Description

Technical Field

[0001] The invention relates to the technical field of range hoods, and in particular to an impeller assembly of a range hood. Background Art

[0002] The impeller of the range hood is an important component of the range hood. It is located on the top of the range hood and is responsible for absorbing the oil smoke, soot and odor generated during the cooking process. The impeller is usually made of metal material and has multiple blades. It generates a strong airflow through rotation, sucking pollutants such as oil smoke into the interior of the range hood, and then discharging them to the outside through the exhaust duct.

[0003] In the prior art, for example, a Chinese patent number: CN 207906148 U discloses an impeller for a range hood with an automatic cleaning function, which is provided with an upper ring, blades and a base, wherein the blades are fixed between the upper ring and the base; the blades are provided with upper and lower symmetrical protective layers, insulating layers and non-metallic electric heating coatings in sequence from the outside to the inside, the upper protective layer is hot-pressed and bonded to the upper insulating layer, the lower protective layer is hot-pressed and bonded to the lower insulating layer, and the non-metallic electric heating coating is coated on the inner side of the adjacent insulating layer; a positive conductive sheet and a negative conductive sheet are provided between the upper and lower layers of the non-metallic electric heating coating, the positive conductive sheets of adjacent blades are connected and finally connected to a power supply fixed on the range hood through a conductive slip ring, and the negative conductive sheets of adjacent blades are connected and finally connected to the power supply through a conductive slip ring. The utility model can be widely used in range hoods.

[0004] Existing range hood impellers, when in use, oil will remain on the surface of the impeller blades and be dried by air.

At the same time, the liquid extraction pump and the atomizing nozzle can be operated. The liquid extraction pump can extract the degreaser stored in the liquid storage tank to the connecting block position. The atomizing nozzle can be started to spray the degreaser evenly on the surface of each blade. After the degreaser is sprayed on the surface of the blade, the degreaser reacts with the oil stains adhered to the surface of the blades to decompose the oil stains, thereby making thicker oil stains fall off and dissolve. Combined with the heating wire heating the blades, the thicker oil stains adhered to the surface of the blades can fall off and dissolve, thereby improving the cleaning effect of the blades.

[0019] 2. When the self-cleaning range hood impeller is not working normally, the electric telescopic rod is in an extended state, and the ring and rubber pad are placed on the outside of the atomizing nozzle. This can prevent oil from entering the atomizing nozzle and causing blockage when the range hood impeller is running, avoid affecting the spraying and degreasing cleaning work of the atomizing nozzle, and increase the service life of the atomizing nozzle.

[0020] 3. When installing and using the range hood impeller, align the blade with the installation hole and insert it. Screw in the third nut from the bottom of the inner plate to clamp and fix the blade. Through the coordinated use of the limit hole and the limit rod, the blade drives the limit rod to be inserted into the limit hole. This can ensure that the installation angles of multiple blades remain consistent, thereby improving the convenience of blade installation operation. The impeller can install and disassemble the blades individually, making it convenient to replace a single damaged blade, effectively reducing the maintenance cost of the impeller.

Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 8The present invention provides a technical solution: an impeller assembly of a range hood, comprising: an inner disk 1, a plurality of blades 2 and an outer disk 3, a plurality of mounting holes 11 are evenly opened on the upper surface of the inner disk 1, a mounting plug rod 13 is fixedly connected to the lower surface of the blade 2, a plurality of slots 15 are evenly opened on the lower surface of the outer disk 3, a plug block 16 is arranged inside the slot 15, a connecting piece 17 is fixedly connected to the lower surface of the plug block 16, and heating wires 18 are arranged on the outer surfaces of both sides of the connecting piece 17; a spray assembly 4, the spray assembly 4 is fixedly connected to the upper surface of the inner disk 1, the spray assembly 4 includes a plurality of positioning rods 401, the outer surfaces of the plurality of positioning rods 401 are all provided with fixing seats 404, and the outer surfaces of the plurality of fixing seats 404 are fixedly connected with connecting wires 18.

After the blades 2 and the inner disk 1 are installed, the slots 15 and the plug blocks 16 are matched to assist in the installation of the outer disk 3. After the connecting pieces 17 are inserted into the interior of the plurality of blades 2 in turn, the outer disk 3 is spliced ​​with the inner disk 1 so that the slots 15 are aligned with the plurality of plug blocks 16 respectively, so as to ensure the accuracy of the installation position of the outer disk 3 and limit the position of the outer disk 3 at the same time.

[0033] like Figure 1-Figure 3 As shown, the number of mounting holes 11 and blades 2 is equal, and the outer surface of the mounting plug rod 13 is threadedly connected with a third nut, and two groups of limiting holes 12 are opened on the upper surface of the inner disk 1 near the mounting holes 11, and the lower surface of the blade 2 is symmetrically fixedly connected with the limiting rod 14, and the limiting rod 14 cooperates with the position of the limiting hole 12. When installing the blade 2, the blade 2 is inserted into the position of the mounting hole 11, and the blade 2 can be clamped and fixed by screwing in the third nut from the bottom position of the inner disk 1. The impeller can install and disassemble the blade 2 separately, which is convenient for replacing a single damaged blade 2, effectively reducing the maintenance cost of the impeller, and when the blade 2 is installed, the limiting rod 14 is inserted into the limiting hole 12, which can play a role in auxiliary positioning of the installation angle of the blade 2, thereby ensuring that the installation angles of multiple blades 2 are consistent, thereby improving the convenience of the installation operation of the blade 2.

When the impeller is self-cleaning, since the connecting piece 17 is inserted into the blade 2, the heating wire 18 can heat the surface of the blade 2 when it is running, so that the oil stains adhered to the surface of the blade 2 are melted by the heat. At this time, starting the range hood to drive the impeller to rotate at a high speed can throw out the oil stains, thereby completing the self-cleaning of the impeller of the range hood.

[0035] like Figure 3 As shown, a shaft sleeve 8 is fixedly connected to the upper surface of the inner disk 1, a driving shaft 9 is arranged on the inner surface of the shaft sleeve 8, and a fixing cover 10 is threadedly connected to the outer surface of the driving shaft 9 near the upper end surface. When installing the impeller of the range hood, the fixing groove at the bottom of the inner disk 1 is aligned with the installation position of the driving motor and inserted, and the fixing cover 10 is screwed to complete the fixed installation of the impeller. The driving motor drives the driving shaft 9 to rotate, which can drive the impeller to rotate at high speed.

[0036] like Figure 5 As shown, a plurality of mounting rods 6 are evenly and fixedly connected to the upper surface of the inner disk 1, and the outer surface of the mounting rod 6 slides through the outer disk 3. The outer surface of the mounting rod 6 is threadedly connected with a second nut 7, and the second nut 7 is located on the upper side of the outer disk 3. When the outer disk 3 is inserted into the position of the plug block 16 and the connection with the inner disk 1 is completed, the second nut 7 is loosened and taken out. After the outer disk 3 is inserted into the outer side of the mounting rod 6, the second nut 7 is screwed on to complete the fixed installation of the outer disk 3. After the inner disk 1 and the outer disk 3 are installed, the plurality of blades 2 can be firmly installed between the inner disk 1 and the outer disk 3.

[0037] like Figure 6 and Figure 7 As shown, a fixing plate 402 is fixedly connected to the outer surface of the positioning rod 401, and a first nut 403 is threadedly connected to the outer surface of the positioning rod 401 near the upper position of the fixing plate 402, and the fixing seat 404 is located between the fixing plate 402 and the first nut 403. When installing the connecting block 405, after loosening and removing the first nut 403, the fixing seat 404 drives the connecting block 405 to be inserted into the outer position of the positioning rod 401. The setting of the fixing plate 402 can provide support for the bottom of the fixing seat 404, and then the first nut 403 is screwed on, so that the fixing seat 404 can be clamped and fixed at the upper side position of the fixing plate 402, thereby completing the fixed installation of the connecting block 405.

[0038] like Figure 1 , Figure 6 and Figure 7As shown, the atomizing nozzle 406 is located in the middle of the blade 2, the outer surface of the connecting block 405 is fixedly connected with a connecting pipe 407, the end face of the connecting pipe 407 is fixedly connected with a liquid pump 408, the liquid pump 408 is connected with the connecting block 405, the input end of the liquid pump 408 is fixedly connected with a connecting pipe 409, the end face of the connecting pipe 409 is fixedly connected with a liquid storage tank 410, the liquid storage tank 410 is connected with the liquid pump 408, when the heating wire 18 is running to heat and melt the oil stains on the blade 2, by injecting liquid into the liquid storage tank 410 before installing the impeller of the range hood Degreaser, when the impeller of the range hood is self-cleaning, start the liquid extraction pump 408. The operation of the liquid extraction pump 408 can extract the degreaser from the liquid storage tank 410 through the connection of the connecting pipe 409. Then, the operation of the liquid extraction pump 408 can inject the degreaser into the connecting block 405 through the connecting pipe 407. At this time, start the atomizing nozzle 406 to evenly spray the degreaser on the surface of each blade 2. Combined with the heating of the blade 2 by the heating wire 18, the thicker oil stains adhering to the surface of the blade 2 can fall off and dissolve, thereby improving the cleaning effect of the blade 2.

[0039] like Figure 6 and Figure 7 As shown, a filling port 411 is provided on the upper surface of the liquid storage tank 410, and a sealing cover 412 is threadedly connected to the outer surface of the filling port 411, a fixing sleeve 413 is fixedly connected to the outer surface of the liquid storage tank 410, and a plurality of supporting legs 414 are evenly fixedly connected to the outer surface of the fixing sleeve 413, and the supporting legs 414 are fixedly connected to the connecting block 405. When the impeller of the range hood is maintained and degreaser is added, the sealing cover 412 is twisted and taken out, and the liquid storage tank 410 can be added from the position of the filling port 411. Through the coordinated arrangement of the fixing sleeve 413 and the supporting legs 414, the liquid storage tank 410 and the connecting block 405 can be hard-connected, which plays a role in reinforcing and supporting the position of the liquid storage tank 410 and improves the stability of the overall structure.

[0040] like Figure 1 and Figure 8As shown, an electric telescopic rod 503 is fixedly connected between the first support block 501 and the second support block 502, and a collar 504 is fixedly connected between the upper surfaces of the two second support blocks 502. A rubber pad 505 is arranged on the inner surface of the collar 504. The collar 504 is at the same height as the atomizing nozzle 406, and the inner surface of the rubber pad 505 fits the outer surface of the atomizing nozzle 406. When the self-cleaning range hood impeller is not working normally, the electric telescopic rod 503 is in an extended state, and the electric telescopic rod 503 can drive the collar 504 to be at the outer side of the atomizing nozzle 406. The rubber pad 505 can fill the gap between the collar 504 and the atomizing nozzle 406, thereby strengthening the sealing effect, thereby preventing oil from entering the atomizing nozzle 406 and causing blockage when the range hood impeller is running, avoiding affecting the operation of the atomizing nozzle 406 for spraying and degreasing cleaning, and improving the service life of the atomizing nozzle 406.

[0041] like Figure 1 and Figure 8 As shown, a telescopic sleeve 506 is fixedly connected between the first support block 501 and the second support block 502, and the telescopic sleeve 506 is sleeved on the outer surface of the electric telescopic rod 503. When the range hood impeller is self-cleaning, the electric telescopic rod 503 starts to contract and can drive the ring 504 to move downward, so that the atomizing nozzle 406 is directly exposed to the outside, and self-cleaning can be performed. When the electric telescopic rod 503 drives the ring 504 to move up and down, the telescopic sleeve 506 will follow the telescopic deformation. By arranging the telescopic sleeve 506 on the outside of the electric telescopic rod 503, the electric telescopic rod 503 can be protected to avoid oil infiltration when the range hood impeller is running, thereby preventing the electric telescopic rod 503 from being damaged, thereby improving the service life of the electric telescopic rod 503.

[0042] The use method and working principle of the device: when installing and using the range hood impeller, align the blade 2 with the mounting hole 11 and insert it. Screw in the third nut from the bottom of the inner plate 1 to clamp and fix the blade 2. The impeller can install and disassemble the blade 2 separately, which is convenient for replacing a single damaged blade 2, effectively reducing the maintenance cost of the impeller. When the blade 2 is installed, the limiting hole 12 and the limiting rod 14 are used in conjunction with the blade 2 to drive the limiting rod 14 to be inserted into the limiting hole 12, so that the installation angles of multiple blades 2 are kept consistent, which improves the convenience of the installation operation of the blade 2. Then, the plug block 16 is taken out to drive the connecting piece 17 to follow the After the outer disk 3 is inserted into the inner disk 1, the outer disk 3 is spliced ​​with the inner disk 1 so that the slots 15 are aligned with the plurality of plug-in blocks 16 respectively, so as to ensure the accuracy of the installation position of the outer disk 3. After the outer disk 3 is inserted into the outer position of the installation rod 6, the second nut 7 is screwed on to complete the fixed installation of the outer disk 3. After the inner disk 1 and the outer disk 3 are installed, the plurality of blades 2 can be firmly installed between the inner disk 1 and the outer disk 3. When the surface of the blade 2 adheres to oil and dirt after the impeller of the range hood has been used for a long time and affects the use, the heating wire 18 can be operated to heat the surface of the blade 2 so that the oil and dirt adhered to the surface of the blade 2 are melted by the heat. At this time, the range hood is started to drive the impeller to rotate at a high speed to throw out the oil and dirt. The self-cleaning work of the impeller of the range hood is completed. When the heating wire 18 is running, the liquid extraction pump 408 and the atomizing nozzle 406 are started. The liquid extraction pump 408 can extract the degreasing agent stored in the liquid storage tank 410 to the position of the connecting block 405. The atomizing nozzle 406 can be started to spray the degreasing agent evenly on the surface of each blade 2. The heating wire 18 heats the blade 2, which can make the thicker oil stains adhering to the surface of the blade 2 fall off and dissolve, thereby improving the cleaning effect of the blade 2. The fixed sleeve 413 and the support leg 414 are arranged in coordination to reinforce and support the position of the liquid storage tank 410, thereby improving the stability of the overall structure. When the self-cleaning range hood impeller is working normally, the electric telescopic rod 503 is in an extended state, and the ring 504 and the rubber pad 505 are sleeved on the outer side of the atomizing nozzle 406 to prevent oil from entering the atomizing nozzle 406 and causing blockage when the range hood impeller is running, thereby avoiding affecting the operation of the atomizing nozzle 406 for spraying and degreasing cleaning, thereby improving the service life of the atomizing nozzle 406. By arranging the telescopic sleeve 506 on the outer side of the electric telescopic rod 503, the electric telescopic rod 503 can be protected to avoid oil from entering when the range hood impeller is running and causing damage to the electric telescopic rod 503, thereby improving the service life of the electric telescopic rod 503.

[0043] The wiring diagram of the atomizing nozzle 406, the liquid extraction pump 408, the electric telescopic rod 503 and the heating wire 18 in the present invention is common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use, so the control method and wiring layout of the atomizing nozzle 406, the liquid extraction pump 408, the electric telescopic rod 503 and the heating wire 18 will not be explained in detail.
