detailed description

Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

In the present invention, unless stated to the contrary, the used orientation words such as "up, down, top, bottom" generally refer to the directions shown in the drawings or refer to the vertical, perpendicular or gravitational directions The terms used to describe the mutual positional relationship of the various components mentioned above.

Aiming at the common electrostatic devices in the prior art, due to the complex structure of needle poles or electrode plates, etc., there are problems such as bulky overall device structure, many parts, time-consuming installation, low space utilization, etc., the present invention provides an electrostatic device. The electrostatic device includes one or a plurality of stacked electrostatic units, and the electrostatic unit includes at least one discharge module 1 and at least one collection module 2 stacked. Wherein, in order to make the device have a good oil fume adsorption and condensation effect, the height of the collection module 2 should be increased as much as possible. Therefore, in the electrostatic device of the present invention, the total stacking height of the discharge modules 1 is smaller than the total stacking height of the collection modules 2 .

The electrostatic device shown in FIG. 1 includes two electrostatic units, the two electrostatic units have the same structure, and both include a discharge module 1 and a collection module 2 stacked together. Refer to FIGS. 2 and 3 for details. It should be noted that the above FIG. 1 is only a preferred form of the electrostatic device of the present invention, and is not limited thereto. For example, the number of collecting modules 2 may be more than that of the discharging module 1, therefore, the electrostatic device may also be a structure in which one discharging module 1 and two collecting modules 2 are stacked.

Specifically, the discharge module 1 includes a paired discharge cell electrode frame 11 and a discharge needle module 12, and the collection module 2 includes a paired collection cell electrode frame 21 and a collection needle module 22, a discharge cell electrode frame and a collection cell electrode frame. All comprise a plurality of honeycomb units adjacent to each other, the honeycomb unit includes a honeycomb column hole and an electrode enclosure around the honeycomb column hole, the collecting needle module 22 is provided with a plurality of collecting needles 221, and the collecting needles 221 are collected from the honeycomb One side of the electrode frame 21 is inserted into the honeycomb column holes of a plurality of collecting honeycomb electrode frames 21 in one-to-one correspondence. The discharge needle module 12 is provided with a plurality of discharge needles 121, and the plurality of discharge needles 121 are connected from the discharge honeycomb electrode frame. One side of 11 is inserted into the honeycomb post holes of a plurality of discharge honeycomb electrode frames 11 in one-to-one correspondence. Since the electrostatic device of the present invention is a honeycomb electrostatic device, compared with the structure of electrode plate to electrode plate or needle plate to electrode plate, its electrostatic field is more uniform, and its effect on oil fume adsorption is better.

Since the electrostatic device of the present invention is mainly used for range hoods in domestic kitchens, etc., considering that each module of the electrostatic device should not only achieve its own installation performance, but also save the internal space of the structure, as shown in Figures 5 and 6, Wherein, the total height h1 of the discharge module 1 (there may be multiple discharge modules 1) is preferably 20mm˜50mm. At the same time, the collection module 2 can also be a stack of a plurality of collection modules 2, and the total height h2 of the collection module 2 is preferably 40mm˜100mm.

Compared with the electrostatic device in the prior art where the total height h2 of the collection module 2 and the total height h1 of the discharge module 1 are the same or similar, the total height h2 of the above collection module 2 is set higher than the total height h1 of the discharge module 1, Therefore, the electrostatic device of the present invention has a stronger adsorption and condensation effect on oil smoke.

Compared with the prior art, the electrode plate requires a single, multiple times of cumbersome operations of disassembling and fixing. In the electrostatic device of the present invention, the collecting needle module 22 and the discharging needle module 12 are respectively integrated in the form of components. a module. Specifically, as shown in FIG. 3 , the collection needle module 22 and the discharge needle module 12 all include conductive honeycomb panels, and a plurality of honeycomb holes are formed in the honeycomb panels, and the collection needles 221 and the discharge needles 121 are connected from the corresponding honeycomb. The plates extend vertically outward. The collecting needles 221 and the discharging needles 121 are installed on the honeycomb board, and there are many ways of fixing them, such as welding. The honeycomb board is the installation frame of the collection needle 221 and the discharge needle 121, which not only enables the collection needle 221 and the discharge needle 121 to be installed in one structure, the collection needle module 22 and the discharge needle module 12, but also allows the smoke Air passes through the electrostatic device smoothly along each honeycomb hole to reduce flow resistance.

Wherein, the cross-sections of the discharge needle 121 and the collection needle 221 are preferably circular. Specifically, circular needles are easier to process, less likely to accumulate grease, and combined with the interspersed structure of the porous plate with the above-mentioned honeycomb holes, the advantages are more prominent, because when the airflow such as oil fume passes through the electrostatic device, the needles with a circular structure The pole also rectifies the flue gas flow to a certain extent, so it has a certain effect on reducing the noise of the whole machine.

In order to make the flue gas flow more smoothly, so as to reduce wind resistance, the honeycomb column holes and the honeycomb holes are all set as polygonal holes of the same size, as shown in Figures 1 to 6, the polygonal holes are preferably regular hexagons, and the collecting needle module 22 and the honeycomb holes in the discharge needle module 12 are aligned one by one, and the honeycomb holes and the honeycomb column holes are misaligned so that the collecting needles 221 and the discharge needles 121 are located at the axis of the honeycomb column holes. Therefore, the multi-module structure of the electrostatic device forms a uniform porous honeycomb structure with a certain depth, which has a rectifying effect on the flue gas fluid, and can also effectively optimize the noise of the whole machine and achieve the effect of noise reduction. Moreover, the collection needle module 22 and the discharge needle module 12 are arranged at the axis of the honeycomb column hole of the electrode shroud, which can ensure that the electric field in the electrostatic device is more uniform, and the discharge needle 121 can discharge evenly.

Because all can form high-voltage electrostatic field when electrostatic device electrification, so collecting needle pole module 22, collecting honeycomb electrode frame 21, discharging needle pole module 12 and discharging honeycomb electrode frame 11 all comprise insulating outer frame, collecting needle pole module 22, collecting honeycomb electrode frame The electrode frame 21, the discharge needle module 12 and the discharge honeycomb electrode frame 11 are respectively installed in the corresponding insulating outer frame. The insulating outer frame can play the role of high-voltage electrostatic isolation and protection, and at the same time avoid creepage and electrostatic device leakage between the electrode plate and the range hood shell.

The insulating outer frames of the collecting needle module 22 , the collecting honeycomb electrode frame 21 , the discharging needle module 12 and the discharging honeycomb electrode frame 11 are all rectangular. Wherein, the four corners of the insulating outer frames of the collecting needle module 22 and the discharging needle module 12 are all provided with insulating support columns 23, and the insulating supporting columns 23 of the collecting needle module 22 and the discharging needle module 12 respectively resist the collecting The upper and lower ends of the insulating outer frame of the honeycomb electrode frame 21 and the discharge honeycomb electrode frame 11. The insulating supporting columns 14 are respectively fixedly connected to the discharge module 1 and the collection module 2 of the electrostatic device. The fixed connection method is a preferred method, but obviously the connection method of the electrostatic device of the present invention is not limited thereto.

In addition, the present invention also provides a range hood, as shown in FIG. 7 , the range hood includes the above-mentioned electrostatic device, and its collection module 2 is located downstream of the discharge module 1 in the direction of the oil fume passing. Specifically, particles such as oily fume pass through the discharge modules 1 of the multiple electrostatic units of the electrostatic device (to be ionized) and then pass through the collection module 2 (to be adsorbed), so as to purify the oily fume. Since the electrostatic device of the present invention is a superposition of multiple electrostatic units, and the electrostatic device is a honeycomb electrostatic device, its electric field is more stable, so that the ionization amount and adsorption amount of the oil fume have a superimposed effect, thus enhancing the range hood. Oil fume adsorption effect, and the electrostatic device increases the height of the collection module 2, strengthens the oil fume adsorption and condensation effect, and further enhances the oil fume purification effect of the range hood of the present invention.

The electrostatic device of the range hood of the present invention is also convenient for cleaning and replacement. The electrostatic device shown in Figure 1 includes two stacked electrostatic units. When the oil fume enters from the lower end of the electrostatic device, it first passes through the first electrostatic unit, and most of the grease is adsorbed on the first layer of collecting module 2; when the oil fume enters the second layer of electrostatic unit, the oil fume particles continue to charge Electricity, when passing through the second layer of collection module 2, the grease is adsorbed to the polar plate of the collection module 2 again under the action of the electrostatic field. In addition, since the electrostatic units on the second layer are polluted for a longer period than the electrostatic units on the first layer, when the first layer of modules is polluted, they need to be cleaned or replaced in time, while the second layer of electrostatic units can still play a role in removing oil fume The role of the range hood will not cause other parts of the range hood to be polluted.

Preferably, the end of the discharge needle 121 is formed as a vertical upward discharge tip. The discharge tip of the discharge needle 121 in the range hood of the present invention is installed towards the air outlet, which can make the grease not easy to gather on the surface of the discharge tip under the action of gravity, so the discharge tip can maintain stable and long-lasting discharge, thereby improving the single discharge module 1 The ionization effect finally improves the fume purification efficiency of the range hood.

The preferred embodiment of the present invention has been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the specific details of the above embodiment, within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, These simple modifications all belong to the protection scope of the present invention. , For example, the collection needle and the discharge needle are detachably installed in the honeycomb panel (its corresponding needle installation hole).

In addition, it should be noted that the various specific technical features described in the above specific implementation manners may be combined in any suitable manner if there is no contradiction. In order to avoid unnecessary repetition, various possible combinations are not further described in the present invention.

In addition, various combinations of different embodiments of the present invention can also be combined arbitrarily, as long as they do not violate the idea of the present invention, they should also be regarded as the disclosed content of the present invention.
