[0023] See also Figure 1-Figure 2 The present invention provides an embodiment: an energy-saving ventilation heat recovery central air-conditioning integrated machine, comprising a box body 100, and a fresh air mechanism 200 and an exhaust mechanism 300 respectively installed on both sides of the box body 100, the fresh air mechanism 200 is used to transport fresh air from the outside to the room, the fresh air mechanism 200 is provided with a left air inlet chamber and a right air inlet chamber, a driving motor and a fan are installed inside the left air inlet chamber, the exhaust mechanism 300 is used to discharge the dirty air in the room to the outside, the exhaust mechanism 300 is provided with a left air outlet chamber and a right air outlet chamber, a driving motor and a fan are installed inside the right air outlet chamber, a heat exchange mechanism 400 is installed in the middle of the inner side of the box body 100, the heat exchange component 410 is located in the middle position of the fresh air mechanism 200 and the exhaust mechanism 300, and a filter 500 is installed in the right chamber of the fresh air mechanism 200.

[0024] It should be noted that the driving motor and fan of the fresh air mechanism 200 can draw outdoor fresh air into the right air inlet chamber. The fresh air entering the right air inlet chamber can filter impurities in the air through the filter 500. After filtering, the fresh air enters the left air inlet chamber through the heat exchange component 410. After entering the left air inlet chamber, the fresh air will be discharged into the room. At the same time, the driving motor and fan of the exhaust mechanism 300 can draw indoor turbid air into the left air outlet chamber. After entering the left air outlet chamber, the turbid air can enter the right air outlet chamber through the heat exchange component 410. The right air outlet chamber can discharge the turbid air to the outside. The turbid air and the fresh air will perform heat exchange when passing through the heat exchange component 410.

[0025] like Figure 1-Figure 4 As shown, the heat exchange mechanism 400 includes a heat exchange component 410 fixedly installed at the middle position of the inner side of the box body 100, and the heat exchange component 410 includes a heat exchange cover 411 fixedly installed at the middle position of the inner side of the box body 100, and an exhaust chamber 412 opened inside the heat exchange cover 411, the exhaust chamber 412 is used to transport the dirty air from the inside of the exhaust mechanism 300 on the left to the inside of the exhaust mechanism 300 on the right, and a spiral conveying pipe 413 is installed inside the exhaust chamber 412, and the spiral conveying pipe 413 is used to transport fresh air from the inside of the fresh air mechanism 200 on the right to the inside of the fresh air mechanism 200 on the left. When the fresh air enters the exhaust chamber 412 and the spiral conveying pipe 413, heat exchange will occur. Both ends of the spiral conveying pipe 413 are fixedly connected with the air inlet pipe 414. The sides of the air inlet pipe 414 are respectively connected to the left air inlet chamber and the right air inlet chamber of the fresh air mechanism 200 through the air inlet port 415. Both sides of the heat exchange cover 411 are penetrated by connecting pipes 418. One end of the connecting pipe 418 passes through the heat exchange cover 411 and is connected to the inside of the exhaust chamber 412. The other ends of the two groups of connecting pipes 418 are connected to the air outlet pipe 417. The sides of the air outlet pipe 417 are respectively connected to the left air outlet chamber and the right air outlet chamber of the exhaust mechanism 300 through the air outlet port 416.

[0026] It should be understood that air can enter the interior of the air inlet 415 through the right side fresh air intake chamber of the fresh air mechanism 200, and the fresh air inside the air inlet 415 can enter the interior of several groups of spiral conveying pipes 413 respectively through the air inlet pipes 414, and the fresh air can exchange heat with the turbid air when entering the spiral conveying pipes 413. After the heat exchange of the fresh air, the fresh air can enter the interior of the left side air inlet pipe 414 through the other end of the spiral conveying pipe 413, and the left side air inlet pipe 414 can be transported to the left side fresh air intake chamber through the air inlet 415, and the left side fresh air intake chamber can transport the fresh air into the room. At the same time, the turbid air in the room can be transported to the left side air outlet 416 through the left side air outlet chamber of the exhaust mechanism 300, and the left side outlet The air outlet 416 can transport the foul air to the interior of several groups of exhaust chambers 412 through the air outlet pipe 417 and the connecting pipe 418. When the foul air enters the exhaust chamber 412, it will exchange heat with the fresh air in the spiral conveying pipe 413. After the heat exchange, the foul air can enter the air outlet pipe 417 through the connecting pipe 418 on the right side of the exhaust chamber 412. The foul air in the air outlet pipe 417 then enters the right air outlet chamber of the exhaust mechanism 300 through the air outlet 416. The right air outlet chamber of the exhaust mechanism 300 can discharge the foul air after heat exchange into the room. When the fresh air and the foul air are exchanging heat, the spiral conveying pipe 413 will be completely wrapped in the foul air, thereby maximizing the efficiency of heat exchange and reducing the energy consumption of the air conditioner.

[0027] like Figure 2-Figure 5 As shown, a collecting assembly 420 for collecting condensate is installed on the heat exchange assembly 410. The collecting assembly 420 includes an L-shaped drain pipe 421 fixedly installed on the surface of the spiral conveying pipe 413, and a collecting port 425 fixedly connected to the outer surface of the L-shaped drain pipe 421. The L-shaped drain pipe 421 is used to collect condensate inside the spiral conveying pipe 413, and the collecting port 425 is used to collect condensate on the outer surface of the spiral conveying pipe 413. One end of the L-shaped drain pipe 421 passes through the heat exchange cover 411 and is connected to a recovery pipe 427. A baffle plate 422 is rotatably connected to the inner side of the liquid pipe 421, a blocking block 423 is fixedly connected to the inner wall of the L-shaped drainage pipe 421 near the upper edge of the baffle plate 422, a counterweight block 424 is fixedly connected to the lower edge of the baffle plate 422, a liquid inlet hole 426 is provided on the surface of the L-shaped drainage pipe 421 near the inner side of the collecting port 425, a collecting box 428 is fixedly connected to the bottom of the box body 100, the lower end of the recovery pipe 427 passes through the bottom of the box body 100 and is connected to the inside of the collecting box 428, and an overflow port 429 is installed on the side of the collecting box 428.

[0028] It is worth noting that condensed water will appear when the fresh air exchanges heat with the stagnant air. When the fresh air temperature is high and the stagnant air temperature is low, the condensed water will adhere to the inner wall of the spiral conveying pipe 413. On the other hand, when the fresh air temperature is low and the stagnant air temperature is high, the condensed water will adhere to the outer surface of the spiral conveying pipe 413. Whether the condensed water adheres to the inner wall or the outer surface of the spiral conveying pipe 413, it will slide down through the arc shape of its surface. When the condensed water on the inner wall of the spiral conveying pipe 413 slides down, it will flow to the baffle 422 on the inner side of the L-shaped drain pipe 421. When the weight of the condensed water on the baffle 422 exceeds the counterweight 424, the baffle 422 will be moved. When the baffle 422 rotates, the condensed water can be transported to the inside of the recovery pipe 427 through the L-shaped drain pipe 421, and the recovery pipe 427 can transport the condensed liquid to the inside of the collection box 428. When the condensed water on the outer surface of the spiral conveying pipe 413 slides downward, it will drip into the inside of the collection port 425. When the condensed water enters the inside of the collection port 425, it can be transported to the inside of the L-shaped drain pipe 421 through the liquid inlet hole 426. The condensed water inside the L-shaped drain pipe 421 can be transported to the inside of the collection box 428 through the recovery pipe 427. When the condensed water inside the collection box 428 is full, it can be discharged through the overflow port 429.

The water outlet pipe 5115 can spray the condensate collected by the L-shaped drain pipe 421 and the collection port 425 onto the filter screen 500 for cleaning. Two groups of operating grooves 511 are opened on the surface of the filter screen 500. A reciprocating screw rod 512 is rotatably connected to the inside of the operating groove 511. The reciprocating screw rod 512 is rotatably connected to the inside of the operating groove 511. A motor 513 is installed at the bottom end of the screw rod 512, and the motor 513 is installed at the bottom of the box body 100. The surface of the reciprocating screw rod 512 is threadedly connected with an internal thread slider 514, and the internal thread slider 514 is movably connected to the inside of the operating groove 511. A sewage outlet 5123 is installed through the inner side of the fresh air mechanism 200 close to the filter 500. The operating groove 511 is fixedly connected to the inside of the reciprocating screw rod 512 away from the reciprocating screw rod 512. The surface of the limit rod 515 is movably connected with a slider 516, and the side of the slider 516 is movably connected to the inside of the operating groove 511. The surface of the slider 516 and the surface of the internal thread slider 514 are both installed with a bearing seat 517, and the inner side of the bearing seat 517 is rotatably connected with a rotating tube 518 , a plurality of rotating tubes 518 are provided, and adjacent rotating tubes 518 are connected to each other through guide plate 1 519 and guide plate 2 5110, respectively. The inclination angles of guide plate 1 519 and guide plate 2 5110 are opposite to each other. A gear 5112 is fixedly installed on one end of the rotating tube 518, and a tooth groove 5113 matching the gear 5112 is provided on the surface of the filter screen 500 close to the limit rod 515. A bearing 5114 is installed on the inner side of the cavity at the other end of the rotating tube 518, and a water outlet pipe 5115 is rotatably connected to the inner side of the bearing 5114. A nozzle 5116 is installed on the surface of the water outlet pipe 5115 close to the guide plate 1 519 and the guide plate 2 5110, and the water outlet pipe 5115 close to the reciprocating screw rod 5 One end of the filter screen 500 is fixedly connected to a guide block 5117, a guide groove 5118 is provided on the surface of the filter screen 500 near the guide block 5117, and the guide block 5117 is movably connected inside the guide groove 5118. The surface of the water outlet pipe 5115 is connected to one end of a hose 5119, and the other end of the hose 5119 is connected to one end of a water pipe 5120. The side of the water pipe 5120 passes through the bottom of the box body 100, and the bottom end of the water pipe 5120 is connected to the output end of a water pump 5121. The water pump 5121 is installed on the side of the collection box 428, and the input end of the water pump 5121 is connected to the inside of the collection box 428 through a pipeline. A wind speed sensor 5122 is installed on the inner wall of the air inlet 415 near the filter screen 500.

[0030] It can be understood that the fresh air enters the interior of the air inlet 415 through the right air inlet chamber of the fresh air mechanism 200. When the fresh air enters the interior of the air inlet 415, the filter 500 will filter the dust and impurities inside the fresh air. The long-term use of the filter 500 will gradually accumulate dust and impurities on the surface, which will cause the air intake speed of the fresh air mechanism 200 to gradually decrease. The wind speed sensor 5122 on the inside of the air inlet 415 will monitor the air intake speed in real time. When the wind speed detected by the wind speed sensor 5122 is lower than the specified value, it will send instructions to the motor 513 and the water pump 5121 to work respectively. When the motor 513 works, it drives the reciprocating screw 512 to rotate. When the reciprocating screw 512 rotates, it can drive the internal thread slider 514 The internal thread slider 514 slides up and down inside the operating groove 511 when the internal thread slider 514 slides up and down when sliding. When the internal thread slider 514 slides up and down, it drives the bearing seat 517 to move. When the bearing seat 517 moves, it drives the rotating tube 518, the roller brush 5111 and the water outlet pipe 5115 to move. When the water outlet pipe 5115 moves, it can drive the guide block 5117 at the end to slide inside the guide groove 5118. When the rotating tube 518 moves, it can drive the guide plate 1 519 and the guide plate 2 5110 to move. When the guide plate 1 519 and the guide plate 2 5110 move, they can drive the remaining rotating tubes 518 to move. When the rotating tube 518 moves, it drives the gear 5112 at the end to When the rotating tube 518 near the gear 5112 moves, it can drive the slider 516 to slide on the surface of the limit rod 515 through the bearing seat 517. When the gear 5112 moves, it meshes and rotates through the tooth groove 5113. When the rotating tube 518 near the gear 5112 rotates, it can drive the guide plate 1 519 and the guide plate 2 5110 to rotate. When the guide plate 1 519 and the guide plate 2 5110 rotate, they can drive the remaining rotating tubes 518 to rotate. When the rotating tube 518 rotates, it can drive the roller brush 5111 and the water outlet pipe 5115 to rotate. When the roller brush 5111 rotates, it can clean the surface of the filter screen 500. When the rotating tube 518 rotates, it can rotate through the bearing 51 14 rotates with the outlet pipe 5115, and at the same time, the water pump 5121 can pump the condensed water inside the collection box 428 to the inside of the outlet pipe 5115 through the water pipe 5120 and the hose 5119. When the condensed water enters the outlet pipe 5115, it can be sprayed onto the surface of the filter 500 through the nozzle 5116 for cleaning. When the guide plate 1 519 and the guide plate 2 5110 rotate to the condensed water spraying path, the condensed water spraying angle can be changed, thereby increasing the cleaning area of ​​the filter 500 by the condensed water, so that the filter 500 can be cleaned more cleanly. After the filter 500 is cleaned, the sewage can fall to the bottom of the right air inlet chamber of the fresh air mechanism 200 and be discharged to the outside through the sewage outlet 5123.
