Description

Technical Field

[0001] This invention relates to the field of range hood technology, and more specifically to a refrigerated range hood. Background Technology

[0002] Range hoods are generally used to exhaust cooking fumes from indoors to outdoors. Because cooking involves heating, the temperature within the cooking area can easily rise, reducing the user's cooking experience. To address this issue, a type of cooling range hood has been developed, integrating a cooling function to help lower the temperature within the cooking area. However, in existing cooling range hoods, the heat dissipation vent is directly connected to the exhaust duct, making it susceptible to the influence of cooking fumes within the duct, leading to condenser contamination.

[0017] Optionally, the housing includes a partition disposed within the smoke exhaust duct, the partition extending along the air supply direction of the smoke exhaust duct to define the first air inlet section and the second air inlet section within the smoke exhaust duct.

[0018] Optionally, each of the air inlet sections is provided with an air inlet;

[0019] The partition is arranged in a curved extension from one edge of the air inlet toward the middle of the smoke exhaust duct and the air supply direction.

[0023] Optionally, the first fan is located at the connection between the first air inlet section and the second air inlet section.

[0024] Optionally, the housing includes a partition disposed within the exhaust duct, the partition defining the first air inlet section and the second air inlet section;

[0025] The partition is connected to the volute of the first fan and extends toward the air inlet to connect with the inner wall of the exhaust duct, and / or extends away from the air inlet.

[0026] Optionally, the cooling module further includes a second fan, which is located in the heat dissipation duct.

[0027] Optionally, the housing also forms a cooling air duct;

[0028] The refrigeration module also includes an evaporator, which is located inside the refrigeration duct.

[0029] Optionally, the cooling air duct is provided with a cooling inlet, the heat dissipation air duct is provided with a heat dissipation inlet, and the first air inlet section is provided with a first air inlet;

The second air inlet section is connected to the heat dissipation outlet, which can promptly introduce the heat dissipation airflow into the exhaust duct before it exchanges heat with the indoor environment. With the help of the first fan in the exhaust duct, the heat dissipation airflow and the fumes are driven to be discharged together from the exhaust duct, which helps to promote the heat dissipation of the condenser and reduce the impact of the heat dissipation airflow on the temperature rise of the refrigerated range hood. Since the two air inlet sections are independent of each other, the heat dissipation airflow and fumes flowing in the two air inlet sections do not interfere with each other, which helps to reduce the possibility of fumes entering the heat dissipation duct and contaminating the condenser. Compared with the solution of setting a filter device at the connection between the heat dissipation duct and the exhaust duct, it helps to reduce the wind resistance of the heat dissipation duct, effectively simplifies the structure of the whole machine, reduces the overall cost, and improves the performance of the refrigerated range hood.

[0048] Range hoods are generally used to exhaust cooking fumes from indoors to outdoors. Because cooking involves heating, the temperature within the cooking area can easily rise, reducing the user's cooking experience. To address this issue, a cooling range hood has been developed, integrating a cooling function to help lower the temperature within the cooking area. However, in existing cooling range hoods, the heat dissipation vent is directly connected to the exhaust duct, making it susceptible to contamination from cooking fumes within the duct, leading to oil fume contamination of the condenser components.

[0049] In view of the above, the present invention provides a refrigerated range hood. Please refer to [link / reference]. Figures 1 to 4 The attached figures illustrate specific embodiments of the refrigerated range hood provided by the present invention.

[0050] Please see Figures 1 to 4 The refrigerated range hood 1 provided by the present invention includes a housing 100, a fume extraction module 200, and a refrigeration module 300. The housing 100 forms an exhaust duct 111 and a heat dissipation duct 121. The exhaust duct 111 includes at least two independent air inlet sections, namely a first air inlet section 111a and a second air inlet section 111b. The fume extraction module 200 includes a first fan 210 disposed in the exhaust duct 111. The refrigeration module 300 includes a condenser 310 disposed in the heat dissipation duct 121. The first air inlet section 111a is used to receive fumes, and the second air inlet section 111b is connected to the heat dissipation duct 121.

[0051] In the technical solution provided by this invention, the first air inlet section 111a of the exhaust duct 111 is used to receive the fumes generated during cooking, thereby realizing the exhaust function of the refrigeration range hood 1. The second air inlet section 111b is connected to the heat dissipation outlet 121b, which can promptly introduce the heat dissipation airflow into the exhaust duct 111 before it exchanges heat with the indoor environment. With the help of the first fan 210 in the exhaust duct 111, the heat dissipation airflow and fumes are driven to be discharged together from the exhaust duct 111, thereby helping to promote the condenser 310. Heat dissipation is achieved, and the impact of the heat dissipation airflow on the temperature rise of the cooling range hood 1 is reduced. Since the two air inlets are independent of each other, the heat dissipation airflow and oil fumes flowing through the two air inlets do not interfere with each other, which helps to reduce the possibility of oil fumes entering the heat dissipation air duct 121 and contaminating the condenser 310. Compared with the scheme of setting a filter device at the connection between the heat dissipation air duct 121 and the exhaust air duct 111, it helps to reduce the wind resistance of the heat dissipation air duct 121, which can effectively simplify the structure of the whole machine, reduce the overall cost, and improve the performance of the cooling range hood 1.

[0052] In this design, the refrigerated range hood 1 refers to a range hood that integrates at least refrigeration and smoke extraction functions, and is generally used in kitchens.

[0053] The casing 100 has an independent exhaust duct 111 and a heat dissipation duct 121 inside.

[0054] It is understood that the exhaust duct 111 has an air inlet and an air outlet 111e. The air inlet is used to communicate with the indoor environment, and at least one of the air inlets is directed towards the stove and can receive the fumes generated during the cooking process. The air outlet 111e is used to communicate with a common flue, so that the fumes generated indoors enter through the air inlet, flow through the exhaust duct 111, and are finally discharged from the air outlet 111e to the common flue.

[0055] In the smoke exhaust duct 111, the duct section that connects to the air inlet and is closer to the air inlet than the air outlet 111e is called the air inlet section. The smoke exhaust duct 111 includes at least two air inlet sections, and the two air inlet sections are independently arranged. It should be noted that "independent" does not limit the connection relationship between the two air inlet sections at the ports, but at least restricts the two air inlet sections from being interconnected in the middle to generate airflow exchange. When the two air inlet sections are independent, at least the airflow connected in each air inlet section can flow along its respective air supply direction without interfering with each other.

[0056] For ease of understanding, in the following embodiments, the air intake section used to access the oil fumes at the stove is defined as the first air intake section 111a, and the air intake section connected to the heat dissipation duct 121 is defined as the second air intake section 111b; in addition, in the following embodiments, the two air intake sections generally refer to the first air intake section 111a and the second air intake section 111b.

[0057] The fume extraction module 200 includes at least a first fan 210 disposed in the exhaust duct 111. The first fan 210 is used to drive the gas (fumes and / or air) in the exhaust duct 111 to flow along a set path, thereby increasing the ventilation volume and ventilation speed of the exhaust duct 111.

[0058] It is understood that the heat dissipation duct 121 has a heat dissipation inlet 121a and a heat dissipation outlet 121b. The heat dissipation inlet 121a and the heat dissipation outlet 121b are generally used to communicate with the indoor environment, so that indoor air can enter from the heat dissipation inlet 121a, flow through the heat dissipation duct 121, and finally be discharged into the indoor environment from the heat dissipation outlet 121b.

[0059] At least some of the functional components of the cooling range hood 1 are arranged within the heat dissipation duct 121, such as the condenser 310 in the cooling module 300. After the condenser 310 has been in operation for a set period, it tends to generate heat. If this heat accumulates near the condenser 310, it can cause the operating temperature of the condenser 310 to rise continuously, reducing its performance. When air flows through the heat dissipation duct 121, heat is exchanged with the air passing through the duct, raising its temperature and forming a cooling airflow. This cooling airflow can carry away the heat generated by the condenser 310, but after being discharged into the indoor environment from the heat dissipation outlet 121b, it can easily cause the temperature of the indoor environment where the cooling range hood 1 is located to rise.

[0060] By connecting the second air inlet section 111b with the heat dissipation duct 121, the heat dissipation airflow can be promptly introduced into the exhaust duct 111 by utilizing the oil fumes flowing in the first air inlet section 111a. This reduces the impact of the heat dissipation airflow on the indoor environment where the cooling range hood 1 is located, and ensures the continuous flow of heat dissipation airflow in the heat dissipation duct 121, which helps to enhance the heat dissipation effect at least at the condenser 310.

[0061] It should be noted that, in one embodiment, the exhaust duct 111 may include two sub-ducts extending along the air supply direction and arranged side by side, with each sub-duct's duct section near the air inlet defining an air inlet section. That is, the two sub-ducts remain completely independent, so that the fumes and heat dissipation airflows flowing through each sub-duct do not communicate or interfere with each other before entering the common exhaust duct.

[0062] Of course, in one embodiment, the exhaust duct 111 can be divided into two duct sections (i.e., two air inlets) only near the air inlet, with the remaining portion connected to each of the two air inlets to form an exhaust section. Based on this, the connection between the heat dissipation duct 121 and the second air inlet section 111b is located at least within the second air inlet section 111b, not within the exhaust section. This ensures that when the heat dissipation airflow enters the exhaust duct 111, it flows through at least the remaining duct section of the second air inlet section 111b before entering the exhaust section, where it merges with the fumes entering through the first air inlet section 111a and is discharged. With this configuration, the fumes in the first air inlet section 111a must flow sequentially through the exhaust section and the second air inlet section 111b before entering the heat dissipation duct 121 and contaminating the condenser 310. This increases the path length and tortuousness of the fumes entering and exiting the heat dissipation duct 121, thereby preventing fumes from contaminating the condenser 310 to a certain extent.

[0063] The arrangement of the two sub-air ducts and two air inlet sections within the casing 100 is not limited. Taking the two air inlet sections as an example, the two air inlet sections can extend side by side in the same direction, or they can be inclined towards each other along their respective air supply directions, forming an inverted Y-shape together with the air outlet section. Any of the aforementioned air ducts or air duct sections can be straight or arc-shaped with at least one bend.

[0064] In view of the above, each of the air inlet sections is provided with an air inlet, the air inlet of the first air inlet section 111a is the first air inlet 111c, and the air inlet of the second air inlet section 111b is the second air inlet 111d.

[0065] In one embodiment, the heat dissipation outlet 121b of the heat dissipation duct 121 can be directly formed on the shell structure of the first air inlet section 111a. That is, the heat dissipation duct 121 is connected to and directly connected to the first air inlet section 111a, so that the heat dissipation airflow discharged through the heat dissipation duct 121 directly enters the first air inlet section 111a, avoiding the heat dissipation airflow from affecting the indoor environment by raising the temperature.

[0066] Of course, in another embodiment, the heat dissipation outlet 121b of the heat dissipation duct 121 can be independently set with the second air inlet 111d, which are close enough to each other and interconnected. This allows the heat dissipation airflow discharged through the heat dissipation outlet 121b to briefly enter the indoor environment before entering the second air inlet section 111b through the second air inlet 111d. In this way, the correlation between the heat dissipation duct 121 and the smoke exhaust duct 111 in terms of layout can be reduced as much as possible, giving them more options for layout. Furthermore, conventional range hoods can have multiple smoke inlets (i.e., multiple air inlets in this embodiment) on the body to achieve multi-directional smoke extraction. By setting the heat dissipation outlet 121b and the second air inlet 111d alternately, it can be used for various types of range hoods, reducing manufacturing costs.

[0067] Furthermore, in one embodiment, the air inlets of the two air inlet sections are oriented differently, that is, the first air inlet 111c and the second air inlet 111d are oriented differently. This arrangement ensures that when the first air inlet 111c faces the stove to receive the fumes generated by the stove, the second air inlet 111d is offset from the stove, reducing or even completely eliminating the entry of fumes into the second air inlet 111d, thereby preventing fumes from contaminating the condenser 310 within the heat dissipation duct 121.

[0068] Furthermore, in one embodiment, the two air inlets are respectively located on opposite sides of the housing 100. In any dimensional direction of the housing 100, the distance between the opposite side walls is longer and they face opposite directions. By setting the first air inlet 111c and the second air inlet 111d on the opposite side walls of the housing 100, the first air inlet 111c and the second air inlet 111d can be sufficiently separated, increasing the path length and circulation difficulty of the fumes at the first air inlet 111c entering the second air inlet 111d through the exhaust duct 111, i.e., the indoor environment.

[0069] Furthermore, since in actual use, the refrigerated range hood 1 is generally installed above the stove and on the wall above the stove, the front and lower sides of the refrigerated range hood 1 are generally closer to the stove. Therefore, in one embodiment, the first air inlet 111c is located on the front side of the housing 100 and tilted downwards. That is, the first air inlet 111c is located on the front side of the housing 100 and gradually tilts downwards in the rear direction. This arrangement can maximize the ventilation area of ​​the first air inlet 111c within the limited front-rear dimensions of the refrigerated range hood 1, thereby increasing the air volume and speed of the fumes entering the first air inlet 111c and improving the smoke extraction efficiency. Meanwhile, the second air inlet 111d is located on the rear side of the housing 100. On the one hand, the location of the second air inlet 111d on the rear side can increase the distance and angle between it and the first air inlet 111c, thus significantly reducing the possibility of oil fumes entering the second air inlet 111d. On the other hand, by placing the second air inlet 111d on the rear side of the housing 100, in order to get close enough to the second air inlet 111d, the heat dissipation outlet 121b is generally also located on the rear side of the housing 100, or is set towards the rear of the housing 100, so that the heat dissipation airflow will not blow directly on the user and will not directly raise the temperature of the area where the user is located.

[0070] Of course, when the first air inlet 111c is located on the rear side of the housing 100, the second air inlet 111d can also be located on the front or side of the housing 100, which will not be elaborated here.

[0071] Furthermore, this design does not restrict the vertical orientation of the first air inlet 111c and the second air inlet 111d; they can be positioned on the same horizontal plane. Alternatively, in one embodiment, the second air inlet 111d is positioned above the first air inlet 111c. It is understood that cooking fumes are generally lightweight and rise upwards. Since the refrigerated range hood 1 is typically positioned above the stovetop, by positioning the second air inlet 111d above the first air inlet 111c, the rising cooking fumes first approach the first air inlet 111c and are fully introduced by it. Only a small amount or almost no cooking fumes remain to continue rising to the second air inlet 111d, thereby further reducing the impact of cooking fumes at the second air inlet 111d.

[0072] Furthermore, when the first air inlet 111c extends forward and downward at an angle, the second air inlet 111d can also be set to extend backward and upward at an angle, so that the angle between the second air inlet 111d and the first air inlet 111c is fully expanded in the vertical direction.

[0073] In one embodiment, the ventilation cross-sectional area of ​​the first air inlet section 111a as a whole or near the first air inlet 111c can be increased to form a smoke collection chamber, which can increase the amount of oil fumes entering the chamber.

[0074] The two air inlet sections of the smoke exhaust duct 111 can be integrally formed within the casing 100, or please refer to [the relevant documentation]. Figures 2 to 3 In one embodiment, the housing 100 includes a partition 140 disposed within the smoke exhaust duct 111. The partition 140 extends along the air supply direction of the smoke exhaust duct 111 to define two air inlet sections within the smoke exhaust duct 111.

[0075] The shape, size, and material of the partition 140 are not limited and can be set according to actual needs. The partition 140 can be integrally formed with the housing 100 at the smoke exhaust duct 111, or it can be separately set from the housing 100. When the partition 140 and the housing 100 are separately set, the connection method between the two is not limited. It can be a fixed connection method such as welding, or a detachable connection method such as snap-fit ​​fixing, screw fixing, adsorption fixing, or adhesive fixing.

[0076] In one embodiment, the partition 140 may be fixed relative to the housing 100 when assembled into the housing 100, such that the length and ventilation cross-sectional area of ​​the two air inlet sections defined by the partition 140 and the housing 100 remain fixed.

[0077] In another embodiment, the partition 140 is adjustable relative to the housing 100. Specifically, for example, the partition 140 can be adjusted to move horizontally along the air supply direction within the exhaust duct 111, allowing the lengths of the two separated air inlet sections to be adjusted; or, the partition 140 can be adjusted to move radially along the exhaust duct 111, allowing the ventilation cross-sectional area of ​​each of the two separated air inlet sections to be adjusted. It should be noted that the partition 140 can be configured to maintain a sealed connection with the housing 100 during its adjustment stroke.

[0078] Further, please refer to Figure 2 The partition 140 extends and bends from one edge of the air inlet toward the middle of the smoke exhaust duct 111 and the air supply direction. Taking the second air inlet 111d as an example, after extending from one edge away from the air outlet 111e toward the middle of the smoke exhaust duct 111, the second air inlet 111d bends and extends toward the air supply direction to form the partition 140. That is, one end of the partition 140 is connected to one edge of the second duct, and the other end can be a free end or connected to the air outlet 111e.

[0079] The connection between the partition 140 and the second air inlet 111d forms an air guide section 141. The air guide section 141 has a windward surface, and at least the windward surface of the air guide section 141 is arranged in an arc shape, which can guide the heat dissipation airflow entering the second air inlet 111d, so that it can be redirected and circulated more smoothly towards the air outlet 111e.

[0080] Next, a baffle 140 is provided inside the smoke exhaust duct 111. The orthographic projection of the baffle 140 on the shell wall where the first air inlet 111c is located at least covers the first air inlet 111c; and / or, the orthographic projection of the baffle 140 on the shell wall where the second air inlet 111d is located at least covers the second air inlet 111d. That is, when the exhaust duct 111 supplies air from bottom to top, the extension height of the baffle 140 within the exhaust duct 111 is at least higher than the first air inlet 111c and / or the second air inlet 111d. This prevents the oil fumes or heat dissipation airflow from flowing directly along the line connecting the first air inlet 111c and the second air inlet 111d. Instead, the oil fumes must bypass the baffle 140 upwards. As a result, the oil fumes cannot approach the second air inlet 111d, increasing the possibility of contamination of the condenser 310. At the same time, the heat dissipation airflow cannot flow to the first air inlet 111c, causing air blockage at the first air inlet 111c. This results in increased air resistance at the first air inlet 111c, reducing the exhaust efficiency.

[0081] Based on any of the above embodiments, the first fan 210 is located at the connection between the two air inlet sections. Specifically, the first fan 210 can be located in the air outlet section, or sealed and connected at any point between the two air inlet sections. In this way, when the first fan 210 is working, it can simultaneously act on both air inlet sections, guiding the oil fumes in the first air inlet section 111a and the heat dissipation airflow in the second air inlet section 111b to flow simultaneously to the common flue, accelerating their discharge.

[0082] Next, as described above, the housing 100 includes a partition 140 disposed within the exhaust duct 111, the partition 140 defining two air inlet sections; the partition 140 is connected to the volute of the first fan 210 and extends toward the air inlet to connect with the inner wall of the exhaust duct 111, and / or extends away from the air inlet, i.e., toward the air outlet 111e. The partition 140 is adapted to the arrangement position of the first fan 210 and can be a single plate or at least two plates, all of which are sealed to the volute of the first fan 210.

[0083] Of course, to increase the airflow volume and velocity of the cooling airflow, in one embodiment, the cooling module 300 further includes a second fan 311, which is disposed in the cooling duct 121. The second fan 311 is used to drive the cooling airflow toward the second air inlet 111d. The second fan 311 can be disposed in the cooling duct 121 near the cooling outlet 121b to sufficiently increase the airflow volume and velocity of the cooling airflow discharged from the cooling outlet 121b, thereby enabling the cooling airflow to flow more quickly and in greater quantities toward the second air inlet 111d and be connected to the second air inlet 111d.

[0084] It should be noted that when the second fan 311 is provided, the first fan 210 can be provided at the connection between the first air inlet section 111a and the second air inlet section 111b as described above, or in one embodiment, the first fan 210 is provided in the first air inlet section 111a, and the second air inlet section 111b is provided near the second air inlet 111d.

[0085] Furthermore, based on any of the above embodiments, the housing 100 also forms a cooling air duct 131, and the cooling air duct 131, the smoke exhaust air duct 111, and the heat dissipation air duct 121 are independently arranged. The cooling module 300 also includes an evaporator 320, which is disposed within the cooling air duct 131.

[0086] It is understood that the refrigeration duct 131 also has a refrigeration inlet 131a and a refrigeration outlet 131b. The refrigeration outlet 131b is used to connect to the indoor environment, and the refrigeration inlet 131a can connect to the indoor environment to access indoor air, or it can connect to the outdoor environment to access outdoor fresh air. The refrigeration module 300 generally includes a condenser 310, an evaporator 320, and a compressor 330 connected by refrigerant pipes to form a refrigeration circuit. The evaporator 320 is located in the refrigeration duct 131, and a water collection tray 340 can also be installed below the evaporator 320. During operation, the evaporator 320 can cool the air passing through it, or provide a cool airflow at a lower temperature. The cool airflow is discharged into the indoor environment, which can at least cool the area where the range hood 1 is located, improving the user experience.

[0087] In view of the above, in one embodiment, the cooling inlet 131a and the heat dissipation inlet 121a are located above the first air inlet 111c. Similarly, this can reduce the impact of oil fumes on the cooling inlet 131a and the heat dissipation inlet 121a.

[0088] The refrigeration outlet 131b can be located above the refrigeration inlet 131a. Since the refrigeration airflow is generally heavier, it naturally flows downward after being blown out. By setting the refrigeration outlet 131b above the refrigeration inlet 131a and the first air inlet 111c, the entire heated area can be cooled during the entire flow of the refrigeration airflow, thereby increasing the cooling effect.

[0089] Please see Figures 1 to 4 In one embodiment, the housing 100 includes a main housing 110 forming the exhaust duct 111 and two heat exchange housings. A smoke collection hood 112 extends laterally from the lower portion of the main housing 110. The smoke collection hood 112 has an upward-facing support surface 112a. The smoke collection hood 112 at least partially defines the air inlet section for receiving oil fumes. Specifically, the smoke collection chamber described above can be formed inside the smoke collection hood 112. Because the smoke collection hood 112 is a stepped structure of the main housing 110, an upward-facing support surface 112a can be formed at the lateral extension. The support surface 112a can be formed on at least one side of the main housing 110, or extended along the circumferential direction of the main housing 110 to form a closed ring.

[0090] Two heat exchange housings are disposed on opposite sides of the main housing 110 and supported and fixed on the support surface 112a. One heat exchange housing defines the heat dissipation duct 121, and the other heat exchange housing defines the cooling duct 131. For ease of understanding, the heat exchange housing defining the heat dissipation duct is defined as the first heat exchange housing 120, and the heat exchange housing defining the cooling duct 131 is defined as the second heat exchange housing 130.

[0091] The first heat exchange shell 120 and the second heat exchange shell 130 are respectively disposed on opposite sides of the main shell 110, specifically on opposite sides of the main shell 110 along its length direction, and their structures can be basically symmetrical about the main shell 110 to increase the stability of the center of gravity and the aesthetics of the structure of the whole machine.

[0092] At least one of the first heat exchange shell 120 and the second heat exchange shell 130 may be integrally formed with the main shell 110, or may be separately connected. When the heat exchange shell and the main shell 110 are separately connected, the connection method can be welding or a detachable connection. The detachable connection method is not limited and can be one or more of the following: screw fixing, snap-fit ​​fixing, adhesive fixing, and adsorption fixing. This allows for independent assembly and replacement of the main shell 110 and any heat exchange shell.

[0093] In practical applications, the refrigeration inlet 131a and the heat dissipation inlet 121a can be respectively arranged on the side of the second heat exchange shell 130 and the first heat exchange shell 120 that are far apart from each other; the refrigeration outlet 131b can be arranged on the top of the second heat exchange shell 130 and the air outlet faces forward; the heat dissipation outlet 121b can be arranged on the rear side of the first heat exchange shell 120 and the air outlet faces rearward.

[0094] Alternatively, in one embodiment, the back plate of the main housing 110 is located in front of the back plate of the heat exchange housing; the heat dissipation outlet 121b is located on the side of the first heat exchange housing 120 facing the main housing 110. When the back plates of the first heat exchange housing 120 and / or the second heat exchange housing 130 are sufficiently close to and installed against the wall, the main housing 110 maintains a gap with the wall at least at the location of the first air inlet 111c, forming a space connecting the first air inlet 111c and the heat dissipation outlet 121b. Based on this, the heat dissipation outlet 121b is arranged laterally towards the main housing 110, enabling it to exhaust air towards the first air inlet 111c and reducing the obstruction of the heat dissipation outlet 121b by the wall.

[0095] The evaporator 320 can be arranged radially along the refrigeration duct 131, perpendicular to the duct wall at its location, or inclined relative to the airflow direction of the refrigeration duct 131, to increase the evaporation area. The condenser 310 is arranged similarly to the evaporator 320. The compressor 330 is located adjacent to the condenser 310, for example, at the first heat exchange housing 120.

Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
