On the contrary, these embodiments are provided so that the present invention can be more thoroughly understood and the scope of the present invention can be completely conveyed to those skilled in the art.

[0083] As Figures 1 to 14As shown in the figure, an embodiment of the present invention provides a variable frequency control system for an air-to-water machine, including: a base 1 and a variable frequency compressor 2 fixed on the base 1. A condenser 3 is fixed on the base 1, and the condenser 3 is located on one side of the variable frequency compressor 2. An evaporator 4 is fixed on the base 1, and the evaporator 4 is adjacent to the condenser 3. A filter 5 is fixed on the outside of the evaporator 4 through a connecting component. A variable frequency fan 7 is arranged on the side of the condenser 3 away from the evaporator 4. A water collecting tray 13 is arranged below the evaporator 4. An electronic expansion valve 10 is connected between the evaporator 4 and the condenser 3. The system further includes:

[0084] A water storage and spraying part, which is arranged at one end of the water collecting tray 13 and extends to a position away from the evaporator 4 at one end of the variable frequency fan 7 to store water and spray the variable frequency fan 7;

[0085] The water storage and spraying part includes a water storage component and a water spraying component. The water storage component is connected to the water collecting tray 13, and the water spraying component is arranged on the water storage component and is communicated with the water storage component;

[0086] A wiping and cleaning part, which is arranged below the variable frequency fan 7 to wipe and clean the variable frequency fan 7;

[0087] The wiping and cleaning part includes a wiping component and a driving and protecting component. The wiping component is arranged below the variable frequency fan 7, and the driving and protecting component is connected to the wiping component and is located outside the variable frequency fan 7;

[0088] A wet cleaning part, which is arranged above the condenser 3, is connected to the wiping and cleaning part and is located inside the water storage and spraying part to clean the evaporator 4 by the water stored by the water storage and spraying part driven by the wiping and cleaning part;

[0089] The wet cleaning part includes a water supply component and an executing component. The water supply component is arranged inside the water storage component and is connected to the driving and protecting component. The executing component is connected to the water supply component and is arranged to move up and down above the evaporator 4.

[0090] Specifically, the output end of the variable frequency compressor 2 is connected to a supply pipe 8. One end of the supply pipe 8 away from the variable frequency compressor 2 is connected to an inlet pipe 9. The inlet pipe 9 is connected to the input end of the condenser 3. The output end of the condenser 3 is connected to an electronic expansion valve 10. One end of the electronic expansion valve 10 away from the output end of the condenser 3 is connected to a connecting pipe 11, and the connecting pipe 11 is connected to the input end of the evaporator 4. The output end of the evaporator 4 is connected to a return pipe 12, and the return pipe 12 is connected to the input end of the variable frequency compressor 2.

[0091] The base 1 can provide a through channel for the fixed components, and can provide stable support for the variable frequency compressor 2, the condenser 3, the evaporator 4, and the filter 5. The evaporator 4 can provide stable support for the water collecting tray 13. The water collecting tray 13 can provide a collection space and a flow channel for water. The drain pipe 14 can provide a discharge channel for the water in the water collecting tray 13.

[0092] In the actual application process of this embodiment: The staff can use the fixing components to firmly install the base 1 at the working location, and start the variable-frequency compressor 2 and the variable-frequency blower 7. The variable-frequency blower 7 will use the rotational power to draw in air after filtering through the filter 5 and suck it into the evaporator 4, and then pass through the evaporator 4 and the condenser 3 and be blown out from the air hood 6, so that the air circulates, and at the same time, the variable-frequency compressor 2 transports the high-temperature and high-pressure gaseous refrigerant to the inside of the inlet pipe 9 through the supply pipe 8, so that the high-temperature and high-pressure gaseous refrigerant enters the condenser 3 through the inlet pipe 9 and circulates. The condenser 3 uses heat exchange to dissipate the heat of the high-temperature and high-pressure gaseous refrigerant to the outside, and then converts the high-temperature and high-pressure gaseous refrigerant into a medium-temperature and high-pressure liquid refrigerant, which is discharged from the output end of the condenser 3 into the electronic expansion valve 10. The electronic expansion valve 10 can control the flow rate of the refrigerant according to the actual needs, so that the medium-temperature and high-pressure liquid refrigerant passes through the electronic expansion valve 10 and enters the connecting pipe 11. In this process, the medium-temperature and high-pressure liquid refrigerant is throttled and depressurized, so that the refrigerant has a suitable pressure after passing through the electronic expansion valve 10. Subsequently, the medium-temperature and low-pressure liquid refrigerant enters the inside of the evaporator 4 through the connecting pipe 11. The evaporator 4 uses the suddenly enlarged channel inside to reduce the pressure of the medium-temperature and low-pressure liquid refrigerant, and the refrigerant quickly evaporates and vaporizes, absorbing a large amount of heat. As a result, the surface temperature of the evaporator 4 drops sharply, resulting in a large difference between the temperature of the evaporator 4 and the surrounding ambient temperature. This promotes the condensation of moisture in the circulating air on the surface of the evaporator 4, and the condensed moisture will fall into the water collection tray 13 under the action of gravity for collection, thus realizing the function of making water from air.

[0093] The variable-frequency blower 7 and the variable-frequency compressor 2 can control the working efficiency according to the actual needs, so as to conveniently adjust the water production rate and improve flexibility.

[0094] As a preferred embodiment of the present invention, the water storage member includes:

[0095] A drain pipe 14 is provided through one end of the water collection tray 13 away from the evaporator 4 and penetrates through the base 1;

[0096] A water storage cylinder 18 is fixed at one end of the water collection tray 13 away from the evaporator 4 and is located on one side of the drain pipe 14;

[0097] A water passing port 59 is opened through one end of the water collection tray 13 away from the evaporator 4 and is communicated with the water storage cylinder 18.

[0098] Specifically, one end of the drain pipe 14 away from the water collecting tray 13 is connected with a three-way solenoid valve 15. One end of the three-way solenoid valve 15 is equipped with a flange pipe 16, and the other end of the three-way solenoid valve 15 is equipped with a flange plate 17. The water collecting tray 13 can provide stable support for the water storage cylinder 18. The water storage cylinder 18 can provide a storage space for water, and the water collecting tray 13 can provide a space for opening the water passing port 59. The water passing port 59 can provide a channel for water to enter or discharge from the water storage cylinder 18.

[0099] The spraying member includes:

[0100] A water pump 19, fixed on the water storage cylinder 18;

[0101] A suction pipe 20, one end of which is connected to the input end of the water pump 19, and the other end of which penetrates through the side of the water storage cylinder 18 away from the water collecting tray 13;

[0102] A spray pipe 21, one end of which is fixed to the output end of the water pump 19, and the other end of which extends to a position of the variable frequency blower 7 away from the evaporator 4, and the other end is bent towards the direction close to the variable frequency blower 7.

[0103] Specifically, the water pump 19 can provide stable support for the suction pipe 20 and the spray pipe 21. The spray pipe 21 can be deformed under the action of an external force and will maintain its current position and shape after the external force disappears, and can provide a flow channel for water.

[0104] In the actual application process of this embodiment, when a certain amount of water is collected in the water collecting tray 13, as the collected water increases, part of the water will flow through the water passing port 59 and into the inner side of the water storage cylinder 18 for storage, and the other part of the water will enter the inner side of the drain pipe 14 and flow along the drain pipe 14 into the three-way solenoid valve 15. The staff can use the fixing component to connect the water delivery pipeline with the flange plate 17, so that the prepared water can pass through the drain pipe 14 and the three-way solenoid valve 15 and enter the pipeline connected to the flange plate 17.

[0105] The staff can control the operation of the water pump 19 supported by the water storage cylinder 18 according to the actual needs, so that the water pump 19 sucks out the water stored in the water storage cylinder 18 through the suction pipe 20 and conveys it into the spray pipe 21. Subsequently, the water will flow along the spray pipe 21 under the drive of the water pump 19 and be sprayed onto the variable frequency blower 7, thereby flushing the variable frequency blower 7.

[0106] In another preferred embodiment of the present invention, the wiping member includes:

[0107] A guide sleeve 22, arranged below the variable frequency blower 7;

[0108] A brush plate 24, arranged to be lifted and lowered inside the guide sleeve 22, and the end close to the variable frequency blower 7 is an inclined surface;

[0109] The cotton brush 25 is fixed on one side of the brush plate 24 close to the evaporator 4;

[0110] The connecting rod 26 is fixed at one end of the brush plate 24 away from the variable-frequency blower 7 and is arranged through one side of the guide sleeve 22 away from the evaporator 4.

[0111] Specifically, the wind hood 6 can provide stable support for the guide sleeve 22. The guide sleeve 22 can provide a lifting space and a guiding and limiting function for the brush plate 24 and the connecting rod 26. The brush plate 24 can stably support the cotton brush 25. The cotton brush 25 can be deformed under the action of an external force and will rebound after the external force disappears, and it has adsorption property. The brush plate 24 can provide support for the connecting rod 26.

[0112] The driving and protecting part includes:

[0113] The wind hood 6 is arranged outside the variable-frequency blower 7, is fixedly connected with the evaporator 4, and is fixedly connected with the guide sleeve 22;

[0114] The through port 23 is arranged through the wind hood 6 and is located outside the inclined surface of the brush plate 24;

[0115] The guide groove 44 is opened on the inner side of the wind hood 6 and is adjacent to the through port 23;

[0116] The second reed 45 is arranged on the inner side of the guide groove 44, and one end of it is fixedly connected with the wind hood 6;

[0117] The sliding cover 46 is arranged on the outside of the wind hood 6, is located above the through port 23, and extends to the inside of the guide groove 44 to be connected with the other end of the second reed 45;

[0118] The driving part is arranged below the wind hood 6 and is connected with the connecting rod 26.

[0119] Specifically, the condenser 3 can provide stable support for the wind hood 6. The wind hood 6 can provide a protection function for the variable-frequency blower 7 and can provide a through channel for the air. The through port 23 can provide a through channel for the brush plate 24 and the cotton brush 25. The guide groove 44 can provide a moving space for the sliding cover 46 and can provide a deformation and moving space for the second reed 45. The sliding cover 46 can cover the through port 23 to prevent air from entering the through port 23 to generate turbulence, and the through port 23 can provide a discharge channel for sewage. The second reed 45 can be deformed under the action of an external force and will rebound after the external force disappears.

[0120] The driving part includes:

[0121] The toothed plate 27 is fixed at one end of the connecting rod 26 away from the brush plate 24;

[0122] The servo motor 29 is fixed on one side of the wind hood 6 close to the connecting rod 26;

[0123] The rack 28, having a plurality of them, is uniformly fixed on one side of the toothed plate 27 close to the servo motor 29;

[0124] The gear 31 is arranged at the driving end of the servo motor 29 and meshes with the rack 28.

[0125] Specifically, Akasaka can stably support the rack 28 under the support of the connecting rod 26. The rack 28 is of a concave structure and can mesh with the gear 31. The servo motor 29 can provide support for the screw rod 30 under the support of the wind cover 6 and can drive the screw rod 30 to rotate, and the screw rod 30 can drive the gear 31 to rotate.

[0126] In the actual application process of this embodiment, the staff can control the operation of the servo motor 29 under the support of the wind cover 6 according to the actual needs, so that the servo motor 29 uses the driving end to drive the screw rod 30 to rotate clockwise, so that the screw rod 30 drives the gear 31 to rotate clockwise together. The gear 31 will use the meshing effect to push the rack 28 during the rotation process, so that the rack 28 pushes the toothed plate 27 to move upward. At the same time, the toothed plate 27 will drive the brush plate 24 and the cotton brush 25 to move upward together under the guiding and limiting of the guide sleeve 22 through the connecting rod 26, so that the brush plate 24 and the cotton brush 25 move upward through the through port 23 together. At the same time, the brush plate 24 will use external force and the inclined surface to push the sliding cover 46 during the upward movement, so that the sliding cover 46 moves along the wind cover 6 to one side under the action of the external force and the inclination angle of the inclined surface. At the same time, the sliding cover 46 will squeeze the second reed 45 to contract and deform inside the guide groove 44 during the movement, so that the brush plate 24 and the cotton brush 25 can move upward to the inside of the wind cover 6. As the gear 31 continues to rotate clockwise, the cotton brush 25 can contact the variable-frequency blower 7 under the support of the brush plate 24. At the same time, the staff needs to slow down the rotation speed of the variable-frequency blower 7, so that the variable-frequency blower 7 can be removed from the adhered dust and impurities by the cotton brush 25 and water during the rotation process, preventing the influence on the air circulation rate, improving the air circulation effect and the water production efficiency. The sewage will flow to the inside of the through port 23 under the action of gravity and be discharged to the outside through the through port 23.

[0127] The staff can control the servo motor 29 to drive the screw rod 30 to rotate counterclockwise according to the actual needs, so that the screw rod 30 drives the gear 31 to rotate counterclockwise together. Then the gear 31 uses the meshing effect with the rack 28 to push the toothed plate 27 to move downward, and then the brush plate 24 and the cotton brush 25 move downward together, so that the tops of the cotton brush 25 and the brush plate 24 move to the inside of the through port 23, and then the pushing of the sliding cover 46 is released. Thus, the second reed 45 uses the rebounding force to push the sliding cover 46, so that the sliding cover 46 moves along the guide groove 44 and covers the through port 23.

[0128] As a preferred embodiment of the present invention, the water supply member includes:

[0129] The screw rod 30 is fixed to the driving end of the servo motor 29, passes through the gear 31, and is fixedly connected to the gear 31;

The rubber pad 33 is made of rubber.

[0137] The water pulling part includes:

[0138] The winding ring 38 is rotatably sleeved inside the groove 32;

[0139] The winding rope 39 has one end fixed to the outside of the winding ring 38;

[0140] The conduit 40 is arranged through the side of the water storage cylinder 18 away from the drain pipe 14; the other end of the winding rope 39 passes through the conduit 40 and extends into the water storage cylinder 18;

[0141] There are two pulling ropes 41, and one end of each is symmetrically arranged at the other end of the winding rope 39;

[0142] The rubber plate 42 is arranged inside the water storage cylinder 18, is fixedly connected to the other end of the pulling rope 41, and is located at a position close to the water passing port 59;

[0143] One end of the first reed piece 43 is fixed to the inner wall of the water storage cylinder 18, and the other end is fixedly connected to the rubber plate 42.

[0144] Specifically, a sealing ring 60 is fixed inside the catheter 40, and the sealing ring 60 is located on the outer side of the winding rope 39 in a fitting manner. The groove 32 can provide a rotating space for the winding ring 38, and the gear 31 can cooperate with the groove 32 to provide limit support for the winding ring 38. The winding ring 38 can provide support for the winding rope 39, the catheter 40 can provide a blocking and guiding effect for the winding rope 39, the winding rope 39 can provide support for the pulling rope 41, the water storage cylinder 18 can provide support for the rubber plate 42, and the rubber plate 42 can be attached to the inner side of the water storage cylinder 18 to play a sealing role and can move along the water storage cylinder 18 under the action of an external force. The first reed 43 can be deformed under the action of an external force and will rebound after the external force disappears. The sealing ring 60 has elasticity and can be attached to the winding rope 39 or the pulling rope 41 by using the elasticity, so as to play a sealing role at the catheter 40 to prevent water from being discharged from the catheter 40 to the outside. Moreover, the sealing ring 60 can be deformed under the action of an external force, so as to provide a through channel for the pulling rope 41 and the winding rope 39, and at the same time play a sealing role by using the elasticity.

[0145] In the actual application process of this embodiment, the staff can, according to the actual needs, push the nut 37 to rotate under the support of the screw rod 30, so that the nut 37 uses the rotational power to cooperate with the thread of the screw rod 30, and uses the thread action to push the nut 37 to translate along the screw rod 30 in the direction close to the gear 31, so that the nut 37 can push the pressure plate 34 to move along the screw rod 30 in the direction close to the gear 31 under the guiding action of the pressure rod 35 and the through hole 58 during the movement process, and then the pressure plate 34 pushes the pressure head 36 to move in the inner side of the groove 32 in the direction close to the winding ring 38 through the pressure rod 35, and then the pressure head 36 contacts the winding ring 38 and pushes the winding ring 38 to squeeze the rubber pad 33, so that the rubber pad 33 cooperates with the pressure head 36 to connect the winding ring 38 and the gear 31. When the gear 31 rotates clockwise, it can drive the winding ring 38, the pressure rod 35 and the pressure plate 34 to rotate clockwise together through the pressure head 36 and the rubber pad 33. Then the winding ring 38 can use the rotational power to pull the winding rope 39, so that the winding rope 39 is wound on the inner side of the groove 32 and outside the winding ring 38. During the winding process of the winding rope 39, the winding rope 39 will move along the conduit 40 in the direction close to the winding ring 38 under the action of an external force, so that the winding rope 39 pulls the pull rope 41 in the direction close to the conduit 40 under the guiding and resisting action of the conduit 40, so that the pull rope 41 is pulled into the inner side of the conduit 40 under the action of an external force, and at the same time penetrates the conduit 40 together with the winding rope 39 in the direction close to the winding ring 38 and is wound outside the winding ring 38. At the same time, the pull rope 41 will use the pulling force to pull the rubber plate 42 to move along the inner wall of the water storage cylinder 18 in the direction close to the conduit 40 during the movement process, and at the same time the rubber plate 42 will squeeze and deform the first reed 43 during the movement process, so that the rubber plate 42 can push the water stored in the water storage cylinder 18 to move in the direction close to the conduit 40 during the movement process. Under the guiding of the water storage cylinder 18 and the sealing action of the cooperation of the conduit 40, the sealing ring 60, the winding rope 39 and the pull rope 41, the water cup rubber plate 42 pushes and squeezes the water to flow into the inner side of the hose 48 and flows along the hose 48 into the inner side of the water distribution cylinder 55, so that the water distribution cylinder 55 stores water and distributes the water to the water pipe 54. Then the water will flow through the water pipe 54 into the inner side of the nozzle 53 and be sprayed out from the output end of the nozzle 53 onto the outer surfaces of the evaporator 4 and the brush 57.

[0146] As a preferred embodiment of the present invention, the actuator includes:

[0147] A multi-stage electric rod 50, fixed on one side of the condenser 3 through a connecting component;

[0148] A baffle 51, fixed at the telescopic end of the multi-stage electric rod 50 and extending above the condenser 3;

[0149] An N plate 52, fixed on the outer side of the baffle 51;

[0150] The guard plate 56 is fixed at both ends of the N plate 52 and is located between the evaporator 4 and the condenser 3, and between the evaporator 4 and the filter 5;

[0151] There are multiple brush hairs 57, which are evenly fixed on the side of the guard plate 56 close to the evaporator 4 and match the gap of the evaporator 4.

[0152] Specifically, a switch 47 is arranged between the guide sleeve 22 and the connecting rod 26. The fixed end of the switch 47 is fixedly connected to the guide sleeve 22, and the switch 47 is triggered by being squeezed by the connecting rod 26. When the switch 47 is triggered, it will control the multi-stage electric rod 50 to extend. After the squeezing force of the switch 47 disappears, it will bounce back. The switch 47 in the bounced state will control the multi-stage electric rod 50 to contract. The multi-stage electric rod 50 can provide a stable support for the baffle 51 under the support of the condenser 3. The baffle 51 can provide support for the hose 48 and can stably support the N plate 52. The N plate 52 can provide a stable support for the guard plate 56. The guard plate 56 can stably support the brush hairs 57. The brush hairs 57 can deform under the action of an external force and have a resilience.

[0153] The water supply member includes: a hose 48, one end of which is arranged through one side of the water storage cylinder 18 close to the variable frequency blower 7, and the other end is located above the baffle 51;

[0154] A positioning ring 49 is fixed on the outer side of the air hood 6 and is sleeved on the outer side of the hose 48;

[0155] There are multiple spray heads 53, which are fixedly connected through the N plate 52 and are located inside the N plate 52;

[0156] A water pipe 54 is fixed on the outer side of the spray head 53 and penetrates through one side of the N plate 52 close to the baffle 51;

[0157] A water distribution cylinder 55 is fixed at the end of the water pipe 54 far from the spray head 53 and is connected to the other end of the hose 48.

[0158] Specifically, the positioning ring 49 can provide a positioning function for the hose 48 under the support of the air hood 6 to prevent the hose 48 from being displaced randomly. The water distribution cylinder 55 can provide a water storage space and can distribute water to each water pipe 54. The water pipe 54 can provide support for the spray head 53, and the N plate 52 can stably support the spray head 53. The spray head 53 can provide a spraying channel for the water.

[0159] In the actual application process of this embodiment, when the gear 31 rotates clockwise and drives the connecting rod 26 to move upward through the rack 28 and the toothed plate 27, the connecting rod 26 will gradually separate from the switch 47, causing the switch 47 triggered by extrusion to bounce up, thereby controlling the contraction of the multi-stage electric rod 50. The multi-stage electric rod 50 uses the telescopic end to push the baffle 51 downward under the support of the condenser 3, so that the baffle 51 drives the spray head 53, the water pipe 54, the water distribution cylinder 55 and the guard plate 56 to move downward together through the N plate 52, and the guard plate 56 is inserted into the gap between the condenser 3 and the evaporator 4 and the gap between the evaporator 4 and the filter plate. At the same time, the guard plate 56 will drive the brush 57 to move together, so that the brush 57 contacts the outer surface of the evaporator 4 during the movement, and uses the water sprayed by the spray head 53 to clean the outer surface of the evaporator 4, preventing the dirt on the outer wall of the evaporator 4 from affecting the water production effect.

[0160] Before the rubber plate 42 moves towards the direction close to the conduit 40, the staff needs to control the three-way solenoid valve 15 to operate, so that the three-way solenoid valve 15 adjusts the water inside the drain pipe 14 to flow out through the three-way solenoid valve 15 itself into the inside of the flange pipe 16, while blocking the water from entering the pipeline connected to the flange 17. As a result, the water sprayed by the spray head 53 can drip into the inside of the water collecting tray 13, flow out along the water collecting tray 13 into the inside of the drain pipe 14, flow into the three-way solenoid valve 15 along the drain pipe 14, finally pass through the three-way solenoid valve 15 and flow into the inside of the flange pipe 16, and then be discharged to the outside through the flange pipe 16.

[0161] After the rubber plate 42 moves towards the direction close to the conduit 40 to the limit, the winding rope 39 and the pulling rope 41 will be blocked by the water storage cylinder 18 under the support of the rubber plate 42, resulting in that the winding rope 39 and the pulling rope 41 can no longer be pulled. At this time, the gear 31 will use the rotational power to overcome the friction between the rubber pad 33 and the winding ring 38, so that the gear 31 drives the rubber pad 33 to rotate together, and uses part of the friction force to continuously push the winding ring 38, causing the winding ring 38 to remain stationary against the restoring force of the first reed 43. The staff can rotate the nut 37 according to the actual needs, so that the nut 37 moves away from the gear 31 by means of the thread action with the screw rod 30, thereby releasing the extrusion effect of the pressure plate 34, the pressure rod 35 and the pressure head 36 on the winding ring 38, so that the winding ring 38 can rotate around the gear 31 in the inner side of the groove 32. Subsequently, the deformed first reed 43 will use the restoring force to push the rubber plate 42 to move and reset along the water storage cylinder 18 away from the conduit 40 under the support of the water storage cylinder 18. At the same time, the winding rope 39 and the pulling rope 41 will drive the winding ring 38 to rotate counterclockwise under the support of the gear 31 under the drive of the rubber plate 42, and release the wound pulling rope 41 and winding rope 39 during the rotation. During the process of the rubber plate 42 moving away from the conduit 40, the water entering the water storage cylinder 18 will be pushed by an external force to pass through the water passing port 59 into the inside of the water collecting tray 13.

[0162] Working principle: The variable-frequency fan 7 sucks in air by rotating. The air enters the evaporator 4 after being filtered by the filter 5. The surface temperature of the evaporator 4 decreases, and the moisture in the air condenses into water droplets. The water droplets fall into the water collection tray 13, and the temperature difference between the condenser 3 and the evaporator 4 promotes the condensation of the moisture in the air.

[0163] The collected water is guided into the water storage component and sprayed onto the variable-frequency fan 7 through the water pump 19, the suction pipe 20, and the spray pipe 21 for cleaning the fan. After the fan is cleaned, the water flows back into the water collection tray 13 and is stored by the water storage component again to ensure the recycling of water resources.

[0164] The wiping and wet cleaning parts work together to clean the evaporator 4 and the variable-frequency fan 7. The wiping part and the driving and protecting part cooperate to be able to timely remove the dust on the surface of the fan and ensure the operation efficiency of the equipment. The wet cleaning part cleans the surface of the evaporator 4 by spraying water to ensure the normal operation of the evaporator 4 and avoid the influence of water freezing or fouling on the water production effect.

[0165] By adjusting the variable-frequency compressor 2 and the variable-frequency fan 7, the working efficiency can be automatically adjusted according to the changes in air humidity and temperature, achieving an energy-saving effect and at the same time optimizing the efficiency of air water production.

[0166] Realize automatic adjustment and intelligent cleaning, maintain the long-term stable operation of the equipment, reduce manual intervention, and improve the self-maintenance ability of the equipment.

[0167] The water storage component improves the utilization rate of water. The design of the wet cleaning part and the wiping part enables the equipment to regularly clean the evaporator 4 and the variable-frequency fan 7, ensuring the long-term effective operation of the equipment, avoiding the performance decline caused by dirt accumulation, with a reasonable design structure, easy installation and maintenance of each component, a simple and effective overall system design, and improved convenience and safety in the use of the equipment.

[0168] The above is the preferred implementation mode of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle described in the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
