Refrigerator Turnover Beam Guide Mechanism for Airtight Seal Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In side-by-side refrigerators, the turnover beam's incorrect angle during closure can cause collisions between the turnover beam and door body, leading to damage and compromising the airtight seal, which affects heat preservation and energy efficiency.
Innovation Solution
The design incorporates a guide seat with a guide groove and a limiting block that guides the turnover beam's movement, ensuring proper alignment and sealing, even in cases of user misoperation, by allowing the guide block to pivot and reset the limiting block to maintain the seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the turnover beam is pivotally connected to the door body to seal the gap, then the sealing effect is improved, but the turnover beam may collide with the door body when at incorrect angles, causing damage
Solution Approach 1:
The guide groove acts as an intermediary structure between the guide block and the door body. It guides the turnover beam's movement path, ensuring the guide block enters and exits the groove at correct angles, thereby preventing direct collision between the turnover beam and door body while maintaining sealing effectiveness.
2Ease of operation
If the guide groove is open at the bottom with a front side opening, then the guide block can enter and exit freely, but the turnover beam may be mispositioned during closure, affecting sealing
Solution Approach 1:
The guide groove is pre-positioned on the door body at the correct location and orientation. The limiting block is pre-installed within the guide groove to define the entry and exit boundaries. This preliminary arrangement ensures that when the guide block moves through the open front side opening, it automatically follows the correct path and maintains proper alignment, preventing mispositioning during closure.
3Adaptability or versatility
If the limiting block is rotatably connected to guide the guide block, then the turnover beam can be reset after misoperation, but the structure becomes more complex
Solution Approach 1:
The limiting block is designed to be rotatable rather than fixed, allowing it to dynamically adjust its position. When the guide block enters the guide groove at an incorrect angle, the limiting block can rotate to accommodate the misalignment, then guide the guide block into the correct position. This dynamic capability provides reset functionality without requiring complex additional mechanisms, as the rotation itself is the simple means of adaptation.

AI summary
A refrigerator is provided, which includes a refrigerator body, a pair of door bodies, a turnover beam, a guide seat and a limiting block. The turnover beam is pivotally connected with one of the pair of door bodies, and the turnover beam includes a turnover beam body. The guide seat includes a guide seat body and a guide groove disposed in the guide seat body. The limiting block is rotatably connected with the guide seat body. When at least a portion of the guide block presses the limiting block through the front side opening of the guide groove, the limiting block is configured to pivot and exit the guide groove, and after the guide block enters the guide groove, the limiting block is configured to be reset by pivoting to limit the guide block.
