Abstract: A humidifier includes a tub configured to hold a supply of water. The tub includes a tub lid and a tub base adapted to be coupled to the tub lid. The tub further includes a base plate formed of a heat conducting material and adapted to be coupled to the tub base and a seal positioned between the base plate and the tub base. The tub also includes a retaining mechanism with at least one projection that projects from the tub base and is configured to force the base plate against the seal so that the seal is secured against the tub base.

Abstract: A humidifier includes a tub. The tub includes a base plate; a tub base; a seal between the base plate and the tub base; and a latch mechanism that connects the base plate to the tub base so that the base plate is engaged with the seal. The latch mechanism may include an overcenter latch pivotably attached to the tub base and latch tabs formed on the base plate, the overcenter latch engaging the latch tabs in the connected position to connect the base plate to the tub base. The latch mechanism may alternatively include resilient tabs on the tub base, the resilient tabs elastically biasing the base plate toward the tub base upon connection of the base plate to the tub base. The resilient tabs may include tamper evident projections that indicate that the base plate has been disconnected from the tub base. The base plate may be stainless steel and be formed by stamping. The base plate may include a stamped ring. The humidifier further includes a tub lid configured to cover the tub to form a water container.
