Description

Technical Field

[0001] The present invention relates to the technical field of air conditioner cleaning, and in particular to a cleaning device for a fan coil unit. Background Art

[0002] Fan coil units are an important terminal component of air-conditioning systems and are commonly used cooling and heating terminal devices. They are mainly composed of small fans, motors and coils. When chilled water or hot water flows through the coils, heat is exchanged with the air outside the tubes, so that the air is cooled, dehumidified or heated to adjust the indoor air parameters. However, dust easily accumulates on the coils during long-term use, which affects the cooling and heating efficiency and the quality of the exhausted air. Therefore, fan coils need to be cleaned regularly.

[0003] However, the existing fan coil cleaning device still has the following defects during use:

[0004] 1. Fan coil units are generally installed at high places in the space as needed, so climbing is required during the cleaning process. However, existing cleaning devices can only be carried out by hand, which is not only laborious but also difficult to operate smoothly, which can easily damage the coil.

[0005] 2. During use, the existing cleaning device only sweeps away the dust on the fan coil unit without collecting and processing the dust in a timely manner, which can easily cause air pollution and harm to operators. Summary of the Invention

[0006] The purpose of the present invention is to solve the problems that the above-mentioned existing handheld cleaning devices are not only laborious to use, but also difficult to operate smoothly, easily causing damage to the coil, and the dust swept down is not collected in time, which easily causes air pollution and harms the operator. The present invention provides a cleaning device for a fan coil unit.

[0007] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0008] A cleaning device for a fan coil unit includes a shell, wherein coils are evenly fixedly installed inside the shell, protective nets are fixedly installed on the upper and lower sides of the coils inside the shell, a limiting component is provided at the front opening of the shell, and a cleaning component is provided on the outside of the limiting component.

[0009] Furthermore, the limiting assembly includes a cylindrical tube, a cylindrical tube is provided on the front side of the shell opening, the outer side of the cylindrical tube is symmetrically slidably connected to the mounting plate, and the periphery of the upper and lower sides of the cylindrical tube is symmetrically provided with sliding grooves, and the sliding grooves of the cylindrical tube are both limitedly slidably connected with extrusion blocks, and a spring is fixedly connected between the mounting plate and the extrusion block. The center of the inside of the cylindrical tube is limitedly rotatably connected with a rotating shaft, and the two ends of the rotating shaft extend to the upper and lower sides of the cylindrical tube, and the upper and lower ends of the rotating shaft are fixedly provided with turning handles, so that the rotating shaft can be driven to rotate from both the upper and lower sides, and the periphery of the upper and lower sides of the rotating shaft is symmetrically provided with threaded grooves.

[0010] Furthermore, the inner side of the extrusion block extends inwardly to the interior of the cylindrical tube, and the extrusion block is threadedly connected to the thread groove on the periphery of the rotating shaft, so that the extrusion block can be driven to move up and down during the rotation of the rotating shaft.

[0011] Furthermore, the threads of the thread grooves on the upper and lower sides of the outer periphery of the rotating shaft are opposite to each other. Therefore, when the rotating shaft rotates, the extrusion blocks on the upper and lower sides are driven to move toward or away from each other.

[0012] Furthermore, notches are provided at adjacent locations on the rear sides of the upper and lower mounting plates, and a horizontal roller is connected to the horizontal end surface of the notch of the mounting plate for limiting rotation, and a vertical roller is connected to the vertical end surface of the notch of the mounting plate for limiting rotation. A magnetic strip is fixedly installed at the center of the vertical end surface of the notch of the mounting plate, and the magnetic attraction between the magnetic strip and the upper and lower sides of the front end of the shell is utilized to make the mounting plate close to the upper and lower ports of the shell.

[0013] Furthermore, the cleaning assembly includes a ring, which is movably sleeved on the outer side of the middle part of the cylindrical tube, and a ring groove is opened inside the ring. The front side limit of the ring is plugged with a vacuum cleaner, and the rear side limit of the ring is rotatably connected to a rotating drum, so that the rotating drum can rotate under the action of friction during the movement.

[0014] Furthermore, the drum adopts a hollow design, and cleaning strips are evenly and fixedly connected to the periphery of the drum. Circular holes are opened in the gaps between the cleaning strips on the periphery of the drum, and the circular holes are connected to the interior of the drum, so that dust swept by the cleaning strips can enter the drum through the circular holes.

[0015] Furthermore, the annular groove inside the circular ring is connected to both the rotary drum and the dust collector, and under the action of the dust collector, the dust entering the rotary drum can be sucked into the dust collector through the annular groove.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The present invention, through the coordinated design of the limit component and the cleaning component, can enable the limit component to carry the cleaning component for assembly on the front side of the fan coil unit, and through the movement of the limit component on the front side of the fan coil unit using the design of the mounting plate, thereby driving the cleaning component to perform translational cleaning at different heights inside the fan coil unit, reducing the pressure of directly holding the cleaning component for cleaning, saving more effort, and at the same time, the movement of the cleaning component is more stable, avoiding damage to the coil unit caused by the cleaning component.

[0018] 2. The present invention, through the design of the cleaning component, utilizes the cooperation of the vacuum cleaner and the drum. While the drum drives the cleaning strip to clean, it can also promptly extract and collect the swept dust, avoiding the pollution of the air caused by flying dust and the harm to the operator.

[0031] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0032] A fan coil cleaning device according to a preferred embodiment of the present invention will be described in detail below. Figures 1-4 As shown, a fan coil cleaning device includes a shell 1, the interior of the shell 1 is evenly fixed with coils 2, the upper and lower sides of the coils 2 inside the shell 1 are fixedly installed with protective nets 3, a limit assembly 4 is provided at the front opening of the shell 1, and a cleaning assembly 5 is provided on the outside of the limit assembly 4.

[0033] like Figure 4-Figure 6 、 Figure 8 As shown, the limiting assembly 4 includes a cylindrical tube 41, and the cylindrical tube 41 is provided on the front side of the opening of the shell 1. The outer side of the cylindrical tube 41 is symmetrically slidably connected to the mounting plate 42, and the outer periphery of the upper and lower sides of the cylindrical tube 41 is symmetrically provided with a slide groove 43. The slide groove 43 of the cylindrical tube 41 is limited and slidably connected with an extrusion block 44, and a spring 45 is fixedly connected between the mounting plate 42 and the extrusion block 44. The center of the cylindrical tube 41 is connected to the limiting rotation with a rotating shaft 46, and both ends of the rotating shaft 46 extend to the upper and lower sides of the cylindrical tube 41, and the upper and lower ends of the rotating shaft 46 are fixedly provided with a turning handle 47, so that the rotating shaft 46 can be driven to rotate from both the upper and lower sides, and the outer periphery of the upper and lower sides of the rotating shaft 46 is symmetrically provided with a threaded groove 48.

[0034] The inner side of the extrusion block 44 extends inwardly to the interior of the cylindrical tube 41, and the extrusion block 44 is threadedly connected to the thread groove 48 on the periphery of the rotating shaft 46, so that the extrusion block 44 can be driven to move up and down during the rotation of the rotating shaft 46. The threads of the thread grooves 48 on the upper and lower sides of the periphery of the rotating shaft 46 are opposite. Therefore, when the rotating shaft 46 rotates, the movement of the extrusion blocks 44 on the upper and lower sides is driven to move toward or away from each other.

[0035] like Figure 7As shown, notches are provided at adjacent locations on the rear sides of the upper and lower mounting plates 42. The horizontal end face of the notch of the mounting plate 42 is rotationally limited and connected to a horizontal roller 421. The vertical end face of the notch of the mounting plate 42 is rotationally limited and connected to a vertical roller 422. A magnetic strip 423 is fixedly installed at the center of the vertical end face of the notch of the mounting plate 42. The magnetic attraction between the magnetic strip 423 and the upper and lower sides of the front end of the shell 1 is utilized to make the mounting plate 42 close to the upper and lower ports of the shell 1.

[0036] like Figure 5 、 Figures 9-11 As shown, the cleaning assembly 5 includes a ring 51, which is movably sleeved on the outer side of the middle of the cylindrical tube 41, and a ring groove 52 is provided inside the ring 51. The front side limit of the ring 51 is plugged with a vacuum cleaner 53, and the rear side limit of the ring 51 is rotatably connected to a rotating drum 54, so that the rotating drum 54 can rotate under the action of friction during the movement.

[0037] The rotating drum 54 adopts a hollow design, and cleaning strips 541 are evenly and fixedly connected to the periphery of the rotating drum 54. Circular holes 542 are opened in the gaps between the cleaning strips 541 on the periphery of the rotating drum 54. The circular holes 542 are connected to the interior of the rotating drum 54, so that the dust swept off by the cleaning strips 541 can enter the rotating drum 54 through the circular holes 542.

[0038] The annular groove 52 inside the circular ring 51 is connected to both the rotating drum 54 and the dust collector 53 , and under the action of the dust collector 53 , the dust entering the rotating drum 54 can be sucked into the dust collector 53 through the annular groove 52 .

[0039] The working principle of the present invention is:

[0040] First remove the air guide cover at the air outlet on the front side of the shell 1, and then place the limit assembly 4 on the front side of the air outlet of the shell 1. According to the thickness of the shell 1, the upper and lower turning handles 47 are used to drive the rotating shaft 46 to rotate. During the rotation of the rotating shaft 46, the upper and lower side thread grooves 48 of the rotating shaft 46 are connected with the threads on the inner side of the extrusion block 44, and the extrusion block 44 is connected with the cylindrical tube 41 through the sliding groove 43 to limit the sliding connection. The extrusion block 44 can be driven to move on the cylindrical tube 41, and the design of the opposite threads of the upper and lower side thread grooves 48 can drive the extrusion block 44 to move toward each other.

[0041] During the process of the extrusion blocks 44 moving toward each other, the spring 45 can drive the mounting plate 42 to move toward each other synchronously, so that the mounting plate 42 elastically clamps the upper and lower ends of the front side of the shell 1, and makes the horizontal roller 421 on the mounting plate 42 squeeze and contact the upper and lower ends of the front side of the shell 1, and then pushes the cylindrical tube 41 backward to drive the mounting plate 42 to move backward, so that the vertical roller 422 contacts the edge of the front side of the shell 1, and uses the magnetic strip 423 to attract the magnetic force of the front side edge of the shell 1 to keep the mounting plate 42 attached to the front side of the shell 1.

[0042] In the process of completing the clamping of the limit assembly 4 and the shell 1, the rotating drum 54 is extended to between the coils 2 inside the shell 1, and the vacuum cleaner 53 is plugged into the front side of the ring 51. During cleaning, the elastic clamping of the mounting plate 42 on the front side of the shell 1 and the contact between the horizontal roller 421 and the vertical roller 422 on the mounting plate 42 and the front side of the shell 1 can drive the cylindrical barrel 41 to move left and right on the front side of the shell 1, thereby causing the cylindrical barrel 41 to drive the cleaning assembly 5 to move left and right.

[0043] During the left and right movement of the cleaning component 5, the rotating drum 54 can move between the coils 2. With the friction between the cleaning strip 541 on the periphery of the rotating drum 54 and the protective net 3 and the coils 2, the rotating drum 54 can rotate during the movement, thereby driving the cleaning strip 541 to clean the protective net 3 and the coils 2. While cleaning, the vacuum cleaner 53 is turned on, and the dust swept off by the cleaning strip 541 can enter the rotating drum 54 through the circular hole 542. Under the action of the vacuum cleaner 53, the dust passes through the annular groove 52 and enters the vacuum cleaner 53 to be collected, thereby preventing dust from flying.

[0044] After completing the cleaning of one layer of protective net 3 and coil 2, the rotating drum 54 is rotated and separated from the protective net 3 and coil 2 by driving the ring 51 to rotate around the cylindrical tube 41. Then, the ring 51 is moved up and down outside the cylindrical tube 41 to align the rotating drum 54 with the gap between the next protective net 3 and coil 2, and rotates again to enter between the protective net 3 and coil 2 for the next round of cleaning.

[0045] After cleaning is completed, the rotating shaft 46 is reversed by turning the handle 47, so that the squeezing block 44 drives the mounting plate 42 to expand upward and downward through the spring 45, and then the limiting component 4 and the cleaning component 5 are removed from the housing 1.

[0046] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
