Description

Oil drop separation wind wheel type range hood

technical field

The utility model relates to the field of kitchen equipment, in particular to a range hood. the

Background technique

The range hood is a kitchen appliance that purifies the kitchen environment. It is installed above the healthy and energy-saving range hood stove in the kitchen. It can quickly take away the waste burned by the stove and the oil fume harmful to the human body produced during the cooking process, and discharge it to the outside, reduce pollution, purify the air, and have anti-virus and explosion-proof safety guarantees. effect. Range hoods have not been in the kitchen of ordinary Chinese families for a long time. Early home kitchen smoke exhaust work was done by exhaust fans. Although the exhaust fan can get rid of most of the oily fumes in the kitchen, it is unable to solve the pollution of the entire kitchen by the oily fumes generated during cooking. The cooking fume contains many substances harmful to the human body. If people work in a room full of fumes for a long time, it will cause many diseases. the

For the Chinese, the dietary structure of Chinese people is different from that of Westerners, so the variety, style and arrangement of kitchen utensils in the kitchen are very different from those of Western countries. In Chinese food processing, frying, frying, cooking , frying occupies a large proportion, resulting in a lot of oil fume in the Chinese kitchen, and it is easy to make the kitchen environment greasy and difficult to clean. Therefore, the range hood has become a "powerful weapon" to change the kitchen environment. It changes the kitchen environment and reduces the damage caused by oil fume to the kitchen environment and human health. Range hood can be described as the "killer" of oil fume. the

The oil fume of the existing range hood is directly discharged into the atmosphere by the flue through the exhaust pipe after being inhaled by the wind wheel, and this type of range hood cannot be used in some places where environmental protection is required. the

Contents of the invention

The technical problem to be solved by the utility model is to provide an oil drop separation wind wheel type range hood, the range hood adds diffuse flow bumps on the surface of the wind wheel blades, so that the oil droplets can be separated more easily, and the To the effect of environmental protection. the

The utility model is achieved in the following way: an oil drop separation wind wheel type range hood, including a casing, a filter screen, an oil cup, an air extraction system and a smoke exhaust pipe, a suction port is arranged in the center of the bottom of the casing, The exhaust system is installed in the casing corresponding to the position of the suction port, the smoke exhaust pipe is installed on the top of the casing, the filter is covered on the suction port of the casing, and the oil cup is installed on the filter At the center of the bottom, the air extraction system communicates with the air inlet of the smoke exhaust pipe, and the blades of the wind wheel in the air extraction system are arranged with a number of diffuse flow protrusions. the

The air extraction system includes a wind guide ring, a wind wheel, a motor and a flue; the flue is fixedly installed on the casing, the outlet of the flue communicates with the air inlet of the exhaust pipe, and the motor is fixedly installed On the flue, the wind wheel is fixedly installed on the output shaft of the motor, the wind guiding ring is arranged between the filter screen and the wind wheel, and the scattered flow protrusions are scattered on the blades of the wind wheel. the

The wind wheel is a dry wing turbine. the

An operation panel is arranged on the casing. the

The bottom of the casing is provided with an illuminating lamp. the

The lighting lamp is an LED lamp group, and the lighting lamp is covered with a transparent shield. the

The oil drop separation wind wheel type range hood of the utility model adds diffuse flow bumps on the surface of the wind rotor blades, and the diffuse flow bumps increase the contact area between the oily fume and the wind wheel, and the oily fume flows on the diffuse flow bumps. The turbulence generated nearby makes it easier for oil droplets to be separated, reducing the content of oily fume in the final exhaust gas of the exhaust pipe, and playing an environmental protection role. the

Detailed ways

Below in conjunction with specific embodiment, further set forth the utility model. It should be understood that these embodiments are only used to illustrate the present utility model and are not intended to limit the scope of the present utility model. In addition, it should be understood that after reading the content of the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the appended claims of the application. the

Example 1

As shown in Figure 1, an oil droplet separation wind wheel type range hood includes a casing 1, a filter screen 2, an oil cup 3, an air extraction system and a smoke exhaust pipe 7, and a bottom center of the casing 1 is provided with a suction port, the exhaust system is installed in the position corresponding to the suction port in the casing 1, the smoke exhaust pipe 7 is installed on the top of the casing 1, the filter screen 2 is covered on the suction port of the casing 1, The oil cup 3 is installed at the center of the bottom of the filter screen 2, and the air extraction system communicates with the air inlet of the smoke exhaust pipe 7, and the blades of the wind wheel 52 in the air extraction system are arranged with a number of diffuse flow protrusions. the

As shown in Figure 2, the air extraction system includes a wind guiding ring 51, a wind wheel 52, a motor 53 and a flue 54; the flue 54 is fixedly installed on the casing 1, and the outlet of the flue 54 is connected The air inlet of the pipe 7 is connected, the motor 53 is fixedly installed on the flue 54, the wind wheel 52 is fixedly installed on the output shaft of the motor 53, and the wind guide ring 51 is arranged between the filter screen 2 and the wind wheel 52 During this period, the diffused flow protruding points are scattered on the blades of the wind wheel 52 . the
