Abstract
A pressure regulator and steamer oven for cooking food at low pressure includes heating elements and a cooking cavity having a pool for holding water to be turned into steam. A pressure sensor is disposed in a steam outlet passage connected to the cooking cavity. The pressure sensor is operable to turn off the heating elements when the pressure in the steam outlet passage exceeds a pre-determined level. The pressure sensor may be a float switch monitoring the water level in the steam outlet passage. The condensing steam in the steam outlet conduit may be routed back to the pool in the cooking cavity via an overflow.
