Application of thick film heating technology in sink dishwasher

- Jul 11, 2020-

At present, a variety of small dishwasher has been on the market, is gradually entering the ordinary family. In the field of heating, the traditional electric heating wire is eliminated and the thick film heating technology is adopted instead. The thick film heating plate or tubular thick film heater is installed at the bottom of the sink of the dishwasher. In this way, not only the installation space of dishwasher is saved, but also the assembly of other components is more convenient, and the cleaning of heating components in the process of use is more convenient, which brings better user experience.

The water temperature of the general household dishwasher is about 50 ℃ - 70 ℃, and the specification can be determined according to the number of the respective family population. If the family of about 3-5 people, the dishwasher with the specification of 700w-900w can meet the daily use. Dishwasher uses advanced technology and mature thick film heating technology, which makes heating and constant temperature more rapid and convenient.


Traditional dishwasher can only meet a single dishwasher requirements. The sink dishwasher can not only wash dishes, dry, sterilize, but also remove the residues on the surface of fruits and vegetables, with more functions! Sink dishwasher is entering thousands of households, with several advantages in the field of cleaning unique. The advantages of sink dishwasher are small size, do not need to occupy too much kitchen space, easy installation; full function, not only dishwasher, but also sink, can also be used as fruit and vegetable purifier, one machine is multi-purpose.

The dishwasher washes the tableware surface with 360 ° mechanical washing by high temperature and high pressure water flow, and the oil and residue on the tableware surface are decomposed by detergent, and the food residue is soaked in hot water, which makes the oil and residue decompose and fall off quickly, and achieves the dual effect of cleaning and sterilization. The working method of dishwasher is based on the combination of mechanical action and chemical action. The washing mechanism is as follows: mechanical action, the washing liquid is in spray state, and the washing liquid washes the tableware surface indirectly. The washing liquid rebounds after spraying to the tableware and the tank, and the washing effect of the returned washing liquid on the tableware surface after spraying; the chemical action, the detergent added in the washing process has a good alkaline saponification reaction with the grease in the tableware.

This kind of sink dishwasher with thick film heating technology has a heat efficiency utilization rate of 98%. On the one hand, it can reduce heating time and energy consumption. In the process of use, the water flow is heated by water pump, and the water temperature is more stable. High temperature and high pressure spray is used to decontaminate and fully disinfect the dishwasher. Experiments show that the dishwasher uses 20% less than hand washing Water.

The dishwasher uses stainless steel thick film heating tube. The power density of the thick film heating element can reach 60-200W / cm? 2, which can improve the heating efficiency and reduce the energy consumption;

At the same time, the thick film heating element is made of food grade stainless steel, which is safe and reliable in hygiene. The thick film heating element adopts SUS444 or SUS430 stainless steel base pipe, which has high corrosion resistance and long service life;
