[0048] See also Figures 1-10The figure shows an embodiment of a full-coverage spray structure proposed by the present invention. The full-coverage spray structure 100 comprises a water supply pipe 10, a spray arm 20, and a spray pipe 30. The water supply pipe 10 is connected to the water supply line and is used to direct water into the full-coverage spray structure 100. The spray arm 20 is rotatably mounted on the water supply pipe 10. Multiple spray pipes 30 are connected to the water supply pipe 10. The spray pipes 30 are used to spray areas outside the spray range of the spray arm 20. The spray pipes 30 have a tube body 31 and a spray head 32 at the end of the tube body 31 away from the water supply pipe 10. The combination of the spray arm 20 and the multiple spray pipes 30 achieves full-coverage spraying, ensuring that every corner of the dishwasher is cleaned, greatly improving the cleaning effect. The multiple spray pipes 30 increase the spray water volume and pressure, enhancing the rinsing force, and more effectively remove stubborn stains, leaving dishes cleaner and tidier. By rationally arranging the combination of the spray arm 20 and the spray pipe 30, a full coverage spraying effect can be achieved while using less water, thus avoiding waste of water resources; at the same time, since the cleaning is more thorough, the number and time of cleaning can be reduced, thereby reducing energy consumption.

[0049] In some embodiments of the present application, the spray pipe 30 extends outward along the plane where the water pipe 10 is located, that is, the spray pipe 30 and the water pipe 10 are in the same water surface and do not extend in the up and down directions, which is conducive to the placement of the shelf.

[0050] In some embodiments of the present application, the spray pipe 30 is used to spray the corner areas of the circular spray range of the spray arm 20, and the spray head 32 is located above or below the corner areas. The spray arm 20 sprays in a circular trajectory, but the corner areas easily become blind spots for cleaning; setting the spray head 32 above or below the corner areas can directly spray these easily overlooked areas, effectively eliminating cleaning dead corners. The spray head 32 cooperates with the circular spray range of the spray arm 20 to form a more complete cleaning coverage area; the spray position above or below can flush the corner areas from different angles, so that the water flow can better cover the entire internal space of the dishwasher. Two adjacent spray arms 20 are provided on the water inlet pipe 10, and six spray pipes 30 are provided on the water inlet pipe 10.

[0051] In some embodiments of the present application, the spray arm 20 is provided with multiple spray holes for spraying upward, and the full-coverage spray structure 100 can be configured to spray upward or downward. The spray arm 20 is located below the water supply pipe 10, which facilitates the installation of the spray arm 20 and allows the water to spray upward and then fall back onto the tableware below.

[0052] In some embodiments of the present application, the spray head 32 is arranged at the end of the pipe body 31, and a mounting structure is arranged between the spray head 32 and the pipe body 31. The mounting structure has a mounting protrusion 321 arranged on the spray head 32 and a mounting groove 311 arranged on the pipe body 31. The mounting groove 311 is matched with the mounting protrusion 321 and extends in the axial direction. The design of the mounting protrusion 321 and the mounting groove 311 makes the connection between the spray head 32 and the pipe body 31 more convenient and fast. The mounting groove 311 extends in the axial direction, so that the mounting protrusion 321 can be effectively fixed in the axial direction after installation. The axial displacement of the spray head 32 caused by water flow impact or other external forces during use can be prevented, and the stability of the connection can be ensured. The spray head 32 is fixedly arranged in the pipe body 31, and a spray opening 322 for upward spraying is arranged on the spray head 32.

[0053] In some embodiments of the present application, the spray head 32 can be rotatable, and the reverse force of the water flow can push the spray head 32 to rotate. Specifically, the spray head 32 is rotatably arranged on the pipe body 31, and the mounting structure further has a circumferential annular groove arranged on the pipe body 31 and connected with one end of the mounting groove 311. The mounting protrusion 322 is movably arranged in the annular groove. A spray opening for pushing the spray head 32 to rotate is arranged on the spray head 32. The axis of the spray head 32 is arranged horizontally, and the axis of the spray head 32 coincides with the axis of the pipe body 31. The rotatable spray head 32 can continuously rotate under the action of the reverse force of the water flow, so that the water flow can be uniformly sprayed to a larger area, and the spraying effect can be enhanced. The rotatable spray head can spray water flow from different angles, so that the water flow can be uniformly distributed in the cleaning area, and the problems of local over-cleaning or insufficient cleaning can be avoided.

[0054] In some embodiments of the present application, the water guide pipe 10 has a plug-in assembly structure of the first water pipe 11 and the second water pipe 12. The plug-in assembly structure has a plug-in part 111 arranged at the end of the first water pipe 11 and a plug-in sleeve 121 arranged outside the plug-in part 111. A plurality of buckles 112 extending radially outward are arranged on the plug-in part 111, and a plurality of buckle holes 122 matched with the buckles 112 are arranged on the plug-in sleeve 121. The plug-in assembly structure makes the connection of the first water pipe 11 and the second water pipe 12 very convenient. The first water pipe 11 is only needed to be inserted into the plug-in sleeve 121 of the second water pipe 12, and the buckles 112 will be automatically buckled into the buckle holes 122, so that the connection can be completed. When the dishwasher is running, the water guide pipe 10 needs to withstand a certain water pressure and water flow impact force. The stable connection structure can ensure that the water guide pipe will not be loose or fall off, so that the normal operation of the dishwasher can be ensured. The cooperation of the plug-in part 111 and the plug-in sleeve 112 can form a good seal to prevent water leakage.

[0055] In some embodiments of the present application, the insertion sleeve 12 is provided with a plurality of partition openings 123 in communication with the end; the partition openings 123 are axially arranged, the clamping hole 122 is located between two partition openings 123, the insertion of the insertion part 111 of the first water pipe 11 into the insertion sleeve 121 of the second water pipe 12 can be realized by the radial outward deformation of the sleeve wall of the insertion sleeve 12; the radial section of the insertion sleeve 121 along the end of the partition opening 123 passes through the clamping hole 122. The partition openings 123 are provided to make the sleeve wall of the insertion sleeve 121 have a certain elastic deformation capacity, when the insertion part 111 of the first water pipe 11 is inserted into the insertion sleeve 121 of the second water pipe 12, the sleeve wall of the insertion sleeve 121 can be deformed radially outward to adapt to the size of the insertion part 111, so that the insertion process is more smooth. The clamping hole 122 is located between two partition openings 123, when the insertion part 111 is inserted into the insertion sleeve 121, the buckle 112 can be accurately clamped into the clamping hole 122; the existence of the partition opening makes the sleeve wall around the clamping hole 122 have a certain elasticity, which can better fix the buckle 112 and prevent it from loosening or falling off.

[0056] In some embodiments of the present application, the second water pipe 12 has a second body 120, a connecting edge 124 extending radially outward along one end of the second body 120, and the insertion sleeve 121 formed by extending radially along the outer circle of the connecting edge 124; a sealing ring 13 is arranged between the insertion part 111 and the connecting edge 124. The sealing ring 13 is arranged to form a reliable seal at the connection part of the first water pipe 11 and the second water pipe 12, and the sealing ring 13 can prevent water leakage from the connection part between the insertion part 111 and the connecting edge 124; during installation, only the sealing ring 13 needs to be placed between the insertion part 111 and the connecting edge 124, and then the insertion part 111 is inserted into the insertion sleeve. The sealing ring will automatically fill the gap and form a seal, without the need for complex sealing treatment. Embodiments

[0057] Referring to Figures 1-10 As shown in the drawings, a dishwasher with the full-coverage spraying structure is provided, which realizes full-coverage spraying through the combination of the spraying arm 20 and the plurality of spraying pipes 30, greatly improving the cleaning effect; the full-coverage spraying effect can be realized with less water, avoiding the waste of water resources.

[0058] In some embodiments of the present application, a full-coverage spray structure 100 includes a water supply pipe 10, a spray arm 20, and a spray pipe 30. The water supply pipe 10 is connected to the water supply line and is used to direct water into the full-coverage spray structure 100. The spray arm 20 is rotatably mounted on the water supply pipe 10. Multiple spray pipes 30 are connected to the water supply pipe 10. The spray pipes 30 are used to spray areas outside the spray range of the spray arm 20. The spray pipe 30 has a tube body 31, and a spray head 32 is provided at the end of the tube body 31 away from the water supply pipe 10. The combination of the spray arm 20 and the multiple spray pipes 30 achieves full-coverage spraying, allowing for comprehensive cleaning of the dishwasher interior, ensuring that every corner is cleaned, significantly improving the cleaning effect. Multiple spray pipes 30 can increase the amount and pressure of the sprayed water, enhancing the rinsing force, and more effectively cleaning stubborn stains, leaving dishes cleaner and tidier. By rationally arranging the combination of the spray arm 20 and the spray pipe 30, a full coverage spraying effect can be achieved while using less water, thus avoiding waste of water resources; at the same time, since the cleaning is more thorough, the number and time of cleaning can be reduced, thereby reducing energy consumption.

[0059] In some embodiments of the present application, the spray pipe 30 is arranged to extend horizontally outward along the water diversion pipe 10, that is, the spray pipe 30 and the water diversion pipe 10 are in the same horizontal layer and do not extend in the up and down directions, which is conducive to the placement of the shelf.

[0060] In some embodiments of the present application, the spray pipe 30 is used to spray the corner areas of the circular spray range of the spray arm 20, and the spray head 32 is located above or below the corner areas. The spray arm 20 sprays in a circular trajectory, but the corner areas easily become blind spots for cleaning; setting the spray head 32 above or below the corner areas can directly spray these easily overlooked areas, effectively eliminating cleaning dead corners. The spray head 32 cooperates with the circular spray range of the spray arm 20 to form a more complete cleaning coverage area; the spray position above or below can flush the corner areas from different angles, so that the water flow can better cover the entire internal space of the dishwasher. Two adjacent spray arms 20 are provided on the water inlet pipe 10, and six spray pipes 30 are provided on the water inlet pipe 10.

[0061] In some embodiments of the present application, the spray arm 20 is provided with multiple spray holes for spraying upward, and the full-coverage spray structure 100 can be configured to spray upward or downward. The spray arm 20 is located below the water supply pipe 10, which facilitates the installation of the spray arm 20 and allows the water to spray upward and then fall back onto the tableware below.

[0062] In some embodiments of the present application, the spray head 32 is provided at the end of the tube body 31, and a mounting structure is provided between the spray head 32 and the tube body 31. The mounting structure comprises a mounting protrusion 321 provided on the spray head 32 and a mounting groove 311 provided on the tube body 31. The mounting groove 311 matches the mounting protrusion 321, and the mounting groove 311 extends in the axial direction. The design of the mounting protrusion 321 and the mounting groove 311 makes the connection between the spray head 32 and the tube body 31 simpler and faster. The mounting groove 311 extends in the axial direction, so that the mounting protrusion 321 can be effectively fixed in the axial direction after installation, which can prevent the spray head 32 from axial displacement due to water flow impact or other external forces during use, thereby ensuring the stability of the connection. The spray head 32 is fixed in the tube body 31, and a nozzle 322 for spraying upward is provided on the spray head 32.

[0063] In some other embodiments of the present application, the spray head 32 can be configured to be rotatable, and the reverse force of the water flow can be used to push the spray head 32 to rotate. Specifically, the spray head 32 can be rotatably mounted on the tube body 31, and the mounting structure also has a circumferential annular groove on the tube body 31 that is connected to one end of the mounting groove 311, and the mounting protrusion 322 is movably located in the annular groove. A nozzle that can push the spray head 32 to rotate is provided on the spray head 32, and the axis of the spray head 32 is arranged horizontally, and the axis of the spray head 32 is arranged to coincide with the axis of the tube body 31. The rotatable spray head 32 can continuously rotate under the action of the reverse force of the water flow, thereby evenly spraying the water flow to a larger area and enhancing the spraying effect; the rotatable spray head can spray water from different angles so that the water flow is evenly distributed in the cleaning area, avoiding the problem of local over-cleaning or insufficient cleaning.

[0064] In some embodiments of the present application, the water pipe 10 includes a first water pipe 11 and a second water pipe 12, each of which is configured for plug-in assembly. A plug-in portion 111 is provided at the end of the first water pipe 11, and a plug-in sleeve 121 is provided at the end of the second water pipe 12, which is sleeved outside the plug-in portion 111. The plug-in portion 111 is provided with a plurality of clips 112 extending radially outward, and the plug-in sleeve 121 is provided with a plurality of latching holes 122 that match the clips 112. The plug-in assembly method of the water pipe 10 makes the connection between the first water pipe 11 and the second water pipe 12 very simple. Simply insert the plug-in portion 111 of the first water pipe 11 into the plug-in sleeve 121 of the second water pipe 12, and the clips 112 will automatically snap into the latching holes 122, completing the connection. When the dishwasher is operating, the water pipe 10 must withstand a certain amount of water pressure and water flow impact. This stable connection ensures that the water pipe will not loosen or fall off, thereby ensuring the normal operation of the dishwasher. The cooperation between the plug-in portion 111 and the plug-in sleeve 112 can form a good seal to prevent water leakage.

[0065] In some embodiments of the present application, the plug sleeve 12 is provided with a plurality of partitions 123 communicating with the ends thereof; the partitions 123 are arranged axially, and the locking hole 122 is located between two of the partitions 123. The insertion of the plug portion 111 of the first water pipe 11 into the plug sleeve 121 of the second water pipe 12 can be achieved by radially outward deformation of the sleeve wall of the plug sleeve 12; the locking hole 122 is passed through the radial cross-section of the end of the partitions 123 on the plug sleeve 121. The provision of the partitions 123 gives the sleeve wall of the plug sleeve 121 a certain elastic deformation capability. When the plug portion 111 of the first water pipe 11 is inserted into the plug sleeve 121 of the second water pipe 12, the sleeve wall of the plug sleeve 121 can adapt to the size of the plug portion 111 by radially outward deformation, thereby making the insertion process smoother. The card hole 122 is located between the two partition openings 123. When the plug-in part 111 is inserted into the plug sleeve 121, the buckle 112 can be accurately snapped into the card hole 122. The existence of the partition opening makes the sleeve wall around the card hole 122 have a certain elasticity, which can better fix the buckle 112 and prevent it from loosening or falling off.

[0066] In some embodiments of the present application, the second water pipe 12 comprises a second body 120, a connecting rim 124 extending radially outward from one end of the second body 120, and a plug sleeve 121 extending radially along the outer ring of the connecting rim 124. A sealing ring 13 is provided between the plug portion 111 and the connecting rim 124. The sealing ring 13 ensures a reliable seal at the connection between the first and second water pipes 11 and 12. The sealing ring 13 between the plug portion 111 and the connecting rim 124 prevents water from leaking from the connection. During installation, the sealing ring 13 is simply placed between the plug portion 111 and the connecting rim 124, and then the plug portion 111 is inserted into the plug sleeve. The sealing ring automatically fills the gap, forming a seal, eliminating the need for complex sealing processes.
