Description

Technical Field

[0001] The present invention belongs to the technical field of air-conditioning energy saving, and in particular relates to an automatic cleaning and energy-saving device for terminal air-conditioning equipment. Background Art

[0002] Central air conditioning is a device that controls different rooms by connecting multiple terminal devices through air ducts or refrigerant pipes to achieve the purpose of indoor air conditioning. It uses duct air supply, so one host can control multiple different rooms and introduce fresh air to prevent the occurrence of air-conditioning disease. Specifically, the indoor unit is installed with a pipe for transporting refrigerant. The indoor unit is also equipped with a water pump for transporting cooling water and a fan for exhausting air. When cooling, the fan draws indoor air into the indoor unit and contacts the pipe for transporting refrigerant. In this process, the pipe absorbs heat from the air, causing the water vapor in the air to liquefy. The liquefied liquid water is then pumped out to the outside through the pipe by the water pump.

[0003] When using central air conditioning, it monitors the indoor temperature in real time and automatically starts the air conditioner when the indoor temperature does not reach the preset value. During the cooling process, the indoor unit draws indoor air. The air needs to pass through the filter component to filter out dust and other impurities inside to prevent dust and other impurities in the air from entering the indoor unit and affecting the use. However, after a period of use, the filter component is gradually clogged with dust, which reduces the air content entering the indoor unit per unit time, thereby reducing the heat exchange rate between the indoor air and the indoor unit. As a result, the indoor cooling rate is reduced, and the air conditioner needs to be turned on for a longer time to reduce the indoor temperature to the preset value. During this process, the fan and water pump of the indoor unit need to be continuously turned on, thereby consuming more electricity.

DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0037] like Figures 1 to 5As shown, an automatic cleaning and energy-saving device for terminal air-conditioning equipment according to an embodiment of the present invention includes a temperature sensor, a system controller, a heat dissipation component, and a casing 1. An air outlet 11 is installed on the side of the casing 1. A water outlet pipe 12 is connected and fixedly connected to the side of the casing 1 opposite to the air outlet 11. The bottom end of the casing 1 is connected and fixedly connected to a receiving frame 2. A return air outlet is installed on the bottom surface of the receiving frame 2. The return air outlet belongs to the prior art and is not shown in this application.

[0038] A filter 21 is fixedly connected to the interior of the receiving frame 2. A pair of cleaning covers 24 are symmetrically provided at the upper and lower ends of the filter 21. A dispersion head 241 is installed inside the cleaning cover 24. A rectangular nut 23 is fixedly connected to the side of the cleaning cover 24 away from the filter 21. A screw 22 is meshed and inserted into the interior of the rectangular nut 23. The ends of the screw 22 extend to the outside of the receiving frame 2. A pair of motors 25 are fixedly connected to the ends of the receiving frame 2. The output ends of the motors 25 are fixedly connected to the ends of the screw 22.

[0039] A water injection hose 26 is connected and fixed to the surface of the cleaning cover 24. A pair of pump bodies 27 are fixed to the end of the receiving frame 2 away from the motor 25. One side of the pump body 27 is provided with a water tank 3 fixed to the side of the receiving frame 2. A buffer assembly is connected between the pump body 27 and the water tank 3.

[0040] After the air conditioner indoor unit has been used for a period of time, the degree of clogging of the filter component by dust gradually increases, which reduces the air content entering the indoor unit per unit time, thereby reducing the heat exchange rate between the indoor air and the indoor unit. As a result, the indoor cooling rate is reduced, and the air conditioner needs to be turned on for a longer time to reduce the indoor temperature to a predetermined value. During this process, the fan and water pump of the indoor unit need to be continuously turned on, thereby consuming more electricity. Therefore, it is necessary to optimize the structure of the air conditioner indoor unit based on the above needs; to solve the above problems, the embodiment of the present invention is provided with a cleaning cover 24, a dispersion head 241 and other structures to realize automatic cleaning of the filter 21. The specific use process is as follows: when the air conditioner is in use, the fan in the indoor unit casing 1 draws indoor air in through the return air inlet. During the drawing process, dust and other impurities in the air will be filtered through the filter 21. Then, the air contacts the pipe for transporting the refrigerant in the casing 1. The pipe absorbs heat in the air, causing the water vapor in the air to liquefy. Then, the liquefied liquid water is pumped out to the outside through the pipe by the water pump; the embodiment of the present invention is not shown in the drawings of the specification;

[0041] In the embodiment of the present invention, the electric control structures such as the motor 25 and the pump body 27 are all controlled by a microcomputer. After the air conditioner has been used for a period of time, the motor 25 and the pump body 27 are started, and the motor 25 drives the screw 22 to rotate. When the screw 22 rotates, a meshing transmission is generated between the screw 22 and the rectangular nut 23. The rectangular nut 23 is fixedly connected to the cleaning cover 24. The boundary of the filter 21 is fixedly connected with a frame, and the cleaning cover 24 is embedded in the frame. As the screw 22 rotates, the rectangular nut 23 drives the cleaning cover 24 to move horizontally, and the frame limits the position of the cleaning cover 24. At the same time, the pump body 27 is started, and the liquid water inside the water tank 3 is drawn in through the buffer component, and then injected into the cleaning cover 24 through the water injection hose 26, and then sprayed onto the surface of the filter 21 through the dispersion head 241. The dispersion head 241 is a block structure with multiple holes on the surface. When the liquid water passes through the dispersion head 241, the dispersion head 241 can The liquid water is atomized and dispersed so that the liquid water is evenly sprayed onto the surface of the filter 21. It should be noted that the upper cleaning cover 24 sprays liquid water and the lower cleaning cover 24 draws liquid water. Therefore, after the liquid water passes through the filter 21, it will be drawn into the lower cleaning cover 24. As the cleaning cover 24 moves, the entire filter 21 is cleaned, and the dust blocked on the surface of the filter 21 is cleaned and falls off. Thereafter, the cleaning cover 24 is controlled to reset, and the motor 25 and the pump body 27 are turned off to realize automatic cleaning of the filter 21. The structure of the indoor unit is optimized, and liquid water is prevented from falling during cleaning to avoid affecting the cleanliness of the room. After the filter 21 is cleaned, the air entering the indoor unit per unit time is normal, so the indoor cooling speed is normal, the air conditioner does not need to be turned on for a longer time to reduce the indoor temperature to the predetermined value, and the fan and water pump of the indoor unit do not need to be turned on continuously, thereby saving electricity.

[0042] It should be noted that the temperature sensor described in the embodiment of the present invention is installed on the outside of the water pump to monitor the working temperature of the water pump. When the temperature sensor detects that the temperature of the water pump is too high, it will feed back a signal to the system controller, and then the system controller will send an operating instruction to the heat dissipation component to make the heat dissipation component run to dissipate heat for the water pump. At the same time, it also sends an operating instruction to the motor 25 and the pump body 27 to clean the filter 21, thereby solving the problem of excessive temperature of the water pump from the root, thereby achieving the effect of energy saving for the water pump. It should be noted that the heat dissipation component is a prior art, and it can be implemented in many ways, such as using a fan to dissipate heat or using water flow to dissipate heat, that is, air cooling or water cooling in the usual sense, which will not be described in detail in the embodiment of the present invention.

[0043] like Figures 4 to 7As shown, the side of the water injection hose 26 is linearly and evenly fixed with multiple magnetic iron sheets; multiple magnetic blocks 20 are fixed to the side of the receiving frame 2 close to the water injection hose 26, and the magnetic block 20 continuously has an attractive force with the magnetic iron sheet; when the cleaning cover 24 moves, the water injection hose 26 connected to the cleaning cover 24 will become loose, and the loose water injection hose 26 above the filter screen 21 will fall down onto the filter screen 21, hindering the movement of the upper cleaning cover 24, so a magnetic block 20 is provided, and the magnetic block 20 continuously adsorbs and fixes the water injection hose 26 above the filter screen 21 through the magnetic iron sheet, so that the water injection hose 26 is located above the cleaning cover 24, and as the cleaning cover 24 moves, the multiple magnetic iron sheets are pulled and gradually release the adsorption with the magnetic block 20, so the water injection hose 26 6 gradually releases the restriction; and the cleaning cover 24 located above the filter 21 is lower than the water injection hose 26. Therefore, as the cleaning cover 24 moves, the part of the water injection hose 26 that releases the restriction will move to the other side of the cleaning cover 24, that is, fall above the cleaned part of the filter 21, to avoid the water injection hose 26 hindering the movement of the cleaning cover 24. When the cleaning cover 24 is reset, the magnetic iron sheet on the water injection hose 26 gradually resumes the adsorption with the magnetic block 20, so that the water injection hose 26 returns to a straight state; it should be noted that in actual use, the attraction of the magnetic block 20 to the magnetic iron sheet should be greater than the impact force of the water pressure in the water injection hose 26 on the cleaning cover 24, to avoid the situation where the impact force is too large during water injection and causes the water injection hose 26 to fall off prematurely.

[0044] A plurality of rubber columns are fixedly connected to one end of the cleaning cover 24 facing the filter 21, and the ends of the rubber columns away from the cleaning cover 24 are in contact with the surface of the filter 21; when the cleaning cover 24 moves, the rubber columns are driven to move synchronously, and the ends of the rubber columns will generate friction with the surface of the filter 21, causing the dust attached to the surface of the filter 21 to be scraped off, and the dust is cleaned with liquid water, which is beneficial to improving the cleaning effect of the filter 21.

[0045] A guide rod 242 is rotatably connected to the interior of the cleaning cover 24 and located between the dispersing head 241 and the filter screen 21. One end of the guide rod 242 passes through the outside of the cleaning cover 24. A turntable 245 is fixedly connected to the end of the guide rod 242 located outside the cleaning cover 24. A pair of magnets 246 are fixedly connected to both ends of the turntable 245. The pair of magnets 246 have different magnetic properties. A plurality of magnetic pieces 201 are fixedly connected to the inner wall of one side of the receiving frame 2 close to the turntable 245. It should be noted that the spacing between two adjacent magnetic pieces 201 is equal to the spacing between the pair of magnets 246. A pair of positioning plates 247 are fixedly connected to the side of the cleaning cover 24. A pair of springs are fixedly connected between the positioning plates 247 and the turntable 245.

[0046] A plurality of brackets 243 are fixedly connected to the surface of the guide rod 242, and the ends of the brackets 243 away from the guide rod 242 point to the surface of the filter screen 21; when the cleaning cover 24 moves, the turntable 245 moves synchronously. In this process, the magnetic sheet 201 on the inner wall of the receiving frame 2 will intermittently generate magnetic force with the magnet 246. In specific use, when a pair of magnets 246 are opposite to the two magnetic sheets 201, since the pair of magnets 246 have different magnetic properties, the magnetic sheet 201 at this time will exert an attractive force on one of the magnets 246 and a repulsive force on the other magnet 246, so that the magnet 246 exerted with attractive force stretches the spring, and the magnet 246 exerted with repulsive force squeezes the spring. At this time, the magnets 246 at both ends of the turntable 245 move The direction of movement is opposite to that of the rotation disk 245, thereby driving the turntable 245 to rotate, and then when a pair of magnets 246 are separated from the two magnetic pieces 201 and reset by the spring, during the movement of the cleaning cover 24, a pair of magnets 246 and the two magnetic pieces 201 are reciprocating relative to each other, thereby driving the turntable 245 to rotate back and forth, so that the turntable 245 drives the bracket 243 on the surface of the guide rod 242 to rotate back and forth, so that the bottom end of the guide rod 243 intermittently hits the filter screen 21, thereby causing the filter screen 21 to oscillate during cleaning, thereby improving the cleaning effect; further, a flexible plastic block 244 is fixed to the end of the bracket 242 away from the guide rod 242; the bracket 243 drives the flexible plastic block 244 to hit the filter screen 21, thereby preventing the filter screen 21 from being damaged by the impact.

[0047] like Figures 8 to 11As shown, the buffer assembly includes a first valve 271 and a second valve 273. The first valve 271 and the second valve 273 are both fixedly connected to the input end of the pump body 27 and maintained in communication with the input end of the pump body 27. The input end of the first valve 271 is connected and fixedly connected to a first water pipe 272. The bottom end of the first water pipe 272 is connected and fixedly connected to a rectangular water pipe 31. The rectangular water pipe 31 is connected to the water tank 3. The output end of the second valve 273 is connected and fixedly connected to a second water pipe 274. The second water pipe 274 is away from the second valve 273. The end portion is connected to the receiving box 4; when the filter screen 21 is flushed, when the pair of pump bodies 27 are started, the specific upper first valve 271 is opened, the upper second valve 273 is closed, the lower first valve 271 is closed, and the lower second valve 273 is opened. The upper pump body 27 draws liquid water into the rectangular water pipe 31 through the first water pipe 272 to flush the filter screen 21, and the lower pump body 27 draws the liquid water drawn out by the upper pump body 27 into the lower pump body 27 through the second valve 273. The second water pipe 274 in the rectangular shape draws liquid water into the inside of the receiving box 4 to realize the recovery of liquid water, thereby preventing the liquid water used for cleaning the filter 21 from falling downward into the room and affecting the indoor environment. In addition, the microcomputer can control the lower pump body 27 to draw liquid water into the inside of the rectangular water pipe 31, and draw in the cleaning liquid water through the upper pump body 27. The corresponding upper and lower first valves 271 and second valves 273 are opened and closed to replace each other, so that the upper and lower sides of the filter 21 can be flushed during the upper cleaning, thereby improving the cleaning effect and further The material receiving box 4 and the water outlet pipe 12 are connected and fixedly connected with a sewage pipe 6, and the position where the sewage pipe 6 is connected to the material receiving box 4 is higher than the position where the sewage pipe 6 is connected to the water outlet pipe 12; the liquid water entering the material receiving box 4 will enter the water outlet pipe 12 through the sewage pipe 6, and the position where the sewage pipe 6 is connected to the material receiving box 4 is higher than the position where the sewage pipe 6 is connected to the water outlet pipe 12, so the liquid water collected in the material receiving box 4 will smoothly pass through the sewage pipe 6 into the water outlet pipe 12, and then be discharged to the outside through the water outlet pipe 12.

[0048] A water supply pipe 5 is connected and fixed between the water tank 3 and the water outlet pipe 12. The connection position of the water supply pipe 5 and the water outlet pipe 12 is located above the sewage pipe 6, and the top of the water supply pipe 5 is vertically upward; when the central air conditioner is in use, the liquid water discharged from the water outlet pipe 12 will enter through the top of the water supply pipe 5, and then enter the interior of the water tank 3 through the water supply pipe 5, thereby replenishing the liquid water inside the water tank 3 and ensuring that there is sufficient liquid water in the water tank 3 during use.

[0049] A rectangular notch 32 is formed at the top of the rectangular water pipe 31. A rubber pad 33 is fixedly connected to the inside of the rectangular notch 32. A water baffle 34 is fixedly connected to the side of the rubber pad 33. The bottom end of the water baffle 34 is located inside the rectangular water pipe 31. A limiting rod 35 is fixedly connected to the side of the water baffle 34 facing the rubber pad 33. A positioning block 36 fixed to the top of the rectangular water pipe 31 is provided at the end of the limiting rod 35 away from the water baffle 34. The limiting rod 35 passes through the positioning block 36. When liquid water in the rectangular water pipe 31 is not flowing, the rubber pad 33 cooperates with the water baffle 34 to block the rectangular notch 32.

[0050] The top of the rectangular water pipe 31 is fixedly connected to a storage box 37 that is in communication with the rectangular notch 32, and the storage box 37 is filled with cleaning liquid; when the liquid water in the rectangular water pipe 31 is pumped out, the liquid water flows inside the rectangular water pipe 31, and the flowing liquid water impacts the bottom end of the water baffle 34, so that the water baffle 34 is pushed and squeezed by the rubber pad 33, and the water baffle 34 drives the limit rod 35 to move through the positioning block 36, so that the water baffle 34 keeps moving horizontally, and opens the rectangular notch 32 during movement, and the cleaning liquid inside the storage box 37 gradually enters the rectangular water pipe 31 through the rectangular notch 32, so that the liquid water is mixed with the cleaning liquid, thereby improving the cleaning effect of the cleaning liquid; further, the top of the storage box 37 is plugged with a float rod 3 71. A pressing plate 372 is fixedly connected to the top of the float rod 371, and an early warning device fixed to the top of the storage box 37 is provided below the pressing plate 372. As the cleaning liquid inside the storage box 37 decreases, the float rod 371 inserted in the cleaning liquid will gradually move downward with the liquid level of the cleaning liquid, thereby driving the pressing plate 372 at the top to move downward. When the pressing plate 372 presses the early warning device, the switch button at the top of the early warning device is squeezed, and the early warning device starts to send an early warning signal to the external computer to remind the staff to replenish the cleaning liquid. It should be pointed out that the amount of cleaning liquid discharged from the storage box 37 through the rectangular notch 32 each time during use is limited. Therefore, the cleaning liquid inside the storage box 37 can be used continuously for a period of time, and there is no need to frequently replenish the cleaning liquid.
