Air Conditioner Indoor Unit Fastening Structure for Deep Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioner indoor units are difficult to disassemble and clean thoroughly due to complex assembly relationships, leading to potential health risks from dust and bacterial accumulation.
Innovation Solution
The indoor unit design includes a chassis with fastening structures along the up-down direction, allowing for easy disassembly and deep cleaning by rotating the panel and face frame, which are detachably connected, exposing the heat exchanger and air passage components for thorough cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the indoor unit is assembled with fixed assembly relationships among parts (chassis, motor turbine, evaporator, air passage), then the structural stability is improved, but the ease of disassembly and cleaning is worsened
Solution Approach 1:
The indoor unit is divided into multiple detachable modules: the air passage assembly can be separated from the chassis, the motor turbine can be removed from the air passage, and the evaporator can be detached from the air passage. This segmentation allows each component to be independently accessed for cleaning while maintaining structural integrity during operation.
Solution Approach 2:
The patent employs dynamic fastening mechanisms that allow the assembly to transition between a fixed state during operation and a detachable state during maintenance. The air passage assembly is designed to be selectively removable from the chassis, enabling users to disassemble components for thorough cleaning when needed, while maintaining stable assembly during normal operation.
2Ease of operation
If the indoor unit uses simple assembly relationships, then the ease of disassembly is improved, but the reliability of assembly is worsened
Solution Approach 1:
The indoor unit is divided into multiple detachable modules: the air passage assembly can be separated from the chassis, the motor turbine can be removed from the air passage, and the evaporator can be detached from the air passage. This segmentation allows each component to be independently accessed for cleaning while maintaining structural integrity during operation.
Solution Approach 2:
The patent employs dynamic fastening mechanisms that allow the assembly to transition between a fixed state during operation and a detachable state during maintenance. The air passage assembly is designed to be selectively removable from the chassis, enabling users to disassemble components for thorough cleaning when needed, while maintaining stable assembly during normal operation.
3Device complexity
If the indoor unit components are tightly integrated, then the device complexity is reduced, but the ease of repair and maintenance is worsened
Solution Approach 1:
The indoor unit is divided into multiple detachable modules: the air passage assembly can be separated from the chassis, the motor turbine can be removed from the air passage, and the evaporator can be detached from the air passage. This segmentation allows each component to be independently accessed for cleaning while maintaining structural integrity during operation.
Solution Approach 2:
The patent employs dynamic fastening mechanisms that allow the assembly to transition between a fixed state during operation and a detachable state during maintenance. The air passage assembly is designed to be selectively removable from the chassis, enabling users to disassemble components for thorough cleaning when needed, while maintaining stable assembly during normal operation.

AI summary
The present disclosure provides an indoor unit of an air conditioner and an air conditioner. The indoor unit of the air conditioner includes a chassis, a face frame, a panel, a heater exchanger and an air outlet frame. The chassis is extending along an up-down direction, and an upper end of the chassis is provided with a plurality of fastening structures spaced along a left-right direction. The face frame includes an upper support, a lower frame detachably connected to a lower end of the chassis, and two side connectors opposite to each other and between the upper support and the lower frame. A fastening member is arranged on a rear end of the upper support and detachably fastened to the upper end of the chassis. When the face frame is in the assembled state, the fastening member is fastened with the fastening structure to limit the face frame on a front-rear direction; and when a lower end of the face frame is rotated to a preset angle with respect to the upper end of the chassis, the fastening member is disengaged from the fastening structure. The technical solution of the present disclosure can improve the convenience of disassembling the indoor unit, and facilitate deep cleaning of the indoor unit.
