Abstract
Description
Technical Field
[0001] This utility model relates to the field of central air conditioning technology, and in particular to a self-cleaning mechanism for central air conditioning. Background Technology
[0002] Central air conditioning is an air conditioning system that centralizes the air conditioning system in one place and delivers cold or hot air to different rooms through pipes. It is commonly used in large buildings, office buildings, hotels, and some residences. As people's requirements for indoor air quality continue to increase, the performance and maintenance management of central air conditioning, as a widely used air conditioning system in commercial and residential buildings, are receiving more and more attention. Therefore, a self-cleaning mechanism for central air conditioning is needed.
[0003] Traditional central air conditioning systems typically do not have cleaning mechanisms during operation. Over long periods of use, pollutants such as dust, bacteria, and mold can accumulate on the surfaces of components like ducts and air guide vanes. This accumulated dirt and bacteria can be circulated into the indoor air, leading to a decline in air quality and affecting users' health and comfort. To ensure air quality, the central air conditioning system needs to be cleaned manually and regularly, which is time-consuming and reduces work efficiency. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a self-cleaning mechanism for central air conditioning systems.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A self-cleaning mechanism for central air conditioning includes a central air conditioning duct. An air outlet is installed on the side wall of one end of the duct, and a guide vane is installed on the inner side wall of the air outlet. A rectangular frame is slidably connected to the inner side wall of the central air conditioning duct, and the rectangular frame is adapted to the central air conditioning duct. A first moving mechanism for moving the rectangular frame is provided on the inner side wall of the central air conditioning duct. A cleaning brush is slidably connected to the inner side wall of the guide vane. A second moving mechanism for moving the cleaning brush is provided inside the central air conditioning duct. A dust collection mechanism is provided on the inner side wall of the rectangular frame. During use, the first moving mechanism drives the rectangular frame to reciprocate along the inner wall of the central air conditioning duct, and the second moving mechanism drives the cleaning brush to reciprocate along the inner wall of the guide vane. This allows for simultaneous cleaning of both the central air conditioning duct and the guide vane, eliminating the need for regular manual cleaning, saving time, and improving work efficiency. The collection mechanism automatically collects the cleaned dust, effectively preventing dust redistribution, reducing the need for secondary cleaning, and improving the practicality of the device.
[0007] As a further embodiment of this utility model, the first moving mechanism includes four first support plates, which are fixed in pairs to the inner walls of both ends of the central air conditioning duct. The same first reciprocating screw is rotatably connected to the inner walls of every two first support plates, and one end of each of the two first reciprocating screws passes through the outer walls of two of the first support plates. A motor is fixed to the outer wall of the other first support plate, and the output shaft of the motor is fixed to one of the first reciprocating screws. A first screw sleeve is fitted onto the side walls of both first reciprocating screws, and pin holes are provided radially on the inner circumferential surfaces of both first screw sleeves. The hole is equipped with crescent pins that mate with two first reciprocating lead screws. The two first lead screw sleeves are fixed to the inner walls of the two ends of the rectangular frame. One end of each of the two first reciprocating lead screws is fitted with a synchronous pulley. The inner wall of the central air conditioning duct is rotatably connected to a synchronous belt. The two ends of the synchronous belt are respectively fitted onto the side walls of the two synchronous pulleys. The drive motor drives one of the first reciprocating lead screws to rotate, which, together with the synchronous belt and the two synchronous pulleys, drives the other first reciprocating lead screw to rotate. The two first reciprocating lead screws rotate simultaneously, and together with the two first lead screw sleeves, they drive the rectangular frame to move back and forth along the inner wall of the central air conditioning duct, which can clean the dust around the inner wall of the central air conditioning duct.
[0008] As a further embodiment of this utility model, the second moving mechanism includes two second support plates, which are fixed to the top sides of the central air conditioning duct. A sliding rod is fixed to the inner sidewall of each of the two second support plates. A second lead screw is rotatably connected to the inner sidewall of each of the two second support plates, with one end of the lead screw penetrating the outer sidewall of one of the second support plates. A second lead screw sleeve is fitted onto the sidewall of the second lead screw, and the second lead screw sleeve and the sliding rod are slidably connected. A pin hole is provided radially on the inner circumferential surface of the second lead screw sleeve, and a crescent pin that cooperates with the second lead screw is provided in the pin hole. The second lead screw sleeve and the cleaning brush are fixed. A second bevel gear is fitted onto one end of the second lead screw, and a first bevel gear is fitted onto one end of one of the first reciprocating lead screws. The first bevel gear and the second bevel gear mesh. Rotation of the first reciprocating lead screw drives the first bevel gear to rotate, which in turn drives the second lead screw to rotate. The rotation of the second lead screw, in conjunction with the sliding rod and the second lead screw sleeve, drives the cleaning brush to reciprocate along the inner sidewall of the air guide vane, cleaning the dust on the surface of the air guide vane.
[0009] As a further embodiment of this utility model, the collection mechanism includes a connecting plate fixed to the side wall of a rectangular frame. A vacuum cleaner is mounted on the top of the connecting plate, and a first connecting pipe is installed at the dust inlet of the vacuum cleaner. A second connecting pipe is fixed to the inner side wall of the rectangular frame, and the first and second connecting pipes are connected. Multiple air inlets are fixed linearly at equal intervals on the second connecting pipe. The vacuum cleaner is driven to work with the first connecting pipe to evacuate the air inside the second connecting pipe, creating a negative pressure environment inside the second connecting pipe. At this time, the cleaned dust enters the second connecting pipe through the multiple air inlets and is collected inside the vacuum cleaner through the first connecting pipe, preventing the cleaned dust from scattering and requiring secondary cleaning, thus improving the practicality of this device.
[0010] As a further embodiment of this utility model, a limiting frame is fixed on the inner wall of the central air conditioning duct near the air outlet. The limiting frame can limit the air guide blades, making it convenient to install the air guide blades.
[0011] The beneficial effects of this utility model are as follows:
[0012] 1. During use, the first moving mechanism drives the rectangular frame to move back and forth along the inner wall of the central air conditioning duct, and the second moving mechanism drives the cleaning brush to move back and forth along the inner wall of the air guide blade. The central air conditioning duct and the air guide blade can be cleaned at the same time, eliminating the need for regular manual cleaning, saving time and improving work efficiency.

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Reference Figure 1 - Figure 4 A self-cleaning mechanism for central air conditioning includes a central air conditioning duct 1, an air outlet 2 installed on one end of the side wall of the central air conditioning duct 1, and a guide vane 3 installed on the inner side wall of the air outlet 2. A rectangular frame 8 is slidably connected to the inner side wall of the central air conditioning duct 1, and the rectangular frame 8 is adapted to the central air conditioning duct 1. The rectangular frame 8 can reciprocate on the inner wall of the duct, thereby achieving comprehensive cleaning of the inner wall of the duct. The inner side wall of the central air conditioning duct 1 is provided with a first moving mechanism for moving the rectangular frame 8. A cleaning brush 21 is slidably connected to the inner side wall of the guide vane 3. The flexibility of the cleaning brush 21 allows it to adapt to the shape of the guide vane 3, penetrate into gaps and curved surfaces, and thus more thoroughly clean dust. The central air conditioning duct 1 is equipped with a second moving mechanism for moving the cleaning brush 21, and the inner wall of the rectangular frame 8 is equipped with a dust collection mechanism. During use, the first moving mechanism drives the rectangular frame 8 to move back and forth along the inner wall of the central air conditioning duct 1, and the second moving mechanism drives the cleaning brush 21 to move back and forth along the inner wall of the air guide vane 3. The central air conditioning duct 1 and the air guide vane 3 can be cleaned at the same time, eliminating the need for regular manual cleaning, saving time and improving work efficiency. The dust collected by the collection mechanism can be automatically collected, which can effectively prevent the dust from spreading again, reduce the need for secondary cleaning, and improve the practicality of the device.
[0021] In this embodiment, the first moving mechanism includes four first support plates 5. The four first support plates 5 are fixed in pairs to the inner walls of both ends of the central air conditioning duct 1. The inner walls of every two first support plates 5 are rotatably connected to the same first reciprocating screw 6, and one end of each of the two first reciprocating screws 6 passes through the outer walls of two of the first support plates 5. A motor 7 is fixed to the outer wall of the other first support plate 5, and the output shaft of the motor 7 is fixed to one of the first reciprocating screws 6. The side walls of the two first reciprocating screws 6 are each fitted with a first screw sleeve 23. The inner circumferential surface of the two first screw sleeves 23 is provided with pin holes along its radial direction. The two pin holes are respectively provided with crescent pins that cooperate with the two first reciprocating screws 6, and the two first screw sleeves 23 are respectively rectangular frames 8. The inner walls at both ends are fixed, and one end of each of the two first reciprocating screws 6 is fitted with a synchronous pulley 14. A synchronous belt 15 is rotatably connected to the inner wall of the central air conditioning duct 1. The two ends of the synchronous belt 15 are respectively fitted onto the side walls of the two synchronous pulleys 14. The synchronous belt 15 is connected to the two synchronous pulleys 14 to ensure that the two first reciprocating screws 6 can move synchronously and prevent the rectangular frame 8 from getting stuck at one end. The drive motor 7 drives one of the first reciprocating screws 6 to rotate, which, together with the synchronous belt 15 and the two synchronous pulleys 14, drives the other first reciprocating screw 6 to rotate. The two first reciprocating screws 6 rotate at the same time, which, together with the two first screw sleeves 23, drives the rectangular frame 8 to move back and forth along the inner wall of the central air conditioning duct 1, which can clean the dust around the inner wall of the central air conditioning duct 1.
[0022] In this embodiment, the second moving mechanism includes two second support plates 17, which are fixed to the top sides of the central air conditioning duct 1. The inner sidewalls of the two second support plates 17 are fixed with the same slide rod 18. The inner sidewalls of the two second support plates 17 are rotatably connected to the same second lead screw 19, with one end of the second lead screw 19 penetrating the outer sidewall of one of the second support plates 17. A second lead screw sleeve 20 is fitted onto the sidewall of the second lead screw 19, and the second lead screw sleeve 20 and the slide rod 18 are slidably connected. A pin hole is provided radially on the inner circumferential surface of the second lead screw sleeve 20, and a crescent pin that mates with the second lead screw 19 is provided in the pin hole. The second lead screw sleeve 20 and the cleaning brush 21 are fixed together, and one end of the second lead screw 19 is sleeved with... The second bevel gear 22 has a first bevel gear 16 sleeved at one end of the first reciprocating screw 6, and the first bevel gear 16 and the second bevel gear 22 mesh. The design of the first bevel gear 16 and the second bevel gear 22 allows for a change in the direction of rotation. In this way, the rotation of the first reciprocating screw 6 can be effectively converted into the rotation of the second screw 19, ensuring that the cleaning brush 21 can reciprocate along the inner wall of the air guide vane 3. The rotation of the first reciprocating screw 6 drives the rotation of the first bevel gear 16, which in turn drives the rotation of the second bevel gear 22 to drive the rotation of the second screw 19. The rotation of the second screw 19, in conjunction with the slide rod 18 and the second screw sleeve 20, drives the cleaning brush 21 to reciprocate along the inner wall of the air guide vane 3 to clean the dust on the surface of the air guide vane 3.
[0023] In this embodiment, the collection mechanism includes a connecting plate 9, which is fixed to the side wall of a rectangular frame 8. A vacuum cleaner 10 is installed on the top of the connecting plate 9. A first connecting pipe 11 is installed at the dust inlet of the vacuum cleaner 10. A second connecting pipe 12 is fixed to the inner side wall of the rectangular frame 8, and the first connecting pipe 11 and the second connecting pipe 12 are connected. Multiple air inlets 13 are fixed linearly at equal intervals on the second connecting pipe 12. The vacuum cleaner 10 is driven to work with the first connecting pipe 11 to perform air extraction on the inside of the second connecting pipe 12, so that the inside of the second connecting pipe 12 is a negative pressure environment. At this time, the dust that is cleaned out enters the inside of the second connecting pipe 12 through the multiple air inlets 13 and enters the vacuum cleaner 10 through the first connecting pipe 11 to be collected, preventing the cleaned dust from scattering everywhere and requiring secondary cleaning, thus improving the practicality of this device.
[0024] In this embodiment, a limiting frame 4 is fixed on the inner wall of the central air conditioning duct 1 near the air outlet 2. The limiting frame 4 can limit the air guide blade 3, making it convenient to install the air guide blade 3.
[0025] The working principle of this embodiment is as follows: During use, when it is necessary to clean the central air conditioning duct 1 and the air guide vanes 3, the power switch of the motor 7 is first turned on. The motor 7 drives one of the first reciprocating lead screws 6 to rotate, which, together with the synchronous belt 15 and two synchronous pulleys 14, drives the other first reciprocating lead screw 6 to rotate. The two first reciprocating lead screws 6 rotate simultaneously, which, together with the two first lead screw sleeves 23, drives the rectangular frame 8 to move back and forth along the inner wall of the central air conditioning duct 1, thus cleaning the dust around the inner wall of the central air conditioning duct 1. At the same time, the rotation of one of the first reciprocating lead screws 6 drives the first bevel gear 16 to rotate, which, together with the second bevel gear 22, drives the second lead screw 19 to rotate. The rotation of the second lead screw 19, together with the slide rod 18 and the second lead screw slide rod, drives the first bevel gear 16 to rotate. The sleeve 20 drives the cleaning brush 21 to move back and forth along the inner wall of the air guide vane 3 to clean the dust on the surface of the air guide vane 3, preventing the air quality from deteriorating, thereby improving the user's health and comfort. It also eliminates the need for regular manual cleaning, saving time and improving work efficiency. While cleaning, the power switch of the vacuum cleaner 10 is turned on, driving the vacuum cleaner 10 to work with the first connecting pipe 11 to evacuate the inside of the second connecting pipe 12, creating a negative pressure environment inside the second connecting pipe 12. At this time, the cleaned dust enters the inside of the second connecting pipe 12 through multiple air inlets 13 and enters the vacuum cleaner 10 through the first connecting pipe 11 to be collected, preventing the cleaned dust from scattering everywhere and requiring secondary cleaning, thus improving the practicality of this device.
