Abstract
Description
Technical Field
[0001] This invention relates to the field of kitchen equipment technology, and in particular to a control method for the air inlet flap of an integrated stove and the integrated stove itself. Background Technology
[0002] To prevent external odors and pollutants from flowing back into the kitchen when the range hood of an integrated cooktop is not in use, an automatically opening and closing flap is typically installed at the air inlet. When the cooktop is in operation, this flap opens to expel cooking fumes; when the cooktop is off, the flap closes to prevent external odors from entering the kitchen. The opening and closing of this flap is usually controlled by a drive motor, and this process is typically automated. That is, after the user turns the range hood on or off, the program controls the drive motor to automatically perform the flap's actions. Current technology uses relatively simple flap control methods and cannot adapt to the current cooking environment. Summary of the Invention

[0056] Figure 1 This is a schematic diagram of the structure of an integrated stove provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of another integrated stove provided in an embodiment of the present invention. Figure 1 The image shown is a schematic diagram of the physical structure of an integrated stove. Figure 2 This is a schematic diagram of the electrical connections for an integrated stove. (For reference only) Figure 1 and Figure 2 The integrated stove includes an air inlet 1, an air inlet flap 2, a detector 3, and a control device 4. The air inlet flap 2 covers the air inlet 1, and the detector 3 is used to detect the appearance parameters of the cookware 5. The control device 4 is electrically connected to the air inlet flap 2 and the detector 3 respectively. Figure 3 This is a flowchart illustrating a control method for an integrated stove air inlet flap according to an embodiment of the present invention. This method can be used to adjust the state of the air inlet flap 2 at the air inlet 1 of the integrated stove. This method can be executed by a control device 4 within the integrated stove, which can be implemented by software and / or hardware and is generally integrated into the integrated stove. Figures 1-3 As shown in the figure, an embodiment of the present invention provides a method for controlling the air inlet flap of an integrated stove, comprising the following steps:
[0057] S110. Obtain the appearance parameters of the cookware based on the detector.
[0058] Among them, reference Figure 1 and Figure 2 The detector 3 can be positioned above the burner (including directly above and to the side), and the cookware 5 is placed above the burner during cooking. The detector 3 is used to collect the appearance parameters of the cookware 5, which may include, but are not limited to, the cookware height and dimensions. The cookware dimensions mentioned here may refer to the area of the cookware opening and / or the volume of the cookware body. The detector 3 collects the appearance parameters of the cookware 5 and sends them to the control device 4.
[0059] Optionally, the detector 3 can be a lidar, infrared detector, or ultrasonic detector, etc. This embodiment of the invention does not limit this; any instrument capable of detecting the appearance parameters of the cookware is within the scope of the technical solution protected by this embodiment. Furthermore, a typical integrated stove includes two burners, and the detector 3 can simultaneously detect the appearance parameters of the cookware 5 placed on both burners.
[0060] Optionally, the detector 3 and the control device 4 can be connected via a data transmission unit 6, which processes the data detected by the detector 3 and then transmits it to the control device 4.
[0061] S120. Adjust the working status of the air inlet flap according to the appearance parameters.
[0062] Furthermore, those skilled in the art will understand that the opening angle of the air inlet flap 2 corresponds to the opening area of the air inlet 1. When the air inlet flap 2 is closed, the air inlet flap 2 completely covers the air inlet 1, and the flue is not connected to the kitchen environment. The larger the opening angle of the air inlet 1, the larger the opening area of the air inlet 1, and the larger the area connected to the kitchen environment, that is, the larger the smoke collection area. After the air inlet flap 2 is opened, the range hood works to draw water vapor and / or oil fumes generated during the cooking process into the air inlet 1, and then exhaust them through the flue.
[0063] In this embodiment of the invention, the working state of the air inlet flap 2 may include the air inlet flap 2 being open, the air inlet flap 2 being closed, and the opening angle of the air inlet flap 2. After receiving the appearance parameters of the cookware, the control device 4 can adjust the working state of the air inlet flap 2 in combination with the appearance parameters so that the working state of the air inlet flap 2 matches the appearance of the cookware 5 currently being used, or in other words, matches the current cooking environment, thereby realizing intelligent control of the air inlet flap 2.
[0064] The control device 4 can be electrically connected to the air inlet flap 2 via a drive motor, and the air inlet flap 2 can be opened and closed by controlling the drive motor. Alternatively, the air inlet flap 2 can be an electric flap, and the control device 4 can be directly electrically connected to the air inlet flap 2 and control the opening and closing of the air inlet flap 2.
[0065] In this embodiment of the invention, the integrated stove includes an air inlet, an air inlet flap, a detector, and a control device. The air inlet flap covers the air inlet, and the detector is used to detect the appearance parameters of the cookware. The control device is electrically connected to both the air inlet flap and the detector. The control method for the integrated stove's air inlet flap includes: acquiring the appearance parameters of the cookware based on the detector; and adjusting the working state of the air inlet flap according to the appearance parameters. Through the above scheme, the control device can adjust the working state of the air inlet flap based on the appearance parameters of the cookware being used, so that the working state of the air inlet flap matches the appearance of the currently used cookware, or in other words, matches the current cooking environment, thereby achieving intelligent dynamic control of the air inlet flap and improving the fume extraction effect.
[0066] Based on the above embodiments, the present invention proposes several optional embodiments. In the detailed embodiments, the structure of the integrated stove can still refer to... Figure 1 and Figure 2 .
[0067] For example, in some optional embodiments, the detector 3 includes a lidar 31, which is positioned above the cookware 5. The appearance parameters include the cookware height and the cookware opening size, where the opening size is the horizontal dimension of the cookware opening. The horizontal direction is the direction of the plane where the cookware panel is located. The above (S110) can be further refined to: S210, obtaining the cookware height and cookware opening size based on the lidar; (S120) can be further refined to: S220, adjusting the opening angle of the air inlet flap according to the cookware height and cookware opening size.
[0068] Figure 4 A flowchart illustrating another control method for the air inlet flap of an integrated stove provided in an embodiment of the present invention is shown below. Figure 1 , Figure 2 and Figure 4 The control method includes the following steps:
[0069] S210. The height of the cookware and the opening size of the cookware are obtained based on lidar.
[0070] Specifically, the lidar 31 can determine the three-dimensional coordinates and shape of an object by emitting a laser beam towards it and receiving the reflected light. In this embodiment of the invention, the lidar 31 is integrated into an integrated stove, and the lidar 31 is used to collect the appearance parameters of the cookware 5.
[0071] The number and deployment location of the lidar 31 are not limited, and those skilled in the art can set them according to actual needs. This embodiment of the invention does not limit this. Figure 1 The example shows two lidars 31, which are respectively set on both sides of the air inlet 1 and collect the appearance parameters of the pot 5 below. The actual situation is not limited to this.
[0072] It should be noted that the detection range S (or radiation range) of the lidar 31 should cover the area where the cookware 5 is located. For example, the radiation range of the left lidar 31 (the multiple curves covering the cookware 5 shown in the figure represent the radiation range of the lidar 31) can be set to cover the left side of the cookware, and the radiation range of the right lidar 31 can cover the right side of the cookware, thereby ensuring accurate detection of the appearance parameters of the cookware 5.
[0073] The lidar 31 can be used to collect the height of the cookware and the size of its opening. The height of the cookware is the overall vertical dimension of the cookware 5, and the size of the opening refers to the area covered by the opening in the horizontal direction. The opening is the area inside the cookware where food is placed. It is understood that cooking fumes (including steam) will be generated at the opening of the cookware. The lidar 31 sends the collected cookware height and opening size parameters to the control device 4.
[0074] S220. Adjust the opening angle of the air inlet flap according to the height of the cookware and the size of the cookware opening.
[0075] Figure 5 This is a schematic diagram illustrating the working state of an air inlet flap according to an embodiment of the present invention. Figure 5 The image shown is a side view of the integrated stove, for reference. Figure 5 When the height and opening size of the cookware differ, the coverage area of the steam and / or fumes generated during cooking varies. Correspondingly, to ensure that both steam and / or fumes can enter the air inlet 1, the opening angle of the air inlet flap 2 varies. Generally, the larger the cookware height and opening size, the larger the opening angle of the air inlet flap 2. In this way, the opening area of the air inlet 1 matches the actual amount of fumes generated, ensuring effective fume extraction while reducing the area requiring negative pressure at the air inlet 1, thus lowering the noise level of the range hood.
[0076] Optional, you can continue to refer to Figure 1 and Figure 5 In some embodiments, the air inlet 1 is located on the back panel 7 of the integrated stove; after the above (S210), the following steps can also be performed: Step 1: Determine the position point of the far edge of the pot on the side of the pot opening away from the back panel according to the height of the pot and the size of the pot opening; the above (S220) can be further refined as: Step 2: Determine the target opening angle of the air inlet flap according to the position point of the far edge of the pot; Step 3: Control the rotation of the air inlet flap according to the target opening angle.
[0077] like Figure 1 and Figure 5As shown, the air inlet 1 is located on the back panel 7 of the integrated stove, which extends vertically. The pivot of the air inlet flap 2 is parallel to the back panel 7 and extends horizontally. When the range hood is not working, the air inlet flap 2 is placed vertically and covers the air inlet 1; when the range hood is working, the pivot of the air inlet flap 2 is rotated, causing the air inlet flap 2 to be raised to a certain angle with the back panel 7, thus opening the air inlet 1.
[0078] Continue to refer to Figure 5 After the air inlet flap 2 is raised, the space between the plane of the air inlet flap 2 and the back plate 7 is the smoke collection area Q. To ensure that all the oil fumes generated in the pot opening during cooking enter the air inlet 1, in this embodiment, the target opening angle θx of the air inlet flap 2 can be determined according to the position point 8 of the far edge of the pot. The position point 8 of the far edge of the pot refers to the edge point of the pot opening away from the back plate 7. When the position point 8 of the far edge of the pot is located within the smoke collection area Q, the oil fumes generated by the pot 5 can basically enter the air inlet 1.
[0079] Specifically, the control device 4 can determine the position point 8 of the far edge of the pot based on the pot height and the pot opening size. It is understandable that, since the relative positions of the burner and the lidar 31 in the integrated stove are fixed, the position point 8 of the far edge of the pot can be calculated based on geometric relationships if the pot height and the pot opening size are known. Alternatively, before using the integrated stove, staff can obtain the position points 8 of the far edge of pots 5 corresponding to different sizes through testing and / or simulation, and then establish a mapping table of the relative relationships between the pot height, the pot opening size, and the position point 8 of the far edge of the pot. When the integrated stove is in use, the position point 8 of the far edge of the pot is determined by looking up the table based on the collected pot height and pot opening size.
[0080] The distal edge position point 8 of the cookware described in this embodiment of the invention may include the coordinates of the position point in the horizontal and / or vertical directions. After the distal edge position point 8 of the cookware is determined, the target opening angle θx of the air inlet flap 2 is selected according to the distal edge position point 8, and the air inlet flap 2 is rotated to the target opening angle θx. When the air inlet flap 2 is rotated to the target opening angle θx, the distal edge position point 8 of the cookware is located in the space between the plane of the air inlet flap 2 and the back plate 7, so as to better increase the coverage area of the smoke collection area Q and ensure the best smoke extraction effect.
[0081] For example, the control device 4 can store the correspondence between the position point 8 of the far edge of the cookware and the opening angle of the air inlet flap 2. Once the position point 8 of the far edge of the cookware is determined, the target opening angle corresponding to the current position point 8 of the far edge of the cookware can be determined by looking up a table.
[0082] Optional, Figure 6This is a schematic diagram illustrating another working state of the air inlet flap provided in an embodiment of the present invention. (See attached diagram.) Figure 6 When the air inlet flap 2 rotates to the target opening angle θx, the intersection point A of the virtual extension line 21 of the air inlet flap 2 and the plane where the pot opening is located is located on the outer side of the side wall of the pot opening away from the back plate 7; the virtual extension line 21 is the virtual extension line of the air inlet flap 2 in the first direction X, the first direction X is parallel to the plane where the air inlet flap 2 is located and perpendicular to the rotation axis 22 of the air inlet flap 2.
[0083] Specifically, the intersection of the virtual extension line 21 of the air inlet flap 2 and the plane where the pot opening is located can be defined as the first intersection point A. In this embodiment, the first intersection point A can be set to be located on the outer side wall of the side of the pot opening away from the back plate 7. That is, the straight-line distance between the first intersection point A and the back plate 7 is greater than the distance between the far edge position point 8 of the pot and the back plate 7. In this way, it can be ensured that after the air inlet flap 2 is rotated to the target opening angle θx, the far edge position point 8 of the pot is located in the space between the plane where the air inlet flap 2 is located and the back plate 7.
[0084] Figure 5 In the embodiment shown, when the air inlet flap 2 is rotated to the target opening angle θx, the intersection point A of the virtual extension line 21 of the air inlet flap 2 and the plane where the pot opening is located coincides with the far edge position point 8 of the pot, and the far edge position point 8 of the pot coincides with the smoke collection area Q.
[0085] Further optionally, in possible embodiments, the above (step two) can be further refined into the following sub-steps one to three. Sub-step one: Determine the preset opening angle of the air inlet flap based on the position point of the far edge of the pot; such as... Figure 6 As shown, when the air inlet flap 2 rotates to the preset opening angle θ0, the intersection point A of the virtual extension line 21 of the air inlet flap 2 and the plane where the pot opening is located coincides with the side wall of the pot opening away from the back panel 7; the virtual extension line 21 is the virtual extension line of the air inlet flap 2 in the first direction X, which is parallel to the plane where the air inlet flap 2 is located and perpendicular to the rotation axis 22 of the air inlet flap 2. Sub-step two: Determine the correction angle according to the working state of the integrated stove; Sub-step three: Use the sum of the preset opening angle and the correction angle as the target opening angle.
[0086] Specifically, please refer to Figure 6In this embodiment, in the correspondence between the far edge position point 8 of the cookware and the opening angle of the air inlet flap 2 stored in the control device 4, when the air inlet flap 2 rotates to the opening angle corresponding to a certain far edge position point 8 of the cookware, the first intersection point A of the virtual extension line 21 of the air inlet flap 2 on the plane where the cookware opening is located coincides with the side wall of the cookware opening away from the back plate 7. That is, the first intersection point A coincides with the far edge position point 8 of the cookware, or it can be interpreted as the straight distance between the first intersection point A and the back plate 7 being equal to the straight distance between the far edge position point 8 of the cookware and the back plate 7.
[0087] In sub-step one, after the position point 8 at the far edge of the cookware is determined, the opening angle of the air inlet flap 2 corresponding to the position point 8 can be determined first, and the opening angle of the air inlet flap 2 is used as the preset opening angle θ0. When the air inlet flap 2 rotates to the preset opening angle θ0, the smoke collection area Q just covers the position point 8 at the far edge of the cookware.
[0088] Furthermore, this embodiment also proposes that, in order to ensure that the virtual extension line 21 of the air inlet flap 2 can completely cover the far edge position point 8 of the cookware, a correction angle θy can be added. The correction angle θy and the preset opening angle θ0 are added together to obtain the target opening angle θx. It can be understood that the correction angle θy should be greater than or equal to 0°. After increasing the correction angle θy, the coverage area of the smoke collection area Q can be increased better, thereby achieving a better smoke extraction effect.
[0089] One noteworthy point is that in sub-step two, the correction angle can be determined based on the current operating status of the integrated stove, which reflects the concentration of cooking fumes generated during the cooking process. In this embodiment, selecting a suitable correction angle θy based on the operating status of the integrated stove ensures optimal fume extraction while avoiding power waste and excessive noise caused by an excessively large negative pressure area.
[0090] Optionally, the integrated cooktop also includes a range hood and a cooktop assembly, which are electrically connected to the control device respectively; the above (sub-step two) can be further refined into: sub-step three, determining the correction angle by combining the range hood's gear information and the cooktop assembly's firepower information.
[0091] The range hood is located above the cooktop assembly, which includes burners and other components. As an optional embodiment, the integrated cooktop's operating status includes both the range hood's operating status and the cooktop assembly's operating status. The range hood's operating status includes its setting information, i.e., its actual operating setting. The cooktop assembly's operating status includes its heat output information, i.e., its operating heat output.
[0092] Generally, the higher the operating speed of a range hood, the greater its power and the higher the negative pressure at the air inlet; similarly, the higher the heat output of the cooktop components, the greater the concentration of cooking fumes. To ensure effective fume extraction, the opening area of the air inlet may vary depending on the operating speed of the range hood and the heat output of the cooktop components. This opening area is determined by the opening angle of the air inlet flap. Therefore, in this embodiment, a correction angle θy can be determined based on the actual operating speed of the range hood and the actual heat output of the cooktop components, so that the opening area of the air inlet corresponding to the corrected target opening angle matches the actual cooking environment.
[0093] Optionally, the control device can pre-store the corresponding relationship between the range hood's power setting, the cooktop's firepower information, and the correction angle θy. This relationship can be established by staff through testing or simulation before the integrated cooktop is put into use. After determining the power setting and firepower information, the correction angle θy is determined using a lookup table method.
[0094] Optionally, the above (sub-step three) can be further refined as follows: when the gear information is strong and the firepower information is strong, determine the first correction angle θ1; when the gear information is strong and the firepower information is weak, determine the second correction angle θ2; when the gear information is weak and the firepower information is weak, determine the third correction angle θ3; when the gear information is weak and the firepower information is strong, determine the fourth correction angle θ4; wherein, θ1 > θ3 > θ4 > θ2.
[0095] Specifically, when both the range hood and cooktop are running at their highest settings, the concentration of cooking fumes is high, and the range hood's power is also high. In this case, a larger angle (i.e., the first correction angle θ1) can be used to increase the opening area of the air inlet and improve the fume collection area. When the range hood is running at its highest setting and the cooktop is running at its lowest setting, the concentration of cooking fumes is low, and the range hood's power is still high. The range hood can provide sufficient negative pressure to expel the fumes. In this case, the second correction angle θ2 can be 0°, and controlling the air inlet flap to rotate to the preset opening angle θ0 will ensure effective fume extraction. When both the range hood and cooktop are running at their lowest settings, the concentration of cooking fumes is low, and the range hood's power is also low. In this case, a smaller angle (i.e., the third correction angle θ3) can be used to appropriately reduce the opening area of the air inlet and increase the air intake speed. When the range hood is running at a low setting and the cooktop is running at a high setting, the oil fume concentration is high and the range hood power is low. In this case, a smaller angle should be used as the correction angle (fourth correction angle θ4). While ensuring that the smoke collection area covers the far edge of the cookware, the opening area of the air inlet should be minimized as much as possible to increase the air intake speed and ensure the oil fume removal effect.
[0096] In this embodiment of the invention, the specific values of the first correction angle θ1, the second correction angle θ2, the third correction angle θ3, and the fourth correction angle θ4 are not limited, and those skilled in the art can set them according to actual needs. Figure 7 A matrix diagram for correcting angles is provided in an embodiment of the present invention, such as... Figure 7 As shown, when both the range hood and the cooktop are running at high speed, the first correction angle θ1 is taken from the first quadrant; when the range hood is running at high speed and the cooktop is running at low speed, the second correction angle θ2 is taken from the second quadrant; when the range hood is running at low speed and the cooktop is running at low speed, the third correction angle θ3 is taken from the third quadrant; and when the range hood is running at low speed and the cooktop is running at high speed, the fourth correction angle θ4 is taken from the fourth quadrant.
[0097] Additionally, it should be noted that the "strong" and "weak" settings of the range hood proposed in this embodiment are relative settings. Assuming the range hood has four operating settings, the two higher power settings can be considered as the "strong" setting, and the two lower power settings as the "weak" setting. The same principle applies to the division of "strong" and "weak" settings for the cooktop assembly.
[0098] Optionally, in a possible embodiment, before the above (S220), the following steps may also be performed: determining the obstruction status of the air inlet flap based on the height of the cookware; when it is determined that the cookware does not obstruct the air inlet flap, controlling the air inlet flap to open normally; when it is determined that the cookware obstructs the air inlet flap, controlling the air inlet flap to remain closed.
[0099] Specifically, Figure 8 This is a schematic diagram illustrating another working state of the air inlet flap provided in an embodiment of the present invention, as shown below. Figure 8 As shown, if the pot 5 used is too high, the pot 5 may block the running trajectory B of the air inlet flap 2. If the air inlet flap 2 is still controlled to perform the opening and closing action, the air inlet flap 2 may be damaged or the air inlet flap 2 may tip over the pot, which poses a certain safety hazard.
[0100] Based on this, this embodiment proposes that before controlling the rotation of the air inlet flap 2, the control device 4 can detect the height of the cookware using lidar and determine whether the currently used cookware 5 will obstruct the opening and closing of the air inlet flap 2 based on the detected cookware height. If it is determined that the cookware 5 will not obstruct the opening and closing of the air inlet flap 2, the subsequent control operation of the air inlet flap 2 can be executed normally; if it is determined that the cookware 5 will obstruct the opening and closing of the air inlet flap 2, the subsequent control operation of the air inlet flap 2 will not be executed, so that the air inlet flap 2 remains in a closed state to avoid safety issues.
[0101] Optionally, the above (judging the obstruction of the air inlet flap based on the height of the cookware) can be further refined as follows: when the height of the cookware is less than or equal to the height threshold, it is determined that the cookware does not obstruct the air inlet flap; when the height of the cookware is greater than the height threshold, it is determined that the cookware obstructs the air inlet flap.
[0102] Specifically, the control device can pre-store a height threshold, which is the height limit of the cookware. When the height of the cookware is detected to exceed the height threshold, it is determined that the cookware is too tall, which will affect the opening and closing action of the air inlet flap. When the height of the cookware is detected not to exceed the height threshold, it is determined that the cookware is not too tall, and it will not affect the opening and closing action of the air inlet flap.
[0103] The specific value of the height threshold is related to the design and size of the integrated stove, and this embodiment of the invention does not limit it.
[0104] Further optionally, in some embodiments, after the above (determining the obstruction of the air inlet flap based on the height of the cookware), the following can also be performed: when it is determined that the cookware is obstructing the air inlet flap, an alarm reminder can be issued.
[0105] Specifically, when it is determined that the cookware will affect the normal opening and closing of the air inlet flap, the control device can issue an alarm through the alarm unit, which may include, but is not limited to, an audio alert. Simultaneously, the control device can also display the alarm information on the integrated stove's display unit, indicating to the user that the cookware is too high. The display unit can be the integrated stove's display panel.
[0106] Figure 9 The control logic diagram of the control method for the air inlet flap of an integrated stove provided in this embodiment of the invention can be referred to. Figure 9 First, the integrated stove is turned on. Then, the LiDAR sensor performs detection, and the control device obtains the height and opening size of the pot based on the LiDAR detection results. Further, the control device determines whether the pot height is greater than a height threshold. If the pot height is greater than the height threshold, it is determined that the pot is obstructing the air inlet flap, and the alarm unit sounds an alarm, while the display unit shows the alarm information. If the pot height is less than or equal to the height threshold, it is determined that the pot is not obstructing the air inlet flap, and the opening angle of the air inlet flap is automatically adjusted. The method for determining the opening angle of the air inlet flap is the same as in the above embodiment and will not be repeated here.
[0107] The integrated stove provided in the embodiments of the present invention may also include any component structure known to those skilled in the art, which will not be described in detail or limited here.
[0108] Based on the same concept, this invention also provides an integrated stove, which can be further referenced. Figure 1 and Figure 2The integrated stove includes an air inlet 1, an air inlet flap 2, a detector 3, and a control device 4. The air inlet flap 2 covers the air inlet 1, and the detector 3 is used to detect the appearance parameters of the cookware. The control device 4 is electrically connected to the air inlet flap 2 and the detector 3 respectively. The control device 4 is used to execute the control method of the integrated stove air inlet flap provided in any embodiment of the present invention.
[0109] Through the above scheme, the control device can adjust the working state of the air inlet flap according to the appearance parameters of the cookware being used, so that the working state of the air inlet flap matches the appearance of the cookware being used, or in other words, matches the current cooking environment, thereby realizing intelligent control of the air inlet flap.
[0110] Optional, continue to refer to Figure 1 and Figure 2 In some embodiments, the detector 3 includes a lidar 31, which is positioned above the cookware 5 and has a detection range covering the area where the cookware 5 is located.
[0111] Optional, continue to refer to Figure 1 and Figure 2 The integrated stove may also include an alarm unit 9 and a display unit 10, and the control device 4 is electrically connected to the alarm unit 9 and the display unit 10 respectively. When it is determined that the cookware 5 will affect the normal opening and closing of the air inlet flap 2, the control device 4 can issue an alarm reminder through the alarm unit 9, which may include, but is not limited to, an audio reminder; at the same time, the control device 4 can also display alarm reminder information through the integrated stove's display unit 10 to remind the user that the cookware is too high.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention.
