[0007] a door body connected to the box body to open and close the washing chamber;

[0008] A bowl basket is located in the washing chamber; the bowl basket includes:

[0009] a bottom wall, wherein a plurality of through holes are arranged on the bottom wall;

[0010] Side walls are fixed to the bottom wall; the side walls and the bottom wall together enclose a cleaning chamber with an opening at the top;

[0011] The spray arm is integrally formed on the bottom surface of the bottom wall. The spray arm and the bottom wall together enclose a spray cavity, and the spray cavity is connected to at least a portion of the through hole.

[0012] The dishwasher basket of the present invention is constructed with a bottom wall and side walls, forming a top-open cleaning chamber. Water is inletted through holes in the bottom wall. Compared to existing basket structures, the side walls of the present invention lack hollowed-out structures, making it easier to clean small items. The spray arm of the present invention is integrally formed with the bottom surface of the bottom wall and, together with the bottom wall, forms the spray chamber. This ensures a reliable and stable connection between the spray arm and the basket, reducing the possibility of water leakage. Furthermore, the spray arm and the bottom wall create a larger spray area, enhancing cleaning efficiency.

[0013] In some embodiments of the present application, the spray arm includes:

[0024] In some embodiments of the present application, the bowl basket further includes an overflow structure, and the overflow structure connects the cleaning chamber and the washing chamber.

[0025] The bowl basket of the embodiment of the present application is provided with an overflow structure so that excess water in the cleaning chamber can overflow into the washing chamber through the overflow structure, thereby reducing the excess water in the cleaning chamber from overflowing into other chambers and causing mutual contamination, thereby affecting the cleaning effect.

[0026] In some embodiments of the present application, the overflow structure includes an overflow panel provided on the bottom wall, and the overflow panel and the bottom wall together enclose an overflow cavity;

[0027] The overflow chamber is in communication with at least two of the sub-chambers;

[0028] An overflow port is provided on the bottom wall of the overflow cavity.

[0029] The present embodiment utilizes an overflow panel on the bottom wall to form an overflow structure. This not only simplifies the structure, but also allows the overflow chamber formed by the overflow panel to communicate with at least two sub-chambers, simplifying the structure of the bowl basket. Furthermore, an overflow port is provided on the bottom wall of the overflow chamber, allowing water within the overflow chamber to be discharged directly into the washing chamber through the overflow port. This simplifies the structure and eliminates the need for additional, complex communication structures.

[0030] In some embodiments of the present application, the height of the overflow structure is lower than the height of the partition plate.

[0031] The embodiment is configured in this way so that the washing water in the sub-chamber overflows through the overflow structure, thereby preventing the washing water from overflowing from the partition plate to other sub-chambers and contaminating each other.

[0032] In some embodiments of the present application, a water tank is formed in the washing chamber, and the water tank is connected to the overflow structure;

[0033] A water level sensor is provided in the water tank, and the water level sensor is configured to detect the water level height in the water tank.

[0066] Dishwasher baskets are located within the dishwasher's interior to hold dishes, cookware, and other items to be washed. Existing baskets have large gaps to ensure a large contact area between the items being washed and the water flow, ensuring a good cleaning effect. However, these baskets are not suitable for washing small items.

[0067] Some dishwashers include an additional cleaning rack that can be placed inside the basket to clean smaller items. However, the cleaning rack lacks stability and can only be rinsed from the top, with water overflowing from the small hole at the bottom, resulting in poor cleaning performance. Furthermore, it cannot perform immersion cleaning.

[0068] In view of this, an embodiment of the present application provides a dishwasher, whose bowl basket includes a bottom wall and a side wall arranged on the bottom wall. The bottom wall is provided with a through hole to achieve water inlet and overflow; the side wall has no hollow structure, which is convenient for cleaning small-sized items.

[0069] Furthermore, a spray arm is integrally formed on the bottom wall of the basket. Together, the spray arm and the bottom wall form a spray chamber that sprays water into the basket. Compared to separate sprayers, the integral formation of the basket and spray arm allows for a larger spray area, facilitating the spraying and cleaning of different areas. Furthermore, the connection between the basket and the spray arm is simplified, ensuring a reliable connection.

[0070] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0071] An embodiment of the present application provides a dishwasher, which may be a cabinet dishwasher, a tabletop dishwasher, a sink-integrated dishwasher, etc.

[0072] Combine Figure 1 and Figure 2 The washing machine comprises a housing 100, which is structured to form a washing chamber 101 for accommodating tableware, cooking utensils or articles to be washed.

[0073] In some embodiments, the cabinet 100 may include a housing that serves as an outer shell of the dishwasher.

[0074] In some embodiments, the housing 100 includes an inner container, which is disposed within the housing. The inner container forms a washing chamber 101. An installation cavity is formed between the inner container and the housing for installing the water inlet structure, drainage structure, etc. of the dishwasher.

[0075] The dishwasher according to the embodiment of the present application may include a door 200 , which is connected to the housing 100 and is used to open and close the washing chamber 101 .

[0076] Illustratively, the door 200 is hinged to the housing 100 so that the door 200 can rotate relative to the housing 100 to open or close the washing chamber 101 .

[0077] A sealing structure is provided between the door body 200 and the box body 100. For example, a door liner is provided on the door body 200, and / or a door seal is provided at the opening edge of the washing chamber 101 of the box body 100. The door liner and the door seal are both sealing structures to improve the sealing performance between the door body 200 and the box body 100 and reduce the possibility of water leakage at the door body 200.

[0078] In some embodiments, as Figure 1As shown, the washing chamber 101 opens forward, and the bottom end of the door 200 is rotatably connected to the bottom end of the housing 100 to open or close the washing chamber 101. The directional word "front" here refers to the side of the dishwasher facing the user.

[0079] In other embodiments, Figure 2 As shown, the washing chamber 101 is opened upward, the rear end of the door body 200 is rotatably connected to the box body 100, and the door body 200 is rotated upward to open the washing chamber 101.

[0080] Combine Figure 3 The dishwasher of the embodiment of the present application may include a bowl basket 300, which is located in the washing chamber 101. The bowl basket 300 is used to hold items to be washed, including tableware, cooking utensils, food, etc.

[0081] In some embodiments, the basket 300 is configured to form a washing chamber 330 for accommodating items to be washed.

[0082] In other embodiments, the basket 300 is configured to form multiple cleaning chambers 330, allowing different items to be cleaned simultaneously. The multiple cleaning chambers 330 can be arranged in various configurations, such as being arranged side by side along the length of the basket 300 or being arranged in a rectangular matrix.

[0083] In some embodiments of the present application, the dishwasher includes a spray portion 412 , which is used to spray water into the washing chamber 101 to clean items.

[0084] In some embodiments, the spraying portion 412 includes a plurality of sprayers to facilitate spray cleaning of the items from different angles, thereby improving the cleaning effect.

[0085] Exemplarily, part of the sprayers sprays the articles from top to bottom, and this part of the sprayers can be called upper sprayers.

[0086] Exemplarily, some of the sprayers spray the articles from bottom to top, and these sprayers can be called lower sprayers.

[0087] In the embodiment of the present application, the items in the bowl basket 300 can be sprayed by the upper sprayer, and the items in the bowl basket 300 can also be sprayed and cleaned by the lower sprayer.

[0088] In some embodiments of the present application, the dishwasher may further include a water diverter valve 500 , a water inlet of the water diverter valve 500 being connected to a water supply component 600 of the dishwasher, and the water diverter valve 500 being configured to distribute wash water toward a plurality of sprayers.

[0089] Continue to refer to Figure 3In some embodiments of the present application, a plurality of through holes 311 are provided on the bottom wall 310 of the cleaning chamber 330 for allowing water to flow into the cleaning chamber 330 .

[0090] The through hole 311 may be a circular hole for easy processing.

[0091] The through holes 311 can be arranged in various ways. For example, the through holes 311 are arranged in a rectangular matrix; for another example, the through holes 311 are arranged in a circular matrix; for another example, the through holes 311 are arranged to form an irregular pattern.

[0092] The diameter of the through hole 311 can be smaller, for example, the diameter of the through hole 311 can be 5.2 mm. This is not a limitation on the size of the diameter of the through hole 311.

[0093] When there are multiple cleaning chambers 330, the diameter of the through hole 311 provided on the bottom wall 310 of each cleaning chamber 330 can be different. For example, the diameters of the through holes 311 of the multiple cleaning chambers 330 can increase sequentially to facilitate cleaning of items of different sizes.

[0094] In some embodiments of the present application, the dishwasher further includes a spray arm 400 , which is located at the bottom of the bowl basket 300 . The spray arm 400 and the bowl basket 300 together form a lower sprayer that sprays water toward the washing chamber 330 .

[0095] In some embodiments, the spray arm 400 is integrally formed with the bottom wall 310 of the bowl basket 300. For example, the spray arm 400 and the bowl basket 300 are integrally injection molded, so that the connection between the spray arm 400 and the bowl basket 300 is reliable and stable, reducing the possibility of water leakage.

[0096] In some embodiments, the spray arm 400 is welded to the bottom wall 310 of the basket 300 to form an integrated structure. This not only ensures a reliable connection between the spray arm 400 and the basket 300, but also simplifies the molds for forming the spray arm 400 and the basket 300, thereby reducing mold development costs.

[0097] In the embodiment of the present application, the spray arm 400 and the bottom wall 310 of the bowl basket 300 form an integrated structure, which not only stabilizes the connection between the spray arm 400 and the bowl basket 300 and reduces the possibility of water leakage; it also forms a larger spraying area at the bottom of the bowl basket 300, which is conducive to improving the cleaning effect.

[0098] like Figure 3 As shown, the spray arm 400 and the bowl basket 300 together enclose a spray chamber 401 , so that the washing water of the water supply component 600 can enter the cleaning chamber 330 through the spray chamber 401 .

[0099] exist Figure 3In the illustrated structure, the spray arm 400 and the bottom wall 310 of the basket 300 together enclose a spray chamber 401. This is not restrictive; at least a portion of the spray arm 400 can extend to the side wall of the basket 300 and enclose the side wall of the basket 300 to form the spray chamber 401, thereby forming a three-dimensional spray water curtain within the washing chamber 330 and improving the washing effect.

[0100] The spray chamber 401 is in communication with at least a portion of the through holes 311 , so that the washing water in the spray chamber 401 can enter the cleaning chamber 330 through the through holes 311 to clean the items in the cleaning chamber 330 .

[0101] In some embodiments of the present application, the bottom wall 310 of the bowl basket 300 forms the bottom wall 310 of the washing chamber 330, and at least part of the through holes 311 are set on the bottom wall 310 forming the washing chamber 330, so that the spray chamber 401 is connected to the washing chamber 330 through at least part of the through holes 311.

[0102] In some embodiments, the through holes 311 are all disposed on the bottom wall 310 forming the cleaning chamber 330 , which can increase the total spraying area communicating between the spray chamber 401 and the cleaning chamber 330 , thereby improving the cleaning effect.

[0103] When the basket 300 is configured to form multiple washing chambers 330, a through-hole 311 is provided on the bottom wall 310 of each washing chamber 330. A single spray arm 400 may be provided, with the basket 300 and the spray arm 400 collectively enclosing a spray chamber 401. The spray chamber 401 communicates with at least a portion of the through-holes 311 in each washing chamber 330. Thus, a single spray arm 400 is configured to spray wash water into the multiple washing chambers 330.

[0104] In other embodiments, multiple spray arms 400 may be provided, with at least one spray arm 400 provided at the bottom of each cleaning chamber 330. Thus, at least one spray chamber 401 is formed at the bottom of each cleaning chamber 330. The spray chamber 401 communicates with the cleaning chamber 330 via the through hole 311, thereby spraying water in the cleaning chamber 330. In this case, each spray arm 400 may communicate with the water supply component 600 via the water diversion valve 500.

[0105] In this way, the water diversion valve 500 can be used to control each cleaning chamber 330 to flow water for cleaning separately, thereby reducing unnecessary waste of water resources.

[0106] Continue to refer to Figures 4 to 7 In some embodiments, the bowl basket 300 may include a bottom wall 310 for supporting items to be washed. The bottom wall 310 is provided with a plurality of through holes 311 .

[0107] In some embodiments, the bowl basket 300 may include side walls 320 fixed to the bottom wall 310 and located at the edge of the bottom wall 310. The side walls 320 and the bottom wall 310 together enclose a washing chamber 330 with an open top.

[0108] In some possible implementations, the bottom wall 310 is rectangular, and the side walls 320 include two first side walls 321 and two second side walls 322. The two first side walls 321 are spaced apart along the transverse direction of the bottom wall 310, and the two second side walls 322 are spaced apart along the longitudinal direction of the bottom wall 310. In this way, a rectangular cleaning chamber 330 is formed.

[0109] In this embodiment of the present application, the bottom wall 310 of the basket 300 is provided with a through-hole 311, which allows water to enter the cleaning chamber 330. The side walls 320 are not hollowed out, which prevents items from falling and allows for cleaning of small items. Furthermore, the basket 300 of this embodiment of the present application can also be used to immerse items for cleaning, thereby improving cleaning efficiency.

[0110] In some embodiments of the present application, the bowl basket 300 may be made of metal, which has a stable structural strength.

[0111] In other embodiments of the present application, the bowl basket 300 may be made of food-grade plastic. The spray arm 400 may also be made of plastic, so that the spray arm 400 and the bowl basket 300 form an integrated structure.

[0112] In some embodiments, the bowl basket 300 further includes rollers 360 mounted on the bottom wall 310 of the bowl basket 300. A plurality of rollers 360 are provided, and the plurality of rollers 360 are arranged at intervals along the longitudinal direction of the bottom wall 310 to form a roller 360 group.

[0113] There are two sets of rollers 360 , one at each end of the bottom wall 310 , thereby forming a stable support at the bottom of the bowl basket 300 .

[0114] The bowl basket 300 of the embodiment of the present application is provided with a plurality of rollers 360 on the bottom wall 310, so that a gap is formed between the bowl basket 300 and the bottom wall of the washing chamber 101. This not only reserves an accommodation space for the spray arm 400, but also prevents the bowl basket 300 from contacting the bottom wall of the washing chamber 101 over a large area and thus preventing water accumulation.

[0115] Continue to refer to Figure 4 and Figure 5 In some embodiments, the bowl basket 300 may further include a partition plate 350 , which is disposed in the washing chamber 330 to divide the washing chamber 330 into at least two sub-chambers 331 .

[0116] The bottom end of the partition plate 350 is connected to the bottom wall 310 to divide the cleaning chamber 330 into a plurality of sub-chambers 331 .

[0117] The bowl basket 300 of the present embodiment is provided with a partition plate 350, which divides the washing chamber 330 into at least two sub-chambers 331, so that the bowl basket 300 can be used to wash different types of items simultaneously. For example, one sub-chamber 331 can be used to wash fruit, and the other sub-chamber 331 can be used to wash seafood.

[0118] The partition plate 350 may extend in the transverse direction of the basket 300 , thereby dividing the washing chamber 330 into at least two sub-chambers 331 arranged side by side in the longitudinal direction.

[0119] The partition plate 350 may extend in the longitudinal direction of the basket 300 to divide the washing chamber 330 into at least two sub-chambers 331 arranged side by side in the transverse direction.

[0120] like Figure 4 and Figure 5 As shown, a plurality of partition plates 350 are provided, at least one partition plate 350 extending in the transverse direction and at least one partition plate 350 extending in the longitudinal direction. The longitudinally extending partition plates 350 intersect with the transversely extending partition plates 350, thereby forming a plurality of sub-chambers 331, which are arranged in a matrix.

[0121] In some embodiments, the height of the partition plate 350 may be less than or equal to the height of the side wall 320 , so as to avoid the partition plate 350 being too high and interfering with other components in the dishwasher.

[0122] In other embodiments, the height of the partition plate 350 can be greater than the height of the side wall 320, so that when there is too much cleaning water in the sub-chamber 331, it can overflow into the washing chamber 101 through the side wall 320, thereby reducing the overflow of water between two adjacent sub-chambers 331 and causing mutual contamination.

[0123] Each sub-chamber 331 is provided with a through hole 311 , so that each sub-chamber 331 can be sprayed for cleaning.

[0124] In some embodiments, only one spray arm 400 may be provided. In this way, the spray chamber 401 formed by the spray arm 400 and the bottom wall 310 sprays water into the multiple sub-chambers 331 at the same time. This simplifies the structure of the dishwasher.

[0125] In other embodiments, multiple spray arms 400 may be provided, with at least one spray arm 400 disposed below each sub-chamber 331. At least one spray chamber 401 is formed below each sub-chamber 331, allowing each sub-chamber 331 to independently control spraying, thereby increasing cleaning flexibility and reducing water waste.

[0126] Continue to refer to Figure 3 In some embodiments, the bowl basket 300 may further include an overflow structure 340 , which connects the cleaning chamber 330 and the washing chamber 101 .

[0127] Such arrangement allows the washing water in the washing chamber 330 to overflow into the washing chamber 101 through the overflow structure 340 .

[0128] When the washing chamber 330 is configured to form a plurality of sub-chambers 331, each sub-chamber 331 may be provided with an overflow structure 340 so that each sub-chamber 331 can independently overflow water into the washing chamber 101. Alternatively, the plurality of sub-chambers 331 may share a single overflow structure 340, thereby simplifying the structure of the bowl basket 300.

[0129] In some embodiments, the overflow structure 340 can be an overflow hole provided on the side wall 320. Since the bowl basket 300 is provided in the washing chamber 101, the overflow hole of the washing bucket in the washing chamber 330 overflows into the washing chamber 101, which has a simple structure.

[0130] In other embodiments, continue to refer to Figure 4 and Figure 5 The overflow structure 340 includes an overflow panel 341 disposed on the bottom wall 310 , and the overflow panel 341 and the bottom wall 310 together enclose an overflow cavity 342 .

[0131] The cross-sectional shape of the overflow panel 341 can be circular, rectangular, etc.

[0132] The overflow chamber 342 is in communication with the washing chamber 330. For example, the top of the overflow panel 341 is open, allowing the overflow chamber 342 to communicate with the washing chamber 330. Alternatively, the overflow panel 341 may be provided with an overflow hole 343, allowing the overflow chamber 342 to communicate with the washing chamber 330. With this arrangement, the height of the overflow hole 343 can be adjusted to determine the water level within the washing chamber 330 for immersion washing.

[0133] An overflow port 344 is provided on the bottom wall 310 in the overflow chamber 342 , so that the overflow chamber 342 is connected to the washing chamber 101 through the overflow port 344 , so that water in the overflow chamber 342 enters the washing chamber 101 through the overflow port 344 .

[0134] In some embodiments, the overflow chamber 342 communicates with at least two sub-chambers 331, such that the two sub-chambers 331 share a single overflow chamber 342. This simplifies the structure of the basket 300 and reduces the area occupied by the overflow chamber 342 on the bottom wall 310 of the basket 300, thereby creating a larger washing volume within the basket 300.

[0135] Exemplarily, the overflow plate 341 is disposed on the partition plate 350 between two adjacent sub-chambers 331 , and at least two overflow holes 343 are provided on the overflow plate 341 . The two sub-chambers 331 are connected to the overflow cavity 342 through at least one overflow hole 343 .

[0136] For example, the overflow panel 341 is disposed at the intersection of the two intersecting partitions 350, and the overflow chamber 342 is connected to the four sub-chambers 331. This helps further simplify the structure of the bowl basket 300 and reduce the area occupied by the overflow chamber 342 on the bottom wall 310 of the bowl basket 300.

[0137] In some embodiments, the height of the overflow structure 340 is lower than that of the partition plate 350. This configuration allows the wash water in the sub-chamber 331 to overflow through the overflow structure 340, preventing overflow from the partition plate 350 to other sub-chambers 331 and contamination.

[0138] The height of the overflow structure 340 refers to the dimension of the overflow structure 340 in a direction perpendicular to the bottom wall 310 . The height of the partition plate 350 refers to the dimension of the partition plate 350 in a direction perpendicular to the bottom wall 310 .

[0139] Continue to refer to Figure 3 In some embodiments, a water tank 110 is formed in the washing chamber 101 , and the water tank 110 is connected to the overflow structure 340 .

[0140] For example, the bottom wall 310 of the washing chamber 101 is recessed downward to form a sink 110. The sink 110 can be vertically opposite to the overflow port 344 of the overflow structure 340, thereby connecting the sink 110 and the overflow structure 340, which is simple in structure.

[0141] A water level sensor 120 is provided in the water tank 110 , and the water level sensor 120 is configured to detect the water level in the water tank 110 .

[0142] When the water level in the water tank 110 detected by the water level sensor 120 reaches a set height, the water level sensor 120 sends a water level signal to the dishwasher controller, causing the dishwasher controller to issue an alert. Furthermore, the dishwasher controller can be configured to control the dishwasher's water supply component 600 to shut down when the water level in the water tank 110 reaches the set height, stopping the flow of water into the washing chamber 330. This not only saves water but also prevents excessive water from washing smaller items out of the basket 300.

[0143] In some embodiments, the water tank 110 is further connected to a drainage structure configured to drain the water in the water tank 110 .

[0144] Combine Figures 8 to 10 In some embodiments, the spray arm 400 may include a main body 410 , the main body 410 being opposite to the bottom wall 310 and spaced apart from each other to form a spray chamber 401 .

[0145] In some embodiments, the spray arm 400 may include a connecting portion 420 , which is disposed at an edge of the main body 410 and is welded to the bottom wall 310 .

[0146] In this way, the spray arm 400 of the embodiment of the present application is provided with a main body 410 and a connecting part 420, and the connecting part 420 is welded to the bottom wall 310, so that the spray arm 400 and the bowl basket 300 form an integrated structure, and the connection method is stable and reliable; the main body 410 and the connecting part 420 enable the spray arm 400 to form a cavity structure with an open top, which is convenient for enclosing with the bottom wall 310 to form a spray cavity 401, and there is no need to provide a cavity structure on the bottom wall 310, which is conducive to simplifying the structure of the bowl basket 300.

[0147] Of course, in some embodiments, a groove may be provided on the bottom surface of the bottom wall 310 , with the opening of the groove facing downward, and the groove and the spray arm 400 together enclose a spray chamber 401 .

[0148] Continue to refer to Figure 8 and Figure 10 In some embodiments, the connecting portion 420 includes a first flange 421 provided on the main body 410 , and the first flange 421 is provided and welded to the bottom wall 310 , so that the welding operation of the spray arm 400 and the bottom wall 310 is convenient.

[0149] The connecting portion 420 may include a second flange 422 . The first flange 421 is taller than the second flange 422 , and the first flange 421 is closer to the edge of the main body 410 than the second flange 422 .

[0150] The connection portion 420 of the present embodiment is welded to the bottom wall 310 by providing a first flange 421. The second flange 422 improves the structural strength of the edge of the main portion 410 and enhances the stability of the weld. Furthermore, the second flange 422 forms a water-retaining structure on the inner side of the weld, reducing the probability of direct contact between water and the weld, thereby ensuring the stability of the weld. Furthermore, the multi-layer flange design of the connection portion 420 helps disperse and relieve thermal stress, reducing deformation and stress concentration at the weld, and reducing the possibility of deformation of the main portion 410.

[0151] In some embodiments, the connecting portion 420 may further include a third flange 423 disposed on the main body 410 . The third flange 423 is located on the side of the first flange 421 away from the second flange 422 . The third flange 423 serves to improve the structural strength of the spray arm 400 .

[0152] Combine Figure 8 and Figure 9 In some embodiments, the main body 410 includes a water inlet 411, which can be tubular to facilitate connection of the water inlet 411 to a pipeline. In some embodiments of the present application, the water inlet 411 is connected to the water diversion valve 500 through a pipeline.

[0153] The main body 410 may include a spray portion 412 , which is connected to the water inlet 411 . The spray portion 412 is opposite to the portion of the bottom wall 310 where the through hole 311 is provided, so as to facilitate water inflow into the cleaning chamber 330 .

[0154] In some embodiments, multiple spray parts 412 are provided, and the multiple spray parts 412 are arranged at intervals around the water inlet 411, and the multiple spray parts 412 are all connected to the water inlet 411. Such an arrangement can simultaneously supply water to multiple locations of the cleaning chamber 330, which is beneficial to the water inlet rate.

[0155] When the cleaning chamber 330 is constructed to form a plurality of sub-chambers 331 , the plurality of spraying parts 412 can also simultaneously supply water to the plurality of sub-chambers 331 so as to clean different items respectively.

[0156] Combine Figure 8 In some embodiments, the main body 410 may further include a connecting portion 413 , which connects the water inlet portion 411 and the spray portion 412 , and the projection width of the connecting portion 413 on the bottom wall 310 is smaller than the projection width of the spray portion 412 on the bottom wall 310 .

[0157] The embodiment of the present application is configured in this way, so as to increase the flow rate of water from the water inlet portion 411 into the spray portion 412, thereby facilitating an increase in the spraying speed.

[0158] In some embodiments of the present application, a spray seat is provided on the bottom wall 310 of the washing chamber 101 , and the spray seat is provided with a water inlet channel, which is connected to the water diversion valve 500 through a pipeline.

[0159] The connecting portion 413 of the spray arm 400 is fixed to the spray seat and is connected to the water inlet channel. In this way, the fixed connection between the spray arm 400 and the spray seat can be achieved at the same time, and the communication between the spray chamber 401 and the water inlet channel can also be achieved.

[0160] The connecting portion 413 and the spray seat may be fixedly connected by means of a snap connection, a threaded connection, or the like.

[0161] Combine Figure 3 In some embodiments, the water supply component 600 may have a heating function to heat the cleaning water.

[0162] In some embodiments, the dishwasher further includes a water softening structure for softening water.

[0163] In some embodiments, the external water source passes through the water softening structure, is then heated by the water supply component 600, and then enters the spray arm 400 through the water diversion valve 500 and enters the cleaning chamber 330 through the through hole.

[0164] In some embodiments, the following cleaning methods may be used for cleaning:

[0165] Water at a first temperature is introduced into the basket 300 to soak the items to be washed for a first preset time to clean impurities on the surfaces of the items; then the water in the basket 300 is drained. The water at the first temperature may be room temperature water.

[0166] Water at a second temperature is passed into the bowl basket 300 to soak the items to be washed for a second preset time, and then drained. The water at the second temperature is higher than the water at the first temperature. For example, the water at the second temperature may be 50°C.

[0167] Normal temperature water is introduced into the bowl basket 300 and the items to be washed are soaked for a third preset time before being drained out.

[0168] The first preset duration, the second preset duration, and the third preset duration may be determined according to actual conditions. For example, the first preset duration and the second preset duration may be 5 minutes, and the third preset duration may be 2 minutes.

[0169] In some embodiments of the present application, a drain outlet is provided at the bottom of the cleaning chamber 330 , and the drain outlet is connected to a drain pump through a pipe, so as to achieve drainage in the cleaning chamber 330 .

[0170] In other embodiments of the present application, the water supply component 600 can be a two-way pump, which can be used to both supply water into the cleaning chamber 330 and discharge water from the cleaning chamber 330, that is, the through hole 311 can be used for both water intake and water discharge, which can simplify the structure of the dishwasher.
