Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a control device for a rice cooker used in general households, and particularly relates to improvements in inspection during manufacturing and product descriptions during sales at stores.

Conventional technology Even in recent home rice cookers, microcomputers, etc. are built into the control section to automatically control the temperature that is most suitable for the cooking process, and to control the time from the start of cooking to when the rice is cooked. Many are equipped with program control or timers that can be set using a timer.

Problems to be solved by the invention The operation of such program control and timer is as follows.
Because there is always an element of waiting to move on to the next stage only after a certain period of time has passed, inspections during manufacturing can take a very long time, and it is difficult to explain the product's functions with actual operation at the store. It was difficult.

The present invention has been made to solve these problems, and provides a rice cooker control device that can significantly shorten the inspection time during manufacturing and also allows product explanations based on actual operations at stores. The purpose is to

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention comprises a time reference signal section including a pulse generation means, a reference signal generation means, and a signal selection means, and a plurality of time reference 3 parts. h-> This allows signals to be given to other control units.

Effects With the above-described configuration, the present invention performs program control and timer operation at a regular time during normal operation, and performs program control and timer operation at a time earlier than the regular time during manufacturing inspections and product explanations at stores. This allows us to significantly shorten the inspection time during manufacturing, as well as explain the product through actual operation at the store.In other words, we can set a timer and actually operate the entire process from the timer operation to rice cooking. By doing so, it becomes possible to explain the product.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. FIG. 1 shows a functional block diagram of a control device for a rice cooker according to an embodiment of the present invention. In FIG. 3 is a pulse generating means for generating a pulse train of a predetermined period; 4 is a reference signal generating means for counting this pulse train and outputting a time reference signal; 6 is either this reference signal or the pulse train. A signal selection means selects one and outputs it to the rice cooking means 1 and the timer means 2.The signal selection means 6 selects the signal output from the reference signal generation means 4 during normal times, and outputs the signal from the reference signal generation means 4 during inspection or product explanation at the store. At this time, the output of the pulse generating means 3 is selected and the above-mentioned time reduction operation is performed.

FIG. 2 is a block diagram showing the overall configuration of a rice cooker using the control device shown in FIG. 1. In FIG. Reference signal generating means 4. The configuration of the signal selection means 6 is realized as a program. 11 is a heating device consisting of a heater and an actuator; 12 is a rice cooking container; 13
14 is a temperature sensor that indirectly detects the temperature of rice and water in the rice cooking container 12, 14 is a key switch such as start, stop, hour, minute keys, etc., and 16 is a display that displays each operation of rice cooking and timer. be. When a start signal is input to the rice cooking means 16b2 by the key switch 14,
The output signal of the signal selection means 6 is inputted, and the amount of heating of the rice cooking container 12 is program-controlled by the temperature sensor 13 and the heating device 11 while managing the time of each process. When the timer time is set and start is instructed by the key switch 14, the timer means 2 inputs the output signal of the signal selection means 5, subtracts the timer time, and when a predetermined value is reached, the timer means A start signal is given to end the timer operation. The display 16 displays the timer time, timer mode, rice cooking mode, etc.

As described above, since both the rice cooking means 1 and the timer means 2 perform timed operations (proceeding to the next step after a predetermined time elapses) based on the output signal of the signal selection means 5, the reference signal generation means 40 By changing the count number, that is, the number of pulses of the pulse generating means 3, it is possible to set the time ratio between normal operation and inspection to an arbitrary value.

In addition, in the case of a configuration in which the count number of the reference signal generating means 4 is changed between the rice cooking time and the timer time, the above-mentioned time ratio 66-zu can also be changed between the rice cooking time and the timer time.

Effects of the Invention As described above, according to the present invention, the rice cooking means and Since a signal selection means for outputting to the timer means is provided, the operating time can be greatly shortened during inspection during manufacturing or when explaining products at a store. In addition, in this case, the period of the applied signal is simply increased, but the time setting value is not changed, so inspection during manufacturing can be performed under conditions close to normal program operation.
This makes it possible to significantly increase the detection rate of defects during manufacturing.
