[0037] This application discloses a dishwasher, which in some embodiments combines Figures 1 to 8 As shown, the dishwasher includes a base 1000, an inner water pipe 2000 and a branch water pipe 3000. The inner water pipe 2000 is connected to the base 1000, and the branch water pipe 3000 is connected to the inner water pipe 2000 to receive water from the inner water pipe 2000. The branch water pipe 3000 is also fitted and connected to the base 1000.

[0038] In this embodiment, the branch water pipe 3000 is connected to the inner water pipe 2000 and also fits into the base 1000. This fitting connection allows the branch water pipe 3000 and the base 1000 to be quickly fixed together without the need for additional fasteners. This convenient operation does not hinder the pushing and pulling of the dish rack and helps to improve the user experience.

[0039] A dishwasher is a device used to clean dishes. Generally, a dishwasher includes an inner tub, a base, a dish rack, spray arms, and a wash pump.

[0040] The inner tub is installed on the base 1000 to enclose the washing chamber and forms an inlet and outlet that communicate with the washing chamber. The dishwasher door can move between the open position and the closed position. When the door moves to the closed position, the inlet and outlet are closed. When the door moves to the open position, the inlet and outlet are opened. There are multiple ways for the door to move. For example, it can be designed to rotate from top to bottom to open the inlet and from bottom to top to close the inlet and outlet.

[0041] The dish rack slides in and out of the washing chamber to load and unload tableware. The rack is typically perforated to allow water to flow through and rinse the tableware placed on it. Tableware refers to items that are washed by the dishwasher, including but not limited to bowls, plates, cups, pots, knives, forks, and chopsticks.

[0042] The spray arm is located in the washing chamber and is used to spray water towards the dishes. The spraying of water by the spray arm is achieved by the operation of the washing pump. The water inlet of the washing pump is connected to the bottom of the washing chamber to communicate with the washing chamber, and the water outlet of the washing pump is connected to the spray arm. The washing pump draws water from the washing chamber and delivers it to the spray arm, so that the water is sprayed out from the nozzle of the spray arm to rinse the dishes. After rinsing the dishes, the water flows back to the bottom of the washing chamber and is drawn in by the washing pump again, thus forming a washing cycle.

[0043] Generally speaking, a spray arm consists of multiple spray arms arranged in a vertical direction, where multiple means two or more. For example, a spray arm may include an upper spray arm, a middle spray arm, and a lower spray arm. The upper spray arm, middle spray arm, and lower spray arm are connected by an inner water pipe 2000 installed in the washing chamber. The water pumped by the washing pump enters the inner water pipe 2000. When the water flows along the inner water pipe 2000, it can be divided to the upper spray arm, middle spray arm, and lower spray arm. The water can be sprayed out from the upper spray arm, middle spray arm, and lower spray arm respectively to clean the tableware.

[0044] Most current spray arms clean tableware by rotating and spraying water. However, this method may be less effective for deep containers. To address this, related technologies connect a branch water pipe 3000 to an inner water pipe 2000. The branch water pipe 3000 extends from the inner water pipe 2000 to a position corresponding to the container. Water from the inner water pipe 2000 is diverted to the branch water pipe 3000 and sprayed out from there, thus enhancing the cleaning of the container. There are various ways to connect the branch water pipe 3000 and the inner water pipe 2000, as long as water flows from the inner water pipe 2000 into the branch water pipe 3000. For example, the branch water pipe 3000 and the inner water pipe 2000 can each have corresponding holes for connection via a plug-in joint. A sealing ring is typically installed at the connection point between the branch water pipe 3000 and the inner water pipe 2000 to prevent leakage.

[0045] Taking a deep container with a certain depth, such as a cup, as an example, the cup is placed on the dish rack. The branch water pipe 3000 is equipped with a nozzle 3200, which corresponds to the opening of the cup. Water can be sprayed from the nozzle 3200 to the inside of the cup, thus cleaning it. Typically, the dish rack has a folding bracket. When cups need to be placed, the bracket is switched to the unfolded position, and the cups can be clipped into the bracket for placement. When cups are not needed, the bracket is switched to the storage position to avoid taking up space.

[0046] Since the branch water pipe 3000 extends from the inner water pipe 2000 to the corresponding position, it needs to be further secured to improve the installation stability of the branch water pipe 3000. In some solutions, the branch water pipe 3000 needs to be connected with screws, but this method is slightly inconvenient to operate in the limited space of the washing chamber. In other solutions, the branch water pipe 3000 needs to be connected to the dish rack, but this will hinder the pushing and pulling movement of the dish rack.

[0047] Therefore, in this embodiment, the branch water pipe 3000 and the base 1000 are designed to be interlocked. The branch water pipe 3000 and the base 1000 are connected to form a support point, which, together with the branch water pipe 3000 and the inner water pipe 2000, forms a support point, thus achieving stable installation of the branch water pipe 3000. The so-called interlocking connection means that at least a portion of one of the branch water pipe 3000 and the base 1000 is embedded in at least a portion of the other. This allows for rapid assembly, eliminating the need for additional tools to operate fasteners for subsequent tightening. Compared to using screws, the interlocking connection is simpler and more convenient. Furthermore, since the branch water pipe 3000 is connected to the base 1000, it does not need to be connected to the dish rack, and the pushing and pulling movement of the dish rack is not affected.

[0048] The interlocking connection can be implemented using the following schemes; in some embodiments, it combines... Figure 1 As shown, one of the branch water pipe 3000 and the base 1000 is provided with a groove 1100, and the other of the branch water pipe 3000 and the base 1000 is provided with a protrusion 3100. The protrusion 3100 is engaged with the groove 1100 to achieve a fitting connection between the branch water pipe 3000 and the base 1000. Alternatively, the branch water pipe 3000 may have a protrusion 3100 and the base 1000 may have a corresponding groove 1100, or the branch water pipe 3000 may have a groove 1100 and the base 1000 may have a corresponding protrusion 3100. The fitting connection between the protrusion 3100 and the groove 1100 is convenient. The protrusion 3100 engages with the groove 1100, and the protrusion 3100 and the groove 1100 mutually constrain each other. This, combined with the connection between the branch water pipe 3000 and the inner water pipe 2000, achieves stable installation of the branch water pipe 3000.

[0049] The following embodiment uses a branch water pipe 3000 with a locking protrusion 3100 and a base 1000 with a locking groove 1100 as an example for illustration. A branch water pipe 3000 with a locking groove 1100 and a base 1000 with a locking protrusion 3100 have similar technical effects and will not be repeated. It is understood that the locking protrusion 3100 engaging with the locking groove 1100 is a result of relative movement. This can be that the locking protrusion 3100 moves while the locking groove 1100 remains stationary, or the locking groove 1100 remains stationary while the locking protrusion 3100 moves, or both the locking protrusion 3100 and the locking groove 1100 move.

[0050] In some embodiments, combined with Figures 2 to 8 As shown, the slot 1100 includes a first slot wall portion 1110 and a second slot wall portion 1120. The second slot wall portion 1120 is provided on opposite sides of the first slot wall portion 1110, and the slot protrusion 3100 is engaged between the second slot wall portions 1120 on opposite sides.

[0051] The second groove wall portion 1120 on one side of the first groove wall portion 1110 and the second groove wall portion 1120 on the other side of the first groove wall portion 1110 are arranged alternately, so that a certain space is enclosed between the first groove wall portion 1110 and the second groove wall portions 1120 on the opposite sides. This space is defined as the receiving cavity 1150. The locking protrusion 3100 is locked between the second groove wall portions 1120 on the opposite sides, that is, locked into the receiving cavity 1150. In this way, the opposite sides of the locking protrusion 3100 are limited, improving the installation stability of the branch water pipe 3000.

[0052] For example, combining Figure 3 As shown, an inlet 1160 is formed between one end of the first groove wall portion 1110 and one end of the second groove wall portions 1120 on opposite sides. A locking protrusion 3100 is adapted to engage with the second groove wall portions 1120 on opposite sides through the inlet 1160. That is, the inlet 1160 communicates with the receiving cavity 1150, and the locking protrusion 3100 engages with the receiving cavity 1150 from the inlet 1160, thereby engaging with the second groove wall portions 1120 on opposite sides. More specifically, the locking protrusion 3100 engages with the receiving cavity 1150 along a first direction, thus being located between the second groove wall portions 1120 on opposite sides. The orientation of the second groove wall portions 1120 on opposite sides is a second direction, which is perpendicular to the first direction. A third direction is defined as perpendicular to both the second and first directions. Thus, the locking protrusion 3100 is limited by the cooperation of the first groove wall portion 1110 and the second groove wall portions 1120 on opposite sides in the second and third directions.

[0053] In some embodiments, combined with Figure 3 and Figure 5 As shown, the second groove wall portions 1120 on opposite sides are inclined toward each other from the first groove wall portion 1110.

[0054] A receiving cavity 1150 is formed between the first groove wall portion 1110 and the second groove wall portions 1120 on both sides. A clearance opening 1170 communicating with the receiving cavity 1150 is provided between the second groove wall portions 1120 on both sides. When the locking protrusion 3100 is inserted into the receiving cavity 1150 and located between the clearance groove wall portions on both sides, the remaining part of the branch water pipe 3000 needs to pass through the clearance opening 1170. That is, during the process of the locking protrusion 3100 being inserted into the receiving cavity 1150 from the inlet 1160, the clearance opening 1170 avoids the movement of the branch water pipe 3000, so that the locking protrusion 3100 can be inserted into the predetermined position. Since the protrusion 3100 needs to be engaged by the second groove wall portions 1120 on both sides, to ensure effective engagement of the protrusion 3100, the second groove wall portions 1120 on both sides are inclined towards each other from the first groove wall portion 1110. This reduces the distance between the clearance opening 1170 and the first groove wall portion 1110, thus reducing space occupation. If the receiving cavity 1150 and the clearance opening 1170 form a T-shaped structure, then while ensuring the same engagement effect, the distance between the clearance opening 1170 and the first groove wall portion 1110 will be greater, occupying more space.

[0055] In addition, combined Figure 5 and Figure 7 As shown, a retaining cavity 1151 is formed between the second groove wall portion 1120 and the first groove wall portion 1110. The retaining cavity 1151 is part of the receiving cavity 1150. When the retaining protrusion 3100 is engaged in the receiving cavity 1150, the opposite sides of the retaining protrusion 3100 are located in the corresponding retaining cavity 1151 and are engaged. The opposite sides of the retaining protrusion 3100 are formed with corner portions 3110 that are similar in shape to the retaining cavity 1151. The corner portions 3110 are engaged in the retaining cavity 1151. The so-called similarity means that the shape is similar. By using the corner portions 3110 that are similar in shape to the retaining cavity 1151, the contact area between the corner portions 3110 and the cavity wall of the retaining cavity 1151 can be increased, thereby further improving stability.

[0056] In some embodiments, the slot 1100 further includes a third slot wall portion 1130, which is disposed opposite to the inlet 1160. The third slot wall portion 1130 is adapted to stop the protrusion 3100 in the moving direction of the protrusion 3100 when the protrusion 3100 is engaged in the slot 1100.

[0057] For example, the third groove wall portion 1130 is located at the other end of the first groove wall portion 1110 and the other end of the second groove wall portions 1120 on both sides. When the locking protrusion 3100 is inserted from the inlet 1160 between the second groove wall portions 1120 on both sides, as the locking protrusion 3100 moves until it encounters the third groove wall portion 1130, it is blocked by the third groove wall portion 1130, which serves as a limit and also serves as a reminder that the installation is in place.

[0058] Optionally, in some embodiments, the branch water pipe 3000 is adapted to move from top to bottom so that the locking protrusion 3100 engages with the locking slot 1100.

[0059] As mentioned above, the branch water pipe 3000 and the inner water pipe 2000 are connected. Generally, the inner water pipe 2000 needs to be connected to the connecting seat of the base plate of the base 1000. The inner water pipe 2000 needs to be installed into the connecting seat from top to bottom. Based on this, in this embodiment, the branch water pipe 3000 is adapted to move from top to bottom so that the locking protrusion 3100 is engaged in the locking groove 1100. In this way, the inner water pipe 2000 and the branch water pipe 3000 can be assembled in advance. During the installation process into the base 1000, the inner water pipe 2000 moves from top to bottom and is installed into the connecting seat. The branch water pipe 3000 also moves from top to bottom so that the locking protrusion 3100 is engaged in the locking groove 1100, further improving the ease of assembly.

[0060] See Figures 1 to 8 As shown, taking the branch water pipe 3000 with the locking protrusion 3100 as an example, the locking groove 1100 is located on the right side of the base 1000. At this time, the first direction is from top to bottom, the second direction is the front and back direction, and the third direction is the left and right direction. Through the cooperation of the locking protrusion 3100 and the locking groove 1100, the locking protrusion 3100 is limited in the top to bottom direction, the front and back direction, and the left and right direction. With the connection between the branch water pipe 3000 and the inner water pipe 2000, the branch water pipe 3000 is effectively supported.

[0061] In some embodiments, combined with Figure 2 and Figure 3 As shown, the base 1000 includes a locking part 1140, which is disposed on the first groove wall part 1110 and located on the moving path of the locking protrusion 3100. The locking part 1140 is adapted to stop the locking protrusion 3100 in the opposite direction of the moving direction of the locking protrusion 3100.

[0062] When the branch water pipe 3000 and the base 1000 are engaged and connected via the latching protrusion 3100 and the latching groove 1100, the latching protrusion 3100 and the latching groove 1100 may accidentally disengage in the opposite direction of the engagement. Therefore, in this embodiment, the base 1000 also includes a locking part 1140. When the latching protrusion 3100 is engaged in the latching groove 1100, the latching protrusion 3100 is stopped by the locking part 1140 in the opposite direction of the engagement, preventing the latching protrusion 3100 from accidentally disengaging from the latching groove 1100 in the opposite direction of the engagement, thus further improving stability. It is understood that the movement of the latching protrusion 3100 and the latching groove 1100 is relative; the latching protrusion 3100 engaging in the latching groove 1100 is with the latching groove 1100 stationary as a reference.

[0063] The structure of the locking part 1140 is as follows, combined with Figure 4As shown, the locking part 1140 includes a guide slope 1141 and an abutment surface 1142. The guide slope 1141 is adapted to guide the locking protrusion 3100 past the locking part 1140, and the abutment surface 1142 is adapted to stop the locking protrusion 3100 after it has passed the locking part 1140.

[0064] See Figure 8 As shown, taking the branch water pipe 3000 with a locking protrusion 3100 as an example, the locking groove 1100 is located on the right side of the base 1000, and the locking part 1140 is located on the first groove wall 1110. The locking protrusion 3100 is aligned with the inlet 1160 of the locking groove 1100. The branch water pipe 3000 moves from top to bottom, causing the locking protrusion 3100 to engage between the second groove walls 1120 on opposite sides. When the branch water pipe 3000 moves the locking protrusion 3100 from top to bottom, it will encounter the guide slope 1141 and generate mutual force. Under the action of the inclined surface 1141, at least one of the latching protrusion 3100 and the locking part 1140 deforms to avoid collision, so that the latching protrusion 3100 passes over the locking part 1140 until the latching protrusion 3100 and the third groove wall part 1130 abut to engage in place. At the moment when the latching protrusion 3100 passes over the locking part 1140, at least one of the latching protrusion 3100 and the locking part 1140 returns to its original position. Thus, the abutting surface 1142 abuts against the upper surface of the latching protrusion 3100, and the latching protrusion 3100 is blocked by the abutting surface 1142 when it tries to move upward and disengage from the slot 1100. In order to facilitate the deformation avoidance of at least one of the latching protrusion 3100 and the locking part 1140, the part of the base 1000 used for fitting and connecting with the branch water pipe 3000 is molded with plastic. The plastic material is more prone to elastic deformation. Similarly, the part of the branch water pipe 3000 used for fitting and connecting with the base 1000 is molded with plastic.

[0065] In some embodiments, combined with Figure 1 As shown, the branch water pipe 3000 extends along the side wall of the base 1000. This side wall of the base 1000 also provides some restraint for the branch water pipe 3000, improving its stability. For example, the side wall of the base 1000 has a groove 1100, and the branch water pipe 3000 has a corresponding protrusion 3100. The protrusion 3100 is engaged with the groove 1100, thus allowing the branch water pipe 3000 to extend along the side wall of the base 1000. Furthermore, this arrangement allows the branch water pipe 3000 to avoid the water flow from the rotating spray arm to the greatest extent possible, ensuring effective cleaning.

[0066] In some embodiments, combined with Figure 1 and Figure 6As shown, the dishwasher includes a dish rack positioned above a branch water pipe 3000. The dish rack includes a bracket for supporting deep-mouthed containers. The branch water pipe 3000 has an auxiliary branch 3300 extending away from the side wall of the base 1000. The auxiliary branch 3300 is equipped with a nozzle 3200 facing the bracket. By aligning the nozzle 3200 with the bracket, when the deep-mouthed container is supported on the bracket, the nozzle 3200 can be aligned with the opening of the deep-mouthed container.

[0067] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
