電気ポット等の電気貯湯容器に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric hot water storage container, and more particularly to an electric hot water storage container such as a domestic electric kettle for heating a content liquid to keep it hot or warm.

れを先に提案している。2. Description of the Related Art If an inner container can be washed with an electric pot, it is convenient for cleaning and easy to keep clean. In order to achieve this, for the body that has a heating plate with a heater in the bottom,
It is conceivable that the inner container is housed so that it can be taken in and out, placed on the hot platen and heated, and the present applicant has previously proposed this.

【発明が解決しようとする課題】ところで、熱盤のヒー
タとしてシーズヒータを採用するのが、品質管理上、特
に耐溢水性の面で有利である。By the way, it is advantageous in terms of quality control, especially in terms of flooding resistance, to adopt a sheathed heater as the heater of the hot platen.
【０００４】そこで本発明者等は、シーズヒータを用い
た実験を繰り返したところ、着脱する内容器は熱盤上に
載置して加熱する間接加熱方式になるので、同じヒータ
容量でも、ヒータを内容器に直接密着させる加熱方式の
場合に比し、沸騰速度が遅いと言う問題があった。Therefore, the inventors of the present invention repeated experiments using a sheathed heater, and found that the removable inner container was placed on a heating plate and heated by an indirect heating system. There is a problem that the boiling rate is slower than in the case of the heating method in which the inner container is directly adhered.
【０００５】これにシーズヒータの容量を増大して対応
すると、アルミニウム製の熱盤の一部が溶け損じること
があり、危険である。If the capacity of the sheathed heater is increased to cope with this, a part of the aluminum heating plate may fail to melt, which is dangerous.
【０００６】これにつき種々検討した結果、着脱される
内容器の底部面積は小さく、これに見合う大きさとされ
る熱盤も小さいので、シーズヒータの配置によっては、
熱の分散が弱く、熱が局部に集中することが原因してい
ると思われる。As a result of various studies on this, the bottom area of the inner container to be detached and attached is small, and the heating plate of a size commensurate with this is also small. Therefore, depending on the arrangement of the sheath heater,
It seems that the heat is weakly dispersed and the heat is concentrated locally.
【０００７】これらのことは、熱盤に底部が接する内容
器内の内容液を加熱するものであれば、内容器が着脱さ
れるかどうかに係わりなく、全ての電気貯湯容器に共通
するものである。These are common to all electric hot water storage containers, regardless of whether the inner container is attached or detached, as long as the liquid content in the inner container whose bottom is in contact with the hot plate is heated. is there.
【０００８】本発明は、前記のような問題を解消するこ

するものである。In order to solve the above problems, the present invention has a novel arrangement corresponding to the bottom of the inner container of the sheathed heater, so that even if a sufficient boiling rate is obtained by a large capacity heater, the heat An object of the present invention is to provide an electric hot water storage container that can eliminate melting failure of the hot plate due to concentration.

周との間で内外方向に重なって位置する閉じ環状形態を
なすようにしたことを特徴とするものである。In order to achieve the above-mentioned object, the electric hot water storage container of the present invention, which is detachable from the inner container, has a hot plate having a sheathed heater in the bottom of the body. An electric hot water storage container capable of heating the content liquid in the inner container with which the bottom is in contact, the heating plate having a size almost equal to the bottom of the inner container, and a large-capacity seed heater for boiling water in the outermost peripheral part of the heating plate. In addition, a small-capacity sheathing heater for heat insulation is provided inside each of them, and the sheathing heater for retaining heat has an open annular shape in which both terminals are separated in the annular direction, and the sheathing heater for boiling water has both terminals. It is characterized in that the portion has a closed annular shape that is positioned so as to overlap in the inward and outward directions between the annularly separated portion between both terminals of the sheathed heater for heat retention and the outer periphery of the heating plate.
【００１０】特にこの構成は、内容器は器体に対し出し
入れできるように収容され、熱盤上に着脱できるように
載置されるものであると、好適である。In particular, this construction is suitable when the inner container is housed so that it can be taken in and out of the container, and is mounted on the hot plate so as to be detachable.

るのが望ましい。Further, the sheathed heater for heat retention has an open annular shape in which both terminals are separated from each other in an annular direction, and the sheathed heater for boiling water has a volume terminal portion and the sheathed heater for retaining heat has an annular spacing between the volume terminals. It is desirable to form a closed annular shape that is positioned to overlap inward and outward between the portion and the outer circumference of the heating plate.

It is preferable to have it.

けて十分な速度での湯沸かしを行っても、熱盤に溶け損
じが生じるようなことを回避することができる。According to the above construction of the electric hot water storage container with removable inner container according to the present invention, the heater is divided into a large-capacity seed heater for boiling water and a small-capacity seed heater for heat insulation, and the heater is provided on the hot platen. By this, even if it is energized at full capacity, it can be distributed to each part of the hot platen, and especially a large capacity sheathed heater,
It is installed on the outermost peripheral part of the heating plate of approximately the same size as the bottom of the inner container to distribute heat in the annular direction using the large diameter part of the heating plate, so a large-capacity sheathed heater is used for a relatively small heating plate. It is possible to avoid the occurrence of melting failure in the hot platen even if the heating element is provided and water is heated at a sufficient speed.
【００１４】したがって、内容器が器体に対し出し入れ
できるように収容され熱盤に着脱できるように載置され
る電気貯湯容器の場合、内容液の加熱が間接的になる
が、上記の熱盤によって十分な加熱状態が得られる。Therefore, in the case of the electric hot water storage container in which the inner container is housed so that it can be taken in and out of the vessel and is mounted on the hot plate so that it can be detached, the heating of the content liquid is indirect, but the above hot plate is used. As a result, a sufficient heating state can be obtained.

熱盤の熱的安全を図ることができる。Moreover, by arranging both terminals of the sheath heater for boiling water having a large capacity so as to be overlapped inside and outside, heat is dispersed in the circumferential length region longer than the length of one round of the large diameter portion of the hot platen, Moreover, since the overlapping portion of the both terminal portions faces the annularly separated portion between the both terminals of the heat insulating sheathed heater, heat concentration between the heat insulating sheathed heater and the sheathed heater is avoided, so that the heater capacity is improved. And the thermal safety of the hot platen can be increased.

よる熱の局部集中を防止することができる。Since each of the sheathed heaters for boiling water and for keeping warm is embedded in the bead-shaped raised portion on the back surface of the heating plate, the close contact with the bottom of the inner container of the heating plate is ensured, and the thick wall is not thick enough. It is possible to efficiently transfer the heat from the sheathed heater to the heating plate while preventing it from forming, and the overlapping portion of both terminals of the sheathed heater for boiling water is in the same bead-shaped ridge. By embedding, the bead-shaped raised portion forms a portion having a large heat capacity, so that the heat of the portion where the two terminal portions are adjacent and overlapped is sufficiently dispersed and transmitted to the main body of the heating plate. It is possible to prevent local concentration of heat due to overlapping.

を防止することができる。In this case, by embedding each of the sheathed heaters for boiling water and for keeping heat in the bead-shaped raised portion on the back surface of the heating plate, the close contact with the bottom of the inner container of the heating plate is ensured and the thickness is unnecessarily increased. The heat from the sheathed heater is efficiently conducted to the hot platen while preventing the above, and the overlapping portion of both terminals of the sheathed heater for boiling water is embedded in the same bead-shaped ridge. Due to the large heat capacity of the raised portion, the heat of the portion where the two terminal portions are adjacent and overlapped is sufficiently dispersed, so that the localized concentration of heat due to the overlap can be prevented.
