Abstract

Provided is a food waste disposer. The food waste disposer according to an embodiment of the disclosure includes: a housing; a grinder detachably installed inside the housing and configured to grind food waste accommodated therein; and a deodorizer positioned to a side of the grinder, and configured to suck a smell generated from the grinder and discharge the smell to outside of the housing, wherein the grinder includes: a grinding case; a rotating grinder including a plurality of blades rotatably installed at different heights inside the grinding case; and a wall grinder including a protrusion protruding inward from the grinding case at a different height from the plurality of blades, the wall grinder detachably installed on a side wall of the grinding case.

First claim

What is claimed is:

1. A food waste disposer comprising:
a housing;
a grinder detachably installed inside the housing and configured to grind food waste accommodated therein; and
a deodorizer positioned to a side of the grinder, and configured to suck a smell generated from the grinder and discharge the smell to outside of the housing,
wherein the grinder comprises:
a grinding case;
a rotating grinder including a plurality of blades rotatably installed at different heights inside the grinding case; and
a wall grinder including a protrusion protruding inward from the grinding case at a different height from the plurality of blades, the wall grinder detachably installed on a side wall of the grinding case, wherein the wall grinder includes a chamfer formed at an outer surface of the protrusion in such a way as to be inclined with respect to the outer surface of the protrusion.

2. The food waste disposer of claim 1 , wherein the rotating grinder comprises:
a center body installed at a center of the grinding case and receiving power; and
a first blade extending toward the side wall of the grinding case from the center body, wherein the first blade includes a grinding portion extending in parallel to the side wall of the grinding case and configured to separate food waste stacked on the side wall.

3. The food waste disposer of claim 2 , wherein:
the grinding portion is a first grinding portion, and
the first blade further includes a second grinding portion connected to the first grinding portion and extending horizontally with respect to a bottom plate of the grinding case.

4. The food waste disposer of claim 2 , wherein the rotating grinder further comprises a second blade curved from the center body and extending toward the side wall of the grinding case.

5. The food waste disposer of claim 4 , wherein the second blade comprises a blade chamfer inclined with respect to a rotation direction of the rotating grinder.

6. The food waste disposer of claim 2 , wherein the rotating grinder comprises a third blade extending from the center body toward the side wall of the grinding case, and including an uneven portion formed at a lower side of the third blade to rake out food waste existing on a bottom plate of the grinding case.

7. The food waste disposer of claim 1 , wherein the rotating grinder comprises:
a first blade including a grinding portion extending in parallel to the side wall of the grinding case;
a second blade curved and extending along a rotation direction of the rotating grinder; and
a third blade formed at a lower location than the second blade.

8. The food waste disposer of claim 7 , wherein the wall grinder comprises:
a first protrusion positioned between the first blade and the second blade; and
a second protrusion positioned between the second blade and the third blade.

9. The food waste disposer of claim 1 , further comprising:
an upper frame positioned in an upper portion of the housing and including an opening in which the grinder is inserted; and
a housing cover rotatably coupled with one side of the upper frame and the housing cover is configured to open or close the opening.

10. The food waste disposer of claim 9 , wherein the upper frame comprises:
a base forming an upper surface; and
an inlet protruding upward from the base and accommodating a portion of the deodorizer,
wherein a communicating hole communicating with the grinder is formed in the inlet.

11. The food waste disposer of claim 10 , wherein the deodorizer comprises:
a communicating case that is partially accommodated in the inlet, the communicating case positioned behind the grinder; and
a fan installing case connected to the communicating case, and configured to accommodate a circulating fan forming a suction airflow toward the communicating case from the grinder.

12. The food waste disposer of claim 11 , wherein the deodorizer comprises:
a filter configured to filter air sucked from the grinder; and
an exhaust case installed in a side of the filter and communicating with an exhaust hole of the housing, wherein air filtered by the filter flows along the exhaust case.

13. The food waste disposer of claim 9 , further comprising:
a bottom frame positioned below the upper frame and on which the grinder is seated; and
a heater positioned between the bottom frame and the grinder, and configured to heat the grinder.

14. The food waste disposer of claim 1 , further comprising a food waste bin positioned below the grinder to store food waste grinded by the grinder and transferred from the grinder.

15. A food waste disposer comprising:
a housing including an exhaust hole;
a grinder detachably installed inside the housing and configured to grind food waste accommodated therein;
a deodorizer positioned behind the grinder, and configured to suck a smell generated from the grinder and discharge the smell through the exhaust hole of the housing; and
an upper frame positioned in an upper portion of the housing and including:
an opening accommodating the grinder, and
an inlet accommodating a portion of the deodorizer,

wherein the grinder comprises:
a grinding case configured to accommodate food waste therein; and
a rotating grinder rotatably installed inside the grinding case, the rotating grinder includes:
a first blade in which a grinding portion extending in parallel to a side wall of the grinding case is formed to separate food waste from the side wall of the grinding case; and
a second blade formed at a lower height than the first blade; and
a wall grinder including a protrusion protruding inward from the grinding case at a different height from the plurality of blades, the wall grinder detachably installed on a side wall of the grinding case, wherein the wall grinder includes a chamfer formed at an outer surface of the protrusion in such a way as to be inclined with respect to the outer surface of the protrusion.

16. The food waste disposer of claim 15 , wherein the rotating grinder further includes a third blade formed at a lower height than the second blade and including an uneven portion formed toward a bottom plate of the grinding case.

17. The food waste disposer of claim 16 , further include a wall grinder detachably installed on the side wall of the grinding case, and including a protrusion formed at a different height from the first blade, the second blade, and the third blade and extending toward inside of the grinding case.

18. A food waste disposer comprising:
a housing including an opening formed in an upper portion thereof;
a housing cover configured to open or close an upper side of the housing;
a grinder configured to grind food waste, and including:
a grinding case installed through the opening of the housing,
a blade including a grinding portion extending in parallel to a side wall of the grinding case;
a deodorizer positioned behind the grinder, and configured to suck a smell generated from the grinder and filter the smell;
a food waste bin positioned below the grinder and configured to store food waste; and
a wall grinder including a protrusion protruding inward from the grinding case at a different height from the plurality of blades, the wall grinder detachably installed on a side wall of the grinding case, wherein the wall grinder includes a chamfer formed at an outer surface of the protrusion in such a way as to be inclined with respect to the outer surface of the protrusion.
