This is the 147th article by YEATION, a home furnishing teacher.

Andy found that in recent years, people have paid more attention to the dishwasher. Many friends will struggle whether to install one, and netizens have different opinions. @ Arrow:

A family of three, a wok, an electric cooker liner, two plates and three. I really think it's easier than putting it in the dishwasher and then taking it out ...

@ meow:

Basically, only men who don't wash dishes and the older generation are opposed to buying dishwashers, and most women and men who wash dishes want to buy dishwashers ...

The reason why the popularity of dishwashers is not so high is that people don't know much about this new thing, especially the older generation. Today, Andy will show you about the dishwasher.

Two big doubts about the dishwasher

Is it clean?

Andy first talks about the general working principle of the dishwasher:

1. Clean the dishes with cold water through the spray system;

2. Use hot water mixed with detergent (about 71℃) to wash tableware forcefully from multiple angles;

3. The circulating water is rinsed repeatedly, so that the oil stains can be quickly decomposed and shed;

4. spray at high temperature and finally dry.

▲ before cleaning vs after cleaning

Compared with hand washing, the process of high-pressure water column washing+high-temperature washing+drying actually has more advantages in washing dishes, at least hand washing is impossible to stay in high temperature for a long time.

do you feel that you are wasting water and electricity?

It is generally believed that washing the dishwasher for such a long time is really a waste of water and electricity. But in fact, this is not the case.

hand washing uses direct current water, and the water discharge of the faucet is random, so it is actually more "arbitrary" to clean, and it takes about 1.5 ~ 31l of water to clean once.

The dishwasher uses circulating water. When it works, it will feed a certain amount of water according to the selected mode, and then start circulating cleaning, instead of continuously feeding water. The water consumption is about 5~13L each time. (This is related to the model, volume and washing mode, as well as the power consumption)

So on the whole, the dishwasher actually saves more water.

As for the power consumption, you don't need electricity for hand washing at ordinary times, but in the chilly weather in winter, you really don't have the courage to put your hands in the water without boiling hot water, and boiling hot water also consumes electricity.

As for the dishwasher, Andy went online to read the relevant product information. The power consumption of the dishwasher is about 1.5~1.3 degrees, which is not as power-consuming as many people think.

Is it really that good?

As the saying goes, "Everything has two sides." Just because you bought a dishwasher doesn't mean you really don't have to worry about anything.

pretreatment

pretreatment is very important in the use of dishwashers: first, clean up the food residue on the surface of tableware (no need to wash it by yourself), and second, put the tableware in the dishwasher according to its classification.

Each dishwasher will have a corresponding instruction manual, which indicates what type of tableware to put in different areas.

There should be a gap between the tableware, not next to each other. Pay attention to check whether the washing arm is blocked by chopsticks, spoons and other long tableware, otherwise the operation of the dishwasher will be affected.

If there are few dishes to be washed, you can put them at intervals.

It can't replace the disinfection cabinet

The working temperature of the disinfection cabinet can reach 1.21℃, which can ensure the complete evaporation of water on the surface of tableware and achieve the effect of sterilization and disinfection, which the dishwasher can't do.

So after the washing procedure of the dishwasher is completed, we need to take out the tableware in time or turn on the ventilation.

Not all tableware can be washed

Just as not everything in the microwave oven can be put into it to be heated, not all tableware can be washed in the dishwasher, such as disposable plastic products, glued tableware and silver-copper-aluminum coated products.

it's best not to put wooden tableware and kitchen utensils in it. Unless there is a sign that they can be put in the dishwasher, they will be easily deformed or moldy.

How to choose a suitable dishwasher

Types of dishwashers

There are three types of dishwashers in the market: independent, embedded and sink (according to installation methods). If you want a dishwasher before renovation, you can choose embedded and sink type. If you want it after renovation, you can choose independent type.

independent

independent dishwashers can be divided into bench-type and floor-type according to their capacity, which is relatively flexible in placement and use, and there is no reserved position in the cabinet.

The table type is relatively small, and even a pot can't be put down. The advantage is that it only occupies a small part of the cabinet countertop, which is suitable for families with little kitchen space; The floor-standing type is more suitable for families with many people.

At present, some independent dishwashers have a 1/2 small amount of tableware program, so that when there are few tableware, the water and electricity used will not be the same as when there are many tableware. Speaking of price, independent ones will be relatively cheaper.

Embedded

is a dishwasher that can be embedded in the cupboard, ensuring the spacious and clean kitchen. After determining the specific products, remember to send the relevant dimensions to the decoration company, and reserve the corresponding water supply and drainage pipeline positions.

The sink type

The sink type is a dishwasher installed in the kitchen sink, which does not occupy other positions and has the function of cleaning fruits and vegetables. It is simple and convenient to use, but the price is not cheap and the capacity is not large, so it is a bit difficult to wash the pot.

About drying technology

There are three main drying technologies for dishwashers in the market: waste heat drying, fan drying and heat exchange drying (which will be more expensive). After reading the table made by Andy below, you can know more intuitively how to choose the volume.

When choosing a dishwasher in a shopping mall, besides asking about the brand, the number of sets is the most frequently asked by the salesperson. The number of sets is the volume. Dishwashers on the market range from 4 sets to 13 sets.

(Image from the Internet)

Generally speaking, 4-6 sets are selected for a family of two, 8 sets for three or four people, and 13 sets for more than five or six people will be more suitable, which should be considered from the aspects of the number of family members, cleaning frequency, kitchen area and budget. Of course, if conditions permit, the bigger you buy, the better. It is more convenient to put the pot in and wash it.

if it's for the elderly, Andy suggests choosing a sink or a desktop, so that the elderly can use it standing without bending over often.

There are also some points to pay attention to

1. It is best to buy a dishwasher with a new spray arm

Compared with the old single nozzle, the outlet of the new spray arm has a large enough coverage and greater cleaning power. However, it should be noted that the higher the water pressure, the better. If you are not careful, you will wash the dishes.

2, it is better to have a built-in water softener

Friends in the north suggest choosing a dishwasher with a built-in water softener, because tap water contains more hard calcium and magnesium ions, and it is easy to scale when it is directly used to wash dishes.

3, to see the design of the bowl and basket

Dishwashers are, after all, invented by foreigners. Some foreign brands of dishwashers have relatively small intervals between the steel wires of the bowl and basket, so it is ok to put dishes, but it is difficult to put bowls. It is better to choose one suitable for Chinese families.
