Air Regulating Device for Indoor and Outdoor Air Circulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional window fans can only introduce outdoor fresh air and are limited to summer use, while household heaters can only provide heating and not air circulation, leading to poor indoor air circulation in closed environments.
Innovation Solution
An air regulating device that can function as both a fan and a heater, equipped with a casing assembly, outdoor fresh air regulator, fan assembly, and heating assembly, allowing for indoor and outdoor air circulation by introducing outdoor fresh air and heating it when needed, and can be installed in various locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a window fan is used to introduce outdoor fresh air into the room, then air circulation is improved, but heating function is lost and the device can only be used in summertime
Solution Approach 1:
The patent combines a fan assembly and a heating assembly into a single integrated device housed within the same casing. The controller enables the device to switch between fan-only mode, heating-only mode, and combined mode, allowing it to function as both a window fan for air circulation and a heater for warming the room, thereby resolving the seasonal limitation
2Temperature
If household heaters are used to provide warm air in the room, then heating function is improved, but air circulation capability is lost
Solution Approach 1:
The patent integrates both heating and air circulation functions into one device. The fan assembly can operate independently to provide air circulation, the heating assembly can operate independently to provide warmth, or both can work together to heat and circulate air simultaneously, eliminating the need for separate devices
3Productivity
If multiple window fans are installed to achieve different air volumes in the room, then air circulation is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The patent incorporates a controllable fan assembly that can adjust its operating speed and air volume output. The controller enables dynamic adjustment of fan speed to achieve different air circulation volumes, eliminating the need to install multiple fans with fixed capacities
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively addresses poor indoor air circulation by introducing outdoor fresh air and providing heating, offering a versatile solution for different user needs and environments, being compact and portable for use on floors, countertops, or windows.
Implementation Method 1
a fan assembly comprising a first fan wheel or a second fan wheel... wherein the first/second fan wheel is laterally supported in the first/second fan wheel housing
Implementation Method 2
a heating assembly supported at an air tunnel outlet of the first/second air tunnel and electrically connected to a control switch

AI summary
An air regulating device includes a casing assembly, an outdoor fresh air regulator, a fan assembly, and a heating assembly. The casing assembly includes a front casing having a first fresh air inlet and an air outlet, and a rear casing has a second fresh air inlet. The outdoor fresh air regulator includes a front damper gate coupled at the front casing to selectively open and close the first fresh air inlet, and a rear damper gate coupled at the rear casing to selectively open and close the second fresh air inlet. The fan assembly is arranged to suck outdoor fresh air from the second fresh air inlet to the air outlet. The heating assembly is disposed within the air tunnel for heating up the outdoor fresh air before entering into the indoor side at the air outlet.
