Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model embodiment；
Fig. 2 is the complete machine workflow schematic diagram of the range hood of the utility model embodiment；
Fig. 3 is the workflow schematic diagram of the self-cleaning function of the range hood of the utility model embodiment.
Specific implementation mode
The utility model is described in further detail below in conjunction with attached drawing embodiment.
As shown in Figure 1, the automatically cleaning range hood in the present embodiment includes casing 1, wind turbine 2 and spray equipment, wind turbine 2
Set on 1 inside of casing and centrifugal blower is used, wind turbine 2 includes spiral case 21 and the impeller 22 inside spiral case.Spray equipment
It can be to 22 surface water spray of 21 inner wall of spiral case and impeller, to form hydrophilic coating in 21 inner wall of spiral case and 22 surface of impeller.
In the present embodiment, spray equipment specifically includes solenoid valve 3, atomising device 4 and nozzle 5, and the water inlet end of atomising device 4 passes through electromagnetism
Valve 3 is connected with external water inlet, and the water outlet of atomising device 4 is connected with nozzle 5, and nozzle 5 stretches to inside spiral case 21.
In range hood operational process, lipophilic feature is more than by the hydrophily of hydrophilic coating, spray equipment is controlled by program
Work uninterruptedly carries out moisture film covering to spiral case inside and impeller surface, and the oil smoke in range hood operational process is isolated in water
Outside film, to have the function that oil smoke is isolated, the effect of oily dirt free (automatically cleaning) is reached.
In addition, being equipped with automatically cleaning tip button (not shown) on the control panel of the range hood.Wind turbine 2 is accumulative to be used
Time reaches setting value such as 20 hours or when accumulative access times reach setting number such as 60 times, and automatically cleaning tip button, which is in, to be flickered
State carries out concentration reprocessing, to reach more to remind user to use self-cleaning function to the part greasy dirt of wind turbine inner cavity covering
The purpose for thoroughly removing greasy dirt, during 2 automatically cleaning of wind turbine, automatically cleaning tip button is in and is always on state.If in addition, control plane
Plate does not prompt automatically cleaning, if user identifies oneself to need to carry out automatically cleaning, can with long-press automatically cleaning tip button, key flash, then
By once can then executing self-cleaning function.
The control method of the automatically cleaning range hood normal workflow, includes the following steps：
1., start wind turbine and start spray equipment simultaneously, spray equipment continuous working period is T1, and T1=1~2min；
2., in fan operation engineering, if the fan operation time is more than setting time T2, T2=3~5min, then after the T2 times
It is again started up spray equipment, and makes spray equipment continuous working period T3, T3=1~3min；It is set if the fan operation time is less than
Fix time T2, then wind turbine is out of service, and spray equipment does not start；
If 3., fan operation terminate before start-up study function, wind turbine continues to run with time T4, T4=2~4min, and sprays
Shower device is again started up and continues spray time T5, also, T5 ﹤ T4, if not actuated delay function, complete machine are out of service.
Above-mentioned steps 1. in, high rotating speed is not reached due to rotation speed of fan at this time and bottom oil smoke does not reach wind turbine at this time
Place, water spray effect at this time is intended to make to adhere to water membrane on impeller and spiral case wall before oil smoke arrival blower fan system, in oil smoke
Play the role of that oil smoke is isolated when rising to blower fan system.
Above-mentioned steps 2. in, it is that wind turbine surface of internal cavity is made persistently to adhere to moisture film to be again started up spray equipment, this is is circulated throughout
Journey, preferred cycle number are 2~5 times.In addition, user's operation stops key, this means that wind turbine is out of service, and spray equipment
Do not start.
Above-mentioned steps 3. in, be arranged T5 ﹤ T4, be in order to allow spray into blower interior water can smoothly be discharged outside range hood.
The control method of the automatically cleaning range hood under automatically cleaning pattern, includes the following steps：
1., user touches or presses automatically cleaning tip button；
2., spray equipment bring into operation, it is T6, and T6=1~2min that wind turbine, which operates the time,；
3., spray equipment and wind turbine stop, and dwell time is T7, and T7=3~5min；
4. while start spray equipment and wind turbine, and the duration is T8, and T8=3~5min.
Wherein, under automatically cleaning pattern, step 2. with step 3. cyclic process be 3~5 times, step 2. in wind turbine be in
Low-speed running state, the wind turbine of step 4. are to run at high speed and counter-rotated condition.
