When the user grasps the operation member 80 and slides the operation member 80 rightward in the closed state of the lid 36 as shown in FIG.
As shown by arrows, the second locking member 73 slides in the same direction, whereby in the link mechanism 82, the first link 83 rotates counterclockwise around the screw 87. And the second links 84 and 85 push the first locking members 67 and 68 outward.

Thus, the first locking locking member 6
Reference numerals 7 and 68 denote engagement portions 67a and 68a at the leading end portions which enter the recesses 72 of the cleaning tank upper frame 8 to engage with the upper frame 8, and thus lock the lid 36 in the closed state. I do. As shown in FIGS. 4 and 15, the second lock locking member 73 causes the engaging portion 75 to enter below the protrusion 78 to be engaged with the protrusion 78. Yes, this also locks the lid 36 in the closed state.

In the lock detecting means 102, the magnet 77 comes close to the reed switch 103, whereby the reed switch 103 is turned on. That is, the lock of the closed state of the lid 36 is detected, and a lock detection signal is output. I do.

On the other hand, from these states, when the user grasps the operation member 80 and slides it leftward, as shown in FIG. 1, the second locking locking member 73 slides in the same direction. Accordingly, in the link mechanism 82, the first link 83 rotates clockwise around the screw 87, and
Links 84 and 85 are first locking members 67 and 6
Pull back 8 inward.

Thus, the first locking locking member 6
Reference numerals 7 and 68 disengage the engaging portions 67a and 68a at the distal ends from the concave portions 72 of the cleaning tank upper frame 8 to release the engagement with the upper frame 8. The second locking member 73 releases the engagement portion 75 from below the projection 78 to release the engagement with the projection 78, and the second locking engagement member 73 closes the lid 36. The state is unlocked.

Further, the lock detecting means 102
Then, the magnet 77 is separated from the reed switch 103, whereby the reed switch 103 is turned off, that is, the lock detection of the closed state of the lid 36 is stopped (lock release is detected), and the output of the lock detection signal is stopped. You.

Then, as shown in FIG. 12, when the user lifts the front cover 38 by putting his / her hand on the handle portion 64, the rear cover 37 is also lifted integrally therewith, and the rear cover 37 is lifted. 37 rotates upward about the shaft 43 of the hinge member 41. Next, if the front cover 38 is lowered from this state,
When the front lid 38 is pivoted downward from the portion connected to the rear lid 37 by the shaft 40, the lid 36 is folded in two. In this state, the front lid 3 continues.
By pushing back the rear cover 8 and the rear cover 37, the opening on the upper surface of the cleaning tank 6 is opened as shown in FIG.

When the lid 36 is opened, the magnet 94 is separated from the reed switch 95 in the lid opening / closing detecting means 93, whereby the reed switch 95 is turned off.
That is, detection of the closed state of the lid 36 stops (opening is detected).
Then, the output of the close detection signal is stopped.

Thereafter, when the user puts his hand on the handle portion 64 and pulls the front cover 38 forward, the rear cover 37 rotates downward around the shaft 43 of the hinge member 41 while the front cover 37 rotates. When the body 38 pivots forward from the portion connected to the rear lid 37 by the shaft 40, the lid 36 is flattened as shown in FIG. Cover and close the opening.

Accordingly, the packing 58 on the back surface of the rear cover 37 and the packing 59 on the back surface of the front cover 38 seal water between the cover 36 and the step 14 of the upper frame 8. The packing 60 is provided between the front end face of the rear lid 37 and the front lid 38.
A water seal is formed between the rear end portion and the rear end portion. The lid opening / closing detecting means 93 turns on the reed switch 95, that is, detects that the lid 36 is closed, and outputs a closing detection signal.

FIG. 17 shows the control contents of the control device 108. The control device 108 controls the dishwasher 5
When the power is turned on by inserting a plug (not shown) into a power outlet, the operation starts (starts). First, the storage means, in this case, EEP
The start prohibition flag stored in the ROM is read (step S1).

Next, it is determined whether or not the power switch of the operation panel (not shown) has been turned on (step S2). If it is determined that the power switch has not been turned on (NO), it is determined whether the lid 36 has been opened or closed. (Step S3).

FIG. 18 shows the details of the judgment of the opening / closing of the lid 36. That is, the judgment of the opening / closing of the lid 36 is made by the reed switch 95 of the lid opening / closing detecting means 93 and the reed switch 103 of the lock detecting means 102. Both are turned off (the unlocking of the lid 36 is detected and the opening is further detected), and then both are turned on (the closing of the lid 36 is detected and the locking is further detected). In step S3, it is determined whether the lid 36 has been opened and the tableware has been stored or removed, and then the lid 36 has been closed and locked. Will be.

In step S3, if it is determined that both the reed switch 95 and the reed switch 103 are both off and then not on (NO), the process returns to step S2, and conversely. If it is determined that both the reed switch 95 and the reed switch 103 are both turned off and then turned on (YES), the start prohibition flag is set to "0" (step S4). Then, the process returns to step S2.

If it is determined in step S2 that the power switch has been turned on, then it is determined whether or not the start switch of the operation panel has been operated (step S5). If not (NO), it is determined whether the lid 36 is open or closed (step S).
6). The opening / closing determination of the lid 36 in step S6 is the same as that in step S3, and therefore, the content shown in FIG. 18 is determined.
6, the tableware is stored or removed, and thereafter, it is determined whether the lid 36 is closed and locked.

In step S6, if it is determined that both the reed switch 95 and the reed switch 103 are both off and then not on (NO), the process returns to step S5, and conversely. If it is determined that both the reed switch 95 and the reed switch 103 are both turned off and then turned on (YES), the start prohibition flag is set to "0" as in step S4 ( Step S7), and return to step S5.

If it is determined in step S5 that the start switch has been operated, it is next determined whether or not the start inhibition flag is "0" (step S8).
If it is determined to be “0” (YES), the dishwasher 5
Operation (washing, rinsing, drying) (step S
9).

Further, after step S9, it is determined whether or not it is time to end the operation (step S10). In this step S10, it is determined that the time to end the operation has not come (NO). While the operation is being performed, the process returns to step S9, but it is time to end the operation (YES).
If it is determined that the operation is completed, the operation is terminated, and the start prohibition flag is set to "1" (step S11).

Thereafter, it is determined whether or not a predetermined time, for example, 30 minutes, has elapsed (step S12). If it is determined that the time has elapsed (YES), the power is turned off (step S13), and Return to S1.

If it is determined in step S8 that the start prohibition flag is not "0" (NO), for example, an abnormality is displayed on the display unit of the operation panel and the buzzer 113 is operated. Then, an abnormality is notified (step S14), and thereafter, the opening / closing of the lid 36 is determined (step S15). The judgment of the opening / closing of the lid 36 in step S15 is the same as that in steps S3 and S6.
The content shown in FIG. 18 is determined, and in this step S15, it is determined whether the lid 36 is opened and the tableware is stored or removed, and then the lid 36 is closed and locked. That is,
In this case, the reed switch 95 and the reed switch 103
That is, it is determined whether or not both have been normally operated.

If it is determined in step 15 that both the reed switch 95 and the reed switch 103 are both turned off and then turned on (YES), the abnormality notification performed in step S14 is notified. The operation is stopped (step S16), the start prohibition flag is set to "0" as in steps S4 and S7 (step S17), and the process returns to step S5.

In step S15, the reed switch 9
If it is determined that both the switch 5 and the reed switch 103 are both off and then not on (NO), then in this case, it is determined whether the power switch has been turned off. Then, if it is determined that no operation has been performed (step S18), the process returns to step S15, but if it is determined that the operation has been performed (YES), the process returns to step S1.

Further, while it is determined in step S12 that 30 minutes have not elapsed (NO), it is determined whether the lid 36 is open or closed (step S19). This step S19
The determination of opening and closing of the lid 36 is the same as that in steps S3, S6, and S15. Therefore, the content shown in FIG. 18 is determined. In step S19, the lid 36 is generally
Is opened and the tableware is taken out, and thereafter, it is determined whether or not the lid 36 is closed and locked.

In step S19, if it is determined that both the reed switch 95 and the reed switch 103 are both off and then not on (NO), the process returns to step S5, and conversely. If it is determined that both the reed switch 95 and the reed switch 103 are both turned off and then turned on (YES), the start inhibition flag is set to "0" (step S20). It returns to step S5.

FIG. 19 shows the contents of the interrupt processing that is performed as needed during the operation (main routine) of the control device 108 described above. This interrupt processing checks the reed switch 95 and the reed switch 103, and determines whether the reed switch 95 is off and the reed switch 103 is on (step T1). If not (NO), the process returns to the main routine.
If so (YES), step S1
4, an abnormality notification similar to S16 is issued (step T2), and the progress of the operation is stopped (step T3).

In addition, although not shown, the control device 108 controls the reed switch 1 during operation of the dishwasher 5.
As soon as 03 is turned off, the operation of the dishwasher 5 is immediately stopped.

As described above, in this configuration, the lid 36 is of a vertically rotating type which does not require the provision of a guide rail, but is folded into two by the rear lid 37 and the front lid 38 when opened, and the height is reduced. Small form. Therefore, even if there is a hanging cabinet or the like above, it is possible to prevent the lid 36 from hitting the hanging cabinet or the like, and it is possible to avoid being obstructive.

On the other hand, in the closed state, the lid 36 is extended from the above-mentioned folded state to cover the opening on the upper surface of the washing tank 6, and the operating member 80 is operated in this state. , First locking members 67, 68,
The second locking member 73 can be engaged with the cleaning tank 6 to be locked, so that the lid 36 can be securely closed. Therefore, it is also possible to prevent the washing water from scattering due to the washing operation inside the washing tank 6.
6 can be more assured, and in this case
Since the lid 36 cannot be opened unless the operation of unlocking the lid 36 is performed, the opening of the lid 36 due to mischief of a child can be prevented as much as possible.

Further, the lid 36 in the closed state is more liable to be lifted at a portion farther from the pivot portion, that is, at the free end side. In contrast, in the case of this configuration, the lid 36 is located at the free end side. First locking members 67 and 68 are provided on both sides of the lid 38, and a second locking member 73 is provided at the front end of the front lid 38 which is the most free end. Is locked in the closed state,
The closed state of the lid 36 can be more effectively locked, and a more reliable effect can be obtained in preventing splashing of the washing water.

In addition, in the case of this configuration, the operating member 8
0 is integrated with the second locking member 73. As a result, the structure can be simplified and provided at a low cost.
Further, it is possible to prevent the occurrence of "play" which is often seen in the case where they are separate from each other, thereby preventing a malfunction of the operation.

Further, the first locking locking members 67 and 68 and the second locking locking member 73 are linked by a link mechanism 82. As a result, the first
It is not necessary to separately operate the locking locking members 67 and 68 and the second locking locking member 73, and the operability can be improved.

Further, a hinge member 41 for pivotally supporting the rear end of the rear cover 37 is rotatably attached to the rear side of the upper frame 8 of the washing tank 6. Lid 3
7 is detachably attached to the rear end. As a result, when the cover 36 becomes dirty, the cover 36 is removed and the cover 36 is removed.
This can be done in a single state, so that it can be easily and desirably cleaned.

In this case, the rear end of the rear cover 37 is provided with a cylindrical mounting portion 53 fitted to the support member 42 of the hinge member 41, and the hinge member 41 is in the fitted state. Is provided with an elastic claw 44 for holding. Thereby, the lid 3
6 can be installed and removed without the need for special tools,
It can be easily installed and removed.

In addition, the rear lid 37 and the front lid 38 are
In the closed state, the peripheral portion of the back surface and the upper frame 8 of the cleaning tank 6
And a packing 60 for water-sealing between the rear cover 37 and the front cover 38 integrally with either one of them. Thereby, the water sealing property in the closed state of the lid 36 can be further improved,
A more reliable effect can be obtained in preventing the washing water from scattering.

In this case, the packings 58 and 59 are
It is assumed that the packing 60 has the flexibility to be water-sealed with a weight of 6, and the packing 60 has the same flexibility. Thereby, the water sealing property in the closed state of the lid 36 can be further improved, and in this case, the water sealing can be performed only by closing the lid 36, and an operation of pressing the packings 58, 59 particularly strongly. Is not required, so the lid 36 can be locked
After closing 6, the operation can be performed simply by operating the operation member 80, and the operability can be improved.

Then, the handle portions 6 are provided on both sides of the front lid 38.
4 are formed to protrude. Thus, since the opening and closing operation can be performed while holding the lid 36 independently of the left and right, the opening and closing operability can be improved. Moreover, in this case, if the front cover 38 is lifted by putting a hand on the handle portion 64, the rear cover 37 is also lifted integrally with the front cover 38 as shown in FIG.
6 is raised like a single lid. If there is a water droplet on the upper surface of the lid 36, it flows as shown by an arrow in FIG. 12 and falls from the rear edge of the rear lid 37. After the water droplets on the upper surface of the lid 36 are dropped in this manner, the lid 36 can be folded and fully opened, so that the water droplets on the upper surface of the lid 36 can be prevented from falling into the cleaning tank 6 from the front during that time. It is possible to avoid that the dried dishes in the tank 6 are wetted.

Further, a plurality of small projections 65 or small recesses are formed on the upper surface of the handle 64. Thereby, the lid 36
The handle of opening and closing the handle is improved, and for example, even if a detergent is attached to the hand, it can be made difficult to slip, so that the lid 3
6 can be further improved in opening and closing operability. Moreover,
In this case, the plurality of small protrusions 65 or small recesses on the upper surface of the handle 64 are provided to the visually impaired user by the handle 6 of the lid 36.
4 can also be used to teach the position.

In addition, a cover opening / closing detecting means 93 for detecting opening / closing of the cover 36 and a lock detecting means 102 for detecting that the second locking member 73 has locked the cover 36 are provided. Thereby, since the operation can be controlled by detecting the opening / closing of the lid 36 and the lock of the closed state of the lid 36, safety in use can be secured, and splash of washing water can be prevented. A more reliable effect can be obtained. In particular, in this case, even if the lock detecting means 102 has a failure (it does not turn off), if there is no failure in the lid opening / closing detecting means 93, the function can effectively function and the operation can be controlled. As a result, safety in use and prevention of washing water scattering can be more reliably achieved.

The lid opening / closing detecting means 93 and the lock detecting means 102 are composed of magnets 94 and 77 and reed switches 95 and 103, respectively. It is assumed that the lock 36 in the closed state is detected. This eliminates the need to provide a hole or an opening for detection in the portion where these components are provided, so that they can be detected with good waterproofness. Moreover, in this case, since the positions of the lid opening / closing detecting means 93 and the lock detecting means 102 are separated from each other, the lid opening / closing detecting means 93 and the lock detecting means 102 can be deliberately operated by a child's mischief or the like, and can usually be restricted to only one side. Since it is difficult to operate both of them at the same time, it is possible to ensure safety against mischief or the like of a child and more surely prevent splashing of washing water.

The non-contact method for detecting the opening and closing of the lid 36 and the lock of the closed state of the lid 36 may be, for example, a magnet and a Hall element, or a light emitting element, in addition to a magnet and a reed switch. The light-emitting element and the light-receiving element may emit light emitted from the cleaning tank 6 side.
It is preferable that the light is reflected by the light receiving element 6 and received by the light receiving element because the cover 36 does not need electric wiring.

In this case, both the lid opening / closing detecting means 93 and the lock detecting means 102 are in the ON state (the state in which the closing of the lid 36 has been detected and the locking has been further detected, and "YES" in steps S3 and S6). The operation is executed under the condition of “YES”, and both are not in the ON state (both the unlocking and opening of the lid 36 are detected, or only one of them is detected, and step S
The operation is not executed under the condition of “3,“ NO ”in S6).

Further, the lid opening / closing detecting means 93 is in the off state and the lock detecting means 102 is in the on state (the lid 36).
Although the lock is not detected, the closing is not detected even though the lock is detected.
Under the condition “S”), an abnormality is notified and the operation is not executed. This is because there is usually no possibility that the closure of the lid 36 has not been detected even though the lock of the lid 36 has been detected, and in this case, a failure has occurred in the lid open / close detection means 93. This makes it possible to make a judgment, so that the operation is not continued with the lid opening / closing detecting means 93 having a failure, and the safety in use and the prevention of scattering of the washing water can be more reliably achieved.

After the operation is completed and before the operation is started again, the lid open / close detecting means 93 and the lock detecting means 102
Is never turned off (step S19,
Under the condition of "NO" in S6, when the start switch is operated, an abnormality is notified (step S14) and the operation is not executed. This is because the tableware is usually taken in and out after the operation is completed and before the operation is started again. In this case, since the lid 36 is opened at least once, the lid open / close detection means 93 and the lock detection Means 102 should be off at least once, otherwise failure of lid open / close detection means 93 and / or lock detection means 102 may occur and remain on. Because it is possible. By coping with such a situation, safety in use and prevention of scattering of washing water can be more reliably achieved.

[0098] In this case, the target of the judgment in steps S19 and S6 may be only the lid opening / closing detecting means 93, not both the lid opening / closing detecting means 93 and the lock detecting means 102.

Then, the rear lid 37 and the front lid 38 of the lid 36
The gutter 63 is formed by extending from either one of them. Thereby, even if water, especially sewage or juices when the upper surface of the lid 36 is used as a cooking table or the like intrudes from between the rear lid 37 and the front lid 38, it is removed by the gutter 63. By receiving it and dropping it from the open portions at both ends onto the upper frame 8, it can be prevented from adhering to the lower packing 60, and the deterioration of the packing 60 can be prevented. In this case, the packing 60 does not exist, and the cover 3 is not provided.
In the case of discharging steam during drying from the space between the rear lid 37 and the front lid 6, the above-mentioned sewage and juice can be prevented from dropping directly into the washing tank 6. In addition, it is possible to avoid that the dried dishes in the washing tank 6 are wetted.

In this case, the locking locking member only needs to be engaged with the cleaning tank 6 to lock the lid 36 in the closed state, and the first locking locking member 67, 6
8 or the second locking member 7
Alternatively, the rear cover 37 may be locked in a closed state.

FIGS. 20 to 24 show the second and third embodiments of the present invention.
The same parts as those in the embodiment are denoted by the same reference numerals, and description thereof will be omitted. Only different parts will be described.

[Second Embodiment] In a second embodiment shown in FIGS. 20 and 21, a hinge member 41 for pivotally supporting the lid 36 is provided.
The shaft 201 is formed separately from the above-described support 42 in place of the above-described shaft 43. Further, the shaft 201 is formed by a fixed shaft 202 and a movable shaft 203 shown in FIG. ing. Among them, the fixed shaft 202 is cylindrical and has, for example, two partition ribs 204 protruding from the inner peripheral surface toward the center.

On the other hand, the movable shaft 203 is
The main part 203a located inside is cylindrical,
The outer peripheral surface is in close contact with the distal end surface of the partition rib 204 of the fixed shaft 202 so as to be slidable in the circumferential direction. Further, for example, two wing-like ribs 2 are provided on the outer peripheral surface of the movable shaft 203.
The wing-shaped rib 205 is formed with a notch 206 at each end thereof.

Further, a valve body 207 is fitted in each of the notch portions 206 of the wing-shaped rib 205 so as to be slidable in the circumferential direction. In this case, a notch 210 is formed in each of the protrusions 209 at the clockwise end in this case. And the fixed shaft 20
2 and the wing-like rib 205 of the movable shaft 203
In particular, in the state shown in FIG. 21A, the space on the counterclockwise side of each of the wing-like ribs 205 is filled with a highly viscous fluid, for example, a silicon oil 211, thereby forming the damper mechanism 212. doing.

In addition, as shown in FIG.
A connecting portion 213 having a non-circular cross section is formed at one end portion of the movable shaft 203 protruding from the hinge member 4.
A non-circular connection hole 214 is formed in one support 42,
By fitting these, the support 42 and the movable shaft 20
3 is configured to rotate integrally. On the other end of the fixed shaft 202 on the opposite side, a convex portion 215 is formed. On the other hand, the bearing portion 48 has a small concave portion 217 connected to a semi-cylindrical concave portion 216. And the recess 2
A fixed shaft 202 is accommodated in a small recess 217 and a convex portion 215 is accommodated in a small concave portion 217 so that the fixed shaft 202 cannot be rotated.

The fixed shaft 202 housed in the concave portion 216
As in the case of the shaft 43 described above, the pressing plate 50 is pressed from above by a pressing plate 50, and the pressing plate 50 is fixed to the bearing portion 48 by screws 51.

With this configuration, when the lid 36 is closed, the movable member 203 of the shaft 201 is turned in the direction indicated by the arrow M in FIG. Move. Thus, depending on the rotation of the movable shaft 203 in this direction, the wing-like ribs 205 respectively engage with the projections 208 of the valve body 207 on the side not having the notch 210 to slide the valve body 207 in the same direction. At this time, the silicone oil 21 existing at the slide destination
1 moves to the space on the side opposite to the slide destination as shown by the arrow N, whereas the wing-like ribs 205 respectively
7 is engaged with the projection 208 on the side not having the notch 210, so that the notch 206 of the wing-like rib 205 is
08, the silicone oil 211 is not moved quickly, and as a result, the silicon oil 211 has a large resistance to the rotation of the movable shaft 203 in this direction, and the lid 36 is closed. It will be done slowly.

On the other hand, when the cover 36 is opened, the shaft 2
In 01, the movable shaft 203 rotates in the direction indicated by the arrow O in FIG. Thus, depending on the rotation of the movable shaft 203 in this direction, the wing-like ribs 205 respectively
Is engaged with the projection 209 on the side having the notch portion 210 to slide the valve body 207 in the same direction. At this time, the silicone oil 211 existing at the slide destination is indicated by an arrow P.
Move to the space on the side opposite to the slide destination as shown by, but in this case, the wing-like ribs 205 respectively
10, the notch 206 of the wing-like rib 205 and the notch 210 of the projection 209.
And the movement of the silicone oil 211 is quickly performed through these. As a result, the silicon oil 211 does not have a large resistance to the rotation of the movable shaft 203 in this direction, and the lid 36 is quickly opened.

Thus, in the case of this configuration, the closure of the lid 36 can be softened with a buffering action, and especially when the closure of the lid 36 is naturally performed by relying on the weight of the lid 36, the user can use his / her fingers. So that you don't feel painful. In addition, the above-mentioned damper mechanism 212 is provided only on one side of the two hinge members 41, and thereby it is possible to suppress the increase in cost as much as possible. It may be provided.

[Third Embodiment] In the third embodiment shown in FIGS. 22 to 24, a magnet 301 is attached to the engaging portion 68a of one of the first locking locking members 68, and the magnet 301 is cleaned. In the back surface of the step portion 14 of the upper frame 8 of the tank 6, with the lid 36 closed, the reed switch is set to a position where the magnet 301 approaches when the one first locking member 68 is pushed out. Attach 302 and with these
A first lock detecting unit 303 configured to detect that the first locking member 68 has locked the lid 36 is configured. The reed switch 302 is attached by an attachment plate 304, and the attachment plate 304 is attached to the inner side wall 1 of the upper frame 8.
5 is attached to a boss 305 protruding from an outer surface of the boss 5 by a screw 306.

In addition to the first lock detecting means 303, the lock detecting means 102 for detecting that the second locking member 73 has locked the lid 36 is the second lock detecting means. Means.

Further, in this case, the aforementioned steps S3, S
The judgment of opening / closing of the lid 36 performed in 6, S15 and S19 includes:
As shown in FIG. 23, both the reed switch 302 of the first lock detecting means 303 and the reed switch 103 of the second lock detecting means 102 are turned off (both unlocking of the lid 36 is detected. After that, it is determined whether or not both are turned on (both the locks of the lid 36 are detected).

FIG. 24 shows the contents of the interrupt processing that is performed as needed during the operation (main routine) of control device 108.
As shown in (1), the reed switch 302 and the reed switch 103 are inspected, and it is determined whether one of the reed switch 302 and the reed switch 103 is on and the other is off. Step T1
1) If not (NO), return to the main routine; if so (YES),
The process proceeds to step T2 and step T3.

In addition, although not shown, in this case, when either the reed switch 303 or the reed switch 103 is turned off during the operation of the dishwasher 5, the control device 108 immediately starts the operation. The operation of the dishwasher 5 is stopped.

In this way, both the locking of the lid 36 in the closed state by the first locking locking member 68 and the locking of the lid 36 in the closed state by the second locking locking member 73 are detected. Therefore, the operation can be controlled, and the safety in use can be ensured, and a more reliable effect can be obtained in preventing scattering of washing water. In particular, in this case, both lock detecting means 303 and 102
Even if one of them has a failure (does not turn off),
If there is no failure on the other hand, this functions effectively and the operation can be controlled, so that the safety in use and the prevention of the scattering of washing water can be ensured.

It is preferable that the light is reflected on the 8, 73 side and received by the light receiving element, since the cover 36 does not need electric wiring.

In this case, both the first and second lock detecting means 303 and 102 are in the ON state (the state in which the lock of the lid 36 has been detected and the step S3
The operation is performed on condition that “YES” is determined in S6),
Neither is in the ON state (the state in which both the unlocking of the lid 36 is detected, and “N” in steps S3 and S6)
O "), the operation is not executed.

Further, one of the reed switch 302 and the reed switch 103 is on and the other is off (the first and second lock detecting means 30).
Under the condition that one of the failures 3 and 102 has failed and “YES” in step T11), the abnormality is notified and the operation is not executed. This is because despite the locking operation of the lid 36,
This is because it is usually impossible that the lock is not detected, and in this case, it can be determined that one of the first and second lock detecting means 303 and 102 has failed. Therefore, it is ensured that the operation is not continued if one of the first and second lock detecting means 303 and 102 is out of order, and that the safety in use and the prevention of splashing of the washing water can be ensured.

After the operation is completed and before the operation is started again, the first and second lock detecting means 303 and 102 are provided.
Is never turned off (step S19,
Under the condition of "NO" in S6, when the start switch is operated, an abnormality is notified (step S14) and the operation is not executed. This is because the tableware is usually taken in and out after the operation is completed and before the operation is started again. In this case, since the lid 36 is opened at least once, the first and second lock detections are performed. Means 30
3, 102 should be turned off at least once, otherwise the first and second lock detection means 3
This is because it is conceivable that a failure occurs in at least one of 03 and 102 and that it remains on. By coping with such a situation, safety in use and prevention of scattering of washing water can be more reliably achieved.

The present invention is not limited to the embodiment described above and shown in the drawings, and the following modifications or extensions are possible. The lid 36 may have a right end or a left end that is pivotally supported and is opened horizontally. or,
Cabinet 1 may be for something other than a kitchen, and may not be for a system kitchen, but may be for a washing machine. The object to be washed may be other than tableware, for example, vegetables, fruits, etc., and the washing method is not limited to the fountain type. good. The lid opening / closing detecting means may use a microswitch.
