[0043] The following reference Figures 1 to 9 The present application describes a combined dishwasher spray arm according to an embodiment.

[0044] See Figures 1 to 9 As shown, an embodiment of this application provides a combined dishwasher spray arm. This combined dishwasher spray arm includes a main spray arm 1, a reinforcing spray arm 2, and a fixing component 3. The main spray arm 1 is provided with a mounting port 102, and the fixing component 3 is detachably disposed at the mounting port 102. The reinforcing spray arm 2 is disposed at the mounting port 102 via the fixing component 3, and the reinforcing spray arm 2 is rotatable relative to the main spray arm 1. Preferably, the volume of the reinforcing spray arm 2 is smaller than the volume of the main spray arm 1. The main spray arm 1 can rinse most areas, while the reinforcing spray arm 2 can assist in rinsing areas that the main spray arm 1 cannot cover, thereby improving the washing capacity of this combined dishwasher spray arm and enhancing the washing effect of the dishwasher.

[0045] The main spray arm 1 has a first cavity for the flow of washing water, and the reinforcing spray arm 2 has a second cavity. The second cavity is sequentially connected to the fixing component 3 and the first cavity, so that the washing water flowing into the first cavity can flow into the second cavity. The washing water flowing into the second cavity can be used to meet the washing needs of the reinforcing spray arm 2, and can also serve as the driving force to drive the reinforcing spray arm 2 to rotate. This allows the main spray arm 1 to rotate and spray to clean the dishes or other items in the dishwasher, while the reinforcing spray arm 2 can follow the rotation of the main spray arm 1 and work together with the main spray arm 1 to perform the cleaning task of the dishes or other items, thereby achieving a stronger washing effect. Compared with the traditional single spray arm mode, it expands the cleaning range, effectively reduces or avoids the generation of washing dead corners, and significantly improves the cleaning effect of the dishwasher using this combination dishwasher spray arm.

[0046] Specifically, the main spray arm 1 includes multiple first arm forks 101. Preferably, there are three first arm forks 101, which are structurally identical and arranged symmetrically at the center. At least one of the three first arm forks 101 is provided with a mounting port 102. When there is more than one mounting port 102, each mounting port 102 is provided with a fixing component 3 and a reinforcing spray arm 2. Preferably, the reinforcing spray arm 2 is located near the end of the first arm fork 101 away from the center of symmetry. It should be noted that each first arm fork 101 is provided with one reinforcing spray arm 2.

[0047] The main spray arm 1 includes a first upper housing 103 and a first lower housing 104 that are adapted to each other in shape. The first upper housing 103 and the first lower housing 104 can be fastened together to form a first cavity between them. The mounting port 102 is provided on the first upper housing 103. Correspondingly, the reinforcing spray arm 2 is rotatably provided on the first upper housing 103 and located above the main spray arm 1.

[0048] In both the first upper housing 103 and the first lower housing 104, at least the first upper housing 103 is provided with a first drive hole and a first spray hole. The number of the first drive hole and the first spray hole are both multiple. Preferably, the multiple first drive holes and the multiple first spray holes have multiple water outlet directions to ensure the stability of the main spray arm 1 during rotation, and also to ensure the cleaning effect and cleaning range of the main spray arm 1 on the tableware.

[0049] The first upper housing 103 has a first connecting edge 4 on its edge, which is integral with the first upper housing 103 and can be manufactured by stamping. The first connecting edge 4 includes a first flange 401, a bent edge 402 and a second flange 403, which are integrally formed. The first flange 401 and the second flange 403 are connected by the bent edge 402. The first flange 401 and the second flange 403 are arranged facing each other. The second flange 403 is located below the first flange 401. The first flange 401, the bent edge 402 and the second flange 403 form an insertion space.

[0050] The edge of the first lower housing 104 is provided with a second connecting edge 5. The second connecting edge 5 is specifically a sheet-like pressing edge. The second connecting edge 5 and the first lower housing 104 have an integral structure. The second connecting edge 5 can be inserted into the insertion space, so that the first connecting edge 4 can cover the second connecting edge 5 to realize the assembly of the first upper housing 103 and the first lower housing 104. After each first connecting edge 4 and the corresponding second connecting edge 5 are connected in place, the two are riveted so that the first flange 401, the bent edge 402 and the second flange 403 can fit tightly with the pressing edge without gaps, thereby fixing the first upper housing 103 and the first lower housing 104.

[0051] Furthermore, the first upper housing 103 is provided with a plurality of reinforcing protrusions 105, which are spaced apart on the first connecting edge 4. The reinforcing protrusions 105 protrude relative to the outer wall surface of the first upper housing 103. The second connecting edge 5 is provided with a reinforcing connecting edge opposite to each reinforcing protrusion 105. The reinforcing connecting edge has a recessed or grooved structure. During the riveting process after the first upper housing 103 and the first lower housing 104 are assembled, the reinforcing protrusions 105 are subjected to force and transmit the force to the first connecting edge 4, so that the position of the first connecting edge 4 opposite to the reinforcing protrusions 105 protrudes towards the second connecting edge 5 and is embedded in the reinforcing connecting edge. This increases the riveting strength between the first connecting edge 4 and the second connecting edge 5, ensuring the connection strength between the first upper housing 103 and the first lower housing 104 and the stability between them.

[0052] Furthermore, the spray arm 2 is reinforced with multiple second arm forks 201. Preferably, there are three second arm forks 201. The three second arm forks 201 have the same structure and are arranged in a centrally symmetrical manner. A water inlet 204 is provided at the symmetrical center position of the three second arm forks 201, and the water inlet 204 is connected to the fixing component 3.

[0053] The reinforced spray arm 2 includes a second upper housing 202 and a second lower housing 203 that are adapted to each other in shape. The second upper housing 202 and the second lower housing 203 can be interlocked to form a second cavity between them. The water inlet 204 is located at the center of the second lower housing 203.

[0054] In both the second upper housing 202 and the second lower housing 203, at least the second upper housing 202 is provided with a second driving hole and a second spray hole. The number of the second driving hole and the second spray hole are both multiple. Preferably, the multiple second driving holes and the multiple second spray holes have multiple water outlet directions to ensure the stability of the enhanced spray arm 2 during rotation, and also to ensure the enhanced cleaning effect and cleaning range of the spray arm 2 on the tableware.

[0055] Similarly, the edge of the second upper housing 202 is provided with a third connecting edge, and the edge of the second lower housing 203 is provided with a fourth connecting edge. The third connecting edge and the fourth connecting edge are connected to each other to complete the connection and fixation of the second upper housing 202 and the second lower housing 203. The specific connection structure and connection method between the third connecting edge and the fourth connecting edge can be referred to the above description of the connection between the first connecting edge 4 and the second connecting edge 5. Those skilled in the art can fully understand this, and it will not be elaborated further.

[0056] Furthermore, the first upper shell 103, the first lower shell 104, the second upper shell 202, and the second lower shell 203 are all made of stainless steel. The outer surfaces of the first upper shell 103, the first lower shell 104, the second upper shell 202, and the second lower shell 203 all have a mirror finish, making them more refined and aesthetically pleasing, and they also have better corrosion resistance.

[0057] Further, the fixing component 3 includes a first fixing member 301 and a second fixing member 302. The first fixing member 301 includes a first connecting body 3011, which is provided with a first connecting part 3012. The first connecting part 3012 is connected to the water inlet 204 of the reinforcing spray arm 2. The inner wall surface of the water inlet 204 is provided with an internal thread, and the first connecting part 3012 is provided with an external thread that matches the internal thread of the water inlet 204. The first connecting part 3012 and the water inlet 204 can be connected by a threaded connection. The first connecting body 3011 is provided with a first communicating channel. After the first connecting body 3011 is connected to the water inlet 204, the first communicating channel communicates with the water inlet 204 and the second cavity. The first connecting body 3011 is provided with an operating part 3013 in a circumferential direction. The operating part 3013 is in the shape of a sheet or plate. Preferably, the operating part 3013 and the first connecting body 3011 have an integral structure. The operating part 3013 has multiple operating edges, which are connected end to end, so that the edge shape of the operating part 3013 is non-circular, which facilitates the assembly of the first fixing member 301.

[0058] The first fixing member 301 also includes a snap-fit ​​portion 3014. Preferably, there are at least two snap-fit ​​portions 3014, and all snap-fit ​​portions 3014 are evenly spaced. The snap-fit ​​portions 3014 can be disposed on the first connecting body 3011 or the operating part 3013. In this embodiment, the snap-fit ​​portion 3014 is disposed on the side surface of the operating part 3013 facing the main spray arm 1. The snap-fit ​​portion 3014 is partially bent to form a bent portion, such that the end of the snap-fit ​​portion 3014 away from the operating part 3013 bends towards and approaches the first connecting body 3011.

[0059] The second fastener 302 includes a second connecting body 3021, the second connecting body 3021 is provided with a second connecting part 3025, the second connecting part 3025 is connected to the mounting port 102, the edge of the mounting port 102 is recessed towards the inside of the first cavity to form a recessed platform, the second connecting part 3025 can be inserted into the recessed platform and connected to the recessed platform, the connection method between the second connecting part 3025 and the recessed platform is preferably a threaded connection.

[0060] The end of the second connecting body 3021 away from the second connecting part 3025 forms a plug-in part 3022. The diameter of the plug-in part 3022 is smaller than the inner diameter of the first connecting body 3011. When the second fixing member 302 is assembled and connected with the first fixing member 301, the plug-in part 3022 can be plugged into the first connecting body 3011, thereby reducing the overall height of the fixing component 3. This helps to reduce the overall height of the reinforced spray arm 2 after it is assembled with the main spray arm 1, and avoids interference between the reinforced spray arm 2 and other shelves, dish racks, etc. during the washing and rotating rinsing process.

[0061] A fixing part 3023 is provided at one end of the second connecting body 3021 near the reinforcing spray arm 2. The fixing part 3023 is in the form of a sheet or plate and is arranged along the circumference of the second connecting body 3021. Preferably, the fixing part 3023 and the second connecting body 3021 have an integral structure. The outer edge of the fixing part 3023 is circular. The bent part of each snap-fit ​​part 3014 can be snapped into the fixing part 3023, thereby snapping the first fixing member 301 and the second fixing member 302 into each other. Under the impact of the washing water, the first fixing member 301 can rotate relative to the second fixing member 302. Since the edge of the fixing part 3023 is circular, it is beneficial to strengthen the rotation of the spray arm 2 and reduce the rotation resistance.

[0062] A gap is formed between the fixing part 3023 and the second connecting body 3021. When the second connecting body 3021 and the first connecting body 3011 are inserted into each other, the insertion part 3022 can be inserted into the first connecting body 3011, and the height of the end of the first connecting body 3011 near the second connecting body 3021 can be inserted between the fixing part 3023 and the second connecting body 3021. This reduces the overall height of the first fixing member 301 and the second fixing member 302 after assembly, and also helps to reduce pressure loss and water leakage.

[0063] The second connecting body 3021 is also provided with a second connecting channel. After the first fixing member 301 and the second fixing member 302 are assembled, the first cavity, the mounting port 102, the second connecting channel, the first connecting channel, and the water inlet 204 are connected sequentially through the second cavity.

[0064] Furthermore, the operating part 3013 is provided with a first mounting port 3015, which penetrates the upper and lower surfaces of the operating part 3013. The number of first mounting ports 3015 is the same as the number of snap-fit ​​parts 3014 and they are provided in a one-to-one correspondence. Each snap-fit ​​part 3014 has a first mounting port 3015 on its side.

[0065] The fixing part 3023 is provided with a second assembly port 3024. The number of second assembly ports 3024 is the same as the number of first assembly ports 3015. When the first fixing member 301 rotates to a certain position relative to the second fixing member 302, each first assembly port 3015 is positioned opposite a second assembly port 3024, which facilitates the use of tools to pass through the first assembly port 3015 and the second assembly port 3024 to complete the assembly and disassembly of the snap-fit ​​part 3014 and the fixing part 3023.

[0066] Furthermore, the inlet 204 of the reinforced spray arm 2 is partially missing to form a first notch 205, and the first connecting part 3012 is partially missing at the position opposite to the first notch 205 to form a second notch 3016. The first notch 205 and the second notch 3016 are interconnected. After the spray arm of this combined dishwasher stops operating, the residual water inside the reinforced spray arm 2 will gradually gather to the center, then flow back to the main spray arm 1, and finally flow into the bottom of the dishwasher.

[0067] Furthermore, the spray arm of this combined dishwasher also includes a spray arm mounting base 6, which is disposed at the water supply port 106 of the main spray arm 1. The spray arm mounting base 6 is used to connect to the water system of the dishwasher or other designated locations of the dishwasher. The spray arm mounting base 6 includes a mounting base body 601 and a connector 602. The mounting base body 601 is cylindrical in shape, with a hollow interior forming a third connecting channel. The third connecting channel can communicate with the water supply port 106 to supply water to the main spray arm 1.

[0068] The fixed base body 601 has a third connecting part 603 at one end. The third connecting part 603 has an external thread, and the water supply port 106 has an internal thread. The third connecting part 603 and the water supply port 106 are connected by a matching thread.

[0069] The fixing base body 601 also includes a connector 602, specifically a claw. The connector 602 is located on the side of the fixing working body. Preferably, the connector 602 and the fixing base body 601 have an integral structure. A slot is provided at another designated position of the water system or dishwasher for connection with the spray arm fixing base 6. A snap-fit ​​protrusion 6021 is provided at the end of the connector 602 away from the fixing base body 601. The snap-fit ​​protrusion 6021 can be snapped into the slot and move within the slot. It should be noted that in this embodiment, the number of connectors 602 is at least two, and all connectors 602 are equally spaced along the circumference of the fixing base body 601.

[0070] Furthermore, the partial absence of the water inlet 106 forms a third notch 107. When the spray arm of this combination dishwasher stops operating, a small amount of residual water will remain inside the main spray arm 1 and the reinforced spray arm 2. The residual water will gradually gather in the central area of ​​the main spray arm 1 and finally flow back to the bottom of the dishwasher through the third notch 107.

[0071] In summary, the combined dishwasher spray arm provided in this application enables the main spray arm to rotate and spray to clean the dishes or other items inside the dishwasher, while the reinforced spray arm rotates independently following the main spray arm, working together with the main spray arm to perform the cleaning task on the dishes or other items, thereby achieving a stronger washing effect. Compared with the traditional single spray arm mode, it expands the cleaning range, effectively reduces or avoids the generation of washing dead corners, and significantly improves the cleaning effect of the dishwasher using this combined dishwasher spray arm. Furthermore, the connection structure between the main spray arm and the reinforced spray arm adopts a detachable connection method, which facilitates the cleaning and maintenance of this combined dishwasher spray arm and avoids the long-term accumulation of contaminants at the connection position between the main spray arm and the reinforced spray arm.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
