Abstract

The disclosure relates to a food waste recycling appliance having a hollow reservoir which can collect liquid generated during a cycle of operation, drain the collected liquid, and provide an air flow path for the removal of odors.

First claim

What is claimed is:

1. A liquid reservoir for a food waste recycling appliance, with a fan, that generates liquid during a recycling operation, the liquid reservoir comprising:
a generally U-shaped body, with a hollow interior, having first and second arm portions joined by a web portion, each of the first and second arm portions having a proximal end at the web portion and a distal end remotely spaced from the web portion, with at least some of the first arm, second arm, and web portions at least partially bounding an interstitial space exterior of the U-shaped body;
a food waste through opening defined by an exterior surface of the U-shaped body and passing through the interstitial space;
a liquid inlet located in the distal end of the first arm portion configured to fluidly connect to a source of liquid in a food waste recycling appliance to the hollow interior;
an air inlet fluidly coupled to the hollow interior and located in the distal end of one of the first and second arm portions; and
an air outlet fluidly coupled to the hollow interior and located in the distal end of the other of the first and second arm portions;
wherein the air outlet is configured to connect to the fan to cause air to move from the air inlet through the hollow interior along the first arm portion, the web portion, and the second arm portion to the air outlet.

2. The liquid reservoir of claim 1 further comprising a drain outlet near a junction of the web portion and one of the first or second arm portions.

3. The liquid reservoir of claim 2 wherein the first and second arm portions and the web portion have a contiguous bottom wall and a drain outlet is in the bottom wall at the junction of the web portion and one of the first or second arm portions.

4. The liquid reservoir of claim 3 wherein the bottom wall slopes toward the drain outlet.

5. The liquid reservoir of claim 4 wherein the bottom wall of the web portion and the bottom wall of the one of the first or second arm portions both slope toward the drain outlet.

6. The liquid reservoir of claim 4 further comprising legs to support the first and second arm portions and the web portion in the food waste recycling appliance, and the slope of the bottom wall is relative to the legs.

7. The liquid reservoir of claim 1 further comprising a rib joining the first arm portion to the second arm portion near the distal ends of the first and second arm portions.

8. The liquid reservoir of claim 7 further comprising a recessed area around the air inlet and opening toward the rib wherein liquid overflowing through the air inlet will flow to the rib and then to the opening along the rib.

9. The liquid reservoir of claim 1 further comprising a liquid level sensor disposed in one of the first or second arm portions.

10. The liquid reservoir of claim 1 wherein the first and second arm portions and the web portion are formed of blow molded plastic.

11. A food waste recycling appliance comprising:
a liquid reservoir comprising:
a generally U-shaped body, with a hollow interior, having first and second arm portions joined by a web portion, each of the first and second arm portions having a proximal end at the web portion and a distal end remotely spaced from the web portion, with at least some of the first arm, second arm, and web portions at least partially bounding an interstitial space exterior of the U-shaped body;
a food waste through opening defined by an exterior surface of the U-shaped body, passing through the interstitial space;
a liquid inlet fluidly connected to the hollow interior and located in the distal end of the first arm portion and connected to a source of liquid in the food waste recycling appliance;
an air inlet fluidly connected to the hollow interior and located in the distal end of one of the first and second arm portions; and
an air outlet fluidly connected to the hollow interior and located in the distal end of the other of the first and second arm portions;
a food waste container located below the food waste through opening of the liquid reservoir;
a fan connected to the air outlet of the liquid reservoir; and
a filter downstream of the fan to treat air exiting the hollow, generally U-shaped body;
wherein the fan causes air to move through the generally U-shaped body from the air inlet to the air outlet where it is treated at the filter.

12. The food waste recycling appliance of claim 11 , further comprising a drain outlet near a junction of the web portion and one of the first or second arm portions.

13. The food waste recycling appliance of claim 12 wherein the first and second arm portions and the web portion have a contiguous bottom wall and a drain outlet is in the bottom wall at the junction of the web portion and one of the first or second arm portions.

14. The food waste recycling appliance of claim 13 wherein the bottom wall slopes toward the drain outlet.

15. The food waste recycling appliance of claim 14 wherein the bottom wall of the web portion and the bottom wall of the one of the first or second arm portions both slope toward the drain outlet.

16. The food waste recycling appliance of claim 14 further comprising legs to support the first and second arm portions and the web portion in the food waste recycling appliance, and the slope of the bottom wall is relative to the legs.

17. The food waste recycling appliance of claim 11 further comprising a rib joining the first arm portion to the second arm portion near the distal ends of the first and second arm portions.

18. The food waste recycling appliance of claim 17 further comprising a recessed area around the air inlet and opening toward the rib wherein liquid overflowing through the air inlet will flow to the rib and then to the opening along the rib.

19. The food waste recycling appliance of claim 11 further comprising a liquid level sensor disposed in one of the first or second arm portions.

20. The food waste recycling appliance of claim 11 wherein the first and second arm portions and the web portion are formed of blow molded plastic.
