Significant Energy Savings Realized with the Adoption of 'Kashikoku Setsuden Plus': Launch of 'Beauty Toilette' PV and EVX Series Warm-Water Bidet Toilet Seats

Panasonic Housing Solutions Co., Ltd. (President and CEO: Shoji Yamada, Headquarters: Kadoma City, Osaka Prefecture, hereinafter 'the Company') will release two instantaneous models and three storage models of the 'Beauty Toilette' warm-water bidet toilet seats on June 23, 2026, featuring further evolved proprietary power-saving functions. Product Name: Beauty Toilette PV Series / Beauty Toilette EVX Series Product Numbers (□ indicates color code): DL-PV20□ / DL-PV10□ / DL-EVX20□ / DL-EVX10□ Suggested Retail Price: Open Price (*1) / Open Price (*1) Deodorizing Function: Yes / No / Yes / No Water Heating System: Instantaneous / Storage Annual Electricity Cost (*2): Approx. 3,220 yen / Approx. 4,370 yen Annual Power Consumption (*3): 104 kWh/year (140 kWh/year) / 141 kWh/year (194 kWh/year) ■ Background In Japan, especially after the COVID-19 pandemic, heightened hygiene awareness has led to the widespread adoption of warm-water bidet toilet seats in general households, and consumer demand is primarily concentrated during the replacement cycle. Furthermore, due to the recent surge in electricity rates, consumers' energy-saving awareness is increasing, making the energy efficiency of warm-water toilet seats a crucial factor in their choices. Therefore, the Company will launch new products equipped with 'Kashikoku Setsuden Plus', which achieves significant power-saving effects by further evolving the proprietary 'Kashikoku Setsuden Smart Heated Seat' function that learns daily schedules. Moving forward, under the business slogan 'Creating "Always" in Lifestyles: "Green Housing"', the Company will continue to propose high-quality spaces that enrich daily life while remaining environmentally friendly. 1. Equipped with 'Kashikoku Setsuden Plus', which can reduce the annual electricity cost of approximately 3,220 yen by up to about 38% (*4). 2. Adopts 'Power Beat Washing' (*5), which controls the flow rates of two water streams to deliver a powerful spray. 3. Hygienic and easy-to-clean stainless steel & sanitizing (*6) cleaning nozzle. [Features Detail] 1. Equipped with 'Kashikoku Setsuden Plus', which can reduce the annual electricity cost of approximately 3,220 yen by up to about 38% (*4). The 'Kashikoku Setsuden Smart Heated Seat' learns the usage patterns of the heated seat over 24 hours a day, 7 days a week, in 1-hour increments. It compares data weekly to initiate gradual power savings, memorizing unused days and times to adjust the temperature, repeating efficient power-saving to maximize energy conservation over 5 weeks. The new products are equipped with 'Kashikoku Setsuden Plus', a further evolution of this feature. It refines the 1-hour learning increments down to 15-minute increments, demonstrating higher precision learning effects. It improves power-saving effectiveness by approximately 4% (*7) from the roughly 34% of the previous model (PSTK series), achieving a maximum power savings of about 38% (*4) compared to units without power-saving features. 2. Adopts 'Power Beat Washing' (*5), which controls the flow rates of two water streams to deliver a powerful spray. Warm-water bidet toilet seats use either an 'instantaneous' or 'storage' system for heating water. While 'instantaneous' systems generally have superior energy efficiency, their water volume is lower. Consequently, some consumers who switched from the traditionally widespread storage types to instantaneous types felt the washing strength was insufficient. To address this, the highly rated 'Power Beat Washing' from the RT series is now incorporated into the PV series. By controlling the flow rate ratio of the water streams, it automatically alternates between a narrow and thick spray, creating a cohesive, mass-like stream of water to powerfully wash the user. The washing strength is about 1.2 times that of the previous product (PSTK series), while operation noise and vibration during washing have been reduced. 3. Hygienic and easy-to-clean stainless steel & sanitizing (*6) cleaning nozzle. The nozzle, which is prone to dirt concerns, utilizes durable, stain-resistant stainless steel. Furthermore, the nozzle is automatically cleaned before and after use. Additionally, the nozzle shutter, which protects the nozzle tip from external dirt, opens and closes only during use to maintain hygiene. The nozzle shutter incorporates Ag+ antibacterial treatment (*10) to keep the area around the nozzle even cleaner. *1 This product is sold through limited channels. Some stores will sell it at the manufacturer's specified price. *2 Estimated unit price for electricity: 31 yen/kWh (tax included) [Revised July 2022]. *3 Annual power consumption calculated for a family of 4 (2 men, 2 women) [Room temperature: 5°C (Winter), 15°C (Spring/Autumn), 28°C (Summer), Water temperature: 15°C].
