[0049] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0050] The embodiment of the present invention provides an air conditioner. In this embodiment, the air conditioner is a cabinet air conditioner. In other embodiments, the air conditioner may also be a wall-mounted air conditioner, a window air conditioner, a ceiling air conditioner or other types of air conditioners.

[0051] In the embodiment of the present invention, refer to Figures 1 to 3 The air conditioner includes a fresh air device 2 and a control device 1 . The fresh air device 2 is connected to the control device 1 . The control device 1 can be used to control the operation of the fresh air device 2 .

[0052] Reference Figure 1 and Figure 2 The air conditioner includes a housing 100, which is provided with a fresh air inlet 103, a fresh air outlet 104, an indoor return air outlet 101 and an indoor air outlet 102. The fresh air outlet 104, the indoor return air outlet 101 and the indoor air outlet 102 are all connected to the indoor environment. An indoor air duct 105 and a fresh air duct 106 are isolated and arranged in the housing 100. The indoor air duct 105 is connected to the indoor return air outlet 101 and the indoor air outlet 102, and the fresh air duct 106 is connected to the fresh air inlet 103 and the fresh air outlet 104. The indoor air duct 105 is provided with an indoor heat exchanger 200 and an indoor fan 300. When the indoor fan 300 is turned on, it can drive the indoor air to enter the indoor air duct 105 from the indoor return air outlet 101 and then be blown into the indoor environment from the indoor air outlet 102 after heat exchange with the indoor heat exchanger 200. The fresh air device 2 is disposed in the fresh air duct 106 . When the fresh air device 2 is turned on, outdoor fresh air can enter the room from the fresh air inlet 103 through the fresh air duct 106 .

[0053] In other embodiments, the fresh air outlet 104 may not be provided on the housing 100 , and the outlet of the fresh air duct 106 is connected to the indoor air duct 105 .

[0054] The fresh air device 2 includes a fresh air damper 22 and / or a fresh air fan 21, etc. When the fresh air fan 21 is turned on, it drives the outdoor fresh air to flow through the fresh air duct 106 into the indoor environment. When the fresh air fan 21 is turned off, it stops driving the outdoor fresh air to flow through the fresh air duct 106 into the indoor environment. The operating speed of the fresh air fan 21 is different, and the corresponding amount of fresh air introduced is different. The fresh air damper 22 is rotatably installed in the fresh air duct 106. The wind shielding angle of the fresh air damper 22 is different, and the corresponding amount of fresh air introduced is different. Among them, the wind shielding angle is specifically the angle between the fresh air damper 22 and the direction of the fresh air air flow. When the angle is 0, the fresh air volume is the largest, and when the angle is 90 degrees, the fresh air volume is the smallest. In this embodiment, the minimum fresh air volume is 0, and in other embodiments, the minimum fresh air volume may also be greater than 0.

[0055] Further, see Figure 2 A dehumidification module 3 may also be provided in the fresh air duct 106 to dehumidify the fresh air entering the indoor environment.

[0056] In this embodiment, the dehumidification module 3 includes a semiconductor refrigeration module 31 and a coil 32 connected to the semiconductor refrigeration module 31 for heat exchange, and the coil 32 is filled with refrigerant. Specifically, the semiconductor refrigeration module 31 is connected to the coil 32 for heat exchange through a cold plate (for example, a structure made of a material with good thermal conductivity such as aluminum or copper). In this embodiment, the semiconductor refrigeration module 31 is arranged on the top of the coil 32. When the semiconductor refrigeration module 31 is turned on, the refrigerant temperature at the top decreases and then settles downward, which can quickly cool down the entire coil 32. The moisture in the fresh air flowing through the coil 32 can condense on the surface of the coil 32, and the humidity of the fresh air after heat exchange with the coil 32 is reduced.

[0057] In other embodiments, the dehumidification module 3 may also be configured as other types of modules with dehumidification functions, such as a structure made of dehumidification materials.

[0058] Further, see Figure 2 The air conditioner may further include a fresh air heating module 4 disposed in the fresh air duct 106. When the fresh air heating module 4 is turned on, the fresh air entering may be heated to prevent the temperature of the fresh air sent into the indoor environment from being too low.

[0059] Further, see Figures 1 to 3 The air conditioner may further include a humidity detection module 400, which is used to detect the indoor environment humidity and the outdoor environment humidity. The humidity detection module 400 is connected to the control device 1. The humidity detection module 400 includes a first humidity sensor and a second humidity sensor. The first humidity sensor may be arranged indoors (e.g., at the indoor return air outlet 101) to detect the indoor environment humidity; the second humidity sensor may be arranged outdoors or at the fresh air inlet 103 to detect the outdoor environment humidity.

[0060] Further, see Figure 1 and Figure 3 The air conditioner may further include a temperature detection module 500, which is used to detect the indoor environment temperature. The temperature detection module 500 is connected to the control device 1. The temperature detection module 500 may be arranged in the indoor environment, such as the indoor return air outlet 101.

[0061] Further, see Figure 1 and Figure 3 The air conditioner may further include an air detection module 600, which is used to detect the pollutant concentration (such as carbon dioxide concentration, etc.) of the indoor environment. The air detection module 600 is connected to the control device 1. The air detection module 600 may be arranged in the indoor environment, such as the indoor return air outlet 101.

[0062] In the embodiment of the present invention, refer to Figure 2 The control device 1 of the air conditioner includes: a processor 1001, such as a CPU, a memory 1002, and a timer 1003. Among them, these components are connected and communicated through a communication bus. The memory 1002 can be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. The memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0063] Those skilled in the art will understand that Figure 2 The device structure shown in the figure does not constitute a limitation of the device, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0064] like Figure 2 As shown, the memory 1002 as a computer storage medium may include a control program for the air conditioner.

[0065] exist Figure 2 In the device shown, the processor 1001 can be used to call the air conditioner control program stored in the memory 1002 and execute the relevant steps of the air conditioner control method in the following embodiments.

[0066] The embodiment of the present invention further provides a control method of an air conditioner, which is applied to the above-mentioned air conditioner.

[0067] Reference Figure 4 , an embodiment of a control method of an air conditioner of the present application is proposed. In this embodiment, the control method of the air conditioner includes:

[0068] Step S10, controlling the air conditioner to operate in a dehumidification mode to obtain the outdoor ambient humidity;

[0069] The dehumidification mode is specifically an operation mode aimed at reducing the indoor humidity.

[0070] When the air conditioner is in dehumidification mode, the outdoor humidity can be obtained at set intervals. The outdoor humidity can also be obtained when the air conditioner reaches a preset condition (for example, a fresh air start instruction is received or the indoor environment reaches the fresh air start condition, etc.).

[0071] Step S20, when the outdoor environment humidity is greater than a preset humidity, controlling the fresh air device to operate so that the amount of fresh air delivered to the indoor environment is less than or equal to a preset air volume;

[0072] The preset humidity is specifically the maximum humidity allowed to meet the comfort requirements of the indoor environment. If the outdoor environment humidity is greater than the preset humidity, it indicates that the current large amount of outdoor fresh air introduced will reduce indoor comfort; if the outdoor environment humidity is less than or equal to the preset humidity, it indicates that the current large amount of outdoor fresh air introduced will not reduce indoor comfort. The preset humidity can be determined by monitoring the user status in the indoor environment, or according to the instructions input by the user, or it can be a pre-set fixed parameter.

[0073] The preset air volume is the minimum fresh air volume that can be achieved by the operation of the fresh air device. In other embodiments, the preset air volume can also be other air volumes larger than the minimum fresh air volume, but the preset air volume is less than or equal to 50% of the maximum fresh air volume that can be achieved by the operation of the fresh air device.

[0074] The preset air volume may also be a fixed parameter set in advance, or a parameter determined according to the actual operating state of the air conditioner. For example, the preset air volume here may be determined according to the difference between the outdoor ambient humidity and the preset humidity, or the preset air volume here may be determined according to the dehumidification control parameters corresponding to the dehumidification mode of the air conditioner (compressor frequency, indoor fan speed, deflection angle of the air outlet direction of the indoor air outlet relative to the air outlet direction of the fresh air outlet, etc.), outdoor ambient humidity, indoor ambient humidity, indoor ambient temperature, outdoor ambient temperature and preset humidity, etc.

[0075] Here the fresh air device can be turned off or run at a preset air volume or at a minimum fresh air volume.

[0076] When the fresh air device includes a fresh air fan, the fresh air fan can be controlled to be turned off or to run at a minimum speed; when the fresh air device includes a fresh air damper, the fresh air damper can be controlled to run at a maximum wind blocking angle or to run at a larger preset wind blocking angle. Based on this, the control of the fresh air fan and / or the fresh air damper can achieve that the fresh air volume sent into the indoor environment by the air conditioner is less than or equal to the preset air volume.

[0077] It should be noted that when the fresh air volume is less than or equal to the preset air volume, the air conditioner maintains the dehumidification mode.

[0078] Step S30, obtaining indoor environmental humidity;

[0079] In this embodiment, the indoor environmental humidity is obtained when the fresh air volume is less than or equal to the preset air volume.

[0080] The humidity detected in real time by the first humidity sensor is obtained as the indoor environment humidity here.

[0081] Step S40: controlling the operation of the fresh air device to adjust the fresh air volume according to the indoor environmental humidity.

[0082] Specifically, the operation of the fresh air device can be controlled according to the indoor environmental humidity to increase or decrease the fresh air volume.

[0083] Specifically, the operating parameters of the fresh air device can be determined based on the relationship or size relationship between the indoor ambient humidity and the preset humidity, and the operation of the fresh air device can be controlled according to the determined operating parameters. Different operating parameters here correspond to different fresh air volumes.

[0084] When the fresh air device includes a fresh air fan, the speed control parameters of the fresh air fan (such as the target speed or speed adjustment parameters, etc.) can be determined according to the indoor ambient humidity, and the operation of the fresh air fan can be controlled according to the speed control parameters.

[0085] When the fresh air device includes a fresh air damper, the angle control parameters of the fresh air damper (such as the target wind blocking angle or angle adjustment parameters, etc.) can be determined according to the indoor ambient humidity, and the operation of the fresh air damper can be controlled according to the angle control parameters.

[0086] It should be noted that the indoor humidity comfort level when the fresh air device is operated according to the indoor humidity is greater than the indoor humidity comfort level when the fresh air device is operated according to fixed parameters. When the fresh air device is operated according to the indoor humidity, the air conditioner maintains the dehumidification mode.

[0087] A control method for an air conditioner is proposed in an embodiment of the present invention. During the operation of the air conditioner in a dehumidification mode, when the humidity of the outdoor environment is too high, the method limits the amount of fresh air delivered to the indoor environment to no more than a preset air volume through the operation control of a fresh air device, and further adjusts the fresh air volume based on the operation control of the fresh air device based on the humidity of the indoor environment, to ensure that the amount of fresh air introduced can meet the indoor air freshness requirement while not allowing a large amount of high-humidity air to enter the room and affect the indoor comfort, thereby ensuring the freshness of the indoor environment air in the dehumidification mode while improving the indoor comfort.

[0088] Furthermore, based on the above embodiments, another embodiment of the control method of the air conditioner of the present application is proposed.

[0089] In this embodiment, refer to Figure 5 , the step S40 comprises:

[0090] Step S41, when the indoor environment humidity is lower than the preset humidity, controlling the fresh air device to operate to increase the fresh air volume;

[0091] In this embodiment, the fresh air device includes a fresh air damper arranged in the fresh air duct of the air conditioner and / or a fresh air fan arranged in the fresh air duct, controlling the fresh air fan to increase the rotation speed and / or controlling the fresh air damper to reduce the wind shielding angle.

[0092] Among them, when the wind shielding surface of the fresh air damper is perpendicular to the direction of the fresh air flow, the wind shielding angle is the largest; when the wind shielding surface of the fresh air damper is parallel to the direction of the fresh air flow, the wind shielding angle is the smallest.

[0093] Step S42, when the indoor environment humidity is greater than or equal to the preset humidity, controlling the fresh air device to operate to reduce the fresh air volume.

[0094] In this embodiment, the operation of the fresh air device to reduce the fresh air volume refers to turning off the fresh air device. In other embodiments, the fresh air device may also remain turned on and be adjusted based on the current operating parameters to reduce the fresh air volume.

[0095] In this embodiment, the fresh air device includes a fresh air damper disposed in the fresh air duct of the air conditioner and / or a fresh air fan disposed in the fresh air duct, and the fresh air fan is controlled to reduce the rotation speed and / or the fresh air damper is controlled to increase the wind blocking angle. Specifically, the fresh air fan can be controlled to be turned off and / or the fresh air damper can be controlled to operate at the maximum wind blocking angle.

[0096] In this embodiment, when the fresh air device adjusts the fresh air volume, the operating parameter adjustment values ​​(such as the speed adjustment value of the fresh air fan and / or the angle adjustment value of the fresh air damper, etc.) are all preset fixed amplitudes. For example, the fresh air fan is controlled to increase the speed according to the preset speed adjustment value and / or the fresh air damper is controlled to reduce the wind shielding angle according to the preset angle adjustment value. For example, the speed of the fresh air fan after adjustment = the current speed * 110%; the wind shielding angle of the fresh air damper after adjustment = the current wind shielding angle - 10°.

[0097] In other embodiments, the operating parameter adjustment value when the fresh air device adjusts the fresh air volume may also be a parameter determined according to the actual operating state of the air conditioner. For example, the operating parameter adjustment value may be determined according to the difference between the indoor environment humidity and the preset humidity, or, the operating parameter adjustment value may be determined according to the humidity change value of the indoor environment when the fresh air volume is less than or equal to the preset air volume during the dehumidification mode of the air conditioner, or, the operating parameter adjustment value here may be determined according to the humidity change value of the indoor environment when the fresh air volume is less than or equal to the preset air volume during the dehumidification mode of the air conditioner, the difference between the outdoor environment humidity and the preset humidity, and the difference between the indoor environment humidity and the preset humidity, and so on.

[0098] In this embodiment, if the indoor humidity is less than the preset humidity, it indicates that the indoor humidity has reached a comfortable state. In this case, increasing the fresh air volume is conducive to ensuring that the indoor environment is in a relatively comfortable state while improving the air freshness of the indoor environment. If the indoor humidity is greater than or equal to the preset humidity, it indicates that the indoor humidity has not reached a comfortable state. In this case, reducing the fresh air volume reduces the high humidity outdoor air from entering the room, which causes the indoor humidity environment to further deteriorate, thereby ensuring the freshness of the indoor air while improving the indoor comfort.

[0099] Further, based on any of the above embodiments, another embodiment of the control method of the air conditioner of the present application is proposed. In this embodiment, the preset air volume is the minimum fresh air volume, referring to Figure 6 The step of controlling the operation of the fresh air device so that the amount of fresh air delivered to the indoor environment is less than or equal to the preset air volume includes:

[0100] Step S21, controlling the fresh air device to be closed for a first time period;

[0101] In this embodiment, the first duration is a preset fixed duration, such as 5 minutes. In other embodiments, the first duration may also be a duration determined according to the actual operating state of the air conditioner, for example, the first duration may be determined according to the deviation between the current humidity of the indoor environment and the preset humidity; or the first duration may be determined according to the relative position of the user relative to the fresh air outlet in the indoor environment, and so on.

[0102] Specifically, the fresh air fan is controlled to be turned off and / or the fresh air damper is controlled to close the fresh air duct and maintain the first time period.

[0103] It should be noted that when the fresh air device is turned off, the air conditioner maintains dehumidification mode.

[0104] Step S22, controlling the fresh air device to turn on so that the fresh air volume reaches the minimum fresh air volume.

[0105] When the closing time of the fresh air device reaches the first time, step S22 here can be executed.

[0106] Specifically, the fresh air fan can be controlled to run at the minimum speed, or the fresh air damper can be controlled to run at the maximum wind blocking angle when the fresh air duct is not closed. For example, when the fresh air damper is closed, the wind blocking angle is 90 degrees, and here the fresh air damper can be controlled to run at 80 degrees.

[0107] In this embodiment, the fresh air device remains closed for a period of time in the initial stage, so that the humidity of the indoor environment can be reduced during this period through the dehumidification mode of the air conditioner. After the humidity of the indoor environment is reduced, the fresh air device is turned on again to operate with the minimum fresh air volume to improve the freshness of the indoor air. In this state, the operation of the fresh air device is regulated based on the indoor environment humidity, which is beneficial to avoid the introduction of fresh air into the indoor environment in dehumidification mode, which may cause excessive humidity and affect indoor comfort, thereby ensuring the freshness of the indoor air while improving indoor comfort.

[0108] Furthermore, in this embodiment, after step S21, it also includes: controlling the dehumidification module in the fresh air duct of the air conditioner to turn on, and controlling the fresh air device to turn on so that the amount of fresh air delivered to the indoor environment reaches the minimum air volume.

[0109] When the dehumidification module is turned on, it can be turned on according to the preset fixed operating parameters, or it can be controlled to turn on according to the operating parameters determined according to the actual operating state of the air conditioner. For example, the operating parameters can be determined according to the difference between the outdoor environment humidity and the preset humidity, or the operating parameters can be determined according to the difference between the outdoor environment humidity and the indoor environment humidity, and so on.

[0110] In this embodiment, the dehumidification module is turned on at the same time as the fresh air device is turned on, and the humidity of the fresh air is reduced by the dehumidification module to further avoid the influence of excessive humidity of the fresh air on indoor comfort, thereby ensuring the freshness of the indoor air and further improving the indoor comfort.

[0111] Furthermore, in this embodiment, the dehumidification module includes a semiconductor refrigeration module and a coil connected to the semiconductor refrigeration module for heat exchange, and the step of controlling the dehumidification module to turn on includes: controlling the semiconductor refrigeration module to turn on so that the humidity of the fresh air after heat exchange with the coil is reduced. Specifically, the maximum input current can be input to the semiconductor refrigeration module so that the refrigerant in the coil is quickly cooled, and the fresh air is dehumidified with the maximum dehumidification efficiency.

[0112] In this embodiment, the semiconductor cooling module is turned on to cool the refrigerant in the coil, and the fresh air is dehumidified through heat exchange between the envelope and the refrigerant in the coil, which is beneficial to improve the dehumidification efficiency to further ensure indoor comfort.

[0113] Further, in this embodiment, the process of executing the step of controlling the operation of the fresh air device to adjust the fresh air volume according to the indoor environmental humidity also includes:

[0114] The operating parameters of the semiconductor refrigeration module are adjusted according to the indoor ambient humidity and / or the outdoor ambient humidity.

[0115] In one implementation, when the indoor ambient humidity is lower than a preset humidity, the semiconductor refrigeration module can be controlled to turn off or reduce the input current; when the indoor ambient humidity is greater than or equal to the preset humidity, the semiconductor refrigeration module can be controlled to turn on or increase the input current.

[0116] In another implementation, the operating parameters of the semiconductor refrigeration module can be determined according to the relationship value (such as difference or ratio) between the outdoor ambient humidity and the indoor ambient humidity, and the operation of the semiconductor refrigeration module can be controlled according to the determined operating parameters. Alternatively, a first difference between the indoor ambient humidity and the preset humidity can be determined, a second difference between the outdoor ambient humidity and the preset humidity can be determined, and the operating parameters of the semiconductor refrigeration module can be determined according to the first difference and the second difference.

[0117] In yet another implementation, the operating parameters of the semiconductor refrigeration module may be determined based on a deviation between the outdoor ambient humidity and a preset humidity.

[0118] In this embodiment, the operating parameters of the semiconductor refrigeration module are regulated by the indoor ambient humidity and / or the outdoor ambient humidity to ensure that the dehumidification efficiency of the semiconductor refrigeration module is accurately matched with the indoor comfort requirements during the introduction of fresh air, thereby ensuring the freshness of the indoor air while further improving the indoor comfort.

[0119] Further, based on any of the above embodiments, another embodiment of the control method of the air conditioner of the present application is proposed. In this embodiment, after step S40, it also includes: after a second time interval, returning to the step of obtaining the indoor environment humidity, until the pollutant concentration of the indoor environment is less than a preset concentration, and turning off the fresh air device.

[0120] Specifically, after step S40, the pollutant concentration (such as CO2 concentration, etc.) of the indoor environment can be detected. When the pollutant concentration is less than the preset concentration, the fresh air device is controlled to be turned off; when the pollutant concentration is greater than or equal to the preset concentration, the step of obtaining the indoor environment humidity is returned to after a second time interval.

[0121] The second duration may be a preset fixed duration, such as 5 minutes, etc. The second duration may also be a duration determined according to the actual operating state of the air conditioner. For example, the second duration here may be determined according to the difference between the indoor ambient humidity and the preset humidity, and so on.

[0122] In this embodiment, the operation of the fresh air device is continuously regulated based on the indoor environmental humidity to ensure that the operation of the fresh air device can be dynamically adjusted to adapt to the actual humidity state of the indoor environment, thereby further improving the comfort of the indoor humidity environment while ensuring indoor comfort by introducing fresh air through the fresh air device.

[0123] Further, based on any of the above embodiments, another optional embodiment of the control method of the air conditioner of the present application is proposed. In this embodiment, after step S10, it also includes:

[0124] Step S50, when the outdoor environment humidity is less than or equal to the preset humidity, control the fresh air device to turn on.

[0125] Here, the fresh air volume when the fresh air device is turned on can be greater than the above-mentioned preset air volume.

[0126] Specifically, the fresh air fan may be controlled to open and / or the wind blocking angle of the fresh air damper may be controlled to be 0.

[0127] In this embodiment, when the outdoor environment humidity is less than or equal to the preset humidity, it indicates that the introduction of outdoor fresh air will not reduce the comfort of the indoor environment, but will also help improve the indoor humidity comfort. At this time, directly turning on the fresh air device is conducive to ensuring indoor comfort while improving the freshness of the indoor environment.

[0128] Furthermore, based on any of the above embodiments, another optional embodiment of the control method of the air conditioner of the present application is proposed. The control method of the air conditioner also includes: obtaining the outdoor ambient temperature during the process of turning on the fresh air device; when the outdoor ambient temperature is less than the preset temperature, controlling the fresh air heating module to turn on.

[0129] In this embodiment, the preset temperature is a preset fixed temperature. In other embodiments, the preset temperature can also be determined according to preset humidity and / or indoor ambient temperature.

[0130] The heating power when the fresh air heating module is turned on can be a pre-set fixed power, or it can be a power determined according to the actual operating status of the air conditioner. For example, the heating power of the fresh air heating module can be determined according to the temperature difference between the outdoor ambient temperature and the preset temperature, or it can be determined according to the temperature difference between the outdoor ambient temperature and the preset temperature and the temperature difference between the outdoor ambient temperature and the indoor ambient temperature.

[0131] In this embodiment, when the fresh air temperature is too low, the fresh air heating module is turned on, which helps to prevent the fresh air temperature from being too low and affecting the comfort of the indoor environment, thereby further improving the indoor comfort and air freshness of the air conditioner in the dehumidification mode.

[0132] Further, based on any of the above embodiments, another optional embodiment of the control method of the air conditioner of the present application is proposed. The control method of the air conditioner also includes: controlling the air conditioner to operate in a dehumidification mode to obtain the pollutant concentration of the indoor environment; when the pollutant concentration is greater than a preset concentration, executing the step of obtaining the outdoor environment humidity; when the pollutant concentration is less than or equal to the preset concentration, controlling the fresh air device to be turned off.

[0133] In this embodiment, the pollutant concentration is the carbon dioxide concentration. In other embodiments, the pollutant concentration may also be the concentration of other air pollutants such as formaldehyde concentration.

[0134] In this embodiment, when the air conditioner is operating in dehumidification mode, the indoor pollutant concentration is greater than the preset concentration, indicating that the indoor air freshness is poor and will affect the health of the user. At this time, the operation of the fresh air device is regulated based on the method mentioned in the above embodiment in combination with the outdoor environment humidity and the indoor environment humidity, which is beneficial to ensure the freshness of the air to meet the health needs of the user while improving the comfort of the indoor humidity environment; in addition, when the indoor pollutant concentration is less than or equal to the preset concentration, it indicates that the indoor air freshness is good and there is no need to introduce outdoor fresh air. At this time, the fresh air device can be turned off to reduce the impact on the indoor humidity environment, thereby ensuring the freshness of the indoor air while improving the indoor comfort.

[0135] In addition, an embodiment of the present invention further proposes a storage medium, on which a control program for an air conditioner is stored. When the control program for the air conditioner is executed by a processor, the relevant steps of any embodiment of the control method for the air conditioner are implemented.

[0136] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or system. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or system including the element.
