Sous-vide cooker

A sous-vide cooker for use with water, comprising

• a cooking chamber comprising:
• a chamber body having a bottom interior surface;
• a multi-function lid;
• and
• a passive water circulator;
• a heating system comprising:
• a heating unit;
• a plurality of temperature sensors not in direct contact with any water inside the chamber body;
• a proportional-integral-derivative (PID) controller;
• and
• a control panel;
• and
• a housing that houses the cooking chamber and the heating system,
• wherein said PID controller uses a temperature correction algorithm that implements a temperature conversion factor so that the temperatures measured by the plurality of temperature sensors reflect actual water temperature in the chamber body, and wherein the heating system heats the chamber body and the PID controller controls the temperature using the plurality of temperature sensors and the heating unit, and wherein the plurality of temperature sensors are vertically spaced on the outside of the chamber body.

A sous-vide cooker for use with water, comprising

• a cooking chamber comprising:
• a chamber body having exterior surfaces and interior surfaces;
• a lid comprising an heat insulating layer and a heat reflective layer;
• and
• a water circulating plate located in the proximity of a bottom interior surface of the chamber body;
• a heating system comprising:
• a heating unit that is in contact with the chamber body at a bottom exterior surface of the chamber body;
• one or more temperature sensors not in direct contact with any water inside the chamber body and positioned exteriorly to the chamber body;
• a proportional-integral-derivative (PID) controller;
• and
• a control panel;
• a housing having a vented side wall;
• and
• a base having a vented bottom plate,
• wherein said PID controller uses a temperature correction algorithm that implements a temperature conversion factor so that the temperatures measured by the one or more temperature sensors reflect actual water temperature in the chamber body, wherein said PID controls the heating unit and causes the heating unit to heat the chamber body, and wherein when the chamber body is filled with water, the water is maintained at a set temperature with a variation from the set temperature that is equal to or less than 0.5° C.
