Description

Technical Field

[0001] The invention relates to the technical field of central air conditioning, in particular to a full-operating-mode central air conditioning system. Background Art

[0002] Central air conditioning is a device that controls different rooms to achieve indoor air conditioning by connecting multiple terminal devices through air ducts or refrigerant pipes. Central air conditioning usually consists of air handling equipment (such as combined air conditioning units, fan coils), heat and humidity treatment equipment (i.e., cold and heat sources or air conditioning hosts), air supply and return air ducts, and various terminal air outlet units (i.e., fan coils or indoor units, etc.).

[0003] Some existing central air conditioners use fan coil units as terminal equipment. The heat medium such as water generated by the central air conditioner host is transported to the fan coil unit at the end, and the air is heated or cooled through the fan coil unit. However, the existing fan coil units are usually compact in structure, which makes it inconvenient to disassemble, and thus makes it inconvenient to clean the internal heat exchange tubes and fins. A large amount of dust accumulation on the heat exchange tubes and fins will cause a decrease in the heat exchange effect, thereby affecting the air conditioning performance.

[0044] The main part of the fan coil unit is arranged inside the installation box 1. When installing the fan coil unit, it is necessary to first fix the installation box 1. The interior of the installation box 1 is divided by a partition 206. After the motor 205 on one side of the partition 206 is connected to an external power supply, it can drive the wind wheel 204 to suck air into the interior. The air flows through the heat pipe 207 and the fin 201 on the other side of the partition 206, thereby achieving the effect of heat exchange, heating or cooling the air and then discharging it. In order to facilitate the user to subsequently install the heat pipe 207 and the fin 201, 01, the first side block 202 and the second side block 203 are connected to both sides of the heat pipe 207, and a support frame 208 is slidably arranged on the outside of the first side block 202 and the second side block 203, and the support frame 208 can slide a certain distance with the installation box 1, so that part of the heat pipe 207 can slide out of the installation box 1, thereby facilitating the cleaning work of the operator, wherein the setting of the support frame 208 enables the heat pipe 207 and the first side block 202 and the side block on both sides to obtain a more stable support effect, thereby ensuring the stability of the cleaning process.

When installing the fan coil unit, it is necessary to first fix the installation box 1. The interior of the installation box 1 is divided by a partition 206. After the motor 205 on one side of the partition 206 is connected to an external power supply, it can drive the wind wheel 204 to suck air into the interior. The air flows through the heat pipe 207 and the fin 201 on the other side of the partition 206, thereby achieving the effect of heat exchange, heating or cooling the air and then discharging it. Among them, in order to facilitate the user to clean the heat pipe 207 and the fin 201 later, the two sides of the heat pipe 207 are connected to the first side block 202 and the second side block 203, and the first side block 202 and the second side block 203 are slidably provided with a support frame on the outside. 208, and the support frame 208 can slide a certain distance with the installation box 1, so that the heat pipe 207 part can slide out of the installation box 1, thereby facilitating the cleaning work of the operator, wherein the setting of the support frame 208 enables the heat pipe 207 and the first side blocks 202 and the side blocks on both sides to obtain a more stable support effect, ensuring the stability of the cleaning process. When the heat pipe 207 is slid out through the first side block 202 and the second side block 203, an inclined clamping block 603 is provided on the inner side of the second side block 203. When the heat pipe 207 part completely slides out of the installation box 1, the inclined clamping block 603 will be engaged with the first clamping groove 605 on the side of the installation box 1 under the push of the sixth spring 604, thereby preventing the current sliding of the second side block 203. After the cleaning work is completed, the user can press the release rod 601 on the second side block 203, so that the end of the release rod 601 pushes the inclined surface block 603 through the inclined surface action, thereby releasing the engagement state between the inclined surface block 603 and the first card slot 605 on the installation box 1, which is convenient for operation. The ends of the two installation pipes 505 for inputting and outputting the heat exchange medium are located on the side of the installation box 1. In order to clean the heat pipe 207, the heat pipe 207 will be disconnected from the installation pipe 505. For the convenience of control, a connecting block 502 is provided on the inner side of the first side block 202. The two connecting blocks 502 respectively connect the head and tail ends of the multiple heat pipes 207, and a connecting pipe 505 is provided between the connecting block 502 and the installation pipe 505. 01, the connecting pipe 501 is arranged on the inner side of the mounting block 210. When the end of the connecting pipe 501 slides away from the connecting block 502, the first sealing block 503 on the inner side of the connecting block 502 will seal the opening on the side of the connecting block 502 under the action of the third spring 504. At this time, the first side block 202 can be slid out of the mounting box 1 to clean the heat pipe 207. At the same time, as the connecting pipe 501 slides to the side of the mounting pipe 505, the blocking block 508 arranged on the inner side of the connecting pipe 501 will push the second sealing block 506 to contact and seal with the end of the connecting pipe 501. At this time, the continuous leakage of the heat exchange medium can be avoided and the blocking effect can be exerted. After the cleaning is completed, the connecting pipe 501 is slid back to the direction of the first side block 202 in response to the reset of the first side block 202.The ends of the connecting pipe 501 are provided with holes on both sides. The ends of the connecting pipe 501 will push the first sealing block 503, and at the same time, the sealing state is released, so that the installation pipe 505 is reconnected with the connecting block 502, so as to ensure the re-flow of the heat exchange medium and improve the convenience of cleaning work. In order to facilitate the control of the movement of the connecting pipe 501 and thus the flow state of the heat exchange medium inside the device, a traction groove block 403 is provided at the ends of the two connecting pipes 501. The user can rotate the rocker 401 located on the side of the mounting block 210 so that the sliding column 404 at the end of the rocker 401 slides in the groove on the side of the traction groove block 403, and then the connecting pipe 501 is pulled to slide by the sliding of the traction groove block 403, and at the same time, the traction groove block 403 is pulled to slide. When the connecting tube 501 is pushed to slide toward the connecting block 502, the connecting tube 501 and the heat pipe 207 are in a connected state. At the same time, the end of the rocker 401 will conflict with the first side block 202, thereby preventing the first side block 202 from sliding, thereby ensuring the stable operation of the device. At the same time, in order to ensure that the rotation angle of the rocker 401 can accurately control the sliding distance of the traction slot block 403, an arc-shaped limiting groove 402 is provided on the side of the mounting block 210. When the end of the engaging rod 405 on the inner side of the rocker 401 slides to the end of the limiting groove 402, if the engaging rod 405 is released, the end of the engaging rod 405 will engage with the limiting groove 402, thereby fixing the current position of the connecting tube 501 and maintaining the connected or disconnected state. The end of the air outlet plate 301 is provided with an air outlet plate 301, and the air outlet plate 301 can be opened and closed by sliding longitudinally. At the same time, a plurality of groups of blades 302 are provided in the middle of the air outlet plate 301, and gears 305 are provided at the ends of the blades 302. The gears 305 are meshed with the threaded tooth blocks 304 provided in the middle. The user can rotate the adjusting screw 303 located on the bottom side to drive the threaded tooth blocks 304 to slide, thereby driving the blades 302 to rotate to adjust the wind direction. On the other hand, in order to facilitate the fixation between the air outlet plate 301 and the installation box 1, a locking block 306 is provided on the inner side of the air outlet plate 301. When the side of the installation box 1 needs to be closed by the air outlet plate 301, the user can press the adjusting screw 303 so that the adjusting screw 303 is locked. The square part slides into the square groove part on the inner side of the locking block 306. At this time, rotating the adjusting screw 303 can rotate the pushing part on the side of the locking block 306 to one side. At this time, the air outlet plate 301 is lifted to the side of the installation box 1, and the adjusting screw 303 is released. Under the action of the torsion spring 307, the protruding part on the side of the locking block 306 is screwed into the locking groove 313 on the side of the installation box 1 to fix the air outlet plate 301. A contact plate 311 is provided on the top side of the adjusting screw 303 to facilitate the reset of the adjusting screw 303. At the same time, a first positioning groove 308 is opened on the side of the adjusting screw 303. The positioning effect of the positioning plates 309 on both sides can facilitate the square part of the adjusting screw 303 to slide correctly into the square groove on the inner side of the locking block 306.The locking state of the air outlet plate 301 is then controlled for easy operation. In order to reduce the dust in the air sucked by the wind wheel 204, an air filter plate 701 is provided in the opening on the bottom side of the installation box 1. The air filter plate 701 has a reduced filtering capacity after long-term use. At this time, the user can rotate the air filter plate 701. A semicircular protrusion is provided at the end of the connecting frame 702. As the connecting frame 702 rotates, the semicircular protrusion at the end thereof rotates to align with the spherical groove 707 at the end of the engaging column 704. At this time, the seventh spring 706 Under the push of , the engaging column 704 slides and releases the engaging state with the second engaging slot 705. The user can slide down the lifting frame 703 to clean the air filter plate 701. After cleaning, the lifting frame 703 is lifted up again, and then the air filter plate 701 is rotated to a horizontal state. At this time, the positioning effect of the positioning block 708 on the connecting frame 702 can keep the air filter plate 701 in a horizontal state, and at the same time, the engaging column 704 is reengaged with the second engaging slot 705, thereby completing the cleaning of both sides of the air filter plate 701.
