Abstract

An oven including (i) a cooking chamber; and (ii) a water reservoir assembly comprising (a) an inlet, (b) a water storage chamber, (c) an outlet, (d) a fillable state where the inlet is accessible from an external environment to deposit water into the water storage chamber through the inlet, (e) a water supply state where the water reservoir assembly is inserted further into the oven than in the fillable state and the oven is configured to extract water from the water storage container via the outlet to supply steam to the cooking chamber, and (f) a fabric proximate the inlet through which water flows before flowing through the outlet. The fabric is sufficiently porous to permit water that is deposited into the inlet to flow through the fabric and into the water storage chamber of the water reservoir assembly.

Claims (43)

1 . An oven comprising:

a cooking chamber;

a cabinet at least partially surrounding the cooking chamber;

a water reservoir assembly comprising (a) an inlet, (b) a water storage chamber, (c) an outlet, (d) a fillable state where the water reservoir assembly is at least partially extracted from the cabinet and the inlet is accessible from an external environment to deposit water into the water storage chamber through the inlet, (e) a water supply state where the water reservoir assembly is inserted further into the oven than in the fillable state and the oven is configured to extract water from the water storage container via the outlet to supply steam to the cooking chamber, (f) a structural support proximate the inlet that extends into the water storage chamber, and (g) a fabric proximate the inlet through which water flows before flowing through the outlet, the fabric attached to the structural support,

wherein, the fabric prevents at least a portion of steam that backflows through the outlet of the water reservoir assembly and into the water storage chamber from escaping out of the inlet and into the external environment,

wherein, the fabric is non-woven, and

wherein, the structural support is movable to, from, and between (i) a separated state where the structural support and the fabric attached thereto are separated from the water reservoir assembly, and (ii) a coupled state where the structural support and the fabric attached thereto are coupled to the water reservoir assembly.

2 . The oven of claim 1 , wherein

the fabric is sufficiently porous to permit water that is deposited into the inlet to flow through the fabric and into the water storage chamber of the water reservoir assembly.

3 . The oven of claim 1 , wherein

the fabric is adhered to the structural support.

4 . The oven of claim 1 , wherein

the fabric comprises (i) a top portion disposed proximate the inlet of the water reservoir assembly and (ii) a bottom portion that extends into the water storage chamber and is elevated lower than the top portion.

5 . The oven of claim 1 , wherein

the water reservoir assembly further comprises (i) a top piece through which the inlet is disposed and (ii) a bottom piece that defines the water storage chamber, the bottom piece being coupled to the top piece.

6 . The oven of claim 5 , wherein

the structural support sits upon the top piece of the water reservoir assembly in the coupled state.

7 . The oven of claim 6 , wherein

the structural support comprises (i) a lip that sits upon the top piece while the structural support is in the coupled state and (ii) support bars that extend downward from the lip and under the fabric.

8 . The oven of claim 1 , wherein

the water reservoir assembly further comprises a front and a rear; and

the water storage chamber comprises a bottom surface that slopes downward from the front to the rear.

9 . The oven of claim 1 , wherein

the water reservoir assembly further comprises a front and a rear; and

the inlet is disposed closer to the front than the rear of the water reservoir assembly.

10 . The oven of claim 1 , wherein

the water reservoir assembly further comprises (i) a front that is open to the external environment when the water reservoir assembly is in the water supply state and (ii) a rear that faces an opposite direction as the front; and

the inlet is disposed closer to the front of the water reservoir assembly than the rear of the water reservoir assembly.

11 . The oven of claim 1 , wherein

the water reservoir assembly further comprises (i) a front that is open to the external environment when the water reservoir assembly is in the water supply state, (ii) a rear that faces an opposite direction as the front, (iii) a first side and a second side, facing an opposite direction as the first side, that extend between the front and the rear, and (iv) a width between the first side and the second side, the width extending through the inlet; and

the inlet has a width that is parallel to the width of the water reservoir assembly, and the width of the inlet is at least 50% of the width of the water reservoir assembly.

12 . The oven of claim 11 , wherein

the inlet has a length that is orthogonal to the width of the inlet, and the length of the inlet is within a range of from 50% to 150% of the width of the inlet.

13 . The oven of claim 1 , wherein

the fabric comprises layered sheets.

14 . The oven of claim 1 , wherein

the water storage chamber is defined at least in part by a bottom surface; and

the fabric is separated from the bottom surface.

15 . The oven of claim 1 further comprising:

a human-machine interface usable from the external environment,

wherein, the water reservoir assembly further comprises a faceplate,

wherein, in the water supply state, the faceplate is open to and visible from the external environment, and

wherein, in the water supply state, the faceplate is flush with the human-machine interface.
