Ceiling-Mounted Blower Rail Structure for Easy AC Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ceiling-mounted air conditioners face difficulties in maintenance due to limited space and configuration issues, particularly when dealing with dual-axis motors or multiple blower units, which hinder efficient attachment and detachment of blower units and impact the deformation and vibration characteristics of the top plate.
Innovation Solution
A ceiling-mounted air conditioner design featuring a unit body with a bent support member that integrates the blower unit, including parallel rail members on the top plate and an aperture for sliding insertion and removal, allowing for efficient maintenance and reinforcement of the top plate without increasing its thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the fan casing is fixed to the unit body and only the impeller and motor are slidingly inserted through support rails, then the structure is simple for single blower units, but it cannot accommodate dual-axis motors or multiple blower units
Solution Approach 1:
The blower unit is divided into separable components (motor, impeller, support member) that can be independently assembled and disassembled. The support member is segmented into a partition plate portion and a support plate portion connected by a bent connection, allowing flexible configuration for different blower unit types including dual-axis motors and multiple units.
2Ease of operation
If support fittings are mounted on the base and fan motor base is inserted from above, then fan motor can be detachably mounted, but predetermined space above support fittings is required which increases unit body size
Solution Approach 1:
Instead of inserting the fan motor base from above onto support fittings mounted on the base, the invention inverts the approach by mounting the support member with integrated support plate on the top plate, and slidingly inserting the blower unit horizontally along rail members. This eliminates the need for vertical clearance above the base.
3Device complexity
If the blower unit is directly mounted to the top plate, then the structure is simplified, but the top plate experiences deformation and vibration
Solution Approach 1:
The invention introduces rail members as intermediary elements between the top plate and the blower unit. These rail members serve as both guides for sliding insertion and reinforcement structures that distribute loads, preventing direct mounting-induced deformation and vibration of the top plate while maintaining structural simplicity.
4Ease of repair
If maintenance is performed through an inspection port in the ceiling, then components can be accessed, but the operation is difficult and time-consuming
Solution Approach 1:
The invention makes the blower unit dynamically removable rather than fixed. The support member with bent connection and sliding insertion along rail members enables the blower unit to be easily extracted through the inspection port and reinserted, transforming maintenance from a time-consuming disassembly operation to a simple plug-and-play process.

AI summary
Provided is a ceiling-mounted air conditioner that facilitates an attachment and detachment operation of a blower unit relative to a unit body regardless of the number of blower units and realizes improvement of deformation and vibration characteristics of a top plate of the unit body. In the ceiling-mounted air conditioner, the blower subunits (11A, 11B) are integrated with the support member (20A, 20B) bent substantially at a right angle, one surfaces of which are configured to be partition plates (22A, 22B) for partitioning an inside of the unit body (2) into an inlet region and an outlet region, and the other surfaces of which are configured to be support plates (21A, 21B) for supporting fans (18A, 18B, 18C) and motors (19A, 19B) of the blower subunits (11A, 11B). The blower subunits (11A, 11B) are slidingly inserted between a pair of the rail members installed in parallel on an inner surface of a top plate from one end to the other end of the top plate of the unit body (2) from the aperture (26) provided in one side surface of the unit body (2), so as to be mounted into the unit body (2) through the support members (20A, 208).
