JPH01319796A - Sound volume setting device for annunciating means - Google Patents

Abstract

PURPOSE:To decrease the number of components and reduce the area of a panel by operating switches including a setting switch specially and switching the setting switch and its display device to sound volume setting mode. CONSTITUTION:While the process select switch 1b of an input device 1 is pressed, the power source of an electric washing machine is turned on. When the power source is turned on, it is decided whether a switch 1b for process selection is on or off and a sound volume setting mode is entered when the switch is on. Consequently, the switch 1b functions as an input switch for sound volume setting and an LED 3a of the display device for displaying the state of process selection displays set sound volume. Every time the switch 1b is pressed, the setting of the sound volume of an annuciation device 5 is changed and three LEDs 3a illuminate in order matching large, intermediate, or small sound volume. Here when a start switch 1a is pressed, the sound volume setting mode is reset and a normal mode is entered, so that the switch 1b serves as the switch for selecting a process to display the process of the LEDs 3a.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a volume setting device for a notification means such as an end-of-operation notification buzzer of a home electric appliance that is electronically controlled by a microcomputer or the like.

2. Description of the Related Art A case in which a conventional sound volume setting device for a notification means is used in an electric washing machine will be described with reference to FIG.

In FIG. 4, 1a to 1e are various setting switches for setting the operation of the equipment, and 3a to 3d are the setting switches 1b.
This is a display means composed of a group of LEDs that indicate the setting states of 1e to 1e.

In this configuration, when setting the volume of the notification means for notifying when the device is shut down, the switch 1e for setting the buzzer volume is pressed. In response to this input, L of the display means 3d is displayed.
The ED lights up according to the set volume. The user sets the volume of the notification means while checking this display.

Problems to be Solved by the Invention However, in such a configuration, a dedicated display means 3d and a setting switch 1e are required to set the volume of the notification means, and there is a problem in that the number of parts and the display space increase, resulting in an increase in cost. there were.

In view of the above problems, the present invention aims to reduce the number of parts and display space.

Means for Solving the Problems In order to achieve the above object, the present invention provides a notification means for notifying the end of the operation of a device, a volume adjustment means for controlling the volume of the notification means, and a device for setting the operation of the device. and a display means for displaying the state of the setting, and by special operation of the switch including the setting switch, the setting switch can be switched to the volume setting of the notification means, and the display means can change the volume. This configuration displays the settings.

Effects According to the above configuration, when a switch such as a setting switch is specially operated, the setting switch is switched to volume setting and the display means of the setting switch is also used for volume display, so that a dedicated input is required for the volume setting of the notification means. The set volume can be input and set while confirming the set volume without providing any means or display means.

EXAMPLE 1 An example of the present invention will be described below with reference to FIGS. 1 to 3. This embodiment is an example in which the volume setting device of the notification means of the present invention is used in an electric washing machine.

In the figure, 1 is an input means composed of various setting switches 1a to 1d such as water flow, washing time, process selection, etc.; 2 is a control means that performs various controls based on the settings;
Reference numeral 3 indicates a display means composed of an LED for displaying various settings of the washing machine; 4 indicates a volume adjustment means controlled by the control means 2; and 6 indicates a notification means such as a buzzer for notifying the end of the operation of the washing machine. It is.

In this configuration, when setting the volume of the notification means 5, the washing machine is turned on with the process selection switch 1b of the input means 1 being pushed down. When the power is turned on, switch 1b for process selection is turned ○N as shown in Figure 3.
10FF is determined in step 12, and if it is ON, the volume setting mode is entered in step 13. Thereby, the switch 1b for process selection functions as an input switch for setting the volume, and the L of the display means 3 for displaying the status of process selection.
ED3a displays the set volume. Then, each time the process selection switch 1b is pressed, the volume setting of the notification means 6 is changed to make the volume louder.

Three LEDs, L E D 3 A, for medium and small sizes.
lights up sequentially. At this time, when the start switch 1a is pressed in step 17, the volume setting mode is canceled and the normal mode is returned, and the process selection switch 1a is pressed.
b functions as an input for selecting a process, and the LED 3a functions as a process display.

Effects of the Invention As is clear from the embodiments described above, according to the present invention, the setting switch and its display means can be switched for volume setting by special operation of the switch, and a separate setting switch or a separate setting switch for volume setting can be used. There is no need to provide a display means, and the number of parts and panel area can be reduced, leading to cost reductions.
