Specific embodiments

[0072] In order to make the objectives, features, and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0073] Please refer to Figures 1 to 8 As shown in the figure, this embodiment provides a cabinet air conditioner that is easy to produce and assemble, including:

[0074] The middle frame structure 300 is integrally formed as a whole. The middle frame structure 300 includes a frame body 301, a partition plate 302, a plurality of brackets 303 for installing the components of the cabinet air conditioner, and a drainage channel 304 for discharging condensed water. The partition plate 302 divides the internal space of the frame body 301 into an evaporation chamber 310 and a condensation chamber 311;

[0075] The first panel 203 is detachably connected to one side of the frame body 301 close to the evaporation chamber 310;

[0076] The second panel 204 is detachably connected to one side of the frame body 301 close to the condensation chamber 311;

[0077] The components of the cabinet air conditioner include an outdoor fan 404, a condenser 403, a compressor 405 located in the condensation chamber 310, and an indoor fan 402 and an evaporator 401 located in the evaporation chamber 310.

[0078] The frame body 301, the partition plate 302, a plurality of brackets 303 for installing the components of the cabinet air conditioner, and the drainage channel 304 for discharging condensed water are integrated through the integrally formed middle frame structure 300. The partition plate 302 divides the internal space of the frame body 301 into an evaporation chamber 310 and a condensation chamber 311. When producing and assembling the cabinet air conditioner, only the middle frame structure 300 needs to be injection-molded, and then the components of the cabinet air conditioner are installed on the plurality of brackets 303, and the electrical connection and pipeline connection between the components of the cabinet air conditioner are completed, etc. Finally, the first panel 203 and the second panel 204 are installed on the middle frame structure 300 to complete the production and assembly.

[0079] A cabinet air conditioner that is easy to produce and assemble provided by an embodiment of the present invention reduces the connection process between the frame body 301 and the partition plate 302, reduces the assembly processes of producing and assembling the drainage channel 304 and installing the plurality of brackets 303, greatly simplifies the production process and assembly process of the cabinet air conditioner, and improves the production efficiency. Moreover, the middle frame structure 300 is integrally formed as a whole, preventing water from entering the body, having a better waterproof effect. The injection-molded middle frame structure 300 is not only lighter in weight, convenient for handling and installation, but also has a better heat preservation and heat insulation effect.

[0080] It should be noted that both the first panel 203 and the second panel 204 can be made by injection molding or made of sheet metal parts.

[0081] Specifically, the middle frame structure 300 is integrally formed by microcellular injection molding, which has the advantages of seamless appearance and good waterproof performance, and the microcellular injection molded parts have good heat preservation and heat insulation effects and are light in weight, facilitating handling and installation.

[0082] In the prior art, when assembling and producing a cabinet air conditioner, it is usually necessary to install a drainage channel 304 for discharging condensed water and a plurality of brackets 303 for fixing the components of the cabinet air conditioner on a partition plate 302. However, with the middle frame structure 300 provided in this embodiment, the drainage channel 304 and the plurality of brackets 303 can be integrally injection-molded simultaneously when the middle frame structure 300 is integrally formed, thereby simplifying the production process and assembly procedures and improving production efficiency.

[0083] In another embodiment of the present application, in order to enable the middle frame structure 300 to integrate more functions, reduce the assembly procedures, and improve the temperature regulation performance of the cabinet air conditioner having the middle frame structure 300, the integrally formed middle frame structure 300 further includes an air distribution component 305, and a plurality of such air distribution components 305 are respectively provided on both sides of the partition plate 302. The air distribution component 305 is used to improve the air flow distribution in the evaporation chamber 310 and the condensation chamber 311, and improve the temperature field distribution of the air in the evaporation chamber 310 and the condensation chamber 311. The air distribution component 305 includes a wind guiding fin 3051 and a vortex generator 3052. The wind guiding fin 3051 is used to guide the air flow distribution, so that the air distribution component 305 has a function of dividing the air flow, and the vortex generator 3052 is used to generate vortex mixing of the air flow, so that the air distribution component 305 has a function of mixing the air flow. Through air distribution and air mixing, the air flow organization in the evaporation chamber 310 and the condensation chamber 311 can be optimized, the air field uniformity can be increased, and the heat exchange effect of the evaporator 401 and the condenser 403 can be improved, thereby improving the temperature regulation ability of the cabinet air conditioner.

[0084] As an optional manner of this embodiment, the plurality of air distribution components 305 on both sides of the partition plate 302 are all arranged in an adjacent row offset form, as Figure 7 shown, this setting can improve the air distribution ability.

[0085] In another embodiment of the present application, the drainage channel 304 includes a water receiving tray 3041 and a sewer 3042. The water receiving tray 3041 is generally arranged at the middle position of the frame body 301, specifically at the bottom position of the partition plate 302, so as to divide the internal space of the frame body 301 into an evaporation chamber 310 and a condensation chamber 311 through the partition plate 302 and the water receiving tray 3041 together. The sewer 3042 is arranged in the condensation chamber 311. The water receiving tray 3041 is used to receive the dripping condensed water, and the sewer 3042 is connected to the water outlet of the water receiving tray 3041. A drainage hole is provided at the bottom of the frame body 301 for the sewer 3042 to discharge the condensed water.

[0086] Furthermore, the evaporation chamber 310 and the condensation chamber 311 are separately and independently separated to achieve heat insulation, preventing the heat dissipated during the operation of the compressor 405 from entering the evaporation chamber 310, and as much as possible avoiding the influence of this heat on the temperature of the air in the evaporation chamber 310, and ensuring the heat exchange efficiency of the evaporator 401 in the evaporation chamber 310.

[0087] Further, the multiple brackets 303 include: an indoor fan mounting bracket 3031 located in the evaporation chamber 310; an electric control box mounting bracket 3032 located in the evaporation chamber 310; a compressor mounting bracket 3033 located in the condensation chamber 311; and an outdoor fan mounting bracket 3034 located in the condensation chamber 311. The electric control box 410 generally includes essential electrical components required to control the operation of the cabinet air conditioner. The essential electrical components include a circuit breaker, a terminal block, a controller, etc. The electric control box 410 adopts a fully metal-sealed electric control box to prevent short circuits of the electric control components from causing fires. Specifically, the cabinet air conditioner is further provided with an indoor fan auxiliary mounting plate 412 and an outdoor fan auxiliary mounting plate 413. The indoor fan 402 is installed on the indoor fan mounting bracket 3031 through the indoor fan auxiliary mounting plate 412, and the outdoor fan 404 is installed on the outdoor fan mounting bracket 3034 through the outdoor fan auxiliary mounting plate 413.

[0088] In another embodiment of the present application, in order to further improve the production and assembly efficiency and simplify the production and assembly process, the integrally formed middle frame structure 300 further includes a flange 308. The flange 308 is arranged along the peripheral wall of the frame body 301, and the flange 308 is used to connect the electrical control cabinet. Specifically, an opening for installing the cabinet air conditioner is provided on the electrical control cabinet, and flange mounting holes are provided at the edge of the opening. The flange 308 is fixedly connected to the flange mounting holes through bolts. Therefore, for the cabinet air conditioner provided in this embodiment, the flange 308 can be used to more conveniently fix and install the cabinet air conditioner on the electrical control cabinet.

[0089] Further, as an optional way of this embodiment, the integrally formed middle frame structure 300 further includes a handle 309. A handle 309 is provided on each side of the frame body 301. Through this handle 309, it is convenient to carry the middle frame structure 300 and the cabinet air conditioner, and it is also convenient to install the cabinet air conditioner on the electrical control cabinet.

[0090] In another embodiment of the present application, the integrally formed middle frame structure 300 further includes a fresh air channel 306. The fresh air channel 306 is located in the condensation chamber 311, and the internal space of the fresh air channel 306 is isolated from the condensation chamber 311, which can prevent the condensation chamber 311 from affecting the air temperature in the fresh air channel 306. The two ends of the fresh air channel 306 are respectively communicated with the outside atmosphere and the air in the electrical control cabinet. The fresh air channel 306 has two functions: the first is for emergency use. When the cabinet air conditioner fails, air is directly inhaled from the outside atmosphere into the electrical control cabinet to prevent the air temperature in the electrical control cabinet from getting out of control; the second is for energy saving. When the outside atmospheric temperature is relatively low, such as in winter, fresh air can be directly introduced to cool the electrical control cabinet, and the compressor 405, the indoor fan 402, the outdoor fan 404, etc. can be stopped, so as to achieve the purpose of energy saving.

[0091] Further, a fresh air fan installation station 3061 for installing the fresh air fan 406 needs to be provided in the fresh air passage 306 to introduce fresh air by means of the fresh air fan 406.

[0092] Further, when there is no exhaust function in the electrical control cabinet, in order to prevent the air pressure in the electrical control cabinet from being too high, an exhaust function needs to be added to relieve the pressure of the electrical control cabinet. Specifically, an exhaust fan installation station 307 for installing the exhaust fan 408 is provided in the condensation chamber 311. Since only exhaust is involved, there is no need to add an independent exhaust passage, and the condensation chamber 311 can be directly used as the exhaust passage, which not only simplifies the middle frame structure but also makes rational use of the entire space. During exhaust, the air in the electrical control cabinet directly enters the condensation chamber 311 and then is discharged to the outside atmosphere through the air outlet of the condensation chamber 311.

[0093] As an alternative in this embodiment, the exhaust fan 408 is located above the fresh air fan 406, and the exhaust fan 408 and the fresh air fan 406 are arranged in a vertical offset manner, which can prevent the exhaust fan 408 and the fresh air fan 406 from interfering with each other, enhance the air flow circulation, and improve the efficiency of introducing fresh air and exhaust.

[0094] In this embodiment, the partition 302 and the water receiving tray 3041 together divide the cabinet body 301 into an evaporation chamber 310 and a condensation chamber 311. The outdoor fan 404, the compressor 405, the condenser 403, the fresh air fan 406, and the exhaust fan 408 are arranged in the condensation chamber 311, and the indoor fan 402 and the evaporator 401 are arranged in the evaporation chamber 310. The fresh air passage 306 is isolated from the condensation chamber 311, and the air outlet of the condensation chamber 311 is used as the exhaust passage. With the above structural layout, the cabinet air conditioner provided in this embodiment not only has a fresh air function but also has a more reasonable overall layout, saves space, and simplifies the product structure.

[0095] In another embodiment of the present application, a fresh air damper 407 is provided in the fresh air passage 306, and an exhaust damper 409 is provided in the condensation chamber 311. Both the fresh air damper 407 and the exhaust damper 409 are gravity dampers. The characteristic of a gravity damper is that only under the influence of a wind force with a positive pressure, and the wind force can overcome the self-gravity or spring tension of the damper, will the damper open; otherwise, the damper will close under the action of its self-gravity or spring tension. A gravity damper only allows wind in one direction to pass through, and wind in the opposite direction cannot pass through. The positive pressure can be understood as that the wind in the allowed passing direction has a positive pressure, and the wind in the opposite direction has a negative pressure.

[0096] When the fresh air fan 406 is not turned on, the fresh air damper 407 is not affected by the wind force and is not affected by the air volume of the positive pressure. The fresh air damper 407 will automatically close under the action of gravity to prevent dust and rainwater in the outside air from entering the electrical control cabinet. When the fresh air fan 406 is turned on, the fresh air damper 407 is affected by the wind force of the positive pressure, and the fresh air damper 407 is opened by the wind force overcoming the gravity, so that the outside air enters the fresh air channel 306. Of course, in order to prevent dust and rainwater in the outside air from entering the electrical control cabinet, when there is a lot of dust or rainwater in the outside air, the fresh air fan 406 can also be prohibited from starting. When the exhaust fan 408 is not turned on, the exhaust damper 409 is not affected by the wind force and is not affected by the air volume of the positive pressure. The exhaust damper 409 will automatically close under the action of gravity, and the airflow generated when the outdoor fan 404 works will generate a reverse pressure on the exhaust damper 409, thereby effectively isolating the electrical control cabinet from the outside, so as to prevent dust and rainwater in the outside air from entering the electrical control cabinet through the condensation chamber 311. When the exhaust fan 408 is turned on, the exhaust damper 409 is affected by the wind force of the positive pressure, and the exhaust damper 409 is opened by the wind force overcoming the gravity, so that the air in the electrical control cabinet is discharged out of the cabinet through the condensation chamber 311 from the second air outlet 2044.

[0097] As an alternative in this embodiment, the fresh air damper 407 and the exhaust damper 409 can also be selected as electric dampers. The fresh air fan 406 and the exhaust fan 408 can be selected as axial fans.

[0098] In order to further prevent dust in the outside air from entering the electrical control cabinet, a filter screen is provided downstream of the fresh air channel 306. Dust larger than a specified value is filtered through the filter screen to ensure the air cleanliness in the electrical control cabinet. In order to facilitate the disassembly, washing and other maintenance operations of the filter screen, the filter screen is arranged at the first fresh air outlet 2035 of the first panel 203 and is located outside the cabinet air conditioner.

[0099] In another embodiment of the present application, the first panel 203 is provided with a first air inlet 2033, a first air outlet 2034, a first fresh air outlet 2035, a first exhaust outlet 2036 and a display panel assembly 411, and the second panel 204 is provided with a second air inlet 2043, a second air outlet 2044 and a second fresh air outlet 2045. When the electrical control cabinet exhausts air, the air flow is discharged to the outside atmosphere through the first exhaust outlet 2036, the condensation chamber 311 and the second air outlet 2044 in sequence.

[0100] Further, refer to Figures 9 to 13 , a wind inlet grille 20 for improving the air inlet efficiency is respectively provided at the first air inlet 2033 and the second air inlet 2043. Specifically, the air flow direction is Figure 11flows from the right side to the left side in it, and the air flow passing through is cut and sorted by the air inlet grille 20, so that the air flow passes through the air inlet smoothly and orderly, thereby improving the air inlet efficiency and reducing noise.

[0101] Specifically, the air inlet grille 20 includes a guide ring 201 and a plurality of air inlet stationary vanes 202. The incoming air flow first passes through the air inlet stationary vanes 202, and the air inlet stationary vanes 202 cut, shape and sort the air flow, thereby reducing the turbulent flow existing in the incoming air flow and improving the air inlet quality. Then, the shaped incoming air flow passes through the guide ring 201, and the guide ring 201 guides the incoming air flow, thereby improving the air inlet efficiency and reducing the air inlet noise.

[0102] Specifically, the guide ring 201 includes an assembly ring 2018 and a guide portion 2019. The assembly ring 2018 is used to fix the air inlet grille 20 on the first panel 203. The assembly ring 2018 is connected to the guide portion 2019, and the guide portion 2019 is a ring structure. Therefore, the guide portion 2019 and the assembly ring 2018 jointly form an air flow channel. The plurality of air inlet stationary vanes 202 are arranged in an arc-shaped line, a central radial line or an S-shaped line, and a ventilation slot corresponding to the line (arc-shaped line, central radial line or S-shaped line) is formed between adjacent air inlet stationary vanes 202. Therefore, when the fan sucks air, a spiral air flow corresponding to the line can be formed through the ventilation slot. The spiral air flow has a cut-in angle, which is easy to push the air flow forward, making the air inlet smoother and effectively reducing the air inlet noise.

[0103] Therefore, the air inlet grille 20 provided in this embodiment can improve the air inlet efficiency and air circulation efficiency of the cabinet air conditioner and reduce the noise generated by turbulent flow through the guide ring 201 and the plurality of air inlet stationary vanes 202.

[0104] In another embodiment of the present application, the assembly ring 2018 includes a first assembly plate 2011 and a second assembly plate 2012, and the first assembly plate 2011 is connected to the second assembly plate 2012. An annular plate 2031 is provided on the first panel, and the second assembly plate 2012 is provided with a buckle 2013 that cooperates with the first assembly plate 2011 and is used to clamp the annular plate 2031. When installing and fixing the air inlet grille 20, the first assembly plate 2011 is attached to one side of the annular plate 2031, and the buckle 2013 passes through the air inlet and is buckled on the other side of the annular plate 2031, so that the annular plate 2031 is clamped and fixed by the buckle 2013 and the first assembly plate 2011.

[0105] Furthermore, the buckle 2013 can be a spring-type buckle equipped with a spring, or a buckle made of an elastic material. In this embodiment, the latter is selected to facilitate the integral molding of the air inlet grille 20.

[0106] Since the annular plate 2031 is only clamped and fixed by the buckle 2013 and the first assembly plate 2011, the air inlet grille 20 is prone to rotational displacement. Therefore, in another embodiment of the present application, a limiting block 2014 is further provided on the second assembly plate 2012 beside the buckle 2013, and a limiting groove 2032 is also provided on the annular plate 2031. When installing and fixing the air inlet grille 20, the limiting block 2014 is snapped into the limiting groove 2032, thereby restricting the rotation of the air inlet grille 20. As an alternative in this embodiment, the number of the limiting blocks 2014 is six, and the number of the limiting grooves 2032 is six. In this embodiment, by restricting the rotation of the air inlet grille 20 and combining with the clamping and fixing of the air inlet grille 20 by the buckle 2013, the air inlet grille 20 can be installed and fixed more firmly. Further, a guiding inclined surface 2015 is provided at one end of the limiting block 2014 away from the center of the guiding ring 201, for guiding the limiting groove 2032, so as to facilitate the smooth sliding sleeve of the limiting groove 2032 on the limiting block 2014.

[0107] In another embodiment of the present application, the guiding part 2019 includes a first guiding plate 2016 and a second guiding plate 2017. The first guiding plate 2016 and the second guiding plate 2017 are connected, and the air inlet stationary vane 202 is connected to the first guiding plate 2016. Among them, the main guiding function is performed by the first guiding plate 2016. The opening of the first guiding plate 2016 gradually shrinks in the direction away from the air inlet stationary vane 202, so as to achieve the guiding effect. As an alternative, the first guiding plate 2016 is a conical ring body, and its opening is in a trumpet shape. Further, the connection between the first guiding plate 2016 and the second guiding plate 2017 is a smooth transition connection, which can make the air flow guided by the first guiding plate 2016 pass through the second guiding plate 2017 more smoothly. The air inlet grille 20 is an integrally formed structure, which can reduce the assembly process of the air inlet grille 20. As an alternative, the air inlet grille 20 is made of polypropylene PP material.

[0108] In another embodiment of the present application, please refer to Figures 14 to 19 As shown, the cabinet air conditioner provided in this embodiment further includes a foot fixing device 100 for fixing the feet of the compressor 405.

[0109] The foot fixing device 100 includes a positioning rod 103 and an elastic buckle cap 101. The installation and fixing of the feet are achieved by the snap connection of the buckle cap 101 and the positioning rod 103. The main advantage of this foot fixing device 100 is easy installation, which makes the installation efficiency higher. During installation, the foot is sleeved on the positioning rod 103, and then the buckle cap 101 is elastically snapped onto the outer wall of the positioning rod 103, and the foot is tightly fixed by the pressing part 1016 of the buckle cap 101, so as to achieve the installation and fixing of the equipment.

[0110] Since the compressor 405 generates large vibrations during operation, when the vibration amplitude is too large, the foot fixing device 100 may be damaged or other safety accidents may occur. Therefore, to avoid this situation, the foot fixing device 100 further includes an elastic shock pad 102, and an annular mounting groove is provided on the outer peripheral wall of the shock pad 102. During installation, the positioning rod 103 is first fixed to the bottom of the middle frame structure 300, then the shock pad 102 is sleeved on the positioning rod 103, then the foot is sleeved in the annular mounting groove of the shock pad 102, and finally the buckle cap 101 is snap-fitted on the positioning rod 103 to compress the shock pad 102, so as to firmly compress and fix the foot by the annular mounting groove of the shock pad 102. The foot fixing device 100 can reduce the vibration amplitude during equipment operation through the shock pad 102, and avoid damage to the foot fixing device 100 or other safety accidents caused by too large vibration amplitude.

[0111] Further, the positioning rod 103 includes a first rod section 1031, a second rod section 1032 and a third rod section 1033. An annular groove 1034 is provided between the first rod section 1031 and the second rod section 1032, and a first guiding slope 1035 is provided on the second rod section 1032. The buckle cap 101 is provided with a through hole 1010, and the through hole 1010 includes a first hole section 1011, a second hole section 1012 and a third hole section 1013.

[0112] A protrusion 1014 is provided on the inner wall of the first hole section 1011. When the buckle cap 101 is sleeved on the positioning rod 103 through the through hole 1010, by the elasticity of the buckle cap 101, the protrusion 1014 is snapped into the annular groove 1034 through the first guiding slope 1035. At this time, the pressing part 1016 at the bottom of the buckle cap 101 tightly presses on the foot. To make the protrusion 1014 snap into the annular groove 1034 more smoothly, a second guiding slope 1019 is further provided at the bottom of the protrusion 1014.

[0113] Further, the second hole section 1012 is used to accommodate the second rod section 1032, a limiting block 1015 is provided on the inner wall of the third hole section 1013, the limiting block 1015 abuts against the outer wall of the third rod section 1033, and a limiting slope 1020 for abutting against the first guiding slope 1035 is further provided at the bottom of the limiting block 1015. Therefore, when the protrusion 1014 is snapped at the annular groove 1034, by the limiting slope 1020 abutting against the first guiding slope 1035, when there is no external force, the protrusion 1014 is restricted at the position of the annular groove 1034, so that the pressing part 1016 firmly presses the foot.

[0114] It should be noted that the first guiding inclined surface 1035 can be a plane with an inclination angle or an arc-shaped curved surface, as long as it can facilitate the convex 1014 to be snapped into the annular groove 1034. The shape of the limiting inclined surface 1020 should match the shape of the first guiding inclined surface 1035 so that the two inclined surfaces can contact and abut against each other to limit the convex 1014 to be snapped in the annular groove 1034.

[0115] Since the convex 1014 is elastically snapped into the annular groove 1034 by using the snap cap 101, in order to further make the convex 1014 snap into the annular groove 1034 more smoothly, three opening grooves 1017 are provided on the snap cap 101, and the opening grooves 1017 are also provided with arc-shaped connecting parts 1018. When it is necessary to snap the convex 1014 into the annular groove 1034, the elasticity of the snap cap 101 is used to expand the opening of the first hole section 1011. Since there are three opening grooves 1017, the deformation space of the snap cap 101 is larger, so that the first hole section 1011 can open a larger opening, enabling the convex to be more conveniently snapped with the annular groove 1034. Among them, the function of the arc-shaped connecting part 1018 is to prevent the opening of the first hole section 1018 from being too large (when the opening is expanded, the arc-shaped connecting part 1018 is slowly stretched into a straight line) to avoid the convex 1014 from disengaging from the annular groove 1034.

[0116] In this embodiment, when the number of the opening grooves 1017 is three, the number of the convexes 1014 is three, and the number of the limiting blocks 1015 is three. The numbers of the opening grooves 1017, the convexes 1014, and the limiting blocks 1015 can all be freely set according to needs.

[0117] Furthermore, the positioning rod 103 is fixed on the middle frame structure 300, for example, by integrally forming on the middle frame structure 300 or by welding to be fixed on the middle frame structure 300. The positioning rod 103 can also be fixed on the middle frame structure 300 by fixing screws. In this embodiment, a fixing seat 1036 is provided at the bottom of the positioning rod 103, and a fixing hole 1037 and a positioning groove 1038 are provided on the fixing seat 1036. The fixing seat 1036 is fixed on the middle frame structure 300 by installing fixing screws through the fixing hole 1037. Furthermore, the integrally formed middle frame structure 300 also includes a positioning block. When it is necessary to fix the positioning rod 103, the positioning rod 103 can be quickly positioned through the cooperation of the positioning groove 1038 and the positioning block, so as to quickly fix the positioning rod 103. And by providing the positioning groove 1038, even with fewer fixing screws and fixing holes 1037, the fixing of the fixing seat can still be well completed, thereby saving the time for fixing the positioning rod 103.

[0118] In the above-mentioned foot fixing device 100, the positioning rod 103 and the buckle cap 101 are both made of polypropylene (PP) material, the shock pad 102 is made of rubber material, and the positioning rod 103, the shock pad 102 and the buckle cap 101 are respectively integrally formed structures.

[0119] As mentioned above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
