Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a notification device for washing machines, dryers, and other devices, which notifies the status of the device by means of a melody.

2. Prior Art Conventionally, for example, to explain the notification of the end of washing by a washing machine, as shown in FIG. , melody information is outputted to the notification section 4 as appropriate, and a melody notification is made when washing is completed.

Problems to be Solved by the Invention In this conventional method, the melody information was written in the ROM 2 of the microcomputer 1 in advance and could not be rewritten. Therefore, if the melody is a melody that the user personally dislikes, the user feels uncomfortable. Also,
Even if you didn't dislike the melody, you would get tired of hearing the same melody every time.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to provide a notification device for equipment in which a melody can be rewritten.

Means for Solving the Problems In order to achieve the above object, the present invention provides a mode select switch that can switch between normal use of the device and melody setting, and a mode select switch that allows control of normal use and input of melody information by switching this switch. a melody notification unit that performs melody notification; a microcomputer that controls the operation of the melody notification unit by inputting melody information from the key input unit; and a backup unit that backs up the power supply of the microcomputer. It has a power supply section.

Effects According to the present invention, with the above configuration, control melody information for normal use can be input, and the melody information input by the user at the key input section can be secured in the microcomputer by the backup power supply, and the microcomputer can store the melody information input by the user at the key input section. Information can be broadcast via the melody broadcast section.

Embodiment Hereinafter, a washing machine of the present invention will be explained as an example.
In the figure, reference numeral 11 denotes a key input section for inputting melody information of the user's choice, and includes a shift switch 11a, an input switch 11b, a setting end switch 11c, and each key switch 11d.
Reference numeral 12 is a mode select switch, and a normal mode terminal 1 allows input of information such as washing machine water flow selection, washing time, spin-drying time, and washing pause.
3, and a setting mode terminal 14 that enables setting of melody information. Reference numeral 15 denotes a melody notification section that performs melody notification; 16 a microcomputer that inputs information from the key input section 11 and controls the melody notification section 15 and the washing machine; and 17 a backup power source that backs up the power supply of the microcomputer 16. Department. As shown in FIG. 2, the key input section 11 is installed at a location where the device 18 can be easily operated, and each key switch 11d controls the device during normal use.

Normally, the mode select switch 12 is connected to the normal mode terminal 13 side. In this state, the microcomputer 16 does not accept outputs from the shift switch 11a, input switch 11b, and setting end switch 11c, and each key switch 11
Only output from d is accepted. In other words, it receives the outputs of key switch SW1 which selects washing machine washing, key switch SW2 which sets washing time, switch SW3 which sets spin-drying time, and key switch SW4 which provides information on suspending washing, and controls based on the settings. It is no different from the operation in a conventional washing machine.

Next, when it is desired to set the melody, the mode select switch 12 is switched to the setting mode terminal 14 side. In this state, key switch SW1~
Switch SW4 to the scale "C" to "F", and while pressing shift switch 11a, switch key switch SW.
When SW1 to SW4 are pressed, data corresponding to "G" to "C" of the musical scale is input to the microcomputer 16. Use these key switches SW1 to SW4 to set the first note of a certain melody.
This sound data is then input to the microcomputer 16 by pressing the input switch 11b. Then, when the second tone is set and the input switch 11b is pressed, the data is input to the microcomputer 16 as data following the first tone. In this way, data for each note of the melody is input in order from the beginning. Then, after setting the last note and pressing input switch 11b,
Press the setting end switch 11c to end the melody setting. Then, set the mode select switch 12 to the normal mode terminal 13 side to put the washing machine in the normal operating state.

Even if the washing is finished and the power to the device is turned off, power continues to be supplied to the microcomputer 16 from the backup power supply section 17 for a certain period of time. Therefore, the melody information can always be stored in the microcomputer 16 regardless of whether or not power is applied. Therefore, at the end of the process of the washing machine, the microcomputer 16 controls the melody notification section 15 to output a melody based on the previously set melody information.

Note that the backup power supply section 17 can be constructed of, for example, a lithium battery, electric double layer capacitance, etc., but it is obvious that the same effect can be obtained with either of them.

Effects of the Invention According to the present invention, an arbitrary melody can be set as a notification melody using a key switch for controlling the device, and it can be rewritten as many times as desired, making it suitable for diversifying device notifications and suiting the user. It is possible to perform melody notifications. Furthermore, since the backup power supply allows the microcomputer to retain information, there is no need to write information every time the power is turned on, improving usability.
