Abstract

The present invention relates to a blender comprising: a jar in which a blade module for grinding food is disposed; an outer case formed from a metal material and having an open bottom surface; an inner case formed from a plastic material, inserted through the open bottom surface of the outer case, and accommodated inside the outer case; a motor assembly mounted on the inner space of the inner case and for rotating the blade module; a mounting part protruding so as to pass through from the top surface of the inner case to the top surface of the outer case and having the jar mounted thereon; and a bottom cover covering the open bottom surface of the outer case.

First claim

The invention claimed is:

1. A blender comprising:
a jar in which a blade to crush food is disposed;
an outer case made of a metal material, the outer case having an opened bottom surface;
an inner case made of a plastic material, the inner case disposed through the opened bottom surface of the outer case and accommodated inside the outer case;
a motor assembly mounted at an inner space of the inner case, the motor assembly to rotate the blade;
a seating portion which protrudes from a top surface of the inner case to pass through a top surface of the outer case and on which the jar is seatable;
a seating portion decor having a same texture as the outer case and defining an outer appearance of the seating portion, the seating portion decor mounted at a circumferential surface of the seating portion; and
a bottom cover to shield the opened bottom surface of the outer case.

2. The blender according to claim 1 , wherein the outer case has a box shape with the opened bottom surface, and
a top surface opening through which the seating portion passes is defined at the top surface of the outer case.

3. The blender according to claim 2 , comprising a lower decor to cover a gap between the top surface opening and the seating portion, the lower decor disposed between the top surface opening and the seating portion.

4. The blender according to claim 3 , wherein the lower decor is made of a plastic or a rubber material to seal the gap between the seating portion and the outer case.

5. The blender according to claim 1 , wherein the seating portion is stepped in a vertical direction, and
in the state in which the jar is mounted at the seating portion, an outer surface of the jar and an outer surface of the seating portion are disposed to be in the same plane.

6. The blender according to claim 1 , wherein the seating portion comprises:
a first seating portion extending upward to pass through the top surface of the outer case, the first seating portion having an outer diameter corresponding to that of an outer circumferential surface of the jar; and
a second seating portion protruding upward from an upper end of the first seating portion, the second seating portion having an outer diameter less than that of the outer diameter of the first seating portion so as to be inserted into a bottom surface of the jar.

7. The blender according to claim 6 , comprising a first seating portion decor and a second seating portion decor, each of which is made of a material having a same texture as the outer case, and are mounted on circumferential surfaces of the first seating portion and the second seating portion, respectively.

8. The blender according to claim 7 , comprising a connection decor to connect an upper end of the first seating portion decor to a lower end of the second seating portion decor, the connection decor provided at a top surface of the first seating portion,
wherein the connection decor is made of a plastic or a rubber material.

9. The blender according to claim 8 , wherein the connection decor comprises:
a horizontal portion to shield the top surface of the first seating portion; and
a vertical portion extending upward from an inner end of the horizontal portion, the vertical portion in contact with a lower end of the second seating portion decor.

10. The blender according to claim 8 , wherein the connection decor is in contact with a lower end of the jar when the jar is mounted on the seating portion.

11. The blender according to claim 1 , comprising a touch module provided between the top surface of the outer case and the top surface of the inner case, the touch module to detect a touch manipulation of the outer case to operate the blender.

12. The blender according to claim 11 , comprising:
a display portion constituted by a plurality of holes passing through the top surface of the outer case to display an operation state of the blender; and
a display disposed below the display portion, the display to irradiate light that passes through the holes,
wherein the operation state of the blender is displayed in the form of a character or figure by a combination of the holes through which the light irradiated from the display passes.

13. The blender according to claim 12 , wherein the touch module and the display module, which are provided to be stepped, are disposed in parallel with each other on the top surface of the inner case, and
the touch module and the display module are in close contact with the bottom surface of the outer case.

14. The blender according to claim 12 , wherein a knob to manipulate an operation of the blender is disposed at a front surface of the inner case while in contact with a mounting portion,
wherein the knob protrudes forward to pass through a knob hole at the front surface of the outer case.

15. The blender according to claim 14 , wherein a knob mounting hole is defined at the front surface of the inner case, and the knob protrudes forward to pass through the knob mounting hole of the inner case.

16. The blender according to claim 15 , further comprising a printed circuit board (PCB) including the mounting portion at which the knob is mounted.

17. The blender according to claim 16 , wherein the PCB is mounted on a front surface of an inside of the inner case.
