Solution Overview

Problem

Air conditioners with ion generators often suffer from reduced charging and collection efficiency due to ions being generated in a small area, leading to contamination of surrounding surfaces and decreased effectiveness in purifying the air.

Innovation Solution

The ion generator is installed at a preset angle within the suction panel, allowing ions to be generated and distributed in a wider area while preventing contamination of the surrounding region, with the angle ranging from 30 to 60 degrees, typically 45 degrees, to optimize ion distribution and collection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the ion generator is disposed horizontally at the center of the filter assembly, then the structure is simple, but ions are generated in a relatively small area reducing charging and collection efficiency

Engineering Contradiction:
Improveion generation areaVSAvoidion generator installation complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The ion generator is disposed at a preset angle (30-60 degrees) relative to the horizontal direction, changing the spatial dimension of ion generation. This angular orientation allows ions to be generated and distributed in a wider area while maintaining structural simplicity, directly resolving the contradiction between ion generation area and device complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Area of stationary object

If the ion generator is disposed perpendicular to the filter assembly, then ions are spread in a wider area, but excess ions attach to wall surfaces causing contamination

Engineering Contradiction:
Improveion distribution areaVSAvoidwall surface contamination
Core Design Contradiction:
Area of stationary objectVSObject-generated harmful factors

Solution Approach 1:

The preset angle parameter (30-60 degrees) is optimized to balance ion distribution area and contamination prevention. This specific angular range allows ions to spread widely while directing them away from wall surfaces, preventing the harmful effect of contamination while maintaining wide distribution.

3Productivity

If the ion generator generates ions in a small area, then the device structure is compact, but charging efficiency and collection efficiency are reduced

Engineering Contradiction:
Improvecharging efficiencyVSAvoidion generator installation space
Core Design Contradiction:
ProductivityVSVolume of stationary object

Solution Approach 1:

By disposing the ion generator at a preset angle rather than horizontally, the same compact installation space produces a wider ion generation area. This dimensional change in orientation allows the system to maintain compact volume while improving charging and collection efficiency through enhanced ion distribution.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

An air conditioner includes a suction panel including a suction grille that defines a suction port configured to receive air, an heat exchanger and a fan that are positioned within the case, and an ion generator disposed in the suction panel and configured to generate ions in the air received through the suction port. The suction panel defines an installation groove recessed from an upper surface of the suction panel and configured to receive the ion generator therein. The ion generator is accommodated inside the installation groove and configured to provide ions toward the upper surface of the suction panel in an upward direction that defines a preset angle with respect to the suction panel.
