Solution Overview
Problem
Traditional refrigerators with built-in decorative panels experience interference between the refrigerator door and the cupboard during opening, affecting user experience and aesthetics.
Innovation Solution
A door body device with a box door connected via a single-axis hinge and a slide door mechanism, including a traction assembly and slide door assembly, allowing the cupboard door to move relative to the box door, preventing interference with the cupboard.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a decorative panel is added at an outside of the refrigerator door to ensure coordination and aesthetics with the cupboard, then the appearance coordination is improved, but the decorative panel interferes with the cupboard during door opening
Solution Approach 1:
The patent applies the dynamics principle by transforming the static decorative panel into a dynamic slide door assembly that can move relative to the box door. The slide door mechanism allows the decorative panel to slide along the width direction of the box door when the box door opens, preventing interference with the cupboard while maintaining appearance coordination when closed.
Solution Approach 2:
The patent segments the door structure into multiple independent components: the box door, the slide door assembly, and the decorative panel. This segmentation allows the decorative panel to be independently controlled to slide away from the cupboard during door opening, resolving the interference issue while maintaining aesthetic coordination when the door is closed.
2Area of stationary object
If the gap between the refrigerator and the cupboard is kept small to save space, then space utilization is improved, but the decorative panel still interferes with the cupboard during door opening
Solution Approach 1:
The slide door mechanism enables the decorative panel to dynamically adjust its position during door opening. When the box door opens, the traction assembly drives the slide door assembly to slide along the width direction, creating temporary clearance between the decorative panel and the cupboard. This allows the refrigerator to be placed close to the cupboard for space savings while avoiding interference during operation.
3Object-affected harmful factors
If a slide door mechanism is added to allow the cupboard door to move relative to the box door, then interference with the cupboard is avoided, but the device complexity increases
Solution Approach 1:
The patent introduces a slide door assembly as an intermediary component between the box door and the decorative panel. This intermediary element carries the decorative panel and allows it to slide relative to the box door through a relatively simple traction assembly, avoiding the need for complex mechanisms while still preventing interference with the cupboard.
Solution Approach 2:
The slide door mechanism is designed to be driven by the door opening motion itself. The traction assembly utilizes the movement of the box door to automatically drive the slide door assembly to slide, eliminating the need for additional motors or complex control systems. The mechanism serves itself by converting the door opening action into the sliding motion of the decorative panel.

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 comprises: a refrigerator door, which is adapted to rotatably connect to a refrigerator body by means of a single-axis hinge and is adapted to open or close a storage space of the refrigerator body; a cabinet door, which is a wooden cabinet door slidably arranged on an outer side of the refrigerator door; and a sliding door mechanism, which comprises a traction assembly and a sliding door assembly connected to each other, wherein the traction assembly is arranged on a front surface of the refrigerator body, 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, such that, when the refrigeration apparatus is embedded in a cabinet, while the coordination is ensured, the cabinet door is prevented from interfering with the cabinet.
