Abstract

The utility model relates to an extractor hood with a fume collection cavity capable of automatically lifting in a kitchen range hood. The extractor hood with the fume collection cavity capable of automatically lifting comprises a shell 1 of the extractor hood, an exhaust pipe 2, an air outlet seat 3, an air channel 4, a wind wheel 5 and a motor 6 and the like, and is characterized in that a movable fume collection cavity 9 which can up and down lift is arranged on the rear portion of an inner cavity of the shell 1, wherein the top portion of the movable fume collection cavity 9 is connected with the lower end of a lifter 12, and the upper end of the lifter 12 is fixed on a reinforcing rib of the shell 1, and is controlled by a control panel 7. The extractor hood with the fume collection cavity capable of automatically lifting has the advantages that the height of the fume collection cavity of extractor hood can be adjusted at random during the cooking process, thereby achieving the best fume collection effect. Compared with a common extractor hood which lifts integrally, the extractor hood with the fume collection cavity capable of automatically lifting has the advantages that the extractor hood with the fume collection cavity capable of automatically lifting does not need to often stretch and move power supply wires and the exhaust pipe, also furthest reduces lifting load, saves energy loss, reduces space usage, and prolongs service life.

Description

But a kind of range hood of smoke collecting chamber automatic lifting

One, technical field

But the utility model relates to a kind of range hood of smoke collecting chamber automatic lifting.

Two, background technology

At present, occurred a kind of kitchen ventilator with elevating on the market, it mainly is the height that hangs for the range hood that can arbitrarily adjust the kitchen range top, makes it to absorb to greatest extent the oil smoke that culinary art produces.Primary structure and the mounting means of this kitchen ventilator with elevating are: range hood integral is fixed in the thick and heavy housing, back side of shell is provided with link plate and can fixes on the wall, and being provided with the lowering or hoisting gear that is connected with range hood in the housing, whole range hood can oscilaltion in housing.This kind kitchen ventilator with elevating is found following defective after using: because lowering or hoisting gear will be born the weight of whole range hood, therefore lowering or hoisting gear is easy to damage; And the power line on the range hood, smoke exhaust pipe often be in flexible state, also is easy to wear out, breakage.

Three, summary of the invention

The utility model is for the defective of above-mentioned existence, the technical scheme of technical problem to be solved and proposition is: under the best smoking effect prerequisite that guarantees range hood, spool on the complete machine both need not be regular telescopic moving, alleviate to greatest extent again lifting load, save energy loss, dwindle and take up room, increase the service life, but invent a kind of range hood of smoke collecting chamber automatic lifting.

But the technical scheme of the range hood of a kind of smoke collecting chamber automatic lifting of the utility model is: it comprises the smoke exhaust pipe of casing top, and the smoke exhaust pipe lower end is connected with air outlet seat, and the air outlet seat lower end links to each other with the upper end, air channel, and wind wheel is housed in the air channel, and wind wheel is by driven by motor; The control panel of being furnished with shift knob is installed in casing the place ahead, but it is characterized in that arranging at the chassis cavity rear portion active set smoke chamber of an oscilaltion, active set smoke chamber top is connected with the lifter lower end, and the lifter upper end is fixed on the reinforcement of casing, and is controlled by control panel; For reducing installing space, the lifter of employing has the compact structural shape of rack-and-pinion or nut-screw; The active set smoke chamber is upright matchbox shape, top and opening is arranged towards the side in air channel, and food tray is equipped with in the bottom; The active set smoke chamber is equipped with respectively vertical guide rail near the outer wall of casing and casing near the inwall of active set smoke chamber, and two guide rails cooperatively interact, when the guide rail on the active set smoke chamber moves up and down by the guide rail on the casing as guiding.

Four, description of drawings

But Fig. 1 is the range hood schematic diagram of a kind of smoke collecting chamber automatic lifting of the utility model.

Among the figure: 1, casing; 2, smoke exhaust pipe; 3, air outlet seat; 4, air channel; 5, wind wheel; 6, motor; 7, control panel; 8, oil box; 9, active set smoke chamber; 10,11, guide rail; 12, lifter.

Five, the specific embodiment

But be described further below in conjunction with the implementation process of accompanying drawing to the range hood of a kind of smoke collecting chamber automatic lifting of the utility model:

(1), manufacture process:

According to the requirement on the design drawing:

1. purchased the smoke exhaust pipe 2 of certain specification, air outlet seat 3, wind wheel 5, motor 6, the outsourcing pieces such as lifter (assembly) 12 and stainless sheet steel.

2. via plate shearing machine, bender, the equipment such as bonding machine and polishing machine process casing 1, active set smoke chamber 9, guide rail 10, the sheet metal components such as 11, and guide rail 10 and guide rail 11 are separately fixed on the inwall of the outer wall of active set smoke chamber 9 and casing 1.

3. with reference to the part assembling drawing and the general assembly drawing that design, wind wheel 5, motor 6 are installed in the air channel 4, air channel 4 and air outlet seat 3, smoke exhaust pipe 2 coupled together be fixed on casing 1 inner chamber central authorities, and on casing 1 inner chamber rear portion is fastened on the upper end of lifter 12 a reinforcement in the casing 1, the top of lower end and active set smoke chamber 9 is affixed, simultaneously the guide rail 11 on the inwall of the guide rail 10 on the outer wall of active set smoke chamber 9 and casing 1 is cooperatively interacted; Then the two-way reducing motor (not shown) of lifter 12 by circuit and control panel 7 UNICOMs, and make all circuit UNICOMs such as wiring board (not shown) in control panel 7 and the casing 1 and motor 6.

(2), use procedure:

When beginning culinary art, when producing oil smoke in the kitchen, press the shift knob on the control panel 1, the power motor 6 of wind wheel 4 and the two-way reducing motor of lifter 12 start synchronously: the negative pressure in the air channel 4 increases gradually, the lifter 12 at casing 1 inner chamber rear portion lands (the travel switch control that the amplitude of landing is linked to each other with lifter 12 by control panel 7) gradually, and the oil smoke in the kitchen just namely is discharged into outdoor by the wind wheel 5 of High Rotation Speed from air outlet seat 3, smoke exhaust pipe 2 via lateral opening, open top, casing 1 inner chamber rear portion to the air channel 4 of active set smoke chamber 9.In the whole discharge process of range hood, as the emission effect of feeling oil smoke is unsatisfactory, just can press at rising button or the decline button of control panel 7 control lifters 12, adjust smoke collecting chamber from the height of kitchen range, it is reached till the best smoking effect.When culinary art finishes, oil smoke discharge stops (can allowing range hood work for a moment again, make airborne greasy smell complete obiteration), just press (such as inductive switch at control panel 7, then touch) close key once, the motor 6 that drives wind wheel 5 just stops operating, negative pressure in the machine dies down, and at this moment, active set smoke chamber 9 also enters the inner chamber rear portion of casing 1 under the Synchronous lifting of lifter 12.The greasy peculiar smell of having stopped in the machine that remains in distributes to outdoor, kept the pure of air in the kitchen.
