With the introduction of the first patented dishwasher, much has changed. Modern technologies combined with the experience of world leaders led to the emergence of different types and types of dishwashers. Now the buyer has to choose between one, the other and the third models, so as not to make a mistake and buy a machine that will fully meet his needs. All questions about the differences, pros and cons of each type of PMM will be considered in the review.

Features and differences of different types of dishwashers
Several decades ago, it was not difficult to answer the question about what types of dishwashers there were, because the choice was modest. And today, with the development of engineering and technical thought against the backdrop of worldwide progress, cars are being manufactured in various forms and forms, which has caused a complex gradation.
We will describe the simplest classification, which includes all types of modern PMM. This hierarchy is presented in detail on the diagram:
All dishwashers are divided into two main varieties: domestic and industrial.
Industrial machines in turn are divided into:
- Frontal. Their design is similar to household appliances - in front there is a loading hatch, and inside - dish baskets. The control panel also resembles a household. The difference is one: as an assembly, reliability and duration of work. All front industrial dishwashers are made of high quality metal (external and internal parts). Also, such models wash large batches of dishes and serve several times longer than "domestic helpers."
- Dishwashers of dome type. Original industrial options without a door. The container with dishes is covered with a washing tank, which resembles a dome - hence the name. To this technique, additional sectors are often added: a sink and a table for sorting dirty dishes and appliances.
- Tunnel type - the most cumbersome and powerful "giants" of the dishwasher industry. They are suitable for canteens and other large catering establishments. They are often called "conveyor belts because they remind exactly this useful invention. The conveyor moves dirty dishes, getting into the tank for washing, where it already comes out perfectly clean.
Important! Tunnel dishwashers require a large area - at least 18 square meters.
Today, many firms in Russia and abroad produce similar equipment for industry and business. The cost of this technique is high, in a domestic environment, such machines will be of no use.
Household dishwashers, which are usually faced by the consumer, are divided into the following classes:
- small (or compact).
Full-size technology has its name due to external parameters. Usually the dimensions are as follows: height - 82-87 cm, width - 60 cm, depth - 55-60 cm. Such a machine can wash 10-17 sets of dishes at a time, so these are the most capacious and productive options. There are models that are partially or fully integrated into the kitchen set, as well as stand-alone structures.
Among the full-size cars can also be foundcombined. They are combined with other household appliances - hob, gas stove, oven. This is a relative novelty in the market, so the price is high for the average user, from this and the demand for combined options is modest.
Narrow dishwashers from the previous distinguishes the width, which ranges from 4 to 49 cm. By type of installation, the division is exactly the same. Suitable for a kitchen with a limited space and a ready-made kitchen.
Small or compact models coming in sale in recent years can also vary in type of installation. Uniform standards are not available in sizes, dimensions can vary: 50-69 cm in width, 50-55 cm in depth, 44-60 cm in height. An excellent option for a small kitchen.
Which PMMs are more reliable, more economical, more productive
To determine the reliability of the dishwasher, it is worthwhile to focus on several features:
- What is made of a bunker, rocker arms and container containers. The less plastic and more metal, the better. To save in compact and narrow models, plastic parts are often found, so the conclusion is obvious.
- Electronics - the more difficult, the more vulnerable. Constructive complexity of PMM is convenient, but unreliable. If the electronics breaks down, the repair "will fly into a penny sometimes up to half the cost of the unit.
- Manufacturer country. It is generally accepted that the most reliable technology in the world is German (such brands as Miele, Bosch, Siemens, AEG). Good indicators of trust and service life of Italian technology. Unfortunately, cheap Chinese machines of trust still do not deserve, in view of their frequent breakdowns, although there are also quite worthy brands - how lucky.
How to save money
The economy is even more difficult to estimate - here you need to take into account the characteristics of a particular model. In general, full-size PMMs consume 11-12 liters of water per wash cycle.
Important! Among full-size cars there are models of a premium class, which spend no more than 10 liters per wash. So, Neff 51M65X4 requires only a liter of water. But the cost of such a model is not affordable for everyone.
Compact machines consume 5-6 liters, which is the most ideal indicator for fans of savings.
Important! The economy of a small model is calculated based on the frequency of launches per day. If you use the technique three times a day, with a consumption of 6 liters, a small model will consume 18 liters of water, which is almost twice as much as a full-size PMM.
Exactly the same logic in terms of electricity consumption. Conventional machines consume about, 3 9 kW / h, small - 1 kW / h. With the double launch of a compact economy-class model, the energy consumption will be greater than that of a machine with full dimensions.
The quality of washing in modern machines is quite high, regardless of the design. So, a machine with a preliminary wash or "Soaking" has more chances to wash off old pollution. Even better results for those models in which the use of capsules and tablets "3 in 1" is permissible, and also with a wide variety of temperature regimes.
Important! In order to anticipate the quality of washing in advance, pay attention to the washing class. It must be at least A.
The cost of dishwashers of different types
The final price of a dishwasher is not that it depends on the type of construction. Often the cost rests on the brand and the country of origin. For the European, and in particular the German, assembly will have to overpay by at least a quarter. The price is also affected by the cost of an individual company's advertising campaign - the more funds are spent on promotion, the brighter it is reflected in the cost of technology, although in this issue, some firms have chosen a different policy.
So, Bosch has focused on budgetary equipment, so even the cost of advertising and maintaining the status of a world leader does not leave a mark on the cost.
According to the rules of marketing and economy, the final cost of the product is influenced by such factors:
- Country of origin, brand;
- country of assembly;
- the degree of novelty, the number of "chips" and improvements;
- technical complexity of the structure.
The high price for combined equipment is due to the availability of a gas stove or oven in the complex, but also the combined models are not the most expensive - they can be purchased at a price of 100 000-120 000 rubles, whereas the usual PMM from the German company De Dietrich costs all 200 000 rubles.
Important! Also the cost can depend on the type of control, class of washing, drying or power consumption. Carefully read the information sticker when buying. If before the class of electricity consumption was not higher than A, then today one can meet A +, A ++ and even A +++.
How the first PMM appeared
The world's first dishwasher was created by a resident of the United States. Her "ancestor" - Joel Goughton. It would be fair to call him just an author of the idea, because he failed to translate his work into reality. The first machine was difficult to use, it required physical efforts, and the quality of washing left much to be desired. Later, Goughton decided to automate the process, but it remained on paper and did not find any mapping in real developments.
The invention of Josephine Cochrane is more like what we are accustomed to calling a dishwasher. In its technical novelty, the basis of the design was piston pumps operating on a manual drive. Also in the typewriter was a heater that heated the water, and a basket into which the dishes were stacked.
It is interesting! Development Cochrane turned the idea of washing dishes, but found no recognition because of the high cost and still poor quality of washing.
The history of the MMP has continued in Europe. The first automatic dishwasher was created in 1929 by the engineers of the German company Miele. The device did not require user input, and hot water was sent to the hopper by an electric pump. In 30 years, the same company produced the first dishwasher in the design known to our contemporaries, which worked in automatic mode. 1960 can be safely called the year of the invention of modern PMM.

Summarize. Despite the fact that the choice of types PMM is huge, you can always easily choose the right option for home or business. The main thing is to determine the criteria that the machine should answer, and immediately indicate the budget for the planned purchase.
