Abstract

Proposed is an electric kettle in which a main body is provided with a water level window. The electric kettle of the present disclosure includes the main body configured to receive water or food therein and provided with the water level window through which the level of water contained inside the main body is seen, a lid provided on an open upper side of the main body so as to cover the open upper side of the main body, and a base provided at a lower side of the main body so as to support the main body, wherein a flow path in which a fluid flows is formed in the water level window and has a bottom surface formed to be inclined. According to such a configuration, a fluid remaining inside the water level window decreases.

First claim

What is claimed is:

1. An electric kettle comprising:
a main body to receive fluid therein and provided with a fluid level window through which a level of the fluid contained inside the main body is visible;
a lid for covering an open upper side of the main body; and
a base for supporting the main body at a lower side of the main body,
wherein a flow path in which the fluid flows is formed in the fluid level window and a bottom surface of the flow path has a downward inclination relative to the main body,
wherein an entrance flow path is formed in each of upper part and lower part of the fluid level window, the entrance flow path connecting the flow path inside the fluid level window to an inside of the main body, and a bottom surface of the entrance flow path formed in the lower part of the fluid level window is inclined,
wherein the entrance flow path at the lower part of the fluid level window having an end portion depressed to form an entrance flow path groove, the entrance flow path groove is slantingly inclined to have a depth gradually decreasing going toward the main body.

2. The electric kettle of claim 1 , wherein the fluid level window comprises an inner cover and an outer cover having shapes corresponding to each other and coupled to each other, and the flow path is formed between the inner cover and the outer cover.

3. The electric kettle of claim 2 , wherein an inner inclined surface and an outer inclined surface are formed on the inner cover and the outer cover, respectively, so as to guide the flow of the fluid contained in the flow path to the main body.

4. The electric kettle of claim 2 , wherein the entrance flow path is perpendicular to the flow path.

5. The electric kettle of claim 2 , wherein a corner angle formed between a surface of the flow path and a surface of the entrance flow path at the lower part of the fluid level window is angulated.

6. The electric kettle of claim 2 , wherein a corner angle formed between a surface of the entrance flow path at the lower part of the fluid level window and an outer surface of the inner cover has a is angulated.

7. The electric kettle of claim 2 , wherein a corner angle formed between a surface of an entrance flow path at an upper part of the inner cover and an outer surface of the inner cover has a curvature larger than a curvature of zero degrees, and
a corner angle formed between a surface of an entrance flow path at a lower part of the inner cover and an outer surface of the inner cover is angulated.

8. The electric kettle of claim 1 , wherein the entrance flow path groove has a length shorter than a length of the entrance flow path at the lower part of the water level window.

9. The electric kettle of claim 8 , wherein an inner end of the entrance flow path at the lower part of the fluid level window is located more inner toward the main body than an inner end of the entrance flow path groove.

10. The electric kettle of claim 8 , further comprising:
a packing which blocks a gap between the inner cover and the main body.

11. The electric kettle of claim 10 , wherein an inner end of the packing is located more inner toward the main body than an inner end of the entrance flow path groove.

12. The electric kettle of claim 1 , wherein the fluid level window comprises an inner part and an outer part integrated with each other, and the flow path is formed between the inner part and the outer part.

13. The electric kettle of claim 12 , wherein an entrance flow path is provided in each of upper part and lower part of the fluid level window, the entrance flow path connecting the flow path formed inside the fluid level window to an inside of the main body.

14. The electric kettle of claim 1 , wherein the main body is a double structure such that the main body comprises an inner body constituting an inner appearance of the main body and an outer body constituting an outer appearance of the main body, and
the fluid level window comprises an inner cover that is opaque and coupled to the inner body, and an outer cover that is transparent and coupled to the outer body.

15. The electric kettle of claim 14 , wherein the flow path in which the fluid flows is formed between the inner cover and the outer cover, and the inner cover and the outer cover are coupled to each other by fusion.

16. The electric kettle of claim 14 , wherein the fluid level window is mounted to the main body by press-fitting thereto, and at least one of the inner cover or the outer cover is made of a tritan material.
