[0057] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0058] Refer to the following Figures 1 to 9 The multifunctional bracket enhanced washing structure and the dishwasher described in the embodiments of the present application are described.

[0059] See also Figures 1 to 9 As shown, an embodiment of the present application provides a multifunctional bracket enhanced washing structure for a dishwasher. The multifunctional bracket enhanced washing structure includes a water supply component 2, a rotating mechanism 4 and a branch water pipe group, wherein the water supply component 2 is arranged on the inner tank 1 of the dishwasher, and the rotating mechanism 4 is also arranged on the inner tank 1 of the dishwasher. The branch water pipe group is fixed to the side wall of the inner tank 1 through the rotating mechanism 4. The branch water pipe group includes a first pipe 6 and a second pipe 7 that can be connected to each other, wherein the first pipe 6 is arranged on the rotating mechanism 4, the first pipe 6 is connected to the water supply component 2, and the second pipe 7 is also arranged on the rotating mechanism 4. Of the first pipe fitting 6 and the second pipe fitting 7, at least the second pipe fitting 7 extends to the interior of the inner tank 1, or the second pipe fitting 7 is entirely located inside the inner tank 1. The cleaning water provided by the water supply component 2 can be supplied to the second pipe fitting 7 through the first pipe fitting 6, so that the second pipe fitting 7 can discharge water to perform local enhanced washing of the tableware or other items inside the inner tank 1. The second pipe fitting 7 can rotate relative to the rotating mechanism 4. When the second pipe fitting 7 rotates, the spray path and spray range of the water discharged from the second pipe fitting 7 change, thereby adjusting the local cleaning coverage of the enhanced washing structure of this multi-functional bracket.

[0060] Specifically, the inner tank 1 includes a top plate, a bottom plate 102, and multiple side plates, one of which is a back plate 101. The water supply component 2 includes a water diversion valve cover 201 and an external connecting pipe 202. The water diversion valve cover 201 is arranged on the outer wall surface of the bottom plate 102 of the inner tank 1. The water diversion valve cover 201 is provided with a water branch port. One end of the external connecting pipe 202 is connected to the water branch port. The water channel branched by the water diversion valve cover 201 flows through the water branch port to the external connecting pipe 202. The other end of the external connecting pipe 202 extends toward the water outlet on the back plate 101 for connection to the water branch pipe group.

[0061] In this embodiment, the wall of the inner tank 1 used to install the water diverter valve cover 201 and the external connecting pipe 202 is partially recessed inward to avoid any change in the depth of the entire machine. In addition, the water diverter valve cover 201 and the external connecting pipe 202 are both located outside the inner tank 1, realizing an external water path, which can reduce the number of internal components of the inner tank 1. The dishwasher's assessment of zero water retention in the inner tank 1 requires not only the dryness of the dishes, but also the degree of water retention in other parts of the inner tank 1. The external water path can reduce the number of components in the inner tank 1, making it more conducive to the machine's zero water retention test. In addition, compared to strengthening the washing water path located in the internal water pipe, the external placement of a separate water pipe can minimize the impact of the new water path on the original water path, reducing the number of tests of the entire machine when changing the water path.

[0062] Furthermore, the back panel 101 of the inner pot 1 is provided with a water outlet. At the location of the water outlet, the inner and outer spaces of the inner pot 1 are connected. A shelf for placing tableware or other items is provided inside the inner pot 1. A shelf fitting 5 is provided near the water outlet, and a part of the shelf fitting 5 is adapted to the water outlet.

[0063] The multifunctional bracket enhanced washing structure also includes a fixing member 3, which is arranged on the inner tank 1. The external connecting pipe 202 and the first pipe 6 are respectively sealed and connected to the fixing member 3 to achieve communication between the external connecting pipe 202 and the first pipe 6. The fixing member 3 includes: a first connecting member 301, a second connecting member 302 and a first sealing member 303. The first sealing member 303 can be specifically a sealing ring, wherein the first connecting member 301 is provided with a convex portion 3011, and the convex portion 3011 is fixed to the first connecting member 301 through secondary injection molding. The convex portion 3011 is made of rubber plastic material and has a certain elasticity. The convex portion 3011 is embedded in the water outlet and abuts against the shelf fitting 5. The shelf fitting 5 is used to form a penetration channel with the part that cooperates with the protrusion 3011. The protrusion 3011 is inserted into the penetration channel. The inner circle diameter of the penetration channel is slightly smaller than the maximum outer circle diameter of the protrusion 3011. When the shelf is located at the deepest part of the inner tank 1, the shelf fitting 5 and the first connecting member 301 produce an interference fit in the water outlet, causing the protrusion 3011 to be radially compressed, thereby forming an axial seal between the protrusion 3011 and the shelf fitting 5, ensuring the sealing effect between the first connecting member 301 and the shelf fitting 5 during operation of the dishwasher.

[0064] The second connecting member 302 has a structure similar to a pipe clamp. The second connecting member 302 is provided with a penetration hole. The end of the external connecting pipe 202 away from the water diversion valve cover 201 is penetrated through the penetration hole and fixed in the first connecting member 301. The second connecting member 302 and the first connecting member 301 are connected by an adaptive thread. The first sealing member 303 is arranged in the second connecting member 302, and when the first connecting member 301 and the second connecting member 302 are in a mutually connected state, the first sealing member 303 is located between the first connecting member 301 and the second connecting member 302. The first sealing member 303 generates compression in the axial direction, thereby forming a radial seal between the first connecting member 301 and the second connecting member 302, ensuring the sealing effect between the first connecting member 301 and the second connecting member 302.

[0065] Preferably, the external connecting pipe 202 in this embodiment is a hose.

[0066] Furthermore, the rotating mechanism 4 is disposed inside the inner container 1. Specifically, the rotating structure is disposed at a position of the shelf near the back plate 101. The rotating mechanism 4 includes a housing, which specifically includes a first fixing seat 401 and a second fixing seat 402. The first fixing seat 401 is provided with a first clamping portion 4011, and the second fixing seat 402 is provided with a second clamping portion 4021. The first clamping portion 4011 and the second clamping portion 4021 can be adapted to be clamped to each other, thereby interlocking and fixing the first fixing seat 401 and the second fixing seat 402. After the first fixing seat 401 and the second fixing seat 402 are interlocked, a receiving cavity is formed between the first fixing seat 401 and the second fixing seat 402. A first notch portion (not shown in the figure due to viewing angle limitations) is provided on one side of the first fixing seat 401. A second notch portion 4022 is formed on the second fixing seat 402 opposite the first notch portion. Both the first and second notches 4022 are arcuate notches, and together they define a first fixing portion in the form of a circular hole, which is used to pass through the first pipe 6. A third notch portion 4012 is formed on a side of the first fixing seat 401 away from the first notch portion. A fourth notch portion 4023 is formed on the second fixing seat 402 opposite the third notch portion 4012. Both the third and fourth notches 4012, 4023 are arcuate notches, and together they define a second fixing portion in the form of a circular hole, which is used to pass through the second pipe 7.

[0067] Furthermore, one end of the first pipe fitting 6 is a first connecting end 601, and the other end of the first pipe fitting 6 is a second connecting end 602. The first connecting end 601 extends toward the water outlet of the inner tank 1 and is passed through the shelf fitting 5 so as to be connected to the external connecting pipe 202. Preferably, a sealing ring is provided between the first connecting end 601 and the shelf fitting 5. After the first pipe fitting 6 is inserted into the shelf fitting 5, the sealing ring can play a sealing role between the two; the second connecting end 602 is arranged at an angle to the first pipe fitting 6, and the second connecting end 602 is provided with a first limiting portion 603. The first limiting portion 603 is distributed along the circumference of the second connecting end 602, and the diameter of the first limiting portion 603 is larger than the outer diameter of the second connecting end 602. The second connecting end 602 is passed through the first fixing portion, and the first limiting portion 603 is located in the accommodating cavity, thereby limiting the second connecting end 602 and the rotating mechanism 4 to prevent the first pipe fitting 6 from separating from the rotating mechanism 4.

[0068] One end of the second pipe fitting 7 is the third connection end 701, and the other end of the second pipe fitting 7 is the water spray outlet 703 of the enhanced washing structure of the multifunctional bracket. A bending portion 702 is formed between the third connection end 701 and the second pipe fitting 7. Since the second pipe fitting 7 is provided with the bending portion 702, the extension direction and extension path of the second pipe fitting 7 are changed, so that when the second pipe fitting 7 rotates along its axial direction with the third connection end 701 as the pivot point, the part of the second pipe fitting 7 located at the bending portion 702 away from the third connection end 701 can rotate with the axis of the third connection end 701 as the rotation center. The second pipe fitting 7 forms a cylindrical motion trajectory during the rotation process, thereby expanding the motion range of the second pipe fitting 7, and then expanding the spray range of the water spray outlet 703, and increasing the enhanced washing coverage of the enhanced washing structure of the multifunctional bracket.

[0069] The third connection end 701 is provided with a second limiting portion 704, which is in the shape of a circular ring. The second limiting portion 704 is distributed along the circumference of the third connection end 701. The diameter of the second limiting portion 704 is larger than the outer diameter of the third connection end 701. The third connection portion is penetrated by the second fixing portion, and the second limiting portion 704 is located in the accommodating cavity, thereby limiting the second pipe fitting 7 and the rotating mechanism 4 to prevent the second pipe fitting 7 from separating or falling off from the rotating mechanism 4.

[0070] The outer surface of the third connecting end 701 is provided with a plurality of elongated limiting ridges 705 . The length of each limiting ridge 705 extends along the axial direction of the second pipe 7 . The plurality of limiting ridges 705 are arranged in parallel at equal intervals. The inner wall surface of the second fixing portion is provided with a plurality of limiting grooves 403, and the number of the limiting grooves 403 is adapted to the number of the limiting ridges 705. Each limiting ridge 705 can be adapted to one of the limiting grooves 403. The plurality of limiting grooves 403 are arranged in sequence along the circumference of the second fixing portion, and there is a smooth transition between two adjacent limiting grooves 403. When the second pipe fitting 7 is subjected to external force, the third connection end 701 can rotate along its axial direction relative to the second fixing portion, and the limiting ridge 705 switches to other limiting grooves 403. When the external force on the second pipe fitting 7 is removed, under the adaptive limiting action of the limiting ridge 705 and the limiting groove 403, the third connection end 701 together with the second pipe fitting 7 can stop and be limited at the current position.

[0071] The shelf is also provided with a clamping piece 8, which has a clamping socket for clamping the second pipe fitting 7. When the enhanced washing function is not needed, the second pipe fitting 7 can be rotated to the folded position. At this time, the second pipe fitting 7 can be clamped to the clamping socket and maintained in the current position, avoiding the second pipe fitting 7 occupying the shelf placement rate and the washing water flow when not in use.

[0072] Furthermore, the rotating mechanism 4 also includes a ball valve 404 and a rotary switch 405. The ball valve 404 is arranged in the accommodating chamber, the rotary switch 405 is arranged on the second fixed seat 402, and part of the rotary switch 405 extends into the accommodating chamber and is connected to the ball valve 404. Turning the rotary switch 405 can adjust the position state of the ball valve 404 in the accommodating chamber.

[0073] The ball valve 404 is located between the first stopper 603 and the second stopper 704. The ball valve 404 has a water supply channel 4041. When the rotary switch 405 is operated, the ball valve 404 can be switched between an open position and a closed position. In the open position, one end of the water supply channel 4041 is connected to the first connection end 601, and the other end of the water supply channel 4041 is connected to the third connection end 701, thereby supplying water to the second pipe 7. In the closed position, the first connection end 601 and the second connection end 602 respectively abut the spherical outer wall of the ball valve 404, and the water path between the first pipe 6 and the second pipe 7 is blocked.

[0074] Furthermore, the rotating mechanism 4 also includes a compression spring 406, a second seal 407 and a third seal 408, wherein the second seal 407 is arranged at the first connection end 601, and the third seal 408 is arranged at the third connection end 701. When the ball valve 404 is in the about position, the outer wall surface of the ball valve 404 can contact the second seal 407 and the third seal 408, so that the second seal 407 and the third seal 408 play a sealing role.

[0075] The number of the compression springs 406 is one or two. When the number of the compression springs 406 is one, the compression spring 406 is sleeved on the third connecting end 701 in a state of compression to a certain extent, and the compression spring 406 is located between the second limiting portion 704 and the second fixing portion. The compression spring 406 can provide a compression force on the second pipe 7, on the one hand, strengthening the stability between the second pipe 7 and the second fixing portion. On the other hand, by providing the compression spring 406, the second sealing member 407 and the third sealing member 408 can be subjected to the compression force and produce deformation, thereby ensuring the sealing effect on the ball valve 404. When the number of the compression springs 406 is two, one of the compression springs 406 is provided as above, and the other compression spring 406 is sleeved on the second connecting end 602 in a state of moderate compression and located between the first limiting portion 603 and the first fixing portion, as shown in FIG. Figure 6As shown, the diameter length of the ball valve 404 distributed along the axis of the water supply channel 4041 is smaller than the length of other diameters. When the ball valve 404 is switched from the closed position to the open state, the water channel is opened, and the compression spring 406 releases a certain amount of compression, but is still in a compressed state, so that the compression spring 406 can apply elastic force to the first limiting portion 603 and the second limiting portion 704, so that the first connection end 601 and the third connection end 701 can approach the port of the water supply channel 4041, and at the same time, the wall around the port of the water supply channel 4041 can contact the second seal 407 and the third seal 408. At this time, there is still a sealing effect between the ball valve 404 and the second seal 407 and the third seal 408 to avoid water leakage.

[0076] In addition, it should be noted that due to the provision of the compression spring 406, the rotation process of the second tube 7 has a damping effect, and when an external force is applied to the second tube 7 to rotate the second tube 7, the rotation process of the second tube 7 is more textured.

[0077] To sum up, the multifunctional bracket enhanced washing structure provided in the present application has an angle-adjustable branch water pipe group relative to the dishwasher shelf. Whether to use the branch water pipe group can be selected according to the cleaning mode of the dishwasher and the type of dishes or items to be washed. When the branch water pipe group is not in use, the branch water pipe group can be folded up. When the branch water pipe group is in use, the second pipe fitting 7 can be pre-adjusted to adjust the water outlet path and water outlet direction of the enhanced washing, thereby increasing the cleaning range of the multifunctional bracket enhanced washing structure and improving the cleaning effect of the dishes.

[0078] An embodiment of the present application also provides a dishwasher, including the multifunctional bracket enhanced washing structure as described above, and thus has all the beneficial technical effects of the multifunctional bracket enhanced washing structure. The dishwasher provided by the present application effectively expands the coverage of enhanced washing through the above-mentioned multifunctional bracket enhanced washing structure, realizes the adjustable water outlet direction and water outlet path of enhanced washing, and improves the cleaning effect of tableware or items that require enhanced washing.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
