Cooking Appliance Controller for Automated Residential HVAC Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooking appliances generate heat, steam, and odors during operation, leading to inefficient temperature management and air quality control in residential kitchens, as existing ventilation systems have limited effectiveness and require manual operation.
Innovation Solution
A cooking appliance with a controller that communicates control signals to a residential HVAC system, allowing for proactive temperature management and air quality adjustment based on cooking activities, including the use of sensors and network interfaces to automate HVAC system activation relative to cooking events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If manual hood or vent operation is used, then local air circulation is achieved, but temperature control effectiveness is limited and user convenience deteriorates
Solution Approach 1:
The cooking appliance controller automatically activates the HVAC system based on cooking element operation, eliminating the need for manual user intervention. The system self-monitors cooking element status and self-triggers appropriate HVAC responses to maintain temperature control.
Solution Approach 2:
The controller can activate the HVAC system at a predetermined time before cooking begins or in anticipation of heat generation, proactively preparing the thermal environment before cooking operations commence.
2Temperature
If HVAC system is manually controlled, then system complexity is reduced, but temperature management effectiveness deteriorates
Solution Approach 1:
The cooking appliance controller performs its primary cooking control function while also serving as a HVAC activation controller, enabling one device to perform multiple functions without requiring a separate dedicated control system.
Solution Approach 2:
The controller monitors the operational state of cooking elements and uses this feedback to automatically determine when HVAC system activation is required, creating a closed-loop control system that responds to actual cooking conditions.
3Object-affected harmful factors
If local ventilation is used, then device complexity is minimized, but air quality control effectiveness deteriorates
Solution Approach 1:
The controller acts as an intermediary between the cooking appliance and the HVAC system, translating cooking operational data into appropriate HVAC activation commands that effectively address cooking byproducts through the existing ventilation infrastructure.

AI summary
A cooking appliance includes a housing, and a cooking element disposed in the housing and configured to generate energy for cooking food, and a controller coupled to the cooking element and configured to communicate a control signal to selectively actuate a residential heating, ventilation and/or air conditioning (HVAC) system and/or non-cooking device in connection with cooking food with the cooking element.
