Application of dual power thick film heater in intelligent water purifier

- Jul 11, 2020-

According to the analysis data, the next 10 years will be the golden decade for China's consumption upgrading. The rapidly rising middle class will provide demographic dividend for the middle and high-end water purifier market. At the same time, it will also be a decade for enterprises to join hands in product segmentation. The middle class has higher requirements for the design taste, function and quality of water purifier. Under this background, many enterprises are competing to launch intelligent, multi-functional, instant intelligent water purifier. Next, it introduces the application of dual power thick film heater in the field of high-end intelligent water purifier.

The intelligent water purifier adopts a new generation of stainless steel rare earth thick film heating technology, the heating efficiency is as high as 98%, the thermal response speed is as fast as 80 ℃ / s, there is no power attenuation, and the service life is as long as 10000 hours. The water and electricity separation structure is adopted, which is safe and durable. Due to the use of dual power thick film heating elements, combined with flow control, it can realize 7-gear temperature change while ensuring instant heat. It can be used for making milk powder at 45 ℃, honey water at 55 ℃, coffee at 65 ℃, scented tea at 75 ℃, green tea at 85 ℃ and black tea at 95 ℃. It can meet the different uses of Baoma, fashionable white-collar workers and middle-aged and elderly people in the middle class.


What are the advantages of dual power thick film heater?

The above figure shows a conventional single power stainless steel rare earth thick film heating tube. The whole heating tube has only one rated power. Taking the product of 220 V / 2200W as an example, when the single power heating pipe is used on the drinking water machine, without the intervention of PWM power regulation module or silicon controlled rectifier, the output power can only be constant at 2200W, which can meet the requirements of water temperature from 65 ℃ to 100 ℃. However, according to the law of conservation of energy, the high power of 2200W can not meet the demand of low-temperature water in the case of small flow of water, such as water at 45 ℃ and 55 ℃, so the function of the water dispenser is not perfect.

Using dual power thick film heater, taking the rated power of 220 V / 2050w as an example, the power is divided into 685w, 1365w and 2050w. Drinking water dispenser can use 685w heating power alone, 1365w heating power alone, or 2050w total power. The whole water purifier does not need to be equipped with power regulation module, only need to write a reasonable electric control program, and add two relays, the outlet water temperature of 45 ℃ ~ 100 ℃ can be realized, taking into account the cost and performance, and the stability of the whole machine is guaranteed.
