Detailed implementation manners

[0032] It should be noted that, without conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0033] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0034] In the present invention, unless otherwise stated, the orientation terms such as "upper, lower" are usually in the direction shown in the drawings, or in the vertical, perpendicular or gravitational direction; similarly, for the convenience of understanding and description, "left, right" are usually in the left and right shown in the drawings; "inside, outside" refer to the inside and outside relative to the contour of each component itself, but the above orientation terms do not limit the present invention.

[0035] In order to solve the problem that the cleaning of the air conditioner indoor unit in the prior art is not in place and affects the user experience, the present application provides a cleaning device and an air conditioner indoor unit having the same.

[0036] As shown Figures 1 to 10 in the figure, the cleaning device cleans the blower fan 10 and the volute 20 of the air conditioner indoor unit. The cleaning device includes a machine base 40, a cleaning component, and a driving component 50. Among them, the machine base 40 includes a first mating portion 41, and the first mating portion 41 is surrounded by four sub-mating portions. The cleaning device is installed in the air conditioner indoor unit through the machine base 40. The cleaning component is arranged on the machine base 40. The cleaning component includes a cleaning portion 30 and a second mating portion 60 connected to the cleaning portion 30. The cleaning portion 30 is used to spray liquid onto the blower fan 10 and the volute 20. The driving component 50 is connected to the cleaning component to drive the cleaning component to move, so that the second mating portion 60 cooperates with the first mating portion 41 and slides along each sub-mating portion in sequence, thereby realizing the movement of the cleaning portion 30.

[0037] Applying the technical solution of this embodiment, the cleaning device cleans the blower fan 10 and the volute 20 of the air conditioner indoor unit. The machine base 40 includes a first mating portion 41, and the first mating portion 41 is surrounded by four sub-mating portions. In this way, when it is necessary for the cleaning portion of the cleaning component to spray liquid onto the blower fan 10 and the volute 20, the driving component 50 is started, so that the driving component 50 drives the cleaning component to move. The second mating portion 60 of the cleaning component cooperates with the first mating portion 41 of the machine base 40 and slides along each sub-mating portion in sequence, so that the cleaning portion 30 moves within a preset trajectory, thereby enabling the cleaning portion 30 to clean the blower fan 10 and the volute 20 sufficiently, solving the problem in the prior art that the cleaning of the air conditioner indoor unit is not in place and affecting the user experience, improving the cleanliness of the blower fan 10 and the volute 20, and improving the user experience.

[0038] In other embodiments not shown in the drawings, the cleaning portion is used to spray gas onto the blower fan and the volute. In this way, when it is necessary for the cleaning portion of the cleaning component to spray gas onto the blower fan and the volute, the driving component is started, so that the driving component drives the cleaning component to move. The second mating portion of the cleaning component cooperates with the first mating portion of the machine base and slides along each sub-mating portion in sequence, so that the cleaning portion moves within a preset trajectory, thereby enabling the cleaning portion to clean the blower fan and the volute sufficiently, solving the problem in the prior art that the cleaning of the air conditioner indoor unit is not in place and affecting the user experience, improving the cleanliness of the blower fan and the volute, and improving the user experience.

[0039] It should be noted that the structure of the first mating portion 41 is not limited to this, and the movement trajectory of the cleaning portion can be adjusted according to actual use. Optionally, the first mating portion 41 is surrounded by two, or three, or five, or six sub-mating portions.

[0040] In this embodiment, the cleaning unit 30 can be adjusted in position along the height direction of the cleaning device and can also rotate relative to the machine base 40, thereby expanding the cleaning range of the cleaning unit 30 to achieve a full cleaning of the impeller 10 and the volute 20 by the cleaning unit 30.

[0041] As Figure 3 shown, the four-section mating part includes a first-section mating part 411, a second-section mating part 412, a third-section mating part 413, and a fourth-section mating part 414 that are connected in sequence from head to tail. The first-section mating part 411, the second-section mating part 412, the third-section mating part 413, and the fourth-section mating part 414 are all grooves, and the second mating part 60 is a convex column. The convex column extends into the groove and slides along the extension direction of the groove. In this way, the above setting makes the mating between the second mating part 60 and the first mating part 41 easier and simpler, and also makes the sliding of the second mating part 60 along the first mating part 41 smoother, improving the use reliability of the cleaning device.

[0042] Specifically, the extension direction of the first-section mating part 411 is arranged parallel to the extension direction of the third-section mating part 413, and the extension direction of the second-section mating part 412 is arranged parallel to the extension direction of the fourth-section mating part 414. In this embodiment, the first-section mating part 411, the second-section mating part 412, the third-section mating part 413, and the fourth-section mating part 414 surround to form a rectangle, so that the spraying trajectory of the cleaning unit 30 is a rectangle, thereby achieving a full cleaning of the impeller 10 and the volute 20 by the cleaning unit 30.

[0043] In this embodiment, the extension direction of the first-section mating part 411 is arranged perpendicular to the extension direction of the second-section mating part 412. The extension direction of the first-section mating part 411 is arranged parallel to the first plane, and the extension direction of the second-section mating part 412 is arranged parallel to the second plane.

[0044] It should be noted that the positional relationship between the extension direction of the first-section mating part 411 and the extension direction of the second-section mating part 412 is not limited to this. Optionally, the extension direction of the first-section mating part 411 and the extension direction of the second-section mating part 412 are arranged at an acute angle or an obtuse angle so that the four-section mating part surrounds to form a parallelogram.

[0045] As Figure 2 、 Figures 6 to 8As shown, the cleaning section 30 includes an inlet and a plurality of hole-shaped structures 31 communicating with the inlet, so that liquid or gas enters the cleaning section 30 through the inlet and is ejected through the plurality of hole-shaped structures 31. In this way, the inlet is communicated with the liquid supply device, the liquid supply device supplies liquid to the inlet, the liquid in the liquid supply device enters the cleaning section 30 through the inlet, and finally is ejected onto the impeller 10 and the volute 20 through the plurality of hole-shaped structures 31, thereby increasing the pressure of the liquid ejected from the hole-shaped structures 31 and increasing the impact force of the cleaning section 30 on the impeller 10 and the volute 20.

[0046] Specifically, during the sliding of the second mating part 60 along the first mating part, the movement trajectories of the plurality of hole-shaped structures 31 are rectangles. When the convex column slides along the first section of the mating part 411, the cleaning section 30 slides in the first plane. When the convex column slides along the second section of the mating part 412, the cleaning section 30 slides in the second plane, thereby realizing the movement of the cleaning section 30 relative to the machine base 40 to fully clean the impeller 10 and the volute 20.

[0047] In this embodiment, the cleaning section 30 is a columnar structure, and the columnar structure further includes a communication hole. One end of the communication hole is communicated with the inlet, and the other end of the communication hole is communicated with the hole-shaped structure 31. Among them, the communication hole extends along the axial direction of the columnar structure, and the hole-shaped structure 31 extends along the radial direction of the columnar structure. In this way, the above setting makes the hole-shaped structure 31 an elongated hole, thereby increasing the pressure of the liquid ejected from the hole-shaped structure 31, increasing the impact force of the cleaning section 30 on the impeller 10 and the volute 20, and improving the cleaning effect of the cleaning device.

[0048] Such as Figure 5 、 Figure 6 、 Figure 8 and Figure 9As shown in the figure, the driving assembly 50 includes a driving part 51. The cleaning assembly further includes a cylindrical body 71, a mounting plate body 72, and a mating convex column 73. Among them, the second mating part 60 is arranged on the outer surface of the cylindrical body 71. The mounting plate body 72 is arranged at one end of the cylindrical body 71, and the cleaning part 30 is arranged on the side of the mounting plate body 72 away from the cylindrical body 71. The mating convex column 73 is arranged on the inner surface of the cylindrical body 71. After the driving part 51 extends into the cylindrical body 71 from the other end of the cylindrical body 71, it is snap-connected with the mating convex column 73 to drive the mating convex column 73 to move. The mating convex column 73 drives the second mating part 60 to slide along each section of the sub-mating part in sequence through the cylindrical body 71. In this way, the driving part 51 drives the mating convex column 73 to move, so as to drive the cylindrical body 71 and the cleaning part 30 to move through the mating convex column 73. During the movement of the cylindrical body 71, the second mating part 60 arranged on the cylindrical body 71 extends into the first mating part 41 and slides along the first mating part 41 to define the movement track of the cylindrical body 71, so that the cleaning part 30 moves within a preset range. At the same time, the structure of the above structure is simple, easy to process and implement, and reduces the processing cost of the cleaning device.

[0049] Specifically, after the driving part 51 extends into the cylindrical body 71 from the other end of the cylindrical body 71, it is snap-connected with the mating convex column 73 to drive the mating convex column 73 to move, so as to drive the cylindrical body 71 and the cleaning part 30 to move through the mating convex column 73. During the movement of the cylindrical body 71, the second mating part 60 extends into the first mating part 41 and slides along the first mating part 41, so that the second mating part 60 moves within a preset movement track, thereby restricting the movement of the cleaning part 30 and ensuring that the cleaning part 30 moves within a preset range, thereby improving the use reliability of the cleaning part 30.

[0050] As Figure 9 shown in the figure, the driving part 51 includes a first snap structure 511 and a second snap structure 512. Among them, the second snap structure 512 is connected to the first snap structure 511, and a snap space 513 is formed between the second snap structure 512 and the first snap structure 511. The mating convex column 73 is located in the snap space 513. In this way, the above setting makes the structure of the driving part 51 simpler, easier to process and implement, and thus reduces the processing cost of the driving part 51.

[0051] Specifically, both the first snap structure 511 and the second snap structure 512 are columnar structures, and the central axes of the two columnar structures are arranged parallel to each other, so as to form a snap space therebetween to snap the mating convex column 73 and drive the mating convex column 73 to move, ensuring that the driving part 51 can drive the mating convex column 73 to move and improving the driving reliability of the driving part 51.

[0052] It should be noted that the structures of the first clamping structure 511 and the second clamping structure 512 are not limited to this. Optionally, the first clamping structure 511 and the second clamping structure 512 are clamping jaws.

[0053] As Figure 6 and Figure 9 shown, the driving assembly 50 further includes a mounting bracket 52 and a transmission shaft 53. Among them, the mounting bracket 52 is connected to the first clamping structure 511, and the second clamping structure 512 is connected to the first clamping structure 511 through the mounting bracket 52. The transmission shaft 53 is arranged on the mounting bracket 52, and the transmission shaft 53 is connected to the driving device, and the driving device drives the transmission shaft 53 to drive the mounting bracket 52 and the driving part 51 to rotate. In this way, the driving device drives the transmission shaft 53 to rotate, and the transmission shaft 53 drives the mounting bracket 52 and the driving part 51 to rotate, thereby making the movement of the driving assembly 50 easier and simpler, and reducing the operation difficulty.

[0054] Optionally, the driving device is a motor. The motor shaft is connected to the transmission shaft 53 to drive the transmission shaft 53 to rotate about its central axis. At the same time, the transmission shaft 53 drives the mounting bracket 52, the first clamping structure 511 and the second clamping structure 512 to rotate, so that the mating convex column 73 clamped between the first clamping structure 511 and the second clamping structure 512 can rotate together with the first clamping structure 511 and the second clamping structure 512 to realize the movement of the cleaning part 30.

[0055] As Figure 4 shown, the extending direction of the transmission shaft 53 is arranged perpendicular to the central axis of the cylindrical body 71. Specifically, the central axis of the mating convex column 73 is arranged perpendicular to the central axis of the cleaning part 30, and the extending direction of the first clamping structure 511 is arranged perpendicular to the extending direction of the transmission shaft 53. The above settings ensure that the transmission shaft 53 can drive the mating convex column 73 to move through the driving part 51, thereby improving the use reliability of the cleaning device.

[0056] In this embodiment, the mating convex column 73 extends along the radial direction of the cylindrical body 71, and the mating convex column 73 extends into the clamping space 513 to be clamped with at least one of the first clamping structure 511, the second clamping structure 512, and the mounting bracket 52. In this way, the above settings further improve the driving reliability of the driving assembly 50 for the mating convex column 73, so that the cleaning part 30 can move within a preset range, and also improve the use reliability of the cleaning device.

[0057] In this embodiment, the cylindrical body 71 has a first through-hole 711 for at least part of the driving assembly 50 to pass through. Specifically, there are three first through-holes 711, and the three first through-holes 711 are arranged at intervals in the circumferential direction of the cylindrical body 71. The transmission shaft 53 is arranged in the first through-hole 711. On the one hand, it avoids the movement interference between the transmission shaft 53 and the cylindrical body 71, which affects the normal use of the cleaning device and extends the service life of the cleaning device; on the other hand, it reduces the overall weight of the cleaning assembly, making it more labor-saving and easier for the driving assembly 50 to drive the cleaning assembly.

[0058] It should be noted that the number of the first through-holes 711 is not limited to this, as long as the cylindrical body 71 has a certain structural strength. Optionally, the first through-hole 711 is one, or two, or four, or more.

[0059] Optionally, the machine base 40 includes a machine base body 42. Among them, the first fitting portion 41 is arranged on the machine base body 42, and the first fitting portion 41 is snap-connected, or bonded, or tied, or connected by fasteners with the machine base body 42. In this embodiment, the cleaning device is installed in the air conditioner indoor unit through the machine base body 42, and the machine base body 42 has a plurality of screw holes for screws or bolts to pass through. After the screws or bolts pass through the plurality of screw holes, the cleaning device is fixed inside the air conditioner indoor unit. Specifically, the first fitting portion 41 is tied to the machine base body 42 to make the disassembly and assembly of the two easier and simpler, reducing the operation difficulty of the user and improving the user experience.

[0060] It should be noted that the structure of the first fitting portion 41 is not limited to this. Optionally, the first fitting portion 41 is made by machining the machine base body 42, that is, a groove is machined on the machine base body 42 to form the first fitting portion 41.

[0061] As Figure 10 shown, the machine base body 42 has a second through-hole 421 for the transmission shaft 53 to pass through. In this way, after the transmission shaft 53 passes through the second through-hole 421, it is connected to the driving device, and further makes the disassembly and assembly of the driving device and the transmission shaft 53 easier and simpler, reducing the disassembly and assembly difficulty.

[0062] As Figure 6As shown in the figure, when the cleaning unit 30 is at the highest position, the transmission shaft 53 rotates counterclockwise (clockwise). At this time, the cleaning unit 30 rotates around its own central axis by a preset angle to achieve circumferential liquid (cleaning agent) spraying at the highest position. When the second engaging portion 60 reaches the corner position of the first engaging portion 41, the transmission shaft 53 continues to rotate, driving the cleaning unit 30 to move downward along its own central axis to achieve liquid (cleaning agent) spraying at different distances. When the cleaning unit 30 reaches the lowest position, the transmission shaft 53 continues to rotate, and the cleaning unit 30 rotates clockwise (counterclockwise) to achieve circumferential liquid (cleaning agent) spraying at the lowest position. According to the above movement process, when the transmission shaft 53 rotates one week, the cleaning unit 30 returns to the initial position. Among them, during the process of the transmission shaft 53 rotating one week, the distribution of the hole-shaped structure 31 of the cleaning unit 30 is as Figure 7 shown.

[0063] As Figure 1 shown, the present application also provides an air conditioner indoor unit, including a housing 80, a volute 20, an evaporator 90, a blower fan 10, and a cleaning device. The volute 20, the evaporator 90, the blower fan 10, and the cleaning device are all located inside the housing 80. The volute 20 has a through hole for the cleaning unit 30 of the cleaning device to pass through. Among them, the cleaning device is the above-mentioned cleaning device.

[0064] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0065] The cleaning device cleans the blower fan and / or the volute of the air conditioner indoor unit. The base includes a first engaging portion, and the first engaging portion is surrounded by multiple sub-engaging portions. In this way, when the cleaning unit of the component to be cleaned sprays liquid or gas onto the blower fan and / or the volute, the driving component is started to drive the cleaning component to move. The second engaging portion of the cleaning component cooperates with the first engaging portion of the base and slides along each sub-engaging portion in sequence, so that the cleaning unit moves within a preset trajectory, and thus the cleaning unit can clean the blower fan and / or the volute sufficiently, solving the problem in the prior art that the cleaning of the air conditioner indoor unit is not in place and affecting the user experience, improving the cleanliness of the blower fan and / or the volute, and improving the user experience.
