Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine having an effective function when an infant falls into a washing tub.

[0002]

2. Description of the Related Art Conventionally, in a washing machine, in particular, a so-called fully automatic type washing machine, when a lid is opened during dewatering during a series of washing and dewatering steps, the dewatering tank is rotated at a high speed. Since there is a risk of the user touching the hands, the brake is suddenly actuated at the same time when the lid is opened, and the rotation of the dehydration tank is immediately stopped.

On the other hand, at the time of washing (washing and rinsing), the dehydration tub is not in a state of being rotated at a high speed, and the stirring body rotating in the washing tub also rotates at a relatively low speed, and the stirring body is generally used. Since it is located at the bottom of the washing tub, which is difficult for humans to reach, it is judged that there is no danger, and even if the lid is opened, the brake is not activated and the operation can be continued.

[0004]

However, even at the time of washing when it is determined that there is no danger as described above, for example, when a table or the like is accidentally placed near the washing machine, It is conceivable that the infant falls into the washing tub while opening the lid and looking into the washing tub. At this time, during washing, since water is usually accumulated in the washing tub, an infant falling in the washing tub may drown.

Even if water is not accumulated in the washing tub before the operation is started, water is supplied to the washing tub when the operation is started, so that an infant who has fallen into the washing tub is the same. There is a possibility of drooling, and further, the rotation of the stirring body may hurt the infant falling in the washing tub.

The present invention has been made in view of the above circumstances, and therefore an object thereof is to provide a washing machine capable of ensuring safety when an infant falls into a washing tub. .

[0007]

According to a first aspect of the present invention, there is provided a washing machine, a washing tub, a lid for opening and closing a doorway for loading and unloading laundry with respect to the washing tub, and detection of opening and closing of the lid. A lid opening / closing detection means and a water supply means for supplying water to the inside of the washing tub are provided, and when the opening of the lid is detected after the start of operation, the water supply means is not operated and further operation is performed. It is characterized in that a control means for controlling the progress is provided.

According to the above construction, since water is not supplied from the beginning, there is no possibility that an infant falling in the washing tub will drown. Further, since the stirring body is not rotated, there is no possibility that an infant falling in the washing tub will be damaged by the stirring body.

According to a second aspect of the present invention, there is provided a washing machine, a washing tub, a lid for opening and closing a doorway for putting laundry in and out of the washing tub, and a lid opening / closing detecting means for detecting opening / closing of the lid. A water supply means for supplying water into the washing tub and a water level detection means for detecting the water level in the washing tub, and when the opening of the lid is detected after the start of operation, the water supply means is It is characterized in that a control means is provided which is operated until the water level in the washing tub reaches a predetermined low water level and stops the progress of further operation.

According to the above construction, since water is supplied only to a low water level, there is almost no possibility that an infant dropped in the washing tub will drown. Further, since the stirring body is not rotated, a baby dropped in the washing tub cannot be damaged by the stirring body.

In this case, a notification means is provided, and the control means operates the water supply means until the water level in the washing tub reaches a predetermined low water level, and when the operation is stopped further, the notification means is activated. It may be configured to operate (the invention of claim 3). According to the above configuration, it is possible to clearly inform the user that the lid is open.

Further, the control means may be configured to restart the operation when the closure of the lid is detected while the operation is stopped (the invention of claim 4).
According to the above configuration, when the abnormality response control for stopping the progress of the operation is performed, the operation can be restarted only by closing the lid.

Further, a predetermined switch is provided and the control means is restarted when the closure of the lid is detected in the situation where the progress of the operation is stopped and it is determined that the switch is specially operated. It is also a good configuration to be configured as described above (the invention of claim 5).

According to the above configuration, when the abnormality response control for stopping the progress of the operation is performed, the operation is restarted only when the user's intention to specially operate the predetermined switch in addition to closing the lid is acted. To be done.

BEST MODE FOR CARRYING OUT THE INVENTION A first embodiment of the present invention will be described below with reference to FIGS. First, FIG. 5 shows the overall structure of a so-called fully automatic type washing machine. A plurality of outer tubs 2 are provided in an outer box 1 (only one is shown).
It is elastically supported and arranged by the elastic suspension mechanism 3 mainly including the suspension rods.

An inner tub 4 is rotatably disposed in the outer tub 2. The inner tub 4 is a washing tub and a dewatering tub. For example, a dewatering hole 5 is provided around the uppermost part. An inner basket 6 having a large number of dehydration holes (not shown) is installed on the inner periphery of the peripheral side portion in a single row. Further, a stirring body 7 is rotatably disposed on the inner bottom portion of the inner tub 4, and a drive mechanism 8 for selectively rotatably driving the stirring body 7 and the inner tub 4 during washing and dehydration is provided. , Is attached to the outer bottom of the outer tub 2.

The drive mechanism 8 is, for example, a motor 9 in detail.
And a belt transmission mechanism 10 for transmitting the rotational power thereof, a clutch 11 for switching the transmitted rotational power of the motor 9 between washing and dehydration, and the brake device 1
It has a housing 13 in which most of 2 and a gear reduction mechanism (not shown) are installed, so that the agitator 7 can be rotated in normal and reverse directions during washing, and the inner tub 4 can be rotated in one direction at high speed during dehydration. Has become. The stirrer 7 generates a washing water flow in the inner tub 4 by its rotation, and the inner tub 4 performs centrifugal dewatering of the laundry by its rotation.

Further, a drainage channel 14 for draining water from the inner vessel 4 is provided at the inner bottom of the outer vessel 2, and the inner tank 4 ( A drain valve 15 functioning as a drain means for discharging the water in the washing tub) is attached, and a drain hose 16 is connected to the drain valve 15.

An air trap 17 is formed at the tip of the drainage channel 14 and functions as a water level detecting means for detecting the water level in the outer tub 2 and the inner tub 4 via an air tube 18. The water level sensor 19 is connected. The water level sensor 19 also functions as water presence / absence detecting means for detecting the presence / absence of water in the inner tub 4, as will be described later, and is provided in the top cover 20 mounted on the uppermost part of the outer box 1. In addition, inside the top cover 20, a water supply device 22 mainly including a water supply valve 21 that functions as a water supply means for supplying water into the inner tub 4, and a control device 23 that functions as a control means and that includes a microcomputer, for example, are provided. It is arranged.

Further, the top cover 20 has an entrance / exit 24 through which laundry (not shown) is put in and taken out of the inner tub 4.
And a lid 25 that is, for example, folded in half, is provided to open and close the entrance 24, and inside the top cover 4,
A lid switch 26 that functions as a lid opening / closing detection unit that detects opening / closing of the lid 25 is also provided. The lid switch 26 is, for example, a micro switch that is turned on and off by an operation lever 27 that moves integrally with the opening and closing of the lid 25, as shown by the chain double-dashed line in FIG. It is designed to detect the opening and closing of.

Here, FIG. 6 shows an operation panel 28 provided on the front upper surface of the top cover 20. The operation panel 28 has a predetermined switch, ie, a “start / pause” switch 29, a “stroke” selection switch 30, a “course” selection switch 31, and a “water level” selection switch. 32, and a "safety" switch 33 that functions as an abnormality response control selection switch as well as a predetermined switch, and a display section 34 showing the selection contents of "stroke" and selection of "course". A display unit 35 showing the contents, a display unit 36 showing the selection contents of the "water level", a lamp 37 functioning as a display unit or a notification unit for displaying the abnormality response control setting, and a "detergent amount".
There is a display unit 38 that displays the required amount of.

FIG. 7 shows an electric circuit configuration of the washing machine. Between power lines 40 and 41 derived from a plug 39 inserted and connected to an outlet of a commercial power source (not shown),
The forward rotation triac 42, the reverse rotation triac 43, and the motor 9 of the drive mechanism 8 are connected in series. The motor 9 is composed of a single-phase induction motor having a main coil 9a, an auxiliary coil 9b and an external phase advancing capacitor 9c. For this motor 9, triac 42,
By selectively controlling the on / off of the motor 43, the motor 9
Can be energized in the forward rotation direction or in the reverse rotation direction.

A triac 44 and the water supply valve 21 are connected in series between the power supply lines 40 and 41,
Therefore, the water supply valve 21 is connected and disconnected by the triac 44. Further, a triac 45 and the drain valve 15 are connected in series between the power supply lines 40 and 41. Therefore, the drain valve 15 is electrically connected and disconnected by the triac 45.

A power switch 47 is inserted and connected on the side opposite to the plug 39 (on the side of the motor 9 and the water supply valve 21) of the connection point 46 of the one power line 41 to which the drain valve 15 is connected. The motor 9 and the water supply valve 21 are energized when the power switch 47 is turned on, and the drain valve 15 is energized regardless of whether the power switch 47 is on or off. The power switch 47 itself is provided on the operation panel 28 (not shown in FIG. 6).

Further, a constant voltage circuit 48 is connected between the power supply lines 40 and 41. The constant voltage circuit 48 converts an AC voltage into a DC constant voltage, and supplies the DC constant voltage to the control device 23. Here, the control device 23 has a function of controlling the overall operation of the washing machine, and stores a control program therefor in an internal memory. In addition, the control device 23 also has a non-volatile memory such as an EEPROM as another storage means (not shown).

The control device 23 receives various switch signals from a switch input section 49 including various switches 29 to 33 of the operation panel 28, and also receives detection signals from the water level sensor 19, and further, A detection signal is input from the lid switch 26, and on / off of each of the triacs 42 to 45 is controlled via the drive circuit 50 based on the input and the stored control program described above, and the operation is performed. Panel 2
It is configured to control the display operation of the display unit 51 including the various display units 34 to 36 and 38 and the lamp 37 of FIG. 8, and further to control the ringing operation of the buzzer 52 that functions as a notification unit.

Next, the operation of the above structure will be described. When the plug 39 is plugged into the power outlet and connected, the control device 23 is supplied with a constant DC voltage from the constant voltage circuit 48 and enters a standby state. When the power switch 47 is turned on in this state, first, as shown in FIG. 1, it is determined whether or not there is a mode setting operation (step S1). In this case, the determination of the mode setting operation is to determine whether or not the "safety" switch (abnormality response control selection switch) 33 has been operated, and the "safety" switch 33 has been operated. If (YES),
The lamp 37 is energized to continuously emit light, thereby indicating that the mode setting (abnormality countermeasure control setting) has been made (step S2).

Next, it is judged whether or not the switch 29 for "start / pause" is operated (step S
3) If it is determined to be (YES), the operation is started, and the water supply valve 21 is first energized to be opened, thereby supplying the tap water into the inner tank 4 ( Step S4).

During water supply, it is judged from the detection signal of the water level sensor 19 whether or not the water level in the inner tank 4 has reached a predetermined water level, for example, a reset water level almost equal to the lower surface of the agitator 7. Then (step S5), this determination also determines whether or not there is water in the inner tank 4. For example, at this time, when the previous operation ends with washing and rinsing too much, and water remains, or when the user is manually supplying water, etc., the water in the inner tank 4 is above the reset water level. If so, it is determined that the reset water level has been reached (YES).

If it is determined in step S5 that the water level in the inner tank 4 has reached the reset water level (there is water in the inner tank 4), then the lid 25 is turned off by the detection signal from the lid switch 26. It is determined whether or not it is open (step S6). At this time, if it is determined that the lid 25 is not open (NO), water supply is continued (step S7), and the water level sensor 19
It is determined whether the water level in the inner tank 4 has reached the set water level based on the detection signal (step S8). Then, in step S8, while it is determined that the set water level has not been reached (NO), the process returns to step S6, but if it is determined that the set water level has been reached (YES), the water supply valve 21 is disconnected. Then, the water supply to the inner tank 4 is completed (step S9).

On the other hand, in step S6, the lid 2
If it is determined that 5 is open (YES), there is a possibility that an infant has fallen into the inner tank 4, and therefore abnormality response control is performed (step S10).

In the abnormality handling control, as shown in the abnormality handling control routine in FIG. 1, the buzzer 52 is first energized to make a sounding operation to give a notification (step A).
1) Next, it is determined whether or not a predetermined time of t seconds (for example, 2 seconds) has elapsed (step A2). In addition, the notification is
It may be performed by blinking the lamp 37. If it is determined that t seconds have passed (YES), in this case, the water supply valve 21 is turned off to stop the progress of the operation (step A3), and then the drain valve 15 is energized to be opened. By doing so, drainage for discharging the water in the inner tank 4 is performed (step A4).

From the detection signal of the water level sensor 19,
It is judged whether the drainage from the inner tank 4 is completed (step A5), and while it is judged not completed (NO), the process returns to step A4, but it is judged completed (YES). If so, the driving is terminated and the operation is terminated. Even if the operation is terminated in this way, the notification by buzzing the buzzer 52 or blinking the lamp 37 continues.

On the other hand, while it is determined in step A2 that t seconds have not elapsed (NO), it is determined from the detection signal of the lid switch 26 whether or not the lid 25 is closed (step A6). If it is determined that it is not closed (NO), the process returns to step A2, but if it is determined that it is closed (YES), the notification is stopped, the process proceeds to step S7, and water supply (operation) is restarted. .

After the water supply is completed, the controller 23 performs washing as shown in FIG. 2 (step S11). This wash is
The motor 9 is energized and started, and the stirring body 7 is rotated forward / reversely by this. After that, the detection signal from the lid switch 26 is used again to determine whether the lid 25 is open. Yes (step S12). In this case, the lid 25
If it is determined that is not opened (NO), it is determined whether or not the mode setting (abnormality countermeasure control setting) has been canceled so far (step S13). In this case, the release of this mode setting is done by the switch 3 for "safety".
3 and the switch 29 for "start / pause" are used as special operations for operating them at the same time, and the operation panel 28 is provided with a line display 53 showing their relationship (Fig. 6).

If it is determined in step S13 that the mode setting has not been released (NO), washing is continued (step S14), and then it is determined whether or not it is time to finish washing (step S15). ). Then, in step S15, while it is determined that the washing end time is not reached (NO), the process returns to step S12, but if it is determined that the washing end time is reached (YES), the motor 9 is disconnected. Then, the washing is completed (step S16).

On the other hand, in step S12, the lid 25
If it is determined that the child is open (YES), there is a possibility that an infant has fallen into the inner tank 4, and therefore abnormality response control is performed (step S17). This abnormality handling control has the contents shown in the previous abnormality handling control routine, and if it is determined that the lid 25 is closed (YES) in step A6 of this abnormality handling control routine, in this case, the step S1
If it is determined in step S13 that the mode setting has not been released (NO) in step 3, the process proceeds to step S14 to restart washing (operation).

After the washing is completed, the controller 23 performs rinsing as shown in FIG. 3 (step S18). From this rinsing to the end of rinsing (step S23) is the same as the above-mentioned washing (step S11) to the end of washing (step S16), and the operation content is that the drain valve 15 is first energized. The drainage for discharging the water in the inner tub 4 by opening it, and the water supply for supplying tap water into the inner tub 4 by energizing and opening the water supply valve 21 thereafter. After that, the motor 9 is energized and activated to cause the stirring body 7 to rotate forward / backward. During that time, if opening of the lid 25 is detected in step S19, abnormality response control is performed (step S24). .

This abnormality handling control is also the same as the contents shown in the above abnormality handling control routine, and the lid 25 is closed (YE in step A6 of this abnormality handling control routine).
If it is determined to be S), in this case, the process proceeds to step S20, and if it is determined in step S20 that the mode setting has not been released (NO), the process proceeds to step S21 to restart rinsing (operation).

After the rinsing is completed, the controller 23 performs dehydration as shown in FIG. 4 (step S25). The process from this dehydration to the end of dehydration (step S30) is the same as the above-mentioned washing (step S11) to the end of washing (step S16), and the operation content is that the first drain valve 15 is energized. The drainage valve 15 is opened to contain the drainage that drains the water in the inner tub 4, and then the motor 9 is energized to be activated with the drainage valve 15 left open, whereby the inner tub 4 is moved in one direction. When the opening of the lid 25 is detected in step S26 during that time,
Abnormality response control is performed (step S31).

This abnormality handling control is also the same as that shown in the abnormality handling control routine, and the lid 25 is closed at step A6 of this abnormality handling control routine (YE).
If it is determined to be S), in this case, the process proceeds to step S27, and if it is determined that the mode setting is not released (NO) in this step S27, the process proceeds to step S28 to restart the dehydration (operation). Then, in this case, after the dehydration is completed, the entire operation is completed.

In response to the above, in the previous step S1, the mode setting operation (operation of the "safety" switch 33)
If it is determined that there is no (NO), step S in FIG.
As shown by 32-35, it is judged whether or not the same "start / pause" switch 29 operation as in the previous step S3 has been performed, the same water supply as in step S4, and the same water level in the inner tank 4 as in step S8. Judgment whether or not the set water level has been reached,
And the same water supply as in step S8 is completed.

Therefore, in this case, it is judged whether the water level in the inner tank 4 has reached the reset water level (whether there is water in the inner tank 4) and the lid 25 is opened. Driving proceeds without judging whether or not there is.

Further, in this case, after the end of the water supply, the control device 23 performs the same washing as in step S11 (step S36) as shown in FIG. 2 and thereafter, the "safety" switch 33 similar to step S1. It is determined whether or not the operation has been performed (step S37). Therefore, if the "safety" switch 33 has been operated until then, it has been operated in step S37 (YE
S), the mode setting display similar to step S2 is displayed (step S38), and the process proceeds to step S12.

If the "safety" switch 33 has not been operated so far, step S3 is performed.
In step 7, it is determined that no operation has been performed (NO), it is determined whether or not the washing end time is the same as in step S15 (step S39), and the washing is ended in step S16 (step S40).

Then, the controller 23 performs the same rinsing as in step S18 as shown in FIG. 3 (step S4).
1) After that, similarly to the above, it is determined whether or not the "safety" switch 33 is operated similarly to step S1 (step S42). Therefore, also in this case, the "safety" switch 33 has
If the operation is performed, it is determined in step S42 that the operation has been performed (YES), the mode setting display similar to step 2 is displayed (step S43), and in this case, the process proceeds to step S19.

If the "safety" switch 33 has not been operated so far, step S4 is performed.
In 2, it is determined that no operation has been performed (NO), it is determined whether or not the rinsing end time is the same as in step S22 (step S44), and the rinsing end is similar to step S23 (step S45).

Further, as shown in FIG. 4, the controller 23 performs dehydration similar to step S25 (step S25).
46) After that, similarly to the above, it is determined whether or not the "safety" switch 33 is operated similarly to step S1 (step S47). Therefore, also in this case, the "safety" switch 33 has
If the operation is performed, it is determined in step S47 that the operation has been performed (YES), the mode setting display similar to step 2 is displayed (step S48), and in this case, the process proceeds to step S26.

If the "safety" switch 33 has not been operated until now, step S4 is performed.
In step 7, it is determined that no operation has been performed (NO), it is determined whether or not the time is the same as the dehydration end time similar to step S29 (step S49), and the rinse is ended similarly to step S30 (step S50), Complete all operations. Although illustration is omitted, when the lid 25 is opened at the time of dehydration, the brake device 12 is suddenly actuated to stop the rotation of the inner tank (dehydration tank) 4 immediately as in the conventional case. There is.

On the other hand, if it is determined in step S13 that the mode setting has been canceled (YES), the lamp 37
The display of the mode setting is erased by turning off the light to turn off the light (step S51), and then it is determined whether or not the operation of the "safety" switch 33 (mode setting operation) similar to step S1 is performed. (Step S52),
If it is determined that the operation has been performed (YES), the same mode setting display as in step S2 is displayed (step S5).
3) The process proceeds to step S14, but if it is determined that there is not (NO), the same washing as in step S14 is continued (step S54), and the process proceeds to step S37.

If it is determined in step S20 that the mode setting has been canceled (YES), step S5.
The display of the mode setting similar to 1 is erased (step S5
5) Then, it is judged whether or not there is an operation (mode setting operation) of the "safety" switch 33 similar to step S1 (step S56). If it is judged that the operation is performed (YES), step S2 The same mode setting is displayed (step S57), and the process proceeds to step S21, but if not (NO), the rinsing is continued similarly to step S21 (step S58), and step S4.
Go to 2.

Furthermore, if it is determined in step S27 that the mode setting has been canceled (YES), step S27.
51 The same mode setting display is erased (step S
59), it is judged whether or not there has been an operation (mode setting operation) of the "safety" switch 33 similar to step S1 (step S60), and there has been that operation (YES).
If it is determined that the same mode setting is displayed as in step S2 (step S61), the process proceeds to step S28.
If not (NO), dehydration is continued similarly to step S28 (step S62), and step S4 is performed.
Proceed to 7.

As described above, in the present configuration, when it is detected that water is present in the inner tank 4, when the opening of the lid 25 is detected, steps A4 and A of the abnormality handling control routine are performed.
As shown in FIG. 5, the drain valve 15 is actuated. In short, by detecting the opening of the lid 25, it is determined that the infant may have fallen into the inner tub 4, and as an abnormal response control against it, By operating the drain valve 15, water is drained from the inside of the inner tub 4, thereby eliminating the possibility that an infant fallen into the inner tub 4 will drown and ensure safety. .

Similarly, when it is detected that there is water in the inner tank 4, and when the opening of the lid 25 is detected, the buzzer 52 is activated as shown in step A1 of the abnormality handling control routine. Alternatively, the lamp 37 blinks to notify the user of the occurrence of an abnormality, so that the user can take action (for example, the user stops driving and scoops up the infant from the inner tank 4). Can be done quickly and ensure safety.

Further, while the operation is in progress, when the opening of the lid 25 is detected, the operation is stopped as shown in step A3 of the abnormality handling control routine. In this case, it is possible to eliminate the possibility that the infant who has fallen into the inner tub 4 will be drowned because the water supply is stopped. Further, in this case, if the stirring body 7 is rotating, the rotation of the stirring body 7 can be stopped, so that there is no possibility that the infant dropped in the inner tank 4 is damaged by the stirring body 7. It is possible to ensure the safety of each. In addition, the operation of these drain valves 15, the operation of the notification means,
Also, the stop of the progress of the operation may be performed only on the condition that the opening of the lid 25 is detected regardless of the presence or absence of water in the inner tank 4.

In addition, steps S1, S37 and S4
2, S47, S52, S56, S60,
The "safety" switch 33 is provided as an abnormality response control selection switch, and the "safety" switch 3 is provided.
3 was operated (there was a mode setting for abnormality response control)
When it is determined that the abnormality response control is set, the abnormality response control can be performed in a home with an infant, for example, and the lid 25 can be used in a household without the abnormality response control. Even if it is opened, the conventional operation in which the abnormality response control is not performed can be performed.

Further, when the lamp 37 is provided as the display means and the setting for the abnormality response control is set, step S2 is performed.
As indicated by S38, S43, S48, S53, S57, and S61, the lamp 37 is caused to emit light to display it, and the determination as to whether or not the abnormality response control has been set is made by this. You can do it just by looking at the display
It is possible to more reliably ensure safety at home with infants.

Further, as shown in step A2, the abnormality response control is performed when the lid 25 is continuously opened for a predetermined time of t seconds, whereby the lid 25 is simply opened. In order to cope with abnormalities, stop the progress of operation,
We try to avoid drainage. this is,
When part of the laundry in the inner tub 4 is taken out or when additional laundry is added, the time required to close the opened lid 25 is short (normally, for example, less than 2 seconds). This is because if the operation is stopped or the water is drained just by opening the lid 25, the washing cannot be performed satisfactorily, and this is to avoid it. The time (t seconds) determined in step A2 may be specifically less than 2 seconds or may be more than 2 seconds.

Further, in that case, the buzzer 52 is used as a notification means.
Alternatively, when the lamp 37 is provided and the opening of the lid 25 is detected, as shown in step A1, the notifying means is immediately activated, and then it is determined that the opening of the lid 25 has continued for a predetermined time of t seconds. At the same time, the progress of the operation is stopped and the drain valve 15 is operated.
As a result, the opening of the lid 25 can be immediately notified without waiting for a predetermined time, so that in the unlikely event of an abnormality, the user can be immediately notified of it and the safety can be ensured more reliably.

As a means for canceling the abnormality response control, a "safety" switch 33 and a "start / pause" switch are provided.
Switch 29 for use in steps S13, S20,
As shown in S27, when it is determined that the abnormality handling control canceling unit has canceled the abnormality handling control, the abnormality handling control is not performed. Accordingly, when the abnormality handling control is canceled and the above-described normal use is performed, it is possible to avoid performing the abnormality handling control, and the washing can be smoothly performed.

Such a function is also effective for a washing machine which does not have a mode setting function and can always carry out abnormality response control. Further, in this case, the "safety" switch 33 and the "start / pause" switch 29 exemplified as the abnormality handling control releasing means are shown.
Is a special operation that operates them at the same time, and it is not an operation that can be easily performed by an infant.Therefore, it is possible to prevent the abnormal response control from being released due to mischief of the infant, and to ensure safety. You can be more certain.

Further, as shown in step S5, after the operation is started, the abnormality response control is not performed until the water level in the inner tank 4 reaches a predetermined water level (for example, reset water level). It is often the case that the lid 25 is opened by putting laundry or detergent into the lid 25 shortly after the start of operation. This is because if the buzzer 52 sounds, the operation is stopped, or the drainage is further performed just by opening the lid 25, it will be noisy or the laundry cannot be satisfied satisfactorily. .

Moreover, in this case, by setting the judgment water level to the reset water level, even if an infant falls into the inner tank 4, the water level is low, so there is no possibility of drowning and safety can be secured. . Note that the determination target in this case may be determined not by the water level in the inner tank 4 but by the time (predetermined time) after operating the switch 29 for "start / pause", for example.

In contrast to the above, FIGS. 8 to 15 show the second to ninth embodiments of the present invention.
The same parts as those of the embodiment are designated by the same reference numerals and the description thereof will be omitted. Only different parts will be described.

[Second Embodiment] In the second embodiment shown in FIG. 8, the operation panel 28 is not provided with the "safety" switch 33 and the lamp 37, and the "water level" selection switch 32 and the "stroke" are selected. When the control device 23 determines whether or not there is a mode setting operation (abnormality response control setting operation) by using the selection switch 30 as a predetermined switch (steps S1, S37, S42, S47, S52, S).
56, S60), it is determined whether or not these special operations are performed simultaneously.

In this way, the operation for setting the abnormality response control by the special operation of the switch is not a simple operation, so that it is possible to prevent the operation due to the mischief of the infant or the error of the user, and it is related to the intention of the user. Therefore, it is possible to avoid the abnormality response control from being performed, and the washing can be smoothly performed.

The special operation of the predetermined switch in this case is to simultaneously operate the "safety" switch 33 and the "start / pause" switch 29, which are the same as the abnormality handling control releasing means. It may be. Any combination of the "safety" switch 33, the "start / pause" switch 29, and the "water level" selection switch 32 and the "stroke" selection switch 30 described above, The infants are so far apart from each other that they cannot be simultaneously operated with the fingers of one hand, which makes it possible to prevent the infants from mischievous operations more reliably.

[Third Embodiment] In the third embodiment shown in FIG. 9, the control device 23 performs steps A3 through A3 after step A1 of the abnormality handling control routine.
The process is advanced to A5, that is, when the opening of the lid 25 is detected, the progress of the operation is immediately stopped and the drain valve 15 is operated. With this, the safety can be more reliably ensured.

[Fourth Embodiment] In the fourth embodiment shown in FIG. 10, the control device 23 performs a series of washing operations after step S30, that is, in a mode setting (abnormality handling control setting). After the operation is completed, the mode setting is canceled (step S101). As a result, in households that normally operate without setting the mode and set the mode only when necessary, the user does not have to cancel the mode setting one by one, improving the ease of handling. You can

[Fifth Embodiment] In the fifth embodiment shown in FIG. 11, the control device 23 performs a series of washing operations after step S30, that is, in a mode setting (abnormality handling control setting). After the operation is completed, the mode setting is stored, particularly in a nonvolatile memory such as an EEPROM (step S201). As a result, in a home where a mode is always set and operated, it is not necessary to carry out the operation of the mode setting for each operation, and the handleability can be improved and the safety can be ensured more reliably. The storage of the mode setting is not limited to after the series of operations of the washing operation described above is completed, and may be performed in the middle thereof.

[Sixth Embodiment] In the sixth embodiment shown in FIG. 12, the control device 23 determines whether or not the "pause" switch 29 has been operated after step S5. (Step S301). Control device 23
At the step S301, "Start / Pause"
If it is determined that the power switch 29 has not been operated (NO), the process proceeds to step S6, but it has been operated (YES).
If it is determined that the opening of the lid 25 is not detected, the operation is stopped (step S302), and then,
It is judged whether or not the switch 29 for "start / pause" is operated (step S303), and if it is judged that it is operated, the process proceeds to step S7.

In this case, if it is determined in step S8 that the set water level has not been reached after step S7, the process returns to step S301. Also, after step S8 (during washing, rinsing, and dehydration), although not shown, the same determination as in step S301 is performed, and it is determined that the "start / pause" switch 29 has been operated. Then, steps similar to steps S302 and S303 are performed.

Therefore, in this case, "start /
When it is determined that the "pause" switch 29 is operated, the abnormality response control is not performed. This is when you take out some of the laundry in the inner tub 4,
The user normally operates the switch 29 for "start / pause" when additional charging is required, so that the buzzer can be opened by simply opening the lid 25 during normal use. This is because if 52 sounds, the operation is stopped, or the water is drained, it will be noisy and the washing cannot be performed satisfactorily.

[Seventh Embodiment] In the seventh embodiment shown in FIG. 13, the control device 23 controls the lid 2 after the step S3.
It is determined whether or not 5 is open (step S401). In this step S401, the lid 2
If it is determined that No. 5 is open (YES), the control device 23 repeats step S401, and thus stops the progress of further operation without opening the water supply valve 21.

According to this, after the start of the operation, the lid 25
Since the water is not supplied from the beginning when is open, it is possible to eliminate the possibility that an infant falling in the inner tank 4 will drown. Furthermore, since the stirring body 7 is not rotated,
It is possible to eliminate the possibility of the infant falling in the inner tank 4 being injured by the agitator 7 and ensuring safety.
Also in this case, the above-described function is also effective for a washing machine that does not have a mode setting function and can always perform abnormality response control. In this case, step S4
If it is determined in 01 that the lid 25 is not opened (NO), the process proceeds to step S4 to supply water.

[Eighth Embodiment] In the eighth embodiment shown in FIG. 14, the control device 23 determines whether or not the lid 25 is opened after step S3, similarly to the above. (Step S501). This step S5
If it is determined in 01 that the lid 25 is not opened (NO), the process proceeds to step S4, and after step S5,
The process proceeds to step S7 without passing through step S6.

On the other hand, in step S501, the lid 2
If it is determined that No. 5 is open (YES), the controller 23 supplies water in the same manner as in step S4 (step 50).
2) After that, it is determined whether or not the reset water level has been reached as in step S5 (step S503). If it is determined in step S503 that the reset water level has been reached, the progress of the operation similar to step A3 is stopped (step S504), and then the same notification as in step A1 is issued (step S505). Then, it is judged whether or not the lid 25 similar to step A6 is closed (step S50).
6) If it is determined that it is not closed (NO), the process returns to step S504, but if it is determined that it is closed (YES), the process proceeds to step S7.

That is, in the case of this one, water is supplied even after the opening of the lid 25 is detected after the start of the operation, but it is up to the reset water level which is a predetermined low water level, and beyond that. Since water is not supplied and the operation is stopped, it is possible to eliminate the possibility that an infant dropped in the inner tank 4 will drown.
Since it is not rotated, it is possible to prevent the infant falling in the inner tank 4 from being damaged by the agitator 7, and to ensure safety.

Also in this case, the above-mentioned function is also effective for a washing machine which does not have a mode setting function and can always carry out abnormality response control. Also, in this case,
Even up to the reset water level, the amount of water supplied to the inner tank 4 can be shortened by the time required to supply water up to the set water level later (step S8).

In addition, in this case, even if the lid 25 is opened (YES in step S501) or closed (NO in step S501), water is similarly supplied up to the reset water level (step S503). , S5). Of which
When water is supplied up to the reset water level with the lid 25 opened, a notification is given (step S5).
05), which allows the lid 25
It is possible to clearly inform the user that the door is open, it is possible to prevent the user from misunderstanding, and it is possible to more reliably ensure safety.

Further, in this case, when the closing of the lid 25 is detected (step S506) in the situation where the progress of the operation is stopped (step S504), the operation is restarted. Since it is possible to restart the operation and to continue the operation only by closing 25, it is possible to save the trouble of performing the operation from the beginning again.

[Ninth Embodiment] In the ninth embodiment shown in FIG. 15, the control device 23 is the same as the above-mentioned one.
Further, after the step S506, it is determined whether or not the restart operation is performed (S60).
1). In this case, the restart operation is performed by using the "safety" switch 33 and the "start / pause" switch 29, which are the same as those in the abnormality handling control setting means or the abnormality handling control releasing means described above. This is a special operation that is performed at the same time, and if it is determined in step S601 that the restart operation has not been performed (NO), step S601 is repeated, but it was performed (YES).
If it is determined, the process proceeds to step S7.

That is, in this device, the closing of the lid 25 is detected (step S506) when the driving is stopped (step S504), and the switch 33 and the switch 29 are specially operated. When it is determined that the restart operation has been performed (step S60
1) The operation is restarted, whereby the operation is restarted only when the user's intention to specially operate a predetermined switch is actuated, and the operation is restarted by, for example, the natural closing of the lid 25 due to vibration or the like. Since it can be prevented, the safety can be ensured more reliably.

Incidentally, the presence / absence of water in the inner tank 4 and the lid 2
The determination of open / close detection of 5 and the abnormality response control may be performed before the operation is started (before step S3), and may be performed even when the power switch 47 is off. In particular, in the latter case where the abnormality handling control is performed even when the power switch 47 is off, for example, the configuration of FIG. 7 in which the drain valve 15 is energized regardless of whether the power switch 47 is on or off functions effectively. Besides, the present invention is not limited to the embodiments described above and shown in the drawings, and may be appropriately modified and implemented with respect to the presence or absence of a dehydration function and the like without departing from the scope of the invention.
