Description

Technical Field

[0001] The invention relates to a control technology of kitchen appliances, in particular to a control method of a food processor. Background Art

[0002] When preparing soy milk drinks, the existing soy milk machine that can automatically discharge slurry generally adds materials and water according to the ratio requirements. However, in actual use, for simplicity and convenience, consumers will add materials and water to the soy milk machine at will, which may result in more materials being added and less water being added. After the soy milk machine has finished making slurry, the soy milk is thick and contains more residue. In the process of automatically discharging the slurry, the slurry with good fluidity will be discharged quickly, while the slurry residue with poor fluidity cannot be completely discharged and will still remain in the crushing cup of the soy milk machine. Therefore, it is necessary to add water to the soy milk machine many times to flush out the slurry residue, which not only consumes a lot of water, but also causes the slurry residue to be not discharged cleanly.

[0003] At the same time, the applicant has previously applied for invention applications with application numbers "CN201910481587.5" and "CN201910481588.X", respectively, and the names are "A self-cleaning method for a food processing machine" and "An automatic cleaning method for a food processing machine". The above patent applications disclose that during the cleaning process of the food processing machine, water is first injected and whipped to flush and moisten the inner wall of the crushing chamber, and then the inner wall of the crushing chamber is fumigated with steam to soften the residue. Then, during the cleaning stage, the crushing blade drives the cleaning water to clean the crushing chamber and discharge it to the outside. In the above scheme, since an infiltration stage is provided before steaming and fumigation, under the action of high temperature, steam can soften the residue well. However, water still needs to be added multiple times during the cleaning process, and the whipping of the crushing blade is used to flush the inner wall of the crushing chamber to clean the residue. Therefore, the food processing machine in the above application needs to be cleaned with water multiple times, and the amount of cleaning water used is also relatively large. Summary of the invention

[0004] The purpose of the present invention is to provide a control method for a food processing machine that does not require or uses less cleaning water and can discharge impurities (stains, residues or pulp residue) in a pulping chamber through steam. This method can realize automatic sterilization and disinfection of the food processing machine, automatic pulp and residue discharge, automatic cleaning, no need for hand washing, and even automatic heating of the pulp.

[0005] In order to achieve the above object, the present invention adopts the following technical scheme: a control method of a food processing machine, the food processing machine includes a pulping chamber, a drainage component for controlling the opening and closing of the pulping chamber, and a steam generating device for introducing steam into the pulping chamber, characterized in that: the control method includes:

[0006] When the liquid draining assembly is in the open state, the steam generating device introduces steam into the pulping chamber, and the steam is discharged from the pulping chamber through the liquid draining assembly.

[0007] Furthermore, the control method is applied to the slurry discharge process, and the introduced steam drives the slurry in the pulping chamber to be discharged.

[0008] Furthermore, the slurry discharge process includes a juice discharge stage and a slag discharge stage, wherein the control method is applied to the juice discharge stage.

[0009] Furthermore, the slurry discharge process includes a juice discharge stage and a slag discharge stage, wherein the control method is applied to the slag discharge stage.

[0010] Furthermore, after the juice discharge stage is completed and before the slag discharge stage begins, a step of injecting water into the pulping chamber to flush out the slag is also provided;

[0011] Alternatively, during the slag discharge process, a step of injecting water into the pulping chamber to flush out the slag is also provided;

[0012] Alternatively, the food processor further comprises a pulp receiving cup, into which the pulp juice discharged in the juice discharge stage and the pulp residue discharged in the residue discharge stage are both discharged;

[0013] Alternatively, the food processor further comprises a pulp receiving cup and a waste water box, wherein the pulp juice discharged in the juice discharge stage is discharged into the pulp receiving cup, and the pulp residue discharged in the residue discharge stage is discharged into the waste water box.

[0014] Furthermore, after the juice discharge stage is completed and before the slag discharge stage begins, a pressurization stage is provided: the liquid discharge assembly is closed, and the steam generating device introduces steam into the pulping chamber for pressurization.

[0015] Furthermore, during the pressurization stage, steam is continuously or intermittently introduced into the pulping chamber.

[0016] Furthermore, the pulp is raw pulp that has not been boiled, and during the drainage process, the steam generating device introduces steam into the pulping chamber to heat the raw pulp, and during the slag discharge process, the foam formed in the pulping chamber wraps the pulp slag and is discharged by the drainage component.

[0017] Furthermore, during the juice drainage process, steam is continuously or intermittently introduced into the pulping chamber.

[0018] Furthermore, the pulping chamber is a closed structure, and the drainage assembly is the only outlet for steam discharge;

[0019] Alternatively, when the drainage assembly is in the open state, steam is continuously or intermittently introduced into the pulping chamber.

[0020] Furthermore, the food processor also includes a slurry receiving cup, and the slurry in the slurry making chamber is discharged into the slurry receiving cup through a drainage component, wherein the control method is applied to slurry heating, and the introduced steam is discharged by the drainage component and heats the slurry in the slurry receiving cup.

[0021] Furthermore, the slurry discharged into the slurry receiving cup is raw slurry, wherein the steam is used to boil the raw slurry in the slurry receiving cup.

[0022] Furthermore, the control method is applied to the food processing machine before pulping, and the steam introduced is used to steam sterilize the pulping chamber and the drainage component;

[0023] Alternatively, the control method is applied to a cleaning process after pulping, and the introduced steam drives the residue and / or cleaning water in the pulping chamber to be discharged through the drainage assembly.

[0024] The control method of the food processing machine of the present invention is as follows: when the drain assembly is in the open state, the steam generating device continuously or intermittently introduces steam into the pulping chamber, and the steam is discharged from the pulping chamber through the drain assembly. The control method can be applied to the working process of the food processing machine. Compared with the prior art, the control method of the present invention can use steam to discharge impurities in the pulping chamber, such as stains, residues, oil stains, and even pulp residue, etc. out of the pulping chamber, which not only effectively realizes the functions of automatic sterilization and disinfection of the food processing machine, automatic discharge of pulp, no need for hand washing, and automatic heating of pulp, but also, compared with the existing fully automatic soymilk machine, the cleaning and disinfection effect is better, the pulp is discharged more cleanly, the amount of water used for cleaning is also less, and even no washing water is needed, and compared with the existing food processing machine that can heat the pulp with steam, the scheme of heating the pulp of the present invention is simpler.

[0025] The control method of the present invention can be applied before pulping, and the steam introduced can perform high-temperature sterilization and disinfection on the cavity wall and drainage component of the pulping chamber. On the one hand, because the temperature of the steam is relatively high, after the high-temperature steam fills the pulping chamber, it will heat the cavity wall surface of the pulping chamber, so that the cavity wall surface temperature rises rapidly, forming a pasteurization and disinfection effect. On the other hand, in the process of high-temperature steam entering the pulping chamber, when the steam encounters a cold chamber, it will quickly liquefy and condense into water droplets, and the water droplets will slide down along the cavity wall of the pulping chamber, while absorbing mold, stains, oil stains and dust on the cavity wall, and the subsequent steam introduced can also accelerate the downward push of the previously condensed water droplets, and discharge them through the drainage component (the direction of the steam flow path).

[0026] At the same time, the control method of the present invention can also be applied to the discharge process of slurry. The steam introduced can quickly discharge the slurry and slurry residue, and the discharge of the slurry residue is cleaner and uses less water. This is mainly because: first, when high-temperature steam is introduced into the pulping chamber and encounters the cold cavity wall, it will liquefy and condense into water droplets. The condensed water droplets will flush the cavity wall under the action of gravity and adsorb the residue on the cavity wall. Moreover, when the water droplets gather on the cavity bottom wall, they will further mix with the slurry residue on the cavity bottom wall, thereby forming a slurry with good fluidity again and being discharged through the drainage component. Second, after the food processor prepares the slurry, a layer of slurry foam will form on the surface of the slurry, which will hang on the cavity wall. After the high-temperature steam is introduced into the pulping chamber, the pressure in the pulping chamber will continue to increase. Under the dual effects of high temperature and pressure, the fine slurry foam will break and disappear, and will be mixed with the slurry residue on the cavity bottom wall under the flushing of the condensed water droplets. Moreover, the drainage component is located at the bottom of the pulping chamber and is the main circulation channel for steam discharge. Therefore, the steam will carry the mixed juice and pulp residue and discharge through the drainage component. Third, when the slurry prepared by the food processor is raw slurry, due to the high temperature of the steam entering the pulping chamber, the undischarged raw juice will produce a large amount of foam under the heating effect of the high-temperature steam and wrap the pulp residue on the bottom wall of the chamber, thereby greatly improving the fluidity of the pulp residue and being more conducive to the discharge of the pulp residue. Therefore, even if water is not introduced into the pulping chamber (the pulp residue is mixed with water to improve the fluidity of the pulp residue), after steam is introduced into the pulping chamber for a certain period of time, the pulp residue can be discharged from the pulping chamber through the drainage component under the multiple effects of steam.

[0027] Secondly, the control method of the present invention can also be applied to the cleaning process after pulping. The high-temperature steam passed into the pulping chamber will liquefy and condense into water droplets. The condensed water droplets will flush the cavity wall under the action of gravity, while absorbing the residue on the cavity wall and being discharged through the drainage component. Compared with the existing soymilk machines that can realize automatic cleaning, the pulping chamber can be cleaned by opening the drainage component and continuously passing steam for cleaning. There is no need for cleaning water at all.

[0028] Even if water cleaning is used during the cleaning process, the control method of the present invention can also be used to introduce steam into the pulping chamber during the process of discharging waste water to increase the air pressure in the pulping chamber to discharge the cleaning water more quickly. In particular, when the pulping chamber is a closed cavity, the introduced steam not only discharges the waste water more effectively, but also can clean the cavity wall compared to the prior art, and the amount of cleaning water will be less.

[0029] In addition, the control method of the present invention can also be applied to heating and boiling the pulp. When the raw pulp in the pulping chamber is discharged into the pulp receiving cup, steam is introduced into the pulping chamber, and the steam enters the pulp receiving cup through the liquid discharge component, thereby heating and boiling the raw pulp in the pulp receiving cup. Compared with the existing complex steam heating food processing machine that needs to set up an independent steam pipeline to connect to the pulp receiving cup, this solution has a simpler structure. After boiling, the consumer can directly take the pulp receiving cup to drink, which is very convenient to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention will be further described below in conjunction with the accompanying drawings:

[0031] Figure 1 This is a structural schematic diagram of a food processing machine according to a first embodiment of the present invention;

[0032] Figure 2 It is a structural schematic diagram of a food processing machine according to the second embodiment of the present invention. DETAILED DESCRIPTION

[0033] Embodiment 1:

[0034] like Figure 1 As shown, a food processor of the first embodiment of the present invention is a food processor, comprising a machine body 1, a grinding cup 2 installed in the machine body 1, and a cup cover 3 installed on the grinding cup 2, wherein the cup cover 3 is installed with a silicone plug 31, and the grinding cup 2 and the cup cover 3 enclose a non-enclosed pulping chamber. At the same time, a water tank 4 is installed on one side of the machine body 1, and a heating device (not shown in the figure) is provided in the water tank 4 to heat the water tank and generate steam, wherein a water inlet and steam inlet nozzle 21 is provided on the wall of the grinding cup 2 to let water or steam into the grinding cup 2, wherein the water inlet and steam inlet nozzle 21 is connected to the water tank 4 through a pipeline (not shown in the figure). wherein the water tank 4 and the heating device form a steam generating device for introducing steam into the pulping chamber. In addition, a drain port (not marked in the figure) is provided at the bottom of the pulverizing cup 2, and a drain assembly 5 is installed at the drain port, wherein the drain assembly 5 includes a drain pipe 51, and a pulp receiving cup 6 and a waste water box (not shown in the figure) are provided below the drain pipe 51, and the waste water box is located in the installation cavity (not shown in the figure) of the machine body 1 and is arranged side by side with the pulp receiving cup 6. For the drain pipe 51 of this embodiment, it can be rotated between the pulp receiving cup 6 and the waste water box to discharge pulp and waste water respectively.

[0035] The food processor of this embodiment has the following control method, namely: when the drain assembly is in the open state, the steam generating device continuously or intermittently introduces steam into the pulping chamber, and the steam is discharged from the pulping chamber through the drain assembly.

[0036] The above control method can be applied to sterilization and disinfection of food processing machines before pulping. When the food processing machine is powered on, the heating device heats the water in the water tank and generates steam, and the steam enters the pulping chamber from the water inlet and steam inlet nozzles. For this embodiment, the pulping chamber is a non-sealed structure, and the drainage component is the main passage for the steam. A small part of the steam will escape from the pulping chamber through the plug provided on the cup cover, while most of the steam will be directly discharged from the pulping chamber through the drainage component. On the one hand, the temperature of the steam is relatively high, and the high-temperature steam will heat the surface of the wall of the pulping chamber after filling the pulping chamber, so that the surface temperature of the wall rises rapidly, forming the effect of pasteurization and disinfection. On the other hand, when the high-temperature steam is introduced into the pulping chamber, it will quickly liquefy and condense into water droplets when it encounters the cold chamber. The water droplets slide down along the wall of the pulping chamber, and absorb mold, stains, oil stains and dust on the wall. In addition, the subsequent steam can also accelerate the downward push of the previously condensed water droplets and discharge them into the waste water box through the drainage component (the direction of the steam flow path). Therefore, for this embodiment, before pulping, steam can be used to sterilize and disinfect the pulping chamber and the drainage component.

[0037] At the same time, the control method of the food processor of this embodiment can also be applied to the discharge process of slurry. When the slurry is made, the drainage component is turned on, and the slurry in the slurry making chamber will be discharged into the slurry receiving cup through the drainage component. However, during the slurry making process, under the beating of the crushing blade, a large number of fine slurry foams will be formed on the surface of the slurry. Since the slurry foams are viscous, as the slurry is discharged, the fine slurry foams will hang on the cavity wall and cannot be discharged. In the discharge process of the slurry of this embodiment, the control method can be applied to effectively solve the problems of slurry foams hanging on the wall and slurry foams not being discharged cleanly. Because, on the one hand, the high-temperature steam introduced will condense into water droplets after encountering the cold cavity wall, and the water droplets will slide down along the cavity wall, which can wash away the fine slurry foams. In addition, after the high-temperature steam heats the slurry foam, the air in the slurry foam will expand due to the heat, which will cause the slurry foam to break. On the other hand, when steam is introduced into the slurry making chamber, the pressure in the chamber continues to increase, which will also force the slurry foam to achieve the purpose of breaking. Thereby, the broken slurry foam is transformed into a flowing slurry that is gathered on the bottom wall of the cavity and flows into the slurry receiving cup through the drainage component. At the same time, when the pressure in the chamber increases, the discharge of the slurry will be accelerated, the efficiency of the discharge will be improved, and the time required for slurrying will be reduced.

[0038] It should be noted that, in this embodiment, the slurry is a slurry without pulp residue or with a small amount of pulp residue. After the slurry is stirred by the crushing blade, it is evenly mixed and has good fluidity. When the drainage component is opened, the slurry can be easily discharged into the pulp receiving cup, so that the slurry or pulp residue is rarely discharged cleanly. It should also be noted that, in this embodiment, steam can be introduced into the pulping chamber before discharging the pulp and before opening the drainage component to increase the pressure in the pulping chamber, improve the subsequent slurry discharge efficiency, and reduce the time of pulping and pulping.

[0039] Secondly, for this embodiment, when the slurry produced is raw slurry, after the slurry is discharged, the control method of this embodiment can also be applied to heat and boil the raw slurry in the slurry cup. At this time, a steam connecting pipe can be provided on the discharge pipe to directly extend into the slurry cup, and the steam entering the slurry making chamber will enter the slurry cup through the discharge assembly, the discharge pipe and the steam connecting pipe, thereby steam heating and boiling the raw slurry in the slurry cup. The steam-heated slurry in this embodiment will not cause the problem of sticky bottom, and can largely retain the nutrients of the slurry without loss. In addition, the steam-heated slurry in this embodiment has a simple structure. Compared with the prior art, after boiling, the consumer can directly take away the slurry cup for drinking, which is very convenient to operate.

[0040] In addition, for this embodiment, the control method can also be applied to the cleaning of the pulping chamber after pulping. The high-temperature steam introduced into the pulping chamber will liquefy and condense into water droplets. The condensed water droplets will flush the cavity wall under the action of gravity, and at the same time absorb the residue on the cavity wall, and discharge it into the waste water box through the drainage component. Compared with the existing soybean milk machine that can be realized without hand washing, the pulping chamber can be cleaned by opening the drainage component and continuously passing steam for cleaning. At the same time, it should be noted that compared with the above-mentioned patent application CN201910481587.5, the pulp residue adhered to the cavity wall of the pulping chamber in this embodiment has not been left for a long time to dry, and the adhesion is small, and no special infiltration and steam softening are required. Because the step of using steam to clean the cavity wall of the pulping chamber is carried out after the pulping is completed, at this time, the cavity wall is still in a humid environment. After the steam condenses into water droplets, the pulp residue adhered to the cavity wall can be easily washed off.

[0041] Even though the cleaning process of this embodiment includes the step of introducing water into the pulping chamber for cleaning, the control method of this embodiment can also be used in the process of discharging waste water. Steam can be introduced into the pulping chamber to increase the air pressure in the pulping chamber to more quickly discharge the cleaning water into the waste water box. The introduced steam not only discharges the waste water more effectively, but also can clean the cavity wall compared to the prior art, and the amount of water used for cleaning and the number of water intakes will be less.

[0042] Embodiment 2:

[0043] like Figure 2 The figure is a schematic diagram of the structure of the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: in this embodiment, the cup cover has no air holes and silicone plugs, and the pulping chamber formed by the cup cover and the crushing cup is a closed structure. When steam is introduced into the pulping chamber, the drain assembly is the only outlet for steam to be discharged.

[0044] The food processor of this embodiment can prepare thick soybean milk. The pulping process has the following steps:

[0045] 1) Preparation

[0046] 2) Pulping stage: The crushing blade beats and crushes the mixture of material and water in the pulping chamber to prepare a concentrated raw pulp mixed with pulp juice and pulp residue.

[0047] 3) Juice discharge stage: Open the drainage component, and the juice and the pulp residue mixed with the juice are discharged from the drainage component into the pulp receiving cup.

[0048] 4) Slag discharge stage: The drainage component remains open, and the remaining slurry is discharged from the drainage component into the slurry receiving cup.

[0049] 5) Cleaning stage: The pulping chamber is cleaned and the cleaned water is discharged by the drainage component.

[0050] 6) Boiling stage: Heat and boil the raw pulp in the pulp cup until it is cooked.

[0051] Similar to the first embodiment, in the preparation stage of the pulping process of this embodiment, the drainage assembly is opened, and then steam is passed into the pulping chamber to sterilize and disinfect the pulping chamber. The principle is the same as that of the first embodiment, and will not be repeated here.

[0052] Moreover, for this embodiment, since the prepared slurry is a thick slurry, the fluidity of the thick slurry is poor. When the drainage component is opened, the slurry with good fluidity and a part of the slurry residue evenly mixed with the slurry can be discharged to the slurry receiving cup through the drainage component. As the slurry in the pulping chamber becomes less and less, the accumulated slurry residue will be difficult to be discharged from the drainage component. Since the slurry residue in the raw slurry is also rich in nutrients, if it cannot be discharged into the slurry receiving cup for cooking together, it will cause a great waste, and the slurry residue remaining in the pulping chamber is also difficult to clean. In the prior art, water is generally added multiple times to flush the slurry residue into the slurry receiving cup. This not only requires multiple water additions to flush the residue, but also the slurry concentration in the slurry receiving cup will be greatly diluted after multiple flushings, which cannot meet the requirements of consumers who like the taste of thick slurry.

[0053] In this embodiment, the above control method can also be applied in the juice discharge stage, that is, when the liquid discharge component is in the open state, the steam generating device introduces steam into the pulping chamber, and the steam discharges the pulp into the pulp receiving cup through the liquid discharge component. Similar to the first embodiment, the introduction of steam in the juice discharge stage can well break up and flush the pulp foam on the surface of the cavity wall, and at the same time, accelerate the discharge efficiency of the pulp.

[0054] It should be noted that in this embodiment, the pulping chamber is a closed structure, and the pulp gravity drainage is slow, and the pulp cannot be naturally discharged in the latter stage of the drainage. Therefore, during the drainage process, steam is continuously or intermittently introduced to increase the pressure in the pulping chamber, and the steam pressure is used to accelerate the drainage of the pulp. In addition, while steam is used to drain the juice, the steam will also condense into water droplets on the cavity wall, further washing off the pulp residue, pulp foam, and residue on the cavity wall.

[0055] At the same time, the control method can also be applied to the slag discharge stage. Since the slurry prepared by the food processor is raw slurry without boiling, no matter whether the slurry is in the juicing stage or the slag discharge stage, the high-temperature steam introduced will heat the slurry with good fluidity, so that the slurry mixed with the slag will be heated in the pulping chamber to form a large amount of foam and wrap the slag. Since the slag is wrapped by the foam, the fluidity of the slag is greatly improved, and the foam with good fluidity drives the slag to be discharged into the slurry receiving cup through the drainage component. Therefore, in this embodiment, even if water is not introduced into the pulping chamber to flush the slag during the slag discharge process, the slag can be discharged through the drainage component under the action of steam after a certain period of time.

[0056] It should be noted that, for this embodiment, in order to speed up the efficiency and time of slag discharge, a step of introducing water into the pulping chamber to flush the slag can be set after the juice discharge stage and before the slag discharge stage. In addition, the step of introducing water to flush the slag can also be set during the slag discharge process, that is, the simultaneous introduction of water and steam. Of course, for the slag flushing step of this embodiment, the number of slag flushing is obviously less than the multiple slag flushing times of the prior art, and in this embodiment, the water intake and steam intake may not be synchronized. At the same time, in order to speed up the efficiency of slag discharge, a pressurization stage can also be set after the juice discharge stage and before the slag discharge stage, that is: the drainage component is closed, and the steam generating device continuously or intermittently introduces steam into the pulping chamber for pressurization. Since the pulping chamber is a sealed structure, when the pressurization stage is completed and the slag discharge stage is entered, under the action of pressure, the steam will drive the pulp slag through the drainage component into the pulp receiving cup.

[0057] It should also be noted that, in the present embodiment, steam can also be continuously or intermittently introduced only during the juice discharge process to accelerate the discharge of the pulp. Of course, in the present embodiment, for consumers who do not like the feeling of residue in their drinks, the pulp residue discharged by the drainage component can also be controlled to be directly discharged into the wastewater box during the residue discharge stage to achieve preliminary filtration of the pulp residue. Similarly, it should also be noted that, compared with the above-mentioned patent application CN201910481587.5, the pulp residue adhered to the wall of the pulping chamber in this embodiment has not been left to dry for a long time, and the adhesion force is relatively small, and no special infiltration and steam softening are required. Because the step of using steam to discharge the pulping chamber is carried out after the juice discharge is completed, and the pulping chamber is a closed structure, the pulping chamber is always in a humid environment, and the pulp residue adhered to the wall of the cavity is always in a moist and softened state. Therefore, when the steam condenses into water droplets, the pulp residue adhered to the cavity wall can be easily washed off.

[0058] Secondly, for this embodiment, the above control method can also be applied for cleaning during the cleaning stage, so that the residues and stains on the cavity wall can be washed clean by the water droplets condensed by steam, and then the accumulated waste water can be discharged to the waste water box. The principle and process of applying the above control method in the cleaning stage are the same as those in Example 1, and will not be repeated here. It should be noted that during the cleaning process, the condensed water discharged by the drainage component can also be directly discharged into the slurry receiving cup to mix and blend the raw concentrated slurry. Since the amount of condensed water discharged is small, the concentration of the slurry will not be greatly reduced. Therefore, if the condensed water discharged during the cleaning stage can be discharged into the slurry receiving cup for blending, the food processor of this embodiment can remove the waste water box. In this way, the structure of the food processor will be simpler and the manufacturing cost will be lower.

[0059] In addition, for this embodiment, as in the first embodiment, the above control method can also be applied in the boiling stage, using the steam introduced into the pulping chamber to heat and boil the raw pulp in the pulp cup until it is cooked.

[0060] It should be noted that, for the food processor of the present invention, the steam generated by the steam generating device may be high-purity steam. However, since part of the steam will immediately liquefy into water mist or water droplets when the steam is ejected from the water inlet and steam inlet nozzle, the steam of the present embodiment may also be a mixture of steam and water.

[0061] The food processor of the present invention may be a wall-breaking food processor with a motor placed below, or a food processor of a frame structure. 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.
