Solution Overview
Problem
Sous vide cooking requires precise control of temperature and time, which is challenging with existing cooking apparatuses, often necessitating a separate device for effective sous vide cooking due to difficulties in controlling cooking temperature and time.
Innovation Solution
A cooking apparatus with a housing, heating unit, and temperature sensing device that allows for precise temperature control, featuring a heating unit with radially extending heat-transfer ribs for uniform heating and a door with a gasket for airtight sealing, enabling sous vide cooking within a modular and integrated cooking system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a separate cooking apparatus is used for sous vide cooking, then temperature control precision is improved, but device complexity increases
Solution Approach 1:
The patent combines the sous vide heating unit with a conventional cooking apparatus housing, integrating temperature-controlled water heating functionality into an existing cooking device. The heating unit includes a heater and temperature sensor that work together within the housing to provide precise temperature control for sous vide cooking, eliminating the need for a completely separate apparatus.
Solution Approach 2:
The cooking apparatus is designed to perform multiple cooking functions including conventional cooking and sous vide cooking. The housing can accommodate different cooking modes, and the heating unit can operate in conjunction with existing cooking mechanisms to provide versatile functionality while maintaining precise temperature control for sous vide applications.
2Productivity
If heating is intensified to reduce cooking time, then productivity is improved, but temperature control precision deteriorates
Solution Approach 1:
The heating unit incorporates a temperature sensor that continuously monitors the water temperature and provides feedback to the control system. This closed-loop feedback mechanism allows the heater to adjust its power output dynamically, maintaining precise temperature control even during intensive heating operations. The sensor detects temperature changes and signals the controller to modulate heating intensity, preventing overheating while achieving cooking goals efficiently.

AI summary
A cooking apparatus may include a housing having an open top surface and having a cooking space formed therein; a door provided on a top of the housing to open and close the cooking space; a container inserted into the housing, the container having an open top surface to receive food to be cooked therein; and a heating unit provided in the housing and contacting a bottom surface of the container to heat the container. The heating unit may include a heating unit body defining a support surface that supports the container; a heater provided in the heating unit body; and a rib that extends downward from the heating unit body to prevent water or foreign material from entering between the heating unit and a bottom of the housing.
