Description

Technical Field

[0001] The utility model relates to the technical field of oil fume purification equipment, in particular to an oil fume purification equipment for kitchens in the catering industry. Background Art

[0002] Kitchen fume is the smoke produced during the cooking process, which is mainly composed of oil, the smell of food and water vapor. In the kitchen, fume is a common phenomenon, especially in the process of high-temperature frying and stir-frying. The fume not only affects the air quality in the kitchen, but may also cause oil stains and corrosion on the surfaces of walls and ceilings due to long-term accumulation, and even affect human health. Therefore, in order to keep the kitchen air fresh and reduce the impact of fume on the environment and health, fume purification equipment is usually used to effectively remove the fume.

[0003] Range hoods are one of the commonly used kitchen fume purification equipment. They effectively remove the fume, odor and heat generated in the kitchen through the process of suction, filtration and exhaust, improve the kitchen air quality, and protect the environment and human health. Most of the existing range hoods filter and separate the fume through metal mesh filters, but the metal mesh filter alone has limited effect on fume separation, so that the exhausted fume still contains some grease, causing the fume to re-enter the environment, which may cause secondary pollution and even affect human health.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following is an explanation of the embodiments of the present utility model based on the overall structure of the present utility model.

[0022] Reference Figure 1 to Figure 2 In the embodiment of the utility model, a kitchen fume purification device for the catering industry includes: a shell 1, a metal mesh filter 2 is hinged on the side end of the shell 1, a water-cooled filter 3 is fixedly connected to the inner end of the shell 1, a smoke exhaust pipe 4 is connected to the top of the shell 1, a fan 5 is fixedly connected to the smoke exhaust pipe 4, and a waste oil collection tank 6 is plugged into the bottom end of the shell 1.

[0023] Reference Figure 6 The water-cooled filter 3 includes a cooling water tank 31, a water pumping pipe 32, a pump 33, a cooling water pipe 34 and a connecting pipe 35. The cooling water tank 31 is arranged at the side end of the shell 1 and is fixedly connected to the shell 1. The pump 33 is arranged at the top of the cooling water tank 31 and is fixedly connected to the cooling water tank 31. One end of the water pumping pipe 32 passes through the cooling water tank 31, and the other end of the water pumping pipe 32 is fixedly connected to the water inlet end of the pump 33. The cooling water pipe 34 is arranged at the upper end inside the shell 1 and is fixedly connected to the shell 1. One end of the cooling water pipe 34 passes through the shell 1 and is fixedly connected to the water outlet end of the pump 33. The other end of the cooling water pipe 34 passes through the shell 1 and is connected to the connecting pipe 35. The other end of the connecting pipe 35 is connected to the cooling water tank 31.

[0024] The above scheme is adopted: the cooling water in the cooling water tank 31 is pumped out by the pump 33 and circulated in the cooling water pipe 34, so that the oil smoke filtered by the metal mesh filter 2 contacts the outer side of the cooling water pipe 34, and the oil smoke is quickly cooled to liquefy the grease in it, and the oil smoke is filtered again, and the liquefied grease slides to the lowest point of the cooling water pipe 34 by gravity through the arc surface of the cooling water pipe 34 and drips, thereby preventing a large amount of grease from accumulating on the surface of the cooling water pipe 34 and affecting the cooling effect.

[0025] Reference Figure 3 to Figure 4 The metal mesh filter 2 includes a plate body 21, a filter hole 22, a fixed block 23, a rotating groove 24, a rotating connecting shaft 25 and a connecting block 26. The number of the rotating connecting shaft 25 is set in two groups, which are symmetrically distributed at the side end of the shell 1 and fixedly connected to the shell 1. The rotating groove 24 is set in two groups, which are symmetrically opened on both sides of the plate body 21. The plate body 21 is hinged to the shell 1 through the rotating groove 24 and the rotating connecting shaft 25. There are multiple groups of filter holes 22, which are evenly opened at one end of the plate body 21. Two groups of connecting blocks 26 are set, which are symmetrically distributed at the lower part of the side end of the shell 1 and fixedly connected to the shell 1. Two groups are set, which are symmetrically distributed at the lower inner end of the plate body 21 and fixedly connected to the plate body 21. The plate body 21 is clamped to the shell 1 through the fixed block 23 and the connecting block 26.

[0026] The above solution is adopted: the grease particles in the oil fume are blocked by the filter holes 22 on the metal mesh filter 2. These particles will be intercepted by the gaps between the meshes and cannot pass through the metal mesh, so they are trapped on the meshes to filter the oil fume.

[0027] Reference Figure 5 The fan 5 includes a casing 51, an air inlet 52, an air outlet 53, an impeller 54 and a motor 55. The casing 51 is arranged at the inner end of the smoke exhaust pipe 4 and is fixedly connected to the smoke exhaust pipe 4. The air inlet 52 is opened at the side end of the casing 51, and the air outlet 53 is opened at the top of the casing 51. The motor 55 is arranged at the side end of the casing 51 and is fixedly connected to the casing 51. The output end of the motor 55 passes through the casing 51 and is fixedly connected to the impeller 54. The impeller 54 is arranged at the inner end of the casing 51.

[0028] By adopting the above solution, the exhaust efficiency of the range hood can be increased through the operation of the fan 5, ensuring that more oil smoke and odor are effectively sucked in and exhausted, thereby improving the overall performance of the range hood.

[0029] The working principle of the utility model is as follows: when in use, the motor 55 is first started to draw the generated oil smoke from the metal mesh filter 2 into the housing 1, the oil smoke is preliminarily separated by the metal mesh filter 2, and then the pump 33 is started to circulate the cooling water in the cooling water pipe 34 to separate the oil smoke in the housing 1 again, and finally the oil smoke is discharged through the exhaust pipe 4 after two treatments; the cooling water in the cooling water tank 31 is drawn out by the pump 33 and circulated in the cooling water pipe 34, so that the oil smoke filtered by the metal mesh filter 2 contacts the outer side of the cooling water pipe 34, the oil smoke is quickly cooled, the grease in the oil smoke is liquefied, the oil smoke is filtered again, and the liquefied grease slides to the lowest point of the cooling water pipe 34 with gravity through the arc surface of the cooling water pipe 34 and drips, so as to prevent a large amount of grease from accumulating on the surface of the cooling water pipe 34 and affecting the cooling effect.

[0030] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
