Description

[Detailed Description of the Invention] The present invention relates to a water boiling pot in which water contained in the pot body can be heated and kept warm by an electric heater.

In conventionally known water boiling pots of this type, the inner lid that covers the wide opening of the inner container is clamped and fixed by a lockable outer lid, so when the pot falls over, the impact releases the locking mechanism, causing the outer lid to close. There is a danger that the lid and inner lid may be opened at the same time and the contents may spill out.

In view of the above-mentioned problems, the present invention aims to reduce the number of parts by making the mounting structure of the inner lid so that it does not easily come off and eliminating the locking mechanism of the outer lid, thereby achieving low cost and The purpose is to provide a safe kettle.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a kettle according to an embodiment of the present invention will be described with reference to the accompanying drawings.

In Figs. 1 and 2, numeral 1 indicates the pot body, 2
is an outer lid that covers the upper opening of the pot body 1 so that it can be opened and closed freely;
3 and 4 are an outer case and an inner container that constitute the outer and inner peripheral surfaces of the pot body 1, and 5 is an outer case 3 and an inner container 4.
A shoulder member 6 that connects the upper opening of the outer case 3 is a bottom lid that covers the bottom opening of the outer case 3, 7 is an electric heater disposed on the outer periphery of the lower part of the inner container 4, and 8 is an opening/closing member attached to the bottom of the inner container 4. The stopper and 9 each indicate a spouting tube.

In this embodiment, the upper end of the inner container 4 has a wide opening 1.
0, and the wide opening 10 is covered by an inner cover 11 that is constructed independently of the outer cover 2.

The inner lid 11 is removably attached to the pot body 1 through helicoidal coupling through engagement between an inward protrusion 12 formed on the inner circumferential surface of the shoulder member 5 and an outward protrusion 13 formed on the outer circumferential surface of the inner cover 11. It will be done.

Further, a gasket 20 is interposed between the inner lid 11 and the upper surface of the collar 4a on the edge of the inner container 40, and when the inner lid 11 is attached, the peripheral edge of the inner lid 11 is placed against the collar 4a by the gasket 20.
0, thereby maintaining watertightness.

A steam vent hole 14 is formed in the center of the inner illumination, and a ball-shaped overturn water stop valve 15 is attached to the steam vent hole 14.

In addition, as a coupling means for the inner lid 11, a screw coupling may be employed instead of the helicoid coupling described above.

On the other hand, the outer lid 2 is attached to the shoulder member 5 via a hinge pin 16 so as to be openable and closable, and has no special locking mechanism and can be opened and closed freely.

Further, the outer lid 2 is formed with a communication hole 17 that communicates the steam vent hole 14 of the inner lid 11 with the outside.

This kettle works as follows.

The water contained in the inner container 4 is heated by an electric heater 7 and hot water is taken out from the pouring pipe 9 by opening the shutoff valve 8 when desired.

At this time, the steam generated is discharged to the outside through the steam vent hole 14 of the inner lid 11 and the communication hole 17 of the outer lid 2.

However, if the kettle is accidentally tipped over, the outer lid 2 will be opened, but since the inner lid 11 is fixedly connected to the pot body 1 by a helicoid connection,
The closed state of the lid is maintained while maintaining watertightness, and the steam vent hole 14 is closed by the overturning water stop valve 15, so that the hot water in the inner container 4 does not leak to the outside.

In the above embodiment, a gravity pouring type kettle has been described, but it goes without saying that the present invention can also be applied to a liquid pumping type kettle using an air pump or the like.

Next, the effects of the water boiling pot of the present invention are listed below.

That is, according to the present invention, (1) an inner lid 11 that covers the wide opening 10 of the inner container 4;
is attached to the inner circumferential surface of the shoulder member 5 of the pot body 1 via a coupling means such as a screw or a helicoid, so that the inner illumination will not be opened even when the pot falls over.
Dangerous accidents such as hot water in the inner container 4 spilling out can be prevented. (2) Since the inner lid 11 is fixedly connected to the pot body 1, the inner lid 11 is fixedly connected to the outer lid 2. There is no need for a locking mechanism to prevent falls, and the number of parts can be reduced, leading to cost reductions.

(3) Since the inner container is pressed into contact with the collar 4a on the edge of the inner container 40 via the packing 20, watertightness is maintained and water leakage can be prevented when the container falls over.

It has such practical effects.
