Abstract

The utility model discloses a device for a balance expansion kitchen ventilator, and the device is composed of a kitchen ventilator hood, a movable oil fume hood, an up and down balance block, a steel wire rope, a front pulley and a back pulley. The utility model is characterized in that the movable oil fume hood is connected with the kitchen ventilator hood by an up and down sliding positioning guideway, the movable oil fume hood and the up and down balance block are hung between the front pulley and the back pulley through the drag steel wire rope, so the movable oil fume hood which firmly slides up and down and steadily moves is formed.

Description

The telescopic range hood of balance

The utility model relates to the telescopic range hood of a kind of balance, specifically just a kind of height of oil smoke hood range hood that can stretch up and down.

From existing market sell range hood, mainly contain two big classes: a class is that " shallow bell-type " general this form all is equipped with a pair of range hood; Another kind of is " dark bell-type ", this also is the just new in recent years kind of releasing, its smoke evacuation ability is better than " shallow bell-type " slightly, but they all have a common shortcoming, can not install too highly exactly, higher as adorning slightly, the ability of oil suction cigarette will descend greatly, that is to say to adorn well more near the kitchen sink more.But adorn low can to give and use and operation brings great inconvenience, thus this group contradiction they can't solve always.Be unconfined power, just inspiratory capacity is done bigger and bigger.Thing followed electrical problem, noise problem have produced again like this.There is producer to release a kind of " luring formula " range hood recently again, its feature be lampblack-sucking cover can install relatively low, because its oil smoke cover is above gas range interior, coal gas platform top is a semi-open form, but the user worries it is its real function oil suction cigarette ability most, from objective analysis, because the oil smoke hot gas that it spatters outside will reaching when culinary art rising naturally changes direction all obeyiently, inspiration some difficulty whether in its far oil smoke cover is unless it does inspiratory capacity very greatly.

The purpose of this utility model is to provide a kind of cover tool that can move up and down, when you need can it draw very low (near the kitchen sink) you can make things convenient for high and low's mobile cover tool easily when the kitchen sink is worked when you, can not influence your operation at all.The assorted gas of the oil smoke of all is controlled in the cover, lampblack absorber is very light just can discharge waste gas outdoor, so it will be the range hood of utility model the most of new generation.

In order to achieve the above object, the utility model adopts following technical scheme: it by can move oil smoke cover, balance weight, rail plate, steel wire rope and front wheel, rear wheel are formed up and down.In the both sides that can move oil smoke cover the location rail plate is housed, can moves the front shroud position of oil smoke cover with wire rope hanging, through front wheel, rear wheel links to each other with balance weight up and down.

The utility model is considered particular job environment of range hood when design, consider that also being convenient to the user cleans, so the guiding theory in when design is for mechanically to the greatest extent can be simple, reliably, safety, " balance the is telescopic " principle that adopted, just weight is housed and can moves the thing piece that oil smoke cover equates at the another side that can move oil smoke cover, two ends connect by pulley with steel wire rope, when the situation lower sheave both sides in no applied external force are equal in weight, keep poised state, you are as long as can move on the oil smoke cover handgrip slightly one firmly when you want to change the height that can move oil smoke cover, and the pulley both sides are under the effect of centre-of gravity shift, and then you move up and down freely, a whole set of design indicates one ingenious, high and low that can be easily again can be reliable, safety in oil smoke high temperature director time service.Making, process, install all is simple, convenient.

Below in conjunction with accompanying drawing, the utility model is elaborated

Accompanying drawing is the utility model example schematic diagram

As shown in the figure, location rail plate (7) is equipped with in the both sides that can move oil smoke cover (2), hangs the front shroud position that can move oil smoke cover (2) with steel wire rope (3), passes through front wheel (4), and rear wheel (5) links to each other with balance weight (6) up and down.When not needing the time spent, you can not move on to mobile oil smoke cover (2) in the lampblack absorber outer cover (1), when you need the time spent, leave behind it, the whole like this kitchen sink (8) is substantially all covered by oil smoke cover so long, and the assorted gas of all oil smoke that produced in the nature pot is easy to and is discharged from outdoor.
