Development Background: Eliminating “Near Misses” with Fans
While fans are indispensable for summer living, moments where infants or children reach for the blades or guard are common “near misses” experienced in many households. To address the simple desire for “a fan that stops immediately when it should,” this new product was developed. It is designed to offer not only coolness but also energy efficiency, quietness, and safety, all in one unit.
Features
1. “Touch Stop Function”: Automatically Stops the Moment It’s Touched
The product’s most significant feature is the “Touch Stop function” with its “two types of Anshin Touch.” The first Anshin Touch is a temporary stop function. If a hand touches the guard during operation, the fan immediately stops to prevent danger. It then automatically resumes operation after approximately 5 seconds, ensuring safety without sacrificing convenience. The second Anshin Touch is a complete stop function. If the guard is touched continuously for 10 seconds, the power turns off. This addresses situations where a child might hold onto the guard without letting go. When a complete stop occurs, operation needs to be restarted by pressing the “On/Off” button, allowing users to confirm safety before resuming use.

2. “DC Motor Adoption”: Comfortable Wind with Energy Saving and Quietness
This product utilizes a DC motor, with a power consumption of only 21W (50/60Hz common). When used for 8 hours a day for one month (30 days) at maximum power consumption, the estimated electricity bill is approximately 155 yen (calculated at an average electricity rate of 31 yen/kWh). This makes it an economical choice for households looking to reduce daily electricity costs, especially when used in conjunction with air conditioning.
Furthermore, the DC motor’s quiet design ensures that operating noise is barely noticeable during sleep, making it safe for use in nurseries and children’s bedrooms.
3. “7-Blade × Rhythm Wind”: Delivers Soft, Natural Breeze
The fan features 7 blades. Compared to common 5-blade fans, the wind cutting noise per blade is dispersed, resulting in a quiet, soft, and expansive airflow that gently envelops the room.
It also includes a rhythm wind mode, which delivers a natural, fluctuating breeze with varying strengths. This simulated natural wind in the room reduces strain on the body, allowing users to enjoy the comfort of a gentle breeze under the shade of trees.

4. “6-Level Airflow × Diverse Timers”: Fine-tuned Control for Your Lifestyle
The airflow can be adjusted in 6 levels, from gentle breeze to strong wind, allowing selection based on the day’s temperature and activity. Timer functions include a 6-hour on-timer and a 6-hour off-timer. Using these during sleep can alleviate excessive cold at night or discomfort upon waking. Additionally, an 8-hour automatic off-timer prevents wasteful power consumption due to forgetting to turn it off.
5. Design: Two Colors to Blend into Your Interior
The beige model (model: YT-DS3431HFR(C)) offers a warm color that blends seamlessly with natural, wood-themed interiors and bright living spaces. The blue-gray model (model: YT-DS3431HFR(AH)) is a sophisticated nuanced color that complements modern interior designs. Despite featuring a touch sensor, the color guard maintains its aesthetic appeal. The blades, remote control, and remote control holder are all color-matched to the main unit, making it an ideal choice for those who prefer a clean, uncluttered look or a cohesive color scheme.
