The present invention relates to a gas cooker, in particular a cooker of the type that changes the thermal power for heating the cooking pot (hereinafter referred to as rice cooker) as the city pipe. Conventionally, as a cooking machine of this kind, it is known to control heating as in FIG.

This is a preliminary heating time (A), cooking cooking time (B) to make up the whole process of cooking rice at the time of steaming (C) again, while controlling the thermal power in each heating time and at the same time according to the cooking amount The allocation of time is to be adjusted.

By the way, this conventional heating in the steaming time (C) is heated by a constant fire extinguishing power, so in the case of large cooking, condensation water may be generated on the inner surface of the cooker, which impairs the taste of the rice. Done.

This is because water at the bottom of the pot is evaporated and diffused into the rice at the time of cooking completion, because the thermal power of moxibustion is insufficient, and the diffusion steam condenses on the inner surface of the pot.

The present invention is a cooker in which the heating after cooking heating is adjusted to such a small amount of cooking, and in order to prevent the remaining of condensed water during mass cooking, it is a task to make it evaporate completely in the moxibustion heating process. That is, the fire power switching means for switching the heating means into two stages of interactive power and extinguishing power, the moxibustion heating control means (1) for regulating the heating time of the moxibustion heating by the fire extinguishing power and the size of rice to cook And the judgment output determining means 3b for storing the trace judgment means 2, the output of the judgment means and the output stored in the storing means for determining any one of the above judgments, and Final heating that operates after the end of moxibustion heating only when the output from the discriminating means is equivalent to a large quantity of cooking, and regulates this operation time in a fixed short time. Control means (4), etc., and this final heating is a furnace by heating power of the heating means.

The amount of rice cooked by the small amount determination means 2 is judged until completion of cooking heating. In the case of large cooking, the final heating control means is operated by the output from this determination means. The means 3a waits until the end of moxibustion heating.

In the case where the output from the determination pull force determining means 3b has a considerable output for a large amount of rice cooked, the final heating control means 4 operates at the end of the steaming time, and the pot is heated with the interactive force only for a certain short time.

This final heating is a very short time heating by the large-capacity force, so that only the dew condensation water during the moxibustion heating evaporates so that no yellowing occurs.

When the output by the judging means has a judging output of a small amount of cooking, there is no final heating and the moxibustion is terminated as it is.

The present invention is the same as the above configuration, irrespective of the small and large amount of cooking, the residual moisture in the rice to be cooked after the end of the moxibustion heating becomes the optimum state, it is possible to prevent the deterioration of taste due to excessive residual moisture.

Hereinafter, an embodiment of the present invention will be described in detail with reference to Figs. 3-4. In this embodiment, as the cooking trace determination means 2, the operation state is brought into operation at the start of preliminary heating, and the output contact 22 thereof has passed the set time. The first thermostat 21 that is formed at the time and the first thermostat 23 for regulating the preliminary heating temperature to a constant temperature, the contact B (upper contact 23b) of the first thermostat, and the output contact 22. Is started by the And output, and when the set time (600 seconds) has elapsed, the second timer 24 in which the upper output contact 25 is formed and the upper output contact are connected in series and the temperature in the rice cooker A is cooked. It becomes a 2nd thermostat 26 etc. which detect the time point which reached the 1st preset temperature (115 degreeC) just before reaching completion temperature.

According to this determining means, the amount of rice is determined depending on whether the time required from the end of preheating until the first set temperature is longer or shorter than the set time of the second timer 24 is determined. Since the output contact 25 is closed when the set time has elapsed, the output corresponding to the mass cooking is obtained only when the cooker A does not reach 115 ° C at this time.

As the determination output storage means 3a, a self-holding relay R is employed and the output contact R ₁ is a parallel circuit between the third timer 41 and the relay R, which becomes the final heating control means 4. It is connected in series.

In addition, the output contact 42 of the third timer is connected in series with a parallel circuit of the first excitation coil 52 of the kettle side 51 and the second excitation coil 54 of the auxiliary electron side 53. When the set time of the timer 41 has elapsed, the output contact 42 is kept in a closed state for a predetermined time (10 seconds).

Therefore, the relationship between the conduction and non-conduction of the 1st excitation coil 52 of the main rotor edge 51 and the 2nd excitation coil 54 of the auxiliary solenoid 53 which control the burner 61 as a heating means is the last heating step. Is switched by the output contact 42 of the third timer 41, and the burner 61 becomes the interactive force only during the time when the output contact 42 is closed.

In addition, the heating control means (1) is a first closing timer (7), its switching output contact (71) (72), and the moxibustion thermostat (73). The contact is connected to the first excitation coil 53 side via the moxa thermostat 73 and the diode 55, and this circuit is connected in parallel with the third timer 41.

Therefore, during the set time of the 1st moxibustion heating timer 7, it heat-controls by the moxibustion thermostat 73 to a preset temperature (101 degreeC).

Moreover, the 1st moxibustion timer 7 is connected in series with the B contact (upper contact 82) of the 3rd thermostat 8 which detects the cooking heating end time, and the 1st moxibustion timer 7 is closed by this B contact. When the start time starts, the contact on the normal closing side of the switching output contact 71 is closed, and the circuit from the control circuit 20 to the first and second excitation coils 52 and 54 is cut off.

In addition, the first moxibustion timer 7 is self-holding by the upper contact of the switching output contact 71, and the switching output contact 72 on the other side is connected in series with the third timer 41, which determines the determination output. The third timer 41 is started at the end of moxibustion heating by means 3b.

In the above embodiment, as shown in FIG. 3, cooking is performed by varying the heating power and the temperature of the rice cooker. The above embodiment is based on the sequence control or can be controlled as shown in FIG. 4 using a microcomputer.

In this second embodiment, the point of time elapsed after the end of moxibustion heating is set to the completion point of cooking, and for this purpose, a second moxibustion timer is combined.
