Water Tank Drawer Locking Mechanism for Stable Air Treatment Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air conditioner indoor units face reduced efficiency due to dust particles blocking airflow and the difficulty in cleaning and replacing filter screens and adsorbents, which can lead to secondary air pollution.
Innovation Solution
An air treatment device with a safety locking member that allows the water tank drawer to be securely locked or unlocked, preventing accidental displacement and improving operational safety by changing the relative position between the locking member and cooperation protrusions on the water tank drawer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the water tank drawer is made movable for easy maintenance and cleaning, then the ease of operation is improved, but the reliability deteriorates due to risk of accidental displacement
Solution Approach 1:
The locking member is designed to be rotatable between a locking position and an unlocking position, allowing the system to dynamically switch between locked and unlocked states. This enables the water tank drawer to be securely locked during operation but easily accessible when needed for maintenance, resolving the contradiction between stability and ease of maintenance.
Solution Approach 2:
The safety locking member changes the positional parameter of the locking member relative to the cooperation protrusions. When rotated to the locking position, the locking member engages with the cooperation protrusions to prevent displacement; when rotated to the unlocking position, engagement is released, allowing easy removal and installation of the water tank drawer.
2Object-affected harmful factors
If filter screens and adsorbents are used for air purification, then the air treatment function is improved, but the productivity deteriorates due to reduced air intake amount
Solution Approach 1:
The patent employs filter screens and solid adsorbent materials with porous structures that allow air to pass through while capturing dust particles and harmful substances. The porous structure provides sufficient airflow passages that maintain air intake amount while achieving effective air purification, resolving the contradiction between purification effectiveness and productivity.

AI summary
An air treatment device and an air conditioner indoor unit are provided. The air treatment device has an air outlet frame of a purification air duct. The air outlet frame has a ventilation hole and a cooperation hole. A water tank drawer is moveable on the air outlet frame and has two spaced-apart cooperation protrusions on a bottom wall thereof. A safety locking member of the air treatment device has a rotating shaft and a locking member. The rotating shaft is rotatable in the cooperation hole to switch the locking member between a locking position of the locking member and a movement-permitting position of the locking member. At the locking position, the locking member engages the cooperation protrusions to prevent the displacement of the cooperation protrusions. At the movement-permitting position, the locking member is located between the two cooperation protrusions to avoid engagement with the cooperation protrusions.
