Description

Technical Field

[0001] The invention relates to a method for using kitchen appliances, in particular to a drying method for a food processor. Background Art

[0002] Existing patent CN202222794810.1 discloses an air-drying food processor, which discloses that after the food cup is cleaned, it is air-dried by an air-drying component installed at the mounting port of the food cup. When the fan in the cover seat is working, the airflow can be introduced into the food cup to air-dry the food cup, thereby achieving rapid drying of the food processor. Since the food processor uses a fan to air-dry the food cup, a separate fan needs to be provided on the cover seat of the food processor, which not only makes the structure of the whole machine complex, but also has a high manufacturing cost. At the same time, the inventor found that the air-drying effect at the bottom of the food cup is not thorough, and there are still residual water droplets that are not completely dried.

[0003] At the same time, the existing patent CN202120443290.2 also discloses a food processing machine, the processing chamber of which is provided with a fan blade, the control component synchronously controls the operation of the drying component and the fan blade, and the drying component heats the air in the processing chamber to evaporate the residual water into water vapor, and at the same time, the fan blade rotates so that the air in the processing chamber can form forced convection, and the hot air will circulate along the air flow channel with the outside atmosphere to achieve the drying of the processing chamber. In this patent, the fan blade is actually a crushing blade arranged at the bottom of the processing chamber, and the crushing blade is controlled by a motor to rotate at high speed. During the idling process of the crushing blade, the flow of air in the processing chamber can indeed be achieved. However, the inventor found through research that only the air flowability on the side of the bottom of the processing chamber close to the crushing blade is strong, while the air flowability on the side of the processing chamber close to the cup cover is poor. Therefore, in fact, the effect of the hot air in the processing chamber circulating with the outside atmosphere is not good, resulting in an unsatisfactory drying effect. After the drying is completed, there will still be residual water droplets after steam condensation in the processing chamber.

[0004] In addition, there is another existing patent CN202221840253.6, which discloses that a blade part and a blade are provided on the knife shaft in the cooking cup, the blade is used to crush the material, and the blade part is used to guide the hot air to flow in the cooking cup when the knife shaft rotates, so as to dry the cooking cup, wherein the knife shaft is driven to rotate by a driving member (motor). When drying the cooking cup, the driving member drives the knife shaft to rotate, and the rotation of the knife shaft can drive the blades on the knife shaft to rotate, and the rotation of the blade part can guide the hot air flow in the cooking cup to achieve hot air drying, so that the cooking cup can be used directly in a dry state. Compared with the previous patent scheme, this patent scheme can further improve the fluidity of the air in the cooking cup. However, the inventor has found that during the drying process, the air fluidity on the side close to the knife shaft is better, and the corresponding part of the cooking cup has a good drying effect, while the air fluidity on the side of the cup cover in the cooking cup away from the knife shaft is relatively poor, and the corresponding cooking cup and cup cover have a poor drying effect. Moreover, although the blades are arranged on the blade shaft, the drying effect of the cooking cup can be improved, but the blade part and the blade are installed on the same blade shaft and are relatively non-detachable. Therefore, during the pulping process, the blade part and the blade will rotate synchronously at high speed. The presence of the blades will seriously affect the effect of the blade on crushing materials. In the pulping process, the blade part may even cause serious splashing of the pulp, posing a safety risk of scalding consumers. Summary of the invention

[0005] The object to be achieved by the present invention is to provide a drying method for a food processing machine, which does not require the provision of additional power and can improve the fluidity of the air in the entire pulping chamber, so that the drying effect of the pulping chamber is more significant.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a drying method for a food processing machine, the food processing machine includes a pulping chamber and a stirring device arranged at the bottom of the pulping chamber, characterized in that: an unpowered paddle is arranged in the pulping chamber, and the unpowered paddle is located above the stirring device. When the residual water in the pulping chamber is dried, the stirring device idles, so that the air flowing in the pulping chamber drives the unpowered paddle to rotate, so as to air-dry the pulping chamber.

[0007] Furthermore, the food processor also includes a heating device, and when the unpowered paddle rotates to air-dry the pulping chamber, the heating device heats and dries the pulping chamber.

[0008] Furthermore, the pulping chamber is provided with a communication port communicating with the outside, and a breathable cover is installed at the communication port. When the unpowered paddle is rotating to air-dry the pulping chamber, the breathable cover is in a state of opening the communication port.

[0009] Furthermore, the pulping chamber is provided with an air hole connected to the outside, and the unpowered paddle is an axial flow fan blade, and the axial flow fan blade is located below the air hole, and the axial flow fan blade draws air toward the air hole during rotation.

[0010] Furthermore, the stirring device comprises a crushing blade, and the crushing blade has a pumping part for pumping air upwards when rotating.

[0011] Furthermore, the pumping part includes a blade disposed on the crushing blade and bent upward;

[0012] Alternatively, the pumping portion includes a twisted blade disposed on a crushing blade;

[0013] Alternatively, the pumping portion comprises a blade disposed on the crushing blade with the cutting edge facing upward.

[0014] Furthermore, the axial distance between the unpowered paddle and the stirring device does not exceed 100 mm.

[0015] Furthermore, a drain port is provided at the bottom of the pulping chamber, and a drain valve for opening and closing the drain port is installed at the drain port. When the unpowered paddle is rotating to air-dry the pulping chamber, the drain port is in an open state.

[0016] Furthermore, a material discharge assembly is provided in the pulping chamber, and the material discharge assembly is located above the stirring device, the material discharge assembly includes a barrel having an upper feed port, a lower discharge port, and a switch component arranged at the discharge port, the switch component is used to open and close the discharge port, the unpowered paddle is located below the discharge port, the barrel is connected to the outside through the feed port, and during the process of drying the pulping chamber, the switch component opens the discharge port, and the air flowing in the pulping chamber drives the unpowered paddle to rotate, so as to air-dry the pulping chamber and the barrel.

[0017] Furthermore, the switch member is connected to the barrel through a rotating shaft structure, and the rotating shaft structure is arranged on the barrel, and the unpowered paddle is arranged below the switch member. During the drying process of the pulping chamber, the air flowing in the pulping chamber drives the unpowered paddle to drive the switch member to rotate around the rotating shaft structure, and the switch member intermittently opens the discharge port;

[0018] Alternatively, a mounting portion fixed to the barrel is provided at the discharge port, the unpowered paddle is mounted on the mounting portion via a rotating shaft, and the unpowered paddle rotates around the rotating shaft, wherein during the drying process of the pulping chamber, the switch element is always in an open discharge port state;

[0019] Alternatively, the unpowered paddle includes an axial flow fan blade that draws air downward, and an air outlet connected to the inner cavity of the barrel is provided on the peripheral wall of the barrel. The air outlet is located above the discharge port and close to the feed port, and the flowing air in the pulping chamber is discharged through the air outlet, the inner cavity of the barrel and the feed port.

[0020] After cleaning, the pulping chamber of the existing food processing machine is generally naturally air-dried, which takes a long time. If it is naturally air-dried, the residual water remaining in the pulping chamber will breed bacteria, mold, and produce odor. Even if the user cleans the pulping chamber before each use, it cannot be guaranteed that the mold can be cleaned up. In order to speed up the air-drying speed, some users will open the cover to air-dry, but dust will inevitably fall when the cover is opened for air-drying. Based on this, the industry has used the high-speed rotation of the crushing blade to force convection of the air in the pulping chamber, thereby accelerating the air exchange with the outside world and making the pulping chamber dry faster. For example, patents CN202120443290.2 and CN202221840253.6. However, the inventors found through research that the above scheme is not thorough in drying the pulping chamber. Because, during the high-speed rotation of the crushing blade, the air in the pulping chamber will indeed flow at a high speed. However, the air in the pulping chamber has different height layers relative to the crushing blade, and the air flow rates of different height layers are not the same. The air near the crushing blade rotates faster and has better flow rates, but the air far away from the crushing blade rotates slower and has relatively poor flow rates. However, the air vents on the pulping chamber are generally located at the top of the pulping chamber and are relatively small. Therefore, the air flow rate of the air in the pulping chamber is not uniform. Even if the air flow rate at the bottom of the pulping chamber is faster, the air flow rate near the cup lid is not fast, and it cannot achieve rapid exchange with the outside world through the air vents. This makes the air drying effect of the entire pulping chamber fail to reach an ideal level.

[0021] The present invention innovatively proposes to set an unpowered paddle in the pulping chamber. After the pulping chamber is cleaned, when the residual water in the pulping chamber is dried, the air flow caused by the idling of the stirring device is used to drive the unpowered paddle to rotate, and then the rotational inertia of the unpowered paddle is used to reversely drive the air flow in the upper part of the pulping chamber to rotate, thereby achieving an increase in the air flow speed in the entire pulping chamber, forming convection of the air in the entire pulping chamber. It is precisely because of the increase in the air flowability in the entire pulping chamber that the corresponding exchange efficiency between the air in the pulping chamber and the outside world is higher, and it is easier to dry and air-dry the pulping chamber. Therefore, compared with the existing automatic drying food processing machine, the food processing machine using the drying method of the present invention has a simpler structure and lower manufacturing cost. It is not necessary to set up a separate power to drive the paddle to rotate. Moreover, the pulping chamber can be air-dried more quickly without the user having to perform additional operations.

[0022] The present invention will be further described below in conjunction with the accompanying drawings:

[0027] Embodiment 1:

[0028] like Figure 1 The figure shows a simple structural schematic diagram of the food processing machine of the present invention. The food processing machine comprises a cup body 1 and a cup cover 2 sealedly mounted on the cup body 1, wherein the cup body 1 and the cup cover 2 enclose a pulping chamber 10, a motor 3 is arranged at the bottom of the cup body 1, a rotating shaft 31 driven by the motor 3 penetrates the bottom of the cup body 1 and extends into the pulping chamber 10, wherein a stirring device 4 is installed at the end of the rotating shaft 31 and is located in the pulping chamber 10, a non-powered paddle 5 is installed on the cup cover 2, and an air hole 20 connected to the pulping chamber 10 is arranged on the cup cover 2, the non-powered paddle 5 is located above the stirring device 4 and is arranged directly opposite to the stirring device 4, and the non-powered paddle 5 is located below the air hole 20.

[0029] In this embodiment, the non-powered blade 5 can rotate horizontally, and the food processor of this embodiment has an automatic drying mode. After the cup body 1 and the cup cover 2 of the food processor are cleaned, the food processor is powered on and enters the automatic drying mode, the stirring device 4 is in an idling state, and the air in the pulping chamber 10 is driven by the stirring device 4 to rotate and flow, and the rotating air flow drives the non-powered blade 5 to rotate at a high speed. It is precisely because of the high-speed continuous 360° rotation of the non-powered blade 5 that the air flow in the pulping chamber 10 can be exchanged with the outside world through the air vent 20, so that the pulping chamber 10 can be air-dried. Among them, the non-powered blade 5 is an axial flow fan blade that pumps air upward. In the process of drying the pulping chamber 10, the non-powered blade 5 pumps air toward the air vent 20.

[0030] After cleaning, the pulping chamber of the existing food processing machine is generally naturally air-dried, which takes a long time. If it is naturally air-dried, the residual water remaining in the pulping chamber will breed bacteria, mold, and produce odor. Even if the user cleans the pulping chamber before each use, it cannot be guaranteed that the mold can be cleaned up. In order to speed up the air-drying speed, some users will open the cover to air-dry, but dust will inevitably fall when the cover is opened for air-drying. Based on this, the industry has used the high-speed rotation of the crushing blade to force convection of the air in the pulping chamber, thereby accelerating the air exchange with the outside world and making the pulping chamber dry faster. For example, patents CN202120443290.2 and CN202221840253.6. However, the inventors found through research that the above scheme is not thorough in drying the pulping chamber. Because, during the high-speed rotation of the crushing blade, the air in the pulping chamber will indeed flow at a high speed. However, the air in the pulping chamber has different height layers relative to the crushing blade, and the air flow rates of different height layers are not the same. The air near the crushing blade rotates faster and has better flow rates, but the air far away from the crushing blade rotates slower and has relatively poor flow rates. However, the air vents on the pulping chamber are generally located at the top of the pulping chamber and are relatively small. Therefore, the air flow rate of the air in the pulping chamber is not uniform. Even if the air flow rate at the bottom of the pulping chamber is faster, the air flow rate near the cup lid is not fast, and it cannot achieve rapid exchange with the outside world through the air vents. This makes the air drying effect of the entire pulping chamber fail to reach an ideal level.

[0031] The present embodiment innovatively proposes to set an unpowered paddle in the pulping chamber. After the pulping chamber is cleaned, when the residual water in the pulping chamber is dried, the air flow caused by the idling of the stirring device is used to drive the unpowered paddle to rotate, and then the rotational inertia of the unpowered paddle is used to reversely drive the air flow in the upper part of the pulping chamber to accelerate the rotation, thereby achieving an increase in the air flow speed in the entire pulping chamber and forming a strong convection in the entire pulping chamber. It is precisely because of the increase in the air flowability in the entire pulping chamber that the corresponding exchange efficiency between the air in the pulping chamber and the outside world is higher, and it is easier to dry and air-dry the pulping chamber. Therefore, compared with the existing automatic drying food processing machine, the automatic drying method of the food processing machine of the present embodiment is simpler and more efficient. Moreover, the structure of the food processing machine of the present embodiment is also simpler, and the manufacturing cost is lower. There is no need to set a separate power to drive the paddle to rotate. Moreover, the pulping chamber can be air-dried more quickly without the user having to perform additional operations.

[0032] In addition, during the pulping process, when the stirring device drives the liquid flow to rotate, the unpowered paddles can also be driven to rotate by the liquid flow, thereby disrupting the rotation of the liquid flow, reducing the risk of slurry splashing, and preventing users from being scalded. At the same time, the disrupted liquid flow is also conducive to increasing the probability of collision between the material and the stirring device, which can significantly improve the crushing fineness.

[0033] It should be noted that the food processor of this embodiment also includes a heating device. During the process of rotating and air-drying the pulping chamber using the unpowered paddles, the heating device can simultaneously heat the pulping chamber to achieve drying, evaporation and sterilization of the residual water in the pulping chamber. In this embodiment, the heating and drying of the pulping chamber can continue throughout the entire automatic drying process, or it can be continuous or intermittent heating and drying within a certain period of time during the drying process. It should be pointed out that since the power source of the unpowered paddles is the air flow driven by the idling of the stirring device, if the air cannot flow continuously, the corresponding unpowered paddles will no longer be powered. Therefore, in order to ensure the continuous rotation of the unpowered paddles, the stirring device needs to be in a rotating state at all times.

[0034] It should also be noted that the stirring device in this embodiment includes a crushing blade, which can drive the unpowered blade to rotate during the high-speed rotation of the crushing blade. In order to achieve faster rotation of the unpowered blade, a pumping part can be provided on the crushing blade in this embodiment, and the pumping part can pump the liquid flow or air flow upward, so that the height of the upward disturbance of the liquid flow or air flow is higher, which is more conducive to driving the unpowered blade to rotate. Among them, the pumping part can be a blade bent upward on the crushing blade, or a blade twisted on the crushing blade, or a blade with the blade facing upward. Of course, the axial spacing between the unpowered blade and the stirring device cannot be too large. The inventor found through research that the axial height of the two is generally not more than 100mm. The existing stirring devices can realize that the crushing blade drives the unpowered blade to rotate through the airflow, and if the axial height of the two exceeds 100mm, it will be difficult for the crushing blade to drive the unpowered blade to rotate through the airflow, or, even if the unpowered blade can rotate, the rotation speed is very slow, and the air drying effect of the pulping chamber cannot be achieved. For this embodiment, the axial spacing from the unpowered paddle to the stirring device is preferably selected to be 10 mm to 80 mm.

[0035] Of course, for the cup cover of the present embodiment, a connecting port may also be provided on the cup cover, and a breathable cover may be installed at the connecting port, and the breathable holes are provided on the breathable cover. If the breathable holes are small, the air in the pulping chamber cannot be quickly exchanged with the outside world. In the process of automatic drying of the food processor, the breathable cover may be opened to realize direct air exchange between the pulping chamber and the outside world through the connecting port.

[0036] It should be noted that the above-mentioned structural transformation and parameter selection of this embodiment can also be applied to other embodiments of the present invention.

[0037] Embodiment 2:

[0038] like Figure 2 , Figure 3 , Figure 4 As shown, it is a schematic diagram of the structure of the second embodiment of the food processing machine of the present invention. The difference between this embodiment and the first embodiment is that: a feeding assembly 6 is installed on the cup cover 2, and the lower part of the feeding assembly 6 extends into the pulping chamber 10, the feeding assembly 6 includes a barrel 61 with an upper feed port 611 and a lower discharge port 612, and a switch 62 arranged at the discharge port 612, the switch 62 is used to open and close the discharge port 612, the unpowered paddle 5 is located below the discharge port 612, and the barrel 61 is connected to the outside through the feed port 611. Among them, a rotating shaft structure 63 is arranged between the edge of the switch 62 and the peripheral wall of the barrel 61, and the switch 62 is connected to the barrel 61 through the rotating shaft structure 63, and the unpowered paddle 5 is fixed to the lower end of the switch 62.

[0039] In this embodiment, the lower open end of the barrel 61 forms a discharge port 612, and the switch member 62 is a tray for closing the lower open end of the barrel 61, and the materials in the barrel 61 are all supported by the tray. Among them, the rotating shaft structure 63 includes a pin 631, and a mounting hole 610 is provided at the bottom of the peripheral wall of the barrel 61. A corresponding shaft hole 620 is provided on the switch member 62, and the pin 631 passes through the shaft hole 620 and is fixed on the mounting hole 610, so that the switch member 62 rotates around the pin 631. The unpowered paddle 5 is detachably fixed to the bottom wall of the switch member 62. In order to prevent the switch 62 from warping downward at the end away from the pin 631 and failing to close the discharge port 612, a first magnet 625 is installed on the side of the switch 62 away from the pin 631, and a second magnet 615 that attracts the first magnet 625 is provided at a corresponding position of the peripheral wall of the barrel 61. The switch 62 and the barrel 61 can be initially limited by the mutual attraction of the first magnet 625 and the first magnet 615 to prevent the switch 62 from rotating unnecessarily during the loading process. At the same time, a breathable cover 64 is hingedly installed at the feed port 611, and the breathable cover 64 is used to cover the feed port 611 to prevent dust from entering the barrel 61.

[0040] For this embodiment, during the pulping process, when the crushing blade rotates at high speed, the rotating liquid flow can drive the unpowered paddle to rotate, and the unpowered paddle can then drive the switch part to rotate around the pin shaft, so that the switch part opens the discharge port, and the food processor automatically discharges the food during the pulping process. At the same time, the food processor of this embodiment also has an automatic drying program operation. During the automatic drying process, the crushing blade idles, and the air flowing in the pulping chamber drives the unpowered paddle to drive the switch part to rotate 360° around the pin shaft, and the switch part intermittently opens the discharge port, so that the air in the pulping chamber is exchanged with the outside through the barrel, such as Figure 4 As shown, during the automatic drying process of the food processor, the air permeable cover is in an open feed inlet state. This embodiment also has the same beneficial effects as the first embodiment, which will not be repeated here. It should be noted that during the automatic drying process of the pulping chamber, the inner wall of the barrel is dried synchronously.

[0041] For the barrel of this embodiment, since the bottom of the barrel is open, it is a structure without a bottom wall, and does not have the function of supporting materials, but only has the function of accommodating materials, and all the materials are supported by the switch member (tray). It is also because the barrel does not have the function of supporting materials, so when the switch member opens the discharge port relative to the barrel, the barrel has a larger discharge opening, and the materials in the barrel can fall into the cup body more quickly. At the same time, when the switch member rotates to open the discharge port, the inner circumferential wall of the barrel will form a blocking effect on the materials on the switch member, so that the materials on the switch member will be scraped off into the cup body by the inner circumferential wall of the barrel, so that there will be no material residue on the switch member. Compared with the existing food processing machine with automatic discharge structure, the structure of the discharge assembly of this embodiment can realize more thorough material discharge. In addition, since the switch member rotates around the pin shaft, the switch member can rotate clockwise with the liquid flow to open the discharge port, and can also rotate counterclockwise with the liquid flow to open the discharge port. Therefore, the versatility of the discharge assembly of this embodiment is better, and it can be applied to food processing machines with different steering motors. For the blanking assembly of this embodiment, the switch member can rotate 360° along with the unpowered paddle.

[0042] It should be noted that the shaft structure is not limited to the pin shaft disclosed in this embodiment, and may also be other structures, for example: the shaft structure includes a shaft fixed to the switch member and a shaft groove provided on the peripheral wall of the barrel, and the shaft is clamped in the shaft groove, and the shaft can be located in the shaft groove and rotate. For this structure, the shaft and the switch member are integrally formed, and the shaft is removable relative to the shaft groove to facilitate the user to disassemble and clean it by themselves. In addition, the switch member and the unpowered paddle can also be disassembled relative to the barrel to facilitate the user to clean the dead corners by themselves. For this embodiment, the shaft structure is not limited to being installed on the peripheral wall of the barrel, and the shaft structure can also be directly provided at the discharge port of the barrel. For example, the barrel has a partial bottom wall, and the shaft structure is provided between the bottom wall of the barrel and the switch member; or a mounting portion connected to the peripheral wall of the barrel is provided at the center of the discharge port of the barrel, and the shaft structure is directly provided on the mounting portion.

[0043] At the same time, the unloading assembly of this embodiment is not limited to the scheme disclosed in this embodiment. For example, a mounting portion fixed to the barrel is provided at the discharge port, and the unpowered paddle is installed on the mounting portion through a rotating shaft. The unpowered paddle can rotate around the rotating shaft, but there is no connection between the switch and the unpowered paddle. The switch can independently open and close the discharge port. In the process of automatic drying of the pulping chamber, the discharge port can be opened by the switch first, and the discharge port is always in an open state. Then, the airflow is used to drive the unpowered paddle to rotate, so as to dry the pulping chamber and the barrel. Similarly, the unpowered paddle can also be connected to the peripheral wall of the barrel through a rotating shaft structure to realize the offset setting of the unpowered paddle relative to the barrel.

[0044] Of course, for this embodiment, an air outlet connected to the inner cavity of the barrel can be provided on the peripheral wall of the barrel, and the air outlet is located above the discharge port and close to the feed port, and the unpowered paddle can be arranged as an axial flow fan blade that pumps air downward. During the automatic drying of the pulping chamber, the axial flow fan blade rotates and pumps air downward, and the outside air enters the pulping chamber through the feed port, the center of the inner cavity of the barrel and the discharge port. With the movement of the air flow, the original air in the pulping chamber will be discharged to the outside through the air outlet, the edge of the inner cavity of the barrel and the feed port, thereby realizing the circulation of air inside and outside the pulping chamber, which is more conducive to the air drying of the pulping chamber. Moreover, for this embodiment, the air outlet provided on the barrel can also be used as a flushing hole. During the scheduled pulping process, when the unloading component is unloading, the rotating liquid flow can enter the barrel through the flushing hole (air outlet), thereby flushing the material adhering to the inner wall of the barrel, and achieving more thorough unloading. In order to facilitate the rotating liquid flow to enter the barrel more easily through the flushing hole, at this time, the barrel can be offset relative to the pulping chamber, so that the liquid flow can more easily rush into the barrel from the flushing hole during the rotation process. Generally, the flushing hole is preferably closer to the side of the barrel near the inner wall of the pulping chamber. Of course, in order to increase the amount of liquid flow rushing into the barrel, a baffle rib can also be provided near the flushing hole. After the rotating liquid flow is blocked by the baffle rib, it will rebound into the flushing hole. Among them, along the rotation direction of the liquid flow, the baffle rib is required to be located in front of the flushing hole, otherwise the baffle rib will not achieve the purpose of allowing the liquid flow to rebound into the flushing hole.

[0045] The food processor of the present invention is not limited to the structure disclosed in this embodiment. The food processor of the present invention can be a traditional motor-mounted soymilk machine, a motor-mounted soymilk machine with a motor and a cup body installed in one body, a wall-breaking machine, or a food processor that does not need to be washed by hands. The unpowered paddles in the present invention are not limited to being installed on the cup cover, but can also be directly and detachably installed on the cup body or the machine head. When the unpowered paddles are applied to a food processor that does not need to be washed by hands, since a drain port is provided at the bottom of the pulping chamber, and a drain valve for opening and closing the drain port is installed at the drain port, the drain port can be kept in an open state during the process of the unpowered paddles rotating to air-dry the pulping chamber, which is also conducive to the circulation of air inside and outside the pulping chamber, thereby achieving better drying of the pulping chamber.

[0046] Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
