Description

Technical Field

[0001] This invention relates to the field of air conditioning compressor technology, and particularly to a cylinder, a rolling rotor compressor, and an air conditioner. Background Technology

[0002] The cylinder body of a conventional compressor is generally circular. To create high and low pressure chambers, radial vane grooves are cut into the cylinder to accommodate vanes and rollers, forming the high-pressure chamber. However, cutting these grooves disrupts the circular integrity of the cylinder body. Under internal stress, the vane grooves tend to shrink inwards, resulting in a narrower groove width and worsened dimensional tolerances. This can lead to uneven vane movement within the grooves, reducing compressor performance. In severe cases, the vanes may become stuck in the grooves.

[0003] In other words, existing technologies have the problem that the vanes of rolling rotor compressors do not slide smoothly or get stuck in the radial vane grooves. Summary of the Invention

[0004] This invention provides a cylinder, a rolling rotor compressor, and an air conditioner to solve the problem of the sliding vanes of a rolling rotor compressor not sliding smoothly or getting stuck in the radial vane groove.

[0005] This invention provides a cylinder for a rolling rotor compressor, comprising:

[0006] The cylinder body has a rolling chamber inside, which is used to roll and cooperate with the rollers of the rolling rotor compressor.

[0007] The waist section, which is located on the outer peripheral wall of the cylinder body; and

[0008] The reinforcing part is provided on the outer peripheral wall of the cylinder body. One end of the reinforcing part is connected to the end of the waist part, and the other end of the reinforcing part extends along the circumference of the cylinder body.

[0009] The cylinder body and waist are provided with radial sliding grooves, which are connected to the rolling chamber. The reinforcement reduces the deformation of the radial sliding grooves by reducing the internal stress of cylinder contraction.

[0010] In one embodiment, the other end of the reinforcing part extends circumferentially along the cylinder body to the outer circular extension segment L of the cylinder body. The starting point of the outer circular extension segment L is on the outer circle of the cylinder body, and its ending point is on the outer circle of the waist. The line connecting the starting point of the outer circular extension segment L and the center of the outer circle of the cylinder body is a radius p. The radius p has an angle β with the first reference axis, wherein -15°≤β≤60°. The outer circular extension segment L has an angle α with the second reference axis, wherein -15°≤α≤60°. When the angle β is below the first reference axis, the angle β is positive; when it is above the first reference axis, the angle β is negative. When the angle α is outside the second reference axis, the angle α is positive; when it is inside the second reference axis, the angle α is negative.

[0011] In one embodiment, when both included angle α and included angle β are greater than 0°, the outer circle extension L is tangent to the outer circle of the cylinder body, and the outer circle extension L includes:

[0012] The first line segment L1 starts at the starting point of the extended outer circle segment L; and

[0013] The second line segment L2 starts at the end of the first line segment L1, and ends at the end of the outer circle extension segment L.

[0014] The second line segment L2 is parallel to the third reference axis, and the second line segment L2 and the third reference axis have a horizontal distance d. The range of the horizontal distance d is: r≤d≤R, where r is the outer diameter of the cylinder body and R is the outer diameter of the waist.

[0015] In one embodiment, when both included angle α and included angle β are greater than 0°, the outer circle extension L is tangent to the outer circle of the cylinder body, and a weight reduction hole is provided on the reinforcing part to reduce the weight of the cylinder.

[0016] In one implementation, the included angle α is equal to 20° and the included angle β is equal to 20°.

[0017] In one embodiment, the outer circular extension L includes:

[0018] The first line segment L1 starts at the starting point of the extended outer circle segment L; and

[0019] The second line segment L2, which comprises at least one line segment; and

[0020] The third line segment L3 ends at the end of the outer circle extension segment L;

[0021] When the second line segment L2 includes a single line segment, the starting point of the second line segment L2 is the ending point of the first line segment L1, and the ending point of the second line segment L2 is the starting point of the third line segment L3. When the second line segment L2 includes multiple line segments, the multiple line segments are connected in sequence, the starting point of the single line segment located at one end of the multiple line segments is the ending point of the first line segment L1, and the ending point of the single line segment located at the other end of the multiple line segments is the starting point of the third line segment L3.

[0022] In one embodiment, the other end of the reinforcing part extends circumferentially along the cylinder body to the outer circle extension segment L of the cylinder body. The starting point of the outer circle extension segment L is on the outer circle of the cylinder body, and its ending point is on the outer circle of the waist. The radius p between the starting point and the center of the outer circle of the cylinder body has an angle β with the first reference axis. The value range of the angle β is -15°≤β≤60°. The outer circle extension segment L is an arc segment. The starting point of the arc segment is on the outer circle of the cylinder body, and the ending point of the arc segment is on the outer circle of the waist.

[0023] In one embodiment, the thickness of the reinforcing part is h, and the thickness of the waist part is H, wherein the thickness h of the reinforcing part is less than or equal to the thickness H of the waist part.

[0024] In one embodiment, a positioning boss is also included, which is disposed on the outer peripheral wall of the cylinder body and is spaced apart from the reinforcing part along the outer periphery of the cylinder body.

[0025] This invention provides a rolling rotor compressor, comprising:

[0026] The aforementioned cylinder; and

[0027] Rollers, which are rolled within the rolling chamber of the cylinder; and

[0028] The sliding vane is slidably disposed within the radial sliding vane groove of the cylinder;

[0029] In this process, the rollers roll within the rolling chamber, and together with the sliding plate, the rolling chamber is divided into a low-pressure chamber and a high-pressure chamber.

[0030] The present invention provides an air conditioner comprising the above-described rolling rotor compressor.

[0031] Compared with existing technologies, the advantages of this invention lie in the addition of a reinforcing section to the existing cylinder structure. This reinforcing section strengthens the waist section and the connection between the waist section and the radial vane groove. This significantly reduces the internal stress of cylinder contraction, thereby reducing the deformation of the radial vane groove. This avoids problems such as uneven sliding of the vanes within the radial vane groove due to excessive deformation, and jamming of the vanes within the radial vane groove due to excessive deformation. Ultimately, this ensures smooth operation of the rolling rotor compressor. Attached Figure Description

[0054] The invention will now be further described with reference to the accompanying drawings.

[0055] It should be noted that the reference Figure 1 M1 is the horizontal axis passing through the center of the outer circle of the cylinder body, and M2 is the vertical axis passing through the center of the outer circle of the cylinder body. In this invention, the first reference axis is M1, the second reference axis is the axis passing through the starting point of the outer circle extension segment L and parallel to M2, and the third reference axis is M2, which is also the centerline in the radial sliding groove width direction.

[0056] It should be noted that in this invention, the included angle α being outside the second reference axis means that it is located on the side of the second reference axis away from M2, and the included angle α being inside the second reference axis means that it is located on the side of the second reference axis closer to M2.

[0057] Example 1

[0058] like Figure 1As shown, the present invention provides a cylinder for a rolling rotor compressor, comprising a cylinder body 10, a waist portion 20, and a reinforcing portion 30. The cylinder body 10 has a rolling chamber 11 for rolling engagement with the rollers 200 of the rolling rotor compressor. The waist portion 20 is disposed on the outer peripheral wall of the cylinder body 10; the reinforcing portion 30 is disposed on the outer peripheral wall of the cylinder body 10, one end of the reinforcing portion 30 is connected to one end of the waist portion 20, and the other end of the reinforcing portion 30 extends circumferentially along the cylinder body 10. Radial vane grooves 40 are formed on the cylinder body 10 and the waist portion 20, communicating with the rolling chamber 11. The reinforcing portion 30 reduces the deformation of the radial vane grooves 40 by reducing the internal stress of cylinder contraction.

[0059] In the above configuration, a reinforcing section 30 is added to the existing cylinder structure to strengthen the waist section 20 and the connection between the waist section 20 and the radial vane groove 40. This significantly reduces the internal stress of cylinder contraction, thereby reducing the deformation of the radial vane groove 40. This avoids problems such as uneven sliding of the vane 300 within the radial vane groove 40 due to excessive deformation, and jamming of the vane 300 within the radial vane groove 40 due to excessive deformation. Ultimately, this ensures the smooth operation of the rolling rotor compressor.

[0060] It should be noted that the deformation of the radial sliding groove 40 mentioned above mainly includes the deformation of the radial sliding groove 40 after the cylinder is cut online, during assembly and use.

[0061] Specifically, such as Figure 1 As shown, in one embodiment, the other end of the reinforcing portion 30 extends circumferentially along the cylinder body 10 to the outer circumferential extension segment L of the cylinder body 10. The starting point of the outer circumferential extension segment L is on the outer circumference of the cylinder body 10, and its ending point is on the outer circumference of the waist portion 20. The line connecting the starting point and the center of the outer circumference of the cylinder body is a radius p, and the radius p has an angle β with the first reference axis. The value of the angle β is in the range of -15°≤β≤60°. The outer circumferential extension segment L has an angle α with the second reference axis. The value of the angle α is in the range of -15°≤α≤60°. Wherein, when the angle β is below the first reference axis, the angle β is a positive value; when it is above the first reference axis, the angle β is a negative value; when the angle α is outside the second reference axis, the angle α is a positive value; when it is inside the second reference axis, the angle α is a negative value.

[0062] In the above arrangement, the outer circle extension section L is positioned through the included angle α and the included angle β. This defines the extension length of the other end of the reinforcing portion 30. By limiting the included angle α and the included angle β within the above range of values, the position range of the outer circle extension section L is defined, and further the extension length range of the other end of the reinforcing portion 30 is defined. That is, the extension position and shape of the other end of the reinforcing portion 30 are controlled by the set ranges of the included angle α and the included angle β. Limiting the included angle α and the included angle β within the above range can control the deformation amount of the radial sliding vane groove 40 after being completely cut through to be less than 0.23, thereby effectively reducing the deformation amount of the radial sliding vane groove 40.

[0063] It should be noted that the standard requires that the deformation amount of the radial sliding vane groove 40 after being completely cut through is qualified within the range of 0.4. Through tests, the deformation amount of the radial sliding vane groove 40 of mass-produced cylinders in the factory after being completely cut through is about 0.23-0.38, and the radial sliding vane groove 40 is extremely easy to deform. In order to ensure sufficient strength of the waist portion 20 of the cylinder, by verifying different angles of α and β, when α and β are set within the above range of values, the deformation amount of the radial sliding vane groove 40 after being completely cut through is controlled to be less than 0.23, which can better control the deformation amount of the radial sliding vane groove 40.

[0064] Specifically, as shown in Figure 1 , in one embodiment, the value range of the included angle β is 0<β≤60°. The included angle α is formed between the outer circle extension section L and the second reference axis, and the value range of the included angle α is 0<α≤60°. The outer circle extension section L is tangent to the outer circle.

[0065] Specifically, as shown in Figure 1 , in one embodiment, a positioning boss 50 is further included, the positioning boss 50 is disposed on the outer peripheral wall of the cylinder body 10, and is spaced apart from the reinforcing portion 30 along the outer periphery of the cylinder body 10.

[0066] Specifically, as shown in Figure 1 , in one embodiment, the thickness of the reinforcing portion 30 is h, and the thickness of the waist portion 20 is H, wherein the thickness h of the reinforcing portion 30 is equal to the thickness H of the waist portion 20.

[0067] Specifically, as shown in Figure 1 , in one embodiment, the reinforcing portions 30 are respectively disposed at both ends of the waist portion.

[0108] Specifically, such as Figure 9 As shown, in one embodiment, the outer circular extension segment L is an arc segment.

[0109] Specifically, such as Figure 9 As shown, in one embodiment, the starting point of the arc segment is on the outer circle of the cylinder body 10, and the ending point of the arc segment is on the outer circle of the waist 20.

[0110] It should be noted that in this embodiment, since the outer circle extension segment L is an arc segment, the included angle α is not limited, only the starting point of the outer circle extension segment L is limited.

[0111] Example 9 has the same structure as Example 1, and will not be described in detail here.

[0112] Example 10

[0113] Example 10 differs from Example 1 in the following ways:

[0114] Specifically, such as Figure 10 As shown, in one embodiment, the outer circular extension segment L includes a first line segment L1, a second line segment L2, and a third line segment L3.

[0130] Example 12 has the same structure as Example 1, and will not be described in detail here.

[0131] Comparative Example

[0132] like Figure 14 As shown, this invention provides a prior art cylinder for use in a rolling rotor compressor. It includes a cylinder body 10' and a waist section 20'. The cylinder body 10' has a rolling chamber 11' for rolling engagement with the rollers of the rolling rotor compressor. The waist section 20' is located on the outer peripheral wall of the cylinder body 10'. This cylinder, model A098, is already in mass production and widely used.

[0133] Specifically, see Table 1 below and Figure 15 As shown, when the radial sliding groove 40 is completely cut through, the deformation of the radial sliding groove is compared. In the embodiments of the present invention, the radial sliding groove 40 has a deformation of 88.2% less than that of the conventional cylinder in the comparative example. The test can show that the cylinder of this patent can significantly reduce the shrinkage internal stress of the radial sliding groove and effectively reduce the deformation of the radial sliding groove.

[0134] It should be noted that the reinforcing cylinders in Table 1 below are the cylinders in Embodiments 1 to 4 of the present invention.

[0135] Table 1

[0136]

[0137] Specifically, see Figure 16 As shown in Table 2 below, it has been verified that the radial vane groove deformation of the cylinder in Embodiment 7 of the present invention is 87.9% smaller than that of conventional cylinders, which can effectively reduce the deformation of the radial vane groove.

[0138] It should be noted that Scheme 3 in Table 2 below is the scheme of Embodiment 7 above.

[0139] Table 2

[0140]

[0141] Specifically, see Figure 17 As shown in Table 3, the radial sliding groove deformation after wire cutting in Embodiment 9 of the present invention is 88.1% lower than that in the comparative example. Furthermore, it is far below the standard requirement of 0.4 for radial sliding groove deformation. This effectively reduces the radial sliding groove deformation.

[0142] It should be noted that Scheme 1 in the table below is the scheme in Implementation Example 9.

[0143] Table 3

[0144]

[0145] Specifically, see Figure 18 As shown in Table 4, the deformation of the radial sliding groove after wire cutting in Embodiment 10 of the present invention is reduced by 88% compared to the comparative example. This is also far below the standard requirement of 0.4 mm deformation. Therefore, the deformation of the radial sliding groove can be effectively reduced.

[0146] It should be noted that Scheme 2 in the table below is the scheme in Implementation Example 10.

[0147] Table 4

[0148]

[0149] Specifically, see Figure 19 As shown in Table 5, the cylinder in Embodiment 12 of the present invention has a radial vane groove deformation amount that is 87.7% smaller than that of conventional cylinders, which can effectively reduce the radial vane groove deformation amount.

[0150] It should be noted that Scheme 4 in Table 5 below is the scheme in Example 12.

[0151] Table 5

[0152]

[0153] As can be seen from the above, based on the evaluation of the deformation of the sliding groove width, the priority order of schemes 1 to 4 is: scheme 1 > scheme 2 > scheme 3 > scheme 4.

[0154] It should be noted that in the above embodiments, when both included angles α and β are greater than or equal to 0°, the starting point of the outer circle extension segment L is tangent to the outer circle of the cylinder body 10. When both included angles α and β are less than 0°, the starting point of the waist extension can be tangent to or intersect with the waist of the cylinder.

[0155] It should be noted that the values ​​of the included angles α and β depend on the strength of the cylinder waist and the connection strength between the radial vane groove and the waist:

[0156] When the cylinder waist is strong enough, there is no need to further strengthen the waist. In this case, α and β are both 0°, which is the optimal value.

[0157] When the cylinder waist has low strength and needs reinforcement, the design prioritizes α and β angles greater than 0°. Considering weight reduction, the shaded area is removed, and the outer circumference extension L is divided into two segments, L1 and L2. The α and β angle parameters of L1 and L are required to be the same, both greater than 0°. L2 is parallel to the centerline of the cylinder's sliding vane groove, and its distance d is between r and R, i.e., d ~ (r, R). This design is optimal when d = r.

[0158] It should be noted that, in this invention, the center line of the cylinder passing through the center of the radial sliding vane groove is M2.

[0159] When the cylinder waist has low strength and needs reinforcement, weight reduction holes are set on the reinforced part to achieve weight reduction, with both α and β > 0°. In this case, α and β values ​​of 20° are optimal. The weight reduction holes are only used for weight reduction and cost reduction, and their shape is not limited. Their size only needs to meet the connection strength between the waist and the sliding vane groove.

[0160] When α and β < 0°, the starting point of the waist extension (the starting point of the outer circle extension segment L) can be tangent to or intersect with the waist. This design has lower cylinder deformation resistance than when α and β ≥ 0°. However, it can be selected to ensure lightweight design when the strength of the cylinder waist and the connection strength between the sliding vane groove and the waist are sufficient.

[0161] Example 13

[0162] like Figure 13 As shown, the present invention also provides a rolling rotor compressor, which includes a cylinder, rollers 200, and vanes 300 as described in Embodiment 1 above. The rollers 200 are rotatably disposed within the rolling chamber 11 of the cylinder, and the vanes 300 are slidably disposed within the radial vane groove 40 of the cylinder. The rollers 200 roll within the rolling chamber 11 and, in conjunction with the vanes 300, divide the rolling chamber 11 into a low-pressure chamber 111 and a high-pressure chamber 112.

[0163] It should be noted that the working principle of the rolling rotor compressor is existing technology and will not be elaborated here. Of course, depending on the actual situation, the rolling rotor compressor can be configured to include the cylinders in the other embodiments described above.

[0164] Specifically, such as Figure 1 As shown, in one embodiment, the cylinder is used in a rolling rotor compressor and includes a cylinder body 10, a waist portion 20, and a reinforcing portion 30. The cylinder body 10 has a rolling chamber 11 for rolling engagement with the rollers 200 of the rolling rotor compressor. The waist portion 20 is disposed on the outer peripheral wall of the cylinder body 10. The reinforcing portion 30 is disposed on the outer peripheral wall of the cylinder body 10, with one end connected to one end of the waist portion 20 and the other end extending circumferentially along the cylinder body 10. Radial vane grooves 40 communicating with the rolling chamber 11 are provided on the cylinder body 10 and the waist portion 20. The reinforcing portion 30 strengthens the waist portion 20 and the connection between the waist portion 20 and the radial vane groove 40, thereby reducing the deformation of the radial vane groove 40.

[0165] In this embodiment, based on the existing cylinder structure, a reinforcing portion 30 is additionally provided, connected to one end of the waist portion 20 and extending circumferentially along the cylinder body 10 at the other end. The reinforcing portion 30 strengthens the waist portion 20 and the connection strength between the waist portion 20 and the radial sliding groove 40. This significantly reduces the internal stress of cylinder contraction and reduces the deformation of the radial sliding groove 40. Therefore, the deformation of the radial sliding groove 40 is effectively reduced. Specifically, as... Figure 1 As shown, in one embodiment, the other end of the reinforcing portion 30 extends circumferentially along the cylinder body 10 to the outer circumferential extension segment L of the cylinder body 10. The starting point of the outer circumferential extension segment L is on the outer circumference of the cylinder body 10, and its ending point is on the outer circumference of the waist portion 20. The line connecting the starting point and the center of the outer circumference of the cylinder body 10 has a radius p, and it has an angle β with the first reference axis, the value of which is -15°≤β≤60°. The outer circumferential extension segment L has an angle α with the second reference axis, the value of which is -15°≤α≤60°. Wherein, when the angle β is below the first reference axis, the angle β is positive; when it is above the first reference axis, the angle β is negative; when the angle α is outside the second reference axis, the angle α is positive; when it is inside the second reference axis, the angle α is negative.

[0166] In this embodiment, the outer circular extension segment L is positioned using included angles α and β. This defines the extension length of the other end of the reinforcing portion 30. By limiting included angles α and β within the aforementioned range, the position range of the outer circular extension segment L is defined, thereby defining the extension length range of the other end of the reinforcing portion 30. That is, by setting the range of included angles α and β, the extension position and shape of the other end of the reinforcing portion 30 are controlled. Limiting included angles α and β within the aforementioned range allows the deformation of the radial sliding groove 40 after it is completely cut through to be controlled to below 0.23. This effectively reduces the deformation of the radial sliding groove 40.

[0167] Specifically, such as Figure 1 As shown, in one embodiment, the included angle β ranges from 0 to 60°. The outer circular extension L has an included angle α with the second reference axis, and the included angle α ranges from 0 to 60°. The outer circular extension L is tangent to the outer circle.

[0168] Specifically, such as Figure 1 As shown, in one embodiment, a positioning boss 50 is also included. The positioning boss 50 is disposed on the outer peripheral wall of the cylinder body 10 and is spaced apart from the reinforcing part 30 along the outer periphery of the cylinder body 10.

[0169] Specifically, such as Figure 1 As shown, in one embodiment, the thickness of the reinforcing part 30 is h, and the thickness of the waist part 20 is H, wherein the thickness h of the reinforcing part 30 is equal to the thickness H of the waist part 20.

[0170] Specifically, such as Figure 1 As shown, in one embodiment, the reinforcing parts 30 are respectively disposed at both ends of the waist.

[0171] Example 14

[0172] The present invention also provides an air conditioner comprising the above-described rolling rotor compressor.

[0173] Specifically, in one embodiment, the rolling rotor compressor includes the cylinder, rollers 200, and vanes 300 described in Embodiment 1 above. The rollers 200 are rotatably disposed within the rolling chamber 11 of the cylinder, and the vanes 300 are slidably disposed within the radial vane groove 40 of the cylinder. The rollers 200 roll within the rolling chamber 11 and, in conjunction with the vanes 300, divide the rolling chamber 11 into a low-pressure chamber 111 and a high-pressure chamber 112.

[0174] Specifically, such as Figure 1 As shown, in one embodiment, the cylinder is used in a rolling rotor compressor and includes a cylinder body 10, a waist portion 20, and a reinforcing portion 30. The cylinder body 10 has a rolling chamber 11 for rolling engagement with the rollers 200 of the rolling rotor compressor. The waist portion 20 is disposed on the outer peripheral wall of the cylinder body 10. The reinforcing portion 30 is disposed on the outer peripheral wall of the cylinder body 10, with one end connected to one end of the waist portion 20 and the other end extending circumferentially along the cylinder body 10. Radial vane grooves 40 communicating with the rolling chamber 11 are provided on the cylinder body 10 and the waist portion 20. The reinforcing portion 30 strengthens the waist portion 20 and the connection between the waist portion 20 and the radial vane groove 40, thereby reducing the deformation of the radial vane groove 40.

[0175] Specifically, such as Figure 1 As shown, in one embodiment, the other end of the reinforcing portion 30 extends circumferentially along the cylinder body 10 to the outer circumferential extension segment L of the cylinder body 10. The starting point of the outer circumferential extension segment L is on the outer circumference of the cylinder body 10, and its ending point is on the outer circumference of the waist portion 20. The line connecting the starting point and the center of the outer circumference of the cylinder body 10 has a radius p, and it has an angle β with the first reference axis, the value of which is -15°≤β≤60°. The outer circumferential extension segment L has an angle α with the second reference axis, the value of which is -15°≤α≤60°. Wherein, when the angle β is below the first reference axis, the angle β is positive; when it is above the first reference axis, the angle β is negative; when the angle α is outside the second reference axis, the angle α is positive; when it is inside the second reference axis, the angle α is negative.

[0176] In this embodiment, the outer circular extension segment L is positioned using included angles α and β. This defines the extension length of the other end of the reinforcing portion 30. By limiting included angles α and β within the aforementioned range, the position range of the outer circular extension segment L is defined, thereby defining the extension length range of the other end of the reinforcing portion 30. That is, by setting the range of included angles α and β, the extension position and shape of the other end of the reinforcing portion 30 are controlled. Limiting included angles α and β within the aforementioned range allows the deformation of the radial sliding groove 40 after it is completely cut through to be controlled to below 0.23. This effectively reduces the deformation of the radial sliding groove 40.

[0177] Specifically, such as Figure 1 As shown, in one embodiment, the included angle β ranges from 0 to 60°. The outer circular extension L has an included angle α with the second reference axis, and the included angle α ranges from 0 to 60°. The outer circular extension L is tangent to the outer circle.

[0178] Specifically, such as Figure 1 As shown, in one embodiment, a positioning boss 50 is also included. The positioning boss 50 is disposed on the outer peripheral wall of the cylinder body 10 and is spaced apart from the reinforcing part 30 along the outer periphery of the cylinder body 10.

[0179] Specifically, such as Figure 1 As shown, in one embodiment, the thickness of the reinforcing part 30 is h, and the thickness of the waist part 20 is H, wherein the thickness h of the reinforcing part 30 is equal to the thickness H of the waist part 20.

[0180] Specifically, such as Figure 1 As shown, in one embodiment, the reinforcing parts 30 are respectively disposed at both ends of the waist.

[0181] It should be noted that other specific structures and working principles of air conditioners are existing technologies and will not be elaborated here.

[0182] Although the invention has been described with reference to preferred embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict.
