Description

Technical Field

[0001] This utility model relates to the field of oil fume purification, and in particular to an oil fume purification device with indoor circulation function. Background Technology

[0002] When oil is heated above 200°C, it produces acrolein, the main component of cooking fumes. Acrolein has a strong pungent odor and is highly irritating to the mucous membranes of the nose, eyes, and throat, which can cause respiratory diseases such as rhinitis, pharyngitis, and bronchitis. When oil is heated to the point of "flaming," the temperature exceeds 300°C. At this point, in addition to acrolein, condensates are also produced, leading to chronic poisoning and easily inducing respiratory and digestive system cancers. Therefore, the purification of cooking fumes is of great importance.

[0003] Most current fume purification equipment requires ductwork to extract and process the fumes before discharging them outdoors. This necessitates ductwork installation, increasing the size and manufacturing costs of the range hood. In the authorized Chinese utility model patent "Announcement No.: CN216281594U, Title: An Indoor Circulating Fume Hood Type Fume Purifier," a method is used to better purify toxic substances in the fumes through a sequence of elements from left to right: an ionizer, a collector, a first filter, a UV lamp, a second filter, a third filter, a filter screen, and a vortex filter. However, the aforementioned application features numerous and loosely arranged filter structures, resulting in a large size of the fume purification equipment, requiring significant installation space, and the need for multiple filtration layers, leading to lower fume treatment and filtration efficiency.

[0066] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0067] Figures 1 to 11 The diagram shown is a structural schematic of an embodiment of the oil fume purification device with indoor circulation function of this utility model.

[0068] Example 1

[0069] The fume purification equipment with indoor circulation function includes a supporting outer shell 1.

[0070] The equipment support housing 1 includes a rectangular frame 101 and a triangular frame 102, with the triangular frame 102 connected to the lower side of the rectangular frame 101;

[0071] Oil separator 2, which is embedded in one side of the triangular frame shell 102;

[0072] Oil slinger 3, an oil slinger 3 is provided above the oil slinger 3, and the oil slinger 3 is connected to the inner wall of the triangular frame shell 102;

[0073] A filter grid 4 is disposed above the oil slinger 3 and is connected to the inner wall of the rectangular frame 101.

[0074] The first layer of primary filter screen 5 and the second layer of composite filter screen 6 are arranged above the first layer of primary filter screen 5. The first layer of primary filter screen 5 is arranged above the filter grid 4. Both the first layer of primary filter screen 5 and the second layer of composite filter screen 6 are installed on the inner wall of the rectangular frame 101.

[0075] A partition plate 7 is disposed above the second layer composite filter screen 6, which is connected to the inner wall of the rectangular frame shell 101.

[0076] Exhaust fan 8, which is connected to the top side of partition plate 7;

[0077] Top cover 9, which is detachably connected to the top side of rectangular frame 101.

[0078] The second layer of composite filter 6 is a HEPA / activated carbon composite filter.

[0079] In this technical solution, an internal circulation system is adopted. Indoor air is drawn into the equipment support shell 1 through the built-in exhaust fan 8. Inside the equipment support shell 1, the oil fumes undergo multiple purification steps using the filter grid 4, the first layer of primary filter 5, and the second layer of composite filter 6, which treats harmful particles, impurities, odors, and pollutants in the air, thereby improving indoor air quality. The entire equipment has a compact structure, occupies little space, and is easy to install in various indoor environments. At the same time, it has an aesthetically pleasing design that blends with interior decoration.

[0080] During use, under the action of the exhaust fan 8, indoor air enters the equipment support shell 1 through the oil separator 2 and the oil slinger 3, and then passes through the filter grid 4, the first layer of primary filter 5 and the second layer of composite filter 6 in sequence, and finally exits the equipment support shell 1 through the exhaust port 11, realizing indoor circulation.

[0081] When passing through the filter grid 4, the first layer of primary filter 5, and the second layer of composite filter 6, harmful particles and impurities in the fumes can be adsorbed, and the air can be deeply purified to remove odors and pollutants.

[0082] The top of the triangular frame shell 102 is connected to multiple lifting rings 10.

[0083] In this technical solution, the lifting ring 10 facilitates the installation of the equipment.

[0084] The top cover 9 has an exhaust vent 11.

[0085] In this technical solution, the air drawn in by the exhaust fan 8 can be discharged using the exhaust port 11.

[0086] A control panel 12 is provided on the front side of the triangular frame shell 102.

[0087] In this technical solution, the use of the purification equipment can be controlled by the control panel 12, and the operation of the equipment can be intelligently controlled.

[0088] An LED light 13 is provided on the side of the triangular frame shell 102 where the oil separator 2 is installed.

[0089] In this technical solution, LED lights 13 can be used to supplement the light blocked by the equipment support housing 1.

[0090] A power cord 14 is installed on the side of the rectangular frame 101, and the power cord 14 is electrically connected to the filter grid 4, the oil slinger 3, and the exhaust fan 8 respectively.

[0091] In this technical solution, a power supply can be connected using power cable 14.

[0092] Example 2

[0093] As an embodiment of this application, the difference between it and Embodiment 1 is that the first layer of primary filter screen 5 and the second layer of composite filter screen 6 are detachably connected to the inner side of the rectangular frame shell 101 through the disassembly assembly 15.

[0094] In this technical solution, the first primary filter 5 and the second composite filter 6 can be easily disassembled using the disassembly and assembly component 15.

[0095] The disassembly and assembly component 15 includes a mounting frame 1501. The inner walls of both sides of the rectangular frame shell 101 are connected to the mounting frame 1501. The inner wall of the mounting frame 1501 is connected to two vertically symmetrically distributed fixed shafts 1502.

[0096] Both sides of the first primary filter 5 and the second composite filter 6 are connected to connecting plates 1504. One side of the connecting plate 1504 is connected to a toothed collar 1503. The toothed collars 1503 at the first primary filter 5 and the second composite filter 6 are slidably sleeved on the surface of the fixed shaft 1502.

[0097] In this technical solution, the positions of the first primary filter 5 and the second composite filter 6 can be locked simultaneously using the disassembly and assembly component 15.

[0098] The inner wall of the mounting frame 1501 is rotatably connected to a rotating bar 1506. The upper and lower sides of the rotating bar 1506 are both in contact with anti-shaking toothed plates 1505. When the anti-shaking toothed plates 1505 are in contact with the toothed collar 1503, they engage.

[0099] The two anti-sway toothed plates 1505 are connected by elastic connectors 1507 distributed on the left and right.

[0100] In this technical solution, the first layer of primary filter screen 5 and the second layer of composite filter screen 6 can be locked by using the anti-sway toothed plate 1505 and toothed collar 1503.

[0101] One end of the rotating bar 1506 is rotatably connected to one side of the mounting frame 1501, and a rotating knob 1508 is connected to one end of the rotating bar 1506 extending out of the mounting frame 1501.

[0102] In this technical solution, the fixed shaft 1502 can be easily rotated by rotating the knob 1508.

[0103] In use, the toothed collar 1503 can be sleeved on the fixed shaft 1502 and the first layer of primary filter screen 5 or the second layer of composite filter screen 6 can be pushed inward, thereby driving the connecting plate 1504 and the toothed collar 1503 to slide, thereby installing the first layer of primary filter screen 5 and the second layer of composite filter screen 6 into the equipment support housing 1 in sequence.

[0104] Then, rotating the knob 1508 will drive the fixed shaft 1502 to rotate, which in turn drives the rotating bar 1506 to rotate. At this time, the anti-sway toothed plates 1505 on both sides can move in opposite directions, so that the anti-sway toothed plates 1505 and the toothed collar 1503 are engaged and locked, thereby locking the position of the toothed collar 1503. This will lock the position of the first primary filter 5 and the second composite filter 6, making the structure of the first primary filter 5 and the second composite filter 6 more stable.

[0105] During disassembly, the rotating bar 1506 is rotated in the opposite direction to move the anti-sway toothed plate 1505 away from the toothed collar 1503. At this time, under the action of the elastic connector 1507, the two anti-sway toothed plates 1505 move towards each other, moving away from the toothed collar 1503. The toothed collar 1503 can then be moved, allowing the first primary filter 5 and the second composite filter 6 to be removed. The first primary filter 5 and the second composite filter 6 can then be cleaned or replaced to ensure the oil fume purification effect of the purification equipment.

[0106] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
