Description

Technical Field

[0001] The invention relates to the technical field of kitchen air conditioners, and in particular to an oil fume filtering component and a kitchen air conditioner. Background Art

[0002] The kitchen air conditioner has an integrated oil fume filter device, which achieves the integration of the kitchen air conditioner and the range hood system. The use of traditional air conditioners in the kitchen will cause the evaporator of the internal unit to become dirty and blocked, and the oil accumulation will block the entire machine, resulting in poor heat exchange. The oil will deteriorate, causing the internal unit to emit odor, causing health hazards and other adverse consequences.

[0003] Kitchen air conditioners need to have built-in filters to filter out the fumes. Traditional filters need to be relatively fine to filter out the fumes, and the fumes accumulate and are difficult to clean. The filtering effect gradually deteriorates over time and can only be replaced. Finer filters will produce a lot of wind resistance, making it difficult to ensure air volume.

[0004] In summary, the kitchen air conditioner in the prior art uses a relatively fine filter, which makes it difficult to ensure the air volume. Summary of the invention

[0005] An oil fume filter assembly and a kitchen air conditioner are provided in the embodiments of the present invention to solve the problem in the prior art that the kitchen air conditioner is difficult to ensure the air volume due to the use of a relatively fine filter mesh.

[0006] To achieve the above-mentioned purpose, the present invention provides an oil fume filter component, comprising: an air duct structure, the first end of which takes in air and the second end of which discharges air; a sound wave generating component, which is arranged in the air duct structure, and the sound wave generating component is used to stimulate the fusion of oil fume particles; and a filter net, which is arranged downstream of the sound wave generating component along the airflow direction.

[0007] Furthermore, the oil fume filtering assembly also includes: a fan assembly, the fan assembly is arranged corresponding to the air duct structure, and the fan assembly is used to drive the airflow.

[0008] Further, the filter is connected to the second end of the air duct structure, and the fan assembly is arranged in the air duct structure;

[0009] The fan assembly is arranged upstream of the sound wave generating assembly along the air flow direction, and the fan assembly is located between the first end of the air duct structure and the sound wave generating assembly.

[0010] Furthermore, the filter screen is arranged in the air duct structure, and the fan assembly is arranged downstream of the filter screen.

[0011] Furthermore, it also includes: a coarse filter screen, and the coarse filter screen is arranged at the first end position of the air duct structure.

[0012] Furthermore, it also includes: an oil collection mechanism, which is arranged in the air duct structure and is located at the bottom of the sound wave generating component.

[0013] Furthermore, the oil collection mechanism includes an oil storage groove, and the oil storage groove is connected to an external oil discharge pipeline.

[0014] Furthermore, the oil collection mechanism comprises an oil collecting structure, and the oil collecting structure is arranged at an upstream position of the oil storage groove along the air flow direction;

[0015] The oil-collecting structure has a plurality of sawtooth structures arranged in sequence along the airflow direction, the windward surface of the sawtooth structure is an inclined surface, the leeward surface of the sawtooth structure is a vertical surface, the first end of the windward surface of the sawtooth structure is the lowest position of the sawtooth structure, the second end of the windward surface of the sawtooth structure is the highest position of the sawtooth structure, and the second end of the windward surface of the sawtooth structure is connected to the leeward surface of the sawtooth structure.

[0016] Furthermore, it also includes: an auxiliary sound wave generator, which is arranged in the air duct structure, the auxiliary sound wave generator is located at an upstream position of the oil-collecting structure along the air flow direction, and the auxiliary sound wave generator sends sound waves toward the oil-collecting structure.

[0017] According to another aspect of the present invention, a kitchen air conditioner is provided, comprising the above-mentioned oil fume filter assembly.

[0018] Furthermore, the air inlet of the kitchen air conditioner is connected to the first end of the air duct structure, and the second end of the air duct structure is connected to the heat exchange air duct of the kitchen air conditioner; the evaporator of the kitchen air conditioner is arranged in the heat exchange air duct.

[0019] Furthermore, the kitchen air conditioner comprises an air conditioning panel, on which an air inlet and an air outlet of the kitchen air conditioner are arranged, wherein the air inlet is provided with a grille, and the air outlet is provided with a filtering structure.

[0020] Furthermore, the filtering structure is detachably connected to the air conditioning panel via a positioning structure.

[0021] The oil fume filter assembly of the present invention is installed at the air inlet of the kitchen air conditioner to filter the oil fume of the air entering the kitchen air conditioner. The air with oil fume particles enters the air duct structure from the first end of the air duct structure. Since the sound wave generating assembly is added to the air duct structure, the tiny oil fume particles are excited by the sound wave generating assembly, and the sound pressure is inconsistent at different positions, which prompts the oil fume particles to move to the low pressure position. Since the sound wave excitation is directional, the movement of the particles is also directional. When a large number of particles move towards each other and collide, the probability of the tiny oil fume particles combining is greatly increased, so that the extremely tiny oil fume particles merge into larger oil fume particles. The larger oil fume particles form small droplets and enter the filter screen for filtration. Finally, the clean air flows into the evaporator after passing through the filter screen to perform heat exchange. By setting the sound wave generating assembly, the filter screen can fully filter the oil fume particles. Therefore, a standard filter screen can be used instead of a finer filter screen, which will not generate a large wind resistance, ensure the air intake of the kitchen air conditioner, and improve the cooling effect of the kitchen air conditioner.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0029] Embodiment 1

[0030] See also Figure 1As shown, according to the first embodiment of the present invention, there is provided an oil fume filter assembly, which includes an air duct structure 10, an acoustic wave generating assembly 20 and a filter 30, wherein the air is taken in at the first end of the air duct structure 10 and the air is discharged at the second end of the air duct structure 10; the acoustic wave generating assembly 20 is arranged in the air duct structure 10, and the acoustic wave generating assembly 20 is used to stimulate the fusion of oil fume particles; the filter 30 is arranged downstream of the acoustic wave generating assembly 20 along the airflow direction.

[0031] The oil fume filter assembly of the present invention is installed at the air inlet of the kitchen air conditioner to filter the oil fume of the air entering the kitchen air conditioner. The air with oil fume particles enters the air duct structure from the first end of the air duct structure. Since the sound wave generating assembly is added to the air duct structure, the tiny oil fume particles are excited by the sound wave generating assembly, and the sound pressure is inconsistent at different positions, which prompts the oil fume particles to move to the low pressure position. Since the sound wave excitation is directional, the movement of the particles is also directional. When a large number of particles move towards each other and collide, the probability of the tiny oil fume particles combining is greatly increased, so that the extremely tiny oil fume particles merge into larger oil fume particles. The larger oil fume particles form small droplets and enter the filter screen for filtration. Finally, the clean air flows into the evaporator after passing through the filter screen to perform heat exchange. By setting the sound wave generating assembly, the filter screen can fully filter the oil fume particles. Therefore, a standard filter screen can be used instead of a finer filter screen, which will not generate a large wind resistance, ensure the air intake of the kitchen air conditioner, and improve the cooling effect of the kitchen air conditioner.

[0032] Preferably, the oil fume filtering assembly further includes a fan assembly 40, and the fan assembly 40 is arranged corresponding to the air duct structure 10, and the fan assembly 40 is used to drive the airflow.

[0033] The function of the fan assembly 40 is to increase the air intake again to ensure the air intake of the kitchen air conditioner.

[0034] In this embodiment, the filter 30 is connected to the second end of the air duct structure 10, and the fan assembly 40 is disposed in the air duct structure 10;

[0035] The fan assembly 40 is disposed upstream of the sound wave generating assembly 20 along the air flow direction, and the fan assembly 40 is located between the first end of the air duct structure 10 and the sound wave generating assembly 20 .

[0036] After the air is blown in, it passes through the fan assembly and then into the air duct structure, and reaches the sound wave generating assembly. Under the action of the sound wave generating assembly, tiny oil smoke particles gather and are filtered through the filter. The clean airflow enters the air inlet of the kitchen air conditioner and is then sent to different rooms in the room (such as the kitchen) through multiple air vents.

[0037] The sound wave generating assembly can be composed of two symmetrically placed sound wave generators, the two sound wave generators output in phase, and the sound wave stagnation point is located in the middle of the cavity of the air duct structure. The sound wave generating assembly can also be composed of a sound wave generator and a strong reflective surface. The sound wave generating assembly can be composed of a single microphone or a series of sound wave generator arrays arranged in a straight line.

[0038] The cavity size of the air duct structure should be designed in detail so that the sound waves emitted by the sound wave generator and the reflected sound waves converge in the middle of the cavity to achieve the best effect.

[0039] There can be multiple filters arranged in series to further improve the filtration rate of oil fume particles in the air. The air passes through the filter repeatedly to improve the filtration efficiency of oil fume.

[0040] Embodiment 2

[0041] See also Figure 2 As shown, according to the second embodiment of the present invention, there is provided an oil fume filter assembly, which includes an air duct structure 10, an acoustic wave generating assembly 20 and a filter 30, wherein the first end of the air duct structure 10 takes in air, and the second end of the air duct structure 10 discharges air; the acoustic wave generating assembly 20 is arranged in the air duct structure 10, and the acoustic wave generating assembly 20 is used to stimulate the fusion of oil fume particles; the filter 30 is arranged downstream of the acoustic wave generating assembly 20 along the airflow direction.

[0042] Preferably, the filter screen 30 is disposed in the air duct structure 10 , and the fan assembly 40 is disposed downstream of the filter screen 30 .

[0043] The biggest advantage of setting the fan assembly 40 downstream of the filter 30 is that it can prevent oil smoke particles from adhering to the fan assembly, which is beneficial to the life of the motor. The fan assembly is also not easily contaminated by oil smoke, and is convenient for cleaning and maintenance.

[0044] Combination Figure 2 As shown, the oil fume filter assembly further includes a coarse filter 50 , and the coarse filter 50 is disposed at the first end of the air duct structure 10 .

[0045] After the air is blown in, it first passes through a group of coarse filters to filter out large particles of pollutants in the air. The air then directly enters the location of the sound wave generating component. The fan component is installed after the filter. The air passes through the fan component after being purified. This layout allows most of the components to be located on the clean side, which is not easily contaminated, is conducive to cleaning and maintenance, and the motor is not exposed to oil smoke, which is beneficial to the life of the motor.

[0046] The oil fume filtering assembly further includes an oil collection mechanism, which is disposed in the air duct structure 10 and is located at the bottom of the sound wave generating assembly 20 .

[0047] The oil collection mechanism collects the accumulated oil at the bottom of the air duct structure, which is convenient for cleaning after the collection is completed.

[0048] Some oil may gather at the bottom of the air duct structure and need to be cleaned regularly. How to efficiently gather these oils together is a key technical point. To address the above problem, the oil collection mechanism of this embodiment includes an oil storage groove 61, and the oil storage groove 61 is connected to an external oil drain pipeline.

[0049] The oil storage groove 61 can collect the oil in the air duct structure and then discharge it from the external oil drain pipe, thereby increasing the collection efficiency and the convenience of cleaning.

[0050] The oil storage groove 61 can also be cleaned regularly by means of high-pressure water flow, automatic spraying of detergent, etc., so that the kitchen air conditioner can achieve the function of self-cleaning, which greatly reduces the time and energy spent by users on cleaning, and achieves the effect of filtering oil smoke and self-cleaning of the kitchen air conditioner.

[0051] Furthermore, the oil collection mechanism includes an oil collecting structure 62, and the oil collecting structure 62 is arranged at an upstream position of the oil storage groove 61 along the air flow direction;

[0052] See also Figure 3 The oil-collecting structure 62 has a plurality of sawtooth structures 63 arranged in sequence along the airflow direction, the windward surface 63a of the sawtooth structure 63 is an inclined surface, the leeward surface 63b of the sawtooth structure 63 is a vertical surface, the first end of the windward surface 63a of the sawtooth structure 63 is the lowest position of the sawtooth structure 63, the second end of the windward surface 63a of the sawtooth structure 63 is the highest position of the sawtooth structure 63, and the second end of the windward surface 63a of the sawtooth structure 63 is connected to the leeward surface 63b of the sawtooth structure 63.

[0053] Rows of sawtooth structures are designed to collect oil. During the flow of air, some oil droplets will move on the sawtooth structure toward the oil storage groove. The leeward side 63b of the sawtooth structure 63 is a vertical surface, which prevents the oil from flowing in the opposite direction and increases the efficiency of oil collection.

[0054] The oil fume filtering assembly also includes an auxiliary sound wave generator 70, which is arranged in the air duct structure 10. The auxiliary sound wave generator 70 is located at an upstream position of the oil collecting structure 62 along the air flow direction, and the auxiliary sound wave generator 70 sends sound waves toward the oil collecting structure 62.

[0055] The surface of the sawtooth structure will collect large oil droplets generated by the stimulation of the sound wave generating component. An auxiliary sound wave generator 70 is placed on one side. The pressure difference of the sound wave causes the oil droplets to cross the sawtooth structure and reach the position of the next tooth. The leeward side 63b of the sawtooth structure 63 is a vertical surface to prevent the reverse flow of oil. The sound wave pressure difference and the special structure of the sawtooth structure can achieve the effect of driving the oil to migrate autonomously without any moving parts, thereby reducing the need for maintenance.

[0056] The filtering effect of a traditional filter is related to the total area of ​​the filter. The larger the area of ​​the filter, the better the filtering effect. However, the area of ​​the filter cannot be increased indefinitely. The structural design of the present invention gathers tiny oil droplets in the air through the principle of acoustic resonance, achieving the effect of gathering sand into a tower, making the oil droplets passing through the filter larger and easier to filter out, so that the size of the filter can be smaller. Because the principle of acoustic resonance is adopted, the resonance cavity is a larger cavity. Compared with traditional filters, the resistance is very small, the demand for fan power is much smaller, and energy consumption is saved.

[0057] The oil fume filter assembly of the present invention can be integrated into the interior of a kitchen air conditioner, or can be used as a separate integrated air outlet component to become an optional accessory of the whole machine. It can be seen that the oil fume filter assembly has higher versatility and can be flexibly configured.

[0058] Embodiment 3

[0059] See also Figures 4 to 6 As shown, according to the third embodiment of the present invention, a kitchen air conditioner is provided, and the kitchen air conditioner includes the above-mentioned oil fume filter assembly.

[0060] Wind with tiny oil fume particles enters the oil fume filter assembly from the air inlet of the kitchen air conditioner, becomes clean air after passing through the sound wave generating assembly and the filter, and enters the evaporator of the kitchen air conditioner for heat exchange. The kitchen air conditioner of the present invention improves the filtering efficiency of small-diameter oil fume particles, and when used with the filter, greatly expands the range of droplet diameters that can be filtered. At the same time, the system wind resistance is not increased, and the air intake loss is reduced while ensuring the same air intake volume.

[0061] Preferably, the air inlet 81 of the kitchen air conditioner is connected to the first end of the air duct structure 10, and the second end of the air duct structure 10 is connected to the heat exchange air duct of the kitchen air conditioner; the evaporator of the kitchen air conditioner is arranged in the heat exchange air duct.

[0062] The air duct structure of the oil fume filtering component can be integrated into the kitchen air conditioner, which greatly reduces the volume of the kitchen air conditioner and facilitates installation and decoration layout.

[0063] In this embodiment, the kitchen air conditioner includes an air conditioning panel 83 , on which an air inlet 81 and an air outlet 82 of the kitchen air conditioner are provided. The air inlet 81 is provided with a grille 91 , and the air outlet 82 is provided with a filtering structure 92 .

[0064] The grille 91 plays a preliminary filtering role and can also close the air inlet when the kitchen air conditioner is not in use to prevent oil smoke and dust from entering, thereby increasing the service life of the kitchen air conditioner. The function of the filter structure 92 provided on the air outlet is to prevent oil smoke from entering the heat exchange air duct from the air outlet 82, comprehensively protect the evaporator in the heat exchange air duct, and reduce the impact of oil smoke on the kitchen air conditioner.

[0065] See also Figure 6 The filter structure 92 is detachably connected to the air conditioning panel 83 through the positioning structure 93. The filter structure 92 can be disassembled and cleaned regularly, and the positioning structure 93 can select a variety of structural forms, such as the cooperation of the limit buckle and the slot, or the combination of the hook and other structures. The positioning structure 93 can improve the assembly efficiency and facilitate the inspection and disassembly.
