JPS6396421A - Timer for gas cooking oven and the like - Google Patents

Abstract

PURPOSE:To make it possible to count time in second during a timer is in operation by providing a state of timer mode display section to show the state of mode of timer in a timer a for general household gas cooking oven, etc. CONSTITUTION:When either one of mode setting keys 11 and 13 for timer modes A and B is pressed down, a mode display lamp 12 or 14 for a timer is lighted to show that the timer has been set to a timer mode. Afterwards the timer starts with a time set by an hour setting key 15 and a minute setting key 16. Then the mode display lamp 12 or 14 starts flickering at a prescribed time interval and the counting of time in second of the timer is displayed. With this constitution it is possible to read visually the second counting of the timer.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a timer for general household gas stoves and the like.

Conventional technology A conventional gas stove will be explained.

FIG. 3 shows a block diagram of a conventional gas stove. In the figure, 1 is the stove burner, 17 is the ignition
Timer A of the stove burner 1, a manual cock for extinguishing the fire, is as follows. 19 is a timer interval display section, 6 is a buzzer notification section, 7 is a time setting means, and 18 is a microcomputer that controls the timer time display section 19 and the buzzer notification section 6, performs timer counting, etc. The timer A counts down from the time set by the time setting means 7.

Problems to be Solved by the Invention However, in the above configuration, although the timer time is displayed on the timer time display section 19, there is nothing to indicate whether or not a countdown is being performed during operation. The time display only changes every minute.

In view of the above-mentioned problems, the present invention provides a timer function of a gas stove by creating a display section to indicate that it is in timer mode, and adding a function to display the count of seconds during which the timer is operating on the display section. This product provides a gas stove for the purpose of

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention adds a function to the timer function to indicate that the device is in a timer mode.

EXAMPLE Hereinafter, a gas stove according to an example of the present invention will be described with reference to the drawings.

FIG. 1 shows a block diagram of a gas stove according to the present invention, and FIG. 2 is a configuration diagram showing an embodiment of a time display section and time setting means.

In FIG. 1, 1 is a stove burner, 2 is a motor-driven closure, 3 is a motor control circuit means for controlling the motor, 4 is a solenoid valve, and 5 is a solenoid valve control for controlling the opening and closing of the solenoid valve 4. A circuit means, 6 is a buzzer notification section, 7 is a timer setting means for setting a timer time, 8 is a time display section 8a and a display section 9 of a timer mode display section 8b is a microcomputer that controls the control circuit means and the display section. Al.

In FIGS. 2a and 2b, 10 is an LED of the time display part 8a in the display part 8, 11 is a setting key for timer mode A as the timer mode display part 8b in the display part 8, and 1
2 is a mode display lamp for the timer mode A. 1
3 is a setting key for timer mode B of the timer mode display section 8b, and 14 is a mode display lamp for the timer mode B.

15 is a time setting key, and 16 is a minute setting key.

First, when either the timer mode A or B setting key 11 or 13 is pressed, the mode indicator lamp 12 or 14 of the timer lights up to indicate that the timer mode has been entered. Thereafter, the timer starts operating at the time set using the hour setting key 15 and minute setting key 16. When the mode is activated, the mode display lamp 12 or 14 lights up for 0.5 seconds, and then goes to 0.
．． The light will start blinking for 5 seconds and the timer will display the seconds count.

As described above, the present invention provides a timer function of a gas stove with a function that lights up the timer mode indicator lamp in the timer mode state and flashes it simultaneously with the start of the timer operation to display the count of seconds. By adding this, the timer's second count can be visually checked, allowing the user to know at a glance that the timer is operating.
