"Black whirlwind" spiral heater
The "Black Cyclone" spiral heater is the fifth generation "HES" (thermal switch) new heater independently developed by piano, which has the following characteristics:
No water leakage: the inner wall of the heating tube and the nickel-chromium heater are filled with insulating and heat-conducting magnesium oxide, and the heating tube is completely isolated from the waterway, which abandons the traditional mode of heating the heating tube directly in water with a cup heater, truly realizes the design of "separation of water and electricity" and fundamentally eliminates the possibility of water leakage.
No water leakage: totally enclosed design is adopted, and the whole heating element is formed at one time, without any seams and solder joints, completely eliminating the possibility of water leakage.
No scaling: When the "black cyclone" heater works, the heat energy generated by the nickel-chromium heating element is transmitted to the water guide pipe wound on the heating pipe, and the water flows spirally in the water guide pipe to heat evenly, thus completely abandoning the traditional heating mode that the cup-shaped heater suddenly heats at high temperature and uses boiled water to exchange cold water to reach the bathing temperature. The unique "black whirlwind" heating mode is uniform, large in area, low in temperature and flowing, effectively avoiding the generation of scale.
Fast, efficient and long life: faster heating speed, real hot water in 3 seconds; The heat efficiency is higher, the heat conversion rate is above 99.5%, the service life is longer, which is more than twice that of the traditional cup heater, and the effective service life is more than 10 year.
"IFS" infrared flow switch.
On the premise of ensuring the constant temperature of the water heater, water flow switch is the key component to detect the inlet water temperature and inlet water flow. The "floating magnet" switch is widely used by other quick-heating electric water heater manufacturers. Because there are impurities in the water flow, its magnetism will be weakened or even blocked for a long time, which will lead to dry burning of the heating element or start heating as usual under the condition of lower than the allowable water pressure, which will eventually cause burns and scalds to the user. Piano adopts the patented "IFS" infrared water flow switch, which completely abandons the above defects. Through the infrared receiver, the water flow is accurately measured and the data is transmitted to the microcomputer (CPU) for processing. Only when the water flow reaches the minimum preset value can the heater be reversely commanded to heat, effectively preventing the heater from scalding the user caused by dry burning or low water pressure start-up. "IFS" also transmits the data of water inlet temperature to the microcomputer, which comprehensively analyzes the water flow, water inlet temperature and user preset temperature, accurately calculates the required heating power, and instructs the SCR device imported from Germany to automatically control the power output, thus truly achieving the purpose of constant temperature shower. In addition, infrared ray has antibacterial and bactericidal functions, which can effectively purify water quality, avoid bacterial invasion and benefit skin health.
