2. Description of the Related Art Generally, in a rice cooker equipped with a time display panel, the current time is normally displayed. However, when the cooked time is reserved, the reserved time is fixedly displayed and is kept warm. The heat insulation elapsed time was fixedly displayed. However, when the reserved time and heat retention elapsed time are fixedly displayed on the time display panel in this way, the current time is not displayed even though the time display function is provided.
It was inconvenient for the user who wanted to know the current time. Therefore, conventionally, either one of the reserved time and the current time is fixedly displayed during the reservation, and if the user presses a specific operation switch, the other is temporarily displayed only during the period when the operation switch is pressed. A rice cooker has been put into practical use, which displays the current time only during a period when a specific operation switch is pressed, by displaying the current time, while normally displaying the heat retention elapsed time.

Next, an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows a configuration of a control device 1 for a rice cooker according to the present invention and an arrangement of an operation panel 2 and a display panel 3. The control device 1 includes a central processing unit (CPU) 4, a clock unit 5 that measures the current time, a heat retention elapsed time timer unit 6 that measures the elapsed time from the start of heat retention, and a read-only memory that stores programs and the like. It is composed of a (ROM) 7 and a read / write memory (RAM) 8. The RAM 8 includes a reserved time storage unit 8a that stores the cooked time instructed by the user, a heat retention display mode storage unit 8b that stores either the current time or the heat retention elapsed time during heat retention,
It has a reserved display mode storage section 8c for storing which of the current time or the reserved cooked time is displayed during reservation or during reserved rice cooking.

The operation panel 2 and the display panel 3 are integrally provided on the front surface of the rice cooker. The operation panel 2 consists of multiple touch switches, and the rice cooking / reheating key 9,
It comprises a heat retention / cancellation key 10, a sleep heat retention key 11, a menu key 12, a reservation key 13, an hour / minute key 14 and a clock key 15. The clock key 15 constitutes the operating means of the present invention. The display panel 3 is a liquid crystal display board (LCD).
As shown in FIG. 2, it is used in which the time display, the type of rice cooked, the rice cooked heat insulation state display, etc. are written.

Next, the operation of the display processing by the control device will be described with reference to the flowchart of FIG. First, in step 101, it is determined what the current rice cooking mode is. If the rice cooking mode is "heat retention", it is determined in step 102 whether the heat retention display flag is 1 or 0. The heat retention display flag is stored in the heat retention display mode storage unit 8b of the RAM 8. If the heat retention display flag is 1, the current time is called from the clock unit 5 in step 103, and
The current time is displayed on the display panel 3 as shown in FIG.
The current heat retention elapsed time is called from and the heat retention elapsed time is displayed on the display panel 3 as shown in FIG. Then, in step 105, it is determined whether or not the clock key 15 is pressed, and if it is pressed, the heat retention display flag is inverted in step 106 and the flag is stored in the heat retention display mode storage section 8b. Returning to step 101, if not pressed, the process directly returns to step 101.

If the rice cooking mode is "reserved" or "reserved rice cooked" in the judgment of step 101, step 1
At 07, it is determined whether the reserved display flag is 1 or 0. The reserved display flag is stored in the reserved display mode storage unit 8 of the RAM 8.
c. If the reservation display flag is 1, the current time is called from the clock unit 5 in step 108, and
Display the current time on the display panel 3 as shown in (A),
If it is 0, in step 109, the cooked time is called from the reserved time storage unit 8a of the RAM 8 and the cooked time is displayed on the display panel 3 as shown in FIG. 5 (B). Then, in step 110, it is determined whether or not the clock key 15 is pressed, and if it is pressed, the reserved display flag is inverted and the process returns to step 101. If it is not pressed, the process directly returns to step 101. It should be noted that if it is determined in step 101 that the mode is other than "warm", "reserving", or "reserving cooked rice", the above display processing is not performed, and even if the clock key 15 is pressed, it is not accepted.

According to the display processing described above, while the temperature is kept warm, as shown in FIG.
When the current time in (A) is displayed, clock key 15
By operating, the heat retention display flag is inverted from 1 to 0, the heat retention elapsed time of FIG. 4B is displayed, and the display is held unless the clock key 15 is pressed. If the clock key 15 is operated while the current time shown in FIG.
From 0 to 0, the cooked time in FIG. 5B is displayed, and the display is held unless the clock key 15 is pressed. As described above, once the clock key 15 is operated to display the display convenient for the user, the display is always held, and when the user wants to see another display, the clock key 15 can be pressed or the original display can be displayed. When the display is desired, the clock key 15 may be pressed again.

In the above embodiment, the current time or the cooked time can be displayed in any of the "reserving" and "reserving cooked" modes. However, especially in the case of "reserved cooked" Instead of the cooked time, the remaining time until cooked may be displayed as shown in FIG.

[0014]

As is apparent from the above description, according to the first aspect of the invention, the current time or other rice cooking information is displayed on the display means according to the selection operation by the user, and until the next operation is performed. The state is continuously displayed. Therefore,
A user who uses the time display panel as a clock can always display the current time with priority, and can operate other operating means only when necessary to know other rice cooking information. For a user who does not need, it is possible to display the contents suitable for a wide variety of requests from the user, such as being able to always display the rice cooking information.

According to the second invention, the display contents can be independently switched and displayed for each process, and can be continuously displayed until the next operation, so that, for example, during reservation or during reserved rice cooking. The cooking time or remaining time is prioritized to be displayed, and the current time is prioritized and displayed in other processes during heat retention, so that it is possible to keep the display content according to the user's intention in each process. The number of times the user performs the display switching operation is reduced, and the complexity is avoided.
