Abstract

An electric kettle may include a body configured to form a space in which liquid, such as water may be contained, a handle that protrudes from an outer surface of the body, a heating module provided inside of the body to heat liquid inside of the body, an operation portion provided in the handle to operate so as to control an operation of the heating module, and a main printed circuit board (PCB) provided inside of the handle to control the operation of the heating module according to an operation of the operation portion. The body may have a double wall structure including two walls spaced apart from each other, and an electric wire that connects the main PCB and the heating module may be guided from the handle to the heating module through a space between the two walls.

First claim

What is claimed is:

1. An electric kettle, comprising:
a body made of a metal material and including an outer body and an inner body inside of the outer body that form a heat insulation space;
an upper body connected to an upper end of the body and extending upward along a circumference of the body;
a heating module including a heater provided inside of the inner body to heat a fluid inside of the body;
a handle connected to an outer surface of the upper body;
an operation portion provided in the handle to operate so as to control an operation of the heating module;
a main printed circuit board (PCB) provided inside of the handle to control the operation of the heating module according to an operation of the operation portion;
an electric wire outlet formed in the outer body such that the heat insulation space and the handle communicate with each other; and
an electric wire inlet formed in the inner body such that the heat insulation space and a space in which the heating module is disposed communicate with each other, wherein an electric wire that connects the main PCB to the heating module sequentially passes through the electric wire outlet, the heat insulation space, and the electric wire inlet, and wherein an upper end of the handle is connected to the upper body, and a lower end of the handle is spaced apart from an outer surface of the body.

2. The electric kettle of claim 1 , further comprising a display on an upper surface of the handle.

3. The electric kettle of claim 2 , wherein the display comprises:
a plurality of holes provided in the upper surface of the handle; and
a plurality of light emitting diodes that selectively emit light through the plurality of holes, respectively.

4. The electric kettle according to claim 1 , wherein the body is made of a stainless steel material and is formed in a cylindrical shape having an open upper surface and an open lower surface.

5. The electric kettle according to claim 1 , wherein a mounting portion, on which the heating module is mounted, is recessed inside of the inner body.

6. The electric kettle according to claim 5 , wherein the heating module is configured to be inserted into an open lower surface of the inner body, and wherein a circumferential surface of the heating module is inserted into the mounting portion and fixedly mounted to partition a space inside of the inner body in a vertical direction.

7. The electric kettle according to claim 1 , wherein the electric wire outlet is disposed above and vertically aligned with the electric wire inlet.

8. An electric kettle, comprising:
a body made of a metal material and including an outer body and an inner body inside of the outer body that form a heat insulation space;
an upper body connected to an upper end of the body and extending upward along a circumference of the body;
a heating module including a heater provided inside of the inner body to heat a fluid inside of the body;
a handle connected to an outer surface of the upper body;
an operation portion provided in the handle to operate so as to control an operation of the heating module;
a main printed circuit board (PCB) provided inside of the handle to control the operation of the heating module according to an operation of the operation portion;
an electric wire outlet formed in the outer body such that the heat insulation space and the handle communicate with each other; and
an electric wire inlet formed in the inner body such that the heat insulation space and a space in which the heating module is disposed communicate with each other, wherein an electric wire that connects the main PCB to the heating module sequentially passes through the electric wire outlet, the heat insulation space, and the electric wire inlet, and wherein the upper body comprises a spout that is made of a same metal material as a material of the body and faces radially outward to pour the fluid.

9. The electric kettle according to claim 8 , wherein the electric wire outlet is formed at a position radially opposite the spout and accommodated in an open front surface of the handle to communicate with an inside of the handle.

10. An electric kettle, comprising:
a body made of a metal material and including an outer body and an inner body inside of the outer body that form a heat insulation space;
an upper body connected to an upper end of the body and extending upward along a circumference of the body;
a heating module including a heater provided inside of the inner body to heat a fluid inside of the body;
a handle connected to an outer surface of the upper body;
an operation portion provided in the handle to operate so as to control an operation of the heating module;
a main printed circuit board (PCB) provided inside of the handle to control the operation of the heating module according to an operation of the operation portion;
an electric wire outlet formed in the outer body such that the heat insulation space and the handle communicate with each other; and
an electric wire inlet formed in the inner body such that the heat insulation space and a space in which the heating module is disposed communicate with each other, wherein an electric wire that connects the main PCB to the heating module sequentially passes through the electric wire outlet, the heat insulation space, and the electric wire inlet, wherein the electric wire outlet is formed at the upper end of the body, and wherein a body top opening recessed at a position corresponding to the electric wire outlet is formed at a lower end of the upper body.

11. An electric kettle, comprising:
a body made of a metal material and including an outer body and an inner body inside of the outer body that form a heat insulation space;
an upper body connected to an upper end of the body and extending upward along a circumference of the body;
a heating module including a heater provided inside of the inner body to heat a fluid inside of the body;
a handle connected to an outer surface of the upper body;
an operation portion provided in the handle to operate so as to control an operation of the heating module;
a main printed circuit board (PCB) provided inside of the handle to control the operation of the heating module according to an operation of the operation portion;
an electric wire outlet formed in the outer body such that the heat insulation space and the handle communicate with each other; and
an electric wire inlet formed in the inner body such that the heat insulation space and a space in which the heating module is disposed communicate with each other, wherein an electric wire that connects the main PCB to the heating module sequentially passes through the electric wire outlet, the heat insulation space, and the electric wire inlet, and wherein the electric wire outlet is defined by an inner cutout portion cut out at an upper end of the inner body, an outer cutout portion cut out at an upper end of the outer body, and a body top opening opened at a lower end of the upper body.
