[0059] The present application first provides a control method of a plant air-conditioning room. Figure 1 and Figure 2 are respectively schematic structural diagrams of a plant air-conditioning room in different states according to an embodiment of the present application, referring to Figure 1 and Figure 2 , the air-conditioning room 1 comprises a shell 10, an inside of the shell 10 defines a containing space 11 for containing plants, the containing space 11 is provided with an air-conditioning room indoor unit 20 for adjusting air environment in the containing space 11.

[0060] The control method of the present application is designed based on the air-conditioning room 1 with the above structure.

[0061] The control method of the plant air-conditioning room of the present application comprises:

[0062] obtaining a first temperature in the containing space 11 and a second temperature in a space where the air-conditioning room 1 is located;

[0063] adjust the operation mode of the air conditioner indoor unit 20 according to the first temperature and the second temperature when the first temperature is out of the preset temperature range; wherein

[0064] The operation mode of the air conditioner indoor unit 20 at least includes a heating mode, a cooling mode and a natural air supply mode; in the heating mode and the cooling mode, the air conditioner indoor unit 20 promotes the air flow inside the accommodation space 11 to flow into the accommodation space 11 after heat exchange; in the natural air supply mode, the air conditioner indoor unit 20 promotes the air flow in the space where the air conditioner room 1 is located to directly flow into the accommodation space 11.

[0065] The control method of the air conditioner room of the present application obtains the first temperature in the accommodation space 11 and the second temperature in the space where the air conditioner room 1 is located, and when the first temperature in the accommodation space 11 is out of the preset temperature range, it indicates that the temperature in the accommodation space 11 is not suitable for the growth of plants, at this time, the operation mode of the air conditioner indoor unit 20 can be adjusted according to the size of the first temperature and the second temperature and the size relationship between them, so that the temperature of the accommodation space 11 is more suitable for the growth of plants, which reduces the user's effort, makes up for the lack of user planting experience, and improves the user's confidence and pleasure in planting plants.

[0066] More importantly, the operation mode of the air conditioner indoor unit 20 not only includes the traditional cooling mode and heating mode, but also includes the natural air supply mode. In the natural air supply mode, the air conditioner indoor unit 20 promotes the air flow in the space where the air conditioner room 1 is located to directly flow into the accommodation space 11 without heat exchange, which ingeniously utilizes the air environment outside the air conditioner room 1, greatly saves the energy consumption of the air conditioner room 1, and reduces the cost of the user planting plants.

[0067] Specifically, Figure 3 is a schematic flow chart of the control method of the air conditioner room for plants according to an embodiment of the present application. Referring to Figure 3 In a specific embodiment, the control method of the present application comprises:

[0068] Step S10, obtaining the first temperature in the accommodation space 11 and the second temperature in the space where the air conditioner room 1 is located;

[0069] Step S20, judging whether the first temperature is within the preset temperature range; if yes, returning to step S10; if no, turning to step S30;

[0070] Step S30, adjusting the operation mode of the air conditioner indoor unit 20 according to the first temperature and the second temperature.

[0071] In some embodiments, the step S30 of adjusting the operation mode of the air conditioner indoor unit 20 according to the first temperature and the second temperature can specifically include:

[0072] If the first temperature is greater than the maximum endpoint value of the preset temperature range, and the temperature difference between the first temperature and the second temperature is greater than or equal to the first preset temperature value, the air conditioner indoor unit 20 is controlled to operate in the natural air supply mode;

[0073] If the first temperature is less than the minimum endpoint value of the preset temperature range, and the temperature difference between the second temperature and the first temperature is greater than or equal to the first preset temperature value, the air conditioner indoor unit 20 is controlled to operate in the natural air supply mode;

[0074] If the first temperature is greater than the maximum endpoint value of the preset temperature range, and the temperature difference between the first temperature and the second temperature is less than the first preset temperature value, the air conditioner indoor unit 20 is controlled to operate in the cooling mode;

[0075] If the first temperature is less than the minimum endpoint value of the preset temperature range, and the temperature difference between the second temperature and the first temperature is less than the first preset temperature value, the air conditioner indoor unit 20 is controlled to operate in the heating mode.

[0076] Specifically, when the first temperature is greater than the maximum endpoint value of the preset temperature range, it indicates that the temperature in the air conditioner room 1 is relatively high, which is not suitable for the growth of the plants in the accommodation space 11. At this time, if the first temperature is higher than the second temperature, and the temperature difference between the first temperature and the second temperature is relatively large, it indicates that the temperature in the environment space where the air conditioner room 1 is located is relatively low, and the air in the environment space can be fully utilized to appropriately reduce the temperature in the accommodation space 11, so as to make it conducive to the growth of the plants. Therefore, at this time, the air conditioner indoor unit 20 operates in the natural air supply mode, and only the airflow driving device of the air conditioner indoor unit 20 is used to send the external air into the accommodation space 11, which can effectively improve the temperature in the accommodation space 11, and the air does not need to be heat exchanged, thereby effectively reducing the energy consumption of the air conditioner indoor unit 20. On the contrary, if the temperature difference between the first temperature and the second temperature is relatively small, or even the first temperature is lower than the second temperature, and it indicates that the temperature in the environment space where the air conditioner room 1 is located is not much different from the temperature in the air conditioner room 1, or even higher than the temperature in the air conditioner room 1, the air in the environment space where the air conditioner room 1 is located cannot effectively improve the temperature in the accommodation space 11, and at this time, the air conditioner indoor unit 20 is controlled to operate in the cooling mode, which can effectively reduce the temperature in the accommodation space 11, so as to make it more conducive to the growth of the plants.

[0077] When the first temperature is less than the minimum end point value of the preset temperature range, it indicates that the temperature in the air-conditioned room 1 is low, which is not suitable for the growth of the plants in the accommodating space 11. At this time, if the first temperature is lower than the second temperature and the temperature difference between the second temperature and the first temperature is large, it indicates that the temperature in the environment space where the air-conditioned room 1 is located is relatively high, and the air in the environment space can be fully utilized to appropriately increase the temperature in the accommodating space 11, so as to make it beneficial for the growth of the plants. Therefore, at this time, the air-conditioned room indoor unit 20 is controlled to operate in the natural air supply mode, and only the airflow driving device of the air-conditioned room indoor unit 20 is used to send the external air into the accommodating space 11, so as to effectively improve the temperature in the accommodating space 11, and the air does not need to be heat exchanged, thereby effectively reducing the energy consumption of the air-conditioned room indoor unit 20. Conversely, if the temperature difference between the second temperature and the first temperature is small, or even the first temperature is higher than the second temperature, and it indicates that the temperature in the environment space where the air-conditioned room 1 is located is not much different from the temperature in the air-conditioned room 1, or even lower than the temperature in the air-conditioned room 1, the air in the environment space where the air-conditioned room 1 is located cannot effectively improve the temperature in the accommodating space 11, and at this time, the air-conditioned room indoor unit 20 is controlled to operate in the heating mode, so as to effectively increase the temperature in the accommodating space 11, and make it more beneficial for the growth of the plants.

[0078] Specifically, Figure 4 is a schematic flow chart of a control method of the air-conditioned room for plants according to another embodiment of the present application. Referring to Figure 4 In a specific embodiment, the control method of the present application comprises:

[0079] In step S10, the first temperature in the accommodating space 11 and the second temperature in the space where the air-conditioned room 1 is located are obtained.

[0080] In step S20, it is judged whether the first temperature is in the preset temperature range. If yes, the process returns to step S10; if no, the process proceeds to step S30.

[0081] In step S301, it is judged whether the first temperature is greater than the maximum end point value of the preset temperature range. If yes, the process proceeds to step S311; if no, the process proceeds to step S321.

[0082] In step S311, the temperature difference between the first temperature and the second temperature is calculated.

[0083] In step S312, it is judged whether the temperature difference between the first temperature and the second temperature is greater than or equal to the first preset temperature value. If yes, the process proceeds to step S331; if no, the process proceeds to step S332.

[0084] In step S331, the air-conditioned room indoor unit is controlled to operate in the natural air supply mode.

[0085] In step S332, the air-conditioned room indoor unit is controlled to operate in the cooling mode.

[0086] Step S321, calculating the temperature difference between the second temperature and the first temperature;

[0087] Step S322, judging whether the temperature difference between the second temperature and the first temperature is greater than or equal to the first preset temperature value; if yes, turning to step S331; if no, turning to step S333;

[0088] Step S333, controlling the air conditioner indoor unit to operate in the heating mode.

[0089] It can be understood that the execution of step S301 is premised on that the first temperature is out of the preset temperature range. If the judgment result of step S301 is no, i.e. the first temperature is less than the maximum endpoint value of the preset temperature range, then at this time, the first temperature must be less than the minimum endpoint value of the preset temperature range, and it is not necessary to compare the first temperature with the minimum endpoint value of the preset temperature range again.

[0090] It should be noted that step S301 can also compare whether the first temperature is greater than the minimum endpoint value of the preset temperature range, and if yes, the first temperature must be greater than the maximum endpoint value of the preset temperature range, and other control logics remain unchanged.

[0091] Figure 5 is a schematic structural sectional view of a plant air-conditioning room according to an embodiment of the present application, Figure 6 is Figure 5 is a schematic enlarged view of part A in Figure 7 is a schematic partial structural enlarged view of the air conditioner indoor unit in another state, Figure 8 is a schematic structural exploded view of an air conditioner indoor unit according to an embodiment of the present application. In some embodiments, the air conditioner room 1 further comprises a shell 10, a containing space 11 is defined in the shell 10, and a ventilation opening 12 is formed on the shell 10. The ventilation opening 12 communicates the containing space 11 in the shell 10 and the environment space where the shell 10 is located.

[0092] Further, the air conditioner indoor unit 20 comprises a casing 21, an air path adjusting mechanism 22 and an airflow driving device 24. The casing 21 is provided with a first air inlet 211 which is in communication with the accommodation space 11 and isolated from the air vent 12, a second air inlet 212 which is in communication with the air vent 12 and isolated from the accommodation space 11, and at least one air outlet which is in communication with the accommodation space 11. That is, the first air inlet 211 is only in communication with the accommodation space 11 and not in communication with the air vent 12, and the first air inlet 211 only allows air in the accommodation space 11 to pass into the casing 21. The second air inlet 212 is only in communication with the air vent 12 and not in communication with the accommodation space 11, and the second air inlet 212 only allows air in the indoor space where the shell 10 is located (i.e. the indoor space where the air conditioner room 1 is located) to pass into the casing 21. The number of air outlets can be one or more, and each air outlet is in communication with the accommodation space 11 to discharge air in the casing 21 into the accommodation space 11.

[0093] The airflow driving device 24 is arranged in the casing 21 and is used to drive airflow to flow in a controlled manner.

[0094] The air path adjusting mechanism 22 is movably arranged in the casing 21 and has a first state (as shown in the state) in which the first air inlet 211 is opened and the second air inlet 212 is blocked, and a second state (as shown in the state) in which the second air inlet 212 is opened and the first air inlet 211 is blocked, so as to adjust the air path of the air conditioner room 1 by switching the state of the air path adjusting mechanism 22. Figure 7 Figure 6 The air path adjusting mechanism 22 is movably arranged in the casing 21 and has a first state (as shown in the state) in which the first air inlet 211 is opened and the second air inlet 212 is blocked, and a second state (as shown in the state) in which the second air inlet 212 is opened and the first air inlet 211 is blocked, so as to adjust the air path of the air conditioner room 1 by switching the state of the air path adjusting mechanism 22.

[0095] The casing 21 of the air conditioner indoor unit 20 is provided with two air inlets, wherein the first air inlet 211 is in communication with the accommodation space 11 and isolated from the air vent 12 on the shell 10, and the second air inlet 212 is isolated from the accommodation space 11 and in communication with the air vent 12 on the shell 10. That is, the air conditioner indoor unit 20 not only allows air in the accommodation space 11 where it is located to enter it through the first air inlet 211, but also allows air outside the air conditioner room 1 to enter it through the second air inlet 212. Furthermore, the casing 21 is also provided with the air path adjusting mechanism 22, which can adjust the opening and closing of the first air inlet 211 and the second air inlet 212 by switching the state thereof.

[0096] Based on the air conditioner room 1 having the above structure, the step of controlling the air conditioner indoor unit 20 to operate in the natural air supply mode can specifically comprise:

[0097] Only the airflow driving device 24 is started, and the air path adjusting mechanism 22 is adjusted to the second state thereof. That is, in the natural air supply mode, the compressor of the air conditioner indoor unit 20 is not started, and the heat exchanger of the air conditioner indoor unit 20 has no refrigerant flowing therethrough, and thus cannot exchange heat with the airflow flowing therethrough. ​

[0098] Based on the air conditioning chamber 1 with the above structure, the step of controlling the air conditioning indoor unit 20 to operate in the heating mode or in the cooling mode can specifically include:

[0099] The air flow driving device 24 and the compressor of the air conditioning indoor unit 20 are started, and the air path adjusting mechanism 22 is adjusted to the first state. That is, in the heating mode and the cooling mode, the air flow driving device 24 and the compressor are started, so that the refrigerant flows through the heat exchanger of the air conditioning indoor unit 20, thereby exchanging heat with the air flow flowing through the heat exchanger. It can be understood that the flow direction of the refrigerant is different in the heating mode and the cooling mode, and since this technology is well known in the art, it will not be described here.

[0100] In summary, in this embodiment, the switching of the operating mode of the air conditioning indoor unit 120 is achieved by switching the state of the air path adjusting mechanism 22. The present application cleverly achieves the switching of the operating mode of the air conditioning indoor unit 120 by opening the special first air inlet 211 and the second air inlet 212 on the casing 21 and setting the air path adjusting mechanism 22, and the structure is very simple, and the state switching process of the air path adjusting mechanism 22 is simple and easy to control.

[0101] In some embodiments, the air flow driving device 24 is a fan. Specifically, the air flow driving device 24 can be a cross-flow fan, or an axial-flow fan or a centrifugal fan.

[0102] Further, in the natural air supply mode, the speed of the fan is inversely related to the absolute value of the temperature difference between the first temperature and the second temperature. That is, the greater the absolute value of the temperature difference between the first temperature and the second temperature, the greater the temperature compensation amount that a unit volume of air from outside the air conditioning chamber 1 can provide, and the smaller the speed of the fan; on the contrary, the greater the speed of the fan.

[0103] Further, in the heating mode, the speed of the fan is inversely related to the first temperature. That is, the higher the first temperature, the relatively less heat required in the accommodation space 11, and the smaller the speed of the fan; on the contrary, the greater the speed of the fan.

[0104] Further, in the cooling mode, the speed of the fan is positively related to the first temperature. That is, the higher the first temperature, the relatively more heat required in the accommodation space 11, and the greater the speed of the fan; on the contrary, the smaller the speed of the fan.

[0105] In some embodiments, the air conditioning indoor unit 20 further comprises a heat exchanger 23 movably arranged in the casing 21.

[0106] In these embodiments, when the air conditioning indoor unit 20 operates in the natural air supply mode, the control method of the present application further comprises:

[0107] Adjust the heat exchanger 23 to the air flow path in which the second air inlet 212 is located.

[0108] When the air conditioner indoor unit 20 is operated in the cooling mode or the heating mode, the control method of the present application further comprises:

[0109] Adjust the heat exchanger 23 to the air flow path in which the first air inlet 211 is located.

[0110] Specifically, Figure 9 is a schematic flow chart of the control method of the plant air conditioner room according to still another embodiment of the present application. Referring to Figure 9 In one specific embodiment, the control method of the present application comprises:

[0111] Step S10, acquire the first temperature in the accommodation space 11 and the second temperature in the space where the air conditioner room 1 is located;

[0112] Step S20, determine whether the first temperature is within the preset temperature range; if yes, return to step S10; if no, go to step S30;

[0113] Step S301, determine whether the first temperature is greater than the maximum endpoint value of the preset temperature range; if yes, go to step S311; if no, go to step S321;

[0114] Step S311, calculate the temperature difference between the first temperature and the second temperature;

[0115] Step S312, determine whether the temperature difference between the first temperature and the second temperature is greater than or equal to the first preset temperature value; if yes, go to step S331'; if no, go to step S332';

[0116] Step S331', control the air conditioner indoor unit 20 to operate in the natural air supply mode, and adjust the heat exchanger 23 to the air flow path in which the second air inlet 212 is located;

[0117] Step S332', control the air conditioner indoor unit 20 to operate in the cooling mode, and adjust the heat exchanger 23 to the air flow path in which the first air inlet 211 is located;

[0118] Step S321, calculate the temperature difference between the second temperature and the first temperature;

[0119] Step S322, determine whether the temperature difference between the second temperature and the first temperature is greater than or equal to the first preset temperature value; if yes, go to step S331'; if no, go to step S333';

[0120] Step S333', control the air conditioner indoor unit 20 to operate in the heating mode, and adjust the heat exchanger 23 to the air flow path in which the first air inlet 211 is located.

[0121] When the air conditioner indoor unit 20 is in the heating mode or the cooling mode, the air path adjusting mechanism 22 is in its first state, the first air inlet 211 is open, and the second air inlet 212 is blocked. At this time, the heat exchanger 23 is moved to the air flow path where the first air inlet 211 is located, so as to be in full contact with the air flow entering the casing 21 from the first air inlet 211, thereby making the air flow fully exchange heat with the heat exchanger 23, and improving the air conditioning effect of the air conditioner room 1 when the air path adjusting mechanism 22 is in its first state.

[0122] When the air conditioner indoor unit 20 is in the natural air supply mode, the air path adjusting mechanism 22 is in its second state, the first air inlet 211 is blocked, and the second air inlet 212 is open. At this time, the heat exchanger 23 is moved to the air flow path where the second air inlet 212 is located, so as to be in full contact with the air flow entering the casing 21 from the second air inlet 212. At this time, although the compressor of the air conditioner indoor unit 20 is not started, the heat exchanger 23 may still have a certain amount of residual heat or residual cold. Therefore, moving the heat exchanger 23 to the air flow path where the second air inlet 212 is located can fully utilize the residual heat or residual cold. In addition, the heat exchanger 23 can also filter and purify the air flow entering the casing 21 from the second air inlet 212 to a certain extent, so as to improve the cleanliness of the air flow flowing into the accommodation space 11.

[0123] Preferably, the air path adjusting mechanism 22 and the heat exchanger 23 can be driven by the same driving device 25, so that they are synchronously rotated around the same rotating shaft.

[0124] In some embodiments, the at least one air outlet includes a first air outlet 213 arranged opposite to the first air inlet 211, and a second air outlet 214 arranged opposite to the second air inlet 212.

[0125] Further, the air path adjusting mechanism 22 is configured to open the first air outlet 213 and block the second air outlet 214 in the first state, and open the second air outlet 214 and block the first air outlet 213 in the second state. That is, when the air path adjusting mechanism 22 is in the first state, the first air inlet 211 and the first air outlet 213 are opened, and the second air inlet 212 and the second air outlet 214 are blocked, so that the air in the accommodation space 11 enters the cabinet 21 through the first air inlet 211 and flows out of the cabinet 21 from the first air outlet 213. When the air path adjusting mechanism 22 is in the second state, the first air inlet 211 and the first air outlet 213 are blocked, and the second air inlet 212 and the second air outlet 214 are opened, so that the air in the indoor space where the air conditioner room 1 is located enters the cabinet 21 through the second air inlet 212 and flows out of the cabinet 21 from the second air outlet 214. Since the first air inlet 211 and the first air outlet 213 are oppositely arranged, and the second air inlet 212 and the second air outlet 214 are oppositely arranged, the air flow in the cabinet 21 can be straightly flowed no matter the air path adjusting mechanism 22 is in the first state or the second state, so that the change of the flow direction is reduced, the air flow resistance is reduced, and the air flow speed is improved.

[0126] In some embodiments, the cabinet 21 is a cylinder, and the first air inlet 211, the second air inlet 212, the first air outlet 213 and the second air outlet 214 are all arranged on the side wall of the cylinder and are spaced apart along the circumference of the cylinder. That is, the first air inlet 211, the second air inlet 212, the first air outlet 213 and the second air outlet 214 are all arc-shaped air inlets with the center of the cylinder as the center.

[0127] Further, the air path adjusting mechanism 22 includes two arc-shaped baffles 221 which are matched with the shape of the side wall of the cylinder, and the two arc-shaped baffles 221 block the second air inlet 212 and the second air outlet 214 respectively when the air path adjusting mechanism 22 is in the first state, and block the first air inlet 211 and the first air outlet 213 respectively when the air path adjusting mechanism 22 is in the second state. In this way, the air in the flow path between the first air inlet 211 and the first air outlet 213 can be effectively prevented from flowing out of the cabinet 21 through the second air inlet 212 and the second air outlet 214, and the air in the flow path between the second air inlet 212 and the second air outlet 214 can be effectively prevented from flowing out of the cabinet 21 through the first air inlet 211 and the first air outlet 213, so that the air supply amount in various situations is ensured, and the air improvement effect in the accommodation space 11 is improved.

[0128] Since the air path adjusting mechanism 22 and the heat exchanger 23 are rotatable, the rotation tracks of the air path adjusting mechanism 22 and the heat exchanger 23 are circular or arc-shaped. Therefore, the application sets the casing 21 as a cylinder, and sets the first air inlet 211 and the second air inlet 212 and the air outlet on the sidewall of the cylinder, so that the air path adjusting mechanism 22 can always keep a good shielding relationship with the first air inlet 211 or the second air inlet 212 after rotation. Moreover, under the premise of ensuring smooth rotation of the air path adjusting mechanism 22 and the heat exchanger 23, the cylindrical casing 21 has the highest space utilization and occupies the smallest space in the accommodation space, which is a very ingenious design.

[0129] In some embodiments, the shell 10 includes a main body 10a having an entrance 10a1 and a door body 10b for closing and / or opening the entrance 10a1. In these embodiments, when the air conditioner indoor unit 20 operates in the natural air supply mode, the control method of the application further includes opening the door body 10b. When the air conditioner indoor unit 20 operates in the cooling mode or the heating mode, the control method of the application further includes closing the door body 10b.

[0130] When the air conditioner indoor unit 20 operates in the natural air supply mode, opening the door body 10b can promote the air flow between the inside and outside of the air conditioner room 1, so as to more quickly improve the temperature in the accommodation space 11 by using the air outside the air conditioner room 1. When the air conditioner indoor unit 20 operates in the cooling mode or the heating mode, closing the door body 10b can isolate the environment outside the air conditioner room 1 that is not suitable for plant growth from the air conditioner room 1, and improve the air conditioning speed in the accommodation space 11.

[0131] In some embodiments, the second air inlet 212 is arranged opposite and spaced apart from the ventilation port 12 to form a buffer space 13 between the second air inlet 212 and the ventilation port 12. The other sides of the buffer space 13 except the side where the second air inlet 212 and the ventilation port 12 are located are isolated from the accommodation space 11 by a sealing plate 14.

[0132] The sealing plate 14 effectively separates the ventilation port 12 from the other areas of the accommodation space 11 except the buffer space 13 and the second air inlet 212, so that the external air entering from the ventilation port 12 can only flow into the buffer space 13 and then flow into the second air inlet 212.

[0133] The buffer space 13 can provide flow buffering for the air flowing into the air conditioning chamber 1 from the air vent 12, reduce the resistance encountered by the air flowing into the air conditioning chamber 1 from the air vent 12, and thus increase the air intake of the air vent 12. In addition, the buffer space 13 can provide distance buffering, increase the distance between the second air inlet 212 and the air vent 12, and avoid the problem that the heat or cold in the air conditioning indoor unit 20 is easily lost to the outside of the air conditioning chamber 1 due to the short distance between the second air inlet 212 and the air vent 12. In addition, the buffer space 13 can provide visual buffering, avoid the user directly viewing the air conditioning indoor unit 20 through the air vent 12, and improve the appearance of the air conditioning chamber 1.

[0134] The application also provides an air conditioning chamber for plants. Figure 10 is a schematic structural block diagram of an air conditioning chamber according to an embodiment of the application. The air conditioning chamber 1 includes a shell 10, an air conditioning indoor unit 20, a first temperature detection device 30, a second temperature detection device 40, and a control device 90.

[0135] The shell 10 defines an accommodation space 11 inside for accommodating plants. The air conditioning indoor unit 20 is arranged in the accommodation space 11. The first temperature detection device 30 is configured to obtain a first temperature in the accommodation space 11, and the second temperature detection device 40 is configured to obtain a second temperature in a space where the air conditioning chamber 1 is located. The control device 90 includes a processor 91 and a memory 92, the memory 92 stores a machine executable program 93, and the machine executable program 93 is executed by the processor 91 to implement the control method described in any of the above embodiments.

[0136] Specifically, the processor 91 can be a central processing unit (CPU) or a digital processing unit, etc. The processor 91 transmits and receives data through a communication interface. The memory 92 is configured to store programs executed by the processor 91. The memory 92 is any medium capable of carrying or storing desired program codes in the form of instructions or data structures and capable of being accessed by a computer, and can also be a combination of multiple memories. The above machine executable program 93 can be downloaded from a computer readable storage medium to a corresponding computing / processing device or downloaded to a computer or an external storage device via a network (such as the Internet, a local area network, a wide area network, and / or a wireless network).
