Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, specifically to an anti-icing device for the chassis of an energy-saving building air conditioning unit. Background Technology

[0002] In energy-efficient building water systems, preventing icing on the air conditioning unit chassis is crucial. When the heat pump unit is heating in low-temperature environments, defrosting water from the finned heat exchanger flows into the chassis. If this water is not drained in time, it can easily freeze, affecting the unit's operation. Traditional electric heating defrosting methods are energy-intensive and costly, and may suffer from insufficient power, affecting defrosting efficiency. Furthermore, the harsh installation environment of water-based air conditioning systems places higher demands on chassis anti-icing devices. Therefore, a highly efficient, energy-saving, and reliable chassis anti-icing device is needed to solve these problems.

[0003] Patent CN215260499U discloses an anti-icing mechanism for the chassis of an air conditioner outdoor unit, relating to the field of air conditioners. The outdoor unit includes an evaporator, a compressor, and a condenser, and includes a heating tube assembly. The heating tube assembly includes a copper tube. One end of the copper tube is connected to the evaporator outlet, and the other end is connected to the condenser, used to receive the waste heat emitted by the evaporator. The copper tube is coiled around the lower inner surface of the air conditioner casing to heat the air conditioner casing. This solves the problem that in cold weather, outdoor units of air conditioners are prone to condensation on the condenser, leading to frequent defrosting, and the water after defrosting is easily frozen when flowing through the chassis of the outdoor unit, causing blockage of the drain outlet.

[0004] However, when the above-mentioned device is in use, it is difficult to process the water vapor that evaporates during the heating process of the air conditioner outdoor unit base. This can easily cause the water vapor to condense into water droplets again, which can then freeze in the chassis area, affecting the anti-icing effect of the device. Therefore, an energy-saving building air conditioner main unit chassis anti-icing device is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an anti-icing device for the chassis of an energy-saving building air conditioning unit, addressing the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an anti-icing device for the chassis of an energy-saving building air conditioner, comprising a support frame, a plate mounted on the support frame, an air conditioner body mounted on the plate, a reciprocating screw installed inside the plate, a T-plate movably connected to the circumferential surface of the reciprocating screw, a sliding frame fixedly connected to the inner wall of the plate, a fixed frame fixedly connected to the top of the T-plate, a rotating column rotatably connected to the inner wall of the fixed frame, a heating plate fixedly connected to the circumferential surface of the rotating column, a fixed frame fixedly connected to the top of the fixed frame, a hinged slot plate rotatably connected to the circumferential surface of the fixed frame via a torsion spring, a condenser plate fixedly connected to the inner wall of the air conditioner body, a discharge box fixedly connected to the bottom of the condenser plate, a diagonal rod fixedly connected to the inner wall of the discharge box, a connecting sleeve fixedly connected to the inner wall of the plate, a drain pipe fixedly connected to the bottom of the connecting sleeve, a motor located on the left side of the plate, a temperature sensor located on the inner wall of the plate, and a feature on the inner wall of the plate for preventing internal icing of the plate. The icing drainage mechanism includes a protective mechanism on the inner wall of the plate to prevent pipe icing. A T-plate is slidably connected to the inner wall of the plate. A reciprocating screw is fixedly connected to the output end of a motor. A rotating column contacts a sliding frame. A hinged slot plate contacts a condensing plate and is used to clean and collect water adsorbed and condensed on the surface of the condensing plate. A diagonal rod is located on the movement trajectory of the hinged slot plate. A connecting sleeve communicates with the plate and the drain pipe. This design improves the uniformity of heat coverage by the heating plate, eliminates localized low-temperature dead zones, enhances heat transfer efficiency, accelerates de-icing and preheating speeds, and ensures that water collected inside the air conditioner's plate does not freeze when used in low-temperature weather. It also increases the water drainage speed, extends the air conditioner's lifespan, reduces water vapor condensation at the source, lowers the risk of icing inside the plate, and prevents water vapor from re-contacting the cold surface of the reciprocating screw in low-temperature environments, which would easily condense and freeze again. By improving the anti-icing effect of this device, its anti-icing performance is enhanced.

[0007] Preferably, the drainage mechanism includes a sponge column, a limiting column, a second reciprocating screw, a roller, a preheating column, and a pressure block. The sponge column is fixedly connected to the inner wall of the T-plate, the limiting column is fixedly connected to the inner wall of the T-plate, the second reciprocating screw is rotatably connected to the inner wall of the T-plate, the roller is fixedly connected to the circumferential surface of the second reciprocating screw, the preheating column is fixedly connected to the inner wall of the sponge column, and the pressure block is movably connected to the circumferential surface of the second reciprocating screw. The drainage mechanism also includes an elastic telescopic rod, a fixed plate, a guide ramp, a stop rod, and a dredging column. The elastic telescopic rod is fixedly connected to the inner wall of the disc, the fixed plate is fixedly connected to the telescopic end of the elastic telescopic rod, the guide ramp is fixedly connected to the top of the fixed plate, the stop rod is fixedly connected to the left side of the fixed frame, and the dredging column is fixedly connected to the circumferential surface of the fixed plate. The pressure block is slidably connected to the circumferential surface of the limiting post. The pressure block contacts the sponge column and is used to squeeze the water absorbed by the sponge column. The preheating column contacts the pressure block and is used to prevent the sponge column from freezing. The guide plate is located on the movement trajectory of the push rod and the push rod is used to push the guide plate downward. The roller contacts the disc, so that the pressure block can squeeze out the water absorbed by the sponge column. The water absorbed by the sponge column can be discharged through the pipe in a timely manner, which can effectively prevent the disc from freezing, avoid water accumulation in the disc, improve the drainage efficiency of the device, reduce the probability of freezing inside the disc, and prevent the water inside the disc from not being discharged in time due to freezing inside the connecting sleeve, thus increasing the probability of freezing inside the disc. This can improve the use effect of the device and enhance the anti-icing effect.

[0008] Preferably, the protective mechanism includes a downward column, a base frame, a rotating plate, a lifting plate, and a protective plate. The downward column is fixedly connected to the inner wall of the fixed plate, the base frame is fixedly connected to the bottom of the disc, the rotating plate is rotatably connected to the circumferential surface of the base frame, the lifting plate is fixedly connected to the inner wall of the rotating plate, and the protective plate is fixedly connected to the inner wall of the lifting plate. The protective mechanism also includes a filter plate and a scraper. The filter plate is fixedly connected to the circumferential surface of the fixed plate, and the scraper is fixedly connected to the bottom of the filter plate. The downward column contacts the disc and the rotating plate, and the downward column is used to push the rotating plate to rotate. The filter plate contacts the connecting sleeve, and the scraper contacts the connecting sleeve, and the scraper is used to scrape off the particles remaining on the inner wall of the connecting sleeve. This can accelerate the discharge of water from the drain pipe, prevent blockage inside the drain pipe, ensure that condensate can be discharged smoothly from the reciprocating screw, reduce the possibility of water accumulation and freezing, improve the service life of the device, and enhance the performance of the device.

[0009] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This energy-saving building air conditioning unit chassis anti-icing device, through the coordinated movement of the support frame, panel, air conditioning unit body, reciprocating screw 1, T-plate, slide rail frame, fixed frame, rotating column, heating plate, fixed frame, hinged groove plate, condenser plate, discharge box, diagonal rod, connecting sleeve, and drain pipe, enables the heating plate to improve the uniformity of heat coverage, eliminate local low-temperature dead zones, enhance heat transfer efficiency, accelerate de-icing and preheating speed, ensure that the water collected inside the air conditioning panel will not freeze when the air conditioner is used in low-temperature weather, improve the water discharge speed, extend the service life of the air conditioner, reduce water vapor condensation at the source, reduce the risk of ice formation inside the panel, and prevent water vapor from re-contacting the cold surface of the reciprocating screw 1 in low-temperature environments, which would easily condense and freeze again. By improving the anti-icing effect of this device, the anti-icing performance of the device can be enhanced.

[0010] 2.

Detailed Implementation

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Please see Figures 1-8 One embodiment of the present invention is: an anti-icing device for the chassis of an energy-saving building air conditioner unit, comprising a support frame 1, a plate 2 mounted on the support frame 1, an air conditioner unit 3 mounted on the plate 2, a reciprocating screw 4 disposed inside the plate 2, a T-plate 7 movably connected to the circumferential surface of the reciprocating screw 4, a sliding groove frame 8 fixedly connected to the inner wall of the plate 2, a fixing frame 9 fixedly connected to the top of the T-plate 7, a rotating column 10 rotatably connected to the inner wall of the fixing frame 9, and a heating plate 1 fixedly connected to the circumferential surface of the rotating column 10. 1. A fixed frame 12 is fixedly connected to the top of the fixed frame 9. A hinge slot plate 13 is rotatably connected to the circumferential surface of the fixed frame 12 via a torsion spring. A condenser plate 14 is fixedly connected to the inner wall of the air conditioner body 3. A discharge box 15 is fixedly connected to the bottom of the condenser plate 14. A diagonal rod 16 is fixedly connected to the inner wall of the discharge box 15. A connecting sleeve 17 is fixedly connected to the inner wall of the plate body 2. A drain pipe 18 is fixedly connected to the bottom of the connecting sleeve 17. A motor is provided on the left side of the plate body 2. A temperature sensor is provided on the inner wall of the plate body 2. When the device is used in areas with low temperatures, the motor will start, and the motor's output will drive the reciprocating screw 4 to rotate. The rotation of the reciprocating screw 4 will drive the T-plate 7 to rotate, but the T-plate 7 slides on the inner wall of the disc 2. The disc 2 causes the T-plate 7 to move laterally back and forth only through the reciprocating groove on the surface of the reciprocating screw 4 during the rotation of the reciprocating screw 4. The movement of the T-plate 7 will drive the fixed frame 9 to move synchronously, which in turn will drive the rotating column 10 to move, which in turn will drive the heating plate 11 to move synchronously. When started, the heating plate 11 can generate heat. At the same time, as the rotating column 10 moves, it will come into contact with the sliding frame 8 and generate friction during the movement. The rotating column 10 will rotate during the movement, which will drive the heating plate 11 to rotate. At this time, the heating plate 11 can improve the uniformity of heat coverage, eliminate local low temperature dead zones, enhance heat transfer efficiency, accelerate the melting and preheating speed, ensure that the water collected inside the air conditioner coil 2 will not freeze when the air conditioner is used in low temperature weather, improve the water drainage speed, and improve the service life of the air conditioner. The inner wall of the disc 2 is provided with a drainage mechanism 5 to prevent ice from forming inside the disc 2, and a protective mechanism 6 to prevent ice from forming in the pipes. The T-plate 7 is slidably connected to the inner wall of the disc 2. The reciprocating screw 4 is fixedly connected to the output end of the motor. The rotating column 10 is in contact with the slide frame 8. The hinged slot plate 13 is in contact with the condensing plate 14, and the hinged slot plate 13 is used to clean and collect the water adsorbed and condensed on the surface of the condensing plate 14. The inclined rod 16 is located on the movement trajectory of the hinged slot plate 13. The connecting sleeve 17 is connected to the disc 2 and the drain pipe 18. When the device is used for a long time, the heating plate 11 will indirectly generate a small amount of water vapor during continuous heating. This water vapor will rise and be absorbed by the condenser plate 14, remaining on its surface. During the movement of the fixing frame 9, the fixing frame 9 will simultaneously move the fixing frame 12. The movement of the fixing frame 12 will move the hinged groove plate 13. During this movement, the hinged groove plate 13 can scrape off the water droplets condensed on the surface of the condenser plate 14. The water droplets will then enter the hinged groove plate 13 through its inclined surface. Inside the groove of the body, after the hinged groove plate 13 moves a certain distance, the hinged groove plate 13 will contact the inclined rod 16. During the movement of the hinged groove plate 13, the inclined rod 16 will push the hinged groove plate 13 to rotate through the reaction force. The rotation of the hinged groove plate 13 will cause the water in its own groove to flow into the interior of the discharge box 15, which can reduce water vapor condensation from the source, reduce the risk of ice formation inside the disc 2, and prevent water vapor from contacting the cold surface of the reciprocating screw 4 again in a low temperature environment, which would easily condense into water and freeze again. By improving the anti-icing effect of the device, the anti-icing performance of the device can be strengthened. Overall working principle: The heating plate 11 can improve the uniformity of heat coverage, eliminate local low temperature dead zones, enhance heat transfer efficiency, accelerate the melting and preheating speed, ensure that the water collected inside the air conditioning coil 2 will not freeze when the air conditioner is used in low temperature weather, improve the water discharge speed, and improve the service life of the air conditioner. The rotation of the hinged slot plate 13 will cause the water in its slot to flow into the discharge box 15, which can reduce water vapor condensation from the source, reduce the risk of freezing inside the coil 2, and prevent water vapor from re-contacting the cold surface of the reciprocating screw 4 in a low temperature environment, which would easily condense into water and freeze again. By improving the anti-icing effect of the device, the anti-icing performance of the device can be enhanced.

[0016] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the drainage mechanism 5 includes a sponge column 501, a limiting column 502, a reciprocating screw 503, a roller 504, a preheating column 505, and a pressure block 506. The sponge column 501 is fixedly connected to the inner wall of the T plate 7, the limiting column 502 is fixedly connected to the inner wall of the T plate 7, the reciprocating screw 503 is rotatably connected to the inner wall of the T plate 7, the roller 504 is fixedly connected to the circumferential surface of the reciprocating screw 503, the preheating column 505 is fixedly connected to the inner wall of the sponge column 501, and the pressure block 506 is movably connected to the circumferential surface of the reciprocating screw 503. When the device is started, the movement of T-plate 7 will cause the sponge column 501 to move synchronously. Simultaneously, the movement of T-plate 7 will cause the reciprocating screw 503 to move, which in turn will cause the roller 504 to move. The roller 504 will generate friction due to contact with the disc 2, causing it to rotate during movement. This rotation of the roller 504 will then cause the reciprocating screw 503 to rotate, which in turn will cause the pressure block 506 to rotate. However, the pressure block 506 is limited by the limiting post 502. The limiting post 502 will prevent the pressure block 506 from moving beyond the surface of the reciprocating screw 503 during its rotation. The reciprocating groove on the surface moves laterally back and forth. The reciprocating movement of the pressure block 506 can stop squeezing the sponge column 501. At this time, the sponge column 501 can extend. During the movement, the sponge column 501 will absorb the water inside the disc 2. Similarly, when the sponge column 501 moves back and forth, the sponge column 501 will gradually approach the connecting sleeve 17. At this time, the pressure block 506 will reapply the squeezing force to the sponge column 501. The pressure block 506 can squeeze out the water absorbed in the sponge column 501. The water absorbed by the sponge column 501 can be discharged through the pipe in time, which can effectively prevent the disc 2 from freezing, avoid water accumulation in the disc 2, improve the drainage efficiency of the device, and reduce the probability of freezing inside the disc 2. The drainage mechanism 5 also includes an elastic telescopic rod 507, a fixing plate 508, a guide ramp 509, a stop rod 510, and a dredging column 511. The elastic telescopic rod 507 is fixedly connected to the inner wall of the disc body 2. The fixing plate 508 is fixedly connected to the telescopic end of the elastic telescopic rod 507. The guide ramp 509 is fixedly connected to the top of the fixing plate 508. The stop rod 510 is fixedly connected to the left side of the fixing frame 9. The dredging column 511 is fixedly connected to the circular end of the fixing plate 508. On the circumferential surface, the pressure block 506 is slidably connected to the circumferential surface of the limiting post 502. The pressure block 506 is in contact with the sponge post 501 and is used to squeeze the water absorbed by the sponge post 501. The preheating post 505 is in contact with the pressure block 506 and is used to prevent the sponge post 501 from freezing. The guide plate 509 is located on the movement trajectory of the push rod 510 and the push rod 510 is used to push the guide plate 509 to move downward. The roller 504 is in contact with the disc 2. When the device is started, the fixed frame 9 moves synchronously with the push rod 510. After moving a certain distance, the push rod 510 contacts the guide ramp 509. The push rod 510 continues to move and is pressed and pushed by the ramp of the guide ramp 509. The guide ramp 509 moves downward and moves, which in turn moves the fixed plate 508. The fixed plate 508 moves, which in turn moves the unblocking column 511. During the movement of the unblocking column 511, the unblocking column 511 can unblock the connecting sleeve 17, preventing the water inside the plate 2 from not being able to drain in time due to ice formation inside the connecting sleeve 17, thus increasing the probability of ice formation inside the plate 2. This improves the effectiveness of the device and enhances the anti-icing effect. The protective mechanism 6 includes a downward column 601, a base frame 602, a rotating plate 603, a lifting plate 604, and a protective plate 605. The downward column 601 is fixedly connected to the inner wall of the fixed plate 508, the base frame 602 is fixedly connected to the bottom of the disc body 2, the rotating plate 603 is rotatably connected to the circumferential surface of the base frame 602, the lifting plate 604 is fixedly connected to the inner wall of the rotating plate 603, and the protective plate 605 is fixedly connected to the inner wall of the lifting plate 604. When the device is started, as the fixed plate 508 moves downward, the movement of the fixed plate 508 will drive the downward column 601 to move. The downward column 601 will push the rotating plate 603 to rotate during the movement. The rotation of the rotating plate 603 will drive the lifting plate 604 to rotate at an angle. The rotation of the lifting plate 604 will drive the protective plate 605 to rotate. During the rotation of the lifting plate 604, the lifting plate 604 will come into contact with the drain pipe 18. At this time, the lifting plate 604 can move the drain pipe 18, causing the drain pipe 18 to vibrate and continue to adjust its angle. This can speed up the discharge of water inside the drain pipe 18, prevent blockage inside the drain pipe 18, ensure that condensate can be discharged smoothly from the reciprocating screw 4, and reduce the possibility of water accumulation and freezing. The protective mechanism 6 also includes a filter plate 606 and a scraper 607. The filter plate 606 is fixedly connected to the circumferential surface of the fixed plate 508, and the scraper 607 is fixedly connected to the bottom of the filter plate 606. The downward column 601 contacts the disc 2 and the rotating plate 603. The downward column 601 is used to push the rotating plate 603 to rotate. The filter plate 606 contacts the connecting sleeve 17, and the scraper 607 contacts the connecting sleeve 17. The scraper 607 is used to scrape off the particles remaining on the inner wall of the connecting sleeve 17. When the device is started, the downward movement of the fixed plate 508 will simultaneously drive the filter plate 606 to move downward. The movement of the filter plate 606 will drive the scraper 607 to move. During the movement, the scraper 607 can scrape off the particulate dust attached to the inner wall of the connecting sleeve 17. At the same time, the movement of the filter plate 606 can improve its filtration effect, extend the service life of the device, and improve the performance of the device.

[0017] Overall working principle: The sponge column 501 gradually approaches the connecting sleeve 17. At this time, the pressure block 506 applies pressure to the sponge column 501 again, which can squeeze out the water absorbed by the sponge column 501. This allows the water absorbed by the sponge column 501 to be discharged through the pipe in a timely manner, effectively preventing the disc 2 from freezing and avoiding water accumulation inside the disc 2. This improves the drainage efficiency of the device, reduces the probability of freezing inside the disc 2, and prevents the water inside the disc 2 from being unable to drain in time due to freezing inside the connecting sleeve 17, thus increasing the efficiency of the disc. The probability of internal icing is reduced, which improves the effectiveness of the device and enhances the anti-icing effect. The relative shaking of the drain pipe 18 and the continuous angle adjustment can accelerate the discharge of water inside the drain pipe 18, prevent blockage inside the drain pipe 18, and ensure that condensate can be discharged smoothly. The reciprocating screw 4 reduces the possibility of water accumulation and icing, scrapes off particulate dust attached to the inner wall of the connecting sleeve 17, and at the same time, the movement of the filter plate 606 can improve its filtration effect, thus increasing the service life of the device and improving its effectiveness.
