It is difficult to imagine modern life without kitchen appliances - with its help we cook dinner, bake pies, store food, indulge ourselves with fresh coffee in the morning. And among the numerous equipment stands out a stove that has successfully replaced at one time a home hearth - a stove.

The population of gasified territories living in low-rise and private houses uses gas-fired stoves. If this tireless assistant has also settled in your kitchen, we suggest that you figure out how the gas stove works, what parts it consists of and how to increase its life.

Our tips will help you take care of the equipment and respond correctly if it fails.

Design and principle of operation of the gas stove

If you use cooking equipment daily, you know very well what parts it consists of and how it works.

In their structure, all gas stoves are very similar, and the differences relate to the design or design features associated with additional functions.

The scheme of the gas stove

Modern manufacturers specializing in the manufacture of kitchen equipment, are trying to diversify the model range due to the more convenient location of burners and control panel, internal filling of the oven, introduce electronic filling.

At the installation site, gas stoves are divided into outdoor and tabletop. The latter is more often used as a summer residence or temporary option. Also emit autonomous cooking surfaceswithout an oven that can be built into the countertop.

Built-in gas appliances in the kitchen
Built-in appliances have earned popularity among users with ease of installation and operation. The stove and oven can be placed in different places, which is very valuable with a lack of free space

But you need to consider that the simpler and more primitive the design of the plate, the easier its maintenance. Inexpensive equipment, which is often purchased for installation in cottages, lasts a long time - there is no electronics in it, and parts that can break down are always easy to replace.

Overview of the main elements of a gas stove:

In addition to these elements, more complex and expensive equipment has additional details. it electric ignition unit and electronicsregulating the operation of the oven.

The latest models are produced with a pre-installed gas leakage control system: if the flame accidentally goes out, the fuel supply instantly shuts off in automatic mode.

We consider in more detail the elements directly involved in the workflow.

Hob structure

Nobody calls the top plane with hobs located on it now a “table”, more often they use the name “stove” or “hob” - if we are talking about built-in appliances. This is the element most often involved in the cooking process, and therefore requires regular care.

In low-cost models, the upper plane, like the entire case, is coated with enamel. If it looks attractive with a new product, then in the future the appearance of enamel deteriorates significantly: cracks and chips appear that complicate care.

A stainless steel stove also needs careful care. Matte or glossy surfaces do not like to be rubbed with metal brushes.

Plate Cleaner
If you need to remove dried dirt or hardened fat, it is better to use household chemicals to clean the metal: a special gel, cream or spray

Abrasive products in the process of caring for kitchen appliances should never be used.

Well, the main working elements on the hob are still the burners, which, if used improperly or poorly maintained, can quickly fail.

How is a gas burner arranged?

In household appliances, flame injection multi-torch burners are used. The principle of operation of any gas stove is based on the combustion process that occurs after mixing fuel with air.

According to the device, the gas stove burners may differ, depending on the features of the models and the possibility of adjusting the flame, but the main details are present in all products:

  • nozzleperforming control over gas flow at operating pressure parameters;
  • diffuser (with or without a gate), in which the gas is mixed with the primary air;
  • body - the chamber where the process of mixing gas with air ends.

The gas-air mixture is discharged into the combustion zone through openings that are located around the circumference of the upper edge of the burner.

Slotted fire holes on top are covered with a steel cover that performs protective and distributing functions.

Flare burner cap
A flange is made along the edge of the lid, which is responsible for the fluency of the spread of the flames of the flame and for the stabilization necessary to protect it from tearing

The general structure of burners for domestic gas stoves designed to work on propane-butane is slightly different from analogues for natural gas.

Despite the strict rules for the production of gas stoves, the requirements for efficiency are not so high - only 56%.

When burners with a pilot flame appeared, some elements of the burners were considered inappropriate - for example, a gate. Instead of a gate, two holes at the inlet end of the mixer are responsible for injecting primary air.

Oven device

The oven is designed for baking dough products, baking meat, fish, vegetables, etc. By design, it resembles an ordinary cabinet, but the shelves are made in the form of gratings that do not impede the free circulation of heated air.

Shelves in the oven
The filling of the oven can be adjusted by moving the shelves higher or lower, replacing them with trays or special devices for baking or grilling

To maintain the necessary stable heating, it is equipped with a gas burner that is different in design from the burner burners.

The heating itself is due to circulating hot gases.

Oven circulation
Air flows can move in different directions. It depends on the location of the gas burners inside the cabinet - from the sides, top or bottom

In modern models, one of the frying burners is located in the upper part of the cabinet, which contributes to the baking of products from all sides. The upper arrangement is also characteristic of ovens with the grill function.

In domestic stoves installed burner disc type with a pilot flame.

The main burner, which is usually set on fire manually or automatically, is equipped with thermocouple and ignition tube. A radiator with a screen is installed on the frying top burner.

Backlight in a gas oven
Almost all modern models are equipped with a backlight, which greatly facilitates the use of the oven and allows you to observe the cooking process with the door closed

For our own benefit, we recommend that you learn more about the device of the gas stove oven - this can come in handy for minor self-repair or choosing new equipment.

It must be remembered that the process of using the oven is accompanied by the implementation of the rules. For example, you can’t open the door while cooking - this dramatically reduces the temperature and affects the baking process.Do not leave extra shelves or dishes in a working oven - this also negatively affects the result.

The typical design of the stove also involves the presence of a drawer under the oven, the purpose of which can be found in of this material.

Electrical control and monitoring system

In the cheapest stoves, electronic control is not provided - the whole process is regulated mechanically. More expensive models connect an electrical system to enable functions. electric ignition and lighting ovens as well skewer control.

Gas stove electric ignition elements
The design of plates with electric ignition includes candles located on the divider body. They instantly work when turned on, that is, at the time of gas release

Some users are so used to the auto ignition system that they get lost when the power is turned off and do not know how to turn on the gas. This is done simply: the control knob must be put into working position, and then quickly bring a lit match to the divider.

The backlight function works in different ways: in some ovens it is turned on by pressing a button, in others it is switched on automatically, each time the oven is turned on.

Very useful gas control, whose work is carried out by a thermocouple.

Thermocouple in the construction of a gas stove
The main purpose of the thermocouple is to shut off the gas supply if the burner flame goes out for any reason. Principle of work: the fire disappears, the temperature drops sharply, the gas automatically shuts off

The most expensive models are equipped with electronics, which facilitates both the cooking process and equipment care.

Using the panel with buttons and display, you can control all processes, among which may be the following:

  • timer;
  • delayed launch;
  • steam oven cleaning;
  • several cooking modes;
  • light and acoustic alarm;
  • electronic temperature control;
  • quick cooling system, etc.

If the stove is inexpensive, but provided with electronics, you should ask yourself the question: how often will you have to contact a service center? Because electronic equipment, according to statistics, breaks much more often than usual.

Cooker Selection Criteria

Consider the features of gas stoves that do not relate to their technical characteristics, but relate exclusively to the design.

Design, content, arrangement of elements are no less important than power or the number of operating modes.

Portable gas stove with cylinder
If you are interested in a device for seasonal use in the country, do not even go to the department of expensive equipment - a portable stove with a gas cylinder will satisfy your needs and will last a long time

For continuous use, you must choose a reliable functional unit of a proven brand. To do this, you can read reviews and reviews, in large quantities posted on the network.

When buying from a design point of view, pay attention to criteria such as:

  • dimensions of the stove in general and the hob in particular;
  • oven volume;
  • set of accessories for the oven;
  • control panel location;
  • the location of the pipe for connecting to gas;
  • the possibility of replacing burners for operation with bottled gas;
  • number and size of burners.

Any unaccounted for trifle in the future can cause discomfort and dissatisfaction with the work of the stove, so try to think through everything in advance.

Rules of operation and repair

Serviceability of the equipment and your personal safety largely depends on how you feel about the equipment. This includes proper installation, gentle operation, regular maintenance and replacement of parts with a limited lifespan.

Here are the basic rules for using a gas stove:

  • regularly clean the grate, surface of the stove, burner, control knob;
  • keep in touch with representatives of Gorgaz and regularly carry out technical maintenance;
  • ventilate the room, even if using a hood;
  • in case of prolonged absence, close the shut-off valve;
  • make sure that the handles are in the “off” state while the stove is not in use.

Care must also be taken in the operation of the oven. He, like any equipment, requires the cleanliness and serviceability of all parts.

They do not recommend using the oven as an ordinary cabinet for storing dishes, especially cluttering it with easily combustible or melting objects.

Filling a gas oven
Inside the oven there should be only “working” accessories: baking trays, wire racks, grills and utensils, or molds if they are involved in cooking

If ventilation is faulty and it is not possible to open a window or window, it is forbidden to use gas equipment.

If there is a specific smell of gas, it is necessary to turn off the fuel supply valve, open the windows and call the emergency service. During the waiting period, you can not turn on electrical appliances, light a flame, but it is better to completely leave the room. Even a call is recommended to be made from the landing or from the street.

Repair of gas equipment must be handled either by invited specialists from the service organization, or by employees of a specialized service center.
