Renewal Highlights
1. Increased Capacity to 40 Place Settings with Maintained Washing Power
The storage capacity has been expanded from 36 to 40 place settings, making it possible to wash dishes for a family of four plus cooking utensils in a single cycle. This contributes to reducing household chores and saving on water and electricity costs. The spacious interior accommodates large plates up to 27cm in diameter and frying pans up to 27cm. A rotating nozzle has been added to the bottom of the upper basket, ensuring that water flow reaches all parts of the interior effectively, thereby maintaining washing performance despite the increased capacity.
2. 20% Reduction in Installation Space with “Top Exhaust”
One common concern when considering a dishwasher purchase is the required installation space. To address this, the exhaust vent has been moved from the rear to the top of the unit. Previously, 15cm of clearance was needed behind the unit, but with the new design, only 5cm is required, resulting in a 20% reduction in the total installation area. The minimum required installation space is now approximately 60 cm (width) x 40 cm (depth) x 70 cm (height).
3. “Auto-Open Function” on Both Models for Gentle and Eco-Friendly Drying
Both models now feature the Auto-Open function, which automatically opens the door after washing. This allows steam to escape, reducing condensation and promoting natural drying of both dishes and the interior. This natural drying method is gentle on dishes and environmentally friendly.
4. 40% Reduction in Residual Water Droplets with Enhanced Hot Air Drying (SS-LH451 only)
For the SS-LH451 model, the hot air drying performance has been further improved. Optimization of the rotating nozzle shape and the relocation of the exhaust vent to the top have led to a 40% reduction in residual water droplets, resulting in drier dishes and interior.
Product Features
1. “Automatic Water Supply System” for Immediate Use Without Plumbing, Also Usable as 2-Way Type
These dishwashers utilize an “automatic water supply system” without an internal tank. They conveniently draw water automatically from an included bucket, eliminating the hassle of manually filling the unit. As a 2-way type, they can also be connected to a water faucet, offering flexibility for various kitchen layouts or when moving homes.
2. “Uzu Max Wash” with for 99.9% Sterilization
siroca’s unique “Uzu Max Wash” cleaning technology uses high-temperature water (up to approximately 75°C) and high-pressure water jets (reaching approximately 2m) to wash dishes from all 360 degrees. This effectively cleans stubborn oil and viscous stains that are difficult to remove by hand, such as those from curry pots or bowls used for kneading meat. Additionally, the “Omakase Sensor” detects the level of dirt on dishes and automatically adjusts the washing cycle, contributing to energy savings.
