[0045] The objectives, features, and advantages of this invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0047] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0048] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0049] Existing dishwashers typically include a housing, a water hose assembly, a spray arm assembly, and a dish rack assembly. The water hose assembly includes an inner water hose and a water hose connector, with the connector connecting to the outlet of the inner water hose. The spray arm assembly includes an upper spray arm, a middle spray arm, and a lower spray arm, arranged sequentially from top to bottom within the housing. Both the upper and lower spray arms are connected to the inner water hose, and the middle spray arm is connected to the inner water hose via the water hose connector. The dish rack assembly includes an upper dish rack and a lower dish rack, which are detachably mounted within the housing so that they can be removed. The upper dish rack is positioned above the lower dish rack, and the middle spray arm is positioned between the upper and lower dish racks and connected to the upper dish rack for fixation. The middle spray arm typically sprays water upwards to clean the dishes in the upper dish rack.

[0050] Therefore, it is evident that existing dishwashers typically require the spray arm to be fixed to the upper rack for proper operation. Current dishwashers do not allow the upper rack to be removed before operation, as this would prevent the spray arm from being secured and cause the dishwasher to malfunction. Furthermore, because the upper rack occupies a significant amount of space within the dishwasher, its inability to be removed prevents the placement of large tableware such as large pots and pans, thus limiting the dishwasher's applicability to large items.

[0051] The present invention provides a spray assembly and a dishwasher including the spray assembly, which can solve the problem that existing dishwashers cannot clean large tableware.

[0052] Please see Figures 1 to 4In one embodiment of the spray assembly 10 of the present invention, the spray assembly 10 is applied to a dishwasher, the dishwasher including an inner water pipe 300 and a water pipe connector 400 disposed on the inner water pipe 300. The spray assembly 10 includes a nozzle body 100 and a locking member 200. The nozzle body 100 is provided with a connector 111, the connector 111 being inserted into and connected to the water pipe connector 400. The locking member 200 is movably disposed on the nozzle body 100, and the locking member 200 has a first engaging position and a second engaging position that engages with the nozzle body 100. In the first engaging position, the locking member 200 locks the nozzle body 100 to the water pipe connector 400. In the second engaging position, the locking member 200 releases the locking of the nozzle body 100, so that the nozzle body 100 can be separated from the water pipe connector 400 (e.g., ...). Figures 10 to 13 (As shown).

[0053] It is understandable that the connector 111 is inserted into the water pipe connector 400. Either the connector 111 is inserted into the water pipe connector 400, or the water pipe connector 400 is inserted into the connector 111; the specific arrangement is not limited here. The nozzle body 100 is provided with spray holes 125, which are connected to the inner water pipe 300 via the water pipe connector 400, allowing the spray holes 125 to spray water outwards.

[0054] Furthermore, the locking member 200 has a first engaging position and a second engaging position that engage with the nozzle body 100. The locking member 200 can be engaged with the nozzle body 100, or the nozzle body 100 can be engaged with the locking member 200; the specific engagement is not limited here. For example, the locking member 200 may have a buckle, and the nozzle body 100 may have a buckle groove; the buckle of the locking member 200 engages with the buckle groove on the nozzle body 100. Alternatively, the locking member 200 may have a buckle groove, and the nozzle body 100 may have a buckle; the buckle of the nozzle body 100 engages with the buckle groove on the locking member 200.

[0055] The locking member 200 moves on the nozzle body 100, allowing it to have a first engaging position and a second engaging position. In the first engaging position, the locking member 200 acts as a limit, securing the nozzle body 100 to the water pipe connector 400, meaning the spray assembly 10 is installed on the water pipe connector 400. In the second engaging position, the locking member 200 releases the limit on either the nozzle body 100 or the water pipe connector 400, allowing the nozzle body 100 to separate from the water pipe connector 400, meaning the spray assembly 10 can be detached from the water pipe connector 400. This design simplifies the assembly and disassembly of the spray assembly 10 and the water pipe connector 400, making it easy to operate and improving the efficiency of installation and disassembly of the spray assembly 10.

[0056] The spray assembly 10 of this application includes a nozzle body 100 and a locking member 200. The nozzle body 100 is provided with a connector 111, which is inserted and connected to a water pipe connector 400. The locking member 200 is movably disposed on the nozzle body 100 and has a first engagement position and a second engagement position for engaging with the nozzle body 100. In the first engagement position, the locking member 200 locks the nozzle body 100 to the water pipe connector 400. In the second engagement position, the locking member 200 releases the lock on the nozzle body 100 so that the nozzle body 100 can be separated from the water pipe connector 400. This arrangement makes it easy to fix or separate the nozzle body 100 from the water pipe connector 400, thereby making it easy to assemble and disassemble the spray assembly 10 with the water pipe connector 400. Furthermore, the way the locking member 200 is engaged with the nozzle body 100 simplifies the structure of the spray assembly 10. When the dishwasher needs to clean large tableware 11, the upper rack of the dishwasher can be removed and the middle spray arm of the dishwasher can be disassembled. The spray assembly 10 of this application can be installed on the water pipe connector 400 of the dishwasher to replace the middle spray arm. This allows the dishwasher to still operate normally after the upper rack is removed, and the dishwasher with the upper rack removed can accommodate large tableware 11 inside the dishwasher so that the dishwasher can clean large tableware 11, thus improving the applicability of the dishwasher.

[0057] Please see Figures 3 to 6 In one embodiment, the locking member 200 is sleeved on the nozzle body 100, the locking member 200 is provided with a fastening part 210, and the nozzle body 100 is provided with a first mating part 130 and a second mating part 140 spaced apart along the axial direction of the locking member 200; in the first fastening position, the fastening part 210 is fastened with the first mating part 130; in the second fastening position, the fastening part 210 is fastened with the second mating part 140.

[0058] It is understood that the first mating part 130 and the second mating part 140 are spaced apart on the nozzle body 100 along the axial direction of the locking member 200, that is, the locking member 200 is movably disposed on the nozzle body 100 along its axial direction, so that the locking member 200 has a first engaging position and a second engaging position. The locking member 200 has a hollow structure and is open at both ends. The locking member 200 can be retractably disposed on the nozzle body 100; or, the locking member 200 can be slidably disposed on the nozzle body 100; or, the locking member 200 can be rotatably disposed on the nozzle body 100. That is, the way the locking member 200 moves is not limited, as long as the locking member 200 can change its position in its axial direction and ensures that the engaging part 210 can engage with the first mating part 130 or the second engaging part 210.

[0059] The fastening part 210 can be a snap-fit ​​or a latching platform; the specific type is not limited here. Correspondingly, the first mating part 130 and / or the second mating part 140 can be a latching groove or a latching hole 114. The structure of the fastening part 210, the first mating part 130, and the second mating part 140 can be set as needed and is not limited here. By setting the fastening part 210, the first mating part 130, and the second mating part 140, the fastening connection between the locking member 200 and the nozzle body 100 is simplified, which helps to simplify the structure of the spray assembly 10 and improve the assembly and disassembly efficiency of the spray assembly 10.

[0060] Please see Figure 4 , Figure 10 and Figure 12 In one embodiment, the fastening part 210 includes an elastic buckle 211, the first mating part 130 includes a first fastening position 131, and the second mating part 140 includes a second fastening position 141. The elastic buckle 211 can be fastened to the first fastening position 131 or the second fastening position 141 by movement.

[0061] It is understood that the first latch 131 and / or the second latch 141 can be a latch groove, or of course, a latch hole 114; the specific type is not limited here. The elastic buckle 211 is elastic, making it easy to latch into the first latch 131 or the second latch 141. Under the push of an external force, the elastic buckle 211 deforms and easily disengages from the first latch 131 or the second latch 141, thereby allowing the locking member 200 to smoothly switch between the first latching position and the second latching position, thus improving the smoothness of the movement of the locking member 200.

[0062] Please see Figure 4 , Figure 6 and Figure 7 In one embodiment, the locking member 200 includes a locking sleeve 220, which is sleeved on the nozzle body 100. The elastic buckle 211 is located at the end of the locking sleeve 220 away from the water pipe connector 400. One of the locking sleeve 220 and the nozzle body 100 is provided with a guide strip 150, and the other is provided with a guide groove 221. The guide strip 150 is slidably disposed in the guide groove 221 along the length direction of the guide groove 221. The length direction of the guide groove 221 is consistent with the direction of the first buckle 131 toward the second buckle 141.

[0063] Understandably, by setting the guide bar 150 and guide groove 221, the locking member 200 can move smoothly on the nozzle body 100, avoiding any misalignment of the locking member 200. Furthermore, the length direction of the guide groove 221 is consistent with the direction from the first latch 131 to the second latch 141, ensuring that the locking member 200 is accurately positioned at the first and second latching positions when moving along the guide bar 150. This ensures the accuracy of the locking member 200's movement and improves the stability of the spray assembly 10. In this embodiment, the guide strip 150 is arranged along the axial direction of the locking sleeve 220, and the first latch 131 is also arranged along the axial direction of the locking sleeve 220 in the direction of the second latch 141. That is, when the locking sleeve 220 moves along its axial direction, it has a first latching position and a second latching position. This is beneficial to shorten the distance that the locking member 200 moves, thereby making the structure of the locking member 200 and the nozzle body 100 compact, which is beneficial to reduce the volume of the nozzle body 100 and reduce production costs.

[0064] Please see Figure 3 , Figure 4 and Figure 6 In one embodiment, the locking member 200 further includes a gripping portion 230, which is disposed on the outer side wall of the locking sleeve 220, and a gripping space is formed between the gripping portion 230 and the locking sleeve 220. Specifically, in this embodiment, the gripping portion 230 is arranged in a ring shape and is sleeved on the locking sleeve 220. The gripping space formed between the gripping portion 230 and the locking sleeve 220 facilitates the application of external force to the locking member 200 by extending a hand into the gripping space, thereby facilitating the assembly and disassembly of the spray assembly 10 and improving the assembly efficiency of the spray assembly 10.

[0065] Please see Figures 6 to 8 as well as Figure 10 and Figure 12 In one embodiment, the connector 111 is hollow and has a limiting part 112 that is movable radially thereon. In the first engagement position, the locking member 200 locks the limiting part 112, which is fixed to the water pipe connector 400. In the second engagement position, the locking member 200 releases the locking of the limiting part 112, and the limiting part 112 removes the limitation on the position of the water pipe connector 400, so that the water pipe connector 400 can be separated from the nozzle body 100.

[0066] It is understandable that the specific structure of the limiting part 112 is not limited, as long as the nozzle body 100 can be connected and fixed or separated from the water pipe connector 400. By providing the limiting part 112 on the connector 111, the nozzle body 100 itself can limit and fix the water pipe connector 400 without the need to add additional limiting parts to limit and fix the water pipe connector 400, which helps to simplify the structure of the spray assembly 10.

[0067] Furthermore, the locking member 200 is sleeved on the nozzle body 100, and the locking member 200 is movably disposed on the nozzle body 100 along its axis. The limiting part 112 is movably disposed on the connector 111 along the radial direction of the connector 111. When the locking member 200 moves to the first engaging position, it locks the limiting part 112. The limiting part 112 moves radially along the connector 111 to limit the water pipe connector 400, thus fixing the connector 111 onto the water pipe connector 400. When the locking member 200 moves to the second engaging position, it releases the locking of the limiting part 112. The limiting part 112 moves radially along the connector 111 to separate from the water pipe connector 400, thus removing the limiting effect of the limiting part 112 on the water pipe connector 400. At this point, the water pipe connector 400 can separate from the connector 111, allowing the nozzle body 100 to separate from the water pipe connector 400. This arrangement simplifies the limiting effect of the limiting part 112 on the connector 111 on the water pipe connector 400 and the method of removing the limiting effect, which helps to simplify the structure of the spray assembly 10.

[0068] Please see Figure 7 , Figure 10 and Figure 12 In one embodiment, the limiting part 112 includes a limiting snap 113, and the water pipe connector 400 is provided with a limiting groove 421; in the first fastening position, the limiting snap 113 is fastened in the limiting groove 421 to limit the position of the limiting groove 421; in the second fastening position, the limiting snap 113 moves out of the limiting groove 421 to cancel the limitation on the position of the limiting groove 421.

[0069] It is understandable that the shape of the limiting groove 421 is not limited, as long as it is compatible with the structure of the limiting spring 113. When the locking member 200 moves to the first engaging position, the limiting spring 113 engages within the limiting groove 421, thus connecting and fixing the nozzle body 100 to the water pipe connector 400. When the locking member 200 moves to the second engaging position, the limiting spring 113 is no longer locked by the locking member 200, and the limiting spring 113 springs back and moves out of the limiting groove 421. The limiting spring 113 cancels the limiting of the water pipe connector 400, thereby allowing the water pipe connector 400 to separate from the connector 111. Therefore, by setting the limiting spring 113 and the limiting groove 421, the method of limiting and fixing the nozzle body 100 to the water pipe connector 400 is simple, which helps to simplify the structure of the spray assembly 10 and facilitates the assembly and disassembly of the spray assembly 10.

[0070] Please see Figures 10 to 13 In one embodiment, the locking member 200 is sleeved on the connector 111 and can move back and forth along the axial direction of the connector 111. The locking member 200 is provided with a locking part 222. In the first engagement position, the locking part 222 presses the limiting spring buckle 113 to keep the limiting spring buckle 113 within the limiting groove 421. In the second engagement position, the locking part 222 avoids the limiting spring buckle 113, and the limiting spring buckle 113 springs back out from the limiting groove 421.

[0071] Understandably, the limiting spring clip 113 is elastic. When the locking member 200 is in the first engaged position, the locking part 222 presses against the limiting spring clip 113, so that the limiting spring clip 113 can be locked within the limiting groove 421. This ensures the stability of the connection and fixation between the nozzle body 100 and the water pipe structure. When the locking member 200 is in the second engaged position, the locking member 200 avoids the limiting spring clip 113, and the limiting spring clip 113 is no longer subjected to the pressing force of the locking part 222, so it can spring back and move out of the limiting groove 421. At this time, the nozzle body 100 can be separated from the water pipe connector 400. As can be seen, by pressing and avoiding the limiting spring 113, the locking part 222 achieves the limiting and unlocking of the limiting part 112. The locking part 222 achieves the limiting and unlocking in a simple way, which helps to simplify the structure of the spray assembly 10, and also facilitates the assembly and disassembly of the spray assembly 10.

[0072] In one embodiment, there are multiple limiting spring clips 113, which are arranged sequentially at intervals around the circumference of the connector 111. The number of limiting grooves 421 corresponds to the number of limiting spring clips 113. This ensures that the limiting spring clips 113 are evenly distributed on the outer peripheral wall of the connector 111, which helps to improve the stability of the spray assembly 10 installed on the water pipe connector 400.

[0073] Please see Figures 7 to 9 In one embodiment, the side wall of the connector 111 is provided with a buckle hole 114, and the limiting spring buckle 113 is disposed in the buckle hole 114 along the axial direction of the connector 111. The limiting spring buckle 113 includes a support part 1131 and a buckle part 1132. The support part 1131 has a connecting end and a free end disposed opposite to each other. The connecting end of the support part 1131 is connected to the side wall of the buckle hole 114, and the buckle part 1132 is disposed at the free end of the support part 1131 and located inside the support part 1131.

[0074] It is understandable that the free end of the support part 1131 is spaced apart from the wall of the buckle hole 114 so that the free end of the support part 1131 can move radially along the connector 111. The buckle part 1132 is located inside the support part 1131 so that when the locking member 200 is pressed on the support part 1131, the buckle part 1132 can extend into the limiting groove 421 to limit the position of the limiting groove 421, that is, to limit the water pipe connector 400.

[0075] In this embodiment, the support portion 1131 is arranged along the axial direction of the connector 111, and the free end of the support portion 1131 is located between the connecting end of the support portion 1131 and the water pipe connector 400. That is, the free end of the support portion 1131 is arranged close to the water pipe connector 400. This helps to shorten the distance between the buckle portion 1132 and the water pipe connector 400, thereby helping to reduce the height of the nozzle body 100, and further helping to reduce the volume of the spray assembly 10 and reduce production costs.

[0076] In one embodiment, the top surface of the buckle 1132, away from the support 1131, is located inside the inner wall of the connector 111. This arrangement is equivalent to the buckle 1132 protruding from the inner wall of the connector 111. When the locking part 222 presses against the support 1131, the free end of the support 1131 can be confined within the limiting groove 421 after a short movement. This improves the stability of the limiting spring buckle 113 engaging within the limiting groove 421, thereby enhancing the stability of the spray assembly 10 installed on the water pipe connector 400.

[0077] In one embodiment, the latch 1132 has guide surfaces 1133 at both opposite ends along the axial direction of the connector 111. These guide surfaces 1133 guide the movement of the water pipe connector 400. It is understood that when the water pipe connector 400 is inserted into the cavity of the connector 111, the guide surface 1133 of the latch 1132 away from the connecting end of the support 1131 guides the insertion of the water pipe connector 400, improving the smoothness of insertion. When the water pipe connector 400 is removed from the connector 111, the guide surface 1133 of the latch 1132 near the connecting end of the support 1131 guides the removal of the water pipe connector 400, improving the smoothness of removal from the cavity of the connector 111. Therefore, by providing guide surfaces 1133 on the latch 1132, the assembly and disassembly efficiency of the nozzle body 100 and the water pipe connector 400 is improved.

[0078] Please see Figures 7 to 9 In one embodiment, the limiting spring buckle 113 further includes a protrusion 1134, which is disposed at the free end of the support portion 1131 and located on the outside of the support portion 1131. The top surface of the protrusion 1134 away from the support portion 1131 is located on the outside of the outer wall surface of the connector 111.

[0079] It is understandable that the top surface of the protrusion 1134 away from the support 1131 is located on the outer side of the outer wall of the connector 111, that is, the limiting spring buckle 113 protrudes from the outer surface of the connector 111. When the locking member 200 is sleeved on the connector 111 of the nozzle body 100 and is in the first fastening position, the locking part 222 of the locking member 200 can press the protrusion 1134, causing the limiting spring buckle 113 to deform. The buckle part 1132 of the limiting spring buckle 113 can extend into the limiting groove 421, thus ensuring the stability of the connection and fixation between the nozzle body 100 and the water pipe structure. By providing the protrusion 1134, the limiting spring buckle 113 is easily deformed and extends into the limiting groove 421. The protrusion 1134 is located on the outside of the support part 1131, making the limiting spring buckle 113 easy to process. The locking part 222 of the locking member 200 is also easy to process. In this embodiment, the locking part 222 of the locking member 200 is cylindrical.

[0080] Furthermore, the height of the protrusion 1134 protruding from the outer surface of the support portion 1131 gradually decreases from the free end of the support portion 1131 toward the connecting end of the support portion 1131. This arrangement creates a guide slope on the outer surface of the protrusion 1134, which guides the movement of the locking member 200, thereby improving the smoothness of the switching between the first and second engaging positions of the locking member 200.

[0081] Please see Figure 4 , Figure 5 and Figure 11 In one embodiment, the water pipe connector 400 includes a connector body 410 and a plug connector 420 disposed on one side of the connector body 410. The plug connector 420 is inserted into the inner cavity of the connector 111. The outer peripheral wall of the plug connector 420 is provided with a limiting groove 421 arranged in an annular shape. In the first fastening position, the limiting snap 113 is fastened in the limiting groove 421 and can rotate around the outer peripheral wall of the plug connector 420.

[0082] Understandably, the connector 420 is hollow, allowing it to communicate with the connector 111. When the connector 420 is inserted into the connector 111, and the locking member 200 is in the first engaged position, the limiting spring 113 engages within the limiting groove 421. Because the limiting groove 421 is annular, the limiting spring 113 can rotate around the outer peripheral wall of the connector 420, thereby allowing the nozzle body 100 to rotate around the outer peripheral wall of the connector 420. In other words, the spray assembly 10 is rotatably mounted on the water pipe connector 400. The rotation of the spray assembly 10 increases the spray distance and intensity, thus increasing the spray area and intensity, which helps improve the cleanliness of the dishwasher's dishes.

[0083] In one embodiment, the dishwasher further includes a sealing ring 500, which is fitted onto the connector 420 and located within the limiting groove 421. The sealing ring 500 is used to seal the gap between the connector 420 and the mating connector 111. It is understood that by providing the sealing ring 500, water will not leak from the gap between the connector 420 and the mating connector 111 when the water pipe connector 400 is connected to the mating connector 111 of the spray assembly 10, improving the sealing performance of the connection between the spray assembly 10 and the water pipe connector 400, thereby improving the reliability of the dishwasher.

[0084] Please see Figure 6 and Figure 10 In one embodiment, the nozzle body 100 includes an adapter plug 110 and a spray head 120. The connector 111 is located at the end of the adapter plug 110 away from the spray head 120, and the spray head 120 is inserted into the adapter plug 110. It is understood that the adapter plug 110 has a hollow structure and is open at both ends. By providing the adapter plug 110, the nozzle body 100 can be easily connected to the water pipe connector 400. The spray head 120 is inserted into the adapter plug 110; alternatively, the spray head 120 can be inserted into the adapter plug 110, or the adapter plug 110 can be inserted into the spray head 120. This is not limited here. This arrangement simplifies the connection and fixing method, thereby making the structure of the nozzle body 100 simple and easy to manufacture.

[0085] Please see Figure 10 and Figure 13 In one embodiment, the spray head 120 includes a spray body 121 and a connector 122 communicating with the spray body 121. The connector 122 is inserted into the adapter plug 110. A positioning boss 123 is provided on the side wall of the connector 122, and a positioning through hole 115 is provided on the side wall of the adapter plug 110. The positioning boss 123 is inserted into the positioning through hole 115. It is understood that the positioning boss 123 is located on the outer peripheral wall of the connector 122, and the positioning through hole 115 is located at the end of the adapter plug 110 near the spray head 120. The positioning boss 123 being inserted into the positioning through hole 115 allows the spray head 120 to be quickly installed onto the adapter plug 110.

[0086] In addition, there can be multiple positioning protrusions 123. Multiple positioning protrusions 123 are arranged sequentially at intervals around the circumference of the plug 122. Multiple positioning through holes 115 are provided on the adapter plug 110. Multiple positioning protrusions 123 are arranged one-to-one with multiple positioning through holes 115. This arrangement helps to improve the stability of the spray head 120 installed on the adapter plug 110.

[0087] Please see Figure 11 and Figure 13 In one embodiment, the positioning through hole 115 is the first buckle 131, and at the first buckling position, the elastic buckle 211 is fastened in the positioning through hole 115. It is understandable that the adapter plug 110 has a hollow structure with open ends. The plug portion 122 of the spray head 120 is inserted into the inner cavity of the adapter plug 110, and the positioning boss 123 of the plug portion 122 is inserted into the positioning through hole 115. Furthermore, the locking member 200 is sleeved on the adapter plug 110. When the locking member 200 is in the first engagement position, the elastic buckle 211 of the locking member 200 engages in the positioning through hole 115. That is, the positioning through hole 115 can accommodate the positioning boss 123 of the plug portion 122 and the elastic buckle 211 of the locking member 200. This helps to improve the utilization rate of the positioning through hole 115, which in turn improves the space utilization rate of the adapter plug 110. This makes the plug portion 122 and the elastic buckle 211 on the adapter plug 110 arranged in a compact manner, thereby helping to reduce the production cost of the adapter plug 110.

[0088] In one embodiment, the spray head 120 is inserted into the adapter plug 110, with a first locking position 131 on the adapter plug 110 and a second locking position 141 on the spray head 120. This allows the first locking position 131 and the second locking position 141 to maintain a certain distance, providing movement space for the locking member 200, thereby achieving locking and unlocking of the spray head body 100. At the same time, it avoids the first locking position 131 and the second locking position 141 being located on the same structure, which would affect the structural strength of the parts. This ensures the structural strength of the adapter plug 110 and the spray head 120, thereby improving the reliability of the spray assembly 10.

[0089] Please see Figures 1 to 4 The present invention also proposes a dishwasher, which includes an inner water pipe 300, a water pipe connector 400, and a spray assembly 10 as described above. The water pipe connector 400 is connected to the water outlet end of the inner water pipe 300. The spray assembly 10 is provided with a connector 111, which is inserted and connected to the water pipe connector 400. The specific structure of the spray assembly 10 is as described in the above embodiments. Since the dishwasher adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0090] Understandably, the water pipe connector 400 is detachably and washably installed on the inner water pipe 300. Water flowing out from the outlet of the inner water pipe 300 can enter the spray assembly 10 after passing through the water pipe connector 400, so that the spray assembly 10 can spray water outward.

[0091] In one embodiment, the water pipe connector 400 is located in the middle of the inner water pipe 300, and the nozzle body 100 of the spray assembly 10 is provided with a spray hole 125 at one end away from the water pipe connector 400. The spray hole 125 is used to spray water in a direction away from the inner water pipe 300.

[0092] Understandably, the inner water pipe 300 has water outlets at both ends and in the middle. The dishwasher also includes an upper spray arm and a lower spray arm. The upper spray arm is connected to the upper water outlet of the inner water pipe 300 and is used to spray water downwards. The lower spray arm is connected to the lower water outlet of the inner water pipe 300 and is used to spray water upwards. The spray assembly 10 is located in the middle of the inner water pipe 300. The end of the spray assembly 10 facing away from the inner water pipe 300 has a spray hole 125 so that the spray hole 125 can spray water in the direction away from the inner water pipe 300, that is, the spray hole 125 can spray water in front of the middle of the inner water pipe 300.

[0093] Furthermore, in this embodiment, the dishwasher does not have an upper rack; it only has a lower rack. This results in a larger internal space, allowing large tableware 11, such as pots and pans or baking trays, to be placed on the lower rack and cleaned by the spray assembly 10. Therefore, compared to existing dishwashers, the dishwasher of this application can clean both large and small tableware, making it highly versatile.

[0094] In one embodiment, the dishwasher further includes a housing 600, the housing 600 having a loading / unloading port 610, the spray assembly 10 being disposed inside the housing 600, the nozzle body 100 having a water outlet 124, the spray holes 125 being disposed on the water outlet 124, and the outer surface of the water outlet 124 facing the loading / unloading port 610.

[0095] It is understood that the outer casing 600 includes a back panel, which is positioned opposite to the loading / unloading port 610. Tableware can be placed into or removed from the outer casing 600 through the loading / unloading port 610. An inner water pipe 300 is mounted on the back panel. The spray assembly 10 is mounted on the inner water pipe 300 via a water pipe connector 400. The spray assembly 10 includes a nozzle body 100, which has a connector 111 that is inserted into the water pipe connector 400. The outer surface of the water outlet portion 124 of the nozzle body 100 faces the loading / unloading port 610. A switch door can be installed at the loading / unloading port 610, meaning the outer surface of the water outlet portion 124 of the nozzle body 100 can face the switch door or face one side of the switch door. The water outlet portion 124 has multiple spray holes 125, allowing multiple spray holes 125 to spray water towards the switch door and one side thereof. It should be noted that the direction of the opening and closing door and one side includes not only the direction of the spray hole 125 toward the opening and closing door (from the back panel toward the loading and unloading port 610), but also the upper, lower, left, and right sides of the opening and closing door. The spray area of ​​the spray hole 125 of the spray assembly 10 of this application is relatively large, which is beneficial to improving the cleanliness of the dishwasher when cleaning large tableware 11.

[0096] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
