Further, according to this 1st embodiment, be formed with main body steam passage 54 at lid 9, therefore, with do not form the situation of main body steam passage 54 at lid compared with, effectively can utilize the liquid level space by the top of container.Thereby, it is possible to reduce the height of insulating pot.

Further, according to this 1st embodiment, even if contain liquid near pouring spout 14, this liquid also can be made to be dropped in container 6 by through hole 52a, 52b.Thus, even if when pouring spout 14 is blocked by liquid, the discharge of liquid also can be promoted, the discharge of steam is carried out swimmingly.

In addition, in this 1st embodiment, be provided with through hole 52a, 52b respectively in planar portions 51 and curved face part 53, but the present invention is not limited to this.Such as, also the through hole 52b of the through hole 52a of planar portions 51 and curved face part 53 can be formed by connecting as 1 through hole extended along the vertical direction.In this case, compared with the existing insulating pot not possessing next door 50, the impetus that also can hot water be suppressed to overflow from pouring spout 14 when seething with excitement.

" the 2nd embodiment "

Fig. 9 is the sectional view of the insulating pot of the 2nd embodiment of the present invention.The difference of this insulating pot of the 2nd embodiment and the insulating pot of described 1st embodiment is, the peripheral part of container 6 is provided with pipe 57, and the bottom of container 6 is provided with main body connecting portion 60.

Pipe 57 in the mode extended in the vertical direction such as by the part of welded and installed in the peripheral part of container 6.Be positioned at the steam openings portion 58 of the upper end of pipe 57 to be communicated with the vaporium 55 shown in Fig. 8.The lower ending opening portion 59 being positioned at the bottom of pipe 57 is communicated with main body connecting portion 60.The 2nd steam checkout gear 61 is built-in with at main body connecting portion 60.Lower ending opening portion 59 is positioned near the 2nd steam checkout gear 61.2nd steam checkout gear 61 is the steam of the liquid detecting boiling and automatically mechanically stops the device from Power Block 4 to the power supply of heater 10.

When the liquid in container 6 is heated by heater 10 and seethes with excitement, liquid level rises and falls.The fluctuating of this liquid level increases along with boiling time and becomes large.Thus, when the fluctuating of liquid level arrives next door 50, form liquid film at through hole 52, suppress steam to the discharge of pouring spout 14.Consequently, the steam produced in container 6 enters in vaporium 55, the pressure increase in vaporium 55.

Due to the rising of the pressure in this vaporium 55, the steam entered in vaporium 55 flow in pipe 57 from steam openings portion 58 surgingly, and is supplied to the space near the 2nd steam checkout gear 61 by lower ending opening portion 59.Thus, the temperature of the 2nd steam checkout gear 61 sharply rises, and the 2nd steam checkout gear 61 stops the power supply from Power Block 4 to heater 10.

According to this 2nd embodiment, by having said structure, can in the heating of short time heating-stopping apparatus 10 after boiling.Thereby, it is possible to suppress hot water to overflow from pouring spout 14, thus further can improve security.

The present invention, with reference to accompanying drawing fully recording in association with preferred embodiment, but obviously, for being familiar with everyone of this technology, can carry out various distortion and correction.Such distortion and revise only otherwise depart from the scope of the present invention that appended claims limits, be then interpreted as being included in wherein.
