Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more specifically, to an air conditioner control method and an air conditioner. Background Technology

[0002] With the rapid development of home appliance technology, the concept of comfort design for air conditioning products has gradually been put on the agenda. End users have high demands for the comfort and fresh air function of air conditioners. In order to avoid condensation dripping and causing poor user experience or even complaints, existing products generally adopt various anti-condensation measures or structural improvements, such as adjusting the angle of the air guide plate or controlling the fan speed by detecting the humidity or temperature of the air outlet to prevent condensation.

[0003] However, when solving the problem of condensation in fresh air, the anti-condensation measures in related technologies usually cause a loss of overall performance (such as lowering the speed, raising the set temperature, etc.) and are likely to result in a poor user experience (users may mistakenly think that the air conditioner is out of control when they suddenly perceive that the wind speed or the air deflector is adjusting on its own). Summary of the Invention

[0004] To address the issue of poor user comfort when using the fresh air function of air conditioners due to condensation during fresh air intake, this invention provides a control method for an air conditioner. The control method includes: determining whether the air conditioner's fresh air function is activated; and, if the fresh air function is activated, acquiring the indoor unit's ambient temperature value, denoted as t. n After acquiring the indoor unit ambient temperature value for a first period of time, the indoor unit ambient temperature value is updated, and t is recorded as t. n =t n+1 The system controls the indoor fan speed, air guide angle, and set temperature based on the indoor unit ambient temperature, whether there are users in the target area, and whether the air conditioner has its swing function activated, in order to prevent condensation from occurring in the indoor unit of the air conditioner.

[0005] Compared with existing technologies, the technical effect achieved by this solution is as follows: After the air conditioner activates its fresh air function, by acquiring the indoor unit's ambient temperature value, it is possible to determine whether there is a risk of condensation in the indoor unit. The indoor unit's ambient temperature value is updated after a first period of time, and this is recorded as t. n =t n+1This design ensures that the indoor unit ambient temperature value acquired after the first time interval overwrites the previous value, preventing the storage of too many indoor unit ambient temperature values ​​from doubling the data volume, increasing program processing time and code processing volume, thus shortening program processing time and improving data processing efficiency. By controlling the indoor fan speed, air guide angle, and set temperature based on the indoor unit ambient temperature value, whether there are users in the target area, and whether the air conditioner's swing function is activated, condensation is prevented on the indoor unit. This allows for intelligent and precise adjustment of the air guide angle and flexible control of the indoor fan speed, thereby improving user comfort while preventing condensation. Ultimately, it achieves a truly humanized and comfortable anti-condensation fresh air system.

[0006] In one embodiment of the present invention, the step of controlling the indoor fan speed, air guide angle, and set temperature of the air conditioner based on the indoor unit ambient temperature value, whether there is a user in the target area, and whether the air conditioner has its swing function activated includes: determining whether the indoor unit ambient temperature value meets a first preset condition; if so, controlling the indoor fan speed, air guide angle, and set temperature of the air conditioner based on whether there is a user in the target area and whether the air conditioner has its swing function activated; wherein, the first preset condition includes: t n ≤T 凝露 ;t n This refers to the indoor unit ambient temperature; T 凝露 This is the preset dew point temperature.

[0007] Compared to existing technologies, the technical effect achieved by this solution is: It is understandable that condensation will form when the air temperature drops to the dew point temperature. If t n ≤T 凝露 This indicates that the current indoor unit ambient temperature is relatively low, meeting the dew point temperature requirement. Condensation is highly likely to occur in the indoor unit, requiring appropriate measures to prevent it. By controlling the indoor fan speed, air deflector angle, and set temperature based on whether users are present in the target area and whether the air conditioner's swing function is activated, corresponding anti-condensation measures can be selected. This allows for the rapid elimination of condensation without affecting the user experience.

[0008] In one embodiment of the present invention, before determining whether the indoor unit ambient temperature value meets the first preset condition, the control method of the air conditioner further includes: determining t n >t n+1If the condition is met, determine whether the indoor unit ambient temperature value meets the first preset condition; if not, repeatedly execute the step of updating the indoor unit ambient temperature value after obtaining the indoor unit ambient temperature value for a first time duration, and record t. n =t n+1 operate.

[0009] Compared to existing technologies, the technical effects achieved by this solution are as follows: Understandably, the temperature trend is downward in cooling mode. If an abnormal temperature rise occurs, it indicates a possible temperature surge caused by factors such as the introduction of fresh air, the entry or movement of people. Considering that such factors reduce the risk of condensation, before determining whether the indoor unit's ambient temperature meets the first preset condition, the program processes and removes abnormal temperatures, essentially moving the next data point forward.

[0010] In one embodiment of the present invention, the step of controlling the indoor fan speed, air guide angle and set temperature of the air conditioner based on whether there is a user in the target area and whether the air conditioner has activated the air swing function includes: activating the spatial human body recognition device to detect whether there is a user in the target area; if there is a user in the target area, controlling the indoor fan speed, air guide angle and set temperature of the air conditioner based on whether the air swing function of the air conditioner has activated.

[0011] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by activating the spatial human body recognition device, it can detect whether there are users in the target area, and select different anti-condensation measures according to whether there are users in the target area, so as to avoid misunderstandings caused by changes in air guides or wind speed.

[0012] In one embodiment of the present invention, if there is a user in the target area, controlling the indoor fan speed, air guide plate angle, and set temperature of the air conditioner according to whether the air conditioner has its swing function activated includes: if the air conditioner has its swing function activated, increasing the indoor fan speed, controlling the air guide plate angle to the currently set air guide plate angle, and controlling the set temperature to the currently set temperature; if the air conditioner has not activated its swing function, increasing the set temperature, controlling the indoor fan speed to the currently set indoor fan speed, and controlling the air guide plate angle to the currently set air guide plate angle.

[0013] Compared to existing technologies, the technical effects achieved by this solution are as follows: It is understandable that when users are present in the target area, they are highly likely to perceive differences in the air conditioning's output, and changes in the air deflector or airflow speed can easily lead to user misunderstanding. Since the swing function itself involves changes in airflow direction and speed, activating the air conditioner's swing function reduces discomfort caused by the program's automatic airflow adjustment. Therefore, when the air conditioner's swing function is activated, it is suitable to prevent condensation by adjusting the indoor fan speed. This involves controlling the air conditioner to increase the indoor fan speed, maintain the air deflector angle at the currently set angle, and maintain the set temperature at the currently set temperature. Increasing the indoor fan speed quickly eliminates condensate and prevents condensation. When the air conditioner's swing function is not activated, adjusting the indoor fan speed or changing the air deflector angle can easily cause user misunderstanding. Therefore, a set temperature adjustment method is used. By increasing the set temperature, the refrigerant circulation is controlled, thereby changing the evaporator coil temperature and indirectly regulating the evaporator temperature to prevent condensation from forming in the indoor unit.

[0014] In one embodiment of the present invention, the control method of the air conditioner further includes: if there are no users in the target area, increasing the speed of the indoor fan, increasing the angle of the air guide plate, and controlling the set temperature to the current set temperature.

[0015] Compared with existing technologies, the technical effects achieved by this solution are as follows: when there are no users in the target area, changes in the air guide plate or wind speed will not cause user misunderstanding and lead to a poor user experience. Therefore, by combining increasing the internal fan speed with increasing the angle of the air guide plate, condensation can be quickly eliminated and condensation can be avoided.

[0016] In one embodiment of the present invention, the increase in the internal fan speed when there are no users in the target area is greater than the increase in the internal fan speed when there are users in the target area.

[0017] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: when there are no users in the target area, condensation can be reduced with maximum efficiency; when there are users in the target area, although the air conditioner's swing function will reduce the discomfort caused by the program's autonomous adjustment of the fan speed, it cannot be completely eliminated. Therefore, the increase in the indoor fan speed when there are no users in the target area is greater than the increase in the indoor fan speed when there are users in the target area.

[0018] This invention provides an air conditioner that implements any of the control methods described above. The air conditioner includes: a judgment module for judging whether the air conditioner has its fresh air function activated; and an acquisition module for acquiring the indoor unit ambient temperature value, denoted as t, when the fresh air function is activated. nThe update module is used to update the indoor unit ambient temperature value after a first time interval following the acquisition of the indoor unit ambient temperature value, denoted as t. n =t n+1 The control module is used to control the indoor fan speed, air guide angle, and set temperature of the air conditioner based on the indoor unit ambient temperature value, whether there are users in the target area, and whether the air conditioner has activated the air sweep function, in order to avoid condensation in the indoor unit of the air conditioner.

[0019] This invention provides an air conditioner, which includes a controller for executing an executable program to implement any of the control methods for an air conditioner as described above.

[0020] By adopting the technical solution of the present invention, the following technical effects can be achieved:

[0021] (1) After the air conditioner turns on its fresh air function, by acquiring the indoor unit's ambient temperature value, it is possible to determine whether there is a risk of condensation in the indoor unit. The indoor unit's ambient temperature value is updated after a first period of time following acquisition, and this is recorded as t. n =t n+1 This design ensures that the indoor unit ambient temperature value acquired after the first time interval overwrites the previous value, preventing the storage of too many indoor unit ambient temperature values ​​from doubling the data volume, increasing program processing time and code processing volume, thus shortening program processing time and improving data processing efficiency. By controlling the indoor fan speed, air guide angle, and set temperature based on the indoor unit ambient temperature value, whether there are users in the target area, and whether the air conditioner's swing function is activated, condensation is prevented on the indoor unit. This allows for intelligent and precise adjustment of the air guide angle and flexible control of the indoor fan speed, thereby improving user comfort while preventing condensation. Ultimately, it achieves a truly humanized and comfortable anti-condensation fresh air system.

[0022] (2) When users are present in the target area, they are very likely to perceive differences in the air conditioning output. Changes in the air deflector or air speed can easily cause misunderstandings. Since the swing function itself involves changes in air direction and speed, the swing function of the air conditioner reduces the discomfort caused by the program's automatic adjustment of air speed. Therefore, when the swing function of the air conditioner is on, it is appropriate to avoid condensation by adjusting the indoor fan speed. Thus, by increasing the indoor fan speed, adjusting the air deflector angle to the currently set angle, and adjusting the set temperature to the currently set temperature, the condensate can be quickly eliminated by increasing the indoor fan speed, thus preventing condensation. When the air conditioner's swing function is not on, adjusting the indoor fan speed or changing the air deflector angle can easily cause misunderstandings. Therefore, the set temperature adjustment method is adopted. By increasing the set temperature, the refrigerant circulation is controlled, thereby changing the temperature of the evaporator coil, which indirectly regulates the evaporator temperature and prevents condensation from forming in the indoor unit.

[0023] (3) When there are no users in the target area, changes in the air guide plate or wind speed will not cause users to misunderstand and lead to a poor user experience. Therefore, by combining increasing the speed of the internal fan with increasing the angle of the air guide plate, condensation can be quickly eliminated and condensation can be avoided.

[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] See Figure 1 This is a flowchart illustrating a control method for an air conditioner provided by the present invention. The control method includes, for example, the following steps: determining whether the air conditioner has its fresh air function activated; and, if the fresh air function is activated, acquiring the indoor unit ambient temperature value, denoted as t. n After acquiring the indoor unit ambient temperature value for a first period of time, the indoor unit ambient temperature value is updated, and t is recorded as t. n =t n+1 The system controls the indoor fan speed, air deflector angle, and set temperature based on the indoor unit's ambient temperature, the presence of users in the target area, and whether the air conditioner's air swing function is activated, in order to prevent condensation from forming on the indoor unit. For example, this first duration is 3 seconds. If the air conditioner's fresh air function is not activated, the air conditioner operates according to the user's currently set function mode.

[0040] In one specific embodiment, the program controls the CPU main chip to access dedicated storage space to store the indoor ambient temperature values ​​collected by the indoor ambient temperature sensor. The program-controlled temperature acquisition method is as follows: the program acquires one temperature value every 1 second, continuously obtaining three temperature values ​​for Δt (considering CPU computation and AD register usage, the program is generally set to read port data once every 5ms; Δt is chosen as 3s here). The average of the three temperature values ​​is calculated and set as t1. Then, after a 3-second interval, a second set of average temperature values ​​t2 is acquired, and this process is continuously acquired for 1 minute: t3, t4, t5…t…10 (One data point is acquired every 6 seconds, 10 temperature data points are acquired within 1 minute). When acquiring subsequent data, the first data point is discarded, and each subsequent data point overwrites the previous one, following the sequence: t1 = t2, t2 = t3, ... t 10 =t 11 .

[0041] Understandably, after the air conditioner activates its fresh air function, acquiring the indoor unit's ambient temperature value allows for assessment of the risk of condensation within the unit. The indoor unit's ambient temperature value is updated after a first period of time, and this is recorded as t. n =t n+1 This design ensures that the indoor unit ambient temperature value acquired after the first time interval overwrites the previous value, preventing the storage of too many indoor unit ambient temperature values ​​from doubling the data volume, increasing program processing time and code processing volume, thus shortening program processing time and improving data processing efficiency. By controlling the indoor fan speed, air guide angle, and set temperature based on the indoor unit ambient temperature value, whether there are users in the target area, and whether the air conditioner's swing function is activated, condensation is prevented on the indoor unit. This allows for intelligent and precise adjustment of the air guide angle and flexible control of the indoor fan speed, thereby improving user comfort while preventing condensation. Ultimately, it achieves a truly humanized and comfortable anti-condensation fresh air system.

[0042] Furthermore, the step of controlling the indoor fan speed, air guide angle, and set temperature of the air conditioner based on the indoor unit ambient temperature value, whether there is a user in the target area, and whether the air conditioner has its swing function activated includes: determining whether the indoor unit ambient temperature value meets a first preset condition; if so, controlling the indoor fan speed, air guide angle, and set temperature of the air conditioner based on whether there is a user in the target area and whether the air conditioner has its swing function activated; wherein, the first preset condition includes: t n ≤T 凝露 ;t n This refers to the indoor unit ambient temperature; T 凝露 Here, T represents the preset dew point temperature; n is a positive integer less than 10. It should be noted that different cooling capacities correspond to different temperatures (T0). 凝露 The results may vary; the actual experimental results of the specific model will prevail.

[0043] It is understandable that condensation will form when the air temperature drops to the dew point. If t n ≤t 凝露This indicates that the current indoor unit ambient temperature is relatively low, meeting the dew point temperature requirement. Condensation is highly likely to occur in the indoor unit, requiring appropriate measures to prevent it. By controlling the indoor fan speed, air deflector angle, and set temperature based on whether users are present in the target area and whether the air conditioner's swing function is activated, corresponding anti-condensation measures can be selected. This allows for the rapid elimination of condensation without affecting the user experience.

[0044] Furthermore, before determining whether the indoor unit ambient temperature value meets the first preset condition, the air conditioner control method further includes: determining t n >t n+1 If the condition is met, determine whether the indoor unit ambient temperature value meets the first preset condition; if not, repeatedly execute the step of updating the indoor unit ambient temperature value after obtaining the indoor unit ambient temperature value for a first time duration, and record t. n =t n+1 operate.

[0045] Understandably, the temperature should be decreasing in cooling mode. If the temperature rises abnormally, it indicates a possible temperature jump caused by factors such as the introduction of fresh air, the entry or movement of people. Considering that such factors reduce the risk of condensation, the program first processes and removes abnormal temperatures before determining whether the indoor unit's ambient temperature meets the first preset condition; that is, it moves the next data point forward.

[0046] Furthermore, the step of controlling the air conditioner's indoor fan speed, air deflector angle, and set temperature based on whether a user is present in the target area and whether the air conditioner's swing function is activated includes: activating a spatial human body recognition device to detect whether a user is present in the target area; if a user is present in the target area, then controlling the air conditioner's indoor fan speed, air deflector angle, and set temperature based on whether the air conditioner's swing function is activated. Here, the target area refers to the area where users can easily perceive changes in the airflow from the air conditioner. For example, this spatial human body recognition device can be an infrared light sensor.

[0047] Understandably, by activating the spatial human body recognition device, the presence of users in the target area can be detected, and different anti-condensation measures can be selected based on whether users are present in the target area, so as to avoid misunderstandings caused by changes in air guides or wind speed.

[0048] Furthermore, if a user exists within the target area, controlling the indoor fan speed, air guide plate angle, and set temperature of the air conditioner based on whether the air conditioner's swing function is activated includes: if the air conditioner's swing function is activated, increasing the indoor fan speed, controlling the air guide plate angle to the currently set angle, and controlling the set temperature to the currently set temperature; if the air conditioner's swing function is not activated, increasing the set temperature, controlling the indoor fan speed to the currently set speed, and controlling the air guide plate angle to the currently set angle. When the air conditioner's swing function is activated, the indoor motor drives the air guide plate to swing.

[0049] Understandably, when users are present in the target area, they are highly likely to perceive differences in the air conditioning's airflow. Changes in the air deflector or airflow speed can easily lead to misunderstandings. Since the swing function itself involves changes in airflow direction and speed, activating the swing function reduces discomfort caused by automatically adjusted airflow. Therefore, when the swing function is active, adjusting the indoor fan speed is suitable to prevent condensation. This involves increasing the indoor fan speed, setting the air deflector angle to the current setting, and maintaining the set temperature. Increasing the indoor fan speed quickly eliminates condensation and prevents condensation. When the swing function is not activated, adjusting the indoor fan speed or changing the air deflector angle can easily mislead users. Therefore, setting the temperature is used to control refrigerant circulation and thus change the evaporator coil temperature, indirectly regulating the evaporator temperature and preventing condensation in the indoor unit.

[0050] Furthermore, the control method of the air conditioner also includes: if there are no users in the target area, increasing the speed of the indoor fan, increasing the angle of the air guide plate, and controlling the set temperature to the current set temperature.

[0051] Understandably, when no users are present in the target area, changes in the air guide vane or airflow speed will not cause user misunderstanding or lead to a poor user experience. Therefore, by combining increasing the internal fan speed with increasing the angle of the air guide vane, the condensate on the lower inner wall of the air guide structure is quickly evaporated (condensate on the upper wall of the air guide structure generally flows down the structure and does not drip), thus preventing condensation. The purpose of adjusting the angle of the air guide vane is to rapidly evaporate and remove condensation from the lower inner wall of the air guide structure.

[0052] Furthermore, the increase in the internal fan speed when there are no users in the target area is greater than the increase in the internal fan speed when there are users in the target area.

[0053] It is understandable that when there are no users in the target area, condensation can be reduced with maximum efficiency; when there are users in the target area, although the air conditioner's swing function will reduce the discomfort caused by the program's automatic adjustment of the fan speed when it is turned on, it cannot be completely eliminated. Therefore, the increase in the indoor fan speed when there are no users in the target area is greater than the increase in the indoor fan speed when there are users in the target area.

[0054] In one specific embodiment, if t n ≤t 凝露 If the ambient temperature of the indoor unit meets the dew point temperature requirement, the indoor unit is prone to condensation. Therefore, the controller CPU activates the infrared light sensor to detect whether a user is present in the target area. If a user is present in the target area, it further determines whether the air conditioner should activate the air swing function.

[0055] If there are users in the target area and the air conditioner's swing function is activated, then set the indoor fan speed to V1 (V1>1.3*V). 设定 V 设定 Set the current fan speed for the air conditioner and the angle of the air guide vane to θ1 (θ1 = θ). 设定 θ 设定 Set the air guide vane angle for the air conditioner and set the temperature to Φ1 (Φ1 = Φ). 设定 Φ 设定 (The current set temperature).

[0056] If there are users in the target area and the air conditioner's swing function is not activated, then set the indoor fan speed to V2 (V2 = V 设定 V 设定 Set the current fan speed for the air conditioner and the angle of the air guide vane to θ2 (θ2 = θ). 设定 θ 设定 Set the air guide vane angle for the air conditioner and set the temperature to Φ2 (Φ2 = Φ). 设定 +1℃, Φ 设定 (This refers to the current set temperature). The Φ2 value is only used for CPU processing; the actual displayed set temperature is still Φ2. 设 Certainly.

[0057] If no users exist in the target area, set the internal fan speed to V3 (V3 > 1.5 * V). 设定 V 设定 Set the current fan speed for the air conditioner and the angle of the air guide vane to θ3 (θ3 = θ). 设定 +5°, θ 设定 Set the air guide vane angle for the air conditioner and set the temperature to Φ3 (Φ3 = Φ). 设定 Φ 设定(This is the current set temperature). The 5° angle is defined for illustrative purposes only. Due to different structural limitations, the angle is not specifically limited and is intended to be illustrative. In addition, the purpose in this case is to achieve efficient condensation treatment. The change in the air sweep angle has been shown in the section on whether the air sweep function is enabled, so it will not be elaborated here. Furthermore, this implementation does not require consideration of the internal heating or cooling system.

[0058] Furthermore, the present invention provides an air conditioner 200, which includes, for example, a judgment module 210, an acquisition module 220, an update module 230, and a control module 240. The judgment module 210 is used to determine whether the air conditioner has its fresh air function activated; the acquisition module 220 is used to acquire the indoor unit ambient temperature value, denoted as t, when the air conditioner has its fresh air function activated. n The update module 230 is used to update the indoor unit ambient temperature value after acquiring the indoor unit ambient temperature value for a first period of time, denoted as t. n =t n+1 The control module 240 is used to control the indoor fan speed, air guide plate angle and set temperature of the air conditioner according to the indoor unit ambient temperature value, whether there is a user in the target area, and whether the air conditioner has the air sweep function turned on, so as to avoid condensation in the indoor unit of the air conditioner.

[0059] In one specific embodiment, the judgment module 210, the acquisition module 220, the update module 230, and the control module 240 cooperate with each other to enable the air conditioner 200 to implement any of the control methods of the air conditioner described above and achieve the same effect. To avoid repetition, they will not be described again here.

[0060] Furthermore, the present invention provides an air conditioner, the air conditioner comprising: a controller, the controller being configured to execute an executable program to implement any of the control methods of the air conditioner described above, and to achieve the same effect, which will not be repeated here to avoid repetition.

[0061] Furthermore, the present invention provides an air conditioner. An air outlet 13 is formed between the upper wall 11 and lower wall 12 of the air outlet of the air conditioner 100. A sweeping blade 20 is angle-adjustably disposed at the air outlet 13 via a sweeping blade drive shaft 21. The air conditioner 100 also includes an upper limit post 31 and a lower limit post 32 for limiting the swing angle of the sweeping blade 20. The sweeping blade 20 can swing up and down between the upper limit post 31 and the lower limit post 32, preventing the sweeping blade 20 from rubbing against the upper wall 11 and lower wall 12 of the air outlet during swinging.

[0062] In one specific embodiment, combined with Figures 5 to 12The angle AOB formed by the line connecting the upper limit post 31 of the sweeping blade and the rotating shaft of the sweeping blade 20, and the line connecting the lower limit post 32 of the sweeping blade and the rotating shaft of the sweeping blade 20, is defined as θ, i.e., the limit sweeping angle. The program typically sets the sweeping angle range of the guide vane to θ1; θ1 ≤ θ. Figure 8 This is a schematic diagram showing the air sweeping blades 20 in a stationary sweeping state when the air sweeping function of the air conditioner 100 is not activated. Figure 9 for Figure 8 The diagram shows the sweeping blade 20 after rotating 5° clockwise. By controlling the sweeping blade 20 to rotate downwards clockwise by 5°, the flow velocity at the lower side of the air outlet can be increased, resulting in rapid evaporation of condensation.

[0063] Combination Figure 10 Angle AOB is defined as θ, angle COC' is defined as θ1, and D is the position of the sweeping blade 20; Figure 11 A simplified schematic diagram of the sweeping blade 20 rotating 5° clockwise downwards from the fixed sweeping state. Figure 12 This is a simplified diagram illustrating the increase of the swing range of the sweeping blade 20 by 5° during dynamic sweeping. When the air conditioner 100 activates the sweeping function, the normal sweeping range of the sweeping blade 20 is COC'. With OB as the 0° reference line and the angle of COC' as θ1, when the swing range of the sweeping blade 20 increases by 5°, the lower limit OC increases clockwise downwards by 2.5°, and the upper limit OC' increases counterclockwise upwards by 2.5°. When the air conditioner 100 activates the sweeping function, increasing the sweeping range, i.e., increasing the angle of COC', facilitates the rapid evaporation of condensate on the lower wall of the air outlet.

[0064] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
