BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine that activates a notification device and a display device when an abnormality occurs to notify the user of the abnormality.

0002

2. Description of the Related Art In recent years, washing machines have been provided that are equipped with an alarm device such as a buzzer and a display device such as a light emitting diode, both of which are activated when an abnormality occurs. This is because simply activating the alarm device when an abnormality occurs does not tell you what it is reporting.In order to assist with this, the display device blinks all the light emitting diodes or indicates an abnormality. It is designed to display abnormalities by displaying the contents as a code.

[Problem to be Solved by the Invention] However, when the notification device is activated, some users recklessly operate keys in order to stop it, and as a result, the operation of the display device is also stopped (erased), causing an abnormality. occurrence is not recognized,
Alternatively, the system may be reset without the details of the abnormality being recognized. As a result, even if the operation is restarted, the stoppage due to abnormality will be repeated, and furthermore,
With a device that remembers the previous operating mode and reproduces it when the power is turned on, there is a problem in that the operation mode is changed due to the above-mentioned careless key operation, and then it is set again the next time the power is turned on. was.

[0004] The present invention has been made in view of the above-mentioned circumstances, and therefore, its object is to operate a notification device and a display device to notify of an abnormality when an abnormality occurs.
To provide an excellent washing machine in which a display device does not stop operating or an operation mode is not changed even if a user performs a careless key operation when an abnormality occurs.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the washing machine of the present invention includes an operation input to stop the operation of the alarm device and an operation to cut off the power when the alarm device is operating when an abnormality occurs. The present invention is characterized in that it includes a control means that maintains the display device in an operating state without accepting any operation input other than the input.

[0006]

[Operation] According to the above means, even if the user makes unnecessary key operations when an abnormality occurs, when the alarm device is operating, other operation inputs other than the operation input to stop the operation of the alarm device and the operation input to cut off the power supply can be performed. Since the display device is kept in the operating state without accepting any operational input, the display device will not be stopped operating or the operating mode will not be changed. Also, in this case, since the operation input to stop the operation of the notification device is accepted, the operation of the notification device can be stopped arbitrarily, and since the operation input to cut off the power is also accepted, the reset is also optional. can be made to

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 the entire washing machine, in which a washing tub 2 and a dehydrating tub 3 are arranged side by side. Further, a washing lid 4 and a dehydrating lid 5 are provided on the upper surface of the outer box 1, and a panel 6 is also provided, and the panel 6 is provided with a power switch 7 and an operation/display section 8.

FIG. 3 shows a part of the operation/display section 8, which includes an operation key 9 for setting the water level, an operation key 10 for setting the water flow, and an operation key for setting the course. 11. Operation key 1 for setting washing time
2. Operation key 13 for setting the rinsing time, operation key 14 for setting the spin-drying time, operation key 15 for starting and stopping operation, setting and stopping the buzzer for sounding and non-sounding. In addition to operating keys 16, there are also light emitting diodes 17 to 22 and a digital display 23 serving as display devices for displaying the settings.

On the other hand, FIG. 4 shows a control device 24 consisting of a microcomputer installed on the back side of the panel 6, which is supplied with the necessary power from a power source 25 based on a household power outlet. It is now possible to do so. The control device 24 also includes an operation key 1 for the buzzer.
An operation signal is inputted from the power switch 6, and each operation signal is also inputted from the other operation keys 9 to 15, and an operation signal is also inputted from the power switch 7. Based on these inputs and a control program stored in advance, the control device 24 includes a drive circuit 26 that drives a buzzer 25, which is a notification device, and a display consisting of the light emitting diodes 17 to 22, a digital display 23, etc. A drive control signal is applied to a drive circuit 28 that drives the section 27, and a drive circuit 30 that drives a drive section 29 that includes a washing motor, a dewatering motor, a water supply valve, a drain valve, etc. (not shown), and is operated as described below. It functions as a control means.

The details of control by the control device 24 will be described below.

As shown in FIG. 1, the control device 24 first determines whether the power switch 7 has been turned on (step S1) when its operation is started, and when it is determined that the power switch 7 has been turned on, The display devices (display unit 27) such as the light emitting diodes 17 to 22 and the digital display 23 are operated in a standard state (step S2).

Next, the operation setting by the user is accepted (step S3), and then it is determined whether or not the start key has been operated (step S4). When it is determined that the start key has been operated, the drive unit 29 is activated to start operation according to the set contents (step S5).

After that, it is determined whether or not there is any abnormality (step S6), and if it is determined that there is an abnormality (NO), the operation is then stopped (step S7), and then,
Operation inputs other than the buzzer operation key 16 and the power switch 7 are not accepted (step S8), and
The display device is operated to display the abnormality, for example, by blinking all the light emitting diodes or displaying a code indicating the abnormality content on the digital display 23 (step S9).

Next, the buzzer 25 is sounded to notify that an abnormality has occurred (step S10), and then it is determined whether or not the power switch 7 has been turned off (step S11). If it is determined that the buzzer operation key 16 has been operated (step S12), then it is determined whether or not the buzzer operation key 16 has been operated (YES).
If it is determined that the operation will not be performed, wait for 15 seconds to pass (step S13).
, the buzzer 25 stops sounding (step S14).

[0016] After the buzzer 25 has stopped sounding in this way, the state returns to the state where all operation inputs are accepted (step S15), and in this state, the next operation is to stop (erase) the operation of the display device. It is determined whether or not there is an input (step S16), and the operation input is determined (Y
ES), the operation of the display device is stopped (step S17).

Note that if it is determined in step S11 that the power switch 7 has been turned off (YES), the process jumps to step S17 and the operation of the display device is stopped.

[0018] Also, there is no abnormality in the previous step S6 (YE
If it is determined that the operation end time has been reached (step S18), then it is determined whether or not the operation end time has been reached (step S18).
When the answer is YES), the operation is stopped (step S19), and as in step S8, operation inputs other than the buzzer operation key 16 and the power switch 7 are not accepted (step S20). S1
0, the buzzer 25 sounds, and in this case, the end of the operation is notified. Thereafter, steps S11 to S17 are as described above.

As described above, in this configuration, when the buzzer 25 is sounding when an abnormality occurs (the notification device is in operation), the operation input from the operation key 16 (operation input to stop the buzzer 25 sounding) and the power switch are activated. Since the display device is controlled to remain in operation by not accepting any other operation inputs other than the operation input from 7 (operation input to cut off the power supply), the user can not hear the buzzer 25 sound when an abnormality occurs. Even if a key is operated inadvertently other than the normal operation input to stop the operation, the display device will not stop operating or the operation mode will not be changed, and the occurrence of an abnormality or the details of the abnormality can be recognized as reliably as possible. As a result, it is possible to eliminate problems such as repeated stoppages due to abnormalities when restarting operation, and undesired operation modes being re-set when the power is turned on next time.

Furthermore, in this case, since the regular operation input to stop the sound of the buzzer 25 is accepted, it is possible to stop the sound of the buzzer 25 at will, and furthermore, the operation input to cut off the power is also accepted. Because of this, the reset can be done arbitrarily without causing any practical inconvenience.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings, but may be modified without departing from the scope of the invention, particularly regarding the specific parts and configurations of the notification device and display device. It can be implemented with appropriate changes.

Effects of the Invention As is clear from the above description, the washing machine of the present invention is equipped with an alarm device and a display device, and is configured to operate them when an abnormality occurs. The display device is characterized by comprising a control means that maintains the display device in the operating state by not accepting any other operation inputs other than the operation input to stop the operation of the notification device and the operation input to cut off the power supply while the notification device is in operation. As a result, even if the user makes unnecessary key operations when an abnormality occurs,
Problems where the display device does not stop operating or the operation mode is not changed, and when restarting the operation, it repeatedly stops due to an error, or the undesired operation mode is set again when the power is turned on next time. In addition, it is possible to stop the operation of the notification device at will, and furthermore, it can be reset at will, which is an excellent effect.
