Repair convection

Convection oven is considered a hybrid of iron, quartz heater, wind blower. Working together, will allow you to get mouth-watering delicacies that other methods would be difficult to prepare. We believe that the inhabitants of America adopted the technology of buffalo smoking from the Indians, then the frying methods were introduced into everyday life. The grill resembles a spit hanging above the fire. In fairness, let's say, infrared radiation makes a small contribution to cooking, the chicken turns red, tanned. It is much easier to repair the convection oven with your own hands than, say, an iron. The screws are not hidden skillfully made decorative elements, buttons, knobs. A repairable device looks more attractive in the Russian market than beautiful, but disposable.

Thanksgiving Day is celebrated in memory of those who survived the famine winter of the coast of colonized America. Assistance to the settlers was provided by the local Indian Tiskvontum, poisoned subsequently, according to the assumptions of historians, by militant brethren.

Typical aerogrill device.

The aerogrill grille plays the role of both an infrared emitter and a heating coil blown by a fan. The device has an infrared( halogen) lamp, serving as the primary source of heat. The cover is removable( start it when you need to repair the convection oven), the annular element is located at the bottom of the perimeter. Separated from the working compartment of the giant glass bowl by a steel lattice with an arbitrary shape of holes. If you take the repair of convection hotter, you will have to face another mechanism for lifting the hinged cover.

They said that the aerogrill device resembles an iron for one simple reason. The regulator is made according to the scheme based on a bimetallic plate. Of course, there are many constructions; they are powerless to list everything; simple devices are arranged like this:

• The compartment bowl is airtight. The top is supported by a quartz lamp supported by a cover, protected by a grille.
• At the level of the lid-bowl interface accounts for the lower fan blade. Unusual design. Formed by two squirrel wheels separated by a partition( tangential type).It is impossible to call each fan axial or tangential - something in between. The lower blades work by blowing food, the upper ones cool the engine. Do not forget, aerogrill has a long mode of operation, therefore, it is impossible to do without forced cooling. Both fans move the air down, tangential component out.
• Passing through the lids of the lid body, the flow enters, blows the engine, enters the sandwich gap between the chambers( food and technical), is thrown out, passing a number of slots. The stream blows a quartz lamp and a grating. The blades are not flat, like a tangential fan, bend at a slight angle, increasing the suction force. In the food compartment, air enters the center and is thrown onto a quartz lamp. In the partition between the blades a number of cracks. Two for the input of the electric cable of the quartz lamp, others are cut to remove excess pressure when cooking. Therefore, the situation when the lid is thrown off during warming up is excluded. Smacking the cup of aerogrill can be heard characteristic sharp thud. The blades are separated from the motor by a steel partition in which ventilation slots are cut.

• Fan operation is continuous, the glow of a quartz lamp is controlled by a bimetallic relay that adorns the steel partition separating the cooking compartment from the technical one. It is necessary because the streams, when the pressure rises, despite the efforts of the fan, go outside, clearing the way with grease and soot. The control copies the iron: the relay consists of a bimetallic plate that is activated when the steel partition reaches a predetermined temperature, a trimming bracket, controlled by the control panel regulator.
• Display system, control is simple. A pair of light bulbs, mechanical timer, circular knob temperature settings. Many have noticed: it looks like the Multi-cook multicooker mode. Choose a temperature, set the time, then the differences begin. In most trivial cases, convection oven is not an automatic device. The cook is obliged to conduct a visual control over the state of the prepared products. Allow roast meat to taste. Immediately make a reservation: those who refuse to turn the roast on the grid during the cooking process have no chance of getting a decent result.
• It remains to add: the cover has a folding handle with a secret. Raises - turns off the power to the device. At the end of the notch under the handle is a locking button, pressed down in the closed position. Without this, cooking will not start. You can interrupt the program in the right place, correcting or turning the pieces of meat. Be careful: inside the burning air.

Independent repair of aerogrillum requires knowledge of the internal structure. At the input of the electric circuit there is a switch pressed down by the handle. Through the timer the fan motor is powered. A relay is connected in parallel with the branch( regulated by the corresponding handle), a quartz filament lamp. For convenience, a couple of indicators:

1. Timer operation. The lamp is on while the cocked mechanism is ticking.
2. Quartz work. The lamp burns synchronously to the heating element.

Novices are interested in why indicators are needed. It will come in handy when the repair of aerogrill do it yourself becomes inevitable!

1. The quartz indicator is on, there is no heating, prepare five hundred to replace the spirals.
2. While the timer indicator is lit, the program is running. Even if the spring mechanism stops. In the rest position, on the contrary, neither the indicator should light, nor the quartz lamp to warm.

On the temperature controller you will notice the self-cleaning mode. Today, the popular word, convection oven without options could not do, of course.

In fact, nothing complicated. Inside the bowl is poured a bucket of water with detergent( dishware) so that the foam does not reach the fan. The timer turns on for 40 minutes. After the specified time, the quartz lamp grille and fan blades will become much cleaner.

The advantages and disadvantages of the convection oven

Why convection ovens work like this is a big question. Judge for yourself:

• Inside there is a quartz lamp, separated from the working compartment by a grille. Steel is specially equipped with thick ceilings, so that half of the radiation leaves the grid. Where does the rest go? Heats the table, floor, cook, ceiling!

This is not rational. It is known that the efficiency of a halogen lamp is 98%, if the light heats the room is not good for cooking. The aerogrill bowl is made of glass, stops ultraviolet radiation, not infrared. For the chef, of course, useful. Infrared radiation is used for the treatment, prevention, removal of postsyndromes in diseases of the nasopharynx. Feel the warmth of the convection lamp with a hand. Not convective heating! When the lamp turns off, the hand no longer feels warm. The only big drawback of aerogrill.

The device does not work automatically when cooking other dishes. Some will argue: multicooker is not omnipotent. However, the main recipes are automated. Over the side will have to try. In conveying ovens, the dominant advantage is the advantage of getting roast without oil. The main dish will not be prepared automatically. The cook should monitor the action of aerogrill, at the right time turn the meat on the grill. In the recipe book, the moment is missed, the chicken is not prepared, lying on one side. Top roast baked shock, bottom gets a little heat.

Malfunctions of aerogrill

From the above it is clear that it can break:

1. Blown quartz lamp.
2. Fails engine.
3. Breaks down the relay.
4. Failed timer.

Main types of faults. Convection oven regularly cleaned.

Disassemble the convector

Begin should grate quartz lamp. Then removed the lower blades, the partition. Removing the top "squirrel cage", we get access to the wall of the motor compartment. Behind her stuffing device. Quartz lamp is attached to the partition with brackets. Cable connectors are removable, it is better to dismantle, do not touch the metal fasteners. Unless, of course, you do not need to replace the quartz lamp.

The convection oven is not an iron, however the screws may be hidden under the decorative elements. First handles. In many models, screws are hiding under the quartz lamp grille. Steel blades are held on the central nut. Do not hold when disassembling. On the back of the blades there is a nut to grip, or the disassembly is not made from this side. In the master's course, some readers will ignore the words - in case of a successful experience, write in the comments.

We hope that now the readers of the VashTechnik portal can repair the Hotter convector, repair the Ves convection oven, which are similar. Cook shish kebab, chicken. It turns out great, enters the mouth of the better: om-nom.
