Description

Technical Field

[0001] The 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 tube to the air near the tube very quickly. The working process of the condenser is an exothermic process, so the condenser temperature is relatively high.

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

[0004] The air conditioner condenser is the core heat dissipation component of the air conditioner outdoor unit, and its efficient operation is directly related to the overall cooling performance. Since the equipment is exposed to the complex outdoor environment for a long time, 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 cause a sharp reduction in the effective heat dissipation area. The surface of the pipe that should have been fully exposed to the air for heat exchange is blocked by dust, and the heat loss efficiency is greatly reduced, making the air conditioning cooling effect 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 of the condenser or adhere to the pipes, which cannot be effectively removed, and the cleaning effect is not ideal. Summary of the invention

[0005] The present invention provides a dust removal device for the condenser of an outdoor unit of an air conditioner, aiming to solve the technical problem in the related art that since the device is long-term exposed to the complex outdoor environment, a large amount of dust and impurities are easily deposited on the inner side of the condenser. These attachments not only form a physical heat insulation layer, but also lead to a sharp reduction in the effective heat dissipation area. The surface of the pipeline that should originally be in full contact with air for heat exchange is blocked by dust, resulting in a significant reduction in the heat dissipation efficiency and a poor refrigeration effect of the air conditioner. In the above technical solution, when air flow is used to wash both sides of the condenser simultaneously, since there are many pipelines passing through the condenser, this method may cause impurities to stay in the middle position of the condenser or adhere to the pipelines, and cannot be effectively removed, resulting in an unsatisfactory cleaning effect.

[0006] A dust removal device for the condenser of an outdoor unit of an air conditioner according to the present invention includes: an outdoor unit housing and a condenser. There are pipelines provided on the condenser, and the horizontal sections of the pipelines are arranged staggered back and forth in the vertical direction. A dust removal module is provided inside the outdoor unit housing.

A limiting groove is provided on the guide column, and a limiting block is elastically slidably installed back and forth at a position corresponding to the limiting groove on the carrier frame. A detection member is provided at the bottom of the carrier frame. When the carrier frame descends and the detection member abuts against the horizontal section of the pipeline, the limiting block is inserted into the limiting groove to limit the rotation of the brush roller, and the air holes blow air towards the condenser.

[0007] Preferably, the driving unit includes a driving motor provided on the lifting seat. A driving wheel is fixedly installed at the output end of the driving motor. A transmission wheel is rotatably installed on the side surface of the lifting seat, and the axis of the transmission wheel is kept horizontal with that of the driving wheel. The transmission wheel and the driving wheel are connected by a transmission belt. A through hole penetrating left and right is provided inside the transmission wheel, and a plurality of teeth are provided along the circumferential direction on the inner side wall of the through hole. A connecting shaft is fixedly connected to one of the guide columns on the brush roller. The connecting shaft is coaxially arranged with the guide column, and the end of the connecting shaft away from the guide column is rotationally matched with the lifting seat. A telescopic gear is fixedly installed on the connecting shaft coaxially with it, and the telescopic gear meshes with the teeth on the inner side of the through hole of the transmission wheel.

[0008] The effect is that it can drive the brush roller to rotate, and when the limiting block is inserted into the limiting groove, it can limit the rotation of the brush roller.

[0009] Preferably, a comb tooth for cleaning the brush roller is provided on the carrier frame. A combing frame is slidably matched vertically on the carrier frame, and a cleaning tooth matched with the comb tooth is provided on the combing frame.

[0010] Its effects are as follows: The comb teeth can clean the bristles on the brush roller, and the up-and-down sliding of the combing frame can clean the debris on the comb teeth.

[0011] Preferably, the combing frame has a U-shaped structure and includes two side plates and a cross plate. Guide grooves that penetrate from left to right are formed on the side plates of the combing frame. The guide grooves are inclined, and the connecting shaft on the brush roller passes through the guide grooves. The connecting shaft is in blocking fit with the groove walls of the guide grooves.

[0012] Its effects are as follows: The forward and backward sliding of the carrier frame can force the combing frame to move up and down to clean the debris on the comb teeth.

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

[0014] Preferably, a receiving cavity communicating with the avoidance long hole is provided on the carrier frame. A limiting block is slidably fitted in the receiving cavity. A cylinder is provided in the receiving cavity, and the cylinder is elastically slidably connected to the limiting block.

[0015] Its effects are as follows: The cylinder can drive the limiting block to insert into the limiting groove on the guide post to restrict the rotation of the brush roller.

[0016] Preferably, the detection member is a pressure sensor.

[0017] Preferably, the inner side of the brush roller is a hollow structure, and the air holes communicate with the inside of the brush roller. A pump body is connected to the brush roller.

[0019] Preferably, support frames are provided on both the left and right sides of the condenser.

The left and right ends of the brush roller respectively penetrate into the corresponding through holes, and the ends of the brush roller are slidably fitted with the inner walls of the through holes.

[0020] With the above technical solution, the beneficial effects of the present invention are as follows: When dust removal of the condenser is required, the lifting seat drives the front and rear brush rollers to descend simultaneously. When the pressure sensor on one side of the bearing frame abuts against the horizontal section of the pipeline, the lifting seat temporarily stops descending. After the pressure sensor on the side abutting against the pipeline detects a signal, the limiting block extends out, and the limiting block is inserted into the limiting groove to restrict the rotation of the brush roller, and the air holes continuously blow air towards the condenser. As the brush roller continues to descend, since the horizontal sections of the pipeline are arranged staggered in the front and rear directions in the vertical direction, there is always one side of the air holes continuously blowing air towards 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 front and rear bearing frames alternately abut against the horizontal section of the pipeline, 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, preventing the dust from floating inside the outer machine housing and finally causing the dust to fall back on the condenser again. It can effectively clean the dust attached to the condenser and avoid the remaining dust on the pipeline inside the condenser. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0033] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0034] As Figures 1 to 11 shown, a specific embodiment of a dust removal device for an air conditioner outdoor unit condenser of the present invention includes an outer machine housing 10, a dust removal module, and a cleaning module.

[0035] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a condenser 11 is fixedly installed inside the outer machine housing 10. A pipeline 12 is installed on the condenser 11. The pipeline 12 has a serpentine structure, and all horizontal sections on the pipeline 12 penetrate the condenser 11 from left to right, and all horizontal sections are arranged staggered in the front and back directions in the vertical direction (as Figure 4 shown). That is, the part connecting the ends of adjacent two horizontal sections is inclined. The installation structure of the pipeline 12 on the condenser 11 belongs to the prior art and will not be elaborated here.

[0036] Other structures such as fan blades, compressors, and controllers are also provided on the outer machine housing 10. These structures all belong to the prior art and will not be elaborated either.

[0037] The dust removal module includes a lifting mechanism and a dust removal mechanism. As Figure 2 and Figure 5 shown, the lifting unit includes a lead screw 20 rotatably installed inside the outer machine housing 10. The lead screw 20 is vertically arranged and is located at a position close to the left side inside the outer machine housing 10. One end of the lead screw 20 is installed with a motor (not shown in the figure) for driving its rotation.

[0038] A lifting seat 21 is screwed onto the screw rod 20, and the screw rod 20 passes through the lifting seat 21 up and down. The lifting seat 21 is vertically slidably matched with the inner wall of the outer housing 10, so that when the screw rod 20 rotates, the lifting seat 21 can be driven to move up and down. It is particularly emphasized that the screw rod 20 and the lifting seat 21 are both located on the left side of the condenser 11.

[0039] 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 arranged on the front and back sides of the condenser 11 respectively.

[0040] 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 .

[0041] A driving motor 22 is fixedly mounted on the upper surface of the lifting seat 21, a driving wheel 23 is fixedly mounted on the output end of the driving motor 22, a transmission wheel 24 is rotatably mounted on the right side of the lifting seat 21, the transmission wheel 24 rotates along an axis extending in the left-right direction, and the axis of the transmission wheel 24 is kept horizontal with the axis of the driving wheel 23. The transmission wheel 24 and the driving wheel 23 are connected by a transmission belt 25, so that when the driving motor 22 drives the driving wheel 23 to rotate, the driving wheel 23 can drive the transmission wheel 24 to rotate.

[0042] It is particularly 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.

[0043] The inner side of the transmission wheel 24 has a through hole which passes through from left to right. The through hole is coaxially arranged with the transmission wheel 24 , and a plurality of teeth 26 are arranged on the inner side wall of the through hole along the circumference thereof.

[0044] 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 portion 32, a mounting portion 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.

[0045] The sliding seat 30 is horizontally slidably mounted on the lifting seat 21 in the front-rear direction. The sliding seats 30 in the two front-rear dust removal mechanisms are respectively slidably assembled on the front and rear sides of the lifting seat 21. A driving member (not shown in the figure) for driving the sliding seat 30 to slide back and forth is provided on the lifting seat 21, and the driving member is used to drive the sliding seat 30 to slide back and forth. The driving member can be a cylinder or a lead screw structure.

[0046] A carrier frame 31 is fixedly mounted on the sliding seat 30. The carrier frame 31 is of a U-shaped structure, and the carrier frame 31 has a connecting portion 32 and two mounting portions 33. The opposite side panels of the carrier frame 31 are the mounting portions 33, and the bottom plate of the carrier frame 31 is the connecting portion 32, and the two mounting portions 33 are distributed in the left-right direction. Avoidance long holes 34 penetrating left and right are provided on both of the two mounting portions 33, and the length direction of the avoidance long holes 34 extends in the front-rear direction.

[0047] A brush roller 40 is provided inside the carrier frame 31, and the axis of the brush roller 40 extends in the left-right direction. Guide columns 42 are provided at both the left and right ends of the brush roller 40. The guide columns 42 are coaxially arranged with the brush roller 40, and the left and right guide columns 42 are respectively located in the avoidance long holes 34 of the mounting portions 33 on this side, and the guide columns 42 can slide back and forth relative to the avoidance long holes 34. A connecting shaft 43 is fixedly mounted on the left guide column 42 (the side close to the lifting seat 21). The connecting shaft 43 is coaxially arranged with the guide column 42, and the end of the connecting shaft 43 away from the guide column 42 is rotatably matched with the lifting seat 21.

[0048] The connecting shaft 43 passes through the through hole inside the transmission wheel 24, and a telescopic gear 44 coaxially arranged with it is fixedly mounted on the connecting shaft 43. A plurality of telescopic teeth 45 are provided along the circumferential direction of the telescopic gear 44 (such as Figure 7 ), and the telescopic teeth 45 can slide in the radial direction of the telescopic gear 44, and springs are installed on the telescopic teeth 45, and the other ends of the springs are connected to the telescopic gear 44, and the springs can help the telescopic teeth 45 to reset. The telescopic gear 44 is located inside the through hole of the transmission wheel 24, and the telescopic gear 44 meshes with the teeth 26 inside the through hole of the transmission wheel 24, that is, the telescopic teeth 45 and the teeth 26 are meshed with each other. Thus, when the driving motor 22 drives the transmission wheel 24 to rotate, the transmission wheel 24 can drive the brush roller 40 to rotate through the telescopic gear 44.

[0049] When the sliding seat 30 drives the carrier frame 31 to slide back and forth, the brush roller 40 remains stationary, so relative movement will occur between the carrier frame 31 and the brush roller 40, that is, the avoidance long holes 34 can ensure the movement of the carrier frame 31.

[0050] The side of the brush roller 40 facing the condenser 11 is set as a plane, and a plurality of rows of air holes 41 are provided on this plane (such as Figure 8As shown, the multiple exhaust holes 41 can increase the area of the blowing air. The inner side of the brush roller 40 is a hollow structure, and all the air holes 41 are communicated with the inside of the brush roller 40. When the air holes 41 jet air towards the condenser 11, the dust inside the condenser 11 can be blown out. The outer peripheral walls of the brush roller 40 except for this plane are all 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 back sides of the condenser 11, and can respectively blow air and brush the front and back sides of the condenser 11.

[0051] A trachea 47 is fixedly installed on the right side surface of the guide post 42 on the right side of the brush roller 40, and the trachea 47 is communicated with the air holes 41 on the brush roller 40. A support 35 is fixedly connected to the mounting part 33 on the right side of the carrier 31. An air inlet pipe 36 is fixedly installed on the support 35. An air supply source is communicated with the air inlet pipe 36, and the air supply source is an air pump. The trachea 47 and the air inlet pipe 36 are in sealed sliding fit. In the initial state, the trachea 47 is communicated with the air inlet pipe 36, and the gas enters the brush roller 40 through the air inlet pipe 36 and the trachea 47, and then is blown out from the air holes 41. When the sliding seat 30 drives the carrier 31 to slide back and forth, the trachea 47 is separated from the air inlet pipe 36 (as Figure 9 shown), and the gas cannot be blown out from the air holes 41. That is, when the two brush rollers 40 rotate simultaneously, only the air holes 41 on one side blow air, and the air blowing on the other side is temporarily stopped.

[0052] As Figure 10 shown, a horizontally arranged accommodation cavity 37 is provided on the mounting part 33 on the right side. The length direction of the accommodation cavity 37 is arranged along the front-back direction. The accommodation cavity 37 is communicated with the avoidance long hole 34. A limiting block 38 is horizontally slidably installed in the accommodation cavity 37, and a cylinder (not shown in the figure) for driving its sliding is installed on the limiting block 38, and the cylinder and the limiting block 38 are elastically slidably connected. A limiting groove 46 is opened on the guide post 42 on the right side. The shape of the limiting groove 46 matches that of the limiting block 38. When the limiting block 38 extends out and abuts against the guide post 42, as the guide post 42 rotates, when the limiting groove 46 corresponds to the limiting block 38, the limiting block 38 is inserted into the limiting groove 46 to limit the rotation of the brush roller 40, and the telescopic tooth 45 will continuously slide along the radial direction of the telescopic tooth gear 44.

[0053] It should be particularly emphasized that the limiting groove 46 and the air holes 41 are symmetrically arranged in the front-back direction. That is, when the limiting groove 46 is on the front side, the air holes 41 face the back side. Therefore, when the limiting block 38 is inserted into the limiting groove 46, the air holes 41 just face the condenser 11.

[0054] A pressure sensor 39 is fixedly installed at the bottom of the installation part 33 on the right side. When the installation part 33 descends and abuts against the pipeline 12, the pressure sensor 39 just contacts the pipeline 12. After the pressure sensor 39 detects a signal, the limit block 38 extends out, and the limit block 38 is inserted into the limit groove 46 to restrict the rotation of the brush roller 40, and the air holes 41 continuously blow air towards the condenser 11.

[0055] Support frames 60 are arranged on both the left and right sides of the condenser 11. The support frames 60 are fixedly installed on the outer machine housing 10, and each support frame 60 is provided with a through hole 61 that penetrates from left to right. 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 is in sliding fit with the inner wall of the through hole 61, which plays a supporting role for the brush roller 40 and enhances the stability of the brush roller 40.

[0056] In the initial state, the front and rear brush rollers 40 are both located at the upper position close to the condenser 11. When dust removal of the condenser 11 is required, the brush roller 40 rotates and the air holes 41 start to blow air at the same time. 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 carrier 31 abuts against the horizontal section of the pipeline 12, the lifting seat 21 temporarily stops descending. After the pressure sensor 39 on the side abutting against the pipeline 12 detects a signal, the limit block 38 extends out, and the limit block 38 is inserted into the limit groove 46 to restrict the rotation of the brush roller 40, and the air holes 41 continuously blow air towards the condenser 11. That is, the air holes 41 on one side continuously blow air towards the condenser 11 to blow the dust to 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. While the brush roller 40 on this side rotates, the air holes 41 on the brush roller 40 also blow air, but the air holes 41 on this side are in a rotating state, and the blowing force is much smaller than that of the opposite side, which can ensure that the dust can only be blown to one side and prevent the dust from remaining in the middle part of the condenser 11. After working for a certain period of time, the sliding seat 30 drives the carrier 31 to slide back and forth, and then the lifting seat 21 continues to drive the two brush rollers 40 to descend, so that one of the brush rollers 40 crosses the pipeline 12 on that side, and then the sliding seat 30 drives the carrier 31 to reset again.

[0057] When the sliding seat 30 drives the carrier 31 to retreat away from the pipeline 12, the ventilation pipe 47 is separated from the air inlet pipe 36, and the air holes 41 do not blow air temporarily. At the same time, after the pressure sensor 39 is separated from the pipeline 12, the limit block 38 quickly retracts, and the brush roller 40 starts to rotate. The bristles on the brush roller 40 always contact the condenser 11 and can clean it.

[0058] As the brush roller 40 continues to descend, since the horizontal sections of the pipeline 12 are arranged staggeredly back and forth in the vertical direction, similarly, the pressure sensor 39 on the bearing frame 31 on the other side abuts against the horizontal section of the pipeline 12, and this alternates in this way. That is to say, the bearing frames 31 on the front and back sides alternately abut against the horizontal section of the pipeline 12, always keeping one brush roller 40 rotating and the other brush roller 40 stationary, cleaning the dust inside and outside the condenser 11, and only using the method of blowing air to one side for the pipeline 12, effectively avoiding the remaining dust on the pipeline 12 inside the condenser 11.

[0059] As Figure 11 shown, the cleaning module includes a comb 50, a combing frame 51 and cleaning teeth 53.

[0060] A row of combs 50 is arranged at the bottom of the connecting part 32 of the bearing frame 31. When the brush roller 40 rotates, the bristles on the brush roller 40 will continuously pass through the gaps between the combs 50, so that the sundries on the bristles can be cleaned, and the sundries will remain on the combs 50.

[0061] A combing frame 51 is vertically slidably mounted on the bearing frame 31. The combing frame 51 has a U-shaped structure and has two side plates and a cross plate. The two opposite side plates of the combing frame 51 are respectively in vertical sliding fit with the left and right mounting parts 33. A row of cleaning teeth 53 is arranged on the cross plate of the combing frame 51, and each cleaning tooth 53 corresponds to the gap between the combs 50. When the combing frame 51 slides up and down, the cleaning teeth 53 can clean the sundries on the combs 50.

[0062] Guide grooves 52 that penetrate left and right are formed on both side plates of the combing frame 51. The guide grooves 52 are inclined, and the connecting shaft 43 on the left side of the brush roller 40 passes through the guide groove 52 on the left side, and the air pipe 47 on the right side of the brush roller 40 passes through the guide groove 52 on the right side. Since the position of the brush roller 40 will not change, when the sliding seat 30 drives the bearing frame 31 to slide back and forth, the inclined guide grooves 52 will force the combing frame 51 to slide vertically on the bearing frame 31 to complete the cleaning of the combs 50.

[0063] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
