Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooker using a microcomputer in a cooker such as a jar.

2. Description of the Related Art Conventionally, a cooker has been set by a timer device or the like until the start of energization, but especially in a jar type rice cooker (a cooker that cooks rice and keeps it warm for a long time). By setting the time until the cooking is completed, the cooking time can be estimated in advance and the power supply can be started.

However, in order to set the time to start energizing in anticipation of the cooking time in advance, the cooking has to be completed from the current time, and the time until the finished time has to be calculated, which is very troublesome. Therefore, a reservation timer device has been developed which can set a completion time to make a reservation at that time.

Problems to be Solved by the Invention Since the device has the above-described functions, it is necessary to remember the current time and the reserved time when starting to use the cooker. There was a problem that it became difficult to use it for the first time, and it became difficult to use it for the first time.

Means for Solving the Problems The present invention has been made to solve such problems, and it is possible to set a specific reserved time (for example, 6:00 am and 6:00 pm) that is generally used for a microcomputer. ) Are stored, and these reserved times are displayed on a plurality of reserved time display portions provided on the control panel.
Therefore, the user of this cooker can set the present time at the start of use of the cooker and remember it, and the reserved time when cooking is completed is remembered.

Action By doing the above, if you set the current time when you start using the cooker and remember it, the reserved time normally used when cooking is completed is automatically remembered and the reserved time display section Display a specific reservation time at. Therefore,
Usually, the reserved time is often enough, so there are few operations and it is easy to understand even when using for the first time.

Embodiment One embodiment of the present invention will be described below with reference to the drawings by taking a jar type rice cooker as an example.

FIG. 1 is a front view of a control panel (hereinafter, panel) P of a jar type rice cooker using a microcomputer.
The figure is also a functional block diagram showing the relationship between the respective means.

In the figure, reference numeral 1 is a current time display portion provided in the panel P, and by pressing the "hour" key 2 and the "minute" key 3 which are the current time setting means 5 in the microcomputer described later, "hour",
Setting or changing the "minute" and pressing the "end" key 4 which is the same means 5 completes the setting of the current time. The current time set by the current time setting means 5 is timed by a clock means 6 having a timekeeping function in a microcomputer (not shown) provided in the main body (not shown) of the jar type rice cooker, and the current time is displayed. It is to be displayed in part 1. Reference numerals 15 and 16 are reservation time display portions for displaying the reservation times stored in the reservation time storage means 8 provided in the microcomputer, respectively. When the clock means 6 starts operating, a specific reservation time, for example, the display portion 15 The reservation 1 is automatically set to 6:00 am, and the reservation 2 on the display unit 16 is set to 6:00 pm. The plurality of reserved times are input to the program of the microcomputer at the time of assembly at the factory and shipped.

9 is a "select" key which is provided in the panel P and is used to select the time when the time displayed on the current time display section 1 or the reserved time display sections 15 and 16 is to be corrected. Then, first, the current time display section 1 becomes a blinking display,
When the button is pressed continuously, the reserved time display section 15 blinks and the current time display section 1 returns to the original lighting display. When it is pressed continuously, the reserved time display section 16 returns and the current time display section 1 returns to the original time display section 1. It is designed to be repeated. Also the reservation time display
When 15 and 16 are blinking, you can correct the time with "hour" key 2 and "minute" key 3, and press "end" key 4 to correct the reservation time. The hour "select" key 9, the "hour" key 2, and the "minute" key 3 function as reserved time adjusting means 10 provided in the microcomputer, respectively.

11 and 12 are set buttons for setting a reservation timer (reservation start 1 and reservation start 2), which are arranged so as to correspond to the reservation time display portions 15 and 16, respectively.

The reserved time displayed on the reserved time display portions 15 and 16 is the time of completion of cooking, and when the set buttons 11 and 12 are pressed, they are preset and stored by the clock means 6 and the reserved time storage means 8. Compare the current time by subtracting the cooking time (for example, 45 minutes for normal white rice cooking),
When the current time coincides with the cooking start time, the comparison means 13 for starting the cooking execution completes the cooking at the reserved time. Reference numeral 14 is a cooking execution means, which starts energization of heating means such as a rice cooking heater (not shown), and is composed of, for example, a relay.

The current time setting means 5, the clock means 6, the reservation time automatic setting means 7, the reservation time storage means 8, and the reservation time correction means.
The 10 and the comparison means 13 are programmed, for example, in a microcomputer provided in the main body of the jar type rice cooker, and the cooking execution means 14 is provided in the main body and controls cooking in response to an instruction from the microcomputer. It is provided in the control unit (not shown).

 Next, the operation of this embodiment will be described.

First of all, when the plug of the cooking device is inserted into the outlet and power is turned on, 0:00 am flashes on the current time display section 1, so use the "hour" key 2 and "minute" key 3 to adjust to the current time.
When the "end" key 4 is pressed, the current time is set, the blinking display changes to a lighting display, and the clock means 6 starts operating.

At the same time, the reservation time automatic setting means 7 displays 6:00 am and 6:00 pm on the reservation time display portions 15 and 16, respectively, and the respective reservation times are stored.

To set so that cooking is completed at the reserved time, press the set button 11 or 12 beside the reserved time display portions 15 and 16 displayed respectively. Subtract the cooking time (45 minutes above) preset by the current time by the clock means 6 and the reserved time storage means 8 so that cooking is completed at the reserved time of the pressed set button 11 or 12 from the reserved time. The comparing means 13 for comparing with the current time compares the time that changes momentarily, and when the current time is the same time as the cooking start time, the comparing means 13 issues a cooking start instruction to the cooking executing means 14 to start cooking. To do.

Further, in order to change the reserved time for completion of cooking set in the microcomputer in advance, press the "select" key 9 to display the time of the current time display section 1 and the reserved time display section 15,
Reservation time to be changed out of 16 times, for example, if it is reservation 1, display section 15 blinks, and the displayed time is corrected with "hour" key 2 and "minute" key 3, and "end" key 4 is pressed. If pressed, the corrected time is set and stored in the reserved time storage means 8.

EFFECTS OF THE INVENTION As described above, in the cooker of the present invention, the reserved time is automatically set and displayed on the reserved time display section when the cooker is first used. There is no need to set it, and with a minimum of key operations, it is possible to provide a cooker of great value that anyone can easily start using immediately.
