Probe to the distance between bottom of lubricating cup 100, be used as initial distance.In range hood 10 in use, range sensor 202
Measure, just send the distance of the probe and pasta in the lubricating cup 100 of the range sensor 202 of detection to control every time
Device 201.
Controller 201 subtracts initial distance by the distance popped one's head in pasta in the lubricating cup 100, can obtain oil level in light
The change distance, delta H in road direction.The angle [alpha] of light path can be previously obtained, such as produce 10 machine of range hood when, by set away from
Relative position from sensor 202, speculum 206 and lubricating cup 100 is calculated.By Δ H*cos α, the height of oil level can be calculated
Degree.When installing speculum 206 and range sensor 202, it is necessary to which the bottom of lubricating cup 100 can be irradiated to by meeting light.
It is arranged on using by range sensor 202 and speculum 206 by the way of two side walls of shell, lubricating cup can be avoided
100 tops are in vacant state, the problem of being difficult mounting distance sensor 202.
3rd embodiment
Fig. 5 is refer to, is the flow chart for the oil level detection method that third embodiment of the invention is provided.The oil level detection side
Method includes：
Step S101, measures the lubricating cup 100 in empty cup stage, the bottom of range sensor 202 and the lubricating cup 100
Distance.
Range sensor 202 is when the first time of range hood 10 uses and lubricating cup 100 is empty cup (oil-free in lubricating cup), measurement
The distance between the probe of range sensor 202 and the bottom of lubricating cup 100, are stored in as initial distance, and by this initial distance
The memory 203.
Step S102, in predetermined time, the distance of measurement distance sensor 202 and pasta in the lubricating cup 100.In oil suction
Cigarette machine 10 is in use, range sensor 202 measures (every 30 minutes after as started shooting) every time, just by the range sensor of detection
The distance of 202 probe and pasta in the lubricating cup 100 is sent to controller 201.
Step S103, according to the distance between the range sensor 202 and pasta, calculates the oil in the lubricating cup 100
Position height.
If the vertical lubricating cup 100 of probe is measured, controller 201 subtracts the distance between the probe of reception and pasta
Initial distance is removed, level height is just obtained；If probe has certain angle, it is necessary to by distance difference and the sine value of angle with pasta
Or cosine value is multiplied, and obtains level height.
If specifically, when probe is that vertical lubricating cup 100 is measured, the oil can be calculated by formula Δ H=H-Hn
Position height；Wherein, Δ H is the level height, and H is the range sensor 202 and institute when the lubricating cup 100 is in empty cup
State the distance of pasta in lubricating cup 100, Hn be in predetermined time, the range sensor 202 with the lubricating cup 100 pasta away from
From.
Step S104, level height is less than preset height
If the level height is less than the alarm height, remeasure；If the level height is more than or equal to institute
Alarm height is stated, then performs step S105.
Specifically, oil level ratio can be calculated by formula a=Δs H/d, the oil level ratio is opposed with preset ratio
Than if oil level ratio is more than or equal to the preset ratio, alarm signal is sent to the communication module 204；Wherein, a is
Oily height in the lubricating cup 100 and the ratio between the depth of the lubricating cup 100, d are the depth of lubricating cup 100.
Step S105, sends alarm signal.Controller 201 sends alarm signal to alarm 205 and communication module 204,
Oil level in prompting user lubricating cup 100 has reached preset height.
In summary, oil level detection method provided in an embodiment of the present invention, device and range hood 10, using Distance-sensing
Device is detected in real time to level height, with reference to the different mounting means of range sensor, be range hood it is more attractive in appearance and knot
Structure is simple, easy for installation.Mobile phone is sent the data to by communication module, oil level situation in user's lubricating cup is more intuitively told,
Oil level information can also be remotely pushed, user's carry out cleaning lubricating cup is reminded.
