Bottom shell assembly and air conditioner having same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing air conditioner assembly process is labor-intensive and time-consuming, particularly for the evaporator component, as it requires manual handling and overturning of the bottom housing, hindering automatic assembly.
Innovation Solution
A bottom housing assembly with a pipe-layout structure and latching assembly that allows for the convenient and automatic assembly of gas-liquid pipes between the electric box and the base, featuring a pipe groove and connecting column for pipe passage and locking mechanisms for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the pipe passing mode requires manual overturning of the bottom housing during assembly, then the evaporator refrigerant inlet and outlet pipes can be assembled in the pipe groove, but the labor intensity increases and automatic assembly is hindered
Solution Approach 1:
The patent inverts the traditional assembly sequence by pre-assembling the evaporator component with the pipe groove cover before installing the entire assembly onto the base. This reversal eliminates the need for manual overturning operations and enables automatic assembly, as the evaporator is now installed in an upright position from the beginning rather than requiring flipping to access the pipe groove.
Solution Approach 2:
The patent applies preliminary action by pre-assembling the evaporator component with the pipe groove cover integrated as a unified structure before installation. The pipe groove cover is pre-formed with notches for gas-liquid pipes, and the evaporator is pre-positioned within this integrated structure, allowing the entire assembly to be installed automatically without manual intervention during the final assembly step.
2Ease of manufacture
If manual overturning of the bottom housing is required during assembly, then the pipe groove can be accessed for assembling evaporator pipes, but time and labor are consumed
Solution Approach 1:
The patent eliminates assembly time loss by pre-assembling the evaporator component with the pipe groove cover integrated before final installation. All pipe connections and structural elements are prepared in advance, so that when the entire assembly is installed onto the base, no additional manual operations or time-consuming adjustments are required.
Solution Approach 2:
The patent merges the evaporator component and the pipe groove cover into a single integrated assembly. The pipe groove cover is designed as an integral part of the evaporator structure, with notches formed directly on the cover for gas-liquid pipe passages. This merging eliminates the need for separate assembly steps and reduces overall assembly time significantly.
3Ease of operation
If the electric box is detachably installed on the base through connecting columns, then the structure becomes modular and easier to assemble, but the connection stability must be maintained
Solution Approach 1:
The patent segments the air conditioner structure into modular components: the base, the electric box, and the evaporator assembly with pipe groove cover. These segmented modules are connected through connecting columns that allow for easy assembly and disassembly while maintaining structural integrity. The modular design enables independent manufacturing and testing of each component before final assembly.
Solution Approach 2:
The connecting columns serve as intermediary elements between the base and the electric box. These columns provide a standardized connection interface that ensures both ease of assembly and connection stability. The connecting columns are designed with precise dimensions and mounting features that guarantee proper alignment and secure attachment, maintaining structural stability while enabling modular assembly.
