Vehicle Air Conditioner Ionizer Mounting Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle air conditioning systems face difficulties in easily mounting and removing the ionizer due to limited space, making maintenance challenging, and are prone to electrical connections between discharge electrodes caused by moisture, leading to spark noise.
Innovation Solution
An ionizer mounting structure that allows sliding movement from a demounting position to a mounting position on the air conditioning case, using a guide means and fixing means to secure the ionizer, preventing electrical connections by positioning discharge electrodes above the moisture flow and using a seal member to prevent foreign materials from entering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ionizer is fixedly secured to the air conditioning case using screws through joint pieces, then the ionizer is firmly attached, but it becomes very difficult to remove and replace the ionizer due to limited space
Solution Approach 1:
The ionizer is divided into separable components: the main body with joint pieces and the discharge electrodes. The joint pieces can be detached from the air conditioning case, allowing the ionizer to be removed in segments rather than as a single fixed unit, thus facilitating maintenance while maintaining secure attachment during operation
Solution Approach 2:
The mounting structure transitions from a static fixed state to a dynamic removable state. The joint pieces are designed to be securely fastened during operation but can be easily detached when needed, allowing the system to adapt between these two states based on operational requirements
2Volume of moving object
If the first and second discharge electrodes are arranged one above the other to save space, then the ionizer structure is compact, but moisture condensed flows from the upper electrode to the lower electrode causing electrical connection and spark noise
Solution Approach 1:
The discharge electrodes are arranged in a horizontal configuration rather than vertically stacked. This dimensional change in electrode arrangement prevents moisture flow from causing electrical connection between electrodes while still achieving compact space utilization through lateral positioning instead of vertical stacking
Solution Approach 2:
The moisture flow path is redirected away from the electrode arrangement. By positioning electrodes horizontally and using the air conditioning case structure, the natural moisture flow direction is utilized to bypass the electrodes rather than bridge them, converting the harmful moisture flow into a non-interfering path

AI summary
The present invention relates to an ionizer mounting structure for a vehicle air conditioning system. The air conditioning system includes an air conditioning case having an internal passageway and an ionizer for generating negative ions and positive ions within the internal passageway. The air conditioning case has a discharge electrode insertion hole and the ionizer has a plurality of discharge electrodes extending into the internal passageway through the discharge electrode insertion hole. The ionizer mounting structure includes a mounting and demounting structure for allowing the ionizer to be mounted to the air conditioning case through sliding movement from a demounting position on a passenger room side to a mounting position above the air conditioning case and for allowing the ionizer to be demounted from the air conditioning case through sliding movement from the mounting position to the demounting position.
