Is steamed into the container to steam the glutinous rice in the container, and the drive motor is energized to rotate the blades that are the kneading tools to knead the glutinous rice in the steamed container to a certain degree. I try to lift the rice cake after hours. In addition, a safety device such as a temperature fuse or thermostat is attached to the drive motor, and if the drive motor overheats for some reason, the safety device operates and the power to the drive motor is forcibly cut off. I am trying to do it.

However, the food cooking machine having such a structure is
If the drive motor continues to overheat due to a malfunction of the temperature fuse or thermostat, the cooker body made of synthetic resin, which is particularly thermally weak, is easily deformed or melted due to ignition from the drive motor. May occur. Further, in order to deal with such a problem, there is a method of forming the cooking machine main body entirely of metal, but the outer shape is limited to a simple box shape, which causes a problem of poor design.

Therefore, in view of the above problems, the present invention does not deteriorate the design of the cooking machine body and affects the peripheral portion of the cooking machine body even if the drive motor continues to overheat. Its purpose is to provide such a food cooking machine.

In the case of making glutinous rice, after containing a predetermined amount of water in the boiler 16, water and sticky rice are stored in the dipping container 8 and the dipping container 8 is inserted into the upper portion of the boiler 16. After arranging, the bottom of the dipping container 8 is dipped in the water in the boiler 16. When the immersion switch (not shown) on the operation panel 37 is turned on, the heater 31 starts to be energized and the boiler 31
The water temperature in 16 rises and the periphery of the bottom of the dipping container 8 warms. Then, the glutinous rice contained in the dipping container 8 is heated together with the dipping water, and the submersion of the glutinous rice increases depending on the temperature. After that, the heater 31 is turned off to keep the water temperature in the boiler 16 constant, so that the inside of the dipping container 8 is kept at the optimum temperature for dipping, and the whole glutinous rice swells uniformly and moderately. In this way, the immersion is completed after a lapse of a predetermined time, and the power interruption to the heater 31 is automatically terminated.

After the dipping is completed, the dipping container 8 is removed from the cooking machine body 1, and the dipping container 8 is used as it is to drain the glutinous rice. Then, instead of the dipping container 8, the container 7 is seated on the upper part of the boiler 16, and the shaft 21

When the steaming switch (not shown) of the operation panel 37 is turned on, the heater 31 starts to be energized and the water contained in the boiler 16 evaporates. The steam evaporated from the boiler 16 passes through fine holes (not shown) formed in the bottom of the container 7 to steam the glutinous rice in the container 7.

After the glutinous rice has been steamed, the operation panel 37
When a kneading switch (not shown) is turned on, the drive motor 17 is energized, and the blades 26 start rotating integrally with the shaft 21 via the V belt 25. As a result, the glutinous rice in the container 7 is kneaded, and the glutinous rice rises after a predetermined time. If the drive motor 17 is overloaded or its rotation is restricted during operation of the drive motor 17, the winding temperature of the drive motor 17 rises, but the drive motor 17 rises to a certain temperature. Then, the safety device 34 operates and the energization of the drive motor 17 is forcibly cut off. In this case, if the safety device 34 should fail or the control circuit in the control board 32 malfunctions, the temperature of the drive motor 17 will continue to rise and the insulating coating of the winding will melt and cause a rare short circuit. Wake up,
Eventually, that part ignites and the winding is broken. However, since the outer peripheral surfaces of the drive motors 17 are all surrounded by the partition member 61 made of a non-combustible material, the deformation or melting of the cooking motor body 1 due to the ignition of the drive motors 17 and the periphery of the drive motors 17 are prevented. This partition member affects the parts
