Ceiling-embedded type indoor unit for air conditioner, and air conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing ceiling concealed indoor units for air-conditioning apparatus face challenges in achieving accurate assembly of auxiliary decorative panels to body decorative panels, leading to potential design spoilage due to level differences and assembly inaccuracies.
Innovation Solution
Incorporating a body decorative panel with pairs of guide ribs that restrict the movement of auxiliary decorative panel rails in the width direction, ensuring precise coupling and alignment between the panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking bracket is securely mounted in a ceiling space to fix the auxiliary decorative panel to the body decorative panel, then the auxiliary decorative panel can be fixed, but it becomes difficult to ensure assembly accuracy and avoid design being spoiled
Solution Approach 1:
The patent introduces guide ribs as an intermediary component between the body decorative panel and auxiliary decorative panel. These guide ribs protrude from the body decorative panel and fit into grooves on the auxiliary decorative panel, serving as a mediating structure that simultaneously provides guidance for precise positioning and constraints for reliable fixing, thereby resolving the contradiction between assembly accuracy and fixing reliability
Solution Approach 2:
The patent replaces the traditional locking bracket mechanical system with a guide rib and groove system. Instead of using complex locking brackets that require ceiling space mounting, the invention uses simple protruding guide ribs that fit into corresponding grooves, substituting a complex mechanical fixing system with a simpler geometric fitting system that achieves both precision and reliability
2Power
If the indoor unit size is increased to replace an existing unit, then the cooling/heating capacity is improved, but the new indoor unit may differ in size from the ceiling opening, resulting in excess clearance that spoils design
Solution Approach 1:
The patent divides the decorative panel system into modular components: a body decorative panel that covers the main indoor unit and auxiliary decorative panels that can be added to fill excess clearance spaces. This segmentation allows the decorative system to be adapted to different indoor unit sizes while maintaining a complete, flush appearance against the ceiling
Solution Approach 2:
The patent creates a dynamic decorative panel system where auxiliary decorative panels can be selectively added or removed based on the specific installation scenario. This dynamic configuration allows the same body decorative panel to adapt to different ceiling openings and indoor unit sizes, maintaining design appearance across various power capacities

AI summary
A ceiling concealed indoor unit and an air-conditioning apparatus equipped therewith includes a body; and a body decorative panel installed below the body, in which the body decorative panel includes a pair of guide ribs disposed to be opposite to each other and adapted to accept passage of a rail of an auxiliary decorative panel coupled to the body decorative panel.
