main body 111, the power cord 39 is arranged on the front side, and the control cord 38 is arranged on the rear side. This makes it easy to separate the control cord 38 and the power cord 39 in the front-to-rear direction. In particular, because the cleaning chamber main body 111 has a rectangular shape that is long in the front-to-rear direction when viewed from above, it is easy to separate the control cord 38 and the power cord 39 by 5 cm or more in the front-to-rear direction.

[0069] As shown in FIG. 13, the case 373 is configured so as to be insertable and detachable in the front-rear direction, that is, so as to be removable from the front side. The control system cord 38 and the power system cord 39 are fixed (or supported at support positions) at fixing positions A and B on the right side wall 111Bb of the cleaning chamber main body 111 on their way to the other side, and the length of the cords from the rear wall 373k of the substrate accommodating section 373u in the case 373 to fixing positions A and B is longer than the amount of movement of the case 373 when removing it. In other words, the control system cord 38 and the power system cord 39 have a length that allows the case 373 to be inserted and removed in the front-to-rear direction. This makes it possible to insert and remove the case 373 while the control system cord 38 and the power system cord 39 are connected and without any pulling load acting on the cords. The "detached" state in this description of "detachable" means that case 373 can be removed and control system cord 38 and power system cord 39 can be disconnected from circuit board 372. Fixed position A corresponds to an example of the "second fixed position" of the present invention, and fixed position B corresponds to an example of the "first fixed position" of the present invention.

[0070] The control system cord 38 and the power system cord 39 are fixed at fixing positions A and B using fixing devices (not shown) such as cable ties, for example, and the fixing devices are fixed with screws or the like to a fixed body 315 that supports the upper car 21. Therefore, fixing positions A and B of the control system cord 38 and the power system cord 39 are on the fixed body 315, the power system cord 39 is supported and fixed at a position forward of the center of the fixed body 315 in the front-to-rear direction, and the control system cord 38 is supported and fixed at a position close to the center of the fixed body 315 in the front-to-rear direction. The control system cord 38 and the power system cord 39 have curved portions 38c, 39c that curve so as to bulge rearward at least between the board accommodating portion 373u of the case 373 and the fixing positions A, B. This allows the power system cord 39 and the control system cord 38 to be easily accommodated between the right plate 101, the upper plate 104, and the cleaning chamber 11. Furthermore, the length in the vertical direction can be made more compact than if the cord were made straight.

[0071] When viewed from the right side in the left-right direction, fixing position A for the power cord 39, which has a connection terminal 391 at the other left-right end (right end) of the device and circuit board 372, is located forward of the rear end of the case 373 (board accommodating portion 373u) in the front-to-rear direction. In particular, fixing position A is located forward of the rear wall 373k of the case 373 in the inserted state by half the distance between the rear wall 373k of the board accommodating portion 373u of the case 373 when the case 373 is pulled out and in a position where the cords 38, 39 can be removed, and the rear wall 373k of the case 373 when the case 373 is fully inserted. This reduces slack (play) in the power cord 39 located between the circuit board 372 and fixing position A when the case 373 is inserted (stored), preventing it from becoming entangled with the control cord 38 when the case 373 is removed.

[0072] When viewed from the right side in the left-right direction, the fixing position B of the control system cord 38, which has the connection terminal 382 at one end (left end) of the device and circuit board 372, is located in the front-rear direction around the rear end of the board accommodating portion 373u of the case 373. In particular, because the connection terminal 382 is located at one end in the left-right direction, the distance from the rear wall 373k of the case 373 to the fixing position B can be made longer in the control system cord 38. This reduces slack (play) in the inserted state of the control system cord 38 located between the circuit board 372 and the fixing position B, preventing the control system cord 38 from becoming tangled with the power system cord 39 when the case 373 is removed.

[0073] The power cord 39 is located further forward than the control cord 38. This prevents the power cord 39 and the control cord 38 from becoming tangled when inserting or removing the case 373.

[0074] 15 and 16, the case 373 has a support portion 373v, which is integral with or separate from the case 373 and which supports the control system cord 38 so that the control system cord 38 can slide in the longitudinal direction, between a rear wall 373k of the board housing portion 373u and the blower 341. This prevents the control system cord 38 from getting tangled with other parts. At branching points 38a, 38b, and 39b, the cords 38 and 39 are supported before branching by, for example, fixtures, hooks, etc. Also, at points other than branching points 38b and 39b and fixing positions A and B, the cords 38 and 39 are supported by hooks 379, etc.

[0075] Although the embodiment has been described above, the present invention is not limited to this embodiment, and the following modifications may be made, for example: Furthermore, the embodiment and the modifications may be combined, or the modifications may be combined with each other. Furthermore, examples not described in the embodiments and modifications, and design changes within the scope of the present invention are also included in the present invention.

[0076] <Modification> 1. Dishwasher (1) In the embodiment, the dishwasher X is of a front-open type, but it may also be of a so-called slide-open type, in which the washing chamber is pulled out. In this case, too, an upper chamber can be provided above the removable washing chamber. (2) Dishwasher X is a type that is built into a kitchen counter, but it may also be a freestanding dishwasher Y that is placed on the floor of a kitchen or the like, as shown in Fig. 14. In this case, a connection portion 104a for connecting a pipe from a water supply source may be provided on top plate 104. (3) In dishwasher X, all of the air blower 34 (air blower 341, heater 345), operation unit 36, and circuit unit 37 are arranged in the upper chamber 13, but it is sufficient that at least one of air blower 341, heater 345, operation unit 36, and circuit unit 37 is arranged, and it is not necessary that all of air blower 341, heater 345, operation unit 36, and circuit unit 37 are arranged. In consideration of the operability of operation unit 36, it is preferable to provide operation unit 36 ​​on the front, and in this case, it is sufficient that at least one of air blower 341, heater 345, and circuit unit 37 is arranged in the upper chamber. Furthermore, the water supply valve 381 connected to the circuit section 37 may be disposed in the upper chamber 13. This allows the wiring connecting the circuit section 37 and the water supply valve 381 to be short.

[0077] 2. Upper chamber (1) The upper chamber 13 utilizes the upper wall 111Ba (upper surface) of the upper member 111B of the cleaning chamber main body 111, the upper plate 104, the right plate 101, the left plate 102, and the rear plate 103, but it may also utilize a dedicated box-shaped member with an open front. (2) The front surface of the upper chamber 13 is located forward of the opening of the cleaning chamber main body 111, but it may be flush with the opening of the cleaning chamber main body 111, or may be located forward of the opening and rearward of the door body 113 in the closed state. However, considering the operability of the operating unit 36, it is preferable that the front surface be flush with or near the door body 113 in the closed state of the cleaning chamber 11.

[0078] 3. Air blower (1) The air blower 341 blows air backward, but may be arranged so that the air is discharged toward the left side opposite the side (right side) where the circuit unit 37 is located. In this case, the air blower duct 343 may be arranged on the left side wall 111Bb of the cleaning chamber main body 111 or on the rear wall 111Bc. (2) The air duct 343 is provided from the upper wall 111Ba to the rear wall 111Bc of the cleaning chamber main body 111, but for example, multiple air ducts (e.g., two or three) may be provided from the upper wall 111Ba to the left and right side walls 111Bb and further to the rear wall 111Bc. In this case, air can be supplied evenly to the cleaning chamber 11. (3) The air blower 34 is provided with the heater 345 in the upper chamber 13. However, if the length of the wiring is not an issue, the heater 345 may be disposed on the rear wall 111Bc side of the air blower duct 343. However, in consideration of thermal deterioration of the air blower 341, it is preferable to provide the heater 345 downstream of the air blower 341. (4) The air duct 343 uses a cylindrical body made of resin or the like, but a hose (a heat-resistant hose when the temperature is high) may also be used. (5) The air blower duct 343 has one inlet that receives air discharged from the air outlet 341c of the blower 341, and then a flow path branches off to supply air to the exhaust section 35. However, the air blower duct 343 may have two inlets, with the flow path branching off independently from each inlet. In this case, by adjusting the size of the two inlets, the air inside the cleaning chamber 11 can be exhausted while ensuring the amount of air blown into the cleaning chamber 11. (6) In FIG. 7 and other figures, the blower 341 does not have a filter provided in the through-hole (inlet) 341b of the casing 341a, but a filter covering the through-hole may be provided. 17, the filter 41 may be provided integrally or separately from the removable case 373. This allows the filter 41 to be pulled out simultaneously when the case 373 is pulled out, making it easy to clean the filter 41.

[0079] 4.Discharge section (1) The exhaust section 35 exhausts air from the cleaning chamber 11 using the air discharged from the blower section 34, but it may also exhaust air from the cleaning chamber 11 using, for example, a blower separate from the blower section 34. (2) The exhaust unit 35 is connected to the blower unit 34 via the hose 349, but may be connected via a pipe (duct), for example. (3) The discharge section 35 and the blower section 34 are connected via the hose 349. However, for example, the lower forming member 357 of the discharge section 35 and the upstream section 343a of the blower duct may be formed as a single molded product using resin.

[0080] 5.Operation section (1) In the operation unit 36, the operation buttons 361, the display unit 363, the LEDs 364, etc. are mounted on a single operation board 362, but these may be mounted on multiple boards. When the board is divided into two boards, the discharge unit 35 may be disposed between the two boards. (2) The operation unit 36 ​​is fixed in a housed state within the front cover 131, but may be fixed to the connector 133, for example. (3) The operation unit 36 ​​is equipped with electronic components related to operation. For example, electronic components for a circuit that generates a drive power source for driving the operation unit 36 ​​may be equipped.

[0081] 6.Circuit section (1) The case 373 is open at the top, but may be provided with a cover member, which can prevent dust from entering. (2) The case 373 is fixed to the connector 133, but it may be fixed to the cleaning chamber main body 111, or it may be fixed to the frame material after the case is inserted to a predetermined position. (3) The stopper 373h is U-shaped, but its shape is not particularly limited as long as it abuts against the protruding portion 111Bj on the cleaning chamber main body 111 when the case 373 is inserted to a predetermined position. (4) The circuit unit 37 has two stoppers 373h, 373j, but only one of the two stoppers 373h, 373j may be provided. Also, for example, if there is a distance between the case 373 and the blower 34, the circuit unit 37 may not have a stopper. (5) To position the case 373 in the vertical direction, the cleaning chamber main body 111 has a convex portion 111Br, which is located above the concave portion 373m at the rear of the case 373. However, for example, the convex portion 111Br may be arranged to face the upper ends of the left and right side walls (373p, etc.) of the case 373 from above. [Explanation of symbols]
