Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to an electric purification dust collecting device. Background Art

[0002] As the market demand for air purifiers increases, the use scenarios of air purifiers are becoming more and more extensive, and users' performance requirements for air purifiers are becoming more and more stringent. For air purifiers that use physical interception and filtration purification technology, there are problems such as high resistance, need for replacement, and risk of secondary pollution; for air purifiers that use electrical purification technology, although the circulation resistance is reduced to a certain extent, there are also disadvantages such as low processing efficiency and large size.

[0003] In view of some problems existing in the existing air purifiers, there are not only some technical defects, but also the scope of application of the air purifiers is limited in some occasions. For example, the resistance of the air purifier used in conjunction with the air conditioner cannot be too high, and the efficiency cannot be too low; for example, in some cases where the installation space is limited, an air purifier that is too thick cannot be used. Utility Model Content

[0004] In view of this, the utility model provides an electric purification dust collecting device to solve the technical problems of the air purifier in the prior art that the structure is bulky and the efficiency is low.

[0005] In the first aspect, the utility model provides an electric purification dust collecting device, which is arranged as a window frame structure, and the electric purification dust collecting device includes: a frame, which is arranged as a hollow structure surrounded by peripheral frame plates; a discharge electrode, which is arranged on a first side of the peripheral frame plate; a grounding electrode, which is arranged on a second side of the peripheral frame plate opposite to the first side, and an ionization zone is formed between the discharge electrode and the grounding electrode at the hollow structure; a dust collecting layer, which is arranged on the peripheral frame plate and is located in the ionization zone, and the dust collecting layer is arranged to collect dust in the ionization zone.

[0006] Beneficial effect: The electric purification dust collecting device proposed in this embodiment integrates the discharge electrode and the grounding electrode on the frame of the electric purification dust collecting device, so that an ionization zone can be formed inside the frame, so that the dust in the frame can be absorbed by the dust collecting layer when it is fully ionized, thereby achieving the technical effect of lightweight and high efficiency of the electric purification dust collecting device.

[0007] Specifically, the electric purification dust collecting device proposed in this embodiment combines the flat, light and compact properties of the window frame structure with the efficient dust collecting performance of the discharge electrode, grounding electrode and dust collecting layer of the electric purification technology, so that the electric purification dust collecting device can take into account the advantages of lightness and high efficiency. On the basis of not affecting the dust collecting performance of the electric purification dust collecting device, the spatial applicability of the electric purification dust collecting device is improved.

[0008] One side of the window frame structure is set as the air inlet side, and the opposite side of the window frame structure is set as the air outlet side. Dust and air enter the interior of the window frame structure from the air inlet side of the window frame structure. The dust is ionized by the discharge electrode and the grounding electrode inside the window frame structure and then absorbed by the dust collecting layer. The air is discharged through the air outlet side of the window frame structure, thereby achieving the purpose of filtering dust in the air. In addition, since the window frame structure has a larger side surface, the filtering area and filtering amount of the electric purification dust collector can be increased, thereby improving the filtering effect of the high electric purification dust collector.

[0009] In an optional embodiment, the discharge electrode includes a plurality of discharge elements, which are spaced apart and distributed on the first side of the peripheral frame plate and cover the hollow structure.

[0010] Beneficial effect: By covering the hollow structure with multiple discharge elements, the area of ​​the ionization zone formed by the multiple discharge elements can be increased, thereby improving the filtration area and filtration efficiency of the electric purification dust collector. Furthermore, the multiple discharge elements are spaced apart so that the gap between two adjacent discharge elements can form an airflow channel, thereby improving the flow efficiency of the airflow and reducing the flow resistance of the airflow.

[0011] In an optional embodiment, the discharge element includes at least one of a metal wire, a barb, a sawtooth, a star shape, and a metal mesh.

[0012] Beneficial effects: Metal wires, barbs, saw teeth, stars, and metal meshes can all achieve the technical effect of increasing the filtration area and filtration efficiency of the electric purification dust collection device, as well as increasing the circulation efficiency of the airflow and reducing the circulation resistance of the airflow. Specifically, taking the discharge element as a barb or saw tooth as an example, two adjacent barbs or saw teeth are staggered, which can not only reduce the phenomenon of overlapping waste between two adjacent barbs or saw teeth, but also increase the coverage area of ​​two adjacent barbs or saw teeth on one side of the frame, thereby increasing the ionization area of ​​the discharge element. Taking the discharge element as a metal wire or metal mesh as an example, this method can increase the coverage area of ​​the plasma in the ionization zone, so as to cover the entire dust collection area on the side of the frame. At the same time, the discharge will be more uniform and the ionization degree will be more complete, achieving the effect of high-efficiency dust removal.

[0013] In an optional embodiment, the grounding electrode includes a plurality of grounding elements, which are spaced apart and distributed on the second side of the peripheral frame plate and cover the hollow structure.

[0014] Beneficial effect: By covering the hollow structure with multiple grounding elements, the area of ​​the ionization zone formed by the multiple grounding elements can be increased, thereby improving the filtration area and filtration efficiency of the electric purification dust collector. Furthermore, the multiple grounding elements are spaced apart so that the gap between two adjacent grounding elements can form an airflow channel, thereby improving the circulation efficiency of the airflow and reducing the circulation resistance of the airflow.

[0015] In an optional embodiment, the grounding element includes at least one of a metal wire, a barb, a sawtooth, a star, and a metal mesh.

[0016] Beneficial effects: Metal wires, thorns, sawteeth, stars, and metal meshes can all achieve the technical effect of increasing the filtration area and filtration efficiency of the electric purification dust collection device, as well as increasing the flow efficiency of the airflow and reducing the flow resistance of the airflow.

[0017] In an optional implementation, when the discharge electrode and the grounding electrode are both configured as metal wires, a projection of each discharge electrode to the second side is located at a gap between two adjacent grounding electrodes.

[0018] Beneficial effect: Each discharge electrode is arranged at equal intervals to the gap between two adjacent grounding electrodes, such as the central axis. Each discharge electrode and the corresponding two grounding electrodes form a triangular discharge area, thereby ensuring that the interior of the entire frame is placed in the ionization zone, and the charging and dust collection functions can be simultaneously realized in the ionization zone. Compared with the traditional method of generating plasma on one side and then blowing it into the dust collection area, the electric purification dust collecting device of the present application greatly improves the charging efficiency of particulate matter. At the same time, the layout integrates the discharge electrode and the grounding electrode into an integrated design, which reduces the occupied space of the electric purification dust collecting device, solves the technical problems of the heavy weight and low efficiency of the electric purification dust collecting device, and also increases the scope of application of the electric purification dust collecting device.

[0019] In an optional embodiment, the dust collecting layer includes dust collecting high voltage electrodes and dust collecting grounding electrodes alternately distributed along the length direction of the frame, and the dust collecting high voltage electrodes and dust collecting grounding electrodes are respectively connected to the power supply and grounding terminals of the electric purification dust collecting device.

[0020] Beneficial effect: The dust collecting layer is arranged in a circular pattern in which the dust collecting high voltage electrode and the dust collecting grounding electrode are arranged in parallel, so that a higher electric field can be provided between the two repelling electrodes, and a higher dust collecting area can be achieved under the same area. Therefore, even if the thickness of the dust collecting layer is reduced, the filtration efficiency of the dust collecting layer can be guaranteed, thereby achieving the lightweight effect of the dust collecting layer and the electric purification dust collecting device.

[0021] In an optional embodiment, the dust collecting layer includes a sandwich structure in which a PET layer, an ink layer, and a PET layer are stacked in sequence, and the PET layer, the ink layer, and the PET layer are stacked in sequence along the length direction of the frame.

[0022] Beneficial effects: The embodiment of the present application has made improvements in the structure of the dust collecting layer, retaining the low resistance advantage of the traditional plate-type dust collecting layer, and then selected a sandwich structure in which PET, ink, and PET are stacked in sequence, thereby reducing the dust collecting distance inside the dust collecting layer. The polymer insulating material constituting the PET layer can withstand a higher discharge voltage due to its high surface resistance and low surface roughness. At the same time, the smooth and uniform surface morphology can reduce the phenomenon of edge sparking in the dust collecting layer.

[0023] In an optional embodiment, the dust collecting layer includes a plurality of sandwich structures spaced apart along the length direction of the frame, and the gap between two adjacent sandwich structures is set to range from 1 mm to 2.5 mm.

[0024] Beneficial effect: The dust collecting layer is arranged in a circular pattern in the order of parallel arrangement of the dust collecting high-voltage electrode and the dust collecting grounding electrode. The gap range between two adjacent sandwich structures is set to 1mm~2.5mm through the formula, so that a higher electric field can be provided between the two repelling electrodes, and a higher dust collecting area can be achieved under the same area. Therefore, even if the thickness of the dust collecting layer is reduced, the filtration efficiency of the dust collecting layer can be guaranteed, thereby achieving the lightweight effect of the dust collecting layer and the electric purification dust collecting device.

[0025] In an optional embodiment, a first insulating spacer is provided between the periphery of the discharge electrode and the periphery of the dust collecting layer, and / or a second insulating spacer is provided between the periphery of the grounding electrode and the periphery of the dust collecting layer, and the thickness range of the insulating spacer is set to 3 mm to 5 mm.
