Heat Pump Mounting Box With Drawable Lint Filter Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing heat pump dryers or washer-dryers suffer from poor sealability between the flock filter unit and air inlets/outlets, leading to air loss and flock accumulation due to a drawable air guide structure, making it difficult to maintain effective drying performance and clean the flock filter unit.
Innovation Solution
A heat pump mounting box design featuring a base with an air suction port and an air passage guide plate that defines a direct communication path for drying air, combined with a drawably mounted flock filter mesh assembly, which enhances connection tightness and facilitates easy cleaning by preventing air loss and flock accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the flock filter unit is fixed on the air guide structure, then the connection tightness is improved, but the ease of cleaning deteriorates
Solution Approach 1:
The flock filter unit is designed with a drawable mounting mechanism that allows it to be fixed in position during operation to maintain connection tightness, but can be easily drawn out for cleaning. This dynamic mounting solution resolves the contradiction by enabling the filter unit to transition between a fixed state (for reliability) and a removable state (for ease of cleaning).
2Ease of manufacture
If the air guide structure is drawn, then the ease of assembly is improved, but the connection tightness deteriorates
Solution Approach 1:
The air guide structure is segmented into multiple parts that can be assembled through drawing operations, facilitating ease of assembly. The segmentation allows the structure to be constructed in sections while maintaining overall connection tightness through proper joining mechanisms at the interfaces between segments.
3Stability of the object's composition
If the flock filter unit is fixed on the air guide structure, then the structural stability is improved, but the flock accumulation worsens
Solution Approach 1:
The drawable mounting mechanism enables the flock filter unit to be dynamically adjusted or removed, preventing prolonged operation in a fixed position that would lead to flock accumulation. The unit can be periodically drawn out for cleaning while maintaining structural stability during normal operation.

AI summary
A heat pump mounting box for a heat pump dryer or washer-dryer, and a heat pump dryer or washer-dryer having the same are provided. The heat pump mounting box includes a base provided with an air suction port and a two-device mounting chamber; an air passage guide plate mounted on the base and defining, together with the base, an air guide passage that has a drying air inlet in communication with the air suction port and a drying air outlet in communication with the two-device mounting chamber; and a flock filter mesh assembly drawably mounted on at least one of the base and the air passage guide plate and located at the drying air outlet. The heat pump mounting box according to the present invention has good connection tightness and is easy to clean, thereby being less likely to cause air quantity loss and flock accumulation.
