Rotating Radial Space Heater for Uniform Room Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional space heaters, including convection and forced air models, suffer from inefficiencies such as temperature stratification, uneven heating, and the creation of hot and cold zones, which result in wasted energy and delayed heating relief for users.
Innovation Solution
A portable electric space heater with 360° rotation that directs a radially outward flow of heated air stream, combining a minimized heating element and blower with a rotational engine to achieve rapid and even heating by projecting heated air outward and rotating it continuously around a perpendicular axis, reducing stratification and zone formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional convection space heaters use natural convection to disperse heated air, then the heated air rises to the ceiling causing temperature stratification, but the user in the lower portion of the room does not receive immediate heating relief
Solution Approach 1:
The patent applies a rotating air stream deflector that dynamically changes the direction of the heated air stream throughout the room. The deflector rotates on a vertical axis to distribute heated air radially outward in all directions, preventing temperature stratification and delivering immediate heating relief to users regardless of their position in the room.
2Area of stationary object
If conventional forced air space heaters use simultaneous continuous 360° heat discharge, then the heat output area increases, but the velocity of the heated air stream is lowered causing the device to act like a conventional convection space heater
Solution Approach 1:
The patent segments the 360° heat discharge into sequential directional streams by using a rotating air stream deflector. Instead of discharging air simultaneously in all directions, the deflector rotates to create sequential high-velocity streams that penetrate different areas of the room over time, maintaining both wide coverage and high velocity.
3Productivity
If the volume and velocity of the heated air stream are increased, then the heating effectiveness improves, but the draft effect induced into the room creates a cooling sensation in areas not in the initial discharge area
Solution Approach 1:
The rotating air stream deflector dynamically redirects high-velocity heated air streams to continuously cover different areas of the room. This prevents draft-induced cooling sensations by ensuring that all areas receive periodic high-velocity heated air, eliminating cold spots that would otherwise be created by stationary discharge patterns.
