Description
Technical field
The utility model relates to household appliance technical field, refers to especially a kind of range hood.
Background technology
At present, the range hood on market does not have illumination functions mostly, when cooking night, because the not good problem of illumination usually causes the generation that misplaces the problems such as condiments.Based on this, someone proposes a kind of range hood with illumination functions, has solved to a certain extent lighting problem.But still there is following problem in this mode: need staff to control the control panel on range hood, illuminating lamp just can carry out work.
And when culinary art, staff can be infected with various food materials, can cause unnecessary hygienic issues with hand control panel.Based on this, be necessary to propose a kind of range hood, address the above problem.
Utility model content
The utility model proposes a kind of range hood, solved the problem that in prior art, illumination needs staff to control to range hood.
The technical solution of the utility model is achieved in that
A kind of range hood, comprise: shell and be installed on the exhausting system in described shell, described shell is provided with the opening for air inlet, described opening part is fixedly connected with face glass, described opening part is also fixedly connected with Inlet Network, and described Inlet Network is located at described face glass one side, and described opening part is provided with lighting, described shell inner side is provided with human body sensing assembly, and described human body sensing assembly is electrically connected to described lighting by controller.
Further, described lighting comprises at least one group of light fixture, and described light fixture comprises substrate and is located at the LED lamp pearl group on described substrate.
Further, described light fixture is embedded in described face glass.
Further, described human body sensing assembly comprises rounded Fresnel optical filter and the pyroelectric sensor being connected with described Fresnel optical filter.
Further, described controller comprises: signal processing module and the delay switch module being electrically connected to described signal processing module, and described signal processing module is electrically connected to described human body sensing assembly, and described delay switch module is electrically connected to described lighting.
The beneficial effects of the utility model are: pass through such scheme, human body sensing assembly is located on range hood, and be electrically connected to lighting, utilize human body sensing assembly induction physical activity, thereby startup lighting, without staff control panel, can realize the control to lighting, facilitate operation, thereby and staff without touching, make cooking process health, clean.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the perspective view of an embodiment of a kind of range hood of the utility model;
Fig. 2 is the circuit principle structure schematic diagram of range hood shown in Fig. 1.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
An embodiment referring to a kind of range hood of the utility model shown in Fig. 1 and Fig. 2, comprise: shell 1 and the exhausting system 2 that is installed on described shell interior 1, described shell 1 is provided with the opening 11 for air inlet, described opening 11 places are fixedly connected with face glass 3 and Inlet Network 7, Inlet Network 7 is located at face glass 3 one sides, and Inlet Network 7 can play a role in filtering.Described opening 11 places are provided with lighting 5, and described shell 1 inner side is provided with human body sensing assembly 4, and described human body sensing assembly 4 is electrically connected to described lighting 5 by controller 6.
Described lighting 5 comprises at least one group of light fixture, and described light fixture is embedded in described face glass 3.Described light fixture comprises substrate and is located at the LED lamp pearl group on described substrate.LED has the free of contamination feature of green light source, has been widely used in the lighting fields such as street lamp.Now LED is arranged on range hood, intensity of illumination is high, and power consumption is few.The light fixture being embedded in face glass 3 can prevent oil pollution.
Described human body sensing assembly 4 comprises rounded Fresnel optical filter (diagram does not provide) and the pyroelectric sensor 41 being connected with described Fresnel optical filter.Fresnel optical filter has the infrared ray that human body can be sent to be assembled, and makes pyroelectric sensor can judge whether more accurately that someone exists.
Described controller 6 comprises: signal processing module 61 and the delay switch module 62 being electrically connected to described signal processing module 61, and described signal processing module 61 is electrically connected to described pyroelectric sensing device 41, and described delay switch module 62 is electrically connected to described lighting 5.
In working order, when human body is during near range hood, pyroelectric sensor 41 senses human body infrared by Fresnel optical filter, and send electric signal transmission to signal processing module 61, signal processing module 61 receives after signals Signal coding, and send instruction to delay switch module 62, thereby delay switch module 62 is opened described lighting 5 and is realized illumination functions.And delay switch module 62 has Preset Time, after lighting 5 is opened, the arrival scheduled time closes lighting 5, plays energy saving effect.If now human body does not leave range hood yet, human body sensing assembly 41 still can send to controller 6 signals, thereby maintains lighting 5 openings.
Pass through such scheme, human body sensing assembly 4 is located on range hood, and be electrically connected to lighting 5, utilize human body sensing assembly 4 induction physical activities, thereby start lighting 5, without staff control panel, can realize the control to lighting 5, facilitate operation, thereby and staff without touching, make cooking process health, clean.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
