摘要： A heated water apparatus which includes a reservoir for retaining a quantity of heated water and a controller for controlling the heated water apparatus. A controllable heater is coupled to the controller and the reservoir for controllably heating the water retained in the reservoir. A water sensor is coupled to the reservoir and to the controller for detecting the presence and absence of a desired quantity of water in the reservoir and providing a signal to the controller. The controller controls a water source which controllably admits water to the reservoir. The controller also controls an outlet valve coupled to the reservoir. The controller operates the inlet valve and the outlet valve to control the flow of water through the outlet valve in response to the presence and absence of water in the reservoir. When the water level is too low, the controller cycles the outlet valve for specific periods of time in order to allow the water level of the reservoir to catch up. During the cycling time, a controller decrements a predetermined flow time in order to dispense a consistent and repeatable quantity of water from the reservoir to a brewing substance.

摘要： A beverage brewing apparatus which includes a substance dispensing device and a brewing device. The brewing apparatus includes a receptacle for receiving a brewing substance from the substance dispensing device, a movable chute positioned between the substance dispensing device and the receptacle, and a water dispensing system operatively associated with the brewing device and selectively communicating with the receptacle for delivering water to a brewing substance retained therein. Additionally, a drive assembly is provided to operatively displace the water dispensing device relative to the receptacle. When the water dispensing device is positioned in communication with the receptacle, the chute is moved out of communication with the receptacle. When the water dispensing device is removed from communication with the receptacle, the chute is placed in communication with the receptacle. The present invention also includes a seal attached to the water dispensing device to seal the water dispensing device while dispensing water to prevent the escape of moisture from the water dispensing device. The apparatus includes a sensor for detecting when a funnel is not present for brewing a beverage or when the funnel has not been recharged and replaced after brewing a beverage and upon initiating a subsequent beverage brewing cycle.

摘要： A coffee grinding apparatus which includes a coffee bean grinding mechanism and a weighing device associated with the grinding mechanism to weigh ground coffee. A receptacle is associated with the weighing device and positioned below the grinding mechanism for receiving ground coffee from the grinding mechanism. The weighing device generates an actual weight signal corresponding to the weight of the ground coffee dispensed into the receptacle. A selecting device is provided to allow a user to select a weight of ground coffee to be produced by the apparatus. A dispensing assembly may be associated with a whole bean hopper, the selecting device and weighing device are coupled to a control circuit which controls the grinding apparatus. The control circuit operates the dispensing assembly and/or the grinding mechanism as a function of a comparison of the actual weight signal and the selected weight signal. As the relationship between the selected weight signal and actual weight signal approaches parity, the control circuit controls to dispensing assembly and/or grinding mechanism to controllably approach the selected weight of ground coffee.

摘要： A temperature control device and method for controlling water temperature for a fill water displacement beverage brewing apparatus. The beverage brewing apparatus includes a heated water reservoir for retaining a predetermined volume of water in a heated state and a thermostatically controlled heating device for heating the water in the heated water reservoir within a predetermined temperature range. The temperature control device includes a brew cycle activation device which automatically overrides the thermostatically controllable heating device for activating the heating device upon initiation of the brew cycle. The method heats fill water introduced into the reservoir regardless of the temperature of the water retained in the heated reservoir to reduce the time required to heat fill water to a desired water temperature.

摘要： Apparatus for melting and heating shortening includes a housing having a top, a bottom and sidewalls; a heating grid mounted in the housing and spaced above the bottom thereof for melting shortening and allowing melted shortening to pass therethrough toward the bottom of the housing. A door is mounted to the housing for introducing a block of shortening onto the heating grid. A bottom heater is mounted adjacent the housing bottom for maintaining the melted shortening at a desired temperature. A control circuit maintains control of the operation of both the heating grid and the bottom heater in a predetermined fashion for initially melting a block of shortening introduced onto the heating grid while substantially preventing smoking of the same, and for maintaining melted shortening at the desired temperature.

摘要： A seed sensor for sensing seeds flowing along a path is provided with an electromagnetic transducer having a movable diaphragm. An arm is secured to a generally peripheral portion of the diaphragm and extends into the seed flow path to be struck at random by the seeds. The arm has a portion operatively engageable with a mid portion of the diaphragm and functions as a mechanical amplifier to actuate the diaphragm when struck by the seeds for producing usable output signals.

摘要： A beverage dispensing system which includes a server, a sensing system coupled to the server for detecting a quantity of beverage retained in the server, a display coupled to the sensing system, and a count-up timer coupled to the system. The display may provide indicia as to the time and/or freshness of the beverage in the server. A method for sensing and displaying a quantity of beverage in a beverage server which can also include a freshness indicator. A resettable timer is incorporated which cannot be reset until at least the sensing system has been physically or operatively uncoupled from the server. The resetting may also require the sensing system to detect an empty server upon recoupling the sensing system with the server. Further, the resetting may also require monitoring a refill function for refill occurring within a predetermined rate parameter or time.

摘要： Disclosed is a conductivity detector assembly for use with a beverage preparation apparatus as well as a hot water dispensing apparatus. The conductivity detecting assembly includes a non-conductive spacer for spacing apart a first conductive portion and a second conductive portion. A conductive path extends through the non-conductive spacer connecting the first and second conductive portions. An exterior surface of the non-conductive spacer is provided in a configuration, for example a generally conical shape with sloped sides, for shedding liquid away from the first conductive portion. A conductive circuit is completed when liquid is retained in the reservoir, the level at which contact can be made between the first conductive portion and a corresponding interior surface or conductive portion of the reservoir. When the conductive circuit is broken the conductivity detector provides a signal to a controller associated with the device indicating that the level has dropped below the level at which the first conductive portion is positioned in the reservoir. Also disclosed are methods for use of the conductivity detector assembly and methods for cleaning a beverage preparation apparatus or a hot water dispenser employing the conductivity detector assembly.
