Abstract
The utility model relates to a pollution degree detection device is used in kitchen, its characterized in that: the light source and the optical signal receiver that contain relative setting to and differentiate the unit with the dustiness that optical signal receiver is connected. Compared with the prior art, the utility model has the advantages of: set up light source and optical signal receiver, then set up light permeable member in the light path between light source and optical signal receiver, thus the rethread dustiness differentiate the unit and carry out the pollution degree that optical signal receiver is differentiated in the comparison to the signal that optical signal receiver received, this structure can be differentiated by the degree of pollution to the kitchen with the device, simple structure, the easy realization.
Description
Technical field
This utility model is related to a kind of kitchen pollution level detection means.
Background technology
With intelligent development, optical pickocff is more and more in household appliance technical field application, and photoelectric sensor is to adopt
Photoelectric cell is as the sensor of detecting element.It includes detection light emitting devices and detection optical pickup apparatus, detection
Light emitting devices launch detection light, and detection optical pickup apparatus receive detection light, and the detection light of reception is through substances to be measured (such as oil
Smoke density) refraction after, light intensity can change, then relend help photoelectric cell further by light intensity signal change
Become the signal of telecommunication.Photoelectric detecting method has the advantages that high precision, reaction be fast, noncontact, and can survey that parameter is many, the knot of sensor
Structure is simple, and flexible form is various, and therefore, electro-optical pickoff is applied widely in detection and control.
Under specific application scenarios, photoelectric sensor may face device to be led under sensitivity by dust or oil pollution
The risk that fall even lost efficacy, therefore, by detecting the contaminated degree of optical pickocff so that prompting maintenance is for sensor
Popularization and application play an important role.
In addition, also having other a lot of kitchen devices, such as: the transparent face mask of lampblack absorber, the transparent panel of kitchen range, it is arranged on kitchen
Various sensor temperature sensors in room, humidity sensor, gas concentration sensor, special due to its applied environment
Property, can be often in oil smoke compact district, these devices are in the course of the work it is most likely that be subject to dust or oil pollution thus leading
Cause sensitivity to decline even to lose efficacy, therefore exploitation kitchen device contamination degree detection device has realistic meaning, prior art very much
In, then do not have this kind of technology and product to come out.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of kitchen pollution level inspection for above-mentioned prior art
Survey device, the contaminated degree of kitchen device can be detected.
The technical scheme that this utility model solution above-mentioned technical problem is adopted is: a kind of kitchen pollution level detection dress
Put it is characterised in that: comprise light source and the optical signal receiver being oppositely arranged, and the dustiness being connected with optical signal receiver
Judgement unit.
As improvement, described dustiness judgement unit comprises subtractor and the display unit being connected with subtractor, this subtraction
Device is used for optical signal receiver measures and preserves after light source is opened when being clean by initial optical signal receiver signal value m1 with
The signal value m2 that after optical signal receiver is contaminated, light source unlatching optical signal receiver measures is subtracted each other, by the difference of m1 and m2
Value judges whether light transparent member is contaminated, and difference bigger explanation pollution level is bigger, and is shown by display unit.
Improve again, the kitchen pollution level detection means that this utility model provides also includes being arranged on and also includes blocking in light
Light transparent member in front of signal receiver.
Described light transparent member is the light transparent member in lens or glass or kitchen appliance product.
Described light source and optical signal receiver can be respectively adopted detection Optical Transmit Unit and detection in oil smoke sensor
Light receiving unit.
Compared with prior art, the utility model has the advantage of: setting light source and optical signal receiver, then by pollution
The signal that degree judgement unit receives to optical signal receiver is compared thus differentiating the pollution level of optical signal receiver, this knot
Structure contaminated degree can differentiate to kitchen device, and structure is simple, easily realizes.
Brief description
Fig. 1 is kitchen pollution level structure of the detecting device schematic diagram in this utility model embodiment one.
Fig. 2 is kitchen pollution level structure of the detecting device schematic diagram in this utility model embodiment one.
Specific embodiment
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
Embodiment one
Kitchen pollution level detection means as shown in Figure 1, it comprises the light source 1 being oppositely arranged and optical signal receiver 2,
And the dustiness judgement unit 4 being connected with optical signal receiver, described dustiness judgement unit 4 comprises subtractor and and subtraction
The display unit that device connects, after preserving light source unlatching when optical signal receiver is clean in subtractor, optical signal receiver measures
Signal value m1;The signal value that light source unlatching optical signal receptor measures after optical signal receiver is contaminated is m2, subtraction
By the difference of m1 and m2, device judges whether optical signal receiver is contaminated, difference bigger explanation pollution level is bigger, and leads to
Cross display unit to be shown.
Embodiment two
From unlike embodiment one, also include blocking the light transparent member 3 in front of optical signal receiver.Due to transmittance section
Part 3 blocks in front of optical signal receiver, and such greasy dirt will not pollute to optical signal receiver, but can be to light transparent member
3 pollute, and this structure is by the pollution level indirectly to judge optical signal receiver to the pollution level of light transparent member 3.
In actual application environment, light transparent member can be lens or glass or kitchen to above-mentioned kitchen pollution level detection means
Light transparent member in electric product.And light source and optical signal receiver then can be respectively adopted the detection light transmitting in oil smoke sensor
Unit and detection light receiving unit.
Claims (5)
1. a kind of kitchen pollution level detection means it is characterised in that: comprise light source and the optical signal receiver being oppositely arranged, with
And the dustiness judgement unit being connected with optical signal receiver.
2. kitchen pollution level detection means according to claim 1 it is characterised in that: described dustiness judgement unit bag
The display unit be connected containing subtractor and with subtractor.
