Patent Number:AU2021103619A4
Title: A Multi-Purpose Sanitization Chamber
Country:Australia
Priority Date: 25 June 2021
Status: Innovation Patent (Ceased – Non-renewal)
What Is a Multi-Purpose Sanitization Chamber?
A Multi-Purpose Sanitization Chamber is an advanced disinfecting system designed to sanitize a wide range of items — including electronic gadgets, vegetables, groceries, books, clothes, and medical instruments — using a combination of:
- Ultraviolet (UV-C) Light (253.7 nm)
- Heat-Based Deep Sanitization
- Sanitizing Liquid Mist Spray
The chamber integrates these three methods into one controlled, sensor-enabled unit to ensure efficient, safe, and automated disinfection.
Why Was This Patent Developed?
During global health crises such as COVID-19, surface contamination became a major transmission route. Research showed that viruses could survive:
- Up to 3 hours in aerosols
- Up to 3 days on plastic and steel
- Up to 24 hours on cardboard
Traditional cleaning methods were either chemical-heavy or limited in scope. There was a clear need for:
- ✔ A multi-application sanitization system
- ✔ Reduced chemical residue
- ✔ Automated safety control
- ✔ Deep sanitization for medical equipment
This invention addresses those gaps with a triple-layer sanitization mechanism.
How Does the Sanitization Chamber Work?
1. UV-C Light Disinfection
- Uses three Philips TUV T8 8W UV lights
- Positioned at back, left, and right sides
- Interior mirror coating reflects UV light for 360° coverage
- Operates at 253.7 nm wavelength, effective against microorganisms
2. Heat-Based Deep Sanitization
- Two integrated dryers
- Primarily used for medical appliances
- Supports high-temperature microbial reduction
3. Sanitizing Liquid Mist
- Dual mist sprayers
- Applied selectively based on mode
- Suitable for groceries and daily-use items
Smart Safety & Automation Features
The system includes:
- Door Sensor – Stops operation if opened
- Ultrasonic Sensor – Detects object presence
- Door Lock (Auto Locking System)
- Push Button Mode Selection
- Relay Module for Switching Components
- Removable Partition – Converts chamber into dual-section or single large space
- Camera Integration – Object detection support
These features ensure zero UV exposure risk to users and controlled sanitization cycles.
Available Sanitization Modes
| Mode | Use Case | Duration | Method |
|---|---|---|---|
| Mode 1 | Electronic Gadgets | 5 Minutes | UV Only |
| Mode 2 | Daily Items | 10 Minutes | 8 min UV + 2 min Mist |
| Mode 3 | Medical Appliances | 15 Minutes | 8 min UV + 5 min Heat + 2 min Mist |
If the door opens mid-cycle, the process pauses automatically and resumes after closure.
What Makes This Patent Unique?
Unlike traditional UV boxes or heat sterilizers, this invention:
- Combines UV + Heat + Mist in one chamber
- Offers programmable modes
- Provides mirror-based UV amplification
- Includes automatic detection & safety lock
- Supports multiple item categories
- Has removable partition flexibility
It solves major drawbacks of prior systems that relied on single-method disinfection.
Technical Construction
- Outer Box: Bagasse hydraulic press sheet
- Inner Layer: Non-conductive steel
- Inner Surface: Mirror-coated plywood for UV reflection
- Two-section Convertible Design
The design ensures both durability and efficiency.
