Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioner heat exchange, and specifically relates to an air conditioner heat exchange device. BACKGROUND

[0002] The core component of an air conditioner is an evaporator, which is composed of multiple rows of copper pipes and aluminum fins. Its core function is to absorb the heat of indoor hot air through refrigerant, to blow back the cooled air to achieve refrigeration. It is a necessary passage for air flow. After long-term use, dust, lint and other impurities will obviously adhere to the surface. These dust will hinder heat exchange, reduce refrigeration effect and increase power consumption. In addition, it will combine with condensate water to breed bacteria and mold, produce odor, affect human health, and even damage air conditioner components over a long period of time.

[0003] The patent document with publication number CN119594606B discloses an automobile air conditioner evaporator, which comprises a bearing outer frame and an evaporator body. The evaporator body is fixedly connected to the inside of the bearing outer frame. The inside top wall of the bearing outer frame is fixedly connected with two flow dividing boxes. The outside of the flow dividing box is fixedly connected with multiple blocking and shrinking air bags. A micro air pump is fixedly connected to the bearing outer frame. The air outlet of the micro air pump is communicated with a gas conveying hose. The end of the gas conveying hose away from the micro air pump penetrates through the outer wall of the bearing outer frame and is communicated with one of the flow dividing boxes. The multiple blocking and shrinking air bags connected with the two flow dividing boxes are located on the two sides of the evaporator body. A first electric control valve is communicated with the blocking and shrinking air bag. The end of the first electric control valve away from the blocking and shrinking air bag is communicated with the flow dividing box.

[0004] The above-mentioned prior art continuously injects gas into the inside of the flow dividing box through the micro air pump, and divides the gas into the blocking and shrinking air bags through the flow dividing box during the process of continuously injecting gas into the inside of the flow dividing box. When the gas continuously enters the inside of the blocking and shrinking air bag, the blocking and shrinking air bag expands. When multiple blocking and shrinking air bags continuously expand laterally, the bearing outer frame can block the evaporator body, so that the evaporator body is blocked in a separate space, so that the evaporator body is not in contact with the external air in the non-use state, to reduce the dust in the external air adhering to the louver fins of the evaporator body. In addition, multiple cleaning brush rods are integrally formed on the outside of the blocking and shrinking air bag. The initial length of the cleaning brush rod is fitted to the outer wall of the evaporator body. During the lateral expansion of the blocking and shrinking air bag, the outer wall of the evaporator body is cleaned back and forth.

[0005] But the scheme still has the following problems, the prior art by blocking the air bag inflation drive cleaning brush rod movement, and then complete the cleaning work of evaporator, but the design there is a key logical vulnerability. Blocking air bag in the inflation process, need to go through from the shrinkage state to the complete deployment of the transition phase of the evaporator is not completely sealed, in the exposed state. Cleaning brush rod operation of dust, flocculation and other impurities, will directly drift to the surrounding air, on the one hand, may be attached to the surface of other parts of the air conditioner, resulting in secondary pollution; on the other hand, when the cleaning is completed, the blocking air bag deflates open, the dust drifting in the surrounding will again be settled and attached to the evaporator body, resulting in cleaning work in vain, can not thoroughly remove dust, seriously affect the stability of the cleaning effect. SUMMARY

[0006] The application provides an air conditioner heat exchange device, and aims to solve the problem of incomplete sealing of the evaporator cleaning due to the transition stage of the air bag, leading to impurity drifting, re-sticking, incomplete cleaning and unstable effect in the related art.

[0007] The air conditioner heat exchange device provided by the application, comprising a mounting frame, an evaporator and a dust collection box installed in the mounting frame, a closing assembly and a control assembly are arranged on the mounting frame; the closing assembly comprises a support frame slidingly assembled on the mounting frame, a plurality of closing plates in rotational cooperation with the support frame, cleaning brushes fixed to the side surfaces of the closing plates, and a driving member in transmission connection with the closing plates; the control assembly is connected with the support frame and used for adjusting the sliding position of the support frame; when cleaning the evaporator, the driving member drives the plurality of closing plates to rotate to the same plane, and the side surfaces of adjacent closing plates abut against each other, so that the evaporator is in a closed space, and the cleaning brushes rotate to the direction facing the evaporator along with the closing plates; then the control assembly drives the support frame to drive the cleaning brushes to reciprocate and contact the side surface of the evaporator to clean dust, and the dust collection box synchronously collects dust.

[0008] The effect is that the control assembly is arranged to clean the evaporator when the closure plates are closed to reduce the phenomenon that impurities float everywhere. Specifically, when the evaporator is running, the driving member drives the closure plates to rotate, so that the other adjacent closure plate side is separated, and a ventilation channel is formed between the two closure plates for airflow to pass through. When the evaporator needs to be cleaned, the evaporator stops running, the driving member drives the closure plates to rotate until the plurality of closure plates are rotated to the same plane, at which time the two adjacent closure plates abut each other, and the closure plates and the mounting frame form a closed space for sealing the evaporator. Then the control assembly drives the support frame to reciprocally approach the evaporator, and the support frame moves to drive the cleaning brush to move, so that the cleaning brush reciprocally contacts and rubs the side surface of the evaporator, thereby cleaning the evaporator, while the dust collection box synchronously collects dust. By cleaning the impurities on the surface of the evaporator after the closure plates are closed, the phenomenon that impurities float everywhere can be effectively avoided, secondary pollution is reduced, and the cleaning efficiency of the evaporator is improved.

[0009] Preferably, the mounting frame is provided with openings corresponding to the two sides of the evaporator, and the two groups of support frames are respectively slidably assembled in the openings on the two sides of the mounting frame; when the closure plate side surfaces abut each other, the openings on the two sides of the mounting frame are synchronously closed to enable the evaporator to be located in the closed space.

[0010] By arranging the closure plates on both sides of the mounting frame, the airflow channels on both sides of the evaporator can be controlled by the closure plates, and the evaporator can be easily closed.

[0011] Preferably, the driving member includes a push cylinder, a connecting rod one, a connecting rod two, and a rotating rod.

[0012] The push cylinder drives the connecting rod one to move, the connecting rod one drives the jack on the connecting rod two to move through the connecting rod two, the jack cooperates with different positions in the waist-shaped slot when moving, thereby driving the rotating rod to rotate, and the rotating rod can drive the closure plate to rotate when rotating, thereby adjusting the angle of the closure plate to control the opening or closing of the ventilation channel.

[0013] Preferably, the control assembly comprises: a control motor mounted in a mounting frame, an intermediate piece arranged at the output end of the control motor, a control rope located between the two support frames and connected to the support frames at both ends, and an elastic member, wherein the mounting frame is provided with a fixed plate, the control rope passes through the fixed plate, one end of the elastic member is connected to the support frame, and the other end is connected to the fixed plate, the elastic member is used to push the two support frames away from each other, the control motor drives the control rope through the intermediate piece, so that the two ends of the control rope are close to each other and pull the two support frames close to each other, so that the support frames move close to the evaporator.

[0014] The control motor drives the control rope through the intermediate piece, and the control rope is always in a tension state during the process. When the control rope deforms, it pulls the support frame to move and compresses the elastic member at the same time. After the intermediate piece is separated from the control rope, the elastic member drives the support frame to move back to the original position. Thus, the support frame moves back and forth to provide a basis for the cleaning brush to contact the evaporator and clean it.

[0015] Preferably, the fixed plate is provided with an extension plate, and the intermediate piece comprises: a control plate connected to the output shaft of the control motor, a control rod arranged on the control plate, and a push plate slidingly assembled on the extension plate, wherein the sliding direction of the push plate is perpendicular to the control rope, the control rod is arranged at an interval from the rotation axis of the control plate, the control rod abuts against the side of the push plate away from the control rope, and the rotation axis of the control plate is arranged perpendicular to the sliding direction of the push plate.

[0016] The control motor drives the control plate to rotate, and the control plate drives the control rod to rotate around the center of the control plate. When the control rod abuts against the push plate, the push plate can be driven to move. The push plate contacts the control rope when moving, and then pushes the middle position of the control rope. Since the control rope is in a straight line state initially, the distance between the two ends of the control rope will change when the push plate pushes the control rope, thereby pulling the support frame to adjust the position of the support frame.

[0017] Preferably, when two adjacent closing plates are separated, a ventilation channel is formed between them, the ventilation channel is completely opened when the closing plates are rotated to be parallel to each other, and the cleaning brush is arranged perpendicular to the closing plates; when the ventilation channel is opened, the cleaning brush is located in the ventilation channel to intercept the dust passing through the ventilation channel.

[0019] Preferably, the connecting rod two is in sliding cooperation with the connecting rod one, and the connecting rod one is arranged in sliding cooperation with the connecting rod two along the length direction of the connecting rod one.

[0020] When the push plate moves through the control rope to drive the support frame to move, the connecting rod one moves relative to the connecting rod two at the end of the connecting rod two, avoiding the connecting rod one and the connecting rod two from interfering with the movement of the support frame, while not affecting the control of the angle of the closing plate.

[0021] Preferably, the connecting rod two is arranged along the arrangement direction of the plurality of closing plates, and the plurality of jacks are arranged along the length direction of the connecting rod two, and the plurality of jacks are matched with the rotating rods on the plurality of closing plates respectively.

[0024] When the push cylinder is started, the two connecting rod twos can be driven to move through the connecting rod one at the same time, and then the closing plates on both sides of the mounting frame are adjusted at the same time, so that the openings on both sides of the mounting frame are opened or closed synchronously.

[0025] Preferably, the closing plate is provided with a clamping groove on the side close to the adjacent closing plate, and the inner walls of the clamping grooves on the two adjacent closing plates abut against each other when the closing plate is closed.

[0026] By arranging the clamping groove matched with the adjacent closing plate on the side of the closing plate, after the plurality of closing plates are rotated to the same plane, the inner walls of the clamping grooves on the sides of the closing plates abut against the inner walls of the clamping grooves on the sides of the adjacent closing plates, so that the stability of the cooperation between the closing plates is improved, and after abutting, the closing plate can be limited to continue to rotate, so that the closing plate stops rotating when the opening on the mounting frame is completely blocked.

[0027] Beneficial effects:

It can prevent impurities from floating around during cleaning, avoid impurities from re-attaching to other parts of the equipment or spreading to the surrounding environment, and improve the cleaning efficiency of the evaporator.

DETAILED DESCRIPTION

[0040] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0041] As Figures 1 to 9As shown, the air conditioner heat exchange device of the present application comprises an evaporator 2 and a mounting frame 1 arranged outside the evaporator 2, that is, the evaporator 2 is mounted in the mounting frame 1. The mounting frame 1 is provided with a closing assembly 4, a control assembly 5 and a dust suction box 3, and opposite sides of the mounting frame 1 are each provided with an opening 11, the two openings 11 correspond to the two sides of the evaporator 2 respectively, the closing assembly 4 is mounted in the opening 11 of the mounting frame 1 and is used for controlling the closing of the opening 11, after the closing assembly 4 closes the openings 11 on both sides of the mounting frame 1, the evaporator 2 is in a closed space, which avoids the problem that impurities adhere to the surface of the evaporator 2 when the device is stopped, and the control assembly 5 cooperates with the closing assembly 4 to clean the impurities and dust on the surface of the evaporator 2, and the dust suction box 3 is located at the bottom of the mounting frame 1 and synchronously collects dust when the impurities on the surface of the evaporator 2 are cleaned.

[0042] When the evaporator 2 is normally operated, the closing assembly 4 is completely opened, the opening 11 on the mounting frame 1 is not blocked, and the airflow can smoothly pass through the evaporator 2 for heat exchange, which avoids energy loss caused by structural blockage. When the device is stopped, the closing assembly 4 will automatically reset and completely close the openings 11 on both sides of the mounting frame 1. At this time, the evaporator 2 is wrapped in the closed space formed by the mounting frame 1 and the closing assembly 4, which can effectively isolate dust, flocculation, insects and other impurities in the air, thereby avoiding impurities adhering to the fins or pipeline surface of the evaporator 2 from the source, and solving the problems of easy dust accumulation after the traditional evaporator 2 is stopped, affecting the heat exchange efficiency when starting next time and needing frequent manual cleaning.

[0043] Referring to Figure 1 , Figure 5 , Figure 6 , Figure 7 The closing assembly 4 comprises a support frame 41, a closing plate 42, a cleaning brush 43 and a driving member 44, the support frame 41 is assembled on the mounting frame 1, the closing plate 42 is mounted on the support frame 41, a plurality of closing plates 42 are arranged on the support frame 41, the closing plate 42 is rotationally connected with the support frame 41, the rotation axes of the plurality of closing plates 42 are arranged in parallel, the cleaning brush 43 is arranged on the side surface of the closing plate 42, and the output end of the driving member 44 is in transmission connection with the closing plate 42, and the driving member 44 is used for driving the closing plate 42 to rotate.

[0044] The driving member 44 drives the closing plate 42 to rotate, when the plurality of closing plates 42 rotate to the same plane, two adjacent closing plates 42 abut each other to close the opening 11, so that the evaporator 2 is in a closed space.

[0045] When the evaporator 2 is running, the driving member 44 drives the closing plate 42 to rotate, so that two adjacent closing plates 42 are separated, and a ventilation passage is formed between the two adjacent closing plates 42, and the airflow can flow through the surface of the evaporator 2 through the ventilation passage and exchange heat with the refrigerant in the evaporator 2. In addition, the driving member 44 can control the rotation angle of the closing plate 42 according to the real-time running power of the evaporator 2 and the system load demand. When the power of the evaporator 2 increases, the rotation angle of the closing plate 42 increases, the cross-sectional area of the ventilation passage expands, the airflow passing through per unit time increases, and the heat exchange efficiency is ensured to match the load demand; when the power of the evaporator 2 decreases, the rotation angle of the closing plate 42 decreases, the cross-sectional area of the ventilation passage decreases, and the airflow decreases accordingly, which avoids waste of energy and realizes energy-saving operation of the system.

[0046] With reference to Figure 7 , Figure 8 , Figure 9 , the cleaning brush 43 is arranged perpendicularly to the closing plate 42, and the cleaning brush 43 moves synchronously with the plate body during the rotation of the closing plate 42. When the closing plate 42 rotates from the closed state to 90 degrees, all the closing plates 42 are in a horizontal state parallel to each other, and at this time, the cross-sectional area of the ventilation passage between the adjacent closing plates 42 reaches the maximum value, that is, the ventilation passage is in a fully open state. At this time, the cleaning brush 43 is just located in the core area of the ventilation passage, forming a multi-layer three-dimensional filter screen, and when the airflow flows through the passage, the dust, hair and other impurities in the air can be effectively intercepted by the cleaning brush 43, which significantly reduces the contact between the impurities and the surface of the evaporator 2, reduces the dust accumulation risk of the evaporator 2, and prolongs the cleaning cycle and service life of the evaporator 2.

[0047] With reference to Figure 9 In this embodiment, when the closing plate 42 is fully opened, the length of the cleaning brush 43 is half of the width of the ventilation passage, so as to ensure the flow of the airflow. In other embodiments, the length parameter of the cleaning brush 43 can be adjusted, so that when the ventilation passage is fully opened, the free end of the cleaning brush 43 away from the closing plate 42 can slightly contact the side of the adjacent closing plate 42 away from the cleaning brush 43, that is, the cleaning brush 43 spans the width direction of the entire ventilation passage. This design makes the airflow pass through the filter layer formed by the cleaning brush 43 when passing through the passage, which greatly improves the interception efficiency of the small impurities. The flocking density of the cleaning brush 43 cannot be too high, so as to reduce the airflow resistance, improve the ventilation efficiency, and avoid affecting the normal operation of the evaporator 2.

[0048] With reference to Figure 7 , Figure 8 , Figure 9The side of the closing plate 42 is provided with a clamping groove 8 located on the side of the closing plate 42 abutting against the adjacent closing plate 42; when the plurality of closing plates 42 are rotated to the same plane, the inner walls of the clamping grooves 8 on the adjacent two closing plates 42 abut against each other. The contact area between the two closing plates 42 is increased, and the stability of the two closing plates 42 during cooperation is improved.

[0049] Referring to Figures 2 to 7 The driving member 44 comprises a push cylinder 441, a connecting rod one 442, a connecting rod two 443, and a rotating rod 444. The push cylinder 441 is installed in the mounting frame 1. The connecting rod one 442 is arranged at the output end of the push cylinder 441 and is perpendicular to the piston rod of the push cylinder 441. The connecting rod two 443 is slidingly arranged in the support frame 41 along the length direction thereof. The connecting rod one 442 is perpendicular to the connecting rod two 443. The end of the connecting rod one 442 is connected with the connecting rod two 443. The rotating shaft of the closing plate 42 extends into the support frame 41 and is connected with the rotating rod 444. The waist-shaped groove 6 is arranged on the rotating rod 444. The top rod 61 is arranged on the connecting rod two 443. The sliding direction of the connecting rod two 443 is perpendicular to the rotating shaft of the closing plate 42, and the connecting rod two 443 is located on one side of the rotating shaft of the closing plate 42. The top rod 61 is slidingly arranged in the waist-shaped groove 6.

[0050] When the closing plate 42 needs to be rotated, the push cylinder 441 drives the connecting rod one 442 to move, the connecting rod one 442 drives the connecting rod two 443 to move, and the connecting rod two 443 drives the top rod 61 to move, so that the top rod 61 cooperates with different positions in the waist-shaped groove 6, thereby driving the rotating rod 444 to rotate, and the rotating rod 444 drives the closing plate 42 to rotate, thereby adjusting the position of the closing plate 42.

[0051] Referring to Figure 5 , Figure 7 The top rod 61 is provided in plurality. The plurality of top rods 61 are arranged along the length direction of the connecting rod two 443. The plurality of top rods 61 and the plurality of closing plates 42 are arranged one by one. The corresponding rotating rod 444 is also provided with a plurality of corresponding rotating rods 444 corresponding to the plurality of closing plates 42. When the connecting rod two 443 moves, the plurality of top rods 61 are simultaneously driven to move, thereby simultaneously driving the plurality of closing plates 42 to rotate, improving the adjustment efficiency of the closing plate 42, and facilitating the control of the rotation angle of the closing plate 42.

[0052] The support frame 41 is slidingly arranged on the mounting frame 1 and is installed in the opening 11 on the side of the mounting frame 1. The support frame 41 is provided in two groups, and the two groups of support frames 41 are arranged in the openings 11 on the two sides of the mounting frame 1. The support frame 41 slides in the direction towards the evaporator 2. The control assembly 5 is connected with the support frame 41 to adjust the position of the support frame 41.

[0053] When multiple closing plates 42 rotate to the same plane to close the opening 11, the cleaning brush 43 is arranged towards the evaporator 2. Then, the control component 5 drives the support frame 41 to move back and forth close to the evaporator 2. While the support frame 41 moves back and forth, it drives the cleaning brush 43 to reciprocate and contact the side of the evaporator 2. At the same time, the contact end of the cleaning brush 43 with the evaporator 2 can deform to clean the impurities on the surface of the evaporator 2.

[0054] Reference Figure 5 , Figure 7 Link 1 442 is positioned between two link 2 443. The end of link 1 442 is connected to link 2 443, so that when the push cylinder 441 moves link 1 442, it can simultaneously move both link 2 443, thereby simultaneously adjusting the angle of the two sets of closed plates 42.

[0055] Reference Figure 6 Link 2 443 is slidably engaged with link 1 442, with link 1 442 sliding relative to link 2 443 along the length of link 1 442. When the control component 5 moves the support frame 41 on the mounting frame 1, link 2 443 can move relative to link 1 442 to reduce the interference of link 1 442 with the movement of the support frame 41.

[0056] Reference Figure 2 , Figure 3 The control component 5 includes a control motor 51, an intermediate component 52, a control rope 53, and an elastic element 54. A fixing plate 7 is provided inside the mounting frame 1, located between two support frames 41. One end of the control rope 53 is connected to the support frame 41, and the other end passes through the fixing plate 7 and connects to the other support frame 41. The control rope 53 reciprocates within the fixing plate 7. The control motor 51 is installed inside the mounting frame 1, and its output end cooperates with the intermediate component 52. The elastic element 54 is a spring, with one end connected to the fixing plate 7 and the other end connected to the support frame 41. The elastic element 54 is used to push the support frame 41 to move away from the fixing plate 7. Two elastic elements 54 are provided, and each elastic element 54 is sleeved outside the control rope 53. The elastic element 54 is used to move the two support frames 41 away from each other.

[0057] The elastic element 54 is always in a compressed state. Initially, the elastic element 54 drives the two support frames 41 to move away from each other and tensions the control rope 53. When it is necessary to adjust the position of the support frame 41, the control motor 51 pushes the middle part of the control rope 53 through the intermediate part 52, so that the two ends of the control rope 53 move closer to each other and pull the support frame 41 to move. When the intermediate part 52 removes the pushing force on the control rope 53, the support frame 41 is reset under the action of the elastic element 54, thereby realizing the reciprocating movement of the support frame 41.

[0058] ReferenceFigure 2 、 Figure 3 The fixed plate 7 is provided with an extension plate 71, and the intermediate part 52 comprises a control plate 521, a control rod 522 and a push plate 523. The control plate 521 is coaxially connected with the control motor 51. The control rod 522 is arranged on the control plate 521 and located on the side of the control plate 521 away from the control motor 51. The control rod 522 is arranged at a distance from the rotation center of the control plate 521. The push plate 523 is in sliding fit with the extension plate 71 and slides in the direction towards the control rope 53. The push plate 523 is located between the control rod 522 and the control rope 53. The sliding direction of the push plate 523 is perpendicular to the rotation axis of the control plate 521.

[0059] The control motor 51 drives the control plate 521 to rotate, and the control plate 521 drives the control rod 522 and the push plate 523 to abut, so as to drive the push plate 523 to move. The push plate 523 moves to push the control rope 53, so as to adjust the position of the support frame 41. When the control rod 522 rotates to separate from the push plate 523, the elastic member 54 drives the control rope 53 and the push plate 523 to reset, so as to realize the reciprocating movement of the push plate 523. In addition, when the control rod 522 separates from the push plate 523, the elastic member 54 releases the elastic potential energy, which pulls the control rope 53 to retract reversely, drives the push plate 523 to reset to the initial position along the guide rail, and directly acts on the support frame 41 to obtain a reverse driving force, so as to quickly move reversely along the slide rail. During the resetting process of the support frame 41, the support frame 41 moves towards the mounting frame 1 at a relatively fast speed due to the relatively large instantaneous pulling force of the elastic member 54, and collides with the mounting frame 1. The high-frequency vibration generated by the collision is transmitted to the cleaning brush 43 on the support frame 41, so that the dust, lint and other impurities attached to the surface of the cleaning brush 43 are detached from the surface of the cleaning brush 43 under the action of the vibration, thereby avoiding that the impurities block the gap of the cleaning brush 43 to affect the cleaning effect and facilitating the collection of the impurities by the dust collection box 3.

[0060] Referring to Figure 1 、 Figure 2 The dust collection box 3 is connected with a negative pressure system. The negative pressure system is used to continuously provide a negative pressure environment lower than the atmospheric pressure in the dust collection box. When the impurities on the surface of the evaporator 2 are cleaned, the cleaned dust, debris and other impurities are quickly sucked into the dust collection box 3, so as to avoid secondary dust pollution. In the embodiment, the negative pressure system adopts a vacuum pump or a centrifugal fan as a power source for generating negative pressure. The dust collection box 3 is provided with a suction hole 31. When the closure plates 42 abut against each other to block the evaporator 2, the suction hole 31 corresponds to the gap between the evaporator 2 and the closure plates 42, so as to collect the impurities through the suction hole 31.

[0061] The implementation principle of the present application is that when the evaporator 2 is running, the driving member 44 drives the closing plate 42 to rotate, so that the two adjacent closing plates 42 are separated, and a ventilation channel is formed between the two closing plates 42, and the airflow can pass through the ventilation channel to flow through the surface of the evaporator 2 for heat exchange. In this process, the cleaning brush 43 inside the closing plate 42 is located in the ventilation channel, and when the airflow passes through the channel, the impurities such as dust, hair and fibers mixed in the airflow can be effectively intercepted by the cleaning brush 43 and directly attached to the surface of the cleaning brush 43. The direct contact between the impurities and the fins of the evaporator 2 can be reduced from the source, and the accumulation of dust on the fins of the evaporator 2 can be avoided, so that the heat exchange efficiency of the evaporator 2 can be maintained for a long time, and the energy consumption of the equipment can be reduced.

[0062] When the evaporator 2 needs to be cleaned, the evaporator 2 is first stopped running, and the driving member 44 is started again to drive all the closing plates 42 to rotate synchronously to the same vertical plane. At this time, the side edges of the adjacent closing plates 42 will be completely engaged through the clamping groove 8 to form a sealed cleaning space isolated from the external environment, so that the evaporator 2 is completely wrapped in the space. Then the control motor 51 pushes the control rope 53 through the intermediate piece 52, and the control rope 53 pulls the support frame 41 connected with the closing plate 42 to move close to the evaporator 2 until the cleaning brush 43 forms a preset pressure with the surface of the fins of the evaporator 2. When the intermediate piece 52 is separated from the control rope 53, the pre-compressed elastic member 54 releases the elastic force to drive the support frame 41 to reverse and reset, realizing the reciprocating movement of the support frame 41. This reciprocating action makes the cleaning brush 43 rub on the surface of the evaporator 2 at a high frequency, and the accumulated dust attached to the fins is completely stripped. During the cleaning process, the dust collection box 3 connected with the sealed space is continuously working. The dust stripped by the cleaning brush 43 is directly sucked into the dust collection box 3 under the action of negative pressure.

[0063] By setting that when the evaporator 2 is cleaned, the evaporator 2 is always in a sealed space, the stripped dust cannot be scattered to the outside of the equipment or the indoor environment, which can reduce the phenomenon that the cleaned dust is scattered everywhere, reduce the secondary pollution of dust, improve the cleaning efficiency and stability. The reciprocating friction cleaning method of the cleaning brush 43 can cover all the fin areas of the evaporator 2 compared with the conventional cleaning, avoid cleaning dead angles, and will not damage the fin structure, and can maintain stable cleaning effect for a long time.

[0064] Although the embodiments of the present application have been shown and described above, it should be understood that the above embodiments are exemplary and cannot be construed as limiting the present application, and those skilled in the art can make changes, modifications, replacements and variations to the above embodiments within the scope of the present application.
