With the onset of the summer season, there is a need for a cooling device. In such a situation, a floor fan comes to the rescue, which is designed to provide complete comfort and cool the air in the room.

Device and principle of operation

Floor fans for the home are considered the most famous and common designs for air cooling. The devices consist of a reliable base, a leg, a motor, a shaft, an impeller, a casing for closing the blades. The height of the structure is regulated by a foot, which is not found in similar tabletop devices. The fan has blades that are twice as long as the desktop ones. This increases the cooling efficiency of the room.

The floor fans are equipped with asynchronous motors with 8 stator windings . When the device starts up, a phase shift occurs at a right angle, which is provided by a capacitor. When the corresponding button is pressed, the indicator lamp lights up and the motor starts. Its rotation speed depends on the winding circuit, which can be changed using the speed switch.

Classification

Depending on the principle of operation, several types of devices are distinguished.

• Axial devices . The most common type of fans that have a motor with an impeller rotating in the same plane.
• Radial devices consist of blades of a spiral shape. The air mass enters the rotor, from where it moves along the radial axis and, due to centrifugal forces, is discharged into the outlet pipe to the cooled zone. Such fans cool the air with a certain pressure force.
• Bladeless devices - the most modern models that have a round shape. The principle of their operation is as follows: on the vertical base of the fan there is a turbine, which is necessary to take in the air flow, after which it gives it some accelerating force. Pressurized air comes out of the mold cracks. Continuity of the air flow is created due to the intake of adjacent air layers. Thus, bladeless machines are extremely safe.

How to choose?

When choosing a floor-standing household cooling device, it is necessary to take into account its technical characteristics. Adhering to certain recommendations, you can choose certain parameters that are suitable specifically for your apartment.

• Blade dimensions , on which the efficiency and the blowing zone depend. This parameter is typical for paddle room fans. Optimally recommended blade sizes are in the range of 10-16 cm. It must be taken into account that these parts of the fan must be protected by a casing.
• Power characteristics depend on the area of the refrigerated zone. For a small room, a power of up to 60 W will be enough, for large rooms, units of up to 140 W.
• Air strike - parameter influencing the speed of room cooling. It depends on the overall dimensions of the blades. For example, if this value is 5 meters, this means that the cooling unit will cool at a maximum distance of 5 meters. Therefore, it is necessary to select a fan on a high metal leg with an air blow that is suitable for your room.

• Air exchange , or productivity, shows how many changes of air flow are possible. Depending on the purpose of the room, there are air exchange rates. So, for bedrooms it is 3, for a kitchen - 15, bathrooms - 7, toilets - up to 10, and living rooms - up to 6 units.
• Tilt angle - a parameter characterizing the ability to rotate the blades from top to bottom, which reaches 180 degrees.
• Angle of rotation - parameter characterizing the ability to rotate the blades horizontally. It lies within 90-360 degrees. Many modern models are equipped with auto-rotation, that is, the engine with blades moves along a horizontal axis, thereby cooling the room.
• Noise level - the smaller this parameter, the more comfortable the home fan functions. Floor standing units must operate with low noise levels (no more than 30 decibels). When buying a structure, you need to check its noiselessness. Quiet fans are usually much higher.
• Blowing mode affects the air exchange rate. The number of rotation speeds is in the range of 2-8.

• Control system can be touch or push-button. The presence of the display allows you to visually control the mode and connected functions of the device.
• Remote control capability allows remote control of the fan's functionality, which greatly simplifies the process of its operation.
• Timer provides automatic shutdown of the fan if necessary.
• Ionizer - an important function due to which the air receives negatively charged particles, which have a beneficial effect on the general condition of a person.
• Humidifier - a function by which the optimal level of humidity in the room is maintained. Fans with this feature cost a little more than usual.
• Availability of a certificate must be checked upon purchase, since only then can the quality and compliance of the device be verified.
• Manufacturers . It is necessary to find such a device so that its cost and quality are justified. For many decades, branded equipment has won a reputation of buyers, which in most cases guarantees high-quality devices and their durability.

The disadvantage is that the materials of manufacture are not of the highest quality.

Major malfunctions

The fan may experience the following malfunctions.

• The fan does not turn on, but the light is on . The cause may be a malfunction of the control unit. To eliminate this breakdown, it is necessary to disassemble the unit. The fan should not be connected to the mains at this time. You won't be able to fix a broken button, so you'll have to replace it.
• The fan does not work and the lamp does not light up . First you need to check the presence of voltage. To do this, it is enough to connect any electrical device to the network. If the device works, then the problem is with the plug or cord.

To check the serviceability, it is necessary to disassemble and check the connection of the wires to the terminals. To check the cord, you need to dial with a tester. Replace the cable if necessary.

• The blades of the device do not rotate well . In this case, it is necessary to disassemble the case. The problem may be a lack of lubrication in the bearings.
• The device does not rotate sideways. The malfunction appears when the screws of the crank mechanism are loosened. In this case, you should disassemble the housing with the motor, you can also check the serviceability of the switch.
• The device makes a strange noise and does not spin . There may be several reasons for this: there is no lubricating oil on the bearings; malfunction of the capacitor or motor.

DIY repair

If the floor fan breaks down, you should study its operation diagram, after which you can repair the device yourself. When repairing a malfunction of the fan motor, it is necessary to lubricate the parts. Most often, after this procedure, the device begins to work properly. Machine oil can be used as a lubricant.

Stator windings often break in device motors . To check for a break, it is necessary to sharply twist the blades to the right. If after that the fan started working, then one of the windings really broke. To determine a specific section of the cliff, you should make a call with a multimeter according to the instructions. In the event of a stator break, assembling or repairing the winding will cost much more than buying a new fan.

To increase the service life, it is recommended to periodically clean the fan motor from dust and lubricate the working parts. The procedure for disconnecting the wires and the subsequent connection should be very carefully carried out. In no case should they be confused with each other.
