Abstract

The utility model discloses a range hood which comprises a shell, an exhaust fan, an oil screen and a smoke collecting cover, wherein, an electric motor case is arranged inside the shell; the exhaust fan is arranged inside the electric motor case; the oil screen is fixed on the bottom surface of the electric motor case; a lifting gear is arranged on the electric motor case. Because the electric motor case is arranged inside the shell and the lifting gear is arranged on the electric motor case, the lifting gear can make the electric motor case move up and down, thereby the distance of an air inlet on the oil screen and a range surface can be adjusted and the distance resulting in better smoke removal effect can be adjusted. Moreover, because the electric motor case moves up and down in the shell, not only the beautiful appearance of the whole range hood is reserved but also the space occupied by vertical movement of the electric motor case is smaller.

Description

A kind of smoke exhaust ventilator

Technical field

The utility model relates to the cooking apparatus technology, is specifically related to a kind of smoke exhaust ventilator.

Background technology

Along with the raising day by day of people's living standard, people are more and more higher to the sanitary requirement in quality of life and kitchen, and smoke exhaust ventilator has become the cooking apparatus commonly used of average family.The structure of smoke exhaust ventilator comprises exhaust fume collecting hood and casing, in casing, be provided with air exhauster, air exhauster one end is connected with exhaust hose, the air exhauster other end is connected with soft air-guide pipe, between casing and exhaust fume collecting hood, be provided with panel, be provided with oily net on panel, oily net is fixedlyed connected with the soft air-guide pipe front end, and the mesh of oil net is the air inlet of smoke exhaust ventilator just.The casing and the exhaust fume collecting hood of existing most smoke exhaust ventilators are fixedly connected on one, the distance that therefore rear air inlet and kitchen range face are installed is also just fixing, if the close together of air inlet and kitchen range face, though flue gas velocity is very fast, be unfavorable for disturbing cigarette, the part oil smoke just is diffused in the kitchen, influenced the environmental sanitation in kitchen, if the distance of air inlet and kitchen range face is far away, flue gas velocity is just slower, also influences the environmental sanitation in kitchen.In order to reach smoke discharging effect preferably, some lampblack absorber is provided with the complete machine elevating mechanism, though can regulate the distance of air inlet and kitchen range face, reach smoke discharging effect preferably, but complete machine moves up and down, its energy consumption is bigger, and taken bigger mobile space, installation requirement is also higher; Some lampblack absorber is set to exhaust fume collecting hood can be separated with casing, the mechanism that exhaust fume collecting hood can move up and down, so just can regulate the distance of air inlet and kitchen range face, reach smoke discharging effect preferably, but moving of exhaust fume collecting hood also will take bigger mobile space, and exhaust fume collecting hood separates the overall appearance that has also influenced lampblack absorber with casing.

Summary of the invention

The distance that technical problem to be solved in the utility model provides a kind of air inlet that can regulate lampblack absorber and kitchen range face takies the smoke exhaust ventilator of less mobile space again.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of smoke exhaust ventilator, comprise casing, air exhauster, oily net and exhaust fume collecting hood, be provided with the motor case in the described casing, described air exhauster is arranged in the described motor case, described oily net is fixedly installed on the bottom surface of described motor case, and described motor case is provided with lowering or hoisting gear.

Described lowering or hoisting gear comprises drive motors and slide mechanism, described drive motors is fixed on the described casing, described drive motors is provided with up position-sensing switch, descending position-sensing switch and transmission rope, described transmission rope is provided with locating piece, and described locating piece is fixed on the described motor case.

Described slide mechanism comprises slide rail and the slide block that cooperatively interacts, and described slide rail is fixed on the described casing, and described slide block is fixed on the described motor case.

Described up position-sensing switch and described descending position-sensing switch are fixed on the described casing.

Compared with prior art, advantage of the present utility model is owing to be provided with the motor case in casing, air exhauster is arranged in the motor case, the oil net is fixedly installed on the bottom surface of motor case, the motor case is provided with lowering or hoisting gear, lowering or hoisting gear can make the motor case move up and down like this, can regulate the online air inlet of oil and the distance of kitchen range face, can be adjusted to the distance of smoke discharging effect preferably, again because the motor case is to move up and down in casing, so not only kept the attractive in appearance of smoke exhaust ventilator integral body, and the motor case to move up and down shared space less.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Embodiment 1

As Fig. 1, Fig. 2 and a kind of smoke exhaust ventilator shown in Figure 3, comprise casing 1, the air exhauster (not shown), oil net 3 and exhaust fume collecting hood 2, be provided with motor case 4 in the casing 1, air exhauster is arranged in the motor case 4, oil net 3 is fixedly installed on the bottom surface of motor case 4, the motor case is provided with lowering or hoisting gear, lowering or hoisting gear comprises drive motors 51 and slide mechanism, drive motors 51 is fixed on the casing 1, drive motors 51 is provided with up position-sensing switch 71, descending position-sensing switch 72 and transmission rope 53, up position-sensing switch 71 is fixed on the casing 1 with descending position-sensing switch 72 and is connected with drive motors 51 lines respectively, transmission rope 53 is provided with locating piece 52, and locating piece 52 is fixed on the motor case 4, and slide mechanism comprises slide rail 61 and the slide block 62 that cooperatively interacts, slide rail 61 is fixed on the casing 1, and slide block 62 is fixed on the motor case 4.

Operation principle of the present utility model is, as shortening the distance of air inlet and kitchen range face, just start descending position-sensing switch 72, drive motors 51 rotates like this, make locating piece 52 descending by transmission rope 53, locating piece 52 descending makes the descending of motor case 4, and the descending slide block 62 of motor case 4 that just is fixed on of motor case 4 is from slide rail 61 toward lower slider, when slide under the air inlet on the oily net 3 of motor case 4 bottom surfaces with the kitchen range face need apart from the time, close descending position-sensing switch 72; As strengthening the distance of air inlet and kitchen range face, as long as start up position-sensing switch 71 equally.
