Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a jar rice cooker having a demonstration mode.

Conventional technology In recent years, jar rice cookers have become more sophisticated and equipped with microprocessors (hereinafter referred to as microcomputers).
It is becoming more and more multifunctional. For this reason, function introductions and explanations on how to use them tend to be complicated and redundant, but conventional jar rice cookers do not have modes or functions similar to demonstrations, so introductions to their functions and explanations on how to use them tend to be complicated and redundant. I was going by letting it happen.

Problems to be Solved by the Invention In such a conventional jar rice cooker, each condition must be manually input to set the operating conditions. There are problems such as having to repeat the condition settings from the beginning, and because the timer operation and rice cooking operation are closely related to the required time, it is not possible to provide explanations that match the actual usage in a short period of time. Moreover, during the explanation of the rice cooking operation, the heater becomes energized and generates heat, which is dangerous.

The present invention solves these conventional problems, and aims to provide a jar rice cooker whose functions and handling methods can be easily and concisely explained.

Means for Solving the Problems In order to solve the above-mentioned problems, the jar rice cooker of the present invention includes a storage means that stores a demonstration procedure simulating a rice cooking operation, and a storage means for storing a demonstration process that simulates a rice cooking operation, Alternatively, the mode selection means for selecting whether to perform the demonstration, and the notification device that notifies the rice when the rice is cooked while keeping the heating device in a non-heating state when the demonstration is selected, are not activated and the rice cooking menu is sequentially changed. and a control means for continuously repeating the demonstration.

According to the above configuration, by selecting the demonstration using the mode selection means, the rice cooking menu can be automatically changed to repeat a motion that briefly imitates the operation of each rice cooking menu. , it is possible to introduce functions and explain operations in a concise manner. Furthermore, during the demonstration, the heating device is kept in a non-heating state and the notification device is not driven, so it is safe and quiet and can be continued for a long time without any problem.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings.

FIG. 1 is a functional block diagram of a jar rice cooker showing an embodiment of the present invention. In FIG. It stores the processing procedure of the timer process, rice cooking process, and heat retention process (hereinafter collectively referred to as the rice cooking sequence), and is connected to the control means 3. Reference numeral 2 denotes a second storage means, which stores a processing procedure that briefly simulates a rice cooking sequence, and is connected to the control means 3. Reference numeral 4 denotes mode selection means, which determines from which of the first storage means 1 or the second storage means 2 the control means 3 will read the processing procedure. 5 is a heating device, which is controlled by the control means 3; 6 is a notification device,
It is driven by control means 3.

Next, the operation of this embodiment will be explained using FIG. 2 showing a specific circuit diagram of this embodiment.

The control means 3 controls the output 4a of the mode selection means 4 to
If the output is Low, the processing procedure for the rice cooking operation is read out from the first storage means 1, and on the other hand, if the output of the mode selection means 4 is High, the processing procedure for the rice cooking operation is read out from the first storage means 1.
The processing procedure of the demonstration is read out from , and the rice cooking operation or the demonstration is executed according to the read processing procedure. The heating device 5 is
Transistor 11 driven by control means 3
It consists of a relay 13 whose contacts 13a are opened and closed by the transistor 11, a heater 14, and a relay power supply 12. Now, if a non-driving command for the transistor 11 is stored in the second storage means 2 in advance, the transistor 11 will not be driven in the demonstration, so the relay contact 1
3a remains off, and therefore the heater 14 is maintained in a non-energized state, so that it does not generate heat. Similarly, if a non-driving command is stored in the second storage means 2, the notifying means 6 will be non-driving and will not notify during the demonstration. 7, 8, 9 are LEDs,
The timer process, rice cooking process, and warming process are displayed respectively. 10 is a liquid crystal display element (LCD) that displays time and messages regarding rice cooking. Here, the first storage means 1 and the second storage means 2
The control means 3 is built into a one-chip microcomputer.

Figure 3 is a flowchart showing the process flow.
The flow of processing will be explained based on FIG. 3. At step 31, the setting of the mode selection means is determined, and if demonstration is selected, the process moves to the next step 33. In step 33, a process is executed to keep the heating device 5 in a non-heating state, and in step 34, a process is executed to make the notification device 6 non-alert. In step 35, the rice cooking menu is set, and in step 36, the time of the timer process and other initial settings are made, and the process moves to step 37. After repeating this loop of steps 37 and 38 a predetermined number of times, the timer step is completed and the process proceeds to the next step. The same goes for the next loop of the rice cooking process and the loop of the warming process. At this time, in the timer step 37, the rice cooking step 39, and the warming step 41, the LEDs 7, 8, and 9 are lit to display the steps, and a message is displayed on the LCD 10 as necessary. Now, steps 41 and 4
After going through the loop consisting of 2 a predetermined number of times, the process returns to step 35, the rice cooking menu is changed, and the above process is repeated. In this way, demonstrations imitating each rice cooking menu are continued indefinitely, and in this case, the heating device 5 is kept in a non-heating state and the notification device 6 is not driven.

Effects of the Invention As described above, according to the present invention, rice cooking operations and functions can be clearly demonstrated by executing a demonstration according to pre-stored processing procedures, and the handling is easy.
Moreover, it is possible to provide a safe jiyar rice cooker.
