Abstract

A sous-vide circulator cooker that sounds an audible alarm when the system raises the temperature of the water to a determined temperature. The sous-vide circulator cooker includes temperature sensors, heaters and a pump to circulator temperature controlled fluids. The system also contains a speaker or buzzer that can play alarms or music when the system comes to a predetermined temperature. In at least one embodiment, the sous-vide circulator can also distinguish between self-heating and user-induced temperature changes, and will sound alarms accordingly.

Claims

1. A fluidic temperature control device for sous-vide cooking comprising:

an upper portion including a controller, a display device, and an input device coupled to the controller;

a middle portion connected to the upper portion, the middle portion housing a motor coupled to the controller;

a lower portion connected to the middle portion, the lower portion housing a fluid agitation device coupled to the motor, a heating element coupled to the controller, and the lower portion configured for at least partial immersion in a fluid.

2. The fluidic temperature control device of claim 1, wherein the upper portion contains a speaker that is connected to the controller, wherein the controller is configured to send a signal to the speaker to sound an alarm when a detected temperature of the device rises to a first predetermined temperature.

3. The fluidic temperature control device of claim 2, wherein the controller is further configured to send a signal to the speaker to sound an alarm when a detected temperature of the device cools to a second predetermined temperature.

4. The fluidic temperature control device of claim 3, wherein the cooling to the second predetermined temperature is caused naturally by convective cooling.

5. The fluidic temperature control device of claim 3, wherein the controller is further configured to recognize a user-induced heating and a user-induced cooling, and is further configured to override the signals until the detected temperature begins to normalize, the normalization determined by estimating temperature trends of a fluid within the lower portion.

6. The fluidic temperature control device of claim 1, wherein the upper portion contains a radio transmitter that is connected to the controller, wherein the controller is configured to send a signal to the radio transmitter to send an alert signal to an electronic device in signal communication with the radio transmitter when a detected temperature of the fluidic temperature control device rises to a first predetermined temperature.

7. The fluidic temperature control device of claim 6, wherein the controller is configured to send a signal to the radio transmitter to send an alert signal to the electronic device in signal communication with the radio transmitter when a detected temperature of the fluidic temperature control device cools to a second predetermined temperature.

8. The fluidic temperature control device of claim 7, wherein the cooling to the second predetermined temperature is caused naturally by convective cooling.

9. The fluidic temperature control device of claim 7, wherein the controller is further configured to recognize a user-induced heating and a user-induced cooling, and is further configured to override the signals until the detected temperature begins to normalize, the normalization determined by estimating temperature trends of a fluid within the lower portion.

10. The fluidic temperature control device of claim 1, wherein the upper portion contains a buzzer that is connected to the controller, wherein the controller is configured to send a signal to the buzzer to sound an alarm when a detected temperature of the device rises to a first predetermined temperature.

11. The fluidic temperature control device of claim 10, wherein the controller is further configured to send a signal to the buzzer to sound an alarm when a detected temperature of the device cools to a second predetermined temperature.

12. The fluidic temperature control device of claim 11, wherein the cooling to the second predetermined temperature is caused naturally by convective cooling.

13. The fluidic temperature control device of claim 11, wherein the controller is further configured to recognize a user-induced heating and a user-induced cooling, and is further configured to override the signals until the detected temperature begins to normalize, the normalization determined by estimating temperature trends of a fluid within the lower portion.
