Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a dishwasher. Background Art

[0002] Generally, a spray arm is arranged in the dishwasher. Spray holes are formed in the spray arm. The spray arm can spray water out through the spray holes to clean the tableware in the dishwasher.

[0003] In the related art, generally, a spray arm is arranged in the dishwasher, and a rotating shaft is connected to the spray arm to make the spray arm perform a circular motion, so that the water flow sprayed by the spray arm can cover a circular area to clean the tableware in the dishwasher.

[0004] However, the cleaning ability of the water flow sprayed by one spray arm on the tableware is limited. After the dishwasher finishes cleaning the tableware, it is easy to have the problem that the tableware is not cleaned thoroughly. Summary of the Utility Model

[0005] An embodiment of the utility model provides a dishwasher for improving the user experience of using the dishwasher.

[0006] To achieve the above object, in the first aspect of the present application, a dishwasher is provided, which includes a box body, a mounting seat, a first spray arm and a second spray arm. The box body forms a receiving cavity. The mounting seat is arranged in the receiving cavity and is rotatably connected to the box body. The first spray arm is arranged in the receiving cavity. The first spray arm is rotatably connected to the mounting seat. A plurality of first water outlets are formed on the first spray arm. The first spray arm can spray cleaning liquid into the receiving cavity through the plurality of first water outlets. The second spray arm is arranged in the receiving cavity. The second spray arm is rotatably connected to the mounting seat. A plurality of second water outlets are formed on the second spray arm. The second spray arm can spray cleaning liquid into the receiving cavity through the plurality of second water outlets. When the first spray arm rotates, the cleaning liquid sprayed out from the plurality of first water outlets can form a first spraying area. When the second spray arm rotates, the cleaning liquid sprayed out from the plurality of second water outlets can form a second spraying area. A part of the first spraying area coincides with a part of the second spraying area.

[0007] Through the above arrangement, during the working process of the dishwasher, the first spray arm and the second spray arm can rotate simultaneously and spray cleaning liquid to wash the tableware. Since a part of the first spraying area coincides with a part of the second spraying area, the first spray arm and the second spray arm can wash the tableware in the overlapping area more powerfully.

[0008] Moreover, since the mounting base is rotatably connected to the cabinet, during the self-rotation of the first spray arm and the second spray arm relative to the mounting base, the first spray arm and the second spray arm will also revolve around the rotation axis of the mounting base. In this way, the overlapping area can also rotate around the rotation axis of the mounting base, which can increase the number of tableware that can be rinsed in this overlapping area.

[0009] In this way, through the arrangement of the first spray arm, the second spray arm and the mounting base, the dishwasher can rinse most of the tableware in the cabinet with relatively strong force, which can improve the cleaning effect of the dishwasher on the tableware and enhance the user experience of using the dishwasher.

[0010] In some embodiments of the present application, the rotation axis of the first spray arm is the first axis, the rotation axis of the second spray arm is the second axis, the first axis is parallel to the second axis, and the distance between the first axis and the second axis is the first distance. Among the multiple first water outlets, the first water outlet farthest from the first axis is the first boundary water outlet, and the distance between the first boundary water outlet and the first axis is greater than half of the first distance. Among the multiple second water outlets, the second water outlet farthest from the second axis is the second boundary water outlet, and the distance between the second boundary water outlet and the first axis is greater than half of the first distance.

[0011] Through the above arrangement, during the operation of the dishwasher, since the distance between the first boundary water outlet and the first axis is greater than half of the first distance, and the distance between the second boundary water outlet and the first axis is greater than half of the first distance, the cleaning liquid sprayed from the first boundary water outlet can be sprayed into the range of the second spraying area, and the cleaning liquid sprayed from the second boundary water outlet can be sprayed into the range of the first spraying area.

[0012] In this way, through the arrangement of the first boundary water outlet and the second boundary water outlet, partial overlap of the first spraying area and the second spraying area can be achieved, so as to rinse the tableware in this overlapping area more powerfully, thereby improving the cleaning effect of the dishwasher on the tableware.

[0013] In some embodiments of the present application, the extending direction of the first spray arm is perpendicular to the direction of the first axis. And / or, the extending direction of the second spray arm is perpendicular to the direction of the second axis.

[0014] With the above settings, during the rotation of the first spray arm, the first spray arm sprays the cleaning liquid in a fixed direction. In this way, the cleaning liquid sprayed by the first spray arm can be more concentrated on the tableware, so as to ensure the flushing effect of the first spray arm on the tableware, and thus ensure the user experience of using the dishwasher. During the rotation of the second spray arm, the second spray arm sprays the cleaning liquid in a fixed direction. In this way, the cleaning liquid sprayed by the second spray arm can be more concentrated on the tableware, so as to ensure the flushing effect of the second spray arm on the tableware, and thus ensure the user experience of using the dishwasher.

[0015] In some embodiments of the present application, the rotation direction of the first spray arm is opposite to that of the second spray arm, and the rotation speeds of the first spray arm and the second spray arm are the same.

[0016] With the above settings, the cleaning liquid sprayed when the first spray arm rotates will be sprayed onto the tableware along an arc extending in the rotation direction of the first spray arm, and the cleaning liquid sprayed by the second spray arm will be sprayed onto the tableware along an arc extending in the rotation direction of the second spray arm. When the rotation directions of the first spray arm and the second spray arm are the same, for the same tableware, the cleaning liquids sprayed by the first spray arm and the second spray arm will be on opposite sides of the tableware and sprayed onto the tableware from opposite sides of the tableware. Compared with the rotation directions of the first spray arm and the second spray arm being the same, when the rotation direction of the first spray arm is opposite to that of the second spray arm, for the same tableware, the cleaning liquids sprayed by the first spray arm and the second spray arm can be sprayed onto the tableware from the same side of the tableware and then sprayed onto the other side of the tableware, so that the cleaning liquid is more concentrated when cleaning the tableware, so as to perform a more powerful flushing on the tableware, so as to further improve the cleaning effect of the dishwasher on the tableware.

[0017] In some embodiments of the present application, the rotation axes of the first spray arm and the second spray arm are symmetric with respect to the rotation axis of the mounting seat.

[0018] With the above settings, the first spray arm and the second spray arm can apply pressure to the mounting seat on both sides opposite to the rotation axis of the mounting seat, making the force on the mounting seat more balanced. In this way, during the operation of the dishwasher, the mounting seat can rotate more smoothly, so that the stability of the mounting seat, the first spray arm and the second spray arm during rotation can be improved, thereby improving the stability of the dishwasher during operation and ensuring the normal use of the dishwasher.

[0019] In some embodiments of the present application, a plurality of first water outlets are arranged at intervals along the extension direction of the first spray arm. And / or, a plurality of second water outlets are arranged at intervals along the extension direction of the second spray arm.

[0020] With the above settings, along the extending direction of the first spray arm, the first spray arm has a relatively large size, so that more first water outlets can be provided, thereby increasing the water outlet range of the first spray arm and improving the cleaning effect of the cleaning liquid sprayed by the first spray arm on the tableware. Along the extending direction of the second spray arm, the second spray arm has a relatively large size, so that more second water outlets can be provided, thereby increasing the water outlet range of the second spray arm and improving the cleaning effect of the cleaning liquid sprayed by the second spray arm on the tableware.

[0021] In some embodiments of the present application, the dishwasher further includes a first rotating shaft, a second rotating shaft, a driving member, and a transmission assembly. The first rotating shaft is rotatably connected to the mounting seat, and the first spray arm is connected to the end of the first rotating shaft away from the mounting seat. The second rotating shaft is rotatably connected to the mounting seat, and the second spray arm is connected to the end of the second rotating shaft away from the mounting seat. The driving member is connected to the mounting seat and is connected to one of the first rotating shaft and the second rotating shaft to drive one of the first rotating shaft and the second rotating shaft to rotate. The transmission assembly is disposed in the cabinet and is connected to both the first rotating shaft and the second rotating shaft for driving the other one of the first rotating shaft and the second rotating shaft to rotate.

[0022] With the above settings, by driving one of the first rotating shaft and the second rotating shaft to rotate by the driving member, the first spray arm or the second spray arm can be rotated, and by the setting of the transmission assembly, one of the first rotating shaft and the second rotating shaft can drive the other one to rotate synchronously, so as to realize the synchronous rotation of the first spray arm and the second spray arm, thereby cleaning the tableware to realize the cleaning function of the dishwasher on the tableware.

[0023] In some embodiments of the present application, the transmission assembly includes a plurality of gears that mesh with each other. The plurality of gears include a first gear and a second gear. The first gear is sleeved on the first rotating shaft. The second gear is sleeved on the second rotating shaft.

[0024] With the above settings, when the driving member drives the first rotating shaft or the second rotating shaft to rotate, since the plurality of gears are engaged together, the first gear and the second gear can rotate synchronously, so that the first rotating shaft and the second rotating shaft can rotate synchronously, thereby realizing the synchronous rotation of the first spray arm and the second spray arm.

[0025] In some embodiments of the present application, the mounting seat is formed with a water supply cavity for communicating with a water supply device. The first spray arm is formed with a first water outlet cavity, and the first water outlet cavity communicates with a plurality of first water outlets. The first rotating shaft is formed with a first communication channel that communicates the water supply cavity and the first water outlet cavity. And / or, the second spray arm is formed with a second water outlet cavity, and the second water outlet cavity communicates with a plurality of second water outlets. The second rotating shaft is formed with a second communication channel that communicates the water supply cavity and the second water outlet cavity.

[0026] With the above settings, the water supply device can introduce the cleaning liquid into the water supply chamber, and then introduce the cleaning liquid in the water supply chamber into the first water outlet chamber and the second water outlet chamber, and finally spray it out through a plurality of first water outlets and a plurality of second water outlets to wash the tableware.

[0027] Through the setting of the first communication channel, the first water outlet chamber can be directly communicated with the water supply chamber through the first communication channel, so that there is no need to separately set a device for rotating the first spray arm and a device for communicating the first water outlet chamber and the water supply chamber. Through the setting of the second communication channel, the second water outlet chamber can be directly communicated with the water supply chamber through the second communication channel, so that there is no need to separately set a device for rotating the second spray arm and a device for communicating the second water outlet chamber and the water supply chamber. In this way, through the setting of the first rotating shaft and the second rotating shaft, the connection structure between the first spray arm and the mounting seat can be simplified, and the connection structure between the second spray arm and the mounting seat can be simplified, so that the processing of the dishwasher can be facilitated.

[0028] In the second aspect of the present application, a dishwasher is provided, including a box body, a mounting seat, a first spray arm and a second spray arm. The box body forms a receiving cavity. The mounting seat is arranged in the receiving cavity and is rotatably connected to the box body. The first spray arm is arranged in the receiving cavity. The first spray arm is rotatably connected to the mounting seat, and a first water outlet is formed on the first spray arm. The first spray arm can spray the cleaning liquid into the receiving cavity through the first water outlet. The second spray arm is arranged in the receiving cavity. The second spray arm is rotatably connected to the mounting seat, and a second water outlet is formed on the second spray arm. The second spray arm can spray the cleaning liquid into the receiving cavity through the second water outlet. The rotation of the first spray arm can make the cleaning liquid sprayed out from the first water outlet form a first spraying area, and the rotation of the second spray arm can make the cleaning liquid sprayed out from the second water outlet form a second spraying area. Part of the first spraying area coincides with part of the second spraying area.

[0029] The dishwasher provided in the second aspect of the present application can achieve the same beneficial effects as the above technical solutions, so it will not be elaborated here. Description of the Drawings

[0055] With the improvement of people's living standards, dishwashers, as a kind of cleaning equipment for washing tableware, are becoming more and more popular among people. The dishwashing of tableware by a dishwasher is carried out by introducing a cleaning liquid into the tableware inside the dishwasher, so as to wash the tableware with the cleaning liquid.

[0056] Generally, a spray arm is arranged inside the dishwasher. Spray holes are formed on the spray arm. The spray arm can spray water out through the spray holes, and the stains on the tableware inside the dishwasher are washed away by the water flow, so as to wash the tableware.

[0057] In the related art, generally, a spray arm is arranged inside the dishwasher, and a rotating shaft is connected to the spray arm to make the spray arm perform a circular motion, so that the water flow sprayed by the spray arm can cover a circular area, so as to wash the tableware inside the dishwasher.

[0058] However, the cleaning ability of the water flow sprayed by one spray arm on the tableware is limited. After the dishwasher finishes washing the tableware, the problem that the tableware is not cleaned thoroughly is likely to occur.

[0059] Based on this, the present application provides a dishwasher, as Figure 1 shown, the dishwasher 10 includes a cabinet 1, and the cabinet 1 forms a receiving cavity 11. Specifically, the cabinet 1 includes a main body and an inner liner. The inner liner is arranged inside the main body, and the inner liner forms the receiving cavity 11.

[0060] The dishwasher 10 further includes a mounting seat 2. The mounting seat 2 is arranged in the receiving cavity 11 and is rotatably connected to the cabinet 1.

[0061] Exemplarily, as Figure 2 、 Figure 3 shown, the shape of the mounting seat 2 can be rod-shaped or disc-shaped, etc.

[0062] As Figure 3 、 Figure 4 shown, the dishwasher 10 further includes a first spray arm 3 and a second spray arm 4. The first spray arm 3 is arranged in the receiving cavity 11. The first spray arm 3 is rotatably connected to the mounting seat 2. A first water outlet 3B is formed on the first spray arm 3. The first spray arm 3 can spray the cleaning liquid into the receiving cavity 11 through the first water outlet 3B.

[0063] Specifically, a plurality of first water outlets 3B are formed on the first spray arm 3, and the first spray arm 3 can spray cleaning liquid into the accommodation cavity 11 through the plurality of first water outlets 3B.

[0064] The second spray arm 4 is arranged in the accommodation cavity 11. The second spray arm 4 is rotatably connected to the mounting seat 2. A plurality of second water outlets 4B are formed on the second spray arm 4, and the second spray arm 4 can spray cleaning liquid into the accommodation cavity 11 through the plurality of second water outlets 4B.

[0065] Specifically, a plurality of second water outlets 4B are formed on the second spray arm 4, and the second spray arm 4 can spray cleaning liquid into the accommodation cavity 11 through the plurality of second water outlets 4B.

[0066] Rotation of the first spray arm 3 can cause the cleaning liquid sprayed from the plurality of first water outlets 3B to form a first spraying area, and rotation of the second spray arm 4 can cause the cleaning liquid sprayed from the plurality of second water outlets 4B to form a second spraying area. Part of the first spraying area coincides with part of the second spraying area.

[0067] Specifically, as Figure 5 shown, Figure 5 the dotted line O in it is the spraying range when the first spray arm 3 is stationary, Figure 5 and the area R shown in it is the spraying range when the first spray arm 3 rotates, that is, the first spraying area. Figure 5 The dotted line P in it is the spraying range when the second spray arm 4 is stationary, Figure 5 and the area Q shown in it is the spraying range when the second spray arm 4 rotates, that is, the second spraying area. The overlapping area of the first spraying area and the second spraying area is the Figure 5 W area shown in it. When the mounting seat 2 rotates in the direction of the arrow shown in Figure 5 it, the overlapping area will also rotate around the rotation axis of the mounting seat 2.

[0068] Through the above settings, during the operation of the dishwasher 10, the first spray arm 3 and the second spray arm 4 can rotate simultaneously and spray cleaning liquid to rinse the tableware. Since part of the first spraying area coincides with part of the second spraying area, the first spray arm 3 and the second spray arm 4 can rinse the tableware in the overlapping area more powerfully.

[0069] Moreover, since the mounting seat 2 is rotatably connected to the cabinet 1, during the process of the first spray arm 3 and the second spray arm 4 rotating relative to the mounting seat 2, the first spray arm 3 and the second spray arm 4 will also revolve around the rotation axis of the mounting seat 2. In this way, the overlapping area can also rotate around the rotation axis of the mounting seat 2, so that the number of tableware that can be rinsed in the overlapping area can be increased.

[0070] In this way, through the provision of the first spray arm 3, the second spray arm 4 and the mounting seat 2, the dishwasher 10 can perform a relatively strong flushing on most of the tableware in the cabinet 1, so that the cleaning effect of the dishwasher 10 on the tableware can be improved, and the user experience of using the dishwasher 10 can be enhanced.

[0071] In some embodiments, the rotation axes of the first spray arm 3 and the second spray arm 4 are symmetrical with respect to the rotation axis of the mounting seat 2.

[0072] Through the above arrangement, the first spray arm 3 and the second spray arm 4 can apply pressure to the mounting seat 2 on opposite sides of the rotation axis of the mounting seat 2, making the force on the mounting seat 2 more balanced.

[0073] In this way, during the operation of the dishwasher 10, the mounting seat 2 can rotate more smoothly, so that the stability of the mounting seat 2, the first spray arm 3 and the second spray arm 4 during rotation can be improved, thereby enhancing the stability of the dishwasher 10 during operation and ensuring the normal use of the dishwasher 10.

[0074] As Figure 6 shown, the rotation axis of the first spray arm 3 is the first axis M, and the rotation axis of the second spray arm 4 is the second axis N.

[0075] Exemplarily, the first axis M and the second axis N may intersect. For example, as Figure 6 shown, the first spray arm 3 and the second spray arm 4 are located on opposite sides of the rotation axis of the mounting seat 2 ( Figure 6 the dashed line O shown in), and along the direction in which the mounting seat 2 approaches the first spray arm 3 and the second spray arm 4, the distance between the first axis M and the rotation axis of the mounting seat 2 gradually decreases, and the distance between the second axis N and the rotation axis of the mounting seat 2 gradually decreases.

[0076] Exemplarily, as Figure 7 shown, the rotation axis of the first spray arm 3 and the rotation axis of the second spray arm 4 may be parallel.

[0077] Specifically, as Figure 4 、 Figure 7 shown, the distance between the first axis M and the second axis N is the first distance ( Figure 7 the distance L1 shown in).

[0078] Among the multiple first water outlets 3B, the first water outlet 3B farthest from the first axis M is the first boundary water outlet 3B1, and the distance between the first boundary water outlet 3B1 and the first axis M ( Figure 4 the distance L2 shown in) is greater than half of the first distance.

[0079] Specifically, in some embodiments, in a direction perpendicular to the extending direction of the first spray arm 3, a plurality of first water outlets 3B are arranged at intervals in multiple rows.

[0080] In other embodiments, a plurality of first water outlets 3B are arranged at intervals along the extending direction of the first spray arm 3. In this way, along the extending direction of the first spray arm 3, the first spray arm 3 has a relatively large size, so that a relatively large number of first water outlets 3B can be provided, thereby increasing the water outlet range of the first spray arm 3 and improving the cleaning effect of the cleaning liquid sprayed by the first spray arm 3 on the tableware.

[0081] Among the plurality of second water outlets 4B, the second water outlet 4B farthest from the second axis N is the second boundary water outlet 4B1, and the distance between the second boundary water outlet 4B1 and the first axis M ( Figure 4 the distance L3 shown in) is greater than half of the first distance.

[0082] Specifically, in some embodiments, in a direction perpendicular to the extending direction of the second spray arm 4, a plurality of second water outlets 4B are arranged at intervals in multiple rows.

[0083] In other embodiments, a plurality of second water outlets 4B are arranged at intervals along the extending direction of the second spray arm 4. In this way, along the extending direction of the second spray arm 4, the second spray arm 4 has a relatively large size, so that a relatively large number of second water outlets 4B can be provided, thereby increasing the water outlet range of the second spray arm 4 and improving the cleaning effect of the cleaning liquid sprayed by the second spray arm 4 on the tableware.

[0084] Through the above settings, during the operation of the dishwasher 10, since the distance between the first boundary water outlet 3B1 and the first axis M is greater than half of the first distance, and the distance between the second boundary water outlet 4B1 and the first axis M is greater than half of the first distance, the cleaning liquid sprayed from the first boundary water outlet 3B1 can be sprayed into the range of the second spraying area, and the cleaning liquid sprayed from the second boundary water outlet 4B1 can be sprayed into the range of the first spraying area.

[0085] In this way, through the settings of the first boundary water outlet 3B1 and the second boundary water outlet 4B1, partial overlap of the first spraying area and the second spraying area can be achieved, so as to perform more powerful flushing on the tableware in the overlapping area, thereby improving the cleaning effect of the dishwasher 10 on the tableware.

[0086] At the same time, since the first axis M is parallel to the second axis N, when installing the first spray arm 3 and the second spray arm 4, compared with the case where the first axis M and the second axis N are inclined, there can be enough space between the first spray arm 3 and the second spray arm 4, which is convenient for the installation of the first spray arm 3 and the second spray arm 4.

[0087] Exemplarily, the direction of the first axis M may be consistent with the vertical direction. For example, the mounting base 2 is connected to the bottom wall of the accommodating cavity 11, and the first spray arm 3 and the second spray arm 4 are connected above the mounting base 2 for cleaning the tableware located above the mounting base 2.

[0088] Alternatively, the mounting base 2 is connected to the box body 1 through a pipeline and is located in the upper part of the accommodating cavity 11. The first spray arm 3 and the second spray arm 4 are connected below the mounting base 2 for cleaning the tableware located below the mounting base 2.

[0089] Exemplarily, the direction of the first axis M may be consistent with the horizontal direction. For example, the mounting base 2 is connected to the side wall on one side of the accommodating cavity 11, and the first spray arm 3 and the second spray arm 4 are connected to the side away from the side wall of the accommodating cavity 11 on one side of the mounting base 2.

[0090] In some examples, the mounting base 2 is connected to the bottom wall of the box body 1. The first spray arm 3 sprays the cleaning liquid upward in the vertical direction, and the second spray arm 4 sprays the cleaning liquid upward in the vertical direction.

[0091] Through the above settings, the first spray arm 3 and the second spray arm 4 can spray the cleaning liquid upward along the vertical direction to the tableware, so that the cleaning liquid sprayed by the first spray arm 3 and the cleaning liquid sprayed by the second spray arm 4 can cover a larger range to clean more tableware, thereby ensuring the cleaning effect of the dishwasher 10 on the tableware.

[0092] On this basis, in some embodiments, the rotation direction of the first spray arm 3 is the same as the rotation direction of the second spray arm 4.

[0093] In other embodiments, the rotation direction of the first spray arm 3 is opposite to the rotation direction of the second spray arm 4.

[0094] Through the above settings, the cleaning liquid sprayed when the first spray arm 3 rotates will be sprayed onto the tableware along an arc extending in the rotation direction of the first spray arm 3, and the cleaning liquid sprayed by the second spray arm 4 will be sprayed onto the tableware along an arc extending in the rotation direction of the second spray arm 4. When the rotation directions of the first spray arm 3 and the second spray arm 4 are the same, for the same tableware, the cleaning liquid sprayed by the first spray arm 3 and the cleaning liquid sprayed by the second spray arm 4 will be located on opposite sides of the tableware and sprayed onto the tableware from opposite sides of the tableware.

[0095] Compared with the case where the rotation directions of the first spray arm 3 and the second spray arm 4 are the same, when the rotation direction of the first spray arm 3 is opposite to that of the second spray arm 4, for the same tableware, the cleaning liquid sprayed by the first spray arm 3 and the second spray arm 4 can be sprayed onto the tableware from the same side of the tableware and then onto the other side of the tableware, so that the cleaning liquid is more concentrated when cleaning the tableware, so as to perform a more powerful flushing of the tableware, thereby further improving the cleaning effect of the dishwasher 10 on the tableware.

[0096] In some examples, the rotation direction of the first spray arm 3 is opposite to that of the second spray arm 4, and the rotation speed of the first spray arm 3 is the same as that of the second spray arm 4.

[0097] In this way, the first spray arm 3 and the second spray arm 4 will not interfere with each other during rotation, and the first spray arm 3 and the second spray arm 4 will not collide, so that the arrangement of the first spray arm 3 and the second spray arm 4 can be facilitated and the stability of the dishwasher 10 during operation can be ensured.

[0098] Exemplarily, the distance between the first spray arm 3 and the mounting seat 2 can be the same as the distance between the second spray arm 4 and the mounting seat 2.

[0099] Exemplarily, the first spray arm 3 is located on the side of the second spray arm 4 close to the mounting seat 2.

[0100] In this way, during the rotation of the first spray arm 3 and the second spray arm 4, when one of the first spray arm 3 and the second spray arm 4 fails and stops rotating, the second spray arm 4 and the first spray arm 3 will not collide, and the other of the first spray arm 3 and the second spray arm 4 can still continue to rotate normally, so that the safety of the dishwasher 10 during operation can be improved.

[0101] In some embodiments, as Figure 8 shown, the included angle between the extending direction of the first spray arm 3 (the X direction shown in Figure 8 ) and the direction of the first axis M is α, and α is an acute angle.

[0102] In this way, during the rotation of the first spray arm 3, the orientations of the multiple first water outlets 3B will gradually change, the direction of the cleaning liquid sprayed by the first spray arm 3 will gradually change, and the cleaning liquid can be sprayed to a larger range, so that the range of the cleaning liquid sprayed by the first spray arm 3 can be increased.

[0103] In other embodiments, as Figure 9 shown, the extending direction of the first spray arm 3 is perpendicular to the direction of the first axis M.

[0104] With the above settings, during the rotation of the first spray arm 3, the first spray arm 3 will spray the cleaning liquid in a fixed direction. In this way, the cleaning liquid sprayed by the first spray arm 3 can be more concentrated on the tableware, so as to ensure the flushing effect of the first spray arm 3 on the tableware, and thus ensure the user experience of the dishwasher 10.

[0105] In some embodiments, the angle between the extending direction of the second spray arm 4 and the direction of the second axis N is b, and b is an acute angle.

[0106] In this way, during the rotation of the second spray arm 4, the orientations of the multiple second water outlets 4B will gradually change, and the direction of the cleaning liquid sprayed by the second spray arm 4 will gradually change, so that the cleaning liquid can be sprayed over a larger range, thus increasing the spraying range of the cleaning liquid by the second spray arm 4.

[0107] In other embodiments, the extending direction of the second spray arm 4 is perpendicular to the direction of the second axis N.

[0108] With the above settings, during the rotation of the second spray arm 4, the second spray arm 4 will spray the cleaning liquid in a fixed direction. In this way, the cleaning liquid sprayed by the second spray arm 4 can be more concentrated on the tableware, so as to ensure the flushing effect of the second spray arm 4 on the tableware, and thus ensure the user experience of the dishwasher 10.

[0109] In some embodiments, the dishwasher 10 can drive the rotation of the first spray arm 3 by adjusting the spraying angles of the cleaning liquid from the multiple first water outlets 3B and drive the rotation of the second spray arm 4 by adjusting the spraying angles of the cleaning liquid from the multiple second water outlets 4B, using the reaction forces of the cleaning liquid sprayed from the multiple first water outlets 3B and the multiple second water outlets 4B.

[0110] In other embodiments, as Figure 4 shown, the dishwasher 10 further includes a first rotating shaft 7 and a second rotating shaft 8. The first rotating shaft 7 is rotatably connected to the mounting seat 2, and the first spray arm 3 is connected to the end of the first rotating shaft 7 away from the mounting seat 2.

[0111] The second rotating shaft 8 is rotatably connected to the mounting seat 2, and the second spray arm 4 is connected to the end of the second rotating shaft 8 away from the mounting seat 2.

[0112] As Figure 10 shown, the dishwasher 10 further includes a driving member and a transmission assembly 6. The driving member is connected to the mounting seat 2 and is connected to one of the first rotating shaft 7 and the second rotating shaft 8 to drive the rotation of one of the first rotating shaft 7 and the second rotating shaft 8.

[0113] The transmission assembly 6 is disposed in the cabinet 1 and is connected to both the first rotating shaft 7 and the second rotating shaft 8 for driving the rotation of the other one of the first rotating shaft 7 and the second rotating shaft 8.

[0114] Exemplarily, the driving member can be a motor, a hydraulic motor, etc.

[0115] In this way, by driving one of the first rotating shaft 7 and the second rotating shaft 8 to rotate through the driving member, the first spray arm 3 or the second spray arm 4 can be rotated, and through the arrangement of the transmission assembly 6, one of the first rotating shaft 7 and the second rotating shaft 8 can drive the other to rotate synchronously, so as to realize the synchronous rotation of the first spray arm 3 and the second spray arm 4, thereby cleaning the tableware and realizing the cleaning function of the dishwasher 10 for the tableware.

[0116] Exemplarily, the transmission assembly 6 can be structures such as a transmission belt, a transmission wheel, etc., and the first rotating shaft 7 is connected to the second rotating shaft 8 through a transmission belt or a transmission wheel, etc.

[0117] Exemplarily, as Figure 10 , Figure 11 shown, the transmission assembly 6 includes a plurality of gears 61, and the plurality of gears 61 are meshed together. The plurality of gears 61 include a first gear 611 and a second gear 612. The first gear 611 is sleeved on the first rotating shaft 7. The second gear 612 is sleeved on the second rotating shaft 8.

[0118] Through the above arrangement, when the driving member drives the first rotating shaft 7 or the second rotating shaft 8 to rotate, since the plurality of gears 61 are meshed together, the first gear 611 and the second gear 612 can rotate synchronously, so that the first rotating shaft 7 and the second rotating shaft 8 can rotate synchronously, thereby realizing the synchronous rotation of the first spray arm 3 and the second spray arm 4.

[0119] Exemplarily, the number of the plurality of gears 61 can be two, three, four, etc.

[0120] In some examples, the plurality of gears 61 further includes a third gear, and the number of the plurality of gears 61 is three. The third gear is meshed between the first gear 611 and the second gear 612. When the first gear 611 rotates, the first gear 611 can drive the third gear to rotate, so that the third gear drives the second gear 612 to rotate, thereby realizing the synchronous rotation of the first rotating shaft 7 and the second rotating shaft 8.

[0121] In some examples, as Figure 12 shown, the number of the plurality of gears 61 is two, and the two gears 61 are respectively the first gear 611 and the second gear 612. The first gear 611 and the second gear 612 are meshed.

[0122] In this way, the number of the gears 61 in the transmission assembly 6 can be reduced, thereby simplifying the structure of the transmission assembly 6 and facilitating the arrangement of the transmission assembly 6.

[0123] In some examples, the shape and size of the first gear 611 are the same as those of the second gear 612. This can make the rotation speeds of the first spray arm 3 and the second spray arm 4 the same, so that the cleaning liquid sprayed during the rotation of the first spray arm 3 and the cleaning liquid sprayed during the rotation of the second spray arm 4 are staggered from each other, thereby improving the cleaning effect of the dishwasher 10 on tableware.

[0124] In some other embodiments, the dishwasher 10 includes two driving members, and the two driving members are respectively connected to the first rotating shaft 7 and the second rotating shaft 8, and the synchronous rotation of the first spray arm 3 and the second spray arm 4 can also be realized.

[0125] On this basis, in some embodiments, as Figure 13 shown, the mounting seat 2 is formed with a water supply cavity 2A, and the water supply cavity 2A is used to communicate with a water supply device.

[0126] Exemplarily, the water supply device includes a water pump and a water storage tank. The water pump communicates the water storage tank and the water supply cavity 2A, and can continuously pump the water in the water storage tank into the water supply cavity 2A.

[0127] As Figure 13 shown, the first spray arm 3 is formed with a first water outlet cavity 3A, and the first water outlet cavity 3A communicates with a plurality of first water outlet ports 3B. The first rotating shaft 7 is formed with a first communication channel 71, and the first communication channel 71 communicates the water supply cavity 2A and the first water outlet cavity 3A.

[0128] In some examples, as Figure 13 、 Figure 14 shown, the first rotating shaft 7 includes a first sleeve 72 and a second sleeve 73. The first sleeve 72 is connected to the first spray arm 3, and the second sleeve 73 is connected to the mounting seat 2. The first sleeve 72 is sleeved on the second sleeve 73 and is rotatably connected to the second sleeve 73. The second sleeve 73 and the first sleeve 72 are hermetically arranged to form the first communication channel 71.

[0129] As Figure 13 shown, the second spray arm 4 is formed with a second water outlet cavity 4A, and the second water outlet cavity 4A communicates with a plurality of second water outlet ports 4B. The second rotating shaft 8 is formed with a second communication channel 81, and the second communication channel 81 communicates the water supply cavity 2A and the second water outlet cavity 4A.

[0130] In some examples, the second rotating shaft 8 includes a third sleeve and a fourth sleeve. The third sleeve is connected to the second spray arm 4, and the fourth sleeve is connected to the mounting seat 2. The third sleeve is sleeved on the fourth sleeve and is rotatably connected to the fourth sleeve. The third sleeve and the fourth sleeve are hermetically arranged to form the second communication channel 81.

[0131] With the above settings, the water supply device can introduce the cleaning liquid into the water supply chamber 2A, and then introduce the cleaning liquid in the water supply chamber 2A into the first water outlet chamber 3A and the second water outlet chamber 4A, and finally spray it out through a plurality of first water outlets 3B and a plurality of second water outlets 4B to wash the tableware.

[0132] With the setting of the first communication channel 71, the first water outlet chamber 3A can be directly communicated with the water supply chamber 2A through the first communication channel 71. In this way, there is no need to separately set a device for rotating the first spray arm 3 and a device for communicating the first water outlet chamber 3A and the water supply chamber 2A.

[0133] With the setting of the second communication channel 81, the second water outlet chamber 4A can be directly communicated with the water supply chamber 2A through the second communication channel 81. In this way, there is no need to separately set a device for rotating the second spray arm 4 and a device for communicating the second water outlet chamber 4A and the water supply chamber 2A.

[0134] In this way, with the setting of the first rotating shaft 7 and the second rotating shaft 8, the connection structure between the first spray arm 3 and the mounting base 2 can be simplified, and the connection structure between the second spray arm 4 and the mounting base 2 can be simplified. In this way, it is convenient for the processing of the dishwasher 10.

[0135] In some embodiments, as Figure 15 shown, the dishwasher 10 further includes a third rotating shaft 9. The third rotating shaft 9 is rotatably connected to the cabinet 1, and the direction of the rotation axis of the third rotating shaft 9 is the same as the first direction. The end of the third rotating shaft 9 away from the cabinet 1 is connected to the other side of the mounting base 2 in the first direction.

[0136] It can be understood that the third rotating shaft 9 is formed with a third communication channel, and the third communication channel is communicated with both the water supply chamber 2A and the water supply device.

[0137] Exemplarily, the first spray arm 3 can be in a linear shape, a cross shape, an X shape, etc.

[0138] Exemplarily, the second spray arm 4 can be in a linear shape, a cross shape, an X shape, etc.

[0139] Exemplarily, the shape and size of the first spray arm 3 are different from those of the second spray arm 4. For example, as Figure 16 shown, the shape of the first spray arm 3 is cross-shaped, and the shape of the second spray arm 4 is linear.

[0140] Exemplarily, the shape and size of the first spray arm 3 are the same as those of the second spray arm 4, and they are symmetrically arranged with respect to the rotation axis of the mounting base 2.

[0141] Exemplarily, the shape of the first spray arm 3 is linear, and the shape of the second spray arm 4 is also linear.

[0142] Exemplarily, as Figure 17 shown, the shape of the first spray arm 3 is cross-shaped, and the shape of the second spray arm 4 is also cross-shaped.

[0143] In some examples, as Figure 18 shown, the first spray arm 3 is only connected to one side of the rotation axis of the first rotating shaft 7.

[0144] In other examples, as Figure 19 shown, the first spray arm 3 is symmetrically arranged with respect to the rotation axis of the first rotating shaft 7.

[0145] In this way, the pressures exerted on both sides of the rotation axis of the first spray arm 3 with respect to the first rotating shaft 7 are the same, so that the force on the first rotating shaft 7 is more balanced. Thus, during the rotation of the first rotating shaft 7, the first spray arm 3 can rotate more stably with the first rotating shaft 7, so as to further improve the stability of the dishwasher 10 during operation.

[0146] In some examples, the second spray arm 4 is only connected to one side of the rotation axis of the second rotating shaft 8.

[0147] In other examples, the second spray arm 4 is symmetrically arranged with respect to the rotation axis of the second rotating shaft 8.

[0148] In this way, the pressures exerted on both sides of the rotation axis of the second spray arm 4 with respect to the second rotating shaft 8 are the same, so that the force on the second rotating shaft 8 is more balanced. Thus, during the rotation of the second rotating shaft 8, the second spray arm 4 can rotate more stably with the second rotating shaft 8, so as to further improve the stability of the dishwasher 10 during operation.
