Description

An adjustable range hood

technical field

The utility model relates to the technical field of range hood equipment, in particular to an adjustable range hood.

Background Art A range hood, also known as a range hood, is a kitchen appliance that purifies the kitchen environment. Outdoors, it reduces pollution, purifies the air, and has anti-virus and explosion-proof safety guarantees. Range hoods have become indispensable kitchen equipment for modern families. Currently, household range hoods sold on the market generally have two forms, one The metal shell of the wind gathering hood forms two parallel planes corresponding to the cooktop, and a negative pressure zone is formed between the cooktop and the range hood to meet the purpose of exhausting the oil fume. Due to the limitation of the installation position, the distance between the cooktop and the range hood is too large The range hood is too large, the oil fume cannot be completely eliminated, and the distance between the stove and the range hood is too small, which affects the operation. Another range hood adopts a sloped wind gathering hood to form an angle with the stove top, although it eliminates operational problems. It is inconvenient, but the negative pressure zone formed by the slope still has a certain influence on the exhaust rate of the range hood, which cannot meet the requirements of the modern home living environment.

Utility model content

The purpose of this utility model is to provide an adjustable range hood to solve the problems raised in the above-mentioned background technology. High, energy saving and environmental protection.

In order to achieve the above purpose, the utility model provides the following technical solutions: an adjustable range hood, including an air duct, a smoke collection hood, an oil filter and a stepping motor, the front end of the smoke collection hood is equipped with an oil filter, The top of the oil filter screen is provided with a baffle, and a display and an operation button are fixed on the baffle, an oil collection tank is provided at the bottom of the smoke collection hood, and an oil discharge port is provided on the side of the oil collection tank, and the left and right sides of the smoke collection hood Gear slots are arranged inside, and gears are installed inside the gear slots, and the gears are fixed on the outside of the air duct through bearings. An exhaust fan is installed inside the air duct, and the stepping motor is fixed on the left side of the inner wall of the air duct. The driving wheel on the stepping motor is rotationally connected with the driven wheel on the rotating shaft through a belt, and the rotating shaft is arranged at the bottom of the air duct through a bearing, and gears are installed at the left and right ends of the rotating shaft.

Preferably, there are four gears, which are respectively fixed on the bearing and the rotating shaft.

Preferably, the display is arranged on the left side of the operation button.

Preferably, the stepper motor is arranged at the junction of the air duct and the fume collection hood.

Preferably, the gear and the gear groove are in a rolling connection.

Compared with the prior art, the beneficial effect of the utility model is that the smoke collecting hood of the equipment is in the form of a slope, which can be installed on the wall of the kitchen, which reduces the use space and effectively prevents the operator from using it due to oil fume removal. The position of the machine is too low and the head is hurt. This new model adopts the form of gears and rotating shafts to change the connection form between the fume collection hood and the air duct from the traditional fixed connection to an adjustable mobile connection. When the kitchen fume is too large , the operator can change the elongation and angle of the fume collection hood through the control button to achieve the best fume extraction effect and increase the fume extraction efficiency, thereby reducing energy usage and achieving the goal of energy saving and environmental protection.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figures 1-3, an embodiment provided by the utility model: an adjustable range hood, including an air duct 1, a smoke collection hood 4, an oil filter 7 and a stepping motor 14, and the front end of the smoke collection hood 4 An oil filter 7 is installed on the top of the oil filter 7, and a baffle 3 is arranged on the top of the oil filter 7, and a display 5 and an operation button 2 are fixed on the baffle 3, and an oil collecting tank 6 is arranged at the bottom of the smoke collecting hood 4, and the side of the oil collecting tank 6 is arranged There is an oil discharge port 11, and the left and right sides of the fume collecting hood 4 are provided with gear grooves 10 inside. The gear groove 10 is equipped with a gear 8, and the gear 8 is fixed on the outside of the air duct 1 through a bearing 13, and an exhaust fan 9 is installed inside the air duct 1. , the stepping motor 14 is fixed on the left side of the inner wall of the air duct 1, the driving wheel 12 on the stepping motor 14 is rotationally connected with the driven wheel 17 on the rotating shaft 16 through the belt 15, and the rotating shaft 16 is arranged at the bottom of the air duct 1 through the bearing 13, and Gears 8 are installed at the left and right ends of the rotating shaft 16, four of which are fixed on the bearing 13 and the rotating shaft 16 respectively, the display 5 is arranged on the left side of the operation button 2, and the stepper motor 14 is arranged on the air duct 1 and At the junction of the fume hood 4, the gear 8 and the gear groove 10 are in a rolling connection.
