초록 ▼

A device that defrosts, warms and/or cooks items such as food in a temperature controlled circulating liquid is described. Embodiments of the device are particularly useful for sous vide cooking that uses relatively low temperatures and long cooking times. The active components including a pump and heater are placed in a self-contained base unit. When the base unit and the liquid-containing vessel or carafe are engaged, the liquid in the carafe is actively circulated by the pump in the base unit. The liquid is also heated as required as it flows through the base unit. Embodiments of the invention that are designed for the consumer can include an easily detachable, lightweight carafe that can be conveniently filled, emptied and cleaned while detached from the base unit. The detachable carafe can be designed with no electrical components so that it can be immersed in water for cleaning.

1. A device for heating food comprising: a removable carafe for holding a fluid in contact with the food, the carafe having a carafe inlet valve and a carafe outlet valve that are biased in a fluid-tight closed position; anda self-contained base unit configured to receive the removable carafe including: first and second valve actuators respectively arranged to mate with and open the carafe inlet valve and the carafe outlet valve when the carafe is positioned in mating contact with the base unit, the mating contact allowing the fluid to circulate between the base unit and the carafe;a pump with an inlet that has a fluid-flow connection to the carafe outlet valve and an outlet that has a fluid-flow connection to the carafe inlet valve when the carafe is positioned in mating contact with the base unit, and wherein the pump circulates fluid through the carafe by drawing fluid from the carafe outlet valve into the base unit and pushing fluid back into the carafe inlet valve when the pump is operating and the fluid-holding carafe is positioned in mating contact with the base unit;an electrically powered heating element positioned in serial fluid-flow connection with the pump to selectively heat the fluid circulating through the base unit and back into the carafe inlet valve;a first temperature sensor positioned for measuring a first temperature of the fluid; anda control system electrically connected to the pump, the heating element, and the first temperature sensor, the control system operating the pump during operation of the device when the carafe is in mating contact with the base unit to circulate the fluid from the carafe through the base unit and back into the carafe, the control system selectively supplying electrical power to the heating element to heat the fluid flowing through the base unit to maintain the first temperature of the fluid near a target temperature. 2. The device of claim 1 further comprising a first pressure sensor positioned to measure a first pressure on an inlet side of the pump and a second pressure sensor positioned to measure a second pressure on an outlet side of the pump, the first and second pressure sensors generating first and second signals that are electrically connected to the control system and the control system determining that the fluid is flowing through the base unit when the difference between first and second signals is greater than a predetermined value. 3. The device of claim 2 wherein the control system switches off electrical power to the heating element if the difference between first and second signals is lower than the predetermined value for more than a predetermined period of time indicating that the fluid is not flowing through the base unit. 4. The device of claim 1 further comprising a differential pressure sensor having a first input positioned on an inlet side of the pump and a second input positioned on an outlet side of the pump, the differential pressure sensor generating a signal representative of a difference between pressures at the first and second inputs, the signal being electrically connected to the control system and the control system detecting the fluid flowing through the base unit based on the signal being greater than a predetermined value. 5. The device of claim 4 wherein the control system switches off electrical power to the heating element if the signal is less than the predetermined value for more than a predetermined period of time indicating that the fluid is not flowing through the base unit. 6. The device of claim 1 wherein the carafe inlet valve is positioned in a first location on a bottom surface of the carafe and the carafe outlet valve is positioned in a second location on the bottom surface of the carafe and the first and second valve actuators are respectively positioned on a top surface of the base unit in mating alignment with the carafe inlet valve and the carafe outlet valve to receive the carafe. 7. The device of claim 1 wherein the first temperature sensor is positioned to measure the fluid temperature on first side of the pump and the device further comprises a second temperature sensor positioned for measuring a second temperature of the fluid flowing through the base unit on an opposite side of the pump relative to the first temperature sensor, the second temperature sensor being electrically connected to the control system, and wherein the control system detects a heater-fault condition when a difference between the fluid temperature on the inlet side of the pump and the fluid temperature on the outlet side of the pump is below a threshold value that is indicative of heater operation. 8. A device for heating food comprising: a removable carafe for holding the food in contact with a fluid, the carafe having a carafe inlet valve and a carafe outlet valve that are biased in a fluid-tight closed position; anda base unit for receiving the carafe, heating the fluid and circulating the fluid, the base unit including a pump, a heater and first and second valve actuators arranged to mate with and open the carafe inlet valve and the carafe outlet valve to establish a circulation path for the fluid from the carafe outlet valve through the pump and heater and back through the carafe inlet valve when the carafe is positioned in mating contact with the base unit and the device is operating. 9. The device of claim 8 wherein the carafe inlet valve is positioned in a first location on a bottom surface of the carafe and the carafe outlet valve is positioned in a second location on the bottom surface of the carafe and the first and second valve actuators are respectively positioned on a top surface of the base unit in mating alignment with the carafe inlet valve and the carafe outlet valve to receive the carafe. 10. The device of claim 8 further comprising: a first temperature sensor positioned for measuring a first temperature of the fluid; anda control system electrically connected to the pump, the heater, and the first temperature sensor, the control system operating the pump during operation of the device when the carafe is in mating contact with the base unit, the control system selectively supplying electrical power to the heater to heat the fluid flowing through the base unit to maintain the first temperature of the fluid near a target temperature.
