DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for attaching a side heater mounted on an inner frame K11 to a jar rice cooker.

従来、ジャー炊飯器の内枠には側部ヒータが捲装され、
炊飯および保温が行なわれていた。
Conventionally, a side heater was wrapped around the inner frame of a jar rice cooker.
Rice was being cooked and kept warm.

In recent years, it has been found that when cooking rice, if you raise the temperature of the rice in the upper part of the pot before the rice in the lower part, the rice will cook better.

In order to realize the rice cooking method, there is provided a pot for storing rice to be cooked, an inner frame having a pot storage section for storing the pot, and a heating provided around the outer periphery including the bottom of the pot by the pot storage section. a high-temperature type heater provided so as to be spaced apart from the pot so as to expose the internal pressure of the intermediate portion;
Some of the high-temperature type heaters have a structure in which the pot is arranged so as to heat the surrounding area of the pot rather than the bottom center area during rice cooking. As another method, there is a method in which a cast-in heater at the bottom is made to generate heat during rice cooking, and a side heater wrapped around the outer surface of the inner frame is made to generate heat at the beginning or continuously of rice cooking.

However, in the former method, a high-temperature heater installed at a distance from the pot at the bottom of the inner frame generates heat, and the heat is transferred to the top by air convection through the heating space to heat the cooked rice in the upper part of the pot. However, this method does not have the effect of raising the temperature of the rice in the upper part of the pot higher than the temperature in the lower part, and depending on the cooking conditions such as the outside temperature, the temperature of the rice in the upper part of the pot may change. Cases arise where it is not possible to raise the temperature in advance of the lower part. In addition, it is known that this heating method has lower thermal efficiency than in the past, and the high-temperature heater itself becomes red hot when energized, shortening its lifespan. It needed structure. Furthermore, in order to keep warm, not only a bottom heater but also a side heater was required. On the other hand, the latter is an indirect heating method in which the inner frame is heated with a side heater and the heat is used to heat the pot, so the local heating effect on the top is small and the amount of heat given to the cooked rice at the top of the pot is small. Poor thermal efficiency. Therefore, in order to realize the rice cooking method, the side heater must generate a high amount of heat, and the heater itself must be highly heat resistant and expensive.

また内枠、外枠、その他も耐熱構造とする必要が生じる
欠点があった。
Furthermore, there is a drawback that the inner frame, outer frame, and the like must also have a heat-resistant structure.

Moreover, according to the two rice cooking methods, it is necessary to fix the side heater to the inner frame. For this reason, Figure 4, Figure 51!1
As shown in K, a side heater 7' housed in an aluminum plate 19 was wrapped around the outer surface of the inner frame 2', and the ends were fastened and fixed with screws 2o.

According to this configuration, when the temperature rises due to heat generation, the aluminum plate 19 thermally expands in the circumferential direction and comes off from the inner frame 2', which makes it impossible to achieve close contact with the inner frame when heat is applied. . On the other hand, the cost of aluminum plates is high, the number of parts is large, and automation of the work is difficult, making side heaters expensive.

Another method is to wrap the side heater directly around the inner frame while adhering it, but in this case, the adhesive wrapping method requires complicated equipment, making it difficult to rationalize the process, and has the disadvantage of poor repairability.

The rice cooking method with the above configuration will be described with reference to FIG. 2. When the rice cooking operation start switch e is operated, the switch 12 linked thereto is operated, and both are closed to the KN and O sides. At this time, the bottom casting heater 3 and the side heater 7 form a parallel circuit, with the bottom casting heater a heating the bottom of the pot and the entire pot, and the side heater 7 intensively heating the top of the pot. At this time, most of the heat generated by the side heater 7 heats the upper part of the pot, and the heat that heated the inner frame is also radiated to the pot. For this reason, the rice in the upper part of the pot is heated intensively and effectively.
The rice cooking method described above is made possible. In the later stages of rice cooking, the magnetic thermostat 1o is activated by detecting the temperature at the bottom of the pot, and the switches 9 and 12 are activated to reverse both to the N and C sides. At this time, bottom cast heater 3. The side heater 7 and the heater 8 in the outer lid are connected in series, and together form a heat-retaining circuit that heats and heats the rice from its entire circumference with a small amount of electric power.

As is clear from the above explanation, according to the present invention, the amount of heat generated by the side heater is extremely efficiently radiated to the cooked rice in the upper part of the inner pot. A good temperature rise is possible. Therefore, the side heater needs only a small amount of heat and can be used at a low price.In addition, it is possible to cook rice well even if parts such as the inner frame and outer frame do not have a heat-resistant structure. be able to.
