Abstract
The utility model discloses a range hood capable of quickly emptying oil smoke in a smoke chamber, which comprises a shell, a control panel and a blower. The range hood also comprises a ventilating fan, wherein the ventilating fan is arranged at an interface between an air duct of a range hood and an external smoke flue, and the interface is also provided with a check valve; and the ventilating fan and the check valve are connected with the control panel through control lines. According to the utility model, the retention time of oil smoke in the air duct and a smoke chamber is reduced; the corrosion of the oil smoke to the air duct and the smoke chamber is reduced; and odor tainting in the smoke flue, dust invasion and back flow of cold air in winter are also avoided.
Description
Technical field
The utility model relates to smoke exhaust ventilator, relate in particular to a kind of can fast evacuation smoke chamber in the smoke exhaust ventilator of oil smoke.
Background technology
Smoke exhaust ventilator claims again range hood, is a kind of kitchen appliance that purifies kitchen environment.It is arranged on kitchen gas cooker top, the harmful oil smoke producing can be taken away rapidly in the refuse of cooking stove burning and cooking process, outside discharge chamber, reduces and pollutes, and purifies air, and has gas defence, explosion-proof safety guarantee effect.Early stage family kitchen smoke evacuation work is all completed by ventilating fan.Although ventilating fan can exclude the most of oil smoke in kitchen, the pollution of the oil smoke that it produces in unable solution culinary art to whole kitchen, and the oil smoke of ventilating fan discharge is owing to acting directly on external wall of house, and very large to the appearance effects of building.The oil smoke producing in culinary art contains a lot of harmful materials, if people works for a long time in the room that is full of oil smoke, can cause the generation of a lot of diseases.So smoke exhaust ventilator has become the requisite cooking apparatus of Modern Family.
But in prior art, the air draft poor effect of smoke exhaust ventilator, still has oil smoke in pipeline after shutdown, then when next time start, also to first get rid of original residual oil smoke.
Utility model content
The technical problems to be solved in the utility model is in the air channel for smoke exhaust ventilator in prior art, to also have residual oil smoke, and the defect of the easy taint of odour of oil smoke in flue, provide a kind of can fast evacuation smoke chamber in the smoke exhaust ventilator of oil smoke.
The utility model solves the technical scheme that its technical problem adopts:
Provide a kind of can fast evacuation smoke chamber in the smoke exhaust ventilator of oil smoke, comprise casing, control panel and blower fan, this smoke exhaust ventilator also comprises ventilating fan, and this ventilating fan is arranged at the interface between air channel and the extraneous flue of smoke exhaust ventilator, is also provided with check-valves at this interface; This ventilating fan, this check-valves are all connected with control panel by control line.
In smoke exhaust ventilator described in the utility model, described control line is placed in air channel.
In smoke exhaust ventilator described in the utility model, the bottom of casing is provided with lighting device, and lighting device comprises LED lamp and removable transparent glass sheet guard shield.
In smoke exhaust ventilator described in the utility model, be also provided with cover of upholstery in casing outside, between casing and cover of upholstery, be radian and connect.
The beneficial effect that the utility model produces is: the utility model is installed ventilating fan, check-valves at wind passage mouth and flue junction, automatically open when the smoke exhaust ventilator exhaust by ventilating fan, the gas of fast evacuation smoke chamber, automatically closed after while stopping exhaust, ventilating fan postpones a period of time, close exhaust passage.Reduced the time of staying of oil smoke at air channel and smoke chamber, reduced the corrosion of oil smoke to air channel and smoke chamber, closing after check-valves work also avoided the taint of odour, dust of flue to invade and the pouring in down a chimney of cold air in winter.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 be the utility model embodiment can fast evacuation smoke chamber in the structural representation of smoke exhaust ventilator of oil smoke.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, of the present utility model can fast evacuation smoke chamber in the smoke exhaust ventilator of oil smoke, comprise casing 1, control panel 8, blower fan, ventilating fan 4 and check-valves 3.This ventilating fan 4 is arranged at the interface between air channel 9 and the extraneous flue 2 of smoke exhaust ventilator, is provided with check-valves 3 at this interface; This ventilating fan 4, this check-valves 3 are all connected with control panel 8 by control line 5.In embodiment of the present utility model, the control line 5 of ventilating fan and check-valves is arranged in air channel 9, and control line 5 connects check-valves 3, ventilating fan 4 and control panel 8.
This smoke exhaust ventilator is also provided with lighting device 6 and collection discharge equipment 7.Casing 1 bottom center has pump orifice, and collection discharge equipment 7 is arranged on the pump orifice of casing 1.Lighting device 6 is arranged on bottom of shell front side, is made up of not only energy-conservation but also safety in ensureing illumination LED lamp and the removable transparent glass sheet guard shield of outer cover.
When the work of this smoke exhaust ventilator, control panel 8 is controlled check-valves 3 and is first opened, and ventilating fan 4 subsequent workings make the interior formation negative pressure in air channel 9, and after certain hour, the blower fan of (as half a minute) smoke exhaust ventilator is started working, the gas in can fast evacuation smoke chamber.In the time that smoke pumping quits work, press the gauge tap of control panel 8, blower fan quits work, but ventilating fan 4 can postpone quit work after a period of time (as three points of kinds), wait ventilating fan 4 to quit work after check-valves 3 automatically closed, close exhaust passage.This has just reduced the concentration of oil smoke at air channel and smoke chamber, has reduced the corrosion of oil smoke to air channel and smoke chamber, and the automatic closure of check-valves 3 has also been avoided pouring in down a chimney of dust intrusion and cold air in winter.
For easy to operate, control panel 8 is contact panel, can avoid the erosion of oil smoke counter plate.
In the utility model, be also provided with cover of upholstery 10 in casing 1 outside in addition, between casing 1 and cover of upholstery 10, be radian and connect, to avoid occurring dead angle inconvenience cleaning.
To sum up, the utility model is installed ventilating fan, check-valves at the wind passage mouth of smoke exhaust ventilator and flue junction, automatically opens the gas in fast evacuation smoke chamber by ventilating fan when the smoke exhaust ventilator exhaust, automatically closed after while stopping exhaust, ventilating fan postpones a period of time, close exhaust passage.Reduced the time of staying of oil smoke at air channel and smoke chamber, reduced the corrosion of oil smoke to air channel and smoke chamber, closing after check-valves work also avoided pouring in down a chimney of dust intrusion and cold air in winter.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
