BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine equipped with an illumination lamp for illuminating the inside of a washing tub.

[0002]

2. Description of the Related Art Conventionally, in a washing machine, it has been considered to illuminate the inside of a washing tub with an illumination lamp so that the laundry can be easily taken in and out even in a dark place or in the dark. ing.

[0003]

However, even in the case considered as described above, the illumination of the inside of the washing tub by the illumination lamp and the elimination of the illumination are generally performed by operating the switch for the illumination. However, there is a problem that the operation is troublesome because the operation has to be done one by one. Further, in this case, if the switch operation for erasing the illumination is forgotten, the illumination lamp remains lit, which consumes a lot of power unnecessarily.

On the other hand, it is considered that the illumination lamp is turned on and off according to the opening and closing of the lid above the washing tub. With this product, it is not necessary to operate the switch inside and out in order to turn off the lighting inside the washing tub and that lighting. Also, if the lid is closed, the lighting lamp goes off, so another switch operation is required. Not doing so does not consume a lot of power in vain.

However, in this case, when the lid is closed,
At the same time, the lighting lamp goes out, so immediately after that, if you want to check the inside of the washing tub, such as whether the operation started normally, you need to open the lid again and turn on the lighting lamp. Was troublesome.

The present invention has been made in view of the above circumstances, and therefore an object thereof is to illuminate the inside of a washing tub with an illumination lamp and to erase the illumination without requiring a separate switch operation. Another object of the present invention is to provide a washing machine in which wasteful consumption of electric power can be avoided as much as possible, and furthermore, the state inside the washing tub immediately after the lid is closed can be checked without opening the lid one by one.

[0007]

In order to achieve the above object, the washing machine of the present invention comprises an illumination lamp for illuminating the inside of the washing tub, wherein the lid above the washing tub has a washing tub. With a see-through part for seeing through the inside of the
A lid opening / closing detecting means for detecting opening / closing of the lid is provided, and the illumination lamp is turned on when it is determined from the detection result that the lid is opened, and after a predetermined time has elapsed when it is determined that the lid is closed. It is characterized in that the lighting lamp is controlled to be turned off.

In addition, the washing machine of the present invention comprises an illumination lamp for illuminating the inside of the washing tub, which is provided with a lid opening / closing detecting means for detecting the opening / closing of the lid above the washing tub, and the illumination. There is a lighting mode setting means for setting a mode with and without lighting, and when the mode with lighting is set by the setting means, the lighting lamp is turned on according to opening and closing of the lid, and the mode without lighting is set. In this case, the lighting lamp is turned off regardless of whether the lid is opened or closed.

Further, the washing machine of the present invention comprises an illumination lamp for illuminating the inside of the washing tub, and is provided with a lid opening / closing detecting means for detecting the opening / closing of the lid above the washing tub. A time determination means for determining the time is provided, and when it is determined from the result of the determination that the current time is within a predetermined time period, the lighting lamp is turned on in response to opening and closing of the lid, and the time is other than the predetermined time period. When the determination is made, the lighting lamp is controlled to be turned off regardless of whether the lid is opened or closed.

[0010]

According to the above means, the illumination lamp can be turned on and off basically according to the opening and closing of the lid above the washing tub, and no additional switch operation is required.

In addition, when the lid is closed, the illumination lamp is controlled to be turned off after the predetermined time has elapsed. After the lid is closed, the illumination lamp continues to light up to illuminate the inside of the washing tub. While inside, the situation inside the washing tub can be confirmed through the transparent portion of the lid.

In addition, it is unnecessary for the user to provide the illumination mode setting means for keeping the illumination lamp off regardless of whether the lid is opened or closed when the mode without illumination is set by the illumination mode setting means. It is possible to avoid turning on the illumination lamp in the situation determined to be.

Further, a time determination means for determining the current time is provided, and when the current time is determined to be outside the predetermined time zone from the result of the determination, the illumination lamp is kept turned off regardless of whether the lid is opened or closed. In this case, it is possible to avoid lighting the illumination lamp in an unnecessary time zone such as daytime.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. First, FIG. 2 shows an outer box 1 of a washing machine, in particular, a so-called fully automatic washing machine, in which a washing tub 2 also serving as a dehydrating tub is arranged. A top cover 3 is attached to the uppermost part of the outer box 1, and a laundry entrance / exit 4 is formed in the center of the top cover 3, an operation panel 5 is provided in the front part, and an illumination lamp 6 is provided in the rear part. Are provided respectively. The operation panel 5 has a key switch 7 which functions as a lighting mode setting means for setting a mode with or without lighting by the lighting lamp 6, while the lighting lamp 6 has a washing tub 2
The interior of the washing tub 2 is illuminated by the lighting. Further, the top cover 3 is pivotally provided with a lid 8 for opening and closing the laundry entrance / exit 4, and the lid 8 is provided with a see-through portion 9 for seeing through the inside of the washing tub 2.

On the other hand, FIG. 3 shows a control device 10 including a microcomputer, which functions as a time determination means for determining the current time because it has a clock function, and also the illumination lamp 6 It functions as a control means for controlling as described later.

A lid open / close detection signal is input to the control device 10 from a lid switch 11 which functions as a lid open / close detection means for detecting the opening / closing of the lid 8, and the key switch 7 of the operation panel 5 is also inputted. Various switch signals are input from a switch input unit 12 including various switches, and a water level detection signal is input from a water level sensor 13 that detects the water level in the washing tub 2.

Further, based on those inputs and a control program stored in advance, the control device 10 drives the illumination lamp 6, the display section 14 including various displays of the operation panel 5, and the buzzer 15. Drive circuit 1
A motor 17 for giving a drive control signal to 6 and rotating the washing tub (dehydration tub) 2 and an agitator in the washing tub 2.
And a water supply valve 18 for supplying water into the washing tub 2 and the washing tub 2
A drive control signal is also given to a drive circuit 20 that drives a drain valve 19 that drains water from the inside.

Therefore, the contents of control based on the function of the control device 10, particularly for turning on and off the illumination lamp 6, will be described below. As shown in FIG. 1, the control device 10 sets the current time to a predetermined time zone, for example, from 7:00 to 17:00 at the beginning of the control operation (interruption routine) for turning on and off the illumination lamp 6. It is determined whether it is within the daytime time zone (step S1). Here, if it is determined that it is within that time zone, the mode setting with illumination is set (step S2), and if it is determined to be outside the time zone, mode setting without illumination is performed (step S2).
3).

After that, it is judged whether or not the lid 8 is opened from the closed state (step S4),
If it is determined by the detection signal from the lid switch 11 that the lid 8 is opened from the closed state, then it is determined whether or not the mode with illumination is set (step S5). Here, if it is determined by the result of step S2 or the switch signal from the key switch 7 that the mode with illumination is set, the illumination lamp 6 is energized and turned on (step S6). Therefore,
Thereby, the inside of the washing tub 2 is illuminated, and then the control device 10 determines whether or not the lid 8 is closed (step S7).

If it is determined in step S7 that the lid 8 is not closed by the detection signal from the lid switch 11, the controller 10 starts counting by the timer (step S8), and then the counting result. From this, it is judged whether or not a predetermined time t1 has passed (step S
9). This predetermined time t1 is, for example, 5 minutes at which it can be judged that the lid 8 has been forgotten to be closed, and if it is judged that the predetermined time t1 has passed, the illumination lamp 6 is turned off and turned off (step S10). Therefore, as a result, the lighting inside the washing tub 2 is stopped, and then the control device 10
Clears the timer (step S11) and returns to the main routine. After that, if the lid 8 is left unclosed, it is determined that the lid 8 is not opened from the closed state in step S4 of the interrupt routine thereafter, and the process proceeds to the next step. First, only when the lid 8 is closed and then opened, the step S4 is performed.
Then, it is judged that the lid 8 is opened from the closed state and the process proceeds to the next step.

On the other hand, in step S9, the predetermined time t1
If it is determined that the time has not passed, the process returns to step S7,
In this returned step S7, if it is determined by the detection signal from the lid switch 11 that the lid 8 is closed, the timer is cleared (step S12), and then the timer starts counting (step S13). From the count result, it is determined whether or not a predetermined time t2 has passed (step S14). This predetermined time t2 is, for example, 1 to 2 minutes which is judged to be necessary for checking the internal condition of the washing tub 2 after the lid 8 is closed, and until the predetermined time t2 is judged to have passed. Since the control device 10 keeps lighting the illumination lamp 6 and continues to illuminate the inside of the washing tub 2, the inside of the washing tub 2 can be seen through the see-through portion of the lid 8 even after the lid 8 is closed. You can check the situation. If it is determined in step S14 that the predetermined time t2 has elapsed, the process proceeds to step S10 to turn off the illumination lamp 6 and turn it off.

In step S14, the predetermined time t2
While it is determined that the lid 8 has not been opened, it is then determined whether or not the lid 8 has been opened (step S15), and when it is determined that the lid 8 has not been opened, step S13.
Return to and continue counting by the timer. If it is determined that the lid 8 has been opened, the timer is cleared (step S16), and then the process returns to step S5 to determine whether or not the mode with illumination is set.

Further, if it is determined in step S5 that the mode with illumination is not set (the mode without illumination is set), the process proceeds to step S10 and the illumination lamp 6 is turned off and turned off. Keep in a state.

As described above, in this structure, the illumination lamp 6 can be turned on and off basically according to the opening and closing of the lid 8 above the washing tub 2, and another switch operation is required. Since it does not, the operation can be simplified. Further, in this case, since the illumination lamp 6 is turned off only by closing the lid 8, it is possible to prevent wasteful consumption of a large amount of power even if another switch is not operated.

Further, in addition to this, when the lid 8 is closed, the illumination lamp 6 is controlled to be turned off after a predetermined time has passed, so that the illumination lamp 6 is turned on after the lid 8 is closed. While the interior of the washing tub 2 is continuously illuminated, the state of the inside of the washing tub 2 can be confirmed by seeing through the see-through portion 9 of the lid 8.
The troublesome operation of turning on can be saved.

In addition, the illumination mode can be set by the user, and when the mode without illumination is set, the illumination lamp 6 is kept turned off regardless of whether the lid 8 is opened or closed. It is possible to avoid lighting the illumination lamp 6 in a situation where the user determines that it is unnecessary, and it is possible to further suppress wasteful power consumption.

Further, with the function of judging the current time,
When it is determined from the result of the determination that the current time is outside the predetermined time period, the illumination lamp 6 is open regardless of whether the lid 8 is opened or closed.
By keeping the switch off, it is possible to avoid lighting of the illumination lamp 6 in an unnecessary time zone such as daytime, and this can also suppress wasteful consumption of electric power.

The present invention is not limited to the embodiment described above and shown in the drawings, and one of them is as follows.
The brightness of the illumination by the illumination lamp 6 may be changed, and the key switch for setting the illumination mode may be used in combination with other switches without departing from the gist. Can be appropriately changed and implemented.
