Abstract
The utility model discloses a folding cooking fume removing machine used for removing the cooking fume in the kitchen, solving the problems of small suction volume and large occupation space existing in the prior art, which is characterized in that the vertical type mounting structure is adopted, a folding suction cover which can open and close with the start and the stop of a scavenger fan is provided, improving the effect of removing cooking fume. The utility model has the advantages of convenient installation, and little space occupation. The utility model is accompanied by an enclosed type gas ignitor, which only can ignite the fire when the harmful gases in the room isn't out of the limit, preventing from the combustible gas explosion.
Description
The utility model relates to a kind of smoke exhaust ventilator, is used to get rid of the pernicious gas in the kitchen.
The smoke exhaust ventilator of existing use is seen all from general structure and partly to be made up of shell, air-suction cover, ventilating fan, speed control, pernicious gas monitoring etc.Because the air-suction cover of this class smoke exhaust ventilator is the flat type of fixing, and can not install low, so suction capactity a little less than.Because of adopting cantilevered to install, An Detai is low, can take the kitchen lower space, and not harmony influences decorative effect, hinders the kitchen operation.
The purpose of this utility model provides a kind of folding fume extractor, this smoke pumping function overcome existing smoke exhaust ventilator inspiratory effects poor, take kitchen space greatly, shortcoming such as not attractive in appearance, this machine also is provided with enclosed type electric pulse gas igniter simultaneously, when fuel gas transfinites in the kitchen, the igniter spark that do not generate electricity prevents flammable gas explosion.
Task of the present utility model is achieved through the following technical solutions: this folding fume extractor adopts vertical mounting structure, be provided with collapsible air-suction cover, air-suction cover is made of the collapsible sector of both sides and the flat cover on top, opening and folding by small machine of air-suction cover carried out automatically through decelerator control, and ventilating fan opens along with air-suction cover and folds automatic start and stop.
The ignition power that the utility model is set up is supplied with by this machine control circuit, and when indoor fuel gas transfinited, control circuit cut off ignition power immediately, made it that electric spark can not take place.
The advantage that the utility model compared with prior art has is: the smoking ability is strong, and it is little to take up room, and harmony attractive in appearance is installed, and is safe and convenient to use.
Existing smoke exhaust ventilator air-suction cover is a hither plane shape, inspiratory effects is poor, and the smoke exhaust ventilator of this horizontal safety assembling structure must take cantilevered to install, and installs low to take indoor lower space bigger, not attractive in appearance, not harmony, influence decorative effect, hinder office operation sometimes, installed high and unfavorable smoke discharging, flue gas easily spreads, and pollutes indoor environment.
The utility model smoke exhaust ventilator, adopt the folding air-suction cover, when the start smoke evacuation, air-suction cover opens automatically, forming both sides is that sector top is the bucket-shaped air-suction cover of downward-sloping flat cover, and it is effective that this air-suction cover is collected flue gas, at the cover mouth certain suction gas speed is arranged, so compare with flat air-suction cover, the smoke discharging ability strengthens.When closing smoke exhaust ventilator, air-suction cover is retracted to initial position automatically, forms the perpendicular flat casing of flat, is affixed on the metope, and it is little therefore to take up room, and good decorating effect does not hinder other office operation.Admittedly can reduce setting height(from bottom), from and the smoke discharging effect is strengthened.
In addition, the utility model is also with enclosed type electric pulse gas igniter, and when indoor fuel gas transfinited, supervisory circuit is cut off ignition power, and it is not worked, and prevents gas burst, and was not only easy to use, and safety.
The drawing of accompanying drawing is described as follows: Fig. 1 is a schematic perspective view of the present utility model, and Fig. 2 is the circuit theory sketch.
Embodiment of the present utility model is described below with reference to the accompanying drawings: this folding fume extractor is not when starting shooting, shell 10 is flat casing, be provided with ventilating fan 11 in the middle and upper part of housing 10, the control panel of smoke exhaust ventilator is located at a side of housing 10, be provided with the startup of smoke exhaust ventilator in the bottom of control panel and close switch 1, ventilating fan suspends and automatic pilot switch 2, the middle part is a turn-knob 3 of regulating the ventilating fan rotating speed, top is the sensor 4 and the alarm 5 of harmful gas automatic monitoring system, and all electric components all are installed in the shell of control panel rear portion.Air-suction cover is that collapsible fan-shaped shield 12 and the flat cover 9 by both sides constitutes, the upper end of air-suction cover flat cover 9 and axostylus axostyle 8 are fixing, and swing with the rotation of axostylus axostyle 8, each big covering of the fan is made up of several little covering of the fans, one end of little covering of the fan all is placed on the axostylus axostyle 8, collude connection mutually by the knuckle on the edge between the little covering of the fan, the big covering of the fan 12 of generate when flat cover 9 is upwards swung, little covering of the fan was combined into a branch of being hidden in the shell when air-suction cover folded.Axostylus axostyle 8 links by the axle of worm type of reduction gearing 7 with dc motor 6, the shell of direct current generator 6 is fixed on the smoke exhaust ventilator housing 10, the enclosed type gas igniter hangs in the groove of smoke exhaust ventilator housing 10 front surfaces setting, and ignition power is supplied with by the telescopic lead of a segment length by control circuit.
Button with switch 1 during exhaust places " ON " state, its K
1-2The power supply of contacting control circuit, K
1-1The contact forward is connected the power supply of direct current generator 6, and the winding of electric current from the positive pole of power supply to direct current generator 6 is through the normally-closed contact JK of machine control switch 13
2-1Flow to negative pole, motor 6 rotates to positive direction, after slowing down, worm type of reduction gearing 7 passes to axostylus axostyle 8, making axostylus axostyle drive the air-suction cover flat cover 9 that fixes with it upwards opens, the sector 12 of both sides launches thereupon, when air-suction cover flat cover 9 forwards to when vertically becoming 80 degree angles, the control lever quilt of machine control switch 13 presses its normally opened contact JK with the feeler lever of flat cover 9 interlocks
2-2Closure, pause switch K at this moment
2Be in on-state, the power supply of ventilating fan 11 is switched on, and makes its running, at the normally opened contact JK of machine control switch 13
2-2After the closure, its normally-closed contact JK
