Solution Overview

Problem

Existing air conditioners that use atomizing units to generate a mist of charged water particles for deodorization often suffer from reduced air flow efficiency due to the placement of the atomizing unit in the air flow path, causing flow resistance.

Innovation Solution

An air conditioner design with a housing that includes a blower, an atomizing unit, and a feed conduit made of flexible material to minimize flow resistance, where the atomizing unit is isolated from the flow channel and the mist is directed through a feed conduit to the air outlet, allowing efficient air flow and deodorization without compromising airflow efficiency.

VSEngineering Contradiction Analysis

1Reliability

If the atomizing unit is disposed in the air flow path to generate mist of charged water particles, then deodorization effect is improved, but air flow efficiency deteriorates due to flow resistance

Engineering Contradiction:
Improvedeodorization effectVSAvoidair flow efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The housing is divided into separate compartments: the air flow channel and the atomizing unit compartment. The partition wall separates these two functional areas, allowing the atomizing unit to be isolated from the main air flow path. This segmentation enables the atomizing unit to generate mist without obstructing the air flow, thus maintaining air flow efficiency while achieving deodorization effect.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A feed conduit acts as an intermediary component to transport the generated mist from the atomizing unit compartment to the air flow channel. The feed conduit penetrates the partition wall and delivers the mist to the air flow without requiring the atomizing unit to be directly in the air flow path, thereby eliminating flow resistance while maintaining mist delivery functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 1:

The housing is divided into separate compartments: the air flow channel and the atomizing unit compartment. The partition wall separates these two functional areas, allowing the atomizing unit to be isolated from the main air flow path. This segmentation enables the atomizing unit to generate mist without obstructing the air flow, thus maintaining air flow efficiency while achieving deodorization effect.

Solution Approach 2:

The partition wall serves multiple functions: it separates the atomizing unit from the air flow channel to maintain air flow efficiency, provides a mounting surface for the feed conduit penetration, and structurally supports the housing configuration. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.

AI summary

An air conditioner has a function of carrying a mist of charged minute water particles on a ventilated air being blown into a room. The air conditioner includes a blower blowing the ventilated air and an atomizing unit configured to be supplied with water and to electrostatically atomize it into the mist of minute charged water particles. A housing of the air conditioner is divided by a partition into a flow channel leading from an air inlet to an air outlet and a compartment accommodating therein the atomizing unit. A feed conduit extends from a feed port of the atomizing unit into a flow channel through the partition to feed the mist to the air being blown out through the air outlet, while the atomizing unit is isolated from the flow channel to minimize flow resistance.
