[0037] See also Figures 1 to 7, the present invention provides a technical solution:

[0038] Embodiment 1:

[0040] The cleaning mechanism 5 includes a transmission rod 53 located at the center of the refrigerant tube 25 with a spiral structure inside the heat exchanger 2, a cleaning piece 56 is provided at the right end of the transmission rod 53, the transmission rod 53 and the cleaning piece 56 are slidably connected, the right end of the transmission rod 53 is connected and fixed to the right end inside the heat exchanger 2 through a bearing, the left end of the transmission rod 53 passes through the middle of the left end of the heat exchanger 2 and is fixed to the output shaft of the drive motor 3, and a water-sealed bearing 32 is fixedly connected between the transmission rod 53 and the left end of the heat exchanger 2;

[0041] Specifically, Figures 2 to 4 The cleaning member 56 includes a cleaning rod 55, one end of which is distributed in an annular structure and is sleeved on the outer surface of the refrigerant pipe 25 distributed in a spiral structure. The outer surface of the annular end of the cleaning rod 55 is fixedly connected with a scraper 52. The scraper 52 is designed with a flat structure and is fitted on the inner wall of the heat exchanger 2. The other end of the cleaning rod 55 is slidably connected to the transmission rod 53 through a sliding assembly 54.

[0042] By adopting the above technical solution, when the machine is working, the driving motor 3 is connected to the external power supply and the control device, the driving motor 3 runs and then drives the transmission rod 53 to rotate through the output shaft, the transmission rod 53 cooperates with the water-sealed bearing 32 fixedly installed between the heat exchanger 2 to rotate inside the heat exchanger 2, and at the same time the transmission rod 53 further drives the cleaning rod 55 at one end to cooperate with the sliding assembly 54 to move, and the cleaning rod 55 is controlled to move spirally along the spirally distributed refrigerant pipe 25 through the guiding connection of the guide groove 541 and the guide block 542. The cleaning rod 55 moves along the refrigerant pipe 25 with a spiral structure, and during the movement of the cleaning rod 55, its annular end cooperates with the cleaning sheet 51 and the scraper 52 to scrape and clean the outer surface of the refrigerant pipe 25 and the inner wall of the heat exchanger 2.

[0043] Specifically, Figure 5 and Figure 8 As shown, the sliding assembly 54 includes a guide groove 541 horizontally opened on the outer surface of the transmission rod 53, and a guide block 542 is arranged inside the guide groove 541. The guide block 542 is slidably connected to the guide groove 541, and the two are T-shaped structures that match each other and cannot be separated.

[0044] By adopting the above technical solution, the cleaning rod 55 is controlled to move in a spiral shape along the spirally distributed refrigerant pipe 25 through the guiding connection between the guide groove 541 and the guide block 542.

[0045] Specifically, Figure 6 As shown, a plurality of cleaning sheets 51 are distributed in a ring shape at both ends of the outer surface of the annular end of the cleaning rod 55. One end of the cleaning sheet 51 is in close contact with the outer surface of the refrigerant pipe 25, and the cleaning sheet 51 is made of a high-toughness elastic metal material. A protrusion 511 is provided at the corner of the contact end of the cleaning sheet 51 and the refrigerant pipe 25, and a protrusion 511 is also provided at the corresponding position of the outer surface of the refrigerant pipe 25.

[0046] By adopting the above technical solution, the protrusions 511 squeeze and collide with each other during the displacement of the cleaning sheet 51, so that the cleaning sheet 51 elastically deforms and strikes the refrigerant pipe 25, so that impurities on the outer surface of the refrigerant pipe 25 can be better peeled off, achieving an excellent cleaning effect.

[0047] Embodiment 2:

[0048] like Figure 2 As shown, a heat dissipation mechanism 4 is provided on the left side of the inner surface of the cabinet 1, and the heat dissipation mechanism 4 is connected to the driving motor 3. The driving motor 3 drives and controls the cleaning mechanism 5 to clean the outer surface of the refrigerant pipe 25 and the inner wall of the heat exchanger 2, while driving the cleaning mechanism 5 to operate to further cool down and dissipate heat for the electrical control module 11 located inside the cabinet 1.

[0049] Specifically, Figure 2 and Figure 7 As shown, the heat dissipation mechanism 4 includes an extrusion plate 42 which is symmetrically distributed on the left end of the inner wall of the cabinet 1, and a folded airbag 43 is glued between the two extrusion plates 42. A slide groove 44 is vertically opened at a position corresponding to the extrusion plate 42 on the inner surface of the cabinet 1, and a slider 45 is slidably connected inside the slide groove 44. The two are matched in a T-shaped structure and cannot be separated.

[0050] By adopting the above technical solution, the extrusion plate 42 is guided to move by means of the sliding connection between the slider 45 and the slide groove 44, so that the displacement direction of the extrusion plate 42 is accurate and smooth.

[0051] Specifically, Figure 7 As shown, an air suction pipe 48 is provided between the two slide grooves 44, one end of the air suction pipe 48 extends to the outside of the cabinet 1, and the other end is connected to the folding airbag 43. A plurality of air holes 46 are provided at equal distances on the right end surface of the folding airbag 43, and a transmission structure is provided through the middle of the extrusion plate 42.

[0052] By adopting the above technical solution, the folded airbag 43 in the middle of the extrusion plate 42 is squeezed or stretched to reset, and during this process, the internal gas of the folded airbag 43 is discharged or discharged through the suction pipe 48 or the air hole 46.

[0053] Specifically, Figure 7 As shown, the transmission structure includes a threaded rod 41 passing through the two extrusion plates 42, the upper end of the threaded rod 41 is rotatably connected to the inner wall of the cabinet 1 through a bearing, and the other end is fixedly connected to a bevel gear 2 47, the outer surface of the output shaft of the drive motor 3 is fixedly connected to a bevel gear 1 31, and the bevel gear 1 31 is meshingly transmission-connected with the bevel gear 2 47.

[0054] By adopting the above technical solution, when the driving motor 3 drives the transmission rod 53 to rotate, the bevel gear 1 31 and the bevel gear 2 47 are meshed and connected to drive the threaded rod 41 to rotate, and the two extrusion plates 42 connected to the threaded rod 41 with a spiral transmission are displaced toward or relative to each other under the action of the threaded rod 41 with a bidirectional thread distribution.

[0055] Specifically, Figure 7 As shown, the threaded rod 41 is set with a bidirectional thread at the top and bottom with the middle part as the midpoint, and is respectively connected with two extrusion plates 42 through a spiral transmission.

[0056] By adopting the above technical solution, the two extrusion plates 42 connected to the threaded rod 41 with a spiral transmission are displaced toward or relative to each other under the action of the threaded rod 41 with a bidirectional thread distribution, thereby squeezing or stretching the folding airbag 43 located in the middle of the extrusion plate 42 to reset. During this process, the internal gas of the folding airbag 43 is discharged or discharged through the suction pipe 48 or the air hole 46.

[0057] Specifically, Figure 7 As shown, one-way air valves are provided inside the air intake pipe 48 and the air hole 46, and the motor is a three-phase asynchronous motor that is controlled by an external control unit to rotate in both directions.

[0058] By adopting the above technical solution, during this process, the internal gas of the folding airbag 43 is discharged or discharged through the suction pipe 48 or the air hole 46. The gas input direction of the one-way valve located in the suction pipe 48 and the air hole 46 is adjusted according to the user's needs, and the heat dissipation method of the folding airbag 43 can be freely changed. For example, in a basement with a lower temperature, the hot and cold alternating method of sucking in and discharging the outside air into the cabinet 1 can be adopted. When used in areas with heavy dust, the internal gas of the cabinet 1 is sucked into the folding airbag 43 and discharged from the cabinet 1, so that the user can take dust protection measures.

[0059] Working principle: During operation, the driving motor 3 is connected to an external power supply and a control device. The driving motor 3 runs and drives the transmission rod 53 to rotate through the output shaft. The transmission rod 53 cooperates with the water-sealed bearing 32 fixedly installed between the heat exchanger 2 to rotate inside the heat exchanger 2. At the same time, the transmission rod 53 further drives the cleaning rod 55 at one end to cooperate with the sliding assembly 54 to move. The cleaning rod 55 is also controlled to move spirally along the spirally distributed refrigerant tube 25 through the guiding connection of the guide groove 541 and the guide block 542. The cleaning rod 55 moves along the refrigerant tube 25 distributed in a spiral structure, and during the movement of the cleaning rod 55, its annular end cooperates with the cleaning sheet 51 and the scraper 52 to scrape and clean the outer surface of the refrigerant tube 25 and the inner wall of the heat exchanger 2. By designing the cleaning sheet 51 in the cleaning mechanism 5 and the cleaning sheet 51 fits the convex point 511 at the end of the refrigerant tube 25 and the convex point 511 on the outer surface of the refrigerant tube 25, the cleaning rod 55 can be moved. 55 is driven by the transmission rod 53 to continuously displace the outer surface of the refrigerant tube 25 to clean the refrigerant tube 25 and the inner wall of the heat exchanger 2. At the same time, the cleaning sheet 51 can well scrape and clean the impurities attached to the outer surface of the refrigerant tube 25. In the process of the displacement of the cleaning sheet 51, the protrusions 511 squeeze and collide with each other, so that the cleaning sheet 51 elastically deforms and knocks the refrigerant tube 25, so that the impurities on the outer surface of the refrigerant tube 25 can be better peeled off, achieving an excellent cleaning effect. The cleaning mechanism 5 can simultaneously clean and descale the outer surface of the refrigerant tube 25 and the inner wall of the heat exchanger 2, avoiding the adhesion of scale nodules to affect the alternating hot and cold conversion between the refrigerant tube 25 and the hot water inside the heat exchanger 2, improving the working efficiency of the heat exchanger 2 while ensuring the normal use of the electrical control module 11 inside the cabinet 1, and extending its service life. The scale and impurities cleaned can be cleaned out by the user by opening the drain valve at one end of the heat exchanger 2.

[0060] By designing the heat dissipation mechanism 4, based on the cleaning mechanism 5, when the driving motor 3 drives the transmission rod 53 to rotate, the bevel gear 1 31 is meshed with the bevel gear 2 47 to drive the threaded rod 41 to rotate, and the two extrusion plates 42 connected to the threaded rod 41 in a spiral transmission are displaced toward or relative to each other under the action of the threaded rod 41 with a bidirectional thread distribution, thereby squeezing or stretching the folding airbag 43 located in the middle of the extrusion plate 42 to reset. In this process, the internal gas of the folding airbag 43 is discharged or discharged through the suction pipe 48 or the air hole 46. The gas input direction of the one-way valve located in the suction pipe 48 and the air hole 46 is adjusted according to the user's use requirements, and the heat dissipation mode of the folding airbag 43 is freely changed. For example, in a basement with a relatively low temperature, the hot and cold alternating mode of sucking and discharging the outside air into the cabinet 1 can be adopted. When used in an area with a large amount of dust, the internal gas of the cabinet 1 is sucked into the folding airbag 43 and discharged from the cabinet 1, so that the user can take dust protection measures.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
