Description

Technical Field

[0001] This utility model relates to the field of exhaust hood technology, and in particular to an exhaust hood structure for kitchen equipment. Background Technology

[0002] As a place for food preparation, the kitchen generates a large amount of oily fumes during the food preparation process. The pervasive fumes can make it impossible for people to work normally in the kitchen. Therefore, kitchen exhaust hoods and other fume extraction devices are often installed in the food preparation area. A kitchen exhaust hood consists of two parts: the hood body and the cover. The hood body is composed of three planes, and the cover is composed of four planes (or baffles) forming a cone. The exhaust hood is used to remove kitchen fumes. However, when traditional exhaust hoods are used for long-term exhaust, the inner wall of the exhaust hood absorbs a lot of oily fume particles, so the exhaust hood needs to be disassembled for cleaning. At the same time, most of the directly emitted fumes are only simply filtered through a filter screen, which makes the fumes fail to meet emission standards, thus reducing the effectiveness of the exhaust hood.

[0019] This utility model has the following beneficial effects:

[0020] The treatment assembly allows wastewater to undergo three stages of filtration: passing through a fine filter screen, filter cotton, and a carbon layer. The wastewater then flows through multiple treatment holes in the treatment drawer into the bottom of the treatment tank for further filtration. The installation assembly enables a pump to draw wastewater from the water filtration inside the assembly housing via a first installation branch pipe. This wastewater then flows through a second installation branch pipe into the assembly housing, subsequently falling into the treatment drawer. The treatment assembly then performs three stages of filtration on the wastewater. Next, the first and second valves on the first and second installation branch pipes are closed, while the third and fourth valves on the third and fourth installation branch pipes are simultaneously activated. This allows filtered water drawn from the fourth installation branch pipe to enter the first installation branch pipe. Then, the waste liquid flows from the first installation branch pipe into the second installation branch pipe, then from the second installation branch pipe into the third installation branch pipe, and then from the third installation branch pipe into the assembly horizontal pipe. At the same time, the filtered waste liquid is discharged through multiple assembly nozzles on the assembly horizontal pipe, thereby further spraying and reducing dust from the water filter's oil fumes. The drive assembly allows the drive motor to rotate the drive rod and drive pulley, which in turn drives the assembly horizontal pipe on the assembly pulley to rotate via a belt. This causes the assembly horizontal pipe to also drive multiple assembly nozzles to swing, thereby adjusting and spraying the oil fumes from the water filter to reduce dust, ensuring thorough filtration of the oil fumes and meeting emission standards, thus improving the performance.

The end of the first mounting branch pipe 11 passes through the assembly housing 2 and extends into the assembly housing 2. The end of the second mounting branch pipe 12 passes through the treatment tank 8 and extends into the treatment tank 8. A first valve is connected to the side wall of the first mounting branch pipe 11, and a second valve is connected to the side wall of the second mounting branch pipe 12. A third mounting branch pipe 13 is fixedly connected to the side wall of the first mounting branch pipe 11. The end of the third mounting branch pipe 13 is rotatably connected to one end of the assembly horizontal pipe 15. A fourth mounting branch pipe 14 is fixedly connected to the side wall of the second mounting branch pipe 12. The end of the fourth mounting branch pipe 14 passes through the treatment tank 8 and extends into the treatment tank 8. A third valve is connected to the side wall of the third mounting branch pipe 13, and a fourth valve is connected to the side wall of the fourth mounting branch pipe 14. By installing the pump 10, the pump 10 drives the first mounting branch pipe 11 to draw the waste liquid from inside the assembly housing 2, so that the waste liquid is discharged into the treatment tank 8 through the second mounting branch pipe 12.

[0030] An assembly horizontal tube 15 is rotatably connected between the two sides of the inner wall of the assembly housing 2. Multiple assembly nozzles 16 are fixedly connected to the bottom of the assembly horizontal tube 15. One end of the assembly horizontal tube 15 passes through the assembly housing 2 and extends to the outside of the assembly housing 2. An assembly pulley 17 is fixedly sleeved on the outer wall of the assembly horizontal tube 15. A drive assembly component for adjusting the rotation of the assembly pulley 17 is connected to the surface of the assembly housing 2. The drive assembly includes a drive bracket 18 fixedly connected to the surface of the assembly housing 2. A drive motor 19 is fixedly connected to the surface of the drive bracket 18.

[0031] The surface of the treatment box 8 has a treatment port, and a treatment component is installed inside the treatment port. The treatment component includes a treatment drawer 22 that is slidably connected inside the treatment port. Multiple treatment holes are opened through the side wall of the treatment drawer 22. A fine filter screen 23 is fixedly connected between the two sides of the inner wall of the treatment drawer 22. A carbon layer 25 is connected to the bottom of the fine filter screen 23 through a filter cotton 24. The waste liquid is filtered in three stages through the fine filter screen 23, the filter cotton 24, and the carbon layer 25.

[0032] Working principle: When in use, first install the assembly channel 4 vertically to the external pipe. Then, the assembly housing 2 on the assembly channel 4 also drives the exhaust hood body 1 to be vertical. At the same time, start the exhaust fan 6 on the exhaust hood body 1 so that the oil fumes are discharged into the interior of the exhaust hood body 1 through the exhaust hood body 1. Then, start the assembly valves on multiple assembly branch pipes 3 so that the exhaust gas is filtered by water inside the assembly housing 2.

[0033] Next, the first valve on the first installation branch pipe 11 and the second valve on the second installation branch pipe 12 are used to start the installation pump 10. The installation pump 10 drives the first installation branch pipe 11 to extract the waste liquid from the water filter inside the assembly housing 2, so that the waste liquid is discharged into the assembly housing 2 through the second installation branch pipe 12. Then the waste liquid falls into the processing drawer 22. Then the waste liquid undergoes three-stage filtration through the processing fine filter screen 23, the processing filter cotton 24 and the processing carbon layer 25, so that the filtered waste liquid is discharged into the bottom of the processing tank 8 through multiple processing holes on the processing drawer 22.

[0034] Next, close the first and second valves on the first and second mounting branches 11 and 12 to prevent waste liquid inside the assembly housing 2 from entering the first mounting branch 11. Then, prevent the waste liquid from being discharged into the treatment tank 8 through the second mounting branch 12. At the same time, start the third and fourth valves on the third and fourth mounting branches 13 and 14 to allow the fourth mounting branch 14 to draw filtered water into the first mounting branch 11.

[0035] Then, the waste liquid is discharged from the first installation branch pipe 11 into the second installation branch pipe 12, then from the second installation branch pipe 12 into the third installation branch pipe 13, and then from the third installation branch pipe 13 into the assembly horizontal pipe 15. At the same time, the filtered waste liquid is discharged through multiple assembly nozzles 16 on the assembly horizontal pipe 15, thereby further spraying and dust suppression of the oil fumes filtered by the water filter.

[0036] Simultaneously, the drive motor 19 on the drive bracket 18 is started, which drives the drive rod 20 and the drive pulley 21 to rotate. Then, the drive pulley 21 drives the assembly horizontal tube 15 on the assembly pulley 17 to rotate via the belt, which in turn drives multiple assembly nozzles 16 to swing, thereby adjusting the spraying of oil fumes from the water filter to reduce dust and reduce oil fume particles that are not fully filtered. At the same time, the waste liquid is recycled and reused, and the oil fumes are continuously purified. Finally, the processing drawer 22 is pulled out as needed to clean the waste inside the processing drawer 22.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
