Description

Technical Field

[0001] This invention relates to a component for a filter unit, a filter unit, and an air purification system. Background Technology

[0002] Currently, there are various solutions available for designing air-guiding components on filter assemblies. With the increasing number of air filters in the air purification system field and the growing demands for higher quality and performance, the need for innovative and robust solutions for addressing air guidance is constantly increasing. Summary of the Invention

[0003] Through embodiments of the present invention, improved components for a filtering unit can be advantageously provided. The invention is defined in the independent claims. Advantageous further developments of the invention are derived from the dependent claims and the following description.

[0004] The advantage of a component having the features of claim 1 is that the differential pressure between the air inlet and air outlet sides of the component can be optimized. Therefore, in particular, the multiple profiles can prevent premature separation of the airflow from the surface of the component. More preferably, the component can reduce energy losses, which are primarily generated by the formation of vortices as the airflow exits the component.

[0005] This is achieved according to the invention by means of a component for a filter unit arranged in an airflow that at least partially passes through the filter unit, wherein the component has a plurality of contours at least in a predetermined region, the plurality of contours being arranged relative to each other according to a predetermined pattern, wherein the plurality of contours are configured to at least partially form a turbulent boundary layer to reduce the flow resistance of the airflow on the component.

[0006] In other words, a turbulent boundary layer can be formed using multiple contours, which can improve the flow characteristics of the airflow. For example, the multiple contours can be designed and positioned relative to each other in conjunction with a predetermined pattern, such that they can form a golf ball structure or sharkskin or the like. Preferably, the contours can be recesses, ridges, or the like. The predetermined pattern defines the position of the contours relative to each other. In the case where the contours are spherical recesses, the center point of each of these recesses can be used as a reference part of the pattern, so that multiple adjacent recesses can be created. For example, a turbulent boundary layer can be generated by means of a golf ball structure when the airflow flows through the multiple predetermined contours. Due to the turbulent boundary layer at the multiple contours, the airflow adheres for a longer time compared to previous solutions or smooth surfaces. For example, the multiple contours can be introduced by means of an injection molding tool when forming the component. More preferably, the component can be a housing element of a filter unit.

[0007] The dependent claims illustrate advantageous further developments of the invention.

[0008] More preferably, the plurality of contours each have a substantially spherical recess.

[0009] The advantage of this implementation is that the spherical recess can be relatively easily introduced into the component during the molding process using a suitable plastic injection molding tool, so that the manufacturing cost of the component remains low even when the functionality of the component is increased. More preferably, recesses or similar objects designed as spherical, partially spherical, crown-shaped, or similar shapes also fall under the term "substantially spherical recess".

[0010] More preferably, the plurality of substantially spherical recesses, in conjunction with a predetermined pattern, are configured to form a golf ball structure to create a turbulent boundary layer.

[0011] The advantage of this implementation is that the golf ball structure can be well adapted to the corresponding flow velocity through the component. Preferably, the recesses can be constructed as so-called pits, which form a structure that reduces surface friction. Small, regular turbulence is created by the recesses, which separates the fluid from the component and reduces overall drag. A turbulent boundary layer can be formed by the multiple regular turbulences. More preferably, the pressure difference at the component can be further reduced by the combined action of the guide ribs and the multiple recesses.

[0012] More preferably, the component has a first surface and a second surface, wherein the first surface and the second surface are arranged substantially orthogonally to each other, and wherein the predetermined region is a transition region between the first surface and the second surface.

[0013] The advantage of this implementation is that the cost of introducing contours can be kept small, as these contours should only be arranged in the transition region based on the finding that the contours are particularly efficient in that region. Preferably, the first surface can be arranged substantially orthogonally to the second surface.

[0014] More preferably, the turbulent boundary layer is configured to at least partially retain the airflow on the component in the predetermined region along the flow direction of the airflow, such that the airflow moves from the point of separation from the component along the flow direction and along the predetermined region.

[0015] The advantage of this implementation is that the airflow is maintained on the component for a longer period of time and distance, resulting in a further reduction in flow resistance. More preferably, the component may have at least partially a nozzle that expands along the airflow, so that the airflow is maintained at the increased diameter of the nozzle for a longer period of time by means of a turbulent boundary layer.

[0016] Preferably, the component has a first section and a second section, wherein the first section may be arranged within the filter unit, wherein the second section may be arranged outside the filter unit, wherein the second section has a predetermined region with the plurality of contours, and wherein the first section has a plurality of second contours configured to form a second turbulent boundary layer to reduce the flow resistance of the component in the first section.

[0017] The advantage of this implementation is that the number and design of the contours can be adapted to the corresponding segments based on their locations. Therefore, different flow conditions can be addressed in a targeted manner.

[0018] More preferably, the component has a narrow section between the first section and the second section, wherein the second turbulent boundary layer in the first section is configured to reduce the flow resistance of the airflow toward the narrow section, and wherein the turbulent boundary layer in the second section is configured to reduce the flow resistance of the airflow away from the narrow section.

[0019] The advantage of this implementation is that, based on the different cross-sections of the component in the first and second sections, the airflow velocity is different, which allows for the reduction of effectiveness or total pressure loss by individually adapting the corresponding turbulent boundary layers in the first and second sections.

[0020] More preferably, the turbulent boundary layer and the second turbulent boundary layer are different from each other. Preferably, the first section has a first function and the second section has a second function, wherein the function of the first section is configured to support the formation of the second turbulent boundary layer, and wherein the function of the second section is configured to support the formation of the turbulent boundary layer.

[0021] More preferably, the plurality of contours are designed in association with a predetermined pattern to form sharkskin.

[0022] The advantage of this implementation is that, with the help of shark skin, there is a biomimetic means to reduce flow resistance on the component.

[0023] Another aspect of the invention relates to a filter unit having filter elements and components as described above and below, wherein the filter unit is configured to filter out predetermined selected elements from an airflow by means of the filter elements, and wherein the filter unit is configured to guide the airflow through the filter elements and components.

[0024] For example, the filter element may be a cartridge filter, a box filter, or the like. Preferably, the component may be at least partially embedded in the filter element, such that airflow can be directed through the filter unit and discharged at least partially through the component.

[0025] Another aspect of the present invention relates to an air purification system having the components described above and below and / or the filter unit described above and below.

[0026] Furthermore, it should be noted that the term "unit" here should also be understood broadly, including both single-piece and multi-piece constructions of the corresponding unit, wherein the corresponding sub-unit does not necessarily have to be located at one position in the filter unit or air purification system, but can also be distributed on the filter unit or air purification system.

[0034] As in Figure 1 As can be seen, multiple contours 14 can be constructed as substantially spherical recesses 17. When the spherical recesses 17 are arranged according to a predetermined pattern 16, they can form a golf ball structure 18, as shown in [the image / description]. Figure 1 As shown. More preferably, component 10 is in Figure 1The device has a first surface 20 and a second surface 22, which are arranged substantially orthogonally to each other. A predetermined region 12, in which the plurality of contours may be arranged, may be located in a transition region 24, which lies between the first surface 20 and the second surface 22. Figure 1 As shown, the transition region 24 can be a rounded portion or the like between the first surface 20 and the second surface 22.

[0035] Figure 2 A filter unit 100 according to one embodiment is shown. The filter unit 100 preferably has a filter element 102 on which a member 10 is disposed. The member 10 preferably has a plurality of contours 14 in a predetermined region 12, which are arranged relative to each other according to a predetermined pattern 16, such that the plurality of contours 14 can form a turbulent boundary layer to reduce the flow resistance of airflow on the member. Here, the airflow can, for example, first flow through the filter element and then from the interior of the filter element 102 through the member 10 to reach the environment.

[0036] Figure 3 A component 10 according to one embodiment is shown. The component 10 has a first section 30 and a second section 32, wherein the first section 30 may be arranged within a filter unit 100, and the second section 32 may be arranged outside the filter unit 100.

Here, the second turbulent boundary layer can preferably be configured to reduce the flow resistance of airflow toward the narrow portion 36, wherein the turbulent boundary layer of the second section 32 reduces the flow resistance of airflow away from the narrow portion 36. The turbulent boundary layer can preferably be configured to hold the airflow within a predetermined region 12 along the flow direction 26 of the airflow on the member 10, such that the airflow moves from the point 28 where it separates from the member 10 along the flow direction 26 and along the predetermined region 12. Figure 3 Example point 29 is shown where the airflow might split if multiple contours 14 are not provided. By arranging multiple contours 14, the airflow can be kept on the surface of the component 10 for a longer period of time along the flow direction 26, thereby further reducing flow resistance.
