Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Blowers with multiple discharge departments at the upper portion are vulnerable to external forces, leading to instability and increased flow resistance due to the spacing of these departments, and existing load support structures can exacerbate these issues.
Innovation Solution
A blower design that includes a suction department, a distribution department, and discharge departments with a supporter and ground frame to enhance structural stability by providing a pressure buffer zone and supporting the discharge departments, reducing pressure loss and vortex generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple discharge departments are spaced apart at the upper portion to improve discharge air volume, then discharge air volume is improved, but structural stability deteriorates due to vulnerability to external forces
Solution Approach 1:
A support structure is introduced as an intermediary element between the discharge departments and the housing to counteract external forces. The support structure includes support plates positioned at the rear side of the discharge departments and connected to the housing, providing mechanical stabilization without interfering with the spaced-apart configuration that enables high discharge air volume.
2Productivity
If discharge departments are spaced apart to utilize Coanda effect, then blowing performance is improved, but flow resistance increases due to load support structure
Solution Approach 1:
The support structure is designed with localized support plates that are positioned only at the rear side of the discharge departments and connected to the housing. This localized support provides structural stability while minimizing interference with the overall airflow path, thereby reducing flow resistance compared to comprehensive support structures.
Solution Approach 2:
Instead of providing full support across all surfaces of the discharge departments, the invention applies partial support only at the rear side where external forces primarily act. This partial support action is sufficient to stabilize the discharge departments against external forces while maintaining the spaced-apart configuration for Coanda effect utilization.
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 design improves structural stability and reduces flow resistance by effectively supporting the discharge departments and managing pressure differences, enhancing the blower's ability to maintain efficient air discharge.
Implementation Method 1
a blowing space formed to be spaced at least partly between the plurality of discharge departments facing each other and open at least front and rear, wherein the plurality of discharge departments are connected in parallel to an upper side of the housing with the blowing space therebetween
Implementation Method 2
a blower is provided with a suction port at a lower portion of the blower and a plurality of discharge departments spaced apart from each other at an upper portion of the blower to improve a discharge air volume and use a Coanda effect

AI summary
A blower includes a housing through which air is introduced, a plurality of discharge ports disposed above the housing, each having a discharge port, and facing each other, a blowing space formed to be spaced at least partly between the plurality of discharge departments facing each other and open at least front and rear, a ground disposed on a downstream side of the blowing fan, spaced downward from the plurality of discharge departments, and connected to the housing, and a supporter extending upward from the ground to support the plurality of discharge departments. Accordingly, it is possible to improve blowing performance of the blower by reducing the occurrence of vortex through a pressure buffer zone formed by vertical separation of the ground and the discharge department, and structural stability of the blower can be improved by supporting the discharge department by the supporter and ground disposed inside the housing.
