Description

Technical Field

[0001] This invention relates to the field of air conditioning energy-saving technology, and in particular to an energy-saving device for household air conditioners. Background Technology

[0002] In an air conditioning system, during cooling mode, the heat exchanger in the outdoor unit acts as the condenser, while the heat exchanger in the indoor unit acts as the evaporator. In cooling mode, when the outdoor ambient temperature is too high, the temperature difference between the condenser and the outdoor environment decreases, leading to a reduction in the condenser's heat exchange efficiency. Consequently, the cooling capacity of the air conditioning system decreases. In other words, under high-temperature cooling conditions, the air conditioning system's cooling capacity will be reduced.

[0003] Currently, the cooling capacity of air conditioning systems is typically increased by increasing the airflow of the outdoor unit's fan or raising the compressor frequency. However, this significantly increases the power consumption of the air conditioning system, severely reducing its overall energy efficiency. To avoid wasting a large amount of electricity under these conditions, energy-saving measures can be installed inside the outdoor unit. Several factors contribute to reduced compressor efficiency, including excessive dust on the air conditioner's filter, which hinders proper airflow and heat dissipation, leading to a substantial increase in power consumption and a severe decrease in overall energy efficiency. Therefore, this application proposes an energy-saving device for household air conditioners. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned technical problems by proposing an energy-saving device for household air conditioners.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A household air conditioner energy-saving device includes an air conditioner main unit. An air inlet filter is provided on the side of the air conditioner main unit. A cleaning mechanism for cleaning the air inlet filter is provided on the air conditioner main unit. The cleaning mechanism includes a mounting plate that can move up and down. Two mounting blocks are fixed on the mounting plate, arranged vertically. A rectangular block is slidably connected to the mounting block. A cleaning brush for cleaning the air inlet filter is fixed on the rectangular block. A connecting block is fixed on the rectangular block. A spring is fixed on the connecting block and fixedly connected to the mounting block. A magnet is fixed on the connecting block. A first electromagnet and a second electromagnet, respectively opposite to the two magnets, are mounted on the mounting plate. A hollow plate opposite to the air inlet filter is mounted on the mounting plate. A negative pressure hole is provided through the hollow plate. The cleaning mechanism also includes a fan. The fan is connected to the hollow plate, and negative pressure is generated at the negative pressure hole when the fan is working.

[0007] Preferably, the air conditioner unit is equipped with two rectangular frames, each of which has a slider slidably connected to it and a screw rotatably connected to it. A first motor is installed at the upper end of one of the rectangular frames, and the output end of the first motor is fixedly connected to the screw. The screw passes through the slider and is threadedly connected to it. The mounting plate is fixed on the two sliders.

[0008] Preferably, a short shaft is fixed to the bottom of each of the two screws, the short shaft passes through the rectangular frame and is rotatably connected to it, a transmission wheel is fixed on each of the two short shafts, and the two transmission wheels are connected by a transmission belt.

[0009] Preferably, the first electromagnet and the second electromagnet are controlled by separate switches, and the magnetic poles of the first electromagnet and the second electromagnet are the same on the opposite side of the magnetic block.

[0010] Preferably, a dust collection box is installed on one of the sliders, the opening of the dust collection box is arranged downwards, the fan is installed on the dust collection box and the air inlet of the fan is connected to the dust collection box, the dust collection box is connected to the hollow plate through a short pipe, and a dust filter is installed inside the dust collection box.

[0011] Preferably, a baffle is hinged to the bottom of the dust collection box, and the hinge of the baffle is located away from the fan.

[0012] Preferably, a second motor is installed on the dust collection box, a drive shaft is fixed to the output end of the second motor, a circular plate is fixed on the drive shaft, a connecting rod is eccentrically hinged to the circular plate, a transmission rod is hinged to the connecting rod, a connecting shaft is rotatably connected to the transmission rod, and the connecting shaft is fixedly connected to the side wall of the baffle.

[0013] Preferably, the dust filter is located between the short pipe and the fan, and the dust filter is made of stainless steel. The dust filter is installed in the dust collection box by bolts.

[0014] Preferably, a mounting post is fixed on the mounting plate, and a bearing block is fixed on the mounting post, with the first electromagnet and the second electromagnet mounted on the bearing block.

[0015] Compared with the prior art, the beneficial effects of this invention are as follows:

[0016] 1. Effective cleaning of the air intake filter: By setting up a cleaning mechanism, the cleaning brush moves up and down to clean the air intake filter, which can effectively remove dust, pollen and other fine particles from the filter, ensuring normal air intake and heat dissipation of the filter, and avoiding the problem of increased power consumption and reduced energy efficiency of the air conditioning system due to filter blockage.

[0017] 2. The cleaning process is highly efficient and causes minimal damage to the filter: The bristles of the cleaning brush are made of nylon, which is soft and elastic. It can effectively clean the dust on the air intake filter without damaging the filter, thus extending the filter's service life.

[0018] 3. Excellent dust collection effect: The cleaning mechanism is equipped with a fan and a hollow plate. When the fan is working, negative pressure is generated at the negative pressure holes on the hollow plate, which can promptly suck the dust swept off by the cleaning brush into the hollow plate, and then enter the dust collection box through the short pipe, where it is intercepted by the dust filter, effectively preventing the accumulation of dust in the air conditioning unit.

[0019] 4. Easy dust filter cleaning: By setting up components such as a second motor, drive shaft, circular plate, connecting rod, transmission rod, connecting shaft, and baffle, when it is necessary to clean the dust filter, the baffle can be controlled to move down to form an opening, and the fan can be reversed to blow the dust filter clean. The blown dust falls onto the baffle and then falls down. The dust is collected by a dust collection box at the bottom of the dust collection box. The dust collection box can be cleaned regularly. The operation is simple and convenient.

[0020] In summary, this invention, by setting up a cleaning mechanism and using a vertically movable cleaning brush to clean the air intake filter, effectively avoids excessive dust affecting the working efficiency of the air conditioner compressor, reduces power consumption, and improves the overall energy efficiency. At the same time, the negative pressure generated by the fan removes the dust swept off by the cleaning brush and can also back-blow clean the dust filter, ensuring the dust collection effect and the service life of the dust filter. The overall design is reasonable, the operation is convenient, and the energy-saving effect is significant. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Reference Figures 1-5 An energy-saving device for household air conditioners includes an air conditioning unit 1. An air inlet filter 2 is located on the side of the air conditioning unit 1. The air inlet filter 2 is made of high-density nylon and has an anti-static treatment on its surface, effectively intercepting fine particulate matter such as dust and pollen in the air. The air conditioning unit 1 is equipped with a cleaning mechanism for cleaning the air inlet filter 2. The cleaning mechanism includes a vertically movable mounting plate 14 made of high-strength aluminum alloy with an anodized surface, providing excellent corrosion resistance and wear resistance. Its dimensions are customized according to the actual dimensions of the air conditioning unit 1 to ensure complete coverage of the cleaning area of ​​the air inlet filter 2.

[0029] Two rectangular frames 3 are bolted to the air conditioner unit 1. Each rectangular frame 3 has a slider 6 slidably connected within it. The slider 6 is made of engineering plastic and has a copper slide rail embedded inside to reduce friction with the inner wall of the rectangular frame 3 and improve sliding smoothness. Each rectangular frame 3 is rotatably connected to a screw 5 via bearings. The screw 5 is made of stainless steel with a chrome-plated surface to improve wear resistance and corrosion resistance.

[0030] One of the rectangular frames 3 has a first motor 4 bolted to its upper end. The first motor 4 is a low-noise, high-torque DC motor, and its output end is fixedly connected to the screw 5 via a coupling to ensure the stability and reliability of power transmission. The screw 5 passes through the slider 6 and is threaded to it. The mounting plate 14 is fixed to the two sliders 6 by welding to ensure a firm connection.

[0031] Both screws 5 have a short shaft 11 fixed to their bottoms. The short shaft 11 is welded to the screw 5 to ensure connection strength. The short shaft 11 passes through the rectangular frame 3 and is rotatably connected to it via bearings. A transmission wheel 13 is fixed to each of the two short shafts 11. The transmission wheel 13 is made of rubber with anti-slip texture to improve transmission efficiency. The two transmission wheels 13 are connected by a synchronous belt 12, which has advantages such as high transmission accuracy and low noise.

[0032] Two mounting blocks 17, arranged vertically, are bolted to the mounting plate 14. A rectangular block 18, made of stainless steel and polished to reduce sliding resistance, is slidably connected to each mounting block 17. A cleaning brush 9, for cleaning the air intake filter 2, is bolted to the rectangular block 18. The brush bristles are made of nylon, are soft and elastic, effectively cleaning dust from the air intake filter 2 without damaging it.

[0033] A connecting block 20 is bolted to the rectangular block 18, and a spring 19 is bolted to the connecting block 20. The spring 19 is a high-strength compression spring, and its elastic coefficient is selected according to the actual cleaning requirements. The spring 19 is welded to the mounting block 17 to ensure a firm connection. A magnet 21 is bolted to the connecting block 20. The magnet 21 is a neodymium iron boron strong magnet with strong magnetic force, which can generate sufficient repulsion with the electromagnet.

[0034] A first electromagnet 16 and a second electromagnet 31, respectively, opposite to the two magnetic blocks 21, are bolted onto the mounting plate 14. A mounting post 15 is welded to the mounting plate 14, and a support block 10 is bolted to the mounting post 15. The first electromagnet 16 and the second electromagnet 31 are bolted onto the support block 10. The first electromagnet 16 and the second electromagnet 31 are controlled by separate switches. The switches are waterproof and dustproof and are installed in an easily accessible location on the air conditioning unit 1. The magnetic poles of the first electromagnet 16 and the second electromagnet 31 are the same on the opposite sides of the magnetic blocks 21, ensuring that a repulsive force is generated when energized.

[0035] When the mounting plate 14 moves upward, the switch controlling the first electromagnet 16 is pressed, the first electromagnet 16 is energized, and the repulsive force between the first electromagnet 16 and the magnetic block 21 is greater than the elastic force of the spring 19, thereby driving the mounting block 17, the rectangular block 18 and the cleaning brush 9 to move. That is, the upper cleaning brush 9 abuts against the air inlet filter 2, which can clean the air inlet filter 2. Then, the negative pressure hole 8 on the hollow plate 7 that follows generates negative pressure, which can suck away the swept dust.

[0036] When the mounting plate 14 moves downward, the switch controlling the second electromagnet 31 is pressed, the second electromagnet 31 is energized, and the repulsive force between the second electromagnet 31 and the magnetic block 21 is greater than the elastic force of the spring 19, thereby driving the mounting block 17, the rectangular block 18 and the cleaning brush 9 to move. That is, the cleaning brush 9 on the lower side abuts against the air inlet filter 2, which can clean the air inlet filter 2. Then, the negative pressure hole 8 on the hollow plate 7 that follows generates negative pressure, which can suck away the swept dust.

[0037] A hollow plate 7, opposite the air inlet filter 2, is bolted to the mounting plate 14. The hollow plate 7 is made of aluminum alloy and is internally sealed to ensure a negative pressure effect. A negative pressure hole 8 is provided through the hollow plate 7. The cleaning mechanism also includes a fan 23, which is a centrifugal fan with a large air volume and low noise. The fan 23 is connected to the hollow plate 7 through a pipe, and negative pressure is generated at the negative pressure hole 8 when the fan 23 is working.

[0038] A dust collection box 22 is bolted to one of the sliders 6, with the opening of the dust collection box 22 facing downwards. A fan 23 is bolted to the dust collection box 22, and the air inlet of the fan 23 is connected to the dust collection box 22. The dust collection box 22 is connected to the hollow plate 7 via a short pipe. The short pipe is a flexible rubber hose, which is easy to install and adjust. A dust filter 30 is bolted inside the dust collection box 22, located between the short pipe and the fan 23. The dust filter 30 is made of stainless steel, which is corrosion-resistant and easy to clean. The dust filter 30 is bolted inside the dust collection box 22 for easy disassembly and replacement. A baffle 29 is hinged to the bottom of the dust collection box 22. The hinge of the baffle 29 is located away from the fan 23. The baffle 29 is made of aluminum alloy with a powder-coated surface, which has good corrosion resistance.

[0039] A second motor 24 is bolted to the dust collection box 22. The second motor 24 is a small DC motor with advantages such as adjustable speed and convenient control. The output end of the second motor 24 is fixed to a drive shaft 25 via a coupling. A circular plate 26 is fixed to the drive shaft 25 via a key connection. A connecting rod 32 is eccentrically hinged to the circular plate 26. The connecting rod 32 is made of stainless steel, which is high in strength and wear-resistant. A transmission rod 27 is hinged to the connecting rod 32. A connecting shaft 28 is rotatably connected to the transmission rod 27 via a bearing. The connecting shaft 28 is fixedly welded to the side wall of the baffle 29. When it is necessary to clean the dust filter 30, the switch controlling the second motor 24 is pressed. The second motor 24 drives the drive shaft 25 and the circular plate 26 to rotate. Under the transmission of the connecting rod 32 and the transmission rod 27, the connecting shaft 28 is moved. The movement of the connecting shaft 28 causes the baffle 29 to move downward. At this time, the opening formed by the baffle 29 and the dust collection box 22 is positioned away from the air inlet filter 2.

[0040] When the fan 23 reverses, it can blow air onto the dust filter 30, thus achieving back-blowing cleaning of the dust filter 30. The blown-off dust falls onto the baffle 29 and then falls down. The dust can be collected by setting a dust collection box at the bottom of the dust collection box 22. Regularly cleaning the dust collection box can achieve the cleaning of the dust filter 30.

[0041] When the household air conditioner's energy-saving device needs to clean the air intake filter 2, the entire cleaning mechanism will operate in an orderly manner according to the following steps:

[0042] Upward cleaning process:

[0043] The user operates the waterproof and dustproof switch installed in an easily accessible location on the air conditioner unit 1, pressing the switch controlling the first electromagnet 16 to energize it. At this time, the magnetic poles of the first electromagnet 16 and the magnetic block 21 are the same on opposite sides. According to the principle of repulsion between like poles, a repulsive force is generated between the first electromagnet 16 and the magnetic block 21. Since this repulsive force is greater than the elastic force of the spring 19, under the action of the repulsive force, the connecting block 20 will drive the rectangular block 18 to slide along the mounting block 17, thereby causing the upper cleaning brush 9 fixed on the rectangular block 18 to move towards the air inlet filter 2 until the upper cleaning brush 9 abuts against the air inlet filter 2.

[0044] Downward cleaning process:

[0045] If it is necessary to clean the air inlet filter 2 downwards, the user operates the switch of the second electromagnet 31 to energize it. Based on the principle of magnetic repulsion, the second electromagnet 31 and the magnetic block 21 generate a repulsive force, which is greater than the elastic force of the spring 19. Driven by this repulsive force, the connecting block 20 causes the rectangular block 18 to slide, moving the lower cleaning brush 9 towards the air inlet filter 2 until the lower cleaning brush 9 comes into contact with the air inlet filter 2.

[0046] The first motor 4 is started. The first motor 4 is a low-noise, high-torque DC motor. Its output end is fixedly connected to the screw 5 through a coupling to ensure stable power transmission. The first motor 4 drives one of the screws 5 to rotate. Since the bottom of the two screws 5 is connected to the transmission wheel 13 through the short shaft 11, and the two transmission wheels 13 are connected by the transmission belt 12, the two screws 5 will rotate synchronously.

[0047] The screw 5 passes through the slider 6 and is threadedly connected to it. As the screw 5 rotates, the slider 6 slides up and down along the rectangular frame 3. Because the mounting plate 14 is fixed to the two sliders 6 by welding, the mounting plate 14 moves up and down as the sliders 6 move.

[0048] When the mounting plate 14 moves upward, the upper cleaning brush 9 comes into contact with the air intake filter 2. As the mounting plate 14 moves, the upper cleaning brush 9 will brush the surface of the air intake filter 2, sweeping off the dust, pollen and other tiny particles attached to the air intake filter 2.

[0049] When the mounting plate 14 moves downward, the lower cleaning brush 9 comes into contact with the air inlet filter 2. Similarly, during the movement of the mounting plate 14, the lower cleaning brush 9 brushes and cleans the air inlet filter 2.

[0050] The blower 23 in the cleaning mechanism is a centrifugal blower, which features large air volume and low noise. The blower 23 is connected to the hollow plate 7 through a pipe. When the blower 23 starts working, it will generate negative pressure at the negative pressure hole 8 on the hollow plate 7.

[0051] During the cleaning process of brush 9 brushing the air inlet filter 2, the dust swept off will be sucked into the hollow plate 7 through the negative pressure hole 8 under the action of negative pressure, and then enter the dust collection box 22 through the short pipe.

[0052] The dust collection box 22 is equipped with a stainless steel dust filter 30, which is located between the short pipe and the fan 23. Dust will be intercepted by the dust filter 30, while the filtered air will be discharged through the fan 23, thereby achieving effective removal of swept dust.

[0053] When the dust filter 30 needs to be cleaned, the user presses the switch to control the second motor 24. The second motor 24 is a small DC motor with advantages such as adjustable speed and convenient control. After the second motor 24 is started, its output end drives the drive shaft 25 to rotate through the coupling. A circular plate 26 is fixed on the drive shaft 25 by a key connection, and the circular plate 26 rotates accordingly.

[0054] A connecting rod 32 is eccentrically hinged to the circular plate 26, and the connecting rod 32 is hinged to the transmission rod 27. A connecting shaft 28 is rotatably connected to the transmission rod 27 via a bearing, and the connecting shaft 28 is fixedly welded to the side wall of the baffle 29. During the rotation of the circular plate 26, the connecting rod 32 and the transmission rod 27 drive the connecting shaft 28 to move, thereby causing the baffle 29 to move downward around the hinge. At this time, the opening formed by the baffle 29 and the dust collection box 22 is positioned away from the air inlet filter 2.

[0055] When the fan 23 is turned on and reversed, it blows air onto the dust filter 30 to clean it. The reverse airflow blows off the dust trapped on the dust filter 30, and the blown-off dust falls onto the baffle 29 and then falls down along the baffle 29.

[0056] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
