As life shows, you can equip the kitchen eitheras a "production", utility room, or as a territory for enjoyment. The utilitarian approach has remained in the past. The kitchen space is becoming actual, combining ergonomics, aesthetics, design and comfort. With the help of household appliances, you can conceptually modify the interior of the kitchen. After all, it includes a large number of different in size and purpose modules - electric and gas surfaces, grills, hoods, etc., which can be combined with each other in style in any combination. But the center of all this technological splendor still remains the stove - the modern version of the home, which has been the subject of special attention since ancient times. Fire from time immemorial served people. Preparing food without it is completely impossible. Since then, the hearth has undergone many changes over the centuries, but little has changed in the first principle: fire still serves to prepare food. Today we will talk about which gas cooker is better to buy. What are they, modern hearths? What metamorphoses have they undergone in recent times? Note that we will not talk here about cooking surfaces and ovens, namely gas stoves. Therefore, to begin with, it is worth investigating what a stove is. This definition is often applied to both a separate hob and a design in which an oven is built under the panel. But the stove is an oven and a hob combined together in a single casing.
In accordance with modern norms, the gas pipelinecan only be brought to those apartment buildings, whose height is not more than eleven floors. In private country houses, there are no such problems. Here you can both bring gas to the house from the central gas pipeline, and buy gas cylinders in addition to the stove. But then you need to take into account other norms that apply to apartments in urban high-rise buildings. Gas equipment according to the current regulations can not be installed in rooms where the ceiling height does not exceed 2.2 m. In addition, in this room must necessarily be an exhaust ventilation duct and natural light, and the window must be with a window. Moreover, it turns out that the internal volume of the kitchen plays a role. For a plate with two burners, it must be at least 8 m³, and for a four-burner plate - 15 m³. But if your home meets all of the above requirements, you will be available all the benefits of using a gas stove. And the main advantage of gas is its cheapness compared to electricity. After all, according to statistics, users of gas stoves spend for their use an average of ten times less money than the owners of electrical. It should be noted at once that the gas stoves do not differ much in size from each other. Their dimensions are standard and correspond to the dimensions of the kitchen furniture. Their height is usually 85 cm, depth - 50 or 60 cm, and width - from 50 to 90 cm.
Pros and cons of using gas stoves
We have already discussed one virtue. This is the cheapness of energy resources. Another advantage of gas cookers in comparison with electric cookers is that there are no special requirements for dishes that can be used for cooking. For example, it is better to use dishes with a flat bottom on electric cookers in order to maximize the use of heating. On the gas stove you can cook in the cauldron, which is very convenient for preparing many delicious dishes. An important advantage is that it is possible to regulate the degree of heating in its own discretion. Well, among other things, food cooked on an open fire seems much tastier. But there are certain drawbacks, which, however, do not outweigh their merits. First, we must follow when using the gas stove for clean air in the kitchen and for safety. Secondly, we must monitor the plastic parts of the dishes - so that they do not directly appear over an open fire. Well, in operation they are a bit more complicated - they are harder to clean than electric ones.
Burners are the very essence of a gas stove. Their quantity and power will depend on the performance of your cooking. The burner can be from two to six, and in almost all the plates they vary in power. The smallest - 1 kW, the average - 1.75-2.0 kW and the powerful - 2.7-2.9 kW. Practically in all plates two burners of medium power, one - small and one - high. Burners transmit the cookware to 58% of the heat produced by it, and the rest is actually for heating the room. The principle of the gas burner is that it mixes in a certain proportion of combustible gas and air. The gas will burn if its ratio in the mixture is from 5.3 to 14.2%. In the case of the lower boundary, the mixture is called "poor", and in the upper limits - "rich". To ignite the gas, of course, you need a spark. The design of the gas burner is such that at low emissions of toxic substances it provides a high efficiency of gas combustion. According to the norms in combustion products there should be no more than 125 mg / m³ of carbon monoxide and more than 200 mg / m³ of nitrogen oxides. It's no secret that we constantly have gas pressure drops in gas networks. Gas plates are designed to take into account these differences: they should work stably under changes in gas pressure within 650-1800 Pa from the nominal at 1300 Pa.
The principle of operation of modern gas cookers does notdiffers from their predecessors. But, nevertheless, they can not be compared, because gas stoves have changed beyond recognition for the last twenty years. Since in their operation the main problem is security, then with the modernization of this technology, it has been given the main attention. As a result, today's plates are equipped with a more advanced gas leakage protection system. This is the so-called "gas control", which provides for an automatic gas shut-off mechanism, if, for example, the flames blow out of the wind or flood the runaway product. We will not consider the operating principle of the system. It is important that it reliably protects you from gas leaks, protecting your health and life. But not all such innovations were to their liking. The fact is that when igniting the gas you need to hold down the power switch for a few seconds, which is not very convenient. The gas control system requires that the burner is heated to a certain temperature so that it turns off. Therefore, some people, not knowing that this is how the security system works from gas leaks, prefer to buy plates without gas control, stating that they do not need it. But those who are serious about the issue of their own safety, choosing which gas stove to buy, we advise you to take one that is equipped with a security system. Moreover, gas control is also incomplete. For example, only burners can be controlled by it, and the oven does not. That is, when buying it is necessary to specify which exactly is the gas control system and what is subject to it. Another novelty was the mechanism of electric ignition, which you will not be surprised by today. Electric ignition is normal and automatic. On gas stoves with a conventional electric ignition, when turning the throttle trigger, press the ignition button so that a spark appears. Burners with automatic electric ignition are ignited automatically when the handle is turned. Very handy when cooking a timer. Gas stoves with a simple timer simply warn you with a signal that the cooking time has come. The advanced timer itself will switch on the given time plate and turn it off. It is very convenient. For example, with the help of a timer, breakfast will always be ready for your awakening. True, there is a small nuance. The timers are tuned to the frequency of the current in the 50 Hz network. Our networks do not provide such a frequency, so the timer is usually either in a hurry or late. Then the plate is turned on not at the time that you put on the program. Moreover, the error can go up to five minutes.
The surface of gas stoves can be coveredenamel or made of stainless polished steel. Enamel is famous for its wear resistance, it is not afraid of organic compounds, including acids. But it may be chipped during use. Coatings of stainless polished steel, though more expensive, but look more impressive. In addition, steel is almost not scratched and looks like a new one for a long time. But it is very visible traces of fingers. A glass ceramic surface is very convenient. It's easy to clean. But for her, the sweet liquid is devastating. Not so long ago, the gas under the glass was very heavily advertised. Now there are no such plates on sale.
Heating elements in the oven of a gas cookerare gas and electric. Recently, manufacturers prefer to produce models of plates, where the cooking surface is gas, and the oven is electric. This trend is caused by the fact that electric heaters, firstly, provide more uniform heating in comparison with gas heaters, and secondly, the temperature of electrical elements is easier to control. Heating in the oven, depending on the model, can be from below, from above, and also from above and from below simultaneously. In addition, there is infrared heating, convection (ventilation heating), a grill and all the combinations listed. When choosing an oven, it is worth paying attention to the presence of sliding rails for trays. This is necessary to ensure safety - there is less chance that you will burn yourself. It's also good if the oven door is insulated - in addition to the main glass there can be up to four layers of insulated glass, which also helps to avoid burns. Those who use the oven know that the process of cleaning it is not just an exercise. In inexpensive models of plates, there is no self-cleaning function, and it should be cleaned in the old fashion - with the help of special tools and wool. In new models of gas stoves, the internal surface of the oven is covered with special enamel, which ensures the catalytic cleaning of the oven walls: the fats decompose themselves.
If there is an incorrect use of gas,Many problems. Everyone knows what the gas leak in the apartment threatens. But even if there are no leaks, the gas stove can create other problems. If the burner is not set correctly, carbon monoxide, a toxic gas, can form. Therefore, the proper operation of the burners is very important. Whether the gas is completely burnt is determined by the color of the flame. If the flame is blue, then everything is normal. If the flame is low and burns with hissing, then there is more air than necessary, and if the flame extends upwards in yellow tongues with the appearance of soot, then there is not enough air. With the production of modern gas stoves, manufacturers take care of ensuring the right mix. We have tried to fully tell about modern gas stoves and hope that those who decide what to buy a gas stove will help understand the choice that domestic and foreign manufacturers of home appliances provide.
