[0168] The housing 102 may include a first pump 150 for supplying cleaning fluid stored in the cleaning fluid tank 130 to the spray nozzle 240. The first pump 150 is disposed on one side of the cleaning fluid tank 130.

[0169] The outer casing 102 is equipped with a second pump 152 that discharges cleaning fluid stored in the reservoir 200 to the outside. The second pump 152 is located on one side of the reservoir 200. The second pump 152 can discharge the cleaning fluid stored in the reservoir 200 to the outside of the main body 100.

[0170] Reference Figure 8 The structure of the front surface of the cleaning module, as well as the flow path and fan configuration of the cleaning module, are explained.

[0171] The cleaning module 170 includes a cleaning body 172, which has an internal flow path for airflow.

[0172] An intake port 190 and an exhaust port 192 are formed on the front surface 174 of the cleaning body 172. The intake port 190 is located below the exhaust port 192.

[0173] A scraper 250 is disposed on the front surface 174 of the cleaning body 172. The scraper 250 is positioned above the suction port 190 and the discharge port 192. The scraper 250 is positioned above the spray nozzle 240.

[0174] A plurality of suction ports 190 spaced apart in the left-right direction are formed on the front surface 174 of the cleaning body 172. A plurality of discharge ports 192 spaced apart in the left-right direction are formed on the front surface 174 of the cleaning body 172.

[0175] The cleaning module 170 includes a fan 230 for creating airflow toward a flow path formed inside the cleaning body 172. The fan 230 exhausts air to an outlet 192 formed on the front surface 174 of the cleaning body 172. The fan 230 also draws air into an intake 190 formed on the front surface 174 of the cleaning body 172.

[0176] A spray nozzle 240 for spraying cleaning fluid is disposed on the front surface 174 of the cleaning body 172. A plurality of spray nozzles 240 are disposed at intervals along the left-right direction on the front surface of the cleaning body 172.

[0177] The spray nozzle 240 is positioned below the outlet 192. The spray nozzle 240 is positioned above the inlet 190.

[0178] By operating the fan 230, air and cleaning fluid are drawn into the cleaning body 172 through the suction port 190. By operating the fan 230, air is discharged through the exhaust port 192. By operating the first pump 150, the cleaning fluid stored in the cleaning fluid tank 130 is sprayed using the spray nozzle 240.

[0179] Reference Figure 9 The front structure of the cleaning module will be explained.

[0180] The cleaning body 172 includes: a first front surface 174a on which a scraper 250 is disposed; and a second front surface 174b on which a spray nozzle 240 is disposed. The second front surface 174b is disposed rearward than the first front surface 174a. An intake 190 and an exhaust 192 are formed on the second front surface 174b.

[0181] The second front surface 174b is disposed below the first front surface 174a.

[0182] A scraper 250 is disposed on the first front surface 174a of the cleaning body 172. The scraper 250 is mounted on the cleaning body 172. The scraper 250 may be made of rubber. The scraper 250 may be formed of a material different from that of the cleaning body 172.

[0183] The scraper 250 can be closely attached to the window to remove foreign objects adhering to the window. The scraper 250 includes: a fixing part 252, which is fixed to the cleaning body 172; and a protrusion 254, which protrudes from the front surface 174 of the cleaning body 172 toward the window.

[0184] The fixing part 252 has an 'H' shaped cross-section and is inserted into the inside of the cleaning body 172. The fixing part 252 can fix the scraper 250 to the cleaning body 172.

[0185] The protrusion 254 protrudes forward from the front surface 174 of the cleaning body 172. The protrusion 254 may have a shape in which its width in the vertical direction narrows towards the front. The protrusion 254 may have a shape in which its upper surface slopes in a manner in which its width narrows towards the front.

[0186] An outlet 192 and an inlet 190 are disposed below the scraper 250. The inlet 190 is disposed below the outlet 192.

[0187] The upper surface of the outlet 192 slopes downwards towards the front. Therefore, air discharged through the outlet 192 can be discharged at a downward angle.

[0188] The upper surface of the intake 190 slopes upwards towards the front. Therefore, cleaning fluid sprayed from above the intake 190 can flow into the intake 190. Furthermore, foreign matter falling from the window through the exhaust port 192 can also flow into the intake 190.

[0189] A spray nozzle 240 is disposed above the inlet 190. The spray nozzle 240 is disposed on the second front surface 174b. The front end of the spray nozzle 240 may be disposed at a position rearward than the first front surface 174a.

[0190] That is, the spray nozzle 240 is configured to be further away from the window than the first front surface 174a. The scraper 250 protrudes forward from the spray nozzle 240.

[0191] An intake port 190 and an exhaust port 192 are provided on the second front surface 174b.

[0192] Reference Figure 10 The shell groove of the main body and the mover are described.

[0193] Shell grooves 122 are formed at both ends of the first surface 112 of the outer casing 102. The shell grooves 122 extend in the vertical direction. The shell grooves 122 form grooves that are recessed from the first surface 112 of the outer casing 102 in the inward direction.

[0194] The track 18, which is configured on the frame 11, can be configured within the housing groove 122. The main body 100 can be mounted on the frame 11 in a state where a portion of the track 18 is inserted into the housing groove 122.

[0195] The mover 124 is disposed within the housing groove 122. The mover 124 can move the main body 100 in the vertical direction.

[0196] After the scraper 250 is pressed against the window 1, the mover 124 moves the housing 102 downward.

[0197] The mover 124 can be a structure that moves by magnetic levitation. Therefore, an electromagnet can be configured in the track 18. The electromagnet configured in the track 18 can move the mover 124 by switching its polarity.

[0198] Furthermore, the mover 124 includes a gear structure that can rotate, thereby moving the main body 100. At this time, a track gear (not shown) that meshes with the gear can be arranged on the track 18.

[0199] Figure 11 The gear module and drive gear configured in the frame are described.

[0200] The lower frame 16 is equipped with a gear module 20. The gear module 20 includes at least one frame gear 22. The frame gear 22 is configured to rotate inside the lower frame 16. The frame gear 22 is capable of rotating in a fixed position.

[0201] The frame gear 22 may include a cover made of rubber. Furthermore, other covers made of rubber may be disposed around the outer periphery of the frame gear 22.

[0202] When the frame gear 22 rotates, it may rub against the bottom surface of the window frame 2. Therefore, when the frame gear 22 rotates, it can move the frame 11 in the left and right directions while rubbing against the window frame 2.

[0203] The frame gear 22 may include a pair of frame gears 22 separated in the left-right direction. A drive gear 116 is arranged between the pair of frame gears 22. The drive gear 116 meshes with each of the pair of frame gears 22.

[0204] Therefore, by rotating the drive gear 116, the pair of frame gears 22 arranged on both sides can rotate in the same direction. A drive motor 118 for rotating the drive gear 116 can be arranged on one side of the drive gear 116.

[0205] Reference Figure 12 The vertical movement of the window cleaning device is explained.

[0206] The main body 100 moves vertically along the frame 11 via the operation of the mover 124. As the main body 100 moves, the length of the mesh 294 changes. The upper end of the mesh 294 is fixed to the upper frame 14. Therefore, the mesh 294 can be positioned from the upper frame 14 up to the position where the main body 100 is located.

[0207] The main body 100 can move along the frame 11 while wiping away foreign objects attached to the window 1. The cleaning module 170 of the main body 100 can spray air toward the window to wipe away foreign objects attached to the window 1. The cleaning module 170 can spray cleaning fluid toward the window.

[0208] The cleaning module 170 can wipe away foreign objects attached to the window 1 while moving downwards along the window 1.

[0209] The cleaning module 170 can clean the window while moving downwards along the frame 11. When the main body 100 moves to the lower end of the frame 11, the screen 294 can be configured to block the window.

[0210] Reference Figure 13 The left-right movement of the window cleaning device is explained.

[0211] The window cleaning device 10 moves in the left-right direction via the frame 11. The frame 11 can move in the left-right direction on the window frame 2.

[0212] As the frame 11 moves, the main body 100 configured on the frame 11 also moves.

[0213] When the main body 100 is positioned at the lower end of the frame 11, the drive gear 116 of the main body 100 is connected to the gear module 20 of the frame 11. Specifically, the drive gear 116 meshes with the frame gear 22.

[0214] When the drive motor 118 of the main body 100 is working, the drive gear 116 causes the frame gear 22 to rotate. When the frame gear 22 rotates, the frame 11 can move in the left and right directions in a state configured in the window frame 2.

[0215] The frame gear 22 is in close contact with the window frame 2, and through friction, the frame 11 can be moved.

[0216] The frame 11 can move in the left and right directions while the main body 100 is moved to the lower end of the frame 11. While the frame 11 is moving, the main body 100 can clean one side of the window while moving in the up and down directions.

[0217] Reference Figure 14 The module moving device that causes changes to the configuration of the cleaning module is explained.

[0218] The main body 100 includes a module moving device 270 that changes the configuration of the cleaning module 170. The module moving device 270 can move the cleaning module 170 in the front-back direction.

[0219] The module moving device 270 brings the scraper 250 into contact with or away from the window 1. The module moving device 270 also keeps the scraper 250 in close contact with the window 1.

[0220] The module moving device 270 includes: a module motor 272; and a transmission component 276, which rotates by the operation of the module motor 272, thereby moving the cleaning module 170.

[0221] The transfer member 276 is rotatably disposed below the cleaning body 172. The transfer member 276 may have a rod-like shape that is longer in the left-right direction.

[0222] The transmission component 276 moves the cleaning body 172 by rotating using the rotational force of the module motor 272.

[0223] The modular moving device 270 includes a modular motor gear 274 that rotates due to the operation of the modular motor 272.

[0224] The transmission component 276 includes: a first transmission gear 280 that meshes with a module motor gear 274; a pair of second transmission gears 282 that are connected to the lower surface 178 of the cleaning body 172; and a rotating rod 278 that transmits the rotational force of the first transmission gear 280 to the pair of second transmission gears 282 respectively.

[0225] A pair of second transmission gears 282 may be arranged at both ends of the rotating rod 278. A first transmission gear 280 is arranged between the pair of second transmission gears 282.

[0226] The first transmission gear 280 and a pair of second transmission gears 282 are connected to the rotating rod 278 and rotate together.

[0227] A rack 180 that meshes with the transmission member 276 may be disposed on the lower surface 178 of the cleaning body 172. A pair of racks 180 that are spaced apart on both sides and extend in the front-back direction may be disposed on the lower surface 178 of the cleaning body 172.

[0228] Reference Figure 15 The pressure sensor used to sense the contact of the scraper is described.

[0229] The cleaning module 170 includes a pressure sensor 264 for sensing whether the scraper 250 is in close contact with the window. When the scraper 250 contacts the window, a force that pushes the scraper 250 backward can be transmitted to the pressure sensor 264.

[0230] Pressure sensor 264 can precisely sense whether scraper 250 is in contact with the window.

[0231] The cleaning module 170 includes a pressure transmission unit 266. The pressure transmission unit 266 can transmit the force generated at the scraper 250 to the pressure sensor 264. The pressure transmission unit 266 can be formed in the form of an air tube. Therefore, when the scraper 250 contacts the window 1, the air inside the pressure transmission unit 266 is compressed, thereby enabling the force to be transmitted to the pressure sensor 264.

[0232] Reference Figure 16 The movement of the cleaning module is explained.

[0233] like Figure 16 As shown in (a), the cleaning module 170 can be configured at a first position P1, separated from the window 1 by a predetermined interval. Figure 16 As shown in (b), the cleaning module 170 can be configured at a second position P2 in contact with the window 1.

[0234] The first position P1 can be a state where the scraper 250 of the cleaning module 170 is not in contact with the window 1. The first position P1 can also be a state where the pressure sensor 264 of the cleaning module 170 does not sense the pressure applied by the scraper 250.

[0235] When the main body 100 moves upward, the cleaning module 170 can be configured in the first position P1.

[0236] The first position P1 can be the state after the cleaning module 170 is moved backward by the module moving device 270.

[0237] The second position P2 can be the state in which the scraper 250 of the cleaning module 170 is in contact with the window 1. The second position P2 can also be the state in which the pressure sensor 264 of the cleaning module 170 senses the pressure applied by the scraper 250.

[0238] When the main body 100 moves downward, the cleaning module 170 can be configured in the second position P2.

[0239] The second position P2 can be the state after the module moving device 270 moves the cleaning module 170 forward.

[0240] The module moving device 270 moves the cleaning module 170 once based on the distance between the module and the window 1 sensed by the ultrasonic sensor 260. Then, the module moving device 270 moves the cleaning module 170 a second time based on pressure information sensed by the pressure sensor 264.

[0241] That is, based on the distance sensed by the ultrasonic sensor 260 at the first position P1, the module moving device 270 causes the cleaning module 170 to move once. The position of the cleaning module 170 after this movement can be the second position P2 or a position between the first position P1 and the second position P2.

[0242] The accuracy of the distance between window 1 and cleaning module 170 sensed by ultrasonic sensor 260 may not be high.

[0243] Furthermore, even if the module moving device 270 is activated to move the cleaning module 170 based on the information sensed by the ultrasonic sensor 260, the scraper 250 may not adhere tightly to the window 1 with the desired level of pressure.

[0244] Therefore, based on the pressure information sensed by the pressure sensor 264, the cleaning module 170 is moved a second time. At this time, the scraper 250 can be pressed against the window 1 to a degree that allows it to remove foreign objects attached to the window 1 while moving downwards.

[0245] That is, the module moving device 270 can move the cleaning module 170 so that the pressure sensed by the pressure sensor 264 is formed between the first set pressure and the second set pressure.

[0246] The first set pressure can be the pressure generated at the moment when the scraper 250 begins to contact the window 1. The second set pressure can be the pressure at the moment when the force generated by the friction between the scraper 250 and the window 1 becomes greater than the force of the mover 124 moving the main body 100 in the vertical direction.

[0247] Therefore, when the second set pressure is exceeded, even if the mover 124 is working, the main body 100 may not move in the vertical direction.

[0248] After the scraper 250 is pressed against the window 1, the mover 124 moves the housing 102 downward.

[0249] After the module moving device 270 presses the cleaning module 170 against the window 1, the mover 124 and the first pump 150 begin to operate. However, before the module moving device 270 moves the cleaning module 170 toward the window 1, the first pump 150 operates temporarily to spray cleaning fluid through the spray nozzle 240.

[0250] By spraying cleaning fluid onto the window 1 using the first pump 150, the friction between the window 1 and the scraper 250 can be reduced. Therefore, the force required for the mover 124 to move the main body 100 downwards can be reduced.

[0251] The preferred embodiments of this disclosure have been illustrated and described above. However, this disclosure is not limited to the specific embodiments described above. Various modifications can be made by those skilled in the art without departing from the spirit of this disclosure as claimed in the claims. Moreover, such modifications should not be understood separately from the technical spirit or prospects of this disclosure.
