Smoke Exhaust/Range Hood, is an electrical appliance such as the oil fume produced by the family kitchen for absorbing and cooking. It should not only complete the functional role, but also have the concept of decorative concepts that integrate the modern kitchen pattern.After the development of the range hood, the range hood is no longer limited to the simple tools of the kitchen to remove oil fume, but increase the entertainment range hood that adds more entertainment and use functions.The hoods of the security system are installed with network -controlled network range hoods.The range hood needs to be cleaned regularly. Simply cleaning is not to deal with oil pollution. The cleaning range hood must be cleaned using a professional cleaning agent.
What are the types of hood
The range hood can be divided into two European and Chinese categories.European hoods are mainly wall -mounted, as well as some Chinese -style high -end products; Chinese hoods are mainly wall -mounted, with dark cover and shallow cover.The number of motors and wind wheels can be divided into: dual -machine and stand -alone (that is, dual and single tube).From the accumulation of dotted oil, it can be divided into Shuangyou Road and Sanyou Road (gas room, protective cover oil and wind transportation oil).The structure of the cigarette room is divided into single -layer (three oil roads), double -layer inner dan type (dual oil road), multi -layer network (multi -oil road), etc.From the functional structure, it can be divided into multimedia hood, embedded hood, wall suction, side suction hood, solid wood hood, etc.
Sideline
The new appearance design, its advantages are closer to the cooker panel, located in the golden smoke control area, better matching with the cabinet; straight -absorbing structure, tempered glass decoration; original zero oil fume technology; easy disassembly oil net, free tool disassembly; independent intelligence; independent intelligence; independent intelligenceInduction switch, easy to disassemble, convenient maintenance; low energy -consuming and environmentally friendly motors, strong power and other advantages.
European -style machine (top)
Advantages: Big brands are more fine.Services are also guaranteed.Strong suction.The smoking effect is good.Disadvantages: Large volume, not suitable for small -scale kitchens.
Lower row
Advantages: The overall one -machine purchase is complete, saving space, the oil fume does not pass by the face, and the oil fume has a high rate of absorption.Disadvantages: There is a phenomenon of pulling fire on the stove, the heat efficiency of the cooker decreases;
How to repair the hood failure
Fault one: You cannot start after power -on
Cause analysis and processing: The power line is disconnected or the joint is off -welded, and the circuit breaking point or off the welded joints are carefully detected to re -weld it;To change the new product; the motor startup capacitor capacity is reduced or short -circuit and disconnect. This must be replaced with capacitors of the same specifications to run the motor; the transmission coil is broken or short -circuit, and the transmission coil is repaired or replaced.Bearing; Short -circuit or connecting line disconnection of stator winding, repairs or replace the stator winding or replace new products.
Fault 2: There are abnormal sounds or noise during operation
Cause analysis and treatment: Improper assembly causes the wind leaves to loosen and touch the wind guidance frame to produce abnormal sounds, re -assemble and tighten the wind leaf tight nails; the motor bearing is severely worn, and the same type of bearing must be replaced.The gap makes it uniform. If the axial direction is moving, appropriate pads should be added; the wind leaves are unbalanced, corrected the wind leaves, and the wind and quiet balance of the wind leaves; the design of the wind pipeline is unreasonable.The wind pipeline should be as small as possible, and the curved at the turning point should be large and round.
Fault 3: The range hood vibration is too large
Cause analysis and treatment: fixed or not, poor installation, add rubber pads or foam plastic, fixed and strong; there are foreign bodies on the leaves, and the internal dirt is too thick. Clear foreign objects and internal dirt on the leaves;, Re -adjusted the spindle and wind leaf set simplifying its concentric; motor bearings or bearing holes are too large, replacing new bearing of the same specifications; local short -circuit or disconnection of the motor winding, replace the winding or motor.
Fault 4: Oil leakage
Cause analysis and treatment: Improper installation, insufficient elevation angle, reinstalling, keeping it a certain elevation angle, so that the suction oil naturally flows down the oil cup;It cannot be dripped under the role of tension; the sealing strip has been invalidated for a long time, adding rubber or foam plastic strip at the seal to tighten the parts and improve the level of sealing;Net and pipelines to avoid smoke and oil overflow.
Fault 5: Poor fuel smoke effect poor effect
Cause analysis and treatment: The installation point is too high to leave the stove, and the installation point is appropriately reduced; the exhaust pipe is too long or the direction of the air outlet is not properly selected, the exhaust pipe is appropriately shortened, and the direction of the air outlet is re -selected;Seal it strictly; internal circulating activated carbon failure, replacement of active carbon; indoor and outdoor pressure differences, properly open the door, window to reduce indoor and outdoor pressure differences; if the voltage is too low, configure the regulator if necessary;Cover the oil and clean the oil.
Failure six; piano key switch fails
Cause analysis and processing: If you press the piano key switch to lock, you cannot start the motor by pressing each gear.It is indicated that only the discharge of the contact of the file or the connection of the stall is broken, and the connection and connection should be repaired; if you press the piano key to switch the motor to run, the piano keys cannot be locked, mainly because the conductive spring deformation and conductive in the switch are switched.If the film cannot be touched, or the switching reservoir displacement or fall off, the spring sheet should be adjusted or replaced with a new switch;Essence
Failure 7: The range hood affects cooking fire source heat
Reasons and analysis and processing: The selection of exhaust volume is too large, causing waste of heat, extending the heating time, and the discharge volume should be selected appropriately; the range hood is too low to increase the height of the range hood.
Fault Eight: Polymump Highlights are seriously dirty
Cause analysis and processing: Do not clean up the range hood in time, and should be cleaned in time to test the range hood; if the airway is not cleaned, you can turn on the cover, remove the cover, remove each board and filter, and clean it after cleaning.
Failure Nine: Touch Switch is not spiritual
Cause analysis and processing: Replace the button/control vector board
