Description

本発明は、電気ポットに関する。 The present invention relates to an electric pot.

電気ポットの中の湯水は、内容器の下に設けられた加熱循環管路、または内容器の底面部に設けられた加熱カバーの加熱部材により加熱沸騰させる。 Hot water in the electric pot is heated and boiled by a heating circulation line provided under the inner container or a heating member of a heating cover provided on the bottom surface of the inner container.

しかしながら、加熱循環管路で加熱するのは、内容器の局部的な循環加熱となる欠点があり、加熱部材に接する面だけで加熱しても、給湯配管に入る湯水が、加熱された水だけではなく、加熱されていない周囲の水と混ざりながら給湯配管から出湯することになる。
特開２００３−２５９９７７実開平７−０３９７１７ However, heating in the heating circulation line has the disadvantage of local circulation heating of the inner container. Even if heating is performed only on the surface in contact with the heating member, hot water entering the hot water supply pipe is only heated water. Instead, the hot water is discharged from the hot water supply pipe while mixing with the surrounding unheated water.

湯水の加熱沸騰時間の短縮ができるとともに、水温が下がった湯水をあらかじめ設定した温度に加熱することが出来る。 The boiling time of the hot water can be shortened, and the hot water with the water temperature lowered can be heated to a preset temperature.

円板の円周表面部周方向に流水通路を設けた円板状加熱板部材を円筒状有底内容器の筒底とし、流水通路の始点位置に入水孔、終点位置に出水孔を設け、内容器中に溜まった湯水を加熱する時は加熱板部材の表面部により湯水を直接加熱させるとともに、加熱板部材付近の水と周囲の水とを共に内容器筒底の入水孔に流入させ流水通路の終点の出水孔に連通した給湯配管と循環配管を利用して内容器中に循環する際に、同一の加熱板部材内部の流水通路内壁による加熱をする二重加熱を行う。 The disk-shaped heating plate member provided with a flowing water passage in the circumferential direction of the circumferential surface of the disk is the tube bottom of the cylindrical bottomed inner container, and a water inlet hole is provided at the starting point position of the flowing water passage, and a water outlet hole is provided at the end point position. When heating the hot water accumulated in the inner container, the hot water is directly heated by the surface portion of the heating plate member, and both the water near the heating plate member and the surrounding water are introduced into the water inlet hole at the bottom of the inner container cylinder. When circulating in the inner container using hot water supply piping and circulation piping communicating with the outlet hole at the end point of the passage, double heating is performed by heating by the inner wall of the flowing water passage inside the same heating plate member.

電気ヒータの加熱板部材を内容器の筒底とするとともに、循環配管を利用して、湯水が加熱板部材となる筒底の上面による直接加熱および同一の加熱板部材の内部の流水通路の内壁による二重加熱を行うことにより、湯水の加熱沸騰時間を短縮させることができるだけでなく、あらかじめ定められた温度に達したときに電気ヒータを停止させ、定温加熱することができる。 The heating plate member of the electric heater is used as the cylinder bottom of the inner container, and the inner wall of the flowing water passage inside the same heating plate member is directly heated by the upper surface of the cylinder bottom where the hot water becomes the heating plate member using a circulation pipe. By performing double heating according to, not only can the heating and boiling time of hot water be shortened, but also the electric heater can be stopped and heated at a constant temperature when a predetermined temperature is reached.

図を参照しつつ説明する。 This will be described with reference to the drawings.

図１は電気ヒータＢの加熱板部材Ａの上面正面図である。円筒状有底内容器Ｄの円筒状部の内径と同じ直径の円形板状の加熱板部材Ａが内容器Ｄの筒底部材となる。円板状加熱板部材Ａの側面の周方向に加熱板部材Ａの平面上方視略Ｃ字型の溝状部を設け、溝の開口部を覆い被せて管状となる流水通路Ａ−ｃを設ける（図を参照）。流水通路Ａ−ｃの断面積は給湯配管の断面積と等しくする。流水通路Ａ−ｃの一端を起点として設けた入水孔Ａ−ａは内容器Ｄの内側底面に貫通させ、流水通路Ａ−ｃの終点に給湯配管Ｆと連通させるための出水孔Ａ−ｂを内容器Ｄの筒底の下面まで貫通させる。また入水孔Ａ−ａと出水孔Ａ−ｂの直径がそれぞれ給湯配管Ｆの直径と同じ寸法にすることで、給湯配管Ｆに対し湯水の流れる量を最大限にできる。 FIG. 1 is a top front view of the heating plate member A of the electric heater B. FIG. A circular plate-shaped heating plate member A having the same diameter as the inner diameter of the cylindrical portion of the cylindrical bottomed inner container D serves as the cylinder bottom member of the inner container D. In the circumferential direction of the side surface of the disc-shaped heating plate member A, a substantially C-shaped groove-like portion as viewed from above the heating plate member A is provided, and a flowing water passage A-c that covers the opening of the groove and has a tubular shape is provided. (See figure). The cross-sectional area of the flowing water passage Ac is made equal to the cross-sectional area of the hot water supply pipe. A water inlet hole A-a provided from one end of the water passage A-c as a starting point penetrates the inner bottom surface of the inner container D, and a water outlet hole A-b for communicating with the hot water supply pipe F at the end point of the water passage A-c. The inner container D is penetrated to the bottom surface of the bottom of the cylinder. Further, by making the diameters of the water inlet hole Aa and the water outlet hole Ab the same as the diameter of the hot water supply pipe F, the amount of hot water flowing through the hot water supply pipe F can be maximized.

図２は図１に示した加熱板部材Ａの側面正面図である。流水通路Ａ−ｃの一端に給湯配管Ｆと同じ直径の入水孔Ａ−ａを流水通路Ａ−ｃの始点位置として円板状加熱板部材Ａの上面に向け連通させるよう設け、流水通路Ａ−ｃの他端に出水孔Ａ−ｂを流水通路Ａ−ｃの終点位置として給湯配管Ｆとを連通するよう円板状加熱板部材Ａの下面に設ける。 2 is a side elevation view of the heating plate member A shown in FIG. An inlet hole A-a having the same diameter as the hot water supply pipe F is provided at one end of the flowing water passage A-c so as to communicate with the upper surface of the disc-shaped heating plate member A as a starting point position of the flowing water passage A-c. At the other end of c, a water outlet hole Ab is provided on the lower surface of the disc-shaped heating plate member A so as to communicate with the hot water supply pipe F with the end point of the flowing water passage Ac.

図２または図１に示した流水通路Ａ−ｃは、湯水を加熱するときに筒底となる加熱板部材Ａの上面による直接加熱と同時に、加熱板付近の水と周囲の冷水とを共に筒底の入水孔Ａ−ａに流入させ、湯水が流水通路Ａ−ｃの終点の出水孔Ａ−ｂから給湯配管Ｆに流れさせることで加熱板部材Ａの内部の流水通路Ａ−ｃの内壁により加熱する。流水通路Ａ−ｃの長さが円板状加熱板部材Ａの外周部のほぼ一周に相当するため、湯水の加熱効率を最大限にできる。 The flowing water passage A-c shown in FIG. 2 or FIG. 1 is a cylinder that combines the water near the heating plate and the surrounding cold water simultaneously with the direct heating by the upper surface of the heating plate member A that becomes the bottom of the tube when the hot water is heated. The hot water flows into the hot water supply pipe F from the water outlet hole Ab at the end point of the flowing water passage A-c by flowing into the water inlet hole Aa at the bottom, and by the inner wall of the flowing water passage Ac inside the heating plate member A Heat. Since the length of the flowing water passage A-c corresponds to substantially one round of the outer peripheral portion of the disc-shaped heating plate member A, the heating efficiency of the hot water can be maximized.

図３は電気ポットの筒底側面断面図である。加熱板部材Ａの直径を内容器Ｄの円筒状部の内径と同じにすることで、電気ヒータＢの加熱板部材Ａによる加熱面積が最大になる。加熱手段は加熱板部材Ａの上表面部による加熱だけでなく、出湯用モーターＣを利用することにより湯水が加熱板部材Ａの内部の流水通路Ａ−ｃ中を流れ給湯配管Ｆと循環配管を利用して回流する際に内壁による加熱することにより、同一の加熱板部材による二重加熱を行い、加熱沸騰の時間の短縮することができる。 FIG. 3 is a cross-sectional side view of the bottom of the electric pot. By making the diameter of the heating plate member A the same as the inner diameter of the cylindrical portion of the inner container D, the heating area of the electric heater B by the heating plate member A is maximized. The heating means is not only heated by the upper surface portion of the heating plate member A, but by using a hot water motor C, the hot water flows through the flowing water passage A-c inside the heating plate member A and the hot water supply pipe F and the circulation pipe. By heating with the inner wall when circulating using it, double heating by the same heating plate member can be performed, and the time of heating boiling can be shortened.

湯水を前記二重加熱方式により、内容器Ｄ中の温度が下がった湯水を加熱する際に加熱温度を設定し、水温が所定温度に到達した時点で電気ヒータＢを停止させ、定温加熱することもできる。また内容器Ｄの水量が多い場合でも加熱沸騰時間を短縮することができ、湯水を短時間に所定温度まで加熱することができるため、低い保温温度に設定することで、省エネを図ることができる。 The heating temperature is set when heating the hot water with the temperature in the inner container D lowered by the double heating method, and when the water temperature reaches a predetermined temperature, the electric heater B is stopped and heated at a constant temperature. You can also. Moreover, even when the amount of water in the inner container D is large, the heating and boiling time can be shortened, and hot water can be heated to a predetermined temperature in a short time. Therefore, energy can be saved by setting the temperature to a low temperature. .

循環配管を利用する際に、流路切換コックを常に循環側に位置することにより、内容器Ｄの中に溜まった湯水を加熱するときは、出湯用モーターＣの回転により、揚水管Ｆと循環配管を通って内容器Ｄの中へ循環させながら加熱し、また出湯時の予期せぬ出湯または本体が倒れて湯水が流出するなどのトラブルを防ぐ効果もある。 When heating the hot water accumulated in the inner container D by always positioning the flow path switching cock on the circulation side when using the circulation pipe, the circulation of the hot water pipe F and the circulation by the rotation of the hot water motor C is performed. Heating while circulating through the pipe and into the inner container D, and also has the effect of preventing troubles such as unexpected hot water at the time of hot water or the main body collapses and the hot water flows out.

加熱板部材Ａの流水通路Ａ−ｃ中の湯水の過熱を防ぐため、出湯用モーターＣを停止することにより湯水を循環不能にすると同時に、電気ヒータＢも停止させる。 In order to prevent overheating of hot water in the flowing water passage A-c of the heating plate member A, the hot water supply motor C is stopped to stop circulation of hot water and the electric heater B is also stopped.
