Specifically, the indoor installation is an indoor unit, the indoor unit is internally provided with a pipe for conveying refrigerant, and the indoor unit is also internally provided with a water pump for conveying cooling water and a fan for air extraction. During the refrigeration operation, the fan draws indoor air into contact with the pipe for conveying refrigerant. In this process, the pipe absorbs heat from the air, causing the water vapor in the air to liquefy. Then the liquefied water is pumped out of the pipe to the outdoor.

[0003] During the use of the central air conditioner, the central air conditioner can monitor the indoor temperature in real time, and automatically start the air conditioner when the indoor temperature does not reach the predetermined value. During the refrigeration process, the indoor unit of the indoor air conditioner extracts indoor air, which needs to pass through a filter assembly to filter the dust and other impurities inside, so as to prevent the dust and other impurities in the air from entering the indoor unit and affecting the use. However, after a period of use, the degree of clogging of the filter assembly by dust gradually increases, so that the air content entering the indoor unit per unit time decreases, thereby reducing the heat exchange speed between the indoor air and the indoor unit, and thus reducing the indoor cooling speed. Therefore, the air conditioner needs to be turned on for a longer time to reduce the indoor temperature to the predetermined value. In this process, the fan and the water pump of the indoor unit need to be continuously turned on, thereby consuming a large amount of electric energy.

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[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 housing 1. An air outlet 11 is installed on the side of the housing 1. A water outlet pipe 12 is connected and fixed to the side of the housing 1 opposite to the air outlet 11. A receiving frame 2 is connected and fixed to the bottom of the housing 1. A return air outlet is installed on the bottom surface of the receiving frame 2. The return air outlet is a prior art and is not shown in this application.

[0038] A filter screen 21 is fixedly connected inside the receiving frame 2. A pair of cleaning covers 24 are symmetrically arranged at the upper and lower ends of the filter screen 21. A dispersing 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 screen 21. A screw 22 is engaged inside the rectangular nut 23. Both ends of the screw 22 extend to the outside of the receiving frame 2. A pair of motors 25 are fixedly connected to the end of the receiving frame 2. The output end of the motor 25 is fixedly connected to the end of the screw 22.

[0039] A water injection hose 26 is fixedly connected to the surface of the cleaning cover 24. A pair of pump bodies 27 are fixedly connected to the end of the receiving frame 2 away from the motor 25. A water tank 3 is fixedly connected to the side of the receiving frame 2 on one side of the pump body 27. A buffer component is connected between the pump body 27 and the water tank 3.

[0040] After the indoor unit of an air conditioner has been used for a period of time, the filter components become increasingly clogged with dust, reducing the amount of air entering the indoor unit per unit time. This leads to a decrease in the heat exchange rate between the indoor air and the indoor unit, resulting in a slower cooling rate. Consequently, the air conditioner needs to run for a longer period to lower the indoor temperature to the predetermined value. During this process, the fan and water pump of the indoor unit need to run continuously, consuming more electrical energy. Therefore, it is necessary to optimize the structure of the indoor unit based on the above requirements. To solve the above problems, this embodiment of the invention includes multiple structures such as a cleaning cover 24 and a dispersion head 241 to achieve automatic cleaning of the filter screen 21. The specific usage process is as follows: When the air conditioner is in use, the fan inside the indoor unit casing 1 draws indoor air in through the return air vent. During the drawing process, dust and other impurities inside the air are filtered by the filter screen 21. Then, the air comes into contact with the pipes that transport refrigerant inside the casing 1. The pipes absorb heat from the air, causing the water vapor in the air to liquefy. Then, the water pump draws the liquefied liquid water out to the outside through the pipes. This embodiment of the invention is not shown in the accompanying drawings.

[0041] In this embodiment of the invention, the motor 25, pump body 27, and other electrical control structures are all controlled by a microcomputer. After the air conditioner has been used for a period of time, the motor 25 and pump body 27 are started. The motor 25 drives the screw 22 to rotate. When the screw 22 rotates, it engages with the rectangular nut 23. The rectangular nut 23 is fixedly connected to the cleaning cover 24. The filter screen 21 is fixedly connected to 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. The frame restricts the position of the cleaning cover 24. At the same time, the pump body 27 starts, drawing liquid water from the water tank 3 through the buffer assembly, and then injecting it into the cleaning cover 24 through the water injection hose 26. Afterward, it is sprayed onto the surface of the filter screen 21 through the dispersing head 241. The dispersing head 241 is a block structure with multiple holes on its surface. When the liquid water passes through the dispersing head 241, the dispersing head 241 can... The liquid water is atomized and dispersed, allowing it to be evenly sprayed onto the surface of the filter screen 21. It should be noted that the upper cleaning hood 24 sprays the liquid water, while the lower cleaning hood 24 draws it in. Therefore, after passing through the filter screen 21, the liquid water is drawn in through the lower cleaning hood 24. As the cleaning hood 24 moves, the entire filter screen 21 is cleaned, and the dust clogging its surface is removed. Afterward, the cleaning hood 24 is reset, and the motor 25 and pump 27 are shut off, achieving automatic cleaning of the filter screen 21. The structure of the indoor unit is optimized, and liquid water is prevented from falling during cleaning, thus avoiding affecting indoor cleanliness. After the filter screen 21 is cleaned, the amount of air entering the indoor unit per unit time is normal, resulting in normal indoor cooling speed. The air conditioner does not need to run for a longer period to lower the indoor temperature to the preset value, and the indoor unit's fan and water pump do not need to run continuously, thereby saving energy.

[0042] It should be noted that the temperature sensor described in this embodiment of the invention is installed outside the water pump to monitor the operating temperature of the water pump. When the temperature sensor detects that the water pump temperature is too high, it will send a signal back to the system controller. Then, the system controller sends an operating command to the heat dissipation component, causing the heat dissipation component to run and dissipate heat from the water pump. At the same time, it sends an operating command to the motor 25 and the pump body 27 to clean the filter screen 21, thereby solving the problem of excessive water pump temperature from the root and achieving the effect of energy saving for the water pump. It should be noted that the heat dissipation component is existing technology and can be implemented in various ways, such as using a fan for heat dissipation or using water flow for heat dissipation, i.e., air cooling or water cooling in the conventional sense. These will not be specifically described in this embodiment of the invention.

[0043] like Figures 4 to 7As shown, multiple magnetic iron pieces are linearly and uniformly fixed to the side of the water injection hose 26; multiple magnetic blocks 20 are fixed to the side of the receiving frame 2 near the water injection hose 26, and the magnetic blocks 20 continuously attract the magnetic iron pieces; when the cleaning hood 24 moves, the water injection hose 26 connected to the cleaning hood 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 cleaning hood 24 above. Therefore, magnetic blocks 20 are provided. The magnetic blocks 20 continuously attract and fix the water injection hose 26 above the filter screen 21 through the magnetic iron pieces, so that the water injection hose 26 is located above the cleaning hood 24. As the cleaning hood 24 moves, the multiple magnetic iron pieces are pulled and gradually release the attraction from the magnetic blocks 20. Therefore, the water injection hose 26... 6. Gradually release the restriction; the cleaning cover 24, located above the filter screen 21, is lower than the water injection hose 26. Therefore, as the cleaning cover 24 moves, the portion of the water injection hose 26 that has been released from restriction will move to the other side of the cleaning cover 24, that is, fall above the cleaned portion of the filter screen 21, thus preventing the water injection hose 26 from obstructing the movement of the cleaning cover 24. When the cleaning cover 24 is reset, the magnetic iron piece on the water injection hose 26 gradually regains its attraction to the magnetic block 20, causing the water injection hose 26 to return to a taut state. It should be noted that in actual use, the attraction of the magnetic block 20 to the magnetic iron piece should be greater than the impact force of the water pressure inside the water injection hose 26 on the cleaning cover 24, to avoid the situation where the water injection hose 26 falls off prematurely due to excessive impact force during water injection.

[0044] Multiple rubber pillars are fixed to one end of the cleaning cover 24 facing the filter screen 21. The ends of the rubber pillars away from the cleaning cover 24 are in contact with the surface of the filter screen 21. When the cleaning cover 24 moves, the rubber pillars are driven to move synchronously. The ends of the rubber pillars will rub against the surface of the filter screen 21, causing the dust attached to the surface of the filter screen 21 to be scraped off. Combined with liquid water, the dust is cleaned, which helps to improve the cleaning effect of the filter screen 21.

[0045] Inside the cleaning hood 24, between the dispersing head 241 and the filter screen 21, a guide rod 242 is rotatably connected. One end of the guide rod 242 extends to the outside of the cleaning hood 24. A turntable 245 is fixed to the end of the guide rod 242 outside the cleaning hood 24. A pair of magnets 246 are fixed to both ends of the turntable 245. The pair of magnets 246 have different magnetic properties. Multiple magnetic pieces 201 are fixed to the inner wall of the receiving frame 2 near the turntable 245. It should be noted that the distance between two adjacent magnetic pieces 201 is equal to the distance between a pair of magnets 246. A pair of positioning plates 247 are fixed to the side of the cleaning hood 24. A pair of springs are fixed between the positioning plates 247 and the turntable 245.

[0046] Multiple supports 243 are fixed to the surface of the guide rod 242, with the ends of the supports 243 away from the guide rod 242 pointing towards the surface of the filter screen 21. When the cleaning hood 24 moves, the turntable 245 moves synchronously. During this process, the magnetic sheet 201 on the inner wall of the receiving frame 2 intermittently generates magnetic force with the magnet 246. In practical use, when a pair of magnets 246 are opposite to two magnetic sheets 201, because the pair of magnets 246 have different magnetic properties, the magnetic sheet 201 will exert an attractive force on one magnet 246 and a repulsive force on the other. This causes the attracted magnet 246 to stretch the spring, while the repulsive magnet 246 compresses the spring. At this time, the magnets 246 at both ends of the turntable 245 move... The opposite directions of movement cause the turntable 245 to rotate. After the pair of magnets 246 separate from the two magnetic pieces 201, they are reset by the spring. During the movement of the cleaning cover 24, the pair of magnets 246 and the two magnetic pieces 201 reciprocate, thereby causing the turntable 245 to rotate reciprocally. This causes the turntable 245 to drive the support 243 on the surface of the guide rod 242 to rotate reciprocally, causing the bottom end of the support 243 to intermittently impact the filter screen 21, thereby causing the filter screen 21 to vibrate during cleaning and improving the cleaning effect. Furthermore, a flexible plastic block 244 is fixedly attached to the end of the support 243 away from the guide rod 242. The support 243 drives the flexible plastic block 244 to impact the filter screen 21, which protects the filter screen 21 from damage.

[0047] like Figures 8 to 11As shown, the buffer assembly includes a first valve 271 and a second valve 273. Both the first valve 271 and the second valve 273 are fixedly connected to the input end of the pump body 27 and maintain communication with the input end of the pump body 27. A first water pipe 272 is fixedly connected to the input end of the first valve 271, and a rectangular water pipe 31 is fixedly connected to the bottom end of the first water pipe 272. The rectangular water pipe 31 is connected to the water tank 3. A second water pipe 274 is fixedly connected to the output end of the second valve 273, and the second water pipe 274 is located away from the second valve 273. The end of the filter screen 21 is connected to a receiving box 4. When the filter screen 21 is washed, when the pair of pumps 27 are started, the upper first valve 271 is opened and 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 27 draws liquid water from the inside of the rectangular water pipe 31 through the first water pipe 272 to wash the filter screen 21. The lower pump 27 draws the liquid water drawn out by the upper pump 27 into the filter screen 21 and connects it to the lower pump through the lower second valve 273. The second water pipe 274 draws liquid water into the receiving box 4, achieving liquid water recycling and preventing liquid water from falling into the room during filter cleaning 21 and affecting the indoor environment. Additionally, the microcomputer controls the lower pump 27 to draw liquid water from the rectangular water pipe 31, and the upper pump 27 to draw cleaning liquid water. Correspondingly, the upper and lower first valves 271 and second valve 273 open and close, allowing for rinsing of both sides of the filter 21 during cleaning, improving the cleaning effect and further... The receiving box 4 and the outlet pipe 12 are connected by a drain pipe 6. The position where the drain pipe 6 is connected to the receiving box 4 is higher than the position where the drain pipe 6 is connected to the outlet pipe 12. The liquid water that enters the receiving box 4 will enter the outlet pipe 12 through the drain pipe 6. Since the position where the drain pipe 6 is connected to the receiving box 4 is higher than the position where the drain pipe 6 is connected to the outlet pipe 12, the liquid water collected inside the receiving box 4 will smoothly enter the outlet pipe 12 through the drain pipe 6 and then be discharged outdoors through the outlet pipe 12.

[0048] A water supply pipe 5 is fixedly connected between the water tank 3 and the outlet pipe 12. The connection point between the water supply pipe 5 and the outlet pipe 12 is located above the drain pipe 6, and the top of the water supply pipe 5 is vertically upward. When the central air conditioning is in use, the liquid water discharged from the 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 the water tank 3 maintains sufficient liquid water during use.

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

[0050] A storage tank 37, connected to a rectangular notch 32, is fixedly connected to the top of a rectangular water pipe 31. The storage tank 37 is filled with cleaning fluid. When liquid water is drawn out from inside the rectangular water pipe 31, the liquid water flows inside the pipe and impacts the bottom of a baffle plate 34, causing the baffle plate 34 to be pushed and squeeze the rubber pad 33. The baffle plate 34 also moves the limiting rod 35 through the positioning block 36, keeping the baffle plate 34 moving horizontally. During this movement, the rectangular notch 32 is opened, and the cleaning fluid inside the storage tank 37 gradually enters the rectangular water pipe 31 through the notch 32, mixing the liquid water with the cleaning fluid and thus improving the cleaning effect. Furthermore, a float rod 3 is inserted into the top of the storage tank 37. 71. A pressure plate 372 is fixedly attached to the top of the float 371. Below the pressure plate 372, an alarm device is fixedly attached to the top of the storage tank 37. As the cleaning fluid inside the storage tank 37 decreases, the float 371 inserted inside the cleaning fluid will gradually move downward with the liquid level, thereby driving the pressure plate 372 at the top to move downward. When the pressure plate 372 presses against the alarm device, the switch button at the top of the alarm device is pressed, and the alarm device is activated to send an alarm signal to an external computer, reminding the staff to replenish the cleaning fluid. It should be noted that the amount of cleaning fluid discharged from the storage tank 37 through the rectangular notch 32 each time is limited. Therefore, the cleaning fluid inside the storage tank 37 can be used continuously for a period of time, and there will be no need to frequently replenish the cleaning fluid.
