Description

Technical Field

[0001] The present invention relates to the field of air conditioning, and more particularly to a ventilation and exhaust device for an electrical and mechanical installation of an air conditioner. Background Art

[0002] The outdoor unit of an air conditioner is the core power and heat dissipation component of an air conditioning system. Its core task is to dissipate heat absorbed indoors and drive the refrigerant circulation. Its operating principle is based on the vapor compression refrigeration cycle, which consists of four key steps: compression, condensation and heat dissipation, throttling and pressure reduction (usually performed by an expansion valve, which may be in the indoor or outdoor unit), and evaporation (accomplished in the indoor unit).

[0003] The Chinese patent with authorization announcement number CN115875757B discloses an air conditioner outdoor unit and an air conditioner. The heat dissipation duct can increase the air flow in the cavity where the compressor is located, and the exhausted air flow directly flows into the gap between adjacent fins for heat dissipation, thereby ensuring the heat dissipation inside the electronic control box; at the same time, under the action of the collecting cap, the air flow of the condenser will also be guided to the radiator, which can improve the heat dissipation effect of the radiator, while taking into account the internal heat dissipation of the electronic control box and the heat dissipation of the heating elements on the electronic control box, thereby improving the overall heat dissipation effect, avoiding damage to the electronic control box and components due to excessive temperature, and ensuring the normal operation of the entire machine.

[0004] The above method can increase the air flow in the cavity where the compressor is located through the heat dissipation duct. The exhausted air flow directly flows into the gaps between adjacent fins for heat dissipation, thereby ensuring the heat dissipation inside the electronic control box. However, when the fan rotates, dust will enter the fins and reach the gaps between the fins, making it difficult to clean the fins. Workers are required to remove the air conditioner outdoor unit from a high altitude and move it indoors for cleaning, which is a cumbersome process. Summary of the Invention

[0005] In response to the problems existing in the prior art, the purpose of the present invention is to provide a ventilation and exhaust device for an air conditioner electrical installation. By controlling the fan to rotate counterclockwise 30 seconds after starting, the fan generates wind to blow toward the fins, which can blow out dust and other substances attached to the surface of the fins, and effectively prevent the fan from generating suction on the fins when rotating clockwise, and causing dust and other substances attached to the outer surface of the fins to be stuck between the fins, making it too troublesome to clean the fins. The fins can be cleaned every time the air conditioner is turned on, making cleaning more convenient, effectively preventing the need for professionals to remove the outer casing from the outdoors for cleaning, and effectively preventing dust and other substances from adhering to the surface of the fins, resulting in a poor air conditioner usage experience.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

A gear is fixedly connected to the surface of the first rotating column, and a tooth groove is provided at the position of the gear corresponding to the second rotating column.

[0010] Furthermore, the cross-section of the second rotating column in the water spraying part is a right-angled trapezoid, the water spraying part is slidably connected with an extrusion column, and the water spraying part is provided with a first spring welded to the second extension block.

[0011] Furthermore, a flow guide member fixedly connected to the baffle is provided on the top of the water spray member, and a water inlet hole connected to the condenser pipe is opened on the left side of the flow guide member.

[0012] Furthermore, a receiving cavity for receiving condensed water is provided inside the flow guide, a floating plate is slidably connected to the inside of the flow guide, and a connecting rope is connected to the bottom of the floating plate.

[0013] Furthermore, a rotating plate rotatably connected to the accommodating cavity is provided at one end of the connecting rope away from the floating plate, the connection point between the connecting rope and the rotating plate is at the rear side of the center of the rotating plate, and a connecting hole is provided inside the water spraying member at a position corresponding to the rotating plate.

[0014] Furthermore, a guide plate is fixedly connected to the bottom of the shell, and a plurality of longitudinal grooves are provided on the surface of the guide plate. The cross-section of the longitudinal grooves is an arc surface, and a plurality of equally spaced transverse grooves are provided on the surface of the guide plate. Through holes are provided at both ends of the longitudinal grooves at the front side.

[0015] Furthermore, the surface of the first rotating column is located at the mounting position and extends toward the mounting direction to form a first extension block. The bottom of the mounting is provided with an impact mechanism, which includes a movable plate slidably connected to the surface of the mounting.

[0016] Furthermore, the top of the movable plate extends toward the mounting member to form a driving block, a rotating groove for accommodating the rotation of the first extension block is provided inside the mounting member, a rubber block is fixedly connected to the driving block in the direction close to the baffle, a third extension block is fixedly connected to the top of the movable plate, and a second spring welded to the third extension block is provided inside the mounting member.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This solution controls the fan to rotate counterclockwise for 30 seconds after startup, so that the fan generates wind to blow toward the fins, which can blow out dust and other substances attached to the surface of the fins, and effectively prevent the fan from generating suction on the fins when rotating clockwise, causing dust and other substances attached to the outer surface of the fins to be stuck between the fins, making it too troublesome to clean the fins. In addition, the initial fan rotation to blow air toward the fins will not affect the use of the indoor air conditioner. After the air conditioner is turned off, the fan is controlled to rotate counterclockwise again for 30 seconds after turning off, and the dust that reached the surface of the fins during use is blown out of the fin surface again, avoiding dust from adhering to the fin surface for a long time, making it difficult to blow dust off the fins, and making it more convenient to clean the dust on the fin surface. The fins can be cleaned every time the air conditioner is turned on, making cleaning more convenient, effectively preventing the need for professionals to remove the outer casing from the outdoors for cleaning, and effectively preventing dust and other substances from adhering to the fin surface, resulting in a poor air conditioner usage experience.

[0019] 2. In this solution, when the second rotating column rotates, the inclined part of the second rotating column can squeeze the extrusion column, and the extrusion column is squeezed by the second rotating column and moves inside the water spray part. By injecting water into the water spray part, the extrusion column can squeeze the water. The water spray part is fixedly connected to an atomizer on one side close to the fin. The squeezed water reaches the position of the atomizer, and the water is atomized and discharged through the atomizer. The atomized water cleans the surface of the fin, which has a better cleaning effect on the fin. At the same time, the fin is cooled during the fin cleaning process, so that the refrigerant in the fin is cooled faster, which saves energy and has a better air conditioning effect. The water spraying time is when the air conditioner is in use. At this time, the fan rotates clockwise and it is difficult to clean the fins. At this time, the fins are cleaned by spraying water, so that the fins are always in a cleaned state during use, which makes it more convenient to clean the fins and more convenient for the outside air to pass through the fins to reach the inside of the shell, thereby achieving a better heat exchange effect on the fins.

[0020] The buoyancy control device of described floating plate is to be continued to be continued to the buoyancy control device, and the buoyancy control device of described floating plate is continued to be continued to the buoyancy control device, and the buoyancy control device is continued to be continued to the buoyancy control device, so that the buoyancy control device can be continued to the buoyancy control device.

[0021] 4. This solution guides the condensed water in this part through the longitudinal groove. The cross-section of the longitudinal groove is an arc surface, which is convenient for guiding the condensed water to the two ends of the longitudinal groove. The transverse groove guides the condensed water on both sides of the longitudinal groove. The condensed water reaches the inside of the transverse groove. The cross-section of the guide plate is a right triangle, and the inclined surface is directed to the fin, which is convenient for guiding the condensed water in the transverse groove, so that the condensed water follows the transverse groove to the front side of the guide plate, which has a better effect on collecting the condensed water. Finally, the condensed water reaches the inside of the longitudinal groove on the front side. The condensed water reaches the through holes on both sides of the longitudinal groove, and the through holes are connected to the outside world, which is convenient for the condensed water to be discharged from the shell to the outside, which has a better effect on the discharge of the condensed water and effectively prevents the condensed water from remaining inside the shell. The dust washed down by the condensed water will also be discharged from the through holes along the condensed water, which has a better effect on the discharge of the cleaned dust.

[0022] 5. This solution uses a moving plate to carry a rubber block to hit the baffle, causing the baffle to vibrate due to the impact. By transferring the vibration to the fins, the fins vibrate, which facilitates the shaking off of dust on the surface of the fins, and effectively cleans the fins with multiple layers of thermal conductive plates. Different fins can be cleaned, and the effect of cleaning the fins is better. During the movement of the moving plate, the third extension block squeezes the second spring, causing the second spring to change from a naturally stretched state to a taut state, making it convenient for the moving plate to repeatedly carry the rubber block to hit the baffle, and the cleaning effect of the fins is better.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] See also Figures 1 to 9, a ventilation and exhaust device for an air conditioner electrical installation includes a shell 1, a fin 11 for refrigerant heat exchange is fixedly connected to the front side of the shell 1, a mounting plate 15 is fixedly connected to the inside of the shell 1, a bidirectional motor 14 is fixedly connected to the inside of the mounting plate 15, a fan 13 for blowing out hot air in the shell 1 is fixedly connected to the front output shaft end of the bidirectional motor 14, a PCL controller 16 is fixedly connected to the front surface of the mounting plate 15, the PCL controller 16 is electrically connected to the fan 13, and the rotation of the fan 13 is controlled by the PCL controller 16. By controlling the fan 13 to rotate counterclockwise 30 seconds after starting, the fan 13 generates wind force to blow in the direction of the fin 11, which can blow out dust and other substances attached to the surface of the fin 11, and effectively prevent the fan 13 from rotating against the fin 11 when the fan 13 rotates clockwise. The blades 11 generate suction, which sticks the dust and other substances on the outer surface of the fins 11 between the fins 11, making it too troublesome to clean the fins 11, and the initial rotation of the fan 13 to blow air to the fins 11 will not affect the use of the indoor air conditioner. After the air conditioner is turned off, the fan 13 is controlled to rotate counterclockwise again 30 seconds after it is turned off, and the dust that reaches the surface of the fins 11 during use is blown out of the surface of the fins 11 again, avoiding the dust from adhering to the surface of the fins 11 for a long time, making it difficult to blow the dust away from the fins 11, and making it more convenient to clean the dust on the surface of the fins 11. The fins 11 can be cleaned every time the air conditioner is turned on, making cleaning more convenient, effectively preventing the need for professionals to remove the outer shell 1 from the outdoors for cleaning, and effectively preventing dust and other substances from adhering to the surface of the fins 11, resulting in a poor air conditioner experience.

[0036] like Figures 1 to 9As shown, the interior of the shell 1 is fixedly connected to a baffle 12, and a cleaning and cooling mechanism 2 is provided on the right side of the baffle 12. The cleaning and cooling mechanism 2 includes a mounting member 22 fixedly connected to the baffle 12, and the front output shaft end of the bidirectional motor 14 is fixedly connected to a first rotating column 141 that passes through the mounting member 22. The output shaft of the front side is driven to rotate by the bidirectional motor 14, and the first rotating column 141 can be driven to rotate. The front side of the mounting member 22 is fixedly connected to a water spraying member 23, and the rear side of the water spraying member 23 is internally rotatably connected to a second rotating column 232 that passes through the mounting member 22. The first rotating column 141 rotates, and a gear 142 is fixedly connected to the surface of the first rotating column 141. The rotation of the first rotating column 141 can control the rotation of the gear 142, so that the rotation of the gear 142 is more convenient. The second rotating column 232 is provided with a tooth groove 237 at the position corresponding to the gear 142. The rotation of the gear 142 can drive the tooth groove 237 to rotate, so that the tooth groove 237 rotates with the second rotating column 232, making the rotation of the second rotating column 232 more convenient. The cross-section of the second rotating column 232 in the water spraying part 23 is a right-angled trapezoid. The rotation of the second rotating column 232 in the water spraying part 23 can be controlled by rotating the second rotating column 232 outside the water spraying part 23. The squeezing column 236 is slidably connected to the inside of the water spraying part 23. When the second rotating column 232 rotates, the inclined part of the second rotating column 232 can squeeze the squeezing column 236. The squeezing column 236 is squeezed by the second rotating column 232 and moves inside the water spraying part 23. 23, the interior of the water injection means 236 can be squeezed to squeeze the water, the water spray member 23 is fixedly connected to the side of the fin 11 close to the atomizer 231, the squeezed water reaches the position of the atomizer 231, the water is atomized and discharged through the atomizer 231, the atomized water cleans the surface of the fin 11, the cleaning effect of the fin 11 is better, and while the fin 11 is being cleaned, the fin 11 is cooled, so that the refrigerant in the fin 11 is cooled faster, so that the air conditioner saves energy and has a better air conditioning effect. The surface of the extrusion column 236 extends toward the inner wall of the water spray member 23 to form a second extension block 234, and the second extension block 234 moves within the inner wall of the water spray member 23. The extrusion column 236 is restricted by the second extension block 234, so that the movement of the extrusion column 236 is faster. For convenience, the interior of the water spraying member 23 is provided with a first spring 233 welded with the second extension block 234. When the squeezing column 236 moves with the second extension block 234, the second extension block 234 moves to squeeze the first spring 233, so that the first spring 233 changes from the original naturally stretched state to the tight state, so that the squeezing column 236 can return to the original position under the action of the first spring 233, and the squeezing column 236 can move repeatedly to achieve the effect of repeatedly spraying water to clean and cool the fins 11. In addition, when the air conditioner is used, the fan 13 rotates clockwise and it is difficult to clean the fins 11. At this time, the fins 11 are cleaned by spraying water, so that the fins 11 are always in a clean state during use.This makes it easier to clean the fins 11 and allows the outside air to pass through the fins 11 and reach the interior of the housing 1, resulting in a better heat exchange effect on the fins 11.

[0037] like Figures 1 to 9 As shown, the top of the water spraying member 23 is provided with a guide member 21 fixedly connected to the baffle 12. The condensation pipe in the shell 1 passes through the baffle 12 to reach the position of the guide member 21. The left side of the guide member 21 is provided with a water inlet hole 211 connected to the condensation pipe, so that the condensed water can reach the inside of the guide member 21 through the condensation pipe during the operation of the air conditioner. The inside of the guide member 21 is provided with a accommodating chamber 212 for accommodating condensed water. The inside of the guide member 21 is slidably connected with a floating plate 213. As the amount of condensed water in the guide member 21 increases, the floating plate 213 always floats on the surface of the condensed water. The inner wall of the guide member 21 is provided with a limiting groove 214 for accommodating the sliding connection of the floating plate 213. The part of the floating plate 213 in the limiting groove 214 moves in the limiting groove 214, so that the movement of the floating plate 213 is more stable, preventing the floating plate 213 from shaking and making it difficult to float on the surface of the condensed water. The bottom of the floating plate 213 is connected with a connecting rope 215. When floating, the floating plate 213 pulls the connecting rope 215. The end of the connecting rope 215 away from the floating plate 213 is provided with a rotating plate 216 that is rotatably connected to the accommodating chamber 212. The connecting rope 215 is pulled by the floating plate 213 and the rotating plate 216 is pulled. The connection point between the connecting rope 215 and the rotating plate 216 is at the rear side of the center of the rotating plate 216, which facilitates the rotation of the rotating plate 216 after being pulled, making the rotation of the rotating plate 216 more convenient. The internal part of the water spraying part 23 corresponds to the rotating plate 216. A connecting hole 235 is provided at the position of the plate 216, and the guide member 21 and the water spray member 23 are connected to the connecting hole 235 through the circular hole of the rotating plate 216, so that the condensed water in the guide member 21 is stored to a certain extent and then flows into the inside of the water spray member 23, so that the water spray member 23 can spray the condensed water to cool and clean the fins 11, which has a better cooling and cleaning effect on the fins 11, and is more convenient for the outside air to pass through the fins 11 to reach the inside of the shell 1, thereby having a better heat exchange effect on the fins 11.

[0038] like Figures 1 to 9As shown, the bottom of the shell 1 is fixedly connected with a guide plate 3, and a plurality of longitudinal grooves 31 are provided on the surface of the guide plate 3. The condensed water sprayed by the water spraying member 23 will remain in the interior of the shell 1. This portion of the condensed water reaches the top of the guide plate 3. Since the longitudinal grooves 31 are provided inside the guide plate 3, the condensed water of this portion is guided by the longitudinal grooves 31. The cross section of the longitudinal grooves 31 is an arc surface, which is convenient for guiding the condensed water to the two ends of the longitudinal grooves 31, making the condensed water guiding more convenient. The surface of the guide plate 3 is provided with a plurality of equally spaced transverse grooves 32 in the transverse direction. The transverse grooves 32 guide the condensed water on both sides of the longitudinal grooves 31. The condensed water reaches the interior of the transverse grooves 32. The cross section of the guide plate 3 is The right triangle, with the inclined surface pointing to the fin 11, is convenient for guiding the condensed water in the transverse groove 32, so that the condensed water follows the transverse groove 32 to the front side of the guide plate 3, which has a better collection effect on the condensed water. Through holes 33 are provided at both ends of the frontmost longitudinal groove 31, and finally the condensed water reaches the interior of the frontmost longitudinal groove 31. The condensed water reaches both sides of the longitudinal groove 31 and enters the through holes 33, and the through holes 33 are connected to the outside world, which is convenient for the condensed water to be discharged from the shell 1 to the outside, which has a better discharge effect on the condensed water and effectively prevents the condensed water from remaining inside the shell 1. The dust washed down by the condensed water will also be discharged from the through holes 33 along the condensed water, which has a better discharge effect on the cleaned dust.

[0039] like Figures 1 to 9As shown, the surface of the first rotating column 141 is at the position of the mounting member 22 and extends toward the mounting member 22 to form a first extending block 143. The first extending block 143 can be controlled to rotate inside the mounting member 22 by rotating the first rotating column 141, so that the first extending block 143 can rotate more conveniently. The bottom of the mounting member 22 is provided with an impact mechanism 4, and the impact mechanism 4 includes a moving plate 41 slidably connected to the surface of the mounting member 22. The top of the moving plate 41 extends toward the mounting member 22 to form a driving block 45. The driving block 45 is squeezed during the rotation of the first extending block 143, and the driving block 45 is squeezed and moved. The driving block 45 moves in the direction of the baffle 12 with the moving plate 41. The interior of the mounting member 22 is provided with a rotating groove 221 that accommodates the rotation of the first extending block 143, so that the first extending block 143 can rotate more conveniently in the rotating groove 221. The driving block 4 A rubber block 44 is fixedly connected in the direction close to the baffle 12. The movable plate 41 carries the rubber block 44 to impact the baffle 12, causing the baffle 12 to vibrate by the impact. By transmitting the vibration to the fins 11, the fins 11 vibrate, which facilitates the shaking off of dust on the surface of the fins 11, effectively cleaning the fins 11 with multiple layers of thermal conductive sheets stacked together. Different fins 11 can be cleaned, and the cleaning effect of the fins 11 is better. A third extension block 42 is fixedly connected to the top of the movable plate 41. A second spring 43 welded to the third extension block 42 is provided inside the mounting member 22. When the movable plate 41 moves, the third extension block 42 squeezes the second spring 43, causing the second spring 43 to change from a naturally extended state to a taut state, making it convenient for the movable plate 41 to repeatedly carry the rubber block 44 to impact the baffle 12, thereby improving the cleaning effect of the fins 11.
