Abstract

The steam generation device includes a steam generation container, a lid portion, and a water level sensor. The steam generation container heats water. The lid portion covers an upper opening portion of the steam generation container. The water level sensor detects a water level in the steam generation container. The water level sensor includes a first electrode rod, a second electrode rod, a bracket, and silicone rubber. The first electrode rod is fixed to the lid portion in a state where the first electrode rod penetrates the lid portion. The bracket is configured integrally with the second electrode rod, inserted into an opening portion provided in the lid portion, and fixed to a peripheral edge portion of the opening portion. The silicone rubber is interposed between the bracket and the lid portion.

First claim

The invention claimed is:

1 . A steam generation device comprising:
a steam generation container configured to heat water; a lid portion covering an upper opening portion of the steam generation container; and a water level sensor configured to detect a water level in the steam generation container, wherein the water level sensor includes:
a first electrode rod fixed to the lid portion in a state that the first electrode rod penetrates the lid portion,
a second electrode rod,
a bracket configured integrally with the second electrode rod, inserted into an opening portion provided in the lid portion, and fixed to a peripheral edge portion of the opening portion, and
an interposition component interposed between the bracket and the lid portion, and wherein the opening portion in which the second electrode rod is fixed is provided on a side surface of the lid portion other than a top surface of the lid portion and other than a surface on which the first electrode rod is fixed.

2 . The steam generation device according to claim 1 ,
wherein the steam generation container includes a surrounding space and an open space, the first electrode rod is disposed in a water level detection chamber cover that forms a water level detection chamber in the surrounding space, and the second electrode rod is not surrounded by the water level detection chamber cover and is disposed in the open space.

3 . The steam generation device according to claim 1 ,
wherein the interposition component is formed of silicone rubber.

4 . A heating cooking apparatus comprising:
the steam generation device according to claim 1 ; and a heating chamber to which steam from the steam generation device is supplied.

5 . The steam generation device according to claim 2 ,
wherein a through hole is provided near a bottom of the water level detection chamber cover.
