Barbecue - an indispensable thing in a country house. Rest with the preparation of barbecue is one of the most popular in our country. It is not only delicious, but also a whole ritual for men. Therefore, so that the rain does not spoil the rest, the zealous owner will provide a barbecue device under a canopy or directly in the gazebo. But here another problem arises - smoke. To eliminate this difficulty, you can not do without a hood for barbecues .
Indications for use
There are two main types of barbecue: stationary and portable.
The first requires a solid construction. The second is most often presented in the form of a metal mobile device. If the use of the barbecue is provided for indoors, then smoke and burning will be required to maintain a comfortable environment in the recreation area. In this case, a hood for the barbecue is mounted in the gazebo.
Models can be sold both complete with certain types of basic equipment, or separately. You should consider in more detail the design features of these devices.
Classification
You can divide the hoods for barbecue into several groups:
- according to the material of manufacture: metal and brickwork;
- by options: simple and with additional elements.
Such devices are sold and even made to order, but it can take a lot of time.
Much more pride will be caused by the do-it-yourself barbecue and the exhaust device to it. You should consider the main components and the assembly process of each type.
Device
The design of the exhaust hood for barbecue facilities does not have any complex nodes and is:
- umbrella for collecting smoke, burning, fat. Performed in the form of a dome, may take the form of a parallelepiped or a truncated pyramid. These canopies can be with forged elements and be part of the interior design of the gazebo. Such a grill with an extract photo clearly demonstrates;
- chimney designed to remove smoke.
As you can see, there is nothing complicated in such devices, but still there are a number of subtleties that are worth knowing.
Device features
First of all, it should be remembered that the hood hood for barbecues should exceed the area of the equipment over which it will hang. This will provide greater smoke collection efficiency.
The chimney should narrow and have a bend. This will improve the exhaust speed of the combustion products and prevent the possibility of back draft. The top of the pipe must be at least three meters above the ground. This will create good exhaust conditions.
If you incorrectly calculate the cross section of the chimney, you can get an inefficient system of removal of combustion products.
Additional elements increase the efficiency of the exhaust structure, but at the same time affect the price. There are a number of such elements:
- spark arrester. Mounted on top of the chimney. It is a metal sieve in the form of a pipe through which smoke freely escapes, and sparks are extinguished;
- grease trap. It is a frame into which a removable cartridge is inserted for the process of trapping fat. When contaminated, it either changes or is washed, depending on the model and the filter medium itself;
- fan. This device increases traction.
As you can see, the device itself is not a technically complex product. But it is important to consider and correctly calculate the parameters of the required equipment.
Metal cooker hood
It is precisely such a plan for the device that is most widely used for installation in the gazebo. Metal exhaust umbrellas can be purchased ready-made, unlike brickwork. Some companies do even for individual orders. But if standard models do not fit, and custom execution is delayed in terms of time, then a cooker hood made with your own hands will be a simpler and faster solution to the problem.
For work, metal 2 mm thick is required.
The length of the middle chimney is from 850 mm to 1500 mm, width from 650 mm to 900 mm. These sizes depend on the dimensions of the barbecue. Do not forget that the perimeter of the hood should be larger than the equipment over which the placement is planned. The pipe is made, as a rule, of a square section with parameters from 250 to 280 mm and a length of 2-3 m.
You should first complete the drawing or select the appropriate one on the Internet. Cut the metal using a grinder and a cutting wheel for metal. Next, weld and assemble. A hood for the barbecue in the gazebo is located in the center. Fastenings can be carried out on racks, and for insurance use additional chains. To protect the pipe from precipitation, a visor should be provided.
Standard umbrellas are made of stainless steel, which significantly affects the price of equipment. Do-it-yourself hoods can be made of any heat-resistant metal, but before use it is necessary to cover with heat-resistant anticorrosion varnish, which will increase the service life of the product.
How to make an extract for a barbecue from metal was considered, you should study the manufacture of structures from brick.
Features of brick hood
This option requires some knowledge. This type of hood is made for stationary brick braziers. The brick must be refractory (fireclay). The solution is clay with sand, while clay should be soaked for 2 days. The proportion of sand in the solution should not exceed 50%.
For the foundation of the brick hood, a frame should be provided on which the brick will be laid out.
Treat it with refractory enamel, as it will be exposed to high temperatures. The frame is fastened with barbecue fittings by welding.
Brickwork masonry
The first row is laid out in jerky (the push is the shortest side of the brick), the rest is put in the spoon (long sidewall). The standard smoke box consists of 10 rows. Moreover, the laying is carried out with a narrowing. On the front, a row offset of 17 mm per level is allowed, along the end part it is 35 mm. Next, a square tube is laid out (five more spoon rows). The upper part should be a cross-section of 260 * 260 mm. This configuration enhances the exhaust effect. You should also provide a valve, and on top - a visor from the rain.
After the construction is completed, time is given to dry the masonry.
Next, the device is coated with refractory varnish in 3 layers. This will ensure a longer operation of the equipment. As you can see, a brick cooker hood made by yourself is a rather complicated process. Better to trust the professionals.
The benefits of homemade hoods
Both types of equipment have a number of advantages:
- DIY installation will significantly reduce the price of hoods;
- an opportunity to make according to the individual size and in accordance with the design requirements.
The metal hood for the barbecue in the room has a number of additional features:
- light weight construction;
- the ability to install additional options;
- quite easy installation;
- mobility, if necessary, can be mounted in another place;
- ease in leaving;
- low price.
For brick hoods, one can distinguish an indisputable advantage - durability, as well as the possibility of reconstruction. However, to transfer such a design from place to place is unlikely to succeed.
Operational Features
If the equipment is not monitored, exhaust performance will decrease over time.
Dirt and soot will begin to fall on food that is in the barbecue. Therefore, periodically clean and flush equipment. The first indicator to clean is visual contamination and reduced traction. It is not in vain that it is recommended to cover products with protective enamels and varnishes. This greatly facilitates the process of caring for this design.
The question is often asked: “Why does the smoke at the moment of ignition not go through the hood?”. This is based on the physical properties of air. At the time of ignition, it is not yet heated enough to rise up. With increasing temperature, this draft is normalized.
Equipping a country house and cottage, I want to do a lot with my own hands. As you can see, hoods for the barbecue can be mounted by yourself, as, in fact, the barbecue itself. One has only to set a goal and decide which type of structure is preferred. And if design thinking is still developed, then the resulting designs will give odds to the products of many professional companies with extensive experience in the construction of such devices, and will become a special subject of pride before the guests.
So, we have figured out how to make our own hood for the barbecue.
