Door body device and refrigeration apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional refrigerators with built-in decorative panels interfere with cupboards during door opening, affecting aesthetics and user experience.
Innovation Solution
A door body device with a slide door mechanism that includes a box door, a cupboard door, and a traction assembly, allowing the cupboard door to slide relative to the box door during opening, avoiding interference with cupboards while maintaining aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a decorative panel is added at the outside of the refrigerator door to enhance coordination and aesthetics, then the appearance coordination and aesthetics are improved, but the decorative panel interferes with the cupboard during the door opening process
Solution Approach 1:
The patent applies the dynamics principle by making the cupboard door movable rather than fixed. The slide door mechanism allows the cupboard door to automatically slide along the width direction of the box door during the opening process, transitioning from a static blocking position to a dynamic clear path, thereby eliminating interference while preserving the decorative panel's aesthetic function
Solution Approach 2:
The patent introduces a slide door mechanism as an intermediary component between the box door and the cupboard door. This mechanism includes a traction assembly and a slide door assembly that mediates the interaction between opening the box door and moving the cupboard door, enabling coordinated movement that prevents interference while maintaining appearance coordination
2Object-generated harmful factors
If the door opening angle is reduced to avoid interference between the decorative panel and the cupboard, then the interference problem is avoided, but the user experience is affected
Solution Approach 1:
By making the cupboard door dynamically movable through the slide door mechanism, the system eliminates the need to limit the box door opening angle. The cupboard door automatically slides out of the way during opening, allowing full door opening capability and maintaining excellent user experience while avoiding interference
3Object-generated harmful factors
If the distance between the cupboard and the side of the refrigerator is increased to avoid interference, then the interference problem is avoided, but the coordination and aesthetics are affected
Solution Approach 1:
The patent uses the dynamics principle to allow the cupboard door to move during opening, which enables the cupboard to be positioned closer to the refrigerator side while still avoiding interference. The slide door mechanism dynamically adjusts the cupboard door position, maintaining tight integration and aesthetic coordination without requiring increased clearance

AI summary
The present application relates to the technical field of refrigeration apparatuses. Provided are a door body device and a refrigeration apparatus, the door body device comprising a refrigerator door, a cabinet door and a sliding door mechanism. The refrigerator door having a thickness of 18-60 mm is rotatably connected to a refrigerator body by means of a hinge and is adapted to open or close a storage space of the refrigerator body; the cabinet door having a thickness of 12-26 mm is slidably arranged on an outer side of the refrigerator door; and the sliding door mechanism comprises a traction assembly and a sliding door assembly which are connected to each other, wherein the traction assembly is arranged on the hinge, the sliding door assembly is arranged on the refrigerator door and connected to the cabinet door, and the traction assembly is configured, during opening or closing of the refrigerator door, to drive the sliding door assembly to act, so as to drive the cabinet door to move in the direction of width relative to the refrigerator door. Thus, when the refrigerator door rotates relative to the refrigerator body, the sliding door assembly can be driven by the traction assembly to cause the cabinet door to move relative to the refrigerator door, thereby preventing the cabinet door from interfering with a cabinet when the refrigeration apparatus is embedded in the cabinet.
