Description

a range hood

technical field

The utility model relates to equipment used in the catering industry, 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 outside, reduce pollution, purify the air, and have anti-virus and explosion-proof safety guarantees. effect. the

Range hoods have become indispensable kitchen equipment for modern families and catering industries. Early kitchen exhaust work was done by exhaust fans. Although the exhaust fan can get rid of most of the fume in the kitchen, it is unable to solve the pollution of the cooking fume to the entire kitchen and the back hall. 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

Utility model content

The purpose of the utility model is to provide a range hood with simple structure, good smoking effect and lower noise. the

The scheme of the utility model is as follows: a range hood, including a hood and a centrifugal fan, is characterized in that an oblique smoke inlet is provided under the hood, and an oil grate is arranged at the smoke inlet. The centrifugal fan is located in the upper middle part of the hood, and a smoke outlet is provided above the centrifugal fan or behind the middle part of the hood, and the left and right sides, the bottom and the front of the centrifugal fan are closed and the left and right sides and the bottom are provided with a smoke outlet. There is a muffler plate, a smoke return port is provided in front of the centrifugal fan, and at least two oil fume filter cartridges or filters are provided on both sides of the smoke return port; the bottom of the hood and the surrounding frames on the four sides are provided with oil tank. the

The oil filter grid is a cube composed of two layers of stainless steel plates. Both sides of the oil filter grid are provided with vertically arranged smoke inlet holes of the same size, and the smoke inlet holes on both sides are evenly staggered in the vertical direction. Arranged, oil outlet holes are provided on both sides of the oil filter grid. the

The filter cylinder is composed of a steel mesh cylinder and polymer filter cotton, the polymer filter cotton surrounds the inner side of the steel mesh cylinder, and one end of the steel mesh cylinder is closed. the

The oil groove at the bottom of the hood is also provided with at least one oil outlet. the

An oil collecting box is arranged below the oil outlet. the

The advantages of this new implementation:

1. The traditional oil fume purification and separation equipment is integrated into one overall equipment, which occupies a small space and is easy to install. the

2. An oil filter grid is installed when the oil fume enters, which has a better oil discharge effect and can prevent the fire generated during cooking from entering the hood, avoiding fire hazards. the

3. The sound-absorbing panels are installed on the two sides of the centrifugal fan, which can effectively reduce the noise generated by the centrifugal fan when it is working. the

4. The utility model can customize range hoods of various specifications according to customer needs. When there are multiple range hoods in the back hall of the restaurant, they can work independently of each other. the

5. The utility model integrates the fan and the purification equipment in the machine cover, which has high working efficiency and saves electricity cost at the same time. the

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described. the

A range hood, comprising a hood 1 and a centrifugal fan 2, an oblique smoke inlet 3 is provided under the hood 1, and an oil grating 4 is arranged at the smoke inlet 3; The centrifugal fan 2 is located at the upper middle part of the hood 1, and a smoke outlet 5 is provided above the centrifugal fan 2 or behind the middle part of the hood, and the left and right sides, the lower part and the front of the centrifugal fan 2 are closed and are provided with A muffler plate 6, a smoke return port 7 is provided in front of the centrifugal fan 2, and at least two oil fume filter cartridges 8 or filters are arranged on both sides of the smoke return port 7; Frame is provided with oil groove 9. the

The oil filter grid 4 is a cube made of two layers of stainless steel plates. Both sides of the oil filter grid 4 are provided with vertically arranged smoke inlet holes 10 of the same size, and the smoke inlet holes 10 on both sides are arranged vertically. Evenly staggered and arranged in the direction, and oil outlet holes are arranged on both sides of the oil filter grid 4 . the

The filter cartridge is composed of a steel mesh cylinder 8 and a polymer filter cotton 11, the polymer filter cotton 11 surrounds the inner side of the steel mesh cylinder 8, and one end of the steel mesh cylinder 8 is closed. the

The oil groove 9 at the bottom of the hood is also provided with at least one oil outlet, and an oil collecting box is arranged below the oil outlet. the

When the utility model is implemented, the centrifugal fan 2 works, and the oil fume enters the hood from the smoke inlet 3. Since the smoke inlet holes 10 of the oil grate 4 on the smoke inlet 3 are vertically staggered, the oil fume is blocked when it enters. Part of the oil fume condenses into oil droplets and flows along the inclined inner wall of the oil filter grid to the lower end of the oil filter grid and flows to the bottom of the hood 1 through the set oil outlet, and finally flows out through the oil outlet set at the bottom of the hood 1; A part of oil fume enters the filter cartridge 8, flows out after being filtered by the polymer filter cotton 11, enters the centrifugal fan chamber through the smoke return port 7 provided in front of the centrifugal fan 2, and is finally discharged out of the smoke port 5. Simultaneously, part of the fumes entering the hood 1 can also slide down to the oil groove at the bottom of the hood along the oil grooves 12 arranged on the four sides of the hood 1 after being condensed into oil droplets, and discharged through the oil outlet. the

The polymer filter cotton 11 in the utility model can be replaced at any time as required and has low cost. the

The noise reduction plate 6 in the utility model can effectively reduce the noise generated when the centrifugal fan works. the

Although the specific embodiments of the present invention have been described and illustrated in detail above, it should be noted that we can carry out various equivalent changes and modifications to the above-mentioned embodiments according to the concept of the present invention, and the functional effects produced by it If it still does not exceed the spirit covered by the specification and drawings, it should be within the protection scope of the present utility model. the
