Abstract

The utility model relates to a range hood with a manually-elevated smoke chamber, belonging to kitchen range hoods. The range hood comprises a shell 1, a smoke vent 2, an air-out base 3, an air flue 4, an air wheel 5, and a motor 6. The range hood is characterized in that two gears 12 which are meshed with each other and an electromagnetic switch 11 are arranged on the rear wall of the smoke chamber 9, and two racks 13 in parallel are vertically fixed on the rear wall of the shell 1. Due to the simple structure, a housewife can adjust the height of the smoke chamber by the hand during cooking, and compared with a range hood with a automatically-elevated smoke chamber, the range hood cancels a bidirectional speed-reduction motor for driving the smoke chamber to be elevated and simplifies a complex elevation linkage mechanism, and the power consumption is reduced. Therefore, the range hood is relatively low in cost, applicable to rural families which are not rich at present, and has a wide sale market.

Description

But a kind of range hood of smoke collecting chamber hand-operated lifting

One, technical field

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

Two, background technology

Recently, in the range hood research and development, the height hung in order arbitrarily to adjust kitchen range top range hood, make it to absorb to greatest extent the oil smoke produced in culinary art, invented a kind of kitchen ventilator with elevating at home.Afterwards, must bear the caused parts strain of whole range hood weight for fear of this range hood its device when the lifting, so invented a kind of with two-way reducing motor drive, " but the range hood of a kind of smoke collecting chamber automatic lifting " of the lifter that gear, tooth bar or nut, screw rod be transmission mechanism of take (is shown in my patent, the patent No.: 201220503378.X).Nowadays, be Cost reduction and the national conditions of catering to China, I develop again a kind of relative low price, energy consumption less, simple in structure, service-strong " but range hood of a kind of smoke collecting chamber hand-operated lifting ".

Three, summary of the invention

The technical scheme of the utility model " but range hood of a kind of smoke collecting chamber hand-operated lifting " is: it comprises casing, smoke exhaust pipe, air outlet seat, air channel, wind wheel, motor, button, active set smoke chamber, food tray, guide rail forms, 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 casing as guiding; It is characterized in that installing intermeshing two gears on the smoke collecting chamber rear wall, one electromagnetic switch (electromagnetic valve switch is by pressing key control) is set in the gear back, and vertically fix two parallel tooth bars on the casing rear wall, when smoke collecting chamber enters in casing, two gears are between two tooth bars, and the teeth of two gears are meshed with the teeth of tooth bar.Owing to two pitch wheels being installed on the smoke collecting chamber rear wall and vertically having fixed two parallel tooth bars on the casing rear wall; Particularly in the back of gear, be provided with by the electromagnetic switch by key control, this electromagnetic switch can be controlled on the arbitrary height of smoke collecting chamber in deadweight decline process and stop, and smoke collecting chamber need rise the time magnetic valve can break away from the obstruction to two meshing gears, now only need manpower can hold up to certain altitude relief magnetic valve multiple to hinder it, make it stable.Therefore can save and drive the two-way reducing motor of smoke collecting chamber lifting and the lifting link-gear of more complicated, power consumption is little.Be a kind of cheap, energy consumption is little, simple in structure, service-strong " but range hood of a kind of smoke collecting chamber hand-operated lifting ".

Five, the specific embodiment

But the implementation process below in conjunction with accompanying drawing to the range hood of a kind of smoke collecting chamber hand-operated lifting of the utility model 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 and button 7, electromagnetic switch 11, gear 12, the outsourcing pieces such as tooth bar 13 and stainless sheet steel.

2. via plate shearing machine, bender, the equipment such as bonding machine and polishing machine process casing 1, air channel 4, smoke collecting chamber 9, the sheet metal components such as guide rail A10, guide rail B14, and guide rail A10 and guide rail B14 are separately fixed on the inwall of the outer wall of smoke collecting chamber 9 and casing 1.

3. two gears 12 and electromagnetic switch 11 are fixed on to smoke collecting chamber 9 rear wall middle and upper parts (electromagnetic switch 11 is in the back of two gears 12) and make two gears 12 intermeshing, again on and the parallel rear wall that is fixed on casing 1 vertical two tooth bars 13, and make respectively its teeth be meshed with the teeth of two gears 12 (seeing Fig. 3).

4. 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, from the lifting that makes progress of casing 1 back space, the guide rail B14 on the inwall of guide rail A10 on the outer wall of smoke collecting chamber 9 and casing 1 is cooperatively interacted; Then electromagnetic switch 11 by button 7 UNICOMs on circuit and control panel, and make all circuits such as wiring board (not shown) in control panel and casing 1 and motor 6 UNICOM.

(2), use procedure:

When starting culinary art, while in kitchen, producing oil smoke, the culinary art housewife only need be with hand below smoke collecting chamber 9 or avris buttress and press the button 7 on control panel, be positioned at electromagnetic switch 11 ends of gear 12 back with regard to indentation, now, smoke collecting chamber 9 is slowly decline (meanwhile two gears 12 engagement rolling in two tooth bars 13) under the self gravitation effect, when smoke collecting chamber 9 reaches desired height, press button 7 with hand again, just stretch out electromagnetic switch 11 ends, be stuck in the teeth groove of a gear 12 wherein, gear 12 just stops rolling, and smoke collecting chamber 9 just stops at desired height.And when smoke collecting chamber 9 needs to rise, then press the button 7 on control panel, and gently upwards hold up with have gentle hands, press button 7 to certain altitude and get final product.Through use, facts have proved, due to 9 of smoke collecting chambers, as empty capsid, two pinions 12 and a slight electromagnetic switch 11 have only been installed in inside, and the housewife with culinary art ability can accomplish easily fully when adjusting the smoke collecting chamber height.Simultaneously, this structure with hand adjustment joint smoke collecting chamber height, compare with invention before me " but range hood of a kind of smoke collecting chamber automatic lifting ", can save and drive the two-way reducing motor of smoke collecting chamber lifting and the lifting link-gear of more complicated, and reduce power consumption.Therefore, comparatively speaking, cost is lower, more adapts to the vast still not rich rural households of current China, has more wide selling market.
