A47J 3102

US Classification:

137132

Abstract:

A valve assembly particularly usable with a coffee brewing basket being automatically dripless during the coffee brewing cycle which includes a valve body member having a head section and a main section threadedly engageable through the lower opening in the brewing basket by threaded engagement with a siphon cap thereabove. The siphon cap includes a plurality of slots for admitting brewed coffee therethrough for siphon feeding and a main tube extending downwardly through a main flow aperture defined in the upper portion thereof to facilitate the main avenue of flow of brewed coffee downwardly through the brew basket opening. Engagement between the main valve body member and the siphon cap is achieved by threaded engagement and a truncated section is included for defining a siphon flow path adjacent the threaded engaging sections.

Abstract:

A splash retaining assembly usable with a coffeemaker which has a spray head and a brew basket mountable directly therebelow within basket support guides. The spray retaining assembly includes a main plate extending horizontally and having a horizontal section with a main central aperture defined therein. Vertical sections at the laterally outermost edges of horizontal section extend downwardly and a lower lip extends inwardly from the lowermost end of the vertical sections in order to define with the vertical section and the horizontal section a longitudinal slot. In this manner the main plate is adapted to be positioned in the basket support guides to provide the splash plate and also to define longitudinal slots adapted to receive placement of the brew basket therein for normal operation thereof. A shield plate is secured to the main plate and has an outer section which is secured to the horizontal section of the main plate and an upper section which is generally arcuate having a downwardly facing concave surface and is adapted to be in close proximity with the spray head of the coffeemaker for shielding the coffeemaker from hot coffee vapors rising from the brew basket. The splash retaining assembly is maintained in place by a main biasing device for holding the main plate within the basket support guides and by a basket biasing means for retaining a brew basket within the longitudinal slots defined by the main plate.
