Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The ambient-temperature-sensing bulb in air-conditioners is often affected by heat radiation from the heat exchanger, leading to inaccurate temperature detection and reduced control accuracy and reliability of the air-conditioning system.
Innovation Solution
A temperature-sensing bulb support that isolates the temperature-sensing bulb from the filter mesh positioning groove using a partition wall, placing it outside the filter mesh and providing air inducing holes to ensure accurate temperature detection, thereby reducing the impact of heat radiation and improving control accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the temperature-sensing bulb is mounted near the heat exchanger, then it can detect temperature close to the heat exchanger, but it is affected by heat radiation from the heat exchanger causing inaccurate ambient temperature detection
Solution Approach 1:
The support structure is divided into separate functional zones: a filter mesh positioning groove and a temperature-sensing bulb accommodating groove, separated by a partition wall. This segmentation isolates the temperature-sensing bulb from the filter mesh area and heat exchanger radiation while maintaining structural integrity.
Solution Approach 2:
A partition wall is introduced as an intermediary element between the filter mesh positioning groove and the temperature-sensing bulb accommodating groove. This partition wall blocks heat radiation from the heat exchanger from reaching the temperature-sensing bulb, while still allowing the system to function as intended.
2Measurement precision
If the temperature-sensing bulb is placed outside the filter mesh, then heat radiation impact is reduced, but the structural complexity increases due to partition wall and groove design
Solution Approach 1:
The support structure combines multiple functions into a single integrated component: it provides mechanical support for the filter mesh, positions the temperature-sensing bulb, and blocks heat radiation through the partition wall. This merging reduces the need for separate components and simplifies the overall structure.
Solution Approach 2:
The support structure serves multiple purposes simultaneously: it acts as a mounting bracket for the filter mesh, creates a protected accommodation space for the temperature-sensing bulb, and functions as a thermal barrier through its partition wall. This multi-functionality reduces device complexity while achieving the desired isolation.

AI summary
A temperature-sensing bulb support (10) for an air-conditioner indoor unit, and an air-conditioner indoor unit are disclosed. The temperature-sensing bulb support (10) includes: a support body. The support body is adapted to be fixed to a housing of the air-conditioner indoor unit. The support body defines a filter mesh positioning groove (1) configured to accommodate an end frame bar (30) of a filter mesh, and the support body further defines a temperature-sensing bulb accommodating groove (2) configured to accommodate a temperature-sensing bulb. The temperature-sensing bulb accommodating groove (2) is isolated from the filter mesh positioning groove (1) by a partition wall, and the temperature-sensing bulb accommodating groove (2) is located outside the filter mesh positioning groove (1). The temperature-sensing bulb is placed outside the filter mesh while protecting the temperature-sensing bulb, such that the temperature-sensing bulb can detect ambient temperature more accurately, thereby aiding in increasing accuracy of control over the air-conditioner indoor unit and operational reliability of the air-conditioner indoor unit, and saving power
