Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration, and particularly to a refrigerator. Background Art

[0002] As a common household appliance, a refrigerator can store items at a low temperature. With the improvement of people's living standards, higher requirements are put forward for the freshness preservation effect of the refrigerator. Theoretical research finds that the magnetic field has a great influence on the low-temperature storage of food materials. Because the magnetic field restricts the free path of water molecules to a certain extent, inhibiting the growth of crystal nuclei, so that the food materials are less likely to freeze at a low temperature, and thus refrigeration can be achieved at a certain sub-zero low temperature, or the ice crystals generated during the freezing of the food materials can be reduced to reduce the damage to the food material cells. Therefore, applying a magnetic field to the food materials can play a good auxiliary role in the low-temperature storage of the food materials and improve the freshness preservation effect of the food materials. Therefore, the refrigerator field actively explores introducing a magnetic field into freshness preservation storage to improve the freshness preservation effect of the refrigerator. Summary of the Invention

[0003] An object of the present invention is to provide a refrigerator that can apply a magnetic field to food materials to improve the freshness preservation effect.

[0004] A further object of the present invention is to improve the refrigeration efficiency.

[0005] Another further object of the present invention is to make the refrigerant flow more easily.

[0006] In particular, the present invention provides a refrigerator, wherein the refrigerator is formed with a food material placement area, and the refrigerator includes:

[0007] Two magnetic field homogenizing plates, which are respectively arranged on opposite sides of the food material placement area; and

[0008] At least one magnetic field generating member, which is used to generate a magnetic field in the food material placement area. One magnetic field generating member is correspondingly arranged with one magnetic field homogenizing plate, and the magnetic field generating member is arranged on the side of the corresponding magnetic field homogenizing plate facing the food material placement area;

[0009] Wherein, the refrigerator includes at least one freshness preservation evaporator, the freshness preservation evaporator is used to refrigerate the food material placement area, and the freshness preservation evaporator includes a plate-shaped part, and the plate-shaped part constitutes one of the magnetic field homogenizing plates.

[0010] Optionally, the refrigerator includes two magnetic conduction connecting members, the two ends of the magnetic conduction connecting members are respectively connected to the two magnetic field homogenizing plates, and the two magnetic conduction connecting members are respectively located on opposite sides of the food material placement area, so that the two magnetic field homogenizing plates and the two magnetic conduction connecting members jointly form a ring-shaped magnetic conduction path.

[0011] Optionally, a refrigerant pipeline is provided in the plate-shaped part. The plate-shaped part is provided with an inlet and an outlet communicating with the refrigerant pipeline, so that the refrigerant enters the refrigerant pipeline through the inlet and flows out of the refrigerant pipeline through the outlet.

[0012] Optionally, the two magnetic field homogenizing plates are respectively arranged on the top side and the bottom side of the food placement area, so that the plate-shaped parts of the preservation evaporators constituting the magnetic field homogenizing plates are arranged horizontally.

[0013] Optionally, the preservation evaporator includes a heat dissipation part connected to the plate-shaped part, and the heat dissipation part is provided with a plurality of fins.

[0014] Optionally, the refrigerator includes two magnetic field generating members respectively arranged corresponding to the two magnetic field homogenizing plates, and the magnetic field generating members are arranged on the side of the corresponding magnetic field homogenizing plate facing the food placement area.

[0015] Optionally, the refrigerator includes two preservation evaporators, and the plate-shaped parts of the two preservation evaporators respectively constitute the two magnetic field homogenizing plates.

[0016] Optionally, the magnetic field generating member is an electromagnetic coil, or the magnetic field generating member is a permanent magnet sheet, or the magnetic field generating member is a component composed of an electromagnetic coil and a permanent magnet sheet.

[0017] Optionally, the plate-shaped part of the preservation evaporator is made of iron or steel material.

[0036] The refrigerator of the present application has a food placement area. The refrigerator includes two uniform magnetic plates, which are respectively arranged on opposite sides of the food placement area; at least one magnetic field generating member for generating a magnetic field in the food placement area, one magnetic field generating member is correspondingly arranged with one uniform magnetic plate, and the magnetic field generating member is arranged on the side of the corresponding uniform magnetic plate facing the food placement area; and two magnetic conduction connectors, the two ends of the magnetic conduction connectors are respectively connected to the two uniform magnetic plates, and the two magnetic conduction connectors are respectively located on opposite sides of the food placement area, so that the two uniform magnetic plates and the two magnetic conduction connectors jointly form a ring-shaped magnetic conduction path; wherein, the refrigerator includes at least one fresh-keeping evaporator for refrigerating the food placement area, and the fresh-keeping evaporator includes a plate-shaped part, and the plate-shaped part constitutes one uniform magnetic plate.

[0037] As Figures 1 to 4 shown, in one embodiment, the refrigerator includes a box body 100, a fresh-keeping evaporator 200, a magnetic field homogenizing plate 300, two magnetic field generating members 400, and two magnetic conduction connecting members 500. The box body 100 is formed with a magnetic field fresh-keeping compartment 101. A part of the space in the magnetic field fresh-keeping compartment 101 serves as a food placement area 102 for placing food. Specifically, a drawer may be provided in the magnetic field fresh-keeping compartment 101, and the internal space of the drawer serves as the food placement area 102, or a partition may be provided in the magnetic field fresh-keeping compartment 101, and the partition divides out the food placement area.

[0038] Referring Figures 1 to 4 to the figure shown, the fresh-keeping evaporator 200 and the magnetic field homogenizing plate 300 are arranged in the magnetic field fresh-keeping compartment 101, and the fresh-keeping evaporator 200 and the magnetic field homogenizing plate 300 are respectively arranged on opposite sides of the food placement area 102. The fresh-keeping evaporator 200 is used to release cold to the magnetic field fresh-keeping compartment 101, thereby refrigerating the magnetic field fresh-keeping compartment 101, or rather, the food placement area 102.

[0039] Referring Figure 3 and Figure 4 to the figure shown, further specifically, the fresh-keeping evaporator 200 has a plate-shaped part 210. A refrigerant pipeline 211 is arranged inside the plate-shaped part 210. The plate-shaped part 210 is provided with an inlet 212 and an outlet 213 that communicate with the refrigerant pipeline 211, so that the refrigerant enters the refrigerant pipeline 211 through the inlet 212 and flows out of the refrigerant pipeline 211 through the outlet 213.

[0040] Specifically, a bent refrigerant pipeline 211 is arranged inside the plate-shaped part 210. The inlet 212 of the refrigerant pipeline 211 is connected to an input pipe 230, and the outlet of the refrigerant pipeline 211 is connected to an output pipe 240. The refrigerant enters the refrigerant pipeline 211 along the input pipe 230, then flows inside the refrigerant pipeline 211, and releases cold during the flowing process, so that the cold enters the magnetic field fresh-keeping compartment 101, thereby refrigerating the food placement area 102. Finally, the refrigerant flows out of the refrigerant pipeline 211 from the output pipe 240.

[0041] Referring Figures 1 to 3 to the figure shown, the plate-shaped part 210 and the magnetic field homogenizing plate 300 are arranged opposite to each other. The two ends of the magnetic conduction connecting member 500 are respectively connected to the plate-shaped part 210 and the magnetic field homogenizing plate 300, and the two magnetic conduction connecting members 500 are respectively located on opposite sides of the food placement area 102.

[0042] Specifically, the fresh-keeping evaporator 200 and the magnetic field homogenizing plate 300 are respectively arranged on the top side and the bottom side of the food placement area 102. The two magnetic conduction connectors 500 are respectively located on the left side and the right side of the food placement area 102. Both ends of each magnetic conduction connector 500 are respectively connected to the plate-shaped part 210 and the magnetic field homogenizing plate 300. Further, the plate-shaped part 210, the magnetic field homogenizing plate 300 and the two magnetic conduction connectors 500 are all made of materials with good magnetic conductivity and heat conductivity, such as iron or steel. That is to say, the plate-shaped part 210 can also play the role of the magnetic field homogenizing plate, that is, it constitutes a magnetic field homogenizing plate, so that the plate-shaped part 210, the magnetic field homogenizing plate 300 and the two magnetic conduction connectors 500 together form an annular magnetic conduction path.

[0043] Preferably, the plate-shaped part 210 is provided with a plating layer, such as electro-galvanizing, etc., so as to improve the anti-corrosion ability of the plate-shaped part 210.

[0044] Refer to Figure 1 and Figure 2 As shown, the two magnetic field generating components 400 are respectively arranged corresponding to the plate-shaped part 210 and the magnetic field homogenizing plate 300. One magnetic field generating component 400 is arranged on the side of the plate-shaped part 210 facing the food placement area 102, and the other magnetic field generating component 400 is arranged on the side of the magnetic field homogenizing plate 300 facing the food placement area 102. The magnetic field generating component 400 can generate a magnetic field, so that the food placed in the food placement area 102 is affected by the magnetic field during storage. Moreover, the annular magnetic conduction path formed by the plate-shaped part 210, the magnetic field homogenizing plate 300 and the two magnetic conduction connectors 500 helps to concentrate the magnetic field in the food placement area 102 and improve the magnetic field uniformity.

[0045] It should be noted that a refrigerator generally has multiple compartments, and the multiple compartments can be used to achieve different functions, such as a refrigerating compartment, a freezing compartment, a variable-temperature compartment, etc. For the refrigerator of the present application, those skilled in the art can configure the specific number, functions and layout modes of the storage compartments according to needs. In addition, one compartment of the refrigerator can be used as a magnetic field fresh-keeping compartment, or multiple compartments of the refrigerator can be used as magnetic field fresh-keeping compartments. That is to say, a magnetic field homogenizing plate, a magnetic field generating component and a magnetic conduction connector can be arranged in one compartment of the refrigerator, or a magnetic field homogenizing plate, a magnetic field generating component and a magnetic conduction connector can be arranged in multiple compartments of the refrigerator.

[0046] In the solution of this embodiment, magnetic field homogenizing plates are respectively arranged on two opposite sides of the food placement area 102, and the plate-shaped part 210 of the fresh-keeping evaporator 200 is used to form one of the magnetic field homogenizing plates. First, the magnetic field generating component 400 generates a magnetic field in the food placement area 102, thereby playing a role in assisting the magnetic field for food storage and improving the fresh-keeping effect of the food. Specifically, when the magnetic field fresh-keeping compartment is used to implement the refrigeration function, the magnetic field can enable the food to not freeze at sub-zero low temperatures, greatly reducing the refrigeration temperature and increasing the storage duration and fresh-keeping effect. When the magnetic field fresh-keeping compartment is used to implement the freezing function, the magnetic field can enable small ice crystals to be formed when the food freezes, reducing the damage of the ice crystals to the food cells, thereby reducing the loss of food juice and improving the fresh-keeping effect.

[0047] Secondly, the magnetic field homogenizing plate can play a role in converging and guiding the magnetic field generated by the magnetic field generating component 400, thereby helping to improve the uniformity of the magnetic field in the food placement area 102. In addition, when the fresh-keeping evaporator 200 cools the food placement area 102, it can also act as a magnetic field homogenizing plate to converge and guide the magnetic field, which is beneficial to reducing material use and cost.

[0048] Furthermore, by using the magnetic conduction connecting piece 500 to connect the two magnetic field homogenizing plates, the two magnetic field homogenizing plates and the two magnetic conduction connecting pieces 500 form an annular magnetic conduction path. The annular magnetic conduction path can play a role in converging and guiding the magnetic field generated by the magnetic field generating component 400, thereby helping to concentrate the magnetic field in the food placement area 102, improving the magnetic field utilization rate and reducing the influence of the magnetic field on external devices, and also improving the uniformity of the magnetic field in the food placement area 102. At the same time, the cold quantity of the fresh-keeping evaporator 200 can be transmitted along the annular magnetic conduction path, thereby improving the refrigeration efficiency of the food placement area 102 and helping to improve the temperature uniformity of the food placement area 102.

[0049] By arranging the refrigerant pipeline 211 in the plate-shaped part 210, the plate-shaped part 210 can have more cold quantity, so that more cold quantity can be transmitted to the magnetic conduction connecting piece 500, that is, more cold quantity can be transmitted to the annular magnetic conduction path, thereby further improving the refrigeration efficiency of the food placement area 102.

[0050] It should be noted that in some other embodiments, the refrigerator can also be provided with one magnetic field generating component, and the magnetic field generating component is arranged on one side of one of the magnetic field homogenizing plates facing the food placement area. Preferably, two magnetic field generating components are provided, which can make the magnetic field more uniform.

[0051] In addition, it should be noted that in some other embodiments, the two magnetic field homogenizing plates can also be arranged on the left and right sides of the food placement area, and the two magnetic conduction connecting pieces are arranged on the top and bottom sides of the food placement area, or other positions that can make the two magnetic field homogenizing plates be arranged oppositely and the two magnetic conduction connecting pieces be arranged oppositely to form an annular magnetic conduction path.

[0052] It should be noted that in some other embodiments, the plate portion of the fresh-keeping evaporator may also be a solid plate structure, and the refrigerant pipeline is arranged on one side of the plate structure.

[0053] It should be noted that the magnetic field generating member may be an electromagnetic coil, and the energized electromagnetic coil generates a magnetic field; alternatively, the magnetic field generating member may also be a permanent magnet sheet.

[0054] Alternatively, in some embodiments, the magnetic field generating member is a component composed of an electromagnetic coil and a permanent magnet sheet. For example, as Figure 5 shown, the magnetic field generating member 400 includes an electromagnetic coil 410 and a permanent magnet sheet 420, and the electromagnetic coil 410 is attached to one side of the permanent magnet sheet 420. The electromagnetic coil 410 and the permanent magnet sheet 420 jointly generate a magnetic field.

[0055] It should be noted that electromagnetic coils can also be arranged on both sides of the permanent magnet sheet.

[0056] Alternatively, as Figure 6 shown, in some other embodiments, the magnetic field generating member 400 includes an electromagnetic coil 410 and a permanent magnet sheet 420, and the electromagnetic coil 410 surrounds the permanent magnet sheet 420. Specifically, the permanent magnet sheet 420 is arranged in the area surrounded by the electromagnetic coil 410. The permanent magnet sheet 420 may be smaller than the area surrounded by the electromagnetic coil 410 or exactly equal, so that the electromagnetic coil 410 is attached to the side of the permanent magnet sheet 420.

[0057] Referring to Figure 4 shown, preferably, the ratio of the projected area of the refrigerant pipeline 211 on the surface of the plate portion 210 facing the food placement area 102 to the area of the surface of the plate portion 210 facing the food placement area 102 is greater than or equal to 0.3 and less than or equal to 0.6. For example, it can be 0.3, 0.35, 0.4, 0.42, 0.5, 0.6, etc. Specifically, Figure 4 the area of the largest square area in Figure 4 is the area of the surface of the plate portion 210 facing the food placement area 102, and then

[0058] the planar area of the refrigerant pipeline 211 in

[0059] Referring to Figures 1 to 4As shown, further, the inlet 212 and the outlet 213 are arranged on the same side of the plate-shaped part 210. Moreover, the two magnetic field homogenizing plates are respectively arranged on the top side and the bottom side of the food placement area 102, such that the plate-shaped part 210 of the freshness preservation evaporator 200 that constitutes the magnetic field homogenizing plate is arranged horizontally. Specifically, the freshness preservation evaporator 200 is arranged on the top side of the food placement area 102, and the magnetic field homogenizing plate 300 is arranged on the bottom side of the food placement area 102. Both the inlet 212 and the outlet 213 of the refrigerant pipeline 211 are arranged on the side of the plate-shaped part 210 facing the rear side of the refrigerator.

[0060] By arranging the two magnetic field homogenizing plates on the top side and the bottom side of the food placement area 102 respectively, the plate-shaped part 210 of the freshness preservation evaporator 200 that constitutes the magnetic field homogenizing plate is arranged horizontally, so that the refrigerant pipeline 211 in the plate-shaped part 210 is arranged horizontally. Furthermore, the refrigerant flows horizontally in the refrigerant pipeline 211, such that the refrigerant does not need to overcome gravity, thus making it easier for the refrigerant to flow.

[0061] In addition, by arranging the inlet 212 and the outlet 213 on the same side of the plate-shaped part 210, the connection between the inlet 212 and the outlet 213 and the external pipeline is more convenient. Further, by arranging the inlet 212 and the outlet 213 on the side of the plate-shaped part 210 facing the rear side of the refrigerator, the inlet 212 and the outlet 213 are easier to connect to the pipeline at the rear side of the refrigerator and are more aesthetically pleasing.

[0062] It should be noted that in some other embodiments, the inlet and the outlet of the refrigerant pipeline can also be arranged on different sides of the plate-shaped part. For example, when the freshness preservation evaporator is arranged at the top of the food placement area, the inlet and the outlet can be arranged on the left side and the right side of the plate-shaped part respectively.

[0063] As Figure 3 shown, the freshness preservation evaporator 200 includes a heat dissipation part 220. The heat dissipation part 220 is connected to the plate-shaped part 210, and the heat dissipation part 220 is provided with a plurality of fins 221, thereby being able to improve the cold quantity release efficiency.

[0064] As Figure 7 and Figure 8 shown, in another embodiment, the refrigerator includes two freshness preservation evaporators 200. The plate-shaped parts 210 of the two freshness preservation evaporators 200 respectively constitute two magnetic field homogenizing plates. Specifically, the refrigerator includes a box body 100. The box body 100 forms a magnetic field freshness preservation compartment 101. A part of the space in the magnetic field freshness preservation compartment 101 serves as a food placement area 102 for placing food. The two freshness preservation evaporators 200 are respectively arranged on opposite sides of the food placement area 102. Specifically, the two freshness preservation evaporators 200 are respectively arranged at the top and the bottom of the food placement area 102, and the plate-shaped parts 210 of the two freshness preservation evaporators 200 are arranged oppositely.

[0065] Referring toFigure 7 and Figure 8 As shown in Figure 8 , further, the refrigerator includes two magnetic connectors 500. Both ends of the magnetic connectors 500 are respectively connected to the two plate-shaped parts 210, and the two magnetic connectors 500 are respectively located on opposite sides of the food placement area 102. Specifically, the two magnetic connectors 500 are respectively located on the left and right sides of the food placement area 102, and both ends of each magnetic connector 500 are respectively connected to the two plate-shaped parts 210. Further, both the plate-shaped part 210 and the magnetic connector 500 are made of materials with good magnetic conductivity and heat conductivity, such as iron or steel. That is to say, both of the two plate-shaped parts 210 function as magnetic field homogenizing plates, that is, a magnetic field homogenizing plate is formed, so that the two plate-shaped parts 210 and the two magnetic connectors 500 together form a circular magnetic conduction path.

[0066] Referring to Figure 7 and Figure 8 As shown in Figure 8 , the refrigerator includes two magnetic field generating parts 400. The two magnetic field generating parts 400 are respectively arranged corresponding to the two plate-shaped parts 210. One magnetic field generating part 400 is arranged on the side of the plate-shaped part 210 located at the top of the food placement area 102 facing the food placement area 102, and the other magnetic field generating part 400 is arranged on the side of the plate-shaped part 210 located at the bottom of the food placement area 102 facing the food placement area 102. The magnetic field generating part 400 can generate a magnetic field, so that the food placed in the food placement area 102 is affected by the magnetic field during storage. Moreover, the circular magnetic conduction path formed by the two plate-shaped parts 210 and the two magnetic connectors 500 helps to concentrate the magnetic field in the food placement area 102 and improve the magnetic field uniformity.

[0067] In the solution of this embodiment, by respectively arranging the fresh-keeping evaporators 200 on opposite sides of the food placement area 102, the plate-shaped parts 210 of the two fresh-keeping evaporators 200 form a magnetic field homogenizing plate, and the two plate-shaped parts 210 are connected by the magnetic connectors 500, so that the two plate-shaped parts 210 and the two magnetic connectors 500 form a circular magnetic conduction path. First, the magnetic field generating part 400 generates a magnetic field in the food placement area 102, thereby playing a magnetic field assistance role in food storage and improving the fresh-keeping effect of the food. Specifically, when the magnetic field fresh-keeping compartment is used to achieve the refrigeration function, the magnetic field can enable the food to not freeze at sub-zero low temperatures, greatly reducing the refrigeration temperature and increasing the storage duration and fresh-keeping effect. When the magnetic field fresh-keeping compartment is used to achieve the freezing function, the magnetic field can enable the food to form small ice crystals when freezing, reducing the damage of the ice crystals to the food cells, thereby reducing the loss of food juice and improving the fresh-keeping effect.

[0068] Secondly, the annular magnetic conduction path can converge and guide the magnetic field generated by the magnetic field generating element 400, thereby helping to concentrate the magnetic field in the food placement area 102, improving the magnetic field utilization rate and reducing the impact of the magnetic field on external devices, and moreover, improving the uniformity of the magnetic field in the food placement area 102. In addition, when the fresh-keeping evaporator 200 cools the food placement area 102, it can also serve as a magnetic field homogenizing plate to form an annular magnetic conduction path, reducing material usage and lowering costs. At the same time, the cooling capacity of the fresh-keeping evaporator 200 can be transmitted along the annular magnetic conduction path, thereby improving the refrigeration efficiency of the food placement area 102 and helping to improve the temperature uniformity of the food placement area 102.

[0069] It should be noted that in some other embodiments, the two fresh-keeping evaporators can also be arranged on the left and right sides of the food placement area, and the two magnetic conduction connectors are arranged on the top and bottom sides of the food placement area, or other positions that can make the two plate-shaped parts face each other and the two magnetic conduction connectors face each other to form an annular magnetic conduction path.

[0070] Refer to Figure 1 、 Figure 7 and Figure 9 As shown in

[0071] Refer to Figure 9 As shown, specifically, the outlet end of the compressor 700 is connected in series with the inlet end of the condenser 800. The outlet end of the condenser 800 is respectively connected to the inlet ends of the fresh-keeping evaporator 200 and the ordinary refrigeration evaporator 600 via the solenoid valve 900 to controllably realize the separate connection of the condenser 800 and the fresh-keeping evaporator 200, or the separate connection of the condenser 800 and the ordinary refrigeration evaporator 600, or the simultaneous connection of the condenser 800 with the fresh-keeping evaporator 200 and the ordinary refrigeration evaporator 600 through the solenoid valve 900. And, the outlet of the fresh-keeping evaporator 200 is communicated with the inlet of the ordinary refrigeration evaporator 600, so that the refrigerant flowing through the fresh-keeping evaporator 200 can flow through the ordinary refrigeration evaporator 600.

[0072] Refer to Figure 9As shown, specifically, during the refrigeration process, the refrigerant flows from the compressor 700 to the condenser 800, and then to the solenoid valve 900. The two outlets of the solenoid valve 900 lead to the fresh-keeping evaporator 200 and the ordinary refrigeration evaporator 600 respectively, and the solenoid valve 900 has three outlet states. Among them, one state is that the opening leading to the fresh-keeping evaporator 200 is open, and the opening leading to the ordinary refrigeration evaporator 600 is closed, so that the refrigerant from the condenser 800 flows to the fresh-keeping evaporator 200 alone, thereby refrigerating the magnetic field fresh-keeping compartment. At the same time, the refrigerant flowing through the fresh-keeping evaporator 200 can flow through the ordinary refrigeration evaporator 600, playing a certain refrigeration effect on the ordinary compartment.

[0073] One state is that the opening leading to the ordinary refrigeration evaporator 600 is open, and the opening leading to the fresh-keeping evaporator 200 is closed, so that the refrigerant from the condenser 800 flows to the ordinary refrigeration evaporator 600 alone, thereby refrigerating the ordinary compartment. One state is that the opening leading to the fresh-keeping evaporator 200 is open, and the opening leading to the ordinary refrigeration evaporator 600 is open, so that the refrigerant from the condenser 800 can flow to the fresh-keeping evaporator 200 and the ordinary refrigeration evaporator 600 respectively, thereby refrigerating the magnetic field fresh-keeping compartment and the ordinary compartment simultaneously.

[0074] The above structure enables the refrigerant flowing through the fresh-keeping evaporator 200 to also flow through the ordinary refrigeration evaporator 600, so that while refrigerating the magnetic field fresh-keeping compartment, it can refrigerate the ordinary compartment, which helps to maintain the low temperature of the ordinary compartment, reduce the frequency of the ordinary compartment reaching the startup point, thereby reducing the compressor startup frequency and avoiding frequent start and stop of the compressor.

[0075] It should be noted that in some other embodiments, it can also be that the refrigerant first flows through the ordinary refrigeration evaporator, and the refrigerant flowing out of the ordinary refrigeration evaporator enters the fresh-keeping evaporator.

[0076] At this point, those skilled in the art should recognize that although multiple exemplary embodiments of the present invention have been shown and described in detail herein, still, without departing from the spirit and scope of the present invention, many other variations or modifications that conform to the principles of the present invention can be directly determined or derived based on the content disclosed in the present invention. Therefore, the scope of the present invention should be understood and determined to cover all these other variations or modifications.
