Abstract

A sous vide device (100) including an outer housing (104) within which there is located a heated tube (448) surrounding inner tubular wall (311), with the inner tubular wall (311) providing a first duct (461), and a second duct (462) being provided between the inner tubular wall and outer tubular wall with the first duct (461) and second duct (462) co-operating to provide a fluid flow path extending from an inlet (107) to an outlet (106), with vanes (450) being attached to the inner tubular wall (311) so as to be rotatably driven thereby to cause the liquid to pass along the fluid flow path.

First claim

The invention claimed is:

1. A sous vide device including:
an outer housing;
a first inner wall located within the housing and enclosing a space;
a second inner wall located in the space and enclosing a first duct, with a second duct being located between the first inner wall and second inner wall, with the first duct having a liquid inlet, and the second duct having a liquid outlet adjacent the liquid inlet, with the first duct being connected to the second duct at a position spaced from the inlet and outlet so as to provide a liquid flow path extending from the inlet to the outlet;
rotatably driven vanes associated with the liquid flow path to cause liquid to flow from the inlet to the outlet;
a motor drivingly connected to the vanes to cause rotation thereof; and
a heater operatively associated with the liquid flow path to heat the liquid passing therealong.

2. The sous vide device of claim 1 , wherein the heater is mounted on a surface facing the second duct to heat the liquid as liquid passes along the second duct.

3. The sous vide device of claim 1 , wherein the second inner wall is mounted for rotation about a rotational axis, and is rotatably driven by the motor, with the vanes attached to the second inner wall so as to be rotatably driven thereby.

4. The sous vide device of claim 1 , wherein the vanes are located adjacent the outlet so as to propel the liquid through the outlet from the second duct.

5. The sous vide device of claim 1 , wherein the first inner wall is tubular, and the second inner wall is tubular.

6. The sous vide device of claim 1 , further including a temperature sensor mounted on the first inner wall and to provide a signal indicative of the temperature of the liquid passing along the second duct.

7. The sous vide device of claim 1 , further including a switch operatively associated with the heater to deliver electric power thereto, with the switch being mounted on the first inner wall so as to be at least partly cooled by liquid passing along the second duct.

8. The sous vide device of claim 1 , wherein the motor is mounted to be remote from the inlet and outlet so as to be positioned adjacent where the first duct communicates with the second duct.

9. The sous vide device of claim 1 , wherein the vanes are vanes of an impeller.

10. The sous vide device of claim 1 , further including a first magnetic coupling rotatably driven by the motor, and a second magnetic coupling driven by the first magnetic coupling and associated with the vanes so as to cause rotation thereof.

11. The sous vide device of claim 1 , wherein the second duct is annular in configuration and surrounds the first duct.
