Description

Technical Field

[0001] This invention relates to the field of air conditioning maintenance technology, and in particular to a dust removal device for the condenser of an air conditioner outdoor unit. Background Technology

[0002] A condenser is a component of a refrigeration system and a type of heat exchanger. It converts gas or vapor into liquid and quickly transfers heat from the pipes to the air near the pipes. The condenser operates by releasing heat, so its temperature is always relatively high. As the core heat dissipation component of the outdoor unit of an air conditioner, the efficient operation of the condenser directly affects the overall cooling performance.

[0003] Because this equipment is exposed to a complex outdoor environment for extended periods, the air is constantly in motion, and the wind continuously blows up and carries dust, pollen, soil particles, and other impurities from the surrounding environment. When this dusty air flows through the condenser of the air conditioner's outdoor unit, the dust comes into contact with the condenser surface with the airflow and gradually adheres to it. These deposits not only form a physical insulation layer but also drastically reduce the effective heat dissipation area. The surface of the pipes, which should be in full contact with the air for heat exchange, is blocked by dust, significantly reducing heat dissipation efficiency and worsening the air conditioner's cooling effect. To ensure the condenser's heat dissipation effect, the outdoor unit is often cleaned periodically. Existing methods often involve water or air jets to impact the condenser (which is mainly composed of condenser tubes and heat dissipation fins) and remove dust from its surface. However, existing dust removal devices are relatively ineffective. Summary of the Invention

[0004] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. An embodiment of the present invention provides a dust removal device for the condenser of an air conditioner outdoor unit, thereby solving the problem of poor dust removal performance in existing air conditioner outdoor unit condensers.

[0005] The present invention adopts the following technical solution: a dust removal device for the condenser of an air conditioner outdoor unit, including heat dissipation fins placed inside the condenser for auxiliary heat dissipation, and further comprising; The multi-functional cleaning mechanism is located inside the condenser and positioned on both sides of the heat dissipation fins. The multi-functional cleaning mechanism is applicable to heat dissipation fins of various shapes and can effectively remove dust accumulated on the surface of the heat dissipation fins. A drive mechanism, located inside the condenser, enables the multi-functional cleaning mechanism to move up and down.

[0006] Furthermore, the drive mechanism includes a transmission assembly and a connecting base. The transmission assembly is connected to the connecting base and has a transmission belt inside for vertical movement. An air pump is provided on the outside of the connecting base, and the air pump delivers gas through multiple air supply pipes.

[0007] Furthermore, the multifunctional cleaning mechanism includes a cleaning component and a recycling component. The cleaning component includes a cleaning box, the inner side of which is connected to an air supply pipe. The air outlet of the air supply pipe inside the cleaning box is tapered to improve the uniformity of air output. The cleaning box has several through holes on the side that is in contact with the heat dissipation fins, and the distribution of the through holes corresponds to the distribution of several fins in the heat dissipation fins. Several cleaning balls are distributed inside the cleaning component.

[0008] Furthermore, the shape of the cleaning box is adapted to the shape of the heat dissipation fins, and is either L-shaped or I-shaped.

[0009] Furthermore, the recycling assembly includes a recycling box located on the other side of the heat sink fins and opposite to the cleaning box. The cleaning box has a recycling groove on the side in contact with the heat sink fins. Inside the cleaning box, from top to bottom, there are an inclined block, a friction plate, a cleaning base plate, and a guide plate. The inclined block is located below the recycling groove. A connecting pipe is provided at the lowest point of the vertical connecting block. The connecting pipe is connected to the cleaning box at another location. The friction plate and the cleaning base plate are slidably connected by a horizontal connecting block. One side of the friction plate is connected to a vibrator via a vertical connecting block. The vibrator drives the horizontal connecting block to move back and forth.

[0010] Furthermore, the width of the friction plate is smaller than the width of the cleaning base plate, and the cleaning base plate has several holes. The surface of the friction plate is made of felt material.

[0011] Furthermore, the cleaning ball is made of a material with a certain degree of hardness that can carry a negative charge, such as silicone balls and rubber balls.

[0012] Furthermore, the diameter of the holes made on the cleaning plate matches the diameter of the cleaning ball.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: Firstly, this solution has a wider range of applications compared to existing solutions. Existing refrigeration unit dust removal mechanisms generally have a brush that can move up and down on the surface of the condenser to clean the condenser fins. However, in order to improve the condensing effect, existing air conditioner condensers are L-shaped (i.e., the entire back and part of the side). In this case, the existing brush cannot clean the condenser with this layout. The multi-functional cleaning mechanism in this solution can effectively clean the fins in different states, thereby effectively improving adaptability. Secondly, during the dust removal process, the system uses a multi-functional recycling mechanism to directionally spray several cleaning balls onto the target area (such as air conditioner condenser fins, heat exchanger surfaces, and precision equipment heat dissipation fins). Under the control of the mechanism, these cleaning balls precisely contact the edges of the fins or areas with dense dust accumulation at a certain speed and angle. Through a combination of physical impact, rolling, and friction, they efficiently peel off and loosen the dust, oil, impurities, and other contaminants attached to the edges of the fins. Compared to traditional one-way direct jet cleaning methods (such as relying solely on high-speed airflow generated by a fan), this solution has the following significant advantages: Stronger physical impact: The cleaning ball, through direct contact and impact with the fin edges, effectively breaks the adhesion between dust and the fins, especially effectively loosening dense, compacted, and tightly adhered dust; More precise cleaning: The cleaning ball can be designed to target blind spots that airflow cannot reach, such as edges, gaps, and stacked areas, achieving targeted cleaning and higher cleaning coverage; Multi-mechanism combined action: The cleaning ball, while impacting, combines rolling, friction, adhesion, or electrostatic adsorption to further enhance its ability to capture and remove dust; Reduced dust and secondary pollution: Compared to direct jets that may scatter dust and cause secondary adhesion, the cleaning ball controls the direction of dust through physical contact, making it easier to achieve directional cleaning and collection; Scalable to automated or intelligent systems: The cleaning ball can also be de-dusted after adsorbing dust, making it reusable. In summary, the cleaning mechanism in this solution is applicable to different heat sink fins, and it achieves better dust removal results compared to simply blowing or sucking.

[0017] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] The following is combined Figures 1 to 7 As shown, this embodiment of the invention provides a condenser dust removal device for an air conditioner outdoor unit, including heat dissipation fins 1 placed inside the condenser for auxiliary heat dissipation, and also includes; The multi-functional cleaning mechanism is located inside the condenser and placed on both sides of the heat dissipation fins 1. The multi-functional cleaning mechanism is applicable to heat dissipation fins 1 of various shapes and can effectively remove the dust accumulated on the surface of the heat dissipation fins 1. The drive mechanism 2 is located inside the condenser, and the multi-functional cleaning mechanism can move up and down through the drive mechanism 2.

[0023] Specifically, the drive mechanism 2 includes a transmission component 21 and a connecting base 22. The transmission component 21 is connected to the connecting base 22 and has a transmission belt inside for vertical movement. An air pump 24 is provided on the outside of the connecting base 22, and the air pump 24 delivers gas through multiple air supply pipes 23.

[0024] During operation, it should be noted that the transmission assembly 21 includes two sets of rotating shafts and a transmission belt. The transmission belt has protrusions that are connected to the cleaning box 31. One of the rotating shafts is connected to the drive motor (using a forward and reverse motor), and the other is placed in the transmission assembly 21. The rotation of the drive motor drives the rotating shaft to rotate, which in turn drives the transmission belt to move. The movement of the transmission belt drives the protrusion to move, which in turn drives the cleaning box 31 to move, thus enabling it to move up and down, minimizing the obstruction of the heat dissipation fins 1 and avoiding affecting heat dissipation.

[0025] Specifically, the multifunctional cleaning mechanism includes a cleaning component and a recycling component. The cleaning component includes a cleaning box 31, the inner side of which is connected to an air supply pipe 23 (using a flexible hose). The air outlet of the air supply pipe 23 inside the cleaning box 31 is tapered to improve the uniformity of air output. The cleaning box 31 has several through holes 311 on the side that is in contact with the heat dissipation fins 1. The distribution of the through holes 311 corresponds to the distribution of several fins in the heat dissipation fins 1. Several cleaning balls are distributed inside the cleaning component.

[0026] Specifically, the shape of the cleaning box 31 is adapted to the shape of the heat dissipation fins 1, and is L-shaped or I-shaped.

[0027] During operation, the cleaning box 31 can effectively wrap around the heat dissipation fins 1.

[0028] Specifically, the recycling assembly includes a recycling box 33, which is located on the other side of the heat dissipation fins 1 and opposite to the cleaning box 31. The cleaning box 31 has a recycling groove 331 on the side in contact with the heat dissipation fins 1. Inside the cleaning box 31, from top to bottom, are arranged an inclined block 332, a friction plate 336, a cleaning base plate 335, and a guide plate 334. The inclined block 332 is located below the recycling groove 331. A connecting pipe 32 is located at the lowest point of the vertical connecting block 338. The connecting pipe 32 is connected to the cleaning box 31 at another location. To prevent the cleaning balls from being affected by rising gas and instead entering the cleaning box 33 from the connecting pipe 32, a one-way valve can be installed at the opening between the cleaning box 31 and the connecting pipe 32 to restrict the flow direction. The friction plate 336 and the cleaning base plate 335 are slidably connected by a transverse connecting block 3310. A horizontal connecting block 3310 is provided between the wiping plate 336 and the cleaning base plate 335, allowing them to be removed synchronously from the side wall of the recycling box 33. One side of the wiping plate 336 is connected to the vibrator 337 via a vertical connecting block 338. The vibrator 337 drives the vertical connecting block 338, which in turn drives the wiping plate 336 to move back and forth (it should be noted that back and forth movement here refers to shaking forward and backward, not moving left and right). At the same time, the fixed end of the vibrator 337 is fixedly connected to the side wall of the recycling box 33, while the vibrating end of the vibrator 337 is connected to the vertical connecting block 338. The cleaning base plate 335 is connected to the side wall of the recycling box 33 via a T-shaped key. Similarly, the vertical connecting block 338 and the wiping plate 336 can also be connected by a T-shaped connection. The wiping plate 336 is provided with a vertical groove 339, which is used to connect the vertical connecting block 338.

[0029] At this point, it is necessary to add an explanation: during use, the distribution position of the cleaning box 31 can be oriented towards the inner side, so that it can be easily removed from the observation port 333 when the bottom plate 335 and friction plate 336 need to be removed for cleaning later.

[0030] Specifically, the friction plate 336 is narrower than the cleaning base plate 335, and the cleaning base plate 335 has several holes. The surface of the friction plate 336 is made of felt material.

[0031] By rubbing back and forth, an electric charge can be applied to the surface of the cleaning ball, so that it can be used with static electricity during the cleaning process. Secondly, the friction can also process the dust on its surface and transfer it to the felt surface, making it easier to collect and process the dust later.

[0032] Specifically, the cleaning ball is made of a material with a certain hardness that can carry a negative charge, such as silicone balls and rubber balls. In order to improve the cleaning ability of the cleaning ball, the surface is also selected to have several protrusions.

[0033] By using a cleaning ball carrying a negative charge, it can loosen dust upon contact with it during flight. The loosened dust can then be adsorbed by the surface of the cleaning ball. Considering that some dust may adhere significantly, an inclined guide plate 334 is installed between the collection box 33 and the connecting pipe 32. This allows the falling cleaning ball to land on the guide plate 334 and then pass through the connecting pipe 32 into the cleaning box 31. During operation, considering the need for the cleaning ball to be transported back and forth, its weight should not be too heavy. Therefore, the cleaning ball adopts a hollow structure. Furthermore, to ensure easy transport, a negative pressure suction device can be installed at the end of the connecting pipe 32, thereby improving the mobility of the cleaning ball.

[0034] Specifically, the holes made on the base plate 335 are removed, and their diameter matches that of the cleaning ball.

[0035] Working principle: The operation is divided into a cleaning section and a recycling section, explained separately. After the condenser is installed, the multi-functional cleaning mechanism is also installed. The drive mechanism 2 is then activated, and the transmission component 21 moves, causing the cleaning box 31 to move synchronously. The cleaning box 31 and the recycling box 33 are connected by a connecting pipe 32, so the recycling box 33 moves synchronously with the cleaning box 31. During the cleaning process, air is supplied by the air pump 24, and the air enters the cleaning box 31 through the air supply pipe 23. The air pressure forces the cleaning balls inside the cleaning box 31 out through the through-hole 311. Under the control of the mechanism, these cleaning balls move precisely at a certain speed and angle. The cleaning ball is designed to effectively remove and loosen dust, oil, impurities, and other contaminants attached to the fin edges or areas with dense dust accumulation through a combination of physical impact, rolling, and friction. Simultaneously, the negative charge carried by the cleaning ball causes dust to loosen during its flight. The loosened dust is then adsorbed by the surface of the cleaning ball. Considering that some dust may adhere heavily, an inclined guide plate 334 is installed between the recycling box 33 and the connecting pipe 32, allowing the falling cleaning ball to land on the guide plate 334 and then enter the cleaning box 31 through the connecting pipe 32. The cleaning balls entering the recycling bin 33 fall onto the cleaning base plate 335 via the inclined block 332. At this time, the friction plate 336 on the cleaning base plate 335 moves back and forth under the action of the vibrator 337. Because dust adheres to the surface of the cleaning balls, they cannot effectively fall through the holes. The back-and-forth movement of the friction plate 336 causes the cleaning balls to move back and forth (the gap between the friction plate 336 and the cleaning base plate 335 is slightly larger than the diameter of the friction balls). Through the back-and-forth movement of the friction plate 336, combined with its felt material, the dust on the surface of the friction balls can be transferred. At the same time, it can also partially press the friction ball, so that the friction ball will fall into the guide plate 334 through the hole, and then fall into the opening of the connecting pipe 32 through the guide plate 334. Then, through negative pressure adsorption, the cleaning ball enters the cleaning box 31 through the connecting pipe 32 for circulation. Meanwhile, the cleaning box 31 moves up and down under the transmission component 21 to ensure overall dust removal of the heat dissipation fins 1. When it needs to be removed, the friction plate 336 is pulled through the observation port 333. The friction plate 336 drives the cleaning base plate 335 to move synchronously through the horizontal connecting block 3310.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
