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 for the air-conditioner indoor unit is designed with a support body that isolates the temperature-sensing bulb from the filter mesh positioning groove, placing it outside the filter mesh and heat exchanger, and includes air inducing holes to ensure accurate temperature detection, thereby reducing heat and cold radiation impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the temperature-sensing bulb is mounted near the heat exchanger, then the structure is simple and installation is easy, but the temperature detection accuracy deteriorates due to heat radiation from the heat exchanger
Solution Approach 1:
The support body is divided into separate functional zones: a filter mesh positioning groove and a temperature-sensing bulb accommodating groove. The partition wall separates these zones, isolating the temperature-sensing bulb from the filter mesh and heat exchanger area. This segmentation allows the temperature-sensing bulb to be positioned away from heat radiation sources while maintaining structural organization and ease of installation.
Solution Approach 2:
The support body acts as an intermediary structure between the heat exchanger area and the temperature-sensing bulb. By providing a dedicated accommodating groove with partition wall isolation, the support body mediates the spatial relationship, allowing the temperature-sensing bulb to detect ambient temperature accurately without direct exposure to heat radiation from the heat exchanger.
2Measurement precision
If the temperature-sensing bulb is placed outside the filter mesh, then temperature detection accuracy improves, but the device complexity increases
Solution Approach 1:
The support body integrates multiple functions into a single component: it provides structural support, positions the filter mesh, accommodates the temperature-sensing bulb, and isolates the sensing bulb from heat radiation through partition walls. By merging these functions into one integrated support structure, the design achieves accurate temperature detection without significantly increasing overall device complexity.
Solution Approach 2:
The support body serves multiple purposes simultaneously: it acts as a mounting structure for the filter mesh, provides an isolated accommodating groove for the temperature-sensing bulb, and functions as a thermal barrier through its partition walls. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while achieving improved temperature detection accuracy.

Function Achieved in This Case
This solution enhances the accuracy of temperature detection, improving the control and operational reliability of the air-conditioner indoor unit by minimizing radiation interference and ensuring precise temperature measurement.
Implementation Method 1
when a refrigerant having a temperature higher than the ambient temperature passes through the heat exchanger, it may generate heat radiation on the ambient-temperature-sensing bulb

AI summary
A temperature-sensing bulb support for an air-conditioner indoor unit, and an air-conditioner indoor unit are disclosed. The temperature-sensing bulb support 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 configured to accommodate an end frame bar of a filter mesh, and the support body further defines a temperature-sensing bulb accommodating groove configured to accommodate a temperature-sensing bulb. The temperature-sensing bulb accommodating groove is isolated from the filter mesh positioning groove by a partition wall, and the temperature-sensing bulb accommodating groove is located outside the filter mesh positioning groove. 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, aiding in increasing accuracy of control over the air-conditioner indoor unit.
