Indoor unit for air conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing indoor air conditioner units with rear-facing suction ports pose challenges in filter installation and maintenance due to spatial limitations, requiring users to access the filters from the rear, which is inconvenient and complicates the installation of multiple filter types.
Innovation Solution
The indoor air conditioner unit features a filter mounting system with a mobile member that allows the filter module to be moved to a forward position, enabling easy installation and removal of filters from the front, using dual links and a driving device to change the filter module's position in response to user commands, facilitating the use of multiple filters while maintaining a slim design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the suction port is formed at the rear side of the cabinet, then the air intake function is achieved, but the filter installation and maintenance becomes inconvenient due to spatial limitations
Solution Approach 1:
The filter module is made movable through a mobile member mechanism that allows it to move between a first position (aligned with the suction port at the rear) and a second position (exposed at the front). This dynamic positioning enables the filter to be accessed from the front for installation and maintenance while maintaining its functional position at the rear for air filtration, thus resolving the contradiction between ease of operation and cabinet structure.
2Adaptability or versatility
If multiple types of filters are installed at the rear suction port, then air cleaning performance is improved, but the device complexity increases due to multiple coupled structures
Solution Approach 1:
The filter module is designed as a universal, integrated structure that can accommodate multiple types of filters (pre-filter, HEPA filter, carbon filter, etc.) in a single standardized unit. This multi-functional filter module replaces the need for multiple separate filter structures, allowing various filter types to be installed while maintaining a simple and unified mounting structure that attaches to the mobile member, thus resolving the contradiction between adaptability and device complexity.
3Reliability
If the filter module is disposed at the rear suction port, then the air filtration function is achieved, but the thickness of the filter module increases
Solution Approach 1:
The filter module utilizes the depth dimension of the cabinet by being disposed at the rear suction port, allowing it to extend backward into the cabinet interior. This dimensional arrangement enables the filter module to achieve sufficient thickness for effective air filtration while keeping the front profile of the cabinet compact, as the filter's thickness is accommodated in the rearward direction rather than increasing the overall front-to-back depth of the cabinet.

AI summary
An indoor unit for an air conditioner including: a cabinet assembly forming an external appearance of the indoor unit and having a suction port formed in a rear surface of the cabinet; a filter module movably disposed in rear of the cabinet assembly; a filter module mounted to the filter mounting member and filtering foreign substances in air flowing into the suction port; a mobile member connected to the filter mounting member and moving a position of the filter mounting member; a driving device pressing the mobile member to change the position of the filter mounting member; and a controller configured to, in response to receiving a control command to change the position of the filter mounting member, operate the driving device that presses the mobile member.
