  • Patent number: 5132520
    Abstract: A food storage cabinet, preferably with a food toaster mounted thereon, for storing toasted foods in a heated, humidified state. The cabinet has an upper chamber and a lower chamber with supply and return ducts connecting the atmospheres of the two chambers. Heat and humidity sensors in the return duct emit signals to a controller indicative of the temperature and humidity in the upper chamber, where food is stored, so that the temperature and humidity can be regulated and maintained against a specified temperature and humidity. Additional heat for the upper chamber is generated by a strip heater attached to the ceiling of the lower chamber, providing heat and also evaporating condensate forming on the floor of the upper chamber. Additional humidity is provided by a spray of a water mist onto a heating element in the lower chamber. A slightly angled door in the top of the upper chamber allows access to stored foods and rolls shut when not being held open.
