Solution Overview

Problem

Dew condensation water from refrigerant pipes above the compressor can infiltrate and deteriorate the soundproof sheet, causing damage.

Innovation Solution

A cover member with a flat main body and hole portions for pipes is provided on the compressor's upper surface, preventing direct contact of dew condensation water with the soundproof sheet and being supported by the pipes, thus suppressing infiltration and displacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a cover member is provided on the upper surface of the compressor to prevent dew condensation water infiltration, then the soundproof sheet is protected from deterioration, but the device complexity increases

Engineering Contradiction:
Improveprotection of soundproof sheetVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

A cover member is introduced as an intermediary component between the dew condensation water source and the soundproof sheet. This cover member acts as a protective barrier that prevents direct contact between the harmful water and the vulnerable soundproof material, thereby protecting the soundproof sheet from deterioration while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The cover member is installed in advance on the upper surface of the compressor before dew condensation water can infiltrate the soundproof sheet. This preliminary protective measure ensures that when dew condensation occurs during operation, the soundproof sheet is already protected and cannot be damaged by water infiltration.

Inventive Principle:
Principle #10Preliminary action

2Stability of the object's composition

If the cover member is supported by the pipe to prevent position displacement, then the cover member is retained at predetermined position, but the ease of manufacture decreases

Engineering Contradiction:
Improveposition stabilityVSAvoidmanufacturing simplicity
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The pipe serves a dual function: it performs its primary function of connecting to the compressor and additionally provides support for the cover member. By utilizing the existing pipe structure to hold the cover member at the predetermined position, the design avoids the need for separate support components, thereby maintaining ease of manufacture while achieving position stability.

Inventive Principle:
Principle #25Self-service

AI summary

The present disclosure provides a cover member for a compressor that can suppress infiltration of dew condensation water to a soundproof sheet of the compressor and can suppress deterioration of the soundproof sheet. The cover member in the present disclosure is a waterproof member that covers an upper surface of the compressor, and the cover member includes a main body with an approximately flat shape, in which the main body includes a hole portion through which a pipe is inserted, the pipe being connected to the compressor. In this way, by providing the cover member on an upper surface of the compressor, direct contact with the compressor, of dew condensation water dripping down from a refrigerant pipe positioned above the compressor can be suppressed with the cover.
