Technical Field

[0001] The utility model relates to the technical field of range hoods, and particularly relates to a high-efficiency integrated smoke hood and oil fume purification device. Background Art

[0002] Since the oil fume content in commercial catering waste gas is relatively large, it needs to be treated before being discharged. The existing integrated smoke hood and oil fume purification devices for the catering industry generally have a high-voltage electrostatic device. After removing the oil stains through the high-voltage electrostatic field, the oil fume is discharged. However, the existing commercial integrated smoke hood and oil fume purification devices usually only have one air inlet and one high-voltage electrostatic device. When the waste gas emission volume is large, the removal effect on the oil fume is incomplete and the efficiency is low. Moreover, the high-voltage electrostatic device of the existing integrated smoke hood and oil fume purification device is arranged in the shell of the range hood, and the high-voltage power supply is easily polluted by the oil fume, and it is very troublesome to clean, replace or repair. It can be seen that the existing technology still needs to be improved. Content of the Utility Model

[0003] In view of the deficiencies of the above-mentioned existing technology, the purpose of the utility model is to provide a high-efficiency integrated smoke hood and oil fume purification device, aiming to improve the oil removal effect of the range hood.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A high-efficiency integrated smoke hood and oil fume purification device includes a smoke collecting hood and a fan assembly arranged on the smoke collecting hood.

Purification units are arranged on both the left and right sides of the box body, and a double air flow channel can be formed to increase the air extraction volume; the purification unit includes a shell and a high-voltage electrostatic field, and the high-voltage electrostatic field is used to remove the oil fume.

[0006] In the high-efficiency integrated smoke hood and oil fume purification device, a uniform air distribution net is further arranged in the shell, and an external electric box is further arranged on the outer side of the shell. The external electric box is used to install a high-voltage power supply and control electrical components.

[0007] In the high-efficiency integrated smoke hood and oil fume purification device, the external electric box includes an electric box shell and an electric box door movably connected to the electric box shell, and the electric box shell is detachably connected to one side of the shell.

[0008] In the high-efficiency integrated smoke hood and oil fume purification device, heat dissipation holes are arranged on the side wall of the electric box shell.

[0009] In the high-efficiency integrated smoke hood and oil fume purification device, a control panel is further arranged on the smoke collecting hood, and the control panel is electrically connected to the centrifugal fan and the high-voltage power supply for supplying power to the high-voltage electric field.

[0010] In the described high-efficiency integrated oil fume purification equipment with a smoke hood, an inclined partition is provided at the hood opening of the smoke collecting hood.

Specific embodiments

[0018] The utility model provides a high-efficiency integrated oil fume purification equipment with a smoke hood. To make the purpose, technical solution and effects of the utility model clearer and more definite, the following further elaborates on the utility model with reference to the accompanying drawings and by way of examples. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0019] Please refer to Figures 1-4, the present utility model provides an efficient integrated oil fume purification device for a fume hood, which includes a smoke collecting hood 1, a fan assembly arranged on the smoke collecting hood 1, and two purification units 4 located on the left and right sides of the fan assembly; the fan assembly includes a box body 2 and a centrifugal fan 3 arranged inside the box body 2; the left and right sides of the box body 2 are not provided with side plates, so it is through from left to right. The box body 2 is also provided with an exhaust port 17, and this exhaust port 17 can be arranged on the top plate of the box body 2, or on the front side plate or the rear side plate, and can be specifically set according to the specific position of the exhaust duct, so it has good adaptability; two opposite air inlets are arranged along the axial direction of the centrifugal fan 3, and an air outlet is arranged in the radial direction. The two air inlets are respectively opposite to the left and right sides of the box body 2, and the air outlet is communicated with the exhaust port 17.

[0020] As Figure 2 shown, the two purification units 4 are respectively arranged on the left and right sides of the box body 2, and each includes a housing 5, a uniform air distribution net 6 arranged inside the housing 5, and a high-voltage electrostatic field 7. The side of the housing 5 facing the box body 2 is not provided with a side plate, and it is communicated with the box body 2. An air inlet is provided at one end of the bottom of the housing 5 away from the fan, and this air inlet is communicated with the smoke collecting hood 1. Therefore, an air flow channel of the smoke collecting hood 1 - housing 5 - box body 2 can be formed (as Figure 3 shown). Through the action of the centrifugal fan 3, the oil fume-containing waste gas can pass through the smoke collecting hood 1, the housing 5, and the box body 2, and finally be discharged from the exhaust port 17. And the uniform air distribution net 6, the high-voltage electrostatic field 7, and the centrifugal fan 3 are arranged in the air flow channel, and the high-voltage electrostatic field 7 is located upstream of the centrifugal fan 3. Therefore, when the oil fume-containing waste gas flows through the high-voltage electrostatic field 7, the oil fume will be removed by it, so that the discharged air meets the emission requirements. And, because purification units 4 are arranged on both sides of the centrifugal fan 3, a double air flow channel can be formed, so the treatment amount of the oil fume-containing air can be greatly increased and the oil fume purification effect can be improved.

[0021] In this embodiment, by adopting the centrifugal fan 3, it can have double air inlets, and two purification units 4 are set for the double air inlets, and there are two air inlets communicated with the smoke collecting hood 1, forming a double air flow channel. Therefore, the treatment amount of the oil fume-containing waste gas can be increased, and it has a better oil removal effect.

[0022] Since the high-voltage electrostatic field 7 is arranged in the air flow channel, in order to prevent the oil fume from adhering to the high-voltage power supply 9, in a preferred embodiment, as Figure 2 shown, an external electric box 8 is arranged on one side of the housing 5, and the high-voltage power supply 9 for supplying power to the high-voltage electric field and control electrical components are arranged in the external electric box 8. Since this external electric box 8 is independent of the air flow channel, the oil fume can be prevented from adhering to the high-voltage power supply 9, the high-voltage power supply 9 can be better protected, and the oil fume can be prevented from adhering to the high-voltage power supply 9, improving safety.

[0023] For the convenience of the maintenance and cleaning of the high-voltage power supply 9 and the high-voltage electrostatic field 7, the external electric box includes an electric box housing 10 and an electric box door 11 movably connected to the electric box housing 10. The electric box housing 10 is detachably connected to one side of the housing 5. For example, the electric box door 11 is connected to the electric box housing 10 through a hinge, and the electric box housing 10 is connected to the housing 5 through a pin shaft and locked by a buckle. Of course, the electric box housing 10 and the electric box door 11 are not limited to these connection methods and can also be other movable connection methods. Therefore, when it is necessary to repair the high-voltage power supply 9 or the high-voltage electrostatic field 7, opening the electric box door 11 can repair the high-voltage power supply 9, and disassembling the electric box housing 10 can repair the high-voltage electrostatic field 7, which is very convenient.

[0024] In one embodiment, in order to enable the high-voltage power supply 9 to dissipate heat better, heat dissipation holes 12 are further provided on the side wall of the electric box housing 10.

[0025] In one embodiment, as Figure 1 shown, a control panel 16 is provided on the smoke collecting hood 1, and the control panel 16 is electrically connected to the centrifugal fan 3 and the high-voltage power supply 9. As Figure 4 shown, an inclined partition 13 is provided at the hood opening of the smoke collecting hood 1. The partition 13 is detachably connected to the smoke collecting hood 1. An oil collecting groove 14 is further provided on the side wall of the smoke collecting hood 1. The oil collecting groove 14 is provided with an oil leakage hole 15, and the oil leakage hole 15 is provided with a switching valve and can lead out the oil through a connecting pipeline.

[0026] In summary, by providing double air inlets and two purification units 4, the present utility model can form a double air flow channel, thereby having a greater processing capacity for oil fume and a better oil removal effect, and can adapt to the purification treatment of high-capacity oil fume-containing waste gas in commercial kitchens; in addition, by arranging the high-voltage power supply 9 outside the air duct, oil fume can be prevented from adhering to the surface of the high-voltage power supply 9, so it is safer.
