This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,706.

Summary of the Inventive Concept

An enhanced display apparatus for domestic appliances, integrating adjustable air treatment capabilities, optimized air flow, and contaminant detection for improved indoor air quality.

Background and Problem Solved

The original display apparatus for domestic appliances had limitations in terms of air treatment efficiency and adaptability to varying contaminant types. The new inventive concept addresses these limitations by introducing adjustable radiation source devices, optimized air flow rates, and contaminant detection capabilities, ensuring improved indoor air quality and user experience.

Detailed Description of the Inventive Concept

The advanced display apparatus comprises at least one air treatment apparatus integrated into the display, featuring a first radiation source device that can be adjusted to emit electromagnetic radiation of varying wavelengths to accommodate different types of contaminants in the air. The apparatus also includes at least one air flow device to generate an air flow through the air treatment apparatus, with the air flow rate adjustable based on the type of contaminants detected. Additionally, the display apparatus features at least one sensor to detect contaminants in the air and adjust the radiation source device accordingly. The modular design of the display apparatus allows for easy disassembly and maintenance.

Novelty and Inventive Step

The new inventive concept introduces the adjustable radiation source device, optimized air flow rates, and contaminant detection capabilities, which are not present in the original patent. These features provide a significant improvement in air treatment efficiency and adaptability, making the new concept novel and non-obvious compared to the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different types of radiation source devices, such as UV LEDs or lasers, or the integration of additional sensors to detect other environmental parameters. Variations of the concept could also include different display apparatus designs, such as curved or flexible displays, to accommodate various domestic appliance forms and sizes.

Potential Commercial Applications and Market

The advanced display apparatus has significant commercial potential in the domestic appliance industry, particularly in the refrigerator and freezer markets. The improved air treatment capabilities and user experience offered by the new concept can differentiate products and attract environmentally conscious consumers. The modular design also enables easy maintenance and reduces waste, making it an attractive solution for manufacturers and consumers alike.
