DETAILED DESCRIPTION

Various embodiments of the disclosure are discussed in detail below. While specific implementations are discussed, it should be understood that this is done for illustration purposes only. A person skilled in the relevant art will recognize that other components and configurations may be used without departing from the scope of the disclosure.

Several definitions that apply throughout this document will now be presented. “Circulating” means agitating, blending or mixing of one or more fluids. Hence a “circulator” is a device which can be configured to agitate, blend or mix a fluid. Fluids will be understood to comprise liquids. “Coupled” is defined as connected, whether directly or indirectly through intervening components and is not necessarily limited to physical connections. Coupled devices are devices which are in signal communication with one another. “Connected” means directly connected or indirectly connected.

Broadly speaking, this disclosure relates to sous-vide circulator cookers for cooking food.

In at least one embodiment, a sous-vide circulator cooker has a speaker or other suitable alert device connected to the controller in the control head to sound audible alarms when the bath fluid has reached cooking temperature.

In at least one embodiment, the speaker can also be a single tone buzzer.
