Abstract

The invention relates to a range hood with an automatically-lifted smoke collection cavity, belonging to range hoods for a kitchen. The range hood comprises a machine shell (1), a smoke discharging pipe (2), an air exhausting seat (3), an air duct (4), an air wheel (5), a motor (6) and the like. The innovation point of the range hood is that a movable smoke collection cavity (9) capable of being lifted up and down is formed in the rear part of an inner cavity of the machine shell (1), the top of the movable smoke collection cavity (9) is connected with the lower end of a lifter (12), the upper end of the lifter (12) is fixed on a reinforcing rib of the machine shell (1), and the lifter (12) is controlled by a control panel (7). The range hood has the superiorities that the height of the smoke collection cavity of the range hood can be arbitrarily regulated in a cooking process, thereby achieving an optimal smoke exhausting effect. Compared with a conventional integrally-lifted range hood, the range hood has the advantages that power supply lines and the smoke discharging pipe do not need to be frequently stretched and moved, the lifting load is maximally alleviated, the energy consumption is saved, the occupied space is reduced, and the service life is prolonged.

Description

A kind of smoke collecting chamber can automatic lifting range hood

One, technical field

The present invention relates to the range hood that a kind of smoke collecting chamber can automatic lifting.

Two, background technology

At present, occurred a kind of kitchen ventilator with elevating on market, it is mainly the height hanging in order arbitrarily to adjust the range hood of 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 a thick and heavy housing, back side of shell is provided with link plate and can fixes on the wall, and in housing, being provided with the lowering or hoisting gear being connected with range hood, whole range hood can oscilaltion in housing.This kind of kitchen ventilator with elevating found following defect 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 range hood, smoke exhaust pipe are often in flexible state, are also easy to aging, damaged.

Three, summary of the invention

The present invention is directed to the defect of above-mentioned existence, the technical scheme of technical problem to be solved and proposition is: guaranteeing under the best smoking effect prerequisite of range hood, spool on 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, invent the range hood that a kind of smoke collecting chamber can automatic lifting.

A kind of smoke collecting chamber of the present invention can automatic lifting the technical scheme of range hood be: it comprises the smoke exhaust pipe of casing top, and smoke exhaust pipe lower end is connected with air outlet seat, and air outlet seat lower end is connected with upper end, air channel, and wind wheel is housed in air channel, and wind wheel is by driven by motor; The control panel of being furnished with shift knob is arranged on casing the place ahead, it is characterized in that arranging at chassis cavity rear portion one can oscilaltion active set smoke chamber, active set smoke chamber top is connected with lifter lower end, and lifter upper end is fixed on a 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; Active set smoke chamber is upright matchbox shape, top and have opening towards the side in air channel, and food tray is equipped with in bottom; 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 active set smoke chamber moves up and down by the guide rail on casing as guiding.

Five, the specific embodiment

The implementation process of range hood that can automatic lifting to a kind of smoke collecting chamber of the present invention below in conjunction with accompanying drawing is described further:

(1), manufacture process:

According to the requirement on 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, the sheet metal components such as guide rail A10, guide rail B11, and guide rail A10 and guide rail B11 are separately fixed on the outer wall of active set smoke chamber 9 and the inwall of casing 1.

3. with reference to the part assembling drawing and the general assembly drawing that design, wind wheel 5, motor 6 are arranged in air channel 4, air channel 4 and air outlet seat 3, smoke exhaust pipe 2 are coupled together and be fixed on casing 1 inner chamber central authorities, and the upper end of lifter 12 is fastened on the reinforcement in casing 1 at casing 1 inner chamber rear portion, the top of lower end and active set smoke chamber 9 is affixed, the guide rail B11 on the inwall of the guide rail A10 on the outer wall of active set smoke chamber 9 and casing 1 is cooperatively interacted simultaneously; Then the two-way reducing motor of lifter 12 and travel switch (not shown) by circuit and control panel 7 UNICOMs, and make all circuits such as wiring board (not shown) in control panel 7 and casing 1 and motor 6 UNICOM.

(2), use procedure:

When starting culinary art, while producing oil smoke in kitchen, press the shift knob on control panel 1, the power motor 6 of wind wheel 4 and the two-way reducing motor of lifter 12 synchronously start: the negative pressure in air channel 4 increases gradually, the lifter 12 at casing 1 inner chamber rear portion lands (amplitude of landing is controlled with the travel switch that lifter 12 is connected by control panel 7) gradually, and the oil smoke in kitchen is just 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 unsatisfactory in the emission effect of feeling oil smoke, just can on control panel 7, control on the rising button of lifter 12 or decline button and press, adjust smoke collecting chamber from the height of kitchen range, till making it reach best smoking effect.When culinary art finishes, oil smoke discharge stops (can allowing range hood work for a moment again, airborne greasy smell is disappeared completely), just at control panel 7, press (as inductive switch, touch) close key once, drive the motor 6 of wind wheel 5 just to stop operating, negative pressure in machine dies down, and now, 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 to remain in machine distributes to outdoor, kept the pure of air in kitchen.
