Abstract

A steam generator includes: a water storage chamber which stores water therein, at least one heating portion which heats water in the water storage chamber to generate steam, a water supply device which supplies the water storage chamber with water, a steam spout port which spouts the steam generated in the water storage chamber therethrough, and a plurality of fins positioned below the steam spout port in a steam-generating direction and spaced from one another, wherein a first distance between the plurality of fins differs from a second distance between an inner wall side surface of the water storage chamber and the fins.

First claim

What is claimed is:

1. A steam generator comprising:
a water storage chamber which stores water therein;
at least one heating portion which heats water in the water storage chamber to generate steam;
a water supply device which supplies the water storage chamber with water;
a controller that controls the at least one heating portion and the water supply device;
a steam spout port which spouts the steam generated in the water storage chamber therethrough; and
a plurality of fins below the steam spout port in a steam-generating direction and spaced from one another;
wherein the plurality of fins protrude from an inner lateral surface of the water storage chamber and are in contact with the at least one heating portion,
wherein a first distance between the plurality of fins in a central portion of the plurality of fins differs from a second distance between fins at end sides of the plurality of fins and at an inner wall side surface of the water storage chamber and the fins, and
wherein the controller issues a water supply instruction to the water supply device to perform water supply and activates the at least one heating portion to generate steam, and then steam generated between the plurality of fins is discharged from the steam spout port above the plurality of fins.

2. The steam generator according to claim 1 , wherein the heating portion comprises a heater, and at least one of the fins crosses the heater.

3. The steam generator according to claim 2 , wherein the first distance is smaller than the second distance.

4. The steam generator according to claim 1 , further comprising a recess in an inner wall of the water storage chamber at a location facing the heating portion.

5. A heating cooker provided with the steam generator according to claim 1 .

6. The steam generator according to claim 2 , further comprising a recess in an inner wall of the water storage chamber at a location facing the heating portion.

7. The steam generator according to claim 3 , further comprising a recess in an inner wall of the water storage chamber at a location facing the heating portion.

8. A heating cooker provided with the steam generator according to claim 2 .

9. A heating cooker provided with the steam generator according to claim 3 .

10. A heating cooker provided with the steam generator according to claim 4 .

11. A heating cooker provided with the steam generator according to claim 6 .

12. A heating cooker provided with the steam generator according to claim 7 .
