Solution Overview

Problem

The existing air conditioner indoor units face challenges in simplifying the electrical wire arrangement, particularly due to the confusion and space requirements when both electrical wires for the cleaning assembly and wind deflector are arranged on the chassis.

Innovation Solution

The electrical wires for the cleaning assembly and electric control box are arranged along the cleaning module and filter screen rail module, minimizing the space occupied on the chassis and simplifying the wiring structure by using clamping line members and electrical wire penetrating grooves to secure and route the wires effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If electrical wires for cleaning assembly and wind deflector are both arranged on the chassis, then connectivity is achieved, but wire arrangement complexity and space requirements increase

Engineering Contradiction:
Improveelectrical wire connectivityVSAvoidwire arrangement complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides the electrical wire routing into separate paths: wires for the cleaning assembly are arranged along the cleaning module and filter screen rail module, while wires for the wind deflector remain on the chassis. This segmentation prevents confusion and reduces arrangement complexity while maintaining all necessary connections.

Inventive Principle:
Principle #1Segmentation

2Reliability

If electrical wires for cleaning assembly are arranged on the chassis, then connectivity is achieved, but the space required on the chassis increases

Engineering Contradiction:
Improveelectrical wire connectivityVSAvoidchassis space
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The patent relocates the cleaning assembly electrical wires from the chassis plane to a different spatial path along the cleaning module and filter screen rail module. This dimensional change in wire routing eliminates the need for additional chassis space while preserving electrical connectivity.

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

3Device complexity

If electrical wires are arranged along cleaning module and filter screen rail module, then wire arrangement complexity is reduced, but wire routing path length changes

Engineering Contradiction:
Improvewiring structure simplicityVSAvoidelectrical wire length
Core Design Contradiction:
Device complexityVSLength of moving object

Solution Approach 1:

The patent optimizes wire routing by following the local structure of the cleaning module and filter screen rail module. The wires are arranged to utilize the existing structural pathways and spacing of these components, achieving simple wiring configuration while controlling wire length through efficient use of available space along the cleaning assembly path.

Inventive Principle:
Principle #3Local quality

AI summary

Disclosed are an indoor unit and an air conditioner. The indoor unit includes: an electric control box; a cleaning assembly including: a filter screen rail module; and a cleaning module configured to drive a filter screen to move on the filter screen rail module to clean the filter screen, and including an electrical wire connecting end. And an electrical wire arranged on the cleaning module and the filter screen rail module. One end of the electrical wire is connected to the electrical wire connecting end. And the other end of the electrical wire is connected to the electric control box. The technical solution of the present disclosure is used for arranging the electrical wires for connecting the cleaning assembly and the electric control box on the cleaning module and the filter screen rail module. Thereby the wiring space of the chassis of the indoor unit isn't occupied. And the electrical wire arrangement of the cleaning assembly is simplified.
