Improve Overall System Performance of The Dishwasher

Abstract: The spray wash followed a mature technology, while addressing a dishwasher you want a few technical issues of mutual restraint is almost impossible. But if we break free from the original technical ideas out to get a new technical solution, thus improving overall system performance of the dishwasher. Rotating flushing washing technology has provided us with a new idea, you can easily and thoroughly spray washing technology to solve the chronic left, quick wash, low efficiency, power saving water, no detergent, and other Kinds of technical goals. First, spray washing technique, and the plight of the status of Washing dishes by mechanical means patent first appeared in 1865, but the real family is in the last century into the 50's, now as an important member of the modern kitchen appliances, dishwashers have a very high penetration rate in foreign countries, the United States and major Western European countries penetration rate has reached 60% to 70%. Work is dishwasher detergent dissolved in water, heat and pressure, rushed to be cleaning utensils, washing water, then rinse with water exchange, so washing dishes a few times, to complete a wash. Wash or use their own heating elements heat the dishes dry heated air, so some countries, also known as the dishes of their dryer. After 100 years of development, dishwasher has reached a considerable improvement in the technical level, this is the so-called spray-type dishwashers. Suitable for this type of dishwasher cutlery tray as Westerners use forks. At present, domestic and foreign manufacturers producing dishwashers sold almost all belong to this spray dishwasher. Compared with traditional manual dishwasher, dishwasher does have many advantages: Because wipe eliminating manual steps such as washing dishes, and added to the sterilization, drying and other sectors, reducing the chance of virus infection; the use of Water rinse cycle, and some stratified wash, so have some water effects; there are some models the function of softening water can reduce the formation of scale inside; some three-dimensional jet flow with the aim of The deep corners of the bowl can be cleaned. The dishwasher has a defect it is difficult to accept. The first is washing a long time. Since the whole setup process is a process, even if only a few pieces of tableware, but also to go completely process. Common dishes are usually stains less time-consuming more than 10 minutes. With drying and disinfection process, will have more than one hour. Second, many dishes wash clean. Dishwasher final analysis, the introduction of "variety", after the transformation still does not meet the conditions. Complete sets of utensils are generally foreign, and specifications, shape are fixed, mostly dishes, special dishes less. Therefore dishwasher "deal" they are also well placed to exploit, wash very place. We mostly used the table for bowls, and dishes are not complete sets of specifications and shapes. Dishwasher rack put bowl design is not suitable for the requirements, making it difficult to spray water rinse greasy deep bowl. Third, from the perspective of saving water and energy test, dishwasher through "a clear second wash " procedure charges than the hand wash water heater and dishwasher in the 900W-2300W power range, dishwasher, 80% of the power consumption Heated in water, using high power washing means 1 degree above normal. Fourth, the dishwasher needs special detergent, which not only give consumers a certain amount of inconvenience, and gave the addition of new water pollution, are products of environmental pollution. In addition, the structural design, materials, use of certain defects, dishwasher cleaning tank attached to the greasy hard, every day, often using the dishwasher to "machine wash the dishes, the washing machine"embarrassing phenomenon. At the same time dishwasher also has a high price, together with electricity, water and special detergent costs of such investment indefinitely, so that working-class consumers to stay away. With so many performance deficiencies exist, spray-type dishwasher has not been able to enter the family of ordinary people. Although there are Haier, Midea, Little Swan, Ao Kema dishwashers and other appliances production, but has not been able to form a market size, did not breed like color TV, refrigerator, washing machine influential new industries.Second, the technology constraints of the relationship between a number of technical difficulties Dishwasher technology development should be to solve the following problems: 1.Wash faster, especially for restaurant restaurant, due to large dishes, saving time appear to be more urgent.2.Effective wash bowl tableware, China and many Asian countries are based mainly tableware bowl.3.Energy and water, China is a serious shortage of energy and water areas, both energy and water conservation are important to society or individuals.4.Without detergent, this will not only reduce the use of the trouble and expense, while reducing water pollution.5.Capacity in the dishwasher, the dishes less less water, and time should be reduced.6.Operation is simple to use, cost price is low, household consumer goods affordable favorite.7.To clean the dishwasher itself, no smell, so as to facilitate health dishwasher bowl cabinets. For spray washing technique, dishwasher through the motor-driven pumps, so that wash water under pressure from the spray arm spray, spray water from the mechanical impact on the role of the surface of dishes, dishwasher, washing soap on the dishesthe role of surface oil from a chemical decontamination, together with hot water from soaking to soften the role of physical and chemical effects of three dishes together to make the surface oil and residue decomposition and the stains off, so as to achieve the purpose of cleaning utensils.It can be seen, wash ability and washing time, hot water, detergent directly related to the amount of three parameters, if the latter three in one or several technical parameters decreases, then the cleaning efficiency is bound to worsen.So wash wash ability and speed, energy water, special detergents formed between the four constraint relations, the 4 can not be completed at the same time enhance the technical performance. In the spray washing technique, the first four have been impossible to simultaneously address the technical difficulties, not to technical difficulties will be above 7 to get rid of.Dishwasher energy consumption due mainly concentrated in the heating water, the United States dishwasher manufacturers in order to design energy-efficient dishwasher, turning to target the reduction of water, the water or energy; Korea equipped with Magic-type dishwasherA new structure of the double-pass valve, the valve's ultimate goal is to use cold water to reduce water and energy consumption.These technical efforts, you can reduce the amount of energy consumption of dishwashers, but to improve the cleaning speed to remove detergent, reducing the cost price without any effect. Third, multiple solutions to problems The technical issues for further analysis: the ability to ensure the clean case, if the wash time is shorter, less power consumption of water, so wash rate is conducive to improving energy and water saving dishwasher. We know that: If we do not have detergent to save the washing process of the role of chemical energy; the same time we do not heat water, eliminating the need for washing process is the role of heat; this time the only thing left is to use Mechanical energy to wash dishes. Dishwasher with spray, water, the impact is not strong, relying on a single machine can not wash dishes. However, if the plate in motion, then rinse in cold water, the availability of sufficient mechanical force to achieve the purpose of cleaning utensils, which acquired a new technology program - rotating flushing washing technology. Flushing Rotary washing technology principle is: the use of cutlery utensils rotation and the impact of two physical processes water, by water at high speed rotation of the dishes have a strong impact on the surface produces centrifugal wash utensils and fixtures. The structure of the dishwasher through the folder to a bowl in the dishwasher cutlery rack clamp, drag from the motor with rotary washing utensils and water pipes driven move, followed by a continuous rotation of the dishes to flush.
