Mobile Company Indoor Restroom

The indoor restroom designs of some mobile communication units in Beijing integrate technology and humanization, featuring the following characteristics:

1. Air Quality Management: Precise Control of Odor Diffusion
The restroom employs negative pressure gradient control technology, adjusting airflow to maintain slightly lower internal pressure compared to the external corridor, creating an “odor-locking” effect that prevents odors from spreading to public areas. Each stall is equipped with an induction-based exhaust system that automatically activates when a user enters, capturing and expelling odors through localized airflow. This dual strategy ensures overall air quality while providing enhanced treatment for high-frequency use areas, effectively addressing the issue of lingering odors in traditional restrooms.

2. Surface Cleaning and Maintenance: Contactless Technology Reduces Cross-Infection Risks
High-touch surfaces (such as faucets and door handles) utilize infrared sensors and ToF (Time of Flight) sensors for contactless operation. For example, faucets automatically release water upon infrared detection, and door handles may feature automatic sliding or sensor-based designs, minimizing direct hand contact and thereby reducing the risk of microbial cross-transmission. This design is particularly crucial during pandemics or in settings with high public health standards, demonstrating how technology supports health and safety.

3. Water-Saving System Design: Graywater Recycling for Resource Circulation
The restroom incorporates graywater recycling, where wastewater from sinks is initially filtered and disinfected before being reused for toilet flushing. This design reduces freshwater consumption through immediate water reuse, making it especially suitable for settings with high occupancy and water usage. For instance, if each person uses 0.5 liters of water per handwashing session, with an average of 100 daily users, approximately 50 liters of water can be saved daily. Over time, this significantly lowers operational costs and environmental impact.

4. Humanized Details: Balancing Functionality and Comfort

• Privacy and Ventilation Balance: The gaps between stall doors and floors are precisely calculated to meet ventilation needs while blocking lines of sight, protecting user privacy.
• Convenient Storage Design: Small shelves or hooks are installed inside stalls, with positions determined by ergonomic calculations, facilitating the placement of items like phones and bags to prevent loss or contamination.
• Lighting Optimization: The mirror area at the sink uses side lighting with moderate color temperature and high color rendering to reduce facial shadows and enhance the user experience; the overall ambient lighting remains soft to avoid glare or dimness.

5. IoT Management Platform: Data-Driven Efficient Operations and Maintenance
Devices such as people counters, soap/tissue level monitors, and ammonia sensors are deployed to collect real-time usage data. For example, ammonia sensors can monitor odor concentration and automatically trigger the exhaust system; people counters predict peak times to adjust cleaning frequencies in advance. This data is integrated and analyzed through an IoT platform, helping managers optimize resource allocation and achieve intelligent, refined operations and maintenance.
