Abstract

An electric kettle may include a body made of a metal material, having a vertically open cylindrical shape, and including an outer body forming an outer appearance and an inner body disposed inside of the outer body, an upper body mounted on an upper end of the body and extending upward along the upper end of the body, a lid coupled to the upper body to open and close an open upper surface of the body, a spout that protrudes from a first side of the upper body to pour fluid, such as water, a handle connected to a second side of the upper body facing the spout, a heating module provided inside of the body to heat fluid contained in the inner body, and a base on which a lower surface of the body may be seated and that supplies power to the heating module in a state in which the body is seated. The upper body may include a body top made of a same material as a material of the body and extending upward along the upper end of the body, and a seating member configured to connect an inner surface of the body top and an inner surface of the inner body such that the upper body and the body are connected inside.

First claim

What is claimed is:

1. An electric kettle, comprising:
a body made of a metal material, having a cylindrical shape with an open upper surface and an open lower surface, and comprising an outer body forming an outer appearance and an inner body disposed inside of the outer body;
an upper body mounted on an upper end of the body and extending upward along the upper end of the body;
a lid coupled to the upper body to open and close the open upper surface of the body;
a spout that protrudes from a first side of the upper body to pour fluid;
a handle connected to a second side of the upper body facing the spout;
a heating module provided inside of the body to heat fluid contained in the inner body; and
a base on which a lower surface of the body is seated and that supplies power to the heating module in a state in which the body is seated, wherein the upper body comprises:
a body top made of a same material as a material of the body and extending upward along the upper end of the body; and
a seating member configured to connect an inner surface of the body top and an inner surface of the inner body such that the upper body and the body are connected inside, wherein an outer surface of an upper end of the seating member contacts the inner surface of the body top and an outer surface of a lower end of the seating member contacts the inner surface of the inner body.

2. The electric kettle according to claim 1 , wherein the inner body, the outer body, and the body top are made of a same material.

3. The electric kettle according to claim 1 , wherein an outer diameter of the body top is equal to an outer diameter of the outer body.

4. The electric kettle according to claim 1 , wherein the inner body and the outer body are spaced apart from each other to form a heat insulation space.

5. The electric kettle according to claim 1 , wherein an inner upper end portion and an outer upper end portion joined to each other are formed at upper ends of the inner body and the outer body, and wherein a space in which the inner upper end portion and the outer upper end portion joined to each other are accommodated is formed between a lower end of the body top and the upper end of the seating member.

6. The electric kettle according to claim 1 , wherein the handle comprises:
an operation portion configured to operate the electric kettle; and
a printed circuit board (PCB) configured to control the heating module provided inside of the body.

7. The electric kettle according to claim 6 , wherein an electric wire that connects the PCB to the heating module is guided through a space between the outer body and the inner body.

8. The electric kettle according to claim 1 , wherein the seating member comprises:
an upper packing connected to the upper end of the seating member and press-fitted into a lower end of the body top; and
a lower packing connected to the lower end of the seating member and press-fitted into an upper end of the inner body.

9. The electric kettle according to claim 8 , wherein the seating member comprises:
a seating member upper portion having an inner diameter equal to an inner diameter of the body top; and
a seating member lower portion slanted downward from the seating member upper portion, such that an extended lower end is formed to have an inner diameter equal to an inner diameter of the inner body.

10. The electric kettle according to claim 9 , wherein the upper packing is connected to an outer surface of the seating member upper portion, and wherein the lower packing is connected to an outer surface of the seating member lower portion.

11. The electric kettle according to claim 8 , wherein a rounded portion that narrows an outer diameter and extends upward is formed at an upper end of the upper packing.

12. The electric kettle according to claim 11 , wherein a lower end of the upper packing is stepped and configured to be caught and restrained by a packing groove of the body top.

13. The electric kettle according to claim 8 , wherein the inner body comprises:
an inner upper end portion forming an upper end of the inner body and connected to the outer body;
an inner slanted portion that is slanted downward from the inner upper end portion in an inward direction; and
a body restraint groove into which the lower packing is press-fitted at a lower end of the inner slanted portion.

14. The electric kettle according to claim 13 , wherein the seating member covers the inner upper end portion, the inner slanted portion, and the body restraint groove in a state in which the body top and the inner body are connected.

15. The electric kettle according to claim 9 , wherein a lid support that protrudes to support a lower surface of the lid when the lid is mounted is formed on an inner surface of the seating member.

16. The electric kettle according to claim 15 , wherein an upper end of the body top and an upper end of a circumferential surface of the lid are disposed at a same height in a state in which the lid is seated on the lid support.

17. The electric kettle according to claim 9 , wherein the seating member is made of a plastic material.

18. The electric kettle according to claim 1 , wherein the outer body is formed in a cylindrical shape and is formed such that an upper end and a lower end of an outer surface thereof have a same outer diameter.

19. The electric kettle according to claim 1 , wherein an outer surface of the base, the outer body, and the body top are formed in a cylindrical shape having a same outer diameter and are made of the same stainless steel.

20. An electric kettle, comprising:
a body having an open upper surface and an open lower surface, and comprising an outer body and an inner body disposed inside of the outer body to form a heat insulation space therebetween;
an upper body mounted on an upper end of the body;
a lid coupled to the upper body to open and close the open upper surface of the body;
a handle connected to a side of the upper body;
a heating module provided inside of the body to heat fluid contained in the inner body; and
a base on which a lower surface of the body is seated and that supplies power to the heating module in a state in which the body is seated, wherein the upper body comprises:
