Classification
There are many manufacturers producing air purifying devices, offering models with a variety of functional equipment.
Separation by type of construction
- Island
Island-type appliances are installed above slabs located not against the wall, but in the central compartment of the room.
- Corner
As the name suggests, these hoods are designed to be installed in the corner of a room.
- Built-in
Compact devices that fit into a kitchen cabinet that hides the ventilation pipe.
- Wall mounted
Common and efficient devices with a favorable price-quality ratio.
Division by job features
Resembles the shape of a pyramid.
Depending on the specific features of the work, hoods are divided into:
- Circulating
Budget options for air purifiers operating on the recirculation principle. Not connected to the ventilation system. The devices are equipped with special filters through which harmful particles are removed from the air.
- Flow-through
Polluted air is drawn out of the room through the ventilation shaft. The devices are characterized by the highest level of purification. An example of such an air purifier is a fireplace hood.
What is a fireplace (dome) hood
A fireplace hood is an air purifier whose design is similar to the design of a fireplace exhaust system. Polluted air enters the dome housing and then exits through the duct into the ventilation system. Thanks to its spectacular appearance and unusual design, the device often becomes part of the interior design. Fireplace hoods are divided into wall, corner, island and inclined.
Advantages
The shape of the church dome
The widespread use of the device is easily explained by its positive characteristics:
- Nice appearance
When purchasing some air purifiers, owners plan to disguise the device and the exhaust pipe. However, with this device the need for disguise disappears by itself. The dome-shaped shape of the device fits perfectly into any environment, turning kitchens with fireplace hoods into a stylish and comfortable room.
Additionally, some types of dome air purifiers can be used as a shelf to display various kitchen items.
- Efficiency
Dome hoods are flow-through devices with high performance. Most are equipped with two motors and reusable filters. Even the most “modest” attachment has the necessary list of functions.
- Easy to install
Installing a dome air purifier does not require highly professional knowledge. The device is fixed to the wall with self-tapping screws or dowels.
- Affordable price
The cost of a hood depends on functionality and varies widely. This characteristic allows you to choose a suitable device at an affordable price.
In addition, a fireplace hood is considered a worthy alternative to a standard chimney. The device can be mounted in any convenient place and has several operating modes.
Performance
Black exhaust filter
The first thing you need to know when choosing equipment is its performance, that is, the volume of air that the hood can process in a specific time.
When determining productivity, the volume of the room is multiplied by the air exchange rate.
To determine the volume of the kitchen, find its area and multiply by its height. You can get more accurate information if you subtract from the found value the size of the space occupied by kitchen furniture.
The air exchange rate is characterized by the number of air flows within 60 minutes. The average is 12.
For example, you need to calculate the efficiency of a device for a room 3 meters wide, 4 meters long and 2.8 meters high. It turns out 3x4x2.8=33.6 cubes. Accordingly, the productivity of the equipment is 33.6 × 12 = 403.2 m3.
When choosing a hood, it is better to choose options with a decent performance reserve. If you frequently turn on the device at maximum power, this will negatively affect the operating time. In addition, when very busy, hoods make quite a lot of noise.
Dome hoods are mounted on the wall or on the ceiling above the stove.
The performance of the device is affected by kinks in the ventilation pipes. On average, one 90-degree turn reduces the quality of equipment performance by 10%. In addition, the hood will work worse if the filters are dirty.
It must be said that the above calculation of productivity is not entirely correct. In rooms with a small area, the accumulation of harmful substances occurs quite quickly. In this regard, it is better to purchase equipment with productivity exceeding the calculated parameters.
Step-by-step instruction
- In accordance with the manufacturer's recommendations, the installation height of the hood is determined. The marking is done directly on the wall: a horizontal line is drawn at the required height, the evenness of which is measured using a level.
- The height of the device is set. If the indicators show that the hood is longer, then the pipe is cut off, since it is strictly forbidden to install the hood below the required height.
- Measuring work is carried out to determine the mounting locations on the wall. Such points are fixed on the wall.
- In accordance with the “beacons”, holes are drilled into which dowels are inserted.
- The hood is fixed to the wall from the top using screws. Only after complete alignment is the hood fully secured.
- The exhaust pipe is connected to the chimney.
Important! Install a check valve on the exhaust vent, which will prevent exhaust air from entering the room.
Dimensions
A fireplace hood for a kitchen should fit the dimensions of the stove, that is, their dimensions should match as much as possible. The air purifier can be wider than the stove. This will capture all air flow contaminated with harmful substances.
The most optimal ratio is considered to be the option in which the dimensions of the hood are slightly larger than the dimensions of the hob.
The most common devices are air purifiers with a width of 50 and 60 cm. There are also other sizes of hoods: for example, 90 cm.
Noise magnitude
The maximum noise level should not exceed the human speech level. The noise level of the device when running at full capacity should be 60-70 dB. The average level is comparable to muffled human speech and is 40 dB.
Fireplace or dome shapes are ideal for island-type kitchen interiors
Is your kitchen hood noisy? Check the cleanliness of the filter element. Most often, it is an ordinary porous fabric, which, when dirty, affects the operation of the fan, which begins to vibrate and make noise.
Cleaning the fan will help reduce the noise of the kitchen hood. To do this, use a cloth soaked in a degreaser or solvent and machine oil, which is used to wipe the rubbing parts.
Equipment with a pair of fans is quieter. In addition, hoods with a more powerful motor are characterized by lower noise levels.
Exhaust filters
There are two types of filters, these include:
- Internal. They are able to cleanse the air of unpleasant odors.
- External. Retains soot and grease.
On expensive models, grease-repellent filters are installed, which practically do not need to be washed. In cheaper designs, filters become dirty after 3-4 months and are quite difficult to clean.
If you notice that the air is not cleaned when the hood is turned on for a long time, this means that the hood filter is dirty and needs to be changed urgently.
Installation
Installing a fireplace hood in the kitchen with your own hands is a task that a home craftsman can handle. The main thing is to choose the right device and carefully read the instructions. A good manufacturer should highlight the conditions and parameters necessary for installing a specific wall-mounted hood. They must match the size of the kitchen space. Otherwise, the product will not be able to be installed correctly, which means its operation will not be correct. For example, the wall-mounted kitchen hood LC958WA60 is fixed at a height of 55 cm from an electric stove and 65 cm from a gas stove. And the White Storm 60 air purifier is mounted 10 cm higher in both cases.
The front panel is made of glass
It is precisely such nuances that you need to pay attention to. If you hang the hood above or below the established requirements, it will either burn out or be useless.
The installation of an air vent has its own nuances:
- A sealed throttle valve is installed on the air channel. When the wall hood is not in use, this passage is closed, preventing warm air from leaving the room.
- A grille is placed on the entrance niche.
- You should not run a duct from the basement, as an unpleasant odor may emanate from there.
- It is recommended to install the air vent on the windy side. Air currents will discharge the channel space and draw out all unpleasant odors.
Properly arranged ventilation guarantees good functioning of the hood. The temperature of the air leaving the device should not exceed 80 degrees. If installed incorrectly and with poor ventilation, the level can rise to 180 degrees, which will lead to overheating of the housing and a fire hazard.
To install a fireplace hood in the kitchen you will need several tools:
- Screwdriver;
- Electric hammer drill;
- Durable tape measure;
- Building level;
- Fastenings (screws and dowels);
- 2 hammers with different sizes.
How a kitchen hood works
Installation sequence
The dome hood is secured in several steps:
- Determine the exact boundaries of the location of the device from the source.
- Use a pencil or marker to mark the location where the hood will be installed.
- Mark the fixation points for the screws.
- Using drill number 8, make holes for screws with a depth of at least 5 cm.
- Fix the dowels in them.
- Carefully screw the screws into the 2 upper dowels and install the hood on them.
- Check the quality of fixation.
- Drive the remaining screws through the back panel.
Duct selection
There are several types of kitchen air ducts for household ventilation:
The plastic air duct is more compact and inconspicuous
- PVC plastic air ducts are durable, lightweight and silent, as they create almost no air resistance due to their smooth surface. There are both rigid narrow plastic boxes and elastic pipes.
- Corrugated aluminum pipe is a fairly simple material for DIY installation; it can be freely bent to the desired size. Another quality of corrugation is the absence of hum or vibration, unlike rigid boxes. However, an important drawback of such an air duct is its unsightly appearance, so figure out where to hide the ventilation, for example, in a plasterboard ceiling.
Service
The service life of an air purifier depends on the care of the device. The main thing you need to monitor is the condition of the filter elements, which are divided into three types:
- Disposable padding polyester. Made from paper or non-woven fabric. Such filters have special marks that are clearly visible through the protective grille. Their disappearance indicates the need to replace the grease trap.
- Reusable acrylic. They are washed monthly in soapy water without squeezing too hard.
- Reusable aluminum. Once every 30 days, clean with a degreaser or wash in the dishwasher separately from cutlery.
Purified air in the kitchen space from combustion products and unpleasant odors.
Quality control of filters is necessary not only to increase the performance of the appliance. Concentrated grease may cause the element to catch fire, so periodic cleaning is required to ensure fire safety.
You need to take care of your kitchen hood regularly. This will extend the service life and get a high cleaning result. Caring for the device consists of several stages. First, the hood is disconnected from the power supply. Then disconnect the grease-absorbing filters and wash all accessible parts. It is not recommended to use abrasives, sponges or scourers with hard cloths. The buttons on the control panel are wiped with a damp cloth. The last step is to wipe all the elements dry with a napkin and connect the hood to the power source.
Cleaning and care
Due to the rapid contamination of the mechanism, the equipment must be cleaned of fumes once every 2 months, otherwise a fire may occur. This process involves cleaning the kitchen hood filter and treating the external surface of the equipment with cleaning agents or soap solutions.
Grease filters are changed once every 3 months. Carbon elements are disposable, so they are completely replaced once every 4 months.
Despite the fact that the hood does not have a complex device, sometimes problems arise with its performance. In these cases, it will be necessary to make minor repairs to kitchen appliances.
Manufacturers
Among the variety of models of air purifying devices, Italian kitchen hoods stand out. For example, devices are characterized by low noise levels, excellent filtration, low energy consumption, fire safety and attractiveness.
WATCH THE VIDEO
Thus, air purifiers have long ceased to be luxury items. Compliance with the installation and maintenance rules for dome devices guarantees clean air and maintains a healthy indoor climate. A kitchen with a fireplace hood turns into a safe and cozy space with a decorative design. A fireplace hood for the kitchen is installed.
Practical purpose
A fireplace hood is, first and foremost, safety.
Fireplace hoods provide:
- optimal air composition in the room where the fireplace is installed;
- elimination of condensate formed during the combustion process;
- removal of harmful substances formed during the combustion process.
The hood is installed when the fireplace is created or when the room is being renovated. With this approach to the event, it is easiest to hide structural inconsistencies, if any.
Important! When installing an exhaust system for a gas fireplace, the creation of a chimney is mandatory. But, since the operation of such a fireplace is not accompanied by the formation of soot, narrower chimney designs with two turns can be used.
To create draft when installing a chimney with turns more than 2 times, it is necessary to install a forced ventilation system.
