Ventilation in the house. How to automate the kitchen hood with your own hands

In a modern house or apartment, it is difficult to find a kitchenette, which would not be equipped with forced exhaust ventilation. Moreover, the extracts are used different, from simple fans that are inserted into the window window to complex turbine systems that can clear the large amount of air in a few minutes. Extract models are also divided into replete air into the ventilation channel and filtering it. The latter do not have air ducts than noticeably save space. However, they require constant replacement of filters.

Ventilation in the house. Ready solutions for extractors

The main purpose of the exhaust is a removal or air filtration in the kitchen during cooking. During this process, the room is filled with carbon monoxide gases, steam, the temperature in it rises. All these factors do not likely affect kitchen furniture, ceiling, walls. That is why the work of the drawing during this process is obligatory.

It is worth remembering that the higher the performance of the drawing, the more it consumes electricity. On average, the power consumption of this apparatus is 1500-1700 watts per hour, which is not quite small. However, the device should only work when the air temperature above the slab reaches a certain temperature. During the rest of the time, the work of the hood does not make sense. This mode of operation can be achieved by automation.

How to make the repair of kitchen drawing with your own hands with automation and more about the characteristics of these aggregates - further in the article.

The leading manufacturers of kitchen appliances have long thought over the automation of exhaust work. So, Siemens offers its consumers a rather original solution. A set of exhaust and cooking surfaces have radio modules that synchronize their work. When the cooking surface is turned on, it gives an exhaust signal, so that it turns on. When you turn off the burner, extractor hood goes into low-performance mode, and then just shuts down. The disadvantage of using a radio signal is that when even a small contamination purity signal weakens and synchronization of devices may be compromised. Therefore, they must be kept completely clean. Also, the work drawing on the early stages of cooking can be meaningless.

To solve the problem of automatic inclusion of extracts, Krona company released a series of extracts from the Intellect Start system. When the device is switched to the automatic mode activated air analysis sensors. When the concentration of the vapor in it above the limit value, it is included. If the vapor content in the air will increase the intensity of the fans will increase.

Fair to say that such extracts models are quite expensive, so you should try to make the automation of conventional hoods with their own hands.

Ventilation in the house. Upgrading an existing drawing

The procedure for work to improve the existing drawing:

1. Works on the change in the drawing design must be carried out only on dismantled equipment. To do this, it is removed from the attachments, be sure to disconnect from the duct and power supply.
2. Then the design is taken. The first thing is removed the grease filters for kitchen drawing with their own hands, then coal. After that, you can temporarily disconnect the electric motor. It can still be postponed.
3. Next, you need to check the electrical circuit for the presence of a signal lamp. If there is no one, the hole is drilled under its installation. As an indicator, you can use voltage lamps with voltage 230V, or IEK AD16DS type indicators, or their analogues.
4. At the bottom of the housing, it will be necessary to drill another hole for the installation of the temperature sensor. In order for it, the fat does not fall, for the hole it is worth providing a cap. For this purpose, a furniture plug is perfect. The cap thickness should be as small as possible in order not to distort the operation of the sensor itself.
5. In the back of the housing, the housing or DIN rail is installed for installation of automata, and you should also drill a few holes for the supply of wires.

Ventilation in the house. Preparation of air ducts

At this stage, you should take advantage of several tips:

• As the main electricity duct, corrugated aluminum pipes are used. They are easy to handle, have a small weight, can increase almost 25% in length. Standard internal diameters of corrugated nozzles are 125 and 110 mm.
• When installing the air duct, it is necessary to take care of the tightness of the compounds. If there is a "sucking" of air in the connection places nozzle with an exhaust flange, its efficiency will noticeably decrease.
• Fastening the nozzle to the flanges is performed using plumbing clamps. For a more sealed connection, a silicone sealant can be used. When installing the kitchen drawing with their own hands in a private house you will have to do the air duct pipe. Here it is necessary to remember that, the higher the pipe, the better the thrust.
• For the construction of the outer part of the air duct, plastic sewer tube is perfect. A protective fungus is installed in the upper part of it in the upper part of it. The pipe diameter should not be less than the diameter of the outlet of the exhaust.
• When installing the hood in the apartment, the air duct is displayed in the sower space with the installation of a special flange.

Ventilation in the house. Working with exhaust fan

Usually installed in the fan extract, it turns out to be enough to ensure the normal operation of the ventilation system. Especially if the centrifugal fan is used, the so-called turbine. If the power of the standard fan is not enough, you can replace it with a more powerful one. Make it in most cases it turns out to be problematic. Wine all over the size of the nozzle, because for the exhaust with the diameter of the outlet 110 mm is quite difficult to find a powerful fan.

By solving the problem of increasing the power of the exhaust, the installation of an external axial fan in the duct canal can be. The inclusion of them can occur in parallel. If the external fan is highly powerful, then you can remove the factory and leave it only. An increase in the pulp power will make it more efficient even with a large amount of cooking. If desired, it can even be raised above the cooking surface. When installing in a private house, you can endure the fan beyond the placement. This will noticeably reduce the noise and vibration with increasing its power. However, the cost of such a solution will be slightly higher.

How to make automation of kitchen drawing with your own hands

When all the elements of the future exhaust system are selected, you can begin to automate it. The basis of the automatic exhaust ventilation system will be the digital controller "Rubezh" TP-16.01. It also applies to the automation of heating boilers. The controller is installed in a pair with an automatic voltage of 6 amps. Such protection is enough to ensure the safe operation of the electrical circuit. The machine must be a bipoly.

In the thermostat scheme, several terminals are provided:

• Power - connects to the machine and gives electrical current on the controller relay.
• Connecting the sensor. In this case, the temperature sensor is connected to the controller, which will transmit information to it.
• Relay output. It is intended to supply power to the network when the controller is triggered.

Procedure for work:

1. Power on the controller is supplied from the lower pole of the machine, and the jumper of the central contact input of the relay is connected to it.
2. In order for the exhaust to be enabled forced, its switch is connected parallel to the relay contact to which the engine is connected. This contact is called normally open.
3. The second fan motor wire is connected to the opposite of the terminal of the machine to which the jumper is connected.
4. The thermal sensor is installed in the cap on the housing of the hood. In the cap, you must pour the CTP-8 paste and gently immerse the sensor into it. Before this, the heat shrink tube, which is installed at the end of the sensor, must be accurately removed.
5. Pasta must chase a couple of hours to frozen. Prior to this, the sensor is not desirable.

Setting the kitchen hood controller with your own hands

Including with a thermostat relay (controller), an instruction must be followed, in which the connection schemes and the instrument setup steps must be described. When configuring the controller, it is necessary to take into account the fact that the temperature sensor triggers a bit with the intake. This is due to the fact that its metal shell should warm up on the title temperature.

When the gas stove or the hob in the mode of slow fire, the air under the exhaust is heated to 50 ° in less than a minute. Given the late sensor response, the exhaust can turn around in about a minute or two. During this time, the air warms more than necessary. Therefore, when setting up the controller, it is necessary to install a response temperature by 8-10 ° C below than the specified one. Suppose you need to set the boundary temperature at which the extract should be turned on at 45 ° C, then in the controller you need to set the temperature not more than 35-37 ° C.

The bottom temperature at which the extract should be turned off, is set as the temperature difference or "hysteresis". For example, if the pull on the exhaust occurs at 37 ° C, and the shutdown should occur at 30 ° C, then the size of the hysteresis should be at 7 ° C. The programming of the automation is made by the "B" buttons, as well as "↑" "↓". To set the inclusion temperature, press the "B" button for 3 seconds, and install it using the arrow buttons, securing the result with the "B" button. The hysteresis is installed in the same way, only first the "B" button must be kept for 5 seconds.
