Description

Technical Field

[0001] This application relates to the field of range hood technology, and more specifically to an intelligent and energy-saving oil fume purification system. Background Technology

[0002] A range hood is an appliance installed above a kitchen stove. It is mainly used to collect, filter, and exhaust the fumes, steam, odors, and heat generated during cooking to improve kitchen air quality, protect human health, and reduce the pollution of the kitchen environment by oil stains.

[0003] Patent document (CN220969480U) discloses a range hood with an internal electric field for oil separation. However, after prolonged use, oil can solidify within the electric field, affecting its separation efficiency. In the aforementioned embodiment, an electric field cleaning device is used, where a sliding nozzle assembly sprays water horizontally above the electric field to clean it. However, due to the conductivity of water, excessive moisture can form a film on the electrodes and dust collection plate within the electric field. This film can conduct current, weakening the electric field's effectiveness in charging and adsorbing oil particles, thus reducing its purification efficiency. Furthermore, excessive moisture accumulation can cause short circuits, requiring a high level of waterproofing for the electric field and resulting in high costs.

[0004] Therefore, there is a need for an intelligent and energy-saving fume purification system that can clean oil stains in the electric field and adjust energy consumption when the purification capacity of the electric field decreases. Summary of the Invention

[0040] An illustrative example of an intelligent and energy-saving oil fume purification system, for reference. Figures 1 to 13 According to a preferred embodiment of the present invention, an intelligent and energy-saving oil fume purification system includes a housing 10, an oil filter plate 20, an oil separation and air distribution network 30, an electric field 40, and a fan 50.

[0041] Specifically, such as Figures 1 to 5 As shown, the housing 10 has an upper housing 101 and a lower housing 102. The lower housing 102 has a smoke inlet 1021 and a smoke filter chamber 1022. The upper housing 101 has a transition channel 1011, a purification chamber 1012, and a fan chamber 1013. The two ends of the transition channel 1011 are respectively connected to one end of the smoke filter chamber 1022 and the purification chamber 1012. The fan chamber 1013 is connected to one end of the purification chamber 1012 away from the transition channel 1011. The bottom of the lower housing 102 has an oil collection groove 1023. In addition, the oil filter plate 20 is arranged at an angle and separates the smoke inlet 1021 and the smoke filter chamber 1022. The lowest point of the oil filter plate 20 extends to the oil collection groove. The top opening of the trough 1023; in addition, the oil-separating and air-distributing mesh 30 is located at one end of the purification chamber 1012 near the fan chamber 1013; in addition, both electric fields 40 are located in the purification chamber 1012 and at one end of the oil-separating and air-distributing mesh 30 away from the transition channel 1011, and each electric field 40 has a heating wire; in addition, the fan 50 is located in the fan chamber 1013; in addition, the housing 10 has an operation panel with a cleaning button. After pressing the cleaning button, the heating wire is energized or de-energized; in addition, the intelligent energy-saving oil fume purification system also includes an oil channel, the two ends of which are connected to the electric field 40 and the oil collection trough 1023 respectively.

[0042] It should be noted that when the fan 50 is working, external oily fumes flow in from the smoke inlet 1021 of the lower housing 102 and pass through the oil filter plate 20. By setting the oil filter plate 20, most of the oil in the external oily fumes is filtered, and the filtered oil flows into the oil collection tank 1023 along the inclined oil filter plate 20. The oily fumes, having had most of the oil filtered, enter the oil filter chamber after passing through the oil filter plate 20, then flow in from the transition channel 1011 and pass through the oil-separating and equalizing air mesh 30. The oil-separating and equalizing air mesh 30 disperses the oily fumes into multiple streams, lowers the temperature of the oily fumes, and causes some of the oil in the oily fumes to condense into oil droplets. Subsequently, after passing through the oil-separating and equalizing air mesh 30, the oily fumes are purified by the electric field 40, further purifying the oily fume particles in the oily fumes. Finally, the oily fumes pass through the fan 50... The exhaust fan 50 is discharged to the outside. In this application, there are two electric fields 40, and multiple electric fields 40 can be set according to the degree of oil fume in the actual application environment. It should be noted that after long-term use, oil stains will accumulate and solidify in the electric fields 40, affecting the oil stain separation effect of the electric fields 40. In view of this, in this application, by setting the heating wire on the electric field 40, when the user feels that the smoke extraction capacity of the intelligent energy-saving oil fume purification system has decreased, he / she can press the cleaning button. The heating wire is energized, and the viscosity of the viscous liquid or semi-solid grease attached to the electric field 40 decreases, making it easier to flow. Under the action of gravity, this part of the grease that was originally stuck on the electric field 40 separates from the electric field 40 and enters the oil channel, and flows into the oil collection tank 1023 along the oil channel, realizing the self-cleaning of the electric field 40. It is obvious that compared with the prior art, this application has the advantage of being able to clean the oil stains in the electric field 40.

[0043] Furthermore, such as Figures 6 to 8 As shown, the oil-separating and air-dispersing mesh 30 includes a mesh frame and a plurality of stacked aluminum foils 301. The aluminum foils 301 have a plurality of holes 3011, and the mesh frame wraps around the aluminum foils 301.

[0044] It should be noted that the mesh frame is a flat cuboid shape, and the aluminum foil 301 is stacked inside it. It should also be noted that the aluminum foil 301 is first... Figure 7 As shown, the aluminum foil 301 has multiple cutting strips 3012 arranged in an array. After the four sides of the aluminum foil 301 are fixedly connected to the mesh frame, the aluminum foil 301 is in a stretched state, and each cutting strip 3012, after being stretched, forms as shown in the image. Figure 8The diamond-shaped holes 3011 shown are, in this application, 12 aluminum foils 301, and the holes 3011 on the 12 layers of aluminum foils 301 are staggered. When the hot oily fumes pass through the oil-separating and air-distributing mesh 30, the fumes first hit the surface of the outermost aluminum foil 301, and some oil droplets are captured, converting kinetic energy into heat energy. The heat is quickly conducted through the aluminum foil 301 to the entire metal structure. The aluminum foil 301 absorbs some heat through its own heat capacity. At the same time, the airflow is divided into multiple thin streams, which repeatedly contact the cold aluminum foil 301 in the tortuous channel to achieve continuous heat dissipation. After being cooled step by step by multiple layers of staggered aluminum foils 301, the final output oily fume temperature is significantly reduced, and the oily fumes sent to the electric field 40 are more uniform.

[0045] Furthermore, such as Figure 3 and Figure 9 As shown, the intelligent and energy-saving oil fume purification system also includes a flow interception module 60. The flow interception module 60 includes an outer cylinder 601 and an inner cylinder 602. The outer cylinder 601 is rotatably fitted onto the inner cylinder 602. The outer cylinder 601 has a plurality of first vent holes 6011, and the inner cylinder 602 has a plurality of second vent holes 6021. When the outer cylinder 601 and the inner cylinder 602 rotate relative to each other by a predetermined angle, the first vent holes 6011 are directly opposite the second vent holes 6021, or the first vent holes 6011 and the second vent holes 6021 are misaligned.

[0046] It should be noted that when the purification capacity of the electric field 40 is not diminished by oil stains, the fan 50 operates at full power, and the first vent 6011 is directly opposite the second vent 6021. At this time, the flow cross-sectional area of ​​the intercepting module 60 is at its maximum per unit time, and the oil fumes filtered by the oil filter plate 20 pass through the intercepting module 60 with the largest flow area. As the purification capacity of the electric field 40 gradually decreases, since the amount of oil fumes that the electric field 40 can purify per unit time is constant, in order to avoid excessive oil fumes being ineffectively sent into the electric field 40 and eventually discharged, the outer cylinder 601 and the inner cylinder 602 rotate relative to each other, and the first vent 6011 and the second vent 6021 are aligned. With the partial misalignment, the flow cross-sectional area of ​​the intercepting module 60 per unit time decreases, so that less flue gas can pass through the intercepting module 60 per unit time, matching the purification capacity of the electric field 40 at this time. At the same time, the power of the fan 50 also decreases adaptively to avoid unnecessary losses and achieve the purpose of intelligent energy saving. It should also be noted that at this time, the user's intuitive feeling is that the fume extraction function of the oil fume purification system is not as good as before, thus giving the user an intuitive feeling to remind them that the electric field 40 can be cleaned, that is, by pressing the cleaning button to energize and heat the heating wire on the electric field 40, so as to reduce the grease remaining on the electric field 40 and improve the purification capacity of the electric field 40.

[0047] Furthermore, such as Figure 9 As shown, the inner cylinder 602 has a cooling assembly 70 at its top, a cavity 6022, second vent holes 6021 spaced apart on the sidewall of the cavity 6022, and an opening at the bottom of the cavity 6022. Figure 11 As shown, the top wall side of the cylindrical cavity 6022 has an annular cavity 6023, and the top of the inner cylinder 602 also has several placement slots 6024 arranged in an annular array. Each placement slot 6024 is connected to the annular cavity 6023, and each placement slot 6024 is provided with oil-absorbing cotton 6025. The inner cylinder 602 is rotatably mounted on the housing 10, and there is a delay structure 80 between the inner cylinder 602 and the outer cylinder 601.

[0048] It should be noted that when the purification capacity of the electric field 40 is not diminished by oil stains, the inner cylinder 602 does not rotate circumferentially. It should also be pointed out that at this time, the outer cylinder 601 does not rotate circumferentially relative to the inner cylinder 602. Under the action of the fan 50, the oil fumes pass through the first vent 6011 and the second vent 6021, and after passing through the oil-separating and air-distributing mesh 30 and the electric field 40 in sequence, are discharged to the outside from the outlet of the fan 50. This process... The flue gas is unlikely to enter the annular cavity 6023 located at the top of the cylindrical cavity 6022 and be absorbed by the oil-absorbing cotton 6025; when the purification capacity of the electric field 40 is lost due to oil stains, by rotating the inner cylinder 602 circumferentially, the outer cylinder 601 sleeved on the outside of the inner cylinder 602 also rotates circumferentially. Moreover, by setting the delay structure 80, the inner cylinder 602 first rotates independently by a predetermined angle, and then drives the outer cylinder 601 to rotate accordingly. This allows for the staggered arrangement of the first vent 6011 and the second vent 6021, reducing the flow rate of oil fumes passing through the intercepting module 60 per unit time to accommodate the purification capacity of the electric field 40. It should also be noted that because the amount of oil fumes passing through the intercepting module 60 per unit time is reduced, the oil fumes have a longer residence time after entering the cylindrical cavity 6022. Simultaneously, by activating the cooling component 70, the temperature of the top wall of the cylindrical cavity 6022 decreases. The higher-temperature oil fumes condense upon contact with the top wall of the cylindrical cavity 6022, forming oil droplets. As the inner cylinder 602 rotates circumferentially, the oil droplets on the top wall of the cylindrical cavity 6022 enter the annular cavity 6023 under centrifugal force and are absorbed by the oil-absorbing cotton 6025. This compensates for the reduced purification capacity of the intelligent energy-saving oil fume purification system when the electric field 40's purification capacity decreases.

[0049] Furthermore, to specifically implement the delay structure 80, such as... Figure 13 As shown, the outer sidewall of the top of the inner cylinder 602 has several protrusions 801, and the inner sidewall of the top of the outer cylinder 601 has several arc-shaped grooves 802. The protrusions 801 extend into the arc-shaped grooves 802. The protrusions 801 and the arc-shaped grooves 802 together form the delay structure 80. The delay structure 80 also includes a spring piece 803. The spring piece 803 is disposed at the end of the arc-shaped groove 802 opposite to the protrusions 801. The spring piece 803 is fixedly connected to the outer cylinder 601. Figure 11 As shown, the inner cylinder 602 and the outer cylinder 601 are connected by a torsion spring 603.

[0050] It should be noted that, under normal conditions, when the inner cylinder 602 is not rotating circumferentially, under the torsion of the torsion spring 603, the second vent 6021 on the inner cylinder 602 is directly opposite the first vent 6011 on the outer cylinder 601; when the inner cylinder 602 rotates circumferentially, the inner cylinder 602 overcomes the torsion of the torsion spring 603, and the protrusion 801 slides a predetermined distance in the arc groove 802 and then contacts the spring 803, further driving the outer cylinder 601 to rotate circumferentially. At this time, the second vent 6021 and the first vent 6011 are misaligned and partially overlap. By adjusting the rotation speed of the inner cylinder 602, the force exerted by the protrusion 801 on the spring 803 changes, thereby realizing the change of the overall flow cross-sectional area of ​​the intercepting module 60 per unit time.

[0051] Furthermore, to specifically implement the cooling component 70, such as... Figure 9 As shown, the cooling assembly 70 includes a cooling tank 701, two connecting pipes 702, a pump body 703, and a return pipe 704. The top of the inner cylinder 602 has a cooling channel 705, as shown. Figure 10 As shown, the cooling channel 705 consists of two interconnected spiral channels, and the two spiral channels are respectively connected to the connecting pipe 702. One of the connecting pipes 702 is connected to the cooling box 701, and the other connecting pipe 702 is connected to the inlet of the pump body 703. The two ends of the return pipe 704 are connected to the outlet of the pump body 703 and the cooling box 701. The cooling box 701 is filled with coolant.

[0052] It should be noted that when the pump body 703 is working, the coolant circulates into and out of the cooling channel 705, and reduces the temperature of the top wall of the cylinder cavity 6022.

[0053] Furthermore, to achieve the rotation of the inner cylinder 602 without affecting the arrangement of the cooling channel 705, such as... Figure 9 As shown, the flow interception module 60 also includes a rotary motor 604. The rotating shaft of the rotary motor 604 has a through hole 6041. The connecting pipe 702 passes through the through hole 6041. The rotating shaft of the rotary motor 604 is fixedly connected to the inner cylinder 602. The rest of the structure of the rotary motor 604 is the same as that of the existing motor, including a rotor core fixedly connected to the rotating shaft, a stator core sleeved on the outside of the rotor core, and front and rear end covers connected to the stator core. These will not be described in detail here.

[0054] In addition, a first wind speed sensor is provided in the fan cavity 1013, and a second wind speed sensor is provided in the purification cavity 1012. The drive motor of the fan 50 is preferably a variable frequency motor. The intelligent energy-saving oil fume purification system also includes a controller. The first wind speed sensor, the second wind speed sensor, the variable frequency motor, the heating wire, the pump body 703, and the rotary motor 604 are all connected to the controller circuit. When the intelligent energy-saving oil fume purification system is operating normally, if the difference between the flue gas flow rate detected by the first wind speed sensor and the flue gas flow rate detected by the second wind speed sensor in the purification cavity 1012 reaches a predetermined value, the system will automatically activate the fan 50. When the value is set, it is considered that the electric field 40 is blocked by grease. The controller then reduces the speed of the variable frequency motor and energizes and rotates the rotary motor 604, reducing the flow rate of flue gas passing through the intercepting module 60 per unit time. The pump body 703 is also activated, allowing the coolant to continuously flow to the top wall of the cylinder 6022 until the heating wire has been heated for a predetermined time and the purification capacity of the electric field 40 has been restored to a good state. At this time, the difference between the data measured by the first wind speed sensor and the second wind speed sensor will be lower than the predetermined value. The controller then increases the rotation of the variable frequency motor again and stops the pump body 703, the heating wire, and the rotary motor 604.

[0055] In summary, the intelligent and energy-saving fume purification system based on the embodiments of this application is explained, which provides advantages such as the ability to clean oil stains in the electric field and the ability to adjust energy consumption when the purification capacity of the electric field decreases.
