Abstract

An appliance for automatically brewing a beverage such as coffee, tea or the like comprising a reservoir for receiving a predetermined amount of water, a heating element for heating the water, a container adapted to receive coffee, tea or the like defining a wetting chamber and means for delivering heated water to the wetting chamber. The container includes an outlet port disposed a predetermined distance above the lowest portion of the wetting chamber wherein a predetermined head of water is consistently developed and maintained throughout the brewing cycle.

Claims

1. An appliance for making iced coffee/tea comprising:

a housing,

a reservoir within said housing for holding a predetermined amount of water,

a heating system for heating said water,

a receptacle for receiving brewed heated water,

a container dimensioned to be supported in said receptacle, said container having a chamber adapted to receive coffee, tea or the like and having dispensing means for dispensing brewed, heated water into said receptacle, said dispensing means including overflow means for dispensing said brewed, heated water into said receptacle after said water reaches a certain height in said chamber, and,

means for transferring heated water to said container, said means having orifice means for dispensing heated water into said chamber.

2. An appliance as defined in claim 1 wherein said dispensing means of said container further includes:

drain port means at a low portion of said chamber for selectively communicating with said receptacle, and

valve means operable for opening and closing said drain port to selectively dispense brewed, heated water into said receptacle.

3. An appliance as defined in claim 1 wherein said housing is generally cylindrical in shape, and said means for locating is comprised of a cylindrical recess in said housing, said recess having a radius of curvature generally equal to the radius of curvature of said receptacle.

4. An appliance as defined in claim 1 further comprising means for forcing said heated water through said dispensing means into said chamber.

5. An appliance as defined in claim 4 wherein said means for forcing is comprised of a flow restriction.

6. An appliance according to claim 5 wherein said flow restriction is an orifice.

7. An appliance as defined in claim 1 wherein said overflow means has inlet means a predetermined distance above the bottom of said chamber and outlet means in communication with said receptacle.

8. An appliance as defined in claim 1 wherein said container has a drain port at a low portion of said container, and closure means for selectively opening and closing said drain port, said closure means being normally closed to allow the brewing of water in said chamber and being openable to release the brewed water into said receptacle.

9. An appliance according to claim 8 wherein said closure means has a manually accessible means for opening said closure means.

10. An appliance according to claim 1 wherein said heating system includes means for supplying heated water under pressure to said dispensing orifice, said dispensing orifice injecting said heated water into said chamber.

11. An appliance for automatically brewing a flavorcarrying material such as coffee, tea, or the like comprising:

a reservoir for receiving a predetermined amount of water,

means for heating said water,

a container having a chamber adapted to receive a predetermined maximum amount of said flavor-carrying material therein, said container including an outlet port disposed above the lowest portion of said chamber and above the highest level of said flavor-carrying material, said port communicating with a receptacle below said chamber for receiving brewed liquid, and

means for delivering heated water to said chamber.

12. An appliance as defined in claim 11 further comprising means for forcing said heat water into said chamber.

13. An appliance as defined in claim 11 wherein said means for delivering includes a restrictive nozzle operable to deliver said heated water to said container in pulsed streams.

14. An appliance for automatically brewing coffee, tea or the like comprising:

a reservoir for receiving a predetermined amount of water,

means for heating said water,

a container having a chamber adapted to receive coffee, tea or the like therein, said container including an outlet port disposed a predetermined distance above the lowest portion of said chamber, a drain port at the lowest point in said chamber and valve means operable for opening an closing said drain port, said outlet port communicating with a receptacle below said chamber for receiving brewed liquid, and

means for delivering heated water to said chamber.

15. In an appliance for automatically brewing coffee or tea, said appliance having means for providing heated water for brewing at a predetermined location thereon, a brew funnel for holding tea, coffee or the like for receiving heated water at said predetermined location,

said brew funnel having:

a generally cylindrical shape, a closed lower end and an open upper end defining a chamber for receiving said coffee, tea and water,

a first port located a predetermined distance above the lowest portion of said chamber,

a second port located at the lowest portion of said chamber, said ports operable to drain liquid from said funnel,

a plug associated with said second port movable between a first position closing said second port and a second position opening said port,

means for biasing said plug to said first position, and

lever means on said brew funnel for overcoming said biasing mean to move said plug to said second position.

16. A brew funnel as defined in claim 15 further comprising latch means for maintaining said plug in said second position.

17. An appliance for brewing coffee, tea or the like comprising:

an elongated housing,

a reservoir within said housing for receiving a predetermined amount of water,

a heating unit within said housing for heating said water,

a receptacle for receiving heated water, and

a container dimensioned to be supported over said receptacle, said container having a chamber for receiving coffee, tea or the like, and having dispensing means for dispensing brewed, heated water into said receptacle, said housing and said receptacle being dimensioned such that said receptacle is telescopically received over said housing.
