Multi-chamber oven dynamic power redistribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-chamber ovens for baking cannot operate at higher electrical power in one chamber without increasing the total installed rated power, which affects energy consumption and system sizing.
Innovation Solution
The oven features a control unit that dynamically redistributes electrical energy from other chambers to a selected 'superpower' chamber, allowing it to operate at higher power levels by utilizing surplus power from other chambers, without exceeding the total rated power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the total installed rated power of the oven is increased to enable baking at higher electrical power in one chamber, then the superpower baking capability is improved, but the energy consumption and system sizing increase
Solution Approach 1:
The patent implements dynamic power redistribution where the control unit continuously monitors power consumption across multiple chambers and dynamically adjusts power allocation. When one chamber requires superpower for baking, the system dynamically reduces power to other chambers that are not currently in use or require less power, allowing the selected chamber to operate above its pre-assigned power portion without increasing total installed power
Solution Approach 2:
The system changes the power parameter dynamically by allowing temporary exceedance of pre-assigned power portions for selected chambers. The control unit modifies power distribution parameters in real-time based on baking requirements, enabling a chamber to operate at higher power levels when needed while maintaining overall system balance within the total rated power constraint
2Power
If the total installed rated power of the oven is increased to enable baking at higher electrical power in one chamber, then the superpower baking capability is improved, but the system sizing increases
Solution Approach 1:
The control unit implements dynamic power management that allows temporary reallocation of power capacity within existing system limits. By dynamically adjusting power distribution based on real-time chamber requirements, the system enables superpower operation in one chamber without requiring physical expansion of the electrical infrastructure or increase in total installed rated power
3Adaptability or versatility
If electrical energy is redistributed dynamically to a selected chamber, then the baking flexibility is improved, but the control complexity increases
Solution Approach 1:
The control unit continuously monitors power consumption, chamber usage status, and baking requirements to make informed decisions about power redistribution. This feedback mechanism allows the system to automatically adjust power allocation to selected chambers based on real-time conditions, providing baking flexibility while managing control complexity through automated decision-making rather than manual intervention

AI summary
An oven (1) for baking food (2), particularly bakery and confectionery products, comprising a plurality of baking chambers for baking foods (2) and a control unit (11) configured to receive a selection signal (17) of at least one of said chambers, defined as a superpower chamber (3), representative of an operating demand at a superpower value that is greater than the power portion value pre-assigned to such chamber (3). In particular the control unit (11) is configured to: - calculate the difference between the demanded superpower value and the power portion value pre-assigned to the chamber (3); - calculate a total value of instantaneous power unused by the heating means of at least part of the remaining chambers with respect to respective pre-assigned power portions; - divert at least a part of said value of unused instantaneous power towards the heating means for heating said superpower chamber (3).
