Abstract

The top surface of an electrode type vaporizer water container has a water inlet covered by a safety cover having an apertured concave portion through which the terminal pins of the electrodes are exposed. A detachable electric power source connector is insertable into the concave portion for engagement with the terminal pins for supplying power to the electrodes. A stopper pin on the connector cooperates with a stopper projection on the container adjacent the terminal pins to prevent the engagement between the connector and pins unless the cover, which as provided with a stopper pin release means, is properly positioned on the container. The engagement of the connector with the terminal pins locks the safety cover in position on the container making it impossible to remove the cover while the connector is so engaged. The safety cover arrangement prevents the supply of water into the container through the inlet with the electrodes electrically energized. The steam nozzle of the vaporizer projects through the cover and includes a convex upper edge which prevents blockage of the nozzle by a planar object laid thereon. The steam nozzle includes a concave part having steam outlets in the bottom wall thereof so arranged that an object dropped into the nozzle will not block the outlets. Projections are provided at the steam outlets to permit condensed water to drain rather than clogging the outlets.

Dependent claims

An electrode type steam vaporizer comprising:

a container body forming a water receptacle, said container body including a surface;
an electrode unit having one end extending into said container body and fittable into an aperture of said surface and another end extending from said container body, said electrode unit including a power source connection external of and adjacent to said body for supplying power to said electrode unit whereby said water in said receptacle is vaporized;
a steam nozzle formed on the other end of said electrode unit;
a removable power source connector adapted to be connected to said power source connection;
a water inlet on said surface;
a cover member covering said surface, said cover including a portion adapted to receive said removable power source connector and to provide access for said power source connector to said power source connection of said electrode unit, wherein said cover member includes an aperture through which said power source connector extends when connected to said power source connection, said cover member and said power source connector cooperating to prevent said cover from being removed from said container body when said power source connector and said power source connection are connected together;
cooperable releasable stopper means on said power source connector and one of said container body surface and said electrode unit for preventing the connection of said power source connector to the power source connection of said electrode unit;
and
a stopper means releasing means on said portion of said cover member, said releasing means adapted to contact and release said releasable stopper means when said power source connector is inserted into said portion of said cover and said cover member is enclosing said surface.
