Description

[Detailed description of the invention] This invention relates to an electric kettle that can both heat liquid and keep it warm.The purpose of this invention is to fill the space formed between the outer case and the inner container with a heat insulating material. An object of the present invention is to provide an electric kettle having a structure that makes it easy to use.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An electric kettle according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 denotes a pot body, and 2 denotes a lid body that covers the upper opening of the pot body 1. As shown in FIG.

The pot body 1 includes a cylindrical outer case 3, a bottomed cylindrical inner container 4 to be disposed inside the outer case 3, and a bottom lid 5 to cover the lower end opening of the outer case 3. It is constructed using members as main components.

A shoulder member 6 is interposed between the upper edge 8 of the outer case 3 and the upper edge 10 of the inner container 4 to connect the two by abutting on the former and suspending the latter. A connecting tool, which will be described later, connects the bottom of the inner container 4 and the bottom lid 5 while holding the upper end of the legs 7 that support the pot body 1 between the lower edge 9 of the case 3 and the upper edge 11 of the bottom lid 5. The pot main body 1 is constructed by coupling via 12 and 12.

A small diameter portion 4b is formed in the lower part of the inner container 4 by drawing process.
is formed.

Reference numeral 4a indicates a large diameter portion at the upper part of the inner container 4.

An electric heater 13 for heating is attached by a band 14 to the outer periphery of the small diameter portion 4b.

Furthermore, a cylindrical heat shield plate 15 is disposed outside the electric heater 13 so as to surround it.

That is, a gap 27 is formed between the inner container small diameter section 4b and the heat shield plate 15, and the electric heater 13 is wrapped around the outer periphery of the inner container small diameter section 4b and has both ends 14a, 14a inside the gap 27. It is attached by a band 15 which is connected by a

By doing so, the space 27 can be effectively used for attaching the heater.

Here, the outer diameter of the heat shield plate 15 is the same as or slightly smaller than the outer diameter of the large diameter portion 4a of the inner container.

Then, a cylindrical space 20 is formed between the outer case 3, the inner container large diameter part 4a, and the heat shield plate 15 located below it, and the space 20 is filled with a heat insulating material such as glass wool. The material 21 is filled.

In this case, the outer diameter of the inner container large diameter portion 4a and the outer diameter of the heat shield plate 15 are the same, or the heat shield plate 15 side has a slightly smaller diameter.
The filling operation of the heat insulating material 21 from below can be easily performed.

A pair of mounting ribs 16, 16 are protruded from the lower end opening edge 15a of the heat shield plate 15, facing each other. The heat shield plate 15 is fixed to the base 17 by screws 18, 18, . . . .

Connectors 12.12 for connecting the inner container 4 and the bottom cover 5 are fastened to the mounting base 17 with screws 18.18.

Further, the mounting base 17 is provided with projecting portions 19, 19 for mounting a temperature sensing device (not shown) such as a thermostat. It is made to stand out.

In this way, it is possible to prevent the temperature sensing device from malfunctioning due to the influence of hot air trapped within the heat shield plate 15.

In the drawing, reference numeral 22 denotes a protrusion erected on the lower opening edge 15a of the heat shield plate 15, and the protrusion 22 has the function of preventing the electric heater 13 from falling off.

23 is a screw for fastening the connector 12 and the bottom cover 5, 24 is an outlet hole at the bottom of the inner container 4, 25 is a spouting pipe, and 26 is an opening/closing cock.

Next, the effects of the electric kettle of the present invention are listed below.

That is, according to the present invention, (1) In the lower part of the inner container 4 disposed inside the outer case 3,
A small diameter portion 4b is formed by drawing, and a cylinder having an outer diameter that is the same as or smaller than the outer diameter of the large diameter portion 4a of the inner container 4 is placed outside the electric heater 13 attached to the outer periphery of the small diameter portion 4b. The heat shield plate 15 having a shape of The shape of the portion 20 is simplified, and the filling operation with the heat insulating material 21 can be performed smoothly and easily. Since the electric heater 13 is attached to the small diameter part 4
(3) The electric heater 13 is wrapped around the outer periphery of the small diameter portion 4b of the inner container and both ends 14a, 14 a to inner container small diameter part 4
Since it is attached by the band 15 connected at the gap 27 formed between the heat shield plate 15 and the heat shield plate 15,
There are practical effects such as the void 27 being effectively used as a space for installing a heater.
