Description

Technical Field

[0001] This invention belongs to the field of air conditioning equipment technology, specifically relating to a refrigeration energy-saving air conditioning equipment and its control method. Background Technology

[0002] With the escalating global energy crisis and heightened environmental awareness, the energy efficiency and operational effectiveness of air conditioning equipment have become core issues of concern in the industry. As a key component of the refrigeration system, the outdoor unit of an air conditioner directly determines its energy consumption level through the heat dissipation performance of its internal condenser. However, in actual operation, dust easily accumulates on the condenser surface. According to industry statistics, when the dust accumulation on the condenser surface reaches 0.2mm, its heat dissipation efficiency decreases by 15%-30%, leading to increased compressor load and a power consumption increase of over 20%.

[0003] Problems with existing technology: Currently, during long-term use, dust and other impurities easily accumulate on the surface of the condenser of the outdoor unit of an air conditioner, leading to a decrease in heat dissipation efficiency, which in turn affects the cooling effect and increases energy consumption. Traditional cleaning methods mostly rely on manual labor, which is not only labor-intensive and ineffective, but also poses a high risk of falling, especially for air conditioner outdoor units installed at high altitudes. Furthermore, the condensate and rainwater generated during air conditioner use are often not effectively utilized, resulting in water waste. Summary of the Invention

[0004] The purpose of this invention is to provide a refrigeration and energy-saving air conditioning equipment and its control method, which can solve the problems of easy dust accumulation in the condenser affecting heat dissipation, inconvenient cleaning, water waste, and insufficient safety during cleaning in the prior art, and achieve the goals of improving the heat dissipation efficiency of the condenser, automatically cleaning the condenser, saving water resources, and improving cleaning safety.

[0005] The specific technical solution adopted by this invention is as follows: A cooling and energy-saving air conditioning device includes an outdoor unit housing and a condenser disposed therein. The outdoor unit housing is provided with a moving mechanism and a nozzle mechanism. The nozzle mechanism is assembled into the outdoor unit housing through the moving mechanism. The moving mechanism is used to drive the nozzle body on the nozzle mechanism to perform large-range movement and small-range reciprocating movement. The top of the outdoor unit housing is provided with a collection mechanism for collecting the air conditioning indoor unit and rainwater.

[0006] The motor drives the first lead screw of the moving mechanism to rotate, thereby driving the nozzle mechanism to move over a wide range. When it moves to an area with a lot of dust accumulation in the condenser, it stops. At the same time, the motor drives the shaft to rotate, and the shaft drives the reciprocating lead tube to rotate, thereby driving the nozzle mechanism to perform a reciprocating moving rinsing operation on the area with a lot of dust accumulation. A partition is provided inside the outer casing above the condenser. A shaft is rotatably installed through the bottom of the partition and on both sides outside the condenser. The two shafts are connected by a belt drive mechanism. The outer wall of the shaft is fitted with a reciprocating wire tube that can slide up and down, and a second mounting plate is threaded between the outer walls of the two reciprocating wire tubes.

[0007] A first mounting plate is rotatably installed between the tops of the two reciprocating tubings, and a first lead screw threadedly connected to the first mounting plate is rotatably installed through the bottom of the partition plate. A linkage unit is provided between the first lead screw and one of the shafts to enable the first lead screw to be connected or disconnected from one of the shafts.

[0008] A water tank is located at the bottom of the outer casing and below the condenser. A drain trough is located on the top of the water tank to collect wastewater generated during rinsing the condenser.

[0009] The second mounting plate has multiple downward-sloping insertion slots equidistantly spaced on the side facing the condenser. The insertion slots are slidably connected to the nozzle body. An hourglass groove is provided on one side of the nozzle body. A water pump connected to the water tank is installed on the inner bottom of the outdoor unit housing. The water pump is connected to the insertion slots on the second mounting plate through a telescopic hose.

[0010] When the nozzle mechanism washes the condenser, the water pressure pushes one end of the nozzle body through the two elastic semi-circular rubber sheets set at the end of the insertion slot; After the rinsing operation is completed, the elastic force generated by the first spring pushes the nozzle body to move in the opposite direction and retract into the insertion slot. The insertion slot is sealed by two elastic semi-circular rubber sheets. The end of the nozzle body is fixed with a second limiting ring that is slidably connected to the insertion slot. The end of the insertion slot is fixed with a first limiting ring that is slidably connected to the nozzle body. A first spring is provided between the outer walls of the first limiting ring and the second limiting ring and sleeved on the outer wall of the nozzle body.

[0011] The outer wall of the second mounting plate is provided with elastic semi-circular rubber sheets for sealing the interlocking grooves in an alternating manner.

[0012] The top of the collection mechanism is provided with a mounting base, and a collection groove is provided on one side of the top of the mounting base. The bottom of the collection groove is inclined to one side. The top of the mounting base is provided with a sloping panel, and multiple filter holes are provided on one side of the top of the sloping panel directly above the collection groove. The bottom of the mounting base is provided with a return pipe that communicates with the bottom end of the sloping part of the collection groove.

[0013] Both sides of the inclined panel are fixed with side plates, and a baffle plate is rotatably installed between the outer walls of the two side plates. The baffle plate, the inclined panel, and the two side plates form a water storage tank. A reset unit that is rotatably connected to the baffle plate is rotatably installed on one side of the side plate. When the filter holes are clogged, rainwater accumulates in the storage tank. When the collected rainwater reaches a certain weight, its gravity pushes the baffle plate open, allowing the water to carry impurities out of the storage tank.

[0014] The mounting base has a mounting slot on top and on one side of the collection tank. Inside the mounting slot, a battery, a controller, and a circuit breaker are arranged in sequence. The photovoltaic panel, which is electrically connected to the battery, is located on top of the inclined panel and on one side of the filter hole. The controller is electrically connected to the battery, the circuit breaker, and the motor.

[0015] A control method for an energy-saving air conditioning device includes the following steps: S1, When the sensor detects that the dust in the condenser has reached the set value, it sends a signal to the controller; S2, the controller cuts off the power supply to the outdoor unit of the air conditioner through the circuit breaker; S3, start the motor and water pump, the shaft drives the reciprocating wire tube to rotate, so that the second mounting plate drives the nozzle body to move back and forth in a small range to wash the dust accumulation area. The electric push rod drives the sleeve to move, and through the cooperation of the insertion guide groove and the insertion guide block, the first screw is driven to rotate through the worm gear-worm wheel transmission, so that the first mounting plate drives the reciprocating wire tube to move in a large range to switch the washing area. S4, after rinsing is completed, the water pump stops working, the first spring pushes the nozzle body back into the insertion slot, and the elastic semi-circular rubber sheet seals; S5, the motor and electric push rod reset, the controller controls the circuit breaker to close, and the power supply to the outdoor unit of the air conditioner is restored.

[0016] The technical effects achieved by this invention are as follows: This invention can automatically detect and clean the condenser, ensuring heat dissipation efficiency and saving energy. By using sensors to detect dust on the condenser, the cleaning program is automatically started when the dust reaches a set value. This effectively avoids the problem of reduced heat dissipation efficiency and increased power consumption caused by dust accumulation, ensuring that the condenser always maintains a good heat dissipation state, improving air conditioning cooling efficiency and reducing energy consumption.

[0017] This invention effectively collects and utilizes rainwater and condensate, conserving water resources. The collection mechanism can collect rainwater and condensate generated by the indoor unit of an air conditioner for cleaning the condenser, reducing dependence on tap water and saving water resources.

[0018] This invention provides a safe and reliable condenser cleaning process with a high degree of automation, reducing manual labor intensity and risks. During cleaning, the controller cuts off the power supply to the outdoor unit of the air conditioner via a circuit breaker, ensuring cleaning safety. The entire cleaning process is completed automatically without manual intervention, especially avoiding the risk of falls from heights and reducing the labor intensity of workers.

[0019] The moving mechanism of this invention can drive the nozzle body on the nozzle mechanism to perform large-range movement and small-range reciprocating movement, which can perform comprehensive and targeted cleaning of the condenser, improve the cleaning effect, ensure the heat dissipation efficiency of the condenser, and reduce air conditioning energy consumption.

[0020] In this invention, elastic semi-circular rubber sheets are symmetrically arranged at the top and bottom of the insertion slot in the nozzle mechanism to seal the insertion slot, which facilitates the protection of the nozzle body and prevents dust from clogging the nozzle body when it is not used for a long time, thereby improving the practicality and performance of the equipment. The first and second limiting rings can effectively increase the sealing of the sliding connection between the nozzle body and the insertion slot. The hourglass groove can push the nozzle body to move, which facilitates the normal operation of the equipment. After rinsing, the nozzle body can retract into the insertion slot and be sealed by the elastic semi-circular rubber sheets.

[0021] This invention features a collection mechanism that can collect rainwater and condensate from the indoor unit of an air conditioner. The collected water is stored in a water tank and used to flush the condenser, saving water resources and conforming to the concept of energy conservation. When the filter holes are blocked, the baffle in the collection mechanism can open under the action of gravity of the rainwater, allowing the water flow to carry away impurities and preventing impurities from clogging the filter holes, thus ensuring the normal operation of the collection work.

[0024] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0025] like Figures 1-6 As shown, a cooling and energy-saving air conditioning device includes an outdoor unit housing 1 and a condenser 2 disposed inside it. The outdoor unit housing 1 is provided with a moving mechanism 5 and a nozzle mechanism 6. The nozzle mechanism 6 is assembled into the outdoor unit housing 1 through the moving mechanism 5. The moving mechanism 5 is used to drive the nozzle body 62 on the nozzle mechanism 6 to perform large-range movement and small-range reciprocating movement. The top of the outdoor unit housing 1 is provided with a collection mechanism 7 for collecting the air conditioning indoor unit and rainwater.

[0026] Inside the outdoor unit housing 1, above the condenser 2, there is a partition 4. A shaft 51 is rotatably mounted through the bottom of the partition 4 and on both sides of the condenser 2. The two shafts 51 are connected by a belt drive mechanism 57. A reciprocating tube 53 that can slide up and down is fitted onto the outer wall of the shaft 51. A second mounting plate 54 is threaded between the outer walls of the two reciprocating tubes 53. A motor 56 connected to one of the shafts 51 is located at the top inner part of the outdoor unit housing 1. Multiple guide rails are provided on the outer surface of the shaft 51. A matching groove that slides with the guide rails is provided on the inner side of the reciprocating tube 53, making the movement of the reciprocating tube 53 more stable and allowing the shaft 51 to rotate, thus driving the reciprocating tube 53 to rotate. A first mounting plate 52 is rotatably installed between the tops of the two reciprocating tubing 53, and a first lead screw 55, which is threadedly connected to the first mounting plate 52, is rotatably installed through the bottom of the partition plate 4; a linkage unit is provided between the first lead screw 55 and one of the shafts 51 to realize the first lead screw 55 and one of the shafts 51 to be connected or disconnected. The linkage unit includes an electric push rod 514. The output shaft of the electric push rod 514 is fixed with a connecting plate 513. A sleeve 512 is rotatably mounted through one side of the connecting plate 513. Mounting shafts 59 are inserted into both ends of the sleeve 512. A support ear 58 rotatably connected to the mounting shaft 59 is fixed to the top of the partition plate 4. A worm gear 510 is fixed to one end of the mounting shaft 59. A worm wheel 511 that cooperates with the worm gear 510 is fixed to one of the shafts 51 and the first lead screw 55. A limit slider 516 is fixed inside the sleeve 512 at one end of one mounting shaft 59. A limit groove 515 that slidably connects with the limit slider 516 is provided on the inner side of the sleeve 512. An insertion guide block 517 is fixed inside the sleeve 512 at one end of the other mounting shaft 59. An insertion guide groove 518 that cooperates with the insertion guide block 517 is provided on the inner side of the sleeve 512.

[0027] According to the above structure, the motor 56 is started, which drives the shaft 51 to rotate. The shaft 51 drives the reciprocating wire tube 53 to rotate, and the reciprocating wire tube 53 drives the second mounting plate 54 to move up and down in a small range. This, in turn, drives the nozzle body 62 to move up and down in a small range, allowing the condenser 2 in areas with more dust to be repeatedly rinsed. After rinsing, the electric push rod 514 is started, which drives the sleeve 512 to move. The sleeve 512 drives the insertion guide groove 518 to cooperate with the insertion guide block 517. Through the meshing of the worm gear 510 and the worm wheel 511, the first lead screw 55 is driven to move. The first lead screw 55 drives the first mounting plate 52 to move. The first mounting plate 52 drives the reciprocating wire tube 53 to move up and down in a large range along the shaft 51, which is used to move the nozzle body 62 to the next area to perform rinsing operations on the condenser 2.

[0028] like Figure 3As shown, a water tank 3 is provided at the bottom of the outer casing 1 and below the condenser 2. A drain trough 13 is provided on the top of the water tank 3 to collect the wastewater generated from rinsing the condenser 2. A discharge port is provided on one side of the drain trough 13.

[0029] Based on the above structure, the water tank 3 is designed to facilitate the storage of condensate and rainwater; the drain trough 13 is integrated with the water tank 3, making the structure more compact. The drain trough 13 facilitates the collection and discharge of wastewater generated from rinsing the condenser 2, increasing the practicality of the equipment.

[0030] like Figures 7-8 As shown, the second mounting plate 54 has multiple horizontally equidistant insertion slots 61 inclined downward at 15 degrees on the side facing the condenser 2. The insertion slots 61 are slidably connected to the nozzle body 62. An hourglass groove 63 is provided on one side of the nozzle body 62. A water pump 68 connected to the water tank 3 is provided at the bottom of the outer casing 1. The water pump 68 is connected to the insertion slots 61 on the second mounting plate 54 through a telescopic hose. A second limiting ring 65 is fixed at the end of the nozzle body 62 and is slidably and sealingly connected to the insertion slots 61. A first limiting ring 64 is fixed at the end of the insertion slots 61 and is slidably and sealingly connected to the nozzle body 62. A first spring 66 is provided between the outer walls of the first limiting ring 64 and the second limiting ring 65 and is sleeved on the outer wall of the nozzle body 62. Elastic semi-circular rubber sheets 67 that seal the insertion slots 61 are staggered on the outer wall of the second mounting plate 54.

[0031] According to the above structure, the elastic semi-circular rubber sheets 67 are symmetrically arranged at the top and bottom of the insertion groove 61 to seal the insertion groove 61, which facilitates the protection of the nozzle body 62 and prevents dust from clogging the nozzle body 62 when not in use for a long time, thus improving practicality and performance. The first limiting ring 64 and the second limiting ring 65 can effectively increase the sealing of the sliding connection between the nozzle body 62 and the insertion groove 61. The hourglass groove 63 includes two symmetrical funnel-shaped grooves, and a connecting pipe is connected between the small-diameter ports on the two funnel-shaped grooves to increase the water resistance and push the nozzle body 62 to move, so that the water outlet end of the nozzle body 62 extends out of the insertion groove 61 and passes through the two elastic semi-circular rubber sheets 67, which facilitates the normal operation of the equipment. When the rinsing operation is completed, the elastic force generated by the first spring 66 pushes the nozzle body 62 to move in the opposite direction and retract into the insertion groove 61, and the two elastic semi-circular rubber sheets 67 seal the insertion groove 61. like Figure 1 , Figure 2 , Figure 3 , Figure 9 and Figure 10As shown, the top of the collection mechanism 7 is provided with a mounting base 71, and a collection trough 72 is opened on one side of the top of the mounting base 71. The bottom of the collection trough 72 is inclined to one side. The top of the mounting base 71 is provided with a sloping panel 73. Multiple filter holes 75 are opened on one side of the top of the sloping panel 73 directly above the collection trough 72 to facilitate the filtration of collected rainwater. The bottom of the mounting base 71 is provided with a return pipe 711 that communicates with the bottom end of the sloping part of the collection trough 72, so that the water in the collection trough 72 can enter the water tank 3 by gravity without the need for other power sources. A collection pipe 15 that communicates with the collection trough 72 is provided on one side of the mounting base 71 for connecting to an external condensate pipe to collect condensate from the indoor unit of the air conditioner. Side plates 74 are fixed on both sides of the inclined panel 73. A baffle plate 76 is rotatably installed between the outer walls of the two side plates 74. The baffle plate 76, the inclined panel 73, and the two side plates 74 form a water storage tank. A reset unit that is rotatably connected to the baffle plate 76 is rotatably installed on one side of the side plate 74. An overflow pipe 14 is provided through one side of the water tank 3 so that excess water can be discharged after the water tank 3 is full. The reset unit includes a mounting tube 77 rotatably connected to the side plate 74. A plug rod 78 rotatably connected to the baffle plate 76 is inserted into the mounting tube 77. One end of the plug rod 78 is provided with a limit block 79 inside the mounting tube 77. A second spring 710 fixed inside the mounting tube 77 is provided on one side of the limit block 79.

[0032] According to the above structure, when collecting rainwater, the falling rainwater is carried by gravity and slides down the inclined panel 73 to the filter hole 75, passes through the filter hole 75 into the collection tank 72, and then enters the water tank 3 through the return pipe 711 for collection. In addition, the condensate produced by the indoor unit of the air conditioner also enters the collection tank 72 through the collection pipe 15, and finally enters the water tank 3 for collection. An overflow pipe 14 is provided on one side of the water tank 3. When the water tank 3 is full, the excess water is discharged through the overflow pipe 14, which increases the practicality of the equipment. When the filter hole 75 is blocked, rainwater accumulates in the water storage tank. When the rainwater collects a certain weight, its gravity pushes the baffle plate 76 to open, allowing the water to carry impurities out of the water storage tank. Then, the elastic force of the second spring 710 drives the plug rod 78 to reset. The plug rod 78 pulls the baffle plate 76 to seal and fit with the two side plates 74 and the inclined plate 73, facilitating the next normal use of the equipment. This structure is simple and avoids impurities from clogging the filter hole 75.

[0033] like Figure 2As shown, a mounting slot 9 is provided on the top of the mounting base 71 and on one side of the collection tank 72. Inside the mounting slot 9, a storage battery 10, a controller 11, and a circuit breaker 12 are arranged in sequence. A photovoltaic panel 8 electrically connected to the storage battery 10 is provided on the top of the inclined panel 73 and on one side of the filter hole 75. The controller 11 is electrically connected to the storage battery 10, the circuit breaker 12, the motor 56, and the water pump 68. Multiple sensors for detecting dust are arranged in an equidistant array on the condenser 2. The sensors are electrically connected to the controller 11. The sensors are optical dust sensors of model GP2Y1014AU0F.

[0034] Based on the above structure, the battery 10 provides power to the controller 11, and the photovoltaic panel 8 uses solar energy to charge the battery 10, which is energy-saving and environmentally friendly. The circuit breaker 12 cuts off the power supply to the outdoor unit of the air conditioner when rinsing the condenser 2, improving the safety of rinsing the condenser 2. After rinsing, the controller 11 controls the circuit breaker 12 to close and reconnect the power supply to the outdoor unit of the air conditioner. The sensor is used to detect dust on the condenser 2. When the dust reaches a set value, the detection signal is transmitted to the controller 11. The controller 11 first disconnects the power supply to the outdoor unit of the air conditioner through the circuit breaker 12, and then controls the motor 56 and the water pump 68 to work, thereby rinsing the condenser 2. The electrical connection of the equipment is relatively complete, which facilitates automatic rinsing of the condenser 2, improves the cleaning efficiency of the condenser 2, reduces the labor intensity of the workers, and increases the practicality of the equipment.

[0035] Working principle: When the sensor on the condenser 2 detects that the dust reaches the set value, the sensor transmits the detection signal to the controller 11. The controller 11 first disconnects the power supply of the outdoor unit of the air conditioner through the circuit breaker 12 to ensure safety during rinsing. Then, the controller 11 controls the motor 56 and the water pump 68 to work. The water pump 68 delivers the water in the water tank 3 to the insertion slot 61 through the telescopic hose. When the water flows through the hourglass groove 63 on one side of the nozzle body 62, the hourglass groove 63 includes two symmetrical funnel-shaped grooves. The small-diameter ports on the two funnel-shaped grooves are connected by a connecting pipe, which increases the water resistance, thereby pushing the nozzle body 62 to move. This causes the water outlet end of the nozzle body 62 to extend out of the insertion slot 61 and pass through the two elastic semi-circular rubber sheets 67 for rinsing. Motor 56 drives shaft 51 to rotate. Under the action of guide rail on the outer surface of shaft 51 and mating groove on the inner side of reciprocating wire tube 53, shaft 51 drives reciprocating wire tube 53 to rotate. Reciprocating wire tube 53 drives second mounting plate 54 to move up and down in a small range, thereby driving nozzle body 62 to move up and down in a small range, which can repeatedly rinse condenser 2 in areas with more dust. After one area is rinsed, the controller 11 controls the electric push rod 514 to start. The output shaft of the electric push rod 514 drives the connecting plate 513 to move. The connecting plate 513 drives the sleeve 512 to move. The sleeve 512 drives the insertion guide groove 518 to cooperate with the insertion guide block 517. At this time, under the meshing action of the worm 510 and the worm wheel 511, the rotation of the shaft 51 drives the first lead screw 55 to rotate. The first lead screw 55 drives the first mounting plate 52, which is threaded to it, to move. The first mounting plate 52 drives the reciprocating thread tube 53 to move up and down a large range along the shaft 51, thereby driving the nozzle body 62 to move to the next area to perform rinsing operation on the condenser 2. The wastewater generated during rinsing is collected through the drain trough 13 and discharged from the discharge port. After rinsing is completed, the controller 11 controls the motor 56 and water pump 68 to stop working. After the water flow stops, the elastic force generated by the first spring 66 pushes the nozzle body 62 to move in the opposite direction and retract into the insertion slot 61. The insertion slot 61 is sealed by two elastic semi-circular rubber sheets 67 to prevent dust from entering. At the same time, the controller 11 controls the circuit breaker 12 to close, connecting the working power supply of the air conditioner outdoor unit, and the air conditioner works normally. During the rainwater collection process, the falling rainwater slides down the inclined panel 73 by gravity to the filter hole 75, passes through the filter hole 75 into the collection tank 72, and then enters the water tank 3 through the return pipe 711 for collection. In addition, the condensate produced by the indoor unit of the air conditioner also enters the collection tank 72 through the collection pipe 15, and finally enters the water tank 3 for collection. When the water tank 3 is full, the excess water is discharged through the overflow pipe 14. When the filter hole 75 is blocked, rainwater accumulates in the water storage tank. When the rainwater collects a certain weight, its gravity pushes the baffle plate 76 to open, allowing the water to carry impurities out of the water storage tank. Then, under the elastic force of the second spring 710, the limit block 79 drives the plug rod 78 to reset. The plug rod 78 pulls the baffle plate 76 to seal and fit with the two side plates 74 and the inclined plate 73, facilitating the next normal use of the equipment. The photovoltaic panel 8 uses solar energy to charge the battery 10, which in turn provides power to the controller 11, circuit breaker 12, motor 56, and water pump 68, thus saving energy.

[0036] A control method for an energy-saving air conditioning device includes the following steps: S1: The sensor detects dust on the condenser 2. When the dust reaches the set value, it transmits the detection signal to the controller 11. S2: Controller 11 first disconnects the power supply to the outdoor unit of the air conditioner through circuit breaker 12; S3: Controller 11 controls the operation of motor 56 and water pump 68. Water pump 68 delivers water from water tank 3 to insertion slot 61 through telescopic hose. When the water flows through hourglass slot 63, it generates resistance and pushes the nozzle body 62 to move, so that the water outlet end of nozzle body 62 extends out of insertion slot 61 and passes through two elastic semi-circular rubber sheets 67. Motor 56 drives shaft 51 to rotate, shaft 51 drives reciprocating wire tube 53 to rotate, reciprocating wire tube 53 drives second mounting plate 54 to move up and down in a small range, thereby driving nozzle body 62 to move up and down in a small range, repeatedly rinsing the condenser 2 in areas with more dust. After rinsing one area, the controller 11 controls the electric push rod 514 to start. The electric push rod 514 drives the sleeve 512 to move. The sleeve 512 drives the insertion guide groove 518 to cooperate with the insertion guide block 517. Through the meshing of the worm gear 510 and the worm wheel 511, the first lead screw 55 is driven to move. The first lead screw 55 drives the first mounting plate 52 to move. The first mounting plate 52 drives the reciprocating wire tube 53 to move up and down a large range along the shaft 51, driving the nozzle body 62 to move to the next area to perform rinsing operations on the condenser 2. The wastewater generated during rinsing is collected through the drain trough 13 and discharged from the discharge port. S4: After rinsing is completed, the controller 11 controls the motor 56 and water pump 68 to stop working. The elastic force generated by the first spring 66 pushes the nozzle body 62 to move in the opposite direction and retract into the insertion groove 61. The insertion groove 61 is sealed by two elastic semi-circular rubber sheets 67. S5: Controller 11 controls circuit breaker 12 to close, connecting the working power supply of the outdoor unit of the air conditioner.
