Description

Technical Field

[0001] The present invention relates to the technical field of condenser dust removal, and in particular to a dust removal device for an outdoor unit condenser of an air conditioner. Background Art

[0002] The condenser is a component of the refrigeration system and a type of heat exchanger. It can convert gas or steam into liquid and transfer the heat in the pipe to the air near the pipe in a very fast way. The working process of the condenser is an exothermic process, so the condenser temperature is relatively high.

[0003] A Chinese patent with authorization announcement number CN117469733B discloses a dust removal device for an air conditioner outdoor unit condenser, comprising: a supporting material receiving mechanism, a guide lifting mechanism installed inside the supporting material receiving mechanism, a roller brush mechanism installed inside the guide lifting mechanism, a condenser body fixedly installed inside the supporting material receiving mechanism, and the condenser body is located inside the guide lifting mechanism, a lifting drive mechanism is installed on one side of the guide lifting mechanism, and an air pumping mechanism is provided on the other side of the guide lifting mechanism, and an air guide mechanism is provided at the output end of the air pumping mechanism. The dust removal device for the air conditioner outdoor unit condenser can drive the roller brush mechanism to rise and fall through the lifting drive mechanism, and the rotation generated by the lifting of the roller brush mechanism forms a brushing motion to clean the dust on the surface of the condenser body, and the air pumping mechanism pumps air through the air guide mechanism to flush the surface of the condenser body, thereby ensuring that the surface of the condenser body remains clean.

[0004] As the core heat dissipation component of the air conditioner's outdoor unit, the efficient operation of the air conditioner condenser is directly related to the overall cooling performance. Due to the long-term exposure of this equipment to complex outdoor environments, a large amount of dust and impurities are easily deposited on the inside of the condenser. These attachments not only form a physical insulation layer, but also lead to a sharp decrease in the effective heat dissipation area. The surface of the pipes that should be fully exposed to the air for heat exchange is blocked by dust, and the heat loss efficiency is greatly reduced, resulting in a poor cooling effect of the air conditioner. In the above technical solution, airflow is used to flush both sides of the condenser simultaneously. Due to the large number of pipes running through the condenser, this method may cause impurities to remain in the middle of the condenser or adhere to the pipes, making it impossible to effectively remove them, resulting in unsatisfactory cleaning results. Summary of the Invention

[0005] The present invention provides a dust removal device for the condenser of an air conditioner outdoor unit, which aims to solve the problem in the related technology that a large amount of dust and impurities are easily deposited on the inner side of the condenser due to the long-term exposure of the equipment to a complex outdoor environment.

The surface of the pipe that should have been in full contact with the air for heat exchange is blocked by dust, and the heat loss efficiency is greatly reduced, which makes the cooling effect of the air conditioner worse. In the above technical solution, air flow is used to flush both sides of the condenser at the same time. Since there are many pipes running through the inside of the condenser, this method may cause impurities to stay in the middle position of the condenser or adhere to the pipes, and cannot be effectively removed, resulting in a technical problem of unsatisfactory cleaning effect.

[0011] Preferably, the combing frame is U-shaped and has two side panels and a horizontal panel. The side panels of the combing frame are provided with guide grooves that pass through the left and right sides. The guide grooves are inclined, and the connecting shaft on the brush roller passes through the guide grooves. The connecting shaft cooperates with the groove wall of the guide groove.

[0012] The effect is that the combing frame can be forced to move up and down by sliding the carrier frame forward and backward, so as to clean the debris on the comb teeth.

[0013] Preferably, a plane is provided on the outer peripheral wall of the brush roller, and the air holes are provided on the plane, and the air holes are provided in multiple rows.

[0020] By adopting the above technical solution, the beneficial effects of the present invention are as follows: when the condenser needs to be dusted, the lifting seat drives the front and rear brush rollers to descend simultaneously. When the pressure sensor on one side of the support frame contacts the horizontal section of the pipe, the lifting seat temporarily stops descending. After the pressure sensor on the side contacting the pipe detects a signal, the limit block extends and is inserted into the limit groove, restricting the rotation of the brush roller, and the air holes continuously blow air toward the condenser. As the brush roller continues to descend, since the horizontal sections of the pipe are staggered front and back in the vertical direction, the air holes on one side are always kept blowing air toward the condenser, blowing the dust to the other side, while the brush roller on the other side continuously rotates to clean the dust attached to the condenser on that side. The support frames on the front and rear sides are alternately in contact with the horizontal section of the pipe, blowing the dust inside the condenser to one side. At the same time, the rotating brush roller on the other side can not only clean the dust on the side wall of the condenser, but also block the blown dust to prevent the dust from floating inside the external unit casing after being blown out, and finally causing the dust to fall back on the condenser. It can effectively clean the dust attached to the condenser and avoid dust residue on the pipe inside the condenser. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0035] like Figures 1 to 11 As shown, a specific embodiment of a dust removal device for an outdoor unit condenser of an air conditioner according to the present invention includes an outdoor unit housing 10, a dust removal module and a cleaning module.

[0036] like Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4 As shown, a condenser 11 is fixedly installed in the outer casing 10, and a pipe 12 is installed on the condenser 11. The pipe 12 has a serpentine structure, and all horizontal sections on the pipe 12 pass through the condenser 11 from left to right, and all horizontal sections are staggered in the vertical direction (such as Figure 4 As shown). That is, the portion connecting the ends of two adjacent horizontal sections is inclined. The installation structure of the pipe 12 on the condenser 11 belongs to the prior art and will not be described in detail here.

[0037] The outer housing 10 is also provided with other structures such as fan blades, a compressor, and a controller. These structures belong to the existing technology and are therefore not described in detail.

[0038] The dust removal module includes a lifting mechanism and a dust removal mechanism, such as Figure 2 and Figure 5 As shown, the lifting unit includes a screw rod 20 rotatably installed in the outer housing 10. The screw rod 20 is arranged vertically and is located near the left side of the outer housing 10. A motor (not shown in the figure) is installed at one end of the screw rod 20 to drive it to rotate.

[0039] A lifting base 21 is threaded onto the screw rod 20 and extends vertically through the lifting base 21. The lifting base 21 vertically slides against the inner wall of the outer housing 10. Rotation of the screw rod 20 causes the lifting base 21 to rise and fall. It is particularly important to note that both the screw rod 20 and the lifting base 21 are located on the left side of the condenser 11.

[0040] The dust removal mechanism is installed on the lifting seat 21 , and two dust removal mechanisms are symmetrically arranged front and back. Each dust removal mechanism includes a dust removal unit and a driving unit. The dust removal units in the two dust removal mechanisms are respectively arranged on the front and back sides of the condenser 11 .

[0041] like Figure 5 and Figure 7 As shown, the driving unit includes a driving motor 22 , a driving wheel 23 , a transmission wheel 24 , a transmission belt 25 and teeth 26 .

[0042] A drive motor 22 is fixedly mounted on the top surface of the lift base 21. A drive wheel 23 is fixedly mounted on the output end of the drive motor 22. A transmission wheel 24 is rotatably mounted on the right side of the lift base 21. The transmission wheel 24 rotates along an axis extending in the left-right direction, and the axis of the transmission wheel 24 and the axis of the drive wheel 23 are maintained parallel. The transmission wheel 24 and the drive wheel 23 are connected by a transmission belt 25. When the drive motor 22 drives the drive wheel 23 to rotate, the drive wheel 23 can also drive the transmission wheel 24 to rotate.

[0043] It should be noted that, in this embodiment, the driving wheel 23 and the transmission wheel 24 are both synchronous pulleys, and the transmission belt 25 is a synchronous belt.

[0044] The transmission wheel 24 has a through hole extending therethrough from side to side. The through hole is coaxial with the transmission wheel 24 , and a plurality of teeth 26 are provided on the inner side wall of the through hole along its circumference.

[0045] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 as well as Figure 10 As shown, the dust removal unit includes a sliding seat 30, a carrier frame 31, a connecting part 32, a mounting part 33, a bracket 35, an air inlet pipe 36, a limit block 38, a pressure sensor 39, a brush roller 40, a guide column 42, a connecting shaft 43, a telescopic gear 44, a telescopic tooth 45 and a ventilation pipe 47.

[0046] The sliding seat 30 is mounted on the lifting seat 21 for horizontal sliding movement in the forward and backward directions. The sliding seats 30 in the front and rear dust removal mechanisms are respectively slidably mounted on the front and rear sides of the lifting seat 21. The lifting seat 21 is provided with a drive member (not shown) that drives the sliding seat 30 to slide forward and backward. This drive member can be a cylinder or a screw structure.

[0047] A carrier 31 is fixedly mounted on the sliding seat 30. The carrier 31 is U-shaped and has a connecting portion 32 and two mounting portions 33. The mounting portions 33 are located on two opposing panels of the carrier 31, while the bottom plate of the carrier 31 serves as the connecting portion 32. The two mounting portions 33 are arranged in a left-right direction. Each mounting portion 33 has a longitudinally extending escape hole 34 extending from left to right.

[0048] A brush roller 40 is mounted inside the carrier 31, with its axis extending horizontally. Guide posts 42 are located coaxially with the brush roller 40 at each end. Each guide post 42 is positioned within the elongated clearance holes 34 of the mounting portion 33 on that side, allowing for forward and backward sliding relative to the elongated clearance holes 34. A connecting shaft 43 is fixedly mounted on the left guide post 42 (on the side closest to the lift base 21). The connecting shaft 43 is coaxially mounted with the guide post 42, and the end of the connecting shaft 43 facing away from the guide post 42 is rotatably engaged with the lift base 21.

[0049] The connecting shaft 43 passes through the through hole on the inner side of the transmission wheel 24, and a telescopic gear 44 is fixedly mounted on the connecting shaft 43 and arranged coaxially therewith. The telescopic gear 44 is provided with a plurality of telescopic teeth 45 (such as Figure 7 ), and the telescopic teeth 45 can slide radially along the telescopic gear 44. Each telescopic tooth 45 is mounted with a spring, the other end of which is connected to the telescopic gear 44. The spring helps the telescopic teeth 45 return to their original position. The telescopic gear 44 is located inside the perforation of the transmission wheel 24 and meshes with the teeth 26 inside the perforation of the transmission wheel 24. That is, the telescopic teeth 45 mesh with the teeth 26. Therefore, when the drive motor 22 drives the transmission wheel 24 to rotate, the transmission wheel 24 can drive the brush roller 40 to rotate via the telescopic gear 44.

[0050] When the sliding seat 30 drives the carrier 31 to slide back and forth, the brush roller 40 remains stationary, so relative movement occurs between the carrier 31 and the brush roller 40 , that is, the avoidance slot 34 can ensure the movement of the carrier 31 .

[0051] The side of the brush roller 40 facing the condenser 11 is set to be a plane, and the plane has multiple exhaust holes 41 (such as Figure 8As shown in the figure, multiple air holes 41 can increase the blowing area. The inside of the brush roller 40 is a hollow structure, and all the air holes 41 are connected to the inside of the brush roller 40. When the air holes 41 spray air toward the condenser 11, the dust inside the condenser 11 can be blown out. The outer peripheral wall of the brush roller 40, except for the outer side of the plane, is covered with bristles. The bristles on the brush roller 40 are in contact with the condenser 11. That is, the two brush rollers 40 are respectively located on the front and rear sides of the condenser 11, and can blow air and brush the front and rear sides of the condenser 11 respectively.

[0052] A vent pipe 47 is fixedly mounted on the right side surface of the guide column 42 on the right side of the brush roller 40, and the vent pipe 47 is connected to the air hole 41 on the brush roller 40. The support frame 31 is fixedly connected to the mounting portion 33 on the right side with a bracket 35, and an air inlet pipe 36 is fixedly mounted on the bracket 35. The air inlet pipe 36 is connected to an air supply source, which is an air pump. The vent pipe 47 is sealed and slidably fitted with the air inlet pipe 36. In the initial state, the vent pipe 47 is connected to the air inlet pipe 36, and the gas enters the brush roller 40 through the air inlet pipe 36 and the vent pipe 47, and is then blown out from the air hole 41. When the sliding seat 30 drives the support frame 31 to slide back and forth, the vent pipe 47 is separated from the air inlet pipe 36 (such as Figure 9 As shown), the gas cannot be blown out from the air holes 41, that is, when the brush rollers 40 on both sides rotate at the same time, only the air holes 41 on one side are blown, and the air blowing on the other side is temporarily stopped.

[0053] like Figure 10 As shown, the right mounting portion 33 is provided with a horizontally arranged accommodating cavity 37, the longitudinal direction of which is arranged in the front-to-back direction. The accommodating cavity 37 is connected to the avoidance long hole 34. A limit block 38 is horizontally slidably installed in the accommodating cavity 37, and a cylinder (not shown in the figure) is installed on the limit block 38 to drive the sliding movement. The cylinder and the limit block 38 are elastically slidably connected. A limit slot 46 is provided on the right guide post 42. The limit slot 46 matches the shape of the limit block 38. When the limit block 38 extends and abuts the guide post 42, as the guide post 42 rotates, when the limit slot 46 corresponds to the limit block 38, the limit block 38 is inserted into the limit slot 46, thereby limiting the rotation of the brush roller 40, and the telescopic teeth 45 will continuously slide along the radial direction of the telescopic gear 44.

[0054] It is particularly emphasized that the limit groove 46 and the air hole 41 are symmetrically arranged in the front-to-back direction, that is, when the limit groove 46 is located on the front side, the air hole 41 faces the rear side, so when the limit block 38 is inserted into the limit groove 46, the air hole 41 is just facing the condenser 11.

[0055] A pressure sensor 39 is fixedly installed at the bottom of the mounting portion 33 on the right side. When the mounting portion 33 descends and abuts against the pipe 12, the pressure sensor 39 just contacts the pipe 12. After the pressure sensor 39 detects the signal, the limit block 38 is extended and inserted into the limit groove 46 to limit the rotation of the brush roller 40. The air hole 41 continuously blows air toward the condenser 11.

[0056] Support frames 60 are provided on both sides of the condenser 11. The support frames 60 are fixedly mounted on the external machine casing 10, and each support frame 60 is provided with a through hole 61 that passes through the left and right sides. The left and right ends of the brush roller 40 are respectively inserted into the corresponding through holes 61, and the end of the brush roller 40 slides with the inner wall of the through hole 61 to support the brush roller 40 and enhance the stability of the brush roller 40.

[0057] In the initial state, the front and rear brush rollers 40 are both located near the top of the condenser 11. When the condenser 11 needs to be dusted, the brush rollers 40 rotate and the air holes 41 start blowing air. The lifting seat 21 drives the front and rear brush rollers 40 to descend simultaneously. When the pressure sensor 39 on one side of the support frame 31 abuts the horizontal section of the pipe 12, the lifting seat 21 temporarily stops descending. After the pressure sensor 39 on the side abutting the pipe 12 detects a signal, the limit block 38 extends and inserts into the limit groove 46, limiting the rotation of the brush rollers 40. The air holes 41 continue to blow air toward the condenser 11. That is, the air holes 41 on one side continuously blow air toward the condenser 11, blowing the dust toward the other side, while the brush roller 40 on the other side continuously rotates to clean the dust attached to the condenser 11 on that side. As the brush roller 40 on this side rotates, the air holes 41 on the brush roller 40 also blow air. However, the air holes 41 on this side are in a rotating state, and the blowing force is much smaller than that on the opposite side. This ensures that dust is blown to only one side, preventing dust from remaining in the middle of the condenser 11. After working for a certain period of time, the sliding seat 30 drives the supporting frame 31 to slide back and forth, and then the lifting seat 21 continues to drive the two brush rollers 40 to descend, so that the brush roller 40 on one side passes over the pipe 12 on that side, and then the sliding seat 30 drives the supporting frame 31 to return to its original position.

[0058] When the sliding seat 30 drives the supporting frame 31 to retreat away from the pipe 12, the vent pipe 47 is separated from the air inlet pipe 36, and the air hole 41 stops blowing air temporarily. At the same time, after the pressure sensor 39 is separated from the pipe 12, the limit block 38 is quickly retracted, and the brush roller 40 starts to rotate. The bristles on the brush roller 40 are always in contact with the condenser 11, which can clean it.

[0059] As the brush roller 40 continues to descend, the horizontal sections of the duct 12 are staggered front and back in the vertical direction. Similarly, the pressure sensor 39 on the other side of the support frame 31 abuts against the horizontal section of the duct 12 in an alternating manner. That is, the front and rear support frames 31 alternately abut against the horizontal section of the duct 12, always keeping the brush roller 40 on one side rotating and the brush roller 40 on the other side stationary, thereby cleaning dust from both the inside and outside of the condenser 11. Air is only blown to one side of the duct 12, effectively preventing dust from remaining on the duct 12 inside the condenser 11.

[0060] like Figure 11 As shown, the cleaning module includes comb teeth 50 , a combing frame 51 and cleaning teeth 53 .

[0061] A row of comb teeth 50 is provided on the bottom of the connecting portion 32 of the carrier 31. When the brush roller 40 rotates, the bristles on the brush roller 40 will continuously pass through the gaps between the comb teeth 50, thereby cleaning away debris on the bristles, and the debris will remain on the comb teeth 50.

[0062] A combing frame 51 is vertically slidably installed on the carrier frame 31. The combing frame 51 is a U-shaped structure, and the combing frame 51 has two side panels and a horizontal panel. The two opposite side panels of the combing frame 51 are vertically slidably matched with the left and right mounting parts 33 respectively. A row of cleaning teeth 53 is provided on the horizontal panel of the combing frame 51, and each cleaning tooth 53 corresponds to the gap between the comb teeth 50. When the combing frame 51 slides up and down, the cleaning teeth 53 can clean the debris on the comb teeth 50.

[0063] Guide grooves 52 are provided on both side panels of the combing frame 51, which are connected to each other from left to right. The guide grooves 52 are tilted, and the connecting shaft 43 on the left side of the brush roller 40 passes through the guide groove 52 on the left, and the ventilation pipe 47 on the right side of the brush roller 40 passes through the guide groove 52 on the right. Since the position of the brush roller 40 does not change, when the sliding seat 30 drives the carrier frame 31 to slide forward and backward, the inclined guide grooves 52 will force the combing frame 51 to slide vertically on the carrier frame 31 to complete the cleaning of the comb teeth 50.

[0064] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
