The second dish rack is located within the cleaning chamber and below the first dish rack. The second spray arm is also located within the cleaning chamber and is connected to the water supply system; liquid from the water supply system is sprayed onto the second dish rack via the second spray arm, thereby cleaning the dishes on the second dish rack. The replaceable spray arm is selectively connected to the water supply system; when connected, liquid from the water supply system is sprayed onto the second dish rack via the first spray arm.

[0075] When regular cleaning is required, the replaceable spray arm can be disconnected from the water supply system. The replaceable spray arm is located outside the cabinet, while the first dish rack and the first spray arm are located inside the cabinet. The first spray arm is connected to the water supply system. Tableware can be placed on the first and second dish racks.

[0076] When large dishes need to be washed, the first dish rack and the first spray arm can be removed to increase the space at the top of the second dish rack, allowing it to accommodate larger dishes. Furthermore, by simultaneously spraying liquid onto the second dish rack using the second spray arm and the replaceable spray arm, the washing effect is enhanced.

[0095] The first dish basket 300 is detachably connected to the housing. This allows the first dish basket 300 to be disassembled and moved to the outside of the housing. Alternatively, the first dish basket 300 can be installed inside the cleaning chamber.

[0096] Figure 4 is a schematic diagram of the structure of the first spray arm, the second spray arm, and the water supply system in the dishwasher provided in the embodiment of this application.

[0097] Referring to Figures 2 and 4, in some embodiments, the dishwasher includes a first spray arm 400. The first spray arm 400 is used to spray liquid onto a first dish rack 300.

[0098] Specifically, the first spray arm 400 is optionally connected to the water supply system 200. Specifically, when the first dish basket 300 is located inside the cleaning chamber, the first spray arm 400 is connected to the water supply system 200. When the first dish basket 300 is not located inside the cleaning chamber, the first spray arm 400 is not connected to the water supply system 200, and the first spray arm 400 can be placed outside the cleaning chamber.

[0099] When the first spray arm 400 is connected to the water supply system 200, the liquid in the water supply system 200 is sprayed onto the first dish basket 300 through the first spray arm 400, thereby cleaning the tableware in the first dish basket 300.

[0100] Referring to Figures 1 to 3, in some embodiments, the dishwasher includes a second dish rack 500. The second dish rack 500 is used to hold tableware.

[0101] The second bowl basket 500 is located in the cleaning chamber and below the first bowl basket 300.

[0102] Referring to Figure 4, in some embodiments, the dishwasher includes a second spray arm 600. The second spray arm 600 is used to spray liquid onto the second dish rack 500.

[0103] The second spray arm 600 is located in the cleaning chamber and is connected to the water supply system 200. The liquid in the water supply system 200 is sprayed onto the second bowl 500 through the second spray arm 600.

[0107] It should be noted that as the first basket 300 moves outward from the housing, the first spray arm 400 disengages from the water supply system 200. When the first basket 300 moves inward to its limit position, the first spray arm 400 reconnects to the water supply system 200. Therefore, in Figures 2 and 4, the first spray arm 400 is disengaged from the water supply system 200 during the movement of the first basket 300 outward from the housing.

[0108] It should be noted that when the dishwasher is washing a small amount of dishes, it can perform single-layer washing. That is, the first dish rack 300 can be placed outside the cleaning chamber, and the first spray arm 400 can be disconnected from the water supply system 200; a small amount of dishes can then be placed in the second dish rack 500. To improve the cleaning effect, the spray arm 700 can be connected to the water supply system 200, and the liquid in the water supply system 200 can be sprayed onto the second dish rack 500 via the first spray arm 400. Alternatively, the second spray arm 600 can be connected to the water supply system 200, and the liquid in the water supply system 200 can be sprayed onto the second dish rack 500 via the second spray arm 600.

[0109] Referring to Figure 3, when the dishwasher is washing large dishes, the first dish rack 300 is not located in the cleaning chamber, and the first spray arm 400 is not connected to the water supply system 200. The large dishes are placed in the second dish rack 500. The replaceable spray arm 700 is then connected to the water supply system 200, and the liquid in the water supply system 200 is sprayed onto the second dish rack 500 via the first spray arm 400. The second spray arm 600 is connected to the water supply system 200, and the liquid in the water supply system 200 is sprayed onto the second dish rack 500 via the second spray arm 600.

The cabinet has a cleaning chamber. The door is connected to the cabinet to open or close the cleaning chamber. A portion of the water supply system 200 is located in the cleaning chamber and is connected to a water source. The first spray arm 400 is selectively connected to the water supply system 200. When connected, liquid in the water supply system 200 is sprayed through the first spray arm 400 onto the first dish rack 300, thereby cleaning the dishes on the first dish rack 300. The second dish rack 500 is located in the cleaning chamber and below the first dish rack 300. The second spray arm 600 is located in the cleaning chamber and is connected to the water supply system 200. Liquid in the water supply system 200 is sprayed onto the second dish rack 500 via the second spray arm 600, thereby cleaning the tableware on the second dish rack 500. A replaceable spray arm 700 can be selectively connected to the water supply system 200. When connected, liquid in the water supply system 200 is sprayed onto the second dish rack 500 via the first spray arm 400. When large tableware needs to be cleaned, the first dish rack 300 and the first spray arm 400 can be removed, increasing the space at the top of the second dish rack 500, allowing it to accommodate larger tableware. Furthermore, simultaneously spraying liquid onto the second dish rack 500 using both the second spray arm 600 and the replaceable spray arm 700 enhances the cleaning effect.

[0111] Referring to Figure 4, in some embodiments, the water supply system 200 is provided with a first connection port 210, which is connected to the second spray arm 600 or the replaceable spray arm 700. In this way, the second spray arm 600 and the replaceable spray arm 700 share a single port, thereby reducing the number of ports and lowering processing costs.

[0112] In some embodiments, the water supply system 200 includes a water pump. The water pump provides power to the liquid.

[0113] In some embodiments, the water supply system 200 includes a water distribution valve. The function of the water distribution valve is to control the direction and distribution of water flow to ensure that water can effectively reach each cleaning area inside the dishwasher. The water distribution valve is connected to a water pump.

[0114] In some embodiments, the water supply system 200 includes a water supply pipe 220, which is used to communicate with a water distribution valve and with a second spray arm 600 and a replaceable spray arm 700. Specifically, a first connection port 210 is provided on the water supply pipe 220.

[0115] The water supply pipe 220 includes a horizontal section 221 and a vertical section 222 connected to each other. The horizontal section 221 is located at the bottom of the second basket 500, and the vertical section 222 is located behind the first basket 300 and the second basket 500. The horizontal section 221 extends in the same direction as the depth of the housing, and the vertical section 222 extends in the same direction as the height of the housing. The depth of the housing is shown by the Y-axis in Figure 1, and the height of the housing is shown by the Z-axis in Figure 1. The first connection port 210 is located in the vertical section 222.

[0116] In some embodiments, the first connection port 210 includes a boss. The boss is cylindrical. The boss is provided with a connection hole, which communicates with the inner cavity of the water supply pipe 220. The first connection port 210 includes a ball and an elastic element. The ball is disposed in the connection hole, and the elastic element is connected to the ball and to the water supply pipe 220. Under the action of an external force, the ball compresses the elastic element, and the ball moves toward the water supply pipe 220, thereby opening the connection hole. After the external force is removed, the ball moves outward under the elastic action of the elastic element, thereby closing the connection hole. When the second spray arm 600 or the replaceable spray arm 700 is connected to the first connection port 210, it can be sleeved on the outside of the boss, and an external force is applied to the ball, thereby making the second spray arm 600 or the replaceable spray arm 700 communicate with the water supply pipe 220. After the second spray arm 600 or the replaceable spray arm 700 is disassembled, the ball closes the connection hole, thereby effectively preventing liquid in the water supply pipe 220 from flowing out through the first port.

[0117] The elastic element can be a spring. The sphere can be a steel ball.

[0118] In some embodiments, the water supply system 200 is provided with a first connection port 210 and a second connection port. The first connection port 210 is used to connect to the second spray arm 600, and the second connection port is used to connect to the replaceable spray arm 700.

[0119] In some embodiments, the second spray arm 600 is located below the second dish rack 500, and the replaceable spray arm 700 is located above the second dish rack 500. This allows the dishes in the second dish rack 500 to be rinsed from two directions, improving the cleaning effect.

[0120] Figure 5 is a partial enlarged view of point A in Figure 3, Figure 6 is a structural schematic diagram of the replaceable spray arm 700 in the dishwasher provided in the embodiment of this application, and Figure 7 is a structural schematic diagram of Figure 6 from another angle.

[0121] Referring to Figures 5 to 7, in some embodiments, the replaceable spray arm 700 includes a main body 710.

[0122] The main body 710 has a first inner cavity, and the main body 710 is plugged into the water supply system 200 so that the first inner cavity is connected to the inner cavity of the water supply system 200. In this way, the connection is made by plugging in, which makes the connection more convenient.

[0123] Specifically, the main body 710 is fitted onto the boss, and the first inner cavity communicates with the connecting hole. The inner wall of the first inner cavity is provided with a protrusion 711, which protrudes from the main body and is used to press the ball.

[0124] In some embodiments, the replaceable spray arm 700 includes at least one spray pipe 720. The spray pipe 720 is located above the second bowl 500.

[0125] The spray pipe 720 has a second inner cavity that communicates with the first inner cavity. The spray pipe 720 also has multiple spaced-apart spray holes 721 that communicate with both the second inner cavity and the cleaning chamber. This arrangement of the spray pipe 720 and multiple spray holes 721 increases the spray range and improves the cleaning effect.

[0126] In some embodiments, the axial directions of the spray holes 721 on the same spray pipe 720 have an included angle. For example, the axial directions of each spray hole 721 have an included angle, or the axial directions of two adjacent spray holes 721 have an included angle, or the axial directions of at least two spray holes 721 have an included angle.

[0127] In some embodiments, the number of spray pipes 720 is at least two, and the at least two spray pipes 720 are arranged at circumferential intervals along the main body 710. Exemplarily, the number of spray pipes 720 may be two or three, etc.

[0128] Referring to Figures 5 to 7, in some embodiments, the replaceable spray arm 700 includes a first connector 730, which is connected to the main body 710 and is located on the side of the main body 710 facing the water supply system 200. The water supply system 200 is provided with a second connector that matches the first connector 730, and the first connector 730 engages with the second connector.

[0129] Understandably, by setting the first connector 730 and the second connector 230, the replaceable spray arm 700 is fixed to the water supply system 200, making it less likely for the replaceable spray arm 700 to fall off and ensuring high reliability of the connection.

[0130] Specifically, the first connector 730 includes a flat plate portion 731 and at least two claw portions 732. The flat plate portion 731 is connected to the main body portion 710, and the claw portions 732 are disposed on the side of the flat plate portion 731 opposite to the main body portion 710. At least two claw portions 732 are disposed on opposite sides of the flat plate portion 731 along its extending direction. The claw portions 732 are used to engage with the second connector 230. The second connector 230 may include a groove that matches the claw portions 732. The claw portions 732 are connected to the groove. Alternatively, the second connector 230 may be a raised retaining edge disposed on opposite sides of the water supply pipe 220 along the extending direction of the flat plate portion 731, and the claw portions 732 are connected to the retaining edge. The extending direction of the flat plate portion 731 is the direction shown by the X-axis in Figure 5.

[0131] In some embodiments, the first connector 730 and the main body 710 are integrally formed. For example, they are integrally formed by welding or injection molding. In some embodiments, the second connector 230 is integrally formed with the water supply pipe 220. Alternatively, the second connector 230 and the water supply pipe 220 are separate, and the first connector 730 and the second connector 230 are connected to clamp the water supply pipe 220.

[0132] Referring to Figures 5 to 7, in some embodiments, the replaceable spray arm 700 further includes a handle 740, which is connected to the main body 710 and located on the side of the main body 710 opposite to the first connector 730. It is understood that by providing the handle 740, the user can easily disengage the first connector 730 and the second connector 230 by pulling the handle 740. The user can also easily press the handle 740 to engage the first connector 730 and the second connector 230.

[0133] Specifically, the handle 740 is disc-shaped. The handle 740 is integrally formed with the main body 710.

[0134] In some embodiments, the orthographic projection of the main body 710 onto the plane containing the rear wall of the housing lies within the orthographic projection of the handle 740 onto the plane containing the rear wall of the housing. This allows the handle 740 to be larger, facilitating user operation. The plane containing the rear wall is the plane formed by the X-axis and Z-axis in Figure 1.

[0135] Referring to Figures 1 and 2, in some embodiments, the first bowl basket 300 includes a bowl basket body 310. The bowl basket body 310 is used to hold tableware.

[0136] In some embodiments, the first basket 300 includes two roller assemblies 320. The roller assemblies 320 are used to reduce friction and facilitate user movement of the first basket 300.

[0137] The two roller assemblies 320 are located on both sides of the basket body 310 along the width direction of the box. The width direction of the box is the direction shown by the X-axis in Figure 1.

[0138] Figure 8 is a magnified view of part B in Figure 1.

[0139] Referring to Figures 1 and 8, in some embodiments, the inner wall of the box is provided with two guide rail assemblies 800. The two guide rail assemblies 800 are arranged opposite each other along the width direction of the box, and two roller assemblies 320 are detachably connected to the two guide rail assemblies 800 one-to-one. The guide rail assemblies 800 are movably connected to the box, and the extension direction of the guide rail assemblies 800 is consistent with the depth direction of the box. Thus, when the first bowl basket 300 needs to be disassembled, the bowl basket body 310 can be pulled outwards. The bowl basket body 310 drives the guide rail assemblies 800 to slide outwards via the roller assemblies 320, and then the roller assemblies 320 of the first bowl basket 300 can be removed from the guide rail assemblies 800. Disassembly can be performed from the outside of the box, providing ample space for user operation and high convenience.

[0140] It should be noted that when the first basket 300 is held in place, the user pulls the basket body 310 outward, causing the basket body 310 to slide outward relative to the box along the depth direction of the box via the roller assembly 320. When the user pushes the basket body 310 inward, the basket body 310, through the roller assembly 320, causes the guide rail assembly 800 to slide inward relative to the box along the depth direction of the box. Specifically, the basket body 310, through the roller assembly 320, causes the track 810, stop 830, and limiting member 840 in the guide rail assembly 800 to slide.

[0141] Figure 9 is a schematic diagram of the first state of the guide rail assembly in the dishwasher provided in the embodiment of this application.

[0143] The extension direction of track 810 is consistent with the depth direction of the box.

[0144] The track 810 is provided with a guide cavity 811, the extension direction of which is consistent with the extension direction of the track 810. The roller assembly 320 is partially located within the guide cavity 811. The roller assembly 320 can roll relative to the track 810.

[0145] The track 810 has a first opening 812 on one side along the width direction of the housing, and the first opening 812 communicates with the guide cavity 811. The extension direction of the first opening 812 is consistent with the extension direction of the guide cavity 811.

[0146] The track 810 has a second opening 813 at one end along the extension direction, and the second opening 813 is connected to the guide cavity 811.

[0147] In some embodiments, the guide rail assembly 800 includes a plurality of limiting wheels 820. The limiting wheels 820 are used for rolling connection with the rail 810.

[0148] The limiting wheel 820 is connected to the housing. The limiting wheel 820 can rotate relative to the housing. The axis of the limiting wheel 820 extends in the same direction as the width direction of the housing. The width direction of the housing is the direction shown by the X-axis in Figure 1.

[0149] Specifically, the limiting wheel 820 is located at the bottom and top of the track 810, and the track 810 is tactilely connected to the limiting wheel 820.

[0150] For example, there are four limiting wheels 820. Two limiting wheels 820 are spaced apart at the top of the track 810. Two limiting wheels 820 are spaced apart at the bottom of the track 810.

[0151] In some embodiments, the guide rail assembly 800 includes a stop 830. The stop 830 is used to open or close the second opening 813.

[0152] Among them, the stop 830 is close to the second opening 813 and close to the door body.

[0153] The stop 830 is rotatably connected to the track 810. The stop 830 rotates relative to the track 810 to be located at one end of the track 810 along the depth direction toward the door or on the side of the track 810 along the width direction away from the basket body 310, so as to close or open the second opening 813.

[0154] When the first basket 300 needs to be disassembled, rotate the stop 830 so that the stop 830 is located on the side of the track 810 away from the basket body 310 along the width direction of the box, thereby opening the second opening 813. Pull the basket body 310 outward, and the basket body 310 and the roller assembly 320 move relative to the track 810, thereby allowing the first basket 300 to be removed.

[0155] When the first bowl basket 300 needs to be installed, rotate the stop 830 so that it is located on the side of the track 810 away from the bowl basket body 310 along the width direction of the box, thereby opening the second opening 813. Push the bowl basket body 310 inward, and the bowl basket body 310 and the roller assembly 320 move relative to the track 810, so that the first bowl basket 300 can be installed in the track 810. Then, rotate the stop 830 so that it is located at the end of the track 810 along the depth direction facing the door, thereby closing the second opening 813, and the installation of the first bowl basket 300 is completed.

[0156] Specifically, the inner top wall of the stop member 830 is provided with a first rotating shaft, and the inner bottom wall of the stop member 830 is provided with a second rotating shaft. The top of the track 810 is provided with a first rotating hole, and the first rotating shaft is inserted into the first rotating hole. The bottom of the track 810 is provided with a second rotating hole, and the second rotating shaft is inserted into the second rotating hole.

[0157] Referring to Figures 9 and 11, in some embodiments, the guide rail assembly 800 includes a limiting member 840. The limiting member 840 is used to restrict the position of the roller assembly 320 so that the roller assembly 320 is not easily dislodged from the rail 810.

[0158] A third opening is provided at one end of the track 810 away from the stop member 830, and the third opening communicates with the guide cavity. A limiting member 840 is provided at one end of the track 810 away from the stop member 830 to close the third opening.

[0159] For example, the limiting member 840 can be snapped into the track 810, or the limiting member 840 can be connected to the track 810 by fasteners such as screws.

[0160] Referring to Figures 1 and 2, in some embodiments, the first spray arm 400 is connected to the basket body 310. The first spray arm 400 is located at the bottom of the basket body 310.

[0161] The dish basket body 310 drives the first spray arm 400 to move away from the door body, and the first dish basket 300 moves to its extreme position. In this position, the first spray arm 400 can be inserted into the water supply system 200, allowing communication between them. For example, in the extreme position, the limiting member 840 can abut against the rear wall of the inner liner 100.

[0162] After the door is closed, the door can contact the front of the bowl basket body 310, and the door can apply force to the bowl basket body 310 to ensure the reliability of the connection between the first spray arm 400 and the water supply system 200.

[0163] When the door opens to open the cleaning chamber, the first dish basket 300 moves the first spray arm 400 toward the door, disengaging the first spray arm 400 from the water supply system 200. This makes the removal of the first spray arm 400 and the connection between the first spray arm 400 and the water supply system 200 more convenient and easier to operate.
