Definitions

  • This invention generally relates to a beverage maker and method of making beverage by passing hot water through a dry ingredient, such as ground coffee or tea and, specifically, to a semiautomatic beverage maker of this type and method of using same.
  • an automatic beverage maker in which an electric motor is used to open and close a dispenser valve respectively in response to actuation of a start switch and lapse of a preselected brew period measured by a timer.
  • a stop switch is provided to cause the motor to move the valve to a closed position before automatic closure at the lapse of the brew period.
  • Other automatic beverage makers are known in which the dispenser valve is automatically caused to both open and close through selective energization and de-energization of an electromechanical valve drive mechanism in response to manual switch actuation. Examples of such automatic beverage makers are shown in United States patents 3,608,471 issued September 28, 1971 to Martin and 3,998,144 issued December 21, 1976, to Curtis.
  • a dispenser valve assembly for selectively blocking and enabling removal through a dispenser outlet hole of liquid within a supply tank of a beverage maker at a uniform rate on a semiautomatic basis in which the dispenser valve is opened manually but is automatically returned to a closed position automatically at the end of a preselected time period, or early by manual means.
  • the semiautomatic dispenser valve comprises a valve assembly with a valve member movable between an open position in which liquid in the supply tank flows through the valve and into the beverage container and a closed position in which liquid does not flow through the valve.
  • the beverage maker also has means for manually moving the valve member to the open position, means for producing a return force to automatically return the movable valve member to the closed position, and means for holding the movable valve member against return to the closed position for a preselected time period after manual movement of the movable member to the open position.
  • the movable member is automatically returned to the open position by the return force producing means upon release thereof by said holding means.
  • the safety valve control assembly comprises an actuator for controlling the operation of the dispenser valve, a locking member, and means responsive to movement of the actuator for movement of the locking member between a locked position in which removal of the ingredient holder from the preselected safe location is prevented when the dispenser valve is open, and an unlocked position in which removal of the ingredient holder from the preselected safe position is enabled when the dispenser valve is closed.
  • It is a further object to provide a method of semiautomatically controlling the passage of liquid to a container from a supply tank of a beverage maker comprising the steps of manually moving a valve member from a closed position to an open position in which liquid is passed to the container, holding the valve member in the open position against automatic return thereof to the closed position, releasing the hold of the valve member, and automatically returning the valve member to the closed position in response to the hold thereon being released.
  • Fig. lA is a front view of a portion of the semiautomatic beverage maker of the present invention showing the upper housing, an ingredient holder, the dispenser valve actuator and holder locking member in an open position;
  • Fig. IB is a partially sectional side view of the semiautomatic coffee maker of Fig. lA showing the dispenser valve, the water supply tank, ingredient holder and dispenser valve actuator when the dispenser valve is in a closed position;
  • Fig. 1C is a front sectional view of the semiautomatic beverage maker of Fig. lA in which the timer, dispenser valve opening means and means for holding the dispenser valve in an open position are shown;
  • Fig.2A is a front view of a portion of the semiautomatic beverage maker of the present invention showing the upper housing, an ingredient holder, the dispenser valve actuator and holder locking member in an open position;
  • Fig. 2B is a partially sectional side view of the semiautomatic coffee maker of Fig. 2A showing the dispenser valve, the water supply tank, ingredient holder and dispenser valve actuator when the dispenser valve is in an open, brew position;
  • Fig. 2c is front sectional view of the semiautomatic beverage maker of Fig. 2A in which the timer, dispenser valve opening means and means for holding the dispenser valve in an open position are shown;
  • Fig. 3 is a functional block diagram of the preferred embodiment of control circuit for the semiautomatic beverage maker of Figs. lA, IB, 1C, 2A, 2B and 2C.
  • a manual dispenser valve actuator 12 When in the stop condition, a manual dispenser valve actuator 12 is in a relatively elevated position next to the word "STOP". As best seen in Fig. IB, the manual dispenser valve actuator 12 is mechanically linked to a dispenser valve tube 14 such that when the manual valve actuator 12 is in the "STOP" position, as shown in Fig. lA, the inlet valve opening 14A is elevated above a preselected surface level 16 of water within a supply tank 18 to a closed position. In this closed position, no water is allowed to enter the inlet end 14A and, thus, no water enters the tube 14 to be dispensed from the outlet valve opening 14B.
  • the mechanical linkage includes an elongate linkage rod 20 connected for rotation with the actuator arm 12 at one end and mounted for axial rotating movement at its other end in a cylindrical bore 22 within the side of an upstanding drain chamber 24.
  • the end adjacent the actuator arm 12 is also mounted for axial rotary motion within a bearing hole through a front panel plate 26.
  • the horizontal section of the dispenser valve tube 14 is also mounted for rotary axial movement at a rotary, sealed bearing 28 at a side of the drain chamber 24 opposite the linkage rod 20 at one end and at a cylindrical rotary bearing 30 in the side of the supply tank 18 at the other end 14B.
  • the axis of rotation of the dispenser valve tube 14 coincides with that of the linkage rod 20.
  • the ends of the linkage rod 20 at the dispenser valve tube 14 adjacent the drain chamber 24 are interconnected behind the drain chamber 24 by means of a C-shaped clamp assembly.
  • the C-shaped clamp assembly includes an L-shaped arm 32 having a vertical section connected to linkage rod 20 by means of a screw 34 at the free end and a horizontal section which extends behind the drain chamber 24 to connect with one end of a plate 36.
  • the other end of the plate 36 is connected to the dispenser valve tube 14 adjacent the drain chamber 24. Accordingly, when the actuator arm 12 rotates, the linkage rod C-shaped clamp assembly and the dispenser valve tube will rotate with it.
  • the ingredient holder 38 is mounted at its edges for sliding movement along L-shaped channels 40 to and from a fully engaged position, shown by broken line 38, at which it receives hot water from the drain chamber 24 and possibly also from a beverage strength control by-pass valve 42, and funnels and directs the hot beverage through a drain 44 in its bottom to a relatively small opening of an urn (not shown) located directly beneath the drain 44 when it is in the fully engaged position shown by broken line 44*. Removal of the ingredient holder 38 is required after each brew cycle in order to remove the old filter and depleted dry ingredient. None prevents such removal when the actuator arm 12 is in the stop position, as shown.
  • the brew basket 38 should not be fully removed or even partially removed, as shown in solid line in Fig. IB during the brew cycle, for in that event hot scalding water f om the drain chamber 24 and by-pass valve 42 will not be directed into the open mouth of the urn (not shown) and can splash on the operator, counters and floors causing possible injury and damage.
  • the object of the invention is achieved in part through virtue of the fact that when the actuator arm 12 is mounted in a position relative to the ingredient holder 38 and mounting channels 40 such that its distal end 12' extends below the channels 40 in a position to block sliding removal of the ingredient holder 38 from the fully engaged safe position shown in Fig. 2B whenever the actuator 12 is moved to the reltively lower, or vertical "BREW" position shown in Fig. 2A. While it is preferred to directly block brew basket removal in this direct mechanical fashion, it is also contemplated to block removal of the brew basket indirectly with an electromagnet latch which is automatically moved into blocked position whenever the brew cycle is in process either by actuation of a start switch or manually, as here.
  • the dispenser valve tube 14 when the dispenser valve tube 14 is rotated to the open position with the inlet opening 14A beneath the surface 16 of the hot water in supply tank 18 and the actuator arm 12 is in the "BREW" position as shown, the ingredient holder 38 cannot be removed.
  • the hot water which flows through tube 14, out of outlet 14B and through the drain chamber 24 and overflow valve 42 can only drain into the ingredient holder 38 and from therethrough the drain 44 into the urn (not shown).
  • the actuator arm In order to remove the ingredient holder 38, the actuator arm must first be raised to the "STOP" position in which the inlet end 14A of the diagram valve tube 14 is elevated above the preselected surface level 16.
  • the surface level 16 is maintained by means of an inlet valve (not shown) which is controlled in response to a level sensor 46 to maintain the level 16 constant.
  • the preferred embodiment of the control unit for the semiautomatic beverage maker 10 includes a timer switch 48, a coil spring, or spring, 50, also seen in Figs. IB and 2B, a start switch 52, and a solenoid or electromagnet 53 and a start switch actuator arm 54 providing a mechanical linkage 56* between the dispenser valve, or manual brew control valve, 14 and the start switch 52.
  • the electromagnet 53 also has a mechanical linkage 56' to the manual brew control valve 14 through means of an armature head 56 carred at the end of start switch actuator 54, as best illustrated in Fig. 2 ⁇
  • the spring 50 also has a linkage 50 1 to the dispenser valve.
  • the armature head 56 causes the normally open start switch 52 to close when it as manually moved to the "BREW” position.
  • This causes the normally open timer switch 48 to close to apply 110 VAC power to energize electromagnet 53.
  • the energized electromagnet 53 holds the actuator arm 54 in position to keep the start switch 52 closed.
  • the timer After a preselected time period for brewing, approximately four minutes, after actuation of the start switch, the timer causes the timer switch 48 to revert to its normally open condition. This de-energizes the electromagnet 53 which releases its hold through armature head 56 to the start switch actuator arm 54 which is then returned by the spring 50 to the "STOP" position and the start switch is then deactuated.
  • a C-9, C-Frame AC Power Solenoid made by Deltrol Controls Division of Deltrol Corp. as published at page 24 of their 1988 catalog was used for the electromagnet 53.
  • a Solid- State Cube Timer Interval, Q-4 Series made by National Controls and published at page 8 of their 1988 catalog was used for the timer switch 48.
  • the start switch 52 was a Miniature, Light Force, E Series switch made by Cherry Electrical Products and published at page 18 of their 1988 catalog.
  • the coil spring was selected to have more than sufficient strength to return the armature head to the "STOP > ⁇ ' position.
