The blender includes a container body in which food is received, a main body provided under the container body and configured to support the container body, a container lid mounted detachably to an upper surface of the container body and configured to open and close the upper surface of the container body, and a blade assembly which crushes food contained in the container body by a blade unit, wherein an inclined surface is formed on each of leading and rear edge portions of the blade unit constituting the blade assembly such that the inclined surface has thickness decreasing gradually toward an end thereof. In such a blender, the cutting ability of materials by the blade unit is increased and noise thereof is decreased. ## Claims ### Claim 1 A blender comprising: a container body in which food is received; a main body to support the container body; a container lid detachably mountable to an upper surface of the container body to open and close the upper surface of the container body; and a blade assembly comprising a main blade unit which crushes the food, and an auxiliary blade unit provided at a side of the main blade unit to support the crushing of the food, wherein each of plurality blades of the main blade unit have different bending angle and twisting angle, wherein inclined surfaces are formed on leading and rear edge portions of the main blade unit, respectively, such that the inclined surfaces have thickness decreasing gradually going toward an end of the leading and rear edge portions, wherein the inclined surfaces are formed on a lower surface of the leading and rear edge portions of the main blade unit, respectively, and wherein a length of a lead width of the inclined surface formed on the lower surface of the leading edge portion of the main blade unit is 6 mm or more, and wherein the leading edge portion of the main blade is configured to be higher than the rear edge portion thereof. ### Claim 2 (depends on 1) The blender of claim 1, wherein the leading edge portion of the main blade unit comprises a corrugated shape. ### Claim 3 (depends on 2) The blender of claim 2, wherein the corrugated shape comprises at least three corrugated shapes. ### Claim 4 (depends on 3) The blender of claim 3, wherein the corrugated shape is a shape corresponding to a shape of a sawtooth. ### Claim 5 (depends on 1) The blender of claim 1, wherein the auxiliary blade unit intersects with the main blade unit. ### Claim 6 (depends on 5) The blender of claim 5, wherein the auxiliary blade unit intersects with the main blade unit at 45°. ### Claim 7 (depends on 6) The blender of claim 6, wherein an inclined surface is formed on a leading edge portion of the auxiliary blade unit such that the inclined surface has thickness decreasing gradually going toward an end of the auxiliary blade unit. ### Claim 8 (depends on 1) The blender of claim 1, wherein a blade tip having a triangular shape is formed on an end part of the main blade unit. ### Claim 9 (depends on 8) The blender of claim 8, wherein each edge of the blade tip comprises a streamlined shape or curvature. ### Claim 10 A blender comprising: a container body in which food is received; a main body to support the container body; a container lid detachably mountable to an upper surface of the container body to open and close the upper surface of the container body; and a blade assembly comprising a main blade unit which crushes the food, and an auxiliary blade unit provided at a side of the main blade unit to support the crushing of the food, wherein each of plurality blades of the main blade unit have different bending angle and twisting angle, wherein inclined surfaces are formed on leading and rear edge portions of the blade unit, respectively, such that the inclined surfaces have thickness decreasing gradually going toward an end of the leading and rear edge portions, wherein the inclined surface is formed on a lower surface of the leading edge portion of the main blade unit, and the inclined surface is formed on an upper surface of the rear edge portion of the main blade unit, and wherein a length of a lead width of the inclined surface formed on the lower surface of the leading edge portion of the main blade unit is 6 mm or more, and wherein the leading edge portion of the main blade is configured to be higher than the rear edge portion thereof. ### Claim 11 (depends on 10) The blender of claim 10, wherein the leading edge portion of the main blade unit comprises a corrugated shape. ### Claim 12 (depends on 11) The blender of claim 11, wherein the corrugated shape comprises at least three corrugated shapes. ### Claim 13 (depends on 12) The blender of claim 12, wherein the corrugated shape is a shape corresponding to a shape of a sawtooth. ### Claim 14 (depends on 10) The blender of claim 10, wherein the auxiliary blade unit intersects with the main blade unit. ### Claim 15 (depends on 14) The blender of claim 14, wherein the auxiliary blade unit intersects with the main blade unit at 45°. ### Claim 16 (depends on 15) The blender of claim 15, wherein an inclined surface is formed on a leading edge portion of the auxiliary blade unit such that the inclined surface has thickness decreasing gradually going toward an end of the auxiliary blade unit. ### Claim 17 (depends on 10) The blender of claim 10, wherein a blade tip having a triangular shape is formed on an end part of the main blade unit. ### Claim 18 (depends on 17) The blender of claim 17, wherein each edge of the blade tip comprises a streamlined shape or curvature.
