Description

Technical Field

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

[0002] As the core energy-consuming equipment in energy-efficient buildings, water-based air conditioning systems are widely used in medium and large-sized energy-efficient buildings due to their advantages of high heat exchange efficiency and low energy consumption in transmission and distribution. However, when operating in low-temperature environments in winter, the problem of ice formation on the chassis of the air conditioning unit has become a key pain point that restricts the stable operation of water-based air conditioning systems and affects energy-saving effects, which has also created an urgent need for dedicated anti-icing devices.

[0003] Patent CN216481564U discloses a water tray assembly for air conditioning equipment that facilitates drainage and impurity removal. The assembly includes an air conditioning unit. Before use, a threaded seat and an auxiliary mounting base are fixed to the bottom of the air conditioning unit via threaded connectors. A scraping device is inserted into a groove on the side wall of the tray. A drive unit and cylinder are fixed to the top of the chassis, and the chassis is fixed to the side of the tray, ensuring that the cylinder, telescopic rod, and scraper are kept on a horizontal line. During use, wastewater inside the air conditioner is first pre-screened through a mesh on the preliminary filtering device to prevent large-scale blockage of the leakage device. After a period of time, dust will accumulate on the surface of the tray. At this time, the cylinder is activated, and the cylinder drives the scraper to move back and forth at the bottom of the tray through the telescopic rod. Under the combined action of water flow, the impurities inside the tray are removed into the anti-clogging device and finally discharged through the hose. Although the device can clean the impurities out through the bottom, prevent equipment blockage and improve drainage efficiency, when the device is used for internal heating and antifreeze, it is easy to cause heated water molecules to remain inside the equipment. It is difficult to treat the water vapor inside after cooling, which further reduces the heat exchange efficiency. Therefore, an energy-saving building water system air conditioning unit chassis anti-icing device is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an anti-icing device for the chassis of an air conditioning unit in an energy-saving building water system, which addresses the shortcomings of the prior art.

[0005] 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 water system air conditioning unit, comprising a casing, a fixed bracket fixedly connected to the top of the casing, an outer shell fixedly connected to the outer surface of the fixed bracket, a PLC heating device installed on the inner wall of the outer shell, an icing probe installed on the top of the outer shell, a power signal line fixedly connected to the inner wall of the outer shell, an anti-clogging mechanism for preventing blockage of the equipment outlet on the inner wall of the outer shell, a positioning mechanism for positioning during installation on the bottom of the casing, and a collection box fixedly connected to the bottom of the outer shell. The inner wall of the collection box is rotatably connected to a reciprocating screw, the circumferential surface of the reciprocating screw is movably connected to a sliding plate, the inner wall of the sliding plate is slidably connected to a sponge plate, the inner wall of the collection box is fixedly connected to a limit rod, and the inner wall of the outer shell is fixedly connected to a condensation plate. In winter, the outer shell is started to work through the power signal line to prevent the chassis structure from deforming or cracking due to the expansion stress of ice, and to prevent ice from blocking the drain hole and aggravating the vicious cycle of water accumulation. This improves the working efficiency of the equipment in winter. Also, ice may jam the fan blades or affect the airflow of the heat exchanger, causing abnormal operation or even damage to the equipment, thus improving the service life of the equipment.

[0006] The top of the outer casing contacts the bottom of the housing, and the top of the icing probe contacts the bottom of the housing. The power signal line away from the outer casing is fixedly connected to the inner wall of the housing. A motor is fixedly connected to the front of the collection box, and the output end of the motor is fixedly connected to the front of the reciprocating screw. A sensor is installed on the inner wall of the outer casing, and the sensor is activated by detecting the temperature of the housing through the icing probe. The sliding plate is slidably connected to the inner wall of the collection box, and the inner wall of the sliding plate contacts the circumferential surface of the limiting rod. The sponge plate contacts the top of the outer casing, and the sponge plate moves on the trajectory of the condenser plate, and the sponge plate contacts the inner wall of the collection box. When the sensor inside the outer casing activates the PLC heating device, the motor drives the reciprocating screw to rotate, and the reciprocating screw drives the sponge plate to wipe the bottom of the condenser plate back and forth, avoiding the decrease in heat exchange efficiency caused by icing, thereby improving the cooling or heating effect of the air conditioner. The sponge has good water absorption and wiping ability, which can reduce heat exchange resistance and improve heat exchange efficiency, thereby improving the cooling or heating effect.

[0007] Preferably, the anti-clogging mechanism includes a fixed rod, a pulley rotatably connected to the inner wall of the fixed rod, a trapezoidal plate fixedly connected to the inner wall of the collection box, and a squeezing plate fixedly connected to the bottom of the outer shell. While cleaning the condensate at the bottom of the condensation plate, the sliding plate drives the squeezing plate to work with the trapezoidal plate to squeeze the sponge plate from top to bottom simultaneously. Squeezing the sponge can more effectively remove the water inside the sponge, avoid water residue, and thus improve cleaning efficiency. By squeezing the sponge, water can be discharged from the sponge, reducing water splashing and improving the user experience.

[0008] The inner wall of the outer casing is slidably connected to a drain plate via a spring. An L-shaped rod is fixedly connected to the bottom of the drain plate, and a pulley is rotatably connected to the inner wall of the L-shaped rod. The bottom of the sponge board is fixedly connected to the top of the fixed rod, and the fixed rod is slidably connected to the inner wall of the sliding plate. The pulley moves along the trajectory of the trapezoidal plate, and the sponge board moves along the trajectory of the extrusion plate. The extrusion plate contacts the bottom of the outer casing, the L-shaped rod contacts the inner wall of the collection box, and the pulley moves along the trajectory of the sliding plate. While pressurizing the condensate, the sliding plate reciprocates, driving the drain plate to reciprocate and clear the drain outlet of the outer casing. Regular clearing prevents poor drainage, thus avoiding blockages. Regular clearing also reduces corrosion and damage, extending the service life of the pipes. It not only effectively prevents and solves drainage problems but also improves equipment efficiency.

[0009] Preferably, the positioning mechanism includes a support rod, which is slidably connected to a moving rod via a spring. A positioning plate is fixedly connected to the side of the moving rod near the fixed bracket. When the outer casing is being repaired, the positioning plate works with the fixed bracket to position the outer casing, preventing equipment offset or instability caused by improper installation. Through the cooperation of the positioning part and the positioning mating part, the chassis and chassis bracket can be pre-positioned, improving the stability and reliability of the installation, and also enhancing the smoothness of equipment operation.

[0010] The inner wall of the unblocking plate is rotatably connected to a rotating rod, and gears are fixedly connected to the front and rear sides of the rotating rod. A rotating shaft is fixedly connected to the circumferential surface of the rotating rod, and a rack is fixedly connected to the top of the outer casing. The bottom of the casing is fixedly connected to the top of the support rod, the positioning plate contacts the top of the fixed bracket, and the circumferential surface of the gear meshes with the top of the rack. While unblocking the internal drain outlet of the outer casing, the reciprocating movement of the unblocking plate will drive the rotating rod to rotate, thereby cleaning the drain outlet. It can break up larger impurities and ice blocks in the drain outlet, effectively agitate the water in the drain outlet, prevent the water from freezing or settling due to stillness, and thus improve drainage efficiency.

[0011] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0012] 1.

Ice may jam the fan blades or affect the airflow of the heat exchanger, leading to abnormal operation or even damage to the equipment, thus extending the service life of the equipment. When the sensor inside the outer shell activates the PLC heating device, the motor drives the reciprocating screw to rotate, and the reciprocating screw drives the sponge plate to wipe the bottom of the condenser plate back and forth, avoiding the decrease in heat exchange efficiency caused by icing, thereby improving the cooling or heating effect of the air conditioner. The sponge has good water absorption and wiping ability, which can reduce heat exchange resistance and improve heat exchange efficiency, thereby enhancing the cooling or heating effect.

[0013] 2. This energy-saving building water system air conditioning unit chassis anti-icing device, through the coordinated operation of a fixed rod, a pulley, a trapezoidal plate, and a squeezing plate, cleans the condensate at the bottom of the condenser plate while the sliding plate drives the squeezing plate to simultaneously squeeze the sponge plate from top to bottom in conjunction with the trapezoidal plate. Squeezing the sponge can more effectively remove the water inside the sponge, avoid water residue, and thus improve cleaning efficiency. By squeezing the sponge, water can be discharged from the sponge, reducing water splashes and improving the user experience.

[0014] 3. This energy-saving building water system air conditioning unit chassis anti-icing device, through the coordinated operation of the unblocking plate, L-shaped rod and pulley, pressurizes the condensate while the sliding plate reciprocates to drive the unblocking plate to reciprocate to unblock the drain outlet of the outer shell. Regular unblocking can prevent poor drainage and thus avoid blockage. Regular unblocking can reduce corrosion and damage, extend the service life of the pipes, effectively prevent and solve drainage problems, and improve equipment working efficiency.

[0015] 4. This energy-saving building water system air conditioning unit chassis anti-icing device, through the cooperation of support rod, moving rod and positioning plate, when the outer shell is being maintained, the positioning plate cooperates with the fixed bracket to position the outer shell, avoiding equipment displacement or instability caused by improper installation. Through the cooperation of the positioning part and the positioning mating part, the chassis and chassis bracket can be pre-positioned, improving the stability and reliability of installation, and at the same time improving the smoothness of equipment operation.

[0016] 5. This energy-saving building water system air conditioning unit chassis anti-icing device, through the coordinated operation of the rotating rod, gear, rack and pinion, clears the internal drain outlet of the outer casing while the reciprocating movement of the clearing plate drives the rotating rod to rotate, thereby cleaning the drain outlet.

[0027] 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.

[0028] Please see Figures 1-9 One embodiment of the present invention is: an anti-icing device for the chassis of an air conditioning unit for an energy-saving building water system, comprising a housing 1, a fixed bracket 3 fixedly connected to the top of the housing 1, an outer shell 2 fixedly connected to the outer surface of the fixed bracket 3, a PLC heating device 4 installed on the inner wall of the outer shell 2, an icing probe 5 installed on the top of the outer shell 2, a power signal line 6 fixedly connected to the inner wall of the outer shell 2, an anti-clogging mechanism 7 for preventing blockage of the equipment outlet on the inner wall of the outer shell 2, a positioning mechanism 8 for positioning during installation on the bottom of the housing 1, a collection box 14 fixedly connected to the bottom of the outer shell 2, a reciprocating screw 9 rotatably connected to the inner wall of the collection box 14, a sliding plate 10 movably connected to the circumferential surface of the reciprocating screw 9, a sponge plate 11 slidably connected to the inner wall of the sliding plate 10, a limit rod 13 fixedly connected to the inner wall of the collection box 14, and a condensation plate 12 fixedly connected to the inner wall of the outer shell 2;

[0029] In winter, when residents use air conditioners, the outdoor unit of the air conditioner, which operates in low-temperature environments, is prone to water accumulation on its chassis due to poor condensate drainage or high ambient humidity. When the unit 1 is working, it will send an electrical signal to the inside of the outer casing 2 through the power signal line 6. When the temperature is below freezing, the water will freeze and gradually accumulate. At this time, the outdoor unit will detect that the ambient temperature is <2℃ and the icing probe 5 is not conducting for a long time. Combined with the compressor's operating status, it is judged that there may be ice on the chassis causing airflow obstruction. At this time, the sensor will automatically reduce the operating power through the control module or start the PLC heating device 4 to heat for 1-2 minutes for a short time, thereby melting the surface ice and restoring normal operation. This prevents the chassis structure from being deformed or cracked due to the expansion stress of the ice, and prevents ice from blocking the drain hole, which will aggravate the vicious cycle of water accumulation. This improves the working efficiency of the equipment in winter. Ice may also block the fan blades or affect the airflow of the heat exchanger, causing abnormal operation or even damage to the equipment, thus improving the service life of the equipment.

[0030] The top of the outer casing 2 contacts the bottom of the casing 1, the top of the icing probe 5 contacts the bottom of the casing 1, and the power signal line 6 is fixedly connected to the inner wall of the casing 1 on the side away from the outer casing 2. A motor is fixedly connected to the front of the collection box 14, and the output end of the motor is fixedly connected to the front of the reciprocating screw 9. A sensor is provided on the inner wall of the outer casing 2, and the sensor is activated by detecting the temperature of the casing 1 through the icing probe 5. The sliding plate 10 is slidably connected to the inner wall of the collection box 14, and the inner wall of the sliding plate 10 contacts the circumferential surface of the limit rod 13. The sponge plate 11 contacts the top of the outer casing 2, and the sponge plate 11 moves on the movement trajectory of the condensation plate 12, and the sponge plate 11 contacts the inner wall of the collection box 14.

[0031] When the sensor inside the outer casing 2 activates the PLC heating device 4, water vapor is generated inside the outer casing 2. This vapor condenses on the bottom of the condenser plate 12. The sensor then sends an electrical signal to start the motor. The motor drives the reciprocating screw 9 to rotate through its output. The reciprocating screw 9 rotates and contacts the inner wall of the sliding plate 10 through the reciprocating groove on the circumferential surface, causing the sliding plate 10 to move back and forth. The sliding plate 10 then moves the sponge plate 11 back and forth, allowing the sponge plate 11 to wipe the bottom of the condenser plate 12. This allows the condenser plate 12 to continue supporting its function and prevents a decrease in heat exchange efficiency due to icing, thereby improving the cooling or heating effect of the air conditioner. The sponge has good water absorption and wiping ability, which can reduce heat exchange resistance and improve heat exchange efficiency, thus enhancing the cooling or heating effect.

[0032] Working principle: In winter, the outer casing 2 is activated via the power signal line 6 to prevent deformation and cracking of the chassis structure due to the expansion stress of ice, which could lead to blockage of the drainage holes and exacerbate the vicious cycle of water accumulation. This improves the equipment's working efficiency and extends its service life in winter. When the PLC heating device 4 is activated by the sensor inside the outer casing 2, the motor drives the reciprocating screw 9 to rotate. The reciprocating screw 9 drives the sponge plate 11 to wipe the bottom of the condenser plate 12, thereby improving the cooling or heating effect of the air conditioner. The sponge has good water absorption and wiping ability, which can reduce heat exchange resistance and improve heat exchange efficiency, thus enhancing the cooling or heating effect.

[0033] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, the anti-blocking mechanism 7 includes a fixing rod 71, a pulley 72 rotatably connected to the inner wall of the fixing rod 71, a trapezoidal plate 73 fixedly connected to the inner wall of the collection box 14, and a squeezing plate 74 fixedly connected to the bottom of the outer shell 2.

[0034] While cleaning the condensate at the bottom of the condensation plate 12, the sponge plate 11 moves back and forth along the movement trajectory of the squeezing plate 74. The sponge plate 11 is squeezed by the squeezing plate 74, thus squeezing out the water inside the sponge plate 11. As the sponge plate 11 moves, it drives the fixing rod 71 to move. The fixing rod 71 drives the pulley 72 to move, so that the circumferential surface of the pulley 72 contacts the inclined surface of the trapezoidal plate 73, thus driving the pulley 72 to move. The pulley 72 drives the fixing rod 71 to move, and the pulley 72 drives the sponge plate 11 to move upward. Thus, the squeezing plate 74, together with the trapezoidal plate 73, squeezes the sponge plate 11 from both above and below. Squeezing the sponge can more effectively remove the water inside the sponge, avoid water residue, and improve cleaning efficiency. By squeezing the sponge, water can be discharged from the sponge, reducing water splashes and improving the user experience.

[0035] The inner wall of the outer shell 2 is slidably connected to a drain plate 75 via a spring. An L-shaped rod 76 is fixedly connected to the bottom of the drain plate 75. A pulley 77 is rotatably connected to the inner wall of the L-shaped rod 76. The bottom of the sponge plate 11 is fixedly connected to the top of the fixed rod 71. The fixed rod 71 is slidably connected to the inner wall of the sliding plate 10. The pulley 72 moves on the movement trajectory of the trapezoidal plate 73, and the sponge plate 11 moves on the movement trajectory of the squeezing plate 74. The squeezing plate 74 contacts the bottom of the outer shell 2. The L-shaped rod 76 contacts the inner wall of the collection box 14, and the pulley 77 moves on the movement trajectory of the sliding plate 10.

[0036] While pressurizing the condensate, the sliding plate 10 reciprocates and contacts the rotating circumferential surface of the second pulley 77 through the inclined surface, thereby driving the second pulley 77 to move. The second pulley 77 drives the L-shaped rod 76 to move, and the L-shaped rod 76 drives the unblocking plate 75 to move. When the sliding plate 10 leaves, the unblocking plate 75 will be reset by the spring, thereby realizing the reciprocating unblocking of the drain outlet of the outer shell 2 by the unblocking plate 75. Regular unblocking can prevent poor drainage and avoid blockage. Regular unblocking can reduce corrosion and damage, extend the service life of the pipe, effectively prevent and solve drainage problems, and improve the working efficiency of the equipment.

[0037] Working principle: While cleaning the condensate at the bottom of the condenser plate 12, the sliding plate 10 drives the squeezing plate 74 to work with the trapezoidal plate 73 to squeeze the sponge plate 11 from both above and below. Squeezing the sponge can more effectively remove the water inside the sponge and avoid water residue, thereby improving cleaning efficiency. While pressurizing the condensate, the sliding plate 10 moves back and forth to drive the unblocking plate 75 to unblock the drain outlet of the outer shell 2. Regular unblocking can prevent poor drainage and blockage. Regular unblocking can also reduce corrosion and damage and extend the service life of the pipe.

[0038] The positioning mechanism 8 includes a support rod 81, which is slidably connected to a moving rod 82 via a spring. A positioning plate 83 is fixedly connected to the side of the moving rod 82 near the fixed bracket 3.

[0039] When the outer casing 2 is being repaired, the staff aligns the repaired outer casing 2 with the corresponding position. At this time, the fixed bracket 3 will drive the positioning plate 83 to move. When the fixed bracket 3 enters the interior of the support rod 81, the moving rod 82 will be reset by the spring in the middle of the support rod 81, thereby driving the positioning plate 83 to reset. This allows the positioning plate 83 to cooperate with the fixed bracket 3 to position the outer casing 2, avoiding equipment offset or instability caused by improper installation. Through the cooperation of the positioning part and the positioning mating part, the chassis and chassis bracket can be pre-positioned, improving the stability and reliability of the installation, and at the same time improving the smoothness of equipment operation.

[0040] A rotating rod 84 is rotatably connected to the inner wall of the unblocking plate 75. Gears 85 are fixedly connected to the front and rear sides of the rotating rod 84. A rotating rod 87 is fixedly connected to the circumferential surface of the rotating rod 84. A rack 86 is fixedly connected to the top of the outer casing 2. The bottom of the casing 1 is fixedly connected to the top of the support rod 81. The positioning plate 83 contacts the top of the fixed bracket 3. The circumferential surface of the gear 85 meshes with the top of the rack 86.

[0041] While clearing the internal drain outlet of the outer casing 2, the reciprocating movement of the clearing plate 75 drives the reciprocating movement of the rotating rod 84, which in turn drives the reciprocating movement of the gear 85. The reciprocating movement of the gear 85 passes through the meshing point between the circumferential surface and the top of the rack 86, thereby causing the gear 85 to rotate. The gear 85 drives the rotating rod 84 to rotate, which in turn drives the rotating rod 87 to rotate, thus cleaning the drain outlet. This process can break up larger impurities and ice blocks in the drain outlet, effectively agitating the water inside and preventing the water from freezing or settling due to stasis, thereby improving drainage efficiency. At the same time, it avoids equipment operation problems caused by poor drainage, thus improving the overall operational stability of the equipment.

[0042] Working principle: When the outer casing 2 is being maintained, the positioning plate 83, in conjunction with the fixed bracket 3, positions the outer casing 2 to prevent equipment displacement or instability caused by improper installation. Through the cooperation of the positioning part and the positioning mating part, the chassis and chassis bracket can be pre-positioned, improving the stability and reliability of the installation, and also enhancing the smoothness of equipment operation. While clearing the internal drain outlet of the outer casing 2, the reciprocating movement of the clearing plate 75 will drive the rotating rod 87 to rotate, thereby cleaning the drain outlet. Larger impurities and ice blocks in the drain outlet can be broken up, effectively agitating the water in the drain outlet and preventing the water from freezing or settling due to stillness, thereby improving drainage efficiency.
