[0048] The first aspect of this application discloses a dishwasher base 100, which, in some embodiments, is combined with Figure 1 , Figure 2 as well as Figures 5 to 10 As shown, the dishwasher base 100 includes a base plate 1000 and a cover 2000. The base plate 1000 is formed with a plurality of grooves 1100, which are spaced apart from each other. The base plate 1000 is also provided with water inlets 1200 that are respectively connected to the plurality of grooves 1100. The cover 2000 is connected to the base plate 1000 and covers the plurality of grooves 1100, thus forming a plurality of water supply channels that are spaced apart from each other. The cover 2000 is provided with connecting seats 2100 that are respectively connected to the plurality of water supply channels.

[0049] The dishwasher base 100 is described in detail below. The dishwasher includes a dishwasher base 100, an inner tub, and a dish rack. The dishwasher base 100 includes a base plate 1000. The inner tub includes a left side panel, a right side panel, a rear side panel, and a top panel. The left side panel, right side panel, rear side panel, and top panel of the inner tub cooperate to form a structure that is open at the front and bottom. When the inner tub is installed on the base, the base plate 1000 surrounds the bottom of the inner tub, thus forming a washing chamber open at the front. The dishwasher door can move between an open position and a closed position. When the door moves to the closed position, the washing chamber is closed; when the door moves to the open position, the washing chamber is open. The dish rack can slide in and out of the washing chamber to load and unload tableware. The dish rack is usually a perforated structure to allow water to flow through and rinse the tableware placed on it. The tableware refers to items to be cleaned by the dishwasher, including but not limited to bowls, plates, cups, pots, knives, forks, and chopsticks.

[0050] Generally, the base plate 1000 is equipped with a water cup 1500. The dishwasher also includes a spray unit and a washing pump. The spray unit is located in the washing chamber, the inlet of the washing pump is connected to the water cup 1500, and the outlet of the washing pump is connected to the spray unit. When the dishwasher is working, a certain amount of water is introduced into the washing chamber. This water converges towards the water cup 1500. The washing pump draws water from the water cup and discharges it towards the spray unit. The water is sprayed out from the spray unit to rinse the dishes. After rinsing the dishes, the water falls back into the water cup 1500 and is drawn back by the washing pump, thus forming a washing cycle. The spray unit includes, but is not limited to, the lower spray arm 5100, the middle spray arm 5200, the top spray arm 5300, and the fixed spray arm 5400 mentioned below. Generally, there are multiple spray units, arranged in different positions in the washing chamber, so as to target the dishes located in different positions for cleaning. In order to direct the water pumped by the washing pump to different spray units, the relevant technology usually requires the installation of multiple pipelines for different spray units. Multiple pipelines result in a large number of parts and complicated assembly.

[0051] Therefore, in this embodiment, the base plate 1000 is formed with multiple grooves 1100, which are spaced apart from each other. The grooves 1100 are recessed and open upwards. The orientation in this document is based on the dishwasher's installation environment; the side of the dishwasher facing away from the ground is the top, and the side closest to the ground is the bottom. The grooves 1100 are used to cooperate with the cover 2000 to form a water supply path. For example, the base plate 1000 is made of plastic and is manufactured by integral molding. During the integral molding process, multiple upward-opening grooves 1100 are simultaneously formed, reducing manufacturing difficulty and ensuring the structural strength of the base plate 1000. "Multiple" in this document means two or more, and can be two, three, four, or more.

[0052] The groove 1100 is used to cooperate with the cover 2000 to form a water supply path. Specifically, the cover 2000 is connected to the base plate 1000 and covers the open side of the groove 1100, thus covering multiple grooves 1100. The cover 2000 covers the grooves 1100 to form a water supply path. Since the multiple grooves 1100 are spaced apart, the multiple water supply paths formed are also spaced apart. It can be understood that there are multiple ways to connect the cover 2000 to the base plate 1000, as long as the cover 2000 is fixed to the base plate 1000 and covers multiple grooves 1100 to form multiple spaced water supply paths. For example, the groove 1100 has a groove wall, and the cover 2000 and the groove wall of the groove 1100 are welded together, thus covering the groove 1100 to form a water supply path.

[0053] As can be seen, by combining the cover 2000 and the base plate 1000, multiple separate water supply channels are directly formed on the base plate 1000. Integrating the water supply channels on the dishwasher base 100 in this way helps to simplify the water channel structure, reduce production difficulty, and improve production efficiency, especially suitable for situations with a large number of water channels.

[0054] The water supply path needs to receive water from the washing pump and pass it to the spray component. Therefore, in this embodiment, the base plate 1000 is also provided with inlets 1200 that are respectively connected to multiple grooves 1100, meaning each groove 1100 is connected to a corresponding inlet 1200. Since the cover 2000 covers the grooves 1100 to form a water supply path, the water supply path is also connected to a corresponding inlet 1200. The cover 2000 is provided with connecting seats 2100 that are respectively connected to multiple water supply paths, meaning each water supply path is connected to a corresponding connecting seat 2100. The connecting seat 2100 is used to connect the spray component. Water discharged from the washing pump can enter the corresponding water supply path through the corresponding inlet 1200, and then be discharged through the corresponding connecting seat 2100 to the corresponding spray component, achieving targeted cleaning.

[0055] Generally, the water discharged from the washing pump can be directed to different inlets 1200 via a water distribution valve 4000. (See also...) Figure 1 As shown, the dishwasher base 100 also includes a water distribution valve 4000, which is adapted to open at least one of a plurality of water inlets 1200. Specifically, the water distribution valve 4000 is connected to the bottom of the base plate 1000 and to the water outlet of the washing pump. The water discharged by the washing pump is delivered to the water distribution valve 4000, which can open at least one of the plurality of water inlets 1200. When the water distribution valve 4000 opens the corresponding water inlet 1200, the water can flow through the water inlet 1200 into the corresponding water supply circuit.

[0056] For example, the plurality of grooves 1100 include a first groove 1110, a second groove 1120, and a third groove 1130. That is, among the plurality of grooves 1100, one groove 1100 is defined as the first groove 1110, one groove 1100 is defined as the second groove 1120, and one groove 1100 is defined as the third groove 1130. The plurality of water inlets 1200 include a first water inlet 1210, a second water inlet 1220, and a third water inlet 1230. That is, the water inlet 1200 connected to the first groove 1110 is the first water inlet 1210, the water inlet 1200 connected to the second groove 1120 is the second water inlet 1220, and the water inlet 1200 connected to the third groove 1130 is the third water inlet 1230. The plurality of connecting seats 2100 includes a first connecting seat 2110, a second connecting seat 2120, and a third connecting seat 2130. That is, the connecting seat 2100 corresponding to the first groove 1110 is the first connecting seat 2110, the connecting seat 2100 corresponding to the second groove 1120 is the second connecting seat 2120, and the connecting seat 2100 corresponding to the third groove 1130 is the third connecting seat 2130. Optionally, the second groove 1120 extends rearward from the second water inlet 1220, the third groove 1130 extends rearward from the third water inlet 1230, and the first groove 1110 extends in the left-right direction, thus making full use of space. The spray components of the dishwasher include a lower spray arm 5100, a middle spray arm 5200, a top spray arm 5300, and a fixed spray arm 5400. The lower spray arm 5100 is connected to a first connecting seat 2110, the middle spray arm 5200 and the top spray arm 5300 are connected to a second connecting seat 2120, and the fixed spray arm 5400 is connected to a third connecting seat 2130.

[0057] When the water distribution valve 4000 controls the opening of the first water inlet 1210, the water discharged by the washing pump enters the first groove 1110 through the first water inlet 1210 to form a water supply path and flows out from the first connecting seat 2110 and finally sprays out from the lower spray arm 5100.

[0058] When the water distribution valve 4000 controls the second water inlet 1220 to open, the water discharged by the washing pump enters the second groove 1120 through the second water inlet 1220 to form a water supply path and flows out from the second connecting seat 2120, and finally sprays out from the middle spray arm 5200 and the top spray arm 5300.

[0059] When the water distribution valve 4000 controls the opening of the third water inlet 1230, the water discharged by the washing pump enters the third groove 1130 through the third water inlet 1230 to form a water supply path and flows out from the third connecting seat 2130 and finally sprays out from the fixed spray arm 5400.

[0060] As described above, the connection between the cover 2000 and the base plate 1000 allows the cover 2000 to cover multiple grooves 1100, thereby forming multiple mutually isolated water supply channels. To improve the reliability of the connection between the cover 2000 and the base plate 1000 and to prevent water from leaking between the cover 2000 and the base plate 1000 into the water supply channels, in some embodiments, combined with... Figure 1 and Figure 2 As shown, the dishwasher base 100 also includes a first welding wire 3100 disposed between the cover 2000 and the base plate 1000. The first welding wire 3100 forms a closed loop, and the cover 2000 and the base plate 1000 are adapted to be welded together by the first welding wire 3100 to cover the groove 1100.

[0061] Specifically, the first welding wire 3100 forms a closed loop for high-frequency welding. Therefore, the first welding wire 3100 includes, but is not limited to, metal welding wires such as steel wire and copper wire. The first welding wire 3100 forms a closed loop and is positioned between the cover 2000 and the base plate 1000. Using a high-frequency welding process, the parts of the cover 2000 that contact and are close to the first welding wire 3100 melt, and the parts of the base plate 1000 that contact and are close to the first welding wire 3100 melt. Thus, the melted parts of the cover 2000 and the base plate 1000 fuse together, and after cooling, they are welded together to achieve a sealed connection, improving the sealing performance between the cover 2000 and the base plate 1000 and effectively preventing water leakage between them. For example, the first welding wire 3100 can be placed between the groove wall of the groove 1100 and the cover 2000, achieving a sealing seal on the groove 1100 after welding.

[0062] In some embodiments, combined with Figure 1 and Figure 2 As shown, the cover 2000 and the base plate 1000 are welded together by the same first welding wire 3100 to cover multiple grooves 1100. As mentioned above, the base plate 1000 is formed with multiple grooves 1100. If each groove 1100 is provided with a first welding wire 3100, then the number of first welding wires 3100 needs to be consistent with the number of grooves 1100. When there are more grooves 1100, there are also more first welding wires 3100. Since the first welding wires 3100 need to be placed between the cover 2000 and the base plate 1000, multiple first welding wires 3100 will be detrimental to the welding process.

[0063] Therefore, in this embodiment, the cover 2000 and the base plate 1000 are welded together using the same first welding wire 3100 to cover multiple grooves 1100. That is, whether there are two grooves 1100, three grooves 1100, or more grooves 1100, they are all covered by welding with one first welding wire 3100. In other words, the shape of this first welding wire 3100 is pre-processed to adapt to the arrangement of multiple grooves 1100. First, this first welding wire 3100 is placed on the base plate 1000, and then the cover 2000 is placed. In this way, the cover 2000 and the base plate 1000 can clamp the first welding wire 3100, and then the welding operation is performed to achieve the welding and fixing of the cover 2000 and the base plate 1000, simplifying the processing.

[0064] In some embodiments, where the cover 2000 and the base plate 1000 are welded together using the same first welding wire 3100 to cover multiple grooves 1100, the first welding wire 3100 is welded end-to-end (i.e., the beginning and end of the first welding wire 3100 are welded together) to form a closed loop. See [reference needed]. Figure 4 Welding point I. The first welding wire 3100 forms a closed loop by welding the beginning and end of the first welding wire 3100 together, without the need to weld multiple sections of welding wire. This reduces the difficulty of forming a closed loop with the first welding wire 3100. Furthermore, the welding of the beginning and end of the first welding wire 3100 together ensures the strength of the connection and prevents breakage to the greatest extent.

[0065] In some embodiments, combined with Figures 1 to 10 As shown ( Figure 10 This is a schematic diagram of a cap covering the first groove (the cap covers the second and third grooves in a similar manner). The multiple grooves 1100 include a first groove 1110, a second groove 1120, and a third groove 1130. For example, among the three grooves 1100, one groove 1100 is defined as the first groove 1110, one groove 1100 is defined as the second groove 1120, and one groove 1100 is defined as the third groove 1130.

[0066] Since the base plate 1000 is provided with water inlets 1200 that are respectively connected to multiple grooves 1100, the number of water inlets 1200 is also multiple. The multiple water inlets 1200 include a first water inlet 1210, a second water inlet 1220 and a third water inlet 1230. That is, the water inlet 1200 connected to the first groove 1110 is the first water inlet 1210, the water inlet 1200 connected to the second groove 1120 is the second water inlet 1220, and the water inlet 1200 connected to the third groove 1130 is the third water inlet 1230.

[0067] Typically, the first inlet 1210, the second inlet 1220, and the third inlet 1230 need to be close to each other to better cooperate with the water distribution valve 4000. That is to say, the corresponding parts of the first groove 1110, the second groove 1120, and the third groove 1130 need to be close to each other. For example, the second inlet 1220 and the third inlet 1230 are located at the ends of the second groove 1120 and the third groove 1130 that are close to each other, and the connecting seat 2100 (the second connecting seat 2120 and the third connecting seat 2130) is located at the other ends of the second groove 1120 and the third groove 1130 that are close to each other. In this way, the second inlet 1220 and the third inlet 1230 are close to each other, and the second connecting seat 2120 and the third connecting seat 2130 are close to each other, which makes it easier to cooperate with other components.

[0068] Since the cap 2000 is welded to the base plate 1000 using the same first welding wire 3100 to cover the first groove 1110, the second groove 1120, and the third groove 1130, if the first welding wire 3100 is directly arranged along the groove walls of the first groove 1110, the second groove 1120, and the third groove 1130, the first welding wire 3100 needs to be bent at the positions where the first groove 1110, the second groove 1120, and the third groove 1130 are close to each other, and the bent parts need to be kept from contacting each other. If the bent parts of the first welding wire 3100 contact each other, the welding effect at this point will be weakened. Therefore, the corresponding groove wall needs to be thickened to have enough space to support the bent parts of the first welding wire 3100. The thickening of the groove wall will narrow the width of the corresponding groove 1100, which is not conducive to hydraulic design.

[0069] Therefore, in this embodiment, the second groove 1120 has a second stop 1121 on its groove wall, and the second stop 1121 is located in the axial direction of the second water inlet 1220; the third groove 1130 has a third stop 1131 on its groove wall, and the third stop 1131 is located in the axial direction of the third water inlet 1230; a portion of the groove wall of the first groove 1110, the second stop 1121 and the third stop 1131 constitute a support structure 1300, and at least a portion of the first welding wire 3100 is disposed on the support structure 1300.

[0070] The aforementioned portion of the groove wall of the first groove 1110, the second stop 1121, and the third stop 1131 are located close to each other in the first groove 1110, the second groove 1120, and the third groove 1130. The support mechanism 1300 is formed by the portion of the groove wall of the first groove 1110, the second stop 1121, and the third stop 1131, which increases the arrangement space of the first welding wire 3100 in this position. The arrangement of the first welding wire 3100 in this position is more flexible, and the bent part of the first welding wire 3100 is less likely to come into contact in this position. For example, the portion of the groove wall of the first groove 1110, the second stop 1121, and the third stop 1131 are formed as one piece to form the support structure 1300. After welding with the cover 2000, a relatively large welding area is formed, which improves the welding and sealing effect. It is understandable that when the second stop 1121 and the third stop 1131 are not present, the cover 2000 is welded to the bottom plate 1000, and the corresponding part of the cover 2000 will also be located in the axial direction of the second inlet 1220 and the third inlet 1230. Therefore, in this embodiment, by setting the second stop 1121 and the third stop 1131, the impact on the hydraulics is negligible (compared to the case where they are not set).

[0071] In some embodiments, combined with Figure 3 and Figure 6 As shown, the support structure 1300 has a support plane for supporting a portion of the first welding wire 3100. The first welding wire 3100 needs to be wound to correspond to the shapes of the first groove 1110, the second groove 1120, and the third groove 1130. During welding, the first welding wire 3100 is first placed on the base plate 1000, with a portion of the first welding wire 3100 supported on the support plane, and the remaining portion supported on the remaining groove walls of the first groove 1110, the second groove 1120, and the third groove 1130. The support plane allows for fine-tuning of the shape of the portion of the first welding wire 3100 supported on it, making it more suitable for this position. At the same time, the support plane makes it easier to form a relatively large area of ​​fusion, further improving the sealing reliability of this position. Based on this, in some embodiments, the cover 2000 includes a welding plane that covers the support plane to clamp a portion of the first welding wire 3100. The support plane and the welding plane clamp the first welding wire 3100, improving the welding effect.

[0072] In some embodiments, combined with Figure 1 , Figure 2 and Figure 5 As shown, the base plate 1000 is provided with a baffle 1400. The two ends of the baffle 1400 are respectively connected to the groove wall of the first groove 1110 to surround the second groove 1120 and the third groove 1130. The cover 2000 also covers the space surrounded by the baffle 1400.

[0073] Specifically, the positions of the first water inlet 1210, the second water inlet 1220, and the third water inlet 1230 depend on the arrangement of the water distribution valve 4000 on the dishwasher chassis. In some cases, the arrangement of the first groove 1110, the second groove 1120, and the third groove 1130 is not symmetrical, and the shape of the cover 2000 also needs to be compatible with the overall arrangement of the first groove 1110, the second groove 1120, and the third groove 1130. Thus, when the cover 2000 is closed on the bottom plate 1000, a seam is formed between the cover 2000 and the bottom plate 1000. The presence of the seam will bring a sense of separation, especially in the case of asymmetry, the user will have a stronger sense of separation.

[0074] Therefore, in this embodiment, the base plate 1000 is provided with a baffle 1400, the two ends of which are connected to the groove wall of the first groove 1110 to surround the second groove 1120 and the third groove 1130. The cover 2000 also covers the space surrounded by the baffle 1400. That is to say, the shape of the cover 2000 also needs to be adapted to the arrangement of the baffle 1400. Through the setting of the baffle 1400, the overall arrangement of the baffle 1400, the first groove 1110, the second groove 1120 and the third groove 1130 is more regular and symmetrical, that is, the overall shape and structure of the cover 2000 is more regular and symmetrical, reducing the sense of discontinuity. In addition, the space surrounded by the baffle 1400 forms a hollow, which can also reduce the amount of material used in the base plate 1000.

[0075] For example, Figure 5 As shown, the first groove 1110 is U-shaped, and each end of the first groove 1110 corresponds to a connecting seat 2100 (first connecting seat 2110). The second inlet 1220 is located at one end of the second groove 1120, which extends obliquely backward from the second inlet 1220. The second connecting seat 2120 corresponds to the other end of the second groove 1120. The third inlet 1230 is located at one end of the third groove 1130, which extends obliquely backward from the third inlet 1230. The third connecting seat 2130 corresponds to the other end of the third groove 1130. One end of the baffle 1400 is connected to the groove wall at one end of the first groove 1110, and the other end of the baffle 1400 is connected to the groove wall at the other end of the second groove 1120, thus the baffle 1400 surrounds the second groove 1120 and the third groove 1130. The shapes of the cover 2000, the baffle 1400, the first groove 1110, the second groove 1120 and the third groove 1130 are matched, making the cover 2000 more regular and symmetrical overall.

[0076] In some embodiments, combined with Figures 1 to 5As shown, the dishwasher base 100 also includes a second welding wire 3200 disposed between the cover 2000 and the base plate 1000. A portion of the first welding wire 3100 and the second welding wire 3200 form a closed loop. The cover 2000 and the base plate 1000 are also adapted to be welded by the second welding wire 3200 to cover the space surrounded by the baffle 1400.

[0077] Specifically, the second welding wire 3200 forms a closed loop for high-frequency welding. Therefore, the second welding wire 3200 includes, but is not limited to, metal welding wires such as steel wire and copper wire. The second welding wire 3200 is placed between the cover 2000 and the base plate 1000 and forms a closed loop with the part of the first welding wire 3100. Using high-frequency welding technology, based on the welding by the first welding wire 3100, the part of the cover 2000 that contacts and is close to the second welding wire 3200 melts, and the part of the base plate 1000 that contacts and is close to the second welding wire 3200 melts, thus achieving the covering of the space surrounded by the baffle 1400.

[0078] To facilitate the cooperation of the first welding wire 3100 and the second welding wire 3200 to form a closed loop, in some embodiments, combined with Figure 4 As shown, one end of the second welding wire 3200 is welded to the first welding wire 3100, and the other end of the second welding wire 3200 is welded to the beginning and end of the first welding wire 3100. In this way, only two welding points are needed to form two closed loops (see welding point I and welding point II in the attached figure). One closed loop is used to cover the first groove 1110, the second groove 1120 and the third groove 1130, and the other closed loop is used to cover the space surrounded by the baffle 1400.

[0079] Optionally, the cover 2000 is also provided with a receiving groove 2200. The groove walls of the first groove 1110, the second groove 1120, the third groove 1130, and the baffle 1400 respectively engage with the receiving groove 2200 to hold the first welding wire 3100 and the second welding wire 3200. That is, when installing the cover 2000, the groove walls of the first groove 1110, the second groove 1120, the third groove 1130, and the baffle 1400 engage with the corresponding receiving grooves 2200, achieving the initial positioning of the cover 2000 during installation. At the same time, it can increase the contact area with the first welding wire 3100 and the second welding wire 3200, and improve the reliability of welding.
