[0060] The following is combined with Figures 1-9, the door body assembly and refrigeration equipment provided by the utility model embodiment are described in detail through specific embodiments and their application scenarios.

[0061] In the first aspect, Figure 1 and Figure 2 As shown, the utility model provides a door assembly, which is applied to refrigeration equipment, including: a box door 1, a cabinet door 2, a sliding module 4 and a hanging structure 5;

[0062] The cabinet door 1 is rotatably arranged on the cabinet body 3 of the refrigeration equipment through at least two hinges 9, and the cabinet door 2 is arranged on the side of the cabinet door 1 away from the cabinet body 3; the sliding module 4 includes a slide rail 41 and a sliding member 42, the slide rail 41 is arranged on the cabinet door 1 and extends along the width direction of the cabinet door 1; the sliding member 42 is movably arranged on the slide rail 41; the hanging structure 5 includes a supporting member 51, a hanging member 52 and a locking member 53, the supporting member 51 is arranged on the sliding member 42, the hanging member 52 is configured to be arranged on the cabinet door 2, and is movably hung on the supporting member 51 along the width direction; the locking member 53 is locked between the supporting member 51 and the hanging member 52 to limit the installation position of the hanging member 52 relative to the supporting member 51 along the width direction;

[0063] Among them, the thickness of the cabinet door 1 is 18-60mm, for example, the thickness of the cabinet door 1 can be 18mm, 25mm, 35mm, 50mm, 55mm or 60mm; the thickness of the cabinet door 2 is 12-26mm, for example, the thickness of the cabinet door 2 can be 12mm, 15mm, 20mm or 26mm.

[0064] It is understandable that the door assembly is applied to refrigeration equipment such as refrigerators and freezers, and a hinge 9 is provided on the box body 3 of the refrigeration equipment, and the box door 1 is rotatably connected to the box body 3 through the hinge 9 to realize the opening or closing of the box door 1 relative to the box body 3. The outer side of the box door 1 is provided with a cabinet door 2, which can be a door panel, and the cabinet door 2 and the surrounding cabinets can be made of the same material to ensure that the appearance of the refrigeration equipment is consistent with the surrounding cabinets, so that the refrigeration equipment is better coordinated with the surrounding environment.

[0065] For the sliding module 4, the slide rail 41 may be a C-shaped guide rail, the sliding member 42 may be a sliding block, and at least a portion of the sliding member 42 may be movably disposed in a slide groove of the C-shaped guide rail along an extension direction of the C-shaped guide rail.

[0066] For the hanging structure 5, the hanging member 52 is detachably mounted on the cabinet door 2 by fasteners such as bolts and rivets, and the supporting member 51 can be detachably mounted on the sliding member 42 by fasteners, or can be set as an integrated structure with the sliding member 42; the supporting member 51 can be provided with hanging structures such as hanging grooves and bayonet slots, so that the hanging member 52 can be quickly and reliably hung on the hanging structure under the action of gravity of the cabinet door 2, and can move relative to the supporting member 51 along the width direction.

[0067] Furthermore, the locking member 53 can be a bolt, a locking pin, a magnetic attraction member, etc. well-known in the art. After the installation position of the hanging member 52 relative to the supporting member 51 is adjusted, the hanging member 52 and the supporting member 51 can be connected into one body through the locking member 53 to prevent the hanging member 52 from moving relative to the supporting member 51.

[0068] As can be seen from the above, by providing the sliding module 4 and the hanging structure 5 between the cabinet door 1 and the cabinet door 2, the sliding module 4 includes a sliding rail 41 and a sliding member 42 arranged in a sliding manner. When installing the cabinet door 2, the sliding rail 41 of the sliding module 4 can be connected to the cabinet door 1 to realize the installation of the sliding module 4. Then, the supporting member 51 is installed on the sliding member 42 of the sliding module 4, and the hanging member 52 is installed on the cabinet door 2. By hanging the hanging member 52 on the supporting member 51, the installation of the cabinet door 2 can be quickly realized; then, the installation position of the hanging member 52 relative to the supporting member 51 is adjusted in the width direction, and the relative position of the hanging member 52 and the supporting member 51 is locked by the locking member 53, so as to conveniently realize the adjustment of the installation position of the cabinet door 2 relative to the cabinet door 1 in the width direction. This cabinet door installation method is easy to operate and can adjust the hanging position of the cabinet door 2 relative to the cabinet door 1 according to actual needs, which not only reduces the labor intensity of the installers, but also improves the installation efficiency of the cabinet door.

[0069] Furthermore, in practical applications, when the refrigeration equipment is installed in an embedded manner relative to the cabinet, during the process of opening or closing the cabinet door 1, the cabinet door 2 can be moved relative to the cabinet door 1 in the width direction, so as to avoid the cabinet door 2 touching the surrounding cabinets during the opening and closing process of the cabinet door 1, meeting the normal opening and closing requirements of the cabinet door 1 of the refrigeration equipment.

[0070] In some embodiments, as Figure 2 and Figure 3 shown, the supporting member 51 is provided with a hanging hole 5101, and the hanging member 52 is movably inserted through the hanging hole 5101 in the width direction and is hung on the supporting member 51 based on the hanging hole 5101.

[0071] It can be understood that the opening shape of the hanging hole 5101 can be circular, rectangular, waist-shaped, oval, etc. The width of the hanging hole 5101 extending in the width direction is greater than the width of the hanging member 52 extending in the width direction. When the hanging member 52 is inserted through the hanging hole 5101, it can move relative to the supporting member 51 in the width direction, thereby changing the hanging position of the hanging member 52 relative to the supporting member 51 in the width direction.

[0072] At the same time, when the hanging member 52 is inserted through the hanging hole 5101, at least part of the hanging member 52 is supported on the upper side of the supporting member 51, so as to ensure that the hanging member 52 is hung on the supporting member 51 based on the hanging hole 5101 and can be used to support the cabinet door 2 connected thereto.

[0073] In practical applications, to facilitate locking the hanging member 52 to the supporting member 51 using the locking member 53, the locking member 53 can be configured to extend along the height direction of the cabinet door 1 or the cabinet door 2.

[0074] In some embodiments, such as Figure 3 and Figure 4 shown, the hanging hole 5101 is a strip-shaped hole that extends along the width direction. The strip-shaped hole is used to guide the movement of the hanging member 52 relative to the supporting member 51 along the width direction.

[0075] It can be understood that the width of the strip-shaped hole extending along the width direction is greater than the width of the hanging member 52 extending along the width direction. The opening width of the strip-shaped hole along the thickness direction of the cabinet door 2 is adapted to the thickness of a part of the hanging member 52 passing through the strip-shaped hole. Thus, the hanging position of the hanging member 52 relative to the supporting member 51 can only be adjusted along the width direction, and the hanging member 52 cannot move relative to the supporting member 51 along the thickness direction.

[0076] In some embodiments, such as Figure 4 、 Figure 5 and Figure 6 shown, the hanging member 52 includes: a hook 521 and a fixing seat 522; the hook 521 passes through the hanging hole 5101 and is hung on the supporting member 51; the fixing seat 522 is connected to the hook 521 and is configured to be detachably connected to the cabinet door 2.

[0077] It can be understood that the hook 521 and the fixing seat 522 can be an integral structure. For example, the hook 521 and the fixing seat 522 form an integral metal hanging part or an integral plastic hanging part.

[0078] The hook 521 is in a hook shape and is vertically downwardly hung on the supporting member 51. Among them, one end of the hook 521 passes through the hanging hole 5101, and the other end of the hook 521 is connected to the fixing seat 522.

[0079] The fixing seat 522 can be detachably mounted on the cabinet door 2 through fasteners such as bolts and rivets.

[0080] Optionally, the fixing seat 522 is provided with mounting holes, and the fixing seat 522 is mounted on the cabinet door 2 through fasteners passing through the mounting holes.

[0081] Optionally, such as Figure 1 and Figure 5As shown, the mounting holes include a circular hole and an oblong hole. The oblong hole extends along the height direction of the cabinet door 2. The diameter of the circular hole is adapted to the diameter of the fastener. The width of the oblong hole extending along the width direction is adapted to the diameter of the fastener, and the length of the oblong hole extending along the height direction is greater than the diameter of the fastener. Thus, based on the oblong hole, the mounting position of the hanging member 52 relative to the cabinet door 2 can be adjusted along the height direction, and further the mounting height of the cabinet door 2 relative to the box door 1 can be adjusted.

[0082] Furthermore, two circular holes can be provided. The two circular holes are arranged on both sides of the oblong hole along the width direction.

[0083] In some embodiments, as Figure 5 shown, in order to reliably hang the hanging member 52 on the supporting member 51, the hook 521 includes a hook head 5211, a hanging portion 5212 and a connecting portion 5213; the hook head 5211, the hanging portion 5212, the connecting portion 5213 and the fixing seat 522 are connected in sequence. The hook head 5211 passes through the hanging hole 5101, and the hanging portion 5212 is configured to be supported on the supporting member 51.

[0084] Among them, the hook head 5211 can be configured to extend along the height direction of the cabinet door 2. The hanging portion 5212 is arranged horizontally and is perpendicular to the hook head 5211. The connecting portion 5213 can be configured as an "L" - shaped structure. One end of the connecting portion 5213 is connected to the hanging portion 5212, and the other end of the connecting portion 5213 is connected to the fixing seat 522.

[0085] In some embodiments, as Figure 3 shown, the supporting member 51 includes: a bottom plate 511 and at least one side plate 512. The bottom plate 511 is connected to the sliding member 42, and a hanging hole 5101 is provided on the bottom plate 511; at least one side plate 512 is respectively connected to the bottom plate 511 and the sliding member 42.

[0086] Specifically, in the case where the hook 521 includes a hook head 5211, a hanging portion 5212 and a connecting portion 5213, the hook head 5211 passes through the hanging hole 5101 on the bottom plate 511, and the hanging portion 5212 is arranged on the bottom plate 511, and the hanging portion 5212 is supported by the bottom plate 511. Based on this setting, the hanging member 52 is hung on the supporting member 51.

[0087] At the same time, since the bottom plate 511 is connected to the sliding member 42 through the side plate 512, the side plate 512 functions as a reinforcing rib, which can enhance the bonding strength between the bottom plate 511 and the sliding member 42, and ensure that the hanging member 52 is preferably supported by the bottom plate 511.

[0088] Among them, the bottom plate 511 can be set to extend along the width direction, and two side plates 512 can be provided. The two side plates 512 are arranged at both ends of the bottom plate 511 along the width direction.

[0089] In some embodiments, such as Figure 3 , Figure 4 and Figure 5 shown, the locking member 53 includes a locking bolt, and the supporting member 51 is provided with an adjusting hole 5102; the nut of the locking bolt is limited to one side of the supporting member 51, and the screw rod of the locking bolt is movably inserted through the adjusting hole 5102 in the width direction and is threadedly connected to the hanging member 52.

[0090] It can be understood that the adjusting hole 5102 can be provided on the bottom plate 511 of the supporting member 51, the adjusting hole 5102 can be an oblong hole, and is configured to extend along the width direction of the cabinet door 1; a threaded hole 5201 can be provided on the hanging member 52, for example, the threaded hole 5201 is provided on the hanging portion 5212 of the hanging member 52.

[0091] In practical applications, the screw rod of the locking bolt can be vertically inserted through the adjusting hole 5102 in the direction from bottom to top, and then preliminarily connected to the threaded hole 5201 on the hanging member 52; after the installation position of the hanging member 52 relative to the supporting member 51 in the width direction is adjusted, the locking bolt is then screwed until the locking bolt locks the hanging member 52 and the supporting member 51 together to prevent the hanging member 52 from moving relative to the supporting member 51.

[0092] In some embodiments, such as Figure 3 shown, the sliding member 42 includes a ball bracket 421 and an adapter seat 422; the ball bracket 421 is movably arranged on the slide rail 41 in the width direction, the adapter seat 422 is connected to the ball bracket 421, the supporting member 51 is connected to the adapter seat 422, and the hanging member 52 is connected to the cabinet door 2.

[0093] It can be understood that the slide rail 41 can be a C-shaped rail, and a rolling fit can be achieved between the ball bracket 421 and the slide rail 41 by using balls, so that the sliding member 42 can move smoothly relative to the slide rail 41 and there will be no abnormal noise during the movement.

[0094] At the same time, the adapter seat 422 and the ball bracket 421 can be connected by welding, and the adapter seat 422 and the supporting member 51 can be set as an integral structure, so that in practical applications, the installation of the supporting member 51 is not required, and it is convenient to support the cabinet door 2 through the supporting member 51.

[0095] Furthermore, along the extending direction of the slide rail 41, the extending length of the ball bracket 421 can be set to be greater than the extending direction of the adapter seat 422. This design can increase the contact area between the ball bracket 421 and the slide rail 41 and reduce the contact friction between the ball bracket 421 and the slide rail 41, thereby ensuring the stability and reliability of the movement of the sliding member 42 relative to the slide rail 41.

[0096] In some embodiments, Figure 9 As shown, the door assembly also includes: a sliding door mechanism 6, which is arranged on the cabinet body 3 or the cabinet door 1, and is transmission-connected to the cabinet door 2, and is used to drive the cabinet door 2 to move relative to the cabinet door 1 along the width direction during the opening and closing process of the cabinet door 1; the refrigeration equipment is configured to be arranged in the accommodating space between the first cabinet body 7 and the second cabinet body 8; during the opening or closing process of the cabinet door 1, the sliding door mechanism 6 is used to change the position of the cabinet door 2 on the cabinet door 1 so that the cabinet door 2 avoids the first cabinet body 7 or the second cabinet body 8.

[0097] It is understandable that an opening is provided on the outside of the accommodation space between the first cabinet 7 and the second cabinet 8, and this design allows the cabinet 3 of the refrigeration equipment to be integrally embedded in the accommodation space. In the process of the cabinet door 1 passing through the opening to control the opening or closing of the accommodation space, the sliding door mechanism 6 is configured to drive the cabinet door 2 to move in the width direction away from or close to the hinge 9. This design can ensure that the cabinet door 2 avoids the side walls of the first cabinet 7 and the second cabinet 8, and avoids the side edges of the cabinet door 2 from interfering with the side walls of the first cabinet 7 and the second cabinet 8, thereby meeting the requirement that the cabinet door 1 can be opened and closed smoothly.

[0098] During the process of opening the cabinet door 1, the sliding door mechanism 6 drives the cabinet door 2 to move a preset distance along the width direction toward the side away from the hinge 9, so that the cabinet door 2 can smoothly avoid the side wall of the second cabinet body 8, so that the cabinet door 1 can be fully opened, making it convenient for users to store and retrieve items.

[0099] Similarly, in the process of closing the box door 1, the sliding door mechanism 6 drives the cabinet door 2 to move a preset distance along the width direction toward the side close to the hinge 9. When the cabinet door 1 is completely closed, the cabinet door 2 will return to its initial position. In this way, the cabinet door 2 can smoothly avoid the side wall of the first cabinet body 7, so that the cabinet door 1 can be completely closed to maintain the overall aesthetics and sealing.

[0100] In this embodiment, the cabinet door 2 is movably arranged on the outside of the cabinet door 1 along the width direction of the cabinet door 1, and the sliding door mechanism 6 is used to drive the cabinet door 2 to move relative to the cabinet door 1 during the process of opening or closing the cabinet door 1, so that the cabinet door 1 can avoid the first cabinet body 7 and the second cabinet body 8 on the side during the process of opening and closing, avoiding the interference between the cabinet door 2 and the outside when the cabinet door 1 rotates, and can meet the user's use needs in different scenarios. This design not only improves the convenience of use, but also avoids possible damage to the door body assembly during use. At the same time, this design also allows the refrigeration equipment to be better integrated into the home environment, achieving the effect of overall beauty and sealing.

[0101] In some embodiments, the sliding door mechanism 6 is connected to the sliding member 42 to drive the sliding member 42 to move along the slide rail 41 in the width direction of the cabinet door 1 .

[0102] It is understandable that during the opening and closing process of the cabinet door 1, the sliding door mechanism 6 drives the sliding member 42 to move relative to the slide rail 41 in the width direction. Since the sliding member 42 is connected to the cabinet door 2 through the hanging structure 5, the sliding door mechanism 6 is utilized to drive the cabinet door 2 to move relative to the cabinet door 1, ensuring that the cabinet door 2 does not touch the side cabinet body. This design realizes the integration of the sliding door mechanism 6 and the sliding module 4.

[0103] Among them, since there are multiple sliding modules 4, at least one of the multiple sliding modules 4 close to the hinge 9 can be integrally designed with the sliding door mechanism 6.

[0104] In some embodiments, as Figure 8 and Figure 9 shown, the cabinet door 1 is rotatably connected to the cabinet body 3 of the refrigeration device through the hinge 9, and the cabinet door 2 can move between a first position and a second position relative to the cabinet door 1 in the width direction; when the cabinet door 2 is in the first position, the cabinet door 1 closes the storage compartment, and the side of the cabinet door 2 facing the hinge 9 approaches the hinge 9; when the cabinet door 2 is in the second position, the cabinet door 1 opens the storage compartment, and the side of the cabinet door 2 facing the hinge 9 moves away from the hinge 9. At this time, the sides of the cabinet door 2 and the cabinet door 1 are misaligned to avoid the side walls of the first cabinet body 7 or the second cabinet body 8.

[0105] It is understandable that the storage compartment is used to store items to be refrigerated or frozen. When the cabinet door 1 closes the storage compartment, the cabinet door 1 is in the closed state, and the side of the cabinet door 2 is at a first distance (close to zero) relative to the hinge 9 of the refrigeration device. For example, the sides of the cabinet door 2 and the cabinet door 1 are flush. At this time, the cabinet door 2 can completely block the cabinet door 1, ensuring that the cabinet door 2 of the refrigeration device exposed in the accommodation space is consistent with the surrounding first cabinet body 7 and second cabinet body 8 in appearance.

[0106] When the cabinet door 1 opens the storage compartment, the cabinet door 1 is in the open state, and the side of the cabinet door 2 is at a second distance (the second distance is greater than the first distance) relative to the hinge 9 of the refrigeration device. For example, the sides of the cabinet door 2 and the cabinet door 1 are misaligned, and a gap is formed that can accommodate the side of the first cabinet body 7 or the second cabinet body 8, so as to avoid collision or interference between the cabinet door 2 and the first cabinet body 7 or the second cabinet body 8 due to the opening of the cabinet door 1.

[0107] In some embodiments, as Figure 9 shown, the sliding door mechanism 6 includes: a trigger member and a linear drive member. The trigger member is used to obtain the opening and closing signal of the cabinet door 1; the linear drive member is arranged between the cabinet door 1 and the cabinet door 2 and is connected to the trigger member; among them, the linear drive member is used to drive the cabinet door 2 to move along the width direction of the cabinet door 1 according to the opening and closing signal fed back by the trigger member.

[0108] It is understandable that, for the convenience of controlling the working state of the linear driving member according to the opening and closing signals fed back by the triggering member, the triggering member and the control module can be electrically connected, and the control module and the linear driving member can be electrically connected.

[0109] The triggering member can be a photoelectric switch, which judges the opening and closing state of the box door 1 by detecting the distance change of the box door 1 relative to the box body 3. The triggering member can also be an angle sensor, which judges the opening and closing state of the box door 1 by detecting the angle change of the box door 1 relative to the box body 3;

[0110] The linear driving member can be a telescopic rod such as a cylinder or an electric push rod. The linear driving member extends in the width direction. The first end of the linear driving member is connected to the box door 1, and the second end of the linear driving member is connected to the cabinet door 2 to drive the cabinet door 2 to move relative to the box door 1 in the width direction.

[0111] Among them, in the case where the door body assembly includes the above-mentioned sliding module 4 and the hanging structure 5, the linear driving member is arranged on the box door 1. The first end of the linear driving member is connected to the box door 1, and the second end of the linear driving member is connected to the sliding member 42 of the sliding module 4.

[0112] Taking the triggering member as an angle sensor as an example below, the control of the cabinet door 2 by the linear driving member during the opening and closing process of the box door 1 will be specifically described as follows.

[0113] In practical applications, the angle sensor is installed on the hinge shaft corresponding to the hinge 9 to monitor the rotation state of the box door 1 relative to the hinge shaft. When the box door 1 is opened, the angle sensor feeds back an opening signal to the linear driving member, and the linear driving member drives the cabinet door 2 to move away from the hinge 9 in the width direction of the box door 1; when the box door 1 is closed, the angle sensor feeds back a closing signal to the linear driving member, and the linear driving member drives the cabinet door 2 to move closer to the hinge 9 in the width direction of the box door 1.

[0114] Furthermore, as the opening or closing amplitude of the box door 1 is different, the angle sensor can also obtain the rotation angle of the box door 1. The linear driving member can determine the preset value of the movement according to the rotation angle. During the opening process of the box door 1, according to the rotation angle when the box door 1 is opened, the stroke of the telescopic end of the linear driving member is determined, and then the linear driving member drives the cabinet door 2 to move a preset distance away from the hinge 9 to avoid interference between the cabinet door 2 and the external cabinet body; correspondingly, during the closing process of the box door 1, according to the rotation angle when the box door 1 is closed, the stroke of the telescopic end of the linear driving member is determined, and then the linear driving member drives the cabinet door 2 to move a preset distance closer to the hinge 9 to avoid interference between the cabinet door 2 and the external cabinet body, and finally realizes the reset of the cabinet door 2.

[0115] In some embodiments, to ensure the stability and reliability of the movement of the cabinet door 2 relative to the box door 1, multiple sets of sliding modules 4 and hanging structures 5 are respectively provided and arranged in a one-to-one correspondence. At least one set of sliding modules 4 is provided between the upper ends of the box door 1 and the cabinet door 2, and at least one set of sliding modules 4 is provided between the lower ends of the box door 1 and the cabinet door 2.

[0116] Specifically, four sets of sliding modules 4 are provided. Two of the sliding modules 4 are arranged along the width direction of the box door 1 and are provided between the upper ends of the box door 1 and the cabinet door 2. The other two sets of sliding modules 4 are arranged along the width direction of the box door 1 and are provided between the lower ends of the box door 1 and the cabinet door 2.

[0117] In some embodiments, as Figure 7 shown, the box door 1 is provided with a groove 101, and the sliding module 4 is arranged in the groove 101; the door body assembly further includes a decorative member, and the decorative member cover is used to cover the notch end of the groove 101.

[0118] It can be understood that when the cabinet door 2 is installed on the outer side of the box door 1, the sliding module 4 on the box door 1 is connected to the cabinet door 2 through the hanging structure 5. At this time, there is no decorative member at the notch end of the groove 101. The slide rail 41 of the sliding module 4 is connected to the groove wall of the groove 101.

[0119] In some application scenarios, if the cabinet door 2 is no longer installed on the outer side of the box door 1, at this time the sliding module 4 is no longer used. By covering the notch end of the groove 101 with the decorative member, a hidden design of the sliding module 4 can be realized to ensure the aesthetic appearance of the box door 1.

[0120] In a second aspect, as Figure 7 、 Figure 8 and Figure 9 shown, an embodiment of the present invention further provides a refrigeration device, including: a box body 3 and the door body assembly as described in any one of the above. The box body 3 has a storage compartment, and the box door 1 is rotatably arranged on the box body 3 to open or close the storage compartment.

[0121] It can be understood that the box body 3 can be provided with multiple storage compartments, and the multiple storage compartments are arranged in sequence from top to bottom along the height direction of the box body 3. The box body 3 is configured with a set of door body assemblies for controlling the opening and closing states for each storage compartment. Among them, a hinge 9 is provided on one side of the box body 3 corresponding to each storage compartment, and the box body 3 can be rotatably connected to the box door 1 of the door body assembly corresponding to the storage compartment through the hinge 9.

[0122] For each set of door body components, since the cabinet door 2 can move left and right relative to the box door 1 in the width direction, when the refrigeration equipment is fully embedded, during the process of opening the box door 1, the cabinet door 2 can be controlled to move away from the hinge 9 relative to the box door 1 to avoid the cabinet body around the refrigeration equipment; during the process of closing the box door 1, the cabinet door 2 can be controlled to move closer to the hinge 9 relative to the box door 1 until the cabinet door 2 returns to its original position, ensuring that the side edges of the box door 1 and the cabinet door 2 are flush.

[0123] Since the refrigeration equipment includes a door body component, and the specific structure of the door body component refers to the above-mentioned embodiment, the refrigeration equipment shown in this embodiment includes all the technical solutions of the above-mentioned embodiment. Therefore, it has at least all the beneficial effects achieved by all the technical solutions of the above-mentioned embodiment, which will not be elaborated here one by one.

[0124] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should all be covered by the scope of the claims of the present invention.
