Description
Technical field
The present invention relates to close-suction range hood technical field more particularly to a kind of telescopic near-suction type smokes of air inlet
Machine.
Background technology
The kitchen ventilator of commercial type mainly includes two kinds of European-style range hood and side-suction type range hood at present.It is marked according to country
Accurate regulation, the height of the bottommost of European-style range hood apart from hearth must not be less than 600mm, the bottommost of side-suction type range hood away from
Height from hearth must not be less than 350mm.And European-style range hood and side-suction type range hood all use fixed structure substantially, it is impossible to
Adjust the distance between fume exhauster air inlet and hearth.The oil smoke generated in cooking process, guarantee are siphoned away in order to as much as possible
Powerful suction, it is necessary to increase the power of wind turbine, therefore production cost, Energy in use etc. is caused to improve, is big etc. using noise
Defect.
It, all can to the greatest extent can in order to farthest suck oil smoke in addition, either European-style range hood or side-suction type range hood
Energy ground expands the area of inlet scoop, necessarily so that kitchen ventilator is stretched out toward operating space, the reduction of cooker operating space, event of colliding with
It emerges in an endless stream.
Individually, a part of manufacturer is the contradiction overcome between fume exhauster air inlet height and smoke machine power, is produced
Adjustable fume exhauster：Such as China Patent No. be CN203421763U, the Chinese utility model patent of entitled lift kitchen ventilator,
Disclose a kind of lift kitchen ventilator, including the induced-draught electric motor and impeller built in casing and casing, casing lower part be provided with into
Air port, air inlet rear are additionally provided with movable air-intake device in casing, and movable air-intake device can under the traction of lifting device
To be moved up and down in casing.Technical solution disclosed in the utility model at the rear of air inlet, be equipped with and live in casing
Dynamic air-intake device.Kitchen ventilator in the utility model on the top of hearth and side due to being equipped with air inlet so that motor
Power becomes larger, and easily burns out motor and causes the waste of the energy.Simultaneously as hearth top also is provided with air inlet so that oil smoke
Plane where the upper air inlet of machine has more stretched into operating space, reduces operating space, phenomenon of easily colliding with.
Invention content
To overcome the shortcomings of above-mentioned technical proposal, the present invention provides a kind of power of fan is small, cooker operation is convenient, cigarette
Machine small volume, the telescopic close-suction range hood of air inlet that appearance globality is strong, smoking effect is apparent, noise is low.
The present invention mainly adopts the following technical scheme that：
A kind of telescopic close-suction range hood of air inlet, including casing and the blower fan system being installed in the casing, institute
The inside for stating casing is formed with smoke collecting chamber, and the front end of the smoke collecting chamber is provided with panel, and the bottom of the casing is provided with and can stretch
The air intake assembly of contracting, the lower part of the air intake assembly are provided with air inlet, and the air inlet is in the extended state apart from hearth height
It spends for 250mm to 340mm.The invention also includes following attached technical schemes：
Wherein, the blower fan system includes turbine assembly, and the turbine assembly includes volute, the turbine mutually assembled and whirlpool
Plate in wheel, is provided with air-ducting ring on the volute, and the motor shaft of electric rotating machine passes through plate in the turbine.
Wherein, supercharging blade is equipped in the end of the motor shaft and volute between plate, the rotation of the supercharging blade is straight
The diameter ratio of diameter and turbine is 0.3 to 0.7.
Wherein, the air inlet is set to the lower front part of the air intake assembly, the inside of the air intake assembly with it is described
Smoke collecting chamber is connected.
Wherein, the air inlet is set on the shell of the air intake assembly, and the air inlet has air intake plate, described
Air inlet hole is provided on air intake plate.
Wherein, the air inlet is set on the shell of the air intake assembly, and the air inlet is movably disposed within
Air intake plate.
Wherein, the air intake plate is set to the air inlet by rotary drive mechanism and/or translational drive mechanism.
Wherein, the rotating diameter of the supercharging blade and the diameter ratio of turbine are 0.4 to 0.5.
Wherein, the panel is glass panel.
Above-mentioned technical proposal provided by the present invention, towards cooker one side for monolithic devices glass panel, appearance is high-grade,
Convenient for cleaning；Air inlet is telescopically arranged in the bottom of smoke collecting chamber, and air inlet stretches out collection when kitchen ventilator is in running order
Smoke chamber, air inlet bounces back to smoke collecting chamber, air inlet when the moulded beautiful, smoke machine of smoke machine does not work when kitchen ventilator is stopped
It is invisible in appearance；The bottom of smoke collecting chamber is set to since air inlet is telescopic so that height of the air inlet apart from hearth
350mm can be less than.The oil smoke generated in cooking process is not spread also to be siphoned away by smoke machine, without additionally increase power of fan or
Person, which increases smoke machine volume, can ensure that smoke machine has stronger smoking effect；This kind of structure setting but also smoke machine it is whole it is more slim,
Cooker has the operating space of bigger, avoids colliding with；This kind of structure design makes the air draught of turbine increase with obvious effects, so as to
It improves fan efficiency and reduces noise, simultaneously as the length of supercharging blade is smaller so that only can there are seldom on blade
Greasy dirt, the weight of blade will not be aggravated, suction effect is enhanced, reduce noise.
