Embodiment
This embodiment provides a kind of water level inductor, the problem of its water level induction mistake that water level inductor of the prior art can be avoided easily to occur.This embodiment additionally provides a kind of electrical equipment comprising above-mentioned water level inductor.
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 1-Fig. 3, the water level inductor that this embodiment provides, comprise pedestal 11, beam emissions parts 12, mirror body 13 and light beam induction installation 14.When water level does not rise to the reflecting surface of mirror body 13, the light beam that beam emissions parts 12 send irradiates the reflecting surface on mirror body 13 after air dielectric, light beam enters air dielectric after the reflex of reflecting surface, and the position residing for light beam induction installation 14 can receive the light beam launched through reflecting surface.
Should be appreciated that light beam is after the reflection of water and refraction, can there is skew or weaken in the light beam reflected from water.Therefore, when water level is increased to the reflecting surface of mirror body 13, first the light beam that beam emissions parts 12 send arrives the reflecting surface in water after the reflection of water and refraction, light beam after the reflex of reflecting surface by penetrating in air dielectric in water, now, the light beam of injection owing to there occurs refraction and reflection in water, and light beam can depart from former route or intensity can weaken, now, light beam induction installation 14 senses that light changes and corresponding generation electric signal.
Setting like this, the water level sensor that this embodiment provides, relative to buoy liquid level induction system, it is without friction, mechanical moving element, and therefore, reliability is higher; And cost is low, volume is little, effectively improve water tank utilization factor; Adopt the photoelectric level cost that opens the light lower than float type, can water tank volume be improved; And detecting accurately high, fast response time, level control (LC) is more accurate.
In a kind of embodiment of the present utility model, the light beam that beam emissions parts 12 send, the reflecting surface primary event caning be passed through mirror body 13 can reflex to light beam induction installation 14.Namely, in air ambient, the light beam that beam emissions parts 12 send directly reflexes to light beam induction installation 14 after the first reflecting surface 15 of mirror body 13 reflects.After the first reflecting surface 15 is submerged in water, the light beam that beam emissions parts 12 send reflects when air enters in water, light beam irradiation to the first reflecting surface 15 of refraction reflects, the light beam of reflection is by penetrating in air in water, now, the light beam reflected can offset relative to the light beam reflected in air ambient, and then can not be sensed by light beam induction installation 14, and then light beam induction installation 14 can by the change of refraction of optical beam skew induction water level.
In the another kind of embodiment that the utility model provides, in air ambient, when namely the reflecting surface of mirror body 13 does not enter in water, the light beam that beam emissions parts 12 send through multiple reflections, then can be received by light beam induction installation 14.Such as, mirror body 13 can comprise the first reflecting surface 15 and the second reflecting surface 16, first reflecting surface 15 and the second reflecting surface 16 are arranged in angle, the light beam that beam emissions parts 12 send through air exposure in the first reflecting surface 15, irradiate after the reflex of the first reflecting surface 15 in the second reflecting surface 16 and after the reflex of the second reflecting surface 16, enter air and can be received by light beam induction installation 14.Setting like this, when the reflecting surface of mirror body 13 does not enter in water, the light beam that beam emissions parts 12 send is through two secondary reflections, can be received by light beam induction installation 14, after any one reflecting surface of mirror body 13 enters in water, the intensity of the light beam reflected can weaken or can offset, and then the light signal that light beam induction installation 14 receives can change.
In the preferred version of this embodiment, as depicted in figs. 1 and 2, first reflecting surface 15 and the second reflecting surface 16 angle are 90 °, the light beam that beam emissions parts 12 send is 45 ° through air exposure in the incident angle of the first reflecting surface 15, light beam is 45 ° through air exposure in the incident angle of the second reflecting surface 16 after the first reflecting surface 15 reflects, and light beam enters air and can be received by light beam induction installation 14 after the reflection of the second reflecting surface 16.
When water level sensor is installed, beam orthogonal can be made to irradiate in the water surface, so arrange, the reflecting surface of mirror body 13 is after entering in water, because beam orthogonal irradiates water entering surface, and light beam is also that vertical sand shooting goes out the water surface after the first reflecting surface 15 and the reflection of the second reflecting surface 16, can not reflect.But light beam is after water transmission, and the intensity of light beam can be decayed, and then the light signal strength that light beam induction installation 14 senses also can change.
In addition, in this embodiment, beam emissions parts 12 are preferably generating laser, and the beam focus sent due to generating laser is more concentrated, and the beam intensity degree of accuracy that light beam induction installation 14 senses is higher.
This embodiment additionally provides a kind of electrical equipment, comprises water tank and the water level inductor for responding to water level in water tank, and described water level inductor is water level inductor as above.This electrical equipment can be the electric equipment products that washing machine, dehumidifier or water purifier etc. have water level inductor.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
