Heat pump module for laundry treatment device and laundry treatment device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heat pump modules in laundry treatment devices face layout difficulties due to space constraints, and the compressor generates vibration and noise, leading to a shortened service life.
Innovation Solution
The heat pump module features a base plate with a recessed surface forming a receiving groove for the compressor, which is embedded and surrounded by a damping sheath, allowing for oblique mounting that optimizes space utilization and reduces vibration and noise through a damping mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the compressor is mounted in a conventional horizontal position, then the structure is simple and easy to manufacture, but the space utilization is poor and the compressor generates excessive vibration and noise
Solution Approach 1:
The compressor is mounted in an oblique position rather than the conventional horizontal orientation. The compressor body is arranged at an angle to the base plate, with its discharge port facing upward and rearward. This dimensional change in mounting orientation optimizes space utilization within the limited appliance compartment while reducing vibration and noise transmission to the base plate.
2Reliability
If the compressor is mounted horizontally on the base plate, then the mounting is simple, but the vibration and noise generated by the compressor directly affect the base plate and reduce service life
Solution Approach 1:
A rubber buffer is introduced as an intermediary element between the compressor and the base plate. The rubber buffer serves as a vibration isolation component that absorbs and dampens the vibrations generated by the compressor during operation, preventing direct transmission to the base plate and reducing noise. This intermediary element protects both the compressor and the base plate from harmful vibrational effects.
Solution Approach 2:
The rubber buffer is pre-installed on the base plate at the mounting position before the compressor is attached. This beforehand cushioning prepares the mounting location with vibration-absorbing material, ensuring that vibration isolation is in place before the compressor begins operation, thereby preventing vibration and noise transmission from the outset.
3Area of stationary object
If the heat pump module components are densely arranged to save space, then the overall device size is reduced, but the layout becomes complex and assembly becomes difficult
Solution Approach 1:
The heat pump module is divided into distinct functional components: the base plate with mounting structures, the compressor with its oblique orientation, the rubber buffer as a separate isolation element, and the discharge port arrangement. This segmentation allows each component to be optimized independently and assembled in a systematic manner, simplifying the manufacturing and assembly process while maintaining compact overall dimensions.
