Description

Technical Field

[0001] The utility model relates to the technical field of HVAC equipment, in particular to a diversion component and HVAC equipment. Background Art

[0002] For HVAC equipment, there are generally two modes: cooling mode and heating mode. At this time, the cooling mode and heating mode are both for the indoor heat exchanger. When the indoor heat exchanger is in cooling mode or heating mode, the outdoor heat exchanger is in heating mode and cooling mode respectively.

[0003] In cooling mode, the compressor compresses the low-temperature, low-pressure refrigerant to a high-temperature, high-pressure state. The refrigerant then flows into the outdoor heat exchanger, where it condenses into a high-pressure, medium-temperature liquid refrigerant. This liquid refrigerant then passes through a throttling component, transforming it into a low-temperature, low-pressure, two-phase refrigerant. This two-phase refrigerant then flows through a distributor before entering the indoor heat exchanger. The distributor distributes the two-phase refrigerant according to the refrigerant demand for each flow path, and then enters the indoor heat exchanger for heat exchange, achieving the cooling effect. In this case, the outdoor heat exchanger acts as the condenser, and the indoor heat exchanger acts as the evaporator. After heat exchange, the low-temperature, low-pressure refrigerant ultimately enters the return air port of the compressor for subsequent circulation. In heating mode, the compressed refrigerant first enters the indoor heat exchanger for condensation. In this case, the indoor heat exchanger acts as the condenser, while the outdoor heat exchanger acts as the evaporator. The distributor distributes the liquid or gaseous refrigerant flowing from the condenser to the evaporator.

[0004] At present, the distributor is connected to the distribution pipe by welding. However, in order to ensure the quality of welding, it is generally necessary to ensure that there is a certain overlap depth or overlap area between the distributor and the distribution pipe. This results in the part where the distributor and the distribution pipe are connected having a thicker thickness, and the reliability of the resulting overlap structure is also poor.

[0056] like Figure 1-Figure 7As shown, the first aspect of the present invention proposes a diverter assembly 1000, which is used for a HVAC device 1. Specifically, the HVAC device 1 may include a compressor 4000, a valve structure, a first heat exchanger 2000, and a second heat exchanger 3000 that are connected to each other. The compressor 4000 is used to compress the refrigerant. The refrigerant compressed by the compressor 4000 can flow through the second heat exchanger 3000 and the first heat exchanger 2000 in sequence, and finally flow back to the compressor 4000. The valve structure includes a four-way valve 6000. The four-way valve 6000 has four connecting ports, two of which are connected to the output end and the input end of the compressor 4000 respectively, and the other two connecting ports are connected to the input end of the second heat exchanger 3000 and the output end of the first heat exchanger 2000 respectively.

[0057] Among them, the first heat exchanger 2000 and the second heat exchanger 3000 can enable the HVAC equipment 1 to switch between the two functions of evaporator and condenser to operate. In this case, one of the first heat exchanger 2000 and the second heat exchanger 3000 is set outside the target space and used as an outdoor unit, and the other is installed in the target space and used as an indoor unit. The outdoor unit and the indoor unit work together to form a circulation flow path, so that the HVAC equipment 1 can cool, heat, dehumidify and purify the air in the target space, thereby achieving a comfortable target space. Among them, the HVAC equipment 1 can have one outdoor unit and multiple indoor units, and this embodiment of the application does not specifically limit this.

[0058] In this embodiment, HVAC equipment 1 is an air conditioner (in other embodiments of the present invention, HVAC equipment 1 includes but is not limited to a multi-split unit, a heat pump, a water heater, a swimming pool unit, etc.), first heat exchanger 2000 is an evaporator, and second heat exchanger 3000 is a refrigerator. First heat exchanger 2000 and second heat exchanger 3000 are connected by a flow diversion assembly 1000 to divert refrigerant from the gas / liquid main flow to multiple heat exchanger blocks. The valve structure also includes a refrigeration throttle valve 5000, which is disposed between the flow diversion assembly 1000 and the second heat exchanger 3000.

[0059] In terms of overall design, Figure 1-Figure 4 As shown, the flow diversion assembly 1000 includes a distributor 100 and a first connecting tube 200. The distributor 100 has an inlet port 111 and multiple diversion ports 201, each of which is connected to the inlet port 111. Each diversion port 201 is connected to a corresponding first connecting tube 200. A first flange 210 is provided on the end of the first connecting tube 200 facing the distributor 100. The first flange 210 surrounds the first connecting tube 200 and is securely connected to the distributor 100.

[0060] Specifically, providing the first flange 210 on the first connecting tube 200 increases the welding area between the first connecting tube 200 and the distributor 100, improving welding reliability and thus resolving the poor reliability issue of the existing distributor-distribution tube overlap structure. Furthermore, providing the first flange 210 on the first connecting tube 200 eliminates the need for the distributor 100 to incorporate a structure that mates with the first connecting tube 200, simplifying the structure of the distributor 100 and reducing structural requirements for the distributor 100.

[0061] It should be understood that in this embodiment, the distributor 100 is a columnar structure, one end of the distributor 100 is provided with an inflow hole 111, and the other end of the distributor 100 is provided with a mounting surface, the mounting surface is provided with a plurality of diversion holes 201, and the plurality of diversion holes 201 are connected to the inflow hole 111. At the same time, the first connecting tube 200 has a first end close to the distributor 100 and a second end away from the distributor 100, and the plurality of first connecting tubes 200 are arranged corresponding to the plurality of diversion holes 201. The first end of the first connecting tube 200 is provided with a first flange 210, which is arranged on the outer side surface of the first connecting tube 200 and extends radially along the first connecting tube 200. The end of the first flange 210 facing the distributor has an active surface that is fitted and connected to the mounting surface. At this time, the first flange 210 and the distributor 100 can be welded and fixed, and the first connecting tube 200 is concentrically arranged with the corresponding diversion hole 201. The setting of the first flange 210 increases the welding area between the first connecting pipe 200 and the distributor 100, improves the connection effect between the distributor 100 and the distribution pipe, helps to increase the service life of the diversion component 1000, and further increases the service life of the HVAC equipment 1, reduces the maintenance frequency of the HVAC equipment 1 during use, and improves the use effect of the HVAC equipment 1.

[0062] It should be noted that in this embodiment, the plurality of diversion holes 201 are arranged around the axis of the distributor 100 and at intervals, and the first flanges 210 of the plurality of first connecting pipes 200 are arranged at intervals to ensure a good welding space.

[0063] In addition, the shape of the first flange 210 can be set to be square, circular, elliptical, triangular, pentagonal, hexagonal, diamond, etc., so as to increase the welding area.

[0064] The distributor 100 further includes a housing 10 and a plate 20. The housing 10 has an expansion cavity 103 communicating with the inlet port 111. The plate 20 is connected to the housing 10 and is located on the side of the expansion cavity 103 facing away from the inlet port 111. The plate 20 is provided with a plurality of diverter holes 201, which are arranged around the inlet port 111.

[0065] Specifically, by limiting the shell 10 of the distributor 100 to have an expansion cavity 103, the flow rate of the refrigerant after entering the expansion cavity 103 from the inlet hole 111 can be slowed down to enable preliminary mixing. At the same time, by limiting the plurality of diversion holes 201 to be arranged around the inlet hole 111 as the center, the paths of the refrigerant flowing from the inlet hole 111 to each diversion hole 201 can be the same, which helps to ensure the content of the refrigerant flowing to each diversion hole 201, and further ensure the diversion effect of the distributor 100.

[0066] It is important to understand that if Figure 4-Figure 6 As shown, the shell 10 is generally tubular, with an inflow hole 111 defined at the bottom of the shell 10 and a diverter cavity defined inside the shell 10. The diverter cavity has an open opening. In this embodiment, the diverter cavity includes an expansion cavity 103 and a mounting cavity 104. The inflow hole 111 and the mounting cavity 104 are respectively provided at both ends of the expansion cavity 103. The inner diameter of the expansion cavity 103 gradually increases from the inflow hole 111 toward the mounting cavity 104, i.e., the flow direction of the refrigerant. Optionally, the expansion cavity 103 is configured as a hemispherical structure. The minimum inner diameter of the expansion cavity 103 is the same as the aperture of the inflow hole 111, and the maximum inner diameter of the expansion cavity 103 is the same as the aperture of the mounting cavity 104. The mounting cavity 104 is connected to the outside and forms an open opening of the diverter cavity. The refrigerant entering the expansion cavity 103 from the inflow hole 111 changes its flow direction due to the change in the flow space. On the one hand, the refrigerant can be mixed in the expansion cavity 103, thereby improving the mixing effect. On the other hand, the change in the aperture of the expansion cavity 103 can guide the flow of the refrigerant, and further cooperate with the diversion hole 201 described below to ensure that the refrigerant flows to the diversion hole 201 evenly and quickly.

[0067] In this embodiment, the plate body 20 is a circular plate-shaped structure, and the plate body 20 is suitable for being set in the installation cavity 104. At this time, the plate body 20 and the inflow hole 111 are suitable for being set on opposite sides of the expansion cavity 103, and the axis of the plate body 20 and the axis of the inflow hole 111 are located in the same straight line. At the same time, a plurality of diversion holes 201 are provided on the plate body 20, and the plurality of diversion holes 201 are arranged around the axis of the plate body 20 as the center. By limiting the axis of the plate body 20 and the axis of the inflow hole 111 to be located in the same straight line, and coordinating with the structure of the expansion cavity 103, it can be further ensured that the refrigerant can flow evenly to each diversion hole 201, thereby achieving the effect of refrigerant diversion and ensuring the sameness of the refrigerant.

[0068] It should be noted that, in this embodiment, the housing 10 can be manufactured by spinning, coil welding, or stamping at both ends. Meanwhile, the plate 20 is fixed in the mounting cavity 104 of the housing 10 by welding.

[0069] Furthermore, in this embodiment, the housing 10 includes a main body (not shown) and a mounting portion. The main body defines an expansion chamber 103 for diverting and mixing the refrigerant. The mounting portion 12 is located on one side of the main body and is used to mount the plate 20 or other components described below. The mounting portion 12 defines a mounting chamber 104 within the mounting chamber 104, the aperture of which is the same as the maximum inner diameter of the expansion chamber 103.

[0070] Furthermore, the side of the plate 20 facing away from the expansion cavity 103 is the top surface, i.e., the aforementioned mounting surface. Optionally, the mounting surface and the top end surface of the housing 10 are coplanar. Alternatively, the mounting surface is parallel to the top end surface of the housing 10, and the plate 20 is housed within the mounting cavity 104. In this case, a welding space is defined between the mounting surface and the top end of the housing 10 to accommodate the first flange 210 of the first connecting tube 200, thereby ensuring a secure weld between the first connecting tube 200 and the plate 20.

[0071] In addition, the structure of the shell 10 may be configured as other shapes, such as a square tube, in addition to the aforementioned circular tube structure, so as to ensure that the expansion chamber 103 and the plate 20 are mounted and fixed.

[0072] Furthermore, the diverter assembly 1000 also includes a diverter cone 30 , which is disposed on the plate body 20 . The axis of the diverter cone 30 is co-linear with the axis of the inflow hole 111 and is used to guide the fluid from the inflow hole 111 to the diverter hole 201 .

[0073] Specifically, by providing the diverter cone 30, a diversion surface can be formed in the diverter cavity, so that after entering the expansion cavity 103, the refrigerant can flow evenly to each diverter hole 201 under the action of the diverter cone 30, thereby ensuring the diverting effect of the diverter assembly 1000. At the same time, the provision of the diverter cone 30 can also cooperate with the structure of the expansion cavity 103 to further improve the diverting effect of the distributor 100.

[0074] It is important to understand that if Figure 2 、 Figure 3 、 Figure 5 and Figure 6As shown, a diverter cone 30 is provided on the plate body 20, and the cone line of the diverter cone 30 is located in the same straight line as the axis of the inflow hole 111, and at this time, a plurality of diverter holes 201 are arranged at intervals along the circumference of the diverter cone 30, and are arranged at intervals from the diverter cone 30. In this embodiment, the diverter cone 30 has a small diameter end and a large diameter end, wherein the large diameter end is connected to the plate body 20. Optionally, the small diameter end is provided in the expansion cavity 103 and is provided corresponding to the inflow hole 111. At this time, the refrigerant entering the expansion cavity 103 from the inflow hole 111 will impact the small diameter end of the diverter cone 30, and under the action of the cone surface of the diverter cone 30, it will flow to each diverter hole 201, which helps to ensure the uniformity and rapidity of the refrigerant flow.

[0075] It should be noted that, in addition to placing the small-diameter end in the expansion chamber 103, the small-diameter end can also be placed on the side away from the expansion chamber 103, that is, the small-diameter end is placed inside the installation chamber 104. In this case, the internal hollowing of the diverter cone 30 forms a conical flow guide space. The refrigerant entering the expansion chamber 103 from the inflow hole 111 will impact the small-diameter end of the diverter cone 30 and, under the action of the conical surface of the diverter cone 30, flow to each diverter hole 201. Since the inflow hole 111 and the small-diameter end are located on the same straight line, the diversion space is on the same horizontal plane, and the pressure at each location is the same or similar, which helps to ensure the uniformity of the refrigerant flow.

[0076] It should be further understood that the diverter cone 30 and the plate body 20 are integrally formed. By providing the diverter cone 30 and the plate body 20 as an integrally formed part, it helps to reduce the difficulty of manufacturing and assembling the distributor 100. Figure 5 As shown, in this embodiment, the diverter cone 30 and the plate body 20 are integrally stamped. This provides a simple structure and facilitates fabrication. Optionally, the diverter cone 30 may be hollowed out to reduce the manufacturing cost of the distributor 100 while ensuring the diversion effect of the diverter cone 30.

[0077] In some other embodiments of the present application, the diverter cone 30 and the plate body 20 are split structures. Specifically, a avoidance hole 203 is opened in the middle of the plate body 20, the diverter cone 30 is arranged in the avoidance hole 203, and the small diameter end of the diverter cone 30 is located in the expansion cavity 103. The diverter cone 30 is set in the avoidance hole 203 of the plate body 20, and the diverter cone 30 and the plate body 20 are welded and fixed. Such a setting, on the one hand, helps to adjust the insertion depth of the diverter cone 30, ensure the distance between the diverter cone 30 and the inflow hole 111, helps to improve the applicability of the distributor 100, and adjust the diversion effect. On the other hand, the diverter cone 30 can be set to different structures such as a cone, a triangular pyramid, a square pyramid, a pentagonal pyramid, etc. to adapt to the number of diverter holes 201 and ensure the diversion effect. At the same time, it helps to improve the diversity of the diverter cone 30, thereby improving the applicability of the distributor 100.

[0078] It is important to understand that if Figure 6 As shown, the diverter cone 30 includes a cone 31, an extension section 32, and a second flange 33. The cone 31, extension section 32, and second flange 33 are sequentially connected from the inflow hole 111 toward the plate body 20. The extension section 32 mates with the inner wall of the avoidance hole 203. Optionally, the cone 31 is disposed within the expansion cavity 103, and the second flange 33 is in close contact with the side of the plate body 20 facing away from the expansion cavity 103. The provision of the extension section 32, which can be mated with the avoidance hole 203, facilitates achieving a sealed connection between the plate body 20 and the diverter cone 30. At the same time, the provision of the second flange 33, on the one hand, helps to further improve the sealing effect between the plate body 20 and the diverter cone 30; on the other hand, it can also improve the assembly efficiency of the plate body 20 and the diverter cone 30, thereby improving the assembly effect of the distributor 100; thirdly, the second flange 33 can increase the welding area between the diverter cone 30 and the plate body 20, which helps to further improve the connection effect between the diverter cone 30 and the plate body 20.

[0079] It should be pointed out that when the cone of the diverter cone 30 is set in the installation cavity 104, the second flange 33 is fitly connected to the side of the plate body 20 facing the expansion cavity 103. At this time, the welding position of the diverter cone 30 and the plate body 20 is the connection between the cone and the plate body 20. Such a setting helps to reduce the impact of welding on the flow of refrigerant, so as to ensure the effect of the diverter cone 30.

[0080] Alternatively, the diverter cone 30 can be composed solely of the cone 31 and the extension 32. In this case, the end surface of the extension 32 facing away from the cone 31 can optionally be coplanar with the mounting surface to facilitate welding. Alternatively, the end surface of the extension 32 facing away from the cone 31 can be parallel to the mounting surface, with the extension 32 extending outward to the side of the plate 20 facing away from the expansion cavity 103, or positioned within the avoidance hole 203.

[0081] Furthermore, the first connecting tube 200 is a rigid member. Specifically, by defining the first connecting tube 200 as a rigid member, it is helpful to realize the automated welding of the first connecting tube 200 and the plate body 20. It also helps to realize the processing and production of the first flange 210 and ensure the structural strength of the first connecting tube 200. Because multiple first connecting tubes 200 can be connected to multiple connection ports of the first heat exchanger 2000 respectively, it is helpful to realize the automated welding of the first connecting tubes 200 and the first connecting tubes 200, thereby helping to prevent the problem of the first connecting tube 200 rebounding after connection.

[0082] It is important to understand that if Figures 2 to 4As shown, the first connecting tube 200 includes a tube body 220 and a first flange 210. In this embodiment, the tube body 220 is a rigid member and extends along a unique preset path, that is, multiple first connecting tubes 200 are respectively extended along different preset paths. A first flange 210 is provided at one end of the tube body 220, and a first adapter 60 is provided at the other end of the tube body 220. The first flange 210 and the tube body 220 are integrally formed, and the first adapter 60 is detachably connected to the tube body 220. By configuring the tube body 220 as a rigid member, it helps prevent the first connecting tube 200 from rebounding after being plugged into the heat exchanger. In addition, the overall structure of the first connecting tube 200 is simple, easy to process and form, and low in processing cost. The external dimensions of the distributor 100 can be reduced, the structural space requirement is small, design space is saved, and a lightweight design is achieved.

[0083] In this embodiment, the first adapter 60 is inserted into the first connecting tube 200 and is adapted to connect to the connection port of the first heater. Connection methods include, but are not limited to, screw connection, clamping connection, snap connection, riveting, bonding, welding, etc. Optionally, the first adapter 60 is fixed to the connection port by welding.

[0084] It should be noted that the material of the first adapter 60 is the same as that of the connecting port, which helps improve the connection between the first connector and the connecting port, thereby ensuring the stability of the connection. The material of the first adapter 60 and the first connecting tube 200 can be the same or different, and no further restrictions are imposed here. Optionally, the first adapter 60 is made of brass, stainless steel, etc.

[0085] Furthermore, the aperture of the diverter hole 201 is smaller than the inner diameter of the first connecting tube 200. Specifically, by limiting the aperture of the diverter hole 201 to be smaller than the inner diameter of the first connecting tube 200, the refrigerant can change its flow direction due to the increase in flow space after entering the first connecting tube 200, thereby helping to improve the mixing effect of the refrigerant. Optionally, the aperture of the diverter hole 201 is 0.4 to 0.8 times the inner diameter of the first connecting tube 200. Optionally, the aperture of the diverter hole 201 is 0.5 times the inner diameter of the first connecting tube 200. And because the diverter hole 201 is concentrically arranged with the first connecting tube 200, the flow of the refrigerant can be made more uniform, and a better mixing effect can be ensured.

[0086] Furthermore, the distributor 100 has a first inserting portion 11 , which defines an inflow hole 111 . Meanwhile, the flow diversion assembly 1000 further includes a second connecting pipe 300 , which is sleeved on the outside of the first inserting portion 11 .

[0087] Specifically, by providing the first inserting portion 11 on the distributor 100 so as to be plug-connected with the second connecting pipe 300 , it helps to reduce the difficulty of assembling the diverter assembly 1000 and improve the assembly efficiency of the diverter assembly 1000 .

[0088] It is important to understand that if Figures 1-6 As shown, the bottom of the distributor 100 protrudes outward and is formed with a first plug-in portion 11. The interior of the first plug-in portion 11 defines an inflow hole 111. At the same time, the second connecting pipe 300 is sleeved on the outside of the first plug-in portion 11. In this embodiment, the second connecting pipe 300 includes an inlet pipe 301. The interior of the inlet pipe 301 defines a cavity, which includes an incident cavity 101 and a connecting cavity (not shown in the figure). The incident cavity 101 is used for the inflow of refrigerant, and the connecting cavity is sleeved on the outside of the first plug-in portion 11 so that the refrigerant flowing through the incident cavity 101 enters the expansion cavity 103 through the inflow hole 111.

[0089] In this embodiment, the inner diameter of the incident cavity 101 is larger than the inner diameter of the connecting cavity. At the same time, a transition cavity (not shown in the figure) is provided between the incident cavity 101 and the connecting cavity to ensure that the refrigerant can enter the inflow hole 111. At this time, along the flow path of the refrigerant, the inlet pipe 301 cooperates with the shell 10 to form the incident cavity 101, the steady flow cavity 102 (inflow hole 111), and the expansion cavity 103 connected in sequence. By limiting the inner diameters of the incident cavity 101, the steady flow cavity 102, and the expansion cavity 103, the inlet pipe 301 cooperates with the shell 10 to form a Venturi tube structure, so as to increase the flow rate by reducing the flow area, thereby generating a low-pressure area in the throat. The change in the refrigerant flow rate helps to further improve the refrigerant mixing effect and increase the flow rate of the refrigerant flowing to each diversion hole 201, thereby ensuring the diversion effect of the diversion component 1000.

[0090] It should be noted that, in addition to inserting the inlet tube 301 onto the outside of the first inserting portion 11, the end of the inlet tube 301 closest to the expansion chamber 103 can also be inserted into the interior of the inflow hole 111. Of course, in addition to this insertion method, other methods such as threaded connection, flange connection, and welding can also be used. Optionally, multiple welds can be provided at the connection between the inlet tube 301 and the first inserting portion 11 to further enhance the connection between the inlet tube 301 and the first inserting portion 11.

[0091] In addition, the inlet pipe 301 and the housing 10 can be configured as an integrally formed part. This configuration helps to improve the structural strength of the diverter assembly 1000 and improve the assembly efficiency of the diverter assembly 1000.

[0092] Furthermore, the second connecting tube 300 also includes an inlet tube 301 and a second adapter 70. The inlet tube 301 is sleeved onto the first inserting portion 11 and has an inlet cavity 101. The inner diameter of the inlet cavity 101 is larger than the inner diameter of the inlet hole 111. The second adapter 70 is inserted into the end of the inlet tube 301 facing away from the inlet hole 111.

[0093] Specifically, by providing the inlet pipe 301, the flow-dividing assembly 1000 can form a Venturi tube structure at the connection between the second connecting pipe 300 and the housing 10, thereby increasing the flow rate of the refrigerant after entering the distributor 100 from the second connecting pipe 300, and cooperating with the diverter cone 30 to improve the diversion and mixing effects of the refrigerant. At the same time, the provision of the second adapter 70 enables the inlet pipe 301 to communicate with other connecting structures, and by changing the material of the second adapter 70, the inlet pipe 301 and the other connecting structures can be plugged in and fixed by welding. There is a need to improve the applicability of the inlet pipe 301, and thus improve the applicability of the flow-dividing assembly 1000.

[0094] It should be understood that the second connecting pipe 300 includes an inlet pipe 301 and an incoming flow pipe (not shown in the figure). In this embodiment, the inlet pipe 301 and the incoming flow pipe are connected by a second adapter 70. The second adapter 70 is inserted into the inlet pipe 301, and the second adapter 70 and the inlet pipe 301 are made of the same material. By providing a welding point at the connection between the second adapter 70 and the inlet pipe 301, the connection effect between the second adapter 70 and the inlet pipe 301 can be further improved. The inlet pipe 301 is provided so that it can cooperate with the shell 10 to form a venturi tube structure, and the provision of the second adapter 70 can further improve the applicability of the diverter assembly 1000, so that the inlet pipe 301 and the incoming flow pipe have a better connection effect, thereby ensuring the stability of the transmission of the refrigerant and the service life of the diverter assembly 1000.

[0095] It should be pointed out that in addition to the above-mentioned connection method, the incoming flow pipe and the inlet pipe 301 can be directly connected. Optionally, the incoming flow pipe is screwed onto the outer peripheral surface of the inlet pipe 301, or the incoming flow pipe and the inlet pipe 301 are made of the same material so that the incoming flow pipe and the inlet pipe 301 can be welded and fixed, or the incoming flow pipe is inserted into the inside of the inlet pipe 301.

[0096] The second aspect of this practical method also proposes a HVAC equipment 1, which includes a first heat exchanger 2000, a second heat exchanger 3000 and a diversion component 1000. The diversion component 1000 is the above-mentioned diversion component 1000, and at this time, the first connecting pipe 200 is connected to the first heat exchanger 2000, and the distributor 100 is connected to the second heat exchanger 3000.

[0097] Compared with the prior art, the HVAC equipment 1 proposed in the present invention has the technical advantages possessed by the above-mentioned diversion component 1000, which will not be described in detail here.

[0098] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
