Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and more specifically, to an indoor air conditioner unit and an air conditioner. Background Technology

[0002] Existing air conditioning indoor units typically disperse air through diffuser panels. Specifically, these panels have perforations running along their thickness. However, these perforations are both aesthetically unappealing and inefficient in terms of airflow. Furthermore, the limited area occupied by these perforations, coupled with the small size of each perforation and low airflow velocity, results in overall limited airflow. Utility Model Content

[0003] The first objective of this utility model is to provide an air conditioner indoor unit to solve the technical problem of low air volume in existing air conditioner indoor units in zero-wind mode.

[0004] The first aspect of this utility model provides an indoor air conditioning unit, which includes a housing. The front surface of the housing is provided with a front panel air outlet and / or the lower surface of the housing is provided with a lower air outlet. The front panel air outlet and / or the lower air outlet are provided with a grille-faced diffuser.

[0005] The beneficial effects of this air conditioner indoor unit are:

[0006] By setting up a grille-mounted air diffuser plate, and using the air diffuser grille rod in the grille-mounted plate as a component to space the air diffuser holes, the proportion of the area occupied by the air diffuser holes in the grille-mounted air diffuser plate can be significantly increased, thereby increasing the overall air outlet area in the air diffuser mode and improving the air volume in the air diffuser mode.

[0007] In an optional technical solution, the grille surface diffuser includes multiple grille layers, each grille layer including multiple grille grids. The grille grids of the grille layer located downstream of the air outlet direction have planar rods, and planar diffuser holes are formed between the planar rods of each grille grid. The edges of the grille grids are provided with three-dimensional diagonal rods. Multiple three-dimensional diagonal rods extending from the edge of the same grille grid intersect, and three-dimensional diffuser holes are formed between the intersecting three-dimensional diagonal rods that form a closed shape and the planar diagonal rods, and / or three-dimensional diffuser holes are formed between the intersecting three-dimensional diagonal rods that form a closed shape.

[0008] By combining a grid mesh section and a three-dimensional diagonal bar section into a grille-faced air diffuser, the airflow can be diffused once using the grid mesh section and again using the three-dimensional air diffuser holes formed by the three-dimensional diagonal bar sections extending from the edges of the same grid mesh. This allows the airflow to be dispersed twice as it passes through the same grille-faced air diffuser, by both the planar and three-dimensional air diffuser holes, thus improving the airflow dispersion effect. Furthermore, because the three-dimensional air diffuser holes are inclined relative to the grid mesh section, although the three-dimensional diagonal bar section occupies part of the projected area of ​​the planar air diffuser holes, the total area of ​​multiple three-dimensional air diffuser holes may still be larger than the area of ​​the planar air diffuser holes, without reducing the ventilation area, ensuring a large airflow rate through the grille-faced air diffuser.

[0009] In an optional technical solution, multiple three-dimensional diagonal bars extending from the edge of the same grid mesh intersect at the same vertex.

[0010] This configuration allows for mutual support among the various three-dimensional diagonal braces, thereby increasing their rigidity. Furthermore, it eliminates the possibility of small cross-section holes that might occur when multiple three-dimensional diagonal braces are used compared to multiple points. These small cross-section holes, although through holes, are essentially unable to provide ventilation. As a result, the cross-sectional area of ​​the various three-dimensional ventilation holes formed by the three-dimensional diagonal braces and the planar braces can be increased.

[0011] In an optional technical solution, multiple three-dimensional diagonal bars extending from the edge of the same grid mesh are located on the edge of a regular polygonal pyramid.

[0012] This design maximizes and maintains the consistent area of ​​each three-dimensional air diffuser hole, resulting in a more uniform airflow distribution effect. Furthermore, because the three-dimensional inclined rods are the edges of a regular polygonal pyramid, the stress on each rod is consistent, preventing uneven stress on some parts and avoiding inconsistent deformation or premature damage to others due to uneven load distribution.

[0013] In an optional technical solution, the outer shell is provided with a first magnetic attraction part, and the grille surface attached to the air diffuser is provided with a second magnetic attraction part. The first magnetic attraction part and the second magnetic attraction part are correspondingly arranged and attracted together.

[0014] By setting the first magnetic suction part and the second magnetic suction part to be set and attracted together, the installation is simple. After the indoor unit of the air conditioner is installed, since there is no significant vibration or impact, the magnetism of the first magnetic suction part and / or the second magnetic suction part is not easy to disappear. Therefore, the grille surface attached to the air diffuser can be fixed for a long time.

[0015] In an optional technical solution, the edge of the air diffuser plate on the grille surface is provided with a second magnetic attraction part, and the edge of the front surface or the edge of the lower surface of the housing is provided with a first magnetic attraction part.

[0016] For indoor air conditioning units, the various positions of the grille-faced air diffuser are not too far from the edge of the grille-faced air diffuser. Fixing the grille-faced air diffuser to the outer casing at the edge position can basically fix the grille-faced air diffuser relative to the outer casing. Even in areas of the grille-faced air diffuser that are far from the fixed position, there will be no obvious deformation.

[0017] In an optional technical solution, the front surface of the housing is provided with a mounting grille, the mounting grille is located inside the air outlet of the front panel, the middle part of the mounting grille is provided with a first magnetic attraction part, and the middle part of the grille surface attached to the air diffuser is correspondingly provided with a second magnetic attraction part.

[0018] By installing a grille, not only can a first magnetic part be installed on it to attract a second magnetic part in the middle of the grille surface attached to the air diffuser, so that the middle area of ​​the grille surface attached to the air diffuser is also fixed by the attraction of the first and second magnetic parts, but the installation grille is set at the large opening of the front panel air outlet, which can also improve the rigidity of the front of the air conditioner indoor unit and avoid the serious reduction of the rigidity of the front of the air conditioner indoor unit casing due to the large opening.

[0019] In an optional technical solution, the mounting grille includes intersecting grille bars, and the intersection of the grille bars is provided with the first magnetic attraction part.

[0020] The grid strips are arranged in a cross pattern, and a first magnetic attraction part is set at the intersection. For these first magnetic attraction parts, two grid strips can be used to bear the force of the first magnetic attraction part, thereby effectively improving the positional stability of the first magnetic attraction part and thus improving the rigidity of the middle area of ​​the grid surface attached to the air diffuser.

[0021] In an optional technical solution, the indoor unit of the air conditioner is a wall-mounted indoor unit. The wall-mounted indoor unit includes a main unit module and a lower frame. The lower frame includes a base plate, the base plate has a lower air outlet, and the base plate has a first magnetic suction part around the lower air outlet.

[0022] Since the area of ​​the lower air outlet on the bottom plate of the grille-faced air diffuser is the main area affected by the airflow, a first magnetic part is set in the area surrounding the lower air outlet on the bottom plate, and a corresponding second magnetic part is set on the grille-faced air diffuser. This allows the fixed position to be closer to the area affected by the wind, thereby reducing the deformation of the grille-faced air diffuser caused by the airflow and improving the reliability of the fixation.

[0023] The second objective of this utility model is to provide an air conditioner that solves the technical problem of low air volume output of the indoor unit in zero-wind mode.

[0024] The air conditioner provided in the second aspect of this utility model includes an indoor unit and an outdoor unit of the air conditioner as described above, wherein the outdoor unit is connected to the indoor unit of the air conditioner via a refrigerant connection pipe.

[0025] By installing the aforementioned indoor unit in the air conditioner, the air conditioner will have all the advantages of the aforementioned indoor unit, which will not be elaborated here. Attached Figure Description

[0037] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

Furthermore, "inner" and "outer" are defined based on the shape of a cavity, box, or cylinder; the side of the cavity, box, or cylinder facing its internal space is the inner side, and the outer side is the side of the cavity or box facing its external space.

[0039] Example 1:

[0040] Figure 1 This is a structural schematic diagram of the indoor unit of the air conditioner provided in Embodiment 1 of this utility model. Figure 2 This is a schematic diagram of the structure of the indoor unit of the air conditioner after omitting the grille and attaching the air diffuser plate, as provided in Embodiment 1 of this utility model. Figures 1-3 As shown, the air conditioner indoor unit provided in Embodiment 1 of this utility model includes a housing 100. The front surface of the housing 100 is provided with a front panel air outlet 110 and the lower surface of the housing 100 is provided with a lower air outlet 120. The front panel air outlet 110 and the lower air outlet 120 are provided with a grille surface attached air diffuser 200.

[0041] By setting up a grille-mounted air diffuser plate 200, and using the air diffuser grille rod in the grille as a component to space the air diffuser holes, the proportion of the area occupied by the air diffuser holes in the grille-mounted air diffuser plate 200 can be significantly increased, thereby increasing the overall air outlet area in the air diffuser mode and improving the air volume in the air diffuser mode.

[0042] This embodiment takes a wall-mounted air conditioner indoor unit as an example. The wall-mounted air conditioner indoor unit includes a main unit module 130 and a lower frame 140. The lower frame 140 is connected to the bottom of the main unit module 130 and is located below the main unit module 130. The left and right side walls of the main unit module 130 extend downward naturally and are fixedly connected to the base plate 141. The side walls extending downward from the bottom of the main unit module 130 and the base plate 141 together constitute the lower frame 140. A lower air outlet 120 can be provided on the base plate 141.

[0043] Specifically, in this embodiment, grille-faced air diffusers 200 are respectively provided on the front side of the front surface of the outer casing 100 and on the lower side of the bottom plate portion 141. The outer casing 100 of the air conditioner indoor unit is not necessarily limited to a casing located on the outside of the middle frame; part of the casing may be omitted, and the middle frame may be used directly as the outer casing 100 to install the grille 160 surfaced air diffusers.

[0044] Figure 3 This is a schematic diagram of the structure of the air diffuser plate attached to the grille surface in the indoor unit of the air conditioner provided in Embodiment 1 of this utility model. Figure 4 This is a schematic diagram of the structure of the air conditioning indoor unit provided in Embodiment 1 of this utility model, viewed from another direction, showing the grille-faced air diffuser. Figure 5 This is a side view of the air diffuser plate attached to the grille surface of the indoor unit of an air conditioner according to Embodiment 1 of this utility model. Figures 3 to 5 As shown, optionally, the grille surface diffuser 200 includes multiple grille mesh layers, each including multiple grille grids. The grille grids of the grille mesh layer located downstream of the air outlet direction have planar rod portions 210, and planar diffuser holes are formed between the planar rod portions 210 of each grille grid. The edges of the grille grids are provided with three-dimensional inclined rod portions 220. Multiple three-dimensional inclined rod portions 220 extending from the edges of the same grille grid intersect, and three-dimensional diffuser holes are formed between the three-dimensional inclined rod portions 220 that intersect and form a closed shape and the planar inclined rod portions.

[0045] By configuring the grille-faced diffuser 200 as a combination of a grille mesh portion and a three-dimensional diagonal bar portion 220, the airflow can be diffused once using the grille mesh portion, and also once using the three-dimensional diffuser holes formed by the three-dimensional diagonal bar portions 220 extending from the edge of the same grille mesh. This allows the airflow to be dispersed twice as it passes through the grille-faced diffuser 200, by both the planar and three-dimensional diffuser holes, thus improving the diffusion effect. Furthermore, since the three-dimensional diffuser holes are inclined relative to the grille mesh portion, although the three-dimensional diagonal bar portion 220 occupies part of the projected area of ​​the planar diffuser holes, the total area of ​​the multiple three-dimensional diffuser holes may still be larger than the area of ​​the planar diffuser holes, without reducing the ventilation area. This ensures a larger airflow rate through the grille-faced diffuser 200.

[0046] In this embodiment, each grille layer distributed perpendicular to the thickness direction of the grille surface diffuser 200 has planar air diffusers formed by planar rods 210. Alternatively, in another implementation, only the grille layer located at the downstream end of the air outlet direction may have planar rods 210, while the remaining grille layers may not have planar rods 210. By having planar rods 210 on the downstream grille layer, a unified plane can be formed on the front and / or bottom surface of the indoor unit—the surface directly observable by the user during normal use. Compared to the outermost surface, which is a three-dimensional angled rod 220, this improves the user's perception and reduces dust adhesion caused by uneven airflow surfaces, thus extending the normal service life of the grille surface diffuser 200. If the grid layer other than the outermost grid layer that is directly observed by the user does not include the planar bar portion 210, then the three-dimensional air diffuser can also be formed between the three-dimensional oblique bar portions 220 that intersect and form a closed shape.

[0047] Taking a square grid as an example in this embodiment, three-dimensional diagonal rods 220 extend from each of the four corners of the square. Triangles can be formed between the three-dimensional diagonal rods 220 and the planar rods 210. Since the plane containing these triangles is not the plane containing the planar air diffuser, the total area of ​​the multiple triangles can be greater than the area of ​​the planar air diffuser without reducing the ventilation area. Alternatively, in another implementation, a three-dimensional diagonal rod 220 can extend from each of the two opposite corners of the square. Or, the three-dimensional diagonal rods 220 can extend from three corners of the square or two adjacent corners, which can also disperse the airflow from the planar air diffuser.

[0048] Furthermore, the three-dimensional inclined rod portion 220 in this embodiment can be a straight rod. Of course, in other implementations, the three-dimensional inclined rod portion 220 can be an arc-shaped rod. For example, multiple three-dimensional inclined rod portions 220 can be located on the same ellipsoid or sphere, and the radial symmetry plane of the ellipsoid or sphere is located on the plane where the planar air diffuser is located.

[0049] like Figures 3 to 5 As shown, optionally, multiple three-dimensional diagonal bars 220 extending from the edge of the same grid intersect at the same vertex.

[0050] This configuration allows the various three-dimensional diagonal braces 220 to support each other, thereby increasing the rigidity of each individual three-dimensional diagonal brace 220. Furthermore, it eliminates the possibility of very small cross-sectional holes that might result from multiple three-dimensional diagonal braces 220 compared to multiple points. These small cross-sectional holes, although through holes, are essentially unable to provide ventilation. Therefore, this solution can increase the cross-sectional area of ​​the various three-dimensional air diffusers formed by the three-dimensional diagonal braces 220 and the planar braces 210.

[0051] It should be noted that the projection of the same vertex of the multiple intersecting three-dimensional inclined rods 220 along the direction perpendicular to the planar air diffuser should be located inside the planar air diffuser. Therefore, the multiple three-dimensional inclined rods 220 intersecting at the same vertex can disperse the airflow passing through the planar air diffuser.

[0052] like Figures 3 to 5 As shown, optionally, multiple three-dimensional diagonal bars 220 extending from the edge of the same grid are located on the edge of a regular polygonal pyramid.

[0053] This design maximizes and maintains the consistent area of ​​each three-dimensional air diffuser hole, resulting in a more uniform air distribution effect from the diffuser plate. Furthermore, because the three-dimensional inclined rod 220 is an edge of a regular polyhedron, the stress on each of the three-dimensional inclined rods 220 is consistent. This prevents some three-dimensional inclined rods 220 from experiencing uneven stress, which could lead to inconsistent deformation or premature damage due to uneven load distribution.

[0054] In this embodiment, the same vertex of the intersection of multiple three-dimensional diagonal rods 220 is projected along a direction perpendicular to the planar air diffuser hole and located at the geometric center of the planar air diffuser hole. In other words, the three-dimensional diagonal rods 220 extending from the corner of the same grid mesh and the planar rods 210 of the grid mesh together form a regular polygonal pyramid.

[0055] Specifically, in this embodiment, if the grid mesh is square, then the multiple three-dimensional oblique rods 220 are located at the edges of a regular square pyramid, and the multiple three-dimensional oblique rods 220 and the planar rods 210 form a regular square pyramid. If the grid mesh is equilateral triangular, then the multiple three-dimensional oblique rods 220 are located at the edges of a regular triangular pyramid, and the multiple three-dimensional oblique rods 220 and the planar rods 210 form a regular triangular pyramid. If the grid mesh is regular hexagonal, that is, the grid mesh is honeycomb-shaped, then the multiple three-dimensional oblique rods 220 are located at the edges of a regular hexagonal pyramid, and the multiple three-dimensional oblique rods 220 and the planar rods 210 form a regular hexagonal pyramid.

[0056] like Figures 2 to 5 As shown, optionally, the outer casing 100 is provided with a first magnetic attraction part 150, and the grille surface air diffuser 200 is provided with a second magnetic attraction part 230. The first magnetic attraction part 150 and the second magnetic attraction part 230 are correspondingly arranged and attracted together.

[0057] By setting the first magnetic suction part 150 and the second magnetic suction part 230 to be correspondingly set and attracted together, the installation is simple. After the indoor unit of the air conditioner is installed, since there is no significant vibration or impact, the magnetism of the first magnetic suction part 150 and / or the second magnetic suction part 230 is not easy to disappear. Therefore, the grille surface attached to the air diffuser plate 200 can be fixed for a long time.

[0058] In this embodiment, the first magnetic attraction part 150 and the second magnetic attraction part 230 can be magnets or a combination of magnets and ferromagnetic materials, respectively. For example, the magnetic poles of the first magnetic attraction part 150 and the second magnetic attraction part 230 have the same direction of arrangement. Specifically, taking the example of the air diffuser plate 200 attached to the grille surface and set at the lower air outlet 120, the lower end of the first magnetic attraction part 150 is the S pole and the upper end is the N pole, while the upper end of the second magnetic attraction part 230 is the N pole and the lower end is the S pole. When the air diffuser plate 200 is installed on the base plate 141, the N pole at the upper end of the first magnetic attraction part 150 and the S pole at the lower end of the second magnetic attraction part 230 attract each other to fix the first magnetic attraction part 150 and the second magnetic attraction part 230. Of course, one of the first magnetic attraction part 150 and the second magnetic attraction part 230 can be a magnet, while the other is an iron sheet or iron column. The first magnetic part 150 is fixed to the outer shell 100, while the second magnetic part 230 is fixed to the grille surface diffuser 200. Specifically, the first magnetic part 150 is fixed to the outer shell 100 and the second magnetic part 230 is fixed to the grille surface, which can be done by snap-fit ​​or adhesive.

[0059] like Figures 2 to 5 As shown, optionally, the edge of the grille surface attached to the air diffuser plate 200 is provided with a second magnetic part 230, and the edge of the front surface or the edge of the lower surface of the housing 100 is provided with a first magnetic part 150.

[0060] For the indoor unit of the air conditioner, the various positions of the grille surface diffuser 200 are not too far from the edge of the grille surface diffuser 200. By fixing the grille surface diffuser 200 to the outer casing 100 at the edge, the grille surface diffuser 200 can be basically fixed relative to the outer casing 100. Even in areas of the grille surface diffuser 200 that are far from the fixed position, there will be no obvious deformation.

[0061] Specifically, taking a wall-mounted air conditioner indoor unit as an example, generally speaking, the length of a typical wall-mounted air conditioner indoor unit is less than one meter or about one meter, while its height is usually less than half a meter. The length and width of the grille surface diffuser 200 are correspondingly smaller than the length of the wall-mounted air conditioner indoor unit. Therefore, the furthest distance between the grille surface diffuser 200 and the fixed edge is no more than 300mm. After the edge is fixed by magnetic attraction, it can also effectively affect these areas that are far from the fixed position.

[0062] Specifically, in this embodiment, taking a wall-mounted air conditioner indoor unit as an example, ten second magnetic attachment parts 230 can be provided along the longitudinal edge of the grille surface diffuser plate 200, and five second magnetic attachment parts 230 can be provided along the width edge of the grille surface diffuser plate 200. Specifically, if the grille surface diffuser plate 200 is rectangular, the second magnetic attachment parts 230 can be provided at the four corners of the rectangle. The position of the first magnetic attachment part 150 on the surface of the outer casing 100 corresponds to the second magnetic attachment parts 230.

[0063] like Figures 2 to 5 As shown, optionally, the front surface of the housing 100 is provided with a mounting grille 160, which is located inside the air outlet 110 of the front panel. The middle part of the mounting grille 160 is provided with a first magnetic attraction part 150, and the middle part of the grille surface attached to the air diffuser 200 is correspondingly provided with a second magnetic attraction part 230.

[0064] By setting the mounting grille 160, not only can the first magnetic part 150 be set on it to attract the second magnetic part 230 in the middle of the grille surface attached to the air diffuser 200, so that the middle area of ​​the grille surface attached to the air diffuser 200 is also fixed by the attraction of the first magnetic part 150 and the second magnetic part 230, but the mounting grille 160 is set in the large opening of the front panel air outlet 110, which can also improve the rigidity of the front part of the air conditioner indoor unit and avoid the serious reduction of the rigidity of the front part of the air conditioner indoor unit casing 100 due to the large opening.

[0065] It should be noted that the middle part of the grille surface diffuser 200 is not limited to the area of ​​the grille surface that is closest to the center in the length and width directions. In fact, in this application, the middle part of the grille surface diffuser 200 refers to the area of ​​the grille surface diffuser 200 excluding the edge area.

[0066] like Figures 2 to 5 As shown, optionally, the mounting grille 160 includes intersecting grille bars, and the intersection of the grille bars is provided with a first magnetic attraction part 150.

[0067] The grid strips are arranged in a cross pattern, and a first magnetic attraction part 150 is set at the intersection. For these first magnetic attraction parts 150, the two grid strips can be used to bear the force of the first magnetic attraction part 150, thereby effectively improving the positional stability of the first magnetic attraction part 150 and thus improving the rigidity of the middle area of ​​the grid surface attached to the air diffuser plate 200.

[0068] Specifically, in this embodiment, a mounting grille 160 is provided at the front panel outlet of the wall-mounted air conditioner indoor unit. The mounting grille 160 is formed by perpendicularly intersecting grille bars, and the grille bars form a 45° angle with both the length and height directions of the front panel outlet. Of course, in another implementation, the grille bars can be aligned with the length direction of the front panel air outlet 110.

[0069] like Figures 1 to 2 As shown, optionally, the indoor unit of the air conditioner is a wall-mounted air conditioner indoor unit. The wall-mounted air conditioner indoor unit includes a main unit module 130 and a lower frame 140. The lower frame 140 includes a base plate 141, the base plate 141 is provided with a lower air outlet 120, and a first magnetic suction part 150 is provided around the lower air outlet 120 on the base plate 141.

[0070] Since the area of ​​the lower air outlet 120 of the grille-mounted air diffuser 200 facing the bottom plate 141 is the main area affected by the airflow, a first magnetic part 150 is provided in the area surrounding the lower air outlet 120 of the bottom plate 141, and a corresponding second magnetic part 230 is provided on the grille-mounted air diffuser 200. This allows the fixed position to be closer to the area affected by the wind, thereby reducing the deformation of the grille-mounted air diffuser 200 caused by the airflow and improving the reliability of the fixation.

[0071] Specifically, in this embodiment, a first magnetic attraction part 150 is also provided on the edge area of ​​the lower surface of the base plate 141 of the wall-mounted air conditioner indoor unit to fix the edge portion of the grille surface attached to the air diffuser plate 200. Furthermore, first magnetic attraction parts 150 are provided around the lower air outlet 120 of the base plate 141. Specifically, three first magnetic attraction parts 150 are provided on the left and right sides of each lower air outlet 120, and the three first magnetic attraction parts 150 are arranged in a generally front-to-back direction.

[0072] Example 2:

[0073] Figure 6 This is a three-dimensional disassembled view of the indoor unit of the air conditioner provided in Embodiment 2 of this utility model. Figure 7 This is a three-dimensional disassembled view of the air diffuser plate and the mounting grille in the indoor unit of the air conditioner provided in Embodiment 2 of this utility model. Figure 7 For clarity, the planar rods, three-dimensional diagonal rods, and air diffusers on the grille surface are not shown. Figure 6 and Figure 7 As shown, this embodiment provides an air conditioner indoor unit. The difference between this embodiment and Embodiment 1 is that the air conditioner indoor unit is a cabinet-type air conditioner indoor unit. The cabinet-type air conditioner indoor unit has two front panel air outlets 110, and each front panel air outlet 110 is provided with a grille sticker. Correspondingly, in this embodiment, each front panel air outlet 110 can also be provided with a mounting grille 160 to provide a first magnetic suction part 150.

[0074] Example 3:

[0075] Embodiment 3 also provides an air conditioner, including the above-mentioned indoor air conditioner unit.

[0076] By installing the aforementioned indoor unit in the air conditioner, the air conditioner will have all the advantages of the aforementioned indoor unit, which will not be elaborated here.

[0077] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.

[0078] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the term "comprising" or any other variations thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
