JPS6050482A - Timer apparatus of rice cooker - Google Patents

Abstract

PURPOSE:To improve handiness and to attain to eliminate inconvenience cooking unplatable rice, by inputting operation desired time as it is, and disabling the setting of subscribed time exceeding a predetermined time range. CONSTITUTION:A clock apparatus 3 outputs present time and a subscribed time input apparatus 2 sets the rice cooking start time or rice cooking finish time of a rice cooker. A subscribed time display apparatus 1 displays the subscribed time of the appartus 2 and a time comparing apparatus 4 compares the present time of the apparatus 3 and the subscribed time of the apparatus 2. An operator apparatus 5 operates time difference from the output of the apparatus 4 to display the same by the apparatus 1 only within a predetermined time range. Therefore, handiness is improved and inconvenience, such that rice spoils because of excessive water content or unplatable rice is cooked, can be eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a timer device for a rice cooker used in general households.

Conventional structure and its problems Conventionally, in the timer device of this type of rice cooker, the electronic type 1
Regardless of the mechanical type, it is common to start cooking rice a predetermined time after a set time.

However, with this configuration, it is necessary to calculate and set the time by subtracting the current time from the desired time to start cooking rice, and the calculation is complicated.

Also, some audio and video equipment allow you to set a recent reservation time, but this can be set without any restrictions as long as the time is within - weeks. If it is kept for too long, it will not solve the problem of rice becoming overly hydrated and spoiling.

OBJECTS OF THE INVENTION The present invention solves these conventional problems and provides a timer device for a rice cooker that is easy to use and can avoid misuse.

Composition of the Invention The rice cooker timer device of the present invention includes a clock device that outputs the current time, a reserved time input device that sets the rice cooking start time or rice cooking end time of the rice cooker, and a reserved time display that displays the reserved time. A time comparison device that compares the current time of the clock device with a reserved time, and an arithmetic device that calculates the difference between these times and displays it on the reserved time display device only within a predetermined time range. If there is no need to calculate the difference between the desired rice-cooking start time or rice-cooking end time and the current time, and if there is a timer mark that exceeds the rice's allowable submergence time, display this. Misuse can be avoided.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, numeral 1 is a scheduled time display device that displays the current time and rice cooking start time (reserved time), and displays other than the display regarding the time display the rice cooking status and functions. 2 is a reservation time input device for setting a reservation time. 6 is a "set" switch provided on the reservation time input device 2. When the "J" switch 6 is pressed, the time reserved in the past is displayed on the display device 1. 7 displays the "hour" of the time. 8 is a switch that displays the minutes of the time. By pressing the "set" switch 6 and then the "hour" switch 7 or "minute" switch 8, each digit of the reserved time display device 1 can be changed, and a new reserved time can be entered and set. can.

The power source of the reservation time display device 1 and the reservation time input device can be obtained from a battery or by rectifying and stepping down an AC power source. It goes without saying that the current time is set using a current time cent switch (not shown).

Next, in FIG. 2, parts with the same numbers as in FIG. 1 are the same devices. A three-digit clock device constantly measures the current time. Reference numeral 4 denotes a time comparison device that compares the current time measured by the clock device 3 with the reserved time set by the reserved time input device 2. Reference numeral 6 is an arithmetic device which selects the time closest to the current time as the reservation time if the time compared by the time comparison device 4 exceeds 12 hours (the time is determined by the permissible soaking time of rice and there is a degree of freedom in design). It is configured to be displayed on a display device 1.

For example, if the current time is rPM3:OOJ and rPM7:
If you want OOJ to start cooking rice, use the reserved time input device 2.
After pressing the “Set” switch 6, press the “Hour” switch 7.
, the "minute" switch 8 can be pressed the required number of times (in this case, the "hour" switch 4 times) to set l'-PM7:OOJ. However, if you try to set rAM7:OOJ for 16 hours, which is more than 12 hours from PM3:OOJ, you will have to press the "hour" switch 7 16 times, but 13
When the number is pressed, the time comparison device 4 and the calculation device 5 are
A comparison calculation is made to determine that the setting exceeds 2 hours, and the original "PM3:oo'J" is displayed on the reservation time display device 1.
M? : Informs that ooJ cannot make a reservation.

As above, when pressed for the 12th time, rAM3:ooJ
is displayed, and at the 13th time, the original jPMs:o
Since "2M4:oO" is displayed for the 14th time after oJ is displayed, it can be seen at a glance that the reservation cannot be set.

Although not shown, the reserved time is stored in a storage device, and is output when it coincides with the current time to operate the rice cooker.

Effects of the Invention As is clear from the above embodiments, the rice cooker timer device of the present invention is easy to use because the time at which the rice cooker is to be operated at a desired time can be entered as is, and it is easy to operate within a predetermined time range. Since it is not possible to set a reservation time beyond the specified time, it is possible to prevent mistakes such as excessive water content in the rice, spoilage of the rice, or cooking of unpalatable rice.

In addition, if you want to set the rice cooking end time to a desired time, the rice cooker measures the time required for the temperature of the rice cooking container to rise to a predetermined temperature and detects the amount of rice and water in the rice cooking container. This can be achieved by taking other means such as providing a detection device and a calculation device that determine the required rice cooking time and subtract the required rice cooking time from the desired rice cooking end time to start the rice cooking.
