Outdoor unit for central air conditioner and central air conditioner having same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing outdoor units for central air conditioners require time-consuming and labor-intensive maintenance due to the large number of bolts used for panel fixation, which increases operational costs, especially in regions with high labor costs.
Innovation Solution
A pivotally and detachably connected panel system using a pivot structure with a base and pivot seat, allowing for easy opening and closing of the outdoor unit, reducing manual labor and maintenance time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the panel is fixed by bolts, then the panel connection is reliable and stable, but the maintenance operation becomes time-consuming and labor-intensive
Solution Approach 1:
The connection structure is segmented into a pivot shaft fixed on the unit body and a pivot seat on the panel, allowing the panel to be divided into removable and fixed portions. This enables the panel to be quickly detached for maintenance while maintaining reliable connection during operation.
Solution Approach 2:
The panel connection transitions from a static bolted connection to a dynamic pivot connection that allows both rotational movement for access and secure fixation during operation. The pivot structure enables the panel to be easily rotated open for maintenance and securely closed during operation.
2Stability of the object's composition
If the panel is fixed by bolts, then the panel structure is stable, but the ease of operation during maintenance deteriorates
Solution Approach 1:
The panel is segmented into a fixed portion attached to the unit body and a removable portion connected via pivot structure. This segmentation allows the removable portion to be easily operated during maintenance while the fixed portion maintains structural stability.
Solution Approach 2:
The pivot structure acts as an intermediary between the fixed unit body and the removable panel portion. It provides a stable connection point that enables easy operation of the panel while maintaining overall structural stability.
3Strength
If multiple bolts are used to fix the panel, then the panel connection is secure, but the device complexity increases
Solution Approach 1:
Multiple bolts are extracted and replaced by a single pivot shaft and pivot seat structure. This simplifies the connection structure while maintaining secure attachment, reducing the number of fastening elements from multiple bolts to a unified pivot mechanism.
Solution Approach 2:
Multiple bolt connections are merged into a single integrated pivot structure. The pivot shaft and pivot seat combine the functions of multiple fasteners into one unified connection mechanism, reducing complexity while maintaining connection strength.

AI summary
An outdoor unit for a central air conditioner and a central air conditioner having the same are provided. The outdoor unit includes a unit body and at least One panel. One side of the unit body is open, and the panel is arranged on the side of the unit body to open and close the unit body. One end of the panel is pivotally and detachably connected to the unit body through a pivot structure. The pivot structure includes a base provided on the unit body and a pivot seat provided on the panel. A top of the base has a pivot shaft spaced apart from the unit body and extending upward, and the pivot seat is provided with a pivot hole having an open bottom and configured to be detachably fitted with the pivot shaft.
