Description
[technical field]
The utility model relates to a kind of close-suction range hood of smoke collecting chamber air inlet automatic open close, belongs to smoke elimination technique field.
[background technology]
Known range hood is provided with air intake web plate at smoke collecting chamber air inlet, and because range hood does not seal air inlet outside air intake web plate when the holding state, the peculiar smell of range hood inside easily comes out, and affects kitchen air quality.In recent years, occurred on the market utilizing motor to drive into a kind of like this range hood of air port vane group, the concrete structure of this range hood is: in air inlet two side, be arranged with some to axis hole be longitudinally arranged in some blades of air inlet, at each blade top margin, be provided with a longer rotating shaft that can drive this blade rotation, one end of all rotating shafts is loaded in air inlet one sidewall axis hole, all stretch out after the axis hole of smoke collecting chamber opposing sidewalls their opposite end, an and hinged connecting lever separately, the other end of these connecting levers is all hinged on a pull bar, the far-end of pull bar is connected with motor output shaft by a connecting rod, under motor drives, driving vane group to rotate opens wide air inlet, after motor stalling, vane group is sagging with sealing air inlet under the drive in each rotating shaft from weight by it, therefore range hood is when holding state, in machine, peculiar smell can not come out.Adopt this frame for movement to seem complicated, and because longer rotating shaft is to be arranged at blade top margin, while opening vane group, need to overcome every blade from weight, power consumption cost is high.
[utility model content]
The purpose of this utility model is to provide the close-suction range hood that a kind of air inlet is renovated the smoke collecting chamber air inlet automatic open close that plate overturns light and handy; this close-suction range hood can prevent that when stopped status peculiar smell is dispersed into kitchen space in smoke collecting chamber, has avoided kitchen to suffer air pollution.
For this reason, the utility model provides following technical scheme:
A kind of close-suction range hood of smoke collecting chamber air inlet automatic open close, comprise smoke collecting chamber, the separated web plate of oil smoke, bellows, air outlet assembly and oil trap, smoke collecting chamber communicates with bellows by being located at the separated web plate of oil smoke at its top, air outlet assembly is located at the top mouth of bellows, oil trap is arranged at smoke collecting chamber bottom, described smoke collecting chamber is disposed with control panel from top to bottom in its front, air inlet is renovated plate and cover plate, air inlet is renovated near the hinge that plate arranges contiguous its top inwall and is set in rotationally on the frame wall of smoke collecting chamber, below hinge, the air inlet at place is renovated on the inwall of plate and is provided with lug, described frame wall and air inlet are renovated between plate and are provided with and can control the air inlet mechanism for opening/closing that air inlet is renovated plate rotation, described air inlet mechanism for opening/closing comprises the motor reducer assembly being arranged on frame wall, electrical machmary maintenance cover plate, axle sleeve link assembly, hinge extension bar, axle sleeve link assembly is articulated with on the output shaft of motor reducer assembly, one end of hinge extension bar and axle sleeve link assembly are hinged, and being articulated with air inlet, renovates on the lug of plate its other end.
On above-mentioned electrical machmary maintenance cover plate, be provided with lower limit part, the bottom that this lower limit part is renovated plate with air inlet is corresponding, and when air inlet is renovated the complete closure of plate, upper edge lucky and cover plate, its lower edge coincide.
Arrange after lower limit part, when air inlet is renovated plate and closed, can effectively prevent that it from turning over head, the upper edge fitness that air inlet is renovated plate lower edge and cover plate is good, thereby avoids producing gap between the two, and therefore, it is desirable that air inlet is renovated plate closing angle.
Compared with prior art, the utility model has advantage and beneficial effect are as follows:
Because the front at smoke collecting chamber is provided with movable air inlet, renovate plate, air inlet is renovated plate and is rotated under the control of air inlet mechanism for opening/closing, has realized the open and close action that air inlet is renovated plate.When air inlet is renovated plate and opened, for oil flue waste gas, enter in smoke collecting chamber; Close-suction range hood is when stopped status; the peculiar smell of common flue easily pours in down a chimney in the utility model close-suction range hood from air-out component; and be provided with closeable air inlet, renovate after plate, can prevent that peculiar smell from coming out in smoke collecting chamber, to avoid kitchen to suffer air pollution.
Its pin joint of the other end of hinge extension bar is renovated the top inwall of plate away from air inlet, therefore, the switching motion that air inlet is renovated plate is light and handy.
