Description

Technical Field

[0001] The present application relates to the technical field of smoke hoods, and in particular to an intelligent oil-variable frequency-converting environmentally friendly smoke hood. Background Art

[0002] A smoke hood is a smoke collection device installed above a cooking source to collect oil smoke, and is mainly used in hotels or home kitchens.

[0003] The hood generally contains a smoke collecting chamber and an exhaust chamber. In order to reduce the pollution of the smoke extracted by the hood to the exhaust pipe, a filter is installed between the smoke collecting chamber and the exhaust chamber to filter the smoke. However, after long-term use, a large amount of dirt will adhere to the filter, so the staff regularly uses a water washing nozzle to wash the filter.

[0004] When flushing the filter, in order to prevent water from falling onto the cooking equipment below during the flushing process, a layer of waterproof cloth is generally laid on the cooking equipment before flushing, and the flushing process is relatively troublesome. Summary of the invention

[0034] The present application is further described in detail below in conjunction with the accompanying drawings.

[0035] The present application embodiment discloses an intelligent oil variable frequency environmental protection fume hood. Figure 1 , 2 The intelligent oil variable frequency environmental protection fume hood comprises a fume hood body 1, which comprises a smoke collecting chamber 2, an exhaust chamber 3 and a filter assembly. An exhaust pipe 4 connected to the exhaust chamber 3 is arranged at the upper end of the fume hood body 1, and one end of the exhaust pipe 4 is connected to an exhaust device, so that the oil smoke entering the fume hood body 1 can be sucked into the exhaust chamber 3 and discharged through the exhaust pipe 4. The filter assembly is installed between the smoke collecting chamber 2 and the exhaust chamber 3. When the oil smoke enters the smoke collecting chamber 2, it enters the exhaust chamber 3 after being filtered by the filter assembly, and then is discharged through the exhaust pipe 4, reducing the adhesion of oil stains on the inner wall of the exhaust pipe 4.

[0036] Reference Figure 2 , 3 The filter assembly includes a filter cartridge 5, which is a cylindrical structure and has an axially penetrating cavity. The filter cartridge 5 is rotatably connected between the two inner walls of the smoke hood body 1 and is located between the smoke collecting chamber 2 and the exhaust chamber 3. The exhaust chamber 3 is located below the filter cartridge 5 and has a telescopic water receiving plate 6 extending horizontally.

[0037] Specifically, refer to Figure 2 The telescopic water receiving plate 6 includes an inner plate 7 connected to the inner wall of the exhaust chamber 3 and an outer plate 8 in which the inner plate 7 is mounted. The end of the outer plate 8 away from the inner plate 7 is integrally formed with a first partition 9. When the outer plate 8 is in a fully retracted state, the upper end of the first partition 9 is tangent to the lower end of the filter cartridge 5, and a water receiving trough for receiving liquid is formed between the first partition 9 and the telescopic water receiving plate 6. A second partition 10 extending downward is welded to the inner wall of the upper end of the hood body 1. The second partition 10 is tangent to the outer peripheral side of the upper end of the filter cartridge 5, so that the filter cartridge 5 rotates between the first partition 9 and the second partition 10, and the inhaled oil smoke can only pass through the filter cartridge 5 between the first partition 9 and the second partition 10.

[0038] Reference Figure 2The outer wall of the hood body 1 is connected to a drain pipe 11 connected to the water receiving trough, and the water falling into the water receiving trough can be discharged through the drain pipe 11. Furthermore, the telescopic water receiving plate 6 is arranged to be inclined upward, so that the water falling on the telescopic water receiving plate 6 can be gathered toward the direction of the drain pipe 11, so that the water falling into the water receiving trough can be discharged from the drain pipe 11.

[0039] Reference Figure 2 A fixing assembly for fixing the inner plate 7 and the outer plate 8 is provided between the inner plate 7 and the outer plate 8. The fixing assembly includes a fixing bolt 12, a slide groove 13 extending along the sliding direction of the outer plate 8 is provided on the lower end surface of the inner plate 7, and a threaded hole 14 is provided on the lower end surface of the outer plate 8 and at one end away from the first partition plate 9. The fixing bolt 12 is threadedly connected to the threaded hole 14, and one end of the fixing bolt 12 can be extended into the slide groove 13 with the help of the threaded hole 14, so that the fixing bolt 12 slides in the length direction of the slide groove 13. When the fixing bolt 12 abuts against the end of the slide groove 13 away from the smoke collecting chamber 2, the telescopic water receiving plate 6 is in a fully retracted state. When the fixing bolt 12 abuts against the end of the slide groove 13 close to the smoke collecting chamber 2, the telescopic water receiving plate 6 is in a fully extended state, so that the telescopic water receiving plate 6 can cover the bottom of the filter cartridge 5.

[0040] Reference Figure 2 , 3 , a cleaning assembly for cleaning the filter cartridge 5 is provided in the smoke hood body 1. Specifically, the cleaning assembly includes a main pipe 15 installed on the upper end wall of the exhaust chamber 3, the main pipe 15 extends along the axial direction of the filter cartridge 5, and one end of the main pipe 15 is connected to an external water pump or high-pressure flushing equipment so that high-pressure water can flow into the main pipe 15. The main pipe 15 is provided with a plurality of nozzles 16 arranged along the length direction of the main pipe 15. The nozzle 16 is connected to the main pipe 15, and the nozzle 16 is tilted toward the exhaust chamber 3 away from the smoke collecting chamber 2, so that the high-pressure water sprayed from the nozzle 16 can be tilted and sprayed on the filter cartridge 5, and the filter cartridge 5 will rotate under the action of the high-pressure water, so that the high-pressure water can clean the filter cartridge 5 as a whole.

[0041] Reference Figure 3 , 4 , circular grooves 25 for rotating and installing the filter cartridge 5 are provided on two opposite inner walls of the smoke hood body 1, and a connecting rod 17 coinciding with the axis of the circular groove 25 is provided between the two circular grooves 25, and the two ends of the connecting rod 17 are respectively fixedly connected to the middle of the groove bottom of the two circular grooves 25. The two ends of the connecting rod 17 are rotatably connected to the limiting rod 18 through bearings, and the limiting rod 18 is perpendicular to the axis of the connecting rod 17, and the filter cartridge 5 is installed between the two limiting rods 18. That is, the two axial ends of the filter cartridge 5 are respectively welded to the two limiting rods 18, so as to realize the rotating connection between the filter cartridge 5 and the connecting rod 17, and the axis of the filter cartridge 5 and the connecting rod 17 coincide.

[0042] Reference Figure 3 , 4 The cleaning assembly also includes an internal cleaning member, which can clean the inner wall of the filter cartridge 5. Specifically, the internal cleaning member includes a cleaning disc 19, a connecting rod 17 is located between two limit rods 18 and is fixedly mounted with a reciprocating screw 20, and the cleaning disc 19 is coaxially connected to the reciprocating screw 20. When the cleaning disc 19 rotates relative to the reciprocating screw 20, the cleaning disc 19 can reciprocate along the axis direction of the reciprocating screw 20. Cleaning bristles 21 are evenly distributed on the outer circumference of the cleaning disc 19, and the cleaning bristles 21 are in contact with the inner wall of the filter cartridge 5, so that the cleaning disc 19 can clean the inner wall of the filter cartridge 5 through the cleaning bristles 21 during the reciprocating movement.

[0043] Reference Figure 3 , 4 In order to realize the synchronous rotation of the cleaning disc 19 and the filter cartridge 5, a positioning rod 22 extending along the axis direction of the connecting rod 17 is connected between the two limiting rods 18. Two positioning rods 22 are provided, and the two positioning rods 22 are symmetrically arranged with the axis of the connecting rod 17 as the center. A positioning hole 23 for the positioning rod 22 to pass through is opened on the cleaning disc 19. The positioning rod 22 is inserted into the positioning hole 23, so that the cleaning disc 19 can rotate synchronously with the filter cartridge 5.

[0044] Reference Figure 5 In order to conveniently discharge the sewage from the cleaning process of the cleaning disc 19 outside the filter cartridge 5, a sewage hole 24 connected to the water receiving tank is opened at the bottom of the circular groove 25. After the sewage is discharged from both ends of the axial direction of the filter cartridge 5 under the action of the cleaning disc 19, it will fall into the sewage hole 24 and flow into the water receiving tank through the sewage hole 24.

[0045] The implementation principle of an intelligent oil variable frequency environmental protection fume hood in the embodiment of the present application is:

[0046] When cleaning the filter cartridge 5, the telescopic water receiving plate 6 is adjusted to a fully extended state and is locked and fixed by the fixing bolts 12. Then, the nozzle 16 on the main pipeline 15 is started to spray high-pressure water to the filter cartridge 5, so that the filter cartridge 5 rotates and drives the cleaning disc 19 to reciprocate along the axial direction of the reciprocating screw 20, thereby cleaning the inside and outside of the filter cartridge 5.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
