ように下部にファンモータを設けたものもある。2. Description of the Related Art A conventional heating cooker such as a rice cooker has a structure in which a cooking container is detachably mounted on a heater to cook the food, and even if the cooking becomes dirty, it can be easily removed from the main body and cleaned. In addition, as disclosed in Japanese Patent Application Laid-Open No. 62-161313, for example, a fan motor is provided at a lower portion.

温度ヒューズ装置を設けざるをえなかった。Problems to be Solved by the Invention In the conventional structure described above, as a result of the temperature rising only at the lower surface of the container in contact with the heater, so-called uneven heating occurs in which the temperature in the middle and upper portions of the container is relatively low. In addition, since there is a certain thermal resistance between the heater and the container, the larger the output of the heater, the greater the amount of heat loss. As a result, the heater is overheated and the life of the heater is shortened. Furthermore, in the case of a so-called abnormal heating state in which the control device has failed, the only security device, that is, a temperature fuse device that operates by quickly catching the abnormal temperature rise of the heater is required, but in principle, the method of fixing the temperature fuse device to the heater is the most common. Although good responsiveness can be predicted from the principle of heat conduction, it is of course not realized with products where the heater temperature is higher than the operating temperature of the thermal fuse device. When the thermal resistance between the heater and the container increases, or as the output of the heater increases, the amount of heat loss increases, and the heater overheats. A thermal fuse device had to be provided in that part.

In addition to fixing the temperature fuse device to the heater, a blower is provided at the lower portion of the heater so that air taken in from outside the main body passes through the lower surface of the heater, passes through the outside of the container, and is forcibly discharged from the upper portion of the main body.

In addition to eliminating uneven heating, malfunction of the thermal fuse device is also eliminated.

される。When the food is put into the container 4 and the opening of the container 4 is closed by the lid 7 and the heater 2 and the blower 3 are operated, the heater 2 generates heat, and heat is conducted from the upper surface of the heater 2 to the lower surface of the container 4. You. On the other hand, the lower surface of the heater 2 is cooled by the air taken in from the outside of the main body 1 by the blower 3, and as a result, the taken air becomes hot air and passes through the space between the outer wall of the container 4 and the inner wall of the main body 1. The wind heats the side surface of the container 4 and is forcibly discharged from around the upper portion of the main body 1. Therefore container 4
Is heated from the lower surface, the side surface of the container 4 is added, and the container 4 is uniformly heated up and down, so that cooking without uneven heating is performed.

ヒーター２の寿命を縮めることがない。The temperature fuse device 5 fixed to the lower surface of the heater 2 is cooled by air taken in from the outside of the main body 1 by the blower 3 and is kept at a temperature sufficiently lower than its operating temperature. Since the temperature and output of 2 are controlled, the temperature fuse device 5 does not malfunction. However, in an abnormal state such as when the blower 3 is locked or the control device 6 fails, the temperature of the heater 2 rapidly rises, and the temperature fuse device 5 fixed to the lower surface of the heater 2 also has a structural characteristic. It operates quickly with heat, minimizing damage. Furthermore, the lower surface of the heater 2 is cooled by the air taken in from the outside of the main body 1 by the blower 3, and the overheating of the heater 2 based on the thermal resistance between the heater 2 and the container 4 is prevented, so that the life of the heater 2 is not shortened. .

In addition, the temperature of the control unit does not rise due to the heat of the heater, eliminating the need for a conventional heat shield device, which is highly effective in terms of cost and space. Nor does it shrink. Further, even if the blower is locked or the control device is in an abnormal state such as failure, the temperature fuse device is fixed to the lower surface of the heater, so that the device operates quickly with heat, so that no security device is required. In addition, since the heat energy on the lower surface of the heater, which has been wasted heat, changes the air taken in by the blower into warm air, and heats the side of the container, it is possible to perform cooking without uneven temperature.
